[0130] The following description, in conjunction with the accompanying drawings, clearly and completely describes some embodiments of this disclosure. Obviously, the described embodiments are merely some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments provided in this disclosure are within the scope of protection of this disclosure.

[0131] Unless the context otherwise requires, throughout the specification and claims, the term "comprise" and its other forms, such as the third-person singular "comprises" and the present participle "comprising," are interpreted as open-ended and encompassing, meaning "including, but not limited to." In the description of the specification, terms such as "one embodiment," "some embodiments," "exemplary embodiments," "example," "specific example," or "some examples," etc., are intended to indicate that a particular feature, structure, material, or characteristic associated with that embodiment or example is included in at least one embodiment or example of this disclosure. The illustrative representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics mentioned may be included in any suitable manner in any one or more embodiments or examples.

[0132] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0133] In describing some embodiments, the terms "coupled" and "connected," and their derivative expressions, may be used. The term "connected" should be interpreted broadly; for example, a "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

The term "coupled" or "communicatively coupled" may also refer to two or more components that do not have direct contact with each other but still cooperate or interact with each other. The embodiments disclosed herein are not necessarily limited to the content of this document.

[0134] "At least one of A, B and C" has the same meaning as "at least one of A, B or C", both including the following combinations of A, B and C: only A, only B, only C, combinations of A and B, combinations of A and C, combinations of B and C, and combinations of A, B and C.

[0135] "A and / or B" includes the following three combinations: A only, B only, and a combination of A and B.

[0136] The use of “applies to” or “configured to” in this article implies an open and inclusive language that does not preclude applicability to or configuration to devices that perform additional tasks or steps.

[0137] As used herein, “about,” “approximately,” or “approximately” includes the stated value and the average value within an acceptable range of deviation from the given value, wherein the acceptable range of deviation is determined by a person skilled in the art taking into account the measurement under discussion and the error associated with the measurement of the given quantity (i.e., the limitations of the measurement system).

[0138] As used herein, “parallel,” “perpendicular,” and “equal” include the described situation and situations that are similar to the described situation, within an acceptable range of deviation, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, “parallel” includes absolute parallelism and approximate parallelism, where an acceptable range of deviation for approximate parallelism may be, for example, within 5°; “perpendicular” includes absolute perpendicularity and approximate perpendicularity, where an acceptable range of deviation for approximate perpendicularity may also be, for example, within 5°; “equal” includes absolute equality and approximate equality, where an acceptable range of deviation for approximate equality may be, for example, a difference between the two equals being less than or equal to 5% of either one.

[0139] Typically, the compressor, condenser, and evaporator in portable air conditioners are disorganized, leading to longer heat exchange times and lower heat exchange efficiency. Furthermore, portable air conditioners often have a low airflow area, typically blowing air towards the user's hips and lower back, resulting in poor indoor air circulation and affecting cooling performance.

[0140] To address the aforementioned issues, some embodiments of this disclosure provide a portable air conditioner 100.

[0141] The Portable Air Conditioner 100 is an air conditioner that integrates the indoor and outdoor units and is portable. The Portable Air Conditioner 100 houses the compressor, condenser, evaporator, and other components within a single enclosure, thus achieving both cooling and heating functions.

[0142] In some embodiments, as shown in FIG1, the portable air conditioner 100 includes a housing 10.

[0143] In some embodiments, as shown in FIG18, the portable air conditioner 100 further includes a receiving space 14 located within the housing 10.

[0144] In some embodiments, as shown in FIG3, the portable air conditioner 100 further includes an outdoor air duct assembly 20, which is located in the receiving space 14.

[0145] In some embodiments, as shown in Figures 7 and 8, the portable air conditioner 100 further includes an indoor air duct assembly 40 located in the receiving space 14.

[0146] In some embodiments, as shown in FIG5, the portable air conditioner 100 further includes an electrical control box 50 located in the accommodating space 14.

[0147] It should be noted that the outer casing 10 serves to protect the outdoor air duct assembly 20, the indoor air duct assembly 40, and the electrical control box 50. In some embodiments, the portable air conditioner 100 also includes a refrigerant circuit 17.

[0148] In some embodiments, as shown in FIG3, the refrigerant circuit 17 includes a compressor 30, which is the core component of the refrigerant circuit 17. It can draw in low-temperature and low-pressure refrigerant gas and compress it into high-temperature and high-pressure gas.

[0149] In some embodiments, as shown in FIG3, the refrigerant circuit 17 includes an outdoor heat exchanger 60, which can be a condenser. For example, the compressor 30 can compress the gas into a high-temperature and high-pressure gas and cool it into a high-pressure liquid. A large amount of heat will be released in this process, and the outdoor air duct assembly 20 is usually used to dissipate heat.

[0150] In some embodiments, as shown in FIG3, the refrigerant circuit 17 further includes an indoor heat exchanger 70. In this way, the indoor heat exchanger 70 can act as an evaporator, which can evaporate the high-pressure liquid into low-temperature and low-pressure steam. In this process, it will absorb heat from the surrounding environment, which is beneficial to improving the cooling effect of the portable air conditioner 100.

[0151] Thus, in the refrigerant circuit 17, the compressor 30, outdoor heat exchanger 60 and indoor heat exchanger 70 connected end to end transfer heat and convert energy through refrigerant fluid, thereby achieving the purpose of refrigeration.

[0152] In some embodiments, the outdoor air duct assembly 20 is disposed on one side of the outdoor heat exchanger 60, thereby delivering outdoor air to the outdoor heat exchanger 60 for heat exchange. In this way, by passing outdoor air through the outdoor heat exchanger 60 for heat exchange, pollutants such as dust and bacteria in the outdoor air can be filtered out, thereby improving outdoor air quality. Furthermore, it can reduce the load on the outdoor air conditioning system, thereby reducing energy consumption and achieving the goal of energy conservation and emission reduction.

[0153] In some embodiments, heat exchange is performed through the outdoor heat exchanger 60, which can reduce the impact of outdoor temperature and humidity on the indoor environment, thereby increasing the reliability of the portable air conditioner 100.

[0154] For example, the indoor air duct assembly 40 is located on one side of the indoor heat exchanger 70, which can deliver indoor air to the indoor heat exchanger 70 for heat exchange, thereby transferring the heat of the indoor air to the outside, achieving the functions of regulating indoor temperature and purifying indoor air.

[0155] In some embodiments, as shown in Figures 6 and 8, the electrical control box 50 is connected to the compressor 30, the outdoor air duct assembly 20, and the indoor air duct assembly 40, respectively. In this way, the electrical control box 50 is electrically connected to the compressor 30, the outdoor air duct assembly 20, and the indoor air duct assembly 40, respectively, so that the electrical control box 50 can control the on / off of the circuits of the compressor 30, the outdoor air duct assembly 20, and the indoor air duct assembly 40, thereby enabling the portable air conditioner 100 to operate normally.

[0156] For example, as shown in Figures 5 and 6, the compressor 30 and the electrical control box 50 are spaced apart in the horizontal direction of the accommodating space 14, which helps to reduce interference between the compressor 30 and the electrical control box 50.

[0157] In some embodiments, as shown in Figures 6 and 10, the outdoor heat exchanger 60, indoor heat exchanger 70, outdoor air duct assembly 20, and indoor air duct assembly 40 are disposed above the compressor 30 and the electrical control box 50. In this way, by making reasonable use of the internal space of the portable air conditioner 100, the compressor 30 and the electrical control box 50 are separated from the outdoor heat exchanger 60, indoor heat exchanger 70, outdoor air duct assembly 20, and indoor air duct assembly 40, respectively, forming an independent module. This not only facilitates maintenance and replacement but also improves the heat exchange efficiency of the portable air conditioner 100.

[0158] In some embodiments, as shown in Figures 3 and 4, the outdoor heat exchanger 60 and the outdoor air duct assembly 20 are disposed above the compressor 30 and the electrical control box 50, and the outdoor heat exchanger 60 and the outdoor air duct assembly 20 are arranged in the horizontal direction of the accommodating space 14. The indoor heat exchanger 70 and the indoor air duct assembly 40 are disposed above the outdoor heat exchanger 60 and the outdoor air duct assembly 20, and the indoor heat exchanger 70 and the indoor air duct assembly 40 are arranged in the horizontal direction of the accommodating space 14.

[0159] For example, arranging the outdoor heat exchanger 60 and the outdoor air duct assembly 20 in the horizontal direction of the accommodating space 14 can accelerate the air delivery speed of the outdoor heat exchanger 60, thereby improving the heat exchange efficiency of the outdoor heat exchanger 60. Furthermore, arranging the outdoor heat exchanger 60 and the outdoor air duct assembly 20 in the horizontal direction of the accommodating space 14 can reduce the distance between the outdoor heat exchanger 60 and the outdoor air duct assembly 20, and also increase the height of the portable air conditioner 100, thereby improving the stability of the portable air conditioner 100 during operation.

[0160] For example, the indoor heat exchanger 70 and the indoor air duct assembly 40 are positioned above the outdoor heat exchanger 60 and the outdoor air duct assembly 20, which can reduce interference and shorten the heat exchange distance.

[0161] It should be noted that the indoor heat exchanger 70 and the indoor air duct assembly 40 are arranged in the horizontal direction of the accommodating space 14. Similarly, the indoor air duct assembly 40 can accelerate the air delivery speed of the indoor heat exchanger 70, thereby improving the heat exchange efficiency of the indoor heat exchanger 70. It can also reduce the distance between the indoor heat exchanger 70 and the indoor air duct assembly 40, and increase the height of the portable air conditioner 100. This allows the air delivery area of ​​the air outlet 12 of the indoor air duct assembly 40 to be higher than that of a traditional portable air conditioner 100. This makes it easier for users to perceive the air delivery and also raises the center of gravity of the portable air conditioner 100, ensuring greater stability during operation.

[0162] In this way, the compressor 30 and the electrical control box 50 are located at the bottom layer of the portable air conditioner 100, the outdoor heat exchanger 60 and the outdoor air duct assembly 20 are located in the middle of the portable air conditioner 100, that is, the second layer, and the indoor heat exchanger 70 and the indoor air duct assembly 40 are located on the upper layer of the portable air conditioner 100, that is, the third layer. In this way, a multi-layer distribution can be achieved inside the portable air conditioner 100, which has the advantages of hierarchical design and can also help reduce the width and thickness of the portable air conditioner 100.

[0163] Furthermore, the air inlet pipe 43 and air outlet pipe 44 of the portable air conditioner 100 are located behind the indoor heat exchanger 70, which not only makes reasonable use of space but also improves the heat exchange efficiency of the indoor heat exchanger 70.

[0164] According to some embodiments of this disclosure, as shown in FIG28, the portable air conditioner 100 further includes a first water receiving tray 80, and an outdoor heat exchanger 60 is disposed on the first water receiving tray 80.

[0165] According to some embodiments of the present disclosure, as shown in Figures 15 and 16, the portable air conditioner 100 further includes a support plate 81 disposed in the receiving space 14, and the support plate 81 is located between the control box 50 and the compressor 30. The support plate 81 extends in the vertical direction and is supported between the first water receiving tray 80 and the bottom of the outer casing 10.

[0166] For example, the outdoor heat exchanger 60 is installed on the first water receiving pan 80, so that the condensate produced by the outdoor heat exchanger 60 or the indoor heat exchanger 70 after heat exchange can flow onto the first water receiving pan 80, thereby preventing the condensate produced by the outdoor heat exchanger 60 from flowing out of the outer casing 10 of the portable air conditioner 100.

[0167] It should be noted that the first drip tray 80 is designed to store condensate, preventing the condensate generated by the outdoor heat exchanger 60 from overflowing and affecting the stability of the internal circuitry of the portable air conditioner 100.

[0168] For example, the support plate 81 is located between the control box 50 and the compressor 30, which can isolate the control box 50 and the compressor 30, thereby ensuring the safety and stability of the circuit transmission of the control box 50.

[0169] It should be noted that the support plate 81 is supported between the bottom of the first water receiving tray 80 and the bottom of the outer shell 10. In this way, the support plate 81 can support the bottom of the first water receiving tray 80 and the outer shell 10, thereby increasing the strength and stability of the first water receiving tray 80 and improving the strength of the bottom of the outer shell 10.

[0170] In some embodiments, as shown in Figures 15 and 16, the support plate 81 includes a main board 811, which is disposed between the control box 50 and the compressor 30, thereby increasing the structural stability of the control box 50 and the compressor 30 on the chassis 16.

[0171] In some embodiments, as shown in Figures 15 and 16, the support plate 81 further includes a first side plate 812. The first side plate 812 is disposed at both ends of the main plate 811 in the horizontal direction, and the first side plate 812 is bent relative to the main plate 811. At least one of the main plate 811 and the first side plate 812 is supported between the first water receiving tray 80 and the chassis 16. This not only increases the support area of ​​the support plate 81 and the bottom of the first water receiving tray 80, preventing the first water receiving tray 80 from tilting relative to the horizontal plane, but also improves the structural stability of the first water receiving tray 80, effectively preventing water from spilling out of the first water receiving tray 80. In addition, the main plate 811 and the first side plate 812 can surround the compressor 30 to prevent the compressor 30 from shaking, which is beneficial to ensuring the safety of the compressor 30 during the movement of the portable air conditioner 100.

[0172] It should be noted that, as shown in Figure 16, there are two first side plates 812. The two first side plates 812 are respectively disposed at both ends of the main board 811 in the horizontal direction. The two first side plates 812 are bent and extended relative to the main board 811 toward the adjacent compressor 30. The two first side plates 812 are respectively disposed on both sides of the compressor 30.

[0173] For example, a first side plate 812 is set at each of the two ends of the main board 811 in the horizontal direction. On the one hand, the support plate 81 can be set around the compressor 30 in a circumferential direction, which can improve the reliability of the protection function of the support plate 81 for the compressor 30. On the other hand, the bottom surface of the first water receiving tray 80 can be limited, which can prevent the first water receiving tray 80 from tilting relative to the horizontal plane during the movement of the mobile air conditioner 100.

[0174] For example, the two first side plates 812 are bent and extended relative to the main board 811 toward the adjacent compressor 30, and the two first side plates 812 are respectively disposed on both sides of the compressor 30. This not only protects the compressor 30, but also enhances the structural strength of the support plate 81 and improves the structural reliability of the support plate 81.

[0175] In some embodiments, as shown in Figures 15 and 16, the control box 50 is open on the side facing the compressor 30, and the main board 811 is covered on the open side of the control box 50. The main board 811 is provided with a heat dissipation grille 8111, which corresponds to the heat sink 51 in the control box 50.

[0176] It should be noted that the control box 50 and the compressor 30 are mounted on the chassis 16, with the control box 50 open on the side facing the compressor 30. By using the main board 811 positioned between the control box 50 and the compressor 30, the main board 811 can cover the open side of the control box 50 facing the compressor 30. This reduces the number of components in the control box 50, helps to shorten the distance between the control box 50 and the compressor 30, and thus improves the structural compactness of the portable air conditioner 100. In addition, the main board 811 can separate the control box 50 and the compressor 30.

[0177] It should be noted that the motherboard 811 is equipped with a heat dissipation grille 8111 to dissipate heat from the control box 50. When the motherboard 811 is placed on the side of the control box 50 that faces the compressor 30, the heat dissipation grille 8111 on the motherboard 811 corresponds to the heat sink 51 in the control box 50. This allows the heat generated by the operation of the control box 50 to be transferred from the heat sink 51 to the heat dissipation grille 8111, and then to the air. This enables the control box 50 to dissipate heat quickly and extends its service life.

[0178] In some embodiments, as shown in Figures 14, 15, and 16, the portable air conditioner 100 further includes an outdoor air duct component 21. The outdoor air duct component 21 is disposed above the compressor 30 and is horizontally spaced from the outdoor heat exchanger 60. An outdoor fan 22 is disposed within the outdoor air duct component 21 and is correspondingly connected to the outdoor heat exchanger 60. For example, the outdoor air duct component 21 and the outdoor heat exchanger 60 are both disposed above the compressor 30, which facilitates the arrangement of the space 14 and improves the structural compactness of the portable air conditioner 100.

[0179] In addition, the outdoor air duct component 21 and the outdoor heat exchanger 60 are arranged at intervals in the horizontal direction and are connected to each other. This not only ensures that the outdoor air duct component 21 and the outdoor heat exchanger 60 are set independently, but also facilitates heat exchange between the air in the outdoor air duct component 21 and the outdoor heat exchanger 60, thereby improving the working efficiency of the outdoor heat exchanger 60.

[0180] For example, the outdoor air duct 21 can limit the direction and path of air flow in the outdoor air duct 21, and the outdoor fan 22 is installed in the outdoor air duct 21 to provide power for the air in the outdoor air duct 21.

[0181] In the embodiments of this disclosure, at least a portion of the support plate 81 and the outdoor air duct component 21 are integrally formed structural components. This not only facilitates the production of the outdoor air duct component 21 and the support plate 81, thus improving the production convenience of the portable air conditioner 100, but also improves the structural compactness of the portable air conditioner 100, thereby enhancing the structural strength of the portable air conditioner 100.

[0182] In some embodiments, as shown in Figures 15 and 16, the outdoor duct component 21 includes a first duct plate 412. The outdoor duct component 21 also includes a second duct plate 413. The first duct plate 412 and the second duct plate 413 are disposed opposite to each other and connected to form an air duct for airflow in the outdoor duct component 21. The second duct plate 413 is located between the first duct plate 412 and the outdoor heat exchanger 60, and the second duct plate 413 and the support plate 81 are integrally formed structural components. This allows the second duct plate 413 and the support plate 81 to be manufactured as a single unit, which not only improves the production convenience of the second duct plate 413 and the support plate 81, but also facilitates the positioning of the support plate 81 during assembly of the second duct plate 413 and the first duct plate 412. This improves the assembly convenience of the portable air conditioner 100 and helps to increase the production efficiency of the portable air conditioner 100.

[0183] In some embodiments, as shown in Figures 9, 17, 18, and 19, the portable air conditioner 100 further includes an indoor air duct 41, which defines the direction and path of airflow within the indoor air duct 41. The indoor heat exchanger 70 and the indoor air duct 41 are positioned above the outdoor heat exchanger 60, which not only facilitates improved structural compactness within the housing 10 but also ensures that the indoor heat exchanger 70 is positioned above the second drip tray 88.

[0184] When the refrigerant absorbs heat and evaporates in the indoor heat exchanger 70, the surface temperature of the indoor heat exchanger 70 decreases. Water vapor in the air condenses on the surface of the indoor heat exchanger 70, causing the condensate to fall into the second drip tray 88 below. The condensate is then discharged through a drain pipe on the second drip tray 88. In this way, a second drip tray 88 can be used to collect the condensate from the outdoor heat exchanger 60 and the indoor heat exchanger 70, improving the structural compactness of the outer casing 10.

[0185] It should be noted that the indoor air duct component 41 and the indoor heat exchanger 70 are arranged at intervals in the horizontal direction, and the indoor air duct component 41 and the indoor heat exchanger 70 are connected to each other. In this way, not only can the indoor heat exchanger 70 and the indoor air duct component 41 be set independently, but it can also facilitate the exchange of heat between the air in the indoor air duct component 41 and the indoor heat exchanger 70, thereby improving the working efficiency of the indoor heat exchanger 70.

[0186] In some embodiments, as shown in FIG6, the portable air conditioner 100 includes at least one support beam 93.

[0187] For example, at least one support beam 93 includes a support beam 93. The support beam 93 extends in the vertical direction, and its two ends are connected to the chassis 16 and the indoor air duct component 41, respectively. In this way, the support beam 93 can support the chassis 16 and the indoor air duct component 41, which helps to improve the structural stability of the indoor air duct component 41 in the portable air conditioner 100.

[0188] In some embodiments, as shown in Figures 17, 18, and 19, the support beam 93 includes a first support segment 931. The first support segment 931 extends in the vertical direction, and its lower end is connected to the chassis 16, thereby fixing the support beam 93 to the chassis 16 to provide reliable support for the indoor air duct component 41.

[0189] In some embodiments, as shown in Figures 17, 18, and 19, the support beam 93 further includes a second support section 932, which is connected to the upper end of the first support section 931 so that the second support section 932 is fixed on the first support section 931. The second support section 932 is also connected to the indoor air duct component 41. This arrangement allows the second support section 932 to provide reliable support for the indoor air duct component 41, preventing the indoor air duct component 41 from shaking in the portable air conditioner 100, improving the structural stability of the indoor air duct component 41, and thus enhancing the structural reliability of the portable air conditioner 100.

[0190] For example, the second support section 932 is bent relative to the first support section 931 and extends in the horizontal direction. This arrangement can extend the second support section 932 in the horizontal direction to increase the contact area between the second support section 932 and the indoor air duct component 41, thereby increasing the connection strength between the second support section 932 and the indoor air duct component 41 and improving the structural stability of the indoor air duct component 41.

[0191] In some embodiments, as shown in Figures 17, 18 and 19, a first positioning part 9321 is provided on the support beam 93, and a second positioning part 23 is provided on the indoor air duct component 41. One of the first positioning part 9321 and the second positioning part 23 is a positioning protrusion, and the other is a positioning hole. The positioning protrusion and the positioning hole are positioned and engaged.

[0192] For example, the support beam 93 and the indoor air duct component 41 can be quickly positioned by the first positioning part 9321 and the second positioning part 23, which can facilitate the installation of the support beam 93 and the indoor air duct component 41, improve the assembly convenience of the portable air conditioner 100, shorten the installation time, and improve work efficiency.

[0193] It should be noted that after the positioning of the first positioning part 9321 and the second positioning part 23, the position of the support beam 93 relative to the indoor air duct component 41 can be determined, which makes it easier for the chassis 16 to connect with the bottom of the support beam 93. In this way, it is easier to determine the frame structure of the portable air conditioner 100 during the assembly process, which helps to improve the assembly efficiency of the portable air conditioner 100.

[0194] For example, the positioning fit between the first positioning part 9321 and the second positioning part 23 is actually a positioning fit between the positioning hole and the positioning protrusion. With this setting, the positioning hole and the positioning protrusion are not only simple in structure and easy to process, but also can achieve rapid positioning, which can improve the positioning efficiency and assembly efficiency of the mobile air conditioner 100.

[0195] In some embodiments, as shown in Figures 17 and 18, at least one support beam 93 includes two support beams 93. The two support beams 93 are respectively disposed on both sides of the indoor air duct component 41, thereby supporting both sides of the indoor air duct component 41.

[0196] For example, the indoor air duct component 41 can be fixed above the outdoor heat exchanger 60 to ensure the structural stability of the indoor air duct component 41 in the portable air conditioner 100, thereby improving the working stability of the portable air conditioner 100.

[0197] In some embodiments, as shown in Figures 37, 38, and 44, the housing 10 includes a main housing 15. The housing 10 also includes a chassis 16. The chassis 16 is disposed at the bottom of the main housing 15 and serves a supporting function.

[0198] In some embodiments, as shown in FIG27, the portable air conditioner 100 further includes wheels 18. The wheels 18 are disposed at the bottom of the chassis 16.

[0199] Understandably, during the use of the portable air conditioner 100, the wheels 18 are located between the chassis 16 and the ground. This makes full use of the bottom space of the chassis 16, optimizes the setting position of the wheels 18, and reduces the overall space occupied by the portable air conditioner 100.

[0200] To prevent the portable air conditioner 100 from relying solely on its wheels 18 for contact with the ground, which could affect its stability and cause it to tip over under load, in some embodiments, as shown in Figure 38, a slot 161 is provided on the chassis 16. The portable air conditioner 100 may also include support legs 24. By inserting a portion of the support leg 24 into the slot 161 and having the other portion located on the outside of the chassis 16, the support leg 24 can provide circumferential support to the ground when the portable air conditioner 100 tilts. The supporting force is transmitted to the chassis 16 through the support leg 24, thus providing overall support for the portable air conditioner 100. In this way, the support leg 24 can reduce the likelihood of the portable air conditioner 100 tipping over, improve its stability, and extend its service life.

[0201] In some embodiments, as shown in Figures 38 and 39, a first latching portion 162 is provided in the slot 161, and a second latching portion 241 is provided on the support leg 24. The first latching portion 162 and the second latching portion 241 engage with each other. This allows for a detachable connection between the support leg 24 and the chassis 16. Users can selectively mount the support leg 24 onto the chassis 16 or remove it from the chassis 16 according to their actual needs, thus meeting their usage requirements in different scenarios.

[0202] For example, when the user is using the portable air conditioner 100 normally, the support legs 24 can be placed on the chassis 16 to prevent the portable air conditioner 100 from tipping over. When the user moves the portable air conditioner 100, the support legs 24 can be removed to reduce the horizontal dimensions of the portable air conditioner 100 and improve its maneuverability.

[0203] For example, the slot 161 can be set on the side wall of the chassis 16, and the first snap-fit ​​part 162 is located on the bottom wall of the chassis 16. This allows the support leg 24 to be disassembled and installed from the circumferential side, which not only makes it convenient for users to disassemble and install the support leg 24, but also allows the support leg 24 to support the portable air conditioner 100 from the circumferential outside, improving the reliability of the support leg 24 in supporting the portable air conditioner 100.

[0204] In some embodiments, as shown in Figures 38 and 39, the first snap-fit ​​portion 162 is a snap hole, and the second snap-fit ​​portion 241 is a snap fastener. The snap fastener is located above the snap hole and can be elastically brought closer to or away from the chassis 16 so that the snap fastener and the snap hole can be selectively engaged.

[0205] Understandably, this allows the buckle to engage with the card hole simply by inserting it into the hole, thus achieving the engagement between the first engaging part 162 and the second engaging part 241. This improves both the speed and accuracy of the engagement between the first engaging part 162 and the second engaging part 241, and also enhances the stability of the engagement between them.

[0206] For example, by placing the locking hole on the lower side of the slot 161 and the latch on the lower side of the support leg 24, the latch can be inserted into the slot 161 first, so that the latch is positioned above the locking hole. On the one hand, the latch can be elastically moved away from the chassis 16 to achieve a locking engagement between the latch and the locking hole; on the other hand, it allows the user to easily apply force to the latch, causing it to elastically move closer to the chassis 16 to release the locking engagement between the latch and the locking hole.

[0207] In some embodiments, as shown in Figures 37, 38, and 39, the support leg 24 includes a support body 242. The support body 242 is inserted into the slot 161. The support leg 24 also includes a snap-fit ​​piece 243. The support body 242 has a first clearance groove 2421, and the snap-fit ​​piece 243 is disposed in the first clearance groove 2421. One end of the snap-fit ​​piece 243 is elastically connected to the support body 242, and a latch is provided on the side of the snap-fit ​​piece 243 adjacent to the snap-fit ​​hole.

[0208] Taking the support leg 24 mounted on the chassis 16 as an example, simply insert the support leg body 242 into the slot 161. During insertion, the latch is restricted by the slot 161, causing the snap-fit ​​piece 243 to undergo elastic deformation, moving the latch away from the chassis 16. As the support leg body 242 continues to be inserted, the latch moves above the snap-fit ​​hole, the restriction of the slot 161 on the latch disappears, the snap-fit ​​piece 243 releases its elastic deformation, and moves the latch away from the chassis 16, achieving the snap-fit ​​engagement between the latch and the snap-fit ​​hole.

[0209] Taking the removal of the support leg 24 from the chassis 16 as an example, force can be applied to the buckle to cause the buckle to cause the snap-fit ​​piece 243 to deform elastically, so that the buckle moves closer to the chassis 16 and exits the snap hole, thereby making it easier to move the support leg 24 out of the slot 161 and release the snap-fit ​​between the buckle and the snap hole.

[0210] In this way, the structural design of the support leg 24 can be optimized, which not only makes it easier for users to disassemble and assemble the support leg 24, but also improves the structural reliability of the support leg 24, ensuring that the support leg 24 can be disassembled and assembled multiple times without damage, and increasing the service life of the support leg 24.

[0211] It should be noted that, as shown in Figures 38 and 39, the buckle is provided with a first guide surface 2411, which selectively guides and engages with the side wall of the corresponding buckle hole on the chassis 16.

[0212] For example, the first guide surface 2411 is located at the end of the buckle adjacent to the snap-fit ​​piece 243 and the support body 242 that are elastically connected. In this way, when the support body 242 is inserted into the slot 161, the first guide surface 2411 can guide and cooperate with the side wall of the chassis 16 where the corresponding snap hole is located, which can facilitate the gradual insertion of the support body 242 into the slot 161 and improve assembly efficiency.

[0213] For example, the first guide surface 2411 is a guide slope, and no specific restrictions are imposed here.

[0214] In some embodiments, as shown in Figures 38 and 39, the other end of the snap-fit ​​piece 243 is provided with a limiting protrusion 244, which is spaced apart from the snap fastener and engages with the side wall of the chassis 16 for limiting.

[0215] For example, by providing a limiting protrusion 244 at a distance from the latch at the other end of the snap-fit ​​piece 243, after the support piece body 242 is inserted into the slot 161 and the latch engages with the latch hole, the snap-fit ​​piece 243 moves the limiting protrusion 244 away from the chassis 16, and the side wall of the limiting protrusion 244 engages with the side wall of the chassis 16. This limits further insertion of the support piece body 242 relative to the slot 161, reminding the user that the correct assembly position has been reached, preventing over-assembly and thus avoiding failure of the engagement between the latch and the latch hole, thereby improving assembly reliability.

[0216] It should be noted that since the limiting protrusion 244 is closer to the outer side than the buckle, when removing the support leg 24 from the chassis 16, the user can apply force to the limiting protrusion 244 to cancel the engagement between the buckle and the buckle hole, which facilitates the user's operation.

[0217] In some embodiments, as shown in Figures 38 and 39, a second guide surface 2441 is provided near one end of the latch of the limiting protrusion 244, and the second guide surface 2441 selectively guides and engages with the side wall of the chassis 16.

[0218] It should be noted that by setting a second guide surface 2441 near the end of the latch of the limiting protrusion 244, after the support body 242 is inserted into the slot 161 and is in the correct assembly position, the second guide surface 2441 can guide and cooperate with the side wall of the chassis 16, which can prevent the side wall of the chassis 16 corresponding to the latch hole from restricting the rebound of the limiting protrusion 244 and even the latching piece 243, thereby ensuring the correct assembly of the support leg 24.

[0219] For example, the second guide surface 2441 can be a guide arc surface. This ensures that the second guide surface 2441 plays a guiding role, while also preventing the limiting protrusion 244 from having a sharp structure. Users can apply force to the limiting protrusion 244 to cancel the engagement between the buckle and the buckle hole, which helps to avoid causing discomfort to the user's hand or even scratching the user's hand.

[0220] In some embodiments, as shown in Figures 37 to 39, the support leg 24 includes a first support leg portion 245, which is inserted into the slot 161 and extends horizontally. The end of the first support leg portion 245 away from the slot 161 extends at least partially out of the slot 161.

[0221] The support leg 24 also includes a second support leg 246, which is disposed at the end of the first support leg 245 away from the slot 161. The second support leg 246 extends downward relative to the first support leg 245, and the lower end of the second support leg 246 is used to support the air conditioner 100 in contact with the ground when it is tilted.

[0222] In this way, the structural design of the support legs 24 can be optimized, allowing the first support leg 245 to adapt to the horizontal distance of the portable air conditioner 100, and the second support leg 246 to adapt to the distance between the chassis 16 and the ground. Thus, when the portable air conditioner 100 tilts, the lower end of the second support leg 246 can contact the ground for support, and the force can be transmitted sequentially through the second support leg 246 and the first support leg 245 to the chassis 16, providing overall support for the portable air conditioner 100 and preventing it from tipping over.

[0223] It should be noted that the cross-section of the second support 246 is triangular, and the horizontal cross-sectional area of ​​the second support 246 gradually decreases from top to bottom. This optimizes the structural design of the second support 246, not only improving its structural strength but also enhancing the connection strength between the second support 246 and the first support 245.

[0224] In this way, the overall force transmission performance of the support leg 24 can be improved, providing a more stable and reliable support force for the portable air conditioner 100 when it is tilted, avoiding insufficient support force of the support leg 24, thus more reliably preventing the portable air conditioner 100 from tipping over, which is conducive to improving the structural reliability of the portable air conditioner 100.

[0225] In some embodiments, as shown in Figures 37 to 39, a plurality of slots 161 are provided on the chassis 16, and the plurality of slots 161 are spaced apart on the circumferential sidewall of the chassis 16. Correspondingly, there are a plurality of legs 24, and the plurality of legs 24 correspond to the plurality of slots 161.

[0226] Understandably, users can place multiple support legs 24 at intervals on the circumferential sidewalls of the chassis 16. No matter where the portable air conditioner 100 tilts in the circumferential direction, at least one support leg 24 can contact the ground for support, thereby more reliably preventing the portable air conditioner 100 from tipping over and improving the structural reliability of the portable air conditioner 100.

[0227] According to some embodiments of this disclosure, as shown in Figures 33 and 34, a first water receiving tray 80 is disposed above the compressor 30, and an outdoor air duct assembly 20 is disposed above the electrical control box 50.

[0228] For example, the first water receiving tray 80 is located above (directly above) the compressor 30, which can not only isolate the outdoor air duct assembly 20 and the electrical control box 50, but also isolate the outdoor heat exchanger 60 and the compressor 30. In this way, the compressor 30 and the electrical control box 50 are located on the bottom layer, and the outdoor air duct assembly 20 and the outdoor heat exchanger 60 are located on the second layer, thus forming a two-layer structure and avoiding interference.

[0229] For example, the outdoor heat exchanger 60 is arranged opposite to the compressor 30, and the outdoor heat exchanger 60 is located above (directly above) the compressor 30. In this way, the corresponding arrangement of the outdoor heat exchanger 60 and the compressor 30 can better prevent the condensate at the outdoor heat exchanger 60 from flowing to the electrical control box 50, thereby improving the safety and stability of the circuit transmission of the electrical control box 50.

[0230] For example, the outdoor air duct assembly 20 is positioned above the electrical control box 50, which shortens the distance between the electrical control box 50 and the outdoor air duct assembly 20 for circuit connection, thereby preventing the wiring from getting tangled and improving the stability of the wiring connection.

[0231] A second water tank 801 is provided on the first water receiving tray 80. The second water tank 801 can not only be configured to store the condensate dripping from the outdoor heat exchanger 60, but also guide the flow direction and path of the condensate in the first water receiving tray 80.

[0232] In some embodiments, as shown in Figures 28 and 33, the portable air conditioner 100 further includes a water-spraying device 87. The water-spraying device 87 includes a water-spraying component disposed in a second water tank 801 and capable of rotation. This allows water in the second water tank 801 to be lifted above a first water receiving tray 80, so that the water falls onto the surface of the outdoor heat exchanger 60. This wets the outdoor heat exchanger 60, cooling it and improving its heat dissipation efficiency. Consequently, it increases the heat exchange capacity of the refrigerant in the outdoor heat exchanger 60, thereby enhancing the cooling or heating capacity of the portable air conditioner 100. It should be noted that in some embodiments of this disclosure, the water-spraying component can be a water-spraying wheel 871.

[0233] The portable air conditioner 100 also includes a water-discharging drive component 872. The water-discharging drive component 872 is disposed on the first water receiving tray 80 and is connected to the water-discharging component in a driving connection. This not only allows the first water receiving tray 80 to provide a reliable setting position for the water-discharging drive component 872 and the water-discharging component, but also allows the water-discharging drive component 872 to drive the water-discharging component to rotate, so that the water-discharging component can lift the water in the second water tank 801 onto the outdoor heat exchanger 60.

[0234] For example, a partition 802 and a baffle 803 are provided in the second water tank 801 of the first water receiving tray 80. The partition 802 extends in the length direction of the second water tank 801, which can divide the second water tank 801 into a water-spraying tank 8011 and a water-returning tank 8012 in the width direction. The water-spraying component corresponds to the water-spraying tank 8011 and can rotate in the water-spraying tank 8011, so that the water in the water-spraying tank 8011 can be lifted to the outdoor heat exchanger 60.

[0235] The partition 802 has two ends along its length, and a first opening 8021 is provided at the first end along its length. This allows the water inlet trough 8011 and the return trough 8012 to communicate with each other at both ends along the length of the first water receiving tray 80, so that water in the water inlet trough 8011 and the return trough 8012 can flow back to the water inlet trough 8011, thereby allowing the water in the water inlet trough 8011 to continuously store water.

[0236] For example, a baffle 803 is provided on the side of the first opening 8021 away from the partition 802. The baffle 803 extends into the second water tank 801, which allows water at one end of the second water tank 801 along its length to flow towards the middle of the second water tank 801, allowing water to accumulate in the middle of the second water tank 801. This, in turn, allows water in the first water receiving tray 80 to concentrate in the water-filling trough 8011 and the water-returning trough 8012. Since the water-filling trough 8011 and the water-returning trough 8012 are connected, this arrangement allows water in the first water receiving tray 80 to continuously flow into the water-filling trough 8011, thereby increasing the water storage capacity of the water-filling trough 8011.

[0237] Therefore, by setting an inclined baffle 803 to guide the water in the water-pumping tank 8011 to the water-returning tank 8012, the water can flow back to the water-pumping tank 8011 as quickly as possible. This allows the water-pumping component to continuously lift the water in the water-pumping tank 8011 to continuously dissipate heat from the outdoor heat exchanger 60, thereby improving the heat exchange efficiency of the outdoor heat exchanger 60 and enhancing the working performance of the portable air conditioner 100.

[0238] In some embodiments, as shown in Figures 34 and 35, the second water tank 801 has a first sidewall 804. The second water tank 801 also has a second sidewall 805. The first sidewall 804 and the second sidewall 805 are spaced apart in the width direction of the second water tank 801. A water inlet trough 8011 is formed between the partition 802 and the first sidewall 804, and a water return trough 8012 is formed between the partition 802 and the second sidewall 805. One end of the baffle 803 is connected to the first sidewall 804, and a gap is left between the other end of the baffle 803 and the second sidewall 805.

[0239] For example, the first sidewall 804 and the second sidewall 805 are respectively disposed on both sides of the second water tank 801 in the width direction to fix the structure of the second water tank 801. The first sidewall 804 and the partition 802 define the water inlet trough 8011, and the second sidewall 805 and the partition 802 define the water return trough 8012. This helps to improve the structural reliability of the water inlet trough 8011 and the water return trough 8012 on the first water receiving tray 80.

[0240] It should be noted that one end of the baffle 803 is connected to the first side wall 804, which can provide a stable and reliable setting position for the baffle 803. Furthermore, the baffle 803 extends from the first side wall 804 into the interior of the second water tank 801, which can guide the water in the water tank 8011 to flow into the return water tank 8012.

[0241] A gap is left between the other end of the baffle 803 and the second side wall 805, so that the water in the second water tank 801 can flow to other places in the first water receiving tray 80. This can prevent the baffle 803 from blocking the second water tank 801, and can ensure the water holding capacity of the first water receiving tray 80, so as to prevent the water in the second water tank 801 from being too full and causing the first water receiving tray 80 to overflow.

[0242] In some embodiments, as shown in Figures 34 and 35, in the width direction of the second water tank 801, the baffle 803 extends obliquely from one end toward the direction away from the water-spraying component. This arrangement allows the baffle 803 to avoid the water-spraying component and its spray range, resulting in more water falling into the water-spraying tank 8011. This, in turn, increases the amount of water flowing into the return water tank 8012, thereby increasing the water supply from the return water tank 8012 to the water-spraying tank 8011, which in turn enhances the heat dissipation effect of the outdoor heat exchanger 60.

[0243] On the other hand, it can reduce the resistance of the baffle 803 to the water, make the water flow in the second water tank 801 smoother, reduce the water splashed out of the second water tank 801 when it collides with the baffle 803, and thus allow more water in the second water tank 801 to flow to the return water tank 8012, thereby increasing the water storage in the water pumping tank 8011, so that the water pumping component can continuously pump water to the outdoor heat exchanger 60.

[0244] In some embodiments, as shown in FIG34, the baffle 803 includes an inclined plate segment 8031. One end of the inclined plate segment 8031 ​​is connected to the first sidewall 804, thereby fixing the position of the baffle 803 in the second water tank 801. The other end of the inclined plate segment 8031 ​​extends inclined away from the water agitator to guide the water flow from the end of the water agitator 8011 away from the water agitator to the return water tank 8012, thereby increasing the amount of water in the return water tank 8012 and thus increasing the amount of water flowing back to the return water tank 8012.

[0245] The baffle 803 also includes an arc-shaped plate segment 8032, which is disposed at the other end of the inclined plate segment 8031, and the arc-shaped plate segment 8032 is curved relative to the inclined plate segment 8031 ​​toward the side facing the return water tank 8012.

[0246] In the embodiments of this disclosure, the open side of the arc-shaped plate segment 8032 is open towards the return water tank 8012. This arrangement allows the water flowing along the inclined plate segment 8031 ​​to continue flowing along the arc-shaped plate segment 8032 towards the return water tank 8012, so that more water in the second water tank 801 flows into the return water tank 8012, thereby increasing the water volume in the return water tank 8012. This, in turn, increases the amount of water flowing back into the water spraying tank 8011, allowing the water spraying component to continuously spray water.

[0247] In some embodiments of this disclosure, the arc-shaped plate segment 8032 is a minor arc segment. This configuration is beneficial in two ways: firstly, it improves the guiding reliability of the baffle 803 on the water in the second water tank 801; secondly, it increases the distance between the baffle 803 and the partition 802, thereby shortening the gap between the arc-shaped baffle 803 and the second side wall 805. This reduces the amount of water flowing out of the return water tank 8012 from between the baffle 803 and the second side wall 805, thus increasing the amount of water flowing into the return water tank 8012.

[0248] In some embodiments, as shown in Figures 33 and 34, a guide plate 806 is provided at one end of the baffle 803 adjacent to the partition 802. The guide plate 806 is bent and extended relative to the side of the partition 802 toward the return water tank 8012, so that the end of the guide plate 806 away from the partition 802 extends toward the open side of the arc-shaped plate segment 8032.

[0249] This configuration allows the guide plate 806 to guide the water flow between the baffle 802 and the baffle 803, allowing more water to flow towards the baffle 803 and into the return water tank 8012 under the guidance of the baffle 803. This increases the amount of water flowing into the return water tank 8012, thereby increasing the amount of water flowing back to the water spraying tank 8011 and improving the water spraying effect of the water spraying component.

[0250] It should be noted that at least a portion of the guide plate 806 and the baffle 803 are parallel to each other, so that the water flow between the guide plate 806 and the baffle 803 can be kept as stable as possible, so as to reduce the turbulence of water in the second water tank 801 and thus reduce the loss of water flowing to the return water tank 8012.

[0251] In some embodiments, as shown in FIG34, a second opening 8022 is provided at the second end of the partition 802, and the water-spraying component is adjacent to the second opening 8022 and away from the first opening 8021. In the embodiments of this disclosure, water flows from the water-spraying tank 8011 to the return water tank 8012 through the first opening 8021, and water flows from the return water tank 8012 to the water-spraying tank 8011 through the second opening 8022. Thus, by placing the water-spraying component close to the second opening 8022, the distance that water needs to flow from the return water tank 8012 to the water-spraying component can be shortened.

[0252] For example, if the second water tank 801 is short of water for a preset time, once the water in the return water tank 8012 can flow to the water pumping tank 8011, the water can flow to the water pumping component more quickly, so that the water pumping component can pump water to the outdoor heat exchanger 60 in time to dissipate heat, thereby improving the heat dissipation effect of the outdoor heat exchanger 60 and improving the heat exchange efficiency of the refrigerant in the outdoor heat exchanger 60.

[0253] For example, the water-pumping component pushes the water in the water-pumping trough 8011 to flow towards the first outlet 8021. By setting the water-pumping component away from the first outlet 8021, the direction of the water pumped by the water-pumping component can be aligned with the extension direction of the water-pumping trough 8011. This can reduce the amount of water thrown out of the second water trough 801 by the water-pumping component, allowing more water to fall into the water-pumping trough 8011 and then flow into the return water trough 8012 through the first outlet 8021.

[0254] According to an embodiment of this disclosure, the diameter of the second port 8022 is larger than the diameter of the first port 8021. This slows down the flow of water into the water tank 8011 through the second port 8022, and reduces the flow velocity of water from the second water tank 801 to the water jetting component. This arrangement helps to increase the water jetting volume of the water jetting component, improves the water jetting efficiency of the water jetting component, and allows more water to splash onto the outdoor heat exchanger 60, thereby increasing the heat dissipation efficiency of the outdoor heat exchanger 60.

[0255] In some embodiments, as shown in Figures 35 and 36, the portable air conditioner 100 further includes a water level switch 808. The water level switch 808 is disposed on a first water receiving tray 80 and is electrically connected to the compressor 30. A mounting plate 807 is disposed on the first water receiving tray 80, and the mounting plate 807 has a mounting hole 8071. At least a portion of the water level switch 808 extends into the mounting hole 8071. The mounting hole 8071 is partially open in the circumferential direction. A third limiting part 8072 is disposed on the open side of the mounting hole 8071, and the third limiting part 8072 cooperates with the water level switch 808 in a circumferential limiting manner.

[0256] For example, the water level switch 808 can detect the water level in the first water receiving tray 80. When the water level in the first water receiving tray 80 is low, the first water receiving tray 80 is closed. When the water level in the first water receiving tray 80 is higher than a preset value, the water level switch 808 is opened to drain excess water from the first water receiving tray 80, thus preventing water from overflowing and wetting the ground.

[0257] It should be noted that the water level switch 808 is electrically connected to the compressor 30, allowing the water level switch 808 to exchange control signals with the compressor 30. When the water level switch 808 detects that the water level in the first water receiving pan 80 is higher than a preset value, the water level switch 808 sends a control signal to the compressor 30 to reduce the operating efficiency of the compressor 30 or to shut down the compressor 30, thereby reducing the refrigerant flow in the portable air conditioner 100 and reducing the generation of condensate on the outdoor heat exchanger 60.

[0258] When the water level switch 808 detects that the water level in the first water receiving tray 80 is lower than the preset value, the water level switch 808 sends a control signal to the compressor 30 to keep the compressor 30 in its current working state or to work according to the user's instructions.

[0259] It should be noted that the preset value for the water level detection in the first water receiving tray 808 can be selected and set according to the model and operating conditions of the portable air conditioner 100 to meet the needs of different usage scenarios.

[0260] For example, the first water receiving tray 80 is provided with a mounting hole 8071, which is configured to install a water level switch 808. By arranging a mounting piece 807 on the first water receiving tray 80 and placing the mounting hole 8071 on the mounting piece 807, the water level switch 808 can be positioned at a designated location on the first water receiving tray 80, and the stability of the water level switch 808 in the first water receiving tray 80 can be ensured. This guarantees the accuracy of the water level switch 808 in detecting changes in the water level in the first water receiving tray 80, thereby improving the control accuracy of the portable air conditioner 100.

[0261] For example, the mounting hole 8071 is partially open in the circumferential direction, which facilitates the installation and removal of the water level switch 808 on the mounting plate 807, thereby improving the ease of installation and removal of the water level switch 808 and making it easier to inspect and replace the water level switch 808. The water level switch 808 extends at least partially into the mounting hole 8071, which ensures the installation position of the water level switch 808 in the first water receiving tray 80, thereby enabling the water level switch 808 to effectively detect changes in the water level in the first water receiving tray 80.

[0262] For example, as shown in Figures 35 and 36, a third limiting part 8072 is provided on the open side of the mounting hole 8071, and the third limiting part 8072 cooperates with the water level switch 808 in a circumferential limiting manner. In this way, after the water level switch 808 extends into the mounting hole 8071, the third limiting part 8072 can fix the water level switch 808 in the mounting hole 8071, so as to ensure the structural stability of the water level switch 808 on the mounting plate 807, and thus ensure the reliability of the water level switch 808 in detecting changes in the water level in the first water receiving tray 80.

[0263] For example, the third limiting part 8072 is circumferentially matched with the water level switch 808, which can increase the contact area between the mounting hole 8071 and the water level switch 808, thereby increasing the reliability of the water level switch 808 in the mounting hole 8071.

[0264] In some embodiments, as shown in Figures 36 and 37, the third limiting part 8072 is a limiting protrusion 244. The circumferential limiting cooperation between the third limiting part 8072 and the water level switch 808 is actually a circumferential limiting cooperation between the limiting protrusion 244 and the water level switch 808. The limiting protrusion 244 protrudes towards the center of the mounting hole 8071, which can reduce the distance from the local circumference of the mounting hole 8071 to the center of the mounting hole 8071. In this way, when the water level switch 808 is inserted into the mounting hole 8071, the water level switch 808 can be pressed towards the center of the mounting hole 8071, thereby improving the limiting reliability of the third limiting part 8072 on the water level switch 808.

[0265] For example, the limiting protrusion 244 is provided on the opposite two side walls of the corresponding open side of the mounting hole 8071. This allows the limiting protrusion 244 to press the water level switch 808 away from the open side of the mounting hole 8071, so as to prevent the water level switch 808 from disengaging from the open side of the mounting hole 8071, thereby ensuring the reliability of the water level switch 808 on the first water receiving tray 80.

[0266] For example, a nut is provided on the water level switch 808. When the water level switch 808 is inserted into the mounting hole 8071, the limiting protrusion 244 first limits the water level switch 808, and then the nut on the water level switch 808 is tightened, so that the water level switch 808 can be fixed on the mounting plate 807 of the first water receiving tray 80.

[0267] In some embodiments, as shown in FIG45, a drain hole 873 is provided on one side of the first water receiving tray 80, and the water in the first water receiving tray 80 can flow out of the first water receiving tray 80 through the drain hole 873 to drain the water at a suitable position in the first water receiving tray 80.

[0268] In some embodiments, as shown in FIG44, a clearance hole 15221 is provided on the main housing 15, which provides a stable and reliable setting position for the clearance hole 15221 and ensures the structural reliability of the clearance hole 15221. The clearance hole 15221 on the main housing 15 corresponds to the drain hole 873 on one side of the first water receiving tray 80. This allows the main housing 15 to avoid the drain hole 873 in the first water receiving tray 80, so that the water in the first water receiving tray 80 can be directly discharged to the outside of the main housing 15 through the drain hole 873.

[0269] This simplifies the drainage structure of the first water tray 80 and the drainage method of the portable air conditioner 100, enabling rapid drainage. It also helps prevent water from accumulating in the drainage pipe and causing musty odors, thus preventing the portable air conditioner 100 from producing unpleasant smells and ensuring its reliability.

[0270] Therefore, by providing a clearance hole 15221 on the outer casing 10 at the position corresponding to the drain hole 873 on the first water receiving tray 80, water in the first water receiving tray 80 can be discharged through the drain hole 873. This allows the first water receiving tray 80, which is located between the compressor 30 and the outdoor heat exchanger 60, to drain water directly through the drain hole 873, thereby simplifying the structure of the portable air conditioner 100 and facilitating its use.

[0271] In some embodiments, as shown in Figures 44 to 47, the main housing 15 includes a first front housing 151 disposed on the chassis 16. The main housing 15 also includes a first rear housing 152 disposed on the chassis 16. This allows the first front housing 151 and the first rear housing 152 to be fixed to the chassis 16, improving the structural stability of the first front housing 151 and the first rear housing 152.

[0272] For example, the first rear shell 152 includes an upper shell portion 1521. The first rear shell 152 also includes a lower shell portion 1522. The upper shell portion 1521 is connected above the lower shell portion 1522 and corresponds to the indoor heat exchanger 70, and forms a duct mounting groove 15211 (as shown in Figure 44). An air inlet pipe 43 and an air outlet pipe 44 can be installed in the duct mounting groove 15211. This not only allows outdoor air to flow through the air inlet pipe 43 and the air outlet pipe 44 through the indoor heat exchanger 70, so that the refrigerant in the indoor heat exchanger 70 can exchange heat with the outdoor air, ensuring the normal operation of the portable air conditioner 100, but also helps to improve the structural compactness of the portable air conditioner 100.

[0273] For example, the lower housing 1522 corresponds to the compressor 30, the first water tray 80, and the outdoor heat exchanger 60, respectively. This arrangement can fix and protect the compressor 30, the first water tray 80, and the outdoor heat exchanger 60. The lower housing 1522 is provided with a clearance hole 15221, which can reduce the height of the clearance hole 15221 on the main housing 15, which helps to increase the drainage potential energy of the portable air conditioner 100.

[0274] This can speed up the drainage convenience of the portable air conditioner 100 and reduce the problem of water accumulation in the portable air conditioner 100.

[0275] In some embodiments, as shown in Figures 44 and 45, the clearance hole 15221 is located in the middle of the lower housing portion 1522 in the height direction, and adjacent to one side and away from the other side in the width direction. It should be noted that, in the embodiments of this disclosure, setting the clearance hole 15221 in the middle of the lower housing portion 1522 in the height direction allows the clearance hole 15221 to be positioned at a suitable height in the height direction of the main housing 15.

[0276] This arrangement serves two purposes: firstly, it facilitates the alignment of the clearance hole 15221 with the drainage hole 873 on the first water receiving tray 80, thereby shortening the distance between the clearance hole 15221 and the drainage hole 873 and enabling rapid drainage from the first water receiving tray 80; secondly, it not only prevents the clearance hole 15221 from being too low, which would affect the normal operation of the structure in the first sub-accommodation space 141, but also prevents the clearance hole 15221 from being too high, which would affect the normal drainage of water from the first water receiving tray 80.

[0277] In some embodiments, the clearance hole 15221 is provided on one side of the main housing 15 in the width direction, and on the other side of the main housing 15 in the width direction, so that the clearance hole 15221 is located at the edge of the main housing 15. In the embodiments of this disclosure, the clearance hole 15221 is on the side of the main housing 15 near the compressor 30. In this way, the space above the compressor 30 in the accommodating space 14 can be fully utilized, which is beneficial to improving the space utilization rate inside the portable air conditioner 100.

[0278] In some embodiments, as shown in Figures 45 and 46, the portable air conditioner 100 further includes a drain pipe connector 874, which can be connected to a drain pipe. In embodiments of this disclosure, the drain pipe connector 874 can communicate with a drain hole 873 to lead water from the first water receiving tray 80 out of the portable air conditioner 100. This arrangement avoids pipe bending within the portable air conditioner 100, avoids occupying internal space of the portable air conditioner 100, and avoids affecting the operation of other structures, thereby improving the reliability of the portable air conditioner 100.

[0279] For example, as shown in Figure 46, a drain flange 8731 is provided on the first water receiving tray 80. The drain flange 8731 has a clearance hole 15221, which allows the drain flange 8731 to extend outwards from the main housing 15. The drain hole 873 is connected to the drain flange 8731 to guide water through the drain flange 8731 to the outside of the main housing 15. The drain flange 8731 extends into the drain pipe connector 874, which facilitates the connection between the drain flange 8731 and the drain pipe connector 874. The connection between the drain flange 8731 and the drain pipe connector 874 allows water in the first water receiving tray 80 to be guided into the drain pipe through the drain flange 8731 and the drain pipe, and then discharged from the portable air conditioner 100 through the drain pipe.

[0280] Thus, by connecting the drain pipe connector 874 and the drain flange 8731, the drain pipe can be connected to the outside of the main housing 15 of the portable air conditioner 100. This reduces the number of parts in the portable air conditioner 100, simplifies the structure of the portable air conditioner 100, and improves the space utilization inside the portable air conditioner 100.

[0281] In some embodiments, as shown in Figures 46 and 47, the outer periphery of the drain flange 8731 is provided with an external thread 8732, and the inner wall of the drain pipe connector 874 is provided with an internal thread 8741. The external thread 8732 and the internal thread 8741 are threadedly connected. For example, the drain pipe connector 874 and the drain flange 8731 are connected by threads, which simplifies the connection method of the drain pipe connector 874 and the drain flange 8731, and makes the drain pipe connector 874 and the drain flange 8731 detachable.

[0282] For example, when the portable air conditioner 100 needs to drain, the drain pipe can be connected to the drain flange 8731 via the drain pipe connector 874 to allow the first drip tray 80 to drain. When the portable air conditioner 100 does not need to drain, the drain pipe connector 874 can be removed from the drain flange 8731 to facilitate the movement and use of the portable air conditioner 100.

[0283] It should be noted that the outer periphery of the drain flange 8731 is provided with an external thread 8732, and the inner wall of the drain pipe connector 874 is provided with an internal thread 8741. The external thread 8732 and the internal thread 8741 are threadedly connected. This allows the drain pipe connector 874 to be located outside the drain flange 8731, thereby improving the sealing between the drain pipe connector 874 and the drain flange 8731 and preventing water leakage from the portable air conditioner 100 during the drainage process.

[0284] In some embodiments, as shown in FIG46, a gasket 875 is provided between the drain pipe connector 874 and the drain flange 8731. When the drain pipe connector 874 and the drain flange 8731 are threadedly connected by the external thread 8732 and the internal thread 8741, the gasket 875 can prevent the drain pipe connector 874 and the drain flange 8731 from loosening, and can ensure the reliability of the connection between the drain pipe connector 874 and the drain flange 8731.

[0285] For example, during the drainage process of the portable air conditioner 100, the gasket 875 can, on the one hand, reduce the vibration and impact on the drain pipe joint 874 and the drain flange 8731, thus protecting them. On the other hand, the gasket 875 can improve the sealing performance between the drain pipe joint 874 and the drain flange 8731, helping to prevent water leakage at the connection point and thereby improving the drainage reliability of the portable air conditioner 100.

[0286] In some embodiments, as shown in FIG47, the drain flange 8731 is multi-ringed. The multi-ringed drain flange 8731 is concentrically arranged so that the multi-ringed drain flange 8731 corresponds to the drain hole 873 on the first water receiving tray 80, so that the water in the first water receiving tray 80 is discharged through the drain hole 873. This simplifies the structure of the portable air conditioner 100 and improves the space utilization efficiency of the portable air conditioner 100.

[0287] It should be noted that the multiple drainage flanges 8731 are radially spaced, which not only facilitates the concentric arrangement of the multiple drainage flanges 8731, but also allows the multiple drainage flanges 8731 to have different radial dimensions. This makes the multiple drainage flanges 8731 suitable for connecting with drainage pipes of different diameters, and allows drainage pipes of different diameters to connect with the same drainage hole 873, thereby increasing the applicability of the drainage hole 873 and improving the ease of use of the portable air conditioner 100.

[0288] According to embodiments of this disclosure, as shown in Figures 47 and 48, the drainage flange 8731 consists of two rings, namely a first drainage flange 8733 and a second drainage flange 8735. For example, the second drainage flange 8735 is concentrically arranged with the first drainage flange 8733, which facilitates the provision of two drainage flanges 8731 at the position of a drainage hole 873 on the first water receiving tray 80, thereby increasing the applicability of the drainage hole 873.

[0289] For example, the second drainage flange 8735 is radially spaced on the outer periphery of the first drainage flange 8733, which can make the radial dimension of the second drainage flange 8735 larger than the radial dimension of the first drainage flange 8733, and the first drainage flange 8733 corresponds to the drainage hole 873.

[0290] When the drain pipe orifice is small, the orifice of the drain pipe connector 874 is also small, allowing the smaller-diameter drain pipe connector 874 to connect to the first drain flange 8733, ensuring reliable connection and sealing between the drain pipe connector 874 and the first drain flange 8733. At this time, water in the first water tray 80 can flow into the drain pipe through the drain hole 873, the first drain flange 8733, and the drain pipe connector 874, and then be discharged from the portable air conditioner 100.

[0291] When the drain pipe has a larger orifice, the drain pipe connector 874 can also have a larger orifice, allowing the larger-diameter drain pipe connector 874 to connect to the second drain flange 8735, ensuring reliable connection and sealing between the drain pipe connector 874 and the second drain flange 8735. Since the second drain flange 8735 is concentrically positioned with the first drain flange 8733, water in the first water tray 80 can flow into the drain pipe through the drain hole 873, the first drain flange 8733, and the drain pipe connector 874, and then be discharged from the portable air conditioner 100.

[0292] In the embodiments of this disclosure, the number of drainage flanges 8731 can be set according to the usage requirements of the product. Each drainage flange 8731 is radially arranged with other drainage flanges 8731, and the radial dimension of each drainage flange 8731 can be set according to the diameter of the drain pipe.

[0293] It should be noted that among all the drainage flanges 8731, the drainage flange 8731 with the smallest radial dimension is connected to the drainage hole 873 of the first water receiving plate 80.

[0294] In some embodiments, as shown in FIG45, a drainage groove 8734 is provided on the first water receiving tray 80. The drainage groove 8734 is recessed downward relative to the first water receiving tray 80. This allows the water in the first water receiving tray 80 to generate a potential energy difference between other positions in the first water receiving tray 80 and the drainage groove 8734, thereby causing the water in other positions in the first water receiving tray 80 to gather in the drainage groove 8734, so that the water in the first water receiving tray 80 can flow to the drainage hole 873 and finally be discharged from the first water receiving tray 80 through the drainage hole 873. This configuration can improve the drainage reliability of the first water receiving tray 80.

[0295] In some embodiments, the drain hole 873 is located on one side of the drain trough 8734. Thus, when water from other locations in the first water receiving tray 80 flows into the drain trough 8734 and accumulates in it, the water in the drain trough 8734 can flow into the drain hole 873. The drain hole 873 is connected to the drain trough 8734, allowing water in the drain trough 8734 to be discharged directly through the drain hole 873. This improves the drainage convenience of the drain trough 8734 and prevents water from stagnating in the drain trough 8734 and causing a musty odor.

[0296] In some embodiments, as shown in Figures 28 and 29, the portable air conditioner 100 further includes a second water tray 88, which is disposed above the outdoor heat exchanger 60 and below the indoor heat exchanger 70. This allows the structural components of the portable air conditioner 100 to be arranged compactly in the accommodating space 14, which is beneficial to improving the structural compactness of the portable air conditioner 100 and thus reducing the size of the portable air conditioner 100, thereby improving the portability of the portable air conditioner 100.

[0297] When the refrigerant absorbs heat and evaporates in the indoor heat exchanger 70, the surface temperature of the indoor heat exchanger 70 decreases. Water vapor in the air condenses into water upon contact with the condenser and then falls into the second water collection tray 88 at the bottom of the indoor heat exchanger 70. The water then flows out through the drain hole 873 on the second water collection tray 88. This prevents the condensate from dripping onto the ground and causing the portable air conditioner 100 to slip.

[0298] In some embodiments, as shown in FIG28, the second water receiving tray 88 is provided with at least one water outlet, and the outdoor heat exchanger 60 is provided with a water flow channel 63. The water outlet is connected to the first water receiving tray 80 through the water flow channel 63. In this way, the water accumulated in the second water receiving tray 88 can flow out of the second water receiving tray 88 through the water outlet, and then flow into the water flow channel 63 between the outdoor heat exchangers 60. Then, it flows into the first water receiving tray 80 along with the condensate on the outdoor heat exchanger 60. Finally, it is discharged from the portable air conditioner 100 through the drain hole 873 of the first water receiving tray 80. This helps to improve the drainage reliability of the first water receiving tray 80 and the second water receiving tray 88 in the portable air conditioner 100.

[0299] According to some embodiments of this disclosure, as shown in Figures 28 and 29, the second water receiving tray 88 is disposed above the outdoor heat exchanger 60 and the outdoor air duct assembly 20, and the indoor heat exchanger 70 and the indoor air duct assembly 40 are disposed above the second water receiving tray 88. This not only isolates the outdoor heat exchanger 60 and the indoor heat exchanger 70, but also isolates the outdoor air duct assembly 20 and the indoor air duct assembly 40. Thus, the compressor 30 and the electrical control box 50 are located at the bottom layer, the outdoor heat exchanger 60 and the outdoor air duct assembly 20 are located at the second layer, and the indoor heat exchanger 70 and the indoor air duct assembly 40 are located at the third layer, thereby forming a three-layer structure.

[0300] Furthermore, the second water tray 88 also serves to store water, allowing the condensate produced by the indoor heat exchanger 70 to flow to the second water tray 88. This prevents the condensate produced by the indoor heat exchanger 70 from overflowing and also prevents the condensate produced by the indoor heat exchanger 70 from affecting the safety of the internal circuit of the portable air conditioner 100, thus avoiding short circuits. The water in the second water tray 88 can flow downwards to the first water tray 80 through the water holes.

[0301] In some embodiments, as shown in Figures 29 and 30, a second water receiving tray 88 is disposed in the receiving space 14 and connected to the outer casing 10. An indoor heat exchanger 70 is disposed above the second water receiving tray 88, which is provided with a first water tank 89 and at least one water outlet, the first water tank 89 and at least one water outlet being connected.

[0302] It should be noted that at least one outlet includes multiple outlets, and the first water tank 89 is connected to multiple outlets.

[0303] For example, condensate will condense on the surface of the indoor heat exchanger 70 during heat exchange. The second water collection tray 88 is located below the indoor heat exchanger 70. The condensate will flow into the first water tank 89 of the second water collection tray 88 under the action of gravity. The outlet includes a first water outlet 891. The condensate flows out through the outlet end of the first water tank 89 to the first water outlet 891, and finally flows out to the outside from the first water outlet 891, thereby realizing the discharge of condensate from the second water collection tray 88.

[0304] For example, as shown in Figures 29 and 30, the outlets of the first water outlet 891 and the first water tank 89 are spaced apart, and multiple water guide ribs 892 are provided between the outlets of the first water outlet 891 and the first water tank 89. A water guide channel 893 is formed between two adjacent water guide ribs 892. There are multiple outlets 891 and multiple water guide channels 893. The inlet of the multiple water guide channels 893 is connected to the outlet of the first water tank 89, and the outlet of the multiple water guide channels 893 is connected to the multiple outlets 891.

[0305] For example, by setting the water outlets of the first water outlet 891 and the first water tank 89 at intervals, and by setting a plurality of water guide ribs 892 between the water outlets of the first water outlet 891 and the water tank 89, a water guide channel 893 is defined between two adjacent water guide ribs 892, and there are a plurality of water guide channels 893.

[0306] By connecting multiple water guiding channels 893 and multiple first water outlets 891, condensate can flow from the outlet of the first water tank 89 into the multiple water guiding channels 893, and then through the multiple water guiding channels 893 into the multiple first water outlets 891, thus allowing the condensate to flow out from the multiple first water outlets 891. This configuration increases the water output of the second water receiving tray 88 per unit time through the multiple first water outlets 891, and improves the smoothness of condensate flow through the multiple water guiding channels 893, thereby enhancing the water output efficiency of the second water receiving tray 88.

[0307] In some embodiments, as shown in Figures 29 and 30, a water guiding slope 894 is provided between the first water outlet 891 and the water outlet end of the first water tank 89, and a plurality of water guiding ribs 892 are provided on the water guiding slope 894. The water guiding slope 894 is inclined from top to bottom, and the first water outlet 891 is provided at the lower end of the water guiding slope 894.

[0308] For example, by setting a water-guiding slope 894 between the first outlet 891 and the outlet end of the first water tank 89, and by placing multiple water-guiding ribs 892 within the water-guiding slope 894, the water-guiding slope 894 is inclined in a downward direction. After the condensate flows from the outlet end of the first water tank 89 into the water-guiding channel 893, the water flow will continuously accelerate under the action of gravity due to the inclined setting of the water-guiding slope 894. This increases the speed of the water flow in the water-guiding channel 893, allowing it to flow quickly to the first outlet 891 and exit from it, thus improving the water discharge efficiency of the second water receiving tray 88.

[0309] In some embodiments, as shown in Figures 29 and 30, the water outlet further includes a second water outlet 895, which is spaced apart on the outside of the plurality of water guide ribs 892.

[0310] For example, by providing a second outlet 895 on the second water receiving tray 88, if the water flow from the water guiding channel 893 to the first outlet 891 is excessive and the first outlet 891 cannot discharge the water in time, the water will overflow to the outside of the multiple water guiding ribs 892. This will then enter the second outlet 895 and flow out from it. This improves the reliability of drainage from the second water receiving tray 88 and optimizes its structural design.

[0311] For example, the second water receiving tray 88 contains a first water trough 89, a water guiding slope 894 is located on one side of the first water trough 89, a first water outlet 891 is located at the bottom of the first water trough 89, and a second water outlet 895 is also located at the bottom of the first water trough 89. Multiple water guiding ribs 892 are arranged on the water guiding slope 894. When excessive water flows into the first water trough 89 through the water guiding slope 894, and the first water outlet 891 cannot discharge it in time, the water level will exceed the height of the multiple water guiding ribs 892, causing water to overflow from the multiple water guiding ribs 892 and flow towards the second water outlet 895, which is also located at the bottom of the first water trough 89, and then flow out from the second water outlet 895.

[0312] In some embodiments, as shown in Figures 29 and 30, the diameter of the second outlet 895 is larger than the diameter of the first outlet 891.

[0313] For example, there can be one second outlet 895, and the diameter of the second outlet 895 can be set to be larger than the diameter of the single first outlet 891. This can improve the water discharge efficiency of the second outlet 895, thereby improving the water discharge efficiency of the second water receiving tray 88, while facilitating the manufacture of the second water receiving tray 88.

[0314] In some embodiments, as shown in FIG28, the outdoor heat exchanger 60 is located below the second water receiving tray 88, and the first water receiving tray 80 is located below the outdoor heat exchanger 60. The water pumping device 87 includes a water pumping component and a water pumping drive component 872. The water pumping component is rotatably disposed on the first water receiving tray 80, and the water pumping drive component 872 is disposed on the first water receiving tray 80 and is drivenly connected to the water pumping component. The water pumping component can be a water pumping wheel 871.

[0315] In some embodiments, the outdoor heat exchanger 60 includes a first heat exchange element 61. The outdoor heat exchanger 60 also includes a second heat exchange element 62. The first heat exchange element 61 and the second heat exchange element 62 are spaced apart to form a water flow channel 63, and a water impeller 871 is correspondingly disposed at the lower end of the water flow channel 63.

[0316] For example, by setting a first water collection tray 80 below the outdoor heat exchanger 60, condensation will be generated on the surface of the outdoor heat exchanger 60 during heat exchange. This condensation will flow to the first water collection tray 80 under gravity. By setting a water-spraying wheel 871 and a water-spraying drive 872 on the first water collection tray 80, and by having the water-spraying drive 872 drive the water-spraying wheel 871 to rotate, the rotation of the water-spraying wheel 871 can splash water from the first water collection tray 80, thus cooling the surface of the indoor heat exchanger 70. In this way, the water in the first water collection tray 80 can be self-treated, and the heat exchange efficiency of the indoor heat exchanger 70 can also be improved.

[0317] For example, by arranging the first heat exchanger 61 and the second heat exchanger 62 alternately, a water flow channel 63 is formed. Water on the outdoor heat exchanger 60 can flow through the water flow channel 63 to the water impeller 871, and water on the second water receiving tray 88, after flowing out of the first outlet 891, can also flow through the water flow channel 63 to the water impeller 871. This not only ensures the smooth flow of water from the outdoor heat exchanger 60 to the first water receiving tray 80, but also ensures the smooth flow of water from the second water receiving tray 88 to the first water receiving tray 80.

[0318] It should be noted that when the outdoor heat exchanger 60 is a condenser, the first heat exchange element 61 is a single-row condenser and the second heat exchange element 62 is a triple-row condenser. This ensures the heat exchange efficiency of the outdoor heat exchanger 60 while ensuring the smooth flow of water through the water channel 63.

[0319] In some embodiments, as shown in Figures 31 and 32, the portable air conditioner 100 further includes a sealing plate 94, which covers the upper side of the outdoor heat exchanger 60. The sealing plate 94 is provided with a guide groove 95, which is correspondingly connected to the water flow channel 63.

[0320] It should be noted that the sealing plate 94 is placed on the upper side of the outdoor heat exchanger 60, and a guide groove 95 is provided on the sealing plate 94, corresponding to the water flow channel 63. The sealing plate 94, together with the second water receiving tray 88, serves two purposes: firstly, it protects the upper part of the outdoor heat exchanger 60; secondly, because the sealing plate 94 is close to the outdoor heat exchanger 60, condensate will condense on its surface. Therefore, the guide groove 95 on the sealing plate 94 allows the condensate to flow towards the water flow channel 63 under the guidance of gravity and the guide groove 95. This allows the condensate to flow through the water flow channel 63 to the first water receiving tray 80, thus improving the drainage performance of the condensate on the sealing plate 94.

[0321] In some implementations, as shown in Figures 31 and 32, the cross-section of the guide channel 95 in the vertical direction is set to an inverted V shape, increasing the horizontal cross-sectional area of ​​the guide channel 95 from top to bottom. This makes the guidance of condensate by the guide channel 95 more stable and smooth, and makes the flow of condensate to the water flow channel 63 more uniform, thus improving the guiding effect of the guide channel 95 and facilitating the discharge of condensate from the sealing plate 94.

[0322] In some embodiments, as shown in Figures 31 and 32, the inner wall of the guide channel 95 is provided with a plurality of guide ribs 96, and a guide channel 97 is formed between two adjacent guide ribs 96. There are multiple guide channels 97, and the multiple guide channels 97 are correspondingly connected to the water flow channel 63.

[0323] For example, by setting multiple guide ribs 96 in the guide channel 95 and forming a guide channel 97 between two adjacent guide ribs 96, not only can the guiding stability of the guide channel 95 for condensate be improved, but the structure of the guide channel 95 can also be simplified.

[0324] In some embodiments, the sealing plate 94 and the second water receiving tray 88 are configured as an integrally formed structural component, which not only simplifies the installation steps of the sealing plate 94 and the second water receiving tray 88 in the receiving space 14, but also improves the stability of the connection between the sealing plate 94 and the second water receiving tray 88, thereby improving the structural reliability of the portable air conditioner 100.

[0325] In some embodiments, the sealing plate 94 and the second water receiving tray 88 are detachably connected, which allows for convenient individual maintenance and replacement of the sealing plate 94 and the second water receiving tray 88 while ensuring the stable connection between them.

[0326] According to some embodiments of this disclosure, the outdoor heat exchanger 60 and the outdoor air duct assembly 20 are arranged in a first horizontal direction, and the indoor heat exchanger 70 and the indoor air duct assembly 40 are arranged in a second horizontal direction, with the first horizontal direction and the second horizontal direction being perpendicular.

[0327] For example, as shown in Figures 27 and 64, the outdoor heat exchanger 60 and the outdoor air duct assembly 20 are arranged in a first horizontal direction, which is a horizontal arrangement in the left-right direction of the portable air conditioner 100. The indoor heat exchanger 70 and the indoor air duct assembly 40 are arranged in a second horizontal direction, which is a horizontal arrangement in the front-back direction of the portable air conditioner 100. In this way, the first and second horizontal directions are perpendicular, which can balance the forces inside the portable air conditioner 100, making the forces inside the portable air conditioner 100 more uniform and thus improving the stability of the portable air conditioner 100. When the portable air conditioner 100 is working, it can also reduce the noise generated by the portable air conditioner 100, thereby improving comfort.

[0328] In some embodiments, as shown in Figures 2, 3, and 27, the housing 10 includes an air inlet 11. The air inlet 11 corresponds to the indoor heat exchanger 70. The housing 10 also includes an air outlet 12, which corresponds to the outlet 532 of the indoor air duct assembly 40 (as shown in Figure 22) and extends vertically.

[0329] It should be noted that the air inlet 11 corresponds to the indoor heat exchanger 70, which can increase the contact area between the air inlet 11 and the indoor heat exchanger 70, thereby improving the heat exchange efficiency of the indoor heat exchanger 70, that is, improving the heat exchange efficiency of the evaporator.

[0330] Furthermore, the air outlet 12 corresponds to the outlet 532 of the indoor air duct assembly 40, which can accelerate the heat exchange speed of the indoor heat exchanger 70, thereby improving the heat exchange efficiency of the portable air conditioner 100.

[0331] It should be noted that the air outlet 12 extends in the vertical direction, so that the air outlet 12 can form a vertical air outlet, which means air outlet in the vertical direction. This can increase the range of vertical air supply and expand the air supply area, thereby increasing the air supply volume of the portable air conditioner 100.

[0332] In some embodiments, as shown in FIG2, the indoor air duct assembly 40 further includes an indoor fan 42, which is disposed within the indoor air duct component 41. The indoor fan 42 is a cross-flow fan that extends in the vertical direction.

[0333] In some embodiments, the indoor air duct component 41 is disposed on one side of the indoor heat exchanger 70. The indoor air duct component 41 can form an air duct, which can facilitate air outlet and also provide installation space for the indoor fan 42.

[0334] It should be noted that the indoor fan 42 can be a cross-flow fan. The axial length of the cross-flow fan is not limited, and the impeller length can be selected according to different usage needs. Moreover, the airflow flows through the impeller and is subjected to the force of the blades twice, so the airflow is transmitted over a long distance. In addition, the cross-flow fan has no turbulence and the air outlet is uniform, which can improve the comfort of the air outlet.

[0335] For example, cross-flow fans extend vertically, creating vertical airflow and thus increasing the vertical air volume.

[0336] According to some embodiments of this disclosure, as shown in Figures 1, 13, and 14, the portable air conditioner 100 further includes a plurality of air guide vanes 90. The air guide vanes 90 extend vertically and are arranged horizontally. This arrangement allows for adjustment of their direction and angle to adapt to different needs. Users can adjust the air guide vanes 90 according to actual needs or the layout of the indoor space to obtain a more suitable airflow effect.

[0337] In addition, multiple air deflectors 90 help to diffuse the airflow and reduce the feeling of direct wind blowing on the human body. This uniform airflow distribution is more in line with human comfort, thus avoiding discomfort caused by excessive wind speed.

[0338] For example, the vertical extension and horizontal arrangement of multiple air deflectors 90 can help the portable air conditioner 100 distribute air more evenly, avoiding uneven heating and cooling, thereby providing a more comfortable indoor temperature.

[0339] According to some embodiments of this disclosure, as shown in Figures 3 to 6, a second water receiving tray 88 is disposed above the outdoor heat exchanger 60 and the outdoor air duct assembly 20, and an indoor heat exchanger 70 and an indoor air duct assembly 40 are disposed above the second water receiving tray 88. The air guide plate 90 has an upper rotating shaft 91 and a lower rotating hole 822. The upper end of the air duct component is provided with an upper rotating hole 411 (as shown in Figure 11). The second water receiving tray 88 is provided with a mounting boss 821. The mounting boss 821 (as shown in Figure 12) is provided with a lower rotating shaft 92. The upper rotating shaft 91 is rotatably disposed in the upper rotating hole 411, and the lower rotating shaft 92 is rotatably disposed in the lower rotating hole 822.

[0340] For example, the lower end of the air guide plate 90 is provided with a lower rotating hole 822, so that the lower rotating shaft 92 of the mounting boss 821 extends into the lower rotating hole 822 at the lower end of the air guide plate 90, thereby allowing the lower end of the air guide plate 90 to rotate around the lower rotating shaft 92.

[0341] In some embodiments, the portable air conditioner 100 further includes an electrical component 52, which is electrically connected to the compressor 30, the outdoor air duct assembly 20, and the indoor air duct assembly 40 respectively. The electrical component 52 includes an electrical control box 50. Thus, the electrical control box 50 is electrically connected to the compressor 30, the outdoor air duct assembly 20, and the indoor air duct assembly 40 respectively, so that the electrical component 52 can control the circuit switching of the compressor 30, the outdoor air duct assembly 20, and the indoor air duct assembly 40 respectively, thereby ensuring the normal operation of the portable air conditioner 100.

[0342] For example, within the housing space 14, the compressor 30 and the electrical components 52 are spaced apart in the horizontal direction of the housing space 14, thereby preventing interference between the compressor 30 and the electrical components 52.

[0343] In some embodiments, the outdoor heat exchanger 60, indoor heat exchanger 70, outdoor air duct assembly 20, and indoor air duct assembly 40 are disposed above the compressor 30 and electrical components 52. In this way, by making reasonable use of the internal space of the portable air conditioner 100, the compressor 30 and electrical components 52 are separated from the outdoor heat exchanger 60, indoor heat exchanger 70, outdoor air duct assembly 20, and indoor air duct assembly 40, respectively, forming an independent module. This not only facilitates maintenance and replacement but also improves the heat exchange efficiency of the portable air conditioner 100.

[0344] It should be noted that a heat dissipation vent 19 is provided at the bottom of the outer casing 10. The heat dissipation vent 19 is connected to the interior of the electrical component 52. The inlet 531 of the outdoor air duct assembly 20 is located on the side of the compressor 30 away from the electrical component 52. The air entering the electrical component 52 from the heat dissipation vent 19 flows from around the compressor 30 to the inlet 531 of the outdoor air duct assembly 20.

[0345] For example, the bottom of the housing 10 is provided with a heat dissipation vent 19, which is correspondingly set with the electrical component 52. This allows air to directly enter the electrical component 52 from the heat dissipation vent 19 to dissipate heat, thereby preventing the electrical component 52 from overheating and avoiding damage to the electrical component 52.

[0346] In some embodiments, the bottom of the housing 10 is provided with a plurality of heat dissipation vents 19, which are evenly spaced apart. This not only speeds up the air intake speed of the heat dissipation vents 19, but also makes the air output of the heat dissipation vents 19 more uniform.

[0347] For example, the air entering the electrical device 52 from the heat dissipation vent 19 flows from around the compressor 30 to the inlet 531 of the outdoor air duct assembly 20. This increases the contact area between the air intake of the heat dissipation vent 19 and the compressor 30 and the outdoor air duct assembly 20, thereby expanding the heat dissipation range and improving the heat dissipation efficiency.

[0348] For example, the air inlet duct 43 and the air outlet duct 44 are located behind the indoor heat exchanger 70, which not only makes reasonable use of the space of the portable air conditioner 100, but also improves the heat exchange efficiency of the indoor heat exchanger 70.

[0349] For example, as shown in Figure 20, a heat sink is provided in the lower part of the electrical control box 50, and the heat sink 19 includes a first heat sink 191, with the heat sink and the first heat sink 191 being arranged opposite each other.

[0350] It should be noted that a heat sink is installed in the lower part of the electrical control box 50, which can accelerate the airflow and thus improve the heat dissipation speed. Furthermore, the design of the first heat dissipation vent 191 facilitates airflow and increases the air intake volume.

[0351] Furthermore, the radiator is positioned opposite to the first heat dissipation vent 191, allowing the air entering through the first heat dissipation vent 191 to directly act on the radiator. This increases the radiator's contact area with the air, thereby improving the radiator's heat dissipation speed and efficiency.

[0352] According to some embodiments of this disclosure, as shown in Figures 23 and 24, the electrical component 52 further includes a reactor 53, which is disposed on one side of the electrical control box 50. The heat dissipation vent 19 includes a second heat dissipation vent 192 (as shown in Figure 21), and the reactor 53 has an inlet 531 located at the bottom of the reactor 53, which is disposed opposite to the second heat dissipation vent 192.

[0353] The reactor 53 is located on one side of the electrical control box 50. The reactor 53 can suppress surges or harmonic currents. Furthermore, the second heat dissipation vent 192 allows for easy connection between the second heat dissipation vent 192 and the inlet 531 of the reactor 53. This not only guides airflow but also forms an air intake duct, thereby accelerating the speed at which air enters the reactor 53 through the inlet 531 and increasing the airflow volume.

[0354] According to some embodiments of this disclosure, as shown in Figures 23 and 26, the support plate 81 is provided with a first vent, which is located on one side of the radiator. The support plate 81 is also provided with a second vent, which is connected to the outlet 532 of the reactor 53.

[0355] For example, a first vent is provided below the support plate 81, which facilitates the inflow or outflow of air, thereby increasing the air intake or exhaust range. Moreover, the first vent is located on one side of the radiator, which can increase the contact between the air intake of the first vent and the radiator, thereby improving the heat dissipation efficiency of the radiator.

[0356] According to some embodiments of this disclosure, a ventilation grille is provided at the first ventilation opening.

[0357] For example, a ventilation grille is provided at the first ventilation opening, which makes it easy to adjust the direction and angle of the airflow from the first ventilation opening, so as to meet the different scenarios and needs of the portable air conditioner 100.

[0358] For example, an electric damper can be installed at the first ventilation opening. The rotation direction and opening / closing angle of the electric damper can be controlled by a motor, thereby improving ventilation efficiency.

[0359] According to some embodiments of this disclosure, as shown in FIG25, the reactor 53 includes a protective cover 54, the bottom of the protective cover 54 is provided with an inlet 531, and the top of the protective cover 54 is provided with an outlet 532. The support plate 81 is provided with a guide shroud 85 at the position corresponding to the second ventilation opening. The guide shroud 85 is located above the outlet 532 and is connected to the outlet 532.

[0360] It should be noted that the protective cover 54 serves to protect the reactor 53, thereby preventing damage to the reactor 53. The bottom of the protective cover 54 is provided with an inlet 531, so that the air intake of the heat dissipation vent 19 can enter from the inlet 531 at the bottom of the protective cover 54, thereby improving the heat dissipation efficiency of the reactor 53.

[0361] For example, the top of the protective cover 54 is provided with an outlet 532, so that after the reactor 53 has completed heat exchange, the absorbed heat can be sent out from the outlet 532 at the top of the protective cover 54, thereby reducing the temperature around the reactor 53.

[0362] Furthermore, one end of the flow guide 85 is connected to the outlet 532 at the top of the protective cover 54, and the other end of the flow guide 85 is connected to the second vent corresponding to the support plate 81. In this way, the air after heat exchange in the reactor 53 flows through the flow guide 85 to the second vent, which facilitates air outlet and realizes heat exchange circulation, thereby improving the heat exchange efficiency of the reactor 53.

[0363] In some embodiments, as shown in FIG40, a power cord 101 is led out from the electrical control box 50. The power cord 101 is configured to connect to a power source, thereby supplying power to the portable air conditioner 100 so that the portable air conditioner 100 can operate normally. The chassis 16 is provided with a power cord outlet 163. The electrical control box 50 and the power cord outlet 163 are spaced apart to ensure that the power cord outlet 163 is not obstructed and that the power cord 101 extends from the power cord outlet 163 for connecting to an external power source. In the wiring layout within the portable air conditioner 100, the power cord 101 extends from the electrical control box 50 and extends toward the power cord outlet 163, and then extends out of the portable air conditioner 100 through the power cord outlet 163.

[0364] In some embodiments, as shown in Figures 40 and 41, a limiting part 8121 is provided on the support plate 81. When the power cord 101 extends out from the control box 50, it can pass through the limiting part 8121 and then extend to the power cord outlet 163. In this way, the limiting part 8121 can fix the power cord 101 on the support plate 81, so as to play a role in binding and guiding the power cord 101 in the portable air conditioner 100. This not only allows the power cord 101 to be led to the power cord outlet 163, but also makes the power cord 101 neatly routed in the portable air conditioner 100, making the wiring in the portable air conditioner 100 simpler.

[0365] In some embodiments, as shown in Figures 41 to 43, the mainboard 811 is disposed between the control box 50 and the compressor 30, which helps to increase the structural stability of the control box 50 and the compressor 30 on the chassis 16, and can reduce the shaking of the control box 50 and the compressor 30 during the movement of the portable air conditioner 100, thereby ensuring the reliability of the portable air conditioner 100.

[0366] For example, the first side plate 812 is disposed on the side of the main board 811 adjacent to the power cord outlet 163, and the first side plate 812 is bent relative to the main board 811. The limiting part 8121 is disposed on the first side plate 812. With this arrangement, on the one hand, when the power cord 101 passes through the limiting part 8121, the power cord 101 can be guided to the power cord outlet 163, which can ensure that the power cord 101 extends in the direction of the power cord outlet 163. This can prevent the power cord 101 from getting tangled in the portable air conditioner 100 and can shorten the distance from the power cord 101 to the power cord outlet 163 as much as possible.

[0367] This helps to shorten the length of the power cord 101, which not only saves on the production cost of the portable air conditioner 100, but also simplifies the wiring inside the portable air conditioner 100, thereby improving the wiring layout inside the portable air conditioner 100.

[0368] On the other hand, the bending of the first side plate 812 relative to the main plate 811 not only increases the support area of ​​the support plate 81 and the bottom of the first water receiving tray 80, preventing the first water receiving tray 80 from tilting relative to the horizontal plane, thereby improving the structural stability of the first water receiving tray 80 and effectively preventing water from spilling out of the first water receiving tray 80, but also allows the main plate 811 and the first side plate 812 to surround the compressor 30 to prevent the compressor 30 from shaking, which helps to ensure the safety of the compressor 30 during the movement of the portable air conditioner 100.

[0369] In some embodiments, as shown in Figures 40, 41, 42, and 43, the limiting portion 8121 includes a first limiting portion 81211. The limiting portion 8121 also includes a second limiting portion 81212. The first limiting portion 81211 and the second limiting portion 81212 are spaced apart from each other on the first side plate 812. The second limiting portion 81212 is located on the side of the first limiting portion 81211 facing the power cord outlet 163 and is lower than the first limiting portion 81211. The power cord 101 passes through the first limiting portion 81211 and the second limiting portion 81212 in sequence and extends out from the power cord outlet 163.

[0370] For example, a first limiting part 81211 and a second limiting part 81212 are sequentially arranged on the first side plate 812 in the direction from the control box 50 toward the power cord outlet 163, so that the power cord 101 can be guided toward the power cord outlet 163.

[0371] Compared to the first limiting part 81211, the second limiting part 81212 is set on the side closer to the power cord outlet 163 in the horizontal direction, and is set lower than the first limiting part 81211 in the vertical direction. This setting not only allows the first limiting part 81211 to be set close to the position where the power cord 101 extends from the control box 50, which can ensure the stability of the end of the power cord 101 connected to the control box 50, but also guides the power cord 101 to the power cord outlet 163 through the second limiting part 81212, so that the power cord 101 is routed in the direction of the power cord outlet 163, thereby ensuring the accuracy of the routing of the power cord 101 and optimizing the arrangement of the power cord 101 in the portable air conditioner 100.

[0372] In addition, the first limiting part 81211 and the second limiting part 81212 can fix the power cord 101, preventing it from shaking in the portable air conditioner 100 and ensuring that the power cord 101 is stably mounted on the support plate 81 after extending from the control box 50. If the power cord 101 shakes in the portable air conditioner 100, it may be dragged by other components and disconnected from the external power supply. This design improves the reliability of the connection between the power cord 101 and the external power supply.

[0373] In some embodiments, as shown in Figures 40 and 41, the electrical control box 50 has a cable outlet on the side adjacent to the first side plate 812, and a cable bundle 552 is provided at the cable outlet. The cable bundle 552 is spaced apart from the first limiting part 81211 and is located at the same height.

[0374] For example, by providing a cable outlet on the control box 50, the power cord 101 can extend out of the control box 50, allowing the power cord 101 to extend out of the portable air conditioner 100 and connect to an external power source.

[0375] For example, a cable tie 552 is also provided at the outlet of the control box 50. Since the power cord 101 bends when it extends out of the control box 50, and the bend extends away from the control box 50, it will take up more space in the portable air conditioner 100. Therefore, by providing a cable tie 552 at the outlet, the power cord 101 can be brought closer to the control box 50 after it extends out of the control box 50, so that the power cord 101 can be kept close to the surface of the control box 50.

[0376] For example, by setting the cable harness 552 and the first limiting part 81211 at a distance and at the same height, the power cord 101 can be routed directly to the first limiting part 81211 after extending from the outlet, which can shorten the length of the power cord 101 between the outlet and the first limiting part 81211 and prevent the power cord 101 from getting tangled. It can also prevent the cable harness 552 and the first limiting part 81211 from being too close to affect the installation and fit between the support plate 81 and the electrical control box 50.

[0377] For example, the first limiting part 81211 is a limiting wire buckle, the second limiting part 81212 is a limiting through hole, and the wire harness part 552 is a vertical wire buckle. The power cord 101 is limited and engaged with the first limiting part 81211, which is actually the power cord 101 being limited and engaged with the limiting wire buckle. The limiting wire buckle not only has a simple structure, which facilitates the processing of the first limiting part 81211 on the support plate 81, but also provides reliable limiting of the power cord 101, preventing the power cord 101 from falling off the control board and ensuring the reliable position of the power cord 101 on the control board.

[0378] For example, the limiting fit between the power cord 101 and the second limiting part 81212 is actually the limiting fit between the power cord 101 and the limiting through hole, which is located on the edge of the support plate 81 near the power cord outlet 163.

[0379] In this way, not only can the processing of the second limiting part 81212 on the support plate 81 be simplified, but the power cord 101 and the second limiting part 81212 can also be effectively prevented from falling off, thereby ensuring the limiting reliability of the power cord 101 and the second limiting part 81212.

[0380] For example, a vertical cable clip is provided at the cable outlet of the control box 50. This clip not only has a simple structure and is easy to manufacture on the control box 50, but also ensures reliable cable bundling of the power cord 101 on the control box 50 via the cable bundling section 552. Furthermore, the open top of the cable clip facilitates the placement and removal of the power cord 101, thereby improving the ease of installation and removal of the power cord 101 in the portable air conditioner 100.

[0381] In some embodiments, as shown in Figures 40 and 41, the electrical control box 50 is provided with a control harness for connecting the compressor 30, and the first side plate 812 is provided with a constraint portion 813 through which the control harness passes. For example, in addition to the power line 101 for connecting to an external power source, the electrical control box 50 is also provided with a control harness, which includes, but is not limited to, being electrically connected to the compressor 30, so that the electrical control box 50 can control the compressor 30 to operate normally.

[0382] For example, a constraint part 813 is also provided on the first side plate 812. The constraint part 813 corresponds to the position where the control wire harness extends from the electrical control box 50. In this way, after the control wire harness extends from the electrical control box 50, it can pass through the constraint part 813, so that the control wire harness can be routed close to the support plate 81, which can reduce the control wire harness occupying more of the storage space 14.

[0383] In addition, the constraint part 813 can guide the control harness from the control box 50 to the compressor 30, and can control the routing of the control harness in the portable air conditioner 100, making the routing of the control harness in the portable air conditioner 100 neater and simpler, thereby optimizing the arrangement of the control harness in the portable air conditioner 100.

[0384] In some embodiments, as shown in FIG40, a fixing member 164 is provided on the chassis 16. The fixing member 164 is located between the limiting part 8121 and the power cord outlet 163. A through hole is formed between the fixing member 164 and the chassis 16, and the power cord 101 passes through the through hole.

[0385] For example, a fixing member 164 is also provided between the power cord outlet 163 and the second limiting part 81212. The fixing member 164 is disposed on the chassis 16, which can ensure the stability of the fixing member 164 in the accommodating space 14, thereby ensuring the reliability of the fixing member in fixing the wiring harness in the portable air conditioner 100. It should be noted that the fixing method between the fixing member 164 and the chassis 16 in the embodiments of the present invention includes, but is not limited to, snap-fit ​​fixing.

[0386] For example, the fixing member 164 and the base 16 together form a through hole. When the power cord 101 passes through this through hole, the fixing member 164 and the base 16 can work together to fix and support the power cord 101. This arrangement not only ensures that the power cord 101 is stably positioned between the second limiting part 81212 and the power cord outlet 163, but also guides the power cord 101 to the power cord outlet 163 so that the power cord 101 can smoothly extend from the power cord outlet 163.

[0387] For example, the fastener 164 is detachably fixed to the chassis 16, so that when installing the power cord 101, the power cord 101 can be placed at the position of the corresponding through hole in the chassis 16, and then the fastener 164 is fixed to the chassis 16, so that the power cord 101 is fixed in the through hole formed by the fastener 164 and the chassis 16.

[0388] When disassembling the power cord 101, the fastener 164 can be removed from the chassis 16, which opens the perforated part and makes it easy to remove the power cord 101 from the chassis 16, thereby improving the ease of disassembly and assembly of the power cord 101.

[0389] In some embodiments, as shown in FIG40, the electrical control box 50 further includes a box body 55, one side of which is open, which facilitates the installation of electrical control components, heat sinks 51, power cords 101 and control harnesses in the electrical control box 50.

[0390] As shown in Figure 40, the electrical control box 50 also includes a cover 56. After the electrical control components, heat sink 51, power cord 101 and control wiring harness are installed inside the box 55, the cover 56 can be placed on the open side of the box 55. This can protect the electrical control components, heat sink 51, power cord 101 and control wiring harness inside the electrical control box 50, and ensure that the electrical control box 50 works normally.

[0391] For example, the support plate 81 is located on the side of the box 55 away from the cover 56. The support plate 81 is provided with a heat dissipation grille 8111, so that the heat dissipation grille 8111 corresponds to the heat sink 51 in the electrical control box 50, which helps to improve the heat dissipation efficiency of the electrical control box 50 and thus ensures the working safety of the electrical control box 50.

[0392] For example, the support plate 81 is provided with a first through hole 8141, the box body 55 is provided with a second through hole 5531, and the cover body 56 is provided with a third through hole 5611. The first through hole 8141, the second through hole 5531 and the third through hole 5611 correspond to each other, so that a fastener can be used to pass through the first through hole 8141, the second through hole 5531 and the third through hole 5611 to lock the first through hole 8141, the second through hole 5531 and the third through hole 5611.

[0393] With this configuration, the control box 50 and the support plate 81 can be connected and fixed by a fastener. This allows the control box 50 to be connected to the support plate 81, which is supported between the chassis 16 and the first water receiving tray 80. This provides support for the control box 50, preventing it from shaking in the portable air conditioner 100 and ensuring its structural stability and operational safety.

[0394] On the other hand, by connecting the cover 56, the box 55 and the support plate 81 of the control box 50 with only one fastener, the number of parts of the portable air conditioner 100 can be simplified, and the assembly convenience of the control box 50 and the support plate 81 can be improved. This is conducive to reducing the manufacturing cost of the portable air conditioner 100 and improving the production efficiency of the portable air conditioner 100.

[0395] In some embodiments, as shown in Figures 42 and 43, a first mounting piece 553 is provided on the housing 55, and a second mounting piece 561 is provided on the cover 56. A second through hole 5531 is provided on the first mounting piece 553, and a third through hole 5611 is provided on the second mounting piece 561. The first mounting piece 553 and the second mounting piece 561 fit together. A mounting post 814 is provided on the support plate 81, and a first through hole 8141 is provided on the mounting post 814. The mounting post 814 extends toward the first mounting piece 553 and abuts against the first mounting piece 553.

[0396] For example, providing a first mounting piece 553 on the housing 55 can provide an opening position for the second through hole 5531 while maintaining the structure of the housing 55. Providing a second mounting piece 561 on the cover 56 can provide an opening position for the third through hole 5611 while maintaining the structure of the cover 56.

[0397] Before the fasteners pass through the first through hole 8141, the second through hole 5531, and the third through hole 5611, the first mounting piece 553 and the second mounting piece 561 are first made to fit together so that the second through hole 5531 and the third through hole 5611 correspond. This makes the first through hole 8141, the second through hole 5531, and the third through hole 5611 correspond and close to each other, so that the fasteners can pass directly through the first through hole 8141, the second through hole 5531, and the third through hole 5611, thereby improving the installation convenience of the electrical control box 50 and the support plate 81.

[0398] This not only facilitates the sequential insertion of fasteners through the second through hole 5531 and the third through hole 5611, but also increases the contact area between the box body 55 at the second through hole 5531 and the cover body 56 at the third through hole 5611. This enhances the connection strength between the fasteners and the second through hole 5531 and the third through hole 5611, increases the strength of the box body 55 at the second through hole 5531, and increases the strength of the cover body 56 at the third through hole 5611. This ensures the reliability of the connection between the fasteners and the box body 55 and the cover body 56.

[0399] For example, a mounting post 814 is provided on the support plate 81, and a first through hole 8141 is provided in the mounting post 814. This facilitates the machining of the first through hole 8141 on the support plate 81. The mounting post 814 extends horizontally, and a relatively deep first through hole 8141 can be provided. The end of the fastener extends into the first through hole 8141, which increases the contact area between the fastener and the mounting post 814, and helps to improve the connection reliability between the fastener and the support plate 81. With this arrangement, when the fastener passes through the first through hole 8141, the second through hole 5531 and the third through hole 5611 in sequence, the connection reliability between the electrical control box 50 and the support plate 81 can be improved.

[0400] According to some embodiments of this disclosure, as shown in FIG26, a first notch 86 is formed at one end of the first water receiving tray 80. The first notch 86 is configured to connect the space below the first water receiving tray 80 and the ventilation channel of the outdoor air duct assembly 20.

[0401] The first water receiving tray 80 is provided with a first notch 86, which allows the wire to pass through, thus facilitating wire routing, protecting the wire, preventing damage to the wire, and improving the safety of the wire.

[0402] For example, the negative pressure generated by the outdoor air duct component 20 can attract the line to the first notch 86, thereby fixing the line.

[0403] According to some embodiments of this disclosure, the outdoor air duct assembly 20 and the indoor air duct assembly 40 are respectively connected to the outdoor heat exchanger 60 and the indoor heat exchanger 70 via wiring harnesses. The outdoor heat exchanger 60 and the indoor heat exchanger 70 are respectively connected to the compressor 30 via pipes. The wiring harnesses and pipes are provided with air passages.

[0404] The outdoor air duct assembly 20 can be electrically connected to the outdoor heat exchanger 60 via a wiring harness, thereby enabling heat exchange in the outdoor heat exchanger 60. The indoor air duct assembly 40 can be electrically connected to the indoor heat exchanger 70 via a wiring harness, thereby enabling heat exchange in the indoor heat exchanger 70.

[0405] For example, ventilation channels can be installed for wiring harnesses and conduits, which can facilitate the placement of wiring harnesses and conduits and thus protect them.

[0406] Furthermore, the outdoor heat exchanger 60 is a condenser, which cools the refrigerant in the air conditioning system into a liquid state, thereby releasing heat. The condenser draws heat from the room into the air conditioning system through refrigerant circulation and then exhausts the heat outdoors, thus lowering the indoor temperature.

[0407] The outdoor heat exchanger 60 is an evaporator that evaporates the refrigerant into a gaseous state, thereby absorbing heat from the room and lowering the indoor temperature. The evaporator circulates indoor air through a fan, drawing heat from the room into the air conditioning system, where the heat is then absorbed and evaporated by the refrigerant, thus reducing the indoor temperature.

[0408] According to some embodiments of this disclosure, as shown in FIG49, a second water receiving tray 88 is disposed above the outdoor heat exchanger 60 and the outdoor air duct assembly 20, and an indoor heat exchanger 70 and an indoor air duct assembly 40 are disposed above the second water receiving tray 88.

[0409] The second water receiving tray 88 is positioned above the outdoor heat exchanger 60 and the outdoor air duct assembly 20. In this way, the second water receiving tray 88 can isolate the outdoor heat exchanger 60 and the indoor heat exchanger 70, as well as the outdoor air duct assembly 20 and the indoor air duct assembly 40.

[0410] Thus, the compressor 30 and electrical components 52 are located at the bottom layer of the portable air conditioner 100, the outdoor heat exchanger 60 and outdoor air duct assembly 20 are located at the second layer of the portable air conditioner 100, and the indoor heat exchanger 70 and indoor air duct assembly 40 are located at the top layer, i.e., the third layer, of the portable air conditioner 100. This allows for a multi-layered layout within the portable air conditioner 100, offering the advantages of a hierarchical design and also helping to reduce the width and thickness of the portable air conditioner 100.

[0411] Furthermore, the first water receiving tray 80 is positioned above the compressor 30 (e.g., directly above it), which not only serves to isolate the outdoor air duct assembly 20 and the electrical components 52, but also to isolate the outdoor heat exchanger 60 and the compressor 30. In this way, the compressor 30 and the electrical components 52 are located on the bottom layer, while the outdoor air duct assembly 20 and the outdoor heat exchanger 60 are located on the second layer, thus forming a two-layer structure and avoiding interference.

[0412] For example, the outdoor heat exchanger 60 is arranged opposite to the compressor 30, and the outdoor heat exchanger 60 is located above the compressor 30 (such as directly above it). In this way, the outdoor heat exchanger 60 and the compressor 30 are arranged in a corresponding manner, which can better prevent the condensate at the outdoor heat exchanger 60 from flowing to the electrical device 52, thereby ensuring the safety and stability of the circuit transmission to the electrical device 52.

[0413] Furthermore, the outdoor air duct assembly 20 is positioned above the power supply device 52 (e.g., directly above it), which shortens the distance between the power supply device 52 and the circuit connection of the outdoor air duct assembly 20, thereby preventing the wiring from getting tangled and ensuring the stability of the wiring connection.

[0414] In some embodiments, as shown in FIG49, the portable air conditioner 100 further includes a duct assembly 200, which includes an air inlet duct 43. One end of the air inlet duct 43 is connected to the outdoor air inlet 601 of the outdoor air duct component 21. The duct assembly 200 also includes an air outlet duct 44, one end of which is connected to the outdoor air outlet 602 of the outdoor air duct component 21. The air inlet duct 43 is used to draw in fresh air from the outside, and the air outlet duct 44 is configured to exhaust the heat generated by the outdoor air duct assembly 20 to the outside, preventing indoor air from becoming hot.

[0415] For example, when the outdoor duct assembly 20 is running, the outdoor fan 22 in the outdoor duct component 21 rotates, drawing outdoor air in through the air inlet duct 43. The outdoor air enters the outdoor duct assembly 20 through the outdoor air inlet 601 and exchanges heat with the outdoor heat exchanger 60, which is a condenser. The refrigerant, after being compressed by the compressor 30, becomes a high-temperature, high-pressure state and enters the outdoor heat exchanger 60, where it exchanges heat with the outdoor air. The refrigerant in the outdoor heat exchanger 60 condenses and releases heat, becoming a high-pressure, low-temperature liquid. It then enters the indoor duct assembly 40 through the expansion valve. The outdoor air temperature rises after heat exchange and, under the action of the outdoor fan 22, is discharged to the outside through the outdoor air outlet 602 and the air outlet duct 44, dissipating the heat in the outdoor duct assembly 20 to the outside.

[0416] In some embodiments, as shown in FIG53, the duct assembly 200 further includes a first mounting plate 201. The first mounting plate 201 is provided with a first air inlet 202, and the other end of the air inlet pipe 43 is connected to the first air inlet 202. The first mounting plate 201 is also provided with a first air outlet 204, and the other end of the air outlet pipe 44 is connected to the first air outlet 204.

[0417] For example, as shown in Figure 49, the first mounting plate 201 is fixedly connected to the upper ends of the air inlet pipe 43 and the air outlet pipe 44, respectively. The first mounting plate 201 is provided with a first air inlet 202. Outdoor air first enters the air inlet pipe 43 through the first air inlet 202, and then enters the outdoor air duct assembly 20 through the outdoor air inlet 601 at one end of the air inlet pipe 43. It can be understood that the outdoor air after heat exchange first enters the air outlet pipe 44 through the outdoor air outlet 602, and then is discharged to the outside through the first air outlet 204 at the other end of the air outlet pipe 44.

[0418] In some embodiments, as shown in FIG50, a third snap-fit ​​portion 206 is provided on the first mounting plate 201, and a fourth snap-fit ​​portion 218 is provided on the rear side of the housing 10. The third snap-fit ​​portion 206 and the fourth snap-fit ​​portion 218 are snap-fitted together. By engaging the third snap-fit ​​portion 206 and the fourth snap-fit ​​portion 218, the first mounting plate 201 can be fixed to the rear side of the housing 10, and the air inlet pipe 43 and the air outlet pipe 44 can be fixed.

[0419] Understandably, when the portable air conditioner 100 is not in use, the air inlet duct 43, air outlet duct 44, and the first mounting plate 201 are stored together on the rear side of the outer casing 10. This saves indoor space, especially in areas where the portable air conditioner 100 is used, which are generally small spaces with many items. This prevents the air inlet duct 43 and air outlet duct 44 from taking up too much indoor space. Storing the air inlet duct 43 and air outlet duct 44 also effectively prevents the ducts from being accidentally stepped on or bumped, reducing the risk of damage to the air inlet duct 43 and air outlet duct 44 and helping to extend the service life of the portable air conditioner 100.

[0420] In some embodiments, when the portable air conditioner 100 is in use, the first mounting plate 201 and one end of the air inlet pipe 43 and air outlet pipe 44 are removed from the rear side of the outer casing 10 and fixed to the window. The first mounting plate 201 and the outer casing 10 are fixed by snap-fit, which has high stability and firmness. The first mounting plate 201 is not easy to loosen or fall off. Compared with bolt connection or clamp connection, snap-fit ​​is easier to disassemble and assemble. The operation of taking off and putting away the first mounting plate 201 is simple and quick, saving users time and improving the convenience of using the portable air conditioner 100.

[0421] Moreover, the snap-fit ​​connection is more compact, neat, and aesthetically pleasing, with no exposed sharp structures and no need for additional accessories. The first mounting plate 201 has a simple structure, which can reduce processing costs and has good economic benefits.

[0422] Therefore, by setting the third latching part 206 and the fourth latching part 218, the assembly and disassembly of the first mounting plate 201 and the rear side of the outer casing 10 are made easier and faster. The first mounting plate 201 has a simple structure, which reduces the processing cost of the portable air conditioner 100 while improving the user's convenience.

[0423] In some embodiments, referring to Figures 49 and 50, the third snap-fit ​​portion 206 is one of a buckle and a slot, and the fourth snap-fit ​​portion 218 is the other of a buckle and a slot, with the buckle and slot engaging in a snap-fit ​​connection. In this embodiment of the invention, the third snap-fit ​​portion 206 is a slot, and the fourth snap-fit ​​portion 218 is a buckle. Through the snap-fit ​​connection of the buckle and the slot, the first mounting plate 201 can be fixed to the rear side of the housing 10.

[0424] For example, the third latching part 206 can also be a buckle, and the fourth latching part 218 can be a card slot.

[0425] It should be noted that, as shown in Figures 50 and 52, the buckle includes a limiting plate 219, which is connected to the outer shell 10. The buckle also includes two second side plates 221, which are disposed on both sides of the limiting plate 219 and are connected to the outer shell 10.

[0426] For example, the buckle and the outer shell 10 are integrally formed. The buckle protrudes from the rear side of the outer shell 10 and bends upward. The upwardly bent part is a limiting plate 219. The limiting plate 219 is used to engage with the slot on the first mounting plate 201. The limiting plate 219 extends into the slot and can limit the relative position of the first mounting plate 201 and the outer shell 10, so that the first mounting plate 201 and the outer shell 10 can be fixed.

[0427] The limiting plate 219 has two second side plates 221 on both sides. The second side plates 221 serve as the supporting structure of the limiting plate 219, which can prevent the buckle from tilting or deforming during use and increase the structural strength, load-bearing capacity and stability of the buckle.

[0428] In some embodiments, as shown in Figures 50 and 51, a first limiting protrusion 220 is provided on the side of the limiting plate 219 facing the housing 10. For example, the first limiting protrusion 220 is provided at the upper end of the limiting plate 219 for engaging with the edge of the slot. The first limiting protrusion 220 can, to a certain extent, limit the relative movement of the first mounting plate 201 and the housing 10 in the height direction.

[0429] For example, the first limiting protrusion 220 engages with the edge of the slot on the first mounting plate 201, preventing the first mounting plate 201 from moving downwards in the left-right, front-back, or up-down directions, thus securing the first mounting plate 201 and the outer casing 10. It should be noted that when the user needs to remove the first mounting plate 201, forcefully separating the first limiting protrusion 220 from the slot allows the first mounting plate 201 to be separated from the outer casing 10 from above. This prevents accidental separation of the first mounting plate 201 from the outer casing 10 due to misoperation, improving the safety and reliability of the portable air conditioner 100.

[0430] In some embodiments, as shown in FIG51, the outer shell 10 is provided with a first through hole 225, which corresponds to the limiting plate 219. For example, the first through hole 225 is provided on the rear side of the outer shell 10 at a position corresponding to the limiting plate 219. During the snap-fit ​​molding process, structural deformation may occur due to material shrinkage. Providing the first through hole 225 on the outer shell 10 can improve the fluidity of the material, reduce the internal stress of the material during the molding process, reduce the risk of snap-fit ​​deformation, and improve production efficiency.

[0431] In some embodiments, as shown in Figures 53 to 55, a receiving groove 222 is provided on the rear side of the housing 10, at least a portion of the duct assembly 200 is disposed in the receiving groove 222, and a sixth snap-fit ​​portion 210 is provided at both ends of the receiving groove 222. A fifth snap-fit ​​portion 207 is provided on both sides of the first mounting plate 201 in the left-right direction, and the two fifth snap-fit ​​portions 207 and the two sixth snap-fit ​​portions 210 are snap-fitted together.

[0432] For example, the rear side of the outer casing 10 is recessed inward to form a receiving groove 222. When the portable air conditioner 100 is not in use, the air inlet pipe 43 and the air outlet pipe 44 can be placed in the receiving groove 222. At both ends of the receiving groove 222, that is, at both ends of the outer casing 10 in the left and right directions, there is a sixth snap-fit ​​part 210. At both ends of the first mounting plate 201 in the left and right directions, there is a fifth snap-fit ​​part 207. The positions of the fifth snap-fit ​​part 207 and the sixth snap-fit ​​part 210 are corresponding, and the fifth snap-fit ​​part 207 and the sixth snap-fit ​​part 210 are snap-fitted together to fix the first mounting plate 201 and the rear side of the outer casing 10.

[0433] Referring to Figures 53 to 55, the first mounting plate 201 is provided with a plurality of fifth snap-fit ​​parts 207 around the first air inlet 202 and the first air outlet 204. The plurality of fifth snap-fit ​​parts 207 are used to snap into the window mounting bracket. That is, when the portable air conditioner 100 is in use, the first mounting plate 201 is removed from the outer casing 10, and the plurality of fifth snap-fit ​​parts 207 are used to fix the first mounting plate 201 to the window mounting bracket, so that the outdoor air duct assembly 20 can draw in air from the outside and expel heat.

[0434] In the embodiments of this disclosure, there are six fifth latching portions 207. These six fifth latching portions 207 are evenly spaced on the first mounting plate 201 and symmetrically arranged in both the left-right and front-back directions. This ensures more even force distribution on the first mounting plate 201, preventing issues such as buckling or deformation of the first mounting plate 201 due to uneven force, thus improving product quality. Furthermore, the multiple latches located in different positions increase user choice and provide more adjustment options in environments where there is no suitable fixing position near windows, increasing product usability.

[0435] For example, as shown in FIG54, the fifth latching part 207 is a buckle, which includes a latching part 208 and a first unlocking part 209. The latching part 208 is disposed at the upper end of the first mounting plate 201 and is configured to latch with the mounting bracket. The first unlocking part 209 is connected to the latching part 208 and passes through the first mounting plate 201 and is located at the lower end of the first mounting plate 201 so that the latching part 208 and the mounting bracket are separated when the first unlocking part 209 is pressed.

[0436] It should be noted that the latching part 208 is provided with a protruding portion, which latches onto the mounting bracket, thus fixing the first mounting plate 201 and the mounting bracket, facilitating the outdoor air duct assembly 20 to draw in outdoor air and expel heat. After the user has finished using the portable air conditioner 100, they can press the first unlocking part 209. The first unlocking part 209 is elastic, and it retracts towards the first mounting plate 201, causing the latching part 208 to move, thereby separating the latching part 208 from the mounting bracket, allowing the first mounting plate 201 to be removed from the mounting bracket.

[0437] For example, after the first mounting plate 201 is fixed to the mounting bracket, the first unlocking part 209 faces the indoor side, which makes it easier for the user to perform the unlocking operation and provides greater convenience.

[0438] In some embodiments, as shown in Figures 53, 56, and 57, a second mounting plate 211 is provided on the duct assembly 200, and a second air inlet 212 is provided on the second mounting plate 211. One end of the air inlet duct 43 is connected to the second air inlet 212, and a second air outlet 213 is provided on the second mounting plate 211. One end of the air outlet duct 44 is connected to the second air outlet 213, and the second mounting plate 211 is fixed to the outer casing 10.

[0439] The second mounting plate 211 is fixedly connected to the lower ends of the air inlet pipe 43 and the air outlet pipe 44 respectively. The outdoor air drawn in first enters the air inlet pipe 43 through the first air inlet 202 of the first mounting plate 201, then passes through the second air inlet 212 of the second mounting plate 211, and finally enters the outdoor air duct assembly 20 through the outdoor air inlet 601. After heat exchange, the air enters the air outlet pipe 44 through the outdoor air outlet 602 and the second air outlet 213 of the second mounting plate 211, and finally is discharged to the outside through the first air outlet 204 of the first mounting plate 201.

[0440] The second mounting plate 211 is fixedly connected to the outer casing 10, which can fix the lower ends of the air inlet pipe 43 and the air outlet pipe 44 to the outer casing 10, ensuring the stable operation of the air conditioning system.

[0441] In some embodiments, referring to FIG52, the front side of the second mounting plate 211 is provided with a plurality of second limiting protrusions 214 spaced apart in the left-right direction, and the outer shell 10 is provided with a plurality of limiting grooves 223. The plurality of second limiting protrusions 214 and the plurality of limiting grooves 223 are mutually limitingly engaged. Through the limiting engagement of the second limiting protrusions 214 and the limiting grooves 223, the second mounting plate 211 can be fixed to the rear side of the outer shell 10. In the embodiments of this disclosure, there are three second limiting protrusions 214 on the second mounting plate 211 and three limiting grooves 223 on the rear side of the outer shell 10, and the three second limiting protrusions 214 and the limiting grooves 223 correspond to each other.

[0442] In some embodiments, the second limiting protrusion 214 and the limiting groove 223 may be four, five or more, and multiple limiting grooves 223 may be provided on the second mounting plate 211, and multiple second limiting protrusions 214 may be provided on the outer shell 10. The second limiting protrusions 214 and the limiting grooves 223 correspond to fix the second mounting plate 211 and the outer shell 10.

[0443] Furthermore, a first mounting portion 215 is provided on the rear side of the second mounting plate 211 (as shown in Figure 53), and a second mounting portion 224 is provided on the outer casing 10 (as shown in Figure 52). The first mounting portion 215 and the second mounting portion 224 are fitted together. The first mounting portion 215 and the second mounting portion 224 can be screw holes. Fasteners are passed through the first mounting portion 215 and the second mounting portion 224 to fix the second mounting plate 211 and the outer casing 10. By fixing the second mounting plate 211 and the outer casing 10 in multiple ways, the force on the second mounting plate 211 and the outer casing 10 is more even, and the fixation is more secure, ensuring the safety of the portable air conditioner 100 during use.

[0444] For example, a fastener can be a screw.

[0445] In some embodiments, referring to FIG56, a seventh snap-fit ​​portion 216 is provided on the first mounting plate 201, and the other end of the air inlet pipe 43 or the other end of the air outlet pipe 44 is snap-fitted into the seventh snap-fit ​​portion 216. The seventh snap-fit ​​portion 216 may be threaded, and the thread is provided on the inner wall of the first mounting plate 201 where the air inlet pipe 43 and the air outlet pipe 44 are fixed. Since the air inlet pipe 43 and the air outlet pipe 44 may be corrugated pipes, the thread can lock the corrugation of the corrugated pipe, and the air inlet pipe 43 and the air outlet pipe 44 can be snapped onto the first mounting plate 201.

[0446] Furthermore, the second mounting plate 211 is provided with an eighth snap-fit ​​part 217, which engages with one end of the air inlet pipe 43 or one end of the air outlet pipe 44. The eighth snap-fit ​​part 217 can be a buckle that holds the corrugated pipe's texture, allowing the air inlet pipe 43 and the air outlet pipe 44 to be snapped onto the second mounting plate 211.

[0447] In the embodiments of this disclosure, there are eight eighth snap-fit ​​parts 217, four of which snap-fit ​​with the air inlet pipe 43 and four of which snap-fit ​​with the air outlet pipe 44. The eighth snap-fit ​​parts 217 are evenly spaced to ensure that the air inlet pipe 43 and the air outlet pipe 44 are subjected to uniform force, thereby improving the stability of the fixation.

[0448] In addition, an eighth snap-fit ​​part 217 is provided at the end where the second mounting plate 211 is fixed to the air inlet pipe 43. The eighth snap-fit ​​part 217 can also be threaded. The thread is provided on the inner wall where the second mounting plate 211 is fixed to the air inlet pipe 43. Since the air inlet pipe 43 is a corrugated pipe, the thread can lock the corrugated pipe's texture, and the air inlet pipe 43 can be snapped onto the second mounting plate 211.

[0449] In some embodiments, as shown in FIG53, an air inlet grille 203 is provided at the first air inlet 202, and an air outlet grille 205 is provided at the first air outlet 204. The air inlet grille 203 and the air outlet grille 205 are inclined relative to each other in the vertical direction, and the air inlet grille 203 and the air outlet grille 205 have different orientations. The air outlet grille 205 and the air inlet grille 203 can protect the internal structure of the outdoor air duct assembly 20 from dust, debris, etc. entering the outdoor air duct assembly 20, ensuring the normal operation of the outdoor air duct assembly 20 and extending its service life. On the other hand, they can adjust the airflow direction and speed of the air inlet and outlet. The air outlet grille 205 and the air inlet grille 203 are inclined in a direction away from each other, which helps to prevent the airflow of the air inlet pipe 43 and the air outlet pipe 44 from interfering with each other.

[0450] In some embodiments, referring to Figures 59 and 60, the indoor air duct assembly 40 includes a third air duct plate 415. The third air duct plate 415 and the indoor heat exchanger 70 define a second air duct, in which an indoor fan 42 is disposed. The indoor air duct assembly 40 also includes a fourth air duct plate 416 disposed within the second air duct. At least a portion of the fourth air duct plate 416, the third air duct plate 415, and at least a portion of the indoor heat exchanger 70 together define a first chamber 417.

[0451] An indoor fan 42 is installed inside the third air duct plate 415, and the third air duct plate 415 and the indoor heat exchanger 70 define the second air duct. The indoor fan 42 rotates, driving the airflow to enter from the indoor air inlet 11. After exchanging heat with the indoor heat exchanger 70, the airflow is blown out along the second air duct, thereby lowering or raising the indoor temperature.

[0452] In some embodiments, referring to Figures 58 and 61, the fourth duct plate 416 is a semi-enclosed structure with one end open. At least a portion of the fourth duct plate 416 and the third duct plate 415, and at least a portion of the indoor heat exchanger 70 together define the first chamber 417. The volume of the fourth duct plate 416 is relatively smaller than that of the third duct plate 415. The fourth duct plate 416 is disposed in the second duct and adjacent to a portion of the indoor heat exchanger 70. When the airflow of the second duct passes through the fourth duct plate 416, since the fourth duct plate 416 occupies a portion of the second duct, the flow velocity is faster in a smaller space under the same air volume. Therefore, the fourth duct plate 416 can increase the airflow velocity blown into the room, and the effect of improving the indoor temperature is greater.

[0453] It should be noted that designing the fourth air duct plate 416 to be hollow inside, together with at least a portion of the third air duct plate 415 and at least a portion of the indoor heat exchanger 70, defines the first chamber 417, which can save materials and reduce costs while increasing airflow velocity.

[0454] In some embodiments, the third air duct plate 415 is provided with a first mating part, and the fourth air duct plate 416 is provided with a second mating part. The third air duct plate 415 and the fourth air duct plate 416 are detachably connected through the first and second mating parts. This detachable connection between the first and second mating parts allows the indoor air duct assembly 40 to be a separate unit. During mold design and production, the third air duct plate 415 and the fourth air duct plate 416 can be designed and produced separately. Smaller molds are more convenient to process, simpler to operate, reduce processing difficulty and transportation costs, and occupy relatively less production space, reducing the occupation of production equipment and work area, improving production efficiency and equipment utilization, and effectively reducing costs.

[0455] It should be noted that indoor air can enter the outer casing 10 through the air inlet of the second air duct and pass through the indoor heat exchanger 70, and then be blown to the indoor user from the air outlet of the second air duct.

[0456] In addition, the characteristics of the indoor air duct assembly 40 are different in different products. For example, the indoor fan 42 of different air conditioning products will have different sizes. By using the split indoor air duct assembly 40, the fourth air duct plate 416 can be replaced according to the different characteristics of the product. Specifically, when the indoor fan 42 is larger, a smaller fourth air duct plate 416 can be replaced, and when the indoor fan 42 is smaller, a larger fourth air duct plate 416 can be replaced.

[0457] Furthermore, since the fourth air duct plate 416 is smaller in size, less raw materials are needed for mold manufacturing, resulting in lower costs. Only the fourth air duct plate 416 needs to be replaced without replacing the third air duct plate 415, eliminating the need to re-mold the entire indoor air duct assembly 40. This allows it to adapt to air conditioning products of different specifications and requirements at a low cost.

[0458] In some embodiments, the third air duct plate 415 is provided with first mating portions at both ends in the height direction, and the fourth air duct plate 416 is provided with second mating portions at both ends in the height direction. The fourth air duct plate 416 is connected to the third air duct plate 415 in the height direction. Specifically, the upper and lower edges of the third air duct plate 415 are provided with first mating portions, and the upper and lower edges of the fourth air duct plate 416 are provided with second mating portions. The third air duct plate 415 and the fourth air duct plate 416 can be connected through the first and second mating portions to form a stable structure.

[0459] In some embodiments, referring to Figures 58 and 61, the first mating part is one of a groove 4154 and a slider 4161, and the second mating part is the other of a groove 4154 and a slider 4161, with the groove 4154 and the slider 4161 in sliding engagement. For example, a groove 4154 is provided at the upper and lower ends of the third air duct plate 415 in the height direction, and a slider 4161 is provided at the upper and lower ends of the fourth air duct plate 416 in the height direction. The groove 4154 and the slider 4161 are positioned correspondingly. The relative position of the third air duct plate 415 and the fourth air duct plate 416 can be changed by moving the slider 4161 inside the groove 4154. That is, the fourth air duct plate 416 can slide out of the third air duct plate 415 by sliding, which allows for convenient replacement of the fourth air duct plate 416.

[0460] It is understandable that sliders 4161 can be provided at the upper and lower ends of the third air duct plate 415 in the height direction, and grooves 4154 can be provided at the upper and lower ends of the fourth air duct plate 416 in the height direction. The positions of the grooves 4154 and the sliders 4161 correspond, and the fourth air duct plate 416 can slide out of the third air duct plate 415 by sliding, thereby replacing the fourth air duct plate 416.

[0461] In some embodiments, referring to FIG60, the third air duct plate 415 includes a first top plate 4151. The third air duct plate 415 also includes a bottom plate 4152. The third air duct plate 415 also includes a third side plate 4153. The third side plate 4153 is connected between the first top plate 4151 and the bottom plate 4152, and the first top plate 4151 and the bottom plate 4152 are respectively provided with first mating parts and are arranged vertically opposite to each other.

[0462] It should be noted that the first top plate 4151 is located on top of the indoor air duct component 41, which can seal the indoor air duct component 41, prevent air leakage from affecting the air output effect of the portable air conditioner 100, and also prevent the external environment from affecting the indoor air duct component 41. For example, the first top plate 4151 can protect the indoor fan 42, filter and other components inside the indoor air duct component 41 from the intrusion of external objects and dust, extend the service life and improve product quality.

[0463] In some embodiments, as shown in FIG60, the base plate 4152 is located at the bottom of the indoor air duct component 41, which can support the structure of the indoor air duct component 41 and fix the position of the third air duct plate 415. Furthermore, the base plate 4152 can also be used to connect components such as fans and motors to maintain the stability and fixed position of the fans, motors, etc.

[0464] In some embodiments, the third side plate 4153 is connected between the first top plate 4151 and the bottom plate 4152, so that the relatively closed structure formed by the indoor air duct component 41 ensures that the airflow flows in the indoor air duct component 41 along a predetermined path, which facilitates the adjustment and control of the airflow rate.

[0465] The first top plate 4151 and the bottom plate 4152 are respectively provided with a first mating part. The first mating part can be either a slider 4161 or a slide groove 4154. The slider 4161 and the slide groove 4154 are arranged opposite each other, so that the fourth air duct plate 416 can slide out of the third air duct plate 415 by sliding, which makes it convenient to replace the fourth air duct plate 416.

[0466] In some embodiments, referring to Figures 59 and 61, a plurality of first mating portions are provided on the side wall of the third air duct plate 415 along the height direction. The first mating portions are first connecting portions 4155. At least one side of the fourth air duct plate 416 is provided with a plurality of second mating portions along the height direction. The second mating portions are second connecting portions 4162. A plurality of first connectors pass through the first connecting portions 4155 and are fixed to the second connecting portions 4162 accordingly. Specifically, the first connecting portions 4155 and the second connecting portions 4162 can be screw holes. In this embodiment of the invention, the number of first connecting portions 4155 and the number of second connecting portions 4162 is two. In other embodiments, the number of first connecting portions 4155 and the number of second connecting portions 4162 can also be three, four or more.

[0467] Multiple first connecting parts 4155 are spaced apart on the third air duct plate 415, and multiple second connecting parts 4162 are spaced apart on the fourth air duct plate 416. The first connecting parts 4155 and the second connecting parts 4162 are positioned correspondingly. By having a first connecting member pass through the first connecting parts 4155 and the second connecting parts 4162 in sequence, the first connecting parts 4155 can be fixed on the second connecting parts 4162, and the third air duct plate 415 and the fourth air duct plate 416 can be fixedly connected to form a stable fan assembly structure.

[0468] The first connector can be a bolt. In the embodiments disclosed herein, there are two first connectors. In other embodiments, there may be three, four or more first connectors.

[0469] In some embodiments, as shown in Figures 62 and 63, a plurality of first mating portions are provided on the side wall of the third air duct plate 415 along the height direction. The first mating portion is the eleventh snap-fit ​​portion 229 (see Figure 79). At least one side of the fourth air duct plate 416 is provided with a plurality of second mating portions along the height direction. The second mating portion is the twelfth snap-fit ​​portion 312 (see Figure 80). The eleventh snap-fit ​​portion 229 and the twelfth snap-fit ​​portion 312 are snap-fitted together.

[0470] For example, multiple eleventh snap-fit ​​parts 229 are spaced apart on the third air duct plate 415, and multiple twelfth snap-fit ​​parts 312 are spaced apart on the fourth air duct plate 416. The eleventh snap-fit ​​parts 229 and the twelfth snap-fit ​​parts 312 are positioned correspondingly. Through the snap-fit ​​cooperation of the eleventh snap-fit ​​parts 229 and the twelfth snap-fit ​​parts 312, the third air duct plate 415 and the fourth air duct plate 416 can be fixedly connected to form a stable fan assembly structure.

[0471] In the embodiments of this disclosure, there are four eleventh latching portions 229 and four twelfth latching portions 312. In other embodiments of the invention, the number of eleventh latching portions 229 and twelfth latching portions 312 may be increased or decreased, and may be two, three or more.

[0472] For example, the eleventh snap-fit ​​portion 229, the twelfth snap-fit ​​portion 312, the first connecting portion 4155, and the second connecting portion 4162 are arranged at intervals. The first connecting portion 4155 is located between two adjacent eleventh snap-fit ​​portions 229, and the second connecting portion 4162 is located between two adjacent twelfth snap-fit ​​portions 312. This provides multiple fixation for the third air duct plate 415 and the fourth air duct plate 416, ensuring the stability of the connection between the third air duct plate 415 and the fourth air duct plate 416 and improving product quality.

[0473] For example, the eleventh snap-fit ​​part 229 is one of a buckle and a latch, and the twelfth snap-fit ​​part 312 is the other of a buckle and a latch, with the buckle and latch engaging in a snap-fit ​​connection. Specifically, in this embodiment of the invention, the first connecting part 4155 is a latch, and the second connecting part 4162 is a buckle. Through the snap-fit ​​connection of the latch and the buckle, the eleventh snap-fit ​​part 229 and the twelfth snap-fit ​​part 312 can be fixedly connected, thereby fixing the third air duct plate 415 and the fourth air duct plate 416 in a fixed connection.

[0474] For example, the first connecting part 4155 can also be a buckle, and the second connecting part 4162 can be a bayonet. Through the snap-fit ​​of the bayonet and the buckle, the eleventh snap-fit ​​part 229 and the twelfth snap-fit ​​part 312 can be fixedly connected, thereby fixing the third air duct plate 415 and the fourth air duct plate 416 together.

[0475] In some embodiments, the positions of the eleventh snap-fit ​​portion 229, the twelfth snap-fit ​​portion 312, the first connecting portion 4155, and the second connecting portion 4162 can be interchanged. For example, in this embodiment, the first connecting portion 4155 is provided at the position of the eleventh snap-fit ​​portion 229, and in the embodiments disclosed herein, the second connecting portion 4162 is provided at the position of the twelfth snap-fit ​​portion 312. The number of the first connecting portion 4155 and the second connecting portion 4162 are four, and the number of the eleventh snap-fit ​​portion 229 and the twelfth snap-fit ​​portion 312 are two. Similarly, the third air duct plate 415 and the fourth air duct plate 416 can be fixedly connected.

[0476] It should be noted that the arrangement order of the eleventh snap-fit ​​part 229, the twelfth snap-fit ​​part 312, the first connecting part 4155, and the second connecting part 4162 can also be changed.

[0477] In some embodiments, referring to Figures 62 and 63, the heat exchanger 70 includes a heat exchanger body 701. The heat exchanger 70 also includes two first end plates 7011. The first end plates 7011 are disposed on both sides of the heat exchanger body 701. One first end plate 7011 is connected to one side of the third air duct plate 415, and the other first end plate 7011 is connected to the other side of the third air duct plate 415 and the other side of the fourth air duct plate 416. The first end plates 7011 are disposed at both ends of the heat exchanger body 701 and are configured to seal the heat exchanger body 701, preventing media leakage or external substances from entering the heat exchanger interior, ensuring stable and safe operation of the heat exchanger. The third air duct plate 415 is connected to the first end plates 7011 to fix the third air duct plate 415.

[0478] In addition, a buckle is provided on the side where the third air duct plate 415 is connected to another first end plate 7011 to fix the first end plate 7011.

[0479] In some embodiments, referring to Figures 58 to 61, a first mounting hole 4164 is provided on the other side of the fourth air duct plate 416, and a second mounting hole 4157 opposite to the first mounting hole 4164 is provided on the other side of the third air duct plate 415. Another first end plate 7011 is provided with a third mounting hole 70112. A second connector passes through the third mounting hole 70112 and the first mounting hole 4164 in sequence and is then fixed to the second mounting hole 4157. The second connector can be a bolt. By passing through the third mounting hole 70112 and the first mounting hole 4164 in sequence and then fixing to the second mounting hole 4157, the third air duct plate 415, the fourth air duct plate 416, and the heat exchanger can be fixedly connected together to form a stable structure.

[0480] It should be noted that there are four first mounting holes 4164, four second mounting holes 4157 and four third mounting holes 70112, and in other embodiments there may be five or more.

[0481] In some embodiments, as shown in Figures 59, 74, and 79, an indoor air outlet 4158 is provided on the third air duct plate 415, and a fourth air duct plate 416 is disposed on the inner side of the third air duct plate 415 near the indoor air outlet 4158. The fourth air duct plate 416, the inner side of the third air duct plate 415, and the inner side of the indoor heat exchanger 70 form a first chamber 417. The fourth air duct plate 416 can control the direction and speed of the airflow in the indoor air duct component 41 at the indoor air outlet 4158, allowing the airflow in the indoor air duct component 41 to flow towards the indoor air outlet 4158, thereby increasing the air volume supplied by the air conditioner.

[0482] In some embodiments, as shown in FIG75, the second water receiving tray 88 has a cavity with an upward opening 306. The second water receiving tray 88 is disposed at the bottom of the indoor heat exchanger 70 and is fixedly connected to the outer casing 10. The indoor heat exchanger 70 includes a second end plate 7012 disposed at its side end (as shown in FIG65).

[0483] For example, the indoor heat exchanger 70 is mounted on the second water receiving pan 88 so that the condensate on the indoor heat exchanger 70 can flow directly into the second water receiving pan 88. Furthermore, the second water receiving pan 88 is fixedly connected to the outer casing 10 to ensure that the indoor heat exchanger 70 is securely mounted on the second water receiving pan 88, thereby ensuring the stable operation of the indoor air duct assembly 40.

[0484] For example, a second end plate 7012 is provided on the side of the indoor heat exchanger 70 so that the second end plate 7012 is fixedly connected to surrounding components such as indoor air duct components 41, thereby ensuring that the indoor heat exchanger 70 is stably installed on the second water receiving tray 88.

[0485] In some embodiments, referring to Figures 68 and 69, the second end plate 7012 has a first plate portion 7015 and a second plate portion 7016, the first plate portion 7015 and the second plate portion 7016 extending in the vertical direction, the second plate portion 7016 being bent relative to the first plate portion 7015, the first plate portion 7015 being fixedly connected to the side end of the indoor heat exchanger 70, and the second plate portion 7016 being fixedly connected to its surrounding components.

[0486] For example, the indoor heat exchanger 70 of the present invention is fixedly connected to the indoor air duct component 41 by means of the second plate portion 7016, so as to realize the installation and fixation of the indoor heat exchanger 70.

[0487] The second water receiving tray 88 is provided with a strip-shaped protrusion 228, which surrounds the indoor heat exchanger 70 to limit the bottom sides of the indoor heat exchanger 70 and prevent the indoor heat exchanger 70 from moving.

[0488] Additionally, a raised strip is provided on the second water receiving tray 88, which is located at the bottom of the indoor heat exchanger 70 to support the indoor heat exchanger 70.

[0489] In some embodiments, the second water receiving tray 88 is provided with a plurality of limiting blocks on both sides of the bottom of the indoor heat exchanger 70 to limit the bottom of the indoor heat exchanger 70 and prevent the indoor heat exchanger 70 from moving.

[0490] It should be noted that the second water receiving tray 88 and the indoor heat exchanger 70 can also be fixed in other ways.

[0491] In some embodiments, as shown in FIG65, a first limiting stop 319 is provided on the second water receiving tray 88, and a second limiting stop 70121 is provided at one end of the second end plate 7012 near the second water receiving tray 88. The first limiting stop 319 and the second limiting stop 70121 provide limiting stops.

[0492] In some embodiments, a second limiting stop 70121 is provided on the second end plate 7012 at the side of the indoor heat exchanger 70 to limit and stop the indoor heat exchanger 70 with the first limiting stop 319 on the second water receiving pan 88. This can limit the indoor heat exchanger 70 and prevent it from moving on the second water receiving pan 88, which helps to enhance the stability of the indoor heat exchanger 70.

[0493] Typically, most systems use a limiting mechanism between the indoor heat exchanger 70 and the second water receiving tray 88. Based on this, this disclosure provides a second limiting stop 70121 on the second end plate 7012 at the side of the indoor heat exchanger 70 to limit and stop the indoor heat exchanger 70 against the first limiting stop 319 on the second water receiving tray 88, thereby better limiting and fixing the indoor heat exchanger 70.

[0494] In some embodiments, as shown in FIG65, the second end plate 7012 has a first flat plate 7013 arranged in a horizontal direction at one end near the second water receiving tray 88. The first flat plate 7013 has a first flange bent upward to form a second limiting stop portion 70121. The first flange and the first limiting stop portion 319 limit the stop in the horizontal direction.

[0495] For example, the lower end of the second end plate 7012 is provided with a first flat plate 7013 that bends outward, and a first flange that bends upward is provided on one side of the first flat plate 7013. The first flange and the first limiting stop 319 on the second water receiving tray 88 limit and stop each other in the horizontal direction, which can prevent the indoor heat exchanger 70 from moving and help to enhance the stability of the indoor heat exchanger 70.

[0496] It should be noted that "outer side" refers to the direction facing the outer side of the outer shell 10, and "horizontal direction" refers to the direction perpendicular to the height / vertical direction.

[0497] For example, a ribbed structure can be provided on the first plate 7013 so that the two ends of the ribbed structure are respectively connected to the first plate 7013 and the first flange, thereby improving the structural strength of the first flange and preventing the first flange from bending or breaking.

[0498] In some embodiments, a plate-like structure bent outward may be provided on one side of the lower end of the second end plate 7012 so that the plate-like structure and the first limiting stop 319 on the second water receiving tray 88 limit and stop each other in the horizontal direction, eliminating the need for the first plate 7013, simplifying the structure and reducing costs.

[0499] For example, the inner bottom of the second water receiving tray 88 is provided with an upwardly protruding first protrusion to form a first limiting stop 319, and the first protrusion and the first flange limit the stop in the horizontal direction.

[0500] The first protrusion and the first flange provide a horizontal upper limit stop, which effectively prevents the indoor heat exchanger 70 from moving on the second water receiving tray 88, thereby effectively enhancing the stability of the indoor heat exchanger 70.

[0501] The area of ​​the side of the first protrusion facing the first flange is approximately the same as the area of ​​the first flange, so as to ensure that the force of the first protrusion and the first flange blocking each other is the same, and that one of them will not deform.

[0502] In addition, the area of ​​the first flange can be larger than the area of ​​the side of the first protrusion facing the first flange. Since the structure of the first flange is relatively weaker than that of the first protrusion, the structural strength of the first flange can be improved and deformation can be prevented.

[0503] Furthermore, a reinforcing structure, such as a ribbed structure, can be added to the first flange to improve its structural strength.

[0504] In some embodiments, as shown in FIG68, the projection shape of the first protrusion on the horizontal plane is a first U-shaped structure, the opening 306 of the first U-shaped structure faces the second limiting stop 70121, and the second limiting stop 70121 is a limiting stop on one side of the opening 306 of the first U-shaped structure.

[0505] For example, by setting the structure of the first protrusion as a first U-shaped structure, the weight of the second water receiving tray 88 can be reduced without affecting its limiting and stopping function. Furthermore, the second limiting and stopping part 70121 and the opening 306 side of the first U-shaped structure limit and stop, improving the structural rigidity of the first protrusion, so that the second limiting and stopping part 70121 is less likely to deform when the indoor heat exchanger 70 shakes.

[0506] It is understandable that the opening 306 of the first U-shaped structure may not face the second limiting stop 70121, but rather face the side away from the second limiting stop 70121. This enhances the structural strength of the first protrusion and better ensures the limiting stop function.

[0507] Furthermore, a second protrusion 320 is provided on the second water receiving tray 88 (as shown in Figure 65). The second protrusion 320 is located at the bottom of the first plate 7013 and fits against the bottom of the first plate 7013.

[0508] For example, by providing a second protrusion 320 at the bottom of the first plate 7013, the top surface of the second protrusion 320 can contact and fit against the bottom surface of the first plate 7013, which can provide support for the first plate 7013 and help ensure the limiting fit between the first flange and the first protrusion.

[0509] Furthermore, the projection shape of the second protrusion 320 on the horizontal plane is a second U-shaped structure, and the top surface of the second U-shaped structure is in contact with the bottom surface of the first flat plate 7013.

[0510] For example, by setting the structure of the second protrusion 320 as a second U-shaped structure, the weight of the second water receiving tray 88 can be reduced without affecting its supporting function, and the structural strength of the second water receiving tray 88 at the second end plate 7012 can be improved, making it less prone to deformation.

[0511] Therefore, by setting a first protrusion and a second protrusion 320 at a position near the second end plate 7012 on the second water receiving tray 88, so that the first protrusion makes contact with the first flange limiting stop and the second protrusion 320 makes contact with the first flat plate 7013, the limiting fit between the indoor heat exchanger 70 and the second water receiving tray 88 can be effectively improved.

[0512] In some embodiments, referring to Figures 66 and 67, the indoor fan 42 includes an end cap 321 at its top, a third limiting stop 322 is provided on the end cap 321, and a fourth limiting stop 70131 is provided at the end of the second end plate 7012 away from the second water receiving tray 88, with the third limiting stop 322 and the fourth limiting stop 70131 providing limiting stops.

[0513] For example, an end cap 321 is installed on the top of the indoor fan 42 to secure the indoor fan 42.

[0514] For example, the end cap 321 can also be installed and fixed to the top cover 310 on the top of the portable air conditioner 100, which helps to improve the stability of the indoor fan 42.

[0515] For example, in addition to the lower end of the second end plate 7012 being limited and stopped by the second water receiving tray 88, a fourth limiting stop 70131 is provided at the upper end of the second end plate 7012 to cooperate with the third limiting stop 322 on the end cover 321, thereby limiting the top of the indoor heat exchanger 70, better limiting and fixing the indoor heat exchanger 70, and improving the stability of the indoor heat exchanger 70 after installation.

[0516] It should be noted that the end of the second end plate 7012 away from the second water receiving tray 88 has a second flat plate 7014 arranged in the horizontal direction. The second flat plate 7014 has a second flange bent downward to form a fourth limiting stop 70131. The second flange and the third limiting stop 322 limit the stop in the horizontal direction.

[0517] In other words, a second flat plate 7014 bent outward is provided at the upper end of the second end plate 7012. The second flat plate 7014 is provided with a second flange bent downward. The second flange and the third limiting stop 322 on the end cover 321 can limit and fix the top of the indoor heat exchanger 70 in the horizontal direction, so as to prevent the indoor heat exchanger 70 from shaking during transportation.

[0518] In some embodiments, the bottom of the end cap 321 is provided with a downwardly protruding third protrusion forming a third limiting stop 322, which limits and stops the fourth limiting stop 70131 in the horizontal direction.

[0519] The top of the indoor heat exchanger 70 is limited by the third protrusion at the bottom of the end cover 321 and the fourth limiting stop 70131 in the horizontal direction. The structure is simple and easy to install.

[0520] Furthermore, a reinforcing rib 323 is provided on the side of the third protrusion that is away from the fourth limiting stop 70131, and the two ends of the reinforcing rib 323 are respectively connected to the third protrusion and the end cap 321.

[0521] In some embodiments, in order to improve the structural strength of the third protrusion, a reinforcing rib 323 is provided on the side of the third protrusion away from the fourth limiting stop 70131, so that the two ends of the reinforcing rib 323 are respectively connected to the bottom of the third protrusion and the end cap 321, thereby helping to prevent the third protrusion from deforming.

[0522] In some embodiments, as shown in Figures 64 to 67, a plurality of openings 306 are provided on the first plate portion 7015 of the second end plate 7012, and the plurality of openings 306 are configured for the refrigerant pipes of the indoor heat exchanger 70 to pass through. A second limiting stop portion 70121 is provided at the lower end of the first plate portion 7015, and a fourth limiting stop portion 70131 is provided at the upper end of the first plate portion 7015.

[0523] The indoor heat exchanger 70 is fixed by the second limiting stop 70121 and the first limiting stop 319 (i.e. the first protrusion) on the second water receiving tray 88, and the fourth limiting stop 70131 and the third limiting stop 322 (i.e. the third protrusion) on the end cover 321, thereby effectively preventing the indoor heat exchanger 70 from moving.

[0524] For example, for the outdoor heat exchanger 60 of the outdoor air duct assembly 20, in order to prevent the outdoor heat exchanger 60 from moving, similar limiting and stopping structures can be set at both ends of the second end plate 7012 of the outdoor heat exchanger 60 to ensure the stability of the outdoor heat exchanger 60 after installation.

[0525] Therefore, compared to the conventional method of limiting and fixing the indoor heat exchanger 70 to the second water receiving tray 88, this disclosure uses a second limiting stop 70121 at the lower end of the second end plate 7012 and a first limiting stop 319 on the second water receiving tray 88 for limiting and stopping, and a fourth limiting stop 70131 at the upper end of the second end plate 7012 and a third limiting stop 322 on the end cover 321 of the indoor fan 42 for limiting and stopping. This provides better limiting and fixing of the indoor heat exchanger 70, helps to reduce the movement of the indoor heat exchanger 70 inside the portable air conditioner 100 during transportation, and improves the stability of the indoor heat exchanger 70 after installation. The installation method in this embodiment reduces the use of screws, reduces the installation cost of the indoor heat exchanger 70, and improves the ease of installation of the indoor heat exchanger 70.

[0526] In some embodiments, as shown in Figures 74, 79 and 82, the housing 10 includes a second front housing 226. The second front housing 226 is provided with an indoor air outlet 4158. Indoor air enters the housing 10 from the indoor air inlet 11 and flows to the indoor heat exchanger 70. After exchanging heat with the refrigerant at the indoor heat exchanger 70, the indoor air is discharged into the room from the indoor air outlet 4158.

[0527] As shown in Figures 27, 74, and 75, the outer casing 10 also includes a second rear casing 304. The second rear casing 304 is connected to the second front casing 226 to define a first sub-accommodating space 141, a second sub-accommodating space 142, and a third sub-accommodating space 143.

[0528] As shown in Figure 74, the housing 10 also includes a top cover 310. The edge of the top cover 310 extends downward to engage with the top of the second front housing 226 and the second rear housing 304 to seal the top of the housing 10.

[0529] For example, the edge of the top cover 310 extends downward to form a downward-facing cavity with the opening 306 facing down, facilitating fastening. Furthermore, the edge of the top cover 310 fastens to the inside of the second front shell 226 and the second rear shell 304 to ensure the exterior of the outer shell 10 is simple and not easily damaged during transportation.

[0530] As shown in Figures 77 to 79, a rib 228 is provided on the inner sidewall of at least one of the second front shell 226 or the second rear shell 304. The side edge of the top cover 310 overlaps the rib 228. An eleventh snap-fit ​​part 229 is provided on the rib 228. A twelfth snap-fit ​​part 312 is provided at the lower end of the side edge of the top cover 310 to snap-fit ​​with the eleventh snap-fit ​​part 229.

[0531] Taking the second front shell 226 as an example, a rib 228 is provided on the inner side wall of the second front shell 226. When the top cover 310 is fastened to the top of the second front shell 226, the lower end of the side edge of the top cover 310 can overlap the rib 228, which is conducive to fastening and positioning and improves installation efficiency.

[0532] By engaging the eleventh snap-fit ​​portion 229 on the rib 228 with the twelfth snap-fit ​​portion 312 on the inner side wall of the second front shell 226, on the one hand, installation is convenient and the connection reliability between the top cover 310 and the second front shell 226 is guaranteed; on the other hand, the use of fasteners is reduced, thereby reducing the installation cost of the outer shell 10 and improving the ease of installation of the outer shell 10.

[0533] For example, a rib 228 is provided on the inner side wall of the second rear shell 304 so that the eleventh snap-fit ​​portion 229 on the rib 228 snaps into the twelfth snap-fit ​​portion 312 on the inner side wall of the second rear shell 304, thereby achieving a fixed connection between the top cover 310 and the second rear shell 304.

[0534] Compared to the usual practice of providing mounting holes 8071 on the top cover 310, corresponding mounting holes 8071 are provided on the housing to fix the top cover 310 to the top of the housing by passing fasteners through the two mounting holes 8071. In this disclosure, the connection and fixation between at least one of the second front housing 226 or the second rear housing 304 and the top cover 310 is achieved by engaging the eleventh snap-fit ​​portion 229 on the rib 228 with the twelfth snap-fit ​​portion 312 on the inner sidewall of the second front housing 226.

[0535] Thus, by overlapping the lower edge of the top cover 310 with the rib 228, and by engaging the eleventh snap-fit ​​portion 229 on the rib 228 with the twelfth snap-fit ​​portion 312 on the inner sidewall of at least one of the second front shell 226 or the second rear shell 304, the connection and fixation between at least one of the second front shell 226 or the second rear shell 304 and the top cover 310 is achieved. Furthermore, this effectively reduces the use of fasteners, thereby reducing the installation cost of the outer casing 10 and improving the ease of installation of the outer casing 10.

[0536] In some embodiments, as shown in Figures 74 to 81, one end of the rib 228 is provided with a first slot to form an eleventh snap-fit ​​portion 229, and a convex plate 311 is provided at the lower end of the side edge of the top cover 310. The convex plate 311 is provided with a second slot facing the first slot, and the convex plate 311 is snapped onto the first slot through the second slot.

[0537] It should be noted that after the side edge of the top cover 310 overlaps the rib 228, it moves toward one side of the first latch so that the second latch of the convex plate 311 engages with the first latch, thereby achieving the engagement of the first latch and the second latch.

[0538] In the embodiments of this disclosure, ribs 228 are provided on the inner sidewall of the second front shell 226 and the inner sidewall of the second rear shell 304. When the top cover 310 is connected to the second front shell 226 and the second rear shell 304, the second front shell 226 moves toward the top cover 310 so that the ribs 228 on the inner sidewall of the second front shell 226 move along the side edge of the top cover 310, thereby causing the first snap on the rib 228 of the second front shell 226 to engage in the second snap in the protrusion 311 of the top cover 310.

[0539] Similarly, the second rear shell 304 moves toward the top cover 310 so that the rib 228 on the inner side wall of the second rear shell 304 moves along the side edge of the top cover 310, thereby making the first slot on the rib 228 of the second rear shell 304 engage with the second slot of the convex plate 311 of the top cover 310.

[0540] For example, a protruding plate 311 can be provided on the side edge of the top cover 310. A second latch is provided on the side of the protruding plate 311 facing the second front shell 226 and the side facing the second rear shell 304, so that the two second latches can be engaged with the first latch of the protruding rib 228 of the second front shell 226 and the first latch of the protruding rib 228 of the second rear shell 304, respectively.

[0541] For example, two protrusions 311 can be provided on the side edge of the top cover 310. The two protrusions 311 are respectively provided with a second snap-fit ​​on the opposite side for engaging with the second front shell 226 and the second rear shell 304.

[0542] Furthermore, the rib 228 extends back and forth on the inner sidewall of at least one of the second front shell 226 or the second rear shell 304 and is inclined, and the side edge of the top cover 310 is inclined and overlaps with the rib 228.

[0543] The inclined ribs 228 overlap with the corresponding side edge of the top cover 310 to provide positioning and support.

[0544] In some embodiments, the ribs 228 on the inner sidewall of the second front shell 226 and the ribs 228 on the inner sidewall of the second rear shell 304 are inclined relative to each other.

[0545] For example, the ribs 228 on the inner wall of the second front shell 226 are inclined downward from the front end to the rear end, and the ribs 228 on the inner wall of the second rear shell 304 are inclined upward from the front end to the rear end, which can prevent the top cover 310 from swaying back and forth when there is an installation gap.

[0546] In some embodiments, as shown in Figures 74 to 81, a support protrusion is provided on the inner wall of the second front shell 226 on its front side, and the front edge of the top cover 310 overlaps with the support protrusion.

[0547] It should be noted that the structure and function of the supporting protrusion are similar to those of the second protrusion 320 in Figure 76, and will not be described again here.

[0548] The top cover 310 can be stably fastened to the second front cover 226 by the support protrusion on the front side of the second front cover 226 overlapping with the front edge of the top cover 310.

[0549] For example, as shown in Figures 77 to 79, the second front shell 226 has a thirteenth snap-fit ​​part 303 on its inner wall at its front side, and the top cover 310 has a fourteenth snap-fit ​​part 316 on its front edge that snaps into the thirteenth snap-fit ​​part 303.

[0550] The engagement of the thirteenth snap-fit ​​part 303 and the fourteenth snap-fit ​​part 316 facilitates the connection and fixation between the top cover 310 and the second front shell 226. Furthermore, it effectively reduces the use of fasteners, thereby reducing the installation cost of the shell 10 and improving the ease of installation.

[0551] Similarly, as shown in Figures 80 and 81, the second rear shell 304 has a fifteenth snap-fit ​​portion 309 on its rear inner wall, and the top cover 310 has a sixteenth snap-fit ​​portion 317 on its rear edge that engages with the fifteenth snap-fit ​​portion 309.

[0552] The engagement of the fifteenth snap-fit ​​portion 309 and the sixteenth snap-fit ​​portion 317 facilitates the connection and fixation between the top cover 310 and the second rear shell 304. Furthermore, it effectively reduces the use of fasteners, thereby reducing the installation cost of the outer shell 10 and improving the ease of installation.

[0553] For example, the thirteenth snap-fit ​​part 303 and the fourteenth snap-fit ​​part 316 can be a combination of a snap fastener and a snap hole.

[0554] Furthermore, the second front shell 226 and the second rear shell 304 can be connected by fasteners or by a snap-fit ​​method. The snap-fit ​​method involves first positioning and fastening the shell, and then securing it with fasteners.

[0555] In some embodiments, as shown in FIG80, a first fixing plate 313 is provided on the inner top wall of the top cover 310 at its front edge. The two ends of the first fixing plate 313 are respectively connected to the two sides of the front edge of the top cover 310. A second notch 314 is provided on the front edge of the top cover 310, and an avoidance space 315 is formed between the front edge of the top cover 310 and the first fixing plate 313.

[0556] By forming a clearance space 315 between the front edge of the top cover 310 and the first fixing plate 313, the gap between the second front shell 226 and the top cover 310 caused by the deformation of the front side can be avoided, thereby improving the connection and sealing between the second front shell 226 and the top cover 310.

[0557] For example, the first fixing plate 313 and the top cover 310 are integrally formed, which can ensure structural strength and improve the ease of installation of the outer shell 10.

[0558] For example, the first fixing plate 313 and the top cover 310 are detachably connected, which facilitates the individual maintenance and replacement of the first fixing plate 313 and the top cover 310.

[0559] In some embodiments, as shown in FIG74, the second front housing 226 includes a first front panel 300. The second front housing 226 also includes a side panel 301.

[0560] For example, the first front panel 300 and the side panel 301 can be integrally molded, which facilitates installation and has a simple appearance.

[0561] For example, the first front panel 300 and the side panel 301 are detachably connected, which facilitates the individual maintenance and replacement of the first front panel 300 and the side panel 301.

[0562] For example, as shown in Figure 75, a first groove 302 extending along the height direction is provided at the connection between the first front panel 300 and the side panel 301. The first groove 302 forms a planar structure between the side of the first front panel 300 connected to the other side of the side panel 301.

[0563] In other words, the connection between the first front panel 300 and the side panel 301 is set as a sloping structure. Since the sloping surface does not extend through both ends of the first front panel 300 and the side panel 301, a recessed structure of the first groove 302 is formed at the connection between the first front panel 300 and the side panel 301.

[0564] Without affecting the installation of internal components of the housing 10, setting the connection between the first front panel 300 and the side panel 301 as an inclined first groove 302 can enhance the appearance design of the housing 10. Furthermore, the first groove 302 does not extend through both ends of the housing 10, so that the first groove 302 forms an angular design structure with the first front panel 300 and the side panel 301, further enhancing the appearance design.

[0565] The two sides of the groove are connected to the first front panel 300 and the side panel 301 by a rounded transition, and the two ends of the groove form sidewalls with an arc structure.

[0566] For example, the groove is connected to the first front panel 300 with an arc transition, the groove is connected to the side panel 301 with an arc transition, and the two ends of the groove are formed with arc-shaped structures to avoid bumps and damage to the second front shell 226 and to prevent potential damage to the user.

[0567] In some embodiments, as shown in FIG75, a second recessed groove 305 is provided on the upper rear side of the second rear shell 304. The second groove 305 extends through the width direction. The bottom wall of the second groove 305 is connected to its side wall near the upper part of the second rear shell 304 by an arc transition. An opening 306 is provided on the side wall of the second groove 305 near the lower part of the second rear shell 304.

[0568] The second rear shell 304 has an upper part and a lower part, as shown in FIG27. The upper part of the second rear shell 304 forms a third sub-accommodating space 143, and the lower part of the second rear shell 304 forms a first sub-accommodating space 141 and a second sub-accommodating space 142.

[0569] For example, the rear side of the upper part of the second rear shell 304 is recessed forward to form a second groove 305, which extends through the width of the outer shell 10. The second groove 305 is configured to install the outdoor air intake duct 43 for heat exchange with the outdoor space.

[0570] The bottom wall of the second groove 305 is the front side shown in Figure 75, and the side walls of the second groove 305 are the upper and lower sides shown in Figure 75.

[0571] In some embodiments, the bottom wall of the second groove 305 is connected to its lower side wall by an arc transition, which not only improves the appearance but also prevents bumps and scratches when installing the outdoor air inlet pipe 43 and the outdoor air outlet pipe 44.

[0572] For example, the second groove 305 has an opening 306 on the side wall near the lower part of the second rear shell 304. The opening 306 is configured to connect one end of the outdoor air inlet pipe 43 and the outdoor air outlet pipe 44 to the outdoor air duct so as to allow air to circulate with the outdoor air duct.

[0573] Furthermore, a third recessed groove 307 is provided on the bottom wall of the second groove 305, and a ventilation window 308 is provided at the bottom of the third groove 307. In other words, a third groove 307 is provided on the front side of the second groove 305, and its ventilation window 308 can be used for heat dissipation.

[0574] In some embodiments, as shown in FIG75, heat dissipation holes are provided on both sides of the lower part of the second rear shell 304 so that the heat generated by the electronic control box 50 can be dissipated in a timely manner through the heat dissipation holes, thereby improving the service life of the electronic control box 50.

[0575] In some embodiments, as shown in Figures 79 and 80, a plurality of stiffening plates 318 are provided on the inner top wall of the top cover 310. The plurality of stiffening plates 318 extend along at least one of the thickness direction or the width direction and are arranged at intervals.

[0576] It should be noted that by providing multiple stiffening plates 318 on the inner top wall of the top cover 310, the structural strength of the top cover 310 can be enhanced. Furthermore, mounting parts such as mounting holes 8071 and mounting posts 814 can be provided on the stiffening plates 318 to connect with functional components inside the outer casing 10.

[0577] In some embodiments, three sets of stiffening plates 318 are provided on the inner top wall of the top cover 310, and each set of stiffening plates 318 includes two parallel stiffening plates 318.

[0578] For example, one set of stiffeners 318 is spaced apart along the width direction of the outer shell 10, and the other two sets of stiffeners 318 are spaced apart along the thickness direction of the outer shell 10. Furthermore, the set of stiffeners 318 spaced apart along the width direction of the outer shell 10 and the two sets of stiffeners 318 spaced apart along the thickness direction of the outer shell 10 are interleaved, thereby enhancing the structural strength of the top of the outer shell 10.

[0579] In some embodiments, as shown in Figures 70 to 74, the portable air conditioner 100 further includes a second top plate 324, which is disposed above the indoor air duct assembly 40. The portable air conditioner 100 also includes a display component 330, which is disposed above the indoor air duct assembly 40 and fixedly connected to the second top plate 324. That is, the display component 330 is fixedly installed by connecting to the second top plate 324. Since the display component 330 is disposed above the indoor air duct assembly 40, it is also disposed above the portable air conditioner 100, facilitating real-time monitoring of the portable air conditioner 100's operating parameters by the user.

[0580] In some embodiments, the portable air conditioner 100 further includes a first fastener that extends in the vertical direction and is fixedly connected to the second top plate 324 after passing through the display assembly 330.

[0581] It should be noted that the first fastener passes through the display component 330 and the second top plate 324 from bottom to top and is fixedly connected to it, thereby fixing the display component 330 onto the second top plate 324 and completing the initial installation of the display component 330.

[0582] The front side of the display component 330 has an installation space configured to mount a circuit board. The rear side of the display component 330 is fixedly connected to the second top plate 324, which helps to avoid interference between the installation position and the circuit board.

[0583] Thus, the first fastener passes through the display component 330 and the second top plate 324 from bottom to top and is fixedly connected to fix the display component 330 on the second top plate 324, which facilitates the wiring of the circuit board and helps to avoid interference with the circuit board.

[0584] In some embodiments, as shown in Figures 69 to 73, a first mounting boss 331 is provided on the side of the display component 330 facing the indoor heat exchanger 70. The first mounting boss 331 protrudes towards the indoor heat exchanger 70, and a first fastener passes through the first mounting boss 331 in the vertical direction and is fixedly connected to the second top plate 324.

[0585] It should be noted that the first mounting boss 331 is located on the side of the display component 330 facing the indoor heat exchanger 70. The first mounting boss 331 protrudes from the side facing the indoor heat exchanger 70, providing a mounting point for the fixed connection of the display component 330 and the second top plate 324.

[0586] The first fastener is connected to the first mounting boss 331 and the second top plate 324 to fix the display component 330 on the second top plate 324, thereby achieving the initial installation of the display component 330.

[0587] For example, the first mounting boss 331 is located on the rear side of the display assembly 330 to prevent damage to the circuit board when the first fastener passes through the first mounting boss 331.

[0588] For example, there can be two first mounting bosses 331, which are spaced apart in the left and right direction to increase the connection strength between the display component 330 and the second top plate 324.

[0589] In some embodiments, as shown in FIG69, a first mounting member 325 is provided on the first mounting boss 331, and a second mounting part 224 is provided on the second top plate 324. The first fastener passes through the first mounting member 325 and is fixedly connected to the second mounting part 224.

[0590] For example, the positions of the first mounting member 325 and the second mounting part 224 correspond to each other, and the first fastener is fixedly connected to the second mounting part 224 through the first mounting member 325, thereby fixing the display component 330 on the second top plate 324 and initially completing the installation of the display component 330.

[0591] In some embodiments, as shown in FIG69, the first mounting boss 331 includes a second fixing plate 332. As shown in FIG73, the first mounting boss 331 includes two fourth side plates 333. The two fourth side plates 333 are disposed on both sides of the second fixing plate 332 in the left-right direction, and a second cavity 335 for a first fastener to pass through is formed between the two fourth side plates 333 and the second fixing plate 332. A first mounting member 325 is disposed on the second fixing plate 332.

[0592] For example, two fourth side plates 333 extend along the height direction and are spaced apart in the left-right direction. A second fixing plate 332 is disposed between the two fourth side plates 333, forming a second chamber 335 between the two fourth side plates 333 and the second fixing plate 332. The second chamber 335 provides installation space for the first fastener. The second fixing plate 332 is provided with a first mounting member 325, and the first fastener passes through the second chamber 335 and the first mounting member 325 to be fixedly connected to the second top plate 324, completing the initial installation of the display assembly 330.

[0593] For example, the first mounting boss 331 is provided with a first limiting groove 334 on the side facing the second top plate 324, and the second top plate 324 is provided with a third limiting protrusion 326 on the side facing the first mounting boss 331. The third limiting protrusion 326 and the first limiting groove 334 are matched for limiting.

[0594] It should be noted that the third limiting protrusion 326 is adapted to the first limiting groove 334. On the one hand, before the display component 330 is installed, the third limiting protrusion 326 and the first limiting groove 334 play a positioning role, improving installation efficiency. On the other hand, after the display component 330 is installed, the third limiting protrusion 326 and the first limiting groove 334 play a limiting role, preventing the display component 330 from shaking.

[0595] In some embodiments, as shown in Figures 70 to 73, a second clearance groove is provided on the second top plate 324. The second clearance groove is located on the front side of the second top plate 324 and faces the display component 330, and the display component 330 is disposed within the second clearance groove. Specifically, the second clearance groove is located on the front side of the second top plate 324, and the position of the second clearance groove corresponds to that of the display component 330. The upper side of the display component 330 is located within the second clearance groove, thereby improving space utilization.

[0596] It should be noted that the structure and function of the second clearance groove are similar to those of the first clearance groove 2421 in Figure 38.

[0597] In some embodiments, as shown in Figures 70 and 71, the portable air conditioner 100 further includes two support beams 93, which are spaced apart in the left-right direction and extend in the up-down direction, with their upper ends fixedly connected to the upper ends of the indoor air duct component 41. The second top plate 324 is connected to the two support beams 93.

[0598] It should be noted that the two support beams 93 are respectively set on both sides of the indoor air duct component 41. This can support both sides of the indoor air duct component 41 and fix the indoor air duct component 41 above the outdoor heat exchanger 60, so as to ensure the structural stability of the indoor air duct component 41 in the portable air conditioner, and thus ensure the reliability of the portable air conditioner 100.

[0599] In some embodiments, as shown in Figures 69 to 73, the portable air conditioner 100 further includes a chassis 16, which is disposed below the outdoor duct assembly 20. The compressor 30 and the electrical control box 50 are disposed above the chassis 16. A support beam 93 extends vertically, and its two ends in the height direction are connected to the second top plate 324 and the chassis 16, respectively, to ensure the structural stability of the support beam 93. The support beam 93 is connected to the indoor duct component 41, so that the support beam 93 can simultaneously support the second top plate 324 and the indoor duct component 41, ensuring the structural stability of the indoor duct component 41 in the portable air conditioner 100.

[0600] In some embodiments, as shown in FIG18, the support beam 93 includes a first support section 931, which extends in the vertical direction and is connected at its lower end to the chassis 16. This allows the support beam 93 to be fixed on the chassis 16, thereby providing reliable support for the indoor air duct component 41.

[0601] As shown in Figure 18, the support beam 93 also includes a second support section 932, which is connected to the upper end of the first support section 931 so that the second support section 932 is fixed on the first support section 931. The second support section 932 is also connected to the indoor air duct component 41 and the second top plate 324. This arrangement allows the second support section 932 to provide reliable support for the indoor air duct component 41 and the second top plate 324, preventing the indoor air duct component 41 from shaking in the portable air conditioner 100 and ensuring the structural stability of the indoor air duct component 41, thereby ensuring the structural reliability of the portable air conditioner 100.

[0602] In some embodiments, as shown in Figures 58, 70, and 71, the indoor air duct assembly 40 further includes a second fastener extending in the front-rear direction. The second fastener passes through the lower side of the display assembly 330 and is fixedly connected to the indoor air duct component 41. That is, the display assembly 330 and the indoor air duct component 41 are fixedly connected by the second fastener. The lower side of the display assembly 330 abuts against the indoor air duct component 41, and the second fastener passes through the lower end of the display assembly 330 and is fixedly connected to the indoor air duct component 41, thereby improving the installation stability of the display assembly 330.

[0603] In some embodiments, as shown in Figures 72 and 73, a second mounting boss 336 is provided on the lower side of the display component 330, a third connecting portion is provided on the second mounting boss 336, a fourth connecting portion 418 is provided on the indoor air duct component 41, and a second fastener passes through the third connecting portion and connects to the fourth connecting portion 418.

[0604] For example, the second mounting boss 336 is located on the lower side of the display component 330, and provides a mounting point for the display component 330. The third connecting portion on the second mounting boss 336 corresponds to the fourth connecting portion 418 on the indoor air duct component 41. The second fastener passes through the third mounting portion and is fixedly connected to the fourth mounting portion, so that the display component 330 and the indoor air duct component 41 are fixedly connected, further improving the installation stability of the display component 330.

[0605] The mounting space between the second mounting boss 336 and the display component 330 is set to avoid interference between the second mounting boss 336 and the circuit boards in the mounting space.

[0606] In some embodiments, as shown in FIG72, the portable air conditioner 100 further includes a second front panel 328, which is disposed outside the indoor air duct assembly 40 and the outdoor air duct assembly 20 and is fixedly connected to the second top panel 324. Specifically, the second front panel 328 is disposed on the front side of the portable air conditioner 100, the second front panel 328 is fixedly connected to the second top panel 324, and the second front panel 328 covers the front side of the display assembly 330.

[0607] In some embodiments, as shown in FIG72, a fourth limiting protrusion 329 is provided on the second front panel 328, and a second limiting groove 338 is provided on the display component 330. The fourth limiting protrusion 329 and the second limiting groove 338 engage in a limiting cooperation. That is, the fourth limiting protrusion 329 and the second limiting groove 338 engage in a limiting cooperation to limit the display component 330, preventing the display component 330 from shifting and affecting the user's interaction with the portable air conditioner 100.

[0608] In some embodiments, as shown in Figures 85 and 86, the compressor 30 and the control box 50 are spaced apart in the horizontal direction of the accommodating space 14, which helps to avoid interference between the compressor 30 and the control box 50.

[0609] In some embodiments, as shown in Figures 85 to 90, the outdoor heat exchanger 60, indoor heat exchanger 70, outdoor air duct assembly 20, indoor air duct assembly 40, air inlet pipe 43, and air outlet pipe 44 are arranged above the compressor 30 and the electrical control box 50. In this way, by making reasonable use of the internal space of the portable air conditioner 100, the compressor 30 and the electrical control box 50 are separated from the outdoor heat exchanger 60, indoor heat exchanger 70, outdoor air duct assembly 20, indoor air duct assembly 40, air inlet pipe 43, and air outlet pipe 44, respectively, forming an independent module. This not only facilitates maintenance and replacement but also improves the heat exchange efficiency of the portable air conditioner 100.

[0610] For example, the outdoor heat exchanger 60 and the outdoor air duct assembly 20 are located above the compressor 30 and the electrical control box 50, and the outdoor heat exchanger 60 and the outdoor air duct assembly 20 are arranged in the horizontal direction of the accommodating space 14. The air inlet pipe 43 and the air outlet pipe 44 are located above the outdoor heat exchanger 60 and the outdoor air duct assembly 20, and the air inlet pipe 43 and the air outlet pipe 44 are arranged in the horizontal direction of the accommodating space 14. The indoor heat exchanger 70 and the indoor air duct assembly 40 are located above the air inlet pipe 43 and the air outlet pipe 44, and the indoor heat exchanger 70 and the indoor air duct assembly 40 are arranged in the horizontal direction of the accommodating space 14.

[0611] It should be noted that the outdoor heat exchanger 60 and the outdoor air duct assembly 20 are arranged horizontally in the accommodating space 14, which can accelerate the air delivery speed of the outdoor heat exchanger 60, thereby improving the heat exchange efficiency of the outdoor heat exchanger 60. Furthermore, the horizontal arrangement of the outdoor heat exchanger 60 and the outdoor air duct assembly 20 in the accommodating space 14 can reduce the distance between them and increase the height of the portable air conditioner 100, thereby raising the center of gravity of the portable air conditioner 100 and ensuring greater stability during operation.

[0612] For example, the air inlet duct 43 and air outlet duct 44 are positioned above the outdoor heat exchanger 60 and the outdoor air duct assembly 20. The placement of the air inlet duct 43 increases the air intake volume and velocity, and also expands the air intake range. The placement of the air outlet duct 44 increases the air output volume and velocity, and also expands the air output range, thereby improving the heat exchange efficiency of the portable air conditioner 100. This configuration of the portable air conditioner 100 effectively conceals the air inlet duct 43 and air outlet duct 44. When the portable air conditioner 100 is not in operation, its overall size is smaller, and there is no need to separately store the air inlet duct 43 and air outlet duct 44.

[0613] Furthermore, the indoor heat exchanger 70 and the indoor air duct assembly 40 are disposed above the air inlet duct 43 and the air outlet duct 44, and the indoor heat exchanger 70 and the second heat exchange assembly are arranged in the horizontal direction of the accommodating space 14.

[0614] For example, the indoor heat exchanger 70 and the indoor air duct assembly 40 are arranged in the horizontal direction of the accommodating space 14. The indoor air duct assembly 40 can accelerate the air supply speed of the indoor heat exchanger 70, thereby improving the heat exchange efficiency of the indoor heat exchanger 70. It can also reduce the distance between the indoor heat exchanger 70 and the indoor air duct assembly 40, and increase the height of the portable air conditioner 100, thereby raising the center of gravity of the portable air conditioner 100 and ensuring that the portable air conditioner 100 is more stable during operation.

[0615] In this way, the compressor 30 and the electrical control box 50 are located at the bottom layer of the portable air conditioner 100, the outdoor heat exchanger 60 and the outdoor air duct assembly 20 are located at the second layer of the portable air conditioner 100, the air inlet pipe 43 and the air outlet pipe 44 are located at the third layer of the portable air conditioner 100, and the indoor heat exchanger 70 and the indoor air duct assembly 40 are located at the top layer of the portable air conditioner 100, that is, the fourth layer. In this way, a multi-layer distribution can be achieved inside the portable air conditioner 100, which has the advantages of hierarchical design. It can raise the position of the air outlet 12 of the portable air conditioner 100, so that the air outlet area is higher than that of the traditional portable air conditioner 100, and the air outlet of the indoor air duct assembly 40 can be better directed to the user.

[0616] Therefore, the portable air conditioner 100 can not only achieve multi-layer distribution, but also raise the position of the air outlet 12 of the portable air conditioner 100, so that the air outlet of the indoor air duct assembly 40 can blow better towards the user.

[0617] As shown in Figure 86, the difference between this embodiment and the above embodiment is that the outdoor heat exchanger 60 and the compressor 30 are arranged opposite to each other, and the outdoor heat exchanger 60 is located above (directly above) the compressor 30. In this way, the corresponding arrangement of the outdoor heat exchanger 60 and the compressor 30 can shorten the heat exchange distance between the outdoor heat exchanger 60 and the compressor 30, thereby reducing the heat exchange time between the outdoor heat exchanger 60 and the compressor 30 and improving the heat exchange efficiency between the outdoor heat exchanger 60 and the compressor 30.

[0618] According to some embodiments of this disclosure, as shown in Figures 83 to 85, a second water receiving tray 88 is disposed above the air inlet pipe 43 and the air outlet pipe 44, and an indoor heat exchanger 70 and an indoor air duct assembly 40 are disposed above the second water receiving tray 88. This can isolate the air inlet pipe 43, the air outlet pipe 44, the indoor heat exchanger 70, and the indoor air duct assembly 40, thereby avoiding mutual interference.

[0619] For example, the compressor 30 and the electrical control box 50 are located on the bottom layer, the outdoor heat exchanger 60 and the outdoor air duct assembly 20 are located on the second layer, the air inlet pipe 43 and the air outlet pipe 44 are located on the third layer, and the indoor heat exchanger 70 and the indoor air duct assembly 40 are located on the fourth layer, thus forming a four-layer structure.

[0620] It should be noted that the second water tray 88 also serves to store water, allowing the condensate produced by the indoor heat exchanger 70 to flow to the second water tray 88. This prevents the condensate produced by the indoor heat exchanger 70 from overflowing and also prevents the condensate produced by the indoor heat exchanger 70 from affecting the safety of the internal circuit of the portable air conditioner 100, thus avoiding short circuits.

[0621] In some embodiments, the air inlet pipe 43 and the air outlet pipe 44 are movably disposed on the housing 10, thereby adjusting the length of the air inlet pipe 43 and the air outlet pipe 44 extending out of the receiving space 14 by means of movement.

[0622] It should be noted that since the air inlet pipe 43 and the air outlet pipe 44 can move relative to the outer casing 10, it is convenient to adjust the position of the air inlet pipe 43 and the air outlet pipe 44 in the receiving space 14, and it is also possible to further adjust the length of the air inlet pipe 43 and the air outlet pipe 44 extending out of the receiving space 14. The length extending out of the receiving space 14 can be set to be longer or shorter, and it is also convenient to connect with the outdoor air, which has good adaptability.

[0623] According to some embodiments of this disclosure, as shown in FIG85, at least one of the air inlet pipe 43 and the air outlet pipe 44 is provided with a seventeenth snap-fit ​​portion 441, and at least one of the housing 10 and the outdoor air duct assembly 20 is provided with a second snap-fit ​​portion 241. When at least one of the air inlet pipe 43 and the air outlet pipe 44 extends to its maximum length relative to the housing 10 through the receiving space 14, the seventeenth snap-fit ​​portion 441 and the second snap-fit ​​portion 241 engage. Thus, when the air inlet pipe 43 is provided with the seventeenth snap-fit ​​portion 441, at least one of the housing 10 and the outdoor air duct assembly 20 is correspondingly provided with the second snap-fit ​​portion 241. The seventeenth snap-fit ​​portion 441 may be provided with a snap-fit ​​protrusion, and the second snap-fit ​​portion 241 may be provided with a snap-fit ​​groove. The snap-fit ​​protrusion and the snap-fit ​​groove engage, thereby making the engagement more secure.

[0624] Alternatively, at least one of the air inlet pipe 43 and the air outlet pipe 44 is provided with a nineteenth snap-fit ​​portion 443, and at least one of the housing 10 and the outdoor air duct assembly 20 is provided with a twentieth snap-fit ​​portion. When at least one of the air inlet pipe 43 and the air outlet pipe 44 extends out of the receiving space 14 to the minimum length relative to the housing 10, the nineteenth snap-fit ​​portion 443 engages with the twentieth snap-fit ​​portion, thereby making the engagement more secure.

[0625] According to some embodiments of this disclosure, as shown in Figures 84 to 86, the air inlet 11 corresponds to the indoor heat exchanger 70, and the air outlet 12 corresponds to the outlet 532 of the indoor air duct assembly 40, with the air outlet 12 extending in the vertical direction.

[0626] It should be noted that the air inlet 11 corresponds to the indoor heat exchanger 70, which increases the contact area between the air inlet 11 and the indoor heat exchanger 70, thereby improving the heat exchange efficiency of the indoor heat exchanger 70, i.e., improving the heat exchange efficiency of the evaporator. The air outlet 12 corresponds to the outlet 532 of the indoor air duct assembly 40, which can accelerate the heat exchange speed of the indoor heat exchanger 70, thereby further improving the heat exchange efficiency of the portable air conditioner 100.

[0627] In some embodiments, the air outlet 12 extends in the vertical direction, so that the air outlet 12 can form a vertical air outlet, which means air outlet in the vertical direction. This can increase the range of vertical air supply and expand the air supply area, thereby increasing the air supply volume of the portable air conditioner 100.

[0628] According to some embodiments of this disclosure, as shown in Figures 91 and 92, the difference from the above embodiments is that the air guide plate 90 has an upper rotating shaft 91 and a lower rotating shaft 92, the upper end of the air duct component is provided with an upper rotating hole 411, the second water receiving tray 88 is provided with a mounting boss 821, the lower end of the air guide plate 90 is provided with a lower rotating hole 822, the upper rotating shaft 91 is rotatably disposed in the upper rotating hole 411, and the lower rotating shaft 92 is rotatably disposed in the lower rotating hole 822.

[0629] For example, the air guide plate 90 has an upper rotating shaft 91. Correspondingly, the upper end of the air duct component is provided with an upper rotating hole 411. The upper rotating shaft 91 can be inserted into the upper rotating hole 411 for connection and cooperation, so that the upper rotating shaft 91 of the air guide plate 90 can rotate around the upper rotating hole 411 provided at the upper end of the air duct component.

[0630] Furthermore, the second water receiving tray 88 is provided with a mounting boss 821, on which a lower rotating shaft 92 is provided. The mounting boss 821 can support the lower rotating shaft 92 and also increase the contact area between the mounting boss 821 and the lower rotating shaft 92, thereby making the lower rotating shaft 92 and the mounting boss 821 fit together more stably.

[0631] Some embodiments of this disclosure also provide a duct fixing plate 100A, which can be applied to the portable air conditioner and portable air conditioner assembly provided in any of the above or below embodiments.

[0632] As shown in Figures 93 and 94, in some embodiments of this disclosure, the duct fixing plate 100A is configured to be installed on a window and used to close the window, and the duct assembly of the portable air conditioner is fixed on the duct fixing plate 100A.

[0633] For example, a duct fixing plate 100A is installed on the window, and the duct fixing plate 100A can be installed on the inner wall of the window. By installing the duct fixing plate 100A, the gap between the duct assembly of the portable air conditioner and the inner wall of the window can be filled, thereby closing the window and achieving environmental isolation between the indoor and outdoor environments.

[0634] In some embodiments, as shown in Figures 93 to 96, the duct fixing plate 100A includes: a first sub-fixing plate 710 and a second sub-fixing plate 720, the second sub-fixing plate 720 and the first sub-fixing plate 710 cooperating with each other, and the second sub-fixing plate 720 and the first sub-fixing plate 710 being slidable relative to each other, thereby allowing the dimensions of the first sub-fixing plate 710 and the second sub-fixing plate 720 in the left-right direction (such as the first direction) to be adjusted.

[0635] In some embodiments, as shown in Figures 93, 94, and 97, the duct fixing plate 100A further includes an adjustment assembly 400. The adjustment assembly 400 is disposed on the first sub-fixing plate 710, and the adjustment assembly 400 selectively engages with the second sub-fixing plate 720.

[0636] For example, when the first sub-fixed plate 710 moves to a first predetermined position in the left-right direction relative to the second sub-fixed plate 720, the adjusting component 400 engages with the second sub-fixed plate 720. When the first sub-fixed plate 710 moves to a second predetermined position in the left-right direction relative to the second sub-fixed plate 720, the adjusting component 400 disengages from the second sub-fixed plate 720.

[0637] In some embodiments, one of the first sub-fixing plate 710 and the second sub-fixing plate 720 is provided with a ventilation section 714, and one end of the air duct assembly of the portable air conditioner is connected to the ventilation section 714. For example, the ventilation section 714 may be configured as a vent.

[0638] For example, one end of the duct assembly of the portable air conditioner can be fixed at the ventilation section 714, and the ventilation section 714 enables communication between the outdoor unit and the outdoor unit of the portable air conditioner, so that outside air can enter the outdoor unit for heat exchange.

[0639] In some embodiments, the shape of the ventilation section 714 is adapted to the shape of the duct assembly to achieve fixation at one end of the duct assembly.

[0640] In some embodiments, as shown in FIG94 and FIGS97-99, the adjustment assembly 400 includes a locking member 410. The locking member 410 is used for locking engagement with the second sub-fixed plate 720.

[0641] In some embodiments, the adjustment assembly 400 further includes a drive member 420. The drive member 420 is used to drive the locking member 410 to move in the left-right direction, thereby adjusting the dimensions of the first sub-fixed plate 710 and the second sub-fixed plate 720 in the left-right direction, so that the duct fixing plate 100A can be adapted to windows of different sizes.

[0642] In some embodiments, as shown in FIG96, the second sub-fixing plate 720 is provided with a plurality of first locking portions 722 arranged in the left-right direction.

[0643] In some embodiments, as shown in FIG98 and FIG100, the locking member 410 is provided with a second locking portion 4110, which engages with any one of a plurality of first locking portions 722.

[0644] For example, the second sub-fixing plate 720 includes a plurality of first locking parts 722, and the locking member 410 includes a second locking part 4110. Since the locking member 410 is provided on the first sub-fixing plate 710, when the second locking part 4110 and any one of the first locking parts 722 are locked together, the first sub-fixing plate 710 and the second sub-fixing plate 720 can lock each other, thereby allowing the duct fixing plate 100A to be fixed to the window.

[0645] Furthermore, since the multiple first locking portions 722 on the second sub-fixing plate 720 are spaced apart in the left and right direction, when the second locking portion 4110 is locked with different first locking portions 722, the relative positions of the first sub-fixing plate 710 and the second sub-fixing plate 720 are different, thereby making the duct fixing plate 100A different in the left and right direction, and thus making the duct fixing plate 100A adaptable to windows of different sizes.

[0646] In some embodiments, as shown in Figures 99 and 101, the drive member 420 is provided with a drive part 421 and a cam part 422, and the drive part 421 and the cam part 422 are connected to each other.

[0647] The cam portion 422 abuts against the side of the locking member 410 opposite to the second locking portion 4110 to drive the locking member 410 to move in the left-right direction. For example, the cam portion 422 is disposed inside the locking member 410 and abuts against the inner wall (such as the inner bottom wall and inner side wall) of the locking member 410.

[0648] In this way, when the cam portion 422 rotates, the radius of the cam portion 422 near the locking member 410 will increase (for example, the radius of the cam portion 422 will increase in the left and right direction), thereby the cam portion 422 will apply a force to the inner wall of the locking member 410, so that the cam portion 422 can drive the locking member 410 to move in the left and right direction, thereby adjusting the distance between the first sub-fixed plate 710 and the second sub-fixed plate 720.

[0649] In addition, a drive unit 421 is connected to the cam portion 422, which can drive the cam portion 422 to rotate. For example, the drive unit 421 can be a lever, or other structures that can drive the cam portion 422 to rotate.

[0650] In some embodiments, the positional relationship between the driving member 420 and the locking member 410 is adjusted as a fine adjustment. For example, the first sub-fixed plate 710 and the second sub-fixed plate 720 are first roughly locked together by the first locking part 722 and the second locking part 4110, and then the first sub-fixed plate 710 and the second sub-fixed plate 720 are finely adjusted by the adjusting component 400. In this way, the stepless adjustment between the first sub-fixed plate 710 and the second sub-fixed plate 720 can be achieved by the adjusting component 400.

[0651] Thus, through the locking engagement between the locking member 410 and the second sub-fixing plate 720, and through the transmission engagement between the driving member 420 and the locking member 410, the duct fixing plate 100A can be adapted to windows of different sizes.

[0652] In some embodiments, as shown in Figures 97, 99, and 102, the adjusting assembly 400 further includes a cover plate 430. The cover plate 430 is disposed on the side of the drive member 420 opposite to the locking member 410. For example, the cover plate 430 covers the outside of the drive member 420, and the cover plate 430 locks into the drive member 420 so that after the drive member 420 rotates by a certain angle, the drive member 420 is fixed by the cover plate 430, thereby fixing the first sub-fixing plate 710 and the second sub-fixing plate 720.

[0653] In some embodiments, as shown in Figures 101 and 102, a first adjusting tooth 431 is provided on the side of the cover plate 430 facing the cam portion 422, and a plurality of second adjusting teeth 423 are provided on the cam portion 422. The first adjusting tooth 431 can be limited and engaged with any one of the plurality of second adjusting teeth 423.

[0654] In this way, when the cam portion 422 rotates to any angle, the first adjusting tooth 431 can cooperate with any of the second adjusting teeth 423, so that the cover plate 430 can be locked and fixed with the cam portion 422 rotated to any angle, thus realizing stepless adjustment between the first sub-fixed plate 710 and the second sub-fixed plate 720.

[0655] For example, multiple second adjusting teeth 423 can be arranged in an arc shape, so that when the cam part 422 is rotated to any angle, the first adjusting tooth 431 can cooperate with any one of the second adjusting teeth 423.

[0656] In some embodiments, as shown in Figures 97 and 102, a first hole 432 is provided on the cover plate 430, and a first arm 433 is provided within the first hole 432. A first adjusting tooth 431 is provided on the first arm 433, so that the first arm 433 can drive the first adjusting tooth 431 to move in a front-back direction (such as a second direction). For example, the second direction is perpendicular to the first direction.

[0657] For example, the first arm 433 can move relative to the cover plate 430 in the front-back direction (such as at least a portion of the first arm 433 can deform in the front-back direction), so that the first arm 433 can drive the first adjusting tooth 431 to move in the front-back direction, thereby allowing the first adjusting tooth 431 to be adjusted between two adjacent second adjusting teeth 423.

[0658] In addition, the first arm 433 can apply an elastic force to the cam portion 422, thereby enabling the first adjusting tooth 431 and the second adjusting tooth 423 to lock.

[0659] In some embodiments, as shown in Figures 97, 100 and 102, a second guide portion 434 (first mating post) is provided on the side of the cover plate 430 facing the cam portion 422. The second guide portion 434 passes through the cam portion 422 and is connected to the first sub-fixed plate 710.

[0660] For example, as shown in Figures 99 and 101, the drive member 420 also includes a third through hole 425. The third through hole 425 is disposed in and extends through the cam portion 422. The second guide portion 434 passes through the third through hole 425 and is fixedly connected to the first sub-fixed plate 710.

[0661] In some embodiments, as shown in FIG95, a seventh mating part 712 (first mating hole) is provided on the first sub-fixed plate 710. The second guide part 434 can pass through the third through hole 425 in the cam part 422 and be fixedly connected to the seventh mating part 712 on the first sub-fixed plate 710, thereby realizing the fixation between the cover plate 430 and the first sub-fixed plate 710.

[0662] In some embodiments, as shown in FIG99, the locking member 410 is provided with a first guide portion 4120 (first mating groove), and a second guide portion 434 is disposed within the first guide portion 4120. Thus, when the locking member 410 moves in the left-right direction, the second guide portion 434 slides within the first guide portion 4120, thereby guiding the locking member 410.

[0663] In some embodiments, as shown in Figures 97, 100, and 102, a fourth guide portion 435 (second mating post) is provided on the side of the cover plate 430 facing the cam portion 422. The fourth guide portion 435 is fixedly connected to the first mounting plate 710. A third guide portion 4130 (second mating groove) is provided on the locking member 410, and the fourth guide portion 435 is disposed within the third guide portion 4130. Thus, when the locking member 410 moves in the left-right direction, the fourth guide portion 435 slides within the third guide portion 4130, thereby guiding the locking member 410.

[0664] In some embodiments, as shown in FIG95, an eighth mating portion 713 (second mating hole) is provided on the first mounting plate 710, and a fourth guide portion 435 is mated within the eighth mating portion 713.

[0665] In some embodiments, as shown in FIG100, a second arm 4140 is provided on the side of the locking member 410 facing the cam portion 422. For example, the second arm 4140 extends in a vertical direction (such as a third direction). For example, the third direction is perpendicular to the first direction and perpendicular to the second direction.

[0666] The cam portion 422 and the second arm 4140 selectively abut. For example, when the cam portion 422 rotates to a first angle, the radius of the cam portion 422 in the left-right direction is small, and the cam portion 422 does not contact the second arm 4140. When the cam portion 422 rotates to a second angle, the radius of the cam portion 422 in the left-right direction is large, and the cam portion 422 abuts against the second arm 4140. In this case, the cam portion 422 can apply a force to the second arm 4140, and the second arm 4140 can apply an elastic force to the locking member 410, thereby causing the locking member 410 and the cover plate 430 to move away from each other in the left-right direction, and allowing the relative position between the first sub-fixed plate 710 and the second sub-fixed plate 720 to be finely adjusted, thereby adjusting the size of the duct fixing plate 100A in the left-right direction.

[0667] In some embodiments, as shown in Figures 97-100, a third arm 4160 is provided on the side of the locking member 410 opposite to the cam portion 422. A second locking portion 4110 is provided on the third arm 4160 (e.g., on the side of the third arm 4160 opposite to the cam portion 422), and a second unlocking portion 4170 is also provided on the third arm 4160. The third arm 4160 can apply an elastic force to the second locking portion 4110, so that the second locking portion 4110 can be stably locked with the first locking portion 722.

[0668] For example, the second locking part 4110 is located on the lower side of the third arm 4160, and the second unlocking part 4170 is located on one side of the third arm 4160 in the front-back direction.

[0669] For example, in the vertical direction, the second unlocking part 4170 is higher than the second sub-fixed plate 720 (e.g., higher than the plurality of first locking parts 722). Thus, when the second unlocking part 4170 is pushed (e.g., pushed upward), the third arm 4160 will deform, thereby causing the second locking part 4110 to move upward, thereby separating the second locking part 4110 from the first locking part 722.

[0670] In some embodiments, as shown in Figures 98, 100 and 101, the locking member 410 includes a first latching portion 4150, and a second latching portion 424 is provided at the connection between the driving portion 421 and the cam portion 422, wherein the first latching portion 4150 and the second latching portion 424 engage with each other.

[0671] For example, the first latching part 4150 and the second latching part 424 selectively engage. In this way, when the driving member 420 is in the initial position, the driving member 420 can be locked with the locking member 410, thereby preventing the driving member 420 from moving axially.

[0672] In some embodiments, as shown in Figures 95 and 96, a fifth guide portion 711 (first guide groove) is provided on both sides of the first sub-fixing plate 710 along the vertical direction, and a sixth guide portion 721 (second guide groove) corresponding to the fifth guide portion 711 is provided on both sides of the second sub-fixing plate 720. The fifth guide portion 711 and the sixth guide portion 721 are guided and engaged. In this way, the first sub-fixing plate 710 and the second sub-fixing plate 720 can achieve guided engagement through the fifth guide portion 711 and the sixth guide portion 721.

[0673] It is understandable that, through the mutual cooperation between the fifth guide portion 711 and the sixth guide portion 721, on the one hand, the limiting cooperation between the first sub-fixed plate 710 and the second sub-fixed plate 720 in the vertical direction can be realized, and on the other hand, the relative movement between the first sub-fixed plate 710 and the second sub-fixed plate 720 can be facilitated.

[0674] Some embodiments of this disclosure also provide a portable air conditioner assembly. The portable air conditioner assembly includes a portable air conditioner and a duct fixing plate 100A, with the duct assembly of the portable air conditioner and the duct fixing plate 100A fixedly connected.

[0675] In some embodiments, the portable air conditioner includes a refrigerant circuit. In the refrigerant circuit, the refrigerant circulates sequentially through a compressor, a condenser, a pressure reducer, and an evaporator, wherein one of the condenser and the evaporator is an outdoor heat exchanger and the other is an indoor heat exchanger.

[0676] In some embodiments, the portable air conditioner further includes a housing and an outdoor unit. The outdoor unit is located at the lower part of the housing and includes an outdoor air duct, an outdoor fan, a compressor, and an outdoor heat exchanger disposed within the housing.

[0677] The casing is equipped with an outdoor air inlet and an outdoor air outlet. Outdoor air enters the casing through the outdoor air inlet and then exits to the outside through the outdoor air outlet. The compressor, outdoor heat exchanger, and outdoor fan are housed inside the casing. Outdoor air enters the casing through the outdoor air inlet, undergoes heat exchange within the casing, and is then exhausted to the outside through the outdoor air outlet.

[0678] The compressor has an exhaust port and a return port. The compressor compresses the refrigerant, turning the low-pressure refrigerant into a high-pressure gaseous refrigerant. The low-pressure refrigerant enters the compressor through the return port. After the compressor compresses the low-pressure refrigerant into high-pressure refrigerant, the high-pressure refrigerant is discharged from the exhaust port. The refrigerant releases heat at the condenser, absorbs heat at the evaporator after pressure reduction, and finally enters the compressor through the return port.

[0679] The outdoor heat exchanger exchanges heat between outdoor air and the refrigerant transported within it. Outdoor air enters the unit casing through the outdoor air inlet and flows to the outdoor heat exchanger to exchange heat with the refrigerant. The refrigerant then circulates within the outdoor heat exchanger, and the outdoor air exchanges heat with it as it passes through. The heat-exchanged outdoor air then flows to the outdoor exhaust vent and is discharged outdoors.

[0680] For example, in the cooling mode of the portable air conditioner, the outdoor heat exchanger functions as a condenser, allowing the refrigerant compressed by the compressor to dissipate heat to the outdoor air and condense. In the heating mode of the portable air conditioner, the outdoor heat exchanger functions as an evaporator, allowing the depressurized refrigerant to absorb heat from the outdoor air and evaporate.

[0681] The outdoor fan rotates, driving outdoor air to enter the casing from the outdoor air inlet and flow to the outdoor heat exchanger. After the outdoor air exchanges heat with the refrigerant at the outdoor heat exchanger, the refrigerant is discharged to the outside from the outdoor exhaust vent under the drive of the outdoor fan.

[0682] In some embodiments, the portable air conditioner also includes an indoor unit. The indoor unit is located at the upper part of the casing and includes an indoor air duct, an indoor fan, and an indoor heat exchanger disposed within the casing.

[0683] The upper side of the casing is equipped with an indoor air inlet and an indoor air outlet. Indoor air enters the casing through the indoor air inlet and then enters the room through the indoor air outlet. The indoor heat exchanger, indoor fan, and indoor air duct components are located inside the casing. Indoor air enters the casing, undergoes heat exchange at the indoor heat exchanger, and then enters the room through the indoor air outlet.

[0684] The indoor heat exchanger exchanges heat between indoor air and the refrigerant transported within it. Indoor air enters the unit casing through the indoor air inlet and flows to the indoor heat exchanger to exchange heat with the refrigerant. The refrigerant then circulates within the heat exchanger, and the indoor air exchanges heat with it as it passes through. The heat-exchanged indoor air then flows to the indoor air outlet and is exhausted into the room.

[0685] For example, in the cooling mode of the portable air conditioner, the indoor heat exchanger functions as an evaporator, allowing the depressurized refrigerant to absorb heat from the indoor air and evaporate. In the heating mode of the portable air conditioner, the indoor heat exchanger functions as a condenser, allowing the refrigerant compressed by the compressor to dissipate heat to the indoor air and condense.

[0686] The indoor fan rotates, driving airflow from the indoor air inlet into the casing to exchange heat with the indoor heat exchanger, and then flowing out of the indoor air outlet into the room. Driven by the indoor fan, indoor air enters the casing from the indoor air inlet and flows to the indoor heat exchanger. After exchanging heat with the refrigerant at the indoor heat exchanger, the refrigerant is discharged into the room from the indoor air outlet under the drive of the indoor fan.

[0687] In some embodiments, the portable air conditioner further includes a duct assembly, a first end of which is connected to at least one of an outdoor exhaust vent or an outdoor air inlet, and a second end of which is fixedly connected to a duct mounting plate 100A. Thus, air circulation between the outdoor unit and the outside environment can be achieved through the duct assembly.

[0688] In some embodiments, the duct assembly includes an air inlet duct, an air outlet duct, and a mounting plate. A first end of the air inlet duct is connected to an outdoor air inlet of the outdoor duct component, and a first end of the air outlet duct is connected to an outdoor air exhaust outlet of the outdoor duct component. The air inlet duct is used to draw in fresh air from the outside, and the air outlet duct is used to exhaust heat generated by the outdoor unit to the outside, preventing the indoor air from overheating.

[0689] In this way, when the portable air conditioner is not in use, the air inlet pipe, air outlet pipe, and mounting plate can be stored together at the rear of the casing, thus saving indoor space.

[0690] Understandably, scenarios requiring the use of portable air conditioners typically involve limited space and numerous items. The above setup prevents the air inlet and outlet ducts from taking up excessive indoor space. Storing the air inlet and outlet ducts also effectively prevents them from being accidentally stepped on or bumped, reducing the risk of damage and extending the lifespan of the portable air conditioner.

[0691] When using the portable air conditioner, the mounting plate, the second end of the air inlet pipe, and the second end of the air outlet pipe can be removed from the back of the casing and fixed to the duct fixing plate 100A. The mounting plate and the casing are fixed by snap-fit, which helps to improve the stability and firmness of the duct fixing plate 100A and the duct assembly, and the mounting plate is not easy to loosen or fall off.

[0692] Furthermore, compared to bolted or clamped connections, snap-fit ​​connections are easier to install and remove, and the operation of taking out and putting in the mounting plate is simple and quick, saving users time and improving the convenience of using portable air conditioners.

[0693] The duct assembly includes multiple third snap-fit ​​parts. These third snap-fit ​​parts are located around the periphery of the mounting plate. These third snap-fit ​​parts are used to engage with the duct fixing plate 100A of the window.

[0694] In this way, when the portable air conditioner is in operation, the mounting plate can be removed from the casing and fixed to the window duct mounting plate 100A using multiple third snap-fit ​​parts, which facilitates the outdoor unit to draw in air from the outside and expel heat.

[0695] In some embodiments, the plurality of third latching portions include six third latching portions, which are distributed at intervals along the periphery of the mounting plate and are symmetrically arranged in the left-right and front-back directions of the mounting plate, so that the mounting plate is subjected to uniform force and avoids problems such as latching or deformation of the mounting plate caused by uneven force.
