[0121] The following will clearly and completely describe some embodiments of the present disclosure in conjunction with the accompanying drawings. However, the described embodiments are only some embodiments of the present disclosure, not all embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present disclosure.

[0122] Unless the context requires otherwise, throughout the specification and claims, the term "comprise" and its other forms, such as the third person singular form "comprises" and the present participle form "comprising", are to be interpreted as open and inclusive, that is, "including, but not limited to". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "example", "specific example" or "some examples" are intended to indicate that the particular features, structures, materials or characteristics associated with the embodiment or example are included in at least one embodiment or example of the present disclosure. The schematic representation of the above terms does not necessarily refer to the same embodiment or example. In addition, the particular features, structures, materials or characteristics may be included in any one or more embodiments or examples in any appropriate manner.

[0123] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present disclosure, unless otherwise specified, "plurality" means two or more.

[0124] When describing some embodiments, the expressions "coupled" and "connected" and their derivatives may be used. The term "connected" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. The term "coupled" indicates that two or more components are in direct physical or electrical contact. The term "coupled" or "communicatively coupled" may also refer to two or more components that are not in direct contact with each other, but still cooperate or interact with each other. The embodiments disclosed herein are not necessarily limited to the contents of this document.

[0125] “At least one of A, B and C” has the same meaning as “at least one of A, B or C” and both include the following combinations of A, B and C: A only, B only, C only, the combination of A and B, the combination of A and C, the combination of B and C, and the combination of A, B and C.

[0126] The use of "adapted to" or "configured to" herein is intended to be open and inclusive language that does not exclude devices adapted or configured to perform additional tasks or steps.

[0127] As used herein, "about," "substantially," or "approximately" includes the stated value and an average value that is within an acceptable range of deviation from the particular value as determined by one of ordinary skill in the art taking into account the measurements in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system).

[0128] Typically, an air deflector is installed at the air outlet of an air conditioner's indoor unit. The deflector extends along the length of the indoor unit, with a gap between each end of the deflector and the indoor unit's housing. For example, a portion of the housing defines the air outlet, and a gap is formed between each end of the deflector and the ends of the housing. These gaps are approximately equal to ensure reliable rotation of the deflector.

[0129] However, during the rotation of the air deflector, the air deflector is prone to shaking, causing the air deflector to deviate along the length direction of the indoor unit, resulting in different sizes of the two gaps. This not only affects the aesthetics of the indoor unit, but also affects the operation of the air deflector.

[0130] In some schemes, a limiting structure is usually provided to limit the connection position between the air guide plate and the shell to prevent the air guide plate from being offset along the length direction of the shell. However, the positioning accuracy of the air guide plate by the limiting structure is poor, and since the length of the indoor unit is long, the length of the air guide plate is also long, which will cause the air guide plate to easily shake relative to the shell when rotating, which not only affects the stability of the air outlet of the indoor unit, but also increases the offset of the air guide plate along the length direction of the shell.

[0131] To address the above-mentioned issues, some embodiments of the present disclosure provide an air conditioner 1000. Air conditioner 1000 includes an indoor unit comprising a support member and a first constraint portion. When the air deflector rotates to a target position, the support member adjusts the connection position of the air deflector with the support member along the length of the housing via the first constraint portion; the target position refers to the position of the air deflector when the first constraint portion and the support member contact each other. This prevents the air deflector from shifting along the length of the housing, thereby increasing the stability of the airflow from the indoor unit.

[0132] In some embodiments, as shown in FIG. 1A and FIG. 1B , the air conditioner 1000 includes an outdoor unit 20 .

[0133] 1B , the outdoor unit 20 includes a compressor 2019. The compressor 2019 is configured to compress the refrigerant so that the low-pressure refrigerant is compressed to form a high-pressure refrigerant.

[0134] As shown in FIG1B , the outdoor unit 20 also includes an outdoor heat exchanger 2020. The outdoor heat exchanger 2020 is configured to exchange heat between outdoor air and the refrigerant transmitted through the outdoor heat exchanger 2020. For example, in the cooling mode of the air conditioner 1000, the outdoor heat exchanger 2020 operates as a condenser, causing the refrigerant compressed by the compressor 2019 to condense by dissipating heat to the outdoor air through the outdoor heat exchanger 2020. In the heating mode of the air conditioner 1000, the outdoor heat exchanger 2020 operates as an evaporator, causing the decompressed refrigerant to absorb heat from the outdoor air through the outdoor heat exchanger 2020 and evaporate. The outdoor heat exchanger 2020 is equipped with a coil connected to the refrigerant circuit. The refrigerant flows through the coil of the outdoor heat exchanger 2020 to exchange heat with the outdoor air.

[0135] As shown in Figure 1B, the outdoor unit 20 also includes an expansion valve 204. The expansion valve 204 is connected between the outdoor heat exchanger 2020 and the indoor heat exchanger 300. The opening of the expansion valve 204 regulates the pressure of the refrigerant flowing through the outdoor heat exchanger 2020 and the indoor unit 10, thereby adjusting the refrigerant flow between the outdoor heat exchanger 2020 and the indoor heat exchanger 300. The flow rate and pressure of the refrigerant flowing between the outdoor heat exchanger 2020 and the indoor heat exchanger 300 affect the heat exchange performance of the outdoor heat exchanger 2020 and the indoor unit 10. The opening of the expansion valve 204 is adjustable to control the flow rate and pressure of the refrigerant flowing through the expansion valve 204. For example, the expansion valve 204 expands the liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant.

[0136] 1B , the outdoor unit 20 further includes a four-way valve 2050. The four-way valve 2050 is connected to the refrigerant circuit and is configured to switch the flow direction of the refrigerant in the refrigerant circuit so that the air conditioner 1000 can operate in cooling mode or heating mode.

[0137] As shown in FIG1B , the outdoor unit 20 further includes an outdoor fan 203. The outdoor fan 203 is configured to draw outdoor air into the outdoor unit 20 through the outdoor air inlet of the outdoor unit 20 and to deliver the outdoor air, after heat exchange with the outdoor heat exchanger 2020, through the outdoor air outlet of the outdoor unit 20. The outdoor fan 203 provides power to move the outdoor air, causing the outdoor air to flow through the outdoor heat exchanger 2020 and exchange heat with the refrigerant in the outdoor heat exchanger 2020.

[0138] In some embodiments, the outdoor unit 20 includes a second housing defining a second installation cavity.

[0139] In some embodiments, the outdoor unit 20 further includes a second air inlet. The second air inlet is provided in the second housing and communicates with the second installation cavity. The second air inlet is configured to introduce outdoor air into the second installation cavity.

[0140] In some embodiments, the outdoor unit 20 further includes a second air outlet. The second air outlet is provided in the second housing and communicates with the second installation cavity. The second air outlet is configured to guide air in the second installation cavity out of the second installation cavity.

[0141] 1A and 1B , the air conditioner 1000 further includes an indoor unit 10. The indoor unit 10 and the outdoor unit 20 are connected by a pipeline to transmit refrigerant.

[0142] It should be noted that FIG1A illustrates an example in which the air conditioner 1000 is a wall-mounted air conditioner, with the indoor unit 10 mounted on a wall. Of course, the air conditioner 1000 in some embodiments of the present disclosure may also be a floor-standing air conditioner. Furthermore, because the indoor unit 10 in FIG1A is located indoors, while the outdoor unit 20 is located outdoors, the outdoor unit 20 is represented by a dotted line in FIG1A .

[0143] In some embodiments, as shown in FIG1C and FIG2 , the indoor unit 10 includes a housing 100 (casing). The housing 100 has a top and a bottom at its two ends in the height direction. The housing 100 has a left side and a right side at its two ends in the length direction. The housing 100 has a front side and a rear side at its two ends in the width direction.

[0144] In some embodiments, the housing 100 is disposed on the top of the room or in an upper space of the room, with the rear side of the housing 100 facing the wall and the front side of the housing 100 facing the user.

[0145] In some embodiments, as shown in Figure 2, the indoor unit 10 further includes a heat exchanger 300. A heat exchange channel is formed inside the housing 100, and the heat exchanger 300 is disposed in the heat exchange channel to exchange heat with air entering the heat exchange channel.

[0146] In some embodiments, the indoor unit 10 further includes a heat exchange fan, which is disposed in the heat exchange channel to exchange heat with the air entering the heat exchange channel.

[0147] As shown in Figures 1C and 2, the housing 100 includes a first air inlet 101, which is connected to the heat exchange channel. Indoor air enters the heat exchange channel through the first air inlet 101. The first air inlet 101 is located at the top of the housing 100 and extends along the length of the housing 100.

[0148] As shown in Figure 8, the housing 100 also includes a first air outlet 102. The first air outlet 102 is connected to the heat exchange channel, and the air in the heat exchange channel is discharged into the room through the first air outlet 102. The first air outlet 102 extends along the length of the housing 100. The first air outlet 102 is located on the front side of the housing 100 and is located near the bottom of the housing 100. That is, the first air outlet 102 is located on the lower front side of the housing 100.

[0149] It should be noted that the indoor air passes through the first air inlet 101 through the heat exchange channel and is output to the indoor through the first air outlet 102 .

[0150] 6 , the housing 100 further includes a first sub-housing 110 (outer cover). The first sub-housing 110 defines a fourth cavity with an opening toward the rear of the housing 100. The heat exchanger 300 and the heat exchange fan are located in the fourth cavity.

[0151] In some embodiments, the first sub-housing 110 is in a frame structure, which not only facilitates the contact between the heat exchanger 300 and the air inside the housing 100 , but also reduces the weight of the first sub-housing 110 .

[0152] In some embodiments, as shown in FIG. 6 , the first air inlet 101 is disposed on the top of the first sub-housing 110 .

[0153] In some embodiments, the housing 100 further includes a grille disposed at the first air inlet 101 to prevent dust or debris from entering the interior of the housing 100 through the first air inlet 101 .

[0154] In some embodiments, the grille and the first sub-housing 110 are integrally formed, and the integral part can be formed by injection molding, thereby reducing the number of parts and lowering costs.

[0155] In some embodiments, the grille is provided with a process-proof groove to prevent shrinkage of the first sub-housing 110 during injection molding. However, the process-proof groove can affect the structural strength of the air inlet grille. For example, if the process-proof groove is provided in an area of ​​the first sub-housing 110 that is subjected to greater stress, it may cause cracking in the first sub-housing 110.

[0156] In some embodiments, as shown in FIG6 , the housing 100 further includes a second sub-housing 140 (base). The second sub-housing 140 is disposed at the opening of the fourth cavity. The second sub-housing 140 and the first sub-housing 110 define a heat exchange channel. The heat exchanger 300 and the heat exchange fan are mounted in the second sub-housing 140 .

[0157] 15 and 16 , the housing 100 further includes a first opening 114 . The first opening 114 is provided at the bottom of the front side of the first sub-housing 110 .

[0158] 57 , the housing 100 further includes a second opening 149 . The second opening 149 is provided at the bottom of the front side of the second sub-housing 140 . The second opening 149 corresponds to the first opening 114 to define the first air outlet 102 .

[0159] 2 and 3 , the indoor unit 10 further includes a first reinforcing rib 112 . The first reinforcing rib 112 is provided on the first sub-housing 110 and at the first air inlet 101 to increase the strength of the first sub-housing 110 .

[0160] The first reinforcing rib 112 extends along the front-to-back direction of the housing 100 , so that the first reinforcing rib 112 is connected to both ends of the first air inlet 101 extending along the length direction of the housing 100 .

[0161] It should be noted that the first reinforcing rib 112 may be provided in a region where the first sub-housing 110 and the second sub-housing 140 are subjected to greater force when mating.

[0162] In some embodiments, as shown in FIG24 , the housing 100 further includes a second air inlet 121. The second air inlet 121 is in communication with the heat exchange channel, and indoor air can enter the heat exchange channel through the second air inlet 121.

[0163] It should be noted that, by providing the second air inlet 121 on the housing 100 , the air intake volume of the indoor unit 10 can be increased, thereby increasing the air discharge volume of the indoor unit 10 .

[0164] In some embodiments, the opening direction of the second air inlet 121 is arranged along the length direction of the housing 100 .

[0165] In some embodiments, as shown in Figures 15, 19, 20, and 24, the housing 100 further includes at least one side cover 120. The side cover 120 is disposed at one end of the first sub-housing 110 along the length of the housing 100, and the second air inlet 121 is provided in the side cover 120.

[0204] In some embodiments, as shown in FIG27 , the indoor unit 10 further includes a third support portion 126. The third support portion 126 is provided on a side of the side cover 120 facing the third chamber 103. The third support portion 126 contacts the side wall of the first sub-housing 110 facing the third chamber 103 to support the side cover 120 and the first sub-housing 110, thereby increasing the connection strength between the side cover 120 and the first sub-housing 110.

[0205] In some embodiments, the third support portion 126 is located above the second support portion 122 .

[0206] It should be noted that through the operation of the heat exchange fan, a part of the indoor air enters the heat exchange channel from the first air inlet 101 and contacts the heat exchanger 300, and the other part of the indoor air enters the heat exchange channel from the second air inlet 121 through the third cavity 103 and contacts the heat exchanger 300. The heat exchanger 300 heats the indoor air in the heat exchange channel to form air-conditioned air, which is output to the room through the first air outlet 102.

[0207] In some embodiments, as shown in FIG10 , the housing 100 further includes a third side panel 150 (panel). The third side panel 150 is located on a side of the first air outlet 102 that is closer to the first air inlet 101 (e.g., above the first air outlet 102). The third side panel 150 is disposed on the front side of the first sub-housing 110 and is detachably connected to the first sub-housing 110. This allows the interior of the housing 100 to be inspected by removing the third side panel 150 in the event of a malfunction of the indoor unit 10.

[0208] It should be noted that since the third side panel 150 is detachably connected to the first sub-shell 110, there will be a certain gap between the third side panel 150 and the front side of the first sub-shell 110, and the third side panel 150 is located above the first air outlet 102. Therefore, when the air-conditioned air is output from the first air outlet 102 to the room, it is easy to flow into the gap, causing condensation on the side of the third side panel 150 facing the first sub-shell 110, affecting the operation of components such as the heat exchanger 300.

[0209] In some embodiments, as shown in FIG11 , the housing 100 further includes a receiving portion 113 . The receiving portion 113 is disposed on a side (e.g., a front side) of the first sub-housing 110 near the third side panel 150 . The receiving portion 113 is located above the first air outlet 102 and extends along the length of the housing 100 .

[0210] In some embodiments, as shown in FIG11 , the housing 100 further includes a first rib 151 (convex rib). The first rib 151 is disposed on the third side plate 150 , close to the side of the third side plate 150 toward the bottom of the housing 100 , and extends along the length of the housing 100 .

[0211] It should be noted that the first rib 151 is provided corresponding to the accommodating portion 113. The first rib 151 is provided in the accommodating portion 113 to cover the gap between the third side panel 150 and the front side of the first sub-housing 110, preventing air conditioning air from entering the gap, thereby preventing condensation from forming on the side of the third side panel 150 facing the first sub-housing 110.

[0212] In some embodiments, the first rib 151 is located at an outer edge of the third side plate 150 facing the bottom of the housing 100 .

[0213] In some embodiments, the first sub-housing 110 is connected to the second sub-housing 140 by fasteners such as bolts or screws.

[0214] 31 , the housing 100 further includes a first hole 106 . The first connection hole 106 is provided in the first sub-housing 110 .

[0215] 58 , the housing 100 further includes a second hole 1414. The second connection hole 1414 is provided in the second sub-housing 140. A fastener is provided through the first connection hole 106 and the second connection hole 1414 to connect the first sub-housing 110 and the second sub-housing 140 to each other.

[0216] It should be noted that the fasteners can be shielded to avoid the fasteners being exposed on the surface of the first sub-housing 110 or the second sub-housing 140 to affect the aesthetics of the indoor unit 10, and to facilitate protection of the fasteners.

[0217] 30 and 31 , the housing 100 further includes a second connection portion 1115 . The second connection portion 1115 is provided on the first sub-housing 110 .

[0218] In some embodiments, as shown in Figures 30 and 31 , the housing 100 further includes a second cavity 104 (accommodating cavity). The second connecting portion 1115 defines the second cavity 104, and the second cavity 104 is provided with a third opening.

[0219] When the first sub-shell 110 and the second sub-shell 140 are connected to each other by fasteners, the end of the fastener away from the first connecting hole 106 is arranged in the second cavity 104. In this way, the fastener can be shielded to prevent the fastener from affecting the aesthetics of the indoor unit 10, and the fastener can be prevented from contacting dust, etc., to protect the fastener to avoid corrosion of the fastener and other factors affecting the connection effect between the first sub-shell 110 and the second sub-shell 140.

[0220] In some embodiments, the second cavity 104 opens generally toward the front of the housing 100. A first connecting hole 106 is provided in the cavity wall of the second cavity 104 on a side opposite the third opening, so that a fastener can pass from the third opening through the second cavity 104 and through the first connecting hole 106 to connect to the second sub-housing 140.

[0221] In this way, by opening the second cavity 104 in the second connecting portion 1115, one end of the fastener away from the first connecting hole 106 is arranged in the second cavity 104 to hide the fastener and prevent the fastener from protruding from the surface of the first sub-shell 110. On the one hand, this is to prevent the fastener from affecting the aesthetics of the air-conditioning indoor unit. On the other hand, the fastener can also be protected to prevent the fastener from affecting the connection effect between the first sub-shell 110 and the second sub-shell 140 due to corrosion, etc.

[0222] In some embodiments, as shown in FIG9 , the indoor unit 10 further includes a cover 700 (cover). The cover 700 is provided at the third opening to close the second cavity 104 to prevent the second cavity 104 from affecting the aesthetics of the indoor unit 10 and to protect and shield fasteners.

[0223] In some embodiments, as shown in FIG36 , the indoor unit 10 further includes a hanging portion 710 (hanging cover). The hanging portion 710 is provided on the cover 700 so that the housing 100 constrains the cover 700 through the hanging portion 710 to prevent the cover 700 from being lost.

[0224] In some embodiments, the covering portion 700 opens or closes the second cavity 104 in a rotatable manner, one end of the hanging portion 710 is connected to the covering portion 700 and faces one side of the second cavity 104, and the other end of the hanging portion 710 is rotatably connected to the second connecting portion 1115.

[0225] If the cover 700 rotates to a smaller angle when opening the second cavity 104, the cover 700 may interfere with the installation and removal of the fastener. Although the rotation angle of the cover 700 can be increased by increasing the length of the hanging portion 710, the larger hanging portion 710 may interfere with the second cavity 104 when the cover 700 closes the third opening, given the limited volume of the second cavity 104.

[0226] In some embodiments, as shown in Figures 32 to 35, the indoor unit 10 further includes a third opening 105 (first exit). The third opening 105 is provided in the wall of the second cavity 104 so that the end of the hanging portion 710 away from the covering portion 700 can pass through the second cavity 104 through the third opening 105. This prevents the wall of the second cavity 104 from interfering with the hanging portion 710, thereby increasing the rotation angle of the covering portion 700 and preventing the covering portion 700 from interfering with the installation and removal of the fasteners.

[0227] In some embodiments, as shown in FIG. 34 to FIG. 36 , one end of the hanging portion 710 away from the covering portion 700 is disposed outside the second cavity 104 through the third opening 105 .

[0228] When the covering portion 700 opens the second cavity 104 , the end of the hanging portion 710 away from the covering portion 700 moves toward the cavity wall of the second cavity 104 where the third opening 105 is provided.

[0229] When the covering portion 700 closes the second cavity 104 , the end of the hanging portion 710 away from the covering portion 700 moves toward the cavity wall away from the second cavity 104 where the third opening 105 is provided.

[0230] In this way, by providing the third opening portion 105 on the wall of the second cavity 104, the end of the hanging portion 710 away from the covering portion 700 passes through the third opening portion 105 and is located outside the second cavity 104, so that the indoor unit 10 can increase the rotation angle of the covering portion 700 when opening the second cavity 104 by increasing the length of the hanging portion 710, thereby preventing the covering portion 700 from affecting the installation and disassembly of the fasteners.

[0231] In some embodiments, as shown in Figures 34 and 35, the indoor unit 10 further includes a second blocking portion 713. The second blocking portion 713 is provided at one end of the hanging portion 710 located outside the second cavity 104. The second blocking portion 713 is located outside the second cavity 104 and cooperates with the outer edge of the third opening 105 to prevent the end of the hanging portion 710 located outside the second cavity 104 from passing through the third opening 105 back into the second cavity 104, thereby preventing the hanging portion 710 from separating from the second connecting portion 1115.

[0232] When the second cavity 104 is opened by the covering portion 700, the end of the hanging portion 710 away from the covering portion 700 moves toward the second cavity 104. When the second blocking portion 713 contacts the outer edge of the third opening portion 105, the hanging portion 710 moves to the extreme position and cannot continue to move toward the second cavity 104. At this time, the covering portion 700 is at the maximum rotation angle when the second cavity 104 is opened.

[0233] In some embodiments, as shown in FIG36 , the indoor unit 10 further includes a fifth position-limiting portion 712 . The fifth position-limiting portion 712 is disposed on the hanging portion 710 , and is disposed close to the covering portion 700 .

[0234] When the second cavity 104 is closed by the covering portion 700 , the fifth limiting portion 712 is located outside the second cavity 104 by the third opening portion 105 and contacts the outer edge of the third opening portion 105 to prevent the hanging portion 710 from moving, thereby allowing the covering portion 700 to close the second cavity 104 .

[0235] Thus, by providing the fifth limiting portion 712 on the hanging portion 710 , the fifth limiting portion 712 abuts against the outer edge of the third opening 105 so that the covering portion 700 closes the second cavity 104 , thereby increasing the reliability of the covering portion 700 in closing the second cavity 104 .

[0236] In some embodiments, as shown in FIG37 , the indoor unit 10 further includes a second stopper 711. The second stopper 711 is disposed on the hanging portion 710. The second stopper 711 is disposed near an end of the hanging portion 710 away from the covering portion 700, and the second stopper 711 cooperates with an outer edge of the third opening.

[0237] When the second blocking portion 713 contacts the outer edge of the third opening 105 , the second limiting portion 711 is located outside the second cavity 104 and contacts the outer edge of the third opening to prevent the hanging portion 710 from moving, thereby allowing the covering portion 700 to open the second cavity 104 .

[0238] It should be noted that, under the action of external force, the second limiting portion 711 is deformed from inside the second cavity 104 to outside the second cavity 104 through at least one of the second limiting portion 711 and the outer edge of the third opening.

[0239] In some embodiments, when the second cavity 104 is closed by the covering portion 700, the second limiting portion 711 needs to be arranged in the second cavity 104 by the third opening, and then arranged outside the second cavity 104 by the third opening portion 105, and the fifth limiting portion 712 also needs to be arranged in the second cavity 104 by the third opening, and then arranged outside the second cavity 104 by the third opening portion 105.

[0240] In this way, by providing the second limiting portion 711 and utilizing the second limiting portion 711 to abut against the outer edge of the third opening, the cover portion 700 can open the second cavity 104, thereby increasing the reliability of the cover portion 700 in opening the second cavity 104 and facilitating the installation or removal of fasteners.

[0241] It should be noted that the fifth limiting portion 712 makes a sound and generates vibration when passing through the third opening 105, and the fifth limiting portion 712 also makes a sound and generates vibration when passing through the third opening. The second limiting portion 711 makes a sound and generates vibration when passing through the third opening, and the second limiting portion 711 also makes a sound and generates vibration when passing through the third opening 105.

[0242] In some embodiments, when the fifth limiting portion 712 is located outside the second cavity 104 through the third opening 105 , it is determined that the covering portion 700 is closed.

[0243] In some embodiments, when the second limiting portion 711 contacts the outer edge of the third opening, it is determined that the covering portion 700 is opened.

[0244] It should be noted that during the installation of the indoor unit 10, due to the small size of the cover 700, it is difficult to determine whether the cover 700 is closed or open. Therefore, the cover 700 can be closed or opened based on at least one of sound and vibration.

[0245] It should be noted that when the cover part 700 closes the second cavity 104, the second limiting part 711 needs to be set in the second cavity 104 by the third opening, and then be set outside the second cavity 104 by the third opening part 105. The fifth limiting part 712 also needs to be set in the second cavity 104 by the third opening, and then be set outside the second cavity 104 by the third opening part 105. Therefore, when the cover part 700 closes the second cavity 104, it usually emits four sounds and produces four vibrations; when the cover part 700 opens the second cavity 104, it also usually emits four sounds and produces four vibrations.

[0246] In some embodiments, two hanging portions 710 are provided, and the two hanging portions 710 are provided correspondingly, and the second blocking portion 713, the fifth limiting portion 712, and the second limiting portion 711 are respectively provided on the sides of the two hanging portions 710 facing away from each other. In this way, the restraining force between the second connecting portion 1115 and the covering portion 700 can be increased.

[0247] In some embodiments, the indoor unit 10 further includes two third openings 105. The two third openings 105 are respectively provided corresponding to the two hanging portions 710.

[0248] In some embodiments, the third opening 105 is an opening opened in the wall of the second cavity 104 .

[0263] In some embodiments, as shown in Figures 2, 4, and 51 to 53, the indoor unit 10 also includes a first air guide plate 200 (air guide plate), which is connected to the shell 100 and opens or closes the first air outlet 102 in an openable and closable manner.

[0264] It should be noted that the airflow from the first air outlet 102 into the room is likely to directly hit the human body. Therefore, by adjusting the rotation angle of the first air guide plate 200, the direction of the conditioned air output from the first air outlet 102 into the room can be adjusted. In this way, the airflow from the first air outlet 102 into the room can be prevented from directly hitting the human body.

[0265] The first air guide plate 200 rotates around its rotation axis to open or close the first air outlet 102. The rotation axis of the first air guide plate 200 is arranged along the length direction of the first air outlet 102.

[0266] It should be noted that the side of the first air guide plate 200 close to the rotation axis of the first air guide plate 200 is the root of the first air guide plate 200 .

[0267] In some embodiments, as shown in Fig. 52, the indoor unit 10 further includes at least one first motor 240. The first motor 240 is connected to the first air guide plate 200 and is configured to drive the first air guide plate 200 to rotate.

[0268] The first motor 240 is connected to one end of the first air guide plate 200 along the length direction of the housing 100 . The first motor 240 is disposed on a side of the first air guide plate 200 close to the rotation axis of the first air guide plate 200 .

[0269] It should be noted that the rotation axis of the first motor 240 and the rotation axis of the first air guide plate 200 are arranged colinearly.

[0275] In some embodiments, the at least one connecting ear portion includes two connecting ears to increase the secureness of the installation of the first motor 240. Accordingly, the at least one first fixing portion 1422 includes two first fixing portions 1422, and the two first fixing portions 1422 are respectively disposed corresponding to the two connecting ears.

[0276] In some embodiments, as shown in FIG102 , the indoor unit 10 further includes a ninth mating portion 1421 (second protruding portion). The ninth mating portion 1421 is disposed on the second sub-housing 140 and is located on both sides of the second opening 149 along the length of the housing 100 , so that the first motor 240 can pass through the ninth mating portion 1421 and rotatably connect to the first air guide plate 200 disposed at the second opening 149 .

[0277] In some embodiments, the ninth mating portion 1421 is an opening provided at an edge of the second sub-housing 140 correspondingly provided along the length direction of the housing 100 .

[0278] In some embodiments, as shown in FIG102 , the indoor unit 10 further includes a fourth support portion 1423 . The fourth support portion 1423 is provided on the second sub-housing 140 and configured to support the first motor 240 to prevent the first motor 240 from tilting and affecting the rotation of the first air guide plate 200 .

[0279] The fourth supporting portion 1423 is disposed at one end of the second sub-housing 140 along the length direction of the housing 100 and is located on a side of the second sub-housing 140 away from the heat exchange channel.

[0280] In some embodiments, the fourth supporting portion 1423 is disposed near an edge of the second opening 149 .

[0281] Since the first motor 240 may tilt at any angle, in some embodiments, the fourth support portion 1423 is centered on the first motor 240 and extends as far as possible along the contour of the motor body 511 of the first motor 240 to enhance the support effect on the motor body 511 and reduce any angle of skewness.

[0282] When the conditioned air is output to the room from the first air outlet 102 , it will contact the windward side of the first air guide plate 200 . The heat or cold in the conditioned air will be transferred to the first air guide plate 200 , which may easily cause the first air guide plate 200 to deform due to heat or cold.

[0283] In some embodiments, as shown in FIG70 , the first wind deflector 200 includes a first sub-wind deflector 210 . The first sub-wind deflector 210 is located on the leeward side of the first wind deflector 200 .

[0284] In some embodiments, as shown in FIG70 , the first air deflector 200 further includes a second sub-air deflector 220 . The second sub-air deflector 220 is located on the windward side of the first air deflector 200 .

[0286] In some embodiments, the side of the second sub-air deflector 220 away from the first sub-air deflector 210 is the windward side of the second sub-air deflector 220. The shape of the windward side of the second sub-air deflector 220 is adapted to the flow path of the conditioned air output from the first air outlet 102 into the room. For example, the second sub-air deflector 220 is streamlined to better guide the flow of the conditioned air.

[0287] In some embodiments, as shown in Figures 68 and 71 , the first air deflector 200 further includes at least one eleventh mating portion 211 (protrusion). The eleventh mating portion 211 is disposed on the first sub-air deflector 210. For example, the eleventh mating portion 211 is disposed on one side of the first sub-air deflector 210 extending along the length direction of the housing 100.

[0288] In some embodiments, as shown in FIG69 , the first air deflector 200 further includes at least one second mating portion (extending portion) 221. The second mating portion (extending portion) 221 is provided on the second sub-air deflector 220, and the second mating portion 221 is provided on a middle side of the second sub-air deflector 220 extending along the length direction of the housing 100.

[0289] The eleventh matching portion 211 and the second matching portion 221 are correspondingly arranged to connect the first sub-air deflector 210 and the second sub-air deflector 220 to each other.

[0290] 70 , the first air deflector 200 further includes a first abutting portion 213 . The first abutting portion 213 is disposed on the first sub-air deflector 210 , for example, on one side of the first sub-air deflector 210 extending along the length direction of the housing 100 .

[0291] In some embodiments, as shown in FIG70 , the first air deflector 200 further includes a second abutting portion 223 . The second abutting portion 223 is provided on the second sub-air deflector 220 , and is provided on one side of the second sub-air deflector 220 extending along the length direction of the housing 100 .

[0292] The first abutting portion 213 and the second abutting portion 223 are correspondingly disposed to connect the first sub-air deflector 210 and the second sub-air deflector 220 to each other.

[0293] It should be noted that the eleventh matching portion 211 and the first abutting portion 213 are correspondingly provided on two sides of the first sub-air guide plate 210 extending along the length direction of the housing 100 .

[0294] The second matching portion 221 and the second abutting portion 223 are respectively provided on two sides of the second sub-air deflector 220 extending along the width direction of the air deflector 200 .

[0295] When the first sub-air deflector 210 and the second sub-air deflector 220 are connected to each other, the first abutting portion 213 and the second abutting portion 223 may be abutted against each other first, and then the eleventh matching portion 211 may be disposed on the second matching portion 221 .

[0296] In some embodiments, the portion where the first abutting portion 213 and the second abutting portion 223 abut against each other is an inclined plane.

[0297] In some embodiments, the eleventh matching portion 211 is located on a side of the first sub-air deflector 210 close to the rotation axis of the first air deflector 200 .

[0298] In some embodiments, the eleventh matching portion 211 is located on a side of the first sub-air deflector 210 facing the second sub-air deflector 220 .

[0299] In some embodiments, the first abutting portion 213 is located on a side of the first sub-air guide plate 210 away from the rotation axis of the first air guide plate 200 .

[0300] In some embodiments, the first abutting portion 213 is located on a side of the first sub-air deflector 210 facing the second sub-air deflector 220 .

[0301] In some embodiments, the second matching portion 221 is located on a side of the second sub-air deflector 220 close to the rotation axis of the first air deflector 200 .

[0302] In some embodiments, the second matching portion 221 is located on a side of the second sub-air deflector 220 facing the first sub-air deflector 210 .

[0303] In some embodiments, the second abutting portion 223 is located on a side of the second sub-air deflector 220 away from the rotation axis of the first air deflector 200 .

[0304] In some embodiments, the second abutting portion 223 is located on a side of the second sub-air deflector 220 facing the first sub-air deflector 210 .

[0305] In some embodiments, as shown in FIG71 , the first air deflector 200 further includes a first edge 222 (flange). The first edge 222 is located on a side of the second sub-air deflector 220 close to the air deflector rotation axis. The second mating portion 221 is located on the first edge 222 .

[0306] In some embodiments, as shown in FIG71 , the first air deflector 200 further includes at least one first abutment portion 212 (abutment portion). The first abutment portion 212 is disposed on the body of the first sub-air deflector 210. The first abutment portion 212 cooperates with the first edge 222 to locate the installation position of the second sub-air deflector 220 and the first sub-air deflector 210.

[0307] In some embodiments, the at least one first stopping portion 212 includes a plurality of first stopping portions 212 , and the plurality of first stopping portions 212 are distributed along the length direction of the housing 100 .

[0308] In some embodiments, the at least one eleventh mating portion 211 includes a plurality of eleventh mating portions 211. The at least one second mating portion 221 includes a plurality of second mating portions 221. The plurality of eleventh mating portions 211 and the plurality of second mating portions 221 are respectively disposed correspondingly and distributed along the length direction of the housing 100.

[0309] By providing the eleventh matching portion 211 and the first abutting portion 213 on the first sub-air deflector 210, and providing the second matching portion 221 and the second abutting portion 223 on the second sub-air deflector 220, and utilizing the eleventh matching portion 211 to cooperate with the second matching portion 221, and utilizing the first abutting portion 213 to cooperate with the second abutting portion 223, not only can the installation and removal of the first sub-air deflector 210 and the second sub-air deflector 220 be facilitated, but the first sub-air deflector 210 and the second sub-air deflector 220 are also firmly connected, facilitating the manufacture of the first sub-air deflector 210 and the second sub-air deflector 220, and by providing the first stopping portion 212 on the first sub-air deflector 210, the first stopping portion 212 abuts against the first edge 222 to determine the connection position of the first sub-air deflector 210 and the second sub-air deflector 220.

[0310] In some embodiments of the present disclosure, since the first sub-air guide plate 210 and the second sub-air guide plate 220 are detachably connected and are respectively located on the leeward side of the second sub-air guide plate 220, the heat or cold in the conditioned air can be easily transferred to the first sub-air guide plate 210 through the second sub-air guide plate 220, causing the first sub-air guide plate 210 to deform.

[0311] In some embodiments, a heat-insulating material is provided between the first sub-air guide plate 210 and the second sub-air guide plate 220 to prevent the temperature of the second sub-air guide plate 220 from being transferred to the first sub-air guide plate 210 as much as possible, thereby avoiding deformation of the first sub-air guide plate 210.

[0312] For example, as shown in FIG70 , the first air deflector 200 includes a storage cavity 230. The first sub-air deflector 210 and the second sub-air deflector 220 define the storage cavity 230. The storage cavity 230 is located within the first air deflector 200. Insulation material is placed within the storage cavity 230 to prevent the temperature of the second sub-air deflector 220 from being transferred to the first sub-air deflector 210, thereby preventing deformation of the first sub-air deflector 210. For example, the insulation material is a thermal sponge.

[0313] In some embodiments of the present disclosure, the first air deflector 200 is configured as a separate component comprising a first sub-air deflector 210 and a second sub-air deflector 220. The second sub-air deflector 220 is in contact with the conditioned air, allowing the second sub-air deflector 220 to withstand the heat or cold of the conditioned air. In this way, if the second sub-air deflector 220 becomes deformed, only the second sub-air deflector 220 can be repaired or replaced, thereby reducing the cost of repairing or replacing the first air deflector 200.

[0314] It should be noted that the indoor unit 10 is long, and accordingly, the length of the first air outlet 102 along the length direction of the shell 100 and the length of the first air guide plate 200 are also long. It is difficult to achieve smooth rotation of the first air guide plate 200 by only providing support to the two ends of the first air guide plate 200 along the length direction of the shell 100. Since the middle part of the first air guide plate 200 along the length direction of the shell 100 lacks support, the first air guide plate 200 is prone to shaking during rotation, which not only affects the stability of the air outlet, but also generates noise due to the shaking.

[0315] In some embodiments, as shown in Figures 5, 9, and 58, the indoor unit 10 further includes a support member 160. The support member 160 is disposed at the first air outlet 102, and the first air guide plate 200 is rotatably connected to the support member 160, so that the support member 160 provides support for the rotation of the first air guide plate 200.

[0316] In some embodiments, the support member 160 is disposed at the middle portion of the first air outlet 102 along the length direction of the housing 100 so that the support force of the support member 160 on the first air guide plate 200 can be applied to the first air guide plate 200 more evenly.

[0317] The support member 160 is disposed at the second opening 149 and is arranged along a direction intersecting the extension direction of the first air outlet 102. The support member 160 is connected to the outer edges of the second opening 149 extending along the length direction of the housing 100, so the support member 160 can also increase the strength of the second sub-housing 140.

[0318] It should be noted that since the support member 160 is provided at the first air outlet 102 , the length of the support member 160 along the length direction of the housing 100 should not be too large, otherwise it will affect the air flow of the conditioned air. However, if the size is too small, the strength of the support member 160 will be reduced.

[0319] 9 , the indoor unit 10 further includes a second reinforcing rib 161 . The second reinforcing rib 161 is provided on one side of the support member 160 along the length direction of the housing 100 to increase the strength of the support member 160 .

[0320] In some embodiments, as shown in Figures 9, 33, 61, and 62, the indoor unit 10 further includes a support portion 162. A rotating member 201 is connected to the support portion 162. The rotating member 201 is mounted on the second sub-air deflector 220. The support portion 162 is rotatably connected to the second sub-air deflector 220 via the rotating member 201, allowing the support member 160 to support the rotation of the air deflector.

[0321] In some embodiments, as shown in FIG62 , the indoor unit 10 further includes at least one first adapter 206 . The first adapter 206 is provided on the second sub-air deflector 220 , and the rotating member 201 is connected to the first adapter 206 , thereby connecting the rotating member 201 to the second sub-air deflector 220 .

[0322] In some embodiments, the at least one first transition portion 206 includes two first transition portions 206, which are distributed along the length of the housing 100 and define a gap between the two first transition portions 206 along the length of the housing 100. The support portion 162 is disposed within the gap so that the first transition portion 206 can limit the connection position between the support member 160 and the rotating member 201 along the length of the housing 100.

[0323] It should be noted that when the support portion 162 is disposed in the gap, the two first adapter portions 206 are correspondingly disposed on both sides of the support member 160 along the length direction of the housing 100. The first adapter portions 206 are located on the windward side of the air deflector and close to the rotation axis of the air deflector.

[0324] 65 and 66 , the rotating member 201 includes a rotating portion 2010. The rotating portion 2010 is rotatably connected to the supporting portion 162 and the first adapter portion 206, so that the second sub-air deflector 220 is rotatably connected to the supporting portion 162 via the rotating member 201.

[0325] In some embodiments, as shown in Figures 65 and 66, the first adapter portion 206 has a first connection hole, and the rotating portion 2010 is disposed in the first connection hole 106 to rotatably connect the rotating member 201 to the first adapter portion 206. The support portion 162 has a second hole, and the rotating portion 2010 is disposed in the second connection hole to rotatably connect the rotating member 201 to the support portion 162.

[0326] In some embodiments, the opening directions of the first connecting hole and the second connecting hole are respectively arranged along the length direction of the shell 100 , and the axis of the rotating part 2010 is arranged along the length direction of the shell 100 .

[0327] In some embodiments, as shown in Figures 65 and 66 , the rotating member 201 includes a rotating body 2011, which is connected to the second sub-air deflector 220 to enhance the secure connection between the rotating member 201 and the second sub-air deflector 220. It should be noted that the rotating portion 2010 is located at one end of the rotating body 2011 along the length of the housing 100.

[0328] In some embodiments, as shown in FIG. 63 and FIG. 64 , the second sub-air guide plate 220 is provided with a fifth mounting portion 207 , and the fifth mounting portion 207 is used to fix the rotating body 2011 .

[0329] In some embodiments, the first transition portion 206 is disposed near one side of the mounting portion along the length direction of the housing 100 .

[0330] In some embodiments, as shown in FIG66 , the rotating body 2011 is provided with a second fixing portion 2012 . The second fixing portion 2012 is located on a side of the rotating body 2011 facing the second sub-air deflector 220 .

[0331] The second fixing portion 2012 is provided corresponding to the mounting portion. The second fixing portion 2012 is provided on the fifth mounting portion 207 so as to fix the rotating body 2011 and the second sub-air guide plate 220 in connection.

[0332] In some embodiments, the fifth mounting portion 207 is provided with a slot into which the second fixing portion 2012 is engaged, thereby securing the rotating member 201 to the second sub-air deflector 220. This not only increases the secure attachment of the rotating member 201 to the second sub-air deflector 220, but also facilitates removal of the rotating member 201 from the second sub-air deflector 220.

[0333] When the rotating member 201 needs to be disassembled, the second fixing portion 2012 is separated from the fifth mounting portion 207 , so that the rotating member 201 can be disassembled from the second sub-air guide plate 220 .

[0334] In some embodiments, the fifth mounting portion 207 is disposed in the middle portion of the second sub-air deflector 220 along the length direction of the housing 100. The fifth mounting portion 207 is recessed on the windward side of the second sub-air deflector 220 so that when the rotating body 2011 is mounted on the mounting portion, the surface of the rotating body 2011 facing the support member 160 can be roughly aligned with the windward side of the second sub-air deflector 220. This not only maintains the aesthetics of the second sub-air deflector 220, but also prevents the rotating body 2011 from interfering with the rotation of the second sub-air deflector 220.

[0335] In some embodiments, the first adapter portion 206 is disposed on a windward side of the second sub-air deflector 220 .

[0336] In some embodiments, the fifth mounting portion 207, the first adapter portion 206 and the second sub-air guide plate 220 can be formed into an integral part by injection molding. Since the first adapter portion 206 is provided with a first connecting hole, during injection molding, if the first connecting hole is designed to be a full circle, then in order to facilitate the smooth separation of the mold used to form the first connecting hole, the second sub-air guide plate 220 usually needs to be designed with an avoidance space to facilitate demolding. The avoidance space is provided on the windward side of the second sub-air guide plate 220, which will affect the aesthetics of the second sub-air guide plate 220.

[0337] In some embodiments, as shown in FIG. 64 , the first transition portion 206 includes a first transition side wall 2061 and a second transition side wall 2062 , so that the first transition side wall 2061 and the second transition side wall 2062 are used to jointly define a second connecting hole 1414 for demolding during injection molding.

[0338] The first transition side wall 2061 and the second transition side wall 2062 are distributed along the length direction of the housing 100 . The second transition side wall 2062 is located on a side of the first transition side wall 2061 away from the mounting portion along the length direction of the housing 100 .

[0339] The first adapter side wall 2061 is protruding from the windward side of the second sub-air deflector 220 , and the second adapter side wall 2062 is recessed from the windward side of the second sub-air deflector 220 .

[0340] The rotating portion 2010 contacts the first adapter side wall 2061 and the second adapter side wall 2062 , so that the rotating portion 2010 and the first adapter portion 206 are rotatably connected to each other.

[0341] When the rotating part 2010 contacts the first adapter side wall 2061 and the second adapter side wall 2062 respectively, the first adapter side wall 2061 and the second adapter side wall 2062 respectively constrain both sides of the normal direction of the rotating part 2010, so that the rotating part 2010 can be reliably rotatably connected with the first adapter part 206.

[0342] It should be noted that the first adapter side wall 2061 is arranged on the windward side of the protruding second sub-air guide plate 220 .

[0343] In some embodiments, as shown in Figure 64, the second sub-air guide plate 220 has an opening 202 below the first transition side wall 2061, so that the mold used to produce the first transition side wall 2061 can be demolded through the opening 202, and the second transition side wall 2062 is recessed on the windward side of the second sub-air guide plate 220. The mold used to produce the second transition side wall 2062 moves away from the second sub-air guide plate 220 in a direction perpendicular to the windward side of the second sub-air guide plate 220, and can be demolded to manufacture the first transition side wall 2061.

[0344] It should be noted that since at least one first adapter portion 206 includes two first adapter portions 206, when producing the first adapter portion 206 close to the mounting portion, the mold for forming the first connecting hole can move in the direction of the first adapter portion 206 away from the mounting portion, and be demolded from the gap formed by the two first adapter portions 206. Therefore, the first adapter portion 206 close to the fifth mounting portion 207 can be designed as a whole circle without being designed as a split body.

[0345] In some embodiments, the motor shaft of the first motor 240 is also connected to the rotating member 201 , and the motor shaft of the first motor 240 is rotatably connected to the first air guide plate 200 through the rotating member 201 .

[0346] When the motor shaft of the first motor 240 is connected to the second sub-air deflector 220 via the rotating member 201, the rotating portion 2010 is provided with a connecting cavity, and the motor shaft of the first motor 240 is disposed within the connecting cavity, so that the motor shaft of the first motor 240 is connected to the rotating member 201, thereby connecting the motor shaft 512 to the rotating member 201. It should be noted that the connecting cavity is provided in the rotating portion 2010, and the opening of the connecting cavity is provided at the end of the rotating portion 2010 away from the rotating body 2011.

[0347] In some embodiments, as shown in FIG67 , the indoor unit 10 further includes a second adapter 203. The second adapter 203 is provided at one end of the second sub-air guide plate 220 along the length direction of the housing 100.

[0348] In some embodiments, as shown in FIG67 , the indoor unit 10 further includes a third adapter 204. The third adapter 204 is provided at one end of the second sub-air guide plate 220 along the length direction of the housing 100.

[0349] It should be noted that the motor shafts of the two first motors 240 are correspondingly connected to the second adapter part 203 and the third adapter part 204 through the rotating part 201, so that the second adapter part 203 and the third adapter part 204 impose constraints on the corresponding rotating part 2010, thereby increasing the firmness of the connection between the rotating part 201 and the second sub-air guide plate 220.

[0350] In some embodiments, as shown in Figure 72, the support member 160 is protruding from the surface of the second sub-shell 140. On the one hand, it can facilitate the connection between the support member 160 and the first air guide plate 200, and on the other hand, it can increase the firmness of the connection between the support member 160 and the second sub-shell 140.

[0351] It should be noted that the first air guide plate 200 further includes a first assembly portion (first protrusion) 163 . The first assembly portion 163 is provided at the lower end of the support member 160 , and is located on a side of the support member 160 away from the interior of the housing 100 .

[0352] It should be noted that when the first sub-housing 110 is connected to the second sub-housing 140 , the support member 160 may affect the connection between the second sub-housing 140 and the first sub-housing 110 .

[0353] In some embodiments, as shown in Figures 59 and 60, the indoor unit 10 further includes a relief portion 1119 (avoidance). The relief portion 1119 is provided on the first sub-housing 110. The relief portion 1119 is provided corresponding to the first assembly portion 163 to prevent the first assembly portion 163 from interfering with the connection between the second sub-housing 140 and the first sub-housing 110.

[0354] When the first sub-shell 110 is connected to the second sub-shell 140, the first assembly portion 163 is arranged in the avoidance portion 1119. Therefore, when the first sub-shell 110 and the second sub-shell 140 are connected, the connection position of the first sub-shell 110 and the second sub-shell 140 can be determined by arranging the first assembly portion 163 in the avoidance portion 1119.

[0355] In some embodiments, the avoidance portion 1119 is a notch provided in the first sub-housing 110 , and the first assembly portion 163 is provided in the notch to determine the connection position between the second sub-housing 140 and the first sub-housing 110 .

[0356] In some embodiments, the indoor unit 10 further includes a third reinforcing rib 1116 . The third reinforcing rib 1116 is disposed on a side of the first sub-housing 110 facing the second sub-housing 140 , and is disposed on the periphery of the avoidance portion 1119 to increase the strength of the avoidance portion 1119 .

[0357] In some embodiments, the first assembly portion 163 extends to the outer edge of one side of the second sub-housing 140 extending along the length direction of the housing 100 to increase the connection area between the support member 160 and the second sub-housing 140 , thereby increasing the connection strength between the support member 160 and the second sub-housing 140 .

[0358] In some embodiments of the present disclosure, a support member 160 is provided at the second opening 149 to prevent the second opening 149 from being deformed, thereby increasing the strength of the second sub-shell 140, and utilizing the support member 160 to support the rotation of the air guide plate to increase the smoothness of the operation of the air guide plate and reduce the noise generated by the rotation of the air guide plate. Furthermore, the strength of the second sub-shell 140 can be increased without affecting the air outlet effect of the air conditioner, thereby improving the smoothness of the rotation of the air guide plate.

[0359] The first air deflector 200 is positioned at both ends along the length of the housing 100, corresponding to the longitudinal edges of the first air outlet 102. A gap exists between the ends of the first air deflector 200 along the length of the housing 100 and the corresponding edges of the first air outlet 102, allowing for reliable rotation of the first air deflector 200. The two gaps between the two longitudinal ends of the first air deflector 200 and the lateral edges of the first air outlet 102 are approximately the same size along the length of the housing 100, thereby improving the aesthetics of the indoor unit 10.

[0360] In some embodiments, as shown in Figures 62, 64, and 73, the first air deflector 200 further includes a first constraint 205. The first constraint 205 is disposed on a side of the first air deflector 200 that is proximate to the rotation axis of the first air deflector 200. The first constraint 205 is disposed in correspondence with the support member 160. The first constraint 205 adjusts the connection position of the first air deflector 200 with the support member 160 along the length of the housing 100 via the support member 160, thereby adjusting the position of the first air deflector 200 along the length of the housing 100, thereby preventing the first air deflector 200 from shifting along the length of the housing 100.

[0361] When the first air deflector 200 rotates to the target position, the support member 160 adjusts the connection position of the first air deflector 200 and the support member 160 along the length direction of the housing 100 through the first constraint portion 205. The target position refers to the position of the first air deflector 200 when the first constraint portion 205 and the support member 160 are in contact with each other.

[0362] When the first air guide plate 200 rotates until the first constraint portion 205 contacts the support member 160 , the support member 160 adjusts the connection position of the first air guide plate 200 and the support member 160 along the length direction of the housing 100 through the first constraint portion 205 .

[0363] In some embodiments, when the first air guide plate 200 rotates to open the first air outlet 102 at a maximum angle, the first restraining portion 205 contacts the bottom of the support member 160 .

[0364] The first restraining portion 205 is located on a side of the first air guide plate 200 close to the rotation axis of the first air guide plate 200 , so that the first restraining portion 205 can contact the support member 160 when the first air guide plate 200 rotates.

[0365] The first restraining portion 205 is disposed between the two first transition portions 206 along the length direction of the housing 100 .

[0366] In some embodiments, as shown in FIG72 , the support member 160 further includes a first mating portion 164. The first mating portion 164 is located below the support portion 162. The first mating portion 164 corresponds to and cooperates with the first restraining portion 205. The first restraining portion 205 restrains the position of the first mating portion 164 to adjust the connection position of the first air deflector 200 with the support member 160 along the length direction of the housing 100.

[0367] In some embodiments of the present disclosure, the first constraint portion 205 is used to constrain the position of the first matching portion 164 to adjust the connection position of the first air guide plate 200 and the support member 160 along the length direction of the shell 100. This can increase the left and right gaps when the first air guide plate 200 is closed without increasing costs.

[0368] In some embodiments, the first constraint portion 205 includes at least one first surface, and the first surface is located on an inner wall of one side of the first constraint portion 205 disposed along the length direction of the housing 100 .

[0369] In some embodiments, the first matching portion 164 includes a second surface, which is located on a side wall of the first matching portion 164 disposed along the length direction of the housing 100 , and the second surface is disposed corresponding to the first surface.

[0370] In some embodiments, the at least one first surface includes two first surfaces. The two first surfaces are respectively provided on the inner walls of the first constraint portion 205 along the length direction of the housing 100. The two first surfaces together define a defining portion (recess), and the first mating portion 164 is provided within and adapted to the defining portion.

[0371] In some embodiments, the first mating portion 164 includes at least one second surface. For example, the at least one second surface includes two second surfaces. The two second surfaces are correspondingly disposed on two side walls of the first mating portion 164 along the length direction of the housing 100, with the two first surfaces and the two second surfaces being disposed correspondingly.

[0372] It should be noted that there is a certain gap between the first surface and the second surface to increase the reliability of the rotation of the first air guide plate 200 , but it is easy to reduce the positioning accuracy of the first air guide plate 200 .

[0373] In some embodiments, as shown in Figure 73, the first surface and the second surface are respectively inclined surfaces, so that when the first air guide plate 200 moves along the length direction of the shell 100, the first surface and the second surface can contact each other while avoiding affecting the rotation of the first air guide plate 200.

[0374] The distance between the two first surfaces along the length direction of the housing 100 increases as the end of the first constraint portion 205 connected to the first air guide plate 200 moves toward the end of the first constraint portion 205 away from the first air guide plate 200 .

[0375] In some embodiments, the distance between the two second surfaces decreases from the top of the support member 160 toward the bottom of the support member 160 .

[0376] In some embodiments, the two first surfaces define the defining portion to form a predetermined angle, for example, the defining portion is in a V-shaped structure.

[0377] In some embodiments, the two second surfaces also set the first matching portion 164 at a predetermined angle. For example, the first matching portion 164 is in a V-shaped structure.

[0378] In some embodiments, the minimum dimension between the two first surfaces along the length direction of the shell 100 is greater than the minimum dimension between the two second surfaces along the length direction of the shell 100, and the minimum dimension between the two first surfaces along the length direction of the shell 100 is smaller than the maximum dimension between the two second surfaces along the length direction of the shell 100.

[0379] Since the bottom of the support member 160 is located in the gap formed by the two first adapter portions 206, the maximum distance between the two first surfaces along the length direction of the shell 100 is less than or equal to the spacing between the two first adapter portions 206 along the length direction of the shell 100, so that the first surfaces can contact each other with the support member 160.

[0380] The maximum distance between the two second surfaces along the length direction of the housing 100 is less than or equal to the spacing between the two first transition portions 206 along the length direction of the housing 100 , so that the support member 160 can be disposed in the gap formed by the two first transition portions 206 .

[0381] It should be noted that when the first air guide plate 200 is to close the first air outlet 102, the driving motor drives the first air guide plate 200 to rotate until the first constraint part 205 and the support member 160 are in contact with each other, and the two first surfaces of the first constraint part 205 interact with the two second surfaces of the first matching part 164 to adjust the position of the first air guide plate 200 along the length direction of the shell 100, so that when the first air guide plate 200 closes the first air outlet 102, the gaps between the two ends of the first air guide plate 200 relatively set along the length direction of the shell 100 and the two side edges of the first air outlet 102 relatively set along the length direction of the shell 100 can be roughly symmetrically arranged, thereby increasing the aesthetics of the indoor unit 10.

[0382] In this way, by setting a first constraint portion 205 on the first air guide plate 200 and setting a first matching portion 164 on the support member 160, the first constraint portion 205 and the first matching portion 164 cooperate with each other to adjust the connection position of the first air guide plate 200 and the support member 160 along the length direction of the shell 100, thereby preventing the first air guide plate 200 from offsetting along the length direction of the shell 100, and increasing the aesthetics of the indoor unit 10 when the first air guide plate 200 closes the first air outlet 102.

[0383] It should be noted that the support member 160 can not only support the rotation of the first air guide plate 200 and increase the smoothness of the rotation of the first air guide plate 200, but also adjust the setting position of the first air guide plate 200 along the length direction of the shell 100, thereby increasing the reliability of the first air guide plate 200 and the aesthetics of the indoor unit when the first air outlet 102 is closed.

[0384] In some embodiments, as shown in FIG4 , the indoor unit 10 further includes a second air guide plate 600 . The second air guide plate 600 is configured to guide or change the direction of the conditioned air flow and adjust the air volume of the conditioned air. The second air guide plate 600 is rotatably disposed at the first air outlet 102 . The second air guide plate 600 is located on the side of the first air guide plate 200 facing the interior of the housing 100 and is located between the first air guide plate 200 and the heat exchange fan.

[0385] It should be noted that the distance between the second air guide plate 600 and the heat exchange fan is smaller than the distance between the first air guide plate 200 and the heat exchange fan.

[0386] Through the operation of the heat exchange fan, the conditioned air after heat exchange with the heat exchanger 300 is guided to the second air guide plate 600, the second air guide plate 600 guides part of the conditioned air to the first air outlet 102, the second air guide plate 600 guides another part of the conditioned air to the first air guide plate 200, and the conditioned air is guided to the first air outlet 102 by the first air guide plate 200.

[0387] In some embodiments, the second air guide plate 600 guides the air-conditioning wind to blow toward the first air guide plate 200, and uses the first air guide plate 200 to guide the air outlet direction of the air-conditioning wind to prevent the air-conditioning wind from blowing directly onto the human body.

[0388] In some embodiments, the second air guide plate 600 is further configured to increase the air outlet resistance of the air-conditioning air to reduce the air outlet volume, thereby reducing the air outlet noise of the air-conditioning air.

[0389] It should be noted that the second air guide plate 600 rotates around its rotation axis to guide or change the direction of the conditioned air. The rotation axis of the second air guide plate 600 is arranged along the length direction of the first air outlet 102.

[0390] In some embodiments, as shown in FIG90 , the indoor unit 10 further includes a second motor 610. The second motor 610 is connected to the second air deflector 600 and is configured to drive the second air deflector 600. The second motor 610 operates independently of the first motor 240 to cause the first air deflector 200 and the second air deflector 600 to move independently of each other.

[0391] It should be noted that the second air guide plate 600 is connected to a second motor 610, which is connected to one end of the second air guide plate 600 along the length direction of the shell 100, and the other end of the second air guide plate 600 along the length direction of the shell 100 is rotatably connected to the second sub-shell 140 to support the rotation of the second air guide plate 600.

[0392] When the length of the indoor unit 10 increases and the length of the first air outlet 102 along the length direction of the shell 100 increases, the length of the second air guide plate 600 increases. Only the two ends of the second air guide plate 600 along the length direction of the shell 100 are constrained, and the second air guide plate 600 operates with poor stability.

[0393] 91 , the housing 100 further includes a fifth connection portion 1419 . The fifth connection portion 1419 is disposed on the second sub-housing 140 , and is located at an upper edge of the second opening 149 along the length direction of the housing 100 .

[0394] In some embodiments, as shown in FIG91 , the housing 100 further includes a rotating member 620. The rotating member 620 is connected to the fifth connecting portion 1419, which is in turn connected to the second air guide plate 600, such that the second air guide plate 600 is rotatably connected to the fifth connecting portion 1419 via the rotating member 620, thereby enabling the fifth connecting portion 1419 to provide support for the rotation of the second air guide plate 600.

[0395] In some embodiments, as shown in Figures 91 and 98 , the second air deflector 600 further includes a relief portion 630. The relief portion 630 is located on a side of the second air deflector 600 that is close to the rotation axis of the second air deflector 600. The relief portion 630 is disposed corresponding to the fifth connecting portion 1419 to prevent the second air deflector 600 from interfering with the connection between the rotating member 620 and the fifth connecting portion 1419.

[0396] One end of the second air guide plate 600 along the length direction of the shell 100 is connected to the second motor 610. In addition to driving the second air guide plate 600 to rotate, the second motor 610 also provides support for the rotation of the second air guide plate 600; the other end of the second air guide plate 600 along the length direction of the shell 100 is rotatably connected to the second sub-shell 140 to enable the second air guide plate 600 to rotate smoothly.

[0397] In some embodiments, the indoor unit 10 further includes at least one connecting ear. The connecting ear is provided on the second motor 610. The second sub-housing 140 is provided with a third fixing portion 1424. The third fixing portion 1424 corresponds to the connecting ear of the second motor 610. The third fixing portion 1424 and the connecting ear of the second motor 610 each have a connecting hole, and the connecting hole of the third fixing portion 1424 corresponds to the connecting hole of the connecting ear of the second motor 610. Fasteners such as bolts or screws are respectively provided in the connecting hole of the third fixing portion 1424 and the connecting hole of the connecting ear of the second motor 610 to mount the second motor 610 to the second sub-housing 140.

[0398] In some embodiments, at least one connecting ear includes two connecting ears to increase the firmness of the installation of the second motor 610. Accordingly, two third fixing portions 1424 are also provided, and the two third fixing portions 1424 are respectively provided corresponding to the two connecting ears.

[0399] In some embodiments, as shown in Figures 100 and 101 , the housing 100 further includes a tenth mating portion 1420 (third protruding portion). The tenth mating portion 1420 is disposed on the second sub-housing 140 and is located on both sides of the second opening 149 along the length of the housing 100 , so that the second motor 610 can pass through the tenth mating portion 1420 and rotatably connect to the second air guide plate 600 disposed at the second opening 149 .

[0400] As shown in FIG101 , the housing 100 further includes a fifth support portion 1425. The fifth support portion 1425 is disposed on the second sub-housing 140, and is disposed on a side of the second sub-housing 140 away from the heat exchange channel. The fifth support portion 1425 is configured to provide support for the second motor 610 to prevent the second motor 610 from tilting when loaded, thereby causing the position of the second air deflector 600 to deviate from its normal operating position and affect the rotation of the second air deflector 600.

[0401] In some embodiments, the tenth matching portion 1420 is a through opening provided in the second sub-housing 140 , and the tenth matching portion 1420 is provided corresponding to the fifth supporting portion 1425 .

[0402] In some embodiments, the fifth support portion 1425 is centered on the second motor 610 and extends as far as possible along the outline of the motor body 511 of the second motor 610 to enhance the support effect on the motor body 511 and reduce the skewness of the second motor 610 at any angle.

[0403] It should be noted that the second air guide plate 600 has an initial position. When the indoor unit 10 is turned off, the second air guide plate 600 returns to the initial position. The initial position of the second air guide plate 600 also serves as a reference position for the movement of the second air guide plate 600. It should be noted that when the second air guide plate 600 is in the initial position, the indoor unit 10 has a better aesthetic appearance.

[0404] Since the second air guide plate 600 is connected to a second motor 610, the two ends of the second air guide plate 600 along the length direction of the shell 100 are easily offset due to uneven force when the second air guide plate 600 rotates, making it difficult for the second air guide plate 600 to return to its initial position, thereby causing the movement reference position of the second air guide plate 600 to offset, which will not only affect the air guiding effect of the second air guide plate 600, but also affect the aesthetics of the indoor unit 10.

[0405] 92 to 96 , the housing 100 further includes a calibration portion 1418 . The calibration portion 1418 is disposed on the second sub-housing 140 and contacts the second air guide plate 600 to calibrate the position of the second air guide plate 600 .

[0406] For example, as shown in Figure 96, the proofreading portion 1418 is located at the upper edge of the second opening 149. When the second motor 610 drives the second air guide plate 600 to rotate toward the proofreading portion 1418, the proofreading portion 1418 contacts the side of the second air guide plate 600 facing the proofreading portion 1418. The proofreading portion 1418 interacts with the second air guide plate 600 to calibrate or reset the position of the second air guide plate 600.

[0407] It should be noted that the end of the second air guide plate 600 connected to the second motor 610 is the active end, and the end of the second air guide plate 600 away from the second motor 610 is the driven end. The active end drives the driven end to rotate. In this way, the proofreading part 1418 is arranged close to the side of the second sub-shell 140 where the second motor 610 is installed to enhance the calibration effect of the proofreading part 1418 on the second air guide plate 600.

[0408] 97 to 99 , a second matching portion 640 is provided on the side of the second air guide plate 600 facing the calibration portion 1418. The second matching portion 640 cooperates with the calibration portion 1418 to enable the calibration portion 1418 to calibrate and reset the second air guide plate 600.

[0409] In some embodiments, the second mating portion 640 is provided with a third mating surface, and the side of the correction portion 1418 facing the second air guide plate 600 is provided with a fourth mating surface, and the fourth mating surface contacts the third mating surface to correct the position of the second air guide plate 600.

[0410] It should be noted that, when the second air guide plate 600 is in the initial position, the third mating surface and the fourth mating surface are in contact with each other.

[0411] In some embodiments, the second air guide plate 600 can hide the proofreading portion 1418 to prevent the proofreading portion 1418 from affecting the aesthetics of the indoor unit.

[0412] In some embodiments, the calibration portion 1418 protrudes from the surface of the second sub-housing 140 and is integrally formed with the second sub-housing 140 by injection molding. This not only facilitates the arrangement of the calibration portion 1418 but also increases the connection strength between the calibration portion 1418 and the second sub-housing 140.

[0413] By operating the heat exchange fan, the indoor air is introduced into the heat exchange channel from the first air inlet 101, contacts the heat exchanger 300 and exchanges heat to form conditioned air. Part of the conditioned air is guided by the second air guide plate 600 from the first air outlet 102 and output to the room. The other part of the conditioned air is guided by the second air guide plate 600 from the first air outlet 102 and flows to the first air guide plate 200, and is output to the room after passing through the first air guide plate 200.

[0414] When the indoor unit 10 is turned off, the second motor 610 drives the second air guide plate 600 to rotate toward the direction close to the proofreading part 1418, so that the second matching part 640 and the proofreading part 1418 are squeezed and contacted with each other, so that the proofreading part 1418 calibrates and resets the position of the second air guide plate 600. After the second air guide plate 600 is calibrated, the second motor 610 drives the second air guide plate 600 to move to the initial position.

[0415] It should be noted that when the indoor unit 10 is turned off, the second air guide plate 600 needs to be rotated first until the second matching part 640 and the proofreading part 1418 contact each other, so that the proofreading part 1418 calibrates the position of the second air guide plate 600 and then returns to the initial position of the second air guide plate 600.

[0416] The indoor unit 10 can calibrate the position of the second air deflector 600, achieving effective calibration and high reliability. Furthermore, the second air deflector 600 is securely mounted, ensuring smooth operation and excellent airflow guidance. Furthermore, the second motor 610 that drives the second air deflector 600 is securely mounted. Furthermore, the calibration portion 1418 is easy to manufacture, facilitates demolding, and avoids affecting the mold structure.

[0417] The heat exchanger 300 is installed in the housing 100 and is located in the heat exchange channel. After the air in the heat exchange channel contacts the heat exchanger 300, the air is heated by the heat exchanger 300 to form air-conditioned air to meet the cooling or heating needs.

[0418] It should be noted that the heat exchanger 300 is disposed near the first air inlet 101. The conditioned air can be cold air, hot air or normal temperature air.

[0419] 54 , the housing 100 further includes a sixth support portion 1415 . The sixth support portion 1415 is disposed on the second sub-housing 140 and contacts a side of the heat exchanger 300 facing the heat exchange fan to support the heat exchanger 300 .

[0420] It should be noted that the sixth support portion 1415 extends along the length direction of the shell 100 to increase the supporting effect of the sixth support portion 1415 on the heat exchanger 300 .

[0421] In some embodiments, as shown in FIG55 , the indoor unit 10 further includes a second side plate 340. The second side plate 340 is connected to the second sub-housing 140 to secure the heat exchanger 300. For example, the second side plate 340 is connected to one end of the heat exchanger 300 along the length direction of the housing 100.

[0422] In some embodiments, the indoor unit 10 further includes a retaining wall 1417. The retaining wall 1417 is provided on a side of the second sub-housing 140 facing the rear side of the housing 100, and is configured to close the opening of the fourth chamber. An end of the second side plate 340 facing the rear side of the housing 100 abuts against the retaining wall 1417.

[0423] In some embodiments, as shown in FIG55 , the indoor unit 10 further includes a seventh support portion 342 . The seventh support portion 342 is disposed on the second side plate 340 . The seventh support portion 342 is disposed on the side of the second side plate 340 facing the heat exchanger 300 . The seventh support portion 342 is disposed corresponding to the side of the heat exchanger 300 facing the heat exchange fan to support the heat exchanger 300 and increase the reliability of the heat exchanger 300 being mounted on the second sub-housing 140 .

[0424] In some embodiments, as shown in FIG. 55 , the indoor unit 10 further includes a third stopper 341. The third stopper 341 is provided on the second side plate 340 and is located at at least one of the front and rear sides of the heat exchanger 300. The third stopper 341 is configured to limit the position of the heat exchanger 300 and prevent it from moving along the thickness direction of the housing 100. The provision of the third stopper 341 enhances the secure installation of the heat exchanger 300.

[0425] In some embodiments, the third limiting portion 341 is provided on at least one of the side of the heat exchanger 300 facing the front side of the shell 100 and the side of the heat exchanger 300 facing the rear side of the shell 100, and the third limiting portion 341 contacts the heat exchanger 300 or a gap is left between the third limiting portion 341 and the heat exchanger 300 to limit the movement of the heat exchanger 300 along the thickness direction of the shell 100.

[0426] Since the bottom of the heat exchanger 300 contacts the sixth support portion 1415 and the top of the heat exchanger 300 lacks restraining force, the third limiting portion 341 is arranged near the top of the second side plate 340 so that the third limiting portion 341 also restrains the portion of the heat exchanger 300 near the top of the shell 100.

[0427] In this way, by providing the third limiting portion 341 on the second side plate 340 , the third limiting portion 341 is used to limit the top of the heat exchanger 300 and the front-to-back direction of the heat exchanger 300 to prevent the heat exchanger 300 from moving.

[0428] In some embodiments, as shown in FIG56 , the housing 100 further includes a fourth stopper 1118. The fourth stopper 1118 is disposed on the first sub-housing 110. The fourth stopper 1118 is located within the outer cavity and contacts the second side plate 340 to constrain the second side plate 340. The provision of the fourth stopper 1118 enhances the secure connection between the second side plate 340 and the second sub-housing 140.

[0429] Since one end of the second side plate 340 toward the rear side of the shell 100 abuts against the retaining wall 1417, in some embodiments, the fourth limiting portion 1118 is respectively aligned with the side of the second side plate 340 toward the front side of the shell 100 to prevent the second side plate 340 from moving along the thickness direction of the shell 100.

[0430] In some embodiments, the fourth limiting portion 1118 further contacts the top of the second side plate 340 to prevent the second side plate 340 from moving along the height direction of the housing 100 .

[0431] In this way, by setting the fourth limiting portion 1118 on the first sub-shell 110, the fourth limiting portion 1118 is used to limit the front and rear sides of the second side plate 340 and the top of the second side plate 340 to prevent the second side plate 340 from moving and increase the firmness of the installation of the heat exchanger 300.

[0432] In some embodiments, as shown in FIG. 12 , the heat exchanger 300 includes a first section 310 . The first section 310 extends along the length direction of the housing 100 . The first section 310 is disposed near the front side of the housing 100 .

[0433] As shown in FIG12 , the heat exchanger 300 further includes a second section 320 . The second section 320 extends along the length direction of the housing 100 and is disposed close to the first air inlet 101 .

[0434] As shown in FIG12 , the heat exchanger 300 further includes a third section 330 . The third section 330 extends along the length direction of the housing 100 and is disposed near the rear side of the housing 100 .

[0435] It should be noted that the first section 310 and the third section 330 are substantially arranged along the height direction of the housing 100 .

[0436] The second section 320 is connected to the top of the first section 310 and the top of the third section 330 respectively, so that the heat exchanger 300 is roughly a semi-enclosed structure, and the heat exchanger 300 is located on the top of the heat exchange fan.

[0437] The bottoms of the first section 310 and the third section 330 are respectively positioned adjacent to the second sub-housing 140. As shown in FIG54 , the indoor unit 10 further includes two sixth support portions 1415. The two sixth support portions 1415 are respectively positioned on the second sub-housing 140 and extend along the length of the housing 100. The two sixth support portions 1415 correspond to the first section 310 and the third section 330, respectively, and are in contact with each other, thereby providing support to the first section 310 and the third section 330, respectively.

[0438] In this way, by providing the sixth supporting portion 1415 on the second sub-housing 140 and utilizing the sixth supporting portion 1415 to support the heat exchanger 300 , the firmness of the installation of the heat exchanger 300 can be increased.

[0439] In some embodiments of the present disclosure, a third limiting portion 341 is provided to fix the heat exchanger 300, and a fourth limiting portion 1118 is provided to fix the second side plate 340. In this way, the length of the sixth support portion 1415 in contact with the third section 330 can be reduced, and the sixth support portion 1415 in contact with the middle portion of the third section 330 can be in contact with the middle portion to save materials.

[0440] In some embodiments of the present disclosure, the heat exchanger 300 is firmly installed and has a good protection effect on the heat exchanger 300.

[0441] Condensed water is easily generated when air passes through the heat exchanger 300 for heat exchange. The condensed water generated by air heat exchange usually remains on the surface of the heat exchanger 300. The condensed water on the surface of the first section 310 drips along the wall of the first section 310 under the action of gravity, and the condensed water on the surface of the third section 330 drips along its wall under the action of gravity. The height of the end of the second section 320 connected to the first section 310 is smaller than the height of the end of the second section 320 connected to the third section 330, so that the condensed water on the surface of the second section 320 can flow along the wall of the second section 320 to the first section 310 under the action of gravity, and then drip along the wall of the first section 310.

[0442] In some embodiments, as shown in Figures 12 and 13, the housing 100 further includes a water receiving portion 1416. The water receiving portion 1416 is provided on the second sub-housing 140, and the water receiving portion 1416 is provided on a side of the second sub-housing 140 facing the front side of the housing 100 and a side of the second sub-housing 140 facing the rear side of the housing 100, and the water receiving portion 1416 extends along the length direction of the housing 100.

[0443] The water receiving portion 1416 disposed on the front side of the second sub-housing 140 facing the housing 100 is provided corresponding to the first section 310 and is located below the first section 310 .

[0444] The water receiving portion 1416 disposed on the second sub-housing 140 facing the rear side of the housing 100 is provided corresponding to the third section 330 and is located below the third section 330 .

[0445] The condensed water generated by the heat exchanger 300 drops to the water receiving portion 1416 under the action of gravity. The water receiving portion 1416 is connected to a drain pipe so that the condensed water generated by the heat exchanger 300 is discharged from the indoor unit through the drain pipe.

[0446] Since the heat exchanger 300 is arranged in the fourth cavity, the first section 310 is arranged on the side facing away from the heat exchange fan and close to the side of the first sub-shell 110 facing the rear side of the shell 100. When the heat exchanger 300 exchanges heat with the air, condensation water may also be generated on the side of the first sub-shell 110 facing the rear side of the shell 100.

[0447] In some embodiments, as shown in Figures 13 and 14, the housing 100 further includes a flow guide 1117. The flow guide 1117 is provided on a side of the first sub-housing 110 facing the rear side of the housing 100. The flow guide 1117 corresponds to a water receiving portion 1416 provided on the second sub-housing 140 facing the front side of the housing 100, so that condensation water generated on the side of the first sub-housing 110 facing the rear side of the housing 100 gathers on the flow guide 1117 and drips along the flow guide 1117 into the water receiving portion 1416.

[0448] For example, the guide portion 1117 is located above the water receiving portion 1416 provided on the second sub-shell 140 toward the front side of the shell 100, and the guide portion 1117 is tilted downward from the front side of the shell 100 toward the rear side of the shell 100, so that the condensed water dripping on the guide portion 1117 drips onto the water receiving portion 1416 along the guide portion 1117 under the action of gravity.

[0449] It should be noted that the third section 330 is arranged on the side away from the heat exchange fan toward the baffle wall 1417, and the water receiving portion 1416 provided on the second sub-shell 140 toward the rear side of the shell 100 is located below the baffle wall 1417. Therefore, the condensed water generated by the baffle wall 1417 will drip along the baffle wall 1417 to the water receiving portion 1416 provided on the second sub-shell 140 toward the rear side of the shell 100.

[0450] In this way, by setting a guide portion 1117 on the inner wall of the first sub-shell 110 near the first section 310, the guide portion 1117 is set corresponding to the water receiving portion 1416 provided on the second sub-shell 140 facing the front side of the shell 100, so that the condensed water generated on the inner wall of the first sub-shell 110 near the first section 310 can drip from the guide portion 1117 to the water receiving portion 1416.

[0451] By tilting the guide part 1117 and positioning the guide part 1117 above the water receiving part 1416 and with the lower side of the guide part 1117 corresponding to the water receiving part 1416 , it is convenient for the condensed water to drip into the water receiving part 1416 under the action of gravity.

[0452] The heat exchange fan is installed in the housing 100 and located in the heat exchange channel. The heat exchange fan is located on the side of the heat exchanger 300 away from the first air inlet 101 , and the axial direction of the heat exchange fan extends along the length direction of the housing 100 .

[0453] The heat exchange fan operates to draw indoor air into the heat exchange channel from the first air inlet 101. After heat exchange in the heat exchanger 300 to form conditioned air, the conditioned air flows into the room from the first air outlet 102. For example, the heat exchange fan is a cross-flow fan.

[0454] In some embodiments, the indoor unit 10 further includes a display assembly. As shown in Figures 38 to 41, the display assembly includes a display panel 800. The display panel 800 is configured to display information related to the operation of the indoor unit 10 and control information related to the operation of the indoor unit 10, such as the operating mode of the indoor unit 10, the set temperature, the wind speed, and other information.

[0455] In some embodiments, the display panel 800 is further configured to display different colors to enhance the aesthetics of the indoor unit 10 .

[0456] 2 , the display assembly further includes a display box 400 . The display box 400 is disposed near the front side of the housing 100 , and is configured to mount the display panel 800 .

[0457] Since the first sub-housing 110 is a frame structure, when the indoor unit 10 is subjected to a drop test or transported, the display box 400 can easily pass through the first sub-housing 110 and contact the side of the heat exchanger 300 facing the front side of the housing 100, causing damage to the heat exchanger 300.

[0458] 2 , the indoor unit 10 further includes an isolation portion 111. The isolation portion 111 is provided on the first sub-housing 110. By providing the isolation portion 111 between the display box 400 and the heat exchanger 300, damage to the heat exchanger 300 from the display box 400 can be reduced.

[0459] For example, the isolation portion 111 is provided on the first sub-housing 110 and is located on a side of the first sub-housing 110 facing the front side of the housing 100 . The isolation portion 111 is located between the display box 400 and the heat exchanger 300 .

[0460] When the display box 400 is acted upon by an external force and approaches the heat exchanger 300 , the display box 400 first contacts the isolation portion 111 . The isolation portion 111 then generates a reverse force on the display box 400 to prevent the display box 400 from moving further toward the heat exchanger 300 .

[0461] When the reaction force of the isolation portion 111 on the display box 400 is smaller than the external force applied to the display box 400, the display box 400 continues to move toward the heat exchanger 300, and the display box 400 causes the isolation portion 111 to contact the heat exchanger 300. At this time, the external force applied to the display box 400 is partially offset by the reaction force provided by the isolation portion 111, and therefore, the damage to the heat exchanger 300 is relatively small.

[0462] For example, the heat exchanger 300 includes a fin heat exchanger. When the heat exchanger 300 collides with or interacts with other components, the fins are likely to fall over, thereby reducing the heat exchange efficiency of the heat exchanger 300 .

[0463] The isolation portion 111 is provided on the first sub-housing 110 to prevent the display box 400 from directly contacting the heat exchanger 300, thereby preventing the display box 400 from damaging the heat exchanger 300 during a drop test or transportation of the indoor unit.

[0464] In some embodiments, the indoor unit 10 further includes an electric control box, which is disposed in the housing 100 and contains a circuit board, which is electrically connected to the motor via a circuit.

[0465] The display panel 800 is electrically connected to the circuit board in the electric control box. The circuit board is configured to control the display information of the display panel 800, for example, the operation mode of the indoor unit and the set temperature, wind speed and other related information.

[0466] The display panel 800 is disposed close to the electric control box to facilitate the connection of circuit wiring between the display panel 800 and the circuit board.

[0467] The electric control box is arranged at one end of the shell 100 in the length direction. Therefore, the display panel 800 is also arranged at one end of the shell 100 in the length direction. In addition, the display panel 800 is usually arranged on the front side of the shell 100 to facilitate obtaining the display information of the display panel 800.

[0468] In some embodiments, as shown in Figure 42, the third side panel 150 is provided with a light-transmitting portion 152, and the light-transmitting portion 152 is arranged corresponding to the display panel 800 so that the display content of the display panel 800 can be obtained by the user through the light-transmitting portion 152, thereby preventing the shell 100 from blocking the display panel 800 and avoiding the shell 100 from affecting the display effect of the display panel 800.

[0469] In some embodiments, the light-transmitting portion 152 includes a through opening, and the opening direction of the through opening is arranged along the thickness direction of the housing 100 .

[0470] 40 , the display assembly further includes a mounting member 900 . The display panel 800 is mounted on the mounting member 900 , and the mounting member 900 is detachably connected to the third side panel 150 , so that the display panel 800 is mounted on the third side panel 150 .

[0471] 47 , the mounting member 900 includes a third mounting portion 960 . The third mounting portion 960 is disposed corresponding to the light-transmitting portion 152 , and the display panel 800 is disposed on the third mounting portion 960 so that the display content of the display panel 800 can be obtained through the light-transmitting portion 152 .

[0472] In some embodiments, the third mounting portion 960 is a through opening opened in the mounting member 900 , and the opening direction of the through opening is set along the thickness direction of the shell 100 .

[0473] In some embodiments, the display panel 800 is substantially circular in structure, and the mounting member 900 , the light-transmitting portion 152 , and the third mounting portion 960 are also substantially circular in structure.

[0474] It should be noted that one side of the mounting member 900 along the thickness direction of the housing 100 is provided on the front side of the third side plate 150 , and the other side of the mounting member 900 along the thickness direction of the housing 100 is provided inside the housing 100 .

[0475] The mounting member 900 can not only be used to mount the display panel 800 , but also can be used to decorate the third side panel 150 , thereby preventing the third side panel 150 from having its aesthetics reduced due to the provision of the light-transmitting portion 152 .

[0476] In some embodiments, as shown in FIG47 , the indoor unit 10 further includes a stopper 970. The stopper 970 is provided on one side of the mounting member 900 located inside the housing 100. The stopper 970 is located at the edge of the third mounting portion 960. The stopper 970 contacts the display panel 800 and is used to prevent the display panel 800 from detaching from the third mounting portion 960 in a direction toward the front side of the housing 100.

[0477] It should be noted that the blocking portion 970 reduces the inner diameter of the third mounting portion 960 , thereby preventing the display panel 800 from detaching from the third mounting portion 960 from the rear side of the housing 100 to the front side of the housing 100 .

[0478] In some embodiments, as shown in FIG48 to FIG50 , the display assembly further includes at least one second assembly portion 810 (first matching portion) disposed on the periphery of the display panel 800 .

[0479] In some embodiments, as shown in Figures 48 to 50, the display assembly further includes at least one adapter portion 950 (second mating portion). The adapter portion 950 is disposed on the mounting member 900. The adapter portion 950 is disposed on the outer edge of the third mounting portion 960, and the second assembly portion 810 is disposed within the adapter portion 950 to secure the display panel 800 and prevent it from moving freely within the third mounting portion 960. The use of the second assembly portion 810 and the adapter portion 950 to secure the display panel 800 not only allows for a detachable connection between the display panel 800 and the mounting member 900, but also facilitates installation and removal of the display panel 800.

[0480] In some embodiments, the adapter portion 950 includes a groove or a through groove, and the second assembly portion 810 extends into the adapter portion 950. The adapter portion 950 fixes the display panel 800 by applying constraints to the corresponding second assembly portion 810, so that the display panel 800 is connected to the mounting member 900.

[0481] In some embodiments, the at least one second assembly portion 810 includes multiple second assembly portions 810, and the at least one adapting portion 950 includes multiple adapting portions 950. The multiple adapting portions 950 are respectively provided corresponding to the multiple second assembly portions 810 to increase the firmness of the connection between the display panel 800 and the mounting member 900.

[0482] In some embodiments, the plurality of second assembly portions 810 are unevenly distributed along the outer edge of the display panel 800 to position the display panel 800 on the third mounting portion 960 and prevent the display panel 800 from being installed in reverse.

[0483] In some embodiments, the sizes of adjacent second assembly portions 810 are different, and accordingly, the sizes of adjacent adapter portions 950 are also different, so that the second assembly portions 810 cooperate with the corresponding adapter portions 950 to further position the display panel 800 in the installation position of the third installation portion 960.

[0484] The second assembly portion 810 protrudes from the outer edge of the display panel 800 and extends into the adapter portion 950. The maximum distance between the second assembly portion 810 and the center of the display panel 800 is greater than the maximum distance between the adapter portion 950 and the center of the third mounting portion 960. The second assembly portion 810 affects the inner edge of the third mounting portion 960, making it difficult for the display panel 800 or the mounting member 900 to deform. This makes it difficult for the display panel 800 to be installed in the third mounting portion 960. If external force acts on the second assembly portion 810 or the adapter portion 950, causing the second assembly portion 810 to be located within the adapter portion 950, damage to the display panel 800 is likely to occur.

[0485] In some embodiments, as shown in FIG48 , to reduce damage to the display panel 800 when the second assembly portion 810 is positioned on the adapting portion 950, the display assembly further includes a reserved area 801. The reserved area 801 is positioned on the periphery of the display panel 800. Positioning the second assembly portion 810 outside of the reserved area 801 prevents the reserved area 801 from interfering with the inner edge of the third mounting portion 960, thereby reducing damage to the display panel 800 during installation.

[0486] When installing the display panel 800, the display panel 800 is tilted so that the second assembly portion 810 and the adapter portion 950 are respectively arranged in correspondence. At this time, the distance between the reserved area 801 of the display panel 800 and the mounting member 900 along the thickness direction of the housing 100 is greater than the distance between the non-reserved area 801 of the display panel 800 and the mounting member 900 along the thickness direction of the housing 100. After the second assembly portion 810 and the adapter portion 950 are respectively arranged in correspondence, the reserved area 801 is moved along the thickness direction of the housing 100 toward the direction close to the third mounting portion 960 so that the reserved area 801 contacts the corresponding stop portion 970. Since the second assembly portion 810 is not arranged in the reserved area 801, when the reserved area 801 of the display panel 800 is moved along the thickness direction of the housing 100 toward the direction close to the third mounting portion 960, the reserved area 801 can be prevented from affecting the third mounting portion 960, thereby reducing damage to the display panel 800 during installation.

[0487] In some embodiments, the outer diameter of the second assembly portion 810 of the display panel 800 is not smaller than the inner diameter of the third mounting portion 960, so that there is a fitting gap between the display panel 800 and the third mounting portion 960, so that the display panel 800 can be installed in the third mounting portion 960 and reduce damage to the display panel 800 during the installation process.

[0488] It should be noted that although the second assembly portion 810 is not provided in the reserved area 801 of the display panel 800, it is convenient to install the display panel 800 in the third installation portion 960 and the loss suffered by the display panel 800 during the installation process can be reduced. However, due to the lack of constraints between the reserved area 801 of the display panel 800 and the third installation portion 960, it is easy to cause the display panel 800 to be installed loosely.

[0489] In some embodiments, as shown in FIG48 , the display assembly further includes a second assembly portion 810 . The second assembly portion 810 is disposed in the reserved area 801 .

[0490] In some embodiments, as shown in FIG47 , the display assembly further includes a sixth mating portion 910 (elastic portion). The sixth mating portion 910 is disposed on the mounting member 900 and is mated with the second assembly portion 810 to constrain the reserved area 801 of the display panel 800.

[0491] For example, as shown in Figure 47, the sixth mating portion 910 is located at the outer edge of the third mounting portion 960, and the sixth mating portion 910 and the adapter portion 950 are distributed along the circumferential direction of the outer edge of the third mounting portion 960.

[0492] In some embodiments, the distance between the sixth matching portion 910 and the center of the third mounting portion 960 is greater than the distance between the adapting portion 950 and the center of the third mounting portion 960 .

[0493] In some embodiments, the sixth matching portion 910 matches the second assembly portion 810 , so that the sixth matching portion 910 constrains the second assembly portion 810 .

[0516] The following mainly takes the second assembly part 810 including the first assembly part 811, the second assembly part 812, the third assembly part 813, the fourth assembly part 814 and the fifth assembly part 815 as an example to introduce the assembly process of the display panel 800 and the mounting part 900. The first assembly part 811, the second assembly part 812, the third assembly part 813, the fourth assembly part 814 and the fifth assembly part 815 are respectively unevenly distributed along the circumferential direction of the display panel 800, and the first assembly part 811 is arranged in the reserved area 801.

[0517] The installation steps of the display panel 800 include: moving the sixth matching portion 910 along the thickness direction of the shell 100 toward the direction away from the center of the third mounting portion 960 to prevent the sixth matching portion 910 from interfering with the first assembly portion 811, arranging the second assembly portion 812, the third assembly portion 813, the fourth assembly portion 814 and the fifth assembly portion 815 in the corresponding adapter portion 950, and then contacting the reserved area 801 of the display panel 800 with the blocking portion 970, and finally moving the sixth matching portion 910 along the thickness direction of the shell 100 toward the center of the third mounting portion 960, so that the sixth matching portion 910 is matched with the first assembly portion 811, and the sixth matching portion 910 imposes constraints on the first assembly portion 811 to fix the display panel 800, thereby arranging the display panel 800 in the third mounting portion 960.

[0518] The installation steps of the mounting member 900 include: passing the mounting member 900 through the through portion provided on the side of the third side plate 150 facing the rear side of the shell 100, at this time, the extension portion 153 and the second through portion 124 are staggered with each other, rotating the mounting member 900 so that the extension portion 153 is provided in the locking portion, so that the mounting member 900 is connected to the third side plate 150.

[0519] The display panel 800 is installed by providing a mounting member 900 , and the mounting member 900 is detachably connected to the third side panel 150 to achieve installation of the display panel 800 .

[0521] In some embodiments of the present disclosure, a second assembly portion 810 is provided on the periphery of the display panel 800, and an adapter portion 950 is provided on the outer edge of the third mounting portion 960. The second assembly portion 810 and the adapter portion 950 are correspondingly provided to fix the display panel 800 so that the display panel 800 is provided at the third mounting portion 960.

[0522] In some embodiments of the present disclosure, the second assembly portions 810 are unevenly distributed along the periphery of the display panel 800 to position the display panel 800 and prevent the display panel 800 from being installed upside down.

[0523] In some embodiments of the present disclosure, a sixth mating portion 910 is provided on the outer edge of the third mounting portion 960, and the sixth mating portion 910 is provided corresponding to the second assembly portion 810 to prevent the sixth mating portion 910 from interfering with the second assembly portion 810, thereby preventing the display panel 800 from being difficult to install on the third mounting portion 960. When the display panel 800 is installed on the third mounting portion 960, the sixth mating portion 910 constrains the second assembly portion 810 to increase the firmness of the installation of the display panel 800.

[0526] 4 and 5 , the indoor unit 10 further includes at least one blade 500 . The blade 500 is disposed at the first air inlet 101 .

[0527] In some embodiments, at least one blade 500 includes multiple blades 500, and the multiple blades 500 are distributed along the length direction of the shell 100 to guide the air conditioning air from the first air outlet 102 to the direction of the room and increase the air outlet range of the air conditioning air.

[0528] In some embodiments, as shown in Figures 104, 105, and 110, the indoor unit 10 further includes a third motor 510 (motor). The third motor 510 is connected to the blades 500. The third motor 510 is mounted on the second sub-housing 140 and is configured to drive the blades 500 to rotate. This allows the blades 500 to redirect the conditioned air as it passes through the blades and is then directed into the room. This also increases the range of the conditioned air delivered to the room.

[0529] In some embodiments, as shown in Figures 81 and 85, the indoor unit 10 further includes a connecting rod 540. The connecting rod 540 is connected to the vanes 500. The connecting rod 540 extends along the length of the housing 100, and the plurality of vanes 500 are interconnected via the connecting rod 540. The third motor 510 is connected to one end of the connecting rod 540 along the length of the housing 100. The third motor 510 drives the connecting rod 540 to rotate, thereby causing the connecting rod 540 to drive the plurality of vanes 500 to rotate.

[0530] In some embodiments, as shown in Figures 80 to 84 , the indoor unit 10 further includes a mounting plate 530. The blades 500 are rotatably connected to the mounting plate 530. The mounting plate 530 extends along the length of the housing 100, and a plurality of blades 500 are respectively connected to the mounting plate 530.

[0531] In some embodiments, as shown in FIG89 , the blade 500 further includes a first intermediate portion 502 . The first intermediate portion 502 is located near the connecting rod 540 on the blade 500 . The end of the first intermediate portion 502 away from the blade 500 is rotatably connected to the connecting rod 540 . The mounting plate 530 , the first intermediate portion 502 , and the connecting rod 540 together define a four-bar linkage structure. When the third motor 510 drives the connecting rod 540 to move along the length of the housing 100 , the blade 500 rotates under the action of the connecting rod 540 .

[0532] When the connecting rod 540 moves along the length direction of the shell 100, since the blade 500 is rotatably connected to the mounting plate 530, the mounting plate 530 constrains the blade 500, making it difficult for the blade 500 to move along the length direction of the shell 100. However, the connecting rod 540 applies a force to the blade 500 to move along the length direction of the shell 100. Therefore, the blade 500 will rotate so that the end of the first middle portion 502 connected to the connecting rod 540 moves along the length direction of the shell 100 with the connecting rod 540.

[0533] In some embodiments, as shown in FIG89 , the indoor unit 10 further includes a first rotating portion 501 . The first rotating portion 501 is disposed on the blade 500 . The first rotating portion 501 is rotatably connected to the mounting plate 530 . The first intermediate portion 502 , at one end away from the blade 500 , is disposed on the second rotating portion 503 , which is rotatably connected to the connecting rod 540 .

[0534] In some embodiments, as shown in Figures 85 to 88 , the indoor unit 10 further includes a first mounting opening 531. The first mounting opening 531 is provided on the mounting plate 530. The first mounting opening 531 extends through the mounting plate 530 in a direction perpendicular to the direction in which the mounting plate 530 extends. The first rotating portion 501 is provided in the first mounting opening 531 to rotatably connect the blade 500 to the mounting plate 530.

[0535] In some embodiments, as shown in FIG87 , the indoor unit 10 further includes an inserting portion 543. The inserting portion 543 is disposed on the connecting rod 540, and the second rotating portion 503 is disposed on the inserting portion 543, so that the blade 500 is rotationally connected to the connecting rod 540, and the connecting rod 540 drives the blade 500 to rotate. In this way, the blade 500 can be securely connected to the connecting rod 540 for rotation.

[0536] In some embodiments, as shown in FIG89 , the indoor unit 10 further includes an anti-slip portion 504. The anti-slip portion 504 is disposed at an end of the second rotating portion 503 away from the first intermediate portion 502. The anti-slip portion 504 passes through the insertion portion 543 and is disposed on a side of the connecting rod 540 away from the mounting plate 530.

[0537] In some embodiments, the size of the anti-slip portion 504 is adapted to the size of the insertion portion 543 so that the anti-slip portion 504 cannot pass through the insertion portion 543 under the action of external force, thereby increasing the reliability of the connection between the first middle portion 502 and the connecting rod 540, and further increasing the reliability of the connecting rod 540 driving the multiple blades 500 to rotate.

[0538] It should be noted that the size of the second rotating portion 503 is adapted to the size of the inserting portion 543 , so that the second rotating portion 503 can rotate freely in the inserting portion 543 .

[0539] In some embodiments, as shown in FIG87 , the indoor unit 10 further includes a seventh mating portion 541. The seventh mating portion 541 is provided on the connecting rod 540 and extends along the length of the housing 100. The insertion portion 543 is provided at the middle portion of the seventh mating portion 541 along the length of the housing 100.

[0540] The direction perpendicular to the extension direction of the connecting rod 540 in the plane where the side surface of the insertion portion 543 of the connecting rod 540 is located is set as the first direction, and the size of the seventh matching portion 541 along the first direction is smaller than the size of the insertion portion 543 along the first direction. The seventh matching portion 541 increases the size of the insertion portion 543 by causing the connecting rod 540 to elastically deform, so that the anti-slip portion 504 can pass through the insertion portion 543 from the side of the connecting rod 540 toward the mounting plate 530 and is arranged on the side of the connecting rod 540 away from the mounting plate 530.

[0541] In some embodiments, the seventh matching portion 541 is a long hole, the insertion portion 543 is a through hole, and the seventh matching portion 541 is respectively provided at both ends of the insertion portion 543 along the length direction of the shell 100. The size of the long hole along the first direction is smaller than the size of the through hole along the first direction, and the size of the second rotating portion 503 along the first direction is larger than the size of the through hole along the first direction. The two side edges of the long hole along the length direction of the shell 100 are deformed to increase the size of the through hole along the first direction, so that the second rotating portion 503 is set through the through hole.

[0542] In some embodiments, as shown in FIG85 , the indoor unit 10 further includes a first mounting portion 520 . The first mounting portion 520 is connected to the third motor 510 . The first mounting portion 520 is disposed at one end of the connecting rod 540 along the length of the housing 100 , and the third motor 510 drives the connecting rod 540 to rotate via the first mounting portion 520 .

[0543] 88 , the indoor unit 10 further includes a second positioning portion 522 . The second positioning portion 522 is disposed on the first mounting portion 520 , and the motor shaft 512 of the third motor 510 is disposed in the second positioning portion 522 , so as to connect the third motor 510 to the first mounting portion 520 .

[0544] In some embodiments, as shown in FIG88 , the indoor unit 10 further includes a third rotating portion 521. The third rotating portion 521 is disposed on the first mounting portion 520. The third rotating portion 521 is rotatably connected to the mounting plate 530.

[0545] In some embodiments, the third rotating portion 521 is disposed in the first mounting opening 531 so that the first mounting portion 520 is rotatably connected to the mounting plate 530 .

[0546] In some embodiments, as shown in FIG88 , the indoor unit 10 further includes a second intermediate portion 524. The second intermediate portion 524 is disposed at a position distal to the third rotating portion 521 and adjacent to the connecting rod 540. One end of the second intermediate portion 524 distal to the third rotating portion 521 is rotatably connected to the connecting rod 540. The second intermediate portion 524, the connecting rod 540, the first intermediate portion 502, and the mounting plate 530 collectively define a four-bar linkage structure.

[0547] In some embodiments, the third motor 510 drives the connecting rod 540 to move via the first mounting portion 520, so that the connecting rod 540 drives at least some of the plurality of blades 500 to rotate. In this way, the noise reduction performance can be improved.

[0548] It should be noted that the connecting rod 540 converts the rotational motion of the first mounting portion 520 into linear motion of the connecting rod 540 along the length direction of the housing 100 , and the blade 500 converts the linear motion of the connecting rod 540 along the length direction of the housing 100 into rotational motion of the blade 500 .

[0549] 87 , the indoor unit 10 further includes a second mounting opening 544. The second mounting opening 544 is provided on the connecting rod 540 and extends through the connecting rod 540 in a direction perpendicular to the extending direction of the connecting rod 540.

[0550] 88 , the indoor unit 10 further includes a fourth rotating portion 523 . The fourth rotating portion 523 is disposed in the second mounting opening 544 to rotatably connect the first mounting portion 520 to the connecting rod 540 .

[0551] It should be noted that, due to factors such as the second mounting opening 544 being located at one end of the connecting rod 540 along the length direction of the housing 100 and the connecting rod 540 being driven by a third motor 510 , the connecting rod 540 is generally a non-mirror structure.

[0552] In some embodiments, as shown in FIG87 , the connecting rod 540 is provided with a third engaging portion 542 (anti-fouling portion), which is provided on the side of the connecting rod 540 away from the mounting plate 530 to locate the installation position of the connecting rod 540. In order to improve the assembly efficiency of the connecting rod 540 and the blade 500.

[0553] In some embodiments, the third matching portion 542 is disposed on a surface of the protruding connecting rod 540 , and the third matching portion 542 is disposed on an outer edge of the inserting portion 543 .

[0554] When the third motor 510 drives the connecting rod 540 to move until the extension direction of the connecting rod 540 is colinear with the rotation center of the blade 500, the connecting rod 540 is likely to be stuck due to being at a stuck position, resulting in the third motor 510 being unable to drive the connecting rod 540 to move. At this time, the blade 500 will be at a certain angle and unable to rotate. Since the air-conditioning wind will be affected by the blade 500 when passing through it, when the angle of the blade 500 when the connecting rod 540 is stuck is not the required angle, the air outlet direction and air outlet range of the air-conditioning wind may not be required, and the jamming of the connecting rod 540 is also likely to cause damage to the third motor 510.

[0555] In some embodiments of the present disclosure, as shown in Figure 86, by providing a first limiting portion 534 on the movement trajectory of the connecting rod 540, and the first limiting portion 534 is located before the stuck point position of the connecting rod 540 along the movement trajectory of the connecting rod 540, the connecting rod 540 is first contacted with the first limiting portion 534 before moving to the stuck point position, so that the first limiting portion 534 prevents the connecting rod 540 from continuing to rotate, thereby preventing the connecting rod 540 from moving to the stuck point position.

[0556] For example, the first limiting portion 534 is installed on the mounting plate 530 , and the first limiting portion 534 is located between two adjacent blades 500 . The first limiting portion 534 and the two adjacent blades 500 are distributed along the length direction of the housing 100 .

[0557] When the third motor 510 drives the connecting rod 540 to move along the length direction of the housing 100 until it contacts the first limiting portion 534 , the first limiting portion 534 prevents the connecting rod 540 from continuing to move.

[0558] In some embodiments, the rotation center of the blade 500 is defined along the extension direction of the connecting rod 540 to form an extension line, and the card point position is usually located on the extension line. The first limiting portion 534 is located above the extension line, so that the first limiting portion 534 is arranged before the card point position of the connecting rod 540 along the movement trajectory of the connecting rod 540.

[0559] The first limiting portion 534 is located between the first rotating portion 501 and the connecting rod 540 along the first direction, so that the first limiting portion 534 is located before the locking point of the connecting rod 540 along the movement trajectory of the connecting rod 540 .

[0560] In some embodiments, as shown in Figures 80 to 84, when the third motor 510 drives the connecting rod 540 to move along the length direction of the shell 100 toward the two ends of the length direction of the shell 100, the connecting rod 540 will contact the first limiting portion 534. The first limiting portion 534 can not only prevent the connecting rod 540 from moving to the stuck position, but also limit the rotation angle of the blade 500, thereby increasing the reliability of the blade 500.

[0561] It should be noted that the connecting rod 540 and the mounting plate 530 are respectively provided at the first air outlet 102 , which can easily block the air conditioning air from being output from the first air outlet 102 to the room.

The connecting rod 540 and the end of the blade 500 connected to the connecting rod 540 are disposed within the first mounting cavity 1412, and the opening of the first mounting cavity 1412 is closed using a mounting plate 530 to prevent the connecting rod 540 from affecting the airflow of the conditioned air.

[0563] For example, as shown in FIG. 79 , the first installation cavity 1412 is provided at the first air outlet 102 and extends along the length direction of the housing 100 .

[0564] In some embodiments, the first installation cavity 1412 is provided with an installation cavity opening corresponding to the first air outlet 102 , and the installation cavity opening extends along the length direction of the housing 100 . The installation plate 530 is installed on the second sub-housing 140 and is provided at the installation cavity opening.

[0565] In some embodiments, the mounting plate 530 extends along the length of the housing 100 . The end of the blade 500 connected to the connecting rod 540 is disposed in the first mounting cavity 1412 , and the end of the blade 500 away from the connecting rod 540 is disposed at the first air outlet 102 .

[0566] In some embodiments, as shown in Figures 74 to 76, the third motor 510 is located on the side of the second sub-shell 140 away from the heat exchange channel, and an opening is provided on the cavity wall of the first installation cavity 1412 on the side opposite to the installation cavity opening, and the motor shaft 512 of the third motor 510 passes through the opening and is connected to the connecting rod 540.

[0567] In some embodiments, as shown in FIG75 and FIG76 , the housing 100 further includes a card interface 145 . The card interface 145 is provided on the second sub-housing 140 . The card interface 145 is provided on the cavity wall of the first installation cavity 1412 .

[0568] In some embodiments, as shown in Figures 75 and 76, the housing 100 further includes a fourth mating portion 533 (hook). The fourth mating portion 533 is disposed on the mounting plate 530. The fourth mating portion 533 corresponds to the card interface 145 and is disposed within the card interface 145 so that the mounting plate 530 is positioned at the opening of the mounting cavity.

[0569] In some embodiments, the card interface 145 is an opening defined in the wall of the first mounting cavity 1412 .

[0570] In some embodiments, the second sub-housing 140 is provided with a positioning opening, which is arranged corresponding to the first installation cavity 1412 .

[0571] In some embodiments, the mounting plate 530 is provided with a sixth positioning portion 532 , which is provided corresponding to the positioning opening. The sixth positioning portion 532 is provided in the positioning opening to determine the installation position of the mounting plate 530 .

[0572] It should be noted that when installing the mounting plate 530 , the sixth positioning portion 532 is first positioned in the positioning opening, and then the hook portion 533 is positioned in the engaging portion.

[0573] The third motor 510 drives the connecting rod 540 to move along the length of the housing 100 via the first mounting portion 520. The connecting rod 540 causes the plurality of blades 500 to rotate, adjusting the angles of the blades 500 so that the blades 500 guide the conditioned air out of the first air outlet 102 and into the room. When the connecting rod 540 moves to contact the first stopper 534, the first stopper 534 prevents further movement of the connecting rod 540, thereby preventing the connecting rod 540 from reaching a stuck position. When the third motor 510 drives the connecting rod 540 to move along the length of the housing to a second position, the first stopper 534 restricts further movement of the connecting rod 540. The second position refers to the position of the connecting rod 540 when the connecting rod 540 contacts the first stopper 534.

[0574] In some embodiments of the present disclosure, a first installation cavity 1412 is provided at the first air outlet 102, and the connecting rod 540, the blade 500 and the end connected to the connecting rod 540 are provided in the first installation cavity 1412, and the installation cavity opening is closed using the installation plate 530. This not only can hide the connecting rod 540, the blade 500 and the end connected to the connecting rod 540 to maintain the aesthetics of the indoor unit 10, but also can reduce the blocking effect of the connecting rod 540 on the air conditioning wind.

[0575] In some embodiments of the present disclosure, a first limiting portion 534 is provided on the mounting plate 530 so that the connecting rod 540 contacts the first limiting portion 534 before moving to the stuck position, thereby preventing the connecting rod 540 from moving to the stuck position and increasing the reliability of the movement of the connecting rod 540.

[0576] In some embodiments of the present disclosure, a mating portion 542 is provided on the connecting rod 540 to locate the installation position of the connecting rod 540 , thereby increasing the assembly efficiency of the connecting rod 540 and the blade 500 .

[0577] In some embodiments of the present disclosure, an anti-detachment portion 504 is provided to increase the reliability of the blade 500 and the connecting rod 540 , thereby preventing the blade 500 from detaching from the connecting rod 540 during movement of the connecting rod 540 .

[0578] In some embodiments of the present disclosure, the connecting rod 540 and the blade 500 have high working reliability and good wind guiding effect.

[0579] In some embodiments, as shown in FIG. 107 to FIG. 111 , the third motor 510 is located on a side of the second sub-housing 140 away from the heat exchange channel. The third motor 510 includes a motor body 511 , which is mounted on the housing 100 .

[0580] As shown in Figures 111 to 113, the third motor 510 (motor) further includes a motor shaft 512, which is rotatably connected to the motor body 511, and one end of the motor shaft 512 away from the motor body 511 is connected to the connecting rod 540. The motor shaft 512 is connected to the connecting rod 540, and the motor body 511 drives the motor shaft 512 to rotate, so that the motor shaft 512 drives the blade 500 to rotate.

[0581] 113 , the third motor 510 further includes a second mounting portion 513 . The second mounting portion 513 is disposed on the outer periphery of the motor body 511 .

[0582] In some embodiments, as shown in FIG108 , the housing 100 further includes a first connecting portion 1429 . The first connecting portion 1429 is disposed on the second sub-housing 140 . The first connecting portion 1429 and the second mounting portion 513 are connected to each other via fasteners, so that the motor body 511 is mounted on the housing 100 .

[0583] In some embodiments, as shown in FIG105 , the housing 100 further includes a fourth mounting portion 142 . The fourth mounting portion 142 is disposed on the second sub-housing 140 . The third motor 510 is placed on the fourth mounting portion 142 , so that the fourth mounting portion 142 supports the third motor 510 and increases the secureness of the third motor 510 .

[0584] In some embodiments, the fourth mounting portion 142 is disposed on the front side of the second sub-housing 140 , and the fourth mounting portion 142 is located outside the heat exchange channel.

[0585] In some embodiments, as shown in Figure 106, the fourth mounting portion 142 is provided with a second buffer portion 143 (second opening portion), and the second buffer portion 143 is configured to increase the elasticity of the fourth mounting portion 142. The second buffer portion 143 is provided on the wall surface where the fourth mounting portion 142 contacts the third motor 510.

[0586] In some embodiments, the second buffer portion 143 is an opening provided in the fourth mounting portion 142, and the opening direction of the fourth mounting portion of the second buffer portion 143 is arranged to intersect with the axis of the motor shaft 512 of the third motor 510 to prevent other objects from contacting the motor shaft 512 of the third motor 510 through the second buffer portion 143.

[0587] When the indoor unit 10 is subjected to a drop test or transportation, the first sub-shell 110 is subjected to an impact force, and the impact force is transmitted to the fourth mounting portion 142. The fourth mounting portion 142 will undergo elastic deformation under the action of the second buffer portion 143, thereby preventing the second sub-shell 140 from cracking or being damaged. When the second sub-shell 140 undergoes elastic deformation, the supporting effect of the second sub-shell 140 on the first sub-shell 110 is weakened, so that the first sub-shell 110 can undergo applicable elastic deformation, thereby preventing the first sub-shell 110 from cracking or white marks.

[0588] A through portion 124 is formed on the cavity wall of the first installation cavity 1412 on the side opposite to the installation cavity opening. The motor shaft 512 of the third motor 510 passes through the through portion 124 and is connected to the connecting rod 540 .

[0589] The motor shaft 512 is connected to one end of the connecting rod 540 and is provided with a first positioning portion 514 . The first positioning portion 514 is provided corresponding to the second positioning portion 522 . The first positioning portion 514 is provided in the second positioning portion 522 to connect the motor shaft 512 and the connecting rod 540 to each other.

[0590] In some embodiments, the first positioning portion 514 includes at least one fifth mating surface. The fifth mating surface is disposed on the outer peripheral wall of the motor shaft 512 .

[0591] In some embodiments, the second positioning portion 522 includes at least one sixth mating surface, which is disposed corresponding to and mated with the fifth mating surface to connect the motor shaft 512 and the connecting rod 540 to each other.

[0592] In some embodiments, the at least one fifth mating surface includes two fifth mating surfaces, and the two fifth mating surfaces are arranged correspondingly.

[0593] In some embodiments, the at least one sixth mating surface includes two sixth mating surfaces, and the two sixth mating surfaces are respectively arranged corresponding to the two fifth mating surfaces.

[0594] When the third motor 510 is mounted on the second sub-housing 140 and the motor shaft 512 drives the connecting rod 540 to move via the first mounting portion 520, the second mounting portion 513 is disposed correspondingly to the first connecting portion 1429, and the first positioning portion 514 is disposed correspondingly to the second positioning portion 522. Only when the second mounting portion 513 is disposed correspondingly to the first connecting portion 1429, and the first positioning portion 514 is disposed correspondingly to the second positioning portion 522, can the third motor 510 be mounted on the second sub-housing 140 and the motor shaft 512 drive the connecting rod 540 to move via the first mounting portion 520.

[0595] Since the position of the second positioning portion 522 changes with the movement of the connecting rod 540, the setting position of the sixth mating surface in the second positioning portion 522 also changes with the movement of the connecting rod 540. Therefore, in order to facilitate the installation of the third motor 510, the connecting rod 540 is usually moved to the first position so that the second mounting portion 513 is set corresponding to the first connecting portion 1429, and the first positioning portion 514 is set corresponding to the second positioning portion 522, and then the third motor 510 is installed.

[0596] It should be noted that the limit position of the connecting rod 540 is set as the first position, and the limit position of the connecting rod 540 is the position where the connecting rod 540 cannot move further. In this way, it is easy to determine that the connecting rod 540 moves to the first position.

[0597] It should be noted that the blade 500 can be driven to rotate by the connecting rod 540, and the connecting rod 540 can also be driven to move by driving the blade 500 to rotate. When the third motor 510 is installed, the blade 500 is driven to rotate to a position where it can no longer rotate. At this time, the connecting rod 540 also moves to a position where it can no longer move, that is, the connecting rod 540 moves to the first position.

[0598] Since the motor body 511 is rotatably connected to the motor shaft 512 , external force acting on the motor body 511 or the motor shaft 512 can generally cause the motor body 511 and the motor shaft 512 to rotate relative to each other.

[0599] It should be noted that due to reasons such as transportation or manufacturing, the positional relationship between the first positioning portion 514 and the second mounting portion 513 is not completely consistent. Thus, when the connecting rod 540 moves to the first position, the second mounting portion 513 and the first connecting portion 1429, the first positioning portion 514 and the second positioning portion 522 cannot be respectively configured to correspond to each other, thereby making it impossible for the third motor 510 to be installed in the second sub-housing 140.

[0600] In some embodiments, a calibration component (calibration tool) is provided to correct the positional relationship between the first positioning portion 514 and the second mounting portion 513 so that when the connecting rod 540 moves to the first position, the second mounting portion 513 and the first connecting portion 1429, and the first positioning portion 514 and the second positioning portion 522 are simultaneously correspondingly set.

[0601] Since the third motor 510 has various specifications, the calibration components are also designed to have various specifications. Therefore, it is necessary to select the corresponding calibration components according to the specifications of the third motor 510, which will increase the installation time of the third motor 510 and reduce the installation efficiency of the third motor 510.

[0602] In some embodiments of the present disclosure, a calibration part is provided in the second sub-housing 140, and the specifications of the calibration part are set to correspond to the specifications of the third motor 510 installed in the second sub-housing 140, so as to save time in selecting calibration tooling, reduce the installation time of the third motor 510, improve the installation efficiency of the third motor 510, reduce costs, and simplify operation.

[0603] For example, as shown in FIG. 108 , the calibration portion includes a second constraint portion 1426 configured to constrain the motor shaft 512 .

[0604] In some embodiments, the calibration portion includes a first blocking portion 1427 (blocking portion), and the first blocking portion 1427 is configured to limit the rotation of the motor body 511 .

[0605] When the motor shaft 512 interacts with the second constraint portion 1426 and the motor body 511 contacts the first blocking portion 1427, the second mounting portion 513 and the first connecting portion 1429 are correspondingly arranged, and the first positioning portion 514 and the second positioning portion 522 of the connecting rod 540 when the connecting rod 540 is in the first position are also correspondingly arranged.

[0606] When calibrating the third motor 510 , the motor shaft 512 is first made to interact with the second constraint portion 1426 , and the motor body 511 is rotated so as to make the motor body 511 contact the first blocking portion 1427 to achieve calibration of the positional relationship between the first positioning portion 514 and the second mounting portion 513 .

[0607] In some embodiments, as shown in FIG108 , the calibration portion further includes an arcuate portion 1428 . The arcuate portion 1428 is disposed on the first blocking portion 1427 . When the motor body 511 rotates, it rotates along the edge of the arcuate portion 1428 . When the relative positional relationship between the second mounting portion 513 and the first positioning portion 514 matches the relative positional relationship between the first connecting portion 1429 and the second positioning portion 522 , the outer periphery of the motor body 511 abuts against the arcuate portion 1428 .

[0608] In some embodiments, the second constraint portion 1426 defines a defining portion, wherein the motor shaft 512 is disposed inside the defining portion, the motor body 511 is disposed outside the defining portion, and a side of the motor body 511 connected to the motor shaft 512 contacts an outer edge of the defining portion opening.

[0609] In some embodiments, when the motor shaft 512 is provided in the limiting portion, the two fifth mating surfaces are correspondingly arranged along the length direction of the shell 100, and the two fifth mating surfaces are respectively corresponding to the two side walls of the limiting portion along the length direction of the shell 100, and the side walls of the limiting portion interact with the fifth mating surfaces to prevent the motor shaft 512 from rotating synchronously with the motor body 511.

[0610] It should be noted that the minimum distance between the two side walls of the limiting portion is smaller than the diameter of the motor shaft 512. When the first positioning portion 514 is provided on the limiting portion, the side wall of the limiting portion interacts with the fifth mating surface to prevent the motor shaft 512 and the motor body 511 from rotating synchronously.

[0611] It should be noted that the depth of the limiting portion is greater than the length of the motor shaft 512, and the dimension of the motor body 511 toward one end of the limiting portion is greater than the dimension of the outer edge of the limiting portion, so that when the motor shaft 512 is arranged in the limiting portion, the end of the motor body 511 connected to the motor shaft 512 can abut against the outer edge of the limiting portion.

[0612] In some embodiments, the limiting portion includes a first limiting portion. The two fifth matching surfaces are arranged in a one-to-one correspondence with two side walls of the first limiting portion along the length direction of the housing 100.

[0613] In some embodiments, the defining portion further includes a second defining portion. The second defining portion is located above the first defining portion, and the opening size of the second defining portion is larger than the circumferential size of the motor shaft 512 and smaller than the circumferential size of the end of the motor body 511 connected to the motor shaft 512, so that the end of the motor shaft 512 close to the motor body 511 is disposed within the second defining portion.

[0614] It should be noted that the axis of the motor shaft 512 and the axis of the motor body 511 may not be arranged collinearly. For example, the axis of the motor shaft 512 is arranged to deviate from the axis of the motor body 511 .

[0615] In some embodiments, as shown in Figures 108 to 111, the third motor 510 is installed as follows: first, the motor shaft 512 is inserted into the retaining portion, so that the fifth mating surface corresponds to the two side walls of the retaining portion along the length of the housing 100, and the end of the motor body 511 connected to the motor shaft 512 contacts the outer edge of the retaining portion. Then, the motor body 511 is rotated until the motor body 511 contacts the first blocking portion 1427, which prevents further rotation of the motor body 511. At this point, the positional relationship between the first positioning portion 514 and the second mounting portion 513 is aligned. The connecting rod 540 is moved to the first position by the blade 500. At this point, the positional relationship between the second positioning portion 522 and the first connecting portion 1429 corresponds to the positional relationship between the first positioning portion 514 and the second mounting portion 513. The motor body 511 is then installed in the second sub-housing 140, with the motor shaft 512 positioned within the second positioning portion 522. The fifth mating surface is aligned with the sixth mating surface, thereby completing the installation of the third motor 510.

[0616] In some embodiments of the present disclosure, the indoor unit 10 sets a calibration part in the second sub-housing 140 and uses the calibration part to calibrate the positional relationship between the motor shaft 512 of the third motor 510 and the second mounting part 513 to improve the installation efficiency of the third motor 510.

[0617] In some embodiments, as shown in FIG77 , the second sub-housing 140 is provided with a wiring portion 1410 , which is provided on the front side of the second sub-housing 140 and above the second opening 149 , so as to facilitate the wiring of the first wire.

[0619] In some embodiments, the third motor 510 is disposed outside the second cavity 104 , as shown in FIG77 . A through portion 147 (first opening) is provided on the cavity wall of the second cavity 104 near the third motor 510 , and the first wire enters the second cavity 104 through the through portion 147 .

The second cavity 104 is a routing channel for the first wire.

[0621] It should be noted that the through portion 147 is provided at the connection between the protective plate and the second mounting portion, and the first electrical wire enters the second cavity 104 through the through portion 147 .

[0622] The second sub-housing 140 is provided with a fixing member 1411 . The fixing member 1411 is provided on the wiring portion 1410 . The fixing member 1411 is used to constrain the first wire so that the first wire is routed along the wiring portion 1410 .

[0623] In some embodiments, the wiring portion 1410 is disposed on the front side of the second sub-housing 140 , and the fixing member 1411 is used to suspend the first wire.

[0624] In some embodiments, the second wire is also connected to the electric control board through the wiring portion 1410 .

[0625] In some embodiments of the present disclosure, the third motor 510 is installed on the fourth installation portion 142, and the first wire connecting the third motor 510 and the electronic control board enters the second cavity 104 through the through portion 147 and is connected to the electronic control board from the second cavity 104 through the routing portion 1410.

[0626] In some embodiments of the present disclosure, a wiring portion 1410 is provided on the front side of the second sub-housing 140, and the first sub-housing 110 is used to protect and conceal the first wire, thereby preventing external forces from acting on the first wire and causing damage to the first wire. The first wire is passed through the through portion 147 into the second cavity 104, and then connected to the electronic control board through the wiring portion 1410. A fixing member 1411 is provided on the wiring portion 1410 to restrain the first wire, thereby preventing the first wire from being tangled during routing.
