Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a kitchen air conditioner indoor unit and a kitchen air conditioner. Background Technology

[0002] Currently, during the use of kitchen air conditioners, the air blown from the indoor air supply component tends to reach the display box, causing condensation to form inside and affecting the display quality and lifespan. Some technologies, in order to solve this problem, set a greater distance between the display box and the air outlet, with the indoor air supply component connected to the outlet via a duct. This results in the entire kitchen air conditioner occupying a large space, limiting its applicability. Summary of the Invention

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a kitchen air conditioner indoor unit and a kitchen air conditioner, in which the air outlet frame is sealed between the indoor unit chassis and the air outlet panel, so that the air blown from the air supply component is less likely to blow to the display box, reducing the possibility of condensation in the display box, and thus improving the display quality and service life of the display box.

[0004] According to a first aspect of the present invention, an indoor unit of a kitchen air conditioner includes an indoor unit chassis, an air supply component, an air outlet panel, an air outlet frame, and a display box. The air supply component is disposed on the upper side of the indoor unit chassis, and the air outlet panel is disposed on the lower side of the indoor unit chassis and forms an air outlet. A first connecting port is formed on the indoor unit chassis, connecting the air supply component and the air outlet. The air outlet frame is disposed at the air outlet and forms a second connecting port, connecting the first connecting port and the air outlet. The air outlet frame is sealed between the indoor unit chassis and the air outlet panel, so that a first receiving cavity located on the outer periphery of the air outlet frame is defined between the air outlet frame, the indoor unit chassis, and the air outlet panel. The portion of the air outlet panel corresponding to the first receiving cavity has a display area, and the display box is received in the first receiving cavity and is opposite to the display area.

[0005] According to an embodiment of the present invention, the air outlet frame of the indoor unit of the kitchen air conditioner is sealed between the chassis of the indoor unit and the air outlet panel, so that the air blown from the air supply component is not prone to leakage from the first connection port and the second connection port. This ensures that the air blown from the air supply component can only pass through the first connection port, the second connection port and the air outlet in sequence to be blown into the external environment. That is, the air blown from the air supply component is not likely to blow to the display box, reducing the possibility of condensation in the display box. This facilitates the improvement of the display quality and service life of the display box and helps to improve the stability of the operation of the indoor unit of the kitchen air conditioner. At the same time, due to the above-mentioned air outlet frame, the possibility of condensation in the display box is reduced, making the placement of the display box more flexible.

Detailed Implementation

[0076] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0077] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0078] Hereinafter, with reference to the accompanying drawings, a kitchen air conditioner indoor unit 100 according to a first aspect embodiment of the present invention will be described.

[0079] like Figures 1-5 As shown, the indoor unit 100 of the kitchen air conditioner includes: an indoor unit chassis 1, an air supply component 2, an air outlet panel 3, an air outlet frame 4, and a display box 5. The air supply component 2 is located on the upper side of the indoor unit chassis 1, and the air outlet panel 3 is located on the lower side of the indoor unit chassis 1. The air outlet panel 3 has an air outlet 30. The indoor unit chassis 1 has a first connecting port 10 connecting the air supply component 2 and the air outlet 30. The air outlet frame 4 is located at the air outlet 30 and has a second connecting port 40 connecting the first connecting port 10 and the air outlet 30. The air outlet frame 4 is sealed between the indoor unit chassis 1 and the air outlet panel 3 so that a first receiving cavity 11 located on the outer periphery of the air outlet frame 4 is defined between the air outlet frame 4, the indoor unit chassis 1, and the air outlet panel 3. The portion of the air outlet panel 3 corresponding to the first receiving cavity 11 has a display area 31. The display box 5 is received in the first receiving cavity 11 and the display box 5 is opposite to the display area 31.

[0080] It is understandable that the air outlet panel 3 is located on the lower side of the indoor unit chassis 1, and the air outlet panel 3 has an air outlet 30. In air conditioning design, the air outlet 30 usually needs to be set facing the user. Therefore, the lower side of the kitchen air conditioner indoor unit 100 is the side facing the user, and the upper side of the kitchen air conditioner indoor unit 100 is the side away from the user.

[0081] As can be seen, the air outlet frame 4 is sealed between the indoor unit chassis 1 and the air outlet panel 3. For example, the air outlet frame 4 and the indoor unit chassis 1 are sealed by a stop structure, or the air outlet frame 4 and the indoor unit chassis 1 are sealed by a sealing element. The air outlet frame 4 and the air outlet panel 3 are sealed by a stop structure, or the air outlet frame 4 and the air outlet panel 3 are sealed by a sealing element. This makes it difficult for the air blown out from the air supply component 2 to leak from the assembly gap between the air outlet frame 4 and the indoor unit chassis 1, and also makes it difficult for the air to leak from the assembly gap between the air outlet frame 4 and the air outlet panel 3. That is, the air blown out from the air supply component 2 is not likely to leak from the first connecting port 10 and the second connecting port 40, so that the air blown out from the air supply component 2 can be blown into the external environment in sequence through the first connecting port 10, the second connecting port 40 and the air outlet 30, so that the airflow path is clearer.

[0082] Furthermore, when the kitchen air conditioner indoor unit 100 is running in cooling mode, the temperature difference between the air blown from the air supply component 2 and the outside environment is large. Due to the setting of the aforementioned air outlet frame 4, the air duct of the kitchen air conditioner indoor unit 100 can be separated from the first receiving cavity 11, so that the air blown from the air supply component 2 is less likely to blow to the display box 5, reducing the possibility of condensation in the display box 5, which is conducive to improving the display quality and service life of the display box 5, and is beneficial to improving the operational stability of the kitchen air conditioner indoor unit 100. Therefore, since the problem of condensation in the display box 5 is improved, the distance between the display box 5 and the air outlet 30 is not easily limited by the above-mentioned problem and can be set relatively far, which is conducive to improving the problem of the large space occupied by the kitchen air conditioner 200 to a certain extent. For example, the kitchen air conditioner indoor unit 100 in this embodiment of the application does not need to be equipped with a duct connecting the air supply component 2 and the air outlet 30.

[0083] The display box 5 is located in the first receiving cavity 11 on the outer periphery of the air outlet frame 4. The part of the air outlet panel 3 corresponding to the first receiving cavity 11 has a display area 31. The display box 5 is housed in the first receiving cavity 11 and the display box 5 is opposite to the display area 31. The display box 5 can display information through the display area 31. For example, the display area 31 can be thinned so that the display box 5 can better display the operating information of the kitchen air conditioner indoor unit 100 through the display area 31. The above-mentioned setting position of the display box 5 can make full use of the empty space between the air outlet frame 4, the indoor unit chassis 1 and the air outlet panel 3, so that the structure of the kitchen air conditioner indoor unit 100 is more compact and it is easy to realize the miniaturization design of the kitchen air conditioner indoor unit 100.

[0084] In related technologies, the air blown from the air supply component can easily reach the display box, causing condensation to easily form inside the display box. To reduce the possibility of condensation, the distance between the display box and the air outlet frame is usually set to be large, which affects the layout of the kitchen air conditioner indoor unit and is not conducive to the miniaturization design of the kitchen air conditioner indoor unit. However, in the kitchen air conditioner indoor unit 100 of this application, the air outlet frame 4 is sealed between the indoor unit chassis 1 and the air outlet panel 3, so that the air blown from the air supply component 2 is less likely to reach the display box 5, reducing the possibility of condensation forming inside the display box 5. This allows for more flexible placement of the display box 5, which can be placed adjacent to the air outlet frame 4, making the structure of the kitchen air conditioner indoor unit 100 more compact and facilitating the miniaturization design of the kitchen air conditioner indoor unit 100.

[0085] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the indoor unit chassis 1 includes a first chassis 12 and a second chassis 13. The first chassis 12 is stacked on the lower side of the second chassis 13. The first chassis 12 is located between the second chassis 13 and the air outlet panel 3. A first connecting port 10 is formed on the second chassis 13. An installation port 12a is formed on the first chassis 12 opposite to the first connecting port 10. The air outlet frame 4 is located at the installation port 12a. At least one of the first chassis 12 and the second chassis 13 is sealed to the air outlet frame 4. A first receiving cavity 11 is defined between the air outlet panel 3 and the first chassis 12.

[0086] As can be seen, by setting up the first chassis 12 and the second chassis 13, the first chassis 12 will not directly contact the condensate generated by the indoor unit 100 of the kitchen air conditioner. The first receiving cavity 11 is located between the air outlet panel 3 and the first chassis 12, which reduces the impact of the condensate on the temperature of the first chassis 12. Since the temperature of the first chassis 12 will not be too low, condensation is less likely to form on the inner surface of the first receiving cavity 11. This further reduces the impact of condensation on the display box 5, improves the display quality and lifespan of the display box 5. Simultaneously, the installation port 12a facilitates avoidance of the air outlet frame 4, ensuring that the first chassis 12 does not easily affect the air outlet. For example, the first chassis 12 can be a sheet metal part, while the second chassis 13 can be a plastic part.

[0087] In addition, at least one of the first chassis 12 and the second chassis 13 is sealed to the air outlet frame 4 so that the air blown from the air supply component 2 is less likely to leak from the assembly gap between the air outlet frame 4 and the indoor unit chassis 1, reducing the possibility of condensation in the display box 5 and facilitating the improvement of the stability of the operation of the kitchen air conditioner indoor unit 100.

[0088] It is understandable that only the first chassis 12 is sealed to the air outlet frame 4, or only the second chassis 13 is sealed to the air outlet frame 4, or both the first chassis 12 and the second chassis 13 are sealed to the air outlet frame 4. All of these configurations can separate the airflow channel from the first receiving cavity 11 through the air outlet frame 4. In particular, when the first chassis 12 and the second chassis 13 are respectively sealed to the air outlet frame 4, it facilitates multi-stage sealing between the airflow channel and the first receiving cavity 11. Therefore, the above configurations can effectively prevent airflow leakage to the display box 5, thereby improving the display quality and lifespan of the display box 5.

[0089] The first chassis 12 has a downward-facing clearance groove 12b on its lower side. The air outlet panel 3 is covered by the clearance groove 12b to define a first receiving cavity 11 between the air outlet panel 3 and the first chassis 12. The display box 5 can then be located within the clearance groove 12b, making fuller use of the empty space between the indoor unit chassis 1 and the air outlet panel 3. This makes the structure of the kitchen air conditioner indoor unit 100 more compact and facilitates the miniaturization design of the kitchen air conditioner indoor unit 100. Furthermore, the clearance groove 12b eliminates the need for the air outlet panel 3 to make other adjustments to accommodate the display box 5, thus simplifying the structure of the air outlet panel 3 and facilitating its manufacturing. For example, the air outlet panel 3 can be a flat plate structure, with the flat plate air outlet panel 3 covering the clearance groove 12b to define the first receiving cavity 11 for accommodating the display box 5.

[0090] like Figures 1-5As shown, in some embodiments, the kitchen air conditioner indoor unit 100 further includes a first insulation member 14, which is disposed between the first chassis 12 and the second chassis 13, and at least a portion of the first insulation member 14 is vertically opposite to the first receiving cavity 11. The first insulation member 14 can increase the thermal resistance between the first chassis 12 and the second chassis 13, making it difficult for the temperature of the second chassis 13 to be transferred to the first receiving cavity 11, further reducing the possibility of condensation in the first receiving cavity 11, and facilitating the improvement of the display quality and service life of the display box 5. For example, the kitchen air conditioner indoor unit 100 also includes an indoor heat exchanger 61 and a water receiving tray 15, which is integrally formed on the second chassis 13. The water receiving tray 15 is used to collect the condensate generated by the indoor heat exchanger 61. The temperature of the condensate is usually significantly different from that of the outside environment. By providing the first insulation member 14 between the first chassis 12 and the second chassis 13, the condensate is prevented from being transferred to the first receiving cavity 11. The temperature of the water is not easily transmitted to the first receiving cavity 11, thereby reducing the possibility of condensation in the display box 5; and / or, the peripheral wall of the mounting port 12a is located radially outside the peripheral wall of the first connecting port 10, so the radial dimension of the mounting port 12a is larger than the radial dimension of the first connecting port 10. The upper and lower ends of the air outlet frame 4 are respectively sealed to the second chassis 13 and the air outlet panel 3. The outer peripheral wall of the air outlet frame 4 is sealed to the peripheral wall of the mounting port 12a. That is, the air outlet frame 4 is simultaneously sealed at the first connecting port 10 and the mounting port 12a. The airflow blown out from the air supply component 2 can sequentially pass through the first connecting port 10, the mounting port 12a, the second connecting port 40 and the air outlet 30 to the external environment. Through the above-mentioned arrangement of the air outlet frame 4, the air outlet frame 4 can achieve double sealing, so as to further reduce the possibility of airflow leakage from the gap between the air outlet frame 4 and the internal chassis 1, and reduce the possibility of condensation in the display box 5.

[0091] It can be understood that the air supply component 2 may include one or more indoor fans 20. The air outlet of the indoor fan 20 and the first connecting port 10 of the indoor unit chassis 1 are set in a one-to-one correspondence. When there is one indoor fan 20, there is one first connecting port 10 of the indoor unit chassis 1. When there are multiple indoor fans 20, there are multiple first connecting ports 10 on the indoor unit chassis 1. The air outlets of multiple indoor fans 20 and the first connecting ports 10 of the indoor unit chassis 1 are set in a one-to-one correspondence. The peripheral wall of the mounting port 12a is located radially outside the peripheral wall of the first connecting port 10. It can be understood that the peripheral wall of the mounting port 12a is located radially outside the peripheral wall of all the first connecting ports 10.

[0092] Optionally, the first insulation component 14 is insulation foam or insulation sponge. Both insulation foam and insulation sponge have good thermal insulation performance, and both insulation foam and insulation sponge have good deformation ability, making it easy to adapt to different installation environments.

[0093] like Figure 1 , Figure 6 and Figure 7 As shown in some embodiments, the clearance groove 12b is open on the side facing the mounting port 12a to communicate with the mounting port 12a. The kitchen air conditioner indoor unit 100 also includes a second insulation member 41, which is disposed on the outer peripheral wall of the air outlet frame 4, and the second insulation member 41 is at least disposed on the side of the air outlet frame 4 facing the first receiving cavity 11.

[0094] For example, the second insulation member 41 is configured as an open annulus, and the second insulation member 41 at least partially surrounds the side of the air outlet frame 4 facing the first receiving cavity 11; or the second insulation member 41 is configured as a closed annulus, and the second insulation member 41 surrounds the periphery of the air outlet frame 4; or the second insulation member 41 is configured as a strip, and the second insulation member 41 is provided on the side of the air outlet frame 4 facing the first receiving cavity 11. Thus, the second insulation member 41 can increase the thermal resistance between the second connecting port 40 and the clearance groove 12b, and can reduce the impact of the airflow flowing through the air outlet frame 4 on the first receiving cavity 11. For example, when the kitchen air conditioner indoor unit 100 is running in cooling mode, the airflow temperature blown out through the air outlet frame 4 is low. By setting the second insulation member 41, the temperature of the airflow is not easily conducted to the first receiving cavity 11, so as to reduce the impact of the airflow on the first receiving cavity 11, which helps to reduce the possibility of condensation in the display box 5.

[0095] It should be noted that the term "ring" in this article is interpreted broadly, meaning it is not limited to "circular rings," but can also include "polygonal rings," etc. Furthermore, "ring" includes open rings (i.e., non-closed rings, such as C-shaped, U-shaped, Ω-shaped, etc.) and closed rings.

[0096] The second insulation component 41 abuts against the peripheral wall of the mounting port 12a, making the contact between the second insulation component 41 and the air outlet frame 4 and the first chassis 12 more compact. This makes the setting position of the second insulation component 41 more stable during use, providing a more stable temperature insulation effect. The second insulation component 41 also plays a certain sealing role, allowing the air outlet frame 4 to achieve a sealed fit with the first chassis 12 through the second insulation component 41. The aforementioned setting position of the second insulation component 41 allows it to undergo a certain deformation during the assembly process of the air outlet frame 4 and the first chassis 12. The second insulation component 41 can more fully fill the gap between the mounting port 12a and the air outlet frame 4, making it less likely for airflow to leak through the assembly gap between the air outlet frame 4 and the first chassis 12, further reducing the possibility of condensation inside the display box 5.

[0097] Optionally, the second insulation component 41 is insulation foam or insulation sponge.

[0098] like Figures 8-10As shown, in some embodiments, the air outlet frame 4 is provided with fasteners 42, which pass through the air outlet frame 4 and are detachably connected to the first chassis 12. The fasteners 42 are spaced apart on the outer periphery of the mounting port 12a. The kitchen air conditioner indoor unit 100 also includes a cover plate 43, which is movably connected to the air outlet frame 4. The cover plate 43 can be switched between a first state of covering the fasteners 42 and a second state of avoiding the fasteners 42. The cover plate 43 is exposed to the air outlet 30.

[0099] As can be seen, the fastener 42 passes through the air outlet frame 4 and is detachably connected to the first chassis 12, that is, the air outlet frame 4 and the indoor unit chassis 1 are detachably connected, so as to make the maintenance of the air outlet frame 4 more convenient; the fastener 42 is spaced apart on the outer periphery of the mounting port 12a, so that the fastener 42 will not affect the fitting of the air outlet frame 4 to the mounting port 12a, making the assembly of the air outlet frame 4 simpler.

[0100] Furthermore, the cover plate 43 is movably connected to the air outlet frame 4, for example, the cover plate 43 is rotatably connected to the air outlet frame 4, so that the cover plate 43 can be switched between a first state covering the fastener 42 and a second state avoiding the fastener 42. The cover plate 43 is exposed to the air outlet 30, so that the user can directly see the cover plate 43 through the air outlet 30, thereby controlling the cover plate 43 to switch between the first state and the second state, which is convenient to meet different usage conditions of the kitchen air conditioner indoor unit 100. For example, when it is necessary to disassemble or assemble the air outlet frame 4, the user can move the cover plate 43 from the first state through the air outlet 30. Switching to the second state allows users to directly see the fastener 42 through the air outlet 30, making it easier for users to install and remove the fastener 42 and improving the efficiency of installing and removing the air outlet frame 4. When it is not necessary to install or remove the air outlet frame 4, the cover 43 can be kept in the first state. The cover 43 can cover the fastener 42, so that when the kitchen air conditioner indoor unit 100 is used in the kitchen, oil stains are less likely to come into contact with the fastener 42, which facilitates the subsequent installation and removal of the air outlet frame 4. At the same time, users cannot directly see the fastener 42, which helps to improve the overall aesthetics of the kitchen air conditioner indoor unit 100.

[0101] In some embodiments of this application, after the air outlet frame 4 is fixed to the air outlet panel 3, the air outlet frame 4 and the indoor unit chassis 1 are assembled. The air outlet frame 4 can be connected to the indoor unit chassis 1 by fasteners 42. At this time, the fasteners 42 can also play a part in fixing the air outlet panel 3, so that the setting position of the air outlet panel 3 is more stable. Optionally, the fasteners 42 are bolts, studs, or screws, so as to make the disassembly and assembly of the air outlet frame 4 and the indoor unit chassis 1 more convenient.

[0102] In some embodiments, such as Figure 3 and Figure 4As shown, a mounting groove 12c is formed on the lower side of the indoor unit chassis 1, which communicates with the clearance groove 12b. The mounting groove 12c is connected to or separated from the clearance groove 12b, and the mounting groove 12c is located on the outer periphery of the mounting opening 12a (e.g., as shown). Figure 3 As shown, the mounting port 12a has mounting grooves 12c on both sides of its length direction. A portion of the air outlet frame 4 is accommodated in the mounting grooves 12c, which facilitates the limiting of the air outlet frame 4 through the mounting grooves 12c, making it easier to fix the air outlet frame 4 to the indoor unit chassis 1. Furthermore, the mounting grooves 12c and the clearance grooves 12b can be processed together, simplifying the processing steps of the indoor unit chassis 1. The installation grooves 12c also help improve the structural strength of the indoor unit chassis 1. For example, the mounting grooves 12c are formed on the lower side of the first chassis 12. The air outlet frame 4 is provided with fasteners 42, which pass through the air outlet frame 4 and are detachably connected to the first chassis 12. The fasteners 42 are provided corresponding to the bottom wall of the mounting grooves 12c. It can be understood that the length direction of the mounting port 12a is the length direction of the air outlet frame 4 or the length direction of the air outlet 30. In this application, the width direction of the air outlet frame 4 is the width direction of the air outlet 30.

[0103] like Figure 5 and Figure 6 As shown, in some embodiments, the air outlet panel 3 also forms a stop protrusion 39, which is located on the outer periphery of the air outlet 30. A through hole 4d is formed on the side wall of the air outlet frame 4. The stop protrusion 39 is adapted to be limited and engaged with the lower part of the through hole 4d wall of the air outlet frame 4 through the through hole 4d. Through the cooperation of the stop protrusion 39 and the through hole 4d, the assembly of the air outlet frame 4 and the air outlet panel 3 is made more convenient, the setting position of the air outlet frame 4 and the air outlet panel 3 is more stable, the air outlet frame 4 and the air outlet panel 3 are less prone to misalignment, and the stability of the kitchen air conditioner indoor unit 100 is improved.

[0104] like Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments, the display box 5 is disposed near the air outlet 30 so that both the air outlet 30 and the display box 5 are vertically opposite to the air supply component 2.

[0105] As can be seen, the air outlet 30 and the air supply component 2 are arranged vertically opposite each other, so that the airflow blown from the air supply component 2 can flow directly to the air outlet 30, and then blown from the air outlet 30 to the outside environment, making the airflow path clearer. In related technologies, the air supply component and the air outlet are arranged horizontally at intervals, so that the air blown from the air supply component needs to go through the air duct to change its flow direction, and then blown to the outside environment through the air outlet. However, in this application, the air outlet 30 and the air supply component 2 are arranged vertically opposite each other, so that the airflow blown from the air supply component 2 can flow directly to the air outlet 30 without the need for an air duct. This makes the structure of the kitchen air conditioner indoor unit 100 more compact, which is conducive to the miniaturization design of the kitchen air conditioner indoor unit 100. Moreover, the condensation problem of the display box 5 is improved. The display box 5 can be set near the air outlet 30, which helps to save the overall space occupied by the kitchen air conditioner indoor unit 100.

[0106] like Figures 11-13 As shown, in some embodiments, the display box 5 includes a box body 50, a display module 51, and a box cover 53. The box body 50 is fixed to the air outlet panel 3 and is open on the side of the box body 50 facing the air outlet panel 3. The box cover 53 is sealed on the open side of the box body 50, and the box cover 53 and the box body 50 define a second receiving cavity 59. The display module 51 is received in the second receiving cavity 59. The box cover 53 is located between the box body 50 and the air outlet panel 3, and the box cover 53 has a hollowed-out display portion 54.

[0107] As can be seen, the sealing cover 53 is located on the open side of the box body 50 (for example, after the cover 53 is inserted into the box body 50, the edge of the cover 53 and the box body 50 are sealed with glue), providing a relatively sealed environment for the display module 51, so that the operation of the display module 51 is not easily affected by the external environment, and it is easy to improve the stability of the operation of the display module 51.

[0108] In addition, the cover 53 has a cutout display section 54, through which the display module 51 can display different information. For example, the cutout display section 54 includes a cutout number display section 54a and a cutout pattern display section 54b. The cutout display section 54 is opposite to the display area 31. The display module 51 can display different operating information of the kitchen air conditioner indoor unit 100 through the cutout number display section 54a and the cutout pattern display section 54b, such as the operating temperature and operating mode of the kitchen air conditioner indoor unit 100.

[0109] Furthermore, the display box 5 also includes a transparent sealing element 52, which is sandwiched between the box cover 53 and the air outlet panel 3, and seals the perforated display portion 54. That is, the transparent sealing element 52 seals between the box cover 53 and the air outlet panel 3. The transparent sealing element 52 can further reduce the possibility of condensate in the first receiving cavity 11 contacting the display module 51. For example, if air blown from the air supply component 2 leaks into the first receiving cavity 11 under certain circumstances, the transparent sealing element 52 reduces the possibility of condensate contacting the display module 51 from the perforated display portion 54. To improve the stability of the display module 51, the transparent seal 52 is sealed between the cover 53 and the air outlet panel 3. When the cover 53 and the air outlet panel 3 are assembled, the transparent seal 52 can be subjected to a certain compressive force, which makes it easier to fill the gap between the cover 53 and the air outlet panel 3 more fully, so that the transparent seal 52 has a better sealing effect. At the same time, due to the compressive force of the cover 53 and the air outlet panel 3, the transparent seal 52 is more stable in its setting position and is less prone to displacement, which helps to improve the stability of the operation of the kitchen air conditioner indoor unit 100.

[0110] It is understood that in the embodiments of this application, the transparent sealing member 52 may be configured such that at least the portion of the transparent sealing member 52 opposite to the hollow display portion 54 is transparent, so that the light of the display module 51 can be displayed through the transparent sealing member 52 after passing through the hollow display portion 54.

[0111] like Figure 12 As shown, in some embodiments, the box body 50 has a plurality of stop portions 58 protruding on the side facing the box cover 53. The plurality of stop portions 58 are used to support the display module 51, so that the setting position of the display module 51 in the second receiving cavity 59 is more stable, which facilitates the improvement of the stability of the operation of the display module 51.

[0112] like Figure 13 As shown, in some embodiments, the cover 53 has multiple hollow display sections 54, and the transparent sealing member 52 includes multiple light-transmitting parts and multiple light-shielding parts. Each light-shielding part is arranged around its corresponding transparent part, and the light-transmitting part is arranged opposite to the hollow display section 54. When the display module 51 emits light through the hollow display section 54, the transparent part is less likely to affect the normal light emission of the display module 51, and the light-shielding part can separate the multiple hollow display sections 54 from each other, so that the display module 51 is less likely to interfere with each other when emitting light through the multiple hollow display sections 54, which helps to improve the clarity of the information displayed by the display module 51.

[0113] like Figure 13As shown, in some embodiments, the housing 50 has an opening corresponding to the outer periphery of the cover 53 and communicating with the second receiving cavity 59. A wiring harness (e.g., the third connecting line 57 described later) can be connected to the display module 51 through the opening. The wiring harness provides current or control signals to the display module 51. After the display housing 5 is assembled, the wiring harness can be sealed with adhesive at the opening to reduce the possibility of external impurities entering the second receiving cavity 59, thereby improving the stability of the display module 51. It should be noted that the opening and the cable outlet 55 described later can be the same opening or different openings. For example, the opening and the cable outlet 55 can be different openings, and the cable outlet 55 can be formed on the housing 50 and spaced apart on the outer periphery of the cover 53.

[0114] like Figure 17 As shown, in some embodiments, the display box 5 is located on one side of the air outlet frame 4 in its width direction, and the display box 5 is located adjacent to the air outlet frame 4. The display box 5 and the air outlet frame 4 are fixed to the air outlet panel 3 by a common fastener, which helps to reduce the number of fasteners used, and at the same time makes the relative position of the display box 5 and the air outlet frame 4 more stable, which helps to improve the stability of the operation of the kitchen air conditioner indoor unit 100.

[0115] like Figure 13 and Figure 14 As shown, in some embodiments, the cutout display section 54 includes a cutout digital display section 54a. The cutout digital display section 54a is located at the middle of the cover 53 along the length of the air outlet frame 4, and the cutout digital display section 54a protrudes from the outer periphery of the cover 53. The cutout digital display section 54a protrudes from the outer edge of the side surface of the cover 53 facing the air outlet panel 3, so that the gap between the cutout digital display section 54a and the air outlet panel 3 in the vertical direction is smaller. This makes the cutout digital display section 54a and the air outlet panel 3 fit more tightly after the display box 5 and the air outlet panel 3 are assembled. The light emitted by the display module 51 can be displayed more clearly on the air outlet panel 3 through the cutout digital display section 54a, which is beneficial to improving the display effect of the display module 51.

[0116] like Figure 14 and Figure 15 As shown, in some embodiments, the protrusion height of the cutout digital display portion 54a relative to the edge of the surface of the cover 53 facing the air outlet panel 3 is h, 0.1mm≤h≤0.5mm.

[0117] As can be seen, by setting the protrusion height of the hollowed-out digital display part 54a relative to the edge of the surface of the cover 53 facing the air outlet panel 3 within 0.1mm to 0.5mm, the hollowed-out digital display part 54a can better fit the air outlet panel 3 under the fixing connection force between the display box 5 and the air outlet panel 3, reducing the assembly gap between the hollowed-out display part 54a and the air outlet panel 3, improving the display effect of the hollowed-out display part 54a, while the cover 53 does not occupy a large space in the vertical direction. For example, h can be 0.1mm, 0.16mm, 0.21mm, 0.25mm, 0.32mm, 0.38mm, 0.42mm, 0.48mm, 0.5mm, etc.

[0118] In some embodiments, the display box 5 has empty spaces at both ends along its length, which can be used to place a speaker and / or microphone. Combined with corresponding software control programs, this enables voice control of the kitchen air conditioner indoor unit 100, thus enriching the functionality of the kitchen air conditioner indoor unit 100. For example, along the length of the display box 5, the length of the box body 50 is greater than the length of the cover 53, and both ends of the box body 50 extend beyond the corresponding ends of the cover 53. The portion of the box body 50 extending beyond the cover 53 can be used to house a speaker and / or microphone.

[0119] like Figure 16 and Figure 17 As shown, in some embodiments, the display box 5 has a cable outlet 55 at one end of the air outlet frame 4 along its length. The kitchen air conditioner indoor unit 100 also includes: an electrical control box 60, a first air guide assembly 44, and a second air guide assembly 47. The electrical control box 60 is located on the side of the air supply component 2 away from the cable outlet 55 along the length of the display box 5. The first air guide assembly 44 is located on the air outlet frame 4 and includes a first air guide structure 45 and a first driver 46. The first driver 46 is located at or near one end of the air outlet frame 4 corresponding to the cable outlet 55 along its length, and the first driver 46 is used to drive the first air guide structure 45 to swing along the length of the display box 5. The first driver 46 has a first connecting line 46a, which passes through the display box 5. The first cable routing buckle 56 extends into the cable outlet 55; the second air guide assembly 47 is disposed on the air outlet frame 4 and includes a second air guide structure 48 and a second driver 49. The second driver 49 is disposed on or near one end of the air outlet frame 4 corresponding to the cable outlet 55 in its length direction, and the second driver 49 is used to drive the second air guide structure 48 to swing in the width direction of the air outlet frame 4. The second driver 49 has a second connecting line 49a, which extends into the cable outlet 55 via the first cable routing buckle 56 and the second cable routing buckle 32 on the air outlet panel 3. The display box 5 has a third connecting line 57, which extends out of the cable outlet 55 and extends toward the electronic control box 60 via the second cable routing buckle 32, the first cable routing buckle 56 and the third cable routing buckle 4c on the air outlet frame 4.

[0120] As can be seen, the outlet 55 is located at one end of the display box 5 in the length direction, and the first driver 46 is located at or near the end of the air outlet frame 4 corresponding to the outlet 55 in the length direction, so that the distance between the first driver 46 and the outlet 55 in the length direction of the air outlet frame 4 is shorter. The first connecting line 46a of the first driver 46 extends into the outlet 55 through the first wiring buckle 56. The above-mentioned arrangement of the first driver 46 and the outlet 55 makes the wiring path of the first connecting line 46a shorter, which is convenient for the wiring of the first connecting line 46a. At the same time, the wiring buckle 56 makes the wiring path of the first connecting line 46a clearer, so as to reduce the possibility that the first connecting line 46a and the display box 5 or the air outlet frame 4 will at least partially overlap in the horizontal direction, so that the first connecting line 46a is not easily broken during the assembly of the kitchen air conditioner indoor unit 100, which helps to improve the stability of the first connecting line 46a. For example, the first driver 46 is located on one side of the width of the air outlet frame 4 and adjacent to one end of the air outlet frame 4 in the length direction corresponding to the outlet 55. There are multiple first wiring clips 56, some of which are located at one end of the display box 5 in the length direction corresponding to the outlet 55, and other parts of which are located at one end of the display box 5 in the width direction corresponding to the first driver 46. This allows the wiring of the first connecting line 46a to be closer to the outer peripheral wall of the display box 5, making the wiring path of the first connecting line 46a more regular and clear, and reducing the possibility of the first connecting line 46a being crushed. Of course, there can also be only one first wiring clip 56.

[0121] The cable outlet 55 is located at one end of the display box 5 in the length direction. The second driver 49 is located at or near the end of the air outlet frame 4 corresponding to the cable outlet 55 in the length direction, so that the distance between the second driver 49 and the cable outlet 55 in the length direction is shorter. The second connecting wire 49a of the second driver 49 extends into the cable outlet 55 via the first cable routing buckle 56 and the second cable routing buckle 32. For example, the second connecting wire 49a first passes through the first cable routing buckle 56 and then through the second cable routing buckle 32 to extend into the cable outlet 55, or the second connecting wire 49a first passes through the second cable routing buckle 32 and then through the first cable routing buckle 56 to extend into the cable outlet 55. The cable outlet 55, along with the aforementioned second driver 49 and cable outlet 55, shortens the routing path of the second connecting cable 49a, facilitating its routing. Simultaneously, the first cable clip 56 and the second cable clip 32 further clarify the routing path of the second connecting cable 49a, reducing the likelihood of at least partial overlap between the second connecting cable 49a and the display box 5 or the air outlet frame 4 in the horizontal direction. This makes the second connecting cable 49a less prone to breakage during the assembly of the kitchen air conditioner indoor unit 100, improving its stability. For example, the second driver 49 is located at one end of the air outlet frame 4 corresponding to the cable outlet 55 in the length direction, and the second cable clip 32 is located at one end of the air outlet panel 3 corresponding to the cable outlet 55 in the length direction of the air outlet frame 4, with the second cable clip 32 adjacent to the air outlet frame 4. The second connecting cable 49a and the first connecting cable 46a share at least one first cable clip 56, allowing the first cable clip 56 to serve multiple purposes.

[0122] For example, there are multiple first wiring clips 56 on the display box 5, some of which are located at one end of the display box 5 in the length direction corresponding to the cable outlet 55, and other of which are located at one end of the display box 5 in the width direction corresponding to the first driver 46. The second wiring clip 32 is spaced apart on one side of the display box 5 in the width direction of the air outlet frame 4, and the second wiring clip 32 is opposite to the air outlet frame 4. The second connecting wire 49a can extend into the outlet 55 through the second wiring clip 32 and the first wiring clip 56 located at one end in the width direction of the display box 5; or the second connecting wire 49a can extend into the outlet 55 through the second wiring clip 32 and the first wiring clip 56 located at one end in the length direction of the display box 5; or the second connecting wire 49a can extend into the outlet 55 through the second wiring clip 32 and the first wiring clip 56 located at one end in the width direction of the display box 5, and the first wiring clip 56 located at one end in the length direction of the display box 5, so that the wiring path of the second connecting wire 49a is more regular and clear, and the possibility of the second connecting wire 49a being crushed is reduced.

[0123] The third connecting wire 57 of the display box 5 extends from the outlet 55, passes through the second wiring clip 32, the first wiring clip 56 and the third wiring clip 4c on the air outlet frame 4, and extends toward the electrical control box 60. This makes the wiring path of the third connecting wire 57 clearer, so as to reduce the possibility that the third connecting wire 57 and the display box 5 or the air outlet frame 4 will at least partially overlap in the horizontal direction. This makes the third connecting wire 57 less likely to be broken during the assembly of the kitchen air conditioner indoor unit 100, and improves the stability of the third connecting wire 57.

[0124] It is understood that the order in which the third connecting line 57 passes through the second wiring clip 32, the first wiring clip 56 and the third wiring clip 4c is not limited, as long as the third connecting line 57 can pass through the second wiring clip 32, the first wiring clip 56 and the third wiring clip 4c.

[0125] For example, the third wiring clip 4c is located on the side of the air outlet frame 4 away from the display box 5, so as to reduce the restriction of the third wiring clip 4c on the distance between the air outlet frame 4 and the display box 5 and reduce the risk of interference between the third wiring clip 4c and the display box 5; there are multiple third wiring clips 4c, and the multiple third wiring clips 4c are spaced apart along the length direction of the air outlet frame 4; of course, there can also be one third wiring clip 4c.

[0126] As can be seen, the first wiring clip 56, the second wiring clip 32, and the third wiring clip 4c make the wiring paths of the first connecting wire 46a, the second connecting wire 49a, and the third connecting wire 57 clearer, reducing the possibility of these wires being broken. This ensures that the first connecting wire 46a, the second connecting wire 49a, and the third connecting wire 57 can stably transmit current or electrical signals, thus improving the operational stability of the kitchen air conditioner indoor unit 100. Furthermore, the control box 60 can fully utilize the space on the side of the air supply component 2 away from the outlet 55 along the length of the display box 5, making the layout of the kitchen air conditioner indoor unit 100 more rational.

[0127] like Figure 16As shown, in some embodiments, the kitchen air conditioner indoor unit 100 includes: an indoor unit housing 70a, an indoor unit chassis 1, an electrical control box 60, an indoor heat exchanger 61, an air supply component 2, an air outlet frame 4, and an air outlet panel 3. The indoor unit housing 70a covers the indoor unit chassis 1 to define a receiving cavity. The electrical control box 60, the indoor heat exchanger 61, and the air supply component 2 are all located within the receiving cavity. The indoor heat exchanger 61 is U-shaped. The air supply component 2 includes two indoor fans 20, both of which are located within the U-shaped space. The electrical control box 60 is spaced apart on the outer periphery of the indoor heat exchanger 61. The air outlet panel 3 covers the lower side of the indoor unit chassis 1 and forms an air outlet 30. The air outlet frame 4 is located at the air outlet 30 and is sealed between the indoor unit chassis 1 and the air outlet panel 3. It can be seen that the structure of the above-mentioned kitchen air conditioner indoor unit 100 is relatively compact, facilitating the miniaturization design of the kitchen air conditioner indoor unit 100.

[0128] like Figures 17-19As shown, in some embodiments, the kitchen air conditioner indoor unit 100 further includes a first air guide structure 45, which includes louvers 45a and connecting rods 45d. Multiple louvers 45a are spaced apart along the length of the air outlet frame 4. Each louver 45a has a spaced-apart first pivot portion 45b and second pivot portion 45c. The first pivot portion 45b is detachably and rotatably connected to the first mounting portion 4a of the air outlet frame 4. Thus, the louvers 45a can be connected to the first mounting portion 4a of the air outlet frame 4 via the first pivot portion 45b. When the air outlet frame 4 rotates relative to the air outlet frame 4, the second pivot 45c is detachably and rotatably connected to the second mounting part 45e of the connecting rod 45d. Thus, the louvers 45a can rotate relative to the connecting rod 45d via the second pivot 45c. The connecting rod 45d can drive multiple louvers 45a to rotate, and the rotation of the louvers 45a is not affected by the connecting rod 45d and the air outlet frame 4. This also facilitates the disassembly and assembly of individual louvers 45a. Users can disassemble each louver 45a individually according to actual maintenance needs. For example, if one louver 45a is accidentally damaged, the user can remove it via the first pivot 45b and the second pivot 45c corresponding to the louver 45a for individual maintenance and replacement without disassembling the entire first air guide structure 45, thus improving the maintenance efficiency of the louvers 45a. And / or, the kitchen air conditioner indoor unit 100 also includes a second air guide structure 48, which includes an air guide plate 48a. The air guide plate 48a has multiple third pivots spaced apart along the length of the air outlet frame 4. Each of the third pivot parts 48b is detachably and rotatably connected to the third mounting part 4b of the air outlet frame 4. This allows the air guide plate 48a to rotate relative to the air outlet frame 4 via the third pivot parts 48b. The third pivot parts 48b facilitate easier assembly and disassembly of the air guide plate 48a. Users can separate the third pivot parts 48b of the air guide plate 48a from the third mounting part 4b of the air outlet frame 4, thus removing the air guide plate 48a from the air outlet frame 4 and improving maintenance efficiency. The air guide plate 48a has multiple spaced-apart third pivot parts 48b, each cooperating with a corresponding third mounting part 4b, to ensure a more stable fit between the air guide plate 48a and the air outlet frame 4, resulting in a more stable position for the air guide plate 48a and improved operational stability.

[0129] In related technologies, the louvers and air guide plate structures of kitchen air conditioners are made into a single component, with the louver installation structure hidden inside, making it difficult to disassemble and clean. Over extended use in kitchen environments, grease can accumulate on the air guide plate or individual louvers, requiring the entire component to be disassembled, cleaned, dried, lubricated, and then reassembled. Otherwise, the hidden installation structure may trap wastewater, leading to bacterial growth. Furthermore, forgetting to add lubricant before disassembly and reassembly is inconvenient and time-consuming. The aforementioned design in this application allows for the disassembly, replacement, and maintenance of individual louvers 45a and / or the disassembly, replacement, and maintenance of the air guide plate 48a, facilitating cleaning, drying, lubrication, and reinstallation.

[0130] In some embodiments, due to space constraints between the air outlet frame 4 and the indoor unit chassis 1, the multiple louvers 45a have different sizes to accommodate different installation situations. For example, taking two first connecting ports 10a as an example, the two first connecting ports 10a are spaced apart, and the vertical height of the louvers 45a opposite to each first connecting port 10a is greater than the vertical height of the louvers 45a spaced apart from the two first connecting ports 10a. Of course, when there is sufficient space between the air outlet frame 4 and the indoor unit chassis 1, the multiple louvers 45a can have the same size to improve the consistency of louver manufacturing and increase the production efficiency of louvers 45a.

[0131] like Figures 19-22 and Figure 29 As shown, in some embodiments, a bushing 68 is further provided between the third pivot portion 48b and the third mounting portion 4b. The bushing 68 is detachably connected to the third mounting portion 4b. When the air guide plate 48a drives the third pivot portion 48b to rotate, the bushing 68 will not rotate with the third pivot portion 48b. Therefore, relative rotation can occur between the third pivot portion 48b and the bushing 68, but relative rotation will not occur between the bushing 68 and the third mounting portion 4b. This allows the bushing 68 to reduce the wear of the third mounting portion 4b, thereby extending its service life. It is understood that when the bushing 68 experiences significant wear, the user can replace the bushing 68 to prevent further wear on the third mounting portion 4b and extend its service life.

[0132] like Figures 18-28 As shown, in some embodiments, the kitchen air conditioner indoor unit 100 includes a first air guide structure 45, and the kitchen air conditioner indoor unit 100 is configured to satisfy at least one of the following conditions A1 to A4:

[0133] In condition A1, the engagement of the first pivot 45b and the first mounting part 4a is exposed at the air outlet 30, allowing the user to see the engagement of the first pivot 45b and the first mounting part 4a through the air outlet 30. Similarly, the engagement of the second pivot 45c and the second mounting part 45e is exposed at the air outlet 30, allowing the user to see the engagement of the second pivot 45c and the second mounting part 45e through the air outlet 30. This makes the engagement of the louver 45a with the air outlet frame 4 and the connecting rod 45d more intuitive. Users can more clearly see the disassembly and assembly process of the louver 45a with the air outlet frame 4 and the connecting rod 45d, which improves the efficiency of disassembly and assembly of the louver 45a. This allows users to easily remove the louver 45a for maintenance or to add grease. At the same time, after the user assembles the louver 45a with the air outlet frame 4 and the connecting rod 45d through the air outlet 30, the user can also check in time whether the louver 45a has been missed with grease, which helps to improve the operational stability of the louver 45a.

[0134] In condition A2, at least one first pivot portion 45b is formed as a first pivot shaft 62, and a corresponding first mounting portion 4a is formed as a first pivot hole 63. The first pivot shaft 62 includes a first shaft body 62a, a limiting protrusion 62b, and a first limiting platform 62c. The limiting protrusion 62b and the first limiting platform 62c are both protruding from the outer peripheral wall of the first shaft body 62a and are spaced apart along the axial direction of the first shaft body 62a. The first pivot hole 63 includes a first main hole 63a and a first notch 63b. The first notch 63b is formed on the peripheral wall of the first main hole 63a. The limiting protrusion 62b is adapted to allow the first shaft body 62a to engage with the first main hole 63a through the first notch 63b. The limiting protrusion 62b limits the engagement with the side of the first main hole 63a away from the first limiting platform 62c. The limiting protrusion 62b is adapted to be offset from the first notch 63b in the circumferential direction of the first main hole 63a.

[0135] As can be seen, the limiting protrusion 62b can pass through the first notch 63b along the axial direction of the first pivot hole 63 to fit the first shaft 62a into the first main hole 63a, thereby completing the engagement of the first pivot part 45b and the first mounting part 4a. At this time, the limiting protrusion 62b is engaged with the side of the first main hole 63a away from the first limiting platform 62c. Then, the first pivot shaft 62 is rotated so that the limiting protrusion 62b and the first notch 63b are misaligned in the circumferential direction of the first main hole 63a, thereby limiting the engagement of the limiting protrusion 62b with the side of the first main hole 63a away from the first limiting platform 62c. At this time, the portion of the first main hole 63a is limited to the limiting position. Between the protrusion 62b and the first limiting platform 62c, both the limiting protrusion 62b and the first limiting platform 62c protrude from the outer peripheral wall of the first shaft 62a. Moreover, the limiting protrusion 62b is adapted to be offset from the first notch 63b in the circumferential direction of the first main hole 63a, so that the limiting protrusion 62b cannot disengage from the first main hole 63a through the first notch 63b. The limiting protrusion 62b and the first limiting platform 62c can limit the range of movement of the first shaft 62a in the first main hole 63a, so that the first shaft 62a and the first main hole 63a are not prone to separation, which facilitates the improvement of the stability of the cooperation between the first pivot part 45b and the first mounting part 4a.

[0136] It is understandable that after the louvers 45a and the air outlet frame 4 are installed, the limiting protrusion 62b and the first notch 63b are offset in the circumferential direction of the first main hole 63a. When the user controls the louvers 45a to swing, the swing amplitude of the louvers 45a is small, and the limiting protrusion 62b and the first notch 63b can always maintain the offset in the circumferential direction of the first main hole 63a. This makes it difficult for the limiting protrusion 62b to detach from the first main hole 63a through the first notch 63b, and the louvers 45a is not easy to separate from the air outlet frame 4. It can be seen that the first pivot part 45b and the first mounting part 4a are easy to assemble and disassemble and are simple to operate.

[0137] For example, when the louver 45a is in the normal use position, the included angle between the limiting protrusion 62b and the first notch 63b in the circumferential direction of the first main hole 63a is 90°. The user can first set the limiting protrusion 62b and the first notch 63b in parallel so that the limiting protrusion 62b fits into the side of the first main hole 63a away from the first limiting platform 62c through the first notch 63b. Then, the user can rotate the first shaft 62a to rotate the limiting protrusion 62b to a position where the included angle with the first notch 63b in the circumferential direction of the first main hole 63a is 90°. This makes it less likely for the first pivot part 45b and the first mounting part 4a to separate, and the louver 45a can maintain a stable working state.

[0138] For example, one of the first pivoting portions 45b is formed as a first pivot shaft 62. The first pivot shaft 62 can be connected to a drive motor (e.g., the first driver 46 mentioned above) by means of key connection or non-circular shaft hole engagement, and then drives multiple louvers 45a to rotate via connecting rod 45d to achieve control of the air outlet direction. It is understood that one first pivoting portion 45b can be formed as the first pivot shaft 62, or multiple first pivoting portions 45b can be formed as the first pivot shaft 62.

[0139] In condition A3, at least one first pivot portion 45b is formed as a second pivot hole 64, and a corresponding first mounting portion 4a is formed as a second pivot shaft 65. A second notch 64a is formed on the peripheral wall of the second pivot hole 64. The width of the second notch 64a is smaller than the diameter of the second pivot hole 64. The second pivot shaft 65 includes a second shaft body 65a and a second limiting platform 65b. The second limiting platform 65b protrudes from the outer peripheral wall of the second shaft body 65a. The second shaft body 65a is adapted to engage with the second pivot hole 64 through the second notch 64a. The second limiting platform 65b limits the engagement with the second pivot hole 64 on the side facing the center of the louver 45a.

[0140] As can be seen, the second shaft 65a is adapted to engage with the second pivot hole 64 through the second notch 64a, so that the second limiting platform 65b engages with the side of the second pivot hole 64 facing the center of the louver 45a. That is, the second limiting platform 65b is located between the center of the second pivot hole 64 and the center of the louver 45a. The width of the second notch 64a is smaller than the diameter of the second pivot hole 64, so that after the second shaft 65a engages with the second pivot hole 64, the second shaft 65a is not easy to disengage from the second pivot hole 64 through the second notch 64a, and the second limiting platform 65b can prevent the second shaft 65a from disengaging from the second pivot hole 64 along its axial direction, so that the first pivot part 45b and the first mounting part 4a are not easy to separate, so that the setting position of the louver 45a is more stable.

[0141] It is understandable that the width of the second notch 64a is smaller than the diameter of the second pivot hole 64. The user can apply a certain force to the second shaft 65a so that the second shaft 65a can be locked in the second pivot hole 64 through the second notch 64a. However, when the louver 45a is working normally, no force is applied to the second shaft 65a so that the second shaft 65a is not easy to disengage from the second pivot hole 64 through the second notch 64a, which helps to improve the stability of the fit between the first pivot part 45b and the first mounting part 4a.

[0142] For example, one of the plurality of first pivot portions 45b is connected to the first driver 46, the first pivot portion 45b being formed as a first pivot shaft 62, and the remaining first pivot portions 45b being formed as second pivot holes 64 to facilitate the engagement of the louver 45a with the first driver 46.

[0143] In condition A4, the second pivot part 45c is formed as the third pivot shaft 66, and the second mounting part 45e is formed as the third pivot hole 67. The third pivot shaft 66 includes a third shaft body 66a, a third limiting platform 66b, and a fourth limiting platform 66c. The third limiting platform 66b and the fourth limiting platform 66c are respectively protruding from the outer peripheral wall of the third shaft body 66a and are spaced apart along the axial direction of the third shaft body 66a. The third pivot hole 67 includes a second main hole 67a and a secondary hole 67b. The secondary holes 67b are respectively connected to both sides of the second main hole 67a in the length direction of the connecting rod 45d. The second limiting platform 65b and the third limiting platform 66b are fitted together at both ends of the axial direction of the second main hole 67a.

[0144] As can be seen, the third shaft 66a can be fitted into the second main hole 67a. At this time, the third limiting platform 66b and the fourth limiting platform 66c are respectively positioned at the two ends of the axial direction of the second main hole 67a. For example, the radial dimensions of the third limiting platform 66b and the fourth limiting platform 66c are larger than the radial dimensions of the second main hole 67a, so that the third shaft 66a and the second main hole 67a are less likely to separate, making the fit between the louver 45a and the connecting rod 45d more stable, and the louver 45a can maintain a stable working state.

[0145] In addition, the second main hole 67a is connected to the secondary holes 67b on both sides of the connecting rod 45d along its length. By providing secondary holes 67b on both sides of the second main hole 67a along its length, the structural strength of the peripheral wall of the second main hole 67a can be weakened. This allows the second main hole 67a to undergo a certain deformation when the third limiting platform 66b or the fourth limiting platform 66c is assembled or disassembled in the second main hole 67a. This makes it easier to assemble or disassemble the third limiting platform 66b or the fourth limiting platform 66c in the second main hole 67a, thus simplifying the assembly and disassembly process of the louver 45a and the connecting rod 45d.

[0146] For example, the secondary hole 67b can extend into a strip-shaped hole along the length of the connecting rod 45d to adapt to the structure of the connecting rod 45d and take into account the structural strength of the connecting rod 45d.

[0147] like Figures 24-28 As shown, in some embodiments, the fourth limiting platform 66c is located at the free end of the third pivot shaft 66, and the fourth limiting platform 66c is configured as a cone, with the small end of the cone facing away from the third limiting platform 66b. The cone-shaped fourth limiting platform 66c can play a guiding role, so as to make the assembly of the second pivot part 45c and the second mounting part 45e more convenient.

[0148] like Figure 18 , Figure 19 and Figure 22 As shown, in some embodiments, the kitchen air conditioner indoor unit 100 includes a second air guide structure 48, and the kitchen air conditioner indoor unit 100 is configured to satisfy at least one of the following conditions B1 to B2:

[0149] If there are three or more third pivot parts 48b in condition B1, then there are also three or more third mounting parts 4b. The third pivot parts 48b and the third mounting parts 4b are arranged in a one-to-one correspondence. By having multiple third pivot parts 48b and multiple third mounting parts 4b, it is easier to enhance the fit between the air guide plate 48a and the air outlet frame 4, so that the fit between the air guide plate 48a and the air outlet frame 4 is more stable, and the air guide plate 48a and the air outlet frame 4 are less likely to separate, so that the air guide plate 48a can have a stable working effect.

[0150] In condition B2, the mating of the third pivot 48b and the third mounting part 4b is exposed at the air outlet 30. This allows the user to see the third pivot 48b and the third mounting part 4b through the air outlet 30, making the mating of the air guide plate 48a and the air outlet frame 4 more intuitive. Users can also more easily observe the assembly and disassembly process of the air guide plate 48a and the air outlet frame 4, facilitating easy removal and maintenance or replacement of the air guide plate 48a, thus improving maintenance efficiency. Furthermore, if grease is added to the mating area between the third pivot 48b and the third mounting part 4b, after the user assembles the air guide plate 48a onto the air outlet frame 4 through the air outlet 30, the user can promptly check whether grease has been missed at the third pivot 48b.

[0151] like Figure 22As shown, in some embodiments, one of the third pivot portions 48b is connected to the second actuator 49 so that the second actuator 49 drives the air guide plate 48a to rotate. The third pivot portion 48b is formed as a non-circular pivot hole (e.g., polygonal, D-shaped). The second actuator 49 can directly or through a bushing engage with the third pivot portion 48b. Of course, the third pivot portion 48b and the second actuator 40 can also achieve circumferential limiting in other ways, such as key engagement, screw engagement, pin engagement, etc.

[0152] In some embodiments, the air outlet frame 4 and the air supply component 2 are separate components, and the air outlet frame 4 and the air outlet panel 3 are also separate components, so that the air outlet frame 4 and the air outlet panel 3 can be made in different colors to improve the aesthetics of the kitchen air conditioner indoor unit 100. In other embodiments of this application, the air outlet frame 4 and the air supply component 2 are separate components, and the air outlet frame 4 and the air outlet panel 3 are an integral piece, so that airflow is less likely to leak from the gap between the air outlet frame 4 and the air outlet panel 3, and at the same time, it is beneficial to improve the assembly efficiency of the air outlet frame 4 and the air outlet panel 3.

[0153] According to a second aspect of the present invention, a kitchen air conditioner 200 includes an indoor unit component 70 and an outdoor unit component 71, wherein the indoor unit component 70 is the kitchen air conditioner indoor unit 100 according to a first aspect of the present invention.

[0154] According to the embodiments of the present invention, the kitchen air conditioner 200, due to the good stability of the above-mentioned kitchen air conditioner indoor unit 100, facilitates the improvement of the stability of kitchen air conditioner operation.

[0155] like Figures 30-32 As shown, in some embodiments, the kitchen air conditioner 200 is an integrated air conditioner (e.g., the outdoor unit component 71 includes an outdoor unit chassis 81, which is integrally connected with the indoor unit chassis 1), and the air outlet panel 3 covers the lower side of the outdoor unit chassis 81. A clearance groove 72 for avoiding the joists is defined between the indoor unit component 70 and the outdoor unit component 71; and / or, the kitchen air conditioner 200 also includes a lighting structure 73, which is detachably installed on the side of the air outlet panel 3 facing away from the indoor unit chassis 1, and the lighting structure 73 is spaced apart from the air outlet 30.

[0156] For example, in a single-unit air conditioner, the indoor unit 70 includes an indoor housing 70a, the outdoor unit 71 includes an outdoor housing 71a, and a clearance groove 72 is located between the indoor housing 70a and the outdoor housing 71a. The clearance groove 72 can be configured as a straight groove. The indoor unit 70 and the outdoor unit 71 are located on opposite sides of the clearance groove 72, and the indoor unit 70 and the outdoor unit 71 are separated by the clearance groove 72.

[0157] The ceiling includes a keel as a supporting structure and spliced ​​decorative panels installed on the keel. There are multiple spliced ​​decorative panels connected to the keel. The multiple spliced ​​decorative panels are distributed in a matrix. Visually, the ceiling is a horizontally set flat plate. The keel includes multiple first keels. The multiple first keels are set in parallel and located on the same horizontal plane. There is a gap between two adjacent first keels. The distance between two adjacent first keels is the same.

[0158] In other designs, the keel also includes multiple second keels extending perpendicular to the first keel. Adjacent second keels are spaced apart, with equal spacing between them. The multiple first and second keels form a mesh structure, with each decorative panel covering one mesh opening. The shape of the decorative panels is not limited; they can be square or hexagonal, etc. The method of fixing the keel to the wall is not limited. In some designs, the keel is fixed to the wall at its ends. The kitchen ceiling has a hanging structure, and the keel is fixed to the hanging structure, thus suspending the entire ceiling.

[0159] In related technologies, when the kitchen air conditioner is installed before the ceiling, the air conditioner needs to be installed first and then the ceiling, or the ceiling can be partially installed first, the air conditioner can be hoisted, and then the remaining keel and splicing decorative panels can be installed. When the kitchen air conditioner is installed after the ceiling, due to the large size of the integrated kitchen air conditioner, it is usually necessary to remove some splicing decorative panels and keel for installation. When the kitchen air conditioner needs to be cleaned or maintained, at least some splicing decorative panels need to be removed. If disassembly and repair are required, the ceiling keel also needs to be removed. This makes the cleaning and maintenance of the kitchen air conditioner very time-consuming, labor-intensive, and cumbersome.

[0160] The kitchen air conditioner 200 of this application is equipped with a clearance channel 72, which allows either the first or second joist to pass through. During installation, the opening of the clearance channel 72 is aligned with the first joist below the ceiling. The air conditioner 200 is then raised to the desired height, allowing the first joist to enter the clearance channel 72 until it reaches the bottom. Finally, the air conditioner 200 is fixed in place, for example, by suspending it. The installation is complete without disassembling the existing joists. After installation, except for the air outlet panel 3, all other parts of the air conditioner 200 can be concealed within the space above the ceiling, resulting in a more aesthetically pleasing appearance. Correspondingly, when the kitchen air conditioner 200 needs to be repaired, it is only necessary to remove the fixing of the kitchen air conditioner 200 and vertically lower the height of the kitchen air conditioner 200 to disassemble it. During the disassembly of the kitchen air conditioner 200, it is not necessary to disassemble the installed keel, which can reduce the repair steps and time and improve the repair efficiency of the kitchen air conditioner 200.

[0161] like Figure 32 , Figure 33a and Figure 33b As shown, the kitchen air conditioner 200 also includes a lighting structure 73. The lighting structure 73 is detachably installed on the side of the air outlet panel 3 away from the indoor unit chassis 1, so that the lighting structure 73 does not easily affect the layout of the components inside the indoor unit 70. The lighting structure 73 is spaced apart from the air outlet 30. By adding the lighting structure 73 to the kitchen air conditioner 200, the functionality of the kitchen air conditioner 200 is enriched, and the kitchen air conditioner 200 does not reduce the lighting level of the external environment, so that the user can be in a relatively bright environment when using the kitchen air conditioner 200. The lighting structure 73 is spaced apart from the air outlet 30, so that the airflow blown from the air outlet 30 does not easily come into contact with the lighting structure 73, so that condensation does not easily form inside the lighting structure 73, which helps to improve the service life of the lighting structure 73. The lighting structure 73 is detachably connected to the air outlet panel 3. When the user does not need the lighting capability of the kitchen air conditioner 200, the lighting structure 73 can be removed; when the user needs the lighting capability of the kitchen air conditioner 200, the lighting structure 73 can be installed, which can meet the different usage needs of the user.

[0162] In some embodiments, the lighting structure 73 includes a circuit board and an LED light panel, with the LED light panel located on the side of the circuit board away from the indoor unit chassis 1, so that the light emitted by the LED light panel can more easily illuminate the room.

[0163] Optionally, the LED light panel includes ambient lighting. The color of the ambient lighting is controlled in conjunction with the operating status of the kitchen air conditioner 200. Blue represents cooling, yellow or warm colors represent heating, and the darker the color, the greater the cooling or heating capacity, thus making the air temperature visible and improving the user experience.

[0164] like Figure 33b As shown, in some embodiments, the lighting structure 73 and the air outlet panel 3 are fixed by magnetic attraction. For example, the air outlet panel 3 is provided with a magnetic component that can attract the lighting structure 73, making it difficult for the lighting structure 73 and the air outlet panel 3 to separate. The magnetic attraction also makes the installation and removal of the lighting structure 73 more convenient, improving the efficiency of replacing or maintaining the lighting structure 73. There can be one or more magnetic components, and the connection method between the magnetic component and the air outlet panel 3 is not limited. For example, the magnetic component can be detachably connected to the air outlet panel 3 via a claw 33.

[0165] like Figures 33a-38 As shown, in some embodiments, the kitchen air conditioner 200 further includes a lighting structure 73, which is vertically opposite to the outdoor unit component 71. The kitchen air conditioner 200 also includes a transparent decorative panel 74, which covers the lighting structure 73. The two opposite ends of the transparent decorative panel 74 have a fixing structure 74a and a mating structure 74b, respectively. The fixing structure 74a is detachably connected to the air outlet panel 3, and the mating structure 74b is detachably hung and mated with the air outlet panel 3.

[0166] As can be seen, the transparent decorative panel 74 is placed over the lighting structure 73. The transparent decorative panel 74 can provide a certain degree of protection for the lighting structure 73, so that external impurities are not easily exposed to the lighting structure 73, which helps to improve the stability of the lighting structure 73. At the same time, the transparent decorative panel 74 will not affect the normal operation of the lighting structure 73.

[0167] In addition, the transparent decorative panel 74 has a fixing structure 74a and a mating structure 74b at opposite ends. The fixing structure 74a is detachably connected to the air outlet panel 3, so as to make the assembly and disassembly of the transparent decorative panel 74 and the air outlet panel 3 more convenient, and to improve the efficiency of replacement or maintenance of the transparent decorative panel 74.

[0168] Among them, the mating structure 74b and the air outlet panel 3 can be detached and hung together. The mating structure 74b and the air outlet panel 3 can also be detached and hung together. When the two are together, they are hung together. After the fixing structure 74a of the transparent decorative panel 74 and the air outlet panel 3 are separated, the transparent decorative panel 74 can still be hung on the air outlet panel 3 through the mating structure 74b, so that the transparent decorative panel 74 will not fall directly, reducing the possibility of the transparent decorative panel 74 falling, which can improve the safety of the staff and reduce the number of staff required to disassemble and assemble the transparent decorative panel 74.

[0169] For example, when the transparent decorative panel 74 needs to be disassembled, the worker can first separate the fixing structure 74a of the transparent decorative panel 74 from the air outlet panel 3. At this time, the transparent decorative panel 74 can be hung on the air outlet panel 3 through the mating structure 74b. Then, the mating structure 74b of the transparent decorative panel 74 can be separated from the air outlet panel 3, thus completing the disassembly of the transparent decorative panel 74. When the transparent decorative panel 74 needs to be assembled, the worker can first assemble the mating structure 74b of the transparent decorative panel 74 with the air outlet panel 3. At this time, the transparent decorative panel 74 can be hung on the air outlet panel 3 through the mating structure 74b. Then, the fixing structure 74a of the transparent decorative panel 74 can be hung with the air outlet panel 3, thus completing the assembly of the transparent decorative panel 74. Therefore, the worker can first disassemble or assemble one side of the fixing structure 74a or the mating structure 74b of the transparent decorative panel 74. The transparent decorative panel 74 is not likely to fall off, which can reduce the number of workers required to disassemble and assemble the transparent decorative panel 74, and facilitate the reduction of the maintenance cost of the transparent decorative panel 74.

[0170] It is understandable that the detachable connection method of the transparent decorative panel 74 and the air outlet panel 3 is not limited, including at least one of the following: threaded connection, snap-on connection, magnetic engagement, etc., and users can choose according to the actual installation situation.

[0171] like Figures 35-38 As shown, in some embodiments, the mating structure 74b is configured to rotate and engage with the air outlet panel 3. The mating structure 74b is then attached to the air outlet panel 3, and through this engagement, the transparent decorative panel 74 can rotate relative to the air outlet panel 3. This allows the transparent decorative panel 74 to rotate downwards around the position of the mating structure 74b after the fixing structure 74a and the air outlet panel 3 are separated. As long as the mating structure 74b is not separated from the air outlet panel 3, the transparent decorative panel 74 will not fall off. After the transparent decorative panel 74 rotates downwards, its height is relatively lower, making it easier for workers to hold the transparent decorative panel 74 and separate the mating structure 74b from the air outlet panel 3.

[0172] For example, the air outlet panel 3 has a mating hole 34 and a hanging portion 35. The hanging portion 35 is located on the side edge of the mating hole 34 away from the fixing structure 74a and extends upward. The mating structure 74b is adapted to be hung on the side of the hanging portion 35 away from the mating hole 34 through the mating hole 34. The mating structure 74b includes a first mating portion 741, a second mating portion 742, a third mating portion 743, and a fourth mating portion 744. The first mating portion 741 extends from the end edge of the transparent decorative panel 74 away from the fixing structure 74a along the thickness direction of the transparent decorative panel 74. The second mating portion 742 extends from one end of the first mating portion 741 toward a direction away from the fixed structure 74a, and the third mating portion 743 extends from the end of the second mating portion 742 away from the first mating portion 741 along the thickness direction of the transparent decorative panel 74, so that the first mating portion 741 and the third mating portion 743 are opposite to each other. The fourth mating portion 744 extends from the end of the third mating portion 743 away from the second mating portion 742 toward the first mating portion 741, and the end of the fourth mating portion 744 away from the third mating portion 743 is spaced apart from the first mating portion 741.

[0173] As can be seen, the mating structure 74b can have a first mating state and a second mating state. In the first and second mating states, the placement posture or angle of the transparent decorative panel 74 is different. In the first mating state, the fixing structure 74a is connected to the air outlet panel 3, the transparent decorative panel 74 is arranged horizontally, the mating structure 74b is supported on the upper side of the air outlet panel 3, and the hanging part 35 is mated between the first mating part 741 and the fourth mating part 744. In the second mating state, the fixing structure 74a is separated from the air outlet panel 3, and the transparent decorative panel 74 rotates downward at one end corresponding to the fixing structure 74a so that the transparent decorative panel 74 is tilted or vertical relative to the horizontal plane. At this time, the hanging part 35 is mated between the second mating part 742 and the fourth mating part 744. The transparent decorative panel 74 can be hung by the force between the hanging part 35 and the fourth mating part 744. The hanging part 35 and the mating structure 74b can be separated by moving the transparent decorative panel 74 upward relative to the air outlet panel 2 and moving the transparent decorative panel 74 away from the hanging part 35.

[0174] like Figures 35-38 As shown, in some embodiments, the side of the transparent decorative panel 74 away from the fixed structure 74a also has a snap-fit ​​structure 74c, and the air outlet panel 3 has a through opening 38. The snap-fit ​​structure 74c is snapped onto the upper side of the air outlet panel 3 through the corresponding opening 38 to limit the transparent decorative panel 74 and the air outlet panel 3 in the vertical direction. At the same time, the snap-fit ​​structure 74c is adapted to the opposite sidewall of the opening 38 to facilitate the limiting of the transparent decorative panel 74 and the air outlet panel 3 in the horizontal direction perpendicular to the arrangement direction of the fixed structure 74a and the mating structure 74b.

[0175] In some embodiments, the air outlet panel 3 has a mating hole 34, the transparent decorative panel 74 has a mating structure 74b, and the air outlet panel 3 further includes a first reinforcing structure 36 disposed adjacent to the mating hole 34; and / or, the air outlet panel 3 has an opening 38, the transparent decorative panel 74 has a snap-fit ​​structure 74c, and the air outlet panel 3 further includes a second reinforcing structure 37 disposed adjacent to the opening 38.

[0176] As can be seen, the first reinforcing structure 36 is disposed adjacent to the mating hole 34. The first reinforcing structure 36 can enhance the structural strength and stability of the mating hole 34, which is conducive to further improving the installation reliability of the mating hole 34 and the mating structure 74b. Moreover, when the mating hole 34 and the mating structure 74b need to be frequently disassembled and assembled, the mating hole 34 is not prone to large deformation during the disassembly and assembly process, so that the structure of the mating hole 34 is more stable, which facilitates improving the reliability of the kitchen air conditioner 200; and / or, the second reinforcing structure 37 is disposed adjacent to the opening 38. The second reinforcing structure 37 can enhance the structural strength and structural stability of the opening 38, which is conducive to further improving the installation reliability of the opening 38 and the snap-fit ​​structure 74c. Moreover, when the opening 38 and the snap-fit ​​structure 74c need to be frequently disassembled and assembled, the opening 38 is not prone to large deformation during the disassembly and assembly process, so that the structure of the opening 38 is more stable, which facilitates improving the reliability of the kitchen air conditioner 200.

[0177] It can be understood that the first reinforcing structure 36 may refer to the local thickening of the edge portion of the mating hole 34, or the first reinforcing structure 36 may refer to the provision of reinforcing ribs on the edge portion of the mating hole 34; the second reinforcing structure 37 may refer to the local thickening of the edge portion of the opening 38, or the second reinforcing structure 37 may refer to the provision of reinforcing ribs on the edge portion of the opening 38.

[0178] like Figure 39 and Figure 40As shown, in some embodiments, the outdoor unit component 71 includes an outdoor unit heat exchanger 80, an outdoor unit chassis 81, a water pumping device 82, a first pipeline water inlet 83, and a first refrigerant pipeline 84. The indoor unit component 70 includes an indoor unit heat exchanger, and the first refrigerant pipeline 84 is connected to one end of the indoor unit heat exchanger. The outdoor unit chassis 81 is located below the outdoor unit heat exchanger 80 and has a water inlet trough 81a and a water pumping trough 81b that are connected in communication. The outdoor unit heat exchanger 80 is located adjacent to the water pumping trough 81b. The water pumping device 82 includes a water pumping component 82a and a water pumping motor 82b. The water pumping component 82a is located in the water pumping trough 81b, and the water pumping motor 82b is connected to the water pumping component 82a. 2a are connected to drive the water pumping component 82a to pump the water in the water pumping tank 81b to the outdoor unit heat exchanger 80. The first pipe water receiving component 83 is located on the first refrigerant pipe 84 or on the outdoor unit chassis 81. The first pipe water receiving component 83 is located on the upper side of the water pumping motor 82b and has a first water receiving cavity 83a with a top opening. The first water receiving cavity 83a is used to receive condensate dripping from the first refrigerant pipe 84 toward the water pumping motor 82b. The first pipe water receiving component 83 has a first drain outlet 83b that communicates with the first water receiving cavity 83a. The first drain outlet 83b is opposite to and communicates with the water receiving tank 81a.

[0179] It is evident that during the operation of the kitchen air conditioner 200, condensation will occur on the outer surface of the first refrigerant pipe 84. At least a portion of the first refrigerant pipe 84 is located above the water pump motor 82b. There is a risk that the condensation generated by the first refrigerant pipe 84 will flow towards the water pump motor 82b. The first pipe water inlet 83 can collect the condensation dripping from the first refrigerant pipe 84 towards the water pump motor 82b, preventing the condensation from directly contacting the water pump motor 82b. This reduces the risk of the water pump motor 82b failing due to water immersion, improves the stability of the water pump motor 82b's operation, and, due to the aforementioned first pipe water inlet 83, reduces the requirements for the installation position of the water pump motor 82b. In related technologies, to reduce condensation... The impact of water on the pump motor is usually addressed by staggering the first refrigerant line and the pump motor to prevent condensate from dripping onto the pump motor. However, this significantly restricts the placement of the pump motor, limiting the internal layout of the air conditioner and hindering the miniaturization of the kitchen air conditioner. In the air conditioner according to the embodiment of this application, the first pipe water inlet 83 is placed on top of the pump motor 82b, allowing the condensate from the first refrigerant line 84 to be effectively collected by the first pipe water inlet 83. This reduces the restrictions on the placement of the pump motor 82b, enabling a more compact layout of the air conditioner and facilitating the miniaturization of the kitchen air conditioner 200.

[0180] For example, due to the limitations of the pipe routing, and in order to collect the condensate generated by the first refrigerant pipe 84, the first refrigerant pipe 84 is bent so that the lowest point on the first refrigerant pipe 84 is directly above the water pump motor 82b (as shown in Figure 39). The condensate can flow along the first refrigerant pipe 84 to the water pump motor 82b. At this time, the first pipe water inlet 83 can be set on the outdoor unit chassis 81. In the vertical direction of the kitchen air conditioner 200, the first pipe water inlet 83 is located between the water pump motor 82b and the first refrigerant pipe 84. The first water inlet cavity 83a can receive the condensate dripping from the first refrigerant pipe 84 toward the water pump motor 82b. Of course, the arrangement of the first refrigerant pipe and the first pipe water inlet 83 is not limited to this. For example, the first pipe water inlet 83 can also be located on the first refrigerant pipe 84. The first refrigerant pipe 84 passes through the first pipe water inlet 83 in the vertical direction, and the first water inlet cavity 83a is arranged around the first refrigerant pipe 84. In this way, the first water inlet cavity 83a can also receive the condensate generated by the first refrigerant pipe 84.

[0181] It is understood that the first refrigerant pipe 84 can be used to transfer the refrigerant when the indoor heat exchanger (such as the indoor heat exchanger 61 mentioned above) is working. For example, the first refrigerant pipe 84 is connected to the evaporator. Since the temperature difference between the first refrigerant pipe 84 and the outside environment is large when it is working, condensation is easily generated on the surface of the first refrigerant pipe 84. This application provides a first pipe water receiving part 83 to cover the upper side of the water pump motor 82b. The first pipe water receiving part 83 can receive the condensation generated by the first refrigerant pipe 84, so as to reduce the impact of condensation on the water pump motor 82b, thereby improving the stability of the operation of the kitchen air conditioner 200.

[0182] In addition, the water pumping component 82a is located in the water pumping tank 81b. The water pumping motor 82b can drive the water pumping component 82a to pump the water in the water pumping tank 81b onto the outdoor unit heat exchanger 80. For example, the water pumping component 82a pumps the water onto the condenser. As a heat exchange device, the condenser usually has a high surface temperature. By pumping the water onto the condenser, the water can cover at least part of the condenser. By utilizing the heat absorption effect of water evaporation, the heat transfer from the condenser to the environment is accelerated, and the heat dissipation efficiency of the condenser is improved, so as to improve the working efficiency of the kitchen air conditioner 200.

[0183] The first water inlet 83 has a first drain outlet 83b that connects to the first water inlet cavity 83a. The first drain outlet 83b is positioned opposite to the water inlet 81a and is connected to the water inlet 81a. For example, the first drain outlet 83b may be located above the water inlet 81a or extend downward toward the water inlet 81a, so that the water in the first water inlet cavity 83a can flow smoothly into the water inlet 81a. This prevents condensate from accumulating in the first water inlet cavity 83a, reducing the risk of condensate overflow and preventing condensate from contacting the water pump motor 82b or... The components of the first water inlet fitting 83 are designed to improve the safety of the water pump motor 82b or components near the first water inlet fitting 83, thereby improving the operational stability of the kitchen air conditioner 200. The water inlet trough 81a is connected to the water pump trough 81b, so the condensate in the first water inlet cavity 83a can flow through the water inlet trough 81a to the water pump trough 81b, and then the water pump fitting 82a agitates the condensate in the water pump trough 81b onto the condenser. The condenser can evaporate the condensate, so the condensate can pass through the first water inlet cavity 83a, the water inlet trough 81a, the water pump trough 81b and the condenser in sequence, so that the condensate can be effectively treated.

[0184] In some embodiments, the outdoor unit chassis 81 is provided with fasteners that pass through the first water pipe inlet 83 and the water pump motor 82b to fix both the first water pipe inlet 83 and the water pump motor 82b to the outdoor unit chassis 81.

[0185] As can be seen, the fasteners can simultaneously fix the first water inlet 83 and the water pump motor 82b to the outdoor unit chassis 81, making their positions more stable. Even if the kitchen air conditioner 200 is subjected to external force, the water pump motor 82b and the first water inlet 83 are not prone to relative movement. The first water inlet 83 can always protect the water pump motor 82b, which helps to improve the working stability of the water pump motor 82b. At the same time, the first water inlet 83 and the outdoor unit chassis 81 are not prone to relative movement, so that the condensate discharged from the first drain outlet 83b can be stably received by the water receiving tank 81a, which helps to improve the working stability of the kitchen air conditioner 200.

[0186] Furthermore, since the first water inlet fitting 83 and the water pump motor 82b share the same fasteners, it is not necessary to fix the first water inlet fitting 83 and the water pump motor 82b to the outdoor unit chassis 81 separately, thus reducing the number of fasteners used and facilitating assembly by the staff. It can be understood that the number of fasteners shared by the first water inlet fitting 83 and the water pump motor 82b can be one or more.

[0187] In some embodiments, a plurality of spaced-apart protrusions 83c are provided on the bottom wall of the first water receiving cavity 83a. When condensate from the first refrigerant pipe 84 drips onto the bottom wall of the first water receiving cavity 83a, the spaced-apart protrusions 83c can buffer and disperse the dripping condensate. For example, when condensate drips onto the bottom wall of the first water receiving cavity 83a, the splashing condensate will be blocked by the protrusions 83c, so that the condensate is less likely to splash outside the first water receiving cavity 83a, so that the condensate is less likely to come into contact with the water pump motor 82b, which is beneficial to improving the working stability of the water pump motor 82b.

[0188] It is understandable that the height of the protruding dot structure 83c is less than the height of the peripheral wall of the first water receiving cavity 83a, so that the protruding dot structure 83c is less likely to interfere with other components of the kitchen air conditioner 200 (such as the first refrigerant pipe 84), and the protruding dot structure 83c is less likely to affect the layout of the components inside the kitchen air conditioner 200, so that the structure of the air conditioner can be more compact. The structural form of the protruding dot structure 83c is not specifically limited; for example, the protruding dot structure 83c can be hemispherical or columnar, etc.

[0189] For example, a plurality of spaced protrusion structures 83c are provided on the bottom wall of the first water receiving cavity 83a. The plurality of protrusion structures 83c can be arranged in multiple rows and columns on the bottom wall of the first water receiving cavity 83a, or the plurality of protrusion structures 83c can be arranged in staggered rows on the bottom wall of the first water receiving cavity 83a, so as to make better use of the space inside the first water receiving cavity 83a.

[0190] like Figure 39 and Figure 40 As shown, in some embodiments, the kitchen air conditioner 200 also includes a water level switch 89. The water level switch 89 is disposed on the outdoor unit chassis 81 and is set corresponding to the water receiving tank 81a. The water level switch 89 can detect the water level in the water receiving tank 81a. The first pipeline water receiving component 83 has a support portion 83d, which protrudes from the outer periphery of the first water receiving cavity 83a and supports the water level switch 89 upward. The positions where the water level switch 89 mates with the outdoor unit chassis 81 and the positions where the water level switch 89 mates with the support portion 83d are spaced apart.

[0191] As can be seen, the support part 83d protrudes from the outer periphery of the first water receiving cavity 83a, so that the support part 83d does not easily affect the first water receiving cavity 83a from receiving condensate. At the same time, the support part 83d can better contact the water level switch 89, reducing the requirements for the installation position of the water level switch 89. The support part 83d supports the water level switch 89 upward. For example, the support part 83d supports the lower end of the water level switch 89, and the support part 83d can provide an upward support force to the water level switch 89. At the same time, combined with the cooperation between the water level switch 89 and the outdoor unit chassis 81, the water level switch 89 has at least two mating positions with other components. 9. The water level switch 89 is less prone to sagging; the positions where the water level switch 89 mates with the outdoor unit chassis 81 and with the support part 83d are spaced apart, so that the mate between the water level switch 89 and the outdoor unit chassis 81 is less affected by the support part 83d. At the same time, the above arrangement can increase the support range of the outdoor unit chassis 81 and the support part 83d for the water level switch 89. With the support part 83d and the outdoor unit chassis 81 jointly supporting the water level switch 89, the possibility of the water level switch 89 sagging is further reduced, so that the water level switch 89 can maintain a relatively stable working state, which is conducive to improving the stability of the operation of the kitchen air conditioner 200.

[0192] The water level switch 89 is located on the outdoor unit chassis 81 and is positioned corresponding to the water inlet 81a. This allows the water level switch 89 to be closer to the first pipeline water inlet 83, and the support part 83d to make better contact with the water level switch 89. The size of the support part 83d does not need to be too large, which helps to reduce the manufacturing cost of the first pipeline water inlet 83.

[0193] For example, the water level switch 89 is a dual water level switch. The dual water level switch is relatively large. If the water level switch 89 only cooperates with the outdoor unit chassis 81 (for example, the water level switch 89 is cooperated with the outdoor unit chassis 81 through a snap-fit ​​structure), the part of the water level switch 89 far from the cooperation position between the water level switch 89 and the outdoor unit chassis 81 is prone to sagging, so that the water level switch 89 cannot accurately reflect the water level in the water tank 81a. However, this application supports the water level switch 89 together with the support part 83d and the outdoor unit chassis 81. Even if the water level switch 89 is large, the water level switch 89 can be well supported, reducing the risk of sagging and improving the operational stability of the kitchen air conditioner 200.

[0194] like Figure 39 and Figure 40As shown, in some embodiments, the water level switch 89 includes an integrated first water level switch and a second water level switch. The water level at which the first water level switch operates is lower than the water level at which the second water level switch operates, and therefore the trigger water level of the first water level switch is lower than the trigger water level of the second water level switch. For example, when a large amount of water accumulates in the receiving tank 81a, the first water level switch is triggered first. The water level switch 89 transmits a signal to the controller of the kitchen air conditioner 200, reducing the operating power of the compressor 88 of the kitchen air conditioner 200, thereby reducing the condensate water generated on the first refrigerant pipe 84. Simultaneously, the condensate water in the receiving tank 81a can also be transferred to the drain tank 81b, which can consume some of the condensate water, thus lowering the water level in the receiving tank 81a, causing the first water level switch to deactivate. Afterward, the compressor 88 of the kitchen air conditioner 200 can operate at normal power. If, after lowering the operating power of the compressor 88, the water level in the receiving tank 81a continues to rise, meaning the amount of condensate water collected in the receiving tank 81a is greater than the amount collected in the drain tank 81b... The amount of condensate consumed in the water tank 81b continues until the second water level switch is triggered. At this point, the condensate in the water tank 81a may overflow. The water level switch 89 transmits a signal to the controller of the kitchen air conditioner 200, at which point the kitchen air conditioner 200 can be shut down. No excessive condensate will be generated on the first refrigerant line 84. Simultaneously, the condensate in the water tank 81a can be drained from the air conditioner through the drain outlet, lowering the water level in the water tank 81a and deactivating the second water level switch. The first water level switch remains activated. The kitchen air conditioner 200 can then operate at a lower power to further lower the water level in the water tank 81a until the first water level switch is deactivated. Afterward, the kitchen air conditioner 200 can operate normally. Therefore, by setting the first and second water level switches, the risk of condensate overflow in the water tank 81a is reduced, thereby reducing the risk of water immersion and failure of components within the kitchen air conditioner 200, thus improving the operational stability of the kitchen air conditioner 200.

[0195] The first and second water level switches are arranged sequentially along a first horizontal direction. One end of the water level switch 89 in the first horizontal direction mates with the outdoor unit chassis 81, and the other end of the water level switch 89 abuts against the support part 83d, for example, the support part 83d abuts against the lower end of the water level switch. By arranging the first and second water level switches sequentially along the first horizontal direction, the water level switch 89 is made larger in the first horizontal direction. The outdoor unit chassis 81 and the support part 83d support the water level switch 89 at both ends in the first horizontal direction, respectively. Both the outdoor unit chassis 81 and the support part 83d can provide upward support to the water level switch 89, making it less prone to sagging and improving the stability of the water level switch 89's operation. It can be understood that the first horizontal direction is perpendicular to the vertical direction, and the first horizontal direction can be a front-back direction, a left-right direction, or a horizontal direction that is inclined relative to both the front-back and left-right directions.

[0196] like Figures 39-42 As shown, in some embodiments, the outdoor unit component further includes a second refrigerant line 85 and a third refrigerant line 86. The second refrigerant line 85 is connected between the throttling device 87 of the kitchen air conditioner 200 and one end of the indoor unit heat exchanger. For example, both the first refrigerant line 84 and the second refrigerant line 85 are used to transfer refrigerant. The refrigerant passing through the throttling device 87 can first pass through the first refrigerant line 84 and then through the second refrigerant line 85 to reach the evaporator (e.g., Figure 39 As shown, refrigerant via the throttling device 87 can first pass through the second refrigerant line 85 and then through the first refrigerant line 84 to the evaporator, thus completing the refrigerant transfer between the throttling device 87 and the evaporator. The third refrigerant line 86 is connected to the other end of the evaporator; for example, one end of the third refrigerant line 86 is connected to the evaporator, and the other end is connected to the compressor 88, thus completing the refrigerant transfer between the evaporator and the compressor 88. It can be understood that the first refrigerant line 84 and the second refrigerant line 85 can correspond to the inlet end of the evaporator, and the third refrigerant line 86 corresponds to the outlet end of the evaporator. When the kitchen air conditioner 200 is running, condensate will be generated in the first refrigerant line 84, the second refrigerant line 85, and the third refrigerant line 86.

[0197] like Figures 39-42As shown, the kitchen air conditioner 200 further includes: a second pipe water inlet 90, which has a second water inlet cavity 91 with a top opening and a second drain outlet 92 communicating with the second water inlet cavity 91. The second drain outlet 92 is connected to a water inlet 81a. The bottom wall of the second water inlet cavity 91 has a first through hole 93 for one of the second refrigerant pipe 85 and the third refrigerant pipe 86 to pass through. For example, the second pipe water inlet 90 is used to collect condensate on the second refrigerant pipe 85, and the second refrigerant pipe 85 can pass through the first through hole 93; or the second pipe water inlet 90 is used to collect condensate on the third refrigerant pipe 86, and the third refrigerant pipe 86 can pass through the first through hole 93. A perforation 93; and / or a third pipe water inlet 94, the third pipe water inlet 94 having a third water inlet cavity 95 with a top opening and a third drain outlet 96 communicating with the third water inlet cavity 95, the third drain outlet 96 communicating with the water inlet 81a, the bottom wall of the third water inlet cavity 95 forming a second perforation 97 for another of the second refrigerant pipes 85 and the third refrigerant pipe 86 to pass through, for example, the third pipe water inlet 94 is used to collect condensate on the second refrigerant pipe 85, the second refrigerant pipe 85 can pass through the second perforation 97, or the third pipe water inlet 94 is used to collect condensate on the third refrigerant pipe 86, the third refrigerant pipe 86 can pass through the second perforation 97.

[0198] It is understood that when the kitchen air conditioner 200 includes a second pipe connection 90 and a third pipe connection 94, the second refrigerant pipe 85 passes through the first perforation 93 into the second pipe connection 90, and the third refrigerant pipe 86 passes through the second perforation 97 into the third pipe connection 94; or the third refrigerant pipe 86 passes through the first perforation 93 into the second pipe connection 90, and the second refrigerant pipe 85 passes through the second perforation 97 into the third pipe connection 94. Therefore, the condensate on the second refrigerant pipe 85 and the third refrigerant pipe 86 can be effectively collected by the second pipe connection 90 and the third pipe connection 94 respectively, preventing the condensate from dripping onto other components of the kitchen air conditioner 200 and improving the operational stability of the kitchen air conditioner 200.

[0199] like Figures 39-42As shown in Figure 1, in some embodiments, the kitchen air conditioner 200 includes a second water inlet 90 and a third water inlet 94. The second water inlet 90 and the third water inlet 94 are arranged sequentially in a horizontal direction, such that the second drain outlet 92 and the third drain outlet 96 are respectively opposite to and connected to the water inlet 81a. Therefore, condensate in the third water inlet cavity 95 will not flow to the second water inlet cavity 91 through the third drain outlet 96, and condensate in the second water inlet cavity 91 will not flow to the third water inlet cavity 95 through the second drain outlet 92. For example, the second drain outlet 92 and the third drain outlet 96 are both located above the water receiving tank 81a, or the first drain outlet 83b and the third drain outlet 96 both extend downward into the water receiving tank 81a. That is, the condensate in the second water receiving chamber 91 can flow directly to the water receiving tank 81a through the second drain outlet 92, and the condensate in the third water receiving chamber 95 can flow directly to the water receiving tank 81a through the third drain outlet 96. This makes it less likely for the second pipe water receiving fitting 90 and the third pipe water receiving fitting 94 to interfere with each other, and facilitates the improvement of the stability of the kitchen air conditioner 200 operation.

[0200] Of course, a portion of the second pipe water receiving component 90 can also be vertically opposite to the third pipe water receiving component 94. If the second pipe water receiving component 90 is located above the third pipe water receiving component 94, the second drain outlet 92 and the third water receiving cavity 95 are horizontally misaligned, so that the second drain outlet 92 and the third drain outlet 96 are respectively opposite to and connected to the water receiving trough 81a. Conversely, if the third pipe water receiving component 94 is located above the second pipe water receiving component 90, the third drain outlet 96 and the second water receiving cavity 91 are horizontally misaligned, so that the second drain outlet 92 and the third drain outlet 96 are respectively opposite to and connected to the water receiving trough 81a.

[0201] For example, the second water inlet 90 and the third water inlet 94 are spaced apart in the horizontal direction, so that the second water inlet cavity 91 and the third water inlet cavity 95 are spaced apart, and the second drain outlet 92 and the third drain outlet 96 are also spaced apart. The second water inlet 90 and the third water inlet 94 are less likely to interfere with each other, and the second water inlet 90 and the third water inlet 94 are less likely to interfere during assembly, which helps to improve the stability of the operation of the kitchen air conditioner 200.

[0202] In other embodiments of this application, the second water inlet 90 and the third water inlet 94 are arranged vertically in sequence, such that the second drain outlet 92 is connected to the water inlet 81a through the third water inlet cavity 95, or the third drain outlet 96 is connected to the water inlet 81a through the second water inlet cavity 91. For example, the second water inlet 90 is located above the third water inlet 94, and the condensate in the second water inlet cavity 91 can flow through the second drain outlet 92 to the third water inlet cavity 95, and then through the third drain outlet 96 to the water inlet 81a; or, the third water inlet 94 is located above the second water inlet 90, and the condensate in the third water inlet cavity 95 can flow through the third drain outlet 96 to the second water inlet cavity 91, and then through the second drain outlet 92 to the water inlet 81a. Therefore, the relative positions of the second water inlet 90 and the third water inlet 94 in the vertical direction are not limited, so that the arrangement of the second water inlet 90 and the third water inlet 94 is more flexible.

[0203] As can be seen, the second water connection fitting 90 and the third water connection fitting 94 can be arranged sequentially in the horizontal direction or in the vertical direction, so that the installation positions of the second water connection fitting 90 and the third water connection fitting 94 are more flexible, which makes it easier to adapt to different installation environments and improves the practicality of the second water connection fitting 90 and the third water connection fitting 94.
