Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a kitchen air conditioning device. Background Technology

[0002] The kitchen is the hottest and most smoky area in the home, especially during cooking, where high temperatures and fumes can severely impact user comfort. Therefore, installing dedicated air conditioning units in the kitchen has become an urgent need to improve the quality of modern home life. Unlike air conditioners used in ordinary rooms, kitchen air conditioners, in addition to needing strong cooling capacity, usually need to be embedded in cabinets or integrated into the system. Therefore, their dimensions, especially thickness and volume, have very stringent requirements.

[0003] To achieve a compact structure, existing kitchen air conditioners or similar small air conditioning units typically have an internal layout simply divided into two main functional areas: an evaporator side for absorbing indoor heat and blowing out cool air, and a condenser side for dissipating heat to the outside. This two-chamber layout separates the cold and hot sides with a partition to prevent crosstalk between hot and cold air and ensure basic cooling functionality.

[0004] However, in this common two-chamber design, the compressor is usually placed in the condenser side chamber, sharing the same space with heat dissipation components such as the condenser and condenser fan. To insulate and reduce noise from the compressor, additional insulation materials such as sound insulation cotton, heat insulation boards, or partitions are often required. These additional insulation materials occupy the already limited internal space within the casing, directly increasing the complexity of the structure and the overall physical size of the machine, making it difficult to reduce the size or make it thinner.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] In response to the problems pointed out in the background art, this application provides a kitchen air conditioning device that, through the integrated structural design of the water tray, not only serves the basic function of receiving condensate water, but also functions as a separator of the internal cavity, thereby simplifying the internal structure and enabling the overall layout to be highly compact.

[0007] To achieve the above-mentioned objectives, the present invention employs the following technical solution: This application provides a kitchen air conditioning device, including: a housing; a refrigeration system disposed within the housing, comprising a compressor, a condenser, a throttling device, and an evaporator connected in sequence by refrigeration pipes; a condenser fan for driving airflow through the condenser; and an evaporator fan for driving airflow through the evaporator to form a cooling airflow; the interior of the housing is divided into a compressor cavity for accommodating the compressor, an evaporator-side cavity for accommodating the evaporator and the evaporator fan, and a condenser-side cavity for accommodating the condenser and the condenser fan; the housing... The housing includes: a first partition plate, one end of which is connected to the end of the evaporator and the other end to the housing, to separate the compressor cavity and the evaporator cavity; a partition structure for separating the compressor cavity and the condenser cavity; a water tray located on the lower side of the evaporator, one end of which is connected to the partition structure, working together with the partition structure to separate the compressor cavity and the condenser cavity; and an integrally formed extension at the bottom of the water tray, which, together with the first partition plate, separates the compressor cavity and the evaporator cavity.

[0008] In some embodiments of this application, the housing includes a second partition, one end of which is connected to the end of the evaporator and the other end to the end of the condenser; the outer casing of the condenser fan has an outwardly extending partition portion, which, together with the second partition and a portion of the condenser fan outer casing, constitutes the separation structure. By using the condenser fan outer casing and its extending partition portion as part of the separation structure separating the compressor cavity and the condenser side cavity, there is no need to set up a separate partition, reducing the number of parts and maximizing the use of internal space, making the layout of the entire device more compact.

[0009] In some embodiments of this application, the water receiving tray includes a first extension region extending from the end of the evaporator along the length of the casing; a portion of the bottom edge of the second partition is connected to the side wall of the water receiving tray in the first extension region. This connection method allows the water receiving tray to bear the installation positioning and support of a portion of the second partition, and the water receiving tray can be firmly integrated with the second partition and the evaporator, improving the structural rigidity of the entire machine.

[0010] In some embodiments of this application, the side wall of the water receiving tray is provided with an upwardly protruding fixing part, and the fixing part is fixedly connected to the second partition plate by fasteners. The water receiving tray and the second partition plate are locked together by fasteners, ensuring the reliability and consistency of the connection.

[0011] In some embodiments of this application, the bottom edge of the second partition forms a sealing fit with the sidewall of the first extension region. After the second partition is connected to the water receiving tray, the bottom edge of the second partition can be tightly abutted against the sidewall of the first extension region to prevent air leakage between the second partition and the water receiving tray.

[0012] In some embodiments of this application, the drip tray and the extension are manufactured using an integrated injection molding process. This integrated injection molding process ensures seamless connection between the various parts of the drip tray, eliminating the risk of leakage; simultaneously, it offers high production efficiency, controllable costs, and good dimensional consistency.

[0013] In some embodiments of this application, the bottom of the drip tray is inclined downwards along the length of the casing towards the first extended area. This inclined design of the drip tray allows gravity to naturally collect condensate into the first extended area, facilitating subsequent drainage and preventing water accumulation.

[0014] In some embodiments of this application, the water receiving tray further includes a second extending region extending from the first extending region into the compressor cavity. By increasing the volume of the water receiving tray, a buffer water storage area is provided for the equipment, which can effectively cope with the condition of generating a large amount of condensate in a short period of time, thereby improving the reliability of operation.

[0015] In some embodiments of this application, a vibration damping pad is provided on the bottom plate of the housing, and the extension is press-fitted onto the vibration damping pad. By adding a vibration damping pad at the extension of the water tray, the vibration transmitted from the compressor to the bottom plate can be effectively absorbed and isolated, reducing the structural resonance of the entire machine and decreasing noise.

[0016] In some embodiments of this application, the water receiving tray is made of flame-retardant composite material, and a metal reinforcing member is embedded in the extension of the water receiving tray. The flame-retardant composite material improves the overall safety performance of the machine; the metal reinforcing member improves the rigidity and strength of the extension of the water receiving tray, enabling it to reliably bear the functions of separation and support for a long time without deformation or breakage due to temperature changes or long-term stress.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are: In the kitchen air conditioning unit described in the above embodiments, the drip tray and its integrally formed extension are directly used as part of the structure separating the compressor chamber and the evaporator chamber. This allows for a more airtight isolation between the relevant chambers, enhancing the heat insulation effect while reducing noise problems caused by gaps in traditional panel splicing. Furthermore, the elimination of the need for a separate partition for this area not only reduces the number of parts and simplifies the assembly process but also maximizes the use of internal space, resulting in a more compact overall equipment layout.

[0018] Furthermore, the internal space is divided into three relatively independent cavities by means of the first partition, the partition structure, and the composite isolation structure consisting of the water receiving tray. The compressor can be independently sealed in the compressor cavity, thereby efficiently achieving heat insulation and sound insulation for the compressor. At the same time, there is no need to add an additional isolation component to the compressor, which further saves internal space and further reduces the size of the whole machine.

In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0028] like Figures 1-12 As shown, some embodiments of this application provide a kitchen air conditioning device that, through an integrated structural design, achieves excellent heat insulation and noise reduction for the compressor while meeting the stringent miniaturization requirements of kitchen air conditioning, without increasing or even reducing the number of parts.

[0029] See Figures 1-3The kitchen air conditioning equipment mainly includes a casing 10 and a refrigeration system located inside the casing 10.

[0030] The housing 10 provides structural support and protection for the internal components of the entire air conditioner. The housing 10 consists of a top plate 11, a bottom plate 12, a side plate 13, and a back plate 14.

[0031] The refrigeration system is the core of the air conditioning cooling function, and mainly includes a compressor 23, a condenser 22, a throttling device and an evaporator 21 connected in sequence by refrigeration pipes.

[0032] Compressor 23 is the power core of the refrigeration system, responsible for compressing the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant.

[0033] The condenser 22 is a heat exchanger where the high-temperature, high-pressure gaseous refrigerant releases heat to the surrounding environment and condenses itself into a high-pressure, medium-temperature liquid refrigerant.

[0034] Throttling devices, such as capillary tubes or expansion valves, are responsible for throttling and reducing the pressure of high-pressure liquid refrigerant, turning it into a low-temperature, low-pressure liquid refrigerant, in preparation for subsequent evaporation and heat absorption.

[0035] Evaporator 21 is another heat exchanger where low-temperature, low-pressure liquid refrigerant evaporates, absorbs heat from the surrounding environment (such as kitchen air that needs to be cooled), and becomes low-temperature, low-pressure gaseous refrigerant, which is then drawn back into compressor 23 to complete a refrigeration cycle.

[0036] The casing 10 is equipped with an evaporator-side return air inlet a and an evaporator-side outlet c. Indoor air is driven by the evaporator fan 40, drawn in from the evaporator-side return air inlet a, flows over the surface of the evaporator 21, is cooled down, and then blown out from the evaporator-side outlet c to provide cool air for the kitchen.

[0037] The casing 10 is also equipped with a condenser-side return air inlet b. Air is driven by the condenser fan 50 and drawn in from the condenser-side return air inlet b. It flows over the surface of the condenser 22, carrying away the heat released by the refrigerant and forming a high-temperature heat dissipation airflow, which is blown out from the condenser-side outlet d.

[0038] The core technical solution of this application lies in the division and separation of the internal space of the casing 10. By integrating the water tray 60 into the structure, it not only serves the basic function of receiving condensate water, but also plays the role of separating the internal cavity.

[0039] like Figure 4 As shown, the interior of the housing 10 is divided into three independent cavities: compressor cavity B, evaporator cavity A, and condenser cavity C.

[0040] Compressor cavity B is located in the middle and is used to house compressor 23 in the refrigeration system, such as Figure 4Yellow area.

[0041] The evaporator-side cavity A is located on one side, for example, the left side, and it houses the evaporator 21 and the evaporation fan 40. Figure 4 Blue area.

[0042] The condenser-side cavity C is located on the other side, for example, the right side, and it houses the condenser 22 and the condenser fan 50. (Example) Figure 4 Red area.

[0043] To achieve effective separation of these three cavities, such as Figure 3 As shown, a first partition 31 is provided inside the casing to separate the compressor cavity B and the evaporator cavity A.

[0044] Specifically, one end edge of the first partition 31 is connected to the end of the evaporator 21, for example, to the rear edge of one side end plate of the evaporator 21; the other end can be connected to the back plate or side plate of the housing 10, thereby forming an airtight physical barrier that separates the compressor cavity B and the evaporator side cavity A.

[0045] The housing 10 also includes a partition structure that separates the compressor cavity B from the condenser side cavity C. The partition structure includes a second partition 32, the outer casing 51 of the condenser fan 50, etc., and a detailed structural description follows.

[0046] A drip tray 60 is positioned directly below the evaporator 21 to collect condensate generated on its surface. The drip tray has a dual function of separating the chambers.

[0047] like Figure 5 and Figure 6 As shown, the first separating function of the water tray 60 is to participate in separating the compressor cavity B and the condenser side cavity C.

[0048] Specifically, one end of the water receiving tray 60, for example, the side wall near the condenser side cavity C, is connected to the lower part of the aforementioned partition structure.

[0049] This connection can be achieved through snap-fit, screw-fit, or adhesive bonding with heat fusion to ensure airtightness. Through this connection, the water tray 60 itself becomes an extension and complement to the partition structure at the bottom of the equipment, working together to form a complete airflow barrier.

[0050] The second dividing function of the water tray 60 is to participate in separating the compressor cavity B and the evaporator cavity A.

[0051] like Figure 6 and Figure 7 As shown, at the bottom of the water receiving tray 60, an extension 61 extending downward is integrally formed by processes such as injection molding.

[0052] The extension 61 can be a continuous wall-like structure or a number of rib-like or column-like structures.

[0053] The height of the extension 61 allows its lower end face to contact and be supported on the base plate of the housing 10.

[0054] Meanwhile, the extension 61 is aligned with or overlaps the lower side of the first partition 31.

[0055] In this way, the compressor cavity B and the evaporator cavity A are separated by the combined action of the first partition 31 and the extension 61 of the water receiving tray 60.

[0056] In addition, the extension 61 itself also serves to support the entire evaporator-drain tray assembly, improving the stability of the structure.

[0057] The aforementioned kitchen air conditioning equipment uses the water tray 60 and the extension 61 extending from it as part of the separation between the compressor cavity B and the evaporator cavity A, so that the evaporator cavity can form a sealed cavity. This not only provides heat insulation but also reduces noise problems caused by gaps. At the same time, there is no need to set up a separate partition, which not only reduces the number of parts and simplifies the assembly process but also maximizes the use of internal space, making the layout of the entire equipment more compact and realizing the miniaturization and thinning design of the kitchen air conditioning equipment.

[0058] Furthermore, the internal space is divided into three relatively independent cavities by the first partition 31, the partition structure, and the composite isolation structure composed of the water receiving tray. The compressor 23 can be independently enclosed in the compressor cavity B, thereby achieving heat insulation and sound insulation for the compressor 23. There is no need to add an additional isolation component to the compressor 23, further saving internal space and further reducing the overall size of the machine.

[0059] In some embodiments, such as Figure 3 As shown, a second partition 32 is provided inside the casing.

[0060] One end of the second partition 32 is connected to the end of the evaporator 21, for example, to the front edge of one side end plate of the evaporator 21; the other end is connected to the end of the condenser 22, for example, to the front edge of one side end plate of the condenser 22.

[0061] See Figure 3 and Figure 9 The condenser fan 50 has an outwardly extending partition 52 integrally formed or additionally connected to its outer casing 51, the partition 52 pointing towards the end of the second partition 32 or the condenser 22.

[0062] The second partition 32, a part of the housing 51 of the condenser fan 50, and the partition 52 together form a separation structure that effectively separates the compressor cavity B and the condenser side cavity C.

[0063] By incorporating the housing 51 of the condenser fan 50 and its extended partition 52 as part of the partition structure separating the compressor cavity B and the condenser side cavity C, there is no need to set up a separate partition, which reduces the number of parts, simplifies the assembly process, and, more importantly, maximizes the use of internal space, making the layout of the entire device more compact.

[0064] In other embodiments, the partition structure may also be a single, independently set partition.

[0065] In some embodiments, the connection method between the second partition 32 and the water receiving tray 60 has been optimized.

[0066] In some embodiments, such as Figure 8 As shown, the water tray 60 includes a first extended region 62.

[0067] The first extended region 62 refers to the main body of the water tray 60, which extends from a certain end of the evaporator 21 (e.g., the end that connects to the second partition 32) and continues along the length direction (e.g., the left-right direction) of the casing 10.

[0068] The second partition 32 forms a composite connection with the evaporator 21 and the water receiving tray 60.

[0069] Specifically, the second partition 32 is connected to the end plate of the evaporator 21, and then the bottom edge of the second partition 32 is connected to the side wall of the first extension area 62 of the water receiving tray 60.

[0070] This connection method allows the water tray 60 to partially support and position the second partition 32. The water tray 60 can be firmly integrated with the second partition 32 and the evaporator, improving the overall structural rigidity of the unit.

[0071] In some embodiments, refer to Figure 4 One or more upwardly protruding fixing parts 64 are integrally formed on the side wall of the first extension region 62.

[0072] The fixing part 64 can be a boss, a lug, or a pin seat, with a through hole or threaded hole pre-drilled on it for fasteners to pass through. A through hole is also opened at the corresponding position of the second partition 32.

[0073] During assembly, the second partition 32 is aligned with the fixing part 64 and locked in place by fasteners (such as self-tapping screws or bolts) 96. This fixing method ensures the reliability and consistency of the connection and facilitates mass production.

[0074] In other embodiments, snap-fit ​​or adhesive methods may also be used for connection.

[0075] In some embodiments, in order to prevent air leakage between the second partition 32 and the water tray 60, a sealing fit is formed between the bottom edge of the second partition and the sidewall of the first extension region.

[0076] Specifically, the sealing fit can be a direct contact support, i.e., the bottom edge of the second partition 32 is directly pressed against the side wall of the water receiving tray 60; or there is a very small, designed gap between the bottom edge of the second partition 32 and the side wall of the water receiving tray 60, but airflow cannot pass through; or the two are closely adjacent to each other through a sealing element, such as a sealing strip or sealant sandwiched between them.

[0077] In some embodiments, the drip tray 60 and its extension 61 are preferably manufactured using an injection molding process.

[0078] By selecting suitable engineering plastics, a complete part including the main body of the water tray, the extension 61, and various connecting structures (such as the fixing part 64) can be obtained through one injection molding.

[0079] The injection molding process ensures seamless connection between parts, eliminating the risk of leakage; at the same time, it has high production efficiency, controllable cost, good dimensional consistency, and is suitable for mass production.

[0080] In some embodiments, the device is also equipped with a drain pump 91 to enable active drainage.

[0081] The drain pump 91 is preferably located within the first extension area 62 of the water receiving tray.

[0082] The first extension area 62 provides a dedicated installation space for the drain pump 91 that does not interfere with components such as the evaporator.

[0083] To facilitate the efficient operation of the drainage pump 91, the bottom of the water receiving tray 60 is designed to be inclined downward toward the first extension area 62.

[0084] In this way, the condensate generated at various points in the evaporator 21 will naturally flow to and collect in the first extended area 62, which is the lowest point, under the action of gravity, so that the drain pump 91 can completely and thoroughly extract it.

[0085] In other embodiments, the device may not be equipped with a drain pump 91, but instead drains naturally by gravity through a drain outlet at the bottom of the first extension region 62.

[0086] In some embodiments, the purpose is to increase the water storage capacity of the water receiving tray and improve the safety of the equipment in extreme working conditions.

[0087] See Figure 8 The water tray 60 also includes a second extension region 63. The second extension region 63 refers to a portion of the water tray that extends from the first extension region 62 toward the compressor cavity B.

[0088] The second extension area 63 utilizes part of the space at the bottom of the compressor cavity B, which increases the total volume of the water receiving tray. The increased volume can act as a buffer to prevent condensate from overflowing in the event of a large amount of condensate generated in a short period of time or a temporary failure of the drain pump, thereby improving the operational reliability of the equipment.

[0089] In some embodiments, the water receiving tray 60 is further provided with a water level detection component 92 for real-time monitoring of the water level inside the water receiving tray 60.

[0090] The water level detection component 92 can be a float switch, a reed switch sensor, or an optical sensor.

[0091] The water level signal detected by the water level detection component 92 can be sent to the controller of the equipment to realize the automatic start and stop control of the drainage pump 91, or to trigger an alarm and instruct the air conditioning equipment to stop operating when the water level exceeds the safety threshold, so as to prevent water leakage accidents.

[0092] In some embodiments, a vibration damping pad is pre-attached or placed on the bottom plate of the housing 10 at the position corresponding to the extension 61.

[0093] The material of the vibration damping pad can be EPDM foam, nitrile rubber, or other polymer materials with good elasticity.

[0094] During assembly, the lower end face of the extension of the water receiving tray 60 abuts against and moderately compresses the vibration damping pad.

[0095] The water tray 60 is press-fitted onto the vibration damping pad, which not only provides reliable support but also effectively absorbs and isolates the vibration generated by the compressor 23 and transmitted through the casing 10. This cuts off the path of vibration transmission to the evaporator-water tray assembly, avoids noise caused by structural resonance, and improves the overall quietness of the machine.

[0096] In other embodiments, the extension 61 may also be directly and rigidly connected to the base plate of the housing.

[0097] In some embodiments, the materials and structural strength of the docking water tray 60 have been enhanced.

[0098] The water tray 60 is preferably made of flame-retardant composite material to improve the overall safety performance of the machine.

[0099] In some embodiments, the extension 61 of the drip tray 60 is embedded with a metal reinforcement.

[0100] Metal reinforcements can be one or more steel bars, or a stamped steel plate.

[0101] Before injection molding, the metal reinforcement is pre-placed in the mold, and then injection molding is performed so that it is completely covered by plastic to form a whole.

[0102] The metal reinforcement greatly improves the rigidity and strength of the water tray extension 61, enabling it to reliably perform the functions of separation and support for a long time without deformation or breakage due to temperature changes or long-term stress.

[0103] In some embodiments, the evaporator fan 40 and the condenser fan 50 are centrifugal fans.

[0104] Compared with common axial fans, centrifugal fans can generate higher air pressure in a smaller volume, ensuring sufficient air volume to pass through the heat exchanger; at the same time, centrifugal fans are smaller in size, which is more conducive to the miniaturization design of the whole machine.

[0105] In some embodiments, in the evaporation side cavity A, the evaporation fan 40 is located on the air outlet side of the evaporator 21.

[0106] This means that the air first flows through the evaporator 21, is cooled, and then is drawn in and sent out by the evaporator fan 40.

[0107] Compared to a blower-type layout, this exhaust-type layout allows the airflow to be more evenly distributed across the entire windward surface of the evaporator 21 when it enters, avoiding areas of concentrated airflow and thus improving heat exchange efficiency.

[0108] Similarly, in the condenser side cavity C, the condenser fan 50 is located on the air outlet side of the condenser 22, which also achieves the same effect.

[0109] In other embodiments, depending on the specific duct design and airflow and pressure requirements, the evaporator fan 40 or the condenser fan 50 may also be an axial flow fan or a mixed flow fan.

[0110] In some embodiments, see Figure 10 The first partition 31 also serves to guide the return airflow.

[0111] For example, such as Figure 10The evaporator-side chamber A, compressor-side chamber B, and condenser-side chamber C are arranged sequentially from left to right. The evaporator 21 is arranged along the left-right direction and is located in front of the evaporator-side chamber A. Its length is relatively large to provide sufficient heat exchange area. The evaporator fan 40 (preferably a centrifugal fan) is arranged close to the left side plate of the casing 10, and its volute air inlet faces to the right (i.e., towards the inside of the casing 10).

[0112] In order to efficiently deliver the airflow from the large evaporator 21 to the fan inlet on its side, which has a much smaller opening area, the first partition 31 is designed as a one-piece bent structure.

[0113] Specifically, the first partition 31 includes a first section 311 and a second section 312 that are bent and connected at a preset angle.

[0114] One end of the first section 311 is connected to the end plate of the evaporator 21 by means of screws, clips or welding; while the second section 312 is located near the air inlet of the evaporator fan 40.

[0115] The first section 311 and the second section 312, which are bent and connected, together form a guide channel for converging the airflow from the evaporator 21 and guiding it to the air inlet of the evaporator fan 40.

[0116] Specifically, the wide airflow flowing out of the entire length of the evaporator 21 is converged and guided by the inclined first section 311 when it flows towards the evaporator fan 40, and then smoothly transitions to the air inlet area aligned with the second section 312. This avoids the airflow from being chaotic and turbulent in the inlet cavity of the fan, reduces aerodynamic noise, and minimizes wind resistance loss.

[0117] In some embodiments, the connection between the first segment 311 and the second segment 312 is a smoothly transitioning arc to further reduce wind resistance.

[0118] In some embodiments, to further optimize airflow organization and prevent air leakage, such as Figure 11 As shown, a third partition 33 and a fourth partition 34 are also added inside the housing 10.

[0119] The third partition 33 is located on the outside of the evaporation side cavity A. One end of it is connected to the end of the evaporator 21 away from the second partition 32 (i.e., the left end), and the other end is connected to the side wall of the housing 10.

[0120] In this way, the third partition 33, the first partition 31, and part of the casing 10 (such as the top cover and the bottom plate) together define a clearly defined evaporator-side return air duct.

[0121] All air entering from the evaporator-side return air inlet is forcibly guided through this air duct and eventually passes through the evaporator 21, eliminating the possibility of some airflow short-circuiting from the side of the evaporator 21 to the evaporator fan 40.

[0122] Similarly, the fourth partition 34 is located on the outside of the condenser side cavity C. One end of it is connected to the end of the condenser 22 away from the second partition 32 (i.e., the right end), and the other end is connected to the side wall of the housing 10.

[0123] The fourth partition 34, together with the partition structure and part of the casing 10, defines the return air duct on the condenser side, thus preventing airflow short-circuiting.

[0124] In some embodiments, such as Figure 2 As shown, the air conditioning equipment also includes an electrical control box 70, which contains electronic components such as circuit boards, relays, and sensor interfaces for controlling the operation of the equipment.

[0125] The control box 70 is fixedly installed inside the condenser side cavity C, and its position is preferably above the condenser 22.

[0126] The electrical control box 70 is positioned above the condenser 22. On the one hand, the space above the condenser 22 is usually quite open, so placing the electrical control box 70 in this space will not interfere with other large components.

[0127] On the other hand, the airflow driven by the condenser fan 50 flows through the entire condenser side cavity C, and the electrical control box 70 placed here can be naturally convectively cooled by the flowing air, which helps the electronic components inside the box to maintain a suitable operating temperature and improves the reliability of the electrical control system.

[0128] In some embodiments, please refer to Figure 1 and Figure 2 The front side of the housing 10 is provided with a panel assembly 80, which is the appearance part of the device and the human-machine interface.

[0129] The panel assembly 80 has grilles or openings for air circulation, specifically including an evaporator-side return air inlet a, a condenser-side return air inlet b, and an evaporator-side outlet air inlet c.

[0130] Evaporator-side return air vent a is used to draw in air from the kitchen for cooling. Condenser-side return air vent b is used to draw in air to dissipate heat from the condenser 22.

[0131] The evaporator-side air outlet c is used to deliver the cooled air. The evaporator-side air outlet c is located on the lower side of the panel assembly 80 and is opened along the length of the housing. The volute air outlet 41 of the evaporator fan 40 can extend along the length of the housing to form an air outlet duct that communicates with the evaporator-side air outlet.

[0132] In some embodiments, an air guide assembly is provided at the evaporator-side air outlet to control the air outlet direction.

[0133] In some embodiments, such as Figure 12 As shown, in order to achieve an aesthetically pleasing embedded installation, the device also includes at least one mounting bracket 110.

[0134] On the outer surface of the housing 10, such as the back, bottom or top, a groove 15 is integrally formed by stamping.

[0135] The shape and size of the fixing bracket 110 match the groove 15.

[0136] like Figure 12 As shown, the fixed bracket 110 is an L-shaped bracket, and the groove 15 is correspondingly opened on the back and bottom surfaces of the housing 10.

[0137] During installation, the installer first fixes the mounting bracket 110 to the inner wall of the cabinet or wall surface, then pushes the kitchen air conditioner into the cabinet or hangs it on the wall, so that the groove 15 on the housing 10 is aligned and embedded with the mounting bracket 110. Finally, the mounting bracket 110 is fixed to the housing 10 from the bottom of the equipment using screws or other fasteners.

[0138] Since the entire mounting bracket 110 is embedded inside the groove 15, its highest point will not protrude from the outer surface contour of the housing 10. This allows the surface of the housing 10 to fit smoothly against the inner wall of the cabinet or wall, achieving a concealed installation effect. This not only enhances the overall aesthetics of the kitchen but also further reduces the space occupied by the entire unit.
