[0006] The evaporator assembly, the water tray and the air supply fan are all disposed in the housing and arranged in sequence from top to bottom; the housing has an inlet and an outlet connected to the indoor environment, a cold air flow channel is formed between the inlet and the outlet, and the air supply fan is configured to blow air from the inlet to the outlet along the cold air flow channel;

[0007] The cold air flow channel comprises a vertically penetrating air channel, which is located on the same side of the water receiving tray and the evaporator assembly in the circumferential direction along a height direction perpendicular to the housing;

[0008] The air inlet end of the air duct is connected to the inlet fluid, the evaporator assembly is located on the flow path of the inlet fluid, the air outlet end of the air duct is connected to the air inlet end of the air supply fan; the air outlet end of the air supply fan is connected to the outlet fluid.

[0009] In this way, the air duct is formed on the same side of the water collecting pan and the evaporator assembly, and the air flow can be smoothly guided to the air inlet end of the air supply fan after being cooled by the evaporator assembly, thereby reducing the resistance and eddy current of the air flow, improving the efficiency of air flow, and enhancing the cooling effect; in addition, the arrangement of the evaporator assembly, the water collecting pan and the air supply fan forms a vertically connected air duct, which helps to optimize the air flow path and reduce the air flow resistance.

[0010] In a feasible implementation manner, the water receiving tray, the evaporator assembly and adjacent inner walls of the housing are spaced apart to form the air duct.

[0011] In this way, on the one hand, this design utilizes the spatial layout inside the equipment to effectively guide the airflow along the optimal path, reduce the resistance and eddy current of the airflow, and improve the efficiency of the airflow; on the other hand, the space between the inner wall of the outer shell is used to form an air duct, without the need for an additional air-guiding structure, making the design of the entire device more compact, saving internal space, and simplifying the manufacturing and assembly process.

[0012] In a feasible embodiment, the shell has relative front side walls and rear side walls, the outlet is opened on the front side wall, the air outlet end of the air supply fan is close to the front side wall, and at least part of the air duct is located on the side of the air supply fan away from the air outlet end; wherein a first air duct is formed between the water receiving tray, the evaporator assembly and the rear side wall of the shell.

[0013] In this way, the design of the first air duct allows the air cooled by the evaporator assembly to be quickly and effectively guided to the air outlet of the air outlet fan, which helps to reduce the indoor temperature more quickly, thereby improving the overall cooling effect of the air conditioner.

[0014] In an achievable embodiment, the housing has a left side wall and a right side wall opposite to each other, and the air inlet end of the air supply fan faces at least one of the left side wall and the right side wall;

[0015] The air inlet end is spaced apart from at least one of the left side wall and the right side wall, and a second air duct is formed between the air inlet end and at least one of the left side wall and the right side wall.

[0016] In this way, utilizing the spatial layout inside the device helps ensure that the airflow flows along the optimal path, improves the uniformity of air flow, reduces airflow resistance and eddy currents, improves air flow efficiency, and also helps reduce noise during operation of the air conditioner. The design of the air inlet facing at least one of the left wall and the right wall provides greater flexibility to adapt to different installation environments and spatial layout requirements.

[0017] In an achievable embodiment, along the direction from the front side wall to the rear side wall, the evaporator assembly includes two groups of evaporator units arranged side by side, and the longitudinal cross-sections of the two groups of evaporator units are V-shaped;

[0018] The top of the evaporator assembly forms an air inlet side, and the two groups of evaporator units respectively form air outlet sides of the evaporator assembly.

[0019] This helps to increase the contact area between the air and the surface of the evaporator assembly, thereby enhancing the heat exchange efficiency and allowing the air to be cooled more quickly.

[0020] In a feasible embodiment, the evaporator assembly includes a first evaporator unit, the first evaporator unit is located on a side close to the first air duct, and the first evaporator unit includes a plurality of first fins; the outer contours of the plurality of first fins form a first air outlet side.

[0021] This helps guide the airflow through the first evaporator unit more smoothly.

[0022] In a feasible implementation, the outer contour of the first fin is inclined to form a first inclined surface, and the first inclined surface is inclined from the bottom to the top of the evaporator assembly to a side away from the central axis of the evaporator assembly.

[0023] In this way, the design of the first inclined surface allows condensed water to naturally flow along the first inclined surface to the water receiving pan, reducing the accumulation of condensed water on the surface of the evaporator assembly and the risk of water droplets splashing, thereby improving the operating efficiency and safety of the kitchen air conditioner.

[0024] In a feasible implementation, on a side close to the first air duct, an edge of an orthographic projection of the water receiving tray on a preset horizontal plane does not exceed an edge of an orthographic projection of the first inclined surface on the preset horizontal plane.

[0025] In this way, condensed water can be effectively prevented from entering the first air duct, which helps to ensure the dry state of the first air duct; at the same time, the water receiving tray will not block the air inlet duct of the evaporator assembly, thereby improving the heat exchange efficiency.

[0026] In an achievable embodiment, the evaporator assembly includes a second evaporator unit, the second evaporator unit is located on a side away from the first air duct, the second evaporator unit includes a plurality of second fins, and the outer contours of the plurality of second fins form a second air outlet side;

[0027] The outer contour of the second fin is inclined to form a second inclined surface, and the second inclined surface is inclined from the bottom to the top of the evaporator assembly to a side away from the central axis of the evaporator assembly.

[0028] In this way, the design of the second inclined surface allows condensed water to flow naturally along the second inclined surface to the water receiving pan, reducing the accumulation of condensed water on the surface of the evaporator assembly and the risk of water droplets splashing, thereby improving the operating efficiency and safety of the kitchen air conditioner.

[0029] In an achievable embodiment, the water receiving tray includes a tray bottom and a side wall arranged on the periphery of the tray bottom; the water receiving tray further includes an air guide wall on a side close to the air duct, wherein a first end of the air guide wall is connected to an end of the side wall away from the tray bottom, and a second end of the air guide wall extends relative to the first end toward a side close to the water receiving tray;

[0030] Among them, in the horizontal direction, the second end of the wind guide wall gradually tilts from the dish mouth to the dish bottom, and gradually tilts toward the side away from the center of the water receiving dish. The wind guide wall is configured to guide the airflow in the air duct into the air inlet end of the air supply fan.

[0031] In this way, the design of the air guide wall effectively guides the airflow in the air duct into the air inlet end of the air supply fan through its inclined structure, reduces the turbulence and resistance of the airflow, and improves the flow efficiency of the airflow.

[0032] In an achievable embodiment, the number of the air supply fans includes a plurality, and the plurality of air supply fans are arranged at intervals along the direction from the left wall to the right wall, and the air inlet ends of the plurality of air supply fans are all connected to the air outlet end of the air duct;

[0033] Wherein, the wind guide wall is configured to guide the wind flow in the air duct into the air inlet ends of the multiple air supply fans, so that the wind flow blown out from the air outlet end of the air duct is diverted to the air inlet ends of the multiple air supply fans.

[0034] In this way, by arranging multiple air supply fans at intervals, it is possible to achieve a uniform distribution of airflow, avoiding the problem of airflow concentration caused by a single fan, thereby improving the air supply uniformity of the entire system; in addition, the use of multiple air supply fans can reduce the load of a single air supply fan, and at the same time, the number and position of the air supply fans can be flexibly adjusted according to actual needs to adapt to different air supply needs.

[0035] In an achievable implementation, the air supply fan comprises a drive motor and a wind wheel, the drive motor is provided with a drive shaft, and the wind wheel is provided at an axial end of the drive shaft;

[0036] The air inlet end of the air supply fan is located at the wind wheel, and the driving motor is configured to drive the wind wheel to rotate.

[0037] In this way, the design of directly connecting the drive motor to the wind wheel reduces the loss of the intermediate transmission mechanism and improves the efficiency of energy transfer.

[0038] In an achievable implementation, the number of the wind wheels includes at least two, and in the axial direction of the driving shaft, at least two wind wheels are connected to the driving shaft at intervals, and the driving motor is located between the at least two wind wheels;

[0039] At least two of the wind wheels have an air inlet end, and the drive motor is configured to drive at least two wind wheels to rotate simultaneously.

[0040] In this way, at least two wind wheels share the same drive motor, which can distribute the driving force more evenly, reduce the problem of axial imbalance, improve the efficiency of energy transfer, and make the system run more efficiently; in addition, the design of multiple wind wheels shares the load of the wind wheels, reduces the wear rate of a single wind wheel, and extends the service life of the air supply fan.

[0041] In one feasible embodiment, the number of the wind wheels includes two, the drive motor is located between the two wind wheels, both ends of the drive shaft pass through the drive motor respectively and are connected to the centers of the two wind wheels; the drive motor is configured to drive the two wind wheels to rotate simultaneously.

[0042] In this way, by driving two wind wheels at the same time with one drive motor, energy transfer is more direct and efficient, reducing the loss of intermediate transmission components and improving the utilization efficiency of the air supply fan. In addition, it helps to ensure the synchronous movement of the two wind wheels and avoid the problem of uneven airflow caused by inconsistent operation of multiple drive motors.

[0043] In a feasible embodiment, it also includes an electric control box, which is located below the air supply fan along the height direction of the shell; the electric control box is opposite to the air outlet end of the air duct so that the airflow blown out from the air outlet end of the air duct can be diverted to the surface of the electric control box.

[0044] In this way, the arrangement of the electric control box helps to reduce the impact of condensed water on the electric control box, reduce the risk of electrical components getting damp, and improve the safety and reliability of the electric control box; in addition, the airflow generated by the air supply fan can be used to actively dissipate the heat for the electric control box, which is beneficial to reduce the temperature of the circuit board inside the electric control box and improve its working stability and service life.

[0045] In a feasible implementation, it further includes a water tank. In the horizontal direction, the electric control box and the water tank are arranged side by side, and the water tank is located on the side of the electric control box; wherein the air outlet end of the air duct is located above the water tank.

[0046] In this way, the air outlet of the air duct not only provides heat dissipation for the electric control box, but also promotes the evaporation or temperature regulation of the water in the water tank through the airflow above the water tank. This multifunctional design of utilizing airflow improves the overall efficiency of the system.

[0047] In an achievable embodiment, a water diversion pipe is further included, the bottom surface of the water receiving tray is provided with a water outlet, the water tank and the water outlet of the water receiving tray are connected through the water diversion pipe, and the water diversion pipe is configured to divert condensed water in the water receiving tray into the water tank;

[0048] Wherein, in the height direction of the shell, the water outlet is located at the lowest position of the bottom surface of the water receiving tray.

[0049] In this way, the condensed water can flow quickly to the water outlet, minimizing the retention of the condensed water in the first water receiving member, thereby improving the discharge efficiency of the condensed water.

[0050] In an achievable embodiment, a drain pipe and a drain pump are further included, and a housing opening is provided at the top of the housing;

[0051] The inlet of the drain pipe is communicated with the drain pump, the outlet of the drain pipe is communicated with the housing, and the drain pump is configured to drive the condensed water in the water tank to be transported to the opening of the housing through the drain pipe.

[0052] In this way, the introduction of the drain pump significantly improves the condensate discharge capacity and ensures the efficient operation of the system. The design of the drain pipe reduces the risk of leakage when condensate flows between different components, provides additional protection and guidance, and reduces the possibility of water overflow within the system.

[0072] In the related art, the kitchen air conditioner includes an evaporator, a water tray and an air supply fan, wherein the water tray is used to collect condensed water generated by the evaporator, and the air supply fan is used to blow cold air outward to achieve cooling of the kitchen. However, in the related art, the air supply fan has a low air intake efficiency and a poor cooling effect.

[0073] In view of the above technical problems, the embodiment of the present application provides a kitchen air conditioner, including an evaporator assembly, a water tray and an air supply fan, wherein the cold air flow channel includes a vertically penetrating air channel, and the air channel is located on the same side of the water tray and the evaporator assembly in the circumferential direction. In this way, the airflow can be smoothly guided to the air inlet end of the air supply fan after cooling down through the evaporator assembly, reducing the resistance and vortex phenomenon of the airflow, and improving the efficiency of air flow, thereby maximizing the cold air intake efficiency of the air supply fan and improving the cooling effect.

[0074] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0075] Reference Figures 1 to 3 As shown, an embodiment of the present application provides a kitchen air conditioner, which includes a shell 100, an evaporator assembly 210, a water tray 310 and an air supply fan 220; the evaporator assembly 210, the water tray 310 and the air supply fan 220 are all arranged in the shell 100.

[0076] In the embodiment of the present application, the material of the housing 100 is not limited. For example, the housing 100 can be made of stainless steel, which has good corrosion resistance and heat resistance and is easy to clean and maintain; or the housing 100 can be made of aluminum alloy, which is light and has good corrosion resistance, good thermal conductivity, and can help dissipate heat. This embodiment does not limit this.

[0077] Exemplarily, the housing 100 includes a front panel 110 , a top panel 130 , and a plurality of side panels 120 connected end to end.

[0078] In the embodiment of the present application, the shape of the water receiving tray 310 is not limited, wherein the shape and size of the water receiving tray 310 can be determined according to the size of the evaporator assembly 210 and the expected flow rate of condensed water; in addition, the material of the water receiving tray 310 is not limited. For example, the water receiving tray 310 can be made of plastic material, which is light, corrosion-resistant, and easy to shape. This embodiment does not limit this.

[0079] In the embodiment of the present application, the arrangement positions of the evaporator assembly 210, the water receiving tray 310 and the air supply fan 220 are not limited. Figure 4 and Figure 5 As shown, the evaporator assembly 210, the water tray 310 and the air supply fan 220 are arranged in sequence from top to bottom. It can be understood that in the height direction of the housing 100, the water tray 310 is located between the evaporator assembly 210 and the air supply fan 220, and the air supply fan 220 is located below the water tray 310.

[0080] In this way, the water receiving tray 310 is located below the evaporator assembly 210, and can quickly collect condensed water to prevent water droplets from falling into other parts of the air-conditioning system, thereby ensuring that other components of the system are not affected by the condensed water.

[0081] The housing 100 has an inlet and an outlet connected to the indoor environment, a cold air flow channel is formed between the inlet and the outlet, and the air supply fan 220 is configured to blow the air flow from the inlet to the outlet along the cold air flow channel.

[0082] For example, in this embodiment, the positions of the inlet and the outlet are not limited. It is understandable that the inlet of the housing 100 is used for air intake, and the outlet is used for blowing out airflow. In this way, the air supply fan 220 blows the airflow from the inlet to the outlet, forming a continuous air circulation, effectively ensuring the effective flow and circulation of indoor air, and improving the overall efficiency of the kitchen air conditioner.

[0083] It should be noted that the outlet can be set on the front panel 110, and the front panel 110 is located on the front side of the kitchen air conditioner. In this way, direct airflow can be delivered, so that the cold air can quickly reach the main working area of ​​the kitchen, thereby improving the response speed of the kitchen air conditioner; on the other hand, the airflow is directly delivered from the front panel 110, which can form a more effective air circulation path and further improve the comfort of the kitchen environment; on another hand, the outlet design of the front panel 110 allows users to perform maintenance and cleaning more conveniently, thereby ensuring the long-term and efficient operation of the air-conditioning system.

[0084] It should be noted that the inlet can be set on the top plate 130 of the outer shell 100, so as to avoid occupying the side space of the kitchen, making the kitchen layout more flexible and improving the overall space utilization; at the same time, the inlet of the top plate 130 is far away from the user's working area, which helps to reduce the noise interference during the operation of the kitchen air conditioner and improve the user experience.

[0085] In the present application, refer to Figure 4 As shown, the cold air flow channel includes a vertically penetrating air channel 260 . Along a height direction perpendicular to the housing 100 , the air channel 260 is located on the same side of the water receiving tray 310 and the evaporator assembly 210 in the circumferential direction.

[0086] Among them, the air inlet end of the air duct 260 is connected to the imported fluid, the evaporator assembly 210 is located on the flow path of the imported fluid, the air outlet end of the air duct 260 is connected to the air inlet end 221 of the air supply fan 220; the air outlet end of the air supply fan 220 is connected to the outlet fluid.

[0087] It should be noted that vertical penetration means that the air duct 260 is a vertically extending channel that allows air flow to flow in a vertical direction. This design allows the air flow to flow in a vertical direction from top to bottom, which helps to reduce air flow resistance and improve air circulation efficiency.

[0088] In the embodiment of the present application, the air duct 260 is located on the same side of the water receiving pan 310 and the evaporator assembly 210 in the circumferential direction. In this way, after the air passes through the evaporator assembly 210 for heat exchange, it can directly enter the air duct 260 for vertical flow, which helps to optimize the air flow path and improve the heat exchange efficiency; in addition, it is beneficial to optimize the utilization of the internal space of the kitchen air conditioner, making the entire system more compact.

[0089] In addition, the evaporator assembly 210 is located on the flow path of the inlet fluid, which helps ensure that the air undergoes sufficient heat exchange through the evaporator assembly 210 before entering the air duct 260, thereby improving the heat exchange efficiency and allowing the air to be effectively cooled before entering the air duct 260.

[0090] In the embodiment of the present application, the air outlet end of the air duct 260 is connected to the air inlet end 221 of the air supply fan 220 to form a compact air flow circuit. This integrated design reduces intermediate links and improves the overall efficiency of the system.

[0091] It should be noted that the working principle of the evaporator assembly 210 is as follows: the refrigerant enters the coil under the action of the compressor. When the air passes through the evaporator assembly 210, the heat in the air is absorbed by the refrigerant. After absorbing the heat, the refrigerant evaporates and becomes gaseous, and the air is cooled. During the heat exchange process, the moisture in the air will condense on the surface of the evaporator assembly 210 to form condensed water.

[0092] Therefore, the kitchen air conditioner provided in the embodiment of the present application includes an evaporator assembly 210, a water receiving tray 310 and an air supply fan 220, and the cold air flow channel includes a vertically penetrating air duct 260, and the air duct 260 is located on the same side of the water receiving tray 310 and the evaporator assembly 210 in the circumferential direction. In this way, the airflow can be smoothly guided to the air inlet end 221 of the air supply fan 220 after cooling down through the evaporator assembly 210, reducing the resistance and vortex phenomenon of the airflow, improving the efficiency of air flow, thereby maximizing the cold air intake efficiency of the air supply fan 220 and improving the cooling effect.

[0093] In one possible implementation, referring to Figure 4As shown, the water receiving tray 310 , the evaporator assembly 210 and the adjacent inner wall of the housing 100 are spaced apart to form an air duct 260 .

[0094] In this way, on the one hand, this design utilizes the spatial layout inside the device to effectively guide the airflow along the optimal path, reduce the resistance and vortex phenomenon of the airflow, and improve the flow efficiency of the airflow; on the other hand, the space between the inner wall of the outer shell 100 is used to form an air duct 260, without the need for an additional air-guiding structure, making the design of the entire device more compact, saving internal space, and simplifying the manufacturing and assembly process.

[0095] In addition, the design of the air duct 260 in this embodiment helps to reduce the length and complexity of the air flow path, reduce the energy consumption of the air supply fan 220, and also reduce the turbulence and wind resistance of the air flow, thereby reducing operating noise.

[0096] In one possible implementation, referring to Figures 1 to 4 As shown, the housing 100 has a front side wall 140 and a rear side wall 150 opposite to each other, and the outlet is opened on the front side wall 140; the air outlet end of the air supply fan 220 is close to the front side wall 140, and at least part of the air duct 260 is located on the side of the air supply fan 220 away from the air outlet end.

[0097] Among them, refer to Figure 5 As shown, a first air duct 261 is formed between the water receiving tray 310 , the evaporator assembly 210 and the rear side wall 150 of the housing 100 .

[0098] It should be noted that the housing 100 includes a front panel 110, a top panel 130, a back panel 180, and a plurality of side panels 120 connected end to end. The front panel 110 is located at the front side of the housing 100, that is, the front panel 110 is the side facing the user, and the back panel 180 is located at the back side of the housing 100. It can be understood that the front side wall 140 is the inner wall of the front panel 110, and the rear side wall 150 is the inner wall of the back panel 180.

[0099] In the embodiment of the present application, the air outlet 222 of the air supply fan 220 is close to the front side wall 140, so that the cooled air flow can be quickly transported to the kitchen area, which helps to reduce the temperature of the kitchen in a short time and improve the comfort level; in addition, the design of the first air duct 261 allows the air cooled by the evaporator assembly 210 to be quickly and effectively guided to the air outlet 222 of the air supply fan 220, which helps to reduce the indoor temperature more quickly, thereby improving the overall cooling effect of the air conditioner.

[0100] In one possible implementation, referring to Figures 1 to 4 As shown, the housing 100 has a left side wall 160 and a right side wall 170 opposite to each other, and the air inlet end 221 of the air supply fan 220 faces at least one of the left side wall 160 and the right side wall 170 .

[0101] Among them, refer to Figure 5 As shown, the air inlet end 221 is spaced apart from at least one of the left side wall 160 and the right side wall 170 , and a second air duct 262 is formed between the air inlet end 221 and at least one of the left side wall 160 and the right side wall 170 .

[0102] For example, when there is one air inlet end 221 of the air supply fan 220, the air inlet end 221 may face the left side wall 160 or the right side wall 170; when there are multiple air inlet ends 221, the air inlet end 221 may face both the left side wall 160 and the right side wall 170. This embodiment does not limit this.

[0103] It can be understood that the housing 100 includes two side panels 120 arranged opposite to each other, the left side wall 160 is the inner wall of one of the side panels 120 , and the right side wall 170 is the inner wall of the other side panel 120 .

[0104] In this way, on the one hand, the air supply fan 220 can more effectively collect air from multiple directions, improve the efficiency of air flow, and help optimize air circulation; on the other hand, utilizing the spatial layout inside the equipment helps to ensure that the airflow flows along the optimal path, improves the uniformity of air flow, reduces air flow resistance and eddy currents, improves air flow efficiency, and also helps to reduce noise during air conditioning operation; on the other hand, the design of the air inlet end 221 facing at least one of the left side wall 160 and the right side wall 170 provides greater flexibility to adapt to different installation environments and spatial layout requirements.

[0105] Moreover, in the present embodiment, based on the first air duct 261, a second air duct 262 is further defined, and the wind flow direction in the first air duct 261 is different from the wind flow direction in the second air duct 262. In this way, the air supply fan 220 can inhale air from multiple directions, reduce dead corners and stagnation areas of air flow, and also help to reduce air flow turbulence and wind resistance, thereby helping to reduce operating noise.

[0106] In one possible implementation, referring to Figure 4 and Figure 5 As shown, along the direction from the front side wall 140 to the rear side wall 150, the evaporator assembly 210 includes two groups of evaporator units arranged side by side, and the longitudinal cross-sections of the two groups of evaporator units are V-shaped. The top of the evaporator assembly 210 forms the air inlet side, and the two groups of evaporator units respectively form the air outlet sides of the evaporator assembly 210.

[0107] In the embodiment of the present application, a top air intake method is adopted so that air can evenly enter the evaporator assembly 210 and be guided to the air outlet side through two V-shaped evaporator units.

[0108] The V-shaped evaporator units increase the contact area between the air and the surface of the evaporator assembly 210, thereby improving the heat exchange efficiency. When the air flows through the V-shaped channel, it fully exchanges heat with the two groups of evaporator units, thereby more effectively reducing the air temperature. In addition, when the air flows through the evaporator assembly 210, it can be evenly cooled to avoid local overheating or overcooling, ensure the uniformity of the air outlet temperature, and improve the comfort of the indoor environment.

[0109] At the same time, the V-shaped structure helps to provide better mechanical stability, reduce vibration and noise, and improve the reliability and service life of the system; moreover, it makes the various parts of the evaporator unit easier to access and clean, simplifying maintenance work.

[0110] In one possible implementation, referring to Figure 4 As shown, the evaporator assembly 210 includes a first evaporator unit 211 . The first evaporator unit 211 is located at a side close to the first air duct 261 . The first evaporator unit 211 includes a plurality of first fins.

[0111] In this way, multiple first fins provide a larger surface area, increasing the contact area between the air and the first evaporator unit 211, so that the air can be cooled more effectively when flowing through the first fins, thereby improving the heat exchange efficiency; moreover, the design of the first evaporator close to the first air duct 261 allows the cooled air to enter the air duct 260 for transportation, thereby reducing the complexity and resistance of the air flow path and improving the air circulation efficiency.

[0112] In this embodiment, the outer contours of multiple first fins form a first air outlet side, which helps to ensure that air can be discharged evenly from the first evaporator unit 211 and avoid local overheating or overcooling. At the same time, due to the improvement in heat exchange efficiency, the system can reach the set temperature in a shorter time, thereby reducing the operating time of the compressor of the air supply fan 220 and reducing energy consumption.

[0113] In a feasible implementation, the outer contour of the first fin is inclined to form a first inclined surface, and the first inclined surface is inclined from the bottom to the top of the evaporator assembly 210 to a side away from the central axis of the evaporator assembly 210 .

[0114] There is no limitation on the inclination angle of the first inclined surface, and it can be set according to actual needs.

[0115] In this way, the design of the first inclined surface allows condensed water to naturally flow along the first inclined surface to the water receiving tray 310, reducing the accumulation of condensed water on the surface of the evaporator assembly 210 and the risk of water droplets splashing, thereby improving the operating efficiency and safety of the kitchen air conditioner.

[0116] In addition, the air flow direction can be guided so that the air can pass through the evaporator assembly 210 more smoothly, reducing flow resistance and turbulence and improving air circulation efficiency; moreover, the inclined design helps to increase the path length of the air flow and enhance the contact time between the air and the first fin, thereby improving the heat exchange efficiency and allowing the air to be more fully cooled when flowing through the first fin.

[0117] In a feasible implementation, on the side close to the first air duct 261 , the edge of the orthographic projection of the water receiving tray 310 on the preset horizontal plane does not exceed the edge of the orthographic projection of the first inclined surface on the preset horizontal plane.

[0118] In the embodiment of the present application, there is no limitation on the preset horizontal plane. For example, taking a kitchen air conditioner as an example, the preset horizontal plane can be the bottom surface of the outer shell 100 of the kitchen air conditioner. The preset horizontal plane is used to analyze and compare the projection relationship of different components on the plane.

[0119] In the embodiment of the present application, orthographic projection can be understood as an image of a three-dimensional object on a plane, similar to the perspective of looking vertically downward from above.

[0120] The edge of the orthographic projection of the water tray 310 on the preset horizontal plane refers to the outer boundary of the orthographic projection of the water tray 310 on the preset horizontal plane. The edge of the orthographic projection of the first inclined surface on the preset horizontal plane refers to the outer boundary of the orthographic projection of the first inclined surface on the preset horizontal plane.

[0121] It should be noted that “not exceeding” means that: the projected edge of the water receiving tray 310 is completely located inside the projected edge of the first inclined surface; or it overlaps with the projected edge of the first inclined surface, but does not exceed the projected edge of the first inclined surface.

[0122] This design ensures that the water receiving tray 310 can effectively collect the condensed water flowing down from the first inclined surface, and there is no risk of condensed water overflowing from the water receiving tray 310; at the same time, it effectively prevents condensed water from entering the first air duct 261, which helps to ensure the dry state of the first air duct 261; at the same time, the water receiving tray 310 will not block the air intake of the evaporator assembly 210, thereby improving the heat exchange efficiency.

[0123] In one possible implementation, referring to Figure 4 As shown, the evaporator assembly 210 includes a second evaporator unit 212, which is located on a side away from the first air duct 261, and the second evaporator unit 212 includes a plurality of second fins, and the outer contours of the plurality of second fins form a second air outlet side; wherein the outer contours of the second fins are inclined and form a second inclined surface, and the second inclined surface is inclined from the bottom of the evaporator assembly 210 to the top to the side away from the central axis of the evaporator assembly 210.

[0124] In this way, the design of the second inclined surface allows condensed water to naturally flow along the second inclined surface to the water receiving tray 310, reducing the accumulation of condensed water on the surface of the evaporator assembly 210 and the risk of water droplets splashing, thereby improving the operating efficiency and safety of the kitchen air conditioner.

[0125] In addition, in the embodiment of the present application, the first evaporator unit 211 and the second evaporator unit 212 are arranged in such a way that the system can perform double-sided heat exchange simultaneously, thereby improving the overall heat exchange efficiency. The air can be cooled from two directions, thereby enhancing the refrigeration effect of the system.

[0126] In one possible implementation, referring to Fig. 9 As shown, the water receiving tray 310 includes a tray bottom 311 and a side wall 312 arranged on the periphery of the tray bottom 311; on the side close to the air duct 260, the water receiving tray 310 also includes an air guide wall 313, the first end of the air guide wall 313 is connected to the end of the side wall 312 away from the tray bottom 311, and the second end of the air guide wall 313 extends relative to the first end toward the side close to the water receiving tray 310.

[0127] Among them, in the horizontal direction, the second end of the wind guide wall 313 is gradually inclined from the dish mouth to the dish bottom 311, and gradually tilts toward the side away from the center of the water receiving tray 310. The wind guide wall 313 is configured to guide the airflow in the air duct 260 into the air inlet end 221 of the air supply fan 220.

[0128] In the embodiment of the present application, the wind guiding function of the wind guide wall 313 is integrated into the water receiving tray 310, so that the water receiving tray 310 is not only used to collect condensed water, but also can optimize the air flow by adding the wind guide wall 313; in addition, the system design is more compact, saving the internal space of the air conditioner.

[0129] In the embodiment of the present application, the second end of the air guide wall 313 is gradually inclined from the dish mouth to the dish bottom 311, away from the center of the water receiving tray 310. Such a design will not have a negative impact on the collection and discharge of condensed water.

[0130] In the embodiment of the present application, the air guide wall 313 is tilted to effectively guide the airflow in the air duct 260 into the air inlet end 221 of the air supply fan 220, thereby reducing the turbulence and resistance of the airflow and improving the flow efficiency of the airflow, so that the air supply fan 220 can operate under more ideal conditions, thereby improving the efficiency and performance of the air supply fan 220.

[0131] In a feasible implementation, the number of the air supply fans 220 includes a plurality, and the plurality of air supply fans 220 are arranged at intervals along the direction from the left side wall 160 to the right side wall 170 .

[0132] In the embodiment of the present application, there is no limitation on the number of the air supply fans 220. For example, the number of the air supply fans 220 may include two, three or more. This embodiment does not limit this.

[0133] In this way, the configuration of multiple air supply fans 220 can achieve uniform distribution of airflow, avoid the problem of airflow concentration caused by a single fan, and thus improve the air supply uniformity of the entire system; in addition, the use of multiple air supply fans 220 can reduce the load of a single air supply fan 220, and at the same time, the number and position of the air supply fans 220 can be flexibly adjusted according to actual needs to adapt to different air supply needs; moreover, if one of the air supply fans 220 fails, the other air supply fans 220 can continue to work to ensure the continuous operation and reliability of the system.

[0134] In the embodiment of the present application, the air inlet ends 221 of multiple air supply fans 220 are all connected to the air outlet ends of the air duct 260. In this way, uniform air flow distribution can be achieved, ensuring that each air supply fan 220 can receive air flow, which helps to improve the uniform temperature and comfort of the indoor environment.

[0135] It should be noted that since the wind guide wall 313 is set to be inclined downward, the wind guide wall 313 can guide the airflow in the air duct 260 to enter the air inlet end 221 of multiple air supply fans 220, so that the airflow blown out from the air outlet end of the air duct 260 is diverted to the air inlet end 221 of multiple air supply fans 220.

[0136] In this way, during the flow of air, the effective combination of the air guide wall 313, the air duct 260 and the air supply fan 220 is conducive to optimizing the airflow path, reducing the turbulence and resistance of the airflow when entering the air supply fan 220, and improving the air flow efficiency.

[0137] In one feasible embodiment, the air supply fan 220 may include a drive motor and a wind wheel, the drive motor is provided with a drive shaft, and the wind wheel is arranged at the axial end of the drive shaft; the air inlet end 221 of the air supply fan 220 is located at the wind wheel, and the drive motor is configured to drive the wind wheel to rotate.

[0138] It can be understood that the drive motor is the power source of the air supply fan 220. It converts electrical energy into mechanical energy to generate rotational motion. The core component of the drive motor is the drive shaft, which is the part that outputs power from the drive motor.

[0139] Among them, the drive shaft is connected to the rotating part of the drive motor and transmits the rotational motion of the drive motor to the wind wheel. The rotation speed and direction of the drive shaft are controlled by the drive motor and can usually be changed by adjusting the input current or voltage of the drive motor.

[0140] The wind wheel is installed at the axial end of the driving shaft. The wind wheel is usually composed of a plurality of blades. The design of these blades enables the air to flow effectively when the wind wheel rotates. The air inlet end 221 of the air supply fan 220 is located at the wind wheel. When the wind wheel rotates, the blades exert force on the surrounding air to generate a negative pressure area, thereby sucking in air. As the wind wheel rotates, the air is sucked into the air inlet end 221 and accelerated by the blades of the wind wheel, and finally discharged from the air outlet end 222 of the air supply fan 220. This process realizes the flow and transportation of air.

[0141] In the embodiment of the present application, the design of directly connecting the drive motor to the wind wheel is also beneficial to reducing the loss of the intermediate transmission mechanism and improving the efficiency of energy transfer.

[0142] In one feasible embodiment, the number of wind wheels may include at least two, at least two wind wheels are connected to the drive shaft at intervals in the axial direction of the drive shaft, and the drive motor is located between the at least two wind wheels; at least two wind wheels have an air inlet end 221, and the drive motor is configured to drive at least two wind wheels to rotate simultaneously.

[0143] Exemplarily, the number of wind wheels may be two, three or more, which is not limited in this embodiment.

[0144] In this way, at least two wind wheels share the same drive motor, which can distribute the driving force more evenly, reduce the problem of axial imbalance, improve the efficiency of energy transfer, and make the system run more efficiently; in addition, the design of multiple wind wheels shares the load of the wind wheels, reduces the wear rate of a single wind wheel, and extends the service life of the air supply fan 220.

[0145] Moreover, by installing multiple wind wheels on the same drive shaft, the system can handle a larger air flow. This design increases the total air volume output capacity of the fan and improves the air flow efficiency; the design of setting the drive motor between the wind wheels makes the system structure more compact and saves space; in addition, by controlling the operating state of the drive motor, the rotation speed of multiple wind wheels can be adjusted at the same time, so as to flexibly adjust the air volume to meet different needs.

[0146] In one feasible embodiment, the number of wind wheels includes two, the drive motor is located between the two wind wheels, both ends of the drive shaft pass through the drive motor respectively and are connected to the centers of the two wind wheels; the drive motor is configured to drive the two wind wheels to rotate simultaneously.

[0147] The driving motor provided in this embodiment is located between the two wind wheels to provide rotational power. Specifically, the driving motor transmits power to the two wind wheels through the driving shaft; when the driving shaft rotates, the two wind wheels rotate simultaneously to drive the air flow.

[0148] In this way, two wind wheels are driven simultaneously by one driving motor. On the one hand, energy transfer is more direct and efficient, the loss of intermediate transmission components is reduced, and the utilization efficiency of the air supply fan 220 is improved; on the other hand, it helps to ensure the synchronous movement of the two wind wheels, avoiding the problem of uneven air flow caused by inconsistent operation of multiple driving motors; on the other hand, placing the driving motor between the two wind wheels makes the system structure more compact and saves space; on the other hand, the synchronous rotation of the two wind wheels helps to balance the mechanical load, reduce the vibration and noise of the system, and improve the smoothness and comfort of operation.

[0149] In one possible implementation, referring to Figure 4 and Figure 5 As shown, an electric control box 500 is also included, wherein a circuit board is generally installed in the electric control box 500, and the range hood unit and the air conditioning unit inside the kitchen air conditioner are controlled by the circuit board.

[0150] In the embodiment of the present application, the electric control box 500 is located below the air supply fan 220 along the height direction of the housing 100. In this way, condensed water can be effectively prevented from dripping directly onto the electric control box 500, reducing the risk of the electric control box 500 contacting condensed water, and improving the safety and reliability of the electric control box 500.

[0151] In the embodiment of the present application, the electric control box 500 is opposite to the air outlet end of the air duct 260 , so that the airflow blown out from the air outlet end of the air duct 260 is diverted to the surface of the electric control box 500 .

[0152] With such a design, since the electric control box 500 usually includes a circuit board and a control circuit, these components will generate heat when working. By utilizing the airflow generated by the air supply fan 220 and guiding the airflow to the surface of the electric control box 500, the system can effectively dissipate heat, prevent the circuit board and the control circuit from overheating, and improve the reliability and service life of the electric control box 500.

[0153] In one possible implementation, referring to Figures 6 to 8 As shown, a water tank 320 is also included. In the horizontal direction, the electric control box 500 and the water tank 320 are arranged side by side, and the water tank 320 is located on the side of the electric control box 500; wherein, the air outlet end of the air duct 260 is located above the water tank 320.

[0154] In the embodiment of the present application, the side-by-side arrangement design can make full use of the space inside the kitchen air conditioner, help maximize the function within a limited space, and also make it easier for maintenance personnel to access and repair the electrical control box 500.

[0155] In addition, the air outlet end of the air duct 260 is located above the water tank 320, which not only provides heat dissipation for the electrical control box 500, but also promotes the evaporation or temperature regulation of water in the water tank 320 through the airflow located above the water tank 320. In addition, the airflow can pass through the surface of the water tank 320 to help take away the heat around the water tank 320. This multifunctional design that utilizes airflow improves the overall efficiency of the system.

[0156] In one possible implementation, referring to Figure 4 As shown, it also includes a water guide pipe 330. The bottom surface of the water receiving tray 310 is provided with a water outlet. The water tank 320 and the water outlet of the water receiving tray 310 are connected through the water guide pipe 330. The water guide pipe 330 is configured to guide the condensed water in the water receiving tray 310 to the water tank 320.

[0157] In the embodiment of the present application, the material, shape and size of the water diversion pipe 330 are not limited. For example, the water diversion pipe 330 can be made of plastic material, which has the advantages of light weight, corrosion resistance, low cost, and easy processing and installation; or the water diversion pipe 330 can be made of rubber or silicone material, which has the advantages of good flexibility and high and low temperature resistance. This embodiment does not limit this.

[0158] In this way, the setting of the water pipe 330 provides greater design flexibility and can be adjusted according to the specific needs of the kitchen air-conditioning system to adapt to different installation environments and structural requirements; at the same time, the condensed water in the water tray 310 can flow smoothly into the water tank 320. This design ensures the efficient collection and discharge of condensed water and reduces the risk of water overflow or accumulation.

[0159] Among them, in the height direction of the housing 100, the water outlet is located at the lowest position of the bottom surface of the water receiving tray 310. In this way, the condensed water can quickly flow to the water outlet, which minimizes the retention of the condensed water in the water receiving tray 310 and improves the discharge efficiency of the condensed water.

[0160] In one possible implementation, referring to Figure 7 and Figure 8 As shown, a drain pipe 600 and a drain pump 700 may also be included. The top of the shell 100 is provided with an opening of the shell 100; the drain pipe 600 has a drain interface 610, and the drain pipe 600 is connected to the drain pump 700 through the drain interface 610. The outlet of the drain pipe 600 is connected to the shell 100, and the drain pump 700 is configured to drive the condensed water in the water tank 320 to be transported to the opening of the shell 100 through the drain pipe 600.

[0161] In the embodiment of the present application, the drain pump 700 is generally made of corrosion-resistant plastic or metal to resist the corrosion of condensed water. The drain pump 700 drives the impeller to rotate through the motor, and uses centrifugal force to effectively transport the condensed water from the water tank 320 to the housing opening 131.

[0162] In this way, the introduction of the drain pump 700 significantly improves the discharge capacity of condensed water and ensures the efficient operation of the system; in addition, there is no limitation on the installation position of the drain pump 700. For example, the drain pump 700 can be set in the water tank 320 to avoid occupying the space of the water receiving pan 310, thereby utilizing the limited internal space to achieve the integration of complex functions, optimize the internal space layout of the air conditioner, and make the overall structure more compact.

[0163] In the embodiment of the present application, the drain pipe 600 can be designed as a straight pipe; or, it can be designed as a pipe with appropriate bends. This embodiment does not limit this and can be designed specifically according to actual installation requirements.

[0164] In this way, the design of the drain pipe 600 reduces the risk of leakage when condensed water flows between different components, provides additional protection and guidance, reduces the possibility of water overflow within the system, and at the same time helps to optimize the spatial layout inside the air conditioner, making the overall structure more compact and avoiding unnecessary space occupation.

[0165] The kitchen air conditioner provided by the present application comprises an evaporator assembly, a water tray and an air supply fan, and the cold air flow channel comprises a vertically penetrating air channel, and the air channel is located on the same side of the water tray and the evaporator assembly in the circumferential direction. In this way, the airflow can be smoothly guided to the air inlet end of the air supply fan after cooling down through the evaporator assembly, reducing the resistance and vortex phenomenon of the airflow, improving the efficiency of air flow, thereby maximizing the cold air intake efficiency of the air supply fan and improving the cooling effect.
