[0043] Combined with Figures 1-8 As shown, the embodiments of the present disclosure provide a kitchen air conditioner, including a housing 100 and a heat exchange component. As Figure 1As shown, the interior of the housing 100 is divided into a first area 110 and a second area 120 by a partition 121, and the first area 110 is located in front of the second area 120; wherein the first area 110 is divided into a first chamber 111 and a second chamber 112 by a first water receiving tray 200, and the first chamber 111 is located above the second chamber 112; wherein the first water receiving tray 200 is provided with a vent 201, the first chamber 111 is provided with an air outlet 102, and the second chamber 112 is provided with an air inlet 101; the heat exchange assembly includes an evaporator 130 and a condenser 140, wherein the evaporator 130 is arranged in the first chamber 111 and located above the first water receiving tray 200, and the condenser 140 is arranged in the second area 120.

[0044] In this embodiment, the interior of the housing 100 is divided into a first area 110 and a second area 120 in front and back by a partition 121, and the first area 110 is further divided into a first chamber 111 and a second chamber 112 in upper and lower parts by a first water receiving tray 200. In addition, the evaporator 130 and the condenser 140 are respectively arranged in the first area 110 and the second area 120. Since the first area 110 and the second area 120 are not intercommunication, the heat of the evaporator 130 and the condenser 140 can be prevented from affecting each other. Indoor air enters the second chamber 112 from the air inlet 101, then enters the first chamber 111 from the vent 201, and then blows back into the room from the air outlet 102 after heat exchange with the evaporator 130.

[0045] Optionally, the air inlet 101 is provided with an air inlet grille, so that foreign matter can be prevented from entering the second chamber 112 through the air inlet grille.

[0046] Alternatively, if Figure 2 As shown, the evaporator 130 is a finned heat exchanger.

[0047] In this embodiment, the evaporator 130 is tiltedly arranged in the first chamber 111 and supported by the first water receiving tray 200, and the tilted surface of the evaporator 130 corresponds to the vent 201. The first water receiving tray 200 is used to receive the condensed water of the evaporator 130. In this way, the evaporator 130 can be arranged with a larger heat exchange area, and the air can be directly blown to the evaporator 130, thereby improving the evaporation efficiency.

[0048] Alternatively, if Figure 2 As shown, the condenser 140 is a double-tube heat exchanger.

[0049] In this embodiment, the shell-and-tube heat exchanger includes an inner tube and an outer tube, wherein the inner tube is sleeved inside the outer tube and a fluid channel is formed between the inner tube and the outer tube. The fluid channel is connected to the refrigerant circulation system of the kitchen air conditioner, and the inner tube is connected to an external water source as cooling water. In this way, the cooling water and the refrigerant are used for water-cooling heat exchange to realize the condensation function of the shell-and-tube heat exchanger.

[0050] Optionally, the kitchen air conditioner further includes a supply air fan 131, which is disposed in the second chamber 112, and the fan outlet thereof communicates with the ventilation opening 201. In this way, when the supply air fan 131 is started, indoor air enters the second chamber 112 from the air inlet 101, is blown from the fan outlet of the supply air fan 131 to the communication opening, and then enters the first chamber 111.

[0051] Optionally, the supply air fan 131 is a centrifugal fan.

[0052] In this embodiment, the axis of the centrifugal fan is horizontally arranged, and the centrifugal fan is fixed in the second chamber 112 through a fan bracket. The fan motor of the centrifugal fan is disposed in the middle of the volute, and air enters from both sides of the volute when the centrifugal fan rotates.

[0053] Optionally, as Figure 1 and Figure 2 shown, the air outlet air conditioner further includes a filter module 160. A filter socket 161 is provided above the air inlet 101. The filter module 160 is inserted into the second chamber 112 through the filter socket 161 and is located between the supply air fan 131 and the air inlet 101. In this way, the filter module 160 can be installed through the filter socket 161 without disassembling the casing 100, and the operation is simple and easy to replace.

[0054] Optionally, the filter module 160 is fixed in the second chamber 112 by a magnetic attraction structure.

[0055] In this embodiment, the filter module 160 includes a filter body and a filter frame, and the filter body is installed in the filter frame. A filter bracket is provided in the second chamber 112. After the filter module 160 extends into the second chamber 112 from the filter socket 161, the filter frame is supported by the filter bracket. Moreover, magnetic attraction structures are provided on both sides or around the filter frame, and the filter frame is magnetically attracted to the filter bracket.

[0056] Optionally, the casing 100 includes a front panel, and the front panel is located on the front side of the first region 110; the kitchen air conditioner further includes an electric control box 170, and the electric control box 170 is disposed in the first region 110 and abuts against the front panel.

[0057] In this embodiment, the front panel is located on the front side of the casing 100, and both the air inlet 101 and the air outlet 102 are opened on the front panel. Since the electric control box 170 is disposed adjacent to the front panel, the electric control box 170 can be exposed after the front panel is removed, thus facilitating the maintenance of the electric control box 170.

[0058] Optionally, the kitchen air conditioner further includes a compressor 150, and the compressor 150 is disposed in the second region 120. A compressor bracket is provided in the second region 120, and the compressor 150 is installed on the compressor bracket.

[0059] In some embodiments, the kitchen air conditioner includes a housing 100 and a wind deflector assembly. The interior of the housing 100 includes a first area 110, and the first area 110 is separated by a first water receiving tray 200 into a first chamber 111 and a second chamber 112; wherein, the first water receiving tray 200 is provided with a ventilation opening 201, the first chamber 111 is provided with an air outlet 102, and the second chamber 112 is provided with an air inlet 101; the wind deflector assembly is disposed within the housing 100 and includes a wind deflector 300; the wind deflector 300 is movably disposed at the ventilation opening 201 to block or avoid the ventilation opening 201.

[0060] In this embodiment, the first water receiving tray 200 serves to separate the first area 110 and is provided with a ventilation opening 201 to connect the first chamber 111 and the second chamber 112. Outdoor air enters the second chamber 112 through the air inlet 101, then enters the first chamber 111 through the ventilation opening 201, and finally blows into the room through the air outlet 102. Moreover, the ventilation opening 201 can be blocked by the wind deflector 300, thereby adjusting the air volume of the ventilation opening 201, so that the air volume of the air outlet 102 can be adjusted without adjusting the angle of the air deflector at the air outlet 102.

[0061] Optionally, the wind deflector 300 moves along a horizontal plane.

[0062] Optionally, as Figure 3 and Figure 4 shown, the first chamber 111 is located above the second chamber 112, the ventilation opening 201 extends downward to form a wind guiding enclosure 210, and the wind guiding enclosure 210 is provided with an avoidance opening 211; the wind deflector 300 is disposed on one side of the wind guiding enclosure 210 and corresponds to the avoidance opening 211; the wind deflector 300 can extend into the wind guiding enclosure 210 through the avoidance opening 211 to block the ventilation opening 201.

[0063] In this embodiment, the wind guiding enclosure 210 extends into the second chamber 112, and its avoidance opening 211 is adapted to the wind deflector 300, so that the wind deflector 300 can smoothly extend into the wind guiding enclosure 210 through the avoidance opening 211, and it can also reduce the leakage of air in the wind guiding enclosure 210 from the avoidance opening 211.

[0064] Optionally, when the wind deflector 300 completely avoids the ventilation opening 201, the end of the wind deflector 300 facing the ventilation opening 201 is located within the avoidance opening 211. In this way, it can prevent air from leaking from the avoidance opening 211, and the avoidance opening 211 can always support the wind deflector 300.

[0065] Optionally, the air supply fan 131 is disposed in the second chamber 112, and its fan outlet is connected to the wind guiding enclosure 210 to supply air to the ventilation opening 201 through the wind guiding enclosure 210.

[0066] In this embodiment, asFigure 2 As shown, a fixed flange is provided at the lower end of the air guiding enclosure 210, and a mounting flange is provided at the fan outlet of the air supply fan 131. A bolt fastener can be used to assemble the mounting flange onto the fixed flange. When the air supply fan 131 is started, the air in the second chamber 112 enters the air guiding enclosure 210 from the fan outlet, and then supplies air to the ventilation opening 201.

[0067] Optionally, the wind shielding assembly further includes a first driving assembly for driving the wind shielding plate 300 to move.

[0068] Optionally, as Figure 5 and Figure 6 shown, the first driving assembly includes a first rack 340 and a first motor 342. Among them, the first rack 340 is provided on the wind shielding plate 300 and is arranged along the moving direction of the wind shielding plate 300; the first driving gear 341 of the first motor 342 meshes with the first rack 340 to drive the first rack 340 to move. In this way, the wind shielding plate 300 is driven to move horizontally through the gear-rack structure.

[0069] Exemplarily, when it is necessary to block the ventilation opening 201, the first motor 342 rotates forward, the first driving gear 341 rotates and drives the first rack 340 to move towards the ventilation opening 201. At this time, the first rack 340 drives the wind shielding plate 300 to gradually extend into the air guiding enclosure 210 from the avoidance opening 211, so as to block the ventilation opening 201. After that, when it is necessary to avoid the ventilation opening 201, the first motor 342 rotates in reverse, the first driving gear 341 rotates and drives the first rack 340 to move in the reverse direction. At this time, the first rack 340 drives the wind shielding plate 300 to gradually move out of the ventilation opening 201 from the avoidance opening 211, so as to avoid the ventilation opening 201.

[0070] Optionally, as Figure 6 shown, the first rack 340 is provided on the lower plate surface 321 of the wind shielding plate 300; a mounting plate is provided on the lower plate surface 321 of the first water receiving tray 200, the first motor 342 is fixed on the mounting plate, and the first driving gear 341 is supported below the first rack 340. In this way, the mounting plate is located on one side of the wind shielding plate 300, the first motor 342 is mounted on the mounting plate, and the first driving gear 341 meshes with and supports the first rack 340.

[0071] Optionally, a slide rail is further provided on the lower disk surface of the first water receiving tray 200, and the slide rail is arranged along the moving direction of the wind shielding plate 300; a chute is provided on the upper plate surface 311 of the wind shielding plate 300, and the chute is adapted to the slide rail so that the wind shielding plate 300 moves along the slide rail through the chute.

[0072] In this embodiment, the sliding groove and the sliding rail form a sliding connection. When the first rack 340 drives the windshield 300 to move, the sliding groove slides along the sliding rail. In this way, the sliding rail plays a role in limiting and guiding the movement of the windshield 300, making the movement of the windshield 300 smoother.

[0073] Optionally, as Figure 6 and Figure 7 shown, the windshield 300 is configured as a multi-layer structure, including an upper plate surface 311, an intermediate plate surface 323, and a lower plate surface 321. The upper plate surface 311 and the lower plate surface 321 enclose a hollow box body, and the intermediate plate surface 323 is movably disposed inside the box body. Wherein, the front end of the box body faces the ventilation opening 201, a moving opening 330 is provided at the rear end of the box body, and the intermediate plate surface 323 can move out of the box body through the moving opening 330. And, a first filter screen 310 is provided on the upper plate surface 311, and a second filter screen 320 is provided on the lower plate surface 321. When the windshield 300 completely or partially blocks the ventilation opening 201, the intermediate plate surface 323 is moved out of the box body. At this time, the air in the second chamber 112 will flow through the ventilation opening 201 in sequence through the second filter screen 320, the inside of the box body, and the first filter screen 310. Preferably, both the first filter screen 310 and the second filter screen 320 are high-efficiency filter screens that can filter oil stains. In this way, when the intermediate plate surface 323 is located inside the box body, the windshield 300 plays a role in blocking the ventilation opening 201; when the intermediate plate surface 323 is partially or completely moved out of the box body, the windshield 300 plays a filtering role.

[0074] Optionally, the windshield assembly further includes a second driving component for driving the intermediate plate surface 323 to move.

[0075] Optionally, as Figure 5 and Figure 6 shown, the second driving component further includes a second rack 350 and a second motor 352. The second rack 350 is disposed on the intermediate plate surface 323 and is arranged along the moving direction of the intermediate plate surface 323. The second driving gear 351 of the second motor 352 meshes with the second rack 350 for driving the second rack 350 to move. In this way, the intermediate plate surface 323 is driven to partially or completely move out of the box body through the gear-rack structure. Here, after completely moving out of the box body, the front end of the intermediate plate surface 323 is still located at the moving opening 330.

[0076] Optionally, the second rack 350 is disposed in the middle of the intermediate plate surface 323 and faces the lower plate surface 321. The lower plate surface 321 is provided with a through rack groove 331, and the second rack 350 is located inside the rack groove 331 or extends downward out of the rack groove 331. The second motor 352 is disposed on the side surface of the air guide enclosure 210 and below the lower plate surface 321, and its drive shaft meshes with the second rack 350.

[0077] Optionally, both the avoidance opening 211 and the moving opening 330 are provided with notches to avoid the moving first rack 340 and second rack 350.

[0078] Optionally, the length of the first rack 340 is arranged according to the moving distance of the wind deflector 300, and the length of the second rack 350 is arranged according to the moving distance of the intermediate plate surface 323. The positions of the first motor 342 and the second motor 352 are arranged according to the actual space of the second compartment 112.

[0079] Exemplarily, when it is necessary to block the ventilation opening 201, the first motor 342 and the second motor 352 rotate forward synchronously. The first driving gear 341 rotates and drives the first rack 340 to move towards the ventilation opening 201. At this time, the first rack 340 drives the wind deflector 300 to gradually extend from the avoidance opening 211 into the air guide enclosure 210. The second rack 350 rotates forward synchronously to ensure that the intermediate plate surface 323 is always completely located inside the box body, thereby blocking the ventilation opening 201. When there is a filtering requirement at the same time, the second motor 352 rotates in reverse. The second driving gear 351 rotates and drives the second rack 350 to move in the reverse direction. At this time, the second rack 350 drives the intermediate plate surface 323 to gradually move out of the box body from the moving opening 330, so as to use the first filter screen 310 and the second filter screen 320 for filtering. As Figure 7 shown, when a part of the intermediate plate surface 323 moves out of the box body, part of the ventilation opening 201 can be blocked, and the air of the ventilation opening 201 can be filtered. In this way, multiple requirements of users can be met.

[0080] The embodiment of the present disclosure also provides an air conditioner thawing table combined system, including a kitchen air conditioner and a thawing table. Among them, the kitchen air conditioner includes a condenser 140, and the condenser 140 is a shell-and-tube heat exchanger; the condenser 140 includes an inner tube and an outer tube, and the inner tube is sleeved in the outer tube and a fluid channel is formed between the inner tube and the outer tube; wherein, the inner tube is used to connect to an external water source as cooling water, and the fluid channel is used to connect to a refrigerant; the thawing table includes a hot water pipe, and the water inlet end of the hot water pipe is connected to the water outlet end of the inner tube through a first solenoid valve, and the water outlet end of the hot water pipe is connected to the water inlet end of the inner tube through a second solenoid valve. Here, the kitchen air conditioner includes the kitchen air conditioner described in any of the above embodiments.

[0081] In this embodiment, low-temperature cooling water is injected from the water inlet end of the inner tube, and then exchanges heat with the high-temperature refrigerant in the fluid channel. After the cooling water exchanges heat, its temperature rises, and high-temperature cooling water flows out from the water outlet end of the inner tube. When the first solenoid valve is opened, the high-temperature cooling water enters the hot water pipe. At this time, the hot water pipe flows into the thawing table to play a role in thawing items. The cooling water exchanges heat with the items to be thawed in the hot water pipe and then its temperature decreases. When the second solenoid valve is opened, the low-temperature cooling water returns to the inner tube and exchanges heat with the high-temperature refrigerant in the fluid channel again. In this way, the kitchen air conditioner is combined with the thawing table, and the recovery and utilization of the condensation heat is realized by using the circulation of the cooling water.

[0082] Optionally, the air conditioner defrosting table combined system further includes a water collecting tank, and the water in the water collecting tank serves as cooling water. The water inlet end of the inner pipe communicates with the water outlet of the water collecting tank, and the water outlet end communicates with the water return port of the water collecting tank through a fifth electromagnetic valve. A temperature sensor is provided at the water outlet end of the inner pipe. When the defrosting table is working and the temperature at the water outlet end of the inner pipe reaches the defrosting temperature, the first electromagnetic valve is opened. A temperature sensor is provided at the water outlet end of the hot water pipe. When the temperature at the water outlet end of the hot water pipe reaches the cooling temperature, the second electromagnetic valve is opened. When the defrosting table is not working, the fifth electromagnetic valve is opened to discharge the high-temperature cooling water to the water collecting tank, and the cooling water cools down in the water collecting tank and then flows from the water outlet to the inner pipe.

[0083] Optionally, the kitchen air conditioner further includes an evaporator 130, and a first water receiving tray 200 is provided below the evaporator 130; a second water receiving tray 220 is provided below the condenser 140 and part of the condenser 140 is located in the second water receiving tray 220, and the first water receiving tray 200 communicates with the second water receiving tray 220 through a condensate pipe 221.

[0084] In this embodiment, the low-temperature condensate generated on the evaporator 130 flows into the first water receiving tray 200, and then the low-temperature condensate flows into the second water receiving tray 220 through the condensate pipe 221. Since the lower part of the condenser 140 is located in the second water receiving tray 220, the low-temperature condensate can be used to exchange heat with the high-temperature refrigerant in the fluid channel, thereby improving the condensation effect.

[0085] Optionally, a drain pump 230 is provided in the second water receiving tray 220, and the drain pump 230 has a first drain pipeline, and the first drain pipeline communicates with the water inlet end of the hot water pipe through a third electromagnetic valve.

[0086] In this embodiment, the temperature of the condensate rises after exchanging heat with the high-temperature refrigerant. When the third electromagnetic valve is opened, the high-temperature condensate enters the hot water pipe. In this way, both the high-temperature cooling water and the high-temperature condensate can flow into the hot water pipe to thaw items.

[0087] Optionally, the drain pump 230 is configured to drain water through the first drain pipeline when the defrosting table is working and the temperature of the condensate is greater than or equal to the defrosting temperature. When the temperature of the condensate is less than the defrosting temperature, the kitchen air conditioner is controlled to reduce the air volume.

[0088] In this embodiment, a temperature sensor is provided in the second water receiving tray 220. When the temperature of the condensate is greater than or equal to the defrosting temperature, the third electromagnetic valve is opened, and the drain pump 230 discharges the high-temperature condensate into the hot water pipe through the first pipeline. When the temperature of the condensate is less than the defrosting temperature, the third electromagnetic valve is not opened temporarily, and the collection rate of the low-temperature condensate in the second water receiving tray 220 slows down after the kitchen air conditioner reduces the air volume, which is beneficial to the rapid increase of the temperature of the condensate in the second water receiving tray 220 to be greater than or equal to the defrosting temperature.

[0089] In this embodiment, since the air in the kitchen scenario contains more oil fumes, when the air exchanges heat with the evaporator 130, the condensed water will contain oil stains. Due to the relatively thin and dense diameter of the heating pipe, during the flow of the condensed water through the heating pipe, the oil stains are extremely likely to adhere to the inner wall of the heating pipe, thereby affecting the thawing effect. At this time, when controlling the kitchen air conditioner to reduce the air volume, the above-mentioned wind deflector 300 can simultaneously play the role of reducing the air volume and filtering the oil stains.

[0090] Exemplarily, first, control the first motor 342 and the second motor 352 to rotate forward synchronously. Drive the wind deflector 300 to completely block the ventilation opening 201 through the corresponding gear-rack structure, and ensure that the middle plate surface 323 is always entirely located inside the box. Then control the second motor 352 to reverse, and drive the middle plate surface 323 to partially move out of the box through the corresponding gear-rack structure. In this way, the first filter screen 310 and the second filter screen 320 that are not blocked by the middle plate surface 323 can filter the oil stains, and the middle plate surface 323 that does not move out of the box can play the role of reducing the air volume.

[0091] Optionally, the drain pump 230 further has a second drain pipe, and the second drain pipe is connected to the external environment through a fourth solenoid valve. In this way, when the fourth solenoid valve is opened, the condensed water can be directly discharged to the external environment through the second drain pipe.

[0092] Optionally, the drain pump 230 is configured to drain water through the second drain pipe when the water level of the condensed water is greater than the drain water level. In this way, it is possible to avoid the overflow of the condensed water.

[0093] Optionally, the drain pump 230 is configured to drain water through the second drain pipe when the temperature of the condensed water is greater than or equal to the temperature of the cooling water at the water outlet end of the inner pipe.

[0094] In this embodiment, when the temperature of the condensed water is greater than or equal to the temperature of the cooling water at the water outlet end of the inner pipe, the relatively high temperature of the condensed water is not conducive to the condensation of the condenser 140. At this time, if the thawing table does not need to work, the condensed water is directly discharged to the external environment.

[0095] Optionally, when the defrosting table is working and the condensed water is discharged into the heating pipe, first, all the existing condensed water in the second water receiving tray 220 is discharged to the external environment, and here, a drain pump 230 is used to drain water through the second drain pipeline. Then, a baffle is used to completely block the ventilation opening 201, and at the same time, the middle plate surface 323 is completely moved out of the box body. Here, a first motor 342 is used to drive the baffle to move, and a second motor 352 is used to drive the middle plate surface 323 to move. In this way, relatively clean condensed water accumulates again and quickly in the second water receiving tray 220. Then, when the condensed water accumulates to the defrosting water level and the temperature of the condensed water is greater than or equal to the defrosting temperature, the condensed water is discharged into the heating pipe, and here, a drain pump 230 is used to drain water through the first pipeline. When the condensed water accumulates to the first defrosting water level but the temperature of the condensed water is still less than the defrosting temperature, the middle plate surface 323 is partially moved into the box body to partially block the ventilation opening 201. In this way, the accumulation rate of the low-temperature condensed water is slowed down so that the temperature of the condensed water rises rapidly. When the temperature of the condensed water gradually rises to be greater than or equal to the defrosting temperature, the condensed water is then discharged into the heating pipe. Here, the defrosting water level is lower than the drainage water level. If the temperature is still less than the defrosting temperature when the water level is higher than the drainage water level, only the part of the condensed water higher than the drainage water level is discharged through the second drain pipeline.

[0096] Optionally, a rotatable air deflector 400 is provided at the air outlet, and a rotatable air guiding plate 410 is provided in the first compartment. The air guiding plate 410 is used to guide air to the air deflector 400 so as to form a converging air guide at the air outlet.

[0097] In this embodiment, the air guiding plate 410 adjusts the air volume by changing the ventilation cross-section of the air outlet duct 420 through rotation. Exemplarily, an air outlet duct 420 is provided in the first compartment 111, and the air outlet duct 420 is configured as an arc surface. The first end of the air outlet duct 420 faces the air outlet 102, and the second end faces the evaporator 130. The air guiding plate 410 is configured as an arc surface, and the air guiding plate 410 has the same curvature as the air outlet duct 420. As Figure 8 shown by the dotted line in the figure, when the air guiding plate 410 rotates to be parallel to the air outlet duct 420, the air volume of the air outlet duct 420 is the largest; when either end of the air guiding plate 410 rotates towards the inner wall of the air outlet duct 420, the ventilation cross-section of the air outlet duct 420 decreases, and thus the air volume decreases. Here, both the air deflector 400 and the air guiding plate 410 are driven to rotate by motors. In this way, the air flows to the air deflector 400 after being guided by the air guiding plate 410, thereby forming a converging air guide form in which the air deflector 400 adjusts the air direction of the air outlet 102 and the air guiding plate 410 adjusts the air volume of the air outlet 102.

[0098] Optionally, as Figure 9 shown, the present disclosure embodiment also provides a method for controlling a kitchen air conditioner, including:

[0099] S10: The processor determines the uncomfortable parts of the human body according to the user's thermophysiological model;

[0100] S20: The processor adjusts the air guiding parameters of the aggregated air guiding according to the uncomfortable parts.

[0101] In this embodiment, preferably, the human body is divided into six parts: head, chest, abdomen, back, hand, and leg. The thermophysiological model can at least reflect the temperatures of these six parts. When the temperature of a certain part is outside the suitable temperature range, it is determined by the processor as an uncomfortable part. Here, the air guiding parameters refer to the wind direction and air volume of the air outlet. In this way, the form of aggregated air guiding is formed by using the diversion plate and the air guiding plate, and the uncomfortable parts of the user are determined according to the user's thermophysiological model, and then the air guiding parameters are adjusted according to the uncomfortable parts, so as to quickly eliminate the discomfort of the uncomfortable parts of the user.

[0102] Optionally, as Figure 10 shown, step S10, determining the uncomfortable parts of the human body according to the user's thermophysiological model, includes:

[0103] S11: The processor obtains the user's thermophysiological model;

[0104] S12: The processor compares the thermophysiological model with the comfort model to determine the uncomfortable parts of the human body.

[0105] In this embodiment, the kitchen air conditioner is equipped with an infrared thermal imager, and the processor obtains the user's thermophysiological model through the infrared thermal imager. The thermophysiological model includes the actual temperature of the head, the actual temperature of the chest, the actual temperature of the abdomen, the actual temperature of the back, the actual temperature of the hand, and the actual temperature of the leg. The comfort model includes the comfortable temperature range of the head, the comfortable temperature range of the chest, the comfortable temperature range of the abdomen, the comfortable temperature range of the back, the comfortable temperature range of the hand, and the comfortable temperature range of the leg. Suppose the processor finds through comparison that the actual temperature of the head is greater than the upper limit of the comfortable temperature range of the head, then it is determined that the head is the uncomfortable part of the human body.

[0106] In this embodiment, the comfort model is stored in the processor, and the comfort model is divided into a children's comfort model, an adult comfort model, and an elderly comfort model according to the population. The processor obtains the user's image through the camera, confirms the population to which the user belongs through image recognition, and finally compares the thermophysiological model with the corresponding comfort model. For example, if the user is identified as an elderly person, the processor compares the thermophysiological model with the elderly comfort model.

[0107] Optionally, step S20, adjusting the air guiding parameters of the aggregated air guiding according to the uncomfortable parts, includes:

[0108] Controlling the angle of the air guiding plate to adjust the wind direction of the air outlet to face the uncomfortable part.

[0109] In this embodiment, while the processor obtains the user's thermal physiological model through an infrared thermal imager, it also obtains the actual positions of the user's six major body parts. Assuming that the processor determines that the head is the uncomfortable part of the human body, the processor controls the air deflector to rotate so that the air direction faces the head. If the actual temperature of the head is relatively high, the kitchen air conditioner operates in a cooling mode, and then blows cold air towards the user's head.

[0110] Optionally, step S20, adjusting the air guiding parameters of the aggregated air guiding according to the uncomfortable part, further includes:

[0111] Controlling the angle of the drainage plate according to the user's distance to adjust the air volume at the air outlet.

[0112] In this embodiment, while the processor obtains the user's thermal physiological model through an infrared thermal imager, it also obtains the distance between the user and the kitchen air conditioner. When the user's distance is greater than the comfortable distance, the air volume at the air outlet is increased; when the user's distance is less than the comfortable distance, the air volume at the air outlet is decreased. Assuming that the processor controls the air deflector to blow air towards the user's head, if the user approaches the kitchen air conditioner during cooking, causing the user's distance to be less than the comfortable distance, the processor controls the drainage plate to rotate to reduce the air volume at the air outlet.

[0113] Optionally, the interior of the casing includes a first area, and the first area is divided into a first compartment and a second compartment by a first water receiving tray. The air outlet and the drainage plate are arranged in the first compartment; wherein, the first water receiving tray is provided with a ventilation opening, and the second compartment is provided with an air inlet; the kitchen air conditioner further includes a filtering device, and the filtering device is movably arranged at the ventilation opening. When the filtering device moves to the ventilation opening, it can filter the flowing air; when the filtering device moves out of the ventilation opening, it does not play a filtering role.

[0114] Optionally, as Figure 11 shown, this embodiment of the present disclosure also provides another method for controlling a kitchen air conditioner, including:

[0115] S10: The processor determines the uncomfortable part of the human body according to the user's thermal physiological model;

[0116] S20: The processor adjusts the air guiding parameters of the aggregated air guiding according to the uncomfortable part;

[0117] S30: The processor adjusts the position of the filtering device according to the uncomfortable part.

[0118] In this embodiment, the sequence of steps S20 and S30 is not limited and they can be executed synchronously. Step S30 includes: when the uncomfortable part is determined to be the head, controlling the filter device to move to the ventilation opening. Since the air in the kitchen scenario contains a lot of lampblack, during the process of blowing air to the head, a large amount of oil stains will quickly adhere to the user's face. At this time, the processor controls the filter device to move to the ventilation opening, and the filter device can be used to filter the oil stains, so that relatively clean air is blown to the head.

[0119] Optionally, the filter device includes a wind deflector, which is formed by an upper plate surface and a lower plate surface enclosing a hollow box body, and filter meshes are provided on both the upper plate surface and the lower plate surface. The middle plate surface is movably arranged in the box body.

[0120] In this embodiment, the filter device is the wind deflector described in the above embodiment. The first driving component is used to drive the wind deflector to move, and the second driving component is used to drive the middle plate surface to move. The specific structure will not be elaborated here. The processor controls the first motor to drive the wind deflector to extend into the air guide enclosure from the avoidance opening and completely block the ventilation opening. Then, the processor controls the second motor to drive the middle plate surface to partially or completely move out of the box body. In this way, filtering is carried out by using the first filter mesh and the second filter mesh. And when the distance of the user is less than the comfortable distance, the middle plate surface partially moves out of the box body, so that it can not only cooperate with the diversion plate to reduce the air volume at the air outlet, but also filter the flowing air.

[0121] The embodiment of the present disclosure also provides a device for controlling a kitchen air conditioner, including a processor and a memory storing program instructions. The processor is configured to execute the above method for controlling a kitchen air conditioner when running the program instructions.

[0122] The embodiment of the present disclosure also provides a kitchen air conditioner, including the above device for controlling a kitchen air conditioner.
