[0048] Combined with Figure 1-7 As shown, the embodiments of the present disclosure provide a kitchen air conditioner, including a housing 100 and a heat exchange component. As Figure 1 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 compartment 111 and a second compartment 112 by a first water receiving tray 200, and the first compartment 111 is located above the second compartment 112; wherein, the first water receiving tray 200 is provided with a ventilation opening 201, the first compartment 111 is provided with an air outlet 102, and the second compartment 112 is provided with an air inlet 101; the heat exchange component includes an evaporator 130 and a condenser 140, wherein the evaporator 130 is disposed in the first compartment 111 and above the first water receiving tray 200, and the condenser 140 is disposed in the second area 120.

[0049] In this embodiment, the interior of the housing 100 is divided into a front and rear first area 110 and a second area 120 by a partition 121, and the first area 110 is further divided into an upper and lower first compartment 111 and a second compartment 112 by a first water receiving tray 200. Moreover, the evaporator 130 and the condenser 140 are respectively disposed in the first area 110 and the second area 120. Since the first area 110 and the second area 120 do not communicate with each other, the heat of the evaporator 130 and the condenser 140 can be prevented from affecting each other. Indoor air enters the second compartment 112 from the air inlet 101, then enters the first compartment 111 from the ventilation opening 201, and then blows back into the room from the air outlet 102 after exchanging heat with the evaporator 130.

[0050] Optionally, the air inlet 101 is provided with an air inlet grille. In this way, foreign objects can be blocked from entering the second compartment 112 through the air inlet grille.

[0051] Optionally, as Figure 2 shown, the evaporator 130 is a finned heat exchanger.

[0052] In this embodiment, the evaporator 130 is inclined and disposed in the first compartment 111 and is supported by the first water receiving tray 200, and the inclined surface of the evaporator 130 corresponds to the ventilation opening 201. The first water receiving tray 200 is used to receive the condensed water of the evaporator 130. In this way, a larger heat exchange area can be arranged for the evaporator 130, and the air can directly blow on the evaporator 130, thereby improving the evaporation efficiency.

[0053] Optionally, as Figure 2 shown, the condenser 140 is a shell-and-tube heat exchanger.

[0054] In this embodiment, the shell-and-tube heat exchanger includes an inner tube and an outer tube. The inner tube is sleeved inside the outer tube, and a fluid channel is formed between the inner tube and the outer tube. Among them, 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 shell-and-tube heat exchanger realizes its condensation function by using the cooling water to exchange heat with the refrigerant through water cooling.

[0055] Optionally, the kitchen air conditioner further includes a blower fan 131. The blower fan 131 is arranged in the second compartment 112, and its fan outlet is connected to the ventilation opening 201. In this way, when the blower fan 131 is started, the indoor air enters the second compartment 112 from the air inlet 101, is blown from the fan outlet of the blower fan 131 to the communication port, and then enters the first compartment 111.

[0056] Optionally, the blower fan 131 is a centrifugal fan.

[0057] In this embodiment, the axis of the centrifugal fan is horizontally arranged, and the centrifugal fan is fixed in the second compartment 112 through a fan bracket. The fan motor of the centrifugal fan is arranged in the middle of the volute, and when the centrifugal fan rotates, air enters from both sides of the volute.

[0058] 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 compartment 112 through the filter socket 161 and is located between the blower 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.

[0059] Optionally, the filter module 160 is fixed in the second compartment 112 by a magnetic structure.

[0060] In this embodiment, the filter module 160 includes a filter body and a filter frame. The filter body is installed inside the filter frame. A filter bracket is provided in the second compartment 112. After the filter module 160 extends into the second compartment 112 from the filter socket 161, the filter frame is supported by the filter bracket. Moreover, magnetic structures are provided on both sides or around the filter frame, and the filter frame is magnetically adsorbed on the filter bracket.

[0061] Optionally, the casing 100 includes a front panel, and the front panel is located on the front side of the first area 110; the kitchen air conditioner further includes an electric control box 170, and the electric control box 170 is arranged in the first area 110 and abuts against the front panel.

[0062] In this embodiment, the front panel is located on the front side of the cabinet 100, and both the air inlet 101 and the air outlet 102 are provided on the front panel. Since the electric control box 170 is disposed against the front panel, the electric control box 170 can be exposed after the front panel is removed, facilitating the maintenance of the electric control box 170.

[0063] Optionally, the kitchen air conditioner further includes a compressor 150, which is disposed in the second area 120. A compressor bracket is provided in the second area 120, and the compressor 150 is mounted on the compressor bracket.

[0064] In some embodiments, the kitchen air conditioner includes a cabinet 100 and a wind shielding assembly. The interior of the cabinet 100 includes a first area 110, and the first area 110 is separated by a first water receiving tray 200 into a first compartment 111 and a second compartment 112; wherein, the first water receiving tray 200 is provided with a ventilation opening 201, the first compartment 111 is provided with an air outlet 102, and the second compartment 112 is provided with an air inlet 101; the wind shielding assembly is disposed in the cabinet 100 and includes a wind shielding plate 300; the wind shielding plate 300 is movably disposed at the ventilation opening 201 to block or avoid the ventilation opening 201.

[0065] 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 compartment 111 and the second compartment 112. Outdoor air enters the second compartment 112 through the air inlet 101, then enters the first compartment 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 shielding plate 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.

[0066] Optionally, the wind shielding plate 300 moves along a horizontal plane.

[0067] Optionally, as Figure 3 and Figure 4 shown, the first compartment 111 is located above the second compartment 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 shielding plate 300 is disposed on one side of the wind guiding enclosure 210 and corresponds to the avoidance opening 211; the wind shielding plate 300 can extend into the wind guiding enclosure 210 through the avoidance opening 211 to block the ventilation opening 201.

[0068] In this embodiment, the wind guiding enclosure 210 extends into the second compartment 112, and its avoidance opening 211 is adapted to the wind shielding plate 300, facilitating the smooth extension of the wind shielding plate 300 into the wind guiding enclosure 210 through the avoidance opening 211, and also reducing the leakage of air in the wind guiding enclosure 210 from the avoidance opening 211.

[0069] Optionally, when the wind shield 300 completely avoids the vent 201, one end of the wind shield 300 facing the vent 201 is located in the avoidance opening 211. In this way, air leakage from the avoidance opening 211 can be avoided, and the avoidance opening 211 can always support the wind shield 300.

[0070] Optionally, the air supply fan 131 is disposed in the second chamber 112 , and a fan outlet thereof is connected to the air guide enclosure 210 , so as to supply air to the vent 201 through the air guide enclosure 210 .

[0071] In this embodiment, if Figure 2 As shown, a fixing flange is provided at the lower end of the air guide enclosure 210, and a mounting flange is provided at the fan outlet of the air supply fan 131. The mounting flange can be assembled on the fixing flange using bolt fasteners. When the air supply fan 131 is started, the air in the second chamber 112 enters the air guide enclosure 210 from the fan outlet, and then supplies air to the vent 201.

[0072] Optionally, the windshield assembly further includes a first driving assembly, and the first driving assembly is used to drive the windshield plate 300 to move.

[0073] Alternatively, if Figure 5 and Figure 6 As shown, the first driving assembly includes a first rack 340 and a first motor 342. The first rack 340 is provided on the windshield 300 and arranged along the moving direction of the windshield 300; the first driving gear 341 of the first motor 342 is engaged with the first rack 340, and is used to drive the first rack 340 to move. In this way, the windshield 300 is driven to move in the horizontal direction through the rack and gear structure.

[0074] For example, when the vent 201 needs to be blocked, the first motor 342 rotates forward, the first drive gear 341 rotates and drives the first rack 340 to move toward the vent 201. At this time, the first rack 340 drives the wind shield 300 to gradually extend from the avoidance opening 211 into the wind guide enclosure 210, thereby blocking the vent 201. Afterwards, when the vent 201 needs to be avoided, the first motor 342 rotates reversely, the first drive gear 341 rotates and drives the first rack 340 to move in the opposite direction, and at this time, the first rack 340 drives the wind shield 300 to gradually move out of the vent 201 from the avoidance opening 211, thereby avoiding the vent 201.

[0075] Alternatively, if Figure 6As shown, the first rack 340 is disposed on the lower plate surface 321 of the windshield 300; an installation plate is provided on the lower plate surface 321 of the first water receiving tray 200, the first motor 342 is fixed on the installation plate, and the first driving gear 341 is supported below the first rack 340. In this way, the installation plate is located on one side of the windshield 300, the first motor 342 is installed on the installation plate, and the first driving gear 341 meshes with and supports the first rack 340.

[0076] 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 windshield 300; a chute is provided on the upper plate surface 311 of the windshield 300, and the chute is adapted to the slide rail so that the windshield 300 moves along the slide rail through the chute.

[0077] In this embodiment, the chute and the slide rail form a sliding connection. When the first rack 340 drives the windshield 300 to move, the chute slides along the slide rail. In this way, the slide rail plays a role in limiting and guiding the movement of the windshield 300, making the movement of the windshield 300 smoother.

[0078] 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 in the box body. Among them, 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 in 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.

[0079] Optionally, the windshield assembly further includes a second driving assembly for driving the intermediate plate surface 323 to move.

[0080] Optionally, as Figure 5 and Figure 6As shown, the second driving component further includes a second rack 350 and a second motor 352. The second rack 350 is disposed on the middle plate surface 323 and is arranged along the moving direction of the middle plate surface 323. The second driving gear 351 of the second motor 352 meshes with the second rack 350 to drive the second rack 350 to move. In this way, the middle plate surface 323 is driven to partially or completely move out of the box body through the gear-rack structure. After completely moving out of the box body, the front end of the middle plate surface 323 is still located at the moving port 330.

[0081] Optionally, the second rack 350 is disposed in the middle of the middle 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 driving shaft meshes with the second rack 350.

[0082] Optionally, both the avoidance port 211 and the moving port 330 are provided with notches to avoid the moving first rack 340 and second rack 350.

[0083] Optionally, the length of the first rack 340 is arranged according to the moving distance of the wind shield 300, and the length of the second rack 350 is arranged according to the moving distance of the middle 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.

[0084] 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 shield 300 to gradually extend from the avoidance port 211 into the air guide enclosure 210, and the second rack 350 rotates forward synchronously to ensure that the middle 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 middle plate surface 323 to gradually move out of the box body from the moving port 330, so as to perform filtering using the first filter screen 310 and the second filter screen 320. As Figure 7 shown, in the case where the middle plate surface 323 partially moves out of the box body, part of the ventilation opening 201 can be blocked, and the air at the ventilation opening 201 can be filtered. In this way, the multiple needs of users can be met.

[0085] The embodiments of the present disclosure also provide 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 double-pipe heat exchanger; the condenser 140 includes an inner pipe and an outer pipe, the inner pipe is sleeved in the outer pipe and a fluid channel is formed between the inner pipe and the outer pipe; wherein, the inner pipe 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, the water inlet end of the hot water pipe is connected to the water outlet end of the inner pipe 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 pipe through a second solenoid valve. Here, the kitchen air conditioner includes the kitchen air conditioner described in any of the above embodiments.

[0086] In this embodiment, low-temperature cooling water is injected from the water inlet end of the inner pipe, 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 pipe. When the first solenoid valve is opened, the high-temperature cooling water enters the hot water pipe, and 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 pipe 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 are realized by using the circulation of the cooling water.

[0087] Optionally, the air conditioner thawing table combined system further includes a water collecting tank, and the water in the water collecting tank is used as cooling water. The water inlet end of the inner pipe is connected to the water outlet of the water collecting tank, and the water outlet end is connected to the water return port of the water collecting tank through a fifth solenoid valve. A temperature sensor is provided at the water outlet end of the inner pipe. When the thawing table is working and the temperature at the water outlet end of the inner pipe reaches the thawing temperature, the first solenoid 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 solenoid valve is opened. When the thawing table is not working, the fifth solenoid valve is opened to drain 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.

[0088] 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 is connected to the second water receiving tray 220 through a condensate pipe 221.

[0089] 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.

[0090] Optionally, a drain pump 230 is provided in the second water receiving tray 220. The drain pump 230 has a first drain pipeline, and the first drain pipeline is connected to the water inlet end of the hot water pipe through a third solenoid valve.

[0091] In this embodiment, the temperature of the condensed water rises after exchanging heat with the high-temperature refrigerant. When the third solenoid valve is opened, the high-temperature condensed water enters the hot water pipe. In this way, both the high-temperature cooling water and the high-temperature condensed water can flow into the hot water pipe to thaw items.

[0092] Optionally, the drain pump 230 is configured to drain water through the first drain pipeline when the thawing table is working and the temperature of the condensed water is greater than or equal to the thawing temperature. When the temperature of the condensed water is less than the thawing temperature, the kitchen air conditioner is controlled to reduce the air volume.

[0093] In this embodiment, a temperature sensor is provided in the second water receiving tray 220. When the temperature of the condensed water is greater than or equal to the thawing temperature, the third solenoid valve is opened, and the drain pump 230 discharges the high-temperature condensed water into the hot water pipe through the first pipeline. When the temperature of the condensed water is less than the thawing temperature, the third solenoid valve is not opened temporarily, and after the kitchen air conditioner reduces the air volume, the collection rate of the low-temperature condensed water in the second water receiving tray 220 slows down, which is beneficial to the temperature of the condensed water in the second water receiving tray 220 rising rapidly to be greater than or equal to the thawing temperature.

[0094] In this embodiment, since there is more oil fume in the air in the kitchen scenario, when the air exchanges heat with the evaporator 130, the condensed water will contain oil stains. Since the diameter of the heating pipe is relatively thin and dense, when the condensed water flows 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 roles of reducing the air volume and filtering the oil stains.

[0095] 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 rotate reversely, 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 not blocked by the middle plate surface 323 can filter the oil stains, and the middle plate surface 323 that has not moved out of the box can play the role of reducing the air volume.

[0096] Optionally, the drain pump 230 also has a second drain pipeline, and the second drain pipeline 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 pipeline.

[0097] Optionally, the drain pump 230 is configured to drain water through the second drain pipe when the condensate water level is greater than the drain water level. In this way, condensate water overflow can be avoided.

[0098] Optionally, the drain pump 230 is configured to drain water through the second drain pipe when the temperature of the condensate water is greater than or equal to the temperature of the cooling water at the water outlet end of the inner pipe.

[0099] In this embodiment, when the temperature of the condensate 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 condensate water is not conducive to the condensation of the condenser 140. At this time, if the thawing table does not need to work, the condensate water is directly discharged to the external environment.

[0100] Optionally, when the thawing table is working and the condensate water is discharged into the heating pipe, first, all the existing condensate water in the second water receiving tray 220 is discharged to the external environment, and here the drain pump 230 is used to drain water through the second drain pipe. Then, the ventilation opening 201 is completely blocked by the baffle, and at the same time, the middle plate surface 323 is completely moved out of the box body. Here, the first motor 342 is used to drive the baffle to move, and the second motor 352 is used to drive the middle plate surface 323 to move. In this way, relatively clean condensate water accumulates again and quickly in the second water receiving tray 220. Then, when the condensate water accumulates to the thawing water level and the temperature of the condensate water is greater than or equal to the thawing temperature, the condensate water is discharged into the heating pipe, and here the drain pump 230 is used to drain water through the first pipe. When the condensate water accumulates to the first thawing water level but the temperature of the condensate water is still less than the thawing 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 condensate water is slowed down so that the temperature of the condensate water rises rapidly. When the temperature of the condensate water gradually rises to be greater than or equal to the thawing temperature, the condensate water is then discharged into the heating pipe. Here, the thawing water level is lower than the drain water level. If the temperature is still less than the thawing temperature when the water level is higher than the drain water level, only the part of the condensate water higher than the drain water level is discharged through the second drain pipe.
