For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] Reference below Figure 1-Figure 12 A kitchen air handling system 100 according to an embodiment of the present invention is described.

[0048] According to the kitchen air treatment system 100 of the embodiment of the present invention, Figure 1-Figure 3 As shown, the kitchen air treatment system 100 includes: a first heat exchange split body 1 and a second heat exchange split body 2 arranged outside the first heat exchange split body 1 .

[0049] The kitchen air treatment system 100 further includes: a compressor 10 , a smoke-inhaling split body 3 , an air-collecting split body 4 , a first control valve 51 and a second control valve 52 .

[0050] The kitchen air treatment system 100 can be used independently in the kitchen. The kitchen air treatment system 100 has cooling and / or heating functions and can be used to change the ambient temperature in the kitchen. The smoke extraction split 3 is used to extract the fumes generated when cooking in the kitchen. The air collecting split 4 can guide the fumes extracted by the hood and provide negative pressure for the hood to extract the fumes. The air collecting split 4 can also drive the airflow to exchange heat with the first heat exchange split 1 and then discharge it outdoors.

[0051] In the related art, the air conditioner in the kitchen has a low integration degree and a large number of parts. Both the hood and the air conditioner need to guide the airflow, but they cannot share the same fan. At the same time, the air outlet position of the air conditioner is limited. The air outlet position is far away from the user's position when cooking, and the ambient temperature of the user when cooking in the kitchen cannot be guaranteed. To solve this problem, the kitchen air treatment system 100 proposed in the solution of this application highly integrates the heat exchange part and the smoke extraction part.

[0052] Reference Figure 1 The first heat exchanger 11 is provided in the first heat exchange split body 1. The first heat exchange split body 1 has a first air inlet 12 and a first air outlet 13. The first air inlet 12 is used to communicate with the outside. That is, the first heat exchange split body 1 can take in air from the outside.

[0053] The second heat exchange split body 2 is provided with a second heat exchanger 21 and a first fan 22, and the second heat exchange split body 2 has a second air inlet 23 and a second air outlet 24. The second air inlet 23 can be used to connect to the indoor, that is, the second heat exchange split body 2 can take in air from the indoor, for example, the second air inlet 23 can be connected to the kitchen or the living room. The second air inlet 23 can also be used to connect to the outdoor, so that the second heat exchange split body 2 can absorb fresh air from the outdoor. There can also be multiple second air inlets 23, connecting the indoor and outdoor respectively. The second air outlet 24 is used to connect to the indoor, and the second heat exchange split body 2 can blow air into the indoor.

[0054] The compressor 10 is connected to the first heat exchanger 11 and the second heat exchanger 21 respectively. The compressor 10 can drive the refrigerant to flow between the first heat exchanger 11, the throttling device, the second heat exchanger 21, etc., so that when one of the first heat exchanger 11 and the second heat exchanger 21 is cooling, the other one is heating.

[0055] The first heat exchanger 11 and the second heat exchanger 21 can be connected through a refrigerant pipeline, and a compressor 10 and throttling parts and other components are arranged on the refrigerant pipeline so that the first heat exchanger 11 and the second heat exchanger 21 can complete the Carnot cycle. Here, the compressor 10, the first heat exchanger 11, the second heat exchanger 21 and other components connected to the refrigerant pipeline can be collectively referred to as a heat pump circulation system. The refrigerant flow direction of the heat pump circulation system can be fixed, and the compressor 10 can only allow the first heat exchanger 11 to absorb heat when it is running, or the compressor 10 can only allow the second heat exchanger 21 to absorb heat when it is running; the refrigerant flow direction of the heat pump circulation system can also be variable, for example, the refrigerant flow direction in the first heat exchanger 11 is opposite during cooling and heating. According to user needs, other components can also be arranged on the heat pump circulation system, such as a three-way valve, a filter, a liquid storage tank, etc., which are not specifically limited here.

[0056] Reference Figure 1 The smoking part 3 has a smoking port 31 and a smoke outlet 32, and a fume treatment component (not shown) is disposed on the smoking part 3. The position of the fume treatment component on the smoking part 3 is not limited, and the fume treatment component can be disposed at the smoking port 31, or disposed on the inner wall of the smoking part 3. In some schemes, the fume treatment components can be multiple, for example, a condensation plate is disposed at the smoking port 31 as the first fume treatment component, and a filter grille is disposed around the condensation plate as the second fume treatment component. In other schemes, when the filter grille is disposed, a single layer or multiple layers can be disposed. In some schemes, the fume treatment component includes a filter disposed on the inner wall of the smoking part 3, such as various carbon particles.

[0057] The smoking port 31 is used to connect to the room. In some embodiments, the smoking port 31 is arranged at the bottom of the smoking split body 3, so that it is close to the stove, which is conducive to timely suction of more oil smoke into the smoking split body 3. The appearance of the smoking split body 3 here can refer to the appearance structure of the range hood in the prior art, and can adopt the appearance of a near-suction range hood or the appearance of a top-suction range hood. In some schemes, a smoke hood is also provided at the bottom of the smoking split body 3, and the smoking port 31 is located at the bottom of the smoke hood, thereby appropriately increasing the area of ​​the negative pressure zone and increasing the suction range. Of course, in some schemes, the smoking port 31 can also be provided on the front side, left and right sides of the smoking split body 3 to further increase the suction range.

[0058] A second fan 41 is provided in the gas collecting split body 4, and the gas collecting split body 4 has: a first gas collecting inlet 42, a second gas collecting inlet 43 and a gas collecting outlet 44. The first gas collecting inlet 42 is connected to the first air outlet 13, the second gas collecting inlet 43 is connected to the smoke outlet 32, and the gas collecting outlet 44 is used to connect to the outside. The first control valve 51 is used to control the switch of the first gas collecting inlet 42, and the second control valve 52 is used to control the switch of the second gas collecting inlet 43.

[0059] That is, the second fan 41 can act on the smoking sub-unit 3 and the first heat exchange sub-unit 1 at the same time, respectively providing power for the airflow in the smoking sub-unit 3 and the first heat exchange sub-unit 1. The first control valve 51 and the second control valve 52 are arranged so that the second fan 41 can selectively serve the smoking sub-unit 3 and the first heat exchange sub-unit 1.

[0060] The gas collecting sub-body 4 is arranged so that the gas after heat exchange in the first heat exchanging sub-body 1 and the smoke after filtering in the smoking sub-body 3 can be driven by the second fan 41 and discharged toward the outside. After such arrangement, the discharge of the two gases can be arranged in the same pipeline system. Figure 1-Figure 3 In the embodiment, the gas collecting outlet 44 is connected to the pipe body 7, and the pipe body 7 connected to the gas collecting outlet 44 extends to the flue 71. In this way, the number of pipelines is small, the pipelines are shortened, and the occupied volume of the structure and the difficulty of pipeline layout can be greatly reduced.

[0061] In the solution of the present application, since the second fan 41 can drive the flow of smoke in the smoking split 3 and can also drive the flow of air in the first heat exchange split 1, the second fan 41 is a dual-purpose machine. By using the setting of the gas collecting split 4, it is not necessary to set a fan in the smoking split 3 and the first heat exchange split 1, so that the volume of the smoking split 3 and the first heat exchange split 1 is greatly reduced. The smoking split 3 and the first heat exchange split 1 can leave more space for the kitchen due to the small volume occupied during use. Among them, the main function of the smoking split 3 is to remove oil after smoking. It is usually set above or in front of the stove. After the fan in the smoking split 3 is cancelled, it can be designed to be thinner or flatter and more lightweight. The first heat exchange split 1 is mainly used for heat exchange and can also be used to bring in fresh air. After the gas collecting split 4 is set, it is no longer necessary to set a fan in the first heat exchange split 1. At this time, the first heat exchange split 1 can occupy a smaller body, which helps to find a suitable location for installation.

[0062] The first heat exchange split body 1 in this application has roughly the same function as the outdoor unit in a conventional split air conditioner, and the second heat exchange split body 2 has roughly the same function as the indoor unit in a conventional split air conditioner. The difference is that in this application, the first air outlet 13 of the first heat exchange split body 1 is connected to the air collecting split body 4 through the pipeline 7, and the air after heat exchange can be discharged through the air collecting split body 4. At this time, the first heat exchange split body 1 is installed indoors, and the first heat exchange split body 1 can also exchange heat with the outdoor air normally, and there is no need to set up an outdoor unit outside the kitchen.

[0063] When the volume of the first heat exchange split body 1 is reduced, the first heat exchange split body 1 can be centrally installed at the second heat exchange split body 2. After being connected, the overall size is not too large, and it can be installed in a suitable position in the kitchen. This arrangement can integrate the two heat exchange split bodies into one, improve the integration of the air conditioning part of the system, and make the installation simpler and more convenient.

[0064] A communicating reversing air port 20 is provided between the first heat exchanging sub-body 1 and the second heat exchanging sub-body 2 , and the reversing valve 50 is used to control the switch of the reversing air port 20 .

[0065] It can be understood that in the solution of the present application, the second heat exchange split body 2 blows the air into the room after absorbing the air, while the first air inlet 12 of the first heat exchange split body 1 can absorb fresh air from the outside. Therefore, in some solutions, when fresh air needs to be introduced into the room, the reversing air vent 20 can be opened. At this time, only the first fan 22 is turned on, and then the first control valve 51 is closed, so that the external air can be driven to flow into the second heat exchange split body 2, and then blown into the room from the second air outlet 24. This process is as follows Figure 5 As shown, at this time, the kitchen air treatment system 100 has the function of a ventilation fan. In other schemes, the first air inlet 12 and the second air inlet 23 are both connected to the outdoors. At this time, the first fan 22 is turned on, and then the first control valve 51 is closed, which can drive the outdoor fresh air to flow into the first heat exchange split 1 and the second heat exchange split 2, and then blow to the outdoors, so as to achieve the function of ventilating the two heat exchange splits. In some schemes, a disinfection device is provided in the first heat exchange split 1 or the second heat exchange split 2. After the heat exchange split is disinfected, the contaminated air after disinfection can be discharged to the outdoors. Of course, in this scheme, the disinfected air can also be discharged to the outdoors from the air collecting split 4, which is not limited here.

[0066] Since the second air outlet 24 is connected to the room, the second air outlet 24 can also be used as a smoke inlet in some working modes. In some working modes, when the second fan 41 is working, it not only absorbs oil smoke from the smoke outlet 31, but also can absorb smoke from the second air outlet 24 when the reversing air outlet 20 and the first control valve 51 are opened, so that the smoking range is larger.

[0067] It is understandable that when cooking in the kitchen, the smoke is often concentrated at the stove, but there will inevitably be some smoke in the surrounding space. At this time, the smoking split body 3 can be set to focus on smoking at the stove, and the second air outlet 24 can be used for smoking around, so that the overall smoking effect can be enhanced.

[0068] In another working mode, when the smoking split body 3 is smoking, the reversing air outlet 20 is opened, the first control valve 51 is closed, the first fan 22 is started, and air is sucked from the outside. In this way, a slight negative pressure is formed at the smoking port 31, and a slight positive pressure is formed at the second air outlet 24. The air blown out of the second air outlet 24 can help the kitchen air to flow to the smoking port 31 more easily. In this case, not only can the smoking effect be improved, but also the user can breathe fresh air, killing two birds with one stone.

[0069] Therefore, the kitchen air treatment system 100 can obtain a large number of working modes, and is more convenient and flexible to use.

[0070] In some embodiments, Figure 1 As shown, the first heat exchange split body 1 is used for heating, and the first heat exchange split body 1 also has a shell, the first air inlet 12 is arranged on the shell of the first heat exchange split body 1, and the first air outlet 13 is arranged on the shell of the first heat exchange split body 1 at a distance therefrom, and the first heat exchanger 11 is optionally arranged between the first air inlet 12 and the first air outlet 13, so that the airflow flowing in from the first air inlet 12 can exchange heat with the first heat exchanger 11, and the airflow can flow out from the first air outlet 13 after taking away the heat generated by the first heat exchanger 11, thereby increasing the working efficiency of the heat exchange. In some specific embodiments, the first heat exchanger 11 is a condenser.

[0071] like Figure 1-Figure 3 As shown, the first air inlet and outlet 12 and 13 are both connected to a tube body 7, and the tube body 7 is connected to the outside, so that the outdoor air can be conducted into the first heat exchange split body 1, and after heat exchange with the condenser, the air flow is discharged from the tube body 7 of the first air outlet 13.

[0072] In some embodiments, Figure 1 and Figure 2 As shown, the second heat exchange split body 2 can absorb the heat of the air flowing through it. A second heat exchanger 21 is provided inside the second heat exchange split body 2. The second heat exchange split body 2 is also provided with a first fan 22 which can drive the air to flow through the second heat exchanger 21.

[0073] The second heat exchange split body 2 has a shell, the second air inlet 23 is provided on the shell of the second heat exchange split body 2, and the second air outlet 24 is provided on the shell of the second heat exchange split body 2 at a distance therefrom. The second heat exchanger 21 and the first fan 22 can be arranged between the second air inlet 23 and the second air outlet 24, so that the airflow flowing in from the second air inlet 23 can be heat exchanged with the second heat exchanger 21 and then flow out from the second air outlet 24, thereby increasing the heat exchange efficiency of the airflow.

[0074] In some specific embodiments, the second heat exchanger 21 is an evaporator, the evaporator is installed close to the second air inlet 23, and the first fan 22 is connected close to the second air outlet 24. This installation method can quickly guide the refrigeration airflow cooled by the evaporator out of the second air outlet 24.

[0075] In some embodiments, Figure 1 As shown, the second air inlet 23 is connected to the pipe body 7 and the air inlet of the air conditioner, the second air inlet 23 can inhale air from the room, and the second air outlet 24 is connected to the pipe body 7.

[0076] The second air inlet and outlet 23 and 24 are both connected to the room, and a cold air circulation is formed between the second heat exchange split body 2 and the kitchen. That is, the air in the kitchen flows into the second heat exchange split body 2 from the second air inlet 23, and after heat exchange, the low-temperature air flows into the room from the second air outlet 24. After the low-temperature air enters the room, heat exchange is performed to reduce the room temperature. The room is a relatively closed space, and the indoor air will be guided into the second heat exchange split body 2 by the first fan 22 again, and heat exchange is performed with the second heat exchanger 21 again. The second air inlet 23 sucks air from the room to reduce the room temperature relatively quickly, shortening the cooling effect time.

[0077] In other embodiments, Figure 2 and Figure 3 As shown, the second air inlet 23 is connected to the pipe body 7, the second air inlet 23 is connected to the outside, and the second air outlet 24 is connected to the pipe body 7 and connected to the room. Compared with the design method of connecting the second air inlet 23 to the room, connecting the second air inlet 23 to the outside can reduce the volume occupied by the kitchen air treatment system 100, which is convenient for use, and the air flowing in from the outside and then cooling and flowing into the room can improve the indoor air quality and accelerate the air circulation between the indoor and outdoor.

[0078] like Figure 1-Figure 3 As shown, a compressor 10 is provided to connect the first heat exchanger 11 and the second heat exchanger 21. The second heat exchanger 21 can cool the air in the kitchen. The first heat exchange split body 1 discharges the heat generated in the heat exchange from the first air outlet 13 to form a heat cycle. The installation position of the compressor 10 is very flexible, and it can be adjacent to the first air inlet 12 in the first heat exchange split body 1. Or the compressor 10 is in the second heat exchange split body 2, adjacent to the second air inlet 23. Or the compressor 10 is independently installed outside the two split bodies. In some specific embodiments, the compressor 10 is installed in the first heat exchange split body 1, making full use of the space in the first heat exchange split body 1, and can use the air flowing through to cool the compressor 10, and reducing the number of independently installed devices can reduce the difficulty of installation.

[0079] In some embodiments, Figure 1-Figure 3 As shown, the function of the smoke extractor 3 is similar to that of a range hood, and the smoke extractor 3 has a smoke inlet 31 and a smoke outlet 32, wherein the smoke outlet 32 ​​is located above the smoke inlet 31, and the smoke inlet 31 can inhale air from the room, and can inhale the indoor fumes through the smoke inlet 31 and discharge them from the smoke outlet 32. In some specific embodiments, the oil droplets in the fumes can be condensed and collected in an oil collection box, thereby reducing the pollution of the fumes to the fumes pipe of the smoke extractor 3.

[0080] In some specific embodiments, the area of ​​the smoke inlet 31 is larger than the area of ​​the smoke outlet 32, and the smoke inlet 31 has a guide shell. This design can increase the smoking area and speed up the cleaning of oil smoke in the kitchen.

[0081] In some embodiments, Figure 1-Figure 3 As shown, the gas collecting sub-body 4 is used to collect the gas to be treated and then discharge it in a centralized manner. The first gas collecting inlet 42 of the gas collecting sub-body 4 is connected to the first air outlet 13 through a pipeline. The airflow after heat exchange through the first heat exchange sub-body 1 flows out from the first air outlet 13 and can flow into the sub-body through the first gas collecting inlet 42. The second gas collecting inlet 42 is connected to the smoke outlet 32 ​​through the flue 71. The oil fume entering through the smoking sub-body 3 flows out from the smoke outlet 32 ​​and can flow into the gas collecting sub-body 4 through the second gas collecting inlet 43. The second fan 41 can guide the airflow in the first heat exchange sub-body 1 or the smoking sub-body 3 into the gas collecting sub-body 4 through the first gas collecting inlet 42 or the second gas collecting inlet 43. The gas collecting outlet 44 is connected to the outside, and the gas collected in the gas collecting sub-body 4 can be discharged to the outside. The air circulates and purifies the airflow.

[0082] In some specific embodiments, the gas flow route between the first heat exchange split body 1 and the gas collection split body 4 may be: outdoor air flows into the first heat exchange split body 1 through the first air inlet 12, and after heat exchange through the first heat exchanger 11, the heat exchange gas flows into the gas collection split body 4 through the first air outlet 13 and the first gas collection inlet 42 under the action of the second fan 41, and flows out of the outdoors from the gas collection outlet 44 through the second fan 41. The gas flow route between the smoking split body 3 and the gas collection split body 4 may be: indoor oil smoke is sucked into the smoking port 31 under the action of the second fan 41, and after passing through the oil smoke treatment component of the smoking split body 3, it flows into the gas collection split body 4 through the smoke outlet 32, the flue 71 and the second gas collection inlet 43, and flows out of the outdoors from the gas collection outlet 44 through the second fan 41.

[0083] In some specific embodiments, the second fan 41 is a centrifugal fan, and the exhaust port of the centrifugal fan is installed toward the air collecting outlet 44. The use of the centrifugal fan can uniformly guide the airflow in multiple directions and discharge it to the air collecting outlet 44, which can reduce the occurrence of airflow turbulence inside the kitchen air treatment system 100.

[0084] In some specific embodiments, the air collecting outlet 44 is connected to the smoke exhaust duct 71 in the kitchen, and the airflow and oil smoke after heat exchange are directly discharged into the smoke exhaust duct 71 reserved in the kitchen, which is convenient and fast and can reduce the difficulty of installing the kitchen air treatment system 100.

[0085] like Figure 1-3As shown, the first control valve 51 is disposed between the first air collection inlet 42 and the first air outlet 13 to control the gas flow between the first heat exchange sub-body 1 and the air collection sub-body 4, and the second control valve 52 is located between the second air collection inlet 43 and the smoke outlet 32 ​​to control the gas flow between the smoking sub-body 3 and the air collection sub-body 4. It can be understood that the first control valve 51 and the second control valve 52 do not interfere with each other, so the air heat exchange process of the first heat exchange sub-body 1 and the smoking process of the smoking sub-body 3 are also independent processes, which can be carried out simultaneously or independently.

[0086] In some other specific embodiments, the first control valve 51 may also be used to control the opening and closing of the first air outlet 13 , and the second control valve 52 may also be used to control the opening and closing of the smoke outlet 32 ​​.

[0087] It can be understood that the second control valve 52 is used to control the gas flow between the smoking split 3 and the gas collecting split 4, but it is generally not used to control the switch of the smoking port 31. When the second control valve 52 controls the second gas collecting inlet 43 or the smoke outlet 32, when the first heat exchange split 1 and the gas collecting split 4 are operated separately, the connection between the gas collecting split 4 and the smoking split 3 can be blocked, which can reduce the situation where the hot air flow flowing in from the first heat exchange split 1 escapes from the smoking port 31, and at the same time can reduce the hot air flow entering the smoking split 3 and causing secondary pollution to the oil fume duct of the smoking split 3.

[0088] In some specific embodiments, the first control valve 51 and the second control valve 52 can adjust and control the air volume entering the kitchen air treatment system 100 to achieve matching of different air flows and functions.

[0089] like Figure 1-Figure 3 As shown, a reversing air vent 20 is provided between the first and second heat exchange split bodies 1 and 2, and the opening and closing of the reversing air vent 20 can be controlled by a reversing valve 50. By providing the reversing air vent 20, the functionality of the kitchen air treatment system 100 can be increased, such as Figure 1 As shown in the embodiment, the second air inlet 23 of the second heat exchange split body 2 is connected to the indoor air. Figure 2 The second heat exchange split body 2 of the embodiment, Figure 1 Although the second air inlet 23 connected to the room can quickly lower the room temperature, it lacks the function of introducing outdoor air into the room to promote air circulation. After adding the reversing air vent 20 between the first and second heat exchange split bodies 1 and 2, when the first heat exchanger 11 is not started, the reversing air vent 20 is opened, and the outdoor air can flow into the room through the first air inlet 12, the reversing air vent 20, and the second heat exchange split body 2, thereby regulating the indoor and outdoor air circulation and increasing the indoor fresh air, i.e., the fresh air exchange function.

[0090] In addition, Figure 1As shown in the embodiment, the second air inlet 23 of the second heat exchange split body 2 can inhale air from the room. The second air inlet 23 can inhale indoor air. Without starting the first fan 22 in the second heat exchange split body 2, the reversing air port 20 is opened, and the indoor air can flow out of the room through the second air inlet 23, the reversing air port 20, the first heat exchange split body 1 and the air collecting split body 4, which can assist the smoking split body 3 in performing the smoking function. It can be understood that the smoking port 31 is facing the kitchen utensils that produce oil smoke, but some of the oil smoke will not be sucked into the smoking port 31, but will escape into the room. In this case, the second air inlet 23 can assist the smoking port 31 in performing the smoking function, and the oil smoke escaped in the kitchen room is sucked in for the second time, which can improve the cleaning ability of the kitchen air treatment system 100 and increase the functionality.

[0091] Moreover, the kitchen air treatment system 100 of the present proposal can be provided with at least one of a variety of functions such as cooling, heating, dehumidification, purification, fume removal, and fresh air exchange, which are described in detail in the specific embodiments of the specification.

[0092] The kitchen air purification device according to the embodiment of the present invention eliminates the restriction of external unit installation through the coordinated arrangement of structures, thereby reducing the difficulty of installation and saving kitchen use space. At the same time, multiple functional parts are integrated and cleverly coordinated with each other, so as to realize multiple functional uses and improve functionality.

[0093] In some embodiments, Figure 1-Figure 3 As shown, the second heat exchange split body 2 includes a first purification component 231 arranged corresponding to the second air inlet 23, so that the first purification component 231 filters and cleans the inhaled air.

[0094] In some other embodiments, the second heat exchange split body 2 includes a second purification component 201 disposed at a location corresponding to the reversing air port 20 , so that when air flows through the heat exchange air port 20 , it can be filtered and cleaned.

[0095] In some other embodiments, the second heat exchange split body 2 includes a first purification element 231 and a second purification element 201 .

[0096] The second air inlet 23 delivers air from indoors or outdoors into the second heat exchange split body 2 for air cooling. A purification element is provided at the second air inlet 23 to filter and purify the inflowing air, thereby purifying the air delivered to the room and regulating the indoor air.

[0097] like Figure 1As shown in the embodiment, when the second air inlet 23 can exchange air with the indoor air, the indoor air is sucked into the first fan 22 in the second heat exchange split body 2, and the indoor air passes through the first purification element 231. The first purification element 231 can filter out dust, oil smoke, etc. in the air. The filtered air is heat exchanged through the second heat exchanger 21 and then discharged from the second air outlet 24, which can improve the indoor air quality and purify the indoor air.

[0098] like Figure 2 and Figure 3 As shown in the embodiment, when the second air inlet 23 can exchange air with the outdoors, the outdoor air is sucked in by the first fan 22 in the second heat exchange split body 2, and the outdoor air passes through the first purification component 231. The first purification component 231 can purify the outdoor air and filter out dust and other impurities in the outdoor air. The filtered air is heat exchanged through the second heat exchanger 21 and then discharged from the second air outlet 24, which can improve the indoor air quality and purify the indoor air.

[0099] In addition, by adding the first purification component 231, most of the debris can be blocked outside the second heat exchange split body 2, thereby reducing the contamination of the second heat exchanger 21 in the second heat exchange split body 2 and the contamination of the first fan 22 in the second heat exchange split body 2, thereby improving the cleanliness. Compared with disassembling the second heat exchange split body 2 for cleaning, cleaning or replacing the first purification component 231 is more cost-effective and reduces the difficulty of cleaning, thereby reducing the difficulty of cleaning the kitchen air treatment system 100.

[0100] In some specific embodiments, there may be multiple first purification components 231, and different types of purification components may be selectively installed at the second air inlet 23 according to different needs. In some specific embodiments, the first purification component 231 is a filter screen, which is light in weight and does not burden the kitchen air treatment system 100. It is also easy to install and disassemble, and is convenient for replacement and cleaning.

[0101] In some embodiments, Figure 1-Figure 3 As shown, the reversing air outlet 20 has a second purification component 201, which can filter the airflow passing through the reversing air outlet 20, protect the interior of the kitchen air treatment system 100, such as the interior of the first and second heat exchange split bodies 1 and 2, reduce the probability of debris entering, and purify the passing airflow, thereby improving the cleanliness of the delivered airflow.

[0102] like Figure 1As shown in the embodiment, when the reversing air outlet 20 is opened, outdoor air can flow through the first air inlet 12, the reversing air outlet 20, and the second heat exchange split body 2 to adjust the indoor and outdoor air circulation and increase the indoor fresh air. The second purification element 201 can purify the outdoor air and filter out dust and other impurities in the outdoor air, which can improve the indoor air quality and improve the indoor air. In addition, the indoor air can also flow out of the room through the second air inlet 23, the reversing air outlet 20, the first heat exchange split body 1 and the gas collection split body 4, which can assist the smoking split body 3 in smoking. The second purification element 201 can filter the indoor air to reduce the pollution of the inner wall of the first heat exchange split body 1, the second heat exchange split body 2, etc. by impurities such as oil smoke.

[0103] Optionally, the first heat exchange split body 1 includes a third control valve 53 , and the third control valve 53 can open and close the first air inlet 12 .

[0104] Optionally, the second heat exchange split body 2 includes a fourth control valve 54 , and the fourth control valve 54 can open and close the second air inlet 23 .

[0105] In some solutions, the first heat exchange split body 1 includes a third control valve 53 , and the second heat exchange split body 2 includes a fourth control valve 54 .

[0106] like Figure 1-Figure 3 As shown, the first heat exchange split body 1 includes a third control valve 53, and the third control valve 53 can open and close the first air inlet 12, and the first air inlet 12 is used to exchange air with the outside and inhale outdoor air from the outside. Compared with setting the first air inlet 12 to a normally open state, adding the third control valve 53 can close the connection between the first air inlet 12 and the outside when necessary, thereby improving cleanliness and safety. When there is bad weather outdoors, such as rain or sandstorms, raindrops, sand and dust and other debris can enter the kitchen air treatment system 100 through the first air inlet 12, causing pollution to the interior. At this time, controlling the third control valve 53 to close the connection between the first air inlet 12 and the outside can isolate raindrops, sand and dust and other debris from the outside.

[0107] like Figure 2 and Figure 3 As shown in the embodiment, when the second air inlet 23 can exchange air with the outdoors, the fourth control valve 54 is provided in the same principle as the third control valve 53, so that the connection between the second air inlet 23 and the outside can be closed when necessary, thereby improving the cleanliness and safety of the kitchen air treatment system 100.

[0108] In some embodiments, an air-conditioning outlet 25 for sucking in air from the indoor room is provided on the smoking split body 3 , and the second air outlet 24 is connected to the air-conditioning outlet 25 through an indoor air duct 250 .

[0109] like Figure 3As shown in the embodiment, the second air outlet 24 can be connected to the indoor air duct 250, and the airflow passing through the second heat exchange split body 2 is guided to the air conditioning outlet 25 located on the smoking split body 3, so that the airflow passing through the second heat exchange split body 2 flows into the room from the smoking split body 3. Compared with setting a separate air conditioning outlet 25 to blow out cold air, setting the air conditioning outlet 25 on the smoking split body 3 can reduce the space occupied by the kitchen air treatment system 100 and improve the universality of the installation of the kitchen air treatment system 100. In addition, the main function of the smoking split body 3 is to absorb the fumes generated in the kitchen. In comparison, the smoking split body 3 will be closer to the stove and other parts that generate fumes, so the working environment temperature of the smoking split body 3 will be higher. Setting the air conditioning outlet 25 that can blow out cold air on the smoking split body 3 can reduce the ambient temperature around the smoking split body 3, and directional cooling of the highest temperature can improve the user experience. In addition, an air-conditioning outlet 25 is arranged above the smoking port to increase the shell temperature of the smoking compartment 3, assist the condensation function of the smoking compartment 3, cool the oil droplets in the oil smoke, and improve the cleanliness of the kitchen air treatment system 100. In addition, the air-conditioning outlet 25 at this position can blow out a wind curtain to separate the oil smoke from the user's face, thereby improving the user experience.

[0110] Specifically, the smoking port 31 is located at the bottom of the smoking split body 3 , and the air-conditioning outlet 25 is located above the smoking port 31 .

[0111] like Figure 3 As shown, generally, the smoking split body 3 faces the stove and other parts that generate oil smoke, and the smoking port 31 is located at the bottom of the smoking split body 3 and can be as close to the oil smoke generating part as possible, thereby improving the cleaning ability of the smoking split body 3. The air-conditioning outlet 25 is arranged on the upper part of the smoking port 31 to reduce the interference between the two. The smoking port 31 reduces the suction of cold air generated by the air-conditioning outlet 25, thereby reducing waste. In addition, when using the smoking split body 3, the user is generally located below the smoking split body 3. The air-conditioning outlet 25 is located above the user, and the cold air density generated is relatively large. The cold air naturally descends, which can effectively cool down and relieve heat for the user below, thereby improving the user's comfort and user experience.

[0112] In some embodiments, the kitchen air treatment system 100 further includes: a control terminal 6, which is used to control the operating state of the kitchen air treatment system 100, and the control terminal 6 is independently installed or arranged on the smoking split body 3 or on the second heat exchange split body 2.

[0113] like Figure 1 and Figure 2 As shown in the embodiment, the control terminal 6 can be installed independently, such as Figure 3As shown in the embodiment, the control terminal 6 can be arranged on the smoking sub-body 3. In addition, in some specific embodiments, the control terminal 6 can also be arranged separately, partly arranged on the smoking sub-body 3 and partly arranged on the second heat exchange sub-body 2, and this arrangement is also within the protection scope of this application.

[0114] In some specific embodiments, the kitchen air treatment system 100 is provided with a plurality of sensors, which can monitor the air quality in the kitchen room in real time. The sensors can be provided on the control terminal 6 for display and active control.

[0115] Optionally, at least one of the first heat exchange sub-body 1, the second heat exchange sub-body 2, and the smoking sub-body 3 is provided with a hanging part (not shown in the figure).

[0116] It can be understood that the kitchen air treatment system 100 is used in the kitchen. The conventional kitchen building space is small, and the available space in the kitchen is further reduced after the cupboards and stoves are installed. The kitchen air treatment system 100 of the present application can be installed with a hanging part, and the main split part can be installed on the kitchen ceiling, which saves kitchen space, reduces the layout requirements of the kitchen air treatment system 100, and improves the applicability of the kitchen air treatment system 100.

[0117] In some specific embodiments, the two heat exchange split units and the gas collection split unit 4 may be installed on the kitchen ceiling, and the smoking split unit 3 and the control terminal 6 may be installed on the kitchen wall.

[0118] Optionally, the two heat exchange splits and the smoking split 3 are installed separately; in some solutions, the two heat exchange splits are connected as one body, and the smoking split 3 is installed separately from the two heat exchange splits; in some solutions, the smoking split 3 is connected as one body with one of the heat exchange splits (such as the first heat exchange split 1), and the other heat exchange split is installed separately from the two heat exchange splits. In other solutions, the two heat exchange splits and the smoking split 3 are connected as one body.

[0119] In the above solution, the three are placed separately, or two of them are connected and installed as one, or all three are connected and installed as one. This placement method can improve the applicability of the kitchen air treatment system 100.

[0120] It is understandable that due to different building structures and different choices of later decoration, the kitchen structures of different users will be different. The split of the kitchen air treatment system 100 needs to occupy space. Some kitchen structures can connect the above three as a whole, and some kitchen structures can accommodate limited volume, so the above three are set separately and installed in the space respectively. This arrangement saves kitchen space, reduces the layout requirements of the kitchen air treatment system 100, and improves the applicability of the kitchen air treatment system 100.

[0121] Reference below Figure 4-Figure 8A control method of the kitchen air treatment system 100 according to an embodiment of the present invention is described.

[0122] According to the control method of the kitchen air treatment system 100 of the embodiment of the present invention, the kitchen air treatment system 100 is the kitchen air treatment system 100 according to the above embodiment, and the kitchen air treatment system 100 has: a cooling mode, a first fresh air mode, and a first smoke removal mode and a second smoke removal mode.

[0123] In the cooling mode, the first control valve 51 opens the first air collecting inlet 42, the second control valve 52 closes the second air collecting inlet 43, the reversing valve 50 closes the reversing air port 20, and the compressor 10, the first fan 22, and the second fan 41 are all running.

[0124] In the first fresh air mode, the first control valve 51 closes the first air collecting inlet 42, the second control valve 52 closes the second air collecting inlet 43, the reversing valve 50 opens the reversing air port 20, and the first fan 22 operates.

[0125] In the first smoke removal mode, the first control valve 51 closes the first air collection inlet 42, the second control valve 52 opens the second air collection inlet 43, and the second fan 41 is turned on and operated.

[0126] In the second smoke removal mode, the first control valve 51 closes the first air collection inlet 42, the second control valve 52 opens the second air collection inlet 43, the reversing valve 50 opens the reversing air port 20, and both the first fan 22 and the second fan 41 are in operation.

[0127] The control method of the kitchen air treatment system 100 of the embodiment of the present invention is a method of operating multiple functions because the kitchen air treatment system 100 described in the above embodiment is provided with multiple functional divisions and forms a clever mutual coordination.

[0128] like Figure 4 As shown, in the refrigeration mode, after the first air collecting inlet 42 is opened by the first control valve 51, the airflow of the first heat exchange split 1 can flow to the air collecting split 4, and after the second air collecting inlet 43 is closed by the second control valve 52, the smoke in the smoking split 3 cannot flow to the air collecting split 4, thereby achieving airflow blocking connectivity.

[0129] After the reversing air port 20 is closed by the reversing valve 50, the air flow between the first and second heat exchange split bodies 1 and 2 is blocked. The first fan 22 is running, and air is sucked in from the second air inlet 23. The air passes through the second heat exchanger 21 for heat exchange. Under the guidance of the first fan 22, the cooled refrigeration airflow flows into the room from the second air outlet 24 to reduce the room temperature and perform the refrigeration function. Through the operation of the compressor 10, the first heat exchanger 11 is heating, and the second heat exchanger 21 is cooling. The second fan 41 is running, and the first air inlet 12 connected to the outside transports the outdoor air into the first heat exchange split body 1. The outdoor air passes through the first heat exchange split body 1 to perform heat exchange with the first heat exchanger 11, which plays a role in cooling the first heat exchanger 11. The cooled airflow passes through the first air outlet 13 and the air collecting split body 4 under the guidance of the second fan 41 and is discharged into the flue 71. The second heat exchange split body 2 cools the indoor air, and the first heat exchange split body 1 cools the heat generated by the machine refrigeration.

[0130] like Figure 5 As shown, the second air inlet 23 can inhale air from the room. In the first fresh air mode, the first air collection inlet 42 is closed by the first control valve 51, blocking the connection between the first heat exchange split 1 and the air collection split 4, and the second air collection inlet 43 is closed by the second control valve 52, blocking the connection between the smoking split 3 and the air collection split 4, and the reversing valve 50 opens the reversing air port 20 to connect the first and second heat exchange splits 1 and 2. The first fan 22 is running, and suction is generated in both the first and second heat exchange splits 1 and 2. Outdoor air flows into the first heat exchange split 1 from the first air inlet 12 under the action of suction. Because it is blocked from connecting with the air collection split 4, outdoor air can only enter the second heat exchange split 2 through the reversing air port 20 under the action of the first fan 22, and flow out from the second air outlet 24, introducing outdoor fresh air into the room, improving air circulation, and generating the first fresh air mode of fresh air.

[0131] like Figure 6 As shown, in the first smoke removal mode, the first air collection inlet 42 is closed by the first control valve 51, blocking the connection between the first heat exchange split body 1 and the air collection split body 4, and the second air collection inlet 43 is opened by the second control valve 52, connecting the smoking split body 3 and the air collection split body 4. The second fan 41 is running, and the indoor gas enters the smoking split body 3 through the smoking port 31, and flows to the air collection split body 4 under the action of the second fan 41. Because the air collection split body 4 is blocked from connecting with the first heat exchange split body 1, the indoor gas flows to the air collection outlet 44 under the action of the second fan 41, and is discharged from the flue 71. The indoor gas, which is sucked in the first smoke removal mode, is basically oil smoke, which can be discharged from the room through the smoking split body 3.

[0132] like Figure 7As shown, in the second smoke removal mode, the first control valve 51 closes the first air collection inlet 42 to connect the first heat exchange split body 1 and the air collection split body 4, the second control valve 52 opens the second air collection inlet 43 to connect the smoking split body 3 and the air collection split body 4, and the reversing valve 50 opens the reversing air port 20 to connect the first and second heat exchange split bodies 1 and 2. The second fan 41 is running, the indoor gas enters the smoking split body 3 through the smoking port 31, flows to the air collection split body 4 under the action of the second fan 41, flows to the air collection outlet 44 under the action of the second fan 41, and is discharged from the flue 71, and the first fan 22 is running. The outdoor gas enters the first heat exchange split body 1 through the first air inlet 12, and can enter the second heat exchange split body 2 through the reversing air port 20, and flows to the second air outlet 24 under the action of the second fan 41, and flows into the room. When the smoking split body 3 is running, fresh air is introduced from the outside while removing the indoor gas, thereby increasing the indoor air circulation speed.

[0133] By providing a plurality of functional divisions and forming ingenious mutual coordination, a method of operating a plurality of functions can be provided, thereby improving the functionality of the kitchen air treatment system 100.

[0134] Specifically, when the second air inlet 23 exchanges air with the outside, the kitchen air treatment system 100 has: a second fresh air mode and a third smoke removal mode. In the second fresh air mode, the first control valve 51 closes the first air collection inlet 42, the second control valve 52 closes the second air collection inlet 43, the reversing valve 50 closes the reversing air port 20, and the first fan 22 operates; in the third smoke removal mode, the first control valve 51 closes the first air collection inlet 42, the second control valve 52 opens the second air collection inlet 43, the reversing valve 50 closes the reversing air port 20, and both the first fan 22 and the second fan 41 operate.

[0135] like Figure 8 As shown, the second air inlet 23 exchanges air with the outside. In the second fresh air mode, the first control valve 51 closes the first air collection inlet 42, blocking the connection between the first heat exchange split body 1 and the air collection split body 4. The second control valve 52 closes the second air collection inlet 43, blocking the connection between the smoking split body 3 and the air collection split body 4. The reversing valve 50 closes the reversing air outlet 20, blocking the connection between the first and second heat exchange split bodies 1 and 2. When the first fan 22 is running, outdoor air enters the second heat exchange split body 2 through the second air inlet 23, and flows out from the second air outlet 24 under the guidance of the first fan 22, introducing outdoor fresh air into the room, improving air circulation, and generating the second fresh air mode of fresh air.

[0136] like Fig. 9As shown, the second air inlet 23 exchanges air with the outside. In the third smoke removal mode, the first control valve 51 closes the first air collection inlet 42, blocking the connection between the first heat exchange split 1 and the air collection split 4. The second control valve 52 opens the second air collection inlet 43, connecting the smoking split 3 and the air collection split 4. The reversing valve 50 closes the reversing air outlet 20, blocking the connection between the first and second heat exchange splits 1 and 2. When the second fan 41 is running, the indoor air enters the smoking split 3 through the smoking port 31, and flows to the air collection split 4 under the action of the second fan 41. Because the air collection split 4 is blocked from connecting with the first heat exchange split 1, the indoor air flows to the air collection outlet 44 under the action of the second fan 41, and is discharged from the flue 71. When the first fan 22 is running, the outdoor air enters the second heat exchange split 2 through the second air inlet 23, and flows out from the second air outlet 24 under the guidance of the first fan 22, introducing the outdoor air into the room. When the smoking split unit 3 is in operation, it removes indoor gas and introduces fresh air from the outside to increase the indoor air circulation speed.

[0137] Furthermore, when the second air inlet 23 inhales air from the room, the kitchen air treatment system 100 has a fourth smoke removal mode. In the fourth smoke removal mode, the first control valve 51 opens the first air collection inlet 42, the second control valve 52 opens the second air collection inlet 43, the reversing valve 50 opens the reversing air port 20, and both the first fan 22 and the second fan 41 are in operation.

[0138] like Fig.10 As shown, the second air inlet 23 sucks air from the room. In the fourth smoke removal mode, the first control valve 51 opens the first air collection inlet 42 to connect the first heat exchange split body 1 and the air collection split body 4. The second control valve 52 opens the second air collection inlet 43 to connect the smoking split body 3 and the air collection split body 4. The reversing valve 50 opens the reversing air port 20 to connect the first and second heat exchange split bodies 1 and 2. When the second fan 41 is running, the indoor gas enters the smoking split body 3 through the smoking port 31, flows to the air collection split body 4 under the action of the second fan 41, flows to the air collection outlet 44 under the action of the second fan 41, and is discharged from the flue 71. When the first fan 22 is running, the indoor gas enters the second heat exchange split body 2 through the second air inlet 23, can enter the first heat exchange split body 1 through the reversing air port 20, and then enter the air collection split body 4, and flows to the air collection outlet 44 under the action of the second fan 41, and is discharged from the flue 71. The second air inlet 23 increases the function of smoking indoor gas, assisting the smoking split body 3. The smoke not sucked by the smoking split body 3 will escape into the room, and the second air inlet 23 can purify the indoor air twice to improve the cleanliness of the room.

[0139] Optionally, when the second air inlet 23 inhales air from the room, and the second air inlet 23 is correspondingly provided with a first purification component 231, the kitchen air treatment system 100 has: a purification mode. In the purification mode, the first control valve 51 closes the first air collection inlet 42, the second control valve 52 closes the second air collection inlet 43, the reversing valve 50 closes the reversing air port 20, and the first fan 22 runs.

[0140] like Fig.11 As shown, the second air inlet 23 sucks air from the room. In the purification mode, the first control valve 51 closes the first air collection inlet 42, blocking the connection between the first heat exchange split body 1 and the air collection split body 4. The second control valve 52 closes the second air collection inlet 43, blocking the connection between the smoking split body 3 and the air collection split body 4. The reversing valve 50 closes the reversing air outlet 20, blocking the connection between the first and second heat exchange split bodies 1 and 2. When the first fan 22 is running, when the indoor air passes through the second air inlet 23, the first purification element 231 purifies the airflow passing through. The purified air flows out through the second air outlet 24 and flows into the room. The indoor air passes through the first purification element 231 to remove dust and other impurities. The purified airflow flows into the room again, circulates and purifies the indoor air, and improves the indoor air quality.

[0141] Specifically, the first purification element 231 is installed in a detachable connection manner. After such an arrangement, the user can install it on the second heat exchange split body 2 according to needs, or remove it from the second heat exchange split body 2 and clean or replace it.

The first fan 22 is running, sucking air from the first air inlet 12, the second heat exchanger 21 is refrigerated, and the air is dehumidified through the second heat exchanger 21. The humid air is cooled and liquefied when passing through the second heat exchanger 21, and the water vapor in the air is removed. The dehumidified airflow flows into the room from the second air outlet 24 under the guidance of the first fan 22, and performs the dehumidification function on the indoor air. The first heat exchanger 11 connected to the second heat exchanger through the compressor 10 will heat when the second heat exchanger 21 is cooling. The second fan 41 is running, and the first air inlet 12 connected to the outside transports the outdoor air into the first heat exchange split body 1.
