In addition, the features defined as "first" and "second" can be explicitly or implicitly included one or more of the features. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0056] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0057] The following will be described with reference to Figures 1-14 A kitchen air conditioning system 1000 according to an embodiment of the present application is described.

[0058] As Figures 1-3 , Figure 8 As shown in the drawings, the kitchen air conditioning system 1000 according to the present application includes an air conditioning main machine 100, a range hood main machine 200, an air conditioning blowing fan 71 and an exhaust fan 300. The kitchen air conditioning system 1000 can be independently applied in a kitchen, the air conditioning main machine 100 has a refrigeration and / or heating function, and can be used to change the ambient temperature in the kitchen, while the range hood main machine 200 is used to suck the oil smoke generated in the kitchen during cooking, the air conditioning blowing fan 71 is used to drive the air in the air conditioning main machine 100 to blow into the kitchen, and the exhaust fan 300 can guide the oil smoke sucked by the range hood to the outside, providing negative pressure for the range hood to suck the oil smoke, and the exhaust fan 300 can also drive the airflow to be discharged outside after heat exchange with the air conditioning main machine 100.

[0059] In the related art, the air conditioner in the kitchen has low integration, and has many parts. The range hood and the air conditioner both need to guide the airflow, but cannot share the same fan. Meanwhile, the air outlet position of the air conditioner is limited, and the air outlet position is far from the user's position during cooking, which cannot guarantee the environment temperature for the user during cooking in the kitchen. To solve this problem, the kitchen air conditioning system 1000 provided by the scheme of the present application highly integrates the air conditioner host 100 and the range hood host 200.

[0060] As shown in Figure 6 , Figure 8 and Figure 10 , the air conditioner host 100 includes a first casing 10, a first heat exchanger 20, and a second heat exchanger 30. The first casing 10 defines a first heat exchange chamber 11 and a second heat exchange chamber 12. The first heat exchanger 20 is arranged in the first heat exchange chamber 11 and is adapted to exchange heat with the airflow flowing through the first heat exchange chamber 11. The second heat exchanger 30 is arranged in the second heat exchange chamber 12 and is adapted to exchange heat with the airflow flowing through the second heat exchange chamber 12. The first heat exchanger 20 and the second heat exchanger 30 can be connected by a refrigerant pipeline, and a compressor 40 and other components such as a throttling device are arranged on the refrigerant pipeline to enable the first heat exchanger 20 and the second heat exchanger 30 to complete the Carnot cycle. Here, the compressor 40, the first heat exchanger 20, the second heat exchanger 30, 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, for example, the first heat exchanger 20 can only absorb heat when the compressor 40 is operating. The refrigerant flow direction of the heat pump circulation system can also be variable, for example, the refrigerant flow directions in the first heat exchanger 20 are opposite during cooling and heating. According to user needs, other components such as a three-way valve, a filter, and a liquid tank can also be arranged on the heat pump circulation system, which is not limited here.

[0061] Referring to Figure 8 , the first heat exchange chamber 11 has a first return air inlet 11a and a first air outlet 11b. The first return air inlet 11a can intake air from indoors or outdoors, and the first air outlet 11b is used to discharge air to the kitchen. An air blowing fan 71 is used to drive the air in the first heat exchange chamber 11 to flow towards the first air outlet 11b.

[0062] The second heat exchange chamber 12 has a second return air inlet 12a, a second air outlet 12b, and a smoke interface 12c. The second return air inlet 12a can intake air from indoors or outdoors, and the smoke interface 12c is used to introduce flue gas. The second air outlet 12b is in communication with the outside, and an exhaust fan 300 is used to drive the airflow in the second heat exchange chamber 12 to flow towards the second air outlet 12b.

[0063] The first casing 10 of the air conditioner main unit 100 integrates the first heat exchanger 20 and the second heat exchanger 30, improves the integration of the air conditioner main unit 100, does not need to set the air conditioner outdoor unit, and does not need to set the outdoor unit installation position outdoors, reduces the number of parts of the kitchen air conditioner system 1000, and makes the installation of the kitchen air conditioner system 1000 more simple and convenient.

[0064] As shown in Figures 11-14 , the extractor hood main unit 200 includes a second casing 210 and an oil filtering piece 220. The second casing 210 is provided with an oil fume passage 211, and the oil fume passage 211 has an oil fume inlet 211a and a flue outlet 211b. The oil fume inlet 211a and the flue outlet 211b are both formed on the second casing 210. The oil filtering piece 220 is arranged in the oil fume passage 211, for example, the oil filtering piece 220 can be arranged at the oil fume inlet 211a of the oil fume passage 211, or arranged on the inner wall of the oil fume passage 211. In some schemes, the oil filtering piece 220 can be multiple, for example, a condensing plate is arranged at the oil fume inlet 211a as the first oil filtering piece 220, and a filter mesh is arranged around the condensing plate as the first oil filtering piece 220. In some schemes, when the filter mesh is arranged, a single layer or multiple layers can be arranged. In some schemes, the oil filtering piece 220 includes a filtering piece arranged on the inner wall of the oil fume passage 211, such as various carbon particles.

[0065] Referring to Figures 1-3 , the second casing 210 is connected with the first casing 10, and the flue outlet 211b communicates with the oil fume interface 12c. When the exhaust fan 300 is running, the airflow in the oil fume passage 211 can be driven to flow towards the second air outlet 12b.

[0066] That is, the exhaust fan 300 can act on the extractor hood main unit 200 and the air conditioner main unit 100 at the same time, and respectively provide power for the airflow flowing in the oil fume passage 211 and the second heat exchange chamber 12. The exhaust fan 300 can selectively serve the extractor hood main unit 200 or the air conditioner main unit 100. The arrangement of the exhaust fan 300 makes the gas after heat exchange in the second heat exchange chamber 12 and the flue gas after filtering treatment in the oil fume passage 211 all driven by the exhaust fan 300 to flow and discharge towards the outdoor. After such arrangement, the discharge of the two gas streams can be arranged in the same pipeline system, for example, in Figures 1-3 , the second air outlet 12b is connected with an exhaust pipeline 902, the number of pipelines is reduced, the pipeline is shortened, and the structural occupied volume and the pipeline layout difficulty can be greatly reduced.

[0067] In the scheme of the present application, the exhaust fan 300 can drive the flue gas flow in the oil fume passage 211 and also can drive the air flow in the second heat exchange chamber 12, so the exhaust fan 300 is used for two purposes. In some schemes, multiple use modes can be set according to the needs, for example, the communication of the exhaust fan 300 with the oil fume passage 211 and the second heat exchange chamber 12 can only be in the mode of two choices, when the exhaust fan 300 communicates with the oil fume passage 211, the flow communication between the exhaust fan 300 and the second heat exchange chamber 12 is disconnected; when the exhaust fan 300 communicates with the second heat exchange chamber 12, the flow communication between the exhaust fan 300 and the oil fume passage 211 is completely disconnected, so that the heat exchange and the oil fume extraction can be carried out separately.

[0068] In some schemes, the exhaust fan 300 inhales gas from the oil fume passage 211 and the second heat exchange chamber 12 at the same time when the exhaust fan 300 operates, so that the heat exchange and the oil fume extraction can be carried out simultaneously. In some schemes, the kitchen air conditioning system 1000 further includes a proportional adjusting device for adjusting the proportion of the gas inhaled from the oil fume passage 211 and the second heat exchange chamber 12 when the exhaust fan 300 operates, so that the kitchen air conditioning system 1000 can carry out the heat exchange and the oil fume extraction separately or simultaneously.

[0069] In some schemes, when the exhaust fan 300 operates, the second return air inlet 12a is opened and the oil fume inlet 211a (or the flue outlet 211b) is closed, at this time, under the action of the wind pressure, the exhaust fan 300 can only drive the air flow to be inhaled from the second return air inlet 12a and then be blown out from the second air outlet 12b. When the exhaust fan 300 operates, the second return air inlet 12a is closed and the oil fume inlet 211a (or the flue outlet 211b) is opened, at this time, under the action of the wind pressure, the exhaust fan 300 can only drive the air flow to be inhaled from the oil fume inlet 211a and then be blown out from the second air outlet 12b.

[0070] In the scheme of the present application, the first heat exchanger 20 and the second heat exchanger 30 and other parts are integrated into the air conditioning main machine 100, and then directly connected with the range hood main machine 200, without the need for connecting pipes between the two, so that the overall occupied volume can be further reduced, and because there is no need for pipe connection, the cross section of the air flow passage from the oil fume passage 211 to the second heat exchange chamber 12 does not need to change greatly, which is beneficial to reduce the pressure loss and reduce the energy consumption.

[0071] In the scheme of the present application, the communication positions of the first return air inlet 11a and the second return air inlet 12a are very flexible and can be set according to the needs.

[0072] For example, in some schemes, the first return air inlet 11a is directly connected with the kitchen, and in some schemes, the first return air inlet 11a is connected with the second return air inlet 12a. Figure 1The first return air inlet 11a is connected to the living room, and in another embodiment, the first return air inlet 11a is connected to the outside. Similarly, the second return air inlet 12a can be directly connected to the kitchen, or the second return air inlet 12a is connected to the living room, or as shown in Figure 1 The second return air inlet 12a is connected to the outside.

[0073] In the example shown in Figures 1-3 , the first return air inlet 11a is connected to the first air inlet pipe 905, and the other end of the first air inlet pipe 905 extends to the living room. The second return air inlet 12a is connected to the second air inlet pipe 906, and the other end of the second air inlet pipe 906 passes through the wall and can then absorb outdoor fresh air. Alternatively, as shown in Figure 1 , a through hole is provided in the wall, and the other end of the second air inlet pipe 906 is arranged in the through hole.

[0074] When the first air inlet pipe 905 and / or the second air inlet pipe 906 are connected to other rooms, air from the other rooms can be drawn into the air conditioner main unit 100, and air flow in the other rooms can also be promoted. At this time, the windows of the other rooms are opened, and the pressure difference causes external fresh air to be supplemented into the room, achieving ventilation of the room.

[0075] Alternatively, a filter screen can be provided at the inlet of the first air inlet pipe 905 and / or the second air inlet pipe 906 to reduce the entry of impurities such as lint into the air conditioner main unit 100.

[0076] Specifically, the second air outlet 12b is connected to the exhaust pipe 902. More specifically, the exhaust pipe 902 can be a flue in the kitchen, or a pipe connecting the second air outlet 12b to the flue in the kitchen.

[0077] For example, in Figure 1 , a flue is provided at a corner of the kitchen, and the flue is arranged vertically. One end of the exhaust pipe 902 is connected to the second air outlet 12b, and the other end is connected to the flue.

[0078] Specifically, any one of the exhaust pipe 902, the first air inlet pipe 905, and the second air inlet pipe 906 can be a hard pipe, and any one of the exhaust pipe 902, the first air inlet pipe 905, and the second air inlet pipe 906 can also be a flexible pipe (such as a bellows). When the pipe is a flexible pipe, not only can it provide an arrangement allowance, but it can also facilitate detouring obstacles.

[0079] For example, in Figure 1 , the exhaust pipe 902 is a hard pipe, and the first air inlet pipe 905 and the second air inlet pipe 906 are flexible pipes. Figure 3As shown, the first housing 10 has first return air vents 11a on at least two sides, which allows for more options in the installation position of the first air intake duct 905. For example, a first return air vent 11a that makes the first air intake duct 905 shorter can be selected during installation, and unselected first return air vents 11a can be sealed with a cover. Alternatively, the first housing 10 can connect at least two first air intake ducts 905, thereby increasing the airflow.

[0080] Similarly, as Figure 1 and Figure 3 As shown, the first housing 10 has at least two second return air vents 12a on both sides, so that at least two second return air vents 12a can be selected when the second air intake duct 906 is connected. The first housing 10 has at least two second air outlets 12b on both sides, so that at least two second air outlets 12b can be selected when the exhaust duct 902 is connected.

[0081] In this application, the first air outlet 11b can be located on the first housing 10, allowing the air conditioning unit 100 to directly blow air. The first air outlet 11b can also be positioned to blow air towards the kitchen at intervals. For example, a heat exchange duct is also provided inside the second housing 210, with an air conditioning outlet and an air conditioning inlet. Both the air conditioning outlet and inlet are located on the second housing 210, and the air conditioning inlet is connected to the first air outlet 11b. This arrangement provides greater flexibility in choosing the air conditioning outlet location; for example, it can be positioned closer to the stove, or even blow directly onto the user, effectively improving the kitchen temperature during cooking and enhancing the user's cooking comfort.

[0082] Furthermore, the air outlet position of the air conditioning unit 100 facing the room can be configured in various ways. For example, air can be supplied from the bottom of the first housing 10 or the second housing 210, or from the top of the second housing 210. In some designs, air can also be supplied from the side of the first housing 10 or the second housing 210, thereby further improving user comfort.

[0083] In some embodiments, there are multiple first air outlets 11b or air conditioning outlets, spaced apart on the first housing 10 and / or the second housing 210. This increases the airflow range and expands the area used to improve temperature. Optionally, the user can selectively choose to open different air outlets to meet their individual needs. For example, if the ambient temperature feels too high, the user can open multiple air outlets to increase airflow and quickly lower the ambient temperature. The user can choose air outlets at different heights based on their own height. The user can choose the corresponding air outlet based on the location of the stovetop where cooking is taking place to reduce the feeling of being scorched.

[0084] In some specific embodiments, an air guide plate is provided at the air outlet for adjusting the air outlet direction. Optionally, the air guide plate is rotatably connected to the housing so that it can be folded up when not in use and unfolded when in use.

[0085] Among them, such as Figure 8 As shown, the first housing 10 is provided with a blower guide plate 72, which includes a pivot portion 721 and a guide arc panel 722. The pivot portion 721 is formed on the inner side of the guide arc panel 722.

[0086] The pivot section 721 is connected to a blower angle adjustment motor (not shown in the figure). The output end of the blower angle adjustment motor drives the pivot section 721 to rotate. It should be noted that during the rotation of the pivot section 721, the rotation axis of the output shaft is in the same direction as the extension of the first air outlet 11b located on the front of the first housing 10. A guide arc panel 722 is connected to the pivot section 721. The guide arc panel 722 is constructed as an arc protruding away from the first air outlet 11b to make the appearance of the air conditioning unit 100 more rounded and beautiful. When the blower guide plate 72 is driven to rotate, at least a part of the blower guide plate 72 can rotate to be housed inside the first air outlet 11b, opening the first air outlet 11b located on the front of the first housing 10, while simultaneously hiding the blower guide plate 72.

[0087] More specifically, since the outer side of the air guide panel 722 of the air blower guide plate 72 is an arc shape protruding from the front of the first housing 10, the user can adjust the rotation angle of the air blower guide plate 72 by changing the pivot angle of the air blower guide plate 72 to adjust the air outlet area of ​​the first air outlet 11b located on the front of the first housing 10.

[0088] In some embodiments, such as Figure 8 and Figure 10 As shown, the first heat exchange chamber 11 includes a first installation chamber 115 and an air supply duct 116 connected to each other. The first heat exchanger 20 is located in the first installation chamber 115. The first return air vent 11a is connected to the first installation chamber 115, and the first air outlet 11b is connected to the air supply duct 116. The air conditioner blower 71 drives the air in the first installation chamber 115 to flow towards the air supply duct 116. The air supply duct 116 is designed so that the first return air vent 11a can be located away from the first heat exchanger 20. The air supply duct 116 lengthens the airflow distance, allowing the air that has exchanged heat with the first heat exchanger 20 to circulate sufficiently for a period of time to reach a uniform temperature before being blown out from the first air outlet 11b. Moreover, the position of the first air outlet 11b is relatively close to the area where the user is cooking.

[0089] Specifically, such as Figure 6 and Figure 8As shown, the second heat exchange chamber 12 comprises a second installation chamber 125, a smoke receiving passage 126 and a converging chamber 127, the converging chamber 127 is in communication with the second installation chamber 125 and the smoke receiving passage 126 respectively, the second heat exchanger 30 is located in the second installation chamber 125, the second air return port 12a is in communication with the second installation chamber 125, the second air outlet 12b is in communication with the converging chamber 127, the oil fume interface 12c is in communication with the smoke receiving passage 126, and the exhaust fan 300 drives the air in the second installation chamber 125 to flow towards the converging chamber 127 and drives the flue gas in the smoke receiving passage 126 to flow towards the converging chamber 127.

[0090] The above arrangement avoids the second heat exchanger 30 between the oil fume interface 12c and the converging chamber 127, so that when the flue gas flows towards the converging chamber 127, the amount of flue gas flowing towards the second heat exchanger 30 is small, reducing the pollution of the flue gas to the second heat exchanger 30, and also avoiding the flue gas from easily flowing out from the second air return port 12b after passing through the second installation chamber 125. Moreover, after the exhaust fan 300 operates, the flue gas does not flow from the second heat exchanger 30, which can reduce the influence of the flue gas on the heat exchange of the second heat exchanger 30.

[0091] Specifically, as shown, Figure 8 The air supply passage 116 is arranged side by side with the smoke receiving passage 126, so that when the first heat exchanger 20 is refrigerating, the low-temperature airflow generated by the air conditioner main unit 100 flows in the air supply passage 116, which can reduce the temperature of the wall of the smoke receiving passage 126, on the one hand, it can alleviate the aging caused by overheating, and on the other hand, it can make the oil smoke flowing in the smoke receiving passage 126 more easily condensed, thereby improving the filtering effect on the oil smoke.

[0092] As shown, Figure 8 The air conditioner partition plate 15 is arranged in the first cabinet 10 to divide the first cabinet 10 into the first heat exchange chamber 11 and the second heat exchange chamber 12. The air conditioner partition plate 15 can be arranged as a heat conduction plate between the air supply passage 116 and the smoke receiving passage 126, thereby improving the heat exchange efficiency between the air supply passage 116 and the smoke receiving passage 126.

[0093] Optionally, the air supply passage 116 and the smoke receiving passage 126 are arranged in the front-rear direction, and the air supply passage 116 is located in front of the smoke receiving passage 126, so that the air supply passage 116 is closer to the user in front of the cooking table. In this way, the air supply passage 116 can separate the heat radiated forward by the smoke receiving passage 126, thereby improving the comfort of the user.

[0094] Further, the airflow directions in the air supply passage 116 and the smoke receiving passage 126 are opposite, so that the heat exchange efficiency between them is higher. The airflow in the air supply passage 116 is sent to the user, and the smoke receiving passage 126 sends the flue gas away from the user.

[0095] In some specific embodiments, asFigure 6 and Figure 8 As shown, the exhaust fan 300 is located inside the manifold 127, and the air inlet of the exhaust fan 300 is located at the junction of the second installation chamber 125 and the smoke inlet duct 126. Placing the exhaust fan 300 in the manifold 127, very close to both the second installation chamber 125 and the smoke inlet duct 126, provides strong suction to both chambers, helping to increase airflow using a powerful driving force.

[0096] In addition, the exhaust fan 300 is located in the manifold 127. The exhaust fan 300 can also serve to block oil. When oil droplets are hung on the exhaust fan 300, they can flow along the exhaust fan 300 to the oil collection point on the range hood main unit 200, for example, they can flow into the oil collection box 272 at the bottom of the range hood main unit 200.

[0097] Furthermore, if the exhaust fan 300 is located outside the first housing 10, the exhaust fan 300 will occupy additional space. Therefore, placing the exhaust fan 300 inside the manifold 127 can make full use of the space inside the first housing 10.

[0098] Specifically, the exhaust fan 300 is a centrifugal fan. The centrifugal fan drives the airflow and flue gas. On the one hand, it has strong driving force, and on the other hand, in such a compact device, the characteristics of the centrifugal fan can be utilized to place the exhaust fan 300 at the point where the airflow needs to turn. This not only eliminates the need to set up bends to guide the airflow, but also reduces eddies and lowers wind loss.

[0099] Using centrifugal impellers for suction and blowing helps to confine the airflow within the pipes, resulting in less resistance and loss as the airflow flows through various pipes and interfaces.

[0100] Furthermore, since the airflow in the second installation chamber 125 and the airflow in the smoke inlet duct 126 come from different directions relative to the confluence chamber 127, using a centrifugal fan at this time helps to draw in airflows from different directions and then blow them out from the same direction.

[0101] like Figure 6 and Figure 8 As shown, the exhaust fan 300 has an exhaust volute 305, the inner cavity of which forms a manifold 127. This eliminates the need for a separate partition in the second heat exchange chamber 12, reducing the number of parts. Furthermore, the second heat exchange chamber 12 allows for more space to serve as a second mounting chamber 125 and a smoke inlet passage 126.

[0102] Further, the air inlet end of the exhaust fan 300 is located at the axial side of the exhaust fan 300, and the second mounting chamber 125, the smoke inlet channel 126, and the air inlet end of the exhaust fan 300 are located at the same side of the exhaust fan 300. Since the exhaust fan 300 is a centrifugal fan, the exhaust fan 300 can take in air in the axial direction and discharge air in the radial direction. The second mounting chamber 125 and the smoke inlet channel 126 are arranged at the axial side of the exhaust fan 300, which is beneficial to the flat design of the first cabinet 10 at the exhaust fan 300.

[0103] Specifically, as shown in Figure 8 , when the axis of the exhaust fan 300 is arranged in the front-rear direction, a centrifugal fan with a smaller axial size can be selected as the exhaust fan 300. At this time, the smoke inlet channel 126 located at the front side of the exhaust fan 300 can also be designed to be thinner, so that the first cabinet 10 at the smoke inlet channel 126 has a smaller size in the front-rear direction. The first cabinet 10 is connected to the second cabinet 210 at the smoke inlet channel 126, and the second cabinet 210 is also designed to be thinner without an oil extraction fan in the second cabinet 210. The second cabinet 210 and the area connected to the second cabinet 210 are also thinner. When installed, this area is directly opposite the cooking table, which can avoid occupying the cooking space, and the thinner design makes the appearance more like a decorative wall, which is more aesthetic.

[0104] In some embodiments, as shown in Figures 8-10 , the first mounting chamber 115 and the second mounting chamber 125 are arranged in the horizontal direction, the first mounting chamber 115 is located at the side of the second mounting chamber 125 away from the exhaust fan 300, and the side of the second heat exchanger 30 adjacent to the first mounting chamber 115 is provided with a heat insulation plate. In other words, at least part of the air conditioner partition plate 15 is a heat insulation plate, which can reduce the heat exchange between the first heat exchanger 20 and the second heat exchanger 30, and avoid heat short circuit to reduce the heat exchange efficiency of the air flowing through.

[0105] Here, the first mounting chamber 115 and the second mounting chamber 125 are arranged in the horizontal direction, so that the first heat exchanger 20 and the second heat exchanger 30 are generally arranged in the horizontal direction. In this way, the area of the first cabinet 10 where the first heat exchanger 20 and the second heat exchanger 30 are installed can be designed to be flat, and when the air conditioner main unit 100 is installed, this area can be placed above the cooking table. The flat design facilitates the user to hide it, for example, in Figure 1 , the area of the first cabinet 10 where the first heat exchanger 20 and the second heat exchanger 30 are installed is located above the ceiling 800, and due to the flat design, the distance between the ceiling 800 and the roof can be smaller.

[0106] Here, the first mounting chamber 115 and the exhaust fan 300 are arranged on both sides of the second mounting chamber 125, as shown in Figure 8The first installation chamber 115 is located at the front side of the second installation chamber 125 and at the rear side of the exhaust fan 300. It can be understood that, after the above arrangement, the air conditioner main unit 100 is in a right angle shape as a whole, the first installation chamber 115 and the second installation chamber 125 are located on the horizontal part, the second installation chamber 125 and the exhaust fan 300 are located on the vertical part, the second heat exchanger 30 is installed at the corner of the right angle shape, which is beneficial to improve the corner space utilization rate and thus reduce the overall occupied volume.

[0107] Specifically, after the air conditioner main unit 100 is in a right angle shape as a whole, the vertical part of the right angle shape is installed against the wall, and the horizontal part of the right angle shape is installed against the roof as much as possible, so that the air conditioner main unit 100 is installed at the corner of the kitchen as a whole. The corner is a right angle itself, and after the air conditioner main unit 100 in the right angle shape is installed, the horizontal part and the vertical part can be positioned by the corner. When the air conditioner main unit 100 is installed, the wall and the roof (or the shelf below the roof, the suspended ceiling 800, etc.) can be used for positioning, so that the air conditioner main unit 100 is installed in double-sided positioning, which not only has high positioning accuracy, but also is more firm and reliable in installation.

[0108] Further, the extractor main unit 200 is in a vertical shape as a whole, and the extractor main unit 200 is installed below the vertical part of the air conditioner main unit 100. From the appearance, the extractor main unit 200 is a downward extension of the vertical part of the air conditioner main unit 100, and the whole is still in a right angle shape. Then, the extractor main unit 200 can also be installed and positioned against the wall, further improving the installation reliability.

[0109] Advantageously, the horizontal part of the air conditioner main unit 100 is provided with an ear, and the ear is provided with an installation hole. The ear can be fixed on the roof or the shelf below the roof or the suspended ceiling 800. The vertical part of the air conditioner main unit 100 and the back of the extractor main unit 200 can be fixed and connected to the wall.

[0110] In the scheme of the present application, the first heat exchange chamber 11 can be provided with an air conditioner blowing fan 71. When the air conditioner blowing fan 71 operates, air is sucked from the first air return port 11a and blown out from the first air outlet port 11b.

[0111] Specifically, as shown in Figure 8 and Figure 10 , the air conditioner blowing fan 71 is arranged in the first installation chamber 115. The air conditioner blowing fan 71 is a centrifugal fan, and the axis of the air conditioner blowing fan 71 is arranged vertically. The air outlet end of the air conditioner blowing fan 71 is connected to the air supply channel 116. In this way, a centrifugal fan with a smaller axial dimension can be selected as the air conditioner blowing fan 71, which is helpful to flatten the first installation chamber 115.

[0112] In some specific embodiments, as shown in Figure 8As shown, the second installation chamber 125 is arranged in parallel with the front side of the confluence chamber 127, and the smoke inlet channel 126 is arranged below the second installation chamber 125. In this way, the second installation chamber 125, the smoke inlet channel 126, and the confluence chamber 127 are compact, and the smoke inlet channel 126 can be conveniently connected to the main body 200 of the range hood.

[0113] Specifically, the second heat exchanger 30 is a straight-plate heat exchanger, the second heat exchanger 30 is connected to the rear wall 18 of the second installation chamber 125, the front wall 17 of the second installation chamber 125 is spaced apart from the second heat exchanger 30, and the front wall 17 of the second installation chamber 125 is in contact with the second heat exchanger 30 at the bottom. In this way, the second heat exchange chamber 12 is flattened, and the heat exchange efficiency of air and the second heat exchanger 30 is improved.

[0114] Specifically, the front wall 17 of the second installation chamber 125 is spaced apart from the second heat exchanger 30, so that the airflow flowing from the second air return port 12a can quickly fill the space between the front wall 17 and the second heat exchanger 30. The airflow finds gaps from various parts of the second heat exchanger 30 and passes through the second heat exchanger 30, and the front wall 17 in contact with the second heat exchanger 30 at the bottom can intercept the unheated air, thereby achieving full heat exchange of the airflow and the second heat exchanger.

[0115] As shown in FIG. 1, Figure 10 the rear wall 18 of the second installation chamber 125 is deformed towards the direction away from the second installation chamber 125, and as shown in FIG. 2, Figure 10 the rear wall 18 corresponding to the second heat exchanger 30 is recessed rearward to form a rear recessed cavity 1251. The rear recessed cavity 1251 allows the airflow to pass through the second heat exchanger 30 along the thickness direction of the second heat exchanger 30, and the air can contact more surfaces of the second heat exchanger 30. Moreover, the airflow can continue to exchange heat with the second heat exchanger 30 at the rear recessed cavity 1251 after passing through the second heat exchanger 30, thereby fully utilizing the heat exchange capacity of the second heat exchanger 30.

[0116] Optionally, as shown in FIG. 1, Figure 10 both ends of the second heat exchanger 30 are connected with the second side plates 31, and the second heat exchanger 30 is connected to the rear wall 18 of the second installation chamber 125 through the second side plates 31 at both ends. The second side plates 31 can reduce the leakage of the airflow from both ends of the second heat exchanger 30, and drive the airflow to flow more from the second heat exchanger 30.

[0117] In some embodiments, as shown in FIG. 1, Figure 8As shown, the front wall 17 of the second installation chamber 125 comprises a front vertical wall 171 and a front inclined wall 172 connected below the front vertical wall 171, the front inclined wall 172 extends backwardly in a downward direction, and the bottom of the front inclined wall 172 is in contact with the second heat exchanger 30. In this way, when the air flow flows downwardly in the second installation chamber 125, the air flow is guided by the front inclined wall 172 to flow toward the second heat exchanger 30.

[0118] Specifically, the front inclined wall 172 is located at the intersection of the horizontal portion and the vertical portion of the air conditioner main unit 100, and the inclined front inclined wall 172 at this position helps to improve the structural rigidity of the connection position.

[0119] In some embodiments, as shown in the drawings, Figure 6 As shown, the second heat exchange chamber 12 further comprises a flow diversion channel 128, the air flow in the flow confluence chamber 127 flows toward the flow diversion channel 128, and the air flow in the flow diversion channel 128 flows toward the second air outlet 12b. The provision of the flow diversion channel 128 can facilitate the diversion of the air flow in the flow confluence chamber 127 when the air flow flows out toward the second air outlet 12b.

[0120] Specifically, the flow diversion channel 128 is provided with the second air outlet 12b at both ends, and the air flow in the flow confluence chamber 127 can flow toward both ends after entering the flow diversion channel 128. When only one end is needed to flow out, the second air outlet 12b at the other end can be plugged.

[0121] Specifically, the bottom wall of the flow diversion channel 128 is provided with an opening to communicate with the flow confluence chamber 127.

[0122] Further, as shown in the drawings, Figure 6 Specifically, the flow diversion channel 128 is in a strip shape, and the flow diversion channel 128 comprises a flow diversion middle section 1281 and a flow diversion expanding section 1282, the flow area of the flow diversion expanding section 1282 gradually increases in the direction from the flow diversion middle section 1281 to the second air outlet 12b. In this way, the flow area of the flow diversion expanding section 1282 gradually changes to be equal to that of the second air outlet 12b, thereby facilitating the smooth flow of the air flow.

[0123] Advantageously, the flow diversion expanding section 1282 is two, and the two flow diversion expanding sections 1282 are connected at both ends of the flow diversion middle section 1281.

[0124] Optionally, the top walls of the flow diversion middle section 1281 and the flow diversion expanding section 1282 are flush, and the bottom wall of the flow diversion expanding section 1282 is formed as an inclined wall extending downwardly in a direction away from the flow diversion middle section 1281. In this way, the space in the middle of the second heat exchange chamber 12 can be left for the flow confluence chamber 127 while the space on both sides of the second heat exchange chamber 12 is fully utilized.

[0125] Further, as shown in the drawings, Figure 6As shown, the second heat exchange chamber 12 is provided with a compressor 40, and the compressor 40 is vertically arranged, so that the space in the second heat exchange chamber 12 can be fully utilized, and the system occupies a small space. As shown in Figure 6 As shown, the compressor 40 is located on the horizontal side of the exhaust fan 300, and the airflow resistance generated by the compressor 40 is small.

[0126] In Figure 6 some embodiments, the turning flow channel 128 is located above the exhaust fan 300 and the compressor 40, and one turning and expanding section 1282 corresponds to the right side of the exhaust fan 300, and the other corresponds to the left side of the compressor 40, so that the expanding section can utilize the space on both sides of the exhaust fan 300 and the compressor 40, and the structure is compactly arranged.

[0127] In some embodiments, as shown in Figure 8 , the air supply channel 116 shares the front wall 17 with the second mounting chamber 125, and the air supply channel 116 includes an air supply upper section 1161, an air supply turning section 1162, and an air supply lower section 1163. The air supply upper section 1161 is located on the front side of the front vertical wall 171, the air supply turning section 1162 is located on the front side of the front inclined wall 172, and the air supply lower section 1163 is located on the front side of the smoke inlet channel 126.

[0128] The air supply channel 116 is arranged in three sections, and the air supply upper section 1161 can be arranged at the same horizontal level as the first mounting chamber 115, so that the airflow can be directly blown into the air supply upper section 1161 after being fully exchanged with the first heat exchanger 20. Then the airflow is turned by the air supply turning section 1162, flows to the air supply lower section 1163, and flows to the first air outlet 11b from the air supply lower section 1163. Here, the air supply lower section 1163 is vertically arranged, which is beneficial to the flattening of this part and reduces the space occupied above the cooking table.

[0129] The air supply turning section 1162 is located on the front side of the front inclined wall 172, so that the airflow can be guided to the air supply lower section 1163 by the inclination of the front inclined wall 172.

[0130] Further, as shown in Figure 8 , the front side of the air supply turning section 1162 is also an inclined wall, so that the air supply turning section 1162 is an inclined channel as a whole, which is beneficial to the turning of the airflow and reduces the wind pressure loss of the airflow turning.

[0131] In some embodiments, as shown in Figure 8 and Figure 10 , the air conditioner blowing fan 71 is arranged in the first heat exchange chamber 11, and the first heat exchanger 20 surrounds at least two sides of the air conditioner blowing fan 71. In this way, the first heat exchanger 20 is unfolded in the first heat exchange chamber 11, which is beneficial to the heat exchange between the airflow and the first heat exchange chamber 11.

[0132] Specifically, the first heat exchanger 20 is connected to the first side plate 21 at both ends, and the first side plate 21 on both sides is connected to the inner wall of the first installation chamber 115, thereby reducing the flow of air from the edge of the first heat exchanger 20 and allowing more air to pass through the first heat exchanger 20 for heat exchange.

[0133] Advantageously, the first heat exchanger 20 is spaced apart from the inner wall of the first mounting chamber 115, so that the airflow can be fully dispersed in the cavity between the first heat exchanger 20 and the first return air inlet 11a before passing through the first heat exchanger 20. This arrangement allows the airflow to pass over the entire surface of the first heat exchanger 20, thereby improving the heat exchange effect.

[0134] Optionally, an electrical control box 60 is provided in the first heat exchange chamber 11. The electrical control box 60 is located on the horizontal side of the first heat exchanger 20. This can make full use of the space of the first heat exchange chamber 11 and avoid the first heat exchange chamber 11 being too high.

[0135] exist Figure 10 In the example, first return air inlets 11a are provided on both adjacent sides of the first heat exchange chamber 11, and the first heat exchanger 20 is provided corresponding to the first return air inlets 11a on both sides. The first heat exchanger 20 is L-shaped. Specifically, an L-shaped air equalization chamber is formed between the L-shaped first heat exchanger 20 and the inner wall of the first heat exchange chamber 11. After the airflow drawn in from the first return air inlets 11a enters the air equalization chamber, it can be distributed relatively evenly. Then, the airflow passes through all parts of the L-shaped first heat exchanger 20, thereby ensuring comprehensive heat exchange with the first heat exchanger 20. Figure 10 In the first heat exchanger 20, which is L-shaped, it occupies both sides of the first heat exchange chamber 11. An electrical control box 60 is located on one side of the first heat exchange chamber 11, and an air supply duct 116 is located on the other side. An air conditioning blower 71 is positioned between the first heat exchanger 20, the electrical control box 60, and the air supply duct 116. Specifically, the air conditioning blower 71 is a centrifugal fan with a volute housing inside. The volute housing has a vertically oriented axis, and an opening is formed at one axial end (the upper end), allowing the centrifugal fan to draw air from all four sides. The outlet end of the volute housing connects to the air supply duct 116, thus changing the airflow direction.

[0136] In some embodiments, the first return air inlet 11a may be provided with a first valve for opening or closing. The first valve on the first return air inlet 11a can control the opening and closing of the first return air inlet 11a.

[0137] Optionally, the second return air inlet 12a may be provided with a second valve for opening or closing. The second valve on the second return air inlet 12a can control the opening and closing of the second return air inlet 12a.

[0138] Specifically, each valve is driven by a valve motor, which improves control reliability.

[0139] Optionally, a condensate water discharge port is arranged on the first casing 10 for discharging condensate water. Optionally, a condensate water discharge port is arranged on the first heat exchange chamber 11 so that condensate water can be discharged when the air conditioner main unit 100 is cooling. In some embodiments, a condensate water discharge port is arranged on the second heat exchange chamber 12 so that condensate water can be discharged when the air conditioner main unit 100 is heating.

[0140] Further optionally, a plurality of feet 50 are arranged on the bottom wall of the first casing 10, and the feet 50 are used to connect the ceiling 800 to fix the first casing 10 on the ceiling 800. For example, the feet 50 are arranged at the four corners of the first casing 10 to improve the stability of the connection.

[0141] As shown in Figure 1 , the air conditioner main unit 100 is installed above the ceiling 800, so that the ceiling 800 can be used to hide the air conditioner main unit 100. Specifically, the pipelines connected to the air conditioner main unit 100 are also installed above the ceiling 800, which not only improves the aesthetics, but also facilitates installation and fixation using the ceiling 800.

[0142] Optionally, the ceiling 800 is made of aluminum panels, which are not only light and easy to clean. Specifically, the ceiling 800 includes a plurality of rows and columns of aluminum panels, adjacent aluminum panels are connected by splicing, and the air conditioner main unit 100 is fixed on the plurality of aluminum panels, and the air conditioner main unit 100 is connected to the splicing position of adjacent aluminum panels by a hanging ear.

[0143] In some embodiments, the oil fume interface 12c is arranged at the bottom of the first casing 10, as shown in Figure 11 , the flue outlet 211b is arranged at the top of the second casing 210, as shown in Figure 1 , the second casing 210 is connected to the bottom of the first casing 10. In this way, the oil fume interface 12c and the flue outlet 211b can be arranged in a larger area, and the airflow circulation is smoother. Moreover, the connection is convenient.

[0144] Specifically, as shown in Figure 13 and Figure 14 , the second casing 210 is provided with a sealing coaming 215, which surrounds the outside of the flue outlet 211b, thereby improving the sealing performance and reducing the leakage of flue gas.

[0145] Optionally, the sealing coaming 215 is three sections, which are arranged in front of, left side of, and right side of the flue outlet 211b, respectively, and the back side of the sealing coaming 215 is connected to the wall surface, thereby saving materials.

[0146] Further, the sealing coaming 215 is spaced apart from the side wall of the flue outlet 211b, and a smoke separation groove 216 is formed between the sealing coaming 215 and the side wall of the flue outlet 211b, which can store smoke, so that the leaked flue gas is temporarily stored in the smoke separation groove 216.

[0147] In some embodiments, the oil fume inlet 211a is arranged at the bottom of the smoke machine main body 200, so as to be close to the cooking table, and to facilitate the timely suction of more oil fume into the oil fume channel 211.

[0148] Here, the shape of the smoke machine main body 200 can refer to the shape of the existing smoke exhaust machine, and can adopt the shape of a near-suction type smoke exhaust machine or a top-suction type smoke exhaust machine. In some schemes, the bottom of the smoke machine main body 200 is also provided with a smoke collecting hood, and the oil fume inlet 211a is located at the bottom of the smoke collecting hood, so as to moderately increase the area of the negative pressure zone and increase the suction range. Of course, in some schemes, the oil fume inlet 211a can also be arranged on the front side and left and right sides of the smoke machine main body 200 to further increase the suction range.

[0149] Specifically, as shown in Figure 2 , the first casing 10 and the second casing 210 have equal widths, so that they are easy to install when connected, and can be regarded as a whole in appearance, and the connection is not conspicuous and more beautiful.

[0150] Specifically, the oil filter 220 is an oil filter grid, which can be one layer or multiple layers, which is not limited here.

[0151] In some embodiments, as shown in Figure 1 , the smoke machine main body 200 is mainly arranged below the ceiling 800 of the kitchen, and the top of the smoke machine main body 200 extends to the ceiling 800. The flue outlet 211b is located at the top of the smoke machine main body 200, so as to be convenient for connection with other structures, and the connection can be hidden by the ceiling 800.

[0152] In some embodiments, the kitchen air conditioning system 1000 further comprises a switch panel assembly 271 for adjusting the size of the oil fume inlet 211a, and the switch panel assembly 271 is movably arranged on the second casing 210. The switch panel assembly 271 can be arranged on the front side of the second casing 210, and the front side of the second casing 210 is provided with the oil fume inlet 211a. The oil fume inlet 211a is arranged on the lower side of the front panel of the second casing 210, and the oil fume inlet 211a can include a plurality of long strip holes penetrating the front panel of the second casing 210, wherein each long strip hole extends in the height direction and is arranged in the width direction of the front panel of the second casing 210.

[0153] Optionally, the switch panel assembly 271 can be rotatably or liftable arranged on the second casing 210, and the switch panel assembly 271 has an open state and a closed state. When the switch panel assembly 271 is in the closed state, the switch panel assembly 271 covers the front surface of the second casing 210, thereby covering the oil fume inlet 211a on the front surface of the second casing 210, and only keeping the oil fume inlet 211a on the lower end surface of the second casing 210 conductive. When the switch panel assembly 271 is in the closed state, it can be adapted to a state with less oil fume, and the switch panel assembly 271 kept in the closed state can reduce the space occupied by the range hood main machine 200.

[0154] Optionally, as shown in Figure 13 , the inner side of the switch panel assembly 271 is connected with a shaft plate 2714, and the switch motor is connected with the shaft plate 2714 to drive the whole switch panel assembly 271 to rotate.

[0155] In an embodiment of the present application, the opening and closing of the switch panel assembly 271 can be set by the user or automatically opened by the sensor detecting that the amount of oil fume exceeds the preset value, and the opening mode of the switch panel assembly 271 can also be a combination of the above two modes, and the priority of the user's manual setting is higher than that of the automatic detection. The automation degree of the kitchen air conditioning system 1000 can be further improved.

[0156] In some embodiments, as shown in Figure 12 , Figure 13 , the lower side of the second casing 210 is further provided with an oil collecting box 272, and the lower end of the second casing 210 can be configured as a trapezoidal structure, and the thickness of the trapezoidal structure gradually decreases in the direction extending towards the lower side, wherein the front side of the trapezoidal structure is provided with the oil fume inlet 211a which is not shielded by the switch panel assembly 271, and this part of the oil fume inlet 211a is arranged on the front side of the trapezoidal structure, and the front side of the trapezoidal structure is a slope, and arranging this part of the oil fume inlet 211a on the slope can increase the cross-sectional area of this part of the oil fume inlet 211a, thereby having sufficient capacity to absorb oil fume when the switch panel assembly 271 is not opened.

[0157] Further, configuring the lower end of the second casing 210 as a trapezoidal structure can facilitate the oil fume flowing through the oil fume inlet 211a, and the oil fume flows to the oil collecting box 272 arranged on the bottom surface of the trapezoidal structure under the action of gravity. At the same time, the upper end of the oil collecting box 272 is formed with an oil collecting box opening, the width of the oil collecting box opening is greater than the width of the ground of the trapezoidal structure, and at least part of the oil collecting box opening is opposite to the oil fume inlet 211a in the height direction. To ensure that the oil fume filtered by the oil fume inlet 211a located on the front side of the trapezoidal structure can fall into the oil collecting box 272, and avoid the oil fume dropping on the countertop.

[0158] In some embodiments, the first air outlet 11b is located above the oil fume inlet 211a, and the second cabinet 210 is provided with a switch panel assembly 271 for adjusting the size of the oil fume inlet 211a, and the switch panel assembly 271 is rotatably connected to the front side of the second cabinet 210. In this way, when the switch panel assembly 271 is opened, the switch panel assembly 271 can effectively separate the air-conditioning air blown outward and the fumes sucked inward, and the air-conditioning air above the switch panel assembly 271 can be directly guided to the area where the user is located.

[0159] Optionally, the range hood main machine 200 is also provided with an operation panel 273 for the convenience of user operation. Further optionally, the operation panel 273 is arranged on the front panel of the second cabinet 210. Of course, in some schemes, it can also be arranged on the left side panel or the right side panel of the second cabinet 210, or even arranged on the wall as a separate part.

[0160] Further optionally, the range hood main machine 200 is fixed to the wall through the second cabinet 210, for example, the back panel of the second cabinet 210 is provided with a wall hanging panel to be hung on the wall.

[0161] In some embodiments, the kitchen air conditioning system 1000 further comprises a return air assembly installed on the ceiling 800 of the kitchen, and the air in the kitchen flows to the first return air inlet 11a through the return air assembly. The return air assembly can guide the airflow in the kitchen to the ceiling 800, and the return air assembly connects the lower part of the ceiling 800 with the upper part of the ceiling 800, so that the airflow in the lower part of the ceiling 800 enters the upper part of the ceiling 800 through the return air assembly, and the first return air inlet 11a is open above the ceiling 800, so that the airflow in the upper part of the ceiling 800 can enter the first return air inlet 11a and then exchange heat with the corresponding heat exchanger to realize the refrigeration or heating function of the air conditioning main machine 100. By arranging the return air assembly on the ceiling 800, the return air arrangement of the air conditioning main machine 100 is simplified. In some schemes, the airflow in the upper part of the ceiling 800 can enter the second return air inlet 12a.

[0162] Optionally, the return air assembly comprises a face frame and a panel grille, the face frame is suitable for being fixed on the ceiling 800 of the kitchen, and the panel grille is detachably installed on the face frame. The ceiling 800 can be provided with a return air assembly mounting hole, and the face frame can be fixed on the return air assembly mounting hole. The face frame serves as the installation basis of the panel grille, and the panel grille is detachably arranged on the face frame to facilitate subsequent cleaning and maintenance of the panel grille.

[0163] In the scheme of the present application, the kitchen air conditioning system 1000 at least has a refrigeration mode and an oil fume extraction mode.

[0164] In the cooling mode, the compressor 40, the air conditioner blowing fan 71 and the exhaust fan 300 are all in operation. The compressor 40 is in operation to make the first heat exchanger 20 cool, while the second heat exchanger 30 is in operation to heat. The air conditioner blowing fan 71 is in operation to suck air from the first air return port 11a into the first heat exchange chamber 11, and the sucked air flows through the first heat exchanger 20 to be cooled, and the low-temperature air is blown out from the first air outlet 11b. The exhaust fan 300 is in operation to suck air from the second air return port 12a into the second heat exchange chamber 12, and the sucked air flows through the second heat exchanger 30 to be heated, and the high-temperature air can be exhausted from the exhaust duct 902. In this mode, if the oil fume passage 211 is open, the exhaust fan 300 also sucks air from the oil fume inlet 211a. If the oil fume passage 211 is not open, the exhaust fan 300 only sucks air from the second air return port 12a.

[0165] In the oil fume extraction mode, the exhaust fan 300 is in operation to suck oil fume from the oil fume inlet 211a into the oil fume passage 211, and then exhaust the oil fume through the exhaust duct 902.

[0166] In some schemes, the cooling mode and the oil fume extraction mode can be performed simultaneously, in which the compressor 40 is in operation, and the air conditioner blowing fan 71 and the exhaust fan 300 are both in operation.

[0167] Of course, when the above components have other forms, the kitchen air conditioning system 1000 can also have more modes, or combinations of more modes. In some schemes, the kitchen air conditioning system 1000 also has a heating mode, a dehumidification mode, etc., which will not be described here.
