[0006] According to the present invention, a kitchen air conditioning system is provided with an air conditioner main unit and a range hood main unit. The range hood main unit is provided with a heat exchange duct connected to the air conditioning outlet of the air conditioner main unit. The range hood main unit directs the heat exchanged airflow into the kitchen. The range hood main unit integrates the dual functions of extracting cooking fumes and discharging the heat exchanged airflow, effectively improving the ambient temperature for users during cooking. The kitchen air conditioning system has a high degree of integration, a small number of components, and a simple and convenient layout. Furthermore, the provision of a fresh air vent and a fresh air switch assembly allows the first and second heat exchange chambers to share fresh air from the fresh air duct. The first heat exchange chamber can operate in fresh air mode without requiring a separate heightened fresh air duct, and even allows the kitchen air conditioning system to operate in both fresh air and range hood extraction modes simultaneously. When both modes are in operation simultaneously, fresh air is continuously replenished, while indoor cooking fumes are continuously drawn into the fume inlet.

[0055] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0057] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0058] Reference below Figures 1-19 A kitchen air conditioning system 1000 according to an embodiment of the present invention is described.

[0059] like Figure 1-Figure 3As shown, the kitchen air conditioning system 1000 according to the present invention includes an air conditioner main unit 100, a range hood main unit 200, and an exhaust fan 300. The kitchen air conditioning system 1000 according to the present invention can be used independently in the kitchen. The air conditioner main unit 100 has cooling and / or heating functions and can be used to change the ambient temperature in the kitchen. The range hood main unit 200 is used to extract cooking fumes in the kitchen, and the exhaust fan 300 guides the fumes sucked by the range hood to provide negative pressure for the fumes to be extracted by the range hood.

[0060] In the related art, kitchen air conditioners have low integration and a large number of components. Both the range hood and the air conditioner need to direct the airflow, but they cannot share the same fan. At the same time, the air outlet position of the air conditioner is very limited, and the air outlet position is far away from the user's position when cooking, which cannot guarantee the ambient temperature when the user is cooking in the kitchen. In addition, some oil smoke will always remain in the kitchen after long-term use. If a ventilation device is installed to introduce fresh air from outside into the kitchen, it will take up a part of the space, and the overall pipe connection will be complicated and troublesome. To solve this problem, the solution of this application proposes a kitchen air conditioning system 1000, in which the air conditioner main unit 100 and the range hood main unit 200 are highly integrated in structure and can also perform fresh air ventilation.

[0061] like Figure 4-6 As shown, in the kitchen air conditioning system 1000 according to the present invention, the air conditioning 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 suitable for exchanging heat with the air flow flowing through the first heat exchange chamber 11. The second heat exchanger 30 is arranged in the second heat exchange chamber 12 and is suitable for exchanging heat with the air flow 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. A compressor 40 and a throttling device and other components are provided on the refrigerant pipeline so that the first heat exchanger 20 and the second heat exchanger 30 can complete the Carnot cycle.

[0062] The first heat exchange chamber 11 has a first return air port 11a and a first air outlet 11b, and the second heat exchange chamber 12 has a second return air port 12a and a second air outlet 12b. The first return air port 11a and the second return air port 12a can be connected to the outside respectively to provide air flow for heat exchange for the air conditioner host 100.

[0063] The first housing 10 of the air-conditioning main unit 100 integrates the first heat exchanger 20 and the second heat exchanger 30 into one, thereby improving the integration of the air-conditioning main unit 100. There is no need to set up an air-conditioning outdoor unit, and there is no need to set up an outdoor unit installation position outdoors, which reduces the number of components of the kitchen air-conditioning system 1000 and makes the installation of the kitchen air-conditioning system 1000 simpler and more convenient.

[0064] Specifically, an air-conditioning blower fan 71 is provided in the first heat exchange chamber 11 . When the air-conditioning blower fan 71 is in operation, it draws air from the first air return port 11 a and blows the air out from the first air outlet 11 b .

[0065] like Figures 9-11 As shown, the range hood main unit 200 includes a second housing 210 and an oil filter 220. An oil fume passage 211 is provided within the second housing 210, and the oil filter 220 is disposed within the oil fume passage 211. For example, the oil filter 220 can be disposed at the oil fume inlet 211a of the oil fume passage 211. The oil fume passage 211 has an oil fume inlet 211a and a flue outlet 211b, both of which are formed on the second housing 210. The oil filter 220 can filter the oil fume within the oil fume passage 211, thereby achieving the basic oil and smoke filtering function of the range hood main unit 200.

[0066] A heat exchange duct 212 is also provided in the second housing 210 of the range hood main unit 200. The heat exchange duct 212 has an air-conditioning outlet 212a and an air-conditioning inlet 212b. The air-conditioning outlet 212a and the air-conditioning inlet 212b are both provided on the second housing 210, and the air-conditioning inlet 212b is connected to the first air outlet 11b through the air outlet duct 903.

[0067] The low-temperature or high-temperature airflow generated by the air-conditioning host 100 can be transmitted to the heat exchange duct 212 in the range hood host 200 through the air outlet duct 903, and blown from the range hood host 200 to the kitchen through the air-conditioning outlet 212a of the heat exchange duct 212, or even directly blown to the user, effectively improving the kitchen temperature of the user during the cooking process and improving the user's cooking comfort.

[0068] By providing a heat exchange duct 212 on the second housing 210 of the range hood main unit 200, the airflow generated by the air conditioner main unit 100 can be blown toward the user through the range hood main unit 200. When the air outlet 212a is located on the second housing 210, the air flow is essentially within the user's cooking area, which better matches the user's work position and simplifies the layout of the kitchen air conditioning system 1000.

[0069] The exhaust fan 300 is connected to the second air outlet 12b and the smoke duct outlet 211b respectively to discharge the air in the second heat exchange chamber 12 and the oil smoke duct 211.

[0070] The exhaust fan 300 can act on the range hood main unit 200 and the air conditioner main unit 100 simultaneously, providing power for the flow of air in the oil fume duct 211 and the second heat exchange chamber 12, respectively. The exhaust fan 300 can selectively serve the range hood main unit 200 or the air conditioner main unit 100. The configuration of the exhaust fan 300 allows the gas after heat exchange in the second heat exchange chamber 12 and the smoke in the oil fume duct 211 after filtering to be driven by the exhaust fan 300 and discharged toward the outside. This integration allows the flow of air and smoke in the second heat exchange chamber 12 to be discharged by the exhaust fan 300. Moreover, after such a configuration, the exhaust of the two gases can be set up in the same pipeline system, which not only reduces the number of parts, but also shortens the pipeline length, making the pipeline connection simpler.

[0071] Reference Figure 5-Figure 7 The second return air vent 12a is connected to the fresh air duct 901. The second return air vent 12a can be connected to the space outside the kitchen through the fresh air duct 901, so that the second heat exchange chamber 12 can inhale air from the space outside the kitchen. The connection position of the other end of the fresh air duct 901 is not limited. Figure 1 In the example, one end of the fresh air duct 901 is connected to the second return air vent 12a, and the other end extends to the right to connect to the outside. In some solutions, the fresh air duct 901 can extend from the second return air vent 12a to other rooms, such as the living room. This arrangement not only draws air from other rooms into the air conditioner main unit 100 for heat exchange with the second heat exchanger 30, but also promotes air circulation in other rooms. In this case, if the windows in other rooms are opened, the pressure difference will allow fresh air from outside to be replenished into the room, achieving air circulation in the room.

[0072] The first housing 10 is provided with a fresh air vent 14 for connecting the first heat exchange chamber 11 and the second heat exchange chamber 12. The first housing 10 is also provided with a fresh air switch assembly 60 for opening and closing the fresh air vent 14. When the fresh air vent 14 is open, the first heat exchange chamber 11 can be replenished with fresh air through the second heat exchange chamber 12. When the first heat exchange chamber 11 needs fresh air, it is not necessary for the first return air vent 11a of the first heat exchange chamber 11 to also be connected to the outside. This is equivalent to the fresh air drawn in by the fresh air duct 901 being supplied to both the second heat exchange chamber 12 and the first heat exchange chamber 11.

[0073] In the solution of the present application, since the exhaust fan 300 can drive the flow of smoke in the oil fume duct 211 and also drive the flow of air in the second heat exchange chamber 12, the exhaust fan 300 has dual functions and can be used in a variety of ways as needed. For example, the exhaust fan 300 can only be connected to the oil fume duct 211 and the second heat exchange chamber 12 in a selective manner (for example, the three are connected using a switchable three-way valve). When the exhaust fan 300 is connected to the oil fume duct 211, the flow between the exhaust fan 300 and the second heat exchange chamber 12 is completely disconnected; when the exhaust fan 300 is connected to the second heat exchange chamber 12, the flow between the exhaust fan 300 and the oil fume duct 211 is completely disconnected. In this way, heat exchange and oil fume extraction can only be carried out separately. In some solutions, when the exhaust fan 300 is in operation, it simultaneously draws gas from the oil fume duct 211 and the second heat exchange chamber 12, so that heat exchange and oil fume extraction can be carried out simultaneously. In another embodiment, the kitchen air conditioning system 1000 further includes a ratio adjustment device for adjusting the ratio of gas sucked into the fume duct 211 and the second heat exchange chamber 12 when the exhaust fan 300 is running. In this way, the kitchen air conditioning system 1000 can perform heat exchange and fume extraction separately or simultaneously.

[0074] The provision of fresh air vent 14 enables kitchen air conditioning system 1000 to operate in at least a cooling mode, a fume extraction mode, and a fresh air mode. The following describes the operating modes when fresh air vent 14 is provided, using as an example a scenario where exhaust fan 300 can selectively connect to either fume duct 211 or second heat exchange chamber 12.

[0075] In cooling mode, the fresh air switch assembly 60 closes the fresh air vent 14, and the compressor 40, the air conditioner blower 71, and the exhaust fan 300 all operate. When the compressor 40 operates, the first heat exchanger 20 generates cooling, while the second heat exchanger 30 generates heating. When the air conditioner blower 71 operates, it draws air from the first return air inlet 11a into the first heat exchange chamber 11. This air, cooled by the flow through the first heat exchanger 20, is then blown from the first air outlet 11b through the outlet duct 903 into the heat exchange duct 212 of the range hood main unit 200. Finally, the cool air is blown out from the air conditioner outlet 212a. When the exhaust fan 300 is running, it drives air to be sucked in from the first return air port 11a. The sucked air flows through the first heat exchanger 20 and its temperature decreases. The low-temperature air is sucked into the second heat exchange chamber 12 from the fresh air duct 901 and the second return air port 12a. The sucked air flows through the second heat exchanger 30 and its temperature increases. The high-temperature air can be discharged from the exhaust duct 902.

[0076] In the oil fume extraction mode, the exhaust fan 300 operates to drive the oil fume to be sucked into the oil fume channel 211 from the oil fume inlet 211 a and then discharged through the exhaust fan 300 and the exhaust pipe 902 .

[0077] In fresh air mode, the fresh air switch assembly 60 opens the fresh air vent 14, and the air conditioner blower 71 operates. When the air conditioner blower 71 operates, fresh air is drawn into the first heat exchange chamber 11 via the fresh air duct 901, the second return air vent 12a, the second heat exchange chamber 12, and the fresh air vent 14. The drawn air is then blown from the first air outlet 11b through the air outlet duct 903 into the heat exchange air duct 212 of the range hood main unit 200, and finally out through the air conditioner outlet 212a.

[0078] In this solution, fresh air mode and range hood extraction mode can be operated simultaneously. In this mode, the compressor 40 is not running, the air conditioner blower 71 and exhaust fan 300 are both running, and the fresh air switch assembly 60 opens the fresh air vent 14. When the air conditioner blower 71 is running, fresh air is drawn into the first heat exchange chamber 11 via the fresh air duct 901, the second return air vent 12a, the second heat exchange chamber 12, and the fresh air vent 14. The drawn air is then blown from the first air outlet 11b through the outlet duct 903 into the heat exchange air duct 212 of the range hood main unit 200, and finally out through the air conditioner outlet 212a. The exhaust fan 300 is running, driving the oil smoke from the oil smoke inlet 211a into the oil smoke duct 211, where it is then discharged through the exhaust fan 300 and the exhaust duct 902.

[0079] Of course, when the above components have other forms, the kitchen air conditioning system 1000 can also have more modes, or a combination of more modes. In some solutions, the kitchen air conditioning system 1000 also has a heating mode, a dehumidification mode, etc., which will not be described in detail here.

[0080] According to the kitchen air conditioning system 1000 of the present invention, an air conditioning host 100 and a range hood host 200 are provided in the kitchen air conditioning system 1000. A heat exchange air duct 212 is provided on the range hood host 200. The heat exchange air duct 212 is connected to the air conditioning outlet 212a of the air conditioning host 100. The range hood host 200 can guide the airflow after heat exchange to the kitchen. The range hood host 200 integrates the dual functions of extracting oil smoke and discharging the airflow after heat exchange, which effectively improves the ambient temperature of the user during the cooking process. The kitchen air conditioning system 1000 has a high degree of integration, a small number of components, and a simple and convenient layout.

[0081] Furthermore, the provision of the fresh air vent 14 and the fresh air switch assembly 60 allows the first heat exchange chamber 11 and the second heat exchange chamber 12 to share the fresh air from the fresh air duct 901. This allows the first heat exchange chamber 11 to operate in fresh air mode without requiring a separate heightened fresh air duct. This allows the kitchen air conditioning system 1000 to operate in both fresh air mode and fume extraction mode simultaneously. When these two modes are in operation simultaneously, fresh air is continuously replenished, and indoor fume is continuously drawn into the fume inlet 211a. A slight positive pressure is formed at the air conditioning outlet 212a, while a slight negative pressure is formed at the fume inlet 211a. The replenished fresh air has a fume-repelling effect, making it easier for kitchen fume and surrounding air to be drawn away by the fume inlet 211a. This improves fume absorption, and the replenished fresh air can moderate the temperature in the kitchen, making it healthier for users to breathe fresh air in the kitchen.

[0082] In some embodiments, as Figure 8 As shown, the fresh air switch assembly 60 includes a rotating door 61 connected to the first housing 10. The rotating door 61 is rotatable between a closed position and an open position. Controlling the opening and closing of the fresh air vent 14 by rotating the door 61 not only simplifies the structure but also fully utilizes the space within the first housing 10 for operation. Furthermore, the opening and closing of the fresh air vent 14 is controlled by the direction of rotation, making operation very quick and convenient.

[0083] Specifically, if Figure 5 As shown, in the closed position, the rotating door 61 covers the fresh air vent 14. Figure 6 As shown, in the open position, the rotating door 61 opens the fresh air vent 14, and the rotating door 61 is located in the second heat exchange chamber 12. It can be understood here that since an air-conditioning blower 71 is also required to be provided in the first heat exchange chamber 11, it is arranged in the second heat exchange chamber 12, which can provide a larger space for activities and a more convenient arrangement.

[0084] More specifically, in the open position, the rotary door 61 is at least partially blocked between the second return air port 12a and the second air outlet 12b. In this way, the rotary door 61 can block the airflow toward the second air outlet 12b, allowing fresh air to flow into the first heat exchange chamber 11.

[0085] In some schemes, such as Figure 6 and Figure 8 As shown, within the second heat exchange chamber 12, the second return air inlet 12a and the second air outlet 12b are located on opposite sides of the second heat exchanger 30, and the fresh air vent 14 is located between the second heat exchanger 30 and the second return air inlet 12a. When the swing door 61 is in the open position, the swing door 61 is positioned away from the fresh air vent 14 in the direction toward the second return air inlet 12a to direct airflow toward the fresh air vent 14. In this way, the swing door 61 forms a kind of air guide, more easily directing airflow toward the fresh air vent 14, thereby reducing wind resistance.

[0086] In some specific embodiments, Figure 8 As shown, the fresh air switch assembly 60 also includes a swing door motor 62, a swing door gear (not shown), and a swing door rack 64. The swing door gear is connected to the swing door motor 62. The swing door rack 64 is arc-shaped. One end of the swing door rack 64 is connected to the swing door 61, and the swing door rack 64 meshes with the swing door gear. In other words, the swing door 61 is powered by the swing door motor 62. Driven by the swing door motor 62, the swing door 61 can open and close smoothly. The swing door motor 62 also has a fast opening and closing response speed, allowing it to operate quickly upon receiving a command.

[0087] Here, a revolving door gear and a revolving door rack 64 are meshed to drive the opening and closing of the revolving door 61. This allows the force point of the revolving door 61 to be away from the rotating shaft of the revolving door 61, making the opening and closing of the revolving door 61 more labor-saving. The cooperation between the revolving door gear and the revolving door rack 64 can achieve the effect of reducing speed and increasing torque, and can also provide a buffer and protection for the revolving door motor 62.

[0088] Optionally, the fresh air switch assembly 60 further includes a fresh air filter 66, which is disposed at the fresh air vent 14. This allows fresh air entering the first heat exchange chamber 11 to be filtered, thereby improving the cleanliness of the air entering the room. Furthermore, the fresh air filter 66 may be a filter foam or other component with low air resistance and filtering capabilities.

[0089] Furthermore, the fresh air switch assembly 60 includes a swing door card case 65, which is mounted on the bottom wall of the second heat exchange chamber 12. The swing door motor 62 is mounted on the swing door card case 65. The swing door card case 65 is mounted on the swing door rack 64, thereby limiting the position of the swing door rack 64. Furthermore, when the swing door 61 is opened and abuts against the swing door card case 65, the swing door card case 65 acts as a stop. When airflow pushes against the swing door 61, the swing door card case 65 absorbs the wind pressure, thereby enhancing the protection of the fresh air switch assembly 60.

[0090] Of course, the solution of the present application is not limited to this. For example, the revolving door motor 62 is directly connected to the rotating shaft of the revolving door 61. For another example, the fresh air switch assembly 60 may include a static door and a moving door (not shown in the figure). The static door is fixedly arranged at the fresh air vent 14, and a static door through hole is provided on the static door, and a moving door through hole is provided on the moving door. The revolving door motor 62 is connected to the moving door, and drives the moving door to rotate relative to the static door. In the closed position, the moving door through hole on the moving door and the static door through hole on the static door are staggered, so that the fresh air vent 14 can be closed. In the open position, the moving door through hole on the moving door and the static door through hole on the static door are opposite to each other, so that the fresh air vent 14 can be connected.

[0091] In some embodiments, as Figure 4-Figure 7As shown, the first shell 10 is a rectangular box as a whole, and an air-conditioning partition 15 is provided in the first shell 10 to divide the first shell 10 into a first heat exchange chamber 11 and a second heat exchange chamber 12. The first heat exchange chamber 11 and the second heat exchange chamber 12 are respectively formed as rectangular cavities.

[0092] The first return air inlet 11a and the first air outlet 11b are located on opposite sides of the first heat exchange chamber 11, and the second return air inlet 12a and the second air outlet 12b are located on opposite sides of the second heat exchange chamber 12. The first return air inlet 11a and the second return air inlet 12a are located on the same side of the first housing 10, and the first air outlet 11b and the second air outlet 12b are located on the same side of the first housing 10.

[0093] Within the first heat exchange chamber 11, the first heat exchanger 20 is positioned adjacent to the first return air port 11a, and the air conditioning blower 71 is positioned adjacent to the first air outlet 11b. Within the second heat exchange chamber 12, the compressor 40 is positioned adjacent to the second return air port 12a, and the second heat exchanger 30 is positioned adjacent to the second air outlet 12b. This arrangement positions the first and second heat exchangers 20 and 30 on opposite sides of the first housing 10, placing them at a distance from each other and facilitating thermal insulation between them.

[0094] Optionally, a condensation water outlet 13 is further provided on the first housing 10 for discharging the condensation water. Figure 5 As shown, a condensate outlet 13 is provided in the first heat exchange chamber 11 to discharge condensate when the air conditioner 100 is in cooling mode. In some embodiments, a condensate outlet 13 is also provided in the second heat exchange chamber 12 to discharge condensate when the air conditioner 100 is in heating mode.

[0095] Further optionally, a plurality of legs 50 are provided on the bottom wall of the first housing 10, and the legs 50 are used to connect to the ceiling 800 to fix the first housing 10 on the ceiling 800. Figure 5 In the example, four corners of the first housing 10 are provided with supporting feet 50 to improve the connection stability.

[0096] like Figure 1 As shown, the air conditioner host 100 is installed above the ceiling 800, so that the air conditioner host 100 can be hidden by the ceiling 800. Specifically, the pipes connected to the air conditioner host 100 are also installed above the ceiling 800, which not only improves the aesthetics, but also allows the ceiling 800 to be used for installation and fixation.

[0097] In some embodiments, the oil fume inlet 211a is set at the bottom of the range hood main unit 200, which is close to the stove, which is conducive to sucking more oil fume into the oil fume channel 211 in a timely manner.

[0098] The shape of the range hood main unit 200 can refer to the shape and structure of existing range hoods, and can adopt the shape of a near-suction range hood or a top-suction range hood. In some embodiments, the range hood main unit 200 is also provided with a fume hood at the bottom, and the fume inlet 211a is located at the bottom of the fume hood, thereby appropriately increasing the negative pressure area and expanding the suction range. Of course, in some embodiments, the fume inlets 211a can also be provided on the front, left, or right sides of the range hood main unit 200 to further expand the suction range.

[0099] Specifically, the oil filter 220 is an oil filter grid, which may be single-layer or multi-layer, and is not limited here.

[0100] In some embodiments, as Figure 11 As shown, the heat exchange duct 212 and the oil fume duct 211 are arranged in parallel. The heat exchange duct 212 can be used to circulate the low-temperature airflow generated by the air-conditioning host 100, thereby reducing the temperature of the heat exchange duct 212 wall. The oil fume duct 211 adjacent to the heat exchange duct 212 can perform heat exchange on the wall of the heat exchange duct 212 to reduce the temperature of the wall of the oil fume duct 211, thereby making the oil circulating in the oil fume duct 211 easier to condense, thereby improving the filtering effect of the range hood host 200 on oil fume.

[0101] In some embodiments, as Figure 11 As shown, the heat exchange duct 212 and the oil fume duct 211 can share the same pipe wall, and adjacent heat exchange duct 212 and oil fume duct 211 can be provided on the second housing 210, and the pipe wall of the heat exchange duct 212 and the pipe wall of the oil fume duct 211 are the same shell structure, thereby improving the heat exchange effect of the heat exchange duct 212 on the oil fume duct 211, and enhancing the condensation effect of the oil fume duct 211 on the oil fume.

[0102] Optionally, the heat exchange duct 212 and the oil fume duct 211 are arranged in the front-to-back direction, with the heat exchange duct 212 located in front of the oil fume duct 211. This allows the heat exchange duct 212 to be closer to the user in front of the stove. This arrangement can isolate the heat radiated forward from the oil fume duct 211, improving user comfort.

[0103] In some embodiments, as Figure 1 As shown, the range hood main unit 200 is mainly arranged below the kitchen ceiling 800, and the top of the range hood main unit 200 extends to the ceiling 800. Figure 9 As shown, the flue outlet 211b and the air-conditioning air inlet 212b are located on the top of the range hood main unit 200, which makes it easy to connect with other structures, and the connection point can be hidden by the ceiling 800.

[0104] In some embodiments, multiple air outlets 212a are provided, spaced apart on the second housing 210. This increases the range of airflow and expands the area for improving temperature. Alternatively, the user can select to open different air outlets 212a to meet their individual needs.

[0105] For example, if the user feels the ambient temperature is too high, they can open multiple air outlets 212a to increase the air volume and quickly lower the ambient temperature. The user can select air outlets 212a at different heights according to their height. The user can also select the corresponding air outlet 212a according to the location of the cooking stove to reduce the feeling of being scorched.

[0106] In some embodiments, a plurality of air conditioning vents 212a are respectively distributed on the front panel, left panel, and right panel of the second housing 210. The air conditioning vents 212a provided on the front panel of the second housing 210 can be directly opposite the user's work area to improve the temperature in the area directly opposite the user, while the air conditioning vents 212a located on the left and right panels of the second interface 312 can be selectively opened and closed. The air conditioning vents 212a located on the left and right panels can be used to increase the range and air volume of air outlet, thereby increasing the air outlet area and applicability of the kitchen air conditioning system 1000.

[0107] Optionally, at least one air conditioning outlet 212a is located on the front. Furthermore, the air conditioning outlet 212a is located above the oil fume inlet 211a. Since the oil fume inlet 211a can draw in oil fumes below the oil fume inlet 211a, if the air conditioning outlet 212a is located below the oil fume inlet 211a, the air flow from the air conditioning outlet will be drawn away by the oil fume inlet 211a, preventing the air from cooling. By locating the air conditioning outlet 212a above the oil fume inlet 211a, the air conditioning outlet 212a is not interfered with by the oil fume inlet 211a, ensuring that the air from the air conditioning outlet 212a can be delivered to the user's surroundings, thereby improving the user's working environment.

[0108] In a specific embodiment of the present invention, the air-conditioning outlet 212a located on the front panel of the second housing 210 can be constructed as a long strip of air outlet. The air-conditioning outlet 212a can extend along the width direction of the second housing 210, and the air-conditioning outlet 212a can even be almost the same width as the second housing 210, thereby increasing the air outlet width and improving the area covered by the air-conditioning outlet 212a.

[0109] The air-conditioning outlet 212a located on the front panel of the second housing 210 is constructed as a rectangular hole, which extends in the horizontal direction of the front panel of the second housing 210. The air flow after passing through the first heat exchange chamber 11 is guided through the air-conditioning outlet 212a to the front area facing the range hood main unit 200, and heat is exchanged in this area to improve the ambient temperature of the front area.

[0110] The air-conditioning outlets 212a located on the left and right panels of the second housing 210 can also be constructed as rectangular outlets. The two air-conditioning outlets 212a located on the left and right panels of the second housing 210 can further expand the air outlet range covered by the air-conditioning outlets 212a located on the range hood main unit 200, and the air-conditioning outlets 212a located on the left and right panels can be optionally closed.

[0111] Multiple stoves can be set directly below the range hood main unit 200, and the air-conditioning outlets 212a located on the left and right panels can be opened or closed according to the positions of the open stoves. For example, when the stove on the left is opened, the air-conditioning outlets 212a on the left panel are opened to improve the ambient temperature of the corresponding area.

[0112] In some specific embodiments, Figure 9 and Figure 10 As shown, each air-conditioning outlet 212a is provided with an air guide plate for adjusting the air outlet direction, wherein the air guide plate may include a first air guide plate 250 , a second air guide plate 260 and a third air guide plate 261 .

[0113] Among them, such as Figure 12 As shown, the first air guide plate 250 includes a pivot portion 251 and an air guide arc panel 252 , wherein the pivot portion 251 is formed on the inner side of the air guide arc panel 252 .

[0114] The pivoting portion 251 is connected to the first wind guide driving member 262. Figure 9A first air guide drive 262 is shown. The output end of the first air guide drive 262 drives the pivot portion 251 to rotate. It should be noted that during the rotation of the pivot portion 251 by the first air guide drive 262, the rotation axis of the output shaft of the first air guide drive 262 is aligned with the direction of extension of the air outlet 212a located on the front panel of the second housing 210. An air guide arc panel 252 is provided on the side of the pivot portion 251 facing away from the air outlet 212a. The air guide arc panel 252 is configured as an arc that protrudes away from the air outlet 212a, giving the range hood main unit 200 a more rounded and aesthetically pleasing appearance. When the first air guide drive 262 drives the first air guide plate 250 to rotate, at least a portion of the first air guide plate 250 can rotate to be accommodated within the air outlet 212a located on the front of the second housing 210, thereby opening the air outlet 212a located on the front of the second housing 210 and concealing the first air guide plate 250.

[0115] Furthermore, since the outer side of the air guide arc panel 252 of the first air guide plate 250 is constructed to be an arc that protrudes from the front panel of the second housing 210, the first air guide drive 262 adjusts the air outlet area of ​​the air-conditioning outlet 212a located on the front of the second housing 210 by changing the pivot angle of the first air guide plate 250, and the user can adjust the rotation angle of the first air guide plate 250.

[0116] Air conditioning outlets 212a are provided on the left and right panels of the first casing 10, and second air guide driving members 263 and third air guide driving members 264 for driving the second air guide plate 260 and the third air guide plate 261 respectively can be provided in the air conditioning outlet 212a. The second air guide plate 260 and the third air guide plate 261 can both be constructed as rectangular plates.

[0117] Alternatively, as Figure 13 As shown, the second air guide drive member 263 and the third air guide drive member 264 can both be drive motors, and are respectively arranged on the lower side of the corresponding air-conditioning outlet 212a. The output shaft of the drive motor can be connected to the corresponding second air guide plate 260 and the third air guide plate 261. The output shaft of the drive motor is the same as the extension direction of the corresponding second air guide plate 260 and the third air guide plate 261, so as to drive the second air guide plate 260 and the third air guide plate 261 to open in a direction away from each other, thereby increasing the air outlet width of the range hood main unit 200.

[0118] Similarly, the rotation angles of the second air guide plate 260 and the third air guide plate 261 can be selectively adjusted. By controlling the driving motors of the second air guide plate 260 and the third air guide plate 261, the width of the air outlet range of the range hood main unit 200 can be adaptively adjusted, and can be adjusted according to the user's choice.

[0119] like Figure 11 As shown, in some embodiments, the kitchen air conditioning system 1000 further includes a switch panel assembly 271 for adjusting the size of the oil fume inlet 211a. The switch panel assembly 271 is movably disposed on the second housing 210. The switch panel assembly 271 can be disposed on the front of the second housing 210. The front of the second housing 210 is provided with an oil fume inlet 211a. The oil fume inlet 211a is disposed on the lower side of the front panel of the second housing 210. The oil fume inlet 211a can include a plurality of elongated holes penetrating the front panel of the second housing 210, wherein each elongated hole extends in the height direction and is spaced apart in the width direction of the front panel of the second housing 210.

[0120] Optionally, the switch panel assembly 271 is rotatably or liftably mounted on the second housing 210. The switch panel assembly 271 has an open state and a closed state. When in the closed state, the switch panel assembly 271 covers the front of the second housing 210, thereby covering the oil fume inlet 211a on the front of the second housing 210, leaving only the oil fume inlet 211a located at the lower end of the second housing 210 open. The closed state of the switch panel assembly 271 is suitable for conditions where the amount of oil fume is low. Keeping the switch panel in the closed state reduces the space occupied by the range hood main unit 200.

[0121] When the switch panel assembly 271 switches from a closed state to an open state, the upper end of the switch panel assembly 271 is pivotally connected to the front panel of the second housing 210, and the switch panel assembly 271 can also be driven by a drive motor, and the output shaft of the drive motor is directed in the width direction of the front panel of the second interface 312. During the rotation of the second housing 210, the inner side surface of the switch panel assembly 271 can be pivoted in the direction away from the front panel of the second housing 210, so that the switch panel assembly 271 and the front panel of the second housing 210 are perpendicular, so that a certain angle is formed between the switch panel assembly 271 and the front panel of the second housing 210, so as to open the oil fume inlet 211a located on the front panel of the second housing 210 and increase the area of ​​the oil fume inlet 211a. Since the switch panel assembly 271 rotates in the direction away from the front panel of the second housing 210, the space occupied by the range hood main unit 200 increases, but at the same time the oil fume inlet 211a located on the front panel of the second housing 210 is opened, thereby improving the smoke extraction capacity of the range hood main unit 200 and making the range hood main unit 200 suitable for extracting large oil fumes.

[0122] In one embodiment of the present invention, the switch panel assembly 271 can be turned on and off according to user settings or automatically turned on by a smoke sensor when the amount of smoke exceeds a preset value. The switch panel assembly 271 can also be turned on in a combination of the above two ways, with the user's manual setting taking precedence over the automatic detection. This can further improve the automation level of the kitchen air conditioning system 1000.

[0123] In some embodiments, as Figure 10 、 Figure 11 As shown, an oil collecting box 272 is further provided on the lower side of the second housing 210, and the lower end of the second housing 210 can be constructed as a trapezoidal structure, and the thickness of the trapezoidal structure gradually decreases in the direction extending toward the lower side, wherein the front side of the trapezoidal structure is provided with the above-mentioned oil fume inlet 211a that is not blocked by the switch panel assembly 271, and this part of the oil fume inlet 211a is provided on the front side surface of the trapezoidal structure, and the front side surface of the trapezoidal structure is an inclined surface, and providing this part of the oil fume inlet 211a on the inclined surface can increase the cross-sectional area of ​​this part of the oil fume inlet 211a, so that it has sufficient ability to absorb oil fume when the switch panel assembly 271 is not opened.

[0124] Furthermore, the lower end of second housing 210 is constructed in a trapezoidal shape, which facilitates the flow of oil fumes through oil fume inlet 211a. Under the influence of gravity, the fumes flow toward oil collection box 272, located at the bottom of the trapezoidal structure. The upper end of oil collection box 272 is formed with an oil collection box opening. The width of the oil collection box opening is greater than the width of the trapezoidal structure floor, and at least a portion of the oil collection box opening is aligned with the oil fume inlet 211a in the height direction. This ensures that the oil fumes filtered by oil fume inlet 211a, located on the front side of the trapezoidal structure, fall into oil collection box 272, preventing oil fumes from dripping onto the countertop.

[0125] like Figure 13 As shown, in some embodiments, the heat exchange air duct 212 has a cold air outlet 212c that supplies air toward the oil filter 220. A cold air switch 280 for opening or closing the cold air outlet 212c is provided. By providing the cold air outlet 212c and the cold air switch 280, the cold air supplied from the heat exchange air duct 212 can be directed toward the oil filter 220 under the guidance of the cold air switch 280, thereby condensing the oil stains on the oil filter 220 and quickly condensing the hot oil smoke. When the range hood main unit 200 is performing a range hood extraction operation, by opening the cold air switch 280 to direct the low-temperature airflow toward the oil filter 220, the temperature of the oil filter 220 is reduced, thereby improving the oil filtering effect of the oil filter 220.

[0126] In a specific embodiment of the present invention, a rotatable switch panel assembly 271 is provided on the second housing 210. The switch panel assembly 271 is rotated to select whether to cover or open the oil fume inlet 211a located on the front panel of the second housing 210, and an oil filter 220 is provided at the oil fume inlet 211a. The oil filter can be constructed as a grille formed on the front panel of the second housing 210, and the oil filter grille is formed with a plurality of long strip holes, which are constructed as the oil fume inlet 211a.

[0127] The switch panel assembly 271 can be rotatably arranged on the front panel of the second housing 210. When the switch panel assembly 271 is turned in the direction away from the front panel of the second housing 210, the long hole can be exposed to improve the smoke absorption effect of the range hood host 200. The cold air outlet can be arranged on the inner side or lower end of the switch panel assembly 271, and the cavity in the switch panel assembly 271 can be constructed as part of the heat exchange air duct 212. The cold air outlet 212c is arranged on the switch panel assembly 2 71, and is arranged toward the inner side of the front panel of the second casing 210. The cold air switch 280 is openably arranged at the cold air outlet, and the cold air switch 280 is opened after the switch panel assembly 271 is opened. After the cold air switch 280 is turned on, it can extend toward the front panel of the second casing 210, and can be extended toward the oil filter 220. The cold air blown out from the cold air outlet can be blown toward the oil filter 220 under the guidance of the cold air switch 280 to improve the oil filtering effect of the oil filter 220.

[0128] In some embodiments, the cold air switch 280 is configured to direct the heated air to the oil filter 220 when the cold air outlet is open. It should be noted that when the air conditioner 100 is cooling, the gas discharged after passing through the first heat exchange chamber 11 is low-temperature gas. After entering the heat exchange air duct 212, the low-temperature gas is blown toward the oil filter 220 under the guidance of the cold air switch 280. This utilizes the low-temperature gas generated by the air conditioner 100 to accelerate the condensation of oil smoke and improve the oil filtering capacity of the range hood 200.

[0129] In some embodiments, the air conditioner host 100 may also have a heating working condition. The gas discharged after passing through the first heat exchange chamber 11 is high-temperature gas. After the high-temperature gas enters the heat exchange air duct 212, it is blown toward the oil filter 220 under the guidance of the cold air switch 280 to melt the oil stains on the oil filter 220 and facilitate the cleaning of the oil filter 220.

[0130] In one embodiment of the present invention, a cold air switch driving motor 281 for driving the cold air switch 280 to rotate is provided on the switch panel assembly 271, and the output shaft of the cold air switch driving motor 281 is used to drive the cold air switch 280 to rotate to control the opening and closing of the cold air outlet 212c.

[0131] In some embodiments, as Figure 1-Figure 3 As shown, the exhaust fan 300 is arranged on the outside of the first casing 10 and on the outside of the second casing 210. By arranging the exhaust fan 300 on the outside of the first casing 10 and the second casing 210 respectively, the layout of the kitchen air-conditioning system 1000 can be made more flexible, and the layout positions of the air-conditioning host 100 and the range hood host 200 will not be restricted. By arranging the exhaust fan 300 separately, it can be arranged in a manner with the shortest pipeline according to the specific structure of the user's kitchen, thereby improving the flexibility of the layout of the kitchen air-conditioning system 1000.

[0132] like Figure 14-17 As shown, the exhaust fan 300 has a first interface 311 connected to the second air outlet 12b, and the exhaust fan 300 may include a fan casing 310. The fan casing 310 is internally provided with a accommodating space for accommodating a wind wheel. The wind wheel rotates in the fan casing 310 to generate negative pressure at the first interface 311. The first interface 311 is connected to the second air outlet 12b. The second heat exchange chamber 12 in the air-conditioning host 100 can exchange heat with the air flow passing through the second heat exchanger 30, wherein the second heat exchanger 30 in the second heat exchange chamber 12 can be a condenser. The condenser releases heat through the condensation of the internal refrigerant, thereby increasing the temperature of the air flow flowing through the second heat exchange chamber 12, and the air flow with increased temperature can be discharged from the air-conditioning host 100 through the second air outlet 12b. The first interface 311 of the exhaust fan 300 is connected to the second air outlet 12b. Under the action of the rotation of the wind wheel, negative pressure is generated at the first interface 311 to discharge the air flow passing through the second heat exchange chamber 12, while improving the air intake efficiency of the second return air outlet 12a.

[0133] In another embodiment of the present invention, a wind wheel can be separately disposed within the second heat exchange chamber 12. The wind wheel can direct the airflow within the second heat exchange chamber 12, which is equivalent to disposing a fan within the second heat exchange chamber 12 to independently control the air intake and exhaust of the air conditioner 100. Furthermore, the wind wheel can increase the return air volume of the second return air port 12a and the outlet air volume of the second air outlet 12b, thereby helping to improve the heat exchange efficiency of the air conditioner 100.

[0134] In some embodiments, the exhaust fan 300 has a second interface 312 connected to the flue outlet 211b, and the wind wheel rotates in the fan housing 310 to generate negative pressure at the second interface 312. The second interface 312 is connected to the flue outlet 211b. When the range hood host 200 performs oil fume removal work, the wind wheel rotates to drive the airflow and generate negative pressure at the second interface 312. The second interface 312 is connected to the oil fume outlet, so that the oil fume channel 211 in the range hood host 200 also generates negative pressure, and enables the range hood host 200 to perform oil fume extraction work.

[0135] In another embodiment of the present invention, a wind wheel can be separately installed on the range hood main unit 200. The wind wheel can guide the oil smoke in the oil smoke duct 211. This is equivalent to installing a fan on the range hood main unit 200, which can be used to independently control the exhaust operation of the range hood main unit 200. The wind wheel installed on the range hood main unit 200 can also increase the suction force of the oil smoke inlet 211a of the range hood main unit 200, allowing the range hood main unit 200 to operate independently of the air conditioner main unit 100.

[0136] In some embodiments, a third interface 313 is provided on the fan housing 310, and the third interface 313 is connected to the exhaust pipe 902. The third interface 313 can guide the airflow and / or oil smoke after heat exchange out of the fan housing 310 to be discharged to the exhaust pipe 902. It should be noted here that the third interface 313 is equivalent to the exhaust port of the fan housing, and the third interface 313 is connected to the exhaust pipe 902. The exhaust pipe 902 can be the flue in the kitchen room, or a hose connecting the third interface 313 to the flue in the kitchen room. The third interface 313 can guide the air after heat exchange generated by the air-conditioning host 100 and the oil smoke sucked by the range hood host 200.

[0137] Among them, the range hood main unit 200 and the air conditioner main unit 100 can work independently or in coordination, and the gas exported by the third interface 313 can be the gas with a higher temperature after passing through the second heat exchange chamber 12, or it can be the oil smoke sucked through the range hood main unit 200, or it can be a mixture of the above two gases.

[0138] In some embodiments, as Figure 16 As shown, the second interface 312 is provided with a second valve 322 for opening or closing the second interface 312. The second interface 312 is used to connect the oil fume channel 211 with the accommodating chamber in the fan casing 310 of the exhaust fan 300. The second valve 322 is set at the second interface 312, which can be used to select to open or close the second interface 312. When the second interface 312 is closed, the oil fume extraction function of the range hood host 200 is in a closed state, and the oil fume in the oil fume channel 211 will not enter the accommodating chamber of the fan casing 310. The purpose of the first valve 321 is to prevent the oil fume in the oil fume channel 211 from entering the fan casing 310 of the exhaust fan 300, so as to avoid the oil fume from passing through the first interface 311 into the air-conditioning host 100, thereby avoiding the occurrence of oil fume cross-talk.

[0139] In addition, after the air conditioner host 100 is turned on alone, in order to prevent part of the airflow from entering the oil fume duct 211 through the second interface 312, the first valve 321 can also ensure that the high-temperature airflow after heat exchange will not enter the room through the oil fume duct 211.

[0140] In some embodiments, as Figure 17 As shown, the first interface 311 is provided with a first valve 321 for opening or closing the first interface 311. The first interface 311 is a communication interface connecting the second heat exchange chamber 12 of the air conditioner main unit 100 and the accommodating chamber of the fan housing 310 of the exhaust fan 300. The first valve 321 is provided on the first interface 311 to control the opening and closing of the first interface 311. This prevents the airflow in the accommodating chamber of the fan housing 310 of the exhaust fan 300 from flowing back into the air conditioner main unit 100.

[0141] For example, when the range hood main unit 200 is used alone and the air conditioning main unit 100 is not turned on, the range hood main unit 200 draws in oil smoke through the oil smoke channel 211, and the oil smoke enters the accommodating cavity of the fan housing of the exhaust fan 300 through the second interface 312. Since the accommodating cavity of the fan housing mainly contains oil smoke, the air conditioning main unit 100 is not turned on at this time, and the oil smoke can enter the second heat exchange chamber 12 through the first interface 311 on the fan housing, which will cause the oil smoke to flow, and the oil smoke can enter the kitchen through the second return air port 12a.

[0142] In addition, when the range hood main unit 200 and the air conditioner main unit 100 are not working, the gas from the exhaust pipe 902 may flow in a certain direction under the action of atmospheric pressure, and a first valve 321 is set at the first interface 311. The first interface 311 can be selectively opened or closed through the first valve 321 to prevent reverse airflow from entering the air conditioner main unit 100.

[0143] By setting a first valve 321 at the first interface 311, the first valve 321 is selectively opened or closed to control the first interface 311. When one of the air-conditioning host 100 or the range hood host 200 is working, the first valve 321 closes the first interface 311 to avoid the influence of the exhaust pipe and the range hood host 200 on the air-conditioning host 100.

[0144] In some embodiments, the exhaust fan 300 is disposed within the second heat exchange chamber 12. This placement of the exhaust fan 300 within the second heat exchange chamber 12 improves the integration of the kitchen air conditioning system 1000, eliminating the need for a separate exhaust fan 300. Instead, a range hood interface is provided on the first housing 10, allowing smoke drawn by the range hood unit 200 to enter the second heat exchange chamber 12 through the interface. The interface is connected to the flue outlet 211b via a range hood duct, allowing the fume duct 211 in the range hood unit 200 to directly communicate with the second heat exchange chamber 12. This embodiment also allows the range hood unit 200 and the air conditioning unit 100 to share the same exhaust fan 300, while also reducing the number of components in the kitchen air conditioning system 1000. This makes the layout of the kitchen air conditioning system 1000 more flexible and convenient.

[0145] In some embodiments, the kitchen air-conditioning system 1000 is further provided with a third valve for opening or closing the range hood interface. The third valve is set on the range hood interface and can be used to control the opening or closing of the oil fume channel 211 and the second heat exchange channel. When the air-conditioning host 100 and the range hood host 200 work synchronously, the third valve is opened to allow the smoke sucked by the range hood host 200 to enter the second heat exchange chamber 12 and be discharged synchronously with the air flow after heat exchange through the second heat exchanger 30 under the action of the exhaust fan 300. When the air-conditioning host 100 is turned on alone, the third valve can cut off the range hood interface so that the air flow generated by the exhaust fan 300 can act alone in the second heat exchange chamber 12, thereby reducing flow loss.

[0146] The third valve can also be used to block the oil smoke in the oil smoke channel 211 from entering the second heat exchange chamber 12, thereby preventing the oil smoke remaining in the oil smoke channel 211 from flowing when the air conditioner host 100 is not working, and preventing the oil smoke from entering the second heat exchange chamber 12.

[0147] like Figure 1-Figure 3 As shown, in some embodiments, the kitchen air conditioning system 1000 further includes a return air assembly 400, which is mounted on the kitchen ceiling 800. The air in the kitchen flows through the return air assembly 400 to the first return air vent 11a. The return air assembly 400 can direct the airflow from the kitchen into the ceiling 800. The return air assembly 400 connects the lower portion of the ceiling 800 with the upper portion of the ceiling 800. The airflow from the lower portion of the ceiling 800 enters the upper portion of the ceiling 800 through the return air assembly 400. The first return air vent 11a is open above the ceiling 800. The airflow from the upper portion of the ceiling 800 can enter the first return air vent 11a and then exchange heat with the corresponding heat exchanger to achieve the cooling or heating function of the air conditioning unit 100. By placing the return air assembly 400 on the ceiling 800, the return air layout of the air conditioning unit 100 is simplified.

[0148] In some embodiments, as Figure 18 and Figure 19 As shown, the return air assembly 400 includes a face frame 410 and a panel grille 420. The face frame 410 is suitable for being fixed to the kitchen ceiling 800, and the panel grille 420 is detachably mounted on the face frame 410. The ceiling 800 may be provided with a return air assembly mounting hole, and the face frame 410 may be fixed to the return air assembly mounting hole. The face frame 410 serves as the mounting base for the panel grille 420, and the panel grille 420 is detachably mounted on the face frame 410 to facilitate subsequent cleaning and maintenance of the panel grille 420.

[0149] like Figure 18 and Figure 19As shown, the face frame 410 includes an outer frame portion 411, which is annular in shape. A connecting frame 412 is disposed between opposing sides of the outer frame portion 411. Connecting frames 412 are provided with engaging holes 413 extending through the thickness of the outer frame 411. The panel grille 420 includes a grille body, on which hook portions 421 are rotatably disposed. At least a portion of the hook portions 421 can pass through and engage with the engaging holes 413 to connect the panel grille 420 to the face frame 410. To remove the panel grille 420 from the face frame 410, the hook portions 421 can be rotated to separate the panel grille 420 from the face frame 410, making disassembly between the panel grille 420 and the face frame 410 easy.

[0150] In a specific embodiment of the present invention, two spaced-apart and parallel connecting skeletons 412 are provided on the face frame 410, each connecting skeleton 412 is correspondingly provided with a snap-in hole 413, and two hook portions 421 are provided on the panel grille 420, each hook portion 421 is arranged opposite to the corresponding snap-in hole 413, and the two hook portions 421 rotate in opposite directions to facilitate the user to remove the panel grille 420 from the face frame 410 from the bottom side.
