[0039] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0040] In the description of this invention, it should be understood that the terms "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0041] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] The following is for reference. Figures 1-12 A kitchen air conditioning system 100 according to an embodiment of the present invention is described.

[0043] like Figure 1 As shown, a kitchen air conditioning system 100 according to a first aspect embodiment of the present invention includes: an air conditioning component 10, a main unit component 30, an air outlet component 20, and a range hood component.

[0044] The air conditioning component 10 is used for air conditioning operations such as cooling and heating in the kitchen space A, and the range hood component is used for fume extraction in the kitchen space A.

[0045] like Figures 2-4As shown, the air conditioning component 10 includes a first housing 11, which has a first air inlet 111 and a first air outlet 112. The first housing 11 contains a first fan 12 and a first heat exchanger 13. That is, the first housing 11 of the air conditioning component 10 has a first air inlet 111 and a second air outlet. The first air inlet 111 and the first air outlet 112 can be arranged opposite to each other or at a certain angle. When the air conditioning is in operation, the first air inlet 111 is connected to the kitchen space A through the air duct or directly. Under the action of the first fan 12, the air in the kitchen space A enters the first housing 11 and exchanges heat with the first heat exchanger 13 in the first housing 11 before being discharged through the first air outlet 112, thereby achieving cooling or heating of the air in the kitchen space A.

[0046] like Figure 5 and Figure 6 As shown, the air outlet component 20 is provided with a guide air duct 21. The inlet of the guide air duct 21 is connected to the first air outlet 112. The air outlet of the guide air duct 21 is suitable to be located in the kitchen. That is to say, the air outlet component 20 is connected to the first air outlet 112. The air in the kitchen space A after being processed in the air conditioning component 10 can flow back to the kitchen space A through the air outlet. The first air inlet 111, the first housing 11, the first air outlet 112, and the air outlet component 20 together define the "internal circulation channel" of the kitchen space A. During the flow of the air in the kitchen space A through the internal circulation channel, multiple components in the internal circulation channel perform the functions of the indoor unit to realize various air conditioning operations, including cooling and heating (and may also be disinfection, sterilization, etc.).

[0047] like Figures 7-9 As shown, the main unit 30 includes a second housing 31, in which a second fan 32, a compressor 33, and a second heat exchanger 34 are disposed. The first heat exchanger 13 and the second heat exchanger 34 are respectively connected to the compressor 33. The second housing 31 is provided with a first interface 311, an exhaust gas outlet 312, and a second air inlet 313. When the second fan 32 operates, the air entering from the second air inlet 313 exchanges heat with the second heat exchanger 34 and is then blown out from the exhaust gas outlet 312.

[0048] Specifically, the second housing 31 is provided with a first interface 311, an exhaust gas outlet 312 and a second air inlet 313. The second air inlet 313 is used to connect the air outside the kitchen space A (e.g., outdoors) with the second housing 31. The second fan 32 is used to introduce the air outside the kitchen space A into the second housing 31. The air outside the kitchen space A introduced into the second housing 31 exchanges heat with the second heat exchanger 34 to achieve the cooling of the second heat exchanger 34. During the heat exchange process, the air with increased temperature can be discharged through the exhaust gas outlet.

[0049] It is understandable that the second air inlet 313, the second housing 31, and the exhaust outlet form an "external circulation channel". During air conditioning operation, multiple components in the external circulation channel perform the functions of the outdoor unit and work in conjunction with the aforementioned internal circulation channel to achieve air conditioning operation.

[0050] The second heat exchanger 34 and the compressor 33 are both located inside the second housing 31. The second heat exchanger 34, the compressor 33 and the first heat exchanger 13 are connected. A reversing valve can be set in the compression circuit composed of the compressor 33, the first heat exchanger 13 and the second heat exchanger 34 to achieve cooling and heating functions by adjusting the direction of the reversing valve. Sterilization and disinfection operations of the internal circulation channel can also be achieved by setting sterilization units, disinfection units, etc. These are all things that those skilled in the art can easily think of, and will not be described in detail here.

[0051] Furthermore, the main unit 30 can also perform fume extraction. Specifically, the first interface 311 is connected to the kitchen space A. When fume extraction is required, the second fan 32 can introduce the gas in the kitchen space A into the second housing 31, and the air mixed with fumes in the kitchen space A can be discharged through the exhaust vent 312. The exhaust vent 312 can be connected to the building's fume extraction duct to avoid the discharged fumes from polluting the surrounding environment.

[0052] like Figures 10-12 As shown, the main unit of the range hood 40 includes a third housing 41, and a flue gas passage 411 is provided inside the third housing 41. The flue gas passage 411 has a flue gas inlet 412 and a flue gas outlet 413. The flue gas outlet 413 is connected to the first interface 311. The operation of the second fan 32 causes the oil fumes to be drawn in through the flue gas inlet 412 and discharged from the exhaust gas outlet 312.

[0053] Specifically, the first interface 311 is connected to the fume outlet, and the fume inlet is connected to the kitchen space A. Thus, when the second fan 32 rotates, the air in the kitchen space A can be introduced into the second housing 31 through the flue gas channel 411 and discharged from the kitchen space A through the exhaust gas outlet 312.

[0054] In summary, the kitchen air conditioning system 100 of the present invention, by setting up an air conditioning component 10 and a range hood main unit 40 connected to the main unit 30, can perform air conditioning operations such as cooling and heating of the kitchen space A when air conditioning is required, with the main unit 30 acting as the outdoor unit and the air conditioning component 10 acting as the indoor unit. When fume extraction is required, the main unit 30 is connected to the range hood main unit 40, and the suction force of the second fan 32 of the main unit 30 is used to exhaust the air mixed with fumes in the kitchen space A, thereby realizing the operation of the range hood.

[0055] The first fan 12 and the second fan 32 can be either an axial flow fan or a vortex fan, without any specific limitation. The first heat exchanger 13 is constructed as an evaporator, and the second heat exchanger 34 is constructed as a condenser.

[0056] It should be pointed out that, as Figure 1 As shown, during interior decoration, a suspended ceiling 300 is installed in kitchen space A. The kitchen air conditioning system 100 of this invention, with its main unit 30 and air conditioning unit 10 both located above the suspended ceiling 300, is not visible inside kitchen space A, thus offering a high level of aesthetics. Furthermore, the main unit 30 can function as an outdoor unit, eliminating the need for an outdoor unit installation location. This reduces the limitations imposed by installation space, improves assembly convenience, and minimizes space occupation. More importantly, during air conditioning operation, the second fan 32 circulates air in the external circulation channel; during fume extraction operation, the second fan 32 serves as the power source for fume extraction, achieving a high degree of integration between the range hood and the kitchen air conditioning system, thereby reducing costs.

[0057] It should be noted that kitchen space A is the location where the kitchen air conditioning system 100 of this application is installed. The air inside kitchen space A is the gas collected from kitchen space A, and the air outside kitchen space A is the gas collected from outside kitchen space A. The second air inlet 313 is preferably connected to the space outside the building (i.e., the outdoors).

[0058] According to an embodiment of the present invention, the kitchen air conditioning system 100, by setting a main unit 30, allows the main unit 30 to be selectively connected to the air conditioning unit 10 and the range hood main unit 40. On the one hand, the range hood and the kitchen air conditioning can be integrated, reducing the number of fans and thus reducing costs. On the other hand, there is no need to set up outdoor units, air supply panels and other components, which can improve the space occupation of the kitchen air conditioning system 100, reduce the space restrictions on product installation, and improve the assembly convenience of the kitchen air conditioning system 100.

[0059] like Figure 8 and Figure 9 As shown, according to some embodiments of the present invention, the second housing 31 includes a mounting housing 314 and a heat exchange housing 315. The mounting housing 314 is adapted to be mounted on a mounting surface. The compressor 33 and the second fan 32 are disposed inside the mounting housing 314. The first interface 311 is disposed on the bottom wall of the mounting housing 314, and the exhaust gas outlet 312 is disposed on the side wall of the mounting housing 314. The heat exchange housing 315 communicates with the mounting housing 314. The second heat exchanger 34 is disposed inside the heat exchange housing 315, and the second air inlet 313 is disposed on the side wall of the heat exchange housing 315.

[0060] It is understandable that a suspended ceiling 300 can be installed in kitchen space A. Above the suspended ceiling 300, there is a pipe for accommodating air conditioning component 10, main unit component 30, exhaust vent 312 and the duct connecting to the fume duct, second air inlet 313 and the duct connecting to the outside of kitchen space A, and first air inlet 111 and the duct connecting to the inside of kitchen space A.

[0061] The pipes connecting the exhaust outlet 312 to the fume duct, the pipe connecting the second air inlet 313 to the outside of the kitchen space A, and the pipe connecting the first air inlet 111 to the inside of the kitchen space A can all be constructed as flexible or rigid pipes, and this application does not make specific limitations on them.

[0062] Furthermore, at least a portion of the wall 200 above the ceiling 300 is formed as a mounting surface. The mounting housing 314 is generally plate-shaped or constructed as a mounting plate. One side wall of the mounting housing 314 is attached to and fixed to the wall 200. The bottom wall of the mounting housing 314 can also be attached to and fixed to the upper side of the ceiling 300. Components such as the second fan 32 and compressor 33 are all fixed to the mounting housing 314 by fasteners or snap-fit.

[0063] A first interface 311 is provided on the bottom wall of the mounting housing 314. The first interface 311 is used to connect the range hood main unit 40. A first clearance hole is provided on the ceiling 300 to facilitate the connection between the range hood main unit 40 and the first interface 311. The second air inlet 313 and the exhaust gas outlet 312 are respectively formed on the mounting housing 314 and the heat exchange housing 315. The heat exchange housing 315 has a second heat exchanger mounting position. The second heat exchanger 34 is set in the second heat exchanger mounting position. There are two second air inlets 313 and two exhaust gas outlets 312, located on opposite sides (front and rear sides or left and right sides) of the second housing 31.

[0064] In this way, on the one hand, the structure of the main unit 30 is more reasonable, and the positions of the second heat exchanger 34, compressor 33 and second fan 32 are more reasonable, which can ensure that the second heat exchanger 34 is directly opposite the second air inlet 313, thereby improving the heat exchange efficiency of the second heat exchanger 34 and improving the cooling and heating efficiency of the main unit 30 when performing air conditioning operation; on the other hand, the positions of the second air inlet 313 and the exhaust gas outlet 312 are more reasonable. When installing the kitchen air conditioning system 100, one of the two second air outlets and one of the two exhaust gas outlets 312 can be selected and connected to the corresponding pipes according to the needs, further improving the assembly convenience of the kitchen air conditioning system 100.

[0065] Specifically, the heat exchange housing 315 is provided with a receiving groove, which is constructed as a second heat exchanger mounting position. The second heat exchanger 34 can be installed in the receiving groove. The outside of the receiving groove defines a gas flow channel directly opposite the second heat exchanger 34. The air flowing in through the second air inlet 313 exchanges heat with the condenser in the gas flow channel directly opposite the second heat exchanger 34, effectively cooling the condenser and improving the sealing performance, preventing the air entering through the second air inlet 313 from flowing out into the kitchen space A.

[0066] exist Figure 2 and Figure 4 In the specific embodiment shown, the first fan 12 includes a plurality of impellers 121, and the outlet ends of the plurality of impellers 121 are all facing the first heat exchanger 13.

[0067] Specifically, the first fan 12 includes a drive motor and multiple fan wheels 121. In some embodiments, the multiple fan wheels 121 are coaxially arranged and driven by a single drive motor, making the structure of the air conditioning component 10 more compact, occupying less space, and reducing costs. In other embodiments, each fan wheel 121 is driven by a corresponding drive motor, so that the basic functions of the air conditioning component 10 can still be performed even if one drive motor fails, thereby improving the working stability of the air conditioning component 10.

[0068] Furthermore, in this invention, the outlet ends of multiple impellers 121 are all oriented towards the first heat exchanger 13. During air conditioning operation, it can be ensured that the air introduced into the kitchen space A within the first housing 11 by the first fan 12 can be formed into an airflow moving towards the first heat exchanger 13 under the action of the impellers 121, thereby improving the heat exchange effect between the first heat exchanger 13 and the air introduced into the kitchen space A by the first fan 12, improving the operational reliability of the kitchen air conditioning system 100 during air conditioning operation, and improving the cooling and heating efficiency.

[0069] like Figure 2 and Figure 3 As shown, in order to make reasonable use of the space above the ceiling 300 of the kitchen space A, the second housing 31 of the main unit 30 is arranged opposite to the first housing 11 of the air conditioning unit 10. The first heat exchanger 13, the compressor 33, and the second heat exchanger 34 are connected, but the first housing 11 and the second housing 31 are not connected to avoid air leakage, improve the working stability of the air conditioning and fume extraction of the kitchen air conditioning system 100 of the present invention, avoid the presence of oily fumes in the room during the air conditioning operation, and improve the user experience.

[0070] Meanwhile, the second housing 31 is fixed to the wall 200 by the mounting housing 314. The first housing 11 and the second housing 31 are arranged opposite to each other. Multiple fixing lugs can be set on the upper part of the first housing 11 along the circumference of the first housing 11 and fixed to the upper wall of the kitchen space A by fasteners. Alternatively, multiple fixing lugs can be set on the lower part of the first housing 11 and the air conditioning component 10 can be fixed by the fixing lugs and the ceiling 300 through the snap-fit ​​and plug-in structure.

[0071] exist Figure 2 In the specific embodiment shown, further, in the arrangement direction of the plurality of fan rotors 121, the electrical control component 14 of the air conditioning component 10 is located on one side of the first fan 12.

[0072] Specifically, multiple impellers 121 can be arranged sequentially in the width direction of the first housing 11, while the electronic control component 14 is located on one side of the first housing 11 in the width direction. This not only reduces the likelihood of interference between the impellers 121 and the electronic control component 14, and between the drive motor and the electronic control component 14, thus improving the ease of assembly of the air conditioning component 10, but also makes the placement of each component within the first housing 11 more reasonable, improving the space occupied by the air conditioning component 10 and effectively reducing the height of the air conditioning component 10. This makes it easier to place the air conditioning component 10 above the ceiling 300 in the kitchen space A, avoiding the possibility that the air conditioning component 10 is too tall to be assembled.

[0073] like Figure 3 , Figure 5 and Figure 6 As shown, according to some embodiments of the present invention, the first air outlet 112 is opened on the side wall of the first housing 11, and the guiding air duct 21 includes a first air duct 211 and a second air duct 212 that are connected. The first air duct 211 extends horizontally and cooperates with the first air outlet 112, the second air duct 212 extends vertically, and the bottom wall of the second air duct 212 is provided with an air duct outlet.

[0074] Specifically, a second clearance hole needs to be provided on the ceiling 300 to avoid the guide air duct 21. The first air duct 211 of the air outlet component 20 passes through the second clearance hole to extend into the space above the ceiling 300. The first air duct 211 extends horizontally. The first air outlet 112 of the first housing 11 is located on the side of the first housing 11 adjacent to the second housing 31. The first air duct 211 is located between the first housing 11 and the second housing 31 to separate them. The first air outlet 112 is connected to the first air duct 211, and the first air duct 211 is connected to the second air duct 212. The air duct outlet is located on the second air duct 212 to exhaust the air in the kitchen space A, which has been treated by the air conditioning component 10, to the kitchen space A through the air duct outlet. In this way, the position of the air duct outlet is more reasonable, located at the bottom of the second air duct 212, which can improve the air outlet effect.

[0075] It is understandable that the first air duct 211 and the second air duct 212 are roughly L-shaped after being connected, so as to connect the air conditioning unit 10 located in the space above the suspended ceiling 300 with the space below the suspended ceiling 300, and thus, as Figure 6 As shown, a transition duct can be provided between the first air duct 211 and the second air duct 212. The transition duct is used to connect the first air duct 211 and the second air duct 212. The transition duct can be constructed as a flexible component to eliminate assembly errors between the first air duct 211 and the second air duct 212. Even when the side or bottom wall of the first air duct 211 intersects with the top of the second air duct 212, the two can still be connected through the transition duct, further improving assembly convenience and enhancing the applicability of the kitchen air conditioning system 100 of this embodiment.

[0076] like Figure 10 and Figure 12 As shown, in some embodiments, the top of the third housing 41 is provided with an annular surrounding plate 414, and the surrounding plate 414 and the outer peripheral wall of the third housing 41 are provided with an insertion space. The first interface 311 of the second housing 31 is inserted into the insertion space so that the flue gas outlet 413 and the first interface 311 are connected.

[0077] Specifically, the first interface 311 is inserted into the third housing 41. The top of the third housing 41 has a flue gas outlet 413 defined by the third housing 41 and a surrounding plate 414 whose projected area in the height direction of the third housing 41 is larger than the projected area of ​​the flue gas outlet 413. The flue gas outlet 413 and the surrounding plate 414 define an annular insertion space. After the first interface 311 is inserted into the third housing 41 in the annular insertion space, the side wall of the surrounding plate 414 is fitted with the side wall of the second housing 31 to achieve a seal, thereby improving the sealing effect between the third housing 41 and the second housing 31. This prevents the space entering the second housing 31 from escaping through the gap between the second housing 31 and the third housing 41 during the fume extraction operation, ensuring stable fume extraction efficiency and improving the working stability of the fume extraction operation.

[0078] It is understood that the enclosure 414 can at least partially protrude from the top surface of the third housing 41, so that during the assembly of the second housing 31 and the third housing 41, the portion of the enclosure 414 that protrudes above the top surface of the third housing 41 can serve as a height adjustment allowance, thereby enabling the adjustment of the setting height of the range hood main unit 40, further improving the assembly convenience and applicability of the kitchen air conditioning system 100.

[0079] like Figure 11 As shown, in some embodiments, the third housing 41 is formed of a metallic material to condense oil fumes.

[0080] Specifically, the third housing 41 extends vertically, with its upper end connected to the second housing 31 and its lower end and at least part of its side connected to the kitchen space A. This allows the fumes to enter the second housing 31 more quickly through the third housing 41, increasing the suction speed and improving the fume extraction efficiency. This enhances the user experience of the kitchen air conditioning system 100. Furthermore, the third housing 41 is made of metal, which has a lower surface temperature. The fact that the third housing 41 and the air outlet component 20 are positioned vertically relative to each other ensures that the temperature of the third housing 41 remains low. This lower temperature ensures that the small droplets of fumes in the second air duct 212 are cooled and can then settle downwards.

[0081] Therefore, it can be understood that the bottom of the third housing 41 is provided with an oil collection groove 45. After the oil fumes enter the third housing 41, at least part of them will be deposited in the oil collection groove 45. The oil fumes droplets with higher temperature will continue to flow towards the second housing 31 with the airflow. During the flow, the third housing 41, which is constructed as a metal part, will cool down and can settle into the oil collection groove 45 under the action of gravity.

[0082] In this way, by constructing the third housing 41 as a metal part, not only can the oil fume settling effect be improved to effectively collect oil fumes, but the cleaning of the third housing 41 is also simpler and easier, and the amount of oil fume accumulated in the second housing 31 can be reduced, making the cleaning of the second housing 31 and the components inside the second housing 31 simpler and more convenient.

[0083] The oil collection tank 45 has a buckle at its end, and the extension length of the oil collection tank 45 is the same as the extension length of the third housing 41. The end of the third housing 41 has a slot that engages with the buckle. The oil collection tank 45 and the third housing 41 engage with each other, making the disassembly and assembly of the oil collection tank 45 simpler and more convenient. As a component that needs to be frequently disassembled to clean up oil and perform cleaning, the easier disassembly and assembly of the oil collection tank 45 can also improve the user experience.

[0084] Furthermore, a liquid level indicator can be installed on the oil collection tank 45. At least a portion of the oil collection tank 45 can be constructed to be internally visible, with corresponding scale lines on the area to facilitate user observation of the oil accumulation in the oil collection tank 45. Alternatively, the liquid level indicator can be constructed as a liquid level sensor. When the liquid level in the oil collection tank 45 is too high and needs to be cleaned, the kitchen air conditioning system 100 will issue a prompt to inform the user that the oil accumulation in the oil collection tank 45 needs to be cleaned.

[0085] It is understood that in some embodiments, an oleophobic coating can be applied to the surfaces of the second housing 31, the third housing 41, and the components inside the second housing 31 to reduce the accumulation of oil fumes on the inner surface of the second housing 31, the inner surface of the third housing 41, the compressor 33, the second fan 32, and other components, thereby further improving the ease of cleaning the main unit 30 and the range hood main unit 40. The higher the ease of cleaning the range hood main unit 40, the better the user experience.

[0086] In some embodiments, a cold storage section may be provided in the third housing 41. The cold storage section may be selectively connected to the second heat exchanger 34 or the compressor 33. When the kitchen air conditioning system 100 is performing fume extraction, the second heat exchanger 34 or the compressor 33 stores cold in the cold storage section. The cold energy in the cold storage section can act on the guide air duct 21 of the third housing 41 to cool down the fumes entering the guide air duct 21, so that the fumes can settle in large quantities and improve the fume accumulation effect of the oil collection tank 45.

[0087] like Figure 11 As shown, a grille 44 is provided on the open areas on the sides and bottom of the third housing 41 for absorbing oil fumes. The grille 44 can filter the oil fumes to prevent foreign objects from entering the third housing 41 or the second housing 31, thus improving the stability of operation. The grille 44 is made of metal, which can also initially improve the settling effect of oil fumes. In addition, the grille 44 has multiple rows and columns of through holes, which can increase the contact area between the oil fumes and the grille 44 to further improve the settling effect of oil fumes.

[0088] Preferably, the grille 44 is constructed as a corrosion-resistant metal part and is detachably mounted on the third housing 41, for example, by snap-fit ​​or plug-in connection, so that the grille 44 is easier and more convenient to install and remove on the third housing 41, thereby improving the ease of installation and removal and making the cleaning of the grille 44 simpler and more convenient.

[0089] like Figure 12 As shown, in some embodiments, the kitchen air conditioning system 100 also includes an opening / closing member 42 for opening or closing the flue gas inlet 412.

[0090] Specifically, the top of the opening and closing component 42 is pivotally mounted on the third housing 41, and the bottom can be selectively rotated to open or close the opening area of ​​the third housing 41 for collecting oil fumes. A grille 44 is provided on the opening area. The opening and closing component 42 can selectively open or cover the grille 44 to improve the aesthetics of the kitchen air conditioning system 100 when the opening and closing component 42 is not open. After the opening and closing component 42 is opened, since the third housing 41 is located on the side above the stove, and the opening and closing component 42 is at least partially opposite the pots and pans above the stove, it can block some of the splashed oil droplets, reduce the amount of oil droplets splashing onto the vicinity of the stove, and reduce the cleaning workload for the user.

[0091] It is understood that the surface of the opening and closing component 42 is preferably also coated with an oleophobic coating, and the top of the opening and closing component 42 can be pivotally connected to the third housing 41 through an arc-shaped support arm. The two ends of the arc-shaped support arm are respectively fixed to the upper end of the opening and closing component 42 and the third housing 41. The arc-shaped part of the arc-shaped support arm is used to avoid the third housing 41 during the opening and closing process of the opening and closing component 42, so as to ensure that the opening and closing component 42 will not interfere with the surrounding components during the opening and closing process, and can ensure that the outer surface of the opening and closing component 42 is flush with the outer surface of the third housing 41 after the opening and closing component 42 is closed, so as to effectively improve the aesthetics of the kitchen air conditioning system 100.

[0092] Furthermore, a driving component can be installed inside the third housing 41, and the opening and closing component 42 can be moved by the driving component to realize the automatic opening and closing of the opening and closing component 42, thereby further improving the ease of use of the kitchen air conditioning system 100.

[0093] like Figure 6 As shown, in some embodiments, the kitchen air conditioning system 100 further includes an air guide assembly 50, which is rotatably disposed at the air duct outlet to change the air outlet direction. Thus, the air outlet direction can be adjusted by rotating the air guide assembly, allowing the user to adjust the air outlet direction of the kitchen air conditioning system 100 according to their needs, further improving the user experience of the kitchen air conditioning system 100.

[0094] It is understood that in some embodiments, the air guide assembly 50 is configured as a manually adjustable component, which can be manually adjusted by the user according to the usage requirements. In other embodiments, the air guide assembly 50 is configured as an electrically adjustable component. The air guide assembly 50 is rotatably disposed below the second air duct 212 of the air guide assembly via a drive member and / or a transmission member, so that when the air guide assembly 50 needs to be adjusted, the user issues a command via a remote control or a voice command, and the air guide assembly 50 is adjusted accordingly.

[0095] exist Figure 6 In the specific embodiment shown, the air guiding assembly 50 includes a first air guiding plate 51 and a plurality of second air guiding parts 52. The first air guiding plate 51 is rotatably disposed at the air duct outlet to open or close the air duct outlet. The plurality of second air guiding parts 52 are spaced apart on the first air guiding plate 51. When the first air guiding plate 51 closes the air duct outlet, the plurality of second air guiding parts 52 are located in the air guiding duct 21. Each second air guiding part 52 and the first air guiding plate 51 define an air guiding channel.

[0096] In other words, the first air guide plate 51 can block the air duct outlet and, after rotation, gradually switch the air duct outlet from at least partially open to fully open, and can then gradually switch it from fully open to closed. The air volume at the air duct outlet can be adjusted by setting the first air guide plate 51. A second air guide section 52 is then set on the first air guide plate 51. The second air guide section 52 can be constructed as multiple air guide fan blades. The air outlet angle of the air duct outlet can be adjusted by adjusting the angle between the air guide fan blades and the first air guide plate 51.

[0097] Of course, the structure of the air guide assembly 50 of the present invention is not limited to this. In some other embodiments, the air guide assembly 50 includes: a plurality of first air guide blades and a plurality of second air guide blades. The plurality of first air guide blades are disposed on a first shaft, which is disposed on a third housing 41. The plurality of first air guide blades can rotate relative to the first shaft so that the plurality of first blades can rotate between a first state of blocking the air duct outlet and a second state perpendicular to the air duct outlet to adjust the air volume. The plurality of second air guide blades are disposed in the second air duct 212 and are disposed opposite to the first air guide blades. The plurality of second air guide blades are rotatably disposed on the second shaft to adjust the air outlet angle of the air duct outlet.

[0098] Understandably, the air outlet component 20 is fixed to the second housing 31. In other words, the first housing 11 has a first air outlet 112 formed on the side facing the second housing 31, the first air duct 211 of the air outlet component 20 extends into the first clearance opening and communicates with the first air outlet 112, and the portion of the air outlet component 20 defining the first air duct 211 is located between the first housing 11 and the second housing 31, so that the side plate of this portion is fixed to the second housing 31, that is, the air outlet component 20 is fixed to the adjacent second housing 31, which improves the convenience of fixing, and the length of the fasteners used to fix the second housing 31 can be set to be smaller, which can further reduce costs.

[0099] like Figure 10 and Figure 11 As shown, the kitchen air conditioning system 100 also includes a control panel 43, which is located on the third housing 41. The control panel 43 is electrically connected to the air conditioning component 10 and the main unit component 30 to control the operation of the air conditioning component 10 and the main unit component 30.

[0100] In this way, the control panel 43 is located on the upper side of the stove and is spaced apart from the stove, making the position of the control panel 43 more reasonable and convenient for users to operate the control panel 43 to achieve the corresponding functions. At the same time, during the fume extraction operation, the opening and closing part 42 can separate the control panel 43 from the stove to avoid oil droplets splashing onto the control panel 43, reducing the user's cleaning workload. At the same time, the control panel 43 is less likely to accumulate oil stains, which can also improve the user experience.
