[0053] The kitchen air conditioning system 1 according to the embodiments of the present application will be described below with reference to the accompanying drawings.

[0054] As shown in Figs. 1 and 2, the kitchen air conditioning system 1 according to the embodiments of the present application comprises an air conditioning main machine 11, a range hood main machine 12 and a fan main machine 13, wherein the air conditioning main machine 11 is used to generate low-temperature air flow, the range hood main machine 12 is used to suck oil fume, and the fan main machine 13 can provide power for the flow of the air flow generated in the air conditioning main machine 11 and can also provide power for the suction of the oil fume by the range hood main machine 12. Figure 1 Figure 2 Figure 7 Figure 10 As shown in Figs. 1 and 2, the kitchen air conditioning system 1 according to the embodiments of the present application comprises an air conditioning main machine 11, a range hood main machine 12 and a fan main machine 13, wherein the air conditioning main machine 11 is used to generate low-temperature air flow, the range hood main machine 12 is used to suck oil fume, and the fan main machine 13 can provide power for the flow of the air flow generated in the air conditioning main machine 11 and can also provide power for the suction of the oil fume by the range hood main machine 12.

[0055] Further, a condensate water discharge outlet is arranged on the first machine shell 111 to discharge the condensate water.

[0056] Further, a plurality of supporting legs are arranged on the bottom wall of the first machine shell 111, and the supporting legs are used to connect a ceiling to fix the first machine shell 111 on the ceiling.

[0057] As shown in Figs. 1 and 2, the kitchen air conditioning system 1 according to the embodiments of the present application comprises an air conditioning main machine 11, a range hood main machine 12 and a fan main machine 13, wherein the air conditioning main machine 11 is used to generate low-temperature air flow, the range hood main machine 12 is used to suck oil fume, and the fan main machine 13 can provide power for the flow of the air flow generated in the air conditioning main machine 11 and can also provide power for the suction of the oil fume by the range hood main machine 12. Figure 10 As shown in Figs. 1 and 2, the kitchen air conditioning system 1 according to the embodiments of the present application comprises an air conditioning main machine 11, a range hood main machine 12 and a fan main machine 13, wherein the air conditioning main machine 11 is used to generate low-temperature air flow, the range hood main machine 12 is used to suck oil fume, and the fan main machine 13 can provide power for the flow of the air flow generated in the air conditioning main machine 11 and can also provide power for the suction of the oil fume by the range hood main machine 12.The first heat exchange chamber 1101 has a first air return port 1102 and a first air outlet 1103, and the second heat exchange chamber 1104 has a second air return port 1105 and a second air outlet 1106. The second air return port 1105 can be connected with the indoor air, and the air in the kitchen can be introduced into the second air return port 1105 to be introduced into the second heat exchange chamber 1104 to exchange heat with the second heat exchanger 1112, so as to continuously reduce the temperature of the air in the kitchen. The first air return port 1102 can be communicated with the outdoor air to introduce the outdoor air into the first chamber 1304 to exchange heat with the first heat exchanger 1111 to exchange heat of the refrigerant to the outdoor air. A filter screen is arranged at the first air return port 1102 to preliminarily filter the outdoor air.​​

[0058] The first shell 111 of the air conditioner host 11 integrates the first heat exchanger 1111 and the second heat exchanger 1112, improves the integration of the air conditioner host 11, does not need to set an air conditioner outdoor unit, reduces the number of parts of the kitchen air conditioning system 1, and makes the installation of the kitchen air conditioning system 1 more simple and convenient.

[0059] Further, the third shell 131 is arranged on the fan host 13, and a fan assembly is arranged in the third shell 131. Rotation of a fan wheel in the fan assembly can provide power for air flow. The third shell 131 is provided with a first air inlet 1301, a second air inlet 1302, and a common air outlet 1303. The fan wheel can generate negative pressure at the first air inlet 1301 and the second air inlet 1302 during rotation, so as to suck air into the third shell 131. The negative pressure generated by the fan host 13 can provide power for air flow in the first heat exchange chamber 1101 of the air conditioner host 11 and can also provide power for air flow in the oil fume passage 1211 in the range hood host 12. Therefore, the fan host 13 can integrate the power provided for air flow in the range hood host 12 and the first heat exchange chamber 1101 of the air conditioner host 11.

[0060] The third shell 131 is provided with the first air inlet 1301, the second air inlet 1302, and the common air outlet 1303. The first air outlet 1103 is connected to the first air inlet 1301, so as to guide air that has been heat-exchanged in the first heat exchange chamber 1101 to the third shell 131 under the action of the fan wheel. The second air inlet 1302 is connected to the oil fume outlet 1202, so as to guide oil fume sucked by the oil fume inlet 1201 in the range hood host 12 to flow under the action of the fan wheel and enter the third shell 131 through the second air inlet 1302. In the third shell 131, air that has been heat-exchanged in the first chamber 1304 and has a high temperature is mixed with oil fume sucked by the range hood host 12, and is discharged through the common air outlet 1303 to be guided to the outside.

[0061] The air conditioner air outlet 1204 is arranged on the smoke machine main body 12. The indoor air of the kitchen can be heat-exchanged with the second heat exchanger 1112 in the second heat exchange chamber 1104 after passing through the second heat exchange chamber 1104, so as to reduce the temperature of the airflow. The airflow after heat exchange is connected with the air conditioner air inlet 1203 of the heat exchange air duct 1212 arranged in the second machine shell 121 through the second air outlet 1106. The airflow with reduced temperature is introduced into the second machine shell 121 and is blown out through the air conditioner air outlet 1204 arranged on the second machine shell 121, so that the air conditioner air outlet 1204 is arranged on the smoke machine main body 12, the air outlet directly blows to the user, and more direct cold air is provided for the user. The temperature around the user is effectively reduced, so that the user obtains a better cooking environment. The cold air generated by the air conditioner main body 11 can be directly blown to the user through the air conditioner air outlet 1204 arranged on the second machine shell 121. The air outlet position is located in the cooking area of the user, and the temperature of the cooking area of the user can be more directly reduced.

[0062] According to the kitchen air conditioner system 1, the functions of refrigeration and smoke suction are integrated by arranging the air conditioner main body 11, the smoke machine main body 12 and the fan main body 13. The low-temperature airflow generated by the air conditioner main body 11 is blown out through the air conditioner air outlet 1204 arranged on the smoke machine main body 12. The air outlet of the kitchen air conditioner system 1 is integrated and arranged on the smoke machine main body 12, so that the airflow can be more directly blown to the user. Meanwhile, the fan main body 13 simultaneously acts on the air conditioner main body 11 and the smoke machine main body 12, and the integration degree of the air outlet air conditioner system is improved.

[0063] According to an embodiment of the present application, the second machine shell 121 further comprises a condensation channel 1213. The condensation channel 1213 is in communication with the second air outlet 1106. The second machine shell 121 comprises a shared shell body for separating the condensation channel 1213 from the smoke oil channel 1211. The condensation channel 1213 and the smoke oil channel 1211 are heat-exchanged through the shared shell body to condense the oil smoke in the smoke oil channel 1211.

[0064] The condensation channel 1213 within the range hood main unit 12 is designed for the flow of low-temperature airflow. The condensation channel 1213 is connected to the second air outlet 1106 of the air conditioning unit 11, allowing the condensed airflow generated by the air conditioning unit 11 to enter the condensation channel 1213. A common casing is provided between the condensation channel 1213 and the grease channel 1211, facilitating heat exchange between the airflow in the condensation channel 1213 and the grease channel 1211. Under the influence of the airflow in the condensation channel 1213, the temperature of the common casing is significantly lower than the temperature of the airflow in the grease channel 1211. This allows the grease to exchange heat with the inner wall of the grease channel 1211 as it flows through, lowering its temperature and causing it to condense on the inner wall. This condensation of grease within the grease channel 1211 improves the filtration efficiency of the range hood main unit 12 and enhances its grease extraction capacity.

[0065] According to one embodiment of the present invention, the condensing channel 1213 can be connected to the heat exchange duct 1212. The condensing channel 1213 can be located downstream of the heat exchange duct. The low-temperature airflow generated by the air conditioning unit 11 first enters the heat exchange duct 1212 and is discharged into the kitchen through the air conditioning outlet 1204 on the second casing 121 to cool the indoor temperature of the kitchen. The low-temperature airflow in the heat exchange duct 1212 has a low temperature and a good cooling effect.

[0066] The condensation channel 1213 is located downstream of the heat exchange duct 1212. When the user activates the condensation function for the e-liquid, the condensation channel 1213 is connected to the heat exchange duct 1212. The condensation channel 1213 introduces a portion of the low-temperature airflow to lower the temperature of the shared housing, thereby condensing the e-liquid in the e-liquid channel 1211. By placing the condensation channel 1213 downstream of the heat exchange duct 1212, the user's cooling needs can be met first before condensing the fumes in the e-liquid channel 1211.

[0067] In one specific embodiment of the present invention, the air conditioning vent 1204 located on the front panel of the second housing can be configured as an elongated vent. This vent can extend in the width direction of the second housing 121 of the range hood main unit 12 to increase the air outlet width and improve the area covered by the air conditioning vent 1204. Alternatively, the air conditioning vent 1204 on the front panel of the second housing can be configured as a rectangular hole extending laterally on the front panel of the second housing. The airflow after passing through the first heat exchange chamber 1101 is guided through the air conditioning vent 1204 to the front area directly opposite the range hood main unit 12, where heat is exchanged to improve the ambient temperature of the front area.

[0068] The air conditioning vents 1204 on the left and right sides of the second housing 121 of the range hood main unit 12 can also be constructed as rectangular vents. The two air conditioning vents 1204 on the left and right sides of the second housing 121 of the range hood main unit 12 extend in the height direction of the second housing 121 of the range hood main unit 12 and open to both sides, which can further expand the air outlet range that the air conditioning vents 1204 on the range hood main unit 12 can cover. The air conditioning vents 1204 on the left and right sides can be selectively closed.

[0069] Multiple cooktops can be installed directly below the range hood main unit 12. The air conditioning vents 1204 located on the left and right side panels can be turned on or off depending on the location of the cooktop. For example, when the cooktop on the left is turned on, the air conditioning vent 1204 on the left side panel can be turned on to improve the ambient temperature of the corresponding area.

[0070] In one embodiment of the present invention, each air conditioner outlet 1204 is provided with an air guide plate 1205 for adjusting the air outlet direction. The air guide plate 1205 may include a first air guide plate, a second air guide plate, and a third air guide plate. The first air guide plate includes a pivot portion adapted to be connected to a driving member. The output end of the driving member is adapted to drive the pivot portion to rotate. It should be noted that during the rotation of the pivot portion by the driving member, the rotation axis of the output shaft of the driving member is the same as the extension direction of the air conditioner outlet 1204 on the front panel of the second housing 121 of the range hood main unit 12. An air guide portion is provided on the side of the pivot portion facing away from the air conditioner outlet 1204. The air guide portion is constructed as an arc shape protruding away from the air conditioner outlet 1204 to make the appearance of the range hood main unit 12 more rounded and aesthetically pleasing. When the driving component drives the first air guide plate to rotate, at least a portion of the first air guide plate can rotate to the air conditioning outlet 1204 on the front of the second housing 121 of the range hood main unit 12, and the air conditioning outlet 1204 on the front of the second housing 121 of the range hood main unit 12 opens, while the first air guide plate is hidden.

[0071] Furthermore, since the outer side of the air guide plate of the first air guide plate is an arc shape protruding from the front panel of the second housing 121 of the range hood main unit 12, the driving component can adjust the air outlet area of ​​the air conditioning outlet 1204 located on the front of the second housing 121 of the range hood main unit 12 by changing the pivot angle of the first air guide plate, and the user can adjust the rotation angle of the first air guide plate.

[0072] Air conditioning vents 1204 are provided on both the left and right sides of the second housing. A drive unit for driving the second and third air guide plates can be provided inside the air conditioning vents 1204. The second and third air guide plates can be constructed as rectangular plates. The drive unit is constructed as a drive motor and is located on the lower side of the corresponding air conditioning vent 1204. The output shaft of the drive motor can be connected to the corresponding second and third air guide plates. The output shaft of the drive motor is in the same direction as the extension of the corresponding second and third air guide plates, so as to drive the second and third air guide plates to open in a direction away from each other, thereby increasing the air outlet width of the main unit 12 of the range hood.

[0073] Similarly, the rotation angles of the second and third air guide plates can be selectively adjusted. By controlling the drive motors that drive the second and third air guide plates, the width of the air outlet range of the main unit 12 of the range hood can be adaptively adjusted, and can be adjusted according to the user's selection.

[0074] According to one embodiment of the present invention, the kitchen air conditioning system 11 further includes a switch panel assembly for adjusting the size of the fume inlet 1201. The switch panel assembly is movably disposed on the second housing 121 of the range hood main unit 12. The switch panel assembly can be disposed on the front side of the second housing 121 of the range hood main unit 12. The fume inlet 1201 is disposed on the front side of the front panel of the second housing 121 of the range hood main unit 12. The fume inlet 1201 may include a plurality of elongated holes penetrating the front panel of the second housing 121 of the range hood main unit 12. Each elongated hole extends in the height direction and is spaced apart in the width direction of the front panel of the second housing 121 of the range hood main unit 12. At least a portion of the elongated holes extend to the lower end face of the second housing 121 of the range hood main unit 12.

[0075] In one specific embodiment of the present invention, a switch panel assembly is rotatably disposed on the second housing 121 of the range hood main unit 12. The switch panel assembly has an open state and a closed state. When the switch panel assembly is in the closed state, it covers the front of the second housing 121 of the range hood main unit 12, thereby covering the fume inlet 1201 on the front of the second housing 121 of the range hood main unit 12, leaving only the fume inlet 1201 located on the lower end face of the second housing 121 of the range hood main unit 12. When the switch panel assembly is in the closed state, it can be adapted to a corresponding state with a smaller amount of fume, and keeping the switch panel in the closed state can reduce the space occupied by the range hood main unit 12.

[0076] like Figures 11-13As shown, according to one embodiment of the present invention, a heat dissipation port 1206 communicating with the condensation channel 1213 is provided on the second housing 121. The heat dissipation port 1206 is used to discharge the gas after heat exchange with the grease channel 1211, so as to avoid the air pressure in the condensation channel 1213 from continuously increasing, which would prevent the airflow from entering the condensation channel 1213 for condensation. At the same time, when the airflow in the condensation channel 1213 continuously gathers, the airflow in the condensation channel 1213 may backflow towards the air conditioner outlet 1204, causing the temperature of the air outlet at the air conditioner outlet 1204 to rise, affecting the user's experience.

[0077] The heat dissipation vent 1206 provided on the second housing 121 can open when the airflow in the condensation channel 1213 meets certain conditions, so as to reduce the pressure in the condensation channel 1213 and thus ensure smooth airflow.

[0078] According to one embodiment of the present invention, a pressure control switch door is provided on the second housing 121. The pressure control switch door controls the opening and closing of the heat dissipation port 1206 according to the pressure in the condensation channel 1213. After the pressure of the low-temperature air in the condensation channel 1213 reaches a preset value, the low-temperature air pushes open the pressure control switch door 103 to prevent the airflow in the condensation channel 1213 from affecting the airflow in the heat exchange duct 1212. When the pressure control switch door is closed, the low-temperature air exchanges heat fully with the e-liquid in the condensation channel 1213 to prolong the heat exchange time between the low-temperature air and the e-liquid and reduce the cold loss caused by the outflow of low-temperature air.

[0079] According to one embodiment of the present invention, the pressure-controlled switch door 103 includes a door panel and an elastic structure. The door panel is rotatably disposed at the outlet of the condensation channel 1213. The door panel has a door panel shaft, which is rotatably connected to the inner wall of the condensation channel 1213. The elastic structure is sleeved on the door panel shaft. The elastic structure can be constructed as a spring. The first end of the elastic structure elastically presses against the inner wall surface of the condensation channel 1213, and the second end of the elastic structure elastically presses against the inner wall surface of the door panel. After the pressure in the condensation channel 1213 reaches a preset pressure, the pressure exerted by the airflow on the door panel is greater than the spring force, which can open the door panel to allow airflow. After the airflow flows, the airflow pressure in the condensation channel 1213 is lost, and the pressure switch door is further closed to avoid further loss of airflow in the condensation channel 1213. This allows the gas in the condensation channel 1213 to fully exchange heat with the oil fumes in the oil fume channel 1211, improving the utilization efficiency of the low-temperature airflow and reducing the loss of cooling capacity.

[0080] like Figures 17-20As shown, according to an embodiment of the present invention, the third housing 131 is divided into two parts: a wind-gathering housing 1311 and a wind-supplying housing 1312. The wind-gathering housing 1311 is provided with a fan assembly 14 for collecting the airflow from the air conditioning unit 11 and the grease from the range hood unit 12, and then sending out the collected airflow.

[0081] In the air-collecting housing 1311, a first air inlet 1301 is provided to allow airflow from the air conditioning unit 11 to directly enter the air-collecting housing 1311. The air-collecting housing 1311 is also provided with a first connecting port 13111 and a second connecting port 13112 for connecting to the air supply housing 1312. The first connecting port 13111 is used to connect the second air inlet 1302 to the air-collecting housing 1311, so that the grease from the range hood unit 12 can enter the air-collecting housing 1311. The second connecting port 13112 can be connected to the common air outlet 1303 to discharge the collected airflow.

[0082] In the air supply housing 1312, the air supply housing 1312 has a first chamber 1304 and a second chamber 1305 that are separated from each other. The first chamber 1304 is provided with a third connecting port 13121 and a second air inlet 1302. The oil fumes from the range hood 12 enter the first chamber 1304 through the second air inlet 1302, and after passing through the first chamber 1304, they enter the air gathering housing 1311 through the first connecting port 13111, where they converge with the airflow from the air conditioning unit 11 and flow under the action of the impeller in the air gathering housing 1311.

[0083] The air supply housing 1312 is also provided with a second chamber 1305 that is spaced apart from the first chamber 1304. The second chamber 1305 is provided with a fourth connecting port 13122 and a common air outlet 1303. The fourth connecting port 13122 is used to connect the air gathering housing 1311 and the air supply housing 1312. The second chamber 1305 can guide the gathered airflow to the common air outlet 1303.

[0084] The first chamber 1304 and the second chamber 1305 are integrated on the air supply housing 1312, so that the third housing 131 can collect the air from the air conditioner and the exhaust from the smoke and oil, and the collected airflow is discharged by the second chamber 1305, which simplifies the structure of the air duct and reduces the cost of the kitchen air conditioning system 1.

[0085] The fan assembly 14 installed inside the air-collecting housing 1311 can be a centrifugal fan, which has the characteristics of axial air inlet and lateral air outlet. In the air-collecting housing 1311, the first air inlet 1301 and the third connecting port 13121 are arranged opposite each other. The fan assembly 14 can be spaced apart from the inner side wall of the air-collecting housing 1311 to form a channel suitable for airflow. This channel can be located on the upper or lower side of the fan assembly 14, and the axial air inlet 142142 of the axial flow fan is directly opposite this channel. The first air inlet 1301 and the third connecting port 13121 are located on the air-collecting housing 1311 and face the channel, thereby converging the airflow from the air conditioning unit 11 and the airflow from the range hood unit 12 into the channel. Under the action of the axial flow fan, the airflow in the channel is drawn in to achieve the convergence of airflow. The converged airflow is discharged into the air supply housing 1312 through the second connecting port 13112 on the air-collecting housing 1311, and then discharged through the common air outlet 1303 of the air supply housing 1312.

[0086] The first air inlet 1301 and the first connecting port 13111 are positioned facing each other, so that the airflow from the air conditioning unit 11 and the oil fumes from the range hood unit 12 are gathered in the air-collecting housing 1311. The negative pressure generated by the axial flow fan can more effectively draw the airflow in the channel, thereby improving the efficiency of the kitchen air conditioning system 1.

[0087] According to one embodiment of the present invention, the fan assembly 14 includes a volute 141 and a centrifugal impeller 144. An impeller cavity is formed inside the volute 141. The volute 141 is open on one side facing the air gathering cavity to form an axial air inlet 142142. The axial air inlet 142142 is directly opposite to the aforementioned channel to effectively draw in airflow from two different sources within the channel. A lateral air outlet is also provided on the volute 141, which is directly opposite to the second connecting port 13112, so that the gathered airflow is discharged through the lateral air outlet. The discharged airflow enters the second chamber 1305 of the air supply housing 1312 through the second connecting port 13112 and is discharged to the outside through the common air outlet 1303.

[0088] Centrifugal impeller 144 is disposed inside the impeller cavity. The rotation axis of centrifugal impeller 144 is perpendicular to the plane where the first air inlet 1301 and the first connecting port 13111 are located, so that the axial air intake efficiency of centrifugal impeller 144 is high, the exhaust efficiency of fan assembly 14 is improved, and the energy consumption of kitchen air conditioning system 1 is reduced.

[0089] According to one embodiment of the present invention, there are two public air outlets 1303 symmetrically arranged on the air supply housing 1312. The public air outlets 1303 are used to collect the airflow from the air conditioning unit 11 and the exhaust gas from the range hood unit 12 and discharge them into the public flue. Since the flue locations are different in different kitchens, the public air outlets 1303 are symmetrically arranged on the air supply housing 1312. During the installation of the kitchen air conditioning system 1, the corresponding public air outlet 1303 is selected according to the location of the flue and connected to the flue. Then, the other public air outlet 1303 is closed to improve the applicability of the kitchen air conditioning system 1.

[0090] According to one embodiment of the present invention, the fume outlet 1202 is provided with a second valve for opening or closing the fume outlet 1202. The fume outlet 1202 is used to connect the fume channel 1211 with the first chamber 1304 in the air supply housing 1312 of the fan host 13. The second valve at the fume outlet 1202 can be used to select to open or close the fume outlet 1202. When the fume outlet 1202 is closed, the fume extraction function of the fan host 12 is in the off state, and the fumes in the fume channel 1211 will not enter the fan host 13. The purpose of the second valve is to prevent the fumes in the fume channel 1211 from entering the air supply housing 1312 of the fan host 13, so as to avoid the fumes from entering the air supply housing 1312 and the air collection housing 1311 into the air conditioning host 11, and to avoid the occurrence of cross-contamination of fumes.

[0091] In addition, after the air conditioning unit 11 is turned on separately, in order to prevent some airflow from entering the oil fume channel 1211 through the oil fume outlet 1202, the second valve can also ensure that the high-temperature airflow after heat exchange will not enter the room through the oil fume channel 1211.

[0092] According to one embodiment of the present invention, the first air inlet 1301 is provided with a first valve for opening or closing the first air inlet 1301. The first air inlet 1301 is an interface connecting the first heat exchange chamber 1101 of the air conditioning unit 11 and the air-collecting housing 1311 of the fan unit 13. The first valve is provided on the first air inlet 1301 to control the opening and closing of the first air inlet 1301, thereby preventing the airflow in the air-collecting housing 1311 of the fan unit 13 from flowing back into the air conditioning unit 11.

[0093] For example, when the range hood 12 is used alone and the air conditioner 11 is not turned on, the range hood 12 draws in oil fumes through the oil fume channel 1211, and the oil fumes enter the fan 13 through the oil fume outlet 1202. Since the air-collecting shell 1311 of the fan casing is mainly filled with oil fumes, and the air conditioner 11 is not turned on at this time, the oil fumes can enter the first heat exchange chamber 1101 through the first air inlet 1301 on the fan casing, which will cause the oil fumes to spread. The oil fumes can enter the kitchen through the first return air inlet 1102.

[0094] Furthermore, when neither the range hood main unit 12 nor the air conditioning main unit 11 is working, the gas from the flue may flow in the direction of atmospheric pressure in the first chamber 1304 of the fan main unit 13. The first air inlet 1301 can be selectively opened or closed through the first valve to prevent reverse airflow from entering the air conditioning main unit 11. The second valve can be closed through the oil fume inlet 1201 to prevent reverse airflow from entering the range hood main unit 12.

[0095] According to one embodiment of the present invention, the kitchen air conditioning system 1 further includes a return air assembly 16, which is connected to a second return air vent 1105 and is disposed on the ceiling of the kitchen. Air in the kitchen flows to the second return air vent 1105 through the return air assembly 16.

[0096] According to one embodiment of the present invention, the kitchen air conditioning system 1 further includes a return air assembly 16, which is installed on the ceiling of the kitchen and connected to a second return air inlet 1105. The return air assembly 16 is adapted to introduce the airflow in the kitchen into the first heat exchange chamber 1101 to further cool the airflow in the kitchen, so that the gas after heat exchange in the second heat exchange chamber 1104 enters the kitchen, thereby further improving the environment inside the kitchen.

[0097] This application places the return air assembly 16 on the ceiling of the kitchen, thus concealing the air outlet of the air conditioning system within the kitchen ceiling and improving the aesthetics of the kitchen air conditioning system. In some embodiments, the return air assembly 16 may be placed on the upper side of the ceiling directly in front of the range hood main unit 12.

[0098] like Figure 21 As shown, according to an embodiment of the present invention, the return air assembly 16 includes a return air housing, which is provided with a return air outlet communicating with the second heat exchange chamber 1104 and a return air inlet open towards the kitchen. A return air cavity is formed inside the return air housing, which is respectively connected to the return air outlet and the return air inlet, wherein the return air outlet is connected to the second return air port 1105 through a pipeline.

[0099] According to one embodiment of the present invention, the return air assembly 16 may further include a lighting lamp 161, which may be disposed on the lower side of the return air housing for illuminating the user.

[0100] According to one embodiment of the present invention, a first oil filter element 103 is provided on the second housing 121. The first oil filter element 103 is located at the oil fume inlet 1201. The first oil filter element 103 can be constructed as an oil filter grille. A second oil filter element 104 is also provided in the oil fume channel 1211. The second oil filter element 104 is constructed as an oil removal filter screen arranged at intervals in the extending direction of the oil fume channel 1211.
