Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0075] The following is based on the attached Figure 24-31 A kitchen air conditioning system 1 according to the present invention is described.

[0076] The kitchen air conditioning system 1 according to the present invention includes an air conditioning host 11, which can be used to provide low-temperature air to exchange heat with the air in the kitchen. The kitchen air conditioning system 1 also includes a range hood host 12, the function of which is to extract oil smoke.

[0077] In one embodiment of the present invention, the range hood host 12 has a range hood host housing 121, and the range hood host housing 121 is provided with a fume channel 1211 for circulating oil fumes and a heat exchange duct 1212 for circulating low-temperature airflow. The heat exchange duct 1212 is connected to the air outlet of the air-conditioning host 11, so that the airflow of the air-conditioning host 11 can enter the range hood host 12 through the heat exchange duct 1212 and flow out from the housing of the range hood host 12, so that the range hood host 12 can blow low-temperature air directly toward the user, adjust the temperature in the kitchen space, and deliver the low-temperature airflow directly to the user's working area.

[0078] The smoke and oil channel 1211 has a smoke inlet 1211a and a smoke outlet 1211b provided on the range hood main body shell 121, and the heat exchange air duct 1212 has an air-conditioning outlet 1212a and an air-conditioning inlet 1212b provided on the range hood main body shell 121. The air-conditioning inlet 1212b is connected to the air-conditioning main body 11, and the air-conditioning outlet 1212a is provided on the range hood main body 12, so that the range hood main body 12 can discharge air, thereby improving the integration of the range hood main body 12.

[0079] According to one embodiment of the present invention, a condensation channel 1211c is further formed in the range hood main unit 12. The condensation channel 1211c is adapted to be connected to the air conditioner main unit 11. Low-temperature airflow also flows through the condensation channel 1211c. Heat is exchanged between the condensation channel 1211c and the oil and smoke channel 1211, thereby lowering the temperature of the inner wall of the oil and smoke channel 1211 and thereby lowering the temperature of the oil and smoke flowing in the oil and smoke channel 1211, thereby condensing the oil and smoke in the oil and smoke channel 1211. This improves the oil and smoke filtering effect of the range hood main unit 12 and enhances the oil and smoke absorption capability of the range hood main unit 12.

[0080] According to the kitchen air conditioning system 1 of the present invention, the kitchen air conditioning system 1 has an air conditioning main unit 11 and a range hood main unit 12. The range hood main unit 12 is provided with an air conditioning air outlet 1212a for discharging air, and is also provided with a condensation channel 1211c connected to the heat exchange air duct 1212. The condensation channel 1211c improves the filtering effect of the range hood main unit 12 by exchanging heat with the smoke and oil channel 1211. The range hood main unit 12 has a strong ability to absorb oil smoke and a good smoke and oil filtering effect.

[0081] According to one embodiment of the present invention, the heat exchange duct 1212 is connected between the air-conditioning host 11 and the condensation channel 1211c, so that the condensation channel 1211c is indirectly connected to the air-conditioning host 11 through the heat exchange duct 1212, and the air flow of the air-conditioning host 11 enters the heat exchange duct 1212 through the air-conditioning air inlet 1212b. An air-conditioning outlet 1212a is provided on the range hood housing 121, and the air-conditioning outlet 1212a can guide part of the low-temperature airflow out of the range hood housing 121, so that the low-temperature airflow is blown toward the user, thereby improving the temperature around the user and improving the comfort of the kitchen.

[0082] The condensation channel 1211c can be arranged downstream of the heat exchange duct 1212 and connected to the heat exchange duct 1212 to be indirectly connected to the air outlet of the air-conditioning main unit 11. The remaining low-temperature airflow flows into the condensation channel 1211c, and the inner wall of the condensation channel 1211c exchanges heat with the smoke oil in the smoke oil channel 1211 to reduce the temperature of the oil smoke in the smoke oil channel 1211, accelerate the condensation speed of the smoke oil, and condense the smoke oil quickly to improve the range hood effect of the range hood main unit 12. The condensation channel 1211c is connected to the heat exchange duct 1212, which improves the integration of the range hood main unit 12, can reduce the volume of the range hood main unit shell 121, and reduce the number of flue openings.

[0083] According to one embodiment of the present invention, a first on-off device 101 is provided between the heat exchange duct 1212 and the condensation channel 1211c. The first on-off device 101 is used to connect or disconnect the heat exchange duct 1212 and the condensation channel 1211c. The first on-off device 101 can be used to control whether the airflow is directed to the condensation channel 1211c. The user can choose to open or connect the heat exchange duct 1212 and the condensation channel 1211c according to needs. When the flow rate of the low-temperature airflow provided by the air conditioner main unit 11 is low or the user has a high requirement for the ambient temperature, the first on-off device 101 is controlled to close the heat exchange duct 1212 and the condensation channel 1211c to ensure that most of the low-temperature airflow flows through the heat exchange duct 1212 and out of the range hood main unit housing 121, so that most of the airflow generated by the air conditioner main unit 11 is used to improve the user's ambient temperature.

[0084] When the flow rate of the low-temperature airflow provided by the air-conditioning host 11 is large or the user's requirement for the ambient temperature is low, the first on-off device 101 is controlled to open the heat exchange duct 1212 and the condensation channel 1211c to reasonably distribute the low-temperature airflow. Part of it is used to reduce the temperature of the area around the user, and the other part is used to reduce the temperature of the smoke oil in the smoke oil channel 1211 and increase the condensation speed of the smoke oil in the smoke oil channel 1211.

[0085] like Figures 25-26As shown, according to one embodiment of the present invention, the first on-off device 101 includes a drive motor 1011 and a baffle 1012. The baffle 1012 is disposed at the condensing channel inlet 1211d between the heat exchange duct 1212 and the condensing channel 1211c and blocks the condensing channel inlet 1211d. It should be noted that the condensing channel inlet 1211d can connect the heat exchange duct 1212 and the condensing channel 1211c. The condensing channel inlet 1211d is located at the end of the heat exchange duct 1212 and can be at the same level as the air conditioning outlet 1212a. The low-temperature airflow can be diverted between the air conditioning outlet 1212a and the condensing channel inlet 1211d, so that it can be blown out of the air conditioning outlet 1212a or enter the condensing channel 1211c. The baffle 1012 is movably disposed at the condensing channel inlet 1211d to control the opening or closing of the condensing channel 1211c, and the baffle 1012 can be movable to adjust the opening of the condensing channel 1211c.

[0086] According to one embodiment of the present invention, the drive motor 1011 is configured to drive the baffle 1012 to rotate around the baffle axis to adjust the opening of the condensation channel inlet 1211d. The output shaft of the drive motor 1011 can be connected to the baffle 1012, and the baffle 1012 can rotate with the output shaft of the drive motor 1011.

[0087] like Figure 25 and Figure 30 As shown, according to one embodiment of the present invention, the condensation channel 1211c has a condensation channel inlet 1211d and a condensation channel outlet 1211e, the condensation channel inlet 1211d is connected to the heat exchange air duct 1212, the condensation channel inlet 1211d and the condensation channel outlet 1211e are staggered, and the condensation channel inlet 1211d and the condensation channel outlet 1211e are not directly opposite each other, so that the condensation channel 1211c extends in a circuitous manner between the condensation channel inlet 1211d and the condensation channel outlet 1211e.

[0088] Among them, the condensation channel 1211c can be constructed as a serpentine channel to increase the length of the condensation channel 1211c, increase the heat exchange time between the low-temperature airflow and the oil smoke in the smoke oil channel 1211, and at the same time enable the airflow in the condensation channel 1211c to fully contact and exchange heat with the smoke oil in the smoke oil channel 1211, and fully utilize the cooling capacity of the low-temperature airflow generated by the air-conditioning host 11.

[0089] The condensation channel 1211c can also be constructed to extend in a "Z" shape, a zigzag shape, or a spiral shape, so that the low-temperature air can fully meander in the condensation channel 1211c, thereby improving energy utilization.

[0090] According to one embodiment of the present invention, the condensation channel 1211c includes: a condensation channel inlet section 1211f, a condensation channel outlet section 1211g and a condensation channel middle section 1211h connected to the condensation channel inlet section 1211f and the condensation channel outlet section 1211g, the condensation channel inlet section 1211f is located on the first side of the smoke oil channel 1211, the condensation channel outlet section 1211g is located on the second side of the smoke oil channel 1211, and the condensation channel middle section 1211h is located on the third side of the smoke oil channel 1211, the first side and the second side of the smoke oil channel 1211 are opposite to each other and the third side is connected to the first side and the second side.

[0091] The first and second sides of the smoke oil channel 1211 may be located on either side of the width of the smoke oil channel 1211. The condensation channel inlet section 1211f is located on the first side of the width of the smoke oil channel 1211. The condensation channel inlet 1211d is located directly above the condensation channel inlet section 1211f. Low-temperature air can enter the condensation channel inlet section 1211f from top to bottom. The condensation channel outlet section 1211g is located on the second side of the width of the smoke oil channel 1211. The condensation channel outlet 1211e is located below the condensation channel outlet section 1211g. After completing heat exchange, the low-temperature air flows out of the outlet of the condensation channel 1211c. The middle section 1211h of the condensation channel can be located on the front side of the smoke oil channel 1211, and the condensation channel inlet section, the middle section 1211h of the condensation channel and the condensation channel outlet section 1211g form a channel structure surrounding the periphery of the smoke oil channel 1211, so as to fully exchange heat with the smoke oil channel 1211, and perform heat exchange on the left and right sides of the smoke oil channel 1211 and the front of the smoke oil channel 1211, thereby increasing the heat exchange area of ​​the smoke oil channel 1211.

[0092] like Figure 30 As shown, according to one embodiment of the present invention, an air deflector assembly is disposed within at least one of the condensation channel inlet section 1211f, the condensation channel outlet section 1211g, and the condensation channel middle section 1211h. The air deflector assembly is configured to block airflow and guide airflow within the condensation channel 1211c so that the airflow extends in a circuitous manner within the condensation channel 1211c. The air deflector assembly may be spaced apart from at least one of the upper sidewall or the lower sidewall of the condensation channel 1211c to form a gap suitable for airflow, allowing the airflow to change its direction after passing through the gap, thereby achieving a circuitous flow within the condensation channel 1211c.

[0093] According to one embodiment of the present invention, the air guide plate assembly is arranged in the middle section 1211h of the condensation channel. Since the width of the middle section 1211h of the condensation channel is wider and the contact area between the smoke oil channel 1211 is larger, more heat can be exchanged with the smoke oil channel 1211. Providing the air guide plate assembly in the middle section can increase the contact area between the middle section 1211h of the condensation channel and the smoke oil channel 1211.

[0094] The air guide plate assembly includes at least one first air guide plate 1211i and at least one second air guide plate 1211j. The first air guide plate 1211i and the second air guide plate 1211j are arranged alternately. The upper end of the first air guide plate 1211i is connected to the upper end of the middle section 1211h of the condensation channel, and the lower end of the first air guide plate 1211i is spaced apart from the lower end of the middle section 1211h of the condensation channel. A gap is formed between the lower end of the first air guide plate 1211i and the lower side wall of the condensation channel 1211c. In order to change the flow direction of the airflow, the upper end of the second air guide plate 1211j is separated from the upper end of the middle section 1211h of the condensation channel, and the lower end of the second air guide plate 1211j is connected to the lower end of the middle section 1211h of the condensation channel. A gap is formed between the lower end of the second air guide plate 1211j and the upper side wall of the condensation channel 1211c to further change the flow direction of the airflow, so that the airflow flows back and forth in a serpentine shape, thereby extending the flow distance of the airflow and improving the heat exchange effect of the condensation channel 1211c.

[0095] According to one embodiment of the present invention, the smoke oil channel 1211 has a protrusion 102 that protrudes into the interior of the smoke oil channel 1211. The protrusion 102 can be configured as a protruding structure on the peripheral wall of the smoke oil channel 1211. The protruding structure can be stamped integrally with the peripheral wall of the smoke oil channel 1211. The protruding structure can increase the contact area between the smoke oil in the smoke oil channel 1211 and the peripheral wall of the smoke oil channel 1211. After the condensation channel 1211c exchanges the temperature of the smoke oil channel 1211, the peripheral wall of the smoke oil channel 1211 can more fully condense the oil smoke.

[0096] According to one embodiment of the present invention, the protrusions 102 are constructed in plurality and are arranged at intervals in the extension direction of the smoke oil channel 1211. The protrusions 102 can also be used to slow down the flow of oil smoke, so that the oil smoke is fully in contact with the surface of the smoke oil channel 1211, thereby extending the contact time between the oil smoke and the peripheral wall of the smoke oil channel 1211, so as to achieve a better effect of condensing the oil smoke.

[0097] According to one embodiment of the present invention, the protrusion 102 extends perpendicularly to the direction of flow of the smoke oil, and the protrusion 102 extends toward the inside of the smoke oil channel 1211 to hinder the flow of smoke. The protrusion 102 can be constructed in an arc shape, which will not excessively affect the flow of airflow while increasing the contact area, ensuring smooth circulation of the airflow and avoiding affecting the oil smoke suction at the smoking port of the range hood main unit 12.

[0098] According to one embodiment of the present invention, the condensation channel 1211c is defined by the outer wall of the condensation channel 1211c and the inner wall of the condensation channel 1211c. The outer wall of the condensation channel 1211c has a thermal insulation structure. The outer wall of the condensation channel 1211c can be constructed as a partial shell of the range hood main body shell 121. Providing a thermal insulation structure on the outer wall of the condensation channel 1211c can prevent the low-temperature gas from dissipating heat to the outside air through the range hood main body shell 121, so that most of the low-temperature air in the condensation channel 1211c is used to exchange heat with the oil smoke in the oil smoke channel, thereby reducing the waste of cold energy.

[0099] According to one embodiment of the present invention, the inner wall of the condensation channel 1211c is shared by the condensation channel 1211c and the smoke oil channel 1211, and a smoke oil channel 1211 shell can be provided in the range hood main body shell 121, and the range hood main body shell 121 can be sleeved on the outer periphery of the smoke oil channel 1211 shell, and a condensation channel 1211c is formed between the range hood main body shell 121 and the smoke oil channel 1211 shell, the inner surface of the smoke oil channel 1211 shell is the smoke oil channel 1211, and the outer surface of the smoke oil channel 1211 shell is the condensation channel 1211c, and the smoke oil channel 1211 shell is a shared shell of the condensation channel 1211c and the smoke oil channel 1211.

[0100] According to one embodiment of the present invention, no insulation material is provided on the housing of the smoke oil channel 1211 to improve the heat transfer efficiency between the condensation channel 1211c and the smoke oil channel 1211, thereby enhancing the heat exchange effect of the smoke oil channel 1211.

[0101] According to one embodiment of the present invention, condensation duct 1211c has a condensation duct inlet 1211d and a condensation duct outlet 1211e. Condensation duct outlet 1211e is provided with a pressure-controlled switch door 103. When the pressure of the low-temperature air in condensation duct 1211c reaches a preset value, the low-temperature air pushes open pressure-controlled switch door 103 to prevent the airflow in condensation duct 1211c from affecting the flow in heat exchange duct 1212. When the pressure switch door is closed, the low-temperature air in condensation duct 1211c fully exchanges heat with the smoke oil, extending the heat exchange time between the low-temperature air and the smoke oil and reducing cooling loss caused by the outflow of the low-temperature air.

[0102] like Figure 28As shown, according to one embodiment of the present invention, the pressure-controlled switch door 103 includes a door panel 1031 and an elastic structure 1032. The door panel 1031 can be rotatably arranged at the condensation channel outlet 1211e. The door panel 1031 has a door panel shaft, which is rotatably connected to the inner wall of the condensation channel 1211c; the elastic structure 1032 is sleeved on the door panel shaft. The elastic structure 1032 can be constructed as a spring. The first end of the elastic structure 1032 elastically presses against the inner wall surface of the range hood main body housing 121, and the second end of the elastic structure 1032 elastically presses against the inner wall surface of the door panel 1031. After the pressure in the condensation channel 1211c reaches the preset pressure, the door panel 1031 can be pushed open when the pressure exerted by the airflow on the door panel 1031 is greater than the elastic force of the spring to allow the airflow to circulate. After the airflow circulates, the airflow pressure in the condensation channel 1211c is lost, and the pressure switch door is further closed to avoid further loss of airflow in the condensation channel 1211c, so that the gas in the condensation channel 1211c can fully exchange heat with the oil smoke in the smoke and oil channel 1211, thereby improving the utilization efficiency of the low-temperature airflow and reducing the loss of cooling capacity.

[0103] Reference below Figure 1-Figure 23 A kitchen air conditioning system 1 according to an embodiment of the present invention is described.

[0104] like Figure 1-3 As shown, the kitchen air conditioning system 1 according to the present invention includes an air conditioner main unit 11, a range hood main unit 12, and an exhaust fan 13. The air conditioning system according to the present invention can be used independently in the kitchen. The air conditioner main unit 11 has cooling and / or heating functions and can be used to change the ambient temperature in the kitchen. The range hood main unit 12 is used to extract cooking fumes in the kitchen, and the exhaust fan 13 guides the fumes sucked by the range hood to provide negative pressure for the fumes to be extracted by the range hood.

[0105] In the related art, the air conditioner in the kitchen has low integration and a large number of components. The air flow needs to be guided in both the range hood and the air conditioner, but they cannot share the same fan. At the same time, the air outlet position of the air conditioner is greatly limited, and the air outlet position is far away from the user's position when cooking, and the ambient temperature of the user when cooking in the kitchen cannot be guaranteed.

[0106] like Figure 4-6As shown, in the kitchen air-conditioning system 1 according to the present invention, the air-conditioning host 11 includes an air-conditioning host housing 111, a first heat exchanger 112 and a second heat exchanger 113. The air-conditioning host housing 111 defines a first heat exchange chamber 1111 and a second heat exchange chamber 1112. The first heat exchanger 112 is arranged in the first heat exchange chamber 1111 and is suitable for exchanging heat with the air flow flowing through the first heat exchange chamber 1111. The second heat exchanger 113 is arranged in the second heat exchange chamber 1112 and is suitable for exchanging heat with the air flow flowing through the second heat exchange chamber 1112. The first heat exchanger 112 and the second heat exchanger 113 can be connected by a refrigerant pipeline. A compressor 114 and an expansion valve and other components are provided on the refrigerant pipeline so that the first heat exchanger 112 and the second heat exchanger 113 can complete the Carnot cycle.

[0107] Furthermore, a condensed water outlet 110 is provided on the air conditioner main body housing 111 for discharging condensed water.

[0108] Furthermore, a plurality of supporting legs 115 are provided on the bottom wall of the air conditioner main body housing 111 , and the supporting legs 115 are used to connect to the ceiling to fix the air conditioner main body housing 111 on the ceiling.

[0109] In addition, the first heat exchange chamber 1111 has a first return air port 1111a and a first air outlet 1111b, and the second heat exchange chamber 1112 has a second return air port 1112a and a second air outlet 1112b. The first return air port 1111a and the second return air port 1112a can be connected to the outside world respectively to provide air flow for heat exchange for the air conditioning host 11.

[0110] The air-conditioning main unit housing 111 of the air-conditioning main unit 11 integrates the first heat exchanger 112 and the second heat exchanger 113 into one, thereby improving the integration of the air-conditioning main unit 11. There is no need to set up an air-conditioning outdoor unit, reducing the number of components of the kitchen air-conditioning system 1, and making the installation of the kitchen air-conditioning system 1 simpler and more convenient.

[0111] like Figure 18-23 As shown, the range hood main unit 12 includes a range hood main unit housing 121 and an oil filter 122. A smoke oil channel 1211 is provided in the range hood main unit housing 121. The oil filter 122 can be arranged at the oil fume inlet 1211a of the smoke oil channel 1211. The smoke oil channel 1211 has an oil fume inlet 1211a and a flue outlet 1211b, wherein the oil fume inlet 1211a and the flue outlet 1211b are both formed on the range hood main unit housing 121. The oil filter 122 can filter the oil fume in the smoke oil channel 1211, thereby realizing the basic smoke and oil filtering function of the range hood main unit 12.

[0112] In addition, a heat exchange duct 1212 is also provided on the range hood main body shell 121 of the range hood main body 12, and the heat exchange duct 1212 has an air-conditioning outlet 1212a and an air-conditioning inlet 1212b. The air-conditioning outlet 1212a and the air-conditioning inlet 1212b are both provided on the range hood main body shell 121, and the air-conditioning inlet 1212b is connected to the first air outlet 1111b through an air outlet duct.

[0113] The low-temperature or high-temperature airflow generated by the air-conditioning host 11 can be transmitted to the heat exchange duct 1212 in the range hood host 12 through the air outlet duct, and blown from the range hood host 12 to the user through the air-conditioning outlet 1212a of the heat exchange duct 1212, effectively improving the ambient temperature of the user during the cooking process and improving the user's cooking comfort.

[0114] By setting a heat exchange air duct 1212 on the range hood housing 121 of the range hood main unit 12, the air flow generated by the air conditioning main unit 11 can be blown toward the user through the range hood main unit 12. At the same time, the air outlet position is located in the user's cooking area, which can be more adapted to the user's working position, making the layout of the kitchen air conditioning system 1 more indirect.

[0115] like Figure 12-17 As shown, according to one embodiment of the present invention, the kitchen air conditioning system 1 further includes an exhaust fan 13, which is connected to the second air outlet 1112b and the flue outlet 1211b, respectively, to discharge air from the second heat exchange chamber 1112 and the smoke and oil passage 1211. The exhaust fan 13 can be used to drive airflow and can simultaneously exhaust the gas after heat exchange in the second heat exchange chamber 1112 and exhaust the oil smoke passing through the smoke and oil passage 1211.

[0116] The exhaust fan 13 can act on the range hood main unit 12 and the air conditioning main unit 11 at the same time, providing power for the smoke oil channel 1211 and the air flow in the second heat exchange chamber 1112 respectively. The exhaust fan 13 can selectively serve the range hood main unit 12 or the air conditioning main unit 11, so that the number of components of the kitchen air conditioning system 1 is further reduced, and the degree of integration of the kitchen air conditioning system 1 is improved.

[0117] According to the kitchen air conditioning system 1 of the present invention, the kitchen air conditioning system 1 is provided with an air conditioning main unit 11 and a range hood main unit 12. A heat exchange air duct 1212 is provided on the range hood main unit 12. The heat exchange air duct 1212 is connected to the air conditioning outlet 1212a of the air conditioning main unit 11. The range hood main unit 12 can guide the airflow after heat exchange to the kitchen. The range hood main unit 12 integrates the dual functions of sucking 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 1 has a high degree of integration, a small number of components, and a simple and convenient layout.

[0118] In some embodiments of the present invention, the heat exchange duct 1212 and the smoke oil channel 1211 are arranged in parallel. The heat exchange duct 1212 can be used to circulate the low-temperature airflow generated by the air-conditioning host 11, thereby reducing the temperature of the pipe wall of the heat exchange duct 1212. The smoke oil channel 1211 adjacent to the heat exchange duct 1212 can perform heat exchange on the pipe wall of the heat exchange duct 1212 to reduce the temperature of the pipe wall of the smoke oil channel 1211, thereby making the smoke oil circulating in the smoke oil channel 1211 easier to condense, thereby improving the filtering effect of the range hood host 12 on oil smoke.

[0119] In some embodiments of the present invention, the heat exchange duct 1212 and the smoke oil channel 1211 can share the same tube wall, and adjacent heat exchange duct 1212 and smoke oil channel 1211 can be provided on the main housing of the range hood, and the tube wall of the heat exchange duct 1212 and the tube wall of the smoke oil channel 1211 have the same shell structure, thereby improving the heat exchange effect of the heat exchange duct 1212 on the smoke oil channel 1211, and enhancing the condensation effect of the smoke oil channel 1211 on the oil smoke.

[0120] According to one embodiment of the present invention, the air conditioner main unit 11 is arranged above the kitchen ceiling. Placing the air conditioner main unit 11 above the kitchen ceiling can conceal the air conditioner main unit 11 and facilitate the arrangement of the air outlet duct and the return air of the air conditioner main unit 11. Placing the air conditioner main unit 11 on the ceiling can also improve the aesthetics of the kitchen.

[0121] like Figure 7-11 As shown, according to one embodiment of the present invention, the kitchen air conditioning system 1 further includes a return air assembly 14, which is installed on the kitchen ceiling. The air in the kitchen flows to the first return air vent 1111a and the second return air vent 1112a through the return air assembly 14. The return air assembly 14 can direct the airflow inside the kitchen into the ceiling. The return air assembly 14 connects the lower part of the ceiling with the upper part of the ceiling. The airflow in the lower part of the ceiling enters the upper part of the ceiling through the return air assembly 14, while the first return air vent 1111a and the second return air vent 1112a are open above the ceiling. The airflow in the upper part of the ceiling can respectively enter the first return air vent 1111a and the second return air vent 1112a to exchange heat with the corresponding heat exchanger to achieve the cooling or heating function of the air conditioning main unit 11. By arranging the return air assembly 14 on the ceiling, the return air layout of the air conditioning main unit 11 is simplified.

[0122] According to one embodiment of the present invention, the return air assembly 14 includes a face frame 141 and a panel grille 142. The face frame 141 is adapted to be fixed to the kitchen ceiling, and the panel grille 142 is detachably mounted on the face frame 141. Return air assembly mounting holes may be provided on the ceiling, and the face frame 141 may be fixed to the return air assembly mounting holes. The face frame 141 serves as the mounting base for the panel grille 142, and the panel grille 142 is detachably mounted on the face frame 141 to facilitate subsequent cleaning and maintenance of the panel grille 142.

[0123] like Figure 10 and Figure 11 As shown, in one embodiment of the present invention, the face frame 141 includes an outer frame portion 1411 having a ring-shaped configuration. A connecting frame 1412 is disposed between opposing sides of the outer frame portion 1411. Connecting frames 1412 are provided with engaging holes 1413 extending through the thickness of the outer frame 1411. The panel grille 142 includes a grille body, on which a hook portion 1421 is rotatably disposed. At least a portion of the hook portion 1421 can pass through the engaging hole 1413 and engage with the engaging hole 1413 to connect the panel grille 142 to the face frame 141. To remove the panel grille 142 from the face frame 141, the hook portion 1421 can be rotated to separate the panel grille 142 from the face frame 141, making removal of the panel grille 142 from the face frame 141 easy.

[0124] In a specific embodiment of the present invention, two spaced-apart and parallel connecting skeletons 1412 are provided on the face frame 141, and each connecting skeleton 1412 is correspondingly provided with a snap-in hole 1413. Two hook portions 1421 are provided on the panel grille 142, and each hook portion 1421 is arranged opposite to the corresponding snap-in hole 1413. The two hook portions 1421 rotate in opposite directions to facilitate the user to remove the panel grille 142 from the face frame 141 from the bottom side.

[0125] According to one embodiment of the present invention, multiple air outlets 1212a are provided, spaced apart on the range hood housing 121. Multiple air outlets can be provided on the range hood housing 121. Distributing multiple second air outlets 1112b spaced apart on the range hood housing 121 can increase the airflow range and expand the area available for improving temperature. Users can selectively activate different air outlets 1212a to meet their individual needs.

[0126] For example, if the user feels that the surrounding temperature is too high, they can open multiple air-conditioning outlets 1212a to increase the air volume and quickly reduce the surrounding temperature. The user can select air-conditioning outlets 1212a at different heights according to their height. The user can also select the corresponding air-conditioning outlet 1212a according to the location of the cooking stove to reduce the feeling of being scorched.

[0127] According to one embodiment of the present invention, a plurality of air conditioning vents 1212a are respectively distributed on the front panel, left panel, and right panel of the range hood housing 121. The air conditioning vents 1212a provided on the front panel of the range hood housing 121 can be directly opposite the user's work area, thereby improving the temperature in the area directly facing the user. The air conditioning vents 1212a located on the left and right panels of the second interface 132 are selectively openable and closable. The air conditioning vents 1212a located on the left and right panels can be used to increase the range and volume of air outlet, thereby increasing the air outlet area and applicability of the kitchen air conditioning system 1.

[0128] According to one embodiment of the present invention, the air conditioning outlet 1212a located on the front is located above the oil fume inlet 1211a. Since the oil fume inlet 1211a can draw in the oil fume located below the oil fume inlet 1211a, if the air conditioning outlet 1212a is located below the oil fume inlet 1211a, the air flow blown out through the air conditioning outlet will be drawn away by the oil fume inlet 1211a, thus failing to achieve a cooling effect. By arranging the air conditioning outlet 1212a above the oil fume inlet 1211a, the air conditioning outlet 1212a is not interfered with by the oil fume inlet 1211a, ensuring that the air discharged from the air conditioning outlet 1212a can be delivered to the user's surroundings, thereby improving the working environment around the user.

[0129] In a specific embodiment of the present invention, the air conditioning outlet 1212a located on the front panel of the air conditioning main body housing 111 can be configured as an elongated strip-shaped outlet. This outlet can extend in the width direction of the range hood main body housing 121 to increase the air outlet width and improve the area covered by the air conditioning outlet 1212a. The air conditioning outlet 1212a located on the front panel of the air conditioning main body housing 111 can be configured as a rectangular hole extending in the transverse direction of the front panel of the air conditioning main body housing 111. The airflow after passing through the first heat exchange chamber 1111 is directed through the air conditioning outlet 1212a to the front area directly opposite the range hood main body 12, exchanging heat in this area, thereby improving the ambient temperature in the front area.

[0130] The air-conditioning outlets 1212a located on the left and right panels of the range hood main body shell 121 can also be constructed as rectangular air outlets. The two air-conditioning outlets 1212a located on the left and right panels of the range hood main body shell 121 extend in the height direction of the range hood main body shell 121 and are open to both sides, which can further expand the air outlet range covered by the air-conditioning outlets 1212a located on the range hood main body 12, and the air-conditioning outlets 1212a located on the left and right panels can be optionally closed.

[0131] Multiple stoves can be set directly below the range hood main unit 12, and the air-conditioning outlets 1212a 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 1212a on the left panel are opened to improve the ambient temperature of the corresponding area.

[0132] In one embodiment of the present invention, each air-conditioning outlet 1212a is provided with an air guide plate for adjusting the air outlet direction. The air guide plates may include a first air guide plate 12121, a second air guide plate 12122, and a third air guide plate 12123. The first air guide plate 12121 includes a pivot portion 12121a adapted to be connected to a driving member 1212d, the output end of the driving member 1212d adapted to drive the pivot portion 12121a to rotate. It should be noted that when the driving member 1212d drives the pivot portion 12121a to rotate, the rotation axis of the output shaft of the driving member 1212d is aligned with the extension direction of the air-conditioning outlet 1212a located on the front panel of the range hood housing 121. An air guide portion 12121b is provided on the side of the pivot portion 12121a facing away from the air conditioning outlet 1212a. This air guide portion 12121b is constructed in an arc shape that bulges away from the air conditioning outlet 1212a, giving the range hood 12 a more rounded and aesthetically pleasing appearance. When the driver 1212d rotates the first air guide plate 12121, at least a portion of the first air guide plate 12121 rotates to be accommodated within the air conditioning outlet 1212a on the front of the range hood housing 121. This opens the air conditioning outlet 1212a on the front of the range hood housing 121, while concealing the first air guide plate 12121.

[0133] Furthermore, since the outer side of the air guide portion 12121b of the first air guide plate 12121 is constructed as an arc protruding from the front panel of the range hood main body shell 121, the driving member 1212d adjusts the air outlet area of ​​the air-conditioning outlet 1212a located on the front of the range hood main body shell 121 by changing the pivot angle of the first air guide plate 12121, and the user can adjust the rotation angle of the first air guide plate 12121.

[0134] Air-conditioning outlets 1212a are provided on the left and right panels of the air-conditioning main body housing 111, and a driving member 1212d for driving the second air guide plate 12122 and the third air guide plate 12123 can be provided in the air-conditioning outlet 1212a. The second air guide plate 12122 and the third air guide plate 12123 can both be constructed as rectangular plates. The driving member 1212d is constructed as a driving motor and is arranged on the lower side of the corresponding air-conditioning outlet 1212a. The output shaft of the driving motor can be connected to the corresponding second air guide plate 12122 and the third air guide plate 12123. The output shaft of the driving motor is the same as the extension direction of the corresponding second air guide plate 12122 and the third air guide plate 12123, so as to drive the second air guide plate 12122 and the third air guide plate 12123 to open in a direction away from each other, thereby increasing the air outlet width of the range hood main body 12.

[0135] Similarly, the rotation angles of the second air guide plate 12122 and the third air guide plate 12123 can be selectively adjusted. By controlling the driving motors of the second air guide plate 12122 and the third air guide plate 12123, the width of the air outlet range of the range hood main unit 12 can be adaptively adjusted, and can be adjusted according to the user's choice.

[0136] like Figure 18 As shown, according to one embodiment of the present invention, the kitchen air conditioning system 1 further includes a switch panel assembly 15 for adjusting the size of the oil fume inlet 1211a. The switch panel assembly 15 is movably mounted on the range hood housing 121. The switch panel assembly 15 can be mounted on the front of the range hood housing 121. The front of the range hood housing 121 is provided with an oil fume inlet 1211a, which is located on the lower side of the front panel of the range hood housing 121. The oil fume inlet 1211a can include a plurality of elongated holes extending through the front panel of the range hood housing 121. Each elongated hole extends in the height direction and is spaced apart in the width direction of the front panel of the range hood housing 121. At least some of the elongated holes extend to the lower end surface of the range hood housing 121.

[0137] In one embodiment of the present invention, the switch panel assembly 15 is rotatably mounted on the range hood housing 121. The switch panel assembly 15 has an open and closed state. When closed, the switch panel assembly 15 covers the front of the range hood housing 121, thereby covering the oil fume inlet 1211a on the front of the range hood housing 121, leaving only the oil fume inlet 1211a located at the lower end of the range hood housing 121. The closed state of the switch panel assembly 15 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 12.

[0138] When the panel assembly switches from a closed state to an open state, the upper end of the panel assembly is pivotally connected to the front panel of the range hood housing 121, and the panel assembly can also be driven by a drive motor, the output shaft of the drive motor being oriented in the width direction of the front panel of the second interface 132. During the rotation of the range hood housing 121, the inner side of the panel assembly can be pivoted away from the front panel of the range hood housing 121, thereby making the panel assembly perpendicular to the front panel of the range hood housing 121, so that a certain angle is formed between the panel assembly and the front panel of the range hood housing 121, thereby opening the oil fume inlet 1211a on the front panel of the range hood housing 121 and increasing the area of ​​the oil fume inlet 1211a. Since the panel assembly rotates away from the front panel of the range hood housing 121, the space occupied by the range hood 12 is increased, but the oil fume inlet 1211a on the front panel of the range hood housing 121 is opened at the same time, thereby improving the suction capacity of the range hood 12, making the range hood 12 suitable for extracting large oil fumes.

[0139] In one embodiment of the present invention, the panel assembly 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 panel assembly can also be turned on in a combination of the above two ways, with the user's manual setting taking priority over the automatic detection. This can further improve the automation level of the kitchen air conditioning system 1.

[0140] According to one embodiment of the present invention, an oil collecting box 151 is further provided on the lower side of the range hood main body shell 121, and the lower end of the range hood main body shell 121 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 1211a that is not covered by the panel assembly, and this part of the oil fume inlet 1211a 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 1211a on the inclined surface can increase the cross-sectional area of ​​this part of the oil fume inlet 1211a, so that it has sufficient ability to absorb oil fume when the panel assembly is not opened.

[0141] Furthermore, the lower end of the range hood housing 121 is constructed into a trapezoidal shape, which facilitates the flow of oil fumes through the oil fume inlet 1211a. Under the influence of gravity, the oil fumes flow toward the oil collection box 151 located on the bottom surface of the trapezoidal structure. The upper end of the oil collection box 151 also has an oil collection 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 1211a in the height direction. This ensures that the oil fumes filtered by the oil fume inlet 1211a located on the front side of the trapezoidal structure fall into the oil collection box 151, preventing oil fumes from dripping onto the countertop.

[0142] According to one embodiment of the present invention, the exhaust fan 13 is arranged on the outside of the air-conditioning main unit housing 111 and on the outside of the range hood main unit housing 121. By respectively arranging the exhaust fan 13 on the outside of the air-conditioning main unit housing 111 and the range hood main unit housing 121, the layout of the kitchen air-conditioning system 1 can be made more flexible, and the layout positions of the air-conditioning main unit 11 and the range hood main unit 12 will not be restricted. By arranging the exhaust fan 13 separately, it can be arranged in a layout method 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 1.

[0143] like Figure 12-17 As shown, the exhaust fan 13 has a first interface 131 connected to the second air outlet 1112b. The exhaust fan 13 may include a fan casing 13a. The fan casing 13a is internally provided with an accommodating space for accommodating a wind wheel. The wind wheel rotates in the fan casing 13a to generate negative pressure at the first interface 131. The first interface 131 is connected to the second air outlet 1112b. The second heat exchange chamber 1112 in the air-conditioning host 11 can exchange heat through the air flow in the second chamber, wherein the second heat exchanger 113 in the second heat exchange chamber 1112 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 1112, and the air flow with increased temperature can be discharged from the air-conditioning host 11 through the second air outlet 1112b. The first interface 131 of the exhaust fan 13 is connected to the second air outlet 1112b. Under the action of the rotation of the wind wheel, negative pressure is generated at the first interface 131 to discharge the air flow passing through the second heat exchange chamber 1112, and at the same time, the air intake efficiency of the second return air outlet 1112a can be improved.

[0144] In another embodiment of the present invention, a wind wheel can be separately disposed within the second heat exchange chamber 1112. The wind wheel can guide the airflow within the second heat exchange chamber 1112, which is equivalent to disposing a fan within the second heat exchange chamber 1112 to independently control the air intake and exhaust of the air conditioner 11. The wind wheel can also increase the return air volume of the second return air port 1112a and the outlet air volume of the second air outlet 1112b, thereby helping to improve the heat exchange efficiency of the air conditioner 11.

[0145] According to one embodiment of the present invention, the exhaust fan 13 has a second interface 132 connected to the flue outlet 1211b, and the wind wheel rotates in the fan casing 13a to generate negative pressure at the second interface 132. The second interface 132 is connected to the flue outlet 1211b. When the range hood main unit 12 performs oil fume removal work, the wind wheel rotates to drive the airflow and generate negative pressure at the second interface 132. The second interface 132 is connected to the oil fume outlet, so that the oil channel 1211 in the range hood main unit 12 also generates negative pressure, and enables the range hood main unit 12 to perform oil fume extraction work.

[0146] In another embodiment of the present invention, a wind wheel can be separately installed on the range hood main unit 12. The wind wheel can guide the oil smoke in the smoke and oil channel 1211. This is equivalent to installing a fan on the range hood main unit 12, which can be used to independently control the exhaust operation of the range hood main unit 12. The wind wheel installed on the range hood main unit 12 can also improve the suction force of the oil smoke inlet 1211a of the range hood main unit 12, so that the range hood main unit 12 can operate independently of the air conditioner main unit 11.

[0147] According to one embodiment of the present invention, a third interface 133 is provided on the fan casing 13a, and the third interface 133 is connected to the exhaust pipe. The third interface 133 can guide the airflow and / or oil smoke after heat exchange out of the fan casing 13a to be discharged to the exhaust pipe. It should be noted here that the third interface 133 is equivalent to the exhaust port of the fan casing, and the third interface 133 is connected to the exhaust pipe. The exhaust pipe can be the flue in the kitchen room, or a hose connecting the third interface 133 to the flue in the kitchen room. The third interface 133 can guide the air after heat exchange generated by the air-conditioning host 11 and the oil smoke sucked by the range hood host 12.

[0148] Among them, the range hood main unit 12 and the air conditioner main unit 11 can work independently or in coordination, and the gas exported by the third interface 133 can be the gas with a higher temperature after passing through the second heat exchange chamber 1112, or it can be the oil smoke sucked through the range hood main unit 12, or it can be a mixture of the above two gases.

[0149] According to one embodiment of the present invention, the second interface 132 is provided with a first valve 132a for opening or closing the second interface 132. The second interface 132 is used to connect the smoke and oil channel 1211 with the accommodating chamber in the fan casing 13a of the exhaust fan 13. The first valve 132a is provided at the second interface 132, which can be used to select to open or close the second interface 132. When the second interface 132 is closed, the range hood main unit 12 is in a closed state, and the smoke in the smoke and oil channel 1211 will not enter the accommodating chamber of the fan casing 13a. The purpose of the second valve 131a is to prevent the smoke in the smoke and oil channel 1211 from entering the fan casing 13a of the exhaust fan 13, so as to avoid the smoke from entering the air-conditioning main unit 11 through the first interface 131, thereby avoiding the occurrence of smoke cross-contamination.

[0150] In addition, after the air conditioner host 11 is turned on alone, in order to prevent part of the airflow from entering the smoke oil channel 1211 through the second interface 132, the second valve 131a can also ensure that the high-temperature airflow after heat exchange will not enter the room through the smoke oil channel 1211.

[0151] According to one embodiment of the present invention, the first interface 131 is provided with a second valve 131a for opening or closing the first interface 131. The first interface 131 is a communication interface connecting the second heat exchange chamber 1112 of the air conditioner main unit 11 and the accommodating chamber of the fan housing 13a of the exhaust fan 13. The second valve 131a is provided on the first interface 131 to control the opening and closing of the first interface 131. This prevents the airflow in the accommodating chamber of the fan housing 13a of the exhaust fan 13 from flowing back into the air conditioner main unit 11.

[0152] For example, when the range hood main unit 12 is used alone and the air conditioning main unit 11 is not turned on, the range hood main unit 12 draws in oil smoke through the smoke and oil channel 1211, and the oil smoke enters the accommodating cavity of the fan housing of the exhaust fan 13 through the second interface 132. Since the accommodating cavity of the fan housing mainly contains oil smoke, the air conditioning main unit 11 is not turned on at this time, and the oil smoke can enter the second heat exchange chamber 1112 through the first interface 131 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 1112a.

[0153] In addition, when the range hood main unit 12 and the air conditioner main unit 11 are not working, the gas from the exhaust pipe may flow in a certain direction under the action of atmospheric pressure, and a second valve 131a is set at the first interface 131. The first interface 131 can be selectively opened or closed through the second valve 131a to prevent reverse airflow from entering the air conditioner main unit 11.

[0154] By setting a second valve 131a at the first interface 131, the second valve 131a can be selectively opened or closed to control the first interface 131. When one of the air-conditioning host 11 or the range hood host 12 is working, the second valve 131a closes the first interface 131 to avoid the influence of the exhaust pipe and the range hood host 12 on the air-conditioning host 11.

[0155] According to one embodiment of the present invention, the exhaust fan 13 is disposed within the second heat exchange chamber 1112. This placement of the exhaust fan 13 within the second heat exchange chamber 1112 improves the integration of the kitchen air conditioning system 1, eliminating the need for a separate exhaust fan 13. Instead, a range hood interface is provided on the air conditioning unit housing 111. Smoke drawn by the range hood unit 12 can enter the second heat exchange chamber 1112 through the interface. The interface is connected to the flue outlet 1211b via a range hood duct, allowing the smoke and oil passage 1211 in the range hood unit 12 to directly communicate with the second heat exchange chamber 1112. This embodiment also achieves a layout in which the range hood unit 12 and the air conditioning unit 11 share the same exhaust fan 13, while also reducing the number of components in the kitchen air conditioning system 1. This makes the layout of the kitchen air conditioning system 1 more flexible and convenient.

[0156] According to one embodiment of the present invention, the kitchen air-conditioning system 1 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 smoke oil channel 1211 and the second heat exchange duct 1212. When the air-conditioning host 11 and the range hood host 12 work synchronously, the third valve is opened to allow the smoke sucked by the range hood host 12 to enter the second heat exchange chamber 1112 and be discharged synchronously with the air flow after heat exchange through the second heat exchanger 113 under the action of the exhaust fan 13. When the air-conditioning host 11 is turned on alone, the third valve can cut off the range hood interface so that the air flow generated by the exhaust fan 13 can act alone in the second heat exchange chamber 1112, thereby reducing flow loss.

[0157] The third valve can also be used to block the oil smoke in the oil smoke channel 1211 from entering the second heat exchange chamber 1112, thereby preventing the oil smoke remaining in the oil smoke channel 1211 from flowing when the air conditioner host 11 is not working, and preventing the oil smoke from entering the second heat exchange chamber 1112.

[0158] like Figure 23As shown, according to one embodiment of the present invention, the heat exchange air duct 1212 has a cold air outlet 1212c that supplies air toward the oil filter 122. A switch assembly 12124 is provided at the cold air outlet 1212c for opening or closing the outlet. By providing the cold air outlet 1212c and the switch assembly 12124, the cold air supplied from the heat exchange air duct 1212 is directed toward the oil filter 122 under the guidance of the switch assembly 12124, thereby condensing the oil stains on the oil filter 122 and rapidly condensing the hot oil smoke. When the range hood main unit 12 is performing a range hood extraction operation, the switch assembly 12124 is opened to direct the low-temperature airflow toward the oil filter 122, thereby lowering the temperature of the oil filter 122 and improving the oil filtering effect of the oil filter 122.

[0159] In a specific embodiment of the present invention, a rotatable switch panel assembly 15 is provided on the range hood main body housing 121. The switch panel assembly 15 is rotated to select whether to cover or open the oil fume inlet 1211a located on the front panel of the range hood main body housing 121, and an oil filter 122 is provided at the oil fume inlet 1211a. The oil filter can be constructed as a grille formed on the front panel of the range hood main body housing 121, and the oil filter grille is formed with a plurality of long strip holes, which are constructed as the oil fume inlet 1211a.

[0160] The switch panel assembly 15 can be rotatably arranged on the front panel of the range hood main body shell 121. When the switch panel assembly 15 is flipped in a direction away from the front panel of the range hood main body shell 121, the long hole can be exposed to improve the range hood main body 12's oil fume absorption effect. The cold air outlet can be arranged on the inner side or lower end of the switch panel assembly 15, and the cavity in the switch panel assembly 15 can be constructed as part of the heat exchange air duct 1212. The cold air outlet 1212c is arranged on the inner side of the switch panel assembly 15. It is arranged toward the front panel of the range hood main body shell 121, and the switch assembly 12124 can be opened and closed at the cold air outlet, and the switch assembly 12124 is opened after the switch panel assembly 15 is opened. After the switch assembly 12124 is opened, it can extend toward the front panel of the range hood main body shell 121, and can be extended toward the oil filter 122. The cold air blown out from the cold air outlet can be blown toward the oil filter 122 under the guidance of the switch assembly 12124 to improve the oil filtering effect of the oil filter 122.

[0161] According to one embodiment of the present invention, the switch assembly 12124 is configured to direct the heated air to the oil filter 122 when the cold air outlet is open. It should be noted that when the air conditioner main unit 11 is cooling, the gas discharged after passing through the first heat exchange chamber 1111 is low-temperature gas. After entering the heat exchange air duct 1212, the low-temperature gas is directed toward the oil filter 122 under the guidance of the switch assembly 12124. This utilizes the low-temperature gas generated by the air conditioner main unit 11 to accelerate the condensation of oil smoke and improve the oil filtering capacity of the range hood main unit 12.

[0162] In some embodiments of the present invention, the air-conditioning host 11 may also have a heating working condition. The gas discharged after passing through the first heat exchange chamber 1111 is high-temperature gas. After the high-temperature gas enters the heat exchange air duct 1212, it is blown toward the oil filter 122 under the guidance of the switch component 12124 to melt the oil stains on the oil filter 122 and facilitate the cleaning of the oil filter 122.

[0163] In one embodiment of the present invention, a switch assembly driving motor 12124a for driving the switch assembly 12124 to rotate is provided on the switch panel assembly 15, and the output shaft of the switch assembly driving motor 12124a is used to drive the switch assembly 12124 to rotate to control the opening and closing of the cold air outlet 1212c.
