[0027] As Figures 1 to 4 shown, Figure 1 Fig. shows a schematic diagram of a range hood provided by the present invention under a second operating condition. Figure 2 Fig. shows a schematic diagram of a range hood provided by the present invention under a first or third operating condition. Figure 3 Fig. shows a schematic diagram of a range hood provided by the present invention under a second operating condition. Figure 4 Fig. shows a schematic diagram of a range hood provided by the present invention under a third operating condition.

[0028] The range hood according to an embodiment of the present invention includes a range hood main body 1 and an air conditioner main body 2 integrated together. The range hood main body 1 includes a range hood internal flow channel 11 and a range hood fan 12 disposed in the range hood internal flow channel 11, and the range hood fan 12 is configured as a power source of the range hood main body 1; the air conditioner main body 2 includes an air conditioner internal flow channel 21 and an air conditioner fan 22 and two heat exchangers disposed in the air conditioner internal flow channel 21, and the air conditioner fan 22 provides a power source for one heat exchanger; wherein, the range hood internal flow channel 11 is isolated or communicated with the air conditioner internal flow channel 21, and the range hood fan 12 can also be configured as a power source of the other heat exchanger to adapt to the first to third operating conditions of the range hood.

[0029] As Figures 1 to 4As shown, the air conditioner main body 2 is integrated into the range hood main body 1 and is of an integrated structure, which facilitates the installation of the range hood main body 1 on the wall and also fixes the air conditioner main body 2 to the wall. Two heat exchangers are arranged inside the air conditioner main body 2, integrating the existing air conditioner outdoor unit into the air conditioner indoor unit. The circulation of the air conditioner outdoor unit is an external circulation, and the circulation of the air conditioner indoor unit is an internal circulation, so that the internal flow channel 21 of the air conditioner has both an internal circulation flow channel 211 and an external circulation flow channel 212. When air enters the internal circulation flow channel 211 to generate cold air, the external circulation flow channel 212 generates hot air, or when air enters the internal circulation flow channel 211 to generate hot air, the external circulation flow channel 212 generates cold air. A range hood fan 12 is arranged inside the range hood main body 1. After the internal flow channel 11 of the range hood is communicated with the internal flow channel 21 of the air conditioner, the range hood fan 12 can be used to provide a power source for the internal flow channel 11 of the range hood, and also provide a power source for the external circulation flow channel 212 of the internal flow channel 21 of the air conditioner, and suck the hot air or cold air generated by the external circulation flow channel 212 out of the range hood main body 1 through the range hood fan 12.

[0030] In the first working condition, there is no oil fume. When the air conditioner main body 2 is used alone, the air conditioner fan 22 and the range hood fan 12 are started at the same time. The air conditioner fan 22 provides a power source for the internal circulation flow channel 211 of the internal flow channel 21 of the air conditioner, and the range hood fan 12 provides a power source for the external circulation flow channel 212 of the internal flow channel 21 of the air conditioner. In the second working condition, there is oil fume. When the range hood main body 1 is used alone, only the range hood fan 12 is started, and the range hood fan 12 provides a power source for the internal flow channel 11 of the range hood. In the third working condition, there is oil fume. When the air conditioner main body 2 and the range hood main body 1 are used at the same time, the air conditioner fan 22 provides a power source for the internal circulation flow channel 211 of the internal flow channel 21 of the air conditioner, and the range hood fan 12 provides a power source for the internal flow channel 11 of the range hood and the external circulation flow channel 212 of the internal flow channel 21 of the air conditioner at the same time.

[0031] In a preferred embodiment of the present invention, a connecting air valve 3 is provided at the connecting position of the internal flow channel 11 of the range hood and the internal flow channel 21 of the air conditioner, and the connecting air valve 3 is located in the suction area of the range hood main body 1. By closing or opening the connecting air valve 3, the isolation or connection of the internal flow channel 11 of the range hood and the internal flow channel 21 of the air conditioner can be realized. When the connecting air valve 3 is closed, the range hood fan 12 is configured as a power source of the range hood main body 1. When the connecting air valve 3 is opened, the range hood fan 12 is configured as a power source of another heat exchanger.

[0032] As Figures 1 to 4As shown, the external circulation flow path 212 of the internal flow path 11 of the range hood and the internal flow path 21 of the air conditioner are connected through a connecting pipeline. The connecting air valve 3 is rotatably connected to the connecting pipeline. The connecting pipeline is arranged in the suction area of the internal flow path 11 of the range hood, that is, the front end of the internal flow path 11 of the range hood, rather than the exhaust area corresponding to the rear end of the internal flow path 11 of the range hood, so as to ensure that the range hood fan 12 effectively sucks the air in the external circulation flow path 212. When the range hood is in the first working condition or the third working condition, the connecting air valve 3 is fully opened or opened at a certain angle, so that the internal flow path 21 of the air conditioner and the internal flow path 11 of the range hood are communicated. Through the power source provided by the range hood fan 12, the cold air or hot air generated in the external circulation flow path 212 of the internal flow path 21 of the air conditioner is discharged outdoors through the exhaust port 14. If the range hood is in the second working condition, the connecting air valve 3 is closed, so as to prevent the oil fume entering the internal flow path 11 of the range hood from entering the internal flow path 21 of the air conditioner and reduce the pollution inside the air conditioner main body 2.

[0033] In a preferred embodiment of the present invention, the connecting air valve 3 is in the connecting air valve closed position, the connecting air valve 3 is closed, and when the connecting air valve 3 is in the connecting air valve open position, the connecting air valve 3 is opened.

[0034] As Figures 1 to 4 shown, the connecting air valve 3 is rotatably connected to the connecting pipeline. The connecting pipeline is in the horizontal direction. When the connecting air valve 3 is in the connecting air valve closed position, it is in the vertical state, and the connecting air valve 3 is perpendicular to the axial direction of the connecting pipeline, so as to close the connection between the internal flow path 11 of the range hood and the internal flow path 21 of the air conditioner. When the connecting air valve 3 is in the connecting air valve open position and is in the horizontal state or forms an angle with the vertical direction, a gap is formed between the connecting air valve 3 and the connecting pipeline. Under the action of the power of the range hood fan 12, air can enter the internal flow path 11 of the range hood from the internal flow path 21 of the air conditioner.

[0035] In a preferred embodiment of the present invention, the internal flow path 21 of the air conditioner is configured as an internal circulation flow path 211 and an external circulation flow path 212 that are interconnected. An indoor air inlet 2111 is provided at the internal circulation flow path 211 or at the connection between the internal circulation flow path 211 and the external circulation flow path 212 or in the external circulation flow path 212. An indoor air outlet 2112 is provided at the internal circulation flow path 211. The two heat exchangers are the first heat exchanger 23 and the second heat exchanger 24. The air conditioner fan 22 and the first heat exchanger 23 are arranged in the internal circulation flow path 211 and are located between the indoor air inlet 2111 and the indoor air outlet 2112. The second heat exchanger 24 is arranged in the external circulation flow path 212. The external circulation flow path 212 is isolated or communicated with the internal flow path 11 of the range hood. A connecting air valve 3 is provided at the communication position, and the connecting air valve 3 is located at the suction area of the range hood main body 1. By closing or opening the connecting air valve 3, the isolation or connection between the internal flow path 11 of the range hood and the external circulation flow path 212 is realized.

[0036] Preferably, the indoor air inlet 2111 is arranged at the inner circulation channel 211, an outdoor air inlet 2121 is added at the outer circulation channel 212, and a channel air valve 25 is provided at the connection position of the inner circulation channel 211 and the outer circulation channel 212. By adjusting the position of the channel air valve 25, the isolation or connection between the inner circulation channel 211 and the outer circulation channel 212 can be achieved.

[0037] As Figure 3 and Figure 4 shown, when there is no oil fume in the first working condition and the air conditioner main body 2 is used alone, the channel air valve 25 is adjusted to isolate the inner circulation channel 211 and the outer circulation channel 212, and the connection air valve 3 connects the outer circulation channel 212 and the internal flow channel 11 of the range hood. Under the action of the air conditioner fan 22, air enters the inner circulation channel 211 from the indoor air inlet 2111, is heated or cooled by the first heat exchanger 23 and then enters the room from the indoor air outlet 2112. At the same time, under the action of the range hood fan 12, air enters the outer circulation channel 212 from the outdoor air inlet 2121, is heated or cooled by the second heat exchanger 24 and then is discharged from the exhaust port 14 of the range hood main body 1 to the common flue or the outside. Since the air in the room is circulated for heat exchange, the temperature adjustment process of the indoor gas can be accelerated, and the user experience can be improved. In the second working condition, when there is oil fume and the range hood main body 1 is used alone, the connection air valve 3 is closed, and the channel air valve 25 can be in any position. In the third working condition, when there is oil fume and the air conditioner main body 2 is started at the same time, the channel air valve 25 is adjusted to close the indoor air inlet 2111, and at the same time, the inner circulation channel 211 and the outer circulation channel 212 are connected. The connection air valve 3 connects the outer circulation channel 212 and the internal flow channel 11 of the range hood. Under the simultaneous action of the air conditioner fan 22 and the range hood fan 12, air is provided to the first heat exchanger 23 and the second heat exchanger 24 at the same time from the outdoor air inlet 2121 for heat exchange, so as to introduce outdoor fresh air into the air conditioner main body 2 and avoid the air with oil fume in the room from entering the air conditioner main body 2.

[0038] The two heat exchangers include a first heat exchanger 23 and a second heat exchanger 24. Among them, the first heat exchanger 23 is arranged in the inner circulation channel 211, and the second heat exchanger 24 is arranged in the outer circulation channel 212. The air conditioner fan 22 is preferably arranged below the first heat exchanger 23, that is, on the side close to the indoor air outlet 2112 in the inner circulation channel 211. Water vapor usually condenses on the surface of the first heat exchanger 23, so that the attachment of impurities and dust can be reduced, and further the probability of impurities and dust attaching to the air conditioner fan 22 can be reduced.

[0039] Preferably, the air conditioner main body 2 further includes a compressor, a four-way valve, and a throttling device. The first heat exchanger 23, the second heat exchanger 24, the compressor, the four-way valve, and the throttling device are connected through a refrigerant pipeline. When the air conditioner main body 2 heats up, the first heat exchanger 23 serves as a condenser, and the second heat exchanger 24 serves as an evaporator. The refrigerant is pressurized by the compressor to become a high-temperature and high-pressure gas, enters the first heat exchanger 23 to condense and liquefy and release heat to become a liquid, and at the same time heats the air entering the internal circulation channel 211 from the indoor air inlet 2111. This air is discharged from the indoor air outlet 2112, thereby achieving the purpose of raising the indoor temperature. The refrigerant is depressurized by the throttling device, enters the second heat exchanger 24 to evaporate and vaporize and absorb heat to become a gas, and at the same time absorbs the heat of the air entering the external circulation channel 212 from the indoor air inlet 2111. This air becomes colder and is discharged from the smoke exhaust port 14 under the suction of the range hood fan 12. The refrigerant that has become a gas enters the compressor again to start the next cycle. When the air conditioner main body 2 is switched to refrigeration through the four-way valve, the first heat exchanger 23 serves as an evaporator, and the second heat exchanger 24 serves as a condenser. The refrigerant sequentially passes through the compressor, the second heat exchanger 24, the throttling device, and the first heat exchanger 23, thereby achieving the purpose of lowering the indoor temperature.

[0040] In a preferred embodiment of the present invention, when the flow channel air valve 25 is in the flow channel air valve closed position, the internal circulation channel 211 is isolated from the external circulation channel 212 and the indoor air inlet 2111 is opened. When the flow channel air valve 25 is in the flow channel air valve open position, the internal circulation channel 211 is communicated with the external circulation channel 212 and the indoor air inlet 2111 is closed.

[0041] As Figure 3 and Figure 4 shown, the flow channel air valve 25 is rotatably connected to the top wall of the air conditioner main body 2. The top of the air conditioner main body 2 is in the horizontal direction. In the first working condition, the flow channel air valve 25 extends vertically downward from the top wall of the air conditioner main body 2, and can separate the internal circulation channel 211 and the external circulation channel 212 into two relatively closed cavities. The indoor air inlet 2111 and the indoor air outlet 2112 are used for the internal circulation channel 211, and the outdoor air inlet 2121 is used for the external circulation channel 212, so as to circulate and exchange heat for the indoor air, which can accelerate the temperature adjustment process of the indoor gas and improve the user experience. In the third working condition, the flow channel air valve 25 is in the horizontal direction to close the indoor air inlet 2111 and communicate the internal circulation channel 211 and the external circulation channel 212, so that outdoor air enters the internal circulation channel 211 and the external circulation channel 212 respectively from the outdoor air inlet 2121, avoiding the indoor air containing oil fume from entering the interior of the air conditioner main body 2.

[0042] In a preferred embodiment of the present invention, the indoor air inlet 2111 and the indoor air outlet 2112 are oppositely arranged.

[0043] As Figures 1 to 4As shown, the indoor air inlet 2111 and the indoor air outlet 2112 are oppositely arranged at both ends of the internal circulation channel 211. The air entering the indoor air inlet 2111 sequentially passes through the first heat exchanger 23 and the air conditioner fan 22. Powered by the air conditioner fan 22, after heat exchange by the first heat exchanger 23, it is discharged from the indoor air outlet 2112, thus realizing the circulating heat exchange of the indoor air by the air conditioner main body 2 and also simplifying the structure of the air conditioner main body 2.

[0044] In a preferred embodiment of the present invention, the indoor air inlet 2111 and the indoor air outlet 2112 are respectively arranged at the top and bottom of the internal circulation channel 211.

[0045] As Figures 1 to 4 shown, since the use of cooking appliances in the kitchen can increase the air temperature in the kitchen, the air conditioner main body 2 is usually used for refrigeration. The indoor air inlet 2111 is arranged at the top of the internal circulation channel 211, and the indoor air outlet 2112 is arranged at the bottom of the internal circulation channel 211. During refrigeration, hot air rises and cold air sinks. When the air conditioner main body 2 is started, the refrigeration efficiency can be improved.

[0046] In a preferred embodiment of the present invention, the outdoor air inlet 2121 is arranged at the top of the external circulation channel 212.

[0047] As Figure 3 and Figure 4 shown, the outdoor air inlet 2121 is arranged at the top of the external circulation channel 212. When the flow channel air valve 25 is opened to connect the internal circulation channel 211 and the external circulation channel 212, after the air enters from the outdoor air inlet 2121, it flows downward into the internal circulation channel 211 and the external circulation channel 212 respectively.

[0048] In a preferred embodiment of the present invention, corresponding filtering devices 26 are provided at the indoor air inlet 2111 and the outdoor air inlet 2121.

[0049] As Figures 1 to 4 shown, the filtering device 26 is one of an air filter element, photocatalyst, activated carbon or an electrostatic purification device, and is arranged at the outdoor air inlet 2121 or the indoor air inlet 2111, which can preliminarily purify the air entering the interior of the air conditioner main body 2 to reduce the dust or impurities entering the interior of the air conditioner main body 2.

[0050] In a preferred embodiment of the present invention, the range hood main body 1 includes a smoke inlet 13, a smoke outlet 14 and an oil net 15. The smoke inlet 13 and the smoke outlet 14 are respectively arranged at the bottom and top of the range hood main body 1, and the oil net 15 is arranged at the smoke inlet 13.

[0051] As Figures 1 to 4As shown in the figure, the smoke inlet 13 is arranged at the bottom of the internal flow channel 11 of the range hood, and the smoke exhaust port 14 is arranged at the top of the internal flow channel 11 of the range hood. The range hood fan 12 arranged in the internal flow channel 11 of the range hood provides power, so that the oil fume can be sucked into the internal flow channel 11 of the range hood and discharged from the smoke exhaust port 14. The oil mesh 15 is arranged at the smoke inlet 13, which can filter out part of the grease in the oil fume and prevent too much oil fume containing grease from entering the internal flow channel 11 of the range hood.

[0052] The range hood of the present invention is connected to the internal flow channel 21 of the air conditioner through the internal flow channel 11 of the range hood, so that the air conditioner main body 2 and the range hood main body 1 share the range hood fan 12 as a power source for exhaust; the air conditioner fan 22 provides a power source for the internal circulation flow channel 211 of the air conditioner, and the range hood fan 12 provides a power source for the external circulation flow channel 212 and the internal flow channel 11 of the range hood, which is suitable for three working conditions of whether the air conditioner main body 2 and the range hood main body 1 are used alone or in combination. When the connecting air valve 3 is closed, it can prevent the oil fume from flowing back into the interior of the air conditioner main body 2 when the range hood main body 1 is used alone; when the indoor air contains oil fume, the outdoor air inlet 2121 is selectively used to introduce fresh air, further avoiding the drawback that the escaped oil fume circulates into the interior of the air conditioner main body 2 through the indoor air inlet 2111.
