Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] FIG. 1 is a view of a kitchen air-conditioning system in which a first air exhaust passage is open according to an embodiment of the present invention;

[0017] FIG. 2 is a view of the kitchen air-conditioning system in which the first air exhaust passage is closed according to the embodiment of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

[0018] The present invention will be further described below in detail with reference to the accompanying drawings by embodiments.

[0019] As shown in FIG. 1 and FIG. 2, it is a preferred embodiment of a kitchen air-conditioning system according to the present invention. The kitchen air-conditioning system comprises an air-conditioning assembly 1 and a range hood assembly 2.

[0020] The air-conditioning assembly 1 comprises a compressor 11, a first heat exchanger 12 and a second heat exchanger 13, the compressor 11 is connected with the first heat exchanger 12 and the second heat exchanger 13 through a plurality of refrigerating medium pipes 14. A throttle valve 18 is disposed in one of the refrigerating medium pipers 14 between the first heat exchanger 12 and the second heat exchanger 13, and a four-way valve (not shown) is disposed on one of the refrigerating medium pipes 14 between the compressor 11 and the first heat exchanger 12. By switching the four-way valve, the air-conditioning assembly 1 can be switched between cooling and heating modes. In the cooling mode, the first heat exchanger 12 is a condenser and the second heat exchanger 13 is an evaporator. In the heating mode, the first heat exchanger 12 is an evaporator and the second heat exchanger 13 is a condenser. The operating principle of the air-conditioning assembly 1 is the same as that of existing air-conditioners, which will not be described here.

[0021] The range hood assembly 2 comprising a fan 21 with a fan outlet 211 and an air exhaust passage connected to the fan outlet 211, the compressor 11 of the air-conditioning assembly 1 is attached to the range hood assembly 2, and the first heat exchanger 12 is disposed inside the air exhaust passage.

[0022] Specifically, the air exhaust passage is divided into a first air exhaust passage 22 and a second air exhaust passage 23 by a turnout 31, and a switching valve 3 is disposed at the turnout 31; the switching valve 3 connects the fan outlet to the first air exhaust passage 22 or to the second air exhaust passage 23.

[0023] In this embodiment, the first heat exchanger 12 is disposed inside the first air exhaust passage 22. To avoid fume from polluting the first heat exchanger 12, a fume purification device 4 is disposed inside the first air exhaust passage 22 and in front of the first heat exchanger 12, thereby prolonging the service life of the first heat exchanger 12 and improving the energy efficiency of the air-conditioner.

[0024] The air-conditioning assembly 1 comprises a fresh air inlet 15 and a fresh air outlet 16, and a plurality of fresh air purification devices 17 are disposed in air ducts of the fresh air inlet 15 and in the fresh air outlet 16. The fresh air inlet 15 is in communication with external environment, and the fresh air outlet 16 locates in front of the second heat exchanger 13 and communicates with interior space of the kitchen.

[0025] In this embodiment, the air-conditioning assembly 1 further comprises a motor 193, a first fan 191 and a second fan 192, the first fan 191 and the second fan 192 are coaxially mounted to the motor 193; the first fan 191 and the second fan 192 rotate together driven by the motor 193, and both are disposed at back of the second heat exchanger 13.

[0026] When the air conditioner is started up, the first air exhaust passage 22 is open and the second air exhaust passage 23 is closed by switching the switching valve 3. Taking the cooling mode of the air-conditioner as an example, the first heat exchanger 12 is the condenser and the second heat exchanger 13 is the evaporator, fresh air from the fresh air inlet 15 is cooled down and then blown out from the fresh air outlet 16 to supply cold air for the kitchen. Meanwhile, flue gas discharged from the fan 21 enters the first air exhaust passage 22 to dissipate heat of the condenser and is discharged from the first air exhaust passage 22 after taking away heat, thereby improving the heat exchange effect of the first heat exchanger 12 and further facilitating improving the energy efficiency of the air-conditioner.

[0027] When the air conditioner stops running, a range hood is in normal operation. At this moment, the first air exhaust passage 22 is closed and the second air exhaust passage 23 is open by switching the switching valve 3, and the flue gas discharged from the fan 21 enters the second air exhaust passage 23 and then is discharged.
