Detailed Description

The invention is described in further detail below with reference to the accompanying examples.

The first embodiment is as follows:

as shown in fig. 1 and fig. 2, the kitchen air conditioning system of the present embodiment includes an air conditioning assembly 1 and a range hood assembly 2. The air conditioning assembly 1 includes a compressor 11, a first heat exchange assembly 12 and a second heat exchange assembly 13, the compressor 11, the first heat exchange assembly 12 and the second heat exchange assembly 13 are communicated with each other through a refrigerant pipeline 14, a throttle valve 18 is installed on the refrigerant pipeline 14 between the first heat exchange assembly 12 and the second heat exchange assembly 13, and a four-way valve (not shown) is installed on the refrigerant pipeline 14. Through switching the four-way valve, can switch under refrigeration mode and heating mode, under refrigeration mode, first heat exchange assembly 12 is the condenser, and second heat exchange assembly 13 is the evaporimeter, and under the heating mode, first heat exchange assembly 12 is the evaporimeter, and second heat exchange assembly 13 is the condenser. The operation principle of the air conditioning assembly 1 is the same as that of the existing air conditioner and will not be described herein.

The oil smoke absorbing component 2 comprises a fan component 21, a smoke discharging channel 22 communicated with the air outlet of the fan, and an air inlet channel 23 communicated with the air inlet of the fan. The fan in the range hood has two functions: the range hood can be used as a fan of the range hood to achieve the effect of oil smoke exhaust, can provide air inlet amount for an air conditioning system, provides help for heat exchange of an air conditioning system, and achieves the effect of supplying cold or heat for a kitchen.

The first heat exchange assembly 12 is disposed within the flue gas channel. According to the arrangement, a smoke exhaust passage can be provided for the oil smoke exhaust system on the first aspect, the arrangement simplifies the installation problem of the first heat exchange assembly on the second aspect, the overall structure is compact, the outdoor unit provided with the heat exchange assembly is not required to be installed outside a user room, the structure is more beneficial to operation of workers, the installation process is safer and more reliable, and on the third aspect, the smoke exhaust passage is large in length and large in space, so that sufficient space is provided for heat exchange between smoke and the first heat exchange assembly, heat exchange is sufficient, heat generated by the air exchange assembly is exhausted through a flue, heat can be efficiently dissipated for the air exchange assembly, the refrigerating capacity of the air exchange assembly is improved by 10-15%, and a cool and comfortable kitchen environment is created.

The smoke exhaust channel forms a first smoke exhaust channel 221 and a second smoke exhaust channel 222 through a bifurcate opening, a switching valve 3 is arranged at the bifurcate opening, and the first smoke exhaust channel 221 is communicated with the air outlet of the fan or the second smoke exhaust channel 222 is communicated with the air outlet of the fan by switching the switching valve 3. When the air valve is arranged on the right side, the range hood works independently, and the air conditioning system is not started; the other is that the air valve is arranged on the left side, so that the effect of simultaneously working for oil smoke exhaust and air conditioning is achieved. Therefore, when heating or refrigeration is not needed, the heat exchange assembly can not be polluted by oil smoke, and the service life of the heat exchange assembly is prolonged.

The air conditioning component compressor is integrated on the oil fume exhaust system, the compressor is arranged in the shell of the range hood, the connection between the heat exchange component in the range hood and the heat exchange component in the inner machine is structurally easier to realize, a refrigerating or heating pipeline is formed, the device is more compact in structure, and the heat exchange component and the pipeline are convenient to install. The compressor is arranged in the oil fume exhaust system, the sealing effect is good, and the noise caused by vibration can be reduced.

In order to avoid the oil fume from polluting the first heat exchange assembly 12, the first fume exhaust channel 22 is internally provided with an oil fume purification device 4, the oil fume purification device 4 is arranged at the front end of the first heat exchange assembly 12, the fume exhaust system is internally provided with a purification device which can provide oil-grease separation degree of the oil fume, the oil fume is filtered and then passes through a heat exchange device, the working efficiency and the service life of the heat exchange device can be greatly improved, the oil fume content can be reduced by 80-90% after the gas exhausted by filtering, and the environment protection is facilitated.

When the air conditioner starts, through the switching of diverter valve 3, make first exhaust smoke passageway 22 open, second exhaust smoke passageway 23 closes, for example under the air conditioner refrigeration mode, first heat exchange assembly 12 is the condenser, second heat exchange assembly 13 is the evaporimeter, blow out from new trend export 16 after the new trend refrigeration that gets into from new trend entry 15, for the kitchen provides cold wind, simultaneously, the flue gas that gets into first exhaust smoke passageway 221 from fan subassembly 21, dispel the heat to the condenser, take away and discharge from first exhaust smoke passageway 221 behind the heat, thereby improve the heat transfer effect of first heat exchange assembly 12, and then do benefit to and promote the air conditioner efficiency.

When the air conditioner stops working, the range hood is in a normal working mode, at this time, the first smoke exhaust channel 22 is closed and the second smoke exhaust channel 23 is opened through switching of the switching valve 3, and smoke exhausted from the fan 21 enters the second smoke exhaust channel 23 and is exhausted.

The smoke exhaust channel is provided with a smoke prevention device, wherein the smoke prevention device is a check valve arranged on the smoke exhaust channel, so that smoke is prevented from flowing backwards and tainting odor, and substances such as germs accumulated in a flue are prevented from returning to a kitchen.

In order to purify fresh air, a fresh air purification unit 19 is installed in the casing 10, and the fresh air purification unit 19 is located at the front end of the first heat exchanger 12, so that outdoor fresh air is purified by the fresh air purification unit 19 and then enters the first heat exchanger 12, and further flows out from the first air outlet 1601, and the air entering the kitchen is cleaner.

The range hood assembly 2 has a smoke evacuation channel 22. The second air outlet 1602 of the air conditioning assembly 1 is externally connected with a second air supply pipe 16022, and the second air supply pipe 16022 and the smoke exhaust passage 22 are combined into a smoke exhaust passage 2401 which is directly communicated with the outdoor or a common flue.
