Kitchen air conditioning system
Technical Field
The present invention relates to a kitchen air conditioning system.
Background
The kitchen is a main place for people to cook, the mood of a cooking person is directly influenced by the good or bad of the kitchen air environment, particularly in hot summer, the kitchen sultry environment brings great discomfort to the cooking person, and for this purpose, various kitchen air conditioners are invented by people to cool the kitchen air.
The existing kitchen air conditioner has no great difference from the common air conditioner in basic form, and is generally split by adopting an inner machine and an outer machine, namely the outer machine is positioned outdoors, the inner machine is positioned indoors, the inner machine and the outer machine are respectively provided with a motor fan, the split type kitchen air conditioner of the inner machine and the outer machine is connected in a pipeline mode, holes are formed in a wall to damage decoration, the outer machine is hung outside, the structure is not compact enough, and the whole kitchen air conditioner is not attractive. In addition, the existing kitchen air conditioner is provided with an outdoor air inlet and an indoor air outlet, outdoor fresh air enters the air conditioner through the outdoor air inlet and is supplemented into the kitchen from the indoor air outlet after heat exchange of the heat exchanger, namely, the air conditioner works in a fresh air mode, and for extreme weather in summer or cold, the energy consumption of the air conditioner is high due to the fact that the temperature of the outdoor air and the temperature of the indoor air are high, energy conservation is not facilitated, and heat generated by heat exchange of the air conditioner cannot be effectively utilized. It can be seen that the existing kitchen air conditioner is not organically combined with the range hood, and heat generated by the air conditioner heat exchanger cannot be discharged through the range hood.
In addition, as people pay more and more attention to energy conservation and environmental protection, people pay more and more attention to not only the pollution problem of the oil smoke discharge to the environment, but also the problem of heat waste caused by the oil smoke discharge, however, in the working process of the traditional range hood, the heat carried by the oil smoke discharged outside is not effectively utilized before being discharged into a public flue or outdoors, so that heat waste is caused.

Preferably, the air valve can be switched to the second air inlet to be communicated with the first air outlet, or switched to the second air inlet to be communicated with the second air outlet, and the first air inlet is communicated with the first air outlet.
In order to realize internal circulation, a ventilation opening communicated with the first air inlet is formed in the kitchen suspended ceiling.
Further preferably, both the compressor and the second heat exchanger are mounted above the kitchen ceiling.
In order to provide warm air for the inside of the cabinet or cupboard, the first heat exchanger is an evaporator and the second heat exchanger is a condenser. The warm air is sent into the cupboard or the cupboard, thereby having the effect of dehumidification or drying.
Compared with the prior art, the kitchen air conditioning system has the advantages that the total heat exchanger, the air conditioning system and the oil fume suction assembly are combined, the total heat exchanger is integrated on the oil fume suction assembly, the structure is more compact, two different working modes can be switched by switching the air valve, the oil fume suction assembly can be independently used, the oil fume is directly discharged outdoors, and the oil fume waste heat and the indoor air can be discharged to a cabinet or a cupboard through heat exchange, so that the dehumidification or drying effect is achieved, and the effective utilization of the oil fume waste heat is realized.

Detailed Description
The invention is described in further detail below with reference to the embodiments of the drawings.
Embodiment one:
As shown in fig. 1 and 2, the kitchen air conditioning system of the present embodiment includes an air conditioning assembly 1, a range hood assembly 2, and a total heat exchanger 3. The air conditioning assembly 1 comprises a compressor 11, a first heat exchanger 12 and a second heat exchanger 13, wherein the compressor 11, the first heat exchanger 12 and the second heat exchanger 13 are communicated through a refrigerant pipeline 14, and a four-way valve 15 is arranged on the refrigerant pipeline 14. The operation principle of the air conditioning assembly 1 is the same as that of the existing air conditioner, and will not be described again.
The fume exhaust assembly 2 adopts a fume exhaust fan, a centrifugal fan 20 is arranged in the fume exhaust fan, and a fume exhaust channel 21 is formed at the rear end of the outlet of the centrifugal fan 20. The fume purifying device 22, the total heat exchanger 3 and the first heat exchanger 12 are sequentially arranged in the fume exhaust passage 21 from front to back, so that fume pollution to the total heat exchanger 3 and the first heat exchanger 12 is avoided.
The total heat exchanger 3 comprises a shell 30, and a first air inlet 31, a second air inlet 32, a first air outlet 33 and a second air outlet 34 are formed in the shell 30. The first air inlet 31 is communicated with the kitchen room through the ventilation opening 51 of the kitchen ceiling 5, the second air inlet 32 is communicated with the smoke exhaust channel 21 of the smoke absorbing assembly 2, the first air outlet 33 is communicated with the outdoor or public flue through the smoke exhaust pipe 23, and the second air outlet 34 is communicated with the kitchen cabinet 4 or the interior of the kitchen cabinet.
A damper 35 for switching the direction of wind and a blower 36 for supplying wind are installed in the housing 30, and stoppers 37 for engaging with the damper 35 are installed on opposite inner side walls of the housing 30. When the air valve 35 is switched to the vertical position and abuts against the stop block 37, the second air inlet 32 is communicated with the first air outlet 33, and when the air valve 35 is switched to the horizontal position and leaves from the stop block 37, the second air inlet 32 is communicated with the second air outlet 34, and the first air inlet 31 is communicated with the first air outlet 33.
In this embodiment, the compressor 11 and the second heat exchanger 13 of the air conditioning assembly 1 are both mounted above the kitchen ceiling 5, and the second heat exchanger 13 is located in the air duct between the second air outlet 34 and the cabinet 4 air inlet 41 or the cupboard air inlet.
The kitchen air conditioning system is mainly used for supplying air to a kitchen cabinet 4 or a cupboard, and when the kitchen air conditioning system works, the first heat exchanger 12 is an evaporator, the second heat exchanger 13 is a condenser through switching the four-way valve 15, and the system can work in the following two different modes through switching the air valve 35:
in the first mode, the damper 35 is in the vertical position, the range hood is operated alone, the compressor 11 is not turned on, and the oil smoke in the range hood enters the total heat exchanger 3 through the second air inlet 32 and is then discharged to the outdoor or public flue through the first air outlet 33.
In the second mode, the air valve 35 is in a horizontal position, the purified air in the range hood completes the first heat exchange with the first heat exchanger 12, namely the evaporator, in the smoke exhaust channel 21, then enters the total heat exchanger 3 through the second air inlet 32, completes the second heat exchange with the indoor air entering the total heat exchanger 3 from the first air inlet 31, the indoor air after heat exchange is discharged to the outdoor or public flue from the first air outlet 33, the purified air after heat exchange is discharged from the second air outlet 34, finally completes the third heat exchange through the second heat exchanger 13, namely the condenser, and is discharged to the cabinet 4, thereby achieving the dehumidification effect, and the air is discharged to the cupboard, thereby achieving the drying effect.
Embodiment two:
