Description

Technical Field

[0001] The invention relates to a kitchen air conditioning system. Background Art

[0002] The kitchen is the main place where people cook. The quality of the kitchen air environment directly affects the mood of the cook, especially in the hot summer, the stuffy environment of the kitchen brings great discomfort to the cook. For this reason, people have invented various kitchen air conditioners to cool the kitchen air.

[0003] The basic form of the existing kitchen air conditioner is not much different from that of ordinary air conditioners. Generally, the internal and external units are separated, that is, the external unit is located outdoors, and the internal unit is located indoors. The internal and external units each have a motor fan. The connection method of the kitchen air conditioner with internal and external units separated needs to be connected through pipes, and holes need to be opened on the wall, which damages the decoration. An external unit needs to be hung outside. The structure is not compact enough and the overall appearance is not beautiful. In addition, the existing kitchen air conditioners all have outdoor air inlets and indoor air outlets. The outdoor fresh air enters the air conditioner internal unit through the outdoor air inlet, and is replenished to the kitchen from the indoor air outlet after heat exchange in the heat exchanger. That is, the air conditioner works in the fresh air mode. For extreme weather such as hot summer or cold, due to the large temperature between the outdoor air and the indoor air, the air conditioner energy consumption is high, which is not conducive to energy saving, and the heat generated by the air conditioner heat exchange cannot be effectively utilized. It can be seen that the existing kitchen air conditioner is not organically combined with the range hood, and the heat generated by the air conditioner heat exchanger cannot be discharged through the range hood.

[0004] In addition, as people pay more and more attention to energy conservation and environmental protection, people not only pay attention to the pollution of the environment caused by the exhaust of oil smoke, but also begin to pay more and more attention to the problem of heat waste caused by the exhaust of oil smoke. However, during the operation of the current range hood, the heat carried by the exhaust oil smoke is not effectively utilized before being discharged into the public flue or outdoors, resulting in heat waste. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a kitchen air conditioning system which can effectively utilize the waste heat of cooking fumes and can cool, heat and provide fresh air for the kitchen in view of the above-mentioned existing technical status.

[0007] Preferably, a fan for providing wind power is also installed inside the housing.

[0008] In order to enable the air valve to smoothly switch the wind direction, a stopper for cooperating with the air valve is installed on the opposite inner side walls of the shell.

[0009] In order to prevent the oil smoke from polluting the first heat exchanger in the smoke exhaust channel, the oil smoke purification unit is arranged at the front end of the first heat exchanger.

The second heat exchanger 13 is arranged above the kitchen ceiling 4, and the second heat exchanger 13 is installed in the air inlet passage at the front end of the first air inlet 31 and close to the first air inlet 31.

[0026] The shell 30 of the total heat exchanger 3 is internally installed with a wind valve 35 for switching wind direction and a fan 36 for providing wind force, and a stopper 37 for cooperating with the wind valve 35 is installed on the opposite inner side wall of the shell 30. When the wind valve 35 is switched to a vertical position, the second air inlet 32 ​​is connected to the second air outlet 34, and when the wind valve 35 is switched away from the stopper 37 and is in a horizontal position, the first air inlet 31 is connected to the second air outlet 34, and the second air inlet 32 ​​is connected to the first air outlet 33.

[0027] When the kitchen air conditioning system is working, by switching the air valve 35 and the four-way valve 15, the system can be switched between the following three different working modes.

[0028] The first mode is the internal circulation mode. At this time, the air valve 35 is in a vertical position, the range hood works alone, the compressor 11 is not turned on, and the oil smoke in the range hood passes through the oil smoke purification unit 22 and enters the total heat exchanger 3 from the second air inlet 32, and supplies air to the kitchen through the second air outlet 34, forming an internal circulation.

[0029] The second mode is the heating mode, the first heat exchanger 12 is the evaporator, the second heat exchanger 13 is the condenser, the air valve 35 is in a horizontal position, the purified air in the range hood completes the first heat exchange with the evaporator in the smoke exhaust channel 21, and then enters the total heat exchanger 3 through the second air inlet 32, the outdoor fresh air enters the total heat exchanger 3 after the second heat exchange through the condenser, and undergoes the third heat exchange with the air entering the total heat exchanger 3 from the second air inlet 32, and finally provides warm air to the kitchen through the second air outlet 34, and the oil fume gas entering from the second air inlet 32 ​​is discharged through the first air outlet 33.

[0030] The third mode is the cooling mode, the first heat exchanger 12 is a condenser, the second heat exchanger 13 is an evaporator, the air valve 35 is in a horizontal position, and the purified air in the range hood completes the first heat exchange with the condenser in the smoke exhaust channel 21, and then enters the total heat exchanger 3 through the second air inlet 32. The outdoor fresh air enters the total heat exchanger 3 after the second heat exchange through the evaporator, and undergoes a third heat exchange with the air entering the total heat exchanger from the second air inlet 32, and finally provides cold air to the kitchen through the second air outlet 34, and the oil fume gas entering from the second air inlet 32 ​​is discharged to the outdoors through the first air outlet 33.

[0031] Embodiment 2:

[0032] like Figure 3 and Figure 4 As shown, the total heat exchanger 3 of this embodiment is different from that of the first embodiment. A fresh air purification unit 5 is installed in the air inlet channel at the front end of the second heat exchanger 13, and the air valve 35 can be switched to connect the first air inlet 31 with the first air outlet 33, and the second air inlet 32 ​​with the second air outlet 34, or switched to connect the first air inlet 31 with the second air outlet 34.

[0033] When the kitchen air conditioning system is working, the system can be switched between the three working modes of external circulation mode, heating mode and cooling mode by switching the air valve 35 and the four-way valve 15. In the external circulation mode, the first air inlet 31 is connected to the second air outlet 34, and the outdoor fresh air is purified by the fresh air purification unit 5 and then replenished into the room; in the heating and cooling modes, the first air inlet 31 is connected to the first air outlet 33, and the second air inlet 32 ​​is connected to the second air outlet 34. Its specific working principle is the same as that of the first embodiment, and will not be described in detail here.
