Description

Technical Field

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

[0002] As people pay more and more attention to energy conservation and environmental protection, people not only pay attention to the pollution of oil fume exhaust to the environment, but also begin to pay more and more attention to the problem of heat waste caused by oil fume exhaust. However, during the operation of the current range hood, the heat carried by the exhaust oil fume is not effectively utilized before being discharged into the public flue or outdoors, resulting in heat waste. For example, taking the existing kitchen air conditioning system as an example, an air conditioner is installed in the kitchen, and the kitchen air conditioner is used to air condition the kitchen air. Although, in summer, the air outlet of the air conditioner can blow out cold air to cool the kitchen air, and in winter, the air outlet of the air conditioner can blow out hot air to heat the kitchen air, thereby improving the user experience, 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. At the same time, the exhaust of oil fume with heat from the range hood itself also causes energy waste. In summary, the existing kitchen air conditioning system needs to be further improved. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a kitchen air conditioning system with a compact structure and capable of effectively utilizing the waste heat of kitchen fumes in view of the above-mentioned existing technical status.

[0005] Preferably, the total heat exchanger is arranged in the second smoke exhaust channel.

[0006] In order to prevent oil smoke from contaminating the total heat exchanger, an oil smoke purification unit is installed in the second smoke exhaust channel, and the oil smoke purification unit is located at the front end of the total heat exchanger.

[0007] Preferably, the total heat exchanger comprises a shell, on which the first air inlet, the second air inlet, the first air outlet and the second air outlet are provided, and the first air valve is arranged inside the shell.

[0008] Further preferably, a fan for providing wind power is also installed inside the housing.

[0009] In order to smoothly switch the wind direction when the first air valve is deflected, a stopper for cooperating with the first air valve is installed on the opposite inner side wall of the shell.

[0010] In order to connect the first air outlet and the first smoke exhaust channel with the outside or a public smoke duct, the first smoke exhaust channel is connected with the outside or the public smoke duct through a smoke exhaust pipe, and the first air outlet is connected with the smoke exhaust pipe.

[0011] Preferably, an air supply outlet connected to the second air outlet is opened on the kitchen ceiling.

[0015] Figure 2 It is a schematic structural diagram of a total heat exchanger according to an embodiment of the present invention. DETAILED DESCRIPTION

[0016] The present invention is further described in detail below with reference to the accompanying drawings.

[0017] like Figure 1 and Figure 2As shown, the kitchen air conditioning system in this embodiment includes a total heat exchanger 1 and an oil fume suction component 2. The total heat exchanger 1 is integrated as an air conditioning component on the oil fume suction component 2. The shell 11 of the total heat exchanger 1 is provided with a first air inlet 12, a second air inlet 13, a first air outlet 14 and a second air outlet 15. The first air inlet 12 is connected to the outside, the first air outlet 14 is connected to the outside or a public flue, and the second air outlet 15 is connected to the kitchen room through the air supply port 31 on the kitchen ceiling 3.

[0018] A first air valve 16 for switching wind direction and a fan 17 for providing wind force are installed inside the housing 11, and a stopper 18 for cooperating with the first air valve 16 is installed on the opposite inner side wall of the housing 11. When the first air valve 16 is switched to a vertical position and abuts against the stopper 18, the second air inlet 13 is connected to the second air outlet 15; when the first air valve 16 is switched to be separated from the stopper 18 and is in a horizontal position, the second air inlet 13 is connected to the first air outlet 14, and the first air inlet 12 is connected to the second air outlet 15.

[0019] The fume extraction assembly 2 of the present embodiment adopts a top-suction range hood, in which a centrifugal fan 20 is installed, and the outlet rear end of the centrifugal fan 20 has a first smoke exhaust channel 21 and a second smoke exhaust channel 22. The first smoke exhaust channel 21 is connected to the first air outlet 14, and both the first smoke exhaust channel 21 and the first air outlet 14 are connected to the outside or a public flue through a smoke exhaust pipe 26. The second smoke exhaust channel 22 is connected to the second air inlet 13. A total heat exchanger 1 and a fume purification unit 25 are installed in the second smoke exhaust channel 22, and the fume purification unit 25 is located at the front end of the total heat exchanger 1, so that the fume enters the total heat exchanger 1 after being purified. The fume purification unit 25 can adopt various existing fume purification devices, such as an electrostatic purification device.

[0020] A second air valve 24 is installed inside the oil fume suction assembly 2. By switching the second air valve 24, one of the first smoke exhaust channel 21 and the second smoke exhaust channel 22 can be connected to the oil fume suction port 23. In this embodiment, when the second air valve 24 is turned to the left, the first smoke exhaust channel 21 is connected to the oil fume suction port 23, and when the second air valve 24 is turned to the right, the second smoke exhaust channel 22 is connected to the oil fume suction port 23.

[0021] When the kitchen air conditioning system is working, by switching the first air valve 16 and the second air valve 24, the system can work in the following three different modes:

[0022] In the first mode, the second air valve 24 is opened to the left, that is, the first smoke exhaust channel 21 of the oil fume suction component 2 is connected with the smoke exhaust pipe 26, and the first air valve 16 is in a vertical position. At this time, the second smoke exhaust channel 22 is closed, and the oil fume suction component 2 is used alone. The oil fume exhausted from the first smoke exhaust channel 21 is discharged to the outside or the public flue through the smoke exhaust pipe 26.

[0023] In the second mode, the second air valve 24 is opened to the right, that is, the second smoke exhaust channel 22 of the fume suction assembly 2 is connected to the second air inlet 13 of the total heat exchanger 1, and the first air valve 16 is positioned vertically. At this time, the smoke exhausted from the second smoke exhaust channel 22 is purified by the fume purification unit 25 and then enters the interior of the total heat exchanger 1, and then supplies air to the kitchen room through the second air outlet 15.

[0024] In the third mode, the second air valve 24 is deflected to the right, that is, the second smoke exhaust channel 22 of the oil fume suction component 2 is connected with the second air inlet 13 of the total heat exchanger 1, and the first air valve 16 is in a horizontal position. At this time, the oil fume suction component 2 is combined with the total heat exchanger 1, and the oil fume discharged from the second smoke exhaust channel 22 is purified by the oil fume purification unit 25 and enters the total heat exchanger 1 through the second air inlet 13, and is discharged through the first air outlet 14. The outdoor air enters the total heat exchanger 1 from the first air inlet 12 and exchanges heat with the airflow entering the total heat exchanger 1 from the second smoke exhaust channel 22. After heat exchange, air is supplied to the kitchen from the second air outlet 15 to achieve the purpose of heating the kitchen.
