The case 7 needs to be adaptively adjusted or perforated according to the placement position of the internal components.

The working principle of the air radiator 5 with the cleaning device is described in detail below with reference to fig. 1 to 6.

When the air with oil smoke passes through the louver 8 and the filter screen 1.1 in the filter 1 under the action of the power source 4, the oil smoke in the air is adhered to the filter screen 1.1, and the clean air passes through the V-shaped heat exchanger 5.1 under the action of the power source 4 to refrigerate (summer) or heat (winter) and then is sent back to the kitchen, so that the temperature in the kitchen is reduced (summer) or increased (winter).

The oil smoke adhered to the filter screen 1.1 can not be accumulated for a long time, and must be cleaned regularly, and the long-time cleaning is difficult. Before the air radiator 5 is shut down after use, the controller 6 sends control signals to the control valve 2.7 and the detergent filling pump 2.8 to be started, so that tap water and detergent are fully mixed in the conveying pipe 2.1, the uniformly mixed detergent solution is uniformly sprayed onto the filter screen 1.1 through the spray head 2.2, oil stains attached to the filter screen 1.1 are cleaned, and the cleanness of the filter screen 1.1 is guaranteed. Wherein, the louver 8 plays a role in preventing the shower water from splashing outwards.

The mixed liquid with the oil stain which is cleaned off enters the sewage draining disk 3, and a high-low level switch is arranged in the sewage draining disk 3. The high-low level switch transmits water surface position information to the controller 6, and the controller 6 sends a signal to start the sewage pump 3.2 according to the received information, so that sewage is discharged to the outside through the sewage pipeline 3.3. When the liquid level in the sewage draining disc 3 reaches the high level of the high-low switch, the high-low switch transmits the water surface position information to the controller 6, the controller 6 sends a signal to close the control valve 2.7 and the detergent filling pump 2.8, the spraying is suspended, and the solution with oil stains is prevented from overflowing. And if the liquid level reaches the low level, the spraying is resumed until the set spraying time is reached. Wherein, the spraying time can be set in advance and controlled by the controller 6.

From this, it can be seen that air heat exchanger 5 is used to the cleaning device who has the lampblack removal function of this application helps improving air heat exchanger 5's heat exchange efficiency and life.

It should be noted that the cleaning device with the oil smoke removing function of the present application is mainly suitable for the requirements of air heat exchangers for cooling and heating in kitchens, and can also be suitable for the requirements of air treatment in environments similar to kitchens.
