Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1-3, for the utility model discloses a preferred embodiment of an indoor unit of air conditioner, this indoor unit of air conditioner includes organism 1, fan 2, filter screen 3, heat exchanger 4, ultrasonic wave generation mechanism.

The machine body 1 has a cavity 10 formed therein, the cavity 10 has an air inlet 11 with an upward opening at the top and an air outlet 12 with a substantially horizontal opening at the bottom. Thus, the air outlet 12 and the air inlet 11 are vertically distributed, in order to reduce wind resistance, the part of the inner wall surface of the chamber 10 is an arc-shaped surface 10a which is smoothly bent from top to bottom, the upper edge of the arc-shaped surface 10a is opposite to the air inlet 11, and the lower edge is opposite to the air outlet 12. So that the air flow entering from the air inlet 11 smoothly flows out of the air outlet 12 along the arc-shaped face 10 a. The air outlet 12 is provided with a door body 6 capable of opening and closing the air outlet 12, and the periphery of the door body 6 is provided with a sealing ring 61, so that the door body 6 is in sealing fit with the edge of the air outlet 12 when being closed; the air inlet 11 is provided with an air inlet baffle 7 capable of opening and closing the air inlet 11, and the periphery of the air inlet baffle 7 is provided with a sealing ring, so that the air inlet baffle 7 is in sealing fit with the air inlet 11 when closed. Meanwhile, the upper portion of the chamber 10 is connected with a water inlet pipe 13, and the lower portion is connected with a water outlet pipe 14. The water inlet pipe 13 is connected with a water pump 131 and a first valve 132 for controlling the on-off of the water inlet pipe 13. The outer end of the water inlet pipe 13 is connected with the water tank 8 (or connected with a tap water faucet and the like). The drain pipe 14 is connected to a second valve body 141 for controlling opening and closing of the drain pipe 14. In this embodiment, the first valve element 132 and the second valve element 141 are both solenoid valves.

In the cavity 10 was all located to above-mentioned filter screen 3, fan 2, heat exchanger 4, the structure of filter screen 3, fan 2, heat exchanger 4 can refer to the structure in the current air conditioner indoor set, and for preventing when wasing that fan 2, heat exchanger 4 intake and can't use, the waterproof treatment is done to the junction of fan 2, heat exchanger 4 and electric wire. The filter screen 3 is transversely arranged below the air inlet 11, the heat exchanger 4 is arranged below the filter screen 3, and the fan 2 is arranged below the heat exchanger 4, so that the positions where the filter screen 3, the fan 2 and the heat exchanger 4 are located are lower than the position height of the air inlet 11. In this way, when the chamber 10 is filled with water, the water can flow over the filter net 3, the fan 2 and the heat exchanger 4 without overflowing from the air inlet 11. To operate the heat exchanger 4, a refrigerant inflow pipe 15 and a refrigerant outflow pipe 16 are connected to the chamber 10.

The ultrasonic generating mechanism is disposed outside the chamber 10, and includes an ultrasonic generator (not shown) and a vibrating head 5 (i.e., an ultrasonic transducer), wherein the vibrating head 5 is attached to an outer wall of the chamber 10, so that the generated ultrasonic waves can be transmitted into the chamber 10. The vibrating head 5 has at least two vibrating heads vertically distributed along the arc-shaped surface 10 a. Thus, the vibrating head 5 is not in the duct in which the wind flows.

The working method of the air-conditioning indoor unit comprises the following steps:

before self-cleaning is started, the air outlet 12 is closed, the first valve body 132 is opened, the water pump 131 is started, water is injected into the chamber 10 from the water inlet pipe 13, after the filter screen 3 is submerged in water in the chamber 10, the water pump 131 and the first valve body 132 are closed, and the air inlet 11 is closed. The air inlet 11 is closed after water is filled, so that air in the chamber 10 can be smoothly discharged from the air inlet 11 during water filling, and thus water can smoothly enter the chamber 10.

And (3) cleaning procedure: the ultrasonic generating mechanism is started, and the cavitation action, the acceleration action and the direct current action of the ultrasonic in the water are utilized to directly and indirectly act on the liquid and the dirt, so that the dirt layer is dispersed, emulsified and stripped to achieve the purpose of cleaning. Meanwhile, the fan 2 rotates to drive water to do vortex motion in the chamber 10, so that dust on the fan 2, the filter screen 3, the heat exchanger 4, the inner wall of the chamber 10 and the fins of the heat exchanger is washed away. After the cleaning is continuously carried out for 15min, the ultrasonic generating mechanism and the fan 2 are closed, the air inlet 11 is opened, the second valve body 141 is opened, the sewage is discharged, and after the sewage is discharged, the second valve body 141 is closed;

rinsing procedure: the first valve body 132 is opened, the water pump 131 is started, water is injected into the chamber 10 from the water inlet pipe 13, after the filter screen 3 is submerged in the water in the chamber 10, the water pump 131 and the first valve body 132 are closed, and the air inlet 11 is closed. Then, the blower 2 is turned on for 5min, the blower 2 is turned off, the air inlet 11 is opened, the second valve body 141 is opened, and the sewage is discharged.

And (3) drying procedure: after the sewage is completely discharged, a heating mode of an indoor unit of the air conditioner is started, the fan 2 is started, hot air with the temperature exceeding 56 ℃ is blown out to completely dry and sterilize the chamber 10, and then the fan 2 is closed. The self-cleaning procedure is completed.
