With reference to fig. 1 to 5, an embodiment of the present disclosure provides an indoor unit of an air conditioner, including a casing 10, a purification structure 20, and a fan.

The housing 10 is provided with an air outlet 11.

The purification structure 20 is installed at the air outlet 11, and the purification structure 20 is used for generating the charged water mist.

The fan is arranged in the shell 10 and can rotate forwards and backwards; when the fan rotates forwards, the flow path of the charged water mist is at least partially overlapped with the air outlet path of the indoor unit of the air conditioner; when the fan rotates reversely, the flow path of the electrified water mist is at least partially overlapped with a second air inlet path of the indoor unit of the air conditioner.

It can be understood that the electrified water mist generated by the purification structure 20 can perform the function of disinfection and sterilization, and the purification structure 20 is disposed at the air outlet 11 of the indoor unit of the air conditioner, so that the air conditioner can perform purification for a corresponding target by controlling the fan to rotate forward or backward.

For example, when the air conditioner is in a purification mode, the fan rotates forwards, so that the electrified water mist enters the room where the indoor unit of the air conditioner is located along the air outlet path to purify the indoor air; when the self-cleaning mode of the air conditioner is started, the fan rotates reversely, so that the electrified water mist enters the indoor unit of the air conditioner from the air outlet 11 along with the second air inlet path to sterilize parts such as the heat exchanger, the fan air duct and the like, on the basis, the environment humidity inside the air conditioner can be increased, the frosting thickness of the heat exchanger is increased, the frosting time of the heat exchanger is saved, and the self-cleaning effect is improved.

By adopting the air-conditioning indoor unit provided by the embodiment of the disclosure, the air outlet 11 of the air-conditioning indoor unit is provided with the purification structure 20 and is matched with the fan capable of rotating in two directions, so that the air conditioner can simultaneously have the functions of sterilizing indoor air and sterilizing the internal structure of the air-conditioning indoor unit, and when the air-conditioning indoor unit is used, the purification mode or the self-cleaning mode can be started as required, the fan is controlled to rotate forwards or backwards, and a target is sterilized. This kind of design can be through electrified water smoke to the inside disinfection of machine in the air conditioning, reduces the inside bacterial growing of machine in the air conditioning, improves the cleanliness factor of air conditioner air supply, and this kind of design is less to the inner structure change of machine in the air conditioning, can save manufacturing cost.

Optionally, the purifying structure 20 is installed at one side of the air outlet 11, and the outlet of the purifying structure 20 faces the other side of the air outlet 11. Thus, after the electrified water mist is emitted from the purification structure 20, the electrified water mist can move along the air outlet path or the second air inlet path of the air conditioner, and then reach the designated position for disinfection and purification.

Optionally, the purification structure 20 includes an atomizing part 22 and a discharging part 23, the atomizing part 22 includes a first atomizing sheet 221 and a second atomizing sheet 221 which are arranged in parallel, and the atomizing part 22 is used for generating water mist; the discharge section 23 is connected to the atomizing section 22, and the discharge section 23 is used to charge the mist.

As an example, the atomizing part 22 is provided with at least two atomizing plates 221, and the number of the opening of the atomizing plates 221 can be controlled according to the humidity of the indoor air when in use. Theoretical analysis shows that the smaller the atomization amount, the smaller the droplet diameter and the higher the ionization degree of the water mist, the higher the air purification and sterilization efficiency, but when the droplet diameter is too small, the movement locus is very unstable under the influence of the gravity and the wind speed, and the droplets are vaporized or blown away to a great extent when not passing through an electric field region. At 15m²For example, under the condition that the indoor environment temperature is not changed by 25 ℃, the indoor and outdoor ventilation volume and the ventilation frequency are not considered, if the indoor relative humidity is lower than 20%, and if the relative humidity is increased to more than 40%, the humidification requirement can be met by opening the two atomization sheets 221; if the relative humidity is greater than 20% and less than 40%, the requirement can be met by opening one atomizing sheet 221 for humidification.

Optionally, the purification structure 20 further includes a first housing 10 and a second housing 10, one end of the first housing 10 is provided with a water inlet 211, and the other end is connected with the atomization portion 22; the second casing 10 is connected to the discharge portion 23, and the second casing 10 is used for discharging the charged mist.

It can be understood that the purification structure 20 is provided with a first housing 21, an atomization portion 22, a discharge portion 23 and a second housing 24 in sequence, the first housing 21 is provided with a water inlet 211 connected with a water source, the atomization portion 22 atomizes water provided by the water source to generate water mist, the discharge portion 23 can discharge electricity to charge the water mist, and the second housing 24 guides a release position of the charged water mist.

It can be understood that there are two ways for the water tank 40 to determine the time of water supplement, one is to detect the water level of the water tank 40 in real time through a water level sensor to supplement water; the other is to calculate the theoretical water usage time period from the capacity of the water tank 40 and the water consumption rate of the purification structure 20 and compare the theoretical water usage time period with the accumulated operating time period to determine whether water replenishment is required.

As an example, the water tank 40 is provided with a water level switch, which is in a closed state when the water tank 40 is replenished with water; when the water tank 40 is in a butt joint state with the purification structure 20, if the water level in the water tank 40 is low, the water level switch closes the water outlet 43, the purification structure 20 stops generating water mist, and the controller reminds a user to supplement water in a light, sound or information pushing mode and the like; if the water level in the water tank 40 is high, the water level switch is turned on, so that the water tank 40 can supply water to the purification structure 20, and the purification structure 20 can generate water mist or charged water mist.

As another example, the purification structure 20 is provided with at least two atomizing plates 221 for generating water mist. When in use, the number of the open atomizing plates 221 can be controlled according to the indoor air humidity.

Assuming that the volume of the water tank 40 is 450ml and the atomization amount of the single atomization sheet 221 is 150ml/h, the water replenishing time is determined according to the atomization amount of the atomization sheet 221 and the accumulated opening time of the atomization sheet 221. The specific calculation logic is as follows: starting 1 atomization plate 221, wherein the theoretical water use time period t is 450/150 h, that is, when the accumulated working time of the atomization plate 221 in the current period reaches 3h, the controller sends a water supplementing instruction, and meanwhile, the atomization plate 221 stops working until the water supplementing is completed; and 2 atomizing plates 221 are opened, the theoretical water use time period t is 450/300 and 1.5h, namely when the accumulated working time of the atomizing plates 221 in the current period reaches 1.5h, the controller sends out a water supplementing instruction, and meanwhile, the atomizing plates 221 stop working until the water supplementing is completed.
