Embodiment 1

[0037] figure 1 It is a flow chart of the cleaning method for the heat exchanger in the air-conditioning room in Embodiment 1 of the present invention. Such as figure 1 As shown, the cleaning method of the air-conditioning indoor heat exchanger in Embodiment 1 of the present invention comprises the following steps:

[0038] Step S101, the user sets "cleaning".

[0039] Step S102, when the controller receives the "cleaning" instruction, control the air conditioner to operate in cooling mode, turn off the indoor fan, and control the frequency of the compressor to be the frosting frequency F 结霜 , making frost on the surface of the indoor heat exchanger;

[0040] Step S103, judging whether frosting is completed.

[0041] Preferably, judging whether the frosting is complete is as follows: when the temperature T of the inner tube of the indoor heat exchanger 内管 ≤The second preset temperature T S2 , and maintain the second preset time t under this temperature condition S2 , th...

Embodiment 2

[0052] figure 2 It is a flow chart of the cleaning method for the heat exchanger in the air-conditioning room in the second embodiment of the present invention. Such as figure 2 As shown, the steps of the cleaning method for the heat exchanger in the air-conditioning room in the second embodiment of the present invention are generally the same as those in the first embodiment, except that a condensation step is provided before the frosting step. details as follows:

[0053] Step S201, the user sets "cleaning".

[0054] Step S202, when the controller receives the "cleaning" instruction, control the air conditioner to operate in the cooling mode, and control the indoor fan to operate at the lowest gear, so that water is deposited on the surface of the indoor heat exchanger and frost does not form. In the condensation stage, water will precipitate on the surface of the indoor heat exchanger while no frost will form, so that there will be a certain amount of water hanging bet...

Embodiment 3

[0065] According to the above method embodiment of the present invention, the present invention also provides a cleaning device for a heat exchanger in an air-conditioning room, image 3 It is a structural schematic diagram of a cleaning device for a heat exchanger in an air-conditioning room according to Embodiment 3 of the present invention.

[0066] Such as image 3 As shown, the cleaning device includes a frosting module 31, a defrosting module 32, and a sterilization module 33. The frosting module 31 is used to control the operation of the air conditioner in the cooling mode, turn off the indoor fan, and make the surface of the indoor heat exchanger frost, and judge Whether frosting is completed; the defrosting module 32 is used to control the operation of the air conditioner in heating mode, turn on the indoor fan, convert the frost on the surface of the indoor heat exchanger into water, and judge whether the defrosting is completed; the sterilization module 33 is used t...

Abstract

The invention discloses a cleaning method and device for an indoor heat exchanger of an air conditioner. The cleaning method for the indoor heat exchanger of the air conditioner comprises the steps that 1, the air conditioner is controlled to operate in a refrigerating mode, an indoor draught fan is switched off, the surface of the indoor heat exchanger is frosted, and whether frosting is completed is judged; 2, after frosting is completed, the air conditioner is controlled to operate in a heating mode, the indoor draught fan is switched on, the frost on the surface of the indoor heat exchanger is converted into water, and whether defrosting is completed is judged; 3, after defrosting is completed, the temperature T of an inner tube of the indoor heat exchanger is controlled to be a first preset temperature TS1, the temperature TS1 of the inner tube of the indoor heat exchanger is kept for a first preset time tS1, and cleaning is completed. By the adoption of the cleaning method for the indoor heat exchanger of the air conditioner, cleaning of the indoor heat exchanger of the air conditioner can be achieved, no part is additionally arranged, cost is not increased, the high-temperature sterilizing function is achieved, and the comfort and health of a user are further improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a cleaning method and device for a heat exchanger in an air conditioning room. Background technique [0002] When the existing air conditioner is working, the indoor heat exchanger is in contact with the air in real time for heat exchange. Due to the dust in the air, after long-term deposition, the heat exchange efficiency of the indoor heat exchanger will be reduced, and bacteria will easily breed in it, which will affect people's health. [0003] At present, most air conditioners use filters to remove impurities in the air. However, very fine floating dust and bacteria suspended in the air cannot be filtered out, so the cleaning effect is not ideal. [0004] In order to solve the above problems, a Chinese patent (CN101256061A) discloses a cleaning method for an air-conditioning evaporator, which first rapidly cools, uses the water vapor in the air to quickly frost or ...
