Detailed Description
In order to make the embodiments, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.
The air conditioner comprises an indoor unit, a water storage cavity and a humidifying module, wherein the water storage cavity and the humidifying module are arranged in the indoor unit; the water in the water storage cavity can be atomized into water vapor under the action of the humidifying module and diffused to the indoor heat exchanger. In addition, the air conditioner provided by the invention adopts a mode of frosting first and then defrosting to carry out self-cleaning on the indoor unit.
Referring to fig. 1, fig. 1 is a main flowchart of a self-cleaning control method of an air conditioner of the present invention. As shown in fig. 1, the self-cleaning control method of the air conditioner of the present invention includes the following steps: s110, after the air conditioner finishes self-cleaning, opening a storage cavity to mix a disinfectant with water in the water storage cavity to form disinfectant water; and S120, starting the humidifying module to enable the steam after the atomization of the sterilizing water to sterilize the indoor heat exchanger. According to the invention, after the air conditioner finishes self-cleaning, the humidification module is started to atomize the water mixed with the disinfectant to disinfect the indoor heat exchanger, so that bacteria on the indoor heat exchanger can be effectively removed, and the condition that the air conditioner brings the bacteria into the room to harm the health of users in the use process is avoided.
Further, after step S120, i.e., after the indoor heat exchanger is sterilized, the air conditioner is again started to self-clean to clean the sterilizing agent on the indoor heat exchanger. Namely, the water generated in the process of frosting and defrosting the air conditioner can effectively flush the disinfectant remained on the indoor heat exchanger.
In a specific embodiment, before performing step S110, the air conditioner self-cleaning control method of the present invention further includes: before the air conditioner performs self-cleaning, acquiring the current air humidity; when the air humidity is lower than the preset humidity, the storage cavity is not opened and the humidifying module is directly started to atomize water in the water storage cavity. In this case, since the humidity of the indoor air is dry, which may affect the frosting effect, it is necessary to humidify the indoor air and then perform the self-cleaning mode. It should be noted that the preset humidity can be flexibly set by those skilled in the art according to actual needs. For example, the air humidity value capable of meeting the frosting requirement of the air conditioner during self-cleaning is set according to the application scene of the air conditioner.
Further, before the humidifying module is directly started to atomize water in the water storage cavity, the self-cleaning control method of the air conditioner further comprises the following steps: acquiring water quality information in the water storage cavity; and judging whether to start the humidifying module according to the water quality information. Specifically, when the water quality information meets a preset water quality standard, a humidifying module is started; and when the water quality information does not meet the preset water quality standard, the humidifying module is not started. Because the self-cleaning effect of the air conditioner has a great relationship with the frosting intensity, and the frosting intensity has a great relationship with the indoor humidity, if the indoor air is humidified by adopting poor water quality, the indoor air is possibly polluted, dust in the air is brought in when frosting is caused, the self-cleaning effect is influenced, and the better cleaning effect can be achieved only by using clean water. Therefore, only when the water quality information meets the preset water quality standard, the humidification module is favorable for humidifying the indoor air, so that the situation of polluting the indoor air is prevented.
Further, the self-cleaning control method of the air conditioner of the invention further comprises the following steps: and sending out reminding information under the condition that the humidifying module is not started. Wherein, the reminding information is used for reminding the user to replace the water in the water storage cavity. As an example, the water in the water storage cavity is condensed water generated by a purified indoor unit heat exchanger, or the water in the water storage cavity is water added by a user. That is to say, the water in the water storage cavity may be condensed water of the collected indoor heat exchanger, or may be purified water actively added by the user.
In a specific embodiment, the indoor unit of the present invention is further provided with a dust suction device, and the dust suction device can suck dust on the indoor heat exchanger. Before step S110, the method for controlling self-cleaning of an air conditioner of the present invention further includes: before the air conditioner performs self-cleaning, starting a dust suction device; after the dust collection device collects dust for a preset time, detecting the dust concentration on the indoor heat exchanger; self-cleaning is selectively activated based on the dust concentration. It will be appreciated by those skilled in the art that the air conditioner performs self-cleaning, and for some larger contaminants (e.g., spiders), it is difficult to carry the water by defrosting. Therefore, the invention firstly utilizes the dust suction device to suck dust for a period of time before the air conditioner starts self-cleaning, thereby greatly improving the self-cleaning effect of the air conditioner. As an example, the first preset time may be flexibly set by a person skilled in the art, such as 1 minute, 2 minutes, and the like.
Specifically, after the dust suction device sucks dust for a certain period of time, if the dust concentration is lower than a preset concentration, the dust suction device is turned off and self-cleaning is started. When the dust concentration is higher than the preset concentration, the dust suction device continues to suck dust and detects the dust concentration on the indoor heat exchanger in real time, and when the dust concentration is lower than the preset concentration, the dust suction device is closed and self-cleaning is started. In other words, in order to ensure the self-cleaning effect, the dust suction degree of the dust suction device is judged before the self-cleaning is performed, namely, after the dust concentration on the heat exchanger is reduced to the preset concentration, the self-cleaning effect is performed to the best. The preset concentration can be set by a person skilled in the art according to actual needs, for example, the optimal dust concentration can be determined by detecting the self-cleaning effect of the heat exchanger under different dust concentrations in a test mode; or detecting that the dust collector starts to collect dust on the heat exchanger until the dust collector cannot continue to collect dust on the heat exchanger, wherein the dust concentration on the heat exchanger is that the dust collector cannot continue to clean, namely, self-cleaning needs to be started, so that the preset concentration can be set to be slightly higher than the dust concentration.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
