An air conditioner and a self-cleaning control method and apparatus thereof according to an embodiment of the present invention will be described with reference to the accompanying drawings.
First, the structure and operation of the indoor unit of the air conditioner will be briefly described with reference to the accompanying drawings.
As shown in fig. 3 to 5, the indoor unit 100 of the air conditioner includes an indoor heat exchanger B, a first fan D, a second fan E, and a fresh air fan F, wherein the first fan D is disposed at an upper portion of the indoor heat exchanger B, and the second fan E is disposed at a lower portion of the indoor heat exchanger B.
In addition, an air inlet mesh enclosure M is arranged at the rear side of the indoor heat exchanger B, and an air outlet mesh enclosure L covers the front ends of the first air outlet a21 and the second air outlet a22 and is connected to the front air outlet a 2. The first air outlet A21 is communicated with the air inlet A1, a first fan D is arranged in a first air channel A4 formed by communication, the second air outlet A22 is communicated with the air inlet A1, a second fan E is arranged in a second air channel A5 formed by communication, and the first fan D and the second fan E are respectively and independently controlled. It should be noted that the first fan D may be an axial flow fan, and the second fan E may be a centrifugal fan. As shown in fig. 4-5, a fresh air fan F (not shown) is disposed in the third air duct a6, and the fresh air fan F may be a centrifugal fan, wherein the first air duct a4 is located above the second air duct a5, and the third air duct a6 is located below the second air duct a 5.
In some embodiments of the present invention, after the air enters the indoor unit 100 from the air inlet mesh enclosure M, the air is exchanged heat by the indoor heat exchanger B to form wind flowing out from the front air outlet a2 of the front panel A8 and the air outlet mesh enclosure L. Specifically, the first fan D drives air to flow from the air inlet a1 to the front air outlet a2, that is, the air sent by the air inlet a1 can be driven by the first fan D and guided out from the front air outlet a2, and the second fan E drives air to flow from the air inlet a1 to the front air outlet a 2. In addition, the fresh air fan F can also introduce fresh air into the cavity where the indoor heat exchanger B is located and flow to the front air outlet A2.
Fig. 1 is a flowchart illustrating a self-cleaning control method of an air conditioner according to an embodiment of the present invention. As shown in fig. 1, the self-cleaning control method of an air conditioner according to an embodiment of the present invention includes the steps of:
and S1, after the air conditioner enters the self-cleaning mode, determining the self-cleaning stage of the air conditioner, wherein the self-cleaning stage of the air conditioner comprises a condensation stage.
It is understood that the condensing stage refers to a stage of condensing water generated by the indoor heat exchanger or the cavity in which the indoor heat exchanger is located.
And S2, when the air conditioner is in a condensation stage, controlling the air conditioner to perform refrigeration operation, wherein the first fan and the second fan are controlled to operate, and then the first fan is controlled to operate and the second fan stops operating or the first fan and the fresh air fan are controlled to operate and the second fan stops operating.
Wherein, in the condensation phase, the first fan is controlled to operate at a first target speed, and the second fan is controlled to operate at a second target speed, wherein the first target speed and the second target speed are determined based on the indoor ambient temperature and the indoor ambient humidity.
It is understood that after the air conditioner enters the self-cleaning mode, the indoor ambient temperature and the indoor ambient humidity are detected, and the target rotation speeds of the first fan and the second fan, i.e., the first target rotation speed and the second target rotation speed, are determined according to the indoor ambient temperature and the indoor ambient humidity. When the air conditioner enters a condensation stage, the air conditioner is controlled to perform refrigeration operation, wherein the compressor is controlled to operate at the highest frequency, the first fan is controlled to operate at a first target rotating speed, the second fan is controlled to operate at a second target rotating speed, and then the first fan is controlled to operate at the first target rotating speed and the second fan stops operating.
According to an embodiment of the present invention, controlling both the first fan and the second fan to operate, and then controlling the first fan to operate and the second fan to stop operating, or controlling both the first fan and the fresh air fan to operate and the second fan to stop operating includes: detecting the indoor environment temperature in the process of operating the first fan and the second fan; when the indoor environment temperature is reduced to a first temperature threshold value, the first fan is controlled to operate and the second fan stops operating or the first fan and the fresh air fan are controlled to operate and the second fan stops operating.
It can be understood that in the process of operating both the first fan and the second fan, the indoor environment temperature is detected in real time, when the indoor environment temperature is reduced to the first temperature threshold value, the first fan is controlled to continue to operate at the first target rotating speed and the second fan stops operating, at the moment, the first fan introduces the indoor air into the first air channel to be converged with the cold air, and the indoor heat exchanger cavity can generate condensed water.
Further, according to an embodiment of the present invention, controlling the first fan to operate and the second fan to stop operating or controlling both the first fan and the fresh air fan to operate and the second fan to stop operating includes: detecting the outdoor environment temperature and the outdoor environment humidity; when the outdoor environment temperature is greater than the second temperature threshold and the outdoor environment humidity is greater than the first humidity threshold, controlling the first fan to operate, stopping the second fan to operate, and controlling the fresh air fan to operate so as to introduce fresh air into the cavity where the indoor heat exchanger is located, thereby generating condensed water in the cavity; and when the outdoor environment temperature is less than or equal to the second temperature threshold or the outdoor environment humidity is less than or equal to the first humidity threshold, controlling the first fan to run and the second fan to stop running, and also controlling the fresh air fan to stop running.
It can be understood that after the operation of the first fan is controlled according to the indoor environment temperature and the second fan stops operating, the outdoor environment temperature and the outdoor environment humidity are detected, when the outdoor environment temperature is greater than the second temperature threshold and the outdoor environment humidity is greater than the first humidity threshold, namely, the outdoor environment temperature and the outdoor environment humidity belong to a preset high-humidity high-temperature range, the operation of the fresh air fan is controlled to introduce fresh air into a cavity where the indoor heat exchanger is located, the high-temperature high-humidity fresh air and cold air are intersected in the cavity, and therefore condensed water is generated in the cavity.
When the outdoor environment temperature is less than or equal to the second temperature threshold or the outdoor environment humidity is less than or equal to the first humidity threshold, namely the outdoor environment temperature and the outdoor environment humidity do not belong to the preset high-humidity high-temperature range, the first fan is controlled to operate, the second fan is controlled to stop operating, and the fresh air fan is also controlled to stop operating.
Therefore, by reasonably utilizing the three-air-channel system of the air conditioner, when the temperature of the indoor environment is reduced to the first temperature threshold value, the first fan is controlled to operate at the first target rotating speed, the second fan stops operating, cold air and hot air can be intersected, condensed water can be generated in the indoor heat exchanger and the indoor heat exchanger cavity, and when the outdoor environment is high temperature and high humidity, fresh air is introduced by controlling the operation of the fresh air fan, so that the condensed water can be generated in the indoor heat exchanger cavity (namely, the air channel), the indoor heat exchanger cavity is cleaned, and the cleaning effect is obvious.
According to an embodiment of the present invention, the self-cleaning stage of the air conditioner further includes a frost stage after the condensation stage, and the method further includes: and when the time for the air conditioner to perform the cooling operation in the condensation stage reaches a first operation time period t1, controlling the air conditioner to enter a frost stage.
Further, according to an embodiment of the present invention, the self-cleaning control method of an air conditioner further includes: acquiring the ambient temperature and the ambient humidity; the first operation time period t1 is determined according to the environmental temperature and the environmental humidity and through the target mapping relation.
It should be noted that the ambient temperature may be an outdoor ambient temperature, may also be an indoor ambient temperature, and the ambient humidity may be an outdoor ambient humidity, and may also be an indoor ambient humidity.
It can be understood that, when the amount of the condensed water is constant, the ambient humidity is higher, and the difference between the ambient temperature and the temperature of the indoor heat exchanger is higher, the first operation time period t1 is shorter; the smaller the ambient humidity and the smaller the difference between the ambient temperature and the indoor heat exchanger temperature, the larger the first operation time period t 1. Therefore, after the air conditioner enters the self-cleaning mode, the ambient temperature and the ambient humidity are detected, a mapping relation between the amount of condensed water and the first operation time period t1 can be established according to the ambient temperature and the ambient humidity, and the first operation time period t1 can be determined according to the mapping relation between the amount of condensed water and the first operation time period t 1.
According to one embodiment of the present invention, when the air conditioner is in a frost stage, the air conditioner is controlled to maintain a cooling operation, wherein the first fan and the second fan are controlled to reduce the rotation speed or the first fan and the second fan are controlled to stop operating.
It can be understood that the indoor heat exchanger and the cavity where the indoor heat exchanger is located can be frosted by controlling the first fan and the second fan to reduce the rotating speed or controlling the first fan and the second fan to stop running.
According to an embodiment of the present invention, after the defrosting stage, the self-cleaning stage of the air conditioner further includes a defrosting drying stage, and the method further includes: when the time for the air conditioner to perform the refrigerating operation in the defrosting stage reaches a second operation time t2, controlling the air conditioner to enter a defrosting and drying stage; and when the air conditioner is in a defrosting and drying stage, controlling the air conditioner to perform heating operation. The second operation time period t2 may be 10min, and may be specifically determined according to the type of the air conditioner.
It should be noted that, when the air conditioner is in the defrosting and drying stage, the first fan and the second fan can be controlled to operate simultaneously, wherein the rotating speeds of the first fan and the second fan can both be p%, and the value range of p can be 1-5.
It can be understood that after the defrosting stage is finished, the air conditioner enters a defrosting and drying stage, and the air conditioner is controlled to perform heating operation so as to defrost and dry the indoor heat exchanger.
Further, according to an embodiment of the present invention, when the time for the air conditioner to perform the heating operation in the defrosting and drying stage reaches the third operation time period t3, the air conditioner is controlled to perform the air supply until the time for the air conditioner to perform the air supply reaches the fourth operation time period t 4.
When the air conditioner is used for supplying air, the first fan and the second fan can be controlled to operate simultaneously.
It can be understood that when the time for the air conditioner to supply air reaches the fourth operation time period t4, the air conditioner may be controlled to exit the self-cleaning mode and enter the mode set by the user.
Wherein the third period of operation t3 and the fourth period of operation t4 are determined based on the indoor ambient humidity, according to an embodiment of the present invention.
It can be understood that the third operating time period t3 and the fourth operating time period t4 are positively correlated with the indoor ambient humidity, i.e., the greater the indoor ambient humidity is, the greater the third operating time period t3 and the fourth operating time period t4 are; the smaller the indoor ambient humidity is, the smaller the third operating time period t3 and the fourth operating time period t4 are, so that the third operating time period t3 and the fourth operating time period t4 can be determined according to the indoor ambient humidity after the indoor ambient humidity is acquired.
According to an embodiment of the present invention, the self-cleaning control method of an air conditioner further includes: sending out reminding information when the condition of the air conditioner is determined to meet the self-cleaning condition; receiving a self-cleaning instruction input by a user; and controlling the air conditioner to enter a self-cleaning mode according to the self-cleaning instruction.
It can be understood that after the air conditioner is started, the air conditioner firstly calculates a time interval t from the last self-cleaning mode, and judges whether the indoor heat exchanger needs to be cleaned according to the time interval t, namely, whether the state of the air conditioner meets the self-cleaning condition is judged, specifically, when the time interval t is greater than or equal to the preset time t', the state of the air conditioner is determined to meet the self-cleaning condition, and at the moment, a user can be reminded of cleaning the indoor heat exchanger in a voice or display mode.
