The present invention also provides a control method for an air conditioner, as shown in Figure 3, the control method of the present invention includes the following steps:

S100: Enabling the air conditioner to execute a self-cleaning program when a self-cleaning instruction is received.

Among them, the self-cleaning instruction can be triggered automatically, such as setting the self-cleaning judgment condition, when the condition is met, the self-cleaning instruction is automatically triggered, or the user can also send the self-cleaning instruction, this flexible adjustment and change does not deviate from the present invention The principle and scope of all should be limited within the protection scope of the present invention.

S200: Obtain the time interval between the execution of the self-cleaning program this time and the previous execution of the self-cleaning program.

Exemplarily, a timer is set in the controller, which starts counting after the air conditioner executes the self-cleaning program, and stops counting when the air conditioner executes the self-cleaning program next time, and clears the data.

S300: Selectively start and run the germicidal lamp according to the interval time.

At the same time or after the air conditioner executes the self-cleaning program, it can be determined whether it is necessary to start the germicidal lamp to sterilize the heat exchanger according to the interval between the current self-cleaning program and the previous self-cleaning program. When the heat exchanger needs to be sterilized, the heat exchanger can be sterilized in time through the germicidal lamp. Through such a setting, not only the dust on the heat exchanger can be cleaned, but also the bacteria on the heat exchanger can be cleaned. Clean up to achieve the effect of deep cleaning of the heat exchanger and improve the cleaning effect of the heat exchanger.

It should be noted that the judgment can be made directly according to the interval time, or can be judged according to the difference between the interval time and the standard time, etc., and this flexible adjustment and change does not deviate from the principles and principles of the present invention. scope, should be limited within the protection scope of the present invention.

Preferably, the step of "selectively starting and running the germicidal lamp according to the interval time" specifically includes: judging whether the interval time is greater than a first preset value; and selectively starting and running the germicidal lamp according to the judgment result. That is, it is directly judged according to the interval time whether it is necessary to start and run the germicidal lamp.

The technical solution of the present invention will be described in detail below in conjunction with two specific embodiments.

Embodiment one

As shown in Figure 4, the control method of this embodiment includes the following steps:

S310: Determine whether the interval time is greater than a first preset value.

After obtaining the interval time, compare the interval time with the first preset value, judge the size of the two, and determine whether to start the germicidal lamp according to the judgment result, specifically, if the interval time is greater than the first preset value , then execute step S320, even if the germicidal lamp is started to run; on the contrary, if the interval time is not greater than the first preset value, then execute step S330, that is, not to start the germicidal lamp to run.

It should be noted that in practical applications, those skilled in the art can flexibly set the specific value of the first preset value according to experiments or experience, as long as the critical point determined by the first preset value can determine whether it is necessary to make the sterilization The lights start running.

S320: Start and run the germicidal lamp.

When the interval time is greater than the first preset value, it means that the self-cleaning program has been executed for a long time since the last time, that is, the dust has accumulated for a long time. In this case, the possibility of bacteria growing on the heat exchanger is relatively high. Large, it is necessary to start the operation of the germicidal lamp to sterilize the heat exchanger and improve the cleaning effect of the heat exchanger.

S330: Do not start and run the germicidal lamp.

When the interval time is less than or equal to the first preset value, it means that the time since the last execution of the self-cleaning program is not too long. The lamp starts to run, thereby saving energy.

Preferably, when the germicidal lamp needs to be activated, the control method of this embodiment further includes: calculating the difference between the interval time and the first preset value; obtaining the preset time corresponding to the difference and/or or preset power; make the germicidal lamp run for a preset time and/or preset power.

When sterilizing the heat exchanger, the germicidal lamp can be operated according to a fixed time, so that the operating power of the germicidal lamp can be adapted to the difference between the interval time and the first preset value, even if the germicidal lamp operates according to the interval time and the first preset value The difference between the first preset values corresponds to the preset power operation, or the germicidal lamp can also be operated according to a fixed power, so that the difference between the operating time of the germicidal lamp and the interval time and the first preset value Adapted, even if the germicidal lamp runs according to the preset time corresponding to the difference between the interval time and the first preset value, or, the running time and the running power of the germicidal lamp can be both related to the interval time and the first preset value The difference between a preset value is adapted, even if the germicidal lamp operates according to the preset time and preset power corresponding to the difference between the interval time and the first preset value, this flexible adjustment and change Without departing from the principle and scope of the present invention, all should be limited within the protection scope of the present invention.

Take the running time and running power of the germicidal lamp as an example to match the difference between the interval time and the first preset value. The difference between the preset values corresponds to the preset time and preset power operation.

Exemplarily, as shown in Figure 5, three intervals are set for the difference between the interval time and the first preset value, which are the first interval, the second interval and the third interval in order from small to large, and for the preset There are three values for the time setting, which are T1, T2 and T3 in order from small to large. There are three values for the preset power setting, which are P1, P2 and P3 in order from small to large. After calculating the value of the difference, you can according to The corresponding preset time and preset power comparison table is queried to obtain specific values of the corresponding preset time and preset power. Specifically, when the difference is in the first interval, the germicidal lamp is operated according to the preset time T1 and the preset power P1; when the difference is in the second interval, the germicidal lamp is operated according to the preset time T2 and the preset power P2 Running, when the difference is in the third interval, make the germicidal lamp run according to the preset time T3 and the preset power P3.

Embodiment two

As shown in Figure 6, the control method of this embodiment includes the following steps:

Among them, the self-cleaning instruction can be automatically triggered, such as setting the self-cleaning judgment condition, when the condition is met, the self-cleaning instruction is automatically triggered, or the user can also send the self-cleaning instruction, this flexible adjustment and change does not deviate from the present invention The principle and scope of all should be limited within the protection scope of the present invention.

Exemplarily, a first timer is set in the controller, which starts counting after the air conditioner finishes executing the self-cleaning program, and stops counting when the air conditioner executes the self-cleaning program next time, and clears the data.

S310: Determine whether the interval time is greater than a first preset value.

After obtaining the interval time, compare the interval time with the first preset value, judge the size of the two, and determine whether to start the germicidal lamp according to the judgment result, specifically, if the interval time is greater than the first preset value , then execute step S320, even if the germicidal lamp starts to run; otherwise, if the interval time is not greater than the first preset value, execute step S330.

S320: Start and run the germicidal lamp.

S330: Obtain the accumulative time during which the humidity of the room is greater than the preset humidity in the time period between the execution of the self-cleaning program this time and the previous execution of the self-cleaning program.

When the interval time is less than or equal to the first preset value, it means that the time since the last execution of the self-cleaning program is not too long. In this case, it is necessary to further obtain the current execution of the self-cleaning program and the previous execution The humidity of the room in the period between is greater than the cumulative time of the preset humidity, and then the germicidal lamp is selectively started to run according to the cumulative time. By adding the consideration of the room humidity on the basis of the interval time, the accuracy of the judgment can be improved.

Exemplarily, a humidity sensor is provided on the housing of the indoor unit, and the humidity sensor communicates with the controller to transmit the detected humidity value of the room to the controller, and a second timer is also provided in the controller, After the air conditioner executes the self-cleaning program, when the humidity of the room is greater than the preset humidity, the second timer is counted, and when the humidity in the room is less than or equal to the preset humidity, the second timer is stopped.

It should be noted that, similar to the interval time, it can be judged directly based on the accumulated time, or it can be judged based on the difference between the accumulated time and the standard time, etc. This flexible adjustment and change does not Deviation from the principle and scope of the present invention should be limited within the protection scope of the present invention.

S340: Whether the accumulated time is greater than a second preset value.

After the accumulated time is obtained, the accumulated time is compared with the second preset value, that is, the judgment is made directly according to the accumulated time, the size of the two is judged, and the germicidal lamp is selectively activated according to the judgment result.

Specifically, if the accumulated time is greater than the second preset value, it means that although the time since the last execution of the self-cleaning procedure is not too long, the room is relatively humid during this period of time. In this case, the heat exchange If the possibility of bacteria growing on the device is also relatively high, execute step 320, even if the germicidal lamp is started; on the contrary, if the accumulated time is not greater than the second preset value, then execute step S350, that is, do not start the germicidal lamp.

S350: Do not start and run the germicidal lamp.

When the interval time is less than or equal to the first preset value and the cumulative time is less than or equal to the second preset value, it means that the time since the last execution of the self-cleaning program is not too long, and, during this period, the room is relatively Drying, in this case, the possibility of bacteria growing on the heat exchanger is relatively small, and the germicidal lamp can not be started to operate, thereby saving energy.

It should be noted that in practical applications, those skilled in the art can flexibly set the specific values of the first preset value, the second preset value and the preset humidity according to experiments or experience, as long as the values determined by combining these values The critical point can determine whether it is necessary to start and run the germicidal lamp.

Preferably, in the case that the germicidal lamp needs to be started to run, the control method of this embodiment further includes: calculating the difference between the interval time and the first preset value, which is recorded as the first difference; calculating the cumulative time and the first preset value The difference between the two preset values is recorded as the second difference; obtain the preset time and/or preset power corresponding to the first difference and the second difference; make the germicidal lamp follow the preset time and/or Or preset power operation.

Similar to Embodiment 1, when the heat exchanger is sterilized, the germicidal lamp can be operated according to a fixed time, so that the operating power of the germicidal lamp can be adapted to the first difference and the second difference, even if the germicidal lamp is in accordance with The first difference and the second difference correspond to the preset power operation, or the germicidal lamp can also be operated according to a fixed power, so that the running time of the germicidal lamp is adapted to the first difference and the second difference, even if The germicidal lamp runs according to the preset time corresponding to the first difference and the second difference, or, the running time and the running power of the germicidal lamp can also be adapted to the first difference and the second difference, Even if the germicidal lamp operates according to the preset time and preset power corresponding to the first difference and the second difference, this flexible adjustment and change does not deviate from the principle and scope of the present invention, and should be limited within the scope of the present invention within the scope of protection.

Taking the operating time and operating power of the germicidal lamp as an example, both the first difference and the second difference are compatible. In practical applications, the first difference and the second difference can be obtained according to formulas or comparison tables. The corresponding preset time and preset power operation.

Exemplarily, as shown in FIG. 7, three intervals are set for the first difference between the interval time and the first preset value, which are the first time interval, the second time interval and the third time in order from small to large. Intervals, there are three intervals set for the second difference between the accumulated time and the second preset value, which are the first humidity interval, the second humidity interval and the third humidity interval in order from small to large, and there are three intervals for the preset time Five values, from small to large, are T1, T2, T3, T4 and T5. There are five values for the preset power setting, from small to large, they are P1, P2, P3, P4 and P5. After the calculation, the first After the values of the first difference and the second difference, specific values of the corresponding preset time and preset power can be queried according to the preset time and preset power comparison table.
