Namely, whether the germicidal lamp needs to be started to operate or not is directly judged according to the interval time.
The technical solution of the present invention is described in detail below with reference to two specific embodiments.
Example one
As shown in fig. 4, the control method of the present embodiment includes the steps of:
s100: and when receiving the self-cleaning instruction, enabling the air conditioner to execute a self-cleaning program.
The self-cleaning command may be automatically triggered, for example, a self-cleaning judgment condition is set, and when the self-cleaning command is met, the self-cleaning command is automatically triggered, or the self-cleaning command may be sent by the user.
S200: and acquiring the interval time between the self-cleaning program execution at this time and the self-cleaning program execution at the previous time.
Illustratively, a timer is set in the controller, and the timer is started after the air conditioner executes the self-cleaning program, and is stopped until the next time the air conditioner executes the self-cleaning program, and the data is cleared.
S310: and judging whether the interval time is greater than a first preset value.
After the interval time is acquired, comparing the interval time with a first preset value, judging the size of the interval time and the first preset value, and determining whether the germicidal lamp needs to be started to operate according to a judgment result, specifically, if the interval time is greater than the first preset value, executing step S320, namely, starting the germicidal lamp to operate; otherwise, if the interval time is not greater than the first preset value, step S330 is performed, i.e., the germicidal lamp is not started to operate.
It should be noted that, in practical applications, a person skilled in the art may flexibly set a specific numerical value of the first preset value according to experiments or experiences, as long as whether the germicidal lamp needs to be started or not can be determined by the critical point determined by the first preset value.
S320: and starting the germicidal lamp.
When the interval time is greater than the first preset value, it indicates that the time since the last self-cleaning procedure is executed is relatively long, that is, the time for storing dust is relatively long, in this case, the possibility of bacteria breeding on the heat exchanger is relatively high, and the germicidal lamp needs to be started to operate to sterilize the heat exchanger, so that the cleaning effect of the heat exchanger is improved.
S330: the germicidal lamp is not activated.
When the interval time is less than or equal to the first preset value, the time for executing the self-cleaning program is not too long, in this case, the possibility of bacteria growing on the heat exchanger is low, the starting operation of the germicidal lamp can not be carried out, and therefore energy can be saved.
Preferably, in a situation where the germicidal lamp needs to be started, the control method of the embodiment further includes: calculating the difference between the interval time and a first preset value; acquiring preset time and/or preset power corresponding to the difference value; the germicidal lamp is operated for a preset time and/or at a preset power.
When sterilizing the heat exchanger, the germicidal lamp may be operated at a fixed time, the operating power of the germicidal lamp may be adapted to the difference between the interval time and the first predetermined value, even if the germicidal lamp is operated at a predetermined power corresponding to the difference between the interval time and the first predetermined value, or the germicidal lamp may be operated at a fixed power, the operating time of the germicidal lamp may be adapted to the difference between the interval time and the first predetermined value, even if the germicidal lamp is operated at a predetermined time corresponding to the difference between the interval time and the first predetermined value, or both the operating time and the operating power of the germicidal lamp may be adapted to the difference between the interval time and the first predetermined value, even if the germicidal lamp is operated at a predetermined time and a predetermined power corresponding to the difference between the interval time and the first predetermined value, which may be flexibly adjusted and changed without departing from the principles and scope of the present invention, should be limited within the scope of the present invention.
Taking the example that the operation time and the operation power of the germicidal lamp are both adapted to the difference between the interval time and the first preset value, in practical application, the preset time and the preset power operation corresponding to the difference between the interval time and the first preset value can be obtained according to a formula or a comparison table, etc.
Illustratively, as shown in fig. 5, three intervals are set for a difference value between the interval time and the first preset value, the first interval, the second interval and the third interval are sequentially set from small to large, three values are set for the preset time, T1, T2 and T3 are sequentially set from small to large, three values are set for the preset power, and P1, P2 and P3 are sequentially set from small to large, and after the value of the difference value is calculated, the corresponding specific values of the preset time and the preset power can be queried according to the preset time and the preset power comparison table. Specifically, when the difference is located in a first interval, the germicidal lamp is operated according to the preset time T1 and the preset power P1, when the difference is located in a second interval, the germicidal lamp is operated according to the preset time T2 and the preset power P2, and when the difference is located in a third interval, the germicidal lamp is operated according to the preset time T3 and the preset power P3.
Example two
As shown in fig. 6, the control method of the present embodiment includes the steps of:
s100: and when receiving the self-cleaning instruction, enabling the air conditioner to execute a self-cleaning program.
The self-cleaning command may be automatically triggered, for example, a self-cleaning judgment condition is set, and when the self-cleaning command is met, the self-cleaning command is automatically triggered, or the self-cleaning command may be sent by the user.
S200: and acquiring the interval time between the self-cleaning program executed this time and the self-cleaning program executed last time.
Illustratively, a first timer is arranged in the controller, the timer is started after the air conditioner executes the self-cleaning program, the timer is stopped until the next time the air conditioner executes the self-cleaning program, and the data is cleared.
S310: and judging whether the interval time is greater than a first preset value.
After the interval time is acquired, comparing the interval time with a first preset value, judging the size of the interval time and the first preset value, and determining whether the germicidal lamp needs to be started to operate according to a judgment result, specifically, if the interval time is greater than the first preset value, executing step S320, namely, starting the germicidal lamp to operate; otherwise, if the interval time is not greater than the first preset value, step S330 is performed.
S320: the germicidal lamp is started to operate.
When the interval time is greater than the first preset value, it indicates that the time since the last self-cleaning procedure is executed is relatively long, that is, the time for storing dust is relatively long, in this case, the possibility of bacteria breeding on the heat exchanger is relatively high, and the germicidal lamp needs to be started to operate to sterilize the heat exchanger, so that the cleaning effect of the heat exchanger is improved.
S330: and acquiring the accumulated time when the humidity of the room is greater than the preset humidity in the time period between the self-cleaning program execution and the previous self-cleaning program execution.
When the interval time is less than or equal to the first preset value, it indicates that the time since the last self-cleaning procedure was performed is not too long, in this case, it is necessary to further acquire the accumulated time during which the humidity of the room is greater than the preset humidity in the time period between the current self-cleaning procedure and the previous self-cleaning procedure, and then selectively start the operation of the germicidal lamp according to the accumulated time. By taking room humidity into account on the basis of the interval time, the accuracy of the determination can be improved.
The air conditioner is characterized in that a humidity sensor is arranged on a shell of the indoor unit, the humidity sensor is in communication connection with the controller and can transmit a detected humidity value of a room to the controller, a second timer is further arranged in the controller, after the air conditioner executes a self-cleaning program, when the humidity of the room is larger than a preset humidity, the second timer is used for timing, and when the humidity of the room is smaller than or equal to the preset humidity, the second timer is stopped for timing.
It should be noted that, similarly to the interval time, the judgment can be directly made according to the accumulated time, or the judgment can also be made according to the difference between the accumulated time and the standard time, etc., and such flexible adjustment and change can be made without departing from the principle and scope of the present invention, and should be limited within the protection scope of the present invention.
S340: whether the accumulated time is greater than a second preset value.
And after the accumulated time is acquired, comparing the accumulated time with a second preset value, namely directly judging according to the accumulated time, judging the size of the accumulated time and the size of the accumulated time, and selectively starting the germicidal lamp according to a judgment result.
Specifically, if the accumulated time is greater than the second preset value, which indicates that although the time since the last self-cleaning procedure was performed is not too long, the room is wet within the time, and in this case, the possibility of bacteria growth on the heat exchanger is also high, step 320 is performed, even if the germicidal lamp is started; otherwise, if the accumulated time is not greater than the second preset value, step S350 is performed, i.e., the germicidal lamp is not enabled to operate.
S350: the germicidal lamp is not activated.
When the interval time is less than or equal to the first preset value and the accumulated time is less than or equal to the second preset value, the time for executing the self-cleaning program is not too long, and the room is dry in the period of time, in this case, the possibility of bacteria growing on the heat exchanger is low, the germicidal lamp is not started to operate, and energy can be saved.
It should be noted that, in practical applications, a person skilled in the art may flexibly set the specific values of the first preset value, the second preset value and the preset humidity according to experiments or experiences, as long as the critical point determined by combining these values can determine whether the germicidal lamp needs to be started.
Preferably, in a situation where the germicidal lamp needs to be started, the control method of the embodiment further includes: calculating the difference between the interval time and a first preset value, and recording the difference as a first difference; calculating the difference between the accumulated time and a second preset value, and recording as a second difference; acquiring preset time and/or preset power corresponding to the first difference and the second difference; and operating the germicidal lamp for a preset time and/or at a preset power.
Similarly to the embodiment, when the heat exchanger is sterilized, the germicidal lamp may be operated for a fixed time, the operating power of the germicidal lamp may be adapted to the first difference and the second difference, even if the germicidal lamp is operated at the preset power corresponding to the first difference and the second difference, or the germicidal lamp may be operated at the fixed power, the operating time of the germicidal lamp may be adapted to the first difference and the second difference, even if the germicidal lamp is operated at the preset time corresponding to the first difference and the second difference, or both the operating time and the operating power of the germicidal lamp may be adapted to the first difference and the second difference, even if the germicidal lamp is operated at the preset time and the preset power corresponding to the first difference and the second difference, which may be flexibly adjusted and changed without departing from the principle and scope of the present invention.
Taking the example that the operation time and the operation power of the germicidal lamp are both adapted to the first difference and the second difference, in practical application, the preset time and the preset power operation corresponding to the first difference and the second difference can be obtained according to a formula or a look-up table, etc.
