Abstract

An air conditioner defrosting control method and a device thereof. The air conditioner defrosting control method comprises: entering a defrosting mode, and detecting the number of defrosting operations executed in the present defrosting mode; according to the number of defrosting operations and an initially set defrosting time, setting the present set defrosting time recording the present defrosting time; detecting and determining that the present defrosting time reaches the present set defrosting time; updating the number of defrosting operations; and setting the next set defrosting time. By means of the air conditioner defrosting control method and device, the maximum defrosting time can be self-adaptively adjusted without affecting the use of a user, and preventing the accumulation of a frosting layer, and avoiding the risk of pipes bursting.

Claims

1. A defrosting control method for air conditioner, comprising:

entering a defrosting mode, and detecting a number of defrosting operations that have been performed in the defrosting mode;

setting a currently-set defrosting time according to the number of defrosting operations and an initially-set defrosting time;

recording a current defrosting time;

detecting and determining that a current defrosting time reaches the currently-set defrosting time;

updating the number of defrosting operations; and

setting a next-set defrosting time.

2. The method according to claim 1, wherein the setting a next-set defrosting time comprises:

setting the next-set defrosting time based on an updated number of defrosting operations and the initially-set defrosting time.

3. The method according to claim 1, further comprising:

confirming and exiting the defrosting mode;

detecting and determining that the current defrosting time does not reach the currently-set defrosting time; and

setting the next-set defrosting time as the initially-set defrosting time.

4. The method according to claim 3, after detecting and determining that the current defrosting time does not reach the currently-set defrosting time, further comprising:

resetting the number of defrosting operations to an initial setting.

5. The method according to claim 1, wherein the setting a currently-set defrosting time according to the number of defrosting operations and an initially-set defrosting time comprises:

obtaining a pre-set unit extension defrosting duration;

obtaining an extension defrosting time according to an unit extension defrosting duration and the number of defrosting operations; and

setting the currently-set defrosting time according to the extension defrosting time and the initially-set defrosting time.

6. The method according to claim 1, further comprising:

setting the initially-set defrosting time.

13. An air conditioner, comprising:

a processor;

a memory; and

a computer program stored in the memory and executable by the processor, wherein the computer program, when executed by the processor, causes a defrosting control method for air conditioner according to claim 1 to be performed.

14. A computer readable storage medium having stored therein a computer program that, when executed by a processor, causes a defrosting control method for air conditioner according to claim 1 to be performed.

7. A defrosting control device for air conditioner, comprising:

a defrosting device, configured to detect a number of defrosting operations that have been performed in a defrosting mode;

a first setting device, configured to set a currently-set defrosting time according to the number of defrosting operations and an initially-set defrosting time;

a recording device, configured to record a current defrosting time;

an updating device, configured to detect and determine that a current defrosting time reaches the currently-set defrosting time to update the number of defrosting operations; and

a second setting device, configured to set a next-set defrosting time.

8. The defrosting control device for air conditioner according to claim 7, wherein,

the second setting device is configured to set the next-set defrosting time based on an updated number of defrosting operations and the initially-set defrosting time.

9. The defrosting control device for air conditioner according to claim 7, further comprising:

an exiting device, configured to confirm and exit the defrosting mode;

a determining device, configured to detect and determine that the current defrosting time does not reach the currently-set defrosting time; and

a third setting device, configured to set the next-set defrosting time as the initially-set defrosting time.

10. The defrosting control device for air conditioner according to claim 9, wherein,

the third setting device is configured to reset the number of defrosting operations to an initial setting.

11. The defrosting control device for air conditioner according to claim 7, wherein

a first setting device is configured to obtain a pre-set unit extension defrosting duration, obtain an extension defrosting time according to a unit extension defrosting duration and the number of defrosting operations, and set the currently-set defrosting time according to the extension defrosting time and the initially-set defrosting time.

12. The defrosting control device for air conditioner according to claim 7, further comprising:

a setting device, configured to set the initially-set defrosting time.
