Embodiment 1

[0018] figure 1 is a flowchart of a defrosting control method according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps (step S101-step S103):

[0019] Step S101, monitoring the temperature of the outdoor motor;

[0020] Step S102, if the accumulated temperature of the outdoor motor within the first specified time period is less than or equal to zero, enter the defrosting mode;

[0021] Step S103, if the accumulative temperature of the outdoor motor is greater than or equal to zero within the second specified time period, exit the defrosting mode.

[0022] In this embodiment, the infrared temperature sensor is used to detect the temperature of the outdoor motor, so as to perform defrosting operation and exit the defrosting operation, achieve the purpose of accurate defrosting, and improve the heating effect and reliability of the unit.

[0023] The monitoring of the temperature of the outdoor motor can be realize...

Embodiment 2

[0030] figure 2 is a flow chart of defrosting in heating mode according to an embodiment of the present invention, such as figure 2 As shown, the process includes the following steps (step S201-step S206):

[0031] Step S201, in the heating mode, after the outdoor motor runs for a preset time, the temperature of the outdoor motor is detected by the infrared temperature sensor.

[0032] Step S202, judging the temperature T of the outdoor motor 红 Whether ≤0 holds; if yes, execute step S203; if not, execute step S201.

[0033] Step S203, judging whether the cumulative duration is satisfied, that is, within the cumulative duration T 红 Whether ≤0 is always established; if yes, execute step S204; if not, execute step S201.

[0034] Step S204, enter the defrosting mode (that is, the cooling mode).

[0035] Step S205, detecting T 红 After >0, it is judged whether the accumulative duration (for example, 20s) is met; if yes, execute step S206; if not, execute step S204.

Embodiment 3

[0039] corresponds to figure 1 The defrosting control method introduced, this embodiment provides a defrosting control device, such as image 3 The structural block diagram of the defrosting control device shown, the device includes:

[0040] The monitoring module 10 is used to monitor the temperature of the outdoor motor;

[0041] The defrosting module 20, connected to the monitoring module 10, is used to enter the defrosting mode when the temperature of the outdoor motor is less than or equal to zero within the accumulated first specified time period;

[0042] The exit module 30 is connected to the defrost module 20, and is used for exiting the defrost mode when the temperature of the outdoor motor is greater than or equal to zero within a second specified period of time.

[0043] In this embodiment, the infrared temperature sensor is used to detect the temperature of the outdoor motor, so as to perform defrosting operation and exit the defrosting operation, achieve the pu...

Abstract

The invention discloses a defrosting control method and device. The defrosting control method includes the steps that the temperature of an outdoor motor is monitored; if the temperature of the outdoor motor is smaller than or equal to zero within an accumulated first appointed time length, the defrosting mode is started; and if the temperature of the outdoor motor is larger than or equal to zero within an accumulated second appointed time length, the defrosting mode is stopped. According to the technical scheme, an infrared temperature sensor is arranged on a condenser, the temperature of the outdoor motor is detected through the infrared temperature sensor, and then defrosting starting operation and defrosting stopping operation are carried out. The purpose of accurate defrosting is realized, and the heating effect and reliability of a unit are improved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a defrosting control method and device. Background technique [0002] At present, when the air conditioner and other electrical equipment are under low-temperature heating conditions, the condenser will appear frosting. After the condenser is frosted, the heating effect will be reduced, and the compressor will return liquid and other adverse conditions. In this case, it is necessary to deal with The condenser is defrosted to ensure the heating effect and reliable operation of the unit. Now the common defrosting method is to detect the temperature of a pipeline in the condenser of the outdoor unit and the setting time, so as to switch the mode. The defrosting accuracy of this method is low, and the defrosting effect is poor. [0003] For the problem of low defrosting accuracy in the prior art, no effective solution has been proposed yet. Contents of the invention [0004] Embod...
