Based on above-mentioned hardware configuration, the embodiment of compressor of air conditioner guard method of the present invention is proposed.
It is the flow diagram of compressor of air conditioner guard method first embodiment of the present invention referring to Fig. 2, Fig. 2.
In the first embodiment, the compressor of air conditioner guard method the following steps are included:
S100: current indoor environment temperature and current air-conditioning inner tube temperature are obtained；
It should be noted that the current indoor environment temperature, refers to the temperature of the indoor environment at current time, it is described
Current environmental temperature specifically can be by being installed on outside air conditioner or the temperature transducer of the return air inlet of air conditioner etc. is surveyed
?.The current air-conditioning inner tube temperature refers to the temperature of the air-conditioning inner tube at current time, the current air-conditioning inner tube temperature tool
Body can be measured by being installed on the temperature transducer at air-conditioning inner tube.According to the difference of air conditioner specific structure, the air-conditioning
Inner tube is specifically as follows the indoor coil of air conditioner.

When overload protection occurs for compressor of air conditioner, current indoor environment temperature is usually of substantially equal with current air-conditioning inner tube temperature, institute
It states temperature gap and is usually closer to zero.And when by the operation of compressor of air conditioner refrigeration effect can be generated, current indoor ring
Border temperature should be greater than current air-conditioning inner tube temperature.
S300: the duration that the temperature gap is less than or equal to first threshold temperature, and holding statistics are counted
Continue duration as low effect duration；
It should be noted that first threshold temperature is preset threshold values, first threshold temperature can be cannot
The definite value modified, or the value that can be modified.In the concrete realization, air conditioner can have multiple and different refrigeration
Mode, first threshold temperature present mode of air conditioner can determine according to.Low effect duration refers to described
Temperature gap is less than or equal to the entire duration of first threshold temperature, as, is less than or equal to institute from the temperature gap
At the beginning of stating the first threshold temperature, until the temperature gap is less than or equal to the whole of the current time of first threshold temperature
The duration of a duration.
S400: when low effect duration is more than or equal to low effect duration threshold values, to the current machine stop times of storage into
Row increases certainly；
It will be appreciated that being less than or equal to first threshold temperature according to the temperature gap, it can be determined that refrigeration effect out
Fruit is unobvious, so as to judge that overload protection has occurred in compressor of air conditioner, therefore carries out certainly to the current machine stop times of storage
Increase.As long as being less than or equal to first threshold temperature with the temperature gap, directly judge that compressor of air conditioner is overloaded
The technical solution of protection is compared, and in the present embodiment, judges whether compressor of air conditioner has occurred overload protection according to low effect duration,
Erroneous judgement to overload protection is less likely to occur.This is because the temperature gap is less than or equal to first threshold temperature, it can also
Can be as the power supply of air conditioner it is temporarily unstable caused by transient phenomenon, and overload protection does not occur for compressor of air conditioner.
It should be noted that low effect duration threshold values is preset threshold values, low effect duration threshold values can be
The definite value that cannot be modified, or the value that can be modified.Since the executing subject of the present embodiment is that compressor of air conditioner is protected
Equipment is protected, the current machine stop times are stored in the compressor of air conditioner protection equipment.Increasing certainly for the current machine stop times can
It, every time can not also from the amount increased can be every time 1 from the amount increased, such as from 5 from increasing to 6 by being realized from program is increased
It is 1, for example increases to 7 certainly from 5.
S500: when the current machine stop times are more than or equal to machine stop times threshold values, control compressor of air conditioner power-off, to protect
Protect compressor of air conditioner.
It will be appreciated that being more than or equal to machine stop times threshold values according to the current machine stop times, it can be determined that air conditioner compressed
Continually overload protection has occurred in machine, at this point, control compressor of air conditioner power-off can protect compressor of air conditioner.
It should be noted that machine stop times threshold values is preset threshold values, the machine stop times threshold values can be that cannot be repaired
The definite value changed, or the value that can be modified.The present invention to control compressor of air conditioner power-off concrete mode with no restriction,
Specifically, control switch, the control switch and the compressor of air conditioner can be set in the power supply line of compressor of air conditioner
Equipment is protected to be electrically connected, such compressor of air conditioner protection equipment can be powered off by the control switch to compressor of air conditioner.
In the concrete realization, in this step, failure can be reported while controlling compressor of air conditioner power-off, to make air-conditioning
The user or maintenance personnel of device are handled in time.To avoid compressor of air conditioner by overprotection, and influence the normal of user
It uses, the current machine stop times of storage can be reset in the case where meeting certain condition, excessive to avoid compressor of air conditioner
Protection, such as current machine stop times can automatic clears, or the automatic clear after the power-off of entire air conditioner at regular intervals.
In the present embodiment, temperature gap, and root are calculated by current indoor environment temperature and current air-conditioning inner tube temperature
Judge whether compressor of air conditioner has occurred overload protection according to the duration that temperature gap is less than or equal to first threshold temperature,
And when current machine stop times are excessive, control compressor of air conditioner power-off can be avoided compressor of air conditioner because continually overloading
It protects and is damaged.Also, detecting compressor of air conditioner is not needed due to judging whether compressor of air conditioner has occurred overload protection
Size of current perhaps voltage swing is so as to avoid that current transformer or pressure switch are arranged on air conditioner, in turn
The saving for realizing air conditioner cost simplifies the production process of air conditioner, improves the production efficiency of air conditioner.
Further, as shown in figure 3, proposing that compressor of air conditioner guard method second of the present invention is implemented based on first embodiment
Example, in the present embodiment, after step S400, specifically includes:
S600: when the current machine stop times are less than machine stop times threshold values, the first preset duration is waited, and waiting institute
State the step of acquisition current indoor environment temperature and current air-conditioning inner tube temperature are returned after the first preset duration.
It should be noted that first preset duration can be zero in this step, i.e., without waiting, directly return to institute
State the step of obtaining current indoor environment temperature and current air-conditioning inner tube temperature.First preset duration is set greater than
Zero value can reduce the burden that compressor of air conditioner guard method is performed.
In the present embodiment, by returning to the step for obtaining current indoor environment temperature and current air-conditioning inner tube temperature
Suddenly, the compressor of air conditioner guard method is enabled constantly to be executed, so that it is lasting so that compressor of air conditioner is obtained
Protection.
Further, as shown in figure 4, proposing that compressor of air conditioner guard method third of the present invention is implemented based on first embodiment
