Accompanying drawing explanation
Fig. 1 is the structural representation of plug one embodiment of the present invention;
Fig. 2 is the flow chart of control method one embodiment of the plug in Fig. 1.
Embodiment
In order to make technical scheme of the present invention clearer, below in conjunction with accompanying drawing, the control method of plug of the present invention, air conditioner and plug thereof is described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain that the present invention is not intended to limit the present invention.
Referring to Fig. 1 and Fig. 2, as shown in Figure 1, plug of the present invention comprises header body, Detection Circuit, controller and trip gear.Wherein, Detection Circuit 1, controller 2 and trip gear 3 are electrically connected to successively.Detection Circuit 1 is for detecting in real time the concentration of gas leakage, and the concentration of the gas leakage detecting is sent to controller 2.Controller 2 compares the concentration of the gas leakage detecting and preset standard value to judge and export control signal to trip gear 3.The output of trip gear 3 is connected to respectively the switch of connecting on power line.In the present embodiment, the quantity of switch is two, and one of them switch series is associated on the live wire of power line, and another switch series is associated on the zero line of power line.Disconnection and the closure of the control signal control switch that trip gear 3 is exported according to controller, thus realize the power-off of air conditioner and power on.
When the concentration of the gas leakage detecting surpasses preset standard value, the control signal of controller output is controlled trip gear the switch of power line is disconnected, and makes air conditioner power-off, has avoided the phenomenon of the air conditioner blast that the leakage of combustible refrigerant causes.When the concentration of the gas leakage detecting does not surpass preset standard value, the control signal of controller output is controlled trip gear and is failure to actuate, and the switch of power line, still in closed state, makes air conditioner normally carry out work.
By Detection Circuit built-in on plug, detect in real time the concentration of gas leakage, controller compares the rear output of judgement control signal by the concentration of the gas leakage detecting and preset standard value, trip gear is controlled disconnection and the closure of switch on power supply according to the control signal of controller output, thereby control the power-off of air conditioner and power on, having improved the reliability of refrigerator leak detection.When there is Leakage Gas fault, trip gear disconnects air conditioner and power supply, the situation of having avoided air conditioner to cause air conditioner to be blasted because of the leakage of flammable coolant.
As a kind of embodiment, Detection Circuit 1 comprises for detecting in real time the gas sensor of the concentration of gas leakage.Whether gas sensor is exposed in air, detect in real time cold-producing medium and leak, and the concentration of the gas leakage detecting is sent to controller 2.In the present embodiment, controller 2 is the controller that CPU (Central Processing Unit, central processing unit) or DSP (Digital Signal Processor, digital signal processor) etc. have the information processing function.Certainly, controller 2 can be also comparator or other logic analysis circuit with logic analysis function.
The invention still further relates to a kind of air conditioner, comprise the plug in compressor, motor, condenser, evaporator and above-described embodiment, plug is connected to the main body of air conditioner by power line.When plug is plugged on socket, air conditioner powers on.
More preferably, plug is arranged on the below of the main body of air conditioner.Owing to generally can sinking after combustible refrigerant leakage, therefore plug is arranged on to the below of the main body of air conditioner, guarantee reliability and accuracy that Leakage Gas detects.More preferably, plug be arranged on air conditioner the easy leak of cold-producing medium such as compressor, condenser or evaporator near, improve the detection effect of Leakage Gas and the reliability of detection.
The invention still further relates to a kind of controller of plug, the plug for above-described embodiment, comprises the steps:
S1, Detection Circuit detect the concentration of gas leakage in real time; In the present embodiment, gas sensor detects the concentration of gas leakage in real time, and the concentration of the gas leakage detecting is sent to controller.
S2, controller judge whether the concentration of gas leakage surpasses preset standard value, and the switch that if so, trip gear is controlled on power line according to the control signal of controller output disconnects, and air conditioner is out of service; If not, return to step S1.Controller compares the concentration of the gas leakage detecting and preset standard value, and when the concentration of gas leakage surpasses preset standard value, trip gear disconnects the switch on power line according to the control signal of controller output, and air conditioner power-off is out of service.When the concentration of gas leakage does not surpass preset standard value, return to step S1, Detection Circuit continues to detect the concentration of gas leakage.Now, trip gear is failure to actuate, and the switch on power line is still in closed state, and air conditioner normally moves.
In use, first plug is plugged on socket, the switch on power line is closed, and air conditioner is powered on.In initial condition, the switch on power line is in closure state.When the concentration of gas leakage surpasses preset standard value, the switch on power line disconnects.
The control method of plug of the present invention, air conditioner and plug, by Detection Circuit built-in on plug, detect in real time the concentration of gas leakage, controller compares the rear output of judgement control signal by the concentration of the gas leakage detecting and preset standard value, trip gear is controlled disconnection and the closure of switch on power supply according to the control signal of controller output, thereby control the power-off of air conditioner and power on, having improved the reliability of refrigerator leak detection.When there is Leakage Gas fault, trip gear disconnects air conditioner and power supply, the situation of having avoided air conditioner to cause air conditioner to be blasted because of the leakage of flammable coolant.
The above embodiment has only expressed several execution mode of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
