The specific embodiment

The present invention will be described in more detail below in conjunction with accompanying drawing and embodiment.

According to the 1st embodiment of the present invention, as shown in Figure 1, refrigerator involved in the present invention has the automatic fire alarm safety device, and it comprises: fire sensitive parameter detection probe 1, control module 2, warning device 3.Can a fire sensitive parameter detection probe 1 be installed at refrigerator fire-prone position, also can a plurality of fire sensitive parameter detection probe 1 be installed at the fire-prone position as required, in refrigerator top, Machine Room.Said 1 pair of fire sensitive parameter of fire sensitive parameter detection probe (like smokescope, temperature etc.) constantly detects in real time; And constantly send testing result to control module 2; Carry out the judgement of fire by control module 2; After can being set in advance surpass a certain safe range, be regarded as just judging that fire takes place.When control module 2 is judged to be after fire takes place, send alarm signal to warning device 3 (like the high-decibel buzzer etc.), inform the generation of refrigerator user fire, in time carry out proper process.Control module 2 also can cut off the refrigerator power supply automatically after judging that fire takes place, prevent bigger disaster.In addition, control module can directly utilize the existing control circuit of refrigerator, need not add extra circuit unit.In addition, can also have fire alarm disengage button 4 on the electric refrigerator housing body, under the situation that wrong report takes place, press this button and can remove wrong report, make refrigerator get into normal mode of operation.

In the present embodiment, fire sensitive parameter detection probe 1 is arranged on the refrigerator top platform 101.Because refrigerator top platform 101 is often placed baking box, micro-wave oven etc., so be easy to breaking out of fire.As shown in Figure 2, refrigerator body is connected with hinge at the top with refrigerator doors, and fire sensitive parameter detection probe 1 is installed in the hinged cover 102 of drift angle.Being arranged on like this do not influence under the situation that detects effect, and fire sensitive parameter detection probe 1 is not exposed on the external, and platform space, top still can access utilization, and opening the door of refrigerator closed the door does not have impairment yet.

According to the 2nd embodiment of the present invention, as shown in Figure 3, refrigerator involved in the present invention has detection probe in Machine Room 201, and it comprises fire sensitive parameter detection probe 1, hydrocarbon coolant leakage detection probe 5.Said fire sensitive parameter detection probe 1 is preferably with hydrocarbon coolant leakage detection probe 5 and is installed on 201 interior positions near triple valve 203, Machine Room.This is because coolant leakages take place easily for triple valve 203, and refrigerant is in case after leaking, and is easy to produce fiery core and causes fire.Said 1 pair of fire sensitive parameter of fire sensitive parameter detection probe (like smokescope, temperature etc.) constantly detects in real time; 5 pairs of hydrocarbon coolant leakage concentration of said hydrocarbon coolant leakage detection probe constantly detect in real time; And constantly send testing result to control module 2, carry out the judgement of fire by control module 2.Control module 2 is according to the detection information of any one probe in said two kinds of detection probe, judges whether breaking out of fire.That is to say, if fire sensitive parameter detection probe 1 and hydrocarbon coolant leakage detection probe 5 both one of the information that detected surpass safe range, then be judged to be breaking out of fire.Judge the generation of fire when control module 2 after, send alarm signal, inform the generation of refrigerator user fire, in time carry out proper process to warning device 3 (like the high-decibel buzzer etc.).Control module 2 also can cut off the refrigerator power supply automatically after judging that fire takes place, to stop the work of compressor 202, triple valve 203 etc., prevent bigger disaster.In addition, can also have fire alarm disengage button 4 on the electric refrigerator housing body, under the situation that wrong report takes place, press this button and can remove wrong report, make refrigerator get into normal mode of operation.

In addition, in the present embodiment, also can only adopt hydrocarbon coolant leakage detection probe as detection probe, 5 pairs of hydrocarbon coolant leakage concentration of said hydrocarbon coolant leakage detection probe constantly detect in real time, and constantly send testing result to control module 2.When hydrocarbon coolant leakage concentration surpassed predetermined value, said control module 2 was judged to be fire and takes place, and sent alarm signal to warning device 3 (like the high-decibel buzzer etc.).In addition, in the present embodiment, also can adopt other flammable coolant leakage detection probe, flammable coolant leakage concentration is detected the refrigerator that adopts other flammable refrigerants.

According to the 3rd embodiment of the present invention, platform has fire sensitive parameter detection probe 1 to refrigerator involved in the present invention on the top, in the Machine Room, has hydrocarbon coolant leakage detection probe 5.Two detection probe constantly detect simultaneously in real time, and constantly send testing result to control module 2, carry out the judgement of fire by control module 2.When 2 pairs of wherein a kind of signal determinings of control module are unusual, then send alarm signal to warning device 3 (like the high-decibel buzzer etc.) immediately, inform the generation of refrigerator user fire, in time carry out proper process.Control module 2 also can cut off the refrigerator power supply automatically after judging that fire takes place, to stop the work of compressor, triple valve etc., prevent bigger disaster.In addition, can also have fire alarm disengage button 4 on the electric refrigerator housing body, under the situation that wrong report takes place, press this button and can remove wrong report, make refrigerator get into normal mode of operation.

Introduce the automatic fire alarm method of refrigerator involved in the present invention below.As shown in Figure 4, S1 is detected at 1 pair of refrigerator fire-prone of detection probe position in real time, converts the detection signal of this detection probe 1 into analog signal S2; And then this analog signal is sent to control module S3, control module 2 takes a decision as to whether fire S4 takes place, if the result is not for; Then return step S1, if the result is for being, then control module 2 sends alarm signal S5 to warning device 3; Warning device 3 sends fire alarm signal S6, and people receive the report for police service behind the signal, judge whether S7 really takes place fire; If, then handle fire S8, if not; Then be judged as fire false alarm S9, remove warning S10 through fire alarm disengage button 4, and return step S1.In addition, among the step S5, control module 2 also can be after judging that fire takes place; Automatically cut off the refrigerator power supply; Afterwards, if in step S7, be judged to be false alarm, can be through making refrigerator recover normal mode of operation in the 4 releasing warnings of fire alarm disengage button in step S10.

Though more than combine accompanying drawing and embodiment that the present invention is specified, be appreciated that above-mentioned explanation does not limit the present invention in any form.Those skilled in the art can be out of shape and change the present invention as required under the situation that does not depart from connotation of the present invention and scope, and these distortion and variation all fall in the scope of the present invention.
