Above-mentioned valve with take out pump and will be connected in parallel, be provided with as constraint to the triac of above-mentioned valve at above-mentioned valve and each front end of taking out pump with the switching device of taking out the power supply that pump supplies with.On electric connection mode, above-mentioned valve with take out pump will be respectively and being connected in series of above-mentioned triac.
Promptly; The above-mentioned second cut-out portion can be made up of fast molten little electric current fuse; It is at above-mentioned valve or when taking out the insulation breakdown of reduced-capacity load such as pump, with detecting the overcurrent that flows on the above-mentioned triac, and open circuit rapidly; Thereby can prevent above-mentioned valve or take out the electric injury of pump, and can prevent to be used to control the heating of the circuit part of above-mentioned triac.Thus; Limiting value is installed in the reduced-capacity load of the electric current of the usual 1 ~ 1.5A of consumption is under the situation of fuse of the above-mentioned second cut-out portion of conduct of 3A; When above-mentioned reduced-capacity load (consumes 5 ~ 6A), with the effect of playing the protection reduced-capacity load during with 20 Ω short circuits approximately on circuit.
Fig. 4 is the block diagram that illustrates the overcurrent cutting-off device of the device for clothing processing in another embodiment of the present invention.
As shown in Figure 4; In the overcurrent cutting-off device 400 of the device for clothing processing of another embodiment of the present invention; Be provided with the big capacity load and the reduced-capacity load of connection parallel with one another in the device for clothing processing, it includes with lower component: the display part 490 that is used for display message; The first cut-out portion 420 of the above-mentioned big capacity load of protection from the improper electric current that flows into to load-side; The second cut-out portion 450 of the above-mentioned reduced-capacity load of protection from the improper electric current that flows in load-side; Detect the status detection portion 480 of above-mentioned first and second cut-out portion; According to the state of above-mentioned detected cut-out portion, control the control part 470 that above-mentioned display part 490 shows dissengaged positionss.
Identical among the process that above-mentioned first and second cut-out portion 420,450 cuts off when improper electric current flows into and the above-mentioned embodiment; In order not obscure the major technique thought of present embodiment, below will save the function of above-mentioned first and second cut-out portion 420,450 and the explanation of driving.
Power supply will be cut off when abnormal current flows into, and still, which cut-out portion the user can't learn in, and rupturing operation takes place, and just learn because of inflow has improper electric current and cut off the supply of power supply in order to protect load.
Above-mentioned test section 480 is with periodic or under the situation that certain situation takes place, and with the curtage of first and second cut-out portion of detection etc., thereby detects the driving condition of current cut-out portion.When above-mentioned test section 480 detects the dump that the inflow etc. of improper electric current causes, above-mentioned control part 470 will show the current position that is in the cut-out portion that cuts off driving condition to the outside through above-mentioned display part 490.
Thus, user or manager be in the inflow of improper electric current and during the breakdown maintenance of the washing machine that causes, can confirm the position that cuts off rapidly, thereby the convenience in the use is provided.
Above with reference to embodiment among the present invention and accompanying drawing; And use roller washing machine to carry out detailed explanation as example with washing/oven dry; But the present invention is equally applicable to multiple washing machine, dryer etc.; And scope of the present invention is not to be defined in above embodiment and accompanying drawing, and scope of the present invention will be limited the content of putting down in writing in the appending claims.
