Abstract
The utility model relates to a water overflow protecting device for a washing machine, comprising a water pan, a float and a microswitch, wherein, the water pan is arranged on the bottom case of the washing machine and communicated with the outer cavity of the washing machine; the float is arranged in the water pan, the microswitch is positioned above the float, and the top of the float is provided with a bulge touching the microswitch. Upon water leakage or overflow caused by washing machine failures, water can flow along the bottom board of the washing machine or a guide groove of a bottom reinforcing element down to the water pan, the float moves upward under the action of buoyancy to push the microswitch to switch off a water feeding electromagnetic valve circuit and switch on a drain motor circuit and an alarm device circuit, so that phenomena of endless water-in can be avoided, water in a barrel can be discharged in time, and users can be reminded of taking measures in time.
Description
The utility model belongs to the protective device of washing machine spilling water under non-normal condition.
Domestic washing machine did not have spilling water protection warning device as yet before the utility model was made; when faults such as appearance such as bucket in the washing machine leaks, pressure switch is malfunctioning; it is more than to intake: owing to effectively do not protect warning device; often can not in time find; the lighter's electric resources of wasting water; weight person is soaked other family's property that damages the user, causes damage.
For addressing the above problem, the utility model provides a kind of washing machine that utilizes to overflow the buoyancy of water touch switch, starts draining pump, cuts off the washing machine spilling water protective device of water intaking valve power supply.
For achieving the above object, the utility model is a kind of use in washing machine spilling water protective device of realizing like this, and this device comprises drip tray, and float and microswitch are used support and fixture fixedly drip tray and microswitch; Drip tray places washing machine drain pan and washing machine exocoel to communicate; Float places in the drip tray and with the drip tray shape and adapts, microswitch is positioned at the float top, the projection of touching mutually with microswitch is arranged at the float top, touches the microswitch that cuts off washing machine inflow device power supply and/or touches the microswitch of connecting the drainage arrangement power supply.
The circuit that this protective device is controlled is entering water electromagnetic valve and the series connection of program controller equivalent switch, connects power supply by normally closed microswitch; Often drive the draining pump of connecting behind the microswitch program controller equivalent switch in parallel, foregoing circuit connects both ends of power.
The required maximum force of above-mentioned microswitch is less than 30 grams.
The shape of the float of described washing machine spilling water protective device is square or circular, and the float bottom area is greater than the top.
Advantage of the present utility model and good effect are: under the washing machine normal condition, the protection warning device does not influence the work of washing machine; Cause and leak or during spilling water when washing machine breaks down, water will flow to the drip tray place along the guiding gutter of washing machine base plate or following reinforcement, float moves upward under buoyancy function, promote microswitch, make it to disconnect the entering water electromagnetic valve loop, connect drain motor loop and warning device loop, so just can prevent the into more than phenomenon of water, simultaneously the water in the bucket is in time discharged, and the alert notice user in time take measures.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the front view of the structural representation of a utility model and an embodiment;
Fig. 2 is the vertical view of the structural representation of an embodiment of the utility model;
Fig. 3 is the circuit connection diagram of an embodiment of the utility model.
As shown in Figure 1, 2.A kind of this device of washing machine spilling water protective device comprises drip tray 2, and float 1 and microswitch 3,4 are used support and fixture 10 fixedly drip tray and microswitch; The whole protecting device can be installed on washing machine base plate, following reinforcement base plate or the following reinforcement.Should go out the drip tray and the guiding gutter 11 that are used to connect spilling water in advance; Float is made present embodiment by the minimum material of density and is adopted foamed plastics to make, and the bottom is square or circular, and area is bigger; Microswitch is for improving detection sensitivity, and the switch maximum force is chosen in below the 30g.Supporting adn fixing device is plastic products, and the bottom is the annular of band hook, be used for self being fixed on the washing machine base plate or strengthening reinforcement down, and the range of movement of protection restriction float; The middle part is a side plate 12, and the erection column on the plate is used to install microswitch; The top is a cover plate 13, and the protection microswitch also prevents that microswitch from directly being drenched by water.Drip tray places washing machine drain pan and washing machine exocoel to communicate; Float places in the drip tray and adapts with the drip tray shape, makes drip tray play the effect of automatic location and guiding to float, makes float avoid can not touching microswitch because of moving around.Microswitch is positioned at the float top, and the projection 5 of touching mutually with microswitch is arranged at the float top, touches the microswitch 3 that cuts off washing machine inflow device power supply and touches the microswitch 4 of connecting the drainage arrangement power supply.
The circuit that this protective device is controlled as shown in Figure 3.Program controller equivalent switch 7 series connection entering water electromagnetic valves 6, one ends connect the 220V power firestreak, and the other end is connected with the normal-closed end 3b of normally closed microswitch 3, and the common port 3a of microswitch 3 connects the zero line of 220V power supply.Between the Chang Kaiduan of microswitch 3 3c and 220V power firestreak, connect the buzzer 14 of 220V50HZ in order in use there to be warning device to report to the police.Often open the common port 4a of microswitch 4 and an end of program controller equivalent switch 8 and be connected the 220V power firestreak jointly, the Chang Kaiduan 4c of microswitch 4 and the other end parallel connection of program controller equivalent switch 8, the common zero line that connects power supply by draining pump 9.The normal-closed end 4b of microswitch 4 hangs empty.
Cause and leak or during spilling water when washing machine breaks down, water will along the washing machine base plate or down the guiding gutter of reinforcement flow to the drip tray place, float moves upward under buoyancy function, promotes microswitch.Normally closed microswitch 3 normal-closed end 3b disconnect, and Chang Kaiduan 3c connects and makes the entering water electromagnetic valve loop disconnect buzzer connection simultaneously; The Chang Kaiduan 4c that often drives microswitch 4 connects the drain motor loop is connected.So just can prevent the into more than phenomenon of water, simultaneously the water in the bucket is in time discharged, and the alert notice user in time take measures.
