The embodiments will be further described with reference to the accompanying drawings for the realization of the utility model function and advantage.

Specific embodiment

The utility model is described in further detail with preferred embodiment with reference to the accompanying drawing.

As shown in Figures 1 to 4, the overflow alarm structure of a kind of internal cavity of bowl washer, the overflow alarm of the internal cavity of bowl washer Structure includes dish-washing machine bottom cover 1 and the spilling water inductor 2 being electrically connected on bottom cover 1 with the machine control system that washes the dishes, the bottom cover 1 Detent 11 is equipped at paracentral position, the spilling water inductor 2 is connected in the detent 11, and the two of spilling water inductor 2 A induction electrode 21 is contacted with the upper surface of bottom cover 1, when thering is water to leak into bottom cover 1 in internal cavity of bowl washer, the two of spilling water inductor 2 Resistance between induction electrode 21 becomes smaller, and control system detects whether the resistance variations between two induction electrodes 21 determine liner Leak, and make corresponding judgement.

Preferably, spilling water inductor 2 is equipped with the buckle 22 being adapted to detent 11, and spilling water inductor 2 passes through 22 card of buckle In in the detent 11；When assembling spilling water inductor 2, the buckle 22 of spilling water inductor 2 can directly be snapped fit onto the card of pedestal On position 11, convenient for operation.

Preferably, buckle 22 is equipped with locating slot 221, and the detent 11 is equipped with the locating piece being adapted to locating slot 221 111；When buckle 22 snaps fit onto detent 11, locating piece 111 is protruded into card slot；It can make spilling water inductor 2 and detent 11 Connect it is stronger, avoid spilling water inductor 2 loosen, make induction electrode 21 and 1 poor contact of bottom cover, influence control system make it is excessive Stream or leak early warning.

Preferably, several ring-shaped splash guards 12 for being upwardly extended and being formed by base upper surface are arranged concentrically on bottom cover 1, often Region between a water fender 12 and the water fender 12 of its inner ring, which is constituted, divides pool 13, is evenly equipped on each water fender 12 Several spilling water grooves 121；The interior plate of dish-washing machine is equipped with overflow hole, and when liner water level is excessively high, the water in liner is through overflowing Discharge orifice flows into bottom cover 1, and enters outmost turns on bottom cover 1 at first and divide pool 13, and when spilling water is seldom, the water for overflowing into bottom cover 1 is complete Portion is remained in the region that outmost turns are made of 1 periphery of bottom cover；Spilling water inductor 2 can't detect spilling water at this time；Only when The water that liner overflows diffuses in point pool 13 closed on through the spilling water groove 121 on outer ring water fender 12, and enters lid 1 on earth When center position, spilling water inductor 2 can just occur curent change and then be arrived by control system monitoring, and control system will at this time Issue leak early warning；Washing Intermediate switch door can cause liner at the bottom SEA LEVEL VARIATION, and it is made to flow into bottom cover 1 through overflow hole；Such as Fruit slightly water overflow, which enters bottom cover 1, will excite control system, not meet practical application；The setting of bottom cover 1 divides pool 13, only liner When interior dilutional hyponatremia overflows, just control system issues spilling water early warning when meeting；More meet practical application；If but when sink leak, from The water that sink leaks down will fall directly on point pool 13 at 1 center of bottom cover and be detected by spilling water inductor；Control system at this time Leak early warning will be immediately issued, avoids leak excessive, the electric elements for being installed on liner at the bottom is caused bad.

Preferably, point pool 13 that the water fender 12 that detent 11 is set at base center surrounds, both can have one to spilling water Fixed tolerance level, leak can be sensed in time by having.

Preferably, pedestal is equipped with the reinforcing rib 14 through each point of pool 13；The intensity of pedestal can be increased.

Preferably, water fender 12 is located at least one spilling water groove 121 on the part between two reinforcing ribs 14；Reinforce Muscle 14 divides pool 13 through a, each point of pool 13 is divided into 13 domain of several small point of pool again, only on each small point of pool 13 has Overflow groove is set, and the water of spilling could circulate in adjacent 13 domain of small point of pool.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Made any modification, equivalent replacement or improvement etc., should be included in the utility model within the spirit and principle of utility model Protection scope within.
