Problems solved by technology

However, this device cannot solve the phenomenon that the alarm action of the dishwasher is ineffective when the whole machine is slightly inclined. When the dishwasher of this device is in an inclined state, since the overflow of the bottom plate will flow out along the edge of the bottom plate, the liquid level of the bottom plate will The height changes greatly, which makes the float unable to float to a certain height and touch the alarm switch

Abstract

The invention relates to an overflow protection device of a dish washing machine and the dish washing machine. The overflow protection device comprises an overflow base plate, a cross beam connected with the overflow base plate and an overflow receiving groove formed in the cross beam, wherein a supporting part provided with an accommodating space is arranged on the overflow base plate, the accommodating space of the supporting part is communicated with the overflow receiving groove, and an overflow floater changing with the overflow base plate and height of the liquid level in the supporting part is arranged in the supporting part. The overflow floater in the overflow protection device is provided with two contact faces, one contact face is in contact with the liquid level in the supporting part, the other contact face is in contact with the liquid level in the overflow base plate. When overflow water of the dish washing machine overflows from an overflow port of an inner container or flows into the overflow base plate from other positions, a warning device can be triggered, the dish washing machine can also normally give an alarm due to the size of the supporting part is small when the whole dish washing machine is in an oblique state, and accordingly the overflow protection performance of the dish washing machine is improved.

Description

technical field [0001] The invention relates to a water overflow protection structure, in particular to a water overflow protection device for a dishwasher and the dishwasher. Background technique [0002] The dishwasher overflow protection system plays an important role in protecting the dishwasher from overflow, water seepage, water leakage and other faults.
