Electromagnetic lock for cleaning machine

Abstract

The invention discloses an electromagnetic lock for a cleaning machine. The electromagnetic lock includes an electromagnetic lock body and a lock rod which can stretch and retract relating to the electromagnetic lock, and also including a positioning member arranged on one side of the electromagnetic lock body and tightly fit with the electromagnetic lock body, and a first leather cup and a second leather cup for sealing, wherein a cavity with two open ends is formed in the positioning member; the lock rod passes through the positioning member; two ends of the first leather cup are respectively fixed with the periphery of the first end, away from the electromagnetic lock body, of each of the lock rod and the cavity, and seal the first ends; two ends of the second leather cup are respectively fixed with the periphery of the second end, close to the electromagnetic lock body, of each of the lock rod and the cavity, and seal the second ends. Through the arrangement of the two leather cups, the effect of dual sealing is provided, water and steam can be effectively blocked at the outer side of the electromagnetic lock body, in addition, residues after cleaning and dirt also can be blocked at the outer side of the electromagnetic lock body, and thereby the normal work and service life of the electromagnetic lock are ensured.

Description

technical field [0001] The invention relates to an electromagnetic lock, in particular to an electromagnetic lock used for a washing machine. Background technique [0002] A dishwasher is a device that sprays cold or hot water onto dishes to remove dirt adhering to the dishes and to clean the dishes. The dishes are placed in the dish frame in the dishwashing cabinet. A general dishwasher includes a pump for spraying washing water, a nozzle, and a heater for generating hot water. Today's dishwashers have begun to use steam to clean dishes. Compared with using heated water, using steam also reduces the washing time and improves the washing effect. However, when this kind of dishwasher is cleaning dishes, the water in the machine not only has a higher temperature but also is accompanied by the generation of water vapor. In this case, if the dishwasher door is suddenly opened without resistance, the temperature will Higher water and water vapor will splash or overflow, and the...

Problems solved by technology

[0005] However, since the washing machine will generate water vapor in the washing space when the dishes are cleaned, and the washing space during work is a closed cavity, this will greatly increase the pressure in the washing space, resulting in water vapor under pressure. Driven by the electromagnetic lock, it is possible to enter the electromagnetic lock through the sealing ring between the electromagnetic lock and the sink body

In addition, when the washing machine is cleaning dishes or fruits and vegetables, the residue or sludge falling from the dishes or fruits and vegetables will enter the electromagnetic lock through the gap of the lock rod of the electromagnetic lock due to the centrifugal effect of the rotating spray arm. , which will increase the possibility of failure of the electromagnetic lock, and may also reduce the service life of the electromagnetic lock
