Description

Cleaning machine

Technical Field

The utility model relates to the technical field of household appliances, in particular to a cleaning machine.

Background

In the existing cleaning machine, in order to avoid the water level in the cleaning cavity overflowing to a cabinet outside the cleaning machine, an overflow channel is arranged at the bottom of the cleaning cavity, when water is caused to increase and cannot be discharged in time when the machine fails, the increased water can be discharged to a bottom plate of the base through the overflow channel to trigger a water leakage switch, so that the machine can alarm to stop working, and water flow in the cleaning machine is prevented from leaking.

Although the existing overflow port can play a role in guiding redundant water inflow to warn, because the overflow port is in a normally open state, water vapor can enter the base cavity through the overflow port in other using stages such as drying, so that the fault of an electric device in the base cavity can be caused, and the electric device is required to be subjected to independent water vapor protection treatment, so that the production cost is increased.

Therefore, the applicant's prior application discloses a washer, whose patent number is CN202123140178.0, in which an air inlet and an air outlet are provided on a side wall of a water collecting cavity, and a fan for driving air flow to be sucked into the water collecting cavity from the air inlet and discharged from the air outlet is provided, so that convection of air flow in the overflow protection device can be improved, and evaporation rate of overflow in the overflow protection device can be improved.

Although the above-described washer improves the evaporation rate of the water vapor in the overflow protection device, the subsequent measures only after the water vapor or the overflow is discharged cannot effectively suppress or avoid the entry of the water vapor, and thus further improvement is required.
