Cleaning machine

Technical Field

The utility model relates to the technical field of kitchen household appliances, in particular to a cleaning machine for cleaning tableware, vegetables or fruits.

Background

A dishwasher is an apparatus that sprays cold or hot water to a dish to remove dirt adhered to the dish and wash the dish. The dishwasher on the market mainly comprises a table type dishwasher, a cabinet type dishwasher and a tank type dishwasher, wherein the tank type dishwasher is combined with a water tank and is generally installed in a kitchen cabinet for use. In order to save space, a number of sink-type washing machine designs have emerged, i.e. the existing sink is retrofitted to a washing machine for washing dishes, fruits, vegetables, etc., directly with the sink as the washing space.

In order to accelerate the drying of washed tableware, fruits and vegetables so as to prevent the breeding of bacteria, a drying device for drying a washing space is arranged on the existing water tank type dish washing machine. For example, chinese patent application No. CN201910169694.4 (publication No. CN111657810A) discloses a cleaning machine, which includes a water tank body having a washing chamber, and is characterized in that: the detachable draining plate is arranged in the water tank body and can enable the upper space and the lower space of the washing cavity to be relatively independently arranged, and a water draining hole for water on the draining plate to flow into the lower space from the upper space is formed in the draining plate; the edge of the draining plate is provided with a vertically arranged surrounding edge, a first air inlet is formed in the surrounding edge which is opposite to the lower water hole, a second air inlet is correspondingly formed in the water tank body, and a blowing device which can enable air outside the water tank body to pass through the second air inlet and the first air inlet and flow through the draining plate is arranged outside the water tank body; the bottom of basin body is provided with the heating plate that can heat this internal water of basin, blast apparatus still includes the wind-guiding structure that can utilize the heat of heating plate to carry out the heating to the wind that gets into this internal water of basin.

The cleaning machine can dry the space above the draining board and the draining board by arranging the air blowing device to convey heated air into the water tank body, so that the drying speed of fruits, vegetables or dishes on the draining board is increased. However, since the drying procedure inside the cleaning machine is performed after the cleaning procedure is finished, and the power of the heating plate is high, the utilization rate of heat generated by the heating plate is low no matter in the cleaning procedure or the drying procedure, so that not only is the energy consumption high, but also local overheating of the heating plate is caused, the heating plate is easy to damage, and the temperature rise at the bottom of the cleaning machine is high. In addition, because the separation of draining board, the lower part space of washing chamber can't reach the purpose of drying during the air convection, can gather on the inner wall of the basin body of draining board after a large amount of vapor condensation, breed the bacterium easily.
