Description

Integrated dishwasher water metering

technical field

The utility model relates to a dishwasher, in particular to a water inlet metering device for the dishwasher.

Background technique

With the continuous improvement of people's living standards, fully automatic dishwashers have gradually become a household appliance commonly used in people's daily life. A fully automatic dishwasher is a machine that washes, rinses and dries tableware by chemical, mechanical and thermal means. The fully automatic dishwasher is driven by a motor to wash the pump, and the water flow with strong injection pressure is formed through the washing pump. The water flow can be strongly sprayed out from the hole of the spray arm. Water is evenly and densely sprayed onto the surface of tableware from three-dimensional directions with a certain pressure for strong washing; hot water soaks and expands food residues; detergent emulsifies and decomposes oil and residues and sterilizes them. This three-pronged power of force, heat and chemical action makes the oil stains and residues on the surface of the tableware quickly decompose and fall off; then the tableware is rinsed strongly with clean water; finally, the tableware is dried with high-temperature waste heat.

With the market's increasing requirements for product performance, manufacturers of various dishwashers are constantly striving for the largest market share by improving the technical level of their products and reducing product costs. The current fully automatic household dishwashers sold on the market, the water inlet device and the water inlet metering device are controlled by two separate devices during work. The disadvantages of using this structure are: complex structure, bulky, difficult to install Inconvenient, low production efficiency, higher production costs.
