Dishwasher

Abstract

The invention relates to a dishwasher comprising a water cup, a drainage system, and a rinse system and a circulation filter system, which are communicated with the water cup, wherein a rinse pump chamber and a circulation pump chamber, which are independent from each other, are arranged in the dishwasher, a rinse pump is arranged in the rinse pump chamber, a filtration device is arranged on the water cup, the water inlet of the rinse pump chamber is communicated with the water cup, and the water outlet is connected with a sprinkling device of the rinse system; and a circulation pump is arranged in the circulation pump chamber, the water inlet of the circulation pump chamber is communicated with the water cup, a filter screen and slag cuter blades are arranged at the water inlet, the water outlet of the circulation pump chamber is communicated with a circulation filter chamber, the upper part of the circulation filter chamber is provided with a circulation filter screen, and the lower part of the circulation filter chamber is provided with a slag discharge opening communicated with a drainage system. The dishwasher of the invention uses the independent circulation pump to provide water for a circulation filter, so that food residues can be filtered, circulation water and tableware can be prevented from suffering secondary pollution, and the flow rate and the hydraulic pressure of rinsing water can not be weakened; and therefore the cleaning efficiency of the dishwasher is increased, and water and energy consumption is reduced.

Description

technical field [0001] The invention relates to the internal structure of a dishwasher, in particular to the modification technology of the circulation filter system of the dishwasher. Background technique [0002] Currently, the dishwasher adopts a circulating filter system to filter, and its circulating filter system includes a debris blade 4 , a filter screen 5 , a washing pump 2 , a circulating filter chamber 8 with a circulating filter screen 7 , and a motor 3 . as attached figure 1 As shown, its working process is as follows: the circulating washing water inside the dishwasher flows into the water cup 1 at the bottom of the dishwasher liner with food residues, and flows to the water inlet of the washing pump cavity 6 under the suction of the washing pump 2 . The water inlet of the washing pump chamber 6 has a debris blade 4 installed on the shaft of the washing pump motor 3, and there is one deck filter screen 5 between the debris blade 4 and the washing pump impelle...

AI Technical Summary

Problems solved by technology

Therefore this circulating filtration system has the following disadvantages: (1), most of the fine food residues that are broken into pieces directly enter the washing cycle, and pollute the tableware inside the dishwasher again. Good filtering effect, so water consuming, time consuming, energy consuming

(2) Small food residues that directly enter the washing cycle can easily block the spray arm holes and affect the normal operation of the dishwasher

(3) It is necessary to divide part of the water from the washing circulating water into the circulating filter to participate in the filtration, resulting in a small amount of hydraulic water entering the spray arm, and at the same time, the water consumption increases, which affects the scouring force and scouring effect of water on tableware

(4) Water will be contained in the pressure relief pipe of the circulating filter chamber, which will increase water consumption; at the same time, viscous grease and other pollutants will adhere to the inner wall of the pressure relief pipe of the circulating filter chamber, which cannot be cleaned
