Description
Technical Field
[0001] The utility model belongs to a commercial dishwasher, in particular to a drainage system of a commercial front-loading dishwasher and a commercial lid-lifting dishwasher. Background Art
[0002] With the improvement of living standards and the increase of the pace of life, more and more people choose to eat in restaurants, so the use of commercial dishwashers is becoming more and more frequent. Fig. 9 , Fig.10 As shown, whether it is a commercial front-loading dishwasher or a commercial lid-type dishwasher, their drainage systems are usually manual drainage systems, which have the following problems: First, manual drainage requires manually opening the machine door and manually pulling out the overflow pipe. The overflow pipe is at the same height as the sewage. When pulling out the overflow pipe, the hand will touch the sewage in the sink, which is very unhygienic. At the same time, there is a risk of infection from contact between the hand, dishwashing sewage, and cleaning plates; Second, the high-level drainage in the washing chamber is through the height of the upper opening of the drain pipe. When the water level reaches higher than the upper level, gravity drainage is used. The drainage speed is slow and the drainage efficiency is low, which affects the normal use and washing effect of the dishwasher; Third, there is usually a drainage ditch in China, and the sewage of the dishwasher can be directly discharged into the ditch, but the drainage ditch abroad is generally 300-400mm above the ground. The drainage system cannot achieve high-level drainage, that is, it cannot discharge sewage into the high-level ditch, so it cannot meet European and American standards and cannot meet the needs of foreign markets.
