The cleaning method of the application has the following advantages:
(1) Noise advantage
The existing dish washing machine sprays and washes up and down all the time, the water consumption of the upper layer and the lower layer is not adjustable, and the noise in the washing process is an integral dynamic process. The noise source in the dish washer is firstly vibration of the motor during washing, and secondly direct noise generated by spraying and sputtering of the water column on the surfaces of the tableware and the washing cavity during washing. The direct noise generated by spray sputtering of the water column on the surfaces of the tableware and the washing cavity is a main source of noise in the washing process, and when judging that the pollutant is washed only by the lower-layer washing, the lower-layer washing is started in a time sequence, so that the lower-layer washing can be started only, and the noise is much lower than that of the upper-layer washing and the lower-layer washing;
(2) Slag collection advantage (cleanliness aspect)
The dish washer of the centrifugal pump type pump system washes and collects slag together in the washing process, namely, the washing and slag collection are a dynamic process, and the slag collection and washing processes are carried out simultaneously because water flow jet is fluctuated, so that the peeled slag on the surface of tableware is difficult to collect into a slag basket, the design requirement on slag sweeping holes of a spray arm is very high, the slag collection effect is poor if the design environment of points is changed or the slag collection effect is poor due to the fact that the slag collection effect is poor. The application has the advantages that the height of the upper limit and the lower limit of the water level is wide (for example, the water inflow is a fixed value, the water level of the upper layer and the lower layer can be lower when the upper layer is opened, and the water level can be higher when the lower layer is singly washed), so that the optimal water amount of the slag collection is not limited by the optimal water amount (water inflow) of the washing, and the water amount matching advantage of the slag collection is larger;
(3) Water consumption advantage
The total water consumption of the centrifugal pump system which is sprayed all the time in the water return process is composed of the water quantity in the air, the water quantity in the water return cavity and the water quantity stained in tableware. The water quantity of the backflow is the water quantity occupying most part, the variable washing water supply is provided with a judging process, and the water quantity is less, so that the water inflow is less and the water consumption is reduced when the water quantity is judged to be less although the number of the washing sets is the same;
(4) Energy consumption advantage
Because the water consumption is lower, the energy consumption required for heating the washing water to the same temperature is much lower;
(5) Wash advantage
The intermittent change of the up-and-down flow of the application makes the spray water column similar to pulse washing, and is beneficial to improving the cleaning effect by starting the upper-layer and lower-layer spray (removing secondary pollution) or starting single-layer washing (main cleaning) at any time in the cleaning process.
In the description and claims of the present application, terms indicating directions, such as "front", "rear", "upper", "lower", "left", "right", "side", "top", "bottom", etc., are used to describe various example structural parts and elements of the present application, but these terms are used herein for convenience of description only and are determined based on the example orientations shown in the drawings. Because the disclosed embodiments of the application may be arranged in a variety of orientations, the directional terminology is used for purposes of illustration and is in no way limiting, such as "upper" and "lower" are not necessarily limited to being in a direction opposite or coincident with the direction of gravity.
