Description

Filtering device of dish washing machine

Technical Field

The utility model relates to the technical field of dish washing machines, in particular to a filtering device of a dish washing machine.

Background

With the increasing development of science and technology and the improvement of living standard, especially with the rapid development of household appliance technology, a special dish washing device is provided for the aspect of tableware cleaning. A multifunctional dish washing machine generally has the functions of spraying, drying, sterilizing and the like, a user only needs to put tableware such as bowls and chopsticks into the dish washing machine, the dish washing machine can automatically complete a series of cleaning works according to the setting of the user, the use is convenient, the automation is full, the operation of the user is effectively reduced, and the dish washing machine is more and more loved by general users.

The dishwashers of the prior art are generally provided with a filter device for filtering the contaminants in the water, which filter device comprises at least one coarse filter and one fine filter. Wherein, the coarse filter is used for filtering larger particles in the pollutants; microfilters are used to filter smaller particles from contaminants. Although the coarse filter can filter larger particles, the following technical defects still exist:

1. the structure limitation causes the production mould to be too complex and the production cost to be higher. As shown in fig. 1 to 3, the coarse filter of the prior art is generally provided with water through holes on the peripheral side, and the water through holes are arranged at intervals in the vertical direction. For the machining and forming of the coarse filter with the structure, the production die of the coarse filter can be combined and machined and formed by four directional dies with an upper die, a lower die, a left die and a right die. Therefore, the coarse filter with such a structure is complicated, and the cost for producing the mold is high.

2. And is easy to block. As shown in figures 1 to 2, when the pollutant of bigger granule upwards piles up in the cup gradually, because the water hole of crossing on the coarse filter week side is that the interval of upper and lower direction sets up, therefore the unable vertical intercommunication in water hole leads to the water level in the coarse filter can't in time discharge when being in the spaced position, influences the filter effect.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a filter equipment of dish washer solves the complicated mould of structure of prior art coarse filter problem with high costs and the filter effect is poor, improves the filter equipment structure of dish washer, can simplify the structure in order to reduce the mould cost, can improve the filter effect again effectively.

In order to realize the purpose, the utility model discloses a technical scheme is:

a filtering device of a dish washing machine comprises a coarse filter, wherein the coarse filter is of a cup body structure with an opening at the top, a plurality of water passing grooves are formed in the peripheral wall of the coarse filter, and the water passing grooves are annularly arranged along the peripheral wall of the coarse filter at intervals; each water passing groove extends from the bottom of the peripheral wall of the coarse filter to the top of the peripheral wall to form a water passing channel longitudinally penetrating through the wall surface of the peripheral wall of the coarse filter.

The utility model discloses filter equipment of dish washer compares with prior art, and is very right coarse filter's structure is improved, and coarse filter's perisporium is equipped with a plurality of water channels of crossing, and crosses water channel along coarse filter's perisporium hoop and interval arrangement, has simplified coarse filter's shape for the production mould only needs the cooperation of mould and lower mould, just can realize this coarse filter's production, reduces the mould cost effectively.
