Description

Sealing structure of dish washing machine and dish washing machine

Technical Field

The utility model relates to a dish washer field, in particular to seal structure and dish washer of dish washer.

Background

Along with the improvement of people's standard of living, the dish washer trade has developed rapidly, for satisfying various consumer's demand, also constantly make optimization and innovation to the function and the structure of dish washer in the trade, in daily life, the most basic function of dish washer is to wash the tableware, its theory of operation is exactly through heat exchange system and water circulating system's cooperation and spray the washing that realizes the tableware through the high pressure of spraying system, so dish washer is in the work process supplementary of leaving no water, consequently need set up seal structure between the door body of dish washer and the inner bag of dish washer, in order to prevent that the high-pressure rivers that dish washer spraying system jetted from spilling over outside the dish washer at the work process.

The traditional dish-washing machine is generally of a side-opening door structure, the sealing element is arranged at the opening on the side surface of the inner container and the sealing element is arranged on the door body to realize the sealing between the inner container and the door body, however, a gap is easily generated between the sealing piece arranged at the opening at the side surface of the inner container and the sealing piece arranged on the door body, water in the inner container can seep out from the gap during the operation of the dishwasher, thereby flowing to the electric elements at the bottom of the dish-washing machine to cause potential safety hazard, and after the dish-washing machine is used for a long time, the sealing part is easy to accumulate water stains and breed bacteria between the sealing piece and the inner container and between the sealing piece and the door body due to long-term contact with water for washing tableware, and the sealing piece is easy to deform after long-term use, so that the sealing property is reduced, however, the above-mentioned sealing element is complicated in mounting structure and is not easy to mount and dismount, thereby increasing the difficulty in cleaning and maintenance.

SUMMERY OF THE UTILITY MODEL

The utility model discloses aim at solving one of the technical problem that exists among the prior art at least. Therefore, the utility model provides a sealing structure of dish washer convenient to wash and be convenient for maintain and change.

The utility model also provides a dish washer of seal structure with above-mentioned dish washer.

According to the utility model discloses a seal structure of dish washer of first aspect embodiment includes:

the shell is of a cavity structure with an opening at the top;

the upper cover is rotatably arranged at the opening at the top of the shell;

the inner container is of a cavity structure with an opening at the top, is arranged in the shell, and is provided with a mounting groove at the upper part of the outer side wall;

the sealing ring comprises an insertion end and a stretching end, the insertion end is arranged in the mounting groove and is tightly matched with the mounting groove, and a butt joint structure capable of being abutted against the inner side of the stretching end and being tightly matched with the stretching end is arranged on one side, facing the opening in the top of the inner container, of the upper cover.

According to the utility model discloses seal structure of dish washer has following beneficial effect at least: because the inner bag is open-top's cavity structures, has consequently avoided the condition that the seal structure of dish washer can the water of continuous contact washing tableware in the washing process, the upper portion of the lateral wall of inner bag is provided with and is used for the installation the mounting groove of sealing washer, through with place in the insertion end of sealing washer in the mounting groove and with the mounting groove tight fit, in order to realize the installation of sealing washer, through the upper cover compress tightly in the end that stretches out of sealing washer, simultaneously, butt structure butt in stretch out the inboard of end and with stretch out the end tight fit to reach sealed purpose, its simple structure, be convenient for installation and dismantlement can reduce under the prerequisite of guaranteeing sealed effect the degree of difficulty of sealing washer when wasing and maintenance when changing.

According to the utility model discloses a some embodiments, the upper portion of the lateral wall of inner bag transversely is equipped with first hem outwards, first hem is kept away from one side of the lateral wall of inner bag is equipped with the second hem up, the lateral wall of inner bag first hem and the second hem encloses the mounting groove. The structure is simple, the realization is easy, and the cost of production and processing is reduced.

According to some embodiments of the present invention, the insertion end is provided with a pawl. Can increase insert the end with frictional force between the mounting groove to prevent the sealing washer is not hard up or scurries at dishwasher course the mounting groove is favorable to improving the stability of sealing washer in dishwasher course, thereby has guaranteed sealing performance.
