Description

Overflow rod and dish-washing machine

Technical Field

The utility model belongs to the technical field of dish washers, and particularly relates to an overflow rod and a dish washer.

Background

And the overflow rod is used for being inserted into the water outlet hole at the bottom of the water tank of the dish-washing machine to block the water outlet hole. When the bowl is washed, the overflow rod is pulled out when water is needed to be drained, water can flow out from the water outlet hole, and meanwhile the water level in the water tank is prevented from being too high to flow out to pollute the washing space. There are two main types of overflow bars for dishwashers (especially commercial dishwashers) currently on the market: the first is that the whole structure is made of all plastic; the second is that the whole structure is all metal.

The overflow rod with the all-plastic structure has the problems of easy corrosion and easy breakage. Meanwhile, the all-plastic overflow rod is inserted into the water outlet hole at the bottom of the water tank of the dish washing machine, when water is needed to be drained after dishes are washed, the overflow rod is pulled out, water can flow out from the water outlet hole, and when the dish washing machine is in actual use, an operator usually pulls out the overflow rod not directly upwards and downwards, usually pulls out the overflow rod obliquely, so that the bottom end of the overflow rod is easily broken at the water outlet hole and is difficult to take out; the overflow rod with the all-metal structure is corrosion-resistant and cannot be broken, but the water outlet hole at the bottom of the water tank of the dish washer can be pried and deformed in the operation process (repeated insertion and extraction), so that water leakage and other serious problems are caused.
