AI Technical Summary

Technical Problem

In existing dishwashers, there is a gap between the waste hot water tank and the lid, which causes the main wash circulating water to seep into the waste hot water tank, resulting in heat waste and water waste.

Method used

Design a sealing cover, including a cover body, a sealing ring, and a protrusion. The sealing ring fits tightly against the inner wall of the waste hot water tank to form a tight structure, preventing the main washing circulating water from seeping into the waste hot water tank. A leakage hole and a sealing element are set in the annular groove to ensure effective water discharge.

Benefits of technology

This effectively prevents the main wash circulating water from flowing out of the waste hot water tank, ensuring heat recovery efficiency, saving water resources and energy, and improving the heat recovery efficiency of the dishwasher.

Abstract

This utility model provides a sealing cover, a dual-tank heat exchange water tank, and a dishwasher, belonging to the technical field of dishwasher equipment. The sealing cover includes a cover body and a sealing ring; the cover body has a protrusion with a receiving groove inside, and a bent portion extends from the outside of the protrusion; the shape of the sealing ring is adapted to the receiving groove, and the sealing ring is snapped into the receiving groove; wherein, a receiving gap is formed between the bent portion and the sealing ring, the upper edge of the waste hot water tank is located within the receiving gap, and the inner wall of the waste hot water tank is in contact with the sealing ring. By the inner wall of the waste hot water tank being in contact with the sealing ring, the interior of the waste hot water tank is isolated from the exterior of the cover body. When the main wash circulating water cannot return to the main wash water tank in time and accumulates at a high water level above the sealing cover, submerging the sealing cover, it can effectively prevent high-temperature main wash circulating water from seeping into the waste hot water tank from the gap between the cover body and the waste hot water tank, thereby preventing the main wash circulating water from flowing out of the waste hot water tank and ensuring that the main wash water tank has sufficient circulating water for washing dishes.
