AI Technical Summary

Technical Problem

The existing dishwasher pump heater has an unreasonable structural design, which leads to rapid heat loss, affecting the heating effect. The thermostat is also unstable and has a short service life.

Method used

Design a heater for a dishwasher pump with an insulation cover. By setting an insulation cover on the outer end face of the steel plate and leaving a gap between it and the heating tube, and setting a positioning groove and a limiting block at the thermostat position, the thermostat is fixed by welding and bolts to avoid direct metal contact for heat conduction and ensure accurate positioning and fixation of the thermostat.

Benefits of technology

It achieves slow heat dissipation, good heating effect, reliable temperature controller, long service life, and strong practicality.

Abstract

This utility model discloses a heater for a dishwasher pump with a heat insulation cover, comprising a steel disc and a heating tube. A recessed heating tube mounting groove is provided on the outer end face of the steel disc, and the heating tube is installed in the heating tube mounting groove. A temperature control component is partially provided on the heating tube, and the temperature control component includes several temperature controllers. A heat insulation cover is fixedly mounted on the outer end face of the steel disc, and the heat insulation cover is fixedly connected to the steel disc, with the inner wall surface of the heat insulation cover and the outer end face of the steel disc forming a heat insulation cavity. A temperature controller positioning groove is provided on the heat insulation cover, aligned with the position of each temperature controller, and each temperature controller is installed in the aligned temperature controller positioning groove. The above technical solution has a reasonable structural design, sufficient distance between the heating tube and the heat insulation cover to avoid direct metal-to-metal contact and conduction of heat, preventing heat loss from the heater; it also features slow heat loss, good heating effect, reliable temperature controller fixation, long service life, and good practicality.
