AI Technical Summary

Technical Problem

The thermostat of the existing dishwasher heater uses an integrated structure, which results in high manufacturing costs, complicated maintenance, and environmental problems, and makes it difficult for users to replace it themselves.

Method used

The thermostat is divided into an independent automatic thermostat and a manual thermostat, adopting a modular design. The automatic thermostat is used to detect the preset temperature and disconnect the circuit, while the manual thermostat is used to disconnect the circuit when the temperature exceeds the danger level and can be manually reset. The two are fixed by a snap-fit ​​method.

Benefits of technology

It reduces production and maintenance costs, reduces electronic waste, allows users to replace damaged modules themselves, simplifies the maintenance process, and conforms to the concept of green environmental protection.

Abstract

This utility model discloses a modular thermostat for a dishwasher heater, comprising: a housing, a fixing clip, an automatic thermostat, and a manual thermostat; the housing has two accommodating cavities for housing the automatic and manual thermostats respectively; the fixing clip is fixed to the housing and has two snap-fit ​​holes coaxial with the two accommodating cavities respectively; the automatic and manual thermostats are snap-fitted into the two snap-fit ​​holes respectively, and are set as two independent, standard-compliant modular components, with dimensions and interfaces matching the snap-fit ​​holes; the manual thermostat is equipped with a reset button. In this way, the expensive integrated structure is broken down into two standardized independent modules, reducing costs; the manual thermostat replaces the function of a fuse and can be manually reset, avoiding frequent replacement costs due to fuse blowouts, reducing electronic waste, and conforming to the concept of green environmental protection; the snap-fit ​​fixing method lowers the maintenance threshold and time cost.
