Thermostat for household appliances and assembly method thereof

Abstract

The invention discloses a thermostat for household electrical appliances and an assembly method thereof, and relates to a thermostat. The key points of the technical solution include a casing with a temperature control element installed inside, a temperature-sensing cover fixed on the casing, and a thermostat. Mounting seat; wherein, the temperature-sensing cover is provided with an outer edge which is polygonal and arranged around the outer wall of the temperature-sensing cover, and the outer wall of the outer edge is provided with a ring of grooves arranged circumferentially on the outer wall of the temperature-sensing cover. The middle position of the mounting seat is provided with a through hole that is equal in size to the shape of the outer edge; among them, when the mounting seat and the temperature sensing cover are rotated and snapped together, stamping holes are used to clamp and fix the mounting seat at each corner of the outer edge The pinch point; the present invention has the effect of ensuring the connection strength between the installation base and the temperature-sensing cover.

Description

technical field [0001] The present invention relates to a thermostat, more specifically it relates to a thermostat for household electrical appliances and an assembly method thereof. Background technique [0002] like figure 1 As shown, the existing electric baking pan (electric oven) is generally divided into an accommodating chamber 12 for placing circuit boards, etc., and a heating chamber 13 for placing power supply heating rods, etc., through a partition 11. Place a heating element 14 similar to a baking pan on it. When installing the thermostat 2, it generally fixes the thermostat 2 on the partition 11 by clamping and fixing the thermostat 2 with bolts 23 and nuts 231, so that the thermostat 2 can Protruding into the heating chamber 13 and attaching to the lower surface of the heating element 14 to perform temperature sensing work, therefore, a thermostat is indispensable in various household electrical appliances that may produce electric heating work.

AI Technical Summary

Problems solved by technology

[0004] Similar to the above in the prior art, the thermostat generally includes a housing (support), various temperature control elements installed in the housing, a temperature sensing cover for temperature sensing, and a thermostat for installing the thermostat on the electric heater. The mounting seat in the kitchenware 1; however, the prior art is the same as that disclosed in the specification and the accompanying drawings. The existing mounting base is generally fixed together with the temperature-sensitive cover by means of buckles and slots that are engaged with each other. During the clamping process, the connection between the mounting base and the temperature-sensing cover will be deformed, resulting in a change in the hole diameter of the card slot, which will affect the connection strength between the mounting base and the temperature-sensing cover, and cause the mounting base to be easily removed from the temperature-sensing cover. fall off
