Automatic reset temperature controller

Abstract

The invention discloses an automatic reset temperature controller, which comprises a sealed induction system and a signal power transmitting system, wherein the sealed induction system consists of a corrugated pipe, a capillary tube, a progressive wheel, a micro switch and the like. The automatic reset temperature controller is characterized in that: a lug boss is formed on the inner wall of a switch box of the micro switch, the lug boss corresponds to a contact, and the height of the lug boss relative to the inner wall of the switch box is 1.2+ / -0.05 millimeter. Because the lug boss is directly formed on the inner wall of the switch box of the micro switch, the automatic reset temperature controller has a simple structure and a few components, reduces the cost, solves the problem of troublesome screw adjustment, effectively avoids the problem of loosening due to the adoption of a screw, and ensures the precision of temperature control.

Description

technical field [0001] The invention relates to a temperature controller, in particular to an automatic reset temperature controller for household appliances, belonging to the technical field of automatic control machinery. Background technique [0002] figure 1 Schematic diagram of the structure of the micro switch of the traditional automatic reset temperature controller Figure 1 ; figure 2 Schematic diagram of the structure of the micro switch of the traditional automatic reset temperature controller Figure II ; image 3 It is a schematic diagram of the overall structure of a traditional automatic reset temperature controller. [0003] Such as Figure 1 to Figure 3 As shown: Most of the current household appliances have adopted temperature controllers to control the working status of household appliances, and the automatic reset type temperature controllers currently on the market, the distance between the contacts of the micro switch 1 is manually adjusted.

Problems solved by technology

[0003] like Figure 1 to Figure 3 As shown: Most of the current household appliances have adopted temperature controllers to control the working status of household appliances, and the automatic reset type temperature controllers currently on the market, the distance between the contacts of the micro switch 1 is manually adjusted. Adjust the screw 2 to adjust, and then carry out temperature control, that is, adjust the screw 2 to a suitable position, and then fix the screw 2 with glue. This kind of switch control temperature method is not only complicated in process, but also requires many parts. The cost is also very high, and the screw 2 used for temperature adjustment is easy to loosen, which leads to the problem of poor temperature control effect
