Mounting method for temperature transmitter thermosensors of electric cooker

Abstract

The invention relates to a mounting method for temperature sensor thermosensors of an electric cooker. The mounting method comprises the following steps: providing an inner shell (1) with a bottom punched with two T-shaped guide feet and a turnup hole for positioning and fixing extracted leads (11); providing an outer shell (4) with a bottom punched with a round hole and two guide grooves in the round hole; mounting a temperature control element (10) in a groove of tablettings (7), penetrating the leads (11) wrapped by a sleeve out of the turnup holes at the bottom of the inner shell (1) to be tightly matched with and fixed on the turnup holes; arranging the tablettings (7) between the inner shell (1) and an aluminum cover (13) to be riveted and compacted and using the tablettings (7) to compact temperature control element (10); supporting the inner shell (1) in the outer shell (4) by springs (12), penetrating the leads (11) wrapped by the sleeve out of the round hole of the outer shell (4), and penetrating the T-shaped guide feet of the inner shell (1) out of the round hole of the outer shell (4) to be bent in the guide grooves of the outer shell (4). The mounting method for the temperature sensor thermosensors of the electric cooker can reduce materials, decrease the cost, improve the qualified rate and ensure the product to be more reliable in the working process.

Description

Technical field [0001] The invention relates to a method for manufacturing a temperature sensor of an electric cooker, in particular to a method for installing a thermal element of the temperature sensor of an electric cooker. Background technique [0002] At present, in the rice cooking temperature control of the rice cooker, in addition to using the traditional magnetic steel temperature limiter to limit the temperature, there are also temperature sensors that use snap-type thermostats and thermistors as the thermal elements for cooking. temperature control. Although the magnetic steel temperature limiter has a simple structure and low price, the magnetic steel is fragile, and it is difficult to find the hidden danger of defective products. Although the temperature sensor using sudden jump thermostat and thermistor is more expensive for cooking temperature control, the former improves the reliability and pass rate, and the latter not only works reliably, but also realizes a var...

Although the magnetic steel temperature limiter is simple in structure and cheap in price, the magnetic steel is fragile and there are hidden dangers of defective products that are difficult to find

Although it is more expensive to use the temperature sensor of the sudden jump thermostat and thermistor to control the temperature of cooking, the former improves the reliability and the pass rate, and the latter not only works reliably but also uses the microcomputer chip to realize multiple function control. These two temperature control methods require wires to lead out signals from the temperature sensor. In order to fix the lead wires, additional welding brackets must be positioned, which not only wastes manpower but also increases the waste of resources.

In addition, in order to be universal and reduce costs, the magnetic steel temperature limiter hardware is often used to make some improvements and install the thermistor temperature sensor. In this way, although the versatility is good, the burrs on both sides of the thermistor pressing sheet are easy to cut through. Insulation sleeve, resulting in more defective products
