Description
Technical Field
The invention relates to the technical field of main temperature controllers of electric cookers, in particular to a main temperature controller without a ground wire.
Background
At present, the mainstream electric rice cooker uses a main temperature controller with a temperature sensing element as a thermistor to replace the traditional temperature sensor adopting a magnetic steel suction device, and fully utilizes the advantages of large temperature controllable range and good control performance of the thermistor. The structure of the existing main temperature controller adopting the thermistor is shown in figure 1, and comprises a silk-hat-shaped temperature sensing cap main body 1 which is positioned at the bottom of an inner container of an electric rice cooker during installation, wherein the inner top of the temperature sensing cap main body 1 presses the thermistor 3 to be tightly attached to the inner top surface of the temperature sensing cap main body 1 through a support 2, and the support 2 is installed through interference fit with the inner peripheral wall of the temperature sensing cap main body 1. In this mounting method, since the temperature sensing cap body 1 and the holder 2 are both metal members and are in contact with the thermistor 3, the ground wire 4 needs to be provided to comply with 3C security certification. However, the addition of the ground wire 4 not only increases the welding process and the projection or bayonet structure for welding the ground wire 4, but also increases the assembly time and the installation cost of the ground wire 4 itself, resulting in an increase in the cost of the entire main temperature controller.
Disclosure of Invention
The invention aims to provide a main temperature controller without a ground wire, which can reduce the cost on the premise of ensuring the safety.
The main temperature controller without the ground wire comprises a temperature sensing cap main body with a silk-hat-shaped section, wherein a heat conduction insulating gasket and an insulating mounting support are arranged at the inner top of the temperature sensing cap main body, a thermistor is clamped between the heat conduction insulating gasket and the insulating mounting support, a threading hole for a connecting wire of the thermistor to pass through is formed in the insulating mounting support, the heat conduction insulating sheet is attached to the inner top surface of the temperature sensing cap main body, and the insulating mounting support is positioned and fixed through a concave point which is inwards concave in the peripheral wall of the temperature sensing cap main body.
The main temperature controller without the ground wire adopts a sandwich mode of the heat conduction insulating gasket and the insulating mounting bracket to fix the thermistor, and avoids the contact between the thermistor and the metal shell of the main temperature controller, thereby saving the mounting cost of the ground wire, simplifying the production process of the main temperature controller and improving the production efficiency.
Furthermore, the bottom of the threading hole is connected with a threading sleeve, and the threading sleeve and the insulating mounting bracket are integrally formed. The threading sleeve can replace a traditional wiring harness binding belt, save the binding process and improve the production efficiency.
