Jumper type temperature controller of electrothermal water boiling kettle

Abstract

The invention relates to a jumper type temperature controller of an electrothermal water boiling kettle, which comprises a cover plate, a main body and a chassis connector, wherein a high temperature metal sheet is installed on the cover plate; a low temperature metal sheet, an L-pole copper ring and an N-pole copper ring are installed at the bottom of the main body, the L-pole copper ring contacts an L-pole fixed frame through an L-pole conducting sheet, the N-pole copper ring contacts an N-pole fixed frame through an N-pole conducting sheet, a jumper is installed on the main body, the jumper is provided with stops A, B and C, the stop A contacts the L-pole conducting sheet, the stop B contacts the N-pole conducting sheet, and the stop C contacts the low temperature metal sheet; the chassis connector is provided with an L-pole contact sheet, an N-pole contact sheet and a grounded contact sheet, the L-pole contact sheet contacts the L-pole copper ring, the N-pole contact sheet contacts the N-pole copper ring, and the grounded contact sheet contacts the cover plate through a grounded shaft; and the electrothermal water boiling kettle jumper type temperature controller is characterized in that a hollow column A and a fixed column are manufactured on the main body, an open slot is manufactured on the hollow column A, a big-end post rod is installed in the hollow column A, the big-end post rod contacts the chassis connector, a spring A is fixed on the fixed column, and the spring A penetrates through the open slot to contact the top surfaces of the big-end post rod and the jumper.

Description

technical field [0001] The invention relates to a jumper-type temperature controller for an electric heating kettle, belonging to the field of household appliances. Background technique [0002] Electric kettles are easy to use, reliable in boiling water, high in power, fast in heating speed, and relatively hygienic, so they are widely used in hotels and families. When the water is boiled, the electric kettle needs to automatically cut off the power supply, or sometimes improper operation may cause problems such as dry boiling, so it is necessary to configure a temperature controller. There are many types of temperature controllers used for electric kettles. For example, the Chinese patent ZL 03131983.1 applied by the inventor, "Electric Kettle Thermostat", although it is safe and reliable in use, the contact performance of the L pole and N pole contact piece is good. , will not be offset, and the heat dissipation space between the bottom plate and the upper part of the mai...

Problems solved by technology

There are many types of temperature controllers used for electric kettles. For example, the Chinese patent ZL 03131983.1 applied by the inventor, "Electric Kettle Thermostat", although it is safe and reliable in use, the contact performance of the L pole and N pole contact piece is good. , will not be offset, and the heat dissipation space between the bottom plate and the upper part of the main body is large, but there are the following disadvantages: First, when the main body is plugged into the chassis connector (the chassis connector is connected to the power supply), the current is immediately turned on, It is easy to generate sparks on the L-pole copper ring and the N-pole copper ring, which will blacken the L-pole copper ring and the N-pole copper ring or even melt the copper ring into a gap, which will affect the function and appearance; the second is that the jumper directly contacts the high-temperature metal sheet contact with each other, and the jumper is made of plastic material, which is easy to deform due to high temperature, resulting in the failure of the entire product function; third, the contact piece of the chassis connector (base connection component) has a complex structure and troublesome installation, especially the moving contact piece and the connection A tension spring is used to connect the bracket of the controller. Once the tension spring fails, the temperature controller will be scrapped; the fourth is that the grounding shaft contacts the iron plate (cover plate) through the grounding insert of the main body. The structure is complex, there are many parts, and installation is troublesome. One part, one more damaged link
