Improved temp control equipment and safe electric connector of electric water heaters and electrolthemal kettles

Abstract

This invention relates to a temp control device electric connector and hot-water generator in which, the temp control device includes vapour temp controller and switch magnet keep relay composed of moving, static contact components and magnetic circuit composed of coils, iron core and permanent magnet inserted in its inner core. The connector contains a male plug and a female socket, an earth contactor is mounted on the shaft core of the plug, loop contactors are designed on the same core shaft connecting with the temp control device and heater. The female socket includes a base seat, cover plate, and spring, and a hot water bottle includes a container and a base.

Description

technical field [0001] The invention relates to a temperature control device, an electric connector and an electric water heater without electric wires. Background technique [0002] At present, the structure of the temperature control element used to control water heating includes a body, a movable contact, an electrical connector, a temperature-sensitive bimetal, and a push rod. When in use, the temperature-sensitive bimetal sheet is pasted on the heating surface or the bottom of the container. When the water in the container is boiled dry, since the push rod is clamped between the temperature-sensitive bimetal and the movable contact piece, the temperature-sensitive bimetal will be warped and the movable contact piece will be opened to make it connect with the electrical connector. Separate, cut off the power supply and stop heating to achieve the purpose of temperature control. Its disadvantage is that the temperature-sensitive bimetal sheet ...

Problems solved by technology

[0004] However, the electrical connector of this structure is not safe, because the electrical contacts in the socket of the base unit are directly connected to the power supply, if the electrodes are artificially touched, it is easy to cause injury

[0005] There are two disadvantages in installing the above-mentioned temperature control element and electrical connector in the electric kettle. One is that the steam thermostat that controls the disconnection of the heater is often installed at the bottom of the container. Steam leaks, and the steam cannot be transported to the thermostat in time, which affects the working performance of the thermostat. Even if the water in the container boils, the thermostat cannot cut off the heating part, so the work is unreliable; and the bottom of the container accumulates Water with vapor formation, inconvenient to use

The second is that the electrical connector is unsafe. Since the socket jack on the base unit is exposed, and the electrical contacts in the jack are directly connected to the power supply, it is easy for people to touch the electrodes in the jack and cause injury. , and such a plug-in method, the contact electrode is prone to arcing, causing surface oxidation, resulting in heat damage to the connecting parts
