Description

Radio Technology

The utility model relates to a radio device, wherein a power cord is not connected to the main body of the electric appliance. Background technique

At present, in the electric water pot / pot design industry, it can be mainly divided into a wired electric water pot with a socket connected to a power cord on the main body of the electric water pot, and a power cord is not connected to the main body, and another base is connected. The power cord is connected with a wireless plug / socket between the two as a radio water boiler for power transmission.

In the design of the radio water boiler, the steam tube is generally arranged in the body of the main body. When the water is rolled away, the steam will diffuse through the steam tube to the bimetal of the steam switch, which will cause the bimetal to be heated and deformed to trigger the steam switch to jump. ON to cut the circuit.

The object of the present invention is to provide a radio with a steam switch. Summary of invention

A radio device according to the present invention is characterized by comprising:

Connect the base of the power cord;

An electrical appliance body that can be electrically connected to the base through a set of wireless plugs and sockets,

Steam switch installed in the base and cut off the power,

A steam pipe for steam diffusion that disconnects the steam switch, and the steam pipe is connected to the interior of the appliance body and the steam switch.

The steam pipeline of the present invention includes a first portion provided in the main body of the appliance and a second portion provided in the base, and the inlet of the second portion is connected to the outlet of the first portion.

In the design of an electric water boiler of this utility model, the steam pipe is divided into two parts. The first part is provided in the main body for guiding steam, and the second part is provided in the base of the water boiler, and is connected to the outlet of the steam pipe in the main body. Pass the steam to Kao Qin / Qin Qin, and make the steam switch jump off after boiling water in the water boiler.

-1-Replacement page (Article 26) The utility model has the advantages of making the appearance design of the electric water pot / pot more diversified and reducing limitations. In terms of the shape design of the electric water pot / pot in the future, it is no longer necessary to consider how to design the steam switch on the main body, which affects the simplicity of the overall water pot design.

The utility model also has the advantage that, because the steam switch is arranged in the base of the water boiler, the steam switch will not be affected by the heating wire and / or the heating environment in the main body of the boiler, and the water vapor will condense in the water after boiling for a long time. Affected by the humid environment inside the main body.

The utility model also has the advantage that, because the steam switch is not provided in the main body of the body, and the steam pipe does not guide the steam into any component in the main body of the water boiler, so the steam and the final water are not left in the main body of the main body. And it affects the electrical components in the main body of the body, such as heating wires and dry pot protectors.

The advantage of this utility model is that, because the steam switch is not inside the main body of the cooker, but is arranged in the bottom of the cooker, it allows the designer of the electric water boiler to design the ventilation system of the steam boiler more easily and comprehensively. Allows steam to spread out of the electric water pot faster and smoother. As a result, the temperature of the base of the water boiler is accelerated and lowered, and the steam switch recovers its function more quickly. This reduces the recovery time after the water boiled and boiled off. BRIEF DESCRIPTION OF THE DRAWINGS

The working principle of an electric water boiler is that when the water 4 in the water boiler is boiled, water vapor is evaporated, and the water vapor will enter the steam tube 6 in the main body through the steam tube inlet 5. The water vapor enters the steam channel 17 of the water pot base from the junction of the main body body and the steam passage of the pot base 1 0. Finally, it comes into contact with the bimetal on the steam switch 12. The bimetal is heated and deformed, so that the connection line of the electric water boiler shown in FIG. 2 is disconnected, so that a water boiler realizes the function of boiling water. When the water boiler is cooled, water vapor will condense into water droplets and flow out of the water boiler base through the water outlet under the steam switch.

The function of an electric water boiler also includes the functions of a general radio water boiler, such as the steam switch 12, heating wire 7, wireless plug and socket 9, 1 1 to be connected to Figure 2 to achieve normal steam disconnection, and It has the function of dry pot protection.

In addition, in the design of the water boiler of this utility model, in order to avoid that there may be other debris sand cores blocking the junction of the steam passage of the main body and the base of the body 10. A mechanical structure can be added in this place. For example, a spring-loaded rubber sheet seal is used to prevent debris from entering the steam pipe. When the main body of the main body is placed back into the base of the water boiler, this action will trigger the switch to open the mechanism, so that the steam pipes in the main body and the steam pipes in the base are connected, so that the steam can flow smoothly.

The steam pipe of this utility model can be arbitrarily designed in shape, manufacturing mode of the mold and the like. It is only necessary that the area inside the steam pipe is not less than 20mm ² .

The design of this practical new type electric water pot / pot is applicable to the design of the water pot of the floor heating wire, as well as the design of the water pot of the submerged heating wire.

Industrial application The design of this utility model is also applicable to any household appliance that uses vapor contact as a switch. As long as the power transmission part is the connection of the wireless plug / socket. The design of the steam tube can be divided into the design of the steam tube head and the seat.
