Abstract

The utility model discloses a heating device of an electric heating container, which comprises an aluminum plate, a heating pipe and a spring, wherein, the spring is sheathed outside the heating pipe, and the spring and the heating pipe are pressed into the aluminum plate by a pressing machine. The heating device of an electric heating container of the utility model adopts a novel heating device, so the utility model has the advantages of simple product structure, long service life, large and uniform cooking area, easy manufacture and high safety.

Description

The heater of electric-heating container

The utility model is about a kind of electric-heating container, more particularly about the heater of electric-heating container.

In the prior art, the heater of electric-heating container generally is divided into two classes: the first kind is exactly the electric furnace disc type, comprises resistance wire and electric furnace pan, this class heater is owing to be directly to expose, and therefore, fail safe is not high, get an electric shock easily, and the not high and easy damage of the heat efficiency; Second class is exactly heating tube and body of heater casting heating disc type together, this class heater manufacturing process complexity, with high costs and maintenance inconvenience.

The purpose of this utility model just provides a kind of heater of electric-heating container.

Of the present utility model this will further launch by following detailed description and illustrate with other purpose.

In the utility model, the heater of electric-heating container comprises aluminium sheet, heat-generating pipe and spring, and spring housing is outside heat-generating pipe, and spring and heat-generating pipe are pressed in the aluminium sheet with forcing press.

The heater of electric-heating container of the present utility model has been owing to adopted novel heater, so product structure is simple, long service life, cooking area is big and evenly, and easy to manufacture, safe.

In the utility model, described heater can be installed in the electric-heating container with mode identical with prior art and method, and described electric-heating container can be electric food warmer, electric cup, electric frying pan, electric rice cooker or the like.

Below further specify the utility model by accompanying drawing and explanation thereof.

Fig. 1 is the schematic diagram that is with the heat-generating pipe of spring.

Fig. 2 is the cutaway view after the heat-generating pipe that is with spring after the pressurization embeds aluminium sheet.

In Fig. 1 and Fig. 2, symbol 1 is represented spring; Symbol 2 is represented heat-generating pipe; Symbol 3 is represented aluminium sheet.

The heater of electric-heating container of the present utility model comprises aluminium sheet 3, heat-generating pipe 2 and spring 1, and wherein, spring 1 is enclosed within outside the heat-generating pipe 2, and spring 1 and heat-generating pipe 2 usefulness hydraulic presses are pressed in the aluminium sheet 3.Spring 1 and heat-generating pipe 2 give and be pressed into the cross section with forcing press earlier is polygon, and preferably, spring 1 and heat-generating pipe 2 give and be pressed into the cross section with forcing press earlier is triangle.Spring 1 and heat-generating pipe 2 are to imbed in the aluminium sheet 3 with the identical shape in aluminium sheet 3 neighborings, and the degree of depth of imbedding is 2mm～4mm, and preferably, spring 1 and heat-generating pipe 2 are imbedded in the aluminium sheet 3 with ring form, and the degree of depth of imbedding is 2mm～4mm; And the internal diameter of spring 1 is identical with heat-generating pipe 2 external diameters, and the length of spring 1 is shorter than heat-generating pipe 2.

Further, with a length than the short 3～4cm of heat-generating pipe, internal diameter is identical with heat-generating pipe 2 external diameters, steel wire diameter is that the spring 1 about 0.8mm is enclosed within on the heat-generating pipe 2, it is that (purpose is two plane parallel in heat-generating pipe 2 bottom surfaces and aluminium sheet 3 bottom surfaces that are pressed into aluminium sheet 3 at last in order to make to triangular shape that the heat-generating pipe 2 usefulness hydraulic presses that package spring 1 are pressed into the cross section, make and conduct heat evenly, reduce distortion).It is in the fine aluminium aluminium sheet 3 more than the 3mm that the heat-generating pipe 2 usefulness hydraulic presses that package spring 1 and be pressed into triangular shape are pressed into thickness, compression distance is about 2mm, thereby utilize the backward extrusion power of aluminium sheet 3 that spring 1 steel wire that is pressed into aluminium sheet 3 parts is pushed tightly, heat-generating pipe 2 and aluminium sheet 3 closely are interlocked.The last installation method of electric-heating container is routinely again installed container, container base, heater and electrical appliance part respectively and is made it to become final products.

In the utility model, because container, container base, electrical appliance part etc. are prior art, being connected of they and heater also is known to the public, seldom elaboration in specification thus.
