Abstract

The utility model relates to a kitchen electric heating cooker, particularly a new electric heating pan made of cast iron. The utility model is characterized in that an electric heating body (3) at the bottom of a pan body (2) is provided with convex points or a convex ring which are provided with screw threads. An electric heating pipe (7) is fastened by metal powder (4) and a clamping plate (6) through bolts (5) on the convex points or the convex ring. The utility model has the advantages of no strict requirements to the dimensions of the contact surface of the pan body (2) or the electric heating body (3) with the electric heating pipe (7), rapid temperature rise, uniform heat, simple manufacture process of the product, low production cost and good effect. The utility model can be used for a multifunctional electric heating pan, or an iron plate frying pan, etc.

Description

A kind of novel Electric heating cast iron pot

The utility model relates to a kind of kitchen electric-heating cooking utensil, a kind of new product that structurally is fit to make novel interior heat or external-heat Electric heating cast iron pot.

The original characteristics such as needs that casting iron pan is durable, wear-resisting with it, people eat picked-up to the iron essence, be subjected to people's welcome deeply, the electric food warmer of producing both at home and abroad with regard to its electric heating version, has following three kinds: 1. with electrothermal tube and disposable casting of cast iron iron pan or casting forming at present.2. the pot bottom face is made groove, and electrothermal tube is inserted in the conducting strip of these grooves formation, carry out die casting or casting with metal material again.With electrothermal tube with a direct fastening bottom of pot body of metal tray.There is following shortcoming and defect in these structures: the first two is planted owing to belong to rigid contacting between casting iron pan and the electrothermal tube, when electric food warmer during at the hot state of height, electrothermal tube is different owing to the coefficient of expansion with pot body contact site, crack performance appears in long-time use easily, and percent defective is higher during fabrication.The back is a kind of, and it is little that an electrothermal tube and a pot body connect area, also can form air-gap simultaneously, influences life of product equally.

The utility model with follow-on technical scheme, and provides a kind of modified Electric heating cast iron pot new product in order to overcome the shortcoming of said structure.

The utility model is to realize like this, the electric heating body housing of the bottom faces of cast iron pot body or bottom of pot body, have several salient points or protruding circle during casting, have Luo silk mouth on these salient points or the protruding circle, electrothermal tube is pasted clothes around these salient points or protruding circle, with fritter clamping plate and screw, electrothermal tube is clamped electrothermal tube by the screw-socket on salient point or the protruding circle, filling will be carried out with metal powder material around the electrothermal tube again, preferably with whole covering on the whole electric heating face, and with the high temperature pug whole surface is all smeared and to close, prevent that metal powder material from outwards overflowing, after the pug oven dry, whole electric heating body is sealed with rock wool and capping.If do not adopt the fritter clamping plate, clamping plate are made a firm dome.Like this, electrothermal tube, metal powder material, it is close directly with clamping plate it to be clamped envelope, can save material and technologies such as high temperature pug, rock wool, capping, manufactures simpler.

The utility model also has following advantage:

1. realized the soft draw bail of metal mold between cast iron pot body or cast iron electricity heating housing and the electrothermal tube, overcome under high temperature impact, the crack performance that cast iron pot body occurs easily, and prevented the shortcoming that the waste product of the disposable casting appearance of electrothermal tube and cast iron pot body can not be repaired.

2. improved with supporting plate electrothermal tube has directly been carried out fastening structure with the pot body, the contact site of cast iron pot body or cast iron electric heating housing and electrothermal tube and pallet, also need not be with half slot and strict dimensional requirement, thereby manufacture technology is simple, the cost cost is low, and the existence of the metal powder around the electrothermal tube, makes it increase area of dissipation, and radiating surface is even, has prevented the existence of air-gap and the problems such as electrothermal tube life-span reduction that cause.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing:

Embodiment 1: a kind of novel split cast iron is used electric food warmer more, Fig. 1 is the schematic diagram of present embodiment 1, below in conjunction with its CONSTRUCTED SPECIFICATION of present embodiment 1 explanation: this embodiment is made up of the electric heating body (3) of pot cover (1) pot body (2) and bottom etc., the housing of electric heating body (3) is made by cast iron, a circular plate shape, top and should have a contact-making surface that coincide with pot body (2), 3 convex points have been worn in its underpart, on these convex points and have a screw-socket, electrothermal tube (7) is placed on around electric heating body (3) the convex point, and fill with the most handy iron powder of metal powder (4), its thickness should be not less than the diameter of electrothermal tube (7), use a hood-shaped metal splint (6) electrothermal tube (7) metal powder (4) to be fastened on the electric heating body (3) again by the screw (5) of convex point, other structure and common electric food warmer are basic identical, are no longer giving unnecessary details.When energising was used, because the existence of metal powder (4) has increased heat-conducting area between electrothermal tube (7) and the electric heating body (3), so the interior temperature of pot is carried and opened very soon, and temperature was even.The present embodiment Electric heating cast iron pot, especially for frying food, effect is better.

Embodiment 2: a kind of novel cast iron electric frying pan, Fig. 2, it is the schematic diagram of this enforcement, below in conjunction with Fig. 2 its basic structure details is described: the pot body (2) of present embodiment adopts casting technique cast form, and directly cast the circular protruding circle of 2 different radiis in the bottom faces of its pot body (2), on each protruding circle, all have 3 screw-sockets, 2 electrothermal tubes (7) are placed on around 2 protruding circles, use fritter clamping plate (6) with screw (5) electrothermal tube (7) all to be clamped again by the screw-socket on the protruding circle, iron powder is still adopted with metal powder (4) in fastening back, electrothermal tube (7) is buried filling, preferably with its compacting, using high temperature pug (9) that its surface is smeared again closes, after oven dry, put (10) with metal envelope the whole face of closing of smearing is all sealed, in order to increase heat insulating ability, install some rock wools (8) in sealing cover (10) additional, other structure is identical substantially with embodiment 1.Be the structure of one because present embodiment is a kind of electrothermal tube (7) with pot body (2), the heat of electrothermal tube (7) is directly transferred on the use face of a pot body (2), and thermal loss is little, and quick heating is fit to make products such as electric frying pan, electric frying pan very much.
