Abstract

The utility model relates to a cast iron electric cooker comprising a cooker lid, a cast iron cooker, a heating element, a casing, a seat, etc., wherein, the heating element is a sealed type cast iron electric heating element. The utility model is characterized in that the cast iron electric cooker has two structures; an electrothermal element is cast and sealed in a heat conducting sheet on the cast iron cooker by sealing material, and the cast iron cooker, the electric heating element, the casing, etc. Form a mutually integrative structure; the electrothermal element is cast and sealed in a heat conducting sheet of a concave cast iron heat conducting plate, and the cast iron cooker, the electric heating element, the casing, etc. Form a mutually separated structure. The utility model has the advantages of quick temperature rise, uniform heating, high thermal efficiency and favorable thermal insulation effect, and the cast iron electric cooker can be used in multiple purposes, such as stir-baking, baking, steaming, boiling, frying, braising, instant-boiling, etc.

Description

Cast iron electric cooker

The utility model relates to kitchen utensils; Particularly relate to a kind of home-use electric food warmer.

Casting iron pan is the conventional kitchen apparatus that China follows in the successive dynasties.This pot not only helps human body the irony element is absorbed; And economical and practical, simple being suitable for.In the international market, China is world-famous with the outlet of casting iron pan.Studies have shown that according to international expert the irony unit of needed by human body have more than 50% and obtains from iron cooker.Therefore in the eighties, the United Nations's health organization once recommended to use the casting iron pan of China to the world.

In recent years, universal day by day along with household appliances, various types of electric food warmers, electric cooker, electric frying pan etc. also extensively enter urban and rural households, for people's lives are brought great convenience.But these product majorities are aluminium matter pot bodies, and separate each other with heater, and the electrothermal part in the heater then belongs to exposed type, thereby slow, the rapid heat dissipation of conducting heat in actual use, insulation is poor, heat waste is big; And the use all the year round of aluminium matter pot body, both be unfavorable for the picked-up of human body to the irony element, also lack the peculiar traditional flavor of casting iron pan.

The utility model is to keep the distinctive traditional flavor of casting iron pan, guarantee the picked-up of human body to the irony element, and raising thermal efficiency, reduce the purpose of thermal losses, providing a kind of based on casting iron pan, is the multi-functional Electric heating cast iron pot and the split type Electric heating cast iron pot of thermal source with sealed cast iron electric heating element.

Substance of the present utility model is to utilize the heat conduction of cast iron soon and even, and thermal inertia is good, and amount of stored heat is big, is incubated characteristics such as lasting, and will have aluminium matter pot structural reform now is cast iron pot body; Developing a kind of simultaneously is the sealed cast iron electric heating element of heat carrier with cast iron.The combination of these two contents can realize the technological revolution of China's tradition casting iron pan, can remedy many deficiencies of existing various aluminium matter electric food warmers again.Accompanying drawing 1 and accompanying drawing 2 are two embodiment of the present utility model.

Below in conjunction with accompanying drawing two embodiment are elaborated:

1. the embodiment among Fig. 1 one is casting iron pan and the sealed cast iron electric heating element structure of one each other.Its compound mode is:

(1) when casting iron pan 7 cast forms, is cast with two groups of conducting strips 8 at least simultaneously on the pot body.Conducting strip can be selected spirality, collar-shaped, quincunx, linear arranged side by side or the like respectively for use.

(2) heating 6 is sealed in two groups of conducting strips, the 8 formed grooves by encapsulant 9 die casting.But metal materials such as encapsulant aluminium, copper, tin, lead; Also can select nonmetal encapsulant for use.

(3) connected by interconnect 5 in the two ends of heating 6, and be connected in the supply socket 15 with earth connection 10.

(4) casting iron pan 7 is assembled in the inner chamber of shell 11, and with shell 11, base 3, foot 4 is formed one; Space between casting iron pan 7 and shell 11 is filled with insulation material 14.

Among Fig. 11 is handle of pot lid, the 2nd, pot cover, the 12nd, shell handle, the 13rd, sealing ring.

2. the embodiment among Fig. 2 two is skillet iron and sealed cast iron electric heating element structures of monomer each other, and its structural principle is identical with embodiment one basically, and following some difference is just arranged:

(1) sealed cast iron electric heating element is to be cast with two groups of conducting strips 8 on the bottom surface at least, it is main body that outer rim has the matrix cast iron heat conducting disk of all bracing rings 17, with encapsulant 9 and insulation material 14 heating 6 die casting are sealed in two groups of formed grooves of conducting strip, constitute a kind of by heating and the spill heat conducting disk structure of one each other.

(2) sealing formula cast iron electric heating element is packed in the inner chamber bottom surface of shell 11, and is positioned at the position of support casting iron pan 16.

(3) casting iron pan 16 is a kind of round-bottomed frying pan formula pot bodies that have hingle 18, and this pot body and shell 11 and sealed cast iron electric heating element are the isolating constructions of monomer each other.

The utility model is the technological revolution that traditional characteristics of China's casting iron pan and modern science and technology are combined closely. It also has capable of regulating power except being conducive to the picked-up of human body to the irony element, quick heating, and homogeneous heating, thermal efficiency height, thermal inertia and high insulating effect, safe and reliable Etc. characteristics, and have stir-fry, the several functions such as iron, steam, boil, explode, boil in a covered pot over a slow fire, rinse. Particularly after finishing whole cooking operations, the waste heat after also can sharply cutting off the power supply is afterwards boiled in a covered pot over a slow fire ripe two jin of rices with hot water.
