Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric cooker, by providing an electric cooker with an open function with a closed heating chamber.

By placing food materials in a sealed heating chamber and heating it, the sound of water vapor is trapped inside the chamber, creating a high pressure and high temperature state of 1 atm - 100°C or higher, allowing for faster cooking of pot and open dishes, and ultimately reducing fuel costs. The aim is to provide an electric cooker that can save on cooking. - Conventionally, the development of pressure cookers has made it possible to cook food in a pot at high speed, but pressure cookers can only cook stewed dishes. Due to high-speed simmering in a closed container, bluish fish and meat have the disadvantage of retaining a fishy odor.

The present invention has been made in order to eliminate the above-mentioned drawbacks of the conventional art.The present invention has been made in order to solve the above-mentioned drawbacks of the conventional art. By forming a sealed heating chamber with the container placed on the lower heater and the lid, it is possible to boil and boil at high speed like a pressure cooker in addition to conventional open cooking. steam,
Not only can you cook food such as cooking, but you can also roast large chunks of meat and potatoes at high speed.Moreover, since most of the time it is used in an airtight state, there is less heat dissipation and the cooking time is short, which reduces fuel costs. It is a device that can reduce the amount of heat and brown the surface of food materials, so that even meat and green fish do not have a fishy odor.

Hereinafter, the present invention will be explained based on the drawings showing an example of implementation. In Figure 0, (1) is an outer box that is bent into a substantially opening shape to constitute the main body, and the upper surface of the outer box is open approximately in the center. . The front and top of the inner box (61) formed by (4) are open.

Further, a back plate flfi is attached to the back of the outer box (1). Reference numeral 03 denotes a retaining ring attached to an opening at approximately the center of the upper surface of the outer box a), and an opening (131) is provided at approximately the center of the retaining ring, and a first retaining wall ( 13c) and second locking wall (13d)
Paragraph portions (13b) having the following shapes are formed at opposing positions. (14tli is a cylindrical container with a bottom, and a plurality of engaging flanges (14 m) are formed in a wave shape at appropriate intervals on the outer periphery of the upper end, and a pair of four engaging flanges (14 m) are formed at appropriate intervals in the circumferential direction. A pair of locking metal fittings 61- are fixed to the outer surface of the container 04 at the bottom of the engagement #1 (14a) (14a)O in correspondence with the stepped portions (13a) (13m) of the retaining ring 03. In addition, a container handle (I) is attached to the upper end of the winter suspension fitting 11- with a screw or the like. 071 is a lid body, and the engaging collar (14a) for the container I is attached to the lower periphery. An engaging claw (1)a) is formed to protrude inwardly to correspond to and engage with the engaging claw (17a), and a flexible annular backing 081 is placed above the engaging claw (17a). An operating hand 1VQ- having a grip portion (191) is fixed to the upper surface of the lid body 07+ so as to be positioned in the front-rear direction of the outer box (1). The rear end of the hand A/kiln is rotatably attached to the cover part attached to the upper part of the back plate aZ of the main body by a pivot shaft @n, and the operating hand A'Q9
On the front surface of the outer box (1), an operating knob (to) which is removably engaged with a hook attached to the front end of the upper surface of the outer box (1) is attached and biased by a spring or the like. (241 is a cover plate that covers the rear upper opening of the operating hand S/W.

- and - are a reflector and an upper heater airtightly attached to the inner surface of the lid 0η, and the end (261) of the upper heater is the first connector (material) fixed to the lower surface of the rear end of the operating hand V. )
It is electrically connected to by a wiring member.

In addition, an insertion hole (201) is provided at the upper end of the cover to allow the first connector to be inserted and retracted, and an insulating member is inserted into the lower part of the first connector inserted into the insertion hole (20a). A slidable second connector holder, which is always biased upward by a spring 4, is attached so as to correspond to the first connector holder. When the opening on the top surface is opened, the first connector (b) comes into pressure contact with the second connector 4, making it possible to supply electricity to the upper heater 4. This is a type 9 pressure regulating valve, which consists of a pressure regulating hole υ that penetrates the outside and a weight (2) that closes this pressure regulating hole 0 from above. When the load exceeds the load, the pressure is released to the outside.

In the above configuration, insert the container tJ41 filled with water into the interior through the opening (13a) of the retaining shell and open the lower heater (6).
