Abstract

PURPOSE:To allow a cooking plate to be removed from a body and to be put directly over a gas range or the like of a high fire power by pressing a plate material consisting of aluminum or aluminum alloy to form the cooking plate and forming an alumite layer on the rear surface thereof. CONSTITUTION:The cooking plate 10 molded by pressing the plate material consisting of the aluminum or aluminum alloy can be freely attachably and detachably mounted in the body 1. The black alumite layer 11 having 100 Shore hardness HRS is formed as a black anodized film on the rear surface of the cooking plate 10. The cooking plate 10 which is formed with the black alumite layer 11 on the rear surface can be directly heated by the cooking appliance, such as gas range, having the high fire power. The time for cooking is shortened by removing the cooking plate 10 from the body 1, putting the plate over the gas range of the high fire power and making preparatory cooking if a large volume of water is going to be used as in the case of cooking in the boiling water in a pan. The cooking plate 10 is again mounted to the body 1 upon ending of the preparatory cooking and is used for cooking and heat retaining.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an electric cooker equipped with a removable cooking plate that can be heated even by a gas stove with strong heat.

[Prior Art] FIG. 4 is a perspective view showing an example of a conventional electric cooking device, and FIG. 5 is a longitudinal sectional view of FIG. 4. In the figure, (1) is the main body of the electric cooker, and (2) is a cooking plate made of aluminum casting that is detachably attached to the main body (1). (3) is a heating plate that is provided in the main body (1) and heats the cooking plate (2) in contact with the cooking plate (2), and (4) is a heater (5) embedded in the heating plate (3). is a temperature regulator that controls electricity supply to the heater (4).

Note that (8) is a lid that covers the cooking plate (2).

Next, the effect will be explained. When cooking inside the cooking plate (2), first turn on the power and supply power to the heater (4) via the temperature regulator (5).When the heater (4) is heated, the hot plate (3) is heated. The cooking plate (2) is heated by conduction of heat, so the cooking plate (2)
You can cook inside.

[Problems to be solved by the invention] Conventional electric cookers configured as described above have weaker heat power than those heated by gas stoves, etc., and therefore, when cooking dishes that use a large amount of water, it is difficult to cook. The problem was that it took a long time. On the other hand, if you put the cooking plate (2) directly on a gas stove with strong heat to shorten the cooking time, if the cooking plate (2) is made of cast aluminum, it may cause blisters or damage the surface that touches the trivet of the gas stove, etc. There were problems such as soot adhesion and deterioration of the aesthetic appearance.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to obtain an electric cooker equipped with a cooking plate that can be directly used in cooking appliances with strong heat such as gas stoves.

[Means for Solving the Problems] In the electric cooking device according to the present invention, a cooking plate is manufactured by pressing a plate material of aluminum or aluminum alloy with a thickness of 2 m+s or more, and a black alumite layer is coated on the lower surface of the cooking plate. was formed.

[Function] For example, when cooking a dish that uses a large amount of water, first heat the cooking plate on a gas stove with strong heat for pre-cooking, then transfer the cooking plate to the main body of an electric cooker and heat it. Electric heating (or heat retention) is performed.

[Embodiment of the Invention] FIG. 1 is an exploded perspective view of an embodiment of the invention, FIG. 2 is a longitudinal sectional view of the embodiment of the invention, and FIG. 3 is a longitudinal sectional view of the main part of FIG. 1. Note that the same or equivalent parts as in the conventional example shown in FIGS. 4 and 5 are given the same reference numerals, and their explanation will be omitted. In the figure, (
lO〉 is a cooking plate formed by pressing a plate material made of aluminum or aluminum alloy with a thickness of 2 mm or more, and can be detachably attached to the main body (1〉. In this example, the thickness A 2.5 mm aluminum alloy plate was used. (1l> is a cooking plate.
In this example, the black anodic oxide film (hereinafter referred to as black alumite layer) formed on the lower surface of 10) formed a black alumite layer (11) having a Shore hardness of H R S of 100.

In this way, the cooking plate (lO) with the black alumite layer (l1) formed on its lower surface can be directly heated by a cooking utensil with strong heat, such as a gas stove.

(7> is the thermostat attached to the hot plate (3) via the heat conductor (8), (9) is the temperature control knob, (9a> is the temperature control knob (9) which transmits the movement of the temperature control knob (9) to the thermostat <7>) It is a transmission mechanism. Note that (l2) is a power cord.

Next, the operation of the present invention configured as described above will be explained.

To set the heating temperature of the cooking plate to the desired temperature, move the temperature control knob (9> in the direction perpendicular to the page), and the movement will be transmitted to the thermostat (7) via the transmission mechanism <9a>. The thermostat (7) is adjusted in response to the set temperature.This controls the power supply to the heater (4), allowing cooking on the cooking plate (10) heated to the desired temperature. Become.

Also, when using a large amount of water such as when cooking in a pot, you can shorten the cooking time by removing the cooking plate (lO) from the main body (1) and pre-cooking it on a gas stove with strong heat. I can do it. When the pre-cooking is finished, the cooking plate (10) is attached to the main body (1) again to perform cooking and keeping warm.

According to the experimental results, the cooking plate (10) has a thickness of 2
．． Since the 5 mm aluminum alloy was molded by press working, no blisters occurred even when heated with a strong gas stove, etc., and deformation due to heat was within the allowable range of 0.15 mm or less. In addition, the black alumite layer (1i) provided on the bottom surface of the cooking plate (1i) efficiently absorbs radiant heat, reducing the time required to boil water on a gas stove by approximately 5%.
I was able to shorten it.

Furthermore, the hardness of the black alumite layer (1L) is higher than the materials generally used for trivets (for example, cast aluminum), so even when hung on the trivet, the bottom surface of the cooking plate (1L) is unlikely to be scratched, and the alumite layer Since (l1) was originally black, it was not noticeable even if soot adhered to it.

[Effects of the Invention] As is clear from the above description, the present invention provides a cooking plate in which an aluminum or aluminum alloy plate is formed by press working, and an alumite layer is formed on the lower surface of the cooking plate.
Since the electric cooker can be removed from the main body and hung directly on a gas stove or the like, it is possible to significantly shorten the cooking time for dishes that require a large amount of water, and also to obtain an inexpensive electric cooker.
