DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric cooking device such as a hot plate for grilling dishes and an electric pot for boiling dishes, which can be easily cleaned up after use.

Embodiments of the present invention shown in the drawings will be described in detail below.

First, in the hot plate shown in FIGS. 1 and 2, 1 is a plate body (cooker body) made of die-cast aluminum, and 2 is a heat generating device such as a sheathed heater integrally cast into the plate body 1. 3 is a temperature regulator that senses the temperature of the plate body 1 and controls the energization of the heating element 2 according to the change in temperature; 4.4 is a pair of handles fixed to the outer periphery of the plate body 1; 5; .5 is a pair of guard/carrier handles whose ends are pivoted to the handle 4.4 and can be raised and lowered; 6 is a reflector disposed on the bottom surface of the plate body 1; γ is a supporting leg of the plate body 1. be.

Reference numeral 8 denotes a cooking sheet placed on the inner surface of the plate main body 1 in the area used for cooking, that is, detachably attached to the cooking sheet, for example, a sheet manufactured by sufficiently impregnating a woven glass cloth with a fluororesin and baking it at a high temperature. (Product name from Chukoh Chemical Industry Co., Ltd.
There is one commercially available as "Cheuko Flow G Type".

) and has heat resistance, non-adhesiveness, and flexibility.

When grilling food is to be prepared using such a hot plate, a cooking sheet 8 is attached to the inner surface of the plate body 1, and the cooking is carried out on this cooking sheet 8.

Of course, when cooking on the cooking sheet 8, the cooking sheet 8 has a non-adhesive property so that the food to be cooked does not get scorched. Since it works effectively on things, it can be done in good conditions.

After use, all you need to do is take out the cooking sheet 8 from the plate main body 1 and wash it completely, and it is easy to remove cooking utensils, oil, etc. that have adhered to the cooking sheet 8 because the sheet 8 is non-adhesive. It can be washed away.

Therefore, unlike conventional hot plates in which cooking is performed directly on the inner surface of the plate body, the plate body, which is heavy and equipped with attached parts such as a handle, can be carried to the sink.
Not only does it eliminate the need for troublesome work such as washing off the cooking shaft, etc., but it also eliminates the problem of water flowing into the terminals of the heating element, making it easier to clean up after use. .

In the pot plate configured as described above, a part of the cooking sheet 8 is extended to a position protruding outside the plate body 1 as shown by dotted lines in FIGS. Then, the cooking sheet 8 can be easily taken out, and especially when the cooking sheet 8 is taken out immediately after use, the cooking sheet 8 can be taken out without touching the plate body 1 which is in a high temperature state.
It's safe.

In addition, the outer peripheral edge of the cooking sheet 8 may ride on the circular arc surface extending from the inner bottom surface to the inner surface of the plate main body 1, or the third
As shown in the figure, if the outer periphery of the cooking sheet 8 is made higher than the center by riding on the annular protrusion 10 protruding on the inner bottom surface of the plate body 1, excess cooking drippings and oil can be removed. Outflow onto the plate main body 1 can be prevented.

FIG. 4 shows another embodiment of the present invention, in which a heat-resistant, non-adhesive and flexible cooking sheet 8 is kept in a tensioned state using a shape-retaining means, and when the food is turned over during cooking. By preventing the cooking sheet 8 from wrinkling, cooking operations are made easier.

In FIG. 4, the outer periphery of the cooking sheet 8 is clamped and fixed by an annular shape-retaining frame 11 made of heat-resistant resin or metal to keep the sheet 8 in tension, while the outer periphery of the inner bottom surface of the plate body 1 A groove 12 is formed in the groove 12, and the shape retaining frame 1 is inserted into the groove 12.
By dropping the cooking sheet 8 onto the inner surface of the plate body 1.

With such a hot plate, the heat of the heating element 2 can be effectively applied to the food on the cooking sheet 8, and the cooking sheet 8 can be prevented from becoming wrinkled even when the food is roughly turned over. Furthermore, by setting the inner circumferential edge of the holding frame 11 to engage with the inner circumferential wall of the groove 12, movement of the cooking sheet 8 itself can be prevented, which is extremely convenient for cooking operations.

The shape-retaining frame 11 also serves to prevent excess cooking sauce, oil, etc. from flowing out.

In the embodiment shown in FIG. 4 as well, one end of the member (grip portion) having heat resistance and heat insulation properties is attached to the shape retaining frame 11, and the other end is made to protrude outward from the plate body 1. For example, the cooking sheet 8 and the shape-retaining frame 11 can be easily taken out.

In addition to the shape-retaining frame 11, the following types of shape-retaining means may be used as the shape-retaining means.

Examples include those in which the outer periphery of the cooking sheet 8 is folded back to contain a reinforcing wire inside, and those in which the outer periphery of the cooking sheet 8 is folded back and overlapped in double or triple layers to provide appropriate strength. .

In both the embodiments shown in Figs. 1 and 2 and the embodiment shown in Fig. 4 described above, the inner and outer circumferential parts of the plate body 1 are exposed, but these parts do not directly affect cooking and are subject to spilled oil and the like. However, compared to the parts that directly interact with cooking, there is very little dirt and it is easy to get dirty, so if you apply a non-adhesive treatment such as fluorine resin coating to the exposed inner and outer periphery, it will be possible to remove the spilled oil. etc., it can be easily removed.In this case, it is necessary to clean the plate body 1 as well as the cooking sheet 8, but cleaning the plate body 1 does not require the troublesome and time-consuming work described above. This eliminates the need for cleaning, making it easy to clean up after use.

Furthermore, in order to improve the cleanability of the inner and outer circumferential portions of the plate body 1, it is conceivable to apply an oxidation catalyst to the portions to perform a self-cleaning treatment and oxidize and decompose the attached oil.

In this case, a temperature of 200 to 300 degrees is required to fully exhibit the self-purification effect of the self-cleaning process, and the temperature controller 3 is adjusted to the normal cooking temperature range (100 to 200 degrees) as shown in Figure 5. ) to a temperature that satisfies the above conditions, for example, 250 degrees, and the temperature control knob 3' is provided with an SC scale corresponding to 250 degrees as shown in FIG.

Therefore, in this case, after cooking, the cooking sheet 8
When you take it out and turn the adjustment knob 3' to set the SC scale to the index, the self-cleaning effect will be activated by self-cleaning process, and the attached oil will be oxidized and decomposed.
Cleaning is easier.

Note that the surface of the plate body 1 to which the cooking sheet 8 is adhered does not need to be particularly subjected to non-adhesive treatment or self-cleaning treatment, and may be subjected to anti-corrosion treatment such as alumite treatment.

In the embodiment shown in FIG. 1, a cooking sheet 8 is formed into a shape that matches the inner surface of the plate body 1, and is adhered to the entire inner surface of the plate body 1.

Since the cooking sheet 8 is made of a heat-resistant woven fabric as a base material, it cannot be formed by pressing or the like, and therefore is formed into a predetermined shape by means such as bonding or sewing.

In the embodiment shown in FIG. 8, a shape-retaining frame 11 that keeps the cooking sheet 8 in a tensioned state is formed in a shape and size that covers the inner and outer peripheral parts of the plate body 1, and the shape-retaining frame 11 and the cooking sheet 1 to 8, the entire inner surface of the plate body 1 is covered.

In the embodiments shown in FIGS. 1 and 8, the plate main body 1 is completely free of dirt during cooking, and only the cooking sheet 8 needs to be cleaned after use, which is extremely convenient.

Therefore, it is sufficient to simply apply anti-corrosion treatment to the plate body 1, and there is no need to perform an expensive self-cleaning treatment or the like.

Incidentally, if tongue pieces projecting outward from the plate main body 1 are formed on the outer peripheral edge of the cooking sheet 8 in FIG. 1 and the outer peripheral edge of the shape-retaining frame 11 in FIG. , the cooking sheet 8 can be easily taken out.

Further, in the embodiment shown in FIG. 8, if the cooking sheet 8 and the shape-retaining frame 11 are made separable, the shape-retaining frame 11 will not get in the way when cleaning the cooking sheet 8, and the cooking sheet 8 can be easily cleaned.

Furthermore, it will be more desirable if the surface of the shape-retaining frame 11 is subjected to non-adhesive treatment such as fluororesin coating.

The embodiments shown in FIGS. 9 and 10 use a clamping body that holds the outer peripheral edge of the cooking sheet 8 between the plate body 1 and the cooking sheet 8 as a shape retaining means for keeping the cooking sheet 8 in a tensioned state. It is.

In FIG. 9, a sandwich body 13 is formed into an annular shape using a heat insulating material, and a protrusion 14 is formed over the entire circumference of the lower surface of the sandwich body 13, and the protrusion 14 of this sandwich body 13 is used for cooking. The groove 15 on the upper end surface of the outer peripheral wall of the plate body 1 is inserted through the outer peripheral edge of the sheet 8.
By fitting into the plate body 1 and the sandwiching body 13, the outer peripheral edge of the cooking sheet 8 is held between the plate body 1 and the sandwiching body 13, and the sheet 8
is applied to the entire inner surface of the plate body 1 and kept in tension.

On the other hand, in FIG. 10, two arc-shaped clamping bodies 13 are provided, and the outer peripheral wall of the plate body 1 and the clamping bodies 1 are connected between the handles 4 and 4.
3.13, the outer peripheral edge of the cooking sheet 8 is held between them.

Therefore, in both embodiments, the cooking plate body 1
You can cook in good condition without soiling the cooking sheet 8 or causing the cooking sheet 8 to move or wrinkle, and after use, you can remove the clamping body 13 and remove the cooking sheet 8. It is only necessary to wash the removed Dharma sheet 8.

Incidentally, since the clamping body 13 is located on the outer periphery of the plate body 1 and is made of a heat insulating material, it functions as a guard to prevent burns.

In the embodiment shown in FIG. 11, the plate main body 1 is divided into left and right parts and folded up when not in use for convenience in storage and storage.

A plate main body 1 is constructed by connecting a pair of plate components 1', 1', which are provided with legs 16 that also serve as handles and have a heating element 2 embedded therein, so as to be openable and closable using hinges 1γ, 1γ,
