Abstract

PURPOSE:To easily remove fouls attached on the inner wall of a compartment by laminating a fluororesin film on an inner plate. CONSTITUTION:An inner pate 8 made of aluminized steel plate is attached on the inner side wall of an inner box 2. A transparent, non--adhesive and non-combustible fluororesin film 9 is attached on the inner face of the inner plate 8. Therefore, if oils, etc., attach on the surface of the inner plate 8, they can be easily wiped off, and also it can be prevented that the heat radiated from an upper heater 6 and a lower heater 7 is absorbed and the thermal efficiency drops, causing the cooking time period to be extended. And, as the fluororesin film 9 has a limit in thermal durability, the heater is used while the temperature is controlled by an over-heating preventive device 10. To attach the fluororesin film 9 on the inner plate 8, the tubular fluorine resin film 9 is put over the rectangular inner plate 8 and thermally shrinked so that the film 9 is attached tight on the front and back faces of the inner plate 8.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cooking device such as a toaster oven used in general households, and a method for manufacturing the same.

Conventional technology In recent years, toaster ovens have been used not only for their main function of roasting, but also for a variety of purposes such as pizza, gratin, and oil-cooked foods, and the inside of the oven is easily soiled by oil from the food, so there are expectations for prevention of stains. is increasing.

Conventional cooking devices of this type generally have a configuration as shown in Japanese Utility Model Publication No. 62-6414.

The configuration will be explained below with reference to FIG. As shown in the figure, an upper heater (not shown) and a lower heater 3 are disposed on the side wall of an inner ring 2 forming a cooking chamber 1, and food to be cooked is placed on a food placing table 4 installed inside the cooking chamber 1. (not shown) is placed on top for cooking. A surface treatment plate 6 having a self-cleaning function is installed on the inner surface of the inner casing 2 to deal with dirt that has accumulated inside the cooking chamber 1.

Problems to be Solved by the Invention In such a conventional cooker, if a surface-treated plate 6 having a self-purifying function is installed on the inner surface of the inner casing, There was an issue with time being slow. This is because a material with relatively excellent heat absorption such as manganese dioxide, zinc-manganese ferrite, and aluminosilicate salt is used as a surface treatment substance that has a self-purifying function. This is because the heat absorbed by the surface-treated plate and, as a result, absorbed by the food to be cooked is apparently reduced.

The present invention solves the above-mentioned problems, and provides a cooking device that does not impair efficiency, does not slow down cooking time, and can easily remove dirt from the inside of the cooking chamber.
The purpose is to provide an easy manufacturing method.

Means for Solving the Problems In order to achieve the above object, the present invention has as a first means a cooking cabinet equipped with a heater, and an inner plate provided on the inner surface of an inner casing forming the cooking cabinet. The second method is to cover the inner plate with a tube-shaped fluororesin film, heat shrink it, and attach it to the inner plate. It is something.

Function The present invention provides a cooking chamber with an inner plate protected with a fluororesin film as described above, so that the fluororesin film has low heat absorption, so there is less heat reflection loss inside the cooking chamber. Oil adhering to the surface of the required inner plate can be easily removed.

Furthermore, since the tube-shaped fluororesin film is placed over the inner plate and then heat-shrinked, the work of attaching the fluororesin film to the white board can be done easily.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 and 2. Note that the same components in the conventional example will be described with the same reference numerals.

As shown in FIG. 1, an upper heater 6 and a lower heater 3 are disposed on the side wall of the inner casing 2 forming the cooking chamber 1, and the upper and lower heaters 6.3 are used to cook food placed on the food cutting table 4. I try to cook item 7.

An inner plate 8 made of an aluminized steel plate or the like is attached to the inner surface of the inner case 2. Furthermore, the inner surface of the inner plate 8 is coated with a transparent, non-adhesive, and nonflammable 7-carbon resin film 9.

With the above-described structure, even if oil or the like falls off from the food 7 and adheres to the surface of the inner plate 8 during cooking, the inner plate 8 is covered with a non-stick fluorine resin film 9. Because it is a dress,
Can be easily wiped off.

In addition, since the inner plate 8 is covered with a transparent fluororesin film 9, the upper heater 6 and lower heater 3
It also does not slow down cooking time by absorbing heat radiated from the oven and reducing thermal efficiency.

Further, at this time, since the fluororesin film 9 has a limited heat resistance, an excessive temperature rise prevention device 10 is attached to the film while controlling the temperature. In addition, by doing this, the extent to which oils and the like that have spattered from the cooking items can be scorched is also suppressed, and it becomes easier to wipe them off.

In addition, as shown in Fig. 2, the fluororesin film 19 is attached to the inner plate 8 by first covering the tubular fluororesin film 9 along the shape of the approximately rectangular inner plate 8 as shown in Fig. B). Then, by heat shrinking, the inner plate B is brought into close contact with the front and back sides of the inner plate B, as shown in 1χtp), and then attached. In this way, it can be removed cleanly and easily with simple equipment.
It is something that can be done.

Effects of the Invention As is clear from the above embodiments, the present invention comprises a cooking chamber equipped with a heater and a white plate provided on the inner surface of an inner casing forming the cooking chamber. Since the inner plate is coated with a fluororesin film, even if oil etc. splashes out from the food during cooking and forms a layer on the surface of the inner plate, it can be easily wiped off, and especially removes waste emitted from the heater. It will not absorb and slow down the cooking time.

Furthermore, the fluororesin film can be made into a tube and placed over a white board and heat-shrinked to adhere tightly to the white board, thereby providing a highly productive manufacturing method.
