Description

[Detailed explanation of the invention] <Industrial application field> This invention is a method for baking bread that is cut in half to insert ingredients (hereinafter referred to as buns) when selling breads such as hot dogs and hamburgers in stores. The present invention relates to a toaster suitable for.

<Prior art> In general, the deliciousness of bread that is eaten by putting ingredients inside the bread, such as hot dogs, depends on how well the bread is baked. The flavor of the bread is greatly affected by whether it is sufficiently baked. By the way, in the past, when making hot dogs, etc., the buns were generally baked using an electric or gas oven, and there was no special equipment for baking the buns.

<Problems that the invention aims to solve> As mentioned above, it is a simple operation because you can simply bake the buns in an oven, etc., but since the buns are baked from the outside, the inside cannot be fully baked.
Furthermore, since only the area near the heat source is heated, only the surface of the bread, such as a hot dog, is burnt, while the inner part is not heated enough, and the overall baking is not even.

The present invention has been made to improve these points, and aims to provide a toaster that retains moisture in the buns and toasts the buns uniformly to the inside without drying them.

<Means for Solving the Problems> The toaster for hot dogs and other buns according to the present invention includes a box-shaped case, and a far-infrared ray-emitting ceramic planar heating element unit installed under a window hole provided in the top plate of the case. , a toaster body consisting of an aluminum hot plate for placing buns attached to the window hole of the top plate and having a ceramic surface; and a top lid covering the toaster body; It is characterized by the addition of a manufactured far-infrared reflector.

That is, by taking advantage of the fact that far infrared rays are well absorbed by water, flour, etc., far infrared rays are radiated onto the buns from all directions so that the buns are evenly heated to the inside.

An embodiment of the present invention will be described based on a front view in FIG. 1 and a side view in FIG. The case 2 of the toaster main body 1 is a box made of a metal plate such as a stainless steel plate, and the ceiling surface is constituted by a top plate 3 having a square window hole in the center. A ceramic planar heating element unit 4 is suspended below the window hole on the lower surface of the top plate 3 and is fixed via a heat insulating material 5 such as alumina fiber, and the heat rays from the planar heating element unit are radiated upward through the window hole. be done. As the ceramic planar heating element unit, a composite panel is used in which a composite ceramic plate made of silicon nitride, silicon carbide, iron oxide, or the like is laminated on the top surface of the planar heating element. The hot plate 6 for placing buns is fixed on the top plate 3 to form the toaster body 1, having a width appropriate to the periphery of the top plate and maintaining an appropriate height from the ceramic planar heating element unit 4. are doing. In this example, in order to increase the radiation efficiency of far-infrared rays, this hot plate for placing buns has its surface anodized and made into ceramic with Al ₂ O ₃ , and the surface is coated with a non-containing material such as a fluororesin coating. It is coated with an adhesive film. In addition, the shape of the hot plate is such that the partition walls of the adjacent parts are formed in a mountain shape with an apex angle of about 60° so that the cut-out buns such as hot dogs can be lined up effectively. It's okay to be.

The upper lid 7 is box-shaped, and the lower edge of the back surface is connected to the rear edge of the toaster main body via a hinge, so that it can be opened and closed to cover and seal the toaster. A handle 9 is attached. A far-infrared reflecting plate 8 is attached to the entire inner surface of the upper lid 7. In this example, in order to increase the radiation efficiency of far-infrared rays, the far-infrared reflector was anodized and the surface was coated with Al ₂
An aluminum plate ceramicized with O ₃ is used.

In addition to the above-mentioned methods, methods for ceramicizing the surface of the sheet heating element, the bun-mounting hot plate, and the far-infrared reflector include AlN, TiO ₂ ,
A ceramic film may be formed by coating, spraying, or anodizing a metal oxide with high far-infrared radiation efficiency, such as ZrO ₂ or Al ₂ O _3. In short, when the sheet heating element is energized, it will emit far infrared radiation. It is only necessary to have a structure that emits or reflects infrared rays, and there is no need to specify a method for forming the film.

Although not shown, it is possible to install a timer or the like in the electrical circuit of the sheet heating element to set the energization time, or install a thermostat to set or control the temperature of the sheet heating element. It is similar to a normal oven, and the power switch, operation switch, indicator lamp, etc. are built into the front panel of the toaster body.

<Function> In use, all you have to do is place the buns on the bun-placing hot plate on the case body, close the top lid, and energize the planar heating element. The far infrared rays emitted from the ceramic sheet heating element pass through the window hole in the top plate to heat the bun-mounting hot plate, and are re-irradiated by a reflector attached to the entire inner surface of the hot plate and top lid, thereby heating the buns. Contributes to heating.

Far-infrared rays are well absorbed by water, flour, etc., so the entire bun is evenly heated to the inside.
In addition, far-infrared heating prevents moisture from evaporating more than necessary, and the surface of the buns will not become black or dry and hard. Therefore, it can be baked quickly. Furthermore, even if the buns are placed randomly on the hot plate, they will all be baked uniformly and beautifully.

When a 600W ceramic sheet heating element unit is used as a toaster according to the present invention,
In just seconds, the surface of the buns was baked to a golden brown color, and the inside temperature was evenly raised to nearly 60 degrees Celsius without drying out the buns.

In conventional ovens with electric heaters, only the surface of the buns is heated, and in order to avoid burning, it is necessary to take a long time to bake the buns, which takes 70 to 80 seconds. With the toaster according to the invention, the baking time can be halved and a beautiful toasted state can be obtained.

<Effects of the invention> The toaster of this invention irradiates the buns with far-infrared rays from the top and bottom, left and right, and front and back directions, so the buns are heated evenly and quickly to the inside, and are kept clean without becoming overly dry. It can be baked. Furthermore, when using the device, it is possible to simply place the buns on the hot plate for placing the buns and turn on electricity, and no skill is required and the device has the advantage of being easy to use.
