Abstract

PURPOSE:To improve a performance of baking distribution and an efficiency of energy in a home-use oven toaster by a method wherein a baking net is rotated between an upper heater and a lower heater hang on side walls of an inner casing and the upper and lower heaters are moved in an upward direction and a downward direction. CONSTITUTION:Side walls of an inner casing 12 forming a cooking chamber 11 are provided with an upper heater 13 and a lower heater 14 which can be moved in a vertical direction. A baking net 16 arranged between the upper heater 13 and the lower heater 14 is cooperated with a motor 20 and can be rotated around a rotary shaft 17. So, approximate half part of a cooked item 18 is baked up substantially in a uniform manner by the upper heater 13 and the lower heater 14, resulting in that the cooked item 18 may also be rotated together with a rotation of the baking net 16 and thus an entire cooked item 18 can be uniformly baked. Since the upper heater 13 and the lower heater 14 can be moved in a vertical direction, cooking other than toasting can be easily and efficiently performed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a toaster oven for general household use.

BACKGROUND OF THE INVENTION A conventional toaster oven of this type was developed, for example, in the 1980s.
As shown in Japanese Patent No. 25816, it had a structure as shown in FIG.

That is, the upper and lower heaters 3 and 4 are suspended on the side wall of the inner casing 2 that forms the cooking chamber 1, and the grill 6 is movable back and forth between the upper and lower heaters 3 and 4 in conjunction with the opening and closing of the door 6. It is mediated by Then, the food 7 is placed on the gridiron 6 and heated and cooked.

Problems to be Solved by the Invention In such a conventional configuration, the food 7 is easily burnt near the center near the lower heater 4 due to the extremely strong radiant heat and convection. In order to evenly bake the food 7, it is necessary to provide an inclined surface 8 directly below the lower heater 4, which disperses the radiant heat of the lower heater 4 to the front and rear ends of the food 7, and to Lower heater 4
A heat shield plate 9 had to be installed between the two to block radiant heat and convection. In addition, for the upper surface of the food 7 where such a structure is difficult to implement, the reflective plate 1o forming a part of the inner casing 2 is bent in multiple stages to disperse radiant heat to the front and rear ends of the food 7. The structure was such that it baked evenly. For this reason, not only does the structure become extremely complicated, but the energy efficiency is very poor because the radiant heat and convection from the heater are blocked or dispersed, and the radiant heat directly below the upper heater 3 is not very effective. In order to weaken the effect, it was necessary to provide a larger spatial distance than necessary. In addition, the upper and lower heaters 3, 4
The balance of power consumption is set so that the toast is baked evenly from top to bottom, so if you use a saucer other than toast, or if you are cooking frozen foods, you may need to use a diode or microcontroller, for example. They used this to adjust the balance of power consumption between the upper and lower heaters for cooking by changing the energization rate.

The present invention solves these problems, and aims to provide a toaster oven that cooks well, saves space, has a simple shape, and is highly energy efficient. .

Means for Solving the Problems In order to solve the above problems, the present invention provides an inner casing forming a cooking compartment, upper and lower heaters suspended on the side walls of this inner casing, and a space between the upper and lower heaters. Equipped with a grill placed in the
The grill grate is rotated and the vertical heater is movable in the vertical direction.

Function According to the above configuration, as the grill is rotated, the food placed on the grill is also rotated. Therefore, if the upper and lower heaters are set so that half of the food can be baked almost uniformly, the entire food can be baked evenly by rotation. In addition, since the upper and lower heaters can be moved vertically as the grill rotates, it is possible to easily and efficiently cook foods other than toast at a low cost.

EXAMPLE Hereinafter, an example of the present invention will be described based on the accompanying drawings. In FIGS. 1 and 2, 11 is a cooking cabinet, 12 is an inner casing forming the cooking cabinet 11, and 13 and 14 are inner casings 12.
16 is a door that opens and closes the front of the cooking cabinet 11; 16 is a grill; 17 is a rotating shaft installed in the center of the grill 16; 18
is a cooking item, and 19 is a saucer. In addition, the upper and lower heaters 1
3.14 About half of the cooked food 18 is baked almost evenly. In addition, the grill 16 is connected to the motor 2o.
The rotary shaft 17 can be rotated in conjunction with the rotary shaft 17. The rotating shaft 17 rotates 6 to 6 times per minute. With such a configuration, the upper and lower heaters 13 and 14 only allow about half of the food 18 to be baked almost uniformly, and the food 18 also rotates with the rotation of the grill 16, so that the food 18 can be cooked evenly. The entire object 18 can be baked evenly. Therefore, according to the configuration of the present invention, in order to uniformly bake the whole food as in the past, the radiant heat is dispersed or blocked, the reflective part is bent more, and the radiant heat directly under the upper heater is heated. There is no need to create more spatial distance than necessary to weaken the influence of
It can be space-saving, simple in shape, and highly energy efficient. In other words, since a uniform roasting distribution can be easily obtained, it is possible to achieve a higher wattage than before, and also to significantly shorten the cooking time, which can be expected to have great effects in terms of both grilling distribution performance and efficiency.

Since the upper and lower heaters 13 and 14 are still movable in the vertical direction, it is possible to use the saucer 19 as shown in Figure 2 for cooking, frozen cooking that requires thawing, or when the thickness of toast changes. This can easily be used for cooking that requires adjustment from the balance of power consumption of the upper and lower heaters when roasting six pieces of toast. For example, saucer 1
9, when the upper and lower heaters do not move, the balance of power consumption during toast roasting is such that the influence of the upper heater 13 on the food 21 is lower than that of the lower heater 14 due to the use of the saucer 19. It is stronger than the influence of
When the front side of the food 210 is browned and ready to be cooked, the back side and inside are not yet cooked. Conventionally, the solution to this problem was to adjust the balance of power consumption between the upper and lower heaters using diodes, etc. to enable cooking other than toast roasting. Since the grilling distribution during grilling can be easily obtained, the distance between the heater and the food to be cooked can be brought closer than in the past, and higher wattage can be achieved, so the influence of the upper and lower heaters on the food to be cooked is greater than in the past. For this reason, if a diode is connected in series to the upper heater 13 and the power consumption of the upper heater 13 is reduced by half, the influence of the lower heater 14 on the food 21 will be stronger, There may be cases where the food cannot be cooked properly, and in the case of a rotating grill type, cooking may not be possible with just the use of diodes.

In addition, in the movement of the upper and lower heaters 13 and 14, in the conventional method in which the grill does not rotate, in order to bake the food evenly, an inclined surface is provided directly below the lower heater, and the upper part of the upper heater is placed in an inner casing. Since the reflector, which forms part of the body, is formed by folding it into multiple stages, moving the heater up and down changes the positional relationship between these and the heater, which greatly reduces the thermal distribution performance. This grate rotation method has a simple shape and excellent grilling distribution performance, so
Even if the upper and lower heaters 13 and 14 are moved, the grilling distribution performance does not change, and therefore it is possible to cope with cooking other than toast more easily and efficiently than when using diodes or the like.

Effects of the Invention As is clear from the description of the embodiments above, the toaster oven of the present invention has an inner casing forming a cooking compartment, upper and lower heaters suspended on the side walls of this inner casing, and a space between the upper and lower heaters. Since the grille is configured to be rotatable and the upper and lower heaters are movable in the vertical direction, the food placed on the grille is controlled by the upper and lower heaters. By simply baking half of the food almost uniformly, the rotation of the grill also rotates the food, so the entire food can be baked evenly. Therefore, in order to uniformly bake the entire food as in the past, radiant heat has to be dispersed or blocked.
There is no need to bend the reflective part a lot or create more space than necessary to weaken the effects of radiant heat directly under the upper heater, saving space, simplifying the shape, and improving thermal distribution performance.

It is possible to provide a toaster oven with extremely high energy efficiency.

However, since the upper and lower heaters are configured to be movable in the vertical direction, it is possible to easily and efficiently cook foods with excellent toast distribution performance even when cooking other than toast roasting, without using diodes or microcontrollers. Moreover, the product can be manufactured at low cost. Furthermore, in ancient times, it has been said that "high heat and distant heat" is good for cooking pottery, but according to the structure of the present invention, the heat is repeatedly increased and decreased due to the heating of the high-temperature heater and the rotation of the food. Although it is not yet available, sensory test results have shown that it can achieve the same effect as the above-mentioned high heat and distant heat, and can make the food delicious.
