CONSTITUTION:In a box-like toaster which uses a bar-like far infrared radiation ceramic heaters 2, 3 as heat sources, the far infrared radiation ceramic heaters 2, 3 comprise reflecting plates 7 which rotate around the longitudinal axis of the respective heaters 2, 3 such that the angular velocity of the rotation of the reflecting plates 7 can be varied and are arranged relative to the far infrared radiation ceramic heaters 2, 3 respectively.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toaster for toasting bread and the like.

[0002]

2. Description of the Related Art In recent years, with the gourmet boom, consumers are increasingly interested in genuine tastes.

FIG. 3 is a front view for explaining a conventional toaster. Reference numeral 1 denotes a front panel of the toaster body, which is provided with a changeover switch 4 for turning on / off the power of the far infrared ceramic heaters 2 and 3 provided inside the body, and a timer 5 for setting an energization time. Further, 6 is a table provided in the main body, on which the far infrared ceramic heaters 2 and 3 are attached.

The conventional toaster is constructed as described above. When the pan is placed on the table 6 and the timer 5 is set and the power is turned on, the pan is radiated by the far infrared ceramic heaters 2 and 3. Is baked as toast.

[0005]

In general, an ideal delicious toast is a toast having a thin surface of a baked surface of, for example, about 0.8 to 1.0 mm and a high internal temperature of about 5% or less of moisture attenuation. It is said that there is.

Therefore, in order to raise the internal temperature, it is effective to use a far-infrared ceramic heater as a heating source because the organic substance such as food can be absorbed very well without heating the air to heat the inside.

Further, in order to bake in a short time while suppressing the decrease of water content, far infrared ceramic heaters 2 and 3 as a heating source are used.
It is conceivable to increase the amount of heat to bring the table 6 closer to the table 6, but if it is brought too close to the table 6, uneven burning will occur in the conventional toaster configuration.

Further, as another problem of conventional toasters, when the amount of heat of the heating source is increased, the temperature inside the toaster becomes extremely high, and when the baked toast is left as it is, there is a drawback that it is overbaked by residual heat.

It is an object of the present invention to provide a toaster capable of baking a delicious toast in a short time while eliminating the above problems in the conventional toaster.

[0010]

According to the present invention, in a box type toaster using a rod-shaped far infrared ceramic heater as a heat source, the far infrared ceramic heater is rotated about its longitudinal axis. In addition, a far-infrared reflecting plate formed so that the angular velocity of its rotation can be changed is arranged.

[0011]

According to the present invention, the far infrared rays radiated from the far infrared ceramic heater are directly radiated to the bread of interest and also radiated and heated by the far infrared rays which are condensed and reflected by the reflector. At that time, at a location far from the far infrared ceramic heater, since the focal length of the reflection plate is constant, the converging area of the reflected light expands, and a difference occurs in the thermal energy received per unit of toast, resulting in uneven heating. , It is improved by rotating the reflector plate immediately below the far infrared ceramic heater and slowly rotating it as it gets farther from the far infrared ceramic heater. The toast will be baked in a short time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a toaster according to an embodiment of the present invention. Reference numerals 1 to 6 are the same as those in FIG. 3, and other reference numerals, 7 is a reflection which is a feature of the present invention. It is a plate.

The reflection plate 7 is provided above and below the far-infrared ceramic heaters 2 and 3 so that the center of the rotation axis is substantially on the center of the far-infrared ceramic heaters 2 and 3 and is rotatable. Further, it is provided with a variable angular velocity mechanism (not shown) capable of controlling the rotation angle.

FIG. 2 is a side sectional view for explaining the operation of FIG.

Far-infrared rays emitted from the far-infrared ceramic heaters 2 and 3 directly heat a loaf of bread (not shown) placed on the table 6, and at the same time, the loaf of bread is indirectly reflected by the reflector 7. Is also heated by.

The variable angular velocity type reflection plate 7 sets the focal length of the reflection plate 7 so that the far infrared rays from the far infrared ceramic heaters 2 and 3 are focused on the surface of the table 6 immediately below the surface of the bread. I'll do it. Then, by rotating the reflection plate 7, the indirect light 8 is spread over the entire surface of the bread. At this time, the far infrared ceramic heaters 2, 3
Since the focal length of the reflection plate 7 is constant at a long distance, the condensing area 9 of the indirect light 8 is expanded, and uneven heating occurs.

Therefore, in order to rotate the reflecting plate 7, it is fast just below the far-infrared ceramic heaters 2 and 3 of the bread, and slowly as the distance increases.
Far-infrared rays uniformly hit the entire bread surface. That is, if the rotational angular velocity of the reflection plate 7 is variably controlled, a delicious toast that is uniformly irradiated with far infrared rays and has no unevenness in baking is baked in a short time.

A toaster using a halogen lamp having a sharp rise can be considered as a heating source, but in that case, the halogen light itself has a poor absorption property for organic substances such as foods, and radiates far infrared rays on the surface of the halogen lamp. ,
It has to be dealt with by coating a ceramic such as Al ₂ O ₃ , SiO ₂ , Li ₂ O or by putting it in a plate shape and placing it on the front surface of the halogen lamp.

[0020]

As described above, in the toaster of the present invention, the far-infrared ceramic heater is provided with the variable angular velocity type reflection plate, and the far-infrared rays are uniformly irradiated on the front surface of the bread, so that it can be performed in a short time. There is an advantage that uneven baking is not caused and overburning can be reduced, and delicious toast with a thin surface layer on the baking surface can be baked.
