Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a toaster oven in which bread, pizza, kratan, mochi, etc. are placed on a grill in a heating chamber and cooked by a heating device. .

BACKGROUND OF THE INVENTION FIG. 4 is a side sectional view showing the configuration of a heating chamber and a heating device of a conventional toaster oven. As shown in FIG. 4, in the conventional toaster oven, a heating wire is housed in a heat-resistant insulated pipe at the lower center of an upper wall 22 that forms the upper surface of a heating chamber 21. C), and lower heaters 26 and 27 having the same configuration are provided at the upper center of the bottom wall 25 of the heating chamber 21. In addition, the upper beaters 23 and 24 and the lower heaters 26 and 27 of the h-mouth heat chamber 21
A gridiron 30 on which the object to be heated 29 is placed is supported by the left and right walls 28 (only one side is shown) of the heating chamber 21, approximately in the middle of the heating chamber 21.
is set up.

However, in this type of oven toaster, the heating chamber 2
Since the positions of the upper and lower heaters 23, 24, 26.27 of 1 are fixed, the heating power of the upper and lower heaters 23, 24, 26, 27 can be adjusted depending on the type and quantity of the objects 29 to be heated. The radiant heat from 24, 26, and 27 is shining! The range covered by 8 is limited to 8. In the past, for example, baking two slices of bread required almost the same amount of time as baking four slices of bread, which was extremely inefficient and uneconomical. Furthermore, if you bake bread for a long time, the surface will get browned, and the heat will reach the inside too much, resulting in dry bread with no moisture (moisture) inside. If the bread is not baked for a relatively long time, the temperature in the center will not rise sufficiently, and the result will be unsatisfactory. The structure was not able to adequately handle the amount of food.

The present invention solves these conventional problems,
It is an object of the present invention to provide a toaster oven that has a simple configuration and can exhibit optimum cooking performance depending on the type and quantity of the object to be heated.

Means for Solving and Overcoming the Problems In order to solve the above problems, the toaster oven of the present invention
is one in which at least two of the plurality of heating devices installed on the same plane of the heating chamber are arranged almost parallel to each other, and the distance between the parallel heating devices is variable. It is.

Effect With the above configuration, the distance between the parallel heating devices in the heating chamber can be varied, so the distance between the heating devices can be made smaller to widen the area irradiated with radiant heat, or the distance between the heating devices can be made smaller. This can be done by narrowing the area covered by the radiant heat. Therefore, you can bake bread well in a short time.
- You can also slowly bake batari, gratin, etc. until the heat reaches the center.

Example Embodiments of the present invention will be described below based on the drawings.

Fig. 1 is a partially cutaway side sectional view of a toaster oven showing an embodiment of the present invention, and Fig. 2 is a side sectional view of the toaster oven.
Fig. 3 is a front view of the toaster oven with the door open. As shown in FIG. 3, an object to be heated 6 such as a loaf of bread is placed inside the l-staho body 1 at a heating level of 3! A heating chamber 2 is formed, and in the upper part of the heating chamber 2 there are two heating devices each having a cork-shaped heating element inserted into a heat-resistant insulating pipe made of ceramic or the like. - Extending in the direction of one star body width lj and disposed in parallel. A grill 5 on which food is placed is placed on the bottom of the heating chamber 2, and on the VL grill 5, for example, two slices of bread, which are objects to be heated 6, are placed on the left and right.

A planar lower heater (not shown) is provided below the bottom surface of the heating chamber 2 in the toaster main body 1.

As shown in Figure 1, approximately one side of the upper heaters 3 and 4;
That is, on the upper surface of the heating chamber 2, 1--star body 1 is provided.
A reflector plate 7.8 extending rearward or forward from the front wall 1a or rear wall 1b of the heating chamber 2 and serving as the upper wall of the heating chamber 2, and made of heat-resistant corrosion-resistant stainless steel or the like, covers the upper outer periphery of each upper heater 3, 4. 3. The upper heater is provided so as to cover it. /I reflection efficiency has been increased. Each of the reflecting plates 7 and 8 is divided approximately above each of the upper heaters 3 and 4, and has a fixed portion 7a fixed to the front surface W1a and the rear wall 1b of the toaster main body 1.
, 3a, and a rotation shaft 15. at the end of the fixed portions 7a, 8a.
Movable parts 7b, 8b rotatably attached via 16
It consists of. Support members 9.10 extending vertically are fixed to the ends of the movable parts 7b and 8b on the rotation axis side.
．． The upper heaters 3 and 4 are supported through the lower portions of the supporting members 9 and 10, and a power supply line (not shown) is installed in the lower portions of the supporting members 9 and 10. The upper portions of the support members 9 and 1o are inclined toward the center in the front-rear direction, and elongated holes 9a and 10a are formed in the same shape. A connecting member 11 having protrusions Ha at both ends is disposed between these supporting members 9, 10, and the connecting member 11 has the protrusions 11a inserted into the respective elongated holes 9a, 10a to form the supporting portion U'9. 10 are connected. This connecting member 11 is engaged via a tension spring 14 to the rear end of a heater switching lever 12 which is rotatably supported by a mounting member 17 extending above the front reflecting plate 7 . As a result, by lowering the knob 13 attached to the front end of the heater switching lever 12, each member is rotated in the direction of the arrow, as shown in FIG. 2, so that the parallel open circuit distance of the upper heater 3.4 is narrowed. It has become. Note that 18 is an auxiliary reflecting plate provided above between the reflecting plates 7 and 8. Further, the portion near the upper heater 3.4 of the reflector plate 7.8 has a cross-sectional shape approximating a parabola, so that thermal radiation can be applied almost parallel to the object to be heated.

With the above configuration, the knob 13 shown in FIG.
3. Place the heater in the upper position. Since the parallel distance between /I is set relatively wide, the irradiation range of radiant heat is widened, and it is possible to bake objects such as kratan slowly until the temperature of the center reaches a sufficient temperature, or to heat a large amount of heat. Suitable for cooking heated foods. Also,
In the case of an object to be heated such as bread, by pushing down the knob 13 as shown in FIG.
moves upward, and as a result, the upper parts of the supporting parts 419.10 open to the left and right of each other, and are attached to the lower ends of the supporting members 9.10 (
= The parallel distance between the upper heaters 3 and 4 that are connected by I-C becomes narrower. Therefore, the irradiation range of radiant heat is narrowed, and bread can be baked in a moderate amount of time and in a short time. In either case, the movable portions 7b of the reflectors 7 and 8.

Since 8b is linked to the upper heaters 3 and 4, it is possible to always form and provide a parallel radiant heat distribution to the object to be heated, thereby achieving uniform heating control [q1] without uneven heat distribution. In addition, toheater 3. /l has a structure in which the heating element is housed in a reramic pipe, so when the temperature of the heating element becomes high, an extremely large amount of near-infrared rays are radiated, which efficiently heats objects placed within the radiation range. It's coming. 1 1K d3, knob 13 depending on the type and amount of the object to be heated
Adjust the position of the upper heater 3. 'If you change the distance between the parallels of I, you can get J, or if you select the energization range of the sheet heater for the lower heater, you can get J. Alternatively, the configuration of "-F" may be reversed, or the distance between both heaters may be changed in parallel.

Advantageous Effects As described above, according to the present invention, the following effects can be achieved.

(1) Variable distance between heaters with strong radiant heat.
As a result, the heating power can be adjusted according to the type of object to be heated, and the radiation range of the heater can be appropriately selected according to the quantity, resulting in good thermal efficiency and energy saving.

(2) Since radiant heat can be irradiated over a wide area, the heating chamber can be made sufficiently large and a large amount of heat can be adjusted at once.
