Abstract

PURPOSE:To facilitate a looking-at of an interior of an oven housing and eliminate any trouble even if oily smoke is generated by a method wherein a quartz heater is applied and this quartz heater is covered by a uniform heating plate provided with some slits. CONSTITUTION:A quartz heater 10 lights at a color temperature higher than 1,000 deg.C as it is electrically energized and an interior or a cooking housing 6 is illuminated bright with light leaked out of slits 13. In turn, since the quartz heater 10 is almost shielded by a uniform heating plate 14, a light from the quartz heater 10 does not enter directly into an eye (a), resulting in that an interior of the cooking housing 6 may easily be seen and an amount of heat leaked out of the oven through a door 4 is reduced. In addition, a radiation heat with a high radiation intensity got from the quartz heater 10 is received by the uniform heating plate 14 and at the same time it is metered to an appropriate radiation calories with slits 13 and thus the cooked item 9 is uniformly heated with a secondary radiation heat and the convection heat. In addition, the oily smoke dispersed during a cooking operation is almost shielded by the uniform heating plate 14 and merely reaches a surface of a quartz tube 11 through slits 13 only in a quite small amount, so that the quartz tube 11 is not peeled off or cracked due to a phenomenon of loosing sight.

Description

[Detailed description of the invention] Industrial applications The present invention relates to an electric roaster.

BACKGROUND ART In a conventional electric roaster, a sheathed heater 21 was used, as shown in FIG.

Problems to be Solved by the Invention However, since the conventional pottery device 20 uses a sheathed heater 21, the startup speed is slow and the energy radiation intensity is low, making it impossible to obtain appropriate baking conditions. Since the temperature of the cooking chamber 21 was around 650° C., the inside of the cooking chamber 22 was dark and it was difficult to see the cooking status. In order to solve this problem, if we adopt a quartz heater (filled with halogen gas, etc.) that raises the color temperature of the stove to over 1000°C, the energy radiation intensity will increase and the cooking area 22
The inside of the cooking cabinet becomes brighter, but the brightness of the quartz heater, which has a color temperature of over 1000 degrees Celsius, is dazzling when looked at directly, making it difficult to see inside the cooking cabinet.゛Also, if a large amount of oil smoke scattered during cooking adheres to the quartz heater, the salt contained in the oil smoke, especially Na, will react with the quartz tube of the quartz heater, causing a so-called devitrification phenomenon, leading to peeling and cracking. There was fear.

The object of the present invention is to solve the above-mentioned problems and provide an electric griller that allows the inside of the cooking oven to be easily seen during cooking and that does not cause problems due to the generation of oily smoke.

Means for Solving the Problems In order to solve the above problems, the present invention employs a quartz heater and covers the quartz heater with a heat equalizing plate provided with slits.

Effect With the above configuration, if the quartz heater is energized, 100
Since it glows with a color temperature of 0°C or higher, the light leaking through the slits in the heating plate brightly illuminates the inside of the cooking cabinet.

In addition, by shielding the front of the quartz heater with a heat equalizing plate, the light from the quartz heater will not directly enter your eyes, making it easier to see inside the cooking chamber, and reducing the amount of heat escaping through the door, improving efficiency. In addition, when heating the food to the maximum of the radiant heat of the quartz heater, which has high radiation intensity, the area directly below it will be overcooked, but it is better to adjust the slit width of the slit provided on the heating plate. The amount of radiant heat can be narrowed down to a certain amount, and heating can be done evenly by secondary radiant heat from the heat soaking plate and convection heat. Furthermore, most of the oil smoke that scatters during cooking is blocked by the soaking plate, and only a very small amount reaches the surface of the quartz tube, eliminating the possibility of peeling or cracking due to devitrification.

Example Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

Fig. 1 is a cross-sectional view of the main parts of the pottery pottery section showing an embodiment of the present invention, the second figure is a side cross-sectional view of the pottery pottery section and its vicinity, and Fig. 3 is a side cross-sectional view of the pottery pottery section and its vicinity. The front sectional view and FIG. 4 are perspective views showing a sink in a system kitchen in which the pottery section is provided. As shown in FIG. 4, a sink 1 in a system kitchen is provided with a top heater section 3 in which a plurality of spiral sheathed heaters 2 are provided on the upper surface. , a pottery section 5 with a door 4 provided on the front is disposed. As shown in FIGS. 2 and 3, the key 8 that constitutes the pottery section 5! Warehouse 6
Inside, a water tray 7 and a grill 8 placed on the water tray 7 are provided at the lower part, and the food 9 to be cooked is placed on the grill 8. In the upper part of the cooking chamber 6, a plurality of quartz heaters 10 are arranged in parallel, each of which is constructed by sealing tungsten or a heating wire as a heater 12 in a quartz tube 11 together with argon gas or halogen gas. Each quartz heater 10 is covered with a heat equalizing plate 14 provided with slits 3, as shown in FIGS. 1-v and 3.

Here, the slit 13 is formed by cutting and bending. In addition, as shown in FIG.
and a circuit section (not shown) for controlling power to the sheathed heater 2).

Next, the operation of the pottery section 5 in the above configuration will be explained.

First, the door 4 of the pottery section 5 is opened, a predetermined amount of water is poured into the water tray 7, and the grilling grate 8 is set in the water tray 7. After placing the food 9 on the gridiron 8 and closing the door 4, the user operates the operation section 15 to start supplying electricity to the quartz heater 10 of the grill section 5.

When energized, the quartz heater 10 emits light with a color temperature of 1000° C. or more, and the light leaking from the slit 13 makes the interior of the cooking cabinet 6 brighter than +i. On the other hand, quartz heater 1
0 is almost shielded by the heat soaking plate 14, so
The light from the quartz heater 10 does not directly enter the eye a,
The inside of the cooking cabinet 6 is easy to see, and less heat escapes to the outside through the door 4. In addition, the high-intensity radiant heat from quartz 1° is received by the soaking plate 14 and narrowed down to an appropriate amount of radiant heat by the slits 13, so the food 9 is evenly heated by secondary radiant heat and convection heat. heated. moreover,
Most of the oil smoke scattered during cooking is blocked by the soaking plate 14 and only reaches the surface of the quartz tube 1 through the slit 13 formed by cutting and bending. However, it does not cause peeling or cracking due to devitrification phenomenon. Incidentally, when one side of the food 9 is baked, it is turned over and baked in the same manner, thereby completing the 1+I process.

The present invention as described in detail provides the following effects.

(1) Since a quartz heater is used, light with a heater temperature of 1000°C or higher shines brightly into the cooking cabinet through the slits in the heat equalizing plate, making it easier to see the cooking status.

(2) By adjusting the slit width of the heating plate, it is possible to balance the rP:i directly radiated to the food with the secondary radiant heat and convection heat from the heating plate, and uniform heating is possible.

(3) The soaking plate protects the quartz tube of the Fola heater from salt generated during cooking, making it durable for long-term use.

(4) The heat soaking plate protects the quartz heater, which is prone to breakage.
