Abstract

PROBLEM TO BE SOLVED: To devise so as to extend uniformly the heat quantity over a food by providing a cooking heater with a driver to move the holder for a subject to be heated up, toward at least one way or two ways of the horizontal and vertical directions in the heating room while heating it. SOLUTION: A grill 14 is to be put into a grillroom 11, and the stays 24 for the grill 14 are then to be set on the receivers 26 of the bars holding a water receiving pan 12. Depressing the ignition switch for grill ignites each burner to turn at the same time a gear 30 reciprocally toward the tow directions by turning a motor in a driver 16, thus reciprocally moving a slide jig 28 toward the horizontal direction via a rack 28A mated with the gear 30. This results in moving the pulleys 20 reciprocally toward the horizontal direction by the grill 14 fixed to the slide jig 28 to heat up the subject food on the grill 14 until a pre-set time is over. This results in making a uniformity of the heat quantity to be added to the subject food. Additionally, a size of horizontal movement vs. the inside size of a grillroom 10 can be determined by a number of ditches made on the rack 28A of the slide jig 28.

Description

Detailed Description of the Invention

[0001]

The present invention relates to a cooking device such as a grill and an oven. In particular, the present invention relates to an improved cooking device for reducing unevenness of baking that occurs in a heated object during cooking.

2. Description of the Related Art Conventionally, heating cookers such as grills and ovens for heating foods to bake them or to make them brown are known. FIG. 6 is a front view schematically showing a double-sided grill which is one of such heating cookers. The double-sided grill shown in the figure is configured with a box-shaped (heating box) 1 as a center, and a Schwank burner 2 for heating is attached to the upper inside of the grill box 1. The Schwank burner 2 is mainly composed of a plate-shaped ceramic plate having a large number of holes formed therein, and the flame of the burner is downwardly projected from the holes.

At the center of the inside of the grill cabinet 1, a grill (heated article support base) 3 on which a heated article is placed is fixed by a support member (not shown) such as a stay. . Also, at the bottom of the grill cabinet 1, there are two Bunsen burners 4
Is attached. In such a state, the above-mentioned Schwank burner 2 of the upper flame (infrared burner) and the Bunsen burner 4 of the lower flame (open flame) burn, so that the heating object 5 placed on the grill 3, for example, Bake fish, etc.

[0004]

However, the double-sided grill described above has a drawback in that the heating object 5 has uneven baking. The cause is that the amount of heat applied to the heating object 5 is not uniform, and there are a portion where the heating amount is concentrated and a portion where the heating amount is small. In particular, since the Bunsen burner 4 of the lower heat is an open fire, the difference in the heating amount is large and the back surface of the heating object 5 has a noticeable uneven burning.

In addition, due to the difference in combustion method between upper and lower fires,
There is also a drawback that the baked state is different between the front surface and the back surface of the heating object 5. This is because the Schwanner burner 2 for the upper heat is an infrared type, so that the combustion surface is wide, the entire area burns in a bonfire state, the flow of the heating amount is relatively uniform, and the uneven burning is small. On the other hand, the lower heat Bunsen burner 4 is in a direct combustion type and therefore has a sharp combustion state. As a result, the flow of the heating amount is likely to concentrate in the center of the heating object 5, and the flow of the heating amount to both ends is Since the amount is small, uneven baking occurs.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a heating cooker capable of cooking food in a uniformly baked state with less unevenness in heating. It is in the place of providing.

[0007]

In order to solve the above problems, a heating cooker according to the present invention comprises a heating cooker, a heated object support table disposed inside the heating cooker, and an inside of the heating cooker. And a burner that heats and cooks the heated material on the heated material support table, the horizontal direction and the vertical direction of the heated material support table in the heating chamber during heating. , And at least one or both of them are provided with driving means. By doing so, it is possible to move the grill on which the food is placed during the heating in the grill cabinet so that the heating amount can be evenly distributed over the food. Therefore, it is possible to reduce the uneven baking of food.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION In the heating cooker of the present invention,
The drive means is configured to include a motor for moving the heated article support table and a position detection device for detecting a position of the heated article support table in the heating chamber, and the position detection apparatus after heating is completed. When it is detected that the position of the heated object support table with respect to the heating chamber reaches the center, the driving of the motor may be stopped.
