Abstract

PURPOSE:To enable an unstable container to be placed under a stable condition, restrict an influence of heating of the heater to a minimum value and facilitate an adjustment of distribution of high-frequency wave by a method wherein a group of grids is arranged on substantially the same plane in such a way as it may be crossed at least near the central part of the group of grids arranged in parallel on the plane. CONSTITUTION:A group of grids A of a grill 1 is directed laterally toward a front face of a main body and a group of grids B is vertical direction is added near the central part of a forward or rearward direction of the grill. With this arrangement, even in case that unstable container such as rice bowl, glass cup, etc. having a high level of center of gravity is placed on the baking net, it is placed on the group of grids B, the container can be placed under a stable condition without being loosened. Since the small container etc. is only placed on the added group of grids B, the position of the container can be set and thus it is highly efficient when a distribution of the high-frequency wave is to be determined. When the grill 1 is to be used, it is placed just above the lower heater 2, the central part of the bread etc. can be prevented from being highly baked under a influence of the lower heater 2.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a high frequency heating device that heats an object using a grill.

BACKGROUND OF THE INVENTION Conventional grills for toaster ovens and the like generally have a wide grid pitch a and are wavy in order to reduce the influence of the grill when toasting toast, as shown in Figure 3. It is shaped like this.

Problems to be Solved by the Invention However, when the grating has a wide grid pitch or a wavy shape as described above, it is difficult to place objects with small bottoms and high centers of gravity, such as rice bowls and glass tops, on the grate during high-frequency heating. If you use it, it will be unstable and difficult to place, and it will easily fall over due to vibrations caused by opening and closing the door.

The present invention solves these conventional problems, and makes it possible to store containers in a stable state without tipping over even when using unstable containers with high centers of gravity, and also to make it easier to heat them with a heater. This minimizes the influence of the grill and makes it easy to adjust the distribution during high-frequency heating.

Means to Solve the Problem The high-frequency heating device of the present invention includes a heating chamber that stores and heats food in a main body, a high-frequency generator that radiates high-frequency waves into the heating chamber, and a high-frequency generator that increases the ambient temperature within the heating chamber. It consists of a heating device and a grid on which the object to be heated is placed in the heating chamber, and the grid is provided with a first parallel grid group on a plane,
A second lattice group is provided at least near the center, intersecting the first lattice group and substantially on the lower surface of the arm.

Function: The high-frequency heating device of the present invention has a grating group provided in parallel on a plane, and a grating group substantially on the same plane so as to intersect at least near the center. Even when placed on a grill, it can be placed in a stable state without falling over, and small containers etc. can be positioned.

EXAMPLE Hereinafter, a high frequency heating device according to an example of the present invention will be explained with reference to the drawings. As shown in FIG. 1a, the grating group A of the gridiron 1 is oriented horizontally toward the front of the main body, and a vertical grating group B is added near the central portion of the grilling grid in the front-rear direction. In Figure 1, a circular grid group B is arranged vertically. In Figure 1C, a circular grid group B is added from the center of the gridiron 1. In this way, even when an unstable container with a high center of gravity such as a rice bowl or glass top is placed on the gridiron 1, it can be placed on the grid group B in a stable state without wobbling. Also, small containers etc. can only be placed on the added grid group B, so the positioning of the container will be a problem, and the design will improve the high frequency distribution of the added grid group, so the high frequency distribution It is also very useful when making decisions.

In addition, as shown in Fig. 2, when the lower heater 2 is located approximately at the center in the front-rear direction toward the front of the main body and is distributed linearly in the left-right direction, When using 1, it is located directly above the lower heater 2, so when using it as an open toast, it eliminates the problem of the center of the toast being strongly burnt due to the influence of the lower heater 2. I'll give it to you.

゛Effects of the Invention As described above, the high-frequency heating device of the present invention adds a new grating group to the grating group provided in parallel on the plane of the grill so that it intersects at least near the center. As a result, you can obtain the following effects.

(1) Even unstable containers with a high center of gravity can be used in a stable state without wobbling by placing them on the added grid group.

? ) Containers, food, etc. will be placed on the added grid group, so the positioning and distribution during high-frequency heating will be better if designed so that it is better near the center, so please be very careful when designing. This is advantageous and greatly helps improve design efficiency and shorten design time.

0) If the lower heater extends horizontally towards the front of the main unit and is distributed directly above the lower heater, when toasting, it absorbs the heat radiation from the lower heater and makes the toast. This solves the problem of the center being too strong and overcooked.

4) One grill can be used for both high frequency heating and heater heating, resulting in cost reduction.
