Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an improvement in a high frequency heating device having a food hiding function.

2. Prior Art A conventional high-frequency heating device of this type was developed in Japanese Utility Model Publication No. 61-423.
This is proposed in Publication No. 82. In this proposed configuration, the upper heater and lower heater are built into the heating chamber.
When the fixing piece protruding from the bottom of the kneading machine is inserted into the mounting hole provided on the bottom of the heating chamber and rotated by a predetermined angle, the fixing claw formed on the fixing piece will catch on the back side of the bottom of the heating chamber.
The kneader can be attached to the heating chamber.

Problems to be Solved by the Invention According to the above configuration, (a) When fixing the kneader to the bottom of the heating chamber, it is necessary to insert the fixing piece into the hole and rotate it by a predetermined angle; I have no choice but to do so. Therefore, there is a strong possibility that a large amount of food particles, liquid juice, etc. may flow out from this hole, causing an inconvenience.

(b) Since both the upper heater and the lower heater are located within the heating chamber, they become a nuisance when the kneader is taken in and out, and the effective space, particularly the height, within the heating chamber is reduced.

There were problems like.

An object of the present invention is to solve the above-mentioned problems and provide a high-frequency heating device with a stirring function that is easy to use and easy to clean.

Means for Solving the Problems The high-frequency heating device of the present invention includes a heating chamber that uses a high-frequency oscillator, an upper flat heater, and a hot air heater as heat sources, and a bread container in which everything from kneading bread ingredients to baking is performed in the heating chamber. and a fixing claw provided on the lower outer surface of the support stand fixed to the bottom of the bread container in order to hold the bread container on the bottom surface of the heating chamber, and a fixing claw fixed to the bottom surface of the heating chamber and engaged with the fixing claw. It is equipped with a hook piece.

Effects With the above configuration, (a) the bread container can be fixed in the heating chamber by engaging the fixing claw provided on the outer surface of the lower part of the support base fixed to the container with the hook fixed to the bottom surface of the heating chamber; There is no need to make holes for fixing the container on the bottom of the heating chamber.

(b) By using an upper plane heater and a hot air heater, the heater can be removed from the heating chamber so that the heater does not get in the way when attaching and removing bread containers, and the effective space in the heating chamber, especially the height, can be increased. That's what I do.

(C) When baking sweet bread, pizza, etc. from mixing to primary fermentation in a bread container, molding it into one piece and baking it with a hot air heater, you can use a two-stage oven unique to hot air ovens with the ingredients for one cup of bread container. A hot-air microwave oven with a built-in bread container is extremely easy to use, as it allows you to prepare just the right amount for cooking.

The functions and effects of the above configuration will be described.

Due to the following (a), (b), and (c), the high-frequency heating device of the present invention is easy to use and easy to clean.

(a) To fix the bread container 11 to the bottom surface of the heating chamber 1, engage the fixing claw 13 provided on the lower outer surface of the support base 12 attached to the bread container 11 with the hook piece 14 fixed to the bottom surface of the heating chamber 1. Therefore, it is not necessary to make a hole for fixing the bread container in the bottom surface of the heating chamber 1.

(b) In order to make it easier to attach and detach the bread container 1], an upper flat heater 6a and a hot air heater 6 are provided, and the heater is removed from the heating chamber 1, thereby increasing the effective space, especially the height, in the heating chamber 1. are doing.

(C) The inner container of the bread container 11 for bread is about 2 for 1 loaf.
Q: Approximately 3Q for 1.5 loaves. Moreover, the baked volume increases by 2 to 3 times that of the dough. Therefore, when sweet bread, pizza, etc. are subjected to everything from mixing to primary fermentation in the bread container 11, and then molded in sections and placed on the turntable 32 to be subjected to secondary fermentation and baking, 32 turntables are not enough, and two Often necessary. In this case, in this embodiment where hot air is sucked in from the side of the heating chamber 1 for baking, a turntable with feet (equal level) can be stacked on top of the turntable 32 to perform two-stage cooking, which significantly improves usability. In this way, the bread container 11 can be used extremely effectively for two-stage cooking, which is unique to hot-air ovens.

Furthermore, in order to effectively use the space in the height direction within the heating chamber 1, it is preferable that the position of the contact surface between the support stand 12 and the bottom surface of the heating chamber 1 be as low as possible. Therefore, if a hole is made in this contact surface, a large amount of food particles and liquid juice will easily flow down, which is not preferable.

On the other hand, there is a through hole 1a on the bottom surface of the heating chamber 1 through which the meshing clutch section passes, and the vicinity of this hole 1a is formed into an upward convex shape to prevent food particles and liquid juice from flowing down.

In addition, when the present invention detects that a cooking container is fixed in the heating chamber, a control circuit centered on a microcomputer controls the sequence from kneading to baking bread, as well as sweet bread, mochi, rice cooking, white bread, etc. It is applied to high-frequency heating equipment that automatically selects the sequence for sauce, pizza, etc. from a control panel.

Effects of the Invention According to the present invention, it is possible to provide a high-frequency heating device having multiple functions such as an automatic bread maker, an oven range, and a single-function microwave oven that are easy to use and easy to clean.
