Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a high-frequency heating device, and more particularly to an improvement in a high-frequency heating device having a turntable function that rotates cooked food during cooking to eliminate uneven heating.

Conventional structure and its problems Conventionally, various measures have been taken to eliminate uneven heating of cooked products in high-frequency heating devices, so-called microwave ovens.The main one is to rotate high-frequency waves using a motor. There are two methods: a stirrer system that uses a metal plate to reflect the light, and a turntable system that uses a motor to rotate a table on which food is placed.

Hereinafter, a conventional high frequency heating device as described above will be explained with reference to the drawings.

FIG. 1 shows a conventional stirrer-hane type high-frequency heating device. In Figure 1, 1 is a magnetron that generates high frequency waves, 2 is a heating chamber that cooks food using the high frequency radio waves generated by magnetron 1, and 3 is a waveguide that guides the high frequency radio waves generated by magnetron 1 to heating chamber 2. , 4 is a stirrer that reflects high-frequency radio waves to eliminate uneven heating of food, and 5 is a drive motor that rotates the stirrer 4.

The operation of the high-frequency heating device configured as described above will be described below.

The high-frequency radio waves generated by the magnetron 1 are guided to the heating chamber 2 by the waveguide 3 and cook the food placed on the bottom of the heating chamber 2. In this case, the shape of the heating chamber 2 and the shape of the waveguide 3 The distribution of radio waves within the heating chamber 2 is determined by the mounting position and the like. Depending on the position within the heating chamber 2, there are areas where the radio waves are strong and areas where the radio waves are weak, and when food placed in the heating chamber 2 is heated, uneven heating occurs. To eliminate this uneven heating, it is necessary to make the radio wave distribution within the heating chamber 2 uniform. For this purpose, a stirrer blade 4 rotated by a drive motor 5 is provided above the heating chamber 2, and high-frequency radio waves are applied to the stirrer blade 4. The radio wave distribution within the heating chamber 2 was made uniform by reflection and disturbance.

However, in the above configuration, the heating chamber 2
This had the disadvantage that the internal volume could not be used effectively. A stirrer blade 4 for reflecting and disturbing high-frequency radio waves must be installed at the top of the heating chamber 2, and the effective height l' at which food can actually be placed in the heating chamber 2 is the actual height of the heating chamber. Compared to the height l, it is lowered by the amount by which the stirrer blade 4 is attached. For this reason, tall foods cannot be cooked without entering the heating chamber 2, and if you want to ensure the effective height l' in the heating chamber 2 to cook tall foods, you will need a high-frequency heating device. The main body itself had to be made higher.

In addition to the stirrer type, there is a turntable type that eliminates uneven heating of food. below,
A conventional turntable-type high-frequency heating device will be explained with reference to the drawings.

FIG. 2 shows a conventional turntable type high frequency heating device. In FIG. 2, 2 is a heating chamber, 6 is a round saucer that rotates with food placed thereon, 7 is a rotary drive motor that rotates the round saucer 6, and 8 is a rotary drive motor that applies the rotational force from the rotary drive motor 7 to the round saucer 6. The rotating receiving shaft 9 for transmitting the information is a rotating ring that supports the rotating round receiving plate 6. In the above configuration, food is placed on the round saucer 6 that is slowly rotated by the rotary drive motor 7, and by rotating the food, high-frequency radio waves are uniformly applied to the food, thereby eliminating uneven heating of the food. .

However, even in the turntable type configuration as described above, there is a drawback that the volume of the heating chamber 2 cannot be used effectively. The only things that need to be installed in the heating chamber 2 are the rotary bearing shaft 8, the rotary ring 9, and the round saucer 6, so the height of the heating chamber 2 can be used effectively. It cannot protrude from the round saucer. This is because if the food protrudes, it hits the wall of the heating chamber 2 and cannot rotate. Therefore, the corners of the heating chamber 2 cannot be used, and it is inconvenient that two or three long foods such as fish cannot be cooked side by side.

OBJECTS OF THE INVENTION In view of the above-mentioned drawbacks, the present invention provides a compact and space-saving high-frequency heating device that enables the combined use of a turntable method and a stirrer fan method, and can effectively utilize the volume of a heating chamber.

Structure of the Invention In order to achieve this object, the high frequency heating device of the present invention includes a heating chamber provided in a main body, a heating device that heats the inside of the heating chamber, a round saucer on which food is placed and rotates, and a rotating round tray on which food is placed. a rotary drive motor that rotationally drives the saucer; a rotary receiver shaft that is attached to the shaft of the rotary drive motor and rotates the round saucer; a rotating ring that supports the rotating round saucer; and a rotary ring that can be freely attached to and detached from the rotary receiver shaft. It consists of a stirrer and a square saucer that can be used to fill the bottom of the heating chamber.

With this configuration, when cooking food that does not protrude from a normal round saucer, the rotary ring can be placed on the bottom of the heating chamber, and the round saucer can be attached to the rotating shaft from above, allowing the turntable method to be used. This allows for even heating, and for cooking long foods such as fish that protrude from the round saucer, remove the round saucer and rotating ring, and instead attach a stirrer to the rotating receiver and cook from above. A round saucer is placed upside down to cover the stirrer, and a square saucer that can be effectively used to fill the bottom of the heating chamber is placed on top of it, so that cooking can be performed without uneven heating using the stirrer method.

With the configuration described above, the turntable method and stirrer method can be used depending on the food, and the volume of the heating chamber can be used effectively.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIGS. 3 and 4 show the configuration of a high-frequency heating device in an embodiment of the present invention. The configuration shown in FIG. 3 is the configuration when the present invention is used as a turntable system, in which 2 is a heating chamber, 6 is a round saucer, 7 is a rotary drive motor for rotating the saucer,
Reference numeral 8 denotes a rotary receiver shaft that matches the concave portion of the saucer and rotates the saucer by the rotational force from the rotary drive motor, and 9 is a rotating ring that supports the circular saucer in order to stably rotate the saucer.

Next, FIG. 4 shows a configuration when the present invention is used as a stirrer-hane system. 2 is a heating chamber, 7 is a rotary drive motor, 8 is a rotary receiving shaft, 10 is a stirrer that is attached to the rotary receiving shaft and reflects and disturbs radio waves while rotating, and 11 is a corner that can be used to fill the bottom of the heating chamber 3. The mold saucer 12 is the round saucer 6 used in the turntable system shown in FIG. 3, but here it is a square saucer stand that is placed over the stirrer wings 10 and the square saucer 11 so that they do not come into contact with each other.

The operation of the high frequency heating device constructed as shown in FIGS. 3 and 4 will be explained above. First, FIG. 3 shows a configuration for cooking food using a normal turntable method, but this is used when the food is large enough not to protrude from the round saucer 6. This method uses rotational force from a rotary drive motor 7 to rotate a round saucer 6 mounted on a rotary bearing shaft 8 and supported by a rotary ring 9, thereby rotating the food itself, thereby eliminating uneven heating. Can be done. In this method, there is no need to install a stirrer inside the heating chamber 2, so the height of the heating chamber 2 can be used effectively, and even tall foods can be cooked.

Next, the operation when used as the stirrer mechanism shown in FIG. 4 will be explained. This is used when the food protrudes from the round saucer 6, for example when cooking two or three long fish side by side. A round saucer 6 and a rotating ring 9 are removed, and a stirrer blade 10 is attached to a rotating heavy shaft 8 so that it can be rotated by a rotational drive motor 7. Place the round saucer 6 that was used in the turntable method upside down on top of the stirrer 10, and replace the square saucer stand 1.
2, stirrer blade 10 and square saucer 1
Avoid hitting 1. With this configuration, in which the square saucer 11 is placed on the square saucer stand 12, even food such as fish that protrudes horizontally from the round saucer can be cooked without uneven heating by using the stirrer. .

According to this embodiment as described above, it is possible to use both the turntable method and the stirrup method,
The turntable method can be used to cook tall foods that do not protrude from the round saucer.
If the food protrudes from the round saucer and cannot be rotated using the turntable method, the stirrer method can be used. By making it possible to use both the turntable method and the stirrer method in this way, the limited volume of the heating chamber 2 can be used effectively, and cooking can be performed without uneven heating. In addition, the transition from the turntable system to the stirrer blade system involves removing the round saucer 6 and rotating ring 9, attaching the stirrer blade 10 to the rotating bearing shaft 8, and placing the round saucer 6 on the square saucer stand 12 with the round saucer 6 reversed. It is as simple as placing a rectangular saucer 11 on the plate. Furthermore, among the parts of the turntable type and the stirrer type, the round saucer 6 (square saucer stand 12), rotational drive motor 7, and rotary receiving shaft 8 are commonly used, which is advantageous in terms of economy.

Effects of the Invention As described above, the present invention allows heating cooking using the turntable method and stirrer heating method in combination, making it possible to effectively utilize the limited volume of the heating chamber, and achieving cooking performance without uneven heating. We can provide high-frequency heating equipment with good quality. Furthermore, it is easy to transition from the turntable system to the stirrer system, and since many parts of both systems are shared, it is highly functional and economical. As described above, the present invention has great practical effects.
