Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cooking device, and particularly to a cooking device that cooks food using high-frequency heat radiation from a heater disposed in a cooking chamber.

[Prior Art] Microwave ovens that cook food using the principle of heating a dielectric material such as water or oil by irradiating it with high-frequency power are widely used. According to this principle, there are various advantages such as shortening of heating time and uniform heating, which improves the quality of thawing and cooking of frozen foods, and is becoming an indispensable cooking tool for modern diets.

Heating in a microwave oven involves doubling and rectifying the several MHz voltage generated on the secondary side of a high-voltage transformer using a diode and a high-voltage capacitor, and applying this to the anode of a magnetron, causing it to oscillate. To do this.

FIG. 2 shows an external perspective view of a general microwave oven. A cooking chamber (3) in which a rotatable food tray (2) is arranged is formed inside the box-shaped case (1), and the user can access the cooking chamber (3) by opening and closing the door (4). ) to store and take out the food to be cooked. Case (1) Front galley (3
) An operating section (6) including a timer (6b) and a start switch (6a) for setting the heating time and heating power is provided on the side.

The heating section, which mainly consists of a high-voltage transformer, a high-voltage condenser, and a magnetron, is used in the case (1) to generate the aforementioned high-frequency heat rays and to irradiate the foods in the cooking chamber (3).
and the cooking chamber (3).

Conventional microwave ovens generally have the above-mentioned configuration, and when used, the user opens the door (4), sets food on the food tray (2) in the cooking chamber (3), and then closes the door. (4
), set the timer (6b) to a predetermined scale position, and turn on the start switch (6a), the high-frequency heating wire is guided from the heating section into the cooking chamber (3) via a waveguide (not shown). , food will be prepared. Since the circular food tray (2) rotates at a predetermined speed at the same time as cooking starts,
The food on the placing plate (2) can be heated evenly and evenly.

[Problems to be Solved by the Invention] However, the configuration of the conventional microwave oven described above has a problem in that the space efficiency is low and the entire device is large compared to the space actually used.

That is, as is clear from FIG. 3 which shows a schematic plan view of the device according to FIG. 2, in the conventional device, although the food tray (2) is circular, the cooking chamber (3) is square. It is formed as a box. 1. Since the food set on the food placement plate (2) is subjected to rotational action at the same time as cooking starts as described above, its size must fall within the diameter of the food placement plate (2). . Therefore, although the cooking chamber (3) should originally be large enough to accommodate the circular food tray (2), the shape of the circular food tray (2) is Since the shape was different from the square shape, the circular food tray (2) and the cooking chamber (3) were created as shown in Figure 3.
An unnecessary space is created between the wall surface (3a) and the wall surface (3a).

On the other hand, a heating section (7) consisting of a high-voltage transformer, a high-voltage condenser, a magnetron, etc. is located on the side of the cooking chamber (3) in a space formed between the wall (3a) of the cooking chamber (3) and the case (1). are arranged separately and independently within the

Therefore, the space created between the wall (3a) in the cooking chamber (3) and the food tray (2) is an unused and wasted space, which is a major factor in increasing the size of the entire device.

Purpose of the Invention The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to provide a heating system that can effectively utilize the space created between each component and miniaturize the device. It is about providing the equipment.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a method in which the shape of the cooking chamber of a microwave oven is curved along the outer diameter of a circular food tray disposed inside the cooking chamber. The microwave oven is characterized in that the heating section is disposed within the space created between the curved cooking chamber wall and the case of the microwave oven.

[Function] With the above configuration, according to the present invention, the heating section of a microwave oven, which conventionally required a dedicated installation space separate from the cooking chamber, can be installed in the space created by making the cooking chamber curved. This makes it possible to save a large amount of space and reduce the size of the device by eliminating wasted space.

[Example] Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

FIG. 1 shows a schematic plan view of a heating cooker according to the present invention.

In the figures, the same components as those of the conventional device are designated by the same reference numerals, and their explanations will be omitted.

A characteristic feature of the present invention is that the cooking chamber (3), which was conventionally usually formed in the shape of a square box, is made into a curved shape along the outer diameter of the circular food tray (2). The space created between the case (1) and the cooking chamber (3a) is effectively utilized, and the heating section for irradiating high-frequency heat rays is housed in the cooking chamber (3). .

That is, as is clear from the figure, in the present invention, a cooking chamber (3b ) is formed into a curved surface along the shape of the food placing plate (2) from the side wall surface to the back wall surface.

Therefore, there is a large gap between the circular placing plate (2) and the wall (3a) of the cooking chamber (3), especially between the side wall and the back wall, which occurred in the conventional device shown in FIG. It is understood that wasted space has been eliminated.

In the present invention, a heating section (7) consisting of a high-voltage transformer, a high-voltage condenser, a magnetron, etc. for irradiating high-frequency heat rays into the cooking chamber (3a) is connected to the case (1) forming the outer shell of the microwave oven and this curved surface. It can now be stored between the cooking chamber wall and the heating section storage space, which conventionally had to be formed on the side of the cooking chamber (3) for the heating section (7), is completely unnecessary. It is clear that a significant reduction in size has been achieved.

In such a configuration, although the volume of the cooking chamber (3) is inevitably reduced compared to conventional devices, in this type of microwave oven, the food tray (2) does not start cooking. At the same time, since the rotary action is performed in a predetermined direction at a constant speed, the food set on the circular food tray (2)-L- is usually not subject to food that protrudes beyond its diameter.

Therefore, the space removed by making the cooking chamber wall curved as shown in the figure is an unnecessary space that conventionally caused the device to become larger, and it does not cause any inconvenience for food insertion and cooking operations. It's not what it brings.

In this way, according to the present invention, the common sense that the cooking chamber has a rectangular box shape, which was conventionally considered as a matter of course, has been broken, and the wall surface of the cooking chamber (3), especially from the side wall surface to the back wall surface, has been expanded. By making the part curved along the outer diameter of the circular mounting plate (2), a space that was previously not used at all was used for storing the heating unit, so that there was no deterioration in performance. It is possible to realize miniaturization of the device without any problems.

[Effects of the Invention] As explained above, according to the present invention, the cooking chamber of the heating cooker is configured with a curved wall along the outer diameter of the circular food placing plate, and the curved wall and the outer shell of the microwave oven are formed. By arranging the heating part in the space formed by the case, the heating part can be stored between this curved wall and the case as a storage space for the heating part, which conventionally had to be formed separately. This has the effect that space can be used effectively and the device can be downsized without any deterioration in performance.
