Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heating chamber configuration of a high frequency heating device with heater heating.

Conventional technology In general, in high-frequency heating with a function of a high-frequency heating device with a heater heating function, such as a grill function, it is more efficient to heat the object by bringing the object closer to the heater and adding high-frequency energy to cook at the same time. . As shown in FIG. 2, a rack 2 is placed on a heating object mounting table 1, an object to be heated 3 is placed on the rack 2, and cooking is performed in close proximity to a heater 4. When meat, fish, etc. are grilled, oil and oily smoke are scattered and the upper wall 6 of the heating chamber 5 is stained with oil. Also, as shown in Fig. 3
No. 796), a partition plate 8 is added for the purpose of preventing heat from flowing into the high-frequency oscillator 7.

Problems to be Solved by the Invention However, in such a structural drawing, the object to be heated 3
More scattered oil, oil smoke, etc. adhere to the upper wall 6 of the heating chamber. Generally, in a high frequency heating device with a heater heating function,
The heating chamber upper wall 6 is provided with a self-cleaning function. Generally speaking, the functional life of self-cleaning is short-lived in places where there is heavy oil, oil smoke, etc. Since the heating chamber upper wall 6 and the heating chamber side wall 9 are fixed by welding at point A,
Once the self-cleaning function is lost, it will not return to its original state unless the entire heating chamber is replaced, and replacing the entire heating chamber will be a heavy burden on the user.

Furthermore, in the conventional example shown in FIG. 3, the partition plate 8 is
A self-cleaning plate is fixed to the upper wall 6 of the heating chamber with screws 1o. In other words, with the same structure, even if the self-cleaning function is lost, only the partition plate 8 can be replaced. Furthermore, in order to avoid the adverse effects of heat on the high frequency oscillator 7, it is also provided with the effect of a heat insulating plate. That is, the partition plate 8 is provided at a position spaced apart from the upper wall 6 of the heating chamber by X dimension. Therefore, the position of the heater 4 is also lowered, and as a result, the dimension 7 is lowered, and the volume of the heating chamber 5 is reduced, which is not effective.

Further, the heating chamber side wall 9 constituting the heating chamber 5. Heating chamber upper wall6.
Heating chamber lower wall 11. A high frequency current constantly flows through the partition plate 8. In other words, the larger the area constituting the heating chamber 5, the greater the loss of high frequency energy due to high frequency current. It also depends on the size of the load to be heated, and the energy loss tends to be large when the load is relatively light.

The present invention solves these conventional problems, and provides a high-frequency heating device with a heater function that solves the above-mentioned problems with a simple configuration and is more cost-effective and has an excellent heater function.

Means for Solving the Problems The partition plate of the present invention is configured such that only the periphery of the partition plate is in close contact with the upper wall of the heating chamber constituting the heating chamber, and is removably attached.

Function: The partition plate of the present invention is in close contact with the upper wall of the heating chamber constituting the heating chamber and its surroundings within about 20 ff1, and the inside thereof is hollow to eliminate loss of high frequency energy, and the partition plate can be attached and detached with screws. By doing so, partition plates that have lost their self-cleaning function can be replaced.

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. 1, a heating chamber upper wall 6 constituting the heating chamber 5
Attach the partition plate 8 with the self-cleaning function to the screw 1.
Fixed at 0. The heating chamber upper wall 6 and the partition plate 8 are brought into close contact with each other by five dimensions from the circumference of the partition plate 8.

In this way, only the circumferential dimension of the flat partition plate 8 is in contact, so there is no non-contact part, and the heating chamber 5
Even so, the shape is extremely simple, the area constituting the heating chamber can be kept to a minimum, and the loss of high frequency energy is reduced. Further, the volume of the heating chamber 5 can also be increased by 7 dimensions.

The partition plate 8 can be easily attached and removed by loosening the screws 10, and the space between the partition plate 8 and the heating chamber upper wall 6 also has the effect of serving as a heat insulating material during oven heating.

It should be noted that the dimension 5 is desirably within 2 o'clock in order to ensure tight contact with the upper wall of the heating chamber.

Effects of the Invention As described above, in the high-frequency heating device with a heater heating function of the present invention, the partition plate is made detachable, and the partition plate is installed so that only the upper wall of the heating chamber and the periphery of the partition plate are completely attached. By making the partition plate removable, even if the self-cleaning function of the partition plate is lost, the user can replace the partition plate at a low cost, and the surface area that makes up the heating chamber can be kept to a minimum. This not only makes it possible to minimize high-frequency energy loss, but also has the effect of insulating the space between the upper wall of the heating chamber and the partition plate, thereby saving energy when heating the heater. Furthermore, by configuring the partition plate flat, it is possible to provide the user with a high-frequency heating device with a heater function that is more convenient to use and more energy-saving without sacrificing the volume of the heating chamber.
