Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a high-frequency heating device with an electric heating device equipped with a coiled heating wire.

BACKGROUND ART Conventionally, as shown in FIG. 4, a general high-frequency heating device with an electric heating device has a heating chamber 12 in which food is stored and cooked in a main body 11, and a high-frequency wave is radiated into the heating chamber 12. and a heating device 14 disposed on the upper surface side to raise the atmospheric temperature in the heating chamber 12. It is arranged and configured. Conventionally, the heating device 14a consisting of a coiled electric heater 116a and a heat-resistant tube 15a as shown by the pseudophase line in FIG. 4 is not used as a heating means on the bottom side of the heating chamber 12.

Problems to be Solved by the Invention The reason why this heating device 14a is not used is that it cannot be attached or detached, so the heating adjustment is 1! I! There is a problem that it is difficult to remove dirt such as food scraps, broth, oil, etc. that later adheres to the bottom plate 17 of the heating chamber 12, and because the heat-resistant tube 15a is made of quartz glass tube, it is very susceptible to impact, and it is difficult to remove food particles. This is because there was a problem that there was a risk of it breaking when taking it in and out.

The present invention solves these conventional problems, and provides a more excellent high-frequency heating device with electric heating device in which a coiled heating wire can be disposed on the bottom side of the heating chamber with a simple configuration. It is.

Means for Solving the Problems In the high-frequency heating device with electric heating device of the present invention, the heating chamber is vertically partitioned by a partition plate made of a heat-resistant material, and a heating 8 made of a coiled heating wire is provided below the partition plate. place the
The purpose is to store food above the partition plate and heat it for cooking.

Function The high-frequency heating device with an electric heating device of the present invention divides a heating chamber vertically with a partition plate made of a heat-resistant material, and a heating device made of a coiled heating wire is disposed below the partition plate. Food is stored in the upper part, and food scraps, oil, etc. generated during heating and cooking adhere to the partition plate, making it easier to clean the heating chamber and making it more convenient to use. Furthermore, since the heating device is located below the partition plate, there is no fear that the heat-resistant tube will break while loading and unloading food. Furthermore, when the door is opened to check the food coming out during heating for 5g1U, the temperature inside the heating chamber will drop rapidly, but the high temperature partition plate will help keep the temperature of the heating chamber warm. The temperature will be less likely to drop, and the cooking time can be shortened.

EXAMPLE Hereinafter, a high-frequency heating device with an electric heating device according to an example of the present invention will be explained with reference to FIGS. 1 to 3.

In FIG. 1, a main body 1 is provided with a heating chamber 2 for storing and heating food, and a high-frequency generator 3 for emitting high-frequency waves into the heating chamber 2. Inside the heating chamber 2, there is a pair of upper and lower heating devices 4.5 for increasing the atmospheric temperature inside the heating chamber 2,
A partition plate 6 made of a heat-resistant material is provided to partition the inside of the heating chamber 2 in the vertical direction. The lower heating device 5 is disposed below the partition plate 6, and the upper heating device M4 is disposed above the partition plate 6 and above the heating chamber 2. Both heating devices 4 and 5 are
As shown in the figure, it consists of a coiled heating wire 7 and a heat-resistant tube 8 with good heat transmittance to protect the coiled heating fQ7, and the coiled heating wire 7 is arranged inside the heat-resistant tube 8. do. The heat-resistant tube 8 is generally a glass tube made of quartz.

As shown in FIG. 3, the partition plate 6 is fixed in the heating chamber 2 by applying putty 9 having high heat resistance on its outer periphery. The partition plate 6 can be used at the same time during high-frequency heating by using a phase gradient having high heat resistance, high heat permeability, low dielectric constant, and high frequency characteristics.

In this way, food scraps generated by heating,
Broth, oil, etc. adhere to the partition plate 6. With this partition plate 6, adhering food scraps, broth, oil, etc. can be easily removed, and the high-frequency heating device with electric heating device can be made easy to clean and easy to use. Although the heat-resistant tube 8 is provided in this embodiment, the heat-resistant tube 8 may be omitted depending on the partition plate 6. Note that in order to quickly raise the atmospheric temperature within the heating chamber 2, it is more desirable that the partition plate 6 be as thin as possible.

Effects of the Invention As described above, the high-frequency heating device with an electric heating device of the present invention is such that the heating chamber is vertically partitioned by a partition plate made of a heat-resistant material, and the heating device is disposed below the partition plate. This makes it very easy to clean food waste, broth, oil, etc. that are generated after cooking, making it very convenient to use.

In addition, when the door is opened to check the condition of the food being cooked, the temperature inside the heating chamber drops rapidly, but in this invention, the high temperature partition plate acts as a plow to keep the ambient temperature of the heating chamber warm. This also leads to time savings.

Especially when cooking continuously, the time can be greatly reduced.

Furthermore, even if a heating device to which 100V is applied is placed under the partition plate, it is no longer possible to touch this heating device with your hands. Therefore, electric shock 4 will not occur, leading to increased safety.
