装置になる。 High-frequency heating devices have the disadvantage that food cannot be browned because the food itself absorbs high-frequency power and generates heat on its own. Therefore, a high-frequency heating device with an electric heating device was considered. Initially, a sheathed heater, which had an electric heating coil and an insulating filler built into a metal pipe, was used as an electric heating device. This sheathed heater has an electric heating coil covered by a metal pipe, so
The high frequency has no adverse effect on the electric heating coil and is suitable for safety, but on the other hand, it is unsatisfactory in its ability to scorch food because it is slow to reach a high enough temperature to enable infrared radiation. In order to improve this drawback, in recent years electric heating coils have been built into heat-resistant insulators such as quartz tubes. A so-called quartz tube heater is used. This is the high-frequency heating device with electric heating device shown in FIG. This will be explained below with reference to the drawings. High frequency waves generated from the magnetron 1 pass through a waveguide 2 and are diffused into a heating chamber 3. The diffused high frequency waves are absorbed by the object to be heated 4 and cooked by the heat generated by the object to be heated 4 itself. Thereafter, the food is browned using a quartz tube heater 5 and cooking is completed. In the quartz tube heater 5, the infrared rays generated from the electric heating coil pass through the quartz tube and are radiated directly to the object to be heated 4, so it is certain that the scorching speed is faster and the efficiency is improved. However, as shown in Figure 2, since the contact area between the quartz tube 6 and the electric heating coil 7 is large, the heat from the electric heating coil 7 is conducted to the quartz tube 6, so if this point is improved, the start-up will be faster and more efficient. It becomes a good electric heating device.

いた。 Furthermore, there is a risk that the electric heater 7 may fall due to vibrations during transportation, vibrations caused by opening and closing the door before or after cooking, etc., and the pitches of the electric heater 7 may be pinched and disconnected.

つたことにより強度が増し少なくなつた。 As shown in FIG. 1, high frequency waves generated from a magnetron 1 pass through a waveguide 2 and are diffused into a heating chamber 3. The diffused high frequency waves are absorbed by the object to be heated 4 and cooked by the heat generated by the object to be heated 4 itself. Thereafter, the food is browned using a quartz tube heater 5 and cooking is completed. Third
FIG. 4 shows the shape of an electric heater 8 constituting an embodiment of the present invention. Each turn of the electric heater 8 has a nearly elliptical shape as shown in Fig. 4, and the angle at which the ellipse is formed is changed for each turn so that adjacent ellipses do not overlap each other. be. Therefore, when viewed from one direction, it appears that the electric heater 8 is housed in the quartz tube 6 in a wavy manner as shown in Figure 3, but this is because the angle of the formed ellipse has been changed. Almost all of the elliptical shape formed by one turn of the electric heater 8 is in contact with the inner wall of the quartz tube 6 at both ends. The high-frequency heating device with an electric heating device, which incorporates the quartz tube heater 5 in which the electric heater 8 is inserted into the quartz tube 6, has a faster scorching speed and is more efficient than the conventional electric heater. This is because the contact area between the quartz tube 6 and the electric heater 8 is small due to the special winding method, so less heat is conducted to the quartz tube 6 and that amount is radiated directly to the object to be heated 4. . Furthermore, by twisting the electric heater, the strength of the heat loss due to the heater falling and falling due to vibrations caused by opening and closing the door before and after cooking is reduced.
