It is.

Hereinafter, the deodorizing catalyst structure of the electric oven of the present invention will be described in detail.

The deodorizing catalyst structure of the electric oven according to the present invention, the vibration energy of the ultrasonic vibrator 22 amplified through the horn 24 acts on the cavity 2 so that foreign matters generated during food heating are coated on the inner wall of the cavity 2. While preventing the micropores 21 of the coating material 20 from being blocked, the ultrasonic vibrator 22 is formed on the outer wall of the cavity 2 so that the deodorizing performance of the cavity 2 through the catalyst coating material 20 is always maintained. And a horn 24 for amplifying the vibration displacement applied from the ultrasonic vibrator 22, and the present invention will be described in detail. The same reference numerals will be applied to the same configurations as those of the present invention and the conventional art described above.

At this time, since the configuration of the electric oven to which the present invention is applied is the same as the configuration of the general electric oven described in the prior art, a description of the configuration of the electric oven according to this will be omitted, and in the detailed description of the present invention, Only the deodorizing catalyst structure of the oven will be described.

Deodorization catalyst structure of the electric oven according to the present invention, as shown in Figure 3, is installed in a case (not shown), the catalyst coating material 20 is coated to deodorize the odor generated during food heating through the catalytic action Cavity 2; An ultrasonic vibrator 22 installed at a predetermined position outside the cavity 2 and converting the supplied electrical signal into vibration energy having a predetermined amplitude; An ultrasonic oscillator 23 connected to the ultrasonic vibrator 22 and supplying an electrical signal to generate vibration energy in the ultrasonic vibrator 22; A horn 24 installed between the cavity 2 and the ultrasonic vibrator 22 to amplify the displacement of the vibration energy generated from the ultrasonic vibrator 22 to act on the cavity 2; It is.

In particular, in the ultrasonic vibrator 22, an ultrasonic wave having a frequency of vibration of 20,000 Hz or more, which is an audible limit, is oscillated. In this case, when the ultrasonic wave is oscillated by a solid medium having a very strong molecular structure, strong bonds between molecules and molecules are ultrasonic. When the solid medium is broken and broken, the ultrasonic wave is oscillated by a weak or free liquid medium, and the liquid boils through more active free movement between molecules. .

By using such ultrasonic waves, the food molecular structure in the cavity 2 is activated, and both the outer surface and the inside of the food are uniformly formed by the heat of the heaters 7 and 9 while the molecular structure of the food is activated as described above. It will be heated.

The food is put into the cavity 2 and the door 3 is closed to cook in a state in which the cavity 2 is sealed by the door 3, at which time the upper part installed on the upper part of the cavity 2 is provided. At the same time as heating the food in the radiation (copy) and convection (convection) method through the heater (9), ultrasonic waves are also oscillated from the ultrasonic vibrator 22 installed at a predetermined position outside the cavity (2). In the case of the ultrasonic wave oscillated from the ultrasonic vibrator 22, the intermolecular movement of the food by the ultrasonic wave is actively performed while being transferred to the food in the cavity 2, the intermolecular movement of the food is actively activated as described above It promotes heat transfer to the inside and heats the food evenly.

However, when the food is heated in the cavity 2 as described above, a foreign substance is generated, which part of the food splashes with the smoke, and the foreign matter generated as described above is deodorized in the cavity 2 through catalysis. Filled in the fine pores 21 of the catalyst coating material 20 coated on the inner wall of the cavity (2) for the purpose to block the fine pores 21, the fine pores 21 of the catalyst coating material 20 by the foreign matter in this way When clogged, foreign substances blocking the fine pores 21 of the catalyst coating material 20 are removed through the ultrasonic vibrator 22 and the horn 24 installed outside the cavity 2.

The removal process of the foreign matter blocking the micropores 21 through the ultrasonic vibrator 22 and the horn 24 will be described in more detail. First, the cavity 2 is connected to the ultrasonic vibrator 22. When an electrical signal is supplied from the ultrasonic oscillator 23 installed at a predetermined position to the ultrasonic vibrator 22, the ultrasonic vibrator 22 converts the supplied signal into vibration energy of a predetermined amplitude and the cavity ( 2) and the horn 24 provided between the ultrasonic vibrator 22 to amplify the displacement of the vibration energy generated from the ultrasonic vibrator 22 to act on the cavity 2, at this time, the cavity 2 The entire cavity 2 vibrates finely by vibrating energy applied to the vibrator, ie, the vibrating energy of the ultrasonic vibrator 22 amplified through the horn 24, and fine vibration of the cavity 2 as described above. Foreign body according to In other words, foreign substances blocking the fine pores 21 of the catalyst coating material 20 coated on the inner wall of the cavity 2 are separated from the fine pores 21 while deodorizing the catalyst coating material 20 through the catalytic process. The action is made (see FIG. 4).

Furthermore, when the vibration energy of the ultrasonic vibrator 22 amplified through the horn 24 is applied to the cavity 2 so that the entire cavity 2 vibrates finely, the catalyst coating material blocked by the foreign matter as described above. The foreign matter blocking the micropores 21 of the 20 is separated from the micropores 21 so that the deodorizing action of the catalyst coating material 20 is performed, and the cavity 2 is formed by foreign matters generated during food heating. It also serves to prevent the micropores 21 of the catalyst coating material 20 coated on the inner wall is blocked in advance.

Note that the deodorizing catalyst structure of the electric oven configured as described above can be applied not only to the electric oven described in the embodiment of the present invention but also to a microwave oven for cooking food using a high frequency as a heating source.
