Embodiment approach

[0021] Next, use figure 1 The high-frequency heating device 100 of this embodiment will be described.

[0022] figure 1 It is a block diagram showing the basic configuration of the high-frequency heating device 100 of this embodiment.

[0023] Such as figure 1 As shown, the high-frequency heating device 100 includes a surface wave exciter 103 , a high-frequency power supply unit 110 , a high-frequency power generation unit 120 , an installation table 101 on which an object to be heated 102 is placed, and the like. The high-frequency heating device 100 heat-processes an object to be heated 102 placed on an installation table 101 .

[0024] At this time, the high-frequency heating device 100 is set so that the frequency of the high-frequency power generated by the high-frequency power generation unit 120 and the excitation frequency of the surface wave exciter 103 have a predetermined frequency relationship with each other. The intended frequency relationship is set so that ...

Abstract

The high-frequency heating device (100) has: a high-frequency power generating part (120), which generates high-frequency power; a surface wave exciter (103), which uses surface waves to propagate high-frequency power to the heated object (102) heating; a high-frequency power supply unit (110), which supplies high-frequency power to the surface wave excitation body (103); and a setting table (101), which sets the object to be heated (102). The high-frequency power generator (120) sets the frequency and surface area of ​​the high-frequency power supplied to the surface wave exciter (103) according to the desired surface concentration of the high-frequency power near the surface wave exciter (103). The object to be heated (102) is heated according to the size relationship between the excitation frequency of the wave excitation body (103). Thereby, there is provided a high-frequency heating device (100) capable of changing the heating state in the thickness direction of an object to be heated (102).

Description

technical field [0001] The present invention relates to a high-frequency heating device having a surface wave exciter using a periodic structure. Background technique [0002] Conventionally, there has been disclosed a technology related to a high-frequency heating device that applies high-frequency power (high-frequency power) to a surface wave exciter using a periodic structure to heat a food or other object to be heated ( For example, see Patent Document 1). [0003] The high-frequency heating device of Patent Document 1 has an impedance variable section that changes the impedance of the terminal portion of an interdigitated tape line (interdigitated tape line) (surface wave line) over time. The variable impedance portion changes the standing wave distribution over time to move a portion that radiates relatively strong energy. Thereby, the whole food is heated efficiently. [0004] That is, the above-mentioned high-frequency heating device changes the standing wave dis...
