Embodiment approach 1

[0026]

[0027] figure 1 , figure 2 It is a vertical cross-sectional view and a horizontal cross-sectional view schematically showing the structure of the high-frequency heating device 1 a according to Embodiment 1 of the present invention, respectively.

[0028] Such as figure 1 , figure 2 As shown, the high-frequency heating device 1 a has a heating chamber 2 , a generating unit 8 , a surface wave exciter 9 , a coupling unit 12 , and a control unit 14 . The surface wave exciter 9 includes a coupling portion 12 provided in the middle, and a surface wave exciter 9 a and a surface wave exciter 9 b provided to sandwich the coupling portion 12 .

[0029] The high-frequency heating device 1a is configured to heat the object to be heated 6 (in this embodiment, the objects to be heated 6a and 6b ) placed on the mounting table 4 using microwaves propagating on the surface of the surface wave exciter 9 in the surface wave mode. ) for heating.

[0030] Each component will be d...

Embodiment approach 2

[0056] Regarding the high-frequency heating device 1b according to Embodiment 2 of the present invention, the differences from Embodiment 1 will be mainly described. Figure 4 It is a cross-sectional view schematically showing the structure of the high-frequency heating device 1b. Figure 4 Schematically shows the situation in which microwaves in the surface wave mode propagate on the surface wave excitation body 9, and the heating target object 6 is placed on the mounting table 4 (in the Figure 4 not shown in the figure).

[0057] Such as Figure 4 As shown, the high-frequency heating device 1 b has coupling parts 22 , 24 and a distributor 26 in addition to the configuration of the first embodiment.

[0058] Coupling sections 22 and 24 are respectively provided at both ends of surface wave exciter 9 in microwave propagation direction D so as to supply microwaves generated by generating section 8 to surface wave exciter 9 . In this embodiment, the coupling parts 22 and 24 ...

Embodiment approach 3

[0065] Only the difference from Embodiment 2 will be described about the high-frequency heating device 1c according to Embodiment 3 of the present invention. Figure 5 It is a cross-sectional view schematically showing the structure of the high-frequency heating device 1c. Figure 5 Schematically shows the situation in which microwaves in the surface wave mode propagate on the surface wave excitation body 9, and the heating target object 6 is placed on the mounting table 4 (in the Figure 5 not shown in the figure).

[0066] Such as Figure 5 As shown, the high-frequency heating device 1 c further includes a generating unit 32 and a generating unit 34 . The high-frequency heating device 1 c includes a control unit 36 ​​configured to control the production units 8 , 32 , and 34 instead of the control unit 14 .

[0067] The high-frequency heating device 1c does not have the distributor 26 but has the coupling parts 22 and 24 respectively connected to the generating part 32 an...

Abstract

A high-frequency heating device (1a) has a first generating unit (8), a surface wave exciter (9), and a first coupling unit (12). The first generation unit (8) generates microwaves. A surface wave exciter (9) has a plurality of metal plates (11) periodically arranged at predetermined intervals in a microwave propagation direction, and heats a heating object (6) by propagating microwaves in a surface wave mode. The first coupling part (12) is arranged in the middle part of the surface wave excitation body (9) in the propagation direction (D) of the microwave, so that the microwave generated by the first generating part (8) passes through the first coupling part (12) It is supplied to the surface wave exciter (9). According to this aspect, the object to be heated can be heated more uniformly.

Description

technical field [0001] The invention relates to high-frequency heating devices such as microwave ovens. Background technique [0002] Conventionally, a high-frequency heating device has been developed that supplies microwaves to a surface wave transmission line to heat an object to be heated such as food. [0003] For example, Patent Document 1 discloses a high-frequency heating device that thaws frozen sushi placed on a surface wave transmission line by directly supplying microwaves to the surface wave transmission line. [0004] prior art literature [0005] patent documents [0006] Patent Document 1: Japanese Patent Application Laid-Open No. 8-166133 Contents of the invention [0007] In the field of high-frequency heating devices, how to heat an object to be heated more uniformly has been a long-standing problem. An object of the present invention is to provide a high-frequency heating device that contributes to solving the above-mentioned problems. [0008] A hi...
