[0052] Hereinafter, embodiments according to several aspects of the present invention will be described with reference to Figures 1 to 23. Note that the drawings illustrate specific examples of the several aspects, and the scope of the present invention is not limited to the embodiments.

[0053] Fig. 1 shows a cross-sectional view of an electromagnetic wave radiation device according to some embodiments of the present invention. The electromagnetic wave radiation device includes a magnetron 1, a member 2 corresponding to the first base described above, and a base 3 corresponding to the second base. The member 2 is composed of a bottom 2a and a peripheral portion 2b that forms an angle Φ with the bottom 2a. The base 3 is located on the opposite side of the bottom 2a from the tip of the magnetron 1. The base 3 and the peripheral portion 2b form an angle Θ.

[0054] Magnetron 1 protrudes from bottom 2a, and the tip of magnetron 1 is surrounded by peripheral portion 2b. As a result, microwaves generated by magnetron 1 are reflected by peripheral portion 2b and travel in the direction in which magnetron 1 protrudes from bottom 2a, and then travel in the direction of object A to be heated placed on top plate 4.

[0055] Although the member 2 in FIG. 1 has a configuration in which the flat bottom portion 2a and the surrounding portion 2b around the bottom portion 2a are shown, the configuration is not limited to this, and for example, the bottom may have a curved surface.

[0056] Figure 2 shows a cross-sectional view of an electromagnetic wave emitting apparatus equipped with a plurality of electromagnetic wave emitting devices. The configuration of each electromagnetic wave emitting device is the same as that of Figure 1 described above. As shown in Figure 2, a distance adjustment unit 5 is provided between two electromagnetic wave emitting devices to adjust the distance between the two electromagnetic wave emitting devices. In Figure 2, the distance adjustment unit 5 is made up of six plates, but the number of plates can be determined appropriately depending on the desired distance between the electromagnetic wave emitting devices.

[0057] Although the object to be heated A may be arranged relative to one electromagnetic wave emission device as shown in FIG. 1, it is also possible to use a plurality of electromagnetic wave emission devices to heat one object to be heated B as shown in FIG.

[0058] 3 shows a cross-sectional view of an electromagnetic wave emission apparatus having an electromagnetic wave emission device including an electromagnetic wave emission device with a magnetron 1 and a semiconductor-type microwave emission element 6. The semiconductor-type microwave emission element 6 is disposed at the bottom of a box-shaped member 7. By using different types of microwave emission elements in this way, it becomes possible to vary the degree of heating, for example.

[0059] FIG. 4 shows an electromagnetic wave emission device including a magnetron 1, a position control unit 8, an electromagnetic wave reflecting unit 10, and a waveguide 20. The electromagnetic wave reflecting unit 10 is provided around the protruding portion of the magnetron 1 and has the function of reflecting the radiated microwaves toward the object to be heated A. The position control unit 8 controls the positions of the magnetron 1 and the electromagnetic wave reflecting unit 10, and can, for example, vary the distance between the magnetron 1 and the electromagnetic wave reflecting unit 10 and the object to be heated A. At least a portion of the magnetron 1 and the electromagnetic wave reflecting unit 10 can be configured to move inside the waveguide 20 during at least a portion of the period during which the distance between the magnetron 1 and the electromagnetic wave reflecting unit 10 and the object to be heated A is changed.

[0060] The position control unit 8 adjusts the distance between the magnetron 1 and the electromagnetic wave reflecting unit 10 and the object to be heated A. By doing so, the object to be heated A can be heated to a desired state.

[0061] In addition, the heating state of the heated object A can be measured using a temperature measurement means such as a radiation thermometer 11, and the measurement results can be transmitted to the heating control unit 12. Based on the signal from the heating control unit 12, the position control unit 8 can adjust the distance between the magnetron 1 and the electromagnetic wave reflecting unit 10 and the heated object A in real time so that the heated object A reaches the desired temperature.

[0062] The shape of the waveguide 20 is not particularly limited, but by making it cylindrical with a space inside as shown in FIG. 5, it is possible to reduce the positional bias of the microwaves irradiated onto the object to be heated.

[0063] 6 shows an electromagnetic wave emission device equipped with an electromagnetic wave emission adjustment unit 40. The electromagnetic wave emission adjustment unit 40 has a first main surface to which the magnetron 1 is attached and a second main surface opposite the first main surface, with a space provided between the first and second main surfaces, and electromagnetic waves radiated from the magnetron 1 from the first main surface side into the space are emitted from a plurality of slits 40a on the second main surface side.

[0064] In the configuration of the electromagnetic wave output adjustment unit 40 shown in Fig. 6, the dimensions, size, or shape of each of the multiple slits 40a in the vertical and horizontal directions are appropriately set by, for example, a movable shielding material (for horizontal direction) 42 and a movable shielding material (for vertical direction) 43. The movable shielding material (for horizontal direction) 42 and the movable shielding material (for vertical direction) can be driven by a shaft (for horizontal direction) 44a and a shaft (for vertical direction) 44b, respectively. Furthermore, the shaft (for horizontal direction) 44a and the shaft (for vertical direction) 44b are controlled by a shaft controller 41.

[0065] As described above, the electromagnetic wave emission adjustment unit 40 according to some aspects of the present invention allows the dimensions, size or shape of each of the multiple slits 40a to be appropriately set, making it possible to achieve a desired heating state depending on, for example, the heating state or temperature at a position on the heated object, or the type, shape or material of the heated object.

[0066] Fig. 7 shows a state in which the magnetron 1 and the electromagnetic wave emission adjustment unit 40 are closer to the heated object A. When changing from the state in Fig. 6 to the state in Fig. 7, the electromagnetic wave emission adjustment unit 40 can move inside at least a part of the waveguide 30.

[0067] In this electromagnetic wave emission device, as in the electromagnetic wave emission device shown in FIG. 4, the object to be heated A can be heated to a desired state by adjusting the distance between the magnetron 1 and the electromagnetic wave output adjustment unit 40 and the object to be heated A using the position control unit 8.

[0068] In addition, the heating state of the heated object A can be measured using a temperature measurement means such as a radiation thermometer 11, and the measurement results can be transmitted to the heating control unit 12. Based on the signal from the heating control unit 12, the position control unit 8 can adjust the heated object A and the distance between the electromagnetic wave output adjustment unit 40 and the heated object A in real time so that the heated object A reaches the desired temperature.

[0069] 8 shows an example of the structure of the second main surface of the electromagnetic wave output adjustment unit 40. Slits are provided on the second main surface so that microwaves radiated from the magnetron 1 can be emitted into the electromagnetic wave output adjustment unit 40. Note that a suitable selection can be made depending on the desired microwave emission conditions, such as through-holes instead of the slits, or a combination of slits and through-holes.

[0070] 9 shows an electromagnetic wave emission device equipped with a semiconductor-type microwave emission element 6 and a position control unit 8 that controls the distance between the semiconductor-type microwave emission element 6 and the top plate 4 or the object to be heated A. The position control unit 8 has a built-in microwave transmission cable for transmitting microwaves to the semiconductor-type microwave emission element 6. The semiconductor-type microwave emission element 6 is placed at the bottom of a box-shaped member 7, and a recess or through-hole 7a is provided so that the position control unit 8 can fit in when the semiconductor-type microwave emission element 6 is at the farthest position from the object to be heated A.

[0071] In this electromagnetic wave emission device, similarly to the electromagnetic wave emission devices shown in Figures 4, 6 and 7, the distance between the semiconductor microwave emission element 6, which is the electromagnetic wave emission element, and the object to be heated A can be adjusted by the position control unit 8 to bring the object to be heated A into a desired heating state.

[0072] In addition, the heating state of the heated object A can be measured by a temperature measuring means such as a radiation thermometer 11, and the measurement results can be transmitted to the heating control unit 12.The position control unit 8 can then adjust the distance between the semiconductor microwave radiating element 6 and the heated object A in real time based on a signal from the heating control unit 12 so that the heated object A reaches the desired temperature.

[0073] Fig. 10 shows an electromagnetic wave emitting apparatus that includes four electromagnetic wave emitting devices that use magnetrons 1 as electromagnetic wave emitting elements, and further includes a control unit 60 that controls the four electromagnetic wave emitting devices. The control unit 60 that controls the four electromagnetic wave emitting devices is embedded in a base 70. Although not shown in Fig. 10, which is a view from above, a support that supports the base 70 is provided below the base 8.

[0074] FIG. 11 shows an electromagnetic wave emitting apparatus including two electromagnetic wave emitting devices, each using a magnetron 1 as a microwave emitting element, and two electromagnetic wave emitting elements, each including a semiconductor-type microwave emitting element 6, and further including a control unit 60 that controls the four electromagnetic wave emitting devices. The control unit 60 that controls the four electromagnetic wave emitting devices is fitted into a base 70. Note that while FIG. 11 shows the same type of electromagnetic wave emitting devices arranged horizontally, the same type of electromagnetic wave emitting devices may also be arranged vertically or diagonally. The arrangement of the electromagnetic wave emitting devices is determined appropriately depending on the type of object to be heated and the desired heating conditions.

[0075] At least one of the electromagnetic wave emission devices having the position control section 8 shown in FIGS. 4, 6 and 9 can be fitted into the base 70 together with the control section 60 for use.

[0076] FIG. 12 shows an electromagnetic shielding member 80 according to some embodiments of the present invention. In FIG. 12, the recessed portion of the electromagnetic shielding member 80 faces downward. The electromagnetic shielding member 80 is composed of a bottom portion 80a of the recessed portion and a peripheral portion 80b surrounding the bottom portion 80a. Of these, it is preferable that at least one of the bottom portion 80a and the peripheral portion 80b comprises a wire mesh or a punched metal. It is also preferable that both the bottom portion 80a and the peripheral portion 80b comprise a wire mesh or a punched metal.

[0077] Furthermore, by adjusting the electromagnetic wave shielding member 80 to the shape and size of the above-mentioned electromagnetic wave radiation device or electromagnetic wave radiation apparatus, it is possible to accommodate the heated object between the electromagnetic wave radiation device or electromagnetic wave radiation apparatus and the recessed portion of the electromagnetic wave shielding member 80, and it is also possible to suppress leakage of microwaves.

[0078] FIG. 13 illustrates an example of an electromagnetic wave-emitting device, a micro-emitting device 100, according to some embodiments of the present invention.

[0079] The microwave radiating equipment 100 includes a heating chamber 101, a waveguide holder 102, a heated object identifying section 105 for identifying the heated object A and the heated object B, a microwave radiating device set MS of multiple types of microwave radiating devices 100, 120, and 130, a heated object placing section 190 for placing the heated objects A and B, a device holder 200 for selecting a microwave radiating device from the microwave radiating device set MS, a moving section 210 for moving the device holder 200 to a desired position, a waveguide holder 260 for selecting multiple waveguides 150 and 160, a moving section 250 for moving the waveguide holder 260, a transport jig 140 for transporting the microwave radiating device selected by the device holder 200, and a heating device for heating the microwave radiating device while it is housed in the transport jig 140. The microwave radiating device is provided with a conveying unit 104a that pushes it toward the chamber 101, a conveying unit 104b that pushes it again toward the microwave radiating device set MS after use, conveying paths 103a and 103b on which the conveying units 104a and 104b move, a shutter 300 that is used when the heated object A and the heated object B are placed on the mounting unit 190 and moved into the heating chamber 101, a shutter 400 that is used when the waveguide holding unit 260 holds the waveguide and moves into the heating chamber 101, a shutter 350 that is used when the microwave radiating device is housed in the conveying jig 140 and pushed out by the conveying unit 104a into the heating chamber 101, and a position setting unit 180 that sets the position of the microwave radiating device relative to the heated object.

[0080] A typical operation of the microwave radiating device 100 will be described below, but the operation is not limited to the following description, and the operation procedure can be set as appropriate.

[0081] First, as shown in FIG. 14, the microwave radiating equipment 100 is transported by the moving unit 250 into the heating chamber 101 to be used, with the waveguide holding unit 260 selecting a waveguide corresponding to the microwave radiating device and holding the selected waveguide, and the waveguide holding unit 102 holds the waveguide.

[0082] At this time, each of the waveguide holders 102 is controlled to protrude in a direction perpendicular to the paper surface according to the size of the waveguide to be held, thereby making it possible to arrange waveguides of different sizes at desired positions.

[0083] Furthermore, the microwave radiating device 100 is configured such that when the waveguide holder 260 moves into the heating chamber 101, the shutter 400 opens.

[0084] Next, as shown in FIG. 15, the waveguide gripper 260 is moved out of the heating chamber by the moving part 250, and the shutter 400 is closed.

[0085] 16, the object to be heated A and the object to be heated B are placed on the placement part 190 and the object to be heated are moved to the heating chamber 101. At this time, the shutter 300 opens, and some of the multiple pedestals of the position setting part 180 rise to a height sufficient to receive the placement part 190.

[0086] Next, as shown in FIG. 17, the base of the position setting unit 180 that has received the mounting portion 190 is lowered, and the mounting portion 190 on which the heated object A and the heated object B are placed is placed on the waveguide already held by the waveguide holding portion 102.

[0087] Next, as shown in FIG. 18, a determination is made as to the type or appropriate heating state of the heated objects A and B identified by the heated object identification unit 105, and based on this determination, a microwave radiating device selected from the microwave radiating device set MS is grasped by the device grasping unit 200, moved by the moving unit 210, and placed on the transport jig 140.

[0088] 19, the selected microwave radiating device 120 housed in the transport jig 140 is transported by the transport unit 104a to the heating chamber 101. At this time, the position selection unit 180 receives the microwave radiating device in the heating chamber.

[0089] After the microwave radiating device 120 with a reflector is placed in the heating chamber 101, a new transport jig 140 is prepared, and the semiconductor microwave device 130 is accommodated in the transport jig 140 by the device holder 200. Note that the device holder 200 may be used when the transport jig 140 is prepared.

[0090] Next, as shown in FIG. 20, all of the microwave radiating devices 110, 120 and 130 for heating the objects A and B are placed under the corresponding waveguides 150 and 160, respectively.
