Description

The present disclosure relates to an aging chamber for aging food by irradiating it with electromagnetic waves and a cooking device equipped with this aging chamber.

As an aging device for aging food by irradiating it with electromagnetic waves, an aging chamber equipped with a aging chamber for storing food and a microwave oscillating unit for irradiating the aging chamber with microwaves has been proposed. (See, for example, Patent Document 1). Since food spoilage progresses as the aging period becomes longer, the aging chamber of Patent Document 1 has an aging chamber arranged in a cooling chamber cooled by a cooler, and the cold air in the cooling chamber is blown into the aging chamber by a blower fan. It is sent to cool the surface of the food.

International Publication No. 2019/093365

In the aging chamber described in Patent Document 1, the aging chamber is arranged in the cooling chamber as described above, and the cold air in the cooling chamber is sent into the aging chamber by a blower fan. Since the air is forcibly blown into the aging room by the air blower fan, the surface of the food becomes easy to dry. When the surface of the food dries, the weight of the aged product obtained from the food decreases, and the yield decreases. Further, since the aging chamber of Patent Document 1 has a double structure consisting of two housings, a cooling chamber and an aging chamber, the parts cost and the assembly cost increase.

The present disclosure has been made in view of the above, and provides an aging chamber having a simplified structure and capable of improving the yield of an aged product, and a cooking device equipped with the aging chamber.

The aging chamber according to the present disclosure includes an aging chamber formed of a metal wall, an electromagnetic wave irradiator that irradiates the aging chamber with electromagnetic waves, and a cooling body that is thermally conductively connected to the wall of the aging chamber. It is provided with a cooling means having.

According to the present disclosure, since a cooling means connected to the wall of the aging chamber so as to be heat conductive is provided, the wall of the aging chamber is cooled by the cooling means, and heat is transferred from the wall of the aging chamber to the air in the aging chamber. The aging room can be cooled. Therefore, drying in the aging chamber is suppressed, and the yield when obtaining the aged product can be improved. Further, since the aging chamber and the cooling chamber are not provided separately as in Patent Document 1, the structure of the aging chamber is simplified.

In addition, the present disclosure includes all combinations of configurations that can be combined among the configurations shown in the following embodiments. Further, in the following description, terms indicating directions (for example, "top", "bottom", "right", "left", "front", "rear", etc.) are appropriately used for ease of understanding. These are for illustration purposes only and are not intended to limit this disclosure. Further, in each figure, those having the same reference numerals are the same or equivalent thereof, which are common to the whole text of the specification. In each drawing, the relative dimensional relationship or shape of each constituent member may differ from the actual one.

Embodiment 1.
FIG. 1 is a front perspective view of the aging chamber 100 according to the first embodiment. The aging chamber 100 is a device for accommodating a food material inside and heating the food material by irradiating the housed food material with an electromagnetic wave to ripen the food material to obtain an aged product. Further, the aging chamber 100 of the present embodiment cools the surface of the food material and suppresses the spoilage of the surface of the food material during the aging period.

The aging chamber 100 has a housing 10 made of synthetic resin or steel plate, and a door 3 made of synthetic resin or steel plate. The door 3 is provided with a display unit 1 and an operation unit 2. The display unit 1 has a device for visually notifying information such as a liquid crystal display or an LED, and displays information such as the aging time or the set temperature in the aging chamber 100, as well as information for warning and alerting the user. The operation unit 2 is composed of, for example, a push button, a dial switch, a capacitive touch switch, or the like. The operation unit 2 is for inputting the aging time, the set temperature, and the like.

The width of the rear portion of the housing 10 of the aging chamber 100 becomes narrower toward the rear. An intake port 4 is provided on the right side wall of the housing 10 which is inclined so as to have a narrow width in the housing 10. The intake port 4 is an air suction port for heat dissipation supplied to the first cooling means 30 and the second cooling means 35, which will be described later.

FIG. 2 is a rear perspective view of the aging chamber 100 according to the first embodiment. In the rear part on the left side of the housing 10, the side wall of the housing 10 has a curved outer surface. An exhaust port 5 is provided on the curved surface portion of the side wall. The exhaust port 5 is an outlet for heat radiation supplied to the first cooling means 30 and the second cooling means 35, which will be described later.

An intake port 4 is provided on the right side wall of the rear portion of the housing 10, and an exhaust port 5 is provided on the left side wall of the rear portion of the housing 10. As described above, since the intake port 4 and the exhaust port 5 are provided on the left and right side walls of the housing 10, when the aging chamber 100 is installed, a large gap for ventilation is provided at the rear portion of the aging chamber 100. There is no need. That is, since the rear cover 10a of the housing 10 of the aging cabinet 100 can be placed close to the wall of the room or cabinet, for example, the installation space of the aging cabinet 100 can be saved. Further, if the intake port 4 and the exhaust port 5 are provided on the rear cover 10a of the housing 10, the pressure loss may increase because the rear cover 10a is covered with the wall of the room or the cabinet. However, since the intake port 4 and the exhaust port 5 of the present embodiment are provided on a part of the side wall of the housing 10, it is difficult to be covered by the wall of the room or the cabinet, and the increase in pressure loss is suppressed. Further, since the intake port 4 and the exhaust port 5 are provided on an inclined surface or a curved surface of the side wall of the housing 10, the opening area can be increased while suppressing an increase in the depth dimension of the housing 10. Can be wide. By widening the opening areas of the intake port 4 and the exhaust port 5, the wind speed of the air passing through them becomes slow, and the pressure loss of the air when passing through the intake port 4 and the exhaust port 5 can be suppressed. By suppressing the pressure loss of the air in this way, it is possible to increase the cooling efficiency of the object to be cooled by the air sucked from the intake port 4.

Further, in the present embodiment, since the intake port 4 is provided on one of the facing side walls of the housing 10 and the exhaust port 5 is provided on the other side, the intake port 4 and the exhaust port 5 are not close to each other. Therefore, it is difficult for the air discharged from the exhaust port 5 to be directly sucked into the intake port 4, and the air close to room temperature can be sucked from the intake port 4. In this way, since the short cycle of air between the exhaust port 5 and the intake port 4 is suppressed, the cooling efficiency of the object to be cooled by the air sucked from the intake port 4 can be improved. The intake port 4 may be provided on the left side of the housing 10 and the exhaust port 5 may be provided on the right side of the housing 10, and the same technical effect can be obtained.

A filter 6 is provided at the intake port 4. The filter 6 is removable with respect to the intake port 4. The aging chamber 100 may be used in the kitchen, and dust, oily smoke, or the like may be floating in the kitchen. By providing the filter 6 in the intake port 4, it is possible to suppress the intrusion of such foreign matter such as dust or oil smoke into the intake port 4. Further, since the filter 6 is detachable from the intake port 4, the filter 6 can be easily cleaned and replaced, which is convenient for the user. By cleaning and replacing the filter 6 in a timely manner, the foreign matter collecting effect of the filter 6 can be maintained.

FIG. 3 is a rear perspective view of the aging chamber 100 according to the first embodiment, and shows a state in which the rear cover 10a and the filter 6 shown in FIG. 2 are removed. In the rear part of the housing 10, an electromagnetic wave generator 22, a decompression pump 41, and a control circuit 50 are provided in the upper part, and an electromagnetic wave generator 27 is provided in the lower part. A heat radiating blower 40 is provided inside the intake port 4, and a heat radiating fin 31 and a heat radiating fin 36 are provided on the blowing side of the heat radiating blower 40.

The heat radiation fin 31 is a part of the first cooling means 30, and the heat radiation fin 36 is a part of the second cooling means 35. The heat radiating fins 31 and the heat radiating fins 36 dissipate heat generated by cooling in the aging chamber 100.

The heat dissipation blower 40 sends air to the heat dissipation fins 31 and the heat dissipation fins 36. In the present embodiment, a plurality of heat radiating blowers 40 are arranged side by side one above the other. A first partition plate 42 for vertically partitioning the space is provided between the heat radiation fins 31 and the heat radiation fins 36. The heat radiation fins 31 are arranged on the first partition plate 42, the heat radiation fins 36 are arranged under the first partition plate 42, and the air is blown from different heat radiation blowers 40 above and below the first partition plate 42. Will be done. As described above, since the air duct for cooling the heat radiation fin 31 and the air duct for cooling the heat radiation fin 36 are separated from each other and the heat radiation blower 40 is provided for each, the heat radiation fin 31 and the heat radiation fin 36 are provided. The cooling capacity can be controlled individually.

The decompression pump 41 is a pump that decompresses the inside of the aging chamber 11 by sucking the air in the aging chamber 11 (see FIG. 4).

The control circuit 50 is a circuit that controls the operation of the aging chamber 100. The control circuit 50 is composed of dedicated hardware or a CPU (Central Processing Unit) that executes a program stored in a memory.

A second partition plate 43 that divides the space up and down is provided on the upper side of the heat radiation fin 31 at the rear of the housing 10. Further, on the lower side of the heat radiation fin 36, a third partition plate 44 for partitioning the space up and down is provided. The decompression pump 41, the control circuit 50, and the electromagnetic wave generator 22 are arranged on the second partition plate 43, and the electromagnetic wave generator 27 is arranged under the third partition plate 44. The upper side of the second partition plate 43 and the lower side of the third partition plate 44 are configured so that the air from the heat radiating blower 40 flows in, and each member is cooled by the air from the heat radiating blower 40. The temperature rise due to energization of each member is suppressed.

FIG. 4 is a front perspective view of the aging chamber 100 according to the first embodiment in a state where the door 3 is opened. FIG. 5 is a front perspective view of the state in which the door 3 of the aging chamber 100 according to the first embodiment is opened, as viewed from below. The aging chamber 100 is provided with an aging chamber 11. The aging chamber 11 is a space defined by a metal wall provided inside the housing 10. In this embodiment, the metal wall constituting the aging chamber 11 has a left side wall 12, a right side wall 13, a ceiling 14, a bottom 15, and a rear wall 16 (see FIG. 6). The wall defining the aging chamber 11 is preferably made of a material having high thermal conductivity and reflecting electromagnetic waves, such as aluminum or copper.

The door 3 is a hinged door. The left side of the door 3 is rotatably supported with respect to the housing 10, and the door 3 covers the aging chamber 11 so as to be openable and closable. In order to keep the door 3 closed, a lock mechanism for fixing the door 3 and the housing 10 may be provided. Further, the door 3 may be of a pull-out type, but it is preferable to provide a lock mechanism so that a gap does not occur between the door 3 and the housing 10 when the door 3 is closed.

A sealing material 3a, an electromagnetic wave shielding means 3b, and an electromagnetic wave reflector 3c are provided on the inner surface of the door 3. The sealing material 3a is provided in an annular shape along the inner edge of the door 3, and closes the door 3 and the housing 10 in an airtight state when the door 3 is closed. The sealing material 3a is made of an elastic material having adhesiveness. Preferably, as the sealing material 3a, a rubber-based material or a soft resin material, which is a material having a lower thermal conductivity and higher adhesion than the metal wall defining the aging chamber 11, is used. The inside of the sealing material 3a is provided with air bubbles or voids.

The electromagnetic wave shielding means 3b is a member that prevents the electromagnetic waves radiated into the aging chamber 11 from propagating to the outside of the door 3. The electromagnetic wave shielding means 3b is composed of, for example, a material that absorbs electromagnetic waves arranged in a ring shape along the inner edge of the door 3. Alternatively, the electromagnetic wave shielding means 3b has a choke structure. The electromagnetic wave shielding means 3b may be provided on the outer peripheral side of the door 3 with respect to the sealing material 3a, or may be provided on the inner peripheral side of the door 3 with respect to the sealing material 3a.

The electromagnetic wave reflector 3c is a member that reflects the electromagnetic wave radiated in the aging chamber 11, and is, for example, a metal plate such as aluminum or copper. The electromagnetic wave reflector 3c is larger than the opening on the front surface of the housing 10, and the electromagnetic wave reflector 3c covers the front opening of the housing 10 when the door 3 is closed. Therefore, the electromagnetic wave radiated in the aging chamber 11 is reflected by the electromagnetic wave reflector 3c, and the leakage of the electromagnetic wave from the aging chamber 11 to the outside of the door 3 can be suppressed. The electromagnetic wave reflector 3c is provided inside the sealing material 3a and the electromagnetic wave shielding means 3b. Therefore, it is possible to suppress heat leakage and dew condensation to the outside of the housing 10 via the electromagnetic wave reflector 3c, and to improve the cooling efficiency in the aging chamber 11. Further, even when dew condensation occurs on the electromagnetic wave reflector 3c, since the periphery of the electromagnetic wave reflector 3c is surrounded by the sealing material 3a, it is possible to suppress the outflow of dew condensation water to the outside of the housing 10.

In FIG. 4, the aged product 200 housed in the aging chamber 11 is also shown. The aged product 200 is placed on the first mounting plate 60. A support 17 for supporting the first mounting plate 60 is provided on the left side wall 12 constituting the aging chamber 11.

The first mounting plate 60 is made of a material such as polystyrene resin that does not easily absorb electromagnetic waves. Therefore, even if the aging chamber 11 is irradiated with electromagnetic waves, the heat generated by the first mounting plate 60 is small, and the heat of the first mounting plate 60 does not easily affect the cooling of the aging chamber 11. The first mounting plate 60 is provided with a vent 61 that penetrates vertically. Therefore, air flows through the vent 61 between the upper side and the lower side of the first mounting plate 60. By providing the vent 61 in this way, air moves above and below the first mounting plate 60, and the first mounting plate 60 does not hinder the equalization of the temperature in the aging chamber 11.

The front-rear dimension of the first mounting plate 60 is smaller than the inner dimension of the aging chamber 11 in the front-rear direction. There is a gap between the rear end of the first mounting plate 60 and the rear wall 16 (see FIG. 6) of the aging chamber 11, and when the door 3 is closed, the front end of the first mounting plate 60 There is also a gap between it and the door 3 (see FIG. 7). Since air can move above and below the first mounting plate 60 through these gaps, the non-uniformity of temperature in the aging chamber 11 is reduced.

The support 17 supports the first mounting plate 60 from below. The support 17 of the present embodiment is provided on the left side wall 12 and the right side wall 13, and is composed of ridges extending in the front-rear direction. In the present embodiment, a plurality of supports 17 are provided, but the number of supports 17 is not limited to the one shown in the figure, and may be one. By arranging the plurality of supports 17 vertically, the position of the first mounting plate 60 can be selected according to the size of the aged product 200, and the plurality of mounting plates are provided in the aging chamber 11. You can also do it.

A first cover 64 is provided on the ceiling 14 of the aging chamber 11, and a second cover 65 is provided on the bottom 15.

A door open / close detecting means 66 is provided at a position on the front surface of the housing 10 where the door 3 comes into contact with the door 3 when the door 3 is closed. The door open / close detecting means 66 is, for example, a mechanical switch that switches on and off depending on the presence or absence of contact with the door 3. Alternatively, the door open / close detecting means 66 is a magnet switch that switches on and off depending on the proximity state of the magnet provided on the door 3. Alternatively, the door open / close detecting means 66 is a distance sensor that detects the distance from the door 3. The door open / close detecting means 66 outputs a signal indicating whether or not the door 3 is closed to the control circuit 50.

The aging chamber 11 is provided with an infrared sensor 51 and a temperature sensor 52. The infrared sensor 51 is provided in the upper part of the aging chamber 11 and measures the surface temperature of the aged product 200 by detecting the infrared energy radiated from the aged product 200. In the present embodiment, the infrared sensor 51 is provided at the corner where the ceiling 14 and the right side wall 13 meet.

The temperature sensor 52 measures the air temperature of the aging chamber 11. In the present embodiment, the temperature sensor 52 is provided on the right side wall 13 of the aging chamber 11. The temperature sensor 52 is provided on the front side of the center of the aging chamber 11 in the front-rear direction. The temperature of the front side of the aging chamber 11 tends to fluctuate when the door 3 is opened. A temperature sensor 52 is provided at a position where this temperature fluctuation is likely to occur, and the cooling of the aging chamber 11 is controlled based on the air temperature of the aging chamber 11 detected by the temperature sensor 52, whereby the temperature of the aging chamber 11 is set to a set temperature. Can be approached with high accuracy.

FIG. 6 is a schematic vertical cross-sectional view of the aging chamber 100 according to the first embodiment in the left-right direction. FIG. 6 shows a state in which the second mounting plate 62 is arranged in the aging chamber 11 in addition to the first mounting plate 60. The structure of the second mounting plate 62 is the same as that of the first mounting plate 60, and the second mounting plate 62 is provided with a vent 63 that vertically penetrates the second mounting plate 62. There is.

A heat insulating material 67 is provided between the housing 10 and the left side wall 12, the right side wall 13, the ceiling 14, and the bottom 15. The heat insulating material 67 is made of a material having a lower thermal conductivity than the housing 10, the left side wall 12, the right side wall 13, the ceiling 14, and the bottom 15. The heat insulating material 67 is made of, for example, urethane foam or glass wool. By providing the heat insulating material 67, heat conduction inside and outside the aging chamber 11 is suppressed, so that it is possible to suppress a decrease in the cooling efficiency of the aging chamber 11, thereby reducing the power consumption associated with the cooling of the aging chamber 11. can do.

The rear wall 16 of the aging chamber 11 is provided with an aging chamber intake port 18. The aging chamber intake port 18 communicates with the decompression pump 41 shown in FIG. When the decompression pump 41 operates, the air in the aging chamber 11 is sucked into the decompression pump 41 through the aging chamber intake port 18. As a result, the pressure inside the aging chamber 11 is reduced.

The ceiling 14 of the aging chamber 11 is provided with a first electromagnetic wave irradiating body 21 of the first electromagnetic wave irradiating means 20. The first electromagnetic wave irradiating body 21 is a member that radiates electromagnetic waves into the aging chamber 11, is arranged so as to project from the ceiling 14 into the aging chamber 11, and is covered by the first cover 64. An electromagnetic wave transmitting body 23 is connected to the first electromagnetic wave irradiating body 21. The bottom 15 of the aging chamber 11 is provided with a second electromagnetic wave irradiating body 26 of the second electromagnetic wave irradiating means 25. The second electromagnetic wave irradiating body 26 is a member that radiates electromagnetic waves into the aging chamber 11, is arranged so as to project from the bottom 15 into the aging chamber 11, and is covered by the second cover 65. The second electromagnetic wave irradiator 26 is covered with the second cover 65. Details of the structure and function of the first electromagnetic wave irradiating means 20 and the second electromagnetic wave irradiating means 25 will be described later.

The first cover 64 that covers the first electromagnetic wave irradiator 21 suppresses dew condensation and adhesion of frost and the like to the first electromagnetic wave irradiator 21, and the second cover 65 that covers the second electromagnetic wave irradiator 26 is the second electromagnetic wave irradiation. It suppresses the adhesion of dew condensation and frost on the body 26. Since dew condensation and frost are unlikely to adhere to the first electromagnetic wave irradiator 21 and the second electromagnetic wave irradiator 26, the first electromagnetic wave irradiator 21 and the second electromagnetic wave irradiator 26 suppress fluctuations in the electromagnetic wave irradiation characteristics, and also. Since dirt and corrosion are suppressed, electrical troubles are less likely to occur.

The first cover 64 and the second cover 65 are made of a material such as polystyrene resin or ceramics that does not easily absorb electromagnetic waves. Therefore, even if the aging chamber 11 is irradiated with electromagnetic waves, the heat generated by the first cover 64 and the second cover 65 is small, and the heat of the first cover 64 and the second cover 65 does not easily affect the cooling of the aging chamber 11. ..

The vertical cross-sectional shape of the first cover 64 in the left-right direction is a tapered shape that tapers from the base attached to the ceiling 14 toward the tip. Further, the vertical cross-sectional shape of the second cover 65 in the left-right direction is a tapered shape that tapers from the base portion attached to the first and bottom 15 toward the tip. Since the side surfaces of the first cover 64 and the second cover 65 are inclined surfaces or inclined curved surfaces in this way, dew condensation water or frost adhering to the first cover 64 and the second cover 65 easily flows downward, and the first cover 1 It is difficult to be held on the surfaces of the cover 64 and the second cover 65. Further, even when the drip falls from the aged product 200, the drip easily flows on the surface of the second cover 65 and falls to the bottom 15, and the drip is difficult to be held by the second cover 65. Therefore, it is possible to reduce the influence of the moisture adhering to the first cover 64 and the second cover 65 on the electromagnetic wave irradiation into the aging chamber 11 due to the absorption of the electromagnetic wave.

The bottom 15 may be provided with a drain hole that communicates with the outside of the aging chamber 11. By providing the drain hole, the dew condensation water or the drip that has fallen to the bottom 15 can be discharged to the outside of the aging chamber 11, so that the hygiene inside the aging chamber 11 can be improved. When the bottom 15 is provided with a drainage hole, the bottom 15 may be provided with an inclination that descends toward the drainage hole.

A cooling plate 33 and a cooling plate 38 are attached to the back surface of the rear wall 16 of the aging chamber 11, that is, the surface of the rear wall 16 opposite to the aging chamber 11. In FIG. 6, the cooling plate 33 and the cooling plate 38 are shown by broken lines. The functions and structures of the cooling plate 33 and the cooling plate 38 will be described later.

FIG. 7 is a schematic vertical cross-sectional view of the aging chamber 100 according to the first embodiment in the front-rear direction. FIG. 7 shows a cross section of the pressure reducing pump 41 through the suction pipe 411. The above-mentioned heat insulating material 67 is also provided inside the outer shell of the door 3.

The decompression pump 41 has a suction pipe 411. The suction pipe 411 is connected to the aging chamber intake port 18 provided on the rear wall 16 of the aging chamber 11. The decompression pump 41 sucks the air in the aging chamber 11 through the aging chamber intake port 18 and the suction pipe 411, and brings the inside of the aging chamber 11 closer to a vacuum state. The suction tube 411 is preferably made of a material having a strength that does not collapse even in a reduced pressure state. Further, the suction tube 411 is preferably made of a material having a lower thermal conductivity than the wall of the aging chamber 11. By doing so, it is possible to suppress heat leakage of the aging chamber 11 via the suction pipe 411. The suction tube 411 is made of, for example, a synthetic resin.

The suction tube 411 is provided with a pressure sensor 53. The pressure sensor 53 detects the pressure in the suction tube 411, that is, the pressure in the aging chamber 11. A signal based on the pressure detected by the pressure sensor 53 is input to the control circuit 50.

The antenna constituting the first electromagnetic wave irradiator 21 and the second electromagnetic wave irradiator 26 may be configured to rotate about a rotation axis.

The electromagnetic wave generator 22 and the electromagnetic wave generator 27 are devices that generate electromagnetic waves. The electromagnetic wave generator 22 and the electromagnetic wave generator 27 of the present embodiment have a semiconductor type transmitter. The semiconductor transmitter has a wide bandgap semiconductor such as GaN (gallium nitride) or LDMOS (Laterally Diffused MOS), and generates microwaves having a frequency of about 2.45 GHz. The frequency of the electromagnetic wave generated from the magnetron is distributed in the range of about 2.45 ± 0.2 GHz, but the frequency of the electromagnetic wave generated from the semiconductor transmitter is a stable frequency with almost no fluctuation with respect to 2.45 GHz. be. Further, the semiconductor type transmitter is different from the magnetron in that the frequency can be variably controlled. By adopting a semiconductor type transmitter for the electromagnetic wave generator 22 and the electromagnetic wave generator 27, the phase of the generated electromagnetic wave can be precisely controlled. Therefore, the temperature of the food irradiated with the electromagnetic wave can be precisely controlled. The electromagnetic wave generator 22 and the electromagnetic wave generator 27 may be of a magnetron type.

The electromagnetic wave transmission body 23 and the electromagnetic wave transmission body 28 are members for carrying electromagnetic waves, and are, for example, coaxial cables or waveguides. The electromagnetic wave generated by the electromagnetic wave generator 22 is transmitted to the first electromagnetic wave irradiating body 21 via the electromagnetic wave transmitting body 23. The electromagnetic wave generated by the electromagnetic wave generator 27 is transmitted to the second electromagnetic wave irradiating body 26 via the electromagnetic wave transmitting body 28. The electromagnetic wave transmitter 23 and the electromagnetic wave transmitter 28 include an insulator such as polyethylene or fluororesin.

(First cooling means 30 and second cooling means 35)
The first cooling means 30 includes a heat radiating fin 31, a Pelche element 32, a cooling plate 33, and a heat radiating plate 34.

The Pelche element 32 is an element that absorbs heat from one surface by energization and dissipates heat from the other surface. One surface of the Pelche element 32 is thermally connected to the cooling plate 33 which is a cooling body, and the other surface of the Pelche element 32 is thermally connected to the heat dissipation plate 34. The cooling plate 33 and the heat radiating plate 34 are made of a metal such as aluminum having high thermal conductivity. It is preferable that heat conductive grease is arranged on the connection surface between the Pelche element 32 and the cooling plate 33 and the connection surface between the Pelche element 32 and the heat dissipation plate 34. The heat radiating plate 34 is thermally connected to the radiating fin 31. The heat radiating plate 34 dissipates heat to the air via the radiating fins 31.

The second cooling means 35 includes a heat radiating fin 36, a Pelche element 37, a cooling plate 38, and a heat radiating plate 39. The heat radiating fin 36, the Pelche element 37, the cooling plate 38, and the heat radiating plate 39 have the same functions and structures as the heat radiating fin 31, the Pelche element 32, the cooling plate 33, and the heat radiating plate 34, respectively.

In the present embodiment, a heat transfer plate 68 is provided between the cooling plate 33 and the cooling plate 38 and the rear wall 16. The heat transfer plate 68 is a plate made of a material having high thermal conductivity such as aluminum or copper, and is arranged along the upper and lower sides of the back surface of the rear wall 16. The cooling plate 33 and the cooling plate 38 are thermally connected to the heat transfer plate 68. The cooling plate 33 and the cooling plate 38 may be brought into direct contact with the wall of the aging chamber 11 without providing the heat transfer plate 68.

When the Pelche element 32 and the Pelche element 37 are energized, the air in the aging chamber 11 is cooled through the cooling plate 33, the cooling plate 38, the heat transfer plate 68, and the rear wall 16. In the aging chamber 11, the air around the rear wall 16 where the heat transfer plate 68 is directly connected is first cooled, and the temperature difference generated between the cooled air and other air causes convection. Occurs. Then, the entire aging chamber 11 is cooled by the convection of air.

The aging chamber intake port 18 is preferably provided above the aging chamber 11. More preferably, it is provided above the cooling plate 33, the cooling plate 38 and the heat transfer plate 68. By doing so, the low-temperature air cooled via the cooling plate 33, the cooling plate 38, and the heat transfer plate 68 and heading downward due to convection is less likely to be sucked into the decompression pump 41. Therefore, it is possible to suppress a decrease in cooling efficiency in the aging chamber 11.

Further, in the present embodiment, the first cooling means 30 and the second cooling means 35 using the Pelche element 32 and the Pelche element 37 as a cooling heat source are shown, but a compressor type cooling device may be used. In this case, the cooler may be thermally connected to the heat transfer plate 68.

(Operation of aging warehouse 100)
Hereinafter, the operation of the aging chamber 100 will be described. When the operation start instruction in the aging chamber 100 is input to the operation unit 2, the control circuit 50 detects whether or not the door 3 is closed based on the output from the door open / close detecting means 66. When it is detected that the door 3 is open, the display unit 1 notifies the user to close the door 3. When it is detected that the door 3 is closed, the control circuit 50 operates the first electromagnetic wave irradiating means 20, the second electromagnetic wave irradiating means 25, and the first cooling means 30 and the second cooling means 35.

When the aged product 200 is aged in the aging chamber 100, the aged product 200 is heated by the first electromagnetic wave irradiating means 20 and the second electromagnetic wave irradiating means 25 so that the following temperature conditions are satisfied, and the aged product 200 is first. The aging chamber 11 is cooled by the cooling means 30 and the second cooling means 35.
-Internal temperature of the aged product 200: about 7 ° C to about 15 ° C
-Surface temperature of the aged product 200: about 0 ° C to about 3 ° C
-Air temperature of the aging chamber 11: about -5 ° C to about 10 ° C
The internal temperature of the aged product 200 is the temperature at which the enzyme is activated. The surface temperature of the aged product 200 is a so-called chilled temperature zone, which is a temperature at which the growth of fungi, molds and the like is suppressed. The air temperature of the aging chamber 11 is a temperature at which the internal temperature and the surface temperature of the aged product 200 are balanced.

The surface temperature of the aged product 200 is measured based on the amount of infrared energy detected by the infrared sensor 51. The internal temperature of the aged product 200 is the amount of change in the surface temperature measured by the infrared sensor 51 per unit time, the air temperature of the aging chamber 11 measured by the temperature sensor 52, and the heat absorption amount of the aged product 200. Is estimated by the control circuit 50. The heat absorption amount of the aged product 200 is the energy amount of the electromagnetic wave reflected and returned from the irradiation energy amount which is the energy amount of the electromagnetic wave radiated from the first electromagnetic wave irradiating means 20 and the second electromagnetic wave irradiating means 25. Obtained by subtracting the amount of energy. The amount of energy of the reflected and returned electromagnetic wave is detected, for example, based on the electric power detected by the electric power detection unit that extracts the electric power of the reflected wave reflected and returned from the aging chamber 11. The signal based on the electric power detected by the electric power detection unit is input to the control circuit 50. The control circuit 50 calculates the amount of energy of the electromagnetic wave reflected and returned by a predetermined algorithm based on the input signal. A temperature sensor having a rod-shaped member inserted into the aged product 200 may be provided, and the internal temperature of the aged product 200 may be directly measured using this temperature sensor.

The control circuit 50 estimates the load amount of the aged product 200 and the amount of heat dissipated from the surface from the amount of change in the surface temperature of the aged product 200 per unit time. For example, the temperature change of the surface of the aged product 200 per unit time is detected during the electromagnetic wave irradiation and the electromagnetic wave irradiation stop, and the load amount and the heat radiation amount of the aged product 200 are increased based on the difference in the temperature change. Guessed.

The control circuit 50 constantly monitors the internal temperature and surface temperature of the aged product 200 and the air temperature of the aging chamber 11. The control circuit 50 controls the outputs of the first electromagnetic wave irradiating means 20 and the second electromagnetic wave irradiating means 25 so that the internal temperature of the aged product 200 is maintained at a desired temperature. When the surface temperature of the aged product 200 rises too much, the control circuit 50 reduces or stops the outputs of the first electromagnetic wave irradiating means 20 and the second electromagnetic wave irradiating means 25. The outputs of the first electromagnetic wave irradiating means 20 and the second electromagnetic wave irradiating means 25 are individually controlled. Therefore, when the aged product 200 is placed on each of the first mounting plate 60 and the second mounting plate 62, the internal temperature of each aged product 200 can be controlled accurately.

When one of the first electromagnetic wave irradiating means 20 and the second electromagnetic wave irradiating means 25 is irradiating the electromagnetic wave, the control circuit 50 stops the irradiation of the electromagnetic wave or reduces the irradiation amount of the electromagnetic wave. That is, the irradiation of the electromagnetic wave from the upper side and the irradiation of the electromagnetic wave from the lower side are given priority alternately. By doing so, it is possible to suppress a decrease in heating accuracy due to the interaction between the electromagnetic wave from the first electromagnetic wave irradiating means 20 and the electromagnetic wave from the second electromagnetic wave irradiating means 25. When only one of the first mounting plate 60 and the second mounting plate 62 is used, electromagnetic waves are alternately and preferentially irradiated from the upper side and the lower side of the aged product 200. It is easy to maintain the entire inside of the aged product 200 at an appropriate aging temperature. When the aged product 200 is placed on both the first mounting plate 60 and the second mounting plate 62, the upper and lower aged products 200 are maintained at appropriate aging temperatures. It is easy to obtain a plurality of well-aged products 200 at the same time.

The control circuit 50 may make the frequencies and phases of the electromagnetic waves output from the first electromagnetic wave irradiating means 20 and the second electromagnetic wave irradiating means 25 different from each other. By doing so, the standing wave of the electromagnetic wave formed in the aging chamber 11 changes more greatly. Therefore, even if the degree of absorption of the electromagnetic wave differs depending on the part of the aged product 200, each part of the aged product 200 tends to absorb the electromagnetic wave at any timing due to the change of the standing wave of the electromagnetic wave. Therefore, the absorption efficiency of the electromagnetic wave of the aged product 200 can be enhanced, and the uneven absorption of the electromagnetic wave can be suppressed.

Since the inner wall of the aging chamber 11 is made of a material that reflects electromagnetic waves, the electromagnetic waves radiated from the first electromagnetic wave irradiating body 21 and the second electromagnetic wave irradiating body 26 are reflected by the inner wall. Due to the reflected electromagnetic wave, the aged product 200 is irradiated with electromagnetic waves from all directions. As a result, the heating efficiency of the aged product 200 is improved, the unevenness of the internal temperature is reduced, and the internal temperature of the aged product 200 can be brought close to uniform.

While the aged product 200 is heated by the first electromagnetic wave irradiating means 20 and the second electromagnetic wave irradiating means 25, the inside of the aging chamber 11 is cooled by the first cooling means 30 and the second cooling means 35. When the first cooling means 30 and the second cooling means 35 operate, the rear wall 16 is cooled via the heat transfer plate 68. The heat transfer from the rear wall 16 to the air around the rear wall 16 cools the air around the rear wall 16, and the cooled air convects in the aging chamber 11 to cool the entire aging chamber 11. By cooling the inside of the aging chamber 11 to lower the surface temperature of the aged product 200, the growth of bacteria, mold and the like on the surface of the aged product 200 is suppressed. Further, the left side wall 12, the right side wall 13, the ceiling 14, the bottom 15 and the rear wall 16 defining the aging chamber 11 are made of a metal having excellent heat conduction. Therefore, heat conduction from the rear wall 16 to the left side wall 12, the right side wall 13, the ceiling 14 and the bottom 15 makes these temperatures more quickly uniform. By heat transfer from these cooled inner walls to the air, the temperature unevenness of the aging chamber 11 can be suppressed, and the surface temperature of the aged product 200 can be brought close to uniform.

When the first cooling means 30 and the second cooling means 35 are operating, the heat dissipation blower 40 operates. When the heat radiating blower 40 operates, the air sucked from the intake port 4 shown in FIG. 1 or 2 is sent to the heat radiating fins 31 and the heat radiating fins 36. The heat radiated from the heat radiating plate 34 is promoted through the heat radiating fins 31, and the heat radiated from the heat radiating plate 39 is promoted through the heat radiating fins 36. Therefore, the cooling performance of the first cooling means 30 and the second cooling means 35 is maintained.

When the first electromagnetic wave irradiating means 20, the second electromagnetic wave irradiating means 25, the first cooling means 30, and the second cooling means 35 are operating, the decompression pump 41 is operated at the same time to put the aging chamber 11 in the decompression state. You can also. Specifically, the decompression pump 41 is operated to suck the air in the aging chamber 11 and depressurize the inside of the aging chamber 11 to about 0.7 atm, which is lower than the atmospheric pressure. The operation of the pressure reducing pump 41 is controlled by the control circuit 50 based on the pressure of the aging chamber 11 detected by the pressure sensor 53. By depressurizing the aging chamber 11 and bringing it closer to a vacuum in this way, oxidation and putrefaction of the aged product 200 can be further suppressed as compared with the case where the inside of the aging chamber 11 is cooled at normal pressure. Therefore, the yield of the aged product 200 can be further improved.

Since the first mounting plate 60 is provided with a vent 61 and the second mounting plate 62 is provided with a vent 63, the first mounting plate 60 and the second mounting plate 62 are in the aging chamber. It is difficult to obstruct the upper and lower convection of the air of 11. Therefore, the temperature of the aging chamber 11 can be brought closer to more uniform. Further, as shown in FIG. 7, a gap is provided between the front end of the first mounting plate 60 and the door 3, and between the rear end and the rear wall 16. Further, a gap is provided between the front end of the second mounting plate 62 and the door 3, and between the rear end and the rear wall 16. Due to these gaps, air easily convection in the aging chamber 11, so that the temperature of the aging chamber 11 can be brought closer to the temperature more quickly and uniformly.

When the control circuit 50 detects that the door 3 is opened while the first electromagnetic wave irradiating means 20 and the second electromagnetic wave irradiating means 25 are irradiating the electromagnetic waves, the control circuit 50 detects the first electromagnetic wave irradiating means 20 and The operation of the second electromagnetic wave irradiation means 25 is stopped. This makes it possible to prevent the leakage of electromagnetic waves to the outside of the aging chamber 100. After stopping the irradiation of the electromagnetic wave due to the opening of the door 3, when it is detected that the door 3 is closed, the irradiation of the electromagnetic wave is restarted.

Further, when it is detected that the door 3 is opened following the irradiation of the electromagnetic wave by the first electromagnetic wave irradiating means 20 and the second electromagnetic wave irradiating means 25, the first cooling means 30 and the second cooling means 35 are used. , The cooling capacity in the aging chamber 11 may be improved to continue cooling. By doing so, even when the user opens the door 3 to check the state of the aged product 200, it is possible to suppress an increase in the surface temperature of the aged product 200. Further, when the door 3 is closed, the cooling capacity of the first cooling means 30 and the second cooling means 35 is improved until the air temperature of the aging chamber 11 reaches a predetermined temperature. May be maintained. By doing so, even if the air temperature of the aging chamber 11 rises due to the opening of the door 3, the air temperature of the aging chamber 11 can be returned to a predetermined temperature more quickly.

As described above, the aging chamber 100 of the present embodiment includes a aging chamber 11 formed of a metal left side wall 12, a right side wall 13, a ceiling 14, a bottom 15, and a rear wall 16. Further, the aging chamber 100 includes a first electromagnetic wave irradiator 21 and a second electromagnetic wave irradiator 26 as electromagnetic wave irradiators that irradiate the aging chamber 11 with electromagnetic waves. Further, the first cooling means 30 and the second cooling means 35 having a cooling plate 33 or a cooling plate 38 which is a cooling body electrically conductively connected to the rear wall 16 which is one of the walls of the aging chamber 11 are provided. rice field. Since the first cooling means 30 and the second cooling means 35 connected to the rear wall 16 of the aging chamber 11 so as to conduct heat are provided, the rear wall 16 of the aging chamber 11 is cooled, and the inside of the aging chamber 11 is cooled from the rear wall 16. The inside of the aging chamber 11 can be cooled by heat transfer to the air. The air in the aging chamber 11 is cooled as a whole by natural convection. Since cold air is not forcibly blown to the aged product 200, drying in the aging chamber 11 is suppressed, and the yield when obtaining the aged product 200 can be improved. Further, in Patent Document 1, a double structure of a heating chamber and a cooling chamber is provided, but in the present embodiment, the aging chamber 11 also serves as a heating chamber and a cooling chamber of the aged product 200, and is aged. The structure of the storage 100 is simplified as compared with the double structure of Patent Document 1. Therefore, the manufacturing cost of the aging chamber 100 can be reduced.

Further, in the present embodiment, the cooling plate 33 of the first cooling means 30 and the cooling plate 38 of the second cooling means 35 are electrically conductively connected to the rear wall 16 facing the door 3. If the door 3 is opened while the aging chamber 11 is in the cooled state, the temperature in the vicinity of the door 3 of the aging chamber 11 tends to rise, but in the present embodiment, the door 3, the cooling plate 33, and the cooling plate 38 are separated from each other. Since they are separated from each other, the air temperature of the rear wall 16 and its surroundings is unlikely to decrease. Therefore, after the door 3 is closed, the air temperature of the aging chamber 11 can be brought closer to the set temperature, whereby the surface temperature of the aged product 200 can be quickly lowered to suppress the growth of fungi and mold. Can be done.

Further, in the present embodiment, the first electromagnetic wave irradiator 21 and the second electromagnetic wave irradiator 26 are provided on the ceiling 14 and the bottom 15 which are the facing walls of the aging chamber 11, respectively. That is, the first electromagnetic wave irradiator 21 is arranged on the ceiling 14 side, which is one region, and the second electromagnetic wave irradiator 26 is provided on the bottom 15 side, which is the other region, with the first mounting plate 60 as a boundary. The ceiling 14 and the bottom 15 are substantially parallel to the flat plate surface of the first mounting plate 60 or the second mounting plate 62 on which the aged product 200 is placed. Therefore, uneven irradiation of electromagnetic waves to the aged product 200 mounted on the first mounting plate 60 or the second mounting plate 62 can be reduced. Therefore, the internal temperature of the aged product 200 can be brought closer to more uniform, and the aged product 200 can be aged well. Further, since electromagnetic waves can be irradiated from both above and below the first mounting plate 60 and the second mounting plate 62, it is possible to suppress the heating unevenness of the aged product 200 and obtain a good aging effect with less aging unevenness. can.

Embodiment 2.
In the aging chamber 100 of the present embodiment, the arrangement of the first electromagnetic wave irradiating means 20 and the second electromagnetic wave irradiating means 25 is different from that of the first embodiment. Further, the aging chamber 100 of the present embodiment includes a stirring device 70 that agitates the air in the aging chamber 11. In this embodiment, the differences from the first embodiment will be mainly described.

FIG. 8 is a schematic vertical cross-sectional view of the aging chamber 100 according to the second embodiment in the left-right direction. FIG. 9 is a schematic vertical cross-sectional view of the aging chamber 100 according to the second embodiment in the front-rear direction. 8 and 9 show an example in which only the first mounting plate 60 is provided, but the second mounting plate 62 may also be arranged in the aging chamber 11 as in the first embodiment.

In the present embodiment, the first electromagnetic wave irradiating means 20 and the second electromagnetic wave irradiating means 25 are provided on the ceiling 14 of the aging chamber 11. Specifically, the first electromagnetic wave irradiator 21 and the second electromagnetic wave irradiator 26 are provided so as to project from the ceiling 14 to the aging chamber 11, and the electromagnetic wave transmitters 23 and 28 and the electromagnetic wave generator 22 are provided above the ceiling 14. , 27 are provided. As described above, in the present embodiment, since the first electromagnetic wave irradiator 21 and the second electromagnetic wave irradiator 26 are arranged in the upper part of the aging chamber 11 and the electromagnetic wave irradiator is not provided in the bottom 15, the electromagnetic wave irradiator falls to the bottom 15. Condensation water or drip does not adhere to the electromagnetic wave irradiator. Therefore, it is possible to avoid troubles such as dew condensation water or drip adhering to the electromagnetic wave irradiating body absorbing the electromagnetic wave or lowering the electrical insulation property.

Further, as shown in FIG. 8, the center of the first mounting plate 60 in the left-right direction is located between the first electromagnetic wave irradiating body 21 and the second electromagnetic wave irradiating body 26 in the left-right direction. Further, in the present embodiment, as shown in FIG. 8, when the rear wall 16 is viewed from the front, the first electromagnetic wave irradiator 21 is located at a position substantially symmetrical with respect to the left and right centers of the first mounting plate 60. A second electromagnetic wave irradiator 26 is arranged. Therefore, the aged product 200 placed on the first mounting plate 60 can be irradiated with electromagnetic waves in a well-balanced manner from the left and right. As a result, the internal temperature of the aged product 200 can be brought closer to more uniform.

Further, as shown in FIG. 8, an infrared sensor 51 is provided between the first electromagnetic wave irradiating body 21 and the second electromagnetic wave irradiating body 26 in the left-right direction. The infrared sensor 51 is an angle where the rear wall 16 and the ceiling 14 intersect, and is arranged substantially in the center on the left and right. In the present embodiment, the first electromagnetic wave irradiating means 20 and the second electromagnetic wave irradiating means 25 are arranged in the upper part of the aging chamber 11, and in order to supply electromagnetic waves to the aged product 200 from above, the upper surface of the aged product 200 is provided. The temperature on the side tends to be high. Therefore, by arranging the infrared sensor 51 at a position where the temperature of the upper surface of the aged product 200 can be easily detected, the temperature detection accuracy of the upper surface of the aged product 200 is improved. Based on this accurately detected temperature, the first electromagnetic wave irradiating means 20, the second electromagnetic wave irradiating means 25, the first cooling means 30, and the second cooling means 35 are controlled, so that the fungus or mold of the aged product 200 is controlled. It is possible to suppress the growth of the aged product 200 and improve the yield of the aged product 200.

The agitator 70 is a blower that agitates either or both of the air and electromagnetic waves in the aging chamber 11. The stirring device 70 has a blade connected to the rotating shaft and a motor for rotating the rotating shaft. The stirring device 70 is the upper part and the rear part of the aging chamber 11, and is arranged substantially in the center of the left and right sides. In the present embodiment, the delivery surface from which the agitator 70 sends out air is provided on the lower surface of the agitator 70, and the delivery surface is the first mounting plate 60 and the rear wall as shown in FIG. It faces the gap between 16 and 16.

When the stirring device 70 operates, an air flow from top to bottom is formed in the rear part of the aging chamber 11. Then, the rear wall 16 connected to the first cooling means 30 and the second cooling means 35 promotes heat absorption from the air, and has the effect of increasing the cooling efficiency in the aging chamber 11. The airflow downward of the stirrer 70 passes through the gap between the first mounting plate 60 and the rear wall 16 and flows along the rear wall 16 to reach the bottom 15 and forward along the bottom 15. And head for door 3. Then, air flows upward along the door 3, and air flows in the space between the first mounting plate 60 and the door 3. The air that flows upward along the door 3 and reaches the ceiling 14 flows backward along the ceiling 14 and is sucked into the stirring device 70. In this way, since the air flow circulating in the aging chamber 11 is formed by the stirring device 70, the non-uniformity of the air temperature in the aging chamber 11 is alleviated, and the temperature in the aging chamber 11 is brought closer to more uniform. be able to. Therefore, it is possible to improve the aging finish of the aged product 200.

Further, as shown in FIG. 9, the aging chamber 100 of the present embodiment does not include the heat transfer plate 68 provided in the first embodiment. Then, the substantially central portion of the rear wall 16 in the vertical direction is recessed toward the rear. This recessed portion is referred to as a recess 161. The recess 161 is located below the delivery surface of the stirring device 70, and is provided at a position where the stirring device 70 and the recess 161 overlap each other in the left-right direction when the rear wall 16 is viewed from the front as shown in FIG. ing. The cooling plate 33 and the cooling plate 38 are thermally connected to the portion of the rear wall 16 corresponding to the recess 161. Since the recess 161 is provided, a space corresponding to the depth of the recess 161 is formed in front of the rear wall 16 which is cooled by heat conduction from the cooling plate 33 and the cooling plate 38, and the air in this space is cooled. To. Then, the cooled air in the space formed by the recess 161 flows downward by the action of the stirring device 70. In this way, by providing the recess 161 to increase the amount of cooled air, the inside of the aging chamber 11 can be brought closer uniformly.

As shown in FIG. 9, the temperature sensor 52 of the present embodiment is arranged between the front end of the first mounting plate 60 and the door 3. Therefore, the temperature sensor 52 can detect the temperature of the air circulating upward along the door 3 by the operation of the stirring device 70, and the detection accuracy of the air temperature of the aging chamber 11 is improved.

The blades of the agitator 70 may be made of a material that reflects or refracts electromagnetic waves. By doing so, when the blades of the stirring device 70 rotate, the electromagnetic waves in the aging chamber 11 are agitated, and the intensity distribution of the electromagnetic waves in the aging chamber 11 can be changed. As a result, heating of the aged product 200 due to local electromagnetic waves is reduced, and uneven heating of the aged product 200 is suppressed, so that the aged product 200 can be matured satisfactorily. In this embodiment, an example in which the stirring device 70 is a blower that stirs the air in the aging chamber 11 will be described, but the stirring device 70 does not actively stir the air but stirs the electromagnetic waves. May be. In this case, for example, the blades of the stirring device 70, which is the blower described in the present embodiment, are made of a material that reflects or refracts electromagnetic waves, and are operated by reducing the rotation speed. By suppressing the blowing action of the stirring device 70 in this way, it is possible to suppress the stirring action of the air in the aging chamber 11 and obtain the stirring action of the electromagnetic wave. Further, the stirring device 70 may be formed of a rod-shaped member made of a material that reflects or refracts electromagnetic waves radiating from the outer periphery of the rotating shaft. By rotating such a rod-shaped member, it is possible to obtain the stirring action of electromagnetic waves while suppressing the stirring action of air by the stirring device 70.

As described above, the aging chamber 100 of the present embodiment is provided with a stirring device 70 that agitates either or both of the air and electromagnetic waves of the aging chamber 11. Therefore, since the air flow circulating in the aging chamber 11 can be formed, the temperature unevenness of the aging chamber 11 can be suppressed and the surface of the aged product 200 can be cooled evenly. Further, the stirring device 70 of the present embodiment sends air between the first mounting plate 60 on which the aged product 200 is placed and the wall of the aging chamber 11, and directly on the aged product 200. It is difficult to blow air. Therefore, the airflow formed by the stirring device 70 makes it difficult for the aged product 200 to dry, and it is difficult for the yield of the aged product 200 to decrease. Further, in the present embodiment, the surface temperature of the aged product 200 can be quickly lowered by circulating the cold air with the stirring device 70. Therefore, even if the aged product 200 has a small capacity and the difference between the surface temperature and the internal temperature is small, it becomes easy to keep the inside at about 10 ° C. and promote the enzyme activity while keeping the surface at about 0 ° C. .. As described above, according to the present embodiment, the finish of aging can be improved regardless of the size of the aged product 200. Further, since the stirring device 70 agitates the electromagnetic waves in the aging chamber 11 to change the intensity distribution of the electromagnetic waves in the aging chamber 11, it is possible to suppress uneven heating of the aged product 200.

Further, the first electromagnetic wave irradiating means 20 and the second electromagnetic wave irradiating means 25 were collectively arranged in the upper part of the aging chamber 100. The control circuit 50 is also arranged at the rear and above the aging chamber 100. Therefore, since the wiring between the first electromagnetic wave irradiating means 20 and the second electromagnetic wave irradiating means 25 and the control circuit 50 can be shortened, the assembleability of the aging chamber 100 can be improved and the manufacturing cost can be reduced.

Embodiment 3.
In the aging chamber 100 of the present embodiment, the arrangement of the first electromagnetic wave irradiating means 20 and the second electromagnetic wave irradiating means 25 is different from that of the first embodiment and the second embodiment. In this embodiment, the differences from the first embodiment will be mainly described.

FIG. 10 is a schematic vertical cross-sectional view of the aging chamber 100 according to the third embodiment in the left-right direction. FIG. 11 is a schematic vertical cross-sectional view of the aging chamber 100 according to the third embodiment in the front-rear direction.
