2. Description of the Related Art As a conventional heating / drying apparatus using microwaves, the apparatuses described in JP-A-01-260791 and JP-A-05-024601 are known. Among them, in the device described in Japanese Patent Application Laid-Open No. 01-260791, a magnetron and a waveguide are installed above and below a microwave shielding container, and a partition wall is provided between the shielding container lid and the magnetron and waveguide. The plate-like member provided with a hole at the bottom and the partition wall support the garbage. Further, a drainage pipe was provided at the bottom of the device, and a condensation mechanism was installed in the drainage pipe. This time,
The microwave generated from the magnetron heats the material to be dried to generate water vapor. This water vapor, together with the water exuding from the material to be dried, passes through a plate-shaped member having a hole at the bottom, reaches a condensing mechanism provided in the drain pipe, and is condensed. In this configuration, the lower portion of the microwave shielding container is connected to the drain pipe through the plate-shaped member having the lower hole. On the other hand, in the apparatus described in Japanese Patent Laid-Open No. 05-024601, the waste container is located inside the condensing container, and a plurality of vent holes are provided on the side surface of the waste container. Further, the waste container is made of a microwave transmitting material and the condensing container is made of a microwave reflecting material, and all of them are arranged in the processing chamber. At this time, a condensed water outflow hole was provided in the lower part of the condensing container made of the microwave reflecting material, and a condensed water trap was provided below it. Further, a microwave oscillator and a waveguide are connected to the processing chamber, a fan for sending air into the waste container through the outer wall of the condensing container is attached, and a deodorizing mechanism is provided at the exhaust port. It was At this time, the microwave generated from the microwave transmitter is sent to the waste storage container, heats the material to be dried stored therein to generate water vapor, and the generated water vapor is generated on the outer periphery of the waste storage container. It was configured to condense on the wall surface of the condensing container composed of the installed microwave reflecting material. In this configuration, microwaves can reach the condensed water trap not only inside the condensing container made of the microwave reflecting material, but also through the condensed water outflow hole provided in the lower part of the condensing container.

[0003]

In the above prior art, no consideration is given to preventing reheating of condensed water.
The device described in Japanese Patent Application Laid-Open No. 01-260791 has a structure in which microwaves pass from a lower portion of the microwave shielding container, pass through a plate-shaped member having a hole, enter a drain pipe, and reach a condensation mechanism. It was Therefore, the water that has passed through the lower plate-shaped member to reach the condensation mechanism provided in the drainage pipe and is condensed is reheated by the microwave and evaporated again, and the plate-shaped member with holes is opened. It passes through the member, flows back to the material to be dried, and flows out from the drain pipe as water vapor to the outside. Therefore, the drying efficiency of the material to be dried decreases,
There is a problem that the condensing mechanism provided for condensing the water vapor and the fan for cooling the condensing mechanism do not make sense. Further, in the device described in Japanese Patent Application Laid-Open No. 05-024601, the microwave is not only inside the condensing container made of the microwave reflecting material, but also through the condensed water outflow hole provided in the lower part to the condensed water trap. The structure was reachable. Therefore, the water condensed inside the condensing container,
The water that has reached the condensed water trap through the condensed water outflow hole is reheated by the microwave, evaporates again, flows back to the material to be dried through the condensed water outflow hole, and flows out from the exhaust port as water vapor to the outside. For this reason, the drying efficiency of the material to be dried is reduced, and the condensing container provided to condense the water vapor and the fan for cooling the condensing container are meaningless, and further, the deodorizing mechanism installed at the exhaust port is not provided. There was a problem that it had an adverse effect. Further, in the above-described conventional technique, the condensed water is reheated to generate steam, which causes a problem that the humidity in the room rises due to the steam. That is, the water vapor generated from the condensation mechanism, the condensation container and the condensed water trap flows out to the outside,
While increasing the humidity in the room where the device is installed, condensation occurs in the room or inside the device, causing mold and the like on the room walls and inside the device, making it unsanitary and causing condensation within the device such as a short circuit. There is a problem in that it causes a device failure. An object of the present invention is to improve the drying efficiency of the material to be dried by preventing the generation of gas such as water vapor due to reheating of liquid such as condensed water. Another object of the present invention is to reduce the adverse effect on the deodorizing device by a gas such as steam generated by reheating condensed liquid such as water, and to maintain the capability of the installed deodorizing device. .

[0004]

Among the above objects, in order to improve the drying efficiency of the material to be dried by preventing the generation of water vapor due to the reheating of condensed water, a micro-device for heating the material to be dried. Heating and drying including a microwave generator that generates waves, a microwave shielding container that stores the material to be dried and that prevents the microwave from leaking to the outside, and a condenser that condenses gas generated during drying In the apparatus, the condenser is installed outside the microwave shielding container, is provided in the gas flow path from the microwave shielding container to the condenser, and is made of a material that does not transmit the microwave. One or a plurality of holes are provided, and a microwave shielding means for shielding microwaves is provided. Note that it is preferable to provide one or a plurality of holes each having a diameter or a side which is less than or equal to ¼ of the wavelength of microwaves, preferably less than or equal to 1/16. Further, among the above objects, in order to maintain the capacity of the installed deodorizing device by reducing the adverse effect on the deodorizing device due to the generated steam for reheating the condensed water, it is provided in the latter stage of the condenser. Then, it has a storage means for storing the condensed liquid and a deodorizing device provided in the latter stage of the condenser for deodorizing the uncondensed gas. At this time, by installing an ultraviolet lamp as a deodorizing device, it is possible to deodorize the odor by the generated ozone and also to decompose the odor component or the organic component dissolved in the condensed liquid by ultraviolet rays.

[0005]

Function: A condenser (for example,
By installing a condensed water trap or the like), condensed water (the gas to be condensed is not limited to water, but the case of water will be described below) can be used, but in the present invention, the condensed water is reheated. In order to prevent this, a shielding means is provided.
Microwaves are on metal walls (including, but not limited to shielding means,
In the following, the case of a metal will be described), but if the diameter or one side of the hole formed in the metal wall is equal to or less than a quarter wavelength of the microwave, the microwave transmission amount will decrease exponentially. If the diameter or one side of the hole formed in the metal wall is not more than 1/16 wavelength of the microwave, the amount of transmission of the microwave is usually reduced to a negligible amount.
The hole size is 2.45 GHz, which is often used for heating devices.
In the case of the microwave, one wavelength is about 12.4 cm, so if it is a quarter wavelength, it is about 3 cm, and if it is a 16th wavelength, it is about 8 mm. For this reason, a condenser is installed outside the microwave shielding container, and in the flow path to the condenser, at a wavelength equal to or shorter than a quarter wavelength of the microwave, preferably,
The shielding means provided with one or a plurality of holes having a diameter or a side equal to or less than 1/16 wavelength of the microwave was provided, and the generated water vapor was able to move from the microwave shielding container to the condenser. The microwave energy reaching the condenser heats the condensed water because the amount of transmission of the microwave is attenuated by one or more holes having a diameter or side of not more than a quarter wavelength of the microwave. Does not reach. Therefore, the shielding means functions as a selection filter that allows only water vapor to pass but does not allow microwaves to pass. By connecting the microwave shielding container to the condenser with a pipe, it is possible to prevent water vapor from leaking to the outside of the device from the space between the microwave shielding container and the condenser. Further, by providing a temperature difference so that the condenser has a low temperature, by providing a water vapor pressure difference between the condenser and the microwave shielding container, by moving the water vapor from the microwave shielding container to the condenser, Backflow of water vapor from the condenser to the microwave shielding container can be prevented. Also, since the condenser becomes a low temperature,
The steam can be converted into condensed water by the condenser, and the outflow of steam to the outside of the device can be prevented. In addition, whether the pipe provided between the microwave shielding container and the condenser should be shortened, that is, the distance between the microwave shielding container and the condenser should be reduced to increase the spatial change rate of water vapor pressure. , Install a steam transfer fan between the microwave shielding container and the condenser,
By providing the water vapor transfer fan in the microwave shielding container, it is possible to promote the movement of water vapor inside the microwave shielding container and improve the effect of preventing the reverse flow of water vapor from the condenser to the microwave shielding container. In addition, by installing a deodorizing device in the latter stage of the condenser, the odorous component that has moved from the microwave shielding container together with water vapor and splashes and was not condensed at the time of condensation is removed. As a result, the water vapor generated from the material to be dried is condensed by the condenser before coming to the deodorizing device, so that it is possible to prevent dew condensation on the deodorizing device without increasing the humidity around the deodorizing device. Thereby, when the deodorizing device is a catalyst or an adsorption type, it is possible to prevent dew condensation on the surface of the catalyst or the adsorbent, so that the catalyst or the adsorption performance can be maintained. Further, when the deodorizing device is an ozone generator or the like, it is possible to prevent the deodorizing performance from being deteriorated due to the combination of water vapor and generated ozone. Further, when the deodorizing device is an optical device applied, dew condensation on the optical device can be prevented, so that the path of light is not obstructed and the disassembling performance can be maintained. At this time, by providing the ultraviolet lamp as a deodorizing device at a position where it can also irradiate the gas condensed in the storage means, the generated ozone deodorizes the odor, and the odor components dissolved in the condensed water and It is also possible to decompose organic components with ultraviolet light.
