Description

Volume reduction/volume reduction processing device

The invention relates to a volume reduction/volume reduction processing device. In more detail, it relates to a volume reduction/volume reduction treatment device that can reduce the volume/volume of wastes containing water such as water-containing garbage.

In the past, in order to reduce the cost of disposing of waste generated in households, etc., technologies were developed to reduce the volume and volume of waste. If the volume and volume of garbage can be reduced, the transportation and combustion costs of garbage can be reduced, and the global warming gas can be further reduced. In addition, the space for storing garbage in the household can be reduced, and the preservation period for suppressing corruption can be lengthened to a certain extent. In this way, advantages such as reducing the number of garbage disposals can also be obtained.

For example, wastes containing water, such as water-containing garbage discharged from households, may produce bad odors due to corruption during storage. In order to solve this problem, a device for drying waste containing moisture by warm air has been developed (Patent Documents 1 and 2).

In the case of supplying warm air to the waste, there are methods of supplying the waste from the top surface and the method of supplying it from the bottom surface. Patent Documents 3 and 4 disclose the technology of supplying warm air from the bottom of the waste to dry the waste. .

In the technique of Patent Document 3, an air-permeable ventilating cage is stored inside a metal storage container that is not air-permeable. The warm air passing through the gap between the ventilating container and the ventilating cage enters the ventilating cage from the lower part of the ventilating cage. The inside becomes contact with the waste contained in the ventilating cage.

In the technique of Patent Document 4, a configuration is adopted in which air holes are provided only at the upper portion and the bottom of the cylindrical garbage storage/heating space, and heated air is supplied from the air holes at the bottom. [Literature technical literature] [Patent Literature]

Patent Document 1: Japanese Patent No. 5060669 Patent Document 2: Japanese Patent No. 5959129 Patent Document 3: Japanese Patent Application Publication No. 2001-153553 Patent Document 4: Japanese Patent Application Publication No. 5-96267

[Problem to be solved by the present invention]

However, in the technique of Patent Document 3, warm air is supplied from the upper part of the storage container, and the vent hole of the ventilating cage is also provided outside the bottom of the ventilating cage. In this way, even if a vent path is formed between the storage container and the ventilating cage, the warm air is easier to enter from the upper part or the side of the bag body, and it is difficult to supply the warm air from the lower part to the waste inside the bag body.

On the other hand, in the technology of Patent Document 4, it is possible to reliably supply warm air from below to the waste in the garbage storage/heating space. However, a heating element is provided near the garbage storage/heating space. Therefore, if moisture drips from the waste and contacts the heating element, it prevents the temperature of the heating element from rising. In this way, it is impossible to supply the warm air having the temperature required for drying of the waste into the garbage storage/heating space, and it is impossible to stably dry the waste. In addition, the water dripping from the waste is in a state of constant contact with the heating element, so there is a possibility of corrosion of the heating element.

As mentioned above, in the conventional device for drying waste by warm air, it is essentially difficult to supply warm air from the bottom of the container containing the waste to dry it, and such a device has not yet been developed in the current state of the art.

In view of the above phenomenon, the object of the present invention is to provide a weight reduction/volume reduction treatment device that can supply warm air from the bottom of the waste containing moisture to dry the waste, and in addition, can dry the waste in a small volume and effectively.

The processed object is dried by contacting the heated air with the processed object to reduce the volume and volume, and is characterized in that It can improve the drying efficiency of the processed objects.

In addition, the object to be processed by the weight reduction/volume reduction processing device of the present invention is not particularly limited. For example, water-containing garbage discharged from homes, etc. can be cited, but it is not limited to this form.

＜Volume reduction/volume reduction processing device 1＞ As shown in FIG. 1, the volume reduction/volume reduction processing device 1 of the present embodiment includes a covering box 2, a lid portion 3, an outer box 4, a box storage portion 10, a heated air supply portion 20, and an exhaust portion 30. In addition, a built-in box 50 arranged in the box storage portion 10 is provided. In the volume reduction/volume reduction processing device 1 of the present embodiment, the object to be processed is stored in the built-in box 50. If the built-in box 50 is placed in the box storage section 10, the heating air supply section 20 can be used. The supplied heated air heats and dries the object to be processed.

＜Cover box 2 and cover 3＞ As shown in Figure 1, the volume reduction/volume reduction processing device 1 of this embodiment is provided with a hollow covering box 2, and inside the covering box 2 is housed: a box storage section 10, a heated air supply section 20, and an exhaust Section 30 (introduction flow path 31 of exhaust section 30 and purification member storage section 32). In addition, a cover 3 that closes the top surface of the covering box 2 is provided. The cover 3 is swingably connected to the covering box 2 by a hinge or other connecting portion 2y, and by swinging the cover 3, the top surface of the covering box 2 can be closed and opened. That is, the lid 3 is swung, and the upper end of the covering box 2 is in contact with the inner surface of the lid 3 (the lid 3 is closed), and the inside of the covering box 2 is almost airtight from the outside. Sexually closed. In addition, in the inner surface of the cover 3, a gasket or the like may be provided in a portion contacting the upper end of the covering box 2 (especially a portion corresponding to the opening 10a of the box storage portion 10 described later). If a gasket is installed, the volume can be reduced during operation, and the leakage of odor can be prevented during stop. However, as will be described later, the inside of the covering box 2 becomes a negative pressure by discharging a part of the air to the outside. Therefore, in a state where the lid 3 is closed, even if a gasket or the like is not provided on the lid 3, it is possible to prevent the air in the covering box 2 from leaking to the outside.

In addition, the cover 3 is provided with a control unit 40 for controlling the operation of the device; on the top surface of the cover 3, a button for operating the volume reduction/volume reduction processing device 1 is provided. The control unit 40 controls the operation of the heated air supply unit 20 in accordance with the input from the button or the like.

In addition, the cover 3 may be provided with a display that displays the operation status of the volume reduction/volume reduction processing device 1 and the like.

In addition, the covering box 2 may be integrally formed, or may be formed by combining a plurality of members. For example, as shown in FIG. 7, three components such as the upper part 2-1, the middle part 2-2 and the lower part 2-3 may be combined to form the covering box 2.

In addition, when a plurality of members are combined to form the covering box 2, the airtightness may be lower than when the covering box 2 is integrally formed. That is, the airtightness of the connecting portion between each member may become low. However, the leakage of heated air can be reduced by arranging sealing members and the like in the connecting parts of the parts. In addition, if the covering box 2 is housed inside the outer box 4, etc., even if the airtightness of the covering box 2 is slightly reduced, the airtightness of the weight reduction/volume reduction processing device 1 itself does not occur, that is, Problems such as leakage of heated air.

In addition, when a plurality of members are combined to form the covering box 2, the shape of each member or the position where each member is divided are not particularly limited. For example, the upper part 2-1 and the middle part 2-2 may have a cylindrical shape with openings up and down, and the lower part 2-3 may be a bottomed cylindrical member. If each member is formed into such a shape, the leakage of heated air from the covering box 2 to the outside can be reduced. Naturally, the covering box 2 can also be formed by two members of a cylindrical upper part with upper and lower openings and a bottomed cylindrical lower part, or by three or more cylindrical parts with upper and lower openings , And a cylindrical part with a bottom to form a covered box 2.

＜External Box 4＞ As shown in FIGS. 1 and 2, the covering box 2 is housed in the outer box 4. Specifically, the outer box 4 is provided in such a way that the outer box 4 covers the side and bottom surfaces of the covering box 2 and the outer box 4 and the cover 3 can isolate the covering box 2 from the outside. The outer box 4 is formed into a size such that a gap 4h is formed between the outer box 2 and the covering box 2 in a state where the covering box 2 is housed inside. In addition, the outer box 4 is provided with an external suction port 4g that communicates the outside and the inside of the outer box 4 (refer to FIG. 8(B)). The external suction port 4g can be of any structure. For example, a gap or slit can be formed on the boundary between the covering box 2 and the external box 4, and the boundary between the cover 3 and the external box 4 to make it an external suction port. 4g. If the external suction port 4g is provided at the position of the connecting portion 2y that connects the covering box 2 and the lid portion 3, the boundary between the covering box 2 and the outer box 4, and the boundary between the lid portion 3 and the outer box 4 can be reduced.的 gap. In this way, the airtightness between the inside and outside of the gap 4h of the outer box 4 can be increased. In addition, the external air suction port 4g can be made inconspicuous, so the appearance of the weight reduction/volume reduction treatment device 1 can be refreshed.

In addition, a suction port 2g is formed in the covering box 2, which communicates the gap 4h between the inside of the covering box 2 and the outer box 4 with the lid 3 closed (refer to FIGS. 1 and 5). In addition, the cover 3 is provided with an exhaust flow path 33 of the exhaust 30 communicating between the inside and the outside of the covering box 2. That is, although the inside of the covering box 2 is hermetically sealed to some extent, it is possible to introduce outside air into the covering box 2 and to discharge a part of the heated air from the inside of the covering box 2.

In addition, if the outer box 4 is provided, it is possible to block the sound originating from the action of the heating air supply part 20 in the covering box 2 or the air flowing in the covering box 2, so that the reduction/reduction of the volume in this embodiment can be suppressed A situation where the operating sound of the processing device 1 leaks to the outside. That is, the volume reduction/volume reduction processing device 1 of this embodiment can be muted.

Although the shape and size of the outer box 4 are not particularly limited, the outer box 4 is preferably a seamless box without protrusions or the like inside. If it is a seamless box, the air in the gap 4h between the covering box 2 and the outer box 4 can flow smoothly, and thus the gap 4h originating from the covering box 2 and the outer box 4 can also be reduced. The noise of the moving air.

＜Box storage part 10＞ As shown in FIG. 1 and FIG. 5, in the covering box 2, a box storage portion 10 is provided. The box storage section 10 includes a storage space 10h in which the built-in box 50 is stored. This storage space 10h has an opening 10a at the upper part, and when the covering box 2 is closed by the cover 3, the opening 10a is airtightly isolated from the outside.

In addition, a supply port 10 c is formed in the cassette storage portion 10, and the supply port 10 c communicates with the air flow forming portion 21 of the heated air supply portion 20 via the supply flow path 22. The supply port 10c is provided at the bottom of the box storage portion 10. Specifically, in the center portion of the box storage portion 10, a recess 10d recessed from the bottom surface of the box storage portion 10 is provided. A supply port 10c is provided on the side surface of the recess 10d. That is, the heated air supplied from the heated air supply unit 20 enters the recessed portion 10d from the supply port 10c, and enters the storage space 10h from the recessed portion 10d.

On the other hand, a discharge surface 10f is provided on the inner surface of the upper portion of the cassette storage portion 10. The discharge surface 10f becomes an inclined surface that slopes downward toward the inner side of the storage space 10h, and a plurality of discharge ports 10k are formed on the discharge surface 10f (refer to FIG. 5). These plural discharge ports 10k are openings that communicate with the space 2h between the box accommodating portion 10 and the inner surface of the covering box 2. That is, the heated air entering from the supply port 10c into the storage space 10h of the cassette storage section 10 flows from the bottom to the upper side in the storage space 10h, and is discharged from the plurality of discharge ports 10k to the space 2h. That is, the heated air supply part 20 circulates the heated air between the storage space 10h and the space 2h.

In addition, it is preferable that the plurality of discharge ports 10k of the discharge surface 10f are formed so as to cover the entire circumference of the storage space 10h of the cassette storage section 10. In this way, the heated air that enters the storage space 10h from the recess 10d flows over the entire circumference of the storage space 10h, so it is easy to make the flow of the air in the storage space 10h uniform. In this case, the method of providing a plurality of discharge ports 10k on the discharge surface 10f is not particularly limited. For example, a plurality of discharge ports 10k having substantially the same shape may be provided on the entire discharge surface 10f (that is, the entire circumference of the cartridge storage portion 10) along the inner surface of the cartridge storage portion 10 at equal angular intervals. In addition, a plurality of discharge ports 10k of different shapes may be provided on the entire circumference of the cassette storage portion 10, and a plurality of discharge ports 10k of the same shape may be provided on the entire circumference of the cassette storage portion 10 at unequal intervals.

In addition, the discharge surface 10f having a plurality of discharge ports 10k may be formed so as not to cover the entire circumference of the storage space 10h. In this case, if a discharge surface 10f having a plurality of discharge ports 10k is formed in a certain range of the cassette storage portion 10, the flow of air can be uniformized to a certain degree.

In addition, the arrangement positions of the supply port 10c and the discharge port 10k do not have to be limited to the above-mentioned positions. What is necessary is just to arrange so that the heated air which entered into the storage space 10h of the cassette storage part 10 from the supply port 10c may flow upwards from the bottom in the storage space 10h. For example, the supply port 10c may be formed on the side surface near the bottom of the storage space 10h below the upper end of the built-in box 50. In addition, the recess 10d may not be provided on the bottom surface of the box storage section 10, and a through hole may be provided at the bottom of the storage space 10h as the supply port 10c. Further, the discharge port 10k is located on the side surface of the storage space 10h of the box storage portion 10, if it is a position where the storage space 10h can be communicated with the space 2h, and the built-in box 50 is placed in the storage space 10h, the supply At least most of the heated air passes through the position of the built-in box 50, and it can be set anywhere. That is, if all the heated air supplied from the supply port 10c to the storage space 10h does not take a shortcut from the supply port 10c to the discharge port 10k, it can be installed anywhere.

In addition, there is an advantage that if the plurality of discharge ports 10k of the discharge surface 10f are arranged at the positions as described above, the same effects as described above can be obtained. However, the exhaust port 10k is set to allow the heated air to pass through the processed object in the built-in box 50 when the built-in box 50 is arranged, and the heated air that has passed through the processed object can be discharged to the space for 2 hours. , The location of the discharge port 10k is not particularly limited. Naturally, the discharge surface 10f as described above may not be provided, but only as an opening connecting the storage space 10h and the space 2h, and the discharge port 10k may be formed on the side surface of the storage space 10h.

＜Heated air supply unit 20＞ As shown in FIGS. 1 and 5, the air flow forming part 21 of the heated air supply part 20 is provided in the lower part of the box storage part 10 in the covering box 2. As shown in FIG. The air flow forming portion 21 opens the air suction port in the space 2h of the covering box 2, and the discharge port communicates with the supply port 10c of the storage space 10h through the supply flow path 22. On the other hand, the air flow forming portion 21 is provided so that its discharge port faces the lateral direction (horizontal direction). That is, the airflow forming portion 21 is provided to discharge air in a direction crossing the direction in which the air flows in the storage space 10h.

As shown in FIG. 1 and FIG. 5, the supply flow path 22 is provided so that the supply port of the airflow formation part 21 may be connected with the supply port 10c provided in the recessed part 10d of the accommodation space 10h. Specifically, the supply channel 22 has a structure that is bent in a substantially U-shape when viewed from the side. More specifically, the supply flow path 22 is composed of the following elements: linear flow paths 22a, 22b separated by a partition wall 22d; and a reverse flow path 22c, one end of these linear flow paths 22a, 22b The parts (right end parts in FIGS. 1 and 5) are connected and have a substantially cylindrical inner surface. Among these linear flow paths 22a and 22b, the other end of the lower flow path 22a (the left end in FIGS. 1 and 5) communicates with the supply port of the air flow forming portion 21, and one end of the upper flow path 22b (The left end in FIGS. 1 and 5) communicates with the supply port 10c.

The supply flow path 22 is provided with a heating unit 25 that heats the air flowing in the supply flow path 22. The heating part 25 is, for example, a heater or the like provided in the lower flow path 22a, and by bringing air into contact with the heating part 25, the air can be heated to a predetermined temperature (for example, 90 degrees or more).

Therefore, if the airflow forming part 21 of the heated air supply part 20 is activated, the air in the covering box 2 can be heated to a predetermined temperature, and the heated air (heated air) can be supplied to the storage space 10h through the supply port 10c Inside.

In addition, the air in the storage space 10h (for example, heated air after contacting the object to be processed) is discharged from the discharge port 10k into the space 2h of the covering box 2. Therefore, if the airflow forming portion 21 is activated, the heated air can be circulated in the order of the space 2h covering the box 2, the heated air supply portion 20, the storage space 10h of the box storage portion 10, and the space 2h covering the box 2. In this way, the air is heated several times by the heating unit 25, so it is easy to maintain the temperature of the heated air supplied into the storage space 10h at a predetermined temperature or higher. In addition, the energy required for heating the air to a predetermined temperature by the heating unit 25 can also be reduced. In addition, even if the heating period by the heating unit 25, that is, the time during which the air is in contact with the heating unit 25 is shortened, it is easy to raise the heated air to a predetermined temperature. In this way, since the flow rate of the air flow formed by the air flow forming portion 21 can also be increased, the flow rate of the heated air in the storage space 10h of the box storage portion 10 is also increased, and the drying of the processed object can be increased. effectiveness.

In addition, although the heating air supply part 20 may supply all the air discharged from the air flow forming part 21 to the supply port 10c, it is desirable to discharge a part of the air to the introduction flow path 31 of the exhaust part 30. In this case, a part of the heated air is discharged from the exhaust part 30 to the outside, so the air pressure in the space 2h of the covering box 2 becomes lower, and new air is introduced from the gap 4h of the outer box 4 through the suction port 2g. To the space of the covering box 2 within 2h. That is, a certain amount of air (about 2-20% of the volume of the storage space 10h) can be circulated, and a certain amount of fresh air can be introduced into the storage space 10h. In this way, the humidity of the circulating air can be suppressed within a certain range (0-50% when the device is operating in a stable state), so the drying of the processed objects by heating air can be effectively performed . In addition, the state in which the operation of the device is stable refers to a state in which the device becomes a stable operation after a certain amount of time has passed from the start of the operation of the device.

In addition, the structure of the reversing flow path 22c is not particularly limited, and it is sufficient to allow air to flow smoothly from the lower flow path 22a to the upper flow path 22b. For example, if the inner bottom surface 22f of the reverse flow path 22c becomes a substantially cylindrical surface or a substantially spherical surface when viewed from the side, the air can flow smoothly from the lower flow path 22a to the upper flow path 22b (refer to the figure). 1 and Figure 5).

Furthermore, in the above-mentioned example, although the heating part 25 is provided in the lower flow path 22a, the heating part 25 may be provided in the upper flow path 22b. However, if the heating unit 25 is provided in the lower flow path 22a, it is easy to make the temperature of the air uniform between the air flowing from the heating unit 25 to the supply port 10c. In this way, the temperature of the heated air supplied into the storage space 10h can be made close to uniform, so the temperature of the air flowing in the storage space 10h can be made close to uniform. In addition, the heating part 25 is located on the upstream side of the reversing flow path 22c, so even if water or the like enters the supply flow path 22, the possibility of water contacting the heating part 25 can be reduced. In this way, damage to the heating part 25 caused by contact with moisture can be prevented, and the service life of the device can be prolonged.

In order to make the temperature of the heated air nearly uniform, it is preferable that the inner bottom surface 22f of the reversing flow path 22c adopts a structure that disturbs the flow of the air. For example, as the inner bottom surface 22f of the reversing flow path 22c, a shape that also generates flow in a direction (horizontal direction) intersecting the direction from the lower flow path 22a to the upper flow path 22b may be adopted. For example, it is possible to adopt a method of providing two reversing surfaces on the inner bottom surface 22f of the reversing flow path 22c, or providing a plurality of cylindrical surfaces whose axial directions are along the vertical direction.

In addition, the airflow forming part 21 is, for example, a multi-blade fan, an axial flow propeller fan, etc., but it is not particularly limited. However, if the air suction port and the discharge port are perpendicular to each other like a multi-blade fan, the advantage is that even if the discharge port of the airflow forming portion 21 is arranged as described above, the length in the vertical direction of the device can be shortened.

Furthermore, the airflow forming part 21 may be arranged so that the direction in which the air is discharged from the discharge port becomes the same direction as the direction in which the air flows in the storage space 10h. In this case, it is preferable to arrange so that the discharge port of the airflow formation part 21 may become a position shifted below the center of the storage space 10h. In this way, the supply flow path 22 connecting the discharge port of the airflow forming part 21 and the supply port 10c is easily brought into a meandering state, etc. Therefore, advantages such as preventing moisture from flowing into the airflow forming part 21 and reducing pressure loss can be obtained.

＜Exhaust part 30＞ As shown in FIGS. 1 and 5, a part of the air discharged from the discharge port of the airflow forming part 21 becomes the introduction flow path 31 of the branch port 22v flowing into the exhaust part 30 from the branch port 22v of the supply flow path 22, and the branch port 22v is provided Between the discharge port of the airflow forming part 21 and the position where the heating part 25 is provided.

The exhaust section 30 includes an introduction flow path 31, a purification member storage section 32, and an exhaust flow path 33. That is, when the air discharged from the airflow forming portion 21 flows into the introduction flow path 31, the air flows into the purification member storage portion 32 through the introduction flow path 31. Then, the air that has flowed into the purification member storage portion 32 is purified by the purification member 35 in the purification member storage portion 32 and then discharged to the outside through the exhaust flow path 33. In addition, the arrangement and shape of the introduction flow path 31, the purification member storage portion 32, and the exhaust flow path 33 of the exhaust portion 30 are not particularly limited, and for example, the following arrangements and shapes may be used.

＜Purification component storage section 32＞ First, the purification member accommodating portion 32 stores the purification member 35 that purifies the air. The purification member storage portion 32 is provided in the side space of the box storage portion 10 in the covering box 2. The purification member 35 is accommodated in the purification member accommodating portion 32, and the air discharged to the outside is discharged to the outside after passing through the purification member 35. In this way, when the object to be processed is processed by the device, it is possible to prevent the air discharged from the device from deteriorating the environment around the device. In addition, as the purification member 35, for example, a conventional deodorant, a filter that removes harmful components contained in the air, activated carbon, etc. can be used.

＜Introduction flow path 31＞ As shown in FIGS. 1 and 5, an introduction flow path 31 is provided between the aforementioned purification member storage portion 32 and the branch port 22v of the supply flow path 22. The introduction flow path 31 communicates between the purification member storage section 32 and the supply flow path 22, and only a part of the heated air flowing in the supply flow path 22 can be supplied to the purification member storage section 32, and there is no arrangement or the like. Specially limited. For example, the introduction flow path 31 may be formed as follows.

The introduction flow path 31 includes a bottom flow path 31a communicating with the branch port 22v. The bottom flow path 31a is provided below the lower flow path 22a along the lower flow path 22a to below the reverse flow path 22c.

As shown in FIGS. 2 and 6, the bottom flow path 31a is connected to the lower ends of a pair of lead direct current paths 31b and 31b extending upward under the reverse flow path 22c. The pair of lead direct current paths 31b and 31b are arranged to sandwich the reversing flow path 22c on both sides of the reversing flow path 22c.

Between the pair of lead direct current paths 31b and 31b and the purification member accommodating portion 32, a deceleration portion 31c is provided. The decelerating portion 31c is provided to decelerate the flow velocity of the air flowing from the pair of lead direct current paths 31b, 31b, and has a labyrinth structure, for example. Specifically, as shown in FIG. 6, the deceleration unit 31c includes an upper space as, a lower space bs, and a side flow path ss; and the lower space bs communicates with a pair of lead direct current paths 31b and 31b. The lower space bs and the upper space as are separated by the partition wall ds; the lower space bs and the upper space as are connected by the lateral flow path ss provided on the side of the upper space as. With this structure, the air flowing from the pair of lead direct current paths 31b and 31b into the lower space bs does not directly flow into the upper space as. That is, the air flowing upward from the pair of lead direct current paths 31b and 31b into the lower space bs is first converted into a horizontal flow, then becomes an upward flow again and flows into the purification member storage portion 32. In addition, it is a structure in which the direction in which the air flows from the lower space bs to the side flow path ss, and the direction in which the air flows from the side flow path ss to the upper space as intersect. With such a structure, the flow velocity of the air flowing into the purification member storage portion 32 can be reduced.

＜Exhaust flow path 33＞ As shown in FIGS. 1, 2, and 4, the cover 3 is provided with an exhaust flow path 33 for discharging the air flowing out of the purification member accommodating portion 32 to the outside. The exhaust flow path 33 is a flow path that communicates between the inlet 33a and the exhaust port 33b, and the inlet 33a is provided at a position opposed to the purifying member accommodating portion 32 when the lid portion 3 is closed. The opening 33b is provided on the top surface of the cover 3. For example, the introduction port 33a is provided in two places on the inner surface of the cover 3 (refer to FIG. 4(B)). In addition, as shown in FIG. 8, the exhaust port 33 b is provided on the outer surface of the cover 3 along the outer circumference of the cover 3. In addition, the structure of the exhaust flow path 33 in the cover 3 is not particularly limited. In addition, the installation number of the introduction port 33a, the installation position or shape of the exhaust port 33b, etc. are also not particularly limited.

＜Resistance member 33c＞

In addition, in the state where the lid 3 is closed, a resistance member 33c is provided between the inner surface of the lid 3 and the top surface of the purification member storage portion 32 (refer to FIGS. 2 and 4(A)). The resistance member 33c is formed at a position corresponding to the introduction port 33a of the cover 3 so as to increase the flow resistance of the air passing through the resistance member 33c. In this way, the flow of air passing through the purification member 35 in the purification member storage portion 32 can be made nearly uniform.

The method of changing the flow resistance in the resistance member 33c is not particularly limited. For example, when the resistance member 33c is formed into a slit shape as shown in FIG. 4, the position corresponding to the introduction port 33a (that is, the portion where the resistance increases) may be inclined with respect to the slit in the vertical direction. (In other words, the inclination with respect to the direction perpendicular to the inner surface of the cover 3) is larger than other parts.

The volume reduction/volume reduction processing device 1 of this embodiment has the same configuration as described above. Therefore, if the heated air supply unit 20 is activated, the storage space 10h of the cartridge storage unit 10 can be formed from the bottom of the storage space 10h upward. The flow of heated air. In this way, if the built-in box 50 whose bottom has air permeability is arranged in the storage space 10h, the heated air can also flow from the bottom to the upper opening in the built-in box 50. Since the heated air flows from the bottom of the built-in box 50, even if the drying and volume reduction of the processed object in the built-in box 50 progress, the heated air is in contact with the processed object, specifically, the processed object The distance from the supply port 10c remains unchanged, so the drying efficiency for drying the processed object can be improved.

In addition, the heated air circulates between the space 2h of the covering box 2 and the storage space 10h of the box storage portion 10, so the energy required for heating of the air can be reduced.

In addition, a part of the heated air circulating between the space 2h of the covering box 2 and the storage space 10h of the box storage section 10 is exhausted to the outside by the exhaust section 30. On the other hand, the external air introduced from the external air intake port 4g into the external box 4 is introduced into the space 2h of the covering box 2 through the air intake port 2g. In this way, the heated air can be circulated, and a part of the air that comes into contact with the object to be processed and becomes high in humidity is replaced with low humidity outside air. Therefore, the humidity of the heated air can be maintained within a certain range, so the drying efficiency can be improved.

＜Built-in box 50＞ The built-in box 50 is housed in the storage space 10h of the box storage section 10 in a state in which to-be-processed objects such as water-containing garbage are placed. In a manner of maintaining the storage in this built-in box 50, the object to be processed is brought into contact with heated air, and the volume is reduced and dried.

As shown in Figs. 9 and 10, the built-in box 50 has an air-permeable structure at the bottom, and heated air is supplied to the inside from the bottom. If the built-in box 50 has an air-permeable structure at the bottom, it can be used in the volume reduction/volume reduction processing device 1 of this embodiment. However, if it has the following structure, it can suppress that the moisture of the to-be-processed object leaks from the bottom surface of the built-in box 50. In this way, the following advantages are obtained; the water droplets can be prevented from flowing into the airflow forming portion 21, and the storage space 10h can be prevented from being stained by the moisture of the object to be processed.

In addition, the "preventable leakage of moisture from the processed object in the built-in box 50 from the bottom surface of the built-in box 50" mentioned here also includes the case where the water does not leak at all, and the case where only a small amount of water still leaks. . A small amount of water leakage refers to the degree of dripping dripping into the storage space within 10 hours.

<An example of the built-in box 50> As shown in FIGS. 9 and 10, the built-in box 50 is composed of a main box 51 and a liquid receiving tray 52.

＜Main body box 51＞ The main body box 51 is a bottomed cylindrical member with an opening 51a at the upper end, and its cross-sectional shape is formed into a slightly oblong shape. The main body box 51 is formed such that the bottom 51b has air permeability. For example, as shown in FIGS. 9 and 10, a slit 51s and a through hole 51g are formed in the bottom part 51b, and the storage space 51h of the main body case 51 and the outside are ventilated through the slit 51s and the through hole 51g. That is, the heated air passes through the slit 51 s and the through hole 51 g, and enters the storage space 51 h of the main body box 51.

In addition, the bottom portion 51b of the main body box 51 forms a low-permeability area A with low liquid permeability at the center; around the low-permeability area A, a high-permeability area with a lower liquid permeability and a higher permeable area A is formed B. Specifically, the low liquid-passage region A is formed as a narrow slit 51s (for example, about 0.5 to 2 mm in width) extending from the center toward the periphery. In other words, the low-fluid-permeation area A is formed in such a manner that the center portion of the main body box 51 has the highest position and is inclined from the position toward the periphery. That is, the low-fluid-permeation area A becomes an inclined surface that slopes downward from the center portion toward the peripheral portion. Therefore, when the liquid drops to the low-pass-liquid area A, the liquid becomes easier to flow along the surface of the low-pass-liquid area A and along the axial direction of the slit 51s, rather than passing through the slit 51s.

In addition, the angle of the inclined surface of the low-fluid-permeation region A is not particularly limited, and it may be formed to an angle that allows the liquid to easily flow in the axial direction of the slit 51s.

In the above description, the case where the low-pass liquid area A is an inclined surface that slopes downward from the central part of the main body box 51 toward the peripheral part is described. However, the low-pass liquid area A may be formed more than the central part of the main body box 51. The position offset to either side has the highest position. Furthermore, the low-pass liquid area A does not have to be an inclined surface, and may be a surface (flat surface) that is not inclined to the horizontal.

＜Liquid receiving tray 52＞ As shown in FIGS. 9 and 10, the liquid receiving tray 52 is installed so as to cover the outer surface of the bottom 51 b of the main box 51. The liquid receiving tray 52 has an opening 52a into which the bottom 51b of the main body box 51 is inserted, and a vent 52h is provided at the center of the bottom 52b. The vent portion 52h is a through hole that penetrates the bottom portion 52b of the liquid receiving tray 52, and has an upright wall-shaped portion around it. In addition, between the wall-shaped portion erected around the vent portion 52h and the edge portion of the liquid receiving tray 52, a liquid storage portion 52g capable of storing liquid is provided.

The vent portion 52h is formed to be located below the low liquid-permeable area A when the liquid receiving tray 52 is mounted on the bottom 51b of the main body box 51. In addition, the vent portion 52h is formed so that the area in a plan view is smaller than the area of the low liquid-permeation region A in a plan view. That is, when the main body box 51 is viewed from above with the liquid receiving tray 52 mounted on the bottom 51b of the main body box 51, the entire vent 52h is hidden by the low-permeation liquid area A. The receiving tray 52 forms a vent 52h.

In addition, the liquid receiving tray 52 is formed in a shape in which when the built-in cassette 50 is placed in the storage space 10h of the cassette storage portion 10, the vent portion 52h is arranged above the recessed portion 10d. For example, the liquid receiving tray 52 is formed into a shape slightly similar to the cross-sectional shape of the storage space 10h in plan view.

In addition, the liquid receiving tray 52 is formed such that if the built-in box 50 is placed in the storage space 10h of the box storage portion 10 with the liquid receiving tray 52 mounted on the bottom 51b of the main box 51, the bottom 52b will be outside. The surface is in close contact with the inner bottom surface of the storage space 10h (refer to Figure 1 and Figure 5).

If the built-in box 50 has the structure as described above, if the built-in box 50 is arranged in the storage space 10h, the vent 52h of the liquid receiving tray 52 can be stably arranged above the recess 10d. In this way, most of the heated air supplied from the heated air supply portion 20 to the recessed portion 10d can be reliably supplied to the bottom 51b of the main body box 51 through the vent portion 52h of the liquid receiving tray 52.

In addition, the low liquid-permeable area A of the bottom 51b of the main body box 51 is located above the vent 52h, so it is possible to minimize the water droplets that pass through the vent 52h and drop onto the recess 10d.

In addition, when the built-in box 50 is arranged in the storage space 10h, if the vent 52h is arranged above the recess 10d, the liquid receiving tray 52 does not have to have a shape similar to the cross-sectional shape of the storage space 10h. For example, a positioning protrusion or the like may be provided on the outer surface of the liquid receiving tray 52 (or the outer surface of the main box 51 or in the storage space 10h), and positioning by the protrusion or the like allows the vent to be arranged above the recess 10d 52h. In the case of positioning in this way, the vent portion 52h of the liquid receiving tray 52 may be stably arranged above the recessed portion 10d.

＜Other structures of the built-in box 50＞ In the above-mentioned built-in box 50, a space (a space serving as the liquid storage portion 52g) is formed between the bottom 51b of the main body box 51 and the top surface of the liquid receiving tray 52. Through this space, heated air is supplied to a portion of the high-fluid-permeation area B or the low-fluid-permeation area A that is not located above the ventilation portion 52h. This space may be a whole space as a whole, or it may be divided into a plurality of ventilation spaces as described below. If it is divided into a plurality of ventilation spaces, the heated air supplied to each part in the storage space 51h of the main body box 51 through each ventilation space can be adjusted to an appropriate flow rate.

For example, when the object to be processed is offset and stored in the storage space 51h of the main body box 51, a large amount of heated air becomes easy to flow to a small part of the object to be processed. However, if the space between the bottom 51b of the main body box 51 and the top surface of the liquid receiving tray 52 is separated into a plurality of ventilation spaces, the area communicating with each ventilation space in the storage space 51h of the main body box 51 can be Supply almost the same amount of heated air.

As shown in FIGS. 11-13, a separation wall 51w is provided on the bottom 51b of the main body box 51. As shown in FIG. The separation wall 51w includes a vertical separation wall 51w1 extending in the longitudinal direction of the main body box 51. The vertical separation wall 51w1 is provided to divide the low-fluid-permeation area A and the high-fluid-permeation area B into two in the width direction (the vertical direction in FIG. 12). In addition, the plurality of separation walls 51w have horizontal separation walls 51w2 extending in the short axis direction (left-right direction) of the main body box 51. This horizontal separation wall 51w2 is provided so that the low liquid-permeation area A and the high liquid-permeation area B are divided into two in the left-right direction (the left-right direction in FIG. 12) by the vertical separation wall 51w1. Further, the plurality of separation walls 51w includes an oblique separation wall 51w3 that divides the low-permeation area A and the high-permeation area B into two each divided into four by the vertical separation wall 51w1 and the lateral separation wall 51w2. That is, a plurality of separation walls 51w1 to 51w3 of the separation wall 51w are provided to divide the low-pass liquid area A and the high-pass liquid area B into eight.

And the plurality of separation walls 51w1 to 51w3 of the separation wall 51w, in the state where the main body box 51 is mounted on the liquid receiving tray 52, the lower end thereof is formed to a length which is in contact with the top surface of the liquid receiving tray 52 (or a small gap is formed). Degree of length). That is, it is set so that the distance from the top surface of the liquid receiving tray 52 to the bottom surface of the bottom 51b of the main body box 51 in the corresponding position is almost the same length as the height of the separation wall 51w (refer to FIG. 11(B)) , Figure 13(A)). In addition, at positions corresponding to the vent 52h of the liquid receiving tray 52, a plurality of separation walls 51w1 to 51w3 of the separation wall 51w are arranged from the upper end of the vent 52h of the liquid receiving tray 52 to the bottom of the main box 51 The distance L from the highest position of the bottom surface of 51b is about half of the distance L (refer to Fig. 11(B) and Fig. 13(A)).

Due to this structure of the present invention, if the main body box 51 is mounted on the liquid receiving tray 52, a plurality of ventilation spaces are formed between the bottom 51b of the main body box 51 and the top surface of the liquid receiving tray 52. In addition, the plurality of separation walls 51w1 to 51w3 of the separation wall 51w are set to the position of the low liquid-permeation area A, so when viewed from the bottom of the inner box 50, a part of all the air-permeable spaces overlaps with the air-permeable portion 52h of the liquid receiving tray 52 (Refer to Figure 12(B)).

In this way, in the ventilation space, heated air is supplied to each ventilation space from the part overlapping with the ventilation part 52h. In addition, the areas of the low liquid-permeable area A and the high liquid-permeable area B that communicate with each vent space become almost the same area, so the amount of heated air supplied from each vent space to the inside of the storage space 51h of the main body box 51 becomes how much Nearly the same. That is, in the storage space 51h of the main box 51, heated air can be supplied in a nearly uniform state (almost the same flow rate), and uneven drying of the processed object can be prevented.

In addition, at a position corresponding to the vent portion 52h of the liquid receiving tray 52, the separation wall 51w is longer than the distance L from the upper end of the vent portion 52h of the liquid receiving tray 52 to the highest position of the bottom surface of the bottom 51b of the body box 51 It may be shorter, and it does not have to be about half the distance L. However, as described above, at a position corresponding to the vent 52h of the liquid receiving tray 52, if the height of the plurality of separation walls 51w1 to 51w3 of the separation wall 51w becomes a height of about half of the distance L, it is easy to pass the liquid receiving tray The heated air of the ventilation part 52h of 52 is supplied to each ventilation space in a nearly uniform state.

On the other hand, the amount of heated air that flows into the storage space 51h of the main body box 51 through the high-flow liquid region B becomes larger than that of the low liquid-permeation region A. Therefore, the amount of air supplied from each ventilation space to the main body box 51 is increased. As the amount of heated air inside the storage space 51h becomes nearly equal, it is preferable to adjust the opening area that communicates the storage space 51h of the main body box 51 with each ventilation space in the high-permeability area B. For example, in a state where the heated air is supplied from the heated air supply portion 20 through the vent portion 52h of the liquid receiving tray 52, adjustment is made so that the pressure in each ventilating space becomes the same pressure, so that the vent portion 52h passes through each ventilating space. The amount of heated air supplied from each ventilation space to the inside of the storage space 51h of the main body box 51 may be approximately equal. For example, with respect to the width of the storage space 51h of the main body box 51 (in the vertical direction in FIG. 12), if the ratio of the opening portion of the high-permeable liquid area B is about 10 to 40%, it is possible to supply air from each ventilation space to the main body box. The amount of heated air inside the storage space 51h of 51 becomes a nearly uniform state.

In addition, the "pressure in each ventilation space is the same pressure" mentioned here is not limited to the case where the pressure is exactly the same, but also includes the case where there is a certain degree of pressure difference. In addition, "a state where the amount of heated air supplied from each ventilation space to the inside of the storage space 51h of the main body box 51 is approximately equal" also includes a case where the flow rate has a certain degree of difference.

For example, the object to be processed in the storage space 51h of the main box 51 is unevenly distributed. Even if it is close to "the pressure in each venting space is the same pressure", the heated air will not easily pass through the area where there are many objects to be processed. The heated air passes through the area with few objects to be processed. However, if the ratio of the opening portion of the high-pass liquid area B is adjusted, even if there is an uneven distribution of the objects to be processed, it is easy to reduce the flow rate difference between an area with a large amount of objects to be treated and an area with a small amount of objects to be treated. That is, even if there is uneven distribution of the processed objects, it is easy to perform drying effectively. As in this state, the state in which the heated air flows from each vent space to the various parts in the storage space 51h of the main body box 51 is also included in the heating that is "supplied from each vent space to the inside of the storage space 51h of the main body box 51 The amount of air becomes nearly equal."

In addition, the separation wall 51w is set so that when viewed from the bottom of the inner box 50, a part of all the ventilation spaces overlaps with the ventilation portion 52h of the liquid receiving tray 52, and the low liquid flow area A and the high liquid flow area connected by each ventilation space The area of the area B does not have to be almost the same area. That is, the areas of the low-pass liquid area A and the high-pass liquid area B may be different depending on the ventilation spaces. In this way, the flow of the heated air in the storage space 51h of the built-in box 50 can be adjusted.

The discharge surface 10f (ie, a plurality of discharge ports 10k) that discharges heated air from the storage space 10h of the cartridge storage portion 10 is not formed in a partial offset over the entire circumference of the storage space 10h of the cartridge storage portion 10, If it is formed so that the areas of the low-permeation area A and the high-permeation area B that communicate with the ventilation spaces are almost the same area, the flow of the heated air flowing inside the storage space 51h of the built-in box 50 is The possibility of unevenness. As a result, the contact state between the heated air and the processed object is also uneven, and the drying of the processed object may not be performed properly. Therefore, as in the above case, it is also possible to adjust the flow of the heated air flowing inside the storage space 51h so that the contact state between the heated air and the object to be processed becomes an appropriate state. For example, it is also possible to provide a ventilation space communicating with the area where the heated air easily flows inside the storage space 51h, so that the area of the low liquid-permeable area A and the high liquid-permeable area B is smaller than that of the heated air in the storage space 51h. The areas of the low liquid-permeable area A and the high liquid-permeable area B in the ventilation space connected by the areas are smaller. Specifically, if the areas of the low-permeation area A and the high-permeation area B are reduced in the ventilation space close to the discharge surface 10f, the areas of the low-permeation area A and the high-permeation area B are reduced in the ventilation space away from the discharge surface 10f. If it increases, the contact state between the heated air and the object to be processed is likely to be in an appropriate state.

In addition, even in the case where the supply port 10c is offset from the center of the cartridge storage section 10, when the areas of the low-permeation area A and the high-permeation area B that communicate with the respective ventilation spaces are formed to be almost the same area, There is a possibility that the flow of the heated air flowing inside the storage space 51h is uneven and the object to be processed cannot be dried properly. In this case, the flow of the heated air flowing inside the storage space 51h may also be adjusted so that the contact state of the heated air and the object to be processed becomes an appropriate state. For example, it is also possible to provide a ventilation space communicating with the area where the heated air easily flows inside the storage space 51h, so that the area of the low liquid-permeable area A and the high liquid-permeable area B is smaller than that of the heated air in the storage space 51h. The areas of the low liquid-permeable area A and the high liquid-permeable area B in the ventilation space connected by the areas are smaller. Specifically, if the areas of the low-permeation area A and the high-permeation area B are reduced in the ventilation space close to the supply port 10c, the areas of the low-permeation area A and the high-permeation area B are reduced in the ventilation space far from the supply port 10c. If it increases, the contact state between the heated air and the object to be processed is likely to be in an appropriate state.

The state of "heated air passing through each ventilation space at an appropriate flow rate" stated in claim 9 that falls within the scope of the invention application includes not only "the amount of heated air supplied from each ventilation space to the inside of the storage space 51h of the main body box 51" The same (nearly equal state)" state also includes the "contact between the heated air and the object to be processed" even if the heated air supplied from each ventilation space to the inside of the storage space 51h of the main box 51 is uneven. The status is the appropriate status".

In addition, instead of providing a separation wall at the bottom 51b of the main box 51, or instead of providing a separation wall at the bottom 51b of the main box 51, a separation wall may be provided on the top surface of the liquid receiving tray 52. For example, when a separation wall is provided only on the top surface of the liquid receiving tray 52, if a slit-shaped separation wall is also provided in the vent portion 52h, the low liquid-permeation area A located above the vent portion 52h can also be divided.

In addition, when the object to be processed fills up the storage space 51h of the main body box 51, a large amount of heated air becomes easy to flow along the inner wall surface of the main body box 51. Therefore, if the flow of the heated air flowing into the storage space 51h of the main body box 51 is disturbed, the heated air can also be effectively brought into contact with the object to be processed inside the storage space 51h of the main body box 51. That is, the contact efficiency between the object to be processed and the heated air in the storage space 51h of the main body box 51 can be increased.

For example, as described above, in the liquid receiving tray 52, the air vent 52h is provided at the opening at the center of the liquid receiving tray 52; at the center of the bottom 51b of the main box 51, a low-fluid area A is formed; in the low-fluid area Around A, a high-throughput area B is formed (refer to Figure 12(A)). In this case, if the openings in the high-permeation liquid region B that communicate with the ventilation spaces in the main body box 51 are shaped as follows, the flow of the heated air flowing into the main body box 51 is likely to be disturbed.

As shown in FIG. 12(A), in the high-throughput region B, a plurality of arc-shaped through holes are formed. Specifically, there are provided: an inner through hole 51f located on the central portion side of the main body box 51; and an outer through hole 51i located on the outer side of the main body box 51 than the inner through hole 51f. The inner through hole 51f is formed in a convex arc shape on the central portion side (inside) of the main body box 51, and the outer through hole 51i is formed in a convex arc shape on the wall side (outside) of the main body box 51.

If the inner through-hole 51f and the outer through-hole 51i of these shapes are formed, compared with the case where a linear through-hole is provided, when passing through the through-holes 51f and 51i, it is easier to make the heated air flowing into the main body box 51 The flow is disturbed.

In addition, if only the flow of heated air flowing into the storage space 51h of the main body box 51 is disturbed, only the inner through hole 51f or the outer through hole 51i may be provided, or the inner through hole 51f and the outer through hole 51i may have the same shape It is not necessary to form the inner through-hole 51f and the outer through-hole 51i in an arc shape. However, the heated air flowing into the main body box 51 has the property of being easy to flow along the wall surface. Therefore, when the heated air flows into the main body box 51, it is preferable to form a flow from the wall surface side of the main body box 51 toward the inside. In forming such a flow of heated air from the wall surface side of the main body box 51 toward the inside, it is preferable to provide both the inner through hole 51f and the outer through hole 51i of the above-mentioned shape.

In addition, the volume of the processed object decreases as the drying progresses, but the heated air that flows into the storage space 51h of the main box 51 as the volume decreases becomes easier to flow along the wall surface. That is, the volume-reduced object to be processed becomes unevenly distributed in the center of the storage space 51h, and the heated air easily passes through the space between the object to be processed and the wall surface of the storage space 51h. To prevent these phenomena, it is preferable to increase the area of the inner through hole 51f more than the area of the outer through hole 51i. In this way, even if the volume of the processed object is reduced, it is easy to supply heated air to the inside of the processed object through the inner through hole 51f. In addition, by making the area of the inner through hole 51f larger than the area of the outer through hole 51i, it is easy to supply heated air to the inside of the object even in the initial stage of drying.

In addition, the inner through-hole 51f and the outer through-hole 51i may be formed so that a plurality of separation walls 51w1 to 51w3 sandwiching the separation wall 51w may be formed into a symmetrical shape. In this case, the difference in the flow of the heated gas flowing from the adjacent ventilation space into the storage space 51h of the main body box 51 can be reduced. Therefore, regardless of the state of the object to be processed in the main body box 51, it is easy to prevent dryness. all.

In the above example (FIGS. 9 to 13 ), an example of the built-in box 50 used when the heated air is supplied from the inner bottom surface (recess 10 d) of the storage space 10 h is shown. On the other hand, when the supply port 10c for supplying heated air to the storage space 10h is provided on the inner surface of the storage space 10h, etc., a leg is provided on the outer surface (bottom surface) of the bottom 52b of the liquid receiving tray 52. A gap is formed between the outer surface of the bottom portion 52b and the inner bottom surface of the storage space 10h. In this way, the heated air supplied from the supply port 10c can be supplied into the main body case 51 from the bottom part 51b of the main body case 51 through the vent 52h of the liquid receiving tray 52.

In addition, in the main body box 51, the installation locations of the low-permeation area A and the high-permeation area B are not necessarily limited to the above-mentioned locations. For example, the bottom portion 51b of the main body box 51 may be configured such that a part of the area in the high-fluid-permeation area B becomes the low-fluid-permeation area A.

Furthermore, it is not necessary to provide the low-permeation area A and the high-permeation area B on the bottom 51b of the main body box 51, and the entire bottom 51b can be formed only with the low-permeation area A. In this case, the moisture can be made more difficult to leak. .

Furthermore, the built-in box 50 may not be provided with the liquid receiving tray 52, and only constituted by the main box 51. In this case, it is not necessary to provide the low-permeation area A and the high-permeation area B at the bottom 51b of the main body box 51, and the entire bottom 51b can be used as the low-permeation area A to prevent moisture from leaking.

<Regarding the control of the heated air supply unit 20> As described above, the volume reduction/volume reduction processing device 1 of the present embodiment includes the control unit 40 that controls the operation of the device. The control unit 40 has, for example, a function of controlling the operation of the heated air supply unit 20 in accordance with ON (conduction)-OFF (disconnection) of the power supply. In addition, in the case of a timer input, the control unit 40 has the following functions: activate the heated air supply unit 20 for a predetermined time, activate the heated air supply unit 20 from a predetermined time to start the drying process of the to-be-processed object, and the like.

In particular, the control unit 40 preferably has a function of stopping the operation of the device, that is, stopping the operation of the heating air supply unit 20 (that is, the heating control unit) when the dry state of the processed object becomes a predetermined state. The method for the heating control unit to determine the dry state of the object to be processed is not particularly limited. For example, a sensor in contact with the processed object can also be installed to directly determine the dry state of the processed object. In addition, it is also possible to measure the humidity and/or temperature of the air in the storage space 10h of the box storage section 10, or the humidity and/or temperature of the heated air flowing in the supply flow path 22, and determine the value of the object to be processed from the measured value. Dry state.

Furthermore, by the heating control unit, the operation of the heating unit 25 of the heated air supply unit 20 is controlled ON-OFF to maintain the heated air at a predetermined temperature and dry the object to be processed, and it is also possible to determine the status of the object to be processed. The temperature of the processed object is not directly measured in the dry state. For example, if a thermocouple or the like is first installed on the upstream side of the air flow forming part 21 (that is, in the covering box 2), the heating control part turns ON-OFF the operation of the heating part 25 according to the temperature of the air. For example, if the temperature of the air exceeds a certain temperature, the heating control section turns off the heating section 25, and if the temperature of the air falls below a certain temperature, the heating control section turns on the heating section 25. In this case, if the ON-OFF period of the heating unit 25 is grasped, the temperature of the processed object (that is, the dry state) can be roughly grasped without directly measuring the temperature of the processed object. That is, it becomes unnecessary to install a special sensor for measuring temperature, so the structure of the device can be simplified.

The reason for grasping the dry state only by the ON-OFF cycle of the heating unit 25 is based on the following reasons. First, when the processed object contains moisture, the heat of the air is taken in order to evaporate the moisture. That is, since the heat of vaporization is supplied to the processed object, the temperature of the air returning from the storage space 10h is lowered, and the ON time becomes longer. That is, the ON-OFF cycle of the heating unit 25 becomes longer. On the other hand, as the drying of the object to be processed progresses, the heat of vaporization supplied to the object is reduced, so the temperature of the air returning from the storage space 10h decreases less. Therefore, the ON-OFF cycle of the heating unit 25 becomes shorter. In the case of incomplete drying of the processed object, there will be a difference in the ON-OFF cycle. However, if the processed object is dried more than a certain amount, it becomes unnecessary to supply the heat of vaporization, so the ON-OFF cycle becomes almost constant. Therefore, the ON-OFF cycle of the heating unit 25 is shortened, and when the ON-OFF is performed at a nearly constant cycle, the operation of the device is stopped. In this way, the operation of the device can be stopped in a state where the object to be processed is properly dried, and the device does not perform any operation other than necessary. Therefore, electricity costs can be saved, and energy can be saved.

The heating control unit of the control unit 40 may, for example, be a bimetal thermostat or a humidity sensor. Naturally, it is not limited to these forms.

In addition, the heating control unit can also have the function of controlling the operation of the heating unit 25 and the operation of the air flow forming unit 21 via the control unit 40, so as to determine the dry object and its state based on the ON-OFF cycle. It is suitable for the heating state of the processed object and its state for drying. For example, set the following function in the heating control unit: confirm the ON-OFF cycle of a certain period (initial heating) after the treatment of the object is started by the reduction/volume reduction processing device 1, and judge according to the ON-OFF cycle of the initial heating Dry processed objects and their state, etc. In this way, after a certain period of time has elapsed from the start of the treatment of the object to be treated, the object to be treated can be treated in a state suitable for the object to be treated. Therefore, the processing speed of the object to be processed can be increased, and the energy consumption required for processing can be suppressed.

In addition, the method for the heating control unit to determine the dried object and its state is not particularly limited. For example, change the type of the processed object and/or the state of the processed object (moisture content, etc.), and perform a pre-test to measure the ON-OFF cycle at the beginning of heating, and create a representation of the type of processed object and/or the state of the processed object The data of the relationship between (moisture content, etc.) and the ON-OFF cycle in the initial stage of heating (hereinafter referred to as the processing object discrimination map), the processing object discrimination map is first stored in the heating control unit. In this way, the heating control unit can determine the type of the processed object from the processed object discrimination chart based on the measured ON-OFF cycle. In addition, if a plurality of drying programs suitable for the type of the processed object are stored in the heating control unit in advance, the heating control unit can select an appropriate drying program according to the type of the processed object, etc., and implement it according to the type of the processed object, etc. Corresponding appropriate drying treatment.

In addition, when a plurality of heating units 25 are provided, if the heating control unit appropriately controls the operation of the plurality of heating units 25, the gas can be appropriately heated in accordance with the type, amount, and heating state of the object to be processed. For example, in the initial stage of drying, by activating a plurality of heating parts 25, the gas can be quickly heated to a predetermined temperature. In this way, the time until the heating of the object to be processed starts is shortened, so the processing time of the object to be processed can be shortened. In addition, when the temperature of the gas rises to a certain level, a part of the plurality of heating units 25 is operated. In this way, the temperature of the gas can be maintained at a predetermined temperature, and the power consumption of the heating unit 25 can be reduced. In addition, if the operations of a plurality of heating parts 25 are combined, the temperature adjustment of the gas becomes easy to perform. However, if a plurality of heating units 25 are operated alternately, etc., the operation time of each heating unit 25 can be shortened. In this way, the service life of each heating part 25 can be prolonged, and the service life of the device can also be prolonged. In addition, when a plurality of heaters and other heating units 25 are provided, all the same heaters may be used for the heaters used, or heaters with different power consumption and different sizes may be used. For example, the heating unit 25 to be used may be changed according to the position where the heating unit 25 is provided in the supply flow path 22.

When a plurality of heating units 25 are provided, for example, they can be arranged as follows. In addition, the method of arranging a plurality of heating parts 25 is not limited to the following method. First, a plurality of heating parts 25 may be arranged side by side along the flow path direction of the supply flow path 22. If a plurality of heating parts 25 are arranged in this way, the gas can be quickly heated to a predetermined temperature. In addition, a plurality of heating parts 25 may be arranged side by side in a direction perpendicular to the flow path direction of the supply flow path 22. Depending on the installation position of the heating section 25, the flow rate or flow velocity of the air passing through the heating section 25 may be different. However, if a plurality of heating sections 25 are arranged as described above, heating suitable for the flow rate, flow velocity, etc. of the air can be performed. For example, if a heating unit 25 with a high heating capacity is installed at a location with a large flow rate or a location with a fast flow rate, and a heating unit 25 with a low heating capacity is installed at a location with a small flow rate or a location with a slow flow rate, a plurality of heating units 25 can be used. Heat the air efficiently. Naturally, if a plurality of heating parts 25 are arranged side by side along the flow path direction of the supply flow path 22, and a plurality of heating parts 25 are also arranged side by side along the direction perpendicular to the flow path direction of the supply flow path 22, the above two can be obtained. The effect of the person.

＜Case without external box 4＞ Although the aforementioned volume reduction/volume reduction processing apparatus 1 is provided with an external box 4, the volume reduction/volume reduction processing apparatus 1 may be configured without the external box 4 (refer to FIG. 7). In this case, if a space capable of accommodating the covering box 2 is provided in advance of the tank, etc., and the covering box 2 is installed in this space, the volume reduction/volume reduction processing device 1 can also be used in the same manner as the case where the outer box 4 is provided. Act. Naturally, the volume reduction/volume reduction processing device 1 can also be operated without the external box 4.

＜Tilt sensor＞ The aforementioned volume reduction/volume reduction processing device 1 should preferably have an action stop function, which automatically stops when it falls over during action or the like. That is, a function is provided: when the volume reduction/volume reduction processing device 1 is tilted by a certain amount or more, it is determined that an overturn has occurred, the operation of the air flow forming part 21 of the heating air supply part 20 is stopped, and the heating by the heating part 25 is stopped. In this way, it is possible to prevent the situation in which the heated air supply part 20 remains in operation even if it is tipped over.

The sensor for detecting tipping is not particularly limited. For example, a sensor that detects when the bottom of the volume reduction/volume reduction processing device 1 floats more than a certain level; or a tilt sensor that detects the inclination of the volume reduction/volume reduction processing device 1 can be used.

Especially in the case of using a tilt sensor, it is advisable to install a tilt sensor on the cover 3 of the volume reduction/volume reduction processing device 1. If the tilt sensor is installed on the cover 3, not only will the volume reduction/volume reduction processing device 1 tip over, the cover 3 will be accidentally moved in the state where the heated air supply part 20 is operating (the state is about to be processed) When it is turned on, the operation of the heated air supply unit 20 may also be stopped. In other words, if the tilt sensor detects that the lid 3 is opened and becomes a predetermined angle, the operation of the heated air supply unit 20 can be stopped by the control unit 40.

The position where the tilt sensor is provided on the cover 3 is not particularly limited. For example, the tilt sensor can be provided inside the control part 40 in FIG. 1. In addition, the angle at which the operation of the heated air supply unit 20 is stopped is not particularly limited. For example, when the inclination with respect to the horizontal detected by the inclination sensor is 10° or more, the operation of the heating air supply unit 20 may be stopped.
