Description

Dry reduction processing device {DRYING VOLUME REDUCTION PROCESSING DEVICE}

The present invention relates to a dry reduction treatment apparatus. More specifically, the present invention relates to a dry and permissive treatment apparatus for drying waste containing moisture such as food waste.

Waste containing moisture, such as food waste generated at home, etc., is required to be reduced or dehydrated in order to reduce disposal costs. In order to meet these demands, various waste treatment methods have been developed.

As an example, a household food waste drying processor for crushing and drying food waste has been developed as a device for treating food waste discharged from home. For example, in order to treat food waste in a short time, a device for crushing and dehydrating food waste while stirring with a rotary stirring blade has been developed.

By the way, when food waste is crushed by the stirring blade, dehydration improvement can be expected, but there is a fear that the garbage is wrapped around the rotating shaft of the stirring blade. If it is wrapped in weak or soft waste, even if it is wrapped around the rotating shaft, it will not interfere with the shredding operation.However, if a strong fiber such as bamboo shoot leather or corn husk is wound, the shredding may be affected. . For example, due to the enveloping, the contact between the stirring blade and the waste may be inhibited and the crushing may not be sufficiently performed, or in the worst case, the rotational resistance of the rotating shaft may cause damage to the apparatus. In addition, a hard object (e.g., shells, etc.) may be caught between the stirring blade and the bottom of the container into which food waste is placed. In this case, the stirring blade or the bottom of the container may be damaged by the hard object. The problem also arises.

On the other hand, the apparatus which employ | adopted the method of drying food waste by firing hot air etc. without crushing food waste and evaporating moisture by the heat is developed (for example, patent documents 1-4).

By the way, in this apparatus, since the hot air is brought into contact with the surface of the waste and evaporated to dryness, the surface portion of the stacked waste can be dried, but the inside cannot be sufficiently heated. Then, in order to dry whole food waste, it takes very long time and there exists a possibility that it cannot dry enough even if it takes time.

It is also possible to dry the whole food waste by stirring food waste to expose the waste inside to the surface one by one.

In this case, however, a stirring blade or the like must be provided, and the same problem as described above occurs as in the case of crushing garbage.

In addition, in the above apparatus, if hot air of more than 100 degrees is used, the waste can be sufficiently dried, but the apparatus is expensive because a material which must withstand such hot air must be used. In addition, the air used for drying the waste is then discharged from the apparatus, but the temperature of the discharged air cannot be sufficiently lowered, so that the possibility of a person being burned by the high temperature exhaust cannot be denied.

In addition, the air drying the garbage contains the odor of the garbage, so it is preferable to deodorize it before discharge. However, in order to deodorize high-temperature air, it is necessary to use expensive oxidation catalysts, such as platinum and palladium, and the apparatus becomes more expensive.

According to the first invention, the heated air supplied into the processing container flows from the upper part of the processing container toward the bottom in one pass, and comes into contact with the processing object in the processing container, so that the heating air easily reaches the inside of the processing object. In addition, since the heated air is discharged from the bottom of the processing container, the heating air can be reliably brought into contact with the to-be-processed object located at the bottom of the processing container, thereby increasing the drying efficiency. Moreover, heat efficiency can be improved compared with the case where heating air is circulated and outer air is always heated and it is made into heating air.

According to the second invention, a part of the heating air is discharged to the exhaust mechanism by the distribution unit, and the outside air is supplied to the circulation passage by the air supply mechanism. That is, since a part of the circulating heating air is replaced with the outside air, the amount of moisture in the heating air can be lowered and the drying efficiency can be improved.

And the vent hole is formed in the other end of a container, and the clearance gap which can flow a heating air is formed between the other end of a container and a support plate. Therefore, heating air can be reliably passed through the to-be-processed object in a container. In addition, even when moisture is separated from the object in the container, the moisture can be stored in the support dish, thereby preventing the inside of the apparatus from being polluted by the water falling from the object.

According to the fifth aspect of the invention, the processing container can be detached from the apparatus, and the processing container can be used as a food waste bin or the like placed on a kitchen sink or the like. And the processing container which put the garbage can be installed in an apparatus as it is, and waste processing can be made easy. In addition, since the storage container can be removed from the support plate, the storage container from which the support plate has been removed can be installed in a kitchen sink or the like and used for removing water. When the waste is collected and heat-treated, the container should be transferred to the device. However, if the support plate is installed in the container, water can be dropped from the garbage in the container and can be transferred to the device without dropping water. Can be. In addition, since a rotating object such as a knife for shredding is not provided in the container, a commercially available nonwoven fabric or a bag such as a net, which is well used as a food waste bin, can be disposed in the container.

The dry reduction processing apparatus of this embodiment is an apparatus for processing the to-be-processed object containing moisture, and drys and to-treat a to-be-processed object by making a heating air contact a to-be-processed object.

The object to be treated is not particularly limited as long as it contains water. Examples of the object to be processed include food wastes discharged from homes, but are not limited thereto.

(Schematic explanation of the drying reduction processing apparatus 1)

As shown in FIGS. 1-3, the dry reduction processing apparatus 1 of this embodiment accommodates the processing container 10 for putting a to-be-processed object and performing a dry reduction processing, and this processing container 10 inside. The case 2 which has the storage space 2h for this is provided. The inside of the case 2 is a heating air supply means 20 for supplying heated heating air in the processing container 10, and circulating the heating air between the processing container 10 and the heating air supply means 20. A circulation passage, an exhaust mechanism for exhausting the heated air in the circulation passage to the outside, and an air supply mechanism for communicating between the circulation passage and the outside are provided.

In addition, the heating air supply means 20, the circulation flow path, the exhaust mechanism, and the air supply mechanism do not have to install all the components constituting them in the case 2. However, if all the components are provided in the case 2, since the handleability of the drying reduction processing apparatus 1 can be improved and space saving can also be carried out, it is preferable.

(Description of Processing Container 10)

First, the processing container 10 will be described.

The processing container 10 is a member detachably installed from the storage space 2h of the case 2. That is, the processing container 10 can be taken out from the apparatus. If the processing container 10 is placed in a kitchen sink or the like, it can be used as a food waste bin. And the processing container 10 which put the garbage can be installed in an apparatus as it is, and waste processing can be made easy.

Next, the structure of the processing container 10 is demonstrated in detail.

As shown in FIG. 5, the processing container 10 includes a tubular accommodating container 11 and a support plate 12 provided at a lower end of the accommodating container 11.

As shown in Fig. 5, the accommodating container 11 is a member formed in a cylindrical shape. The receiving container 11 has an opening 11h serving as a supply port as described in the claims at one end thereof (the upper end in Fig. 5, hereinafter referred to as the upper end), and the other end (lower end, lower end in Fig. 5). Bottom portion 11b is provided. The bottom part 11b of the accommodating container 11 is provided with many through-holes which become an exhaust port in the claim, and can pass through liquids, such as water, and air. In addition, the size of the through hole is not particularly limited, but may be formed to a size (for example, about 3 to 20 mm) such that the object does not fall out.

Moreover, the leg part 11c is provided in the bottom part of the storage container 11. Although the height of this leg part 11c is not specifically limited, For example, it is about 10-20 mm.

And the storage container 11 should just be a cylindrical shape, The cross-sectional shape is not specifically limited. For example, circular may be sufficient, and polygons, such as a triangle, a rectangle, and a hexagon, may be sufficient.

In addition, it is preferable that the accommodating container 11 can be provided with the bag N, such as a commercial drainage (dehydration) net | network, as shown in FIG. Then, after completion of the drying process, the garbage can be removed from the accommodating container 11 for each bag N, so that it can be disposed of as it is and the disposal of the waste after the treatment becomes easy.

As shown in FIG. 5, a support plate 12 is provided at the lower end of the accommodation container 11. The support plate 12 is a member formed of a material which does not permeate liquid such as water, and can hold the liquid therein.

Specifically, the wall part 12a is provided so that the base dish 12 may surround the inner bottom along the outer periphery. Although the height of this wall part 12a is not specifically limited, It is formed so that it may become longer than the leg part 11c of the bottom part of the storage container 11. For example, it is about 20-30 mm. Moreover, the inner diameter of the wall part 12a is provided larger than the outer diameter of the lower end of the accommodation container 11. For example, it is formed about 20-40 mm larger than the outer diameter of the lower end of the accommodating container 11.

With the above-described configuration, when the object is injected into the interior of the opening 11h at one end of the container 11, the object can be accommodated in the container 11.

Then, when the housing container 11 is placed on the support plate 12, the bottom portion 11b of the storage container 11 is supported on the support plate 12 by the leg portion 11c provided at the bottom of the storage container 11. ) And the bottom gap 12h is formed between the inner bottom of the support dish 12. Moreover, since the inner diameter of the wall part 12a is larger than the outer diameter of the lower end of the accommodating container 11, the side gap 12s is formed also between the outer peripheral surface of the accommodating container 11 and the wall part 12a.

For this reason, when heating air is supplied from the opening 11h of the accommodating container 11, it passes through the bottom part 11b, and discharges out of the support dish 12 through the bottom gap 12h and the side gap 12s. A flow of heating air is formed. Therefore, when the to-be-processed object is put in the accommodating container 11, heating air can be reliably passed through the to-be-processed object.

Moreover, since the wall part 12a is provided along the outer periphery of the support dish 12, even if moisture falls from the to-be-processed object in the storage container 11, it can hold | maintain this moisture in the support dish 12. . Therefore, even if the processing container 10 is put in the accommodation space 2h of the case 2, the inside of the storage space 2h can be prevented from becoming polluted by the water falling from the to-be-processed object.

The leg part 11c provided in the bottom part of the accommodating container 11 mentioned above is corresponded to the clearance gap formation mechanism in the claim.

In addition, many through-holes, bottom gap 12h, and side gap 12s provided in the bottom part 11b of the accommodating container 11 correspond to the exhaust port mentioned in the claim.

(Different shape of the gap forming mechanism)

The process container 10 mentioned above demonstrated the case where the leg part 11c was provided in the bottom part of the accommodating container 11 as a clearance formation mechanism. The clearance gap formation mechanism is not specifically limited as long as it floats the bottom part 11b of the accommodating container 11 from the inner bottom of the base 12, and can form the bottom gap 12h between them.

For example, the following structure may be formed in the support dish 12, and it may be set as a clearance formation mechanism.

As shown in FIG. 6, a pedestal portion 12d having a holding surface ds higher than the inner bottom is provided on the inner bottom of the support plate 12. 12 d of these pedestal parts are provided in multiple places in the state which spaced to some extent along the circumferential direction of the base plate 12. As shown to FIG.

When such a base part 12d is provided, when the bottom part 11b of the storage container 11 is raised to the holding surface ds of the base part 12d, the bottom part 11b and the support dish of the storage container 11 will be provided. A bottom gap 12h can be formed between the inner bottoms of 12. In addition, since the bottom gap 12h and the side gap 12s communicate with each other by the space between the pedestals 12d, the heated air passing through the bottom 11b of the storage container 11 is transferred to the bottom gap ( 12h) and the side gap 12s can be discharged out of the support plate 12.

(Other shapes of fixing mechanism)

The storage container 11 and the support plate 12 do not have to be fixed, but if both are configured so that the waste in the storage container 11 does not need to hold the support plate 12 when moving the processing container 10. Water falling from the base plate 12 can be received. In addition, if only the container 11 is included, the support dish 12 can also remove the processing container 10 from the apparatus. Therefore, the conveyance of the processing container 10 becomes easy, and the operation | work which attaches and detaches the processing container 10 to an apparatus also becomes easy.

Then, if the supporting plate 12 is removed from the housing container 11 and the housing container 11 is placed on a kitchen sink or the like, the housing container 11 can be used for removing water.

The method of fixing both is not specifically limited, Both may be formed integrally and may be made to be removable.

In the case of attaching and detaching both, the mechanism which fixes both is not limited, What is necessary is just to be able to attach or detach the storage container 11 and the support dish 12, for example, the following structures are mentioned.

As shown in Fig. 6, a groove 11g is provided around the lower end of the container 11. On the other hand, a projection 12p is provided on the inner surface of the wall portion 12a of the support plate 12 to which the groove 11g is coupled. have. Then, when the projection 12p of the support plate 12 is combined with the groove 11g of the accommodation container 11, both can be fixed, and when the projection 12p is detached from the groove 11g, it can separate.

In addition, although the case where the processing container 10 has the support plate 12 was demonstrated in the said example, you may use only the storage container 11 as the processing container 10 without using the support plate 12. As shown in FIG. . Also in this case, if the leg part 11c is provided in the bottom part of the accommodating container 11 as mentioned above, heated air in the through-hole of the accommodating container 11 (namely, it corresponds to the exhaust port of the processing container 10). Can be discharged.

(About case 2)

As shown in Fig. 1 and Fig. 2, the case 2 of the drying reduction processing apparatus 1 of this embodiment is a vertical container having a substantially rectangular shape, and is formed of an upper case 2A and a lower case 2B. .

The upper case 2A has a housing space 2h, and is a case in which the heating air supply means 20 and the circulation flow path are incorporated. The processing part 1A is comprised by this upper case 2A, the heating air supply means 20, etc. The lower case 2B is a case in which the cooling mechanism of the exhaust mechanism described later is incorporated, and the cooling unit 1B is constituted by the lower case 2B, the cooling mechanism and the like.

The processing unit 1A and the cooling unit 1B are stacked so that the upper surface of the cooling unit 1B and the lower surface of the processing unit 1A face each other. In addition, between the upper surface of the cooling unit 1B and the lower surface of the processing unit 1A, an exhaust passage 42 for discharging the air cooled by the cooling mechanism to the outside, and an inflow passage 51 of the air supply mechanism in communication with the outside are provided. Although formed, the detail is mentioned later.

In addition, although the upper case 2A and the lower case 2B may be integrated as the case 2, it is preferable that the upper case 2A and the lower case 2B are detachably attached to each other. Then, the maintenance property of the processing part 1A and the cooling part 1B can be improved.

(Description of Processing Unit 1A)

Next, the processing unit 1A will be described.

1A of process parts are provided with the upper case 2A which has the accommodating space 2h, the heating air supply means 20 built in this case 2A, and the circulation flow path.

(Explanation of upper case 2A)

The upper case 2A is a case formed in a substantially rectangular shape and has an accommodating space 2h having an opening at an upper end thereof. This accommodation space 2h is a space where the processing container 10 is accommodated as mentioned above. This accommodating space 2h is formed to a size such that a gap 30h is formed between the outer peripheral surface of the processing container 10 and the inner surface of the accommodating space 2h when the processing container 10 is disposed therein. The reason will be described later.

As shown in Fig. 1, the upper case 2A is provided with a lid 2a capable of blocking the upper opening of the accommodation space 2h from communicating with the outside. When the lid 2a is closed, the lid 2a has a structure in which the lid 2a can be hermetically blocked between the inside and the outside of the storage space 2h.

The inner surface of this lid 2a is provided with the heating air supply passage 20a which supplies the heating air supplied from the heating air supply means 20 toward the inside of the accommodating space 2h. The heating air supply passage 20a is connected to the heating air supply means 20 when the lid 2a is closed, and is disconnected from the heating air supply means 20 when the lid 2a is opened.

This heating air supply passage 20a has a discharge port 20f for discharging the heating air, and the discharge port 20f is opened to face downward. Specifically, when the discharge port 20f closes the lid 2a while the processing container 10 is accommodated in the accommodation space 2h, the discharge port 20f is located in the processing container 10, and the storage space 2h is provided. It is provided in the position which can exhale heating air to the to-be-processed object in the processing container 10 arrange | positioned at the toner.

In addition, when the lid 2a is closed in a state where the lid 2a is accommodated in the accommodation space 2h, the lid 2a is formed of the inner surface of the lid 2a and the accommodation vessel 11 of the treatment vessel 10. It is preferable to have a structure in which a gap is formed between the upper end and the air so as to allow air to pass through, which will be described later.

(Description of heated air supply means 20)

In 2A of upper cases, the heating air supply means 20 is provided in the space isolate | separated from this accommodating space 2h in the side of the said accommodating space 2h.

The heated air supply means 20 includes, for example, a blower 21 that sucks air such as a blower (sirocco fan) from the intake port and discharges it from the exhaust port, an exhaust port of the blower 21 and the heated air supply passage 20a. ) And a heater (23) provided in the blower passage (22).

The blower 21 has an intake port communicating with the storage space 2h of the case 2. That is, it is provided so as to suck air in the storage space 2h and return the air to the storage space 2h via the blowing passage 22 and the heating air supply passage 20a.

In addition, although the position which arrange | positions the intake port of the blower 21 is not specifically limited, If it arrange | positions below the accommodating space 2h, the heated air supplied to the accommodating space 2 will be the to-be-processed object of the processing container 10. Since it becomes easy to flow inside, it is preferable.

The blowing passage 22 is a passage provided in the case 2, and one end thereof is connected to the exhaust port of the blower 21. The other end of the air passage 22 is disposed above the case 2, and is provided so as to be disconnected from the heating air supply passage 20a when the lid 2a is opened and closed. Specifically, when the lid 2a is closed, the opening 22a provided at the other end of the blowing passage 22 and the passage 20i provided in the heating air supply passage 20a are brought into close contact with each other, and both lids are opened. It is provided so that a space may arise between them (refer FIG. 7).

Moreover, although the distribution part 30 which discharges a part of heating air supplied from the blower 21 to the cooling part 1B is provided in the blowing passage 22 (refer FIG. 3), it mentions later.

The heater 23 is a mechanism capable of heating air, and is mounted between the blowing passages 22. This heater 23 has a passage through which air blown from the blower 21 passes, and has a heating function for heating the air passing through the passage to a predetermined temperature. As this heater 23, although a ceramic heater and a coil heater are mentioned, it does not specifically limit, for example.

Because of the structure as described above, when the heating air is supplied from the heating air supply means 20 to the opening 11h of the receiving container 11, the heating air passes through the inside of the object in the receiving container 11 and the bottom portion ( Pass 1b).

The heated air having passed through the bottom portion 11b passes through the bottom gap 12h and the side gap 12s and is discharged out of the support plate 12. The heated air discharged out of the support plate 12 flows into the gap 30h between the outer circumferential surface of the processing container 10 and the receiving space 2h and the inner surface.

Then, since the intake port of the blower 21 communicates with the accommodation space 2h, the heated air discharged out of the support plate 12 is sucked by the blower 21 and heated by the heater 23, and then again. It is supplied to the opening 11h of the accommodation container 11. In other words, the heating air circulates between the heating air supply means 20 and the receiving container 11.

As described above, the heating air circulates between the heating air supply means 20 and the accommodating container 11 while flowing the inside of the accommodating container 11 in one direction from the upper portion toward the bottom portion 11b to process the processing container 11. Since it contacts with the to-be-processed object in inside, it becomes easy to spread heating air to the inside of a to-be-processed object. And since heated air is discharged from the bottom part of the accommodating container 11, even if the to-be-processed object located in the bottom part 11b of the accommodating container 11 can be made to contact heating air certainly, drying efficiency can be improved. .

In addition, since the heating air is circulated, the thermal efficiency can be improved as compared with the case where all the heating air is exhausted.

In order to dry-process the to-be-processed object only by heating air, rotating objects, such as a crushing knife, were not installed in the accommodating container 11. For this reason, processing can be performed to the accommodating container 11 with the bag N, such as a commercial nonwoven fabric and net which are used for food waste well. Then, since the garbage can be taken out for each bag N after the completion of the drying process, the disposal of the garbage after the treatment becomes easy.

In addition, since some of the heating air is discharged to the cooling unit 1B by the distribution unit 30 described above, it is supplied to the processing container 10 in the accommodation space 2h rather than the heating air discharged from the accommodation space 2h. Less heating air is added. For this reason, in the upper case 2A of the processing part 1A, an air supply mechanism for supplying air corresponding to the difference between them from the outside into the storage space 2h is provided. Details of this air supply mechanism will be described later.

In addition, the temperature of the heating air supplied from the heating air supply means 20 is not specifically limited. The temperature of heating air should just be lower than the heat-resistant temperature of the material used by each part of an apparatus. For example, if the temperature of the heating air is relatively low temperature (for example, about 60 to 80 ° C), a low-cost material (for example, polypropylene (PP), etc.) can be used as the material used for each part of the apparatus. It is preferable because there is. If the temperature of the heated air is in the above temperature range, the bag N or the like is not damaged by heat even if a commercially available bag N for removing moisture is exposed to the heated air. Then, the drying process can be performed even with the bag N for water removal removed to the accommodating container 11 of the processing container 10.

(Description of Bypass Path)

In the drying reduction processing apparatus 1 of this embodiment, the accommodating container 11 through the opening 11h of the accommodating container 11 in the discharge port 20f of the heating air supply passage 20a of the heating air supply means 20. The structure which supplies heating air to the to-be-processed object inside, and makes the to-be-processed object pass through this heated air is employ | adopted. For this reason, when the quantity of the to-be-processed object is large, the pressure loss at the time of passing through the to-be-processed object becomes large, and the quantity of the heating air which passes through the to-be-processed object becomes small. Then, the amount of heating air returned to the suction port of the blower 21 of the heating air supply means 20 becomes smaller than the heating air discharged from the discharge port 20f, and the suction port of the discharge port 20f and the blower 21 is reduced. The pressure loss between them becomes large, and the load on the blower 21 becomes large. In order to reduce the load, heating air supply means 20 must be controlled to reduce the flow rate of the heating air supplied from the outlet 20f to the receiving container 11 so as to correspond to the amount of heating air passing through the object. Control is complicated.

In the drying reduction processing apparatus 1 of this embodiment, when the lid 2a is closed in the state where the processing container 10 is accommodated in the accommodation space 2h, the inner surface of the lid 2a and the processing container 10 are separated. It has a structure in which a clearance enough to pass air is formed between the upper end of the accommodating container 11. Then, the air that could not pass through the workpiece flows along the surface of the workpiece and dries the surface, and passes through the gap to between the outer circumferential surface of the processing container 10 and the receiving space 2h and the inner surface. Since it flows through the clearance gap 30h formed in the back, and is returned to the suction port of the blower 21, the amount of the heated air discharged from the discharge port 20f and the return air to the suction port of the blower 21 can be substantially matched. Then, since the pressure loss between the discharge port 20f and the suction port of the blower 21 can be reduced, an appropriate drying process can be performed without reducing the flow rate of heating air.

The clearance 30h between the outer circumferential surface of the processing container 10 and the storage space 2h and the inner surface of the above-described processing container corresponds to a circulation flow passage in the claims.

Further, the gap 30h between the outer circumferential surface of the processing container 10 and the storage space 2h and the inner surface constitute a part of the bypass path as claimed in the claims, and the gap 30h and the processing container ( 10 is patented by a gap formed between the inner surface of the lid 2a and the upper end of the accommodating container 11 of the processing container 10 when the lid 2a is closed in the accommodating space 2h. Bypass paths are formed in the claims.

In addition, the structure of a circulation flow path and a bypass path is not specifically limited, Any structure can be employ | adopted as long as it has a function as mentioned above.

(Description of the Cooling Unit 1B)

Next, the cooling unit 1B will be described.

As described above, the cooling unit 1B includes a lower case 2B and a cooling unit of an exhaust mechanism incorporated in the lower case 2B.

(Explanation of exhaust mechanism)

In the lower case 2B of the cooling unit 1B, a cylindrical space 45h for forming a cooling mechanism is formed. The cylindrical deodorizing part 47 is provided in this space 45h. This deodorizing portion 47 is formed of a case portion 47a formed of a material having no cylinder-proof breathability, and an activated carbon 47b disposed therein.

As shown in Fig. 2, the deodorizing portion 47 is arranged such that its central axis coincides with the central axis of the space 45h. That is, the deodorizing portion 47 has a space 45h such that an annular space is formed between the outer surface of the case portion 47a of the deodorizing portion 47 and the wall of the lower case 2B serving as the outer shell of the space 45h. Will be installed in

Moreover, the deodorizing part 47 is provided so that the upper end may be provided in the upper end of the lower case 2B, and the lower end is spaced apart from the inner surface of the lower end of the lower case 2B.

In addition, the upper and lower surfaces of the deodorizing portion 47 are provided with a through hole for communicating between the inside of the case portion 47a and the outside of the case portion 47a. The through-holes and the like formed on the upper surface of the deodorizing unit 47 communicate with the exhaust port Ex for discharging air to the outside through the exhaust passage 42 as described later.

As shown in FIG. 2, in the lower case 2B, a partition wall 2w is provided to space a part of the space in the lower case 2B from the space 45h. This partitioning wall 2w is a wall which becomes the outer shell of the space 45h together with the wall of the lower case 2B. The partition wall 2w is provided with an opening 45a corresponding to the inlet port in the claims. The opening 45a is formed so that the air flows in the circumferential direction of the space 45h when the air flows into the space 45h from the opening 45a.

And the air passage 41 is provided in the surface opposite to the space 45h in the separation wall 2w so as to cover the opening 45a. The air passage 41 is configured such that heated air discharged from the above-described distribution unit 30 flows in.

Specifically, the distribution part 30 is provided with the inflow pipe 31 and the branch pipe 32, One end of the inflow pipe 31 is connected to the air passage 41. The other end of the inflow pipe 31 protrudes from the upper surface of the lower case 2B. Moreover, the branch pipe 32 is provided so that one end may communicate with the ventilation passage 22 in the upper case 2A, and the other end may protrude from the lower surface of the upper case 2A. In addition, the branch pipe 32 and the inflow pipe 31 are arranged such that when the upper case 2A and the lower case 2B are connected, both are connected. That is, when the upper case 2A and the lower case 2B are connected, the blowing passage 22 and the space 45h form the inflow pipe 31, the branch pipe 32, the air passage 41, and the opening 45a. It is communicated through).

Since the above structure is connected, when the upper case 2A and the lower case 2B are connected, it flows as follows, and heating air is discharged | emitted to the outside.

A part of the heating air in the blow passage 22 flows into the air passage 41 by flowing part of the branch pipe 32 and the inlet pipe 31 of the distribution part 30 in this order (dotted arrow in FIG. 3). And flows into the space 45h from the opening 45a. The heated air introduced into the space 45h flows into the deodorizing portion 47 in the space 45h, and the air passing through the deodorizing portion 47 flows through the through hole into the exhaust flow passage 42. And the air which flowed into the exhaust flow path 42 flows in the exhaust flow path 42 toward the exhaust port Ex, and is discharged | emitted outside through the exhaust port Ex.

Then, when heated air flows into the space 45h from the opening 45a, the heated air flows along the inner surface of the outer shell of the space 45h because the heated air flows in the circumferential direction of the space 45h. The outer shell of the space 45h is formed by the wall of the lower case 2B whose outer surface is in contact with the outside air except for the separating wall 2w in which the opening 45a is provided. Then, the heated air is cooled by contacting the inner surface of the outer shell of the space 45h, and by flowing along the inner surface of the outer shell of the space 45h, the contact efficiency with the outer shell of the space 45h can also be improved. . Therefore, the cooling of the heating air can be performed more efficiently than in the case of simply supplying the heating air into the space 45h. For example, if the temperature of the heating air is relatively low, it is also possible to lower the temperature of the heating air entering the deodorizing portion 47 in the space 45h to 40 ° C or less.

In addition, since the heated air passes through the deodorizing unit 47 before being discharged to the outside through the exhaust port Ex, the air can be deodorized before the heating gas is discharged to the outside. In addition, the heated air is cooled in the space 45h and then introduced into the deodorizing portion 47. For this reason, when the temperature of heating air can be reduced to 40 degrees C or less in the space 45h, it becomes possible to use low-cost activated carbon as a deodorant of the deodorizing part 47. Then, even if it has the deodorizing part 47, the price of an apparatus can be held down.

In addition, the deodorant of the deodorizing part 47 is not limited to activated carbon, Any may be used and it is not specifically limited.

The wall surface which forms the cylindrical space 45h mentioned above is corresponded to the cooling tube mentioned in a claim.

Moreover, the cooling part mentioned in the claim is formed by the air passage 41, the opening 45a, and the cylindrical space 45h, This cooling part, the deodorizing part 47, the exhaust flow path 42, and the exhaust port By Ex, the exhaust mechanism as stated in the claims is formed.

(Heat exchange mechanism)

As described above, the amount of the heating air discharged from the accommodating space 2h generated by discharging part of the heating air to the cooling unit 1B by the distribution unit 30 and the processing container 10 in the accommodating space 2h. The difference from the amount of the heated air supplied to is supplemented by the air supplied from the outside into the accommodation space 2h by the air supply mechanism. In this case, the air supplied from the outside into the accommodation space 2h may be supplied directly into the accommodation space 2h, but is preferably supplied after being preheated by the following heat exchange mechanism.

As shown in Fig. 2, the lower surface of the upper case 2A is provided with a partition 2d for dividing the space therebetween when the lower surface of the upper case 2A and the lower case 2B are connected, and further, the partition 2d. Is disposed so that a part of the wall surface constituting at least two spaces of the divided spaces becomes the wall surface 2c of the upper case 2A.

An exhaust port Ex is formed in the wall surface 2c which forms this space as the exhaust flow path 42 using the space in which a part of the wall surface became the wall surface 2c of the upper case 2A. In addition, as another space in which a part of the wall surface becomes the wall surface 2c of the upper case 2A, a space sharing the exhaust flow path 42 and the wall surface (for example, the partition wall 2d) is provided as an inflow passage of the air supply mechanism ( 51, an air inlet in is formed in the wall surface 2c forming this space. And the communication passage 52 which communicates between the inflow passage 51 and the accommodating space 2h is provided in 2 A of upper cases.

Then, the outside air introduced into the inlet passage 51 from the air inlet in is exchanged with the heated air flowing in the exhaust passage 42 through the partition 2d forming the exhaust passage 42. Preheated. At the same time, the air in the inflow passage 51 is preheated by performing heat exchange with the heated air in the space 45h through the upper surface of the lower case 2B. That is, the air may be introduced into the inflow passage 51 from the air inlet in, and the outside air supplied into the accommodation space 2h through the communication passage 52 may be preheated and supplied to the accommodation space 2h. Then, the thermal efficiency of the apparatus can be improved as compared with the case where the outside air is supplied to the accommodation space 2h as it is.

In addition, with the above configuration, since the heat exchange structure is formed between the processing section 1A and the cooling section 1B, the space can be effectively utilized.

The position and shape of the partition 2d are not particularly limited. However, when the partition 2d is formed in a U-shape in plan view as shown in FIG. 4, the contact area between the air in the inflow passage 51 and the partition 2d is formed. It is preferable to reduce the flow resistance while increasing the degree to some extent.
