Description

  In the present invention, a storage unit is configured by horizontally arranging a plurality of storage bodies in which a space for storing a grain is formed by a side wall part and a floor part surrounding a side part, and the storage part is configured to be located above the storage part. And the grain supply position for supplying the grain to be conveyed is positioned along the grain conveyance direction. Grain supply means configured to be changeable and adjustable is provided, and a floor for each storage body is formed with a discharge port for discharging stored grain to the outside, and the The present invention relates to a grain storage facility in which an agitation unit for agitating stored grain is provided in a grain storage space inside at least some of the storage bodies.

The grain storage facility configured as described above is a facility for storing a large amount of grain for drying or storage in the storage unit. In such a grain storage facility, conventionally, for example, as shown in FIG. Each of the storage bodies 1 is configured to store a set amount of grains in a grain storage space inside the storage body 1, and an outlet 69 for discharging the stored grains to the outside is provided for each of the storage bodies 1. In the case where the stored grains are discharged to the outside, they are discharged from one discharge port 69. In addition, as a discharge means for discharging the grain from the discharge port 69 to the outside, a discharge structure by blowing air or a discharge structure by mechanical conveyance by a screw or the like is used.
Further, the stirring means 10a for stirring the stored grain is distributed and arranged along the direction orthogonal to the grain conveying direction so as not to interfere with the grain supply operation by the grain supply means 4, for example, screw type stirring. The moving body 14a that supports the apparatus 11a is configured to be freely movable along a direction orthogonal to the grain conveying direction.

  Grains stored in the above-mentioned grain storage facilities are appropriately carried by multiple producers. Even if grains are produced by the same producer, the variety and quality of the grains, for example, the moisture content and taste of the grains May be different. And recently, in such a grain storage facility, in addition to sorting grains by producer, it can be stored in a state where it is sorted into different types of grains according to differences in grain varieties, quality, etc. It may be desirable to have as many grain storage spaces as possible. Further, as described above, it is not necessary to increase the number of grain storage spaces for sorting, but it may be desired to increase the amount of storage in one grain storage space as much as possible.

In the conventional configuration, as described above, in order to increase the storage amount in one grain storage space as much as possible while increasing the number of grain storage spaces as much as possible, each storage body is made large. It is necessary to construct a large capacity one and increase the number of such large storage bodies.
However, if it does in this way, since each storage body becomes a large sized apparatus and it is necessary to provide many such large storage bodies, it has the disadvantage of causing the increase in cost as a whole equipment, and a large installation space There are also disadvantages that are required.

  Specifications that increase the number of reservoirs and make each reservoir smaller, and specifications that make each reservoir smaller and reduce the number of reservoirs It is conceivable to prepare a plurality of types with different specifications, such as, but in this way, a plurality of different specifications must always be prepared, and the members used for each specification Differently, there is a disadvantage that it is not possible to reduce the cost by sharing the members.

  Therefore, as a configuration for satisfying such a demand, each storage body is configured in a large size, and the internal storage space in each storage body is divided into a plurality of regions, for example, with a partitioning tool in the intermediate portion. It is conceivable to increase the number of storage spaces while utilizing the configuration of the storage body. That is, when the storage space is divided in the conventional configuration as shown in FIG. 29, the storage space is arranged in parallel (the left-right direction in FIG. 29) so that grains can be separately supplied by the grain supply means. It is possible to divide into However, in the conventional configuration, the number of outlets is one, and the pair of agitation means are arranged so as to distribute the storage space in a direction (vertical direction in FIG. 29) perpendicular to the storage body parallel arrangement direction. Therefore, the grain discharging process and the stirring process by the stirring means cannot be performed for each divided space.

  The present invention has been made paying attention to such a point, and the object of the present invention can be coped with when it is desired to increase the number of spaces for storing grains as much as possible with a rational configuration. However, a grain storage facility that can maximize the amount of storage in one grain storage space and that can properly perform agitation processing and discharge processing can be achieved at low cost by sharing components. The point is to provide.

In the grain storage facility of the present invention, a storage part is configured by arranging a plurality of storage bodies in which a grain storage space is formed by a side wall part and a floor part surrounding the side part in the horizontal direction, and the storage part is located above the storage part. The grain is transported along the direction in which the storage bodies are arranged, and the grain to be transported is supplied to the storage unit from the upper side, and the grain supply position for supplying the grain to be transported is the grain transport direction. Grain supply means configured to be freely adjustable in position change is provided along the floor, and a discharge port for discharging the stored grain to the outside is formed in the floor portion of each storage body. The space for storing grains inside is provided with stirring means for stirring the stored grains,
The first characteristic configuration corresponds to each of the plurality of storage areas so that the storage body can be used by dividing the space for storing the grains into a plurality of storage areas arranged along the grain conveyance direction. The agitation means is provided so as to correspond to each of the plurality of storage regions of the reservoir that is configured to include the discharge port and is provided with the agitation means, and each agitation means is located above the storage portion. A movable body that is reciprocally movable along the grain conveying direction and a plurality of screw type stirring devices that are supported in a suspended state by the movable body in a state that intersects the grain conveying direction And a partition body that partitions a space near the upper part of the floor surface of each of the storage bodies in correspondence with the plurality of storage areas is provided.

According to the first characteristic configuration, when the grain storage space of the storage body is used as one region to store the grain, the grain is supplied by the grain supply means, and is stored in the grain storage space. It can be stored in a large space of almost the entire area. At this time, the plurality of stirring means can be moved along the grain conveying direction so as not to obstruct the supply.
In addition, the grains stored in the space for storing grains can be well stirred by a plurality of stirring means, and when the stored grains are discharged to the outside, they are discharged through two discharge ports. Or can be discharged only from one outlet. As described above, according to the use situation at that time, it is possible to select a state of discharging through the two outlets and a state of discharging only from the one outlet. If the configuration is such that the wind is exhausted using the wind force that is ventilated, the wind by the ventilation means is concentrated on one discharge port rather than acting on two discharge ports simultaneously. It is possible to increase the wind power and perform the discharge work efficiently.

  And if the partition which divides these some storage areas is provided so that the space for grain storage can be divided and used for a plurality of storage areas arranged along the grain conveyance direction, each of the plurality of storage areas is independent. It can be used as a storable space. Each storage area partitioned in this way can be supplied in a state of being separately sorted by a grain supply means configured to be able to change and adjust the position of the grain supply along the grain conveyance direction. A plurality of agitation means are provided corresponding to each of the plurality of storage areas, and each agitation means is reciprocated along the grain conveyance direction by a moving body that supports a plurality of screw-type agitation devices in a suspended state. Since it is provided so that it can be moved and moved, it can be retreated to a position where it does not interfere with the grain supply by the grain supply means, and each agitation means can separately stir the grains stored in each storage area. Can do. In addition, since a plurality of screw-type stirring devices are supported by a common moving body, the configuration can be simplified by sharing the members as compared with the case where each of the plurality of screw-type stirring devices has a moving body. . Furthermore, the grain stored in each storage area can be discharged to the outside separately from the discharge port provided corresponding to each of the plurality of storage areas.

  For example, if each reservoir is composed of a large one, the amount of storage in one grain storage space is made as large as possible by storing the grains using almost the entire area of the storage space for storing grains. Can be made. And by dividing and using a plurality of storage areas, it is possible to handle the case where it is desired to increase the number of grains storage space as much as possible without increasing the number of storage bodies as much as possible. Moreover, since the state of using almost the entire space for storing grains in the storage body and the state of using a plurality of storage areas in a divided manner can be changed depending on the presence or absence of an intermediate partition, other members must be shared. Thus, the cost can be reduced by sharing the members.

  Therefore, while it is possible to cope with the case where it is desired to increase the number of spaces for storing grains as much as possible, the amount of storage in one space for storing grains can be increased as much as possible, and stirring can be performed. A grain storage facility that can properly perform processing and discharge processing can be provided at low cost by sharing components.

Further, according to the first characteristic configuration of the present invention, the partition body partitions the space near the upper part of the floor in correspondence with a plurality of storage areas, so that almost the entire space for storing grain in the storage body is used. In the case of storing grains, when the grains are discharged from only one outlet, the partitioning body can smoothly perform the discharging operation without being affected by the grains in other storage areas. In particular, in the case of a configuration in which the air ventilated by the ventilating means is used for discharging, the partition body prevents the wind from being supplied to other storage areas, and a smooth discharging operation can be performed. .

  In the second characteristic configuration of the present invention, a storage portion is configured by horizontally arranging a plurality of storage bodies in which a space for storing grains is formed by a side wall portion and a floor portion surrounding the side portion, and above the storage portion. It is configured to feed the grain along the direction in which the storage bodies are arranged and to feed the grain to be conveyed from the upper side to the storage unit, and to feed the grain supply position for supplying the grain to be conveyed Grain supply means configured to be adjustable in position change along the direction is provided, and a floor for the storage body is formed with a discharge port for discharging stored grain to the outside. In a grain storage facility provided with an agitation means for agitating stored grain in an internal grain storage space, the storage body lines up the grain storage space along the grain conveyance direction. Can be used by dividing into multiple storage areas Thus, it is configured to provide the discharge port corresponding to each of the plurality of storage areas, and in the state where the storage space for storing grains of the storage body corresponds to the plurality of storage areas, A partition wall is provided for partitioning across the entire area of the abdomen, and each of the agitating means intersects the grain conveying direction with a moving body that is located above the reservoir and can be reciprocated along the grain conveying direction. And a plurality of screw type stirring devices supported in a suspended state by the moving body in a state of being arranged in a direction.

  According to the second feature configuration, the grain storage space of the storage body is configured to freely adjust the position of the grain supply position along the grain conveyance direction in a plurality of storage areas partitioned by the partition wall. Grains can be supplied and stored in a state of being sorted by the grain supply means. A plurality of agitation means are provided corresponding to each of the plurality of storage areas, and each agitation means is a reciprocating movement operation along the grain conveyance direction by a moving body that supports a plurality of screw type agitation devices in a suspended state. Since it is provided freely, each agitation means can separately agitate the grain stored in each storage area. Since the plurality of screw-type stirring devices are supported by a common moving body, the configuration can be simplified by sharing the members as compared with the case where each of the plurality of screw-type stirring devices has a moving body. Furthermore, the grain stored in each storage area can be discharged to the outside separately from the discharge port provided corresponding to each of the plurality of storage areas.

  Then, by removing the partition wall, it is possible to store the grain using almost the entire area of the grain storage space of the storage body. In such a state, it can be stored in a large space of almost the entire area in the space for storing grains. In addition, the grains stored in the space for storing grains can be satisfactorily stirred by a plurality of stirring means. When the stored grains are discharged to the outside, they are discharged simultaneously through a plurality of discharge ports. It is also possible to make it discharge, or to discharge only from one discharge port. Since various use states can be selected, such as discharging through a plurality of discharge ports simultaneously or discharging from only one discharge port in this way, for example, wind power ventilated by the ventilation unit as the discharge unit In the case of a configuration that uses exhaust air, the wind force is increased by concentrating and acting on one discharge port rather than simultaneously operating the wind from the ventilation means on a plurality of discharge ports. It is also possible to efficiently perform the discharging operation.

  Therefore, by dividing the storage space for storing grain in the storage body into a plurality of storage areas, the number of storage spaces for storing grains can be increased as much as possible. By storing grains using almost the entire space for grain storage in the body, it is possible to cope with the case where it is desired to increase the amount of storage in one grain storage space as much as possible. Since the state of using almost the entire space for storing grains in the storage body and the state of using a plurality of storage areas in a divided manner can be changed depending on the presence or absence of an intermediate partition wall, other members must be shared Thus, the cost can be reduced by sharing the members.

  Therefore, while it is possible to cope with the case where it is desired to increase the number of spaces for storing grains as much as possible, the amount of storage in one space for storing grains can be increased as much as possible, and stirring can be performed. A grain storage facility that can properly perform processing and discharge processing can be provided at low cost by sharing components.

In addition to the first or second feature configuration described above, the third feature configuration of the present invention includes:
The stirring means is characterized in that each of the screw type stirring devices is supported by the movable body so as to be reciprocally movable in a direction perpendicular to the grain conveying direction.

  According to the third characteristic configuration, the moving body is reciprocated along the grain conveying direction, and each screw type stirring device is reciprocated in the direction perpendicular to the grain conveying direction with respect to the moving body. As a result, the screw-type agitator moves in the grain conveying direction and the direction orthogonal thereto, so that even a small number of screw-type agitators can agitate almost all parts of the storage space. Processing can be performed.

  In addition, instead of such a configuration, a configuration in which a large number of screw type stirring devices are arranged in parallel in a fixed position along a direction orthogonal to the grain conveying direction is also conceivable. However, according to the above configuration, the stored grains can be stirred in almost all regions with a simple configuration using a small number of screw type stirring devices. It becomes possible.

In addition to any of the first to third feature configurations described above, the fourth feature configuration of the present invention includes:
A ventilation guide that guides the floor portion in each of the plurality of storage areas to flow to the upper side of the floor through the grain discharge gas supplied by ventilation from the lower side of the floor and to flow toward the outlet side on the floor surface. The cereal is provided with ventilation guide means for guiding the ventilation of the cereal discharge gas vented by the ventilation means to an underfloor portion of the floor portion, and the ventilation guide means is circulated by the ventilation means. The exhaust gas is configured to be selectively supplied to the plurality of storage regions.

  According to the fourth characteristic configuration, the grain discharge gas ventilated by the ventilating means is ventilated and guided to the underfloor portion of the floor portion in each of the plurality of storage areas by the ventilating guide means, and the ventilating guide portion formed on the floor portion Is passed through the upper side of the floor and is guided to flow toward the outlet side on the floor surface. Grain is flow-guided toward the discharge port and discharged by the grain discharge gas flow-guided on the floor surface.

  Further, since the ventilation guide means is configured to selectively supply the grain discharge gas to the plurality of storage areas, for example, the grain discharge gas is caused to flow in each of the plurality of storage areas. The system is used by switching between a state in which grains in each storage area are discharged at the same time and a state in which the grain discharge gas is allowed to flow only in one of the storage areas and the grains in only that storage area are discharged. It is possible to use them accordingly. In particular, when the grain is discharged to the outside in the form of storing the grain using the space for storing the grain of the storage body as one region, rather than causing the wind from the ventilation means to act on a plurality of outlets simultaneously. By concentrating and acting on one discharge port, there is an advantage that the wind power can be increased and discharge work can be performed efficiently.

The air supplied from the air is passed upward, and the direction is changed toward the discharge port 69 to blow air. A discharge shutter 36 that can freely open and close the discharge path is provided below each discharge port 69.

The storage space inside each storage bin 1 is provided with a stirring means 10 that stirs the grain while moving in the vertical direction. The agitating means 10 has two directions in which agitating screw 11 as a screw type agitating device for agitating the grain stored in the storage space while rotating around an axis along the vertical direction is substantially orthogonal in a plan view. It is provided so that it can be moved and operated freely.
More specifically, as shown in FIGS. 16 and 17, a pair of agitation screws 11 are supported by a support frame 12 so as to be rotatable around an axis along the vertical direction. It is configured to be movable along a parallel direction (hereinafter referred to as Y direction) and a direction substantially orthogonal thereto (hereinafter referred to as X direction). In other words, the pair of stirring screws 11 are supported on the support frame 12 at appropriate intervals along the X direction so as to be rotatable about the axis along the vertical direction, and each stirring screw 11 is driven to rotate individually.

On the other hand, the ventilation control damper 46 is opened, and the blower 32 and each electric motor are operated to perform ventilation drying. Then, when the discharge mode is commanded, as shown in FIG. 14, only the discharge shutter 36 and the ventilation control damper 46 of the storage bin 1 selected by the selection switch 54c are opened, and all other discharge discharges are made. The shutter 36 and the ventilation control damper 46 are closed. In this way, the flow air of the blower 32 is introduced from the lower side of the floor portion 31 of the selected storage bin 1, and the grain is caused to flow toward the discharge port by the air, whereby the grain in the storage bin 1. Can be discharged completely.

As shown in FIG. 5 and FIG. 6, the storage bin 1 includes a plurality of column members 5 and beam members 6 that connect the column members 5 to each other, so that a rectangular frame portion for assembling the panels is defined. A panel P formed in a hollow rectangular shape is assembled inside the frame portion to constitute a side wall portion of a storage space for storing grains for drying or storage. That is, the column member 5, the beam member 6, and the panel P are assembled at the installation location, thereby forming a substantially rectangular peripheral wall portion in plan view, and drying or storage in an area surrounded by the peripheral wall portion. Therefore, a grain storage space Di for storing grains is formed. In addition, a floor frame portion UK for arranging the air guide path 42 for performing the air flow for drying is formed below each storage space Di.

  Here, in the state where the panel P is assembled to the frame portion, the panel P is hardly loaded in the vertical direction and the horizontal direction, and only the pressure in the panel thickness direction due to the stored grain is applied. Thus, the required strength can be sufficiently ensured even with the panel P that has been made hollow and reduced in weight as will be described later. In addition, the column member 5, the beam member 6, and the panel P are shared by several storage space Di arrange | positioned adjacently.

Next, the panel P will be described with reference to FIGS.

In other words, a pair of plate-shaped part molding materials 7 that are bent so that the cross-sectional shape is substantially U-shaped are bonded together with the flat panel forming surface 7a positioned on the outer side to form a hollow shape. It is comprised so that it may become.
When the explanation is added, the outer peripheral portion of the plate-shaped portion molding material 7 is bent so that the cross-sectional shape is substantially U-shaped, and in the internal space formed by the bent portion 7b and the flange portion 7c in the vertical direction. In a state where four reinforcing members 8 having a substantially L-shaped cross section in the left-right direction are welded and arranged at appropriate intervals, and the reinforcing members 8 are welded to the plate-shaped portion molding material 7. The outer surface of the reinforcing material 8 forms substantially the same surface as the outer surface of the flange portion 7c of the plate-shaped portion molding material 7, and the reinforcing material 8 is formed on both sides of the plate-shaped portion molding material 7. It is made to be in the state over substantially the entire length between the portions 7c.
Then, the pair of plate-shaped portion molding materials 7 are opposed to each other in a state where the respective flange portions 7c and the reinforcing materials 8 are in contact with each other, and the bent portions 7b of the pair of plate-shaped portion molding materials 7 are welded to each other. A single rectangular hollow panel P is formed by connection.

And the panel P is set as the structure which the board | plate material 71 for attachment as a flange part is provided in the fixed state so that it may protrude toward the outward side from the outer peripheral part of the panel P in a right-and-left both-sides edge part. That is, the mounting plate 71 and the mounting pedestal 72 are welded and fixed so that the cross-section is substantially T-shaped, and the pedestal 72 is welded and fixed to the left and right end surfaces of the rectangular hollow panel. It is configured to be provided in a fixed state so as to protrude from the outer peripheral portion of the panel P toward the left and right lateral outer sides. The mounting plate 71 has a plurality of bolt insertion holes 73 formed therein.
The panel P has reinforcing members 8 arranged in parallel in the longitudinal direction and the lateral direction at substantially equal intervals in the hollow portion thereof, thereby reinforcing the panel P so as to have the same strength in the entire panel width direction. It is constituted as follows. The number of the reinforcing members 8 may be appropriately changed according to the required strength.

The assembly structure of the column member 5, the beam member 6, and the panel P will be described with reference to FIGS.

In such assembling work, a working scaffold is assembled so that the fastening work at a high position can be performed in a state where the assembling work is located on the outer peripheral side of the facility.
Each of the column members 5 is a square tube material whose cross-sectional shape is a square hollow shape, specifically, a square tube obtained by cutting a commercially available square steel pipe by drawing into a suitable length in advance at a factory. It is comprised by the cylinder material and is comprised as an integrated shape which continues along an up-down direction from the upper part side of the floor frame part UK to an upper end part. Each beam member 6 is formed to have a length substantially corresponding to the width in the horizontal direction of each panel P so as to connect the column members 5 in the horizontal direction, and is positioned at each of the intermediate portion in the vertical direction and the upper portion. The beam member 6 is configured by a rectangular tube portion 6a made of a rectangular tube material in which a cross-sectional shape similar to that of the column member 5 has a square hollow shape, and a cross-sectional shape is formed at both ends in the longitudinal direction. It is comprised by the H-shaped part 6b which consists of H-shaped steel materials, and they are comprised by connecting beforehand by welding. In addition, the lower beam member 6 that also serves as a member that supports the floor surface is formed of an H-shaped steel material over the entire region.

As shown in FIG. 9, a vertical connection plate 75 is welded and fixed to the connection portion of the outer peripheral surface of the column member 5 with the beam member 6 so as to protrude laterally. The column member 5 and the beam member 6 are connected by bolting the shape portion 6b and the connecting plate 75. Further, on the outer peripheral surface of the column member 5 constituting the left and right side portions on the inner peripheral surface of the rectangular frame portion, a flange is provided over almost the entire vertical direction of the frame portion in a state protruding toward the inner side of the frame portion. A vertical mounting plate 77 as a part is fixed by welding. The mounting plate 77 is formed with a plurality of bolt insertion holes 78 for panel fastening.

Used. And two frame parts are formed in the vertical direction between adjacent column members 5, and the number of panels that can be mounted side by side in each frame part is higher in the upper one than in the lower one. The panel P is assembled in a state in which the panels P are arranged in the vertical direction.
That is, between the lowermost beam member 6 that also serves as a floor support member and the intermediate beam member 6, three panels P are mounted side by side, and the intermediate beam member 6 and the upper beam member 6 are attached to each other. Between the beam members 6, four panels P are mounted side by side.
Note that FIG. 5 shows a state in which one of the four surrounding surfaces (panel, intermediate column member, etc.) in the side wall portion forming the rectangular storage space in a plan view is cut away.

  The mounting structure of the panel P will be described. As shown in FIG. 10, the mounting plate 71 on the left and right sides of the panel P is applied so as to overlap the mounting plate 77 attached to the column member 5. The panel P is connected and fixed to the column member 5 by tightening with bolts and nuts 79 as screw-type fasteners that are inserted through the plurality of bolt insertion holes 73 and 78 formed respectively. .

Then, inside the storage space, as shown in FIG. 18, between the upper and lower edges of the panel P and the beam member 6 or other panel P as an adjacent object adjacent to the upper and lower edges, they are in the storage space inside and outside. Sealing means S is provided for sealing in a state that allows relative movement.
The sealing means S is in the form of a metal band plate, and has an adhesive portion on both ends in the width direction, and a flexible portion that allows relative movement between the two adhesive portions. The belt-like sheet S is composed of the formed belt-like sheet, and the belt-like sheet S extends between the upper and lower edges of the panel P and the adjacent objects, that is, the other panels P and the beam member 6. It is stuck along the longitudinal direction of the part.
When the explanation is added, the sealing means S is constituted by a thin strip-like seal made of stainless steel, and an adhesive portion t in which an adhesive is applied to both end sides in the width direction is formed on one surface thereof. Between the two sticking parts t and t, for example, as shown in FIG. 19 (a), the sticking parts t and t may move relative to each other by forming a folded part as the accommodation part y. In the configuration in which both the adhering portions t and t are adhered to the upper and lower edge portions of the panel P and the adjacent object along the longitudinal direction of the upper and lower edge portions of the panel P, respectively. It has become. In addition, as the said interchangeable part y, as shown to FIG. 19 (B), the thing of the structure which a cross section bends and forms in corrugated form etc. may be sufficient.

In this way, when grains are stored in the storage space, a load is applied by the stored grains, and even if the panel P bends inward or outward in the storage space, another panel P or beam member 6 is used. While allowing relative movement between the two, it is possible to effectively avoid the occurrence of a gap between them and the entry of grain.
By the way, although the thickness of the beam member 6 is slightly larger than the thickness of the panel P, the corner portion of the beam member is formed in an arc shape as shown in FIG. It is configured to be guided to fall.

  Then, as shown in FIGS. 10 and 21, plate-like partitions that partition the corners of the storage space in the non-reserved state at each of the four corners of the peripheral wall portion formed in a substantially square shape in plan view. The body 97 is provided in a state that extends over the adjacent wall portions and is positioned in the entire height direction of the wall portions. Therefore, the connection part of the panel P and the column member 5 is interrupted | blocked with the storage space, and becomes an area | region where grain does not exist. If the corners at the four corners of such a peripheral wall portion are allowed to store grains in that region, they become unstirred regions by the agitating screw 11 as shown in FIG. By providing 97 and shutting off the storage space, it is possible to prevent grain from being stored in a region where stirring is not performed.

The unstirred zone by the stirring screw 11 is not only a portion corresponding to the corners of the four corners of the peripheral wall portion in a plan view, but also a region where stirring is not performed in the lower corner portion in the side view as shown in FIG. Therefore, as in the case of the vertical partition plate 97, as shown in FIG. 21, the horizontal partition plate 98 in an oblique posture is provided, and the grain is stored in an area that is not agitated by blocking the storage space. To prevent it from happening. The partition plate 98 is formed with a vent hole 98a through which circulated air from the blower 32 flows.
