Description

The present invention relates to an air circulation type processing device such as a constant temperature bath, a constant temperature and humidity chamber, and a cooker.

Conventionally, an air circulation type processing device used for applications such as a constant temperature bath, a constant temperature and humidity chamber, and a cooker is known.

For example, Patent Document 1 discloses a constant temperature chamber that can maintain a processing chamber at a predetermined temperature without complicating the structure. In this constant temperature chamber, a plurality of circulating air suction ports are formed behind the shelf for placing articles in the partition plate that separates the duct and the processing chamber. These circulating air suction ports are formed so as to increase toward the bottom of the partition plate. Since Patent Document 1 has the above-mentioned structure, it is possible to positively circulate the circulating air to the lower part of the processing chamber, so that the air in the processing chamber can be circulated more evenly. It is stated that it will be possible.

Patent Document 2 discloses an air conditioner including a plurality of guide members fixed at positions corresponding to a plurality of horizontal support plates. In this air conditioner, the length of the protruding portion is longer toward the lower guide member, so it is possible to adjust the flow of air flowing into the processing chamber and supply the air to the vicinity of the sample (object to be processed). It will be possible.

By the way, a constant temperature chamber as shown in FIG. 2 of Patent Document 1, that is, a plurality of horizontal shelves (support plates) are arranged in the vertical direction, and the air outlet is above these support plates. The following air flow is likely to be formed in a thermostatic chamber located at a position and at a position shifted horizontally from the support plate. That is, the air blown downward from this air outlet tends to flow along the inner surface (wall surface) of the processing chamber. For this reason, the air blown downward hardly flows into the space between the uppermost support plate and the partition plate above it, and tends to flow unevenly between the lower support plates. As a result, the flow rate and wind speed distribution of the air flowing into the plurality of support plates (plurality of stages) are likely to be biased.

Therefore, when the circulating air suction port is formed so as to increase downward in the partition plate as in the constant temperature chamber of Patent Document 1, the tendency that the air flows unevenly between the lower support plates becomes more remarkable. Is thought to be.

Moreover, in the thermostatic chamber of Patent Document 1, since the object to be processed can be arranged at an arbitrary position on the support plate, the position on the support plate on which the object to be processed is arranged varies, so that the object to be processed is processed. The degree of processing of objects may also vary. Regarding this point, even if the guide member is provided as in the air conditioner in FIG. 4 of Patent Document 2, the object to be processed can be arranged at an arbitrary position on the support plate.

An object of the present invention is that in an air circulation type processing apparatus that thermally treats a plurality of objects to be processed in a processing chamber, the degree of processing of a plurality of objects to be processed set in a plurality of stages varies. It is to suppress.

The first processing apparatus of the present invention has a processing chamber for thermally treating a plurality of objects to be processed, and while blowing air-conditioned air into the processing chamber through a blowing portion provided in the processing chamber, the processing. It is an air circulation type processing device that sucks out the air in the processing chamber through a suction unit provided in the chamber. The first processing apparatus corresponds to each of the plurality of support members that support the plurality of objects to be processed in the processing chamber and the plurality of support members at intervals in the vertical direction. A positioning unit for positioning an object to be processed is provided. The blowing portion is provided at a position biased in the first direction parallel to the central portion of the processing chamber in the first direction and is provided in the upper part of the processing chamber, and the conditioned air is supplied to the plurality of objects to be processed. It is configured to blow out from the top to the bottom. The suction portion is located at a position biased in a second direction opposite to the first direction with respect to the central portion of the processing chamber, and is lower than the lowest support member among the plurality of support members. It is provided at a position diagonal to the blowout portion. Each of the plurality of objects to be treated has a first end portion in the first direction. The positioning portion is located at a position where the first end portion of at least the uppermost object to be processed among the plurality of objects to be processed overlaps the blowout portion in a plan view, and the lower object to be processed is said to be said. The plurality of objects to be processed are positioned so that the first end portion is located at a position biased in the first direction with respect to the central portion.

As described above, since the first processing device includes a positioning unit for positioning the corresponding object to be processed with respect to each of the plurality of support members, the plurality of objects to be processed are set at predetermined positions. Will be.

Moreover, the positioning unit positions the plurality of objects to be processed so that the first end portion of at least the highest object to be processed among the plurality of objects to be processed is located at a position overlapping the blowout portion in a plan view. Therefore, a part of the conditioned air blown downward from the blowout portion surely flows toward the first end portion of the uppermost object to be processed. Since the suction portion is provided at a position biased in the second direction opposite to the first direction with respect to the central portion of the processing chamber, the suction portion is provided on the upper surface in the vicinity of the first end portion in the highest object to be processed. The arriving air flows in the second direction along the object to be processed in the processing chamber.

Further, the positioning portion has a plurality of objects to be processed so that the lower object to be processed (the object to be processed farther from the blowout portion) has the first end portion biased in the first direction with respect to the central portion. Position an object. Therefore, in the object to be processed below the uppermost object to be processed, the first end portion of the other object to be processed does not exist directly above each first end portion. Therefore, the remaining conditioned air that has been blown out from the blowout portion and has passed downward beside the top object to be treated flows toward the first end portion of the object to be treated that is below the top object to be treated. The air that has reached the upper surface near the first end flows in the second direction along the object to be processed. In this way, an air flow in the second direction can be formed along each of the plurality of objects to be processed.

Therefore, in the first processing device, unlike the conventional processing device, the air blown downward from the blowing portion hardly flows into the space between the uppermost support plate and the partition plate above it, and the lower portion It is possible to solve the problem of uneven flow into the support plate. Moreover, as described above, the positioning unit sets a plurality of objects to be processed at predetermined positions. Therefore, it is possible to prevent variations in the degree of processing of the plurality of objects to be processed set in the plurality of stages. Therefore, the user (worker) does not need to pay attention to the arrangement position of the object to be processed.

The second processing apparatus of the present invention has a processing chamber for thermally treating a plurality of objects to be processed, and while blowing conditioned air into the processing chamber through a blowing portion provided in the processing chamber, the processing. It is an air circulation type processing device that sucks out the air in the processing chamber through a suction unit provided in the chamber. The second processing apparatus corresponds to each of the plurality of support members that support the plurality of objects to be processed in the processing chamber and the plurality of support members at intervals in the vertical direction. A positioning unit for positioning an object to be processed is provided. The blowing portion is provided at a position biased in the first direction parallel to the central portion of the processing chamber in the first direction and at the lower part of the processing chamber, and the conditioned air is supplied to the plurality of objects to be processed. It is configured to blow upward from the bottom. The suction portion is located at a position biased in a second direction opposite to the first direction with respect to the central portion of the processing chamber and above the uppermost support member among the plurality of support members. It is provided at a position diagonal to the blowout portion. Each of the plurality of objects to be treated has a first end portion in the first direction. The positioning portion is located at a position where the first end portion of at least the second object to be processed from the bottom of the plurality of objects to be processed overlaps the blowout portion in a plan view, and the object to be processed is on the upper side. The plurality of objects to be processed are positioned so that the first end portion is located at a position biased in the first direction with respect to the central portion.

As described above, since the second processing device includes a positioning unit for positioning the corresponding object to be processed with respect to each of the plurality of support members, the plurality of objects to be processed are set at predetermined positions. Will be.

Moreover, the positioning unit positions the plurality of objects to be processed so that the first end portion of at least the second object to be processed from the bottom of the plurality of objects to be processed overlaps with the blowout portion in a plan view. To do. Therefore, a part of the conditioned air blown upward from the blown portion surely flows toward the second object to be processed. Since the suction portion is provided at a position biased in the second direction opposite to the first direction with respect to the central portion of the processing chamber, the air reaching the lower surface of the second object to be processed can be removed. In the processing chamber, the space between the second object to be processed and the lowest object to be processed flows in the second direction along the object to be processed. Therefore, the bottom object to be treated can be effectively heat-treated.

Further, the positioning portion has a plurality of objects to be processed so that the upper object to be processed (the object to be processed farther from the blowout portion) has the first end portion biased in the first direction with respect to the central portion. To position. Therefore, in the object to be processed above the lowest object to be processed, the first end portion of the other object to be processed does not exist directly below each first end portion. Therefore, the remaining conditioned air that has been blown out from the blowout portion and has passed upward by the side of the second object to be processed flows toward the first end portion of the object to be processed above it, and the first end thereof. The air that has reached the lower surface in the vicinity of the portion flows in the space between the object to be processed and the object to be processed below it in the second direction. In this way, an air flow in the second direction can be formed along each of the plurality of objects to be processed.

Accordingly, in the second processing unit, flowing mostly into the space between the air blown to the upper direction from the blowout portion as in the conventional processing apparatus from below the second support plate and the support plate beneath the It is possible to solve the problem of uneven flow into the upper support plate without the problem. Moreover, as described above, the positioning unit sets a plurality of objects to be processed at predetermined positions. Therefore, it is possible to prevent variations in the degree of processing of the plurality of objects to be processed set in the plurality of stages. Therefore, the user (worker) does not need to pay attention to the arrangement position of the object to be processed.

In the processing apparatus, each of the plurality of objects to be processed has a second end portion in the second direction, and the positioning portion is such that the object to be processed closer to the blowout portion has the second end portion. It is preferable that the plurality of objects to be processed are positioned so as to be positioned at a position biased in the second direction with respect to the central portion.

As described above, not only the object to be processed farther from the blowout portion has the first end portion biased in the first direction, but also in this configuration, the object to be processed closer to the blowout portion has the second end portion second. The position is biased in two directions. As a result, when comparing the flow paths of air flowing along each of the plurality of objects to be processed, the difference in pressure loss in these flow paths can be reduced. As a result, it is possible to further suppress the occurrence of bias in the flow rate and wind speed of the air flowing in the plurality of stages.
Further, the third processing apparatus of the present invention has a processing chamber for thermally treating a plurality of objects to be processed, and blows air-conditioned air into the processing chamber through a blowing portion provided in the processing chamber. An air circulation type processing device that sucks out air in the processing chamber through a suction unit provided in the processing chamber, and supports the plurality of objects to be processed in the processing chamber at intervals in the vertical direction. A plurality of support members and a positioning portion for positioning a corresponding object to be processed are provided for each of the plurality of support members, and the blowout portion is parallel to the central portion of the processing chamber in the horizontal direction. It is provided at a position biased in the first direction, and is configured to blow out the air-conditioned air downward from above the plurality of objects to be processed, and the suction portion is located in the central portion of the processing chamber. On the other hand, the positioning portion is provided at a position biased in the second direction opposite to the first direction, and the positioning portion is separated from the inner surface on the suction side, which is the inner surface on the suction portion side in the processing chamber, in the first direction. Each of the plurality of objects to be processed has a first end portion in the first direction and a second end portion in the second direction, and the positioning portion includes the plurality of positioning portions. The first end portion of at least the uppermost object to be processed is located at a position overlapping the blowout portion in a plan view, and the lower the object to be processed, the more the first end portion is the central portion. The plurality of objects to be processed are positioned so as to be biased toward the first direction, and the closer the object to be processed is to the blowout portion, the closer the second end portion is to the central portion. The plurality of objects to be processed are positioned so as to be located at a position biased in the second direction and close to the inner surface on the suction side.
Further, the fourth processing apparatus of the present invention has a processing chamber for thermally treating a plurality of objects to be processed, and blows air-conditioned air into the processing chamber through a blowing portion provided in the processing chamber. An air circulation type processing device that sucks out air in the processing chamber through a suction unit provided in the processing chamber, and supports the plurality of objects to be processed in the processing chamber at intervals in the vertical direction. A plurality of support members and a positioning portion for positioning a corresponding object to be processed are provided for each of the plurality of support members, and the blowout portion is parallel to the central portion of the processing chamber in the horizontal direction. It is provided at a position biased in the first direction, and is configured to blow out the air-conditioned air upward from below the plurality of objects to be processed, and the suction portion is located in the central portion of the processing chamber. On the other hand, the positioning portion is provided at a position biased in the second direction opposite to the first direction, and the positioning portion is separated from the inner surface on the suction side, which is the inner surface on the suction portion side in the processing chamber, in the first direction. Each of the plurality of objects to be processed has a first end portion in the first direction and a second end portion in the second direction, and the positioning portion includes the plurality of positioning portions. The first end portion of at least the second object to be processed from the bottom of the object to be processed is located at a position overlapping the blowout portion in a plan view, and the upper object to be processed has the first end portion. The plurality of objects to be processed are positioned so as to be biased in the first direction with respect to the central portion, and the object to be processed closer to the blowout portion has the second end portion closer to the central portion. On the other hand, the plurality of objects to be processed are positioned so as to be in a position biased in the second direction and close to the inner surface on the suction side.

In the processing apparatus, the positioning portion has a plurality of contact portions for positioning the plurality of objects to be processed, and the plurality of contact portions have the corresponding objects to be processed along the horizontal direction in the processing chamber. It is preferable that the corresponding object to be processed is positioned so as to be in contact with the corresponding object to be processed when the object is inserted.

In this configuration, since the positioning portion has a plurality of contact portions as described above, it is only necessary to insert the corresponding object to be processed into the processing chamber along the horizontal direction and bring it into contact with the contact portion. An object can be positioned at a predetermined position. Thereby, a plurality of objects to be processed can be arranged at a desired position, that is, at a position where the plurality of objects to be processed are displaced from each other by a simple operation.

In the processing apparatus, the positioning unit determines the amount of deviation in the first direction between the first end portion of each of the plurality of objects to be processed and the first end portion of the object to be processed adjacent thereto. It is preferable that the plurality of objects to be processed are positioned so that the magnitudes of these deviations are the same when compared.

In this configuration, since the magnitude of the deviation in the first direction in the adjacent objects to be processed is the same, the area of the displaced portion is the same in each object to be processed. Therefore, since the area of the portion that can receive the air flowing downward or upward is the same size, it is possible to reduce the variation in the flow rate of the air along the plurality of objects to be processed.

In the processing apparatus, the positioning unit determines the amount of deviation in the first direction between the first end portion of each of the plurality of objects to be processed and the first end portion of the object to be processed adjacent thereto. When compared, the plurality of objects to be processed may be positioned so that the size of the deviation becomes larger as the object to be processed is farther from the blowout portion.

This configuration is suitable for, for example, a case where the flow rate and wind speed of the air blown from the blowing portion become smaller as the distance from the blowing portion increases. Specifically, in this configuration, the larger the object to be processed is farther from the blowout portion, the larger the magnitude of the deviation. Therefore, the area of the displaced portion is larger as the object to be processed is farther from the blowout portion. Therefore, in the object to be processed far from the blowout portion, even if the flow rate or wind speed of the air flowing in the vicinity thereof is small, the area of the displaced portion is relatively large, so that the displaced area is relatively large as compared with the case where the displaced area is the same. You can receive a lot of air in the part. Thereby, even in the above-mentioned case, the variation in the flow rate of the air along the plurality of objects to be processed can be reduced.

In the processing device, it is preferable that the blowing portion has a guide portion for guiding the blowing direction of the conditioned air so as to approach the vertical direction.

In this configuration, the guide portion brings the air blowing direction closer to the vertical direction, so that the flow of air blown from the blowing portion becomes more stable. As a result, it is possible to prevent variations in the flow rate of air distributed to the plurality of stages due to the turbulence of the air flow.

In the processing apparatus, each support member is configured to support both sides of the object to be processed extending from the first end portion of the corresponding object to be processed along the second direction. When the conditioned air blown from the blowing portion into the processing chamber flows in the second direction along the object to be processed in a state of supporting the object, it is a pair of inner surfaces of the processing chamber. It is preferably configured to prevent passing between the pair of inner surfaces of the object to be treated facing each other and the sides of the object to be treated.

In this configuration, when the conditioned air blown from the blowout portion into the treatment chamber flows in the second direction along the object to be processed, it passes between both sides of the object to be processed and the pair of inner surfaces. Stop. As a result, most of the air flowing along the object to be processed flows from the first end portion in the second direction along the object to be processed without flowing downward or upward from both sides of the object to be processed. Reach the second end of. Therefore, the flow of air along the object to be processed from the first end to the second end of the object to be processed is more stable, so that the flow rate of air flowing to the plurality of stages in which the plurality of objects to be processed are set can be increased. It is possible to further suppress the occurrence of bias in the wind speed.

According to the present invention, in an air circulation type processing apparatus that thermally treats a plurality of objects to be processed in a processing chamber, the degree of processing of a plurality of objects to be processed set in a plurality of stages varies. It can be suppressed.

FIG. 13 is a schematic view for explaining the flow of air in the processing device 1 shown in FIG.

As shown in FIGS. 7, 11, 12 (A) and 12 (B), the blowout portion 20 includes a plurality of guide portions 24 (guide vanes 24) and these guide portions 24 as the main body of the housing 4. It has mounting members 22 and 23 to be attached to 4A. The guide unit 24 is for guiding the flow of air blown into the processing chamber 2 downward. The number of guide portions 24 may be one instead of plural.

The mounting members 22 and 23 are mounted on a pair of inner surfaces of the main body 4A of the housing 4 facing the third direction D3 by fixing members such as bolts. Both ends of the plurality of guide portions 24 are fixed to the mounting members 22 and 23 in a state of being bridged between the mounting members 22 and 23, respectively. The three guide portions 24, excluding the guide portion 24 on the door 4B side, have an L-shape in the side view shown in FIG. 7. As shown in FIG. 7, the guide portion 24 closest to the door 4B has a flat plate shape that is not bent in an L shape.

The guide portion 24 shown in FIG. 11 is a plate-shaped member extending along the third direction D3. Adjacent guide portions 24 are arranged at intervals in the vertical direction V and the horizontal direction (first direction D1). The air outlet 21 is formed by the gap between the adjacent guide portions 24 formed thereby. In FIG. 11, the guide portion 24 closest to the door 4B is not shown.

As shown in FIG. 7, each guide portion 24 having an L-shaped cross section has a horizontal portion 24A located on the upstream side of the air flow and an end portion of the horizontal portion 24A, as shown in FIG. 12 (B).

The space between and) flows.

In this processing device 1, as shown in FIG. 13, the conditioned air blown downward from the ceiling surface 15 flows downward along the inner surface 11 of the door 4B, and is gradually divided into each stage. That is, a part of the downward flow of the air blown out from the blowing portion 20 near the object to be processed M1 in the uppermost stage is divided into the uppermost stage, and the rest is gradually divided from the second stage to the lowermost stage. It will be. As a result, almost uniform air is diverted in all stages, and a good temperature / humidity distribution can be obtained.

As a means for suppressing unevenness in the flow rate of air flowing into a plurality of stages and the wind speed of air, for example, a plate-shaped support member having good air permeability (net-like support member) can be considered. When the object to be processed is not breathable like the above-mentioned flat plate for cooking, the ventilation holes provided in the support member are blocked by the object to be processed. On the other hand, in the processing device 1 according to the first and second embodiments described above, when the support member has, for example, a non-breathable shelf board structure, or when the object to be processed has a dish structure such as hotel bread and is not breathable. Even so, a good temperature and humidity distribution can be obtained in all stages.
