DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-humidity and low-temperature storage for indirectly cooling a storage room defined inside an insulated box and maintaining the storage room at a high humidity. The present invention relates to a high-humidity and low-temperature storage provided with a drain hole for draining water remaining in a storage.

[0002]

2. Description of the Related Art Conventionally, a high-humidity and low-temperature storage of this type is disclosed in Japanese Patent Application Laid-Open No. 2-272286 (F25D21 / 14) and has a structure shown in FIG. In addition,
In FIG. 10, only the lower part of the high-humidity low-temperature storage is shown. In this figure, a heat conduction box 02 is disposed inside a heat insulating box 01 of a high-humidity and low-temperature storage at a distance from the heat insulating box 01. The heat conduction box 02 is formed of a metal having good heat conductivity, and the inside thereof is a storage room 03. Cooling means (not shown) cools the space between the heat insulating box 01 and the heat conduction box 02, and indirectly cools the storage room 03 via the heat conduction box 02.
An opening 04 for storing and taking out refrigerated material is formed in the front of the storage room 03, and a heat insulating door 06 is openably and closably mounted by a hinge mechanism so as to close the opening 04, and the heat insulating door 06 is closed. Then, the storage room 03 is shut off from the outside air.

[0003] When the refrigerated material is taken out of the storage room 03 and the heat insulation door 06 is opened and closed in order to store the stored material in the storage room 03, the warm air outside the high-humidity low-temperature storage is released.
Flows into. In this way, the warm air that has flowed in by opening and closing the heat insulating door 06 is cooled by the inner surface of the heat conduction box 02 that is at a low temperature while being mixed with the cool air in the storage room 03. During this cooling, a large amount of dew forms on the inner surface of the heat conduction box 02, that is, the inner surface of the storage room 03, and the dew water flows down to the bottom of the storage room 03. In addition, moisture and the like that evaporate from the stored material in the storage room 03 also form dew on the inner surface of the storage room 03. By the way, a drain hole 08 is arranged at the center of the bottom of the storage room 03, and an inclined surface 09 downward from the four sides around the bottom toward the drain hole 08 is provided on the bottom of the storage room 03. Each is formed. Therefore, the dew condensation water flowing down to the bottom of the storage room 03 is guided to the drain hole 08 by the inclined surface 09, and is discharged to the outside of the high-humidity low-temperature storage from the drain hole 08.

[0004]

If the dew water flowing into the bottom of the storage room 03 stays at the bottom of the storage room 03 as it is, it causes the bottom surface of the storage room 03 to be soiled or decomposed to produce an odor. It is necessary to drain the water immediately.
By the way, when the horizontal width of the high-humidity low-temperature storage increases, the distance from the left end or the right end of the bottom surface of the storage room 03 to the drain hole 08 increases. When the height difference between the left end and the right end of the bottom surface of the storage room 03 and the drain hole 08 increases accordingly, the inclination angle of the inclined surface 09 can be maintained at an appropriate value. However, when the positions of the left end and the right end of the bottom surface of the storage room 03 are increased in order to increase the height difference,
There is a problem that the height of the internal space of the storage room 03 is reduced and the capacity of the storage room 03 is reduced. On the other hand, the position of the drain hole 08 cannot be lowered because the distance from the floor surface on which the high-humidity low-temperature storage is placed is not so large. Therefore, the height difference between the left end and the right end of the bottom surface of the storage room 03 and the drainage hole 08 cannot be increased in accordance with the width of the high humidity low temperature storage, so that the inclined surface 09 formed on the bottom surface of the storage room 03 is not formed. The inclination angle becomes smaller. As a result, there is a possibility that the condensed water will not flow to the drain hole 08 but will stay on the way.

The present invention has been made to solve the above-described problems, and provides a high-humidity low-temperature storage in which drainage at the bottom of the storage room is quickly performed even if the width of the high-humidity low-temperature storage increases. The purpose is to:

[0006]

In order to achieve the above-mentioned object, in the high-humidity and low-temperature storage according to the present invention, a heat-insulating box (1) having an opening (2) and an opening / closing door (6, 7) is provided. A heat conduction box (11) is disposed at a distance from the heat insulation box, the interior of the heat conduction box is used as a storage room (12), and the heat insulation box and the heat conduction box are provided. The cooling means (22, 23) for cooling the space between the storage room and the storage room is indirectly cooled. A downwardly inclined surface (31, 32) is formed on the bottom surface of the storage room from the front end portion and the rear end portion toward the center, respectively, and a drain hole (37) is formed at the center of the bottom surface of the storage room. Is provided. Further, a bar (47) is placed on the bottom surface of the storage chamber, and an insertion portion (48) inserted into the drain hole is formed in the bar.

It is preferable that a pair of the bar members (61, 62) be provided, and that the pair of bar members be arranged side by side and joined. Further, the rod may be covered with a porous material (71).

[0008] is et al., There is a case where band-shaped porous compact which extends laterally from the drain hole (91) is disposed on the bottom surface of the storage compartment.

[0009]

[Operation] The cooling means cools the space between the heat insulating box and the heat conduction box, and indirectly cools the storage room. Due to this cooling, excess moisture in the storage chamber is condensed on the inner surface of the heat conduction box and becomes water droplets and flows down to the bottom of the storage chamber. Then, this water is guided by the inclined surface formed on the bottom surface of the storage room, gathers at the central portion of the bottom surface of the storage room, and is guided to a rod or a porous molded body by the action of the surface tension of the water, and the drain hole is formed. Is quickly discharged.

[0010]

Next, a first embodiment of a high-humidity low-temperature storage according to the present invention will be described with reference to FIGS. FIG.
1 is a front view of a first embodiment of a high-humidity low-temperature storage according to the present invention. FIG. 2 is a longitudinal sectional view of FIG. FIG. 3 is a perspective view of the lower part of the high-humidity low-temperature storage. FIG. 4 is a front vertical sectional view of a drain hole. 5A and 5B are diagrams for explaining a rod which is a surface tension action inducing means. FIG. 5A is a cross-sectional view taken along line AA of FIG. 3 and FIG. 5B is a cross-sectional view taken along line BB of FIG.

1 to 3, an insulating box 1 of a high-humidity and low-temperature storage is constructed by filling a heat insulating material between inner and outer boxes, and has an opening 2 for storing and taking out refrigerated material on the front surface thereof.
Are formed. At the center of the opening 2, a vertical middle partition 3 and a horizontal middle partition 4 perpendicular to the vertical middle partition 3 are fixed in a cross shape. In FIG. 3, the vertical middle partition 3 is shown with a lower part cut away. Insulating doors 6 and 7, which are a pair of upper and lower substantially vertical front doors, are openably and closably attached to the insulating box 1 by a hinge mechanism so as to close the opening 2, and the doors 6 and 7 are closed. In the state
The packings 8 and 9 provided around the inner surfaces of the doors 6 and 7 are in close contact with the vertical middle partition 3 and the horizontal middle partition 4 and the like.

Inside the heat-insulating box 1, a heat-conducting box 11 having a front opening is arranged and fixed to all the inner surfaces of the heat-insulating box 1. The heat conduction box 11 is made of a metal having good heat conductivity, for example, stainless steel, and the inside thereof is a storage room 12. A plurality of shelves 13 for placing refrigerated items are mounted in the storage room 12 so that the vertical position thereof can be adjusted.

The space between the heat-insulating box 1 and the heat conduction box 11 serves as a cool air passage 16, and a drain pan 17 is disposed above the cool air passage 16. This drain pan 17
Has an outlet 19 at its front and an inlet 20 at its rear. And drain pan 1
7, an evaporator 22 is housed, and a blower 23 for circulating cool air is provided in front of the evaporator 22.
Are arranged facing the outlet 19. An electric compressor 24, a condenser 25, and a condenser air cooling fan 26 are mounted on the top wall of the heat insulating box 1. The evaporator 22 is connected to the electric compressor 24 and the condenser 25 to form a refrigeration cycle.

The cold air flow passage 16 between the rear wall of the heat conduction box 11 and the rear wall of the heat insulating box 1 is divided forward and backward by a vertically arranged partition plate 27, and is forwardly separated. Is formed with a discharge passage 16a, and a return passage 16b is formed on the rear side. The discharge passage 16a and the return passage 16b communicate with each other through a communication port 28 provided at a lower portion thereof. Then, when the blower 23 is driven, the cool air cooled by the evaporator 22 is discharged from the outlet 19 to the cool air flow path 16, and the discharged cool air is, as shown by an arrow shown in FIG.
The heat conduction box 11 is cooled by passing through the cold air flow path 16 above the top wall of the heat conduction box 11 and then through the discharge passage 16a behind the rear wall of the heat conduction box 11. Then, the cool air that has passed through the discharge passage 16a is supplied to the communication port 28 disposed below the discharge passage 16a.
Then, the water flows into the return passage 16b, flows upward, and returns to the evaporator 22 from the suction port 20. In this way, the cool air cooled by the evaporator 22, the blower 23, and the outlet 19 as the cooling means circulates in the cool air passage 16, thereby cooling the inside of the cool air passage 16. The air is cooled indirectly via the heat conduction box 11.

By indirectly cooling the storage room 12 in this manner, the storage room 12 can be maintained at a high humidity.
By the way, in the case of such a high-humidity low-temperature storage of the indirect cooling system, the humidity caused by warm air entering from the outside of the high-humidity low-temperature storage by opening and closing the doors 6 and 7 and the like, and the storage room 1
Excess water in the storage room 12 such as water evaporating from the refrigerated material in the storage unit 2 forms a large amount of dew on the inner surface of the storage room 12, and the condensed water flows down to the bottom of the storage room 12.

On the bottom surface of the storage room 12, a front inclined surface 31 inclined downward from the front end toward the central portion and a rear inclined surface 32 inclined downward from the rear end to the central portion are formed. The cross section is substantially V-shaped, and a valley 33 extending in the horizontal direction is formed with the boundary between the front inclined surface 31 and the rear inclined surface 32 being the lowest. The shape of this substantially V-shaped cross section is almost unchanged in the lateral direction of the high-humidity low-temperature storage, and the bottom surface of the high-humidity low-temperature storage is inclined in the front-rear direction, but almost inclined in the horizontal direction. It is almost horizontal. An opening 35 is formed in the bottom wall of the heat conduction box 11 that forms the bottom surface of the storage room 12 at substantially the center of the valley 33 as shown in FIGS. The drain pipe 37 is fitted from above the opening 35, and the lower surface of the upper flange portion 38 of the drain pipe 37, which is the drain hole, is in contact with the upper surface of the bottom wall of the heat conduction box 11.

The drain pipe 37 is connected to a socket 41 (see FIG. 2) provided on the bottom of the heat insulating box 1.
The defrost water of the evaporator 22 is received by the drain pan 17, and the defrost water drain pipe 43 connected to the drain pan 17 is provided.
Through the socket 4 to which the defrost water drain pipe 43 is connected
Flow into 1. The drain hose 4 is provided in the socket 41.
The drain hose 45 joins the water flowing into the socket 41 from the drain pipe 37 and the defrost water drain pipe 43 and discharges the high humidity and low temperature storage outside.

As described above, the condensed water that has flowed down from the inner surface of the storage room 12 to the bottom is guided by the front slope 31 and the rear slope 32 and flows into the valley 33. Is almost horizontal in the left-right direction and has no inclination as described above. Therefore, on the bottom surface of the storage room 12, that is, on the upper surface of the bottom wall of the heat conduction box 11, a round bar 47, which is a bar made of metal such as stainless steel or synthetic resin, is mounted. As shown in FIG. 4, the round bar 47 is once bent at a substantially right angle at the center thereof, then bent at approximately 180 °, and further bent at a substantially right angle again. In this manner, a bent portion 48 that is bent in a U-shape, that is, a curved portion, is formed substantially at the center of the round bar 47 in the axial direction. The bent portion 48 is an insertion portion of the round bar 47, and is inserted into a hole of the drain pipe 37. And round bar 47
Are positioned in the valleys 33 on the bottom surface of the storage room 12.

The water remaining in the valleys 33 on the bottom surface of the storage room 12 is gathered by a surface tension in a gap 51 formed between the round bar 47 and the bottom surface of the storage room 12. And
When a certain amount of water gathers and becomes large, the water moves along the round bar 47 which is a means for inducing surface tension action, and the round bar 4
7 and continuously flows down to the drain pipe 37 by being guided by the bent portion 48. In this way, the water in the storage room 12 is drained through the drain pipe 37.

Next, a second embodiment will be described with reference to FIG. FIG. 6 is a sectional view of a main part of the second embodiment corresponding to FIG. 5 of the first embodiment. In the description of the second embodiment, components corresponding to the components of the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted. In the first embodiment, one round bar 47 for inducing the surface tension action is provided, but in the second embodiment, a pair of round bars 61 and 62 are provided. The round bars 61 and 62 are arranged side by side and bound by wires or the like, or joined by soldering, welding, welding, or the like. Like this
By connecting the two round bars 61 and 62 horizontally, a gap 64 between the round bar 61 and the round bar 62 as well as the gap 51 between the bottom wall upper surface of the heat conduction box 11 and the round bars 61 and 62 is formed. Since the surface tension can be used, the water remaining at the bottom of the storage room 12 can be drained more effectively.

As shown in FIG. 4D, the upper surface of the upper flange portion 38 of the drain pipe 37 is
Is arranged so as to be one step lower than the upper surface of the bottom wall of the heat conduction box 11 around the round bar.
The gap between the lower surface of the upper portion 7 and the upper surface of the upper flange portion 38 increases, and the gap 51 shown in FIG. 5B becomes large, so that water may not be efficiently guided to the upper flange portion 38.
On the other hand, in the second embodiment, even when the space between the lower surfaces of the round bars 61 and 62 and the upper surface of the upper flange portion 38 is wide, the gap 51 shown in FIG. The gap 64 between the rods 61 and 62 does not become large and can be maintained substantially as it is. Therefore, drain pipe 3
The water can be efficiently guided to the upper flange portion 38 also at the location of the upper flange portion 38 of FIG.

Next, a third embodiment will be described with reference to FIG. FIG. 7 is a front vertical sectional view of a main part of the third embodiment. In the description of the third embodiment, components corresponding to those of the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted. In the third embodiment, the round bar 47 that induces surface tension is coated with a porous resin,
By inserting the round bar 47 into a porous tube, the surface of the round bar 47 is covered with a porous material having continuous air holes. The covering member 71 made of the porous material having hydrophilicity absorbs the water remaining on the upper surface of the bottom wall of the heat conduction box 11 by surface tension, and guides the water to the bent portion 48 of the round bar 47. Drain to drain pipe 37.

Next, a fourth embodiment will be described with reference to FIG. FIG. 8 is an explanatory view of the drain pipe of the fourth embodiment.
(A) is a perspective view of a drain pipe, (b) is a perspective view of a modification of (a). In the description of the fourth embodiment, the same reference numerals are given to the components corresponding to the components of the first embodiment, and the detailed description thereof will be omitted. In the first embodiment, the upper surface of the upper flange portion 38 of the drain pipe 37 is formed flat. In contrast, FIG.
In the case of the embodiment shown in FIG.
On the upper surface of 8, a groove 81 as a surface tension action inducing means is provided.
It is formed in the radial direction so as to connect the periphery of the upper flange portion 38 and the hole. Further, in the case of the embodiment shown in FIG. 8B, the entire upper surface of the upper flange portion 38 is finished to have a rough surface, so that irregularities 82 as surface tension action inducing means are formed. The unevenness 82 is not necessarily provided on the entire upper surface of the upper flange portion 38, but is preferably arranged so as to connect at least the periphery of the upper flange portion 38 and the hole. As described above, in the fourth embodiment, the groove 81 and the unevenness 82 are formed on the upper surface of the upper flange portion 38. Then, the water guided to the upper surface of the upper flange portion 38 by utilizing the surface tension is guided to the inner surface of the hole of the drain pipe 37 by the grooves 81 and the irregularities 82 formed on the upper surface of the upper flange portion 38. 83 is the drain pipe 3
A male screw portion formed on the outer surface of the socket 7 for connecting the drain pipe 37 to the socket 41.

Further, a fifth embodiment will be described with reference to FIG. FIG. 9 is a longitudinal sectional view of a main part of the fifth embodiment. In the description of the fifth embodiment, components corresponding to the components of the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted. In the first embodiment, a round bar 47 as a surface tension action inducing means is placed on a valley 33 formed on the upper surface of the bottom wall of the heat conduction box 11. However, in the fifth embodiment, an elongated groove 90 is formed in the valley 33 of the heat conduction box 11, and the round bar 47 of the first embodiment is formed.
Instead, a porous formed body 91 which is a band-shaped plate formed of a polymer material is fitted in the groove 90. The porous molded body 91 having continuous ventilation holes as the surface tension action inducing means guides the water flowing down to the valley portion 33 of the heat conduction box 11 to the drain pipe 37 by surface tension, and through the drain pipe 37. Drained outside high humidity low temperature storage.

As described above, in the embodiment, the bottom wall of the heat conduction box 11 is formed by bending a flat metal plate such as stainless steel at the center to form the front inclined surface 31 and the rear inclined surface 32. In addition, since it is formed substantially horizontally in the left-right direction, that is, in the lateral direction, and is not inclined, simple sheet metal processing for bending the plate once is performed. In contrast, FIG.
In the bottom wall of the conventional heat conduction box 02 shown in FIG. 0, an inclined surface 09 is formed from front and rear and right and left toward the drain hole 08, and it is necessary to perform a complicated three-dimensional bending process.
Therefore, in the case of this embodiment, processing is easier than in the conventional case. Also, if the width of the high humidity low temperature storage is different, the conventional high humidity low temperature storage
Although it is necessary to manufacture the bottom wall of the heat conduction box 02, in the case of this embodiment, it can be dealt with only by cutting according to the width of the high-humidity low-temperature storage.

When the width of the high-humidity low-temperature storage is increased, the inclination angle of the left and right inclined surfaces 09 toward the drain hole 08 in the conventional storage room 03 shown in FIG. 10 is reduced, and the drainage efficiency is reduced. On the other hand, in the embodiment, the inclination angles of the front inclined surface 31 and the rear inclined surface 32 are constant irrespective of the width of the high-humidity low-temperature storage, and the water flows toward the valley 33 on the bottom surface of the storage room 12. It is guided at a constant efficiency regardless of the width of the high humidity low temperature storage. Then, the material is promptly guided to a drain hole by a round bar, a porous molded body or the like which is a surface tension action inducing means, and is drained out of the high humidity low temperature storage.

Further, in the case of the embodiment, the front inclined surface 3
Since the trough 33 formed at the boundary between the first and rear inclined surfaces 32 extends in the left-right direction, when the round bar 47 is placed on the bottom surface of the storage room 12, the round bar 47 moves to the trough 33. Thus, the round bar 47 is not inadvertently displaced.

The valley 33 of the storage room 12 is
Is formed substantially in the middle in the front-rear direction of the bottom surface of the bottom surface, so that the inclination angle of the front inclined surface 31 and the inclination angle of the rear inclined surface 32 are substantially equal, and the valley portion 33 is arranged biased forward or rearward. In this case, the inclination angle of one of the front inclined surface 31 and the rear inclined surface 32 does not become small. As a result, the water flowing down to the bottom of the storage room 12 is efficiently collected in the valley 33 on the bottom surface of the storage room 12.

The bent portion 48 of the round bar 47 is formed in a substantially U-shape and has no sharp portion such as a cut surface of the round bar 47. Therefore, when the bent portion 48 is inserted into the hole of the drain pipe 37, There is little risk of damaging the bottom surface of the storage room 12 and the like. Further, the round bars 47, 61, 62 and the porous molded body 91 are provided in the storage room 12
It can be easily attached and detached because it is only placed on the bottom of the. As a result, the bottom surface of the storage room 12 can be easily cleaned. Further, when the surface tension action inducing means is placed on the bottom surface of the storage room 12 and the surface tension action inducing means is too flexible like a cloth, it is necessary to place both ends thereof at a predetermined position. In the case of a rod such as the round bar 47, the rod has appropriate rigidity, and can be easily placed on the bottom surface of the storage room 12 with one hand.

Further, the bent portion 48 is formed at the center of the round bar in the axial direction. Since the bar projects substantially horizontally from the bent portion 48 to the left and right sides, only one side of the bottom of the storage chamber 12 is provided. Instead, drainage on both the left and right sides can be performed smoothly. As a result, the mounting of the round bar becomes simpler and the number of members can be reduced as compared with the case where one round bar as the surface tension action inducing means is separately arranged on each of the left and right sides of the bottom surface of the storage chamber 12.

Although the embodiments of the present invention have been described in detail, the present invention is not limited to the above-described embodiments, and various modifications may be made within the scope of the present invention described in the appended claims. It is possible to make changes. Modified embodiments of the present invention will be exemplified below. (1) In the embodiment, the bent portion 48 is formed in the middle of the round bar 47, but can be provided at an arbitrary position in the center of the round bar 47. (2) In the embodiment, the bar, which is the surface tension action inducing means, has a circular cross section, but forms a gap with the bottom surface of the storage chamber 12, and water is applied by utilizing the surface tension in the gap. If it can be guided, the cross-sectional shape can be appropriately changed, for example, a semicircle, an ellipse, a pentagon, a polygon, and the like.
Also, it is possible to form irregularities on the surface of the bar.

(3) In the embodiment, the bottom surface of the storage room 12 is inclined only in the front-rear direction, but it can also be inclined in the front-rear direction and the left-right direction as in the conventional example shown in FIG. . When the surface tension action inducing means is mounted on the bottom surface of the storage room 12 which is inclined only forward and backward and not inclined in the horizontal direction as in the embodiment, the drainage efficiency changes depending on the width of the high humidity low temperature storage. It's the best to do. (4) In the fourth embodiment, only one of the groove 81 and the unevenness 82 is formed on the upper surface of the upper flange portion 38 of the drain pipe 37, but both may be formed. (5) In the fifth embodiment, the porous molded body 9 having hydrophilicity
1 has a plate shape, but its cross-sectional shape can be changed as appropriate, and for example, it can be a column shape.

[0034]

According to the present invention, a bar or a porous molded body is placed on the bottom surface of a storage room of a high-humidity low-temperature storage room. Even in the case where there is almost no water, the water that has been guided to the rod or the porous molded body and collected at the center of the bottom surface of the storage chamber can be quickly discharged to the drain hole by the action of the surface tension of the water. In addition, since the insertion portion inserted into the drain hole is formed in the rod, the rod is positioned in the drain hole, and water is guided into the drain hole by the insertion portion of the rod.

In the case where the bars are connected side by side in a pair, even if the bars and the mounting surface on which the bars are placed are separated from each other and the interval is widened, the bars are not connected to each other. Since the gap is maintained substantially as it is, the surface tension caused by this gap can be used.
Therefore, even when there is a variation in the gap between the bar and the mounting surface, the water can be drained in a stable state.

[0036] Then, when the bar is coated with a porous material, since this porous material absorbs water by the action of surface tension, Ru can be drained more quickly.
