Description

  The present invention relates to a storage device that can refrigerate foods and beverages.

As a refrigerated storage device (refrigerated showcase device), a storage room for storing objects to be refrigerated (foodstuffs, beverages packed in cans, bottles, plastic bottles, etc.), and this storage room And a cooling unit for supplying cold air to the battery are known. Patent Document 1 discloses a showcase device that includes a Peltier element and that keeps foods warm or cold.
Japanese Patent Application Laid-Open No. 2000-139631

  As a refrigerated storage device (refrigerated showcase device), a ventilation path arranged to blow out the air (cold air) cooled by the cooling unit into the storage chamber is formed, and the heat absorption part of the cooling unit and the ventilation In order to increase the efficiency of heat exchange with the air flowing through the path, there is known a structure in which fins that are thermally connected to the heat absorbing portion of the cooling unit are exposed to the air blowing path. In such a storage device, since the heat exchange area between the heat absorption part of the cooling unit and the air flowing through the air blowing path can be increased, it is possible to supply cool air to the storage room satisfactorily through the air blowing path. .

  By the way, in such a storage device, when air having a large temperature difference from the fin flows into the blowing path, that is, when air with high relative humidity flows into the blowing path, the air is rapidly cooled by the fins, Condensation may cause the drain to accumulate on the fins and become clogged. If drain accumulates in the fins and becomes clogged, the pressure loss increases and the contact area decreases. As described above, when drain is collected in the fin, the heat exchange efficiency of the cooling unit is lowered. Therefore, it is not preferable that the drain is collected in the fin.

  In order to suppress the accumulation of drain on the fins, for example, it is conceivable to increase the gap between the fins so that the drain is easily dropped as a droplet by its own weight. However, when the gap between the fins is increased, the contact area is reduced and the heat exchange efficiency is lowered. If the contact area is to be secured, the cooling unit becomes large, and the storage device is likely to be enlarged. Therefore, in the case of a relatively small storage device, such as a storage device suitable for installation on a shelf such as a convenience store, it is difficult to increase the gap between the fins, especially when drainage occurs. Cooling efficiency is likely to decrease.

  One aspect of the present invention includes a storage chamber for storing an object to be refrigerated, a cooling unit for supplying cold air into the storage chamber, and a first path arranged to blow cool air into the storage chamber. A storage device. In this storage device, the cooling unit includes a first fin that is exposed to the first path. The storage device further includes a water absorbing member capable of absorbing drain from the first fin and extending along at least a part of the first path.

  According to this storage device, even if air having a relatively large temperature difference from the first fin flows into the first path, i.e., air having a high relative humidity, and drainage occurs in the first fin, This drain can be absorbed by the water absorbing member. Therefore, even if the drain is generated in the first fin, the drain is not accumulated in the fin and clogged, and the heat exchange efficiency can be kept good.

  Further, according to this storage device, since the water absorbing member extends along at least a part of the first path, the drain sucked by the water absorbing member is caused by capillary action (capillary phenomenon, surface tension of water). It can be moved in a direction along at least a part of the first path via the water absorbing member. Therefore, even if drain is further generated in the first fin, the drain can be sequentially moved in a direction along at least a part of the first path.

  In addition, according to this storage device, as described above, the water absorbing member extending along at least a part of the first path causes the drain generated in the first fin to flow through at least one of the first path by capillary action. Move in the direction along the part. For this reason, even if a fin having a relatively small interval is used as the first fin, the first fin is not easily clogged by the drain. Furthermore, the heat exchange efficiency can always be kept good only by providing the water absorbing member so as to extend along at least a part of the first path. For this reason, it is possible to prevent a decrease in heat exchange efficiency with a simple configuration. Therefore, a cooling unit that is compact and has high heat exchange efficiency can be adopted, and the storage device can be downsized.

  The storage device according to one embodiment of the present invention may be applied to a so-called open type storage device in which a part of the storage chamber is opened as an outlet. In addition, the storage device according to one aspect of the present invention normally closes the outlet with a door, opens the door only when taking out the product or replenishing the product, and at least partially removes the outlet. It may be applied to a so-called closed type (closed type) storage device that is opened.

  Furthermore, the storage device according to one aspect of the present invention is applied to an all-fresh storage device for refrigeration that cools air sucked from the outside (fresh air) by a cooling unit and supplies cold air to the storage chamber. Also good. Further, the storage device according to one aspect of the present invention has a first path arranged so as to suck in the air in the storage chamber from one end side and blow cold air from the other end side into the storage chamber, You may apply to the storage apparatus for the refrigerator of the type which circulates air between 1st paths.

  The storage device according to one aspect of the present invention is a closed-type storage device that can open and close in particular, and the first path sucks air in the storage chamber from one end side and stores from the other end side. It is suitable for a storage device arranged to blow cold air into the room.

  That is, in the storage device as described above, when the storage chamber is closed, the temperature of the storage chamber is relatively low even if the temperature of the first fin is relatively low. The temperature difference (Δt) with the first fin is also relatively small. Therefore, in this state, the amount of drain generated is small. On the other hand, when the storage chamber is opened for the purpose of taking out an object to be refrigerated or replenishing goods, the relatively high temperature air (temperature in the storage chamber) enters the first path from the outside through the storage chamber. Hotter air). When such air is cooled and the temperature is lowered, the relative humidity is rapidly increased. Therefore, dew condensation occurs near the first fin, and a large amount of drainage is generated. The storage device according to one embodiment of the present invention can be quickly removed from the first fin even when a large amount of drain is generated, so that a reduction in heat exchange efficiency can be prevented.

  Further, in the storage device according to one aspect of the present invention, the first path has a portion extending vertically, and the first fin and the water absorbing member are disposed in the portion extending vertically. In this case, the water absorbing member is preferably provided so as to extend below the first fin. By doing in this way, since the drain hangs down as a droplet from the lower end of the water absorbing member, the drain absorbed by the water absorbing member is easily collected and discharged.

  In this case, it is preferable to provide means for receiving a drain, for example, a drain pan, a drain tank, etc. below the water absorbing member. By doing so, it is possible to receive (accumulate) the drain dripped downward as a droplet from the water absorbing member.

  Furthermore, as a storage device according to one embodiment of the present invention, a cooling unit including a Peltier element can be employed. In this case, the apparatus can be easily downsized as compared with a storage apparatus including a cooling unit that supplies cold air to the storage chamber using a compressor or the like.

  In the storage device according to one embodiment of the present invention, the shape of the first fin is arbitrary, but as the first fin, for example, a plate fin or a pin fin can be used.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

  The storage device 1 of this example is designed to have a size and weight that can be installed on a shelf called a gondola (a shelf on which products are displayed at room temperature) at a convenience store. This storage device 1 is a storage device for refrigeration (refrigeration showcase device), and functions as a refrigeration device for refrigeration of products (objects) such as food and beverage cans, and as a showcase for displaying products. Combined with the functions.

  The storage device 1 is detachable from a showcase unit 10 including a storage room (display room) 11 for storing an object to be refrigerated (food or beverage in this example) and an outlet 12 of the storage room 11. The door unit 30 is attached to the storage chamber 11, and four cooling units 50 for supplying cold air into the storage chamber 11 are provided.

  The showcase unit 10 has a housing 20 that defines its appearance. Specifically, the housing 20 includes a transparent canopy (ceiling) 21 that covers the upper portion of the storage chamber 11, an opaque upper wall 22 connected to the rear end of the canopy 21, both side walls 23 and 24 of the storage chamber 11, It has a rear wall 25 and a lower wall 26 and is formed in a horizontally long shape. As the transparent canopy 21, a wall body of a hollow double acrylic structure that is lightweight, strong, and has high heat insulation performance is adopted. The transparent canopy 21 is formed such that the upper wall portion 21 a is substantially flat, the front portion 21 b is curved downward, and the tip 21 c is the upper end of the outlet 12.

  In the showcase unit 10, the front inside the housing 20 is a horizontally long storage chamber 11, and the rear is an air conditioning chamber (machine room) 40 including a cooling unit 50. Inside the storage chamber 11, first and second display shelves 27 and 28 are arranged. The second display shelf 28 also serves as the bottom (floor) of the storage chamber 11, and a part of the front of the housing 20 is opened to serve as a product outlet 12.

  The door unit 30 includes a frame member 31 formed in a shape corresponding to the outlet 12, and two door members 32 a and 32 b supported so as to move with respect to the frame member 31. It is assembled so that it can be attached to and detached from the outlet 12. In this example, the two door members 32 a and 32 b slide (slide) with respect to the frame member 31.

  As shown in FIG. 1, in a state where the door unit 30 is attached to the outlet 12 of the showcase unit 10, a part of the outlet 12 is obtained by sliding the door member 32 a and / or 32 b with respect to the frame member 31. Is opened and closed. In this case, the storage device 1 can be used like a so-called closed type storage device in which the storage chamber 11 can be opened and closed. On the other hand, as shown in FIG. 2, the door unit 30 can be integrally removed from the outlet 12 of the showcase unit 10. In this case, the storage device 1 can be used like a so-called open type storage device. In addition, the door member of the door unit 30 should just move with respect to the frame member 31, and may open a part of the storage chamber 11. FIG. Moreover, the number of door members with which the door unit 30 is provided may be one, and may be three or more.

  As shown in FIG. 3, the first path arranged to supply (blow out) the air (cold air) cooled by the cooling unit 50 into the storage chamber 11 inside the housing 20 of the showcase unit 10. (Blower duct, fan space, fan path) 13 is provided. The first path 13 includes a first portion 13a extending in the front-rear direction and a second portion 13b extending in the up-down direction, and has a substantially L-shaped cross section.

  In this example, the air flow path 13 draws in the air in the storage chamber 11 from one end side (the inlet side of the first portion 13a) 13c, and the storage chamber from the other end side (the outlet side of the second portion 13b) 13d. Cold air is blown into 11 and an air curtain is formed at the outlet 12. The 1st part 13a of the ventilation path 13 is arrange | positioned under the storage chamber 11, and is extended in the front-back direction. The first portion 13a of the air passage 13 is for sucking air inside the storage chamber 11 from a plurality of first openings 16 formed at the lower end of the outlet 12 (below the front end of the storage chamber 11). Is. The 2nd part 13b of the ventilation path 13 is arrange | positioned at the back of the storage chamber 11, and is extended in the up-down direction. The second portion 13b of the air blowing path 13 blows out air (cold air) cooled from a plurality of second openings 17 formed on the upper rear side of the storage chamber 11 (the rear side of the upper end portion of the storage chamber 11). Thus, the storage chamber 11 is cooled and an air curtain is formed at the outlet 12. In the above-described transparent ceiling (roof) 21, the front end portion 21 c of the front portion constitutes the upper end of the outlet 12, and guides the light in the store room to the inside of the storage room 11 to make the product easy to see and store. It functions to guide the air flow between the plurality of outlets 17 provided above the chamber 11 and the outlet 12 and form an air curtain at the outlet 12.

  Below the first portion 13a of the air passage 13 and behind the second portion 13b are configured (defined) by heat insulating members 14a and 14b made of polystyrene foam, respectively. The heat insulating members 14a and 14b are not limited to foamed polystyrene.

  Further, in the housing 20 of the showcase unit 10, a second path extending in the vertical direction is provided behind the heat insulating member 14b, that is, behind the housing 20 separated from the second portion 13b by the heat insulating member 14b. (Exhaust heat duct, exhaust heat space, exhaust heat path) 15 is provided. The upper part of the exhaust heat path 15 is connected to a plurality of exhaust ports 18 formed in the upper wall 22 of the housing 20 of the showcase unit 10.

  Further, an introduction space 80 for sucking outside air into the exhaust heat path 15 is provided inside the showcase unit 10 behind the exhaust heat path 15. The introduction space 80 is separated from the exhaust heat path 15 by the partition 81. The rear of the introduction space 80 is the rear wall 25 of the housing 20, and the rear wall 25 is provided with an opening 82 for sucking outside air. When the showcase unit 10 is disposed near a store wall or the like (when the rear wall 25 is brought into close contact with the store wall or the like), the opening 82 for sucking outside air is provided in the side wall 23, the side wall 24, or the lower wall 26. It is also possible to arrange them.

  A fan (fan unit) 61 for sucking outside air and blowing it out to the heat exhaust path 15 is disposed on the heat exhaust path 15 side of the partition 81. Therefore, when the fan 61 is driven, outside air is jetted into the exhaust heat path 15 through the introduction space 80 as indicated by an arrow in FIG.

  The four cooling units 50 arranged in the air conditioning room 40 are supported by a heat insulating wall 14b for isolating the second portion 13b and the exhaust heat path 15 along the horizontal direction, that is, the X direction. Arranged in a state. Each cooling unit 50 moves the heat of the air (wind) passing through the blower path 13 to the exhaust heat path 15, and the cooled air (cold air) is sent by the crossflow fan 41 arranged at the upper part of the blower path 13. The air is blown out from the upper opening 17 as cold air.

  As a result, air flows into the air passage 13 such that the air sucked from the opening (suction port) 16 at the lower end of the storage chamber 11 is cooled and blown out from the opening (outlet port) 17 at the rear upper part of the storage chamber 11. Is formed. In other words, the storage device 1 of this example is a refrigeration storage device of the type that circulates air between the storage chamber 11 and the first path 13, and the storage device 1 is opened from the storage chamber 11. The air sucked through 16 is cooled in the second portion 13 b of the air blowing path 13, and cool air is blown out into the storage chamber 11 through the opening 17.

  In this example, a Peltier element unit is used as each cooling unit 50. As shown in FIGS. 3 and 4, each Peltier element unit 50 includes a Peltier element 51, a first fin unit 52, and a second fin unit 53. The first fin unit 52 is connected to the Peltier element 51 and is provided on the first plate 52 a provided along the air supply path 13, and the second portion 13 b of the air supply path 13 provided on the first plate 52 a. And the first fin 52b exposed to the surface. The second fin unit 53 is connected to the Peltier element 51 and is provided on the second plate 53a provided along the heat exhaust path 15 and on the second plate 53a and exposed to the heat exhaust path 15. The second fin 53b is provided. In this example, the first fins 52b and the second fins 53b are pin fins, and increase the efficiency (heat exchange efficiency) of moving the heat of the air in the second portion 13b to the exhaust heat path 15.

  Also, as shown in FIG. 3, four water-absorbing members 100 having water absorption are arranged on the lower sides of the four first fin units 52 (in FIG. 3, one is shown as a representative). ). In this example, each of the water absorbing members 100 is provided such that the upper end 100a thereof is in contact with the lower end of the plate 52a of the corresponding first fin unit 52. Moreover, in this example, the water absorbing member 100 is provided below the corresponding first fin 52b so as to extend vertically along the second portion 13b of the blowing path extending in the vertical direction. .

  The water absorbing member 100 absorbs the drain generated in the first fin 52b at the upper end 100a, and by capillarity (capillary phenomenon, surface tension of water) from the upper end 100a to the lower end 100b of the water absorbing member 100, This is for moving in the direction (downward) along the second portion 13b of the air blowing path 13.

  That is, when condensation occurs on the first fin 52b using the pin fins and they gather to form a droplet (drain), the condensation is collected while moving to the lower fin 52b by gravity, thereby reducing the size of the droplet. Becomes larger. In many cases, the wind pressure received by the droplets, the weight of the droplets, the surface tension of the droplets, and the like are balanced below the fin unit 52 to obstruct the wind (air) passing through the fins 52b. Loss rises and becomes a factor which reduces the contact area of the fin 52b. If the liquid droplets further accumulate and the balance is lost, the liquid droplets are dropped or blown off by the wind pressure and removed from the fin unit 52. Until then, the drain (liquid) Drop) is a major factor that reduces the ability of the fin unit 52. The water absorbing member 100 balances the liquid droplets collected in the lower part of the fin unit 52 by contacting the drain accumulated in the lower part of the fin unit 52 or by contacting the liquid level on the surface of the plate 52a. Breaks down and prevents the droplet size from increasing. The water absorbing member 100 is considered to absorb drain from the fin unit 52.

  In this example, in the 2nd part 13b of the ventilation path 13, since air distribute | circulates upwards from the downward direction, it is preferable that the water absorption member 100 does not deform | transform even if air distribute | circulates upwards from the downward direction. As the water absorbing member 100, so-called evaporative paper having good water absorbing performance can be used. However, as described above, the water absorbing member 100 is intended to move the absorbed drain in the direction along the second portion 13b of the blowing path 13 by capillary action, and evaporates the absorbed drain. It is not intended to be. The water absorbing member 100 may be any member that absorbs drain and can move the drain by capillary action, and is not limited to evaporative paper. As the water absorbing member 100, for example, a member configured to have water-absorbing paper or cloth can be used.

  The drain absorbed by the water absorbing member 100 finally drips downward as droplets from the lower end 100b. Therefore, a drain pan 110 is provided below the water absorbing member 100 as a means for receiving the drain. A drain port 110a is provided at the bottom of the drain pan 110, and the drain accumulated in the drain pan 110 is stored in the drain tank 73 via the drain port 110a. As will be described later, the drain tank 73 is provided at the bottom of the exhaust heat path 15.

  By the way, since the drain generated in the first fin 52b has a low temperature, the drain absorbed by the water absorbing member 100 also has a low temperature. Therefore, according to the storage device 1, when the temperature of the air flowing through the second portion 13 b of the air blowing path 13 is higher than the drain absorbed by the water absorbing member 100, the air flows through the second portion 13 b of the air blowing path 13. The air to be precooled is within the range of the sensible heat of the drain absorbed by the water absorbing member 100.

  As shown in FIGS. 3 and 4, the exhaust heat path 15 is directed to the second fin unit 53 of the Peltier element 51 of the plurality of Peltier element units 50 and in a direction perpendicular to the second plate 53 a (Z A box fan (fan unit) 61 arranged to blow air from the front side of the direction and a wind direction guide 62 arranged below the second fin unit 53 are provided. As shown in FIG. 4, the wind from a part of the fan units 61 is guided to the substrate 71 by the wind direction guide 62 and used for heat dissipation of the substrate 71. Further, the wind from some fan units 61 is directed to the drain tank 73 disposed in the exhaust heat path 15 and the evaporation member 72 to self-evaporate the drain of the drain tank 73. And it is utilized for the self-evaporation of drain. The evaporating member 72 is a member made of water-absorbing paper or cloth, and is exposed on the left side of the exhaust heat path 15. The evaporating member 72 is drain accumulated in the drain tank 73 by the air passing through the exhaust heat path 15. Is vaporized.

  In the storage device 1, the air inside the storage chamber 11 is driven by the cross flow fan 41 so that the air in the storage chamber 11 is formed at the lower end of the outlet 12 (below the front end of the storage chamber 11). The air is sucked into the air passage 13 from one end side (the inlet side of the first portion 13 a) 13 c of the air passage 13 through the opening 16. The sucked air flows through the first portion 13a and the second portion 13b of the air blowing path 13. In the process of flowing through the second portion 13b from the lower side to the upper side, the sucked air is precooled by the drain of the water absorbing member 100 basically within the range of the sensible heat of the drain. Furthermore, the air precooled by the drain of the water absorbing member 100 is cooled by being exchanged with the Peltier element 51 via the first fin unit 52. The cooled air (cold air) is supplied to the other end side (second portion) through a plurality of second openings 17 formed on the upper rear side of the storage chamber 11 (the rear side of the upper end portion of the storage chamber 11). 13 b is discharged into the storage chamber 11 from the outlet 13 d and supplied to the storage chamber 11 so that an air curtain is formed at the outlet 12.

  When the door unit 30 is removed and the storage device 1 is used as an open type storage device, the temperature difference (Δt) between the outside air and the storage chamber 11 is set smaller than when the storage device 1 is used as a closed type storage device. Often. In such a case, a large amount of outside air is sucked into the blowing path 13 from one end side (the inlet side of the first portion 13a) 13c of the blowing path 13. However, since the temperature difference is small, the amount of drain generated in the first fin 52b is relatively small. Even if drain is generated in the first fin 52 b, it is absorbed by the water absorbing member 100, guided downward by capillary action, falls as a droplet into the drain pan 110, and is collected in the drain tank 73.

  When the door unit 30 is attached and the storage device 1 is used as a closed type storage device, the temperature difference (Δt) between the outside air and the storage chamber 11 is set larger than when the storage device 1 is used as an open type storage device. Often. When the door members 32a and 32b are closed, the outside air is difficult to be sucked into the air blowing path 13, so that the temperature difference (Δt) with the first fin 52b is relatively small. However, when the door member 32a and / or 32b is opened for the purpose of taking out a refrigerated object or replenishing merchandise, a relatively high temperature outside air (the temperature in the storage chamber 11) is opened in the air passage 13. Hotter air). When the high-temperature outside air is rapidly cooled, the relative humidity increases and condensation occurs in the first fins 52b, so that drainage is likely to occur rapidly. Even in such a case, the drain generated in the first fin 52 b is absorbed by the water absorbing member 100, guided downward by capillary action, falls as a droplet into the drain pan 110, and drain tank 73. To be collected. Therefore, the drain does not accumulate in the first fin 52b and clogging is not caused.

  In the storage device 1, the drain generated in the first fin 52 b is absorbed by the water absorbing member 100 by capillary action. For this reason, in the second portion 13b of the air blowing path 13, even if air flows upward from below, the water absorption is not affected by the air flow or without affecting the air flow. The drain absorbed by the member 100 can be moved downward from above.

  Further, when the door member 32a and / or 32b is opened, the temperature of the storage chamber 11 is increased, so that the thermal load applied to the Peltier element unit 50 is increased. In the storage device 1 of this example, the door member 32a and / or 32b is opened, the timing at which the thermal load applied to the Peltier element unit 50 rises, and the drain is generated in the first fin 52b and absorbed by the water absorbing member 100. The timing at which the air flows through the second portion 13b of the air blowing path 13 can be precooled within the range of sensible heat of the generated drain (cold water). Therefore, when the door member 32a and / or 32b is opened, the thermal load applied to the Peltier element unit 50 can be reduced.

  As described above, according to the storage device 1, the water absorbing member 100 capable of absorbing drain from the first fin 52 b extends along a part of the second portion 13 b of the blowing path 13. Even if drain is generated in one fin 52b, the drain can be absorbed by the water absorbing member 100. Therefore, the heat exchange efficiency in the 1st fin 52b can be kept favorable. Further, the drain sucked by the water absorbing member 100 can be moved along a part of the second portion 13b of the air blowing path 13 by capillary action. Even if the drain is further generated in the first fin 52b, the drain can be sequentially moved along a part of the second portion 13b of the blowing path 13.

  Further, according to the storage device 1, it is possible to prevent the contact area of the fin from being reduced or the pressure loss from being increased by the drain even under use conditions where a large amount of drain is generated. Therefore, the fin pitch can be narrowed and the contact area can be widened by a compact fin unit. For example, in the pin fin 52b, the density of the pins can be increased. Furthermore, by adopting the Peltier element 51, it is possible to provide a cooling unit 50 that is compact and can maintain a high cooling capacity. For this reason, the storage device 1 having this cooling unit (Peltier element unit) 50 is easier to miniaturize than a storage device having a cooling unit equipped with a compressor, and a shelf called a gondola in a convenience store ( It is suitable as a small storage device installed on a shelf on which products are displayed at room temperature.

  In this example, four cooling units (Peltier element units) 50 are provided, but the number of cooling units is arbitrary, and the capacity of the cooling unit, the size of the storage chamber, the target temperature of the storage chamber, etc. It can be determined in consideration.

  In this example, the cooling unit 50 includes a Peltier element 51 and a first fin (heat absorption side fin) 52b. However, the cooling unit is provided in the first path (air blowing path). What is necessary is just to be provided with the exposed 1st fin (fin on the heat absorption side), and it is not limited to the thing provided with the Peltier device. The cooling unit may include a compressor and a first fin exposed in the first path. In the present embodiment, the first path is referred to as the air supply path including the suction side, but if the heat absorption side fin is exposed, it may be the suction side path or the discharge side path. Good.

  Furthermore, in this example, the water absorbing member 100 is connected to the first plate 52a of the first fin unit 52, but the position where the water absorbing member is provided is a position where the drain can be absorbed from the first fin. Is optional. For example, the water absorbing member may be provided so as to be connected to a part of the first fin.
