Description

  The technology disclosed by the present specification relates to a refrigerated showcase provided with a heat insulation box whose inside is a refrigerated room, and more particularly to a refrigerated showcase in which a plurality of shelf boards are attached in a multistage manner in the refrigerated room.

In a kitchen or the like of a sushi shop, a refrigerated showcase may be installed in the vicinity of the counter. In the refrigerated compartment in the refrigerated showcase, foodstuffs (stored material) such as fresh fish and shellfish to be used as sushi neta are stored, and if necessary, the cook opens the front door to take out the foodstuffs and cooks on the cooking table Do.
In a refrigerated showcase used for such a purpose, it is also assumed that food is stored in the refrigerated compartment in a state of being exposed in consideration of convenience in cooking. Therefore, in order to protect the food from drying and to prevent the decrease in freshness of the food due to contact with the circulating cold air, the cold air is not forced to circulate in the cold storage using a fan in the cold storage like a general cold storage, It is desirable to use a natural cooling system in which cold air is circulated by convection based on a temperature difference or the like.
In addition, unlike the refrigerated showcases set up in front of the sushi restaurant's seat, the refrigerated showcases installed in the kitchen etc., in addition to the emphasis on convenience and storage capacity over aesthetics, in addition to the food It is also frequently carried out. Therefore, it is preferable to install a plurality of shelf boards in a multistage manner in the refrigerator compartment so as to be able to store many foods.

As an example of a naturally cooled refrigerated showcase, the one described in Patent Document 1 below is known. In this refrigerated showcase, a cooler is installed on the top surface of the storage compartment so that cold air is lowered into the storage compartment below. Moreover, the vertical freezer is disclosed by patent document 2 as another example of a natural-cooling-type. In this vertical freezer, a so-called pipe-on-sheet is provided in which the evaporation pipe (cooling pipe) of the refrigeration apparatus is arranged in a serpentine manner on the outer surface of the inner box of the heat insulation box, that is, top wall, back wall, side wall and bottom wall. The inside of the storage is cooled by a cooling method, and evaporation pipes are also disposed on a shelf board which divides the storage inside into upper and lower parts.
On the other hand, a refrigerator or the like in which a plurality of shelf boards are vertically arranged in a refrigerator compartment is widely used as a household refrigerator or the like. In such a multistage refrigerator, it is between the rear end of the shelf board and the rear wall of the cold storage room for the purpose of causing condensation water generated on the inner surface of the rear wall to flow down by the cooling pipe disposed on the rear wall. It is common for shelf plates to be attached in such a way that a gap is formed.

Japanese Utility Model Publication 7-6671 Japanese Patent Laid-Open No. 3-158683

  However, in the case where the cooler is installed on the top surface of the chamber as in Patent Document 1, measures for condensation are required to increase the cost of the product, and the height dimension of the product also has to be increased. Moreover, when it is set as a structure like patent document 2, there exists a possibility that the dew condensation which arose by the evaporation pipe arrange | positioned by the top surface and shelf board of a refrigerator compartment may drip on a shelf board and stored goods, and a foodstuff in particular is exposed. It is difficult to apply to refrigerated showcases that may be stored as they are. Therefore, a refrigerated showcase in which a plurality of shelf boards are attached in the upper and lower stages in a state where the evaporation pipe is disposed only on the back surface and the bottom surface and a gap is formed between the back surface and the back of the refrigerator like a general refrigerator. When the fluid analysis of the temperature distribution in the refrigerator compartment is performed, a considerable temperature difference occurs between the upper and lower compartments in the refrigerator compartment, and the lower part is excessively cooled with respect to the upper It was revealed.

  In view of the above situation, the present specification discloses a refrigerated showcase in which the temperature distribution in the refrigerated compartment is homogenized while preventing drying of stored items.

  The refrigerated showcase disclosed by the present specification comprises a thermally insulated box body having an opening at the front, and a main body having a refrigerating compartment inside, and is openably and closably attached to the opening so that the inside of the refrigerating compartment can be viewed. A door, a plurality of shelf boards arranged vertically in the refrigerator compartment and mounted in a multistage manner, and a cooling pipe disposed on the back wall of the main body, the shelf board being from the other plate surface side to the other Air circulation to the side of the plate surface, and is mounted in the refrigerator compartment in such a manner that no gap is formed between the rear end of the shelf and the rear wall of the main body. .

  According to the above configuration, in the refrigerated showcase where convenience and storage capacity are secured by the multistage type shelf board, by arranging the cooling pipe on the back wall of the main body, it is possible to suppress the drying of the stored items while suppressing the natural The refrigeration chamber is cooled using convection. Here, it is assumed that the shelf mounted in the refrigerator compartment is not allowed to circulate air through the plate surface, and that refrigeration is performed in such a manner that no gap is formed between the rear end of the shelf and the rear wall of the main body. By being installed indoors, the cold air cooled by the cooling pipe disposed on the back wall does not descend to the lower stage through the shelf itself or through the gap on the back side of the shelf, and the cold air Excessive cooling of the lower side of the refrigerator compartment is suppressed by the descent. At the same time, convection that circulates in each of the plurality of storage spaces divided up and down by the shelf plates is likely to occur, and the temperature distribution in the refrigerator compartment can be homogenized. As a result, it becomes possible to cool stored items such as food at a stable appropriate temperature at any level, and the user does not have to consider which level to store for each food, and the convenience is improved. In addition, when a thermistor for detecting the temperature of the refrigerator compartment to control the operation of the refrigeration system is attached to the refrigerator compartment, the degree of freedom in selecting the attachment position is also increased. Furthermore, since the load of the refrigeration system for maintaining the refrigeration compartment at a predetermined temperature is reduced, and an inexpensive compressor or the like with a smaller output can be used, the product cost can be reduced.

  In the refrigerated showcase disclosed by the present specification, the cooling pipe is disposed in a serpentine shape in which horizontally extending straight portions are vertically arranged only on the back wall of the main body, and the straight portions of the cooling pipe Preferably, at least one storage space is provided for each of the storage spaces formed by dividing the refrigerator compartment up and down by the plurality of shelf boards.

  According to the above configuration, by arranging one or more cooling pipes for each of the storage spaces partitioned and formed side by side by the plurality of shelf boards, cooling for each storage space becomes possible, and as a result, refrigeration The temperature distribution of the whole room can be adjusted uniformly. In addition, by arranging the cooling pipe only on the back wall, the possibility of excessive cooling of the lower stage is reduced, and the number of processing and assembling steps is reduced compared with the configuration in which the cooling pipe is also arranged on the bottom, Manufacturing costs can be reduced.

  In the refrigerated showcase disclosed by the present specification, the distance between the front end of the plurality of shelf boards and the rear surface of the door is preferably 10 mm or less.

  If the distance between the front end of the shelf board and the rear surface of the door is 10 mm or less as in the above configuration, the movement of cold air that cuts across a plurality of storage spaces on the front side of the refrigerator compartment is reduced. Cold air naturally convects in the space. As a result, it is possible to further homogenize the temperature distribution of the entire cold storage room.

  Further, in the refrigerated showcase disclosed by the present specification, the plurality of shelf boards are attached to the cold storage room via a shelf board support member, and the shelf board support member is a back surface of the main body. It is preferable to be attached so that it may contact | abut on a wall, and to block | close between the rear end of these shelf boards and the back wall of the said main body.

When the shelf board itself is brought into contact with the back wall of the main body on which the cooling pipe is disposed, dew condensation water and attached dust and the like generated on the back wall will be led onto the shelf board as it is. Be concerned. In addition, when a plurality of shelf boards are detachably attached so that they can be adjusted to a desired height, a clearance for attaching and detaching is required. Therefore, between the rear end of the shelf boards and the back of the refrigerator compartment, It is difficult to maintain a closed state at all times. Furthermore, there is a concern that the rear end of the shelf plate in contact with the rear surface freezes with the dew condensation water, causing problems in the detachment of the shelf plate.
Therefore, if the shelf board supporting member is disposed between the rear end of the shelf board and the back wall of the main body as in the above configuration, condensed water etc. will not directly flow down on the shelf board, and the shelf board and storage You can keep things hygienic. Further, the shelf support member can hold the shelf and the rear wall of the main body in a stable closed state. Furthermore, since the freezing of the shelf board is avoided, the shelf board can be detached even during the operation of the refrigeration system, and the convenience is improved.

  In the refrigerated showcase disclosed by the present specification, the shelf support member is configured to support the support between a rear end that abuts the rear wall of the main body and the support on which the shelf is mounted. It is preferable to have the receiving part arranged below rather than.

  According to the above configuration, the condensed water generated on the back wall of the main body can be received by the receiving portion of the shelf board support member. Furthermore, if the inclination of the upper surface of the receiving part is appropriately adjusted and the received water is conducted to the left and right sides of the cold storage room and allowed to flow down at the back corner, condensation is prevented while avoiding contamination of the shelf board and stored items. Water can be drained from the bottom.

  According to the technology disclosed by the present specification, it is possible to provide a refrigerated showcase in which the temperature distribution in the refrigerator compartment is homogenized while preventing drying of stored items.

Subsequently, circulation of cold air in the refrigerator compartment 3 will be described with reference to FIG.
In the refrigerator compartment 3, the air cooled near the back wall 12 of the main body 1 functioning as a cooling wall as described above descends to cause a downflow on the back side in each storage space 31. The lowered cold air is turned by hitting the shelf board 50 (the bottom board 16 of the main body 1 for the lowermost storage space 31) mounted below each storage space 31, and the lower shelf board 50 (lowermost stage) Storage space 31 produces a cooling flow forward along the bottom plate 16). The air in the storage space 31 and the cold air moved to the front side while cooling the stored matter collide with the door 40 to prevent the forward movement, and at the same time, enter the cold storage room 3 through the door 40 not provided with the heat insulating material. It is warmed by the external heat that is received and generates an upward flow on the front side in each storage space 31. The air that has risen collides with the shelf plate 50 (the top wall of the main body 1 for the uppermost storage space 31) mounted above each storage space 31 and is turned around, and is moved backward along the upper shelf plate 50. Produces a flowing recurrent flow. This air, which has moved in the upper part of the storage space 31, is again cooled near the back wall 12 to produce a downflow. In this way, in each storage space 31, the downward flow downwards on the back side, the cooling flow moving forward in the lower portion, the upward flow upward on the front side, the upward section toward the rear The circulation path of cold air based on natural convection consisting of return flow moving is completed, and the inside of each storage space 31 is efficiently cooled without providing a fan or the like.

According to the present embodiment, the following effects can be obtained.
In the present embodiment, instead of forcibly circulating cold air in the refrigerator compartment 3 using a fan in the refrigerator, etc., a so-called pipe-on-sheet system in which the cooling pipe 60 is disposed on the back wall 12 of the main body 1 Since the inside of the room 3 is cooled and the cold air is circulated by natural convection, it is possible to cool the inside of the cold storage room 3 utilizing natural convection while suppressing the drying of the stored items.

Further, in the present embodiment, the shelf board 50 is formed of a plate material that does not allow the flow of air through the board surface, and a gap is formed between the rear end of the shelf board 50 and the back wall 12 of the main body 1. It mounted in the refrigerator compartment 3 in the aspect which is not formed. As a result, the cool air cooled by the cooling pipe 60 disposed on the back wall 12 passes through the shelf board 50 itself or passes through the gap on the back side of the shelf board 50, and a plurality of partitions are vertically divided by the shelf board. Between the storage space 31 of the storage unit and the storage space. Accordingly, excessive cooling of the lower side of the refrigerator compartment 3 is suppressed and, at the same time, cold air naturally convects in each storage space 31, so that the temperature distribution in the refrigerator compartment 3 can be homogenized.
Furthermore, in the present embodiment, since the distance between the front end of the shelf plate 50 and the rear surface of the door 40 is narrowed to 10 mm or less, the flow of cold air moving longitudinally across the plurality of storage spaces 31 in the front of the refrigerator compartment 3 Is reduced. Therefore, the homogenization of the temperature distribution of the whole inside of the refrigerator compartment 3 is achieved.
As a result of the above, it becomes possible to cool stored goods at a stable appropriate temperature in any stage, and the user does not have to consider which stage should be stored for each food, and convenience is improved. In addition, the degree of freedom in position selection when the thermistor for detecting the temperature of the refrigerator compartment 3 to control the operation of the refrigeration apparatus is installed in the refrigerator compartment 3 also increases. Furthermore, the load on the refrigeration system for maintaining the inside of the refrigerator compartment 3 at a predetermined temperature is reduced, and an inexpensive compressor or the like with a smaller output can be used, and as a result, the product cost of the refrigerator showcase 10 is reduced. be able to.

  Further, in the present embodiment, by arranging two linear portions 61 of the cooling pipe 60 for each of the storage spaces 31 partitioned and formed by the plurality of shelf boards 50, cooling for each storage space 31 becomes possible. The temperature distribution of the whole cold storage 3 can be adjusted. Further, since the cooling pipe 60 is disposed only on the back wall 12, the number of processing and assembling steps can be reduced as compared with the configuration in which the cooling pipe 60 is disposed also on the bottom wall 15, and the manufacturing cost of the refrigerated showcase 10 can be reduced.

Further, in the present embodiment, the clearance between the rear end of the shelf plate 50 and the back wall 12 of the main body 1 is closed by the rear shelf plate supporting member 90R. Therefore, the condensed water W and the like generated on the back wall 12 does not directly flow down on the shelf board, and the shelf board 50 and stored items can be kept hygienic. In the present embodiment, the dew condensation water W and the like are received by the receiving portion 93 of the rear shelf support member 90R. Furthermore, if the inclination of the upper surface of the receiving part is appropriately adjusted and the received water is conducted to the left and right sides of the cold storage room and allowed to flow down at the back corner, condensation is prevented while avoiding contamination of the shelf board and stored items. Water can be drained from the bottom.
In the present embodiment, once the mounting position of the rear shelf pillar 70R in the front-rear direction is appropriately adjusted and the rear shelf support member 90R is installed, the shelf is removed even when the shelf 50 is removed, etc. It can be held closed between the plate and the back wall of the body. Furthermore, since the freezing of the shelf board is avoided, the shelf board can be detached even during the operation of the refrigeration system, and the convenience is improved.
