When the position of the display room is high, the display room is easily detached from the customer's line of sight (line of sight) when installed on the counter, and the inside of the display room is difficult to see. In particular, since the line of sight of children is low, it is difficult to see the inside of the display room.

  Moreover, if the machine room is provided under the heat insulating material, the ratio of the size of the display room to the entire open showcase is reduced. When installed on a counter, the size of the entire open showcase is often limited to some extent, resulting in a narrow display room and fewer products that can be displayed inside the display room.

  Further, the desktop refrigerated showcase is enlarged in the vertical direction as much as the machine room is provided, so that there may be a feeling of pressure when the open showcase is installed on the counter.

  One embodiment of the present invention is a showcase device for displaying products in a refrigerated and / or frozen state. The showcase device includes an upper case that forms a display chamber, a lower case that forms a machine room for housing a cooling unit that cools the display chamber via a refrigerant, a rear portion of the upper case, and a rear portion of the lower case. And a connection part that can suspend the lower case from the upper case, and a path for circulating the coolant up and down along the inside or outside of the connection part.

  According to this showcase device, the lower case can be installed in a state of being hung on the upper case. Therefore, for example, only the upper case is mounted on a counter or table, the lower case is suspended on the upper case, the lower case is hidden under the counter or table, and only the upper case is on the counter or table. It is possible to install the showcase device in a certain state (exposed state). According to this showcase device, although it is a showcase that can be displayed in a refrigerated or frozen state, when viewed from the front, only the upper case can be seen on the counter, table, etc., and the machine room under the counter, table, etc. The lower case forming the cover is hidden, and when viewed from the rear, the upper case and the lower case can be installed so as to be seen as one housing.

FIG. 3 is a front view of the showcase device 1a of FIG. FIG. 4 schematically shows a schematic configuration of the showcase device 1a of FIG. 1 from the side. FIG. 5 shows a side view of the showcase device 1a of FIG.

  This showcase device 1a displays and displays the function as a device (cooling storage, refrigerator, refrigeration / refrigeration device) for refrigeration and / or freezing the product A such as food, beverages and semi-processed products. It also has a function as a showcase. That is, product A is a beverage product (typically juice, shake, iced coffee) that is preferably provided in a refrigerated or frozen state, and a food product that is preferably stored and provided in a refrigerated or frozen state (typically Includes ice cream), and semi-processed products (typically bread dough, frozen food) that are preferably stored in a refrigerated or frozen state and heated. The showcase device 1a is suitable for use in, for example, a store such as a convenience store, which is installed on a counter 100 such as a cashier counter and provides goods to customers waiting for cashiers.

  The showcase device 1a of this example is a freezing showcase device (freezer). For example, iced coffee cups with ice are displayed and displayed in the display room 11, these are kept cold, and ice coffee is self-processed. It can be suitably used for a new sales form of selling at. In the showcase device 1a of the present example, the display chamber 11 is maintained at a temperature at which ice can be maintained (cold), for example, about −5 ° C. to −10 ° C.

  In detail, this showcase device 1a arranges (forms) the display chamber 11 in the upper part, and arranges the machine room 21 that houses the cooling unit 40 for cooling the display chamber 11 via the liquid refrigerant (in the lower part) ( A housing 2 that forms a space S in which the top plate 101 of the register counter 100 can be inserted between the display chamber 11 and the machine chamber 21.

In addition, the cooling unit 40 provided with the compressor 41 for pressurizing and circulating the refrigerant is suitable for maintaining the display room from refrigeration to refrigeration conditions. On the other hand, when refrigeration is hardly required and only refrigeration is required, a cooling unit 40 including a Peltier element unit can be employed, and cold water can be employed as a refrigerant.

  The lower case 20 is formed in a size and weight that can be suspended from the upper case 10. The lower case 20 is formed, for example, with a width in the left-right direction of about 560 mm, a height of about 200 mm, and a depth of about 500 mm. The rear surface of the lower case 20 (the outer surface of the rear wall 22f) 29 is substantially the same as the rear surface 19 so as not to protrude rearward (inside the cash register counter) with respect to the rear surface (the outer surface of the rear wall 12f) 19 of the upper case 10. It lies on the same vertical plane F.

  The connecting portion 30 is formed integrally with the lower case 20, extends upward from the lower case 20, and is connected to the upper case 10. The connecting portion 30 is also formed along the rear wall 12f of the upper case 10 and the rear wall 22f of the lower case 20 so as not to protrude rearward (inside the cash register counter). That is, the rear surface 39 of the connecting portion 30, the rear surface of the upper case 10 (the outer surface of the rear wall 12f) 19, and the rear surface of the lower case 20 (the outer surface of the rear wall 22f) 29 are on the same substantially vertical plane F. Located (see FIG. 5). The showcase device 1a has a space where the connecting portion 30 is hollow and is a part of the refrigerant path 50, and a path 51 for circulating the refrigerant up and down along the inside of the connecting portion 30 is provided. Yes.

  The size (height) of the space S formed between the upper case 10 and the lower case 20 is a size (height) into which the top plate 101 of the registration counter 100 can be inserted. Considering the thickness of the general top plate 101 of the cashier counter 100 of the convenience store, the size (height) of the space S formed between the upper case 10 and the lower case 20 is, for example, 60 to 70 mm. It can be. Therefore, in this example, the height of the connecting portion 30 is about 65 mm. The connecting portion 30 may be formed so as to expand and contract. By doing in this way, even if the thickness of the top plate 101 changes, the showcase apparatus 1a can be installed according to the top plate 101.

  In addition, the showcase device 1a of the present example straddles the upper case 10, the connecting portion 30, and the lower case 20 so that the lower case 20 can be suitably used in a state where the lower case 20 is suspended from the upper case 10. A pair of substantially L-shaped reinforcing plates 60 are provided. The pair of substantially L-shaped reinforcing plates 60 are provided along the left and right side rear portions of the lower case 20 and the left and right side rear portions of the connecting portion 30, respectively, and penetrate the lower wall 12 b of the upper case 10. In the lower space 15 of the upper case 10 (see FIG. 5).

  In this showcase device 1a, for example, a substantially U-shaped reinforcing plate is used along the arrangement of the upper case 10, the connecting portion 30 and the lower case 20 so that the substantially U-shaped is directed horizontally, It is also possible to connect the lower case 20 (a substantially U-shaped reinforcing plate is provided so as to straddle the upper case 10, the connecting portion 30, and the lower case 20). However, in such a substantially U-shaped reinforcing plate (substantially U-shaped reinforcing plate), stress concentrates on the U-shaped corner portion, and a force is applied in the direction of opening in the vertical direction. Therefore, such a substantially U-shaped reinforcing plate may be deformed in the vertical direction or may be broken, and it is not much as a reinforcing member for holding the lower case 20 in a suspended state on the upper case 10. It may not be suitable.

  On the other hand, the substantially L-shaped reinforcing plate 60 is less likely to generate a stress that deforms in the vertical direction compared to the substantially U-shaped reinforcing plate (substantially U-shaped reinforcing plate), and stress concentration at the corner portion is reduced. Can be relaxed. Therefore, the substantially L-shaped reinforcing plate 60 is suitable as a reinforcing member for holding the lower case 20 in a state where it is suspended from the upper case 10. In addition, by giving “R” to the inside and / or outside of the corner portion of the substantially L-shaped reinforcing plate 60 (with a curved shape), there is a possibility that stress at the corner portion can be further reduced.

  Next, the cooling cycle 70 with which the showcase apparatus 1a of this example is provided is demonstrated. The cooling cycle 70 provided in the showcase device 1a of this example is a cooling cycle in which heat is exchanged between a refrigerant such as HFC-134a and air, and as shown in FIG. 4, air is exchanged by heat exchange with the refrigerant. The evaporator (evaporator) 71 that cools the air, the condenser 72 that exchanges heat between the compressed gaseous (gas phase) refrigerant and the air to make the refrigerant liquid (liquid phase), and pressurizes the refrigerant And a compressor 41 for circulation. The evaporator 71 is accompanied by a decompressor 71 a and is disposed in the lower space 15 of the upper case 10. Another configuration of the cooling cycle 70 is arranged in the machine room 21 of the lower case 20 as the cooling unit 40, and the condenser 72 is arranged close to the front side inside the lower case 20. The compressor 41 is disposed from the approximate center inside the lower case 20 to the rear side. The operation of the compressor 41 is controlled by a control unit 73 disposed on the rear side inside the lower case 20 so that it can be easily operated from the outside. The evaporator 71, the condenser 72, and the compressor 41 are connected by a refrigerant path 50 including a path 51 that circulates the refrigerant up and down along the inside of the connecting portion 30 to cool the refrigerant.

  The lower case 20 is provided with a first opening 23 in the front wall 22c and a second opening 24 in the rear wall 22f. Further, a condenser 72 is disposed in the machine chamber 21 of the lower case 20 so as to face the first opening 23, and further for exhaust heat so as to face the first opening 23 across the condenser 72. A fan 75 is provided. The fan 75 is controlled by the control unit 73, and by rotating the fan 75, a wind flow from the second opening 24 toward the first opening 23 is formed, and the inside of the machine chamber 21 and the condenser 72 are cooled. Is done. The flow of the wind may be from the first opening 23 toward the second opening 24. In the upper case 10, the air in the display chamber 11 is cooled by heat exchange with the refrigerant supplied from the cooling unit 40 of the machine room 21, and thereby the inside of the display chamber 11 is kept in a frozen state.

  On the rear wall 22 f of the lower case 20, a control panel 79 for adjusting the temperature or the like in the display chamber 11 appears outside in relation to the control unit 73. The control panel 79 is electrically connected to the control unit 73. By operating the control panel 79, the temperature in the display chamber 11 can be arbitrarily set. Further, a temperature detector 74 is disposed inside the display chamber 11, and the control unit 73 controls the operation of the compressor 41 based on the temperature detected by the temperature detector 74. As described above, in this example, the inside of the display chamber 11 is maintained at a set temperature (about −5 ° C. to −10 ° C.) suitable for freezing, but the set temperature can be changed and refrigerated. It is also possible to set a suitable temperature around −2 ° C. or other temperature range.

  FIG. 6 is a perspective view of the showcase device 1a shown in FIG. FIG. 7 is a perspective view of the showcase device 1a shown in FIG. In the figure, reference numeral 120 denotes a register.

  In the showcase device 1a of this example, the space S formed between the upper case 10 and the lower case 20 is a space into which the top plate 101 of the register counter 100 can be inserted. For this reason, according to this showcase device 1 a, when the upper case 10 is mounted on the top plate 101, the lower case 20 becomes the lower side of the top plate 101. Therefore, when only the upper case 10 is mounted on the top plate 101 of the checkout counter 100, the lower case 20 is suspended by the upper case 10 and the lower case 20 is hidden (entered) under the top plate 101 of the checkout counter 100. The upper case 10 can be installed such that only the upper case 10 is on the top plate 101 of the register counter 100 (in an exposed state).

  Therefore, the showcase device 1a of the present example is a showcase that can be displayed in a frozen state. However, when the showcase device 1a is arranged as described above, as shown in FIG. Only the upper case 10 can be seen above 101, and when viewed from the rear, the upper case 10 and the lower case 20 appear to be composed of one housing 2 including the connecting portion 30.

  In a convenience store cashier counter 100 or the like, a shelf board 102 is usually provided inside, and a shopping bag or the like can be placed on the shelf board 102 (a space between the top board 101 and the shelf board 102). It has become. Since the lower case 20 is suspended from the upper case 10, the showcase device 1a of the present example can be typically installed with the lower case 20 suspended. As described above, when the shelf plate 102 is provided inside the cashier counter 100, the lower case 20 can be inserted between the top plate 101 and the shelf plate 102. Furthermore, a support member 80 (see FIG. 5) may be provided between the lower case 20 and the shelf plate 102, and the lower case 20 may be supported by the shelf plate 102 via the support member 80. When the height of the shelf board 102 inside the register counter 100 can be changed, the lower case 20 may be mounted on the shelf board 102 by changing the height of the shelf board 102. Supporting the lower case 20 by the shelf plate 102 is effective for installing the showcase device 1a more stably. Moreover, when the force which falls to the upper case 10 acts, the lower case 20 can contact the back side of the top plate 101, it opposes such a force, and it can suppress that the upper case 10 falls. Therefore, the showcase device 1a is highly stable against vibration caused by an earthquake or the like.

  As described above, according to the showcase device 1a, when viewed from the rear, the lower case 20 including the machine room 21 and the upper case 10 including the display room 11 are mechanically connected to each other by the connecting portion 30. When viewed from above, the upper case 10 including the display chamber 11 in which the product A can be displayed in a frozen state is designed to appear on the cashier counter 100 in a state separated from the lower case 20 including the machine chamber 21. be able to. Therefore, the design of the upper case 10 can be separated from the lower case 20 including the machine room 21 except for the connecting portion 30, and the design flexibility of the upper case 10 is increased. For this reason, the upper case 10 can be made low and the display room 11 can be provided in the low position where a customer looks into from the upper direction. If it is this design, since the inside of the display room 11 can be made to visually recognize well, it is effective for sales promotion. In particular, it is suitable for selling an ice cream or the like for which a product is expected to be seen from the upper side next to the cash register.

  Moreover, according to this showcase apparatus 1a, the path | route 51 which circulates a refrigerant | coolant up and down along the inside of the connection part 30 which connects the rear part of the upper case 10 and the rear part of the lower case 20 is provided. For this reason, the lower case 20 forming the machine room 21 is disposed under the top plate 101 of the cashier counter 100 without subjecting the top plate 101 of the cashier counter 100 to drilling or notching. Only the upper case 10 forming the display chamber 11 maintained in a state can be arranged on the top plate 101 of the cashier counter 100. Therefore, the showcase device 1a can be installed at an appropriate position on the cashier counter 100 and can be moved easily. If the showcase device 1a once installed on the cashier counter 100 is removed, the cashier counter 100 can be used in the same manner as before the showcase device 1a is installed.
