Hereinafter, the front side in FIG. 1 will be referred to as the front side (front side) of the freezing / refrigeration showcase, and description will be made with reference to the vertical and horizontal directions when viewed from the front side.

  The freezer / refrigerated showcase 1 of the present embodiment is installed to display products such as daily foods and fresh foods in a cold state in a supermarket, a convenience store or the like. As shown in FIG. 1, the freezing / refrigerating showcase 1 includes a case main body 21 provided at the top for cooling and storing products (not shown), a base 3 provided below the case main body 21, The refrigerator unit 35 (compressor 43, condenser 44, and intake / exhaust fan 46, which will be described later) housed in a machine chamber 32 formed mainly inside the base 3 is included in the refrigerator unit 35. A built-in showcase capable of cooling the inside of the cold storage chamber 2 defined in the case body 21 by performing a refrigeration cycle in the refrigeration / refrigeration showcase 1 by the connected evaporator 41 and an expansion valve (not shown). It is. In the present embodiment, the refrigeration / refrigeration showcase 1 is arranged so as to be incorporated into a part of the article display shelf 10. The details of the article display shelf 10 will be described later.

  As shown in FIG. 2, the case main body 21 includes an upper unit 20 including a stirring fan 48 (blower fan) and a controller 49, an outer case 22 having a substantially inverted L shape in cross section, This is mainly composed of an inner case 23 having a substantially inverted L-shape in cross section and panel units 27 and 27 formed of a pair of light-projecting glass, and defines a cold insulation chamber 2. ing.

  Further, the case body 21 has an upper unit 20 disposed at the upper end of the case body 21 over the left and right ends, and panel units 27, 27 are disposed at the left and right ends of the case body 21. A front panel 28 made of glass, acrylic resin, or the like is erected on the front end of the lower portion 21b over the left and right ends, and is configured in a box shape having an opening from the front side to the upper side.

  In the case body 21, rear ends of brackets 24, 24 extending in the front-rear direction are attached to the back surface portion 23a of the inner case 23, and a shelf plate 25 is attached to the brackets 24, 24 from above. As a result, in the cold room 2, products can be displayed on the top surfaces of the shelf 25 and the bottom 23 b of the inner case 23.

  Further, on the back side and the bottom side of the case main body 21, a cold air circulation passage 26 having a substantially inverted L shape in a side sectional view is formed between the outer case 22 and the inner case 23. Are provided with an evaporator 41 that constitutes a refrigeration cycle, and a cool air circulation blower 42 that sends air toward the evaporator 41. In addition, the evaporator 41 can heat-exchange by the refrigerating cycle using a refrigerant | coolant, and can cool the surrounding air.

  Further, between the case main body 21 and the lower edge of the front end of the upper unit 20, a cold air outlet 7 </ b> A communicating with the cold air circulation passage 26 is formed forward and obliquely downward, and is formed below the back surface portion 23 a of the inner case 23. A cold air outlet 7B comprising a plurality of elongated holes communicating with the cold air circulation passage 26 is formed in a lateral direction, and opens upward at the front edge of the lower end 21b of the case body 21 to communicate with the cold air circulation passage 26. A cold air inlet 8 is formed.

  The refrigeration / refrigeration showcase 1 operates the cold air circulation blower 42 in the cold air circulation passage 26 so that the cold air cooled by the evaporator 41 is discharged from the upper air outlet 7A and the lower air outlet 7B to the lower air inlet. It is to be blown out toward the 8th. In addition, since the lower part 21b of the case main body 21 is arrange | positioned in the front position rather than the upper unit 20, it blows off diagonally toward the lower suction inlet 8 from the upper blower outlet 7A. .

  According to this, an air curtain is formed on the open surface on the front side of the case main body 21 by the airflow of cold air, and a part of the cold air flows into the cold insulation chamber 2, and the inside of the cold insulation chamber 2 from the lower outlet 7B. The state where the inside of the cold insulation chamber 2 is cooled by the cool air flowing into the air can be efficiently cooled and maintained. Further, the cold air sucked from the suction port 8 flows into the cold air circulation passage 26 and is sent again to the evaporator 41 by the cold air circulation blower 42 so that the cold air circulates efficiently.

  Moreover, since a part of the cool air blown out from the upper air outlet 7A and the lower air outlet 7B is guided to the suction port 8 by the front panel 28, the outflow of the cold air from the front surface of the case body 21 is suppressed. . Furthermore, the panel units 27 and 27 suppress the outflow of cold air from the left and right side portions of the case main body 21, and the cooling efficiency in the cold insulation chamber 2 is enhanced by the high heat insulation of the pair glass.

  Moreover, since the panel units 27 and 27 are formed of the pair glass, the visibility of the cold insulation chamber 2 is high even from the side.

  In the cold air circulation passage 26, a drainage portion (not shown) is provided at a predetermined position in front of the bottom 22 a of the outer case 22 constituting the bottom surface of the cold air circulation passage 26, and the drainage portion is provided in a machine chamber 32 which will be described later.

The refrigerator unit 35 is disposed substantially at the center of the machine room 32 when viewed from the front, from the opening 6 to the refrigerator unit 35 on the left side of the refrigerator unit 35, and A partition plate 34 is disposed from the lower end surface of the bottom 22 a of the outer case 22 to the upper end surface of the bottom plate 39. In addition, the opening part 34a of the partition plate 34 is formed in the substantially same shape as the left side surface of the condenser 44 mentioned later seeing from the front, and the filter 34b (refer FIG. 4) can be attached or detached. Furthermore, the filter 34b may be integrally formed with the partition plate 34.

  The refrigerator unit 35 includes a compressor 43 and a condenser 44 that are part of the refrigeration cycle, and an intake / exhaust fan 46 (exhaust fan). The intake / exhaust blower 46 is disposed on the right side of the condenser 44 when viewed from the front, and can blow air from the condenser 44 toward the compressor 43. The compressor 43 compresses the low-temperature and low-pressure refrigerant generated in the evaporator 41 in the refrigeration cycle, and the condenser 44 is disposed downstream of the compressor 43 in the refrigerant flow of the refrigeration cycle and performs heat exchange. Is.

  The electrical box contains a control device (not shown) that controls the operation of the freezer / refrigerated showcase 1. Note that a controller 49 disposed in the upper unit 20 is connected to the control device by wiring (not shown).

  As shown in FIGS. 1 and 2, the opening 6 of the machine chamber 32 has a cover member in which a plurality of vent holes 5 c formed vertically in the same range as the opening 6 are formed in eight rows in the left-right direction. 5 is attached to the front end portions of the side plates 37 and 37 of the machine room 32 so as to cover the opening 6. The cover member 5 has a plurality of vent holes 5c in the third and fourth rows from the left when the cover member 5 is viewed from the front and hits a substantially front portion of the partition plate 34 and the condenser 44, and is formed by the sheet member 5d (see FIG. 1). The plurality of vent holes 5c in the first and second rows from the left when the cover member 5 is viewed from the front are the front portions of the intake ports 6A described later, and 5 to 5 from the left when the cover member 5 is viewed from the front. The plurality of vent holes 5c in the eighth row are front portions of an exhaust port 6B described later. The cover member 5 is detachable because it is attached to the side plates 37, 37 by a magnet (not shown). Furthermore, the cover member 5 is not limited to a mode of being attached by a magnet, but is locked to the front end portions of the side plates 37 and 37 by forming a flange portion in part and forming a receiving portion of the flange portion on the side plates 37 and 37. It may be a mode that may be fixed to the front end portion of the side plates 37, 37 by bolts and nuts, and is not limited to a mode that is attached to the front end portion of the side plates 37, 37 of the machine room 32. .

  As shown in FIG. 4, the opening 6 of the machine room 32 has an intake port 6 </ b> A located to the left of the partition plate 34 when viewed from the front in the machine room 32 and a partition plate 34 when viewed from the front in the machine room 32. And an exhaust port 6B located on the right side of the exhaust air. The outside air is taken into the machine chamber 32 from the intake port 6A by the intake / exhaust fan 46, and the inside air in the machine chamber 32 is taken from the exhaust port 6B. It is discharged outward. At this time, the intake / exhaust fan 46 can discharge the inside air in the machine chamber 32 in a direction away from the intake port 6A. Furthermore, since the exhausted air is more heated than the outside air, it tends to rise. Therefore, the intake / exhaust blower 46 can blow the air exhausted to the outside after the heat exchange through the exhaust port 6B to a position far from the opening 6, so that the exhausted air is stored in the machine chamber 32. It is difficult to mix with the air sucked from outside through the opening 6. In FIG. 4, the illustration of the cover member 5 is omitted for convenience of explanation.

  The opening 6 side of the machine room 32 is divided into left and right by a partition plate 34, and the cover member 5 is provided with a sheet member 5d. Therefore, the opening 6 side from the intake port 6A side to the exhaust port 6B is downwardly viewed. A letter-shaped flow path is formed. This makes it easier to rotate the air from the left to the right in the machine room 32, and thus it becomes difficult for the air sucked through the opening 6 and the exhausted air to be mixed inside the machine room 32. Further, outside air is taken in from the left side of the cover member 5 detachably attached to the opening 6 of the machine room 32 by the intake / exhaust air blower 46, and the inside of the machine room 32 is turned in the left-right direction, and is passed through the right side of the opening 6. Therefore, the efficiency of heat exchange inside the machine room 32 is increased. Note that the opening 6 may be provided with a filter, for example, in the cover member 5 or the intake port 6 </ b> A so that dust and dust do not easily enter the inside of the machine room 32.

  As shown in FIGS. 3 and 4, kick plates 50 and 50 are fixed to the lower portions of the left and right ends of the base 3 from the bottom plate 39 to the side plates 37 and 37, respectively, so that they are protected from impact caused by contact. ing.

  As shown in FIG. 3, the freezer / refrigerated showcase 1 has four casters 4, 4,... Disposed at the four corners below the bottom plate 39 of the machine room 32. Since the refrigerated / refrigerated showcase 1 can be moved by this, it is easy to change the arrangement.

  In addition, side plates 51 are disposed between the panel unit 27 and the kick plate 50 on both sides of the freezer / refrigerated showcase 1.

  So far, the refrigeration / refrigeration showcase 1 has been described. Next, the dimensional relationship between the refrigeration / refrigeration showcase 1 and the article display shelf 10 and the refrigeration / refrigeration showcase 1 will be described with reference to FIGS. Will be described in which it is arranged so as to be incorporated into a part of the article display shelf 10. First, the article display shelf 10 will be described. Although the article display shelf 10 will be described in detail later, the front and rear configurations are substantially the same, so the front side will be described and the rear side description omitted.

  As shown in FIG. 1, the article display shelf 10 includes support columns 11, 11,... Arranged on the left and right and leg portions 12, 12 fixed to the front and rear from the lower ends of the support columns 11, 11,. ,..., And back plate units 16, 16 disposed between the columns 11, 11,. In addition, although a direct illustration is omitted, baseboards and headboards are respectively disposed on upper and lower ends of the columns 11, 11,.

  The rear ends of brackets 14, 14 extending in the front-rear direction are attached to the pair of left and right support columns 11, 11, and a shelf plate 15 is attached to the brackets 14, 14 from above.

  A kick plate 13 is disposed in front of the leg portions 12 and 12, and a shelf plate 17 is attached to the leg portions 12 and 12 and the kick plate 13 from above.

  Further, as shown in FIG. 2, the article display shelf 10 is an article display shelf 10 having substantially the same configuration on the front and rear sides with the support column 11 and the back plate unit 16 interposed therebetween. In addition, the goods display shelf 10 may be an aspect provided with the brackets 14 and 14 and the shelf board 15 etc. only in the front and rear inner side, and if it is this aspect, it can arrange | position to a wall surface.

  Further, as shown in FIGS. 1 and 5, adjusters 18 are provided on the lower surfaces of the support columns 11 and the leg portions 12, and by adjusting the heights of the adjusters 18, articles can be installed regardless of the installation location. The display shelf 10 can be installed in a horizontal state. Note that a caster may be provided instead of the adjuster 18.

  When installing the refrigerated / refrigerated showcase 1 on the article display shelf 10, the kick plates 13 and the shelf boards 17 of the article display shelf 10 are removed, and the brackets 14, 14 that hinder the installation of the refrigerated / refrigerated showcase 1, The installation space S is formed by removing the shelf board 15.

  As shown in FIG. 3, the freezing / refrigerating showcase 1 has an outer dimension W1 in the left-right direction of the kick plates 50, 50 of the freezing / refrigerated showcase 1 so that the left and right legs 12, 12 of the article display shelf 10 are left and right. It is designed to be shorter than the inner dimension W2 in the direction (W1 <W2).

  Moreover, the freezing / refrigeration showcase 1 is installed so that the lower end surfaces of the side plates 51, 51 are separated from the upper end surfaces of the leg portions 12, 12 of the article display shelf 10.

  With these configurations, the refrigeration / refrigeration showcase 1 does not interfere with the legs 12 and 12 of the article display shelf 10 that defines a part of the installation space S. 1 can be installed.

  As shown in FIG. 1, the outer dimension W3 in the left-right direction of the panel units 27, 27 is formed to be substantially the same dimension (W3 = W4) as the inner dimension W4 in the left-right direction of the columns 11, 11 of the article display shelf 10. Has been. Thereby, since the freezing / refrigeration showcase 1 can be installed in the installation space S without forming a gap between the support columns 11, 11 and the panel units 27, 27, the freezing / refrigeration showcase 1 and the article A sense of unity with the display shelf 10 can be produced.

  The lateral dimension W5 in the left-right direction of the side plates 51, 51 is designed to be substantially the same dimension (W5 <W6) slightly shorter than the core dimension W6 in the left-right direction of the support columns 11, 11. Further, the outside dimension W5 is substantially the same as the outside dimension W7 which is the maximum width of the refrigeration / refrigeration showcase 1 described later in detail. In other words, in the state where the freezer / refrigerated showcase 1 is installed in the installation space S, the inner rows of the left and right two rows of locking holes formed on the front surfaces of the columns 11 and 11 overlap the side plates 51 and 51. Thus, the outer row is exposed. For these reasons, the side ends of the freezer / refrigerated showcase 1 do not interfere with the mounting of the bracket 14 and the shelf board 15 in the display space of the article display shelf 10 adjacent to the freezer / refrigerated showcase 1. In addition, since the core dimension in the left-right direction of the leg parts 12 and 12 is substantially the same dimension as the core dimension W6 of the support | pillars 11 and 11, the core dimension in the left-right direction of the leg parts 12 and 12 is also set to the core dimension W6.

  Further, as shown in FIG. 5, the side plate 51 has a front-rear dimension D1 substantially the same as a dimension D2 from the front side surface of the column 11 of the article display shelf 10 to the front side surface of the kick plate 13 (D1 = D2). ) Is designed. Further, an extension part 51 a extending forward is formed at the upper front end edge of the side plate 51, and the external dimension D3 in the front-rear direction including the extension part 51 a is from the front side surface of the column 11 to the shelf plate 17. It is designed to have substantially the same dimension (D3 = D4) as the dimension D4 up to the front edge.

  With these configurations, the side plates 51, 51 are arranged so that the side plates 51, 51 are brought into contact with the support columns 11, 11 when the freezing / refrigeration showcase 1 is arranged in the installation space S, The installation position with the front end surface of the shelf board 17 of the article display shelf 10 can be aligned.

  As shown in FIG. 1, the front end surface of the cover member 5 is substantially flush with the front end surface of the outer case 22 in the vertical direction from the lower end edge of the outer case 22 to the lower end edge of the leg portion 12 of the article display shelf 10. As designed, it is designed to be covered. Thereby, the lower end edge of the cover member 5 is located below the lower end edge of the bottom plate 39 forming the machine room 32.

  The cover member 5 is designed such that the front end surface and the front end surfaces of the side plates 51, 51 are substantially flush with each other in the left-right direction.

  With these configurations, the front end surface of the base 3 is formed with substantially the same surface in the vertical direction, so that the aesthetics are good.

  Further, the cover member 5 is extended portions 5a and 5b formed by extending the lower end portions of both side end portions outward, and the height dimension T1 of the extended portions 5a and 5b is determined by the article display shelf 10. The leg portion 12 is formed to have substantially the same dimension (T1 = T2) as the height dimension T2. Thereby, the frozen / refrigerated showcase 1 is installed in the installation space S with the cover member 5 attached, so that the upper and lower edges of the extending portions 5a and 5b and the upper and lower edges of the leg portions 12 and 12 are horizontal. It is designed to form substantially the same plane in the direction.

  The lateral dimension W7 in the left-right direction of the extending portions 5a, 5b of the cover member 5 is the maximum width of the freezing / refrigerating showcase 1, and the lateral dimensions of the support columns 11, 11 and the leg portions 12, 12 in the lateral direction. It is formed to have substantially the same dimension slightly shorter than W6 (W7 <W6), and is longer than the inner dimension W4 in the left-right direction of the columns 11, 11 (W7> W4). The outside dimension W7 is substantially the same as the outside dimension W5 (W7 = W5).

  Further, since the front end surface of the cover member 5 and the front end surfaces of the side plates 51, 51 form substantially the same surface in the left-right direction, the side plates 51, 51 abut against the columns 11, 11 of the article display shelf 10. When the freezer / refrigerated showcase 1 is arranged in the installation space S, the cover member 5 forms substantially the same plane in the left-right direction as the kick plate 13.

  In addition, the extended portions 5a and 5b of the cover member 5 have an outside dimension W7 and are slightly shorter than the center dimension W6 in the left-right direction of the support columns 11 and 11, so that the freezing / refrigeration showcase 1 together with the kick plate 13 is provided.
