[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a showcase according to the present invention will be described in detail with reference to the accompanying drawings.

[0014] 1 and 2 are schematic diagrams showing a showcase according to an embodiment of the present invention, with Fig. 1 being a cross-sectional side view and Fig. 2 being a front view. The showcase 1 shown as an example here is used to store products in a store such as a supermarket or a convenience store, and is configured with a case body 10 and a door unit 30.

[0015] The case body 10 has a bottom surface 11, a rear surface 12, and a top surface 13, and a storage chamber 14 with an open front surface is defined in the area surrounded by the bottom surface 11, the rear surface 12, and the top surface 13. The case body 10 is also provided with an air passage 15 in a manner that separates it from the storage chamber 14. The storage chamber 14 is closed on both the left and right sides by side plates 14a (see FIG. 2).

[0016] The ventilation passages 15 are formed inside the bottom surface portion 11, the rear surface portion 12 and the top surface portion 13, and include a lower duct 15a, a rear surface duct 15b and an upper duct 15c.

[0017] The lower duct 15a is formed in a portion of the bottom surface portion 11 that is lower than the bottom surface plate 11a that constitutes the bottom surface of the storage chamber 14. An intake port 11b extending along the left-right direction is formed in the front end portion of the bottom surface plate 11a. In other words, the intake port 11b is an opening formed in the front lower portion of the storage chamber 14.

[0018] The rear duct 15b is formed in a portion of the rear portion 12 that is rearward of the rear plate 12a that constitutes the rear surface of the storage chamber 14. The lower end portion of this rear duct 15b communicates with the rear end portion of the lower duct 15a.

[0019] The upper duct 15c is formed in a portion of the top surface portion 13 that is above the top panel 13a that constitutes the top surface of the storage chamber 14. The rear end portion of this upper duct 15c communicates with the upper end portion of the rear duct 15b. An air outlet 13b extending along the left-right direction is formed in the front end portion of the top panel 13a. In other words, the air outlet 13b is an opening formed in the front upper portion of the storage chamber 14.

[0020] An evaporator 16 and a blower fan 17 are installed inside the ventilation passage 15. The evaporator 16 constitutes a refrigeration cycle together with a condensing unit (not shown) and exchanges heat with the air passing through the ventilation passage 15.

[0021] When the blower fan 17 is driven, it draws air into the ventilation passage 15 through the suction port 11b, sends it out to the outlet port 13b, and then blows it out from the outlet port 13b into the storage chamber 14, thereby circulating air between the storage chamber 14 and the ventilation passage 15.

[0022] In this showcase 1, when the condensing unit and the blower fan 17 are driven, the air that has passed through the evaporator 16 is circulated and supplied to the storage chamber 14 through the ventilation passage 15, so that the storage chamber 14 is maintained at the desired refrigeration temperature.

[0023] A plurality of product storage shelves 20 are provided vertically in the storage room 14. The product storage shelves 20 each include a bracket member 21 and a shelf board 22.

[0024] The bracket members 21 are a pair of left and right bracket members formed from sheet metal or the like, and are long members whose longitudinal direction is the front-rear direction. The bracket members 21 are formed so that the vertical dimension of the rear end is larger than the vertical dimension of the front end. The bracket members 21 are disposed facing forward from the shelf supports 18 by engaging their rear ends with the shelf supports 18 erected on both the left and right sides of the rear panel 12a. In the following description, for convenience, the direction in which the pair of left and right bracket members 21 are close to each other is also referred to as the inside, and the direction in which they are separated from each other is also referred to as the outside.

[0025] 3(a) and 3(b), an outer component 23a of a slide mechanism 23 is attached to the inner surface of the bracket member 21. The slide mechanism 23 is a conventionally known one, and allows an inner component 23b constituting the slide mechanism 23 to slide in the front-rear direction relative to the outer component 23a.

[0026] The shelf board 22 is rectangular in shape, with the upper surface forming a placement surface on which products are placed. The shelf board 22 has auxiliary members 22a, 22b formed on the lower surfaces of both the left and right sides. The auxiliary member 22a formed on the lower surface of the left side of the shelf board 22 has the inner component 23b of the slide mechanism 23 attached to the inner surface of the left bracket member 21 attached thereto, and the auxiliary member 22b formed on the lower surface of the right side has the inner component 23b of the slide mechanism 23 attached to the inner surface of the right bracket member 21 attached thereto. This allows the shelf board 22 to slide in the front-rear direction relative to the pair of left and right bracket members 21.

[0027] The door body unit 30 is configured to include a first support member 31, a second support member 32, and a door body 33. The first support member 31 is in the form of a flat plate, and its width dimension (left-right dimension) is large enough to bridge between the pair of left and right bracket members 21. In addition, the length dimension (front-rear dimension) of the first support member 31 is larger than the length dimension of the shelf board 22 of the product storage shelf 20 in the front-rear direction.

[0028] As shown in Fig. 4, such a first support member 31 is inserted from the front side into any product storage shelf 20 (the uppermost product storage shelf 20 in the illustrated example), and is erected with both left and right ends placed on support guides 24 provided on the inner surfaces of a pair of left and right bracket members 21, as shown in Fig. 3(a). This first support member 31 is detachably arranged and can be removed from the product storage shelf 20 by pulling it out forward from the state in which it is placed on the support guides 24.

[0029] The front end of the first support member 31 protrudes forward from the shelf board 22 (shelf board 22 in the state slid most rearward) of the product storage shelf 20 (the uppermost product storage shelf 20).

[0030] A first ventilation hole 31a is formed in the front end of the first support member 31, i.e., in the portion that protrudes forward from the shelf board 22 of the product mounting shelf 20. The first ventilation hole 31a has a rectangular elongated hole shape with the left-right direction as the longitudinal direction, and allows the passage of air blown out from the air outlet 13b.

[0031] In this embodiment, the first ventilation hole 31a is described as having a long rectangular shape, but in the present invention, the first ventilation hole may be provided in multiple places at a predetermined interval along the left-right direction at the front end of the first support member.

[0032] The second support member 32 is in the form of a flat plate, and its width dimension (left-right dimension) is large enough to bridge between the pair of left and right bracket members 21. In addition, the length dimension (front-rear dimension) of the second support member 32 is larger than the length dimension of the shelf board 22 of the product storage shelf 20 in the front-rear direction.

[0033] As shown in Fig. 4, such a second support member 32 is inserted from the front side into any product storage shelf 20 (the fourth product storage shelf from the top in the illustrated example) and is erected with both left and right ends placed on support guides 24 provided on the inner surfaces of a pair of left and right bracket members 21, as shown in Fig. 3(b). This second support member 32 is detachably arranged and can be removed from the product storage shelf 20 by pulling it out forward from the state in which it is placed on the support guides 24.

[0034] The front end of the second support member 32 protrudes forward from the shelf board 22 (shelf board 22 in the rearmost position) of the product storage shelf 20 (the fourth product storage shelf 20 from the top).

[0035] A second ventilation hole 32a is formed in the front end of the second support member 32, i.e., in the portion that protrudes forward from the shelf board 22 of the product mounting shelf 20. The second ventilation hole 32a has a rectangular elongated hole shape with the left-right direction as the longitudinal direction, and allows the air that has passed through the first ventilation hole 31a to pass toward the suction port 11b.

[0036] In this embodiment, the second ventilation hole 32a is described as having a long rectangular shape, but in the present invention, the second ventilation holes may be provided in multiple numbers at predetermined intervals along the left-right direction at the front end of the second support member.

[0037] The door bodies 33 are formed, for example, from a light-transmitting material, and are a pair of left and right doors arranged to straddle the front end of the first support member 31 and the front end of the second support member 32. That is, the left door body (hereinafter also referred to as the left door body) 33L has, at the left end portion, a left upper shaft portion 331a that protrudes upward from the upper end and a left lower shaft portion 331b that protrudes downward from the lower end, as shown in Fig. 2. The left upper shaft portion 331a and the left lower shaft portion 331b are formed on the same central axis and have the same outer diameter dimensions.

[0038] The left door body 33L swings in the front-to-rear direction around the central axis of the left upper shaft portion 331a and the left lower shaft portion 331b, with the left upper shaft portion 331a being inserted into a support hole (not shown) formed at the left end of the front end portion of the first support member 31, and the left lower shaft portion 331b being inserted into a support hole (not shown) formed at the left end of the front end portion of the second support member 32.

[0039] Such a left door body 33L can close the left half of the opening between the first support member 31 and the second support member 32 by swinging backward, and can open the left half by swinging forward.

[0040] The right door body (hereinafter also referred to as the right door body) 33R has, at the right end portion, a right upper shaft portion 332a that protrudes upward from the upper end and a right lower shaft portion 332b that protrudes downward from the lower end, as shown in Fig. 2. The right upper shaft portion 332a and the right lower shaft portion 332b are formed on the same central axis and have the same outer diameter dimension.

[0041] The right door body 33R swings in the front-to-rear direction around the central axis of the right upper shaft portion 332a and the right lower shaft portion 332b, with the right upper shaft portion 332a being inserted into a support hole (not shown) formed at the right end of the front end portion of the first support member 31, and the right lower shaft portion 332b being inserted into a support hole (not shown) formed at the right end of the front end portion of the second support member 32.

[0042] Such a right door body 33R can close the right half of the opening between the first support member 31 and the second support member 32 by swinging backward, and can open the right half by swinging forward.

[0043] In this way, the door body 33 is a double door that can swing between a closed state in which it closes the front area of ​​the shelf 22 arranged between the first support member 31 and the second support member 32, and an open state in which it opens the front area.

[0044] In the showcase 1 having the above-mentioned configuration, the door body unit 30 is attached by installing the first support member 31 and the second support member 32 between the bracket members 21 of any product placement shelf 20, thereby improving the degree of freedom in installing the door body 33. Moreover, the door body unit 30 can be easily attached by simply installing the first support member 31 and the second support member 32 between the bracket members 21. Moreover, the door body 33 can be swung between a closed state in which the front area of ​​the shelf board 22 arranged between the first support member 31 and the second support member 32 is closed, and an open state in which the front area is opened, so that it is possible to suppress the intrusion of outside air and the leakage of cold air while allowing the removal of products placed on the shelf board 22.

[0045] Therefore, according to the showcase 1, the door body 33 can be easily attached with a high degree of freedom, and power consumption can be reduced.

[0046] Furthermore, according to the above-mentioned showcase 1, the first ventilation hole 31a of the first support member 31 constituting the door body unit 30 allows the air blown out from the air outlet 13b to pass through, and the second ventilation hole 32a of the second support member 32 allows the air that has passed through the first ventilation hole 31a to pass toward the air inlet 11b. Therefore, the air blown out from the air outlet 13b (air cooled by the evaporator 16) can be actively caused to flow into the interior of the door body unit 30, and the first ventilation hole 31a and the second ventilation hole 32a also act as guides that guide the air blown out from the air outlet 13b to the air inlet 11b, thereby forming an air curtain well.

[0047] Furthermore, according to the showcase 1, the door body 33 constituting the door body unit 30 is made of a translucent material, so that even when the door body 33 is in a closed state blocking the front area of ​​the shelf board 22 between the first support member 31 and the second support member 32, the products placed on the shelf board 22 can be viewed from the outside.

[0048] Although the preferred embodiment of the present invention has been described above, the present invention is not limited to this and various modifications can be made.

[0049] Fig. 5 and Fig. 6 are schematic diagrams showing modified examples of the showcase 1 according to the embodiment of the present invention, Fig. 5 being a cross-sectional side view and Fig. 6 being a front view. Note that the same components as those in the showcase 1 according to the embodiment described above are given the same reference numerals and the description thereof will be omitted.

[0050] As shown in FIGS. 5 and 6, the showcase 2 may include a first slit curtain member 41 and a second slit curtain member 42 in addition to the door unit 30. As shown in FIG.

[0051] The first slit curtain member 41 is configured by hanging and supporting a first mounting rod-shaped body 41a extending in the left-right direction with a plurality of first rectangular sheets 41b aligned along the left-right direction. These first sheets 41b are made of a light-transmitting material and have flexibility. The vertical dimension of these first sheets 41b is such that when the first mounting rod-shaped body 41a is attached to the front end of the top surface portion 13 by, for example, magnetic force, the lower end portion can cover the front end surface of the first support member 31.

[0052] The second slit curtain member 42 is configured by hanging and supporting a plurality of rectangular second sheets 42b aligned along the left and right from a second mounting rod-shaped body 42a extending along the left and right direction. These second sheets 42b are made of a light-transmitting material and have flexibility. The vertical dimension of these second sheets 42b is such that when the second mounting rod-shaped body 42a is attached to the front end surface of the second support member 32 by, for example, magnetic force, the lower end portion can cover the fence 11c provided at the upper front end of the bottom surface portion 11.

[0053] According to such a showcase 2, the front area of ​​the shelf board 22 that is not closed by the door unit 30 can be covered, thereby suppressing the intrusion of outside air and the leakage of cold air, and reducing power consumption.

[0054] 7 is a cross-sectional side view showing a schematic diagram of another modified example of the showcase 1 according to the embodiment of the present invention. Note that the same components as those in the showcase 1 according to the embodiment described above are given the same reference numerals and the description thereof will be omitted.

[0055] 7, the showcase 3 includes a first door body unit 30a and a second door body unit 30b. The first door body unit 30a and the second door body unit 30b have the same configuration as the door body unit 30 except for the vertical dimensions, etc., and therefore detailed description thereof will be omitted.

[0056] The first door body unit 30a is removably attached in a manner to open and close the front area of ​​the shelf 22 of the second product storage shelf 20 from the top, and the second door body unit 30b is removably attached in a manner to open and close the front area of ​​the shelf 22 of the fourth product storage shelf 20 from the top and the bottommost shelf.

[0057] With such a showcase 3 as well, the door body 33 can be easily attached with a high degree of freedom, and power consumption can be reduced.

[0058] In the above-described embodiment, the door body 33 is supported by the first support member 31 and the second support member 32 in a swingable manner. However, as in the reference example showcase 4 shown in Figures 8 and 9, the front end portion of the bracket member 21a may be extended forward beyond the shelf board 22c, and the door body 50 may be supported by the front end surface thereof via a hinge mechanism 51 in a swingable manner.

[0059] In the above-described embodiment, the door body 33 is supported swingably by the first support member 31 and the second support member 32, but in the present invention, the door body may be supported slidably by the first support member and the second support member. In other words, the door body may be provided in any manner as long as it can be displaced between a closed state in which the front area of ​​the shelf board arranged between the first support member and the second support member is closed, and an open state in which the front area is opened.
