DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a product storage device according to the present invention will be described in detail below with reference to the accompanying drawings.

[0013] 1 to 3 respectively show a product storage device according to an embodiment of the present invention, with Figs. 1 and 2 being perspective views showing the external configuration, and Fig. 3 being a cross-sectional side view showing a schematic diagram of the internal structure.

[0014] The product storage device 1 illustrated here is a so-called reach-in showcase that cools and keeps stored products, and includes a device main body 2.

[0015] The device main body 2 has a rectangular shape having a front opening 2A on the front side and a rear opening 2B on the rear side, and the front opening 2A is opened and closed by multiple (four in the illustrated example) front doors 3A, and the rear opening 2B is opened and closed by multiple (four in the illustrated example) rear doors 3B.

[0016] Inside the device main body 2, a machine chamber 4 located below the front opening 2A and the rear opening 2B and a product storage area 5 with a thermally insulated structure located above the machine chamber 4 are separated from each other.

[0017] The product storage area 5 is divided into a front area 7A and a rear area 7B by disposing a partition member 6 in the center in the front-rear direction. A front display chamber 10A and a front ventilation passage 20A are formed in the front area 7A.

[0018] The front display room 10A is a room defined in a manner facing the front opening 2A. In this embodiment, the inside of the front display room 10A is divided into four parts in the left-right direction corresponding to the four front doors 3A, but since each part has the same configuration, only one of them will be described.

[0019] In the front display room 10A, a plurality of (five in the illustrated example) front product storage shelves 11A are arranged in a vertical line in a plurality of tiers. These front product storage shelves 11A are configured by supporting flat shelf boards 112A so as to be spanned by a pair of left and right bracket members 111A engaged with shelf columns 12A erected in a pair on the left and right sides at the rear side of the front display room 10A.

[0020] That is, the front product storage shelf 11A is disposed by engaging the bracket member 111A with the shelf column 12A, and products are placed on the upper surface of the shelf board 112A. A front deck 13A is provided at the bottom of the front display room 10A. The front deck 13A is for placing products, similar to the front product storage shelf 11A.

[0021] The front ventilation passage 20A is formed inside the front area 7A and outside the front display chamber 10A, and is an air passage from the front intake port 14A to the front outlet port 15A. The front intake port 14A is an opening for sucking in air inside the front display chamber 10A, and is elongated and provided to extend along the left-right direction. The front intake port 14A is formed at the lower front edge of the front display chamber 10A, i.e., the lower edge of the front opening 2A.

[0022] The front air outlet 15A is an opening for blowing air into the front display chamber 10A. The front air outlet 15A is provided to extend along the left-right direction and is provided at the upper front edge of the front display chamber 10A, i.e., the upper edge of the front opening 2A.

[0023] Such a forward ventilation passage 20A comprises a front lower ventilation duct 21A located below and outside the front display room 10A, a front rear ventilation duct 22A located on the rear side and outside the front display room 10A, and a front upper ventilation duct 23A located above and outside the front display room 10A, and these front lower ventilation duct 21A, front rear ventilation duct 22A and front upper ventilation duct 23A are configured to be connected to each other.

[0024] A blower fan and a front evaporator 24A (not shown) are installed inside the front ventilation passage 20A. The blower fan circulates air. In the above-mentioned product storage device 1, when the blower fan is driven, air is sucked into the front ventilation passage 20A through the front intake port 14A and sent to the front outlet port 15A, and then blown out from the front outlet port 15A into the front display chamber 10A, thereby circulating air between the front display chamber 10A and the front ventilation passage 20A.

[0025] The forward evaporator 24A is connected by a refrigerant pipe to a refrigeration unit 30 that is configured with a compressor 31, a condenser 32, and an electronic expansion valve 33 disposed in the machine room 4, thereby forming a refrigerant circuit that circulates the refrigerant. Here, the compressor 31 sucks in, compresses, and discharges the refrigerant. The condenser 32 condenses the refrigerant compressed by the compressor 31. The electronic expansion valve 33 adiabatically expands the refrigerant condensed by the condenser 32.

[0026] The forward evaporator 24A exchanges heat between the refrigerant supplied thereto and the air passing through the forward ventilation passage 20A by driving the blower fan, more specifically, it cools the air passing through the forward ventilation passage 20A by evaporating the refrigerant. This cools the products in the forward display room 10A, i.e., the products placed on the forward product placement shelf 11A and the forward deck 13A.

[0027] In the rear area 7B, a rear display room 10B and a rear ventilation passage 20B are formed. The rear display room 10B is a room defined in a manner facing the rear opening 2B. In this embodiment, the interior of the rear display room 10B is divided into four parts in the left-right direction corresponding to the four rear doors 3B, but since each part has the same configuration, only one of them will be described.

[0028] In the rear display room 10B, a plurality of (five in the illustrated example) rear product storage shelves 11B are arranged in a vertical direction in multiple tiers. These rear product storage shelves 11B are configured by supporting flat shelf boards 112B so as to be spanned by a pair of left and right bracket members 111B engaged with shelf columns 12B erected in a pair on the left and right sides at the rear side of the rear display room 10B.

[0029] That is, the rear product storage shelf 11B is disposed by engaging the bracket members 111B with the shelf columns 12B, and products are placed on the upper surfaces of the shelves 112B. A rear deck 13B is provided at the bottom of the rear display room 10B. The rear deck 13B is for placing products, similar to the rear product storage shelf 11B.

[0030] The rear ventilation passage 20B is formed inside the rear area 7B and outside the rear display chamber 10B, and is an air passage from the rear intake port 14B to the rear outlet port 15B. The rear intake port 14B is an opening for sucking in air inside the rear display chamber 10B, and is elongated and extends in the left-right direction. The rear intake port 14B is formed at the lower rear edge of the rear display chamber 10B, i.e., at the lower edge of the rear opening 2B.

[0031] The rear air outlet 15B is an opening for blowing air into the rear display chamber 10B. The rear air outlet 15B is provided to extend along the left-right direction and is provided at the upper rear edge of the rear display chamber 10B, i.e., at the upper edge of the rear opening 2B.

[0032] Such a rear ventilation passage 20B comprises a rear lower ventilation duct 21B located below and outside the rear display room 10B, a rear rear side ventilation duct 22B located on the rear side and outside the rear display room 10B, and a rear upper ventilation duct 23B located above and outside the rear display room 10B, and these rear lower ventilation duct 21B, rear rear side ventilation duct 22B and rear upper ventilation duct 23B are configured to be connected to each other.

[0033] A blower fan and a rear evaporator 24B (not shown) are installed inside the rear ventilation passage 20B. The blower fan circulates air. In the above-mentioned product storage device 1, when the blower fan is driven, air is sucked into the rear ventilation passage 20B through the rear intake port 14B and sent to the rear outlet 15B, and then blown out from the rear outlet 15B into the rear display room 10B, thereby circulating air between the rear display room 10B and the rear ventilation passage 20B.

[0034] The rear evaporator 24B is connected to the refrigeration unit 30 through a refrigerant pipe to form a refrigerant circuit that circulates the refrigerant. The rear evaporator 24B exchanges heat between the refrigerant supplied to itself and the air passing through the rear ventilation passage 20B by driving the blower fan, and more specifically, cools the air passing through the rear ventilation passage 20B by evaporating the refrigerant. This cools the products in the rear display room 10B, i.e., the products placed on the rear product placement shelf 11B and the rear deck 13B.

[0035] The partition member 6 is composed of a first partition plate portion 6a and a second partition plate portion 6b. The first partition plate portion 6a is in the form of a long flat plate with the left-right direction being the longitudinal direction, and is erected at the bottom portion of the product storage area 5 in the device main body 2. More specifically, the first partition plate portion 6a is disposed in a manner to separate the front lower ventilation duct 21A and the rear lower ventilation duct 21B.

[0036] The second partition plate portion 6b has a flat plate shape whose left-right dimension is the same as that of the first partition plate portion 6a and whose up-down dimension is larger than that of the first partition plate portion 6a. The second partition plate portion 6b is disposed above the first partition plate portion 6a by having its lower surface placed on the upper surface of the first partition plate portion 6a and supported by a support member (not shown).

[0037] The front evaporator 24A and the rear evaporator 24B are attached to the first partition plate portion 6a in advance by fixing respective mounting plates (not shown) to both sides of the first partition plate portion 6a with screws, and are disposed at the same time when the first partition plate portion 6a is disposed at the bottom portion of the product storage area 5. The front evaporator 24A and the rear evaporator 24B are connected to the freezing unit 30 by, for example, brazing, with refrigerant inlet pipes 25A, 25B for introducing the refrigerant and refrigerant outlet pipes 26A, 26B for delivering the refrigerant being shared midway.

[0038] Explaining in more detail, as shown in FIG. 4, the refrigerant inlet pipe 25A connected to the front evaporator 24A passes through a through hole (not shown) formed in the first partition plate portion 6a and is connected to the refrigerant inlet pipe 25B connected to the rear evaporator 24B, and the refrigerant delivery pipe 26A connected to the front evaporator 24A passes through the above-mentioned through hole and is connected to the refrigerant delivery pipe 26B connected to the rear evaporator 24B.

[0039] As described above, according to the product storage device 1 of the embodiment of the present invention, the front evaporator 24A and the rear evaporator 24B are disposed in the device body 2 in a state of being attached to the first partition plate portion 6a in advance, so that the relative positional relationship between the front evaporator 24A and the rear evaporator 24B can be maintained at a constant size, and distortion, etc., can be suppressed in the refrigerant introduction pipes 25A, 25B and the refrigerant delivery pipes 26A, 26B, which are the pipes connected to the front evaporator 24A and the rear evaporator 24B, during the assembly work of the product storage device 1. Damage to the pipes connected to the front evaporator 24A and the rear evaporator 24B and the occurrence of refrigerant leakage, etc. can be prevented.

[0040] Moreover, since the front evaporator 24A and the rear evaporator 24B have the refrigerant introduction pipes 25A, 25B and the refrigerant delivery pipes 26A, 26B that are respectively commonized midway and connected to the refrigeration unit 30 by, for example, brazing, the connections between the multiple evaporators (24A, 24B) and the refrigeration unit 30 can also be commonized, making assembly easier. In particular, if the commonized portion of the refrigerant introduction pipes 25A, 25B and the commonized portion of the refrigerant delivery pipes 26A, 26B are connected to the refrigeration unit 30 through a common hole, leakage of cold air, drain water, and the like can be effectively suppressed.

[0041] According to the above-mentioned product storage device 1, the partition member 6 is composed of the first partition plate portion 6a and the second partition plate portion 6b, and the front evaporator 24A and the rear evaporator 24B are attached to the first partition plate portion 6a in advance, so that the front evaporator 24A and the rear evaporator 24B can be transported smoothly. Moreover, since the front evaporator 24A and the rear evaporator 24B are attached to the first partition plate portion 6a constituting the partition member 6 in advance, there is no need for a dedicated member or the like for fixing and arranging the front evaporator 24A and the rear evaporator 24B. Therefore, it is possible to suppress an increase in the number of parts and an increase in manufacturing costs.

[0042] 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.

[0043] In the above-described embodiment, an example was given of a product storage device 1 in which the front opening 2A is opened and closed by the front door 3A and the rear opening 2B is opened and closed by the rear door 3B, but in the present invention, the front opening and the rear opening may be ones that are always open.

[0044] In the above-described embodiment, the partition member 6 divides the product storage area 5 of the device main body 2 into a front area 7A and a rear area 7B, but in the present invention, the partition member may divide the product storage area into three or more areas.

[0045] In the above-described embodiment, the front evaporator 24A and the rear evaporator 24B were pre-attached to the first partition plate portion 6a, but in the present invention, the partition member may be constructed as a single unit, and multiple evaporators may be pre-attached to the partition member.
