DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the merchandise storage device according to the present invention will be described in detail.

[0011] FIGS. 1 to 3 show a merchandise storage device according to an embodiment of the present invention. FIGS. 1 and 2 are perspective views showing the external configuration, and FIG. 3 is a cross-sectional side view schematically showing the internal structure.

[0012] The merchandise storage device 1 illustrated here is for cooling and holding merchandise to be stored, such as what is called a reach-in showcase, and includes a device main body 2. The device main body 2 has a rectangular shape with a front opening 2A in the front and a rear opening 2B in the rear. A frame 40 described later is provided in the front opening 2A and the rear opening 2B.

[0013] Inside the device main body 2, a machine room 4 provided below the front opening 2A and the rear opening 2B and a merchandise storage area 5 with a heat insulation structure provided above the machine room 4 are partitioned from each other. In the merchandise storage area 5, a partition member 6 is arranged at the central portion in the front-rear direction, so that it is partitioned into a front area 7A and a rear area 7B. A front display room 10A and a front ventilation path 20A are formed in the front area 7A.

[0014] The front display room 10A is a room defined in a manner facing the front opening 2A. In the present embodiment, the inside of the front display room 10A is partitioned into four in the left-right direction. Since each configuration is the same, one of them will be described.

[0015] In the front display room 10A, a plurality (five in the illustrated example) of front product placement shelves 11A are arranged in a plurality of tiers along the vertical direction. These front product placement shelves 11A are supported by being configured such that a flat shelf board 112A is bridged over a pair of left and right bracket members 111A locked to shelf columns 12A standing in a left-right pair mode on the rear side of the front display room 10A.

[0016] That is, the front product placement shelf 11A is arranged by locking the bracket member 111A to 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 above-mentioned front product placement shelf 11A.

[0017] The front ventilation passage 20A is formed inside the front region 7A and outside the front display room 10A, and is a passage for air from the front suction port 14A to the front blowout port 15A. The front suction port 14A is an opening for sucking air inside the front display room 10A, and is a long-shaped one provided so as to extend along the left-right direction. This front suction port 14A is formed at the lower front edge of the front display room 10A, that is, the lower edge of the front opening 2A.

[0018] The front blowout port 15A is an opening for blowing air into the front display room 10A. This front blowout port 15A is provided so as to extend along the left-right direction, and is provided at the upper front edge of the front display room 10A, that is, the upper edge of the front opening 2A.

[0019] Such a front ventilation passage 20A includes a front lower ventilation duct 21A outside the front display room 10A and below it, a front rear-side ventilation duct 22A outside the front display room 10A and on its rear side, and a front upper ventilation duct 23A outside the front display room 10A and above it, and these front lower ventilation duct 21A, front rear-side ventilation duct 22A, and front upper ventilation duct 23A are configured to communicate with each other.

[0020] Inside such a front ventilation passage 20A, a blower fan (not shown) and a front evaporator 24A are installed. The blower fan circulates air. In the above-described merchandise storage device 1, when the blower fan is driven, the air sucked into the front ventilation passage 20A through the front suction port 14A is sent to the front blowout port 15A and blown out from the front blowout port 15A into the front display chamber 10A, thereby circulating air between the front display chamber 10A and the front ventilation passage 20A.

[0021] The front evaporator 24A is connected by a refrigerant pipe to a refrigeration unit 30 composed of a compressor 31, a condenser 32, and an electronic expansion valve 33 disposed in the machine room 4, thereby forming a refrigerant circuit for circulating refrigerant. Here, the compressor 31 sucks, 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.

[0022] The above-described front evaporator 24A exchanges heat between the refrigerant supplied to itself and the air passing through the front ventilation passage 20A when the blower fan is driven. More specifically, it cools the air passing through the front ventilation passage 20A by evaporating the refrigerant. Thereby, the merchandise in the front display chamber 10A, that is, the merchandise placed on the front merchandise placement shelf 11A and the front deck 13A, is cooled.

[0023] In the rear region 7B, a rear display chamber 10B and a rear ventilation passage 20B are formed. The rear display chamber 10B is a chamber defined in a manner facing the rear opening 2B. In the present embodiment, the interior of the rear display chamber 10B is divided into four in the left-right direction in the same manner as the front display chamber 10A, but since the respective configurations are the same, one of them will be described.

[0024] In the rear display room 10B, a plurality (five in the illustrated example) of rear product placement shelves 11B are arranged in a plurality of tiers along the vertical direction. These rear product placement shelves 11B are supported by being configured such that a flat shelf board 112B is bridged over a pair of left and right bracket members 111B locked to shelf columns 12B standing in a left-right pair mode on the rear side of the rear display room 10B.

[0025] That is, the rear product placement shelf 11B is arranged by locking the bracket member 111B to the shelf column 12B, and products are placed on the upper surface of the shelf board 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 above-mentioned rear product placement shelf 11B.

[0026] The rear ventilation passage 20B is formed inside the rear area 7B and outside the rear display room 10B, and is a passage for air from the rear suction port 14B to the rear blowout port 15B. The rear suction port 14B is an opening for sucking air inside the rear display room 10B, and is a long-shaped one provided to extend along the left-right direction. This rear suction port 14B is formed at the lower rear edge of the rear display room 10B, that is, the lower edge of the rear surface opening 2B.

[0027] The rear blowout port 15B is an opening for blowing air into the rear display room 10B. This rear blowout port 15B is provided to extend along the left-right direction, and is provided at the upper rear edge of the rear display room 10B, that is, the upper edge of the rear surface opening 2B.

[0028] Such a rear ventilation passage 20B includes a rear lower ventilation duct 21B outside the rear display room 10B and below it, a rear rear-side ventilation duct 22B outside the rear display room 10B and on its back side, and a rear upper ventilation duct 23B outside the rear display room 10B and above it, and these rear lower ventilation duct 21B, rear rear-side ventilation duct 22B, and rear upper ventilation duct 23B communicate with each other.

[0029] Inside such a rear ventilation passage 20B, a blower fan (not shown) and a rear evaporator 24B are installed. The blower fan circulates air. In the above-described merchandise storage device 1, when the blower fan is driven, the air sucked into the rear ventilation passage 20B through the rear suction port 14B is sent to the rear blowout port 15B and blown out from the rear blowout port 15B into the rear display chamber 10B, thereby circulating air between the rear display chamber 10B and the rear ventilation passage 20B.

[0030] The rear evaporator 24B is connected to the refrigeration unit 30 by a refrigerant pipe to form a refrigerant circuit for circulating refrigerant. The rear evaporator 24B exchanges heat between the refrigerant supplied to itself and the air passing through the rear ventilation passage 20B when the blower fan is driven. More specifically, the rear evaporator 24B cools the air passing through the rear ventilation passage 20B by evaporating the refrigerant. Thereby, the merchandise in the rear display chamber 10B, that is, the merchandise placed on the rear merchandise placement shelf 11B and the rear deck 13B, is cooled.

[0031] FIG. 4 is an explanatory view showing the inside of the frame body 40 disposed at the front opening 2A as viewed from the front.

[0032] The frame body 40 is disposed not only at the front opening 2A but also at the rear opening 2B. The frame body 40 disposed at the rear opening 2B has the same basic configuration as the frame body 40 disposed at the front opening 2A, differing only in the front-rear direction and the left-right direction. Therefore, hereinafter, the description of the frame body 40 disposed at the rear opening 2B will be omitted, and only the frame body 40 disposed at the front opening 2A will be described.

[0033] The frame body 40 includes a base frame 40a and a plurality (three in the illustrated example) of intermediate frame members 46. The base frame 40a is formed by assembling an upper frame member 41, a lower frame member 42, and a pair of left and right vertical frame members 43, 44 into a four-sided frame, and has a rectangular opening base 45.

[0036] The intermediate frame members 46 are arranged to connect the upper frame member 41 and the lower frame member 42. These intermediate frame members 46 are arranged at equal intervals in the left - right direction, and divide the opening base 45 into a plurality (four in the illustrated example) of rectangular openings 47.

[0037] In such a frame body 40, a glass door 50 is provided in a manner of opening and closing each rectangular opening 47. As shown in FIG. 1 and the like, the glass door 50 is a door body formed by attaching a heat - insulating glass face material 55 to a frame body 50a formed by surrounding a top frame member 51, a bottom frame member 52, and a pair of left - right vertical frame members 53, 54 in a four - sided frame configuration in a manner of closing the opening of the frame body 50a.

[0038] By the way, the upper frame member 41, the lower frame member 42, the left - hand vertical frame member 43, the right - hand vertical frame member 44, and the intermediate frame members 46 that constitute the frame body 40 are formed with wiring grooves 48 inside them in a manner of communicating with each other as shown in FIG. 4, and such wiring grooves 48 are covered with a cover (not shown).

[0039] And, one heater 60 is laid in the frame body 40. The heater 60 is a heating means that generates heat when in an energized state. This heater 60 is laid inside the frame body 40 as follows.

[0040] As shown in FIG. 5, the heater 60 that has entered the interior of the lower frame member 42 from the notch portion 421 formed in the portion constituting the leftmost rectangular opening 47 in the lower frame member 42 crawls leftward along the wiring groove 48 of the lower frame member 42, and then crawls upward along the wiring groove 48 of the left vertical frame member 43, and then crawls rightward along the wiring groove 48 of the upper frame member 41.

[0041] As shown in FIG. 6, at the connection portion of each intermediate frame member 46 of the upper frame member 41, the heater 60 crawls downward along the wiring groove 48 on the upper left side of the intermediate frame member 46, and as shown in FIG. 7, it is folded back by the upper return groove portion 48a formed at the intermediate height position of the intermediate frame member 46 and then crawls upward along the wiring groove 48 on the upper right side of the intermediate frame member 46, and then crawls rightward along the wiring groove 48 of the upper frame member 41.

[0042] After crawling rightward along the wiring groove 48 of the upper frame member 41 while being folded back by the upper return groove portion 48a of all the intermediate frame members 46 in this way, the heater 60 crawls downward along the wiring groove 48 of the right vertical frame member 44, and then crawls leftward along the wiring groove 48 of the lower frame member 42.

[0043] As shown in FIG. 8, at the connection portion of each intermediate frame member 46 of the lower frame member 42, the heater 60 crawls upward along the wiring groove 48 on the lower right side of the intermediate frame member 46, and as shown in FIG. 7, it is folded back by the lower return groove portion 48b formed at the intermediate height position of the intermediate frame member 46 and then crawls downward along the wiring groove 48 on the lower left side of the intermediate frame member 46, and then crawls leftward along the wiring groove 48 of the lower frame member 42.

[0044] After crawling leftward along the wiring groove 48 of the lower frame member 42 while being folded back by the lower return groove portion 48b of all the intermediate frame members 46 in this way, the heater 60 protrudes outside the lower frame member 42 from the notch portion 421 as shown in FIG. 5.

[0045] In this way, one heater 60 is laid out in one stroke in the frame body 40 in a manner that surrounds each rectangular opening 47 by being folded back by each intermediate frame member 46.
