Brief Description of Drawings

[0007] [Figure 1]Perspective view of the cooling storage unit in Embodiment 1 [Figure 2] Side cross-sectional view of the cooling storage unit in Embodiment 1 [Figure 3] Perspective view showing a flip-up door in Embodiment 1 [Figure 4] Exploded perspective view of the guide mechanism in Embodiment 1 [Modes for carrying out the invention]

[0008] (Knowledge and other information that formed the basis of this disclosure) At the time the inventors conceived of this disclosure, a cooling storage unit was known that had a heated door and whose axis of rotation during door opening and closing was vertical. These cooling storage units used a technique that prevented wire breakage by providing a special hinge to run wiring through the axis of rotation during opening and closing. However, when the axis of rotation during door opening and closing is horizontal, it is necessary to provide a spring or damper to reduce the weight of opening and closing the door relative to the axis of rotation, so the same conventional structure as when the axis of rotation is vertical could not be applied. In other words, when the axis of rotation during door opening and closing is horizontal, it was not possible to align the wiring with the axis of rotation, and the inventors discovered a problem that there was a concern that the wiring would break due to bending caused by opening and closing the door, and in order to solve this problem, the subject matter of this disclosure was established. Therefore, this disclosure provides a cooling storage unit in which bending of the wiring is suppressed and wiring breakage is suppressed by aligning the orientation of the wiring with the axis of rotation.

[0009] The embodiments will be described in detail below with reference to the drawings. However, some unnecessarily detailed explanations may be omitted. For example, detailed explanations of already well-known matters or redundant explanations of substantially identical configurations may be omitted. The attached drawings and the following description are provided to enable those skilled in the art to fully understand this disclosure and are not intended to limit the subject matter described in the claims.

[0010] In each diagram, the forward, left, and upward directions refer to the side where the user's customers stand, with the rear being the side where the user of the refrigerated storage unit stands.

[0011] (Embodiment 1) [1-1. Structure] [1-1-1. Configuration of the Cooling Storage Facility] Figure 1 is a perspective view of the cooling storage unit 1 in Embodiment 1. Figure 2 is a side cross-sectional view of the cooling storage unit 1. In Figure 2, arrow S1 indicates the airflow in the cooling duct 21 generated by the operation of the cooling fan 23. Arrow S2 indicates the airflow in the machine room 40 generated by the operation of the blower fan 43.

[0012] The refrigerated storage unit 1 in this embodiment is a flat-type refrigerated storage unit that displays products while freezing them. The cooling storage unit 1 comprises a cooling storage unit body 5 and a hinged door 12. The cooling storage unit 1 is rectangular in plan view, and the cooling storage unit body 5 comprises a box-shaped enclosure 10 with an internal space. An opening 11 that opens upward is formed on the top surface of the cooling storage unit body 5. The cooling storage unit body 5 supports the hinged door 12. Users of the cooling storage unit 1 can freely open and close the opening 11 using the hinged door 12. The housing 10 has an intake port 44 at the lower front, through which air flows into the machine room 40, which will be described later. Also, as shown in Figure 2, an exhaust port 45 is formed at the lower rear of the housing 10, through which air from the machine room 40 is exhausted.

[0013] The cooling storage unit body 5 is equipped with an insulated chamber 20. The insulated chamber 20 is a box-shaped body surrounded by insulated walls 19 and is located inside the housing 10.

[0014] A machine room 40 is provided below the insulated room 20. An exhaust duct 47 is provided between the housing 10 and the insulated room 20, in front of the insulated room 20. The machine room 40 houses a compressor (not shown), a condenser 42, and a blower fan 43.

[0015] The heat insulation chamber 20 comprises a display chamber 30, and a cooling duct 21 provided between the heat insulation wall 19 and the display chamber 30. The cooling duct 21 is provided along the heat insulation wall 19 across the side surface and the bottom surface of the display chamber 30. An evaporator 22 and a cooling fan 23 are arranged in the cooling duct 21. The evaporator 22 is connected to a compressor in a machine room 40 and a condenser 42 via a refrigerant pipe not shown in the figures, forming a cooling circuit. Cooled air circulates through the cooling duct 21.

[0016] The display chamber 30 according to the present embodiment has a substantially L-shape in a side view. The display chamber 30 has a deep rear display section 31 provided at a rear portion of the display chamber 30, and a shallow front display section 32 provided at a front portion of the display chamber 30. A space inside the cooling duct 21 below the front display section 32 is for arranging the cooling fan 23. Further, as shown in FIG. 1, the display chamber 30 is partitioned into four spaces in the left-right direction by partition plates 33.

[0017] An air outlet 24 for blowing out cooled air is formed at an upper front end of the cooling duct 21. An air inlet 25 for sucking in air blown out from the air outlet 24 is formed at an upper rear end of the cooling duct 21. An air inlet cover 26 is provided at the air inlet 25. The air inlet cover 26 is a flat metal plate formed with a plurality of vertically long rectangular holes arranged in the left-right direction.

[0018] FIG. 3 is a perspective view showing the flip-up door 12. The present embodiment exemplifies a configuration in which the flip-up door 12 includes a door section 13, and a hinge mechanism 50 is provided attached to the door section 13. The hinge mechanism 50 connects an upper front surface of the heat insulation wall 19 (one side surface of a cooled storage main body) and a front end section of the door section 13, and supports the flip-up door 12 such that the flip-up door 12 can be opened and closed up and down with the left-right direction as a rotation axis. A spring, a damper, or the like (not shown) is provided in the hinge mechanism 50, and serves to hold the flip-up door 12 at a specific position when a user opens the flip-up door 12. As shown in Figures 1 and 2, the hinge mechanism 50 is covered at the front and upper by the guide portion 51. The guide portion 51 is provided across the entire left-right direction (width direction) of the housing 10.

[0019] Each door section 13 has a transparent plate 15 such as glass, a rectangular frame 14 provided on the outer end of the transparent plate 15, and a gripping section 16 provided on the rear end (one end) of the frame 14. In other words, the user can grasp the gripping section 16 and open and close the hinged door 12 in the vertical direction.

[0020] A heater 17 is positioned inside the frame 14. Another heater 17 is also positioned in the transparent plate 15 (not shown). Power supply wiring 18 is connected to the heater 17. The power supply wiring 18 extends out of the frame 14 through a round hole 14a formed at the front end of the frame 14. The power supply wiring 18 is connected to an electrical box (not shown). Power is supplied to the heater 17 from the electrical box connected to the power supply via the power supply wiring 18. As a result, the heater 17 is energized and the door section 13 is heated. By heating the door section 13, the temperature difference with the outside air can be reduced. This prevents condensation from forming on the transparent plate 15 and prevents the transparent plate 15 from fogging up when the flip-up door 12 is closed.

[0021] The hinged doors 12 are formed to be openable and closable for each partitioned space in the display room 30. That is, the refrigerated storage unit 1 according to this embodiment has four hinged doors 12, as shown in Figure 1. Users of the refrigerated storage unit 1 can access the corresponding display room 30 by opening and closing each hinged door 12.

[0022] [1-1-2. Configuration of the guidance system] A guide mechanism 59 is provided in the center of the front (other) end of the frame 14. The guide mechanism 59 and the hinge mechanism 50 are arranged on the same surface of the cooling storage unit body 5. In this embodiment, the guide mechanism 59 and the hinge mechanism 50 are arranged on the front side of the cooling storage unit body 5. In this embodiment, the guide mechanism 59 is fixed to the center of the front (other) end of the frame 14 and connects the upper front of the insulation wall 19 to the front end of the door 13.

[0023] Figure 4 is an exploded perspective view of the guide mechanism 59. The guide mechanism 59 consists of a first fitting 60 fixed to the front end of the frame 14 of the door section 13, a second fitting 70 fixed to the upper front of the insulated wall 19, and a guide tube 80 that supports the wiring 18 between the first fitting 60 and the second fitting 70.

[0024] The first fitting 60 has a stepped first fitting body 61. More specifically, the first fitting body 61 has a first upper wing 62 extending along the front end surface of the frame 14 of the hinged door 12, a first middle wing 63 extending from the lower end of the first upper wing 62 bent approximately vertically forward, and a first lower wing 64 extending from the front end of the first middle wing 63 bent approximately vertically downward. Two first upper vanes 62 are formed with a predetermined space S between them. Wiring 18 is placed in this space S. Space S can be any space that can accommodate the wiring 18.

[0025] A first metal fitting support portion 65 is provided at the left end (one end) of the first lower wing 64, extending almost vertically forward. The first metal fitting support portion 65 has a connecting hole 66 that penetrates in the left-right direction (width direction), that is, in this embodiment where the axis of rotation when the swing-up door 12 is opened and closed is horizontal, the axis of rotation is horizontal.

[0026] The first upper wing 62 has a fastening hole 67 that penetrates in the front-to-back direction. That is, the first fitting 60 is fixed to the door portion 13 through the fastening hole 67 by a fastening member (not shown). The first lower blade 64 is provided with a wiring clip 68 to support the wiring 18. The wiring clip 68 has a vertical guide clip 68a with a semi-cylindrical vertical insertion hole 68a1 with the vertical direction as its axis, and a horizontal guide clip 68b with a semi-cylindrical horizontal insertion hole 68b1 with the left-right direction as its axis.

[0027] The vertical guide clip 68a is provided below the space S, and the horizontal guide clip 68b is provided on the horizontal extension of the connection hole 66. The vertical guide clip 68a is provided above the horizontal guide clip 68b. The vertical guide clip 68a and the horizontal guide clip 68b are adjacent to each other, but the horizontal guide clip 68b is provided in a position where it does not overlap with the vertical insertion hole 68a1 of the vertical guide clip 68a in a plan view, and the vertical guide clip 68a is provided in a position where it does not overlap with the horizontal insertion hole 68b1 of the horizontal guide clip 68b in a side view. This allows the wiring 18 to be securely fixed, reduces damage to the wiring 18 caused by opening and closing the flip-up door 12, and prevents the wiring 18 from breaking.

[0028] The second fitting 70 has a second front vane 71 that extends along the front surface of the cooling storage body 5, and a second fitting support portion 72 that extends substantially perpendicularly forward from the right end (other end) of the second front vane 71. The second fitting support portion 72 is provided with a second wiring support cylinder 73 that extends from the right side (other end face) of the second fitting support portion 72. The second wiring support cylinder 73 is a hollow cylindrical member with its axial direction in the left-right direction.

[0029] The second front wing 71 has fastening holes (not shown). That is, the second fitting 70 is fixed to the cooling storage body 5 through the fastening holes by fastening members (not shown). A wiring clip 74 with a vertical insertion hole 74a is provided at the lower end of the left side surface of the second metal fitting support portion 72.

[0030] The guide tube 80 is a connector that positions the first fitting 60 and the second fitting 70. The guide tube 80 is composed of a first cylindrical portion 81, which has an outer diameter approximately the same as the diameter of the connection hole 66 of the first fitting support portion 65, and a second cylindrical portion 82, which has a larger outer diameter than the first cylindrical portion 81. The inner diameters of the first cylindrical portion 81 and the second cylindrical portion 82 are approximately the same as the outer diameter of the second wiring support tube 73.

[0031] As a result, by fitting the guide tube 80 into the second wiring support tube 73 and passing the first cylindrical portion 81 through the connection hole 66, the first fitting 60 and the second fitting 70 can be rotatably positioned in predetermined locations. In other words, in this embodiment, the axis of the connection hole 66 of the first metal fitting support part 65, the axis of the guide tube 80, and the axis of the second wiring support tube 73 are all coaxial. Furthermore, these axes are also coaxial with the rotation axis of the flip-up door 12.

[0032] The power supply wiring 18 extending from the heater 17 is supported by the wiring clip 68 of the first fitting 60, passes through the connection hole 66, the guide tube 80, and the second wiring support tube 73, and is supported by the wiring clip 74 of the second fitting 70.

[0033] [1-2. Operation, effect] [1-2-1. Operation and function of the guidance mechanism] The guide mechanism 59 supports the power supply wiring 18 on the rotation axis of the flip-up door 12, thereby suppressing the bending of the wiring 18 when the flip-up door 12 is opened and closed. Specifically, the stepped structure of the first fitting 60 guides the power supply wiring 18 onto the rotation axis, and the connection hole 66, guide tube 80, and second wiring support tube 73 support the power supply wiring 18 so that it extends along the rotation axis. By aligning the orientation of the wiring 18 with the rotation axis in this way, the power supply wiring 18 moves along the rotation axis when the flip-up door 12 is opened and closed.

[0034] Furthermore, since the first fitting 60 is supported by the hinged door 12, the fixed side of the fitting relative to the hinged door 12 moves around the axis of rotation as the hinged door 12 opens and closes. At this time, the position of the power supply wiring 18 is also determined according to the first fitting 60. Therefore, the portion of the wiring 18 extending from the hinged door 12 to the axis of rotation also moves together with the first fitting 60 in accordance with the opening and closing of the hinged door 12, and bending is suppressed.

[0035] [1-3. Effects, etc.] As described above, according to this embodiment, the cooling storage unit 1 comprises a cooling storage unit body 5, a display room 30 provided inside the cooling storage unit body 5 and opening upward, a hinged door 12 that opens and closes the opening of the display room 30 and has a heater 17, and wiring 18 connected to the heater 17, and has a hinge mechanism 50 arranged on one side of the cooling storage unit body 5 that allows the hinged door 12 to be opened and closed in the vertical direction, and a guide mechanism 59 arranged on the same side that guides the wiring 18 along the direction of the rotation axis of the hinge mechanism 50. According to this, by aligning the orientation of the wiring 18 with the axis of rotation, bending of the wiring 18 can be suppressed, and the breakage of the wiring 18 can be suppressed.

[0036] The guide mechanism 59 includes a first fitting 60 fixed to the hinged door 12, the first fitting 60 supporting a guide tube 80 that guides the wiring 18 along the direction of the rotation axis of the hinge mechanism 50. According to this, by placing the movable part of the wiring 18 on the axis of rotation, bending of the wiring 18 is suppressed, and the breakage of the wiring 18 can be suppressed.

[0037] The guide mechanism 59 includes a first fitting 60 fixed to the cooling storage body 5, and the first fitting 60 may be configured to support a guide tube 80 that guides the wiring 18 along the direction of the rotation axis of the hinge mechanism 50. According to this, by aligning the orientation of the wiring 18 with the axis of rotation, bending of the wiring 18 can be suppressed, and the breakage of the wiring 18 can be suppressed.

[0038] The first fitting 60 includes a vertical guide clip 68a with a vertical insertion hole 68a1 oriented vertically, and a horizontal guide clip 68b with a horizontal insertion hole 68b1 oriented horizontally. According to this, the wiring 18 can be held in the vertical insertion hole 68a1 and the horizontal insertion hole 68b1, so even when the flip-up door 12 is opened and closed, the wiring 18 can be prevented from separating from the first fitting 60 and the bending of the wiring 18 can be prevented.

[0039] The guide mechanism 59 further includes a second fitting 70 which is fixed to the cooling storage unit body 5 or the hinged door 12, and the second fitting 70 supports the guide tube 80. According to this, by providing the second fitting 70, bending of the wiring 18 can be suppressed more stably, and disconnection of the wiring 18 can be suppressed.

[0040] The first fitting 60 has a first fitting support portion 65 that is provided perpendicular to the guide tube 80 and supports the guide tube 80, and the second fitting 70 has a second fitting support portion 72 that is provided perpendicular to the guide tube 80 and supports the guide tube 80, and the first fitting support portion 75 and the second fitting support portion 72 may be in contact with each other. According to this, bending of the wiring 18 can be suppressed more stably, and disconnection of the wiring 18 can be suppressed.

[0041] The hinge mechanism 50 consists of a pair, and the guide mechanism 59 is positioned between the pair of hinge mechanisms 50. According to this, the guide mechanism 59 and the hinge mechanism 50 do not interfere with each other, and it is easy to align the wiring 18 with the axis of rotation.

[0042] (Other embodiments) As described above, Embodiment 1 has been presented as an example disclosed in this application. However, the technology in this disclosure is not limited to this and can be applied to embodiments that have been modified, replaced, added, or omitted. Furthermore, it is possible to create new embodiments by combining the components described in Embodiment 1. Therefore, other embodiments are illustrated below.

[0043] In the embodiment described above, the length of the guide tube 80 in the direction of rotation is not particularly limited and can be changed as needed.

[0044] In the embodiment described above, the first fitting 60 was provided on the hinged door 12, and the second fitting 70 was provided on the cooling storage unit body 5. However, both the first fitting 60 and the second fitting may be provided on the hinged door 12 side. Alternatively, both the first fitting 60 and the second fitting 70 may be provided on the cooling storage unit body 5 side.

[0045] In other words, the guide mechanism 59 may include a first fitting 60 fixed to the cooling storage body 5, and the first fitting 60 may support a guide tube 80 that guides the wiring 18 along the direction of the rotation axis of the hinge mechanism 50. Furthermore, the guide mechanism 59 may further include a second fitting 70 fixed to the flip-up door 12, and the second fitting 70 may support the guide tube 80.

[0046] In the embodiment described above, the guide mechanism 59 is composed of a first fitting 60, a guide tube 80, and a second fitting 70. However, the guide tube 80 can be omitted by arranging the second wiring support tube 73 to be directly inserted into the connection hole of the first fitting 60. Furthermore, by fixing the guide tube 80 to the main body of the cooling storage unit 5, the second fitting 70 can be omitted.

[0047] In the embodiment described above, the second wiring support tube 73 is inserted into the guide tube 80, and the first cylindrical portion 81 of the guide tube 80 is passed through the connection hole 66, thereby rotatably arranging the first fitting 60 and the second fitting 70 in predetermined positions. However, by not providing the second wiring support cylinder 73 in the second fitting support portion 72 and instead providing an insertion hole, the first cylindrical portion 81 of the guide cylinder 80 can be passed through the insertion hole and connection hole 66 of the second fitting support portion 72, thereby allowing the first fitting 60 and the second fitting 70 to be rotatably positioned at a predetermined location.
