Summary of the Invention

Problems to be Solved by the Invention

[0004] In a configuration where a door covers the opening of a heat-insulating box body from above as in the above Patent Document 1, the packing is pressed against the heat-insulating box body side by the weight of the door. Further, the packing is configured to form a rectangular frame shape by four extended portions. In a configuration where the door is attached to the heat-insulating box body via a hinge member, in the extended portion of the packing close to the hinge member, since they are arranged in the order of the hinge member (fulcrum), the packing (point of application), and the center of gravity of the door (point of force), a strong pressing force acts on the packing according to the principle of the lever. However, in the extended portion of the packing far from the hinge member, since they are arranged in the order of the hinge member (fulcrum), the center of gravity of the door (point of force), and the packing (point of application), the pressing force becomes weaker compared to the extended portion close to the hinge member. As a result, there has been a problem that the sealing performance by the packing deteriorates.

[0005] The technology disclosed in this specification has been completed based on the above circumstances, and an object thereof is to provide a cooling storage cabinet capable of further improving the sealing performance of a storage chamber by packing.

Means for Solving the Problem

[0006] As a means for solving the above problems, the refrigerated storage disclosed in this specification includes a storage body that is a box body constituting a storage chamber having an opening opened upward, a door that covers the opening from above, and a hinge member that rotatably attaches the door to the storage body with an axis along the horizontal direction as a rotation axis. A packing provided on the surface of the door on the storage body side and interposed between the door and the opening end of the opening in the storage body, and a weight provided on the door. The hinge member is configured to connect the side end portion of the door on the hinge member side and the storage body. The packing is configured to form a frame shape by a plurality of extending portions. When the side end portion of the door opposite to the hinge member is a door tip portion, the weight includes at least a weight side extending portion disposed between the tip side extending portion, which is the extending portion closest to the door tip portion among the plurality of extending portions, and the door tip portion. The weight side extending portion has a longitudinal shape extending along the extending direction of the tip side extending portion, and is characterized in that the length of the weight side extending portion is equal to or greater than the length of the tip side extending portion.

[0007] Further, the door includes a main wall portion that covers the opening and a side wall portion that rises from the outer peripheral end portion of the main wall portion toward the storage body side. A door handle is provided on the surface of the first extending wall portion, which is a portion constituting the door tip portion in the side wall portion, on the side opposite to the hinge member. The weight is provided on the surface of the first extending wall portion on the hinge member side and can be co-fastened to the first extending wall portion by a fastening member together with the door handle.

Advantages of the Invention

Mode for Carrying Out the Invention

[0010] One embodiment of the present invention will be described with reference to FIGS. 1 to 13. In this embodiment, as a cooling storage, the deep freezer 10 is exemplified. As shown in FIG. 1, the deep freezer 10 is generally in the shape of a rectangular parallelepiped as a whole, and stores stored items in a cooled state in an ultra-low temperature range (for example, a temperature range of -40°C or lower, which is lower than the cooling temperature of a general cooling storage).

[0011] As shown in FIGS. 1 and 2, the deep freezer 10 includes a storage cabinet main body 11 which is a box body constituting a storage chamber 17 having an opening 16 (see FIG. 3) opened upward, a heat-insulating door 50 that covers the opening 16 from above, a hinge member 70 that rotatably attaches the door 50 to the storage cabinet main body 11 with a horizontal axis as a rotation axis R1, a lock mechanism 80 for locking the door 50, a machine room 15 disposed below the storage cabinet main body 11, and a cooling device 20 (see FIG. 5) for cooling the inside of the storage cabinet main body 11.

[0012] As shown in FIG. 4, the storage cabinet main body 11 is a heat-insulating box body having a structure in which a heat-insulating material 14 made of a foamed resin (such as a foamed urethane material or a melamine foam) is filled between an outer box 12 and an inner box 13. The outer box 12 and the inner box 13 are formed by assembling a metal plate such as stainless steel into a box shape. The internal space of the inner box 13 serves as the storage chamber 17 for storing items.

[0013] As shown in FIGS. 1 and 2, the machine room 15 is a space surrounded by panels 18A, 18B, 18C, 18D having ventilation holes 18E. The machine room 15 houses a compressor 24, an air-cooling fan 25, a control device 40, etc. that constitute the cooling device 20 (see FIG. 5, details will be described later). In FIGS. 1 and 2, the panels 18A and 18D are shown by a two-dot chain line. The control device 40 includes a circuit for controlling the operation of the deep freezer 10 and supplying power.

[0014] As shown in FIG. 5, the cooling device 20 includes a cooling pipe 21, a refrigerant pipe for the storage wall 22, a wire tube condenser 23, a compressor 24, an air-cooling fan 25, a drier 26, a heat exchanger 27, and a capillary tube 28. These are connected by a refrigerant pipe 30 (for example, a hollow pipe made of copper) and a refrigeration circuit (refrigeration cycle) is formed by circulating the refrigerant. For example, a mixed refrigerant (such as a mixed refrigerant of butane and ethylene) is used as the refrigerant to enhance the cooling capacity and lower the cooling temperature to about -50°C or lower. Also, a temperature sensor 35 (thermistor) is provided on the downstream side (outlet side, discharge side) of the refrigerant flow direction of the compressor 24 to detect abnormal high pressure of the refrigerant.

[0015] The compressor 24 sucks and compresses the refrigerant gas using a motor as a power source, and discharges the high-temperature and high-pressure refrigerant gas. The air-cooling fan 25 sucks in outside air and blows it toward the compressor 24, thereby air-cooling and protecting the compressor 24. Further, when the detected temperature of the temperature sensor 35 reaches a predetermined condition (for example, continuously detected at 150°C or higher for 10 minutes), the control device 40 stops the compressor 24 to protect it. The refrigerant gas compressed by the compressor 24 flows into the wire tube condenser 23.

[0016] As shown in FIG. 5, the wire tube condenser 23 includes a condenser tube 23A and a wire 23B. The condenser tube 23A is a long refrigerant tube having a meandering shape, and has a straight portion extending in the left-right direction and a folded-back portion (U-bend portion). The high-temperature and high-pressure refrigerant gas from the compressor 24 flows into the condenser tube 23A, and the refrigerant gas from the compressor 24 is liquefied by being cooled by contacting the outside air in the process of passing through the condenser tube 23A.

[0017] The wire 23B is a wire-shaped heat transfer member that extends in a direction intersecting the straight portion of the condenser tube 23A and is arranged in a plurality of rows at a predetermined interval. The wire 23B is welded to the surface of the condenser tube 23A. As shown in FIG. 2, the wire tube condenser 23 is provided on the back surface of the storage body 11. By providing the wire 23B, even when the wire tube condenser 23 is arranged so as to be exposed to the outside, it is possible to increase the heat transfer area and improve the condensation ability while suppressing deformation due to contact as compared with fins, which are more common heat transfer members.

[0018] As shown in Fig. 4, the refrigerant pipe 22 on the storage wall is provided along the inner surface of the outer box 12. As shown in Fig. 5, the refrigerant pipe 22 on the storage wall is provided on the downstream side (outlet side) of the refrigerant flow direction of the wire tube condenser 23 to suppress dew condensation on the outer surface of the outer box 12 of the storage body 11. The dryer 26 is provided on the downstream side (outlet side) of the refrigerant flow direction of the refrigerant pipe 22 on the storage wall to remove moisture mixed in the refrigerant liquid. A capillary tube 28 is provided on the downstream side (outlet side) of the refrigerant flow direction of the dryer 26 via a heat exchanger 27.

[0019] The capillary tube 28 is a capillary tube having a narrow flow path, and the refrigerant undergoes a pressure drop (throttling expansion) by passing through the capillary tube 28. A cooling pipe 21 is provided on the downstream side (outlet side) of the refrigerant flow direction of the capillary tube 28. As shown in Fig. 4, the cooling pipe 21 is provided along the outer surface of the inner box 13. The cooling pipe 21 vaporizes the refrigerant liquid depressurized by the capillary tube 28 to cool the storage chamber 17 by the heat of vaporization. The refrigerant gas flowing out of the cooling pipe 21 returns to the compressor 24 through the heat exchanger 27. The cooling operation of the deep freezer 10 is performed by the control device 40 operating the compressor 24 and the air-cooling fan 25.

[0020] As shown in Fig. 5, the heat exchanger 27 is provided to exchange heat between the refrigerant flowing from the cooling pipe 21 toward the compressor 24 (relatively low temperature because it is the refrigerant flowing out of the cooling pipe 21) and the refrigerant flowing from the dryer 26 toward the capillary tube 28 (relatively high temperature because it is the refrigerant flowing out of the wire tube condenser 23 side). Also, the capillary tube 28 is configured to exchange heat with the refrigerant flowing from the cooling pipe 21 toward the compressor 24.

[0021] As shown in Fig. 7, the door 50 includes a main wall portion 51 that covers the opening 16, and a frame-shaped side wall portion 52 that rises from the entire circumference of the outer peripheral end portion of the main wall portion 51 toward the storage chamber body 11 side. That is, the side wall portion 52 is composed of four extending wall portions 52D (see Fig. 6) having a longitudinal shape. The main wall portion 51 and the side wall portion 52 constitute an exterior plate, and are configured by bending a metal plate such as stainless steel. Further, the door 50 includes an interior plate 72 made of synthetic resin that mainly constitutes the surface on the storage chamber body 11 side. The internal space surrounded by the main wall portion 51, the side wall portion 52, and the interior plate 72 is filled with a heat insulating material (not shown) made of foamed resin (such as foamed urethane material, melamine foam, etc.).

[0022] As shown in Fig. 6, a square frame-shaped packing 53 is provided at the peripheral edge of the surface on the storage chamber body 11 side of the interior plate 72 (the surface on the storage chamber body side of the door). When the door 50 is closed, the packing 53 is interposed between the door 50 and the opening end portion 16A of the opening 16 in the storage chamber body 11 as shown in Fig. 7. Thereby, the storage chamber 17 is sealed. As shown in Fig. 3, the opening 16 has a square shape in plan view, and the opening end portion 16A has a square frame shape. For this reason, the packing 53 has a square frame shape that follows the shape of the opening end portion 16A, and is configured to abut against the entire circumference of the opening end portion 16A. The packing 53 is formed of an elastically deformable material such as a soft resin such as polyvinyl chloride or polyester, or rubber, but is not limited thereto.

[0023] More specifically, as shown in Fig. 6, the packing 53 is configured to form a square frame shape by four extending portions 54. As shown in Fig. 8, each extending portion 54 has a mounting portion 59 having a cross-sectional arrow shape. The mounting portion 59 is fitted into a groove portion 57 formed at the peripheral edge of the surface on the storage chamber body 11 side of the interior plate 72. As shown in Fig. 6, the door 50 has a square shape, and its center of gravity G1 is arranged at the center in the front-rear direction (the vertical direction in Fig. 6) and the left-right direction (the left-right direction in Fig. 6). That is, the center of gravity G1 of the door 50 is arranged inside the packing 53 in the plan view of Fig. 6.

[0024] As shown in FIG. 2, two hinge members 70 are arranged side by side along the left-right direction. Further, as shown in FIG. 7, the hinge member 70 is configured to connect the side end portion 50A on the hinge member 70 side of the door 50 and the upper end portion of the back surface of the storage body 11. Thereby, the door 50 is rotatable about the hinge pin 71 (rotation axis R1) of the hinge member 70. In the following description, the side end portion of the door 50 opposite to the hinge member 70 is referred to as the door tip portion 55.

[0025] When the extended wall portion 52D (the portion constituting the door tip portion in the side wall portion) that constitutes the door tip portion 55 among the four extended wall portions 52D that constitute the side wall portion 52 is defined as the first extended wall portion 52A, as shown in FIG. 7, a door handle 56 is provided on the surface of the first extended wall portion 52A opposite to the hinge member 70. Further, the lock mechanism 80 for locking the door 50 includes a door-side lock mechanism 81 attached to the door 50 and a main body-side lock mechanism 82 attached to the storage body 11. The door-side lock mechanism 81 is provided on the surface of the first extended wall portion 52A opposite to the hinge member 70 (the surface on which the door handle 56 is provided). The door 50 is configured to be locked when the door-side lock mechanism 81 and the main body-side lock mechanism 82 engage with each other.

[0026] As shown in Fig. 7, a weight 60 is provided on the surface of the first extended wall portion 52A on the hinge member 70 side. The weight 60 is, for example, a steel plate plated with zinc on the surface, and as shown in Fig. 9, includes a weight-side extended portion 61 formed in a long plate shape. As shown in Fig. 7, the weight-side extended portion 61 is disposed between the tip-side extended portion 54A, which is the extended portion closest to the door tip portion 55 among the plurality (four in this embodiment) of extended portions 54 constituting the packing 53, and the door tip portion 55. As shown in Fig. 9, the weight-side extended portion 61 extends in a longitudinal shape along the extending direction of the tip-side extended portion 54A. Further, the length L1 of the weight-side extended portion 61 in the extending direction is set to be equal to or greater than the length L2 of the tip-side extended portion 54A. The central axes of the tip-side extended portion 54A and the weight-side extended portion 61 in the length direction are arranged at the same position in the length direction (the left-right direction of the door 50). Thereby, the tip-side extended portion 54A can be uniformly pressed in the length direction by the weight-side extended portion 61.

[0027] As shown in Fig. 8, the weight 60 is fastened together with the door handle 56 to the first extended wall portion 52A by a fastening member 58 (for example, a mounting bolt). The door handle 56 has a housing space S1 in which one end portion (the head of the bolt) of the fastening member 58 is housed, and a through hole 56A is formed in the wall portion on the first extended wall portion 52A side that constitutes the housing space S1. Further, a through hole 52B is formed in the first extended wall portion 52A, and a through hole 60A is formed in the weight-side extended portion 61. The fastening member 58 is inserted through the through hole 56A, the through hole 52B, and the through hole 60A, and is screwed into female threads (not shown) formed on the inner surfaces of the respective through holes 56A, 52B, and 60A.

[0028] As shown in Fig. 10, a storage chamber temperature sensor 62 for measuring the temperature of the storage chamber 17 is provided in the storage chamber 17. The control device 40 (control unit) controls the operations of the compressor 24 and the air-cooling fan 25 based on the measured temperature of the storage chamber temperature sensor 62. The storage chamber temperature sensor 62 is arranged near the bottom surface of the storage chamber 17, and is arranged near a corner formed by two adjacent side wall portions 13A among the side wall portions 13A constituting the inner box 13. The storage chamber temperature sensor 62 is attached to one side wall portion 13A via a bracket 63. Thereby, the storage chamber temperature sensor 62 and the wiring 64 (described later) are arranged at a distance from each of the bottom wall portion 13E and the side wall portion 13A which are the inner surfaces of the inner box 13.

[0029] Also, as shown in Fig. 11, the storage chamber temperature sensor 62 is protected by being covered with a cover member 65 (not shown in Fig. 10). The cover member 65 includes a side wall portion 65A that covers the storage chamber temperature sensor 62 from the side, a triangular upper wall portion 65B that covers the storage chamber temperature sensor 62 from above, and flange portions 65D and 65E respectively provided at each side end portion of the side wall portion 65A. Notches 68 that are open downward are respectively formed at the lower portions of the flange portions 65D and 65E, and both flange portions 65D and 65E are respectively fixed to each side wall portion 13A by screws 67 inserted through the notches 68.

[0030] In addition, a plurality of long-hole-shaped ventilation holes 65F are formed in the side wall portion 65A of the cover member 65. The air in the space arranged outside the cover member 65 in the storage chamber 17 is taken into the internal space of the cover member 65 (the space around the storage chamber temperature sensor 62) through the ventilation holes 65F.

[0031] The temperature sensor 62 inside the storage is electrically connected to the control device 40 by wiring 64. As shown in FIG. 12, the wiring 64 is inserted into a through-hole 13B formed through the bottom wall portion 13E of the inner box 13. The through-hole 13B is formed by performing a flanging process on the bottom wall portion 13E. Thereby, a flange 13D rising upward is formed at the hole edge portion of the through-hole 13B. By providing such a flange 13D, when water accumulates on the bottom surface of the storage chamber 17, the situation where the water enters the through-hole 13B can be suppressed.

[0032] Also, in the wiring 64, the portion inserted into the through-hole 13B and its peripheral portion are covered by a coating member 69 having heat insulation, insulation, and waterproof properties. Further, a sealing material 66 is provided so as to cover the outer peripheral surfaces of the flange 13D and the coating member 69. Thereby, the situation where water falls below the bottom wall portion 13E through between the coating member 69 and the inner surface of the through-hole 13B can be suppressed. The temperature sensor 62 (and thus the cover member 65) inside the storage is arranged at a corner portion on the control device 40 side in the storage chamber 17 as shown in FIG. 4. Thereby, the temperature sensor 62 inside the storage can be arranged closer to the control device 40, and the wiring 64 can be made shorter.

[0033] Next, the effects of the present embodiment will be described. In the present embodiment, the door 50 is rotatably attached to the storage body 11 via a hinge member 70. And the packing 53 is pressed against the opening end portion of the opening 16 by the weight of the door 50. Here, as shown in FIG. 7, among the plurality of extended portions 54 constituting the packing 53, in the extended portion closest to the hinge member 70 (hereinafter referred to as the hinge-side extended portion 54B), since the rotation axis R1 (fulcrum), the hinge-side extended portion 54B (point of action), and the center of gravity G1 (point of force) of the door 50 are arranged in this order, a strong pressing force acts on the packing 53 according to the principle of a lever.

[0034] However, among the plurality of extended portions 54 that make up the packing 53, in the tip-side extended portion 54A, which is the extended portion closest to the door tip portion 55, since they are arranged in the order of the rotation axis R1 (fulcrum), the center of gravity G1 (effort point) of the door 50, and the tip-side extended portion 54A (point of application), the pressing force is weaker than that of the hinge-side extended portion 54B. Therefore, in the above configuration, in addition to the self-weight of the door 50, the packing 53 is pressed by the self-weight of the weight 60.

[0035] The weight-side extended portion 61 of the weight 60 is disposed between the tip-side extended portion 54A and the door tip portion 55. For this reason, since they are arranged in the order of the rotation axis R1 (fulcrum), the tip-side extended portion 54A (point of application), and the weight-side extended portion 61 (effort point), by the principle of the lever, a strong pressing force can be applied to the tip-side extended portion 54A.

[0036] Furthermore, the weight-side extended portion 61 has an elongated shape extending along the extending direction of the tip-side extended portion 54A, and its length L1 is set to be equal to or greater than the length L2 of the tip-side extended portion 54A. Thereby, the weight-side extended portion 61 can press the tip-side extended portion 54A over the entire length in the extending direction. From the above, it is possible to suppress a situation where a portion with weak pressing occurs in the packing 53, and the sealing performance of the storage chamber 17 by the packing 53 can be made higher.

[0037] Also, the door 50 includes a main wall portion 51 that covers the opening 16, and a side wall portion 52 that rises from the outer peripheral end portion of the main wall portion 51 toward the storage body 11 side. A door handle 56 is provided on the surface of the first extended wall portion 52A, which is the portion constituting the door tip portion 55 in the side wall portion 52, on the side opposite to the hinge member 70. The weight 60 is provided on the surface of the first extended wall portion 52A on the hinge member 70 side, and is jointly fastened to the first extended wall portion 52A by a fastening member 58 together with the door handle 56.

[0038] By attaching the weight 60 to the first extended wall portion 52A, the rigidity can be further increased. As a result, it is possible to suppress a situation in which the first extended wall portion 52A is deformed by the load when the operator grips the door handle 56 and opens and closes the door 50. Further, by providing the door handle 56 at the door tip portion 55 (the end portion far from the rotation axis R1), based on the lever principle, the operator can open and close the door 50 with a smaller force.

[0039] <Other Embodiments> The technology disclosed in this specification is not limited to the embodiments described by the above description and drawings. For example, the following embodiments are also included in the technical scope. (1) In the above embodiment, the weight 60 including only the weight-side extended portion 61 is exemplified, but the present invention is not limited to this. The weight only needs to include at least the weight-side extended portion 61, and its shape can be appropriately changed. For example, a weight 160 having a substantially U shape as shown in FIG. 13 may be used. The weight 160 includes a weight-side extended portion 61 extending along the first extended wall portion 52A, and a pair of side wall portions 162, 162 respectively rising from both end portions in the extending direction of the weight-side extended portion 61 toward the hinge member 70 side. The side wall portion 162 extends along the back surface of the extended wall portion 52D adjacent to the first extended wall portion 52A among the side wall portions 52. By providing such a side wall portion 162, the rigidity of the weight 160 can be further increased. (2) In the above embodiment, the opening end portion 16A of the opening 16 and the packing 53 having a square frame shape are exemplified, but the present invention is not limited to this. The packing only needs to be configured to form a frame shape by a plurality of extended portions, and may have a shape following the shape of the opening end portion at the opening of the storage chamber 17. For example, when the opening of the storage chamber 17 has a semi-circular shape, the packing only needs to have a semi-circular frame shape, and when the opening of the storage chamber 17 has a triangular shape, the packing only needs to have a triangular frame shape. (3) In the above embodiment, a mounting bolt is exemplified as the fastening member, but the present invention is not limited to this. The fastening member only needs to be configured to be able to co-fasten the door handle 56 and the weight 60 to the first extended wall portion 52A. (4) The installation locations of the control device 40 and the in - chamber temperature sensor 62 are not limited to those exemplified in the above - described embodiment. The installation location of the in - chamber temperature sensor 62 can be appropriately changed according to the installation location of the control device 40. In the storage chamber 17, it may be arranged at the corner closest to the control device 40. (5) In the above - described embodiment, the deep freezer 10 is exemplified as the cooling storage. However, it is not limited to this. However, the deep freezer 10 of the present embodiment cools the storage chamber 17 in an ultra - low temperature range. For this reason, when outside air enters the storage chamber 17, frost is more likely to occur in the storage chamber 17. In the configuration according to the present embodiment, the sealing performance of the storage chamber 17 by the packing 53 can be made higher, and the situation where outside air enters the storage chamber 17 can be suppressed. For this reason, it is more suitable when using the deep freezer 10 as the cooling storage.
