The present invention relates to a cooling storage facility.

A conventional cooling storage facility is described in Patent Document 1. Specifically, the document discloses a cooling storage facility that includes a box body having a storage chamber in which stored items are placed, a machine chamber disposed above the storage chamber, and a door rotatably attached to the box body, the door being provided with a gripping portion (handle) that an operator grasps to open and close the door.

JP 2018-185080 A

However, in the configuration disclosed in Patent Document 1, for example, if an attempt is made to move the cooling storage unit using multiple casters (wheels), there is a possibility that the door attached to the box body may unexpectedly open due to vibration or the like. In addition, it is desirable for the door of the cooling storage unit to ensure the airtightness of the storage chamber so that cold air inside the storage chamber does not flow out of the storage chamber, or air outside the storage chamber does not flow into the storage chamber. Furthermore, it is desirable for the worker to be able to safely grip the handle when opening and closing the door to open and close the door smoothly.

The present invention was completed based on the above circumstances, and one of its objectives is to provide a refrigerated storage cabinet that can prevent the door from opening accidentally. Another objective is to provide a refrigerated storage cabinet that can ensure airtightness of the storage chamber. Yet another objective is to provide a refrigerated storage cabinet whose door can be opened and closed safely and smoothly.

In order to solve the above problems, the cooling storage of the present invention is movable by comprising a storage body having a housing-like shape that opens to the front and a storage chamber capable of storing storage items, a door attached to the storage body so as to be rotatable between a state in which the storage chamber is closed and a state in which the storage chamber is open, and a plurality of wheels arranged on the underside of the storage body, and the door comprises a door body portion that covers the opening edge of the storage chamber when the storage chamber is closed, and a door opening/closing mechanism portion attached to an end of the door body portion opposite to the end of the door on the pivot shaft side, and the door opening/closing mechanism portion comprises a base portion to which a magnet is attached, The device is characterized by having a gripping portion that extends away from the base and can be held by an operator, and a variable abutment portion that can be displaced between a state in contact with the opening edge and a state in which it is separated from the opening edge based on the operation of the gripping portion, and is configured such that, from a state in which the door abuts the opening edge based on the magnetic force of the magnet to close the storage chamber, the variable abutment portion abuts the opening edge when the gripping portion is operated in a direction away from the opening edge, and the door moves away from the opening edge against the magnetic force due to the abutment, changing to an open state of the storage chamber.

In this type of cooling storage, when the door is closed, the magnet of the base arranged on the end of the door body opposite the end on the door pivot shaft side is attracted to the opening edge of the storage chamber, so that the door body can be brought into close contact with the opening edge. This ensures airtightness of the storage chamber and allows the door to be kept closed in an appropriate state even while the cooling storage chamber is moving. In addition, the door opening/closing mechanism is configured to change from a state in which the door abuts the opening edge based on the magnetic force of the magnet to a state in which the door is closed by abutting the opening edge, to a state in which the variable abutment abuts the opening edge, and the door is separated from the opening edge against the magnetic force by the abutment, thereby changing the state to an open state of the storage chamber. Therefore, an operator can smoothly rotate the door to an open state of the storage chamber by operating the handle by gripping the handle and pulling it forward.

In the above configuration, the door body has an elastic part that has elastic force on the surface side of the opening edge part and on the outer end part when the door is in a state where the storage chamber is closed by the door, and a magnet can be attached to the elastic part.

With this type of cooling storage, when the door is closed on the storage chamber, the magnet attached to the elastic part is attracted to the edge of the opening, and the elastic part is elastically deformed by being attracted to the edge of the opening. This improves the airtightness of the storage chamber.

In the above configuration, the door opening/closing mechanism is attached to the edge of the door body, and the grip extends in a direction away from the surface of the door body opposite the surface of the opening edge when the door is in a state where the storage chamber is closed by the door. With such a cooling storage cabinet, a gap is provided between the grip and the opening edge and between the door body and the opening edge, so that an operator can safely insert his or her fingers into the gap and grip the grip to smoothly open and close the door.

In the above configuration, the base can have an abutment surface that can abut against the opening edge, and the magnet attached to the base can be arranged so as to be flush with the abutment surface. With such a cooling storage unit, when the door is closed, the opening edge and the abutment surface abut, and the magnet attached to the base can abut against the opening edge in a face-to-face manner, allowing the door main body to be more closely attached to the opening edge.

In the above configuration, the storage chamber can be configured to accommodate multiple shelves arranged vertically inside, and the cooling storage cabinet can include a machine room disposed below the storage chamber and including a compressor and a condenser, a cooler disposed at an upper portion of the storage chamber, and a refrigerant pipe extending from the machine room into the storage chamber and connecting the compressor, the condenser, and the cooler.

With this type of cooling storage cabinet, cold air can be circulated appropriately within the storage chamber, and the center of gravity of the cooling storage cabinet can be lowered by placing relatively heavy components (compressor and condenser) below the storage chamber. This prevents the cooling storage cabinet from moving or tipping over when an operator opens or closes the door. It is thus possible to provide a cooling storage cabinet that allows an operator to open and close the door safely and smoothly, even if multiple shelves are placed inside the storage chamber.

According to the present invention, it is possible to provide a cooling storage cabinet that can prevent the door from opening accidentally. It is also possible to provide a cooling storage cabinet that can ensure the airtightness of the storage chamber. Furthermore, it is possible to provide a cooling storage cabinet whose door can be opened and closed safely and smoothly.

The cooling storage facility 10 according to an embodiment of the present invention will be described with reference to Figs. 1 to 8. Each figure will be described with the arrow direction F indicating the forward direction (the direction toward the front side of the cooling storage facility 10), the arrow direction B indicating the rearward direction (the direction toward the rear side of the cooling storage facility 10), the arrow direction U indicating the upward direction, the arrow direction D indicating the downward direction, the arrow direction L indicating the leftward direction, and the arrow direction R indicating the rightward direction.

As shown in FIG. 1, the cooling storage facility 10 comprises a cart 12 having a number of casters (wheels) 11, a vertically long storage facility body 13 standing on the cart 12, and a door 70. The casters 11 can be rotated to allow easy movement on the floor. As shown in FIG. 2 to FIG. 4, the storage facility body 13 is in the form of a housing with an opening at the front, and has a storage chamber 15 capable of storing items, and a machine room 16 disposed below the storage chamber 15. The storage chamber 15 is insulated by filling the walls and the inside of the door 70 that form the storage chamber 15 in the storage facility body 13 with insulating material, but the insulating material is not shown in each cross-sectional view.

Inside the storage chamber 15, two shelf posts 20 are fixed to each of the left and right side walls 15A, 15B, one at the front and one at the back. A tray guide 21 is detachably attached to each of the left and right side walls 15A, 15B so as to span the front and rear shelf posts 20, and a tray (shelf) 22 carrying stored items such as foodstuffs can be inserted from the front and placed on the pair of tray guides 21 on the left and right. Note that multiple pairs of tray guides 21 can be attached inside the storage chamber 15, making it possible to place multiple trays 22 lined up vertically.

The cooling storage 10 is equipped with a cooling device 30 for cooling the inside of the storage body 13 (storage chamber 15). As shown in Figures 4 and 5, a part of the cooling device 30 (machine room side unit) 30A is provided in the machine room 16. The machine room side unit 30A is equipped with a condenser 31, a condenser fan 32, and a compressor 33. The machine room side unit 30A is arranged on the right side of the machine room 16, and the condenser 31, condenser fan 32, and compressor 33 are arranged in this order from the front. Refrigerant pipes 34A and 34B extend from the machine room side unit 30A toward the rear, and are circulated and connected to a cooler (evaporator) 35 arranged in the storage chamber 15 by these refrigerant pipes 34A and 34B. The refrigerant pipe 34A is a discharge side refrigerant pipe through which the compressor 33 discharges the refrigerant to the cooler 35 side via the condenser 31, and the refrigerant pipe 34B is a suction side refrigerant pipe through which the compressor 33 draws the refrigerant from the cooler 35 side. When the cooling device 30 is operated, the cooler 35 generates cold air, which can cool the storage chamber 15.

A slider 36 that can slide in the front-rear direction is provided on the top surface of the cart section 12 in the machine room 16, and the condenser 31, condenser fan 32, and compressor 33 are fixed on the slider 36. A removable front panel 16A is attached to the front of the machine room 16, as shown in Figures 1 to 5. By removing the front panel 16A and moving the slider 36 forward, it is possible to perform maintenance on the machine room unit 30A.

As shown in FIG. 5, an electrical equipment box 40 for controlling the operation of each device equipped in the cooling storage cabinet 10 is provided in the machine room 16, to the left of the machine room unit 30A (to the left of the machine room 16) and behind the front panel 16A. A partition member 41 for partitioning a generally rectangular parallelepiped space is provided behind the electrical equipment box 40, and a drain tank 42 for collecting drainage water from the cooling storage cabinet 10 is provided in the space partitioned by the partition member 41. The space partitioned by the partition member 41 opens to the rear, and the drain tank 42 can be easily removed from the rear side.

As shown in FIG. 4, the cooler 35 is fixed to the ceiling surface 15C of the storage chamber 15 in the storage body 13. The above-mentioned refrigerant pipes 34A, 34B are bent at the rear end in the machine chamber 16, extend upward, and are connected to the cooler 35. Specifically, the refrigerant pipes 34A, 34B enter the storage chamber 15 from the machine chamber 16 and extend along the right side end of the back surface 15D of the storage chamber 15. The refrigerant pipes 34A, 34B are covered by a refrigerant pipe cover 50 attached along the right rear corner of the storage chamber 15.

The above-mentioned cooler 35 and the connection portion of the refrigerant pipes 34A and 34B to the cooler 35 are covered by a housing member 51. The housing member 51 is composed of a metal spacer 51A attached to the ceiling surface 15C and a resin air duct 51B attached to the lower side of the spacer 51A. A cooler chamber 52 is provided between the housing member 51 and the ceiling surface 15C of the storage chamber 15. In the air duct 51B, an internal fan 53 is provided in front of the cooler 35. By driving the internal fan 53, air in the storage chamber 15 is sucked into the cooler chamber 52. A gap 54 is provided between the rear end of the air duct 51B and the back surface 15D of the storage chamber 15. The cold air that is sucked from the internal fan 53 and generated by heat exchange while passing through the cooler 35 is blown out downward from the gap 54. It can also be said that the gap 54 is an outlet of the cooler chamber 52. With the above configuration, when the compressor 33, the condenser fan 32, and the interior fan 53 are driven, cold air is circulated and supplied from the cooler chamber 52 to the storage chamber 15.

The air duct 51B also functions as a drain pan. The bottom surface of the air duct 51B is inclined downward toward the rear, so that water dripping from the cooler 35 onto the bottom surface of the air duct 51B flows toward the rear. A drain hose 60 is connected to the rear end of the air duct 51B. The drain hose 60 extends through the inside of the wall on the rear side 15D of the storage body 13 to the machine room 16. As shown in FIG. 5, the lower end of the drain hose 60 opens above the drain tank 42, and the defrosted water generated in the cooler room 52 flows down and accumulates in the drain tank 42. In this embodiment, the frost formed on the cooler 35 due to the cooling operation is melted by stopping the cooling operation as appropriate. The defrosting method is not limited to such off-cycle defrosting, and a defrosting heater may be attached to the cooler 35 and melted by applying electricity to the heater. In addition, when moving the cooling storage unit 10 with the power cord unplugged and the power supply stopped, the frost may melt as the cooling operation stops, resulting in the generation of defrosted water.

2 to 4, the storage chamber 15 has an opening 17 at the front end, which is an opening portion that opens forward. The opening 17 has an opening edge portion 17A at its front edge portion, which has a frame-like shape when viewed from the front. A metal plate 18 made of metal is attached to the left side of the opening edge portion 17A and to the center portion in the vertical direction in a manner that follows the opening edge portion 17A. The door 70 is attached to the storage chamber 15 so as to be rotatable about a rotation axis O as a rotation axis by two hinge portions 14A, 14B provided on the right side, upper and lower sides of the opening edge portion 17A. FIGS. 1 and 4 show a state in which the door 70 closes the storage chamber 15, and FIGS. 2 and 3 show a state in which the door 70 opens the storage chamber 15. The metal plate 18 may be attached so that its front surface is flush with the opening edge portion 17A. The storage chamber 15 may also have a metallic opening edge 17A at its opening 17, without the metal plate 18.

The door 70 includes a door body 71 having a long plate shape in the vertical direction, and a door opening/closing mechanism 80 attached to the edge 71B1 of the end 71B of the door body 71 opposite the end 71A on the rotation axis O side. The door body 71 is shaped to cover a part (inner part) of the opening edge 17A of the storage chamber 15 when the door 70 closes the storage chamber 15. When the door 70 closes the storage chamber 15, a packing 72 (described in detail later) provided on the peripheral part (outer end) of the door body 71 of the door 70 is in close contact with the opening edge 17A, and the opening of the opening 17 is blocked by the door body 71, sealing the inside of the storage chamber 15. When the door 70 opens the storage chamber 15, the door 70 rotates forward about the rotation axis O as a rotation axis, opening the inside of the storage chamber 15.

Figure 6 shows door 70 as seen from the side of surface (back surface) 70B that comes into close contact with opening edge 17A. Door body 71 is provided with elastic gasket (elastic portion) 72 that is provided in a frame shape on the back surface 70B side and on the peripheral end (outer end). Gasket 72 is hollow and gradually becomes higher toward the back surface as it moves outward. Four band-shaped magnets M1 are attached inside gasket 72. Magnets M1 can be attracted to opening edge 17A of storage chamber 15 by magnetic force.

1 and 2 and 6 to 8, the door opening/closing mechanism 80 includes a base 81 to which a magnet M2 is attached that can be attracted to the metal plate 18 of the opening edge 17A, a gripping portion 82 that is attached to the base 81 by an attachment portion 84 and can be gripped by an operator, and a variable abutment portion 83, which will be described later. The base 81 includes a flat abutment surface 81A that abuts against the metal plate 18 provided on the opening edge 17A when the door 70 closes the storage chamber 15. The magnet M2 attached to the base 81 has a long plate shape in the vertical direction and is arranged so as to be flush with the abutment surface 81A. Therefore, when the door 70 closes the storage chamber 15, the magnet M2 attached to the base 81 abuts against the metal plate 18 in a face-to-face manner. For example, the "R25 Series" from "Component Hardware Group" can be used as the door opening/closing mechanism 80.

7 and 8, the gripping portion 82 extends upward (away from the base 81) from the base 81 and forward (away from the front surface 70A of the door 70) from the front surface 70A, which is the surface opposite the back surface 70B of the door 70, toward the upper end 82A. The gripping portion 82 is operable by an operator to swing its upper end 82A and lower end 82B in the front-rear direction with the attachment portion 84 as a fulcrum. For example, when the upper end 82A of the gripping portion 82 is tilted forward by the operator from the state shown in FIG. 7 (this state is considered to be the steady state) (when the gripping portion 82 is operated in the direction away from the opening edge portion 17A with the door 70 closing the storage chamber 15), the lower end 82B tilts backward, and the gripping portion 82 assumes the state shown in FIG. 8 (this state is considered to be the forward tilted state). In addition, a biasing member 85 made of a spring or the like is attached to the rear end of the lower end 82B of the gripping portion 82 to bias the lower end 82B forward.

The variable contact portion 83 is cylindrical with its height in the front-rear direction, and is configured to be displaceable between a state in which it contacts the metal plate 18 of the opening edge portion 17A and a state in which it is separated from the metal plate 18 based on the operation of the grip portion 82. Specifically, as shown in FIG. 7, when the grip portion 82 is in a stationary state, the variable contact portion 83 is housed in the base portion 81, and the rear end portion of the variable contact portion 83 is located forward of the contact surface 81A of the base portion 81 and separated from the metal plate 18 (note that when the grip portion 82 is in a stationary state, the variable contact portion 83 may be disposed in a position flush with the contact surface 81A, and in this case, for example, the metal plate 18 may be pressed with a force smaller than the magnetic force of the magnet M2 provided on the base portion 81). On the other hand, as shown in FIG. 8, when the grip 82 is in a forward tilted state, the rear end of the variable abutment portion 83 extends rearward from the abutment surface 81A of the base 81 (displaced to a state in which it abuts against the opening edge portion 17A). When the door 70 is in a state in which the storage chamber 15 is closed, the grip 82 is in a forward tilted state, and the rear end of the variable abutment portion 83 abuts against the metal plate 18 of the opening edge portion 17A and presses against the metal plate 18 against the magnetic force of the magnet M2 provided on the base 81.

1 and 7, when the door 70 closes the storage chamber 15 and the gripping portion 82 is in a stationary state, the magnet M2 (see FIG. 6) provided on the base 81 is attracted to the metal plate 18 of the opening edge 17A, and the door 70 abuts against the opening edge 17A based on the magnetic force of the magnet M2. The gasket 72 of the door 70 is also in close contact with the opening edge 17A based on the magnetic force of the magnet M1 provided inside it. From this state, when the operator grasps the upper end 82A of the gripping portion 82 and tilts it forward, the gripping portion 82 is tilted forward, and as shown in FIG. 8, the rear end of the variable abutment portion 83 is displaced toward the opening edge 17A (rearward) and abuts against the metal plate 18 of the opening edge 17A, and separates the magnet M2 from the metal plate 18 against the magnetic force of the magnet M2 provided on the base 81. Then, as the door 70 moves away from the opening edge 17A, the door 70 changes to a state in which the storage chamber 15 is open, as shown in FIG. 2, and the biasing member 85 biases the lower end 82B of the gripping portion 82 forward, causing the gripping portion 82 to return to its normal state.

Next, the effects of this embodiment will be described. The cooling storage 10 in this embodiment is a housing-like structure that opens to the front and includes a storage body 13 having a storage chamber 15 capable of storing storage items, a door 70 that is attached to the storage body 13 so as to be rotatable between a state in which the storage chamber 15 is closed and a state in which the storage chamber 15 is open, and a plurality of casters 11 that are arranged on the underside of the storage body 13, so that the cooling storage 10 is movable. The door 70 includes a door body portion 71 that covers the opening edge portion 17A of the storage chamber 15 when the storage chamber 15 is closed, and a door opening/closing mechanism portion 80 that is attached to the end portion 71B of the door body portion 71 opposite to the end portion 71A on the side of the rotation axis O of the door 70. The door opening/closing mechanism portion 80 is configured to have a magnet M2. The device is equipped with an attached base 81, a gripping portion 82 that extends away from the base 81 and can be gripped by an operator, and a variable abutment portion 83 that can be displaced between a state in contact with the opening edge portion 17A and a state in which it is separated from the opening edge portion 17A based on the operation of the gripping portion 82. When the gripping portion 82 is operated in a direction away from the opening edge portion 17A, the variable abutment portion 83 abuts against the opening edge portion 17A, and the door 70 moves away from the opening edge portion 17A against the magnetic force of the magnet M2, changing to a state in which the storage chamber 15 is open.

With this cooling storage cabinet 10, when the door 70 closes the storage chamber 15, the magnet M2 of the base 81 arranged on the end 71B of the door main body 71 opposite the end 71A on the rotation axis O side of the door 70 attracts the opening edge 17A of the storage chamber 15, thereby making the door main body 71 tightly attached to the opening edge 17A. This ensures the airtightness of the storage chamber 15 and allows the door 70 to maintain the storage chamber 15 in an optimal closed state even when the cooling storage cabinet 10 is moving. In addition, the door opening/closing mechanism 80 is configured so that when the door 70 abuts against the opening edge 17A based on the magnetic force of the magnet M to close the storage chamber 15, the gripping portion 82 is operated in a direction away from the opening edge 17A, causing the variable abutment portion 83 to abut against the opening edge 17A, and the door moves away from the opening edge 17A against the magnetic force, changing the state to an open state for the storage chamber 15. Therefore, an operator can smoothly rotate the door 70 to an open state for the storage chamber 15 by operating the gripping portion 82 by grasping the upper end portion 82A of the gripping portion 82 and pulling it forward.

When the door 70 is in a state where the storage chamber 15 is closed, the door body 71 is provided with a gasket 72 having elasticity on the surface 70B side of the opening edge portion 17A and on the outer end, and a magnet M1 is attached to the gasket 72.

With this type of cooling storage 10, when the door 70 closes the storage chamber 15, the magnet M1 attached to the packing 72 is attracted to the opening edge 17A, and the packing 72 is drawn to the opening edge 17A, allowing it to elastically deform. This improves the airtightness of the storage chamber 15.

The door opening/closing mechanism 80 is attached to the edge 71B1 of the door body 71, and the upper end 82A of the grip 82 extends in a direction away from the surface 70A opposite the surface 70B of the door body 71 on the opening edge 17A side when the door 70 is in a state where the storage chamber 15 is closed by the door 70. With this type of cooling storage cabinet 10, a gap is provided between the upper end 82A of the grip 82 and the opening edge 17A and between the door body 71 and the door body 71, so that an operator can safely insert his or her fingers into the gap and grip the grip 82 to smoothly open and close the door 70.

The base 81 also has an abutment surface 81A that can abut against the metal plate 18 of the opening edge 17A, and the magnet M2 attached to the base 81 is arranged so as to be flush with the abutment surface 81A. With this type of cooling storage cabinet 10, when the door 70 is closed, the abutment surface 81A abuts against the metal plate 18 of the opening edge 17A, and the magnet M2 attached to the base 81 can abut against the metal plate 18 of the opening edge 17A in a face-to-face manner, allowing the door main body 71 to be even more closely attached to the opening edge 17A.

The storage chamber 15 is configured so that multiple trays 22 can be placed inside it in a vertically aligned manner, and the cooling storage facility 10 includes a machine room 16 disposed below the storage chamber 15 and including a compressor 33 and a condenser 31, a cooler 35 disposed at the top of the storage chamber 15, and refrigerant pipes 34A and 34B that run from the machine room 16 into the storage chamber 15 and connect the compressor 33, the condenser 31, and the cooler 35.

With this type of cooling storage cabinet 10, cold air can be circulated appropriately within the storage chamber 15, and the center of gravity of the cooling storage cabinet 10 can be lowered by arranging the relatively heavy components (compressor 33 and condenser 31) below the storage chamber 15. This prevents the cooling storage cabinet 10 from moving or tipping over when an operator opens or closes the door 70. It is thus possible to provide a cooling storage cabinet 10 that allows an operator to safely and smoothly open and close the door 70 even when multiple trays 22 are placed in the storage chamber 15.
