Japanese Unexamined Patent Publication No. 2014-215019

By the way, in the above storage, since the storage chamber may be contaminated by the objects placed on the tray (for example, broth of food), it is required to clean the storage chamber. In order to clean the containment chamber, for example, it is conceivable to provide an injection portion capable of injecting water (washing water) in the containment chamber. However, when water is sprayed in the containment chamber, there is a concern that the water in the containment chamber may leak to the outside of the refrigerator. As a result, there is a concern that the water leaked to the outside of the refrigerator may fall to the floor surface.

The present invention has been completed based on the above circumstances, and an object of the present invention is to suppress a situation in which water leaking out of the refrigerator falls to the floor surface.

In order to solve the above problems, the storage of the present invention includes a box-shaped storage main body having a storage chamber opened in front, a carriage portion that can move on the floor on which the storage main body is installed, and the storage. A cart including a cart main body that can be inserted or removed from the front of the chamber, a connecting portion that connects the cart main body and the trolley, and a door that can open and close the storage chamber. A door including a first door constituting the upper part of the door and a second door forming the lower part of the door, and an injection unit provided in the accommodation chamber capable of injecting water. The second door is provided with a drain pan provided on the second door, the connection portion is arranged between the storage body and the second door, and the second door is attached to the connection portion when the door is closed. The storage main body is provided with a bottom wall portion forming the bottom surface of the storage chamber, and the cart main body portion is housed in the storage chamber. In the unaccommodated state of the cart, the packing is interposed between the second door and the front surface of the bottom wall portion, and the drain pan is arranged below the packing.

According to the above configuration, the gap between the second door and the front surface of the bottom wall portion can be filled with packing when the cart is not accommodated. Assuming that when the water from the injection portion drips below the packing, the dripping water can be received by the drain pan, so that the situation where the water leaked to the outside of the refrigerator falls to the floor surface can be suppressed. Further, in the above configuration, when the door is closed, the second door is displaced forward relative to the first door, so that the situation where the connecting portion of the cart and the second door interfere with each other can be suppressed. If the drain pan provided on the bottom wall of the storage body is configured to receive water dripping downward from the front end of the bottom wall, the drain pan will protrude from the front of the bottom wall. There is concern that it may interfere with the drain pan. In the above configuration, since the drain pan is provided on the second door, the drain pan can be displaced forward relative to the first door together with the second door, and the situation where the drain pan and the connecting portion of the cart interfere with each other can be suppressed.

Further, a main body side drain pan provided in the storage main body is provided, the drain pan has a long longitudinal shape in the left-right direction of the storage, and water in the drain pan is applied to one end portion of the drain pan in the longitudinal direction. A discharge hole for discharging is provided below the main body side drain pan, and the main body side drain pan is arranged at a position that does not overlap with the cart in a front view, and the discharge hole is arranged above the main body side drain pan in the cart unaccommodated state. Can be done.

The water received by the drain pan goes to the drain pan on the main body side through the drain hole. Therefore, the situation where water overflows from the drain pan can be suppressed. As a result, the amount of water that can be received can be increased as compared with the configuration provided only with the drain pan. Further, since the drain pan on the main body side is arranged at a place where it does not overlap with the cart in the front view, it is possible to suppress a situation in which the cart is prevented from being taken in and out. The front view is a state in which the storage is viewed from the front, and the left-right direction is the left-right direction when the storage is viewed from the front.

Further, the door is rotatably attached to the storage body at one side end in the left-right direction of the storage via a hinge, and the drain pan is the other end in the longitudinal direction of the drain pan. The drain pan side wall portion, which is a side wall portion constituting the above, is provided, and the other end portion may be an end portion on the opposite side to the hinge.

By providing the drain pan side wall portion that constitutes the end on the opposite side of the hinge, it is possible to suppress the situation where water is discharged from the end on the opposite side of the hinge in the drain pan due to the centrifugal force when opening and closing the door. it can.

Further, a through hole is formed in the bottom wall portion of the drain pan, and the through hole can be arranged above the drain pan on the main body side in the cart unaccommodated state.

The water received by the drain pan goes to the drain pan on the main body side through the through hole. Therefore, the situation where water overflows from the drain pan can be suppressed.

Further, the drain pan may be made of metal, and the surface of the drain pan on the side of the storage chamber may be provided with a protrusion made of synthetic resin that protrudes toward the connection portion. By interposing the protruding portion between the connecting portion and the drain pan, it is possible to suppress a situation in which the metal drain pan comes into direct contact with the connecting portion of the cart and a metallic sound is generated.

Further, a tank provided on the lower surface of the bottom wall portion and connected to a drain port formed through the bottom wall portion, a pump for supplying water in the tank to the injection portion, and a front surface of the tank. It may be provided with a tank cover that covers the provided electrical components. The water from the injection part is stored in the tank through the drain port, and the water stored in the tank is supplied to the injection part by the pump. As a result, water can be circulated between the injection unit and the tank, and the accommodation chamber can be cleaned while reducing the supply of water from the outside (water supply or the like). Further, by providing the tank cover, it is possible to more reliably suppress the situation where water is splashed on the electric parts provided on the front surface of the tank.

Further, the tank is provided with a tank provided on the lower surface of the bottom wall portion and connected to a drain port formed through the bottom wall portion, and a pump for supplying water in the tank to the injection portion. A suction port connected to the pump is provided on the side wall portion of the tank, which is a side wall portion of the tank, and a plate-shaped member is provided on the bottom wall of the tank at a position above the suction port in the tank. It is assumed that the tank bottom wall portion, which is a portion, is arranged to face the tank bottom wall portion at a distance, and the tank side wall portion, the tank bottom wall portion, and the plate-shaped member form a communication space that communicates with the suction port. be able to.

When the pump operates, the water in the tank is sucked into the pump through the suction port. Along with this, a vortex may be generated due to the flow of water in the tank. When such a vortex reaches the suction port, air is sucked into the suction port together with water. In the above configuration, a plate-shaped member constitutes a communication space that communicates with the suction port. As a result, the water in the tank goes to the suction port via the communication space. If the water is directed to the suction port via the communication space, the water path from the water surface to the suction port can be lengthened by the amount of the communication space. Generally, since the vortex is generated in a form extending from the water surface along the flow of water, it is possible to suppress the situation where the generated vortex reaches the suction port by lengthening the water path from the water surface to the suction port. As a result, even when the water level in the tank is low, it is possible to suppress a situation in which air is sucked into the suction port together with the water in the tank and heads toward the pump (so-called air shaving), and the water in the tank can be further reduced. It can be reliably supplied to the injection unit.

According to the present invention, it is possible to suppress a situation in which water leaking to the outside of the refrigerator falls to the floor surface.

(For example, four, only two are shown in FIG. 12) are provided so as to be arranged along the line.

As shown in FIG. 13, the nozzle 46F is provided in the lowermost extending portion 46E of the four extending portions extending in the front-rear direction of the pipe 46A. The nozzle 46D can inject water toward the cooler 35, and the nozzle 46F can inject water toward the tray body 42B of the detergent tray 42, which will be described later. Further, as shown in FIGS. 12 and 13, a plurality of injection holes 46G capable of injecting water toward the internal fan 36 are formed on the surface on the right side of the pipe 46A.

As shown in FIG. 14, the detergent tray 42 includes a frame member 42A attached to the surface 37B1 (the surface facing the right side) of the cover 37B, and a tray body 42B arranged inside the frame member 42A. The tray body 42B has a box shape that is opened upward, and an operator can put detergent inside the tray body 42B. The tray body 42B is rotatably attached to the frame member 42A via the shaft portion 42C. The tray body 42B has a facing wall portion 42D facing the surface 37B1 of the cover 37B, and the facing wall portion 42D is configured to cover the through hole 37C formed in the cover 37B. The nozzle 46F described above is arranged to face the through hole 37C.

As a result, as shown in FIG. 15, the water (arrow line L1) ejected from the nozzle 46F hits the facing wall portion 42D through the through hole 37C, so that the tray body 42B rotates around the shaft portion 42C and the tray. The detergent contained in the main body 42B is configured to fall on the bottom wall portion 15F. The detergent that has fallen on the bottom wall portion 15F mixes with the water on the bottom wall portion 15F (water injected from the injection unit 45 or the cooling unit side injection unit 46) and collects in the tank 41 through the drain port 15G. As a result, by operating the pump 43, the water mixed with the detergent can be circulated between the tank 41 and the injection unit 45 (or the cooling unit side injection unit 46).

Further, as shown in FIGS. 8 and 9, the accommodation space 18 is provided with an intake fan 50 and an intake valve 51. The fan 50 is connected to the tank 41 by a pipe 54. When the fan 50 is operated with the valve 51 open, the air in the accommodation space 18 is sent to the accommodation chamber 15 via the tank 41 and the drain port 15G. As shown in FIG. 2, the accommodation space 18 is a space surrounded by a front wall portion 18A arranged on the left side of the door 17A and a side wall portion 18B extending rearward from the left end portion of the front wall portion 18A. , Opened upwards and backwards.

Further, as shown in FIG. 7, the cooling cabinet main body 11 is provided with an exhaust pipe 55 for discharging the air in the storage chamber 15 to the outside of the refrigerator (outside the cooling cabinet main body 11). The exhaust pipe 55 extends upward from the inside of the case 37 and is provided so as to penetrate the ceiling wall portion 15E. As a result, the upper end of the exhaust pipe 55 is arranged above the ceiling wall portion 15E. A valve 55A is provided in the exhaust pipe 55, and by opening and closing the valve 55A, the exhaust passage by the exhaust pipe 55 can be opened and closed. Further, the exhaust pipe 55 is arranged on the downstream side (left side) of the internal fan 36.

In the drying operation, the fan 50, the internal fan 36, and the heater 39 are operated with the valve 51 and the valve 55A open. As a result, when the fan 50 operates, the outside air is sent to the accommodation chamber 15 via the tank 41 and the drain port 15G. Further, the air sucked into the case 37 by the operation of the internal fan 36 becomes warm air by being heated by the heater 39, and is blown into the accommodation chamber 15 to be blown into the accommodation chamber 15. As the temperature rises, the water content in the containment chamber 15 gradually changes to water vapor. Further, the water vapor and air in the accommodation chamber 15 are exhausted from the exhaust pipe 55. As a result, the inside of the storage chamber 15 can be dried. Further, in the drying operation, since the outside air is sent to the storage chamber 15 via the tank 41 and the drain port 15G, the inside of the tank 41 can be dried. The washing operation and the drying operation are executed in a state where the cart main body 20 is not housed in the storage chamber 15 (the cart is not housed).

It has become. The extension portions 30D and 30E may not be provided.

The packings 31, 32, and 32 form the opening edge of the opening 33. In the cart housing state, as shown in FIGS. 4 and 19, the front surfaces of the packings 31, 32, and 32 abut on the plate portion 23 of the cart 13. That is, the packings 31, 32, and 32 are cart receiving portions that regulate the rearward displacement of the cart 13 by receiving the plate portion 23 of the cart 13 from the rear, and the opening component 28 constitutes the cart receiving portion. It is a receiving part constituent member. In the cart accommodating state, the opening 33 is closed from the front by the plate portion 23.

As shown in FIG. 16, the plate 34 extends in the left-right direction, and the upper surface 34A of the plate 34 constitutes the bottom surface (inner surface of the opening) of the opening 33. Further, in the cart uninserted state (in other words, the cart unaccommodated state) in which the base 24 of the cart 13 is not inserted into the opening 33, it is provided on the surface of the door 12 on the accommodation chamber 15 side as shown in FIG. A sheet member 70 (described later) is arranged in the opening 33. The upper surface 34A (bottom surface arranged below the closing member) is arranged below the seat member 70, and is an inclined surface that inclines downward toward the rear. Further, on the upper surface 34A, a plurality of groove portions 34B extending in the front-rear direction are formed so as to be lined up in the left-right direction. As shown in FIGS. 20 and 21, the groove portion 34B is formed in a rear portion of the upper surface 34A and is opened upward and rearward. Further, the bottom surface 34C of the groove portion 34B is an inclined surface that inclines downward toward the rear.

Next, the configuration of the door 12 of the present embodiment will be described. As shown in FIG. 1, the door 12 of the present embodiment includes a first door 61 that constitutes the upper part of the door 12, a second door 62 that constitutes the lower part of the door 12, and a first door 61 and a second door 62. A hinge member 63 and a hinge member 63 for connecting the doors and the doors are provided. As shown in FIG. 20, the second door 62 is arranged to face the opening component 28. The hinge member 63 includes a hinge shaft 63A extending in the left-right direction. As a result, the second door 62 is rotatably attached to the first door 61 via the hinge member 63. Specifically, the second door 62 is rotatable with respect to the first door 61 so that the lower end portion of the second door 62 faces forward. That is, the second door 62 is configured to be able to be displaced forward relative to the first door 61.

The first door 61 is configured to cover most of the opening of the cart arrangement space 15A (mainly a portion where the opening component 28 is not arranged) from the front. Further, as shown in FIG. 18, door packings 12D having a rectangular frame shape are provided on four sides of the peripheral edge portion on the back surface of the first door 61. The door packing 12D has a function of closing the gap between the first door 61 and the cooler main body 11. Further, as shown in FIG. 20, a seat member 12B and a seat member 12E are provided on the back surface of the first door 61. The seat members 12B and 12E are arranged so as to hang down from the back surface of the first door 61. The seat members 12B and 12E are arranged so as to cover both the lower end portion of the first door 61 and the second door 62 from the rear side. That is, the seat members 12B and 12E are arranged between the second door 62 and the opening component 28. The seat member 12E is interposed between the door 12 and the seat member 12B.

Further, as shown in FIG. 20, the seat members 12B and 12E are formed by a horizontal packing 12H (a part of the door packing 12D) provided on the back surface of the first door 61 and a packing 32 provided on the columnar member 30. It is intervened between them. In the cart housing state shown in FIG. 19, the lateral packing 12H is pressed from the front to the upper end portion of the plate portion 23 via the seat members 12E, 12B, 70. A magnet 12J is housed inside the horizontal packing 12H, and by attracting the horizontal packing 12H to the metal plate portion 23 by the magnet 12J, the horizontal packing 12H, the sheet members 12E, 12B, 70, The plate portion 23 can be brought into close contact with the plate portion 23. The gap between the door 12 (more specifically, the first door 61) and the plate portion 23 is closed by the horizontal packing 12H and the seat members 12E, 12B, 70.

As shown in FIG. 20, the second door 62 includes a second door main body 66 attached to the hinge member 63, and a holding plate 65 that covers the second door main body 66 from behind. The hinge shaft 63A, which is the rotation shaft of the second door 62, extends along the left-right direction. A hinge spring 64 is wound around the hinge shaft 63A. In the unaccommodated state in which the cart main body 20 is not arranged in the accommodating chamber 15, the seat member 12B is configured to close the opening 33 of the opening constituent member 28 from the front. In the uncarried state of the cart, the second door 62 is in a posture of slightly rotating forward as compared with the natural state (the state in which the door 12 is opened), and the hinge spring 64 (the urging member) causes the second door 62 to rotate forward. The two doors 62 are urged toward the opening component 28 side.

In the cart unaccommodated state, both the seat member 12B and the seat member 12E are pressed against the packing 31 of the opening component 28 by the pressing plate portion 65. Therefore, in the unaccommodated state of the cart, it is possible to suppress a situation where a gap is generated between the seat member 12B and the opening constituent member 28, and the opening 33 can be more reliably closed by the seat member 12B, so that the opening 33 can be closed. It is possible to suppress a situation in which the air in the accommodation chamber 15 leaks to the outside of the refrigerator.

As shown in FIG. 19, in the cart accommodating state, a pair of pillars 22 and 22 which are connecting portions 21 are arranged between the second door 62 and the cooler main body 11. Therefore, the second door is configured to be rotationally displaced forward (relatively displaced forward) with respect to the first door 61 by abutting against the pair of pillars 22 and 22 when the door 12 is closed. There is. In other words, in the cart-accommodated state, the second door 62 is rotated forward by the amount of the pillar 22 from the cart-unaccommodated state. In this way, since the second door 62 can be displaced forward relative to the first door 61, it is possible to avoid a situation in which the pillar 22 and the second door 62 interfere with each other when the door 12 is closed. it can.

Further, the seat member 12E is made of a material having a lower adhesion to the pressing plate portion 65 than the seat member 12B. In the cart accommodating state, the flexible seat member 12E and the seat member 12B are in a bent state following the shape of the pillar 22. When the door 12 is opened from this state, the seat members 12E and 12B are in a hanging state, and the opening 33 can be covered by the seat members 12E and 12B by closing the door 12 after the cart is not accommodated.

If the cart is not accommodated while the seat members 12E and 12B are held in a bent state, it becomes difficult for the seat members 12E and 12B to reliably close the opening 33. By interposing the seat member 12E having a relatively low adhesion between the seat members 12B, when the door 12 is opened in the cart housed state, the seat member 12E is in close contact with the holding plate portion 65 and is bent. Since the situation of being held can be suppressed, the seat members 12E and 12B can be in a hanging state, and the opening 33 can be reliably covered in the cart unaccommodated state.

The sheet member 12B arranged on the storage chamber 15 side is preferably made of a material having excellent cold resistance and chemical resistance because water containing detergent and cold air in the storage chamber 15 may come into direct contact with the sheet member 12B. In the present embodiment, by interposing the seat member 12E between the seat member 12B and the second door 62, it is possible to suppress the situation where the seat member 12B comes into contact with the holding plate portion 65. Therefore, when examining the material of the sheet member 12B, it is not necessary to consider the adhesion to the holding plate portion 65, so that the material of the sheet member 12B is made a more optimum material from the viewpoint of cold resistance and chemical resistance. be able to. The sheet member 12B can be, for example, a silicon sheet having excellent cold resistance and chemical resistance. However, since the silicon sheet generally has high adhesion, in a configuration not provided with the sheet member 12E, there is a possibility that the silicon sheet adheres to the pressing plate portion 65 in the cart housing state and the bent state is maintained. When the sheet member 12B is a silicon sheet, for example, the sheet member 12E may be a rubber sheet having a lower adhesion than the silicon sheet, but the materials of the sheet member 12E and the sheet member 12B are limited to this. However, it can be changed as appropriate.

As shown in FIG. 20, a drain pan 67 is provided at the lower end of the back surface (the surface on the accommodation chamber 15 side) of the second door main body 66. The drain pan 67 has a box shape that is opened upward, and has a long longitudinal shape that is long in the left-right direction. In the cart unaccommodated state of FIG. 20, the packing 31 is interposed between the second door 62 and the front surface 29A of the extension portion 29, and the drain pan 67 is arranged below the packing 31 (and the seat members 12B and 12E). Will be done.

Further, as shown in FIG. 17, the cooling cabinet main body 11 is provided with a main body side drain pan 68. The main body side drain pan 68 is arranged below the cooler main body 11, and as shown in FIG. 23, has a box shape (shallow dish shape) opened upward, and the front end portion 68D of the main body side drain pan 68 is cooled. It is arranged so as to project forward from the front surface 15F1 of the refrigerator body 11. The main body side drain pan 68 is arranged on the right side of the opening 33 in the left-right direction as shown in FIG. That is, the drain pan 68 on the main body side is arranged at a position that does not overlap with the cart 13 in the front view.

As shown in FIG. 18, at one end in the longitudinal direction of the drain pan 67 (the right end of the rapid cooling cabinet, the left end in FIG. 18), the water in the drain pan 67 is discharged below the drain pan 67. Hole 67A is provided. The discharge hole 67A is provided at the right end of the drain pan 67 (on the right side of the rapid cooling cabinet) and is opened on the right side (corresponding to the left side in FIG. 18). More specifically, as shown in FIG. 24, the discharge hole 67A is a gap between the front wall portion 67F of the drain pan 67 and the rear wall portion 67G of the drain pan 67. In the uncarried state of the cart, the discharge hole 67A is arranged above the drain pan 68 on the main body side as shown in the plan view of FIG. 24, and is arranged so as to overlap the drain pan 68 on the main body side in the plan view. The lower side of FIG. 24 is the front side of the rapid cooling cabinet 10. Further, a plurality of through holes 67D1 (six in FIG. 24) penetrating in the vertical direction are provided at the end of the bottom wall portion 67D of the drain pan 67 on the discharge hole 67A side. The plurality of through holes 67D1 have a circular shape, for example, and are arranged above the drain pan 68 on the main body side in a cart unaccommodated state. Therefore, the water on the drain pan 67 falls onto the drain pan 68 on the main body side through the discharge hole 67A or the through hole 67D1. In FIG. 24, the flow of water falling from the discharge hole 67A onto the drain pan 68 on the main body side is indicated by the arrow line L4. According to the present embodiment, the water received in the drain pan 67 goes to the drain pan 68 on the main body side through the through hole 67D1 in addition to the discharge hole 67A. Therefore, the situation where water overflows from the drain pan 67 can be more reliably suppressed.

The main body side drain pan 68 is provided with a through hole 68A for draining the water in the main body side drain pan 68. As shown in FIG. 25, a drainage pipe 68B is connected to the through hole 68A. The pipe 68B extends along the lower surface of the cooling cabinet main body 11, and extends to, for example, a drainage groove (not shown) provided outside the refrigerator.

Further, the drain pan 67 is made of a metal plate material, and as shown in FIGS. 19 and 22, the drain pan 67 projects toward the connecting portion 21 side (accommodation chamber 15 side) on the surface 67B of the drain pan 67 on the accommodation chamber 15 side. A protrusion 69 made of synthetic resin is provided. The protrusion 69 is attached to a portion closer to the end on the right side (hinge 12A side) on the surface 67B on the accommodation chamber 15 side. The protruding portion 69 has, for example, a block shape and is made of a highly slidable synthetic resin (for example, polyacetal or the like), but the shape and material are not limited thereto. In the cart housing state, the drain pan 67 has an inclined posture that follows the posture of the second door 62, as shown in FIG. Therefore, since the bottom surface of the drain pan 67 is an inclined surface, the water in the drain pan 67 is less likely to stay and is easily discharged to the outside as compared with the case where the bottom surface of the drain pan 67 is a horizontal surface.

As described above, as shown in FIG. 1, the door 12 has a hinge 12A with respect to the cooler body 11 (storage body) at the right side end (one side end in the left-right direction of the storage). It is mounted rotatably (openable and closable). That is, the hinge 12A constitutes a rotation shaft (rotation center) when the door 12 opens and closes. As shown in FIG. 22, the drain pan 67 includes a drain pan side wall portion 67H. The drain pan side wall portion 67H is a side wall portion forming an end portion (the other end portion in the longitudinal direction of the drain pan 67) opposite to the discharge hole 67A in the longitudinal direction of the drain pan 67. In other words, the discharge hole 67A is provided at the end portion on the hinge 12A side (the end portion closer to the hinge 12A) in the longitudinal direction of the drain pan 67, and the drain pan side wall portion 67H is provided on the hinge 12A in the longitudinal direction of the drain pan 67. It constitutes an end portion on the opposite side (the end portion on the side far from the hinge 12A). That is, the drain pan 67 has an open end on the hinge 12A side and a closed end on the opposite side of the hinge 12A.

Temporarily, the discharge hole 67A is provided at the end opposite to the hinge 12A in the longitudinal direction of the drain pan 67 (in other words, the drain pan side wall portion 67H is not provided, and the end portion of the drain pan 67 opposite to the hinge 12A is provided. In the case of the open configuration), the discharge hole 67A is a hole opened on the side opposite to the hinge 12A. In this case, there is a concern that water may be discharged from the end of the drain pan 67 on the opposite side of the hinge 12A due to the centrifugal force when the door 12 is opened. As in the present embodiment, by providing the drain pan side wall portion 67H forming the end portion on the side opposite to the hinge 12A (the end portion on the side far from the rotation center of the door 12), the centrifugal pan when opening and closing the door 12 is provided. It is possible to suppress the situation where water is discharged from the end of the drain pan 67 opposite to the hinge 12A by force.

As shown in FIG. 18, on the back surface 61A (the surface of the door on the accommodation chamber side) of the first door 61, a box-shaped water receiving member 71 opened upward is provided at a position above the horizontal packing 12H. It is provided. The water receiving member 71 extends in the left-right direction, and is arranged above the opening component 28 as shown in FIG. 26.

A discharge hole 71A for discharging water below the water receiving member 71 is provided. As shown in FIG. 21, the discharge hole 71A is formed by a gap provided between the right end of the rear wall portion 71B of the water receiving member 71 and the right side wall portion 71F of the water receiving member 71. ..

As shown in FIG. 27, the water receiving member 71 is attached to the first door 61 in a downwardly inclined posture from the left side to the right side of the rapid cooling chamber 10 (from the right side to the left side in FIG. 27). Therefore, the upper surface 71E (see FIG. 26) of the bottom wall portion 71C of the water receiving member 71 is designated by the left columnar member 30 (the other columnar member, reference numeral 30L in the following description) of the pair of columnar members 30 and 30. It is an inclined surface that inclines downward toward the columnar member 30R on the right side (in some cases). Further, as shown in FIG. 28, at the rear end portion of the bottom wall portion 71C of the water receiving member 71, an inclined wall portion 71D that inclines downward toward the rear is provided at a portion corresponding to the discharge hole 71A. .. The upper surface 30A of the columnar member 30 is an inclined surface that inclines downward toward the rear.

Therefore, the water received by the water receiving member 71 (for example, the water injected from the injection portion 45 and flowing down the back surface 61A of the first door 61) flows to the columnar member 30R side on the upper surface 71E of the bottom wall portion 71C. After that, it passes through the discharge hole 71A and falls backward from the inclined wall portion 71D on the upper surface of the inclined wall portion 71D. A columnar member 30R is arranged below the discharge hole 71A and the inclined wall portion 71D. Since the upper surface 30A of the columnar member 30R is an inclined surface that inclines downward toward the rear, when the water discharged from the discharge hole 71A falls on the upper surface 30A, the water flows toward the rear (inside the refrigerator). In addition, in FIG. 26 and FIG. 28, such a flow of water is indicated by an arrow L2.

Further, as shown in FIG. 18, on the back surface of the first door 61, longitudinal plate-shaped members 75, 76, 77 are provided on the inner portion of the door packing 12D.

As shown in FIG. 28, the inclined wall portion 77C is arranged above the right end portion of the water receiving member 71. Therefore, the water flowing down the surface of the wall portion 77B is received by the water receiving member 71 through the inclined wall portion 77C.

As shown in FIG. 18, a seat member 70 (closing member) is provided on the surface of the rear wall portion 71B of the water receiving member 71 on the side of the accommodating chamber 15. That is, the seat member 70 is provided on the back surface 61A of the first door 61 via the water receiving member 71. The seat member 70 is arranged so as to hang down from the rear wall portion 71B, and as shown in FIG. 20, the seat member 70 is arranged in the opening 33 in a state where the cart is not inserted, so that the opening 33 is closed. There is. A gap S6 is provided between the lower end of the sheet member 70 and the upper surface 34A of the plate 34. Therefore, when the door 12 is opened and closed, the situation where the seat member 70 rubs against the upper surface 34A can be suppressed. The sheet member 70 has flexibility, and as the sheet member 70, for example, a silicon sheet having excellent cold resistance and chemical resistance can be used, but the sheet member 70 is not limited to this. The material of can be changed as appropriate.

As shown in FIG. 27, the length of the seat member 70 in the left-right direction is set to a value larger than the length L3 between the extending portions 30D and 30E.

The overflow pipe 83E has an L shape and is provided so as to penetrate the side wall portion 81B on the left side of the tank main body portion 81. When the water level in the tank 41 exceeds the upper end of the overflow pipe 83E, the excess water is drained through the overflow pipe 83E. When water is supplied from the water supply valve 49 into the tank 41, for example, after the water level sensor 83A detects a predetermined water level, water is supplied for a predetermined time to overflow the water from the overflow pipe 83E. The valve 49 is closed to stop the water supply to the tank 41, but the present invention is not limited to this.

Further, a tank side drain port 81C for draining the water of the tank 41 is formed in the lower part of the front wall portion 81A. As shown in FIG. 37, a drainage pipe 81D is connected to the tank side drainage port 81C, and the pipe 81D is provided with a valve 81E as shown in FIG. As a result, by opening the valve 81E, the water in the tank 41 can be drained through the drain port 81C on the tank side. Further, as shown in FIG. 35, the bottom wall portion 81F of the tank main body portion 81 is composed of panel members bent at two positions, and has three bottom surfaces 81F1, 81F2, 81F3 having different inclination modes. ing. The bottom surfaces 81F1, 81F2, 81F3 are inclined surfaces that incline downward toward the tank-side drainage port 81C.

Further, in the side wall portion 81B (tank side wall portion), a suction port 81G connected to the pump 43 (shown by a broken line in FIG. 35) is located below the overflow pipe 83 as shown in FIGS. 35 and 36. Is provided. A plate-shaped member 85 is provided in the tank 41 near the suction port 81G. The plate-shaped member 85 includes a facing wall portion 85A arranged to face the bottom wall portion 81F (tank bottom wall portion) at intervals, an extending wall portion 85B extending downward from the side end of the facing wall portion 85A, and a front portion 85B. It has a mounting piece portion 85C attached to the wall portion 81A and a mounting piece portion 85D attached to the side wall portion 81B. The facing wall portion 85A is provided at a position above the suction port 81G, and is arranged to face the bottom surface 81F3 of the bottom wall portion 81F.

Further, as shown in FIG. 36, a gap S4 is provided between the lower end of the extended wall portion 85B and the bottom wall portion 81F. A side wall portion 81B, a bottom wall portion 81F (more specifically, a bottom surface 81F3), and a plate-shaped member 85 form a communication space S5 that communicates with the suction port 81G. The communication space S5 has an opening 86 opened rearward and an opening 87 (gap S4) opened laterally. By operating the pump 43, the water outside the communication space S5 in the tank 41 enters the communication space S5 through either the opening 86 or the opening 87, and then passes through the suction port 81G. It is sucked into the pump 43.

Next, the effect of this embodiment will be described. In the present embodiment, the gap between the second door 62 and the front surface 29A (front surface of the bottom wall portion) of the extension portion 29 can be filled with the packing 31 when the cart is not accommodated. If the water from the injection unit 45 drips below the packing 31 through a gap between the packing 31 and the seat member 12B, for example, the dripping water can be received by the drain pan 67 and leaks out of the refrigerator. It is possible to prevent the water from falling onto the floor surface 14A. Further, in the above configuration, when the door 12 is closed, the second door 62 is displaced forward relative to the first door 61, so that the connecting portion 21 (pillar 22) of the cart 13 and the second door 62 Can suppress the situation of interference. If the drain pan provided on the bottom wall portion 15F of the cooling cabinet main body 11 is configured to receive water dripping downward from the front end of the bottom wall portion 15F, the drain pan 67 protrudes from the front surface of the bottom wall portion 15F. Therefore, there is a concern that the cart 13 and the drain pan 67 may interfere with each other. In the above configuration, since the drain pan 67 is provided on the second door 62, it can be displaced forward relative to the first door 61 together with the second door 62, and the drain pan 67 and the connecting portion 21 of the cart 13 can be displaced. It is possible to suppress the situation of interference.

Further, a main body side drain pan 68 provided in the cooler main body 11 is provided, and the drain pan 67 has a long longitudinal shape in the left-right direction of the rapid cooler 10, and one end portion of the drain pan 67 in the longitudinal direction is inside the drain pan 67. A drain hole 67A for discharging water below the drain pan 67 is provided, and the drain pan 68 on the main body side is arranged at a position that does not overlap with the cart 13 in the front view. It is placed above.

The water received by the drain pan 67 goes to the drain pan 68 on the main body side through the discharge hole 67A. Therefore, the situation where water overflows from the drain pan 67 can be suppressed. As a result, the amount of water that can be received can be increased as compared with the configuration including only the drain pan 67. Further, since the drain pan 68 on the main body side is arranged at a position that does not overlap with the cart 13 in the front view, it is possible to suppress a situation in which the cart 13 is hindered from being taken in and out. The front view is a state in which the rapid cooling cabinet 10 is viewed from the front, and the left-right direction is a left-right direction when the rapid cooling cabinet 10 is viewed from the front. Further, since the drain pan 67 is displaced when the door 12 is opened and closed, it is difficult to connect the drain pipe to the drain pan 67. On the other hand, since the drain pan 68 on the main body side is provided in the cooling cabinet main body 11 and does not displace when the door 12 is opened and closed, the drain pipe (pipe 68B) can be easily connected, and the drain pan 68 on the main body side can be easily connected. Water can be drained through the pipe 68B.

Further, the drain pan 67 is made of metal, and a synthetic resin projecting portion 69 projecting toward the connecting portion 21 side is provided on the surface 67B of the drain pan 67 on the accommodation chamber side. By interposing the protruding portion 69 between the connecting portion 21 and the drain pan 67, it is possible to suppress a situation in which the metal drain pan 67 directly contacts the connecting portion 21 of the cart 13 and a metallic sound is generated.

Further, a tank 41 provided on the lower surface 11A of the bottom wall portion 15F and connected to a drainage port 15G formed through the bottom wall portion 15F, a pump 43 for supplying water in the tank 41 to the injection portion 45, and a tank. A tank cover 84 that covers an electric component (front end portions 83A1, 83B1, 83C1, 83D1) provided on the front surface 41A of the 41 is provided. The water from the injection unit 45 is stored in the tank 41 through the drain port 15G, and the water stored in the tank 41 is supplied to the injection unit 45 by the pump 43. As a result, water can be circulated between the injection unit 45 and the tank 41, and the inside of the storage chamber 15 can be cleaned while reducing the supply of water from the outside (water supply or the like). Further, by providing the tank cover 84, it is possible to more reliably suppress the situation where water is splashed on the electric parts (front end portions 83A1, 83B1, 83C1, 83D1) provided on the front surface 41A of the tank 41.

Further, the side wall portion 81B of the tank 41 is provided with a suction port 81G connected to the pump 43, and a plate-shaped member 85 is provided in the tank 41 at a position above the suction port 81G. The side wall portion 81B, the bottom wall portion 81F, and the plate-shaped member 85 form a communication space S5 that communicates with the suction port 81G.

When the pump 43 operates, the water in the tank 41 is sucked into the pump 43 through the suction port 81G. Along with this, a vortex may be generated due to the flow of water in the tank 41. When such a vortex reaches the suction port 81G, air is sucked into the suction port 81G together with water. In the above configuration, the plate-shaped member 85 constitutes a communication space S5 that communicates with the suction port 81G. As a result, the water in the tank 41 goes to the suction port 81G via the communication space S5. If the water is directed to the suction port 81G via the communication space S5, the water path from the water surface to the suction port 81G can be lengthened by the amount of the communication space S5. Generally, a vortex is generated from the water surface along the flow of water. Therefore, by lengthening the water path from the water surface to the suction port 81G, it is possible to suppress the situation where the generated vortex reaches the suction port 81G. ..

Assuming that the plate-shaped member 85 is not arranged, as shown in FIG. 36, the vortex T1 (the water surface of the water in the tank 41) is directed toward the suction port 81G from a position close to the suction port 81G. (Refer to the arrow line in FIG. 36) may occur, and the lower end of the vortex T1 may reach the suction port 81G. On the other hand, in the present embodiment, the vortex T2 (see the arrow in FIG. 36) is generated from the portion of the water surface W1 avoiding the plate-shaped member 85 toward the opening 87 (or the opening 86). , The situation where the lower end of the vortex T2 reaches the suction port 81G can be suppressed. That is, the lower end of the vortex can be kept away from the suction port 81G by the amount of the plate-shaped member 85. As a result, even when the water level in the tank 41 is low, it is possible to suppress a situation in which air is sucked into the suction port 81G together with the water in the tank 41 and heads toward the pump 43 (so-called air shaving). The water of 41 can be more reliably supplied to the injection unit 45 (and the injection unit 46).

Further, the plate-shaped member 85 has an extended wall portion 85B, and the rigidity can be further increased. The communication space S5 has an opening 86 opened rearward and an opening 87 (gap S4) opened laterally, and the width (length in the vertical direction) of the opening 86 is determined. It is assumed to be larger than the width (length in the vertical direction) of the opening 87. As a result, it is possible to facilitate the flow of water as compared with the case where the width of the opening 86 is the same as the width of the opening 87, and it is possible to suppress a situation in which a load is applied to the pump 43.

Further, in the present embodiment, an opening component 28 constituting an opening 33 capable of inserting at least a part (base 24) of the cart main body 20 from the front, a door 12 capable of opening and closing the storage chamber 15, and a door 12 capable of opening and closing the storage chamber 15 A cart not inserted state (injection portion 45 provided in the storage chamber 15 capable of injecting water) and a cart not inserted state provided on the back surface 61A of the first door 61 and the base 24 of the cart 13 is not inserted in the opening 33 ( A sheet member 70 that closes the opening 33 in a cart unaccommodated state) is provided.

With such a configuration, the cart body 20 can be positioned by inserting the base 24 of the cart body 20 into the opening 33. Further, in the state where the cart 13 is not inserted into the opening 33, since the opening 33 is closed by the sheet member 70, water from the injection portion 45 passes through the opening 33 and is outside the refrigerator (mainly a cooling cabinet). The situation of leaking to the front of the main body 11) can be suppressed. Further, since the seat member 70 is provided on the door 12, the opening 33 is opened as a result of being separated from the opening 33 by opening the door 12. As a result, it is not necessary to remove the seat member 70 from the opening 33 when the cart main body 20 is inserted into the opening 33, and workability can be improved.

Further, the seat member 70 is arranged in the opening 33 in a state where the cart is not inserted, and the upper surface 34A of the plate 34 (the bottom surface of the inner surface of the opening 33 arranged below the seat member 70) is arranged toward the rear. It is an inclined surface that slopes downward. By arranging the sheet member 70 in the opening 33, the opening 33 can be closed more reliably. However, if the water flowing down the surface of the sheet member 70 collects on the upper surface 34A (bottom surface of the opening 33), there is a concern that the water leaks in front of the opening 33. Therefore, if the upper surface 34A is an inclined surface, the water on the upper surface 34A can easily move toward the rear (inside the accommodation chamber 15), and the situation where water accumulates can be suppressed.

Further, the seat member 70 is arranged in the opening 33 when the cart is not inserted, and a groove 34B extending in the front-rear direction is provided on the upper surface 34A (bottom surface of the opening 33) in the left-right direction of the rapid cooling cabinet 10. It is formed in the form of multiple lines along the line. By arranging the sheet member 70 in the opening 33, the opening 33 can be closed more reliably. However, if the water flowing down the surface of the sheet member 70 collects on the upper surface 34A, there is a concern that the water may leak to the front of the opening 33. Therefore, by providing a plurality of groove portions 34B on the upper surface 34A, the water on the upper surface 34A can easily flow along the groove portions 34B. As a result, it is possible to more reliably suppress the situation where water accumulates on the upper surface 34A.

Further, the cooling cabinet main body 11 includes a ceiling wall portion 15E constituting the accommodation chamber 15, and the injection portion 45 is provided on the lower surface 15K of the ceiling wall portion 15E, and can inject water at least toward the front. An extension member 73 extending in the left-right direction of the rapid cooling chamber 10 is interposed between the injection portion 45 and the upper end portion of the door 12. By providing the extension member 73, it is possible to suppress a situation in which water from the injection portion 45 is directly applied to the upper end portion of the door 12. As a result, it is possible to suppress a situation in which water leaks out of the refrigerator from between the upper end of the door 12 and the cooling cabinet main body 11 (for example, between the door packing 12D and the cooling cabinet main body 11, see FIG. 10).

Further, the extension member 73 has an upper surface 73B1 that inclines downward toward the rear. When the water from the injection unit 45 bounces off the upper surface 73B1, the bounced water can be directed backward. Therefore, it is possible to prevent the water bounced off by the extension member 73 from leaking out of the refrigerator toward the front.

Further, the cooling cabinet main body 11 has side wall portions 15D and 15H constituting the inner surface of the accommodating chamber 15, and has an end portion on the side wall portion 15D side (one end portion on the side wall portion side) in the extension direction of the extension member 73. A gap S2 is provided between the side wall portion 15D and the side wall portion 15H, and a gap S3 is provided between the end portion on the side wall portion 15H side in the extension direction of the extension member 73 and the side wall portion 15H.

If one end of the extension member 73 and the side wall portion 15D are in contact with each other, the water sprayed forward from the injection portion 45 and toward the side wall portion 15D is blocked by one end portion of the extension member 73, and the side wall portion 15D There is a concern that water does not reach in front of the extension member 73 (for example, the plate portion 73B). By providing a gap S2 between one end of the extension member 73 and the side wall portion 15D, water W2 (see FIG. 33) can be directed forward through the gap S2. As a result, it is possible to suppress a situation in which water does not reach a part of the surface of the side wall portion 15D (for example, the portion indicated by reference numeral R1 in FIG. 33), and it is possible to more reliably clean the surface of the side wall portion 15D. Further, by providing the gap S3 between the other end of the extension member 73 and the side wall portion 15H, the surface of the side wall portion 15H (more specifically, the front portion of the extension member 73) can be cleaned more reliably. be able to.

Further, a box-shaped water receiving member 71 which is provided on the surface of the door 12 on the side of the accommodation chamber 15 and extends in the left-right direction of the rapid cooling cabinet 10 and is opened upward is provided, and the opening constituent member 28 is a panel member.

In the water receiving member 71, the water in the water receiving member 71 is watered at a position where the water receiving member 71 is arranged above the columnar member 30R of one of the pair of columnar members 30 and 30. A discharge hole 71A for discharging water is provided below the receiving member 71, and the upper surface 30A of the columnar member 30 is an inclined surface that inclines downward toward the rear.

When the water from the injection unit 45 flows down the back surface of the door 12, the water that has flowed down can be received by the water receiving member 71. Then, the water received by the water receiving member 71 is discharged from the discharge hole 71A. Here, the discharge hole 71A is arranged above the columnar member 30R, and is arranged so as to avoid the opening 33. Therefore, it is possible to prevent the water discharged from the discharge hole 71A from leaking to the outside of the refrigerator through the opening 33. Further, since the upper surface 30A of the columnar member 30R is an inclined surface that inclines downward as it goes backward, when the water discharged from the discharge hole 71A falls to the upper surface 30A, it goes backward (inside the refrigerator). , The situation of leaking to the outside of the refrigerator can be suppressed more reliably.

Further, the bottom wall portion 71C of the water receiving member 71 is an upper surface that is an inclined surface that inclines downward from the left columnar member 30 (the other columnar member) of the pair of columnar members 30 and 30 toward the right columnar member 30R.

It is provided so as to extend in the direction. When the water from the injection unit 45 flows down the back surface 17B (the surface on the cooler side) of the door 17A, the water that has flowed down can flow backward (inside the refrigerator) by the inclined surface 72A of the inclined surface constituent member 72. As a result, it is possible to prevent water from leaking from the lower end of the door 17A to the outside of the refrigerator.

<Embodiment 2>
Next, Embodiment 2 of the present invention will be described with reference to FIG. 38. The same parts as those in the above embodiment are designated by the same reference numerals, and duplicate description will be omitted. In the present embodiment, the configuration of the extension member interposed between the injection portion 45 (see FIG. 10) and the upper end portion of the door 12 is different from that of the above embodiment. As shown in FIG. 38, the extension member 273 of the present embodiment has a plate shape, and the first plate portion 273A attached to the lower surface of the ceiling wall portion 15E and the first plate portion 273A are rearward from the rear end.

Further, the second plate portion 273B has an extension member side inclined surface 273B1 that inclines downward toward the rear. The fourth plate portion 273D is arranged to face the facing wall portion 75A of the plate-shaped member 75.

In the present embodiment, by providing the fourth plate portion 273D arranged on the door 12 side of the second plate portion 273B, the extension member is compared with the configuration in which only the first plate portion 273A and the second plate portion 273B are provided. Therefore, the gap between the extension member 273 and the door 12 can be made smaller. As a result, water from the injection unit 45 (see FIG. 10) (or steam obtained by evaporating the water) passes through the gap between the extension member 273 and the door 12 (more specifically, the gap between the extension member 273 and the facing wall portion 75A). It is possible to suppress the situation of leaking to the outside of the refrigerator. Further, since the third plate portion 273C connecting the fourth plate portion 273D and the first plate portion 273A is inclined downward as it goes forward, the water injected from the injection portion 45 is applied to the back surface of the door 12 or the like. Even when the water bounces off the upper surface 273C1, it is possible to prevent water from accumulating on the upper surface 273C1 of the third plate portion 273C.
