JP, 2014-215019, A

In the above configuration, the opening is closed by the cart when the cart is stored in the storage. On the other hand, when the cart is not placed in the refrigerator, there is a concern that the air in the refrigerator may leak to the outside through the opening. For this reason, it is required to prevent the air in the refrigerator from leaking out of the refrigerator when the cart is not placed in the refrigerator.

The present invention has been completed based on the above circumstances, and it is an object of the present invention to suppress the situation in which the air inside the refrigerator leaks to the outside of the refrigerator when the cart is not placed inside the refrigerator.

In order to solve the above problems, the storage of the present invention is a box-shaped storage main body having a storage chamber that is opened forward and can store a part of a cart, and a front end of a bottom wall portion of the storage main body. An opening forming member which is provided in a portion and which forms an opening through which the part of the cart can be inserted from the front, wherein the cart is formed by the opening edge of the opening in the opening forming member. An opening forming member that restricts the rearward displacement of the cart by receiving it from the rear, a door that can open and close the storage chamber, a seal member provided on the back surface of the door, and the part of the cart. A cover member that closes the opening in a state where the cover member is not inserted into the opening, the cover member includes a first wall portion that comes into contact with the seal member from the rear, and a first wall portion. And a second wall portion which is arranged rearwardly and which is fitted into the opening portion.

In a state where the cart is not accommodated in the accommodation chamber (inside the compartment), the opening is closed by the second wall portion of the cover member, so that it is possible to prevent the air in the accommodation chamber from leaking out of the compartment through the opening. it can. Further, since the cover member includes the first wall portion that comes into contact with the door-side seal member, it is possible to suppress the situation where the air in the storage chamber leaks to the outside of the refrigerator through the gap between the door and the cover member. Further, a wall portion (second wall portion) that closes the opening in the cover member is arranged rearward (inside the refrigerator) from the first wall portion. When there is a temperature difference between the inside and outside of the refrigerator, there is a concern that dew condensation may occur on the surface of the cover member. Since the second wall portion is relatively inside the storage compartment, when dew condensation occurs on the second wall portion, the condensed water easily drops into the storage compartment. That is, it is possible to suppress the situation in which the condensed water falls outside (forward) compared to the configuration in which the “wall portion that closes the opening” is provided at the position of the first wall portion instead of providing the second wall portion.

The opening forming member includes a first extending portion extending in the left-right direction of the storage, and a pair of second extending portions rising upward from both ends of the first extending portion in the left-right direction. A main body side seal member provided on the front surface of the second extended portion, the main body side seal member constituting a part of the opening edge portion of the opening portion, and the cover member. A third wall portion that extends rearward from the upper end of the first wall portion and is connected to the upper end of the second wall portion at the rear end, the third wall portion including both of the pair of main body side seal members. Is arranged so as to cover from above. By receiving the cart from the rear by the main body side seal member, it is possible to suppress the situation in which a gap is created between the cart and the opening forming member. Further, by covering the main body side sealing member from above with the upper wall portion, it is possible to improve the design.

According to the present invention, it is possible to suppress the situation in which the air inside the refrigerator leaks to the outside of the refrigerator when the cart is not placed inside the refrigerator.

The cooler 35 is for cooling the accommodation chamber 15 (inside the storage), and is arranged on the left side of the internal fan 36. The cooler 35 constitutes a refrigeration cycle by being circulated and connected to a refrigerating device (compressor and condenser) not shown provided outside through a refrigerant pipe. Each device (compressor, condenser, condenser fan, etc.) that constitutes the refrigerating apparatus may be arranged in, for example, a machine room 38 provided above the cooling cabinet body 11.

In the cooling operation for cooling the accommodation chamber 15, when the refrigerating device and the internal fan 36 are operated, the air in the accommodation chamber 15 is sucked into the casing 37 and is cooled when passing through the cooler 35, thereby cooling the air. Then, after the cold air blown out from the casing 37 to the left side hits the left side wall portion 17B forming the installation chamber 17, it is sent to the accommodation chamber 15 so as to wrap around the casing 37. The accommodation chamber 15 is cooled by such continuous circulation of air. A heater 39 is provided on the right side surface of the cooler 35. The heater 39 is used when performing a drying operation for drying the inside of the refrigerator. Such a drying operation is performed, for example, after cleaning the inside of the refrigerator.

As described above, in the present embodiment, the door packing 12D closes the gap between the door 12 and the cooling cabinet body 11, thereby suppressing the situation in which the cold air in the storage chamber 15 leaks to the outside of the cabinet. .. In the cart accommodation state, the lateral packing 12H of the door packing 12D is configured to fill the gap between the lateral packing 12H and the plate portion 23 of the cart 13. However, in the case of performing the pre-cooling operation, the storage chamber 15 may be cooled without mounting the cart 13 on the refrigerating box main body 11, and such a cart unacquired state (the cart main body 20 is inserted into the opening 33). In a state where the opening 33 is not provided, the plate portion 23 for closing the opening 33 does not exist. Therefore, as shown in FIG. 10, the quick cooling box 10 of the present embodiment includes a cover member 60 that closes the opening 33 instead of the plate 23 in the state where the cart is not in use. Next, the configuration of the cover member 60 will be described.

As shown in FIG. 11, the cover member 60 includes a front wall portion 61 (first wall portion) arranged on the front side and a rear wall portion 62 (second wall portion) arranged rearward of the front wall portion 61. ), an upper wall portion 63 (third wall portion) extending rearward from the upper end of the front wall portion 61 and connected to the upper end of the rear wall portion 62 at the rear end, and a handle provided on the upper surface of the upper wall portion 63. And a section 64. As shown in FIG. 12, the front surface of the front wall portion 61 is in contact with the seat member 12B from the rear. In other words, the horizontal packing 12H is pressed against the front surface of the front wall portion 61 via the sheet member 12B. The front wall portion 61 has a plate shape that is long in the left-right direction, and as shown in FIGS. 13 and 14, the rear surface (the upper surface in FIGS. 13 and 14) of the front wall portion 61 has a pair of left and right packings 32, It is configured to come into contact with both of 32. That is, in this embodiment, the horizontal packing 12H, the sheet member 12B, the front wall portion 61, the packing 32, and the rear wall portion 62 are arranged in this order from the outside of the refrigerator.

The rear wall portion 62 has a plate shape that is long in the left-right direction, and is arranged between the pair of extending portions 30 and 30 as shown in FIGS. 13 and 15. That is, the rear wall 62 is fitted in the opening 33. As a result, the opening 33 is closed by the rear wall 62. As shown in FIG. 10, the upper wall portion 63 is set to have a length in the left-right direction that spans the pair of packings 32, 32. As a result, one end portion of the upper wall portion 63 in the longitudinal direction is arranged so as to cover the left packing 32 (further, the recessed portion 30A in which the packing 32 is fitted, see FIG. 6) from above. The other end of 63 in the longitudinal direction is arranged so as to cover the right packing 32 from above.

When the cart 13 is housed in the housing chamber 15 after the pre-cooling operation is completed, the worker opens the opening 33 by removing the cover member 60 from the opening forming member 28. Since the cover member 60 is provided with the handle portion 64, an operator can easily remove the cover member 60 from the opening component member 28 by gripping the handle portion 64.

Next, the effect of this embodiment will be described. In the present embodiment, since the opening 33 is closed by the rear wall portion 62 of the cover member 60 in a state where the cart 13 is not stored in the storage chamber 15 (inside the storage chamber), the storage chamber is opened through the opening 33. It is possible to suppress the situation where the air of 15 (cold air during the cooling operation or steam during the drying operation) leaks out of the refrigerator. Further, since the cover member 60 includes the front wall portion 61 that comes into contact with the door-side sheet member 12B, it is possible to suppress the situation where the air in the storage chamber 15 leaks to the outside of the refrigerator through the gap between the door 12 and the cover member 60. In addition, a wall portion (rear wall portion 62) that closes the opening 33 in the cover member 60 is arranged rearward (inside the refrigerator) from the front wall portion 61.

When there is a temperature difference between the inside and the outside of the refrigerator, there is a concern that dew condensation may occur on the surface of the cover member 60. Since the rear wall portion 62 is relatively inside the compartment with respect to the front wall portion 61, when dew condensation occurs on the rear wall portion 62, the condensed water falls into the compartment (on the extension portion 29). easy. That is, as compared with the configuration in which the "wall portion that closes the opening 33" is provided at the position of the front wall portion 61 instead of providing the rear wall portion 62, it is possible to suppress the situation in which the condensed water falls outside the storage (forward).

Further, by receiving the cart 13 (the plate portion 23) from the rear side by the packing 32, it is possible to suppress a situation in which a gap is created between the cart 13 and the opening forming member 28. Further, by covering the packing 32 from above with the upper wall portion 63, it is possible to improve the design.
