JP 2014-215019 A

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

SUMMARY OF THE INVENTION The present invention has been completed based on the above circumstances, and an object of the present invention is to prevent the air inside the refrigerator from leaking out of the refrigerator when the cart is not placed inside the refrigerator.

In order to solve the above-mentioned problems, the storage of the present invention comprises a box-shaped storage body having a forwardly opened storage chamber capable of storing a part of the cart, and a front end of the bottom wall of the storage body. an opening constituting an opening into which the part of the cart can be inserted from the front; An opening forming member for restricting the cart from being displaced rearward by being received from the rear, a door capable of opening and closing the storage chamber, a sealing member provided on the back surface of the door, and the portion of the cart. a cover member that closes the opening when the is not inserted into the opening, wherein the cover member includes a first wall that contacts the seal member from behind; and a second wall portion that is arranged rearwardly with respect to the opening and is fitted into the opening.

When the cart is not stored in the storage chamber (inside the storage), the opening is blocked by the second wall of the cover member, thereby preventing air from leaking out of the storage chamber through the opening. can. In addition, since the cover member has the first wall portion that abuts against the door-side seal member, it is possible to prevent air from leaking out of the storage chamber through the gap between the door and the cover member. In addition, a wall portion (second wall portion) that closes the opening of the cover member is arranged behind the first wall portion (inside the chamber). If there is a temperature difference between the inside and outside of the refrigerator, there is concern that dew condensation may occur on the surface of the cover member. Since the second wall portion is located relatively inside the chamber, when dew condensation occurs on the second wall portion, the condensed water tends to fall into the chamber. That is, compared to a configuration in which a “wall portion that closes the opening” is provided at the position of the first wall portion instead of providing the second wall portion, it is possible to prevent the condensed water from falling outside (to the front) of the chamber.

Further, the opening forming member includes a first extending portion extending along the left-right direction of the storage, a pair of second extending portions rising upward from both ends of the first extending portion in the left-right direction, a body-side sealing member provided on the front surface of the second extending portion, wherein the body-side sealing member constitutes a part of the opening edge of the opening; and the cover member is a third wall portion extending rearward from the upper end of the first wall portion and connected to the upper end of the second wall portion at a rear end thereof; are arranged in such a way as to cover them from above. By receiving the cart from the rear side with the body-side sealing member, it is possible to suppress the occurrence of a gap between the cart and the opening forming member. Further, by covering the body-side sealing member from above with the upper wall portion, it is possible to enhance the design.

As shown in FIG. 7, a cooling unit 16 is installed in the installation room 17 . The cooling unit 16 includes two coolers 35 (evaporators) and three internal fans 36 housed in a casing 37 to form a unit. The cooler 35 is for cooling the storage chamber 15 (inside the refrigerator), and is arranged on the left side of the inner fan 36 . The cooler 35 constitutes a refrigerating cycle by being circulatingly connected to a refrigerating device (a compressor and a condenser) provided outside (not shown) via a refrigerant pipe. Each device (compressor, condenser, condenser fan, etc.) constituting the refrigeration system may be arranged in a machine room 38 provided above the refrigerator body 11, for example.

In the cooling operation for cooling the storage chamber 15, when the refrigerating device and the internal fan 36 are operated, the air in the storage chamber 15 is sucked into the casing 37, and is cooled when passing through the cooler 35, resulting in cold air. Then, the cool air blown out to the left from the casing 37 hits the left wall portion 17B constituting the installation chamber 17, and is sent into the storage chamber 15 so as to go around the casing 37. As shown in FIG. The storage chamber 15 is cooled by the continuous air circulation. A heater 39 is provided on the right side of the cooler 35 . The heater 39 is used, for example, when performing a drying operation for drying the inside of the refrigerator.

As described above, in the present embodiment, the gap between the door 12 and the refrigerator main body 11 is closed by the door packing 12D, thereby suppressing the leakage of cold air from the storage chamber 15 to the outside. . In the cart accommodated state, the lateral packing 12H of the door packing 12D fills the gap between the plate portion 23 of the cart 13 and the door packing 12D. However, when the pre-cooling operation is performed, the storage chamber 15 may be cooled without attaching the cart 13 to the refrigerator main body 11. In the state where the opening 33 is not closed, the plate portion 23 for closing the opening 33 does not exist. For this reason, as shown in FIG. 10, the rapid cooling warehouse 10 of this embodiment includes a cover member 60 that closes the opening 33 in place of the plate portion 23 when the cart is not accommodated. Next, the structure of the cover member 60 will be described.

In other words, the lateral packing 12H is pressed against the front surface of the front wall portion 61 via the sheet member 12B. 13 and 14, the rear surface of the front wall portion 61 (the upper surface in FIGS. 13 and 14) is provided with a pair of left and right packings 32, 32 are in contact with each other. 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 outer side of the chamber.

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

When storing the cart 13 in the storage chamber 15 after the pre-cooling operation or the like is completed, the operator opens the opening 33 by removing the cover member 60 from the opening forming member 28 . Since the cover member 60 includes the handle portion 64 , the operator can easily remove the cover member 60 from the opening forming member 28 by gripping the handle portion 64 .

Next, the effects of this embodiment will be described. In the present embodiment, the rear wall 62 of the cover member 60 closes the opening 33 when the cart 13 is not stored in the storage chamber 15 (inside the storage). 15 air (cold air during cooling operation and steam during drying operation) can be prevented from leaking out of the refrigerator. Further, since the cover member 60 has the front wall portion 61 that abuts on the sheet member 12B on the door side, it is possible to prevent air from leaking out of the storage chamber 15 through the gap between the door 12 and the cover member 60 . A wall portion (rear wall portion 62 ) that closes the opening 33 in the cover member 60 is arranged behind the front wall portion 61 (inside the refrigerator).

If there is a temperature difference between the inside and outside of the refrigerator, there is concern that dew condensation may occur on the surface of the cover member 60 . Since the rear wall portion 62 is located inside the chamber relative to the front wall portion 61, when condensation occurs on the rear wall portion 62, the condensed water drops into the chamber (on the extended portion 29). easy. That is, compared to a configuration in which "a 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 prevent the condensed water from falling outside (to the front) of the refrigerator.

Moreover, by receiving the cart 13 (plate portion 23 ) from the rear side with the packing 32 , it is possible to prevent a gap from occurring between the cart 13 and the opening forming member 28 . Further, by covering the packing 32 from above with the upper wall portion 63, the design can be enhanced.
