(Effects of Example)
Next, the operation of the structure of the door with a window of the storage according to the embodiment will be described. First, a procedure for manufacturing the door 16 according to the embodiment will be described. The opening edge 20 of the exterior plate 18 is inserted into the slit 33 of the first packing 30, and the first packing 30 is attached over the entire circumference of the opening edge 20 of the exterior plate 18. In this state, the multi-layer glass plate 26 in which the outer plate 18 is positioned and placed on a jig (not shown) so as to open upward, and the code heater 47 is adhered to the outer surface of the outer glass plate 27 is used as the first packing. 30 and pipes 51, 51 through which the heater lead 53 is inserted. At this time, the first and second fin portions 41 and 43 formed on the entire circumference of the first packing 30 are in close contact with the outer glass plate 27. Next, the opening edge 24 of the interior plate 22 is inserted into the slit 33 of the second packing 31, and the second packing 31 is attached over the entire circumference of the opening edge 24 of the interior plate 22, The interior plate 22 to which the two packings 31 are attached is aligned with the rear opening of the exterior plate 18. At this time, the first and second fin portions 41 and 43 formed on the entire circumference of the second packing 31 are in close contact with the inner glass plate 28. Then, with the interior plate 22 fixed with a jig (not shown), a required amount of foaming liquid is injected between the exterior plate 18 and the interior plate 22 through a hole (not shown) formed in the exterior plate 18. Foam. Thereby, the heat insulation door 16 provided with the glass window is manufactured.

  In this manner, the first packing 30 is attached to the opening edge 20 of the exterior plate 18 in the door 16 to maintain airtightness with the outer glass plate 27, and the second packing 31 is provided to the opening edge 24 of the interior plate 22. Is attached so that the airtightness with the inner glass plate 28 is maintained, so that the shape of the glass window is determined by the shapes of the first and second openings 19 and 23 provided in the exterior plate 18 and the interior plate 22. obtain. That is, by forming the corners of the first and second openings 19 and 23 opened in the exterior plate 18 and the interior plate 22 in a circular arc shape, the multilayer facing the first and second openings 19 and 23 is formed. The corner of the glass plate 26 (that is, the glass window) can be formed in an arc shape. Moreover, the door which concerns on a prior art needs to each attach a packing to four sides of the glass plate formed in the rectangular shape. On the other hand, in the door 16 according to the embodiment, it is only necessary to attach the first packing 30 to the opening edge 20 of the exterior plate 18 and attach the second packing 31 to the opening edge 24 of the interior plate 22. The number of parts can be reduced to reduce the cost, and the assembly work can be facilitated.

  Further, each of the first and second packings 30 and 31 is formed in a hollow shape having a space portion 35a over the entire length in the longitudinal direction thereof, so that the first and second packings 30 and 31 can be easily made. It can be curved to. Accordingly, each of the first and second packings 30 and 31 can be easily attached along the open end edges 20 and 24 of the inner and outer plates 18 and 22 which are arcuate. Furthermore, by forming the space portion 35a in each of the first and second packings 30 and 31, the base portion 35 of each packing 30 and 31 is elastically deformed, and the multilayer glass plate 26 and the inner and outer plates 18 and 22 are formed. Even if there is an error in the thickness dimension, the packings 30 and 31 can be brought into close contact with the multilayer glass plate 26.

  Further, when the door 16 is manufactured, the first and second fin portions 41 and 43 formed in the first and second packings 30 and 31 are elastically deformed so as to be in close contact with the multilayer glass plate 26. Therefore, the airtightness between the packings 30 and 31 and the multilayer glass plate 26 can be more reliably maintained. That is, the first fin portion 41 facing the outside of the openings 19 and 23 (the heat insulating material 25 side) is in close contact with the multilayer glass plate 26, so that the foaming liquid is injected between the exterior plate 18 and the interior plate 22. In this case, the foaming liquid can be prevented from leaking, and the second fin portion 43 facing the inside of the openings 19 and 23 is brought into close contact with the multilayer glass plate 26, so that water, dust, etc. can enter the door from the outside. Intrusion can be prevented. Further, in a state where the opening edges 20 and 24 of the inner and outer plates 18 and 22 are inserted into the slits 33 of the first and second packings 30 and 31, elastic pieces formed on the tongue 45 of the packings 30 and 31, respectively. 45a adheres to the outer surfaces of the inner and outer plates 18, 22. For this reason, the airtightness between the respective packings 30 and 31 and the inner and outer plates 18 and 22 is further improved, and it is possible to more reliably prevent problems such as leakage of foaming liquid and intrusion of water and dust. .

  Furthermore, in the embodiment, a stepped portion 22 b that is recessed toward the exterior plate 18 is formed on the opening edge 24 side of the interior plate 22, and the second packing 31 is attached to the opening edge 24 of the interior plate 22. The second packing 31 is configured not to protrude inward from the interior plate 22. Thereby, there is an advantage that the visibility in the warehouse is improved and the capacity in the warehouse can be increased.

  In addition, since the inclined guide pieces 39, 39 are formed on the base portion 35 of the packings 30, 31, when the packings 30, 31 are attached to the opening edges 20, 24 of the corresponding inner and outer plates 18, 22, The opening edges 20 and 24 are guided to the slits 33 of the corresponding packings 30 and 31 so that they can be easily attached. Further, the base portions 35, 35 of the first and second packings 30, 31 are provided with restricting pieces 37, 37 projecting into the slits 33, 33 over the entire length thereof, so as to form a so-called wedge shape. Thus, in a state where the packings 30 and 31 are attached to the opening edges 20 and 24 of the inner and outer plates 18 and 22, the first and second projecting portions 18 a and 22 a formed on the inner and outer plates 18 and 22, respectively. , Since it is possible to prevent the packings 30, 31 from falling off the opening edges 20, 24 of the inner and outer plates 18, 22 by engaging with the regulating pieces 37, 37 of the packings 30, 31. There is an advantage that the assembling work can be easily performed.

  Further, when the cord heater 47 for preventing condensation is adhered to the inner surface side of the outer glass plate 27 (the surface facing the inner glass plate 28), the heat of the cord heater 47 is increased by the inner glass plate. It is easy to be transmitted to the interior via the door 28 and becomes a factor that hinders cooling in the interior. Further, when the cord heater 47 is provided on the inner surface side of the outer glass plate 27, it is conceivable to provide the cord heater 47 inside the spacer 29 in order to prevent a decrease in cooling performance. The heat of the cord heater 47 cannot be efficiently transmitted to the outer glass plate 27, and the amount of heat generated by the cord heater 47 needs to be increased. On the other hand, in the door 16 of the embodiment, the code heater 47 is configured to come into contact with the outer surface side of the outer glass plate 27 in the multilayer glass plate 26. The impact can be minimized and does not hinder cooling in the cabinet. Further, by covering the cord heater 47 with the aluminum foil tape 49, there is an advantage that the heat generated by the cord heater 47 can be efficiently transmitted to the outer glass plate 27 and the occurrence of condensation can be suppressed.
