Problems solved by technology

[0007] According to the door device described in the aforementioned Patent Document 1, since the outside air is arranged outside the storage of the fin portion, when the temperature of the fin portion drops below the dew condensation temperature, condensation occurs on the surface of the fin portion outside the storage. , there may be a situation where dew condensation water drips onto the floor where the cooling storage is installed
However, in the refrigerator of the cooling storage, the cold air may flow from the inside of the refrigerator toward the fins.

Embodiment approach 1

[0028] by Figure 1 to Figure 5 The first embodiment of the present invention will be described. First, the overall structure of the cooling store in this embodiment will be described. Here, as a cooling storage, a 4-door refrigerator 1 without a center pillar will be described as an example. Such as figure 1 As shown, the refrigerator 1 includes: a storage main body 10; on the front surface of the storage main body 10 ( figure 1 The front side of the paper in the middle) two sets of door devices 11 arranged up and down; a machine room 12 arranged above the storage body 10; and leg bodies 13 arranged at the four corners of the bottom surface of the storage body 10.

[0029] Such as figure 2 As shown, the storage main body 10 is composed of a heat-insulating box that is open to the front side (the front side of the paper), and the opening 10A is formed two up and down by a columnar member 21. It should be noted that each storage compartment 14 is not provided with a columnar me...

Embodiment approach 2

[0058] Next, pass Image 6 The second embodiment of the present invention will be described. In this embodiment, the structure of the center seal is different from the above-mentioned embodiment. It should be noted that the same parts as those in the above-mentioned embodiment are denoted by the same reference numerals, and repeated descriptions are omitted. In this embodiment, as Image 6 As shown, the second lip portion 145 of the central seal 140 has a linear shape extending from the support portion 43. In addition, the sealing body 41, the fin portion 42, the support portion 43, and the base end portion 145B of the second lip portion 145 are integrally formed with a soft resin (for example, an olefin-based elastomer). On the other hand, the front end 145A of the second lip 145 is formed of a hard resin with higher rigidity than the base end 145B. As the material of the tip 145A, rigid polypropylene can be exemplified. It should be noted that such a central sealing member...

Embodiment approach 3

[0061] Next, pass Figure 7 , The third embodiment of the present invention will be described. In this embodiment, the structure of the center seal is different from the above-mentioned embodiment. It should be noted that the same parts as those in the above-mentioned embodiment are denoted by the same reference numerals, and repeated descriptions are omitted. In this embodiment, as Figure 7 As shown, the second lip portion 245 of the central seal 240 has a first extension portion 261 and a second extension portion 262 inclined with respect to the first extension portion 261. In addition, the first extension portion 261 is formed of soft resin, and the second extension portion 262 is formed of hard resin. In this way, the rigidity of the front end of the second lip 245 can be further improved.

Abstract

This door device for cooling storage is characterized by comprising a pair of heat insulation doors 15A, 15B that are double-door style and that enable the opening / closing of an opening 10A provided in a storage body 10 of a refrigerator 1, and center seals 40 that seal between the pair of heat insulation doors 15a, 15b, wherein: each center seal 40 includes a seal body 41 that comes into contact with another center seal 40, a fin part 42 that extends from the seal body 41 to the open-close axis side of the relevant heat insulation door 15A, 15B and partitions the inside and outside of the refrigerator, a support part 43 that extends from the seal body 41 toward the inside of the refrigerator, and a second lip part 45 that extends from the tip of the support part 43 to the open-close axis side and covers the fin part 42 from inside of the refrigerator; the second lip part 45 is formed such that the tip is spaced apart, toward the inside of the refrigerator, from the fin part 42 and the relevant heat insulation door 15A, 15B; and a tip part 45A of the second lip part 45 being a highly rigid structure compared to a base part 45B of the second lip part 45.

Description

Technical field [0001] The invention relates to a door device for a cooling storage warehouse. Background technique [0002] Conventionally, there has been known a door device for a cooling storage room, which is provided with a pair of left and right side-opening heat insulation panels provided on the main body of the storage room and a central seal for sealing the space between the two heat insulation panels (for example, refer to the patent Literature 1). The central seal described in Patent Document 1 has a sealing body and a secondary lip protruding from the sealing body to the opening and closing shaft side of the thermal insulation plate (hereinafter referred to as "fin section"). The outer surface of the fin section and the thermal insulation plate The packing is connected to separate the inside and outside of the warehouse.
