Abstract
The present invention provides an air hole structure of a refrigerator door, which relates to a refrigerator door. Heat insulating foamed liquid is filled in the refrigerator door, concave hinge holes are arranged on side surfaces, and air holes are arranged in the hinge holes. Gas generated in the solidification process of the foamed liquid can be fluently discharged through the air holes. As the air holes are not exposed, little foamed liquid which flows out through the air holes can not affect the appearance of the refrigerator door.
Description
Technical field
The present invention relates to a kind of air hole structure of refrigerator doors, relate to particularly that a kind of pore does not expose and can effectively prevent the air hole structure of expanding foam solution outflow.
Background technology
Refrigerator is to utilize freeze cycle to produce cold air and the refrigerating machine of preserving food, and its storage space keeps low-temperature condition, so that food wherein keeps is fresh.For this reason, utilize heat-barrier material to prevent that storage space and outside from carrying out heat exchange usually.Above-mentioned heat-barrier material not only is filled in the refrigerator body that forms storage space, is filled with heat-barrier material equally in the refrigerator door that opens and closes storage space, flows out to prevent the cold air in the storage space.
Fig. 1 is the medial elevational view of current refrigerator door.As shown in Figure 1, the outside of refrigerator doors 2 is shell body 4 and is made by steel plate, avoids outside impact to protect inner parts; The inboard of refrigerator doors 2 is provided with door gasket 6, is generally made by ABS resin, is formed with the space that can put into food in it; The upside of refrigerator doors 2 is provided with to the doorstep body 8 and links to each other with door gasket 6 with shell body 4, above formation refrigerator doors 2; Equally, the downside of refrigerator doors 2 is provided with Xiamen body 10 and links to each other with door gasket 6 with shell body 4, below formation refrigerator doors 2.
Be filled with heat-barrier material in above-mentioned shell body 4, door gasket 6, call body 8 and the Xiamen body 10 formed confined spaces, expanding foam solutions such as general employing polyurethane foam, this expanding foam solution can carry out the heat cure reaction and form heat reactive resin under the effect of special catalyst.In the solidification process of above-mentioned expanding foam solution, gases such as freon are by free, and expanding foam solution then becomes the porous, expanded medium with micron order micropore.The surface of door gasket 6 is formed with a plurality of pores 5, and the gas that is produced in above-mentioned expanding foam solution solidification process is promptly discharged by pore 5.
In above-mentioned air hole structure of door for refrigerator, because pore 5 exposes, so in the expanding foam solution solidification process,, thereby influence the outward appearance of refrigerator doors along with the discharge of gas will have small amount of foaming liquid by pore 5 outflows and expose; In order to remove the expanding foam solution that exposes, must increase flow chart again, thereby cause the reduction of production efficiency.
Summary of the invention
Purpose of the present invention promptly is to provide a kind of to be had the refrigerator doors of hidden pore and makes by the expanding foam solution of pore outflow still less, removes the flow chart that exposes expanding foam solution thereby needn't increase.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of air hole structure of door for refrigerator, the inside of refrigerator doors is filled with heat insulation expanding foam solution; A side that it is characterized in that described refrigerator doors is formed with recessed pan, is provided with the pore that is used for discharging the gas that the expanding foam solution solidification process produces in this pan.
Aforesaid air hole structure of door for refrigerator, wherein pore is the wedged hole that is become by excision pan base dihedral.
Aforesaid air hole structure of door for refrigerator, wherein pore is narrowed down to export department gradually by inlet portion.
Above-mentioned pore, can not impact the outward appearance of refrigerator doors even therefore have a spot of expanding foam solution to flow out by pore owing to do not expose yet; Suitably select the position of pore and the discharge that shape also can reduce expanding foam solution.
Be described in further detail below in conjunction with the technical characterictic of specific embodiment air hole structure of door for refrigerator of the present invention.
Description of drawings
Fig. 1 is the medial elevational view of current refrigerator door.
Fig. 2 is the enforcement illustration of refrigerator air hole structure of the present invention.
Fig. 3 is the detail drawing of B portion among Fig. 2.
Fig. 4 is an A-A cutaway view among Fig. 3.
The specific embodiment
As shown in Figure 2, the outside of refrigerator doors 22 is an external door body 24, and the inboard of refrigerator doors 22 is a door gasket 26, and the upside of refrigerator doors 22 is provided with body 28 to the doorstep and links to each other with door gasket 26 with external door body 26 and constitute the upper side of refrigerator doors 22; The left and right sides of the body 28 to the doorstep of refrigerator doors 22 forms the pan 34 with certain depth, can insert the hinge axis (not shown) that links to each other with refrigerator body in the pan 34, opens and closes refrigerator doors 22 with the turn by hinge axis.Equally, the downside of refrigerator doors 22 is provided with Xiamen body 30 and links to each other with door gasket 26 with external door body 26 and constitute the downside of refrigerator doors 22; The left and right sides of Xiamen body 30 is formed with the pan 34 ' with certain depth, and the door handle 31 that is used to open and close refrigerator doors 22 promptly is arranged between the above-mentioned pan 34 '.
As shown in Figure 3 and Figure 4, pan 34 is formed with pore 40, and this pore 40 is wedge shapes of forming by the bottom edge of excision pan 34, and its inlet is wide and outlet is narrower, and the pore that is formed at pan 34 ' is identical therewith.
In the present embodiment, pore 40 is formed in the pan 34,34 ', but is not limited to this, gets final product so long as be formed in the pan of refrigerator doors side and do not expose.
When assembling above-mentioned refrigerator doors 22, be that will call body 28 and Xiamen body 30 is arranged on the external door body 24, again door gasket 26 is attached on call body 28 and the Xiamen body 30 after injecting expanding foam solution, to form the outward appearance of refrigerator doors 22, in the expanding foam solution solidification process, the gas that is produced is discharged by pan 34,34 ' interior pore 40, also has small amount of foaming liquid to flow out by pore 40 simultaneously.
Owing to pore 40 is wedge shapes of forming of corner portion by excision pan 34, its inlet portion broad and export department is narrower, so gas be easy to by, and expanding foam solution is difficult to flow out.In addition, the inclined-plane area of pore 40 is bigger, and flow resistance is bigger, therefore has only the expanding foam solution of minute quantity to flow out by pore 40.Obviously, the central angle of pore 40 is big more, and the inclined-plane area of pore is big more, and the expanding foam solution that flows out by pore is then few more.
