Abstract
The utility model discloses a wind shielding strip for a refrigerator. The wind shielding strip is characterized by comprising a U-shaped clamping groove and a streamline sealing strip(s), wherein the streamline sealing strip is arranged at any end of the opening of the U-shaped clamping groove, or the streamline sealing strips are arranged abreast on the outer side of the bottom of the U-shaped clamping groove; the U-shaped clamping groove is matched with a fastener of the middle beam of the refrigerator body to form a fixed structure; the streamline sealing strip(s) is/are matched with a refrigerator door boss to form a sealing structure. According to the wind shielding strip for the refrigerator, the sealing performance and the refrigeration effect of a refrigerator door can be effectively ensured, energy and electricity are saved, and the service life of the refrigerator is prolonged.
Description
Technical field
The utility model relates to a kind of refrigerator weather strip.
Background technology
Upgrading along with the technology of household electrical appliances, energy-conservation be the key issue that refrigerator is paid close attention to always, and door seal cold draining accounts for very most of that cold scatters and disappears, weather strip is larger as the lost secondary safeguard procedures effect of refrigerator cold, but existing weather strip, due to the design defect on structure and material, causes long-time use to be agingly out of shape, in structure, no longer keep well sealing with door body boss position, thereby cause refrigerator cold draining power consumption power consumption, have a strong impact on refrigerator service life.
And in currently available technology, easily hardening at low temperatures of soft-hard coextrusion PVC weather strip used always, thereby also affected the sealing of door of refrigerator, and the plasticizer DOP that soft materials part is added easily separates out a corrosion door courage liner material, cause the crackings such as a courage inner bag or the softening groove that forms.
Summary of the invention
For overcoming the defect of prior art, the object of the present invention is to provide a kind of refrigerator weather strip, can effectively guarantee sealing and the refrigeration of door of refrigerator, energy saving, extends refrigerator service life.
The utility model technical solution problem adopts following technical scheme:
A kind of refrigerator of the utility model by the design feature of weather strip is, one " U " type draw-in groove and streamlined sealing strip are set, and the structure of described " U " type draw-in groove and streamlined sealing strip is set to:
Described streamlined sealing strip is arranged on arbitrary end of described " U " type draw-in groove opening, or is set up in parallel the bottom outside at described " U " type draw-in groove;
The formation fixed structure that is clasped of described " U " type draw-in groove and refrigerator body central sill, described streamlined sealing strip coordinates formation hermetically-sealed construction with chamber door boss.
The utility model refrigerator is also by the design feature of weather strip:
Described " U " type draw-in groove adopts polypropylene PP plastics, and described streamlined sealing strip adopts thermoplastic elastomer (TPE) TPE material.
Described thermoplastic elastomer (TPE) TPE material is for making the SEBS hydrogenated styrene block copolymers of soft chain segment with BR hydrogenation.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model forms stable fixed structure by being clasped of " U " type draw-in groove and refrigerator central sill, add the compactness that streamlined sealing strip coordinates with chamber door boss, thereby guaranteed the sealing effectiveness of weather strip, efficiently solved the problem of refrigerator cold draining.
2, the utility model " U " type draw-in groove position adopts the PP/TPE co-extrusion weather strip that PP material, streamlined sealing strip adopt TPE hydrogenated styrene block copolymers material to be co-extruded, the weather strip operation of this kind of material moulding is simple, excellent performance, asepsis environment-protecting, play and well prevent the lost effect of cold, the PVC of cost and soft-hard coextrusion is similar.
3, the TPE hydrogenated styrene block copolymers material that the streamlined sealing strip of the utility model adopts, this kind of material is difficult for bending fracture, tracing ability is better, under cryogenic conditions, still can keep good elasticity, assurance closely cooperates with door body boss position, and TPE compares with PVC, more high temperature resistant and low temperature, there is better elasticity, do not need to add plasticizer, environment-protecting asepsis, the problem of the not environmental protection of PVC weather strip of soft-hard coextrusion before having avoided.

The specific embodiment
In the present embodiment, a kind of refrigerator weather strip is, one " U " type draw-in groove 1 and streamlined sealing strip 2 are set, and the structure of " U " type draw-in groove 1 and streamlined sealing strip 2 is set to:
As shown in Figure 1, streamlined sealing strip 2 is arranged on arbitrary end of " U " type draw-in groove 1 opening, form one-level safeguard structure, or as shown in Figure 2, two streamlined sealing strips 2 is set up in parallel the bottom outside at " U " type draw-in groove 1, forms secondary safeguard structure;
As shown in Figure 3 and Figure 4, the formation fixed structure that is clasped of " U " type draw-in groove 1 and refrigerator body central sill 3, streamlined sealing strip 2 coordinates formation hermetically-sealed construction with chamber door boss 4.In door of refrigerator closing process, chamber door boss 4 forces streamlined sealing strip 2 be out of shape and keep synchronizeing and following with it, and streamlined sealing strip 2 is that high resilience makes to keep closely cooperating with chamber door boss 4 to prevent that cold scatters and disappears, and strengthens cold draining sealing.And secondary safeguard structure is to make inside and chamber door boss 4 engagement edges tightr by outward flange elastic pressure, duplicate protection, further reinforced door body and box body tightness, save the energy, thereby adapt to different types of refrigerator body center sill structure.
Refrigerator weather strip in the present embodiment is formed by hard material PP and soft material TPE composite co-extruding, " U " type draw-in groove 1 adopts the good polypropylene PP plastics of lower temperature resistance of modification, streamlined sealing strip 2 adopts thermoplastic elastomer (TPE) TPE material, a kind of novel elastomer material that SEBS materials processing that thermoplastic elastomer (TPE) TPE material is high-quality becomes, principal component SEBS(Styrene-ethylene-butylene-styrene block copolymer) formal name used at school is hydrogenated styrene block copolymers.With BR hydrogenation, make the SEBS hydrogenated styrene block copolymers of soft chain segment, under low temperature, also can keep better soft elasticity.
The utility model refrigerator can be widely used in the sealing protection between refrigerator industry Men Tiyu casing with co-extrusion weather strip, as the auxiliary cold draining parts that prevent of seal strip for refrigerator door, reduces energy consumption of refrigerator, saves the energy.Compare soft-hard coextrusion PVC weather strip superior performance, safety and environmental protection.
