Below with reference to Fig. 1 refrigerator according to the embodiment of the invention is described.
According to the refrigerator of the embodiment of the invention, comprise casing 100 and door body 200.
Particularly, be limited with chamber between refrigeration in the casing 100.Door body 200 is connected on the casing 100 pivotly to be used for opening and closing chamber between refrigeration.Be formed with the mounting groove 211 that cross section is Ω shape on the door courage 210 of door body 200, door seal 300 is buckled in the mounting groove 211 by installation portion 310, particularly, the inwall phase buckle of the hook part 311 of the installation portion 310 of door seal 300 and mounting groove 211, therefore when door body 200 is closed between refrigeration the chamber, form sealing between door body 200 and casing 100, cold air indoor between preventing from freezing is from indoor leakage between refrigeration, and outside air enters chamber between refrigeration.
Embodiment of the invention refrigerator, make the installation portion 310 of door seal 300 have enough rigidity and intensity by door seal 300 structural improvement, make the buckle power of hook part 311 be enough to competent large scale of construction refrigerator doors to the requirement of door seal 300 buckle power, for example the door body of the door body of side by side combination refrigerator or larger-size simple gate refrigerator.
The door of refrigerator that specifically describes according to the embodiment of the invention below with reference to Fig. 1 and Fig. 2 seals 300.
Draw together installation portion 310 and thermal insulation air bag 320 according to the door of refrigerator package of the embodiment of the invention.
Particularly, the inside of installation portion 310 is hollow structure and links to each other with thermal insulation air bag 320.Also can be connected with for the installing frame 331 that magnetic stripe 330 is installed at the rear portion of thermal insulation air bag 320.When door body 200 was closed, the heat conduction indoor cold air and outdoor space occured between can preventing from freezing in thermal insulation air bag 320, and magnetic stripe 330 can be pull-in on the central sill of refrigerator, to guarantee the sealing of door seal 300.Simultaneously, the adhesive of magnetic stripe 330 is had higher requirement for the buckle power of door seal 300.
Installation portion 310 comprises connecting portion 312 that an end is connected with thermal insulation air bag 320 hook part 311 that links to each other with the other end with connecting portion 312.Hook part 311 comprises the opposing snap fit 3111 that arranges of a pair of center line along installation portion 310 (passing the dotted line at installation portion center among Fig. 2 along fore-and-aft direction) mirror image, being a pair of snap fit 3111 is symmetrical arranged and snap fit 3111 outwards (outside being, otherwise then being interior away from the direction at installation portion center) along center line.Snap fit 3111 extension that recedes makes substantially triangularities of hook part 311 like this, is convenient to insert mounting groove 211 and is buckled in the mounting groove 211.
As shown in Figure 2, the back edge 3112 of snap fit 3111 with the front along 3113 each other in angle a, setting can guarantee that snap fit 3111 integral body have certain thickness (the particularly front portion 3114 of snap fit 3111) like this, improved the bulk strength of hook part 311, made door seal 300 be installed to mounting groove 211 and can not come off after interior.In addition, greater than zero, in other words, back edge 3112 does not intersect along 3113 with the front, can not form a tip to the front along 3113 minimum range for back edge 3112, has certain thickness and colludes end 3115 but form.Setting can guarantee that the concrete enough intensity in end 3115 of colluding of snap fit is buckled in buckle power in the mounting groove 211 with lifting like this.
Thus, door seal 300 according to the embodiment of the invention, said structure by hook part 311 improves, not only can improve the bulk strength of hook part 311, but also the local strength that can improve the chimoto of snap fit 3111, and then the buckle power that has improved hook part 311 is to adapt to large scale of construction refrigerator doors to the requirement of door seal 300 buckle power.In addition, the door seal 300 of the embodiment of the invention is simple in structure, is convenient to processing and manufacturing.
According to one embodiment of present invention, the back edge 3112 of snap fit 3111 and front are spent greater than 20 along 3113 angle a, guarantee that further the front portion 3114 of snap fit 3111 has enough thickness.
Minimum range along 3113 is 0.5-1mm to back edge 3112 to the front, can guarantee further that like this colluding end 3115 has enough thickness.
In addition, as shown in Figure 1, the lateral wall 3121 of connecting portion 312 and thermal insulation air bag 320 junctions is 1.3-1.7mm with the parallel distance H of the outer end of the back edge 3112 of snap fit 3111, and distance H also can be understood as the substantially horizontal range of protruding connecting portion 312 of snap fit 3111.Arrange like this can guarantee that snap fit 3111 has under the prerequisite of enough buckle power not can be because of long and cause remitted its fury.
As shown in Figure 2, according to another embodiment of the invention, the madial wall 3122 of connecting portion 312 and lateral wall 3121 parallel to each other and maintenance certain distances, namely the wall of connecting portion has certain thickness with support card hook part 311.
Preferably, the wall thickness of connecting portion 312 is 0.9-1.1mm.
The bottom of connecting portion 312 can be to interior to bending, to increase the thickness that colludes end 3115 of snap fit 3111.
Other formations of refrigerator of the present invention can be well known by persons skilled in the art, do not repeat them here.
In the description of this specification, the description of reference term " embodiment ", " some embodiment ", " example ", " concrete example " or " some examples " etc. means to be contained at least one embodiment of the present invention or the example in conjunction with specific features, structure, material or the characteristics of this embodiment or example description.In this manual, the schematic statement of above-mentioned term not necessarily referred to identical embodiment or example.And the specific features of description, structure, material or characteristics can be with suitable mode combinations in any one or more embodiment or example.
Although illustrated and described embodiments of the invention, those having ordinary skill in the art will appreciate that: can carry out multiple variation, modification, replacement and modification to these embodiment in the situation that does not break away from principle of the present invention and aim, scope of the present invention is limited by claim and equivalent thereof.
