See the specific embodiment that Fig. 4, Fig. 4 are embodiment of the present invention door of refrigerator envelope, the door of refrigerator package of the present embodiment is drawn together: magnetic stripe capsule 1, and described magnetic stripe capsule 1 is for placing magnetic stripe; Installation foot 2, described installation foot 2 is for being installed to refrigerator door liner by described door seal; Air bag 3, described air bag 3 is connected between described magnetic stripe capsule 1 and described installation foot 2, described air bag 3 comprises the longitudinal wall 31 relative with refrigerator door liner and transverse wall 32, horizontal rib 41 and lengthways of rod 42 is provided with in the air cavity 5 of described air bag, described horizontal rib 41 one end is connected with the outer wall of described magnetic stripe capsule 1, the other end is connected with described longitudinal wall 31, and the first end of described lengthways of rod 42 is connected with described horizontal rib 41, and the second end of described lengthways of rod 42 is connected with described transverse wall 32.
A kind of door of refrigerator envelope that the embodiment of the present invention provides, owing to being provided with horizontal rib 41 and lengthways of rod 42 in the air cavity 5 of air bag 3, therefore can being formed air bag 3 inside and effectively support.Particularly, because horizontal rib 41 one end is connected with the outer wall of magnetic stripe capsule 1, the other end is connected with longitudinal wall 31, and longitudinal wall 31 is oppositely arranged with refrigerator door liner, therefore, when magnetic stripe capsule 1 is pull-in on refrigerator body side plate, and continue in the process of closing refrigerator door, refrigerator door liner can be fitted with longitudinal wall 31, and apply the thrust in a direction of closing the door to longitudinal wall 31, thrust can be passed to magnetic stripe capsule 1 by horizontal rib 41 by longitudinal wall 31, thus provide a more firm cross-brace power to magnetic stripe capsule 1, prevent air bag 3 from occurring laterally to cave in the process promoting the slip of magnetic stripe capsule 1, simultaneously owing to being provided with lengthways of rod 42 in the air cavity 5 of air bag 3, the first end of lengthways of rod 42 is connected with horizontal rib 41, second end of lengthways of rod 42 is connected with transverse wall 32, and transverse wall 32 and refrigerator door liner are oppositely arranged, therefore, when magnetic stripe capsule 1 is pull-in on side plate, and continue in the process of closing refrigerator door, refrigerator door liner applies the thrust in a direction of closing the door can to transverse wall 32, this thrust is passed to magnetic stripe capsule 1 or horizontal rib 41 by transverse wall 32, thus provide a more firm longitudinal holding power to magnetic stripe capsule 1 or horizontal rib 41, air bag 3 is prevented to occur longitudinally to cave in the process promoting the slip of magnetic stripe capsule 1.Thus, by horizontal rib 41 and lengthways of rod 42 acting in conjunction, increase the inner support power of door seal air bag 3, prevent be squeezed evagination or cave in of air bag 3 from caving in, thus increase door seal scrap (bridge) distance, reduce door seal distortion, crimping probability.
In the above-described embodiments, the first end of lengthways of rod 42, except can being connected with horizontal rib 41, can also be connected with the outer wall of magnetic stripe capsule 1.When the first end of lengthways of rod 42 is connected with horizontal rib 41, be pull-in on side plate at magnetic stripe capsule 1, and continue in the process of closing refrigerator door, because horizontal rib 41 one end is connected with the outer wall of magnetic stripe capsule 1, therefore lengthways of rod 42 can transmit a longitudinal holding power to magnetic stripe capsule 1 by horizontal rib 41, thus with the acting in conjunction of horizontal rib 41, the supporting role power of augmented airbag 3 pairs of magnetic stripes, and then increase crack between a door and its frame scrap (bridge) distance, in addition, lengthways of rod 42 can also play fixed support effect to horizontal rib 41, prevent horizontal rib 41 because of stressed excessive and produce flexural deformation, ensure that effective support of horizontal rib 42 pairs of air bags 3, because on horizontal rib 41, medium position is the most yielding, therefore can further preferably the first end of lengthways of rod 42 be connected to the medium position of horizontal rib 41, when lengthways of rod 42 is connected with the outer wall of magnetic stripe capsule 1, lengthways of rod 42 provides a longitudinal holding power directly to magnetic stripe capsule 1, support force is more firm, but now horizontal rib 41 due to without supporting stressed excessive time easily produce flexural deformation, thus have impact on the cross-brace effect of horizontal rib 41 pairs of magnetic stripe capsules 1.
Above-mentioned door seal is fixed on the door courage of refrigerator door, when refrigerator door is closed completely, assembly structure between door seal, refrigerator door liner, refrigerator courage, side plate as shown in Figure 5, see Fig. 5, installation foot 2 cooperation is inserted in the mounting groove 61 on refrigerator door liner 6, to realize door seal fixing on refrigerator door liner 6, refrigerator courage 7 is provided with side plate 8, magnetic stripe 11 can by magnetic attraction on side plate 8, door seal is made to seal gap between refrigerator courage 7 and refrigerator door liner 6, intercept the exchange heat that refrigerator is inside and outside, reduce the energy consumption of refrigerator.
It should be noted that, for convenience of description, when door seal is installed on refrigerator door liner, definition door seal is upside near the side of refrigerator courage, relative with upside, and is downside near the side of refrigerator door liner.
In order to the support force of augmented airbag 3, increase the scrap (bridge) distance of door seal, reduce door seal distortion, crimping probability, as shown in Figure 4, preferred lengthways of rod 42 is arranged perpendicular to transverse wall 32 or the first end of lengthways of rod 42 is obliquely installed to the direction near magnetic stripe capsule 1 relative to the second end, lengthways of rod 42 is α with the angle of transverse wall 32, α≤90 °, when with in the process of direction of arrow closing refrigerator door in such as Fig. 6, lengthways of rod 42 can provide an oblique upper left holding power F1, and preferably the direction of F1 is consistent with refrigerator door closing direction, now F1 can provide a component on the direction perpendicular to magnetic stripe capsule 1, this component plays certain supporting role to door seal, door seal in refrigerator door closing process is prevented to be out of shape because being squeezed or air bag 3 caves in and caves in.Preferably lengthways of rod 42 is β with the angle of horizontal rib 41 again, 45 °≤β≤90 °, when with in the process of direction of arrow closing refrigerator door in such as Fig. 6, horizontal rib 41 can provide a support force F2 to magnetic stripe capsule 1, and preferably the direction of F2 is consistent with refrigerator door closing direction, make the direction of support force F2 for oblique upper left side as shown in Figure 6, continue mobile until refrigerator door is completely closed to provide a component on the direction being parallel to magnetic stripe capsule 1 on side plate 8 to promote magnetic stripe 11, solve door seal scrap (bridge) apart from problem less than normal, produce a component in the direction perpendicular to magnetic stripe capsule 1 simultaneously, to strengthen air bag 3 inner support power.
Wherein, lengthways of rod 42 can be linear pattern, also can overall curved type.When adopting above-mentioned first scheme, namely lengthways of rod 42 is overall curved, in the process of closing refrigerator door body, the transverse wall 32 of refrigerator door liner 6 extruding gasbag 3, an active force is applied near one end of transverse wall 32 to lengthways of rod 42, under this active force, lengthways of rod 42 easily occurs bending and deformation, make lengthways of rod 42 to the underbraced of horizontal rib 41 or magnetic stripe capsule 1, and then cause the underbraced of lengthways of rod 42 pairs of magnetic stripes 11, easily make be squeezed evagination or cave in of air bag 3 cave in time serious, thus reduce door seal scrap (bridge) distance.Therefore, in order to avoid the problems referred to above, preferred lengthways of rod 42 is linear pattern, and the direction of active force is identical with the rectilinear direction at lengthways of rod 42 place, effectively can support magnetic stripe 11 and move forward on side plate 8, increase door seal scrap (bridge) distance.
For No. 1 refrigerator, No. 2 refrigerators and No. 3 refrigerators, adopt the gap between the door seal sealing refrigerator door of prior art (as shown in Figure 1) and the embodiment of the present invention (as Fig. 4) and refrigerator body respectively, then respectively measure refrigerator visit top, top, middle part, bottom, the scrap (bridge) of the top of Xiamen, middle part, bottom is apart from value, obtain two groups of reduced values, and by two groups of reduced value records in Table 1.Measurement data as can be seen from table 1: at theoretical scrap (bridge) apart under identical condition, the i.e. size of magnetic stripe capsule 1 and air bag 3 and the equal no change of relative position, the door seal scrap (bridge) of the embodiment of the present invention is obviously greater than prior art door seal scrap (bridge) apart from measured value apart from measured value.This illustrates in practical set and use procedure, and horizontal rib 41 and lengthways of rod 42 effectively can strengthen air bag 3 inner support power, increases door seal scrap (bridge) distance, reduces door seal crimping probability.And prior art door seal air bag 03 inner support is not enough, in the process of closing refrigerator door body, air bag 03 is difficult to effectively to promote magnetic stripe 011 and moves forward on side plate 08, and air bag 03 easily produces evagination after being squeezed, the problem such as to cave in of caving in, thus cause door seal scrap (bridge) apart from the low side, easily produce the problems such as door seal distortion, crimping time serious, affect the sealing thermal insulation effect of door seal.
Table 1
It should be noted that, in embodiments of the present invention, be only described for above-mentioned table 1, above-mentioned table 1 does not form restriction to the embodiment of the present invention.
Wherein, one end that horizontal rib 41 is connected with magnetic stripe capsule 1 can be bending, as shown in Figure 4, the sweep of horizontal rib 41 to be connected with magnetic stripe capsule 1 by strong point P2 and to play supporting role upwards to magnetic stripe capsule 1, newly-increased strong point P2 and original strong point P1 acts synergistically, enhance air bag 3 inside to the support strength of magnetic stripe capsule 1, prevent from door closing procedure, occurring that magnetic stripe capsule 1 rotates around the single strong point and produces assembly problem, if door seal scrap (bridge) is apart from less than normal, door seal crimping or produce gap between door seal and side plate 8, and, because in actual production manufacture process, the control of chamber door spacing is unsatisfactory, refrigerator body, refrigerator doors etc. and door seal have the parts of assembly relation to be slightly out of shape the deviation that all can cause chamber door spacing and theoretical value, or even the chamber door spacing of same refrigerator diverse location all can be different, therefore, bending structural design can give air bag 3 certain elasticity, make air bag 3 can be adapted to the chamber door spacing of deviation fluctuation within the specific limits in actual production process by the dilatation of warp architecture, thus efficiently solve the problems such as door seal crimping or gap.
Alternatively, one end that horizontal rib 41 is connected with magnetic stripe capsule 1 can also be linearity, as shown in Figure 7, now the right side wall of horizontal rib 41 and magnetic stripe capsule 1 or summit, the lower right corner are connected, promote magnetic stripe 11 by the thrust F2 of horizontal rib 41 at the component being parallel to magnetic stripe capsule 1 direction to move on side plate 8, at strong point P2 place, supporting role is upwards played to magnetic stripe capsule 1 at the component perpendicular to magnetic stripe capsule 1 direction by F2, and act synergistically with original strong point P1, when preventing closing refrigerator door body, magnetic stripe capsule 1 rotates around the single strong point and produces assembly problem.This possibility is applicable to the door seal cross-sectional shape that height is lower, air bag 3 indoor design space is less of air bag 3, extrudes, welding usability to take into account door seal, avoids door seal to be adhered.
Particularly, as shown in Figure 4, the air cavity 5 of air bag 3 is divided into the first air chamber 51, second air chamber 52 and the 3rd air chamber 53 by horizontal rib 41 and lengthways of rod 42.First air chamber 51 is concordant with magnetic stripe capsule 1 and be positioned at the top of horizontal rib 41, be pull-in on side plate at magnetic stripe capsule 1, and continue in the process of closing refrigerator door, refrigerator door liner can extrude the first air chamber 51, the first air chamber 51 is made to provide a support force to magnetic stripe capsule 1, this support force can promote magnetic stripe 11 and move forward on side plate 8, thus increases the scrap (bridge) distance of door seal; Second air chamber 52 is positioned at the below of the first air chamber 51, be pull-in on side plate at magnetic stripe capsule 1, and continue in the process of closing refrigerator door, refrigerator door liner can extrude the second air chamber 52, the second air chamber 52 is made to provide a support force to lengthways of rod 42, improve the supporting role of lengthways of rod 42 to horizontal rib 41 or magnetic stripe capsule 1,3rd air chamber 53 is concordant with the second air chamber 52, lengthways of rod 42 is between the second air chamber 52 and the 3rd air chamber 53, a part for 3rd air chamber 53 is positioned at the below of magnetic stripe capsule 1, and another part is positioned at the below of the first air chamber 51.Because the coefficient of heat conduction (about 0.0223W/m.K) of air is lower, therefore door seal normally utilizes the air of inside air bag to suppress or reduces the inside and outside exchange heat of refrigerator, therefore can further by inside air bag being divided into multiple air chamber to strengthen the sealing heat-proof quality of air bag, multiple air chamber is separate, gas not convection current between adjacent 2 air chambers, significantly can reduce exchange heat between the two, and more by the air cavity quantity separated, the sealing thermal insulation of air bag is better.Compared with prior art embodiment as shown in Figure 1, the door of refrigerator of the employing embodiment of the present invention is sealed the gap between refrigerator door and casing, the air cavity of air bag is divided into three air chambers independent of each other by horizontal rib and lengthways of rod, compared to two air chambers of prior art, the quantity of air chamber increases, greatly reduce heat exchange amplitude, effectively inhibit the exchange heat that refrigerator is inside and outside.Certainly, those skilled in the art also can increase the segmentation of more air chamber again.
Wherein, prior art embodiment as shown in Figure 3, when door seal is applied in refrigerator as shown in Figure 3, if chamber door spacing is lower than theoretical value, now because balloonet 09 exceeds magnetic stripe capsule 01, once magnetic stripe is pull-in on box side, balloonet 09 will produce mutual squeezing action with side plate 08, thus the frictional force increased between the two, be unfavorable for magnetic stripe capsule 01 slippage forward on side plate 08 at closing time, thus reduce door seal scrap (bridge) distance, cause door seal crimping, and the elastic potential energy of savings also can bring other assembly technology problems, as the bounce-back of door body, manufacture, cost increase etc. is reprocessed in maintenance, therefore this scheme door seal is not suitable for the product of chamber door spacing lower than theoretical value, thus reduce the universality of door seal.Therefore, the harmful effect that the upper surface of balloonet 09 produces higher than magnetic stripe capsule 01 upper surface in prior art as shown in Figure 3, preferably the upper surface of the first air chamber 51 is concordant with the upper surface of magnetic stripe capsule 1, even if chamber door spacing is lower than theoretical value thus, magnetic stripe 11 adhesive in the process of slippage forward on box side 8, air bag 3 can not produce mutual extruding with side plate 8, avoid problems such as occurring air bag 3 and side plate frictional force increase, refrigerator door bounce-back, thus increase the scrap (bridge) distance of door seal, improve the universality of door seal.
Because distortion to a certain degree easily appears in refrigerator body, refrigerator door in manufacturing process; for making up this deflection; certain fit clearance can be left usually in door seal and refrigerator courage 7, refrigerator door liner 6 surrounding fitting part, the cold air of refrigerator inside can directly by this gap to outward leakage.Therefore, in order to avoid the problems referred to above, preferably the first wing limit 33 is set at the outer surface of the junction of longitudinal wall 31 and transverse wall 32, can in baffle box cold air from refrigerator door liner 6 with door seal fit clearance to outward leakage, and the first wing limit 33 can form two equivalent air bags with refrigerator door liner 6 interference fit, can reduce the heat exchanger effectiveness of refrigerator door liner 6 and door seal cooperation place further.This structure is simple, and cost of manufacture is low.
In like manner, as shown in Figure 5, preferably above the first side of air chamber 51 away from magnetic stripe capsule 1, connect auxiliary balloon 9, its shape and refrigerator courage 7, refrigerator door liner 6 cooperation place structure match, can fit clearance effectively between shutoff refrigerator courage 7 and refrigerator door liner 6.Structure is simple, and can realize the effective sealing of fit clearance.
Further, in order to strengthen the sealing heat-proof quality of auxiliary balloon 9, multiple air chamber independent of each other can be comprised in the air cavity of auxiliary balloon 9, such as, can comprise two air chambers independent of each other as shown in Figure 5, thus reduce the energy exchange efficiency of cold air and extraneous hot-air in refrigerator.
For ease of the assembling of installation foot 2 in mounting groove 61 in actual production process, simultaneously for avoiding foozle to cause installing difficulty, usually the degree of depth of mounting groove 61 being arranged larger than the height of installation foot 2, operating to facilitate installation.As shown in Figure 5, the degree of depth of the aspect ratio mounting groove 61 of door seal installation foot 2 is little, there is gap between the bottom of the rear installation foot 2 of assembling and the bottom of mounting groove 61, and from then on the cold air in refrigerator can be revealed by gap location, increases the energy consumption of refrigerator.For avoiding the problems referred to above, the bottom of installation foot 2 can arrange forniciform second wing limit 34, when installation foot 2 is inserted in mounting groove 61, fit in the bottom on the second wing limit 34 and the bottom of mounting groove 61, the end on the second wing limit 34 tilts, the gap of differing heights can be adapted to, there is good deformability and adaptability, and with can insert smoothly during mounting groove 61 interference fit and fit with the bottom of mounting groove 61, gap can not be produced because of bending distortion, can effectively prevent cold air in case bottom installation foot 2 and bottom mounting groove 61 between gap to outward leakage, simultaneously, mounting groove 61 bottom gap is divided into two and forms two the equivalent air bags in left and right by the second wing limit 34, reduce outside air heat convection efficiency, improve the sealing heat-proof quality of door seal.This structure is simple, low cost of manufacture.
