The specific embodiment
It will be understood by those skilled in the art that following to the specific descriptions of embodiments of the invention just to fully openly the present invention, and should not be construed as, limit the scope of the invention; Scope of the present invention is defined by the claims.
In this article, term " first ", " second " are only for convenience, do not limit the scope of protection of present invention.
Refrigerator of the present invention comprises casing and refrigerator doors, and described refrigerator doors comprises refrigerator doors sealing device, and described refrigerator doors sealing device comprises: annular sealing strip, and it is made by elasticity gas impermeable material, and has at least one first gas chamber; Fill exhaust component, be communicated with described at least one first gas chamber's gas of described annular sealing strip, be used to described at least one inflation of the first gas chamber and exhaust; And control assembly, be operatively connected with the described exhaust component that fills, for filling exhaust component described in controlling, be described at least one inflation of first gas chamber or exhaust.Described refrigerator doors can engage with described box sealing by described annular sealing strip.By described annular sealing strip, can realize the refrigerator doors of refrigerator and the abundant sealing of casing, and stop heat from the gap between the two, to enter storeroom and stop cold air to spill described storeroom from described gap, can greatly improve the heat-proof quality of refrigerator.
Fig. 2 shows the schematic cross sectional views of the refrigerator of one embodiment of the present of invention, and wherein refrigerator doors sealing device is in gas-flow closure state; Fig. 3 shows the front view of refrigerator doors sealing device of the refrigerator of Fig. 2; Fig. 4 shows the schematic cross sectional views of the refrigerator of Fig. 2, and wherein refrigerator doors sealing device is in exhaust contraction state; Fig. 5 shows the front view of a part of refrigerator doors of the refrigerator of Fig. 4.As shown in the figure, refrigerator 10 comprises casing 11 and refrigerator doors 12, is formed for the storeroom 24 of storage food, for example refrigerating chamber, refrigerating chamber or temperature-changing chamber between the two.Refrigerator doors 12 comprises refrigerator doors sealing device 13.Refrigerator doors 12 can also comprise door seal 25, and its structure and material is known in the art.Refrigerator doors sealing device 13 comprises annular sealing strip 14, fills exhaust component 15, control assembly 16.Annular sealing strip 14 comprise one with first gas chamber 17 of filling exhaust component 15 gases and being communicated with.Annular sealing strip 14 is removably fixed on the inner surface of refrigerator doors 12, fills exhaust component 15 and is located in refrigerator doors 12, and control assembly 16 is positioned at and fills exhaust component 15 and be located at refrigerator doors 12, can be by user at refrigerator external control.In use, filling exhaust component 15 can be 17 inflation or the exhausts of the first gas chamber.Control assembly 16 with fill exhaust component 15 and be operatively connected, for controlling the first gas chamber 17 inflation or exhausts that to fill exhaust component 15 be annular sealing strip 14.
In illustrated embodiment, filling exhaust component 15 can be ripple box.Thereby it is 17 inflations of the first gas chamber that ripple box shrinks under being subject to from the pressure of control assembly 16, sees Fig. 2.Fig. 2 shows refrigerator 10 in the duty of closing the door.Particularly, in use, user pushes hard the elastic force of control assembly 16 opposing ripple boxes and control assembly 16 is locked in to aerating position, make ripple box pressurized, the gas storing in it is extruded in the first gas chamber 17 of annular sealing strip 14, and annular sealing strip 14 is expanded, and fits tightly the inner surface of casing 11, gap between casing 11 and refrigerator doors is stopped up, prevented that cold air (cold) from leaking and hot gas (heat) enters.For control assembly 16 is locked in to aerating position, refrigerator doors 12 can be provided with limiting component, and for example projection 23.In addition, thereby ripple box can also rely on spring automatically to expand air-breathing, be 17 exhausts of the first gas chamber, see Fig. 4.Fig. 4 shows refrigerator open SBR.Control assembly 16 can comprise having the applicable annular section 19 of holding and have and the contact portion 20 of filling exhaust component 15 and contacting.Owing to having described annular section, control assembly 16 also can be used as the handle of refrigerator doors.Particularly, user is along the annular section 19 (as shown in Figure 5) of clockwise shearing control assembly 16, by it from aerating position release, be transformed into exhaust position, now ripple box, under spring force effect, expands outwardly, the gas in the first gas chamber 17 of absorption annular sealing strip 14, cause annular sealing strip 14 to shrink, depart from the inner surface of casing 11.Then can easily open the door.As shown in Figure 5, refrigerator doors 12 can also be provided with the cue mark 21 of indication control assembly 16 in aerating position, and/or is provided with indication control assembly another cue mark 22 in exhaust position.
Fig. 6 shows the cross sectional representation of a modification of annular sealing strip of the refrigerator doors sealing device of Fig. 3.As shown in Figure 6, annular sealing strip 14 can also comprise one not with second gas chamber 18 of filling exhaust component 15 and being communicated with.The second inflating cells 18 seals, and in use can be out of shape.Described in the existence of the second inflating cells 18 can reduce, fill the each aeration quantity of exhaust component and capacity, described in can reducing, fill the volume of exhaust component and realize and fill fast exhaust.The shape of cross section of annular sealing strip 14 differs and is decided to be circle as shown in the figure, can be irregularly shaped for other.The shape of cross section of the shape of cross section of the first inflating cells 17 and the second inflating cells 18 differs and is decided to be shape as shown in the figure, can be other irregular shapes.The cross-sectional area of the first inflating cells 17 can equate with the cross-sectional area of the second inflating cells 18, or is greater than the cross-sectional area of the second inflating cells 18, also can be less than the cross-sectional area of the second inflating cells 18.Should be understood that the second inflating cells 18 can omit.In addition, it should be understood that the quantity of the first inflating cells 17 and the quantity of the second inflating cells 18 can be for a plurality of.Annular sealing strip 14 can be by vinyl plastics extrusion moulding.Such annular sealing strip production cost is low, and the heat-proof quality that had of this material.For example, in the situation that annular sealing strip 14 comprises a plurality of gas chamber (the first gas chamber and the second gas chamber), can comprise that the annular sealing strip heat bonding of single gas chamber forms by a plurality of.
Although the exhaust component that fills shown in figure is ripple box, but the inventor has also expected filling exhaust component can make by having flexible rubber, thereby it can rely on the automatic expansion of self elasticity air-breathing is described at least one the first gas chamber exhaust, thereby and can under being subject to from the pressure of described control assembly, shrink for described at least one first gas chamber inflation.In addition, the inventor has also expected filling exhaust component can be for filling the air pump of exhaust, and control assembly can be electric switch.
Specific embodiment of the invention scheme has more than been described.Within the scope of the invention, can carry out various improvement, modification to above-mentioned embodiment.For example, can adopt various ways to combine feature of the present invention.
