The specific embodiment

With reference to the accompanying drawings the preferred embodiments of the present invention are explained:

The claimed rotary type refrigerator small door of the present invention is a refrigerator door that can independently open and close; its refrigerator door different from the past can only be with one side of door body axis rotate to open unfolding mode; but can Unscrew; also different and refrigerator door in the past can only be the version that a whole gate body is covered the whole storeroom of refrigerator; but be positioned on the gate body of refrigerator; it is the part of refrigerator gate body; it can independently open and close; also can open and close with gate body one; cover refrigerator storeroom jointly with refrigerator gate body; the user can open the refrigerator gate and pick and place article; also can under the situation of not opening the gate, directly open wicket and pick and place some article commonly used, use very convenient.

With reference to accompanying drawing 1-4, rotary type refrigerator small door body 2 of the present invention is a rectangle, be installed on the refrigerator gate body 1, it is the part of refrigerator gate body, but not with the gate body by integral forming, but being arranged in the rectangular aperture of being opened on the refrigerator gate body 8, the lower edge point midway is rotationally connected in little rotating shaft by lower edge point midway on it and the body rectangular aperture place, gate, realizes its rotary opening closing on the gate body.On a side of refrigerator inside, be provided with rack 9 at wicket body 2.

The be rotationally connected structure of part of wicket body and gate body is the key that guarantees that the rotating open-close function of wicket body can realize smoothly.The position that the lower edge mid point aligns on the wicket body respectively is processed with little rotating shaft 3, and this little rotating shaft is a kind of button rotating shaft that can stretch up and down.Its structure is: the midpoint of lower edge respectively has an aperture groove 5 on the wicket body, and hole slot 5 can also can be square column type for cylindrical.Be equipped with a column spring 6 in hole slot 5, its height is less than the degree of depth of hole slot, and its external diameter size is can be full of cross section in the hole slot but do not contact with the hole slot wall and be advisable.Fixedly connected with the bottom of hole slot 5 in the lower end of spring 6, the upper end of spring 6 is fixedly connected with a small convex pillar 4.The height of projection 4 and the spring 6 height sum under nature is greater than the degree of depth of hole slot 5, then at spring 6 in the raw the time, projection 4 stretches out outside the hole slot 5 in the support lower part of spring 6, part is stayed in the hole slot 5, two parts axis of projection inside and outside hole slot is concentric, and the junction forms ladder.It is the cylinder bodily form that projection 4 stretches out the outer part of hole slot, its external diameter is slightly less than the internal diameter of hole slot 5 (if hole slot 5 cross sections are square, then its external diameter is slightly less than hole slot square cross section inscribe diameter of a circle), the shape of cross section of projection 4 part in hole slot 5 and size are consistent with the shape of cross section and the size of hole slot 5, be that hole slot is cylindrical, projection part within it is almost onesize cylindrical, hole slot is a square column type, projection part within it is almost onesize square column type just also, hole slot and the projection in it mate mutually, the two leaves slight void, and projection can slide in hole slot.Stay a fixedly connected finger 17 on the part of hole slot 5 at projection 4, finger 17 and projection vertical fixing place the vertical slotted hole of opening on hole slot 5 sidewalls 18.Vertically slotted hole 18 is positioned at the surface of wicket body towards refrigerator inside one side, with hole slot 5 vertical communicating, its width is consistent with finger 17 external diameters size, and height is highly consistent with projection 4, finger 17 can vertically vertically move up and down in the slotted hole 18, and the wicket surface is stretched out in the end of finger 17.Projection 4, spring 6, hole slot 5, finger 17 and vertical slotted hole 18 have constituted the little rotating shaft 3 on the lower edge on the wicket body 2 jointly.

For making the slip of projection 4 in hole slot 5 more freely smooth and easy, more when preventing that wicket from rotating because the effect of moment produces relative rotation projection 4 and hole slot 5, should process in the little rotating shaft 3 and can guarantee that projection vertically slides along hole slot, prevent the chute 11 (not shown among Fig. 4) that projection and hole slot produce relative rotation.As shown in Figure 5, be processed with the vertical convex tendon of some up/down perforations 10 on the lateral wall of part in projection 4 is stayed hole slot 5, each convex tendon 10 is parallel to each other around the projection periphery and equidistantly distributes.Correspondingly, be processed with vertical chute 11 in the stroke range of projection on hole slot 5 inwalls, the chute on the hole slot inwall is corresponding one by one with convex tendon on the projection outer wall, cooperatively interacts.When projection 4 slides in hole slot 5, convex tendon 10 is stuck in the chute 11 of hole slot, make projection 4 in hole slot 5, vertically to slide, can not rotate with respect to the hole slot wall, and chute is equivalent to the slideway that projection slides in hole slot, can make the slip of projection in hole slot smoothly smooth and easy, make things convenient for fitting operation.

The little rotating shaft of this kind button structure at lower edge point midway place can be pressed under bearing the situation of extraneous extruding force in the hole slot on the wicket body on the wicket body, and this moment, the sideline, last lower edge of wicket was straight, did not have thrust on it; When the external force on acting on little rotating shaft was cancelled, under the effect of spring force, little rotating shaft meeting was upspring automatically, becomes the rotating shaft in the sideline, last lower edge that protrudes in wicket.

For the needs of wicket body are installed, the lower edge midpoint also will respectively be processed a cylindrical hole 7 on refrigerator gate body opening 8, the external diameter of the slightly larger in diameter in hole 7 small convex pillar 4 on the wicket body, the degree of depth in hole 7 is greater than the height of projection 4 extension from the wicket body, so that the little rotating shaft on the wicket on the lower edge can be ccontaining fully with the gate body on the hole in, realize that refrigerator gate body is connected with the tight of wicket body on it.

For make wicket rotation more freely, reduce the frictional resistance of rotating shaft in hole 7, can between little rotating shaft and hole 7 inwalls, be processed with little bearing.

Be wicket body around the lower edge midpoint rotating shaft of minimizing wicket and the wearing and tearing between the gate body, can fix an annular protection pad in the periphery of gate, junction, lower edge body opening 7 or the periphery of wicket body projection 4, this annular protection pad should be selected and door body storeroom coefficient of friction materials with smaller.More can on this annular protection pad, process a shallow annular groove, position with respect to shallow grooves on the door body that does not have protection pad of its correspondence processes a salient point, the wicket rotation time slides salient point in shallow grooves, with between effective minimizings body because of mutual fricative wearing and tearing.

The structure of the big wicket body of this kind refrigerator coupling part is convenient to the installation of wicket body, the workman is when installing the gate body with the wicket body, finger under only needing to dial on the wicket body side surface, make in the small convex pillar retraction hole slot of lower edge midpoint on the wicket body, wicket is placed gate body opening,, unclamp finger the position alignment in hole on the position of projection and the gate body, projection will lift automatically and stretch in the hole, and the wicket body is connected on the gate body.Finger just can take off the wicket body projection retraction hole slot also only to need to dial down when unloading the wicket body.The design of this syndeton makes that the installation of refrigerator small door is very easy, has avoided being installed in wasting time and energy of fitting operation in the big door opening with the integrated fixed rotating shaft of wicket.The central rotating shaft of refrigerator small door is connected to the switching that rotates freely that promptly can realize wicket on the gate body.

Refrigerator small door of the present invention is positioned on the refrigerator gate body, is the part of refrigerator gate body, then between wicket body and gate body good sealing must be arranged, and could effectively avoid increases the problem of energy consumption of refrigerator owing to having opened a door body more.Rotary wicket body is different from the common door body for the requirement of seal member, can not adopt and install sealing strip around the body inboard additional and be adsorbed on sealing means on the refrigerator frame outside, but between edge, wicket body surrounding and edge, body opening part surrounding, gate, seal member be installed, make seal member can guarantee around the wicket body sealing with body junction, gate, do not hinder the rotation of wicket body again, this has just proposed requirement to the structure of seal member.

As shown in Figure 6, on the edge around gate body opening 8 places, seal member is installed, the sealing parts are along a whole circle sealing gasket 12 that encases with body opening part surrounding, gate, a few parallel shallow grooves 13 are arranged on the sealing pad, the spacing that shallow grooves is 13 equate and on the edge position be symmetrical arranged, correspondingly, a few parallel short convex ribs 14 of processing on edge, wicket body surrounding, its surrounding was corresponding one by one with the shallow grooves on the gate body sealing gasket along last short convex rib when the wicket body was closed, and placed in the shallow grooves.In this kind hermetically-sealed construction, the concaveconvex structure of sealing gasket on the gate body and wicket contact portion has guaranteed the effect of sealing.Simultaneously, because the degree of depth of sealing gasket upper groove 13 is not dark, the material of sealing gasket is again an elastomeric material, only need when then opening the rotation wicket one to push away gently, convex tendon 14 around the wicket body just can spin off from the groove 13 on the gate body sealing gasket 12, also only need touching wicket one side when closing wicket, just can to make convex tendon 14 on the wicket snap in groove again interior 13, and seal member does not influence the rotating open-close of wicket fully.Certainly, as the further improvement of sealing structure, wicket body surrounding along on wrap the sealing gasket of band convex tendon, match with the sealing gasket of band groove on the gate body, can reach better sealing effectiveness.

Than the better technical scheme of above-mentioned hermetically-sealed construction sealing effectiveness is to install the profiled seal bar additional between wicket body and gate body.As shown in Figure 7, rectangular stepped sealing strip 15 is installed on edge, the wicket body left and right sides, the shape size of the stepped sealing strip of wicket body left and right sides is consistent, the overbending direction unanimity of ladder, be all clockwise or be all counterclockwise, crooked place is at about 1/3 place of sealing strip width, and promptly the narrow interior side steps of the outer side steps of ladder bending place is wide.Correspondingly, rectangular stepped sealing strip is installed on the edge, the left and right sides of gate body opening part, the shape and the width of sealing strip are identical on the shape of sealing strip and width and the wicket body, the overbending direction of sealing strip is corresponding on direction and the wicket body of bending, and its integral installation position was with respect to the vertical center line two lateral balances concord in door body edge when the sealing strip on sealing strip on the gate body and the wicket body cooperatively interacted.The sealing of lower edge still can be joined the seal member with concaveconvex structure in the foregoing description on the wicket body.

When wicket is in closed condition, the adhesive of arranging in pairs or groups mutually of the sealing strip of the sealing strip of wicket both sides and opening part both sides, gate, because the bending of sealing strip on width is more, it is better that its sealing effectiveness is wanted.When the user pushes wicket Rotate 180 degree open and picks and places article, because the symmetry of gasket structure, though wicket has rotated 180 degree, but the sealing strip of its both sides can closely cooperate with the sealing strip on the gate body equally, the user still can realize good sealing between wicket body and the gate body when picking and placeing article like this.Difference except sealing effectiveness, the difference of sealing structure and above-mentioned hermetically-sealed construction also is the location of wicket rotation: the sealing structure can only make wicket rotarily open 180 degree to a direction, can realize backstop location to wicket, the wicket of above-mentioned hermetically-sealed construction can rotate arbitrarily, be not easy the location, the two cuts both ways, and can select as required to use.

The external side that can inwardly advance of wicket on this refrigerator gate body is provided with handle 16, the user touches handle when picking and placeing article, wicket promptly rotarily opens, after rotating to 180 degree, the user picks and places article on rack 9, this moment, wicket was in the state with gate upper shed complete closed, had stoped leaking of the interior cold air of refrigerator effectively.The rotary type refrigerator small door that the present invention is claimed has made things convenient for the user to pick and place the interior article commonly used of refrigerator, has more effectively reduced the energy consumption of refrigerator, and is not only convenient but also energy-conservation.

For the novelty and the aesthetic property that increase in the refrigerator moulding also can be done wicket of the present invention circular or other different figures, all in protection scope of the present invention.
