In addition, 520 inboards, resettlement section at shell cap 500 are equipped with clutch ring 600.Clutch ring 600 contacts with rotating shaft 400 1 sides in the resettlement section 520 with being allowed a choice, and the rotation condition of rotating shaft 400 in particular section, is inserted contiguously with resettlement section 520 inner peripheral surfaces.
Be formed with contact site 640 in clutch ring 600 both sides in opposite directions.442 of the clutch projectioies of contact site 640 and the side edge part 440 that is housed in resettlement section 520 contact selectively, are formed on clutch ring 600 both sides with the shape of inside slight concave.
Specifically, contact site 640 is formed by the inside slight concave of the part of circular clutch ring 600 both sides ground, forms suitable in parallel to each other.
Thereby, clutch ring 600 is installed in resettlement section 520 after, clutch ring 600 outer peripheral faces except that contact site 640 closely contact with the inner peripheral surface of resettlement section 520, contact site 640 and resettlement section 520 inner peripheral surfaces are mutually across a certain distance.
Here, the distance between the contact site 640 of both sides is less than the distance between the clutch projection 442.Thereby during 440 rotations of the side edge part of 520 inboards, resettlement section, clutch projection 442 contacts with the particular section of contact site 640.
The position that is formed with contact site 640 is that door 2 is positioned at automatic close session when (angle between the end face of storage space and the door is about 20～0 ° section B), is advisable with beginning and clutch projection 442 position contacting.
With reference to the accompanying drawings operation principle of the present invention is described.
Fig. 6 adopts kraut refrigerator door open and-shut mode schematic diagram of the present invention.As shown in the figure, the user presses upper and lower with rotary door 2, closes the storage space 1 of kraut refrigerator with being allowed a choice.
During rotary door 2, door 2 rotation section can be divided into substantially and freely stops section A and close session B automatically.
The section that the gravity that freely stops section A and be door 2 and compression spring 300 elastic force of articulated mounting 10 inside balance each other in the process of rotary door 2 up and down, can make 2 to keep the state that stops.In addition, to be equivalent to storage space 1 end face and the angle of door between 2 be scope between 85～20 ° to this scope.
The gravity that automatic close session B is a door 2 is greater than articulated mounting 10 internal compression springs 300 flexible sections.If other damping piece is not set, then in this section, door 2 can be closed under the own wt effect consumingly.It is scope between 20～0 ° that the scope here is equivalent to hide angle between space 1 end face and the above-mentioned door 2.
Damping action to automatic close session is elaborated with reference to the accompanying drawings.
Fig. 7 is that the present invention's internal structure under the kraut refrigerator door closure state is partly cut schematic diagram; Fig. 8 is that the present invention's internal structure under kraut refrigerator door open state is partly cut schematic diagram.
As shown in the figure, under the state of door 2 open fully (the storage space end face forms 85 ° of angles with door), slide unit 200 is in the state of engagement fully with rotating shaft 400, and sliding cam 240 fully closely contacts mutually with the inclined plane of axis cam 420.
When the user downwards slowly rotates door 2, with the rotating shaft 400 of door 2 one side combinations can and door 2 rotate.Though the revolving force here can pass the slide unit 200 that contacts to rotating shaft 400, therefore slide unit 200 can not be rotated because slide protrusion 220 combines with sliding tray 160, and it rotatablely moves and is limited.
The axis cam 420 of rotating shaft 400 can with slide unit 200 sliding cams 240 state of contact under, move along the inclined plane.Because rotating shaft 400 mobile being restricted laterally, so slide unit 200 can move to the side.
When slide unit 200 moved, compression spring 300 was compressed.The elastic force here passes to rotating shaft 400 by slide unit 200, passes the opposite direction to rotating shaft 400 direction of rotation.
When constantly door 2 being rotated, sliding cam 240 constantly with axis cam 420 relative motions, slide unit 200 is pushed to the side, compress above-mentioned compression spring 300 constantly, make it to provide constantly elastic force in contrast to rotating shaft 400 direction of rotation.
When door 2 turned to and forms the position at 20 ° of angles with storage space 1 end face, the state that the leading section of sliding cam 240 and axis cam 420 is in contact with one another can not be pushed slide unit 200 to side again.
Thereby the elastic force of compression spring 300 can not further increase, and door 2 rotates, closes under the effect of deadweight, can not further obtain compressing the damping action of spring 300.
Damping action to automatic close session is elaborated with reference to the accompanying drawings.
Fig. 9 is a clutch projection and clutch ring status schematic diagram when adopting kraut refrigerator door of the present invention to rotate.As shown in the figure, continued to rotate door at 2 o'clock, door 2 enters automatic close session B through freely stopping section A.
When door 2 rotates in freely stopping section A, be housed in rotating shaft 400 1 sides of shell cap 500 resettlement sections 520, be in not and resettlement section 520 medial surface state of contact, the rotation of rotating shaft 400 only is compressed spring 300 and hinders, and 520 inboards can not be restricted and freely rotate in the resettlement section.
On the contrary, when door 2 arrival became the position at 20 ° of angles approximately with storage space 1 end face, a side that is housed in the rotating shaft 400 of 520 inboards, shell cap 500 resettlement sections began and resettlement section 520 interior side contacts.
Specifically, door 2 enters when stopping section B automatically, and with the rotating shaft 400 that door 2 rotates, to the outstanding clutch projection 442 in side, beginning comes in contact with the contact site 640 of the clutch ring 600 of shell cap 500 inboards from its side edge part 440.
When door 2 continued to rotate, rotating shaft 400 can rotate by counter clockwise direction (being as the criterion with Fig. 9), thereby can compress and the rotating shaft 400 clutches projection 442 clutch rings that contact 600 contact sites 640.
Because clutch projection 442 has certain curvature.Therefore more to counterclockwise rotating, can make an appointment with and compress contact site 640 doughtily.The elastic force here can hinder the rotation of rotating shaft 400.
Be contact site 640 elastic force of clutch ring 600, because the shape facility of clutch projection 442, door 2 rotates more, and elastic force also can increase gradually.Along with door 2 is closed, the elastic force of increase passes to rotating shaft 400, the rotation of restriction rotating shaft 400.
The elastic force that contact site 640 produces can make door 2 close lentamente under the deadweight effect less than the gravity of door 2.
For open door 2, when door 2 was upwards rotated, the suffered resistance in same sector was identical, and promptly the elastic force of gate open overcompression spring 300 and contact site 640 obtains damping action in automatic close session.
Thereby articulated mounting 10 is in door 2 carries out up and down rotating process, and when door 2 was rotated in freely stopping section A, the rotation of the elastic force restriction rotating shaft 400 by compression spring 300 was to keep balance; When door 2 rotated in automatic close session B, by the elastic force of contact site 64, the rotation of restriction rotating shaft 400 played damping action.
