Embodiment
With reference to the accompanying drawings, the embodiment to the door switch of refrigerator of the present invention is elaborated.
Fig. 2 demonstrates the profile of door switch structure of the present invention.
As shown in the figure, hinge 20 is made of ring flange 22 and hinge axis 24.Above-mentioned ring flange 22 is fixed on the upper end or the bottom of refrigerator body one side; The above-mentioned hinge axis 24 of drum is formed on the bottom of above-mentioned ring flange 22.In addition, recessed hinge 40 is formed on the above and below of door, and above-mentioned hinge axis 24 is inserted.Door switch is arranged between above-mentioned hinge axis 24 and the recessed hinge 40.
Inner peripheral surface at above-mentioned recessed hinge 40 is provided with a pair of movable terminal 32a, 32b.Above-mentioned movable terminal 32a, 32b gives prominence to and is separated from each other formation along longitudinal direction in the inner peripheral surface part of above-mentioned recessed hinge 40; Above-mentioned movable terminal 32a, the end of 32b and external power source D1, D2 is connected, along with the opening/close of above-mentioned door switch, to lamp inside the box (not having in the accompanying drawing to show) power supply or the power supply that cuts off supply.In addition, above-mentioned movable terminal 32a, 32b has elasticity at the inner peripheral surface of above-mentioned recessed hinge 40 along vertical direction.In the present embodiment, though make a pair of above-mentioned movable terminal 32a, 32b is symmetricly set on the above-mentioned hinge axis 24, is not so certain.
On the one hand, the outer peripheral face at above-mentioned hinge axis 24 is provided with fixed terminal 34.Said fixing terminal 34 forms circular-arc; Said fixing terminal 34 possesses to be had corresponding to above-mentioned movable terminal 32a, a pair of moving part 34a that 32b forms along longitudinal direction, 34b.So, under the state of opening above-mentioned door D, said fixing terminal 34 and above-mentioned movable terminal 32a, 32b contact; Under the state of closing above-mentioned door D, said fixing terminal 34 and above-mentioned movable terminal 32a, 32b separates.In the present embodiment, corresponding to the above-mentioned a pair of movable terminal 32a that is symmetricly set on the above-mentioned hinge axis 24,32b, the moving part 34a of said fixing terminal 34,34b is symmetricly set on the hinge axis 24 equally.
In addition, above-mentioned movable terminal 32a, the material of 32b and fixed terminal 34 so long as conductor get final product.In the present embodiment, above-mentioned movable terminal 32a, 32b and fixed terminal 34 are formed by copper material.
Below, the work of the door switch of refrigerator of the present invention with said structure is elaborated.
Fig. 3 a demonstrates the profile of door switch structure of the present invention and door switching operating state.Fig. 3 b demonstrates the profile of door switch structure of the present invention and door switching operating state.
As shown in the figure, when closing the state of a D, make a pair of movable terminal 32a, 32b and a pair of moving part 34a that is arranged on the fixed terminal 34 on the hinge axis 24,34b lays respectively on vis-a-vis the position, above-mentioned a pair of movable terminal 32a, and 32b is arranged on the inner peripheral surface of recessed hinge 40.So, above-mentioned movable terminal 32a, 32b and moving part 34a, 34b does not have electrically connect, has closed door switch, and cut off and be attached at above-mentioned movable terminal 32a respectively, the external power source D1 of 32b one end, D2 closes lamp inside the box.
In addition, when opening above-mentioned D, above-mentioned door D is that the center is rotated according to certain angle with hinge axis 24, makes the above-mentioned movable terminal 32a that is arranged on above-mentioned recessed hinge 40 inner peripheral surfaces, and 32b is rotated with identical angle equally.So, above-mentioned movable terminal 32a, 32b from the moving part 34a of said fixing terminal 34,34b moves on the position vis-a-vis, contacts with said fixing terminal 34 to form electrically connect.Finally, can make respectively and above-mentioned movable terminal 32a, the external power source D1 that the end of 32b links, the electric current of D2 flows by fixed terminal 34, and open above-mentioned door switch is opened lamp inside the box.
When closing above-mentioned D again, make above-mentioned movable terminal 32a, 32b and fixed terminal 34 are separated from each other, and close above-mentioned door switch.So, said external power supply D1, D2 is cut off, and closes lamp inside the box again.
Below, variant embodiment is described.
Fig. 4 a demonstrates the profile of another embodiment of the present invention.Fig. 4 b demonstrates the plane graph of Fig. 4 a embodiment.
As shown in the figure, contact is provided with reveal axle sleeve 26 on the inner peripheral surface of above-mentioned recessed hinge 40, and the outer peripheral face contact of above-mentioned hinge axis 24 is provided with hinge side axle sleeve 28.Above-mentioned reveal axle sleeve 26 and hinge side 28 axle sleeves form the drum of thin thickness; Inner peripheral surface at above-mentioned reveal axle sleeve 26 is provided with above-mentioned movable terminal 32a, 32b; Outer peripheral face at above-mentioned hinge side axle sleeve 28 is provided with said fixing terminal 34; Constitute above-mentioned door switch.
In the present embodiment, because with movable terminal 32a, 32b and fixed terminal 34 are separately positioned on the above-mentioned reveal axle sleeve 26 and hinge side axle sleeve 28 of independent making, compare with directly door switch being arranged between above-mentioned hinge axis 24 and the recessed hinge 40, can make the setting of door switch easier.
As mentioned above, basic fundamental thought of the present invention is between hinge axis 24 and recessed hinge 40 door switch to be set.
Up to the present, though be that the center has been described in detail to embodiments of the invention, the personnel that have general knowledge in the technical field of the invention can propose a lot of distortion in basic fundamental thought range of the present invention.Basic fundamental thought of the present invention is embodied in patent and asks for protection in the scope, and all differences point in the equal with it scope all should be interpreted as belonging to scope of the present invention.
