Abstract

The invention discloses an refrigerator which comprises a body provided with a refrigerating chamber, a door, an assisting mechanism, a cam and a handle. The door is connected with refrigerating chamber, used for opening and closing the same and located on the front side of the body. The assisting mechanism comprises a first pivot shaft disposed on the door. The axial direction of the first pivot shaft is parallel with the front end face of the body. The cam is pivotably disposed on the first pivot shaft, so that the cam can be butted against the body and separate the door and the body when the cam rotates to a preset position. The handle is connected with the cam to drive the same to pivot. By the assisting mechanism disposed on the door, a force of the door pushing the body can be converted through the cam, and accordingly drawers can be opened with small force, and the problem that the door of a large refrigerator needs large force to be opened is solved.

Shown in Fig. 1-4, refrigerator 100 according to an embodiment of the invention, comprising: casing 10, door body 20 and servomechanism 30.
Particularly, casing 10 can have chamber 11 between refrigeration.Chamber 11 can be refrigerating chamber or refrigerating chamber between refrigeration.
Door body 20 is connected to open and close chamber 11 between refrigeration with casing 10, and door body 20 is positioned at the front side of casing 10 with the opening of chamber 11 between the sealing refrigeration.
Servomechanism 30 can comprise: the first pivotal axis 31, cam 32 and handle 33.
Particularly, the first pivotal axis 31 can be located on the body 20, and the axial direction of the first pivotal axis 31 is parallel with the front end face 11 of casing 10.
Cam 32 is established on the first pivotal axis 31 pivotly, with when cam 32 rotates to the precalculated position with casing 10 against and promote casing 10 so that the door body 20 separate with casing 10, with the thrust by 32 pairs of casings 10 of cam, reduce to beat the power of opening door body 20 required uses.
Handle 33 is connected to be with moving cam 32 to pivot with cam 32.For example handle 33 can be located at the front side of a body 20, is with moving cam 32 to pivot to make things convenient for the user to pass through swing handle 33.
Refrigerator 100 according to an embodiment of the invention, by at door body 20 servomechanism 30 being set, convert the power that a body 20 pushes away casing 10 to by cam 32, thereby use very little power that drawer is opened, thus, can solve a problem that the very large power of body needs just can be opened of large-scale refrigerator 100.
As shown in Figures 2 and 3, according to one embodiment of present invention, handle 33 comprises: handle portion 331 and connecting portion 332.
Particularly, handle portion 331 is positioned at the front side of a body 20, to be user-friendly for operation.One end of connecting portion 332 is connected with handle portion 331, and the other end is connected with cam 32.Thus, can conveniently control by 331 pairs of cams 32 of handle portion.
Shown in Fig. 2-4, according to one embodiment of present invention, servomechanism 30 may further include: the second pivotal axis 34.
The second pivotal axis 34 can be located on the body 20, the axis direction of the second pivotal axis 34 is parallel with the axial direction of the first pivotal axis 31, connecting portion 332 is located on the second pivotal axis 34 pivotly, and the other end of connecting portion 332 is connected by connecting axle 35 pivotly with cam 32.Thus, can make things convenient for handle 33 to pivot around the second pivotal axis 34, in handle 33 rotation processes, can be with moving cam 32 to pivot, convert cam 32 to the revolving force with handle 33 and act on top power on the casing 10, so that a door body 20 is opened with respect to casing 10.
As shown in Figures 2 and 3, according to one embodiment of present invention, the axis direction of connecting axle 35 is parallel with the second pivotal axis 34 with the first pivotal axis 31, and connecting axle 35 is located at an end of cam 32.Thus, can make things convenient for 32 rotations of handle 33 band moving cams.
Such as Fig. 2-shown in Figure 4, according to one embodiment of present invention, the other end of connecting portion 332 has the strip through hole 3321 that is suitable for being socketed on the connecting axle 35.Thus, can reduce handle 33 suffered resistance in moving process, make things convenient for the user to operate.
As shown in Figure 1, according to one embodiment of present invention, the top end face of door body 20 is provided with along groove 21, the first pivotal axis 31, the second pivotal axis 34 and the connecting axle 35 of fore-and-aft direction rear opening body 20 and is positioned at groove 21.Thus, this setup can not affect the outward appearance of refrigerator, refrigerator is driven more attractive in appearance.
As shown in Figure 1, further, handle portion 331 is the cross bar of horizontally set, and connecting portion 332 is extended respectively along the axial equidirectional of vertical and cross bar in the two ends of cross bar.Thus, the user can by on lift or press down the rotation that cross bar just can realize controlling cam 32.
According to one embodiment of present invention, the inboard of door body 20 is provided with the guide rail (not shown) that arranges along fore-and-aft direction, and guide rail slides along the madial wall of chamber 11 between refrigeration, so that door body 20 opens and closes chamber 11 between refrigeration.
According to one embodiment of present invention, door body 20 is connected pivotly with casing 10.
Shown in Fig. 2-4, according to one embodiment of present invention, cam 32 comprises connecting rod 321 and is positioned at the edge drive division 322 that reduces gradually of curvature in the counterclockwise direction of an end of connecting rod 321.Thus, can be by drive division 322 effects and casing 10, to finish the operation of beating opening door body 20.
Below with reference to Fig. 2 and Fig. 3 according to an embodiment of the invention door body 20 opening procedures of refrigerator 100 are described.
As shown in Figure 2, at this moment, the door body 20 of refrigerator 100 is under the normal closed condition, when needs are opened the door body 20 of refrigerator 100, with shown in Figure 3, when carrying out opening door operation, utilize handle 33 to open the door power that forward direction presses down, convert the power that a body pushes away casing to by cam 32, thereby use very little power just to realize the purpose that a body is opened.Situation when Fig. 2 closes for door body 20, handle 33 resets to reset condition, and cam does not contact with casing 10 in door body 20 for 32 this moments:
When external force downward direction in Fig. 3, Fig. 4 applies, handle 33 can be along the first pivotal axis 31 rotations that are fixed on the body 20, rotate by handle 33 and band moving cam 32, the outer rim of cam 32 is irregular cycle, curvature gradually changes, thereby can contact or push with casing 10 respectively when rotating to diverse location, and the revolving force on the handle 30 be converted to the top power at this place, door body 20 is backed down.
In the description of this specification, the description of reference term " embodiment ", " some embodiment ", " illustrative examples ", " example ", " concrete example " or " some examples " etc. means to be contained at least one embodiment of the present invention or the example in conjunction with specific features, structure, material or the characteristics of this embodiment or example description.In this manual, the schematic statement of above-mentioned term not necessarily referred to identical embodiment or example.And the specific features of description, structure, material or characteristics can be with suitable mode combinations in any one or more embodiment or example.
Although illustrated and described embodiments of the invention, those having ordinary skill in the art will appreciate that, in the situation that do not break away from principle of the present invention and aim can be carried out multiple variation, modification, replacement and modification to these embodiment, scope of the present invention is limited by claim and equivalent thereof.
