Technical Field

The invention relates to a refrigeration and freezing technology, in particular to a handle assembly for a refrigeration and freezing device and the refrigeration and freezing device.

Background

Handles on existing refrigeration and freezing devices such as refrigerators include a light handle and a dark handle. The exposed handle is an arc-shaped or straight handle protruding out of the plane of the refrigerator door body and is fixed through fixing bolts at two ends. However, the whole handle is exposed outside the door body, the space size of the mounting position of the handle is larger, the overall dimension of the refrigerator is increased, and therefore the gradually-increased products with the handles are fewer. Refrigerators with hidden handles begin to appear in large numbers, and the common hidden handles are formed by inwards recessing a door body of the refrigerator to form a gap which can be used as a buckle. However, due to the limitation of the thickness of the foaming layer, the space of the gap between the handles is very small, and more seriously, the hidden handle needs to be embedded in the door body, occupies the volume of the foaming layer of the door body, can reduce the heat insulation performance of the door body, and is easy to generate condensation. In addition, in order not to influence the heat preservation function of the foaming layer, the recessed part occupies the volume inside the refrigerator, so that the available volume of the refrigerator is reduced.

Detailed Description

The embodiment of the invention firstly provides a handle assembly for a refrigerating and freezing device, and the handle assembly is arranged on a door body of the refrigerating and freezing device. Fig. 1 and 2 are schematic block diagrams of a handle assembly according to an embodiment of the present invention in different states, and fig. 3 and 4 are schematic exploded views of different orientations of the handle assembly according to an embodiment of the present invention. Referring to fig. 1 to 4, a handle assembly 1 of an embodiment of the present invention includes a base 10 and a handle 20. The base 10 is fixed on the outer surface of the door body of the refrigerating and freezing device, and is provided with a mounting part 110 which is concave towards the inside of the door body, namely, the mounting part 110 is concave backwards. The handle 20 is selectively accommodated in the installation part 110 on the base 10, so that the whole handle assembly 1 is located outside the door body, the door body is only required to be provided with a very small installation space for the handle assembly 1 or even is not required to be concave for the design of the handle assembly 1, the thickness of a door body foaming layer is not reduced to influence the heat insulation performance of the door body, and the inner side of the door body is not bulged to occupy the storage space inside the refrigeration device.

Further, the first end 210 of the handle 20 is pivotally connected to the mounting portion 110, and the second end 220 is configured to operatively slide between a first position and a second position in the mounting portion 110, such that the handle 20 is received in the mounting portion 110 when it is in the first position (see the state shown in fig. 1), and such that the handle 20 is elastically deformed and arched toward the outside of the mounting portion 110 when it is in the second position (see the state shown in fig. 2, which may be arched, for example). That is, the position of the first end 210 of the handle 20 is relatively fixed, and the position of the second end 220 of the handle 20 relative to the first end 210 can be changed by an external force. I.e., second end 220, is operatively slidably coupled to mounting portion 110, thereby allowing handle assembly 1 to assume both a use and a rest position. When the door is in use, a user can directly pull the handle 20 outwards to enable the second end 220 to slide to the second position, so that the handle 220 is in a shape of being arched towards the outer side of the mounting portion 110, the handle is convenient for the user to hold, and the user can apply larger acting force capable of opening the door body to the handle 20; in the resting state, when the user releases the handle or pushes the handle 20 slightly, the second end of the handle 20 slides back to the first position, so that the entire handle 20 is accommodated in the mounting portion 110. That is, the handle 20 is extended only in the use state, and does not occupy an additional space in the rest state, thereby reducing the space occupied by the entire handle assembly 1, and thus making the space occupied by the refrigerating and freezing apparatus using the handle assembly 1 smaller.

The handle 20 is made of a material selected so as to be elastically deformed by an external force, and can be restored to its original shape when the external force disappears. Specifically, the handle 20 may be made of an elastic material such as silicone, rubber, or the like.

The connection line between the first position and the second position of the handle second end 220 is parallel to the extension direction of the handle 20 itself. Specifically, the base 10 and the handle 20 are each substantially an elongated member that is placed vertically, and the mounting portion 110 in the base 10 is also substantially an elongated cavity that matches the shape of the handle 20. The first end 210 of the handle 20 may be the upper end and the second end 220 may be the lower end. The connection line between the first position and the second position of the handle second end 220 extends in a vertical direction.

Fig. 5 is a schematic sectional view taken along a vertical sectional plane of the handle assembly shown in fig. 1, fig. 6 is a schematic sectional view taken along a vertical sectional plane of the handle assembly shown in fig. 2, fig. 7 is a schematic enlarged view of a portion C in fig. 6, and fig. 8 is a schematic enlarged view of a portion D in fig. 6. Referring to fig. 3 to 8, in some embodiments of the present invention, the mounting portion 110 has first and second shaft pins 1111 and 1121 provided therein corresponding to the first and second ends 210 and 220 of the handle 20, respectively. The first end 210 of the handle 20 is provided with a pivot hole 211 for pivoting with the first pivot 1111, and the first pivot 1111 is inserted into the pivot hole 211. The second end 220 of the handle 20 is provided with a strip-shaped sliding slot 221 for slidably connecting with the second shaft pin 1121 so that the second shaft pin 1121 is at a first end of the sliding slot 221 when the second end 220 of the handle 20 is at the first position and the second shaft pin 1121 is at a second end of the sliding slot 221 when the second end 220 of the handle 20 is at the second position. Specifically, the second shaft pin 1121 may be inserted into the sliding groove 221 and may slide along the sliding groove 221 by an external force. The sliding slot 221 extends parallel to the line connecting the first position and the second position, i.e. parallel to the direction of extension of the handle 20 itself.

Further, the mounting portion 110 is provided therein with a first connector 111 and a second connector 112, and the first connector 111 and the second connector 112 are located at positions corresponding to the first end 210 and the second end 220 of the handle 20, respectively. The first shaft pin 1111 is formed on the first link 111, and the second shaft pin 1121 is formed on the second link 112. Specifically, the mounting portion 110 may be respectively provided with a groove at a position adjacent to the upper end portion and the lower end portion thereof, and the first connecting member 111 and the second connecting member 112 are respectively disposed in the two grooves to limit the first connecting member 111 and the second connecting member 112, so as to effectively prevent the first connecting member 111 and the second connecting member 112 from shaking.

In some embodiments of the present invention, the first connector 111 and the second connector 112 may be fixedly connected to the bottom wall of the mounting portion 110. Specifically, each recess of the mounting portion 110 may have a coupling hole formed therein, which may be a threaded hole, for example. The first connecting member 111 may include a supporting platform 1112 supported on and fastened to the bottom wall of the mounting portion 110, and a protrusion 1113 disposed on the supporting platform 1112. The supporting platform 1112 is also provided with a connecting hole to fasten the first connecting member 111 to the bottom wall of the mounting portion 110 by a connecting member passing through the corresponding connecting holes of the supporting platform 1112 and the bottom wall of the mounting portion 110. The second connecting member 112 has the same structure as the first connecting member 111, and similarly includes a supporting platform 1122 supported on and fastened to the bottom wall of the mounting portion 110, and a bump 1123 provided on the supporting platform 1122, and the supporting platform 1122 is also fastened to the bottom wall of the mounting portion 110 by a connecting member, which may be a screw, for example.

In some alternative embodiments of the present invention, the first connector 111 and the second connector 112 may also be integrally formed with the bottom wall of the mounting portion 110.

Further, the number of the first shaft pins 1111 and the second shaft pins 1121 is two. The two first pivot pins 1111 are formed on two opposite and parallel surfaces, e.g., two lateral sides, of the projection 1113, respectively. Two second shaft pins 1121 are respectively formed on two opposite and parallel surfaces, e.g., two lateral sides, of the projection 1123 of the second connection member 112. Thereby, the pivoting of the handle first end 210 and the sliding of the handle second end 220 can be made smoother and smoother.

In some embodiments of the present invention, the inner side of the first end 210 of the handle facing the bottom wall of the mounting portion 110 is provided with a first cavity 212 recessed in a direction away from the bottom wall of the mounting portion 110 (for example, the first cavity 212 may be recessed forward), and two opposite side walls of the first cavity 212 are respectively provided with a pivot hole 211. The top end of the first connecting member 111 (for example, the protrusion 1112 of the first connecting member 111) is inserted into the first cavity 212, and the two first pivot pins 1111 are inserted into the two pivot holes 211, respectively.

In some embodiments of the present invention, the inner side of the second end 220 of the handle facing the bottom wall of the mounting portion 110 is provided with a second cavity 222 recessed in a direction away from the bottom wall of the mounting portion 110 (for example, the second cavity 222 may be recessed forward), and two opposite side walls of the second cavity 222 are respectively provided with a sliding groove 221. The top end of the second connecting member 112 (for example, the protrusion 1122 of the second connecting member 112) is inserted into the second cavity 222, and the two second shaft pins 1121 are respectively inserted into the two sliding slots 221.

In some embodiments of the present invention, the pivot hole 211 may be a through hole penetrating through the first end 210 of the handle in a direction perpendicular to a connection line between the first position and the second position. The sliding slot 221 is a through slot passing through the second end 220 of the handle in a direction perpendicular to a connecting line between the first position and the second position. Specifically, in the embodiment shown in fig. 1 to 4, the pivot hole 211 is a through hole extending through the first end 210 of the handle along the transverse direction. The sliding slot 221 is a through slot extending in the vertical direction and transversely penetrating the second end 220 of the handle.

In some embodiments of the present invention, the second end of the sliding slot 221 is provided with a recess 2211, so that the second shaft pin 1121 is caught in the recess 2211 when the second end of the handle 20 is at the second position, thereby preventing the handle 20 from being restored to the original state by its own elastic force after being elastically deformed. That is to say, when the second end 220 of the handle 20 is located at the second position, the second shaft pin 1121 can be inserted into the recess 2211, so as to prevent the user from having to use the handle 20 after the handle 20 is elastically deformed, and the handle 20 is restored to the original shape under the action of its own elastic force, thereby improving the user experience.

In some embodiments of the present invention, the handle assembly 1 further comprises two

covers

310 and 320, and the two

covers

310 and 320 are respectively covered on the first end 210 and the second end 220 of the handle 20 to prevent the first connecting member 111 and the second connecting member 112 from being separated from the handle 20. Specifically, the outer side surfaces of the outer covers 310 and 320 facing away from the mounting portion 110 are continuous and flat surfaces, and the inner side surfaces opposite to the outer side surfaces are provided with notches to allow the protrusion 1113 of the first connecting member 111 and the protrusion 1123 of the second connecting member 112 to be inserted into the first cavity 212 of the first end 210 of the handle and the second cavity 222 of the second end 220 of the handle through the notches, respectively.

Further, the portion of the handle 20 between the first end 210 and the second end 220 thereof forms a step surface with the boundary between the first end 210 and the second end 220, and the outer surfaces of the

housings

310, 320 are flush with the outer surface of the portion of the handle 20 between the first end 210 and the second end 220, thereby contributing to the aesthetic appearance of the entire handle assembly 1.

In some embodiments of the invention, the base 10 also has a relief hole or slot 119 for a user to apply a pushing or pulling action to the handle 20. Specifically, the dimension of the groove of the mounting portion 110 corresponding to the second end 220 of the handle in the direction parallel to the extending direction of the handle 20 itself is larger than the dimension of the second end 220 of the handle in the direction, so that a yielding space is formed between the second end 220 of the handle 20 and the side wall of the mounting portion 110 when the handle 20 is accommodated in the mounting portion 110 (i.e. in a resting state). The user may place a finger in the abduction space to facilitate application of pushing force to the handle second end 220.

In some alternative embodiments, two offset holes may be formed on the lateral side wall of the base 10 defining the mounting portion 110, so that the user can pull the handle 20 through the two offset holes.

In alternative embodiments of the present invention, the mounting portion 110 may also have a pivot hole and a bar-shaped sliding slot therein, which correspond to the first end 210 and the second end 220 of the handle 20, respectively. Accordingly, the first end 210 of the handle 20 is provided with a first shaft pin for being pivotally connected with the pivot hole, and the first shaft pin is inserted into the pivot hole. The second end 220 of the handle 20 is provided with a second pin for slidable connection with the bar-shaped chute such that the second pin is at the first end of the chute when the second end 220 of the handle 20 is in the first position and the second pin is at the second end of the chute when the second end 220 of the handle 20 is in the second position. That is, in some alternative embodiments, the positions of the pivot hole and the first axle pin can be interchanged, and the positions of the sliding slot and the second axle pin can be interchanged, so long as the first end 210 of the handle is pivotally connected to the mounting portion 110 and the second end 220 of the handle is slidably connected to the mounting portion 110.
