Referring to fig. 2 to 9, according to an embodiment of the present invention, a buckle assembly of a refrigeration device is provided, which includes a buckle body 101 and a connecting member. The handle body 101 is used for being arranged at an interval with a panel 103 of a drawer in the refrigeration equipment and forming a handle slot 105 with the panel 103, and the handle body 101 is provided with an air guide surface 1011 for guiding air flow between the panel 103 and the handle body 101; the connector connects the clasp body 101 to the faceplate 103.

The phrase "the handle body 101 is spaced from the panel 103 of the drawer inside the refrigeration device" means that when the handle body 101 is mounted on the panel 103, a gap is formed between the handle body 101 and the panel 103 to allow the airflow to pass through.

In the handle assembly of the refrigeration equipment, the air guide surface 1011 which guides the air flow between the panel 103 and the handle body 101 is formed on the handle body 101, so that the air flow can pass between the panel 103 of the drawer and the handle body 101 and blow away the moisture accumulated near the handle assembly, thereby preventing the handle assembly from frosting or condensation. When the handle component is mounted on the panel 103 of the drawer, the handle groove 105 is formed between the panel 103 and the handle body 101, the top of the handle groove 105 forms an air guide opening, the bottom of the handle groove 105 forms an air outlet, and then air flow enters the handle groove 105 through the air guide opening to take away moisture in the handle groove 105 and prevent the handle groove 105 from frosting or dewing.

In one embodiment, referring to fig. 2 and 3, the connecting member includes a first torsion spring 107 and a second torsion spring 109, the first torsion spring 107 and the second torsion spring 109 are disposed on two sides of the handle body 101, and each of the first torsion spring 107 and the second torsion spring 109 includes a first spring arm and a second spring arm, the first spring arm is fixed to the handle body 101, and the second spring arm is fixed to the panel 103. Of course, the first spring arm does not have to be fixed to the buckle body 101, and the second spring arm does not have to be fixed to the panel 103 when the torque is applied to the buckle body 101.

Through the arrangement of the first torsion spring 107 and the second torsion spring 109, the elastic touch feeling when the handle body 101 is operated can be adjusted based on the torque of the first torsion spring 107 and the second torsion spring 109, and the operation experience of a user is improved.

Specifically, the handle component is disposed on the panel 103 of the drawer, and when the user pulls out the drawer, the handle body 101 can rotate under the action of the first torsion spring 107 and the second torsion spring 109 to provide elastic feedback for the user, so as to increase the user experience. When the hand of the user leaves from the buckle body 101, the buckle body 101 automatically returns to the initial position under the action of the first torsion spring 107 and the second torsion spring 109, and the buckle body 101 maintains a large upper opening angle under the action of the torsion of the first torsion spring 107 and the second torsion spring 109. When the drawer is withdrawn, the larger opening angle above the handle body 101 is beneficial to the air flow to pass through, so that the moisture entering the refrigerator is blown away when the door is opened, and the problem of frosting or condensation caused by moisture accumulation is avoided.

When the first torsion spring 107 and the second torsion spring 109 are provided, a first protector 111 and a second protector 113 may be further provided. Specifically, the handle assembly further comprises two first guard plates 111 and two second guard plates 113. The two first guard plates 111 and the handle body 101 enclose a first accommodating chamber of the first torsion spring 107; the two second guard plates 113 and the handle body 101 enclose a second accommodating chamber of the second torsion spring 109. Through the setting of backplate, not only can protect first torsion spring 107 and second torsion spring 109, can also guarantee the pleasing to the eye of attacker's subassembly.

It should be noted that the first guard plate 111 and the second guard plate 113 are both mounted on the panel 103 of the drawer, and further, a first accommodating chamber is formed between the first guard plate 111, the panel 103 and the catcher body 101, and a second accommodating chamber is formed between the second guard plate 113, the panel 103 and the catcher body 101.

The first guard plate 111, the second guard plate 113 and the handle body 101 may be made of plastic, for example, the first guard plate 111, the second guard plate 113 and the handle body 101 may be made of plastic, and the first torsion spring 107 and the second torsion spring 109 are respectively disposed inside the first accommodating chamber and the second accommodating chamber, so as to prevent the first torsion spring 107 and the second torsion spring 109 made of metal from being exposed.

Further, referring to fig. 3, 5 and 9, the first guard plate 111 and the second guard plate 113 are both arc-shaped on the sides facing the buckle body 101. Under the condition, the first guard plate 111 or the second guard plate 113 can be prevented from accidentally injuring a user in the operation process, and the use safety is ensured; it is also possible to facilitate the rotation of the catcher body 101 and prevent the first protector 111 and the second protector 113 from interfering with the rotation of the catcher body 101. Of course, the first shield 111 and the second shield 113 may have any other shape.

In one embodiment, referring to fig. 6 and 7, when the first guard plate 111 and the second guard plate 113 are provided, the first mounting shaft 601 may be fixed between the two first guard plates 111 and the second mounting shaft 603 may be fixed between the two second guard plates 113. On the basis, the spring body of the first torsion spring 107 is sleeved outside the first mounting shaft 601, and the spring body of the second torsion spring 109 is sleeved outside the second mounting shaft 603. By the arrangement of the first and second mounting

shafts

601 and 603, the reliability of the mounting of the first and second torsion springs 107 and 109 can be ensured.

According to an embodiment of the invention, the connector may further comprise a hinge. Wherein, the hinge is used for rotatably arranging the handle body 101 on the panel 103. The handle component also comprises an elastic piece which is switched between a deformation state and a reset state. In the deformed state, the elastic member biases the buckle body 101 to the reset state, that is, the elastic member is pressed or pulled to deform in the deformed state, and once the external force is removed, the buckle body 101 rotates to the initial position under the action of the elastic member.

For example, in fig. 4 and 5, when the drawer is pulled outwards through the air guiding opening at the top of the buckle slot 105, the upper part of the buckle body 101 tends to be far away from the panel 103 of the drawer, and the lower part of the buckle body 101 tends to be close to the panel 103 of the drawer. Meanwhile, when the drawer is pulled outwards through the air guide opening of the buckle slot 105, the elastic member is deformed, and once the external force is removed, the elastic member causes the upper portion of the buckle body 101 to move towards the panel 103 and causes the lower portion of the buckle body 101 to move away from the panel 103.

Similarly, when the drawer is pulled outwards through the air outlet at the bottom of the buckle slot 105, the upper part of the buckle body 101 tends to be close to the panel 103 of the drawer, and the lower part of the buckle body 101 tends to be far away from the panel 103 of the drawer. Meanwhile, when the drawer is pulled outward through the air outlet of the catcher slot 105, the elastic member is deformed, and once the external force is removed, the elastic member causes the upper portion of the catcher body 101 to move away from the panel 103 and the lower portion of the catcher body 101 to move toward the panel 103.

In other words, when the drawer is pulled outwards through the air guide opening at the top of the handle slot 105, the handle body 101 rotates forwards; when the drawer is pulled through the air outlet at the bottom of the handle slot 105, the handle body 101 rotates reversely. The forward direction may be a clockwise direction or a counterclockwise direction.

Wherein, when the drawer is pulled through the catching groove 105, the elastic member is pressed or pulled depending on the installation position of the elastic member.

The elastic element can be a spring, a rubber rod or any object with elasticity.

In one embodiment, the air guide surface 1011 is a plane. In this case, the air guide surface 1011 is provided obliquely with respect to the drawer panel 103, and the distance between the air guide surface 1011 and the panel 103 becomes closer along the air guide direction, thereby ensuring that the air flow is guided between the panel 103 and the catcher main body 101. In addition, when the air guide surface 1011 is a flat surface, the structure of the buckle body 101 is simple and the manufacturing is easy. It is worth mentioning that, when wind guide surface 1011 is the plane, except that the air current can take away the moisture through wind guide surface 1011, even if gather a small amount of steam on wind guide surface 1011, steam also falls down along wind guide surface 1011 under the action of gravity easily, and then guarantees the cleanness of attacker's subassembly.

Of course, the air guide surface 1011 may also be an arc surface, or the air guide surface 1011 may also be formed by splicing a plurality of planes, or the air guide surface 1011 may also be an irregular surface, as long as the air flow is facilitated to enter the hand buckling groove 105 through the air guide opening.

In one embodiment, the buckle body 101 is integrally formed in a plate shape, so that the manufacturing cost of the buckle body 101 can be controlled. Of course, the buckle main body 101 may be in a block shape, a strip shape, or the like, as long as the air guide surface 1011 is formed on the buckle main body 101.

In one embodiment, the air guide surface 1011 is provided with guide ribs extending along the air guide direction. Through the setting of direction rib, not only can guarantee that the air current passes through air guide surface 1011, can also increase the frictional force with the hand in the operation, promote the sense of touch.

According to an embodiment of the present invention, there is also provided a drawer of a refrigeration device, which is located inside the refrigeration device, wherein the drawer includes a panel 103, and the above-mentioned handle assembly is mounted on the panel 103.

For the drawer of the refrigeration equipment, due to the arrangement of the buckle assembly, the buckle assembly does not frost or dew, and does not frost or dew in the area of the panel 103 for mounting the buckle assembly.

It can be seen from fig. 4 and 5 that the cross section of the gripping groove 105 is gradually reduced from top to bottom in a horizontal plane, i.e. the gripping groove 105 is obtained with a structural characteristic that is wide at the top and narrow at the bottom, so as to facilitate the air flow through the gripping groove 105.

For the refrigeration equipment, taking a refrigerator as an example, when the door 401 is closed, the airflow generally flows from top to bottom between the door 401 and the drawer, please refer to the arrow direction in fig. 5, so the latch slot 105 is designed to have a structure with a wide top and a narrow bottom. If the air flow of other types of refrigeration equipment is from bottom to top, the handle slot 105 can be designed to be narrow at the top and wide at the bottom. That is, the open side of the locking groove 105 may be disposed to face toward the airflow direction.

In one embodiment, the cleat pocket 105 includes a first cleat portion at a top thereof and a second cleat portion at a bottom thereof. Therefore, the drawer can be drawn and pulled through the first buckle part and the second buckle part. The structure of the handle slot 105 can adapt to the operation habits of different people, such as some people are used to pull the drawer upwards, and some people are used to pull the drawer downwards. The first handle part is arranged corresponding to the air guide opening of the handle groove 105, that is, the hand part can extend into the first handle part through the air guide opening; the second handle portion corresponds the air outlet setting of handle groove 105, also can stretch into to second handle portion through the air outlet.

According to the embodiment of the invention, the buckle body 101 and the panel 103 of the drawer are split, so that diversified design of the buckle assembly is facilitated, and different appearance requirements of customers are met.

According to an embodiment of the invention, there is also provided a refrigeration device including the drawer. Wherein, the refrigeration equipment can be a refrigerator, an ice chest and the like.
