Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration equipment, in particular to a door assembly and a refrigerator. Background Art

[0002] With the application of refrigerators in our daily life, refrigerators have not only improved the level of food preservation in the kitchen, but also improved people's quality of life. At the same time, with the development of the economy, the types of items stored in refrigerators are increasing, and people's demand for refrigerator capacity is increasing. At present, large-capacity cross-door refrigerators on the market generally use flip beams to achieve door closing operations. However, when the flip beam is manually opened, it will hit the door body when it flips, which will produce a lot of noise, and the user experience is not good. At present, the market has reduced the noise caused by the impact by adding shock-absorbing blocks, but opening the door with force will still produce a lot of noise, and excessive force will cause the flip beam to hit the door body and turn outward. At this time, the flip beam needs to be manually pulled back, which seriously affects the user experience. Summary of the Invention

[0003] In order to solve the technical problem in the prior art that the refrigerator door body rotates unreliably and affects the user experience, a door body assembly and a refrigerator are provided in which a slide groove is arranged on the flip beam and cooperates with a slider to ensure reliable rotation of the door body.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] like Figures 1 to 3The door assembly shown includes: a fixed plate 1; a flip beam 2, the flip beam 2 is hinged on the fixed plate 1, and a slide groove 21 is provided on the flip beam 2; a first slider 3, the first slider 3 is hinged on the fixed plate 1, and the first slider 3 is slidably provided in the slide groove 21; a driving mechanism, the driving mechanism is provided on the fixed plate 1, and the driving mechanism can drive the flip beam 2 to move. The slide groove 21 is provided on the flip beam 2, and the first slider 3 is used to slide in the slide groove 21 to limit the movement of the flip beam 2, so as to avoid direct collision between the door body and the box body and the generation of large noise. At the same time, the driving mechanism is provided to drive the door body accordingly according to the movement of the door body, so that the flip beam 2 can adapt to the rotation of the door body, so as to avoid collision between the door body and the flip beam 2 and the generation of noise, thereby ensuring the reliable rotation of the door body and improving the user experience.

[0026] To achieve the flipping movement of the flip beam 2, the drive mechanism includes a second slider 41 and a screw 42. The screw 42 is rotatably mounted on the fixed plate 1, and the second slider 41 is movably mounted on the screw 42. The flip beam 2 is hingedly connected to the second slider 41. The rotation of the screw 42 drives the second slider 41 to move along the axis of the screw 42. The first slider 3 restricts the flip beam 2, causing the first slider 3 to slide within the chute 21. The flip beam 2 can also flip under the combined effects of the axial movement of the screw 42 and the squeeze and limit between the chute 21 and the first slider 3.

[0027] The driving mechanism further includes a driving motor 43, which is disposed on the fixing plate 1, and the screw rod 42 is connected to the driving motor 43. The rotation of the driving motor 43 can drive the screw rod 42 to rotate forward or reverse, thereby realizing the flipping or resetting of the flip beam 2.

[0028] The slide groove 21 is in an arc shape, and the opening direction of the arc faces away from the fixed plate 1. By setting the slide groove 21 in an arc shape, the first slider 3 can slide smoothly in the slide groove 21, and the opening direction of the arc shape can ensure that the flip beam 2 flips in the set direction.

[0029] As another embodiment, the sliding groove 21 is V-shaped, and the opening direction of the V-shape faces away from the fixed plate 1. A rounded structure is provided at the top corner of the V-shape, and the straight line segment of the V-shape can increase the rotation speed of the flip beam 2 during the flipping process, thereby improving the opening and closing speed of the door body.

[0030] The cross section of the first sliding block 3 is a bar, one end of the bar is hinged to the fixing plate 1 , and the other end is slidably disposed in the sliding groove 21 .

[0031] like Figure 1 As shown, the shape of the first slider 3 is L-shaped, which can be selected and set according to needs.

[0032] The door assembly also includes a detection mechanism capable of detecting the rotational state of the door, and the detection mechanism is electrically connected to the drive mechanism. When closing the door, the door and the housing interact via a sensing device, driving the motor in reverse rotation. The motor, via gears, rotates the screw, which in turn drives the flip beam 2 to flip outward. When separating the door and housing, the motor rotates in the forward direction, which, via gears, drives the screw, which in turn drives the flip beam 2 to pull back. When the door is open, the flip beam 2 remains in the retracted state, preventing direct collision between the flip beam 2 and the door.

[0033] A refrigerator comprises the above-mentioned door assembly.

[0034] The refrigerator includes a box body and at least two doors. The door bodies are rotatably arranged on the box body. The door body components are arranged on the box body. The door body components correspond to the door bodies one by one.

[0035] All the door bodies are distributed in a cross shape.

[0036] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
