Description

Technical Field

[0001] The utility model relates to the technical field of refrigerators, in particular to a horizontal refrigerator movable door and a horizontal refrigerator containing the movable door. Background Art

[0002] As a relatively special type of refrigerator, horizontal refrigerators have their own unique characteristics and advantages, and their popularity is gradually increasing.

[0003] At present, the doors of horizontal refrigerators usually adopt a rotating shaft to open and close, and for products that are more difficult to open, a gas spring is added to cooperate with the switch. However, this type of door has the following main shortcomings in practical application: (1) It is difficult to lift the door upward when it is closed, and when the user unfortunately presses his hand, it will cause obvious mechanical damage; (2) The door itself does not have the function of storing and retrieving items. After opening the door, it is still necessary to search deep inside the refrigerator body for the required items, which is time-consuming and laborious. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a horizontal refrigerator movable door and a horizontal refrigerator containing the movable door, which realizes that when the user presses his hand, the door body can be lifted by external force, and at the same time, a storage container is installed at the bottom of the door body to realize direct storage and retrieval of items after the door is opened by designing a non-fixed limited movable connection between the lifting component and the door body.

[0005] The utility model adopts the following technical solutions to solve the above technical problems:

[0035] Example 1

[0036] See also Figure 1-6 A horizontal refrigerator movable door of this embodiment includes a door body 1, a lifting assembly 2, and a storage container 3. The door body 1 is matched on the top of the refrigerator body 4. There are two groups of lifting components 2, which are arranged on the left and right sides of the bottom of the door body 1 respectively; each group of lifting components 2 includes an electric cylinder 21, a servo motor 22, and a clamping plate 23; the electric cylinder 21 is installed on the support seat 41 of the box body 4, the input end of the electric cylinder 21 is connected to the servo motor 22, and the output end is connected to the clamping plate 23 for limiting movement, and the clamping plate 23 is connected to the door body 1 in a floating manner; driven by the servo motor 22, the electric cylinder 21 drives the door body 1 to rise and fall relative to the box body 4; at the same time, under the action of external force, the door body 1 can drive the clamping plate 23 to lift upward to separate from the box body 2 and the electric cylinder 21; a guide shaft 24 is also provided at the bottom of the clamping plate 23, one end of the guide shaft 24 is interference-connected with the clamping plate 23, and the other end thereof extends downward and is positioned and matched with the support seat 41 of the box body 4 through a linear bearing 25, which is used to guide the door body 1 during the lifting and lowering process. The storage container 3 is installed between the two groups of lifting components 2 at the bottom of the door body 1 through fasteners for storing items.

[0037] In this embodiment, the lifting assembly 2 and the door body 1 are designed to be a non-fixed limited movable connection, so that when the user presses his hand, the door body 1 can be lifted by an external force. At the same time, a storage container 3 is installed at the bottom of the door body 1 to realize direct storage and retrieval of items after opening the door.

[0038] Furthermore, in this embodiment, the clamping plate 23 of the lifting assembly 2 is connected to the door body 1 in a floating manner through the movable block 231; specifically, the movable block 231 is installed at the corresponding position of the clamping plate 23 through the elastic pad 232, and screw holes are provided on the movable block 231, and the movable block 231 is fixed to the door body 1 through the screw holes and bolts. The design of the floating connection method is mainly to absorb the cold and hot deformation of the foamed door body 1 through the elastic pad 232 to improve the service life.

[0039] Furthermore, in this embodiment, the clamping plate 23 is provided with a limit installation hole 233 whose longitudinal section is in the shape of a "convex" step, and the guide rod 211 at the output end of the electric cylinder 21 is provided with a limit installation shaft 212 corresponding to the limit installation hole 233; the guide rod 211 and the clamping plate 23 are connected by the limit cooperation between the limit installation hole 233 and the limit installation shaft 212. Based on the above structure, when the servo motor 22 drives the guide rod 211 of the electric cylinder 21 to move upward, the output end of the electric cylinder 21 lifts the door body 1 and moves upward relative to the box body 4; when the servo motor 22 drives the guide rod 211 of the electric cylinder 21 to reset downward, the guide rod 211 of the electric cylinder 21 is reset first, and then the clamping plate 23 moves down naturally by the deadweight of the door body 1 and the storage container 3; at the same time, it can also be realized that when the hand is pressed, the door body 1 can be lifted upward by an external force, and after the power is off, the door body 1 can be lifted up to quickly take out the sample.

[0040] Furthermore, in this embodiment, the servo motors 22 of the two lifting components 2 are respectively connected to the PLC controller, which controls the two lifting components 2 to synchronously drive the door body 1 to rise and fall, thereby controlling the specific position of the door body 1, making it convenient for users to open the door and access items intelligently.

[0041] At the same time, the position locking of the door body 1 after movement is achieved by first braking and positioning the servo motor 22 of the lifting assembly 2 and then reducing the motor potential energy, so as to avoid the movement of the movable door position after directly removing the potential energy (the braking of the servo motor 22 has a reaction time of about 10ms) and the influence of mechanical clearance.

[0042] A position sensor is also fixed on the electric cylinder 21 of the lifting assembly 2, and the position calibration of the door body 1 is facilitated by the sensor at the pole position of the electric cylinder 21. In addition, each time the door body 1 is closed, the position is returned to a circle to eliminate possible cumulative errors.

[0044] Furthermore, in this embodiment, a VIP plate is provided at the top of the door shell of the door body 1, and a plurality of reinforcing plates 12 are arranged transversely along the inner cavity of the door shell. The VIP plate has a heat preservation effect on one hand, and can isolate the outer sheet metal door shell of the door body 1 from the inner foam layer on the other hand, thereby reducing the sheet metal deformation caused by the freezing shrinkage of the foam material; the reinforcing plate 12 can avoid freezing warping.

[0045] In addition, it should be noted that in order to improve the user experience, the storage container 3 of this embodiment can also be designed as a multi-layer storage drawer-type freezing rack, which is convenient for combining with the intelligent lifting component 2 to accurately open the door body 1 to the target position required by the customer, so as to accurately store and retrieve items.
