Description

Technical Field

[0001] The utility model relates to the field of freezing and refrigerating equipment, in particular to a refrigerator without a fixed central column structure. Background Art

[0002] A freezer is a device used to store and display refrigerated food and beverages, mainly to maintain the freshness and taste of these items. Unlike household refrigerators, commercial freezers focus on long-term storage of large quantities of food and beverages, with higher refrigeration capacity and larger storage space. Therefore, freezers are usually widely used in commercial scenarios such as shops, supermarkets, restaurants, and hotels.

[0003] Commercial kitchen freezers currently sold and used on the market need to be designed with a support structure in the middle of the opening of the freezer due to size and structural limitations, namely a vertical beam (also called a fixed center column), so that when the door is closed, the support structure can cooperate with the door seal on the door to achieve a seal. However, when the freezer is in the open state, the vertical beam is located in the middle of the opening, which will hinder the placement of larger items into the freezer.

[0004] Therefore, a method or device capable of solving the above problems is now needed. Summary of the invention

[0005] The utility model aims to solve the above-mentioned deficiencies in the prior art and proposes a refrigerator without a fixed central column structure which has a simple structure, ingenious design, and reasonable layout, and can not affect the sealing effect when closed, does not occupy space when opened, and can allow larger items to pass through.

[0006] The technical solution of the utility model is: a refrigerator without a fixed central column structure, comprising a cabinet body 1, on which a first cabinet door 2 and a second cabinet door 3 are symmetrically arranged, characterized in that: a longitudinally distributed movable column 4 is arranged at the movable side edge of the first cabinet door 2, one side edge of the movable column 4 is rotatably connected to the first cabinet door 2, a guide seat 5 is arranged on the top surface of the movable column 4, an arc-shaped guide groove 6 is opened on the top surface of the guide seat 5, and the entrance of the arc-shaped guide groove 6 is trumpet-shaped, and an movable column driving block 7 matching the arc-shaped guide groove 6 is arranged at the bottom of the top edge of the cabinet body 1,

[0007] The first cabinet door 2 and the second cabinet door 3 are both composed of a door panel 8 and a door lining 9. Door seals 10 are arranged at the edges of the first cabinet door 2 and the second cabinet door 3. The door seals 10 are provided with burrs 11. A sealing curtain 12 is also arranged at the bottom of the movable column 4.

[0008] A limiting block 13 is arranged on the bottom end surface of the movable middle column 4. Under the restriction of the limiting block 13, the maximum swing angle of the movable column 4 is 90°.

[0009] Compared with the prior art, the utility model has the following advantages:

[0010] The refrigerator without a fixed center column structure of this structural form has a simple structure, ingenious design and reasonable layout. In view of the various problems caused by the need to set a fixed center column structure in the middle of the opening of the traditional refrigerator, a special movable center column structure is designed, in which the center column structure is directly set on a cabinet door, and the center column structure can swing relative to the cabinet door. A guide seat with an arc guide groove is set at the top of the center column structure, and a movable column driving block matching the arc guide groove is set at the opening of the cabinet. Under the action of the movable column driving block, the movable column will swing along the trajectory of the arc guide groove, from a state perpendicular to the cabinet door to a state parallel to the cabinet door. That is to say, when the two cabinet doors are closed, the movable column is located at the center of the cabinet opening and can fit with the edges of the two cabinet doors to ensure the sealing effect; and when the cabinet doors are opened, there is no structural obstruction inside the cabinet opening, so relatively large items can be placed inside the cabinet.

[0011] This type of refrigerator without a fixed center column structure has a simple manufacturing process and low manufacturing cost. Therefore, it can be said that it has multiple advantages and is particularly suitable for promotion and application in this field. Its market prospect is very broad.

[0017] The specific implementation of the present utility model will be described below in conjunction with the accompanying drawings. Figures 1 to 5As shown: a refrigerator without a fixed center column structure, comprising a cabinet body 1, on which a first cabinet door 2 and a second cabinet door 3 are symmetrically arranged, a longitudinally distributed movable column 4 is arranged at the movable side of the first cabinet door 2, one side of the movable column 4 is rotatably connected to the first cabinet door 2, a guide seat 5 is arranged on the top surface of the movable column 4, an arc-shaped guide groove 6 is opened on the top surface of the guide seat 5, and the entrance of the arc-shaped guide groove 6 is trumpet-shaped, and a movable column driving block 7 matching the arc-shaped guide groove 6 is arranged at the bottom of the top edge of the cabinet body 1,

[0018] The first cabinet door 2 and the second cabinet door 3 are both composed of a door panel 8 and a door lining 9. Door seals 10 are arranged at the edges of the first cabinet door 2 and the second cabinet door 3. The door seals 10 are provided with burrs 11. A sealing curtain 12 is also arranged at the bottom of the movable column 4.

[0019] A limiting block 13 is arranged on the bottom end surface of the movable middle column 4. Under the restriction of the limiting block 13, the maximum swing angle of the movable column 4 is 90°.

[0020] The working process of the refrigerator without a fixed center column structure of the embodiment of the utility model is as follows: when the first cabinet door 2 and the second cabinet door 3 are both in the open state, since the movable column 4 is connected to the first cabinet door 2, there is no blocking structure at the opening of the cabinet body 1, so relatively large items can be put into the interior of the cabinet body 1 through the opening; at this time, the plane where the movable column 4 is located is perpendicular to the plane where the first cabinet door 2 is located;

[0021] When the first cabinet door 2 is closed, the movable column 4 moves toward the direction of the cabinet body 1 with the closing action of the first cabinet door 2. When the guide seat 5 on the top surface of the movable column 4 moves to the movable column driving block 7, the movable column driving block 7 will enter the arc guide groove 6 along the trumpet-shaped entrance of the arc guide groove 6. With the movement of the guide seat 5, the movable column driving block 7 moves relatively in the arc guide groove 6. During the relative movement of the two, the guide seat 5 will drive the movable column 4 to swing under the action of the movable column driving block 7. After the movable column 4 rotates 90°, it changes from a state perpendicular to the first cabinet door 2 to a state coplanar with it. At this time, a part of the movable column 4 contacts with the first cabinet door 2, and the other part contacts with the edge of the second cabinet door 3 in the closed state. The door seals 10 arranged at the edges of the two cabinet doors will contact with the end face of the movable column 4.

[0022] Since the door seal 10 is provided with a burr 11, the burr 11 can expand the sealing area and ensure the sealing effect, and the sealing curtain 12 arranged at the bottom of the movable middle column 4 will close the gap between the bottom of the movable middle column 4 and the two cabinet doors. This movable column structure can effectively ensure the sealing effect and prevent cold leakage when the cabinet door is closed. When the cabinet door is opened, there is no fixed blocking structure inside the opening of the cabinet body 1, so larger objects can be easily placed in the cabinet body 1.
