Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of refrigeration equipment, and specifically relates to a refrigeration cabinet with good refrigeration effect. BACKGROUND

[0002] The refrigeration cabinet is a device for refrigerating and preserving food, medicine and other articles, and is widely applied to supermarkets, convenience stores, hotels and other places. The core function thereof is to keep articles fresh through constant temperature and strong freezing power and air purification technology, adopts a back-blow refrigeration system, high-efficiency evaporator and precise temperature control technology to ensure that the internal temperature is uniform (generally, the temperature in the refrigeration chamber is 0-5 DEG C, and the temperature in the freezing chamber can reach below-18 DEG C), and has energy-saving characteristics such as night energy-saving curtain, natural air defrosting and low energy consumption design.

[0003] At present, the refrigeration cabinet generally adopts a design of injecting cold air from the top, and cold air is blown downward by an evaporator or a fan to cover the entire refrigeration space. This design can effectively maintain temperature uniformity and stability when the number of trays is small. However, when a large number of trays are stacked in the cabinet, the cold air distribution will have obvious defects: if the cold air outlet is directly opposite the upper part of the tray, the cold air will blow directly on the upper tray, resulting in too low temperature in the upper region, and the cold air is difficult to sink fully due to flow obstruction, causing the temperature of the lower tray to be too high; if the cold air outlet is not aligned with the tray, the cold air will naturally sink due to its large specific gravity, and excessively gather in the bottom region to form a low-temperature zone, while the upper part is relatively high in temperature due to insufficient circulation of the cold air, finally resulting in obvious cold and hot stratification in the refrigeration space, affecting temperature uniformity. SUMMARY

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please refer to Figures 1-8 ;

[0027] A refrigerator with good refrigeration effect includes a cabinet body 1. Symmetrical connectors 2 are provided on both sides of the front end of the cabinet body 1. Each side has two connectors 2 that rotate to connect to a cabinet door 3, forming a double-door structure that can be opened and closed. A refrigeration unit 4 is provided at the top of the cabinet body 1 to deliver cold air from the top into the cabinet. The refrigeration unit 4 is a commonly used refrigeration unit in existing refrigerators, which will not be described in detail here. Several support assemblies 5 are symmetrically arranged inside the cabinet body 1. The support assemblies 5 support trays 6 for placing refrigerated items. An airflow zone 7 for downward flow of cold air is provided between two support assemblies 5. Due to the high density of cold air, the cold air generated by the refrigeration unit 4 enters the airflow zone 7. The air will naturally sink, causing the temperature at the bottom of cabinet 1 to drop first. The cold air exchanges heat with the items at the bottom, heating up to form hot air that flows upwards. Because the cold air cannot be replenished to the top area in time, this results in an uneven temperature distribution inside the cabinet, with the upper layer being warmer than the lower layer. To address this, a rotary motor 71 is installed at the center of the bottom of the airflow zone 7. A support column 72 is mounted on the rotary motor 71. A rotating seat 74, rotatably connected to the other end of the support column 72, is installed inside cabinet 1. Several arc-shaped air guide plates 73 are provided on the outer edge of the support column 72. The air guide plates 73 are made of lightweight plastic and have a streamlined arc-shaped surface design. During operation, the rotary motor 71 drives the support column 72 and air guide plates 73 to rotate slowly at a low speed. Through the guiding action of the air guide plates 73, some of the falling cold air is first directed to the upper side trays 6, ensuring the cooling effect on the upper items. At the same time, the slow rotation of the air guide plates 73 ensures that the bottom area still receives a continuous supply of cold air, thus achieving a balanced temperature inside the cabinet. In addition, several arc-shaped air guide plates 73 are provided with several through holes 75 in the vertical direction. The through holes 75 can effectively reduce the wind resistance of the air guide plates 73, thereby reducing the operating energy consumption of the rotary motor 71.

[0028] In this embodiment, a temperature sensor 8 is installed inside the cabinet 1. The temperature sensor 8 is located above the top tray 6. When the temperature sensor 8 detects that the temperature inside the cabinet has reached the set low temperature threshold, it will transmit a signal to the control system (not shown in the figure). The control system will control the rotary motor 71 to stop running to avoid energy waste.

[0029] In this embodiment, each of the bracket components 5 includes symmetrically arranged L-shaped support frames 51. Each tray 6 is supported by two L-shaped support frames 51 on both sides. The outer side of the L-shaped support frame 51 is provided with a U-shaped bend 52. The cabinet 1 is provided with a number of plug-in parts 11 for inserting the U-shaped bend 52 downwards, so as to realize the quick fixing and disassembly of the L-shaped support frame 51.

[0030] In this embodiment, the two L-shaped support frames 51 used to support a tray 6 are connected by an X-shaped base frame 53 to prevent the tray 6 from bending and deforming due to lack of central support, which could cause it to fall. An anti-slip pad 54 is attached to the center of the X-shaped base frame 53 to improve the stability of the tray 6 when it is placed.

[0031] In this embodiment, the L-shaped support frame 51 has a horizontal plate 55 at the top, and a movable hole 56 on the horizontal plate 55. A limiting block 57 is movably connected inside the movable hole 56. The limiting block 57 is symmetrically provided with an extension 58 above the movable hole 56 to prevent it from coming out of the movable hole 56. The bottom of the limiting block 57 is provided with guide slopes 59 on both sides. The inner sidewall of the limiting block 57 is located inside the L-shaped support frame 51. When the tray 6 is pushed into the L-shaped support frame 51, the outer edge of the tray 6 will press the limiting block 57 upward along the guide slope 59. When the tray 6 is pushed to the position where the limiting block 57 corresponds to the storage space of the tray 6, the limiting block 57 resets under the action of gravity, and its bottom extends into the storage space of the tray 6 to form a physical limit to prevent the tray 6 from accidentally sliding out or falling. When taking out the tray 6, simply pull the tray 6 out directly.

[0032] In this embodiment, the connector 2 includes a fixing frame 21, on which a rotating hole 22 is provided. A rotating shaft 23 is rotatably connected in the rotating hole 22. The other end of the rotating shaft 23 is rotatably connected to the cabinet door 3 to realize the rotating opening and closing function of the cabinet door 3. To prevent the rotating shaft 23 from accidentally coming off, a limiting ring 24 is provided outside the rotating shaft 23. The limiting ring 24 is located between the connector 2 and the cabinet door 3 to ensure that the rotating shaft 23 cannot come off axially.

[0033] In this embodiment, a reset torsion spring 25 is provided on the upper rotating shaft 23. One end of the reset torsion spring 25 is fixedly connected to the fixing frame 21, and the other end is fixedly connected to the limiting ring 24. When the cabinet door 3 is opened, the reset torsion spring 25 generates torsional deformation and stores elastic potential energy. When the cabinet door 3 is released, the reset torsion spring 25 releases energy to drive the rotating shaft 23 to rotate in the opposite direction, thereby causing the cabinet door 3 to automatically close to the initial position, avoiding the problem of cold air leakage caused by forgetting to close the cabinet door 3.
