Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, and in particular to a box frame and a refrigerator. Background Art

[0002] A freezer is a household or commercial appliance used to refrigerate or freeze food and items. It usually uses refrigeration technology to keep the temperature at a lower level to keep the food fresh and extend its shelf life.

[0003] A refrigerator generally includes a box body, a door, a refrigeration system, and a control system. The box body of the refrigerator is usually made of a foam material. This material often deforms due to temperature changes during the foaming process and the subsequent refrigeration process, thereby affecting the overall performance and appearance of the refrigerator. In order to prevent the deformation of the foamed box body, the prior art generally adopts a method of presetting a reinforcing iron in the box frame. As a reinforcing structure, the reinforcing iron can effectively resist the deformation of the box body during the foaming and refrigeration process. However, the fixing method of the reinforcing iron has always been a technical problem in the industry. Traditional fixing methods, such as screwing, pasting tape or hot melt adhesive, can fix the reinforcing iron to a certain extent, but there are many shortcomings. For example, although the screwing method is firmly connected, the operation is cumbersome, the efficiency is low, and the foaming layer of the box body may be damaged; although the method of pasting tape or hot melt adhesive is simple to operate, the fixing effect is unstable and it is easy to fall off. Especially in a long-term hot and cold alternating environment, the tape or hot melt adhesive is prone to aging and failure, resulting in the failure of the fixing of the reinforcing iron.

[0004] Therefore, the industry has been seeking a more efficient and reliable way to fix the reinforcement iron to improve the performance and stability of the refrigerator. This patent is proposed in this context, aiming to solve the problems existing in the prior art and promote the advancement of refrigerator technology by using a new box frame and reinforcement iron structure and a snap-on connection method to achieve fast and reliable assembly of the reinforcement iron.

[0017] frame;

[0018] A first plug-in cavity, the first plug-in cavity is arranged on one side of the frame;

[0019] A second plug-in cavity, the second plug-in cavity is arranged on a side of the frame where the first plug-in cavity is arranged; the openings of the first plug-in cavity and the second plug-in cavity are arranged opposite to each other;

[0020] A buckle, the buckle is arranged in the second plug-in cavity;

[0102] In some embodiments, after the two ends of the reinforcing iron 500 are respectively inserted into the first inserting cavity 201 and the second inserting cavity 301 , the reinforcing iron 500 fits with the frame 100 .

[0103] In some embodiments, the cross section of the reinforcing iron 500 is U-shaped.

[0104] In some embodiments, the opening of the first plug-in cavity 201 on the first fixing block 200 is chamfered away from the edge of the frame 100 , and the chamfer makes it easier for the user to insert the reinforcing iron 500 into the first plug-in cavity 201 .

When the reinforcing iron 500 is inserted into the second plug-in cavity 301, the reinforcing iron 500 contacts the clamping block 402, and the elastic plate 401 is bent. When the clamping block 402 moves to the card slot 600, the clamping block 402 is clamped into the card slot 600 under the rebound of the elastic plate 401. The clamping connection between the buckle 400 and the card slot 600 is completed to prevent the reinforcing iron 500 from moving toward the first plug-in cavity 201, causing the reinforcing iron 500 to be separated from the second plug-in cavity 301.

[0114] In some embodiments, a lever 800 is provided on one side of the elastic plate 401 away from the second plug-in cavity 301. During installation, the lever 800 can be manually moved to bend the elastic plate 401, and the clamping block 402 can be away from the frame 100, so that when the reinforcing iron 500 moves to the second plug-in cavity 301, the reinforcing iron 500 needs to push the clamping block 402 with too much force, resulting in the elastic plate 401 being unable to deform. This facilitates installation.

[0118] Please refer to Fig.10 In addition, the present application also provides a refrigerator, which uses the above box frame. The refrigerator includes a box body 900, and one side of the box body 900 is opened.

[0119] In some embodiments, the box frame is disposed at the opening of the box body 900. The box frame on the refrigerator is conveniently and quickly installed with the reinforcing iron 500, and has sufficient structural strength, thereby improving production efficiency.

[0120] In some embodiments, the reinforcing iron 500 is disposed on the side of the frame 100 facing the box body 900. The reinforcing iron 500 is hidden between the frame 100 and the box body 900, and the reinforcing iron 500 is not visible from the appearance, thereby improving the aesthetics.

[0121] In some embodiments, the refrigerator may include a refrigeration system that supplies cold air to the interior of the cabinet 900 .

[0122] In some embodiments, the refrigeration system may include a compressor.

[0123] In some embodiments, the refrigeration system may include a condenser.

[0124] In some embodiments, the refrigeration system may include a throttling device.

[0125] The working process of the refrigeration system may include a compression process.

[0126] The compression process is as follows: the compressor starts working, low-temperature, low-pressure refrigerant is sucked into the compressor, compressed into high-temperature, high-pressure superheated gas in the compressor cylinder, and then discharged into the condenser.

[0127] The working process of the refrigeration system may include a condensation process.

[0128] The condensation process is as follows: the high-temperature, high-pressure refrigerant gas dissipates heat through the condenser, the temperature continues to drop, and it is gradually cooled to a saturated vapor at room temperature and high pressure, and further cooled to a saturated liquid. The temperature no longer drops. The temperature at this time is called the condensation temperature. The pressure of the refrigerant remains almost unchanged during the entire condensation process.

[0129] The working process of the refrigeration system may include a throttling process.

[0130] The throttling process is as follows: the condensed refrigerant saturated liquid passes through a drying filter to remove moisture and impurities and then flows into the throttling device, through which throttling and pressure reduction are performed, and the refrigerant becomes wet steam at room temperature and low pressure.

[0131] The working process of the refrigeration system may include an evaporation process.

[0132] The evaporation process is as follows: wet steam at room temperature and low pressure begins to absorb heat and vaporize in the evaporator, which not only reduces the temperature of the evaporator and its surroundings, but also turns the refrigerant into a low-temperature, low-pressure gas. The refrigerant coming out of the evaporator passes through the gas-liquid separator and returns to the compressor again, repeating the above process to transfer the heat in the freezer to the air outside the freezer, thus achieving the purpose of refrigeration.

[0133] In the present application, a compressor cavity may be formed in the box body 900. The compressor is disposed in the compressor cavity.

[0134] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
