Description

Technical Field

[0001] The utility model relates to the technical field of fresh-keeping cabinets, in particular to a quick-defrosting fresh-keeping cabinet. Background Art

[0002] Rapid defrosting fresh-keeping cabinet is a highly efficient and energy-saving refrigeration equipment. It can quickly reduce the temperature inside the cabinet and keep it constant through advanced refrigeration technology and automatic defrosting function. This kind of fresh-keeping cabinet can not only effectively extend the shelf life of food, but also reduce energy consumption, providing businesses and families with a more convenient and environmentally friendly refrigeration solution.

[0003] The existing patent CN220567567U discloses a fast defrosting fresh-keeping cabinet, including a cabinet, an evaporator installed inside a solid body, a rear self-hanging shutter is arranged at the rear end of the evaporator, and an evaporation fan is installed at the front end of the evaporator, heating pipes are installed on both sides of the evaporator, and the front end of the cabinet is equipped with a self-hanging shutter. By arranging the self-hanging shutter and the rear self-hanging shutter in the air duct, and the evaporation fan and the heating pipe are both located between the self-hanging shutter and the rear self-hanging shutter, when the evaporation fan is running, the self-hanging shutter and the rear self-hanging shutter will be blown open to realize circulating wind, when the evaporation fan stops running, the self-hanging shutter and the rear self-hanging shutter automatically droop and close to form a sealing condition, at this time, the heating pipe can be started to realize defrosting in a sealed state, avoiding heat from entering the refrigeration area along the air duct to affect the use of the device, and when the heat is not leaked, defrosting is faster and more energy-saving.

[0004] This patent solves the problem of automatic defrosting. The above technical solution is achieved by arranging self-hanging blinds and rear self-hanging blinds in the air duct, and the evaporating fan and the heating tube are located between the self-hanging blinds and the rear self-hanging blinds. Therefore, when the evaporating fan is running, the self-hanging blinds and the rear self-hanging blinds will be blown open to achieve circulating air and defrost the refrigerator. However, the above solution still has the problem of low defrosting efficiency. Specifically, the above device only transports hot air into the blinds through the evaporating fan and the heating tube to heat the inside of the safe. This method is not efficient enough in defrosting the safe because the heat distribution may be uneven, resulting in frost in some areas. In addition, if the hot air cannot effectively reach all corners of the safe, the defrosting process may become slow and incomplete. The limitation of this device is that it does not take into account the airflow dynamics and heat exchange efficiency inside the safe, which may result in energy waste and poor defrosting effect. Therefore, the utility model proposes a quick defrosting refrigerator. Utility Model Content

The connecting pipe 811 is responsible for transporting the salt water to the nozzle 812, and finally the salt water is evenly sprayed out through the nozzle 812.

[0030] The above materials only perform defrosting operation on the freezing chamber 4, such as Figure 4 As shown: In the present embodiment, a heating assembly 10 is arranged in the bottom box 1, and the heating assembly 10 includes a water tank 101, a heating plate 102 is arranged at the bottom of the water tank 101, a heating tube 103 is arranged on the heating plate 102, and a hole partition 11 is arranged on the top of the heating assembly 10. Water is poured into the water tank 101, and then the heating tube 103 is used to conduct heat to stimulate the heating plate 102 to heat the water. The generated water vapor is transported to the freezing chamber 2 through the hole partition 11, so as to effectively melt and remove the residual frost.

[0031] Working principle:

[0032] like Figure 1 - Figure 4 As shown:

[0033] During use: Through the dust isolation box 91, the device can effectively isolate dust and tiny particles during operation, ensure that the internal mechanical parts are free from pollution, extend the service life, and keep the operating environment clean. The heating plate 910 inside the salt water tank 98 evenly distributes heat, quickly promotes the melting of salt, and fully integrates with other ingredients to form a uniform and consistent deicing liquid. The fixed plate 93 built into the fixed box 92 provides a solid support structure for the motor 94 and the rotating shaft 96, ensuring that these key mechanical parts remain stable during movement, reducing wear and tear, and improving the reliability and stability of the overall equipment. The motor 94 acts as a power source. Its efficient operation not only drives the fan blades 97 on the rotating shaft 96 to rotate, but also realizes the salt water tank. The effective stirring of salt and liquid in 98 accelerates the dissolution speed and optimizes the mixing effect. The function of the transmission belt 95 is to synchronously drive the rotating shaft 2 96 and the fan blade 97 on the other side to ensure the balanced stirring force on both sides and improve the overall stirring efficiency. The fixed rod 99 stabilizes the salt water tank 98 to prevent tilting due to vibration generated during the stirring process, ensuring the safety and stability of the equipment during use. The combined design of the tooth plate 82 and the rack 83 installed at the bottom of the sliding groove 81 enables the sliding plate 84 to accurately slide at the bottom while achieving precise adjustment of the angle.

The setting of the arc plate 85 is further The flexibility of the nozzle 812 is further increased, so that the nozzle 812 can be adjusted at multiple angles during the sliding process, so as to better adapt to complex usage scenarios. The sliding rod 86 allows the nozzle 812 to move smoothly in the arc plate 85, which enhances the position adjustability of the nozzle 812, so that the spraying range is wider and the coverage area is larger. The gear 89 assembled on the rotating shaft 87 interacts with the sliding plate 84, further ensuring that the nozzle 812 can accurately adjust the spraying angle when sliding, so that it can be more accurately aimed at the target area. The positioning plate 88 ensures that the gear 89 is firmly engaged with the rotating shaft 87 during operation to prevent it from falling off due to high-speed rotation or external force impact, thereby improving the operating reliability of the equipment. The connecting pipe 811 is negative The prepared brine is transported to the nozzle 812, and finally the brine is evenly sprayed out through the nozzle 812 to de-ice the inside of the freezer 2 and the partition 7, and the sliding door 25 is sent into the sliding door 1 4 through the handle 6 so that the brine can be sprayed into the freezer 2 to de-ice the inside of the freezer 2. In addition, after water is filled into the water tank 101, the heating tube 103 starts to work, and the heat is conducted to stimulate the heating plate 2 102 to heat the water. As the water temperature rises, the generated water vapor is transported to the freezer 2 through the porous partition 11. The water vapor quickly heats up in the freezer 2, effectively melting and removing the residual frost, which not only improves the use efficiency of the freezer 2, but also helps to keep the food in the best preservation state.
