[0031] The cabinet body 13 serves as the main frame of the refrigeration cabinet, and is used for accommodating all components and providing a refrigeration space.

Ventilation holes can be provided on the cabinet body 13 as needed, and pulleys can be provided at the bottom.

[0032] The heat exchange box 1 is arranged in the cabinet body 13, and the bottom is in contact with the copper pipe 3.

The purpose is to ensure that the cold air is heated and uniformly delivered to the glass surface. The air volume is stable, which promotes heat transfer. The heat exchange box 1 is provided with corresponding holes for the wiring of the circulating fan 2, which is not described here.

[0034] The copper pipe 3 is arranged at the bottom of the heat exchange box 1 and connected with the compressor 11 and the radiator 12, which transmits high-temperature and high-pressure refrigerant gas inside. It can heat the air by using the waste heat of the refrigerant without additional heating devices. It achieves the purpose of energy saving and environmental protection and fully utilizes the heat of the system.

[0035] The air return port 4 and the air outlet port 6 are respectively communicated at both ends of the heat exchange box 1, each of which is provided with two, which are respectively connected with the air return pipe 5 and the air outlet pipe 7. It can form an air circulation path and enhance the air flow coverage. The multi-point setting improves the air flow uniformity and adapts to different sizes of glass covers.

[0036] The air return pipe 5 and the air outlet pipe 7 are connected with the air return port 4 and the air outlet port 6, and are provided with the air flow channel 10 for guiding the air flow. It ensures smooth circulation of air between the air flow channel 10 and the heat exchange box 1. The pipeline layout is reasonable, which reduces the air flow resistance.

[0037] The inner layer glass 8 and the outer layer glass 9 constitute the glass cover, and form the air flow channel 10 therebetween. Through the double-layer structure, a sealed channel is formed, which allows heated air to flow through the glass surface to prevent condensation. It has high transparency, and takes into account the display effect and condensation prevention function.

[0038] The air flow channel 10 is located between the inner layer glass 8 and the outer layer glass 9, and is connected with the air return pipe 5 and the air outlet pipe 7 at both ends. It provides a flow path for heated air and directly acts on the glass surface. It helps to heat evenly and has significant condensation prevention effect.

[0039] The compressor 11 and the radiator 12 are installed in the cabinet 13, which constitutes the core components of the refrigeration system and is connected with the copper pipe 3. It provides refrigeration function and delivers high-temperature refrigerant to the copper pipe 3. Other structures refer to the prior art, which is not described here, and is not shown in the figure.

[0040] The heat preservation layer is arranged on the outer wall of the heat exchange box 1, which is used to reduce heat loss. The purpose is to improve the thermal efficiency of the heat exchange box 1 and reduce energy consumption. Further improve the heat preservation effect and reduce energy waste.

[0041] The temperature sensor is installed in the air flow channel 10 and is electrically connected with the controller. When connected, a hole can be opened on the glass, and the temperature sensor is used to monitor the air temperature near the glass surface. It provides real-time temperature data, supports intelligent control, and improves the adaptability of condensation prevention.

[0042] The controller is electrically connected with the temperature sensor, solenoid valve and circulating fan 2, used to adjust air flow and heating state according to temperature data. It realizes intelligent operation, optimizes anti-condensation effect, has high automation degree and convenient operation.

[0043] The solenoid valve is installed on the return air pipe 5 and the outlet air pipe 7, and is electrically connected with the controller, used to adjust the opening and closing and flow of the air flow channel. Its purpose is to accurately control the air flow to adapt to different environmental needs. The advantage is fast response and flexible regulation.

[0044] The damping support is arranged at the installation position of the circulating fan 2 and the heat exchange box 1, used to reduce the vibration and noise during operation. Its purpose is to improve the running stability of the equipment and improve the user experience. The advantage is that the damping effect is remarkable, and the service life of the equipment is prolonged.

[0045] The working principle is as follows: when the refrigerator is running, the compressor 11 compresses the refrigerant into high-temperature and high-pressure gas, which is transmitted to the radiator 12 through the copper pipe 3. Part of the heat of the copper pipe 3 heats the air in the box. The circulating fan 2 drives the air flow, so that the cold air enters the heat exchange box 1 through the return air port 4 and the return air pipe 5, and is heated at the heat exchange box 1. The heated air enters the air flow channel 10 through the outlet air port 6 and the outlet air pipe 7, flows through the surface of the inner glass 8 and the outer glass 9, increases the glass temperature, and prevents condensation. The temperature sensor monitors the air temperature in the air flow channel 10 in real time, and transmits the data to the controller. The controller adjusts the opening of the solenoid valve according to the temperature data to control the air flow, or adjusts the rotating speed of the circulating fan 2 to ensure that the glass surface temperature is higher than the condensation point. The heat insulating layer reduces the heat loss of the heat exchange box 1, and the damping support reduces the running noise, which together ensures the efficient and stable operation of the system.

[0046] Example 2

[0047] This embodiment provides a refrigerator for preventing glass condensation, which is different from example 1 in that an electric telescopic rod 14 is additionally arranged in the cabinet 13. The electric telescopic rod 14 is installed in the cabinet 13, and the output end is fixedly connected with the heat exchange box 1 and is electrically connected with the controller, and can drive the heat exchange box 1 to separate from the copper pipe 3. Its purpose is to stop heating when condensation is not needed, so that the heat of the copper pipe 3 is directly dissipated into the cabinet 13 or other heat dissipation paths, such as the cabinet 13 which can be provided with ventilation and heat dissipation holes according to needs, to avoid unnecessary heating. The advantage is that the energy saving and controllability of the system are improved, and the maintenance and cleaning are facilitated.

[0048] When the refrigerator is running, the compressor 11 compresses the refrigerant into high-temperature and high-pressure gas, which is transmitted to the radiator 12 through the copper pipe 3. When anti-condensation is needed, the electric telescopic rod 14 keeps the heat exchange box 1 in contact with the copper pipe 3, and the heat of the copper pipe 3 heats the air in the heat exchange box 1. The circulating fan 2 drives the air to enter the heat exchange box 1 through the air return port 4 and the air return pipe 5, and after being heated, the air enters the air flow channel 10 through the air outlet 6 and the air outlet pipe 7, flows through the inner glass 8 and the outer glass 9, and increases the glass temperature to prevent condensation. The temperature sensor monitors the temperature in the air flow channel 10, and the controller adjusts the opening degree of the electromagnetic valve and the rotating speed of the circulating fan 2 according to the data to maintain the anti-condensation effect. The heat insulation layer and the damping support respectively ensure the heat efficiency and the operation stability. When anti-condensation is not needed, for example, the ambient humidity is low or the glass temperature is higher than the condensation point, the controller drives the electric telescopic rod 14 to separate the heat exchange box 1 from the copper pipe 3, and the heat of the copper pipe 3 is no longer transmitted to the heat exchange box 1, but is directly dissipated into the cabinet 13 or other heat dissipation paths, and the heating process of the air flow channel 10 is stopped.
