Description

Technical Field

[0001] The utility model relates to the technical field of refrigerators, in particular to a refrigerator capable of preventing condensation on the surface of a door. Background Art

[0002] As people's requirements for refrigerator volume utilization continue to increase, refrigerators are becoming thinner and thinner. As the refrigerator body becomes thinner, the refrigerator door is also getting thinner. During the plum rain season, the air humidity is high and the dew point temperature is high. In the absence of significant improvement in the current foaming technology, the insulation capacity of the thin refrigerator door is weakened, especially for refrigerators with glass doors. In environments with high humidity such as the plum rain season, condensation is particularly easy to form on the surface of the refrigerator door.

[0003] Once condensation occurs on the surface of the refrigerator door, it will not only be unsightly, but also inconvenient to use. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 As shown, the utility model discloses a refrigerator capable of preventing condensation on the door surface, comprising a refrigerator body, a refrigerator door body being arranged on the front side of the refrigerator body, the refrigerator door body being composed of an upper refrigerator door 6 and a lower refrigerator door 7 distributed up and down, and both the upper refrigerator door 6 and the lower refrigerator door 7 are double-doors.

[0022] See also Figure 2 A refrigerator top cover 5 is arranged on the top of the refrigerator body, and a concealable fan duct 1 is installed on the edge side of the refrigerator top cover 5 close to the refrigerator upper door 6, that is, the front side. The front end of the concealable fan duct 1 is retractable. When the concealable fan duct 1 is extended, the air outlet thereof faces the surface of the refrigerator upper door 6. A fan is arranged inside the concealable fan duct 1 to achieve an air outlet effect, thereby blowing air to the environment on the surface of the refrigerator upper door 6.

[0023] See also Figure 3 A temperature and humidity sensor 3 is installed on the top of one of the doors of the refrigerator upper door 6, and the temperature and humidity sensor 3 can sense the humidity of the environment. A refrigerator top beam 8 is arranged on the front top of the refrigerator body, and a human body sensor 4 is installed at the center of the refrigerator top beam 8. The human body sensor 4 is just located between the two doors of the refrigerator upper door 6. When the human body approaches the refrigerator body, the refrigerator upper door 6 can be sensed; a computer board 2 is installed on the top of the refrigerator body, and the computer board 2 is connected to the concealable fan duct 1, the temperature and humidity sensor 3 and the human body sensor 4 respectively through wires to achieve communication connection.

[0024] It should be noted that the concealable fan duct 1, the temperature and humidity sensor 3 and the human body sensor 4 are all conventional electrical components in the prior art and can be directly purchased and used, so their specific structures are not described in detail.

[0025] The working principle of the utility model is:

[0026] A humidity threshold is set for the temperature and humidity sensor 3. When the ambient humidity is greater than the humidity threshold, condensation will occur on the surface of the refrigerator door, otherwise it will not. Based on this, when the temperature and humidity sensor 3 senses that the ambient humidity is greater than the set threshold, the concealed fan duct 1 sends a signal to the computer board 2. After receiving the signal, the computer board 2 commands the concealed fan duct 1 to open, so that the concealed fan duct 1 extends to the top of the refrigerator door and exhausts air through the internal fan, forming an air curtain on the surface of the refrigerator door, accelerating the air circulation near the surface of the refrigerator door, and avoiding condensation of water vapor on the surface of the refrigerator door when the humidity is high; when the temperature and humidity sensor 3 senses that the ambient humidity is less than the set threshold, the concealed fan duct 1 sends a signal to the computer board 2, and the computer board 2 receives the signal. After receiving the signal, the concealable fan duct 1 is commanded to close, so that the concealable fan duct 1 is retracted and the internal fan stops rotating, thereby stopping the air discharge; in the process where the temperature and humidity sensor 3 senses that the ambient humidity is greater than the set threshold, when the human body sensor 4 senses that the human body is close to the refrigerator body, the human body sensor 4 sends a signal to the computer board 2, and the computer board 2 receives the signal and commands the concealable fan duct 1 to close, so that the concealable fan duct 1 is retracted and stops discharging air; when the human body sensor 4 senses that the human body is away from the refrigerator body, the human body sensor 4 sends a signal to the computer board 2, and the computer board 2 receives the signal and commands the concealable fan duct 1 to open, so that the concealable fan duct 1 extends to the top of the refrigerator door and discharges air, thus completing a working cycle.
