[0039] Referring to Figure 1 The present application provides an anti-condensation structure 100 applied to a refrigerator, which is mainly used to prevent condensation from occurring on a turnover beam 10.
[0040] As Figure 1As shown, the anti-condensation structure 100 includes a flip beam 10, a heating assembly 20 and a sensor assembly 30, wherein the flip beam 10 has a length direction x, and a plurality of detection points 11 are arranged at intervals along the length direction x, and the outer surface of the flip beam 10 at the position adjacent to each detection point 11 is a working area 12; the heating assembly 20 includes a plurality of heating units 21, each heating unit 21 adopts a graphene heating film and is fixedly attached to the corresponding working area 12; the sensor assembly 30 includes a plurality of temperature sensors 31, each temperature sensor 31 is arranged at the corresponding detection point, and the signal of the temperature sensor 31 is used to control the heating unit 21 of the adjacent working area 12.
[0041] It needs to be explained that the refrigerator is mainly used for refrigeration or fresh-keeping preservation of food, and the internal temperature is usually lower than the temperature of the external surrounding environment. The cold air in the box body will diffuse to the external environment through the heat insulation layer and the door seal strip, which is easy to cause the condensation phenomenon at the joint of the box body and the door body, i.e. the area where the flip beam is located. Not only will it affect the refrigeration effect of the refrigerator, but also will it absorb dust in the air, which will cause the metal parts on the refrigerator to rust and corrode for a long time, reduce the service life of the refrigerator, and affect the user experience. The existing anti-condensation structure 100 mainly heats the flip beam 10 structure by setting a heating wire to maintain the temperature at the position of the flip beam 10, thereby preventing the condensation phenomenon from occurring. However, the heating process of the heating wire is slow, the heating is uneven, and only the entire flip beam 10 structure can be heated, which consumes a large amount of power, thereby affecting the heating effect and user experience. In the present application, the flip beam 10 is heated by using a graphene heating film, which takes advantage of the high electrical conductivity and good thermal conductivity of graphene to improve the heating rate and heating effect. At the same time, the flip beam 10 structure is divided into a plurality of working areas 12, each working area 12 is provided with a heating unit 21, the graphene heating film is attached to the heating unit 21, and a plurality of detection points 11 are arranged correspondingly. The temperature of each detection point 11 is detected in real time by using the temperature sensor 31. When the signal of the temperature sensor 31 shows that heating is needed, the heating unit 21 of the adjacent working area 12 can be directly controlled to heat. This way of partitioning, real-time detection and temperature control can not only save the overall energy consumption of the anti-condensation structure 100, but also improve the heating effect, thereby improving the user experience.
[0042] For example, the flip beam 10 is a hollow structure and is filled with thermal insulation material, which can effectively improve the heat insulation performance of the position where the flip beam 10 is located.
[0043] Further, along the length direction x, the heating unit 21 only covers a corresponding working area 12 or locally extends to other adjacent working areas 12, so as to improve the real-time rate of temperature control while reducing the heating energy consumption by partitioning detection and temperature control of each heating unit 21, thereby improving the anti-condensation effect of the entire structure.
[0044] For example, the heating units 21 are 2-20, each heating unit 21 is independently controlled, so as to realize the partition detection and heating. The number of heating units 21 can be 2, 6, 9, 13, 20, of course, not limited to this, the specific number of heating units 21 can be determined according to the actual use, in this embodiment, the number of heating units 21 is set to 6.
[0045] As preferred, the anti-condensation structure 100 further comprises a control circuit and a temperature and humidity sensor (not shown), the control circuit can receive the signal from the temperature sensor 31 and compare with the threshold value, and then drive the heating unit 21 according to the comparison result, and the temperature and humidity sensor is used to collect the real-time temperature and humidity signal in the refrigerator, and the corresponding dew point temperature is obtained by the control circuit. Here, the threshold value is a preset value or obtained according to the real-time state in the refrigerator, and the threshold value is related to the dew point temperature.
[0046] For example, the temperature collected by the temperature sensor 31 is t, according to the number of heating units, it can include t1-t7, a total of seven temperature values, of course, not limited to this, the specific number of temperature collected corresponds to the number of heating units 21; the temperature and humidity sensor collects the real-time temperature and humidity at the position of the turnover beam 10, determines the dew point temperature T, T can be compared with t1-t7 respectively, and the threshold value in this embodiment is T+0.5℃.
[0047] When t
[0048] Further, the temperature sensor 31 in the sensor assembly 30 includes an end sensor 311 and a middle sensor 312, wherein the end sensor 311 has only one side adjacent to the heating unit 21, and the middle sensor 312 has both sides adjacent to the heating unit 21. Under the condition that each heating unit 21 can be detected and controlled in time, the specific setting mode can be reasonably set according to the overall structure of the turnover beam 10, and when the signal of the temperature sensor 31 is less than the threshold value, all the adjacent heating units 21 can be started to heat the area where they are located.
[0049] For example, along the length direction x, both sides of each heating unit 21 are adjacent to the temperature sensor 31 and are respectively the first sensor 313 and the second sensor 314, and the control circuit comprises a first comparator, a second comparator and a logic unit, wherein the first comparator respectively receives the threshold value and the signal from the first sensor, and outputs the first judgment signal accordingly; the second comparator respectively receives the threshold value and the signal from the second sensor, and outputs the second judgment signal accordingly; the logic unit respectively receives the first judgment signal and the second judgment signal, and controls the heating unit 21 accordingly.
[0050] That is, when the temperature collected by the first sensor 313 and the second sensor 314 are both above the threshold value, the current heating unit 21 stops heating, otherwise when the temperature collected by any one of the sensors is less than the threshold value, the current heating unit 21 starts heating.
[0051] Here, the logic implementation in the control circuit can be realized by software, and can also be realized by corresponding logic gate circuits due to the limited logic complexity.
[0052] Please continue to refer to Figure 1 The anti-condensation structure 100 is further provided with an electric connection wire 40 for supplying power to the structure.
[0053] The application further provides a refrigerator comprising the anti-condensation structure 100 of the refrigerator turnover beam according to any one of the above embodiments.
[0054] The technical features of the above embodiments can be combined in any manner. In order to make the description concise, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combinations of the technical features do not contradict, they should be considered as the scope of the present application.
[0055] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent protection scope of the present application. It should be pointed out that, for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
