Practicality and design of anti-coagulation handle for freezer

With the development of science and technology and the improvement of people's living standards, household appliances have become more and more diversified and intelligent. Among many household appliances, the freezer is one of the necessary appliances for every family. However, in the process of use, have you ever encountered the problem of frosting the door handle of the freezer? This will not only affect the convenience of use, but also affect the internal temperature of the freezer and the freshness of food. Therefore, it is very necessary to design a reasonable anti-icing handle.

The design concept of anti-icing handle is mainly to reduce the chance of cold and hot air exchange by changing the material or structure of the handle, so as to achieve the anti-icing effect. A common method is to cover the handle with a special material to isolate the heat from the external environment and keep the temperature in the handle in a relatively stable state. Another method is to make the handle into a hollow structure and fill it with some thermal insulation materials, such as foamed plastic. In addition, some manufacturers have a small heater in the handle, which automatically starts the heating device when the temperature is lower than a certain threshold to prevent the handle from freezing.

At present, the common anti-icing handles on the market are mainly divided into the following categories:

1. Vacuum heat insulation handle: Its principle is to add vacuum layer on the basis of metal material for heat insulation treatment. This can not only ensure the strength, but also effectively prevent the heat from entering the external environment and avoid frosting on the surface of the handle;

2. Composite handle: it is made of composite materials, and its main components include non-metallic substances such as glass fiber and polyester resin. This material has good cold resistance and low thermal conductivity, is not easily deformed by the change of external temperature difference, and maintains a comfortable feel for a long time;

3. Constant-temperature heating handle: A constant-temperature heating plate is embedded in the metal frame and equipped with an electronic controller. When the external temperature is detected to be lower than the set threshold, the heating system will be automatically started, so as to keep the temperature of the handle skin always within the range that the human body feels more suitable, thus achieving the purpose of anti-frosting.

In addition to the above types, there are some innovative design concepts worth learning. For example, using the principle of mercury reflection to make a transparent protective cover, or using nanotechnology to develop new polymer film materials. In short, as long as there is enough imagination and technical support, there will be more and more novel and practical products to make our life more convenient and beautiful.

For consumers, when buying a freezer, they should pay attention to the performance index of the product, especially whether it will be inconvenient to switch because of frosting after long-term operation. If a large number of items need to be stored in cold storage are often stored at home, it is particularly important to choose a freezer handle with good anti-coagulation function. Only in this way can we ensure fresh and delicious food, reduce energy consumption and improve the overall quality of life.
