Importance and method of testing freezer handle
In our daily life, freezer is an indispensable household appliance. In the various parts of the freezer, although the handle looks inconspicuous, it is one of the most frequently contacted parts when we use the freezer. Therefore, it is very important to detect the quality of the freezer handle.
First, the function and importance of freezer handle
The first thing to understand is that the freezer handle is not just an ornament designed for beauty. In fact, it is an important tool for us to open or close the freezer door. A handle with good quality can save us more effort in the process of opening and closing, and at the same time reduce the risk of damage to the refrigerator door due to excessive force. In addition, in some special cases (such as wet hands, freezing, etc.), a good handle can provide additional security.
Second, the inspection method of freezer handle
1. Material selection inspection
The freezer handle is usually made of metal or plastic. Due to the difference of these materials, their strength, durability and corrosion resistance are also different. Therefore, when purchasing, we should try to choose products made of high-quality materials, and it is best to judge the quality of the products by observing whether their surfaces are smooth and whether there are obvious scratches.
2. Structural stability evaluation
The evaluation of structural stability is mainly carried out from the following aspects:
(1) feel test: put your hand on the handle and feel how it feels; (2) Shake the handle a few times to see if it is firm; (3) Measurement of opening strength Use professional equipment to accurately measure the required strength of the handle to ensure that users can easily open and close the refrigerator door.
3. Investigation of anti-skid performance
In order to improve the anti-skid effect, many manufacturers will add some concave-convex lines or other anti-skid measures in the design. However, this may bring about problems such as cleaning difficulties, so consumers can judge its actual effect by touching it personally.
4. Durability verification
In addition to the above, we should also pay attention to the following points:
(1) Long-term storage of food will lead to the leakage of cold air, which will affect the normal work of the refrigerator;
(2) Frequent switching will cause some parts to wear and reduce the service life;
(3) The use under harsh environmental conditions also needs special attention.
III. Conclusion
In a word, every detail must be strictly controlled when buying new household appliances, especially for high-frequency equipment such as freezers. Only after careful examination can we ensure that we can buy high-quality goods that really suit us.
