Design and application of heat insulation handle for quick-frozen freezer
In daily life, we often encounter such a scene: when we open the door of the refrigerator or freezer, our hands will feel uncomfortable because they touch the cold metal handle. Especially in the cold winter or in the case of extremely low refrigeration temperature, this feeling is more obvious. In order to solve this problem and improve the user's experience, designers have developed a new product-the insulated handle of quick-frozen freezer.
I. Design background and principle
With the continuous improvement of people's living standards, the requirements for household appliances are getting higher and higher, which require not only powerful functions and stable performance, but also beautiful appearance and convenient operation. In view of the problem that the traditional metal handle of freezer is easy to cause cold in hands, designers put forward the concept of quick-frozen freezer heat insulation handle.
The handle is made of special material and has good heat insulation effect. When the hand touches the guard, it can effectively isolate the influence of cold air inside the freezer on the hand, and avoid the problems of finger numbness caused by opening the freezer for a long time; At the same time, it can also prevent external heat from transferring inward, which is helpful to maintain the low temperature environment in the freezer. In addition, precision machining technology is also adopted in the production process to ensure the durability and safety of the product.
Second, the material selection and advantage analysis
1. Material characteristics
(1)PP plastic (polypropylene): It has excellent heat resistance, corrosion resistance and impact strength, light weight and low cost;
(2) silica gel: soft and elastic, which can better fit the contour of the user's palm and increase the grip comfort;
(3)EVA foam: low density, good flexibility, good sound-absorbing and sound-insulating properties make it one of the ideal cushioning materials, and can be added to the other two materials as a filler to enhance the overall shock-proof effect.
2. Summary of advantages:
(1) Good hand feeling and warm touch;
(2) Not easy to deform and age;
(3) simple and convenient cleaning and maintenance;
(4) The production process is environment-friendly and pollution-free;
Third, the application scenario expansion
Besides being used in household appliances, the insulated handle of quick-frozen freezer can also be widely used in various commercial occasions such as supermarkets, hotels and other places. Especially for large-scale refrigerated warehouses, workers need to frequently open and close equipment doors for cargo handling. At this time, if a handle with good thermal insulation performance and easy to grasp can be equipped, the work efficiency can be greatly improved and the risk of personal injury can be reduced.
To sum up, the insulated handle of quick-frozen freezer is gradually favored by consumers for its unique advantages, and more innovative technologies and design concepts will be integrated into it in the future to meet the needs of different groups of people.
