Description

Technical Field

[0001] This utility model relates to the field of hand dryer technology, specifically to a hand dryer installation structure that is easy to assemble and store. Background Technology

[0002] Hand dryers generally fall into two main categories: heated and high-speed air drying. Each type has its own characteristics. Heated hand dryers typically have a high heating power, exceeding 1000W, while the motor power is very low, less than 200W. A key feature of this type is the high air temperature, which removes water from the hands. This method dries hands relatively slowly, generally taking over 30 seconds. High-speed air dryers, on the other hand, feature extremely high air speeds, reaching over 130 meters per second. They dry hands in about 10 seconds, with a lower heating power of only a few hundred watts. The heating function is primarily for comfort and does not significantly affect the drying speed. These are commonly used in office buildings and public spaces, and are typically wall-mounted.

[0003] Chinese patent document CN215937184U discloses a hand dryer. In this invention, the hand dryer has a housing with an air outlet. An air duct leading to the air outlet is formed within the housing. The housing also houses at least one circuit board, a motor electrically connected to the at least one circuit board, and fan blades driven by the motor. The circuit board is arranged within the air duct, dividing the air duct into at least two sub-air ducts, each extending along the direction of the air duct and communicating with the air outlet. At least one circuit board has a guide element located within a sub-air duct and separated from the housing. The guide element also covers at least a portion of the electronic components on its circuit board. Compared to existing technologies, this hand dryer has a simple internal installation structure and fewer wiring harnesses.

[0004] The existing hand dryers do not have a power cord storage structure, resulting in a messy and unsightly power cord. In addition, the installation and removal of the HEPA filter is cumbersome, requiring the shell to be opened and the screws to be removed or special tools to be used for disassembly. Therefore, there is a need to develop a hand dryer installation structure that is easy to assemble and store. Utility Model Content
