Document Type and Number:
WIPO Patent Application WO/2022/143418
Kind Code:
A1
Abstract:
The present invention relates to a hand dryer housing structure, an electric motor vibration damping structure, an air conditioning device and a hand dryer. The hand dryer housing structure comprises a main machine housing (1), wherein the main machine housing (1) has an inner shell (3) and an outer shell (4); the inner shell (3) is accommodated in the outer shell (4), and a gap is provided between same and the outer shell (4); the main machine housing (1) has an air inlet (12) and an air outlet (15); and an electric motor assembly arranged in the inner shell (3) drives external air to enter through the air inlet (12), and to be discharged from the hand dryer through the air outlet (15). The inner shell (3) is accommodated in the outer shell (4), and an air gap layer (16) is provided between the inner shell and the outer shell to enhance the sound insulation effect, so that the noise is effectively reduced, and the user experience is improved. In addition, a sound insulation sponge may be placed in the air gap layer (16). Furthermore, further disclosed is a corresponding hand dryer.
