Hair dryer

Abstract

Provided is a hair dryer. The hair dryer comprises a wind cylinder and a handle connected to the air cylinder, and the inside of the wind cylinder is provided with a member for generating an air flow;the wind cylinder includes a body and a motor disposed in the body, a through first air outlet passage is arranged on the center of the body, the first air outlet passage is provided with a circularsecond air outlet passage extending to the inside of the body, at least one air inlet passage and the first air outlet passage are obliquely arranged, the air inlet passage communicated with the second air outlet passage is disposed inside the body, and an electric motor is disposed in the air inlet passage. The hair dryer has the advantages that the through first air outlet passage is arranged onthe center of the wind cylinder, appearance is novel, the air inlet passage and the second air outlet passage are arranged obliquely, the air flow does not lose potential energy during the flow aftermany turns, and simultaneously the potential energy is converted into heat energy and high frequency vibration.

Description

technical field [0001] The invention relates to the field of daily household appliances, in particular to a hair dryer. Background technique [0002] The traditional hair dryer only has one air duct, and the air in the rear is directly connected to the air in the front. Since the required air volume is collected by the impeller, the design of the impeller is relatively large, resulting in high noise, and the required air volume is passed through a wind Flow in the channel, and the speed is very fast when passing through the heating coil. The required heating wire group is high power to obtain hot air. The thermal efficiency is poor and the energy consumption is high. [0003] Dyson proposed a brand-new hair dryer structure, by setting the motor at the handle, and setting a hollow air cylinder in the middle, and setting slits and Coanda planes on the air cylinder to discharge the air, but Dyson The air duct of the hair dryer is approximately Z-shaped, with two nearly right-a...

[0002] The traditional hair dryer only has one air duct, and the air in the rear is directly connected to the air in the front. Since the required air volume is collected by the impeller, the design of the impeller is relatively large, resulting in high noise, and the required air volume is passed through a wind flow, and the speed is very fast when passing through the heating wire coil, the required heating wire group is high power, in order to obtain hot air, the thermal efficiency is poor, and the energy consumption is high

[0003] Dyson proposed a brand-new hair dryer structure, by setting the motor at the handle, and setting a hollow air cylinder in the middle, and setting slits and Coanda planes on the air cylinder to discharge the air, but Dyson The air duct of the hair dryer is approximately Z-shaped, with two nearly right-angled turnings in the middle. This air duct structure will directly cause a large part of the wind potential energy to be lost, which will be converted into heat energy and high-frequency vibration.
