Description

Hand-held electric hair drier with side air inlet

Technical Field

The present invention relates to the field of hand-held household appliances, in particular to a side-inlet hand-held hair dryer for hair care and hair drying appliances such as hair dryers and heat-setting brushes.

Background

Based on the characteristic that the hair dryer can be rapidly shaped and dried, the hair dryer has a large audience group. The fan unit in the blower can suck air flow from an air inlet of the blower and send the sucked air flow out from an air outlet opposite to the air inlet, so that the drying purpose is achieved. Additionally, hot air blowers (such as heat styling brushes) are used to style hair in either a wet or dry condition. The air outlet of the blower can be connected with an air nozzle, the air speed of the air flow can be improved through the air nozzle, the air flow can be concentrated, and the purpose of modeling is achieved.

The most important performance for a hair dryer is comfort and safety, and it is generally difficult to compromise both with current hair dryers. Particularly, for the travelling comfort, the most direct problem is the time of hair drying, for the great women of hair volume, often dry the hair and need the time of ten minutes to still need swing, the removal hair-dryer that must not stop blow-dry in-process, waste time and energy, lead to the arm hard, influence and use experience. There are no two ways to dry hair quickly, either to raise the temperature or to increase the air volume. The first approach, commonly used by conventional hair dryers, is to increase the temperature to shorten the time required to dry the hair. But high temperatures are prone to safety issues: the hair is baked to be dry, scales and branches are generated, and the scalp is damaged at high temperature. The second way is to increase the air volume only by increasing the motor to drive a larger fan, but the weight and noise of the hair dryer are increased, and the experience is more affected.

Chinese patent CN201131424Y discloses a side-inlet air blower, which includes a casing, an air inlet is provided on the casing, a fan blade is blown from the air inlet, the air inlet is provided on both sides of the casing, after the motor is started, the air enters from the air inlets on both sides simultaneously, the air volume is large, the motor is mounted on a support connected with one end of the fan blade, therefore, the motor does not block the wind direction, and the air enters into the casing directly along the air duct. The invention provides a method for changing the flow path of wind by changing the position of the air inlet of the hair drier, thereby reducing the power consumption of the hair drier. However, the hair dryer also has a problem of loud noise during use and has a low energy utilization rate. US5875562A discloses another widely used side entry blower which mounts a motor within a handle portion and is connected in driving relationship to an impeller by a long vertical shaft to minimize sound and vibration in the handle portion. The large impeller of the present invention blows air downward from the large top air inlet and then passes it outward through the side air outlet to dry the hair. However, the invention is only suitable for low-speed fans (speed of 20000 rpm or less).

Example 1

First, a side-intake hand-held hair dryer according to embodiment 1 of the present invention will be described with reference to fig. 1 to 4. One solution adopted by the present embodiment is to provide a side-inlet hand-held hair dryer, which comprises a main body 10 and a handle 11, wherein the main body 10 comprises a main fluid inlet 101, a fan unit 102, a heating element 103, a fluid flow path 104 and a main fluid outlet 105. As shown in fig. 2 (the direction of the dotted arrow indicates the fluid flow direction), the fluid flow path 104 includes a main fluid path 1041, a side path 1042, and a wall defining path 1043. The fan unit 102 is disposed in the main fluid path 1041, and the fan unit 102 draws fluid into the main fluid path 1041 and transports the fluid through the heating element 103 such that the fluid in the main fluid path 1041 is heated and exits from the main fluid outlet 105. The axial direction of the fan unit 102 is parallel to the main fluid path 1041. The main fluid path 1041 and the side path 1042 meet before the air intake end of the fan unit 102. The fluid drawn by the side path 1042 enters the fan unit 102 through the main fluid path 1041. The port of the side path 1042 includes a first aperture 1061, the first aperture 1061 including a plurality of apertures extending at least partially around an outer wall of the body.

Generally, a fan unit driven by a digital high-speed motor sucks air fluid to provide high-pressure jet air flow, negative pressure is formed if the air fluid at the front end of the fan unit is not sufficiently supplemented, disturbance is caused to the air flow discharged from the rear end of the fan unit, on one hand, the air outlet speed per unit area is reduced, and on the other hand, large air noise is generated due to air flow disturbance and transverse friction. The side path 1042 of the side entry hand held hair dryer of the present invention merges with the main fluid path 1041 at a point where the fluid enters the front end of the fan unit 102. The side path 1042 increases the path of supplementing air fluid, on one hand, increases the wind supplementing speed to reduce the negative pressure to realize the air flow balance, and on the other hand, eliminates the air flow disturbance on the main flow outlet so as to reduce the air noise.

The side path 1042 is perpendicular to the main flow path 1041 and includes two corners 10421. The two corners 10421 are approximately right angles. The two corners 10421 are symmetrically disposed on the side path 1042. The first holes 1061 are symmetrically disposed at both sides of the body 10 and respectively connected to the side paths 1042.

The outer wall of the body 10 adjacent the primary fluid outlet 105 comprises a second aperture 1051, and the second aperture 1051 comprises a plurality of apertures extending at least partially around the body 10. The second aperture 1051 connects the walls to define a path.

The handle 11 is connected to the main body 10 at a position where the fan unit 102 is located. A power cable for supplying power to the fan unit 102 extends through the end of the handle 11. The heating element 103 extends along the body 10 to the primary fluid outlet 105.

The body 10 further comprises a duct extending within the outer wall and an outer wall, the space extending between the duct and the outer wall providing the wall defining the path. The wall defines a path that is annular. The primary fluid inlet 101 includes a third aperture 1011, and the third aperture 1011 includes a plurality of apertures.
