Specific embodiment
In conjunction with referring to FIG. 1 to FIG. 4, Fig. 1 is the cross-sectional configuration schematic diagram of warm-air drier in one embodiment of the invention.Root
According to the embodiment of the present invention, a kind of warm-air drier, including air flow duct 1, air stream drives component are provided, at the air stream drives component
In the air flow duct 1, so that air-flow flows in the air flow duct 1, the air flow duct 1 includes the first air duct board
11, first air duct board 11 has volute tongue portion 12, and the air stream drives component includes impeller 2, and the diameter of the impeller 2 is
φ, the impeller 2 radially, the minimum spacing of the volute tongue portion 12 and the impeller 2 is A, 3 φ/80≤A≤5 φ/
80, in the technical solution, between the volute tongue portion 12 and the impeller 2 to the first air duct board 11 in the air flow duct 1
Away from optimization design, make region of the air-flow in the air flow duct 1 between the impeller 2 and first air duct board 11
Flowing is more smoothly under the premise of guaranteeing wind pressure out and wind speed, to reduce the pneumatic noise of warm-air drier, promotes warm-air drier
Comfort.
Further, the air flow duct 1 further includes the second air duct board 13, second air duct board 13 and first wind
Guidance tape 11 is in the circumferential two sides of the impeller 2, and second air duct board 13 has snail throat 14, in the radial direction of the impeller 2
On, the minimum spacing of the snail throat 14 and the impeller 2 is B, 3 φ/80≤B≤4 φ/80.In the technical solution, by right
The optimization design of spacing, makes the gas in the air flow duct 1 between the snail throat 14 and the impeller 2 of second air duct board 13
Flow the flowing in region between the impeller 2 and second air duct board 13 under the premise of guaranteeing wind pressure out and wind speed more
To be smooth, to further decrease the pneumatic noise of warm-air drier, the comfort of warm-air drier is promoted.
Further, the warm-air drier further includes first shell 3, the impeller 2 radially, the first shell
3 and the minimum spacing of the impeller 2 are L, 25 φ/80 < L, in the technical solution to the first shell 3 and the impeller 2 it
Between radial spacing limited, that is, give the minimum dimension of the L, the purpose of setting of best size at this time, is
The too small gap for causing to be formed between the first shell 3 and the impeller 2 of the L value is excessively narrow in order to prevent, described
Loud, shrill and long sound sound is generated when impeller 2 rotates, of course it is to be appreciated that the maximum distance of L can be closed according to the overall dimensions of warm-air drier
Reason selection.
The air flow duct 1 has wind outlet section, and the PTC for example above-mentioned of heating element 4 is equipped in the wind outlet section, described to add
Thermal part 4 is located in the wind outlet section, and the air-flow after enabling heating is directly flowed out from the warm-air drier, so as to improve
Hot wind enters the initial temperature in heating space, and then guarantees heating efficiency.Since the impeller 2 mostly uses moulding to be made greatly,
Therefore in order to prevent the heating element 4 apart from its heat radiation closely is generated to it excessively after cause structural failure, it is preferable that it is described plus

Maximum distance can be reasonably selected according to the overall dimensions of warm-air drier.
In general, when the warm-air drier is wall-hanging-type warm-air machine, at this point, its generally to hang on heating space higher
Position, therefore, the air outlet angle of adjustable warm wind air-flow is to improve the comfort of warm-air drier, it is preferable that the warm-air drier is also
Including air outlet grate 5, the air outlet grate 5 is in the downstream of outlet air air-flow, and in the air outlet grate 5 outlet air air-flow direction
With vertical direction formed angle C, 25 °≤C≤30 °, best C=27 °.Further, the warm-air drier further includes second shell
Body 6, third shell 7, the second shell 6 are oppositely arranged with the first shell 3, and the third shell 7 is connected to described
Between one shell 3 and the second shell 6, it is configured with the first air inlet 61 in the second shell 6, on the third shell 7
It is all configured with the second air inlet 71, in the technical solution, air inlet is set simultaneously in the second shell 6 and third shell 7,
The intake of warm-air drier can greatly be improved, to further ensure the air output and heating efficiency of warm-air drier.It can be with
Understand, when the warm-air drier is wall-hanging-type warm-air machine, the first shell 3 is procapsid, and the second shell 6 is
For back casing, the third shell 7 is top shell body, and the first air inlet 61, the second air inlet 71 at this time is then provided with rear shell
It on body and top shell body, rather than is located on procapsid, it ensure that the aesthetic appearance of warm-air drier.Further, described second
There is the sunk area being recessed toward 3 side of first shell, first air inlet 61 is set to described recessed on shell 6
It falls on region, and when the warm-air drier and wall or other external bearer parts are installed, the sunk area and cooperation metope
Between form air intake passage, to further ensure the intake of wall-hanging-type warm-air machine.
Fig. 2 gives warm-air drier in the prior art into Fig. 4 and exists with the warm-air drier for using technical solution of the present invention
Heating is carried out over time in same heating space, and the distribution situation of temperature layer in the heating space can be obvious
It learns, using the warm-air drier of technical solution of the present invention at 30 minutes and 60 minutes, the accounting of the temperature higher level in heating space
Broader namely hot wind is closer to ground, therefore the comfort of warm-air drier of the invention is stronger.
Due to use wall-hanging-type warm-air machine of the invention experiment proves that, noise can be reduced to 40dB hereinafter, outlet air
