Abstract
The utility model discloses a low noise large wind quantity super thin type hand drier, comprising an electric machine 5, a blower 8, a ventiduct 7, a heating body 2, a bottom seat 1, a casing 10 and a control circuit. The electric machine 5 is provided with at the central position departure from the bottom seat 10 to make the wind outlet 4 of the hand drier position at the central position of the hand drier. The shaft of the electric machine is provided with a centrifugal blower 8. Two impeller hubs at both sides of the centrifugal blower 8 are respectively provided with a wind inlet 11. Both faces of the impeller can make the wind enter to increase the entering quantity of the wind. The arrangement for the ventiduct 7 is transverse for effectively reducing the thickness of the hand drier. The center of the face of the hand drier is provided with an upward arch arc face; the lowest part of the arc face is provided with a nose-shaped wind outlet 4. The wind outlet 4 is provided with a shutter-shaped wind outlet net cover 3 to reduce the resistance in the process of venting the wind. The inside of the wind outlet 4 is installed the #-shaped heating body 2 knitted by a plurality of heating wires to make the produced heated wind distribute evenly. The electric machine 5 is provided with at the bottom seat 1 by a quakeproof washer 9 for reducing the quake and lowering the noise. The advantages of the utility model is little in occupied space, centered in wind outlet, low in noise, and large in wind venting quantity.
Description
Technical field
The utility model relates to hand dryer, especially a kind of take up room little, two air intakes, air-out placed in the middle, the ultrathin hand dryer of the big air quantity of low noise that air quantity is powerful.
Background technology
At present, hand dryer is organically to be combined by parts such as motor, wind wheel, air channel, calandria, base, shell and control systems.When user's both hands reach the below certain distance of air outlet, machine will be started working automatically, blow out hot blast, dry up hand, and after leaving away, machine quits work automatically.But sell on the market now hand dryer all have such or such drawback, make the consumer not satisfied.Have for air-out placed in the middle, the endways dress in air channel, just can only complete machine thickening, reached 30cm.Give very heavy sensation of people, the position that takes up room is big; Have in order to reduce the thickness of complete machine, the air channel is adorned sidewards, the problem of bringing is that air outlet can not be placed in the middle, can only on the left side or the right air-out, influence attractive in appearance and use; Have in order to improve air output, used high-revolving series excited machine, cause noise big, reached more than 80 decibels; Have in order to reduce noise, use capacitor motor, the thing followed has also reduced air output, can significantly feel hot.
Summary of the invention
The purpose of this utility model is to have the problem that the position is big, air outlet is not placed in the middle, noise is big, air output is little that takes up room at present used hand dryer, provides the big air quantity of a kind of low noise ultrathin hand dryer.
The ultrathin hand dryer of the big air quantity of low noise described in the utility model comprises motor, blower fan, air channel, calandria, base, shell and control circuit.Motor is loaded on and departs from the base center, makes the air outlet of hand dryer be in the center of hand dryer.Centrifugal fan is housed on the motor shaft.Have air inlet on the impeller hub of centrifugal fan both sides, impeller two sides air intake has increased intake.Hand dryer air channel horizontally set has reduced the thickness of hand dryer effectively.The hand dryer front center has an arch cambered surface that makes progress, and cambered surface below has the air outlet of a nose shape.Air outlet is equipped with blinds type air outlet mesh, has reduced wind resistance.Intersecting parallels calandria by the heating wire braiding is housed in the air outlet, makes the hot blast of generation even.Motor is installed on the base by earthquake washer, to reduce vibrations, reduces noise.
Motor adopts capacitor motor.
Control circuit of the present utility model is a routine techniques, can adopt known circuits.
The utility model has the advantages that the position that takes up room is little, air outlet is placed in the middle, noise is little, air output is big.
Description of drawings
Fig. 1 is the structural map of the ultrathin hand dryer of the big air quantity of the utility model low noise;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the left view of Fig. 1.
The specific embodiment
As shown in Figure 1-Figure 3, hand dryer described in the utility model comprises motor 5, blower fan 8, air channel 7, calandria 2, base 1, shell 10 and control circuit.Motor 5 is loaded on and departs from base 10 centers, makes the air outlet 4 of hand dryer be in the center of hand dryer.Centrifugal fan 8 is housed on the motor shaft.Have air inlet 11 on the impeller hub of centrifugal fan 8 both sides, impeller two sides air intake has increased intake.Hand dryer air channel 7 horizontally sets have reduced the thickness of hand dryer effectively.The hand dryer front center has an arch radian, and radian below has the air outlet 4 of a nose shape.Air outlet 4 is equipped with blinds type air outlet mesh 3, has reduced wind resistance.Intersecting parallels calandria 2 by the heating wire braiding is housed in the air outlet 4, makes the hot blast of generation even.Motor 5 is installed on the base 1 by earthquake washer 9, to reduce vibrations, reduces noise.
Centrifugal fan aerodynamic principle, dimensionless parameter are adopted in the utility model hand dryer air channel.Discharge coefficient has reached 0.26, coefficient of total pressure 0.86, specific speed 78.8, power coefficient 0.254, the highest total head internal efficiency 88.Secondly the air channel adopts single-stage double-suction to go into the formula air intake, and do not reducing fan blade intensity, do not influencing under the situation of the degree of balance, perforate in the middle of the impeller hub of fan blade, the effective area that increases intake reaches 40%.Arch radian in conjunction with shell makes air intake smooth more, reaches the effect that intake increases, and has increased air output and has reached 36%.
Had powerful air output to be the basis, the horizontal dress in air channel makes the thickness of complete machine compress half, and the suitable displacement of air channel central point makes air outlet move to the middle position.
The utility model has brought the most direct effect to be energy savings, to save time to the user.Under the situation, owing to used the utility model hand dryer, air output has increased by 36%, thereby makes the dried hand time also shorten 36%, saves energy 36% on year-on-year basis.Indirect effect is a low noise, and is ultra-thin, and air-out placed in the middle is attractive in appearance.
Not changing under the structure situation of former hand dryer, only improved air channel and fan blade, given full play to the efficient of the utility model hand dryer, method is simple and effective.
