Abstract
The utility model relates to a warm air machine. The utility model is composed of a shell body, a cross flow fan, a PTC electric heating element, an electric motor, an air channel, a temperature control element, etc. The utility model is characterized in that the cross flow fan is clamped between in the air channel; an air inlet of the air channel is positioned on the lower part of the cross flow fan; the PTC electric heating element is positioned on upper part of the cross flow fan and an air outlet of the air channel. As the PTC electric heating element is positioned on upper part of the air outlet of the air channel, the air enters from the air inlet of the air channel, the cross flow fan is driven by the electric motor to rotate, the air direction is changed and the air speed is accelerated after entering the air channel, and the air flow uniformly passes through the PTC electric heating element at higher speed. The heat efficiency is improved. As the air channel with special structure is adopted, the air volume is increased, and the noise is reduced.
Description
The utility model belongs to the heating equipment class, relates in particular to a kind of warm-air drier.
Warm-air drier in the market mainly is made up of housing, blower fan, heating and temp-controlling element etc., and the warm-air drier heating that has adopts heating wire, quartz ampoule, halide torch etc., but the easy oxidation of heating wire, service life are short, poor seismic behavior; Quartz ampoule, halide torch heating have heat transfer distances near, and temperature rise is slow, no temperature is from shortcomings such as limit abilities.The warm-air drier that also has adopts PTC ceramic electric heating element, but is made generally in squarely, and electrothermal efficiency fails to give full play to.Warm-air drier on the market often adopts tube-axial fan or centrifugal fan, but the fan delivery of these kinds is little, noise is big.
The purpose of this utility model is exactly that a kind of electrothermal efficiency height, air quantity is big, noise is low warm-air drier will be provided.
A kind of warm-air drier, form by housing, axial-flow fan, PTC heating, motor, air channel and temp-controlling element etc., it is characterized in that axial-flow fan is clipped in the middle of the air channel, the air channel air inlet is positioned at the below of axial-flow fan, and the PTC heating is positioned at the top of axial-flow fan and air channel air outlet.
Because the PTC heating is above the air outlet of air channel, air enters from the air channel air inlet, after the rotation of driven by motor axial-flow fan, air enters the air channel break-in and quickens, make air-flow pass through the PTC heating equably, thereby improved the thermal efficiency, also owing to adopted special air channel structure with higher speed, increase air quantity, reduced noise.
Fig. 1 is the utility model representative side section view;
Fig. 2 is the utility model normal section schematic diagram.
As shown in Figure 1 and Figure 2, the 1st, air channel air inlet, the 2nd, axial-flow fan, the 3rd, primary air separating duct plate, the 4th, air channel air outlet, the 5th, PTC heating, the 6th, air outlet, the 7th, PTC support, the 8th, after wind guidance tape, the 9th, air channel support, the 10th, motor with cup rotor.
As shown in Figure 1, blower fan adopts the mature axial-flow fan 2 of technology on the air-conditioner, and the air channel is made up of primary air separating duct plate 3 and after wind guidance tape 8, and primary air separating duct plate 3 and after wind guidance tape 8 are installed on the air channel support 9.Wherein, the hypomere of primary air separating duct plate has an outside knuckle, and there is one section circular arc that has about quarter turn of certain interval to grow apart from axial-flow fan the centre, and the epimere of primary air separating duct plate constitutes vertical passage with the epimere of after wind guidance tape; The hypomere of after wind guidance tape has and a bit ofly apart from axial-flow fan the circular arc of certain interval is arranged, and an outside knuckle, and bent angles all on the plate of forward and backward air channel are all used smooth arc transition.Large diameter axial-flow fan is included in the air channel, and its below is the air channel air inlet 1 of a flare, can reduce the air intake resistance, increases intake; The circular arc at primary air separating duct plate middle part is the streamlined passage, plays the break-in acceleration; The smooth arc transition of each bent angle mainly is the resistance that reduces wind, makes air not form eddy current in the air channel, and the circular arc of after wind guidance tape hypomere plays and reduces to leak, and increases the effect of blast; The epimere Vertical Channel of forward and backward air channel plate mainly play the guiding role; This special structure, the wind speed that has guaranteed blower fan is higher and noise is less.
As shown in Figure 2, PTC support 7 is contained on the support of air channel, and PTC heating 5 is supported, and guarantees the insulation between PTC heating and the forward and backward air channel plate and apart from air channel air outlet 4 certain distance is arranged.It is flat cellular that the PTC heating is, guarantee that air can contact with the PTC heating to greatest extent, the length of axial-flow fan, air channel and PTC heating is suitable with the outer cover length size in addition, has increased air quantity, has brought into play the thermal efficiency of PTC heating fully.
During use, motor with cup rotor 10 energising backs drive the major diameter axial-flow fan, air is come in from air channel, warm-air drier bottom air inlet, quicken by the air channel break-in, make air-flow pass through cellular PTC heating equably with higher speed, gas flow temperature becomes warm braw after raising, in air outlet 6 inlet chambers.
Warm-air drier air quantity of the present utility model is big, noise is little, the thermal efficiency is high, has higher use value.
