Detailed description of the invention
Referring to figs. 1 through Fig. 4, the utility model hand dryer embodiment is described further.
The present embodiment hand dryer, comprise shell 1, control circuit board, inductor, motor, heating wire, the bottom of shell 1 has air outlet 2, sensing hole, air inlet 3, the bottom of described shell 1 is provided with the chimney fan 4 that extends shell 1 downwards, described chimney fan 4 and air outlet 2 UNICOMs, the opening down setting of described chimney fan 4, the opening part of described chimney fan 4 is provided with under duty to be opened by wind drive, and the lid 5 of closing by weight-driven under cut-off state.Chimney fan 4 and air outlet 2 UNICOMs; chimney fan 4 opening be air outlet 2; abandon the mode that ventilation fence is only set at air outlet 2 places in the past; change and the mode of lid 5 is set at air outlet 2; lid 5 can hide air outlet 2 completely; compare and play better protective effect in the past, dustproof, humidity resistance is better.And the lid 5 arranging can not have influence on user's use; it can automatically open lid 5 by wind-force effect in the time that hand dryer is worked; and in the time that stopping, hand dryer closes by lid 5 self gravitation effects; use very convenient; lid 5, for this hand dryer provides effective protection, can, without the members such as ventilation fence are set separately, can not exert an influence to air-out effect; wind-force is powerful, and dry hand efficiency is higher.
Described chimney fan 4 is hollow quadrangular shape, the sidewall of the wherein a pair of symmetry of described chimney fan 4 is all hinged with L-shaped side cover 51, in hinged place, the opening part to chimney fan 4 extends described two side covers 51, described two side covers 51 hide the opening of chimney fan 4 in the direction bending of relative another side cover 51 of opening part of chimney fan 4, described two side covers 51 are equipped with in hinged place to be through to and stir sheet 52 in chimney fan 4, described in stir sheet 52 relative air outlet 2 places the side direction setting that tilts.Chimney fan 4 is hollow quadrangular shape, its opening part is also this shape, by its wherein a pair of symmetry side walls hinged two side covers 51 are set, the opening part that two side covers 51 all extend to chimney fan 4 bends towards another side cover 51, the kink of two side covers 51 forms together lid 5 opening of chimney fan 4 is hidden, and two side covers 51 are provided with and stir sheet 52 in hinged place is all through to chimney fan 4, stirring sheet 52 is inclined upwardly, air-out is played the effect of a resistance, sense after staff at inductor, machine operation, air outlet 2 air-out, wind-force plays a downward thrust in chimney fan 4 places to stirring sheet 52, because side cover 51 is for to be articulated with on the sidewall of chimney fan 4, stir sheet 52 wind-engaging power effects to pressing down, therefore 51 of side covers are to both sides perk, thereby the opening of chimney fan 4 is opened, hand dryer is normally worked, after dry hand finishes, because air outlet 2 is arranged at shell 1 bottom, and the outlet of chimney fan 4 is also downward setting, side cover 51 now can be subject to Action of Gravity Field and turn over downwards, thereby by the vent cover of chimney fan 4, simple in structure, convenient and practical, play the function that automatic control air outlet 2 opens and closes.Certainly the L-shaped setting of side cover 51 herein and chimney fan 4 are hollow quadrangular shape and are preferred embodiment of the present utility model, the easier side cover 51 of chimney fan 4 of quadrangular shape is hinged on its sidewall, if cylindric, the sidewall of its circular arc is unfavorable for the hinged of side cover 51, the hinged structure of side cover 51 is mainly rotated and is realized by being sheathed on the fixed axis 41 that chimney fan 4 sidewalls are fixedly installed, hinged place is provided with the otch connecting in chimney fan 4, stir sheet 52 and be wholely set with side cover 51, stir sheet 52 for penetrating in otch.Side cover 51 and stir sheet 52 and be the lighter material of employing and make, the consideration of mainly more easily digging based on it, what adopt is plastic material herein, because its material adopting is all lighter, under by wind-force effect, to make it dig the wind-force that does not need waste larger, stir sheet 52 and will be far smaller than to the obstruction effect of wind-force the ventilation fence being in the past fixedly installed, therefore the utility model hand dryer has stronger air-out effect, and dry hand efficiency is also higher.The shape of side cover 51 also can adopt the shape of similar ∠ herein, be mainly acute angle based on this shape angle, and between the open end of chimney fan 4 and sidewall, be right angle, its shape can not with its laminating, affect overall aesthetic property, therefore do not adopt this shape, and L shaped its angle is just right angle, therefore using the L shaped preferable shape as side cover 51.
In described chimney fan 4, be fixedly connected with the partition 42 arranging towards chimney fan 4 opening parts, chimney fan 4 is divided into a main wind outlet area 43 and side air-out district 44 by described partition 42, and described two are stirred sheet 52 and are placed in respectively in Liang Ge side air-out district 44.Partition 42 can will be divided into the clear and definite several regions of effect in chimney fan 4, main wind outlet area 43 is mainly used in drying hand, and side air-out district 44 is for providing a part of wind-force to open two side covers 51, and the wind-force effect that both sides side cover 51 is subject to is more balanced, the angle of opening is almost consistent, uses more convenient.
With reference to Fig. 4, described in stir sheet 52 relative air outlets 2 a side be the cambered surface 521 of depression.The cambered surface 521 that is set to depression by stirring a side of sheet 52 relative air outlets 2 can effectively strengthen this side and be subject to wind-force and do the lifting surface area of used time, and side cover 51 is more easily opened by wind-force effect, accelerates the speed that it is opened, more convenient user's use.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, all within design concept of the present utility model, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
