Description
Technical field
The present invention relates to a kind of ventilation fan.
Background technique
Ventilation fan is in order to be discharged to indoor contaminated air outside the room, and by the electrical equipment of popularizing.Above-mentioned pollution is meant, the CO2 that is for example produced by people's breathing, or the dust that produces within doors.Have again; Putting down in writing the content of " indoor air should nontoxicly, harmless, no abnormal be smelt flavor " in country's indoor air standard (GB/T 18883-2002); For example: per hour the mean value of NO2 requires in the 0.24mg/m3, and it is in 0.10% that the daily mean of CO2 requires.So, indoorly must be provided with suitable air regenerating device.
In order to efflux out air to the room, though on ventilation fan, be provided with ventilation duct, because the characteristic of machine, the difference of ventilation duct length, and air output is also different.Therefore, on the basis irrelevant,, the output of motor is adjusted through DC (brush DC) motor controller in order to ensure the ventilation volume of necessity with form is set.
As shown in Figure 1, wherein A portion is a partial enlarged drawing.Ventilation fan 1; Be provided with the framework face shield 11 and second face shield 12; And on the space between second face shield 12 and the motor hodmadod 13, be provided with the controller 14 of motor, on controller, be provided with and correspondingly on ventricumbent regulator 15, the second face shields 12 that are used for governor motor output open a control hole 16 in regulator 15 positions; In order to regulation and control regulator 15 under the situation of not opening second face shield 12, parameters such as the air quantity size of setting ventilation fan and late release time.Owing to be often the machine of running, the noise when lowering its running reaches through dual face shield is installed that to reduce its running noise be necessary on hodmadod, and therefore second face shield requires sealing as far as possible to install usually.In addition, influence regulator 15 work in order to prevent steam from getting into control hole 16, it is very little that control hole 16 all designs usually.But nonetheless, under action of negative pressure, still there is steam to get into regulator 15 is made moist.Also because control hole 16 is very little, brought puzzlement for the prefabricated parameter of regulation and control regulator 15 simultaneously.
Summary of the invention
Main purpose of the present invention is to overcome the problems referred to above, and a kind of ventilation fan is provided, and can prevent effectively that regulator from making moist;
Secondary objective of the present invention is, a kind of ventilation fan is provided, and can regulate and control regulator easily.
For realizing above-mentioned purpose; A kind of ventilation fan provided by the invention is provided with framework face shield, second face shield, the controller of motor, regulator, and correspondence is opened a control hole etc. in the regulator position on second face shield; It is characterized in that, on described control hole, establish a waterproof lid.Through water cover of on control hole, setting up defences, protect regulator, carry out effective waterproof.
Described ventilation fan, wherein the two ends of waterproof lid are provided with screens, on second face shield, also are provided with corresponding screens, and the screens at above-mentioned lid two ends is stuck in the screens of second face shield.Fix the waterproof lid through the screens that cooperatively interacts.
Described ventilation fan, wherein the waterproof lid on the regulator is transparent.Because the waterproof lid on the regulator is transparent, so can see demonstration air quantity and the setting situation of time in the waterproof lid.
Described ventilation fan, wherein waterproof lid bottom is provided with packing ring.Protect regulator through lid is set on regulator, in the bottom of waterproof lid packing ring is set again, just can make the waterproof lid directly not contact body and reach directly not contacting body and protecting regulator through packing ring.Can either waterproof, can also prevent because the waterproof lid is taken apart over and over again and directly contacted body the situation that makes the color of body take off.
Described ventilation fan wherein also comprises a knob on the waterproof lid, and this knob stretches out from the control hole on described second face shield.Because waterproof lid and knob are one, and knob stretches out from second face shield, thus do not pull down second face shield situation under also can set machine, and, do not influence water-proof performance yet.
Described ventilation fan, knob wherein with cover is provided with arrow, around above-mentioned regulator, is provided with the sign of expression working state.Through around regulator, identifying numerals such as ventilation fan air quantity and time-delay closing time, just can regulate and control parameters such as air quantity and time, and can know the setting situation of air quantity and time easily.
Described ventilation fan, wherein the arrow on the knob is colored.Through colored arrow, just can conveniently confirm air quantity and time, improve air quantity and the identification of time.
Described ventilation fan, wherein the ventilated port of face shield forms palisade shape, can be as the observation panel of checking the waterproof lid.Need not take face shield apart like this, just can see the position of regulator.Can confirm the setting situation of air quantity and time, have again,, just can see unusual situation if on the regulator of controller, LED is set.
Described ventilation fan is provided with an axle on one side of second face shield, second face shield is opened as door.
Described ventilation fan is provided with electric component at the back side of second face shield, and in this electric component, the DC motor controller is set.
Described ventilation fan, under the state that second face shield is opened, the power line of controller can stretch out from top or side.
In sum, the invention has the advantages that through simple structure to prevent effectively that regulator from making moist, and can the conveniently regulating and controlling regulator.
