Abstract
The present invention relates to a blade for a ceiling fan. The present invention comprises plate bodies of the blade for a ceiling fan, which are formed by combining plate single bodies with three angles. The three plate single bodies form different angles so as to form an air cutting plane, an air blocking plane and an air shifting plane.
Description
The present invention relates to a kind of ceiling fan blade, particularly relate to when rotating air-supply can be formed with wind cutting, keep out the wind, effect that wind turning links up, to increase air output and to lower the ceiling fan blade of the blade of windage.
At present along with living standard improves day by day, summer, used ceiling fan was improved towards microcomputerized control, but also have towards direction modelled after an antique, reason is in order to cooperate the style of building, the general domestic ceiling fan of pseudo-classic of being not difficult to find out in the building of elegance is using, not only can set off out the elegant makings of building, main still have blow nice and cool effect summer, ceiling fan blade in the past, invent the patent case No. 4892460 as the U.S., auxiliary blade of lateral margin installing at a supports fan blade, this auxiliary blade forms a curved arc shape, and has thickness, with this supports fan blade assembling place mutually, be formed with the fan blade that a microscler clip slot comes this support of clamping, when wind is made in rotation, wind is by this supports fan blade incision, and the air quantity of being cut is pulled over fully with the curved arc place of this auxiliary blade, to produce big air quantity downward or upward, though can strengthen air output, but this auxiliary blade is suitable consume material and increase cost during fabrication, and this auxiliary blade and mutual clamping place of supports fan blade are also insecure, when rotating speed is fast, because of reaction force, so this auxiliary lobe sector-meeting is loosening,, can rock and have noise if combination is not firm.
The object of the present invention is to provide a kind of wind turning effect that strengthens, and can save the ceiling fan blade of manufacture cost.
Ceiling fan blade of the present invention, the plate body of the ceiling fan blade plate body monomer by three kinds of angles is combined, curved edge on a lateral margin of plate main body forms one, opposite side forms a curved edge down, make this ceiling fan when do rotation air-supply, be different amount mutually because of curved edge, plate main body, following curved edge on being somebody's turn to do, can be formed with wind cutting, keep out the wind, pull out the wind effect, make ceiling fan when wind is made in rotation, strengthen the air quantity of incision because of curved edge on being somebody's turn to do, keep out the wind with this plate main body, pull out wind by the curved edge of this time at last and impel air output to heighten, and can lower windage.
The advantage of ceiling fan blade of the present invention is as follows:
One. because of blade of the present invention itself is one-body molded, firm in structure, make and install very convenient, low cost of manufacture.
Two. when the present invention was installed in the blade mounting use of ceiling fan capstan, no matter motor is a forward or reverse also all the effect of making wind, and just the arrow A direction is to make wind to the floor direction, if oppositely can make wind to ceiling board.
Three. blade of the present invention itself is one-body molded, firm in structure, so when rotating speed was fast, though reaction force strengthens, blade can not rock and not have the noise appearance yet.
The present invention is described in detail below in conjunction with drawings and Examples:
Fig. 1 is the perspective view of ceiling fan blade of the present invention;
Fig. 2 is the plan view of ceiling fan blade of the present invention.
Fig. 3 is the side view of ceiling fan blade of the present invention.
Fig. 4 is the cross-sectional perspective view of the above-mentioned Fig. 1 of the present invention.
Fig. 5 is another embodiment's of a ceiling fan blade of the present invention cut-away perspective view.
Shown in Fig. 1～4, ceiling fan blade of the present invention is the plate body 10 with ceiling fan blade, and at curved edge 101 of lateral margin formation of a plate main body 102, opposite side forms a curved edge 103 down, and the mode of this kind moulding is to be integrally formed as the best.Again as shown in Figure 4, when ceiling fan is installed on the ceiling board when doing the rotation air-supply, just when blade is done as the rotation of arrow A direction do, because should go up curved edge 101, plate main body 102 reaches down, and curved edge 103 is the effects that are three kinds of angles, blade curved edge 101 places and the effect of air B experience formation wind cutting on this earlier, successively along the arrow C direction, when wind is delivered to this plate main body 102 and plate main body 102 form the effects of keeping out the wind, please pay special attention to this is because the distance of blade rotation is by A, last wind drift forms windproof effect to this time curved edge 103 places, and wind is sent along arrow D direction, when making wind, rotation becomes all wind faces so can say the present invention because of curved edge on being formed with, lower windage so strengthen the air quantity of incision, because of keeping out the wind, wind turning effect and cause the increasing air output, this is that fan was beyond one's reach in the past.The present invention is under the big situation of air output, just can reach in the past air output by reducing motor horsepower, if can reach original air output then cost can reduce, and the efficient of ceiling fan is improved, efficient is higher if adopt the motor horsepower of former ceiling fan then definitely can strengthen out wind-force.
As shown in Figure 4, the transverse section of blade be shaped as horn shape, and it is shown in Figure 5, curved edge 103 was formed under the present invention was reached by the upward curved edge 101 of being somebody's turn to do of three kinds of angles, plate main body 102, if three monomers are made continuous curved arc shape, cooperate these three kinds of angles so that to make integral blade form the transverse section be S shape, equally, in last curved edge 101 ' locate to form wind cutting effect, when wind is delivered to 102 ' time of plate main body more in plate main body 102 ' formation effect of keeping out the wind, last wind drift forms the wind turning effect to curved edge 103 down ' locate, and wind is sent, and its effect is the same with horn shape section blade.
Claims (4)
