Abstract

The utility model relates to a hidden type ceiling fan which comprises an electric motor, a hanging rod of an electric motor positioning component and fan blades connected with the rotating shaft of the electric motor. The hidden type ceiling fan is characterized in that a supporter is fixed on the rotating shaft of the electric motor, and the fan blades are distributed on the identical circumference of the supporter and movably hinged with the supporter. In addition, a lamp bracket is fixed at the lower part of the electric motor positioning component or the stator casing, and an illuminator is installed in the lamp bracket so that the hidden type ceiling fan is also provided with the illuminating function. The hidden type ceiling fan has the advantages that the design is rational, the structure is simple, when the hidden type ceiling fan is not used, the fan blades are naturally sagged, the volume of the hidden type ceiling fan after being folded is small, the appearance is variable, simultaneously, not only the illuminator arranged at the lower part of the ceiling fan has the decorative function and the illuminating function, but also the operation of the illuminating part can not be effected by the ceiling fan whether to work or not, the hidden type ceiling fan achieves the confluent and mutual separate effect, and can meet the requirements of lighting and fanning in the public places such as in families and offices.

Description

Concealed ceiling fan

Technical field:

The utility model relates to a kind of ceiling fan, the concealed ceiling fan that especially a kind of fan blade can be collected automatically.

Background technique:

Be accustomed to the people that lived in the metro because can be for the manor of their domination also that space with regard to indicating on the title, so the rational and efficient use of floor space and fully the family of decoration oneself also just become a kind of common recognition of current people.And from selling fiery omnifarious various Soft wind electric fans, little desk fan, stand fan, air conditioning fan on the market, just people still have the stronger market demand to this more traditional mode of enjoying the cool of fan as can be known.And no matter the style of current these fans of being sold on the market and effect how, all have a relatively significant disadvantage, that is exactly relatively to take the space that we lived, and making original is not very big family just, more seems crowded in disorder.And with regard to the present institute in market product sold in price, more common price is low spot slightly, and those wear the product that magnificent coat is being flaunted banners such as air purification, oxygen bar, room, natural wind, intelligent digital remote control, their price is being lacked big hundreds of, thousands of at most, more having very and then quoting 2 to 3,000 yuan price.

The tradition ceiling fan is specifically energy-conservation, cheap, use is controlled conveniently, have the effect of air ventilation again concurrently, all the time go back the one seat of occuping market, but its structure and outward appearance and modern house decorate sound of laughing not it, also limited to its using scope, how to improve the construction profile of ceiling fan, make its richer ornamental research object that promptly becomes the manufacturer.

Summary of the invention:

The purpose of this utility model is the concealed ceiling fan that a kind of fan blade of design can automatic sagging folding after quitting work rises.

Technical solutions of the utility model are achieved in that a kind of concealed ceiling fan, include motor, be hung with the suspension rod and the fan blade that is connected with machine shaft of motor bonding part, it is characterized in that being fixed with on the machine shaft support, fan blade is distributed on the same circumference of support, and becomes to be movably hinged with support.Be movably hinged owing to adopt, when the driven by motor fan blade was rotated, the lift that windage produces was extremely horizontal with the fan blade elevate a turnable ladder, and the fan blade of rotation promptly produces the pectinid effect downwards.

Fan blade is to be positioned on the support axle bed to form by a horizontal bearing pin to be movably hinged, and can reduce fan blade elevate a turnable ladder and the resistance when sagging like this.

Machine shaft is a hollow shaft, and support is positioned at the motor top, and suspension rod passes hollow rotating shaft, and bottom and motor bonding part fix.Sagging fan blade can wrap in motor wherein, and the richer variation of outward appearance.

In addition, stretch out outside the motor lower end of suspension rod, is fixed with lamp bracket in the suspension rod underpart, in this lamp bracket luminous body is installed.Make ceiling fan also have illumination function.

The utlity model has characteristics reasonable in design, simple in structure, fan blade is sagging naturally when not working, and volume is little after the folding, and outward appearance is rich to be changed, simultaneously, also can install luminous body additional in the ceiling fan bottom, utilize lamp bracket to intersperse and decorate the fan of having collected, formation had both had decorating action, illumination function is arranged again, and no matter whether ceiling fan work does not all influence the work of illumination section, reaches not only to merge but also effect independently mutually, satisfies the need of public place daylighting such as house, office and pectinid.
