CN2461109Y - Device for displaying adjusting signs of electric fan - Google Patents

Abstract

The utility model relates to a device for displaying adjusting signs of an electric fan. A group of rear projection type indicating light sign word film display device and a group of window type condensation irradiation sign word film display device with an illuminating light are combined to form the utility model. The illuminating light is arranged between the lower part of a masking frame at the edge of a transparent face mask and a sign word film. The light of the illuminating light is blocked and reflected in a directional mode by the masking frame. The sign word film is uniformly illuminated. The utility model can not lead eyes of a user to be directly projected. When the user is in a room and in a place with insufficient light at night, the user can clearly see various function sign words, can accurately carry out the speed control, the timing, the head shaking, the angle changing and the wind types of an electric fan, and can accurately select and adjust the time and the program.

Description

A kind of electric fan regulating mark display

The utility model relates to a kind of adjusting identifier display of electric fan, especially is the multi-functional adjusting sign of a kind of electric fan high definition display device.

In the prior art, the wind speed of electric fan, shake the head, regularly, angle, the selection of wind type is put the feast-brand mark of setting the tone and is known display mode, great majority are printing identification characters and presenting on the electric fan panel, limited by positions of panels, these identification characters can not be too big, when indoor light does not reach under the situation at night by force, these tiny functions are regulated identification character and just are difficult to differentiate, during operation, though the user can see that the direct-injection type of each pilot lamp hot spot is beated and flash, extremely difficult see clearly be positioned at the other character and concrete parameter that is backlight state of hot spot, the hot spot irradiation is strong more, dazzle the eyes more, the user can only be memoriter and impression, to each concrete function program do the selection of conjecture property with put fixed, obviously, this backlight type identification character display mode is need be improved.

The purpose of this utility model is to provide a kind of window type electric fan regulating mark display with local focus irradiation light source.

The utility model comprises housing, base plate, sign pilot lamp, identifier word film, transparent face mask, the transparent face mask edge is shaped on the lighttight masking frame of a frame, below the masking frame and between the identifier word film illuminating lamp is housed, below masking frame, have perforation on the housing wall adjacent with identifier word film edge, perforation under the illuminating lamp luminous point covers along masking frame is arranged, and bored a hole and the directional rays of masking frame is blocked reflection, make the illumination of illuminating lamp be orientation and be projeced on transparent light guide piece and the identifier word film.The edge of the transparent light guide piece that mounts on the identifier word film is shaped on incident ray scattering curved surface, when illumination lamp ignition, be subjected to masking frame, the light that orientation is blocked sees through the evenly clear identifier word film that illuminates of transparent light guide piece, but can not cause direct projection, thereby form the focusing form observing effect of a cover high definition to user's ocular vision.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is the structural representation of the utility model.

With reference to Fig. 1, the various sign pilot lamp (3) of the different functions of use states of representative are housed on the base plate on charged road (2), base plate (2) is contained in below the housing (1), housing (1) respectively indicates in correspondence on the position of pilot lamp (3) and has lamp hole (6), and the light direct projection that allows respectively to indicate pilot lamp (3) is passed, identifier word film (8) is printed on functions of use comment and bar number, be mounted on above the housing (1), and corresponding one by one concrete function and the state that respectively indicates pilot lamp (3) rear-projection direct projection hot spot that illustrate, form one group of back projection type cursor character backlight display device; On identifier word film (8), mount transparent light guide piece (9), transparent light guide piece (9) edge is shaped on directional rays incident scattering curved surface (10), transparent face mask (11) edge is printed on the lighttight masking frame of a frame (12), below masking frame (12), between transparent light guide piece (9) and identifier word film (8) edge, illuminating lamp (5) is housed, the perforation (7) that the pin (4) of illuminating lamp (5) passes on adjacent housing (1) wall of identifier word film (8) is connected on the base plate (2) on charged road, illuminating lamp (5) head luminous point can pass perforation (7) and be arranged in below the range of defilade of masking frame (12), when illuminating lamp (5) energising is lighted, its light is subjected to masking frame (11) and perforation (7) orientation to block reflection, uniform irradiation is on transparent light guide piece (9) and identifier word film (8), and don't the meeting direct projection is in user's eyes, so be combined in the complete window type electric fan regulating mark display that carries lighting source of a cover.

The utility model provides a kind of adjusting identifier display of high definition for the multi-functional adjusting operation of electric fan, the user is no matter under night, the not enough situation of any ambient lighting on daytime, can both clearly see the character on the identifier word film (8) in electric fan housing (1) form, implement the every function selecting and the adjusting of electric fan exactly, it is applicable in various electric fans and uses.

Claims (1)

1, a kind of electric fan regulating mark display, it comprises housing base plate, sign pilot lamp, identifier word film, transparent face mask, it is characterized in that: illuminating lamp and transparent light guide piece are housed between transparent face mask and the identifier word film, the transparent face mask edge is shaped on the lighttight masking frame of a frame, have perforation below the masking frame and on the housing wall between the identifier word film edge, the illuminating lamp luminous point is arranged along the perforation under the masking frame, and bored a hole and the directional rays of masking frame is blocked reflection, transparent light guide piece edge is shaped on the light scatter curved surface.
