Description
Technical field
The utility model relates to a kind of knob assembly, is related specifically to the knob assembly on a kind of household appliances.
Background technology
Household appliances are of a great variety in the market, and make rapid progress, the requirement of user to product appearance and ease for use is also more and more higher.On existing market, the knob of household appliances setting product work parameter or function generally has two kinds: one is mechanical type, at periphery silk-screen digital calibration or the symbol of knob, correlation parameter or functional mode is set by rotating align certain scale or symbol of knob, another kind is electronic type, its panel is provided with a display device (as LCDs or charactron), electric signal is produced by rotating knob scrambler, electric signal passes to display screen after control module conversion, display screen and servo-actuated show corresponding parameter or function, user sets correlation parameter or functional mode by the information on display screen.
Above-mentioned two kinds of knobs are not enough all to some extent, mechanical knob when setting-up time or temperature equicontinuity parameter, not accurately, because the silk-screen scale of its periphery is limited, when arranging the parameter that scale does not have, user can only rotate to general position, sets a general parameter; And existing electronic type knob, when setup parameter, rotate knob by hand, while stare at the display screen being in its outside with eyes, not very convenient, especially knob and display screen apart from each other when, in addition, display screen also takies the space of product top panel very much.
Utility model content
The purpose of this utility model is exactly the deficiency overcoming existing knob assembly, a kind of display screen is provided to be placed in the knob assembly in knob centre position, make parameter or the functional mode of directly observing display screen display during user's operation knob through the transparent or semitransparent display cover in the middle of knob, thus use more intuitive and convenient, setting accurately, and the space on the panel of product can be saved.
The utility model solves the technical scheme that its technical matters adopts:
The utility model discloses a kind of knob assembly, comprise: be provided with the panel of knob hole, hollow knob, display cover, be provided with display device and the circuit control panel of display screen, knob is placed on panel, coaxial with knob hole, display cover, for transparent or semitransparent, is positioned at the middle part of knob; Also comprise display support and gear train, display support is fixed on panel or on control circuit board, and display device is loaded on display support, and the display location on it is immediately below display cover, and knob is in transmission connection by the scrambler on gear train and panel.When user rotates knob, during by scrambler parameters or function, can observe these parameters or function of showing screen display by transmission display cover, make user's more convenient operation, it is more accurate to set.
Above-mentioned knob assembly, the input end of its gear train is knob, and output terminal is a rotating disk, and the projection on rotating disk and the draw-in groove of scrambler are connected.
Above-mentioned knob assembly, its display screen is electrically connected with control circuit board, such scrambler is converted to electric signal the angular displacement that knob produces, then passes to display screen after the control module conversion of control circuit board, and display screen will show corresponding numerical value or symbol.
In above-mentioned knob assembly, its display cover is an independently part, also can with knob by quadric injection mould, bonding or rivet into and be integrated.
the beneficial effects of the utility model are:
1, knob assembly of the present utility model, can make display screen be placed in the centre position of knob, more directly perceived when making user's operation knob setup parameter or function, sets more accurate.
2, knob assembly of the present utility model, can save the space on the panel of product.
3, knob assembly of the present utility model, can make the outward appearance of product more novel, unusual.

Embodiment
embodiment 1
as shown in Figure 1, Figure 2 and Figure 3, in the present embodiment, the knob 2 of hollow is positioned at the knob hole of panel 1, transparent display cover 3 is arranged in the vacancy of knob 2, display support 5 is fixed on the bottom of panel 1 by screw, knob 2 is limited can not move up and down by the display support 5 of the panel 1 on top and bottom, but can rotate in knob hole.
Display support 5 is provided with two stands stud 15, display device 4 is fixed on this two stud 15 by screw, the display screen 11 of display device 4 is positioned at the below of display cover 3, display screen 11 is by winding displacement 12, plug 13 and be welded in socket on control line plate 8 14 and electrically connect with control circuit board 8, and control circuit board 8 is by the stud of screw lock below panel 1.
Gear train between knob 2 and scrambler 9 is by the external toothing of knob 2 lower end, neutral gear 6, convex tendon 15 on the external toothing of rotating disc 7 and rotating disc 7 forms, (not shown) on the stud that neutral gear 6 is fixed on panel 1, engage with the external toothing of knob 2 and the external toothing of rotating disc 7 simultaneously, when knob 2 rotates, rotated by neutral gear 6 driven rotary dish 7, because the convex tendon 15 on rotating disc 7 snaps in scrambler draw-in groove 10, so the work part of scrambler 9 also rotates and produces electric signal import control module (not shown in FIG.) on control circuit board 8 into thereupon, control module passes to display screen 11 after the conversion of this electric signal again, display screen 11 can demonstrate the parameter or functional mode that are setting servo-actuatedly, thus user can by rotating knob 2 and come setup parameter or functional mode and direct display screen 11 below display cover 3 reading parameter or the functional mode of setting, very intuitive and convenient.
