Five, embodiment
, to shown in Figure 4 the first embodiment of the present invention and second embodiment are elaborated below with reference to Fig. 2.
By with reference to the Fig. 2 in the accompanying drawing paper of back so that Fig. 4 when the first embodiment of the present invention and second embodiment are described, for fear of repeat specification, all and the corresponding to part of prior art are directly quoted the drawing symbol of prior art.
Fig. 2 is equipped with the controller assembly structure section schematic diagram of knob for first embodiment of the invention.Fig. 3 is the controller assembly structure section schematic diagram that knob is installed of second embodiment of the invention.Fig. 4 is first embodiment of the invention and second embodiment knob stravismus schematic diagram.
The controller assembly of the first embodiment of the present invention and second embodiment includes following structure substantially: control panel 100, circuit board 20, knob 200 and disengaging prevent structure.
Be formed with knob hole 101 above the control panel 100.Be provided with rotary switch 30 above being arranged on the circuit board 20 of control panel 100 rear sides.Knob 200 is made of handle portion 210 and joint portion 220, and handle portion 210 1 ends are to exposing outside, and the other end is positioned at control panel 100 inside; Joint portion 220 is connected on the rotary switch 30.Just, knob 200 utilizes knob joint portion 220 to be combined in rotary switch 30 upper ends.Break away from and prevent that structure is used to prevent that knob 200 breaks away to the outside of control panel 100.
The knob 40 of prior art and rotary switch 30 just combine by simple insertion, so knob 40 also breaks away from from control panel 10 when breaking away from from rotary switch 30 at an easy rate, cause the danger of losing, and need improve this.Prevent that knob breaks away from structure, is used to prevent that knob 200 breaks away to control panel 100 outsides so be provided with.
As shown in Figure 4, prevent to break away from structure and comprise and stop projection 211, stop that projection 211 is to form in that knob handle portion 210 other end outer periphery are outwards outstanding.In addition, subsidiary ornamental portion 110 on control panel 100, ornamental portion 110 is used to beautify the outward appearance of control panel 100.Ornamental portion 110 1 ends that form around inboard along the knob hole 101 of control panel 100 are to exposing outside, and the other end is positioned at control panel inside.
Moreover, be formed with around in ornamental portion 110 other end inboards and stop holder 111, stop that holder 111 is used to stop to prevent to break away from.
Above-mentionedly stop that projection 211 is formed on control panel 100 the place ahead medial surfaces and keep on the very closely spaced position, perhaps with the stopping on the holder 111 not contacted positions of ornamental portion.When under knob 200 and state that rotary switch 30 combines, operating, along with knob 200 towards the left side or rear side be rotated, the projection 211 that stops that is formed on knob 200 contacts with the place ahead medial surface of control panel 100 or the holder 111 that stops of ornamental portion, and the position that then is touched produces wearing and tearing.In order to prevent that above-mentioned situation from taking place, will stop preferably that projection 211 is formed on the place ahead medial surface of control panel 100 or with ornamental portion and stop that holder 111 keeps on the very closely spaced position.
As shown in Figure 2, by said structure, in the first embodiment of the present invention, be provided with ornamental portion 110 above the control panel 100, knob 200 is provided with to break away from and prevents structure.Just, in the first embodiment of the present invention, the other end of knob handle portion 210 is provided with and stops projection 211.Knob stops that projection 211 and ornamental portion stop that holder 111 keeps very little spacing setting to form.Just, stop that projection 211 is stuck in ornamental portion and stops in the holder 111, prevent to break away to control panel 100 outsides.
Controller assembly of the present invention not necessarily will be arranged on ornamental portion 110 on the control panel 100.
As shown in Figure 3, just, in the second embodiment of the present invention, ornamental portion 110 is not set above the control panel 100, prevents to break away from structure and be arranged on the knob 200.Wherein, identical with first embodiment, stop that projection 211 is arranged on knob handle portion 210 other ends.At this moment, knob stops that projection 211 and the place ahead medial surface of control panel 100 keep very little spacing setting to form.Just, stop that projection 211 is stuck in control panel 100 the place ahead medial surfaces, prevent to break away to control panel 100 outsides.
As mentioned above, prevent to break away from structure and be arranged on the knob 200, can prevent that knob 200 breaks away to the control panel outside.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
