The specific embodiment
Describe the present invention below with reference to each embodiment shown in the drawings.But these embodiment do not limit the present invention, and the conversion on the structure that those of ordinary skill in the art makes according to these embodiment, method or the function all is included in protection scope of the present invention.
See also illustrated in figures 1 and 2ly, an embodiment of the present invention refrigerator comprises casing 1, drawer and driving mechanism 2.Have in the casing 1 hold drawer between chamber 11, be respectively arranged with guide member 111 on the left and right sides sidewall of a chamber 11, drawer can by with guide member 111 cooperate the turnover between chamber 11, in addition, guide member 111 is also played a supporting role to drawer.Drawer among the present invention is the drawer with door body structure, and namely the front end of drawer is provided with drawer door body 3, and the drawer door body can be closed casing 1.
Drawer door body 3 is provided with signal input apparatus and elastic device 32, in the present embodiment, signal input apparatus is touch key-press 31, when the user wants to open drawer, can realize the signal input by touching touch key-press 31, certainly, in other embodiments, signal input apparatus also can be touch-screen, button etc.Elastic device 32 comprises the connecting plate 321 that is fixed on the drawer door body 3 and the spring 322 that is connected and stretches out drawer door body rear surface with connecting plate 321, realizes electrically connecting by first lead 4 between touch key-press 31 and the connecting plate 321.Described casing 1 corresponding spring 322 is provided with contact chip 5, and this contact chip 5 can be metal material, also can be conductive plastic, as long as can conduct electricity.In addition, also be provided with control device on the casing 1, in the present embodiment, control device is control panel 6, realizes electrically connecting by second lead 7 between described contact chip 5 and the control panel 6.When the drawer door body was closed, spring 322 contacted with contact chip 5, thereby made the touch key-press 31 on the drawer door body 3 realize electrically conducting with the control panel 6 on the casing 1.Why being set to elastic device 32 contacts with contact chip 5, be in order to guarantee contact stabilization, even cooperate between drawer door body 3 and the casing 1 and deviation occurs, elastic device 32 also can compensate by the flexible of spring 322, guarantees that touch key-press 31 and control panel 6 keep conductings.
When the people touches touch key-press 31, touch signal will be passed to control panel 6 by first lead 4, elastic device 32, contact chip 5, second lead 7 successively.After control panel 6 detected input signal, drawer was pushed in 2 operations of control driving mechanism open.
Certainly, in other embodiments, also elastic device 32 can be arranged on the casing 1, and contact chip 5 is arranged on the drawer door body 3, can realize goal of the invention of the present invention equally.
See also shown in Figure 3ly, the below that driving mechanism 2 is located at drawer be used for to drive drawer and shifts out a chamber 11, and particularly, driving mechanism 2 drives drawers can move forward predetermined length, and namely drawer stroke forward is a predefined fixed value.
In the present invention, driving mechanism 2 comprises worm screw 21, worm gear 22, gear 23, tooth bar 24 and driver 25.Tooth bar 24 is located at the bottom of drawer and extends along fore-and-aft direction, and tooth bar 24 is preferred and drawer is integrally formed, makes things convenient for production and processing thus, has simplified production technology, has improved the intensity of tooth bar 24 simultaneously.Alternatively, tooth bar 24 removably is located at the bottom of drawer, for example snaps into drawer bottom by buckle structure or is fastened on the bottom of drawer by screw.Gear 23 cooperates with tooth bar 24, rotatablely moving of gear 23 can be converted to the rectilinear motion of tooth bar 24, and then drives drawer shifts out a chamber 11.Gear 23 simultaneously and worm gear 22 engagements, and worm gear 22 and worm screw 21 engagements, 21 of worm screws link to each other with driver 25, alternatively, driver 25 is motor.That is, 21 rotations of motor-driven worm screw, worm screw 21 drives worm gear 22 rotations, 23 rotations of worm gear 22 driven gears, gear 23 drives tooth bar 24 and does rectilinear motion, thereby power is passed to tooth bar by motor.Preferably, gear 23 comprises external gear 231 and the internal gear 232 of synchronous rotation, external gear 231 and worm gear 22 engagements, and internal gear 232 cooperates with tooth bar 24.Not only transmission efficiency height of rack-and-pinion, worm and gear transmission is set, and reliable transmission, accurate, gear and tooth bar are arranged on the bottom of drawer simultaneously, can also carry out effective support to drawer, share the weight of drawer, make drawer more steady in moving process.
Further, tooth bar 24 is respectively equipped with first cam 241 and second cam 242 at fore-and-aft direction, when a chamber 11 sidewalls are provided with awareness tool 8, the first cams 241 and contact with awareness tool 8, show that tooth bar 24 is in initial position, this moment, drawer was in closed condition; When second cam 242 contacts with awareness tool 8, show that tooth bar 24 is in maximum position, this moment, driver 25 stopped to drive, and corresponding drawer draws back maximum position.
The present invention can guarantee when the door body is closed that by on casing, drawer door body elastic device and contact chip being set respectively signal input apparatus and control device electrically conduct, and when drawer was opened, elastic device and contact chip disconnected, and simple in structure, cost is low.
Be to be understood that, though this specification is described according to embodiment, but be not that each embodiment only comprises an independently technical scheme, this narrating mode of specification only is for clarity sake, those skilled in the art should make specification as a whole, technical scheme in each embodiment also can form other embodiments that it will be appreciated by those skilled in the art that through appropriate combination.
Above listed a series of detailed description only is specifying at feasibility embodiment of the present invention; they are not in order to limiting protection scope of the present invention, allly do not break away from equivalent embodiment or the change that skill spirit of the present invention does and all should be included within protection scope of the present invention.
