Detailed description of the invention
Describe the present invention below with reference to each embodiment shown in the drawings.But these embodiments do not limit the present invention, the structure that those of ordinary skill in the art makes according to these embodiments, method or conversion functionally are all included in protection scope of the present invention.
Refer to shown in Fig. 1 and Fig. 2, an embodiment of the present invention refrigerator comprises casing 1, drawer and driving mechanism 2.Have in casing 1 and hold room 11 between drawer, the left and right sidewall of a room 11 is respectively arranged with guide member 111, drawer by with guide member 111 coordinate pass in and out between room 11, in addition, guide member 111 is also played a supporting role to drawer.Drawer in 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 drawer door body can close 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 user wants to open drawer, signal input is realized, certainly, in other embodiments by touching touch key-press 31, signal input apparatus also can be touch-screen, button etc.Elastic device 32 comprises the connecting plate 321 that is fixed in drawer door body 3 and is connected with connecting plate 321 and stretches out the spring 322 of drawer door body rear surface, realizes being electrically connected between touch key-press 31 and connecting plate 321 by the first wire 4.The corresponding spring 322 of described casing 1 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, casing 1 is also provided with control device, in the present embodiment, control device is control panel 6, realizes being electrically connected between described contact chip 5 and control panel 6 by the second wire 7.When drawer door body is closed, spring 322 contacts with contact chip 5, thus makes the touch key-press 31 in drawer door body 3 realize electrically conducting with the control panel 6 on casing 1.Why be set to elastic device 32 contact with contact chip 5, to ensure contact stabilization, even if coordinate between drawer door body 3 with casing 1 and occur deviation, elastic device 32 also compensates by the flexible of spring 322, guarantees that touch key-press 31 and control panel 6 keep conducting.
When there being people to touch touch key-press 31, touch signal will be passed to control panel 6 by the first wire 4, elastic device 32, contact chip 5, second wire 7 successively.After control panel 6 detects input signal, control driving mechanism 2 and run, drawer is pushed open.
Certainly, in other embodiments, also elastic device 32 can be arranged on casing 1, and contact chip 5 is arranged in drawer door body 3, goal of the invention of the present invention can be realized equally.
Refer to shown in Fig. 3, a room 11 is shifted out for driving drawer in the below that driving mechanism 2 is located at drawer, and particularly, driving mechanism 2 drives drawer to move forward predetermined length, and namely drawer stroke is forward a fixed value preset.
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 the longitudinal direction, tooth bar 24 preferably and drawer be integrally formed, facilitate production and processing thus, simplify production technology, improve the intensity of tooth bar 24 simultaneously.Alternatively, tooth bar 24 is removably located at the bottom of drawer, such as, snap into drawer bottom by buckle structure or by the bottom of screw fastening at drawer.Gear 23 coordinates with tooth bar 24, the rotary motion of gear 23 can be converted to the rectilinear motion of tooth bar 24, and then drives drawer shifts out a room 11.Gear 23 engages with worm gear 22 simultaneously, and worm gear 22 engages with worm screw 21, and worm screw 21 is connected with driver 25, and alternatively, driver 25 is motor.That is, motor drives worm screw 21 to rotate, and worm screw 21 drives worm gear 22 to rotate, and worm gear 22 driven gear 23 rotates, and gear 23 is with carry-over bar 24 to do rectilinear motion, thus power is passed to tooth bar by motor.Preferably, gear 23 comprises external gear 231 and the internal gear 232 of synchronous rotary, and external gear 231 engages with worm gear 22, and internal gear 232 coordinates with tooth bar 24.Not only transmission efficiency is high to arrange rack-and-pinion, Worm Wheel System, and reliable transmission, accurately, gear and tooth bar are arranged on the bottom of drawer simultaneously, effectively can also support, share the weight of drawer, make drawer more steady in moving process to drawer.
Further, tooth bar 24 is respectively equipped with the first cam 241 and the second cam 242 in the longitudinal direction, and a room 11 sidewall is provided with awareness tool 8, when the first cam 241 contacts with awareness tool 8, show that tooth bar 24 is in initial position, now drawer is in closed condition; When second cam 242 contacts with awareness tool 8, show that tooth bar 24 is in maximum position, now driver 25 stops driving, and corresponding drawer open is to maximum position.
The present invention, by arranging elastic device and contact chip respectively in casing, drawer door body, can ensure that signal input apparatus and control device electrically conduct, and when drawer is opened, elastic device and contact chip disconnects when door body is closed, and structure is simple, and cost is low.
Be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
A series of detailed description listed is above only illustrating for feasibility embodiment of the present invention; they are also not used to limit the scope of the invention, all do not depart from the skill of the present invention equivalent implementations done of spirit or change all should be included within protection scope of the present invention.
