Description
Technical field:
The present invention relates to a kind of new-type apparatus that is used for family kitchen, especially a kind of electric up-down kitchen cabinet of hanging on the family kitchen wall.
Background technology:
Granted publication has been number for the utility model patent of CN2770468Y discloses a kind of electric up-down kitchen cabinet of hanging on the family kitchen wall, it comprise box-shaped no base cabinet body, can be at double-deck storing dish, upper limit position switch, the lower position switch of lifting on the three-section type sliding track on the no base cabinet body madial wall and be used to control decline button and rising button on the control panel that is arranged on the positive lower edge of cabinet of storing dish lifting by motor and elevating mechanism.Elevating mechanism in the above-mentioned utility model has adopted two kinds of similar structures, a kind ofly is: the motor that is arranged on the cabinet top connects a gearbox; The output shaft of gearbox is fixedlyed connected with drive sprocket; Described drive sprocket drives passive sprocket rotation by chain, because certain joint on the described chain is provided with a geometrical clamp, described geometrical clamp is clamped the pin that is located at the inboard mid point of storing dish, therefore when motor moved, chain can drive the storing dish and rise or descend, and the geometrical clamp in this structure is again the contact of upper and lower limit bit switch simultaneously, when geometrical clamp touches the push rod of limit switch, the circuit of elevating mechanism will be cut off, and motor stops operating, and rises or descend promptly to stop.The elevating mechanism of another kind of structure is to adopt the reel and the hoist cable kind of drive: motor is connected a gearbox, the output shaft of gearbox is fixedlyed connected with reel, the hoist cable end is bound in the mid point of storing dish inboard, along with the rotation hoist cable of reel can be rolled-up or transfer, thereby the storing dish is risen or decline, the limit switch of the elevating mechanism of this structure and contact can only be located at the correct position of storing dish and cabinet.
In actual use, though adopt the electric up-down kitchen cabinet of said structure to overcome the defective of accessing article inconvenience in wall-hanging hanging cupboard, but still there is a weak point in it: because described double-deck storing dish is just by wherein being connected rising or the decline of finishing the storing dish on one side with chain or hoist cable, therefore described double-deck storing dish underaction not only in process of rising or falling, and serious jitter phenomenon can take place, especially under the situation of storing dish crank, its jitter phenomenon is even more serious, thereby finally influences the normal use of cabinet.
In addition, though Granted publication number can stop the rotation of motor by limit switch for the utility model patent of CN2770468Y, promptly stop the rising or the decline of storing dish, but because storing dish its speed in the process that rises or descend remains constant, therefore when geometrical clamp or storing dish touch the push rod of limit switch the storing dish can be under very big action of inertia with the strong bump of no base cabinet body generation and produce very big noise, storing dish or do not have the base cabinet body and also can be damaged in the time of seriously because of strong bump.
Summary of the invention:
The technical problem to be solved in the present invention is, provides a kind of lifting flexibly and the electric up-down kitchen cabinet of jitter phenomenon can not take place in the process that rises and descend.
Technical solution of the present invention is that a kind of electric up-down kitchen cabinet with following structure is provided: it comprises no base cabinet body, locker dish and direction switch; Described no base cabinet body top is equipped with motor; Be provided with elevating mechanism between described no base cabinet body and the locker dish; Described no base cabinet body Right Inboard wall is provided with upper limit position switch and lower position switch; Described elevating mechanism comprise the left and right movable pulley that is installed in both sides, locker dish top respectively, respectively be installed in both sides, no base cabinet body top left and right quiet pulley, be installed in no base cabinet body crown center and drive pulley that is connected with motor and left and right belt; Described left and right belt one end is fixed on simultaneously on drive pulley, and its other end is fixed on the left and right fixed bar of being located at left and right quiet pulley next door after being taken up in order of priority and walking around left and right quiet pulley and left and right movable pulley; Described left and right movable pulley and no base cabinet body madial wall are movingly; No base cabinet body madial wall between described upper limit position switch and the lower position switch is provided with speed reducing switch; Described speed reducing switch is connected with the motor controller at no base cabinet body top; Described motor controller is connected with motor.
After adopting above structure, compared with prior art, the present invention has the following advantages: because both sides, locker dish top all flexibly connect by the both sides of belt with no base cabinet body top among the present invention, not only lifting is flexible thereby make the present invention, even and can be in lifting process crank also can remain the movement tendency of steady lifting.After on the no base cabinet body Right Inboard wall between upper limit position switch and the lower position switch speed reducing switch being set, in locker dish process of rising or falling, when left and right movable pulley frame touches speed reducing switch, speed reducing switch can be given the signal of a deceleration of motor controller, thereby the speed of impelling the locker dish to rise or descending slows down, effectively avoid the locker dish to produce very big noise, prevent from the locker dish or do not have the base cabinet body to be damaged because of strong bump because of strong bump takes place for motional inertia rapidly and no base cabinet body.
Above-mentioned left and right movable pulley and no base cabinet body madial wall refer to movingly, and described left and right movable pulley is installed in respectively that the side is provided with chute and can touches in up and down on the left and right movable pulley frame of upper limit position switch and lower position switch; Described two left and right movable pulley frames are separately fixed at both sides, locker dish top; Described no base cabinet body madial wall is provided with the guide rail that matches with chute.
Above-mentioned drive pulley is installed in no base cabinet body crown center and is connected with motor and can adopt following concrete structure: described no base cabinet body crown center is fixed with a drive pulley frame; Be connected with pulley spindle rotationally on the described pulley frame; Described drive pulley is fixed on the pulley spindle; Described pulley spindle one end is fixed with the described worm gear of worm gear and is meshed with worm screw on being located at motor output shaft.
