Abstract

The utility model relates to a human body sensing type rotary disk for an electric dining table, which comprises a rotary table, a rotary disk, a rotary disk support seat and a steel ball. A copper wire inductor is arranged on the bottom edge ring of the rotary table. The copper wire inductor and an electronic control disk are mutually connected. Signals are received and sent by the electronic control disk to make an alternating current motor rotate or stop, so that people can easily touch the copper wire inductor in any directions. Thereby, the rotary table is rotated or stopped according to requirements.

Description

Human body sensing type rotary disc for electric dining table

The utility model is about a kind of human body induction type electric turn table (the application is actually autograph and appends application () for the Taiwan of " Lazy Susan of rotatable tool receptacle ").

Press, the dining table that the dining table of general Chinese restaurant and part family use is to be convenient to taking of dish during the feast, mostly use dining table with round rotating disk, though round rotating disk is really convenient than platform-type dining table in the past, as when running into dish need heat tracing on the dining table, in order to bring into play the spinfunction of round rotating disk, have to be to use the stove and accessory heating of alcohol or charcoal, as when desiring long-time heating food, above-mentioned stove and accessory needs constantly to add fuel, all too inconvenience again; Therefore people have to give up round rotating disk function, so that gas oven that can long-time heating easy to use, electromagnetic oven etc.; In this, the people when during the feast must stand up or bother others to get in generation again when taking not in the presence of dish, have many drawbacks.

The purpose of this utility model provides a kind of human body induction type electric turn table.

The utility model is embodied as a kind of human body induction type electric turn table, comprise turntable, rotating disk, rotating disk bearing and steel ball, wherein this turntable lower edge is installed this rotating disk, and this steel ball of installing between rotating disk and rotating disk bearing, can be plugged in indoor supply socket by the extended plug of rotating disk bearing, so that this this turntable of rotating disk interlock and do relative rotation with this rotating disk bearing; It is characterized in that:

The root edge of this turntable is equipped with the copper cash inductor, this copper cash inductor connects an Electronic Control dish that is positioned at this rotating disk bearing appropriate location, one side of this Electronic Control dish articulates an alternating current motor, make this Electronic Control dish receive the induced signal that produces by staff touches the copper cash inductor, thus control revolution or stop.

For enabling more to understand content of the present utility model in depth, existing with accompanying drawing and cooperate embodiment and be described as follows:

Fig. 1 is an elevational cross-sectional view of the present utility model;

Fig. 2 is an Electronic Control dish schematic diagram of the present utility model;

Fig. 3 is a top view cutaway view of the present utility model;

Fig. 4 is the circuit diagram of Electronic Control dish of the present utility model.

The figure number part:

1 turntable, 11 copper cash inductors

2 rotating disks, 3 rotating disk bearings

31 Electronic Control dishes, 32 alternating current motors

33 plugs, 4 steel balls

A resistance B diode

C capacitor D integrated circuit

E three-dimensional alternating current F bridge rectifier

G resistance H diode

I capacitor J relay

Existing conjunction with figs., figure number are described in detail as follows preferable possible embodiments of the present utility model:

Please consult Fig. 1,2 and cooperate Fig. 3, the utility model comprises: assemblies such as turntable 1, rotating disk 2, rotating disk bearing 3 and steel ball 4; This turntable 1 lower end then is provided with a rotating

disk

2, and 3 of rotating disk 2 and rotating disk bearings are provided with the pivot steel ball 4 of right quantity, so that rotating disk 2 and rotating disk bearing 3 can be pivoted relative to each other, and because of the application is not attaining to the greatest extent to conduct oneself well and improved at mother application, and the most of part of this structure is because of applying for identical with mother, promptly will not go again and give unnecessary details, it is characterized in that:

Turntable 1, be equipped with copper cash inductor 11 in root edge, all can conveniently touch in either direction for people, simultaneously, being positioned at rotating disk bearing 3 and being articulated with its circuit diagram of Electronic Control dish 31(in extended plug 33 appropriate locations then sees also shown in Figure 4), these control panel 31 1 ends are connected with above-mentioned copper cash inductor 11, and end then articulates an alternating current motor 32 in addition, and mat rotating disk bearing 3 extended plugs 33 can be pegged graft indoor socket with power supply;

When touching the set copper cash of this turntable 1 root edge inductor 11, this Electronic Control dish 31 promptly receives induced signal, makes alternating current motor 32 starts that are articulated in Electronic Control dish 31, and driven rotary table 1 rotates; In addition, when people desire to make turntable to stop the rotation, only need touch copper cash inductor 11 once more, even then Electronic Control dish 31 motors 32 stop start, so that this turntable 1 can be stop, a moving turn, and can bring into play very large effect with the improvement of this slight device, and to be solved in female application switch be one fixed, the shortcoming that is difficult to control automatically the turntable turn.

For above-mentioned electronic induction dish 31 can be understood in more detail, special operation principle with the power unit in the electronic induction dish 31, touch-control part and motor control section is described below (referring to Fig. 4 and cooperate Fig. 2), wherein,

Power unit:

1N4004 makes halfwave rectifier by diode, A carries out current limliting via R1 resistance, diode B by 10V/0.5W is stabilized in 10V with voltage again, and the 10V DC voltage of output is carried out filtering by the capacitor C of 100uf/16V, so that export a level and smooth 10V DC voltage, and this 10V DC voltage is received above the circuit of application.

Touch-control part and motor control section:

Constituted by HT-7712 this part integrated circuit D by model, the major function of HT-7712 is the circuit that is used for capacitive sensing, when contact copper cash inductor 11 (for example: people's hand) is sensed a capacitive object, its internal circuit promptly can produce a triggering signal at the 3rd pin (TRIG), use triggering three-dimensional alternating current E and make its conducting, then the alternating voltage of 110V can carry out full-wave rectification via bridge rectifier F, again via the resistance G current limliting of 15K/1W, the filter action of the voltage stabilizing of the diode H of process 5V/1W and the capacitor I of 470uf/16V, and obtain the DC voltage of a level and smooth 5V, this voltage will make the relay J coil be produced magnetic force and alternating current motor 32 will be connected the AC power of 110V, make alternating current motor 32 be rotated; When contact copper cash inductor 11 is sensed capacitive object once again, then the 3rd pin (TRIG) of HT-7712 integrated circuit D just no longer produces the signal that triggers three-dimensional alternating current E, and make three-dimensional alternating current E be in the state of not conducting, lost the supply of DC voltage, then magnetic switch will be in the state of pass, so alternating current motor 32 can not get the 110V ac power supply, also just stop rotation, so go round and begin again, then can reach the purpose of switch electronic device with touching of staff.

From the above, device of the present utility model is different from female application, and has improved effect, should really be the utility model of closing in practicality.
