Specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

As shown in Figure 1, a meal desktop one is divided into two parts, between certain air gap is arranged, make it relative motion.Interior round table plate plate 1 edge a plurality of permanent magnets 3 that are equally spaced are set up magnetic field and are constituted mover, and the inward flange of round table plate 2 is equipped with one section winding iron core 4 outside, constitutes stator, and whole dining table becomes a linear stepping motor, by electronic driver control rotation.

As shown in Figure 2, L on the stator core ₀-L ₉It is independent separately to drive winding, is docile and obedient preface wheel flow-thru electrode, produces straight line circulation shifting magnetic field, and polarity is identical with the rotor permanent magnet of closing on, and both produce repulsive force and make the mover rotation.When static, because the proportionate relationship of distance between stator core length and the mover magnet, and make the magnet of mover always have certain that is parked in the stator core scope, when producing the shifting magnetic field, this magnet just moves thereupon.When permanent magnet 3 _BBy L ₀After winding magnetic field is released, permanent magnet 3 _AJust enter in the shifting magnetic field and to move, the rest may be inferred by analogy for it, changes the winding power-up sequence, i.e. shifting magnetic field direction, and mover changes direction of rotation immediately.

As shown in Figure 3,556 ICs ₁Two rate T ₁, T ₂Connect 4017 ICs ₂Input, T ₁Connect 4017 ICs ₂CP end, T ₂Connect 4017 ICs ₂EN end, IC ₂Output Q ₀-Q ₉Corresponding electronic switch VT ₀-VT ₉, electronic switch VT ₀-VT ₉Control L ₀-L ₉Stator drives winding.T ₂＞T ₁, Q ₀-Q ₉Output becomes high level one by one, control VT ₀-VT ₉Be docile and obedient preface and take turns switch current, change frequency and can change motor speed and time intermittently respectively.

Above-mentioned straight line stepping engine and electronic driver are an integral body that interknits interdependence, and its runnability is both resultant effects, and the structure of this electromechanical integration is indivisible.

As shown in Figure 4, on the interior round table plate 1 electric heating plate 5 is arranged, the encapsulation electric heating element is fluted in the middle of the disk body in the disk body, built-in spring and T shape depression bar, and interlock links to each other with metal bar for they, and the metal bar interlock links with electronic switch 6; For electronic switch 6 power supplies also are provided with a dynamic power device, in this device, adorn one section insulation tube 9 in the air-cored axis 8 of table body support frame 7, two collector rings 10 are fixed on pipe 9 outer walls, lead-out wire is connected with electrical equipment on the interior table 1 on the ring 10, be contained in the carbon brush 13 of brush holder 12 the insides on the fixed support 11, contact with 10 of collector rings by spring 14 elastic force, the lead-in wire of carbon brush 13 and power switch are connected.

As shown in Figure 5, the break-make of VS control electric heating element RL power supply, RY926 special IC IC had both triggered VS, showed the triggering state again; TDAO161 and L form the electronic induction switch.

Initially, when not setting fire on the dish pot, spring is upspring T shape depression bar, metal bar is positioned at outside the electronic switch hole, electronic switch Triggerless and ending, heating plate is not worked, when putting chafing dish, the pot body weight is made every effort to overcome the clothes spring force, T shape depression bar is depressed, and the metal bar interlock enters in the electronic switch hole, just produces a triggering signal, change RY926 special IC IC internal trigger state, thereby regulate the heating plate temperature, and do corresponding demonstration by VD1-VD3, on move down a pot body, every action once, that electronic switch will be made successively will be weak, in, strong firepower regulates.

On the dining table panel several hot plates can also be set, the structure working principle of hot plate is the same substantially with heating plate, but does not have temperature adjustment function, and auto switching power supply function is only arranged.Electric heating element adopts the PTC element, utilizes its distinctive self-constant temperature selectivity, has both simplified Electronic Control, and is safe and reliable again.
