Description

Multifunctional dining table

One, technical field

The utility model belongs to furniture industry, is used for the exclusive restaurant, hotel and family etc.

Two, background technology

It is fragrant, fresh and tender that chafing dish has a flavor, insulation, and advantage such as stimulate appetite has now swept the country, has begun to development abroad, and annual sales amount reaches 16,000,000,000 yuan, and the problem that its exists is the waste natural gas contaminated environment, does not enter exclusive restaurant as yet.Slaughterhouse, as Beijing instant-boiled mutton, the mutton slaughterhouse in Sichuan etc. have kept now eating now and to have scalded, and taste is fresh and tender, insulation, advantage such as stimulate appetite, but also have the natural gas pollution problem.Cooking is a main food throughout the year, but winter, just can cool off very soon after dish serves.Barbecue is a traditional food among the people, has local flavors such as aquatic foods, perfume (or spice), skin are crisp, be popular, but because the pollution of charcoal fuel also fails to enter exclusive restaurant.Therefore, need overcome the shortcoming of above-mentioned cooking methods, improve its quality, and manage to be incorporated on the dining table, improve China's food and drink level.

The purpose of this utility model provides a kind ofly can finish above-mentioned chafing dish, slaughterhouse, and the general high-frequency induction furnace and the general dining table thereof of temperature pot and roaster are mainly used in grand hotel, and people need blocked shot, and it just provides the function of chafing dinning table; People need eat slaughterhouse, and it just provides the function of slaughterhouse dining table; When people need eat cooking, it just can keep the temperature of cooking; And people need eat when roasting, and it just provides the function of barbecue dining table.

Three, summary of the invention

Technical problem to be solved in the utility model is: a kind of multifunctional dining table, comprise the high-frequency heating system, and rotary desktop, fixedly dining table is characterized by: replace a plurality of electromagnetic oven coils with a public circle ring coil, as the heater coil of different dish classes.

On the circle ring coil, installed a plurality of U-iron magnets with the formation flux loop, and mark has been set, guided waiter to place vegetable dish in heat-stable ceramic desktop relevant position.

Adopt the rolling bearing of being with centering to connect the rotating part of location desktop, the Shang Quan of rolling bearing and following circle connect into integral body by a slidable becket.

The specific embodiment

Below in conjunction with accompanying drawing utility model is described further.

Fig. 1 is the general structure of multifunctional dining table, and it is mainly by fixing dining table, and rotary desktop and electric heater are formed.As Fig. 1, each part of dining table is: 1-heat-stable ceramic plate, 2-plastic stent, 3-rolling bearing, 4-collector ring, 5-attaching nut, the 6-brush, 7-power line, 8-interior loop, 9-central cover, 10-flux loop, the 11-ferromagnet, the 12-exterior loop, 13-is desktop fixedly, 14-supporting seat, 15-electric box.Rolling bearing 3 is used for plastic stent 2 and fixing relatively rotating of desktop 13; Two collector rings 4 are enclosed within respectively on two plastic sheaths, and plastic sheath is connected on the plastic stent by attaching nut 5.

Fig. 2 is the work sheet of high frequency heating coil, also is the A-A sectional view among Fig. 1, and high frequency heating coil is coiling 12 1 circles, and then around inner ring 8 one circles, the loop of high frequency electric also together.Thus, the flux loop of formation is the annular of coiling, in order to reduce the magnetic resistance in loop, in coil bottom several U-iron magnets 11 is arranged.

Fig. 3 is the circuit theory diagrams of high-frequency heating, and entire circuit is made up of phase inverter and the control circuit system that rectification circuit, resonance circuit, SEPP single ended push-pull constitute.Its operation principle is: when the 220V power frequency supply behind collector ring, through after full-wave rectification and choking-winding and the electrochemical capacitor C1 filtering, become direct current.This dc source is to be added on high-power main semiconductor three utmost point VT by heater coil L1.The load of triode VT is the antiresonant circuit that is made of heater coil L1 and capacitor C2.Triode VT plays " current switch " effect according to the pumping signal size, is controlling the current switching among the heater coil L1.Because triode VT break-make speed is quite fast, so pass through the about 20～35kh of power frequency of heater coil L1.Adjust the high frequency power output by control circuit, according to electromagnetic induction principle.Around the heater coil L1 of energising, will produce high-frequency alternating magnetic field.At this moment, metal pan is placed the heater coil top, the magnetic line of force passes ceramic platen and acts on metal pan, has passive eddy current and produce in the pot body, thereby pot is heated.

Fig. 4 is the rolling bearing sectional view, and the circle 3-1 that goes up of rolling bearing is linked to be integral body by screw 3-5 with it by becket 3-4 with following circle 3-2.

Be shown client if when needing blocked shot or slaughterhouse as Fig. 5, remove cover plate 9 by waiter, put chafing dish after, by the situation of centering coil heating.

If be shown client need eat cooking the time as Fig. 6, waiter is put into layout drawing on the dining table with cooking 16, and cooking is except that putting a circle around, and a dish 17 also can be put in the centre.Cooking is by the heater insulation of Internal and external cycle.On the edge of rotary desktop, a broken dash has the decorative pattern 1-1 of band hatching, is used to point out waiter to place cold dish usefulness, these positions on circumference, and induction furnace does not heat.Also can adopt the vinyl disc that does not produce eddy current to contain cold dish.

When putting cooking in the middle of Fig. 7 is shown, after inter panel 9 removed, the heater 1-2 of centre need be raised, the heat-stable ceramic plate of intermediate heater 1-2 has been installed 4 lock handle 1-3 on circumference, with lock handle 1-3 extrapolated after, just be fixed on the seam of heat-stable ceramic 1-4 of outer heater.
