Abstract
An electromagnetic type heating coffee machine comprises a shell body. A water tank, a water pump, a heating component and a switch power supply are matched with each other and are arranged inside the shell body. The heating component comprises a water-through pipe which is made of magnetism-electricity conducting materials. A coil disc which is matched with the water-through pipe is arranged. The coil disc generates an alternating magnetic field under the control of a coil oscillating drive circuit which is driven by a singlechip computer. The singlechip computer is communicated with the switch power supply. The structure is simple, real-time heating can be guaranteed, and heating efficiency is high.

3) because the accumulation of heat of heat-generating disc is limited, the mug amount of single glass of Hot Coffee is limited, can not realize the Hot Coffee that goes out that continues
4) in the function that realizes cold coffee, Hot Coffee, need to be designed with the two-way water route, select the Hot Coffee water route to lead to the heater heating, select cold coffee water route to heat without heater, but changing device is for the direction in blocking-up water route for one of this intermediate demand, and structural design is relatively complicated.
The utility model content:
The utility model purpose is to solve the shortcoming of above-mentioned prior art, and a kind of electromagnetic type heating coffee machine is provided, and its structure is simpler, can guarantee instant heating, and the efficiency of heating surface is higher.
For reaching above-mentioned purpose, the utility model adopts following technical scheme:
Electromagnetic type heating coffee machine, comprise housing, be provided with the water tank, water pump, heating component and the Switching Power Supply that cooperatively interact in the housing, described heating component comprises: magnetic conduction conductive material water service pipe, be equipped with a coil panel with water service pipe, coil panel produces alternating magnetic field by the control of coil oscillation drive circuit, and the coil oscillation drive circuit is by MCU driving, and single-chip microcomputer is communicated with Switching Power Supply.
Described water service pipe is the disk structure of flexing, and the coil panel that is mated is tray type structure.
Described water service pipe is the helix structure, and the coil panel that is mated is cylinder mode.
Described single-chip microcomputer cooperates Switching Power Supply, cold and hot key switch, discharge monitoring, water pump drive circuit, cooling system, coil oscillation drive circuit and power control circuit, and described power control circuit connects the supply voltage detection and operating current detects.
Described water service pipe is stainless steel tube, and an end is connected with water pump, and the other end is connected with delivery port.
Adopt technique scheme, the utility model electromagnetic type heating coffee machine is to use traditional electromagnetic inductive heating principle to convert electrical energy into heat energy.On circuit, by rectification circuit the alternating voltage of 50/60Hz is become DC voltage, convert DC voltage to high frequency voltage that frequency is 20 ~ 40KHz through control circuit again, the electric current that changes at a high speed flows through coil and can produce the high speed changing magnetic field, the magnetic line of force in magnetic field can produce countless little eddy current by stainless steel tube (magnetic conduction conductive material), makes voluntarily at a high speed heating of stainless steel tube itself.Utilize such principle we with stainless steel waterpipe coiled two schemes, a card, a helix; Then the coil panel coupling is made a card with a cylindrical shape; Two schemes has all been realized the purpose of Electromagnetic Heating.Stainless steel waterpipe is heated when water pump extracts the water of water tank, after water flows to stainless steel waterpipe, become the hot boiling water of 80 degree ~ 95 degree by transient heating, this heating realizes the purpose of instant heating, electromagnetism is just worked when the needs Hot Coffee, can not need work at ordinary times.
