The drinking water machine comprises a shell, a bottle holder, a bucket and a heating body; the heating body comprises a high-frequency induction coil panel as well as an upper metal coil pipe and a lower metal coil pipe which are arranged at the upper side and the lower side of the coil panel, the metal panel is flat, the length of the short side of the section of the inner cavity of the metal panel is 3.0-4.0 mm, and the length of the long side of the section of the inner cavity of the metal panel is 15-30mm; the water feeding end of the lower metal coil pipe is connected with the bucket at the bottom of the bottleholder through a passage water pipe, the water discharging end of the lower metal coil pipe is connected with the water feeding end of the upper metal coil pipe, and the water discharging end of the upper metal coil pipe is connected with a water outlet arranged outside the shell through an electromagnetic valve; the surface of the shell is provided with an electrified switch of the heating body,and the electrified switch is connected with the electromagnetic valve. The drinking water machine provided by the invention has the advantages of rapid rise of temperature, reasonable structure, simple manufacture process and particularly high thermal efficiency, can obtain hot water according with the drinking requirement in short time, and is a novel drinking water machine which can be completely implemented and popularized and accord with the development tread of endowment protection and energy saving.

Description

technical field [0001] The present invention relates to a water dispenser, in particular to an instant hot water dispenser which can instantly provide hot water for drinking without pre-stored hot water in the machine, and more particularly relates to an instant drinking water dispenser which utilizes electromagnetic induction to instantly provide the required drinking water. Electromagnetic instant hot water dispenser for hot water. Background technique [0002] Drinking water dispenser is a kind of device that people usually use and can provide drinking water conveniently. Ordinary water dispensers are usually composed of a shell, a bottle seat located on the upper part of the shell, a heating system located in the shell, normal temperature water and hot water outlets, normal temperature water and hot water discharge valves, etc.; , the hot water heated to a predetermined temperature is stored in the heat tank, which can be taken at any time. Due to the limitation of the...

Problems solved by technology

Since the water dispenser adopts electric heating, even if the heating layer is provided with a heat insulating layer, there is still more or less heat loss in the process of heat transfer; in addition, the heating layer of the electric heating wire needs to pass through the insulating heat conducting layer The heat is transferred to the metal tube, the thermal resistance is large, and the efficiency is low

[0003] Chinese invention patent 200720066139.1 discloses an electromagnetic heating system for water dispensers. The system wraps ceramic or quartz insulating materials on the outer wall of a stainless steel tube, and then winds high-frequency electromagnetic coils on the ceramic or quartz insulating materials. The principle of electromagnetic induction is to heat the water in the stainless steel pipe. This patent is theoretically feasible, but it cannot be implemented. This is because the time for water to flow through the water pipe is relatively short. To raise the water from normal temperature to a drinking temperature, it must be compared Long pipeline, so the stainless steel pipe in the machine must be very long, coupled with the winding insulation material and high-frequency electromagnetic coil, it will inevitably cause the volume of the water dispenser to be very large, which is very impractical

In addition, only one side of the magnetic field generated by the high-frequency electromagnetic coil is used, and the other side is not only wasted, but also generates magnetic radiation. The process of winding the high-frequency electromagnetic coil outside the metal tube is also very troublesome and complicated.
