Detailed Implementation

[0027] like Figures 1-24The following describes an electromagnetic heating water dispenser: It includes a lid 1, an outer shell 2, a main control circuit board 3, a function operation controller 4, an electromagnetic heating generator 5, a non-magnetized inner liner 6, a magnetic ring device for the inner liner 7, and an electric water dispensing device 8. The non-magnetized inner liner 6 is made of glass or ceramic. The outer shell 2 has a cylindrical rotating body around its circumference. The interior of the outer shell 2 is a cavity 201 for housing electrical components and the non-magnetized inner liner 6. The top of the non-magnetized inner liner 6 has an open spout 61, which is designed to hold water. The top of the outer shell 2 has a through-hole spout 202 for adding water. The non-magnetized inner liner 6 is fixedly installed in the inner cavity 201 of the outer shell 2. The walls of the spout 61 and the spout 202 are connected. The bodies are tightly connected, fixed, and sealed to prevent the non-magnetic inner liner 6 from loosening. For example, they are sealed with silicone sealing rings or adhesive. The lid 1 can be opened to fit the kettle shell opening 202 and / or the inner liner opening 61. That is, the lid 1 can be opened to fit the kettle shell opening 202, or the kettle shell opening 61, or the lid 1 can be opened to fit the common body of the kettle shell opening 202 and the inner liner opening 61. All three types of lid-fitting connections are possible and belong to the existing connection structure, and are not limited to them. The connection structure is as follows: A main control circuit board 3 is fixed to the bottom of the inner cavity 201 with screws. The main control circuit board 3 is connected to the function operation controller 4, the electromagnetic heating generator 5, and the electric water outlet device 8 via wires. Function selection is achieved by manually pressing the function buttons on the function operation controller 4. The main control circuit board 3 receives signals from the function operation controller 4 and executes the operation. The operation of the electromagnetic heating generator 5 and the electric water outlet device 8 is controlled by pressing the function buttons on the function operation controller 4. The main technical improvement of this product is that the electromagnetic heating generator 5 is fixed in a ring around the lower outer section of the non-magnetized inner liner 6. A magnetic ring device 7 is provided on the lower inner wall of the non-magnetized inner liner 6. The magnetic ring device 7 is detachably and tightly connected to the inner wall of the non-magnetized inner liner 6. The magnetic ring device 7 is inserted into the non-magnetized inner liner 6 through the shell opening 202 and the inner liner opening 61. When the magnetic ring device 7 becomes dirty, it is easily removed for cleaning and then reinserted.During operation, the main control circuit board 3 controls the electromagnetic heating generator 5 to work and generate an alternating magnetic field. The magnetic field lines penetrate the non-magnetized inner liner 6. When the electromagnetic heating generator 5 is energized and works in coordination with the magnetized inner liner ring device 7, the electromagnetic heating generator 5 and the magnetized inner liner ring device 7 cut these alternating magnetic field lines, thereby generating an alternating current in the metal iron part of the magnetized inner liner ring device 7. This current is called an eddy current. The eddy current causes the metal iron molecules of the magnetized inner liner ring device 7 to move at high speed and randomly. These moving molecules collide and rub against each other. This generates heat energy, rapidly heating the water inside the non-magnetized inner tank 6. The water is then heated via the magnetic ring device 7 within the inner tank. Electromagnetic heating efficiency is extremely high, reaching up to 95%, because it directly converts electrical energy into heat energy without relying on heat conduction or radiation. The magnetic lines of force generated during operation do not generate heat with the non-magnetized inner tank 6, nor does it utilize the inner tank 6 for heat transfer. Therefore, the inner wall of the non-magnetized inner tank 6 will not scorch or dry-burn, and scale will not adhere to it, making cleaning difficult. Furthermore, the water remains relatively stable during and after the heating and curing process. Scale will adhere to the bottom of the non-magnetic inner tank 6, at most settling existing impurities in the water, which are easy to clean. The ceramic and glass non-magnetic inner tank 6 has good anti-scorching, anti-dry burning, and anti-scale adhesion effects. The non-magnetic inner tank 6 does not interfere with the electromagnetic field. The surround heating design provides a large overall heating area and high water heating efficiency. The outer wall of the outer shell 2 has a protruding and fixed functional operation controller 4, which is a rigid suspension connection. An electric water outlet device 8 is connected between the functional operation controller 4 and the bottom of the non-magnetic inner tank 6. The electric water outlet device 8 is arranged in the shell cavity 20. 1. The water outlet of the electric water dispensing device 8 is located at the bottom of the function operation controller 4. In use, after starting the pumping operation via the function operation controller 4, the main control circuit board 3 controls the electric water dispensing device 8 to draw water from the non-magnetically controlled inner tank 6. The water flows out from the water outlet at the bottom of the function operation controller 4. A water cup can be placed below the water outlet to collect the water. The water outlet of the electric water dispensing device 8 utilizes the space of the function operation controller 4, eliminating the need for separate installations. This simplifies the design of the water outlet structure, reduces structural complexity, facilitates assembly, and results in a cleaner product appearance. This electromagnetic heating water dispenser is a storage-type heating system. By setting the heating time, the water is thoroughly heated for healthier drinking. After heating, it maintains a constant temperature, ensuring hot water is always available.

[0028] Preferably, the upper outer wall of the outer shell 2 has a shell wall hole 203. A function operation controller 4 is protruding and fixed to the opening of the shell wall hole 203 by means of snap-fit, screws, or plug-in. The function operation controller 4 includes a bottom shell 41, a control board bracket 42, a function operation control circuit board 43, and a top shell 44. A water tap hole 45 is provided at the bottom of the bottom shell 41. The control board bracket 42 is stacked inside the bottom shell 41 and fixed with screws. The function operation control circuit board 43 is fixed to the top of the control board bracket 42 by screws. The function operation control circuit board 43 is connected to the main control circuit board 3 via a wire passing through the shell wall hole 203. The top shell 44 is disposed above the function operation control circuit board 43, and the top shell 44 covers the top of the bottom shell 41 and is fixedly connected by screws. The top shell 44 and the bottom shell 41 cover the control board bracket 4. 2. The function operation control circuit board 43 is enclosed; the control board bracket 42 is integrally molded, belonging to the shell cover type, which isolates / separates the function operation control circuit board 43 from the water outlet section of the electric water outlet device 8 through a partition layer for water and electricity isolation / separation function; the above is a further detailed structure of the function operation controller 4; the bottom shell 41 and the control board bracket 42 are integrally injection molded; the top shell 44 is integrally molded and is made of LCD panel or plastic. Several function operation resistive touch buttons are welded and fixed to the surface of the function operation control circuit board 43. The function operation resistive touch buttons are connected to the reverse side of the top shell 44. Function contact text, such as: on / off, heating, water pumping, etc., or operation button symbols are pasted or screen-printed on the outer top of the top shell 44; the function operation is realized by pressing / contacting the corresponding function button. Alternatively: the top shell 44 can also have several button holes to install touch buttons, and function button stickers can be pasted on the surface to realize function operation.

[0029] The electric water outlet device 8 includes a water outlet hole 81 at the bottom of the non-magnetic inner tank 6, a first water outlet pipe 82, an electric water pump 83, and a second water outlet pipe 84. The first water outlet pipe 82 and the second water outlet pipe 84 are soft rubber tubes.

The other end of the first water outlet pipe 82 is inserted into and sealed to the water inlet connector of the electric water pump 83. The water outlet connector of the electric water pump 83 is inserted into and sealed to the second water outlet pipe 84. The second water outlet pipe 84 passes through the shell wall hole 203. The end of the second water outlet pipe 84 is inserted into the inner bottom of the bottom shell 41. The end of the second water outlet pipe 84 is separated from the functional operation control circuit board 43 by the control board bracket 42 to achieve water and electricity separation. The end of the second water outlet pipe 84 is fixed at the water nozzle hole 45. The second water outlet fitting 84 utilizes the space of the bottom shell 41 and achieves water and electricity separation through the control board bracket 42, which facilitates the setting of the water outlet structure. This allows users to operate the function operation controller 4 while also placing a water cup below the function operation controller 4 to collect water.

[0030] Preferably, another structure of the second water outlet fitting 84: The second water outlet fitting 84 includes a front hose and a rigid plastic water outlet. The water outlet connector of the electric water pump 83 is inserted into and sealed to the front end of the front hose and the rear end of the front hose is inserted into and sealed to the top of the rigid plastic water outlet. Water exits from the lower end of the rigid plastic water outlet. The rigid plastic water outlet is vertically fixed to the water outlet hole 45 by snap-fit, screws or adhesive, in order to fix the rigid plastic water outlet in place and provide a firm installation of the rigid plastic water outlet.

[0031] Preferably: the lower section of the non-magnetized inner liner 6 is a vertical cylindrical shape with equal diameter; the electromagnetic heating device 5 includes a heat-insulating base plate 51, a plastic cylinder 52, an upper ring frame 53, a magnetic induction coil 54, and several magnetic rods 55; the heat-insulating base plate 51, the plastic cylinder 52, and the upper ring frame 53 form a magnetic induction coil support; a water level sensor is mounted on the top or inner wall of the magnetic induction coil support by screws or clamps, and the water level sensor is connected to the main controller 3 by wires. The water level sensor is used to detect the minimum water level of the non-magnetized inner liner. The main controller 3 sets a minimum water level value program. When the water level sensor detects that the water level is lower than the set water level value, the main controller 3 will control the magnetic induction coil 54 to cut off the power and stop heating to prevent burning, dry burning, etc.; the plastic cylinder 52 is used to wind the magnetic induction coil 54 and has a heat insulation function; the heat-insulating base plate 51 is fixed to the bottom of the shell cavity 201 by screw assembly; the heat-insulating base plate 51 and the upper ring frame 53 form a... A magnetic induction coil 54 is wound around a groove. The interior of the plastic cylinder 52 is an open cavity 521. The lower section of the non-magnetized inner liner 6 is inserted into the cavity 521 and fixed. The magnetic induction coil 54 is also wrapped around the outside of the lower section of the non-magnetized inner liner 6. The plastic cylinder 52 is vertically fixed above the middle of the heat insulation base plate 51. The upper ring frame 53 is fixedly connected to the top outer wall of the plastic cylinder 52. The heat insulation base plate 51, the plastic cylinder 52, and the upper ring frame 53 are all connected together. The entire assembly is injection molded in one piece. A magnetic coil 54 is tightly attached to the outer wall of the plastic cylinder 52. Several magnetic rods 55 are evenly distributed and vertically fixed to the outer wall of the magnetic coil 54, with the rods tightly attached to the coil. The magnetic rods 55 are fixed between the heat-insulating base plate 51 and the upper ring frame 53. Preferably, the heat-insulating base plate 51 has rod insertion holes, and the upper ring frame 53 has a locking slot on its reverse side. The bottom end of the magnetic rod 55 is inserted into the rod insertion hole for fixation, and the top end is inserted into the locking slot for fixation. The magnetic coil 54 is connected to the main control circuit board 3 via wires.

[0032] The inner liner magnetic ring device 7 is a magnetized stainless steel thin ring mesh 71. The magnetized stainless steel thin ring mesh 71 is detachably attached to the lower inner wall of the non-magnetized inner liner 6, corresponding to the inner and outer sides of the magnetic coil 54. The magnetic rod 55 is used to drive the magnetic lines of force inward to the center, making the magnetic lines of force longer and denser, so that the magnetized stainless steel thin ring mesh 71 receives more magnetic potential / magnetic intensity, thereby improving heating efficiency and reducing the outward diffusion of magnetic lines of force and reducing external magnetic radiation.

[0033] When the magnetized stainless steel thin ring mesh 71 is dirty, it can be removed for cleaning, and then put back in.

[0034] During operation, after the magnetic coil 54 is energized, it works in conjunction with the magnetic rod 55 and the magnetized stainless steel thin ring mesh 71 to generate magnetic lines of force. These alternating magnetic lines of force cut each other, generating an alternating current in the ferrous metal portion of the magnetized stainless steel thin ring mesh 71. This current is called an eddy current. The eddy current causes the iron molecules in the magnetized stainless steel thin ring mesh 71 to move at high speed and randomly. These moving molecules collide and rub against each other, generating heat energy, which rapidly heats the water inside the non-magnetized inner tank 6. The water is heated through the magnetized stainless steel thin ring mesh 71. The mesh size of the magnetized stainless steel thin ring mesh 71 increases the water immersion area and the formation of eddy currents. The larger area of ​​the magnetized stainless steel thin ring mesh 71 allows for the generation of more magnetic lines of force / magnetic fields. The eddy currents generated by the mesh and the electromagnetic field / magnetic lines of force are more intense, resulting in better heating and improved heating efficiency. The aforementioned electromagnetic heating method has a wide heating area and high heating efficiency. Magnetized stainless steel thin ring mesh 71 is relatively common, easy to process, and low in cost.

[0035] The magnetic coil 54 is an excitation coil assembly. When the main control circuit board 3 provides a high-frequency alternating current to the excitation coil assembly, the excitation coil assembly generates an alternating magnetic field. The magnetic lines of force are absorbed by the iron-containing magnetized stainless steel thin ring mesh 71. Under the electromagnetic effect of the excitation coil assembly, the iron-containing magnetized stainless steel thin ring mesh 71 forms internal eddy currents and generates heat.

[0036] Preferably, the upper section of the non-magnetic inner liner 6 is an enlarged diameter cylinder to increase water capacity. The diameter of the upper section of the non-magnetic inner liner 6 is larger than that of the lower section. The lower section of the non-magnetic inner liner 6 is designed to be smaller in diameter to accommodate the electromagnetic heating device 5.

The upper inner liner support 56 stabilizes the outer shell 2. While protecting and stabilizing the non-magnetic inner liner 6, the upper inner liner support 56 also provides support and stability for the heat insulation base plate 51, the plastic cylinder 52, and the upper ring frame 53.

[0037] Preferably, the main control circuit board 3 is arranged below the heat-insulating base plate 51, and the top of the main control circuit board 3 is fixed with a heat-insulating and waterproof cover 31 by screws, which provides heat insulation and waterproofing between it and the non-magnetic inner liner 6; a cooling fan 32 is arranged below the main control circuit board 3, and the cooling fan 32 is fixedly connected to the bottom aluminum heat sink of the main control circuit board 3, and the cooling fan 32 is connected to the main control circuit board 3 by wires; a heat dissipation ventilation hole 204 is opened at the bottom of the outer shell 2; when heating, the cooling fan 32 works, and air circulation and heat dissipation are carried out through the heat dissipation ventilation hole 204 to prevent the internal temperature from getting too high and to protect the electrical components.
