[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-6This invention provides a cooling structure for a control system of a multi-purpose electric boiler, including a housing 1, an electric boiler assembly 2 disposed inside the housing 1, a cold water inlet pipe 3 connected to the electric boiler assembly 2, a cold water pipe 91 disposed on the housing 1, a port switching device 4 and a cold water storage tank 92 disposed sequentially between the cold water pipe 91 and the cold water inlet pipe 3, a heat exchange copper plate 5 disposed at one end of the port switching device 4, a diversion cooling water supply pipe 6 disposed inside the heat exchange copper plate 5, the diversion cooling water supply pipe 6 being connected to the port switching device 4, a reciprocating interval drive assembly 7 disposed on the heat exchange copper plate 5 capable of driving the port switching device 4 to reciprocate left and right at intervals, and a heating element mounting base 8 disposed on the heat exchange copper plate 5;

[0028] Working principle: The cold water inlet pipe 3 contacts the cold water that needs to be heated;

[0029] The cold water inlet pipe 3 is connected to the electric boiler assembly 2. When cold water enters the electric boiler assembly 2, the cold water undergoes heat exchange treatment to heat the cold water.

[0030] The heating element mounting base 8 provided on the heat exchange copper plate 5 enables heat transfer.

[0031] The heating component mounting base 8 can be used to install the corresponding device heating component;

[0032] Before entering the cold water inlet pipe 3, the cold water first enters the distribution cooling water pipe 6. The cold water fills the distribution cooling water pipe 6, increasing the distribution area of ​​the cold water. When the heating element works and generates heat, the heat exchange copper plate 5 also generates heat. At this time, the distribution cooling water pipe 6 provides heat dissipation treatment for the heat exchange copper plate 5 over a larger area.

[0033] During the process, the diversion cooling water supply pipe 6 stores cold water, and multiple channels store cold water. The port switching device 4 enables multiple channels to be connected to the cold water input pipe 3 in turn, that is, to drain water into the cold water input pipe 3 in turn. The purpose of this is to ensure that other channels have enough heat exchange time while also ensuring smooth water flow.

[0034] The reciprocating interval drive component 7 can control the port switching device 4 to complete the rotation at equal angles, followed by an intermittent pause.

[0035] The electric boiler assembly 2 includes an electric boiler body 201, on which a water inlet pipe 202 and a drain pipe 203 are provided. A fully immersed electromagnetic heating assembly 204 is provided inside the electric boiler body 201. The water inlet pipe 202 is connected to the cold water input pipe 3. A spiral heat exchange tube 207 is sleeved on the fully immersed electromagnetic heating assembly 204. The electric boiler body 201 is provided with a first drain port 208 and a second drain port 209. The first drain port 208 is used to discharge the sewage inside the fully immersed electromagnetic heating assembly 204, and the second drain port 209 is used to discharge the sewage inside the electric boiler body 201. Its structure is simple, reasonable and ingenious design, which facilitates the discharge of sewage from the fully immersed electromagnetic heating assembly 204 and the electric boiler body 201, and avoids the residue of dirt inside the fully immersed electromagnetic heating assembly 204 and the electric boiler body 201.

[0036] The spiral heat exchange tube 207 includes an inlet pipe 2071 and an outlet pipe 2072 disposed on the electric boiler body 201. The outer wall of the fully immersed electromagnetic heating assembly 204 is provided with a coil 2073, and the two ends of the coil 2073 are respectively connected to the inlet pipe 2071 and the outlet pipe 2072.

[0037] The fully immersed electromagnetic heating component 204 can increase the heat exchange area, thereby improving the heating efficiency and heat exchange area of ​​the water inside the electric boiler body 201.

[0038] The fully immersed electromagnetic heating assembly 204 of the present invention includes a metal heat exchange cylinder 2041, a spiral electromagnetic heating coil 2052 is provided inside the metal heat exchange cylinder 2041, and an electric wire 2053 is provided on the spiral electromagnetic heating coil 2052.

[0039] When the power supply is connected to the power wire 2053, the spiral electromagnetic heating coil 2052 generates electromagnetic induction and works. At this time, the metal heat exchange cylinder 2041 heats up. The metal heat exchange cylinder 2041 has a cylindrical design, and both its inner and outer walls can contact water to achieve a larger heat exchange area.

[0040] The port switching device 4 of the present invention includes a cylindrical valve body 401, an annular sealing plate 402 is provided on the outer sleeve of the cylindrical valve body 401, three through holes 403 are provided at intervals on the outer wall of the annular sealing plate 402, and a water supply hole 404 is provided in the middle of the annular sealing plate 402. The three through holes 403 are connected to the water supply hole 404 in turn.

[0041] The annular sealing plate 402 can be rotated in both directions. Each time the annular sealing plate 402 rotates, the water inlet 404 can connect to one of the three corresponding through holes 403 and one of the three cooling water pipes 601.

[0042] The diversion cooling water supply pipe 6 of the present invention includes three cooling water supply pipes 601 arranged at intervals on the left and right, and the lower ends of the three cooling water supply pipes 601 are connected by an input main pipe 602.

[0043] The reciprocating interval drive assembly 7 of the present invention includes a drive motor 701 disposed on the surface of the heat exchange copper plate 5, a swing rod 702 disposed at the output end of the drive motor 701, a drive shaft 703 disposed at the outer end of the swing rod 702, a bracket 704 disposed in the middle of the heat exchange copper plate 5, a central rotating shaft 705 disposed in the middle of the bracket 704, a rotating disk 706 disposed on the central rotating shaft 705, and four locking slots 707 evenly distributed on the outer circumference of the rotating disk 706. 703 rotates once a week and cooperates with one of the locking ports 707 to drive the rotating disk 706 to rotate 90°. The lower end face of the rotating disk 706 is provided with a lower circular plate 708, and an eccentric shaft 709 is provided on the lower circular plate 708. A side circular plate 710 is provided on one side of the annular closed plate 402, and a drive rod 711 is provided on the side circular plate 710. A straight groove 712 is provided on the drive rod 711, and the eccentric shaft 709 is movably inserted into the straight groove 712.

[0044] The drive motor 701 rotates continuously, and the drive motor 701 drives the swing rod 702 to rotate continuously. After each rotation, the drive shaft 703 can swing 90° and disengage after cooperating with one of the locking ports 707. When the rotating disk 706 completes 90° rotation, it pauses for a period of time to wait for the swing rod 702 to drive the next rotation.

[0045] At this time, the lower circular plate 708 rotates and rotates 90°, which drives the straight groove 712 to swing left and right through the eccentric shaft 709 rotating 90° per revolution.

[0046] The heating component mounting base 8 of the present invention includes a mounting base 801 disposed on the surface of the heat exchange copper plate 5, and the heat exchange copper plate 5 is provided with a plurality of heat dissipation fins 802.

[0047] The rotating disk 706 of the present invention rotates 90° and then drives the annular closed plate 402 to rotate by an angle equal to the interval angle between the two through holes 403.

[0048] The mounting base 801 of the present invention is provided with a device control panel 200.

[0049] When the electric boiler is used to provide hot water, external cold water enters the electric boiler through the cold water pipe 91. The flowing cold water first conducts the heat generated by the control panel 200 during operation to the heat exchange copper plate 5. The heat on the heat exchange copper plate 5 is conducted to the cold water and heats the flowing cold water. After the flowing cold water is heated, it enters the electric boiler assembly 2 through the cold water storage tank 92. This achieves the purpose of recovering the heat generated by the control panel 200 during operation and making effective use of the heat, and also achieves the purpose of water cooling the control panel 200.

[0050] When an electric boiler is used for heating, the electric boiler assembly 2 and the external underfloor heating pipes form a closed heating loop, preventing external cold water from entering the electric boiler. The heat generated by the control panel 200 during operation is conducted to the heat exchange copper plate 5, which in turn conducts heat to the cold water and heats it. Since the cold water storage tank 92 is located above the heat exchange copper plate 5, the heated water rises, while the cold water in the storage tank 92 falls. This creates a hot and cold water exchange system between the cold water storage tank 92 and the branch cooling water supply pipe 6 at the heat exchange copper plate 5, thus achieving the purpose of water-cooling the control panel 200.

[0051] The foregoing has shown and described the basic principles and main features of the present invention, as well as its advantages. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
