[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0031] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0032] like Figures 1-5 As shown, an electric towel rack with an electromagnetic induction heating and monitoring device includes a towel rack body 1, which is a hollow structure. A heat insulation layer 2 is provided on the inner wall of the towel rack body 1, and an electromagnetic induction coil 3 is provided on the inner wall of the heat insulation layer 2. An electromagnetic radiation detection device is fixedly provided on the back of the towel rack body 1. The towel rack body 1 is made of electromagnetic induction material.

[0033] Furthermore, the towel rack body 1 is bow-shaped, and an electromagnetic induction coil 3 is installed inside the bow-shaped crossbeam 11. The electromagnetic induction coils 3 inside multiple crossbeams 11 are connected in series.

[0034] Furthermore, the number of turns of the electromagnetic induction coil 3 inside the crossbeam 11 from top to bottom gradually increases.

[0035] Furthermore, it also includes a coil carrier 4, the shape of which is adapted to the shape of the inner cavity of the towel rack body 1. A spiral groove 42 is opened on the crossbar 41 of the coil carrier 4 along the length direction, and the electromagnetic induction coil 3 is disposed in the spiral groove 42.

[0036] Furthermore, a groove 43 is formed along the axial direction on the outer circumferential surface of the coil carrier 4, and the groove 43 is connected to the spiral groove 42.

[0037] Furthermore, the coil carrier 4 is made of a non-magnetic polymer material.

[0038] Furthermore, the towel rack body 1 is made of austenitic stainless steel.

[0039] Furthermore, the wall thickness of the towel rack body 1 is 0.5-1mm.

[0040] Furthermore, the towel rack body 1 is fixedly connected to the wall by a connecting plate 5 located on the back of the towel rack body 1.

[0041] Furthermore, it also includes a micro frequency converter 6, which is electrically connected to the electromagnetic induction coil 3 and the power supply respectively. The micro frequency converter 6 is fixedly installed on the wall at intervals from the towel rack body 1.

[0042] The working principle of the above technical solution:

[0043] Electromagnetic induction heating has the advantages of high efficiency and energy saving, rapid heating and strong controllability. Using electromagnetic induction heating for towel racks can also save electricity and reduce waste.

[0044] The towel rack body 1 has a hollow structure, designed in an arc shape, with multiple arc-shaped crossbeams 11, which can be as follows: Figure 1The four crossbeams shown have the following configurations: when the number of crossbeams 11 is even, the open ends of the towel rack body 1 are located on the same side; when the number of crossbeams 11 is odd, the open ends of the towel rack body 1 are located on both sides of the towel rack body. Three to six crossbeams 11 can be installed. A heat insulation layer 2 is fixedly installed inside the towel rack body 1; the heat insulation layer 2 can be a polyurethane coating. An electromagnetic induction coil 3 is placed close to the inner wall of the towel rack body 1 and is electrically connected to an AC power source. After the AC power is switched on, an alternating magnetic field is formed outside the electromagnetic induction coil 3, generating eddy currents inside the towel rack body 1 made of electromagnetic induction material. These eddy currents cause the atoms inside the object to move at high speed and randomly, generating heat energy through collisions and friction between the atoms, thus achieving heating. The towel rack body 1 is preferably made of austenitic stainless steel, which provides good electromagnetic induction heating performance and prevents the towel rack body 1 from rusting. The wall thickness of the towel rack body 1 is 0.5-1mm.

[0045] A plug 7 is provided at the open end of the towel rack body 1. The plug 7 is made of plastic material and is interference-fitted with the towel rack body 1 to prevent moisture from entering the towel rack body 1. The plug 7 of the bottom crossbeam has an axial hole. The wire connecting the electromagnetic induction coil 3 and the micro frequency converter 6 passes through the hole. In order to prevent electromagnetic leakage, a metal plate can be fixed on the end face of the end of the plug that enters the towel rack body 1 to shield the electromagnetic field.

[0046] Since the electromagnetic radiation generated by the electromagnetic field of electromagnetic induction heating can harm the human body, an electromagnetic radiation detection device is fixedly installed on the back of the towel rack body 1. The electromagnetic radiation detection device can be an electromagnetic radiation detector or an electromagnetic radiation alarm. Household electromagnetic radiation detectors and electromagnetic radiation alarms are low in cost and highly sensitive. You can choose a model that is suitable for installation on the back of the towel rack body 1 from the general models on the market as needed. It will not be elaborated here.

[0047] The back of the towel rack body 1 refers to the side of the towel rack body 1 that faces the wall after installation.

[0048] Because the magnetic field strength increases with proximity to the electromagnetic induction coil 3, a coil carrier 4 is installed inside the towel rack body 1 to ensure the outer wall of the towel rack body 1 is as close as possible to the electromagnetic induction coil 3. The shape of the coil carrier 4 is adapted to the shape of the inner cavity of the towel rack body 1. A spiral groove 42 is formed along the length of the crossbar 41 of the coil carrier 4, and the electromagnetic induction coil 3 is placed in the spiral groove 42. A groove 43 is formed along the axial direction on the outer circumference of the coil carrier 4, and the groove 43 communicates with the spiral groove 42. The electromagnetic induction coil 3 is wound in the spiral groove 42, and the connecting wires between the electromagnetic induction coils 3 are placed in the groove 43. Multiple electromagnetic induction coils 3 and connecting wires are connected to the electromagnetic induction coils 3. The conductors between the induction coils 3 are formed by winding the same enameled wire. The conductor inside the enameled wire is copper wire. During manufacturing, the stainless steel plate is first hot-drawn into two bow-shaped semicircles. After the heat insulation layer 2 is sprayed and dried, the coil carrier 4 with the electromagnetic induction coil 3 wound around it is placed in one of the semicircles. Then, the two semicircles are merged and laser-welded. The laser welding has high weld quality and small welding deformation. The towel rack body 1 can maintain its original shape after the welding process. It also has little impact on the heat insulation layer 2 and the coil carrier 4 inside the towel rack body 1, and will not affect the performance of the heat insulation layer 2, the coil carrier 4 and the electromagnetic induction coil.

[0049] The coil carrier 4 is made of a non-magnetic polymer material, such as polyimide (PI), polytetrafluoroethylene (PTFE), or polypropylene (PP).

[0050] The towel rack body 1 is fixedly connected to the wall via a connecting plate 5 on the back of the towel rack body 1. The micro frequency converter 6 is electrically connected to the electromagnetic induction coil 3 and the AC power supply respectively. The micro frequency converter 6 and the towel rack body 1 are fixedly installed on the wall at intervals.

[0051] The number and specific location of the connecting plates 5 can be set as needed, such as... Figure 1 As shown, a total of 3 connecting plates are provided: one is located at the left end of the bottom crossbeam 11 of the towel rack body 1, one is located between the two top crossbeams 11, and one is located between the second and third crossbeams. The specific position of the connecting plate 5 can also be set as needed. The connecting plate 5 can be fixedly connected to the towel rack body 1 or movably connected to the towel rack body 1.

[0052] Miniature frequency converters can adjust the frequency of alternating current and control the temperature of electromagnetic induction heating. Temperature control of electromagnetic induction heating is an existing technology. For example, CN115032892B discloses an electromagnetic induction heating control method and system based on Smith-PID, which can accurately control the heating temperature of electromagnetic induction heating. The electromagnetic heating of the towel rack is controlled at around 55 degrees Celsius.

[0053] The beneficial effects of the above technical solution are as follows:

[0054] The electric towel rack with electromagnetic induction heating and monitoring device described in this utility model has an electromagnetic induction coil installed inside the towel rack body. The towel rack body is made of electromagnetic induction material, and the towel rack body shields the magnetic field of the electromagnetic induction coil within the towel rack body, reducing electromagnetic radiation and preventing harm to the human body. Electromagnetic induction heating is highly efficient and energy-saving, heats up quickly and is highly controllable. Using electromagnetic induction heating in the towel rack can also save electricity and reduce waste.

[0055] In one embodiment, the connecting plate 5 can be fixedly connected to the towel rack body 1, but the distance between the fixedly connected towel rack body 1 and the wall remains unchanged. If the distance is too close, it is inconvenient to take out and put in towels, and if the distance is too far, it will occupy a lot of space. A telescopic device is set between the connecting plate and the towel rack body 1. The telescopic device includes a fixed plate 9 fixedly set in the mounting groove 8 of the connecting plate 5. Two fixed plates 9 are symmetrically arranged vertically. A connecting hole 10 is opened on the fixed plate 9. A vertical shaft 17 is rotatably set in the connecting hole 10. A slide rail 12 is fixedly connected to the vertical shaft 17 between the two upper fixed plates 9. A slide rod 13 is slidably set in the slide rail 12. The end of the slide rod 13 away from the connecting plate 5 is rotatably connected to the towel rack body 1.

[0056] The connecting holes 10 on the two fixing plates 9 are coaxially arranged.

[0057] Both the slide rail 12 and the slide rod 13 are C-shaped. A groove 14 along the length of the slide rail 12 is opened on the upper surface of the lower wall of the slide rail 12. A slider 15 is fixedly installed on the lower surface of the slide rod at a position corresponding to the groove 14. The slider 15 is slidably disposed in the groove 14.

[0058] A shaft hole 16 is provided at the rear of the slide rail 12, and the vertical shaft 17 is inserted into the shaft hole.

[0059] The working principle of the above technical solution:

[0060] To facilitate the retrieval and placement of towels, a telescopic device is installed, such as... Figures 6-9 As shown, the slide rail 12 of the telescopic device is rotatably connected to the connecting plate 5, and the slide rod 13 is rotatably connected to the towel rack body 1. The structure in which the slide rod 13 is rotatably connected to the towel rack body 1 can be set to the same structure as the connection between the slide rail 12 and the connecting plate 5, that is, using a vertically set vertical shaft and a fixed plate to connect the slide rod 13 and the towel rack. Other rotatable connection structures can also be used, which will not be described in detail here.

[0061] When taking or placing towels, pull the towel rack body away from the wall. Due to the telescopic device, the towel rack body 1 is moved away from the wall, and the distance between it and the wall makes it convenient to take or place towels. Then push the towel rack body 1 closer to the wall. When heating or placing towels, it will not take up space.

[0062] During installation, first fix the connecting plate 5 to the wall, then insert the rear end of the slide rail 12 between the two fixing plates 9, aligning the shaft hole 16 with the connecting hole 10. Then insert the vertical shaft 17 into the shaft hole 16 and the connecting hole 10, connecting the connecting plate 5 to the slide rail 12. To prevent the vertical shaft 17 from falling off, a threaded hole can be made on the side wall of the shaft hole 16. After installing the slide rail, screws are screwed into the threaded holes to hold the vertical shaft in place, thus fixing the vertical shaft 17 to the slide rail 12. Then align the slider 15 of the slide rod 13 with the slide groove 14 and push the slide rod 13 into the slide rail 12. To prevent the slide rod 13 from falling off the slide rail, a threaded hole can be made on the bottom surface of the slide groove 14 near the front end of the slide rail 12. After inserting the slide rod 13 into the slide rail 12 and the slider 15 passes through the threaded hole, screw a bolt into the threaded hole to stop the slider 15. The bolt should not be inserted into the slide groove 14 higher than the height of the slide groove 14. After fixing the connecting plates 5 in sequence according to their positions, connect the towel rack body to the slide rod. The connection method is the same as that between the slide rail and the connecting plate, and will not be described again here. Since the slide rail 12 is rotatably connected to the connecting plate 5 and the slide rod 13 is rotatably connected to the towel rack body 1, after pulling the towel rack body 1 away from the wall, the towel rack body 1 can also rotate horizontally about the vertical axis 17, which can move the towel rack body 1 to a suitable position for the user to take out and put in towels.
