Description

Technical Field

[0001] The utility model relates to the technical field of heating tubes, in particular to a storage-type electric heating tube. Background Technique

[0002] As a form of traditional water heaters, storage-type electric heating tubes are widely used in households and commercial places. They are favored by many users for their stable heating performance and good usability. The storage-type electric heating tube is the core component of an electric water heater, and its working principle can be divided into several main steps. When the electric water heater is powered on, the heating tube starts to work, converting electrical energy into heat energy to heat the water in the inner tank. During the heating process, the hot water floats upward due to its lower density, while the cold water sinks, forming convection, which makes the water temperature rise evenly. When the water temperature reaches the set temperature, the thermostat will automatically cut off the power, and the heating tube will stop heating. The electric water heater enters the insulation state. The existing storage-type electric heating tubes will form scale due to the deposition of minerals in the water during long-term use at high temperatures. This requires regular removal for cleaning, but the disassembly and cleaning are troublesome. Forgetting to clean for a long time will affect the heating efficiency of the heating tube, resulting in a higher energy consumption problem and difficult maintenance and cleaning. Secondly, long-term high-temperature operation will cause the bonding force of the sealant to decrease, the sealing performance to decrease, and the performance of the insulating material inside the heating tube to decrease, resulting in electric leakage accidents. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is as follows: to provide a storage-type electric heating tube, which magnetizes water through the setting of an electromagnetic component.

[0020] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0021] Next, the present application will be described in detail in conjunction with the accompanying drawings and specific implementation manners.

[0022] As Figures 1-4 shown, a storage water type electric heating tube includes: 1. A storage water type electric heating tube, characterized in that it includes: a connection seat 1, two mounting seats 102 provided at the bottom of the connection seat 1, an electromagnetic box 3 provided at the bottom of the mounting seat 102, two electric heating tubes 4 provided at the bottom of the connection seat 1, an electromagnetic component provided inside the electromagnetic box 3, and the electromagnetic component includes: an iron core 301, an armature 302, a coil 303 and a fixed frame 304; a sealing component provided inside the connection seat 1, and the sealing component includes: a first adhesive layer 202, a second adhesive layer 203, a first rough surface 204 and a second rough surface 205.

[0023] Through the setting of the electromagnetic component, after being powered on, the armature 302 moves, and the magnetic field of the electromagnetic component is stronger. When the water treated by the electromagnetic method is heated, the precipitated calcium carbonate is mainly acicular vaterite crystals with weak adhesiveness and is not easily bonded into hard water scale, preventing the water scale from hanging on the surface of the electric heating tube and affecting heat generation and power consumption. Through the setting of the sealing component, the contact surfaces between the sealing glue and the inner and outer walls of the electric heating tube 4 are uneven, increasing the contact area. After solidification, the bonding strength between the sealing glue and the inner and outer walls of the electric heating tube 4 increases, and the electric heating tube 4 and the sealing glue will not crack during thermal expansion and contraction, nor will it affect the heating layer.

[0024] Among them, a wiring seat 101 is fixedly installed at the top of the connecting seat 1. A plurality of notches 207 are formed inside the connecting seat 1. An insulating head 2 is arranged inside the notch 207. The top of the insulating head 2 is fixedly connected to the wiring seat 101. An electric heating tube lead 201 is arranged inside the insulating head 2. The top of the electric heating tube lead 201 is fixedly connected to the wiring seat 101. The bottom of the electric heating tube lead 201 extends into the electric heating tube 4. A first glue layer 202 is arranged at the bottom of the insulating head 2. The outer side of the bottom of the electric heating tube lead 201, the inner side of the top of the electric heating tube 4, and the bottom of the insulating head 2 are all provided with a first rough surface 204. The surface of the first rough surface 204 is provided with a plurality of triangular tooth-shaped protrusions. The surface of the notch 207 is provided with a second rough surface 205. The outer side of the electric heating tube 4 is provided with a third rough surface 206. A second glue layer 203 is arranged between the second rough surface 205 and the third rough surface 206. The surfaces of the second rough surface 205 and the third rough surface 206 are both provided with a plurality of triangular tooth-shaped protrusions. An electric heating wire 402 is arranged inside the electric heating tube 4. Magnesium oxide powder 401 is filled inside the electric heating tube 4. During assembly, first place the electric heating wire 402 and the electric heating tube lead 201 into the electric heating tube 4, then fill the magnesium oxide powder 401. After filling, fill the sealing glue. The sealing glue fills the first glue layer 202. Since the surface of the first rough surface 204 is uneven, the bonding strength increases after the sealing glue combines with the first rough surface 204 and solidifies. When the heating tube expands and contracts thermally, the bonding surface will not crack, preventing the magnesium oxide powder 401 from leaking. Then, fill the second glue layer 203 with the sealing glue. Since the surfaces of the second rough surface 205 and the third rough surface 206 are uneven, the bonding strength increases after the sealing glue combines with the first rough surface 204 and solidifies, effectively preventing water flow from entering the connecting seat 1 and affecting the insulating head 2.

[0025] Among them, an iron core 301 is fixedly installed at the inner top of the electromagnetic box 3. A fixing frame 304 is fixedly installed on the inner side of the electromagnetic box 3. A coil 303 is fixedly installed on one side of the fixing frame 304. An armature 302 is arranged inside the electromagnetic box 3. The armature 302 penetrates through the bottom of the electromagnetic box 3 and extends to the outside. Two connecting holes 307 are formed at the bottom of the electromagnetic box 3. Two limiting blocks a 305 are fixedly installed on both sides of the bottom of the armature 302. Two limiting blocks b 306 are fixedly installed on both sides of the armature 302. A connecting rod 308 is fixedly installed between the limiting block a 305 and the limiting block b 306. The connecting rod 308 passes through the connecting hole 307.

[0026] After being powered on, an electric current passes through the coil 303, and a magnetic field is generated around the coil 303. The iron core 301 and the armature 302 are magnetized, and an electromagnetic attraction force is generated between them. The armature 302 moves towards the iron core 301, and the connecting rod 308 is driven by the armature 302. Since the limit block a305 is larger than the connecting hole 307, the limit block a305 cannot pass through the connecting hole 307, and the iron core 301 and the armature 302 are combined. The magnetic lines of force are more concentrated, which can enhance the magnetic flux of the entire electromagnetic box 3. The magnetic energy is proportional to the magnetic flux. When the magnetic flux increases, the magnetic energy increases. The magnetic energy magnetizes the water. The calcium carbonate precipitated from the magnetized water when heated is not closely rhombic calcite crystals, but acicular aragonite crystals. The structure of the aragonite crystals is loose, with poor tensile and compressive abilities and weak adhesiveness, and it is not easy to adhere to form hard water scale, and will not adhere to the surface of the electric heating tube, affecting the heat generation and power consumption of the electric heating tube. After power-off, the current in the coil 303 disappears, and the magnetic field generated by the current disappears accordingly. The electromagnetic attraction force between the iron core 301 and the armature 302 disappears, and the armature 302 drops. Since the limit block b306 is larger than the connecting hole 307, the limit block b306 cannot pass through the connecting hole 307, so the armature 302 can be limited to prevent it from falling off.

[0027] Working principle:

[0028] During assembly, the heating wire 402 and the heating tube lead rod 201 are first placed in the heating tube 4, and then the magnesium oxide powder 401 is filled. After the filling, the sealant is filled. The sealant fills the first glue layer 202. Since the surface of the first rough surface 204 is uneven, the sealant and the first rough surface 204 are combined and the bonding strength is increased after solidification. The heating tube expands and contracts with heat, and the bonding surface will not crack, which can effectively prevent the magnesium oxide powder 401 from leaking out. Then, the second glue layer 203 is filled with sealant. Since the surface of the second rough surface 205 and the third rough surface 206 are uneven, the sealant and the first rough surface 204 are combined and the bonding strength is increased after solidification, which can effectively prevent water from entering the connecting seat 1 and affecting the insulating head 2. After power is turned on, the current passes through the coil 303, and a magnetic field is generated around the coil 303. The iron core 301 and the armature 302 are magnetized, and an electromagnetic attraction is generated between the two. The armature 302 moves toward the iron core 301, and the connecting rod 308 is driven by the armature 302. The limit block a305 is larger than the connection hole 307, and the limit block a305 cannot pass through the connection hole 307. The iron core 301 and the armature 302 are combined, and the magnetic lines of force are more concentrated, which can enhance the magnetic flux of the entire electromagnetic box 3. The magnetic energy is proportional to the magnetic flux. The magnetic energy increases with the increase of the magnetic flux. The magnetic energy magnetizes the water. The calcium carbonate precipitated by the magnetized water when heated is not a tightly rhombus calcite crystal, but a needle-shaped aragonite crystal. The structure of the aragonite crystal is loose, and the tensile and compressive resistance is poor. The adhesiveness is poor, and it is not easy to adhere to form hard scale. It will not adhere to the surface of the electric heating tube, affecting the heating and power consumption of the electric heating tube. After power failure, the current in the coil 303 disappears, and the magnetic field generated by the current disappears. The electromagnetic attraction between the iron core 301 and the armature 302 disappears, and the armature 302 falls. Since the limit block b306 is larger than the connecting hole 307, the limit block b306 cannot pass through the connecting hole 307, so it can limit the armature 302 to prevent the armature 302 from falling off.
