Abstract
Description
Technical Field
[0001] This utility model relates to the field of heater technology, specifically to an instantaneous pipeline heater. Background Technology
[0002] Instantaneous pipe heaters are a type of high-efficiency heating equipment that is now widely used in homes. They provide instant heat on demand, eliminating the need for a large water tank required by traditional storage heaters, thus saving electricity and space in daily use.
[0003] Existing instantaneous pipe heaters have certain drawbacks. If a large water flow is maintained for a long time, the water will not heat up in time, the water temperature will drop, and it will not reach the expected water temperature. When the water consumption of the instantaneous pipe heater changes, the water temperature will be unstable, fluctuating between hot and cold, which is inconvenient for people to use. Utility Model Content
[0004] In view of the problems existing in the current instantaneous pipeline heater, this utility model is proposed.
[0005] Therefore, the purpose of this utility model is to provide an instantaneous pipeline heater that solves the problem that the water temperature cannot be kept stable.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An instantaneous pipeline heater includes an inlet pipe and a housing. The inlet pipe is fixedly installed on the top of the housing. A heating chamber is fixedly installed on the inner wall of the housing. A preheating zone is fixedly installed between the housing and the heating chamber. A heating device is fixedly installed on the inner wall of the heating chamber. A stirring paddle is rotatably installed on the inner wall of the heating chamber. One end of the stirring paddle is fixedly connected to the output end of a motor. A connecting pipe is fixedly installed at the bottom of the heating chamber. A first water pump is fixedly installed on the wall of the connecting pipe. An outlet pipe is fixedly installed inside the heating chamber. The outlet pipe extends through the heating chamber to the outside of the housing and is fixedly connected to the housing. A second water pump, a flow sensor, and a temperature sensor are fixedly installed on the wall of the outlet pipe. A return pipe is fixedly installed on the wall of the outlet pipe. A return pump is fixedly installed on the wall of the return pipe. One end of the return pipe is connected to the housing. A descaling device is fixedly installed inside the inlet pipe.
[0008] Preferably, the heating device includes heating rods and a circular tube. The circular tube is fixedly provided on the inner side wall of the heating box, and multiple sets of heating rods are fixedly provided on the tube wall of the circular tube. The tube wall of the circular tube has a circular hole.
[0009] Preferably, the descaling device includes an electromagnetic coil and an exchange resin cylinder. The electromagnetic coil and the exchange resin cylinder are fixedly installed on the inner wall of the water inlet pipe, and the electromagnetic coil is spirally wound around the outer wall of the exchange resin cylinder.
[0010] Preferably, a heat insulation layer is fixedly provided inside the box, and the heat insulation layer is made of rock wool.
[0011] Furthermore, fixing blocks are fixed on both sides of the box body, and threaded holes are opened in the fixing blocks, with bolts threaded in the threaded holes.
[0012] Preferably, a control panel is fixedly provided on one side of the housing.
[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0014] This invention utilizes heat conduction within the heating chamber to preheat the water in the preheating zone. To achieve this preheating, the water flows into the preheating zone before entering the heating chamber when the instantaneous pipe heater is working. During the heating process, the heating rods inside the heating chamber preheat the water in the preheating zone through heat conduction within the heating chamber. This solves the problem of insufficient heating and subsequent water flow failing to reach the specified temperature when a large water flow is maintained for an extended period during use.
[0015] This invention employs a flow sensor and multiple heating rods for precise temperature control. To maintain a stable water temperature regardless of water flow rate, a flow sensor monitors the water flow rate. The heating device uses the water flow rate obtained from the flow sensor and activates several heating rods via a control panel, thus solving the problem of unstable temperature when the water flow changes.
[0016] This invention employs an electromagnetic coil and an ion exchange resin cylinder for descaling. To prevent the accumulation of large amounts of scale in the water pipes after long-term use, which would affect the working efficiency of the instantaneous heater and the quality of the output water, the electromagnetic coil prevents calcium and magnesium ions in the water flowing through the inlet pipe from forming a hard calcite structure. The ion exchange resin cylinder has the characteristic of adsorbing impurities, thus solving the problem of large amounts of scale accumulating inside the instantaneous heater after long-term use, which affects the normal operation of the device.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0025] This utility model provides, for example Figure 1-2The instantaneous pipeline heater shown includes an inlet pipe 1 and a housing 2. The inlet pipe 1 is fixedly installed on the top of the housing 2. A heating chamber 3 is fixedly installed on the inner wall of the housing 2. A preheating zone is fixedly installed between the housing 2 and the heating chamber 3. A heating device is fixedly installed on the inner wall of the heating chamber 3. A stirring paddle 4 is rotatably installed on the inner wall of the heating chamber 3. One end of the stirring paddle 4 is fixedly connected to the output end of a motor 5. A connecting pipe 6 is fixedly installed at the bottom of the heating chamber 3. A first water pump 7 is fixedly installed on the wall of the connecting pipe 6. An outlet pipe 8 is fixedly installed inside the heating chamber 3. The outlet pipe 8 extends through the heating chamber 3 to the outside of the housing 2 and is fixedly connected to the housing 2. A second water pump 9, a flow sensor 10, and a temperature sensor 11 are fixedly installed on the wall of the outlet pipe 8. A return pipe 12 is fixedly installed on the wall of the outlet pipe 8. A return pump 13 is fixedly installed on the wall of the return pipe 12. One end of the return pipe 12 is connected to the housing 2. A descaling device is fixedly installed inside the inlet pipe 1. In operation, water flows into the tank 2 through the descaling device on the inner wall of the inlet pipe 1, which is the preheating zone, to preheat the water. The first water pump 7 delivers the preheated water to the heating tank 3 through the connecting pipe 6, where it is heated by the heating device. During this process, the water is stirred by the stirring paddle 4 driven by the motor 5 to ensure that the water flow is disturbed and that the water is heated evenly. Then, the second water pump 9 delivers the heated water out through the outlet pipe 8 in the heating tank 3, passing through the flow sensor 10 and the temperature sensor 11. If the water temperature reaches the specified temperature, it flows out normally through the outlet pipe 8. If the specified temperature is not reached, the control panel 23 controls the return pump 13 to return the water that has not reached the specified temperature to the tank 2 through the return pipe 12 for reheating and reheating until the water temperature reaches the specified temperature. The return pump 13 and the control panel 23 are electrically connected.
[0026] In order to heat and preheat water, such as Figure 1-3 As shown, the heating device includes heating rods 14 and circular tubes 15. A circular tube 15 is fixedly installed on the inner wall of the heating box 3. Multiple sets of heating rods 14 are fixedly installed on the tube wall of the circular tube 15. A circular hole 16 is opened in the tube wall of the circular tube 15. When in use, water is added into the heating box 3, and the heating rods 14 heat the water in the heating box 3. The heating box 3 can preheat the water in the preheating zone. The circular tube 15 is used to fix the heating rods 14, and the circular hole 16 allows water to flow in and out of the circular tube 15.
[0027] In order to remove limescale as much as possible, such as Figure 1-4As shown, the descaling device includes an electromagnetic coil 17 and an exchange resin cylinder 18. The electromagnetic coil 17 and the exchange resin cylinder 18 are fixedly installed on the inner wall of the water inlet pipe 1. The electromagnetic coil 17 is spirally wound around the outer wall of the exchange resin cylinder 18. During use, water flows into the tank 2 through the water inlet. The electromagnetic coil 17 in the water inlet pipe 1 prevents calcium and magnesium ions in the water from forming a hard calcite structure, and instead generates loose aragonite crystals, which greatly reduces the adhesion of the pipe. At the same time, the exchange resin cylinder 18 has the characteristic of adsorbing impurities and can adsorb other impurities, so that the water entering the tank 2 is kept as pure as possible.
[0028] In order to insulate the motor 5 and the housing 2, such as Figure 1-2 As shown, a heat insulation layer 19 is fixedly installed inside the housing 2. The heat insulation layer 19 is made of rock wool. The heat insulation layer 19 isolates most of the heat generated inside the housing 2, preventing the motor 5 from being in a high-temperature environment, which would affect the normal operation of the motor 5 over time.
[0029] Finally, to facilitate the operation of the fixed housing 2 and heating device, such as... Figure 1-2 As shown, fixing blocks 20 are fixed on both sides of the housing 2. Threaded holes 21 are opened in the fixing blocks 20, and bolts 22 are threaded in the threaded holes 21. A control panel 23 is fixed on one side of the housing 2. The housing 2 is fixed to the wall using bolts 22 through the threaded holes 21. The control panel 23 is electrically connected to the motor 5, the first water pump 7, the second water pump 9, the flow sensor 10, the temperature sensor 11, the reflux pump 13, and the electromagnetic coil 17.
[0030] The housing 2 is fixed to the wall by bolts 22 and threaded connection to the fixing block 20. After the heater is running, when the water flows through the inlet pipe 1, the electromagnetic coil 17 and the ion exchange resin cylinder 18 inside the inlet pipe 1 perform descaling treatment. The electromagnetic coil 17 prevents calcium and magnesium ions in the water from forming a hard calcite structure, instead generating loose aragonite crystals, which greatly reduces the adhesion of the pipe. At the same time, the ion exchange resin cylinder 18 has the characteristic of adsorbing impurities and can adsorb other impurities. Then, the water enters the preheating zone between the housing 2 and the heating box 3. The water is preheated by the heat conduction of the heating box 3. The preheated water enters the heating box 3 through the first water pump 7 and the connecting pipe 6. It is heated by the heating rod 14 and stirred by the stirring paddle 4 driven by the motor 5 to ensure uniform heating. The heating device uses a circular tube 15 with a circular hole 16 to fix multiple sets of heating rods. 14. To achieve efficient heating and prevent the motor 5 from being exposed to high temperatures for extended periods, thus affecting its lifespan, the housing 2 is equipped with a heat insulation layer 19. When heated water flows out through the outlet pipe 8, the flow sensor 10 monitors the water flow. The control panel 23 uses the data returned by the flow sensor 10 to control the heating device to activate several sets of heating rods 14. The temperature sensor 11 detects the water temperature. If the water temperature meets the standard, it flows out normally through the outlet pipe 8. If the water temperature does not meet the standard, the control panel 23 controls the return pump 13 to return the water to the housing 2 through the return pipe 12 for reprocessing. The control panel 23 is electrically connected to the motor 5, the first water pump 7, the second water pump 9, the flow sensor 10, the temperature sensor 11, the return pump 13, and the electromagnetic coil 17. The entire device is centrally controlled through the control panel 23 to ensure stable water temperature output.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
