Description

Technical Field

[0001] The invention relates to the field of water magnetization, in particular to a water magnetization component and a gas water heater using the water magnetization component. Background Art

[0002] In order to obtain better water quality and avoid scaling in the water pipe, a magnetizing device can be used to magnetize the water. There are usually two types of existing magnetizing devices, one using a permanent magnet and the other using an electromagnet.

[0003] When an electromagnet is used, the coil will generate heat when energized. If the temperature rise is too large, it will not only affect the magnetization effect, but also affect the service life of the magnetization device when used for a long time. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a water magnetization component with good heat dissipation in view of the current status of the prior art, so as to ensure the magnetization effect and the service life of the magnetization component.

[0005] Another technical problem to be solved by the present invention is to provide a gas water heater with good magnetization effect and long service life of magnetization components in view of the current status of the prior art.

[0006] The technical solution adopted by the present invention to solve the above technical problems is: the water magnetization component includes a water pipe and a magnetization component arranged outside the water pipe, characterized in that:

[0007] The magnetization component includes a shell that is sleeved outside the water pipe, and the inner cavity of the shell is connected to the external environment of the shell; at least two electromagnets are arranged between the water pipe and the shell, and each of the electromagnets is arranged at intervals along the circumference of the water pipe; the gap between adjacent electromagnets forms an airflow channel.

[0008] Preferably, the water pipe is made of flexible material;

[0009] A memory alloy spring is arranged in the air flow channel; when heated, the memory alloy spring stretches and contacts the wall of the water pipe, squeezing the water pipe to cause radial deformation, and the memory alloy spring releases the squeezing of the water pipe in the restored contracted state.

[0010] Preferably, the memory alloy spring is made of CuZnAl shape memory alloy; CuZnAl shape memory alloy reaches an optimal phase transition temperature at about 60°C, which is exactly the temperature when the coil is supplied with a working voltage of 3V.

[0011] As a further improvement, a frame may be provided in the air flow channel, and a connecting plate may be provided on the side wall of the frame; the memory alloy spring is accommodated in the frame; and the two ends of the connecting plate are respectively in contact with the frame and the memory alloy spring;

[0012] The frame and the connecting plate are made of heat-conducting materials. Preferably, they are made of highly efficient heat-conducting materials with good elasticity, such as copper, so that heat can be quickly transferred to the memory alloy spring. Preferably, the frame and the connecting plate are integrally formed.

[0013] The water pipe is made of silica gel, and the thickness of the water pipe is 0.5-1 mm;

[0014] A support frame is arranged inside the water pipe; the support frame includes support rings at both ends and connecting rods connected between the two support rings, and there are at least two connecting rods arranged at intervals to ensure that the inner walls of the water pipe will not stick together.

[0015] The shell is a tubular structure, and an end cover is connected between the two ports of the shell and the outer wall of the water pipe. The end cover is provided with through holes corresponding to each of the air flow channels.

[0016] Preferably, each of the electromagnets can be arranged in a closed cover, preferably the cover is close to the inner wall of the shell, so as to effectively reduce magnetic leakage, reduce air gap, increase the magnetic field strength inside the water pipe and enhance the heat dissipation of the coil.

[0017] The electromagnet comprises an iron core and a coil wound around the iron core; the iron core and the cover body are integrally formed.

[0018] Preferably, the cover body and the iron core are made of silicon steel.

[0019] The gas water heater using the above-mentioned magnetized component is characterized in that the water pipe is connected to the water outlet pipe of the water heater, the magnetized component is arranged near the lower part of the water heater shell, and an air inlet is arranged on the bottom surface of the shell; a fan is arranged in the shell; and the fan is located above the magnetized component.

[0020] Furthermore, the coil can be connected to the control system of the gas water heater, and the voltage can be adjusted in real time in combination with the flow information provided by the water flow sensor in the gas water heater. The corresponding appropriate magnetic field strength can be matched according to the flow size. When the water flow increases, the coil voltage increases, and the magnetic field strength and heat generation will increase; the increase in magnetic field strength can ensure the magnetization effect under large water volume conditions; when the heat generation increases, the memory alloy spring stretches, the ventilation area increases, and the heat dissipation is enhanced; this design can both ensure the magnetization effect and enhance the heat dissipation.

[0021] The magnetization of water quality can be carried out more fully and effectively.

[0022] Compared with the prior art, the water magnetization assembly provided by the present invention has the following advantages:

[0023] 1. The energized coil around the water pipe can stimulate a magnetic field, which can magnetize the water in the water pipe, and the magnetization effect is good, effectively avoiding the formation of scale in the water pipe;

[0024] 2. The memory alloy spring is set so that when the coil temperature rises, the memory alloy spring deforms and pushes the flexible water pipe inward, increasing the width of the air flow channel, making the heat dissipation area larger, reducing the diameter of the water pipe, and accelerating the water flow speed in the water pipe, taking away the heat more quickly; thereby effectively dissipating heat to prevent the inner wall temperature from being too high to affect the magnetization effect and damage the coil, thereby extending the service life of the water magnetization component.

[0025] 3. For gas water heaters that use water magnetization components, the magnetization components are set at the position of the water outlet pipe close to the bottom of the shell. The fan in the gas water heater is used to quickly remove the heat in the cooling channel, and the heat dissipation efficiency is higher. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention is further described in detail below with reference to the accompanying drawings.

[0031] Example 1

[0032] like Figures 1 to 3 As shown, the water magnetization assembly includes:

[0033] The water pipe 1 is made of flexible material and is sleeved outside the support frame 5. The water pipe in this embodiment is made of silicone with a thickness of 1 mm. The thickness of the water pipe can be between 0.5 and 1 mm to ensure that the diameter of the water pipe can be deformed under external force.

[0034] The support frame 5 includes support rings 51 at both ends and connecting rods 52 connected between the two support rings 51 . There are at least two connecting rods 52 , which are arranged at intervals.

[0035] The magnetizing component is used for magnetizing the water flowing through the water pipe 1, and comprises a shell 2 sleeved outside the water pipe 1, a cover 33, an electromagnet 3 and a memory alloy spring 4.

[0036] The shell 2 is a tubular structure, and an end cap 22 is connected between the two ends of the shell 2 and the outer wall of the water pipe. The end cap 22 is provided with through holes 21 corresponding to each air flow channel 34. Four through holes are provided in this embodiment. The inner cavity of the shell is connected to the external environment of the shell through each through hole.

[0037] The electromagnet 3 is arranged in a cover body 33, which is arranged in the shell 2 and abuts against the inner circumferential wall of the shell, and includes an iron core 31 and a coil 32 wound on the iron core 31. In this embodiment, four electromagnets 3 are arranged outside the water pipe 1 and are arranged at intervals in the cavity between the cover body 33 and the water pipe 1. The cavity between adjacent electromagnets forms an air flow channel 34. The cover body can be tubular; it can also be a tubular structure with an end face. The end face of the cover body 33 is provided with through holes that are compatible with each through hole, and each air flow channel is connected to the four through holes 21 respectively.

[0038] In this embodiment, the iron core 31 and the cover body 33 are integrally formed and made of silicon steel.

[0039] The memory alloy spring 4 is arranged in the air flow channel 34 and can deform with the change of temperature. When heated, the memory alloy spring 4 stretches and can contact the wall of the water pipe, squeezing the water pipe to cause radial deformation. The memory alloy spring retracts in the restored contracted state, that is, in the free state, to release the squeezing of the water pipe.

[0040] The memory alloy spring in this embodiment is made of CuZnAl memory alloy.

[0041] The frame 41 is arranged in the air flow channel 34, and is used to accommodate the memory alloy spring and conduct the heat in the surrounding environment to the memory alloy spring 4; the memory alloy spring 4 is accommodated in the frame 41; a connecting plate 42 is also arranged in the frame 41, and the two ends of the connecting plate 42 respectively contact the frame 41 and the memory alloy spring 4. The frame and the connecting plate in this embodiment are integrally formed, and are both made of heat-conducting material copper.

[0042] When water flows into the water pipe, the coil is energized to generate a magnetic field. The hot water flows through the water pipe and is magnetized by the magnetic field evenly arranged in the water pipe, thus achieving water magnetization. Part of the heat generated by the coil channel is carried away by the water flowing in the water pipe, and part is dissipated from the air flow channel to the surrounding environment through the through hole. As the coil heats up, the temperature rises, the memory alloy spring senses part of the heat itself, and the frame also conducts the heat in the surrounding environment to the memory alloy spring; the memory alloy spring undergoes phase change and elongation, the water pipe is squeezed and deformed, the water pipe diameter becomes smaller, the air flow channel becomes wider, the heat dissipation in the air flow channel is unobstructed, and the air cooling speed is accelerated; secondly, the inner diameter of the water pipe becomes smaller, the water flow speed is accelerated, and the water flow speed becomes faster. The water-cooled and air-cooled dual cooling chambers, the high-efficiency copper heat conductive sheet, and the shape memory alloy spring as a strain medium, the water magnetization device can achieve efficient magnetization while also achieving efficient heat dissipation, greatly reducing the risk of serious heating of the coil and burning, and effectively extending the service life of the device.

[0043] Example 2

[0044] This embodiment is an application example of Embodiment 1, in which the water magnetization component in Embodiment 1 is applied to a gas water heater.

[0045] like Figure 4 As shown, the water pipe 1 is connected to the water outlet pipe 61 of the gas water heater, the magnetization component is arranged near the lower part of the water heater shell 62, and an air inlet 64 is arranged on the bottom surface of the shell 62; a fan 63 is arranged in the shell 62; the fan 63 is located above the magnetization component.

[0046] When the gas water heater is working, the water flows through the magnetizing component and is magnetized. Under the action of the fan of the gas water heater, the cold air outside the shell enters the shell from each air inlet, and part of the air enters the air flow channel through the through holes and flows out from the through holes on the other end face of the shell. The air cooling speed is accelerated, and the heat generated by the coil channel is quickly taken away, resulting in a better cooling effect.

[0047] The rest of the contents are the same as those in Example 1.
