Technical Field
[0001] This utility model relates to the field of water heater technology, specifically to a water heater with ultraviolet sterilization. Background Technology
[0002] Electric water heaters are water heaters that use electricity as an energy source for heating. They are one of the three major types of water heaters, along with gas water heaters and solar water heaters. Electric water heaters can be divided into three types according to their heating power: storage type (also known as volumetric or thermal storage type), instant type, and quick-heating type (also known as semi-storage type). Water may contain some bacteria, so sterilization components are needed to disinfect them and improve water quality.
[0003] Existing ultraviolet (UV) sterilization water heaters typically have the UV sterilizer fixedly installed inside the heater. The UV light irradiates the water to sterilize it. However, the fixed installation makes installation and disassembly inconvenient, and the high temperature inside the heater can easily damage the sterilizer, reducing its lifespan. Therefore, we need to propose a UV sterilization water heater. Utility Model Content
[0004] The purpose of this invention is to provide a water heater with ultraviolet sterilization. Water flows into the inlet pipe through a cold water connection valve, and then enters the heater for heating. The heated water then flows through the outlet pipe into the sterilizer for sterilization. Finally, the water flows into the main hot water pipe through a hot water connection valve, and the hot water is discharged to a designated location for use. By installing the sterilizer between the outlet pipe and the hot water connection valve using a first flange and a second flange, the sterilizer is effectively installed outside the heater. This facilitates maintenance and replacement of the sterilizer. Furthermore, placing the sterilizer outside the heater accelerates heat dissipation and cooling, extending its service life and solving the problems mentioned in the background art.

The drain end of the second flange is connected to a hot water connection valve. The drain end of the hot water connection valve is connected to the main hot water pipe.
[0006] Preferably, the sterilizer includes a fixed protective cover, with a water pipe installed through the inside of the protective cover. The two ends of the water pipe are respectively connected to a first flange and a second flange through a set of sealing rings.
[0007] Preferably, the protective cover has several sets of mating holes at both the upper and lower ends, and the protective cover is bolted and fixed to the first flange and the second flange through the mating holes.
[0008] Preferably, a cavity is formed between the side wall of the protective cover and the outer side of the water pipe. Two sets of conductive rings are symmetrically installed inside the cavity, and several sets of ultraviolet lamps are electrically installed on opposite sides of the two sets of conductive rings.
[0009] Preferably, a number of heat dissipation fins are fixedly installed on the outer arc surface of the protective cover, and the heat dissipation fins are evenly distributed vertically on the outer side of the protective cover.
[0010] Preferably, a control panel is installed on one side of the heater, and the control panel is electrically connected to one end of the power control board via a circuit.
[0011] Preferably, a set of temperature sensors is installed through the middle of both the cold water connection valve and the hot water connection valve, and both sets of temperature sensors and the water flow sensor are electrically connected to one end of the power control board through a circuit.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4 This utility model provides a water heater with ultraviolet sterilization, including a heating component 1 and a power control board 10. The heating component 1 includes a heater 11. The bottom of the heater 11 is connected to an inlet pipe 13 and an outlet pipe 14. One end of the inlet pipe 13 is connected to a water flow sensor 2. The inlet end of the water flow sensor 2 is connected to the main water supply pipe through a cold water connection valve 3. The outlet end of the outlet pipe 14 is connected to a first flange 4. The outlet end of the first flange 4 is connected to a sterilizer 5 by bolt sealing. The outlet end of the sterilizer 5 is connected to a second flange 6. The outlet end of the second flange 6 is connected to a hot water connection valve 8. The outlet end of the hot water connection valve 8 is connected to the main hot water pipe.
[0022] In use, through the setup of heating component 1 and power control board 10, power control board 10 provides electrical energy to heater 11 and can control the start and stop of heater 11. Water flows through cold water connection valve 3 and water flow sensor 2 into the interior of water inlet pipe 13, and finally the water enters the interior of heater 11 for heating, thereby achieving the effect of heating water. Water flow sensor 2 can monitor water volume and flow rate, which facilitates the adjustment of heater 11 and avoids the heater 11 from dry burning and causing equipment damage. The heated water... The water enters the sterilizer 5 through the outlet pipe 14, thereby achieving the effect of sterilizing the water. Finally, the water flows into the main hot water pipe through the hot water connection valve 8, and the hot water is discharged to the designated location for use through the hot water boiling pipe. By installing the sterilizer 5 between the outlet pipe 14 and the hot water connection valve 8 through the first flange 4 and the second flange 6, the sterilizer 5 is installed outside the heater 11, which facilitates the maintenance and replacement of the sterilizer 5. At the same time, placing the sterilizer 5 outside the heater 11 can accelerate the heat dissipation and cooling speed.
[0023] The sterilizer 5 includes a fixed protective cover 51. A water pipe 53 is installed through the inside of the protective cover 51. Both ends of the water pipe 53 are connected to the first flange 4 and the second flange 6 through a set of sealing rings 7. The water pipe 53 is made of light-transmitting material to allow ultraviolet light to irradiate the water inside the water pipe 53. The water pipe 53 is squeezed and connected to the flange to achieve the effect of water flow.
[0024] The protective cover 51 has several sets of docking holes 52 at both the top and bottom. The protective cover 51 is bolted to the first flange 4 and the second flange 6 through the docking holes 52. The docking holes 52 facilitate the quick docking between the protective cover 51 and the first flange 4 and the second flange 6, thereby achieving the effect of quick installation and disassembly of the sterilizer 5, and facilitating the maintenance and replacement of the sterilizer 5.
[0025] A cavity 54 is formed between the side wall of the protective cover 51 and the outer side of the water pipe 53. Two sets of conductive rings 55 are symmetrically installed inside the cavity 54. Several sets of ultraviolet lamps 56 are electrically installed on opposite sides of the two sets of conductive rings 55. The conductive rings 55 are electrically connected to the power control board 10 through the circuit, thereby realizing the effect of controlling the start and stop of the ultraviolet lamps 56. When the ultraviolet lamps 56 irradiate, the ultraviolet rays fill the cavity 54 and reflect into the interior of the paper water pipe 53, thereby achieving the sterilization effect.
[0026] Several sets of heat dissipation fins 57 are fixedly installed on the outer arc surface of the protective cover 51. The heat dissipation fins 57 are evenly distributed vertically on the outside of the protective cover 51. Through the setting of the heat dissipation fins 57, the protective cover 51 can be quickly cooled, avoiding the overheating and damage of the internal ultraviolet lamp 56 caused by the excessive temperature of the protective cover 51.
[0027] A control panel 12 is installed on one side of the heater 11. The control panel 12 is electrically connected to one end of the power control board 10 via a circuit. Through the settings of the control panel 12, the device can be manually switched on and off and the heating temperature can be adjusted. The power control board 10 can indirectly control the start and stop of the heater 11 while increasing the power supply.
[0028] A set of temperature sensors 9 is installed through the middle of both the cold water connection valve 3 and the hot water connection valve 8. Both sets of temperature sensors 9 and the water flow sensor 2 are electrically connected to one end of the power control board 10 through a circuit. The temperature sensors 9 detect the temperature of the water flow and feed the signal back to the power control board 10. The power control board 10 controls the heating power of the heater 11 through the control system, thereby adjusting the effect of water flow heating temperature. The water flow sensor 2 is used to monitor the flow rate and flow of the water body and indirectly feeds back to the heater 11, thereby adjusting the heating power of the heater 11.
[0029] In use, the heater 11 is fixedly installed in the designated position. The inlet pipe 13 is connected to the main water supply pipe through the cold water connection valve 3. Then, the outlet pipe 14 is connected to the sterilizer 5 through the first flange 4. The sterilizer 5 is connected to the hot water connection valve 8 through the second flange 6. The hot water connection valve 8 is connected to the main hot water pipe. The corresponding lines are connected to the power control board 10 in sequence to achieve the effect of the entire water heater installation. The main water supply pipe discharges water into the heater 11 through the inlet pipe 13 for heating. The heated water flows into the water pipe 53 inside the sterilizer 5 through the outlet pipe 14. The ultraviolet lamp 56 is turned on to irradiate the water pipe 53, thereby achieving the effect of sterilizing the water. The sterilized water flows into the main hot water pipe and is then transmitted to the designated location for use.
