Description

Technical Field

[0001] This utility model relates to the field of water heaters, specifically a water heater that is easy to clean. Background Technology

[0002] A water heater is a device that heats cold water to provide hot water for people through various methods. Electric water heaters use electric heating elements to convert electrical energy into heat energy, which heats the water in the inner tank. Storage-type electric water heaters should be filled with water before being plugged in to avoid dry burning. When using them, pay attention to adjusting the water temperature and do not set the temperature too high to avoid scalding. The inner tank of an electric water heater needs to be cleaned regularly, generally recommended every 1-2 years. When cleaning, you can use a professional water heater cleaning agent. First, drain the water from the tank, then pour the cleaning agent into the tank, soak it for a period of time, and then rinse it clean with water.

[0003] Therefore, water heaters need to be cleaned regularly, but the cleaning work is quite troublesome. Existing water heaters have a drain pipe on the shell that is connected to the inner tank, but this drain pipe is usually sealed with a cap. When draining and cleaning, the cap has to be removed, and then the magnesium rod for descaling has to be taken out. The magnesium rod is usually connected to the drain pipe by threads. Over time, the magnesium rod will accumulate a lot of scale, which is troublesome to disassemble. For this reason, we have proposed a water heater that is easy to clean. Utility Model Content

The locking protrusions 17 correspond to the locking holes 8 on the drain pipe 4 and the locking protrusions 17 are engaged between the locking holes 8. The side of sealing block 18 facing away from cover 5 is in contact with the handle of the snap-fit ​​seat 7. The locking protrusions 17 are used to engage with the locking holes 8, and the sealing block 18 is used to fit with the snap-fit ​​seat 7. The reinforced snap-fit ​​rod 13 is engaged between the snap-fit ​​grooves 11.

[0027] Structural Description: Water Heater Body 1: As the main structure of the water heater, a hot water pipe 2, a cold water pipe 3, and a drain pipe 4 are fixedly connected through the cylindrical surface to hold and heat the water source.

[0028] Hot water pipe 2 and cold water pipe 3 are used to connect the hot water outlet and cold water inlet of the water heater, respectively, to provide input and output channels for hot water.

[0029] Drain pipe 4: Connects to the inner tank of the water heater and is used to discharge sewage and impurities from the inner tank. One end of drain pipe 4 is snapped into a magnesium rod structure, and the other end is equipped with a cap structure.

[0030] Magnesium rod structure (including magnesium rod 6, snap-fit ​​seat 7, snap-fit ​​rod 13): Magnesium rod 6 is used to remove scale in the inner tank of water heater, snap-fit ​​seat 7 is used to support magnesium rod 6, and snap-fit ​​rod 13 is snapped into the slot 11 in the drain pipe 4 to facilitate the installation and disassembly of magnesium rod structure.

[0031] The sealing structure (including the cover 5, connecting strip 14, limiting block 16, locking protrusion 17, and sealing block 18) is as follows: The cover 5 is used to seal the drain pipe 4 to prevent water leakage. The connecting strip 14 is used to connect the cover 5 to the drain pipe 4. The limiting block 16 engages with the annular protrusion 15 of the drain pipe 4 to ensure that the cover 5 will not fall off. The locking protrusion 17 engages with the locking hole 8 of the drain pipe 4 to enhance the sealing performance of the drain pipe.

[0034] Working principle: When it is necessary to clean the inside of the water heater body 1, disconnect the power supply and close the valves of the corresponding water pipes connected to the hot water pipe 2 and cold water pipe 3. The user removes the lower cover 5, and the locking protrusion 17 on the sealing block 18 deforms under force and moves out of the locking hole 8 along with the cover 5. When the cover 5 and the sealing block 18 move out of the drain pipe 4, the connecting strip 14 and the limiting block 16 move in the connecting hole 12. Rotate the cover 5 to move the drain pipe 4 outlet. Pull out the handle on the snap-fit ​​seat 7 to move the snap-fit ​​rod 13 out of the snap-fit ​​groove 11 between the annular snap-fit ​​grooves 10. Rotate the handle on the snap-fit ​​seat 7 to snap the connection. The rod 13 rotates between the annular slots 10. When the rod 13 rotates to the position of the corresponding slide groove 9, the rod 13 is moved out of the slide groove 9 by pulling out the handle on the locking seat 7. Finally, the locking seat 7 and magnesium rod 6 are removed, the sewage in the water heater body 1 is drained, and cleaning agent is sprayed into the water heater body 1. After cleaning, the valve corresponding to the cold water pipe 3 is opened to flush the cleaning agent in the water heater body 1. After cleaning, the valve corresponding to the cold water pipe 3 is disconnected, the magnesium rod 6 is replaced, and the drain outlet structure is assembled according to the above operation. After opening the water pipe valves corresponding to the hot water pipe 2 and the cold water pipe 3, the power is plugged in for use.
