Description

Technical Field

[0001] The utility model relates to the technical field of water heater equipment, and particularly relates to a water heater with efficient scale removal. Background Technique

[0002] The related technology provides a heat pump water heater, and its assembly method is as follows: first, install the water tank main body in the outer shell, then install the water receiving tray at the opening of the outer shell, and then foam between the water tank main body, the outer shell and the water receiving tray. After the foaming is completed, install components such as a heat pump module, a fan module, an electric control module and a decorative cover on the water receiving tray. This kind of heat pump water heater not only has low production efficiency, but also has poor maintainability.

[0003] The application number is CN202322370769.X, and a heat pump water heater is disclosed, including: a head assembly, one end of which has a water receiving tray; and a water tank assembly, one end of which has a transfer tray, and the water receiving tray and the transfer tray are fixedly connected. For this heat pump water heater, after the head assembly and the water tank assembly are respectively assembled, place the head assembly on the water tank assembly and align the water receiving tray with the transfer tray, and then fixedly connect the water receiving tray and the transfer tray. When any one of the head assembly and the water tank assembly is damaged, it can be directly disassembled and replaced. Therefore, this kind of heat pump water heater not only has high production efficiency, but also has good maintainability.

[0004] A heat pump water heater disclosed in the above document has the following defects: during the use of this water heater, water is heated and discharged by the heat pump, and impurities in the water will also be decomposed during the heating process. When these impurities accumulate in the machine, scale will be formed, and this machine cannot clean the scale remaining on the inner wall, reducing the water quality in this water heater.

[0005] It can be seen from this that the existing heat pump water heaters do not have the function of cleaning the scale on the inner wall, and it is necessary to improve the existing deficiencies to provide a function of cleaning the scale on the inner wall of the machine.

[0008] The utility model relates to a water heater with high-efficiency scale removal, which comprises a fixing structure and a heating structure. The heating structure is installed on the inner wall of the fixing structure. The fixing structure includes a shell cover. A direct current pipe and a plurality of heating pipes are arranged on the inner wall of the top of the shell cover. The lengths of the plurality of heating pipes are divided into three categories. The direct current pipe is located in the middle of the shell cover, and the heating pipes surround the periphery of the direct current pipe. A spiral blade is arranged in the middle of the direct current pipe. Fixing frames are installed on the outer walls of the bottoms of the direct current pipe and the inner ring heating pipes. The purpose of such a setting is that during the use of the water heater, water is discharged through a water tank. The water tank is connected to the shell cover, and the water tank transmits the water source downward into the direct current pipe. The outer shell provides overall dust protection for the heating structure. The power supply pipe is connected to a power source to enable the plurality of heating pipes to heat and operate. The heat of a large number of heating pipes heats the water source in the middle direct current pipe. The water flows downward in the direct current pipe to the top blade of the spiral blade and then flows downward rapidly through the spiral path of the spiral blade. Due to the inertia of water, when the water flows rapidly on the arc-shaped blade of the spiral blade, the water at the edge of the spiral blade splashes around the direct current pipe along the gap between the spiral blade and the direct current pipe. The impact force of the water flow cleans the scale on the inner wall of the direct current pipe. The scale slides downward along the inner wall of the direct current pipe and is stored on the second fixing frame. The heated water flow is discharged downward through a drain pipe. The bottoms of three different sizes of heating pipes are fixed by three fixing frames respectively, and the tops of the heating pipes are fixed by the shell cover. When a large amount of heat is generated in the heating pipes of different lengths, the water vapor flows downward through the inner walls of the heating pipes to the fixing frames at different heights. The water vapor is stably circulated downward through the holes in the three fixing frames. Finally, the water vapor flows to and accumulates on the inner wall of the bottom of the outer shell and is discharged through a drain pipe, improving the processing quality of the water by the water heater.

[0009] Furthermore, a second fixing frame is installed on the outer wall of the bottom of the middle ring of heating pipes. A drain pipe is arranged on the inner wall of the middle of the second fixing frame. The purpose of such a setting is that during the use of the water heater, the impact force of the water flow cleans the scale on the inner wall of the direct current pipe. The scale slides downward along the inner wall of the direct current pipe and is stored on the second fixing frame. The heated water flow is discharged downward through the drain pipe.

[0010] Furthermore, a third fixing frame is installed on the outer wall of the bottom of the outer ring heating pipes. The drain pipe penetrates through the two fixing frames and extends to the outside of the outer shell. The purpose of such a setting is that during the use of the water heater, when a large amount of heat is generated in the heating pipes of different lengths, the water vapor flows downward through the inner walls of the heating pipes to the fixing frames at different heights. The water vapor is stably circulated downward through the holes in the three fixing frames. Finally, the water vapor flows to and accumulates on the inner wall of the bottom of the outer shell.

[0011] Furthermore, a water tank is installed on the inner wall of the top of the shell cover, and the water tank penetrates the shell cover and is connected to the direct current pipe. The purpose of this setting is that during the use of this water heater, water is discharged through the water tank. The water tank is connected to the shell cover, and the water tank transmits the water source downward into the direct current pipe.

[0012] Furthermore, an outer shell is provided directly below the shell cover. Lock catches are provided at the four corners of the top of the outer shell. Mounting blocks are provided on the outer walls of the four sides of the shell cover, and the lock catches are snap-fitted into the inner walls of the mounting blocks. The purpose of this setting is that during the use of this water heater, the shell cover is fixedly installed on the top of the outer shell through the cooperation of the lock catches and the mounting blocks, which is convenient for disassembling the shell cover to clean the inner wall of the machine.

[0013] Furthermore, an energy supply pipe is provided on one outer wall of the outer shell, and a discharge pipe is provided at the bottom of the outer shell.

[0014] The utility model has the following beneficial effects:

[0015] (1) Through the settings of the spiral blade and the direct current pipe in the utility model, water flows downward in the direct current pipe to the top blade of the spiral blade and then rapidly flows downward through the spiral path of the spiral blade. Due to the inertia of water, when water flows rapidly on the arc-shaped blade of the spiral blade, the water at the edge of the spiral blade splashes around the direct current pipe along the gap between the spiral blade and the direct current pipe, and the impact force of the water flow cleans the scale on the inner wall of the direct current pipe.

The outer shell 101 provides overall dust protection for the heating structure 2. The power supply pipe 105 is connected to the power supply to make several heating pipes 203 heat and operate. The heat of a large number of heating pipes 203 heats the water source in the middle direct current pipe 202. The water flows downward in the direct current pipe 202 to the top blade of the spiral blade 205 and flows downward quickly through the spiral path of the spiral blade 205. Due to the inertia of water, when the water flows rapidly on the arc-shaped blade of the spiral blade 205, the water at the edge of the spiral blade 205 splashes around the spiral blade 205 and the gap with the direct current pipe 202 towards the periphery of the direct current pipe 202.

The bottom ends of the three different-sized heating pipes 203 are fixed by the three fixing frames 204 respectively, and the top ends of the heating pipes 203 are fixed by the shell cover 102. When a large amount of heat is generated in the heating pipes 203 with different lengths, the water vapor flows downward through the inner wall of the heating pipes 203 to the fixing frames 204 at different heights. The water vapor is stably circulated downward through the holes in the three fixing frames 204. The water vapor finally flows to the bottom inner wall of the outer shell 101 to accumulate and is discharged through the drain pipe 106, improving the processing quality of the water by this water heater.

[0026] A second fixing frame 204 is installed on the outer wall of the bottom ends of the middle ring of heating pipes 203.

The purpose of this setting is that during the use of this water heater, when a large amount of heat is generated in the heating pipes 203 of different lengths, water vapor flows downward through the inner wall of the heating pipes 203 to the fixing brackets 204 at different heights, and the water vapor is stably circulated downward through the holes in the three fixing brackets 204. Finally, the water vapor flows to accumulate on the inner wall at the bottom of the housing 101.

[0028] A water tank 201 is installed on the inner wall at the top of the shell cover 102, and the water tank 201 passes through the shell cover 102 and is connected to the DC pipe 202.

The water flows downward in the direct current pipe 202 to the top blade of the spiral blade 205 and then rapidly flows downward through the spiral path of the spiral blade 205. Due to the inertia of water, when the water flows rapidly on the arc-shaped blade of the spiral blade 205, the water at the edge of the spiral blade 205 splashes around the direct current pipe 202 along the gap between the spiral blade 205 and the direct current pipe 202. The impact force of the water flow cleans the scale on the inner wall of the direct current pipe 202.

The bottom ends of three different-sized heating pipes 203 are fixed by the three fixing frames 204 respectively, and the top ends of the heating pipes 203 are fixed by the shell cover 102. When a large amount of heat is generated in the heating pipes 203 of different lengths, the water vapor flows downward through the inner wall of the heating pipes 203 to the fixing frames 204 at different heights. The water vapor is stably circulated downward through the holes in the three fixing frames 204 and finally accumulates on the inner wall at the bottom of the outer shell 101. The water vapor is discharged through the exhaust pipe 106, improving the processing quality of the water by the water heater.
