DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] The embodiment of the present application discloses a high-efficiency water heater.

[0023] Reference Figure 1 and Figure 2 The high-efficiency water heater includes a furnace body 1. Four raising blocks 16 are fixedly connected to the bottom of the furnace body 1. The four raising blocks 16 are evenly distributed at the bottom of the furnace body 1. The raising blocks 16 facilitate the operator to carry the furnace body 1 as a whole. A heating device is provided in the furnace body 1. The heating device includes a bracket provided in the furnace body 1. The bracket is bolted to a support block 9. The end of the support frame facing away from the bracket is provided on the furnace body 1. The support frame supports the bracket, reduces the possibility of the bracket shaking, improves the stability of the bracket inside the furnace body 1, and improves the structural rigidity of the bracket. An air inlet pipe 2 and a heating pipe 3 are provided on the bracket. The air outlet end of the air inlet pipe 2 and the air inlet end of the heating pipe 3 are connected by a guide unit. The air outlet end of the heating pipe 3 is connected to the air outlet pipe 4. In the embodiment of the present application, a plurality of heating pipes 3 are provided, and the plurality of heating pipes 3 are arranged in an array along the outer edge of the air inlet pipe 2, so as to facilitate uniform heating of the water in the furnace body 1 and improve heating efficiency.

[0024] Therefore, the hot gas generated by the combustion of fuel enters the furnace body 1 through the air inlet pipe 2, and the hot gas is then transported from the air outlet end of the air inlet pipe 2 to the air inlet end of the heating tube 3. The guide unit provides guidance for the hot gas at the air outlet end of the air inlet pipe 2, so that the hot gas enters the heating tube 3 along the guide direction of the guide unit, reducing the concentration of heat energy at the air outlet end of the air inlet pipe 2 and the local excessive temperature. The heating tube 3 transfers the thermal energy of the hot gas to the water, increases the water temperature, and improves the efficiency of hot gas transportation and the heating efficiency of the water in the furnace.

[0025] Reference Figure 2 and Figure 3 The guide unit includes a disc-shaped conducting pipe 5 arranged on the bracket, and the outlet end of the air inlet pipe 2 and the air inlet end of the heating pipe 3 are both connected to the conducting pipe 5, wherein the outlet end of the air inlet pipe 2 is connected to the center of the disc-shaped conducting pipe 5, and a conical guide block 6 is fixedly connected to the inner wall of the conducting pipe 5. The conical guide block 6 is arranged at the outlet end of the air inlet pipe 2, and the hot air at the outlet end of the air inlet pipe 2 is transported to the inlet end of the heating pipe 3 after passing through the inclined surface of the conical guide block 6.

[0026] Therefore, in the related art, when a water heater that is not provided with a conical guide block 6 is in use, hot air is concentrated at the outlet end of the air inlet pipe 2, causing the local temperature there to be too high, and the transportation efficiency of the hot air from the outlet end of the air inlet pipe 2 to the inlet end of the heating tube 3 is poor. The embodiment of the present application provides a guiding effect on the transportation direction of the hot air through the inclined surface of the conical guide block 6, so that the hot air enters the heating tube 3 along the inclined surface of the conical guide block 6, thereby reducing the concentrated accumulation of heat energy at the outlet end of the air inlet pipe 2 and the local excessive temperature.

[0027] Reference Figure 1 and Figure 2 A disc-shaped transmission pipe 7 is mounted on the bracket. The outlet end of the heating pipe 3 is connected to the transmission pipe 7. The transmission pipe 7 and the conducting pipe 5 are located at both ends of the heating pipe 3. A guide pipe 8 is connected to the transmission pipe 7. The outlet pipe 4 is located at the end of the guide pipe 8 facing away from the transmission pipe 7 and is connected to the guide pipe 8. Therefore, the hot gas passes through the inlet pipe 2, the conducting pipe 5, the heating pipe 3, the transmission pipe 7, and the guide pipe 8 in sequence before being discharged from the furnace body 1 through the outlet pipe 4. The guide pipe 8 guides the output direction of the hot gas. The guide pipe 8 can be set with different bending shapes according to the actual situation on site to control the output angle and direction of the hot gas, which is more flexible.

[0028] Reference Figure 1 and Figure 4 The end of the outlet pipe 4 facing away from the furnace body 1 is connected to a reflux box 10. An exhaust pipe 11 is fixedly connected to the reflux box 10. A filter 14 is installed in the exhaust pipe 11. The hot gas discharged through the outlet pipe 4 is partially discharged through the exhaust pipe 11. The filter 14 filters impurities in the hot gas passing through the exhaust pipe 11. A fan is installed in the reflux box 10. The air inlet end of the fan is connected to the air supply pipe 12. The air outlet end of the fan is connected to a reflux pipe 13 that communicates with the air inlet end of the air inlet pipe 2. At the same time, the reflux pipe 13 is connected to the reflux box 10.

[0029] Therefore, the hot air is discharged into the return box 10 through the outlet pipe 4, the fan is started, and air is extracted through the air supply pipe 12. The return pipe 13 synchronously transports part of the hot air in the return box 10 and the extracted air to the air inlet end of the air inlet pipe 2, thereby capturing the waste heat emitted by the water heater. By recycling the waste heat, it can reduce dependence on new energy, reduce energy consumption, thereby improving the overall energy utilization efficiency, and indirectly reduce carbon emissions generated by energy production, which is conducive to reducing production costs.

[0030] Reference Figure 1 and Figure 4The end of the reflux box 10 facing the exhaust pipe 4 is fixedly connected to a first mounting ring 15, and the end of the exhaust pipe 4 facing away from the furnace body 1 is fixedly connected to a second mounting ring. The first mounting ring 15 and the second mounting ring are connected by a connecting unit. The connecting unit includes mounting bolts that pass through the first mounting ring 15 and the second mounting ring in sequence. The outer edge of the mounting bolt is threaded with a mounting nut that matches the mounting bolt size. The second mounting ring is tightened between the mounting bolt and the mounting nut. Therefore, the operator can remove the reflux box 10 from the second mounting ring by removing the bolts, achieving a detachable connection of the reflux box 10 and greater flexibility.

[0031] The implementation principle of the embodiment of the present application is as follows: the hot gas generated by the combustion of fuel enters the furnace body 1 through the air inlet pipe 2, and the hot gas is then transported from the air outlet end of the air inlet pipe 2 to the air inlet end of the heating tube 3. The inclined surface of the conical guide block 6 provides a guiding effect on the hot gas transport direction, so that the hot gas enters the heating tube 3 along the inclined surface of the conical guide block 6, thereby reducing the concentrated accumulation of heat energy at the air outlet end of the air inlet pipe 2 and the local excessive temperature. The heating tube 3 transfers the thermal energy of the hot gas to the water, thereby increasing the water temperature and improving the efficiency of hot gas transportation and the heating efficiency of the water in the furnace.
