Description

Technical Field

[0001] This utility model relates to the field of water heater technology, specifically a wood-fired water heater. Background Technology

[0002] Hot water supply has always been a pressing issue in many remote areas and outdoor activity scenarios. As people pursue greater convenience and outdoor activities become more frequent, the demand for hot water supply equipment is also increasing. Firewood, as a widely available and renewable energy resource, is readily available in many areas, especially in mountainous regions, rural areas, and wilderness environments. Therefore, in remote areas, firewood stoves can be used to heat water.

[0003] Based on the above, the inventors have discovered the following problems: some existing simple firewood heating devices often suffer from low thermal efficiency, slow heating speed, and poor safety, making it difficult to meet people's requirements for efficient, safe, and convenient hot water supply.

One end of the first air duct 2002 passes through the base plate 2001 and communicates with the filter frame 2005. A second air duct 2004 is inserted into the bottom side of the housing 1001. One end of the second air duct 2004 is connected to the output of the blower 2003. The inlet is connected to the outlet. By installing a filter frame 2005, and having a metal filter screen inside the sealed opening on its outer side, it is possible to prevent fragments generated during firewood combustion from entering the filter frame 2005. By installing a blower 2003, when it is working, it can accelerate the blowing of outside air into the filter frame 2005, thereby accelerating the combustion efficiency of the firewood inside the housing 1001. By connecting one end of the second air duct 2004 to the inlet of the blower 2003, it is convenient for the blower 2003 to draw in outside air, and it is also convenient to disassemble and assemble.

[0031] 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.

[0032] Please see Figure 1 - Figure 5A heat insulation layer 1013 is provided on one side of the water tank 1008. A temperature sensor 1011 is installed inside the water tank 1008 on one side of the heat insulation layer 1013. A touch panel 1005 is installed on the upper side of one side of the tank body 1001. The touch panel 1005 is electrically connected to the temperature sensor 1011, the blower 2003, and the pump 1002 via wires. Handles 1006 are fixedly installed on both sides of the upper end of the tank body 1001. A heat insulation sleeve is fitted on the handle 1006. 3. To prevent the water temperature inside the water tank 1008 from rising and causing scalding to the user, a temperature sensor 1011 is installed to monitor the internal temperature of the water tank 1008 in real time. A touch panel 1005 is installed to facilitate the processing and display of the signal transmitted by the temperature sensor 1011, and to facilitate the user to control the blower 2003 and pump 1002 to start and stop. A handle 1006 is installed, and a heat insulation sleeve is fitted on the handle 1006 to facilitate the user to move the tank 1001.

[0033] Specifically, the working principle of this type of wood-fired water heater is as follows: When in use, the user connects the inlet pipe 1004 to the external water pipe, then starts the pump 1002. When the pump 1002 is working, it injects water into the water tank 1008. One end of the spiral heat exchange tube 1009 has a first connecting pipe 1010 that connects to the water tank 1008, and the other end has a second connecting pipe 1012 that extends through the casing 1001 to the outside and has an outlet pipe 1003. After the water enters the water tank 1008, the user pours firewood into the casing 1001 and ignites it. Simultaneously, the user turns on the blower 2003. 003. Outside air is blown into the filter frame 2005 through the first air duct 2002 and the second air duct 2004. The air passes through the metal filter screen from the air outlet 2006 and enters the box 1001, promoting the combustion of firewood. The heat generated by the firewood combustion heats the water tank 1008 and the spiral heat exchange tube 1009, thereby heating the water inside. With the continuous delivery of the pump 1002, the water inside the water tank 1008 is forced into the spiral heat exchange tube 1009. The water passes through the spiral heat exchange tube 1009 and can be heated again. The heated water is discharged from the outlet pipe 1003 for people to use.
