Description

A stove type water heater

technical field

The utility model belongs to the technical field of heat supply and relates to a stove-type water heater which realizes heating and domestic hot water supply by using flue gas and stove waste heat.

Background technique

Stoves are the main living energy-consuming facilities in rural areas in northern my country. On the one hand, stoves are the main heat source for family cooking. In the structural system of rural energy consumption, almost 80% of the energy is consumed around stoves. During the process of burning fire and cooking, the heat generated by burning straw and firewood in the stove is divided into three parts, including the heat consumed by cooking, the heat taken away by the smoke, and the heat lost by the stove wall and stove door. Through on-the-spot research, it was found that the heat loss of the stove wall and the stove door is relatively large. At the same time, due to the high temperature of the flue gas, the temperature of the surface of the Kang head is relatively high, so the temperature of the entire Kang surface is relatively uneven. The comfort is poor during use. Based on these problems, it is very necessary to develop some kind of equipment to make full use of the heat energy generated by fuel combustion, the heat lost by the stove wall and stove door, reduce the temperature of flue gas, and then improve the total utilization rate of heat energy of fuel combustion.

Utility model content

The technical problem to be solved by the utility model is to provide a kind of heating and domestic hot water for households by using the heat lost by the wall of the stove and the waste heat of flue gas during cooking, and at the same time improve the total utilization rate of heat energy of fuel combustion.

The technical scheme of the utility model is as follows:

The stove-type water heater of the utility model is mainly composed of a lower connection pipe, an upper connection pipe, a heat exchange pipe, a running air, a stove grate, a stove top, a pot and a wall. The lower connecting pipe, the upper connecting pipe, the heat exchange tube and the running air constitute the heat exchange device of the present utility model. The upper pipe and the heat exchange pipe are arranged around the inner wall of the cooktop in a circular table shape. The water inlet pipe is connected to the lower pipe, and the outlet pipe is connected to the upper pipe. The wind is connected to the upper connecting pipe and is located at the end of the water outlet pipe, the lower connecting pipe is located below the stove grate, and the upper connecting pipe is located below the upper edge of the cooktop; the cooktop is connected to the wall, and the upper mouth of the pot is close to the inner wall of the cooktop.

The heat exchange tube of the stove-type water heater of the utility model can be a copper tube or a steel tube.

The effects and benefits of the utility model are: 1. Use the heat lost by the stove wall and the waste heat of flue gas to provide heating and domestic hot water while cooking; 2. Improve the heat energy utilization rate of fuel; The device has a simple structure, is easy to process, has low cost, and is easy to popularize and apply.

Detailed ways

The specific embodiment of the utility model is described in detail below in conjunction with technical scheme and accompanying drawing.

The stove-type water heater of the utility model is mainly made up of lower connection pipe 1, upper connection pipe 2, heat exchange pipe 3, running wind 4, stove grate 5, stove top 6, pot 7 and body of wall 8. The lower connecting pipe 1, the upper connecting pipe 2, the heat exchange pipe 3, and the running air 4 constitute the heat exchange device of the present utility model. The pipe 2 and the lower pipe 1 are welded, the lower pipe 1, the upper pipe 2 and the heat exchange pipe 3 are arranged around the inner wall of the cooktop 4 in a circular platform shape, the water inlet pipe is connected to the lower pipe 1, the water outlet pipe is connected to the upper pipe 2, and the inlet The water pipe and the outlet pipe are installed on the same side to form a same-course circulation pipeline. The running air 4 is connected to the upper connecting pipe 2 and is located at the end of the outlet pipe. The lower connecting pipe 1 is located below the stove grate, and the upper connecting pipe 2 is located below the upper edge of the stove 6. When working, the cold water enters the lower connecting pipe 1 through the water inlet of the stove-type water heater, and is heated in the heat exchange pipe 3, and the heated hot water flows out of the stove-type water heater through the upper connecting pipe 3 from the water outlet, and the running air 4 is used for exhaust The stove 6 is connected to the wall 8, and the top of the pot 7 is close to the inner wall of the stove; the heat exchange tube 3 can be a copper pipe or a steel pipe.
