Description
Technical Field
[0001] The utility model relates to the technical field of wood-fired stoves, in particular to a heat-cycle wood-fired stove. Background Art
[0002] A heat cycle wood stove is a device that uses firewood as fuel. It achieves efficient use of heat and reduced emissions through a specific design. The current wood stove heating method on the market is relatively simple, that is, using firewood to burn the furnace body to reach a certain temperature, thereby releasing heat and outputting heat to the unit space, thereby achieving the effect of heating and heating. The wood stove has a single heating function, and the heat generation and transmission speed is slow. In a low temperature environment, it is difficult to quickly solve the heating effect required by the human body. It is necessary to wait until the entire furnace body is fully burned and generates high temperature before heat diffusion. Now there is a need for an accelerated heating system integrated with the furnace body to solve this problem. The existing technology furnace function speed is not enough and the waiting time is long, so we invented a heat cycle auxiliary system for accelerated heating that is integrated with the furnace body. The innovation point is that the heating system is not a separate product, but is integrated with the furnace body in design, which does not take up space and greatly improves the heating rate of the wood stove.

[0031] Working principle: The wood stove generates original heat through combustion, and then the heating auxiliary system invented this time can quickly absorb external air into the inlet of the airflow pipe 11 after starting work, and then disperse the flow from the inlet to the designed internal airflow pipe 11. When the gas flows through the pipeline, the airflow passes through the inside of the furnace body 1 during the flow process, and the airflow is quickly heated by the burning furnace body 1. After this process, the heat cycle of the cold air is completed, so that the airflow ejected from the outlet becomes a hot circulating airflow. At this time, the heating rate of the entire furnace body 1 will be greatly improved, and the required heating time will also be shortened, which can more efficiently provide the supplementary heat required by the human body. Compared with the traditional single heating method, this invention design solves the long-standing pain point.
