[0024] The cross-flow fan 6 is also called a cross-flow fan, which is an air handling device that adopts a direct drive mode. Air is sucked in from the air inlet of the fan, passes along the axis direction of the fan, and is discharged from the air outlet of the fan.

[0025] Compared with other traditional fans, crossflow fans have the following advantages:

[0026] First, it is energy-saving. The fan impeller and transmission of the crossflow fan are installed on the same axis, which makes the transmission more precise and can effectively save energy. Second, it is small in size and light in weight. The crossflow fan adopts direct drive and does not require a transmission belt or belt drive, making the fan structure more compact, the overall size smaller and the weight lighter. Third, it has low noise. The operating noise of the crossflow fan will be smaller than that of other fans. Using it in noise-sensitive occasions can effectively reduce noise pollution. Fourth, it is easy to maintain. The overall structure of the crossflow fan is simpler and has relatively fewer components, so maintenance is more convenient and quicker.

[0027] A lower partition 8 is provided below the upper partition 2. The lower partition 8 and the upper partition 2 are divided into a plurality of air cavities by a vertical plate 9. The top of one of the air cavities is connected to a primary air inlet 21. The upper partition 2 is provided with a plurality of secondary air inlets 22.

[0031] An oven 13 is provided on the side of the oven box 1 .

[0032] The specific working process of this utility model:

[0033] When in use, lighted firewood is placed in the fireplace and the air inlet grille 23 is controlled so that oxygen enters through the primary air inlet 21 and the secondary air inlet 22 respectively, so that the firewood and smoke are fully burned. The secondary air volume is controlled by the air inlet grille 23, so that the internal smoke burns more fully and the combustion efficiency of the fireplace is higher.

[0034] When the firewood burns normally, start the cross-flow fan 6, which introduces external cold air. When the cold air passes through the guide plate 12, it is fully heat exchanged by the inner back plate 4. The setting of the guide plate 12 increases the heat exchange time. Then the cold air passes through the inner top plate 5 for further heat exchange. After sufficient heat exchange, the hot air passes through the air outlet 102 and is discharged from the air outlet grille 7. The heat exchange efficiency of the fireplace is higher.

[0035] A through hole 104 is provided at the rear side of the furnace box 1. If the air humidification operation is not required, the through hole 104 is sealed by a sealing cover.

[0036] If the air is too dry due to high ambient temperature and low humidity, making it uncomfortable for people to live in, the air needs to be humidified. A certain amount of atomized water is injected into the through hole 104, which is heated along with the cold air and finally discharged from the air outlet grille 7. This increases the indoor humidity while further improving the heat exchange efficiency of the fireplace, making the living environment more comfortable and the fireplace more applicable.

[0037] Technical features not described in the present invention can be achieved through or by adopting existing technologies, and will not be elaborated here. Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
