DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.

[0018] Embodiment 1

[0019] As Figures 1 to 2 shown, a stove with a hot air circulation device includes a base 1 and a furnace body 2 fixed on the base. A combustion chamber 3 and an oven 4 are arranged in the furnace body. In this embodiment, the above structures are all conventional structures of the prior art, so they are not described in detail.

[0020] In the actual application process, a hot air circulation pipe 5 is surrounded around the lower part of the outer wall of the furnace body and the base; in this embodiment, the hot air circulation pipe is a heat-conducting metal pipe body. Specifically, the hot air circulation pipe is an aluminum pipe body. The heat passing through the hot air circulation pipe can dissipate heat outward, so that a certain amount of heat also exists around the lower part of the furnace body, which is convenient for warming by a fire and heating.

[0021] During the actual application process, a discharge smoke pipe 6 is provided on the side of the furnace body, a smoke exhaust port 7 is provided on the upper part of the side wall of the furnace body, and a discharge channel 8 communicating with the discharge smoke pipe and a wind guide channel 9 communicating with the inlet of the hot air circulation pipe are provided on the smoke exhaust port; a damper switch 10 is provided in the discharge channel; the outlet of the hot air circulation pipe is communicated with the discharge smoke pipe through a discharge channel 11; the discharge channel, the wind guide channel and the discharge channel are located around the oven. In this embodiment, through the above structure, the hot smoke in the combustion chamber can directly discharge from the smoke exhaust port through the discharge channel, or the damper switch can be closed as needed, so that the hot smoke in the combustion chamber enters the hot air circulation pipe through the wind guide channel, and finally discharges into the discharge smoke pipe through the discharge channel. The hot air circulation pipe can dissipate heat outward, so that there is heat around the lower part and the base of the furnace body, which is convenient for roasting fire and heating operations. The inlet and outlet of the hot air circulation pipe are arranged staggeredly, so that the air flow can completely pass through the hot air circulation pipe for one circle.

[0022] During the actual application process, a cold air injection port 12 for reducing the temperature is fixed on the outer wall of the hot air circulation pipe. When the temperature of the hot air circulation pipe is too high as needed, cold air can be injected into the hot air circulation pipe through here, so as to achieve the purpose of reducing the temperature, and the practicability is strong.

[0023] Meanwhile, an anti-touching isolation net is arranged outside the hot air circulation pipe. The anti-touching isolation net can prevent the situation of scalding by the hot air circulation pipe and improve the use safety.

[0024] The utility model has positive effects: the structure of the utility model is reasonably arranged. The hot air circulation pipe is arranged at the lower part of the furnace body, so that the heat in the combustion chamber can be discharged from the discharge smoke pipe after passing through the hot air circulation pipe. Due to the heat conduction and heat dissipation of the hot air circulation pipe, a certain amount of heat can be achieved around the lower part of the furnace body, so that the effects of roasting fire and keeping out the cold can be realized, the heat of the stove is reasonably utilized, the heat utilization rate is improved, the use is stable and reliable, the applicability is strong and the practicability is good.

[0025] The standard parts used in this embodiment can be directly purchased from the market. For the non-standard structural components described in the instruction manual, they can also be directly processed according to the existing technical common sense without doubt. At the same time, the connection methods of each component adopt the mature conventional means in the existing technology, and the machines, parts and equipment all adopt the conventional models in the existing technology, so no specific description will be made here.

[0026] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And these obvious changes or modifications derived from the essential spirit of the present utility model still fall within the protection scope of the present utility model.
