Description

A heating furnace with uniform heat dissipation

technical field

The invention relates to the field of heating equipment, in particular to a heating furnace with uniform heat dissipation.

Background technique

At present, the stoves used for home heating are generally wood-burning stoves, coal stoves or electric stoves, among which electric stoves are mostly single heating stoves, while wood-burning stoves and coal stoves and other combustion stoves mostly have both cooking and heating functions. Considering the convenience of use, the combustion stove with both cooking and heating functions is more popular. However, the existing combustion furnaces use firewood or coal as fuel on the one hand, and the acquisition of fuel will cause damage to the environment, and firewood and coal are not clean energy, and the combustion of fuel produces a large amount of smoke when used, which is serious to environmental pollution and partially harmful When the gas is not effectively discharged, there are still hidden dangers to personal safety, which do not meet the increasingly stringent environmental protection requirements. On the other hand, in order to discharge the flue gas as soon as possible and reduce the deposition of soot inside the furnace body, the existing combustion furnaces mostly adopt a straight-through smoke exhaust channel from bottom to top. The rapid loss causes waste of energy, and the heat in the upper and lower parts of the furnace body is unbalanced, and the heating effect is poor.

Contents of the invention

The present invention intends to provide a heating furnace with uniform heat dissipation, so as to solve the problem of unbalanced heat in the upper and lower parts of the combustion furnace and poor heating effect in the prior art.

In order to achieve the above object, the present invention adopts the following technical scheme: a heating furnace with uniform heat dissipation, including a panel, a furnace barrel, a foot box and a burner head, the furnace barrel includes an inner barrel and an outer barrel, and the outer barrel is connected between the foot box and the stove head. Between the panels, the bottom of the inner barrel is connected to the foot box, the lower air duct is formed between the inner barrel and the outer barrel, the top of the lower air duct communicates with the inner space of the inner barrel, and the air inlet connected to the inner space of the inner barrel is provided on the foot box ; The outer wall of the outer barrel is evenly distributed with a plurality of vertical upper air ducts in the circumferential direction, the bottom of the panel is provided with an upper airtight box connected with the upper air ducts, the upper airtight box is provided with an air exhaust port, the foot box includes a lower airtight box, and the lower A plurality of lower air outlets and a plurality of upper air outlets are annularly distributed on the sealed box, the lower air outlets are connected with the lower air ducts, and the upper air outlets are communicated with the upper air ducts.

The principle and advantages of this scheme are: in actual application, the fuel burns in the inner barrel through the burner, and the air inlet provides air for the inner barrel to ensure smooth combustion. The air outlet enters the lower airtight box, then enters the upper air duct from the upper air outlet, then enters the upper airtight box from the upper air duct, and finally discharges from the air outlet. Such a structure allows the hot air to enter the lower airtight box downwards first, and the hot air is filled in the lower airtight box through the annularly distributed lower and upper air outlets, fully heating the foot box, and then enters the upper air duct , heat exchange with the lower air duct in the upper air duct and heat dissipation to the outside at the same time, the hot air after heat exchange in the upper air duct still maintains a certain temperature, and enters the upper sealed box after passing through the upper air duct, and the upper sealed box And the panel is heated and then discharged. The heat dissipation air duct formed in this way allows the heat energy generated by combustion to follow the airflow to flow fully in the furnace body, and makes full use of the heat energy generated by combustion, so that the heat energy is relatively evenly distributed in the upper, middle and lower parts of the furnace body. Uniform heating and heating, the heating effect obtained by using such a heating stove is significantly better than that of products in the prior art.

Preferably, as an improvement, the lower air outlets and the upper air outlets are alternately distributed in a ring.

The ribs block the airflow and reduce the impact on the surrounding environment when the combustion exhaust is discharged. When clean energy such as methanol-based fuel is used, it can not affect the breathing of surrounding heating people. This also forms the concealment of the air exhaust port, making the heating furnace more beautiful in appearance, and the usable area on the panel is larger.

Preferably, as an improvement, a furnace port is provided in the middle of the panel, the furnace port is located above the furnace head, and a cover ring is detachably connected to the furnace port. In this way, the cover ring can be taken off to cook through the fire at the burner, and the cover ring can effectively prevent the loss of heat energy from the furnace mouth, so that it can be used for cooking and heating, which is more convenient to use.

Preferably, as an improvement, the foot box also includes an outer bucket plate surrounding the outer side of the lower sealed box, the air inlet is opened on the outer bucket plate, the lower sealed box is in a ring shape, and the air inlet communicates with the inner barrel through the middle of the lower sealed box. In this way, the outer barrel board can be used as the bottom support of the heating furnace, and can reduce the heat loss of the lower part of the foot box, ensure the overall heating effect of the foot box, and form a unidirectional airflow from the lower part to the upper part of the whole furnace body. The passage is more conducive to improving the utilization rate of heat energy.

Preferably, as an improvement, the air inlets are evenly distributed circumferentially on the top of the outer barrel, and the edge of the foot box is provided with a lower rib located outside the air inlets. In this way, the air can be evenly aired from the circumference, avoiding foreign matter on the ground from blocking the air inlet, ensuring stable air intake, and the lower side cover conceals and protects the air inlet to prevent the air inlet from being blocked by clothes on the legs or other foreign objects close to the ground.

Gas fuel or liquid fuel can be connected through the fuel pipe, and the fuel tank storing gas fuel or liquid fuel can be placed in the space below the lower sealed box and the inner side of the outer barrel plate, so that it has better convenience. And it can be applied to the supply of clean energy such as methanol-based fuel.

Preferably, as an improvement, there is only one air exhaust port, the air exhaust port is connected to the top of the panel, and the air exhaust port is connected with a smoke pipe. In this way, when the gas discharged after burning the fuel used contains harmful components or the indoor air flow is poor, the exhaust gas can be discharged to the outside through the smoke pipe. Such a situation can also be adapted to the situation of burning coal or firewood on the stove head.
