Description

A direct-injection fire cover and gas furnace

technical field

The utility model belongs to the field of stoves, in particular to a direct-injection fire cover and a gas stove.

Background technique

The flame cover body, also known as the fire distributor, is a device used by the burner to control the combustion conditions such as the size, direction, and shape of the gas injection. The shape of the flame is affected by factors such as the size and position distribution of the jet holes or grooves on the flame cover body. The main body of the fire cover on the market is the outer fire cover body with a single straight fire spray and the inner center straight fire spray, the outer fire cover body with double ring swirling fire spray and the inner center straight or horizontal fire spray, the outer fire cover body Single ring swirling fire spray fire plus straight fire spray fire and so on. These fire spraying methods are mainly two-layer fire spraying, that is, the center fire spraying and the outer layer fire spraying. The fire spraying is not uniform enough, which affects the heating, and the combustion is not sufficient, so the energy consumption is high, and the incompletely burned carbon monoxide in the gas will cause Environmental issues.

Utility model content

The embodiment of the utility model provides a direct-injection fire cover, which aims to solve the problems of insufficient gas combustion, high energy consumption, and insufficient heating efficiency of the existing fire-spray cover body.

The utility model embodiment is realized in this way, a kind of direct-injection fire lid, comprises:

Fire cover body;

central fumarole;

the inner fumarole, and

Outer jet holes;

The fire cover body is a ring, the central jet hole is arranged at the center of the fire cover body, the inner side jet hole is evenly arranged on the inner side of the fire cover body along the circumferential direction, and the outer side jet hole is arranged along the circumference of the fire cover body. Evenly arranged on the outer surface of the fire cover body.

Further, the circumference of the outermost layer of the fire cap body forms an inclined ring surface, and the outer gas injection holes are evenly distributed, and the shape is a regular hexagon.

Further, the inner side of the fire cover body is vertical, and the inner gas injection holes are evenly distributed, and the shape is a regular hexagon.

Further, the direct injection fire cover also includes:

The gas cavity is located between the inner gas injection hole and the outer gas injection hole, and its upper end surface is horizontal, and is divided into two sections.

Further, there is a cavity between the central jet hole and the inner jet hole.

Further, the direct injection fire cover also includes:

Round base to fit with gas stove.

The embodiment of the utility model also provides a gas stove, including the above-mentioned direct-injection fire cover.

In the embodiment of the utility model, the fire cover has three layers of gas injection, and air enters between each layer, so that the heating is more uniform and the utilization rate of heat energy is improved; the gas injection holes are uniform and fine, so that the combustion of gas is more complete and the emission of carbon monoxide is reduced , thereby reducing energy consumption.

Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

The direct-injection fire cover provided by the embodiment of the utility model includes a fire cover body 5, a central jet hole 1, an inner jet hole 3 and an outer jet hole 4, as shown in Fig. 1 and Fig. 3 .

The fire cover body 5 is a ring as a whole, the central jet hole 1 is arranged at the center of the fire cover body 5, the inner side jet hole 3 is uniformly arranged on the inner surface of the fire cover body 5 along the circumferential direction, and the outer jet hole 4 is evenly arranged on the inner side of the fire cover body 5 along the circumferential direction. On the 5 outer sides of the fire cover body.

In the embodiment of the utility model, the fire cover adopts three layers of gas injection holes, and a large number of columnar flames can form three layers of uniform and continuous stepped flames during combustion.

In the embodiment of the present invention, as shown in Figure 3, the outermost circumference of the fire cover body 5 forms an inclined torus, and the outer jet holes 4 are evenly distributed, a total of 90, with an interval of 4°, and the shape is a regular hexagon.

In this utility model embodiment, the side of the inner layer of the fire cover body 5 is vertical, and the inner jet holes 3 are evenly distributed, a total of 48, the interval is 7.5°, and the shape is a regular hexagon.

In the embodiment of the utility model, the gas chamber 51 is located between the gas injection holes on both sides. After the gas is full, it is sprayed from the inner gas injection hole 3 and the outer gas injection hole 4 under pressure. The upper end surface of the gas chamber 51 is horizontal and divided into two sections.

In the embodiment of the utility model, there is a cavity 2 between the central jet hole 1 and the inner jet hole 3 , and air can enter from the bottom of the cavity to mix with the gas ejected from the central jet hole 1 and the inner jet hole 3 .

In the embodiment of the utility model, the circular base 52 cooperates with the gas stove, and the gas enters the gas chamber 51 through it, and is ejected from the inner gas injection hole 3 and the outer gas injection hole 4 to form a flame.

The direct-injection fire cover in the embodiment of the utility model can be used in various gas furnaces.

The fire cover in the embodiment of the utility model has three layers of air injection, and air enters between each layer, which makes the heating more uniform and improves the utilization rate of heat energy; the air injection holes are uniform and fine, which makes the gas burn more fully and reduces the emission of carbon monoxide. Thereby reducing energy consumption.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
