Abstract

The utility model relates to a closed combustion smoke exhausting hood, which is composed of three parts such as an outer shell, an inner shell, and an exhaust opening, wherein, the outer shell and the inner shell are fixedly connected into a whole, and a winding air passage is formed at the center, and the exhaust opening is connected to the outer shell and is communicated with the winding air passage. The utility model can be used for a household coal oven, the coal gas can be effectively exhausted, the indoor environmental pollution can be prevented, the coal can be fully burned, and more heat energy can be obtained. The utility model has the advantages of easy installation and economy.

Description

Sealing burning and gas-exhausting cover

The utility model is to belong to a kind of domestic stove utensil.

At present, the honeycomb briquette kitchen range that family uses because of coal gas is heavy, is easy to pollute and damages household implements, and the harm people's is healthy, and gets rid of the utensil of coal gas when not having to make the honeycomb briquette burning.

The purpose of this utility model provides the enclosed burning hood that a kind of domestic stove is used.It can get rid of coal gas effectively, makes household implements no longer by corrosion, and the healthy of household no longer endangered.

The purpose of this utility model is achieved like this: this cover is that to change the traditional combustion system of honeycomb briquette kitchen range be the enclosed burning mode, it is made up of shell, inner casing and exhaust outlet three parts, shell connects with inner casing to be consolidated into whole, the centre becomes one around air flue, exhaust outlet is connected on the shell, and communicates around air flue.

The utility model is owing to having adopted above technical solution, so structure is simple especially.Cover on the domestic stove, can get rid of coal gas effectively, prevented indoor environmental pollution.This cover can make coal be fully burned and obtain more thermal energy, reduces the loss of heat energy, makes it to obtain to greatest extent to utilize.So cook, boil water quick combustion, fiery strength foot.After tested, 0.5 kilogram of rice only needs 15 minutes, and 5 pounds of boiling water only need 8 minutes.And use this cover to install very easily, economical.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is a section shape structural representation of the present utility model;

1---shell 2---inner casing 3---around air flue 4---exhaust outlet

Fig. 2 be Fig. 1 look up the shape and structure schematic diagram;

5---the hole

Fig. 3 is the plan view shape structural representation of Fig. 1;

Fig. 4 is that A-A looks the shape and structure schematic diagram among Fig. 1.

Below in conjunction with accompanying drawing the utility model is described in detail.

This cover comprises a shell [1], inner casing [2] and exhaust outlet [4], and shell [1] is connected in aggregates with inner casing [2], forms one in the middle of making around air flue [3], and exhaust outlet [4] is connected the bottom of shell [1], makes it and directly communicates around air flue [3].

As shown in Figure 4, the end face of inner casing [2] evenly distributes and processes porose [5].

During use, the exhaust outlet [4] of this cover is connected in the externally connected exhaust pipe of body of wall, coal gas sucks from hole [5] and enters around air flue [3], makes coal gas form loop and discharges from exhaust outlet [4], reaches and gets rid of the pollution of coal gas to indoor environment.

This cover can be processed into difformities (the utility model accompanying drawing is square) such as circle, with suitable different needs.
