Description

Outdoor machine hood with automatic weather protection

technical field

The utility model relates to the technical field of gas water heater production, in particular to a smoke exhaust hood for an outdoor machine.

Background technique

Most of the exhaust outlets of existing outdoor gas water heaters are in front of the panel. When it rains heavily, rainwater can easily enter the water heater. To prevent rainwater from entering the machine, a smoke exhaust rain cover is a very common technology. Along with the acceleration of urbanization process in addition, the floors of residential buildings are getting higher and higher, and the higher the floors, the greater the wind, which is unfavorable for the smoke exhaust of high-rise users' gas water heaters. At present, although this common rain cover has a certain rainproof effect, due to the problem of wind direction, it cannot prevent rainwater from entering the chimney pipe, and cannot discharge rainwater in time, and when there is wind, it will seriously affect the smoke exhaust of the water heater, and then seriously affect the water heater. usage of.

Contents of the invention

The purpose of this utility model is to solve the deficiencies of the prior art and provide an outdoor machine smoke that is not only simple in structure, but also can effectively and smoothly discharge the high-temperature flue gas burned by the water heater, and can also prevent rainwater from entering the flue mouth. cover.

The utility model adopts the following technical solution to achieve the above object: an outdoor smoke hood for automatically sheltering from wind and rain, characterized in that it includes a fixed cylinder base with a partition, a rotating cylinder, a smoke exhaust pipe and a The rain cover, the rotating cylinder is movably set on the fixed cylinder base, and the side of the rotating cylinder is provided with multiple smoke exhaust holes; the smoke exhaust pipe is set in the middle of the fixed cylinder base, and the rainproof cover is set The top of the cylinder.

As a further illustration of the above scheme, the rainproof cover is provided with a semicircular rain shield, and the semicircular rain shield is located above the smoke exhaust pipe to shield the smoke exhaust pipe from wind and rain.

Further, the lower part of the rotating cylinder is movably sleeved on the base of the fixed cylinder, and there are positioning protrusions and annular grooves with concavo-convex fit between the rotating cylinder and the base of the fixed cylinder, so that the rotating cylinder can Rotate along the base surface of the fixed cylinder.

Further, the number of the positioning protrusions is 4, which are evenly arranged on the outer surface of the base of the fixed cylinder, and the annular groove is arranged on the inner wall of the rotating cylinder.

Further, the smoke exhaust pipe is vertically suspended in the middle of the partition, and the smoke inlet at the lower end of the smoke exhaust pipe is provided with a flange extending outward.

The beneficial effect that the utility model can reach by adopting above-mentioned technical solution is:

The utility model adopts a smoke exhaust structure mainly composed of a rainproof cover with a semicircular rain shield, a cylinder with a circular smoke exhaust hole, a smoke exhaust pipe, and a cylinder fixing seat with a partition. , mainly the upper part of the cylinder with a circular smoke exhaust hole, the force exerted on the sheltered part by the wind entering the airflow inside the cylinder, so that the mechanical automatic orientation rotates, and finally the smoke exhaust direction is consistent with the wind direction; Exhaust from around the smoke outlet, thus forming a negative pressure on the back, the greater the wind speed, the greater the negative pressure on the back, the more conducive to the exhaust of gas water heaters, it can be used with any outdoor gas water heater, and can solve the difficulty of exhausting smoke in high-rise buildings It can solve the problem of direct backflow of cold wind into the water heater in winter. It has simple structure, simple installation and low cost.

detailed description

The technical solution will be described in detail below in conjunction with specific embodiments.

As shown in Fig. 1-Fig. 4, the utility model is an outdoor machine smoke hood for automatically sheltering from wind and rain, which includes a fixed cylinder base 1 with a partition, a rotating cylinder 2, a smoke exhaust pipe 3 and a rainproof cover 4. The rotating cylinder is movably set on the base of the fixed cylinder, and the side of the rotating cylinder is provided with a plurality of smoke exhaust holes 5; The top of the cylinder. The rainproof cover 4 is provided with a semicircle rain shield, and the semicircle rain shield is positioned at the top of the smoke exhaust pipe to keep out the wind and rain for the smoke exhaust pipe. The smoke exhaust pipe 3 is vertically suspended in the middle of the partition, and the smoke inlet at the lower end of the smoke exhaust pipe is provided with an outwardly extending flange 3-1.

Further, the lower part of the rotating cylinder 2 is movably sleeved on the fixed cylinder base 1, and a concave-convex matching positioning protrusion 6 and an annular groove 7 are arranged between the rotating cylinder and the fixed cylinder base, so that The rotating cylinder can rotate along the base surface of the fixed cylinder. In this embodiment, the number of positioning protrusions is four, which are evenly arranged on the outer surface of the base of the fixed cylinder, and the annular groove is arranged on the inner wall of the rotating cylinder. Since the material of the positioning protrusion is stainless steel, it can be assembled through elastic deformation and annular groove. As shown in Figure 5, when the surrounding wind passes by, it will form a negative pressure in the leeward area, which is more conducive to smoke exhaust. When the wind is stronger, the smoke is easier to exhaust; when the winter wind is stronger, the cold wind will not enter the smoke pipe. Inside; it is more conducive to smoke exhaust and rain protection when there is heavy wind and rain.

Compared with the prior art, the utility model adopts a smoke exhaust structure mainly composed of a rainproof cover with a semicircular rain shield, a cylinder with a circular smoke exhaust hole, a smoke exhaust pipe, and a cylinder fixing seat with a partition , the automatic wind-shielding part in the device is mainly a cylinder with a circular smoke exhaust hole. The force exerted on the wind-shielding part by the airflow inside the cylinder through the wind enters the cylinder, so that the mechanical automatic guidance rotates, and finally the direction of smoke exhaust and the wind direction Consistent; the wind is discharged from around the smoke outlet, thereby forming a negative pressure on the back, the greater the wind speed, the greater the negative pressure on the back, the more conducive to the smoke exhaust of the gas water heater, it can be used with any outdoor gas water heater, and can solve the problem of high-rise The problem of difficult smoke exhaust and rainproof requirements can solve the problem of cold wind directly pouring into the water heater in winter, with simple structure, simple installation and low cost.

The above is only the preferred embodiment of the utility model, it should be pointed out that, for those of ordinary skill in the art, without departing from the inventive concept of the utility model, some deformations and improvements can also be made. Belong to the protection scope of the utility model.
