Abstract
It the utility model is related to a kind of speed bump of central hollow air outlet, including chimney fan, the chimney fan is connected with air supply duct, the chimney fan is connected with the air supply duct by the air outlet at center, the side of the air outlet is the condenser pipe in the chimney fan, the opposite side of the air outlet is the exhaust hood in the air supply duct, the surface of the exhaust hood, which is equipped with, is covered with relieve heat hole, the exhaust hood covers the air outlet, the cold air that air outlet comes out can be distributed to air supply duct by the speed bump of the central hollow air outlet by exhaust hood, slow down wind speed can make the air-flow in air supply duct uniform again, so that the cold air of the air-supply window at rear has identical wind speed and temperature.
Description
Technical field
The technical field of central air-conditioning is the utility model is related to, more particularly to a kind of speed bump of central hollow air outlet.
Background technology
The application of central air-conditioning is more and more common, and the wind-force of central air-conditioning is powerful, good refrigeration effect, but central air-conditioning
Wind speed is too big, and the cold air of central air-conditioning is directly entered larger-size air supply duct from the less air outlet of size, and increases
The wind speed of cold air is added, and the air-flow in air supply duct is uneven, and the wind of each air-supply window can be caused when blowing indoors
Speed is different with temperature, causes refrigeration effect to have deviation.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of speed bump of central hollow air outlet.
The technical solution of the utility model is：A kind of speed bump of central hollow air outlet, including chimney fan, the outlet air
Cylinder is connected with air supply duct, and the chimney fan is connected with the air supply duct by the air outlet at center, and the one of the air outlet
Side is the condenser pipe in the chimney fan, and the opposite side of the air outlet is the exhaust hood in the air supply duct,
The surface of the exhaust hood, which is equipped with, is covered with relieve heat hole, and the exhaust hood covers the air outlet.
Preferably, the exhaust hood is the hemispherical dome structure with fixed edge edge, the relieve heat hole and the exhaust hood
Spherical surface is vertical.
Preferably, filter cotton is pasted with the outside of the exhaust hood, the filter cotton is identical with the shape of the exhaust hood.
The beneficial effects of the utility model are：
The speed bump of the central hollow air outlet of the utility model, can pass through exhaust hood by the cold air that air outlet comes out
Air supply duct is distributed to, slow down wind speed can make the air-flow in air supply duct uniform again so that the cold sky of the air-supply window at rear
Gas has identical wind speed and temperature；Filter cotton can also filter out the impurity of cold air at the same time.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model；
In figure：1. chimney fan, 11. air outlets, 2. air supply ducts, 3. exhaust hoods, 4. filter cottons.
Embodiment
Specific embodiment of the present utility model is referring to Fig. 1：
The utility model mainly discloses a kind of speed bump of central hollow air outlet, the wherein refrigeration of central air-conditioning and air-supply
Principle has been well known to those skilled in the art, therefore is no longer described in detail, while the schema hereinafter to be compareed, main to express and this
The related structural representation of utility model feature, also need not completely not draw according to actual size, first explanation.
A kind of speed bump of central hollow air outlet, such as Fig. 1, including chimney fan 1, the chimney fan 1 are connected with ajutage
Road 2, the chimney fan 1 are connected with the air supply duct 2 by the air outlet 11 at center, the side of the air outlet 11 be positioned at
Condenser pipe in the chimney fan 1, the opposite side of the air outlet 11 is the exhaust hood 3 in the air supply duct 2, described
The surface of exhaust hood 3, which is equipped with, is covered with relieve heat hole, and the exhaust hood 3 covers the air outlet 11, and the exhaust hood 3 is with fixation
The hemispherical dome structure at edge, the relieve heat hole is vertical with the spherical surface of the exhaust hood 3, and the outside of the exhaust hood 3 attaches
There is filter cotton 4, the filter cotton 4 is identical with the shape of the exhaust hood 3.
The cold air that air outlet 11 comes out can be distributed to air supply duct 2 by exhaust hood 3 by exhaust hood 3, slow down wind
Speed, the overall dimensions of exhaust hood 3 are suitable with the internal diameter of air supply duct 2, while relieve heat hole is vertical with the spherical surface of exhaust hood 3 makes
Air-flow in air supply duct 2 is uniform so that the cold air of the air-supply window at rear has identical wind speed and temperature；Filter at the same time
Cotton 4 can also filter out the impurity of cold air.
During work, come out, be blocked after running into exhaust hood 3, wind speed is put from air outlet 11 in the cold air that chimney fan 1 is formed
Slow, cold air is out uniformly distributed in air supply duct 2 from relieve heat hole, promotes have uniform cold air in air supply duct 2
Air-flow.
