Abstract
The utility model relates to a central air conditioner air duct of which air outlets are provided with semicircular arched air guiding flow channels and one-way valves. The air duct is provided with an air duct body and the 1-5 air outlets. The air outlets are square, the side length of the air outlets is a, and the air outlets are formed in a bottom plate of the air duct, the section of the air duct body is rectangular, and the central air conditioner air duct is characterized in that the air guiding flow channels are formed inside the air outlets and tightly attached to the bottom of the air duct body. Each air guiding flow channel is divided into an air inlet, a flow channel body and an air outlet flow guiding section. The air inlets face toward an air source, and the section of the air inlets and the section of the flow channel bodies are identically in a semicircular arch, and the air outlet flow guiding sections are adopted for connecting the flow channel bodies and the air outlets in an arc-shaped smoothness mode. The distance between the sides, close to the air outlets, of the flow channel bodies and the side edges of the air outlets is 0.1 a-0.2 a. The length of the air inlets is 0.3 a-0.4 a. The ratio of the length of the flow channel bodies to the length of the air inlets is 2.5-3, and slit-shaped holes are formed in the air inlets. The air void of the air inlets is 10-15%, the one-way valves are installed in the air inlets, the opening direction of the valves faces toward the air outlets, and the one-way valves are opened and close through torsion springs.
Description
Technical field
The utility model relates to ventilating duct for air-conditioner.
Background technology
The design in air channel is the important component part during central air-conditioning is installed with installing, and the effect of Duct design and installation, has directly determined the operational effect of air-conditioning and the Expenditure Levels of the energy.Passage of central air conditioner of the prior art is adopted the material such as aluminium sheet, galvanized sheet more and is made and inner lining as thermal insulation material, and in position opening for air-out, but the design of traditional duct outlet is difficult to accomplish that air-out is even, often air output successively decreases from the distance of wind regime according to air outlet, but Chinese patent ZL201320532538 discloses a kind of air-conditioning duct, adopt the mode at the flow deflector of air outlet place design differing heights, but we find that this flow deflector causes larger resistance to the flow field in air channel, has caused the loss of the energy.China ZL201320111164.2 discloses a kind of current-sharing air channel, adopt reducing air channel and the shielding plate that can adjust air port area, but we find, reducing air channel is from processing or install all comparatively difficult, and shielding plate is not easy to control air output, and this larger noise of easy generation under air-out condition of catch.Therefore provide a kind of air outlet amount that automatic adjusting and wind regime distance is different and air channel that should not produce noise simple in structure of can realizing to become and in prior art, need the problem that solves.
Utility model content
In order to solve the problem of above-mentioned existence, the utility model provides the passage of central air conditioner of a kind of air outlet tool Semicircular arched wind-guiding runner and check valve, described air channel has air channel body and 1-5 air outlet, air outlet is square, its length of side is a, air outlet is driveed in air channel base plate, this body section of air channel is rectangle, it is characterized in that having in air outlet inside the wind-guiding runner of being close to air channel body base plate installation, wind-guiding runner is divided into air inlet, runner body and air-out diversion section, air inlet is towards wind regime direction, it is identical semicircular arch that air inlet is cross section with runner body, adopt air-out diversion section that runner body and air outlet are adopted to arc smooth connection, wherein runner body is 0.1a-0.2a near the distance of air outlet side and air outlet side, air inlet length is 0.3-0.4a, runner body and air inlet length ratio are for being 2.5-3, on air inlet, have slit-shaped apertures, the porosity of air inlet is 10-15%, check valve is installed in air inlet, valve is opened direction towards air outlet, employing torsion spring opens and closes.
The passage of central air conditioner that the utility model provides, at the additional one section of wind-guiding runner towards wind regime in air outlet surface, and wind-guiding runner has Semicircular arched air inlet, integrated environment near space air outlet and air channel can be separated, thereby make blast in air channel be tending towards homogeneous, thereby make the air outlet amount different apart from wind regime can be basically identical, be convenient to the layout in air channel, on the air inlet surface of wind-guiding runner, slit-shaped apertures is set simultaneously, in air-supply process, , can automatically control air output by slit-shaped apertures, and be incorporated into the check valve in air port, can also by adjustment control valve open and close torsion spring elastic force control air output, adopt this design, can make the wind-guiding runner all can be general except most of parts of valve torsion spring, and can control air output by changing valve torsion spring elastic force, make the layout of air outlet more flexible, can be adapted to the installation of various space environments.
Brief description of the drawings
Fig. 1 is the wind-guiding flow passage structure schematic diagram of the utility model passage of central air conditioner.
Detailed description of the invention
