Description

Technical Field

[0001] The utility model relates to the technical field of central air-conditioning air ducts, in particular to an air guide duct structure of a central air-conditioning. Background Art

[0002] The central air-conditioning system is an integrated air-conditioning solution suitable for large-space homes, office buildings, hospitals, hotels, airports, railway stations and other places. Because its air-conducting range is generally wide, it is often equipped with air ducts for the passage of hot and cold air.

[0003] The air duct of the central air conditioner is the channel used to transport processed air to each room or area in the air conditioning system. The air duct of the central air conditioner is an indispensable part of the air conditioning system. Its design, material selection and daily maintenance directly affect the performance of the air conditioning system and the indoor air quality.

[0004] The air duct of the central air conditioner is generally installed on the ceiling, fixed directly to the ceiling by expansion screws and pipe racks, and then covered by the ceiling panel.

[0005] Since the central air conditioner will generate hot or cold air and send it into the room through the air duct, the quality of air flow is often very important. If there is a lot of dust or bacteria in the duct, it will seriously affect the health of the people in the room. Therefore, the inside of the air duct needs to be cleaned frequently.

[0006] At present, pipe cleaning robots are often used for cleaning. However, the air duct of central air conditioners is generally long. Cleaning robots often cannot clean the entire air duct from the head, resulting in large cleaning omissions.

[0007] Temporarily dismantling the pipe from the middle for cleaning is inconvenient, increases the cleaning time, is inefficient, and brings inconvenience to the user. Utility Model Content

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] In the examples of this application, please refer to Figure 1 , 2 3. An air duct structure of a central air conditioner, comprising a duct 10, the outside of which is provided with a heat preservation cotton 20, the duct 10 refers to the currently commonly used air duct, the bottom of the duct 10 is provided with an inlet hole 30, the inside of the inlet hole 30 is rotatably provided with a guide plate 40 through a rotating shaft 41, the bottom of the duct 10 is movably provided with a protective sleeve 50 located below the inlet hole 30, the top of the protective sleeve 50 is fixed with a plurality of connecting plates 60, the connecting plates 60 are damped and slidably arranged on both sides of the duct 10 through a stabilizing structure 70, specifically, the protective sleeve 50 comprises a bottom plate 51 arranged below the duct 10, the area of ​​the bottom plate 51 is larger than the inlet hole 30, side plates 52 are fixed on both sides of the top of the bottom plate 51, the side plates 52 and the connecting plates 60 can be close to the sides of the duct 10, the side plates 52 and the connecting plates 60 are fixedly connected, and an extension plate 53 is fixed on the side of the bottom plate 51;

[0037] When it is necessary to clean the inside of the pipeline, the protective cover 50 is moved down to the lowest point of the stroke. At this time, the guide plate 40 will naturally move down at one end under the action of gravity, and the guide plate 40 will rotate as a whole to form an inclined surface. Then the user puts the pipeline cleaning robot on top of the extension plate 53, and then starts the pipeline cleaning robot used. It can pass through the bottom plate 51 and the guide plate 40 to enter the inside of the pipeline 10, and then use the existing method to clean the inside of the pipeline. After cleaning, move the protective cover 50 back. The operation is simple, and it is convenient for the user to clean the inside of the pipeline as a whole. It can solve the problem that the pipeline is too long and it is inconvenient to clean the whole pipeline, so as to ensure the cleaning quality and the cleaning efficiency is also higher.

[0038] For further examples, see Figure 1 and 3The stabilizing structure 70 includes a guide groove 71 opened inside the connecting plate 60, and a guide sleeve 72 slidably arranged inside the guide groove 71 is fixed on the side of the pipe 10, and one end of a tension spring 73 is fixed inside the guide sleeve 72, and a movable plate 74 is fixedly connected to the other end of the tension spring 73, and the movable plate 74 is fixedly connected to a friction pad 75 which is close to the connecting plate 60. The tension spring 73 is in a tensioned state. When in use, the tension given by the tension spring 73 will always act on the movable plate 74, thereby driving the friction pad 75 to always be close to the connecting plate 60, generating a large amount of friction, thereby limiting the sliding of the connecting plate 60, and finally limiting the sliding of the protective cover 50, so as to ensure the stability of the protective cover 50 in normal use. When adjustment is needed, the user can move the protective cover 50 by manually pulling or pushing, which will not affect the normal use function.

[0039] The above-mentioned air duct structure of the present application can be set at a suitable position, which depends on actual needs. When the pipeline is short and a pipeline cleaning robot can be used to perform complete cleaning at the end, the above-mentioned structure may not be set, which depends on actual conditions.
