Description

Central air conditioning air outlet baffle structure

Technical Field

The utility model relates to an air conditioner technical field, concretely relates to central air conditioning air outlet baffle structure.

Background

When the indoor unit of the central air conditioner works, an air outlet and an air return inlet are generally arranged in the indoor unit in a matched mode, so that a circulating air duct which flows back to the indoor unit is formed. Generally, a diffuser is installed at an air outlet of the central air conditioner to uniformly disperse the air outlet direction of the internal unit, so that hot air or cool air blown into the room is diffused into the room.

The air diffuser used at the air outlet of the central air conditioner is generally in a square or round multilayer structure and is detachably arranged at the air outlet. For example, a common square diffuser, also called a diffuser, includes multiple layers of blades from inside to outside, an innermost is a single square or round small-sized cover plate, then there are at least two layers of cover plate structures step by step outward, each layer of cover plate structure includes a ring-shaped structure formed by connecting at least three blade plates end to end, and each blade plate is a long metal or plastic sheet. Between the blade plates between adjacent layers is an air outlet opening in a certain direction. The length of the blade plate is gradually increased from inside to outside, so that the blade plate at the outermost layer is longest. When each layer of blade plate has four blades, the single-layer structure is an annular rectangular structure. However, the blade plates of the conventional air diffuser are generally fixed, so that the air outlet efficiency of the conventional air diffuser cannot be adjusted according to actual conditions no matter whether the conventional air diffuser blows cold air or hot air or strong or weak air. Moreover, a general central air conditioner can only see the set air outlet strength grade on the control panel, but cannot find the real-time air outlet state when the equipment runs, so that a user can adapt to the current wind power only by means of fuzzy feeling.

Therefore, the conventional structure has the following disadvantages in use:

1) generally, the opening degree of the air outlet cannot be adjusted, that is, the opening area of the air outlet is fixed, and the structure has the disadvantages that if the air outlet is of a fixed large opening structure, the wind force cannot be concentrated and the cooling or heating effect is slow in weak wind, and if the air outlet is of a fixed non-large opening structure, the wind force effect is limited by the opening degree of the opening in strong wind so that the strong wind effect is also 'discounted';

2) generally, the strength of wind power cannot be indicated, and even in weak wind, whether the current equipment is in an operating state cannot be checked, or when the strength of the current wind power output by the air conditioner is to be acquired, related information must be acquired at the control panel, and the wind power strength grade data displayed on the control panel is only a set value, but not the real-time state of the air outlet.
