Air intake structure, fresh air device and air conditioner

Abstract

The invention belongs to the technical field of air conditioning, and particularly relates to an air intake structure, a fresh air device and an air conditioner. The invention aims to solve the problem of affecting the fresh air function when the air valve of the fresh air system is applied to the fresh air air conditioner integrated machine. The air inlet structure of the present invention includes a cover and a valve plate assembly, a partition plate is arranged in the cover to divide the inner cavity of the cover into a first chamber and a second chamber, and a side wall of the cover is provided with a first air inlet and a second air inlet; the valve plate assembly includes a valve plate that can move between a first position and a second position, and in the first position, the first valve plate portion is located at the opening of the first chamber, The second valve plate portion leaves the opening of the second chamber; in the second position, the first valve plate portion leaves the opening of the first chamber, and the second valve plate portion is located at the opening of the second chamber. The air intake structure can use the indoor air to adjust the temperature of the fresh air to ensure that the temperature of the fresh air blown into the room is not too low. Since the opening of the second chamber is not fully opened, the air volume of the indoor air is effectively suppressed.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an air intake structure, a fresh air device and an air conditioner. Background technique [0002] The fresh air system is an effective air purification device that can bring fresh air from the outside into the room to optimize the indoor environment. The fresh air system is mostly used in public places such as hospitals and subways. It has a very complex air duct switching device, so that the fresh air system can switch between the fresh air mode, the mixed air mode, and the indoor air circulation mode, and the cost is high. [0003] The all-in-one fresh air and air conditioner is a device that integrates the air conditioner and the fresh air device, which can meet the integration and miniaturization requirements of households. However, the fresh air device in the all-in-one fresh air air conditioner only has a simple function of entering fresh air. When use...

Problems solved by technology

[0005] In order to solve the above-mentioned problems in the prior art, that is, to solve the problem of affecting the fresh air function when the air duct switching device of the fresh air system is applied to the integrated fresh air air conditioner, on the one hand, the present invention provides an air inlet structure. The wind structure includes a casing with an opening on one side and a valve plate assembly installed on the casing. The opening constitutes the air outlet of the air inlet structure. A partition plate is arranged inside the casing. The partition plate extends from the side of the casing opposite to the opening to the direction of the opening, so as to divide the inner cavity of the casing into a first chamber and a second chamber, and the casing A first air inlet corresponding to the first chamber and a second air inlet corresponding to the second chamber are provided on the side wall; the valve plate assembly can be positioned between the first position and the second position A valve plate that moves between, the valve plate includes a first valve plate part and a second valve plate part, the first valve plate part is a whole plate and its shape is adapted to the opening of the first chamber, the Ventilation openings are provided on the second valve plate portion and the shape of the second valve plate portion is adapted to the opening of the second chamber; the valve plate is configured such that, in the first position, the first A valve plate portion covers the opening of the first chamber, and the second valve plate portion opens the opening of the second chamber; in the second position, the first valve plate portion closes the opening of the second chamber. The opening of the first chamber is opened, and the second valve plate part covers the opening of the second chamber
