Air inlet structure, fresh air device and air conditioner

Abstract

The invention belongs to the technical field of air conditioning, and particularly relates to an air inlet structure, a fresh air device and an air conditioner. The air inlet structure, the fresh air device and the air conditioner aim at solving the problem that the fresh air function is affected when an air valve of a fresh air system is applied to a fresh air and air conditioner all-in-one machine. The air inlet structure comprises a housing and a valve plate component, a partition plate is arranged in the housing to divide an inner cavity of the housing into a first cavity and a second cavity, and a first air inlet and a second air inlet are formed in the side wall of the housing; the valve plate component comprises a valve plate capable of moving between a first position and a second position; in the first position, a first valve plate part is located at the opening of the first cavity, and a second valve plate part leaves away from the opening of the second cavity; and in the second position, the first valve plate part leaves away from the opening of the first cavity, and the second valve plate part is positioned at the opening of the second cavity. The air inlet structure can adjust the temperature of fresh air through indoor air, so that it is guaranteed that the temperature of the fresh air blown into a room is not too low; and due to the fact that the opening of the second cavity is not completely opened, the air volume of the indoor air is effectively restrained.

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 introduce fresh outdoor air 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 complicated 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 internal circulation mode, and the cost is relatively high. [0003] The all-in-one fresh air conditioner is a device that integrates an air conditioner and a fresh air device, which can meet the integration and miniaturization requirements of household use. However, the fresh air device in the all-in-one fresh air conditioner only has a simple fresh air intake function. When i...

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 sid...
