AI Technical Summary

Technical Problem

The inner air guide plate of the existing air conditioner indoor unit is located in the air duct, and can only air out from between the small surface of the inner air guide plate and the lower wall of the air duct, resulting in a temperature difference between the upper and lower surfaces of the inner air guide plate when the air conditioner is in refrigeration mode, which is easy to produce condensation and even water drops fall, affecting the user's experience.

Method used

An air-conditioning indoor unit is designed, including a shell, a lower air guide plate and an inner air guide plate. The lower air guide plate is composed of the main air guide plate and the secondary air guide plate that are pivotally connected to each other. The inner air guide plate is pivotally connected to the air duct, which can divide the air duct into an upper air duct and a lower air duct, reducing the temperature difference on the surface of the inner air guide plate.

Benefits of technology

By approaching the temperature between the upper and lower surfaces of the inner air guide plate, the formation of condensation is avoided, the user experience is improved, and the user needs are adapted to user needs through different air supply modes, improving the comfort and practicality of the air conditioner.

Abstract

The air conditioner indoor unit comprises a shell, a lower air guide plate and an inner air guide plate, the shell is provided with an air duct, and one end of the air duct is provided with an air outlet; the lower air guide plate is used for opening or closing the air outlet; the lower air guide plate comprises a main air guide plate and an auxiliary air guide plate which are pivoted with each other, and the main air guide plate is rotationally connected with the shell; the inner air guide plate is pivoted in the air duct and located above the lower air guide plate, the front end of the inner air guide plate can move to the front side of the air outlet, and the inner air guide plate can divide the air duct into an upper air duct and a lower air duct. According to the air conditioner indoor unit, by changing the unfolding or folding angle of the main air guide plate and the auxiliary air guide plate, different air supply modes can be achieved, and different requirements of users are met; the inner air deflector can divide the air duct into the upper air duct and the lower air duct, so that the temperature between the upper surface and the lower surface of the inner air deflector is close, the inner air deflector is prevented from generating condensation when the air conditioner is in a refrigeration mode, and the user experience is improved.
