Air conditioner indoor unit

Abstract

The invention relates to an air conditioner indoor unit. The air conditioner indoor unit comprises a machine shell, a heat exchange device and at least one airflow drive device set. The machine shellis provided with a least one air inlet allowing environment air to enter and at least one air outlet allowing an inner air flow to flow out, at least one air outlet is formed in the front side of themachine shell, the heat exchange device is arranged in the machine shell and is arranged to exchange heat with at least part of air flow entering the machine shell through the at least one air inlet,at least one airflow drive device set is controlled to promote at least part of air flow in the machine shell to flow towards at least one air outlet, and comprises at least one first axial flow draught fan and at least one first ionic wind generating device, and the at least one first axial flow draught fan and the at least one first ionic wind generating device are arranged at the air flow flowing path, from at least one air inlet to at least one air outlet, in the machine shell in a series connection manner. The air conditioner indoor unit is large in air speed and air amount, and small innoise.

Description

technical field [0001] The invention relates to air-conditioning technology, in particular to an air-conditioning indoor unit. Background technique [0002] At present, most of the traditional wall-mounted air conditioner indoor units adopt the airflow circulation mode of upper air intake and lower air outlet, and the devices used to drive the air circulation are mostly cross-flow fans. The airflow enters the interior of the cross-flow fan along the axial direction perpendicular to the cross-flow fan, and passes through the impeller of the cross-flow fan twice. Inside the impeller, the airflow is forced to bend, which makes the pressure loss of the airflow larger and the air volume lower , the noise is louder when the whole machine is running. [0003] In order to avoid a series of problems caused by using a cross-flow fan to drive air circulation, some air-conditioning indoor units in the prior art replace the cross-flow fan with a centrifugal fan or an axial-flow fan.

AI Technical Summary

Problems solved by technology

Although this kind of air-conditioning indoor unit can solve the above-mentioned problems of low air volume and large airflow pressure loss to a certain extent, the effect is not particularly obvious, and it cannot solve the problem of high noise at all.

Defects that users can experience intuitively, such as loud noise and low air volume, have seriously affected the overall performance of the indoor unit of the air conditioner, and greatly limited the scope of use of the indoor unit of the air conditioner.

[0004] In order to reduce noise, the air-conditioning indoor units involved in some of the currently disclosed patent documents simply replace the fan with an ion wind device. However, the ion wind speed generated by the ion wind device is extremely limited, and the replaced air-conditioning indoor unit The wind speed is greatly reduced, which can hardly meet the most basic needs of users

It is precisely because there are many defects and impracticalities in the existing technical solutions, so far, the technology of using ion wind to supply air has only stayed at the most basic theoretical level
