Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to an air conditioner indoor unit and an air conditioner with the air conditioner indoor unit. Background Art

[0002] As the air conditioner is used for a longer time, the filter at the air inlet of the air conditioner indoor unit will inevitably become dirty and clogged due to the accumulation of dust. Once the filter is dirty and clogged, it will not only reduce the air intake of the air conditioner indoor unit and affect the performance of the air conditioner, but also cause secondary pollution of the indoor air quality.

[0003] In order to automatically clean the filter, an existing solution is to use a brush or a vibrator to clean the filter. However, the dust on the filter cleaned by the brush or the dust shaken off by the vibrator will float in the dust box. The dust floating in the dust box can easily re-attach to the filter, thereby affecting the cleaning effect of the filter.

[0004] In order to ensure that the air conditioner can operate normally during the filter cleaning process and to prevent the dust in the dust box from floating, another existing solution is to fill the dust box with water to adhere the dust to the water, and use a closed-loop filter to be set on the outside of the main drive shaft and the slave drive shaft so that the closed-loop filter can reciprocate around the main drive shaft and the slave drive shaft. However, since the filter is a closed-loop structure, there are two layers of filters in the normal direction of the filter, that is, the air inlet direction of the air conditioner indoor unit, which affects the air intake volume of the air conditioner indoor unit and causes the heat exchange performance of the air conditioner to decrease. Summary of the invention

[0005] In order to achieve the first purpose of the utility model, the utility model provides an air-conditioning indoor unit which can automatically clean the filter during heat exchange operation, has good filter cleaning effect, effectively increases the air intake and the air intake is adjustable, operates stably and reliably, and has a simple and compact structure.
