Air conditioner with air freshening function

Abstract

The invention relates to an air-conditioner with an air refreshing function. The air-conditioner comprises a base disc, a top cover, a back plate, a left lateral plate, a right lateral plate, an air outlet frame, an upper panel body and a lower panel body which form a machine casing together, a heat exchanger, a volute, a motor and the like which are arranged in the machine casing, air inlets arranged on the left lateral plate and the right lateral plate and a filtering screen assembly or a baffle rotatably installed at the position of the air inlets through a rotating shaft. The filtering screen assembly or the baffle is controlled by the motor to rotate with the rotating shaft as the center to open / close the air inlets. When smoke and dust are required to be removed, the motor controls the filtering screen assembly or the baffle to approach the air inlets, air needs to pass through a filtering screen to enter a volute air channel system to clear smoke and dust in the air. When smoke and dust removing is not required, the motor controls the filtering screen assembly or the baffle to be far away from the air inlets, and the air can directly enter the volute air channel system from the air inlets without affecting air inlet quantity of the air-conditioner. Therefore, working efficiency of the air-conditioner is improved.

Description

technical field [0001] The invention relates to an air conditioner, in particular to an air conditioner with the function of fresh air. Background technique [0002] An air conditioner can provide users with a comfortable indoor environment, and generally includes a compressor, a condenser, a throttling device, and an evaporator. It uses the refrigerating cycle of the refrigerant to provide heating, cooling or purifying air to the room. Air conditioners can be roughly divided into separate types and integrated types. [0003] Existing air conditioners prevent dust from entering the interior of the unit along with the air suction process when the indoor unit of the air conditioner is running, resulting in poor air quality. Usually, a filter screen for filtering dust is provided at the air inlet of the indoor unit. But when the user smokes indoors or there is a lot of smoke, the common filter screen cannot act on the smoke and dust, which makes the environmental quality worse...

AI Technical Summary

Problems solved by technology

However, in the air conditioner with the above structure, no matter whether there is a lot of smoke or dust in the environment, the air must pass through the filter before entering the air inlet, which cannot be flexibly changed according to the indoor conditions. When the air freshening function is not needed, the working efficiency of the evaporator is reduced. , and even affect the air intake of the air conditioner
