Air conditioner with air refreshing function

Abstract

The invention relates to an air conditioner with air refreshing function, comprising: a chassis, a top cover, a back plate, a left side plate, a right side plate, an air exhaust frame, an upper plate body and a lower plate body which jointly form a casing; air conditioner components arranged inside the casing, such as a heat exchanger, a volute casing, an electric motor and the like; air inlets arranged on the left side plate and the right side plate; and filter screen modules or baffle plates which can be rotatably mounted at the air inlets via rotating shafts, wherein the filter screen modules or the baffle plates are controlled by the electric motor so that the rotating shafts implement central rotation to open / close the air inlets. When smoke and dust need to be removed, the electric motor control the filter screen modules or the baffle plates to get close to the air inlets, the air can enter a volute casing air channel system only after passing through the filter screen so that smoke and dust in the air can be cleared away; when smoke and dust do not need to be removed, the electric motor control the filter screen modules or the baffle plates to get away from the air inlets, the air can enter the volute casing air channel system directly from the air inlets without having an effect on the air intake of the air conditioner, thereby enhancing the working efficiency of the air conditioner.

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
