Air purifying assembly, air conditioner and control method of air conditioner

Abstract

The invention discloses an air purifying assembly which comprises a support plate, multiple filtering screens and drive elements, wherein the filtering screens are rotatably arranged on the support plate, and the driving elements are used for driving the filtering screens to turn. Each drive element at least comprises a first drive position and a second drive position. When the drive elements drive the filtering screens to be at the first drive positions, the filtering screens are sequentially arranged in an end-to-end mode, in butt joint or stacked, and the end faces of the filtering screens achieve filtering in the air inlet direction. When the drive elements drive the filtering screens to be at the second drive positions, the head portions and the tail portions of the filtering screens are sequentially separated, the end faces of the filtering screens form air inlet channels in pairs and allow air to pass. The invention further discloses an air conditioner and a control method thereof. The aim of purifying the air is achieved, and smooth circulation of the air is not influenced.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air cleaning assembly, an air conditioner and a control method thereof. Background technique [0002] In order to reduce the concentration of indoor particulate matter and improve the cleanliness of indoor air, at present, air conditioners often directly add fixed air purification components to the air return channel or air outlet channel to filter the particulate matter in the indoor air. see figure 1 as shown, figure 1 It is a structural schematic diagram of an air purification assembly in the prior art, which includes a support plate 10' and a purification filter 20', wherein the purification filter 20' is fixed on the support plate 10', so that the air purification assembly is installed on the air conditioner After the air return channel or the air outlet channel of the air conditioner, the air purification component will block the return air channel or the air outlet cha...

Problems solved by technology

see figure 1 as shown, figure 1 It is a structural schematic diagram of an air purification assembly in the prior art, which includes a support plate 10' and a purification filter 20', wherein the purification filter 20' is fixed on the support plate 10', so that the air purification assembly is installed on the air conditioner After the air return channel or the air outlet channel of the air conditioner, the air purification component will block the return air channel or the air outlet channel. When the air is supplied, due to the blocking of the purification filter, the air resistance is relatively large, making the temperature adjustment speed of the air conditioner slower. Slow, and, because the purification filter screen 20' of this air purification assembly configuration is a HEPA material filter screen, because the HEPA material is a fine pore material, and it is composed of a stack of filter membranes folded continuously back and forth, if stacked front and back, further As a result, the air resistance increases, and the temperature adjustment speed of the air conditioner is slower, especially when the air humidity in the indoor environment is high and the concentration of particulate matter is high. increase, which in turn leads to a series of adverse effects such as the attenuation of heat exchange efficiency of the air conditioner, the increase of motor power, and the increase of motor heat.
