Problems solved by technology
Since the air resistance becomes larger after the IFD purification module is installed, in order to ensure the air volume requirement, the designer increases the speed of the indoor fan of the air conditioner, but when the user removes the IFD purification module, the air volume of the indoor fan of the air conditioner will be too large, and the noise level High, making the user experience worse

Embodiment Construction
[0038] figure 1 is a schematic structural block diagram of an air conditioner 10 according to an embodiment of the present invention, see figure 1 It can be known that the air conditioner 10 provided in an embodiment of the present invention may include an air conditioner indoor unit 100 . The air conditioner indoor unit 100 may include an air conditioner indoor fan 120 and at least one purification device 110 , and the purification device 110 is provided with an assembly structure 112 for installing a plurality of IFD purification modules 111 .
[0039] IFD (Intense Field Dielectric) refers to a strong electric field using a dielectric material as a carrier. The dielectric material forms a honeycomb hollow microchannel, and the electrode sheet of the conductive ink material is wrapped by the dielectric to form a strong electric field in the channel. After the air flows into the "honeycomb", the pre-charged dust particles are adsorbed on the inner surface of the hollow cavity...

The invention provides a rotation speed control method for an indoor fan of an air conditioner and the air conditioner. An indoor unit of the air conditioner comprises at least one purifying device which is provided with an assembly structure for mounting multiple IFD purifying modules. The method comprises the following steps: a current detecting step, wherein the indoor fan of the air conditioner is started with initial rotation speed, and operation current, under the initial rotation speed, of the indoor fan of the air conditioner is detected; an IFD purifying module mounting quantity judging step, wherein mounting quantity of IFD purifying modules is judged based on operation current; and a rotation speed control step, wherein rotation speed of the fan in the air conditioner is controlled according to a preset rotation speed control scheme which corresponds to the mounting quantity. According to the scheme adopted by the invention, the rotation speed control scheme can be selectedaccording to mounting quantity of the IFD purifying modules, so that intelligent control on rotation speed of the indoor fan of the air conditioner is realized; and moreover, while any IFD purifying module is not successfully assembled, power supply to the IFD purifying module is forbidden, an anti-electric shock protection function is realized, and safety is ensured, and therefore, the rotation speed control method is suitable for products such as intelligent electrical appliances and intelligent air conditioners.
Description
technical field [0001] The invention relates to the technical field of intelligent air conditioners, in particular to a method for controlling the speed of an indoor fan of an air conditioner and an air conditioner. Background technique [0002] With the continuous improvement of people's living standards, the quality of life is continuously improved, and there are higher requirements for the comfort of the living environment. For air conditioners, not only the cooling and heating effects are required, but also the air is healthy. According to the needs of users, major manufacturers Launched an air conditioner with IFD purification function. Since the air resistance becomes larger after the IFD purification module is installed, in order to ensure the air volume requirement, the designer increases the speed of the indoor fan of the air conditioner, but when the user removes the IFD purification module, the air volume of the indoor fan of the air conditioner will be too large,...
