Embodiment 1

[0049] This embodiment provides a control system for automatically adjusting the motor speed, such as figure 1 and figure 2 Shown:

[0050] According to a preferred implementation mode, the control system for automatically adjusting the motor speed in the embodiment of the present invention includes: a detection device 3 and a control device 1 . Wherein: the detection device 3 is connected with the control device 1, and the detection device 3 is used to detect the size of the air inlet or the size of the air outlet during the operation of the electrical appliances driven by the motor 2. The control device 1 is electrically connected to the motor 2, and the control device 1 can adjust the rotation speed of the motor 2 according to the detection result of the detection device 3, so as to keep the air output during the operation of the electrical appliance stable.

[0051] According to a preferred embodiment, the control device 1 is electrically connected to the motor 2, and the...

Embodiment 2

[0061] This embodiment provides a control method for automatically adjusting the motor speed, such as image 3 and Figure 4 Shown:

[0062] According to a preferred implementation mode, the control method for automatically adjusting the motor speed in the embodiment of the present invention is implemented by using the control system for automatically adjusting the motor speed in any technical solution of the present invention.

[0063] According to a preferred embodiment, the control method for automatically adjusting the motor speed includes the following steps:

[0064] S1: output rated air volume F1. Preferably, the control device 1 controls the rotation speed of the motor 2 based on the wind speed F0 selected by the user and outputs a rated air volume F1 through the air duct.

[0065] S2: Detect the air supply angle. Preferably, the detection device 3 detects the air supply angle of the air duct in real time.

[0066] S3: Determine the compensation wind speed F2. Pr...

Abstract

The invention discloses a control system for automatically adjusting the motor rotating speed, a household appliance and a control method, and relates to the technical field of household appliances. The technical problem that the air outlet quantity of a household appliance in the prior art is instable is solved. The control system for automatically adjusting the motor rotating speed comprises a detecting device and a control device, the detecting device is connected with the control device, and the detecting device is used for detecting the size of an air inlet or the size of an air outlet inthe process that a motor drives the electric appliance to work; and the control device is electrically connected with the motor and can adjust the rotating speed of the motor according to a detectingresult of the detecting device so that the air outlet quantity can keep stable in the working process of the electric appliance. The control system can adjust the rotating speed of the motor based onthe size of the air inlet or air outlet, and therefore the air outlet quantity of the household appliance in the working process keeps stable.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a control system for automatically adjusting the rotational speed of a motor, a household appliance and a control method. Background technique [0002] The fan in the prior art realizes the function of supplying air at different angles in the horizontal direction by controlling the rotation of the air duct assembly. However, during the rotation of the air duct assembly, the size of the air inlet will change accordingly, resulting in unstable output air volume and wind noise. Big and small, generating noise, affecting user comfort and reducing user experience. [0003] For this reason, providing a control system, a control method and a household appliance using the control system that can automatically adjust the motor speed based on different air supply angles has become a technical problem urgently to be solved by those skilled in the art.
