Embodiment

[0024] The solution of the present invention is further described by taking the tof module as an example of the ranging module.

[0025] tof is a technology to measure the distance of the target object by measuring the time of flight of the light wave. It can judge the distance between the object and the transmitting end by the elapsed time of directional emission of light and receiving the signal reflected back. When the ranging light is emitted by dot matrix scanning, the high-frequency tof module can even return the point cloud image of the imaging plane.

[0026] We combine the tof module with the household mixer. Since the movement of the solid / liquid / solid-liquid mixture in the household mixer is eddy current along the container wall, we can observe the change of the tof signal sent to the container wall ( Solid / liquid / solid-liquid mixture, the resulting tof signal is blocked / interferenced / refracted, etc.) to determine whether its content exceeds the upper limit of the m...

Abstract

The invention relates to the field of household electrical appliances, and discloses a household automatic speed-regulating mixer and a control method thereof, which solves the problem that the existing household mixer cannot perform automatic stepless speed regulation and is not intelligent enough. The mixer includes a controller, a motor and a ranging module, the ranging module and the motor are electrically connected to the controller; the ranging module is used to detect the distance information of the detection area on the inner wall of the mixer container and transmit the detected distance information to the controller The controller is used to establish a model for calibrating the detection area by using the distance information detected by the ranging module when the mixer system is started. After the system is started, the distance information detected by the ranging module is compared with the model to judge the mixer container. Whether the edge height of the content in the container reaches the lower limit height of the detection area, if so, the control motor maintains the current speed, if not, the control motor increases step by step until the upper edge height of the content in the mixer container reaches the lower limit height of the detection area.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a household automatic speed-regulating mixer and a control method thereof. Background technique [0002] The existing mixing machines are manually set the gear level, and cannot automatically detect whether the speed is reasonable. Especially for liquids, the difference in the amount of liquid loaded in the same container often affects the effect of the same gear. For example, for the same container, if there is less liquid loaded, a higher gear can be used to improve the stirring efficiency, but if the liquid is loaded more, Stirring with this gear may cause the content to overflow. In order to avoid the overflow of the content, the existing mixer usually adopts a gear with a lower speed, which will affect the stirring efficiency. [0003] In addition, household mixers are often used to mix objects such as fruits. When the objects are converted from solid state, solid-liquid...
