Embodiment 1

[0048] In order to achieve the above-mentioned technical purpose, the present invention provides a human body detection method for a washing machine, including an infrared sensor arranged on the washing machine, and a control part arranged in the washing machine, such as figure 1 As shown, the human detection method includes:

[0049] 11. The operation department obtains the temperature value within the detection range of the washing machine in real time;

[0050] 12. Compare the obtained temperature value with the preset threshold value, and judge whether someone is close to the washing machine according to the comparison result;

[0051] 13. If it is determined that someone is approaching the washing machine, obtain the current running state of the washing machine, and make the control unit control the backlight of the washing machine according to the running state.

[0052] For the sake of integrated aesthetics, when this type of washing machine is powered off or not runni...

Embodiment 2

[0095] In the previous embodiment, the step of detecting the human body based on the infrared sensor is proposed. Based on the content of the foregoing embodiment, this embodiment also proposes an update step of obtaining the temperature value within the detection range of the washing machine, as shown in figure 2 As shown, the update steps include:

[0096] Step 1: Construct the initial temperature values ​​T0 and T1 to obtain the real-time temperature T of the environment where the washing machine is located;

[0097] Step 2, determining the difference ΔT1 between the real-time ambient temperature T and the initial temperature T1;

[0098] Step 3, if the difference ΔT1 is greater than the preset threshold Th1, the human body detection result function F is assigned a value of 1, indicating that a human body is close to the washing machine, the value of the initial temperature value T1 is updated to T, and the value of T0 remains unchanged.

[0099] Step 4, if the difference...

Abstract

The invention provides a human body detection method for a washing machine and belongs to the field of washing machines. Including that the operation part obtains the temperature value within the detection range of the washing machine in real time; compares the obtained temperature value with the preset threshold value, and judges whether someone is close to the washing machine according to the comparison result; The backlight of the washing machine is controlled according to the operating state. By detecting the human body, and based on the detection results combined with the current state of the washing machine, the backlight of the washing machine operation part is adjusted so that when the human body is far away from the washing machine, the backlight of the power button is turned on, and when the human body is far away from the washing machine, the lit backlight is turned on. When the indicator light is off, while saving electricity, there is no need to use other methods to divide the functions of the operating part area, so as to maintain the integrity of the appearance of the washing machine.

Description

technical field [0001] The invention belongs to the field of washing machines, in particular to a human body detection method used in washing machines. Background technique [0002] Due to the market demand for home decoration integration, washing machines all use hidden operation panels. Although this type of operation panel achieves a high overall aesthetic effect, it also brings problems that users cannot accurately determine the control buttons when the panel backlight is off. location this flaw. [0003] Although the approximate operating range can be delineated by screen printing on the operating panel, the overall effect of the operating panel of the washing machine is destroyed. Contents of the invention [0004] In order to solve the shortcomings and deficiencies existing in the prior art, the present invention provides detection of the human body through the detection results of the infrared sensor, and then controls the indicator lights in the washing machine, ...
