specific Embodiment 1

[0031] Such as Figure 1-3 As shown, the washing machine 1 of this embodiment is equipped with an infrared detection device. The infrared detection device includes an infrared sensor 2 and a signal processing circuit. The infrared sensor 2 is connected to the controller of the washing machine through the signal processing circuit. Infrared sensor 2 detects whether there are infrared rays corresponding to the wavelength of the human body temperature range in the mouth of the laundry tub or in the laundry tub. The device controls the washing machine to stop running according to the received detection signal.

[0032] Specifically, the signal processing circuit includes an amplification circuit, a filter circuit and a comparison circuit. When the infrared sensor does not receive the infrared rays corresponding to the wavelength of the human body temperature range, the infrared sensor 2 has no current signal output, the signal processing circuit outputs a low-level signal, and th...

specific Embodiment 2

[0035] This embodiment is aimed at a washing machine with a water heating function. In order to prevent the warm water close to the temperature of the human body from interfering with the detection of the infrared sensor, it is necessary to limit the range of infrared rays received by the infrared sensor.

[0036] Such as Figure 4 As shown, the present embodiment takes the pulsator washing machine as an example, and an infrared detection device is embedded in the frame of the pulsator washing machine 1. The infrared detection device includes a cover body 3, and the infrared sensor 2 is installed in the cover body 3. The cover body 3 A light collection window facing the mouth of the washing tub is arranged on the top, and the cover body 3 limits the light collection range of the infrared sensor 2, and the infrared sensor 2 only receives infrared rays through the light collection window. In this embodiment, the infrared sensor 2 receives light in a range of θ°, and the lowest p...

specific Embodiment 3

[0042] This embodiment is aimed at a washing machine with a water heating function. In order to avoid the interference of warm water close to the temperature of the human body on the detection of the infrared sensor and minimize the detection dead angle of the infrared sensor, it is necessary to limit the range of the infrared sensor receiving infrared rays, and the infrared sensor The range of receiving infrared rays can be adjusted.

[0043] Such as Figure 7-8 As shown, the washing machine of this embodiment includes a water level sensor and an infrared detection device. Wherein, the water level sensor is used to detect the water level in the washing tub 4; the infrared detection device includes a cover body 3, a drive mechanism 5 and an infrared sensor 2 located in the cover body 3, the drive mechanism 5 is located at one end of the cover body 3, and the infrared sensor 2 is installed At the moving end of the driving mechanism 5, the other end of the cover body 3 is provi...

Abstract

The invention relates to a washing machine and a control method thereof. An infrared detection device is mounted on the washing machine, the infrared detection device comprises an infrared sensor, and the infrared sensor is connected with a controller through a signal processing circuit. The infrared sensor is used for detecting whether the infrared ray of the wavelength corresponding to the human body temperature range exists in a washing tub opening or in a washing tub. When the infrared ray is detected, detection signals are generated and transmitted to the controller, and the controller sends control signals for controlling the operation of the washing machine. According to the washing machine and the control method thereof, the infrared detection device is used for detecting whether a human body is in the washing tub, the washing machine is controlled to stop running immediately when the human body in the washing tub is detected, so that the damage to the human body due to the continues running of the washing machine can be avoided, and the potential safety hazard of the washing machine can be eliminated completely.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to a washing machine capable of automatically detecting whether there is a person in the washing machine and a control method thereof. Background technique [0002] Along with the raising of people's living standard, washing machine is widely used in the middle of people's daily life. While washing machine brings convenience to people's life, there is also certain potential safety hazard. In recent years, washing machine injuries have occurred frequently. The main reasons are as follows: First, there are illegal operations when adults use washing machines. During the washing process, users directly open the washing machine cover and put their hands Extending into the washing machine tub for operation, but the washing machine does not stop in time, causing harm to the human body; second, when children are playing, they enter the washing machine, and when the chi...
