[0032] In addition, the technical features involved in the different embodiments of the utility model described below can be combined with each other as long as there is no conflict.

[0033] With the development of technology, washing machines are becoming more and more popular in life. The traditional washing machine needs the user to manually select the washing program, including water temperature, washing time and washing mode, etc., which depends on the subjective judgment of the user on the material and stain degree of the clothes, and may cause damage to the clothes or incomplete cleaning due to the selection of unsuitable washing program.

[0034] The washing machine in the related art adopts a basic sensor, such as a temperature sensor and a humidity sensor, to monitor the washing environment, and then selects a corresponding washing program for washing. However, this scheme is not comprehensive enough for the collection of clothes information, which affects the accuracy of the selection of the washing program, and further affects the washing efficiency and effect.

[0035] Therefore, the utility model embodiment provides a washing machine, which collects clothes information comprehensively by combining a quantum dot spectrum sensor and a weight sensor, and improves the washing efficiency and effect.

[0036] Figure 1 is a structure diagram of the washing machine according to the utility model embodiment. As Figure 1 shown, in the washing machine, it includes washing machine door shell 1, washing machine barrel 2, quantum dot spectrum sensor 4, light source 5, weight sensor 6 and controller 7.

[0037] The washing machine tub 2 comprises a containing cavity with an open side for placing the laundry 9. The washing machine door housing 1 is used to seal the opening of the washing machine tub 2. The light source 5 is installed on the washing machine door housing 1, which is used to irradiate the laundry 9 in the washing machine tub 2. The quantum dot spectrum sensor 4 is installed on the washing machine door housing 1, which is used to receive the spectrum information reflected and / or scattered by the laundry 9 after being irradiated by the light source 5. The quantum dot spectrum sensor is used to identify the spectrum information at least characterizing the material and color of the laundry 9. The weight sensor 6 is arranged at the bottom of the washing machine tub 2, which is used to measure the weight of the laundry 9. The controller 7 is electrically connected with the light source 5, the quantum dot spectrum sensor 4, the washing machine tub 2 and the weight sensor 6 respectively.

[0038] Figure 1 The working principle of the washing machine is as follows:

[0039] The light source 5 can emit light of a specific wavelength for illumination and excitation of quantum dots. By selecting light sources 5 of different wavelengths, different materials or colors of clothes can be illuminated, thereby improving the accuracy of detection. For example, it can be used for color detection, while light sources 5 of specific wavelengths can be used to excite certain specific fluorescent properties or for substance analysis. Quantum dots are a kind of nanoscale semiconductor material with unique optical properties, capable of emitting light at a specific wavelength. Based on this, the quantum dot spectral sensor 4 can perform high-precision analysis on the wavelength of incident light, identify the spectral characteristics of different substances. Specifically, when the light source 5 irradiates the surface of the object to be cleaned 9, the object to be cleaned 9 will reflect, absorb or scatter light. The quantum dot spectral sensor 4 receives these reflected and / or scattered light, obtains the spectral information of the reflected and / or scattered light after the light source 5 irradiates the object to be cleaned 9, identifies the spectral information at least representing the material and color of the object to be cleaned 9 and converts it into an electrical signal to send to the controller 7. The controller 7 can receive the spectral information transmitted by the quantum dot spectral sensor 4 and analyze it through the built-in algorithm to identify the color, material, stains and color difference on the clothes of the object to be cleaned 9, and then determine the required washing speed and washing time, etc. The weight sensor 6 can obtain the pressure value according to the pressure applied by the washing machine barrel 2 to the bottom, and then obtain the weight data of the object to be cleaned 9 in the washing machine barrel 2 and convert it into an electrical signal to send to the controller 7. The controller 7 can receive the weight data transmitted by the weight sensor and determine the number and type of the object to be cleaned 9 through the built-in algorithm, and then determine the required water and detergent usage, etc. Combined with the spectral information transmitted by the quantum dot spectral sensor 4 and the weight data transmitted by the weight sensor 6, the controller 7 can comprehensively determine the color, material, stains and weight of the object to be cleaned 9, and then select the appropriate washing program and send the corresponding washing instructions to the washing machine barrel 2 for the washing machine barrel 2 to perform the washing operation on the object to be cleaned 9 according to the received washing instructions. Among them, the washing program includes the required water, detergent usage, washing water temperature, washing speed and washing time, etc. Correspondingly, the washing instructions also include the required water, detergent usage, washing water temperature, washing speed and washing time, etc.

[0040] By accurately identifying the color, material, stain level and weight of the object to be cleaned, the system can recommend the most suitable washing program, improve washing efficiency and effect, and protect the object to be cleaned and prolong its service life. Adjusting the water and detergent usage according to the weight and stain level of the object to be cleaned can effectively reduce the consumption of water resources and detergents, save energy and detergents, and protect the environment.

[0041] For example, when the user needs to wash the laundry 9, the laundry 9 is placed in the accommodation cavity of the washing machine barrel 2, and the washing machine is turned on. The light source 5 irradiates the laundry 9 in the washing machine barrel 2 with light of a preset wavelength, and the quantum dot spectrum sensor 4 can capture the light reflected and / or scattered by the laundry 9 after being irradiated by the light source 5 to obtain spectrum information and send the spectrum information to the controller 7. At the same time, the weight sensor 6 measures the weight data of the laundry 9 in real time and sends the weight data to the controller 7. The controller 7 receives the spectrum information and the weight data, and selects a suitable washing program according to the spectrum information and the weight data through an algorithm with a washing program selection function built-in, and sends corresponding washing instructions to the washing machine barrel 2 for the washing machine barrel 2 to perform washing operations according to the washing instructions.

[0042] It should be noted that the algorithm programs involved in the acquisition of spectrum information by the quantum dot spectrum sensor 4, the measurement of weight data by the weight sensor 6, and the selection of the washing program by the controller 7 are all algorithm programs with corresponding functions in the related art, and these algorithm programs are not the innovative points of the present application.

[0043] Optionally, the light source 5 includes a plurality of LED lamps of different wave bands, and the light emitted by the light source 5 has a wavelength range including near-infrared light of 780-2526 nm and visible light of 390-780 nm.

[0044] In an optional embodiment, the washing machine further includes a display unit 8 arranged outside the washing machine door shell 1, and the display unit 8 is electrically connected to the controller 7. The display unit 8 includes a display screen and a corresponding operation mechanism. The user can view the washing conditions and washing program suggestions provided by the washing machine through the display screen of the display unit 8, such as whether the washing machine is turned on, whether the washing machine is working normally, whether the washing machine barrel is empty, the color of the laundry, the material of the laundry, the degree of dirt of the laundry, the weight of the laundry, the recommended amount of washing water, the recommended amount of washing liquid, the recommended washing water temperature, the recommended washing speed, the recommended washing time, the current recommended washing mode, etc., and perform the required operations through the operation mechanism, such as turning on the washing machine, starting the washing program, pausing the washing, increasing the washing time, changing the amount of washing liquid, etc. The operation mechanism can be a button or a touch screen. When the operation mechanism is a physical button, the display unit 8 further includes a plurality of physical buttons for providing interaction between the user and the display unit 8, such as a power button, a start / pause washing button, a washing time setting button, and a washing liquid amount setting button. When the operation mechanism is a touch screen, the display screen of the display unit 8 has a touch screen function, and the display screen includes a plurality of virtual buttons for providing interaction between the user and the display unit 8, which have similar functions to the physical buttons and will not be described here.

[0045] In an alternative embodiment, the quantum dot spectrum sensor 4 and / or the light source 5 are arranged towards the accommodating cavity. Arranging the light source 5 towards the accommodating cavity can directly irradiate the washing object 9 in the accommodating cavity, and arranging the quantum dot spectrum sensor 4 towards the accommodating cavity can directly receive the spectrum information reflected and / or scattered by the washing object 9 after being irradiated by the light source 5. The quantum dot spectrum sensor 4 and / or the light source 5 can also not be arranged towards the accommodating cavity, for example, at least one mirror is arranged so that the light source 5 irradiates the light emitted towards the accommodating cavity through the mirror and / or the quantum dot spectrum sensor 4 receives the spectrum information through the mirror.

[0046] In an alternative embodiment, the quantum dot spectrum sensor 4 comprises a detector and a quantum dot filter arranged on the receiving side of the detector. The detector can capture the light signal reflected and / or scattered by the washing object 9 after being irradiated by the light source 5, measure the intensity and wavelength of the light signal, and convert it into an electrical signal for subsequent spectrum analysis. The quantum dot filter can selectively filter light of a specific wavelength based on the characteristics of quantum dots that produce different energy intervals due to differences in size and composition, and enhance the light signal in a specific wavelength range through the quantum confinement effect of quantum dots, thereby improving the signal-to-noise ratio and enabling the detector to more accurately measure the light signal.

[0047] In an alternative embodiment, the inside of the washing machine door shell 1 is further provided with an internal cavity, the internal cavity has a light-transmitting cavity wall facing the accommodating cavity, the light source 5 and the quantum dot spectrum sensor 4 are sealed in the internal cavity, and the emitting end of the light source 5 and the receiving end of the quantum dot spectrum sensor 4 face the light-transmitting cavity wall. By sealing the quantum dot spectrum sensor 4 and the light source 5 in the internal cavity, the quantum dot spectrum sensor 4 and the light source 5 can be prevented from being flooded. By arranging the light-transmitting cavity wall and arranging the emitting end of the light source 5 and the receiving end of the quantum dot spectrum sensor 4 towards the light-transmitting cavity wall, the light source 5 can be ensured to irradiate the washing object 9 in the accommodating cavity through the light-transmitting cavity wall, and the quantum dot spectrum sensor 4 can be ensured to receive the spectrum information reflected and / or scattered by the washing object 9 after being irradiated by the light source 5 through the light-transmitting cavity wall.

[0048] In an alternative embodiment, the accommodating cavity is connected with a water inlet channel, the water inlet channel is provided with a first flow control valve, and the first flow control valve is signal connected with the controller 7. The controller 7 can send an instruction for controlling the water quantity to the first flow control valve, and the first flow control valve can control the opening or closing of the water inlet channel according to the received instruction for controlling the water quantity to control the water quantity entering the accommodating cavity.

[0049] In one optional embodiment, the receiving cavity is connected to a washing liquid inlet channel, and a second flow control valve is provided on the washing liquid inlet channel. The second flow control valve is signal-connected to the controller 7. The controller 7 can send a command to the second flow control valve to control the amount of washing liquid. The second flow control valve controls the opening or closing of the washing liquid inlet channel according to the received command to control the amount of washing liquid entering the receiving cavity.

[0050] In one alternative embodiment, the washing machine also includes a washing machine door glass 3, which is embedded in the washing machine door housing 1 so that the user can view the contents 9 to be washed inside the washing machine tub 2 through the washing machine door glass 3.

[0051] In one optional embodiment, the washing machine tub 2 has a horizontal tub structure; or, the washing machine tub 2 has a vertical tub structure. The structure of the washing machine tub 2 can be set according to actual needs. It should be noted that the weight sensor 6 is located at the bottom of the washing machine tub 2, meaning it is located below the washing machine tub 2 in the direction of gravity, so as to measure the weight of the item 9 to be washed.

[0052] In one optional embodiment, the washing machine further includes a color-blocking device for clothes. Figure 1 (Not shown in the image), it is installed inside the washing machine drum 2. The garment anti-color-crossing sheet placement module includes a placement area for placing garment anti-color-crossing sheets.

[0053] In an alternative embodiment, the clothing anti-color-crossing sheet placement module also includes an electric door electrically connected to the controller 7, and the quantum dot spectral sensor 4 is also used to identify spectral information characterizing the color of the liquid in the containment cavity.

[0054] The quantum dot spectral sensor 4 can identify the spectral information characterizing the color of the liquid in the containment cavity and transmit it to the controller 7. When the controller 7 detects a change in the color of the liquid in the washing machine tub 2, it sends a command to the electric door of the anti-color-crossing sheet placement module to open the electric door and place the anti-color-crossing sheet from the placement area of ​​the module into the washing machine tub 2 to prevent color crossing between clothes. It should be noted that the algorithm program of the controller 7 for identifying the liquid color and controlling the electric door uses an algorithm program with corresponding functions in related technologies, and this algorithm program is not the inventive point of this utility model.
