[0029] In order to make the purpose, technical solution and advantages of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0030] like Figure 1 As shown, a washing machine according to an embodiment of the present invention comprises a washing machine body 100, a washing machine inner barrel 110 disposed in the washing machine body 100 and used for assembling washing clothes 200, as shown in FIG. Figure 2 As shown, it also includes:

[0031] The infrared detection module 120 disposed above the washing inner tub 110 is used to emit infrared rays, and to perform all-terrain detection of the clothes placed in the washing inner tub 110 through the emitted infrared rays, so as to detect the height data of the clothes in the washing inner tub 110;

[0032] The circuit board 130 disposed on the washing machine body 100 is connected to the infrared detection module 120. Figure 4 As shown, it is used to receive the clothing height data of the washing inner barrel 110 detected by the infrared detection module 120, and generate an opening or closing signal to send to the water inlet valve module according to the detected clothing height data of the washing inner barrel 110;

[0033] The water inlet valve module 140 disposed on the washing machine body 100 is connected to the circuit board 130. Figure 4 As shown, it is used to receive the opening or closing signal sent by the circuit board 130 to open or close the water filling in the washing tub;

[0034] A pressure water level sensor 150 is disposed on the side wall of the washing inner tub 110 , and is connected to the circuit board 130 , for detecting the water level of the washing inner tub 110 and sending the detected water level signal to the circuit board 130 .

[0035] like Figure 1 , Figure 2 and Figure 4 As shown, the infrared detection module 120 in the embodiment of the utility model is used to emit infrared rays, and perform all-round detection of the clothes in the washing inner drum through infrared rays. Among them, the clothes placed in the washing inner drum 110 are detected in all terrains. Specifically, the height data of the clothes in the washing inner drum can be detected through the emitted infrared rays, thereby realizing all-round and all-terrain detection.

[0036] In the embodiment of the utility model, the height data of the clothes in the washing inner drum 110 can be detected, specifically by reflection and reception of infrared rays, so as to obtain the height data of the clothes in the washing inner drum for subsequent water inlet control.

[0037] For example, in the embodiment of the utility model, when clothes of different heights are placed in the washing machine, the infrared detection module can identify the height of the clothes according to the reflection by emitting infrared rays, thereby obtaining accurate clothes height data.

[0038] The utility model adopts an infrared detection module to achieve all-round automatic detection without manual intervention by the user, thus improving the intelligence level of the washing machine. By obtaining accurate clothing height data, the system can accurately control the parameters in the washing process according to actual conditions and improve the washing effect. In addition, the infrared detection module can detect clothing of different shapes and sizes, and has a wide range of applications.

[0039] In the embodiment of the utility model, the circuit board 130 provided on the washing machine body 100 can be specifically: a main control board inside the washing machine, which is usually used to process various sensor data and control the actuator action. In this embodiment, a connection is established between the circuit board 130 and the infrared detection module 120, which is used to receive the clothing height data of the washing inner barrel 110 detected by the infrared detection module. And the circuit board 130 will make corresponding control decisions based on the received clothing height data. For example, the circuit board 130 will control the water inlet valve module so that the water intake matches the clothing height data to achieve an appropriate water level.

[0040] In an embodiment of the utility model, if the infrared detection module detects a large amount of clothes in the washing drum and detects the height data of the clothes, the circuit board will instruct the water inlet valve module to open and let water in to an appropriate water level to ensure that the clothes can be fully soaked and effectively cleaned.

[0041] In the embodiment of the utility model, the water intake can be controlled according to the clothing height data detected by the infrared detection module, thereby avoiding unnecessary waste of water resources and improving the energy-saving efficiency of the washing machine. By controlling the water level, it is ensured that the washing liquid is in full contact with the clothing, thereby improving the washing effect. In addition, the circuit board realizes automatic control, which reduces the user's operating burden, improves the user experience, and enables the washing machine to make more intelligent adjustments during the washing process, thereby improving the level of intelligence.

[0042] In the embodiment of the utility model, the water volume is regulated through a water inlet valve module 140, which is used to control the amount and flow rate of water inlet. The water inlet valve module 140 is connected to the circuit board 130 in the washing machine, so that the water inlet valve can be opened or closed according to the instructions issued by the circuit board, thereby adjusting the water level in the washing machine.

[0043] Specifically, the circuit board 130 of the embodiment of the utility model will send a water level signal to the water inlet valve module 140. This signal tells the water inlet valve how long to open or close in order to control the water level in the washing machine. If the washing machine needs to increase the amount of water, the circuit board 130 will send a signal to the water inlet valve module 140, and 140 will open it for a longer time to allow more water to enter the washing machine; conversely, if the amount of water needs to be reduced, the circuit board 130 will send a command to close the water inlet valve module 140 to stop the water inlet.

[0044] In this way, the connection between the water inlet valve module 140 and the circuit board 130 of the utility model realizes the precise control of the water level of the washing machine, ensures that the water level matches the height of the clothes, improves the washing effect and saves water resources.

[0045] The circuit board 130 detects whether the water level matches the height of the clothes, and sends a water level signal to the water inlet valve module 140. The water inlet valve module controls the switching state of the water inlet valve according to the signal, and adjusts the water level in the washing machine to ensure that the water level matches the height of the clothes, thereby achieving a balance between the best washing effect and water resource utilization.

[0046] In the embodiment of the utility model, the pressure water level sensor 150 is arranged on the side wall of the washing inner tub 110. This is a sensor installed on the inner wall of the washing tub for detecting changes in water level height.

[0047] In this embodiment, the pressure water level sensor 150 is connected to the circuit board 130 through a signal line such as an electric wire, and transmits the detected water level information to the circuit board. In the utility model, during the laundry process, the pressure water level sensor 150 will continuously monitor the change of the water level. The sensor will detect whether the water level matches the height of the clothes in the laundry tub to ensure the best balance between the washing effect and the use of water resources. If the water level matches the height of the clothes, the sensor will send a signal to the circuit board, and vice versa.

[0048] This has the following benefits for ensuring washing results and water resource utilization:

[0049] 1) Improve washing effect: Matching the water level with the height of the clothes can ensure that the detergent and water can effectively cover the surface of all clothes, making the cleaning more thorough and removing stains more effective.

[0050] 2) Save water resources: By accurately controlling the water level, ensuring that the amount of water used is sufficient but not wasted, the purpose of saving water resources can be achieved. The problem of water waste caused by too high or too low water level can be avoided.

[0051] 3) Reduce energy consumption: Adjusting the water level according to actual needs can avoid additional energy consumption and thus improve the energy efficiency performance of the washing machine.

[0052] 4) Improve user experience: Ensure that the water level matches the height of the clothes, making the cleaning process more intelligent and efficient, and improving the user experience.

[0053] It can be seen that the utility model can achieve the best balance between washing effect and water resource utilization by allowing the sensor to detect the matching degree between the water level height and the clothing height, thereby improving the washing effect, saving resources, reducing energy consumption, and enhancing the user experience.

[0054] If there are too few clothes in the washing machine, the pressure water level sensor will detect that the water level is low. In this embodiment of the utility model, a signal will be sent to the circuit board to request an increase in the water intake to ensure that the water level matches the height of the clothes and improve the washing effect.

[0055] The utility model can effectively improve the washing effect and make washing more thorough by ensuring that the water level matches the height of the clothes. The water level can be adjusted according to actual needs to avoid unnecessary water resource consumption and improve the energy-saving performance of the washing machine. The water level change can be monitored in real time, and the water intake can be automatically adjusted to improve the intelligence of the washing process.

[0056] Furthermore, the washing machine of the utility model embodiment, such as Figure 2 and Figure 3 As shown, the infrared detection module 120 includes:

[0057] The infrared detection head 121 is used to send out infrared detection signals to perform all-terrain detection on the clothes placed in the washing inner drum 110, and convert the received returned infrared radiation signals into detection electrical signals;

[0058] A filter amplifier 124 connected to the infrared detection head 121, used to amplify the detection electrical signal received by the infrared detection head;

[0059] The processing module 123 connected to the filter amplifier 124 is used to process the amplified detection electrical signal into clothing height data of the washing inner drum 110 .

[0060] In this embodiment, the infrared detection head 121 is a component for emitting infrared detection signals and then receiving returned infrared radiation signals. When the infrared detection signals are irradiated on the clothes in the washing inner tub 110, some of the signals will be absorbed by the clothes and some will be reflected. The infrared detection head 121 will receive these returned signals.

[0061] The embodiment of the utility model uses a filter amplifier 124, which is connected to the infrared detection head 121. Its function is to amplify the signal received by the infrared detection head, and it can also filter to remove interference signals to ensure that only important information is transmitted.

[0062] This embodiment uses a processing module connected to the filter amplifier 124 to further process the amplified detection electrical signal. In this case, the function of the processing module 123 is to process the signal into height data of the clothes in the washing inner drum 110. This module may apply some algorithms or logic to convert the signal and then output the data in the form of height.

[0063] It can be seen that the utility model realizes the detection and measurement of the height of the clothes in the washing machine through infrared technology. Through the synergy between different components, the infrared signal is transmitted and received, then amplified, filtered and processed, and finally converted into accurate data of the height of the clothes in the washing drum.

[0064] In the embodiment of the utility model, preferably, the infrared detection module 120 is arranged at the top center above the washing inner tub 110, so as to facilitate all-terrain detection of the clothes in the washing inner tub 110 to more accurately detect the height data of the clothes.

[0065] In the embodiment of the utility model, preferably, the infrared detection module 120 is arranged at the lower center of the washing machine cover 160 , corresponding to the top of the washing machine inner barrel 110 .

[0066] In the embodiment of the utility model, the infrared detection module 120 is arranged at the lower center of the washing machine cover and above the washing inner drum, which helps to ensure that the detection head faces the inside of the washing inner drum 110, and can more accurately detect the height of the clothes in the washing inner drum. At the same time, the infrared detection module 120 is arranged above the washing inner drum 110 to effectively avoid blind spots, ensuring that the detection head can completely cover the entire washing inner drum area, so that the height of the clothes can be fully and accurately detected.

[0067] That is, in the embodiment of the utility model, the infrared detection module 120 is set at a position above the washing inner barrel to ensure that the infrared detection module can fully detect the clothes inside the washing inner barrel, thereby improving the accuracy and reliability of the measurement. And errors can be avoided: by avoiding blind spots, setting it in a suitable position can reduce errors caused by improper angles or blind spots, thereby ensuring the accuracy of the data. It also has the advantage of being easy to install and maintain, that is, setting the infrared detection module at the lower central position of the washing machine cover, which can make installation and maintenance more convenient and simple, and improve the operability of the system.

[0068] Furthermore, the washing machine described in this embodiment, as Figure 1 and Figure 2 As shown, the water inlet valve module 140 is arranged above the side of the washing machine body 100 to facilitate the control of water inlet.

[0070] Furthermore, the washing machine described in this embodiment, as Figure 1 and Figure 2 As shown, a control panel 170 is disposed above the washing machine body 100 , and the control panel 170 is connected to the circuit board 130 .

[0071] Furthermore, the washing machine described in this embodiment, as Figure 1 and Figure 2As shown, a mounting groove 171 is provided on the washing machine body 100 corresponding to the lower portion of the control panel 170 , and the circuit board 130 is mounted on the mounting groove 171 , which can effectively prevent the circuit board 130 from being wetted by water.

[0072] Furthermore, the washing machine described in this embodiment, as Figure 1 and Figure 2 As shown, the pressure water level sensor 150 is arranged on the lower side of the washing inner barrel 110, so as to detect the water level in time according to the water pressure in the washing inner barrel.

It is convenient to perform similar all-terrain detection of clothing height distance identification, so as to identify the highest distance of clothing. The water level height is automatically controlled by the laundry device to achieve the optimal water usage.

[0074] The infrared detection module 120 of the embodiment of the present invention detects the height of the clothes by infrared, collects data signals and transmits them to the circuit board, compares the data and feeds the results back to the main control chip of the circuit board, transmits the water level signal to control, and sends it to the water level sensor to control the water level.

[0075] The water level sensor detects the washing process. During the first washing process, the height of the clothes and the water level are detected to see if they meet the requirements. If they do not meet the requirements, they can be re-detected for matching.
