Description

Technical Field

[0001] The present invention belongs to the technical field of washing equipment, and specifically relates to a method and a washing equipment system for feedback of exercise intensity based on a washing equipment. Background Art

[0002] After a person exercises, the body will generate a large amount of heat, and the body needs to dissipate heat by sweating. Therefore, a person will sweat after exercise. If the exercise intensity is high, the amount of sweat will be large. However, if a person sweats profusely even during mild exercise, it is necessary to consider whether it is caused by the external environment or a disease.

[0003] Therefore, the amount of sweat after a person exercises is an important basis for judging the exercise situation and exercise intensity.

[0004] Since the clothes after exercise are soaked with sweat stains and have an unpleasant smell, it is best to immediately use a washing equipment to wash the clothes. During the washing process, how the washing equipment obtains the amount of sweat stains in the clothes, objectively reflects the state of the human body after exercise through the amount of sweat stains, and judges the exercise situation and exercise intensity are technical problems to be solved at present.

[0005] In view of this, the present invention is specifically proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a method and a washing equipment system for feedback of exercise intensity based on a washing equipment. During the washing process with warm water without adding clothing treatment agents, since sweat stains are easily soluble in warm water, the stain index including the amount of sweat stains is detected. The amount of sweat stains discharged by the human body during exercise is reflected through the stain index, so that the stain index can objectively reflect the state of the human body after exercise, feedback a more objective and accurate exercise intensity to the user, help to perform exercise with a suitable intensity next time, and is beneficial to the healthy life of the user.

[0007] The basic concept of the technical solution adopted by the present invention to solve the above technical problem is as follows:

[0008] The present invention provides a method for feedback of exercise intensity based on a washing equipment, including the following steps:

[0009] Step S1: Wash with warm water without adding clothing treatment agents;

[0010] Step S2: During washing, detect the stain index including the amount of sweat stains for the warm water;

[0011] Step S3: Determine the exercise intensity according to the stain index;

[0012] Step S4: Feedback the exercise intensity to the user.

[0013] In the present invention, since sweat stains are easily soluble in warm water, during the washing process without adding laundry treatment agent with warm water, the stain index including the amount of sweat stains is detected, and the amount of sweat stains discharged by the human body during exercise is reflected by the stain index, so that the stain index can objectively reflect the state of the human body after exercise, feedback a more objective and accurate exercise intensity to the user, help to perform exercise with a suitable intensity next time, and is beneficial to the healthy life of the user.

[0014] A further solution of the present invention is that step S3 is specifically:

[0015] After determining the stain index range into which the stain index falls, determine the exercise intensity corresponding to the stain index range.

[0016] In the above solution, through the stain index range, the exercise intensity matching the amount of sweat stains in the stain index is better determined.

[0017] A further solution of the present invention is that the stain index range is specifically:

[0018] The washing device sets a first limit value less than a second limit value, and sets the range less than or equal to the first limit value as the low stain index range, sets the range greater than the first limit value and less than or equal to the second limit value as the medium stain index range, and sets the range greater than the second limit value as the high stain index range;

[0019] The low stain index range, the medium stain index range and the high stain index range respectively correspond to a gear of exercise intensity.

[0020] In the above solution, the accurate matching of the stain index and the exercise intensity is realized.

[0021] A further solution of the present invention is that in step S3, if it is determined that the stain index falls into the high stain index range, then in step S4, generate a suggestion message and feedback the exercise intensity and the suggestion message to the user.

[0022] In the above solution, it is realized to better help the user perform exercise with a suitable intensity, and feedback suggestion messages such as "it is recommended to reduce the amount of exercise next time" and "it is recommended to supplement salt reasonably" to the user, which is beneficial to the recovery after exercise and the healthy life of the user.

[0023] A further solution of the present invention is that the washing device is communicatively connected to the mobile device;

[0024] The washing device, and / or the mobile device, executes step S3 and step S4.

[0025] In the above solution, it is realized to better feedback the exercise intensity to the user through the washing device, and / or the mobile device.

[0026] A further solution of the present invention is that the washing device and the mobile device are communicatively connected;

[0027] The washing device, and / or the mobile device, receives a reservation instruction input by the user including an estimated end time point of the movement, and according to the reservation instruction, determines the time point for the washing device to generate warm water, and makes the warm water be used for the washing without adding laundry treatment agent in step S1.

[0028] In the above solution, it is realized that after the user's movement ends, the clothes can be immediately washed with warm water, ensuring the accuracy of the stain index including the amount of sweat stains detected.

[0033] A feedback module communicatively connected to the processing module for receiving the exercise intensity of the processing module and outputting the information of the exercise intensity;

[0034] Wherein, the stain index includes the amount of sweat stains.

[0035] A further solution of the present invention is that a storage module is used for storing data including stain index intervals and exercise intensity;

[0036] The processing module is used for judging the stain index interval into which the stain index falls and generating an exercise intensity corresponding to the stain index interval.

[0037] In the above solution, the system can implement the method for feedback of exercise intensity based on the washing device.

[0038] A further solution of the present invention is that the processing module is used for receiving the stain index of the optical detection module and generating an exercise intensity according to the stain index.

[0039] A further solution of the present invention is that the feedback module includes a washing device and / or a mobile terminal, and the feedback module is used for outputting the information of the exercise intensity through the washing device and / or the mobile terminal.

[0048] It should be noted that these drawings and text descriptions are not intended to limit the scope of the concept of the present invention in any way, but to illustrate the concept of the present invention to those skilled in the art by referring to specific embodiments. Specific Embodiments

[0049] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0050] Such as Figure 1 and 2As shown, the present invention provides a method and a washing equipment system for feedback of exercise intensity based on a washing equipment. Since sweat stains are easily soluble in warm water, during the washing process with warm water without adding laundry treatment agent, a stain index including the amount of sweat stains is obtained. This stain index can objectively reflect the state of the human body after exercise, and then feedback a more objective and accurate exercise intensity to the user, helping to perform exercise with an appropriate intensity next time, which is beneficial to the user's healthy life.

[0051] Embodiment 1

[0052] As Figure 1 and 2 As shown, this embodiment provides a method for feedback of exercise intensity based on a washing equipment, including the following steps: Step S1: Wash with warm water without adding laundry treatment agent; Step S2: During the washing, detect the stain index including the amount of sweat stains for the warm water; Step S3: Determine the exercise intensity according to the stain index; Step S4: Feedback the exercise intensity to the user.

[0053] Specifically, the stain index is a feedback variable obtained by detecting through optical sensor modules such as a near-infrared spectrum sensor and an ultraviolet spectrum sensor, preferably obtained through the ultraviolet spectrum sensor module. Further, the ultraviolet spectrum sensor uses the ultraviolet absorption spectrometry method for detecting the stain index. The ultraviolet absorption spectrometry method detects the stain index through the corresponding relationship between the substance and its ultraviolet-visible spectroscopy (UV-VIS) when the substance absorbs light of a specific wavelength to reach the maximum value. The electromagnetic wave wavelength corresponding to the ultraviolet spectrum sensor is shorter and has greater energy, which can penetrate tiny bubbles and has a better response to micron-sized particles. The stain index includes various substances that cannot be detected by conventional sensors. The conventional sensors such as an infrared pair tube sensor cannot detect organic soluble stains, including oily stains, proteins, laundry treatment agents, and emulsions, etc., while the ultraviolet spectrum sensor can detect the above organic soluble stains and can also detect insoluble particulate matters at the same time. Among them, the protein in the organic soluble stains includes sweat stains. Therefore, the ultraviolet spectrum sensor can better detect the stain index including the amount of sweat stains in the warm water without laundry treatment agent while having a larger detection range.

[0054] Further, compare and analyze the wavelength band of sweat stains in the ultraviolet-visible spectrum with the spectral band of the detected stain index in the ultraviolet-visible spectrum, so as to obtain a more accurate stain index of the amount of sweat stains.

[0055] Further, it is preferably an optical sensor for detecting the water stain index of the ultraviolet spectrum sensor, preferably arranged at the bottom of the inner barrel of a pulsator washing machine or a pulsator washer-dryer. During a set time before the drainage of the inner barrel starts, the stain index is detected multiple times, and the multiple detected stain indices are analyzed and processed to obtain a more accurate stain index.

[0056] Further, when no clothes are placed in the washing tub, the stain index collected by the ultraviolet spectrum sensor is received, and multiple stain indices are stored as historical data in the storage module. A stain index reference value is established based on the historical data. For example, the average value of the historical data is obtained as the stain index reference value. According to the stain index reference value, the stain index collected by the optical detection module when clothes are placed in the washing tub is corrected. For example, the stain index when clothes are placed in the washing tub is subtracted by the stain index reference value to obtain a corrected stain index.

[0057] Therefore, since sweat stains are easily soluble in warm water, during the washing process without adding laundry detergent with warm water, a stain index including the amount of sweat stains is obtained. This stain index can objectively reflect the state of the human body after exercise, and then feedback a more objective and accurate exercise intensity to the user, helping the user to perform appropriate-intensity exercise next time, which is beneficial to the user's healthy life.

[0058] In this embodiment, step S3 specifically is: after determining the stain index range into which the stain index falls, determine the exercise intensity corresponding to the stain index range.

[0059] Through the stain index range, the exercise intensity matching the amount of sweat stains in the stain index is better determined.

[0060] In this embodiment, the stain index range specifically is: the washing device sets a first limit value less than a second limit value, and sets the range less than or equal to the first limit value as the low stain index range, sets the range greater than the first limit value and less than or equal to the second limit value as the medium stain index range, and sets the range greater than the second limit value as the high stain index range; the low stain index range, the medium stain index range, and the high stain index range respectively correspond to a gear of exercise intensity.

[0061] The accurate matching of the stain index and the exercise intensity is achieved.

[0062] In this embodiment, in step S3, if it is determined that the stain index falls into the high stain index range, then in step S4, suggestion information is generated, and the exercise intensity and the suggestion information are fed back to the user.

[0063] It realizes better assistance for users to perform exercises with appropriate intensity and feeds back advice information such as "It is recommended to reduce the amount of exercise next time" and "It is recommended to supplement salt reasonably" to users, which is beneficial to the recovery after exercise and healthy living of users.

[0064] In this embodiment, the washing device and the mobile device are communicatively connected; the washing device, and / or the mobile device, execute step S3 and step S4.

[0065] In this embodiment, the mobile device is specifically an intelligent device with communication function, such as a smart phone, a smart bracelet, a smart voice speaker, a smart remote control screen, etc. The communication connection can be wired communication or wireless communication, and the wireless communication includes Bluetooth, WIFI network, infrared communication, etc.

[0066] It realizes better feedback of exercise intensity to users through the washing device and / or the mobile device.

[0067] In this embodiment, the washing device and the mobile device are communicatively connected; the washing device, and / or the mobile device, receive a reservation instruction input by the user including the expected exercise end time point, and according to the reservation instruction, determine the time point when the washing device generates warm water, and make the warm water be used for the washing without adding laundry agent in step S1.

[0068] As a specific implementation manner, the user can input a reservation instruction including the expected exercise end time point through the mobile device, for example, select and input a reservation instruction of the expected exercise end time point through the application program of the smart phone.

[0069] As another specific implementation manner, the user selects a sweat stain detection program through the control panel of the washing device and inputs a reservation instruction of the expected exercise end time point.

[0070] As another specific implementation manner, after the user sets the expected exercise end time point on the washing device, the user can modify the expected exercise end time point through the mobile device to update the reservation instruction so that it more conforms to the actual end time point.

[0071] Further, the washing device heats the connected tap water to a set temperature, for example, 37 degrees Celsius, to generate warm water. When the washing device is a washing machine or a washer-dryer for foreign trade models, since hot water is generated by a boiler in foreign laundries, the washing device can access hot water and mix cold water and hot water in proportion to generate warm water at the set temperature.

[0072] Specifically, since the ultraviolet-visible spectral band of sweat stains at the set temperature of warm water can be obtained through experiments, the set temperature is preferably 37 degrees Celsius, and the ultraviolet-visible spectral band of sweat stains is more stable.

[0073] Therefore, after the user's exercise ends, the clothes can be washed with warm water immediately, ensuring the accuracy of the stain index including the amount of sweat stains detected.

[0074] In this embodiment, the specific process of the method for feeding back the exercise intensity based on the washing device is as follows: before the user's exercise ends, the user inputs a reservation instruction for the expected exercise end time point through the washing device or the mobile device, and can modify the expected exercise end time point through the washing device or the mobile device;

[0075] According to the reservation instruction including the expected exercise end time point and the heating duration required to heat the washing water to the set temperature, the washing device performs the heating work of the washing water, and then keeps the washing water at the set temperature until the user uses it;

[0076] After the user finishes exercising, the clothes with wet sweat stains are put into the washing device. The washing device washes the clothes without adding laundry agents with warm water at the set temperature. During the washing process, multiple stain indexes including the amount of sweat stains in the washing water are detected and analyzed to obtain a relatively accurate stain index;

[0077] After determining the stain index range into which the stain index falls, determine the exercise intensity corresponding to the stain index range. For example, set the first limit value to 9. If the stain index is less than or equal to 9, it is determined as the low stain index range, and the low stain index range corresponds to a smaller exercise intensity level. At this time, the exercise situation information of the user obtained from the mobile device can be combined for comprehensive judgment, and a more accurate exercise intensity and advice information can be obtained, and the exercise intensity and advice information are pushed and fed back to the user through the mobile device, or voice broadcast;

[0078] Set the second limit value to 14. If the stain index is greater than 9 and less than or equal to 14, it is determined as the medium stain index range, and the medium stain index range corresponds to a medium exercise intensity level. At this time, the exercise situation information of the user obtained from the mobile device can also be combined for comprehensive judgment, and a more accurate exercise intensity and advice information can be obtained, and the exercise intensity and advice information are pushed and fed back to the user through the mobile device, or voice broadcast;

[0079] If the stain index is greater than 14, it is determined as the high stain index range, and the high stain index range corresponds to a larger exercise intensity level. At this time, the exercise situation information of the user obtained from the mobile device can also be combined for comprehensive judgment, and a more accurate exercise intensity and advice information can be obtained, and the exercise intensity and advice information are pushed and fed back to the user through the mobile device, or voice broadcast.

[0080] Furthermore, based on the exercise intensity and exercise condition information, more targeted advice information can be obtained, such as "It is recommended to reduce the amount of exercise next time" and "It is recommended to supplement salt reasonably".

[0081] In this embodiment, since sweat stains are easily soluble in warm water, during the washing process with warm water without adding laundry treatment agents, the stain index including the amount of sweat stains is detected. This stain index can objectively reflect the state of the human body after exercise, and then feedback a more objective and accurate exercise intensity to the user, helping to perform exercise at an appropriate intensity next time. Performing exercise at an appropriate intensity next time is beneficial to the user's healthy life. After the user's exercise ends, the clothes can be immediately washed with warm water, ensuring the accuracy of the stain index including the amount of sweat stains detected.

[0082] Embodiment 2

[0083] As Figure 1 and 2 shown, this embodiment provides a washing equipment system for feedback of exercise intensity. The washing equipment system is used to execute the method for feedback of exercise intensity based on a washing equipment as described in Embodiment 1. The washing equipment system includes: a washing module for washing without adding laundry treatment agents with warm water; an optical detection module for detecting the stain index in the washing module; a processing module communicatively connected to the optical detection module for receiving and outputting the stain index of the optical detection module; a feedback module communicatively connected to the processing module for receiving the exercise intensity of the processing module and outputting the information of the exercise intensity; wherein the stain index includes the amount of sweat stains.

[0084] The washing module at least includes a washing tub, a motor for controlling the rotation of the washing tub, and a heating device for washing water.

[0085] The optical detection module includes an optical sensor such as a near-infrared spectroscopy sensor or an ultraviolet spectroscopy sensor that can detect the stain index in water.

[0086] Specifically, the stain index is a feedback variable obtained by detecting with optical sensor modules such as a near-infrared spectrum sensor and an ultraviolet spectrum sensor, preferably obtained through the ultraviolet spectrum sensor module. Further, the ultraviolet spectrum sensor uses ultraviolet absorption spectroscopy for stain index detection. Ultraviolet absorption spectroscopy detects the stain index through the corresponding relationship between a substance and its ultraviolet-visible spectroscopy (UV-VIS) when the substance absorbs light of a specific wavelength to reach the maximum value. The electromagnetic wave wavelength corresponding to the ultraviolet spectrum sensor is shorter and has greater energy, capable of penetrating tiny bubbles and having a better response to micron-sized particles. The stain index includes various substances that cannot be detected by conventional sensors. The conventional sensors such as infrared pair tube sensors cannot detect organic soluble stains, including oily stains, proteins, fabric softeners, and emulsions, etc. While the ultraviolet spectrum sensor can detect the above-mentioned organic soluble stains, it can also detect insoluble particulate matter. Among them, the protein in the organic soluble stains includes sweat stains. Therefore, while having a larger detection range, the ultraviolet spectrum sensor can better detect the stain index including the amount of sweat stains in warm water without fabric softener.

[0087] Further, the band of the sweat stain in the ultraviolet-visible spectrum is compared and analyzed with the spectral band of the detected stain index in the ultraviolet-visible spectrum, so as to obtain a more accurate stain index of the amount of sweat stains.

[0088] Further, a water temperature detection module is provided in the washing tub of the washing device. The water temperature detection module is communicatively connected to the processing module. The water temperature detection module is used to detect the water temperature of the warm water in the washing tub when the optical detection module detects the stain index including the amount of sweat stains, generating the water temperature. The processing module receives the water temperature and controls the water temperature of the water inlet into the washing tub by the washing module according to the water temperature, so that the warm water in the washing tub is maintained at a set temperature. The set temperature is preferably 37 degrees Celsius, making the band of the ultraviolet-visible spectrum of the sweat stain more stable.

[0089] In this embodiment, the processing module is used to receive the stain index of the optical detection module and generate the exercise intensity according to the stain index.

[0090] The processing module includes a central processing unit (CPU), a general-purpose processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), etc. The general-purpose processor can be a microprocessor or any conventional processor, etc. The logical judgment executed by the processing module can be completed by a hardware processor, or by a combination of hardware and software modules in the processor.

[0091] In this embodiment, the communication connection can also be an electrical coupling or a direct coupling between modules. The communication connection can be a wired communication, such as serial communication, or a wireless communication, such as Bluetooth, WIFI (Wireless Fidelity) network, infrared communication, etc.

[0092] In this embodiment, the storage module is used to store data including the stain index range and the exercise intensity; the processing module is used to judge the stain index range into which the stain index falls and generate an exercise intensity corresponding to the stain index range.

[0093] As a specific implementation manner, when the storage module is a read-only memory (ROM) or a random access memory (RAM), it can be built into the central processing unit, general-purpose processor or digital signal processor of the processing module.

[0094] As another specific implementation manner, the storage module is applied to an external storage unit expanded by the processing module, and the storage module and the processing module can interact or communicate.

[0095] In this embodiment, the processing module is further used to, when no clothes are placed in the washing module, receive the stain index collected by the optical detection module, store multiple stain indexes as historical data in the storage module, establish a stain index reference value according to the historical data, and correct the stain index collected by the optical detection module received when clothes are placed in the washing module according to the stain index reference value.

[0096] The influence of the stain index of the tap water used by the washing equipment on the detection result is eliminated.

[0097] In this embodiment, a reservation module is communicatively connected to a processing module and is configured to receive a reservation instruction input by a user. The processing module is communicatively connected to the reservation module and a washing module respectively, and is configured to receive the reservation instruction from the reservation module and generate a time point at which the washing device generates warm water according to the reservation instruction. The washing module is configured to receive the time point and generate warm water for washing without adding laundry treatment agents at the corresponding time point.

[0098] Enable the system to implement the method based on the feedback of the exercise intensity of the washing device.

[0099] In this embodiment, the feedback module includes a washing device and / or a mobile terminal, and the feedback module is configured to output information on the exercise intensity through the washing device and / or the mobile terminal.

[0100] It is realized that through the washing device and / or the mobile device, the information on the exercise intensity can be better output to the user.

[0101] When the feedback module includes the control panel of the washing device, the information can be output through the screen of the control panel.

[0102] In this embodiment, the mobile device is specifically an intelligent device with communication functions, such as a smart phone, a smart bracelet, a smart voice speaker, a smart remote control screen, etc. When the feedback module includes a mobile device, the mobile device pushes feedback to the user or broadcasts voice to output information.

[0103] As a specific implementation manner, the processing module is applied to the processor of a smart phone and the controller of a washing device, and the processor and the controller are communicatively connected through WIFI or Bluetooth, so as to implement the method described in the first embodiment at a lower cost.

[0104] In this embodiment, a washing device system including a washing device and a mobile device realizes that since sweat stains are easily soluble in warm water, during the washing process without adding laundry treatment agents with warm water, a stain index including the amount of sweat stains is detected, and the amount of sweat stains discharged by the human body during exercise is reflected through the stain index, so that the stain index can objectively reflect the state of the human body after exercise, feedback a more objective and accurate exercise intensity to the user, help to perform appropriate-intensity exercise next time, and is beneficial to the healthy life of the user; it is realized that after the user's exercise ends, the clothes can be immediately washed with warm water, ensuring the accuracy of the detected stain index including the amount of sweat stains.
