DETAILED DESCRIPTION

[0042] Next, the present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be understood that the terms "having," "including," and "comprising" used herein do not imply the presence or addition of one or more other elements or combinations thereof.

[0043] Example 1

[0044] The present invention relates to a method for automatically detecting the residual amount of a washing solvent, comprising the following steps: Figure 1 As shown:

[0045] S101: Acquire a first voltage value of a washing solvent in a washing box collected by an electrode in a current program;

[0046] S102: Determine whether the first voltage value is greater than a lower threshold;

[0047] In some embodiments, the AD value of the partial pressure of a customized detergent when the electrode just contacts the detergent liquid surface is 1850±50; in this case, the lower threshold is set to 1800, and S102 indicates determining whether the first voltage value exceeds 1800. It should be understood that the lower threshold may also be other values, which can be determined specifically based on the customized detergent.

[0048] S103: If the first voltage value is less than the lower threshold, obtain a second voltage value of the detergent in the washing box collected by the electrode in the previous washing process, and determine whether the second voltage value is greater than the lower threshold;

[0049] S104: If the second voltage value is greater than the lower threshold, a liquid shortage information is fed back. The remaining amount detection method of the present invention can intelligently identify the remaining amount of detergent in the washing box, thereby avoiding the phenomenon of insufficient detergent causing the clothes to be not washed clean.

[0050] It should be understood that the detergent automatically dispensed in the present invention is a customized detergent with a fixed conductivity. The detergent with a fixed conductivity is equivalent to a resistor, and the voltage division is fed back to the host computer, which obtains a digital value through AD conversion for judgment.

[0051] It should be understood that the wash solvents of the present invention are not mixed with water.

[0052] In some embodiments, when the first voltage value is greater than or equal to the lower limit threshold, although the current detergent is sufficient, it will still be used up; therefore, it is necessary to continuously monitor the number of washes to understand the remaining detergent in the washing box. Specifically, the steps include: Figure 2 As shown:

[0053] S201: If the first voltage value is greater than or equal to the lower threshold, obtaining the number of automatic injections of the washing solvent;

[0054] S202: If the number of automatic injections is less than the threshold number, sufficient washing solvent information is fed back.

[0055] It should be understood that the number threshold is related to the capacity of the washing box and the amount of detergent automatically added each time; in some embodiments, when the amount of detergent consumed each time is between 3-5 mL and the maximum amount of detergent that can be stored in the washing box is 100 mL, the number threshold is 30 times.

[0056] Specifically, when the number threshold is less than 30 times, the feedback is that the washing solvent is sufficient; when the number threshold is greater than or equal to 30 times, the feedback is that the liquid is insufficient. By executing S201-S202, the number of times the washing solvent can be automatically added to the washing box can be counted, so as to intelligently detect the remaining detergent in the washing box and improve the user experience.

[0057] If the second voltage value of the detergent in the washing box collected by the electrode in the previous washing process is less than 1800, it means that the washing solvent in the washing box at this time is not the washing solvent customized by our company. Therefore, it is necessary to observe the voltage value collected by the electrode in the next washing process to determine whether the washing solvent is in the process of disappearing from the presence. In some embodiments, the steps are further included, such as Figure 3 As shown:

[0058] S301: If the second voltage value is less than or equal to the lower threshold, obtaining a third voltage value of the detergent in the washing box collected by the electrode in the next washing process;

[0059] S302: Calculating a change in voltage during the next washing process based on the third voltage value and the second voltage value;

[0060] S303: If the voltage change is greater than the change threshold, a liquid shortage information is fed back.

[0061] If the voltage change is less than or equal to the change threshold, it is fed back that the washing solvent is sufficient.

[0062] It should be understood that the amount of washing solvent has little effect on the voltage value collected by the electrode. However, when the electrode is completely out of contact with the washing solvent, that is, when the washing solvent is exhausted, the voltage value collected by the electrode changes significantly. According to measurements, in some embodiments, the change threshold is 100. In step S303, if the voltage change is less than 100, it indicates that the electrode is still in contact with the washing solvent and there is sufficient washing solvent. When the change threshold is 100, if the voltage change is greater than or equal to 100, it indicates that the electrode is no longer in contact with the washing solvent, and feedback is provided indicating that the washing cartridge is low on liquid.

[0063] In some embodiments, the steps further include:

[0064] If the washing box is replaced or washing solvent is added to the washing box, the lower limit threshold and voltage value are initialized. The lower limit threshold is initialized to match the type and / or mixing method of the washing solvent under the current conditions; the voltage value is initialized (including the first voltage value and the second voltage value) to obtain a real-time and accurate voltage value. By performing the initialization operation, the accuracy of the remainder detection is improved.

[0065] It should be understood that if the washing box is replaced or washing solvent is added to the washing box, the initialized value also includes the program statistics, that is, the number of washes is recounted each time the wash is re-executed to ensure the accuracy of the washing number statistics and avoid misleading the clothing care device to make erroneous statistics, which affects the judgment of the remaining washing solvent.

[0066] The lower limit threshold is related to the type of washing solvent and the mixing mode of different washing solvents. In some embodiments, the method for obtaining the lower limit threshold further includes steps such as Figure 4 As shown:

[0067] S401: matching the type and / or mixing method of the washing solvent according to the first voltage value of the washing solvent in the washing box collected by the electrode in the current program;

[0068] S402: Matching a lower limit threshold corresponding to the current washing solvent according to the type and / or mixing mode of the washing solvent.

[0069] In some embodiments, the method for automatically detecting the remaining amount of washing solvent comprises the following steps: Figure 5 As shown:

[0070] S501: Acquire the first voltage value of the washing solvent in the washing box collected by clicking in the current program;

[0071] S502: Determine whether the first voltage value is greater than a lower threshold; if it is less than or equal to the lower threshold, proceed to S503.

[0072] S503: Obtain the second voltage value of the detergent in the washing box collected by the electrode in the last washing process, and determine whether the second voltage value is greater than the lower limit threshold; if it is less than or equal to the lower limit threshold, enter S504.

[0073] S504: Acquire a third voltage value of the detergent in the washing box collected by the electrode in the next washing process;

[0074] S505: Calculating a change in voltage value in the next washing process according to the third voltage value and the second voltage value;

[0075] S506: If the voltage change is greater than the change threshold, a liquid shortage message is fed back; if it is less than the change threshold, a sufficient washing solvent message is fed back.

[0076] In S502, if the first voltage value is greater than the lower limit threshold, the number of automatic injections of the washing solvent is obtained. If the number of automatic injections is less than the number threshold, sufficient washing solvent information is fed back; if it is greater than the number threshold, liquid shortage information is fed back.

[0077] In S503 , if the second voltage value is greater than the lower threshold, liquid shortage information is fed back.

[0078] Example 2

[0079] like Figure 6 As shown, a device 100 for automatically detecting the amount of a washing solvent is provided, comprising:

[0080] An acquisition unit 101 is configured to acquire a first voltage value of a washing solvent in a washing box collected by an electrode;

[0081] a determination unit 102 configured to determine whether the first voltage value is greater than a lower threshold;

[0082] The processing unit 103 is configured to obtain a second voltage value of the detergent in the washing box collected by the electrode in the last washing process if the first voltage value is less than the lower threshold, and feedback liquid shortage information if the second voltage value is still less than the lower threshold.

[0083] For detailed description of each of the above units, please refer to the corresponding description in the above method embodiment, which will not be repeated here.

[0084] Example 3

[0085] Combine Figure 7 As shown, a device 200 for automatically adding a residual amount of a washing solvent is presented in the form of a general computing device; including but not limited to: a memory 201, a processor 202; wherein,

[0086] The memory 201 stores program codes thereon; the processor 202 is connected to the memory and implements the clothing ironing method based on clothing identification in the first and second embodiments when the program codes are executed by the processor.

[0087] The remaining amount detection device 200 based on automatic addition of washing solvent may further include a bus connecting different system components (including the memory 201 and the processor 202 ).

[0088] Example 4

[0089] A clothing care device comprises a detergent box, a negative pressure generating device, and a residual amount detection device for automatically adding washing solvent as in the second and third embodiments.

[0090] In some embodiments, the remaining amount detection device is fixedly mounted on the washing box; in other embodiments, in order to facilitate the replacement of the washing box as a consumable material, an intermediate chamber is also included between the washing box and the negative pressure generating device, and the remaining amount detection device is fixedly mounted in the intermediate chamber.

[0091] Specifically, Figures 8 to 11 The clothing care device of the present invention includes a detergent box 10 , a detection device 20 and a negative pressure generating device 30 .

[0092] The detection device 20 includes a push rod 21 , a main body, a sealing member, a detection member 24 , a waterproof and breathable member 25 , a second sealing ring 26 and a liquid outlet pipe 27 .

[0093] The top rod 21 is hollow, forming a flow channel for the laundry treatment agent. The top rod 21 is attached to the main body via a seal that prevents leakage between the main body and the top rod 21. The top rod 21 is tilted to facilitate insertion of the detergent box 10 and allows it to be positioned on the front of the washing machine, creating an aesthetically pleasing and user-friendly design.

[0094] The main body is provided with a first mounting hole, a second mounting hole, a mounting surface 223, and an outer surface 224. The mounting surface 223 and the outer surface 224 are arranged opposite each other and are inclined. A liquid inlet cavity is formed between the mounting surface 223 and the outer surface 224. The conical shape of the liquid inlet cavity not only allows for insertion of the ejector pin 21, but also helps reduce the volume of the liquid inlet cavity, thus facilitating miniaturization of the washing machine.

[0095] The push rod 21 is mounted perpendicularly to the mounting surface 223. Since the mounting surface 223 is tilted, the push rod 21 is also tilted, facilitating insertion of the detergent box 10. Furthermore, the vertical mounting of the push rod 21 to the mounting surface 223 provides a more stable installation and more evenly distributes force during insertion, making it less likely to break. The main body also includes a detection chamber 226, which communicates with the liquid inlet chamber.

[0096] The detection member 24 is installed in the first installation hole and extends into the detection cavity 226. The detection member 24 detects the liquid level height of the detection cavity 226. When the clothes treatment agent in the detergent box 10 is exhausted, the liquid level height of the detection cavity 226 changes, and the detection member 24 alarms to remind the user to replenish the clothes treatment agent.

[0097] The waterproof breathable member 25 is mounted in the second mounting hole. External air enters the main body through the waterproof breathable member 25, compensating for internal air pressure and allowing the laundry treatment agent to flow from the detection chamber 226 into the inner drum. Specifically, the waterproof breathable member 25 is a waterproof breathable membrane. The waterproof breathable member 25 also includes several snap-fitting portions 250, with gaps formed between adjacent snap-fitting portions 250. The snap-fitting portions 250 are deformed by compression to extend into the second mounting hole, then recover within the second mounting hole, securing the waterproof breathable member 25 to the second mounting hole.

[0098] The second sealing ring 26 is installed between the waterproof breathable member 25 and the second mounting hole to seal the waterproof breathable member 25 and the second mounting hole to prevent leakage of the clothing treatment agent.

[0099] The liquid outlet pipe 27 extends from the main body and communicates with the detection chamber 226. The liquid outlet pipe 27 is connected to the negative pressure generating device 30, so that the clothes treating agent in the detection chamber 226 is pumped into the inner drum.

[0100] The negative pressure generating device 30 is a micro peristaltic pump. The outlet of the negative pressure generating device 30 is connected to a pipe of the washing machine's washing drum 80. While the negative pressure generating device 30 draws liquid from the detection device 20, it also pumps liquid into the washing machine's washing drum 80. The negative pressure generating device 30 is installed above the liquid level in the detection chamber 226 to prevent liquid in the detection chamber 226 from entering the negative pressure generating device 30. Using the negative pressure generating device 30 to dispense clothing treatment agent into the washing machine's washing drum 80 improves the accuracy of clothing treatment agent dispensing compared to manual dispensing, avoiding waste caused by excessive clothing treatment agent dispensing or poorly cleaned clothes caused by insufficient clothing treatment agent dispensing.

[0101] The negative pressure generating device 30 pumps the laundry treatment agent within the detection device 20 into the washing tub 80. During this process, the detection element 24 detects the liquid level in the detection chamber 226. When the laundry treatment agent within the detergent box 10 is depleted, the liquid level in the detection chamber 226 changes, and the detection element 24 sounds an alarm to remind the user to refill the laundry treatment agent. To refill the laundry treatment agent, the user simply removes the used detergent box 10 and inserts a new one. The laundry treatment agent in the detergent box 10 can be used for multiple washing cycles, eliminating the need to refill the washing machine with laundry treatment agent each time, reducing the number of steps, and making operation simple and convenient.

[0102] The detergent box 10 and the push rod 21 of the clothing care device of the present invention are plugged into each other so that the laundry treatment agent in the detergent box 10 flows into the liquid inlet chamber, and the negative pressure generating device 30 pumps the laundry treatment agent in the detection device 20 into the inner drum. When the laundry treatment agent in the detergent box 10 is exhausted, the detection device 20 alarms, eliminating the need for a laundry treatment agent dispensing structure and a flushing water channel, simplifying the structure and preventing the breeding of bacteria. When the laundry treatment agent in the detergent box 10 is exhausted, an alarm is automatically sounded to remind the user to add laundry treatment agent. In addition, the main body is provided with a mounting surface 223 and an outer surface 224. The mounting surface 223 and the outer surface 224 are inclined surfaces and are arranged opposite to each other. The mounting surface 223 and the outer surface 224 form a liquid inlet chamber, which is conducive to reducing the volume of the liquid inlet chamber and facilitating the miniaturization of the washing machine. The push rod 21 is perpendicularly mounted on the mounting surface 223. When the push rod 21 is tilted to facilitate plugging, the installation of the push rod 21 is more stable, the force on the push rod 21 is more uniform, and it is not easy to break.

[0103] The present application also relates to a washing machine, which comprises the above-mentioned clothing care device, a housing, a door 50, a frame 60, and a washing tub 80. The washing tub 80 is arranged obliquely in the washing machine.

[0104] The detergent box 10 is located below the door 50 and is plugged into the housing. The detergent box 10 is curved as a whole, so that when the detergent box 10 is plugged into the housing, the end surface of the detergent box 10 is integrated with the housing, which is beautiful and elegant. The plugging direction of the detergent box 10 is the same as the tilt direction of the washing tub 80.

[0105] The clothing care device is positioned entirely below the washing drum 80. The frame 60 is provided with a recess 70, which provides space for the device. This placement reduces the space occupied by the device within the washing machine, contributing to its miniaturization. During use, the clothing treatment agent first flows downward along the clothing care device under the influence of gravity, and is then pumped upward into the washing drum 80 by the negative pressure generating device 30.

[0106] Example 6

[0107] Through the description of the above embodiments, it is easy for those skilled in the art to understand that the example embodiments described here can be implemented by software or by combining software with necessary hardware. The technical solution according to the embodiments of the present application can be embodied in the form of a software product, which can be stored in a computer-readable storage medium (which can be a CD ROM, a USB flash drive, a mobile hard disk, etc.) or on a network, and includes a number of computer program instructions to enable a computing device (which can be a personal computer, a server, or a network device, etc.) to perform the above-mentioned method according to the embodiments of the present application.

[0108] The number of devices and processing scales described herein are intended to simplify the description of the present invention. Applications, modifications, and variations of the present invention will be readily apparent to those skilled in the art.

[0109] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.

[0110] The apparatus, electronic device, and non-volatile computer storage medium provided in the embodiments of this specification correspond to the method. Therefore, the apparatus, electronic device, and non-volatile computer storage medium also have similar beneficial technical effects as the corresponding method. Since the beneficial technical effects of the method have been described in detail above, the beneficial technical effects of the corresponding apparatus, electronic device, and non-volatile computer storage medium will not be repeated here.

[0111] In the 1990s, technological improvements could be clearly distinguished as either hardware improvements (for example, improvements to circuit structures like diodes, transistors, and switches) or software improvements (improvements to process flows). However, with the advancement of technology, many process flow improvements today can now be considered direct improvements to hardware circuit structures. Designers almost always create the corresponding hardware circuit structure by programming the improved process flow into the hardware circuit. Therefore, it cannot be said that a process flow improvement cannot be implemented using hardware modules. For example, a programmable logic device (PLD), such as a field programmable gate array (FPGA), is an integrated circuit whose logical function is determined by user programming. Designers can "integrate" a digital system on a PLD through their own programming, without having to hire a chip manufacturer to design and manufacture a dedicated integrated circuit chip. Moreover, nowadays, instead of manually fabricating integrated circuit chips, this programming is mostly done using "logic compiler" software. This is similar to the software compiler used when developing programs. Before compilation, the original code must also be written in a specific programming language, called a hardware description language (HDL). There is not just one HDL, but many, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc. The most commonly used ones are VHDL (Very-High-Speed ​​Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art will also understand that by simply programming the method flow in one of these hardware description languages ​​and then programming it into an integrated circuit, a hardware circuit that implements the logic method flow can be easily obtained.

[0112] The controller can be implemented in any suitable manner. For example, the controller can take the form of a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro)processor, logic gates, switches, application-specific integrated circuits (ASICs), programmable logic controllers, and embedded microcontrollers. Examples of controllers include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320. The memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art will also know that in addition to implementing the controller in a purely computer-readable program code format, the controller can be implemented in the form of logic gates, switches, application-specific integrated circuits, programmable logic controllers, and embedded microcontrollers by logically programming the method steps. Therefore, such a controller can be considered a hardware component, and the devices included therein for implementing various functions can also be considered as structures within the hardware component. Or even, the devices for implementing various functions can be considered as both software modules that implement the method and structures within the hardware component.

[0113] The systems, devices, modules, or units described in the above embodiments may be implemented by computer chips or entities, or by products having certain functions. A typical implementation device is a computer. Specifically, the computer may be, for example, a personal computer, a laptop computer, a cellular phone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.

[0114] For the convenience of description, the above devices are described as being divided into various units according to their functions. Of course, when implementing one or more embodiments of this specification, the functions of each unit can be implemented in the same or multiple software and / or hardware.

[0115] Those skilled in the art will appreciate that the embodiments of this specification may be provided as methods, systems, or computer program products. Therefore, the embodiments of this specification may take the form of a complete hardware embodiment, a complete software embodiment, or an embodiment combining software and hardware. Furthermore, the embodiments of this specification may take the form of a computer program product implemented on one or more computer-usable storage media (including but not limited to magnetic disk storage, CD-ROM, optical storage, etc.) containing computer-usable program code.

It should be understood that each process and / or box in the flowchart and / or block diagram, as well as the combination of processes and / or boxes in the flowchart and / or block diagram, can be implemented by computer program instructions.
