[0044] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Reference Figure 1, showing a step flow chart of a control method based on a water softening device in a washing machine provided by some embodiments of the present invention, wherein the water softening device is provided with a accommodating chamber, a resin loading chamber and an ion detector are provided in the accommodating chamber, and the resin loading chamber is loaded with resin.

[0046] like Figure 2 A structural schematic diagram of a water softening device in a washing machine is provided for some embodiments of the present invention, wherein the softened water loading may include a detergent box 1, a water box 2, a water inlet 3, an upper cavity 4, a resin loading cavity cover 5, an upper drain port 6, an intermediate connecting portion 7, a resin loading cavity 8, a gasket 9, a lower cavity 10, an ion detector mounting box 11, and a lower drain port 12.

[0047] Among them, the upper cavity 4, the resin loading cavity cover 5, the middle connecting part 7, the resin loading cavity 8, the gasket 9, the lower cavity 10, and the ion detector installation box 11 can form an accommodating cavity.

[0048] An ion detector can be installed in the ion detector mounting box 11 to detect water quality. The resin loading chamber 8 is loaded with resin, which can be used to soften water and remove minerals (such as calcium and magnesium) in water to protect the internal components of the washing machine from the influence of hard water, improve the washing effect, and extend the service life of the washing machine.

[0049] As some examples, the water softening device is located between the outer barrel of the washing machine and the water inlet device, and is fixed to the outer barrel of the washing machine by a clamp. During the washing process, the slight vibration frequency of the movement of the washing machine itself can drive the water vibration inside the water softening device to accelerate the irregular movement of molecules and increase the exchange rate of ions inside the water softening device.

[0050] In some embodiments of the present invention, the softening water device is provided with a water inlet 3, an upper drain port 6, and a lower drain port 12 connected to the accommodating chamber; the water inlet 3 is connected to the water inlet device of the washing machine, the upper drain port 3 is connected to the outer tub of the washing machine, and the lower drain port 12 is connected to the drain device of the washing machine. When the softening water device recovers the ability to regenerate resin, waste water is discharged, and the accumulated liquid in the softening water device is discharged to the flushing water pipe after washing, so as to prevent the drainage device from accumulating dirt and breeding bacteria.

[0051] In some embodiments of the present invention, the ion detector is disposed at one end of the cavity of the accommodating cavity close to the lower drain outlet 12 .

[0052] In some embodiments of the present invention, the water softening device is provided with an upper shell portion, a lower shell portion, and an intermediate connecting portion 7 connecting the upper shell portion and the lower shell portion, the upper cavity 4 is arranged in the upper shell portion, and the lower cavity 10 is arranged in the lower shell portion and the intermediate connecting portion 7.

[0053] The softening water device comprises an upper shell, a lower shell, and an intermediate connecting part 7 connecting the upper shell and the lower shell. The upper shell and the intermediate connecting part are connected to form an upper cavity 4, and the lower shell and the intermediate connecting part are connected to form a lower cavity 10.

[0054] In some embodiments of the present invention, the water inlet 3 is arranged on the upper shell portion, the upper drain outlet 6 is arranged on the middle connecting portion, and the lower drain outlet 12 is arranged on the lower shell portion.

[0055] In some embodiments of the present invention, the intermediate connection portion 7 is connected to the upper shell portion and the lower shell portion via a gasket.

[0056] In some examples, the upper shell portion can be connected to the middle connecting portion 7 via a gasket to form an upper cavity 4; the lower shell portion can be connected to the middle connecting portion 7 via a gasket to form a lower cavity 10, and the connecting portion is sealed by a gasket to prevent liquid from overflowing.

[0057] In some embodiments of the present invention, the intermediate connection portion 7 is connected to the cavity body of the resin loading cavity via threads.

[0058] In some embodiments of the present invention, the accommodating chamber includes an upper chamber 4 and a lower chamber 10, and the upper chamber 4 and the lower chamber 10 are isolated from each other; the resin loading chamber has a cover (resin loading chamber cover 5) and a loading chamber, the cover 5 is located in the upper chamber 4, the loading chamber is located in the lower chamber 10, and the cover 5 and the loading chamber are provided with through holes. The through holes with a diameter smaller than the resin particle size provided in the cover and the loading chamber can facilitate water to fully react with the regenerated resin in the resin loading chamber.

[0059] Specifically, the following steps may be included:

[0060] Step 101, in response to the start of a washing program, water is introduced into the accommodating cavity.

[0061] In practical applications, a washing program refers to a series of operations preset in a smart home device (such as a washing machine) for cleaning clothes.

[0062] The accommodating chamber refers to the chamber used to store and treat water in the softening water device, such as Figure 2 The accommodating chamber can be composed of an upper cavity 4, a resin loading cavity cover 5, an intermediate connecting portion 7, a resin loading cavity 8, a gasket 9, a lower cavity 10, and an ion detector mounting box 11.

[0063] As some examples, after the washing program is started, the washing machine can control the water inlet valve to open, allowing water to flow into the accommodating chamber through the water inlet device with the detergent in the detergent box to soften the water.

[0064] In some embodiments of the present invention, in response to starting a washing program, supplying water into the accommodating chamber comprises: in response to starting a washing program, closing the lower drain outlet and opening the upper drain outlet, and supplying water into the accommodating chamber through the water inlet.

[0065] like Figure 2 After the washing program is started, the smart home device will first close the lower drain port 12 of the softening water device to prevent the water from flowing out of the accommodating chamber during the water inlet stage; at the same time, the smart home device will open the upper drain port 6 to allow air to escape during the water inlet stage to help the water flow into the accommodating chamber more smoothly; then, the water inlet valve is controlled to open, allowing water to flow into the accommodating chamber through the water inlet 3 of the softening water device to soften the water.

[0066] Step 102: Detect the ion content of the water in the accommodating chamber by using the ion detector.

[0067] Among them, an ion detector is an instrument that can measure the ion concentration in water. It can use electrochemical principles or optical principles to detect the ion content in water. The ion content refers to the total amount of ions contained in water or the concentration of specific ions, such as calcium and magnesium ions.

[0068] like Figure 2 After the washing program starts and water enters the accommodating chamber, the water in the accommodating chamber can be detected by the ion detector in the ion detector installation box 11 at the bottom of the accommodating chamber to obtain specific information on the ion content in the water.

[0069] As some examples, when the content of metal ions such as calcium and magnesium in the water in the accommodating chamber is low, the washing machine will normally take in water and run the washing program. After the dehydration is completed, the second water outlet pipe of the softening water device will be opened for S (such as 10 minutes) minutes, and the operation will end after the washing machine drainage device is flushed.

[0070] Step 103: When the ion content is greater than a preset content, a message is fed back to remind the user to add salt.

[0071] Among them, the preset content refers to the standard value of the ion content that is preset or specified in advance. The preset content can be determined based on actual application requirements, water quality standards and other factors. For example, the preset content can be 0-100 mg / L; when the actual measured ion content exceeds this standard, it means that the water needs to be softened.

[0072] After detecting that the ion content of the water in the accommodating chamber is greater than the preset content, the user can be reminded that the ion content in the current water has exceeded the preset standard, and the user is advised to adjust or improve it by adding salt to the water softening device.

[0073] Among them, adding salt can increase the concentration of certain ions in the water (such as sodium chloride). The sodium ions in the brine are the key to regenerating the resin. They can replace the calcium and magnesium ions on the resin and restore the resin to its initial state. The brine can not only provide enough sodium ions to regenerate the resin, but also help remove impurities in the resin loading chamber, reduce pollution, and ensure that the exchange capacity of the resin is maximized.

[0074] As some examples, when the ion detector under the accommodating cavity shows that the content of calcium and magnesium ions is too high (when the ion content is greater than a preset content), the washing machine can sound an alarm to remind the user to add salt, and at the same time the first water outlet pipe of the water softening device is closed.

[0075] In some embodiments of the present invention, when the ion content is greater than a preset content, after feeding back a message to remind the user to add salt, it also includes: when it is detected that the salt addition is completed, executing the ion content of the water in the accommodating chamber by the ion detector again; when the salt addition is not detected to be completed, discharging the water in the accommodating chamber into the outer barrel of the washing machine.

[0076] After the feedback message reminding the user to add salt is received, the user can add salt to the water inlet device and turn off the alarm. When the washing machine detects that the salt adding is completed, it can open the water inlet valve, and close the water inlet valve of the washing machine after letting in water for N minutes (such as 5 minutes) to mix the salt added by the user with the water, and let the mixed salt water stand in the accommodating chamber for M minutes (such as 5 minutes) to allow the resin in the resin loading chamber in the accommodating chamber to fully contact the salt water and react.

[0077] If, after the user is fed back a message reminding him to add salt, the alarm continues to sound but the user does not add salt (i.e., when the completion of salt addition is not detected), the washing machine can automatically perform a normal washing program after N minutes (e.g., 3 minutes), and discharge the water in the accommodating cavity into the outer barrel of the washing machine through the first water outlet.

[0078] In some embodiments of the present invention, when the ion content is greater than a preset content, feedback is provided to remind the user to add salt, including: when the ion content is greater than a preset content, feedback is provided to remind the user to add salt, and the upper drain outlet is closed.

[0079] In actual applications, when the ion content is greater than the preset content, after feedback is given to remind the user to add salt, the washing machine can close the upper drain port to prevent hard water from entering the outer barrel of the washing machine.

[0080] In some embodiments of the present invention, when it is detected that the salt addition is completed, the step of detecting the ion content of the water in the accommodating chamber by the ion detector is performed again, including: when it is detected that the salt addition is completed, water is introduced into the accommodating chamber through the water inlet so that the water in the accommodating chamber covers the resin loading chamber; after standing for a preset period of time, the lower drain port is opened to discharge the water in the accommodating chamber; water is introduced into the accommodating chamber through the water inlet so that the water in the accommodating chamber covers the resin loading chamber, and the step of detecting the ion content of the water in the accommodating chamber by the ion detector is performed again.

[0081] In some examples, the preset time length can be determined based on the ion content in the water. If the ion content is greater than or equal to 250 mg / L, the preset time length can be 10 minutes. If the ion content is greater than or equal to 100 mg / L and less than or equal to 150 mg / L, the preset time length can be 5 minutes. Technical personnel in this field can adjust it according to actual conditions.

[0082] After the feedback message reminding the user to add salt is sent, the user can add salt to the water inlet device and turn off the alarm. When the washing machine detects that the salt adding is completed, it can open the water inlet valve, and let water into the accommodating chamber through the water inlet device and the water inlet for N minutes (such as 5 minutes), and then close the water inlet valve of the washing machine to allow the water in the accommodating chamber to cover the resin loading chamber, and allow the salt added by the user to mix with the water; and allow the mixed salt water to stand in the accommodating chamber for M minutes (such as 5 minutes) to allow the resin in the resin loading chamber and the salt water in the accommodating chamber to fully contact and react.

[0083] After the standing time reaches the preset time, the washing machine can open the lower drain outlet and drain the water for D minutes (such as 2 minutes); after the water containing a large amount of calcium and magnesium ions is discharged from the accommodating chamber, the washing machine can close the lower drain outlet, open the water inlet valve again, and let water into the accommodating chamber through the water inlet device and the water inlet for N minutes (such as 2 minutes), then close the washing machine water inlet valve and use the ion detector again to detect the ion content of the water in the accommodating chamber.

[0084] Step 103, when the ion content is less than or equal to a preset content, the water in the accommodating cavity is discharged into the outer barrel of the washing machine.

[0085] In actual application, if the ion detector detects that the ion content of the water in the accommodating cavity is less than or equal to the preset content, the washing machine can open the upper drain port to discharge the water in the accommodating cavity through the upper drain port to the outer barrel of the washing machine for washing.

[0086] In an embodiment of the present invention, water is introduced into the accommodating chamber in response to the start of a washing program; the ion content of the water in the accommodating chamber is detected by an ion detector; when the ion content is greater than a preset content, a message is fed back to remind the user to add salt; when the ion content is less than or equal to the preset content, the water in the accommodating chamber is discharged into the outer barrel of the washing machine, thereby realizing the detection of water quality by the ion detector in the washing machine, and then providing the washing machine with water with lower hardness, so as to protect clothes, improve washing effects and increase the service life of the washing machine.

[0087] The following is combined with Figure 3 The present invention is further described:

[0088] Step 301, start the washing program.

[0089] Step 302: the lower drain outlet of the softening water device is closed and the upper drain outlet is opened.

[0090] Step 303, water enters the softening water device, and the ion detector detects whether the ion concentration (ion content) exceeds the standard. If yes, proceed to step 304, otherwise proceed to step 312.

[0091] Step 304, start the alarm to remind the user to add salt, and close the drain outlet of the softening water device.

[0092] Step 305 , determining whether the user adds salt and closes the alarm button, if yes, proceeding to step 306 ; if the user does not respond, opening the upper drain port of the softening water device, and proceeding to step 312 .

[0093] Step 306, open the water inlet valve to let water in for N minutes.

[0094] Step 307, close the water inlet valve, and let the tap water stand in the softening water device for M minutes.

[0095] Step 308, open the lower drain outlet of the softening water device for S minutes, and then close the lower drain outlet.

[0096] Step 309, open the water inlet valve for N minutes.

[0097] Step 310 , the ion detector detects whether the ions exceed the standard, if yes, proceed to step 308 , otherwise proceed to step 311 .

[0098] Step 311, close the lower drain outlet of the softening water device and open the upper drain outlet.

[0099] Step 312, start the washing program.

[0100] Step 313: After the dehydration is completed, the lower drain outlet of the softening water device is opened for S minutes.

[0124] like Figure 2 After the washing program starts and water enters the accommodating chamber, the water in the accommodating chamber can be detected by the ion detector in the ion detector installation box 11 at the bottom of the accommodating chamber to obtain specific information on the ion content in the water.

[0125] As some examples, when the content of metal ions such as calcium and magnesium in the water in the accommodating chamber is low, the washing machine will normally take in water and run the washing program. After the dehydration is completed, the second water outlet pipe of the softening water device will be opened for S (such as 10 minutes) minutes, and the operation will end after the washing machine drainage device is flushed.

[0126] Step 403: When the ion content is greater than a preset content, a message is fed back to remind the user to add salt.

[0127] Among them, the preset content refers to the standard value of the ion content that is preset or specified in advance. The preset content can be determined based on actual application requirements, water quality standards and other factors. For example, the preset content can be 0-100 mg / L; when the actual measured ion content exceeds this standard, it means that the water needs to be softened.

[0128] After detecting that the ion content of the water in the accommodating chamber is greater than the preset content, the user can be reminded that the ion content in the current water has exceeded the preset standard, and the user is advised to adjust or improve it by adding salt to the water softening device.

[0129] Among them, adding salt can increase the concentration of certain ions in the water (such as sodium chloride). The sodium ions in the brine are the key to regenerating the resin. They can replace the calcium and magnesium ions on the resin and restore the resin to its initial state. The brine can not only provide enough sodium ions to regenerate the resin, but also help remove impurities in the resin loading chamber, reduce pollution, and ensure that the exchange capacity of the resin is maximized.

[0130] As some examples, when the ion detector under the accommodating cavity shows that the content of calcium and magnesium ions is too high (when the ion content is greater than a preset content), the washing machine can sound an alarm to remind the user to add salt, and at the same time the first water outlet pipe of the water softening device is closed.

[0131] Step 404, when it is detected that the salt addition is completed, the ion content of the water in the accommodating chamber is detected by the ion detector again; when the salt addition is not detected to be completed, the water in the accommodating chamber is discharged into the outer drum of the washing machine.

[0132] After the feedback message reminding the user to add salt is received, the user can add salt to the water inlet device and turn off the alarm. When the washing machine detects that the salt adding is completed, it can open the water inlet valve, and close the water inlet valve of the washing machine after letting in water for N minutes (such as 5 minutes) to mix the salt added by the user with the water, and let the mixed salt water stand in the accommodating chamber for M minutes (such as 5 minutes) to allow the resin in the resin loading chamber in the accommodating chamber to fully contact the salt water and react.

[0133] If, after the user is fed back a message reminding him to add salt, the alarm continues to sound but the user does not add salt (i.e., when the completion of salt addition is not detected), the washing machine can automatically perform a normal washing program after N minutes (e.g., 3 minutes), and discharge the water in the accommodating cavity into the outer barrel of the washing machine through the first water outlet.

[0134] In some embodiments of the present invention, when the ion content is greater than a preset content, feedback is provided to remind the user to add salt, including: when the ion content is greater than a preset content, feedback is provided to remind the user to add salt, and the upper drain outlet is closed.

[0135] In actual applications, when the ion content is greater than the preset content, after feedback is given to remind the user to add salt, the washing machine can close the upper drain port to prevent hard water from entering the outer barrel of the washing machine.

[0136] In some embodiments of the present invention, when it is detected that the salt addition is completed, the step of detecting the ion content of the water in the accommodating chamber by the ion detector is performed again, including: when it is detected that the salt addition is completed, water is introduced into the accommodating chamber through the water inlet so that the water in the accommodating chamber covers the resin loading chamber; after standing for a preset period of time, the lower drain port is opened to discharge the water in the accommodating chamber; water is introduced into the accommodating chamber through the water inlet so that the water in the accommodating chamber covers the resin loading chamber, and the step of detecting the ion content of the water in the accommodating chamber by the ion detector is performed again.

[0137] In some examples, the preset time length can be determined based on the ion content in the water. If the ion content is greater than or equal to 250 mg / L, the preset time length can be 10 minutes. If the ion content is greater than or equal to 100 mg / L and less than or equal to 150 mg / L, the preset time length can be 5 minutes. Technical personnel in this field can adjust it according to actual conditions.

[0138] After the feedback message reminding the user to add salt is sent, the user can add salt to the water inlet device and turn off the alarm. When the washing machine detects that the salt adding is completed, it can open the water inlet valve, and let water into the accommodating chamber through the water inlet device and the water inlet for N minutes (such as 5 minutes), and then close the water inlet valve of the washing machine to allow the water in the accommodating chamber to cover the resin loading chamber, and allow the salt added by the user to mix with the water; and allow the mixed salt water to stand in the accommodating chamber for M minutes (such as 5 minutes) to allow the resin in the resin loading chamber and the salt water in the accommodating chamber to fully contact and react.

[0139] After the standing time reaches the preset time, the washing machine can open the lower drain outlet and drain the water for D minutes (such as 2 minutes); after the water containing a large amount of calcium and magnesium ions is discharged from the accommodating chamber, the washing machine can close the lower drain outlet, open the water inlet valve again, and let water into the accommodating chamber through the water inlet device and the water inlet for N minutes (such as 2 minutes), then close the washing machine water inlet valve and use the ion detector again to detect the ion content of the water in the accommodating chamber.

[0140] Step 405, when the ion content is less than or equal to a preset content, the water in the accommodating cavity is discharged into the outer barrel of the washing machine.

[0141] In actual application, if the ion detector detects that the ion content of the water in the accommodating cavity is less than or equal to the preset content, the washing machine can open the upper drain port to discharge the water in the accommodating cavity through the upper drain port to the outer barrel of the washing machine for washing.

[0142] In an embodiment of the present invention, water is introduced into the accommodating chamber in response to the start of a washing program; the ion content of the water in the accommodating chamber is detected by an ion detector; when the ion content is greater than a preset content, a message is fed back to remind the user to add salt; when it is detected that the salt addition is completed, the ion content of the water in the accommodating chamber is detected again by the ion detector; when the salt addition is not detected to be completed, the water in the accommodating chamber is discharged into the outer barrel of the washing machine; when the ion content is less than or equal to the preset content, the water in the accommodating chamber is discharged into the outer barrel of the washing machine; when the ion content is less than or equal to the preset content, the water in the accommodating chamber is discharged into the outer barrel of the washing machine, thereby realizing the detection of the ion content by the ion detector of the water softening device in the washing machine, and reminding the user to add salt when the ion content is high, and then providing the washing machine with water with lower hardness through the water softening device, so as to protect the clothes, improve the washing effect and increase the service life of the washing machine.
