[0064] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0065] During the operation of a water softener, if the system powers off and then back on, the control program may become disrupted, potentially causing the water system of the multi-way valve in the softener to open, causing the water pressure within the multi-way valve to change and drop to zero voltage. The valve core in the softener is located on one side of the water inlet. As the valve core rises from zero pressure to operating pressure, water inertia impacts the valve core. This water hammer creates an imbalance between the pressure on one side of the valve core and the pressure on the other side, shifting the valve core's position. This results in the valve core being in a different position before the softener powers off than after it powers back on. The disruption in the softener's control program may be due to the memory chip lacking a power-failure memory module, or the memory chip having a power-failure memory module but the developer not enabling it.

[0066] like Figure 1 The figure shows a schematic diagram of a water hammer impact. After the water softener is powered on again, the control program of the water softener is disrupted, and the balance between the high and low water pressures in the multi-way valve body cannot be maintained. As a result, the valve core is in a different position before the water softener is powered off than after it is powered on again. The water softener may not be able to provide soft water to the user, which limits the use scenarios of the water softener and reduces the user experience of the water softener.

[0067] In view of this, the present application provides a method for controlling a soft water device. The method for controlling a soft water device provided in the embodiment of the present application can be applied to Figure 2 In the application environment shown, the water softening device 200 includes a controller 202, a valve core 204 disposed in a multi-way valve body, and a position detection element 206 for detecting the position of the valve core 204. The position detection element 206 is in communication with the controller.

[0068] Specifically, the work position detection element 206 can detect and output the work position signal corresponding to the work position of the valve core 204. The controller records the work position identifier corresponding to the work position signal, and when the soft water device is powered on, controls the valve core 204 to rotate to the target work position corresponding to the recorded work position identifier. In this way, it can be ensured that the work position of the valve core is the same before the soft water device is powered off and after it is powered on again, thereby ensuring the user's experience of the soft water device. At the same time, it also expands the usage scenarios of the soft water device and solves the problem that the soft water device cannot provide soft water to the user after it is powered on again.

[0069] In one embodiment, the water softening device further includes a transmission component for driving the valve core 204. The transmission component is provided with a station positioning member that rotates synchronously with the transmission component. The station positioning member is provided with a transmissive portion corresponding to each station position. During the transmission process of the transmission component, the station positioning member passes through a station detection position of a station detection element. The station detection element can output a station position signal when the transmissive portion passes through the station detection position. In some embodiments, the transmission component can include gears.

[0070] like Figure 3 , a schematic diagram of a water softening device is provided. The water softening device includes a valve core 302, a work position detection element 304, and a motor 306. The water softening device may also include a transmission component, which may include a first gear 308 and a second gear 310. The first gear 308 and the second gear 310 are meshed and driven. Specifically, after the water softening device is powered on again, the controller may control the motor 306 to start, causing the motor 306 to rotate the first gear 308. The rotation of the first gear 308 drives the rotation of the second gear 310, thereby rotating the valve core 302 to the target work position corresponding to the recorded work position identifier.

[0071] It is understandable that after the controller determines that the valve core 302 rotates to the target position, it can send a control instruction to the motor 306. The motor 306 controls the first gear 308 to stop rotating according to the control instruction, thereby controlling the valve core 302 to stop rotating by stopping the second gear 310 from rotating.

[0072] Among them, Figure 3 The water softening device may further include a movable valve disc 312 and a fixed valve disc 314. The movable valve disc 312 is fixed to the lower end of the valve core 302. The second gear 310 drives the valve core 302 to rotate, thereby causing the movable valve disc 312 to rotate synchronously. During the rotation process, the fixed valve disc 314 remains stationary, while the movable valve disc 312 rotates synchronously with the valve core 302.

[0073] In one embodiment, the transmission component may include a gear, and the station positioning member may include a rib provided on the outer ring of the gear, and an opening portion corresponding to each station position may be present on the rib, and the opening portion is the transmission portion. Figure 3 The transmission component may include a first gear 308 and a second gear 310 , and the workstation positioning member may include a rib arranged on the outer ring of the second gear 310 .

[0074] It should be noted that the work station detection element cannot detect the signal when it has not passed through the opening part, and the work station detection element can detect the signal when it passes through the opening part. The signal change detected by the work station detection element is a change from nothing to something. Therefore, when the work station detection element detects that the signal change is from nothing to something, it can be determined that the transmission component drives the valve core to rotate to each work station position.

[0075] In one embodiment, the water softening device further includes a transmission component that drives the valve core 204. The transmission component is provided with a station positioning member that rotates synchronously with the transmission component. The station positioning member includes a shielding member corresponding to each station position. During the transmission process of the transmission component, the station positioning member passes through the station detection position of the station detection element. The station detection element outputs a station position signal when the shielding member passes through the station detection position. The shielding member may have a strip structure or other structure, which is not limited in this embodiment.

[0076] It should be noted that the work station detection element can detect the signal when it has not passed through the blocking member, and cannot detect the signal when it has passed through the blocking member. The signal change detected by the work station detection element is a change from presence to absence. Therefore, when the work station detection element detects that the signal change is from presence to absence, it can be determined that the transmission component drives the valve core to rotate to each work station position.

[0077] Based on the above description of the workstation positioning member, the workstation detection element may include a first signal transmitter and receiver, which includes a first transmitter and a first receiver. The workstation detection position of the workstation detection element includes a signal path between the first transmitter and the first receiver. The first signal transmitter and receiver may be a photoelectric switch or other type of device capable of transmitting and receiving signals, and this embodiment is not limited thereto.

[0078] For example, the transmission component includes a gear, the station positioning member includes a rib provided on the outer ring of the gear, the rib has an opening portion corresponding to each station position, and the first signal transmitter and receiver includes a first transmitter and a first receiver. Figure 4 and Figure 5 As shown, a schematic diagram of the ribs of the outer ring of the gear passing through the first signal transmitter and receiver and a schematic diagram of the opening part on the ribs of the outer ring of the gear passing through the first signal transmitter and receiver are respectively provided.

[0079] It can be seen that in Figure 4 In the embodiment, when the ribs of the outer ring of the gear pass through the first transmitter and the first receiver, the ribs of the outer ring of the gear block the transmission of the signal, so the first receiver cannot receive the signal sent by the first transmitter. Figure 5 In the example, when the opening in the rib of the gear outer ring passes through the first transmitter and the first receiver, the first receiver can receive the signal sent by the first transmitter because the opening in the rib of the gear outer ring does not block signal transmission. Therefore, when the first signal transmitter and receiver detects a change in signal from no to present, it can be determined that the transmission component is driving the valve core to rotate to each working position.

[0080] In one embodiment, the transmission component is further provided with a reset positioning member that rotates synchronously with the transmission component, and the reset positioning member is provided with a transmissive portion corresponding to the reset position. During the transmission process of the transmission component, the work station detection element outputs a reset position signal when the reset positioning member passes through the reset detection position of the work station detection element. The reset position signal instructs the controller to reset the work station position identifier corresponding to the recorded work station position signal.

[0081] It can be understood that by setting the reset positioning member, the work station position identifier corresponding to the work station position signal recorded in the controller can be reset, so that after the identifier is re-recorded next time, the work station corresponding to the re-recorded identifier can be distinguished.

[0082] In one embodiment, the reset positioning member includes a rib provided on the inner ring of the gear, and an opening portion corresponding to the reset position is present on the rib, and the opening portion is the transmissive portion. Figure 3 The reset positioning member includes a rib arranged on the inner ring of the second gear 310.

[0083] Based on the above description regarding the reset positioning member, the work position detection element may include a second signal transmitter and receiver, the second signal transmitter and receiver including a second transmitter and a second receiver, and the reset detection position of the work position detection element includes a signal path between the second transmitter and the second receiver. The second signal transmitter and receiver may be a photoelectric switch or other type of device capable of transmitting and receiving signals, and is not limited in this embodiment.

[0084] Wherein, when the transmission component includes a gear, the reset positioning member includes a rib provided on the inner ring of the gear, and there is an opening portion corresponding to the reset position on the rib, the content of the reset position signal obtained by the second transmitter and the second receiver can be referred to Figure 4 or Figure 5 The content shown is adapted to the description and will not be repeated here.

[0085] In combination with the above content, it can be seen that in one embodiment, the transmission component is provided with a station positioning member and a reset positioning member that rotate synchronously with the transmission component. The transmission component may include a gear, and the station positioning member includes a rib provided on the outer ring of the gear, and there are openings corresponding to the positions of each station on the rib. The reset positioning member includes a rib provided on the inner ring of the gear, and there are openings corresponding to the reset position on the rib. Specifically, in combination with Figure 3 The work station positioning member includes a rib arranged on the outer ring of the second gear 310, and the reset positioning member includes a rib arranged on the second gear 310.

[0086] like Figure 6 As shown, a structural schematic diagram of a second gear 310 is provided. Among them, the second gear 310 includes a station positioning member 602 and a reset positioning member 604. The station positioning member 602 includes a rib arranged on the outer ring of the second gear 310, and there are opening parts corresponding to the positions of each station on the rib, and each opening part corresponds to a different working station. For example, the stations corresponding to each opening part include station No. 1 (water supply station), station No. 2 (backwash station), station No. 3 (jet station 1), station No. 4 (slow wash station), station No. 5 (jet station 2), station No. 6 (water replenishment station) and station No. 7 (forward wash station); wherein, the target station is one of the working stations.

[0087] In one embodiment, when controlling the rotating valve core to move to different positions, the position can be determined by the angle of the valve core rotation. For example, if the current position of the valve core is the water supply position, the angle of the valve core corresponding to the water supply position is 0 degrees. When the valve core is controlled to rotate at an angle of 45 degrees, the valve core can be rotated to the backwash position. If the current position of the valve core is the water supply position, when the valve core rotates at an angle of 67 degrees, the valve core can be rotated to the jet position 1. If the current position of the valve core is the water supply position, when the valve core rotates at an angle of 86 degrees, the valve core can be rotated to the slow wash position. If the current position of the valve core is the water supply position, when the valve core rotates at an angle of 101 degrees, the valve core can be rotated to the jet position 2. If the current position of the valve core is the water supply position, when the valve core rotates at an angle of 286 degrees, the valve core can be rotated to the water replenishment position. The current position of the valve core is the water supply position. When the valve core rotates at an angle of 313 degrees, the valve core can be rotated to the forward washing position.

[0088] In one embodiment, when the target position of the valve core is different, the flow direction of the water supply from the outside in the water softening device is also different. The flow direction of the water supply in the water softening device is related to the structure of the fixed valve plate and the movable valve plate arranged in the multi-way valve body.

[0089] like Figure 7 and Figure 8As shown in the figure, a schematic diagram of the structure of the fixed valve plate and the movable valve plate in a water softening device is provided. The water softening device includes a fixed valve plate and a movable valve plate arranged in a multi-way valve body and adopting end face rotating sealing. Figure 7 In the embodiment, the fixed valve plate includes the first hole to the ninth hole, and the first hole to the ninth hole are respectively represented by numbers 702 to 718. Figure 8 In the embodiment, the movable valve plate includes a water-crossing groove 802, a center hole 804 of the movable valve plate, a water inlet groove 806, and a center hole water guide groove 808. In some embodiments, the water-crossing groove can be a U-shaped water-crossing groove.

[0090] In one embodiment, the water softening device further includes a softening tank and a water outlet. The target station may be a water supply station, which softens externally supplied water to provide drinkable soft water to users. Specifically, the water supply path within the water softening device is: water supply, water inlet tank, first hole, softening tank, sixth hole, cross-water tank, fifth hole, and water outlet. Water exiting the water outlet with a hardness less than or equal to a preset value is considered soft water and suitable for drinking.

[0091] In some embodiments, if the hardness of water coming out of the water outlet is greater than the preset hardness value, the controller can control the valve core to rotate in sequence to the water replenishment position, jet position 1, jet position 2, backwash position, forward wash position and slow wash position to soften the water. In this way, when the valve core is rotated to the water supply position again, the hardness value of the water coming out of the water outlet can be less than or equal to the preset hardness value.

[0092] It can be understood that the hardness of the water coming out of the water outlet is greater than the preset hardness value. The possible reason is that more calcium and magnesium ions are adsorbed on the resin in the soft water tank. Since the sodium ions on the surface of the resin are continuously softened and exchanged with the calcium and magnesium ions in the water, they are continuously reduced or no longer available. The ability to exchange with the calcium and magnesium ions in the water supply is weakened or the purpose of softening the water cannot be achieved. Therefore, when the hardness of the water coming out of the water outlet is greater than the preset hardness value, the water replenishment station, jet station 1, jet station 2, backwash station, forward wash station, and slow wash station can be carried out in sequence, so that the calcium and magnesium ions adsorbed on the resin can be discharged through the wastewater outlet in the soft water equipment, and the sodium ions can be regenerated on the resin in the soft water tank. Then, when the valve core rotates to the water supply station, the calcium and magnesium ions in the water supply can be replaced by the sodium ions regenerated on the resin to achieve the purpose of softening the water quality.

[0093] In one embodiment, the water softening device may further include an ejector and a salt tank. The target station may be a water replenishment station, which is used to replenish the salt tank with water to obtain sodium ions from the salt tank. Specifically, the water replenishment path in the water softening device is: water supply, ninth hole, ejector, and salt tank.

[0094] In one embodiment, the water softening equipment may further include an ejector, a softening tank, and a wastewater outlet. The target station may be the ejector station 1, which is used to regenerate sodium ions from the resin in the softening tank. Specifically, the jet flow path of the water supply in the water softening equipment is: water supply, third hole, ejector, seventh hole, cross-water trough, sixth hole, softening tank, first hole, center hole water guide groove, center hole of the movable valve plate, and wastewater outlet. The high-concentration sodium ions in the salt water exchange with the calcium and magnesium ions on the resin in the softening tank, resulting in water with a high concentration of calcium and magnesium ions exiting the wastewater outlet.

[0095] In one embodiment, the water softening system may further include an ejector, a softening tank, and a wastewater outlet. The target station may be the second ejector station, which is used to further reduce the concentration of sodium ions exiting the first jet path. Specifically, the second jet path of the water supply in the water softening system is as follows: water supply, fourth hole, ejector, ninth hole, cross-water trough, sixth hole, softening tank, first hole, center hole water guide groove, center hole of the movable valve plate, and wastewater outlet. The water exiting the wastewater outlet has a higher concentration of calcium and magnesium ions.

[0096] In one embodiment, the water softening system may further include a softening tank and a wastewater outlet. The target workstation may be a backwash station, which displaces calcium and magnesium ions from the resin in the softening tank and loosens the resin. Specifically, the backwash path of the water supply in the water softening system is: water supply, second hole, softening tank, first hole, center hole water guide groove, center hole of the movable valve plate, and wastewater outlet. The water exiting the wastewater outlet is the water containing calcium and magnesium ions displaced from the resin in the softening tank.

[0097] In one embodiment, the water softening system may further include a softening tank and a wastewater outlet. The target station may be a forward wash station, which is used to restore the performance of the resin in the softening tank. Specifically, the forward wash path of the water supply in the water softening system is: water supply, first hole, softening tank, sixth hole, center hole water guide groove, center hole of the movable valve plate, and wastewater outlet. The water exiting the wastewater outlet is water containing calcium and magnesium ions displaced from the resin in the softening tank.

[0098] In one embodiment, the water softening equipment may further include a softening tank and a wastewater outlet. The target station may be a slow wash station, which is used to rinse salts from the resin using water. Specifically, the slow wash path of the water supply in the water softening equipment is: water supply, fifth hole, eighth hole, cross-water trough, sixth hole, softening tank, first hole, center hole water guide groove, center hole of the movable valve plate, and wastewater outlet. The water exiting the wastewater outlet is soft water with low concentrations of calcium and magnesium ions, which is rinsed from the resin in the softening tank.

[0099] It should be noted that when the valve core is in one of the following positions: backwash, jet 1, slow wash, jet 2, water replenishment, or forward wash, the corresponding position path can actually be a two-way water path, consisting of the water supply flow path when the valve core is in the corresponding position and the raw water supply path. For example, if the valve core is in the water supply position, the corresponding water supply path is: water supply, water inlet trough, first hole, soft water tank, sixth hole, cross-water trough, fifth hole, water outlet; the raw water supply path is: water supply, fifth hole, and water outlet. In this way, users can collect raw water from the water outlet for drinking, and this raw water is not soft water.

[0100] In conjunction with the above, in one embodiment, the workstation detection component 206 includes a first signal transmitter and receiver and a second signal transmitter and receiver. The first signal transmitter and receiver includes a first transmitter and a first receiver, and the workstation detection position of the workstation detection component includes a signal path between the first transmitter and the first receiver. The second signal transmitter and receiver includes a second transmitter and a second receiver, and the reset detection position of the workstation detection component includes a signal path between the second transmitter and the second receiver.

[0101] like Figure 9 As shown, a schematic structural diagram of a workstation detection element 206 is provided. The workstation detection element 206 includes a first signal transmitter and receiver 902 and a second signal transmitter and receiver 904. The first signal transmitter and receiver 902 includes a first transmitter and a first receiver, and the second signal transmitter and receiver 904 includes a second transmitter and a second receiver.

[0102] In one embodiment, the first signal transmitter and receiver 902 is configured to obtain a station position signal when an opening portion or a shielding member corresponding to each station position on the station positioning member passes through the signal path between the first transmitter and the first receiver, and transmit the station position signal corresponding to the station position of the valve core to the controller. Based on the station position signal corresponding to the station position of the valve core, the controller can determine the station position identifier corresponding to the station position signal and record the station position identifier. Thus, when the water softener is powered on, the controller can control the valve core to rotate to the target station corresponding to the recorded station position identifier.

[0103] In one embodiment, the second signal transmitter and receiver 904 is configured to receive a reset position signal when an opening portion or a blocking member corresponding to the reset position on the workstation positioning member passes through the signal path between the second transmitter and the second receiver, and transmit the reset position signal to the controller. This allows the controller to reset the recorded workstation position identifier based on the reset position signal, thereby preventing subsequent recorded workstation identifiers from being unable to determine the workstation position of the valve core.

[0104] In combination with the above, in one embodiment, Figure 10 As shown, a method for controlling a soft water device is provided, which is applied to Figure 2 The controller 202 in FIG. 1 is taken as an example to illustrate the process, which includes the following steps:

[0105] S1002: Acquire a work position signal corresponding to the work position of the valve core of the water softening equipment.

[0106] Among them, the working position signal refers to the signal generated when the valve core rotates to the working position. Figure 2 , the position detection element can detect and output the position signal corresponding to the position of the valve core.

[0107] In one embodiment, during the process of controlling the transmission component, a signal of a transmission portion corresponding to each station position on the station positioning member passing through a station detection element is obtained to obtain a station position signal.

[0108] Specifically, the workstation detection element includes a first signal transmitter and receiver, which can be a photoelectric switch. The first signal transmitter and receiver includes a first transmitter and a first receiver. The transmission component includes a gear, and the workstation positioning member includes a rib disposed on the outer ring of the gear. The rib has openings corresponding to the workstation positions. When the rib on the outer ring of the gear passes through the signal path between the first transmitter and the first receiver, the first receiver cannot receive the signal sent by the first transmitter because the rib blocks signal transmission. When the opening on the rib on the outer ring of the gear passes through the signal path between the first transmitter and the first receiver, the first receiver can receive the signal sent by the first transmitter because the opening on the rib on the outer ring of the gear does not block signal transmission. Therefore, the workstation position signal received by the first signal transmitter and receiver is a signal whose signal changes from zero to positive. Simultaneously, by determining the change in signal from zero to positive, the first signal transmitter and receiver can determine that the valve core has rotated to the opening on the rib corresponding to each workstation position, thereby enabling the water softening device to perform the corresponding function.

[0109] In one embodiment, during the process of controlling the transmission of the transmission component, a signal of a shielding member corresponding to each station position on the station positioning member passing through a station detection element is obtained to obtain a station position signal.

[0110] Specifically, the workstation detection element includes a first signal transmitter and receiver, which can be a photoelectric switch. The first signal transmitter and receiver includes a first transmitter and a first receiver. The workstation positioning member includes a shield corresponding to each workstation position. When the shield corresponding to each workstation position does not pass through the signal path between the first transmitter and the first receiver, the first receiver can receive the signal sent by the first transmitter. When the shield corresponding to each workstation position passes through the signal path between the first transmitter and the first receiver, the shield blocks the signal transmission and the first receiver cannot receive the signal sent by the first transmitter. Therefore, the workstation position signal received by the first signal transmitter and receiver is a signal whose signal changes from presence to absence. Simultaneously, by determining the change from presence to absence, the first signal transmitter and receiver can determine that the valve core has rotated to the shield corresponding to each workstation position, thereby confirming that the valve core has rotated to the corresponding workstation position, thereby enabling the water softening device to perform the corresponding function.

[0111] S1004: Determine the workstation position identifier corresponding to the workstation position signal according to the workstation position signal.

[0112] Among them, the work position identifier can be used to indicate the work position of the valve core. For example, during the transmission process of the transmission component, after the work position detection element obtains the work position signal corresponding to the water supply work position of the valve core, it can send information indicating the water supply work position of the valve core corresponding to the work position signal to the controller. After the controller receives the information indicating the water supply work position of the valve core corresponding to the work position signal, it can set and record the identifier corresponding to the water supply work position and determine the identifier as the work position identifier corresponding to the work position signal when the valve core is in the water supply work position. It can be understood that when the work position is different, the identifier corresponding to the work position is also different.

[0113] S1006: After the water softening device is powered on again, the valve core is controlled to rotate to the target position corresponding to the recorded position mark.

[0114] In combination with S1004, an example is that if the work position signal recorded by the controller when the valve core is in the position corresponds to the work position identifier A, according to the correspondence between the work position identifier and the work position of the valve core, then according to the work position identifier A, it can be determined that the work position of the valve core before power failure is the water supply position. In this way, after the softening water equipment is powered on again, the valve core can be rotated to the water supply position.

[0115] In summary, Figure 10In the embodiment shown, by obtaining a work position signal corresponding to the work position of the valve core of the water softening device, the work position identifier corresponding to the work position signal is determined based on the work position signal, and after the water softening device is powered on again, the valve core is controlled to rotate to the target work position corresponding to the recorded work position identifier. In this way, it can be ensured that the work position of the valve core before the water softening device is powered off and after it is powered on again is the same, thereby ensuring the user's usage experience of the water softening device, and at the same time expanding the usage scenarios of the water softening device, and solving the problem that the water softening device cannot provide soft water to the user after it is powered on again.

[0116] exist Figure 10 Based on the embodiment shown, in one embodiment, the controller may include a counter. After receiving the work station position signal from the work station detection element, the controller may update the count value of the counter according to the work station position signal to obtain an updated count value, and may determine the updated count value as the work station position identifier corresponding to the work station position signal.

[0117] In one example, during the transmission of the transmission component, the position detection element obtains the position position signal corresponding to the water supply position of the valve core, and sends the position position signal to the controller. After the controller receives the position position signal, it can count to 1 in the counter, and the count value 1 can be used as the position position identifier of the position position signal when the valve core is in the water supply position; during the continued transmission of the transmission component, the position detection element obtains the position position signal corresponding to the backwash position of the valve core, and sends the position position signal to the controller. After the controller receives the position position signal, it can add 1 to the previous count value stored in the counter. At this time, the count value in the counter is 2, and the count value 2 can be used as the position position identifier of the position position signal when the valve core is in the backwash position, and so on.

[0118] exist Figure 10 Based on the content shown in FIG, in one embodiment, the transmission component is further provided with a reset positioning member that rotates synchronously with the transmission component, such as Figure 11 As shown, a flow chart of a method for controlling a soft water device is provided, and the flow chart is applied to Figure 2 Taking the controller 202 in the example as an example, the following steps may be included:

[0119] S1102, in the process of controlling the transmission of the transmission component, obtaining a signal when the reset positioning member passes through the station detection element to obtain a reset position signal.

[0120] In one embodiment, during the process of controlling the transmission of the transmission component, a signal is obtained when the projected portion of the reset positioning member corresponding to the reset position passes through the station detection element to obtain a reset position signal.

[0121] Specifically, the workstation detection element includes a second signal transmitter and receiver, which can be a photoelectric switch. The second signal transmitter and receiver includes a second transmitter and a second receiver. The transmission component includes a gear, and the reset positioning member includes a rib provided on the inner ring of the gear. There is an opening portion on the rib corresponding to the reset position, and the opening portion is the transmissive portion. When the rib on the inner ring of the gear passes through the signal path between the second transmitter and the second receiver, the rib on the inner ring of the gear blocks the transmission of the signal, and the second receiver cannot receive the signal sent by the second transmitter. When the opening portion on the rib on the inner ring of the gear passes through the signal path between the second transmitter and the second receiver, the opening portion on the rib on the inner ring of the gear does not block the transmission of the signal, and the second receiver can receive the signal sent by the second transmitter. Therefore, the reset position signal received by the second signal transmitter and receiver is a signal whose signal change trend is from nothing to something.

[0122] In one embodiment, during the process of controlling the transmission of the transmission component, a reset position signal can be obtained by acquiring a signal when a shielding member corresponding to the reset position on the reset positioning member passes through a station detection element.

[0123] Specifically, the workstation detection element includes a second signal transmitter and receiver, which can be a photoelectric switch, and the second signal transmitter and receiver includes a second transmitter and a second receiver. The reset positioning member includes a shielding member corresponding to the reset position. When the shielding member corresponding to the reset position does not pass through the signal path between the second transmitter and the second receiver, the second receiver can receive the signal sent by the second transmitter. When the shielding member corresponding to the reset position passes through the signal path between the second transmitter and the second receiver, the second receiver cannot receive the signal sent by the second transmitter because the shielding member blocks the transmission of the signal. Therefore, the reset position signal received by the second signal transmitter and receiver is a signal whose signal change trend is from signal presence to signal absence.

[0124] S1104: Reset the workstation position identifier corresponding to the recorded workstation position signal according to the reset position signal.

[0125] The reset position signal instructs the controller to reset the work position identifier corresponding to the recorded work position signal. For example, the reset position signal may instruct the controller to reset the work position identifier recorded in the counter. Thus, after the reset, the valve core's current work position can be determined again by reusing the recorded work position identifier.

[0126] In one example, the valve core in a water softening device may be located in seven positions, namely the water supply position, backwash position, jet position 1, slow wash position, jet position 2, water replenishment position, and forward wash position. The counter stores a count value each time, and each count value corresponds to a different position. For example, count value 1 corresponds to the water supply position, count value 2 corresponds to the backwash position, count value 3 corresponds to jet position 1, and so on. After the controller accumulates the count value corresponding to the last position through the counter, if it is not reset, when the valve core continues to rotate to the next position, the count value in the counter at this time is 8, and the position of the valve core cannot be determined based on the count value 8. Therefore, by resetting, the position position identifier (i.e., the count value) in the counter is reset, so that the position position identifier corresponding to the position position signal when the valve core is in the position is recorded again, so that the position of the valve core can be determined based on the recorded position position identifier.

[0127] It can be understood that the correspondence between the above-mentioned count value and the position of the valve core can be set according to the actual application scenario, and this embodiment does not limit it.

[0128] In summary, Figure 11 In the embodiment shown, a reset position signal is obtained by obtaining a signal when the reset positioning member passes through the work position detection element during the process of controlling the transmission of the transmission component, and the work position identifier corresponding to the recorded work position signal is reset according to the reset position signal. In this way, after resetting, the work position of the valve core can be determined again by using the recorded work position identifier, thereby avoiding the situation where the work position of the valve core is judged to be incorrect.

Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and these steps can be executed in other orders.
