Description

Technical Field

[0001] The present invention relates to the technical field of valve body structures, and in particular to a diverter valve with an integrated waterway switch, a waterway control method, and a waterway cleaning method. Background Art

[0002] In the existing smart toilet cleaning water circuit, the function of the water circuit switch is realized by a solenoid valve as an independent component. The solenoid valve component controls the on-and-off of the water circuit through the solenoid switch and the pilot valve structure. As an independent component used in the cleaning water circuit system, there are independent product cost requirements and system control requirements. Therefore, the design investment cost, production and maintenance costs of the product are greatly increased, and the burden of system control is increased. It is necessary to separately add a control command interface, which occupies system control resources and reduces system stability.

[0003] And in the existing intelligent toilet cleaning water circuit, such as Figure 1 As shown, the solenoid valve with water circuit switching function needs to be at the front end of the cleaning water circuit, and the switch operation at the front end of the water circuit will inevitably cause a delay in the flushing switch effect at the end of the water circuit, and the pilot valve structure itself is not sensitive enough. Therefore, the existing solenoid valve type water circuit switch has obvious delay phenomenon, which can easily cause users to have a poor experience when using the cleaning function. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a diverter valve with an integrated water circuit switch that has a simple structure, flexible and convenient adjustment, and integrated functional settings; a water circuit control method using the diverter valve that has high adjustment sensitivity, eliminates delays, and optimizes user experience; and a cleaning water circuit using the diverter valve that has strong stability and obvious cost optimization.

[0005] In order to solve the above technical problems, the technical solution proposed by the present invention is:

[0006] A diverter valve with an integrated water circuit switch comprises a valve core, a valve seat and a rotary drive component, wherein the end surface of the valve seat in contact with the valve core is provided with a plurality of water outlets connected to various water passages, and the end surface of the valve core in contact with the valve seat is provided with a water through hole connected to a water inlet, the rotary drive component drives the valve core to rotate relative to the valve seat, the water outlets and the water through holes are distributed on a circular ring with the relative rotation center as the center, and also comprises a blocking component for blocking the water inlet when the valve core rotates to a set position where the water through hole and the water outlets are not connected, and the blocking component rotates synchronously with the valve core.

[0007] As a further improvement of the above-mentioned diverter valve with integrated water circuit switch:

[0008] It also includes an upper valve body and a rotating shaft. The upper valve body is cylindrical and sleeved on the outside of the rotating shaft, and the water inlet is opened on its side wall; the rotating shaft is connected between the output end of the motor and the valve core, and the blocking member is arranged on one side of the rotating shaft.

[0009] Each of the water outlets is distributed in a first fan-shaped area with the relative rotation center as the center, and the set position is located in a second fan-shaped area that is complementary to the first fan-shaped area in a circle; the inner diameter R1 of the side wall corresponding to the first fan-shaped area in the upper valve body is greater than the distance L from the outer surface of the blocking member to the rotation center, and the side wall corresponding to the second fan-shaped area includes a gradual arc-shaped inner diameter that gradually changes from R2 less than L to R1; the water inlet is located at the side wall corresponding to the second fan-shaped area in the upper valve body.

[0010] The blocking member comprises a supporting member and a rubber member. The supporting member extends from the side of the rotating shaft to form a rod or plate shape parallel to the rotating shaft. The rubber member is sleeved on the outside of the supporting member.

[0011] One end of the upper valve body is fitted to and sealed with the end face of the rotary drive member, and the other end is sleeved to and sealed with the end face of the valve seat. The valve core is also arranged inside the upper valve body. One end of the rotating shaft is connected to the output end of the rotary drive member extending into the upper valve body, and the other end is connected to the upper valve body.

[0012] The rotating shaft is a stepped shaft, and an elastic member is provided between the step surface of the step and the end surface of the valve core for supporting.

[0013] A waterway control method is implemented using the diverter valve with integrated waterway switch, and the steps include:

[0014] S1: Open the water channel: The rotary drive element drives the valve core to rotate away from the set position, and the blocking element rotates synchronously with the valve core and opens the water inlet, and the water inlet is connected to the water hole;

[0015] S2: Connecting the common water passage: The rotary drive continues to drive the valve core to rotate until the water hole rotates to connect with the water outlet for standby water, and water flows in from the water inlet, passes through the water hole and the water outlet in sequence and reaches the water passage for standby water;

[0016] S3: Close the water circuit: After the water is used, the rotary drive member drives the valve core to rotate to the set position, the blocking member blocks the water inlet, and the water circuit is closed.

[0017] A cleaning water circuit comprises a tap water inlet passage, a pressure reducing component, a functional component, a washer and a control module, and also comprises a diverter valve of the above-mentioned integrated water circuit switch, wherein the tap water inlet passage, the pressure reducing component, the functional component, the diverter valve of the integrated water circuit switch and the washer are connected in sequence, the functional component, the washer and the diverter valve of the integrated water circuit switch are all communicatively connected with the control module, and the control module realizes the on-off of the cleaning water circuit by controlling the rotary drive component of the diverter valve of the integrated water circuit switch.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] The diverter valve of the integrated water circuit switch of the present invention comprises a valve core, a valve seat and a rotary drive member, a plurality of water outlets connected to various water supply passages are provided on the end surface of the valve seat in contact with the valve core, a water through hole connected to the water inlet is provided on the end surface of the valve core in contact with the valve seat, the rotary drive member drives the valve core to rotate relative to the valve seat, and the water outlets and the water through holes are distributed on a circle with the relative rotation center as the center. During the rotation process, the water through holes can be connected to the water outlets, so that the water flow entering the water inlet is output to the various water supply passages to realize water use.

[0020] Unlike the existing conventional diverter valve, the diverter valve of the present invention also includes a blocking member that blocks the water inlet when the valve core rotates to the set position where the water hole and each water outlet are not connected, and the blocking member rotates synchronously with the valve core. That is, when the valve core rotates to the set position, the blocking member blocks the water inlet to achieve the waterway shut-off function; when the valve core rotates away from the set position, the blocking member releases the water inlet, and the waterway is connected at this time, and can be transported to any water outlet, and because the set position does not interfere with the position of any water outlet, there will be no problem of closing the waterway when a water channel needs water. This setting structure enables the diverter valve of the present invention to integrate the waterway switch function, and the switch function does not need to be realized by a separate control device and a switch component, but is directly set inside the diverter valve and can be realized by the rotary drive component that originally drives the diverter valve, so there is no need to add additional separate components, which greatly reduces the cost and simplifies the control method.

[0021] The method of using the diverter valve to control the water path also has the above advantages, and because the switch is integrated inside the diverter valve, the control process is faster and more flexible, effectively eliminating the delay phenomenon of the existing switch components and optimizing the user experience.

[0022] The cleaning water circuit using this diverter valve can directly open and close the water circuit through the integrated switch arranged in the diverter valve at the end of the water circuit, thereby further eliminating the water circuit on-off delay phenomenon, and the control sensitivity of the cleaning water circuit is greatly optimized. There is no need for separate electromagnetic switch components, the production cost is reduced, and the water circuit structure is more miniaturized. In addition, the removal of separate electromagnetic switch components also saves the system's control resources, saves the hardware interface requirements of the electromagnetic switch valve, reduces the burden on the control module, and makes the entire system more stable and reliable.

[0033] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively and meticulously below in conjunction with the accompanying drawings and preferred embodiments of the present invention, but the protection scope of the present invention is not limited to the following specific embodiments.

[0034] Example:

[0035] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the diverter valve of the integrated water circuit switch of this embodiment includes a valve core 1, a valve seat 2 and a rotary drive member 3. A plurality of water outlets 21 connected to each water passage are provided on the end surface of the valve seat 2 in contact with the valve core 1, and a water through hole 11 connected to the water inlet 41 is provided on the end surface of the valve core 1 in contact with the valve seat 2. The rotary drive member 3 drives the valve core 1 to rotate relative to the valve seat 2. The water outlets 21 and the water through holes 11 are distributed on a circular ring with the relative rotation center as the center. During the rotation process, the water through holes 11 can be connected with the water outlets 21, so that the water flow entering the water inlet 41 is output to each water passage to realize water use.

[0036] Different from the conventional diverter valve, the diverter valve of this embodiment further includes a blocking member 51 for blocking the water inlet 41 when the valve core 1 rotates to the set position where the water hole 11 and each water outlet 21 are not connected. Figure 3 and Figure 4 As shown, the blocking member 51 rotates synchronously with the valve core 1. That is, when the valve core 1 rotates to the set position, the blocking member 51 blocks the water inlet 41. Figure 7 As shown, the waterway shut-off function is realized; when the valve core 1 rotates away from the set position, the blocking member 51 releases the water inlet 41, and the waterway is connected at this time, as shown in FIG. Fig.10 As shown, it can be delivered to any water outlet 21, and because the set position does not interfere with the position of any water outlet 21, there will be no problem of closing the water channel when a certain water channel needs water. This setting structure enables the diverter valve of this embodiment to integrate the water channel switch function, and the switch function does not need to be realized by a separate control device and a switch component, but is directly set inside the diverter valve, and can be realized by the rotary drive member 3 that originally drives the diverter valve. Therefore, there is no need to add additional separate components, which greatly reduces the cost and simplifies the control method. In addition, the diverter valve is set at the end of the water channel, and the switch integrated on the diverter valve at the end can open and close the water channel more sensitively, avoiding problems such as water flow in the water channel from the front end to the end after the front end has been closed.

[0037] The diverter valve of this embodiment further comprises an upper valve body 4 and a rotating shaft 5. The upper valve body 4 is cylindrical. Figure 3 As shown, it is sleeved on the outside of the rotating shaft 5, and a water inlet 41 is opened on its side wall; the rotating shaft 5 is connected between the output end of the motor and the valve core 1, and a blocking member 51 is provided on one side thereof. Through the synchronous rotation of the rotating shaft 5 and the valve core 1, the blocking member 51 can rotate inside the upper valve body 4, thereby blocking the water inlet 41 located on the side wall of the upper valve body 4.

[0038] In the present embodiment, each water outlet 21 is distributed in a first sector-shaped area with the relative rotation center as the center, and the set position is located in a second sector-shaped area which is complementary to the first sector-shaped area in a circle. This arrangement can avoid interference between the set position and the water outlet 21, and the valve core 1 rotates and the water hole 11 will not pass through the set position when switching and docking with each water outlet 21. The inner diameter R1 of the side wall corresponding to the first sector-shaped area in the upper valve body 4 is greater than the distance L from the outer side of the sealing member 51 to the rotation center, and the side wall corresponding to the second sector-shaped area includes a gradual arc-shaped inner diameter that gradually changes from R2 which is less than L to R1; the water inlet 41 is located at the side wall corresponding to the second sector-shaped area in the upper valve body 4. When the sealing member 51 enters the second sector-shaped area, as Figure 7 As shown, the blocking member 51 will form an interference fit with the inner wall of the upper valve body 4, and block the water inlet 41 and the gap around it at the set position to ensure that the water path is completely shut off. Figure 8 and Fig. 9 As shown, at this time, since the water hole 11 is not connected to any water outlet 21, the thoroughness of the water circuit shutoff is further ensured. Fig.10 As shown, there is a gap between the inner wall of the upper valve body 4 and the blocking member 51. Fig.11 and Fig.12 As shown, the water flow from the water inlet 41 can enter the water hole 11 to achieve water flow supply.

[0039] In this embodiment, Figure 4 As shown, the blocking member 51 includes a support member 511 and a rubber member 512. The support member 511 extends from the side of the rotating shaft 5 to form a rod or plate parallel to the rotating shaft 5. The rubber member 512 is sleeved on the outside of the support member 511. The rubber member 512 has a certain elasticity and flexibility, so it can ensure that the water inlet 41 is completely sealed. The support member 511 provides support force for the rubber member 512 to ensure the shape of the rubber member 512.

[0040] In this embodiment, one end of the upper valve body 4 is fitted and connected to the end surface of the rotary drive member 3 and sealed, and the other end is sleeved and connected to the end surface of the valve seat 2 and sealed. The valve core 1 is also arranged inside the upper valve body 4. One end of the rotating shaft 5 is connected to the output end of the rotary drive member 3 extending into the upper valve body 4, and the other end is connected to the upper valve body 4. The rotating shaft 5 is a stepped shaft, and an elastic member 52 is arranged between the step surface of the step and the end surface of the valve core 1. The elastic member 52 can support the valve core 1 so that the end surface of the valve core 1 and the end surface of the valve seat 2 are closely fitted.

[0041] The water circuit control method of this embodiment is implemented by using the diverter valve with integrated water circuit switch, so it also has the above advantages. Moreover, since the switch is integrated inside the diverter valve, the control process is faster and more flexible, effectively eliminating the delay phenomenon of the existing switch components and optimizing the user experience. The steps include:

[0042] S1: Opening the water path: The rotary drive member 3 drives the valve core 1 to rotate away from the set position, and the blocking member 51 rotates synchronously with the valve core 1 and opens the water inlet 41, and the water inlet 41 is connected to the water hole 11;

[0043] S2: Connecting the common water passage: the rotary drive member 3 continues to drive the valve core 1 to rotate until the water hole 11 rotates to connect with the water outlet 21 for standby water, and water flows in from the water inlet 41, passes through the water hole 11 and the water outlet 21 in sequence and reaches the water passage for standby water;

[0044] S3: Closing the water circuit: After the water is used, the rotary drive member 3 drives the valve core 1 to rotate to reach the set position, and the blocking member 51 blocks the water inlet 41, and the water circuit is closed.

[0045] The cleaning waterway of this embodiment is as follows Fig.13 As shown, it includes a tap water inlet passage, a pressure reducing component, a functional component, a washer and a control module, and also includes a diverter valve of the above-mentioned integrated water circuit switch. The tap water inlet passage, the pressure reducing component, the functional component, the diverter valve of the integrated water circuit switch and the washer are connected in sequence, and the functional component, the washer and the diverter valve of the integrated water circuit switch are all communicatively connected to the control module, and the control module realizes the opening and closing of the cleaning water circuit by controlling the rotary drive component 3 of the diverter valve of the integrated water circuit switch.

[0046] The cleaning water circuit using this diverter valve can directly open and close the water circuit through the integrated switch arranged in the diverter valve at the end of the water circuit, thereby further eliminating the water circuit on-off delay phenomenon, and the control sensitivity of the cleaning water circuit is greatly optimized. There is no need for separate electromagnetic switch components, the production cost is reduced, and the water circuit structure is more miniaturized. In addition, the removal of separate electromagnetic switch components also saves the system's control resources, saves the hardware interface requirements of the electromagnetic switch valve, reduces the burden on the control module, and makes the entire system more stable and reliable.

[0047] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. For those skilled in the art, improvements and changes obtained without departing from the technical concept of the present invention should also be regarded as the protection scope of the present invention.
