Detailed Description

In the related art gas water heaters, when a user uses water, the gas water heater detects a water flow signal, the fan is started to clean the water before, waste gas in the water heater is discharged through the smoke pipe, the air pressure switch detects the closing of the air pressure switch, the air valve is opened again to ignite and burn, and water flows out through the water heater after being heated. The time from the boiling water of a user to the ignition and combustion of the water heater is about 3-5 s, and the time from the boiling water of the user to the constant-temperature hot water flowing out at the bathing place is generally 20-30 s.

However, when the gas water heater is used again after being suspended for a short time, that is, when a user uses water for a second time in a short time, because part of the water remains in the water outlet end of the water heater after the last water usage, hot water with a higher temperature flows out from the water outlet end of the water heater first. And because the above-mentioned need wait for fan to carry out preceding scavenging before ignition, and ignition burning needs 3 ~ 5s. Therefore, after the residual hot water flows out, the water with lower temperature flows out from the water outlet end of the water heater. After the ignition and combustion of the water heater are finished, water with the target water temperature can flow out from the water outlet end of the water heater.

Fig. 1 is a schematic view of a water heater provided in an embodiment of the present application, fig. 2 is a schematic view of another water heater provided in an embodiment of the present application, and arrows in fig. 1 and fig. 2 indicate a flow direction of liquid. Referring to fig. 1 and 2, the water heater 10 may have a water inlet end 101, a hot water end 102, and a water outlet end 103.

Illustratively, the inlet end 101 may have an inlet branch pipe 104, the hot water end 102 may have an outlet branch pipe 105, and the outlet end 103 may have an outlet manifold 107. A bypass branch pipe 106 can be communicated between the water inlet branch pipe 104 and the water outlet branch pipe 105. Cold water may be delivered through the intake manifold 108 while the water heater 10 is in operation. The output of the intake manifold 108 may be in communication with the intake branch 104 and the bypass branch 106, respectively. So that a part of cold water enters the water inlet end 101 of the water heater 10 through the water inlet branch pipe 104, a part of cold water is mixed with hot water flowing out from the water outlet branch pipe 105 through the bypass branch pipe 106, and the mixed water can flow out to a user through the water outlet header pipe 107.

However, in actual use, when the user uses water for the second time, if the amount of cold water mixed with the hot water in the hot water end 102 is increased, the temperature of the water flowing out from the water outlet end 103 of the water heater 10 can be decreased; reducing the amount of cold water flowing into the water heater 10 increases the heat exchange efficiency of the heat exchanger of the water heater 10, and thus increases the temperature of the water flowing out of the water outlet 103 of the water heater 10. In this way, when the user uses water for the second time, the temperature of the water flowing out of the water outlet end 103 of the water heater 10 is close to the target water temperature, so as to improve the shower experience of the user.

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments.

Example one

Fig. 3 is a schematic diagram of a water inlet module provided in an embodiment of the present application. Referring to fig. 1-3, the water inlet module provided in the embodiment of the present application may include a memory 61, a timer 62, a valve 9, and a controller 7. The memory 61 may be mounted to the water heater 10 and may record the last time the user finished using water. The timer 62 may be installed in the water heater 10 and may obtain the user's current water usage start time. At least a portion of the valve 9 may be disposed at the water inlet end 101 and may regulate the flow of water into the water inlet end 101. At least a part of the valve 9 can be disposed at the hot water end 102, and can adjust the flow of water flowing into the hot water end 102. The controller 7 may calculate a time interval between a current time when the user starts to use water and a last time when the user finishes using water, and may control the valve 9 to make the liquid flow into the water inlet 101 of the water heater 10 at a smaller flow rate and flow into the hot water end 102 of the water heater 10 at a larger flow rate when the time interval is smaller than a preset time period.

Specifically, the memory 61 can obtain the time of the timer 62 when the user closes the valve 9 of the outlet end 103 (or the shower head) of the water heater 10, and store the time as the last time the user used water. The memory 61 may be implemented by any type of volatile or non-volatile storage device or combination thereof, such as static random access memory 61 (SRAM), electrically erasable programmable read-only memory 61 (EEPROM), erasable programmable read-only memory 61 (EPROM), programmable read-only memory 61 (PROM), read-only memory 61 (ROM), magnetic memory 61, flash memory 61, a magnetic or optical disk.

In addition, the timer 62 can obtain the current time when the user opens the valve 9 of the valve 9 (or the shower head) at the outlet end 103 of the water heater 10, and the current time is the current water consumption starting time of the user. The timer 62 may be a timer that requires the user to periodically calibrate the time. The timer 62 may also send the acquisition request information to the server, and the server returns the acquired current time. The current time may also be obtained from the network from the time.

In addition, the controller 7 can obtain the last water usage end time of the user sent by the memory 61 and the current water usage start time of the user sent by the timer 62 when the valve 9 of the valve 9 (or the shower head) of the outlet end 103 of the water heater 10 is opened by the user. The controller 7 may calculate the difference between the current water usage starting time of the user and the last water usage ending time of the user to obtain the time interval between two adjacent times of water usage of the user. The controller 7 may compare the calculated time interval with a preset time period, and if the time interval is smaller than the preset time period, the controller 7 may control the valve 9 to decrease the water flow flowing into the water inlet end 101 and increase the water flow flowing into the hot water end 102. If the time interval is greater than the preset time period, the water flow flowing into the water inlet end 101 and the water flow flowing into the hot water end 102 are kept unchanged.

It should be noted that the water inlet module provided by the present application can have at least two states. Wherein, the first state: the liquid flows into the water inlet end 101 of the water heater 10 at a relatively large flow rate and into the hot water end 102 of the water heater 10 at a relatively small flow rate. Namely, a state of large water inflow and small bypass amount. The second state: the liquid flows into the water inlet end 101 of the water heater 10 at a relatively small flow rate and into the hot water end 102 of the water heater 10 at a relatively large flow rate. Namely, a state of small water inflow and large bypass amount. The larger and smaller mentioned in this paragraph are compared in two states. That is, in the second state, the amount of water flowing into the water inlet end 101 of the water heater 10 is reduced and the amount of water flowing into the hot water end 102 of the water heater 10 is increased as compared to the first state. When the user uses water for the second time, the water inlet module can operate for a period of time in the second state. After the water inlet module operates for a period of time, the water inlet module can be switched from the second state to the first state. The time period for which the water inlet module operates in the second state may be a preset value. Alternatively, the water inlet module can be switched from the second state to the first state after ignition and heating.

Alternatively, the controller 7 may control the valve 9 to make the liquid flow into the water inlet end 101 of the water heater 10 at a smaller flow rate and flow into the hot water end 102 of the water heater 10 at a smaller flow rate when the operation state of the water heater 10 is stable, the heating state of the water heater 10 is at the maximum value, and the temperature of the water outlet end 103 of the water heater 10 is less than the preset temperature value.

Specifically, the water inlet module provided by the application can further have a third state: the liquid flows into the water inlet end 101 of the water heater 10 at a relatively small flow rate and into the hot water end 102 of the water heater 10 at a relatively small flow rate. Namely, a state of small water inflow and small bypass amount. When the water heater 10 operates in the first state for a period of time or hot water with stable temperature flows out from the water outlet end 103 of the water heater 10, and the proportional valve for regulating and controlling the gas of the water heater 10 is adjusted to the maximum gear, however, when the water outlet temperature of the water heater 10 measured by the temperature detector arranged at the water outlet end 103 of the water heater 10 is lower than a preset temperature value, the water inlet module can be converted from the first state to the third state to increase the temperature of the water outlet end 103 of the water heater 10.

Referring to fig. 1, the valve 9 may be alternatively arranged in the following ways:

in one possible implementation manner, referring to fig. 1, the number of the valves 9 may be multiple, each valve 9 may be an inlet-outlet valve 91, each inlet-outlet valve 91 may have a first water passage port and a water outlet port, and the inlet-outlet valve 91 may change the flow rate of the pipeline communicated with the openings by adjusting the opening degree of the water outlet port or the first water passage port. The valve 9 may include two one-in-one-out valves 91, wherein one-in-one-out valve 91 may be disposed in the bypass branch 106 to regulate the flow of the bypass branch 106; another in-out valve 91 may be provided on the inlet manifold 108 or the inlet branch 104. When an inlet-outlet valve 91 is disposed in the inlet manifold 108 as shown in fig. 1, the inlet-outlet valve 91 can regulate the flow rate of the inlet manifold 108. When an inlet-outlet valve 91 is provided in inlet branch 104, inlet-outlet valve 91 may regulate the flow rate of inlet branch 104. Of course, valve 9 may also include three in-and-out valves 91, and bypass branch 106, inlet branch 104, and inlet manifold 108 may each be provided with one in-and-out valve 91.

In another possible implementation, referring to fig. 2, the valve 9 may comprise at least one-in-two-out valve 92. The one-in two-out valve 92 may have a first water passage port and two water outlet ports, and the one-in two-out valve 92 may change the flow rate of the pipe communicating with the openings by changing the opening degrees of the first water passage port and/or the water outlet ports. The first water inlet may be connected to the water inlet manifold 108, and the two water outlets may be connected to the water inlet branch 104 and the bypass branch 106, respectively.

The one-in two-out valve 92 can adjust the opening degree of two openings, and can also adjust the opening degree of three openings. In order to better control the flow rate, when the one in two out valve 92 can only adjust the opening degree of the two openings, a one in one out valve 91 is provided in the upstream line or the downstream line of the one in two out valve 92. For example, when the one-in two-out valve 92 can only adjust the opening degree of two outlets, the one-in one-out valve 91 may be provided upstream of the one-in two-out valve 92. In the case where the one-in-two-out valve 92 can adjust only the opening degree of one outlet and one inlet, and one outlet is communicated with the water inlet branch pipe 104, a one-in-one-out valve 91 may be provided in the bypass branch pipe 106. Similarly, when the two inlet and outlet valves can only adjust the opening degree of one outlet and one inlet, and one outlet is communicated with the bypass branch pipe 106, the one inlet and one outlet valve 91 can be arranged in the water inlet branch pipe 104.

Fig. 4-28 show five configurations of the one-in two-out valve 92, and a possible implementation of the one-in two-out valve 92 will be described with reference to fig. 4-28.

Fig. 4 is a front view of a two-in two-out valve 92 according to an embodiment of the present disclosure. Referring to fig. 4, the one-in-two-out valve 92 may include a valve body 1, and the valve body 1 may have an axial first water passage port 12 and a closed end 11, that is, one axial end of the valve body 1 is closed for mounting the driver 5; the other end of the valve body 1 in the axial direction has an opening to form a first water passage port 12. Exemplarily, in fig. 4, the valve body 1 may include a cylinder 19 and a cover plate 18. The cylinder 19 may be disposed in a vertical direction, and both upper and lower ends of the cylinder 19 may have openings. The cover 18 can cover the upper opening of the cylinder 19 to form a closed end 11 at the upper end of the cylinder 19, and the lower end of the cylinder 191 forms the first water passage 12. Of course, the valve body 1 may have other structures for forming the first water passage port 12 and the closed end 11, and the embodiment of the present application is only illustrated by the structure of the cylinder 19 shown in fig. 4, and is not particularly limited.

Referring to fig. 4-28, the side wall of the valve body 1 between the first water passage port 12 of the valve body 1 and the closed end 11 of the valve body 1 may be provided with a second water passage port 13 and a bypass water outlet port 14, at least part of the valve core assembly 2 is arranged in the valve body 1 and is movable relative to the valve body 1, and the valve core assembly 2 is used for changing the opening degrees of two of the second water passage port 13, the bypass water outlet port 14 and the first water passage port 12. Fig. 4 to 28 show the valve body 1 as an example in a space surrounded by the cylinder 19 and the cover plate 18.

The following description will be given by taking the example that the valve core assembly 2 shown in fig. 4 to 13 only changes the opening degrees of the second water passage opening 13 and the bypass water outlet 14, and the way of changing the second water passage opening 13 and the first water passage opening 12 or changing the bypass water outlet 14 and the first water passage opening 12 for the valve core assembly 2 can be obtained by referring to the way of changing the second water passage opening 13, the bypass water outlet 14 and the first water passage opening 12 (corresponding to fig. 14 to 28) of the valve core assembly 2 mentioned below, which is not described first.

Referring to fig. 4-13, the second water outlet 13 and the bypass water outlet 14 may be disposed on a side wall of the cylinder 19, the valve core assembly 2 may include a valve sleeve 22, and the valve sleeve 22 may change the opening degrees of the second water outlet 13 and the bypass water outlet 14 by rotating in the valve body 1 as shown in fig. 4-11, or the valve sleeve 22 may change the opening degrees of the second water outlet 13 and the bypass water outlet 14 by moving in the valve body 1 as shown in fig. 12 and 13.

Referring to fig. 4-11, in one example, the second water outlet 13 and the bypass water outlet 14 are disposed at different positions in the circumferential direction of the side wall of the cylinder 19. Fig. 4 to 11 show the second water outlet 13 disposed on the left side of the cylinder 19, and the bypass water outlet 14 disposed on the right side of the cylinder 19.

The valve sleeve 22 is rotatably disposed in the accommodating space formed by the cylinder 19 and the cover 18, and the rotation axis of the valve sleeve 22 can be disposed along the axis of the cylinder 19. I.e. the axis of rotation of the valve sleeve 22 is parallel or coincident with the axis of the barrel 19. The interior of the valve sleeve 22 may have a center hole 221, and the center hole 221 may be opposite to the first water passage port 12 of the valve body 1 and communicate with the first water passage port 12 of the valve body 1. The side wall of the valve housing 22 has a communication groove 222 communicating with the center hole 221, and the communication groove 222 is available to oppose the second water communication port 13 so that the communication groove 222 communicates with the second water communication port 13. The communication groove 222 may be used to oppose the bypass outlet 14 such that the communication groove 222 communicates with the bypass outlet 14.

Specifically, the communication groove 222 is fitted to the center hole 221 to communicate the second water passage port 13, the bypass water outlet port 14, and the first water passage port 12 of the valve body 1. The communication groove 222 may be arranged in the following manners:

in one possible implementation, referring to fig. 6 to 9, the communication groove 222 may include at least a first communication groove 223 and a second communication groove 224. The first and

second communication grooves

223 and 224 may have a predetermined interval in the circumferential direction of the valve housing 22. The first communicating groove 223 may be used to communicate with the second water outlet 13, and the second communicating groove 224 may be used to communicate with the bypass water outlet 14.

The hollow arrows shown in fig. 7-9 are the flow direction of the liquid. Referring to fig. 7-9, the first water passage port 12 of the valve body 1 may be a first water passage port of a one-inlet-two-outlet valve, and the first water passage port 12 of the valve body 1 may be communicated with the water inlet manifold 108 through the water inlet pipe 15; the second water through opening 13 may be a second water through opening of a one-inlet two-outlet valve, the first water through opening 12 of the valve body 1, the central hole 221 of the valve housing 22, the first communicating groove 223 of the valve housing 22, and the second water through opening 13 may form a water inlet flow passage, and the second water through opening 13 may communicate with the water inlet branch pipe 104 in fig. 2 through the water outlet pipe 16. The bypass water outlet 14 may be a bypass water outlet of a one-in two-out valve, the first water passage port 12 of the valve body 1, the central hole 221 of the valve sleeve 22, the second communicating groove 224 of the valve sleeve 22, and the bypass water outlet 14 may form a bypass flow path, and the bypass water outlet 14 may communicate with the bypass branch pipe 106 in fig. 2 through the bypass pipe 17.

Of course, the second water passage opening 13 may be a first water passage opening of a one-inlet two-outlet valve, and the first water passage opening 12 of the valve body 1 may be a second water passage opening of a one-inlet two-outlet valve. The second water passage opening 13, the first communication groove 223 of the valve housing 22, the central hole 221 of the valve housing 22, and the first water passage opening 12 of the valve body 1 may form a water inlet flow passage, and the second water passage opening 13 may communicate with the water inlet manifold 108 in fig. 2. The bypass water outlet 14 may be a bypass water outlet of a one-inlet-two-outlet valve, the second water outlet 13, the central hole 221 of the valve sleeve 22, the second communicating groove 224 of the valve sleeve 22, and the bypass water outlet 14 may form a bypass flow channel, and the bypass water outlet 14 may be communicated with the bypass branch pipe 106 in fig. 2 through the bypass pipe 17.

Referring to fig. 7, when the water inlet device 92 is in the first state, the first communicating groove 223 may face the second water passing opening 13, and the facing area is at a large value. That is, the area where the projection of the first communicating groove 223 on the side wall of the cylinder 19 in the radial direction of the cylinder 19 coincides with the second water passage port 13 is at a large value. When the water inlet device 92 is in the first state, the second communicating groove 224 may be directly opposite to the bypass water outlet 14, and the facing area may be at a small value. That is, the area where the projection of the first communicating groove 223 on the side wall of the cylindrical body 19 in the radial direction of the cylindrical body 19 coincides with the second water passing port 13 is at a small value.

Referring to fig. 8 and 9, when the water inlet device 92 is in the second state, the first communicating groove 223 may be opposite to the second water passing opening 13, and the opposite area is at a small value. That is, the area where the projection of the first communicating groove 223 on the side wall of the cylindrical body 19 in the radial direction of the cylindrical body 19 coincides with the second water passing port 13 is at a small value. When the water inlet device 92 is in the second state, the second communicating groove 224 may be directly opposite to the bypass water outlet 14, and the facing area may be at a larger value. That is, the area of the projection of the second communication groove 224 on the side wall of the cylindrical body 19 in the radial direction of the cylindrical body 19, which overlaps with the bypass water outlet 14, is large.

It should be noted that the area of the bypass water outlet 14 may be larger than the area of the second communicating groove 224 as shown in fig. 7 to 9, and of course, the area of the bypass water outlet 14 may be smaller than the area of the second communicating groove 224.

Referring to fig. 8, in order not to excessively affect the water inflow of the water heater 10 in the second state, i.e., in order to ensure the flow rate of the water inflow passage in the second state, the first communicating groove 223 may be lower than the second communicating groove 224 where it communicates with the second water-passing opening 13. That is, in the second state, only the liquid higher than the lower end of the second communication groove 224 flows into the bypass pipe 17 through the second communication groove 224 and the bypass water outlet 14.

Specifically, referring to fig. 9, in the second state, part of the first communicating groove 223 is shielded by the inner surface of the cylinder 19. A portion of the first communicating groove 223 that is not shielded by the inner surface of the cylinder 19 may be opposite to and communicate with the second water passing port 13. Referring to fig. 8, the lower end of the first communication groove 223, which is not partially blocked by the inner surface of the cylinder 19, may be lower than the second communication groove 224. The upper end of part of the first communication groove 223 may be higher than the lower end of the second communication groove 224 and lower than the upper end of the second communication groove 224 as shown in fig. 8. Of course, the upper end of the part of the first communication groove 223 may be lower than the lower end of the second communication groove 224.

In order to realize that the portion of the first communicating groove 223 which is not covered by the inner surface of the cylinder 19 in the second state, that is, the portion of the first communicating groove 223 opposite to the second water passage opening 13 is lower than the second communicating groove 224, the shape of the first communicating groove 223 may be set in the embodiment of the present application:

referring to fig. 5, alternatively, the highest point of at least a portion of the first communicating groove 223 may be gradually inclined upward in a preset direction. The predetermined direction may be a rotational direction in which the valve sleeve 22 is rotated from the first state to the second state. Illustratively, the arrow W in fig. 5 indicates a counterclockwise direction. Referring to fig. 2, the valve sleeve 22 is rotatable in the direction W, i.e., counterclockwise, from the first condition to the second condition. An upper edge line of the first communicating groove 223 may be gradually inclined upward in a counterclockwise direction.

In order to increase the opening size of the first communication groove 223, at least a portion of the first communication groove 223 may be disposed at an upper portion of the sidewall of the valve housing 22, and at least a portion of the first communication groove 223 may be disposed at a lower portion of the sidewall of the valve housing 22. For example, the left edge line of the first connecting groove 223 in fig. 5 may be an arc shape, and the center of the left edge line may be located at the middle right side of the left edge line. That is, the first communication groove 223 may be a pattern symmetrical with respect to the central axis plane of the valve housing 22, and the center of the left side edge line may be located on the central axis plane of the valve housing 22. Wherein the central axial plane of the valve sleeve 22 may be parallel to the bottom surface of the valve sleeve 22 and the distance from the upper end surface of the valve sleeve 22 to the central axial plane is equal to the distance from the lower end surface of the valve sleeve 22 to the central axial plane.

Referring to fig. 7 and 8, alternatively, in order to allow the valve sleeve 22 to rotate relatively stably within the cylinder 19, the outer surface of the side wall of the valve sleeve 22 may contact the inner surface of the cylinder 19, and the outer surface of the valve sleeve 22 may be fitted to the inner surface of the cylinder 19. In order to bring the outer surface of the side wall of the valve sleeve 22 into contact with the inner surface of the water inlet pipe 15, the upper end surface of the valve sleeve 22 may be higher than the highest end of both the second water passage outlet 13 and the bypass water outlet 14. The lower end surface of the valve sleeve 22 may be lower than the lowest end of both the second water outlet 13 and the bypass water outlet 14.

With continued reference to fig. 5-8, to rotate the valve sleeve 22, the valve sleeve 22 may optionally include a side wall and a top wall, the top wall of the valve sleeve 22 may be secured with the valve stem 21. The valve rod 21 can be passed through the cover plate 18 and connected to the actuator 5 arranged outside the cover plate 18. The actuator 5 can drive the valve rod 21 to rotate, so that the valve sleeve 22 rotates. The drive 5 may be in communicative connection with the above mentioned controller 7. The driver 5 can be a motor, the motor can be provided with a motor shaft, the motor shaft can be directly connected with the valve rod 21 in a welding mode, an interference fit mode, a coupling mode and the like, and the motor shaft can also be indirectly connected with the valve rod 21 through a speed reducer and the like.

In order to make the valve rod 21 rotate stably, the sleeve 4 can be accommodated in the accommodating space formed by the cover plate 18 and the cylinder 19. The outer surface of the sleeve 4 may be fixed to the inner surface of the cylinder 19, and the upper surface of the sleeve 4 may abut against the cover plate 18. The valve stem 21 is passed through the sleeve 4 and is rotatable relative to the sleeve 4. The outer surface of the sleeve 4 may be provided with a groove which may receive a sealing ring 8 with the inner surface of the barrel 19 to effect a seal between the sleeve 4 and the inner surface of the barrel 19.

Referring to fig. 7 and 8, to achieve axial retention of the valve sleeve 22 in the barrel 19, the top wall of the valve sleeve 22 may abut the lower surface of the sleeve 4. The lower end of the cylinder 19 may be fixed with the water inlet pipe 15, the water inlet pipe 15 may be coaxially disposed with the cylinder 19, and the diameter of the water inlet pipe 15 may be smaller than that of the cylinder 19, so that the inner surface of the water inlet pipe 15 may be closer to the axis of the cylinder 19 than the inner surface of the cylinder 19, thereby forming a limiting groove for limiting the lower end surface of the valve sleeve 22.

Fig. 10 is a sectional view of a second one-in-two-out valve 92 provided in the embodiment of the present application in a first state, and fig. 11 is a sectional view of the one-in-two-out valve 92 shown in fig. 10 in a second state. Referring to fig. 10 and 11, in another example, the second water passage outlet 13 and the bypass water outlet 14 are provided at different positions in the axial direction of the side wall of the cylinder 19. Fig. 10 and 11 show an example in which the second water outlet 13 is provided at the lower end of the cylinder 19 and the bypass water outlet 14 is provided at the upper end of the cylinder 19.

The valve sleeve 22 is slidably disposed in the accommodating space formed by the cylinder 19 and the cover plate 18, and the valve sleeve 22 can slide along the axial direction of the cylinder 19. The interior of the valve housing 22 may have a center hole 221, and the center hole 221 may be opposite to the first water passage port 12 of the valve body 1 and communicate with the first water passage port 12 of the valve body 1. The side wall of the valve housing 22 may have first and

second communication grooves

223 and 224 communicating with the central hole 221. The first and

second communication grooves

223 and 224 may have a predetermined interval in the axial direction of the valve housing 22. The first communicating groove 223 may be used to communicate with the second water outlet 13, and the second communicating groove 224 may be used to communicate with the bypass water outlet 14.

Additionally, the housing 22 may include a top wall and a side wall. A valve stem 21 may be attached to a top wall of the valve housing 22, and the valve stem 21 may extend through the cover plate 18 and may be movable relative to the cover plate 18 in an axial direction of the cylinder 19. The part of the valve stem 21 outside the cover plate 18 can be connected to the actuator 5. The driver 5 may be communicatively connected to the controller 7 mentioned above. The driver 5 can be linear motor, cylinder, etc. capable of outputting axial force. The driver 5 may also be a rotary motor and a conversion mechanism that converts torque into linear motion.

In another possible implementation manner of the communication groove 222, fig. 12 is a transverse cross-sectional view of a third one-in two-out valve provided in the embodiment of the present application in a first state, and fig. 13 is a transverse cross-sectional view of the one-in two-out valve shown in fig. 10 in a second state. Referring to fig. 12 and 13, at least a portion of the valve sleeve 22 may be semi-annular in cross-sectional shape. The inner surface of the valve sleeve 22 may be formed with a central bore 221 communicating with the first water passage port 12, and the valve sleeve 22 may have a circumferential first end surface 225 and a second end surface 226, that is, one circumferential end of the valve sleeve 22 may have the first end surface 225 and the other circumferential end of the valve sleeve 22 may have the second end surface 226. A communication channel 222 (not labeled in fig. 12 and 13) may also be formed between the first and second end surfaces 225, 226 of the valve sleeve 22.

Wherein a circumference of an inner surface between the second end of the second water passage port 13 of the cylinder 19 and the first end of the bypass water outlet port 14 of the cylinder 19 may be smaller than a circumference of an outer surface of the valve sleeve 22 (i.e., a circumference between the first end surface 225 of the valve sleeve 22 and the second end surface 226 of the valve sleeve 22).

Specifically, the outer surface of the valve sleeve 22 may engage the inner surface of the barrel 19 and may rotate relative to the inner surface of the barrel 19. When the valve sleeve 22 is in the first state as shown in fig. 12, the valve sleeve 22 may shield a small part of the second water through-opening 13 or not shield the second water through-opening 13, that is, a projection of the valve sleeve 22 on the cylinder 19 along the radial direction of the cylinder 19 does not fall into the second water through-opening 13 or only falls into the second water through-opening 13 a small part, so that the opening degree of the second water through-opening 13 is larger; the valve sleeve 22 may block at least part of the bypass outlet 14 so that the bypass outlet 14 is less open.

When the valve sleeve 22 is in the second state as shown in fig. 13, the valve sleeve 22 can block at least part of the second water through opening 13, that is, a projection of the valve sleeve 22 on the cylinder 19 along the radial direction of the cylinder 19 at least partially falls in the second water through opening 13, so that the opening degree of the second water through opening 13 is smaller; the valve sleeve 22 may block a small part of the bypass water outlet 14 or not block the bypass water outlet 14, that is, a projection of the valve sleeve 22 on the cylinder 19 along a radial direction of the cylinder 19 does not fall into the bypass water outlet 14 or falls into the bypass water outlet 14 only a small part, so that an opening degree of the bypass water outlet 14 is large.

The following describes a one in two out valve with the ability to vary three ports with reference to fig. 14-28, and the use of a one in two out valve with the ability to vary three ports may have the advantage of varying a wide range of flow rates with a small range of actuation.

The same point of the above-provided one in two out valve capable of changing two openings and the below-provided one in two out valve capable of changing three openings can be that: the valve core assembly 2 may include a valve sleeve 22, and the valve sleeve 22 may change the opening degrees of the second water outlet 13 and the bypass water outlet 14 by rotating in the cylinder 19. The difference lies in that: the valve core assembly 2 can further comprise a valve rod 21, and the valve rod 21 can pass through the first water through port 12 of the valve body 1 and can change the opening degree of the first water through port 12 of the valve body 1 in a sliding mode along the axis of the cylinder 19.

Fig. 19 is a longitudinal sectional view of the one-in-two-out valve 92 shown in fig. 14 in a first state, and fig. 21 is a longitudinal sectional view of the one-in-two-out valve 92 shown in fig. 14 in a second state. Referring to fig. 19 and 21, the valve stem 21 may be inserted through the cylinder 19 in an axial direction of the cylinder 19. Part of the valve stem 21 may be located outside the cover plate 18 for connection with the actuator 5; a part of the stem 21 may be located in the cylinder 19 and pass through the first water passage opening 12 of the valve body 1, and a flow passage for liquid to flow through may be formed between an outer surface of the part of the stem 21 and an inner surface of the first water passage opening 12 of the valve body 1. The size of the flow path may be varied during axial movement of the valve stem 21 along the barrel 19.

For example, in fig. 19 and 21, the valve stem 21 may be fixed with the interception plate 24, and the inner surface of the first water passage port 12 of the valve body 1 may be fixed with the water blocking table 32 in a ring shape, that is, the inside of the water blocking table 32 may have the central hole 221. During the change of the valve stem 21 from the first state to the second state, the flow passage decreases as the valve body 1 moves downward. To achieve this trend, at least one of the outer surface of the interceptor plate 24 and the inner surface of the water dam 32 has a slope. In one example, referring to fig. 19 and 21, the central hole 221 of the water blocking platform 32 may include a reverse tapered section, and a diameter of the reverse tapered section may be gradually reduced in a direction approaching an end surface of the first water passage port 12 of the valve body 1 (i.e., a lower end surface of the cylindrical body 19 in fig. 19 and 21), so that a distance between the interception plate 24 and the central hole 221 is gradually reduced in a process of gradually approaching the end surface of the first water passage port 12 of the valve body 1. Alternatively, the center hole 221 may further include a cylindrical section that may be closer to the end surface of the first water passage port 12 of the valve body 1 than the reverse taper section, and the diameter of the cylindrical section may be equal to the minimum diameter of the reverse taper section. In the second condition, part of the interceptor plate 24 may be located within the cylindrical section so as to extend the length of the smaller flow channels.

In another example, the interception plate 24 may be coaxial with the stem 21, and at least a part of the interception plate 24 may be gradually reduced in diameter in a direction close to the end surface of the first water passage port 12 of the valve body 1. In the first position, the smaller diameter end of the interceptor plate 24 may be located within the central aperture 221 of the water deflector platform 32. In the transition from the first state to the second state, the larger diameter end of the interceptor plate 24 gradually falls into the central hole 221 of the water deflector 32, so as to gradually reduce the distance between the interceptor plate 24 and the central hole 221 of the water deflector 32.

Fig. 22 is a transverse sectional view of the mounting plate 31 shown in fig. 21, and referring to fig. 21 and 22, in order to stably move the valve stem 21 relative to the valve body 1, optionally, the mounting plate 31 may be further fixed in the first water passage port 12 of the valve body 1, the mounting plate 31 may have a stopper hole for passing the valve stem 21 therethrough, and a part of the valve stem 21 may be slidably disposed in the stopper hole. In addition, a flow passage for liquid to flow through may be provided between the mounting plate 31 and the barrel 19 or the water stop 32.

To simplify the control, an actuator 5 can be used to both displace the valve stem 21 and rotate the valve sleeve 22. Referring to fig. 19 and 21, the valve stem 21 may alternatively include a first end and a second end, and the first end of the valve stem 21 may be threadedly coupled to the valve body 1, so that when the driver 5 drives the valve stem 21 to rotate, the valve stem 21 may rotate along the axial direction of the valve stem 21. A second end of the valve stem 21 may be connected to the valve sleeve 22 so that movement of the valve stem 21 causes rotation of the valve sleeve 22. Of course, in order to facilitate the change of the first water passage port 12 of the valve body 1 by the stem 21, the second end of the stem 21 may penetrate the sleeve 22 and may penetrate the first water passage port 12 of the valve body 1.

In addition, in order to make the diameter of the valve stem 21 smaller than that of the cylinder 19, the valve housing 22 is conveniently arranged. Optionally, the sleeve 4 may be accommodated in an accommodating space formed by the cylinder 19 and the cover plate 18. The sleeve 4 may include a mounting portion 41. The outer surface of the mounting portion 41 may be fixed to the inner surface of the cylinder 19, and the interior of the mounting portion 41 may have a threaded hole that is threadedly coupled to the first end of the valve stem 21. In order to avoid the liquid in the accommodating space from leaking, a sealing ring 8 may be provided between the mounting portion 41 and the inner surface of the cylinder 19. In addition, in order to facilitate the rotation of the valve sleeve 22 in the cylinder 19, referring to fig. 19 and 21, the shaft sleeve 4 may further include a stopper portion 42, the stopper portion 42 may be disposed coaxially with the mounting portion 41, and the stopper portion 42 may be located below the mounting portion 41. The diameter of the stopper portion 42 may be smaller than that of the mounting portion 41 so that a certain distance may be provided between the stopper portion 42 and the inner surface of the cylinder 19. The valve sleeve 22 can be accommodated within this spacing. That is, the valve sleeve 22 may be sleeved outside the limiting portion 42 and may be embedded inside the cylinder 19 so as to limit the radial displacement of the valve sleeve 22.

In addition, the valve rod 21 drives the valve sleeve 22 to move in the following ways:

in one of the possible implementations, the valve sleeve 22 is movable relative to the valve stem 21 as shown in fig. 15-21. Referring to fig. 15 to 21, the sidewall of the valve stem 21 may be fixed with a mounting rod 23, and the mounting rod 23 may be disposed in a radial direction of the valve stem 21. The side wall of the valve housing 22 may have a mounting groove 227 that mates with the mounting rod 23. Since the valve stem 21 moves while rotating, the mounting groove 227 is approximately L-shaped, and the mounting groove 227 may have an opening at one end.

During the rotation of the valve stem 21 with the valve sleeve 22 via the mounting rod 23 and the mounting groove 227, the valve stem 21 can have a first position as shown in fig. 15 and a second position as shown in fig. 17. Referring to fig. 16, the mounting groove 227 may include a first section 2271 and a second section 2272, the first section 2271 may extend in the axial direction of the valve housing 22, the second section 2272 may have a circumferential extension along the valve housing 22, and an end of the second section 2272 facing away from the first section 2271 is open.

Referring to fig. 19, in the first state, the second water passage opening 13 is at a large opening degree, the bypass water outlet 14 is at a small opening degree, and the first water passage opening 12 of the valve body 1 is at a large opening degree. During the process of moving the valve rod 21 from fig. 19 to fig. 21, the valve rod 21 can be lowered while rotating clockwise, and the mounting rod 23 is first in the first position shown in fig. 15, so that the valve rod 21 can drive the valve sleeve 22 to be lowered while rotating, so as to form the opening degree of the bypass water outlet 14 shown in fig. 20 and 21. When the lower end surface of the valve housing 22 abuts against the stopper 42 in the valve body 1, the mounting rod 23 can be rotated clockwise from the first position shown in fig. 15, and slid out of the mounting groove 227 from the opening of the second portion 2272 of the mounting groove 227. After the mounting bar 23 has been moved from the second position shown in fig. 17 to the first position shown in fig. 15 to form the position of the interceptor plate 24 shown in fig. 20.

Similarly, during rotation of the valve stem 21 from fig. 21 to fig. 19, the valve stem 21 may be raised while rotating counterclockwise and cause the mounting rod 23 to move from the second position shown in fig. 17 to the first position shown in fig. 15. After the mounting rod 23 moves to the first position, the valve rod 21 continues to rotate counterclockwise, so as to drive the valve sleeve 22 to rotate counterclockwise and rise, so as to form the opening degree of the bypass water outlet 14 shown in fig. 18 and 19.

It should be noted that the above-mentioned limiting portion 42 can limit the lowest position of the rotation of the valve sleeve 22, so that the limiting portion 42 supports the valve sleeve 22 when the mounting rod 23 is disengaged from the mounting groove 227 of the valve sleeve 22. In fig. 19 and 21, the upper end surface of the water stop 32 may be higher than the second water passing port 13 to support the valve sleeve 22.

In another possible implementation of the valve stem 21 to move the valve sleeve 22, the valve sleeve 22 may be fixed to the valve stem 21 as shown in fig. 23-28. The second end of the valve stem 21 may pass through the valve housing 22 and may be fixed with the valve housing 22. The valve rod 21 and the valve sleeve 22 can be fixed by non-detachable connection such as welding, bonding and the like, or detachable connection such as clamping connection, threaded connection and the like. Illustratively, in fig. 23 and 24, the side wall of the valve sleeve 22 may be provided with a mounting groove 227, and the mounting groove 227 may have a downwardly facing opening. The side wall of the valve stem 21 may be fixed with a mounting rod 23, and the mounting rod 23 may be snap-coupled with the mounting groove 227. For stable connection between the valve stem 21 and the valve housing 22, the mounting rods 23 may have at least two, and a plurality of mounting rods 23 may be uniformly distributed on the outer circumference of the valve stem 21. Fig. 23 and 24 illustrate two mounting rods 23 as an example.

It should be noted that the valve sleeve 22 is arranged in the manner described above with reference to the arrangement of the valve sleeve 22. That is, the interior of the valve housing 22 may have a central hole 221, and the side wall of the valve housing 22 may be provided with a communication groove 222 communicating with the central hole 221. The difference from the above valve housing 22 of the one-inlet two-outlet valve in which the opening degrees of the two openings are changed is that the mounting groove 227 of the side wall of the valve housing 22 shown in fig. 15 to 21 needs to be provided with an opening, so that the cross-sectional shape of the side wall of the valve housing 22 needs to be semi-circular, i.e., the circumference of the inner surface between the second end of the second water outlet 13 of the cylinder 19 and the first end of the bypass water outlet 14 of the cylinder 19 may be smaller than the circumference of the outer surface of the valve housing 22 (i.e., the circumference between the first end surface 225 of the valve housing 22 and the second end surface 226 of the valve housing 22). Further, referring to fig. 18 and 19, in the first state, the mounting groove 227 may serve as the communication groove 222 communicating with the bypass water outlet 14. In addition, since the lower end surface of the bypass water outlet port shown in fig. 23 to 28 is higher than the upper end surface of the second water outlet port, the valve sleeve has two communication grooves provided in the axial direction of the valve sleeve, as shown in fig. 24, 26, and 28. The communicating groove positioned above can be used for communicating the bypass water outlet, and the communicating groove positioned below can be used for communicating the second water outlet.

It is to be noted that the hollow arrows shown in fig. 19, 21, 26, and 28 indicate the flow direction of the liquid. Fig. 19, 21, 26 and 28 show an example in which the second water passage port 13 may be a first water passage port of a one-inlet two-outlet valve, the first water passage port 12 of the valve body 1 may be a second water passage port of a one-inlet two-outlet valve, and the bypass water outlet port 14 may be a bypass water outlet port of a one-inlet two-outlet valve. Of course, the second water passage opening 13 may also be a second water passage opening of a one-inlet two-outlet valve, the bypass water outlet 14 may also be a bypass water outlet of a one-inlet two-outlet valve, and the first water passage opening 12 of the valve body 1 may be a first water passage opening of a one-inlet two-outlet valve.

It should be noted that the above-mentioned structure of the one-inlet-two-outlet valve may also be in a third state, and the third state may be a state between the first state and the second state.
