Description

Technical Field

[0001] This application relates to the field of shower devices, specifically to a water storage component, a shower device, and a water outlet device. Background Technology

[0002] A shower system includes a showerhead. A showerhead, also known as a shower shower or shower sprayer, is an indispensable piece of equipment in a modern bathroom. The showerhead consists of a main body and a thermostatic valve. The main body has cold water channels, hot water channels, and an outlet channel. The thermostatic valve has a cold water end, a hot water end, and an outlet end. The cold water and hot water ends of the thermostatic valve are connected to the cold water and hot water channels, respectively, while the outlet end is connected to the outlet channel. The thermostatic valve adjusts the ratio of cold water entering the cold water end to cold water entering the hot water end, mixing them before discharging them into the outlet channel. The showerhead connects to the hot water channel of the water heater via pipes. During showering, the water heater delivers hot water through the pipes to the hot water channel of the showerhead, mixes the hot water in the hot water channel with the cold water in the cold water channel, and then outputs it into the outlet channel. After showering, a section of hot water remains in the pipes, gradually cooling to form residual cold water. This residual cold water must be drained from the hot water pipes before hot water can enter the hot water channel for the next shower, resulting in water waste.

[0003] In the prior art, a water storage device is provided, which has a water collection channel and a switch valve. The water collection channel is suitable for connecting the water storage device and the hot water end of the shower. The switch valve is suitable for opening and closing the water collection channel. Before showering, the switch valve is opened to pre-drain the residual cold water in the hot water channel into the water storage device. After draining the residual cold water, the switch valve is closed. In the prior art, the switch valve can be automatically closed by using a solenoid valve. This type of switch valve requires energy to drive. Utility Model Content

[0004] The purpose of this application is to provide a water storage device, a shower, and a water outlet device that are conducive to energy conservation.

[0005] To achieve the above objectives, the following technical solution is adopted:

[0006] The first technical solution relates to a water storage device for collecting residual cold water from the hot water end of a shower. The water storage device includes a water tank, a switch valve, and a control component. The water tank has a water collection channel adapted to connect to the hot water end. The switch valve has a valve stem that slides relative to the water tank to open and close the water collection channel. The control component includes a rotating member and a floating member fixedly connected to each other. The rotating member rotates relative to the water tank. When the water in the water tank reaches a preset position, the floating member drives the rotating member to rotate and push against the valve stem, causing it to slide to close the water collection channel.

[0007] The second technical solution is based on the first technical solution, wherein the rotating component is provided with an abutment member that is threadedly connected to the rotating component, and the abutment member is adapted to abut against the valve stem so that it slides to close the water collection channel.

[0008] The third technical solution is based on the second technical solution, wherein the switching valve further includes a valve body, the valve body is provided with a first water passage communicating with the water collection channel and a second water passage communicating with the water storage tank, the first water passage and the second water passage are connected through a water passage hole, the valve stem is provided with a sealing member, the sealing member is adapted to abut against the water passage hole to disconnect the first water passage and the second water passage so that the water collection channel is closed.

[0009] The fourth technical solution is based on the third technical solution, wherein the first water passage and the second water passage are disposed on both sides of the water passage hole.

[0010] The fifth technical solution is based on the fourth technical solution, wherein the water flow in the valve body is adapted to flow out from the hot water channel sequentially through the first water passage, the water passage hole and the second water passage to the water storage tank, the valve stem is perpendicular to the first water passage and the sealing element is always located on the side of the water passage hole close to the first water passage.

[0011] The sixth technical solution is based on the fifth technical solution, wherein the switching valve is further provided with an elastic element, the elastic element being adapted to drive the valve stem to slide relative to the valve body so that the sealing element abuts against the water passage hole.

[0012] The seventh technical solution is based on the sixth technical solution, wherein the switching valve and the water storage tank are assembled by a spring pin assembly.

[0013] The eighth technical solution is based on the seventh technical solution, wherein the spring pin assembly includes a spring and a pin, the pin is adapted to slide on the switch valve and the water storage tank, the pin is adapted to slide completely into the switch valve, and the spring is adapted to drive the pin to slide relative to the water storage tank so that the pin abuts against the switch valve and the water storage tank respectively.

[0014] The ninth technical solution relates to a shower for connection with a water storage component as described in any one of the first to eighth technical solutions, characterized in that it includes a body and a temperature regulating valve; the body is provided with a cold water channel, a hot water channel and a water outlet channel, the cold water end and hot water end of the temperature regulating valve are respectively connected to the cold water channel and the hot water channel, and the water outlet end of the temperature regulating valve is connected to the water outlet channel; the inlet of the switch valve is connected to the hot water channel, and the outlet of the switch valve is adapted to connect to the water storage component.

[0015] The tenth technical solution relates to a water outlet device, characterized in that it includes a water storage component as described in any one of the first to eighth technical solutions and a shower as described in the ninth technical solution, wherein the water collection channel of the water storage component is connected to the hot water end of the shower.

[0016] Compared with existing technologies, the above solution has the following beneficial effects:

[0017] In existing technology, a shower unit connects the hot water channel to the hot water outlet of the water heater via a pipe. During showering, the water heater delivers hot water through the pipe to the hot water channel of the shower unit, then mixes the hot water from the hot water channel with the cold water from the cold water channel before outputting it to the outlet channel. After showering, a section of hot water remains in the pipe, gradually cooling to form residual cold water. Because the pipe length is fixed, the volume of the residual cold water is also fixed, therefore the volume of residual cold water discharged into the water storage container is also fixed, meaning the height of the residual cold water in the water storage container is fixed.

[0018] In the first technical solution, the valve stem slides relative to the water storage tank to open and close the water collection channel. The rotating part rotates relative to the water storage tank. Based on the principle that the density of the floating part is less than that of water, when the water level in the water storage device reaches a preset position, the floating part will also reach a preset position. The preset height here is the height of the residual cold water in the water storage device after all the residual cold water in the pipe has been discharged into the water storage device. At this time, the floating part drives the rotating part to rotate and push against the valve stem, causing it to slide to close the water collection channel. The switch valve is a normally closed switch valve, which is opened when in use and automatically closed after the residual cold water is collected. Compared with the solenoid valve, the switch valve is beneficial for saving energy.

[0019] In the second technical solution, the rotating component is provided with an abutment that is threadedly connected to the rotating component. The abutment is adapted to abut against the valve stem so that it slides to close the water collection channel. Since the volume of residual cold water in each household is different, in order to accommodate different volumes of residual cold water, the abutment is threadedly connected to the rotating component. By adjusting the position of the abutment in different positions of the rotating component, it is possible to control whether the abutment abuts against the valve stem at different heights of the floating component.

[0020] In the third technical solution, the switching valve includes a valve body and a valve stem with a sealing element. The sealing element is adapted to abut against the water passage to disconnect the first water passage and the second water passage. When the valve stem slides, the sealing element also slides. When the sealing element abuts against the water passage, the first water passage and the second water passage are disconnected. At this time, the water collection channel is closed and the water storage device stops collecting residual cold water.

[0021] In the fifth technical solution, the valve stem is perpendicular to the first water passage, and the sealing element is always located on the side of the water passage closer to the first water passage. When the sealing element abuts against the water passage, the water flow in the first water passage is blocked by the sealing element and cannot pass through the water passage, thus cutting off the water flow. The water storage device stops collecting residual cold water. At this time, the sealing element receives the pressure of the water flow in the first water passage, causing the valve stem to stop and keeping the water storage device in a closed state. Even if the water level in the water storage device drops at this time, the switch valve cannot be opened, which is beneficial to keep the water storage device in a closed state while saving energy.

[0022] In the sixth technical solution, the switch valve is also equipped with an elastic element, which drives the sealing element to remain in contact with the water passage hole, further maintaining the closed state of the water storage element.

[0023] In the eighth technical solution, the switch valve and the water storage tank are assembled by a spring pin assembly. The spring pin assembly, through the cooperation of the pin and the spring, makes the assembly and disassembly of the switch valve and the water storage tank more convenient, which is beneficial to the cleaning and maintenance of the water storage components.

[0039] Example

[0040] Figure 1 The water outlet device 1 in this embodiment is shown, such as Figure 1 As shown, the water outlet device 1 includes a shower head 2 and a water storage unit 3. The shower head 2 is connected to the water storage unit 3. The shower head 2 includes a body 4 and a thermostatic valve 5. The thermostatic valve 5 is installed on the body 4 and is used to open and close the water outlet 8 and adjust the water temperature of the water outlet 8. The body 4 has a cold water channel 6, a hot water channel 7, and a water outlet 8. The thermostatic valve 5 has a cold water end 9, a hot water end 10, and a water outlet end 11. The cold water end 9 of the thermostatic valve 5 is connected to the cold water channel 6 of the body 4, the hot water end 10 is connected to the hot water channel 7 of the body 4, and the water outlet end 11 is connected to the water outlet 8 of the body 4. The water storage unit 3 has a water collection channel 12, through which the water storage unit 3 collects residual cold water from the hot water channel 7. The water storage unit 3 includes a water storage tank 13, a switch valve 14, and a control component 15. The water storage tank 13 is used to collect residual cold water from the hot water channel 7. The hot water channel 7 is connected to both the water storage tank 13 and the hot water end 10. The on / off valve 14 is used to control the opening and closing of the water collection channel 12, thereby controlling the opening and closing of the water storage tank 13. The on / off valve 14 includes an inlet 16 and an outlet 17. The inlet 16 of the on / off valve 14 is connected to the hot water channel 7, and the outlet 17 of the on / off valve 14 is adapted to connect to the water storage tank 13. The control assembly 15 is adapted to control the closing of the on / off valve 14, so that the water collection channel 12 is closed.

[0041] Figure 2 and Figure 3 The switching valve 14 in this embodiment is shown, as follows: Figure 2 and Figure 3 As shown, the switching valve 14 includes a valve body 18, a valve stem 19, and an elastic element 20. The valve stem 19 slides relative to the valve body 18, and the elastic element 20 is adapted to keep the valve stem 19 sliding until the water collection channel 12 is closed. The valve body 18 is provided with a first water passage 21, a second water passage 22, and a water passage hole 23. The first water passage 21 connects to the water collection channel 12, the second water passage 22 connects to the water storage tank 13, and the first water passage 21 and the second water passage 22 are connected through the water passage hole 23. Figure 2 and Figure 3 As shown, the valve body also includes a first sealing surface 33 and a second sealing surface 34. The first sealing surface 33 is located on the water passage 23, and the second sealing surface 34 is away from the water passage 23. The first water passage 21 and the second water passage 22 are arranged on both sides of the water passage 23. The water flow in the valve body 18 is adapted to flow from the hot water passage 7 through the first water passage 21, the water passage 23, and the second water passage 22 to the water storage tank 13. A sealing element 24 is provided on the valve stem 19. The sealing element 24 is adapted to abut against the water passage 23 to disconnect the first water passage 21 and the second water passage 22 so that the water collection channel 12 is closed. The sealing element 24 is always located between the first sealing surface 33 and the second sealing surface 34. When the sealing element 24 abuts against the water passage 23, it also abuts against the first sealing surface 33. When the sealing member 24 abuts against the first sealing surface 33, the water flow cannot flow into the second water passage 22. At this time, the water collection channel 12 is disconnected. When the sealing member 24 abuts against the second sealing surface 34, the water pressure generated by the water flowing out of the first water passage 21 exerts pressure on the sealing member 24. At this time, the sealing member 24 remains in contact with the second sealing surface 34. When the sealing member 24 moves away from the second sealing surface 34, the left and right water pressures on the sealing member 24 begin to balance. Driven by the elastic member 20, the sealing member 24 will move towards the water passage 23 until it abuts against the water passage 23 and the first sealing surface 33. At this time, the switch valve 14 is closed.

[0042] Figure 4 and Figure 5 The water storage component 3 in this embodiment is shown, such as Figure 4 and Figure 5As shown, the control assembly 15 includes a rotating member 25 and a floating member 26, which are fixedly connected to each other. The rotating member 25 is rotatably connected to the water storage tank 13 and rotates relative to the water storage tank 13. The rotating member 25 is provided with an abutment member 27, which is threadedly connected to the rotating member 25. The abutment member 27 is adapted to abut against the valve stem 19, causing it to slide until the sealing member 24 abuts against the water passage 23, thereby disconnecting the first water passage 21 and the second water passage 22 and closing the water storage tank 13. The floating member 26 is adapted to float on the residual cold water in the water storage tank 13. When the residual cold water in the water storage tank 13 reaches a preset position, the floating member 26 also reaches a preset position. At this time, the floating member 26 drives the rotating member 25 to rotate, causing the abutment member 27 to abut against the valve stem 19. Then, the valve stem 19 is pushed by the abutment member 27 and slides relative to the valve body 18, thereby closing the water collection channel 12. Since the volume of residual cold water varies from household to household, in order to accommodate different volumes of residual cold water, the position of the abutment 27 relative to the adapter can be adjusted to control whether the abutment 27 and the valve stem 19 abut against each other at different heights of the floating part 26.

[0043] Before using the shower 2, the switch valve 14 can be opened. At this time, the first water passage 21 and the second water passage 22 are connected, and the water collection channel 12 is opened, which opens the water storage tank 13. The residual cold water in the hot water passage 7 can flow into the water storage tank 13 through the water collection channel 12, the first water passage 21, the water passage hole 23, and the second water passage 22. At this time, the water level in the water storage tank 13 begins to rise. After a period of time, most of the residual cold water in the hot water passage 7 is discharged into the water storage tank 13. At this time, the water level in the water storage tank 13 reaches the preset position, and the floating part 26 also begins to rise with the water level to the preset position. At this time, the abutment part 27 just abuts the valve stem 19. At this time, the residual cold water in the hot water passage 7 continues to be discharged into the water storage tank 13 through the water collection channel 12. After the water level reaches the preset position, it continues to rise. At this time, the floating part 26 rises with the water level. The floating component 26 continues to drive the rotating component 25 to rotate, and the abutting component 27 rotates with the rotating component 25. The abutting component 27 pushes the valve stem 19 to move relative to the valve body 18. When all the residual cold water in the hot water channel 7 is drained, the abutting component 27 pushes the valve stem 19 to the position where the sealing component 24 abuts against the water passage 23. At this time, the switch valve 14 is closed, the first water passage 21 and the second water passage 22 are disconnected, the water collection channel 12 is closed, and the water storage tank 13 stops collecting water from the hot water channel 7.

[0044] Figure 6 The spring-loaded component in this embodiment is shown, such as Figure 6As shown, the switch valve 14 is mounted on the water storage tank 13 via a spring-loaded assembly 32. The spring-loaded assembly 32 includes a pin 28 and a spring 29. The pin 28 is adapted to slide on both the switch valve 14 and the water storage tank 13, and is adapted to slide fully into the switch valve 14. The spring 29 is adapted to drive the pin 28 to slide relative to the water storage tank 13 so that the pin 28 abuts against both the switch valve 14 and the water storage tank 13. When the switch valve 14 needs to be installed, the pin 28 is squeezed, at which point the spring 29 is compressed. The switch valve 14 is then inserted into the water storage tank 13, at which point the spring 29 squeezes the pin 28, and the end of the pin 28 away from the spring 29 abuts against the water storage tank 13. When the pin 28 reaches the slot 30 of the water storage tank, the pin 28 springs into the slot 30, thus completing the installation of the switch valve 14. When the switch valve 14 needs to be removed, the pin 28 needs to be pressed so that it slides fully into the groove 31 of the switch valve 14, at which point the switch valve 14 can be pulled out.

[0045] In this embodiment, the valve stem 19 slides relative to the water storage tank 13 to open and close the water collection channel 12. The rotating part 25 rotates relative to the water storage tank 13. Based on the principle that the density of the floating part 26 is less than that of water, when the water level in the water storage device 3 reaches a preset position, the floating part 26 will also reach a preset position. The preset height here is the height of the residual cold water in the water storage device 3 after all the residual cold water in the pipe is discharged into the water storage device 3. At this time, the floating part 26 drives the rotating part 25 to rotate and push against the valve stem 19 to make it slide to close the water collection channel 12. The switch valve 14 is a normally closed switch valve 14. It is opened when in use and automatically closed after the residual cold water is collected. Compared with the solenoid valve, the switch valve 14 is more energy-efficient.

[0046] In this embodiment, the rotating member 25 is provided with an abutment member 27 threadedly connected to the rotating member 25. The abutment member 27 is adapted to abut against the valve stem 19 so that it slides to close the water collection channel 12. Since the volume of residual cold water in each household is different, in order to accommodate different volumes of residual cold water, the abutment member 27 is threadedly connected to the rotating member 25. By adjusting the abutment member 27 at different positions of the rotating member, it is possible to control whether the abutment member 27 abuts against the valve stem 19 at different heights of the floating member 26.

[0047] In this embodiment, the switching valve 14 includes a valve body 18 and a valve stem 19 is provided with a sealing member 24. The sealing member 24 is adapted to abut against the water passage 23 to disconnect the first water passage 21 and the second water passage 22. When the valve stem 19 slides, the sealing member 24 also slides. When the sealing member 24 abuts against the water passage 23, the first water passage 21 and the second water passage 22 are disconnected. At this time, the water collection channel 12 is closed, and the water storage device 3 stops collecting residual cold water.

[0048] In this embodiment, the valve stem 19 is perpendicular to the first water passage 21 and the sealing member 24 is always located on the side of the water passage close to the first water passage 21. When the sealing member 24 abuts against the water passage 23, the water flow in the first water passage 21 is blocked by the sealing member 24 and cannot pass through the water passage 23, thus cutting off the water flow. The water storage device 3 stops collecting residual cold water. At this time, the sealing member 24 receives the pressure of the water flow in the first water passage 21, causing the valve stem 19 to stop and keeping the water storage device 3 in a closed state. Even if the water level in the water storage device 3 drops at this time, the switch valve 14 cannot be opened, which is beneficial to keep the water storage device 3 in a closed state while saving energy.

[0049] In this embodiment, the switching valve 14 is also provided with an elastic element 20, which drives the sealing element 24 to remain in contact with the water passage 23, thereby further maintaining the closed state of the water storage element 3.

[0050] The above description of the specification and embodiments is used to explain the scope of protection of the present application, but does not constitute a limitation on the scope of protection of the present application.
