Description

TECHNICAL FIELD

[0001] The present application relates to the field of shower, in particular to a water outlet device and a shower. BACKGROUND

[0002] The shower system comprises a shower. The shower, also known as shower head or shower nozzle, is one of the indispensable devices in modern bathroom. The shower comprises 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, and the temperature regulating valve is provided with a cold water end, a hot water end and a water outlet end. The cold water end and the hot water end of the temperature regulating valve are respectively communicated with the cold water channel and the hot water channel, and the water outlet end of the temperature regulating valve is communicated with the water outlet channel. The temperature regulating valve can adjust the proportion of the cold water entering the cold water end and the cold water entering the hot water end and mix them to be discharged to the water outlet channel through the water outlet end. The shower is communicated with the hot water end of the water heater through a pipeline. During showering, the water heater delivers hot water to the hot water channel of the shower through the pipeline, and then mixes the hot water of the hot water channel with the cold water of the cold water channel and outputs them to the water outlet channel. After bathing, a section of hot water will be left in the pipeline, which will gradually cool down to form residual cold water. When the next bathing is needed, the residual cold water in the hot water pipeline needs to be discharged before hot water can enter the hot water channel, which causes waste of water resources. In the prior art, a water storage device and a pump are provided to discharge the residual cold water in the hot water channel to the water storage device, and then the pump is used to discharge the residual cold water in the water storage device to the water outlet end. This method needs to consume additional energy to drive the pump to discharge the residual cold water in the water storage device to the water outlet end. CONTENT OF THE UTILITY MODEL

[0009] The fifth technical solution is based on the third technical solution, wherein the drain pipe extends from the inner wall of the bottom of the water storage device to the second connecting pipe in the negative direction of the Z axis.

[0010] The sixth technical solution is based on the third technical solution, wherein the drain pipe extends from the inner wall of the bottom of the water storage device to the second connecting pipe in the positive direction of the Z axis.

[0011] The seventh technical solution is based on the fifth or sixth technical solution, wherein the switch valve is provided with a valve rod, and the valve rod slides relative to the water storage tank to open and close the water storage tank.

[0012] The eighth technical solution is based on the seventh technical solution, wherein the switch valve is provided with a temperature control assembly, and the temperature control assembly is adapted to push the valve rod to slide relative to the water storage tank to close the water storage tank when the temperature rises to a first threshold value.

[0013] The ninth technical solution is based on the eighth technical solution, wherein the temperature control assembly comprises a temperature sensing element and a fixing element, the temperature sensing element is arranged in the fixing element, the fixing element is fixedly connected to the switch valve, and the temperature sensing element abuts against the valve rod and pushes the valve rod to slide when the temperature rises to the first threshold value.

[0014] The tenth technical solution relates to a shower for connecting with a water storage device, comprising a body, a temperature regulating valve and a switch valve; the body is provided with a cold water channel, a hot water channel and an outlet channel, the cold water end and the hot water end of the temperature regulating valve are connected to the cold water channel and the hot water channel respectively, and the outlet end of the temperature regulating valve is connected to the outlet channel; the water inlet of the switch valve is connected to the hot water channel, the water outlet of the switch valve is adapted to be connected to the water storage device, the water storage device is located above the cold water end, the water storage device comprises a drain pipe, one end of the drain pipe is connected to the water storage device and the other end is connected to the cold water end.

[0015] Compared with the prior art, the above-mentioned solutions have the following beneficial effects:

[0016] In the first technical solution, the water storage element is arranged above the cold water end, the water storage element is communicated with the hot water channel through the on-off valve to collect the residual cold water of the hot water channel, and then the on-off valve is closed and the temperature regulating valve is opened. At this time, the cold water end discharges water, and the water storage element arranged above the cold water end can discharge the water in the water storage element to the cold water end through the water self-weight, so that the cold water in the water storage element can be discharged without additional energy consumption.

[0017] In the first technical solution, the residual cold water is discharged to the cold water end instead of the water outlet end, so that the residual cold water is fully mixed with the hot water discharged from the hot water end and the cold water discharged from the cold water end in the temperature regulating valve, and then is discharged to the water outlet channel through the water outlet end. Compared with directly discharging the residual cold water to the water outlet end, the experience can be improved by avoiding the residual cold water not being mixed with the hot water and the cold water.

[0018] In the second technical solution, the cold water channel is provided with a Venturi tube, and the water storage element is communicated with the Venturi tube through the drain pipe. According to the Venturi effect, when the water with large flow rate of the cold water end passes through the Venturi tube, the pressure in the tube is reduced, and the water in the water storage element is sucked to the cold water end of the temperature regulating valve. When the temperature regulating valve is opened, the cold water channel discharges water, and the Venturi tube sucks the water in the water storage element to the cold water end of the temperature regulating valve. Compared with directly discharging the residual cold water, water resources are saved, and the water in the water storage element does not need to be pumped out by a pump, so that energy is saved.

[0019] In the third technical solution, the shower includes a body, a temperature regulating valve and an on-off valve. The temperature regulating valve and the on-off valve are arranged on the shower, so that the user can conveniently open and close the on-off valve during use, and does not need to open and close the on-off valve on the water storage element.

[0020] In the fourth technical solution, the shower includes a body and a temperature regulating valve, and the water storage element is provided with an on-off valve. The on-off valve controls the opening and closing of the water storage element, and compared with the on-off valve arranged on the shower, the on-off valve is more convenient to install, use and maintain.

[0021] In the fifth technical solution, the drain pipe extends from the inner wall of the bottom of the water storage element to the second connecting pipe along the negative direction of the Z axis. At this time, the water can be discharged from the bottom of the water storage element to the cold water end according to the water self-weight, so that water resources and energy are saved.

[0022] In the sixth technical solution, the drain pipe extends from the inner wall of the bottom of the water storage element to the second connecting pipe along the positive direction of the Z axis. Since the water storage element is higher than the cold water end, according to the siphon effect, the water column pressure difference makes the water rise along the drain pipe and then flow to the cold water end, so that water resources and energy are saved.

[0023] In the seventh technical solution, when the temperature regulating valve is closed and the on-off valve is opened, the water storage element starts to collect the residual cold water. After the collection is completed, the on-off valve is closed. In order to avoid forgetting to close the on-off valve, a temperature control assembly is arranged. When the temperature rises to a first threshold value, the on-off valve is automatically closed. BRIEF DESCRIPTION OF DRAWINGS

[0038] Embodiment One

[0039] Figure 1 The water outlet device 1 in the embodiment is shown as follows, Figure 1 The water outlet device 1 includes a shower 2 and a water storage part 3. The shower 2 is connected to the water storage part 3. The water storage part 3 is arranged above the shower 2. In the embodiment, the shower 2 includes a body 4 and a temperature control valve 5. The temperature control valve 5 is arranged on the body 4. The water storage part 3 includes an on-off valve 6, a water storage tank 7, a first connecting pipe 8, a second connecting pipe 9 and a drain pipe 10. In other embodiments, the shower 2 includes the body 4, the on-off valve 6 and the temperature control valve 5. The water storage part 3 includes the water storage tank 7, the first connecting pipe 8, the second connecting pipe 9 and the drain pipe 10. The body 4 is provided with a cold water channel 11, a hot water channel 12 and a water outlet channel 13. The temperature control valve 5 is provided with a cold water end 14, a hot water end 15 and a water outlet end 16. The temperature control valve 5 is used to mix water from the hot water end 15 and the cold water end 14 and output to the water outlet end 16. The cold water end 14 and the hot water end 15 of the temperature control valve 5 are respectively connected to the cold water channel 11 and the hot water channel 12. The water outlet end 16 of the temperature control valve 5 is connected to the water outlet channel 13. The on-off valve 6 is used to control whether the water storage part 3 collects water from the hot water channel 12. The water storage tank 7 is arranged above the cold water end 14. The water storage tank 7 is connected to the hot water channel 12 through the first connecting pipe 8 and the on-off valve 6 to collect residual cold water from the hot water channel 12. The on-off valve 6 is used to open and close the water storage tank 7. The second connecting pipe 9 is used to connect the drain pipe 10 and the cold water end 14. The drain pipe 10 is used to connect the second connecting pipe 9 and the water storage part 3.

[0040] Figure 2 The shower 2 in the embodiment is shown as follows, Figure 1 and Figure 2 The second connecting pipe 9 is connected to the drain pipe 10. The drain pipe 10 extends from the inner wall of the bottom of the water storage part 3 to the second connecting pipe 9 along the negative direction of the Z axis. The hot water channel 12 is connected to the on-off valve 6 and the hot water end 15 of the temperature control valve 5. The cold water channel 11 is used to connect the cold water end 14 of the temperature control valve 5 and the second connecting pipe 9 of the water storage tank 7. The hot water channel 12 is used to input hot water. The cold water channel 11 is used to input cold water. The water outlet channel 13 is used to output total water of the shower 2.

[0041] Figure 3 The position of the Venturi tube 17 is shown as Figure 1 and Figure 3 The cold water end 14 is provided with a Venturi tube 17, one end of which is fixed to the cold water end 14 and the other end is communicated with the second connecting pipe 9. The water in the cold water channel 11 enters the cold water end 14 and mixes with the water in the hot water channel 12 through the Venturi tube 17. When the water in the outlet channel 13 is discharged, the Venturi tube 17 sucks the water in the water storage member 3 to the cold water end 14 of the temperature regulating valve 5, and then the residual cold water in the water storage member 3 mixes with the cold water in the cold water channel 14 and the hot water in the hot water channel 12.

[0042] Figure 4 The on-off valve 6 in the first embodiment is shown as Figure 4 The on-off valve 6 is fixed with a temperature control assembly 20. The on-off valve 6 includes a valve stem 18 and a valve body 19. The temperature control assembly 20 includes a fixing member 21 and a temperature sensing member 22. The valve body 19 is fixed to the shower 2. The valve stem 18 slides relative to the valve body 19 to open or close the on-off valve 6. The fixing member 21 is fixed to the valve body 19. The temperature sensing member 22 is arranged on the fixing member 21. When the temperature reaches a first threshold value, the temperature sensing member 22 expands and abuts against the valve stem 18, so that the valve stem 18 slides relative to the valve body 19 to close the on-off valve 6. When the temperature is lower than the first threshold value, the temperature sensing member 22 returns to its original shape, and the valve stem 18 remains stationary.

[0043] As shown in Figures 1 to 4As shown, before use, the switch valve 6 and the temperature regulating valve 5 are both closed, at this time, the water outlet 13 is closed, the water in the hot water channel 12 and the water in the cold water channel 11 are blocked in the water outlet end 16 of the temperature regulating valve 5. In use, first open the switch valve 6 on the shower 2, because the temperature regulating valve 5 is closed, after the switch valve 6 is opened, the residual cold water in the hot water channel 12 flows to the opened switch valve 6 through the hot water channel 12, then enters the first connecting pipe 8 and then enters the water storage tank 7. When the temperature reaches the first threshold, the temperature sensing element 22 expands and pushes the valve rod 18 to slide relative to the valve body 19, so that the switch valve 6 is closed, and the water in the hot water channel 12 cannot enter the water storage tank 7. At this time, adjust the temperature regulating valve 5, open the temperature regulating valve 5 after adjusting the temperature to the required temperature. After the temperature regulating valve 5 is opened, because the switch valve 6 is closed, the hot water in the hot water channel 12 will flow to the hot water end 15 of the temperature regulating valve 5, and the cold water in the cold water channel 11 will also flow to the cold water end 14 of the temperature regulating valve 5. At this time, the water in the water storage tank 7 is higher than the water in the cold water end 14, so the water in the water storage tank 7 can flow from the water storage tank 7 to the cold water end 14 through the drain pipe 10 and the second connecting pipe 9 according to the weight of the water. Because the cold water end 14 is provided with a Venturi tube 17, one end of the second connecting pipe 9 communicates with the end of the Venturi tube 17 away from the cold water pipe. The water in the cold water end 14 flows out through the Venturi tube 17, and the flow rate of the water in the Venturi tube 17 increases at this time. The pressure at the end of the second connecting pipe 9 communicating with the Venturi tube 17 is reduced, further increasing the flow rate of the residual cold water in the drain pipe 10 and the second connecting pipe 9. The residual cold water, the cold water in the cold water channel 11 and the hot water in the hot water channel 12 are mixed together at the temperature regulating valve 5 and then discharged to the water outlet 13 through the water outlet end 16.

[0044] In this embodiment, the water storage element 3 is arranged above the cold water end 14. After the switch valve 6 is closed and the temperature regulating valve 5 is opened, the water in the water storage element 3 can be discharged to the cold water end 14 by the weight of the water.

[0045] In this embodiment, the residual cold water is discharged to the cold water end 14 instead of the water outlet end 16, so that the residual cold water is fully mixed with the hot water flowing out of the hot water end 15 and the cold water flowing out of the cold water end 14 in the temperature regulating valve 5 before being discharged to the water outlet 13 through the water outlet end 16. Compared with directly discharging the residual cold water to the water outlet end 16, this is beneficial to avoid the experience of the user being reduced due to the residual cold water not being mixed with the hot water flowing out of the hot water end 15 and the cold water flowing out of the cold water end 14 uniformly.

[0046] In this embodiment, the cold water channel 11 is provided with a Venturi tube 17, and the water storage member 3 is connected to the Venturi tube 17 through the drain pipe 10. According to the Venturi effect, when the water with a large flow rate at the cold water end 14 passes through the Venturi tube 17, the pressure in the tube is reduced, and the residual cold water in the water storage member 3 is sucked to the cold water end 14 of the mixing valve 5. When the mixing valve 5 is opened, the water in the water storage member 3 is sucked to the cold water end 14 of the mixing valve 5 by the Venturi tube 17 when the cold water channel 11 discharges water, which is more water-saving than directly discharging the residual cold water from the water outlet channel 16, and does not need to pump the water in the water storage member 3, which is more conducive to saving energy.

[0047] In this embodiment, the shower 2 includes the body 4, the mixing valve 5, and the on-off valve 6. Before bathing, the on-off valve 6 is opened to discharge the residual cold water at the hot water end 15 to the water storage member 3, and then the on-off valve 6 is closed. The temperature of the water discharged from the water outlet end 16 is set, and the mixing valve 5 is opened. At this time, the water in the water storage member 3 is mixed with the water at the hot water end 15 and the cold water end 14, and then discharged to the water outlet end 16 of the mixing valve 5, and then discharged to the water outlet channel 13 through the water outlet end 16 of the mixing valve 5.

[0048] In this embodiment, the shower 2 includes the body 4 and the mixing valve 5. The water storage member 3 is provided with the on-off valve 6. Before bathing, the on-off valve 6 is opened to discharge the residual cold water at the hot water end 15 to the water storage member 3, and then the on-off valve 6 is closed. The temperature of the water discharged from the water outlet end 16 is set, and the mixing valve 5 is opened. At this time, the water in the water storage member 3 is mixed with the water at the hot water end 15 and the cold water end 14, and then discharged to the water outlet end 16 of the mixing valve 5, and then discharged to the water outlet channel 13 through the water outlet end 16 of the mixing valve 5.

[0049] In this embodiment, one end of the drain pipe 10 extends from the inner wall of the bottom of the water storage member 3 to the second connecting pipe 9 along the negative direction of the Z axis. At this time, the water can be discharged from the bottom of the water storage member 3 to the cold water end 14 according to the self-weight of the water, which is conducive to saving water resources and energy.

[0050] Embodiment Two

[0051] Figure 5 As shown in FIG. 2, the shower 2 of this embodiment is connected to the water storage member 3 through the second connecting pipe 9 and the drain pipe 10. Figure 5 The only difference between this embodiment and Embodiment One is that the drain pipe 10 extends from the inner wall of the bottom of the water storage member 3 to the second connecting pipe 9 along the positive direction of the Z axis. Since the position of the water storage tank 7 is higher than that of the cold water end 14, the residual cold water in the water storage tank 7 and the water in the cold water end 14 form a height difference. According to the siphon effect, this height difference can make the water flow upward along the drain pipe 10 along the Z axis and then flow to the second connecting pipe 9.

[0052] In the embodiment, the drain pipe 10 extends from the inner wall of the bottom of the water storage member 3 along the positive direction of the Z axis to the second connecting pipe 9. Since the water storage member 3 is higher than the cold water end 14, according to the siphon effect, the pressure difference of the water column in the drain pipe 10 makes the water rise along the drain pipe 10 and then flow to the cold water end 14, which is beneficial to save water resources and energy. The above description of the specification and the embodiments is used to explain the protection scope of the present application, but does not constitute a limitation on the protection scope of the present application.
