Description

Technical Field

[0001] The utility model relates to the technical field of bathrooms, in particular to a shower. Background Art

[0002] Existing showers require a lengthy pipe connection from the faucet valve to the water heater. The handheld showerhead and overhead showerhead also require a lengthy pipe connection. After a shower, residual water forms in these two pipes, which cools down completely over time. The next time a user turns on the shower, they have to wait for the remaining cold water to drain before hot water can be used. Furthermore, they have to determine the appropriate water temperature, which is time-consuming and laborious. This is especially detrimental to the showering experience in winter.

[0003] Although there are shower heads that can pre-drain cold water in the prior art, they are usually provided with an independent pre-drain outlet on the valve body, and are usually set to discharge water under the faucet, resulting in residual cold water in the water path behind the faucet valve of the overhead shower head and / or hand shower, and incomplete pre-drainage, which affects the user experience.

[0027] Example

[0028] Combine Figures 1 to 7As shown, this embodiment provides a shower, including a valve body 1 having a mixed water outlet channel 6, the valve body 1 is provided with at least one water outlet for connecting to a water outlet device, and a control valve 8 for controlling the connection between the water outlet and the mixed water outlet channel 6; the valve body 1 is also provided with at least one pre-drainage channel 21, which connects the water outlet and the mixed water outlet channel 6; the pre-drainage channel 21 is also provided with an electric control valve 10 for controlling the connection between the water outlet and the mixed water outlet channel 6.

[0029] The pre-drainage channel 21 is provided to connect the water outlet of the water outlet device and the mixed water outlet channel 6; and the electric control valve 10 is used to control the water outlet and the mixed water outlet channel 6 to be connected or closed through the pre-drainage channel 21; that is, during normal water discharge, water flows from the water heater through the pipeline into the valve body 1, then flows out from the mixed water outlet channel 6, flows into the water outlet through the control valve 8, and then flows out from the water outlet device; and when pre-drainage is required, the opening of the electric control valve 10 is controlled by a remote control or an intelligent device. At this time, water flows from the water heater through the pipeline into the valve body 1, then flows out from the mixed water outlet channel 6, enters the water outlet through the pre-drainage channel 21, and then flows out from the water outlet device; in this way, all the cold water originally remaining in the water path between the water heater and the valve body 1 and between the valve body 1 and the water outlet device can be directly discharged from the water outlet device.

[0030] In this embodiment, a shower head with an overhead shower head and a hand shower head is taken as an example for detailed description.

[0031] In this embodiment, if Figures 1 to 5As shown, one end of the valve body 1 is provided with a first valve chamber 2, which is equipped with a thermostatic valve 3 for regulating the temperature of the mixed water. The valve body 1 is provided with a cold water inlet connector 4 and a hot water inlet connector 5, which are connected to the first valve chamber 2. The valve body 1 is positioned outside the mixed water outlet channel 6 and is provided with three second valve chambers 7, two of which are respectively used to install the control valves 8 that control the overhead shower and handheld shower. The valve body 1 is positioned inside the mixed water outlet channel 6 and is provided with two third valve chambers 9, which are respectively used to install the electric control valves 10 that control the connection between the outlets of the overhead shower and handheld shower and the mixed water outlet channel 6. The third valve chambers 9 connect the mixed water outlet channel 6 with the pre-drain channel 21. Water can flow out of the mixed water outlet channel 6, through the control valve 8 that controls the handheld shower or overhead shower, into the corresponding outlet, and then out of the handheld shower or overhead shower. When one of the electric control valves 10 is opened, water can flow out of the mixed water outlet channel 6, through the electric control valve 10, and out of the hand shower or the overhead shower via the corresponding pre-drain channel 21. Of course, the two electric control valves 10 can be opened simultaneously, and the cold water in the pipeline can flow out of the hand shower and the overhead shower together, accelerating drainage.

[0032] In this embodiment, the electric control valve 10 is a solenoid valve, a motor-operated on / off valve, or an electric on / off valve, which can be connected to a remote control or controlled by a smart device. In this embodiment, the valve body 1 is disposed on the mixed water outlet channel 6 and is provided with a first mounting port 11. The first mounting port 11 is provided with a temperature sensor 12, which is electrically connected to the electric control valve 10. When the temperature of the water flowing in the mixed water outlet channel 6 reaches a set temperature, the temperature sensor 12 sends an electrical signal to the electric control valve 10 to close the electric control valve 10 to complete pre-drainage.

[0033] Furthermore, in this embodiment, the valve body 1 is positioned on the pre-drainage flow channel 21 and further includes a second mounting port 13 downstream of the electric control valve 10, which is equipped with a check valve 14. A sealing plug 15 is provided on the second mounting port 13 to secure the check valve 14. The provision of the check valve 14 prevents water pressure from impacting the electric control valve 10 when the control valves 8 for the overhead showerhead and hand shower are opened to discharge water. In particular, when a solenoid valve is used, the check valve 14 effectively prevents water pressure from impacting the solenoid valve's diaphragm, potentially affecting its performance and service life.

[0034] In this embodiment, since there are many flow channels in the valve body 1, such as Figure 6 and Figure 7As shown, in order to make the valve body 1 better molded, one of its water inlet connectors is integrally molded on the valve body 1; the other water inlet connector is set in an independent molding setting, and is connected to the first valve cavity 2 through a water inlet hose 16. Of course, the independently molded water inlet connector can be a hot water inlet connector 5 or a cold water inlet connector 4. In this embodiment, the hot water inlet connector 5 is molded separately as an example. The cold water inlet connector 4 is integrally molded on the valve body 1, and a cold water inlet channel is provided to communicate with the first valve cavity 2; a hot water interface 19 is also provided on the first valve cavity 2, which is connected to the hot water inlet connector 5 through a hose 16. A water outlet socket 17 is provided on one of the second valve cavities 7; the water outlet socket 17 is sealed and plugged with a top spray water outlet connector 18, which is used to connect a top spray shower. The connection port 20 of the handheld shower is integrally molded on the valve body 1.

[0035] The valve body 1 is also provided with a mounting hole 22 for mounting the valve body 1 on the housing. The last second valve cavity 7 on the valve body can be used to control the connection of other water outlet devices, such as a conventional water outlet faucet or a spray gun.
