Description

Technical Field

[0001] This invention belongs to the field of shower faucet technology, specifically relating to a zero-cold-water shower faucet assembly and a zero-cold-water shower faucet. Background Technology

[0002] Many people who use gas water heaters often encounter this problem: before taking a shower, they undress and wait for hot water in front of the showerhead for a period of time, ranging from 2 minutes to more than 5 minutes. This is manageable in summer, but becomes quite awkward in winter. They carefully avoid the spray while constantly testing the water temperature with their hands, turning what should be a relaxing shower into a thrilling adventure. Therefore, major water heater manufacturers have developed zero-cold-water water heaters to address this need, ensuring a continuous flow of hot water as soon as the tap is turned on.

[0003] The zero-cold-water shower faucet is installed in the bathroom. The faucet's water inlet is connected to the gas water heater through a pipe. The gas water heater heats the water, and when the shower faucet is turned on, the showerhead releases zero-cold-water water.

[0004] In existing technologies, after a zero-cold-water shower faucet is used and the water valve is closed, hot water usually remains in the longitudinal water pipe connected to the shower head. This water will not be discharged from the shower head until the next time the shower is used. Hot water often remains in this part of the water pipe, and the residual water cannot be discharged in time. In the humid and hot environment of the bathroom, bacteria can easily grow, affecting the health and safety of the user. Summary of the Invention

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1

[0039] Please see Figures 1-12 The present invention provides the following technical solutions:

[0040] A zero-cold-water shower faucet assembly and a zero-cold-water shower faucet, comprising:

[0041] A shower faucet assembly includes a housing 1, a filler block 2, a water supply channel 3, an inlet pipe 5, an outlet pipe 6, a first valve stem 10, and a first valve block 9. The filler block 2 is fixedly connected to the inner wall of the housing 1. The water supply channel 3 is formed within the filler block 2. The inlet pipe 5 is fixedly connected to one end of the housing 1 and communicates with the water supply channel 3. The first valve block 9 is rotatably connected within the water supply channel 3. The first valve stem 10 is rotatably connected to both the filler block 2 and the housing 1 and is fixedly connected to the upper end of the first valve block 9. The outlet pipe 6 is fixedly connected to the lower end of the housing 1 and communicates with the water supply channel 3.

[0042] The linkage drainage assembly includes a drainage connector 7, a drainage pipe 8, a second valve stem 12, a second valve block 13, a direct current channel 1301, and a drainage channel 1302. The drainage connector 7 is fixedly connected to the lower end of the housing 1 and to the circumferential surface of the outlet pipe 6. The second valve block 13 is rotatably connected inside the outlet pipe 6. Both the direct current channel 1301 and the drainage channel 1302 are located inside the second valve block 13. The second valve stem 12 is rotatably connected to the drainage connector 7, the housing 1, and the filler block 2. The upper end of the second valve stem 12 is fixedly connected to the lower end of the first valve block 9, and the lower end of the second valve stem 12 is fixedly connected to the upper end of the second valve block 13. The drainage pipe 8 is fixedly connected to the lower end of the drainage connector 7 and is connected to the outlet pipe 6.

[0043] In a specific embodiment of the present invention, a water supply channel 3 is provided in the filler block 2 of the shower faucet assembly. One end of the water supply channel 3 is connected to the inlet pipe 5, and the other end is connected to the outlet pipe 6, which are used for water inlet and outlet respectively. The inlet pipe 5 is connected to the gas water heater, and the outlet pipe 6 is used to install the shower pipe 601. One end of the shower pipe 601 is used to connect to the shower head. After the water is heated by the gas water heater, it is transported to this device through the inlet pipe 5 to achieve zero cold water showering. The handle 11 is used to drive the first valve block 9 to rotate to the left and right sides of the water supply channel 3 and the detection channel 4 through the first valve rod 10. While hot water is transported through the water supply channel 3, the water temperature detection component detects the temperature. The temperature of the hot water in channel 4 is detected. The hot water enters the outlet pipe 6 and is discharged through the shower pipe 601 and the shower head. When the outlet pipe 6 is rotated so that the left and right parts of the water supply channel 3 are no longer connected, the hot water is turned off. However, hot water still remains in the outlet pipe 6. During the rotation of the handle 11, the first valve block 9 is rotated through the first valve rod 10. The first valve block 9 is rotated through the second valve rod 12 to rotate the second valve block 13. The second valve block 13 rotates until the left part of the outlet pipe 6 is connected to the drain pipe 8. At this time, the hot water remaining in the left part of the outlet pipe 6 is discharged through the drain pipe 8, which prevents water from remaining in the outlet pipe 6 and the shower pipe 601 for a long time and thus prevents the growth of bacteria, protecting people's health.

[0044] Please refer to the details. Figures 1-12 The filling block 2 has a detection channel 4, which is connected to the water conveyance channel 3.

[0045] In this embodiment: detection channel 4 is connected to the water temperature detection component.

The spring 20 is fixedly connected to the lower end of the regulating disc 18, the rolling seat 19 is fixedly connected to the lower end of the spring 20, and the ball bearing 21 is rotatably connected to the rolling seat 19. The ball bearing 21 matches the multiple contact seats 22.

[0049] In this embodiment: the contact seats 22 in the temperature control component are uniformly fixedly connected to the filler block 2. Multiple contact seats 22 are connected to the PLC control module of the gas water heater. When the adjustment disc 18 is manually rotated, the adjustment disc 18 drives the spring 20, the rolling seat 19 and the ball 21 to rotate. The ball 21 slides on the surface of multiple contact seats 22. When it passes two contact seats 22 clockwise, it outputs a signal to increase the temperature. When it passes two contact seats 22 counterclockwise, it outputs a signal to decrease the temperature. The signal is transmitted to the PLC control module, which then performs the corresponding temperature increase and decrease operations. Gas water heaters are usually installed in the kitchen, and showers are usually installed in the bathroom. Adjusting the gas water heater in the kitchen from the bathroom makes it easier for people to take a shower and is more convenient to use.
