Detailed Description

In order to make the technical field better understand the technical scheme of the invention, the invention is further described in detail with reference to the attached drawings.

As shown in fig. 1-3, the present invention provides a shower faucet 10 with a cold water discharging function for controlling the water output of a shower device, and after the cold water and the hot water enter the shower faucet and are mixed, the mixed water is supplied to each shower device, such as a hand-held shower head 20, a top shower head 30 and a faucet 40 shown in fig. 1. The top of the shower faucet is a storage platform, and a panel for the user to operate is arranged on the side of the shower faucet facing the user.

The shower faucet further comprises a cold discharge water control for discharging residual cold water of the shower pipe, which comprises a control assembly, a switching valve and a cold discharge operation key 11. The switch valve is used for controlling the water channel of the shower equipment to be opened and closed, and the panel is provided with the cold water discharging operation key 11 and three control keys 12 for respectively controlling the water channels of the handheld shower head 20, the top shower 30 and the faucet 40 to be opened and closed. The control assembly is electrically connected with the switch valve and is used for controlling the switch valve to be opened and closed, namely the control assembly is triggered to open or close the switch valve through a control key 12 on the panel. The cold discharging operation key is electrically connected with the control assembly and used for sending a cold discharging water command to the control assembly so that the control assembly opens the switch valve to discharge residual cold water from the water outlet end of the shower device.

Further, the shower faucet includes a mixing valve having a cold water inlet, a hot water inlet, and a mixed water outlet in communication with the shower apparatus, the on-off valve being positionable at any location downstream of the mixed water outlet. Because the cold water is discharged from the water outlet end of the shower device, the residual cold water (from the mixed warm water outlet of the hot water supply device to the water outlet of the shower device) in the whole shower device pipeline can be discharged, and the cold discharge is very thorough.

The number of shower equipment in this application is 3, and correspondingly, the number of this ooff valve is 3, and this control assembly opens these 3 ooff valves in proper order and carries out the row cold when receiving row cold water instruction, and this ooff valve is preferably the solenoid valve. The cold discharge operation key can be a knob or a key. This shower faucet can also be connected with control assembly electricity including reminding the subassembly, reminds the subassembly, and the completion is arranged cold water after, control assembly control reminds the subassembly through sending and reminds sound or change modes such as light colour, tells the user that it has accomplished to arrange cold.

In this embodiment, after the user triggers the cold discharge action, the cold water is not discharged immediately, but the time that the user leaves the shower area is reserved, and the user can use the time to do some other preparation work before taking a shower, thereby avoiding the cold water from being showered by the user. Specifically, the control assembly is provided with a first timing unit, when the control assembly receives a cold water discharging instruction, the first timing unit starts timing, and when the accumulated time reaches the preset time t1, the control assembly opens the switch valve. In addition, the delayed cold water discharge can be realized by using an induction mode. The sensing assembly is electrically connected with the control assembly, and when the sensing assembly detects that the human body leaves the signal, the control assembly opens the switch valve to discharge cold water.

Further, the shower faucet further comprises a temperature detector for detecting the water temperature at the mixed water outlet, the temperature detector is electrically connected with the control assembly, the control assembly is provided with a third timing unit, when the control assembly determines that the water temperature detected by the temperature detector meets the requirement, the third timing unit starts timing, and when the accumulated time reaches the preset time t3, the control assembly closes the switch valve. Namely, the cold discharge flow is controlled by combining water temperature and time.

Of course, it is also possible to control only the time, and specifically, the control assembly has a second timing unit, the timing is started when the on-off valve is opened, and the control assembly closes the on-off valve when the accumulated time reaches the preset time t 2.

As shown in FIG. 2, the flow of cold water discharge of the shower faucet of the present invention is further illustrated, which comprises the following steps:

s1: the control assembly judges whether a cold water discharging instruction sent by a cold water discharging operation key is received, if so, the step S2 is carried out;

s2: the control assembly judges whether all the switch valves are in a closed state, if not, all the switch valves are closed, if so, the step S3 is directly carried out, and the setting of the step is mainly used for confirming that if the cold water discharging key is pressed again in the cold water discharging process, the cold water discharging operation is automatically cancelled;

s3: the first timing unit starts timing, when the accumulated time reaches the preset time t1, the control assembly opens a faucet switch valve (switch valve 1), the step S4 is carried out, namely, cold discharging is delayed, and the user leaves a shower area to start cold discharging after triggering cold discharging;

s4: the temperature detector detects the temperature of the mixed water, the control assembly judges whether the water temperature detected by the temperature detector meets the requirement, if not, the faucet switch valve (switch valve 1) is kept in an open state, if so, the third timing unit starts timing, and when the accumulated time reaches preset time t3, the control assembly closes the faucet switch valve (switch valve 1), opens the handheld shower switch valve (switch valve 2) and enters step S5;

s5: the third timing unit starts timing, when the accumulated time reaches the preset time t4, the control assembly closes the hand-held shower switch valve (switch valve 2), opens the top shower switch valve (switch valve 3), and the step S6 is executed;

s6: the third timing unit starts timing, and when the accumulated time reaches the preset time t5, the control component closes the top spraying switch valve (switch valve 3) to finish discharging cold water.

In the embodiment, cold water is discharged from the faucet, the handheld shower head and the top shower in sequence, and the cold water can be discharged simultaneously according to actual conditions, but not limited to the above.

The foregoing has described the principles and preferred embodiments of the present invention, and the above description of the embodiments is only provided to assist in understanding the method and its core ideas of the present invention.
