Description

Technical Field

[0001] The present invention relates to the field of bathroom equipment, and more specifically, to a wirelessly controlled digital display shower. Background Art

[0002] After using the existing shower, it is inevitable that there will be residual cold water left in the shower. The first water that flows out of the shower next time is the residual cold water, which greatly reduces the user experience. Many users will choose to open the shower faucet before taking a shower to drain the residual cold water, and then start showering after feeling the water temperature with their hands to reach the appropriate temperature. However, the disadvantages of this method are also very obvious. The user needs to wait for the residual cold water to drain out before turning on the shower, and the user needs to judge whether the water temperature is appropriate, which is time-consuming and laborious, and also wastes water resources to a certain extent. Therefore, a shower that can pre-drain cold water is urgently needed to solve the above problems.

[0003] The utility model patent with the authorization announcement number CN 215112049 U discloses a pre-drain cold water device for a shower, which includes a housing, an MCU, a solenoid valve, a hot water inlet pipe, a cold water inlet pipe, a lower water outlet pipe, a mixing valve, a water diverter valve, a shower outlet pipe, a temperature sensor and a switch, wherein the temperature sensor is connected to the MCU and arranged in the lower water outlet pipe, and the switch is connected to the MCU and arranged on the surface of the housing; when the MCU receives a trigger signal from the switch, the solenoid valve is opened to allow the water in the hot water inlet pipe to flow out of the lower water outlet pipe; when the MCU detects that the water temperature is higher than a preset temperature threshold through the temperature sensor, the solenoid valve is closed to allow the hot water in the hot water inlet pipe and the cold water in the cold water inlet pipe to mix through the mixing valve and then be transported to the shower outlet pipe through the water diverter valve; the switch is a photoelectric induction switch, a magnetic induction switch, a mechanical switch or a capacitive touch switch. Although the patent can pre-drain cold water through switch control, the switch is arranged on the housing, and the user needs to walk to the shower to turn on the switch to pre-drain cold water, which is very inconvenient.
