Description

Technical Field

[0001] The utility model relates to the field of sanitary equipment. More specifically, the utility model relates to a digital display shower with wireless control. Background Art

[0002] After the existing shower is used, there will inevitably be residual cold water left in the shower. When the shower is used next time, the water flowing out of the shower first is the residual cold water, which greatly reduces the user experience. Many users will choose to turn on the shower faucet before taking a shower to drain the residual cold water first, and start taking a shower after feeling the water temperature reach an appropriate temperature by hand. However, the disadvantages of this method are also very obvious. Users need to wait for the residual cold water to drain out when turning on the shower, and they need to judge whether the water temperature is appropriate by themselves, which is time-consuming and laborious, and also wastes water resources to a certain extent. Therefore, there is an urgent need for a shower that can pre-drain cold water to solve the above problems.

[0003] The utility model patent with the authorization announcement number of CN 215112049 U discloses a cold water pre-draining device applied to a shower, which includes a housing, an MCU, a solenoid valve, a hot water inlet pipe, a cold water inlet pipe, a lower outlet pipe, a mixing valve, a water distribution valve, a shower head outlet pipe, a temperature sensor and a switch. Among them, the temperature sensor is connected to the MCU and is arranged in the lower outlet pipe, and the switch is connected to the MCU and is arranged on the surface of the housing; when the MCU receives the trigger signal of the switch, it opens the solenoid valve to let the water in the hot water inlet pipe flow away from the lower outlet pipe. When the MCU detects through the temperature sensor that the water temperature is higher than the preset temperature threshold, it closes the solenoid valve to let the hot water in the hot water inlet pipe be mixed with the cold water in the cold water inlet pipe through the mixing valve, and then is conveyed to the shower head outlet pipe through the water distribution valve; the switch is a photoelectric induction switch, a magnetic induction switch, a mechanical switch or a capacitive touch switch. Although this 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 perform the cold water pre-draining operation, which is very inconvenient to operate.
