Intelligent water-saving tap

Abstract

The invention relates to an intelligent water-saving tap for hot water. The intelligent water-saving tap comprises two parts, namely, a water tap and a controller, wherein one end of the controller is communicated with a hot water pipe while the other end of the controller is communicated with a circulating pipe; the hot water pipe and the circulating pipe are respectively communicated with a water heater; a hot water outlet communicated with the water tap is formed in a joint at which the hot water pipe is connected with the controller; the controller comprises a solenoid valve, a temperature sensor, a water pump and an electrical control box, and the solenoid valve is arranged in a joint at which the hot water outlet is connected with the hot water pipe; the temperature sensor is arranged at the upstream of the solenoid valve on the hot water pipe; the water pump is arranged between the hot water pipe and the circulating pipe; the electrical control box is used for controlling the water pump and the solenoid valve; and a signal of the temperature sensor is linked to the electrical control box. By adopting the water-saving tap provided by the invention, waste of a water resource caused by discharging certain amount of cold water before the hot water reaches the hot water outlet during a hot water using process can be avoided, so that a good water saving effect can be realized, and a user can feel comfortable during using.

Description

technical field [0001] The invention relates to an intelligent water-saving faucet used in places where hot water is used. Background technique [0002] Usually household water heaters have a certain distance to water taps, and generally a section of cold water must be let off when using hot water, which will cause waste of water resources. For example, assuming that ordinary households use water 20 times a day on average, the average water discharge time is 1.5 minutes each time, and the flow rate of the faucet is calculated at 0.20 liters per second, the amount of water wasted per day is: 0.2х20х90=360 liters, and the amount of water wasted per year It will reach 0.36х360=129.6 tons. Especially when the water tap is far away from the hot water source, the water discharge time will be as long as 5-15 minutes, and the amount of wasted water is huge. In addition, the user naturally wants to use hot water when he turns on the hot water tap, and the cold water that is release...

Problems solved by technology

Especially when the faucet is far away from the hot water source, the water discharge time will be as long as 5-15 minutes, which will waste a huge amount of water

In addition, users naturally want to use hot water when they turn on the hot water faucet, and the cold water that is released at the beginning will also make users feel very uncomfortable.
