Problems solved by technology

However, such a hot water circulation system needs to add solenoid valves and water pumps to the water pipes, and needs to install a controller to control the temperature sensor, so the cost of the water circulation return device is relatively high, the structure is complicated, and the cost of transforming the pipeline is relatively high and the procedure is also difficult. It is more complicated, and the circulating water return device

Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] Circulating faucet 1 of the present invention, as Figure 1-4 As shown, it includes a cold water inlet pipe 2, a hot water inlet pipe 3, a faucet switch 4, and an on-off valve 5 between the faucet switch 4 and the water outlet 6, that is, an additional on-off valve 5 is installed on the ordinary faucet 1. , figure 1 The middle on-off valve 5 has not yet been loaded into the water tap 1. The on-off valve 5 can be a ball valve, such as figure 2 As shown, there is a spool 7 inside which is in the shape of a ball, and there is a water pipe 71 inside the spool 7. The toggle end 8 of the spool 7 is exposed to the on-off valve 5 to control the closing and opening of the on-off valve 5. As long as the toggle end 8 is turned to rotate the ball valve 7 to communicate with the water passage in the water pipe 71 and the faucet 1, the on-off val...

Abstract

The invention discloses a circulating water tap, comprising a water tap switch, a water outlet, a hot water feeding pipe and a cold water feeding pipe; a switch valve is mounted between the water tap switch and the water outlet. The hot water circulating system having the circulating water tap comprises: a water heater, a hot water pipe connected with a water heater outlet, a cold water pipe connected with a tap water pipe and a water feeding pipe connected between the cold water pipe and a water heater inlet, wherein the circulating water tap is simultaneously connected to the hot water pipe and the cold water pipe, and the water feeding pipe at the water heater inlet or the hot water pipe at the water heater outlet is equipped with a pressurizing water pump. By arranging the switch valve, recycling cold water in the front of the hot water pipe can be realized. In addition, the system has low cost and convenient modification and can recover cold water in any branch to veritably play the role of recycling cold water.

Description

technical field [0001] The invention relates to a circulating water tap which can directly provide hot water and a hot water circulating system. Background technique [0002] With the improvement of people's living standards, various water heaters have become a necessary setting for people's daily life. Water heaters are usually divided into two types: storage type and instant heating type. Storage type water heaters need to wait for a certain period of time before each use. The stored water is hotter, and instant heating water heaters are more flexible to use, so most households use instant heating water heaters. [0003] Instant heating water heaters usually include hot water pipes, cold water pipes and heating devices, wherein the heating devices can use gas heating or electric heating. But there is such a problem in the instant heating water heater, that is, when the user turns on the hot water faucet, the cold water in the pipe needs to be drained to get heated hot wat...
