Detailed Description
In order to make the technical problems solved, technical solutions adopted and technical effects achieved by the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the relevant aspects of the present invention are shown in the drawings.
Fig. 1 shows a pipeline without a water economizer, and cold water between a water outlet pipe 9d of the water heater and a hot water faucet pipe 10a from a water outlet 9b of the water heater to a faucet 10 can be discharged, so that water resources are wasted. FIG. 2 is a water saving device of an internal circulation type for pipeline water, in which a main water inlet pipe 13 is connected to a water heater 9 through a water inlet pipe 9c of the water heater; the water heater 9 is connected with a hot water tap 10 after passing through a water outlet pipe 9d and a hot water tap pipe 10a from a water outlet 9b in sequence; the main water inlet pipe 13 is connected with the cold water faucet 1 after passing through the bidirectional common pipe 12 and the cold water faucet pipe 11a in sequence.
