Water-saving device for water heater

Abstract

The invention relates to the field of energy saving of water heaters, in particular to a water-saving device for a water heater. The water-saving device for the water heater comprises a cold water injection pipe and a hot water outlet pipe which are connected to the water heater, wherein the end, far away from the water heater, of the cold water injection pipe is connected with a cold water inletpipe, and a mixed water pipe is connected to the end, far away from the water heater, of the hot water outlet pipe; the end, far away from the hot water outlet pipe, of the mixed water pipe is connected with the cold water inlet pipe, and the mixed water pipe is connected with a water outlet inner pipe; and the cold water inlet pipe is connected with a backflow outer pipe, the water outlet inner pipe is arranged in the backflow outer pipe and is not on the same axis as the backflow outer pipe, and the end, far away from the cold water inlet pipe, of the backflow outer pipe is connected with aterminal water outlet pipe through a backflow device. According to the water-saving device, cold water flowing out when the water heater is just opened cannot be wasted, and waste of the water resource is avoided.

Description

technical field [0001] The invention relates to the field of energy saving of water heaters, in particular to a water saving device for water heaters. Background technique [0002] With the development of social industry, various high-efficiency water heaters emerge in endlessly in terms of water heaters, and the efficiency of water heaters is also getting higher and higher. Today's electric water heaters, solar water heaters, and air energy water heaters are becoming more and more common, but they still exist. Some problems, that is, when the water heater just starts to work, the temperature of the water out of the water outlet is not high, causing the cold water with insufficient temperature to be directly released, resulting in a waste of water resources. Contents of the invention [0003] The present invention mainly aims to provide a water-saving device for water heaters, aiming at the problem that the water outlet temperature is not high when the existing water heate...

Problems solved by technology

[0003] The present invention mainly aims to provide a water-saving device for water heaters, aiming at the problem that the water outlet temperature is not high when the existing water heaters just start to work, causing the cold water with insufficient temperature to be released directly, resulting in waste of water resources. The cold water that flows out when the water heater is just turned on will not be wasted, avoiding the waste of water resources
