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

Abstract

The invention relates to the field of energy saving of water heaters, in particular to a water saving device for water heaters. A water-saving device for a water heater, comprising a cold water injection pipe and a hot water outlet pipe connected to the water heater, the end of the cold water injection pipe far away from the water heater is connected to the cold water inlet pipe, and the end of the hot water outlet pipe far away from the water heater One end of the mixing water pipe is connected with a mixing water pipe, and the end of the mixing water pipe far away from the hot water outlet pipe is connected with the cold water inlet pipe. , the inner outlet pipe is arranged inside the outer return pipe and is not on the same axis as the outer return pipe, and the end of the outer return pipe away from the cold water inlet pipe is connected to a terminal outlet pipe through a return device. The invention does not waste the cold water that flows out when the water heater is just turned on, and avoids the waste of water resources.

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...
