Water-saving hot pipe of water heater

Abstract

The invention relates to a water-saving hot pipe of a water heater. The water-saving hot pipe of the water heater comprises an outer pipe, the outer pipe comprises a fixing layer, a heat preservationlayer and a protection layer, a water-saving strip is arranged on the axis of the outer pipe, the water-saving strip comprises supporting pieces, a water-saving bag made of an elastic material is hermetically wrapped outside the water-saving strip, the inner wall of the water-saving bag is fixedly connected with the side walls, close to the outer sides, of the supporting pieces, the water-saving bag communicates with a gas guide valve arranged on the wall of the outer pipe, adjusting pieces are arranged on the inner pipe wall of the outer pipe, the adjusting pieces are made of thermal expansion strips, when the adjusting pieces are heated, the adjusting pieces expand in the radial direction of the outer pipe, each adjusting piece is arranged between the two adjacent supporting pieces, andthe side walls of the adjusting pieces are fixedly connected with the outer wall of the water-saving bag. According to the water-saving hot pipe, residual water in the hot water pipe can be effectively reduced when water is not used, so that waste of water resources is reduced, and meanwhile, the waiting time for water use is shortened.

Description

technical field [0001] The invention relates to a water heater fitting, in particular to a hot water pipe. Background technique [0002] The water heater is a commonly used household appliance. The main unit of the water heater is often set in the kitchen, and is distributed to other rooms through hot water pipes and cold water pipes, so as to ensure that all rooms have hot water for use; The road is long, and if no hot water is used for a period of time, the hot water remaining in the hot water pipe will cool down naturally; when hot water is needed, the user needs to wait for the cooled hot water from the hot water pipe to be discharged before the hot water can be used again. This process takes a long time to wait, and the cold water discharged from the hot water pipe will basically not be recycled, resulting in a certain waste of water resources; and currently there is no suitable method to save these precious water resources.
