Gas water heater

Abstract

The invention discloses a novel gas water heater, which comprises a water tank, a heating unit, a water level detection and control unit, a water temperature detection and control unit, and effluent water quantity control unit and an effluent water temperature control unit. A water tank pipeline is connected with a hot water outlet pipe; the effluent water quantity control unit is provided with an effluent control switch, a cylinder body, a piston, a one way switch and a power mechanism; the piston is contained in the cylinder body; the one way switch is used for controlling water flow in the hot water outlet pipe; the power mechanism is used for providing push-pull power for the piston; the pipeline of the hot water outlet pipe is connected with a tempering cold water pipe; and the effluent water temperature control unit is used for controlling the water pressure and flow of the tempering cold water pipe. The novel gas water heater in the invention can realize low water pressure requirement, and saved water resources and energy source and have massage health-care function.

Description

technical field [0001] The invention relates to a water heater, in particular to a novel gas water heater. Background technique [0002] Existing gas water heater has following shortcoming: [0003] ①. After the existing gas water heater is turned on, it needs to wait for several seconds, or even dozens of seconds before hot water flows out. Therefore, during the period from turning on to hot water flowing out, a lot of cold water is wasted and drained because it cannot be used; [0004] ②. During the showering process, the existing gas water heater needs to be paused several times, and some cold water needs to be released after each pause and then turned on, thus causing a lot of waste of water resources; [0005] ③, when the existing gas water heater is started, the power switch is driven by the water pressure of tap water, so there are certain requirements for the water pressure of tap water, and the water pressure is too low to start; The outflow speed of water is fast...

AI Technical Summary

Problems solved by technology

[0003] ①. After the existing gas water heater is turned on, it needs to wait for several seconds, or even dozens of seconds before hot water flows out. Therefore, during the period from turning on to hot water flowing out, a lot of cold water is wasted and drained because it cannot be used;

[0004] ②. During the showering process, the existing gas water heater needs to be paused several times, and some cold water needs to be released after each pause and then turned on, thus causing a lot of waste of water resources;

[0005] ③, when the existing gas water heater is started, the power switch is driven by the water pressure of tap water, so there are certain requirements for the water pressure of tap water, and the water pressure is too low to start; The outflow speed of water is faster, so that the flow of hot water is larger, resulting in double waste of water resources and gas;

[0006] ④. The gas of the existing gas water heater is continuously burned, and the firepower is relatively large, so it is not energy-saving
