Embodiment 1

[0051] Such as Figure 1-2 As shown, a gas water heater capable of multi-stage current limiting and temperature control in this embodiment includes a burner 1, a heat exchanger 2, a water inlet pipe 31, a water outlet pipe 32, an outlet water temperature detection device 41, a water flow detection device 5, a gas The proportional valve 6, the first water regulating device 7 and the controller 8, the water inlet end and the water outlet end of the heat exchanger 2 communicate with the water inlet pipe 31 and the water outlet pipe 32 respectively, and the water inlet end of the water inlet pipe 31 communicates with the water inlet joint 30, The water outlet end of the water outlet pipe 32 communicates with the external hot water pipe 33 . The outlet water temperature detection device 41 is arranged on the outlet pipe 32 and is electrically connected with the controller 8 for detecting the outlet water temperature of the outlet pipe 32 in real time. The water flow detection devi...

Embodiment 2

[0063] Such as Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that a main current stabilizer 10 is also included. The main flow stabilizer 10 is set in the water inlet joint 30 or in the water inlet end of the first main waterway 711, and the flow limit value of the main flow stabilizer 10 is the maximum water flow of the water heater, and other components are the same as in the first embodiment. In this embodiment, the main flow stabilizer 10 is disposed in the water inlet joint 30 for controlling the maximum water flow of the water heater.

[0064] It can be seen that by adding the main flow stabilizer 10 for controlling the maximum water flow of the water heater in the water inlet joint 30, the maximum water flow of the water heater is more stable, which is beneficial to accurately control the water flow of the water heater, and avoids excessive tap water supply pressure. Affect the constant temperature of the water heater to produce hot wat...

Embodiment 3

[0066] The difference between this embodiment and Embodiment 1 is that the second water regulating device 9 is omitted, and other parts are the same as Embodiment 1. When the first bypass waterway 712 is closed, the flow of water is limited by the first flow stabilizer 72 of the first water regulating device 7, and the water heater is in the primary water flow gear, that is, the minimum water flow gear; when the first bypass When the waterway 712 is opened, the flow of water is not limited by the first flow stabilizer 72 of the first water regulating device 7, and the water heater is at the secondary water flow gear, that is, the maximum water flow gear.

[0067] It can be seen that by omitting the first water regulating device 7 or the second water regulating device 9, while realizing multi-level control of water flow, it is beneficial to reduce the manufacturing cost.

Abstract

The invention discloses a gas water heater capable of achieving multi-stage flow limiting and temperature control. The gas water heater comprises a burner, a heat exchanger, a water inlet pipe, a water outlet pipe, a discharged water temperature detecting device, a water flow detecting device, a gas proportional valve, a first water adjusting device and a controller; the first water adjusting device comprises a first valve body, a first flow stabilizer and a control valve; the first valve body is provided with a first main water way and a first bypass water way; the two ends of the first mainwater way communicate with externally supplied water and a water inlet end of the water flow detecting device correspondingly, and the first main water way is provided with the first flow stabilizer;the water inlet end and the water outlet end of the first bypass water way communicate with the water inlet end and the water outlet end of the first flow stabilizer correspondingly; and the control valve is arranged on the first valve body and used for controlling opening and closing of the first bypass water way. Through the gas water heater of the invention, the quick temperature rising effectcan be achieved, the waiting time is shortened, the wasting quantity of cold water is decreased, and meanwhile, the influence of water supply pressure on the temperature rising stage can be reduced.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a multi-stage current limiting control technology for water heaters. Background technique [0002] At present, for ordinary constant temperature gas water heaters, when the user turns on the hot water tap for the first time, tap water flows into the water heater. At this time, the water flow sensor device in the main waterway of the gas water heater detects that there is water flowing through, and then opens the gas valve to ventilate and ignite the tap water to heat the water and ignite it. Then control the opening of the gas valve according to the difference between the preset temperature and the outlet water temperature, so that the outlet water temperature gradually reaches the preset temperature of the gas water heater and realizes constant temperature hot water output. However, the interval from the monitoring of the water flow signal to the ignition of the water heat...
