Problems solved by technology

Especially in winter, the preheating temperature of the gas water heater is higher, the temperature of the tap water is lower, and the heating time of the gas water heater is longer, so that the user waits longer for the hot water, which makes the user easy to catch cold and wastes more tap water

Embodiment 1

[0053] Such as Figures 1 to 4As shown, this embodiment provides a constant temperature gas water heater, including a water heater body 1, a heat exchanger 2 disposed inside the water heater body 1, and a connecting pipe 3, wherein a gas valve 4 is provided at the inlet end of the water heater body 1, and the water heater The main body 1 is connected with the water inlet pipe 5 and the water outlet pipe 6 respectively. One end of the connecting pipe 3 communicates with the water inlet pipe 5, and the other end passes through the heat exchanger 2 and communicates with the water outlet pipe 6. A water flow sensing device 31 is arranged on the connecting pipe 3. The pipe 3 is provided with an outlet water temperature detection device 32 at one end close to the outlet pipe 6, and also includes a flow stabilization device 7 arranged on the connecting pipe 3, the flow stabilization device 7 includes:

Embodiment 2

[0066] Such as Figure 5 and 6 As shown, this embodiment provides a constant temperature control method for a gas water heater, which is applied to the constant temperature gas water heater as in Embodiment 1. The constant temperature control method includes the following steps:

[0067] Step S101, the gas water heater closes the first on-off valve and the second on-off valve to enter the standby mode.

[0068] In this embodiment, the gas water heater is at the preset first water flow gear during the heating-up stage, that is, at the minimum water flow gear, so that the water flow rate is small, the hot water temperature rises quickly, and the waiting time for hot water is shortened. By limiting the water flow when starting up, the purpose of quickly producing hot water and reducing water waste can be achieved.

[0069] Step S102, turn on the hot water faucet, judge whether the actual water flow value is greater than or equal to the preset start-up water flow value, if yes, ...

Abstract

The invention discloses a constant-temperature gas water heater and a constant-temperature control method thereof. The constant-temperature gas water heater is characterized in that a main water pathcommunicates with a first bypass water path and a second bypass water path, water inlets of the first bypass water path and the second bypass water path are formed in the front end of a water inlet ofa first flow stabilizing valve correspondingly, and water outlets of the first bypass water path and the second bypass water path are formed in the rear end of a water outlet of the first flow stabilizing valve; and a first switch valve is arranged on the first bypass water path and used for controlling connection and disconnection of the first bypass water path, and a second switch valve is arranged on the second bypass water path and used for controlling connection and disconnection of the second bypass water path, so that the gas water heater achieves switching of three levels of water flow gears through controlling opening and closing of the first switch valve and the second switch valve. The constant-temperature gas water heater is simple in structure, the purpose of accurately controlling the water outlet temperature is achieved through switching water flow gears and adjusting the opening degree of a gas valve, and then rapid constant-temperature water outlet is achieved.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a constant temperature gas water heater and a constant temperature control method thereof. Background technique [0002] In related technologies, most of the gas water heaters flow out cold water for a period of time after turning on the hot water faucet, and then hot water flows out. It usually takes more than 30 seconds from turning on the hot water faucet until comfortable hot water flows out. Users need to wait for the cold water to run out before using hot water, which is a waste Plenty of running water. The heating time of a gas water heater is affected by factors such as the set temperature, tap water temperature, and water supply flow. Generally, the higher the set temperature, the lower the tap water temperature, and the greater the supply water flow, the longer it takes for the outlet water temperature to reach the preset temperature. Especially in winter, the pr...
