Example Embodiment
[0027] Implementation mode one
[0028] Such as figure 1 As shown, the water heater in this embodiment is a gas water heater, which includes a water inlet 101, a water outlet 102, and a water pipe 103 connected to the water outlet 102, and a water valve 104 is provided at the water outlet end of the water pipe 103; Since the existing water heater needs to drain the cold water in the water pipe 103 before use, it will cause a waste of water resources and require users to wait. To solve this problem, in this embodiment, a heating device 105 is provided on the water pipe 103. The heating device 105 is an electric heating wire or an electric heating belt, which is used to heat the water in the water pipe so that the user can Hot water is obtained when the water heater is turned on, which avoids the previous waste of cold water and reduces the waiting time for users.
[0029] The above-mentioned electric heating belt is a belt-shaped structure with electric heating wires inside, and th...
Example Embodiment
[0036] Implementation mode two
[0037] Such as figure 2 As shown, in this embodiment, the temperature sensor 206 is arranged near the water outlet end of the water pipe 203. Since the temperature sensor 206 is arranged near the water outlet end of the water pipe 203, the detected water temperature information is closer to The water temperature to be used by the user further improves the accuracy of the water temperature control in the water pipe 203. In this embodiment, except that the location of the temperature sensor is different from that of the first embodiment, the other structures are the same as those of the first embodiment.
Example Embodiment
[0038] Implementation mode three
[0039] Such as image 3 As shown, in this embodiment, the heating device 305 is formed by an electric heating wire in a form of cross-wound left and right spirals to form a grid structure. The heating device 305 of this structure heats the water in the water pipe 303 higher efficiency. In this embodiment, except that the structure of the heating device is different from the first or second embodiment, the other structures are the same as those of the first or second embodiment.
