[0001] The utility model relates to a heating element of an instant water heater with an energy storage function. Background Art

[0002] At present, instant water heaters are becoming more and more popular. For the sake of electricity safety, the power of instant water heaters is limited. On the one hand, in winter or in the cold climate in the north, the power of instant water heaters is insufficient, resulting in a small amount of hot water output, or even the temperature failing to reach the user's set value, resulting in a poor bathing experience. In addition, the existing storage water heaters heat the water directly through heating tubes. After a long time, the heating tubes will be scaled or even burst, resulting in a short service life and high after-sales maintenance costs. Summary of the invention

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a heating element for an instant water heater with an energy storage function. When the power of the instant water heater is limited, in winter or in the cold climate in the north, the hot water output is sufficient and the temperature reaches the user's set value. The heating tube does not directly heat the water, and there will be no tube burst due to scale. The service life is long and the after-sales maintenance cost is low.

[0005] A heat-conducting layer, an outer coil, a water inlet pipe and a connecting pipe; the heat-conducting layer is wrapped around the outer side of the heat-conducting inner liner, the outer coil is arranged in the heat-conducting layer and coiled around the outer side of the inner coil, the heat-conducting layer fills the gap between the heat-conducting inner liner and the outer coil, the water outlet of the outer coil is connected to the water inlet of the inner coil through the connecting pipe, and the water inlet of the outer coil is connected to the water inlet pipe;

[0006] The outer shell and the thermal insulation layer; the thermal insulation layer is wrapped around the outer side of the heat-conducting layer, the outer shell is wrapped around the outer side of the thermal insulation layer, the water outlet pipe passes through the outer shell and the thermal insulation layer to communicate with the external water outlet pipe, and the water inlet pipe passes through the outer shell and the thermal insulation layer to communicate with the external water inlet pipe.

[0009] Compared with the prior art, the advantages of the utility model are as follows: when the power of the instant water heater is limited, in winter or in the cold climate in the north, the hot water output is sufficient and the temperature reaches the user's set value, and the heating tube is not directly immersed in water for heating, and there will be no tube burst due to scale generated on the surface of the heating tube, the service life is long, and the after-sales maintenance cost is low.

[0016] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various implementation methods of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0017] In the description of the present invention, the terms "front", "rear", "upper", "lower", "one side" and "the other side" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention.

[0018] like Figures 1 to 6 As shown, it is an instant water heater with energy storage function, including

[0019] A heating tube 8, an inner coil 10, a heat-conducting inner liner 12 and a water outlet pipe 4; the heating tube 8 and the inner coil 10 are respectively arranged in the heat-conducting inner liner 12, the inner coil 10 is coiled on the outside of the heating tube 8, and the water outlet of the inner coil 10 is connected to the water outlet pipe 4;

[0020] A heat-conducting layer 13, an outer coil 6, a water inlet pipe 3 and a connecting pipe 9; the heat-conducting layer 13 is wrapped around the outside of the heat-conducting inner liner 12, the outer coil 6 is arranged in the heat-conducting layer 13 and coiled around the outside of the inner coil 10, the heat-conducting layer 13 fills the gap between the heat-conducting inner liner 12 and the outer coil 6, the water outlet of the outer coil 6 is connected to the water inlet of the inner coil 10 through the connecting pipe 9, and the water inlet of the outer coil 6 is connected to the water inlet pipe 3;

[0021] The outer shell 1 and the thermal insulation layer 5; the thermal insulation layer 5 is wrapped around the outside of the heat-conducting layer 13, the outer shell 1 is wrapped around the outside of the thermal insulation layer 5, the water outlet pipe 4 passes through the outer shell 1 and the thermal insulation layer 5 to communicate with the external water outlet pipe, and the water inlet pipe 3 passes through the outer shell 1 and the thermal insulation layer 5 to communicate with the external water inlet pipe.

[0022] The utility model has two usage states:

[0023] First, when the user has finished using the hot water and turns off the water heater, the residual heat of the heating tube 8 and the inner coil 10 will be transferred to the outer coil 6 through the heat-conducting inner tank 12 and the heat-conducting layer 13, which will preheat the water in the outer coil 6, thereby enhancing the utilization of energy and avoiding the waste of heat energy. When the next user uses it, since the water in the outer coil 6 has been preheated, in winter or in the cold climate in the north, the hot water output is sufficient and the temperature reaches the user's set value.

[0024] The second method is to turn on the water heater in advance and set it. The heating tube 8 preliminarily heats the water in the inner coil 10 and the outer coil 6 (equivalent to the water tank of the storage water heater), and heats the heat conductive layer 13 at the same time. The heat energy is stored in the heat conductive layer 13. When the user uses hot water, the water entering the outer coil 6 will absorb the heat of the heat conductive layer 13 through the outer coil 6, thereby increasing the water inlet temperature; in winter or in the cold climate in the north, the hot water output is sufficient and the temperature reaches the user's set value.

[0025] In addition, the heating tubes of the above two solutions are not directly immersed in water for heating, and there will be no tube bursting due to scale generated on the surface of the heating tubes. The service life is long and the after-sales maintenance cost is low.

[0026] In this embodiment, a temperature control probe 2 is further included, and the temperature control probe 2 is arranged on the inner coil 10 .

[0027] The temperature control probe 2 further monitors the temperature of the instant water heater and controls it accurately.

[0028] In this embodiment, the heat-conducting inner liner 12 is made of aluminum. The heat-conducting inner liner 12 can also be made of a variety of heat-conducting materials.

[0029] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For ordinary technicians in this field, various changes, modifications, substitutions and deformations of these embodiments without departing from the principle and purpose of the present invention still fall within the scope of protection of the present invention.
