In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0039] In the prior art, in order to increase the heating speed of water and reduce the installation space of the heating component, the heating component is usually designed as an instant heating component. The existing instant heating component usually directly passes cold water into the instant heating component, and the instant heating component heats the cold water in time. However, the instant heating component greatly reduces the output of hot water. If the output of hot water is increased, the temperature of the output water cannot be guaranteed.

[0040] In order to solve the above problems, Figure 1 and Figure 2 As shown, this embodiment provides an instant heating component 10, which includes a heating body 1 and a water inlet pipe 2, wherein the water inlet pipe 2 includes a cold water inlet pipe 21 and a preheated water inlet pipe 22, and the cold water inlet pipe 21 and the preheated water inlet pipe 22 can both be connected to the heating body 1, and the water inlet of the preheated water inlet pipe 22 is connected to the inner tank 20 of the water heater. The instant heating component 10 provided in this embodiment is provided with a cold water inlet pipe 21 and a preheated water inlet pipe 22 to supply water to the heating body 1, and the cold water inlet pipe 21 is used to pass the cold water in the external tap water into the heating body 1, and the preheated water inlet pipe 22 can pass the hot water in the inner tank 20 into the heating body 1, so that the heating body 1 can be filled with water in a mixed manner of the external cold water and the hot water in the inner tank 20, which not only ensures the outlet water temperature of the heating body 1, but also effectively ensures the water output of the heating body 1 to the hot water.

[0041] Optionally, in this embodiment, the water inlet pipeline 2 also includes a mixed water inlet main pipe 23, and the outlet of the preheated water inlet pipe 22 and the outlet of the cold water inlet pipe 21 are both connected to the inlet of the mixed water inlet main pipe 23, and the outlet of the mixed water inlet main pipe 23 is connected to the heating body 1. By setting the mixed water inlet main pipe 23, the cold water introduced into the cold water inlet pipe 21 and the hot water introduced into the preheated water inlet pipe 22 are mixed evenly in the mixed water inlet main pipe 23 and then introduced into the heating body 1, thereby ensuring the uniformity of the heating of the internal water by the heating body 1. Optionally, in other embodiments, the outlet of the preheated water inlet pipe 22 and the outlet of the cold water inlet pipe 21 can also be directly connected to the heating body 1.

[0042] Optionally, in this embodiment, the water inlet pipeline 2 further includes a flow regulating valve 24, and the outlet of the preheated water inlet pipe 22 and the outlet of the cold water inlet pipe 21 are both connected to the inlet of the mixed water inlet main pipe 23 through the flow regulating valve 24. By setting the flow regulating valve 24, the amount of water introduced into the mixed water inlet main pipe 23 by the cold water inlet pipe 21 and the preheated water inlet pipe 22 is adjusted, so as to accurately adjust the ratio of cold water and hot water introduced into the mixed water inlet main pipe 23, and then accurately control the temperature of the hot water discharged from the heating body 1. Since the specific structure and working principle of the flow regulating valve 24 belong to the prior art, they will not be described in detail here.

[0043] Specifically, when the temperature of the hot water in the inner tank 20 is higher than the required hot water temperature, the amount of cold water passed through the cold water inlet pipe 21 to the mixed water inlet main pipe 23 is appropriately increased to ensure that the temperature of the water discharged from the heating body 1 is the required temperature; when the temperature of the hot water in the inner tank 20 is lower than the required hot water temperature, the amount of cold water passed through the cold water inlet pipe 21 to the mixed water inlet main pipe 23 is appropriately reduced, and the amount of hot water passed through the preheated water inlet pipe 22 to the mixed water inlet main pipe 23 is increased to ensure that the temperature of the water discharged from the heating body 1 is the required temperature.

[0044] Optionally, in this embodiment, the instant heating component 10 also includes a hot water outlet pipe 3, the water inlet of the hot water outlet pipe 3 is connected to the heating body 1, so that the hot water in the heating body 1 is discharged through the hot water outlet pipe 3 to meet the user's demand for hot water.

[0045] In this embodiment, the heating body 1 includes a heating body, a heating element and a heating pipeline, wherein the heating element extends into the interior of the heating body, the heating pipeline is wound around the heating element, the water outlet of the mixed water inlet main pipe 23 is connected to the water inlet of the heating pipeline, and the water outlet of the heating pipeline is connected to the water inlet of the hot water outlet pipeline 3. The mixed water introduced into the mixed water inlet main pipe 23 is heated by the heating element in the process of flowing through the heating pipeline, and then discharged through the hot water outlet pipeline 3. It should be noted that in this embodiment, the heating element can be designed in the form of a heating wire.

[0046] like Figure 2 and Figure 3 As shown, this embodiment further provides a water heater, which includes an inner tank 20 and the instant heating assembly 10, and the water inlet of the preheated water inlet pipe 22 is connected to the inner tank 20. The water heater provided in this embodiment not only ensures the outlet water temperature, but also effectively ensures the outlet water volume of hot water by applying the instant heating assembly 10.

[0047] Optionally, in this embodiment, if Figure 2 and Figure 3 As shown, the instant heating component 10 is located inside the inner tank 20. By arranging the instant heating component 10 in the inner tank 20, the heat emitted by the instant heating component 10 can heat the water in the inner tank 20, avoiding heat waste, improving heat utilization, and avoiding the heat emitted by the instant heating component 10 from damaging the surrounding devices and plastic parts, and also avoiding the heat accumulation in the instant heating component 10 to damage the instant heating component 10. Specifically, in this embodiment, the water heater also includes a first mounting flange 70, which is mounted at the mounting port of the inner tank 20, and the heating body and the heating element in the heating body 1 can be mounted and fixed on the first mounting flange 70. It should be noted that in other embodiments, the heating body and the heating element can also be assembled with the inner tank 20 with their own threads, or a sleeve is welded in the inner tank 20, and the heating body and the heating element are built into the sleeve. Optionally, in other embodiments, the instant heating assembly 10 may also be located outside the inner tank 20 , as long as the preheated water inlet pipe 22 is connected to the inner tank 20 .

[0048] Alternatively, if Figure 2 and Figure 3 As shown, one end of the water inlet of the preheated water inlet pipe 22 extends toward the top of the inner tank 20. Since the hot water portion inside the inner tank 20 is easily stratified, that is, water with a higher temperature is usually located at the top of the inner tank 20, and water with a lower temperature is usually located at the bottom of the inner tank 20, by extending one end of the water inlet of the preheated water inlet pipe 22 toward the top of the inner tank 20, the water inlet of the preheated water inlet pipe 22 is as close to the top of the inner tank 20 as possible, thereby ensuring the stability of the preheated water inlet pipe 22 passing hot water, and improving the user's hot water experience.

[0049] In this embodiment, if Figure 2 As shown, the water heater further includes a heat storage heating component 60, which is installed in the inner tank 20. The heat storage heating component 60 can heat the water in the inner tank 20 in a heat storage manner to ensure the temperature of the hot water in the inner tank 20. Specifically, in this embodiment, the heat storage heating component 60 can be designed in the form of a heating rod. In addition, as Figure 3 As shown, the water heater further includes a second mounting flange 80 , which is mounted at the mounting opening of the inner tank 20 , and the thermal storage heating assembly 60 is mounted and fixed on the second mounting flange 80 .

[0050] Optionally, in this embodiment, if Figure 2 As shown, the heat storage heating assembly 60 is located at the bottom of the preheated water inlet pipe 22 and the heating body 1. Specifically, the heat storage heating assembly 60 is arranged as close to the bottom of the inner tank 20 as possible. Since the water with a lower temperature in the inner tank 20 is usually located at the bottom of the inner tank 20, the heat storage heating assembly 60 can better heat the water in the inner tank 20, effectively improving the uniformity of the temperature of the water in the inner tank 20 at various positions.

[0051] In this embodiment, if Figure 2 As shown, the water heater further includes a cold water inlet main pipe 30, an inner tank inlet pipe 40 and a three-way valve 50, wherein the water inlet of the inner tank inlet pipe 40 and the water inlet of the cold water inlet pipe 21 are both connected to the water outlet of the cold water inlet main pipe 30 through the three-way valve 50, and the inner tank inlet pipe 40 is used to pass cold water into the inner tank 20. By passing cold water in external tap water into the cold water inlet main pipe 30, a part of the cold water in the cold water inlet main pipe 30 can be passed into the mixed water inlet main pipe 23 through the cold water inlet pipe 21, and then passed into the heating body 1, and the remaining part of the cold water in the cold water inlet main pipe 30 is directly passed into the inner tank 20 through the inner tank inlet pipe 40, thereby realizing the replenishment of water in the inner tank 20. In addition, by providing a three-way valve 50 , it is convenient to adjust the ratio of cold water introduced into the inner tank water inlet pipe 40 and the cold water inlet pipe 21 to ensure that the required flow of cold water is introduced into the inner tank 20 or the heating body 1 .

[0052] Optionally, in this embodiment, if Figure 2 As shown, a plurality of cold water outlet holes 401 are spaced apart on the side wall of the portion of the inner tank water inlet pipe 40 extending into the inner tank 20. In this embodiment, the plurality of cold water outlet holes 401 are spaced apart along the axial direction and circumferential direction of the inner tank water inlet pipe 40, so that the inner tank water inlet pipe 40 discharges cold water into the inner tank 20 in a form of diffusion in all directions, so that the cold water is more evenly mixed into the inner tank 20, thereby avoiding the local water temperature in the inner tank 20 being too low. In this embodiment, the thermal storage heating assembly 60 is arranged close to the cold water outlet hole 401, so that the thermal storage heating assembly 60 can heat the cold water entering the inner tank 20 in a timely manner.

[0053] In this embodiment, the position of each cold water outlet hole 401 is lower than the position of the preheated water inlet pipe 22 and the heating body 1, and each cold water outlet hole 401 is arranged as close as possible to the bottom wall of the inner tank 20. The position of the cold water outlet hole 401 is arranged so that the preheated water inlet pipe 22 is far away from the cold water outlet hole 401, which can prevent the preheated water inlet pipe 22 from directly discharging the cold water discharged from the cold water outlet hole 401 and affecting the temperature of the hot water discharged from the heating body 1, thereby ensuring the stability of the temperature of the hot water discharged from the heating body 1 and improving the hot water experience of the user.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
