Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0042] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0043] As mentioned above in the background technology, when a traditional electric water heater starts heating, the heating tube generates heat, the adjacent cold water heats up first, and then transfers the heat to the water in other areas through natural convection. The heat exchange efficiency is lower than that of forced convection.

[0044] In order to speed up the heating rate of the water heater, forced convection heat exchange can be used to replace the original natural convection. The current forced convection method is mainly through a rotating shaft rotating through the inner tank, with fan blades fixed at one opposite end of the rotating shaft and a motor fixed at the other end. The motor rotates to drive the rotating shaft to rotate, thereby driving the fan blades to rotate, thereby realizing forced convection of water in the inner tank.

[0045] However, the shaft rotates through the inner tank, and a sealing structure needs to be added at the connection between the shaft and the inner tank. However, because the shaft needs to rotate, the service life of the sealing structure will be greatly reduced, thereby affecting the service life of the electric water heater.

[0046] Therefore, in order to improve or solve the above-mentioned technical problems, an embodiment of the present application provides an electric water heater. In the technical solution provided in the embodiment of the present application, a magnetic field generator and a magnetic fan blade assembly are arranged on the inner tank, so that the magnetic field generator forms a magnetic field in the inner tank, and the magnetic fan blade assembly rotates in the inner tank with the magnetic field as the power, thereby realizing forced convection of water in the inner tank. In the present application, the magnetic field is used as the driving force to avoid the need to set a rotating sealing structure between the inner tank and the magnetic fan blade assembly, thereby avoiding the shortening of the service life of the electric water heater due to the shortening of the service life of the rotating sealing structure.

[0047] Reference below Figure 1-Figure 8 The electric water heater provided in the embodiment of the present application is described in detail.

[0048] Please refer to Figure 1 , Figure 2 and Figure 3 An embodiment of the present application provides an electric water heater, including an inner tank 100, at least one set of magnetic field generators 200 and at least one set of magnetic fan blade assemblies 300.

[0049] Each group of magnetic field generators 200 is arranged on the outside of the inner liner 100 , and the magnetic field generator 200 has two magnetic parts. Each group of magnetic fan blade assemblies 300 is installed in the inner liner 100 , and each group of magnetic fan blade assemblies 300 is respectively located between the two magnetic parts in each group of magnetic field generators 200 .

[0052] Specifically, two groups of magnetic field generators 200 are provided, and two magnetic parts are symmetrically arranged on the outside of the inner liner 100. Two groups of magnetic fan blade assemblies 300 are provided, and the two groups of magnetic fan blade assemblies 300 are symmetrically arranged on the inner liner 100. Both groups of magnetic fan blade assemblies 300 are located in the magnetic field.

[0053] By adopting the above technical solution, when forced convection of the electric water heater is required, the magnetic field generator 200 is started, the magnetic field generator 200 forms a magnetic field in the inner tank 100, and the magnetic fan blade assembly 300 rotates in the inner tank 100 driven by the magnetic field, thereby realizing forced convection of water in the electric water heater. Compared with the prior art, the present application avoids affecting the service life of the electric water heater due to the service life of the rotating sealing structure.

[0054] Please refer to Figure 3In some embodiments provided in the present application, illustratively, the two magnetic members include at least one first electromagnet 210 and at least one second electromagnet 220 , and each first electromagnet 210 and each second electromagnet 220 are respectively located on opposite sides of the inner liner 100 .

[0055] The magnetic poles of the first electromagnet 210 and the second electromagnet 220 on the opposite sides are different, so as to form a magnetic field in the inner container 100 .

[0056] There are two first electromagnets 210 and two second electromagnets 220 , which are respectively located on opposite sides of the inner container 100 , wherein the two first electromagnets 210 and the two second electromagnets 220 are arranged in parallel.

[0057] By adopting the above technical solution, when it is necessary to generate a magnetic field, it is only necessary to energize the first electromagnet 210 and the second electromagnet 220 so that the first electromagnet 210 and the second electromagnet 220 generate magnetism, and the magnetic poles of the first electromagnet 210 and the second electromagnet 220 on opposite sides are different, so as to form a magnetic field in the inner container 100. When it is necessary to turn off the magnetic field, it is only necessary to turn off the power to the first electromagnet 210 and the second electromagnet 220. It is convenient for the user to control the use state of the magnetic field generator 200.

[0058] Please refer to Figure 3 In some embodiments provided in the present application, illustratively, the magnetic fan blade assembly 300 includes a rotating shaft 310 , a rotating fan blade 320 and at least one magnet 330 .
