[0002] At present, water heaters are household appliances commonly used in people's daily lives. Storage-type electric water heaters are equipped with water tanks, which have the characteristics of large water output and stable water temperature, and are purchased and used by more families. For conventional storage-type electric water heaters, they usually include components such as water tanks, electric heating components and electric control panels. Among them, in order to protect the inner tank to avoid or slow down corrosion, the water tank is usually treated with anti-corrosion. Conventional methods include adding magnesium rods to the inner tank of the water tank or adding external electronic anodes.

[0003] Among them, the use of an external electronic anode to perform anti-corrosion treatment on the inner tank can avoid the formation of scale in the inner tank due to the use of a magnesium rod.

[0036] An electric water heater uses electricity as its main energy source. The high-temperature heat generated after power is turned on directly heats the water stored in the electric water heater to prepare hot water.

[0037] An electric water heater usually includes a water tank, an electric heating component, an electric control board and other components. A water storage cavity is formed in the water tank to store the water to be heated. The electric heating component is inserted into the water storage cavity formed by the water tank. The electric control board is used to control the on and off operation of the electric heating component so that the water in the water tank is heated to a set temperature.

[0038] For the water tank of an electric water heater, the water tank generally includes an outer shell and an inner tank, and an insulation layer is formed between the outer shell and the inner tank. Among them, the outer shell is generally made of plastic material to meet the design requirements of beautiful and diverse shapes; the inner tank can be made of metal or plastic according to needs.

[0039] In addition, the insulation layer formed between the outer shell and the inner liner, commonly used insulation materials include: asbestos, sponge, foam plastic, polyurethane foam, etc. In conventional technology, in order to obtain a good insulation effect, the insulation layer is usually formed by foaming.

[0040] Among them, for the inner tank using a metal tank body, the interior of the inner tank is prone to corrosion due to the influence of water quality. For this reason, a magnesium rod is also configured on the water tank, and the magnesium rod is inserted into the water storage cavity inside the water tank.

[0041] Since magnesium is the metal with the lowest potential in the electrochemical series and is physiologically non-toxic, it is ideal for making magnesium rods to protect the inner liner. The size of the magnesium rod is directly related to the length of time the inner liner is protected and the size of the protective effect. The larger the magnesium rod, the better the protective effect and the longer the protection time.

[0042] The water tank is also provided with a water inlet pipe and a water outlet pipe. The water inlet pipe is used to transport cold water to the water storage cavity formed in the water tank, while the hot water in the water storage cavity is output from the water outlet pipe.

[0043] For the electric heating component, electric heating methods such as electric heating wire, magnetic energy or silicon tube heating can be used to heat the water stored in the water storage cavity.

[0044] As for the electric control board, it is used to receive the detection signals sent by relevant sensors (such as water temperature sensors, flow sensors), and at the same time, control the power on and off operation of the electric heating components.

[0045] When the electric water heater is working, the electric control board controls the electric heating component to be powered on for heating. When the water temperature in the water tank reaches the set value, the electric control board controls the electric heating component to be powered off.

[0046] Embodiment 1, as Figure 1-Figure 6 As shown, an embodiment of the present application provides a water heater, comprising: A water tank, the water tank comprising a tank shell 1 and an inner tank 2, wherein the inner tank 2 is arranged in the tank shell 1; A heating module 3, which is disposed inside the housing 1 and is configured to heat the water in the inner tank 2; An electronic anode, the electronic anode is arranged in the inner container 2; a power supply module 4, wherein the power supply module 4 is configured to supply power to the electronic anode; The housing 1 is provided with a mounting portion 11 , and the power supply module 4 is detachably disposed on the mounting portion 11 .

[0047] Specifically, for the water heater, the heating module 3 is used to heat the water stored in the inner tank 2, wherein the specific entity of the heating module 3 is determined according to the heating method of the water heater, for example: if the water heater is an electric water heater, the corresponding heating module may be an electric heating tube; or if the water heater is a heat pump water heater, the corresponding heating module may be a heat exchange tube for the heat exchange medium to flow. Here, there is no limitation on the specific entity of the heating module 3.

[0048] In order to perform current corrosion protection treatment on the inner tank 2, an electronic anode is provided on the inner tank 2. The power supply of the electronic anode can be supplied by at least the power supply module 4. The power supply module 4 has the function of storing electricity. In this way, during the process of the power supply module 4 supplying power to the electronic anode, even if the power supply of the water heater is cut off, it will not affect the power supply module 4 to continue to supply power to the electronic anode.

[0049] In order to facilitate the user to replace and maintain the power supply module 4 in time, a mounting portion 11 is correspondingly provided on the box shell 1, and the mounting portion 11 satisfies the installation requirements of the power supply module 4, thereby realizing the assembly and use of the power supply module 4 outside the box shell 1. In the later use process, when the power supply module 4 needs to be replaced or maintained, there is no need to disassemble the box shell 1, and the power supply module 4 can be replaced by only removing it from the mounting portion 11.

[0050] In addition, for the specific appearance of the mounting portion 11, the mounting portion 11 can be an integrated structure with the box shell 1, that is, a corresponding structure for mounting the power supply module 4 is formed on the box shell 1, for example, it can be a groove or a boss. Alternatively, the mounting portion 11 and the box shell 1 are split structures, and the mounting portion 11 can be mounted on the box shell 1 by means of snap connection, screw fixing, etc. Here, the specific appearance of the mounting portion 11 is not limited or repeated.

[0051] In one embodiment, the power supply module 4 generally includes a battery 41 to meet the need for storing electric energy. The battery 41 can store electric energy to power the electronic anode. During the sales process of the water heater, the water heater can be randomly configured with the battery 41 when the whole water heater is sold as needed; or the water heater can be sold without the battery 41, and the user can purchase it separately or the after-sales installer can carry it for installation. There is no restriction here.

[0052] In another embodiment, in order to facilitate the installation of the battery 41, the power supply module 4 further includes a battery 41, a battery cavity is formed in the protective shell 42, and the battery 41 is located in the battery cavity; The protective shell 42 is detachably disposed on the mounting portion 11 .

[0053] Specifically, the power supply module 4 includes a protective shell 42 , so that the battery 41 can be independently installed through the protective shell 42 , and the power supply module 4 can be fixedly installed on the box shell 1 through the protective shell 42 .

[0054] The mounting portion 11 is provided with a mounting groove 111, and the mounting groove 111 is provided with a plug hole and a threaded hole 113; The protective shell 42 is provided with a first plug tongue 421 and a fixing hole 422 . The protective shell 42 is disposed in the mounting groove 111 . The first plug tongue 421 is inserted into the plug hole. A screw passes through the fixing hole 422 and is threadedly connected in the threaded hole 113 .

[0055] Specifically, in order to facilitate disassembly and installation, a first plug tongue 421 and a fixing hole 422 may be correspondingly provided on the protective shell 42, and one end of the protective shell 42 is inserted into the plug hole of the mounting portion 11 through the first plug tongue 421 to complete the positioning; then, the other end of the protective shell 42 is screwed through the fixing hole 422 and threadedly fixed in the threaded hole 113.

[0056] In this way, a single screw can be used to meet the requirements for fixed installation of the power supply module 4, reducing the number of screws used to provide convenience in operation and maintenance.

[0057] In addition, the protective shell 42 includes a first shell 423 and a second shell 424 , the first shell 423 and the second shell 424 are detachably connected together, and the battery 41 is located between the first shell 423 and the second shell 424 .

[0058] Specifically, the protective shell 42 is of split design, and is assembled from a first shell 423 and a second shell 424 , so that the battery 41 is installed between the first shell 423 and the second shell 424 .

[0059] Furthermore, in order to facilitate the assembly of the first shell 423 and the second shell 424, the two sides of the first shell 423 are respectively provided with protrusions 4231, and the first end of the protrusion 4231 is provided with a first slot 4232; The two sides of the second housing 424 are provided with snap-fitting protrusions 4241 , and the snap-fitting protrusions 4241 are snap-fitted into the first snap-fitting grooves 4232 on the corresponding sides.

[0060] Specifically, during the process of replacing the battery 41, the engaging protrusion 4241 is pulled out from the first engaging groove 4232 to separate the first housing 423 and the second housing 424. After replacing the battery 41, the engaging protrusion 4241 is inserted into the first engaging groove 4232 to achieve the screwless assembly of the first housing 423 and the second housing 424.

[0061] Furthermore, both sides of the second housing 424 are provided with limiting protrusions 4242, and the limiting protrusions 4242 abut against the second end of the protrusion 4231; The first end and the second end of the protrusion 4231 are arranged opposite to each other.

[0062] Specifically, in order to improve the connection reliability between the first housing 423 and the second housing 424, a limiting protrusion 4242 is provided on the second housing 424, and the limiting protrusion 4242 is arranged at an interval with the clamping protrusion 4241. After the clamping protrusion 4241 is clamped into the first clamping groove 4232, the limiting protrusion 4242 will abut against the end position of the protrusion 4231 away from the first clamping groove 4232, thereby limiting the clamping protrusion 4241 from being separated from the first clamping groove 4232.

[0063] In another embodiment, the protective shell 42 may further include a sleeve and an end cover, one end of the sleeve is a closed structure, and the other end of the sleeve is an open structure, the battery 41 is inserted into the sleeve through the opening structure of the sleeve, and the end cover is detachably arranged on the opening structure of the sleeve.

[0064] Specifically, the use of a sleeve can also meet the installation protection requirements of the battery 41. The battery 41 is inserted into the sleeve and covered and protected by the end cover.

[0066] Specifically, since the battery 41 is protected by the protective shell 42 , the wire connected to the battery 41 will pass through the first wiring hole 425 from the protective shell 42 , thereby satisfying the electrical connection between the wire and the electronic anode.

[0067] In another embodiment of the present application, Figure 7-Figure 14As shown, in order to facilitate the installation of the battery 41, the power supply module 4 also includes a protective cover 43, and the protective cover 43 is detachably arranged on the mounting portion 11. A battery cavity is formed between the protective cover 43 and the mounting portion 11, and the battery 41 is located in the battery cavity.

[0068] Specifically, a space for directly installing the battery 41 is correspondingly formed on the mounting portion 11 . After the battery 41 is installed on the mounting portion 11 , the battery 41 is protected externally by the protective cover 43 .

[0069] In this way, the battery 41 is disposed in the battery cavity formed between the protective cover 43 and the mounting portion 11 , and the battery 41 supplies power to the electronic anode on the inner liner 2 , so as to provide current corrosion protection to the inner liner 2 through the electronic anode.

[0070] Since the battery 41 is installed in the battery cavity formed by the protective cover 43 and the mounting portion 11, when the power supply module 4 needs to be replaced or maintained, it is only necessary to remove the protective cover 43 from the mounting portion 11 to conveniently remove the battery 41 from the mounting portion 11.

[0071] In order to facilitate the pre-positioning and installation of the battery 41 , a mounting groove 111 may be provided on the mounting portion 11 , so that the battery 41 is first placed in the mounting groove 111 , and then the protective cover 43 is installed on the mounting portion 11 to cover the mounting groove 111 .

[0072] In one embodiment, in order to achieve the requirement of screwless installation and disassembly and to facilitate later disassembly by operators or users, the protective cover 43 can be installed on the installation portion 11 by plug-in or clip-on methods.

[0073] Specifically, in the plug-in manner, a second plug tongue 431 is provided on the protective cover 43 , and correspondingly, a second plug hole 115 is provided on the mounting portion 11 , and the second plug tongue 431 is inserted into the second plug hole 115 to enable the protective cover 43 to be plugged into the mounting portion 11 .

[0074] Specifically, during the assembly process, the second tongue 431 on the protective cover 43 can be inserted into the second insertion hole 115 provided on the mounting portion 11, and then the protective cover 43 is pushed so that the second tongue 431 is fully inserted into the second insertion hole 115 to complete the plug-in installation.

[0075] The mounting portion 11 is also provided with an auxiliary positioning plate 116, which extends to the outside of the box shell 1, and is arranged adjacent to one end of the protective cover 43 and covered by the protective cover 43, and the second plug tongue 431 of the protective cover 43 extends toward the auxiliary positioning plate 116.

[0110] In some embodiments, a plurality of annular ribs 522 arranged side by side are disposed on the outer surface of the conductive rod 52 , and the annular ribs 522 are located in the insulating mounting seat 53 .

[0111] Specifically, the provision of the annular ribs can increase the contact area between the conductive rod 52 and the insulating mounting seat 53, and further increase the flow path of water leakage when a gap occurs between the two, which is more conducive to improving the reliability of use.

[0118] By adding a first sealing ring at the connection position between the first end of the insulating mounting seat and the conductive rod, the connection position between the insulating mounting seat and the conductive rod is effectively sealed on the outside of the insulating mounting seat by the first sealing ring. Even if gaps are formed between the insulating mounting seat and the electrode rod and the conductive rod, water in the inner tank will be sealed and blocked by the first sealing ring at the first end of the insulating mounting seat when flowing outward through the gaps, so as to effectively improve the sealing performance of the electronic anode and improve the reliability of the water heater.
