Description

Technical Field

[0001] This utility model belongs to the field of electrical equipment technology, and in particular relates to an inner tank module and a water heater. Background Technology

[0002] Currently, water heaters are common household appliances. Storage-type electric water heaters, equipped with a water tank, are increasingly popular due to their large water output and stable water temperature. A typical storage-type electric water heater usually consists of a water tank, an electric heating element, and an electronic control board. To protect the inner tank from corrosion, the water tank is typically treated with anti-corrosion measures, usually including adding a magnesium rod or an external electron anode.

[0003] One method involves using an external electronic anode for corrosion protection of the inner tank, avoiding the scale buildup that can occur with magnesium rods. During actual use, the external electronic anode requires power. Chinese Patent Publication No. CN 217504011 U discloses an electronic anode, a water storage device, and a water heater that uses an electronic anode for corrosion protection. In practical use, during the corrosion protection process, the electronic anode electrolyzes the water in the inner tank, producing hydrogen gas. After prolonged use, when the hydrogen gas accumulates to a certain level, causing the water level to drop and exposing the electric heating element, the exposed element coming into contact with the hydrogen gas can easily explode. Therefore, the electronic anode needs to be positioned above the electric heating element. However, the installation height of the electronic anode limits the installation height of the electric heating element within the inner tank, thus limiting its heating capacity and resulting in lower heating efficiency for the water heater.

[0004] Therefore, the technical problem to be solved by this utility model is how to design a water heater that meets the installation requirements of the electronic anode height and increases the installation range of the electric heating element in the inner tank. Utility Model Content

[0057] An electric water heater is a type of water heater that uses electricity as its primary energy source. The high-temperature heat generated after the power is turned on directly heats the water stored in the water heater to produce hot water.

[0058] Electric water heaters typically consist of a water tank, an electric heating element, and an electronic control board. The water tank has a storage cavity to store water to be heated. The electric heating element is inserted into the storage cavity of the water tank. The electronic control board is used to control the electric heating element to operate by turning the power on and off, so that the water in the tank is heated to the set temperature.

[0059] For the water tank of an electric water heater, the tank generally consists of an outer shell and an inner tank, with an insulation layer between them. The outer shell is usually made of plastic to meet the requirements of aesthetic and diverse designs; the inner tank can be made of metal or plastic, depending on the needs.

[0060] In addition, the insulation layer formed between the outer shell and the inner liner is commonly made of materials such as asbestos, sponge, foam plastic, and polyurethane foam. In conventional technology, foaming is usually used to form the insulation layer in order to achieve good insulation effect.

[0061] For water tanks with metal inner liner, corrosion can easily occur inside due to water quality. Therefore, magnesium rods are installed on the water tank and inserted into the water storage cavity inside the tank.

[0062] Magnesium has the lowest electrochemical potential among metals and is physiologically non-toxic. Therefore, it is ideal for making magnesium rods to protect the inner liner. The size of the magnesium rod directly affects the duration and effectiveness of the protection; the larger the magnesium rod, the better the protection and the longer the protection time.

[0063] The water tank is also equipped with an inlet pipe and an outlet pipe. The inlet pipe is used to deliver cold water into the water storage cavity formed inside the water tank, while the hot water in the water storage cavity is output from the outlet pipe.

[0064] For electric heating components, electric heating methods such as electric heating wires, magnetic energy, or silicon tube heating can be used to heat the water stored in the water storage chamber.

[0065] The control board is used to receive detection signals from relevant sensors (such as water temperature sensors and flow sensors) and control the power supply to and from the electric heating components.

[0066] When the electric water heater is working, the electric control board controls the electric heating element to be powered on and heated. When the water temperature in the tank reaches the set value, the electric control board controls the electric heating element to be powered off.

[0067] like Figure 1 , Figure 2 , Figure 10 and Figure 11 As shown, one embodiment of this application provides an inner liner module, including:

[0068] The inner liner body 1 has a mounting part 11, the outer surface of the mounting part 11 forms an inclined mounting surface 110, and the inclined mounting surface 110 has mounting holes (not marked).

[0069] An electric heating element 3 is disposed on the inner liner body 1 and extends into the inner liner body 1;

[0070] Electronic anode 2, which is sealed in the mounting part 11, passes through the mounting hole of the mounting part 11 and extends into the inner liner body 1, and the electrode rod 25 of the electronic anode 2 is arranged above the electric heating tube 3;

[0071] The inclined mounting surface 110 is configured to support the electronic anode 2, which is inclinedly arranged in the inner liner body 1.

[0072] Specifically, in the actual assembly process, the electric heating tube 3 is installed and fixed on the inner liner body 1 using a conventional installation method, while the electronic anode 2 is installed on the inner liner body 1 through the mounting part 11.

[0073] For the mounting part 11, the outer surface of the mounting part 11 forms an inclined mounting surface 110. After the operator fixes the electronic anode 2 to the mounting part 11, the inclined mounting surface 110 is used to make the electronic anode 2 extend upwards at an overall angle. The electrode rod 25 is arranged at the top position of the inner liner body 1. In this way, the fixed installation position of the electronic anode 2 can be effectively reduced, so that the mounting part 11 does not need to be arranged in the upper area of ​​the inner liner body 1. The electrode rod 25 can be arranged in the top area of ​​the inner liner body 1 to the maximum extent, reducing the height installation restriction of the electronic anode 2. In this way, the electric heating tube 3 can be extended and arranged at a higher position in the inner liner body 1.

[0074] During use, after the electronic anode 2 is energized, the electrode rod 25 comes into contact with water for electro-corrosion protection. Hydrogen gas is generated during the operation of the electrode rod 25, and this hydrogen gas continuously accumulates in the inner liner 1. As the hydrogen gas increases, the water level in the inner liner 1 continuously decreases. When the water level in the inner liner 1 drops below the electrode rod 25, the electrode rod 25 is no longer in contact with the water, preventing it from being energized and thus stopping the electrolysis of the water in the inner liner 1 to produce hydrogen gas. At this time, the electric heating tube 3 remains below the liquid surface in the inner liner 1, and it does not come into contact with the hydrogen gas at the top of the inner liner 1, thus preventing a hydrogen explosion.

[0075] Meanwhile, the control board in the electric water heater can actively cut off the power to the electric heating tube 3 after detecting that the electronic anode 2 is de-energized (such as detecting the voltage across the electronic anode 2 or the current of the electronic anode 2), in order to further ensure safety during use.

[0076] In one embodiment, such as Figure 10 As shown, the mounting portion 11 is a protruding structure provided on the inner liner body, and the protruding structure is provided with the inclined mounting surface 110. Alternatively, as... Figure 11 As shown, the mounting part 11 is a recessed structure provided on the inner liner body 1, and the recessed structure is provided with the inclined mounting surface 110.

[0077] In some embodiments of this application, the inner liner body 1 includes a liner 10 and a flange 15, the flange 15 being disposed on the liner 10; the electric heating tube 3 is disposed on the flange 15.

[0078] Specifically, the electric heating element 3 can be installed and fixed by the flange 15 provided on the inner liner body 1. The flange 15 is fixedly installed at one end of the inner liner body 1, and the electric heating element 3 is installed on the flange 15.

[0079] In some embodiments, the mounting portion 11 may be located on the inner body 10. Alternatively, the mounting portion 11 may be located on the flange 15.

[0080] In some embodiments of this application, the electronic anode 2 includes an insulating member 24, a conductive member 26, and an electrode rod 25. The conductive member 26 and the electrode rod 25 are electrically connected. The insulating member 24 covers the connection portion between the conductive member 26 and the electrode rod 25, and at least a portion of the electrode rod 25 extends beyond the insulating member 24.

[0081] The insulating component 24 is sealed in the mounting portion 11, and the electrode rod 25, which is exposed outside the insulating component 24, is arranged above the electric heating tube 3.

[0082] Specifically, the insulating member 24 serves as a mounting support component, and both the conductive member 26 and the electrode rod 25 are disposed on the insulating member 24. Part of the electrode rod 25 is embedded within the insulating member 24 and electrically connected to the conductive member 26. During installation, the insulating member 24 is sealed and installed in the mounting portion 11.

[0083] In another embodiment of this application, such as Figure 1 As shown, the electric heating tube 3 includes a first heating tube 31, which extends to the bottom of the inner liner body 1;

[0084] The electrode rod 25, which is exposed outside the insulating member 24, is arranged above the first heating tube 31.

[0085] Specifically, in order to fully and effectively heat the water inside the inner tank 1, a first heating pipe 31 is provided. The first heating pipe 31 extends into the inner tank 1 and towards the bottom of the inner tank 1. The first heating pipe 31 can heat the water in the inner tank 1 from the bottom area of ​​the inner tank 1.

[0086] Furthermore, the inner liner body 1 is also provided with a water inlet pipe 16 and a water outlet pipe 17, with the water inlet end of the water outlet pipe 17 extending to the top of the inner liner body 1.

[0087] The electric heating tube 3 also includes a second heating tube 32, which extends to the inlet end of the water outlet pipe 17;

[0088] The electrode rod 25, which is exposed outside the insulating member 24, is arranged above the second heating tube 32.

[0089] Specifically, in order to meet the requirement of rapid hot water output, the electric heating tube 3 also includes a second heating tube 32. The second heating tube 32 extends into the inner tank body 1 and extends upward along the water outlet pipe 17. The second heating tube 32 can directly heat the water near the water inlet end of the water outlet pipe 17, so that the water in the inner tank body 1 near the water inlet end of the water outlet pipe 17 can be heated up quickly, so that the inner tank body 1 can output hot water quickly.

[0090] As for the electrode rod 25, it will be arranged above the highest part of the second heating tube 32 to meet the requirements of safe and reliable use.

[0091] There are various structural forms for assembling the insulating component 24 and the mounting part 11. Examples are given below with reference to the attached drawings.

[0092] In one embodiment, such as Figures 1-2 As shown, the outer wall of the insulating component 24 is provided with a positioning plate 241, the positioning plate 241 abuts against the inner surface of the mounting part 11, and the insulating component 24 extends through the mounting hole to the outside of the inner liner body 1 and is threadedly connected with a nut 242.

[0093] Specifically, during assembly, the electronic anode 2 is first fixedly installed on the flange 15, the insulating part 24 is inserted into the mounting hole from the inside of the flange 15, the positioning plate 241 is positioned against the inner surface of the mounting part 11, and the nut 242 is threaded onto the insulating part 24 and against the inclined mounting surface 110.

[0094] In one embodiment, such as Figures 3-5 As shown, the mounting hole of the mounting part 11 is provided with an internal thread, and the insulating member 24 is provided with an external thread. The insulating member 24 is threadedly connected to the mounting part 11.

[0095] Specifically, the insulating element 24 is inserted into the mounting part 11 and the external thread and internal thread are engaged, so that the insulating element 24 is threadedly connected in the mounting part 11, thereby fixing the electronic anode 2 in the mounting part 11.

[0096] In another embodiment, such as Figures 6-7 As shown, an installation tube 111 is provided on the inclined installation surface of the installation part 11. The installation tube 111 is perpendicular to the inclined installation surface 110. An insertion hole 12 is provided on the tube wall of the installation tube 111. A locking member 13 is provided in the insertion hole 12. The insulating member 24 is provided with a locking mating part 23.

[0097] The insulating component 24 is sealed and inserted into the mounting tube 111 and extends into the interior of the inner liner body 1 through the mounting hole, and the locking component 13 is connected to the locking mating part 23.

[0098] Specifically, the mounting portion 11 on the inner liner body 1 is also equipped with a mounting tube 111. Since the mounting tube 111 is perpendicular to the inclined mounting surface 110, the mounting tube 111 is arranged at an angle. The mounting tube 111 is used to install the electronic anode 2. The electronic anode 2 is inserted into the mounting tube 111, and the insulating part 24 of the electronic anode 2 is sealed inside the mounting tube 111. After the electronic anode 2 is inserted into place, the locking fitting portion 23 is aligned with the insertion hole 12 on the mounting portion 11, and the locking member 13 is inserted into the insertion hole 12 and connected to the locking fitting portion 23.

[0099] Under the locking action of the locking member 13, the insulating member 24 is locked in the mounting part 11, preventing the insulating member 24 from falling out of the mounting part 11.

[0100] Since the insulating member 24 is locked and limited by the locking member 13, there is no need to form an external thread on the insulating member 24 for threaded connection, thereby avoiding damage to the insulating member 24 due to excessive tightening force. The locking mating part 23 can be manifested as a groove, in which the locking member 13 is engaged.

[0101] Under the action of the locking member 13, the insulating member 24 is restricted in the mounting tube 111 and cannot move, so as to fix the insulating member 24 in the mounting tube 111. When it is necessary to remove the electronic anode 2, the locking member 13 is pulled out from the socket 12, and the insulating member 24 can be pulled out from the mounting tube 111.

[0102] Since the insulating component 24 is detachably and sealed within the installation pipe 111, during the extended use of the water heater in the user's home, there is a possibility that the electronic anode 2 may become damaged and require repair or replacement. Therefore, the insulating component 24 is detachably installed within the installation pipe 111. This allows the operator to remove the insulating component 24 from the installation pipe 111 and replace it with a new electronic anode 2 for continued use if the electronic anode 2 becomes damaged.

[0103] In one embodiment, a sealing ring 22 is provided on the outer periphery of the insulating member 24, and the sealing ring 22 is pressed between the inner wall of the mounting tube 111 and the insulating member 24;

[0104] The sealing ring 22 is arranged inside the locking mating part 23.

[0105] Specifically, an annular groove 21 is provided on the outer periphery of the insulating component 24, and a sealing ring 22 is provided on the annular groove 21. The sealing ring 22 is pressed against the inner wall of the mounting tube 111 to improve the installation sealing of the insulating component 24, so as to prevent water in the inner liner body 1 from leaking from the connection between the insulating component 24 and the mounting tube 111.

[0106] An annular groove 21 is provided on the insulating component 24 to position and install the sealing ring 22. After the insulating component 24 is inserted into the mounting tube 111, the sealing ring 22 will be pressed against the inner wall of the insulating component 24 and the mounting tube 111, so as to effectively seal the connection between the insulating component 24 and the mounting tube 111.

[0107] At the same time, in order to improve the sealing performance, multiple sealing rings 22 can be further fitted on the outside of the insulating component 24 to form multiple sealing areas through the multiple sealing rings 22.

[0108] In one embodiment, the locking member 13 has an overall U-shaped structure, with locking posts 131 formed at both ends of the locking member 13, and a connecting rod 132 formed in the middle of the locking member 13, the connecting rod 132 connecting the two locking posts 131.

[0109] The mounting tube 111 is provided with two insertion holes 12. The locking pin 131 is inserted into the corresponding insertion hole 12 and locked in the locking mating part 23. The insulating member 24 is located between the two locking pins 131.

[0110] Specifically, the locking member 13 has a U-shaped structure. After the insulating member 24 is inserted into the mounting tube 111, the locking post 131 of the locking member 13 is inserted into the corresponding side insertion hole 12, so that the insulating member 24 is more securely assembled into the mounting tube 111 by the locking post 131 on both sides cooperating with the locking mating part 23 of the insulating member 24.

[0111] In some embodiments, the mounting tube 111 is further provided with a receiving groove 14 on its wall, and the connecting rod 132 is located in the receiving groove 14.

[0112] Specifically, a receiving groove 14 is provided on the wall of the installation pipe 111 to accommodate the installation connecting rod 132.

[0113] In this way, after the insulating part 24 is locked in the mounting tube 111 by the locking part 13, the connecting rod 132 will be hidden in the receiving groove 14, which can prevent the locking part 13 from coming out of the socket 12 due to the operator accidentally touching the connecting rod 132 during the subsequent wiring process, thus improving the reliability of the assembly.

[0114] In another embodiment of this application, a water heater is also provided, including a housing and an inner tank module as described in the above embodiments; the inner tank module is disposed in the housing.

[0115] Compared with existing technologies, the advantages and positive effects of this utility model are as follows: the electrode rod of the electronic anode is arranged above the electric heating tube, ensuring that the hydrogen gas generated by the electronic anode will not come into contact with the electric heating tube exposed above the water surface, fundamentally avoiding the risk of explosion and meeting the core requirements for safe use. Simultaneously, by setting the installation channel of the mounting part to extend upwards and inclined towards the interior of the inner tank, the fixed installation part of the electronic anode does not need to be located at the top of the inner tank, provided that the electrode rod is positioned above the electric heating tube. Furthermore, it allows the electrode rod of the electronic anode to be as close as possible to the top of the inner tank, reserving more space for adjusting the installation height of the electric heating tube. The electric heating tube can also be arranged at a higher position within the inner tank, satisfying the height installation requirements of the electronic anode and increasing the installation range of the electric heating tube within the inner tank for this water heater.
