Description

Technical Field

[0001] This utility model belongs to the field of household appliance technology, and in particular relates to a horizontal and vertical universal water heater. Background Technology

[0002] Currently, water heaters are common household appliances, categorized into electric water heaters, heat pump water heaters, and solar water heaters. Electric water heaters are widely used due to their convenience. Among them, storage-type electric water heaters, equipped with a water tank, offer advantages such as large water output and stable water temperature, making them increasingly popular with families.

[0003] Chinese Patent Publication No. CN116447748A discloses a water heater suitable for both vertical and horizontal installation and its control method. The water heater can be installed vertically or horizontally according to the user's home installation requirements. Since the water heater needs to store water, anti-corrosion treatment is usually performed to protect the inner tank and slow down corrosion. Conventional methods include adding a magnesium rod or an external electron anode to the inner tank.

[0004] During use, because the water tank can be installed vertically or horizontally, when the inner tank is low on water, the electric heating element can easily protrude above the water surface. Furthermore, the electronic anode continuously produces hydrogen gas during operation. This hydrogen gas accumulates at the top of the inner tank, and when the electric heating element is exposed above the water surface, the high temperature of the element can cause a hydrogen evolution explosion, reducing the safety and reliability of the water heater. Therefore, how to design a technology to improve the safety and reliability of water heaters is the technical problem this invention aims to solve. Utility Model Content

[0005] This utility model provides a universal water heater that can be used both horizontally and vertically, thereby improving the safety and reliability of water heaters.

[0018] The first tank is provided with a water outlet pipe, which extends into the first tank and is arranged away from the second tank, and the water outlet pipe extends along the length of the first tank.

[0019] The second tank is provided with a water inlet pipe, which extends into the second tank and is located away from the first tank. The water inlet pipe extends along the length of the second tank; the length of the water inlet pipe is less than the length of the water outlet pipe.

[0020] In one embodiment of this application, a fixed connection portion is provided at the first end of the insulating mounting base, and the fixed connection portion is configured to seal the insulating mounting base on the inner liner.

[0021] A first sealing ring is also fitted onto the first end of the insulating mounting base, and the first sealing ring is configured to seal the connection between the conductive rod and the first end of the insulating mounting base.

[0022] In one embodiment of this application, the conductive rod extending to the outer end of the insulating mounting base is further provided with a first threaded section, and a locking nut is provided on the first threaded section. The locking nut is configured to deform the first sealing ring in the tightened state to seal the connection between the conductive rod and the first end of the insulating mounting base.

[0023] In one embodiment of this application, the end face of the first end of the insulating mounting base is provided with an annular groove, the annular groove is arranged around the outer periphery of the conductive rod, and the first sealing ring is located in the annular groove;

[0024] The locking nut presses the first sealing ring into the annular groove.

[0025] In one embodiment of this application, a washer is further fitted on the first threaded section, and the edge of the washer is provided with a flange structure. The locking nut presses the washer against the end face of the first end of the insulating mounting base. The first sealing ring is pressed between the end face of the first end of the insulating mounting base and the washer, and the flange structure is wrapped around the outside of the first sealing ring.

[0026] In one embodiment of this application, the conductive rod extending to the outer end of the insulating mounting base is further provided with a wiring terminal.

Similarly, when the outer shell is installed vertically, the electrode rod can also be positioned above the electric heating element. Thus, in actual use, when the inner tank is low, because the electrode rod is not restricted by the installation method and is always positioned above the electric heating element, it ensures that the electronic anode stops electrolyzing and producing hydrogen gas as soon as the water level drops below the electrode rod, thereby improving the safety and reliability of the water heater. Furthermore, since the height of the electric heating element is never higher than the lowest point of the electrode rod, it ensures that the electric heating element will not continue to be energized after it emerges from the water surface, further improving safety and reliability.

[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] Example 1, as Figures 1-4 As shown, one embodiment of this application provides a water heater, including:

[0068] A water tank, the water tank comprising an outer shell 1 and an inner liner 2, the inner liner 2 being disposed within the outer shell 1;

[0069] An electric heating element 3 is disposed on the inner liner 2 and extends into the inner liner 2, and is configured to heat the water in the inner liner 2;

[0070] An electronic anode 5 includes an electrode rod 51, a conductive rod 52, and an insulating mounting base 53. The electrode rod 51 is electrically connected to the conductive rod 52. The insulating mounting base 53 is formed on the electrode rod 51 and the conductive rod 52. The connection portion of the electrode rod 51 and the conductive rod 52 is enclosed within the insulating mounting base 53. The conductive rod 52 extends to the outside of the first end of the insulating mounting base 53, and the electrode rod 51 extends to the outside of the second end of the insulating mounting base 53. The insulating mounting base 53 is disposed on the inner liner 2, and the first end extends into the inner liner 2.

[0071] In the case where the outer casing 1 is in a horizontal position, the electronic anode 5 is arranged above the electric heating element 3; in the case where the outer casing 1 is in an upright position, the portion of the electrode rod 51 extending beyond the first end is arranged above the electric heating element 3.

[0072] Specifically, in this embodiment, an electronic anode 5 is provided on the inner liner 2. The electronic anode 5 is sealed and fixedly installed on the inner liner 2 by an insulating mounting base 53. The first end of the insulating mounting base 53 extends into the inner liner 2, and the portion of the electrode rod 51 extending beyond the first end is also located inside the inner liner 2. In this way, when the electronic anode 5 is energized, the electrode rod 51 and the inner liner 2 conduct electricity through the stored water, thereby achieving current-based corrosion protection.

[0073] For water heaters, in order to meet the requirement of universal horizontal and vertical installation, it is necessary to avoid hydrogen evolution explosion for both the electronic anode 5 and the electric heating element 3 in both horizontal and vertical installation states. Therefore, the electric heating element 3 needs to be arranged below the electrode rod 51 in both vertical and horizontal installation states of the water heater.

[0074] refer to Figure 1 and Figure 2 As shown, when the outer casing 1 is in an upright state, the portion of the electrode rod 51 extending beyond the first end is arranged above the electric heating element 3.

[0075] Specifically, with the outer shell 1 in an upright position, the electronic anode 5 and the electric heating element 3 in the inner liner 2 are arranged vertically, with the portion of the electrode rod 51 protruding from the insulating mounting base 53 positioned above the electric heating element 3. During use, when the water level in the inner liner 2 drops below the electronic anode 5, the electrode rod 51 in the electronic anode 5 is exposed above the water surface, preventing electrical connection between the electrode rod 51 and the inner liner 2. This prevents the electrode rod 51 from releasing electrons for current-based corrosion protection, and also prevents hydrogen evolution in the inner liner 2 due to the electronic anode 5. This avoids the continuous generation of hydrogen gas in the inner liner 2, reducing the hydrogen concentration and thus lowering the possibility of a hydrogen evolution explosion.

[0076] At the same time, since the exposed electrode rod 51 is arranged above the electric heating element 3, when the electrode rod 51 cannot form an electric circuit with the inner tank 2 through the water stored in the inner tank 2, the controller (such as a microcontroller or CPU) configured in the water heater can simultaneously cut off the power to the electric heating element 3 when the electric circuit where the electronic anode 5 is located is disconnected.

[0077] refer to Figure 3 and Figure 4 As shown, when the outer casing 1 is in a horizontal position, the electronic anode 5 is arranged above the electric heating element 3.

[0078] Specifically, the outer shell 1 is in a horizontal position, and the electronic anode 5 and the electric heating element 3 in the inner liner 2 are arranged horizontally, with the electronic anode 5 positioned above the electric heating element 3. During use, when the water level in the inner liner 2 drops below the electronic anode 5, the electrode rod 51 of the electronic anode 5 is exposed above the water surface, preventing the electrode rod 51 from forming an electrical connection with the inner liner 2. This prevents the electrode rod 51 from releasing electrons for current-based corrosion protection, and also prevents hydrogen evolution in the inner liner 2 due to the electronic anode 5. This avoids the continuous generation of hydrogen gas in the inner liner 2, reducing the hydrogen concentration and thus lowering the possibility of a hydrogen evolution explosion.

[0079] At the same time, since the electronic anode 5 is arranged above the electric heating element 3, when the electronic anode 5 cannot form an electric circuit with the inner tank 2 through the water stored in the inner tank 2, the controller (such as a microcontroller or CPU) configured in the water heater can simultaneously cut off the power to the electric heating element 3 when the electric circuit where the electronic anode 5 is located is disconnected.

[0080] In one embodiment, the electronic anode 5 is configured to trigger the electric heating element 3 to de-energize when there is no water conducting between the electrode rod 51 and the inner liner 2.

[0081] Specifically, as the water level in the inner tank 2 decreases, the electrode rod 51 will eventually emerge from the water in the inner tank 2. At this point, the electrical circuit formed between the electrode rod 51 and the inner tank 2 will be broken. The water heater controller will automatically trigger the electric heating element 3 to cut off power after the electrical circuit between the electronic anode 5 and the inner tank 2 is broken. In this way, as the water level in the inner tank 2 continues to decrease, once the electric heating element 3 emerges from the water, it will be in a de-energized state. Even if there is a certain amount of hydrogen gas in the inner tank 2, the hydrogen gas will not reach an explosive temperature due to the electric heating element 3 being powered on, thus improving safety.

[0082] In one embodiment, in order to facilitate the installation of the electronic anode 5 and the electric heating element 3, a flange 23 is provided on the inner liner 2, and the electric heating element 3 and the electronic anode 5 are disposed on the flange 23.

[0083] Specifically, flange 23 is sealed and fixedly installed at the end of inner tank 2, and electronic anode 5 and electric heating element 3 are installed using flange 23. In the actual assembly process, electronic anode 5 and electric heating element 3 are pre-fixed on flange 23, and then electronic anode 5 and electric heating element 3 are uniformly fixed and assembled onto inner tank 2 through flange 23. In this way, the overall assembly efficiency of water heater can be effectively improved, and modular assembly production can be realized.

[0084] In one embodiment, a magnesium rod 4 is also included, which extends into the inner liner 2.

[0085] Specifically, in order to further improve the corrosion resistance of the water heater, a magnesium rod 4 can be installed in the inner tank 2. The magnesium rod 4 can continue to provide corrosion protection for the inner tank 2 when the water heater is powered off, thereby improving the protective performance of the inner tank 2 of the water heater.

[0086] Furthermore, to facilitate the uniform installation of the magnesium rod 4, a flange 23 is provided on the inner liner 2, and the electric heating element 3, the electronic anode 5 and the magnesium rod 4 are disposed on the flange 23.

[0087] In one embodiment, the outer shell 1 is provided with two inner liner 2 arranged side by side; the two inner liner 2 are divided into a first liner 21 and a second liner 22;

[0088] The first tank body 21 is provided with a water outlet pipe 24, which extends into the first tank body 21 and is arranged away from the second tank body 22. The water outlet pipe 24 extends along the length direction of the first tank body 21.

[0089] The second tank 22 is provided with a water inlet pipe 25, which extends into the second tank 22 and is arranged away from the first tank 21. The water inlet pipe 25 extends along the length direction of the second tank 22. The length of the water inlet pipe 25 is less than the length of the water outlet pipe 24.

[0090] Specifically, the water heater adopts a dual-tank design, which can effectively increase the water storage capacity. At the same time, each inner tank 2 is equipped with an independent electric heating element 3 and an electronic anode 5, so as to ensure that each inner tank 2 can obtain good anti-corrosion protection.

[0091] When installed horizontally, the first tank 21 will be positioned above the second tank 22, thus ensuring the hot water output rate of the water heater.

[0092] Example 2: Based on Example 1 above, the electronic anode is structurally improved as follows, such as... Figures 5-11 As shown, for the electronic anode 5, the first end of the insulating mounting base 53 is provided with a fixed connection portion 531, which is configured to seal the insulating mounting base 53 onto the inner liner 42; the insulating mounting base 53 is formed on the electrode rod 51 and the conductive rod 52, and the connection portion of the electrode rod 51 and the conductive rod 52 is wrapped inside the insulating mounting base 53; the conductive rod 52 extends to the outside of the first end of the insulating mounting base 53, and the electrode rod 51 extends to the outside of the second end of the insulating mounting base 53; a first sealing ring 54 is also fitted on the first end of the insulating mounting base 53, which is configured to seal the connection portion between the conductive rod and the first end of the insulating mounting base 53.

[0093] Specifically, the electronic anode 5 is fixedly mounted on the inner tank 42 via an insulating mounting base 53 during use. During use, because part of the insulating mounting base 53 extends into the inner tank 42, it will expand and contract due to temperature changes in the water within the inner tank 42.

[0094] Due to thermal expansion and contraction of the insulating mounting base 53, gaps will form between the insulating mounting base 53 and the electrode rod 51 and the conductive rod 52 after prolonged use, which will cause water in the inner liner 42 to leak from the electronic anode 5 through the gaps.

[0095] By adding a first sealing ring 54 at the connection between the first end of the insulating mounting base 53 and the conductive rod 52, the first sealing ring 54 effectively seals the connection between the insulating mounting base 53 and the conductive rod 52 from the outside. Thus, even if gaps are formed between the insulating mounting base 53 and the electrode rod 51 and the conductive rod 52, the water in the inner liner 42 will be sealed and blocked at the first end of the insulating mounting base 53 by the first sealing ring 54 when it flows out through the gaps, thereby effectively improving the sealing performance of the electronic anode 5.

[0096] In one embodiment, the conductive rod 52 extending to the outer end of the insulating mounting base 53 is further provided with a first threaded section 521, and a locking nut 55 is provided on the first threaded section 521. The locking nut 55 is configured to deform the first sealing ring 54 in the tightened state to seal the connection between the conductive rod and the first end of the insulating mounting base 53.

[0097] Specifically, in order to press and seal the connection between the first sealing ring 54 and the first end of the insulating mounting base 53, a locking nut 55 is provided on the conductive rod 52. After tightening the locking nut 55, the first sealing ring 54 will be pressed against the insulating mounting base 53 to achieve a good sealing effect.

[0098] In some embodiments, such as Figures 5-7 As shown, the end face of the first end of the insulating mounting base 53 is provided with an annular groove 532, the annular groove 532 is arranged around the outer periphery of the conductive rod 52, and the first sealing ring 54 is located in the annular groove 532.

[0099] The locking nut 55 presses the first sealing ring 54 into the annular groove 532.

[0100] Specifically, in order to facilitate the installation and positioning of the first sealing ring 54, an annular groove 532 can be provided on the end face of the first end of the insulating mounting base 53. During assembly, the first sealing ring 54 is placed into the annular groove 532, and then the locking nut 55 is tightened so that the first sealing ring 54 is squeezed into the annular groove 532.

[0101] In some embodiments, such as Figures 8-1 As shown, a washer 56 is also fitted on the first threaded section 521. The edge of the washer 56 is provided with a flange structure (not marked). The locking nut 55 presses the washer 56 against the end face of the first end of the insulating mounting base 53. The first sealing ring 54 is pressed between the end face of the first end of the insulating mounting base 53 and the washer 56. The flange structure is wrapped around the outside of the first sealing ring 54.

[0102] Specifically, in order to facilitate the installation and positioning of the first sealing ring 54, a washer 56 can be fitted on the outer end of the conductive rod 52. The washer 56 presses the first sealing ring 54 against the end face of the first end of the insulating mounting base 53, and the first sealing ring 54 is protected by the flange structure of the washer 56.

[0103] In another embodiment, to facilitate the power supply connection of the electronic anode 5, a terminal block 57 is provided on the outer end of the conductive rod 52 extending to the insulating mounting base 53.

[0104] Specifically, terminal 57 is mounted on conductive rod 52, and terminal 57 is electrically connected to power supply module via guide.

[0105] In some embodiments, the outer surface of the conductive rod 52 is provided with a plurality of annular ribs 522 arranged side by side, and the annular ribs 522 are located inside the insulating mounting base 53.

[0106] Specifically, the ring-shaped ribs can increase the contact area between the conductive rod 52 and the insulating mounting base 53, thereby increasing the flow path of water leakage when a gap occurs between them, which is more conducive to improving the reliability of use.

[0107] In other embodiments, the outer surface of the conductive rod 52 is provided with a plurality of annular grooves 523 arranged side by side, the annular grooves 523 being located within the insulating mounting base 53.

[0108] Specifically, the annular groove increases the contact area between the conductive rod 52 and the insulating mounting base 53, thereby increasing the flow path of water leakage when a gap occurs between them, which is more conducive to improving the reliability of use.

[0109] In another embodiment, a second sealing ring 58 is provided on the fixed connection portion 531, and the second sealing ring 58 is configured to seal the connection between the insulating mounting base 53 and the inner liner 42.

[0110] Specifically, the second sealing ring 58 is used to seal the connection between the insulating mounting base 53 and the inner liner 42 to meet the installation requirements of sealing the electronic anode 5 onto the inner liner 42.

[0111] In one embodiment, the fixed connection portion 531 includes a sealing portion 5311 and a second threaded section 5312. The outer circumferential dimension of the sealing portion 5311 is larger than the outer circumferential dimension of the second threaded section 5312, and the second sealing ring 58 is attached to the sealing portion 5311.

[0112] Specifically, the insulating mounting base 53 is threaded onto the inner liner 42 via the second threaded section 5312, and the second sealing ring 58 is sandwiched between the inner liner 42 and the sealing part 5311 to ensure that the second sealing ring 58 can provide a good seal.

[0113] By adding a first sealing ring at the connection between the first end of the insulating mounting base and the conductive rod, the connection between the insulating mounting base and the conductive rod is effectively sealed from the outside. Even if gaps occur between the insulating mounting base and the electrode rod and the conductive rod, the water in the inner tank will be sealed and blocked at the first end of the insulating mounting base when it flows out through the gaps. This effectively improves the sealing performance of the electronic anode and enhances the reliability of the water heater.
