Description

Technical Field

[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 these, electric water heaters can be further divided into storage-type and instantaneous types based on their heating power. Storage-type electric water heaters, equipped with a water tank, offer advantages such as large water output and stable water temperature, making them more popular among families.

[0003] For conventional storage-type electric water heaters, a water tank is typically included for storing water. To improve the quality of the incoming and outgoing water, a filter pipe can be added to the inlet or outlet pipe to filter the flowing water. However, as the usage time increases, the filtration capacity of the filter pipe will gradually decrease or even become ineffective, at which point the filter pipe needs to be replaced.

[0004] In existing technologies, when the filter tube needs to be replaced, the entire inlet and outlet water pipes must be removed from the water tank, then the filter tube itself must be disassembled to replace it with a new one, and finally the inlet and outlet water pipes must be reinstalled in the water tank. This process of replacing the filter tube is cumbersome and inconvenient for maintenance. Therefore, how to design a technology that facilitates disassembly and replacement to improve maintenance convenience is the technical problem this invention aims to solve. Summary of the Invention

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] like Figures 1-8 As shown, this embodiment provides a water pipe assembly, including: Water treatment component 1, the water treatment component 1 being configured to treat water quality; Connecting seat 2, the connecting seat 2 having an installation channel 21, and the connecting seat 2 also having a first fixed installation part 22; Sleeve 3, the sleeve 3 is provided with a locking part 31, the sleeve 3 is disposed on the first fixed mounting part 22 and communicates with the mounting channel 21; The locking component 4 is provided with a locking engagement part 41 and a second fixed mounting part 42. The locking component 4 is disposed in the sleeve 3. The locking engagement part 41 is connected to the locking part 31. The water treatment component 1 is disposed on the second fixed part and extends to the outside of the sleeve 3.

[0046] Specifically, the water treatment component 1 has components for functionally treating water. Its physical form can be a functional device used in conventional water heaters, such as a magnesium rod, or a water treatment pipe filled with functional fillers (natural minerals, scale inhibitors). During use, the water treatment component 1 is placed inside the water tank to treat the water in the tank accordingly. The specific physical form of the water treatment component 1 is not limited or described in detail here.

[0047] As the usage time increases, the function of water treatment component 1 may weaken or fail, thus requiring replacement and maintenance of water treatment component 1.

[0048] The water pipe assembly provided in this application includes a water treatment component 1. Furthermore, to facilitate better maintenance of the water treatment component 1, the water treatment component 1 can be detachably installed into the water pipe assembly. This allows for convenient and quick removal of the water treatment component 1 from the water pipe assembly during later use when replacement or maintenance is required.

[0049] Specifically, in order to meet the requirements for installation on the water tank, the water pipe assembly is equipped with a connector 2, which is used to seal and fix the water pipe assembly on the water tank, thereby assembling the water pipe assembly onto the water tank.

[0050] To meet the requirements for disassembly and assembly of the water treatment component 1, a sleeve 3 is also provided on the connector 2. The sleeve 3 can extend into the interior of the water tank, and the sleeve 3 is connected to the installation channel 21 on the connector 2. In this way, the water treatment component 1 can be inserted into the sleeve 3 through the installation channel 21 to complete the installation, and the water treatment component 1 can also be disassembled and pulled out from the sleeve 3 through the installation channel 21.

[0051] To allow for detachable installation within the sleeve 3, the water treatment component 1 is housed in a locking component 4 and detachably assembled into the sleeve 3 via the locking component 4. Specifically, the locking component 4 is provided with a locking engagement part 41, which engages with a locking part 31 on the sleeve 3 to lock as needed, thereby fulfilling the requirement of fixing the water treatment component 1 within the sleeve 3. Simultaneously, when the locking engagement part 41 is unlocked from the locking part 31, the water treatment component 1 can be smoothly disassembled and pulled out of the sleeve 3, allowing for individual removal of the water treatment component 1 without disassembling the entire water tank assembly.

[0052] There are various structural entities that enable the locking engagement between the locking part 31 and the locking mating part 41 to allow the water treatment component 1 to be detachably installed. Examples are given below.

[0053] In one embodiment of this application, as Figure 6 and Figure 7As shown, the locking part 31 includes a first tooth structure 311 and a second tooth structure 312, which are arranged opposite to each other and are formed on the inner wall of the sleeve 3. The locking engagement part 41 includes a positioning rib, which is arranged on the outer wall of the locking component 4; The first tooth structure 311 is configured to engage with the positioning rib such that the locking member 4 rotates within the sleeve 3 to switch the positioning rib to selectively engage with the second tooth structure 312 in a locking relationship. The second tooth structure 312 is configured to cooperate with the positioning rib to prevent the locking member 4 from disengaging from the sleeve 3.

[0054] Specifically, a first tooth structure 311 and a second tooth structure 312 are formed on the inner wall of the sleeve 3. Correspondingly, a positioning rib is provided on the locking component 4. The positioning rib can slide up and down between the first tooth structure 311 and the second tooth structure 312. The first tooth structure 311 can cooperate with the upper end of the positioning rib so that the positioning rib rotates at a certain angle in the sleeve 3, thereby controlling the positioning rib to form a locking engagement with the second tooth structure 312, and switching the positioning rib and the second tooth structure 312 to unlock.

[0055] When the positioning rib and the second tooth structure 312 form a locking engagement, the water treatment component 1 will be installed and fixed on the sleeve 3; and when the positioning rib and the second tooth structure 312 are unlocked, the water treatment component 1 can be removed from the sleeve 3.

[0056] In some embodiments, the inner wall of the sleeve 3 is provided with a plurality of locking portions 31 arranged at intervals. The plurality of locking portions 31 are distributed around the axis of the sleeve 3, and a sliding guide groove 313 is formed between two adjacent locking portions 31. The sliding guide groove 313 extends along the axial direction of the sleeve 3.

[0057] Specifically, to improve installation reliability and ensure that the water treatment component 1 can be reliably installed on the sleeve 3 when the locking component 4 is in the locked state, multiple locking parts 31 can be provided in the sleeve 3. The multiple locking parts 31 are distributed around the axis of the sleeve 3. Correspondingly, the locking component 4 can also be arranged with multiple locking mating parts 41 in the circumferential direction to cooperate with the corresponding locking parts 31, so that the locking component 4 in the locked state can play a good role in fixing and installing the water treatment component 1.

[0058] In some embodiments, the first tooth structure 311 is formed with a first inclined surface 3111 and a second inclined surface 3112 arranged at intervals, the first inclined surface 3111 and the second inclined surface 3112 being distributed sequentially around the axis of the sleeve 3. The second tooth structure 312 is formed with a third inclined surface 3121 and a fourth inclined surface 3122 arranged at intervals, and the third inclined surface 3121 and the fourth inclined surface 3122 are distributed sequentially around the axis of the sleeve 3; Wherein, the projection of one end of the first inclined surface 3111 along the axial direction of the sleeve 3 is located outside the third inclined surface 3121, and the projection of the other end of the first inclined surface 3111 along the axial direction of the sleeve 3 is located on the third inclined surface 3121; the projection of one end of the second inclined surface 3112 along the axial direction of the sleeve 3 is located on the third inclined surface 3121, and the projection of the other end of the second inclined surface 3112 along the axial direction of the sleeve 3 is located on the fourth inclined surface 3122.

[0059] Specifically, the tooth surface distribution of the first tooth structure 311 and the second tooth structure 312 is designed accordingly. When the positioning rib moves to the first tooth structure 311 and engages with the first inclined surface 3111, the locking component 4 will rotate, causing the positioning rib to rotate above the third inclined surface 3121. Thus, as the locking component 4 moves towards the second tooth structure 312, the positioning rib will slide along the third inclined surface 3121, causing the locking component 4 to rotate by a certain angle. At this time, the positioning rib of the locking component 4 is locked to the second tooth structure 312, and the positioning rib will be arranged opposite to the second inclined surface 3112 of the first tooth structure 311.

[0060] When disassembly is required, the positioning rib moves toward the first tooth structure 311 again and drives the locking component 4 to rotate a certain angle via the second inclined surface 3112. Then, the positioning rib will be opposite to the fourth inclined surface 3122. At this time, the positioning rib moves toward the second tooth structure 312 again and is guided by the fourth inclined surface 3122, so that the positioning rib of the locking component 4 is disengaged from the second tooth structure 312 to achieve unlocking.

[0061] In some embodiments, the first tooth structure 311 is formed with a first guide surface 3113, which extends along the axial direction of the sleeve 3 and is located between the first inclined surface 3111 and the second inclined surface 3112. The second tooth structure 312 has a second guide surface 3123, which extends along the axial direction of the sleeve 3 and is located between the third inclined surface 3121 and the fourth inclined surface 3122. Wherein, the projection of the first guide surface 3113 along the axial direction of the sleeve 3 is located on the third inclined surface 3121; the projection of the second guide surface 3123 along the axial direction of the sleeve 3 is located on the second inclined surface 3112.

[0062] Specifically, the first guide surface 3113 guides the positioning rib to move toward the third inclined surface 3121 as it moves away from the first tooth structure 311. Similarly, the second guide surface 3123 guides the positioning rib to move toward the second inclined surface 3112 as it moves away from the second tooth structure 312. This ensures accurate locking and unlocking of the locking component 4, improving reliability.

[0063] In some embodiments, one end of the positioning rib is formed with a first mating inclined surface 411, which is configured to contact and engage with the first inclined surface 3111 or the second inclined surface 3112 to drive the locking member to rotate. The other end of the positioning rib has a second mating inclined surface 411, which is configured to contact and engage with the third inclined surface 3121 or the fourth inclined surface 3122 to drive the locking component to rotate.

[0064] Specifically, in order to enable the positioning rib to cooperate with the first tooth structure 311 and the second tooth structure 312 to drive the locking component 4 to rotate smoothly, a first mating inclined surface 411 and a second mating inclined surface 411 can be respectively provided at both ends of the positioning rib. The inclination angle of the first mating inclined surface 411 and the second mating inclined surface 411 will match the mating inclined surface, so that the positioning rib can rotate smoothly after contacting the inclined surface of the corresponding tooth structure.

[0065] In another embodiment, the sleeve 3 is provided with an elastic element 32, which is configured to apply a spring force to the locking member 4 toward the connecting seat 2.

[0066] Specifically, an elastic element 32 is provided in the sleeve 3, which applies a spring force to the locking component 4 to facilitate operation. In actual use, the operator only needs to apply a pushing force to the locking component 4 in the sleeve 3 from the outside to make the locking component 4 move toward the first tooth structure 311, and the reset of the locking component 4 is achieved by applying a reset force through the elastic element 32.

[0067] The elastic element 32 is a spring, and the end of the sleeve 3 away from the connecting seat 2 is provided with a positioning part, and the spring is clamped between the positioning part and the locking component 4.

[0068] Specifically, a spring is used to fit the locking component 4, and the spring will apply a spring force to the locking component 4 in the direction of the second tooth structure 312. A positioning ring 35 is provided at the end of the sleeve 3 so that the spring is pressed between the positioning ring 35 and the locking component 4, and the water treatment component 1 can extend through the positioning ring 35 to the outside of the sleeve 3.

[0069] In some embodiments, the first fixed mounting portion 22 is a first internal threaded hole formed in the inner wall of the mounting channel 21; the end of the sleeve 3 is provided with a plurality of extension portions 33, the plurality of extension portions 33 are distributed around the axis of the sleeve 3, an auxiliary guide groove 34 is formed between two adjacent extension portions 33, the auxiliary guide groove 34 is connected to the corresponding sliding guide groove 313, and the outer wall of the extension portion 33 is provided with a first external threaded section; the first external threaded section is threadedly connected in the first internal threaded hole.

[0070] Specifically, the sleeve 3 can be fixedly installed on the connecting seat 2 by means of threaded connection, and the first external thread segment formed on the sleeve 3 can meet the requirements of threaded fixed connection; at the same time, the auxiliary guide groove 34 formed between the adjacent extensions 33 will communicate with the corresponding sliding guide groove 313 formed in the sleeve 3, so as to guide the positioning rib through the cooperation of the auxiliary guide groove 34 and the sliding guide groove 313 during the disassembly and assembly of the locking component 4.

[0071] In another embodiment of this application, the locking part 31 and the locking mating part 41 can be structurally represented by a threaded connection. Specifically, in one embodiment, the locking part 31 is a second internal threaded hole formed on the inner wall of the sleeve 3, and the locking mating part 41 is a second external threaded segment formed on the outer wall of the locking component 4, the second external threaded segment being threadedly connected to the second internal threaded hole. Specifically, during use, the locking component 4 is screwed to achieve assembly and disassembly with the sleeve 3.

[0072] Alternatively, in another embodiment, the locking part 31 and the locking mating part 41 can be structurally represented by a snap-fit ​​mechanism. Specifically, the locking part 31 is a positioning groove formed on the inner wall of the sleeve 3, and the locking mating part 41 is an elastic protrusion formed on the outer wall of the locking component 4, with the elastic protrusion engaging in the positioning groove. Specifically, during use, the locking component 4 is pushed into the sleeve 3 to deform the elastic protrusion and engage it in the positioning groove, thus achieving assembly. When disassembly is required, the locking component 4 can be clamped with pliers and pulled outwards to disengage the elastic protrusion from the positioning groove.

[0073] In one embodiment of this application, the first fixed mounting part 22 is a fixed insertion hole communicating with the mounting channel 21, and the sleeve 3 is inserted into the fixed insertion hole.

[0074] Specifically, the sleeve 3 can be inserted into the fixed socket to be installed on the connector 2.

[0075] In one embodiment of this application, the second fixed mounting part 42 is a slot formed on the locking member 4, and the water treatment member 1 is inserted into the slot.

[0076] Specifically, the water treatment component 1 is inserted into the slot to achieve installation on the locking component 4.

[0077] Alternatively, the second fixed mounting part 42 is a threaded groove formed on the locking member 4, and the water treatment member 1 is threadedly connected in the threaded groove.

[0078] Specifically, the water treatment component 1 is fixedly connected to the locking component 4 by a threaded connection.

[0079] In one embodiment of this application, the water treatment component 1 may be a magnesium rod.

[0080] Alternatively, the water treatment component 1 may be a water treatment pipe, in which functional filler is provided and several through holes are provided.

[0081] Specifically, for water treatment component 1, when functional fillers are required to perform corresponding functional treatments on the water, a water treatment pipe can be used to install the functional fillers to meet the installation requirements. The water treatment pipe has through holes to allow water to enter the pipe and contact the functional fillers, thereby treating the water in the tank. The functional fillers are natural minerals and scale inhibitors.

[0082] In one embodiment of this application, the side wall of the connecting seat 2 is further provided with a drainage connection hole 23, which communicates with the installation channel 21.

[0083] Specifically, for the water pipe assembly, to enrich its functionality, a drain connection hole 23 can be provided on the connector 2. During use, when it is necessary to drain the water in the water tank, the water in the water tank can be discharged outward through the drain connection hole 23 located at the bottom, thereby realizing the function of draining.

[0084] Meanwhile, a valve 24 is also provided at the end of the connecting seat 2 away from the sleeve 3.
