Description

Technical Field

[0001] This utility model relates to the field of household appliances, and in particular to a filter scale inhibition device, a filter scale inhibition water circuit system, and a dishwasher. Background Technology

[0002] In existing technologies, dishwasher water softeners include structures such as a brine chamber, a resin chamber, and a solenoid valve to control water flow direction. This makes the internal structure of the dishwasher redundant and complex. On the one hand, this not only increases production costs but also occupies valuable internal space, limiting the possibility of functional expansion and hindering the improvement of the dishwasher's overall performance and competitiveness. On the other hand, the resin regeneration process requires the discharge of high-concentration brine, which has a significant environmental impact. Furthermore, after resin regeneration is complete, additional cleaning water is needed to rinse the resin to remove the brine, resulting in water waste. Utility Model Content

[0003] Therefore, it is necessary to address the issues of complex soft water structures in dishwashers and the environmentally unfriendly nature of resin regeneration in soft water structures by providing a scale-inhibiting filter device, a scale-inhibiting water circuit system, and a dishwasher.

[0004] A scale-inhibiting filter for a dishwasher includes: a housing assembly having a receiving cavity, the housing assembly having a housing inlet and a housing outlet communicating with the receiving cavity; a filter element disposed on the housing assembly and located within the receiving cavity, the filter element having a processing cavity, and a transition cavity forming between the filter element and the cavity wall of the receiving cavity; and a scale-inhibiting assembly having at least a portion located within the processing cavity, the housing inlet, the processing cavity, the transition cavity, and the housing outlet being sequentially connected.

[0005] The above-disclosed dishwasher filtration and scale inhibition device exhibits significant advantages in its innovative structural design compared to traditional filtration and scale inhibition devices. Both the filter element and the scale inhibition component are cleverly housed within the housing assembly's receiving cavity, a layout that greatly reduces the device's size. Traditional filtration and scale inhibition devices often contain multiple independent cavities such as a brine chamber and a resin chamber, resulting in a large overall size and occupying considerable space. This device, however, requires only a single filtration and scale inhibition receiving cavity, greatly saving installation space and making it easier to use in various space-constrained environments. Simultaneously, this device achieves effective functional expansion. It not only has scale inhibition capabilities but also adds the function of filtering impurities from tap water. By intercepting impurities in the water through the filter element, it effectively purifies the water quality and reduces the damage of impurities to subsequent water-using equipment. Furthermore, by omitting the brine chamber and resin chamber, the device's structure becomes simpler, and the number of parts is significantly reduced. This not only reduces manufacturing costs but also makes assembly, maintenance, and repair of the device more convenient. Fewer parts mean a lower failure rate, improving the device's stability and reliability. In addition, the pressure relief valve provides reliable safety assurance for the device. The scale inhibitor component is placed inside the treatment chamber, allowing it to fully contact the flowing water. When water enters the treatment chamber from the inlet of the housing, the scale inhibitor component effectively intercepts and adsorbs calcium and magnesium ions in the water, preventing scale formation. Simultaneously, in conjunction with the filter element within the treatment chamber, it filters out impurities such as sediment and rust from the water, achieving a dual function of impurity interception and scale inhibition. This improves water purification efficiency and ensures the normal operation of subsequent water-using equipment.

[0006] In one embodiment, the housing assembly includes a main housing and a top cover. The top cover is disposed on the main housing, and the top cover and the main housing enclose the receiving cavity. One end of the filter element is disposed on the housing assembly, and a portion of the scale inhibitor assembly is sandwiched between the top cover and the other end of the filter element. By utilizing the receiving cavity formed by the top cover and the main housing, the filter element and the scale inhibitor assembly are integrated in an orderly manner, making the entire device structure compact. Compared to a distributed layout, this design significantly reduces the space occupied by the device, saving installation space and facilitating integration into various water-using equipment or systems, thus improving space utilization efficiency. One end of the filter element is firmly disposed on the housing assembly, and the scale inhibitor assembly is partially sandwiched between the top cover and the filter element, ensuring that both are fixed in position under the impact of water flow and will not shift or shake. This allows water to flow stably through the filter element and the scale inhibitor assembly, fully utilizing the impurity filtration function of the filter element and the scale prevention function of the scale inhibitor assembly, ensuring the stability and continuity of water purification effect.

[0007] In one embodiment, the housing assembly further includes an annular housing that extends toward the top cover and is fitted to the filter element at one end of the housing assembly; the top cover is detachable from the main housing. By tightly fitting the annular housing to the filter element, the filter element is supported and fixed, effectively preventing displacement or shaking under water flow impact, ensuring stable operation. Furthermore, the annular housing, main housing, and top cover together form a robust frame, enhancing the overall structural strength and stability, and improving the device's durability. Simultaneously, the annular housing extending toward the top cover and fitting to the filter element at one end of the housing assembly strengthens the filtration process. Before entering the filter element, the water flow undergoes initial buffering and distribution within the annular space, allowing for more even water flow through the filter element, significantly improving filtration efficiency and ensuring more thorough impurity interception. Moreover, the annular housing does not increase the difficulty of disassembly during later maintenance. When opening the top cover to replace the filter element, the annular housing not only does not obstruct the process, but also facilitates the replacement of the filter element with the scale-inhibiting device, maintaining the device's advantage of easy maintenance and providing users with an efficient and worry-free experience. By detaching the top cover from the main housing, when the filter element in the scale-inhibiting device becomes clogged, its filtration efficiency decreases, or the scale-inhibiting components in the scale-inhibiting assembly fail, the internal filter element and scale-inhibiting assembly can be directly accessed by removing the top cover, allowing for quick replacement. This eliminates the need for complex disassembly of the entire device, reducing maintenance difficulty and time costs, and ensuring continuous and efficient operation.

[0008] In one embodiment, the scale inhibition assembly includes a housing and scale inhibitors. A portion of the housing is sandwiched between the housing assembly and the filter element. The housing extends into the treatment chamber and has a recess. The scale inhibitor is disposed on the housing and located within the recess. By cleverly sandwiching the housing between the housing assembly and the filter element, and providing a recess, multiple scale inhibitors are arranged in an orderly manner. The numerous scale inhibitors work together, greatly expanding the contact area with the water flow, fully utilizing their scale inhibition effect, and efficiently intervening in ions that easily form scale in the water. Compared to a single scale inhibitor, this significantly improves scale inhibition capacity, effectively reducing scale deposition in pipes and water-using equipment, and extending equipment lifespan. The housing design makes the installation of the entire scale inhibition assembly more stable and convenient. During later maintenance, if it is necessary to inspect or replace the scale inhibitors, only the top cover needs to be opened, the housing removed, and the internal scale inhibitors can be operated on without large-scale disassembly of the entire device structure, greatly saving maintenance time and labor costs. Furthermore, the configuration of multiple scale inhibitors ensures that even after some scale inhibitors are worn out, others can still maintain a certain scale inhibition performance, guaranteeing the continuous and stable operation of the device during the maintenance cycle. This provides users with a more reliable and efficient scale inhibition experience, comprehensively improving water quality.

[0009] In one embodiment, the housing includes a top housing and a main housing. The top housing is sandwiched between the housing assembly and the filter element. The main housing is disposed on the top housing and located within the treatment chamber, extending along the length of the treatment chamber. The scale inhibitor is disposed on the main housing, which has the designated cavity. By precisely sandwiching the top housing between the housing assembly and the filter element, this arrangement ensures the entire scale inhibitor assembly is securely installed, preventing displacement under water flow impact and thus maintaining the scale inhibition effect. The main housing, disposed on the top housing and extending along the length of the treatment chamber, cleverly utilizes the internal space. Multiple scale inhibitors are evenly distributed on the main housing, which also has a designated cavity. This structural design allows water to fully contact each scale inhibitor as it flows through the treatment chamber. The extended layout of the main housing expands the interaction range between the water flow and the scale inhibitors, significantly improving scale inhibition efficiency, effectively reducing the possibility of scale formation in the water, providing comprehensive protection for pipes and water-using equipment from scale buildup, and extending their service life. When it is necessary to inspect or replace the scale inhibitor components, simply open the top cover to easily remove the mounting top shell and its connected main shell, eliminating the need for complicated operations and greatly saving maintenance time and labor costs. Even when some scale inhibitor components are damaged, others can still function normally, maintaining the scale inhibition performance of the device and ensuring the stability of water quality.

[0010] In one embodiment, an inner tank bottom plate is also included. The housing assembly further includes a fixing member and a sealing member, which are disposed on the main housing. A portion of the inner tank bottom plate is sandwiched between the fixing member and the sealing member. By placing the fixing member and the sealing member on the main housing, stable support is provided for the inner tank bottom plate. The fixing member ensures that the inner tank bottom plate is firmly installed and will not shift even under continuous water flow impact, ensuring the stability of the internal structure of the device. The sealing member provides a good sealing effect, effectively preventing water leakage, maintaining the normal operation of the device, and avoiding damage to the surrounding environment or device malfunction due to water leakage. The inner tank bottom plate is installed between the sealing members, not only participating in the construction of a stable internal structure, but also working in conjunction with the fixing member and the sealing member during maintenance, facilitating overall disassembly and inspection, greatly improving maintenance efficiency, and comprehensively ensuring the reliability and durability of the device.

[0011] The second aspect of this application discloses a scale-inhibiting water circuit system, which includes: the scale-inhibiting device of the dishwasher described above; a water inlet valve, which has a water inlet and a water outlet; a breather, which has a breather inlet and a breather outlet; and a cup body, which has a cup body inlet; wherein the water inlet valve, the breather, the scale-inhibiting device of the dishwasher, and the cup body are arranged in sequence.

[0012] The second aspect disclosed above discloses a filtration and scale-inhibiting water system. The filtration and scale-inhibiting device, with its unique structure, effectively filters impurities and prevents scale formation. The inlet valve precisely controls the water flow, ensuring a stable water supply, and its rational inlet and outlet design makes water distribution more scientific. The breather balances the pressure inside and outside the system, preventing negative pressure and ensuring smooth water flow, avoiding air backflow and water quality contamination. The cup body is used to collect the purified water, providing users with a convenient way to obtain water. The entire system works in synergy, comprehensively ensuring the safety, cleanliness, and convenience of water use, greatly enhancing the user's water experience.

[0013] In one embodiment, the housing assembly is provided with a pressure relief chamber, and the housing inlet, the pressure relief chamber, the transition chamber, and the housing outlet are sequentially connected. It also includes a pressure relief valve, which is disposed on the housing assembly and located within the pressure relief chamber. The pressure relief valve can open or close the pressure relief chamber. When the pressure relief valve closes the pressure relief chamber, the inlet of the water inlet valve, the outlet of the water inlet valve, the inlet of the breather, the outlet of the breather, the housing inlet, the processing chamber, the transition chamber, the housing outlet, and the cup inlet are sequentially connected. When the pressure relief valve opens the pressure relief chamber, the inlet of the water inlet valve, the outlet of the water inlet valve, the inlet of the breather, the outlet of the breather, the housing inlet, the pressure relief chamber, the transition chamber, the housing outlet, and the cup inlet are sequentially connected. By incorporating a pressure relief chamber and placing a pressure relief valve within it in the housing assembly, the valve opens promptly when the filter element becomes clogged with impurities from tap water, reducing its flow capacity. At this point, the inlet of the scale-inhibiting filter connects directly to the pressure relief chamber and discharges from its outlet, effectively preventing damage from excessive tap water pressure and extending the device's lifespan. Furthermore, the timely opening of the pressure relief valve when water flow decreases due to filter element blockage creates a unique emergency water flow channel. This channel connects the inlet and outlet of the inlet valve, the breather inlet and outlet, the housing inlet, the pressure relief chamber, the receiving chamber, the housing outlet, and the cup inlet. This emergency path cleverly avoids the obstructed filter element, preventing damage under excessive pressure and effectively extending its lifespan. Meanwhile, the water flow, passing through the pressure relief chamber, quickly bypasses the blockage point, ensuring the basic smooth flow of water throughout the system and maintaining normal water supply for users. This avoids the embarrassing situation of having no water available due to filter blockage. Furthermore, the breather continuously functions to balance system pressure and ensure stable water flow. This design greatly enhances the system's stability and reliability in unexpected situations such as filter blockage, providing users with an uninterrupted and relatively stable water experience, comprehensively protecting users' water safety and convenience.

[0014] In one embodiment, the housing assembly includes a main housing and a top cover. The top cover is disposed on the main housing, and the top cover and the main housing enclose the receiving cavity. The main housing has a housing outlet. The water inlet valve outlet is connected to the breather inlet, the breather outlet to the housing inlet, and the housing outlet to the cup inlet via pipes. By connecting the water inlet valve outlet to the breather inlet, the breather outlet to the housing inlet, and the housing outlet to the cup inlet via pipes, stable water flow within the system is ensured, effectively preventing water leakage or turbulence and guaranteeing the efficient operation of the entire system. Whether in normal operation or when the pressure relief valve is opened after filter blockage, the water flow can smoothly pass through each component along a predetermined path. Furthermore, the pipe connection method makes the installation, disassembly, and maintenance of each part of the system more convenient. When a component malfunctions or needs to be replaced, the corresponding pipe can be easily operated, greatly saving maintenance time and labor costs, comprehensively improving the reliability and practicality of the system, and bringing users a better water experience.

[0015] In one embodiment, the housing assembly includes a main housing and a top cover. The top cover is disposed on the main housing, and the top cover and the main housing enclose the receiving cavity. The top cover has multiple housing water outlets. The water outlet of the inlet valve is connected to the water inlet of the respirator, and the water outlet of the respirator is connected to the water inlet of the housing via pipes. These multiple housing water outlets are connected to the cup body. By providing multiple housing water outlets on the top cover and directly connecting them to the cup body, combined with the pipe connections between the water outlet of the inlet valve and the water inlet of the respirator, and between the water outlet of the respirator and the water inlet of the housing, certain advantages are offered. Multiple housing water outlets enable efficient water flow distribution, meeting the user's water needs in various scenarios and greatly improving water usage convenience. After the water flows through the system and completes filtration and scale inhibition, it can quickly flow from different outlets to the cup body, making it easier for the user to obtain water. At the same time, this design simplifies traditional complex pipe connections and reduces costs.

[0016] A third aspect of this application discloses a dishwasher, which includes: the aforementioned filter and scale-inhibiting water system; and a dishwasher body, wherein the filter and scale-inhibiting water system is disposed on the dishwasher body.

[0017] The third aspect of this application discloses a dishwasher in which a filtration and scale-inhibiting water system is integrated into the dishwasher body. This system effectively intercepts impurities in the water, prevents scale formation, and ensures that the water entering the dishwasher is clean and free of contaminants. This significantly improves the dishwasher's operational stability, preventing impurities in the water from clogging pipes or scale from adhering to critical components such as heating elements and spray arms, thus extending the dishwasher's lifespan. Simultaneously, clean water significantly improves the cleaning effect on tableware, reducing stain residue and leaving tableware looking brand new. Furthermore, the simplified structure and convenient maintenance design of the filtration and scale-inhibiting water system also reduce the difficulty and cost of dishwasher maintenance.

[0034] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0036] The following describes, with reference to the accompanying drawings, some embodiments of the dishwasher, including a scale-inhibiting filter device, a scale-inhibiting water system, and a dishwasher.

[0037] Example 1

[0038] like Figures 1 to 7 As shown, this embodiment discloses a filter scale inhibition device for a dishwasher, including: a housing assembly 1, the housing assembly 1 having a receiving cavity 101, the housing assembly 1 having a housing inlet 103 and a housing outlet 104 communicating with the receiving cavity 101; a filter element 2, the filter element 2 being disposed on the housing assembly 1 and located within the receiving cavity 101, the filter element 2 having a processing cavity 201, and a transition cavity being formed between the filter element 2 and the cavity wall of the receiving cavity 101; and a scale inhibition assembly 3, at least a portion of the scale inhibition assembly 3 being located within the processing cavity 201, the housing inlet 103, the processing cavity 201, the transition cavity, and the housing outlet 104 being sequentially connected.

[0039] This application discloses a scale-inhibiting filter for a dishwasher, which boasts significant advantages in its innovative structural design compared to traditional scale-inhibiting devices. Both the filter element 2 and the scale-inhibiting component 3 are cleverly housed within the receiving cavity 101 of the housing component 1, a layout that significantly reduces the device's size. Traditional scale-inhibiting filters often contain multiple independent cavities such as a brine chamber and a resin chamber, resulting in a large overall size and occupying considerable space. This device, however, requires only a single scale-inhibiting receiving cavity 101, greatly saving installation space and making it easier to use in various space-constrained environments. Simultaneously, this device effectively expands its functionality. It not only has scale-inhibiting capabilities but also adds the function of filtering impurities from tap water. By intercepting impurities in the water through the filter element 2, water quality is effectively purified, reducing the damage of impurities to subsequent water-using equipment. Furthermore, by omitting the brine chamber and resin chamber, the device's structure becomes simpler, and the number of parts is significantly reduced. This not only reduces manufacturing costs but also makes assembly, maintenance, and repair of the device more convenient. Fewer parts mean a lower failure rate, improving the device's stability and reliability. In addition, the pressure relief valve 4 provides reliable safety assurance for the device. The scale inhibition component 3 is placed inside the treatment chamber 201, allowing it to fully contact the flowing water. When water enters the treatment chamber 201 from the inlet 103 of the housing, the scale inhibition component 3 effectively intercepts and adsorbs calcium, magnesium, and other ions in the water, preventing scale formation. Simultaneously, in conjunction with the filter element 2 within the treatment chamber, it filters impurities such as sediment and rust from the water, achieving a dual function of impurity interception and scale inhibition, improving water purification efficiency, and ensuring the normal operation of subsequent water-using equipment.

[0040] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further defines: the housing assembly 1 includes a main housing 11 and a top cover 12, the top cover 12 is disposed on the main housing 11, and the top cover 12 and the main housing 11 enclose a receiving cavity 101. One end of the filter element 2 is disposed on the housing assembly 1, and a portion of the scale inhibitor assembly 3 is sandwiched between the top cover 12 and the other end of the filter element 2. By utilizing the top cover 12 and the main housing 11 to enclose the receiving cavity 101, the filter element 2 and the scale inhibitor assembly 3 are orderly integrated therein, making the entire device structure compact. Compared with a distributed layout, this design significantly reduces the space occupied by the device, saving installation space and facilitating integration into various water-using equipment or systems, thus improving space utilization efficiency. One end of the filter element 2 is firmly disposed on the housing assembly 1, and a portion of the scale inhibitor assembly 3 is sandwiched between the top cover 12 and the filter element 2, ensuring that both are fixed in position under the impact of water flow and will not shift or shake. This allows water to flow steadily through the filter element and scale inhibitor components, fully utilizing the filter element's impurity filtration and the scale inhibitor components' scale prevention functions to ensure the stability and continuity of water purification effects.

[0041] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the housing assembly 1 also includes an annular housing 13, which extends toward the top cover 12 and is disposed at one end of the housing assembly 1 in close contact with the filter element 2; the top cover 12 is detachable from the main housing 11. By utilizing the close contact between the annular housing 13 and the filter element 2, the filter element is provided with certain support and fixation, effectively preventing displacement or shaking of the filter element under the impact of water flow, ensuring stable operation of the filter element. In addition, the annular housing 13, the main housing 11, and the top cover 12 together form a stable device frame, enhancing the strength and stability of the overall structure and improving the durability of the device. At the same time, the arrangement of the annular housing 13 extending toward the top cover 12 and being disposed at one end of the housing assembly 1 in close contact with the filter element 2 strengthens the filtration process. Before entering the filter element 2, the water flow undergoes preliminary buffering and distribution within the annular space, allowing the water flow to pass through the filter element 2 more evenly, greatly improving the filtration efficiency and making impurities intercepted more thoroughly. Moreover, the annular housing does not increase the difficulty of disassembly during later maintenance. When the top cover 12 is opened to replace the filter element, the annular housing not only does not obstruct the process, but also makes it easier to place the filter element 2 back into the anti-scaling device after replacement. This maintains the device's advantage of simple maintenance, providing users with an efficient and worry-free experience. By detachably attaching the top cover 12 to the main housing 11, when the filter element 2 of the anti-scaling device becomes clogged, its filtration efficiency decreases, or the anti-scaling component 32 in the anti-scaling assembly 3 fails, the top cover 12 can be removed to directly access the internal filter element 2 and anti-scaling assembly 3, allowing for quick replacement. This eliminates the need for complex disassembly of the entire device, reducing maintenance difficulty and time costs, and ensuring continuous and efficient operation.

[0042] like Figure 1 , Figure 2 and Figure 4As shown, in addition to the features of the above embodiments, this embodiment further defines: the scale inhibition assembly 3 includes a housing 31 and scale inhibition components 32. A portion of the housing 31 is sandwiched between the housing assembly 1 and the filter element 2. The housing 31 extends into the treatment chamber 201 and has a placement cavity 301. The scale inhibition components 32 are disposed on the housing 31 and located within the placement cavity 301. By cleverly sandwiching the housing 31 between the housing assembly 1 and the filter element 2, and providing the placement cavity 301 internally, multiple scale inhibition components 32 are arranged in an orderly manner. The numerous scale inhibition components 32 work together, greatly expanding the contact area with the water flow, fully utilizing the scale inhibition effect, and efficiently intervening in ions in the water that easily form scale. Compared to a single scale inhibition component, this significantly improves the scale inhibition capacity, effectively reducing scale deposition in pipes and water-using equipment, and extending the service life of the equipment. The housing 31 makes the installation of the entire scale inhibition assembly 3 more stable and convenient. During later maintenance, if it is necessary to inspect or replace the scale inhibitor 32, simply open the top cover 12, remove the housing 31, and operate on the internal scale inhibitor 32. This eliminates the need for large-scale disassembly of the entire device, significantly saving maintenance time and labor costs. Furthermore, the configuration of multiple scale inhibitors 32 ensures that even after some are worn out, others maintain a certain level of scale inhibition performance, guaranteeing continuous and stable operation of the device throughout the maintenance cycle. This provides users with a more reliable and efficient scale inhibition experience, comprehensively improving water quality.

[0043] like Figure 1 , Figure 2 and Figure 4As shown, in addition to the features of the above embodiments, this embodiment further defines: the housing 31 includes a top housing 311 and a main housing 312. The top housing 311 is sandwiched between the housing assembly 1 and the filter element 2. The main housing 312 is disposed on the top housing 311 and located in the treatment chamber 201. The main housing 312 extends along the length of the treatment chamber 201. Scale inhibitors 32 are disposed on the main housing 312, and the main housing 312 has a housing cavity 301. By precisely sandwiching the top housing 311 between the housing assembly 1 and the filter element 2, this arrangement ensures that the entire scale inhibitor assembly is installed stably, avoiding displacement under water flow impact and affecting the scale inhibition effect. The main housing 312 is disposed on the top housing 311 and extends along the length of the treatment chamber 201, cleverly utilizing the internal space. Multiple scale inhibitors 32 are evenly distributed on the main housing 312, and the main housing 312 has a housing cavity 301. This structural design ensures that the water flow, as it passes through the treatment chamber 201, fully contacts each scale inhibitor 32. The extended layout of the main housing 312 expands the effective range of the water flow and the scale inhibitor 32, greatly improving scale inhibition efficiency, effectively reducing the possibility of scale formation in the water, and providing comprehensive protection for pipes and water-using equipment from scale buildup, thus extending their service life. When it is necessary to inspect or replace the scale inhibitor 32, simply open the top cover 12 to easily remove the top housing 311 and its connected main housing 312, eliminating the need for complex operations and significantly saving maintenance time and labor costs. Even when some scale inhibitor 32 is damaged, the others can still function normally, maintaining the scale inhibition performance of the device and ensuring the stability of water quality.

[0044] like Figure 1 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: it also includes an inner tank bottom plate 5, and the shell assembly 1 also includes a fixing member 14 and a sealing member 15. The fixing member 14 and the sealing member 15 are disposed on the main shell 11, and a portion of the inner tank bottom plate 5 is sandwiched between the fixing member 14 and the sealing member 15. By disposing the fixing member 14 and the sealing member 15 on the main shell 11, stable support is provided for the inner tank bottom plate 5. The fixing member 14 ensures that the inner tank bottom plate 5 is firmly installed and will not shift even under continuous water flow impact, ensuring the stability of the internal structure of the device. The sealing member 15 plays a good sealing role, effectively preventing water leakage, maintaining the normal operation of the device, and avoiding damage to the surrounding environment or device malfunction due to water leakage. The inner tank bottom plate 5 is installed between the sealing members 15, which not only participates in building a stable internal structure, but also can work together with the fixing member and the sealing member during maintenance, facilitating overall disassembly and inspection, greatly improving maintenance efficiency, and comprehensively ensuring the reliability and durability of the device.

[0045] Example 2

[0046] like Figures 1 to 7As shown, this embodiment discloses a scale-inhibiting water circuit system, including: the scale-inhibiting device of the dishwasher mentioned above; a water inlet valve 6, which has a water inlet 601 and a water outlet 602; a breather 7, which has a breather inlet 701 and a breather outlet 702; and a cup body 8, which has a cup body inlet 801. The water inlet valve 6, the breather 7, the scale-inhibiting device of the dishwasher, and the cup body 8 are arranged in sequence.

[0047] The second aspect of this application discloses a water filtration and scale inhibition system. The filter and scale inhibition device, with its unique structure, effectively filters impurities and prevents scale formation. The inlet valve 6 precisely controls the water flow, ensuring a stable water supply; its rational inlet and outlet design makes water distribution more scientific. The breather 7 balances the pressure inside and outside the system, preventing negative pressure and ensuring smooth water flow, avoiding air backflow and water quality contamination. The cup 8 is used to collect the purified water, providing users with a convenient way to obtain water. The entire system operates collaboratively, comprehensively ensuring the safety, cleanliness, and convenience of water use, greatly enhancing the user's water experience.

[0048] like Figure 1 , Figure 2 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the housing assembly 1 is provided with a pressure relief chamber 102, the housing inlet 103, the pressure relief chamber 102, the transition chamber and the housing outlet 104 are sequentially connected, and it also includes a pressure relief valve 4, which is disposed on the housing assembly 1 and located in the pressure relief chamber 102. The pressure relief valve 4 can open or block the pressure relief chamber 102; when the pressure relief valve 4 blocks the pressure relief chamber 102, the water inlet 601 and the water outlet 602 of the water inlet valve are closed. The breathing apparatus inlet 701, breathing apparatus outlet 702, housing inlet 103, treatment chamber 201, transition chamber, housing outlet 104, and cup inlet 801 are sequentially connected. When the pressure relief valve 4 opens the pressure relief chamber 102, the inlet valve inlet 601, inlet valve outlet 602, breathing apparatus inlet 701, breathing apparatus outlet 702, housing inlet 103, pressure relief chamber 102, transition chamber, housing outlet 104, and cup inlet 801 are sequentially connected. By setting the pressure relief chamber 102 in the housing assembly 1 and placing the pressure relief valve 4 in the pressure relief chamber 102, when the filter element 2 is blocked by impurities in the tap water and the water flow capacity is reduced, the pressure relief valve 4 will open in time. At this time, the inlet of the filter scale inhibitor will directly connect to the pressure relief chamber 102 and be discharged from the outlet of the filter scale inhibitor, effectively preventing the filter scale inhibitor from being damaged by excessive tap water pressure and extending the service life of the device. By utilizing the pressure relief valve 4, when the water flow decreases due to filter element 2 clogging by impurities, the timely opening of the pressure relief valve 4 causes the inlet 601, outlet 602, breather inlet 701, outlet 702, housing inlet 103, pressure relief chamber 102, receiving chamber 101, housing outlet 104, and cup inlet 801 to connect sequentially, forming a special emergency water flow channel. This emergency channel cleverly avoids the obstructed filter element 2, preventing damage to the filter element under excessive pressure and effectively extending its service life. Simultaneously, the water flow through the pressure relief chamber 102 quickly bypasses the blockage point, ensuring the basic unobstructed water flow of the entire system, maintaining normal water supply for users, and avoiding the embarrassing situation of no water due to filter element clogging. Furthermore, the breather continues to function, balancing system pressure and ensuring stable water flow. This design greatly enhances the stability and reliability of the system in the event of sudden events such as filter blockage, providing users with an uninterrupted and relatively stable water use experience and comprehensively protecting users' water safety and convenience.

[0049] like Figure 2 , Figure 3 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the housing assembly 1 includes a main housing 11 and a top cover 12. The top cover 12 is disposed on the main housing 11, and the top cover 12 and the main housing 11 enclose a receiving cavity 101. The main housing 11 is provided with a housing outlet 104. The water inlet valve outlet 602 is connected to the breather inlet 701, the breather outlet 702 is connected to the housing inlet 103, and the housing outlet 104 is connected to the cup inlet 801 through pipes. By using pipes to connect the water inlet valve outlet 602 to the breather inlet 701, the breather outlet 702 to the housing inlet 103, and the housing outlet 104 to the cup inlet 801, the stable transmission of water flow within the system is ensured, effectively preventing water leakage or turbulence, and ensuring the efficient operation of the entire system. Whether in normal working condition or when the pressure relief valve is opened after the filter element is clogged, the water flow can smoothly pass through each component according to the predetermined path. Meanwhile, the pipe connection method makes the installation, disassembly, and maintenance of each part of the system more convenient. When a component fails or needs to be replaced, the corresponding pipe can be easily operated, greatly saving maintenance time and labor costs, comprehensively improving the reliability and practicality of the system, and bringing users a better water experience.

[0050] like Figure 2 , Figure 3 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the housing assembly 1 includes a main housing 11 and a top cover 12. The top cover 12 is disposed on the main housing 11, and the top cover 12 and the main housing 11 enclose a receiving cavity 101. The top cover 12 is provided with housing water outlets 104, and there are multiple housing water outlets 104. The water inlet valve outlet 602 is connected to the respirator water inlet 701, and the respirator water outlet 702 is connected to the housing water inlet 103 through pipes. The multiple housing water outlets 104 are connected to the cup body 8. By providing multiple housing water outlets 104 on the top cover 12 and directly connecting them to the cup body 8, and combining the pipe connections between the water inlet valve outlet 602 and the respirator water inlet 701, and the respirator water outlet 702 and the housing water inlet 103, certain advantages are provided. The multiple housing water outlets 104 can achieve efficient water flow distribution, meet the water needs of users in multiple scenarios, and greatly improve the convenience of water use. After the water flows through the system and undergoes filtration and scale inhibition, it can quickly flow from different outlets to the cup, making it easier for users to get water. At the same time, this design simplifies the traditional complex piping connections, resulting in lower costs.
