Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a dishwasher. Background Technology

[0002] In the kitchen appliance sector, dishwashers, as products that greatly enhance the convenience of daily life, have always seen a focus on optimizing their functionality and performance. Among them, dishwashers with water softening functions are widely welcomed by the market because they can effectively reduce the damage of limescale to the internal components of the dishwasher and to the tableware.

[0003] Most dishwashers with water softening functions on the market have a salt inlet designed to extend inside the dishwasher, allowing users to easily add salt. However, existing salt inlet caps have a significant drawback. These caps typically use a threaded design, which, while providing a degree of seal, requires manual tightening. In practice, due to user habits and oversight, users often fail to tighten the cap after adding salt.

[0004] If the water softener cap is not tightened properly, it can cause a series of serious problems. The brine stored inside the water softener can leak into the dishwasher's washing chamber, potentially damaging the dishwasher's internal structure, affecting its normal performance, and even shortening its lifespan. This not only results in financial losses for the user but also impacts their user experience and satisfaction. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, the purpose of this utility model is to provide a dishwasher that uses a fixing ring to fix the salt inlet section of the water softener inside the dishwasher, and uses a magnetic sealing connection between the salt cap and the fixing ring. The operation is simple, does not require the user to tighten it, and avoids salt water leakage into the washing chamber of the dishwasher, which may cause rust and damage.

[0006] This utility model provides a dishwasher, comprising: Dishwasher body and retaining ring; A water softener includes a housing, the housing having a brine chamber inside, and a pipe section communicating with the brine chamber on the housing; the pipe section passes through the dishwasher body and connects to the inner ring side of the fixing ring to fix the water softener to the dishwasher body; A salt-adding cap is attached to the pipe opening section and abuts against the upper end face of the fixing ring; a magnetic sealing structure is provided between the salt-adding cap and the fixing ring to achieve a magnetic sealing connection.

[0007] In the above technical solution, the dishwasher incorporates a magnetic sealing structure between the salt cap and the retaining ring, greatly enhancing user convenience. When adding salt, users simply remove and replace the salt cap; the magnetic force ensures a tight connection between the cap and the retaining ring, eliminating the need for laborious thread tightening as in the past. This effectively prevents leakage of brine from the water softener's salt chamber into the dishwasher's washing chamber due to loose threads, preventing rusting of the washing chamber and extending the overall lifespan of the dishwasher. Simultaneously, the retaining ring provides a secure hold for the water softener, working in conjunction with the magnetic sealing structure to ensure the long-term stability and reliability of the water softener and related connections.

[0008] In some embodiments, the magnetic sealing structure includes a first magnetic sealing assembly and a second magnetic sealing assembly, and the salt cap has a cavity that is fastened to the outer periphery of the pipe opening section; The first magnetic sealing assembly is located on the lower end face of the salt cap on the outer periphery of the opening of the cavity, and the second magnetic sealing assembly is located on the upper end face of the fixing ring and abuts against the first magnetic sealing assembly.

[0009] In the above technical solution, by setting a magnetic sealing structure including a first magnetic sealing component and a second magnetic sealing component, and by having a cavity that snaps onto the outer periphery of the pipe opening section, the first magnetic sealing component is located on the lower end face of the outer periphery of the cavity opening of the salt cap, and the second magnetic sealing component is located on the upper end face of the fixing ring and abuts against the first magnetic sealing component, the problem of tight connection is effectively solved. During the installation of the salt cap, the snapping of the cavity onto the pipe opening section and the mutual attraction between the first and second magnetic sealing components create a multi-layered tight connection between the salt cap and the fixing ring, greatly enhancing the stability of the connection.

[0010] In some embodiments, the first magnetic sealing assembly includes a first sealing ring and a first magnetic body, and the second magnetic sealing assembly includes a second sealing ring and a second magnetic body; the first sealing ring abuts against the second sealing ring, and the first magnetic body and the second magnetic body are vertically aligned and mutually attracted.

[0011] In the above technical solution, the first magnetic body and the second magnetic body can be in contact or spaced apart, as long as their vertical positions are opposite and they can attract each other. The setting method is more flexible, and with the abutment of the first sealing ring and the second sealing ring, the magnetic sealing structure achieves double sealing reinforcement.

[0012] In some embodiments, the lower end face of the salt cap is provided with a first annular groove, and the upper end face of the fixing ring is provided with a second annular groove; The first sealing ring is located at the opening of the first annular groove, and the second sealing ring is located at the opening of the second annular groove, and abuts against the first sealing ring for sealing.

[0013] In the above technical solution, the combination of the sealing ring and the annular groove effectively solves the problems of sealing ring displacement and uneven compression that are prone to occur in traditional planar sealing structures, and significantly improves the durability and reliability of the seal.

[0014] In some embodiments, the first magnetic body is disposed in the first annular groove, and the second magnetic body is disposed in the second annular groove.

[0015] In the above technical solution, the magnetic body and the sealing ring are placed together in the annular groove, and the sealing ring blocks the opening of the annular groove, so that the magnetic attraction force is evenly applied to the entire sealing ring. Under the drive of the magnetic attraction force, the sealing ring achieves axial uniform compression and radial expansion, thus realizing a high tight connection between the salt cap and the fixing ring.

[0016] In some embodiments, the first sealing ring wraps around the first magnetic body and is integrally embedded in the first annular groove, and the second sealing ring wraps around the second magnetic body and is integrally embedded in the second annular groove; The first magnetic body and the second magnetic body attract each other, causing the first sealing ring and the second sealing ring to come into contact and seal.

[0017] In the above technical solution, by wrapping the magnetic body with a sealing ring and integrally embedding it within the annular groove, the magnetic force is uniformly and stably transmitted to the sealing ring, significantly enhancing the magnetic strength and sealing performance. The sealing ring completely encapsulates the magnetic body and is integrally embedded with the annular groove, effectively preventing displacement during use and significantly improving the connection tightness, thereby enhancing the overall reliability and lifespan of the dishwasher.

[0018] In some embodiments, the first magnetic body is an annular magnet, and the first sealing ring covers the outside of the annular magnet and partially protrudes from the first annular groove.

[0019] In some embodiments, the second magnetic body is a plurality of arc-shaped magnets spaced apart circumferentially, and the second sealing ring covers the outside of the plurality of arc-shaped magnets and partially protrudes from the first annular groove.

[0020] In the above technical solution, the strong mutual attraction between the first and second magnetic bodies improves the tightness of the connection. The protruding portions of the first and second sealing rings form an effective sealing contact, avoiding leakage problems caused by uneven magnetic force distribution or sealing ring displacement. Furthermore, the encapsulation structure protects the magnetic bodies from corrosion and wear, extending the service life of the magnetic sealing structure.

[0021] In some embodiments, a reed switch is also included, disposed within the second annular groove, to close and send a salt cap closing signal upon being subjected to the magnetic force of the first magnetic body.

[0022] In the above technical solution, by setting a reed switch in the second annular groove, the automatic detection and signal feedback of the salt cap's closed state are realized. The dishwasher control system reminds the user whether the salt cap is closed, and the closed signal feedback enhances the system's reliability. This dual protection avoids the risk of leakage caused by the salt cap not being fully closed.

[0023] In some embodiments, the number of reed switches is multiple, and the multiple reed switches are alternately arranged with multiple arc-shaped magnets along the circumferential direction, and the second sealing ring covers the outside of the multiple reed switches and the multiple arc-shaped magnets.

[0024] In the above technical solution, the second sealing ring covers multiple reed switches and the second magnetic body, which can not only maintain the stable connection between the sealing ring and the second magnetic body, but also protect the reed switches from corrosion of their internal components, ensuring long-term stable operation and guaranteeing the structural stability of the second magnetic sealing assembly.

[0030] To better understand the above-mentioned objectives, features, and advantages of this utility model, the solution of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] An embodiment of this utility model provides a dishwasher, which includes an inner tank, a spray system, a water circulation system, and a control system. The dishwasher can be a sink-type or a built-in dishwasher.

[0034] This embodiment uses a built-in dishwasher as an example. The outer shell provides protection and support, while the inner liner provides space for tableware. During operation, the water circulation system delivers water to the spray system. The spray arms rotate under power, spraying high-pressure water from multiple angles to thoroughly rinse away stains on the tableware surface. Simultaneously, the heating element heats the water, enhancing the cleaning effect. The control system precisely regulates parameters such as water temperature, water flow intensity, and washing time. Through the coordinated operation of these structures, efficient and convenient tableware cleaning is achieved, meeting the diverse cleaning needs of tableware in different scenarios.

[0035] like Figures 1 to 10 As shown, the dishwasher includes a dishwasher body 1 and a water softener 2.

[0036] The dishwasher body 1 includes core components such as the casing, washing chamber, motor, and spray arms to perform basic dishwashing functions. The casing is generally rectangular in shape, and its interior is divided into different spaces according to functional requirements, such as the washing chamber and the motor mounting chamber. The water softener 2 is used to soften the water entering the dishwasher. The water softener 2 includes a housing 21. The housing 21 contains a brine chamber and a resin chamber. The brine chamber stores a high-concentration brine (usually a sodium chloride solution) as a raw material for resin regeneration. The resin chamber is filled with a resin layer to soften the water entering the dishwasher. During water softening, calcium and magnesium ions are adsorbed by the resin as water passes through the resin layer, while sodium ions are released into the water, generating soft water. Once the resin becomes saturated, its softening capacity decreases, requiring regeneration to restore it. Brine is drawn from the brine chamber into the resin chamber, where sodium ions replace the calcium and magnesium ions on the resin, restoring resin activity through a replacement reaction. The displaced calcium and magnesium ions are discharged with the wastewater.

[0037] The dishwasher also includes a retaining ring 23 for securing the water softener 2 to the dishwasher body 1. The water softener 2 includes a housing 21 and a salt filling cap 22. The housing 21 has a pipe section communicating with the salt chamber for adding salt into the salt chamber. The pipe section extends into the dishwasher body 1, and the opening of the pipe section communicates with the interior of the dishwasher body 1. The portion of the pipe section located inside the dishwasher body 1 is connected to the inner ring side of the retaining ring 23 to secure the water softener 2 to the dishwasher body 1.

[0038] The salt cap 22 is fastened to the pipe opening to seal it and prevent leakage of substances from the salt chamber. The salt cap 22 abuts against the upper end face of the fixing ring 23. A magnetic sealing structure 3 is provided between the salt cap 22 and the fixing ring 23, which uses magnetic attraction to tightly connect the two and also serves as a seal.

[0039] In this embodiment, the dishwasher incorporates a magnetic sealing structure 3 between the salt cap 22 and the retaining ring 23, greatly enhancing user convenience. When adding salt, the user simply removes and replaces the salt cap 22, achieving a tight connection between the cap and the retaining ring 23 through magnetic attraction. This eliminates the need for laborious thread tightening, effectively preventing leakage of brine from the water softener 2's salt chamber into the dishwasher's washing chamber due to loose threads, thus preventing rusting of the washing chamber and extending the overall lifespan of the dishwasher. Simultaneously, the retaining ring 23 provides a stable fixation for the water softener 2, working in conjunction with the magnetic sealing structure 3 to ensure the long-term stability and reliability of the water softener 2 and its related connecting structures.

[0040] It should be noted that the inner diameter of the retaining ring 23 is matched with the outer diameter of the water softener 2 pipe section to ensure a tight connection. The inner ring side of the retaining ring 23 can be snap-fitted or threaded onto the water softener 2 pipe section. Preferably, the magnetic sealing structure 3 includes a magnetic part and a sealing part. The sealing part has good elasticity and sealing performance, while the magnetic part has strong magnetism, providing sufficient attraction to tightly connect the salt cap 22 and the retaining ring 23. The seal is achieved through the sealing part between the salt cap 22 and the retaining ring 23.

[0041] When salt needs to be added to the brine chamber of the water softener 2, the user simply needs to overcome the magnetic attraction of the magnetic sealing structure 3 and remove the salt cap 22 from the pipe opening. Then, add an appropriate amount of salt into the brine chamber through the pipe opening. After adding the salt, reattach the salt cap 22 to the pipe opening, ensuring that the lower end face of the salt cap 22 is tightly against the upper end face of the retaining ring 23. At this time, the magnetic sealing structure 3 between the salt cap 22 and the retaining ring 23 comes into play, with the magnetic parts attracting each other, causing the salt cap 22 to fit tightly against the retaining ring 23. At the same time, the sealing part effectively prevents the brine in the brine chamber from leaking into the dishwasher's washing chamber through the gap between the pipe opening and the salt cap 22.

[0042] like Figure 3 As shown, the magnetic sealing structure 3 includes a first magnetic sealing assembly 31 and a second magnetic sealing assembly 32. The salt cap 22 has a cavity 221. The cavity 221 is fastened to the outer periphery of the pipe opening section. The first magnetic sealing assembly 31 is located on the lower end face of the salt cap 22 located on the outer periphery of the opening of the cavity 221. The second magnetic sealing assembly 32 is located on the upper end face of the fixing ring 23 and abuts against the first magnetic sealing assembly 31.

[0043] In this embodiment, by setting a magnetic sealing structure 3 including a first magnetic sealing component 31 and a second magnetic sealing component 32, and the salt cap 22 having a cavity 221 that is fastened to the outer periphery of the pipe opening section, the first magnetic sealing component 31 is located on the lower end face of the outer periphery of the opening of the cavity 221 of the salt cap 22, and the second magnetic sealing component 32 is located on the upper end face of the fixing ring 23 and abuts against the first magnetic sealing component 31, the problem of tight connection is effectively solved. When installing the salt cap 22, the fastening of the cavity 221 to the pipe opening section and the mutual attraction of the first and second magnetic sealing components 32 form a multi-layered tight connection between the salt cap 22 and the fixing ring 23, greatly enhancing the stability of the connection.

[0044] Preferably, the salt cap 22 is circular in shape, and the recess 221 on it is cylindrical, with the inner diameter of the recess 221 matching the outer diameter of the pipe opening. The lower end face of the salt cap 22 located on the outer periphery of the opening of the recess 221 is a flat annular surface. The fixing ring 23 is an annular structure with a flat annular surface on its upper end face, corresponding to the lower end face of the salt cap 22.

[0045] When it is necessary to install the salt cap 22 onto the water softener 2 pipe opening, align the recess 221 of the salt cap 22 with the pipe opening and snap it down, so that the lower end face of the salt cap 22 located on the outer periphery of the recess 221 gradually approaches and abuts against the upper end face of the fixing ring 23.

[0046] like Figures 4 to 10 As shown, the first magnetic sealing assembly 31 includes a first sealing ring 311 and a first magnetic body 312, and the second magnetic sealing assembly 32 includes a second sealing ring 321 and a second magnetic body 322; the first sealing ring 311 and the second sealing ring 321 abut against each other, and the first magnetic body 312 and the second magnetic body 322 are vertically opposite to each other and mutually attracted.

[0047] In this embodiment, the first magnetic body 312 and the second magnetic body 322 can be in contact or spaced apart, as long as their vertical positions are opposite and they can attract each other. The setting method is more flexible. In addition, with the abutment of the first sealing ring 311 and the second sealing ring 321, the double sealing reinforcement of the magnetic sealing structure 3 is achieved.

[0048] The first magnetic body 312 is spaced apart from the first sealing ring 311 and is located on the inner ring side or outer ring side of the first sealing ring 311. Alternatively, the first magnetic body 312 is attached to or embedded in one side (inner ring side, outer ring side, or top side) of the first sealing ring 311.

[0049] Since the first sealing ring 311 abuts against the second sealing ring 321, the first magnetic body 312 and the second magnetic body 322 are vertically opposite each other. Therefore, based on the same principle, the second magnetic body 322 is spaced apart from the second sealing ring 321 and is located on the inner ring side or outer ring side of the second sealing ring 321. Alternatively, the second magnetic body 322 is fitted to or embedded in the side of the second sealing ring 321 away from the first sealing ring 311 (the inner ring side, outer ring side, or top side of the second sealing ring 321).

[0050] The first magnetic body 312 and the second magnetic body 322 are arranged in vertical contact with each other, or the first magnetic body 312 and the second magnetic body 322 are spaced apart and arranged vertically opposite each other. At least one of the first magnetic body 312 and the second magnetic body 322 is annular. The first sealing ring 311 and the second sealing ring 321 can be bellows-type sealing rings or planar sealing rings.

[0051] like Figure 4 , Figure 6 , Figure 8 and Figure 10As shown, the lower end face of the salt-adding cap 22 is provided with a first annular groove 222, the opening of the first annular groove 222 facing the fixing ring 23. The upper end face of the fixing ring 23 is provided with a second annular groove 231, which is coaxially arranged with the first annular groove 222. The opening of the second annular groove 231 faces the salt-adding cap 22. A first sealing ring 311 is provided at the opening of the first annular groove 222. A second sealing ring 321 is provided at the opening of the second annular groove 231 and abuts against the first sealing ring 311 for sealing.

[0052] In this embodiment, by assembling the sealing ring with the annular groove, the problems of sealing ring displacement and uneven compression that are prone to occur in traditional planar sealing structures are effectively solved, and the durability and reliability of the seal are significantly improved.

[0053] It should be noted that the first magnetic body 312 can be disposed inside or outside the first annular groove 222. Similarly, the second magnetic body 322 can be disposed inside or outside the second annular groove 231.

[0054] Preferably, the first sealing ring 311 protrudes slightly from the opening of the first annular groove 222, and the second sealing ring 321 protrudes slightly from the opening of the second annular groove 231, forming an initial contact surface during engagement. For example, the first sealing ring 311 protrudes 0.5-1mm from the edge of the groove, and the second sealing ring 321 protrudes 0.5-1mm from the edge of the groove. The cross-section of the first annular groove 222 is semi-circular, rectangular, etc. The materials of the first sealing ring 311 and the second sealing ring 321 include, but are not limited to, silicone elastomers and rubber elastomers. The salt cap 22 can be made of materials including alloys (such as aluminum-magnesium alloys), stainless steel, plastics, and carbon fiber reinforced composite materials.

[0055] In some embodiments, the first magnetic body 312 is disposed in the first annular groove 222, and the second magnetic body 322 is disposed in the second annular groove 231.

[0056] The first magnetic body 312 and the second magnetic body 322 are strong magnets, such as neodymium iron boron (NdFeB) N52 grade strong magnets. The magnetic poles on opposite sides of the first magnetic body 312 and the second magnetic body 322 are opposite, forming a face-to-face mutual attraction.

[0057] In this embodiment, the magnetic body and the sealing ring are placed together in the annular groove, and the sealing ring blocks the opening of the annular groove, so that the magnetic attraction force is evenly applied to the entire sealing ring. Under the drive of the magnetic attraction force, the sealing ring achieves axial uniform compression and radial expansion, realizing a high tight connection between the salt cap 22 and the fixing ring 23.

[0058] The first magnetic body 312 can be disposed in the first annular groove 222 above the first sealing ring 311, or it can be disposed inside the first sealing ring 311. The second magnetic body 322 can be disposed in the second annular groove 231 below the second sealing ring 321, or it can be disposed inside the second sealing ring 321.

[0059] In some embodiments, a first sealing ring 311 encloses a first magnetic body 312 and is integrally embedded in a first annular groove 222. The first sealing ring 311 completely encloses and fixes the first magnetic body 312 in the first annular groove 222 through injection molding or vulcanization, forming a non-removable integral structure to ensure a gapless magnetic force transmission path. A second sealing ring 321 encloses a second magnetic body 322 and is integrally embedded in a second annular groove 231. Similarly, the second sealing ring 321 can completely enclose and fix the second magnetic body 322 in the second annular groove 231 through injection molding or vulcanization, forming a non-removable integral structure to ensure a gapless magnetic force application path. The first magnetic body 312 and the second magnetic body 322 attract each other, causing the first sealing ring 311 and the second sealing ring 321 to abut and seal.

[0060] In this embodiment, by encasing the magnetic body in a sealing ring and embedding it integrally within the annular groove, the magnetic force is uniformly and stably transmitted to the sealing ring, significantly enhancing the magnetic strength and sealing performance. The sealing ring completely encapsulates the magnetic body and is integrally embedded in the annular groove, effectively preventing displacement during use and significantly improving the connection tightness, thereby enhancing the overall reliability and lifespan of the dishwasher.

[0061] In one embodiment, both the first magnetic body 312 and the second magnetic body 322 are annular magnets (not shown in the figure). The first sealing ring 311 covers the outside of the first magnetic body 312 and partially protrudes from the first annular groove 222. The second sealing ring 321 covers the outside of the second magnetic body 322 and partially protrudes from the second annular groove 231.

[0062] Another implementation scheme is, as Figure 6 and Figure 10 As shown, the first magnetic body 312 is an annular magnet, and the first sealing ring 311 covers the outside of the annular magnet and partially protrudes from the first annular groove 222. The second magnetic body 322 consists of a plurality of arc-shaped magnets spaced apart circumferentially, and the second sealing ring 321 covers the outside of the plurality of arc-shaped magnets and partially protrudes from the second annular groove 231.

[0063] In this embodiment, the strong mutual attraction between the first magnetic body 312 and the second magnetic body 322 improves the tightness of the connection. The protruding portions of the first sealing ring 311 and the second sealing ring 321 form an effective sealing contact, avoiding leakage problems caused by uneven magnetic force distribution or sealing ring displacement. Furthermore, the encapsulation structure protects the magnetic bodies from corrosion and wear, extending the service life of the magnetic sealing structure 3.

[0064] Furthermore, the dishwasher also includes a reed switch 4. The reed switch 4 is a sensor element that controls the on / off state of a circuit via a magnetic field. It consists of two soft magnetic metal reeds sealed within a glass tube filled with an inert gas (such as nitrogen). When an external magnetic field approaches, the reeds are magnetized and attracted; when the magnetic field is removed, the reeds return to their open state. It features fast response (0.5-2ms), corrosion resistance, and low power consumption. The reed switch 4 is located within the second annular groove 231, and closes upon receiving the magnetic force of the first magnetic body 312, sending a signal to close the salt cap 22. The reed switch 4 is a miniature cylinder that can be embedded within the second annular groove 231.

[0065] A Hall effect sensor can be used to replace the reed switch 4, which outputs a signal by detecting changes in magnetic field strength, thereby improving the ability to resist vibration interference.

[0066] In this embodiment, by setting a reed switch 4 in the second annular groove 231, the automatic detection and signal feedback of the closed state of the salt cap 22 is realized. The dishwasher control system reminds the user whether the salt cap 22 is closed. The closed signal feedback enhances the system reliability, and the double protection avoids the risk of leakage caused by the salt cap 22 not being fully closed.

[0067] The multiple reed switches 4 can be disposed on the inner ring side or the outer ring side of the second magnetic body 322, or the second magnetic body 322 can be multiple arc-shaped magnets arranged circumferentially, with the multiple reed switches 4 and the multiple arc-shaped magnets arranged alternately circumferentially.

[0068] Preferably, the first magnetic body 312 is annular, and multiple reed switches 4 are alternately arranged with multiple arc-shaped magnets along the circumference. The second sealing ring 321 covers the outside of the multiple reed switches 4 and the multiple arc-shaped magnets.

[0069] In this embodiment, the second sealing ring 321 covers multiple reed switches 4 and the second magnetic body 322, which can not only maintain the stable connection between the sealing ring and the second magnetic body 322, but also protect the reed switches 4 from corrosion of their internal components, ensuring long-term stable operation and guaranteeing the structural stability of the second magnetic sealing assembly 32.
