Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, and in particular to a dishwasher water distribution valve with antibacterial function and a dishwasher. Background Technology

[0002] Dishwasher interiors typically contain three types of sprayers: bottom spray, middle spray, and top spray. The bottom spray is located at the bottom of the dishwasher interior, the middle spray at the bottom of the upper shelf, and the top spray at the top of the interior. These three sprayers work individually or in combination to create different cleaning modes. Each cleaning mode corresponds to a different water path, and each mode requires a different amount of water. The water distribution valve allocates the water pumped by the dishwasher's washing pump to different water paths according to a preset ratio and direction, ensuring that each part receives sufficient water for cleaning, achieving a balance between water conservation and efficient cleaning.

[0003] To better achieve water conservation and emission reduction, dishwashers circulate a portion of their washing water through a filter before sending it to the diversion valve for reuse. However, when this water mixes with food residue, bacteria multiply rapidly, resulting in a high bacterial count in the recycled water. Consequently, after washing, a significant amount of bacteria remains on the surface of the dishes, potentially impacting health and reducing the dishwasher's cleaning effectiveness. Furthermore, the proliferation of bacteria within the diversion valve can produce corrosive substances, damaging the valve and other components of the dishwasher.

[0004] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

Detailed Implementation

[0026] This utility model provides a dishwasher water distribution valve with antibacterial function and a dishwasher. To make the purpose, technical solution and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0027] Please see Figures 1-3 This utility model provides a dishwasher water distribution valve with antibacterial function, including a water cup 1 with a water distribution chamber 11, a water inlet pipe 2 connected to the water inlet of the water distribution chamber 11, a water distribution valve cover 3 sealed and fixed at the water outlet of the water distribution chamber 11, a water distribution plate 4 disposed in the water distribution chamber 11 and used to control the flow of the flow distribution valve cover 31, and a water distribution drive mechanism 5 for driving the water distribution plate 4 to rotate; the water distribution valve cover 3 and the water distribution plate 4 are coaxially arranged, the water distribution plate 4 has a flow distribution hole 41 and an antibacterial module 6 is provided at the bottom of the water distribution plate 4, the antibacterial module 6 is used to inhibit the reproduction of bacteria in the water flowing through the water distribution chamber 11.

[0028] When the dishwasher is working, the water pumped by the washing pump enters the water cup 1 with the water distribution chamber 11 through the water inlet pipe 2. The water distribution drive mechanism 5 drives the water distribution plate 4 to rotate. The water distribution plate 4 has a diversion hole 41. During its rotation, the position change of the diversion hole 41 controls the direction and distribution ratio of the water flow, so as to realize the distribution of water flow to different water channels in different washing modes.

[0029] As water flows through the water distribution chamber 11, the antibacterial module 6, located at the bottom of the water distribution plate 4, activates when water comes into contact with it, inhibiting the growth of bacteria. This ensures that even recycled washing water has its bacterial content effectively controlled as it passes through the water distribution valve. The water distribution valve cover 3 is coaxially aligned with the water distribution plate 4. The rotation of the water distribution plate 4, in conjunction with the outlet of the water distribution chamber 11, ensures that the antibacterial treated water is distributed according to a preset water path. This achieves both a reasonable distribution of water flow to meet the needs of different cleaning modes and the inhibition of bacterial growth to ensure cleaning effectiveness and the safety of equipment components.

[0030] Compared with existing technologies, the dishwasher water distribution valve provided by this utility model cleverly utilizes the bottom space of the water distribution plate 4 to set up an antibacterial module 6, which can effectively inhibit the growth of bacteria in the water flowing through the water distribution chamber 11, reduce the bacterial content in the recycled water, thereby reducing bacterial residue on the surface of the dishes after washing, protecting people's health, and improving the cleaning effect of the dishwasher. It also avoids the generation of corrosive substances in the water distribution chamber 11, extending the service life of the water distribution valve and other components.

[0031] In one implementation, see Figure 1As shown, the bottom surface of the water divider 4 is provided with a limiting edge 71 that matches the shape of the antibacterial module 6. Two latches 72 on the limiting edge 71 secure the antibacterial module 6 to the bottom surface of the water divider 4. During dishwasher operation, the impact of water flow and the rotation of the water divider 4 may exert a certain force on the antibacterial module 6. The limiting edge 71 effectively restricts the displacement of the antibacterial module 6, preventing it from affecting the antibacterial effect or the normal operation of the water divider valve due to shaking or displacement. The two latches 72 firmly fix the antibacterial module 6 to the bottom surface of the water divider 4, ensuring that the antibacterial module 6 remains stably in the working position under various operating conditions and will not fall off due to machine vibration or water flow impact, thus ensuring the continuity and reliability of the antibacterial function. When the antibacterial module 6 needs to be replaced, the design of the latches 72 makes disassembly relatively simple, facilitating maintenance by users or repair personnel and reducing operational difficulty and time costs.

[0032] With the use of the dishwasher, dirt and other substances that affect the antibacterial performance may accumulate on the surface of the antibacterial module 6. Since the antibacterial module 6 is hidden inside the water distribution valve, disassembling the valve is not only cumbersome but may also require professional assistance, increasing maintenance and time costs. Therefore, this invention provides a self-cleaning method for cleaning the antibacterial module 6. Another embodiment is detailed below. Figures 4-6 As shown, a self-cleaning housing 81 and brush bristles 82 are fixed on the bottom surface of the water distribution plate 4. The bottom surface of the self-cleaning housing 81 has a through-hole 83 for the antibacterial module 6 to move vertically. The top of the antibacterial module 6 has a magnetic block 84 located inside the self-cleaning housing 81. The outer surface of the water distribution valve cover 3 has an electromagnet module 85. When the antibacterial module 6 needs to be cleaned, the antibacterial module 6 on the water distribution plate 4 will be directly below the electromagnet module 85. Then, the electromagnet module 85 switches the current to cyclically attract and repel the magnetic block 84, thereby providing an upward magnetic attraction force and a downward repulsive force to the magnetic block 84, enabling the antibacterial module 6 to move vertically back and forth. When the antibacterial module 6 enters the self-cleaning housing 81, the brush bristles 82 clean the sides of the antibacterial module 6, promptly removing dirt and impurities from the surface of the antibacterial module 6 and maintaining its good antibacterial performance. This contactless driving method eliminates the need to disassemble the water distribution valve. It allows for external movement of the antibacterial module 6 within the water distribution chamber 11 without interfering with the normal operation of the movable water distribution plate 4. The electromagnet module 85 quickly and accurately applies magnetic attraction and repulsion to the magnetic block 84, making the vertical movement of the antibacterial module 6 faster and more sensitive. This efficient driving method completes the cleaning process of the antibacterial module 6 in a shorter time, improving cleaning efficiency and ensuring the dishwasher returns to optimal working condition more quickly, meeting users' needs for efficient cleaning. It also ensures the water distribution valve's seal, preventing water leakage and the entry of external impurities.

[0033] The electromagnet module 85 can be connected to the dishwasher's control system to achieve intelligent cleaning control. It can perform timed cleaning based on factors such as the dishwasher's usage frequency and running time, or it can be set to use a water quality sensor to detect water quality and automatically start the cleaning program when the antibacterial module 6 is detected as needing cleaning, thus improving the level of intelligence and efficiency of cleaning.

[0034] The electromagnet module 85 specifically includes an iron core, a coil wound on the iron core, and a current commutation circuit. When an upward magnetic force is needed, the dishwasher control circuit sends a corresponding control signal to the current commutation circuit, causing the electronic switching element in the current commutation circuit to conduct, and the current flows through the coil in a specific direction. According to Ampere's law, a magnetic field in a specific direction is generated around the coil at this time. This magnetic field interacts with the magnetic block 84 on the top of the antibacterial module 6, generating an upward magnetic force that attracts the antibacterial module 6 to move upward, and the antibacterial module 6 moves into the self-cleaning housing 81 accordingly.

[0035] When a downward repulsive force is needed, the dishwasher control circuit sends a control signal to the current commutation circuit again, causing the electronic switching element to switch on, changing the current direction, which in turn changes the direction of the magnetic field generated by the coil. At this time, the changed magnetic field repels the magnetic field of the magnetic block 84, generating a downward repulsive force that pushes the antibacterial module 6 downward. The antibacterial module 6 extends out of the self-cleaning housing 81 to inhibit bacteria in the water distribution chamber 11.

[0036] In this embodiment, see Figure 5 and Figure 6 As shown, a docking part 86 is provided between the antibacterial module 6 and the magnetic block 84. The docking part 86 establishes a more stable connection between the antibacterial module 6 and the magnetic block 84. To ensure firmness, the antibacterial module 6 and the magnetic block 84 are further fixed to the docking part 86 with glue, so that the antibacterial module 6 and the magnetic block 84 can be tightly combined. Under the action of the electromagnet module 85, when the magnetic block 84 moves due to magnetic attraction or repulsion, it can more reliably drive the antibacterial module 6 to move together. The gravity of the antibacterial module 6 and the repulsive force of the electromagnet module 85 will form a downward force on the antibacterial module 6. The docking part 86 is provided with a limiting protrusion 861 to restrict the antibacterial module 6 from detaching from the self-cleaning shell 81, thus limiting the range of movement of the antibacterial module 6.

[0037] See Figure 4 As shown, the self-cleaning housing 81 is arranged around the antibacterial module 6 according to its shape, and the self-cleaning housing 81 is provided with mounting ears 811 on its outside. The self-cleaning housing 81 is firmly fixed to the water distribution plate 4 by means of screws or other fixing methods to prevent the self-cleaning housing 81 from being displaced or falling off due to water flow impact or machine vibration during the operation of the dishwasher.

[0038] Preferably, the edge of the through-hole 83 of the self-cleaning housing 81 is provided with a guide protrusion 812 to guide the vertical movement of the antibacterial module 6, and the side of the antibacterial module 6 forms a guide groove 61 that cooperates with the guide protrusion 812. When the electromagnet module 85 applies a force to the magnetic block 84 to move the antibacterial module 6 up and down, the cooperation of the guide protrusion 812 and the guide groove 61 ensures that the antibacterial module 6 moves along a predetermined straight trajectory, avoiding shaking, deviation, or jamming during movement. This allows the bristles 82 to always accurately and thoroughly clean the side of the antibacterial module 6, improving the cleaning effect and efficiency.

[0039] When the antibacterial module 6 moves vertically back and forth under the action of the electromagnet module 85, the space inside the self-cleaning housing 81 changes. See Figure 4 As shown, the self-cleaning housing 81 is provided with an air pressure balance hole 813 on its side. As the antibacterial module 6 moves, the air pressure inside the housing will constantly change, which may create resistance and affect the smoothness of the movement of the antibacterial module 6. The air pressure balance hole 813 can keep the air pressure inside and outside the self-cleaning housing 81 balanced, ensuring that the antibacterial module 6 is not disturbed by air pressure changes during movement, and can move vertically smoothly and quickly. This ensures that the bristles 82 can clean the antibacterial module 6 efficiently, improving the self-cleaning effect and efficiency.

[0040] For details, see Figures 1-3 As shown, the water distribution drive mechanism 5 includes a drive motor 51 fixed on the water cup 1 and a drive shaft 52 connected to the output end of the drive motor 51. The drive shaft 52 extends into the water distribution chamber 11. A pivot 42, which is connected to the drive shaft 52, is located at the center of the bottom surface of the water distribution plate 4. The drive motor 51 can directly provide stable and precise power output. Through the drive shaft 52 and the pivot 42 at the center of the bottom surface of the water distribution plate 4, precise control of the rotation of the water distribution plate 4 is achieved. This allows the water distribution plate 4 to accurately adjust the position of the diversion hole 41 and precisely distribute the water flow pumped by the washing pump to each water path according to different washing mode requirements. Whether it is a powerful wash, a standard wash, or an energy-saving wash, the accuracy and stability of water flow distribution can be guaranteed, thereby achieving efficient cleaning of tableware under different washing modes and improving the cleaning performance and adaptability of the dishwasher.

[0041] See Figure 3 and Figure 4 As shown, the water distribution chamber 11 has a spiral upward structure. When water enters the water distribution chamber 11, it will flow along the spiral path, avoiding direct impact on the water distribution plate 4 and other components. The pivot 42 of the water distribution plate 4 is coaxial with the water distribution chamber 11, and a rotatable flow-dispersing wheel 43 is provided on the pivot 42. The antibacterial module 6 is located on the outer side of the flow-dispersing wheel 43.

[0042] As water flows through the spirally upward-facing water distribution chamber 11, the rotation of the turbulence wheel 43 continuously agitates the flow. Water that might otherwise flow along a relatively fixed path changes direction under the influence of the turbulence wheel 43, passing over the antibacterial module 6 more frequently. This ensures that even at higher flow rates, more water comes into full contact with the antibacterial module 6, allowing it to more effectively inhibit bacterial growth. The rotation of the turbulence wheel 43 creates a turbulent flow, increasing its intensity. This turbulence disrupts the laminar flow characteristics, making the mass transfer process between the water and the antibacterial module 6 more intense. Bacteria are more dispersed in the water, increasing the probability of contact between bacteria and the antibacterial module 6, thus reducing the bacterial content in the recycled water. This ensures the hygiene and safety of the washed tableware and reduces the potential threat of bacterial residue to human health.

[0043] Furthermore, the water distribution chamber 11 of the water cup 1 is equipped with an ultrasonic transducer located below the antibacterial module 6. Ultrasonic waves generate vibrations and impacts on the water flow, making it more active. The ultrasonic waves generated by the transducer form tiny bubbles in the water. These bubbles, through continuous oscillation and growth, burst instantly upon reaching a certain size, releasing enormous energy. This energy acts on the bottom surface of the antibacterial module 6 in the form of microjets and shock waves. The microjets can directly impact the dirt and bacteria on the bottom surface of the antibacterial module 6, peeling them off and achieving efficient cleaning.

[0044] The antibacterial module 6 is preferably a nano-silver ion module. The nano-silver ion module exerts its antibacterial effect primarily through the release of silver ions and their interaction with bacteria. Nano-silver ions possess extremely strong antibacterial capabilities, exhibiting significant inhibitory and killing effects on various bacteria, fungi, viruses, and other microorganisms. The antibacterial module 6 is block-shaped or cylindrical. These block-shaped or cylindrical nano-silver ion modules have a certain volume and surface area, enabling them to continuously release silver ions. During dishwasher use, with the continuous rinsing and circulation of water, nano-silver ions can be stably released into the water, exerting an antibacterial effect for a prolonged period. This long-lasting antibacterial effect reduces the chance of bacteria regrowth in the circulating water, ensuring that the dishwasher maintains good cleaning hygiene conditions during multiple uses, eliminating the need for frequent replacement of the antibacterial module 6, and reducing operating costs and maintenance frequency.
