Description

Technical Field

[0001] The invention relates to the technical field of dishwashers, and in particular to a dishwasher water diverter valve with antibacterial function and a dishwasher. Background Art

[0002] There are usually three types of sprayers in the dishwasher tank: bottom spray, middle spray and top spray. The bottom spray is located at the bottom of the dishwasher tank, the middle spray is located at the bottom of the upper shelf of the dishwasher, and the top spray is located at the top of the dishwasher tank. The three sprayers work alone or in conjunction with each other to build different cleaning modes. Different cleaning modes correspond to different waterways. The amount of water required for each cleaning mode is different. The water diverter valve can distribute the water flow pumped by the washing pump entering the dishwasher to different waterways according to the preset proportion and direction, ensuring that each part can get enough cleaning water, achieving a balance between water conservation and efficient cleaning.

[0003] In order to better save water and reduce emissions, during the washing process of the dishwasher, part of the washing water will be filtered and sent to the water diversion valve for recycling. However, after the washing water is mixed with food residues, the bacteria in it will multiply wildly, resulting in a high bacterial content in the circulating water. After the final washing, more bacteria will remain on the surface of the tableware, affecting people's health and reducing the cleaning effect of the dishwasher. In addition, the large-scale reproduction of bacteria in the water diversion valve may produce corrosive substances, causing damage to the water diversion valve and other parts of the dishwasher.

DETAILED DESCRIPTION

[0026] The present invention provides a dishwasher water diverter valve and a dishwasher with antibacterial function. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the scope of protection of the present invention.

[0027] See also Figure 1-Figure 3 The present invention provides a dishwasher water diverter valve with an antibacterial function, comprising a water cup 1 with a water diverter chamber 11, a water inlet pipe 2 connected to the water inlet of the water diverter chamber 11, a water diverter valve cover 3 sealed and fixed at the water outlet of the water diverter chamber 11, a water diverter plate 4 arranged in the water diverter chamber 11 and used to control the conduction of a diverter joint 31 of the water diverter valve cover 3, and a water diverter driving mechanism 5 used to drive the water diverter plate 4 to rotate; the water diverter valve cover 3 is coaxially arranged with the water diverter plate 4, the water diverter plate 4 is provided with a diverter hole 41, and an antibacterial module 6 is arranged at the bottom of the water diverter plate 4, and the antibacterial module 6 is used to inhibit the reproduction of bacteria in the water flowing through the water diverter chamber 11.

[0028] When the dishwasher is working, the water pumped by the washing pump enters the water cup 1 with the water diversion cavity 11 through the water inlet pipe 2. The water diversion driving mechanism 5 drives the water diversion plate 4 to rotate. The water diversion hole 41 is provided on the water diversion plate 4. During the rotation process, the position change of the diversion hole 41 controls the flow direction and distribution ratio of the water flow, so as to realize the distribution of water to different waterways under different washing modes.

[0029] In the process of water flowing through the water diversion chamber 11, since the antibacterial module 6 is arranged at the bottom of the water diversion plate 4, when the water contacts the antibacterial module 6, the antibacterial module 6 takes effect to inhibit the reproduction of bacteria in the water. In this way, even the recycled washing water can be effectively controlled in terms of its bacterial content when passing through the water diversion valve. The water diversion valve cover 3 is coaxially arranged with the water diversion plate 4, and cooperates with the water outlet of the water diversion chamber 11 under the rotation adjustment of the water diversion plate 4 to ensure that the water flow after the antibacterial treatment is distributed according to the preset water path, thereby realizing the function of both reasonably distributing the water flow to meet the requirements of different cleaning modes and inhibiting the reproduction of bacteria to ensure the cleaning effect and the safety of equipment components.

[0030] Compared with the prior art, the dishwasher water diversion valve provided by the present invention cleverly utilizes the bottom space of the water diversion plate 4 to set the antibacterial module 6, which can effectively inhibit the bacterial reproduction in the water flowing through the water diversion chamber 11, reduce the bacteria content in the circulating water, thereby reducing the bacteria residue on the surface of the tableware after washing, protecting people's health, and improving the washing effect of the dishwasher. It also avoids the generation of corrosive substances in the water diversion chamber 11, and prolongs the service life of the water diversion valve and other components.

[0031] In one embodiment, see Figure 1As shown, the bottom surface of the water diversion sheet 4 is provided with a limiting edge 71 that matches the shape of the antibacterial module 6, and the limiting edge 71 is provided with two buckle ears 72 that fix the antibacterial module 6 to the bottom surface of the water diversion sheet 4. During the operation of the dishwasher, the impact of the water flow and the rotation of the water diversion sheet 4 may produce a certain force on the antibacterial module 6. The limiting edge 71 can effectively limit the displacement of the antibacterial module 6 to prevent it from affecting the antibacterial effect or the normal operation of the water diversion valve due to shaking or displacement. The two buckle ears 72 firmly fix the antibacterial module 6 to the bottom surface of the water diversion sheet 4, ensuring that the antibacterial module 6 can be stably in the working position under various working conditions, and will not fall off due to the vibration of the machine or the impact of the water flow, thereby ensuring the continuity and reliability of the antibacterial function. When the antibacterial module 6 needs to be replaced, the design of the buckle ears 72 makes the disassembly operation relatively simple, which is convenient for users or maintenance personnel to maintain, and reduces the difficulty of operation and time cost.

[0032] As the dishwasher is used, dirt and other substances that affect its antibacterial performance may adhere to the surface of the antibacterial module 6. The antibacterial module 6 is hidden in the water diversion valve. Disassembling the water diversion valve is not only cumbersome, but may also require professional personnel to perform, increasing maintenance costs and time costs. Therefore, the present invention provides a self-cleaning method for cleaning the antibacterial module 6. Another embodiment is specifically shown in FIG. Figure 4-Figure 6 As shown, a self-cleaning housing 81 and bristles 82 arranged in the self-cleaning housing 81 are fixedly provided on the bottom surface of the water-dividing sheet 4, a through-hole 83 is provided on the bottom surface of the self-cleaning housing 81 for the antibacterial module 6 to move vertically, a magnetic block 84 located in the self-cleaning housing 81 is provided on the top of the antibacterial module 6, and an electromagnet module 85 is provided on the outer surface of the water-dividing valve cover 3. When the antibacterial module 6 is to be cleaned, the antibacterial module 6 on the water-dividing sheet 4 will be directly below the electromagnet module 85, and then the electromagnet module 85 will circulate the magnetic attraction block 84 and the repulsion block 84 by switching the current, thereby providing an upward magnetic attraction force and a downward repulsion force for the magnetic block 84, so that the antibacterial module 6 can move back and forth vertically, and the bristles 82 will clean the side of the antibacterial module 6 when the antibacterial module 6 enters the self-cleaning housing 81, and timely remove the dirt and impurities on the surface of the antibacterial module 6 to maintain its good antibacterial performance. This contactless driving method does not need to disassemble the water diversion valve. It can not only drive the antibacterial module 6 in the water diversion chamber 11 to move externally, but also will not form a line to interfere with the normal operation of the active water diversion plate 4. The electromagnet module 85 can quickly and accurately apply 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 can complete the cleaning process of the antibacterial module 6 in a shorter time, improve the cleaning efficiency, ensure that the dishwasher can be restored to a good working state faster, and meet the user's demand for efficient cleaning. Of course, the sealing of the water diversion valve is also ensured to prevent water leakage and external impurities from entering.

[0033] The electromagnet module 85 can be connected to the control system of the dishwasher to realize intelligent cleaning control. It can perform scheduled cleaning according to factors such as the frequency of use and running time of the dishwasher, or set a water quality detection sensor to detect the water quality, and automatically start the cleaning program when it is detected that the antibacterial module 6 needs to be cleaned, thereby improving the intelligent level 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 attraction is required, the dishwasher control circuit sends a corresponding control signal to the current commutation circuit to turn on the electronic switch element in the current commutation circuit, 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, and the magnetic field interacts with the magnetic block 84 on the top of the antibacterial module 6 to generate an upward magnetic attraction, attracting 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 required, the dishwasher control circuit sends a control signal to the current switching circuit again, causing the electronic switch element to switch to the on state, and the current direction changes, thereby causing the direction of the magnetic field generated by the coil to change accordingly. At this time, the changed magnetic field and the magnetic field of the magnetic block 84 repel each other, generating a downward repulsive force, pushing the antibacterial module 6 to move downward, and the antibacterial module 6 extends out of the self-cleaning housing 81 accordingly to inhibit the water in the water diversion chamber 11.

[0036] In this embodiment, see Figure 5 and Figure 6 As shown, a docking piece 86 is provided between the antibacterial module 6 and the magnetic block 84. The setting of the docking piece 86 establishes a more stable connection between the antibacterial module 6 and the magnetic block 84. To ensure the firmness, the antibacterial module 6 and the magnetic block 84 will be further fixed on the docking piece 86 by 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 is moved by 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 repulsion of the electromagnet module 85 will form a downward force on the antibacterial module 6. The docking piece 86 is provided with a limiting convex edge 861 that limits the antibacterial module 6 from detaching from the self-cleaning housing 81, thereby limiting the movement range of the antibacterial module 6.

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

[0038] Preferably, a guide protrusion 812 for guiding the vertical movement of the antibacterial module 6 is provided at the edge of the through-port 83 of the self-cleaning housing 81, and a guide groove 61 matching with the guide protrusion 812 is formed on the side of the antibacterial module 6. When the electromagnet module 85 applies force to the magnetic block 84 to move the antibacterial module 6 up and down, the cooperation between the guide protrusion 812 and the guide groove 61 can ensure that the antibacterial module 6 moves along a predetermined straight line trajectory, avoiding shaking, offset or jamming during the movement. This enables the bristles 82 to always accurately clean the side of the antibacterial module 6 comprehensively and evenly, thereby improving the cleaning effect and efficiency.

[0039] When the antibacterial module 6 moves back and forth vertically under the action of the electromagnet module 85, the space inside the self-cleaning housing 81 will change. Figure 4 As shown, for this purpose, an air pressure balance hole 813 is provided on the side of the self-cleaning housing 81. As the antibacterial module 6 moves, the air pressure in the housing will change continuously, which may form resistance and affect the smooth movement of the antibacterial module 6. The provision of 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, thereby ensuring that the bristles 82 can efficiently clean the antibacterial module 6, improving the self-cleaning effect and efficiency.

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

[0041] See Figure 3 and Figure 4 As shown, the water diversion chamber 11 is a spiral upward structure. When water flows into the water diversion chamber 11, it will flow along the spiral path to avoid directly impacting the water diversion plate 4 and other components. The pivot 42 of the water diversion plate 4 is coaxial with the water diversion chamber 11 and a rotatable spoiler 43 is provided on the pivot 42. The antibacterial module 6 is located on the outer side of the spoiler 43.

[0042] When the water flows in the water diversion chamber 11 spiraling upward, the rotation of the spoiler 43 will constantly disturb the water flow. The water that might originally flow along a relatively fixed path changes its flow direction under the action of the spoiler 43 and passes through the antibacterial module 6 more frequently. In this way, even when the water flow speed is fast, it can ensure that more water is in full contact with the antibacterial module 6, so that the antibacterial module 6 can more effectively play the role of inhibiting bacterial reproduction. The rotation of the spoiler 43 causes the water flow to form a turbulent state, increasing the degree of turbulence of the water. This turbulent state breaks the laminar flow characteristics of the water flow, making the mass transfer process between the water and the antibacterial module 6 more intense. The distribution of bacteria in the water is more dispersed, thereby increasing the probability of bacteria contacting the antibacterial module 6 and reducing the bacterial content in the circulating water. This ensures the sanitation and safety of the tableware after washing and reduces the potential threat of bacterial residues to human health.

[0043] Furthermore, an ultrasonic transducer is provided in the water-dividing chamber 11 of the water cup 1 below the antibacterial module 6. On the one hand, the ultrasonic wave produces a certain vibration and impact on the water flow, making the water flow more active; the ultrasonic wave generated by the ultrasonic transducer will form tiny bubbles in the water, which will burst instantly when reaching a certain size during the continuous oscillation and growth process, releasing huge 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 the surface to achieve efficient cleaning.

[0044] The antibacterial module 6 is preferably a nano silver ion module. When the nano silver ion module plays an antibacterial effect, it is mainly achieved by the release of silver ions and the interaction with bacteria. The antibacterial ability of the nano silver ion is extremely strong, and there is a significant inhibition and killing effect on microorganisms such as various bacteria, fungi, and viruses. The antibacterial module 6 is block-shaped or cylindrical. The block-shaped or cylindrical nano silver ion module has a certain volume and surface area, and can continuously release silver ions. During the use of the dishwasher, along with the continuous flushing and circulation of the water flow, the nano silver ion can be stably released into the water, and the antibacterial effect is played for a long time. This lasting antibacterial effect reduces the chance of bacteria growing again in the circulating water, ensures that the dishwasher can maintain good cleaning and sanitary conditions during repeated use, and does not need to frequently replace the antibacterial module 6, reducing the use cost and maintenance frequency.
