DETAILED DESCRIPTION

[0034] Metal ions such as silver or zinc have a wide spectrum of bactericidal functions. By carrying silver or zinc ions into glass or zeolite particles with sustained-release properties, the long-term bactericidal function of silver ions can be ensured. The sustained-release antibacterial particles need to be in a water environment to exert their unique effects. The dishwasher's circulating water system provides sufficient water conditions, and the washing water and residual water that cannot be drained from the water cup just meet the conditions; in addition, sustained-release antibacterial particles are added to the water cup. During the washing process of the dishwasher, some of the released silver ions are brought into the dishwasher cavity by the water flow, and at the same time have a certain bactericidal effect on the cavity and tableware.

[0035] Among them, the silver ion antibacterial material can only perform contact sterilization on the surface of the component using the antibacterial material, but it is ineffective against water and space, and cannot prevent the residual water in the water cup from becoming moldy and smelly; in addition, the silver ion antibacterial material is prone to failure after long-term washing in the dishwasher environment. The silver ion antibacterial coating, like the antibacterial material, can only perform contact sterilization, and cannot effectively kill the bacteria in the water, and cannot prevent the residual water in the water cup from becoming moldy and smelly. Moreover, the coating is prone to fall off and become ineffective due to long-term hot and cold alternation and high water pressure flushing in the dishwasher environment. The material or coating is easily covered and ineffective by contaminants, and is not easy to clean and maintain. The present invention aims to provide a device for effectively sterilizing and deodorizing dishwasher washing water, residual water in the water cup and residue. The antibacterial component is slowly released, so that the sterilization and deodorization have good long-term effectiveness. The antibacterial module is simple to install and maintain, and is easy to clean, with good visualization effect.

[0039] See also Figure 1-Figure 5 The filtering device 10 of the embodiment of the present invention can be used in the washing equipment 100, and can also be used in other equipment that requires antibacterial and filtering.

[0040] The filter device 10 according to the embodiment of the present invention may include a filter element 11 and an antibacterial basket 12. The antibacterial basket 12 may contain an antibacterial medium 13, such as water-soluble sustained-release antibacterial particles.

[0041] Among them, Figure 2 The filter element 11 includes a filter body 111 and a mounting plate 114. The mounting plate 114 is connected to the filter body 111, and the filter body 111 can be used to install the antibacterial basket 12.

[0042] like Figure 2 The antibacterial basket 12 may include a basket body 121 and a connection portion 122, the basket body 121 is connected to the filter element 11 through the connection portion 122, and the basket body 121 has a storage cavity, and the storage cavity can contain the sterilization and antibacterial medium 13. The basket body 121 is provided with a channel 1203, and the channel 1203 connects the inner and outer spaces of the antibacterial basket 12. The antibacterial medium 13 can be discharged through the channel 1203.

[0043] As mentioned above, the antibacterial basket 12 is provided with a connecting portion 122 to mount the basket body 121 on the filter element 11 . Specifically, the connecting portion 122 is respectively connected to the basket body 121 and the mounting plate 114 to connect the basket body 121 to the filter element 11 .

[0044] The antibacterial basket 12 in the present invention may be fixedly connected to the filter element 11 , or the antibacterial basket 12 may be detachably connected to the filter element 11 .

[0045] Optionally, the filter element extends in the up-down direction, and the antibacterial basket is arranged at the lower part of the filter element.

[0046] Optionally, the connection part 122 may be a hook, a screw, glue, etc., and the basket body 121 only needs to be connected to the mounting plate 114 through the connection part 122, and the connection between the basket body 121 and the mounting plate 114 may be a fixed and non-detachable connection, a fixed and detachable connection, etc.

[0047] In the above-mentioned filter device 10, since an antibacterial basket 12 is arranged at the lower part of the filter element 11, the storage cavity of the antibacterial basket 12 can accommodate the antibacterial medium 13 (for example, slow-release antibacterial particles). In this way, when the filter device 10 is installed in the equipment (for example, the filter device 10 is installed in the cavity of the water cup 20 of the washing equipment 100), the bactericidal medium can be slowly dissolved and released into the water, thereby directly killing or inhibiting the reproduction of bacteria and mold in the residual water, making it difficult for odor to be generated in the equipment with the filter device 10, thereby ensuring the health and safety of consumers.

[0048] The mounting plate 114 of the present invention can be horizontally arranged on the inner side of the bottom of the filter body 111, and the connecting portion 122 includes a hook fixedly connected to the basket body 121, and the hook is snap-connected to the mounting plate 114. Of course, a hook can also be provided on the mounting plate 114 to fix the connecting portion 122 (hook) to the mounting plate 114. Similarly, the basket body 121 can be installed on the filter element 11 through the snap-connection.

[0049] Of course, in the present invention, the antibacterial basket 12 can also be installed on the filter element 11 by screw connection, bonding, welding, integral molding, etc.

[0050] Alternatively, if Figure 2 The connecting portion 122 includes: a connecting rod 1221, a hook portion 1222 and a limit block 1223, the connecting rod 1221 is connected to the basket body 121; the hook portion 1222 is connected to the connecting rod 1221; the limit block 1223 is connected to the connecting rod 1221, and the hook portion 1222 is spaced apart from the limit block 1223 in a projection in a direction perpendicular to the connecting rod 1221.

[0051] Among them, when the antibacterial basket 12 is used to connect the filter element 11, the aforementioned hook portion 1222 can be passed through the mounting plate 114 and hooked on the mounting plate 114, and the limit block 1223 can be pressed against the other side of the mounting plate 114, that is, the hook portion 1222 and the limit block 1223 are respectively pressed against the two sides of the mounting plate 114, thereby realizing a stable connection between the connecting portion 122 and the mounting plate 114.

[0052] The antimicrobial basket 12 may include a plurality of connection portions 122 arranged at intervals, thereby achieving stable installation of the antimicrobial basket 12 .

[0053] Optionally, in a projection along the extending direction of the connecting rod 1221 , the hook portion 1222 and the limiting block 1223 are disposed on opposite sides of the connecting rod 1221 .

[0054] Reference Figure 2 The antibacterial basket 12 includes two connecting parts 122, and the two connecting parts 122 are arranged opposite to each other. Figure 2 In the example, one of the connection parts 122 is fully displayed, while the other connection part 122 is partially blocked by the leaking grille. Figure 5 In the figure, two connecting parts arranged opposite to each other are also shown, and the two connecting parts are fully displayed.

[0055] It should also be pointed out that the antibacterial basket 12 in the present invention can be an integrated structure, and the addition of antibacterial medium can be achieved through the upper opening of the antibacterial basket 12 with an integrated structure. The opening at the top of the antibacterial basket can be used to add antibacterial medium, and during use, this opening is covered by the mounting plate.

[0056] Combination Figures 1 to 4 Optionally, the upper half of the basket body 121 is closed or covered by the filter element 11, and a channel 1203 is provided at the lower part of the basket body 121. When water flows through the filter device 10, the water will flow downward to the antibacterial basket 12 after being filtered by the filter element 11. Since the upper half of the antibacterial basket 12 is closed, the water will not directly pass through the antibacterial basket 12, thereby reducing the residue in the antibacterial basket 12 and further improving the antibacterial or sterilization effect.

[0057] Among them, the upper half of the basket body 121 in the present invention is covered by the filter element 11, including but not limited to: the filter body 111 directly covers the upper half of the basket body 121; the filter body 111 does not cover the upper half of the basket body 121, but the filter body 111 is located directly above the basket body 121. In this way, it can be ensured that the water flow will not directly flush the sterilization medium in the basket body 121.

[0058] Of course, the water filtered by the filter element 11 can also flow directly downward into the antibacterial basket 12, which can also achieve the function of the filter device 10 of the present application.

[0059] Optionally, the antibacterial basket includes a plurality of ribs 1202 arranged at intervals along a first direction, and the ribs 1202 extend along a second direction, the first direction and the second direction are perpendicular to each other, and channels 1203 are formed between adjacent ribs 1202. The first direction and the second direction may be perpendicular to the up-down direction.

[0060] The spacing between adjacent ribs 1202 can be set according to specific circumstances. For example, in some examples, the spacing between adjacent ribs 1202 is within 1.5 to 3.5 mm, such as the spacing between adjacent ribs 1202 can be 1.5 mm, 2 mm, 3 mm or 3.5 mm. In this way, the spacing between adjacent ribs 1202 is moderate, so that the cup slag discharge will not be affected due to the spacing between adjacent ribs 1202 being too small, and the slow-release antibacterial particles will not fall out of the storage cavity and enter the water cup 20 or even enter the water pump used for slag discharge due to the spacing between adjacent ribs 1202 being too large.

[0061] In addition, the basket body of the present invention includes a water-leaking grille 1211 and a basket cover 1212, wherein the water-leaking grille 1211 is formed with a channel 1203; the basket cover 1212 covers the water-leaking grille 1211, and a storage cavity is formed between the basket cover 1212 and the water-leaking grille 1211, wherein the connection portion 122 is connected to the water-leaking grille 1211, and the basket cover is arranged between the water-leaking grille and the mounting plate, that is, when the water-leaking grille 1211 is connected to the filter element through the connection portion, the basket cover can be fixed at the same time. Antibacterial medium 13, sterilization medium, etc. can be arranged in the antibacterial basket 12, so as to achieve sterilization and antibacterial of the antibacterial basket 12, and when it is used in a dishwasher, water can be saved.

[0062] Alternatively, if Figure 2 The basket cover 1212 is provided with a notch 1201 adapted to the connecting portion 122, and a portion of the connecting portion 122 is embedded in the notch 1201. The positioning of the basket cover 1212 can be achieved.

[0063] The channel is formed on the water leakage grid 1211, and the water leakage grid 1211 may include the aforementioned ribs, that is, the channel is constructed by the aforementioned multiple ribs. Specifically, the water leakage grid 1211 includes annular ribs and ribs, and the ribs are connected to the annular ribs, and the channel is formed between the ribs. When the filter device 10 is installed in the cavity of the water cup 20 of the washing device 100, the multiple channels 1203 face downward and are close to the bottom of the water cup 20, which is more conducive to the water remaining at the bottom of the water cup 20 to soak into the slow-release antibacterial particles through the multiple channels 1203.

[0064] It can be understood that in the present invention, in order to prevent impurities from falling into the channel 1203 or even falling into the storage chamber and blocking the channel 1203, the water leakage grid 1211 can be arranged at the lower side of the basket cover 1212, and the multiple channels 1203 can be located at the lower side of the water leakage grid 1211, and the basket cover 1212 can cover the water leakage grid 1211 at the positive projection of the water leakage grid 1211. In this way, even if impurities flow into the upper part of the basket cover 1212, it is not easy to fall into the channel 1203. In addition, a certain gap can be left between the bottom end of the water leakage grid 1211 and the inner surface of the bottom of the water cup 20, so as to facilitate the discharge of impurities and prevent impurities from blocking multiple channels 1203.

[0065] Optionally, the lower part of the antibacterial basket in the present invention is in the form of a convex shape in the middle. Optionally, a channel is provided at the lower part of the antibacterial basket. In this way, it is convenient for the water below to pass through the leaking grille 1211, so as to release the sterilization medium and the antibacterial medium. Combined with the main structure of the basket body described above, the leaking grille 1211 is in the form of a convex shape in the middle.

[0066] It should be noted that the shape of the basket body can be set according to specific circumstances, and the shape of the water leakage grid 1211 can be set according to specific circumstances. For example, in some examples, the basket body can be hemispherical, ellipsoidal or cubical, and the water leakage grid 1211 can be hemispherical, ellipsoidal or cubical.

[0067] The leaking grille 1211 and the basket cover 1212 are combined into a basket body of the antibacterial basket 12 . A plurality of slow-release antibacterial particles are placed in the antibacterial basket 12 . The assembled antibacterial basket 12 is mounted on the filter element 11 through the connecting portion 122 .

[0068] A cup-lifting mounting buckle 113 is provided at the bottom of the filter element 11 of the filter device 10. The cup-lifting mounting buckle 113 can be used to lock on the chassis system of the water cup 20 and fix the flat filter screen at the same time to form a complete slow-release antibacterial dishwasher chassis system.

[0069] The main body of the antibacterial basket 12 is a spherical or square shell, which can maximize the space for loading antibacterial particles and reduce the resistance of the antibacterial basket 12 components to water flow during washing and drainage. The basket cover 1212 has no grid structure, which can reduce the risk of slag collection.

[0070] The main part of the antibacterial basket 12 is in the shape of a grid, and the spacing of the leaking grid 1211 is controlled within a certain range (1.5-3.5 mm). If the spacing is too small, it will easily affect the slag discharge of the dishwasher water cup 20. If the spacing is too large, the slow-release antibacterial particles will fall out of the antibacterial basket 12 and enter the water cup 20 or the drainage pump. The leaking grid 1211 is fixed in direction and should be parallel to the drainage water flow direction in the chassis system of the water cup 20 after assembly to avoid slag on the grid to the greatest extent.

[0071] The leaking grille 1211 and the basket cover 1212 in the present invention can be fixed by the aforementioned notch structure. Of course, they can also be connected together by other structures. For example, the leaking grille 1211 and the basket cover 1212 are connected and fixed by snap connection, threaded assembly, ultrasonic or hot melt welding and other processes.

[0072] In the present invention, the bottom of the filter body 111 has an opening, and the mounting plate 114 is disposed in the opening and in a direction perpendicular to the axis of the opening.

[0073] Optionally, the basket cover 1212 is formed with an arc surface facing the filter element. In this way, when filtering through the filter body 111, larger particles of impurities can be retained in the first filter cavity, which can prevent the larger particles of impurities from affecting the filtering of the water cup 20 with the filter device 10 and prevent large particles from blocking the channel 1203. In addition, the setting of the arc surface can make the impurities falling on the arc surface slide out from the arc surface, thereby reducing the risk of slag hanging.

[0074] It should be noted that the arc surface can be a circular arc surface or an elliptical arc surface, which can be set according to specific circumstances.

[0075] In some embodiments, the antibacterial basket 12 is a net bag fixed to the bottom of the filter body 111. The first opening 1111e is connected to the first filter cavity. In this way, the antibacterial basket 12 can be fixed in a simple manner, and the space occupied by the antibacterial basket 12 is small. In addition, the antibacterial basket 12 in the form of a net bag has a simple structure and a wide source, and its cost is low.

[0076] In some embodiments, the antibacterial basket 12 is detachably connected to the bottom of the filter body 111. In this way, the installation and removal of the basket cover 1212 are facilitated.

[0077] In some embodiments, the sustained-release antibacterial particles include a carrier. A plurality of ions are dispersed on the surface of the carrier or inside the carrier. The size of the carrier is larger than the size of the channel 1203. A plurality of ions include silver ions and / or zinc ions. In this way, the ions in the sustained-release antibacterial particles can be slowly dissolved in water to slowly release silver ions (Ag+) and / or zinc ions (Zn+) in water. Among them, silver ions (Ag+) can strongly adsorb the sulfhydryl (-SH) on the protease in the bacterial body, and quickly combine with it to destroy the protease of the bacterial body, making it unable to breathe, losing activity, and causing bacterial death. And when the bacteria are killed by silver ions (Ag+), the silver ions are freed from the bacterial corpse and then contacted with other colonies, and the above process is repeated over and over again to form a persistent bactericidal and mildew-proof effect. Among them, a plurality of ions can be loaded on the carrier by an impregnation method. Optionally, a plurality of ions are uniformly dispersed on the surface of the carrier and inside the carrier. In this way, the dispersion of ions on the carrier is high and has a high content.

[0078] The sustained-release antibacterial particles may be irregularly shaped glass or zeolite particles. Preferably, the minimum particle size of the sustained-release antibacterial particles is greater than 1.0 mm.

[0079] In some embodiments, a handle portion 112 is formed on the upper portion of the filter body 111. Thus, the arrangement of the handle portion 112 facilitates grasping and lifting the filter body 111 for observation and cleaning.

[0080] The filter device in the present invention may be a filter device for a dishwasher, wherein: Figure 8 As shown, the filter element may include at least one of a filter cup 11a and a column filter 11b.

[0081] Among them, the filter cup can filter the residue, so that the residue is retained, such as Figure 2 The filter cup 10a can be detachably mounted via the cup mounting buckle 113, so that the slag removal and cleaning of the filter cup 10a are convenient.

[0082] The columnar filter can be used as a further filter for the filter cup, and the filter cup can be placed in the columnar filter.

[0083] Of course, the filter cup and the column filter can be used simultaneously or selectively, and other forms of filtering devices can also be used. Several specific implementations are provided below.

[0084] Example 1

[0085] Combine 1 to Figure 7 The filter cup of the present invention is cup-shaped, with upper and lower ends open to allow water to flow through. A hollow hole is provided on the peripheral wall of the filter cup. The aforementioned mounting plate 114 can be provided at the bottom of the filter cup 11a, and the mounting plate 114 can be provided inside the opening at the bottom of the filter cup. The antibacterial basket can be installed at the bottom of the filter cup through the mounting plate.

[0086] Example 2

[0087] Combination Figure 8 and Fig. 9 The filter element includes a filter cup 11a and a columnar filter 11b. The columnar filter can be columnar and can be set to a hollow structure. The lower part of the filter cup 11a is arranged in the columnar filter. The aforementioned antibacterial basket can be arranged on at least one of the columnar filter 11b and the filter cup 11a, that is, the aforementioned antibacterial basket is arranged on the columnar filter 11b; the aforementioned antibacterial basket is arranged on the filter cup; the aforementioned antibacterial basket is arranged on both the filter cup and the columnar filter.

[0088] Reference Figure 8 and Fig. 9Taking the case where an antibacterial basket is provided at the bottom of the columnar filter as an example, a mounting plate 114 can be provided at the bottom of the columnar filter, and the antibacterial basket 12 can be installed at the bottom of the columnar filter 11b through the mounting plate 114.

[0089] Combination Figures 1 to 7 In the above-mentioned filtration device, since an antibacterial basket 12 is provided at the bottom of the filter body 111, and the storage cavity of the antibacterial basket 12 contains slow-release antibacterial particles, when the filtration device 10 is installed in the cavity of the water cup 20 of the washing device 100, the residual water at the bottom of the cavity of the water cup 20 can be soaked in the slow-release antibacterial particles, and the ions in the slow-release antibacterial particles can be slowly dissolved and released into the water, thereby directly killing or inhibiting the reproduction of bacteria and mold in the residual water in the water cup 20, making it difficult for odor to be generated in the water cup 20 with the filtration device 10, thereby ensuring the health and safety of consumers.

[0090] The filtering device in the present invention includes a planar filter 30 and a microfilter. The planar filter 30 is provided with a second opening 31. The filter body 111 is inserted into the second opening 31 and the upper part of the filter body 111 is against the edge of the second opening 31. The microfilter is sleeved on the lower part of the filter body 111. In this way, layered filtration of water with impurities can be achieved by combining the planar filter 30 and the microfilter. Among them, the mesh of the microfilter is relatively small (smaller than the size of the first filter hole), which can further intercept impurities flowing out of the filter body 111. In addition, the impurities flowing out of the first filter cavity and the impurities flowing out of the second filter cavity can be pumped out of the water cup 20 by a water pump.

[0091] The present invention further provides a washing device, which may include the aforementioned filtering device or the aforementioned filtering device. The washing device 100 may be, for example, a dishwasher, including a table dishwasher, a tank dishwasher, and a cabinet dishwasher.

[0092] Optionally, the washing device comprises a water cup 20 and a filter device, the water cup comprises a circulating water inlet, a circulating water outlet and a drain. The lower part of the filter device extends into the water cup through the circulating water inlet, and the filter device is the filter device described above.

[0093] According to the washing equipment of the embodiment of the present invention, the aforementioned filtering device is provided, and antibacterial and bactericidal media can be filled in the antibacterial basket. When the antibacterial and bactericidal media are released, antibacterial and bactericidal effects can be achieved, thereby effectively improving food safety and avoiding secondary contamination.

[0094] In the present invention, the channel can extend in a direction parallel to the drainage direction of the drain port, that is, during the drainage process, the water flow will flow through the antibacterial basket along the channel. In this way, even if there are impurities in the water, they will not hang on the antibacterial basket, which can effectively improve safety and avoid bacterial growth.

[0095] The washing device 100 of the present invention may further include an inner tank and a water cup 20. The inner tank forms a washing chamber. The bottom of the inner tank is provided with a mounting opening for the water cup 20. The water cup 20 is mounted at the mounting opening of the water cup 20. The filter device is mounted in the water cup 20. The water inlet 1111d is connected to the washing chamber. In this way, the washing water after washing the dishes in the washing chamber can be filtered by the filter device, and the washing water can be fully sterilized. The washing device 100 also includes a spray arm disposed in the washing chamber. The water filtered by the filter device can be pumped to the spray arm by a water pump to wash the dishes placed in the washing chamber.

[0096] The present invention provides a filtering device 10 with slow-release antibacterial particles, and also provides a washing device 100 provided with the filtering device. Taking a dishwasher as an example, the filtering structure of the dishwasher includes a filter element 11, slow-release antibacterial particles, an antibacterial basket 12, a chassis water cup 20 system and a flat filter.

[0097] In the aforementioned antibacterial basket of the present invention, the slow-release antibacterial medium can be prevented. The slow-release antibacterial technology is to prevent the reproduction of microorganisms and play a bactericidal role by slowly releasing metal ions such as Ag+ or Zn2+.

[0098] The slowly-released metal ions, especially silver ions, carry a positive charge, while the bacterial cell wall carries a negative charge. The metal ions are attracted to the bacteria and can rupture the bacterial cell wall or enter the bacteria and combine with sulfhydryl groups, affecting the bacterial reproductive system or causing bacterial death.

[0099] Usually, a solution with an Ag+ concentration of 1ppm or more has a good antibacterial rate. Currently, the Ag+ dissolution amount of sustained-release particles can reach more than 50ppm per day, which can have a very good sterilization and deodorization effect on dishwasher washing water or residual water. The sterilization rate in the water cup 20 reaches 99.99% or more, and the mildew resistance level reaches level 1 or 0.

[0100] The dissolution rate of metal ions in the sustained-release particles is very slow relative to the metal ion content in the particles. The accelerated dissolution life test shows that the sustained-release particles still have good antibacterial and deodorizing effects after 10 years of use in a dishwasher environment. At the same time, the volume of the particles does not decrease by more than 20%, which shows that the sustained-release particles have good long-term effectiveness.

[0101] In the present invention, the antibacterial basket 12 as a whole can also be replaced by a filter bag. As an antibacterial and deodorizing function, the application of slow-release antibacterial technology in the dishwasher water cup 20. The component structure of the antibacterial basket 12 with slow-release antibacterial technology.
