Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tableware technology, specifically relating to a bowl with an oil-filtering layer. Background Technology
[0002] The way food is served in a cafeteria significantly impacts the dining experience. However, existing bowls typically mix food, oil, and broth together, causing the oil and broth to gradually settle at the bottom, resulting in a large amount of oily and soupy food. Since some diners have different preferences for oily or soupy dishes, this sedimentation can reduce their appetite and lead to a large amount of uneaten or even discarded food, causing unnecessary food waste. Therefore, there is an urgent need for a device that can effectively separate oil and broth from the food to meet the diverse dietary needs of diners and reduce food waste. Utility Model Content
[0003] To overcome the problem in existing rice bowls where oil and broth tend to accumulate at the bottom, forming a mixture of oil and broth, which not only reduces the diner's appetite but also leads to a large amount of food being left uneaten or even thrown away, causing unnecessary food waste, this invention provides a bowl with an oil filter layer. Through the combined use of an upper and lower oil filter plate, excess oil and broth mixture in the food can be effectively separated, and the separated oil and broth is concentrated in an oil collection cup, reducing the impact of oil and broth accumulation on the taste of the food. The overlapping area between the filter holes can change with the rotation angle of the upper oil filter plate, allowing the diner to flexibly control the degree of oil and broth separation according to their individual needs, satisfying different dietary preferences. Furthermore, the upper and lower oil filter plates can be quickly disassembled for cleaning, improving the diner's dining experience and reducing food waste.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: A bowl with an oil filter layer mainly includes a bowl body, an upper oil filter plate, a lower oil filter plate, and an oil collection cup. The bowl body is a hemispherical hollow structure with an open top. A cylindrical, recessed oil collection cup is provided at the center of the bottom of the bowl body. The connection between the top of the oil collection cup and the bottom of the bowl body is formed by an outwardly convex arc surface to form an annular concave platform. Limiting protrusions are symmetrically distributed on the annular concave platform. The upper and lower oil filter plates are both circular disc structures, and their diameters are adapted to the annular concave platform. The edges of the upper and lower oil filter plates are rounded and symmetrically provided with arc-shaped grooves. The arc-shaped grooves match the limiting protrusions. The upper and lower oil filter plates are embedded in the annular concave platform through the arc-shaped grooves and form a detachable connection with the limiting protrusions. Several oil filter holes of the same diameter are correspondingly distributed on the end faces of the upper and lower oil filter plates. The overlap area between the oil filter holes changes with the rotation angle of the upper oil filter plate, thereby realizing dynamic adjustment of the oil-water separation efficiency.
[0005] The upper oil filter tray has a cylindrical first protrusion at the top center and a cylindrical positioning groove at the bottom center. The lower oil filter tray has a second protrusion at the top center that mates with the positioning groove, making it easy for diners to disassemble and take out the upper and lower oil filter trays, and also making it easy to adjust the rotation angle of the upper oil filter tray.
[0006] The oil filter holes are cylindrical with rounded corners, and the inner walls of the oil filter holes are coated with an oleophobic coating with a thickness of 0.1 mm to 0.2 mm to reduce the adhesion of oil in the oil filter holes and improve the oil filtration efficiency.
[0007] The oil collecting cup has a downward-protruding foot at the bottom edge, and the outer diameter of the foot is the same as the outer diameter of the oil collecting cup, which improves the stability of the bowl during use.
[0008] The depth of the annular recess is 0.5mm greater than the total thickness of the upper and lower oil filter discs, so that the two oil filter discs fit together and cooperate with the limiting protrusion to form a stable connection structure, preventing the upper and lower oil filter discs from loosening or shifting during use.
[0009] The beneficial effects of this utility model are:
[0010] This invention, through the combined use of an upper and lower oil filter tray, effectively separates excess oil and broth from food, concentrating the separated oil and broth in a collection cup. This reduces the impact of oil and broth sediment on the taste of the food. The overlapping area between the filter holes can change with the rotation angle of the upper oil filter tray, allowing diners to flexibly control the degree of oil and broth separation according to their individual needs, satisfying different dietary preferences. At the same time, the upper and lower oil filter trays can be quickly disassembled for cleaning, improving the dining experience and reducing food waste. Attached Figure Description

[0018] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.
[0019] This utility model discloses a bowl with an oil filter layer, which mainly includes a bowl body 1, an upper oil filter plate 2, a lower oil filter plate 3, and an oil collection cup 4. Figure 1 As shown, the bowl body 1 is a hemispherical hollow structure with an open top. A cylindrical concave oil collecting cup 4 is set at the center of its bottom. The connection between the top of the oil collecting cup 4 and the bottom of the bowl body 1 is formed by an outwardly convex arc surface to form an annular concave platform 5. The annular concave platform 5 is symmetrically provided with limiting protrusions 6. The limiting protrusions 6 are used to fix the position of the upper oil filter plate 2 and the lower oil filter plate 3 to prevent the upper oil filter plate 2 and the lower oil filter plate 3 from loosening or falling off. At the same time, it is convenient for diners to quickly disassemble and clean the upper oil filter plate 2 and the lower oil filter plate 3. The depth of the annular concave platform 5 is 0.5mm greater than the total thickness of the upper oil filter plate 2 and the lower oil filter plate 3, so that the two can fit tightly. The cooperation between the limiting protrusions 6 and the arc groove 8 further enhances the reliability of the connection.
[0020] Both the upper oil filter tray 2 and the lower oil filter tray 3 are circular discs with diameters matching the annular recess 5. Their edges are rounded and symmetrically decorated with arc-shaped grooves 8, which match the limiting protrusions 6. The arc-shaped grooves 8 are embedded in the annular recess 5 and detachably connected to the limiting protrusions 6, ensuring the upper oil filter tray 2 and the lower oil filter tray 3 are securely mounted on the bottom of the bowl body 1. The end faces of the upper oil filter tray 2 and the lower oil filter tray 3 have several oil-filtering holes 7 of the same diameter. The overlap area between the oil-filtering holes 7 changes with the rotation angle of the upper oil filter tray 2 relative to the lower oil filter tray 3, allowing diners to flexibly adjust the degree of oil-soup separation according to their individual needs. This satisfies the dietary habits of different diners, enhances their dining experience, and reduces food waste.
[0021] Oil filter holes 7 are evenly distributed on the surfaces of the upper oil filter plate 2 and the lower oil filter plate 3, and each hole corresponds to the other. The oil filter holes 7 are cylindrical with rounded corners, and their inner walls are coated with an oleophobic coating. This oleophobic coating is made of, for example, a nanocomposite material containing fluorinated silanes or a silica nanoparticle sol. It can be evenly applied to the inner wall of the oil filter holes 7 using chemical vapor deposition or a sol-gel method. The coating thickness is controlled between 0.1 mm and 0.2 mm, ensuring both the coating's adhesion and the permeability of the oil filter holes 7. This coating has excellent oleophobic properties and high-temperature resistance, maintaining stable performance under high-temperature environments. The diameter of the oil filter holes 7 ranges from 2 mm to 5 mm, and the specific dimensions can be adjusted according to actual usage requirements.
[0022] The upper oil filter tray 2 has a cylindrical first protrusion 10 at the top center and a cylindrical positioning groove 12 at the bottom center. The lower oil filter tray 3 has a second protrusion 11 at the top center that mates with the positioning groove 12. This allows diners to easily disassemble and remove the upper oil filter tray 2 and the lower oil filter tray 3 by rotating them. It also allows for adjustment of the rotation angle of the upper oil filter tray 3, which changes the overlap area of the filter holes between the upper oil filter tray 2 and the lower oil filter tray 3, thereby adjusting the oil filtration speed.
[0023] The oil collecting cup 4 is located at the center of the bottom of the bowl 1 and is used to collect the oil flowing in from the upper oil filter plate 2 and the lower oil filter plate 3. The bottom edge of the oil collecting cup 4 is provided with a downward protruding foot 9. The outer diameter of the foot 9 is the same as the outer diameter of the oil collecting cup 4. The contact line between the edge of the foot 9 and the table provides additional friction, which improves the stability of the bowl 1 during use.
[0024] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principles of this utility model are further explained below in conjunction with specific application scenarios.
[0025] In a canteen setting, diners rotate the upper oil filter tray 2 via the first protrusion 10 at the center of its top, based on the desired oil and broth content of the dish they wish to serve. This causes the upper oil filter tray 2 to shift at an angle relative to the lower oil filter tray 3. As the upper oil filter tray 2 rotates clockwise or counterclockwise, the oil filter holes 7 on the upper and lower oil filter trays 2 and 3 shift relative to each other, changing the overlap area between the holes 7. When the overlap area is larger, the effective flow cross-section of the oil filter holes 7 increases, allowing the oil and broth to flow more easily into the oil collection cup 4, thus achieving rapid separation of large amounts of oil and broth. When the overlap area is smaller, the effective flow cross-section of the oil filter holes 7 decreases, restricting the flow of oil and broth, thus achieving slow separation of small amounts of oil and broth. This allows diners to flexibly control the speed and amount of oil and broth separation according to their needs, meeting the personalized requirements of different diners and effectively reducing food waste.
[0026] Next, the bowl 1 containing the food is placed on the table. Due to gravity, the oil and broth mixture naturally flows to the bottom of the bowl 1 and collects in the area containing the upper and lower oil filter trays 2 and 3. Since both the upper and lower oil filter trays 2 and 3 have oil filter holes 7, and the inner walls of the filter holes 7 are coated with an oleophobic coating, the oil and broth can quickly flow through the filter holes 7 into the oil collection cup 4 under the action of the oleophobic coating, while solid food is effectively blocked above the oil filter trays. The oleophobic coating is made of nanoscale materials with low surface energy, which significantly reduces the adhesion of oil and broth within the filter holes 7, thereby improving the oil-broth separation efficiency. At the same time, the rounded corners of the filter holes 7 further reduce the resistance to the flow of oil and broth, ensuring a smooth separation process.
[0027] The bowl body 1 and the oil collection cup 4 form a stable connection structure through the annular recess 5. The depth of the annular recess 5 is 0.5mm greater than the total thickness of the upper oil filter plate 2 and the lower oil filter plate 3, so that the two can fit tightly together. At the same time, the limiting protrusion 6 further enhances the reliability of the connection by limiting the arc groove 8. This not only prevents the upper oil filter plate 2 and the lower oil filter plate 3 from loosening or shifting during use, but also makes it easy for diners to disassemble and clean the oil filter plate and the bowl body 1.
[0028] After the meal, diners can rotate the upper oil filter tray 2 via the first protrusion 10 until the arc-shaped groove 8 on its edge aligns with the limiting protrusion 6. Then, the upper oil filter tray 2 can be lifted upwards to remove it. Similarly, the lower oil filter tray 3 can be disassembled. Simultaneously, the oil and soup in the oil collection cup 4 can be poured into the swill bucket and washed. The disassembled oil filter trays can be washed separately. Utilizing the oleophobic properties of the coating, only rinsing with water is needed to remove residual oil, avoiding the difficulty of cleaning traditional tableware.
[0029] In summary, this invention solves the problem of oil and soup mixing and settling when food is placed in existing rice bowls. The rotatable adjustment function of the upper oil filter tray 2 allows diners to flexibly control the degree of oil and soup separation according to their individual needs, satisfying the dietary preferences of different diners and effectively reducing food waste. The detachable function of the upper oil filter tray 2 and the lower oil filter tray 3 makes it easy for diners to quickly disassemble, clean and pour out the remaining oil and soup.
[0030] In addition, this invention can also be used as a fruit filter. Since the public is generally accustomed to using ordinary bowls to hold and wash small fruits such as strawberries, grapes, cherries, and blueberries, water will remain on the surface of the washed fruit. This residual water will accumulate at the bottom of the bowl. Fruits at the bottom of the bowl will be soaked in the accumulated water for a long time, which will easily make them soft and mushy, lose their original crisp texture, and affect their appetite and health.
[0031] Before washing the fruit, the user first rotates the first protrusion 10 on the top of the upper oil filter tray 2 to fully align the oil filter holes 7 of the upper oil filter tray 2 and the lower oil filter tray 3, adjusting the overlap area of the oil filter holes 7 to the maximum to ensure unobstructed drainage. Next, the fruit to be washed is placed directly on the surface of the upper oil filter tray 2, and then clean water is poured into the bowl 1 until the water level submerges the fruit. The user can gently shake or stir the bowl 1 to thoroughly wash away the dirt on the surface of the fruit.
[0032] After cleaning, the user pours the wastewater from bowl 1 outwards along its edge. Because the overlapping area of the oil filter holes 7 is at its maximum opening, and the hydrophobic coating on the inner wall of the oil filter holes 7 reduces water adhesion, the wastewater quickly flows out from the aligned oil filter holes 7 and is rapidly drained. After drainage, residual water adhering to the fruit surface flows into the bottom of bowl 1 under gravity and drips through the oil filter holes 7. These water droplets, along with a small amount of residual wastewater, pass through the oil filter holes 7 of the upper oil filter plate 2 and the lower oil filter plate 3, eventually collecting in the oil collection cup 4 at the bottom of bowl 1. Thus, the fruit is completely separated from the accumulated water, effectively preventing the fruit from being soaked in water and affecting its taste and appearance. The drained fruit can be eaten directly from the upper oil filter plate 2. For subsequent cleaning, the user can easily disassemble the entire filter assembly to clean the filter plates and oil collection cup 4 separately, making maintenance convenient.
[0033] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
