FIG. 13 is a diagram showing an assembly structure of an oil separation mechanism and a retaining ring in the oil filtration device according to the embodiment shown in FIG. The oil filtration device (not shown) according to this embodiment includes an oil separation mechanism 11 and a lid 12. A liquid storage chamber (not shown) is installed in the oil separation mechanism 11 . A liquid inlet passage 13 is installed in the liquid storage chamber. The oil separation mechanism 11 is used to separate oil from the liquid entering the liquid storage chamber. The lid 12 is installed in the liquid storage chamber and covers the liquid entry passage 13. The lid 12 hydraulically opens a liquid entry passage so that liquid enters the liquid storage chamber during cooking.

The oil filtration device of this embodiment is placed in a cooking chamber of a cooking device. In the initial state of cooking, the lid 12 seals the liquid entry passage 13 so that unseparated oil and water liquid does not enter the liquid storage chamber. As the temperature of the juice increases (especially in the process of boiling), the juice in the cooking chamber continues to evaporate, producing water vapor, which increases the local pressure outside the bottom wall of the liquid storage chamber and lowers the liquid level. When the pressure of the juice sufficiently overcomes the downward pressure of the lid body 12, the lid body 12 is raised, and at this time, the liquid inlet passage 13 and the liquid storage chamber are communicated, and the juice mixed with oil and fat is stored in the liquid storage chamber. Enter the chamber. The oil separation mechanism 11 separates oil from the juice in the liquid storage chamber.

Unlike the conventional technology, the oil filtration device of this embodiment can separate oil from juice using the oil separation mechanism 11. In addition, the liquid entry passage 13 is opened and closed by the lid body 12 to prevent the liquid from entering the liquid storage chamber of the oil separation mechanism 11 during the initial state of cooking (no oil or fat is produced in the liquid or a small amount of oil is formed in the liquid). When the liquid is produced and the temperature of the juice rises, especially when it boils (a large amount of fat and oil is produced in the juice), the liquid inlet passage 13 is opened and the liquid is transported to the liquid storage chamber of the oil separation mechanism 11, and the oil is removed. Perform separation. This method can improve the oil separation effect and guarantee the user's physical health.

Note that the liquid entry passage of the present application may be installed at the bottom wall or the bottom of the side wall of the liquid storage chamber. In the following embodiments of the present application, an example will be described in which the liquid entry passage is installed in the bottom wall of the liquid storage chamber.

Here, the oil separation mechanism 11 of this embodiment may be an oil cup, and includes a side wall (not shown) and a bottom wall connected to the side wall 121. This side wall 121 and this bottom wall form a liquid storage chamber. Naturally, in other embodiments, the shape of the oil separation mechanism is not limited, and a structure in which an upper wall or an upper cover is installed in the liquid storage chamber may be used.

Optionally, as shown in FIGS. 1 and 4, a first drain hole a and a second drain hole b are installed in the side wall of the liquid storage chamber of this embodiment, and the first drain hole The hole a communicates the second drain hole b with the liquid storage chamber, and the distance d1 between the first drain hole a and the bottom wall is the distance between the second drain hole b and the bottom wall. smaller than d2.

Since the distance d1 between the first drain hole a and the bottom wall in this embodiment is smaller than the distance d2 between the second drain hole b and the bottom wall, fats and oils in the juice (floating on the liquid surface) ) does not flow out from the first drainage hole a, thereby ensuring that components such as water in the juice (located below the fat and oil) flow through the first drainage hole a and the second drainage hole b. I can guarantee that it will flow out.

Specifically, the sidewalls of the liquid storage chamber include an annular sidewall 101 extending from the bottom wall. A second drain hole b is installed in the annular side wall 101. The side wall of the liquid storage chamber further includes a baffle plate 102 installed within the annular side wall 101. This baffle plate 102 is installed corresponding to the second drain hole b, and a first drain hole a is formed between the baffle plate 102 and the bottom wall. The baffle plate blocks oil and fat and allows components such as water in the juice to flow out from the first drain hole a.

After the liquid in the liquid storage chamber reaches a certain amount, it bypasses the baffle plate 102 and flows out of the liquid storage chamber. Since the density of fats and oils is lower than that of water, most of the fats and oils float near the liquid surface. Meanwhile, the juice in the liquid storage chamber flows out from the bottom. Therefore, oil and fat are left in the liquid storage chamber. By repeating this process, the oil and fat will be concentrated in the liquid storage chamber and the purpose of oil and water separation will be realized.

In one application scene, the d1 range of this embodiment is 0.8mm to 5.2mm, such as 0.8mm, 1mm, 2mm, 3mm, 4mm, 5mm and 5.2mm, which can instantly drain the juice. Ensure that oil and fat spills are minimized. The range of the difference between d2 and d1 is 4mm to 55mm, such as 4mm, 5mm, 10mm, 20mm, 30mm, 40mm, 50mm and 55mm, and the liquid storage chamber has a Ensure there is sufficient space.

Optionally, as shown in FIGS. 1, 2, 3 and 6, the liquid inlet hole 61 and the first engagement provided around the liquid inlet hole 61 in the bottom wall of the liquid storage chamber of this embodiment Department will be established. The first engaging part is installed in the liquid storage chamber, and the space surrounded by the liquid inlet hole 61 and the first engaging part forms a liquid inlet passage.

Specifically, the first engagement portion includes a first baffle plate 62 surrounding the outside of the liquid inlet hole 61 . The first baffle plate 62 is installed in the liquid storage chamber, and a space surrounded by the liquid inlet hole 61 and the first baffle plate 62 forms a liquid inlet passage.

The juice enters the liquid storage chamber through the liquid entry hole 61 and flows along the space surrounded by the first baffle plate 62.

Optionally, as shown in FIGS. 1, 7, 8, and 9, the lid 12 of this embodiment includes a lid main body and a second engaging portion. The lid body covers the liquid inlet hole 61, and the first engaging portion and the second engaging portion are installed together.

Specifically, the lid of this embodiment includes a lid plate 121 and an annular portion 122 extending from the lid plate 121 in the axial direction of the liquid inlet hole 61. The second engagement portion includes a second baffle plate 123 extending from the lid plate 121 along the axial direction of the liquid inlet hole 61 . The annular portion 122 is fitted into the liquid inlet hole 61 , and the second baffle plate 123 and the first baffle plate 62 are installed in mesh with each other along the axial direction of the liquid inlet hole 61 .

The lid plate 121, the annular portion 122, and the second baffle plate 123 are integrally molded.

The annular portion 122 not only realizes a guiding action along the axial direction of the liquid inlet hole 61 with respect to the lid body 12, but also realizes sealing against the liquid inlet hole 61 in the initial state of cooking. The second baffle plate 123 and the first baffle plate 62 are installed in mesh with each other along the axial direction of the liquid inlet hole 61, and when the second baffle plate 123 is in the initial cooking state, the first baffle plate 62 It is realized that the liquid inlet passage portion formed in an enclosed manner is sealed.

Alternatively, in this embodiment, a plurality of first baffle plates 62 with different radii and arranged in an annular manner are installed on the bottom wall of the liquid storage chamber. The plurality of first baffle plates 62 are installed in a nested manner (the first baffle plate 62 with a larger radius is nested outside the first baffle plate 62 with a smaller radius). The lid body 12 includes a plurality of second baffle plates 123 having different radii and arranged in an annular shape. The plurality of second baffle plates 123 are installed in a nested manner (the second baffle plate 123 with a larger radius is nested outside the second baffle plate 123 with a smaller radius). With such a structure, the sealing effect of the lid 12 against the liquid entry passage can be improved.

Optionally, in this embodiment, a gap is formed between the first baffle plates 62 installed adjacently. The first baffle plate 62 is provided with a notch or a through hole for communicating gaps installed adjacent to each other. The liquid inlet hole 61, the gap between the first baffle plate 62, and the notch or through hole in the first baffle plate 62 form a liquid inlet passage.

Furthermore, the notches or through holes of the first baffle plate 62 installed adjacent to each other are installed offset, so that when opening the liquid entry hole 61, the liquid can flow through this gap and this notch or through hole. When sealing the liquid entry hole 61, the offset notches or through holes can improve the sealing effect.

Optionally, in the first baffle plate 62 of this embodiment, the dimension along the radial direction of the liquid inlet hole 61 gradually decreases in the direction from the bottom wall toward the lid plate 121. The dimension of the second baffle plate 123 along the radial direction of the liquid inlet hole 61 gradually decreases in the direction from the cover plate 121 toward the bottom wall. With such a structure, it is possible to reduce the gap between the adjacent first baffle plate 62 and the gap between the adjacent second baffle plate 123 on the premise that the assembly is smooth, thereby preventing liquid from entering. The sealing effect of the lid 12 against the passage can be improved.

Here, the included angle r between the second baffle plate 123 side surface and the cover plate 121 surface may be 90° to 95°, and examples thereof include 90°, 91°, 92°, 93°, 94°, and 95°. It will be done. Further, the included angle r between the first baffle plate 62 side surface and the bottom wall surface may be 90° to 95°, and examples thereof include 90°, 91°, 92°, 93°, 94°, and 95°. The surface of the bottom wall and the surface of the lid plate 121 are parallel.

Optionally, as shown in FIGS. 1 to 13, the first baffle plate 62 of this embodiment is provided with a boss 63 extending toward the central axis of the liquid inlet hole 61. The oil filter device of this embodiment further includes a retaining ring 14 and a spring 15. The retaining ring 14 is fitted outside one end of the first annular portion 122 that is remote from the cover plate 121 . The spring 15 is fitted outside the first annular portion 122, has one end connected to the retaining ring 14, and the other end abuts the boss 63 when the lid body 12 seals the liquid entry passage.

A first fixing part (not shown) is installed at one end of the first annular part 122 away from the cover plate 121, and a second fixing part (not shown) is installed on the inner wall of the retaining ring 14. will be installed.

The retaining ring 14 and the annular portion 122 are fixedly installed, and one end of the spring 15 and the retaining ring 14 are fixedly installed, so that the spring 15 exerts an acting force on the lid body 12 toward the bottom wall. Then, the lid body 12 is pressed downward by the force of the spring 15, sealing the liquid entry passage.

Optionally, the retaining ring 14 of this embodiment is provided with a through hole 141 extending in the axial direction of the liquid entry hole 61. The liquid is discharged into the lid 12 through the through hole 141 due to the action of hydraulic pressure, thereby separating the lid 12 and the liquid entry passage.

The through hole 141 on the retaining ring 14 provides an upward path for the juice. The diameter d3 of the through hole 141 ranges from 0.8 mm to 5.2 mm, such as 0.8 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, and 5.2 mm, to ensure that the flow rate is sufficient. At the same time, food such as meat lumps can be prevented from entering the through hole 141 and blocking the hole.

In the process of boiling, the juice within the cooking device continues to evaporate and water vapor is produced. This increases the local pressure at the bottom of the liquid storage chamber, causing the liquid level to rise, and when the liquid pressure sufficiently overcomes the pressure of the spring 15, the lid 12 is raised. At this time, the liquid entry passage is opened and the liquid mixed with oil and fat enters the liquid storage chamber. When the boiling stops, the force of the spring 15 presses the lid 12 downward, sealing the liquid entry passage, allowing the liquid in the liquid storage chamber to directly circulate, thereby preventing the circulation of fats and oils.

The first fixing part and the second fixing part may be fixed structures such as threads.

The oil filtration device of this embodiment utilizes the characteristics that oil and fat float on the water surface and the characteristics that the liquid level rises when the juice boils, and by providing a U-shaped oil filtration passage, the oil is transferred to the center of the oil separation mechanism. The oil is raised into the liquid storage chamber, filtered by the baffle plate 102, and then circulated, thereby concentrating the oil and fat in the liquid storage chamber to achieve the purpose of oil filtration.

The oil filtration device of this embodiment presses the lid 12 downward by the acting force of the spring 15, and allows the liquid to flow in one direction through a specific liquid entry passage (the first baffle plate 62 and the liquid entry hole 61). Realize. When boiling, the liquid entry passage is opened and the liquid rises from the center of the oil separation mechanism 11. When the boiling stops, the lid body 12 is pressed downward to seal the liquid inlet hole 61, allowing the liquid in the liquid storage chamber to flow directly through the liquid inlet hole 61, and preventing fats and oils from circulating.

Optionally, the lateral gap between the second baffle plate 123 and the first baffle plate 62 may be between 0.04 mm and 0.31 mm, for example 0.04 mm, 0.05 mm, 0.1 mm, 0. .2mm, 0.3mm and 0.31mm, achieving excellent sealing effect and ease of assembly.

The gap between the first baffle plate 62 and the lid plate 121 may be 0.15 mm to 2.1 mm, and examples thereof include 0.15 mm, 0.2 mm, 0.7 mm, 1 mm, 2 mm, and 2.1 mm. It is possible to ensure pressure bonding between the bottom of the second baffle plate 123 and the bottom wall, and improve the sealing effect.
