[0002] As living standards improve, a low-fat diet has become a social consensus. A high-fat diet can lead to a series of cardiovascular and cerebrovascular diseases, such as hypertension, hyperlipidemia, fatty liver, and diabetes.

[0003] When stewing meats such as ribs and chicken, it is often necessary to first mix the meat and water and bring it to a boil (commonly known as blanching), then discard the water and add fresh water to stew. The purpose of blanching is to remove impurities and scum produced by the remaining blood, as well as floating fat, thereby removing the fishy smell from the final processed meat and making it more flavorful.

[0004] Currently, the process of stewing meat usually involves manually removing the fat, which is inefficient. If the meat also needs to be rinsed with cold water, it will seriously affect the taste of the meat. 5. Summary of the Invention

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] In the description of the embodiments of the present invention, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of the present invention. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] The present invention will now be described in detail with reference to specific embodiments.

[0037] In some specific embodiments of the present invention, such as Figure 1 and Figure 2 As shown, this solution provides an oil-water separation device, including: an oil separator 10 and an oil nozzle 20; an oil collection area 12 is formed on the first side 11 of the oil separator 10, and an oil storage area 14 is formed on the second side 13 of the oil separator 10; the oil nozzle 20 is disposed on the oil separator 10 and connects to the oil collection area 12 and the oil storage area 14 respectively; wherein, the oil nozzle 20 extends toward the oil storage area 14 and is used to guide the grease on the oil collection area 12 to the oil storage area 14.

[0038] It should be noted that oil should be minimized, otherwise the stewed soup will be too greasy to eat. The foam that rises to the surface during the initial stewing process is food impurity, which not only affects the taste but also the color and appearance of the food, making it unappetizing, and must also be removed.

[0039] Furthermore, when stewing meat by hand, the water is usually discarded after the first stewing, the meat is rinsed again, and then cold water is added for another stewing. This method of stewing by hand requires reheating the cold water, which wastes energy and time. In addition, the high temperature of the meat being stimulated by the cold water will make the meat tough and affect the taste. During the second stewing process, it is also necessary to constantly skim off the foam and oil by hand, otherwise, more will continue to be produced.

[0040] Based on the problems existing in the stewing of meat 50 mentioned above, the present invention provides an oil separator 10 including an oil collection area 12 and an oil storage area 14. The oil separator 10 is installed in the container of stewing meat 50. As the meat 50 is stewed, the oil from the meat 50 floats on the surface of the water and collects in the oil collection area 12. At this time, the oil is guided to the oil storage area 14 on the oil separator 10 by the oil nozzle 20 connecting the oil collection area 12 and the oil storage area 14. This achieves automatic collection of oil during the stewing of meat 50, reduces cooking operation steps, eliminates the need to simmer the meat 50, improves the taste of stewed meat 50 and the user's cooking experience, and solves the problem of difficulty in manually separating floating oil and foam when stewing meat 50.

[0041] Furthermore, the presence of the oil separator 10 during the stewing process of meat 50 can reduce energy consumption and shorten the stewing time, while also preserving the nutrients in the broth. It is easy to clean and convenient to use, and is easy to produce, process and popularize.

[0042] In a possible implementation, the oil separator 10 is applied to a regular pot, which has a container for holding meat 50 inside, and the oil separator 10 is installed inside the container.

[0043] In a possible implementation, the oil separator 10 is applied to an automatic cooking machine, which is equipped with a container for holding meat 50, and the oil separator 10 is installed inside the container.

[0044] In some possible embodiments of the present invention, the fuel injector 20 has a fuel injection passage 21 inside, with an inlet end 22 at the end of the fuel injection passage 21 facing the oil collection area 12 and an outlet end 23 at the end of the fuel injection passage 21 facing the oil storage area 14; wherein, the cross-sectional area of ​​the fuel injector 20 at the inlet gradually decreases from the inlet end 22 side to the outlet end 23 side.

[0045] Specifically, this embodiment provides an implementation of the oil injector 20. By setting the oil injection path 21 to gradually decrease in size from the oil inlet end 22 to the oil outlet end 23, the oil can more easily enter the oil injection path 21 through the oil inlet end 22 in the oil collection area 12. Under the action of the oil injection path 21 with its gradually decreasing oil inlet cross-sectional area, the oil can quickly pass through the oil injection path 21 and enter the oil storage area 14 from the oil outlet end 23, thereby achieving the separation and storage of the oil produced by the meat 50 during the stewing process.

[0046] In some possible embodiments of the present invention, the oil outlet 23 is provided in an open shape, and the cross-sectional area of ​​the open shape is larger than the minimum cross-sectional area of ​​the oil injection passage 21.

[0047] Specifically, this embodiment provides an implementation of the oil outlet 23, which is configured as an open structure, so that the grease sprayed through the oil outlet 23 can be buffered to a certain extent and sprayed in the direction guided by the open oil outlet 23, which is more conducive to the collection and storage of grease on the oil storage area 14 side of the oil separator 10.

[0048] In some possible embodiments of the present invention, the fuel injector 20 is disposed at the geometric center of the fuel distributor 10; or, a plurality of fuel injectors 20 are arranged on the surface of the fuel distributor 10.

[0049] Specifically, this embodiment provides an implementation method for setting the position of the fuel injector 20 on the surface of the oil separator 10. By setting the position of the fuel injector 20 on the oil separator 10, the optimal effect of guiding the grease from the oil collection area 12 to the oil storage area 14 is achieved.

[0050] In a possible implementation, an oil injector 20 is disposed at the geometric center of the oil distribution shroud 10. The oil injector 20 disposed at the geometric center can achieve the optimal effect of guiding grease from the oil collection area 12 to the oil storage area 14.

[0051] In a possible implementation, multiple fuel injectors 20 are evenly distributed on the surface of the fuel distribution cover 10, and the grease is guided from the oil collection area 12 to the oil storage area 14 through multiple points, thereby achieving the maximum effect of guiding the grease from the oil collection area 12 to the oil storage area 14.

[0052] In some possible embodiments of the present invention, the oil distribution cover 10 further includes: a flange 15, which is disposed on the peripheral wall of the oil distribution cover 10 and extends toward the oil collection area 12; wherein the flange 15 and the inclined surface of the second side 13 surround to form an oil storage area 14; the length of the flange 15 along the direction of the oil injection path 21 is less than the length of the oil injection path 21.

[0053] Specifically, this embodiment provides an implementation of the flange 15. By setting the flange 15 on the peripheral wall of the oil separator 10, the storage capacity of grease in the oil storage area 14 of the oil separator 10 is increased. Furthermore, the flange 15 also allows for a larger contact area between the oil separator 10 and the side wall of the container, ensuring sealing performance and preventing grease from overflowing from the flange 15.

[0054] Furthermore, the height of the fuel injector 20 is set higher than the height of the flange 15 to prevent the water sprayed out during boiling from causing the whole thing to overturn and lose its fuel collection function.

[0055] In some possible embodiments of the present invention, the oil distribution cover 10 forms a drainage surface on the surface of the first side 11 that gradually converges from the peripheral wall toward the fuel injector 20 and is inclined toward the oil storage area 14.

[0056] Specifically, this embodiment provides an implementation of the shape of the oil separator 10 on the first side 11 surface. By forming a corresponding converging structure on the surface of the oil separator 10 on the first side 11, the grease in the oil collection area 12 can gradually gather from the peripheral wall of the oil separator 10 towards the nozzle 20 side under the action of the surface of the first side 11 of the oil separator 10, and enter the oil storage area 14 through the nozzle 20, thereby realizing the collection and storage of grease.

[0057] Furthermore, the converging structure allows the grease on one side of the oil collection area 12 to be guided by the surface shape of the first side 11, making it easier to collect towards the fuel injector 20.

[0058] In some possible embodiments of the present invention, the oil distribution cover 10 forms a drainage surface on the surface of the second side 13, which gradually diverges from the self-injecting nozzle 20 toward the peripheral wall and is inclined toward the oil collection area 12.

[0059] Specifically, this embodiment provides an implementation of the oil separator 10 on the second side 13 surface shape. The oil separator 10 is configured with a gradually diverging surface shape, so that the grease flowing out of the fuel injector 20 can be quickly stored in the oil storage area 14 under the action of the second side 13 surface, avoiding more residue near the fuel injector 20, which would prevent subsequent grease from passing smoothly through the fuel injector 20 and causing accumulation and blockage at the fuel injector 20.

[0060] In some possible embodiments of the present invention, it further includes: an oil separator cap 30, which covers the side of the fuel injector 20 facing the oil storage area 14; wherein, the inner surface of the oil separator cap 30 facing the fuel injector 20 has a groove 31, which is used to guide the grease flowing out of the fuel injector 20 to the oil storage area 14.

[0061] Specifically, this embodiment provides an implementation of an oil separator cap 30. By setting the oil separator cap 30, the grease flowing out of the fuel injector 20 can flow to the oil storage area 14 on the oil separator cover 10 under the action of the oil separator cap 30, thereby preventing the grease from splashing at the fuel injector 20.

[0062] In a possible implementation, the groove 31 in the oil separator cap 30 and the blind hole that matches the shape of the oil outlet end 23 of the nozzle 20 serve as an oil spray deflection tool, allowing the grease to be diverted and flow into the oil collection area 12, preventing it from being sprayed onto the top cover of the container through the nozzle 20.

[0063] In a possible implementation, the fuel distributor cap 30 and the fuel injector 20 are detachably connected, and the connection between the fuel distributor cap 30 and the fuel injector 20 is configured as needed.

[0064] In some possible embodiments of the present invention, a positioning pin 32 is also included, which passes through the oil distribution cap 30 and the oil injector 20 in sequence to maintain the distance between the bottom wall of the groove 31 and the end of the oil injector 20.

[0065] Specifically, this embodiment provides an implementation of a positioning pin 32. By setting the positioning pin 32, a certain gap is formed between the oil distribution cap 30 and the oil outlet end 23 of the oil injector 20. The setting of the gap ensures that the grease can pass through smoothly.

[0066] In a possible implementation, the positioning pin 32 is preferably a self-tapping stainless steel screw. A horizontal through hole or blind hole is opened in the bottom of the oil separator cap 30, and a through hole is opened at the position of the corresponding oil injector 20. The positioning pin 32 locks the positional relationship between the two by passing through the above holes, and ensures that the top of the oil injector 20 has an appropriate distance from the inner top wall of the oil separator cap 30. In this way, an integrated oil-water separation device can be formed.

[0067] In some possible embodiments of the present invention, a lifting part 33 is provided on the side of the oil separator cap 30 away from the oil separator cover 10. The lifting part 33 is used to provide a force application position for pulling the oil separator cap 30 and the oil separator cover 10.

[0068] Specifically, this embodiment provides an implementation of the lifting part 33. The lifting part 33 makes it easier for the user to apply force when removing the oil separator 10, avoiding the need for additional removal mechanisms.

[0069] In some possible embodiments of the present invention, at least the lifting portion 33 is made of heat-insulating material.

[0070] Specifically, this embodiment provides an implementation of the material of the lifting part 33. By setting the lifting part 33 to be made of heat-insulating material, the user can avoid being burned when removing the oil distribution cover 10 through the lifting part 33.

[0071] In a possible implementation, the lifting part 33 is made of heat-insulating and heat-resistant urea-formaldehyde resin.

[0072] In some possible embodiments of the present invention, the oil distribution cover 10 and the oil nozzle 20 are thin-shell integral structures formed by stamping or spinning.

[0073] Specifically, this embodiment provides an implementation method for forming the oil distributor 10 and the oil injector 20. The setting of stamping or spinning reduces the processing difficulty of the oil distributor 10 and the oil injector 20, and facilitates the mass production of the oil distributor 10 and the oil injector 20.

[0074] In some possible embodiments of the present invention, the oil separator 10 and the oil nozzle 20 are made of metal; or, the oil separator 10 and the oil nozzle 20 are made of food-grade elastic material.

[0075] Specifically, this embodiment provides an implementation method for the materials used to make the oil separator 10 and the fuel injector 20. The oil separator 10 and the fuel injector 20 are made of metal materials, which are easy to clean and resistant to high temperatures.

[0076] Furthermore, the oil separator 10 and the oil spray nozzle 20 are made of food-grade elastic material, which improves the quality of the oil separator 10 and the oil spray nozzle 20 and ensures the health of users.

[0077] In a possible implementation, the oil distribution cover 10 and the oil nozzle 20 are made of SUS 304 stainless steel.

[0078] In a possible implementation, the oil separator 10 and the oil nozzle 20 are made of food-grade silicone.

[0079] In some specific embodiments of the present invention, such as Figure 1 and Figure 2 As shown, this solution provides a container with a receiving cavity 40 formed inside the container, which is used to receive the above-mentioned oil-water separation device.

[0080] It should be noted that when selecting a container, the effects of gravity and buoyancy must be taken into account to ensure that when the oil-water separator is stationary, the water level in the container is below the fuel injector 20.

[0081] In some specific embodiments of the present invention, this solution provides a household appliance, including the above-described oil-water separator or the above-described container.

[0082] In one application scenario, when the oil-water separator is placed in a cooking container containing stewed meat 50, it floats freely above the water level. Because the nozzle 20 is a narrow, open-ended tube, the water level remains below the nozzle 20. As the water temperature rises, impurities adhering to the surface of the meat 50, residual blood, and solid fat inside the meat 50 turn into foam and liquid grease floating on the water surface. Due to the structural design of the oil collection area 12, the foam and grease automatically gather at the bottom of the nozzle 20 and accumulate there, forming an oil layer and foam layer of a certain thickness. When the water boils, the force of the boiling pushes the foam and oil out of the nozzle 20. After being blocked by the oil separator cap 30, they flow into the oil storage area 14 and are temporarily stored there. The vertical edge ensures that the boiling force does not cause the oil separator cap 10 to tilt significantly, thus preventing the collected oil from spilling. After boiling, reduce the heat to low. This is a standard procedure for stewing meat (50), allowing the meat to cook faster while minimizing water evaporation and energy consumption. It also prevents vigorous boiling from causing water to overflow into the oil collection area (14) along with the oil and foam. Therefore, ensure the spray nozzle is higher than the flange (15). If the heat is set low enough for intermittent boiling, oil and foam can be separated and collected more effectively. This is easily achieved in automatic cooking machines; simply stir periodically during the low-heat stewing process. This facilitates the overflow of foam and oil while preventing prolonged boiling and water overflow.

[0083] After the stewing process is complete, the entire oil-water separator can be removed by holding the lifting part 33.

[0084] Clearly, this invention fully considers practicality and ease of processing, eliminating the need to discard the water used to boil the meat during cooking (the main purpose is to remove scum and oil), and then add cold water to reheat it. This reduces cooking time, keeps the meat tender and not dry, and also reduces the loss of nutrients in soups.
