DETAILED DESCRIPTION

[0040] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0041] In the description of the embodiments of the present application, "upper", "lower", "top", "bottom", orientation or position relationship is based on the attached Figure 1 It should be understood that these directional terms are only used to facilitate the description of the present application and simplify the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application. For example, please refer to Figure 1 , the up and down directions are Figure 1The direction is indicated by the arrow R1.

[0042] In the related art, the soup is boiled by a cooking utensil, and there is no relevant device for emulsifying the soup in the cooking utensil. The soup is constantly rolled in the cooking utensil to increase the thickness of the soup. However, it takes a long time to make the soup present a good milky thick soup by relying on the boiling and rolling of the soup itself, so as to achieve the purpose of increasing the thickness of the soup. It is found through research that the emulsification and thickness of the soup is related to the state of fat, protein and water in the soup. Meat food will dissolve in substances such as fat and protein during the process of cooking soup. The fat density is small and will float on the top of the soup, presenting a state of oil-water separation. In this state, the soup is relatively light and is often not the thick soup expected by users. However, protein has hydrophilic groups and lipophilic groups. Fat can be combined with the lipophilic groups of protein. The protein combined with fat can be better dissolved in water through the hydrophilic groups, so that the protein combined with fat can be more evenly dispersed in water, presenting an emulsified state of oil-water mixture, thereby improving the thickness of the soup. After a long period of continuous tumbling, the soup can form a thick soup that is close to milky white. This is because the fat gradually combines with the protein during the long boiling and tumbling process. However, during the pure boiling and tumbling process of the soup, the fat and protein combine at a slower rate, resulting in a lower emulsification degree and a slower emulsification rate. The extrusion and collision of fat and protein particles and the size of fat and protein particles have a greater impact on the combination rate of the lipophilic groups of fat and protein.

[0043] In view of this, the present application embodiment provides a cooking utensil, please refer to Figure 1 , Figure 3 to Figure 7 , Fig. 9 and Fig.10 ,as well as Figures 13 to 19The cooking device is formed with a first cavity 101, a second cavity 102 and a jet hole 103 for jetting the soup into emulsified form. The jet hole 103 connects the first cavity 101 and the second cavity 102 so that the soup in the first cavity 101 can flow to the second cavity 102 through the jet hole 103. With such a structural form, on the one hand, the soup enters the smaller jet hole 103 from the larger first cavity 101, and the fat and protein in the soup are squeezed and collided due to the smaller space, which is conducive to the faster combination of the fat and protein. On the other hand, the soup in the first cavity 101 flows through the jet hole 103, causing the soup to produce a relatively high-speed jet phenomenon. The fat and protein in the soup that quickly flows into the jet hole 103 constantly collide and impact with each other, which can reduce the particle size of the fat and protein. The faster collision and impact as well as the smaller particle size are conducive to the rapid combination of the lipophilic groups of the fat and protein. The protein combined with the fat is dissolved in the water through the hydrophilic group, so that an oil-water mixed emulsified state can be formed relatively quickly, so that the soup presents a better emulsification effect, and the thickness of the soup is increased in a shorter time.

[0044] It can be understood that the soup flows from the first cavity 101 to the second cavity 102 through the jet hole 103, and the second cavity 102 is used to receive the soup flowing out of the jet hole. The opening of the jet hole 103 at one end facing the first cavity 101 is the inlet of the jet hole 103, and the opening of the jet hole 103 at one end facing the second cavity 102 is the outlet of the jet hole 103. The soup entering the second cavity 102 can flow back to the first cavity 101 through the jet hole 103.

[0045] For example, the food may be meat food, and during the cooking process, fat and protein may be dissolved from the meat food.

[0046] Exemplarily, food may be placed in the first cavity 101 and / or the second cavity 102 .

[0047] In one embodiment, the soup in the first chamber 101 is heated to boil and generates steam to increase the pressure in the first chamber 101 . The greater pressure forces the soup in the first chamber 101 into the jet hole 103 for emulsification, and the soup flows from the jet hole 103 to the second chamber 102 .

[0048] In one embodiment, please refer to Figure 1 , Figure 3 to Figure 7 , Fig. 9 and Fig.10 ,as well as Figures 13 to 19 The cooking device comprises a cooking body 1 and an emulsifying device 2, wherein the emulsifying device 2 is located in the cooking body 1. The emulsifying device 2 is used to emulsify the soup.

[0049] There are many arrangements of the first cavity 101 and the second cavity 102 .

[0050] In one embodiment, please refer to Figure 1 , Figure 3 to Figure 7 , Fig. 9 and Fig.10 ,as well as Figures 13 to 18 The emulsifying device 2 and the cooking body 1 are arranged to form a first cavity 101. With such a structural form, the emulsifying device 2 plays a certain role in separating the first cavity 101 and the second cavity 102. When the soup in the first cavity 101 boils, a large pressure difference can be generated between the first cavity 101 and the second cavity 102, so that the soup in the first cavity 101 can smoothly flow to the second cavity 102 through the jet hole 103.

[0051] In one embodiment, please refer to Fig.19 , the first cavity 101 can be formed in the emulsifying device 2 .

[0052] In one embodiment, please refer to Figure 1 , Figure 3 to Figure 7 , Fig. 9 and Fig.10 ,as well as Figures 13 to 19 The emulsifying device 2 and the cooking body 1 are arranged to form a second cavity 102. In this structural form, the emulsifying device 2 and the cooking body 1 are arranged to form the second cavity 102, so that the space of the second cavity 102 is larger, the resistance of the jet hole 103 to flow into the second cavity 102 is smaller, and there is enough space in the second cavity 102 to accommodate the soup flowing out of the jet hole 103.

[0053] In one embodiment, the second chamber 102 may be formed in the emulsifying device 2 .

[0054] In one embodiment, please refer to Figure 1 , Figure 3 to Figure 7 , Fig. 9 and Fig.10 ,as well as Figures 13 to 18 The emulsifying device 2 and the cooking body 1 are arranged to form a first cavity 101 and a second cavity 102 .

[0055] In one embodiment, please refer to Fig.10 and Fig.11 , the emulsifying device 2 and the cooking body 1 are arranged to form a jet hole 103, and / or, please refer to Figures 1 to 9 ,as well as Figures 12 to 19 The emulsifying device 2 has a jet hole 103. With such a structural form, the position arrangement of the jet hole 103 has little influence on the cooking body 1, which can reduce the processing difficulty of the cooking body 1.

[0056] In one embodiment, the emulsifying device 2 and the cooking body 1 are arranged to form a first cavity 101 and a second cavity 102 , and a jet hole 103 connecting the first cavity 101 and the second cavity 102 is formed in the cooking body 1 .

[0057] In one embodiment, please refer to Fig.10 and Fig.11 The emulsifying device 2 is formed with a protrusion 21, which protrudes from the side of the emulsifying device 2 facing the cooking body 1. The number of the protrusions 21 is multiple, and the multiple protrusions 21 are arranged along the circumference of the emulsifying device 2. The jet hole 103 formed by the emulsifying device 2 and the cooking body 1 is located between two adjacent protrusions 21. In this structural form, the emulsifying device 2 and the cooking body 1 are formed to form a jet hole 103, and the jet hole 103 is separated by the protrusion 21 protruding toward the cooking body 1, and the soup is jetted by using the space between two adjacent protrusions 21 formed by the emulsifying device 2 and the cooking body 1.

[0058] In one embodiment, please refer to Fig.10 and Fig.11 , the protrusion 21 is in the shape of a tooth.

[0059] In one embodiment, please refer to Fig.10 and Fig.11 , from one end of the protrusion 21 toward the center line of the emulsifying device 2 to one end of the protrusion 21 away from the center line of the emulsifying device 2, the span of the protrusion 21 along the circumference of the emulsifying device 2 gradually decreases. In such a structural form, the farther the protrusion 21 is from the center line of the emulsifying device 2, the smaller the span of the protrusion 21 along the circumference of the emulsifying device 2, the larger the gap between two adjacent protrusions 21 along the circumference of the emulsifying device 2, and the protrusion 21 is generally in a sharp sawtooth shape, so that the protrusion 21 of the emulsifying device 2 is more convenient to process.

[0060] In one embodiment, the span of the protrusion 21 along the circumference of the emulsification device 2 may remain unchanged from one end of the protrusion 21 toward the center line of the emulsification device 2 to one end of the protrusion 21 away from the center line of the emulsification device 2 .

[0061] In one embodiment, please refer to Figure 1 , Figure 3 to Figure 7 , Fig. 9 , Fig.12 as well as Fig.18The emulsifying device 2 includes a solid boss 22 and a separator 23. The separator 23 is connected to the solid boss 22, and the solid boss 22 protrudes from the separator 23 along the axial direction of the jet hole 103. The separator 23, the solid boss 22 and the cooking body 1 are arranged to form a first cavity 101 and / or a second cavity 102. The jet hole 103 passes through the solid boss 22, and / or the solid boss 22 and the cooking body 1 are arranged to form the jet hole 103. With such a structural form, no matter the jet hole 103 passes through the solid boss 22 or the solid boss 22 and the cooking body 1 are arranged to form the jet hole 103, the length of the jet hole 103 is related to the solid boss 22 to a certain extent. Since the solid boss 22 protrudes from the partition 23 along the axial direction of the jet hole 103, the length of the jet hole 103 can be extended as much as possible, which is beneficial for the fat and protein in the soup flowing rapidly in the jet hole 103 to fully collide and impact in the jet hole 103 with a longer length, thereby reducing the particle size of the fat and protein and allowing the lipophilic groups of the fat and protein to combine more quickly.

[0062] In one embodiment, please refer to Figure 5 The solid boss 22 protrudes from the side of the partition 23 facing the first cavity 101 .

[0063] In one embodiment, please refer to Figure 1 , Figure 3 and Figure 4 , Figure 7 to Figure 9 , Fig.12 as well as Fig.18 The solid boss 22 protrudes from the side of the partition 23 facing the second cavity 102 .

[0064] In one embodiment, please refer to Figure 6 , the solid boss 22 passes through the partition 23.

[0065] In one embodiment, please refer to Figure 4 The jet hole 103 penetrates the solid boss 22, and the jet hole 103 is a straight hole. The extension direction of the jet hole 103 intersects with the protrusion direction of the solid boss 22. This can increase the resistance of the soup flowing through the jet hole 103, which is conducive to the impact and collision of fat and protein. For example, please refer to Figure 4 The solid boss 22 protrudes upward from the partition 23, the jet hole 103 is a straight hole, and the axial direction of the jet hole 103 is arranged crosswise with the up-down direction.

[0066] In one embodiment, please refer to Fig.12The solid boss 22 also includes a main platform 221 and an oil separator 222 connected to each other. The jet hole 103 passes through the main platform 221. The oil separator 222 surrounds the main platform 221. The separator 23 is formed with an oil filter platform 231 protruding toward the main platform 221. The oil filter platform 231 is supported below the main platform 221. The oil filter platform 231 has a liquid hole 2311. The liquid hole 2311 is arranged along the circumference of the main platform 221. The oil separator 222 is covered on the oil filter platform 231. The oil separator 222 and the separator The partitions 23 are arranged at intervals, the first cavity 101 includes a main cavity 104 and an oil filter cavity 105, the partition 23, the main table 221, the oil separator 222 and the cooking body 1 are arranged to form the main cavity 104 and / or the second cavity 102, the oil separator 222, the main table 221 and the oil filter table 231 are arranged to form the oil filter cavity 105, the oil filter cavity 105 is located at the inlet end of the jet hole 103, the liquid hole 2311 connects the oil filter cavity 105 with the main cavity 104, and the jet hole 103 connects the oil filter cavity 105 with the second cavity 102.

[0067] In this embodiment, the liquid in the main chamber 104 can flow to the second chamber 102 through the liquid hole 2311, the oil filter chamber 105 and the jet hole 103 in sequence, so that the soup flows through the jet hole 103 to produce jet emulsification. When the soup stops boiling or the boiling degree is low, the soup that enters the second chamber 102 through the jet hole 103 can flow back to the oil filter chamber 105 from the gap between the oil separator ring 222 and the partition 23 and flow from the oil filter chamber 105 to the first chamber 101 through the liquid hole 2311. Since fat is lighter and can float on the top of the soup, the other parts of the soup are filtered by the oil filter. The oil filter cavity 105 and the liquid hole 2311 flow to the first cavity 101, so that the liquid level of the soup in the second cavity 102 drops. When the liquid level of the soup drops to a position where the opening formed by the oil separator ring 222 and the partition 23 that can connect the oil filter cavity 105 and the second cavity 102 is at least partially exposed above the liquid surface of the soup, the soup is difficult to flow to the first cavity 101 through the oil filter cavity 105 and the liquid hole 2311 by siphoning. The soup remaining in the second cavity 102 is mainly the fat floating on the soup, so that the excess fat in the emulsified soup in the second cavity 102 is filtered out. The soup can be emulsified and the fat can be filtered out of the emulsified soup.

[0068] In one embodiment, the emulsification device 2 may not be provided with a solid boss 22, and the partition 23 of the emulsification device 2 is a thin-walled member.

[0069] In one embodiment, please refer to Figures 1 to 9The cooking appliance is formed with a reflux hole 106, which connects the first cavity 101 and the second cavity 102 so that the soup in the second cavity 102 can flow back to the first cavity 101 through the reflux hole 106. The structure of the reflux hole 106 is configured as follows: the sum of the areas of the minimum flow cross sections of all the reflux holes 106 is greater than the sum of the areas of the minimum flow cross sections of all the jet holes 103, and / or the aperture of the reflux hole 106 is greater than the aperture of the jet hole 103. In such a structural form, the larger aperture of the reflux hole 106 and / or the larger sum of the areas of the reflux hole 106 make the resistance of the soup passing through the reflux hole 106 smaller, which is conducive to the soup flowing back to the first cavity 101 more smoothly through the reflux hole 106.

[0070] It is understandable that the location of the return hole 106 is not limited.

[0071] In one embodiment, please refer to Fig. 9 The emulsifying device 2 and the cooking body 1 are arranged to form a reflux hole 106 .

[0072] In one embodiment, please refer to Figures 1 to 8 , the emulsifying device 2 has a reflux hole 106.

[0073] In one embodiment, please refer to Figure 1 , Figure 3 to Figure 7 , Fig. 9 and Fig.10 ,as well as Figures 14 to 18 The first cavity 101 is at least partially located below the second cavity 102 .

[0074] In this embodiment, the soup in the upper second cavity 102 can flow back to the first cavity 101 relatively naturally under the action of gravity, and there is no need to provide additional power for the backflow of the soup.

[0075] In one embodiment, please refer to Figure 3 , the reflux hole 106 is located below the jet hole 103. In this structural form, since the reflux hole 106 is located at a lower position, when the soup enters the second cavity 102 from the jet hole 103, the soup in the second cavity 102 will gather toward the reflux hole 106 at a lower position, which is conducive to the soup in the second cavity 102 to flow back through the reflux hole 106.

[0076] In one embodiment, please refer to Figure 7 When the emulsifying device 2 has a reflux hole 106, the reflux hole 106 is located on the bottom wall of the emulsifying device 2, and the jet hole 103 is located on the side wall of the emulsifying device 2. With such a structural form, the soup in the first chamber 101 flows through the jet hole 103 at a higher position on the side wall and enters the second chamber 102, and the soup in the second chamber 102 gathers at the reflux hole 106 on the bottom wall at a lower position, which is conducive to the reflux of the soup in the second chamber 102.

[0077] In one embodiment, please refer to Fig. 9 When the emulsifying device 2 and the cooking body 1 are surrounded by the reflux holes 106, the reflux holes 106 are arranged along the circumference of the emulsifying device 2. In this structural form, the gap between the emulsifying device 2 and the cooking body 1 is used as the reflux hole 106, and it is not necessary to add additional holes on the emulsifying device 2 or the cooking body 1, which can simplify the structure of the emulsifying device 2 or the cooking body 1.

[0078] In one embodiment, please refer to Fig.13 The cooking body 1 includes a body and a liquid level regulator. The emulsifying device 2 is located in the body, and the emulsifying device 2 and the body are surrounded by a first cavity 101 and / or a second cavity 102. The liquid level regulator is installed on the body, and the liquid level regulator can adjust the liquid level of the first cavity 101 and / or the second cavity 102 so that a liquid level difference is generated between the first cavity 101 and the second cavity 102.

[0079] In this embodiment, the liquid level regulator installed on the main body can adjust the liquid level of the first chamber 101 and / or the second chamber 102. Under the action of the liquid level regulator, a liquid level difference is generated between the first chamber 101 and the second chamber 102. The different liquid level differences between the first chamber 101 and the second chamber 102 cause a pressure difference to be generated between the first chamber 101 and the second chamber 102. Under the action of the pressure difference generated by the liquid level difference, the soup in the first chamber 101 flows to the second chamber 102 through the jet hole 103.

[0080] For example, see Fig.13 The liquid level regulator can be used to heat the soup in the first chamber 101 but not the second chamber 102, or the power of the liquid level regulator to heat the soup in the first chamber 101 is greater than the power to heat the second chamber 102. The soup in the first chamber 101 expands by heating, so that the liquid level of the soup in the first chamber 101 rises, and a liquid level difference is formed between the first chamber 101 and the second chamber 102. The soup in the first chamber 101 flows to the second chamber 102 through the jet hole 103 under the action of the pressure difference caused by the liquid level difference between the first chamber 101 and the second chamber 102.

[0081] Exemplarily, the liquid level regulator can be used to pump the soup in the second chamber 102 or external soup into the first chamber 101 to raise the liquid level of the first chamber 101 , thereby generating a liquid level difference between the first chamber 101 and the second chamber 102 .

[0082] For example, see Fig.13 The first cavity 101 is located on one side of the second cavity 102 along a preset direction, and the preset direction is arranged crosswise with the up-down direction. The angle between the surface where the inlet of the jet hole 103 is located and the horizontal plane is greater than the preset angle, and the preset angle is 30° to 45°.

[0083] In one embodiment, please refer to Figure 1 , Figure 3 to Figure 7, Fig. 9 and Fig.10 ,as well as Figures 14 to 18 The emulsifying device 2 and the cooking body 1 are arranged to form a first cavity 101, and the second cavity 102 is located above the first cavity 101. The soup in the first cavity 101 boils and generates steam, which increases the pressure of the first cavity 101. The greater pressure in the first cavity 101 presses the soup in the first cavity 101 into the jet hole 103 and flows to the second cavity 102 through the jet hole 103.

[0084] In one embodiment, please refer to Fig.15 and Fig.16 The emulsifying device 2 and the cooking body 1 are arranged to form a first cavity 101 and a second cavity 102. The cooking appliance further includes a connecting piece and a shielding piece 3 located in the first cavity 101. The shielding piece 3 is arranged at an interval from the emulsifying device 2. The connecting piece is connected to the shielding piece 3 and the emulsifying device 2 respectively. The space enclosed by the shielding piece 3 and the emulsifying device 2 is connected to the second cavity 102. The soup in the second cavity 102 can flow to the side of the shielding piece 3 away from the emulsifying device 2 through the space enclosed by the shielding piece 3 and the emulsifying device 2. In this structural form, the space enclosed by the shielding member 3 and the emulsifying device 2 is connected to the second chamber 102, and the soup flowing to the second chamber 102 through the jet hole 103 can flow to the space enclosed by the shielding member 3 and the emulsifying device 2. Since the shielding member 3 and the emulsifying device 2 are arranged at intervals, the soup flowing to the space enclosed by the shielding member 3 and the emulsifying device 2 can flow back to the first chamber 101 through the gap between the shielding member 3 and the emulsifying device 2. Due to the existence of the shielding member 3, the soup flowing to the space enclosed by the shielding member 3 and the emulsifying device 2 is connected to the second chamber 102. The space enclosed by the shielding member 3 and the hole of the second chamber 102 are blocked by the shielding member 3, and the soup will not flow from the space enclosed by the connecting shielding member 3 and the emulsifying device 2 and the hole of the second chamber 102 to the second chamber 102. The soup will enter the second chamber 102 from the jet hole 103 not blocked by the shielding member 3 as much as possible to emulsify the soup better. The space enclosed by the connecting shielding member 3 and the emulsifying device 2 and the hole of the second chamber 102 can be set larger so that the soup in the second chamber 102 can flow back to the first chamber 101 better.

[0085] In one embodiment, please refer to Fig.15 and Fig.16 The shielding member 3 is formed with a groove 31 which is recessed downward.

[0086] In one embodiment, please refer to Fig.16 The emulsifying device 2 is partially located in the groove 31, and the shielding member 3 arranged at a distance from the emulsifying device 2 and the emulsifying device 2 are arranged to form a siphon channel. During the reflux of the soup, the fat floating on the soup can be retained in the groove 31 of the shielding member 3, achieving the effect of oil filtering.

[0087] In one embodiment, it is also possible that the cooking appliance does not include the shielding member 3 .

[0088] In one embodiment, please refer to Fig.18 , the number of layers of jet holes 103 is at least one layer, the surface where the entrance of each layer of jet holes 103 is located is the target surface, the preset angle is 30° to 45°, the angle between the tangent plane of the target surface corresponding to the location where the entrance of at least one jet hole 103 is located and the horizontal plane is not greater than the preset angle, and the cooking appliance also includes a lifting device 4 connected to the cooking body 1, and the lifting device 4 is used to drive the emulsification device 2 to rise and fall. In such a structural form, the angle between the tangent plane of the target surface corresponding to the location where the entrance of at least one jet hole 103 is located and the horizontal plane is not greater than the preset angle, and the angle between the tangent plane of the target surface at the entrance position of the jet hole 103 and the upper and lower sides is larger, and the lifting device 4 drives the emulsification device 2 to rise and fall, so that the soup in the first cavity 101 can generate a larger extrusion force at the entrance position of the jet hole 103, and the soup in the first cavity 101 is pressed into the jet hole 103.

[0089] It is understandable that the inlet of the jet hole 103, the first cavity 101, and the second cavity 102 may change as the emulsification device 2 rises or falls. Exemplarily, the inlet of the jet hole 103 is an opening of one end of the jet hole 103 toward the first cavity 101. When the emulsification device 2 descends, the second cavity 102 is above the first cavity 101. When the emulsification device 2 rises, the first cavity 101 is above the second cavity 102.

[0090] It should be noted that the tangent plane is a plane tangent to the curved surface. A plane is a special curved surface, and the tangent plane of a plane is the plane itself.

[0091] In one embodiment, the lifting device 4 may be a pneumatic cylinder or an oil cylinder, and the emulsifying device 2 is driven to rise and fall by extending and retracting the pneumatic cylinder or the oil cylinder.

[0092] In one embodiment, the lifting device 4 may be a screw transmission mechanism driven by a motor.

[0093] It can be understood that the jet holes 103 can be arranged in layers.

[0094] Exemplarily, the number of layers of the jet holes 103 may be at least one layer.

[0095] It should be noted that at least one layer refers to one or more layers.

[0096] For example, see Figure 1 , Figure 3 to Figure 7 , Fig. 9 , Fig.10 , Fig.12 , Fig.13 , Fig.15 , Fig.16 , Fig.18 and Fig.19 , the number of layers of the jet holes 103 is one layer.

[0097] Exemplarily, the number of layers of the jet holes 103 may be at least two.

[0098] When there are multiple layers of jet holes 103, the soup flows through the jet holes 103 layer by layer to be emulsified. For example, when there are at least two layers of jet holes 103, the soup first flows through one layer of jet holes 103 to be emulsified, and the soup emulsified by one layer of jet holes 103 can flow through another layer of jet holes 103 to be emulsified again.

[0099] For example, see Fig.14 and Fig.17 , the number of layers of the jet holes 103 is two.

[0100] In one embodiment, please refer to Fig.19 The emulsifying device 2 and the cooking body 1 are arranged to form a second cavity 102, the first cavity 101 and the jet hole 103 are formed in the emulsifying device 2, and the cooking device further comprises a liquid delivery pump 5, the input end of the liquid delivery pump 5 is communicated with the second cavity 102, and the output end of the liquid delivery pump 5 is communicated with the first cavity 101 to pump the soup in the second cavity 102 to the first cavity 101. In such a structural form, food is placed in the second cavity 102 for cooking, and the soup in the second cavity 102 is pumped to the first cavity 101 of the emulsifying device 2 by the liquid delivery pump 5. The soup in the first cavity 101 is pressed into the jet hole 103 of the emulsifying device 2 under the pumping pressure of the liquid delivery pump 5 for emulsification, and the soup emulsified by the jet hole 103 flows back to the second cavity 102. The soup is circulated and pumped to the jet hole 103 by the liquid delivery pump 5, so that the fat and protein in the soup can continuously collide and impact, thereby quickly achieving emulsification.

[0101] In one embodiment, please refer to Fig.14 and Fig.17 The cooking utensil is formed with an energy-gathering cavity 107, and the number of layers of the jet holes 103 is at least two layers. The jet holes 103 of at least two layers are connected to the energy-gathering cavity 107, and the energy-gathering cavity 107 is located between the two layers of the jet holes 103. The first cavity 101 is connected to the jet holes 103 of one layer, and the second cavity 102 is connected to the jet holes 103 of another layer. With such a structural form, on the one hand, the soup is emulsified through one layer of the jet holes 103 and then enters the energy-gathering cavity 107 for mixing. The mixed soup can enter the jet holes 103 of another layer for emulsification again, thereby improving the emulsification effect. On the other hand, the jet holes 103 are manufactured in two layers, so that the length of the jet holes 103 can be appropriately shortened, thereby reducing the difficulty of processing the jet holes 103.

[0102] In one embodiment, please refer to Fig.14, projected along the direction in which the jet holes 103 of one layer are arranged with the jet holes 103 of another layer, the projection area of ​​the jet holes 103 of one layer and the projection area of ​​the jet holes 103 of another layer are at least partially staggered. Such a structural form can reduce the possibility that the soup flowing out of the jet holes 103 of one layer directly flows out of the jet holes 103 of another layer, increase the resistance of the soup flowing out of the jet holes 103 of one layer to flow to the jet holes 103 of another layer, and the soup flowing out of the jet holes 103 of one layer can fully collide and mix in the energy-gathering cavity 107 before entering the jet holes 103 of another layer for emulsification, thereby obtaining a better emulsification effect.

[0103] In one embodiment, please refer to Fig.14 , the projection area of ​​the jet holes 103 of one layer and the projection area of ​​the jet holes 103 of another layer are at least partially offset in the up-down direction.

[0104] In one embodiment, please refer to Fig.14 and Fig.17 , the jet holes 103 of the corresponding layer between the energy-gathering chamber 107 and the second chamber 102 are the first jet holes 1031, the jet holes 103 of the corresponding layer between the energy-gathering chamber 107 and the first chamber 101 are the second jet holes 1032, and the sum of the minimum flow cross-sections of all the first jet holes 1031 is less than the sum of the minimum flow cross-sections of all the second jet holes 1032. With such a structural form, the soup in the first chamber 101 enters the energy-gathering chamber 107 through the second jet holes 1032 to complete an emulsification, and the emulsified soup in the energy-gathering chamber 107 enters the first jet holes 1031 for emulsification again, and the soup is emulsified by the second jet holes 1032 with a larger sum of areas and then enters the first jet holes 1031 with a smaller sum of areas for emulsification, so that the soup flowing through the first jet holes 1031 can further collide and squeeze, thereby improving the emulsification effect.

[0105] Exemplarily, the area of ​​the minimum flow cross section of the first jet holes 1031 is equal to the area of ​​the minimum flow carrying surface of the second jet holes 1032 , and the number of the first jet holes 1031 is not greater than the number of the second jet holes 1032 .

[0106] In one embodiment, the diameter of the first jet hole 1031 and the diameter of the second jet hole 1032 are both less than 10 mm. The sum of the number of the first jet holes 1031 and the number of the second jet holes 1032 is less than 30 mm.

[0107] In one embodiment, please refer to Figure 3 and Fig. 9The cooking device is formed with an energy-gathering ring 108 located in the first cavity 101, and the jet hole 103 is located on the side of the energy-gathering ring 108 facing the center of the energy-gathering ring 108. The distance between the energy-gathering ring 108 and the center of the energy-gathering ring 108 is the target distance, and the target distance gradually decreases from bottom to top. The jet hole 103 is located at the upper end of the energy-gathering ring 108. With such a structural form, when the soup in the first cavity 101 boils and produces floating steam, the energy-gathering ring 108 that shrinks from bottom to top can gather the floating steam, so that the extrusion energy is concentrated to the upper end of the energy-gathering ring 108, which is roughly where the jet hole 103 is located, so that the soup flowing through the jet hole 103 can be better emulsified.

[0108] In one embodiment, please refer to Figure 3 and Fig. 9 , the energy focusing ring 108 and the jet hole 103 are formed in the emulsification device 2.

[0109] In one embodiment, please refer to Figure 3 and Fig. 9 , the energy focusing ring 108 is formed on the separator 23.

[0110] It is understandable that the cooking appliance may not be provided with the energy focusing ring 108 .

[0111] In one embodiment, please refer to Figure 1 , Figure 3 to Figure 7 , Fig. 9 and Fig.10 ,as well as Figures 12 to 19 , the number of layers of the jet holes 103 is at least one layer, the surface where the entrance of each layer of the jet holes 103 is located is the target surface, the preset angle is 30° to 45°, and the position arrangement of the jet holes 103 of each layer satisfies any one of the following arrangements:

[0112] The angle between the tangent plane of the target surface corresponding to the inlet positions of all the jet holes 103 of the corresponding layer and the horizontal plane is not greater than the preset angle;

[0113] The angle between the tangent plane of the target surface corresponding to the positions of the inlets of all the jet holes 103 of the corresponding layer and the horizontal plane is greater than the preset angle;

[0114] The angle between the tangent plane of the target surface corresponding to the position where the entrance of at least one of the jet holes 103 of the corresponding layer is located and the horizontal plane is not greater than the preset angle, and the angle between the tangent plane corresponding to the position where the entrance of at least one of the jet holes 103 of the corresponding layer is located and the horizontal plane is greater than the preset angle.

[0115] Each item is a positional arrangement relationship of the jet holes 103 , and the jet holes 103 showing these positional arrangement relationships can emulsify the soup.

[0116] It should be noted that the target surface is between the first cavity 101 and the second cavity 102 and is away from the surface of the second cavity 102 .

[0117] It should be noted that when the number of layers of the jet holes 103 is at least two, the target surface corresponding to each layer includes the common surface of each layer between the first cavity 101 and the second cavity 102 and the independent surface of each layer. The common surface is located between the first cavity 101 and the second cavity 102, and there is no energy focusing cavity 107 located between the two layers of jet holes 103 on the side of the common surface facing the first cavity 101 and the side of the common surface facing the second cavity 102.

[0118] For example, see Figure 1 , Figure 3 to Figure 7 , Fig. 9 , Fig.10 , Fig.12 , Fig.13 , Fig.15 , Fig.16 , Fig.18 and Fig.19 The number of layers of the jet holes 103 is one layer, and the target surface where the inlet of the jet holes 103 is located is the surface of the emulsifying device 2 located between the first cavity 101 and the second cavity 102 away from the second cavity 102 .

[0119] For example, see Fig.14 and Fig.15 , there are two layers of jet holes 103, the jet holes 103 in the corresponding layer between the energy-gathering cavity 107 and the second cavity 102 are the first jet holes 1031, and the jet holes 103 in the corresponding layer between the energy-gathering cavity 107 and the first cavity 101 are the second jet holes 1032. The common surface P1 of the corresponding layer of the first jet holes 1031 and the corresponding layer of the second jet holes 1032 is located between the first cavity 101 and the second cavity 102 and away from the second cavity 102, and there is no energy-gathering cavity 107 between the two layers of jet holes 103 on the side of the common surface facing the first cavity 101 and the side of the common surface facing the second cavity 102. The independent surface of the corresponding layer of the first jet hole 1031 is the first surface P2, which is located between the energy focusing cavity 107 and the second cavity 102 and away from the second cavity 102. The independent surface of the corresponding layer of the second jet hole 1032 is the second surface P3, which is located between the energy focusing cavity 107 and the first cavity 101 and away from the second cavity 102. The common surface P1 and the first surface P2 constitute the target surface where the entrance of the first jet hole 1031 of the corresponding layer is located. The common surface P1 and the second surface P3 constitute the target surface where the entrance of the second jet hole 1032 of the corresponding layer is located. The area of ​​the part where the second surface P3 overlaps with the common surface P1 is not calculated repeatedly, and the overlapping part only calculates the corresponding area on the common surface.

[0120] Exemplarily, the number of layers of the jet holes 103 is three or more, the energy focusing cavity 107 is divided into a plurality of sub-cavities, a layer of jet holes 103 is arranged between two adjacent sub-cavities, except for the independent surface of the layer corresponding to the first jet hole 1031 and the independent surface of the layer corresponding to the second jet hole 1032, the independent surfaces of the corresponding layers in the remaining layers of the jet holes 103 are located between the two sub-cavities adjacent to the jet holes 103 of the corresponding layer, and the independent surfaces of the corresponding layers are located at the inlet end of the jet holes 103 of the corresponding layer.

[0121] It is understandable that the angle between the tangent plane of the target surface corresponding to the inlet positions of all the jet holes 103 of the corresponding layer and the horizontal plane is not greater than the preset angle. The tangent plane of the target surface at the inlet position of the jet hole 103 is relatively close to the horizontal plane, and the pressure formed by the steam generated by the boiling soup in the first cavity 101 acting on the jet hole 103 is relatively large, which is conducive to the soup in the first cavity 101 squeezing into the jet hole 103 so that the fat and protein in the soup collide and emulsify.

[0122] It can be understood that the angle between the tangent plane of the target surface corresponding to the position where the inlet of all the jet holes 103 of the corresponding layer is located and the horizontal plane is greater than the preset angle. The tangent plane of the target surface at the position where the inlet of the jet hole 103 is located is closer to the vertical plane, the pressure formed by the steam generated by the boiling soup in the first cavity 101 acting on the jet hole 103 is relatively small, the impact force of the soup flowing into the second cavity 102 through the jet hole 103 is relatively small, and the direction of the soup flowing out of the jet hole 103 is relatively close to the horizontal plane, the risk of soup overflowing is relatively small, and cooking is relatively safe.

[0123] It can be understood that the angle between the tangent plane of the target surface corresponding to the position where the inlet of at least one of the jet holes 103 of the corresponding layer is located and the horizontal plane is not greater than the preset angle, and the angle between the tangent plane corresponding to the position where the inlet of at least one of the jet holes 103 of the corresponding layer is located and the horizontal plane is greater than the preset angle. The tangent plane of the target surface at the position where the inlet of some jet holes 103 is located is closer to the horizontal plane, and the tangent plane of the target surface at the position where the inlet of some jet holes 103 is located is closer to the vertical plane, and the soup in the first cavity 101 can flow into the jet holes 103 from different directions as much as possible for emulsification.

[0124] The shape of the flow cross section of the jet hole 103 is not limited.

[0125] In one embodiment, please refer to Figure 20 to Figure 24 , the shape of the jet hole 103 is any one of the following:

[0126] The jet hole 103 is a straight hole;

[0127] Along the extension direction of the jet hole 103, the area of ​​the flow cross section of the jet hole 103 gradually decreases or changes alternately from the inlet of the jet hole 103 to the outlet of the jet hole 103;

[0128] The center line of the jet hole 103 is a curve;

[0129] The jet hole 103 includes a main hole 1033 and a plurality of branch holes 1034 connected to the main hole 1033 . The inlet of the jet hole 103 is located at the main hole 1033 .

[0130] The shape of the jet hole 103 can be selected according to actual needs.

[0131] When the jet hole 103 is a straight hole, the flow velocity of the soup flowing through the jet hole 103 is faster and the resistance is smaller.

[0132] Exemplarily, the jet hole 103 may be a cylindrical hole extending in a straight line.

[0133] When the center line of the jet hole 103 is a curve, the flow direction of the soup in the jet hole 103 will change, which can increase the flow resistance of the soup in the jet hole 103, so that the fat and protein in the soup can fully collide and impact in the jet hole 103 to improve the emulsification effect in a shorter time.

[0134] It should be noted that the curve may be a relatively smooth curve, the curvature of which changes continuously, or a curve may be a multi-segment bending line.

[0135] For example, see Fig. 20 , the jet hole 103 is bent at 90 degrees.

[0136] See also Fig. 22 , along the extending direction of the jet hole 103, the area of ​​the flow cross section of the jet hole 103 changes alternately from the inlet of the jet hole 103 to the outlet of the jet hole 103. The soup flows alternately between the larger space and the smaller space continuously, so that the fat and protein particles in the soup can collide and impact repeatedly, so as to improve the emulsification effect in a shorter time.

[0137] See also Fig.23 , along the extending direction of the jet hole 103, the area of ​​the flow cross section of the jet hole 103 gradually decreases from the inlet of the jet hole 103 to the outlet of the jet hole 103. During the flow of the soup in the jet hole 103, the space is continuously squeezed and becomes smaller, and the flow rate is accelerated, which is conducive to the collision and impact of fat and protein in the soup, so as to improve the emulsification effect in a shorter time.

[0138] In one embodiment, please refer to Fig.21 , the area of ​​the partial flow cross section of the jet hole 103 increases first and then decreases.

[0139] See also Fig.24 When the jet hole 103 includes a main hole 1033 and a plurality of branch holes 1034 connected to the main hole 1033, the inlet of the jet hole 103 is located at the main hole 1033. The soup flows in through the main hole 1033 of the jet hole 103, and flows from the main hole 1033 to the branch holes 1034 with smaller flow cross-sections, and the soup flowing out of the main hole 1033 is further emulsified by the smaller branch holes 1034.

[0140] In one embodiment, the cross-section of the jet hole 103 may be a regular or irregular shape such as a square, an ellipse or a diamond.

[0141] In one embodiment, the maximum particle size of the fat that can be dissolved in water is the target particle size, and the target particle size is 0.05 mm to 0.15 mm. It can be understood that fat with a particle size not greater than the target particle size can be dissolved in water.

[0142] In one embodiment, a circle with a target particle size as a diameter is a critical circle, an area of ​​the critical circle is a critical area, a preset angle is 30° to 45°, the number of layers of the jet holes 103 is at least one layer, and the sum of the areas of the minimum flow cross sections of all the jet holes 103 corresponding to each layer is a first area, and each layer of the jet holes 103 satisfies any one of the following conditions:

[0147] The third proportional term: the flow cross section of the jet hole 103 of the corresponding layer is circular in shape, the diameters of the flow cross section at any two positions on the center line of the jet hole 103 of the corresponding layer are equal, the ratio of the length of the center line of the jet hole 103 of the corresponding layer to the diameter of the corresponding jet hole 103 is greater than or equal to 1, the surface where the entrance of the jet hole 103 of the corresponding layer is located is the target surface, the target surface is away from the second cavity 102, the target surface includes a first target surface and a second target surface connected to each other, the angle between the tangent plane of the first target surface and the horizontal direction is not greater than the preset angle, the projection area of ​​the first target surface along the up-down direction is the second area, the angle between the tangent plane of the second target surface and the horizontal direction is greater than the preset angle, the area of ​​the second target surface is the third area, among all the jet holes 103 of the corresponding layer, the entrance of at least one jet hole 103 is located at the first target surface, the entrance of at least one jet hole 103 is located at the second target surface, and the ratio of the first area of ​​the corresponding layer to the sum of the second area and the third area is not greater than 30%;

[0148] Fourth proportional term: the surface where the inlet of the jet hole 103 of the corresponding layer is located is the target surface, the target surface is away from the second cavity 102, the target surface includes a first target surface, the angle between the tangent plane of the first target surface and the horizontal direction is not greater than the preset angle, the projection area of ​​the first target surface along the up and down direction is the second area, the inlet of all the jet holes 103 of the corresponding layer is located on the first target surface, and the ratio of the first area to the second area of ​​the corresponding layer is not greater than 10% or not greater than 2%;

[0149] Fifth proportional item: the surface where the inlet of the jet hole 103 of the corresponding layer is located is the target surface, the target surface is away from the second cavity 102, the target surface includes a second target surface, the angle between the tangent plane of the second target surface and the horizontal plane is greater than the preset angle, the area of ​​the second target surface is a third area, the inlet of all the jet holes 103 of the corresponding layer is located at the second target surface, and the ratio of the first area to the third area of ​​the corresponding layer is not greater than 10% or not greater than 2%;

[0150] Sixth proportional item: the surface where the entrance of the jet hole 103 of the corresponding layer is located is the target surface, the target surface is away from the second cavity 102, the target surface includes a first target surface and a second target surface that are connected to each other, the angle between the tangent plane of the first target surface and the horizontal plane is not greater than the preset angle, the projection area of ​​the first target surface along the up and down directions is the second area, the angle between the tangent plane of the second target surface and the horizontal plane is greater than the preset angle, the area of ​​the second target surface is the third area, among all the jet holes 103 of the corresponding layer, the entrance of at least one jet hole 103 is located at the first target surface, the entrance of at least one jet hole 103 is located at the second target surface, and the ratio of the first area of ​​the corresponding layer to the sum of the second area and the third area is not greater than 7% or not greater than 1.5%.

[0151] When the jet holes 103 meet any of these conditions, the soup flowing through each layer of the jet holes 103 can produce a better jet effect, so that the soup flows more quickly in the jet holes 103, promoting the mutual collision and impact of protein and fat particles in the soup, which is beneficial to improving the emulsification effect of the soup in a shorter time.

[0152] It can be understood that the diameter of each jet hole 103 of the corresponding layer is not larger than the target particle size, the soup in the first cavity 101 boils and generates steam, which causes the soup in the first cavity 101 to be pressed toward the jet hole 103, and the fat and protein in the soup collide and impact each other to make the fat particle size no larger than the target particle size, and the fat particles smaller than the target particle size can be better dissolved in water, so that the fat can be better dispersed in water, forming an emulsified state of water and milk blending.

[0153] It can be understood that the area of ​​the minimum flow cross section of each jet hole 103 of the corresponding layer is not greater than the critical area. When the flow cross section of the jet hole 103 is circular, the diameter of the corresponding jet hole 103 is smaller than the target diameter. When the flow cross section of the jet hole 103 is non-circular, fat particles larger than the target particle size are more difficult to pass through the jet hole 103 whose minimum flow cross section area is not greater than the critical area. Therefore, the particle size of the fat particles flowing through this type of jet hole 103 through the jet impact will be smaller than the target particle size, so that the fat is better dissolved in water to form an emulsified state of water and milk.

[0154] It can be understood that the angle between the tangent plane of the first target surface and the horizontal direction is not greater than the preset angle, the tangent plane of the first target surface is close to the horizontal plane, the entrances of all jet holes 103 of the corresponding layer are located on the first target surface, and when the ratio of the first area to the second area of ​​the corresponding layer is not greater than 10% or not greater than 2%, the jet holes 103 of this layer located on the first target surface have a better jet effect.

[0155] In particular, when the ratio of the first area to the second area is not greater than 2%, the jet effect produced by the soup flowing through the jet holes 103 at the inlet on the first target surface is more obvious, and the emulsification effect of the soup is greatly improved in a shorter time.

[0156] Illustratively, the ratio of the first area to the second area may be 0.01%, 0.02%, 0.05%, 0.07%, 0.1%, 0.5%, 1%, 2%, 3%, 5%, 7%, 8% or 10%.

[0157] It is understandable that the boiling soup in the first cavity 101 generates steam to press the soup into the jet hole 103. Since the tangent plane of the first target surface is close to the horizontal plane, the boiling soup and steam in the first cavity 101 exert a relatively high pressure on the entrance of the jet hole 103 on the first target surface and the first surface, which is conducive to the collision and impact emulsification of fat and protein in the soup, but the relatively high pressure makes the soup overflow. In one embodiment, the ratio of the first area to the second area in the fourth proportional term is not less than 0.05%. With such a structural form, appropriately increasing the ratio of the first area to the second area can reduce the force in the first cavity 101 that pushes the soup to flow to the entrance of the jet hole 103, thereby reducing the risk of soup overflow.

[0158] It can be understood that the angle between the tangent plane of the second target surface and the horizontal plane is greater than the preset angle, the tangent plane of the second target surface is close to the vertical plane, the entrance of the jet hole 103 of the corresponding layer is located on the second target surface, and when the ratio of the first area to the third area of ​​the corresponding layer is not greater than 10% or not greater than 2%, the layer of jet holes 103 located on the second target surface has a better jet effect.

[0159] In particular, when the ratio of the first area to the third area is not greater than 2%, the jet effect produced by the soup flowing through the jet holes 103 at the inlet on the second target surface is more obvious, and the emulsification effect of the soup is greatly improved in a shorter time.

[0160] It can be understood that the layer of jet holes 103 whose inlets are located on the second target surface is subjected to a relatively small pressure in the first cavity 101 that pushes the soup to flow toward the jet holes 103 , which is beneficial to reducing the risk of soup overflow.

[0161] It can be understood that in the corresponding layer of jet holes 103, when the entrances of some jet holes 103 are located at the first target surface, and the entrances of some jet holes 103 are located at the second target surface, both the first target surface and the second target surface have a certain influence on the pressure of the soup flowing through the jet holes 103, and the area ratio needs to consider the sum of the second area and the third area, and the corresponding ratio can be appropriately reduced. The ratio of the first area of ​​the corresponding layer to the sum of the second area and the third area is not greater than 7% or not greater than 1.5%, so that this layer of jet holes 103 has a better jet emulsification effect.

[0162] In particular, when the ratio of the first area of ​​the corresponding layer to the sum of the second area and the third area is no more than 1.5%, the jet effect produced by the soup flowing through the jet holes 103 of this layer is more obvious, and the emulsification effect of the soup is greatly improved in a shorter time.

[0163] It can be understood that the cross section of the corresponding layer of jet holes 103 is circular in shape, the diameters of the cross sections at any two positions on the center line of the corresponding layer of jet holes 103 are equal, and the ratio of the length of the center line of the corresponding layer of jet holes 103 to the diameter of the corresponding jet holes 103 is greater than or equal to 1. Such jet holes 103 are relatively slender, and the soup flows rapidly in the slender jet holes 103, which is conducive to the mutual impact of fat and protein in the soup and improves the emulsification effect. The range of each area ratio for such slender holes can be appropriately relaxed.

[0164] For the relatively slender jet holes 103, the ratio of the first area to the second area of ​​the corresponding layer is not greater than 50%, the ratio of the first area to the third area of ​​the corresponding layer is not greater than 50%, or the ratio of the first area to the sum of the second area and the third area of ​​the corresponding layer is not greater than 30%, so that the jet holes 103 of the corresponding layer have a better emulsification effect in a shorter time.

[0165] For example, see Figure 1 , Figure 3 to Figure 6 , Fig. 9 , Fig.12 and Fig.18 The number of layers of the jet holes 103 is one layer, the inlet of the jet holes 103 is located at the first target plane, and the first target plane is parallel to the horizontal plane.

[0166] For example, see Figure 7 , Fig.13 , Fig.15 and Fig.16 The number of layers of the jet holes 103 is one layer, the inlet of the jet holes 103 is located at the second target plane, and the second target plane is perpendicular to the horizontal plane.

[0167] For example, see Fig.14 There are two layers of jet holes 103, the inlet of the first jet hole 1031 is located at the first target surface of the target surface of the corresponding layer, and the inlet of the second jet hole 1032 is located at the first target surface of the target surface of the corresponding layer, and the first target surface is parallel to the horizontal plane.

[0168] For example, see Fig.17There are two layers of jet holes 103, the inlet of the first jet hole 1031 is located at the second target surface of the target surface of the corresponding layer, the second target surface is perpendicular to the horizontal plane, and the inlet of the second jet hole 1032 is located at the first target surface of the target surface of the corresponding layer, and the first target surface is parallel to the horizontal plane.

[0169] For example, see Figures 1 to 9 , Fig.12 as well as Fig.18 , the number of layers of the jet holes 103 shown in the figure is one layer, the flow cross section of the jet holes 103 of the corresponding layer is circular, the diameters of the flow cross sections at any two positions on the center line of the jet holes 103 of the corresponding layer are equal, and the ratio of the length of the center line of the jet holes 103 of the corresponding layer to the diameter of the corresponding jet holes 103 is greater than or equal to 1. The jet holes 103 shown in the figure are relatively slender.
