[0084] In the absence of conflict, the embodiments and technical features in the embodiments of the present application may be combined with each other, and the detailed descriptions in the specific implementation methods should be understood as explanations of the purpose of the present application and should not be regarded as improper limitations on the present application.

[0085] It should be noted that down refers to the direction where the ground is located, and up is the opposite of down. The unit "mm" refers to the international unit millimeter, and the unit "μm" refers to the international unit micrometer. A plurality of quantities includes two and more than two. In the embodiments of the present application, the "upper", "lower", "top", "bottom", and "axial" orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings. It should be understood that these orientation terms are only for the convenience of describing the present application and simplifying 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 a limitation on the present application. The present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0086] In the cooking process of the existing cooking utensils, the boiling time of the soup is small and short, the dissolution of substances such as protein and / or fat is small, and there is a lack of effective emulsification. Water-insoluble substances such as fat cannot be effectively dissolved in water, resulting in the soup not being rich enough.

[0087] Emulsification refers to the dissolution of substances such as protein and / or fat in water. In this way, the soup appears as a thick soup that is almost milky white.

[0088] See also Figures 1 to 29 The embodiment of the present application provides a cooking utensil, which comprises a pot body 2 and an emulsifying device 1 in any one embodiment of the present application. The emulsifying device 1 is used in the cooking utensil.

[0089] See also Figure 1 to Figure 2The emulsification device 1 includes an emulsification shell 11, an emulsification chamber 11a is formed in the emulsification shell 11, and a jet hole 111a is formed at the bottom of the emulsification shell 11. The jet hole 111a connects the emulsification chamber 11a and the external space, and the fluid medium in the external space can be sprayed into the emulsification chamber 11a through the jet hole 111a.

[0090] See also Figure 1 to Figure 2 The pot body 2 includes a cooking cavity 2a, the bottom of the emulsifying shell 11 is located in the cooking cavity 2a, and there is a gap H between the bottom of the emulsifying shell 11 and the bottom surface of the cooking cavity 2a, and the fluid medium in the interval space 2aa between the emulsifying shell 11 and the cooking cavity 2a can be sprayed into the cooking cavity 2a through the jet hole 111a. That is, the space between the part of the emulsifying shell 11 located in the cooking cavity 2a and the cavity surface of the cooking cavity 2a is the interval space 2aa.

[0091] That is, when the emulsifying device 1 is used in the pot body 2, the partition space 2aa is the external space. The emulsifying device 1 is used for making soup, and the fluid medium is a mixture of substances such as fat and / or protein and water.

[0092] Research has found 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 fat, protein and other substances during the cooking process. The fat has a low density and will float on the soup, showing a state of oil-water separation. In this state, the soup is relatively clear, which is often not the thick soup that users expect. However, protein has hydrophilic groups and lipophilic groups. Fat can combine with the lipophilic groups of protein. The protein combined with fat can be better dissolved in water through the hydrophilic group, so that the protein combined with fat can be more evenly dispersed in the water, showing an emulsified state of oil and water, thereby improving the thickness of the soup. After a long period of continuous rolling, the soup can form a thick soup close to milky white, which is due to the gradual combination of fat and protein in the long-term boiling and rolling process of the soup. However, the speed of fat and protein combination is slow during the pure boiling process of the soup, which makes the emulsification degree of the soup low and the emulsification speed slow. Factors such as the extrusion and collision of fat and protein particles and the particle size of fat and protein have a great influence on the binding rate of the lipophilic groups of fat and protein.

[0093] The emulsifying device 1 provided by the present application has a volume of the jet hole 111a that is smaller than the volume of the external space, i.e., the space 2aa. When the fat and protein in the soup flow through the jet hole 111a, the fat and protein continuously collide and impact in the jet hole 111a, thereby reducing the particle size of the fat and protein. The jet hole 111a produces a soup spray and emulsification effect. The spray effect refers to the fluid medium being accelerated by the jet hole 111a and then sprayed into the emulsification chamber 11a. That is, the jet hole 111a refers to a hole that can pass the fluid medium, such as gas and / or liquid, through the hole and form a spray effect. The relatively fast collision and impact of the fluid medium and the smaller particle size are conducive to the rapid combination of the lipophilic groups of fat and protein. The protein combined with fat is dissolved in water through the hydrophilic group, which promotes the protein to wrap the fat, or the fat to wrap the protein or water molecules, so that the emulsified state of oil-water mixture can be formed relatively quickly, so that the soup presents a better emulsification effect, and the consistency of the soup is improved in a relatively short time.

[0094] In one embodiment, please refer to Figure 1 to Figure 2 The emulsifying shell 11 includes a bottom shell 111 and an annular shell 112. The bottom shell 111 is formed with a jet hole 111a. The annular shell 112 surrounds the top of the bottom shell 111 to define an emulsifying chamber 11a together.

[0095] See also Figure 1 to Figure 2 The bottom shell 111 is located in the cooking cavity 2a, and there is a gap H between the bottom shell 111 and the bottom surface of the cooking cavity 2a.

[0096] The cooking utensil provided in the embodiment of the present application can increase the concentration of substances such as fat and / or protein dissolved in the soup through the emulsifying device 1, thereby increasing the thickness of the soup and reducing the time consumed for emulsification of the soup.

[0097] The shape of the flow cross section of the jet hole 111a is not limited. For example, the shape of the flow cross section of the jet hole 111a includes but is not limited to circular, elliptical, polygonal or plum blossom shapes, etc. The circular shape of the flow cross section is easier to process, has low cost and stable molding.

[0098] It should be noted that the flow cross section is a cross section perpendicular to the streamline cluster, such as the fluid medium. When the streamline clusters are not parallel to each other, the flow cross section is a curved surface; when the streamline clusters are straight lines parallel to each other, the flow cross section is a plane.

[0099] In some embodiments, the emulsifying device 1 is placed on the pot body 2 in a removable manner. For example, the emulsifying device 1 is detachably connected to the pot body 2. In this way, it is convenient to put the emulsifying device 1 into or take it out of the pot body 2.

[0100] In one embodiment, please refer to Figure 1 , Figure 2 , Figure 7and Fig.10 The bottom shell 111 includes a first portion 1111 and a second portion 1112 connected to the first portion 1111. The height of the upper surface of the second portion 1112 is higher than the height of the upper surface of the first portion 1111. The first portion 1111 surrounds the outer periphery of the second portion 1112, and the jet hole 111a is formed in the second portion 1112. Specifically, the inner periphery of the first portion 1111 along the radial direction is connected to the outer periphery of the second portion 1112, and the outer periphery of the first portion 1111 along the radial direction is connected to the bottom end of the annular shell 112. In this way, the second portion 1112 is close to the center point of the bottom shell 111. Since the heat near the center point of the bottom shell 111 is usually more concentrated during the heating process, the second portion 1112 is located close to the center point of the bottom shell 111, so that the fluid medium near the second portion 1112 has greater energy, and the collision, acceleration and other movements in the jet hole 111a occur more violently.

[0101] Please note that Figures 2 to 4 and Figure 7 , the straight line extending from the vertical direction of the emulsifying shell 11 and passing through the center point is the axis P, and the direction of the axis P is the axial direction. For example, the emulsifying shell 11 can be a rotating body structure or an axisymmetric structure with the axis P extending from the vertical direction. The radial direction is a direction perpendicular to the axial direction.

[0102] For example, in one embodiment, please refer to Figure 1 to Figure 2 , the center point of the second part 1112 coincides with the center point of the bottom shell 111. The second part 1112 is located in the center area of ​​the bottom shell 111.

[0103] It should be noted that the center point of the bottom shell 111 is the geometric center of the projection of the bottom shell 111 in the horizontal plane. The center point of the second portion 1112 is the geometric center of the projection of the second portion 1112 in the horizontal plane.

[0104] The shape of the projection of the bottom shell 111 in the horizontal plane is not limited. For example, the shape of the projection of the bottom shell 111 in the horizontal plane includes but is not limited to a circle, an ellipse or a polygon, etc. Taking a circle as an example, the center point of the bottom shell 111 is the center of the projection of the bottom shell 111 in the horizontal plane.

[0105] The shape of the projection of the second part 1112 in the horizontal plane is not limited. For example, the shape of the projection of the second part 1112 in the horizontal plane includes but is not limited to a circle, an ellipse or a polygon, etc. Taking a circle as an example, the center point of the second part 1112 is the center of the projection of the second part 1112 in the horizontal plane.

[0106] In one embodiment, please refer to Figure 2 and Figure 7The second part 1112 includes a top wall 11121 and a circumferential wall 11122. The height of the top wall 11121 is higher than the height of the first part 1111. The circumferential wall 11122 surrounds the outer periphery of the top wall 11121. The upper end of the circumferential wall 11122 is connected to the top wall 11121, and the lower end of the circumferential wall 11122 is connected to the first part 1111. The top wall 11121 and the circumferential wall 11122 jointly define a receiving groove 1112a. The fluid medium can be accommodated in the receiving groove 1112a, and the jet hole 111a connects the receiving groove 1112a and the emulsification chamber 11a. The volume of the receiving groove 1112a is smaller than the volume of the emulsification chamber 11a, so that the pressure difference at both ends of the jet hole 111a increases, thereby further accelerating the flow rate and mutual collision of the fluid medium, and accelerating the emulsification process.

[0107] In one embodiment, please refer to Figure 1 to Figure 2 The jet hole 111a penetrates the circumferential wall 11122. That is, both ends of the jet hole 111a face radially. The fluid medium is ejected from the jet hole 111a in the radial direction, accelerating the heat and mass interaction between the fluid medium in the middle area of ​​the emulsification chamber 11a and the fluid medium in the surrounding area, further improving the emulsification efficiency.

[0108] In one embodiment, please refer to Figures 9 to 18 , the thickness of the second portion 1112 along the vertical direction is greater than the thickness of the first portion 1111 along the vertical direction. In this way, the length Z of the jet hole 111a can be extended (see Fig.10 ), a greater pressure difference is formed at both ends of the jet hole 111a, the jet effect is more obvious, and the collision, extrusion and other movements of fat and / or protein in the jet hole 111a are intensified, thereby increasing the binding rate of the lipophilic groups of fat and protein, further accelerating the flow rate of the fluid medium, and making the flushing and emulsification effect more obvious.

[0109] In one embodiment, please refer to Figures 9 and 10 , the first end of the jet hole 111a penetrates the lower surface of the second part 1112, and the second end of the jet hole 111a penetrates the peripheral side of the second part 1112. The fluid medium enters the jet hole 111a from the first end of the jet hole 111a, and is then radially sprayed into the emulsification chamber 11a through the second end of the jet hole 111a. With this design, on the one hand, the length of the jet hole 111a can be significantly increased without significantly increasing the thickness of the second part 1112; on the other hand, the first end of the jet hole 111a penetrates the lower surface of the second part 1112, which facilitates the fluid medium in the spacing space 2aa to enter the jet hole 111a, and the second end of the jet hole 111a penetrates the peripheral side of the second part 1112, so that the fluid medium is sprayed radially, which can well disturb the fluid medium in the emulsification chamber 11a and improve the emulsification effect.

[0110] In one embodiment, please refer to Fig. 9 The number of the jet holes 111a is multiple, and the multiple jet holes 111a are arranged at intervals along the circumferential direction. The multiple jet holes 111a can increase the injection amount of the fluid medium.

[0111] In one embodiment, please refer to Fig. 9 The first ends of all the jet holes 111a are divided into a plurality of annular units, and the first ends of the jet holes 111a of each annular unit are arranged at intervals along the circumferential direction, and the plurality of annular units are set one by one in the radial direction. In this way, the first ends of all the jet holes 111a are arranged in a staggered manner, and the first ends of the jet holes 111a are distributed in a larger range, so that the fluid medium around the second portion 1112 can quickly enter the first ends of each jet hole 111a.

[0112] In one embodiment, please refer to Figures 13 to 15 The second portion 1112 is formed with an auxiliary hole 1112b, one end of the auxiliary hole 1112b is connected to the jet hole 111a, and the other end of the auxiliary hole 1112b passes through the lower surface of the second portion 1112. Without increasing the area of ​​the flow cross section of the first end of the jet hole 111a, the auxiliary hole 1112b can increase the flow rate of the fluid medium entering the jet hole 111a, thereby accelerating the emulsification process.

[0113] For some examples, see Figures 13 to 15 Each jet hole 111a may be connected to at least one auxiliary hole 1112b. For example, some jet holes 111a may be connected to one auxiliary hole 1112b, and other jet holes 111a may be connected to multiple auxiliary holes 1112b. For another example, each jet hole 111a is connected to one auxiliary hole 1112b.

[0114] In one embodiment, please refer to Fig.29 Each jet hole 111a is connected to a plurality of auxiliary holes 1112b, and the plurality of auxiliary holes 1112b connected to the same jet hole 111a are arranged radially at intervals. Exemplarily, one end of the auxiliary hole 1112b is connected to a radially extending portion of the jet hole 111a. Each jet hole 111a corresponds to a plurality of auxiliary holes 1112b, thereby further increasing the amount of fluid medium entering each jet hole 111a.

[0115] In one embodiment, please refer to Fig.11 , Fig.12 and Fig. 27 The two ends of the jet hole 111a respectively penetrate the lower surface of the second part 1112 and the upper surface of the second part 1112. In other words, the fluid medium in the jet hole 111a is ejected in the up and down direction. Such a design can accelerate the mixing of the jet ejected from the jet hole 111a and the fluid medium in the upper part of the emulsification chamber 11a, thereby improving the emulsification efficiency.

[0116] For some examples, see Figure 5 and Fig.11 , the portion between the two ends of the jet hole 111a can extend in a straight line. That is, the jet hole 111a is a straight hole. For example, the jet hole 111a can be a straight hole extending in the radial direction or in the up-down direction. In this way, the flow path of the fluid medium in the jet hole 111a is roughly linear.

[0117] For some examples, see Fig.10 , the portion between the two ends of the jet hole 111a can extend along a curve. That is, the jet hole 111a is a curved hole. For example, the two ends of the curved hole can penetrate the upper end surface and the lower end surface of the second part 1112. For another example, the first end of the curved hole penetrates the lower surface of the second part 1112, and the second end of the curved hole penetrates the peripheral side surface of the second part 1112. In this way, the flow path of the fluid medium in the jet hole 111a is roughly curved. For example, the jet hole 111a includes two intersecting sections, both of which are straight line sections. Then the jet hole 111a is roughly L-shaped.

[0118] In some embodiments, all the jet holes 111a are divided into a plurality of radial units, and the jet holes 111a of each radial unit are arranged in a straight line along the radial direction, and the plurality of radial units are arranged at intervals along the circumferential direction. In this way, the jet holes 111a are distributed over a larger range, so that the fluid medium around the second portion 1112 can quickly enter each jet hole 111a.

[0119] In one embodiment, please refer to Fig.10 and Fig.11 The lower surface of the second portion 1112 and the lower surface of the first portion 1111 together form a plane. With such a design, the emulsifying shell 11 is easy to shape, and when the emulsifying device 1 is taken out of the pot body 2, the emulsifying shell 11 is conveniently and stably placed on other bearing surfaces such as a desktop.

[0120] In one embodiment, please refer to Fig.13 The lower surface of the second part 1112 and the lower surface of the first part 1111 together form a convex arc surface that bulges upward. In this way, the space below the second part 1112 is larger so that more liquid can be collected, and because the heat in the middle area is greater, the liquid can be quickly heated to boiling, so that the liquid can be sprayed into the emulsification chamber 11a through the jet hole 111a.

[0121] In one embodiment, please refer to Figures 3 to 5The lower surface of the bottom shell 111 is in a convex arc shape protruding upward or a concave arc shape protruding downward, and the jet hole 111a runs through the upper surface and the lower surface of the bottom shell 111. Specifically, the thickness of each position of the bottom shell 111 is equal. With such a design, the boiling energy can be gathered and then ejected through the jet hole 111a, achieving a better emulsification effect.

[0122] For some examples, see Figure 3 The lower surface of the bottom shell 111 is in an upwardly convex arc shape, and the center point of the bottom shell 111 is at the greatest distance from the bottom surface of the cooking cavity 2a. This can increase the volume below the bottom shell 111, and the space below the middle area of ​​the bottom shell 111 is the largest. Moreover, since the heat in the middle area is greater, more steam energy can be gathered to enhance the emulsification effect.

[0123] For some examples, see Figure 4 and Figure 5 The lower surface of the bottom shell 111 is in a concave arc shape convex downward, and the center point of the bottom shell 111 is at the minimum distance from the bottom surface of the cooking cavity 2a. This can increase the volume of the emulsification cavity 11a, evenly disperse the boiling steam and liquid in the emulsification cavity 11a, and enhance the boiling of the entire liquid surface.

[0124] In one embodiment, please refer to Figure 5 The ring shell 112 is formed with a spray hole 112a, and the spray hole 112a is connected to the emulsification chamber 11a. Exemplarily, the spray hole 112a is connected to the external space, that is, the interval space 2aa. The fluid medium in the interval space 2aa can enter the emulsification chamber 11a through the spray hole 112a to impact the fluid medium in the emulsification chamber 11a, thereby intensifying the disturbance of the fluid medium, thereby strengthening the flow mixing of the fluid medium and enhancing the emulsification effect.

[0125] The number of the injection hole 112a may be one or more.

[0126] In one embodiment, please refer to Figure 5 , the highest liquid level G in the emulsification chamber 11a is lower than the injection hole 112a. This prevents the fluid medium in the emulsification chamber 11a from blocking the injection hole 112a, causing the injection hole 112a to be unable to spray the fluid medium.

[0127] It should be noted that the maximum liquid level G refers to the maximum liquid level height of the fluid medium in the emulsification chamber 11a before heating.

[0128] In one embodiment, the equivalent diameter of the injection hole 112a is between 0.1 mm and 10 mm. Preferably, the equivalent diameter of the injection hole 112a is between 2 mm and 5 mm. Exemplarily, the equivalent diameter of the injection hole 112a is 0.1 mm, 0.2 mm, 1 mm, 1.5 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm, etc. In this way, the injection hole 112a is convenient for spraying fluid.

[0129] The equivalent diameter refers to four times the ratio of the flow cross-sectional area to the circumference. If the flow cross-sectional shape of the injection hole 112a is circular, the equivalent diameter is the diameter of the circular injection hole 112a.

[0130] In one embodiment, please refer to Figure 6 , the line between the center point of the horizontal plane projection of the jet hole 111a and the center point of the horizontal plane projection of the bottom shell 111 is the first line L1, the line between the center point of the horizontal plane projection of the injection hole 112a and the center point of the horizontal plane projection of the bottom shell 111 is the second line L2, and the angle α between the first line L1 and the second line L2 is greater than zero. In other words, the first line L1 and the second line L2 do not overlap. In this way, the jet hole 111a and the injection hole 112a are angularly displaced, so that the fluid ejected by the jet hole 111a and the fluid ejected by the injection hole 112a are staggered, which plays a role in disturbing the fluid medium and promoting the tumbling of the fluid medium.

[0131] In one embodiment, the angle between the adjacent first connecting line L1 and the adjacent second connecting line L2 is less than 90°. In this way, there is a suitable distance between the adjacent jet holes 111a and the injection holes 112a, and the disturbance effect is better.

[0132] In one embodiment, please refer to Figure 7 The emulsifying device 1 includes a filter housing 12, which is removably placed on the annular housing 112. The filter housing 12 has a cooking chamber 12a and a flow hole 12b, and the flow hole 12b connects the cooking chamber 12a and the emulsifying chamber 11a. On the one hand, the cooking chamber 12a can be used to place food, and the steam from the emulsifying chamber 11a can cook the food. On the other hand, during the heating and boiling process of the fluid medium in the emulsifying chamber 11a, the liquid level can rise into the cooking chamber 12a, and during the floating process of the liquid level, the foam can be retained on the wall surface of the cooking chamber 12a, or the filter housing 12 can be taken out, and the foam carried by the fluid medium will be retained on the wall surface of the cooking chamber 12a, thereby playing a role in separating the foam.

[0133] In one embodiment, please refer to Figure 7, the highest liquid level G in the emulsification chamber 11a can be lower than the filter housing 12. Exemplarily, the distance X between the lower surface of the filter housing 12 and the highest liquid level G is greater than 0 mm and not greater than 30 mm. In this way, the fluid medium in the emulsification chamber 11a is prevented from continuously soaking the food in the cooking chamber 12a.

[0134] In one embodiment, please refer to Figure 8 The emulsifying device 1 includes a handle 13, which is connected to the annular shell 112, and the height of the handle 13 is not higher than the height of the annular shell 112. The handle 13 is used for hand-holding. The handle 13 is convenient for the user to hold or place the emulsifying device 1, so as to complete the actions of blanching, draining, or taking out for washing. The height of the handle 13 is not higher than the height of the annular shell 112, which can prevent the handle 13 from increasing the overall height of the emulsifying device 1.

[0135] The number of handles 13 is not limited. For example, in one embodiment, please refer to Figure 8 The number of the handles 13 is two, and the two handles 13 are arranged opposite to each other in the radial direction. In this way, it is convenient for the two hands of the user to hold the two handles 13 respectively.

[0136] In one embodiment, please refer to Figures 14 to 18 At least one of the bottom shell 111, the annular shell 112, and the connection between the bottom shell 111 and the annular shell 112 is formed with a reflux hole 11b, which connects the emulsification chamber 11a and the external space, and is located radially outside the jet hole 111a. The reflux hole 11b is used to allow the fluid medium to flow back to the bottom of the jet hole 111a. Specifically, the reflux hole 11b is located at the bottom of the annular shell 112, that is, the height of the reflux hole 11b is lower than the height of the jet hole 112a.

[0137] In this embodiment, during the cooking process, continuous heating causes the boiling soup to be ejected through the jet hole 111a. After the boiling soup is ejected from the jet hole 111a, since the speed of gas generation is greater than the speed of soup ejection, an air layer will be briefly formed below the jet hole 111a, causing the liquid level in the emulsification chamber 11a to rise. The heating power can be changed, for example, heating can be stopped, so that the fluid medium can flow back to the space below the jet hole 111a through the reflux hole 11b and the jet hole 111a. In other words, the reflux hole 11b facilitates the soup that enters the emulsification chamber 11a when boiling to quickly flow back to the separation space 2aa after heating is stopped, thereby shortening the cooking time.

[0138] Exemplarily, in some embodiments, the bottom shell 111, the annular shell 112, or the connection between the bottom shell 111 and the annular shell 112 is formed with a reflux hole 11b. In other embodiments, the bottom shell 111 and the annular shell 112 are both formed with a reflux hole 11b. In still other embodiments, the bottom shell 111 and the connection between the bottom shell 111 and the annular shell 112 are both formed with a reflux hole 11b. In still other embodiments, the bottom shell 111, the annular shell 112, and the connection between the bottom shell 111 and the annular shell 112 are all formed with a reflux hole 11b.

[0139] In one embodiment, please refer to Fig.16 , the equivalent diameter D2 of the reflux hole 11b is between 0.1mm and 10mm. Preferably, the equivalent diameter D2 of the reflux hole 11b is between 2mm and 5mm. Exemplarily, the equivalent diameter D2 of the reflux hole 11b is 0.1mm, 0.2mm, 1mm, 1.5mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm or 10mm, etc. This facilitates the fluid medium in the emulsification chamber 11a to flow back to the separation space 2aa.

[0140] In one embodiment, the flow cross-sections at various positions of the return holes 11b are equal, the flow cross-sections at various positions of the jet holes 111a are equal, the flow cross-section area of ​​a single jet hole 111a is smaller than the flow cross-section area of ​​a single return hole 11b, and the total flow cross-section area of ​​all return holes 11b is smaller than the total flow cross-section area of ​​all jet holes 111a. In this way, the flow cross-section area of ​​a single jet hole 111a is smaller than the flow cross-section area of ​​a single return hole 11b, so that a jet is formed at the jet hole 111a, and the total flow cross-section area of ​​all return holes 11b is smaller than the total flow cross-section area of ​​all jet holes 111a, the number of return holes 11b is small, and the number of jet holes 111a is large, so that more jets are generated.

[0141] For some examples, see Figure 15 to Figure 16 The lower surface of the bottom shell 111 is in an upwardly convex arc shape, and the reflux hole 11b is arranged at the lowest part of the bottom shell 111 or at the connection between the bottom shell 111 and the annular shell 112. In the process of lifting the emulsifying device 1, the fluid medium in the emulsifying chamber 11a will flow along the bottom surface of the emulsifying chamber 11a to the position where the reflux hole 11b is located, accelerating the drainage so as to complete the drainage action as soon as possible.

[0142] In one embodiment, please refer to Figure 23 to Figure 26 The emulsifying shell 11 includes a support member 14 disposed at a lower portion of the emulsifying shell 11, and the support member 14 is used to support the emulsifying shell 11. For example, the support member 14 contacts the bottom surface of the cooking cavity 2a to support the emulsifying shell 11.

[0143] It should be noted that the lower portion of the emulsification shell 11 refers to a portion of the emulsification shell 11 located below the median line extending in the horizontal direction of the emulsification shell 11 .

[0144] For example, in some embodiments, the annular shell 112 , the bottom shell 111 and the support member 14 may be an integrally formed structure.

[0145] In one embodiment, please refer to Fig.23 The support member 14 includes a plurality of support blocks 141, and the plurality of support blocks 141 are spaced apart on the lower surface of the bottom shell 111. The plurality of support blocks 141 spaced apart can reduce interference with the fluid medium.

[0146] The specific shape of the support block 141 includes but is not limited to a support column or a convex hull, etc.

[0147] In one embodiment, please refer to Figure 24 to Figure 26 The support member 14 is an annular structure surrounding the outer periphery of the bottom shell 111. The jet hole 111a is located on the radial inner side of the support member 14 of the annular structure. On the one hand, the support member 14 of the annular structure has a good function of supporting the emulsifying device 1. On the other hand, the support member 14 of the annular structure can also enhance the effect of gathering steam, enhancing the jet effect and / or boiling effect.

[0148] In one embodiment, the support member 14 is formed with a notch, and the notch radially penetrates the support member 14. In other words, the notch connects the spaces on both sides of the support member 14 in the radial direction. In this way, the fluid medium in the space below the bottom shell 111 can flow through the notch to between the annular shell 112 and the circumferential surface of the cooking cavity 2a.

[0149] In one embodiment, please refer to Fig.12 , the equivalent diameter D1 of the jet hole 111a is not greater than 10 mm. In this way, it is convenient for the jet hole 111a to eject the jet under the action of the fluid medium and steam.

[0150] In some embodiments, the equivalent diameter D1 of the jet hole 111a is between 0.1 mm and 10 mm. Preferably, the equivalent diameter D1 of the jet hole 111a is between 2 mm and 5 mm. Exemplarily, the equivalent diameter D1 of the jet hole 111a is 0.1 mm, 0.2 mm, 1 mm, 1.5 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm, etc. In this way, it is convenient for the jet hole 111a to spray and generate a jet, strengthen the collision between fat and / or protein, and take into account the flow rate of a single jet hole 111a, and to a certain extent ensure that the fluid medium can flow through the jet hole 111a in a large amount.

[0151] In some embodiments, the equivalent diameter D1 of the jet hole 111a is less than 100 μm. Exemplarily, the equivalent diameter D1 of the jet hole 111a is 50 μm, 99 μm, 95 μm or 50 μm, etc. Since fat types are divided into three particle sizes: less than 50 μm, 50 μm to 100 μm, and more than 100 μm, among which fat with a particle size of 100 μm and below is soluble in water, the equivalent diameter D1 of the jet hole 111a is less than 100 μm. After the oil dissolved in the food passes through the jet hole 111a, it is continuously collided into particles less than 100 μm. At the same time, the flow rate of the fluid medium is increased. Under the pressure difference condition, the flow rate of the fluid medium will be greatly increased, and the fat and protein in the soup will continuously collide and squeeze in the path, promoting protein to wrap fat or fat to wrap protein or water molecules.

[0152] For example, in some embodiments, there are multiple jet holes 111a, and the equivalent diameter D1 of at least one jet hole 111a is less than 100 μm. In some embodiments, the equivalent diameter of at least one position of a single jet hole 111a is less than 100 μm.

[0153] In one embodiment, please refer to Fig.10 , the length Z of the jet hole 111a is between 0.1mm and 100mm. Preferably, the length Z of the jet hole 111a is between 1mm and 50mm. Exemplarily, the length Z of the jet hole 111a is 0.1mm, 0.2mm, 1mm, 1.5mm, 5mm, 10mm, 15mm, 25mm, 50mm, 80mm, 85mm, 90mm or 100mm, etc. In this way, the length Z of the jet hole 111a is moderate, avoiding that the length Z of the jet hole 111a is too small and the time for accelerating the fluid medium is too short, and avoiding that the length Z of the jet hole 111a is too long, resulting in excessive increase in the thickness of the bottom shell 111 or affecting the flow of the fluid medium.

[0154] It should be noted that the length Z of the jet hole 111a refers to the length of the jet hole 111a in the extending direction, that is, the length of the path of the fluid medium flowing in the jet hole 111a. Taking the L-shaped jet hole 111a formed by two intersecting flow segments as an example, the length Z of the L-shaped jet hole 111a is the sum of the lengths of the two intersecting flow segments.

[0155] In one embodiment, the ratio of the length Z of the jet hole 111a to the equivalent diameter is greater than 1. Preferably, the ratio of the length Z of the jet hole 111a to the equivalent diameter is greater than 3. In this way, the fluid medium has a longer circulation time in the jet hole 111a, so that fat and protein can fully collide and squeeze in the jet hole 111a, and the emulsification effect is good.

[0156] In some embodiments, the area of ​​the minimum flow cross section of the jet hole 111a is greater than 1 square millimeter. For example, in one embodiment, the area of ​​the flow cross section of a single jet hole 111a changes along its length, and the area of ​​the minimum flow cross section of the jet hole 111a is greater than 1 mm2. 2 In another embodiment, the flow cross-section area at each position of a single jet hole 111a is equal, that is, the flow cross-section area of ​​a single jet hole 111a is constant along its length direction, and the flow cross-section area at each position of the jet hole 111a is 1mm 2 In this way, the flow rate of the fluid medium will be greatly improved, and the fat and protein in the soup will constantly collide and squeeze along the path, promoting the protein to wrap around the fat or the fat to wrap around the protein or water molecules.

[0157] In some embodiments, the distance between two adjacent jet holes 111a is greater than 2 mm. Such a design facilitates the manufacturing of the jet holes 111a, reduces the manufacturing cost, and enables the jets ejected from each jet hole 111a to be more divergent.

[0158] In some embodiments, the emulsification chamber 11a is used to place food, so as to prevent the food placed in the cooking chamber 2a from touching the bottom shell 111, and the fluid medium in the emulsification chamber 11a is mixed and blended under the effects of jet flow and boiling, so as to be better emulsified.

[0159] In some embodiments, the maximum dimension of the annular shell 112 along the vertical direction is between 30 mm and 100 mm. For example, the maximum dimension of the annular shell 112 along the vertical direction is 30 mm, 50 mm, 80 mm or 100 mm, etc. In this way, the emulsifying shell 11 can be adapted to various existing pot bodies 2.

[0160] In some embodiments, the ratio of the total area of ​​the flow cross-section of all the jet holes 111a to the total area of ​​the cavity surface of the emulsification cavity 11a is less than 2%. Exemplarily, the ratio of the total area of ​​the flow cross-section of the jet holes 111a to the total area of ​​the cavity surface of the emulsification cavity 11a is 0.5%, 0.7%, 1%, 1.5% or 2%, etc. In this way, the volume ratio of the jet generated by the jet hole 111a to the fluid medium in the emulsification cavity 11a is moderate, so that the fluid medium can be emulsified in a shorter time.

[0161] It should be understood that if all jet holes 111a are equal diameter holes. Equal diameter holes refer to the equal diameters of the jet holes 111a at all positions, then the total flow cross-section area of ​​all jet holes 111a is the sum of the areas of any flow cross-section of all jet holes 111a. If at least some of the jet holes 111a are variable diameter holes. Variable diameter holes refer to the unequal diameters of at least two positions of the jet holes 111a, then the total flow cross-section area of ​​all jet holes 111a is the sum of the areas of the maximum flow cross-sections of all jet holes 111a.

[0162] In some embodiments, the ratio of the length Z of a single jet hole 111a to its maximum diameter is not greater than 200. Thus, the length Z of a single jet hole 111a and the size of the flow cross section of the fluid medium are appropriate, and the flow time of the fluid medium in the jet hole 111a and the degree of collision and extrusion are adapted.

[0163] It should be noted that the maximum diameter of the jet hole 111a means: if the jet hole 111a is a constant diameter hole, the maximum diameter of the jet hole 111a is the diameter of any flow cross section. If the jet hole 111a is a variable diameter hole, the maximum diameter of the flow cross section of a single jet hole 111a is used.

[0164] In one embodiment, please refer to Figure 29 to Figure 31 The emulsifying device 1 includes an anti-blocking member 15, which is arranged on the lower surface of the bottom shell 111 and is arranged around the jet hole 111a. The anti-blocking member 15 and the bottom shell 111 define a flow cavity 15a, and the anti-blocking member 15 is formed with an anti-blocking hole 15b connected to the flow cavity 15a, and the jet hole 111a is connected to the flow cavity 15a. Since the food will inevitably produce broken bones or other fine solids, there is a risk that these fine particles will block the jet hole 111a. Therefore, the anti-blocking member 15 is used to block the fine solids and the jet hole 111a, and the anti-blocking hole 15b is used to circulate the fluid medium, so that the fluid medium enters the jet hole 111a through the anti-blocking hole 15b and the flow cavity 15a.

[0165] In some embodiments, the anti-blocking member 15 can be integrally formed with the emulsifying shell 11. In other embodiments, the anti-blocking member 15 is detachably connected to the emulsifying shell 11.

[0166] In one embodiment, please refer to Fig.19 and Fig. 20 The pot body 2 includes a retaining member 21 disposed on the circumferential surface of the cooking cavity 2a, and the emulsifying shell 11 is formed with a flange 1121 folded outward, and the flange 1121 is located above the retaining member 21 and abuts against the retaining member 21. Exemplarily, the annular shell 112 is formed with a flange 1121 folded outward. The flange 1121 and the retaining member 21 are used to support the emulsifying shell 11 on the retaining member 21, so that the emulsifying device 1 is stably placed in the cooking cavity 2a.

[0167] The specific shape of the locking member 21 is not limited. For example, in some embodiments, the locking member 21 can be a hemispherical structure or a polyhedral structure, etc. Fig.19 and Fig. 20 Taking the hemispherical structure of the retaining piece 21 as an example, the flat end surface of the hemispherical structure of the retaining piece 21 is in contact with the circumferential surface of the cooking cavity 2a, and the spherical surface of the hemispherical structure of the retaining piece 21 can face the outer peripheral surface of the annular shell 112, thereby reducing the risk of the retaining piece 21 scratching the annular shell 112 due to its possible edges and corners.

[0168] In one embodiment, the flange 1121 is a thermal expansion structure, and the flange 1121 can reversibly switch between increasing the volume when the temperature rises and reducing the volume when the temperature drops. That is, when the temperature rises, the flange 1121 expands and deforms to reduce the distance between the flange 1121 and the cooking cavity 2a, thereby reducing the pressure loss at the flange 1121. When the temperature drops, the size of the flange 1121 decreases, and when the temperature of the flange 1121 returns to normal temperature, the volume of the flange 1121 returns to the normal temperature state, making it convenient for users to take and put.

[0169] Exemplarily, the flange 1121 may be made of a material with a large thermal expansion coefficient. For example, the material of the flange 1121 may be a double-layer metal or a plastic with a large thermal expansion coefficient.

[0170] In one embodiment, please refer to Fig.19 and Fig. 20 The pot body 2 includes a limiting member 22 disposed on the circumferential surface of the cooking cavity 2a. The limiting member 22 is located above the positioning member 21 and forms a limiting groove with the positioning member 21. The flange 1121 can pass over the limiting member 22 to enter or escape from the limiting groove. Exemplarily, the flange 1121 can be deformed and / or the limiting member 22 can be deformed so that the flange 1121 can pass over the limiting member 22. For example, the emulsifying shell 11 is pressed downward, the flange 1121 is deformed and / or the limiting member 22 is deformed so that the flange 1121 passes over the limiting member 22 and enters the limiting groove, and the flange 1121 abuts against the positioning member 21, thereby achieving the installation of the emulsifying device 1. After installation, unless the emulsifying device 1 is subjected to a large upward pulling force, the flange 1121 is difficult to escape from the limiting groove, thereby achieving the limiting effect. When the emulsifying device 1 needs to be taken out, the emulsifying shell 11 can be pulled upward, and the flange 1121 and / or the stopper 22 are deformed so that the flange 1121 passes over the stopper 22 and escapes from the stopper groove, thereby realizing the disassembly and assembly of the emulsifying device 1. In this way, the structure is simple, the operation is simple, and it is easy to realize.

[0171] The specific shape of the stopper 22 is not limited. For example, in some embodiments, the stopper 22 can be a hemispherical structure or a polyhedral structure. Fig.19 and Fig. 20The radius of the hemispherical limit member 22 can be smaller than the radius of the hemispherical stop member 21, the flat end surface of the hemispherical limit member 22 contacts the circumferential surface of the cooking cavity 2a, and the spherical surface of the hemispherical limit member 22 can face the outer circumferential surface of the ring shell 112, thereby reducing the risk of the limit member 22 scratching the ring shell 112 due to its possible edges and corners.

[0172] For some examples, see Fig.19 and Fig. 20 There are multiple clamping members 21, and the multiple clamping members 21 are arranged at intervals along the circumferential surface of the cooking cavity. The multiple clamping members 21 abut against the flange 1121 to support the emulsifying device 1 more stably.

[0173] For some examples, see Fig.19 and Fig. 20 The flange 1121 may surround the top of the annular shell 112 .

[0174] For some examples, see Fig.19 and Fig. 20 There are multiple limiting members 22 , and each positioning member 21 corresponds to one limiting member 22 .

[0175] In one embodiment, please refer to Figures 2 to 4 ,as well as Figure 7 , the height of the gap H is between 0.1 mm and 100 mm. Exemplarily, preferably, the height of the gap H is between 1 mm and 30 mm. Exemplarily, the height of the gap H is 0.1 mm, 0.2 mm, 1 mm, 1.5 mm, 5 mm, 10 mm, 15 mm, 25 mm, 30 mm, 50 mm, 80 mm, 85 mm, 90 mm or 100 mm, etc. In this way, the volume of the space between the lower surface of the annular shell 112 and the bottom surface of the cooking cavity 2a is moderate, so that the fluid medium in the space below the annular shell 112 enters the jet hole 111a and generates a jet.

[0176] In one embodiment, please refer to Fig.10 , the distance between the outer circumferential surface of the emulsifying shell 11 and the circumferential surface of the cooking cavity 2a is less than 2 mm. In some embodiments, the distance F between the outer circumferential surface of the annular shell 112 and the circumferential surface of the cooking cavity 2a is less than 2 mm. Exemplarily, the distance F between the outer circumferential surface of the annular shell 112 and the circumferential surface of the cooking cavity 2a is 1.9 mm, 1.5 mm, 1.0 mm or 0.5 mm, etc. In this way, the space between the outer circumferential surface of the annular shell 112 and the circumferential surface of the cooking cavity 2a is small, so that a pressure difference is formed between the inner and outer sides of the annular shell 112, so that the fluid medium in the space between the outer circumferential surface of the annular shell 112 and the circumferential surface of the cooking cavity 2a is sprayed into the emulsifying cavity 11a through the spray hole 112a.

[0177] In one embodiment, please refer to Fig.29 The cooking device includes a seal 3, which surrounds the top of the emulsifying shell 11, and abuts against the circumferential surface of the cooking cavity 2a to seal the gap between the circumferential surface of the cooking cavity 2a and the top of the emulsifying shell 11. Exemplarily, the seal 3 surrounds the top of the annular shell 112, and abuts against the circumferential surface of the cooking cavity 2a to seal the gap between the circumferential surface of the cooking cavity 2a and the top of the annular shell 112. The seal 3 prevents gas or fluid medium from escaping from the gap between the circumferential surface of the cooking cavity 2a and the top of the annular shell 112, so that there is a greater pressure difference between the separation space 2aa and the emulsifying chamber 11a, which facilitates the fluid medium to be ejected through the jet hole 111a.

[0178] For example, in one embodiment, please refer to Fig.29 , the seal 3 is coated on the outer edge of the flange 1121. In this way, the seal 3 can also prevent the flange 1121 from scratching the circumferential surface of the cooking cavity 2a, thereby avoiding scratches.

[0179] There is no limitation on the heating method of the cooking utensil. For example, the heating method of the cooking utensil includes but is not limited to resistance heating, far infrared heating, electromagnetic heating or flame heating, etc.

[0180] The specific type of cooking utensils is not limited. For example, cooking utensils include but are not limited to rice cookers, pressure cookers, stew pots, induction cookers or health pots, etc.

[0181] The material of the emulsifying shell 11 includes but is not limited to metal material and / or high temperature resistant plastic and the like.

[0182] In one embodiment, please refer to Figure 27 to Figure 29 The cooking cavity 2a can also be used to place food.

[0183] In one embodiment, please refer to Fig.24 The lower surface of the bottom shell 111 is in a convex arc shape protruding upward, and the support member 14 is in a ring structure surrounding the outer periphery of the bottom shell 111. The support member 14 can enhance the effect of steam gathering, so that the steam moves violently and sprays out from the jet hole 111a.

[0184] In one embodiment, please refer to Fig.25 The lower surface of the bottom shell 111 is in a concave arc shape convex downward, and the support member 14 is in an annular structure surrounding the outer periphery of the bottom shell 111. A plurality of injection holes 112a are arranged at intervals along the circumference of the annular shell 112 and are located on the radial inner side of the support member 14. The support member 14 can gather steam in the space below the bottom shell 111. The generated steam does not have time to be discharged from the jet holes 111a. The steam has a low density and moves to the surroundings, and then it will be ejected from the injection holes 112a on the annular shell 112, which plays a role in strengthening the injection.

[0185] In another embodiment, see Fig.26 The lower surface of the bottom shell 111 is in a concave arc shape convex downward, and the support member 14 is in an annular structure surrounding the outer circumference of the bottom shell 111. A plurality of injection holes 112a are arranged at intervals along the circumference of the ring shell 112 and are located on the radial outer side of the support member 14. The support member 14 can gather steam in the space below the bottom shell 111. The generated steam does not have time to be discharged from the jet holes 111a. The steam has a low density and will move around, accumulate around the support member 14, and move through the notch on the support member 14 to between the outer circumferential surface of the ring shell 112 and the circumferential surface of the cooking cavity 2a, thereby squeezing the soup to be ejected from the injection holes 112a, forming a liquid injection effect.
