Figure 1 is a simple module schematic diagram of a cooking device according to some embodiments of this specification. Figure 1 illustrates an embodiment of a cooking device 100. The cooking device 100 may be any device that performs cooking operations according to a preset cooking program and controllably adjusts cooking parameters to cook ingredients. As shown in FIG. 1 , the cooking device 100 may include a liquid storage tank 10 and a host machine 200 . The host 200 may include a temperature adjustment component 30 , a control component 50 and a power supply component 60 . The liquid storage tank 10 can be used to contain liquid for heating food. By way of example, the liquid may include purified water. The temperature adjustment assembly 30 may be used to adjust the temperature of the liquid in the liquid storage tank 10 . The control component 50 can communicate/connect with one or more of the aforementioned components, and is used to control one or more components to work. For example, the control component 50 can control the temperature adjustment component 30 to heat the liquid in the liquid storage tank. Power supply assembly 60 may be used to power various components.

In some embodiments, power component 60 may include a power management system, one or more power sources (eg, batteries or alternating current (AC)), a charging system, power failure detection circuitry, a power converter or inverter, a power status indicator (For example, light emitting diodes (LEDs), but may also include any other component associated with the generation, management, and distribution of electrical energy.

In some embodiments, the liquid storage tank 10 and the host 200 may be fixed through a connecting structure. Exemplary connection structures may include positioning structures and docking structures. The positioning structure can be used to position positioning posts and positioning holes to facilitate docking of the docking structure.

It should be understood that the cooking device 100 is only one example and may have more or fewer components than shown, or have different component configurations. The various components described in accompanying Figure 1 may be implemented using hardware, software, or a combination of hardware and software, including one or more signal processing and/or application specific integrated circuits.

In some embodiments, the cooking device 100 may be a sous vide machine, which is a cooking device that uses a sous vide cooking method. Vacuum the vacuum bag containing the ingredients using a vacuum machine. Then the vacuum bag containing the ingredients is placed into the container as a whole, and liquid with a certain temperature is used for low-temperature cooking. The low temperature mentioned here may refer to a temperature lower than the boiling point of the liquid. For example, at standard atmospheric pressure, the boiling point of water is 100 degrees. Therefore, water below 100 degrees Celsius (for example, hot water of 60 degrees Celsius) can be used to heat food ingredients.

In some embodiments, the reservoir 10 may have an open end for placing ingredients therein. In some embodiments, the liquid storage tank 10 may include a top cover, and before cooking the food, the food and the liquid used to heat the food may be put into the liquid storage tank 10 from the open end. During the process of cooking food, the top cover can be placed on the open end to reduce heat loss in the liquid storage tank 10 .

In some embodiments, the shape of the liquid storage tank 10 may include a cylindrical shape (eg, a cylinder), a prism shape (eg, a cuboid, a cube, etc.), a cone shape (eg, a cone, a pyramid, etc.), or any other feasible shape. .

In some embodiments, the temperature regulation assembly 30 may include a heating element, such as a thermistor type heating element. The temperature of the heating element can be adjusted as needed, and the temperature of the liquid in the liquid storage tank 10 is controlled by placing the heating element in the liquid in the liquid storage tank 10 . By way of example, the heating element may include a heating rod. The heating rod may have a certain temperature, and the liquid in the liquid storage tank 10 is heated by extending the heating rod into the liquid in the liquid storage tank 10 . In another example, the heating element may include a heating plate disposed at the bottom of the liquid storage tank 10 .

In some embodiments, the control component 50 in the cooking device 100 can issue an instruction to start heating or start cooking. After the temperature adjustment component 30 is run, the temperature of the heating element can be adjusted. By setting the operating parameters of the temperature adjustment component 30 (for example, the temperature of the heating element, etc.), the temperature of the liquid in the liquid storage tank 10 can be adjusted.

In some embodiments, temperature regulation assembly 30 may include a temperature sensor. The temperature sensor can be used to detect the real-time temperature of the liquid in the liquid storage tank 10 . The temperature sensor can simultaneously convert the temperature value into a detectable electrical signal and send it to the control component 50. The control component 50 can drive the temperature adjustment component 30 to control the temperature of the heating element according to the temperature value to control the liquid in the liquid storage tank 10. temperature purpose.

In some embodiments, due to the large internal volume of the liquid storage tank 10, the heating element has different heating effects on liquids that are farther away and liquids that are further away. Liquids that are closer to the heating element (heat source) heat up quickly and have a higher temperature. Liquids that are farther away from the heating element (heat source) heat up slowly and have a lower temperature. This will result in temperature differences between liquids at different locations in the liquid storage tank 10. For example, in a heating rod heating method, the temperature rise rate of the liquid closer to the heating rod is greater than the temperature rise rate of the liquid farther away from the heating rod. When food is immersed in liquid, the uneven temperature of the liquid will cause uneven heating of different parts of the food, resulting in differences in the doneness and taste of different parts of the food, affecting the user's eating experience to a certain extent.

In some embodiments, the heating element may include a heating rod, the bottom of which is provided with rotatable blades. When the heating rod is working, the blades can rotate to stir the surrounding liquid, thereby realizing heat exchange between the liquids and making the temperature of the liquids at different locations in the liquid storage tank 10 more uniform. In some embodiments, the heating rod is usually fixed at a certain position in the liquid storage tank 10, and the position of the blade is also fixed accordingly. This may result in less volume of liquid being stirred by the blades. In addition, the blades stir the liquid farther away to a lesser extent, resulting in less efficient heat exchange between the liquids. Moreover, the blades stir the liquid in different areas to different degrees, which may lead to large differences in the liquid flow rates in different areas (for example, the blades stir the liquid farther away to a smaller degree, resulting in a slower flow rate of the liquid. The blades stir the liquid farther away). The degree of agitation of the nearby liquid is large, resulting in a faster flow rate of the liquid), thereby affecting the uniformity and stability of the liquid temperature at different positions in the liquid storage tank 10 . The above reasons may eventually lead to uneven liquid temperatures at different locations in the liquid storage tank 10 . The uniform temperature of the liquid mentioned in this specification may mean that the temperatures at different locations in the liquid are the same or substantially the same at the same time. Stable liquid temperature may mean that the temperature at different locations in the liquid is the same or substantially the same within a certain period of time.

In some embodiments, the culture device 100 may further include a liquid inlet and outlet assembly 20 . The liquid in the liquid storage tank 10 can enter the pipeline on the side of the host 200 through the liquid inlet and outlet assembly 20 . The liquid in the pipeline on the side of the host 200 can also enter the liquid storage tank 10 through the liquid inlet and outlet assembly 20 . Finally, a liquid circulation is formed between the main unit 200 and the liquid storage tank 10 . In some embodiments, after the liquid inlet and outlet assembly 20 is provided, the temperature adjustment assembly located outside the liquid storage tank 10 can be used to heat the liquid. For example, the temperature adjustment assembly may include a heating pipe, and the heating pipe may be disposed on a pipeline for liquid circulation outside the liquid storage tank 10 to heat the liquid in the pipeline. In some embodiments, through the arrangement of the water inlet and outlet assembly 20, the flow path of the liquid in the liquid storage tank 10 can be adjusted, making the liquid circulation path more and more complex. More and more complex liquid circulation paths can be more conducive to heat exchange between liquids, thereby promoting the liquid temperature in the liquid storage tank 10 to become consistent.

This manual provides a liquid storage tank. The liquid storage tank can transport liquid and outflow liquid respectively through the liquid inlet and liquid outlet provided on its inner wall. For example, the liquid inlet and the liquid outlet can be provided on the side wall of the liquid storage tank (as shown in Figures 5 and 11), so that liquid can flow into or out of the liquid storage tank from the side wall of the liquid storage tank. In some application scenarios, vacuum bags can usually be placed in the liquid storage tank along the length or width of the liquid storage tank. By adjusting the placement direction of the vacuum bag, the liquid can flow along the surfaces of both sides of the vacuum bag after entering the liquid storage tank from the liquid inlet, thereby causing liquid movement in more areas and fully realizing direct heat exchange of the liquid. In addition, in one or more embodiments of this specification, the size, structure, and location of the liquid inlet, as well as the positional relationship between the liquid inlet and the liquid outlet, can also be improved, so that the liquid inlet can be obtained from the liquid inlet. The liquid sprayed into the liquid storage tank through the mouth can stir the liquid in more areas, thereby expanding the stirring range of the liquid in the liquid storage tank, improving the uniformity and stability of the liquid temperature at various locations in the liquid storage tank, so that at low temperatures During the cooking process, different positions of the ingredients can be heated evenly, so that the doneness of the ingredients in different positions tends to be consistent.

As shown in Figures 2, 5 and 6, in some embodiments, the liquid storage tank 100 may include a liquid inlet 110 and a liquid outlet 120, and the size of the liquid inlet 110 along the length direction of the liquid storage tank 10 may be It is larger than the size of the liquid inlet 110 along the height direction of the liquid storage tank 10 . The liquid inlet 110 may refer to an opening through which liquid enters from the outside of the liquid storage tank 10 to the inside of the liquid storage tank 10 . The liquid outlet 120 may refer to an opening through which liquid flows out from the inside of the liquid storage tank 10 . The length direction of the liquid storage tank 10 may refer to the length direction of the longer side wall of the liquid storage tank 10 or the length direction of the shorter side wall of the liquid storage tank 10 . The specific direction of the length direction of the liquid storage tank 10 may be related to the position where the liquid inlet 110 is provided. For example, when the liquid inlet 110 is disposed on a shorter side wall of the liquid storage tank 10 (ie, the short side of the liquid storage tank 10 ), the length direction of the liquid storage tank 10 may refer to the length of the liquid storage tank 10 . The length of the shorter sidewall. For example, when the liquid inlet 110 is disposed on a longer side wall of the liquid storage tank 10 (ie, the long side of the liquid storage tank 10), the length direction of the liquid storage tank 10 may refer to the length of the liquid storage tank 10. The length of the longer side wall.

In order to facilitate understanding of the length direction of the liquid storage tank 10, this description takes the liquid storage tank 10 shown in Figures 5 and 11 as an example. In some embodiments, the liquid storage tank 10 may include a bottom wall 101 and interconnected Four side walls. The four side walls may include two first side walls 102 and two second side walls 103 . The length of the first side wall 102 (ie, the long side of the liquid storage tank 10) is greater than the length of the second side wall 103 (ie, the wide side of the liquid storage tank 10). The connection surface between the first side wall 102 and the second side wall 103 may be an arc surface, so that the internal contour shape of the liquid storage tank 10 is quasi-cuboid. In this embodiment, when the liquid inlet 110 is disposed on the first side wall 102 of the liquid storage tank 10, the length direction of the liquid storage tank 10 may be the length direction of the first side wall 102, as shown in FIG. 5 and FIG. Indicated by arrow X in 11. When the liquid inlet 110 is provided on the second side wall 103 of the liquid storage tank 10, it may also be in the length direction of the second side wall 103, as shown by the arrow Y in Figures 5 and 11. As shown in FIGS. 5 and 11 , since the liquid inlet 110 is provided on the first side wall 102 of the liquid storage tank 10 , the length direction of the liquid storage tank 10 may refer to the length direction of the first side wall 102 , as shown in FIG. 5 and arrow X in Figure 11. The width direction of the liquid storage tank 10 may refer to the length direction of the second side wall 103, as shown by the arrow Y in FIG. 5 and FIG. 11 . The height direction of the liquid storage tank 10 may refer to the height direction of the first side wall 102 and the second side wall 103. As shown by the arrow H in Figures 5 and 11, the height direction of the liquid storage tank 10 is perpendicular to the length direction and width direction.

In this embodiment, liquid with a specific temperature can be transported from the liquid inlet 110 of the liquid storage tank 10 to the inside of the liquid storage tank 10 to stir the original liquid in the liquid storage tank 10 . The agitation of the liquid can promote the mixing of the liquid at various locations in the liquid storage tank 10 , thereby promoting the liquid temperature at various locations in the liquid storage tank 10 to become consistent.

As shown in FIG. 13 , in this embodiment, since the size of the liquid inlet of the liquid storage tank 10 along the length direction of the liquid storage tank 10 is greater than the size in the height direction, the cross-section of the opening of the liquid inlet 110 is flat. shape. When the liquid is sprayed from the liquid inlet 110 into the liquid storage tank 10 , it will flow to the front and both sides of the liquid inlet 110 , thereby forming an inverted triangle, sector or trapezoidal shape. The shape mentioned here may refer to the shape of the liquid when viewed from the height direction of the liquid. The front of the liquid inlet 110 may refer to the side where the opening of the liquid inlet 110 points toward the inside of the liquid storage tank 10 along the width direction of the liquid storage tank 10 , as shown by arrow P in FIG. 13 . The two sides of the liquid inlet 110 may refer to the two sides of the opening of the liquid inlet 110 along the length direction of the liquid storage tank 10 . When a liquid with a specific shape (for example, fan-shaped) hits the side wall of the liquid storage tank 10 (for example, the liquid inlet is provided on the side wall of the liquid storage tank 10), the fan-shaped liquid can hit the side wall opposite to the liquid inlet 110. (side wall), the fan-shaped liquid will form several shunts. Several shunts flow upward, downward and backward. The upward and downward flow mentioned here may refer to the upward and downward flow of liquid along the height direction of the liquid storage tank 10 . The backward flow may mean that the liquid flows along the width direction of the liquid storage tank 10 away from the side wall (ie, the side wall where the liquid hits). Finally, several partial flows can flow out of the liquid storage tank 10 through the liquid outlet 120 . In some cases, if the liquid inlet 110 is disposed on the side wall of the liquid storage tank 10, when the fan-shaped liquid moves to the side wall opposite to the liquid inlet 110, the liquid will form an inclination angle with the side wall. The inclination angle allows the liquid to continue flowing along the side wall toward the edge of the side wall after hitting the side wall of the liquid storage tank 10 , which allows the liquid to continue to stir the original liquid in the liquid storage tank 10 . In other cases, the liquid may form a circular flow during the process from the liquid inlet into the liquid storage tank 10 to the liquid outlet, stirring the liquid in the liquid storage tank 10 . Due to the larger range of the circulation, more of the original liquid in the liquid storage tank 10 can be stirred, which has a good effect on improving the uniformity of the liquid in the liquid storage tank, thereby allowing the food in the liquid storage tank 10 to be heated evenly. In the end, the doneness of different parts of the ingredients tends to be consistent and the taste is better.

The outer layer and the inner layer may be connected to each other, and air may be insulated between the outer layer and the inner layer to reduce heat loss of the liquid storage tank 10 . In some embodiments, the length dimension of the outer layer of the liquid storage tank 10 may be 343.86 mm. The width dimension of the outer layer of the liquid storage tank 10 may be 255.89mm. The height dimension of the outer layer of the liquid storage tank 50 may be 241.89 mm. In some embodiments, the difference between the dimensions of the outer layer and the inner layer of the liquid storage tank 10 may be greater than or equal to 5 mm. For example, the length, width, and height of the inner layer of the liquid storage tank 10 are respectively 5 mm smaller than the size of the outer layer of the liquid storage tank 10 .

In some embodiments, the size of the reservoir 10 may be determined based on the size of the vacuum bag. In some embodiments, two types of vacuum bags are used. One large vacuum bag can be placed along the long side of the liquid storage tank 10 , and four small vacuum bags can be placed along the wide side of the liquid storage tank 10 . The size of the large vacuum bag can be 300mm*215mm (length of the long side*length of the short side). Small vacuum bag size can be 210mm*215mm.

In some embodiments, the ratio of the area of the small vacuum bag to the area of the first side wall 102 may range from 0.7 to 1. In some embodiments, the ratio of the area of the small vacuum bag to the area of the first side wall 102 may range from 0.7 to 0.8. In some embodiments, the ratio of the area of the small vacuum bag to the area of the first side wall 102 may be 0.73. In some embodiments, the ratio of the area of the large vacuum bag to the area of the second side wall 103 may range from 0.7 to 1. In some embodiments, the ratio of the area of the large vacuum bag to the area of the second side wall 103 may range from 0.7 to 0.8. In some embodiments, the ratio of the area of the large vacuum bag to the area of the second side wall 103 may be 0.77. If the size difference between the vacuum bag and the liquid storage tank 50 is too small, the gap between the vacuum bag and the inner wall of the liquid storage tank 50 will be small, making it inconvenient for the liquid to flow around the vacuum bag, thereby causing the gap around the vacuum bag to The liquid temperature is uneven and the food in the vacuum bag cannot be heated evenly. If the ratio is too small, space will be wasted. In some embodiments, the volume of the liquid storage tank 10 may be greater than or equal to 12L.

In some embodiments, the ratio of the size of the liquid inlet 110 along the length direction of the liquid storage tank 10 to the length of the liquid storage tank 10 may range from 1/20 to 1/10. In some embodiments, the ratio of the size of the liquid inlet 110 along the length direction of the liquid storage tank 10 to the length of the liquid storage tank 10 may range from 1/18 to 1/15. In some embodiments, the ratio of the size of the liquid inlet 110 along the length direction of the liquid storage tank 10 to the length of the liquid storage tank 10 may range from 1/16 to 1/15.

It should be noted that the value range of the size of one or more structures involved in the embodiments of this specification can be adaptively adjusted according to the volume of the liquid storage tank 10 . For example, the size of the liquid inlet 110 along the length direction of the liquid storage tank 10 may be positively correlated with the length of the liquid storage tank 10 . In another example, the size of the liquid outlet 120 along the height direction of the liquid storage tank 10 may be positively correlated with the height of the liquid storage tank 10 .

In some embodiments, the ratio of the size of the liquid inlet 110 along the length direction of the liquid storage tank 10 and the size along the height direction of the liquid storage tank 10 can be controlled so that the opening cross section of the liquid inlet 110 is flatter to increase the liquid content. Circulation stirring effect.

In some embodiments, the ratio of the size of the liquid inlet 110 along the length direction of the liquid storage tank 10 to the size of the liquid inlet 110 along the height direction of the liquid storage tank 10 may range from 1.1 to 7.5. In some embodiments, the ratio of the size of the liquid inlet 110 along the length direction of the liquid storage tank 10 to the size of the liquid inlet 110 along the height direction of the liquid storage tank 10 may range from 1.3 to 6. In some embodiments, the ratio of the size of the liquid inlet 110 along the length direction of the liquid storage tank 10 to the size of the liquid inlet 110 along the height direction of the liquid storage tank 10 may range from 1.5 to 4.5.

In some embodiments, the liquid inlet 110 and the liquid outlet 120 may be disposed on the side wall of the liquid storage tank 10 . For example, in the embodiment shown in FIG. 5 , a baffle 240 is provided on the side wall of the liquid storage tank 10 , and the liquid inlet 110 and the liquid outlet 120 can be provided on the baffle 240 . In another example, as shown in FIG. 11 , a mounting housing 130 is provided on the side wall of the liquid storage tank 10 , and the liquid inlet 110 and the liquid outlet 120 may be provided on the mounting housing 130 . In one or more embodiments of this specification, the baffle 240 and the mounting housing 130 may refer to the shell structure of the assembly including components such as a liquid inlet and a liquid outlet. This shell structure can be used to connect with the inner surface of the side wall of the liquid storage tank 10 . In some embodiments, the baffle 240 may be part of the liquid inlet and outlet assembly 20 in other embodiments of this specification.

In some embodiments, the baffle 240 and the mounting housing 130 may be part of the side wall of the liquid storage tank 10 . For example, in the embodiment shown in FIG. 5 , the baffle 240 may be a part of the first side wall 102 , and other components of the liquid inlet and outlet assembly 20 may be connected to the baffle 240 and then connected to the liquid storage tank 10 . In some embodiments, the baffle 240 and the mounting housing 130 may be integrally formed with the side wall of the liquid storage tank 10 . In other embodiments, the baffle 240 and the mounting housing 130 may be independent of the side walls of the liquid storage tank 10 . For example, the first side wall 102 of the liquid storage tank 10 may have a gap that is adapted to the baffle 240, and the baffle 240 may be embedded in the gap. For more details about the liquid inlet and outlet assembly 20, please refer to the relevant embodiments of FIGS. 8-10, and will not be described again here.

In some embodiments, the liquid inlet 110 may be disposed on a longer side wall of the liquid storage tank 10 . Exemplarily, in the embodiments shown in FIGS. 5 and 11 , the liquid inlet 110 is provided on the first side wall 102 of the liquid storage tank 10 through the baffle 240 and the mounting housing 130 respectively. In some cases, the liquid inlet 110 is disposed on a longer side wall of the liquid storage tank 10 , so the distance between the side wall where the liquid inlet 110 is located and the side wall opposite to the side wall where the liquid inlet 110 is located is shorter. (The distance between the two first side walls 102 may be approximately equal to the length of the second side wall 103). Therefore, the distance required for the liquid to flow through the liquid inlet 110 into the liquid storage tank 10 and hit the opposite side wall is shorter (that is, the liquid flow stroke is shorter), which facilitates the formation of liquid circulation.

In some embodiments, the liquid inlet 110 may be disposed at a middle position of the side wall of the liquid storage tank 10 along the length direction of the liquid storage tank 10 . For example, in the embodiment shown in FIG. 5 , the baffle 240 is embedded in the middle position of the first side wall 102 in the length direction. The liquid inlet 110 is disposed at an intermediate position of the baffle 240 along the length direction of the liquid storage tank 10 . Therefore, the liquid inlet is located at the middle position of the side wall of the liquid storage tank 10 along the length direction of the liquid storage tank 10 . For another example, in the embodiment shown in FIG. 11 , the mounting housing 130 is protrudingly disposed at a middle position in the length direction of the first side wall. The mounting housing 130 may include a housing first side wall 131 and a housing second side wall 132 . Both sides of the first side wall 131 of the housing are respectively connected to the second side wall 132 of the housing and the first side wall 102 of the liquid storage tank 10 . The second side wall 132 of the housing is located on the side of the first side wall 131 of the housing away from the first side wall 102 . The liquid inlet 110 may be provided on the second side wall 132 of the housing, and the liquid inlet 110 is located at an intermediate position of the second side wall 132 of the housing along the length direction of the liquid storage tank 10 . Therefore, the liquid inlet 110 is located at the middle position in the length direction of the liquid storage tank 10 . In some cases, when the liquid inlet 110 is disposed at the middle position of the side wall of the liquid storage tank 10 along the length direction of the liquid storage tank 10, after the liquid ejected from the liquid inlet 110 hits the opposite side wall, It is easier to form liquid shunts toward the left and right sides, thereby expanding the range of stirring of the liquid in the liquid storage tank 10 and improving the stirring efficiency.

In some embodiments, the liquid inlet 110 may be symmetrical along a centerline along the length direction of the liquid storage tank 10 . In some cases, when the liquid inlet 110 is symmetrical along the center line of the length direction of the liquid storage tank 10 , the liquid ejected from the liquid inlet 110 hits the opposite side wall to form a shunt of liquid on the left and right sides, which affects the other sides. The stirring effect of the liquid in the area is basically the same, making the overall temperature uniformity and stability of the liquid in the liquid storage tank 10 better.

As shown in FIG. 7 , in some embodiments, the liquid inlet 110 may include outwardly inclined sides. The outward direction mentioned here refers to the direction away from the central axis O of the liquid inlet 110 . In some embodiments, the distance between the end of the side of the liquid inlet 110 away from the inside of the liquid storage tank 10 and the central axis of the liquid inlet 110 is a first distance D1, and the side of the liquid inlet 110 is close to the inside of the liquid storage tank 10 The distance between one end of and the central axis of the liquid inlet 110 is the second distance D2. The outward tilt may mean that the first distance D1 is less than the second distance D2, so that the plane or curved surface of the side is located between the center of the liquid inlet 110 and The axes O intersect to form an included angle. The sides of the liquid inlet 110 are tilted outward at a certain angle, so that after the liquid enters the inside of the liquid storage tank 10 from the liquid inlet, it is easier to form a fan-shaped liquid. In some embodiments, the angle of the outward inclination of the side of the liquid inlet 110 may range from 0 to 90 degrees. In some embodiments, the angle of the outward inclination of the side of the liquid inlet 110 may range from 30 degrees to 60 degrees. In some embodiments, the outward inclination angle of the sides of the liquid inlet 110 may be 45 degrees.

For example, as shown in FIGS. 5 , 7 and 12 , the liquid inlet 110 may be provided on the longer first side wall 102 of the liquid storage tank 10 . The length direction of the first side 111 of the liquid inlet 110 may be parallel to the length direction of the first side wall 102 . The length direction of the second side 112 of the liquid inlet 110 may be parallel to the length direction of the second side wall 103 of the liquid storage tank 10 . The second side 112 of the liquid inlet 110 is inclined outward, and the second distance D2 between the end of the second side 112 close to the inside of the liquid storage tank 10 and the central axis O is greater than the distance D2 between the second side 112 and the end of the second side 112 away from the inside of the liquid storage tank 10 . The first distance D1 from one end to the central axis O is such that the plane where the surface of the second side 112 is located intersects the extension line of the central axis O with the point M, thereby forming an included angle α.

In other embodiments, both the first side 111 and the second side 112 of the liquid inlet 110 may be inclined outward. For example, based on the embodiments shown in FIG. 5 and FIG. 7 , the first side 111 of the liquid inlet 110 is also tilted outward, so that the liquid inlet 110 is shaped like a trumpet.

In some embodiments, whether the liquid can form a fan shape, an inverted triangle, or a trapezoid is related to the outward inclination angle α of the second side 112 of the liquid inlet 110 and the length dimension of the liquid storage tank 10 . In some embodiments, the outward inclination angle α of the second side 112 of the liquid inlet 110 may affect the effect of circulating flow agitation. For example, when the outward inclination angle α of the two second sides 112 is too large and the length of the liquid storage tank 10 is small, the liquid may form a backflow after hitting the second side wall 103 of the liquid storage tank 10 . The reverse flow may collide with the liquid ejected from the liquid inlet 110 , thereby weakening the stirring effect of the liquid on the original liquid in the liquid storage tank 10 .

In some embodiments, the opening shape of the liquid inlet 110 may include, but is not limited to, rectangular (eg, square, rectangular), quasi-rectangular (eg, racetrack-shaped), trapezoid, oval, etc. As shown in FIG. 6 , in some specific embodiments, the opening shape of the liquid inlet 110 may be a racetrack shape, that is, the connection angle between the first side 111 and the second side 112 is a rounded corner. In some embodiments, the opening shape of the liquid outlet 120 is the same or similar to the opening shape of the liquid inlet 110 , which will not be described again here.

In some embodiments, the height of the liquid outlet 120 may be lower than the lowest water level of the liquid storage tank 10 , and the liquid inlet 110 may be disposed below the liquid outlet 120 . The lowest water level line of the liquid storage tank 10 may refer to the lowest height of the liquid level in the liquid storage tank 10 when cooking food. As shown in FIGS. 11 and 12 , the installation housing 130 is engraved with a mark of the lowest water level (“MIN”) and a mark of the highest water level (“MAX”). The two liquid outlets 120 provided on the installation housing 130 are both located below the lowest water level. The highest water level of the liquid storage tank 10 may refer to the liquid level height when the liquid contained in the liquid storage tank 10 reaches the maximum allowable volume. In this embodiment, since the height of the liquid outlet 120 is lower than the lowest water level of the liquid storage tank 10, when the liquid inlet 110 is disposed below the liquid outlet 120, it can be ensured that the height of the liquid inlet 110 is also lower than The lowest water level of the liquid storage tank 10. In some cases, since the liquid outlet 120 and the liquid inlet 110 are both located below the lowest water level, the liquid in the liquid storage tank 10 can be stirred after the liquid is ejected from the liquid inlet 110, and the liquid can be ejected from the liquid outlet 110. 120 flows out, and enters the liquid storage tank 10 again through the liquid inlet 110, so as to form a liquid circulation.

In some embodiments, the effect of liquid circulation stirring is also related to the distance between the liquid inlet 110 and the bottom of the liquid storage tank 10 , which may be called the inlet distance for convenience of description. The distance between the liquid inlet 110 and the bottom of the liquid storage tank 10 mentioned here may refer to the distance between the liquid inlet 110 and the bottom wall 101 of the liquid storage tank 10 in the height direction of the liquid storage tank 10 . For example, the distance between the first side 111 of the liquid inlet 110 and the bottom wall 101 of the liquid storage tank 10 .

In some embodiments, the liquid inlet 110 may be disposed near the bottom of the liquid storage tank 10 . In some cases, when liquid is sprayed from the liquid inlet 110 into the inside of the liquid storage tank 10 , the liquid will spread around the liquid inlet 110 . If the liquid inlet 110 is close to the bottom of the liquid storage tank 10 , the bottom wall 101 of the liquid storage tank 10 can guide the liquid, so that the liquid moves along the bottom wall 101 of the liquid storage tank 10 toward the side wall opposite to the liquid inlet 110 Diffusion, thereby increasing the range of liquid agitation.

In some embodiments, the distance between the liquid inlet 110 and the bottom of the liquid storage tank 10 may range from 2 cm to 10 cm. In some embodiments, the distance between the liquid inlet 110 and the bottom of the liquid storage tank 10 may range from 2.5 cm to 8 cm. In some embodiments, the distance between the liquid inlet 110 and the bottom of the liquid storage tank 10 may range from 3 cm to 7 cm.

In some embodiments, the distance between the liquid inlet 110 and the bottom of the liquid storage tank 10 is the inlet distance, and the ratio of the inlet distance to the height of the highest water level of the liquid storage tank 10 ranges from 0.0001 to 1. In some embodiments, the ratio of the inlet distance to the height of the highest water level of the liquid storage tank 10 ranges from 0.05 to 0.5.

In some embodiments, the liquid inlet 110 and the liquid outlet 120 may be located on the same side wall of the liquid storage tank 10 . Exemplarily, in the embodiments shown in Figures 5 and 11, the first side wall 102 of the liquid storage tank 10 is provided with a baffle 240 and a mounting housing 130, respectively. The baffle 240 and the mounting housing 130 are respectively Both are provided with a liquid inlet 110 and a liquid outlet 120 . Therefore, in the embodiment shown in FIG. 5 and FIG. 11 , the liquid inlet 110 and the liquid outlet 120 are both disposed on the first side wall 102 of the liquid storage tank 10 . In some cases, the liquid sprayed from the liquid inlet 110 may collide with an opposite side wall of the liquid inlet 110 , and then form several liquid branches flowing in different directions (eg, upper left, upper right, etc.). Since the liquid inlet 110 and the liquid outlet 120 are disposed on the same side wall, under the suction of the liquid outlet 120, several partial flows will return to the side wall where the liquid inlet 110 is located along different paths, and finally converge at the outlet. 120 liquid ports. In the process of several partial flows returning to the liquid outlet 120, the several partial flows can stir the liquid in different areas, thereby causing more liquid to mix, further promoting the liquid temperature in the liquid storage tank 10 to become consistent.

In some embodiments, the liquid inlet 110 and the liquid outlet 120 may be disposed on different side walls of the liquid storage tank 10 . In some embodiments, the liquid inlet 110 and the liquid outlet 120 may be disposed on two opposite side walls. For example, the liquid inlet 110 and the liquid outlet 120 may be provided on two opposite first side walls 102 or second side walls 103 respectively. In some embodiments, the liquid inlet 110 and the liquid outlet 120 may be disposed at both diagonal ends of the inner wall of the liquid storage tank 10 . For example, the liquid inlet 110 may be disposed at a top corner where the first side wall 102, the second side wall 103 and the bottom wall 101 are connected, and the top corner is at one end of the diagonal line of the liquid storage tank 10, and the liquid outlet 120 can be placed at the other end of this diagonal. In this embodiment, since the liquid inlet 110 and the liquid outlet 120 are respectively disposed at both ends of the diagonal line of the liquid storage tank 10 , the linear distance between the liquid inlet 110 and the liquid outlet 120 is the longest. A longer flow path is required from when the liquid is injected into the liquid storage tank from the liquid inlet 110 to when it flows out of the liquid storage tank 10 from the liquid outlet 120 . This allows the liquid to fully stir and exchange heat with the original liquid in the liquid storage tank 10 , further promoting the liquid temperature in the liquid storage tank 10 to become consistent.

In some embodiments, the liquid inlet 110 and the liquid outlet 120 may be disposed on the same plane. The term "on the same plane" here may mean that the opening of the liquid inlet 110 and the opening of the liquid outlet 120 are on the same plane. Exemplarily, in the embodiment shown in FIG. 5 , the opening of the liquid inlet 110 and the opening of the liquid outlet 120 are both disposed on the surface of the baffle 240 , so the liquid inlet 110 and the liquid outlet 120 are located in the same plane. .

In some embodiments, the plane where the liquid inlet 110 is located and the plane where the liquid outlet 120 is located are flush with the inner surface of the side wall of the liquid storage tank 10 . As shown in FIG. 5 , in some embodiments, the baffle 240 is embedded on the first side wall 102 of the liquid storage tank 10 , and the surface of the baffle 240 is flush with the inner surface of the side wall of the liquid storage tank 10 . The baffle 240 is provided with a liquid inlet 110 and a liquid outlet 120 , so the plane where the liquid inlet 110 is located and the plane where the liquid outlet 120 is located are flush with the inner surface of the side wall of the liquid storage tank 10 .

In some embodiments, the liquid inlet 110 and the liquid outlet 120 protrude toward the inside of the liquid storage tank 10 relative to the side wall of the liquid storage tank 10 . The protrusion mentioned here means that the plane where the liquid inlet 110 is located and the plane where the liquid outlet 120 is located protrude relative to the inner surface of the side wall of the liquid storage tank 10 . In some embodiments, a first boss and a second boss may be provided on the first side wall 102 . The first boss and the second boss respectively protrude away from the inner surface of the first side wall 102 . And the heights of the first boss and the second boss are different. The liquid inlet 110 and the liquid outlet 120 may be disposed on the first boss and the second boss so as to protrude relative to the first side wall 102 .

In some embodiments, the liquid inlet 11 and the liquid outlet 120 may be disposed on the same plane, and the liquid inlet 110 and the liquid outlet 120 may protrude toward the inside of the liquid storage tank 10 relative to the inner surface of the side wall of the liquid storage tank 10 . out. Exemplarily, the mounting housing 130 is disposed on the inner surface of the first side wall 102 of the liquid storage tank 10 and protrudes toward the interior of the liquid storage tank 10 . The liquid inlet 110 and the liquid outlet 120 may both be provided on the second side wall 132 of the housing. The liquid inlet 110 and the liquid outlet 120 can protrude toward the inside of the liquid storage tank 10 relative to the inner surface of the side wall of the liquid storage tank 10, and the plane of the liquid inlet 110 and the liquid outlet 120 are both relative to the liquid storage tank 10. The inner surface of the first side wall 102 of the liquid tank 10 is convex. In another example, the liquid inlet 110 and the liquid outlet 120 may be disposed on the first boss and the second boss, and the heights of the first boss and the second boss may be the same.

In some embodiments, the plane where the liquid inlet 110 is located and the plane where the liquid outlet 120 is located may not be located on the same plane. As shown in FIG. 11 , in some embodiments, the liquid inlet 110 may be disposed on the second side wall 132 of the mounting housing 130 , and the liquid outlet 120 may be disposed on the first side of the mounting housing 130 . on wall 131. Since the first side wall 131 of the housing and the second side wall 132 of the housing are not parallel, the plane where the liquid inlet 110 is located and the plane where the liquid outlet 120 is located have a certain angle. In this embodiment, the angle between the plane where the liquid inlet 110 is located and the plane where the liquid outlet 120 is located may be equivalent to the angle between the first side wall 131 of the housing and the second side wall 132 of the housing.

In some embodiments, the number of liquid inlets 110 may be one, and the number of liquid outlets 120 may be at least two. As shown in FIG. 5 , in some specific embodiments, the number of liquid outlets 120 may be two, and the two liquid outlets 120 may be arranged along the length direction of the liquid storage tank 10 . In this embodiment, after the liquid enters the liquid storage tank from the liquid inlet, since the liquid has a certain initial velocity, the liquid can flow to the side wall opposite to the liquid inlet 110 and collide with the side wall, thereby forming a split flow. . When the liquid inlet 110 is close to the bottom of the liquid storage tank 10 , the diversion direction of the liquid may include upward flow (ie, a direction away from the bottom of the liquid storage tank 10 ) and rearward (ie, a direction toward the liquid inlet 110 ), wherein upward Part of the liquid flowing in a square direction flows upward to the left, and the other part moves upward to the right. When the two liquid outlets 120 are arranged along the length direction of the liquid storage tank 10, the diverted liquid can flow back to the two liquid outlets 120 under the action of the suction force of the liquid outlets, thereby forming a liquid circulation on the left side and a liquid circulation on the right side. Liquid circulation stirs the liquid in more areas.

In some embodiments, the number of liquid inlets 110 may be multiple. The plurality of liquid inlets 110 can be disposed at the same position or at different positions. For example, the plurality of liquid inlets 110 may be disposed on longer side walls of the liquid storage tank 10 . The plurality of liquid inlets may be arranged along the length direction of the liquid storage tank 10 , and the length direction of the first side 111 of each liquid inlet 110 is parallel to the length direction of the liquid storage tank 10 . In another example, some of the plurality of liquid inlets 110 may be disposed on a longer side wall of the liquid storage tank 10 , and other liquid inlets 110 may be disposed along the length of the liquid storage tank 10 on the shorter side walls.

As shown in FIG. 5 , FIG. 8 and FIG. 12 , in some embodiments, the number of the liquid inlet 110 is one, and the distance between the liquid inlet 110 and each liquid outlet 120 along the height direction of the liquid storage tank 10 is equal. , the distance between the liquid inlet 110 and each liquid outlet 120 along the length direction of the liquid storage tank 10 is equal. The distance between the liquid inlet 110 and the liquid outlet 120 along the height direction of the liquid storage tank 10 can be determined by the first side 111 (shown in FIG. 6 ) of the liquid inlet 110 and the third side of the liquid outlet 120 . Expressed as the distance between edges 121. The distance between the liquid inlet 110 and each liquid outlet 120 along the length direction of the liquid storage tank 10 can be determined by the second side 112 (shown in FIG. 6 ) of the liquid inlet 110 and the fourth side of the liquid outlet 120. expressed as the distance between edges 122. As shown in FIGS. 5 and 6 , in some embodiments, the third side 121 of the liquid outlet 120 may refer to the side with a shorter length of the liquid outlet 120 . The length direction of the third side 121 of the liquid outlet 120 may be parallel to the length direction of the liquid storage tank 10 . In some embodiments, the fourth side 122 of the liquid outlet 120 may refer to the side with a longer length of the liquid outlet 120 . The length direction of the fourth side 122 of the liquid outlet 120 may be parallel to the height direction of the liquid storage tank 10 . FIG. 6 exemplarily shows the positional relationship between the liquid inlet 110 and the liquid outlet 120 provided on the baffle 240 . As shown in FIG. 6 , a filter support 252 is provided on the baffle 240 . There are two liquid outlets 120 , which are located on the left and right sides of the filter support 252 respectively. The distance between the liquid outlet 120 and the liquid inlet 110 located on the left side along the height direction of the liquid storage tank 10 is H1. The distance between the liquid outlet 120 and the liquid inlet 110 located on the right side along the height direction of the liquid storage tank 10 is H2. Among them, H1 can be equal to H2. The distance between the liquid outlet 120 and the liquid inlet 110 located on the left side along the length direction of the liquid storage tank 10 is L1. The distance between the liquid outlet 120 and the liquid inlet 110 located on the right side along the length direction of the liquid storage tank 10 is L2. Among them, L1 can be equal to L2. The equality mentioned here may mean that the ratio of the maximum difference to the maximum value does not exceed a preset error range (for example, 10%, 5%, 1%, etc.). The equal distance between the liquid inlet 110 and each liquid outlet 120 along the height direction of the liquid storage tank 10 may refer to the equal distance between the liquid inlet 110 and the liquid outlet 120 along the height direction of the liquid storage tank 10 . The ratio of the maximum difference to the maximum value of the distance does not exceed 5%.

In some embodiments, the ratio of the distance L3 between the two liquid outlets 120 to the length of the side wall where the liquid outlet 120 is located may range from 0.1 to 0.95. The distance between at least two liquid outlets 120 may refer to the distance between the two closest fourth sides 122 (as shown in FIGS. 5 and 6 ) of the two liquid outlets 120 , which can be determined by the method in FIG. 6 L3 representation. For example, in the embodiment shown in FIG. 5 , the two liquid outlets 120 are located on the first side wall 102 , so the length of the side wall here refers to the length of the first side wall 102 . In some embodiments, the ratio of the distance L3 between the two liquid outlets 120 to the length of the side wall where the liquid outlet 120 is located may range from 0.15 to 0.9. In some embodiments, the ratio of the distance L3 between the two liquid outlets 120 to the length of the side wall where the liquid outlet 120 is located may range from 0.2 to 0.8.

As shown in FIGS. 5 to 8 , in some embodiments, the liquid storage tank 10 may include a first pair of interfaces 201 , a second pair of interfaces 202 , a liquid outlet pipeline 220 and a liquid inlet pipeline 210 . The liquid outlet pipeline 220 can be connected with the second pairing interface 202 and the liquid outlet 120 respectively. The liquid inlet pipeline 210 can be connected with the first pair of interfaces 201 and the liquid inlet 110 respectively. Among them, the docking interface may refer to the connecting port where the pipeline is connected to other devices and components.

In this embodiment, the liquid in the liquid storage tank 10 can enter the liquid outlet pipe 220 from the liquid outlet 120, and then flow out from the second docking port 202 through the liquid outlet pipe 220. In addition, the liquid can enter the liquid inlet pipe 210 through the first pair of interfaces 201, and then flow into the inside of the liquid storage tank 10 from the liquid inlet 110 through the liquid inlet pipe 210. For example, the liquid inlet pipeline 210 and the liquid outlet pipeline 220 can be coupled with the temperature adjustment assembly 30 through the first pair of interfaces 201 and the second pair of interfaces 202 respectively. The temperature adjustment component 30 can heat or cool the liquid flowing out of the second pair of interfaces 202, and then transport it to the liquid inlet pipe 210 through the first pair of interfaces 201, and then transport it to the liquid storage tank 10.

As shown in FIG. 5 , in some specific embodiments, the baffle 240 may be embedded on the first side wall 102 of the liquid storage tank 10 . The baffle 240 is provided with a liquid inlet 110 and a liquid outlet 120 . Also connected to the baffle 240 is a protrusion located outside the side wall of the liquid storage tank 10 . In some embodiments, the protruding portion may have an accommodation space, and the liquid outlet pipeline 220 and the liquid inlet pipeline 210 may be accommodated in the accommodation space. The first pair of interfaces 201 and the second pair of interfaces 202 are provided on the top of the protruding portion and are arranged along the length direction of the liquid storage tank 10 .

In some embodiments, the number of liquid outlet pipes 220 and the number of second pairs of interfaces 202 may be equal to the number of liquid outlets 120 . For example, in the embodiment shown in FIG. 8 , the number of liquid outlets 120 is two, so the number of liquid outlet pipes 220 and the second docking interface 202 can be two, and each liquid outlet pipe 220 A liquid outlet 120 and a second pair of interfaces 202 are connected respectively.

In some embodiments, the liquid outlet pipeline 220 may include two branch pipelines 221. Each branch pipe 221 is connected to a second docking port 202 and a liquid outlet 120 respectively. The liquid inlet pipe 210 may include one pipe, and the liquid inlet pipe 210 may be disposed between two liquid outlet pipes 220 .

As shown in FIGS. 8 and 9 , in some embodiments, the outer contour of the liquid outlet pipeline 220 may be Y-shaped, and the liquid outlet pipeline 220 may include a main pipeline 222 connected with two branch pipelines 221 . The main pipeline 222 can be connected to the second pairing interface 202, and the two branch pipelines 221 can be connected to a liquid outlet 120 respectively. In this embodiment, two branch pipes 221 are connected to the second docking port 202 through a main pipe 222, and the liquid in the liquid storage tank 10 can flow into the corresponding branch pipes 221 from the two liquid outlets 120, respectively. Then it is collected into the main pipeline 222 and flows out from the second pair of interface 202 via the main pipeline 222 . Since the number of the second pair of interfaces 202 is reduced, the space size of the liquid outlet pipeline 220 can be effectively reduced.

As shown in FIG. 11 , in some embodiments, at least part of the liquid inlet pipeline 210 is located above the highest water level of the liquid storage tank 10 and close to the first pair of interfaces 201 . At least part of the liquid outlet pipe 220 is located above the highest water level of the liquid storage tank 10 and close to the second docking port 202 . In some cases, the liquid pressure at the liquid inlet 110 may be reduced. Reducing the liquid pressure can facilitate the liquid to enter the liquid storage tank 10 from the liquid inlet 110, making the liquid agitation effect better. In some cases, it can be avoided that the liquid in the liquid storage tank 10 enters the pipeline connected to the host 200 (for example, the pipeline related to the temperature adjustment assembly 30), causing the pipeline to stink. In other cases, it can be avoided that the liquid in the liquid storage tank 10 flows out of the second pairing interface 202 when the second pairing interface 202 is disconnected from other structures (eg, the pumping assembly 230).

As shown in FIGS. 2 , 5 and 8 to 10 , in some embodiments, the liquid storage tank 10 may also be connected to a pumping device 230 . The pumping device 230 can cooperate with the liquid inlet pipe 210 and the liquid outlet pipe 220 respectively to pump liquid into the liquid inlet pipe 210 and extract the liquid in the liquid outlet pipe 220 .

In some embodiments, the specific cooperation manner between the pumping device 230 and the liquid inlet pipeline 210 and the liquid outlet pipeline 220 is related to the type of the pumping device 230 . In some embodiments, the type of pumping device 230 may include a reciprocating pump, a plunger pump, a piston pump, a diaphragm pump, a rotor pump, a peristaltic pump, and the like. For ease of understanding, a peristaltic pump is used as an example. The peristaltic pump can be installed outside the liquid inlet pipe 210 and the liquid outlet pipe 220, and pumps the liquid by squeezing the liquid inlet pipe 210 and the liquid outlet pipe 220. liquid in the liquid pipeline 210 and the liquid outlet pipeline 220. In another example, the pumping device 230 may also be a hydraulic pump. The hydraulic pump may be directly connected to the liquid inlet pipeline 210 and the liquid outlet pipeline 220 to pump the liquid by changing the pressure in the pipelines.

In some embodiments, the liquid inlet pipeline 210 and the liquid outlet pipeline 220 can cooperate with an external temperature adjustment assembly 30 , and the temperature adjustment assembly 30 is used to adjust the temperature of the liquid in the liquid storage tank 10 . For example, the pumping device 230 can transport the liquid extracted from the liquid outlet pipe 220 to the temperature adjustment assembly 30, and the temperature adjustment assembly 30 adjusts the temperature of the liquid (eg, heats or cools). For example, the temperature adjustment assembly 30 may include a heating tube and a heating element disposed outside the heating tube. The liquid extracted from the liquid outlet pipe 220 can be transported to the heating tube, and the heating element is used to heat the heating tube, thereby heating the heating tube. liquid is heated. The liquid processed by the temperature adjustment assembly 30 is then transported to the liquid inlet pipeline 210 by the pumping device 230 .

In some embodiments, the cooking device 100 may further include a vacuum pump, which may discharge at least part of the residual liquid in the pipelines related to liquid circulation (for example, the liquid inlet pipeline 210, the liquid outlet pipeline 220, etc.) , thereby preventing residual liquid from flowing into the liquid storage tank 10 and affecting the quality of the liquid in the liquid storage tank 10 when the cooking device 100 is used next time.

In some embodiments, cooking device 100 may include a vacuum pump. The vacuum pump is installed on the pipeline related to liquid circulation. After the cyclic heating or cyclic refrigeration process of the cooking device 100 ends, the pumping device 230 stops working, and the liquid no longer circulates. At this time, the vacuum pump can be started. When the vacuum pump is in working state, the residual liquid in the pipeline related to the liquid circulation can be discharged to the liquid storage tank 10 through the self-priming function. The self-priming function of the vacuum pump can refer to: when the vacuum pump is working, it can pump air to form a negative pressure after vacuum in the pipelines related to the liquid circulation. The residual liquid in the pipelines related to the liquid circulation is absorbed by the negative pressure. discharge.

In some embodiments, after the vacuum pump discharges the residual liquid in the pipeline related to the liquid circulation, an air segment will be formed in the pipeline related to the liquid circulation. When air segments are formed in the pipelines related to liquid circulation, there will also be air segments inside the pumping device 230, resulting in the pumping device 230 not being filled with liquid, which will make the pumping device 230 unable to absorb liquid or absorbing liquid slowly. Thus, the normal operation of the cooking device 100 is affected. In this case, the vacuum pump can be started before the pumping device 230 of the cooking device 100 is operated, and the self-priming function of the vacuum pump is used to form a vacuum negative pressure in the pipeline related to the liquid circulation, thereby generating suction force that will interact with the liquid. The air in the circulation-related pipelines is sucked away, so that the liquid in the liquid storage tank 10 can fill or partially fill the pumping device 230, so that the pumping device 230 or the cooking device 100 can work normally.

By providing a vacuum pump in the cooking device 100, on the one hand, after the liquid circulation heating or cooling process of the cooking device 100 is completed, the self-priming function of the vacuum pump can be used to discharge the residual liquid in the pipelines related to the liquid circulation to the liquid storage tank. 10, thereby ensuring that there is no liquid residue in the pipelines related to liquid circulation. On the other hand, before the liquid circulation heating or cooling process of the cooking device 100 starts (that is, the pumping device 230 is started), the self-priming function of the vacuum pump is used to generate suction, thereby removing the air in the pipelines related to the liquid circulation. The liquid in the liquid storage tank 10 can be sucked away so that the liquid in the liquid storage tank 10 can flow into the pumping device 230 through the pipeline related to liquid circulation, thereby ensuring that the pumping device 230 can work normally.

In some embodiments, the ratio between the liquid circulation flow rate in the liquid circulation related pipeline and the volume of the liquid storage tank 10 may range from 1:6 to 1:1, so that the liquid in the liquid storage tank 10 can The processing is completed in a short period of time through the relevant pipelines of the liquid circulation. In some embodiments, the ratio between the liquid circulation flow rate in the liquid circulation related pipeline and the volume of the liquid storage tank 10 may range from 1:5 to 1:2.5. In some embodiments, the ratio between the liquid circulation flow rate in the liquid circulation related pipeline and the volume of the liquid storage tank 10 may range from 1:4.5 to 1:2. For example, if the liquid circulation flow in the liquid circulation related pipeline is 5.4L/min and the volume of the liquid storage tank 10 is 12L, then the ratio between the liquid circulation flow in the liquid circulation related pipeline and the volume of the liquid storage tank 10 is 0.45. For example, when the liquid passing through the pipeline related to the liquid circulation can be heated, the above proportion range can increase the heating rate of the liquid in the liquid storage tank 10, shorten the time that the entire liquid in the liquid storage tank 10 needs to be heated, and reduce the storage time. The heat of the liquid in the liquid tank 10 is lost, which improves the stability of the temperature of the liquid in the liquid storage tank 10 and allows precise temperature control in the liquid storage tank 10 . In some embodiments, the liquid circulation flow rate in the liquid circulation-related pipelines may refer to the total volume flow rate of the liquid in the circulation system when liquid circulation is performed in the liquid circulation-related pipelines.

In some embodiments, the flow rate of the vacuum pump may range from 1L/min to 2.5L/min. In some embodiments, the flow rate of the vacuum pump may range from 1.25L/min to 2.25L/min. In some embodiments, the flow rate of the vacuum pump may range from 1.5L/min to 2L/min. As an example only, the flow rate of the vacuum pump is 1.5L/min.

In some embodiments, the flow rate of liquid flowing into the interior of the liquid storage tank 10 through the liquid inlet 110 will affect the liquid circulation effect. For example, when the flow rate of the liquid is small, the liquid may not hit the opposite side wall after being ejected through the liquid inlet 110 (that is, the side wall opposite to the side wall where the liquid inlet 110 is located), causing the liquid to move toward The surroundings of the liquid inlet 110 are diffused and no circulation can be formed. The liquid stirring area is small, and the liquid in the liquid storage tank 10 cannot be fully mixed. In some embodiments, it is necessary to control the flow rate of liquid into the interior of the liquid storage tank 10 through the liquid inlet 110 to ensure that the liquid can hit the side wall opposite to the liquid inlet 110 .

In some embodiments, the flow rate of liquid flowing into the interior of the liquid storage tank 10 through the liquid inlet 110 may be related to the preset flow rate of the pumping device 230 (ie, the flow rate of the pumping device 230). In some embodiments, the flow rate of the pumping device 230 may range from 3L/min to 10L/min. In some embodiments, the flow rate of the pumping device 230 may range from 4L/min to 9L/min. In some embodiments, the flow rate of the pumping device 230 may range from 5L/min to 8L/min. In some embodiments, the flow rate of the pumping device 230 may range from 6L/min to 7L/min. By way of example only, the flow rate of the pumping device 230 may be 8 L/min.

In some embodiments, the larger the volume of the liquid storage tank 10, the more liquid it can hold. Based on what is described in one or more embodiments of this specification, when the liquid flows into the inside of the liquid storage tank 10 from the liquid outlet 120, the liquid in the liquid storage tank 10 can be stirred. If the volume of the liquid storage tank 10 is large and the liquid flow rate at the liquid port 110 is small, the liquid can be stirred in a smaller range after flowing from the liquid outlet 120 into the liquid storage tank 10. For the inside of the liquid storage tank 10 The stirring effect of the liquid is not good, and the liquid in the liquid storage tank 10 cannot be fully mixed. In some embodiments, the liquid flow rate at the liquid inlet 110 may be equal to the flow rate of the pumping device 230 .

In some embodiments, the value range of the ratio between the volume of the liquid storage tank 10 and the liquid flow rate at the liquid inlet 110 may include 1 min to 5 min. In some embodiments, the value range of the ratio between the volume of the liquid storage tank 10 and the liquid flow rate at the liquid inlet 110 may include 1 min to 3 min. In some embodiments, the value range of the ratio between the volume of the liquid storage tank 10 and the liquid flow rate at the liquid inlet 110 may include 1 min to 2 min. In some embodiments, the ratio between the volume of the liquid storage tank 10 and the liquid flow rate at the liquid inlet 110 may be 1.5 min. In some embodiments, the volume of the liquid storage tank 10 may be what the liquid storage tank 10 can accommodate. The volume of liquid. In some embodiments, the volume of the liquid storage tank 10 may be the volume of liquid corresponding to the highest liquid level line in the liquid storage tank 10 .

In some embodiments, the liquid flow rate of the liquid inlet 110 may range from 1 m/s to 1.5 m/s. In some embodiments, the liquid flow rate of the liquid inlet 110 may range from 1.1 m/s to 1.3 m/s. In some embodiments, the liquid flow rate of the liquid inlet 110 may be 1.2 m/s.

As shown in Figure 3, Figure 5, Figure 8 to Figure 10 and Figure 12, this specification also provides a liquid inlet and outlet assembly. In some embodiments, the liquid inlet and outlet assembly 20 may include a liquid outlet 120, a liquid inlet 110, a liquid outlet pipeline 220 connected to the liquid outlet 120, and a liquid inlet pipeline 210 connected to the liquid inlet 110. The size of the liquid inlet 110 along the first direction may be larger than the size of the liquid inlet 110 along the second direction. The first direction and the second direction may be represented by arrows in FIG. 12 . Both the liquid inlet pipeline 210 and the liquid outlet pipeline 220 may include a liquid output end and a liquid input end. The liquid inlet 110 is provided at the liquid output end of the liquid inlet pipeline 210 . Liquid can enter the liquid inlet pipeline 210 through the liquid input end of the liquid inlet pipeline 210 , and then flow out through the liquid inlet 110 . The liquid outlet 120 is provided at the liquid output end of the liquid outlet pipeline 220 . Liquid can enter the liquid outlet pipeline 220 through the liquid outlet 120 , and then flow out through the liquid output end of the liquid outlet pipeline 220 . Figures 9 and 10 exemplarily show the flow direction of liquid in the liquid inlet pipe 210 and the liquid outlet pipe 220.

In some cases, since the size of the liquid inlet 110 in the first direction is larger than the size in the second direction, the opening of the liquid inlet 110 is flat. When the liquid flows out (eg, sprays) from the liquid inlet 110 , it will move to the front and both sides of the liquid inlet 110 , thereby forming an inverted triangle, sector, or trapezoid shape (this shape can also be approximately regarded as a sector). The front of the liquid inlet 110 mentioned here may refer to the direction away from the liquid inlet 110 along the third direction, and the third direction is perpendicular to the first direction and the second direction. The two sides of the liquid inlet 110 may refer to the two sides of the opening of the liquid inlet 110 along the first direction. The third direction may refer to a direction perpendicular to the first direction and the second direction.

In some embodiments, the liquid inlet and outlet assembly 20 can be combined with any liquid storage container. In some embodiments, the liquid inlet and outlet assembly 20 may be a part of the liquid storage tank 10. For example, the liquid inlet and outlet assembly 20 may be a part of the liquid storage tank 10 of the cooking device 100 in the aforementioned embodiments, as shown in FIGS. 5 and 11 The liquid storage tank 10 shown can be used for low-temperature cooking of food materials. The liquid inlet and outlet assembly 20 can be used to transport liquid to the inside of the liquid storage container and to drain the liquid from the inside of the liquid storage container. For example, the liquid can enter the inside of the liquid storage container from the liquid inlet 110 via the liquid inlet pipe 210 . The liquid inside the liquid storage container can flow out from the liquid outlet 120 through the liquid outlet pipe 220 . In this example, the first direction may refer to the length direction of the liquid storage tank 10 , such as the direction indicated by arrow X in FIG. 5 . The second direction may refer to the height direction of the liquid storage tank 10, such as the direction indicated by arrow H in FIG. 5 . The third direction may refer to the thickness direction of the liquid storage tank 10, such as the direction indicated by arrow Y in FIG. 5 . In some embodiments, the liquid input end of the liquid inlet pipeline 210 may be equal to the first pair of interfaces 201 in other embodiments of this specification. The liquid output end of the liquid outlet pipeline 220 may be equivalent to the second pair of interfaces 202 in other embodiments of this specification.

In some cases, when the liquid inlet and outlet assembly 20 is used in a liquid storage container (for example, the liquid storage tank 10 ), when the fan-shaped liquid hits the side wall opposite to the side wall where the liquid inlet 110 is located, the fan-shaped liquid will Forming shunts, upward, downward and backward flows. The diverted liquid finally flows out of the liquid storage tank 10 through the liquid outlet 120 . In some cases, if the liquid inlet 110 is disposed on the side wall of the liquid storage tank 10, when the fan-shaped liquid moves to the side wall opposite to the liquid inlet 110, the liquid will form an inclination angle with the side wall. The inclination angle allows the liquid to continue flowing to both sides of the side wall after hitting the side wall of the liquid storage tank 10 without being dispersed, which allows the liquid to continue to stir the original liquid in the liquid storage tank 10 . In other cases, the liquid may form a circular flow during the process from the liquid inlet 110 entering the interior of the liquid storage tank 10 to entering the liquid outlet 120 , thereby stirring the liquid in the liquid storage tank 10 . Due to the larger range of the circulation, more of the original liquid in the liquid storage tank 10 can be stirred, which has a good effect on improving the uniformity of the liquid in the liquid storage tank 50 , which in turn can make the food in the liquid storage tank 10 different. The positions are heated evenly, which ultimately makes the doneness of the ingredients in different positions consistent and tastes better.

In some embodiments, for more details about the liquid inlet 110 and the liquid outlet 120, please refer to the description of the aforementioned embodiments related to the liquid storage tank 10, and will not be described again here. For more details about the structure of the liquid inlet and outlet assembly 20, please refer to the descriptions of other embodiments of this specification, and will not be described again here.

In some embodiments, the cooking device 100 may be a combination of the liquid storage tank 10 and the liquid inlet and outlet assembly 20 in one or more of the foregoing embodiments, and further include one or more of the liquid storage tank 10 and the liquid inlet and outlet assembly 20 . Multiple functions. In some embodiments, the cooking device 100 may also only have one or more functions possessed by the liquid storage tank 10 and the liquid inlet and outlet assembly 20 .

In some embodiments, the cooking device 100 may include a liquid storage tank 10 and a piping system 40 . The liquid storage tank 10 may include a liquid inlet 110 and a liquid outlet 120 , and the pipeline system 40 may be connected with the liquid inlet 110 and the liquid outlet 120 . The pipeline system 40 may include a first pipeline 410 , a second pipeline 420 , and a pumping device 230 in communication with the first pipeline 410 and the second pipeline 420 . The first pipeline 410 can be connected with the liquid inlet 110 , and the second pipeline 420 can be connected with the liquid outlet 120 . The pumping device 230 may have a preset flow rate and can cause the liquid in the liquid storage tank 10 to flow into the pipeline system 40 from the liquid outlet 120 and be sprayed into the liquid storage tank 10 from the liquid inlet 110 . And the liquid sprayed from the liquid inlet 110 can reach the opposite side wall of the side wall where the liquid inlet 110 is located, forming a liquid injection area on the opposite side wall. In the length direction of the liquid storage tank 10, the ratio of the size of the liquid injection area to the size of the opposite side wall may range from 0.2 to 1. In some embodiments, the ratio of the size of the liquid ejection zone to the size of the opposite side wall may range from 0.25 to 0.9. The ratio of the size of the liquid ejection zone to the size of the opposite side wall may range from 0.3 to 0.8.

After the liquid is ejected from the liquid inlet 110 , it is connected to the other first side wall 102 . The area where the wall 102 contacts is the liquid ejection area. In this implementation, when the liquid hits the side wall opposite the side wall where the liquid inlet 110 is located, a split flow will be formed that moves in multiple directions, and finally flows out through the liquid outlet 120 . During the process when the liquid enters the inside of the liquid storage tank 10 from the inlet to the inside of the liquid storage tank 10 and enters the liquid outlet 120, a circular flow can be formed during the process when the liquid enters the inside of the liquid storage tank 10 from the liquid inlet 110 to the liquid outlet 120. , stirring the liquid in the liquid storage tank 10. In some embodiments, if the size of the contact area (ie, the liquid ejection area) is too large, the liquid will be blocked by the second side wall 103 after hitting the first side wall 102 . Backflow may occur when the liquid hits the second side wall 103 of the liquid storage tank 10 . The reverse flow may collide with the liquid ejected from the liquid inlet 110 , thereby weakening the stirring effect of the liquid on the original liquid in the liquid storage tank 10 . If the size of the liquid injection area is too small, the liquid shunt formed after the liquid hits the first side wall 102 can stir less liquid, and the original liquid in the liquid storage tank 10 cannot be fully stirred.

In some embodiments, the size of the liquid injection zone may be related to the liquid flow rate at the liquid inlet 110 . In some embodiments, the liquid flow rate at the liquid inlet 110 may range from 1 m/s to 1.5 m/s. In some embodiments, the liquid flow rate at the liquid inlet 110 may range from 1.1 m/s to 1.3 m/s.

For example, in the embodiments shown in FIGS. 5 and 11 , the number of liquid outlets 120 is two, so the sum of the cross-sectional areas of the liquid outlets 120 is equal to the sum of the cross-sectional areas of the two liquid outlets 120 . In some embodiments, the ratio of the total cross-sectional area of the liquid outlet 120 to the cross-sectional area of the liquid inlet 110 may range from 1.75 to 2.75. In some embodiments, the ratio of the total cross-sectional area of the liquid outlet 120 to the cross-sectional area of the liquid inlet 110 may range from 2 to 2.5.

In some embodiments, the sum of the cross-sectional areas of the liquid outlets 120 is related to the inlet cross-sectional area of the pumping device 230 . The inlet of the pumping device 230 may refer to the communication port between the pumping device 230 and the second pipeline 420 . As shown in Figure 8, in some embodiments, the pipeline system 40 may include a first pair of interfaces 201 and a second pair of interfaces 202, and the liquid outlet pipeline 220 (ie, the second pipeline 420) may pass through the second pair of interfaces. 202 Cooperate with other devices or components. For example, the liquid outlet line 220 can cooperate with the pumping device 230 (eg, a hydraulic pump) through the second docking interface 202 . Therefore, in this embodiment, the inlet of the pumping device 230 may refer to the second pair of interface 202 .

In some embodiments, the liquid inlet 110 and the liquid outlet 120 can be the same as or similar to the liquid inlet 110 and the liquid outlet 120 in FIGS. 5 to 12 , and more details can be found in the relevant embodiments in FIGS. 5 to 12 Description will not be repeated here.

In some embodiments, the liquid storage tank 10 can be the same as or similar to the liquid storage tank 10 in Figures 5 to 11. More details can be found in the description of the relevant embodiments in Figures 5 to 11, and will not be described again here.

The pipeline system 40 may refer to a pipeline assembly connected to the liquid inlet 110 and the liquid outlet 120 for transporting liquid. In some embodiments, the piping system 40 may be used to transport liquid to the interior of the liquid storage tank 10 and to drain the liquid from the interior of the liquid storage tank 10 . In some embodiments, the first pipeline 410 may be the same as or similar to the liquid inlet pipeline 210 in the previous embodiment, and the second pipeline 420 may be the same as or similar to the liquid outlet pipeline 220 in the previous embodiment. In some embodiments, the pipeline system 40 may also include a baffle 240, a pipeline support plate 260, a filter assembly 250, and a seal 270, about which further description can be found in the embodiment associated with Figure 8, here No longer.

In some embodiments, the pipeline system 40 may further include a temperature adjustment component 30 , and the temperature adjustment component 30 may adjust the temperature of the liquid flowing out through the second pipeline 420 . For example, the temperature adjustment assembly 30 may include a heating pipe connected between the first pipeline 410 and the second pipeline 420 . The heating tube can heat the liquid in the first pipeline 410 and/or the second pipeline 420 . The pumping device 230 can transport the liquid treated by the heating tube to the inside of the liquid storage tank 10 through the first pipeline 410 and the liquid inlet 110 .

In some embodiments, when the liquid flows out from the liquid inlet 110, it can reach the opposite side wall of the side wall where the liquid inlet 110 is located, forming a liquid injection area on the opposite side wall. In addition, in the length direction of the liquid storage tank 10 , when the ratio of the size of the liquid injection zone to the size of the opposite side wall is within a preset range, it means that the liquid can form a circulation in the liquid storage tank 10 , thereby causing damage to the liquid storage tank 10 Stir more liquid inside to make the liquid more fully mixed, eventually causing the liquid temperature to become consistent. Therefore, in some embodiments, the ratio of the size of the liquid injection zone to the size of the opposite side wall needs to be controlled within a preset range to achieve the best stirring effect.

In some embodiments, the size of the liquid injection zone may be related to the preset flow rate of the pumping device 230. In some embodiments, the value range of the preset flow rate may include 3L/min ~ 10L/min. In some embodiments, the value range of the preset flow rate may include 4L/min ~ 9L/min. In some embodiments, the preset flow rate may be 8L/min.

In some embodiments, the liquid inlet 110 may be disposed on a longer side wall of the liquid storage tank 10 . Exemplarily, in the embodiments shown in FIGS. 5 and 11 , the liquid inlet 110 is provided on the first side wall 102 of the liquid storage tank 10 through the baffle 240 and the mounting housing 130 respectively. In some cases, the liquid inlet 110 is disposed on a longer side wall of the liquid storage tank 10 , so the distance between the side wall where the liquid inlet 110 is located and the side wall opposite to the side wall where the liquid inlet 110 is located is shorter. (The distance between the two first side walls 102 may be approximately equal to the length of the second side wall 103). Therefore, the distance required for the liquid to flow into the liquid storage tank 10 through the liquid inlet 110 and hit the opposite side wall is shorter (that is, the liquid flow stroke is shorter), which facilitates the formation of liquid circulation.

In order to make it easier for the liquid to form a circulation and improve the stirring effect of the liquid in the liquid storage tank 10 , in some embodiments, the liquid inlet 110 and the liquid outlet 120 may be located on the same side wall of the liquid storage tank 10 . Exemplarily, in the embodiments shown in Figures 5 and 11, the first side wall 102 of the liquid storage tank 10 is provided with a baffle 240 and a mounting housing 130, respectively. The baffle 240 and the mounting housing 130 are respectively Both are provided with a liquid inlet 110 and a liquid outlet 120 . Therefore, in the embodiment shown in FIG. 5 and FIG. 11 , the liquid inlet 110 and the liquid outlet 120 are both disposed on the first side wall 102 of the liquid storage tank 10 .

In some embodiments, the liquid inlet 110 may be disposed near the bottom of the liquid storage tank 10 . In some embodiments, the distance between the liquid inlet 110 and the bottom of the liquid storage tank 10 may range from 2 cm to 10 cm. In some embodiments, the distance between the liquid inlet 110 and the bottom of the liquid storage tank 10 may range from 2.5 cm to 8 cm. In some embodiments, the distance between the liquid inlet 110 and the bottom of the liquid storage tank 10 may range from 3 cm to 7 cm.

In some embodiments, the positional relationship between the liquid inlet 110 and the liquid outlet 120 will affect the overall liquid circulation stirring effect. In some embodiments, the liquid inlet 110 may be disposed below the liquid outlet 120 , and the height of the liquid outlet 120 is not higher than the lowest water level of the liquid storage tank 10 .

In some embodiments, the size of the liquid inlet 110 along the length direction of the liquid storage tank 10 may be larger than the size of the liquid inlet 110 along the height direction of the liquid storage tank 10 .

In some embodiments, the ratio of the size of the liquid inlet 110 along the length direction of the liquid storage tank 10 to the size of the liquid inlet 110 along the height direction of the liquid storage tank 10 may range from 1.1 to 7.5. In some embodiments, the ratio of the size of the liquid inlet 110 along the length direction of the liquid storage tank 10 to the size of the liquid inlet 110 along the height direction of the liquid storage tank 10 may range from 1.3 to 6. In some embodiments, the ratio of the size of the liquid inlet 110 along the length direction of the liquid storage tank 10 to the size of the liquid inlet 110 along the height direction of the liquid storage tank 10 may range from 1.5 to 5.

In some embodiments, the ratio of the size of the liquid inlet 110 along the length direction of the liquid storage tank 10 to the length of the liquid storage tank 10 may range from 1/20 to 2/15. In some embodiments, the ratio of the size of the liquid inlet 110 along the length direction of the liquid storage tank 10 to the length of the liquid storage tank 10 may range from 1/18 to 1/15. In some embodiments, the ratio of the size of the liquid inlet 110 along the length direction of the liquid storage tank 10 to the length of the liquid storage tank 10 may range from 1/16 to 1/15.

In some embodiments, the angle α at which the second side 112 of the liquid inlet 110 is tilted outward may range from 0 to 90 degrees. In some embodiments, the outward tilt angle α may range from 30 degrees to 60 degrees. In some embodiments, the outward tilt angle α may be 45 degrees.

In some embodiments, the number of liquid inlets 110 may be one, and the number of liquid outlets 120 may be at least two. As shown in FIG. 5 , in some specific embodiments, the number of liquid outlets 120 may be two, and the two liquid outlets 120 may be arranged along the length direction of the liquid storage tank 10 . In some embodiments, the liquid inlet 110 and the liquid outlet 120 can be the same as or similar to the liquid inlet 110 and the liquid outlet 120 in FIGS. 5 to 12 , and more details can be found in the relevant embodiments in FIGS. 5 to 12 Description will not be repeated here.

In some embodiments, the liquid storage tank 10 may be the same as or similar to the liquid storage tank 10 in FIGS. 5 to 11 . More details can be found in the description of the relevant embodiments in FIGS. 5 to 11 and will not be described again here.

This specification also provides another cooking device 100. As shown in FIGS. 4 and 7 , in some embodiments, the cooking device 100 may include a liquid storage tank 10 and a pipeline system 40 . The liquid storage tank 10 may include a liquid inlet 110 and a liquid outlet 120 , and the pipeline system 40 may be connected with the liquid inlet 110 and the liquid outlet 120 . The pipeline system 40 may include a first pipeline 410 , a second pipeline 420 , and a pumping device 230 in communication with the first pipeline 410 and the second pipeline 420 . The first pipeline 410 can be connected with the liquid inlet 110 , and the second pipeline 420 can be connected with the liquid outlet 120 . The liquid inlet 110 includes an outwardly inclined side, and the outwardly inclined angle α ranges from 0 to 90 degrees. In some embodiments, the outward tilt angle α may range from 30 degrees to 60 degrees. In some embodiments, the outward tilt angle α may be 45 degrees.

In some embodiments, when the liquid inlet 110 is disposed on the side wall of the liquid storage tank 10 , the two shorter sides of the liquid inlet 110 may be inclined outward at a certain angle α. In some cases, after the liquid enters the inside of the liquid storage tank 10 from the liquid inlet 110, it is easier to form a fan-shaped, trapezoidal or inverted triangle liquid. For example, as shown in FIGS. 5 , 7 and 12 , the liquid inlet 110 may be provided on the longer first side wall 102 of the liquid storage tank 10 . The length direction of the two longer first sides 111 of the liquid inlet 110 may be parallel to the length direction of the first side wall 102 . The length direction of the two shorter second sides 112 of the liquid inlet 110 may be parallel to the length direction of the second side wall 103 . The end of the second side 112 close to the inside of the liquid storage tank 10 is further away from the central axis O of the liquid inlet 110 than the end far away from the inside of the liquid storage tank 10 .

As shown in FIG. 4 , FIG. 5 and FIG. 11 , this specification also provides a cooking device 100 . The cooking device 100 may include a liquid storage tank 10 and a piping system 40 . The liquid storage tank 10 may include a liquid inlet 110 and a liquid outlet 120 , and the pipeline system 40 may be connected with the liquid inlet 110 and the liquid outlet 120 . The pipeline system 40 may include a first pipeline 410 , a second pipeline 420 , and a pumping device 230 in communication with the first pipeline 410 and the second pipeline 420 . The first pipeline 410 can be connected with the liquid inlet 110 , and the second pipeline 420 can be connected with the liquid outlet 120 . The liquid inlet 110 and the liquid outlet 120 may be located on the same side wall of the liquid storage tank 10 .

In this embodiment, the liquid sprayed from the liquid inlet 110 may collide with the side wall opposite the liquid inlet 110 , and then form several liquid shunts flowing in different directions (eg, upper left, upper right, etc.). Since the liquid inlet 110 and the liquid outlet 120 are disposed on the same side wall, under the suction of the liquid outlet 120, several partial flows will return to the side wall where the liquid inlet 110 is located along different paths, and finally converge at the outlet. 120 liquid ports. In the process of several partial flows returning to the liquid outlet 120, the several partial flows can stir the liquid in different areas, thereby causing more liquid to mix, further promoting the liquid temperature in the liquid storage tank 10 to become consistent.

In some embodiments, the liquid inlet 110 may be disposed on a longer side wall of the liquid storage tank 10 . Exemplarily, in the embodiments shown in Figures 5 and 11, the liquid inlet 110 is provided on the first side wall 102 of the liquid storage tank 10 through the baffle 240 and the mounting housing 130 respectively.

In some embodiments, the liquid inlet 110 may be disposed at a middle position of the side wall of the liquid storage tank 10 along the length direction of the liquid storage tank 10 .

In order to further improve the stirring effect of the liquid sprayed from the liquid inlet 110 on the original liquid in the liquid storage tank 10, the structure of the liquid inlet 110 can be improved. In some embodiments, a tubular member may be provided at the liquid inlet 110 , and the tubular member may have a certain elasticity and be capable of elastic deformation under the action of external force. One end of the tubular member is connected to the liquid inlet 110 , and the liquid sprayed from the liquid inlet 110 can be sprayed into the liquid storage tank 10 through the tubular member. The liquid ejected from the liquid inlet 110 can exert force on the inner wall of the tubular member, thereby causing the tubular member to elastically deform (eg, bend). During this process, the opening orientation of the tubular member may continuously change, ultimately causing the direction in which the liquid is ejected from the tubular member to continuously change. In some cases, providing a tubular member at the liquid inlet 110 can not only make the liquid flow in the liquid storage tank 10 more chaotic. The range of liquid stirring can also be increased, so that the amount of liquid participating in the stirring is larger, the stirring effect of the liquid in the liquid storage tank 10 is better, and the mixing of the liquid is further promoted.

Referring to FIG. 4 , in some embodiments, the temperature adjustment component 30 may also include a temperature monitoring unit, such as a temperature sensor. The control component 50 of the host computer 200 can control the liquid inlet mode of the liquid inlet 110 according to the sensing signal sent by the temperature sensor, so that the liquid temperature at various locations in the liquid storage tank 10 tends to be consistent. Among them, the temperature sensor can be used to measure the temperature of the liquid in the liquid storage tank 10 . The liquid inlet mode of the liquid inlet 110 may include whether to inject liquid, the speed (or flow rate), temperature, injection direction and other motion parameters of the liquid ejected from the liquid inlet 110 . As an example, when the control component 50 determines that the difference between the liquid temperature at a certain location in the liquid storage tank 10 and the liquid temperature at other locations is too large, the control component 50 may increase the speed of the liquid ejected from the liquid inlet 110 . Increasing the speed of the liquid ejected from the liquid inlet 110 can improve the stirring effect on the original liquid in the liquid storage tank 10 , thereby reducing the temperature difference of the liquid at various locations in the liquid storage tank 10 .

In some embodiments, types of temperature sensors may include thermocouple sensors, thermistor sensors, resistive temperature sensors, and the like. In some embodiments, the temperature sensor can be placed directly in the liquid storage tank 10 to more conveniently measure the temperature. In some embodiments, the number of temperature sensors may be one or multiple. Multiple temperature sensors may be disposed at different locations in the liquid storage tank 10 . For example, multiple temperature sensors, some of which may be placed close to the liquid inlet 110 , such as near point a in FIG. 13 . Others of the plurality of temperature sensors may be placed at positions far away from the liquid inlet 110 , such as positions near point b and point c in FIG. 13 . In some embodiments, multiple temperature sensors can be arranged according to certain rules. For example, when the liquid inlet 110 and the liquid outlet 120 are located on the diagonal line of the liquid storage tank 10, multiple temperature sensors may be disposed at equal intervals along the diagonal direction. In another example, multiple temperature sensors may be disposed at equal intervals along the height direction of the liquid storage tank 10 . In some embodiments, the control component 50 may obtain the liquid temperature at one or more locations in the fluid storage tank 10 based on sensing signals from temperature sensors at one or more locations in the fluid storage tank 10 . The temperature distribution of the liquid in the liquid storage tank 10 is determined based on the liquid temperature at one or more locations in the liquid storage tank 10 .

In some embodiments, the control assembly 50 may control the speed of the liquid ejected from the liquid inlet 110 by controlling the pumping device 230 . For example, the preset flow rate of the pumping device 230 is reduced or increased to reduce or speed up the speed of liquid ejection from the liquid inlet 110 . In some embodiments, the liquid inlet 110 may be provided with a first valve, and the first valve may communicate/connect with the liquid inlet control mechanism. The control assembly 50 can adjust the speed of liquid injection from the liquid inlet 110 by controlling the opening and closing degree of the first valve.

In some embodiments, the liquid inlet 110 may be connected to a spray head, and a plurality of through holes may be provided on the liquid spray head. Liquid may be sprayed into the liquid storage tank 10 through the through holes of the spray head. Several through holes may be divided into several injection areas, for example, a first injection area, a second injection area, a third injection area, etc. Each spray area points to a different direction, so that the liquid sprayed from different spray areas can flow in different directions. In some embodiments, the several through holes of each spray area may have the same or different opening shapes.

In some embodiments, the control assembly 50 can control the opening or closing of the spray area to allow liquid to be sprayed in a desired direction. For example, the injection head is provided with an injection main pipe and a number of injection branch pipes equal to the number of injection areas. The injection main pipe is connected with the liquid inlet 110. The injection branch pipe is connected with the injection main pipe. A second valve is provided at the connection between the injection branch pipe and the injection main pipe. Several through holes in the same injection area are connected to one injection branch pipe. The control component 50 can control the opening and closing of the second valve, thereby controlling the liquid to be ejected from a desired ejection area, and thereby controlling the ejection direction of the liquid.

In some embodiments, the number of liquid inlets 110 may be one, and the number of ejection heads may be one. According to the aforementioned embodiments, the control assembly 50 can control the opening or closing of a specific spray area on the spray head, thereby causing the liquid to be sprayed in a desired direction.

In some embodiments, the number of the liquid inlet 110 may be one, and the liquid inlet 110 may be provided with multiple spray heads. Multiple spray heads on each liquid inlet 110 can be arranged in a specific manner. For example, a certain liquid inlet 110 is provided on a longer side wall of the liquid storage tank 10 . The plurality of spray heads on the liquid inlet 110 can be arranged along the length direction of the longer side wall of the liquid storage tank 10 . In another example, multiple spray heads may be arranged in a circular array. In some embodiments, the control assembly 50 can control one or more liquid ejection heads to eject liquid to control the ejection direction of the liquid. For example, the plurality of injection heads may be divided into a first group of injection heads and a second group of injection heads, and the control assembly 50 may control the injection mode of the first group of injection heads and/or the second group of injection heads. For example, only the first group of ejection heads ejects liquid, while the second group of ejection heads stops ejecting liquid.

In some embodiments, the number of liquid inlets 110 may be multiple, and the multiple liquid inlets 110 may be disposed at different positions on the inner wall of the liquid storage tank 10 . Each liquid inlet 110 is connected to a liquid ejection head. The control assembly 50 can control one or more liquid ejection heads to eject liquid to control the ejection direction of the liquid. For example, the communication port between each liquid inlet 110 and the spray head is provided with a third valve, and the control assembly 50 can control the opening and closing of the third valve to control the liquid to be sprayed from the desired spray head. In some application scenarios, when the liquid temperature at a certain location in the liquid storage tank 10 is significantly different from the liquid at other locations, the control component 50 can control the injector head disposed at or near the location to inject liquid. The liquid ejected from the spray head can stir the nearby liquid, so that the temperature of the liquid in the liquid storage tank 10 tends to be uniform.

In some embodiments, the shape and size of each spray head, as well as the number of through holes provided on the spray head and the opening shape of the through holes may be the same or different.

In some embodiments, the structure and shape of the liquid storage tank 10 can be improved to make it easier for the liquid to collide with the inner wall of the liquid storage tank 10 . The impact can make the liquid flow path more chaotic and stir more fully, increasing the temperature exchange of the liquid at more locations in the liquid storage tank 10 , and ultimately making the temperature of the liquid in the liquid storage tank 10 tend to be uniform.

In some embodiments, the number of corners of the interior contour of reservoir 10 may be increased. The angle may refer to the angle formed between the two inner walls of the liquid storage tank 10 . For example, the angle formed by the two first side walls 102 and the second side wall 103 of the liquid storage tank 10 may be called a corner. For another example, the angle formed by a first side wall 102 and the bottom wall of the liquid storage tank 10 may also be called a corner. In some embodiments, the inner contour shape of the liquid storage tank 10 may be set as a polygonal prism to increase the number of corners of the inner contour of the liquid storage tank 10 . In some cases, when the liquid flows to the corner of the liquid storage tank 10 , the liquid will collide with the inner wall of the corner, thereby stirring the liquid in the liquid storage tank 10 . The greater the number of corners of the inner contour of the liquid storage tank 10, the more collisions the liquid will have with the inner wall of the liquid storage tank 10, resulting in a larger amount of liquid being stirred and a better stirring effect.

In some embodiments, a guide may be provided on the inner wall of the liquid storage tank 10 near the liquid inlet 110 . In some cases, when the liquid is ejected from the liquid inlet 110, the guide member can block the liquid, causing the liquid to collide with the guide member, thereby causing the liquid around the guide member to agitate, thereby improving the liquid stirring effect. In addition, the guide member can also guide the flow direction of the liquid when it is sprayed out.

In some embodiments, the guide may include several flexible tentacles. Flexible tentacles may refer to elastic tentacle-like structures.

8 to 10 exemplarily show the specific structure of the liquid inlet and outlet assembly 20. As shown in FIGS. 8 to 10 , in some embodiments, the liquid inlet and outlet assembly 20 may further include a baffle 240 , and the baffle 240 is disposed on the side wall of the liquid storage tank 10 . The baffle 240 is provided with a liquid inlet 110 and a liquid outlet opening 242 corresponding to the liquid outlet 120 . The liquid outlet pipeline 220 can be connected to the liquid outlet 120 through the liquid outlet opening 242, and the liquid inlet pipeline 210 can be connected to the liquid inlet 110.

In some embodiments, the baffle 240 can be used to isolate other components of the liquid inlet and outlet assembly 20 from the inside of the liquid storage tank 10 to prevent liquid in the liquid storage tank 10 from entering the liquid inlet and outlet assembly 20 . The baffle 240 is embedded in the first side wall 102 of the liquid storage tank 10 , and the plane where the baffle 240 is located is flush with the inner surface of the first side wall 102 . The baffle 240 is provided with a liquid inlet 110 and a liquid outlet 120. Liquid can enter the liquid storage tank 10 through the liquid inlet 110 or flow out of the liquid storage tank 10 through the liquid outlet 120. In another example, the baffle 240 of the liquid inlet and outlet assembly 20 may be equivalent to the installation housing 130 in the embodiment shown in FIG. 11 . The difference from the example of FIG. 5 is that the baffle 240 in FIG. 11 protrudes toward the inside of the liquid storage tank 10 to form a receiving space inside the side wall of the liquid storage tank 10 , and other components of the liquid inlet and outlet assembly 20 can be disposed This accommodation space is isolated from the liquid in the liquid storage tank 10 by the baffle 240 . The liquid in the liquid storage tank 10 can flow out through the liquid outlet 120, but due to the existence of the baffle 240, it cannot penetrate into the accommodation space.

In some embodiments, the baffle 240 may be fixedly connected to the inner wall of the liquid storage tank 10 . Exemplary fixed connection methods may include bonding, screw connection, welding, etc. In some embodiments, in order to further improve the waterproof performance, a waterproof material may be provided at the connection between the baffle 240 and the liquid storage tank 10 , and an exemplary waterproof material may include waterproof glue.

In some embodiments, when the liquid inlet and outlet assembly 20 is applied in a liquid storage container, for example, in the liquid storage tank 10 , the size of the baffle 240 may be determined according to the size of the liquid storage tank 10 . As shown in FIG. 5 , in some embodiments, the baffle 240 can be embedded on the side wall of the liquid storage tank 10 and flush with the inner surface of the side wall, as a part of the first side wall 102 of the liquid storage tank 10 .

In some embodiments, the baffle 240 may not be a necessary component of the liquid inlet and outlet assembly, and other components of the liquid inlet and outlet assembly 20 may be isolated from the inside of the liquid storage tank 10 by other means. For example, other components of the liquid inlet and outlet assembly 20 can be disposed outside the side wall of the liquid storage tank 10 , and the liquid inlet 110 is directly opened on the side wall of the liquid storage tank 10 (for example, the first side wall 102 ). and the liquid outlet 120, which are sealedly connected to the liquid inlet 110 and the liquid outlet 120 by the liquid inlet pipe 210 and the liquid outlet pipe 220. In this embodiment, the first side wall 102 can block the liquid in the liquid storage tank 10, so that there is no need to provide a separate baffle 240.

As shown in FIG. 8 , in some embodiments, the liquid inlet and outlet assembly 20 may further include a filter assembly 250 . The filter assembly 250 may include a filter screen 251 and a filter support 252 . The filter support 252 is provided with a liquid outlet 120. The filter support 252 can be disposed on the baffle 240. The filter support 252 can support the filter screen 251 so that the filter screen 251 is located between the liquid outlet 120 and the liquid outlet opening 242. . In some application scenarios, impurities may be attached to the food material or the vacuum bag containing the food material. When the impurities enter the liquid outlet pipe 220 through the liquid outlet 120 , they may cause blockage of the liquid outlet pipe 220 . In this embodiment, by providing an additional filter 251 at the liquid outlet opening 242 and the liquid outlet 120 , impurities can be effectively filtered and impurities can be prevented from clogging the liquid outlet pipe 220 from the liquid outlet 120 .

For convenience of explanation, this description will take the baffle 240 in the embodiment of FIG. 8 as an example to describe the filter assembly 250 and the cooperation between the filter assembly 250 and the baffle 240 . In some embodiments, the baffle 240 is provided with a mounting groove 241 , and the depth direction of the mounting groove 241 is parallel to the thickness direction of the baffle 240 . Two liquid outlet openings 242 are provided at the bottom of the installation groove 241 . The liquid outlet openings 242 penetrate the bottom wall of the installation groove 241 along the thickness direction of the baffle 240 . The filter support member 252 has a plate-like structure, and two liquid outlets 120 are provided on the filter support member 252 . The filter screen 251 can be installed on the filter support 252 to cover the two liquid outlets 120 . The outer contour of the filter support 252 is adapted to the inner contour of the mounting groove 241 . When the filter support 252 is mated with the installation groove 241, the filter screen 251 is located between the liquid outlet 120 and the liquid outlet opening 242.

In some embodiments, the filter assembly 250 and the baffle 240 may be detachably connected to facilitate replacement of the filter screen 251. Exemplary detachable connection methods may include bonding, screw connection, magnetic connection, etc. As shown in FIG. 8 , in some specific embodiments, the lower side wall of the installation groove 241 is provided with a clamping groove 243 . The upper side wall of the installation slot 241 is provided with a through slot 244. The through slot 244 penetrates the bottom wall of the installation slot 241 along the thickness direction of the file. The upper side wall of the through slot 244 is provided with a buckle plate 245. The bottom wall of the installation groove 241 is provided with a clamping hole 248, and the clamping hole 248 is connected with the through slot 244. The lower side wall of the filter support member 252 is provided with a first buckle 246 that is adapted to the buckle slot 243 . The upper side wall of the filter support member 252 is provided with a second buckle 247. The second buckle 247 is bent and has a certain elasticity, and can be elastically deformed under the action of external force. When the filter support 252 and the installation groove 241 need to be mated, the first buckle 246 can be extended into the buckle 243, and then the second buckle 247 can be pressed to pass through the buckle hole 248. When the second buckle 247 passes through the buckle hole 248, the second buckle 247 is released, allowing it to recover its deformation and abut against the side of the buckle plate 245 away from the filter support member 252.

In some embodiments, in order to improve the filtration effect, a filter 251 may also be provided between the second connection port 204 and the liquid outlet opening 242 . In other embodiments, the filter 251 may be provided at the second pair of interfaces 202 .

In some embodiments, the number of filters 251 may be the same as the number of liquid outlets 120 . For example, in the embodiment shown in FIG. 8 , the number of liquid outlets 120 of the filter support member 252 is two, and the number of filter screens 251 is two. Each liquid outlet 120 is individually covered by a filter 251 . In other embodiments, one filter 251 can cover multiple liquid outlets 120 at the same time.

In some embodiments, the liquid inlet and outlet assembly 20 may include a first pair of interfaces 201 and a second pair of interfaces 202 . As described in the previous embodiments, the liquid outlet pipeline 220 may be connected to the second docking port 202 and the liquid outlet 120 respectively. The liquid inlet pipeline 210 can be connected with the first pair of interfaces 201 and the liquid inlet 110 respectively. The liquid in the liquid storage tank 10 can enter the liquid outlet pipe 220 from the liquid outlet 120 , and then flow out from the second pairing interface 202 via the liquid outlet pipe 220 . In addition, the liquid can enter the liquid inlet pipe 210 through the first pair of interfaces 201, and then flow into the inside of the liquid storage tank 10 from the liquid inlet 110 through the liquid inlet pipe 210.
