[0117] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0118] like Figures 1 to 6As shown, a cooking appliance is provided according to a first aspect of the present disclosure, comprising: a pot body assembly 100 having a cooking cavity 101; and a spray assembly 200 for conveying a fluid medium into the cooking cavity 101, wherein the spray direction of the spray assembly 200 is adjustable between a first direction and a second direction; wherein the first direction is toward the inner top wall of the pot body assembly 100, and the second direction is toward the inner bottom wall 103 of the pot body assembly 100.

[0119] The cooking appliance provided in this embodiment includes a pot body assembly 100 and a spray assembly 200. The pot body assembly 100 forms a cooking cavity 101, which can accommodate the food to be cooked, providing space for cooking. The spray assembly 200 can be used to deliver a fluid medium into the cooking cavity 101, thereby improving the convenience of injecting liquid or gas into the cooking cavity 101 during cooking and enhancing the ease of use of the cooking appliance. Furthermore, the spray direction of the spray assembly 200 can be adjusted between a first direction and a second direction, allowing the spray direction to be controlled within a certain range, providing high flexibility and controllability. Correspondingly, by adjusting the spray direction of the spray assembly 200, the fluid medium can be sprayed into different areas within the cooking cavity 101, increasing the diversity of fluid medium injection methods for the cooking appliance. This is beneficial for improving the adaptability of the cooking appliance to different cooking processes, ensuring the cooking effect of the cooking appliance, and saving the amount of spray assembly 200 used, which is conducive to ensuring the miniaturization level of the cooking appliance.

[0120] It should be noted that the aforementioned first direction toward the inner top wall of the pot assembly 100 refers to a direction originating from the spray assembly 200 and intersecting with the inner top wall of the pot assembly. This intersection can be perpendicular or non-perpendicular. Similarly, the aforementioned second direction toward the inner bottom wall 103 of the pot assembly 100 refers to a direction originating from the spray assembly 200 and intersecting with the inner bottom wall 103 of the pot assembly. This intersection can be perpendicular or non-perpendicular. The fact that the spray direction of the spray assembly 200 can be adjusted between the first and second directions means that the spray assembly 200 has multiple feasible spray directions. These multiple feasible spray directions are all within the angle range between the first and second directions and are not identical to each other. During operation, the spray direction of the spray assembly 200 can be at least one of the multiple feasible spray directions and can be switched between them. The aforementioned angle range includes both the first and second directions.

[0121] For example, such as Figure 2 As shown, some feasible spray directions of the spray assembly 200 may include, but are not limited to, those shown. Figure 2The directions indicated by the dashed lines F1 and / or F2 and / or F3 with arrows are as follows: F1 schematically represents a direction perpendicular to the inner wall of the pot assembly 100; F2 schematically represents a direction perpendicular to the inner bottom wall of the pot assembly; and F3 schematically represents a direction inclined to the height of the cooking appliance and away from the inner top wall of the pot assembly. It is understood that in practical applications, the feasible spray directions of the spray assembly 200 are not limited to the directions indicated by the aforementioned dashed lines F1 and / or F2 and / or F3 with arrows. For example, they may also include directions perpendicular to the inner top wall of the pot assembly 100, and / or directions inclined to the height of the cooking appliance and away from the inner bottom wall of the pot assembly, etc.

[0122] It is understood that the inner wall of the pot body assembly 100 can form the aforementioned cooking cavity 101, and the inner wall of the pot body assembly 100 can include an inner top wall, the aforementioned inner side wall 102, and the aforementioned inner bottom wall 103. The aforementioned inner bottom wall 103 refers to the portion of the inner wall of the pot body assembly 100 opposite to the pot opening, and the aforementioned inner top wall refers to the portion of the inner wall of the pot body assembly 100 covering the pot opening. The aforementioned inner top wall can be located in the pot lid portion 120 of the pot body assembly 100. The aforementioned inner side wall 102 is the portion of the inner wall of the pot body assembly 100 located between the aforementioned inner top wall and inner bottom wall 103. The aforementioned inner bottom wall 103 and the aforementioned inner top wall are arranged opposite each other along the height direction of the cooking appliance, and the position height of the aforementioned inner bottom wall is lower than the position height of the aforementioned inner top wall. Accordingly, when the spray direction of the spray assembly 200 is directed toward the inner wall 102 of the pot assembly 100, the spray direction of the spray assembly 200 has a high degree of horizontality, that is, the spray direction of the spray assembly 200 is perpendicular or approximately perpendicular to the height direction of the cooking appliance; when the spray direction of the spray assembly 200 is the aforementioned first direction or second direction, the spray direction of the spray assembly 200 has a high degree of verticality, that is, the spray direction of the spray assembly 200 is parallel or approximately parallel to the height direction of the cooking appliance.

[0123] It should be noted that the first direction can be towards the inner top wall of the pot body assembly 100, and the second direction can be towards the inner bottom wall 103 of the pot body assembly 100, so as to expand the spraying range of the spraying assembly 200 in actual application, making it easier for the spraying assembly 200 to spray fluid medium to different positions in the cooking cavity 101, which is conducive to further improving the adaptability of the cooking appliance to different cooking processes and providing a more reliable guarantee for the cooking effect of the cooking appliance.

[0124] It is understood that when the first direction is toward the inner top wall of the pot assembly 100 and the second direction is toward the inner bottom wall 103 of the pot assembly 100, the multiple feasible spraying directions of the spraying assembly 200 can be arranged around the horizontal direction, and the multiple spraying directions are distributed around the aforementioned horizontal direction within the angle range between the first direction and the second direction, the aforementioned angle range including the first direction and the second direction.

[0125] It is understood that the aforementioned fluid medium can be, but is not limited to, liquid or gas. The aforementioned liquid can be, but is not limited to, water, and the aforementioned gas can be, but is not limited to, air. Taking air as an example, the cooking appliance can use the spray component 200 to deliver gas into the cooking chamber 101 during the cooking process, so as to use the gas to disturb the food in the cooking chamber 101, thereby improving the cooking effect. Alternatively, after cooking, it can deliver lower temperature gas into the cooking chamber 101 to reduce the temperature in the cooking chamber 101, making it easier for the user to open the lid and take out the food.

[0126] To facilitate understanding of some feasible uses of the cooking appliances provided in this disclosure during actual cooking, several application scenarios of different spray directions of the spray assembly 200 are illustrated herein by way of example.

[0127] When the spraying direction of the spraying assembly 200 is perpendicular or approximately perpendicular to the inner wall 102 of the pot assembly 100, the spraying assembly 200 can easily add liquid into the cooking cavity 101 during the cooking process. The liquid can be, but is not limited to, water or broth. Accordingly, when the cooking process reaches a certain stage or the pot temperature reaches a certain level, the spraying assembly 200 can spray liquid onto the inner wall 102 of the pot assembly 200, thereby avoiding direct spraying of low-temperature water onto the food in the bottom area of ​​the cooking cavity 101. The water sprayed by the spraying assembly 200 can easily come into contact with the inner wall 102 first and slide down the inner wall 102 towards the inner bottom wall 103 under the action of gravity. During the sliding process, the water can absorb the heat of the pot assembly 100 through the inner wall 102, so that it has a higher temperature when it comes into contact with the food in the bottom area of ​​the cooking cavity 101, which is beneficial to improving the taste of the food after cooking.

[0128] When the spray direction of the spray assembly 200 is perpendicular or substantially perpendicular to the inner bottom wall 102 of the pot assembly 100, the spray assembly 200 can easily add liquid or gas into the cooking cavity during the cooking process. The liquid can be, but is not limited to, water or broth, and the gas can be, but is not limited to, air. Accordingly, when the cooking process reaches a certain stage or the pot temperature reaches a certain level, the spray assembly 200 can spray liquid onto the inner bottom wall 103 of the pot assembly 200 so that the water sprayed by the spray assembly 200 can disturb the broth used for cooking dumplings or noodles. It is understood that during the cooking process of pasta, the water can be water at a lower temperature, which helps to prevent the pasta from gelatinizing and ensures the taste of the cooked food.

[0129] When the spray direction of the spray assembly 200 is perpendicular or approximately perpendicular to the inner top wall 102 of the pot assembly 100, or when the spray direction is inclined to the height direction of the cooking appliance and away from the inner bottom wall of the pot assembly, the spray assembly 200 can easily inject gas into the cooking cavity during the steaming process. The liquid mentioned above can be water vapor to provide heat and moisture for the steaming of the food. Alternatively, after cooking is completed, the spray assembly 200 can inject low-temperature air into the cooking cavity 101 so that the low-temperature air preferentially cools the higher areas in the cooking cavity 101. Then, the low-temperature air can flow downward in the cooking cavity 101 to increase the temperature drop rate in the cooking cavity 101, which is beneficial to lower the temperature of the food and makes it easier for the user to quickly open the lid and take out the food after cooking.

[0130] When the spray direction of the spray assembly 200 is inclined to the height direction of the cooking appliance and away from the inner bottom wall of the pot assembly, the spray assembly 200 can easily add liquid into the cooking cavity during the steaming of low-sugar rice. The liquid can be water. Accordingly, the water output by the spray assembly 200 can be sprayed onto the rice to be steamed to rinse the rice, thereby reducing the sugar content of the rice. In this case, the output pressure of the spray assembly 200 can be adjusted, so that water can be sprayed onto different parts of the rice to enhance the sugar rinsing effect. It is understood that the cooking appliance may also include a low-sugar pot, which is detachably installed in the cooking cavity for holding the rice to be steamed. The aforementioned low-sugar pot can be equipped with a liquid baffle. When the spray assembly 200 outputs liquid in the direction that is inclined to the height of the cooking appliance and away from the inner bottom wall of the pot assembly, the liquid baffle can be used to receive the liquid output by the spray assembly 200 and guide the liquid into the pot space, so that the fluid medium can be sprayed more evenly on the rice to be steamed in the pot space, while reducing the impact of the liquid flow on the rice and ensuring the flatness of the rice surface.

[0131] It is understood that the above examples of several different spraying directions of the spray assembly 200 are only for illustrating some feasible ways of using the cooking appliance provided in this disclosure. In practical applications, the spraying direction of the spray assembly 200 can also be adjusted in combination with other different usage scenarios or cooking processes, which will not be listed here.

[0132] It should be noted that, in practical applications, the cooking appliances provided in this disclosure can be used as, but are not limited to, electric pressure cookers, electric steamers, electric saucepans, electric frying pans, multi-functional cookers, and other cooking appliances.

[0133] Taking the aforementioned cooking appliance as a multi-functional pot that combines stir-frying, boiling, and steaming functions as an example, the ingredients to be cooked can be placed inside the cooking cavity 101, and the fluid medium can be water. When stir-frying the ingredients, the spray direction of the spray component 200 can be adjusted to face the inner wall 102 of the pot body component 100. When the stir-frying process reaches a certain stage or the pot body temperature reaches a certain level, the spray component 200 can spray water towards the inner wall 102 of the pot body component 100, thereby avoiding direct spraying of low-temperature water onto the ingredients at the bottom of the cooking cavity 101. This also allows the water sprayed by the spray component 200 to easily contact the inner wall 102 first and slide down the inner wall 102 towards the inner bottom wall 103 under the action of gravity. Water can absorb heat from the pot assembly 100 through the aforementioned inner wall 102, so that it has a higher temperature when it comes into contact with the food in the bottom area of ​​the cooking cavity 101, which is beneficial to improving the taste of the food after stir-frying. When cooking the food, such as dumplings or noodles, the spray direction of the spray assembly 200 can be adjusted to face the inner bottom wall 103 of the pot assembly 100. When the cooking process reaches a certain level or the pot temperature reaches a certain level, the spray assembly 200 can spray water towards the inner bottom wall 103 of the pot assembly 100 so that the water sprayed by the spray assembly 200 can disturb the soup used to cook dumplings or noodles. It can be understood that during the cooking process of noodles, the aforementioned water can be water at a lower temperature, which is beneficial to avoid the noodles from becoming gelatinized and to ensure the taste of the food after cooking. Other application scenarios of cooking appliances and the spray direction of the spray component 200 in other cooking processes will not be listed here. However, it is easy to understand that the cooking appliances provided in this embodiment, based on the aforementioned settings, can improve the adaptability of the liquid injection method of the cooking appliances to different cooking processes and enhance the cooking effect of the cooking appliances.

[0134] Understandably, in practical applications, cooking appliances can also utilize the spray assembly 200 for operations requiring the participation of a fluid medium, such as depressurizing the cooking chamber 101, adding fluid medium for cooking ingredients, and cleaning the pot body assembly 100, thereby further improving the ease of use of cooking appliances.

[0135] It is understandable that, in practical applications, there can be multiple ways to achieve adjustable spray direction of the spray assembly 200. For example, the spray assembly 200 can have spray nozzles for outputting fluid media. Correspondingly, the spray direction of the spray assembly 200 can be adjusted by making the position of the spray nozzles movable. Alternatively, the spray assembly 200 can have multiple spray nozzles facing different directions, and the opening and closing states of the nozzles with different directions can be controlled independently, thereby achieving spraying in different directions. In practical applications, the method for achieving adjustable spray direction of the spray assembly 200 can be selected based on actual needs, and no further limitations are imposed here.

[0136] In some feasible examples, the aforementioned spray assembly 200 can be disposed on the inner top wall of the pot body assembly 100, which is beneficial to improve the spraying efficiency of the spray assembly 200 and the coverage of the cooking cavity 101; for example, the aforementioned spray assembly 200 can be disposed in the middle region of the inner top wall of the pot body assembly 100.

[0137] like Figures 1 to 6 As shown, in some examples, the spray assembly 200 includes: a spray head 220 having a first spray port 2201 and a second spray port 2202, the first spray port 2201 being open in a third direction and the second spray port 2202 being open in a fourth direction, both the third and fourth directions being located between the first and second directions, and the third direction being different from the fourth direction; and a pumping section 230 connected to the spray head 220; wherein the spray head 220 is movable relative to the pumping section 230 so that the output end of the pumping section 230 is connected to the first spray port 2201 or the second spray port 2202.

[0138] In this technical solution, the aforementioned spray assembly 200 may include a spray head 220 and a pumping unit 230. The pumping unit 230 is connected to the spray head 220 and provides power for the flow of fluid medium to the spray head 220. Accordingly, the fluid medium can flow through the spray head 220 to the cooking chamber 101, thereby injecting fluid medium into the cooking chamber 101. The spray head 220 has a first spray port 2201 connected in the aforementioned third direction and a second spray port 2202 connected in the aforementioned fourth direction. Accordingly, the spray head 220 can be movable relative to the pumping unit 230, allowing the output end of the pumping unit 230 to be connected to the first spray port 2202. The spray nozzle 2201 or the second spray nozzle 2202, that is, in practical applications, can be manipulated by moving the spray head 220 relative to the pumping unit 230 to make the fluid medium output by the pumping unit 230 flow to the first spray nozzle 2201 or the second spray nozzle 2202. Correspondingly, the fluid medium can flow to the cooking chamber 101 in a third or fourth direction, so that the fluid medium can fall to different positions in the cooking chamber 101. This can improve the diversity of fluid medium injection methods of the cooking appliance, which is conducive to improving the adaptability of the cooking appliance to different cooking processes, ensuring the cooking effect of the cooking appliance, and saving the number of spray heads 220 used, which is conducive to ensuring the miniaturization level of the cooking appliance.

[0139] It is understood that, in practical applications, the input end of the pumping unit 230 can be connected to a fluid medium supply device so that the pumping unit 230 can access the fluid medium. For example, the aforementioned fluid medium supply device can be an external device for discharging fluid medium from a cooking appliance, such as a faucet.

[0140] like Figures 1 to 6 As shown, in some feasible examples, the spray assembly 200 further includes a liquid storage section 210, forming a liquid storage chamber 2101; wherein, the pumping section 230 is connected between the liquid storage section 210 and the spray head 220. It is understood that the aforementioned fluid medium can be a liquid, and the aforementioned liquid storage chamber 2101 is used to contain the aforementioned liquid, thereby improving the convenience of liquid dispensing from the cooking appliance and enhancing the ease of use of the cooking appliance. The aforementioned liquid storage section 210 may be provided with a liquid inlet, which can be used to connect to the aforementioned fluid medium output device.

[0141] like Figures 1 to 6 As shown, in some examples, the third direction is a direction perpendicular to the inner wall 102 of the pot body assembly 100, or a direction perpendicular to the inner bottom wall 103 of the pot body assembly 100, or a direction perpendicular to the inner top wall of the pot body assembly 100, or a direction inclined to the height direction of the cooking appliance and away from the inner top wall of the pot body assembly 100, or a direction inclined to the height direction of the cooking appliance and away from the inner bottom wall 103 of the pot body assembly 100.

[0142] The fourth direction is a direction perpendicular to the inner wall 102 of the pot body assembly 100, or a direction perpendicular to the inner bottom wall 103 of the pot body assembly 100, or a direction perpendicular to the inner top wall of the pot body assembly 100, or a direction inclined to the height direction of the cooking appliance and away from the inner top wall of the pot body assembly 100, or a direction inclined to the height direction of the cooking appliance and away from the inner bottom wall 103 of the pot body assembly 100.

[0143] In this technical solution, the guiding direction of the aforementioned first spray nozzle 2201 can be one of the following: a direction perpendicular to the inner wall 102 of the pot assembly 100; a direction perpendicular to the inner bottom wall 103 of the pot assembly 100; a direction perpendicular to the inner top wall of the pot assembly 100; a direction inclined to the height direction of the cooking appliance and away from the inner top wall of the pot assembly 100; and a direction inclined to the height direction of the cooking appliance and away from the inner bottom wall 103 of the pot assembly 100. It can be understood that, in conjunction with the foregoing, when the third direction is perpendicular to the inner wall 102 of the pot assembly 100, the spray assembly 200 is suitable for adding liquid into the cooking cavity during the stir-frying process to ensure the texture of the food after stir-frying; when the third direction is perpendicular to the inner bottom wall 103 of the pot assembly 100... In some cases, the spray assembly is adapted to inject liquid or gas into the cooking cavity 101 during the cooking process to agitate the food and the cooking liquid; when the third direction is perpendicular to the inner top wall of the pot assembly 100, or inclined to the height of the cooking appliance and away from the inner bottom wall 103 of the pot assembly 100, the spray assembly 200 is adapted to output steam into the cooking cavity 101 during the steaming process, or output low-temperature air into the cooking cavity 101 after cooking, so as to improve the steaming efficiency of the food or accelerate the cooling of the food; when the third direction is inclined to the height of the cooking appliance and away from the inner top wall of the pot assembly 100, the spray assembly 200 is adapted to spray liquid into the cooking cavity 101 during the steaming of low-sugar rice to rinse the rice and reduce the sugar content of the rice.

[0144] In this technical solution, the guiding direction of the second spray nozzle 2202 can be one of the following: perpendicular to the inner wall 102 of the pot assembly 100, perpendicular to the inner bottom wall 103 of the pot assembly 100, perpendicular to the inner top wall of the pot assembly 100, inclined to the height direction of the cooking appliance and away from the inner top wall of the pot assembly 100, and inclined to the height direction of the cooking appliance and away from the inner bottom wall 103 of the pot assembly 100. It can be understood that, in conjunction with the foregoing, when the fourth direction is perpendicular to the inner wall 102 of the pot assembly 100, the spray assembly 200 is suitable for adding liquid into the cooking cavity during the stir-frying process to ensure the texture of the food after stir-frying; when the fourth direction is perpendicular to the inner bottom wall 103 of the pot assembly 100... The spray assembly is adapted to inject liquid or gas into the cooking chamber 101 during the cooking process to agitate the food and the cooking liquid. When the fourth direction is perpendicular to the inner top wall of the pot assembly 100, or inclined to the height of the cooking appliance and away from the inner bottom wall 103 of the pot assembly 100, the spray assembly 200 is adapted to output steam into the cooking chamber 101 during the steaming process, or output low-temperature air into the cooking chamber 101 after cooking, so as to improve the steaming efficiency of the food or accelerate the cooling of the food. When the fourth direction is inclined to the height of the cooking appliance and away from the inner top wall of the pot assembly 100, the spray assembly 200 is adapted to spray liquid into the cooking chamber 101 during the steaming of low-sugar rice to rinse the rice and reduce the sugar content of the rice.

[0145] It is understood that the third and fourth directions can be two different directions among the following: the direction perpendicular to the inner wall 102 of the pot assembly 100, the direction perpendicular to the inner bottom wall 103 of the pot assembly 100, the direction perpendicular to the inner top wall of the pot assembly 100, the direction inclined to the height direction of the cooking utensil and away from the inner top wall of the pot assembly 100, and the direction inclined to the height direction of the cooking utensil and away from the inner bottom wall 103 of the pot assembly 100. That is, the third and fourth directions can be any combination of any two of the aforementioned five directions. In practical applications, the specific directions of the third and fourth directions can be selected according to actual needs, and no further restrictions are imposed here.

[0146] like Figures 2 to 6As shown, in some examples, the output end of the pumping section 230 is located on the inner wall of the pot assembly 100, and the spray head 220 is rotatably disposed on the inner wall of the pot assembly 100 and covers the output end of the pumping section 230. The spray head 220 has a first channel 2204 and a second channel 2205 formed on the side facing the output end of the pumping section 230. The first channel 2204 and the second channel 2205 are arranged at intervals along the rotation direction of the spray head 220. The first channel 2204 is connected to the first spray port 2201, and the second channel 2205 is connected to the second spray port 2202.

[0147] In this technical solution, the output end of the aforementioned pumping section 230 and the aforementioned spray head 220 can be disposed on the inner wall of the pot assembly 100. Correspondingly, the spray head 220 can be disposed covering the output end of the pumping section 230, so that the spray head 220 can be connected to the fluid medium through the pumping section 230. The side of the spray head 220 facing the output end of the pumping section 230 can be formed with a first channel 2204 and a second channel 2205 respectively connected to the first spray port 2201 and the second spray port 2202. The spray head 220 can be relatively The spray head 220 rotates on the inner wall of the pot body assembly 100, and the aforementioned first channel 2204 and second channel 2205 are arranged at intervals along the rotation direction of the spray head 220. Thus, by rotating the spray head 220, the first channel 2204 or the second channel 2205 can be connected to the output end of the pumping unit 230, so as to guide the fluid medium to the corresponding spray nozzle. Based on the aforementioned arrangement, the range of motion of the spray head 220 can be further limited, the space occupied by the spray head 220 can be reduced, and the structural compactness and miniaturization level of the cooking appliance can be improved.

[0148] It is understood that the output end of the aforementioned pumping unit 230 refers to the end at which the pumping unit 230 outputs the fluid medium.

[0149] Understandably, in practical applications, the spray head 220 can be manually rotated by the user. Accordingly, the periphery of the spray head 220 can be formed with structures that facilitate manual operation by the user, such as raised structures, recessed structures, or anti-slip textures. Alternatively, a drive unit 240 can be configured for the aforementioned spray head 220 to drive the spray head 220 to rotate, thereby improving the ease of use of the spray head 220.

[0150] like Figures 2 to 6As shown, in some examples, the nozzle 220 also forms a third spray port 2202, the third spray port 2203 is open along a fifth direction, the fifth direction is located between the first direction and the second direction and is different from the aforementioned third direction and the aforementioned fourth direction, the nozzle 220 also forms a third channel 2206 on the side of the nozzle 220 facing the output end of the pumping unit 230, the third channel 2206 is connected to the third spray port 2203, and the first channel 2204, the second channel 2205 and the third channel 2206 are arranged at intervals along the rotation direction of the nozzle 220.

[0151] In this technical solution, the spray head 220 facing the output end of the pumping unit 230 can be formed with a first channel 2204, a second channel 2205, and a third channel 2206 respectively connected to the first spray port 2201, the second spray port 2202, and the third spray port 2203. The spray head 220 can rotate relative to the inner wall of the pot assembly 100, and the aforementioned first channel 2204, second channel 2205, and third channel 2206 are arranged at intervals along the rotation direction of the spray head 220. Thus, by rotating the spray head 220, the first channel 2204, the second channel 2205, or the third channel 2206 can be connected to the output end of the pumping unit 230 to guide the fluid medium to the corresponding spray port. Based on the aforementioned arrangement, the range of motion of the spray head 220 can be further limited, the space occupied by the spray head 220 can be reduced, and the structural compactness and miniaturization level of the cooking appliance can be improved. Furthermore, based on the aforementioned configuration, the spray assembly 200 can inject fluid medium into the cooking chamber through the third spray port 2203, thereby further improving the diversity of fluid medium injection methods for the cooking appliance, which is conducive to improving the adaptability of the cooking appliance to different cooking processes, ensuring the cooking effect of the cooking appliance, and saving the number of spray heads 220 used, which is conducive to ensuring the miniaturization level of the cooking appliance.

[0152] It is understood that the aforementioned fifth direction can be one of the following: a direction perpendicular to the inner wall 102 of the pot assembly 100; a direction perpendicular to the inner bottom wall 103 of the pot assembly 100; a direction perpendicular to the inner top wall of the pot assembly 100; a direction inclined to the height direction of the cooking utensil and away from the inner top wall of the pot assembly 100; and a direction inclined to the height direction of the cooking utensil and away from the inner bottom wall 103 of the pot assembly 100. It is understood that, in conjunction with the foregoing, when the fifth direction is perpendicular to the inner wall 102 of the pot assembly 100, the spray assembly 200 is suitable for adding liquid into the cooking cavity during the stir-frying process to ensure the texture of the food after stir-frying; when the fifth direction is perpendicular to the inner bottom wall 103 of the pot assembly 100, the spray assembly 200... The components are adapted to inject liquid or gas into the cooking cavity 101 during the cooking process to agitate the food and the cooking liquid; when the fifth direction is perpendicular to the inner top wall of the pot assembly 100, or inclined to the height of the cooking appliance and away from the inner bottom wall 103 of the pot assembly 100, the spray assembly 200 is adapted to output water vapor into the cooking cavity 101 during the steaming process, or output low-temperature air into the cooking cavity 101 after cooking, so as to improve the steaming efficiency of the food or accelerate the cooling of the food; when the fifth direction is inclined to the height of the cooking appliance and away from the inner top wall of the pot assembly 100, the spray assembly 200 is adapted to spray liquid into the cooking cavity 101 during the steaming of low-sugar rice to rinse the rice and reduce the sugar content of the rice. The aforementioned third, fourth, and fifth directions can be three different directions: a direction perpendicular to the inner wall 102 of the pot assembly 100; a direction perpendicular to the inner bottom wall 103 of the pot assembly 100; a direction perpendicular to the inner top wall of the pot assembly 100; a direction inclined to the height direction of the cooking utensil and away from the inner top wall of the pot assembly 100; and a direction inclined to the height direction of the cooking utensil and away from the inner bottom wall 103 of the pot assembly 100. That is, the third and fourth directions can be any combination of three of the aforementioned five directions. In practical applications, the specific directions of the third, fourth, and fifth directions can be selected according to actual needs, and no further limitations are imposed here.

[0153] In some examples, the conduction area of ​​the inlet end of the third channel 2206 is greater than the conduction area of ​​the output end of the pumping unit 230.

[0154] In this technical solution, the conductive area of ​​the inlet end of the third channel 2206 can be set to be larger than the conductive area of ​​the output end of the pumping unit 230. Thus, during the rotation of the spray head 220, the output end of the pumping unit 230 can easily enter the distribution range of the inlet end of the third channel 2206. This facilitates the docking of the third channel 2206 with the output end of the pumping unit 230, reduces the control accuracy requirements for the rotation position of the spray head 220, and improves the operation and ease of use of the spray assembly 200.

[0155] It is understood that the liquid inlet end of the aforementioned third channel 2206 refers to the end of the third channel 2206 located at the end of the nozzle 220 facing the output end of the pumping unit 230.

[0156] In some examples, the inlet area of ​​the first channel 2204 and the second channel 2205 is greater than the outlet area of ​​the pumping unit 230.

[0157] In this technical solution, the inlet areas of the first channel 2204 and the second channel 2205 can be set to be larger than the outlet area of ​​the pumping unit 230. As a result, during the rotation of the spray head 220, the outlet of the pumping unit 230 can easily enter the distribution range of the inlet of the first channel 2204 or the second channel 2205. This facilitates the docking of the first channel 2204 and the second channel 2205 with the outlet of the pumping unit 230, reduces the control accuracy requirements for the rotation position of the spray head 220, and improves the ease of operation and use of the spray assembly 200.

[0158] It is understood that the liquid inlet end of the aforementioned first channel 2204 and second channel 2205 refers to the end of the first channel 2204 and second channel 2205 located at the output end of the nozzle 220 facing the pumping unit 230.

[0159] like Figure 3 As shown, in some examples, the spray assembly 200 further includes a drive unit 240 connected to the spray head 220 for driving the spray head 220 to rotate.

[0160] In this technical solution, the aforementioned spray assembly 200 may further include a drive unit 240 connected to the spray head 220. The drive unit 240 can be used to drive the spray head 220 to rotate. Based on the aforementioned configuration, the ease of use of the spray head 220 can be improved, and it is beneficial to improve the automation level of cooking appliances.

[0161] like Figure 3 As shown, in some examples, the drive unit 240 includes: a drive motor 241; a drive gear 242 connected to the drive motor 241; and a transmission tooth 2207 formed on the periphery of the nozzle 220, which meshes with the drive gear 242.

[0162] In this technical solution, the aforementioned drive unit 240 may include a drive motor 241 and a drive gear 242. The periphery of the aforementioned spray head 220 may be formed with transmission teeth 2207 that mesh with the aforementioned drive gear 242. Thus, the drive motor 241 can drive the spray head 220 to rotate through gear transmission, which can improve the rotational stability and reliability of the spray head 220. Compared with the direct drive method, it can reduce the performance requirements of the drive motor 241 and help improve the control accuracy of the rotational position of the spray head 220, providing a reliable guarantee for the stable adjustment of the spray direction of the spray assembly 200.

[0163] It is understandable that the aforementioned transmission gear 2207 may be integrally formed during the manufacturing process of the spray head 220, thereby reducing the reliability of the connection between the transmission gear 2207 and the spray head 220.

[0164] It is understood that there are multiple transmission teeth 2207, and these multiple transmission teeth 2207 are arranged at intervals along the rotation direction of the spray head 220.

[0165] like Figures 2 to 6 As shown, in some examples, there are multiple first spray nozzles 2201 and / or second spray nozzles 2202 and / or third spray nozzles 2203.

[0166] In this technical solution, the number of first spray nozzles 2201 and / or second spray nozzles 2202 and / or third spray nozzles 2203 can be multiple, thereby further increasing the spray volume and coverage of the spray assembly 200 in each spray direction, which is beneficial to improving the spray effect and spray efficiency of the spray assembly 200.

[0167] It is understood that multiple first spray nozzles 2201 can be connected to the same first channel 2204, thereby improving the structural compactness of the spray head 220; and / or multiple second spray nozzles 2202 can be connected to the same second channel 2205, thereby improving the structural compactness of the spray head 220; and / or multiple third spray nozzles 2201 can be connected to the same third channel 2206, thereby improving the structural compactness of the spray head 220.

[0168] It is understood that when the guiding direction of the first spray port 2201, the second spray port 2202, or the third spray port 2203 is toward the inner wall 102 of the pot assembly 100, and there are multiple corresponding spray ports, the multiple corresponding spray ports can be arranged at intervals along the circumference of the pot assembly 100 so that each first spray port 2201 can spray onto different positions of the inner wall 102 of the pot assembly 100.

[0169] It is understood that when the guiding direction of the first spray port 2201, the second spray port 2202, or the third spray port 2203 is toward the inner bottom wall 103 or the inner top wall of the pot assembly 100, and there are multiple corresponding spray ports, the multiple corresponding spray ports can be arranged at intervals along the extension direction of the aforementioned inner bottom wall 103 or the inner top wall, so that each second spray port 2202 can spray onto different positions of the inner bottom wall 103 or the inner top wall of the pot assembly 100.

[0170] It is understandable that when the guiding direction of the first spray port 2201, the second spray port 2202, or the third spray port 2203 is inclined to the height direction of the cooking appliance, and there are multiple corresponding spray ports, the multiple corresponding spray ports are arranged at intervals along the circumference of the pot body assembly 100, thereby further increasing the spray range of the spray assembly 200 when spraying fluid medium through the corresponding spray ports.

[0171] In some examples, the output pressure of the pumping unit 230 is adjustable.

[0172] In this technical solution, the output pressure of the pumping unit 230 can be adjusted, thereby improving the controllability of the pressure of the fluid medium sprayed by the spray assembly 200. This facilitates spraying fluid media with different pressures in combination with different cooking processes, which is beneficial to further improve the adaptability of the liquid injection process to different cooking processes. Furthermore, by adjusting the output pressure of the pumping unit 230, the initial velocity of the fluid medium flowing out of each spray nozzle can be changed, thereby enabling the control of the distribution range of the fluid medium after flowing out of the nozzle head 220. This is beneficial to further improve the flexibility and controllability of the spray assembly 200.

[0173] For example, when the spraying direction of the aforementioned spray assembly 200 is inclined relative to the height direction of the cooking appliance and away from the inner top wall of the pot assembly 100, water can be added by the aforementioned spray assembly 200 when the cooking appliance is steaming low-sugar rice. Accordingly, by adjusting the output pressure of the pumping unit 230, the initial velocity of the fluid medium sprayed by the spray assembly 200 can be adjusted, so that the fluid medium can fall on different positions on the rice under the action of gravity, so that the water sprayed by the spray assembly 200 can more evenly flush out the sugar in the rice.

[0174] For example, when the spray direction of the aforementioned spray assembly 200 is vertical or substantially vertically directed towards the inner bottom wall 103 of the pot assembly 100, water can be added using the aforementioned spray assembly 200 when cooking noodles. Correspondingly, the impact force of the fluid medium on the food in the cooking chamber 101 can be changed by adjusting the output pressure of the pumping unit 230. This facilitates the use of the fluid medium to agitate the broth used for cooking noodles while preventing the fluid medium from causing a violent impact on the food, thus ensuring the appearance of the noodles after cooking.

[0175] like Figures 1 to 3 As shown, in some examples, the pumping unit 230 includes: a liquid supply pump 231, the inlet end of which is connected to the liquid storage chamber 2101; and a liquid supply pipe 232, which is connected between the outlet end of the liquid supply pump 231 and the nozzle 220.

[0176] In this technical solution, the aforementioned pumping unit 230 may include a liquid supply pump 231 and a liquid supply pipe 232. The liquid outlet of the aforementioned liquid supply pump 231 is connected to the nozzle 220 through the aforementioned liquid supply pipe 232, and the liquid inlet of the liquid supply pump 231 is connected to the liquid storage chamber 2101. The liquid supply pump 231 can provide power for the fluid medium in the liquid storage chamber 2101 to flow to the nozzle 220, and the fluid medium output by the liquid supply pump 231 can flow to the nozzle 220 through the liquid supply pipe 232. Based on the aforementioned configuration, the relative position between the liquid supply pump 231 and the nozzle 220 can be set more flexibly, which is beneficial to improving the space utilization of the cooking appliance.

[0177] like Figures 2 to 6 As shown, in some examples, the spray head 220 includes: a spray head body 221 having a first spray port 2201 and a second spray port 2202; and a connecting shaft 222 disposed on the pot body assembly 100, wherein the spray head body 221 is rotatably connected to the connecting shaft 222.

[0178] In the technical solution, the aforementioned spray head 220 may include a spray head body 221 and a connecting shaft 222 connected to each other. The connecting shaft 222 is disposed on the pot body assembly 100. The spray head body 221 forms the aforementioned first spray port 2201 and second spray port 2202. That is, the spray assembly 200 can spray fluid medium into the cooking cavity 101 through the spray head body 221. The spray head 220 can rotate relative to the connecting shaft 222, thereby adjusting the communication relationship between the output end of the pumping unit 230 and each channel during the rotation, so that the spray assembly 200 can output fluid medium through different spray holes.

[0179] It is understandable that the aforementioned spray head 220 may also have the aforementioned third spray nozzle 2203.

[0180] like Figures 1 to 3As shown, in some examples, the pot assembly 100 includes: a pot body portion 110 having a pot opening and a cooking cavity 101; a pot lid portion 120 for covering or opening the pot opening, and the output end of the spray assembly 200 is located in the pot lid portion 120.

[0181] In this technical solution, the aforementioned pot assembly 100 may include a pot body portion 110 and a pot lid portion 120. The aforementioned cooking cavity 101 is formed in the pot body portion 110, and the pot body portion 110 also has a pot opening that communicates with the cooking cavity 101. The aforementioned pot lid portion 120 can be used to cover or open the pot opening to facilitate the addition of ingredients into the cooking cavity 101 or to improve the sealing of the cooking cavity 101. The output end of the aforementioned spray assembly 200 is disposed on the pot lid portion 120, so that the position of the output end of the spray assembly 200 can be relatively high, so that the fluid medium can flow into the cooking cavity 101 under the action of gravity. At the same time, it is beneficial to increase the coverage of the cooking cavity 101 by the spray assembly 200 and facilitate the spray assembly 200 to deliver the fluid medium to different positions in the cooking cavity 101.

[0182] It is understood that the spray assembly 200 outputs fluid medium through its output end. For example, when the spray assembly 200 has the aforementioned spray ports, the aforementioned spray ports are also the output ends of the spray assembly 200.

[0183] In some examples, the spraying direction of the spray assembly includes: a direction perpendicular to the inner wall of the pot assembly; and / or a direction perpendicular to the inner bottom wall of the pot assembly; and / or a direction perpendicular to the inner top wall of the pot assembly; and / or a direction inclined to the height direction of the cooking appliance and away from the inner top wall of the pot assembly; and / or a direction inclined to the height direction of the cooking appliance and away from the inner bottom wall of the pot assembly.

[0184] In this technical solution, the feasible spraying directions of the spray assembly 200 can include at least one of the following five directions: a direction perpendicular to the inner wall of the pot assembly, a direction perpendicular to the inner bottom wall of the pot assembly, a direction perpendicular to the inner top wall of the pot assembly, a direction inclined to the height direction of the cooking appliance and away from the inner top wall of the pot assembly, and a direction inclined to the height direction of the cooking appliance and away from the inner bottom wall of the pot assembly. This can improve the diversity of the fluid medium injection method of the spray assembly 200, which is conducive to improving the adaptability of the cooking appliance to different cooking processes, ensuring the cooking effect of the cooking appliance, and at the same time saving the amount of spray assembly used in the cooking appliance, which is conducive to ensuring the miniaturization level of the cooking appliance.

[0185] Understandably, in conjunction with the foregoing, when the spray direction is perpendicular to the inner wall 102 of the pot assembly 100, the spray assembly 200 is suitable for adding liquid into the cooking cavity during the stir-frying process to ensure the texture of the food after stir-frying; when the spray direction is perpendicular to the inner bottom wall 103 of the pot assembly 100, the spray assembly is suitable for adding liquid or gas into the cooking cavity 101 during the cooking process to agitate the food and the cooking liquid; when the spray direction is perpendicular to the inner top wall of the pot assembly 100, or inclined to the cooking cavity... When the direction of the spraying device is at the height of the cooking appliance and away from the inner bottom wall 103 of the pot assembly 100, the spraying device 200 is adapted to output water vapor into the cooking chamber 101 during the steaming of food, or to output low-temperature air into the cooking chamber 101 after cooking, so as to improve the steaming efficiency of the food or accelerate the cooling of the food; when the spraying direction is inclined to the height of the cooking appliance and away from the inner top wall of the pot assembly 100, the spraying device 200 is adapted to spray liquid into the cooking chamber 101 during the steaming of low-sugar rice, so as to rinse the rice and reduce the sugar content of the rice.

[0186] like Figures 1 to 6 As shown, a cooking appliance is provided according to a second aspect of the present disclosure, comprising: a pot body assembly 100 having a cooking cavity 101; and a spray assembly 200 for delivering a fluid medium into the cooking cavity 101, wherein the spray direction of the spray assembly 200 is adjustable between a sixth direction and a seventh direction, and the preset direction range includes a first direction and a second direction; wherein the sixth direction and the seventh direction are two different directions among the following: a direction perpendicular to the inner sidewall 102 of the pot body assembly 100, a direction perpendicular to the inner bottom wall 103 of the pot body assembly 100, a direction perpendicular to the inner top wall of the pot body assembly 100, a direction inclined to the height direction of the cooking appliance and away from the inner top wall of the pot body assembly 100, and a direction inclined to the height direction of the cooking appliance and away from the inner bottom wall 103 of the pot body assembly 100.

[0187] The cooking appliance provided in this embodiment includes a pot body assembly 100 and a spray assembly 200. The pot body assembly 100 forms a cooking cavity 101, which can accommodate the food to be cooked, providing space for cooking. The spray assembly 200 can be used to deliver a fluid medium into the cooking cavity 101, thereby improving the convenience of injecting liquid into the cooking cavity 101 during cooking and enhancing the ease of use of the cooking appliance. Furthermore, the spray direction of the spray assembly 200 can be adjusted between a sixth direction and a seventh direction, allowing for controllability within a certain range. This provides high flexibility and controllability. Correspondingly, by adjusting the spray direction of the spray assembly 200, the fluid medium can be sprayed into different areas within the cooking cavity 101, increasing the diversity of fluid medium injection methods. This enhances the adaptability of the cooking appliance to different cooking processes, ensuring the cooking effect of the appliance. At the same time, it reduces the amount of spray assembly 200 used, contributing to the miniaturization of the cooking appliance.

[0188] It should be noted that the spray direction of the aforementioned spray assembly 200 can be adjusted between the sixth and seventh directions, which means that the spray assembly 200 has multiple feasible spray directions. All of the aforementioned feasible spray directions are located within the angle range between the aforementioned sixth and seventh directions and are different from each other. The spray direction of the spray assembly 200 during operation can be at least one of the aforementioned multiple feasible spray directions and can be switched between the aforementioned multiple feasible spray directions. The aforementioned angle range includes the sixth and seventh directions. It is understood that the sixth and seventh directions can be two different directions among the following: the direction perpendicular to the inner sidewall 102 of the pot assembly 100, the direction perpendicular to the inner bottom wall 103 of the pot assembly 100, the direction perpendicular to the inner top wall of the pot assembly 100, the direction inclined to the height direction of the cooking utensil and away from the inner top wall of the pot assembly 100, and the direction inclined to the height direction of the cooking utensil and away from the inner bottom wall 103 of the pot assembly 100. That is, the sixth and seventh directions can be any combination of any two of the aforementioned five directions. Accordingly, the feasible spraying direction of the spraying component 200 is within the angle range of the aforementioned sixth and seventh directions and can include the aforementioned sixth and seventh directions. In practical applications, the specific directions of the sixth and seventh directions can be selected according to actual needs, and no further restrictions are imposed here.

[0189] For example, such as Figure 2 As shown, some feasible spray directions of the spray assembly 200 may include, but are not limited to, those shown. Figure 2The directions indicated by the dashed lines F1 and / or F2 and / or F3 with arrows are as follows: F1 schematically represents a direction perpendicular to the inner wall of the pot assembly 100; F2 schematically represents a direction perpendicular to the inner bottom wall of the pot assembly; and F3 schematically represents a direction inclined to the height of the cooking appliance and away from the inner top wall of the pot assembly. It is understood that in practical applications, the feasible spray directions of the spray assembly 200 are not limited to the directions indicated by the aforementioned dashed lines F1 and / or F2 and / or F3 with arrows. For example, they may also include directions perpendicular to the inner top wall of the pot assembly 100, and / or directions inclined to the height of the cooking appliance and away from the inner bottom wall of the pot assembly, etc.

[0190] It is understood that the inner wall of the pot body assembly 100 can form the aforementioned cooking cavity 101, and the inner wall of the pot body assembly 100 can include an inner top wall, the aforementioned inner side wall 102, and the aforementioned inner bottom wall 103. The aforementioned inner bottom wall 103 refers to the portion of the inner wall of the pot body assembly 100 opposite to the pot opening, and the aforementioned inner top wall refers to the portion of the inner wall of the pot body assembly 100 covering the pot opening. The aforementioned inner top wall can be located in the pot lid portion 120 of the pot body assembly 100. The aforementioned inner side wall 102 is the portion of the inner wall of the pot body assembly 100 located between the aforementioned inner top wall and inner bottom wall 103. The aforementioned inner bottom wall 103 and the aforementioned inner top wall are arranged opposite each other along the height direction of the cooking appliance, and the position height of the aforementioned inner bottom wall is lower than the position height of the aforementioned inner top wall. Accordingly, when the spray direction of the spray assembly 200 is directed toward the inner wall 102 of the pot assembly 100, the spray direction of the spray assembly 200 has a high degree of horizontality, that is, the spray direction of the spray assembly 200 is perpendicular or approximately perpendicular to the height direction of the cooking appliance; when the spray direction of the spray assembly 200 is the aforementioned first direction or second direction, the spray direction of the spray assembly 200 has a high degree of verticality, that is, the spray direction of the spray assembly 200 is parallel or approximately parallel to the height direction of the cooking appliance.

[0191] It is understood that the spray assembly 200 can output a fluid medium along the aforementioned sixth direction. This sixth direction can be one of the following: a direction perpendicular to the inner wall 102 of the pot assembly 100; a direction perpendicular to the inner bottom wall 103 of the pot assembly 100; a direction perpendicular to the inner top wall of the pot assembly 100; a direction inclined to the height direction of the cooking appliance and away from the inner top wall of the pot assembly 100; or a direction inclined to the height direction of the cooking appliance and away from the inner bottom wall 103 of the pot assembly 100. It is understood that when the sixth direction is perpendicular to the inner wall 102 of the pot assembly 100, the spray assembly 200 is suitable for adding liquid into the cooking cavity during the stir-frying process to ensure the texture of the food after stir-frying. When the sixth direction is perpendicular to the inner bottom wall 103 of the pot assembly 100... In the case of the sixth direction, the spray assembly is adapted to inject liquid or gas into the cooking cavity 101 during the cooking process to agitate the food and the cooking broth; in the case of the sixth direction being perpendicular to the inner top wall of the pot assembly 100, or inclined to the height of the cooking appliance and away from the inner bottom wall 103 of the pot assembly 100, the spray assembly 200 is adapted to output water vapor into the cooking cavity 101 during the steaming process, or output low-temperature air into the cooking cavity 101 after cooking, so as to improve the steaming efficiency of the food or accelerate the cooling of the food; in the case of the sixth direction being inclined to the height of the cooking appliance and away from the inner top wall of the pot assembly 100, the spray assembly 200 is adapted to spray liquid into the cooking cavity 101 during the steaming of low-sugar rice to rinse the rice and reduce the sugar content of the rice.

[0192] Similarly, the spray assembly 200 can output fluid medium along the aforementioned seventh direction. This seventh direction can be one of the following: a direction perpendicular to the inner wall 102 of the pot assembly 100; a direction perpendicular to the inner bottom wall 103 of the pot assembly 100; a direction perpendicular to the inner top wall of the pot assembly 100; a direction inclined to the height direction of the cooking appliance and away from the inner top wall of the pot assembly 100; or a direction inclined to the height direction of the cooking appliance and away from the inner bottom wall 103 of the pot assembly 100. It is understood that, in conjunction with the foregoing, when the seventh direction is perpendicular to the inner wall 102 of the pot assembly 100, the spray assembly 200 is suitable for adding liquid into the cooking cavity during the stir-frying process to ensure the texture of the food after stir-frying; when the seventh direction is perpendicular to the inner bottom wall 103 of the pot assembly 100... In the case of the seventh direction, the spray assembly is adapted to inject liquid or gas into the cooking cavity 101 during the cooking process to agitate the food and the cooking broth; in the case of the seventh direction being perpendicular to the inner top wall of the pot assembly 100, or inclined to the height direction of the cooking appliance and away from the inner bottom wall 103 of the pot assembly 100, the spray assembly 200 is adapted to output water vapor into the cooking cavity 101 during the steaming process, or output low-temperature air into the cooking cavity 101 after cooking, so as to improve the steaming efficiency of the food or accelerate the cooling of the food; in the case of the seventh direction being inclined to the height direction of the cooking appliance and away from the inner top wall of the pot assembly 100, the spray assembly 200 is adapted to spray liquid into the cooking cavity 101 during the steaming of low-sugar rice to rinse the rice and reduce the sugar content of the rice.

[0193] It should be noted that the sixth direction can be perpendicular to the inner top wall of the pot assembly 100, and the seventh direction can be perpendicular to the inner bottom wall 103 of the pot assembly 100, so as to expand the spraying range of the spraying assembly 200 in practical applications, making it easier for the spraying assembly 200 to spray fluid medium to different positions in the cooking cavity 101, which is conducive to further improving the adaptability of the cooking appliance to different cooking processes and providing a more reliable guarantee for the cooking effect of the cooking appliance.

[0194] To facilitate understanding of some feasible uses of the cooking appliances provided in this disclosure during actual cooking, several application scenarios of different spray directions of the spray assembly 200 are illustrated herein by way of example.

[0195] When the spraying direction of the spraying assembly 200 is perpendicular or approximately perpendicular to the inner wall 102 of the pot assembly 100, the spraying assembly 200 can easily add liquid into the cooking cavity 101 during the cooking process. The liquid can be, but is not limited to, water or broth. Accordingly, when the cooking process reaches a certain stage or the pot temperature reaches a certain level, the spraying assembly 200 can spray liquid onto the inner wall 102 of the pot assembly 200, thereby avoiding direct spraying of low-temperature water onto the food in the bottom area of ​​the cooking cavity 101. The water sprayed by the spraying assembly 200 can easily come into contact with the inner wall 102 first and slide down the inner wall 102 towards the inner bottom wall 103 under the action of gravity. During the sliding process, the water can absorb the heat of the pot assembly 100 through the inner wall 102, so that it has a higher temperature when it comes into contact with the food in the bottom area of ​​the cooking cavity 101, which is beneficial to improving the taste of the food after cooking.

[0196] When the spray direction of the spray assembly 200 is perpendicular or substantially perpendicular to the inner bottom wall 102 of the pot assembly 100, the spray assembly 200 can easily add liquid or gas into the cooking cavity during the cooking process. The liquid can be, but is not limited to, water or broth, and the gas can be, but is not limited to, air. Accordingly, when the cooking process reaches a certain stage or the pot temperature reaches a certain level, the spray assembly 200 can spray liquid onto the inner bottom wall 103 of the pot assembly 200 so that the water sprayed by the spray assembly 200 can disturb the broth used for cooking dumplings or noodles. It is understood that during the cooking process of pasta, the water can be water at a lower temperature, which helps to prevent the pasta from gelatinizing and ensures the taste of the cooked food.

[0197] When the spray direction of the spray assembly 200 is perpendicular or approximately perpendicular to the inner top wall 102 of the pot assembly 100, or when the spray direction is inclined to the height direction of the cooking appliance and away from the inner bottom wall of the pot assembly, the spray assembly 200 can easily inject gas into the cooking cavity during the steaming process. The liquid mentioned above can be water vapor to provide heat and moisture for the steaming of the food. Alternatively, after cooking is completed, the spray assembly 200 can inject low-temperature air into the cooking cavity 101 so that the low-temperature air preferentially cools the higher areas in the cooking cavity 101. Then, the low-temperature air can flow downward in the cooking cavity 101 to increase the temperature drop rate in the cooking cavity 101, which is beneficial to lower the temperature of the food and makes it easier for the user to quickly open the lid and take out the food after cooking.

[0198] When the spray direction of the spray assembly 200 is inclined to the height direction of the cooking appliance and away from the inner bottom wall of the pot assembly, the spray assembly 200 can easily add liquid into the cooking cavity during the steaming of low-sugar rice. The liquid can be water. Accordingly, the water output by the spray assembly 200 can be sprayed onto the rice to be steamed to rinse the rice, thereby reducing the sugar content of the rice. In this case, the output pressure of the spray assembly 200 can be adjusted, so that water can be sprayed onto different parts of the rice to enhance the sugar rinsing effect. It is understood that the cooking appliance may also include a low-sugar pot, which is detachably installed in the cooking cavity for holding the rice to be steamed. The aforementioned low-sugar pot can be equipped with a liquid baffle. When the spray assembly 200 outputs liquid in the direction that is inclined to the height of the cooking appliance and away from the inner bottom wall of the pot assembly, the liquid baffle can be used to receive the liquid output by the spray assembly 200 and guide the liquid into the pot space, so that the fluid medium can be sprayed more evenly on the rice to be steamed in the pot space, while reducing the impact of the liquid flow on the rice and ensuring the flatness of the rice surface.

[0199] It is understood that the above examples of several different spraying directions of the spray assembly 200 are only for illustrating some feasible ways of using the cooking appliance provided in this disclosure. In practical applications, the spraying direction of the spray assembly 200 can also be adjusted in combination with other different usage scenarios or cooking processes, which will not be listed here.

[0200] It should be noted that, in practical applications, the cooking appliances provided in this disclosure can be used as, but are not limited to, electric pressure cookers, electric steamers, electric saucepans, electric frying pans, multi-functional cookers, and other cooking appliances.

[0201] Taking the aforementioned cooking appliance as a multi-functional pot that combines stir-frying, boiling, and steaming functions as an example, the ingredients to be cooked can be placed inside the cooking cavity 101, and the fluid medium can be water. When stir-frying the ingredients, the spray direction of the spray component 200 can be adjusted to face the inner wall 102 of the pot body component 100. When the stir-frying process reaches a certain stage or the pot body temperature reaches a certain level, the spray component 200 can spray water towards the inner wall 102 of the pot body component 100, thereby avoiding direct spraying of low-temperature water onto the ingredients at the bottom of the cooking cavity 101. This also allows the water sprayed by the spray component 200 to easily contact the inner wall 102 first and slide down the inner wall 102 towards the inner bottom wall 103 under the action of gravity. Water can absorb heat from the pot assembly 100 through the aforementioned inner wall 102, so that it has a higher temperature when it comes into contact with the food in the bottom area of ​​the cooking cavity 101, which is beneficial to improving the taste of the food after stir-frying. When cooking the food, such as dumplings or noodles, the spray direction of the spray assembly 200 can be adjusted to face the inner bottom wall 103 of the pot assembly 100. When the cooking process reaches a certain level or the pot temperature reaches a certain level, the spray assembly 200 can spray water towards the inner bottom wall 103 of the pot assembly 100 so that the water sprayed by the spray assembly 200 can disturb the soup used to cook dumplings or noodles. It can be understood that during the cooking process of noodles, the aforementioned water can be water at a lower temperature, which is beneficial to avoid the noodles from becoming gelatinized and to ensure the taste of the food after cooking. Other application scenarios of cooking appliances and the spray direction of the spray component 200 in other cooking processes will not be listed here. However, it is easy to understand that the cooking appliances provided in this embodiment, based on the aforementioned settings, can improve the adaptability of the liquid injection method of the cooking appliances to different cooking processes and enhance the cooking effect of the cooking appliances.

[0202] Understandably, in practical applications, cooking appliances can also utilize the spray assembly 200 for operations requiring the participation of a fluid medium, such as depressurizing the cooking chamber 101, adding fluid medium for cooking ingredients, and cleaning the pot body assembly 100, thereby further improving the ease of use of cooking appliances.

[0203] It is understandable that, in practical applications, there can be multiple ways to achieve adjustable spray direction of the spray assembly 200. For example, the spray assembly 200 can have spray nozzles for outputting fluid media. Correspondingly, the spray direction of the spray assembly 200 can be adjusted by making the position of the spray nozzles movable. Alternatively, the spray assembly 200 can have multiple spray nozzles facing different directions, and the opening and closing states of the nozzles with different directions can be controlled independently, thereby achieving spraying in different directions. In practical applications, the method for achieving adjustable spray direction of the spray assembly 200 can be selected based on actual needs, and no further limitations are imposed here.

[0204] In some feasible examples, the aforementioned spray assembly 200 can be disposed on the inner top wall of the pot body assembly 100, which is beneficial to improve the spraying efficiency of the spray assembly 200 and the coverage of the cooking cavity 101; for example, the aforementioned spray assembly 200 can be disposed in the middle region of the inner top wall of the pot body assembly 100.

[0205] In some examples, the spray assembly 200 includes: a spray head 220 having a first spray port 2201 and a second spray port 2202, the first spray port 2201 being open in a third direction and the second spray port 2202 being open in a fourth direction, both the third and fourth directions being located between the sixth and seventh directions, and the third direction being different from the fourth direction; and a pumping section 230 connected to the spray head 220; wherein the spray head 220 is movable relative to the pumping section 230 so that the output end of the pumping section 230 is connected to the first spray port 2201 or the second spray port 2202.

[0206] In some examples, the third direction is a direction perpendicular to the inner wall of the pot assembly, or a direction perpendicular to the inner bottom wall of the pot assembly, or a direction perpendicular to the inner top wall of the pot assembly, or a direction inclined to the height direction of the cooking appliance and away from the inner top wall of the pot assembly, or a direction inclined to the height direction of the cooking appliance and away from the inner bottom wall of the pot assembly; the fourth direction is a direction perpendicular to the inner wall of the pot assembly, or a direction perpendicular to the inner bottom wall of the pot assembly, or a direction perpendicular to the inner top wall of the pot assembly, or a direction inclined to the height direction of the cooking appliance and away from the inner top wall of the pot assembly, or a direction inclined to the height direction of the cooking appliance and away from the inner bottom wall of the pot assembly.

[0207] In some examples, the output end of the pumping section 230 is located on the inner wall of the pot assembly 100, and the spray head 220 is rotatably disposed on the inner wall of the pot assembly 100 and covers the output end of the pumping section 230. The spray head 220 has a first channel 2204 and a second channel 2205 formed on the side facing the output end of the pumping section 230. The first channel 2204 and the second channel 2205 are arranged at intervals along the rotation direction of the spray head 220. The first channel 2204 is connected to the first spray port 2201, and the second channel 2205 is connected to the second spray port 2202.

[0208] In some examples, the nozzle 220 also forms a third spray port 2203, which is open along a fifth direction. The fifth direction is located between the sixth and seventh directions and is different from the third and fourth directions. A third channel 2206 is also formed on the side of the nozzle 220 facing the output end of the pumping unit 230. The third channel 2206 is connected to the third spray port 2203. The first channel 2204, the second channel 2205 and the third channel 2206 are arranged at intervals along the rotation direction of the nozzle 220.

[0209] In some examples, the conduction area of ​​the inlet end of the third channel 2206 is greater than the conduction area of ​​the output end of the pumping unit 230.

[0210] In some examples, the inlet area of ​​the first channel 2204 and the second channel 2205 is greater than the outlet area of ​​the pumping unit 230.

[0211] In some examples, the spray assembly 200 further includes a drive unit 240 connected to the spray head 220 for driving the spray head 220 to rotate.

[0212] In some examples, the drive unit 240 includes: a drive motor 241; a drive gear 242 connected to the drive motor 241; and a transmission tooth 2207 formed on the periphery of the nozzle 220, which meshes with the drive gear 242.

[0213] In some examples, there are multiple first spray nozzles 2201 and / or second spray nozzles 2202 and / or third spray nozzles 2203.

[0214] In some examples, the output pressure of the pumping unit 230 is adjustable.

[0215] In some examples, the pumping unit 230 includes: a liquid supply pump 231, the inlet end of which is connected to the liquid storage chamber 2101; and a liquid supply pipe 232, which is connected between the outlet end of the liquid supply pump 231 and the nozzle 220.

[0216] In some examples, the nozzle 220 includes: a nozzle body 221 having a first spray port 2201 and a second spray port 2202; and a connecting shaft 222 disposed on the pot assembly 100, wherein the nozzle body 221 is rotatably connected to the connecting shaft 222.

[0217] In some examples, the pot assembly 100 includes: a pot body portion 110 having a pot opening and a cooking cavity 101; a pot lid portion 120 for covering or opening the pot opening, and the output end of the spray assembly 200 is located in the pot lid portion 120.

[0218] In some examples, the spraying direction of the spray assembly includes: a direction perpendicular to the inner wall of the pot assembly; and / or a direction perpendicular to the inner bottom wall of the pot assembly; and / or a direction perpendicular to the inner top wall of the pot assembly; and / or a direction inclined to the height direction of the cooking appliance and away from the inner top wall of the pot assembly; and / or a direction inclined to the height direction of the cooking appliance and away from the inner bottom wall of the pot assembly.

[0219] like Figure 7 As shown, a third aspect of the present disclosure provides a method for controlling a cooking appliance, used for any of the cooking appliances described in the first or second aspect above, the aforementioned control method comprising:

[0220] Step S701: In response to the cooking command, determine the target spray direction;

[0221] Specifically, the cooking appliance can respond to cooking instructions issued by the user, and accordingly, the cooking appliance can determine the target spray direction when injecting liquid into the cooking cavity 101 based on the cooking instructions.

[0222] It is understood that the aforementioned cooking instructions may include the aforementioned target injection direction, so that the aforementioned target injection direction can be directly determined by the cooking instructions; or, the aforementioned cooking instructions may include a target cooking mode, which may be a cooking mode based on cooking technology, such as steaming mode, boiling mode, or stir-frying mode. Each target cooking mode corresponds to a target injection direction, so that the aforementioned target injection direction can be determined according to the aforementioned target cooking mode to improve the matching between the target injection direction and the cooking technology. The correspondence between the aforementioned target cooking mode and the target injection direction may be set at the factory or set by the user.

[0223] It is understood that the aforementioned target spray direction is a direction between the aforementioned first direction and the aforementioned second direction, or a direction between the aforementioned sixth direction and the seventh direction. Accordingly, the target spray direction can be the first direction, the second direction, the sixth direction, or the seventh direction, or it can be a direction between the first direction and the second direction that is different from the first direction and the second direction, or it can be a direction between the sixth direction and the seventh direction that is different from the sixth direction and the seventh direction. That is, the target spray direction is the spray direction that a spray assembly 200 can adjust to.

[0224] Step S702: Generate a request message to adjust the spray direction of the spray assembly 200 according to the target spray direction;

[0225] Specifically, when the target spray direction is determined, a request message can be generated based on the target spray direction. The request message is used to request the adjustment of the spray direction of the spray assembly 200 to the target spray direction, so that the user or cooking appliance can adjust the spray direction of the spray assembly 200 according to the request message.

[0226] It is understood that when the spray direction of the aforementioned spray assembly 200 is manually adjustable, the request recipient of the aforementioned request information can be a user. For example, the cooking appliance may have a prompt module, which can be used to generate prompt information based on the aforementioned request information to prompt the user to adjust the spray direction of the spray assembly 200 accordingly. The aforementioned prompt information may include, but is not limited to, acoustic prompts such as buzzers, electronic rings, and voice announcements, and / or optical prompts such as graphic displays, text displays, and light information. When the spray direction of the aforementioned spray assembly 200 is electrically adjustable, the cooking appliance can automatically control the spray assembly 200 to adjust the spray direction accordingly based on the aforementioned request information.

[0227] Step S702: When the spray direction of the spray assembly 200 is consistent with the target spray direction, control the spray assembly 200 to deliver fluid medium into the cooking chamber 101 in response to the injection command.

[0228] Specifically, when the spray direction of the spray assembly 200 is adjusted to the target spray direction, the spray assembly 200 can respond to the injection command and deliver the fluid medium into the cooking chamber 101 under the injection command, thereby injecting the fluid medium into the cooking chamber 101 in accordance with the target spray direction.

[0229] It is understandable that the aforementioned injection command can be issued by the user or automatically generated by the cooking program of the cooking appliance after it has reached a certain stage; no further restrictions are imposed here.

[0230] Taking the target cooking mode of the cooking appliance as one of the stir-frying, boiling, and steaming modes as an example, the aforementioned fluid medium can be a liquid or a gas. The aforementioned liquid can be, but is not limited to, water or broth used for cooking ingredients, and the aforementioned gas can be, but is not limited to, air or steam. When the target cooking mode is the stir-frying mode, for example, when stir-frying meat or vegetables, the aforementioned target spray direction can be towards the inner wall 102 of the pot assembly 100, for example, perpendicular to the inner wall 102 of the pot assembly 100. It can be understood that when the spray direction of the spray assembly 200 is towards the aforementioned inner wall 102, the spray direction of the spray assembly 200 has a high degree of horizontality, that is, the spray direction of the spray assembly 200 is perpendicular or approximately perpendicular to the depth direction of the cooking cavity 101; the aforementioned injection command can be automatically generated when the cooking time and / or the pot temperature reaches a certain level, and the aforementioned fluid medium can be... When responding to the aforementioned injection command, the spray assembly 200 can spray water toward the inner wall 102 of the pot assembly 100, thereby avoiding direct spraying of low-temperature water onto the food in the bottom area of ​​the cooking cavity 101. This also allows the water sprayed by the spray assembly 200 to easily come into contact with the inner wall 102 and slide down along the inner wall 102 toward the inner bottom wall 103 under the action of gravity. During the sliding process, the water can absorb heat from the pot assembly 100 through the inner wall 102, so that it has a higher temperature when it comes into contact with the food in the bottom area of ​​the cooking cavity 101, which is beneficial to improving the taste of the food after cooking.

[0231] When the target cooking mode is the boiling mode, such as when boiling dumplings or noodles, the aforementioned target spray direction can be towards the inner bottom wall 103 of the pot assembly 100, for example, perpendicular to the inner bottom wall 103 of the pot assembly 100. It is understood that when the spray direction of the spray assembly 200 is towards the aforementioned inner bottom wall 103, the spray direction of the spray assembly 200 has a high degree of verticality, that is, the spray direction of the spray assembly 200 is parallel or approximately parallel to the depth direction of the cooking cavity 101. The aforementioned injection command can be automatically generated when the cooking time and / or the pot temperature reaches a certain level. The aforementioned fluid medium can be water. When responding to the aforementioned injection command, the spray assembly 200 can spray water towards the inner side wall 102 of the pot assembly 100, so that the water sprayed by the spray assembly 200 can disturb the soup used for boiling dumplings or noodles. It is understood that during the cooking process of pasta, the aforementioned water can be water at a lower temperature, which helps to avoid pasta gelatinization and ensure the taste of the food after cooking.

[0232] When the target cooking mode is steaming, such as steaming low-sugar rice, the aforementioned target spray direction can be tilted towards the height of the cooking appliance; the aforementioned injection command can be automatically generated when the cooking time and / or the pot temperature reaches a certain level; the aforementioned fluid medium can be water; when responding to the aforementioned injection command, the spray assembly 200 can spray water in a direction tilted towards the height of the cooking appliance, so that the liquid flow can easily cover a larger area within the cooking cavity 101, which is beneficial for the spray assembly 200 to inject the fluid medium into the cooking cavity 101 more evenly, making it easier for the water sprayed by the spray assembly 200 to rinse the rice more evenly, thereby reducing the sugar content of the rice. When steaming other ingredients, the aforementioned target spray direction can be towards the inner top wall of the pot assembly 100, for example, a direction perpendicular to the inner top wall of the pot assembly 100, or a direction inclined to the height of the cooking appliance and away from the inner bottom wall 103 of the pot assembly 100. The aforementioned injection command can be automatically generated when the cooking time and / or the pot temperature reaches a certain level. The aforementioned fluid medium can be water vapor. When responding to the aforementioned injection command, the spray assembly 200 can inject water vapor into the cooking cavity 101 to provide heat and moisture for the steaming of the ingredients and increase the steam concentration in the cooking cavity 101, which is beneficial to promoting the steaming efficiency of the ingredients.

[0233] When cooking is complete, the aforementioned target spray direction can be towards the inner top wall of the pot assembly 100, for example, a direction perpendicular to the inner top wall of the pot assembly 100, or a direction inclined to the height of the cooking appliance and away from the inner bottom wall 103 of the pot assembly 100; the aforementioned injection command can be automatically generated when cooking is complete, the aforementioned fluid medium can be air, and when the spray assembly 200 responds to the aforementioned injection command, it can inject lower temperature air into the cooking cavity 101 to lower the temperature of the food in the cooking cavity 101, making it convenient for the user to open the lid and take out the food.

[0234] The applications of the spray assembly 200 in other cooking processes will not be listed here, but it is understood that the control method for cooking appliances provided in this disclosure can improve the adaptability of the liquid injection method to different cooking processes and enhance the cooking effect of the cooking appliances by controlling the cooking appliances as described above.

[0235] In summary, the control method for cooking appliances provided in this disclosure can be used to control cooking appliances as proposed in any of the first aspects above. By controlling the spray assembly 200 to spray fluid medium into the cooking chamber 101 in a target spray direction determined based on the cooking command, the diversity of fluid medium injection methods of the cooking appliance can be improved, which is beneficial to improving the adaptability of the cooking appliance to different cooking processes, ensuring the cooking effect of the cooking appliance, improving the automation level of the cooking appliance, and enhancing the user experience of the product.

[0236] In some examples, the aforementioned control methods also include:

[0237] In response to a cooking command, the pot body assembly 100 is heated;

[0238] The aforementioned step S703 includes:

[0239] When the spray direction of the spray assembly 200 is consistent with the target spray direction, and the cooking time reaches the target time and / or the pot body temperature reaches the first target temperature and / or the pressure inside the pot body reaches the first target pressure, the spray assembly 200 is controlled to deliver fluid medium into the cooking chamber 101 in response to the injection command.

[0240] Specifically, when the cooking appliance responds to the aforementioned cooking command, it can heat the pot assembly 100 to provide the necessary heat for cooking the food inside the pot assembly 100, which helps to ensure cooking efficiency and cooking effect. Correspondingly, when the spray direction of the spray assembly 200 is consistent with the target spray direction, and the cooking time reaches the target time and / or the pot temperature reaches the first target temperature and / or the pressure inside the pot reaches the first target pressure, the spray assembly 200 is controlled to respond to the injection command and deliver the fluid medium into the cooking chamber 101 according to the target spray direction, which can further improve the injection timing of the spray assembly 200 and help to provide further assurance for the cooking effect of the cooking appliance.

[0241] It is understood that the situation where the spray direction of the aforementioned spray assembly 200 is consistent with the target spray direction, and the cooking time reaches the target time and / or the pot body temperature reaches the first target temperature and / or the pressure inside the pot body reaches the first target pressure, refers to the situation where the spray direction of the spray assembly 200 is consistent with the target spray direction, and the cooking time and / or the pot body temperature and / or the pressure inside the pot body meet the corresponding conditions.

[0242] It is understood that the aforementioned cooking time refers to the operating time of the cooking appliance after responding to the cooking command. The aforementioned pot body temperature refers to the inner wall temperature of the pot body assembly 100. The aforementioned pot body pressure refers to the internal air pressure of the cooking chamber 101.

[0243] It is understood that the aforementioned target duration, first target temperature, and first target pressure can be determined in conjunction with the recipe of the ingredients to be cooked. For example, when the target cooking mode is stir-frying, the aforementioned target duration can be the time it takes for the cooking appliance to move from the cooking command to the stir-frying stage, and the aforementioned first target temperature can be the highest temperature of the pot assembly 100 during the cooking process; when the target cooking mode is simmering, the aforementioned target duration can be the time it takes for the cooking appliance to move from the cooking command to the boiling stage, and the aforementioned first target temperature can be the boiling temperature of the broth from the simmering ingredients in the pot assembly 100; when the target cooking mode is pressure cooking, the aforementioned first target pressure can be the maximum pressure set during pressure cooking. The aforementioned target duration, first target temperature, and first target pressure can be specifically determined based on actual needs, and will not be listed individually here.

[0244] It is understood that the aforementioned injection command may be automatically generated when the spray direction of the spray component 200 is consistent with the target spray direction, and the cooking time reaches the target time and / or the pot body temperature reaches the first target temperature. No further restrictions are imposed here.

[0245] In some examples, the target spray direction is toward the inner sidewall 102 of the pot assembly 100 or toward the inner bottom wall 103 of the pot assembly 100, and controlling the spray assembly 200 to deliver the fluid medium into the cooking chamber 101 in response to the injection command includes:

[0246] The spray assembly 200 controls the spray system to perform fluid medium output operations multiple times in response to injection commands;

[0247] When the total fluid medium output of the spray assembly 200 reaches the first target output, the spray assembly 200 is controlled to shut down. The first target output is greater than the fluid medium output of the spray assembly 200 in a single fluid medium output operation.

[0248] Specifically, when the aforementioned fluid medium is a liquid, and the aforementioned target spray direction is towards the inner sidewall 102 of the pot assembly 100 or towards the inner bottom wall 103 of the pot assembly 100, during the process of controlling the spray assembly 200 to deliver the fluid medium into the cooking chamber 101 in response to the injection command, the spray assembly 200 can be controlled to perform multiple fluid medium output operations until the total amount of fluid medium output by the spray assembly 200 in multiple fluid medium output operations reaches the first target output amount. This can avoid the spray assembly 200 supplying a large amount of liquid into the cooking chamber 101 at one time, which helps to reduce the impact of the liquid injection process on the cooking environment and provides a guarantee for the cooking effect of the cooking appliance.

[0249] Accordingly, the amount of fluid medium output by the spray assembly 200 in a single fluid medium output operation is less than the first target output amount, thereby avoiding excessive total fluid medium output by the spray assembly 200.

[0250] It is understood that the aforementioned first target output volume and the fluid medium output volume of the aforementioned spray assembly 200 in a single fluid medium output operation can be set according to actual needs, such as the weight of the food to be cooked or the recipe. For example, the first target output volume can be greater than or equal to 100 mL and less than or equal to 300 mL; the fluid medium output volume of the spray assembly 200 in a single fluid medium output operation can be greater than or equal to 30 mL and less than or equal to 150 mL.

[0251] It is understood that the aforementioned fluid medium output operation can be executed more than or equal to two times, such as two, three, four or five times, etc. The goal is to ensure that the total fluid medium output of the spray assembly 200 reaches the aforementioned first target output amount when the fluid medium output operation is executed for the last time. The specific number of times can be set according to actual needs, and no further restrictions are imposed here.

[0252] For example, the spray direction toward the inner sidewall 102 of the pot body assembly 100 can correspond to the stir-frying mode, and the spray direction toward the inner bottom wall 103 of the pot body assembly 100 can correspond to the cooking mode.

[0253] It should be noted that in cooking mode, the output pressure of the spray assembly 200 can be set within a preset pressure range. For example, the output pressure of the spray assembly 200 can be controlled by adjusting the output pressure of the aforementioned pumping unit 230. This ensures that the fluid medium can agitate the broth in the cooking chamber 101 while reducing the impact on the food being cooked, thus helping to maintain the aesthetic appearance of the cooked food. The aforementioned preset pressure range can be determined based on actual tests of different foods to be cooked, and no further restrictions are imposed here.

[0254] In some examples, a preset interval is set between two consecutive fluid medium output operations; or

[0255] All fluid medium output operations were performed when the boiler temperature reached the first target temperature and / or the boiler pressure reached the first target pressure.

[0256] Specifically, a preset interval can be set between two adjacent fluid medium output operations, so that during the cooking process, time can be provided for the pot temperature to recover to the first target temperature in a single fluid medium output operation, which helps to reduce the impact of the liquid injection process on the cooking environment and ensures the cooking effect of the cooking appliance.

[0257] Alternatively, the multiple fluid medium output operations of the spray assembly 200 can all be performed when the pot body temperature reaches the first target temperature and / or the pot body pressure reaches the first target pressure. That is, the fluid medium output operations are controlled to be performed when the pot body temperature reaches or recovers to the first target temperature and / or the pot body pressure recovers to the first target pressure. This avoids excessive continuity between multiple fluid medium output operations, prevents a significant drop in temperature or excessive pressure fluctuation in the cooking chamber 101, helps to reduce the impact of the liquid injection process on the cooking environment, and provides a guarantee for the cooking effect of the cooking appliance.

[0258] It is understood that, in practical applications, the aforementioned preset interval duration can be determined by combining the heating parameters of the pot assembly 100 and the weight of the food to be cooked, ensuring that the multiple fluid medium output operations of the spray assembly 200 are all performed when the pot temperature is close to the first target temperature and / or the pressure inside the pot is close to the first target pressure. No further limitations are imposed here. For example, the preset interval duration can be greater than or equal to 10 seconds and less than or equal to 30 seconds, such as 12 seconds, 15 seconds, 20 seconds, or 25 seconds, etc.

[0259] In some examples, the amount of fluid medium output is the same when the spray assembly 200 performs fluid medium output operation more than once, and the first target output amount is an integer multiple of the amount of fluid medium output when the spray assembly 200 performs fluid medium output operation once.

[0260] Specifically, the fluid medium output of the spray assembly 200 can be set to be the same in multiple fluid medium output operations, thereby improving the uniformity of the fluid medium output in multiple fluid medium output operations, which is beneficial to ensuring the cooking effect and reducing the control cost of cooking appliances. Correspondingly, the first target output can be set to an integer multiple of the fluid medium output of the spray assembly 200 in a single fluid medium output operation, thereby improving the control accuracy of the fluid medium output of the spray assembly 200 and reducing the risk that the total fluid medium output of the spray assembly 200 deviates significantly from the first target output.

[0261] In some examples, the target spray is tilted at the height of the cooking appliance, and controlling the spray assembly 200 to deliver a fluid medium into the cooking chamber 101 in response to an injection command includes:

[0262] The spray assembly 200 responds to an injection command by delivering a fluid medium into the cooking chamber 101 at a first preset pressure.

[0263] The output pressure of the spray assembly 200 is controlled to cycle between a first preset pressure and a second preset pressure, wherein the second preset pressure is different from the first preset pressure.

[0264] When the number of times the output pressure of the spray assembly 200 changes from the second preset pressure to the first preset pressure reaches a preset number, the spray assembly 200 is controlled to shut down.

[0265] Specifically, when the target spray direction is tilted to the height direction of the cooking appliance, during the process of controlling the spray assembly 200 to deliver fluid medium into the cooking cavity 101 in response to the injection command, the spray assembly 200 can be controlled to deliver fluid medium into the cooking cavity 101 at a first preset pressure under the injection command. Then, the output pressure of the spray assembly 200 is controlled to cycle between the first preset pressure and the second preset pressure, so as to change the initial velocity of the fluid medium when it flows out of the spray assembly 200, so that the fluid medium falls to different positions in the cooking cavity 101 under the action of gravity, thereby further expanding the spray range and uniformity of the spray assembly 200. Correspondingly, when the number of times the output pressure of the spray assembly 200 changes from the second preset pressure to the first preset pressure reaches a preset number, that is, when the number of cycles reaches a preset number, the spray assembly 200 can be controlled to close to complete the fluid medium injection.

[0266] It is understood that the aforementioned second preset pressure is different from the first preset pressure; for example, the second preset pressure is less than the first preset pressure, that is, the spray assembly 200 can preferentially spray the fluid medium into the cooking cavity 101 at a higher first preset pressure.

[0267] It is understood that the output pressure of the spray assembly 200 can vary continuously between the first preset pressure and the second preset pressure, or it can vary in a stepwise or intermittent manner; no further restrictions are imposed here.

[0268] It is understood that the output pressure of the spray assembly 200 can change periodically between the first preset pressure and the second preset pressure. Accordingly, the output pressure of the spray assembly 200 changes from the first preset pressure to the second preset pressure and then changes from the second preset pressure back to the first preset pressure, which constitutes one cycle. The duration of each cycle can be 5 to 10 seconds.

[0269] It is understood that the total output of fluid medium when the output pressure of the spray assembly 200 changes from the second preset pressure to the first preset pressure a preset number of times can be limited. For example, the total output of fluid medium can be greater than or equal to 100 mL and less than or equal to 300 mL.

[0270] Understandably, the first and second preset pressures can be set according to actual needs, and no further restrictions are imposed here.

[0271] It is understandable that the aforementioned preset number of times can be greater than or equal to two, such as two, three, four or five times, etc. The specific number of times can be set according to actual needs, and no further restrictions are imposed here.

[0272] In some examples, the aforementioned control methods also include:

[0273] In response to cooking instructions, determine the target cooking mode of the cooking appliance;

[0274] When the target cooking mode is steaming or boiling, the pot assembly 100 is heated so that the pot temperature is greater than or equal to the boiling point of the fluid medium.

[0275] The spray assembly 200 is controlled to deliver a fluid medium with a second target output into the cooking chamber 101;

[0276] When the pressure in the cooking chamber 101 reaches the preset pressure, the spray assembly 200 is controlled to deliver a third target output amount of fluid medium into the cooking chamber 101.

[0277] The third target output is determined based on the weight of the food to be cooked in the cooking cavity 101, and the second target output is less than the third target output.

[0278] Specifically, when the cooking appliance responds to a cooking command, a target cooking mode can be determined. The target cooking mode can be a cooking mode based on cooking techniques, such as steaming, boiling, or stir-frying. The aforementioned cooking command can be generated when the ingredients to be cooked have been placed in the cooking cavity 101. When the target cooking mode is steaming or boiling, and the fluid medium is liquid, the pot assembly 100 can be heated to ensure its temperature is not lower than the boiling point of the liquid to be added. Then, the liquid can be delivered into the cooking cavity 101 via the spray assembly 200 until the liquid output of the spray assembly 200 reaches the second target output. During this process, the liquid can come into contact with the hotter inner wall of the pot, from... The rapid boiling and vaporization at a high rate facilitates a faster pressure rise within the cooking chamber 101, shortening the pressure cooking time for the food. Once the pressure in the cooking chamber 101 reaches a preset pressure, the spray assembly 200 can be further controlled to deliver liquid to the cooking chamber 101 for a third target output quantity. This third target output quantity of liquid can be used to cook the food or to generate steam for steaming it. The third target output quantity is determined based on the weight of the food in the cooking chamber 101. The second target output quantity can be less than the third target output quantity, thus ensuring rapid evaporation of the liquid after injection into the cooking chamber 101, guaranteeing a rapid pressure increase within the cooking chamber 101. Simultaneously, based on the aforementioned configuration, the cooking time for the food can be shortened, ensuring the quality of the food's texture, color, and aroma after cooking.
