The control module is at least used to control the increase of the air flow speed of the air flow device when the anti-overflow sensor is triggered by rice soup.
[0031] Compared with the prior art, the utility model has the following beneficial effects:
[0032] In this solution, by setting the first diversion area and the second diversion area on the diversion member, it is possible to simultaneously form air cooling for the upper part and the lower part of the cooking pot liner, thereby achieving a better cooling effect on the cooking pot liner, achieving a better non-sticking effect on the rice in the lower part of the cooking pot liner, and achieving a better anti-overflow effect on the rice soup foam in the upper part of the cooking pot liner.
[0033] In this solution, the position and structure of the diversion member are set so that the air flow can flow better and more smoothly along the outer surface of the cooking pot liner, achieving a larger area of cooling for the cooking pot liner, enabling the cooking pot liner to form the effect of simultaneous cooling of the upper part and the lower part, and achieving better non-sticking and anti-overflow effects.
[0034] In this solution, after the upper part of the cooking pot liner is cooled, the rice soup foam in the cooking pot cavity will gradually break during the upwelling process. The broken rice soup foam will form condensed water for reflux, and further cool the inner surface of the cooking pot liner when flowing back along the outer surface of the cooking pot cavity, thereby achieving a better cooling effect on the cooking pot liner, achieving a better anti-overflow effect when more rice soup foams break, and at the same time, the condensed water formed after the broken rice soup foam returns will enter between the rice and the inner surface of the cooking pot liner to form a water film, and the water film makes the rice not easily adhere to the inner surface of the cooking pot liner, thereby achieving a better non-sticking effect.
[0035] In this solution, after the lower part of the cooking pot liner is cooled, a water film will be formed at the position where the inner surface of the cooking pot cavity contacts the rice. The water film can better isolate between the rice and the inner surface of the cooking pot liner, thereby making the rice not easily stick to the inner surface of the cooking pot liner and achieving a better non-sticking effect.
[0036] In this solution, during the process of cooking porridge or congee in the rice cooker, the setting of the diversion member enables the air flow to have a larger area to cool the cooking pot liner in different regions. After the cooking pot liner is cooled over a large area, it can better control the full and long-term boiling of the porridge or congee in the cooking pot liner, and it is not easy to have the problem of rice soup foam overflowing during the boiling process, achieving a higher consistency and better taste of the cooked porridge or congee.
[0037] In this solution, the position of the flow port can be set to better divide the air flow into upper and lower regions, thereby achieving better circular flow of the formed air flow along the outer surface of the pot liner to achieve a cooling effect, achieving better improvement in the smoothness of the air flow, and enhancing the cooling effect on the pot liner.
[0038] In this solution, the partial structure settings of the first diversion area and the second diversion area enable more air flow to concentrate on the outer surface of the upper part of the pot liner for cooling, thereby achieving a better anti-overflow effect. At the same time, after the upper part of the pot liner is effectively cooled, it is possible to set the area of the rice and rice soup in the corresponding cooking cavity area of the lower part of the pot liner to be fully boiled, and a better taste of the cooked porridge or congee can be achieved while achieving an effective anti-overflow effect.
[0039] In this solution, the first diversion part, the first blowing port, the second diversion part, and the second blowing port can effectively form the direction of guiding the air flow, achieving better guiding of the air flow to blow onto the pot liner for large-area cooling of the pot liner, with a better overall cooling effect on the pot liner and a simpler structure.
[0040] In this solution, a partition structure can be set. The partition can effectively form an upper air cavity and a lower air cavity. The structures of the upper air cavity and the lower air cavity achieve better formation of two independent regions for cooling the pot liner, thereby achieving better non-stick and anti-overflow effects.
[0041] In this solution, only one air flow device, one flow port, and a diversion part are needed to realize the guiding flow of the air flow in different directions, enabling the air flow to be divided into two parts to respectively blow the air flow towards the upper part and the lower part of the pot liner. The overall structure is simple, the cost is low, and the area of blowing and cooling the pot liner is large, with a better cooling effect.
[0042] In this solution, the structure settings of the pot liner and the placement cavity enable the air flow to flow more smoothly along the gap area between the outer surface of the pot liner and the outer surface of the placement cavity, thereby achieving a better cooling effect on the pot liner.
[0043] In this solution, the position and structural distribution of the anti-overflow sensor can better improve the problem that the rice soup bubbles in the cooking cavity are not easily overflowed. The anti-overflow sensor combines the position of the diversion part to effectively detect the area where the rice soup bubbles are more likely to concentrate, so as to detect the rice soup bubbles more timely, thereby achieving a better anti-overflow effect.
[0044] In this solution, the wind speed of the air flow device can be controlled to increase based on the detection signal of the anti-overflow sensor, so as to achieve a larger and faster air flow to concentrate on cooling the upper part of the pot liner, and then achieve that the rice soup bubbles are more likely to burst to achieve a better anti-overflow effect, effectively preventing the rice soup bubbles in the pot cavity from overflowing.

Detailed Embodiments
[0051] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0052] Embodiment: The rice cooker of the present utility model, as Figures 1 to 5 shown in the composition, is mainly used for cooking rice. Among them, especially for cooking porridge, the cooking effect is good, which can greatly shorten the cooking time of porridge, and at the same time can effectively improve the thickness of the cooked porridge, realizing that during the process of cooking porridge, the rice and rice soup can be fully boiled to form porridge, improving the cooking taste of porridge, and thus effectively improving the user experience effect.
[0053] In the prior art, for the making of porridge, in order to prevent the problem of overflow during the cooking of porridge, mainly to prevent the rice soup from overflowing outside the cooking pot 2, usually a relatively small power is used to control the heating element for heating, so that the rice and rice soup in the cooking pot 2 are in a state of being soaked at a high temperature but not boiling. In this way, the porridge cannot boil effectively during the cooking process for boiling, resulting in a long cooking time for the cooked porridge, generally about two hours. At the same time, the thickness of the cooked porridge is relatively low, the taste of the porridge is relatively poor, and the overall user experience effect is poor.
[0054] The rice cooker of this solution includes a cooker body 1 and a cooking pot 2. A placement cavity 101 is provided on the cooker body 1. The placement cavity 101 is set to have an open structure at the upper part. The cooking pot 2 is set to be removably placed in the placement cavity 101. The cooking pot 2 can be put into the placement cavity 101 or taken out of the placement cavity 101 through the open structure at the upper position of the placement cavity 101. A cooking cavity 201 is provided in the cooking pot 2, and the cooking cavity 201 is mainly used to hold rice and water. Among them, a flow port 102 is also provided on the cooker body 1. The flow port 102 is set to have an open structure and is configured to be connected to the placement cavity 101. The flow port 102 is mainly provided on the wall surface of the placement cavity 101 to form a connection with the placement cavity 101. The air flow outside the placement cavity 101 can enter the placement cavity 101 through the flow port 102. A flow guiding member 3 is provided inside the flow port 102 or on one side of the flow port 102. The flow guiding member 3 can be installed inside the flow port 102 or on one side of the flow port 102, such as the outside or inside of the flow port 102. The flow guiding member 3 is used for the air flow to pass through and is configured to guide the flow direction of the air flow. When the air flow blows into the placement cavity 101 through the flow guiding member 3, the air flow is guided to change the flow direction on the flow guiding member 3, so that the air flow enters the placement cavity 101 in the guided direction, so that the air flow can better blow and cool the cooking pot 2.
[0055] Among them, a first flow guiding area 301 is provided on the flow guiding member 3, and the first flow guiding area 301 is configured to guide the air flow to blow a part of the outer surface of the upper part of the cooking pot 2. The first flow guiding area 301 is provided with a structure for guiding the change of the air flow direction and a structure for the air flow to pass through, so that the air flow is guided to change the direction when passing through the first flow guiding area 301 and blow towards a part of the outer surface of the upper part of the cooking pot 2, thereby realizing the cooling of the upper part of the cooking pot 2, realizing the cooling of the outer surface and the inner surface of the upper part of the cooking pot 2. After the inner surface of the upper part of the cooking pot 2 is cooled, the rice soup bubbles in the cooking cavity 201 can be more easily broken, thereby realizing that the rice soup bubbles will not overflow outside the cooking pot 2, and realizing a better anti-overflow effect during the cooking of porridge or congee.
[0056] Among them, a second flow guiding area 302 is further provided on the flow guiding member 3, and the second flow guiding area 302 is configured to be a structure that guides air flow to blow a part of the outer surface of the lower part of the cooking pot 2. A structure for guiding the change of the air flow direction and a structure for the air flow to pass through are provided on the second flow guiding area 302, so that when the air flow passes through the second flow guiding area 302, the air flow is guided to change its direction and blow towards a part of the outer surface of the lower part of the cooking pot 2, thereby realizing the cooling of the lower part of the cooking pot 2, and realizing the cooling of the outer surface and the inner surface of the lower part of the cooking pot 2. After the inner surface of the lower part of the cooking pot 2 is cooled, condensed water can be generated between the rice in the cooking cavity 201 and the inner surface of the cooking cavity 201. When the condensed water contacts the rice, a dispersed water film is formed, and the water film realizes separating between the rice and the inner surface of the cooking pot 2, and the rice is not easily adhered to the inner surface of the cooking pot 2, thus achieving a better non-sticking effect during the cooking process.
[0057] In this solution, the structure of the flow guiding member 3 realizes that the air flow cools the upper part of the cooking pot 2 upward and the lower part of the cooking pot 2 downward respectively, achieving a large-area air cooling effect on the outer surface of the cooking pot 2 from the upper and lower directions, and further realizing a large-area cooling effect on the inner surface of the cooking pot 2, so as to achieve a better non-sticking effect and a better anti-overflow effect.
[0058] In this solution, for the structure part of the first flow guiding area 301 that guides the air flow direction, a first flow guiding portion 3011 is mainly provided on the first flow guiding area 301, and at least a part of the first flow guiding portion 3011 is set to be a structure that is inclined towards the upper part of the outer surface of the cooking pot 2 in the height direction. When the air flow passes through the first flow guiding area 301, the air flow will contact the outer surface of the first flow guiding portion 3011 and then flow along the inclined direction of the first flow guiding portion 3011, realizing guiding and changing the air flow direction and then blowing out in the inclined direction of the first flow guiding portion 3011. The blown-out air flow forms contact with a part of the outer surface of the upper part of the cooking pot 2, thereby achieving the effect of air cooling the cooking pot 2.
[0059] In this solution, for the structural part of the second flow guiding area 302 to guide the flow direction of the air flow, a second flow guiding part 3021 is mainly arranged on the second flow guiding area 302. At least a part of the second flow guiding part 3021 is arranged in a structure that is inclined towards the lower part position of the outer surface of the pot liner 2 in the height direction. When the air flow passes through the second flow guiding area 302, the air flow will contact the outer surface of the second flow guiding part 3021 and then flow along the inclined direction of the second flow guiding part 3021, so as to realize guiding and changing the flow direction of the air flow and then flowing and blowing out in the inclined direction of the second flow guiding part 3021. The blown-out air flow forms a part that contacts the outer surface of the lower part position of the pot liner 2, thereby achieving the effect of air-cooling and cooling the pot liner 2.
[0060] For the structural part of the pot liner 2, the pot liner 2 has a certain height distance in the vertical direction and is circular in the circumferential direction. The pot liner 2 is divided into an upper part and a lower part by the horizontal plane where the central position of the height distance of the pot liner 2 in the vertical direction is located. The upper part is the upper part position of the pot liner 2, and the lower part is the lower part position of the pot liner 2. Among them, the air flow guided by the first flow guiding area 301 mainly forms a part of the outer surface of the upper part position of the pot liner 2 to be blown, and during the blowing process, the air flow flows at least along the circumferential direction of the pot liner 2 in the horizontal direction. Among them, the outer surface of the placement cavity 101 and the outer surface of the pot liner 2 form a cavity structure for the air flow to flow, so as to realize the effect of the air flow forming a circular surrounding flow on the outer surface of the upper part position of the pot liner 2 in the circumferential direction, and achieve the cooling of the upper part position of the pot liner 2. Among them, the air flow guided by the second flow guiding area 302 mainly forms a part of the outer surface of the lower part position of the pot liner 2 to be blown, and during the blowing process, the air flow flows at least along the circumferential direction of the pot liner 2 in the horizontal direction. Among them, the outer surface of the placement cavity 101 and the outer surface of the pot liner 2 form a cavity structure for the air flow to flow, so as to realize the effect of the air flow forming a circular surrounding flow on the outer surface of the lower part position of the pot liner 2 in the circumferential direction, and achieve the cooling of the lower part position of the pot liner 2.
[0061] In this solution, in order to achieve a better cooling effect to achieve a better anti-overflow effect, the area of the region formed on the first diversion area 301 for the airflow to flow through is set to be larger than the area of the region formed on the second diversion area 302 for the airflow to flow through. In this way, more and larger airflow is blown out through the first diversion area 301, so that the area of the upper part of the cooking pot liner 2 cooled by the airflow is larger and the cooling effect is better. Furthermore, it can better break the rice soup bubbles in the cooking cavity 201. At the same time, after the rice soup bubbles break, water droplets will form and slide down along the inner surface of the cooking pot liner 2. During the sliding process, the water droplets will enter between the inner surface of the cooking pot liner 2 and the rice, so that the rice is not easily adhered to the inner surface of the cooking pot liner 2, achieving a better non-stick effect and a better anti-overflow effect.
[0062] In this solution, in order to achieve a better cooling effect to achieve a better anti-overflow effect, the area of the region formed by the diversion member 3 for the airflow to flow through is set to be A. The area of the region formed on the first diversion area 301 for the airflow to flow through is set to be greater than or equal to two-thirds of A, and the area of the region formed on the second diversion area 302 for the airflow to flow through is set to be less than or equal to one-third of A. In this way, more and larger airflow is blown out through the first diversion area 301, so that the area of the upper part of the cooking pot liner 2 cooled by the airflow is larger and the cooling effect is better. Furthermore, it can better break the rice soup bubbles in the cooking cavity 201 and more rice soup bubbles can be broken. The broken rice soup bubbles can form more water droplets, and the formed water droplets will slide down along the inner surface of the cooking pot liner 2. During the sliding process, the water droplets will enter between the inner surface of the cooking pot liner 2 and the rice, so that the rice is not easily adhered to the inner surface of the cooking pot liner 2, achieving a better non-stick effect and a better anti-overflow effect at the same time.
[0063] In this solution, for the structural part of the airflow cooling the cooking pot liner 2, when the airflow blows onto the cooking pot liner 2 through the first diversion area 301, it is configured to cool a part of the upper part of the cooking pot liner 2, so as to cool the inner surface of the upper part of the cooking pot liner 2. The inner surface of the upper part of the cooking pot liner 2 is the corresponding area on the cavity wall surface of the cooking cavity 201 corresponding to the upper part of the cooking pot liner 2. Cooling the cavity wall surface of the upper part of the cooking cavity 201 can better break the rice soup bubbles in contact with it, and thus achieve a better anti-overflow effect.
[0064] In this solution, for the structural part that cools the cooking pot liner 2 with air flow, when the air flow blows onto the cooking pot liner 2 through the second diversion area 302, it is configured to cool a part of the lower position on the cooking pot liner 2, thereby cooling the inner surface of the lower position on the cooking pot liner 2. The inner surface of the lower position on the cooking pot liner 2 is the area on the cavity wall surface of the cooking cavity 201 corresponding to the lower position on the cooking pot liner 2. Cooling through the cavity wall surface of the lower position on the cooking cavity 201 can better form a water film with the rice, thereby achieving a better non-stick effect.
[0065] In this solution, when the air flow enters between the placement cavity 101 and the outer surface of the cooking pot liner 2 through the first diversion area 301, it cools the upper position on the cooking pot liner 2. When the inner surface of the upper position on the cooking pot liner 2 is cooled, it is configured that the rice soup bubbles in the cooking cavity 201 will burst when they come into contact with the inner surface of the upper position on the cooking pot liner 2. When the upper position on the cooking pot liner 2 is cooled, at this time, the cavity wall surface of the upper position on the cooking cavity 201 corresponding to the upper position on the cooking pot liner 2 will also be cooled, that is, the inner surface of the cooking pot liner 2 is cooled. At this time, when rice and rice soup are being boiled in the cooking cavity 201 and rice soup bubbles are generated, the rice soup bubbles will surge upward along the inner surface of the cooking pot liner 2. When the rice soup bubbles come into contact with the cooled inner surface of the cooking pot liner 2, they will burst due to the temperature difference, thereby preventing the problem of the continuous upward surge and overflow of the rice soup bubbles. After the rice soup bubbles burst, the rice and rice soup can be continuously and fully boiled, and the rice soup bubbles are not easily spilled outside the cooking pot liner 2, achieving a better anti-overflow effect, and at the same time, the cooking effect of porridge or congee is better.
[0066] In this solution, when the air flow enters between the placement cavity 101 and the outer surface of the cooking pot liner 2 through the second diversion area 302, it cools the lower position on the cooking pot liner 2. When the inner surface of the lower position on the cooking pot liner 2 is cooled, it is configured that a water film will be formed on the inner surface of the lower position on the cooking pot liner 2. The water film is located between the rice and the inner surface of the cooking pot liner 2. When the lower position on the cooking pot liner 2 is cooled, at this time, the cavity wall surface of the lower position on the cooking cavity 201 corresponding to the lower position on the cooking pot liner 2 will also be cooled, that is, the inner surface of the cooking pot liner 2 is cooled. At this time, condensed water will be formed on the cavity wall surface of the lower position on the cooking cavity 201. When the condensed water meets the rice, it will disperse to form a gradually spreading water film. The water film separates the cavity wall surface of the lower position on the cooking cavity 201 from the rice, so that the rice is not easily adhered to the inner surface of the cooking pot liner 2, achieving a better non-stick effect, and at the same time, the cooking effect of porridge or congee is better.
[0067] In this solution, in order to make the structure of the air outlet 102 better enable the air flow to form an air flow blowing structure on both the upper and lower positions of the cooking pot 2, at least a part of the air outlet 102 is set above the horizontal plane N where the central position of the height of the cooking pot 2 is located. This is beneficial for the air flow to be divided into two parts from the guide member 3 and form a structure in which two parts blow upward and downward respectively in the vertical direction on the cooking pot 2, thereby realizing a structure for blowing and cooling a large area of the cooking pot 2.
[0068] In this solution, in order to make the structure of the air outlet 102 better enable the air flow to form an air flow blowing structure on both the upper and lower positions of the cooking pot 2, at least a part of the air outlet 102 is set above the horizontal plane N where the central position of the height of the cooking pot 2 is located. This is beneficial for the air flow to be divided into two parts from the guide member 3 and form a structure in which two parts blow upward and downward respectively in the vertical direction on the cooking pot 2. And the height distance H1 from the upper opening 1021 of the air outlet 102 to the horizontal plane N is less than the height distance H2 from the lower opening 1022 of the air outlet 102 to the horizontal plane N. Specifically, the height distance from the upper opening 1021 of the air outlet 102 downward to the horizontal plane N is H1, and the height distance from the lower opening 1022 of the air outlet 102 upward to the horizontal plane N is H2. The height position setting of the air outlet 102 can better define the height position of the guide member 3 in the vertical direction and better set the structure of the guide member 3 to divide the air flow into two parts. One part of the air flow is guided to the vicinity of the top surface of the cooking pot 2 at the upper part of the cooking pot 2 to achieve effective air cooling, which can achieve a better anti-overflow effect and realize guiding the air flow to cool the upper part of the cooking pot 2 quickly and with a shorter flow distance. The other part of the air flow is guided to the lower part of the cooking pot 2 to achieve effective air cooling and a better non-stick effect.

This can better set the structure of the guide member 3 to guide the air flow to the vicinity of the top surface of the cooking pot 2 at the upper part of the cooking pot 2 to achieve an effective air cooling effect.
[0070] In this solution, for the structural part that guides the flow direction of the air flow in the first diversion area 301, a first blowing port 3012 for the air flow to pass through is provided on the first diversion area 301, and the projection area formed by projecting the first blowing port 3012 along the inclined direction of the first diversion part 3011 is configured to overlap with a part of the outer surface of the upper part position on the cooking pot liner 2. The overlapping structure enables the air flow passing through the first blowing port 3012 to contact the outer surface of the upper part position on the cooking pot liner 2 under the guidance of the inclined structure. The first blowing port 3012 is communicated with the flow port 102 and the placement cavity 101. The first blowing port 3012 is located on one side of the first diversion part 3011.

When the air flow passes through the first blowing port 3012, it flows along the inclined direction of the first diversion part 3011, so that when the air flow blows onto the cooking pot liner 2, it contacts a part of the outer surface of the upper part position on the cooking pot liner 2, thereby forming a structure for cooling a part of the upper part position on the cooking pot liner 2.
[0071] And / or, in this solution, for the structural part that guides the flow direction of the air flow in the second diversion area 302, a second blowing port 3022 for the air flow to pass through is provided on the second diversion area 302, and the projection area formed by projecting the second blowing port 3022 along the inclined direction of the second diversion part 3021 is configured to overlap with a part of the outer surface of the lower part position on the cooking pot liner 2. The overlapping structure enables the air flow passing through the second blowing port 3022 to contact the outer surface of the lower part position on the cooking pot liner 2 under the guidance of the inclined structure. The second blowing port 3022 is communicated with the flow port 102 and the placement cavity 101. The second blowing port 3022 is located on one side of the second diversion part 3021. A part of the outer surface of the second diversion part 3021 constitutes the wall of the second blowing port 3022. When the air flow passes through the second blowing port 3022, it flows along the inclined direction of the second diversion part 3021, so that when the air flow blows onto the cooking pot liner 2, it contacts a part of the outer surface of the lower part position on the cooking pot liner 2, thereby forming a structure for cooling a part of the lower part position on the cooking pot liner 2.
[0072] Among them, in order to form a better guiding airflow to blow and cool the cooking pot liner 2, a plurality of first guiding parts 3011 are provided in the first guiding area 301. The plurality of first guiding parts 3011 are all arranged to be inclined towards the upper part position of the outer surface of the cooking pot liner 2 in the height direction to form an inclined structure for guiding the flowing direction of the airflow. The inclined structure can be an inclined plane inclined structure or an arc inclined structure. And the plurality of first guiding parts 3011 are arranged to be spaced apart in the vertical direction. A first blowing port 3012 is formed between two adjacent first guiding parts 3011. The plurality of first blowing ports 3012 form a structure for blowing out a plurality of separated airflow regions. The plurality of first guiding parts 3011 form the first blowing port 3012 between two adjacent first guiding parts 3011. The plurality of first guiding parts 3011 form a plurality of spaced-apart first blowing ports 3012. The plurality of first blowing ports 3012 respectively guide the airflow to flow along the inclined direction. During the guiding process, the airflow is divided into a plurality of separated airflow regions to form a plurality of airflow regions that simultaneously blow onto the upper part position of the cooking pot liner 2, thereby achieving a better air-cooling effect.
[0073] And / or, in order to form a better guiding airflow to blow and cool the cooking pot liner 2, a plurality of second guiding parts 3021 are provided on the second guiding area 302. The plurality of second guiding parts 3021 are all arranged to be inclined towards the lower part position of the outer surface of the cooking pot liner 2 in the height direction to form an inclined structure for guiding the flowing direction of the airflow. The inclined structure can be an inclined plane inclined structure or an arc inclined structure. And the plurality of second guiding parts 3021 are arranged to be spaced apart in the vertical direction. A second blowing port 3022 is formed between two adjacent second guiding parts 3021. The plurality of second blowing ports 3022 form a structure for blowing out a plurality of separated airflow regions. The plurality of second guiding parts 3021 form the second blowing port 3022 between two adjacent second guiding parts 3021. The plurality of second guiding parts 3021 form a plurality of spaced-apart second blowing ports 3022. The plurality of second blowing ports 3022 respectively guide the airflow to flow along the inclined direction. During the guiding process, the airflow is divided into a plurality of separated airflow regions to form a plurality of airflow regions that simultaneously blow onto the lower part position of the cooking pot liner 2, thereby achieving a better air-cooling effect.
[0074] In this solution, in order to better cool the cooking pot liner 2 and thus achieve better non-stick and anti-overflow effects, a partition 103 is further provided on the cooking pot main body 1. The partition 103 is set as a convex structure extending towards the placement cavity 101, mainly convex towards the middle position of the placement cavity 101. When the cooking pot liner 2 is placed in position, the outer surface of the cooking pot liner 2 is configured to be in contact with the partition 103. At this time, the outer surface of the partition 103 contacts the outer surface of the cooking pot liner 2 and forms a contact seal structure, so that the partition 103 divides the placement cavity 101 into an upper air cavity 1011 and a lower air cavity 1012. The upper air cavity 1011 is used for the airflow blown out through the first diversion area 301 to enter, and the lower air cavity 1012 is used for the airflow blown out through the second diversion area 302 to enter, realizing that the airflow blown out through the first diversion area 301 will not directly blow on the airflow blown out through the second diversion area 302, effectively preventing the problem of chaotic airflow caused by the mutual blowing interference between the two parts of the airflow.
[0075] Optionally, the partition 103 is set as an annular structure. The partition 103 forms the placement cavity 101 divided into an upper part and a lower part along the annular outer diameter of the cooking pot liner 2. The upper part is the upper air cavity 1011, and the lower part is the lower air cavity 1012. The upper air cavity 1011 and the lower air cavity 1012 are configured as independent cavity structures. This can prevent the airflow blown out through the first diversion area 301 from mixing and interfering with the airflow blown out through the second diversion area 302 in the placement cavity 101, reducing the interference between these two parts of the airflow. It forms the airflow blown out through the first diversion area 301 to independently air-cool the upper part of the cooking pot liner 2, and forms the airflow blown out through the second diversion area 302 to independently air-cool the lower part of the cooking pot liner 2, realizing a better airflow effect and thus a better cooling effect.
[0076] Specifically, in this solution, the outer surface of the upper part of the cooking pot liner 2, the partition part 103, and the outer surface of the upper part of the placement cavity 101 together constitute the upper air cavity 1011. And it is set that the air flow blown out through the first diversion area 301 enters the upper air cavity 1011 to cool the upper part of the cooking pot liner 2. That is, the partition part 103, the outer surface of the upper part of the cooking pot liner 2, and the outer surface of the upper part of the placement cavity 101 together constitute the cavity structure of the upper air cavity 1011. The upper air cavity 1011 is connected to the first diversion area 301, or the upper air cavity 1011 is directly connected to the first blowing port 3012. The partition part 103 is the bottom wall of the upper air cavity 1011, the outer surface of the upper part of the cooking pot liner 2 constitutes the inner side wall of the upper air cavity 1011, and the outer surface of the upper part of the placement cavity 101 constitutes the outer side wall of the upper air cavity 1011, so as to form the upper air cavity 1011 for the air flow to enter. The air flow enters the upper air cavity 1011 and flows along the outer surface of the upper part of the cooking pot liner 2 in the vertical direction and on the circumference in the circumferential direction, realizing the large-area air-cooling effect on the outer surface of the upper part of the cooking pot liner 2.
[0077] Specifically, in this solution, the outer surface of the lower part of the cooking pot liner 2, the partition part 103, and the outer surface of the lower part of the placement cavity 101 together constitute the lower air cavity 1012. And it is set that the air flow blown out through the second diversion area 302 enters the lower air cavity 1012 to cool the lower part of the cooking pot liner 2. That is, the partition part 103, the outer surface of the lower part of the cooking pot liner 2, and the outer surface of the lower part of the placement cavity 101 together constitute the cavity structure of the lower air cavity 1012. The lower air cavity 1012 is connected to the second diversion area 302, or the lower air cavity 1012 is directly connected to the second blowing port 3022. The partition part 103 is the top wall of the lower air cavity 1012, the outer surface of the lower part of the cooking pot liner 2 constitutes the inner side wall of the lower air cavity 1012, and the outer surface of the lower part of the placement cavity 101 constitutes the outer side wall of the lower air cavity 1012, so as to form the lower air cavity 1012 for the air flow to enter. The air flow enters the lower air cavity 1012 and flows along the outer surface of the lower part of the cooking pot liner 2 in the vertical direction and on the circumference in the circumferential direction, realizing the large-area air-cooling effect on the outer surface of the lower part of the cooking pot liner 2.
[0078] It can be understood that the placement cavity 101 is also correspondingly divided into an upper part and a lower part. The placement cavity 101 can be divided into upper and lower parts by using the horizontal plane where the central position of the placement cavity 101 is located in the vertical direction as the division. The upper part is the upper part of the placement cavity 101, and the lower part is the lower part of the placement cavity 101, so as to form the specific structure of the placement cavity 101.
[0079] In this solution, in order to improve the outer surface of the cooking pot liner 2 to form a better guiding airflow to flow along the outer surface of the cooking pot liner 2 and thus achieve a better cooling effect, a part of the outer surface at the upper part of the cooking pot liner 2 is set to be an arc-shaped structure that gradually inclines upward towards the central axis M of the cooking cavity 201 in the height direction, so that the annular outer diameter at the upper part of the cooking pot liner 2 is a structure that gradually shrinks from low to high. The cooking pot liner 2 is a circular structure in the annular direction. By setting an arc-shaped structure that gradually inclines in the vertical direction, the annular outer diameter formed by the upper part of the cooking pot liner 2 on the circumference is a structure that gradually shrinks from low to high, so as to achieve better movement of the airflow along the outer surface of the cooking pot liner 2 on the outer surface of the cooking pot liner 2. Among them, when the airflow passing through the first diversion area 301 blows onto the cooking pot liner 2, a part of the airflow flows along the arc-shaped inclined structure of the cooking pot liner 2 in the vertical direction to cool the cooking pot liner 2, and a part of the airflow flows around the outer diameter circumference of the cooking pot liner 2 in the annular direction of the cooking pot liner 2 to achieve cooling of the entire area of the cooking pot liner 2 in the annular outer diameter direction, realizing the effect of large-area cooling of the upper part of the cooking pot liner 2. At the same time, the gradual shrinkage from low to high is conducive to the airflow concentrating on the area with a relatively small outer diameter at the upper part of the cooking pot liner 2, so as to form airflow concentration to cool this area, which is conducive to the rice soup bubbles in the cooking cavity 201 to burst concentratedly at the area in the cooking cavity 201 corresponding to this area, and thus achieve a better anti-overflow effect.
[0080] And / or, in order to improve the outer surface of the pot liner 2 to form a better guiding airflow to flow along the outer surface of the pot liner 2 and thus achieve a better cooling effect, a part of the outer surface at the lower part of the pot liner 2 is set in the height direction to be an arc-shaped structure gradually inclined downward toward the central axis M of the pot cavity 201, so that the annular outer diameter at the lower part of the pot liner 2 is a structure gradually shrinking from high to low. The pot liner 2 is a circular structure in the circumferential direction. By setting an arc-shaped structure gradually inclined in the vertical direction, the annular outer diameter formed by the lower part of the pot liner 2 on the circumference is a structure gradually shrinking from high to low, so as to achieve better movement of the airflow along the outer surface of the pot liner 2 on the outer surface of the pot liner 2. Among them, when the airflow passing through the second flow guiding area 302 blows onto the pot liner 2, a part of the airflow flows along the arc-shaped inclined structure of the pot liner 2 in the vertical direction to cool the pot liner 2, and a part of the airflow flows in the circumferential direction of the pot liner 2 along the outer diameter circumference of the pot liner 2 to achieve cooling of the entire area of the pot liner 2 in the annular outer diameter direction, achieving the effect of large-area cooling of the lower part of the pot liner 2. At the same time, gradually shrinking from high to low is conducive to the airflow to concentrate and flow toward the area near the bottom of the pot liner 2, which is conducive to better cooling of the bottom of the pot liner 2 and the area near the side connected to the bottom, effectively preventing the problem of sticking to the pot at the bottom position of the pot liner 2 and the area near the bottom on the side position, and thus achieving a better non-stick effect.
[0081] The rice cooker of this solution further includes a pot lid 4. The pot lid 4 is configured to be rotatably swingable relative to the pot body 1. The opening and closing structure of the cooking cavity 201 of the inner pot 2 is realized through the pot lid 4, that is, when the pot lid 4 rotates, the cooking cavity 201 can be in an open structure, and when the pot lid 4 rotates in the opposite direction again, the cooking cavity 201 can be in a closed structure. At this time, the pot lid 4 covers the upper part of the inner pot 2. Among them, in order to achieve a better anti-overflow effect, an anti-overflow sensor 401 is provided on the pot lid 4. The anti-overflow sensor 401 is configured to protrude toward the bottom wall of the cooking cavity 201 at the end face position of the pot lid 4, and a part of the anti-overflow sensor 401 is located inside the cooking cavity 201. The end position of the anti-overflow sensor 401 is located in the corresponding area position in the upper part of the inner pot 2 inside the cooking cavity 201. That is, the cooking cavity 201 can also be correspondingly divided into an upper part position and a lower part position with the inner pot 2. The upper part position of the cooking cavity 201 corresponds to the upper part position of the inner pot 2, and the lower part position of the cooking cavity 201 corresponds to the lower part position of the inner pot 2. The end position of the anti-overflow sensor 401 is located in the upper part position area of the cooking cavity 201 to form a structure extending into the cooking cavity 201, and at the same time, it can prevent the end position of the anti-overflow sensor 401 from extending too deep into the cooking cavity 201. The end position of the anti-overflow sensor 401 is not located in the lower part position of the cooking cavity 201, so that the anti-overflow sensor 401 can effectively detect the rice soup bubbles surging in the cooking cavity 201 and achieve a better anti-overflow effect.
[0082] Among them, the end position of the anti-overflow sensor 401 is set above the first diversion area 301. At this time, the anti-overflow sensor 401 can more easily detect and sense the surging rice soup bubbles, achieving a better anti-overflow effect; and / or, among them, the distance L1 from the end position of the anti-overflow sensor 401 along the horizontal direction to the inner surface of the inner pot 2 on the side close to the flow guide member 3 is greater than the distance L2 from the end position of the anti-overflow sensor 401 along the horizontal direction to the inner surface of the inner pot 2 on the side opposite to the position of the flow guide member 3. At this time, the end position of the anti-overflow sensor 401 is relatively far from the flow guide member 3 in the cooking cavity 201, that is, relatively far from the flow port 102, that is, relatively far from the position on the inner pot 2 where the wind flowing out from the flow guide member 3 first blows.
[0083] It can be understood that when the air flow is blown onto the cooking pot liner 2 through the air guiding member 3, the air flow gradually forms a cooling effect on the cooking pot liner 2. At this time, the position on the cooking pot liner 2 that is relatively close to the air guiding member 3 has a relatively better cooling effect by the air flow. As the air flow gradually flows, the flowing air flow will be heated by the heat on the cooking pot liner 2, and the air flow will be slowly heated to form warm air with a certain temperature during the movement. This results in a relatively poor cooling effect on the position of the cooking pot liner 2 that is far from the air guiding member 3. Then, the rice soup bubbles in the cooking cavity 201 are more likely to burst and thus less likely to overflow from the cooking pot liner 2 near the position close to the air guiding member 3, while the rice soup bubbles in the cooking cavity 201 are less likely to burst and thus more likely to overflow from the cooking pot liner 2 near the position far from the air guiding member 3. In this solution, by setting the end position of the anti-overflow sensor 401 at a position in the cooking cavity 201 that is relatively far from the air guiding member 3, it constitutes that the end position of the anti-overflow sensor 401 is set at a position in the cooking cavity 201 where the rice soup bubbles are not easy to burst and are more likely to overflow. Thus, it can more timely and effectively detect the surging rice soup bubbles, so as to timely control the cooking parameters of the rice cooker, such as the state of the heating element, the magnitude of the wind speed through the air guiding member 3, etc., to achieve a better anti-overflow effect, and achieve timely and effective reduction of rice soup bubbles or making more rice soup bubbles burst.
[0084] In this solution, the anti-overflow sensor 401 is electrically connected to the control module, and an air flow device is provided outside the air guiding member 3 to provide air flow, and the air flow device is also electrically connected to the control module. The control module controls the working state of the air flow device, such as starting to work, stopping working, increasing power to work or decreasing power to work. The air flow generated by the air flow device can be blown onto the cooking pot liner 2 through the flow port 102 and the air guiding member 3. At the same time, the anti-overflow sensor 401 is also electrically connected to the control module, so that when the anti-overflow sensor 401 detects the rice soup bubbles, it can feedback the detection information into the control module. The control module can control the working states of the heating element and the air flow device based on the detection information of the anti-overflow sensor 401. Among them, the control module is set to at least increase the wind speed of the air flow device when the anti-overflow sensor 401 is triggered by the rice soup bubbles to send a signal. When the anti-overflow sensor 401 is triggered by the rice soup bubbles to send a signal, it indicates that the rice soup bubbles in the cooking cavity 201 have surged to contact the end position of the anti-overflow sensor 401. At this time, the control module controls the wind speed of the air flow device to increase, which can form a better cooling effect on the cooking pot liner 2, and thus more rice soup bubbles burst, and thus achieve a better anti-overflow effect.
[0085] Optionally, the air flow device is set as a blower, and the air flow generated by the air flow device mainly blows onto the outer surface of the cooking pot liner 2 through the air guiding member 3 and the flow port 102, so as to achieve the cooling effect on the cooking pot liner 2.
[0086] In this solution, a heating element is provided for heating the cooking pot liner 2. The heating element is electrically connected to the control module, and the control module controls the start or stop of the heating element, controls the increase or decrease of the heating power, and simultaneously controls the working state of the heating element based on the detection signal of the anti-overflow sensor 401.
[0087] Optionally, in this solution, when the anti-overflow sensor 401 is triggered by rice soup to generate a signal, the heating power of the heating element can also be controlled to decrease at this time, or the heating element can be controlled to stop heating, so as to achieve the effect of intermittently boiling rice and rice soup, and can also effectively prevent the rice soup in the cooking cavity 201 from overflowing, achieving a better anti-overflow effect.
[0088] Optionally, in this solution, the shape of the placement cavity 101 is roughly the same as that of the cooking pot liner 2, but there is a certain gap between the outer surface of the placement cavity 101 and the outer surface of the cooking pot liner 2. This gap facilitates the user to place the cooking pot liner 2 into the placement cavity 101. This gap is the cavity part that constitutes the upper air cavity 1011 and the lower air cavity 1012. At the same time, this gap can be used for air flow to flow between the outer surface of the placement cavity 101 and the cooking pot liner 2, so as to achieve the effect of air-cooling the cooking pot liner 2.
[0089] Optionally, an exhaust port is provided on the cooking pot main body 1 in this solution. The position of the exhaust port can be set opposite to the position of the flow port 102. One end of the exhaust port is connected to the placement cavity 101, and the other end of the exhaust port is connected to the outside of the cooking pot main body 1, so that the air flow is discharged outward through the exhaust port after air-cooling the cooking pot liner 2.
[0090] In this solution, the parts not described can be implemented by adopting or referring to the prior art.
[0091] Working principle: For the rice cooker in this solution, during the cooking process, it can be controlled to start the air flow device to work. The air flow device generates air flow, and the air flow blows out from the first diversion area 301 and the second diversion area 302 respectively. The air flow passing through the first diversion area 301 blows a part of the upper part of the inner surface of the cooking pot 2 for air-cooling and temperature reduction, and the air flow passing through the second diversion area 302 blows a part of the lower part of the inner surface of the cooking pot 2 for air-cooling and temperature reduction. Among them, after the outer surface and the inner surface of the lower part of the cooking pot 2 are cooled, condensed water will be generated between the inner surface and the rice, and the condensed water forms a water film. The water film relatively isolates the rice from the outer surface of the cooking pot 2, making it difficult for the rice to stick to the inner surface of the cooking pot 2, and a better non-stick effect can be achieved. At the same time, after the outer surface and the inner surface of the upper part of the cooking pot 2 are cooled, when there are rice soup bubbles generated in the cooking cavity 201, the rice soup bubbles will surge up and contact the inner surface of the upper part of the cooking pot 2. At this time, because the temperature of this inner surface is reduced, the rice soup bubbles will form an effect of being more easily broken when contacting this inner surface. After the rice soup bubbles break, the number of surging rice soup bubbles will decrease, thereby achieving a better anti-overflow effect. It is realized that during the process of cooking dry rice, porridge or congee, the heating element can be heated at high power for a long time, so that the rice surges and boils in the rice soup and is not easy to overflow the pot. Furthermore, it can effectively shorten the cooking time of the rice cooker for cooking porridge and congee. At the same time, a better cooking effect can be achieved, such as a higher consistency of the cooked porridge and congee, thereby improving the user experience of the rice cooker.

In actual applications, various changes can be made in form and details without departing from the spirit and scope of the present invention, and all are within the protection scope of the present invention.
