Description

Technical Field

[0001] This utility model relates to the field of kitchen appliances, specifically to a cooking device. Background Technology

[0002] Existing cooking appliances, such as rice cookers and electric pressure cookers, mainly use fans to cool the inner pot in order to achieve better non-stick rice. They mainly use independent fans to cool the inner pot and the control board. This requires multiple fans to provide airflow, resulting in a complex internal structure and high cost. In addition, multiple fans also lead to high maintenance costs and poor cooling effect on the inner pot. Utility Model Content

[0003] The present invention aims to at least partially solve one of the technical problems in the aforementioned related technologies.

[0004] Therefore, the purpose of this utility model is to provide a cooking device that mainly solves the problem of existing cooking devices requiring multiple fans for cooling, and further solves the problem of poor cooling effect on the inner pot.

[0005] The present invention provides a cooking device, including a pot body and a pot inner pot. The pot body is provided with a pot cavity and a heating element. The pot inner pot is located inside the pot cavity, and the heating element is located inside the pot cavity to heat the pot inner pot. The pot body is provided with a control board assembly, and the control board assembly is provided with a radiator. The pot body is also provided with an airflow component, which is used to provide airflow to cool the pot inner pot or the radiator.

[0006] The pot body is also provided with a switching component, which includes a switching element. The switching element is configured as a rotatable structure so that the switching element can be located in a first position or in a second position.

[0007] When the switching element is in the first position, it is configured such that the airflow element is connected to the outer wall surface of the pot, thereby forming a structure in which the airflow provided by the airflow element can flow to the outer wall surface of the pot to cool the pot.

[0008] When the switching element is in the second position, it is configured such that the airflow element is connected to the outer wall surface of the radiator, thereby forming a structure in which the airflow provided by the airflow element can flow to the outer wall surface of the radiator to cool the radiator.

[0009] The aforementioned cooking device is configured such that when the switching element is in the first position, the airflow element and the outer wall surface of the radiator are not connected, so that the airflow element is configured to cool only the inner pot.

[0010] When the switching element is in the second position, it is configured such that the airflow element and the outer wall surface of the pot are not connected, so that the airflow element is configured to cool only the radiator.

[0011] In the aforementioned cooking device, a main air duct is provided on one side of the airflow component, a first air duct is provided on the pot cavity, and a second air duct is provided on one side of the radiator. When the switching component is in the first position, the main air duct and the first air duct are connected to each other so that the airflow can flow from the position of the airflow component to the position of the pot cavity. At this time, the main air duct and the second air duct are not connected to each other so that the switching component forms a structure that blocks the airflow to the radiator.

[0012] In the aforementioned cooking device, when the switching element is in the second position, the main air duct and the second air duct are connected to each other so that airflow can flow from the airflow element position to the radiator position. At this time, the main air duct and the first air duct are not connected to each other so that the switching element forms a structure that blocks the airflow to the inner pot.

[0013] The aforementioned cooking device includes a spacer formed between the outer wall surface of the inner wall of the pot and the inner wall surface of the pot cavity, which is connected to a first air duct for airflow. The spacer is configured to cool the inner wall of the pot when airflow enters the spacer from the first air duct and flows through it.

[0014] The aforementioned cooking device also includes an air outlet on the pot cavity for airflow to be discharged toward the outside of the pot cavity. At least a portion of the air outlet is located above the first air duct, and the positions of the air outlet and the first air duct are relatively distributed in the radial direction of the pot cavity.

[0015] The aforementioned cooking device also includes a ring-shaped sealing part inside the pot cavity. The sealing part is configured to be a protruding structure facing the outer wall surface of the pot to form a sealing structure that is in contact with the outer wall surface of the pot.

[0016] The first air duct is positioned below the partition section to connect with the partition section, thus creating a structure where the airflow enters the partition section below the partition section and cools the outer wall surface of the inner pot located below the partition section.

[0017] In the aforementioned cooking device, the inner wall surface of the pot pot is provided with a water level mark A and a water level mark B for marking the water level position, with water level mark A positioned above water level mark B.

[0018] The water level indicator A is positioned above the center of the vertical distance of the inner pot and below two-thirds of the vertical distance of the inner pot from bottom to top.

[0019] Furthermore, the vertical height of the partition is located below the water level indicator A and above the water level indicator B.

[0020] The aforementioned cooking device is configured such that when the heating element is configured to heat the inner pot, the switching element is positioned in a second position, and when the heating element is configured not to heat the inner pot, the switching element is positioned in a first position.

[0021] The aforementioned cooking device is configured such that the control panel assembly is electrically connected to the heating element, the airflow element, and the switching element;

[0022] The control panel assembly is at least used to cause the switching assembly to operate when the heating element stops working, rotating the switching element to a first position and causing the airflow element to operate to generate airflow to cool the inner pot; or, the control panel assembly is at least used to cause the switching assembly to operate when the heating element is working, rotating the switching element to a second position and causing the airflow element to operate to generate airflow to cool the radiator.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] In this solution, the switching component can switch the switching element between the first and second positions, thereby enabling each airflow element to independently cool the inner pot or radiator with full airflow force. The airflow will not be dispersed, resulting in better heat dissipation for the inner pot or radiator.

[0025] The switching mechanism in this design allows the airflow component to not only independently cool the inner pot of the rice cooker, but also to independently cool the radiator, achieving better cooling for both the radiator and the inner pot, thus resulting in better non-stick rice.

[0026] In this solution, only a single airflow component is needed to independently cool the inner pot or the radiator, eliminating the need for multiple fans for separate cooling. The overall structure is simpler, the cost is lower, and it also solves the problem of poor cooling performance caused by dispersed airflow.

[0027] In this solution, the airflow component has a multi-functional effect, achieving high utilization rate. There is no need to set up multiple fans. A single airflow component can not only independently cool the inner pot, but also independently cool the radiator. Both achieve a concentrated cooling effect of full airflow force, and the airflow will not be dispersed. It is low in cost and has a good cooling effect.

[0028] The switching component in this design can effectively rotate, such as by oscillating, to switch the airflow path. This means that the switching component can switch between the first and second positions, thereby changing the direction of the airflow path. The overall structure is simple. By combining the main air duct, the first air duct, and the second air duct, the airflow direction can be effectively switched and changed. This allows the airflow to be concentrated and independently cooled on the inner pot or radiator without being dispersed, resulting in better cooling performance.

[0029] The structural positioning of the first air duct and the exhaust port in this design enables the airflow to achieve a large-area cooling effect within the partition, allowing the airflow to concentrate on cooling the inner pot before being discharged, thereby improving the cooling effect on the inner pot.

[0030] In this design, the combination of the partition and sealing sections limits the space for rice to be placed on the inner pot by restricting the airflow area, rather than cooling the entire inner pot. This allows the airflow to be concentrated on cooling the area below the sealing section of the inner pot, resulting in better centralized cooling and a better non-stick rice effect.

[0031] In this solution, when the heating element is working, it cools the radiator without cooling the inner pot, thereby reducing the impact of airflow on the heating efficiency of the inner pot, improving the cooling effect of the radiator, and enhancing the stability of the control board assembly.

[0032] In this solution, the inner pot is cooled when the heating element is not working, instead of cooling the radiator. This achieves a large-area, full-force concentrated cooling effect within the partition, resulting in better cooling of the inner pot and thus better non-stick properties for the rice.

Detailed Implementation

[0037] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0038] Example: A cooking device of this utility model, such as... Figures 1 to 3 As shown in the diagram, the structure of the cooking device allows for better cooling of the inner pot 2, resulting in better non-stick performance when cooking rice. At the same time, the airflow component 102 can be used for multiple functions, not only to cool the inner pot 2 but also to cool the radiator 401. This results in better cooling performance and lower cost.

[0039] This solution provides a cooking device, including a pot body 1 and a pot inner 2. The pot inner 2 is used to hold rice and water for cooking. The pot body 1 is provided with a pot cavity 101 and a heating element 5. The pot inner 2 is located inside the pot cavity 101. The user can manually place the pot inner 2 into or remove it from the pot cavity 101. The heating element 5 is located inside the pot cavity 101 to heat the pot inner 2. After the pot inner 2 is heated, it cooks the rice. A control board assembly 4 is provided inside the pot body 1. The control board assembly 4 includes a control board and components. A radiator 401 is provided on the control board assembly 4. This is used to dissipate heat from some components on the control board assembly 4, ensuring stable operation of the control board assembly 4. Simultaneously, an airflow component 102 is also provided inside the pot body 1. The airflow component 102 provides airflow to cool the inner pot 2 or the radiator 401. The airflow component 102 does not simultaneously cool both the inner pot 2 and the radiator 401; instead, the control board assembly 4 can indirectly control the direction of the airflow path of the airflow component 102, thereby enabling the airflow component 102 to independently cool the inner pot 2 or independently cool the radiator 401. This allows for relatively concentrated airflow. The airflow will not disperse, resulting in a better cooling effect. Specifically, in terms of structure, a switching component 3 is also provided inside the pot body 1. The switching component 3 includes at least a switching element 301. The switching element 301 is configured to be rotatable, allowing it to be positioned in a first position or a second position. The switching element 301 is mainly configured to rotate and swing under the control of the control board component 4. This rotational and swinging motion allows for switching between the first and second positions, changing the current position of the switching element 301, thereby altering the airflow. The path direction is mainly formed to guide the airflow or to block the airflow. The first position and the second position are different positions so as to switch the airflow to flow in different directions. Specifically, when the switching member 301 is in the first position, it is configured to connect the airflow member 102 with the outer wall surface of the pot 2, thereby forming a structure in which the airflow provided by the airflow member 102 can flow to the outer wall surface of the pot 2 to cool the pot 2. At this time, the switching member 301 is in the first position to guide the airflow toward the pot 2 to achieve the cooling effect of the pot 2.When the switching element 301 is in the second position, it forms a structure in which the airflow element 102 is connected to the outer wall surface of the radiator 401, thereby allowing the airflow provided by the airflow element 102 to flow to the outer wall surface of the radiator 401 to cool the radiator 401. In this second position, the switching element 301 guides the airflow towards the radiator 401 to achieve a cooling effect. Therefore, the switching component 3 can switch the switching element 301 between the first and second positions, allowing a single airflow element 102 to independently cool the inner pot 2 or the radiator 401 with full airflow. The airflow will not be dispersed; only a single airflow element 102 is needed to independently cool the inner pot 2 or the radiator 401, eliminating the need for multiple fans for separate cooling. The overall structure is simpler, the cost is lower, and it also solves the problem of poor cooling effect caused by dispersed airflow.

[0040] As can be seen, the airflow component 102 of this solution has a multi-functional effect, achieving high utilization of the airflow component 102. There is no need to set up multiple fans. A single airflow component 102 can not only independently cool the inner pot 2, but also independently cool the radiator 401. In both cases, it achieves a concentrated cooling effect of full airflow force, the airflow will not be dispersed, the cost is low and the cooling effect is good.

[0041] In this solution, the airflow provided by the airflow component 102 can achieve a centralized cooling effect. The airflow is not easily dispersed or lost. Specifically, when the switching component 301 is in the first position, the airflow component 102 is configured to be disconnected from the outer wall surface of the radiator 401, thus enabling the airflow component 102 to cool only the inner pot 2. In this first position, the switching component 301 connects the airflow component 102 to the outer wall surface of the inner pot 2 but disconnects it from the outer wall surface of the radiator 401. This ensures that the airflow flows concentratedly towards the inner pot 2, rather than dispersing towards the radiator 401, achieving a concentrated airflow flow. The airflow can then be directed towards the inner pot 2 to achieve a centralized cooling effect. Furthermore, when the switching component 301 is in the second position, the airflow component 102 is configured to be disconnected from the outer wall surface of the inner pot 2, thus enabling the airflow component 102 to cool only the radiator 401. In this structure, the switching element 301 is positioned in the second position so that the airflow element 102 is connected to the outer wall surface of the radiator 401 but not connected to the outer wall surface of the inner pot 2. This ensures that the airflow can only flow in a concentrated manner towards the radiator 401, rather than being dispersed towards the inner pot 2. This guides the concentrated flow of airflow, allowing it to be directed towards the radiator 401 for concentrated cooling. Therefore, the structure of the switching element 301 in this solution guides the airflow for concentrated flow, preventing airflow dispersion. Furthermore, only a single airflow element 102 is needed to independently cool either the inner pot 2 or the radiator 401 without dispersing the airflow. The airflow can be concentrated to cool either the inner pot 2 or the radiator 401 separately. This simplifies the overall structure, reduces costs, and effectively solves the problem of high maintenance costs caused by multiple airflow elements 102.

[0042] In this design, a main air duct 103 is provided on one side of the airflow component 102, primarily located above the airflow. When the airflow component 102 starts operating, it generates airflow that blows upwards into the main air duct 103. Simultaneously, a first air duct 104 is provided on the cavity 101, primarily located on the side of the cavity 101 near the airflow component 102. The first air duct 104 forms a through-structure connecting the outer and inner wall surfaces of the cavity 101. A second air duct 10 is also provided on one side of the radiator 401. 5. A second air duct 105 is provided on the side of the radiator 401 near the airflow component 102 to form an airflow path. The switching component 301 is located between the first air duct 104 and the second air duct 105. The rotational swinging motion of the switching component 301 can realize the blocking structure of the first air duct 104 or the second air duct 105. In turn, the direction of the airflow path can be changed by the switching component 301. That is, the airflow can be switched to flow towards the inner pot 2 to cool the inner pot 2, or it can be switched to flow towards the radiator 401 to cool the radiator 401.

[0043] When the switching element 301 is in the first position, the main air duct 103 and the first air duct 104 are connected to allow airflow from the airflow element 102 to the inner pot 2. At this time, the main air duct 103 and the second air duct 105 are not connected, causing the switching element 301 to block airflow to the radiator 401. When the switching element 301 rotates and swings to the first position, it forms a shielding structure for the second air duct 105, thus blocking the main air duct 103 and the second air duct 105, creating a non-connected structure. The main air duct 103 and the first air duct 104 are connected because there is no obstruction from the switching element 301. When the airflow element 102 starts working, the airflow... The airflow can be directed from the main air duct 103 to the first air duct 104, and then through the first air duct 104 into the partition 106, and finally blown towards the inner pot 2, thereby cooling the inner pot 2 and improving the non-stick effect of the rice. At the same time, because the switching component 301 blocks the second air duct 105, the airflow will not be dispersed, and the airflow will be concentrated and enter the first air duct 104. The switching component 301 blocks the airflow from flowing towards the radiator 401 and guides the airflow towards the inner pot 2, thereby cooling the inner pot 2 without cooling the radiator 401. This concentrated airflow cools the inner pot 2 better, making it less likely for the rice to stick to the inner wall surface of the inner pot 2, resulting in a better non-stick effect for the rice.

[0044] When the switching element 301 is in the second position, the main air duct 103 and the second air duct 105 are connected to allow airflow from the airflow element 102 to the radiator 401. At this time, the main air duct 103 and the first air duct 104 are not connected, causing the switching element 301 to block airflow to the inner pot 2. When the switching element 301 rotates and swings to the second position, it forms a shielding structure against the first air duct 104, thus blocking the main air duct 103 and the first air duct 104, creating a non-connected structure. The main air duct 103 and the second air duct 105 are connected because there is no obstruction from the switching element 301. At this time, when the airflow element... When 102 starts working, the airflow can be blown from the main air duct 103 to the second air duct 105, and then blown towards the radiator 401 through the second air duct 105, thereby cooling the radiator 401 and improving the working stability and reliability of the control board assembly 4. At the same time, because the switching component 301 blocks the first air duct 104, the airflow will not be dispersed, and the airflow will be concentrated into the second air duct 105. The switching component 301 blocks the airflow from flowing towards the inner pot 2 and guides the airflow towards the radiator 401, thereby cooling the radiator 401 without cooling the inner pot 2. This concentrates the airflow to cool the radiator 401, resulting in a better cooling effect for the radiator 401.

[0045] The switching component 3 of this solution also includes a motor, which is electrically connected to the control board component 4. The control board component 4 controls the working state of the switching component 3 mainly by controlling the working state of the motor. By controlling the forward or reverse rotation of the motor, the motor drives the switching component 301 to rotate and swing, so that the motor drives the switching component 301 to rotate and swing from the first position to the second position, and so on, so that the motor drives the switching component 301 to rotate and swing from the second position to the first position. This achieves the structure of switching component 301 switching between the first position and the second position, thereby changing the direction of the airflow path through the switching component 301, that is, switching the connection or disconnection between the main air duct 103 and the first air duct 104 and between the main air duct 103 and the second air duct 105; thereby achieving the cooling of the inner pot 2 by the airflow, or the cooling of the radiator 401 by the airflow.

[0046] The switching component 3 can also be equipped with a transmission structure, which can be equipped with a transmission wheel or pulley. The motor is connected to the transmission structure, and the transmission structure is connected to the switching component 301. The motor drives the transmission structure to rotate and swing the switching component 301, thereby enabling the switching component 301 to switch positions between the first position and the second position.

[0047] In this design, the structure for cooling the outer surface of the inner pot 2 using airflow includes a spacer 106 formed between the outer surface of the inner pot 2 and the inner surface of the pot cavity 101, which is connected to the first air duct 104. This spacer 106 allows airflow to pass through without direct contact between the outer surface of the inner pot 2 and the inner surface of the pot cavity 101. The spacer 106 creates a space for airflow, and when airflow enters the spacer 106 from the first air duct 104... When the airflow passes through the partition 106, it forms a structure that cools the inner pot 2. The airflow enters the partition 106 through the first air duct 104 and flows within the partition 106 to form an airflow on the outer wall surface of the inner pot 2, thereby cooling the outer wall surface of the inner pot 2 and thus cooling the inner wall surface of the inner pot 2. This allows the rice flour to cool and form a water film at the contact point with the inner wall surface of the inner pot 2, making it less likely for the rice to stick to the inner wall surface of the inner pot 2, thus achieving a better non-stick effect for the rice.

[0048] The spacer 106 is configured as an air-proof structure to allow airflow. The spacer 106, together with the inner wall surface of the pot cavity 101 and the outer wall surface of the pot 2, forms a space area for airflow, thereby achieving a cooling effect on the pot 2 when the airflow flows.

[0049] In this design, to further enhance the effect of concentrated cooling of the inner pot 2 by airflow, an air outlet 108 is provided on the pot cavity 101 for airflow to be discharged outwards. After the airflow enters the partition 106 and cools the inner pot 2 over a large area, it can be discharged outwards through the air outlet 108. This achieves the effect of airflow entering and exiting the partition 106. The main structure is that at least a portion of the air outlet 108 is located above the first air duct 104, so that the airflow can better flow and cool the inner pot 2 along the radial annular direction of the partition 106 and on the bottom wall and vertical arc surface of the inner pot 2. This allows the airflow to fully flow and cover the outer wall surface of the inner pot 2 for cooling, achieving the goal of cooling the bottom surface of the inner pot 2. The airflow can continuously flow upwards to cool the vertical curved surface area of ​​the inner pot 2, thereby achieving a large-area cooling effect and reducing blind spots in the airflow cooling of the inner pot 2. At the same time, the airflow will generate hot airflow during the cooling process of the inner pot 2. By placing part or all of the air outlet 108 above the first air duct 104, the hot airflow can be better discharged. Furthermore, the positions of the air outlet 108 and the first air duct 104 are relatively distributed in the radial direction of the inner pot 2. This relatively distributed structure allows the airflow to cover a larger area of ​​the outer wall surface of the inner pot 2 for cooling before being discharged through the air outlet 108. This can effectively reduce blind spots in the airflow cooling of the inner pot 2, improve the effect of concentrated cooling of the inner pot 2, and thus achieve a better non-stick effect for rice.

[0050] In this design, to further enhance the effect of concentrated cooling of the inner pot 2 by airflow, a ring-shaped sealing part 107 is provided inside the pot cavity 101. The sealing part 107 forms a complete ring structure around the ring direction of the pot cavity 101, that is, around the ring direction of the inner pot 2. At the same time, the sealing part 107 is configured to be a protruding structure facing the outer wall surface of the inner pot 2, thus forming a sealing structure that is in contact with the outer wall surface of the inner pot 2. When the inner pot 2 is placed inside the pot cavity 101... At this time, the outer wall surface of the inner pot 2 and the side wall surface of the partition 107 in the convex direction come into contact with each other to form a sealing structure. Under this sealing structure, the airflow will not pass through or flow through the partition 107 after entering the partition 106, that is, the airflow will not enter the upper area of ​​the partition 107. This achieves the goal of confining the airflow to the space area below the partition 107 to centrally cool and lower the outer wall surface of the area where the rice is placed in the inner pot 2. At the same time, the first air duct 104 is provided. The position connecting to the partition 106 is located below the sealing part 107, so that the airflow entering the partition 106 is located below the sealing part 107. This forms a structure where the airflow cools the outer wall surface of the inner pot 2 located below the sealing part 107. When the main air duct 103 is connected to the first air duct 104, the airflow enters the partition 106 through the first air duct 104. Because the airflow is blocked by the vertical structure of the sealing part 107, the airflow is confined within the sealing part 107. In the space below, airflow is concentrated on the outer wall surface of the inner pot 2 located below the partition 107 to cool the inner pot 2. The inner wall surface of the inner pot 2, corresponding to the outer wall surface below the partition 107, is the area where rice is placed. In this area, the rice is in contact with the inner wall surface of the inner pot 2. Through concentrated cooling by airflow, a water film can be formed between the rice and the inner wall surface of the inner pot 2 to prevent the rice from sticking to the inner wall surface of the inner pot 2, thus achieving a better non-stick effect for the rice.

[0051] In this design, to further enhance the effect of concentrated airflow cooling of the inner pot 2, thereby improving the non-stickiness of the rice, water level markers A and B are provided on the inner wall surface of the inner pot 2 to indicate the water level. Water level marker A is positioned above water level marker B. Water level marker A can be the mark for the highest water level, and water level marker B can be the mark for the lowest water level. Users can add rice or water according to water level markers A and B. Water level markers A and B also indirectly limit the amount of rice that can be cooked in the inner pot 2. To achieve concentrated airflow cooling of the rice-containing area in the inner pot 2, water level marker A is positioned above the center of the vertical height of the inner pot 2 and below two-thirds of the vertical height of the inner pot 2. A partition 107 is also provided... The vertical height position is below the water level indicator A and above the water level indicator B. This allows the airflow to enter the partition 106 and concentrate on cooling the inner pot 2 within the space below the sealing part 107. The airflow does not pass upward through the sealing part 107, but is concentrated below the sealing part 107, that is, on the outer wall surface of the inner pot 2 corresponding to the area where rice is placed inside the inner pot 2. Instead of cooling the entire outer wall surface of the inner pot 2, the airflow is limited to the spatial area of ​​the airflow. This allows for more concentrated cooling and prevents the airflow from dispersing. The airflow also provides a better non-stick effect for the rice in the area where the inner pot 2 is being cooled. A water film forms between the rice and the inner wall surface of the inner pot 2 to prevent the rice from sticking to the inner wall surface, thus achieving a better non-stick effect.

[0052] When the airflow enters the partition 106, it is concentrated in the space formed by the partition 107, the inner wall surface of the pot cavity 101, and the outer wall surface of the inner pot 2 located below the partition 107. This allows for concentrated cooling of the outer wall surface corresponding to the area containing rice in the inner pot 2, reducing airflow dispersion and loss, and achieving a better cooling effect. This enables rapid cooling of the inner pot 2, resulting in better non-stick properties for the rice.

[0053] It is understandable that the outer wall surface of the area above the partition 107 on the inner wall surface of the inner pot 2 does not contain rice. If airflow is used to cool this area, the airflow will be more easily dispersed and there will be a waste of airflow. Since this area does not contain rice, there is no need to cool it to achieve a non-stick effect. Therefore, concentrating the airflow below the partition 107 to cool the outer wall surface of the area below the partition 107 on the inner pot 2 can achieve a better cooling effect, thereby achieving a better non-stick effect for the rice.

[0054] In this scheme, when the heating element 5 is configured to heat the inner pot 2, the switching element 301 is positioned in the second position. That is, when the control board assembly 4 controls the heating element 5 to start heating to heat the inner pot 2, the rice and water in the inner pot 2 are being cooked. The control board assembly 4 controls the switching element 301 to switch to the second position, so that the main air duct 103 is not connected to the first air duct 104, and the main air duct 103 is connected to the second air duct 105. At this time, the airflow can cool the radiator 401, thereby cooling the IGBT, without cooling the inner pot 2. This ensures that the airflow is not dispersed and does not reduce the heating efficiency of the heating element 5 on the inner pot 2. During the heating process of the inner pot 2, the heat of the inner pot 2 will not be carried away by the airflow, but will instead cool the radiator 401, thereby improving the working stability and reliability of the control board assembly 4.

[0055] In this design, when the heating element 5 is configured to not heat the inner pot 2, the switching element 301 is positioned in the first position. This means that when the control board assembly 4 controls the heating element 5 to stop heating, the inner pot 2 is not heated. At this time, the rice in the inner pot 2 can be considered cooked. The control board assembly 4 controls the switching element 301 to switch to the first position, so that the main air duct 103 is connected to the first air duct 104, and the main air duct 103 is not connected to the second air duct 105. At this time, the airflow can cool the inner pot 2, thereby forming a water film between the rice in the inner pot 2 and the inner wall surface of the inner pot 2, making it less likely for the rice to stick to the inner wall surface of the inner pot 2. At the same time, because the main air duct 103 and the second air duct 105 are not connected, the airflow will not disperse, so that the airflow is concentrated into the first air duct 104 and the partition 106 to concentrate on cooling the inner pot 2, achieving a better non-stick effect for the rice.

[0056] The control board assembly 4 in this solution is mainly a circuit board assembly, which includes circuit boards, components and heat sink 401, etc. The control board assembly 4 realizes the working state of the airflow component 102, heating component 5 and switching component 3, thereby enabling the cooking device to perform cooking tasks, such as cooking rice.

[0057] The heat sink 401 is mainly connected to the IGBT on the control board assembly 4. The heat sink 401 is a heat sink structure made of aluminum. The heat sink 401 is used to dissipate heat from the IGBT. The control board assembly 4 mainly uses the IGBT to drive the heating element 5 to heat the inner pot 2.

[0058] In this scheme, the control board assembly 4 is electrically connected to the heating element 5, the airflow element 102, and the switching assembly 3. The control board assembly 4 controls the working state of the heating element 5, such as controlling the heating element 5 to start heating, be in the heating working state, and stop heating. The control board assembly 4 also controls the working state of the airflow element 102, such as controlling the airflow element 102 to work to provide airflow and the airflow element 102 to stop working. The control board assembly 4 also controls the working state of the switching assembly 3, such as controlling the working state of the motor set on the switching assembly 3, controlling the motor to rotate forward or reverse to drive the switching element 301 to rotate and swing, thereby controlling the switching element 301 to switch the current position between the first position and the second position, thereby changing the flow path direction of the airflow through the switching element 301. Among them, the control board assembly 4 is at least used to make the switching assembly 3 work when the heating element 5 stops working, so as to rotate the switching element 301 to the first position and make the airflow element 102 work to generate airflow to cool the inner pot 2. That is, when the control board assembly 4 controls the heating element 5 to stop working, it controls the switching assembly 3 to work. The operation causes the switching component 301 to rotate and swing to switch the current position to the first position, and controls the airflow component 102 to be in working state to provide airflow. At this time, the airflow passes through the main air duct 103 and the first air duct 104 in sequence to enter the partition 106 to cool the inner pot 2, so that the rice in the inner pot 2 has a better non-stick effect; wherein, or, the control board assembly 4 is at least used to cause the switching component 3 to rotate the switching component 301 to the second position and cause the airflow component 102 to work when the heating component 5 is working. Airflow is generated to cool the radiator 401. Specifically, when the control board assembly 4 controls the heating element 5 to work and heat the inner pot 2, the switching assembly 3 is controlled to work so that the switching element 301 rotates and swings to switch the current position to the second position. The airflow element 102 is also controlled to work to provide airflow. At this time, the airflow passes through the main air duct 103 and the second air duct 105 in sequence to cool the radiator 401, thereby cooling the IGBT and improving the stability and reliability of the control board assembly 4.

[0059] In this scheme, when the heating element 5 is working, the control board assembly 4 controls the heating element 5 to start working, and cooks the rice in the pot 2. During the cooking process, the rice is not easy to stick to the inner wall surface of the pot 2. Therefore, the airflow component 102 does not need to cool the pot 2. On the contrary, if the pot 2 is cooled at this time, it will reduce the heating efficiency of the heating element 5, resulting in heat loss and poor cooking effect. At the same time, the control board assembly 4 drives the heating element 5 to reach the rated heating power to control the heating, which causes the IGBT to heat up rapidly. At this time, controlling the airflow component 102 to cool only the radiator 401 can quickly and effectively reduce the IGBT problem and achieve effective cooling through the radiator 401. It can be seen that the structural setting of the switching component 3 enables the airflow component 102 to independently cool only the radiator 401, achieving a better cooling effect and solving the problem of poor cooling effect of radiator 401 caused by airflow dispersion.

[0060] In this design, when the heating element 5 is not operating, the rice cooking process is complete. In this case, the rice is kept warm inside the inner pot 2 or left to stand for a period of time using the residual heat of the inner pot 2. During this process, the rice tends to stick to the inner wall surface of the inner pot 2. Therefore, the airflow element 102 cools the inner pot 2, allowing a water film to form on the inner wall surface of the inner pot 2, reducing the stickiness and achieving a non-stick effect. In this situation, the airflow element 102 continuously provides airflow to cool the inner pot 2, thus ensuring the rice inside the inner pot 2 has a more even temperature. A good non-stick effect is achieved because, understandably, during this process, the control board assembly 4 only controls the airflow component 102 to work without controlling the heating component 5. Therefore, the IGBT on the control board assembly 4 will not generate a lot of heat. At this time, the airflow component 102 does not cool the heat sink 401, which will not affect the working stability of the IGBT. Thus, the airflow component 102 can independently cool the inner pot 2, achieving a better cooling effect. This can solve the problem of poor cooling effect on the inner pot 2 caused by airflow dispersion, and ultimately achieve a better non-stick effect for the rice in the inner pot 2.

[0061] Understandably, without the switching component 3 in this solution, the airflow component 102 would not be able to cool the radiator 401 and the inner pot 2 simultaneously. This would result in relatively dispersed airflow, poor cooling effect on the radiator 401 and the inner pot 2, and reduced heating efficiency of the heating component 5 on the inner pot 2. This is because during the cooking stage of the rice in the inner pot 2, the rice and water mix extensively without sticking, so there is no need to cool the inner pot 2. Furthermore, the dispersed airflow would also lead to poor cooling effect on the radiator 401, potentially causing the IGBT to overheat, which would reduce the stability of the IGBT operation.

[0062] The heating element 5 in this design is mainly set as an electromagnetic coil disk to achieve electromagnetic induction heating of the inner pot 2. This forms a structure in which the heating element 5 does not directly contact the outer wall surface of the inner pot 2 for heating. This can solve the problem of poor cooling effect of the airflow component 102 on the inner pot 2 caused by the heating element 5 being a heating plate structure.

[0063] The cooking device in this solution can be a rice cooker, an electric pressure cooker, or a similar steamer or simmering pot. As long as the structure of this solution is adopted accordingly, the beneficial technical effects of this solution can be achieved.

[0064] For any aspects not covered in this solution, existing technologies can be used or referenced.

[0065] Working Principle: The cooking device of this solution includes a control panel assembly 4, an airflow component 102, and a switching assembly 3. The switching component 301 can be switched between a first position and a second position by controlling the operation of the switching assembly 3, thereby changing the airflow path. When the switching component 301 is in the first position, the airflow component 102 is controlled to direct the airflow towards the inner pot 2, achieving a cooling effect on the inner pot 2. When the switching component 301 is in the second position, the airflow component 102 is controlled to direct the airflow towards the radiator 401, achieving a cooling effect on the inner pot 2. The cooling effect of the heater 401, with only a single airflow component 102, can not only cool the inner pot 2 but also the radiator 401. Furthermore, during the cooling process, full airflow is used for cooling, eliminating airflow dispersion and resulting in better cooling performance for both the inner pot 2 and the radiator 401. It is also more cost-effective, as it eliminates the need for multiple airflow components 102. The switching component 3 can change the airflow path, thereby reducing airflow dispersion and improving the cooling effect on the inner pot 2 and the radiator 401.

In practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present utility model, and all such changes are within the protection scope of the present utility model.
