Description

Technical Field

[0001] This application relates to the technical field of kitchen appliances, and more specifically, to a safe cooking appliance with automatic water inlet and outlet. Background Technology

[0002] An automatic drainage cooking appliance is available, comprising a pot body and an inner pot within the pot body. A drain valve assembly is installed at the bottom of the inner pot, and a drive device within the pot body actuates the drain valve assembly to open when the drain outlet needs to be opened. The pot body also houses a power board. Therefore, within the limited space inside the pot body, the power board, drain valve assembly, drive device, and other electronic components need to be arranged. This presents a problem of limited internal space. During operation, the surface temperature of the heating element can reach 120-180℃. The heat generated by the numerous electronic components can accumulate, causing localized high temperatures that can affect the normal operation of various critical components. For example, the power board may age prematurely due to high temperatures (e.g., capacitor bulging, resistor burnout), leading to power failure or safety accidents. Furthermore, the insulation layer of the drive motor may be damaged by heat, causing motor stalling or short circuits, thus preventing the drain valve assembly from opening properly.

[0003] Typically, a fan assembly for heat dissipation is also installed inside the pot. However, due to the large number of components inside, multiple cooling fans may be required to ensure heat dissipation. In particular, multiple fan assemblies may be needed to dissipate heat from important components such as the drive unit and power board, which further limits cost and space. Utility Model Content

[0004] The purpose of this application is to provide a safe automatic water inlet and outlet cooking appliance. This is achieved by distributing the drive assembly and power board in the same or adjacent quadrants of a two-dimensional orthogonal coordinate system established with the drain valve assembly as the center and the pot body in the front-back and left-right directions. The cooling fan is located in the same or adjacent quadrant as the drive assembly or power board, and both the drive assembly and power board are positioned along the cooling fan's heat dissipation path. This improves the problem that when the power board and drive assembly work together in the limited space inside the pot, heat accumulation can cause the cooking appliance's drainage or even cooking functions to malfunction, and the use of multiple cooling fans further limits cost and space. In addition, the background art and embodiments described herein also present some technical solutions that belong to the subject matter of this invention but can independently solve other technical problems.

A drive assembly is provided on the pot body corresponding to the drain valve assembly. The power supply connection part is electrically connected to the power board.

[0011] In a preferred embodiment, the control board is integrated onto the power board.

[0012] In a preferred embodiment, the power board is vertically installed inside the pot, at least partially located on the outer periphery of the inner pot, and the power board and at least partially located in the same quadrant as the water tank.

[0013] In a preferred embodiment, the pot body is further provided with a temperature measuring component, which is attached to the outer bottom wall of the inner pot and located on the outer periphery of the drain valve component.

[0014] In a preferred embodiment, the pot body has a downwardly extending receiving channel corresponding to the drain valve assembly, the drain valve assembly is located within the receiving channel, the driving assembly includes an adsorption member, the driving assembly controls the movement of the valve body of the drain valve assembly through the adsorption member, the adsorption member is located on the outer periphery of the receiving channel, the pot body also includes a base, the base has an upwardly extending docking channel, the docking channel corresponds to the receiving channel, and the docking portion of the docking channel and the receiving channel is provided with a sealing structure.

[0015] In a preferred embodiment, the pot body further includes an outer shell, a bottom plate, and an inner shell, which are fastened together to form a receiving cavity. The upper surface of the inner shell is used to receive the inner pot. The pot body is also provided with a fan, which is installed on the lower surface of the inner shell to cool the inner shell during cooking.

[0016] The advantages of this application compared to the prior art are:

[0017] This application addresses the problem of malfunction in existing cooking appliances with drainage functions, caused by localized high temperatures due to heat accumulation from the power board and drive components during heating, coupled with the low cooling efficiency of the cooling fans. This application distributes the drive components and power board, at least partially, in different quadrants of a two-dimensional orthogonal coordinate system centered on the drain valve assembly and extending along the front-back and left-right directions of the pot. Specifically, when viewing the cooking appliance from below, with the rear of the pot as the positive X-axis and the top of the X-axis as the positive Y-axis, the drive components and power board are located in the same or adjacent quadrants, as are the cooling fans. Both the drive components and power board are positioned along the cooling fan's heat dissipation path, thus quickly removing the heat generated by the drive components and power board, reducing their temperature rise, and ensuring the normal operation of these two crucial components of the automatically draining cooking appliance during operation, along with the heating device. This guarantees the appliance's performance and eliminates the need for multiple cooling fans, reducing manufacturing costs and optimizing the internal space layout of the pot.

[0029] Existing cooking appliances with drainage functions typically have a drain valve assembly at the bottom of the inner pot. To open this valve, a drive mechanism needs to be installed inside the appliance. However, in pursuit of compact design and overall miniaturization, a common practice is to install the power board (which controls the appliance's power supply) and the drive mechanism within the limited space of the pot. The power board contains transformers, switches, and other components that generate significant heat during operation. The drive mechanism also generates heat, in addition to the heat generated by the heating element during cooking. This accumulation of heat and the resulting localized high temperatures can pose safety risks. Therefore, a more suitable layout for the power board and drive mechanism is urgently needed to ensure the safety and lifespan of the cooking appliance.

[0030] This utility model provides a safe cooking appliance with automatic water inlet and outlet, such as... Figure 1 and Figure 2As shown, the appliance includes a pot body 1, an inner pot 2 housed within the pot body 1, a water tank 3, and a lid 4 covering the pot body 1. The water tank 3 supplies cooking water to the inner pot 2 through a water inlet channel 301. The pot body 1 contains a heating device 5 and a power board 6. A power supply connection part 9 is located at the rear of the pot body 1, electrically connected to the power board 6. After plugging in, the power supply connection part 9 connects to the mains power supply to the power board 6. This power supply connection part 9 can be a power cord or a power cord interface; there are no restrictions here. Existing cooking appliances that require plugging in typically place the power supply connection part 9 at the rear of the appliance, which meets national standards and also serves a certain aesthetic purpose, rationalizing the overall layout of the cooking appliance. The bottom wall of the inner pot 1 has a drain valve assembly 7, and the pot body 1 has a drive assembly 8 corresponding to the drain valve assembly 7. The power board 6 supplies power to the drive assembly 8 and the heating device 5, enabling the power board 6 to rationally distribute voltage after plugging in, ensuring the normal operation of the drive assembly 8 and the heating device 5, thus realizing a cooking appliance with automatic water inlet and outlet. The rear of the cooking appliance can be clearly identified using the power connection part 9, thereby determining the front-back and left-right directions of the cooking appliance. This directional description is easily understood by those skilled in the art and will not be elaborated further here. A two-dimensional orthogonal coordinate system is established with the drain valve assembly 7 as the center, along the front-back and left-right directions of the pot body 1. Specifically, as follows... Figure 2 middle, Figure 2This is a schematic diagram of the internal structure of the pot body 1 viewed from below. When observing the cooking appliance from below, the rear of the pot body 1 is taken as the positive direction of the X-axis, and the top of the X-axis is taken as the positive direction of the Y-axis. The drive component 8 and the power board 6 are located in the same quadrant or adjacent quadrants. The cooling fan 10 is located in the same quadrant or adjacent quadrant as the drive component 8 or the power board 6. Both the drive component 8 and the power board 6 are located on the heat dissipation path of the cooling fan 10. In this way, the drive component 8 and the power board 6 are kept close to each other, and the cooling fan used to blow out the heat dissipation airflow can also be close to the drive component 8 and the power board 6. They are in the heat dissipation path of the cooling fan 10, which can quickly remove the heat generated by the drive component 8 and the power board 6, reduce the temperature rise of the two, and ensure that the two important components of the cooking appliance that can automatically fill and drain water can work normally during the operation of the cooking appliance, along with the operation of the heating device 5. This ensures the performance of the cooking appliance, and eliminates the need for multiple fan components, reducing manufacturing costs and optimizing the internal space layout of the pot body 1. It also improves the heat dissipation efficiency of the cooling fan 10, and further ensures that the drain valve component 7 can be driven to open by the drive component 8. The above arrangement can also make the internal space of the pot body 1 compact, realizing the miniaturization design of the cooking appliance. It is understood that the heat dissipation path of the cooling fan 10 in this application includes the area directly or indirectly cooled during the process of the cold air blown out by the cooling fan 10 flowing inside the pot body 1 and being discharged from the pot body 1, or the area directly or indirectly cooled during the process of the cold air drawn into the pot body 1 by the cooling fan 10 and being discharged from the air outlet of the cooling fan 10. In other words, the area that the airflow path drawn in or blown out by the cooling fan 10 can pass through is the heat dissipation path, while components or parts that are blocked inside the pot body 1 cannot be located in the heat dissipation path of the cooling fan 10. The position directly facing the air outlet of the cooling fan 10 or that can be directly blown by the airflow it generates is the first heat dissipation path. The first heat dissipation path can come into contact with the cooler air and thus remove more heat.

[0031] In some implementations, see also Figure 2The drive component 8 and the power board 6 are both located in the first and fourth quadrants of a two-dimensional orthogonal coordinate system, that is, they are located in the same quadrant. This brings the drive component 8 and the power board 6 closer together. At this time, the cooling fan 10 is also located in the first and fourth quadrants. With all three located in the same quadrant, the difficulty of the airflow generated by the cooling fan 10 reaching the drive component 8 and the power board 6 is greatly reduced, optimizing the heat dissipation path and making the spatial arrangement more compact. This is beneficial to the proper operation of the drive component 8 and the power board 6. At the same time, the layout of the cooling fan 10, the drive component 8 and the power board 6 in this application can increase the heat dissipation efficiency of the cooling fan 10, reduce the ineffective flow of heat dissipation airflow, effectively reduce the required heat dissipation power, protect the heat dissipation components and extend the service life of the cooking appliance. It is known that the cooling fan 10, the drive component 8, and the power board 6 all have certain dimensions. In the two-dimensional orthogonal coordinate system established in this application, the cooling fan 10, the drive component 8, and the power board 6 can be located entirely in one of the four quadrants, or they can be located in several of the four quadrants, depending on actual needs. In this application, it is only necessary to ensure that the drive component 8 and the power board 6 are either located in the same quadrant or in adjacent quadrants. For example, when the drive component 8 is located in the first quadrant, and the power board 6 is located in both the first and fourth quadrants, the power board 6 is either in the same quadrant as the drive component 8 or in an adjacent quadrant. The cooling fan 10 only needs to satisfy the relationship of being in the same quadrant or an adjacent quadrant with either the drive component 8 or the power board 6. This achieves the arrangement scheme defined in this application. Similarly, when the cooling fan 10 is entirely located in the first quadrant, both the power board 6 and the drive component 8 are located in the fourth quadrant. In fact, the power board 6 and the drive component 8 are in the same quadrant, and the cooling fan 10 is in an adjacent quadrant with both the power board 6 and the drive component 8. This also achieves the arrangement scheme defined in this application. All schemes that satisfy the arrangement scheme defined in this application will not be exhaustively listed hereafter. Those skilled in the art can understand how to arrange the cooling fan 10, the drive component 8, and the power board 6 to achieve the scheme of this application after reading this application specification. Thus, by realizing the arrangement scheme of the three components in the internal space of the pot body 1 as defined in this application, the efficiency of the cooling fan 10 for the two important components can be improved, overheating can be prevented from affecting the operation of both components, the operation of the drainage and cooking functions can be ensured, and the occurrence of safety accidents such as component burnout can be reduced.

[0032] In some implementations, such as Figure 2As shown, the circumferential contour projection of the pot body 1 in the height direction is a quadrilateral. Whether it is a right-angled quadrilateral or a rounded quadrilateral, it belongs to the quadrilateral described in this application. According to the front-back direction and the left-right direction of the pot body 1, it is divided into front side, rear side, left side and right side. In the two-dimensional orthogonal coordinate system established above, the front side is located in the second quadrant and the third quadrant, the rear side is located in the first quadrant and the fourth quadrant, the left side is located in the third quadrant and the fourth quadrant, and the right side is located in the first quadrant and the second quadrant. In this example, the drive component 8, the power board 6 and the cooling fan 10 are all located on the rear side. First of all, the cooling fan 10 can send more unheated airflow (the airflow temperature is lower than the surface temperature of each component) to the drive component 8 and the power board 6, improve the cooling efficiency of the cooling fan 10 for the two, and prevent the two important components from overheating. Since users usually operate the cooking appliance from the front side, placing them all on the rear side can improve the user's bad experience caused by the heat of the cooking appliance. Overall, it makes the cooking appliance work more safely and stably and provides a good user experience. In other examples, the drive assembly 8 is located in the front second quadrant, and the power board 6 is located in the front third quadrant, both in adjacent quadrants. The cooling fan 10 is located in the second and third quadrants, or simultaneously in both quadrants. This allows the cooling fan 10 to effectively cool the drive assembly 8 and the power board 6, and makes the components within the pot body 1 more compact, contributing to the miniaturization of the cooking appliance. It is understood that, besides the aforementioned arrangement of the cooling fan 10, drive assembly 8, and power board 6 according to the orientation of the circumferential contour of the pot body 1, other arrangements are possible, as long as the drive assembly 8 and power board 6 are located in the same or adjacent quadrants, and the cooling fan 10 is located in the same or adjacent quadrant as one of them. Similarly, when the circumferential contour projection of the outer contour of the pot body 1 in the height direction is circular or other shapes, it also has a front, rear, left, and right side, but regular shapes, such as quadrilaterals or circles, facilitate the arrangement of various components and result in a smoother and more aesthetically pleasing appearance.

[0033] In some embodiments, the power board 6 is located on the first heat dissipation path of the cooling fan 10. To ensure that the temperature rise of the power board 6, which generates the most heat besides the heating device 5, is within a safe range during the operation of the cooking appliance, the airflow generated by the cooling fan 10 flows inside the pot body 1. Since the power board 6 is located on the first heat dissipation path of the cooling fan 10, the airflow flows out to the outside after flowing inside the pot body 1, effectively removing some of the heat from the external environment and ensuring the safe use of the cooking appliance. Placing the power board 6 on the first heat dissipation path of the cooling fan 10 is beneficial because the power board 6 carries high voltage and has many electronic components, generating a large amount of heat during operation. If this heat is not dealt with promptly, it may burn out the power board 6, causing a safety accident. To avoid this, the first heat dissipation path ensures that the airflow generated by the cooling fan 10 contacts the power board 6 faster than other components, maximizing the heat dissipation of the power board 6. The first heat dissipation path of the cooling fan 10 is defined as the area directly opposite the airflow direction of the cooling fan 10, that is, the path from when the airflow is blown out by the cooling fan 10 until it encounters an obstacle or the cavity wall of the pot body 1 and changes direction. This first heat dissipation path has high heat dissipation efficiency and ensures safety. In some examples, the cooling fan 10 blows directly onto the power board 6, which has a better heat dissipation effect on the power board 6. In other examples, the drive component 8 is also located on the first heat dissipation path of the cooling fan 10. Specifically, the exhaust port of the cooling fan 10 can be set so that both the drive component 8 and the power board 6 are located on the first heat dissipation path. When the power board 6 and the drive component 8 are large or their positions are not compact, the cooling fan 10 can be tilted or the exhaust port area can be increased to place both the drive component 8 and the power board 6 on the first heat dissipation path. In this way, the heat dissipation of the two components can be maximized, thereby ensuring the normal operation of both.

[0034] In some implementations, such as Figure 1As shown, the power board 6 is vertically installed inside the pot body 1, with at least a portion of it located on the outer periphery of the inner pot 2. Since the power board 6 is a plate-shaped circuit board structure, if it were laid flat inside the pot body 1, the pot body 1 would need to support the inner pot 2, increasing the lateral dimension of the cooking appliance. This would result in an excessively large appliance, making it difficult to move and inconvenient for users, and would also increase manufacturing costs. Alternatively, placing the power board 6 flat under the inner pot 2, while reducing the increase in lateral dimension by accommodating it vertically, requires adding water to the inner pot 2 or at least partially draining the liquid from it, as the cooking appliance of this application involves automatic water inlet and outlet. This can lead to moisture accumulation or increased humidity above or below the inner pot 2, making the power board 6 more susceptible to damage and potentially affecting the normal operation of the cooking appliance or causing safety accidents. Therefore, this application installs the power board 6 vertically, with at least a portion of it positioned on the outer periphery of the inner pot 2. This reduces the horizontal space occupied by the power board 6 and avoids excessively increasing the vertical dimensions of the cooking appliance, allowing for a more compact arrangement of components within the pot body 1. Furthermore, it reduces the negative impact of the upper-inlet and lower-outlet water-drainage structure of the inner pot 2 on the power board 6, making the cooking appliance safer to use. It should be noted that vertical installation refers to the overall plate-like structure of the power board 6 being placed with an overall tendency towards verticality. This can be either vertically or nearly vertically positioned, as long as the projected area of ​​the power board 6 facing the horizontal direction is greater than its projected area facing the vertical direction; no specific restrictions are imposed here.

[0035] In some embodiments, in the aforementioned established two-dimensional orthogonal coordinate system, the power board 6 and at least part of the water tank 3 are located in the same quadrant, thereby bringing the power board 6 and the water tank 3 closer together. Since the water tank 3 contains water or other liquids to be added to the inner pot 2 during cooking, the liquid in the water tank 3 can absorb a large amount of heat generated by the power board 6 during operation. Furthermore, once the power board 6 starts working, it is known that the cooking appliance is also working. The heat absorbed by the liquid in the water tank 3 can raise the liquid to a certain temperature. Adding this heated liquid to the inner pot 2 can, to some extent, improve the cooking efficiency of the appliance. This arrangement not only reduces the temperature rise of the power board 6 and improves the safety factor, but also increases the temperature of the liquid added to the inner pot 2 through the water filling channel 301, resulting in higher cooking efficiency. If combined with a vertically installed power board 6, by increasing the convection area, the water tank 3 can remove even more heat from the power board 6.

[0036] In some embodiments, a control board 11 is also included. The control board 11 is electrically connected to the drive assembly 8 and the power board 6, respectively. The control board 11 contains a main control unit such as an MCU for executing the cooking program. The power board 6 supplies power to the control board 11. The control board 11 controls the drive assembly 8 to work when needed according to the cooking program, thereby driving the drain valve assembly 7 to open. In addition, the control board 11 and the drive assembly 8 can be located at least partially in the same quadrant, and / or the control board 11 and the power board 6 can be located at least partially in the same quadrant, thereby facilitating electrical connection. The following example illustrates this:

[0037] In some examples, the control board 11 is located in the second and third quadrants, as are the drive assembly 8 and the power board 6, ensuring they are all in the same quadrant. This facilitates wiring connections between the control board 11, drive assembly 8, and power board 6, simplifying the wiring layout within the pot body 1, reducing tangling, and simplifying assembly, thus lowering manufacturing costs. Furthermore, since all three are in the same quadrant, preferably, the drive element 801 of the drive assembly 8 is also located in the second or third quadrant, bringing it closer to the control board 11 for easier electrical connection. The cooling fan 10 is located in at least the same or adjacent quadrant as either the power board 6 or the drive assembly 8, allowing for faster or more direct cooling of the control board 11, power board 6, and drive assembly 8, resulting in high cooling efficiency. In other examples, the control board 11 and power board 6 may also be at least partially located in the same quadrant, as the power board 6 also needs to be electrically connected to the control board 11, thus requiring wiring as well. Preferably, when the control board 11, the power board 6, and the drive assembly 8 all have portions located in the same quadrant, the portions of the three in the same quadrant can be used to facilitate their wiring relationship, thereby making the wiring simpler and further rationalizing the internal spatial layout of the pot body 1.

[0038] In some embodiments, a display panel 12 is also included. The display panel 12 is located on the pot body 1 at the interactive interface of the cooking appliance. The user can input commands to the display panel 12 through the interactive interface. The display panel 12 then inputs the commands to the control board 11, and the control board 11 responds to the commands by performing corresponding actions on the drive assembly 8 and the heating device 5. Furthermore, the control board 11 is integrated into the display panel 12, specifically located on the side of the display panel 12 closer to the inner pot 2. This further integration can greatly simplify the connection wiring harness.

[0039] In some embodiments, the heating device 5 is an electromagnetic coil, and the main control board controlling the electromagnetic coil is integrated on the power board 6. The IGBT that drives the electromagnetic coil is located on this main control board. In this way, the electronic components that generate the most heat in the cooking appliance, such as the IGBT, rectifier bridge, and switching power supply, can be concentrated on the power board 6. Through the thermal conductivity of the metal plate, combined with the cooling fan 10, heat dissipation can be concentrated on these electronic components, resulting in high thermal management efficiency. Furthermore, separating the strongest interference sources (IGBT, power board 6, etc.) from the most sensitive control board 11, and transmitting filtered signals through wires, greatly reduces the risk of interference, ensuring the stability of the entire circuit system. This modular design also makes fault location easy. If there are display problems or control malfunctions, only the control board 11 on the display board 12 or the MCU on the control board 11 needs to be replaced, making maintenance easy. The heating device 5 is located below the inner pot 2. Since the electromagnetic coil needs to be wound, the drive assembly 8 is located below the heating device 5. This way, the electromagnetic coil does not need to avoid the drive assembly 8 during winding, and the drive assembly 8 also has sufficient space to drive the drain valve assembly 7 on the bottom wall of the inner pot 2. Furthermore, to reduce the influence of the electromagnetic coil on the drive assembly 8, a magnetic strip is provided between the drive assembly 8 and the heating device 5. The magnetic strip can effectively isolate the magnetic field generated by the electromagnetic coil from the potential influence on the drive assembly 8, thereby ensuring the proper operation of the drive assembly 8.

[0040] In some embodiments, the drain valve assembly 7 protrudes downwards from the center of the bottom of the inner pot 2. This allows the liquid in the inner pot 2 to flow evenly out of the external environment through the drain valve assembly 7. This arrangement also reduces the impact of the protruding drain valve assembly 7 on the shape of the heating device 5. When using an electromagnetic coil, the common structure of the electromagnetic coil is that it is wound on a winding post. In this case, the drain valve assembly 7 located at the center of the bottom of the inner pot 2 or the corresponding channel on the pot body 1 can act as a winding post or a fixing post. The coil support or electromagnetic coil of the electromagnetic coil can be wound on the aforementioned channel, ensuring the integrity of the heating device 5 itself. To the greatest extent possible, while retaining the original structure of the cooking appliance, only the drain valve assembly 7 at the bottom of the inner pot 2 and the drive assembly 8 in the pot body 1 need to be added to achieve the drainage function. This does not have a negative impact on the cooking performance and can even enhance the cooking function. The pot body 1 is also provided with a temperature measuring component 13. The temperature measuring component 13 is attached to the outer bottom of the inner pot 2 and located on the outer periphery of the drain valve assembly 7. The real-time temperature of the bottom of the inner pot 2 is measured by the temperature measuring component 13. The temperature measuring component 13 is electrically connected to the control board 11 and transmits the real-time temperature signal to the control board 11. The control board 11 controls the cooking program according to the signal. Alternatively, when the real-time temperature signal exceeds the limited temperature threshold, the fuse of the temperature measuring component 13 will melt, thereby controlling the heating device 5 to stop heating.

[0041] In some implementations, such as Figure 3 As shown in the exploded perspective view of the cooking appliance, the pot body 1 also includes an outer shell 101, a bottom plate 102, and an inner shell 103. These three parts are fastened together to form a cavity for accommodating components such as the drive assembly 8 and the power board 6. The inner shell 103 is a concave shell with an upward opening, and its upper surface is used to accommodate the inner pot 2. The heating device 5 is installed on the lower surface of the inner shell 103. When heating is performed using an electromagnetic coil, the alternating magnetic field generated by the electromagnetic coil acts on the inner pot 2, which has a magnetic conductive layer, but has no effect on the inner shell 103. The inner shell 103 effectively protects the electromagnetic coil. The power board 6 is mounted on the power board bracket 601, which better secures it inside the pot body 1. The power board bracket 601 is also vertically mounted, allowing for a more compact interior and more reasonable spacing between components. The power board bracket 601 has a mounting slot for the cooling fan 10 at its bottom, ensuring the power board 6 is positioned along the first heat dissipation path of the cooling fan 10. By defining the position of the cooling fan 10 and ensuring its stable installation, at least a portion of the airflow from the cooling fan 10 is directed towards the power board 6 along the first heat dissipation path, improving heat dissipation efficiency. The water tank 3 is mounted on the rear side of the outer casing 101, making the overall structure more compact in the left-right direction of the cooking appliance. The drain valve assembly 7 at the bottom of the inner pot 2 protrudes outward from the outer bottom of the inner pot 2, while the inner shell 103 has a receiving channel 1031 for accommodating the drain valve assembly 7. The receiving channel 1031 ensures that after the inner pot 2 is placed in, the drain valve assembly 7 is at least partially located within the receiving channel 1031, preventing the presence of the drain valve assembly 7 from causing an excessive distance between the inner pot 2 and the heating device 5, thus ensuring the heating efficiency of the heating device 5 on the inner pot 2. The pot body 1 also contains a fan-cooled fan 14, which can be installed on the lower surface of the inner shell 103. The fan-cooled fan 14 can blow air to cool the inner shell 103 during certain stages of the cooking process, reducing the temperature of certain parts of the inner pot 2 at certain stages. Water vapor will condense on the inner surface of the inner pot 2, forming a certain degree of water film. The formation of this water film can prevent the food in the inner pot 2 from sticking to its inner surface and causing it to stick to the pot.

[0042] In some embodiments, the pot body 1 has a downwardly extending receiving channel 1031 corresponding to the drain valve assembly 7. The drain valve assembly 7 is located in the receiving channel 1031. The drive assembly 8 controls the movement of the valve body 701 of the drain valve assembly 7 by magnetic force. The pot body 1 also includes a base with an upwardly extending docking channel (not shown in the figure). The docking channel corresponds to the receiving channel 1031. The docking part of the docking channel and the receiving channel 1031 is provided with a sealing structure (not shown in the figure). The docking channel can extend into the receiving channel 1031, or the receiving channel 1031 can extend into the docking channel, or there can be a certain gap between the docking ends of the docking channel and the receiving channel 1031. This gap is sealed and isolated by a sealing structure. After the sealing structure seals or blocks the docking part of the two, the liquid falling from the drain valve assembly 7 or the steam flowing in the channel cannot come into contact with the components or parts outside the receiving channel 1031, which plays a protective role for the electronic components inside the cooking appliance, and can reduce the humidity of the internal environment of the pot body 1, making the components less susceptible to corrosion, especially better protecting the cooling fan 10, the power board 6 and the drive assembly 8, and extending the service life of the cooking appliance.
