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] A cooking appliance with automatic drainage includes a pot body and an inner pot located within the pot body. It utilizes a drain valve assembly at the bottom of the inner pot, and a drive mechanism within the pot body activates the drain valve assembly when needed. Since at least some liquid inside the inner pot is drained through the drain outlet, this drainage may result in either a wastewater box within the appliance or discharge into the external environment. Regardless of the discharge method, the path passes through the interior of the appliance, easily causing the humidity inside to exceed that of the external environment, creating a damp environment. Furthermore, the power board within the appliance carries high voltage, while the drive mechanism typically carries low voltage. Therefore, within the confined space of the pot body and the damp environment, arcing or breakdown can easily occur between the two, damaging electrical components. Additionally, the high voltage from the power board may interfere with the normal operation of the drive mechanism's motor or solenoid valves, significantly impacting the appliance's usability.

[0003] At the same time, both the drive unit and the power board generate a lot of heat. The heat accumulation will form local high temperatures, which will affect the lifespan of each module. Utility Model Content

[0004] The purpose of this application is to provide a safe automatic water inlet and outlet cooking appliance. By distributing the drive assembly 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 body, this improves the problem of poor appliance performance caused by mutual interference between the power board and drive assembly within the limited space inside the pot body. 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.

[0005] The embodiments of this application are implemented as follows:

[0006] This utility model provides a safe automatic water inlet and outlet cooking appliance, including a pot body, an inner pot disposed within the pot body, a water tank, and a lid covering the pot body. The water tank supplies cooking water to the inner pot through a water inlet channel. The pot body is equipped with a heating device and a power board. A power supply connection part is also provided at the rear of the pot body. A drain valve assembly is provided on the bottom wall of the inner pot. 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. A two-dimensional orthogonal coordinate system is established with the drain valve assembly as the center along the front-back direction and the left-right direction of the pot body. The drive assembly and the power board are at least partially located in different quadrants.

[0007] In a preferred embodiment, the drive component and the power board are located in different quadrants of the two-dimensional orthogonal coordinate system.

[0008] In a preferred embodiment, a portion of the drive assembly is located in the same quadrant as a portion of the power board.

[0009] In a preferred embodiment, a cooling fan is also included, and the power board is located on the first heat dissipation path of the cooling fan.

[0010] 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.

[0011] In a preferred embodiment, the system further includes a control board electrically connected to both the drive assembly and the power board, wherein the control board and the drive assembly are at least partially located in the same quadrant, and / or the control board and the power board are at least partially located in the same quadrant.

[0012] In a preferred embodiment, the appliance further includes a display panel located at the interface of the cooking appliance, and the control panel is integrated on the display panel.

[0013] In a preferred embodiment, the heating device is an electromagnetic coil, and the main control board controlling the electromagnetic coil is integrated on the power board.

[0014] In a preferred embodiment, the control board is integrated onto the power board.

[0015] In a preferred embodiment, the drain valve assembly protrudes downwards from the center of the bottom of the inner pot, and the pot body is also 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 assembly.

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

[0017] This application addresses the problem of excessive internal components in existing cooking appliances with drainage functions, where the two crucial parts—the drive assembly and the power board—interfere with each other. This application distributes at least partially the drive assembly and power board in different quadrants of a two-dimensional orthogonal coordinate system established with the drain valve assembly as the center and the pot's front-back and left-right directions. 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 assembly and power board are at least partially located in different quadrants. This ensures that the power board is at least partially farther away from the drive assembly than the drain valve assembly, significantly reducing the power board's influence on the drive assembly and guaranteeing sufficient creepage distance and clearance, thus achieving a safer automatic water inlet and outlet cooking appliance.

[0030] 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 is needed within the appliance. However, to achieve a 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, and the accumulated heat from both can interfere with each other's operation. Furthermore, the power board is directly connected to high-voltage AC 220V, and the high voltage it carries may affect the normal operation of actuators or solenoid valves within the drive mechanism. Therefore, a power board and drive mechanism layout solution that ensures the safety and lifespan of the cooking appliance is urgently needed.

[0031] This utility model provides a safe cooking appliance with automatic water inlet and outlet, such as... Figure 1 and Figure 2 As 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 2 This is a schematic diagram showing the internal structure of the pot body 1 viewed from below. When observing the cooking appliance from this angle, the rear of the pot body 1 is taken as the positive X-axis, and the top of the X-axis is taken as the positive Y-axis. The drive assembly 8 and the power board 6 are at least partially located in different quadrants. This ensures that the power board 6 is at least partially located away from the drive assembly 8 relative to the drain valve assembly 7, thereby significantly reducing the impact of the power board 6 on the drive assembly 8, ensuring sufficient creepage distance and electrical clearance, and achieving a safer automatic water inlet and outlet cooking appliance.

[0032] In some implementations, see also Figure 2 The drive assembly 8 and the power board 6 are located in different quadrants of the two-dimensional orthogonal coordinate system, meaning they are not arranged in the same quadrant. This further distances the drive assembly 8 and the power board 6, reducing interference from high voltage and preventing heat buildup in one area that could cause excessive temperature rise in the drive assembly 8 and power board 6, thus affecting normal operation. The drain valve assembly 7 and its associated parts also isolate the drive assembly 8 and power board 6 to a certain extent, further reducing interference between them. In addition, the layout of the drive assembly 8 and power board 6 in this application reduces the heat dissipation burden on the cooking appliance, effectively lowers the required heat dissipation power, protects the heat dissipation components, and extends the service life of the cooking appliance. It is known that both the drive assembly 8 and the power board 6 have certain dimensions. In the two-dimensional orthogonal coordinate system established in this application, the drive assembly 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. This application only needs to ensure that at least part of the drive assembly 8 and the power board 6 are located in different quadrants to reduce the mutual influence between them and improve the safety factor of the cooking appliance.

[0033] In some implementations, such as Figure 3 As shown, a portion of the drive assembly 8 and a portion of the power board 6 are located in the same quadrant. Thus, while ensuring that the other parts of each can be kept away from each other, placing a portion of each in the same quadrant can not only improve the mutual influence between the drive assembly 8 and the power board 6, but also reduce the excessive space occupied by the two in the pot body 1. To a certain extent, it takes into account both safety considerations and miniaturization design, and the layout is more reasonable.

[0034] In some embodiments, 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, all of which belong to the quadrilaterals described in this application. Based on the front-back direction and left-right direction of the pot body 1, it is divided into front, rear, left, and right sides. In the aforementioned established two-dimensional orthogonal coordinate system, the front side is located in the second and third quadrants, the rear side is located in the first and fourth quadrants, the left side is located in the third and fourth quadrants, and the right side is located in the first and second quadrants. In some examples, such as... Figure 2As shown, the drive assembly 8 is located on the front side, while the power board 6 is located on the rear side. In this arrangement, the drive assembly 8 and the power board 6 are distributed on both sides of the drain valve assembly 7, centered on the drain valve assembly 7. This makes efficient use of the internal space within the pot body 1 and significantly reduces the mutual interference between the drive assembly 8 and the power board 6, resulting in safer, more stable, and quieter operation of the cooking appliance. In other examples, the drive assembly 8 is located on the front side, and the power board 6 is located on the left or right side. The drive assembly 8 and the power board 6 are arranged adjacent to each other with the drain valve assembly 7 as the center, making the components within the pot body 1 more compact and contributing to the miniaturization of the cooking appliance. It is understood that, besides the aforementioned arrangement of the drive assembly 8 and the 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 the power board 6 are at least partially located in different quadrants. Similarly, when the outer contour of the pot body 1 is projected in the circumferential contour in the height direction as a circle or other shape, it also has a front, back, left and right side, but regular shapes, such as quadrilaterals or circles, are more convenient for the arrangement of various components, and the appearance is more smooth and beautiful.

[0035] In some embodiments, a cooling fan 10 is also included, with the power board 6 located on the first heat dissipation path of the cooling fan 10. To ensure that the temperature rise inside the pot 1 remains within a safe range during the operation of the cooking appliance, the cooling fan 10 is added. The airflow generated by the cooling fan 10 flows inside the pot 1 and then outwards, effectively removing some 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 contains many electronic components, generating a large amount of heat during operation. If this heat is not handled promptly, it could burn out the power board 6 and cause 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 heat dissipation for the power board 6. The first heat dissipation path of the cooling fan 10 is defined as the position along the airflow direction of the cooling fan 10, that is, the airflow after it is blown out of the cooling fan 10 until it encounters an obstacle or the cavity wall of the inner cavity of the pot body 1 and changes direction. This first heat dissipation path has high heat dissipation efficiency and ensures safety. Preferably, the cooling fan 10 blows directly onto the power board 6 to maximize the heat dissipation of the power board 6.

[0036] 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.

[0037] 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.

[0038] 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:

[0039] In some examples, such as Figure 2 As shown, the control board 11 is located in the second and third quadrants, the drive assembly 8 is also located in the second and third quadrants, and the power board 6 is located in the first and fourth quadrants. This arrangement ensures that the control board 11 and the drive assembly 8 are in the same quadrants, while the power board 6 is in a completely different quadrant. This facilitates the wiring connection between the control board 11 and the drive assembly 8, simplifying the wiring layout within the pot body 1, reducing the risk of tangling, simplifying assembly, and lowering manufacturing costs. Furthermore, since the drive assembly 8 and the power board 6 are located in completely different quadrants, the heat from the power board 6 can be reduced to minimize its impact on the control board 11, ensuring its normal operation. In other examples, such as... Figure 3 As shown, the control board 11 is located in the second and third quadrants, and the drive assembly 8 is located in the third and fourth quadrants. Both the control board 11 and the drive assembly 8 have portions located in the third quadrant, which facilitates wiring and simplifies the internal wiring layout. Preferably, the drive element 801 of the drive assembly 8 is located in the third quadrant, making the drive element 801 closer to the control board 11 for easier electrical connection. In other examples, the control board 11 and the power board 6 may also be located at least partially in the same quadrant, since 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, while the power board 6 and the drive assembly 8 are located in different quadrants, the portions of the three in the same quadrant can be used to facilitate their connection, thus simplifying the wiring. The purpose of this application is to further optimize the internal spatial layout of the pot body 1 by having other portions of the power board 6 located in different quadrants from the drive assembly 8, thereby reducing the impact of the power board 6 on the drive assembly 8.

[0040] 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.

[0041] 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.

[0042] In some implementations, the control board 11 is integrated on the power board 6, and the main control board of the heating device 5 is also integrated on the power board 6. All of them are integrated on one board, which can eliminate the need for PCB boards and multiple connectors, resulting in the lowest material and assembly costs and a simple structure.

[0043] 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.

[0044] In some implementations, such as Figure 4As 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 blow air onto 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 moisture film. The formation of this moisture film can prevent the food in the inner pot 2 from sticking to its inner surface and causing it to stick to the pot.
