Description

Technical Field

[0001] This utility model belongs to the field of home appliances, and more specifically, it relates to an electric cooking appliance base and an electric cooking appliance. Background Technology

[0002] In the field of electric cooking appliances, heating devices such as electric kettles and health pots typically adopt a split structure design, consisting of a base assembly and a cooking container. Their control modules (including touch components and electronic control units) are usually integrated inside the base to meet reliability requirements such as waterproofing and stain resistance.

[0003] In the prior art, in order to optimize the human-computer interaction experience, the touch operation interface is usually designed as a tilted structure with an angle of 10°-30° relative to the horizontal plane of the base, so that the operation plane faces the user's line of sight in the normal use posture. Although this design can improve the convenience of operation and information visibility, it has the following technical defects: (1) Insufficient structural adaptability: To achieve effective transmission of touch signals, a sensing spring needs to be set between the button and the circuit board. When the operation interface is tilted, in order to ensure the consistency of the axial deformation of the spring, the existing solution requires the touch circuit board to be arranged parallel to the operation interface. This forced angle adaptation results in: the need to design a special irregular touch control circuit board or add an adapter bracket, which significantly increases the manufacturing complexity and cost; the tilted installation method occupies the vertical space inside the base, which limits the flexibility of the layout of other components. (2) High system integration difficulty: When the main control board and the touch board are integrated, the traditional tilted layout method results in the overall circuit module having a wedge-shaped structure. In order to accommodate this irregular structure, the volume of the base shell needs to be increased accordingly, which is contrary to the design trend of miniaturization and compactness of kitchen appliances.

[0004] The aforementioned technical contradictions indicate that existing electric cooking appliances, while pursuing ease of operation, struggle to simultaneously address manufacturing feasibility, space utilization, and long-term reliability. Therefore, developing a base structure that maintains the advantages of human-computer interaction while enabling standardized integration of the circuit system has become a pressing technical challenge in this field. Summary of the Invention

[0005] To address the aforementioned technical problems, this utility model provides an electric kettle, which solves the problem in the prior art where the unreasonable fit between the buttons and the circuit board leads to unstable performance, complex structure, and excessive size of the cooker base.

[0006] To achieve the above objectives, this utility model is accomplished by the following specific technical means:

[0007] An electric cooker base includes: a housing and a touch control circuit board; the housing has a button area, and the housing interior has a receiving cavity for accommodating the touch control circuit board; the touch control circuit board is disposed within the receiving cavity; the button area has a planar or arc-shaped structure; when the button area has a planar structure, an angle α is formed between the button area and the touch control circuit board; when the button area has an arc-shaped structure, an angle α is formed between the tangent of the center point of the button area and the touch control circuit board; α∈(0°, 90°); a cylindrical elastic sensing element is connected between the inner end face of the button area and the touch control circuit board, and a limiting element is provided on the inner end face of the button area; one end of the elastic sensing element is fixedly connected to the touch control circuit board, and the other end is sleeved around the limiting element and abuts against the inner end face of the button area.

[0008] Compared with the prior art, this utility model has the following advantages: the button area is tilted, which ensures the user's observation and operation. Through the synergistic effect of the limiting component and the cylindrical elastic sensing component, the elastic sensing component is radially constrained, allowing it to undergo necessary axial deformation, but effectively controlling its radial offset, preventing the spring from detaching from the inner end face of the button area, and ensuring stable transmission of touch signals. At the same time, there is no need to design a touch control circuit board or add an adapter bracket to adapt to the tilted interface, which simplifies the manufacturing process and reduces costs. The touch control circuit board can be placed horizontally, avoiding the occupation of the internal vertical space of the base by tilted installation.

[0009] Furthermore, the button area has two or more buttons.

[0010] Furthermore, the inner end face of the housing is provided with isolation ribs between the button areas to isolate electrical signals between adjacent sensing elastic elements and prevent accidental touches.

[0011] Furthermore, the line connecting the button area and the sensing spring at the connection position on the touch control circuit board is in the direction X, the extension direction of the limiting member is Y, and the angle β between the direction X and the direction Y, β∈(0°, 90°), effectively restricts its disengagement.

[0012] Furthermore, the end of the limiting member is provided with a smooth portion to prevent wear on the elastic sensing member when the end of the limiting member comes into contact with it.

[0013] Furthermore, the elastic sensing element is a sensing spring.

[0014] Furthermore, it also includes a main control circuit board for the cooker, which is integrated with the touch control circuit board to reduce the complexity of the circuit board structure.

[0015] Furthermore, it also includes a power supply terminal connected to the cooker. The power supply terminal is electrically connected to the main control circuit board of the cooker, and its outer end penetrates through the outer shell and extends to the upper part of the outer shell. The main control circuit board of the cooker has a ring structure and is arranged around the power supply terminal, making the overall structure more compact.

[0016] An electric cooker protects a cooking container and the aforementioned electric cooker base, wherein the cooking container is detachably connected to the electric cooker base; the lower end of the electric cooker base is provided with a support enclosure, and when the cooking container is placed on the electric cooker base, the button area is located outside the coverage area of ​​the support enclosure.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] See Figures 1 to 5As shown, an electric cooker base includes a housing 11 and a touch control circuit board 21. The housing 11 serves as the external protective component of the electric cooker base, primarily protecting the internal electronic components from external moisture and dust, while also providing a support platform for user operation. The housing 11 has a button area 41, allowing users to control the electric cooker's functions, such as turning it on / off and adjusting the temperature, by pressing the button area 41. The housing 11 has an internal cavity for housing the touch control circuit board 21. This circuit board is a key component for receiving and processing user touch signals, converting user actions on the button area 41 into electrical signals to control the working state of the electric cooker.

[0027] The button area 41 has a planar or curved surface structure. When the button area 41 has a planar structure, an angle α is formed between the button area 41 and the touch control circuit board 21; when the button area 41 has a curved surface structure, an angle α is formed between the tangent plane of the center point of the button area 41 and the touch control circuit board 21, where α ∈ (0°, 90°). This angle setting allows the button area 41 to face the user at a suitable angle, facilitating user observation and operation, and improving ease of use. A cylindrical elastic sensor 22 is connected between the inner end face of the button area 41 and the touch control circuit board 21. This elastic sensor 22 functions when the user presses the button area 41. When the button area 41 is subjected to force, the elastic sensor 22 will deform, triggering the touch control circuit board 21 through this deformation, thereby converting mechanical pressure into an electrical signal. A limiting member 12 is provided on the inner end face of the button area 41. One end of the elastic sensor 22 is fixedly connected to the touch control circuit board 21, and the other end is sleeved around the limiting member 12 and abuts against the inner end face of the button area 41. The limiting member 12 can constrain the elastic sensing member 22. During the deformation of the elastic sensing member 22, it restricts its lateral displacement, allowing the elastic sensing member 22 to deform mainly in the axial direction, ensuring that it is in stable contact with the inner end face of the button area 41, so that the touch signal can be transmitted continuously and stably.

[0028] The button area 41 has two or more buttons, each corresponding to a different function of the electric cooker. For example, one button area 41 is used to control the power on / off of the appliance, another button area 41 can be used to adjust the temperature setting, and other button areas 41 can be used to set the timer function, etc. The multiple button areas 41 meet the diverse operating needs of users, allowing users to control the operating status of the electric cooker more precisely.

[0029] The inner end face of the outer casing 11 is provided with isolation ribs 13 between the button areas 41, which separate adjacent button areas 41. When a user presses a button area 41, the isolation ribs 13 prevent the electrical signal generated by the corresponding sensing spring of that button area 41 from interfering with the sensing spring of the adjacent button area 41. In this way, the signal transmission of each button area 41 is relatively independent, reducing the occurrence of accidental touches caused by mutual interference of electrical signals, and ensuring the effectiveness and accuracy of user operation.

[0030] The line connecting the button area 41 and the sensing spring on the touch control circuit board 21 is in the direction X, and the limiting member 12 extends in the direction Y. The angle β between the directions X and Y is (0°, 90°). This angle setting ensures that the constraint direction of the limiting member 12 on the sensing spring is not completely coincident with the direction of the spring force.

[0031] The end of the limiting member 12 is provided with a smooth portion, which can reduce the frictional force when the limiting member 12 contacts the elastic sensing element 22. When the elastic sensing element 22 deforms under force and moves relative to the limiting member 12, the smooth portion can prevent scratching or wear on the elastic sensing element 22, extend the service life of the elastic sensing element 22, and ensure that it can maintain good elasticity and signal transmission performance during long-term use.

[0032] The elastic sensing element 22 is a sensing spring, which transmits the pressure signal received by the button area 41 to the touch control circuit board 21. When the user presses the button area 41, the sensing spring, as a conductive medium, transmits the mechanical force to the circuit board through its own physical connection.

[0033] It also includes a main control circuit board for the cooker, which is integrated with the touch control circuit board 21. This integrated structure reduces the number of connection lines between circuit boards, lowering signal loss and interference during transmission. After the touch control circuit board 21 transmits the received user operation signals to the main control circuit board, the main control circuit board can quickly process these signals and control the heating power, heating time, and other operating parameters of the electric cooker according to a preset program, thus achieving effective control of various functions of the electric cooker.

[0034] It also includes a power supply terminal 23 connected to the cooker. The power supply terminal 23 is electrically connected to the main control circuit board of the cooker, and its outer end extends through the outer casing 11 to the upper part of the outer casing 11. The power supply terminal 23 is responsible for introducing electrical energy from an external power source into the electric cooker, providing power support for the operation of the entire device. The outer end of the power supply terminal 23 extends to the upper part of the outer casing 11, facilitating electrical connection with other parts of the cooker and ensuring that electrical energy can be smoothly transmitted to all components that require power. The main control circuit board of the cooker has a ring-shaped structure and is arranged around the power supply terminal 23. This layout allows the circuit board to make full use of the space inside the outer casing 11, making the entire base structure more compact and reducing space occupation while ensuring the normal operation of all components.

[0035] See Figure 4 As shown, an electric cooker includes a cooking container 31 and a base. The cooking container 31 is used to hold food and serves as the space for cooking. Users can place water, food, etc., in it, and rely on the heat provided by the base to complete cooking processes such as boiling, stewing, and braising. The cooking container 31 is detachably connected to the base, allowing users to easily remove and clean it before and after cooking. After cooking, users can easily remove the cooking container 31 from the base and serve it directly on the table for consumption, or clean it, improving ease of use. The lower end of the base has a support enclosure that supports and positions the cooking container 31. When the cooking container 31 is placed on the base, the support enclosure holds the bottom of the container, preventing it from sliding freely and ensuring that the container is stably positioned on the base, allowing heat to be effectively transferred to the food inside. Meanwhile, when the cooking container 31 is placed on the base of the electric cooker, the button area 41 is outside the coverage area of ​​the support enclosure. This ensures that the user's hand will not be obstructed by the cooking container 31 when operating the button area 41, nor will the button area 41 be covered by the cooking container 31 being placed on the base. The user can clearly see and operate the button area 41 at any time to adjust the working status of the electric cooker without worrying about accidentally touching the cooking container 31 and getting burned or affecting operation.
