Description

Technical Field

[0001] This utility model relates to the field of induction cookers, and in particular to an induction cooker with a sealed heat dissipation duct. Background Technology

[0002] During operation, the power board inside an induction cooker generates a significant amount of heat. To ensure proper functioning, induction cookers are typically designed with a fan blowing directly onto the power board for cooling, and numerous ventilation holes enhance airflow. However, since induction cookers are often installed in kitchen environments, they easily attract pests such as cockroaches, which can damage the power board. Furthermore, the oil and moisture commonly found in kitchens can be blown onto the power board by the fan, accelerating component aging, shortening the overall lifespan of the appliance, and significantly increasing the failure rate.

[0003] Based on the above, existing induction cookers need further improvement. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing induction cookers and provide an induction cooker with a sealed heat dissipation duct. By separating the power board outside the heat dissipation duct through the sealing component and the heat dissipation component, it can effectively prevent foreign objects such as oil fumes, water vapor, and pests from entering and affecting the operation of the power board, thereby improving the service life of the equipment and reducing the failure rate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an induction cooker with a sealed heat dissipation duct, comprising a cover plate, a body and a sealing component, wherein the cover plate covers the body and surrounds the body to form a receiving cavity, the sealing component is disposed in the receiving cavity and divides the receiving cavity into a heating cavity and a functional cavity, wherein a heat dissipation component and a heat dissipation duct are provided in the functional cavity, one side of the heat dissipation component is disposed in the heat dissipation duct, and the other side is connected to a power board.

[0006] This invention separates the power board from the heat dissipation duct through a sealing component and a heat dissipation component, effectively preventing foreign objects such as oil fumes, water vapor, and pests from entering and affecting the power board's operation. This ensures the stable operation of the power board, significantly extends the equipment's lifespan, and reduces the failure rate. Compared with existing technologies, this induction cooker with a sealed heat dissipation duct has significant advantages in overall reliability and lifespan.

[0007] Preferably, the main body includes a bottom shell, an air guide plate, and an impeller cover. The bottom shell is a recessed cavity with an open top and an air inlet and an air outlet. The impeller cover surrounds the upper side of the air inlet. One end of the air guide plate is connected to the impeller cover, and the other end surrounds the air outlet. The heat dissipation assembly is disposed on the air guide plate. The sealing assembly, the impeller cover, the heat dissipation assembly, and the inner wall of the bottom shell form the heat dissipation duct. The air inlet and the air outlet are surrounded by the sealing assembly, the impeller cover, the heat dissipation assembly, and the inner wall of the bottom shell to form the heat dissipation duct. Air enters from the air inlet, flows through the heat dissipation duct, dissipates heat from the heat dissipation assembly, and finally exits from the air outlet. At the same time, the power board connected to the other side of the heat dissipation assembly is isolated from the heat dissipation duct to prevent external pollutants from entering and affecting the operation of the power board.

[0008] Preferably, the sealing assembly includes a separator and a sealing cover. The separator has a notch, and the impeller cover passes through the notch and surrounds the separator to form a communication opening. The sealing cover seals the communication opening. The impeller cover and the sealing assembly together separate and seal the heating chamber to prevent the heat from the heating chamber from being transferred to the functional chamber, which would cause the power board to heat up rapidly and be damaged.

[0009] Preferably, the heat dissipation component includes a heat dissipation aluminum block and a heat dissipation aluminum plate. The heat dissipation aluminum block is disposed on the air guide plate, and the heat dissipation aluminum plate is disposed on the underside of the heat dissipation aluminum block and the power board. The heat generated by the power board is guided to the heat dissipation aluminum block through the heat dissipation aluminum plate. The heat dissipation aluminum block is placed on the air guide plate. When the airflow passes through the heat dissipation aluminum block, it can carry away the heat to achieve heat dissipation and cooling of the power board.

[0010] Preferably, a fan wheel is provided on the upper side of the air inlet, and the fan wheel cover surrounds the fan wheel; the fan wheel is used to draw air into the heat dissipation duct.

[0011] Preferably, the heat dissipation aluminum block is provided with several air guides on the side near the heat dissipation air duct. The air guides are evenly distributed along the height direction of the heat dissipation aluminum block, and air guide grooves are formed between the air guides. After the heat is conducted to the heat dissipation aluminum block, it is distributed in parts on each air guide. The air guide grooves form semi-independent heat dissipation air ducts, which can accelerate the heat dissipation efficiency and improve the heat dissipation effect.

[0012] Preferably, a connecting part extends outward from one side of the functional cavity, the connecting part is placed inside the heating cavity, and a control plate is provided on the connecting part for controlling the induction cooker.

[0013] Preferably, the air outlet is located on the lower side of the connecting part.

Detailed Implementation

[0026] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "horizontal", "inner", and "outer" is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing this utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0027] See Figures 1 to 7This embodiment discloses an induction cooker 1 with a sealed heat dissipation duct, including a cover plate 2, a body 3 and a sealing component 4. The cover plate 2 covers the body 3 and surrounds the body to form a receiving cavity 31. The sealing component 4 is disposed in the receiving cavity 31 and divides the receiving cavity 31 into a heating cavity 5 and a functional cavity 6. The functional cavity 6 is provided with a heat dissipation component 7 and a heat dissipation duct 8. One side of the heat dissipation component 7 is disposed in the heat dissipation duct 8, and the other side is connected to a power board 35.

[0028] To form a heat dissipation duct 8, the main body 3 includes a bottom shell 32, an air guide plate 38, and a fan cover 34. The bottom shell 32 is a recessed cavity with an open top and an air inlet 321 and an air outlet 322. The fan cover 34 surrounds the upper side of the air inlet 321. One end of the air guide plate 38 is connected to the fan cover 34, and the other end surrounds the air outlet 322. The heat dissipation component 7 is disposed on the air guide plate 38. The sealing component 4, the fan cover 34, the heat dissipation component 7, and the inner wall of the bottom shell 32 surround and form the heat dissipation duct 8.

[0029] The sealing assembly 4 includes a partition plate 41 and a sealing cover 42. The partition plate 41 has a notch 411. The impeller cover 34 passes through the notch 411 and surrounds the partition plate 41 to form a communication opening 412. The sealing cover 42 seals the communication opening 412. In this solution, the sealing assembly 4, the impeller cover 34, and the partition plate 41 together form a sealed isolation for the heating chamber 5, preventing heat from the heating chamber 5 from being conducted to the functional chamber 6, which would cause the power board 35 to heat up rapidly and affect the service life of the power board 35.

[0030] To achieve heat conduction between the heating cavity 5 and the functional cavity 6, the partition 41 is specifically a mica sheet.

[0031] The heat dissipation assembly 7 includes a heat dissipation aluminum block 71 and a heat dissipation aluminum plate 72. The heat dissipation aluminum block 71 is disposed on the air guide plate 38, and the heat dissipation aluminum plate 72 is disposed on the underside of the heat dissipation aluminum block 71 and the power board 35. In this design, the power board 35 conducts heat to the heat dissipation duct 8 through the heat dissipation aluminum plate 72 for heat dissipation, thus preventing the power board 35 from overheating and affecting its service life.

[0032] See Figure 8 The heat dissipation aluminum block 71 has several air guide sections 711 on the side near the heat dissipation duct 8. The air guide sections 711 are evenly distributed along the height direction of the heat dissipation aluminum block 71, and air guide grooves 712 are formed between the air guide sections 711. In this design, the air guide sections 711 distribute the heat on the heat dissipation aluminum block 71 to different areas, and the air guide grooves 712 dissipate the heat in adjacent areas. This method of distributing heat from a large area to smaller areas can improve heat dissipation efficiency.

[0033] See Figures 1 to 7A connecting portion 36 extends outward from one side of the functional cavity 6. The connecting portion 36 is placed inside the heating cavity 5. A control panel 361 is provided on the connecting portion 36 for controlling the induction cooker. Specifically, the air outlet 322 is located on the lower side of the connecting portion 36.

[0034] A filter board 37 is provided on one side of the power board 35.

[0035] The heating chamber 5 is equipped with a heating coil disk 51. Specifically, there are four heating coil disks 51.

[0036] The air inlet 321 is circular, and the air outlet 322 is strip-shaped.

[0037] This invention uses a sealing component 4 and a heat dissipation component 7 to separate the power board 35 outside the heat dissipation duct 8, effectively preventing foreign objects such as oil fumes, water vapor, and pests from entering and affecting the operation of the power board 35. This ensures the stable operation of the power board 35, significantly extends the service life of the equipment, and reduces the failure rate. Compared with existing technologies, the induction cooker 1 with a sealed heat dissipation duct of this invention has significant advantages in overall reliability and service life.
