Description

Technical Field

[0001] This utility model relates to the field of cooking pots, specifically a heat dissipation structure for the base of a cooking pot. Background Technology

[0002] Currently, the base of cooking pots has a structure similar to that described in Chinese patent document, application number 201921712556.8, which describes an improved heat dissipation structure for an electric stove. In this design, a cooking plate is installed inside the base, and a heat dissipation duct is provided within the mounting cavity corresponding to the cooking plate. Each heat dissipation duct has an air inlet, an air outlet, and a fan. The air inlet corresponds to the fan, and a guide shroud surrounds the fan. The guide shroud has several exhaust vents corresponding to the heat dissipation ducts. This structure allows the heat dissipation ducts to pass through the cooking plate in a roughly straight line. Therefore, some of the heat from the cooking plate radiates outwards to the base shell through the weaker side of the heat dissipation duct (the left and right sides of the airflow direction), resulting in poor heat dissipation and potentially causing high temperatures on the base surface. Therefore, the applicant has improved and perfected the base structure to simultaneously solve the above problems, providing a more suitable option for consumers. Utility Model Content

An air inlet is provided at the first end of the heat dissipation air duct on the base shell, and a fan is provided at the air inlet. An exhaust port is provided at the last end of the heat dissipation air duct on the base shell. The exhaust port is adjacent to the air inlet. The air is guided by the fan, drawn into the heat dissipation air duct through the air inlet, flows around the outer periphery of the entire heating coil, and is discharged through the exhaust port.

[0016] This utility model discloses a heat dissipation structure for the base of a cooking pot. This heat dissipation structure allows the airflow of the heat dissipation channel to surround the entire outer periphery of the heating ring, thereby carrying away the heat radiated from the inside out of the heating ring.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] See Figures 1 to 4 As shown, a heat dissipation structure for the base of a cooking pot includes a base shell 1 and a panel 2. The base shell 1 and the panel 2 are fixedly connected to each other, forming an installation cavity between them. A heating coil 3 is provided in the installation cavity. An inner air duct plate 4 is fixedly provided in the installation cavity, surrounding the heating coil 3. An annular heat dissipation air duct 5 is formed between the inner air duct plate 4 and the base shell 1. An air inlet 51 is provided at the first end of the heat dissipation air duct 5, and a fan 6 is provided at the air inlet 51. An exhaust port 52 is provided at the tail end of the heat dissipation air duct 5. The exhaust port 52 is adjacent to the air inlet 51. The exhaust port 52 is guided by the fan 6, and the air is drawn into the heat dissipation air duct 5 through the air inlet 51 and flows around the entire periphery of the heating coil 3, and is discharged through the exhaust port 52.

[0024] This heat dissipation structure mainly arranges the exhaust port 52 and the air inlet 51 close to each other, so that the air inlet 51 and the exhaust port 52 form a circular heat dissipation channel 5 as much as possible. This allows the airflow in the heat dissipation channel 5 to surround the entire outer circumference of the heating ring 3, thereby carrying away the heat radiated from the inside to the outside of the heating ring 3. This protects the electrical structure placed in the heat dissipation channel 5 from high temperature, which can improve the working life of the electrical structure. In addition, the heat dissipation channel 5 can also play a heat insulation role, preventing the heat from causing the outer surface of the base to become hot.

[0025] The heat dissipation duct 5 has a square groove structure. The air inlet 51 is opened on the bottom wall of the base shell 1 and is located at one corner of the square groove. The first shell wall 10 of the base shell 1 adjacent to the air inlet 51 has an exhaust port 52. The airflow blown out by the fan 6 is guided along the direction of the second shell wall 11 adjacent to the air inlet 51 of the base shell 1.

[0026] This structure places the air inlet 51 on the bottom wall, allowing the fan 6 to be laid horizontally, reducing the thickness of the base. It also allows the guided airflow to flow along the entire heat dissipation duct 5. The shape of the heat dissipation duct 5 leaves a relatively wide space at the corner position, which is convenient for installing the fan 6. This allows the base shell 1 to remain compact, reducing the longitudinal and transverse space of the base. Moreover, the exhaust port 52 only needs to be opened on any adjacent shell wall (the second shell wall 11 is chosen because it is on the rear end side of the base opposite to the second shell wall 11, which conforms to the conventional setting), thereby achieving an adjacent arrangement between the exhaust port 52 and the air inlet 51, making full use of the space of the heat dissipation duct 5.

[0027] The mounting cavity is also equipped with a main control board 7 electrically connected to the heating coil 3. The main control board 7 is installed in the heat dissipation duct 5 located inside the second shell wall 11. The airflow blown out by the fan 6 flows along the bottom of the main control board 7. In this embodiment, the main control board 7 is right next to the air outlet of the fan 6. The airflow just out of the air outlet has the fastest speed, so it can meet the heat dissipation requirements of the main control board 7, and the heat dissipation effect is the best, which is also in line with the ultimate purpose of the heat dissipation duct 5.

[0028] The mounting cavity is also provided with a control panel 71 electrically connected to the main control board 7. The control panel 71 is installed on the third shell wall 12 opposite to the first shell wall 10. At least a portion of the heat dissipation air duct 5 is defined between the back side of the control panel 71 and the inner air duct plate 4. While forming the heat dissipation air duct 5, the control panel 71 can be cooled by the airflow passing through its back side.

[0029] The mounting cavity is also provided with an outer air duct plate 8 fixed to the outside of the inner air duct plate 4. The outer air duct plate 8 and the adjacent shell wall of the base shell 1 form a heat insulation cavity 101, and the outer air duct plate 8 and the inner air duct plate 4 define at least a portion of the heat dissipation air duct 5. The outer air duct plate 8 prevents the shell wall of the base shell 1 from directly contacting the airflow of the heat dissipation air duct 5, which can play a heat insulation role, further reduce the heat transfer to the shell wall, and keep the outer surface of the base at a low temperature.

[0030] The inner wall of the base housing 1 extends around the air inlet 51 with an air guide shroud 13, which is located between the outer air duct plate 8 and the inner air duct plate 4. The fan 6 is fixed on the upper side of the air guide shroud 13, and the air intake of the fan 6 is directly opposite the air inlet 51.

[0031] The outer wall of the air guide shroud 13 extends to a partition 14 connected to the outer air duct plate 8 or the inner air duct plate 4. Through the cooperation of the air guide shroud 13 and the partition 14, the annular heat dissipation air duct 5 is broken and the beginning and end of the heat dissipation air duct 5 are formed. The beginning and end of the heat dissipation air duct 5 are separated by only one wall, minimizing the size of the gap in the heat dissipation air duct 5. The heat dissipation air duct 5 basically surrounds the entire heating ring.

[0032] The inner air duct plate 4 surrounds the heating cavity 102, and the heating coil 3 is installed inside the heating cavity 102. The inner air duct plate 4 has several connecting notches 41 on the circumferential direction that connect the heating cavity 102 and the heat dissipation air duct 5. The connecting notches 41 allow some of the heat from the heating coil 3 to dissipate from the inside to the outside. On the other hand, the heating coil mounting bracket 16 is installed on the base shell 1. The heating coil mounting bracket 16 can extend into the heating cavity 102 through the connecting notches 41 and be assembled and connected with the heating coil 3.

[0033] The rear end of the base shell 1 is recessed into a deep cavity 103. The rear cavity wall of the deep cavity 103 forms a first shell wall 10. The first shell wall 10 is tangent or nearly tangent to the inner air duct plate 4. Half of the exhaust port 52, 52a, is connected to the heat dissipation duct 5. The other half of the inner air duct plate 4, 52b, corresponding to the exhaust port 52, has a heat dissipation notch 42.

[0034] This structure brings the exhaust vent 52 closer to the inner air duct plate 4, allowing the heat emitted by the heating coil 3 to be discharged from the exhaust vent 52 more quickly and directly. However, this means that the airflow cannot cover the very end of the heat dissipation duct 5. Therefore, a heat dissipation notch 42 corresponding to the width of the other half of the exhaust vent 52 is opened on the inner air duct plate 4, so that the heat at this location can quickly pass through the heat dissipation notch 42 and the other half of the exhaust vent 52 to be discharged from the base.

[0035] See Figure 5 As shown, it also includes a power cord 9, which extends from the cavity of the deep cavity 103 to the outside of the base shell 1. A cover 15 is hinged to the opening of the deep cavity 103, forming a cable-concealing cavity between the cover 15 and the deep cavity 103. The cover 15 confines the coiled power cord 9 within the cable-concealing cavity. This structure conceals the power cord 9 within the cable-concealing cavity after it is coiled, thus storing the power cord and making the heating base in the cooking pot more aesthetically pleasing and compact.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
