Description

Technical Field

[0001] This utility model relates to the technical field of induction cookers, and in particular to an induction cooker base and an induction cooker. Background Technology

[0002] Induction cookers achieve efficient heating through the principle of electromagnetic induction. A high-frequency alternating current is passed through a coil inside the cooker, generating an alternating magnetic field. Eddy currents are induced in the bottom of the cookware within this magnetic field, generating Joule heating due to the material's resistance, thus achieving heating. During operation, the internal circuit modules generate significant heat, and the panel at the coil also requires heat dissipation. Current technology requires a cooling fan for each burner to achieve adequate cooling. However, for multi-burner induction cookers, a single cooling fan would require a high-powered fan to meet the cooling requirements, resulting in significant noise and a poor user experience. Furthermore, equipping each burner with a cooling fan would increase the overall manufacturing cost of the induction cooker. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Reference Figures 1 to 4According to a first aspect of the present invention, an induction cooker base includes a base body 100 and a support assembly. The base body 100 has a receiving groove 110. The support assembly is used to install a heating coil. The support assembly is disposed on the base body 100 and located in the receiving groove 110. The support assembly includes a first support 210 and a second support 220 spaced apart. The base body 100 is also provided with an air inlet 120, an air outlet 130, a first connecting part 140 and a second connecting part 150. The air inlet 120 and the first connecting part 140 are both generally located at the bottom of the first support 210. The first connecting part 140 is used to connect a cooling fan. The second connecting part 150 is located at the bottom of the second support 220 and is used to connect a circuit module. The air outlet 130 is located on the side wall of the receiving groove 110 adjacent to the second support 220. The air inlet 120 can draw in air, and the cooling fan connected to the first connecting part 140 blows air toward the first bracket 210 and the second bracket 220. The second connecting part 150 at the bottom of the second bracket 220 is equipped with a circuit module. Therefore, the two sets of coils that need to be cooled and the circuit module can be arranged in a compact manner, so that the above components can be fully cooled by a small cooling fan, which can save manufacturing costs while meeting the cooling requirements.

[0030] Specifically, the base body 100 is the lower base of the induction cooker. The receiving groove 110 is used to install components such as coils and circuit modules. A panel can be installed on the top of the base body 100 to support cookware. The receiving groove 110 contains a bracket assembly for supporting the coils. The induction cooker can have two burners: a first bracket 210 to support one coil and a second bracket 220 to support the other coil. An air inlet 120 can be provided on the bottom wall of the base body 100 at the bottom of the first bracket 210. A first connecting part 140 for installing a cooling fan can be provided at the air inlet 120. The first connecting part 140 can be a connecting post, and the cooling fan can be fixed to the connecting post with fasteners. The space at the bottom of the second bracket 220 can be used to support the circuit module. The second connecting part 150 can be a snap-fit ​​structure or a connecting post, and the circuit module can be securely connected to it. The air outlet 130 can be provided on the side wall of the receiving groove 110 along the direction from the first bracket 210 to the second bracket 220, so that the heat dissipation air duct can blow from the bottom of the first bracket 210 to the second bracket 220 and blow out from the side. It can dissipate heat from the coil of the first bracket 210, the coil of the second bracket 220 and the circuit module at the same time. In addition, the circuit module generates a lot of heat. Under the above structure, there is a ventilation gap between the circuit module and the coil of the second bracket 220 to facilitate ventilation, which can improve the heat dissipation efficiency. Only one cooling fan is needed to achieve efficient heat dissipation of the two burners, and the heat dissipation noise is low. It can save manufacturing costs while meeting the user's usage needs.

[0031] Reference Figure 1In some embodiments of this utility model, the middle part of the air inlet 120 is offset from the middle part of the first bracket 210, and the middle part of the air inlet 120 is positioned closer to the second bracket 220. In actual use, the circuit module generates a lot of heat, while the coil panel generates relatively little heat. Therefore, by offsetting the air inlet 120 from the first bracket 210, the air inlet 120 can be positioned closer to the circuit module, while also taking into account the coil at the first bracket 210. After offsetting the air inlet 120, the distance between the cooling fan and the circuit module can be shortened, thereby improving the heat dissipation effect of the circuit module without increasing the power of the cooling fan. It can be understood that the air inlet 120 only needs to have a portion at the bottom of the first bracket 210, and can be positioned as close to the circuit module as possible. Specifically, the first bracket 210 can be configured as four connecting columns, which are arranged at the four corners of a square. The center of the first bracket 210 is the midpoint of the square formed by the lines connecting the four connecting columns. The air inlet 120 can be circular, with the midpoint of the air inlet 120 being the midpoint of the circle. The air inlet 120 can be offset toward the second bracket 220 so that the midpoint of the air inlet 120 is misaligned with the midpoint of the first bracket 210.

[0032] Understandably, the second bracket 220 can also be configured as four connecting posts.

[0033] Reference Figures 1 to 3 In some embodiments of this utility model, the base body 100 is further provided with a partition plate 160, which is located on the outer periphery of the air inlet 120 and has an opening facing the second support 220. Specifically, by providing the partition plate 160, an air duct can be formed within the base body 100, and the area of ​​the air inlet 120 facing away from the air outlet 130 can be blocked by the partition plate 160. This prevents turbulence from forming within the receiving groove 110 after air enters the base body 100, and instead guides the airflow out through a predetermined heat dissipation path, thereby reducing noise and improving heat dissipation efficiency.

[0034] In some embodiments of this invention, the air inlet 120 has a louver structure. The louver structure can act as a barrier, reducing dust entry, and also allows the cooling fan to be concealed when viewed from the outside.

[0035] Reference Figures 1 to 4 In some embodiments of this utility model, the air outlet 130 extends downward to the bottom wall of the receiving groove 110. Specifically, the air outlet 130 can further extend to the bottom wall of the receiving groove 110 to expand the air outlet area, improve heat dissipation, and the air outlet direction can be directed towards the side and bottom. In actual use, if there is an obstruction on the side or bottom, air can also be discharged from another direction.

[0036] Reference Figures 1 to 4 In some embodiments of this utility model, the air outlet 130 is provided with a plurality of strip-shaped heat dissipation holes 131, which extend vertically and are closely spaced along the lateral side of the base. Specifically, the closely spaced strip-shaped heat dissipation holes 131 can prevent dust and insects from entering the induction cooker, and after the heat dissipation holes 131 extend to the bottom wall, the base body 100 can have a certain structural strength.

[0037] Reference Figures 1 to 4 In some embodiments of this utility model, a plurality of ribs 132 are provided at the air outlet 130, and the ribs 132 are disposed between each heat dissipation hole 131. Specifically, the ribs 132 can be set in an L-shape or a triangular shape, which can strengthen the support and enhance the strength of the base body 100 in the area of ​​the heat dissipation hole 131, and prevent the base from being deformed or damaged by collision during transportation.

[0038] Reference Figures 1 to 4 In some embodiments of this utility model, the base body 100 has a forward-extending protrusion 170 on its front side. The protrusion 170 is used for positioning and installation, and it can define a clearance space 300 between the protrusion 170 and the air outlet 130. Specifically, for an embedded induction cooker, the protrusion 170 can serve as a positioning structure, which can abut against the opening of the cabinet countertop for positioning. After installation, there is a clearance space 300 between the protrusion 170 and the air outlet 130, so that the air outlet 130 is not blocked by the cabinet side panel, allowing the air outlet 130 to dissipate air normally for heat dissipation. Furthermore, with the clearance space 300, the airflow is smoother, and the heat dissipation efficiency can be improved.

[0039] Reference Figure 3 In some embodiments of this utility model, two support components are provided, which are arranged alternately on the left and right. Specifically, it can be configured as a four-burner structure, and the support components can be arranged side by side and spaced apart on the base body 100, so that only two cooling fans are needed to achieve heat dissipation for the four-burner.

[0040] According to a second aspect of the present invention, an induction cooker includes an induction cooker using the aforementioned induction cooker base. By using the aforementioned induction cooker base, production costs can be reduced while meeting the heat dissipation and noise requirements of the induction cooker.
