Description

Technical Field

[0001] This utility model relates to the field of induction cooker technology, and in particular to an induction cooker with a novel air duct structure. Background Technology

[0002] As users increasingly demand space utilization and thinner, thinner induction cookers have appeared on the market.

[0003] In related technologies, as the thickness of induction cookers is reduced, the limited shell space imposes significant limitations on the heat dissipation of internal components or electronic devices. In other words, currently thinner induction cookers generally cannot effectively meet the heat dissipation requirements of internal components or electronic devices. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an induction cooker with a novel air duct structure, which is beneficial for improving the heat dissipation efficiency of internal components.

[0005] This utility model embodiment of an induction cooker with a novel air duct structure includes: a bottom shell having an upward-opening receiving groove, the receiving groove communicating with an air inlet and an air outlet; a fan connected to the bottom shell, the upper end and / or lower end of the fan respectively having an air inlet communicating with the air inlet, and the fan having a first air outlet and a second air outlet communicating with the air outlet; a coil connected to the bottom of the receiving groove and disposed on the air outlet side of the first air outlet; a radiator connected to the bottom of the receiving groove and disposed on the air outlet side of the second air outlet; and an air guiding assembly including... The bottom of the receiving groove is connected to a first air guide plate and a second air guide plate. One end of the first air guide plate extends to the edge of the first air outlet away from the second air outlet, and the other end extends towards the side wall of the receiving groove. One end of the second air guide plate extends to the edge of the second air outlet away from the first air outlet, and the other end extends to the side wall of the receiving groove. The first air guide plate and the second air guide plate together with the bottom shell form an air inlet cavity and an air outlet cavity. The air inlet cavity is connected to the air inlet, and the air outlet cavity is connected to the air outlet. The circuit board is connected to the heat sink and is located in the air outlet cavity.

[0006] The induction cooker with a novel air duct structure according to an embodiment of the present invention has at least the following beneficial effects: The bottom shell has an upward-facing receiving groove, and the fan, coil, radiator, circuit board, and air guide assembly are all connected within the receiving groove. The fan is connected to the bottom of the receiving groove, the coil is connected to the bottom of the receiving groove and located on the air outlet side of the first air outlet, and the radiator is connected to the bottom of the receiving groove and located on the air outlet side of the second air outlet. The upper and / or lower ends of the fan are provided with air inlets to increase the air intake and exhaust volume. When the fan operates, the first air outlet of the fan can blow airflow towards the coil, and the second air outlet of the fan can blow airflow towards the radiator. That is, air cooling of the coil, radiator, and circuit board can be achieved simultaneously through a single fan. One end of the first air guide plate extends to the edge of the first air outlet, and the other end extends towards the side wall of the receiving groove. One end of the second air guide plate extends to the edge of the second air outlet, and the other end extends towards the side wall of the receiving groove. Extending from one end to the side wall of the receiving groove, the first air guide plate can constrain the airflow from the first air outlet, and the second air guide plate can constrain the airflow from the second air outlet. This reduces airflow turbulence and eddies, thereby increasing the air pressure directed towards the coil or radiator. The first air guide plate, the second air guide plate, and the bottom shell together form an air inlet chamber and an air outlet chamber. The separation between the first and second air guide plates increases the separation between the air inlet chamber and the air outlet chamber, facilitating the separation of cold air entering the air inlet chamber from the air inlet and hot air exiting the air outlet chamber from the air outlet. This reduces the mixing of cold and hot air, thereby improving the heat dissipation efficiency of internal components and quickly lowering their temperature. In other words, the addition of air guide components to the induction cooker with the new air duct structure improves the heat dissipation efficiency of internal components and reduces the limitations imposed by heat dissipation on the design thickness of the induction cooker with the new air duct structure.

[0007] According to some embodiments of the present invention, the induction cooker with the novel air duct structure also includes a partition plate connected to the bottom of the receiving groove, the partition plate being disposed between the first air outlet and the second air outlet.

[0008] According to some embodiments of the present invention, the first air guide plate is bent around the coil.

[0009] According to some embodiments of the present invention, the induction cooker with the novel air duct structure also includes an air guide strip connected to the bottom of the accommodating groove. One end of the air guide strip is located on the air outlet side of the first air outlet, and the other end bends and extends toward the side wall of the accommodating groove. The coil is mounted on the air guide strip, so that a through first air outlet space is constructed between the lower end of the coil and the bottom of the accommodating groove. The first air outlet space is connected to the first air outlet and the exhaust port.

[0010] According to some embodiments of the present invention, the induction cooker with the novel air duct structure also includes a cover plate covering the upper end of the bottom shell, and a second air outlet space is constructed between the upper end of the coil and the cover plate, and the second air outlet space is connected to the first air outlet and the exhaust port.

[0011] According to some embodiments of the present invention, a first air inlet space is constructed between the upper end of the fan and the cover plate, and a second air inlet space is constructed between the lower end of the fan and the bottom of the receiving groove. The upper end and the lower end of the fan are respectively provided with air inlets, and the first air inlet space and the second air inlet space are respectively connected to the two air inlets.

[0012] According to some embodiments of the present invention, the induction cooker with the novel air duct structure further includes a first air guide plate, one end of which is connected to the surface of the first air guide plate facing the coil, and the other end extends and bends toward the coil.

[0013] According to some embodiments of the present invention, the first air guide plate is disposed on the side of the first air guide plate near the first air outlet.

[0014] According to some embodiments of the present invention, the lower edge of the first air guide plate is connected to the bottom of the receiving groove.

[0015] According to some embodiments of the present invention, the induction cooker with the novel air duct structure further includes a second air guide plate connected to the bottom of the receiving groove. One end of the second air guide plate is disposed opposite to the first air outlet, and the other end extends and bends toward the coil.

[0033] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0034] Reference Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an induction cooker with a novel air duct structure, comprising a cover plate, a bottom shell 100, a fan 200, a coil 300, a radiator 700, a circuit board 920, and an air guide assembly.

[0035] Reference Figure 1 and Figure 2As shown, the bottom shell 100 has an upward-facing receiving groove 110, which provides a receiving space for components such as the fan 200, coil 300, radiator 700, circuit board 920, and air guide assembly. The cover plate is connected to the upper end of the bottom shell 100 to close the upper opening of the receiving groove 110. The cover plate and the bottom shell 100 together form a receiving cavity surrounding the fan 200, coil 300, radiator 700, circuit board 920, and air guide assembly. The cover plate and the bottom shell 100 can protect the components such as the fan 200, coil 300, radiator 700, circuit board 920, and air guide assembly.

[0036] Reference Figure 1 and Figure 2 As shown, the side wall of the receiving trough 110 is connected to an air inlet 120 and an air outlet 130. A fan 200 is connected to the bottom of the receiving trough 110 and is connected to both the air inlet 120 and the air outlet 130. When the fan 200 operates, the rotation of its impeller drives external airflow into the receiving trough 110 through the air inlet 120, and the airflow within the receiving trough 110 is blown out through the air outlet 130. The fan 200 has air inlets at its upper and lower ends, respectively, connected to the air inlet 120. This allows the fan 200 to adopt a structure that allows air to enter from both the upper and lower sides simultaneously, increasing the air intake volume and thus improving the air output volume and air pressure on the outlet side.

[0037] The fan 200 has a first air outlet 210 and a second air outlet 220. Specifically, the fan 200 can be a vortex fan 200, that is, the air inlet of the fan 200 is located in the axial direction of the impeller, and the first air outlet 210 and the second air outlet 220 of the fan 200 are located in the tangential direction of the impeller rotation direction, so as to improve the air pressure and air speed of the blown air.

[0038] Reference Figure 1 and Figure 2As shown, the coil 300 is connected to the bottom of the receiving groove 110. After the coil 300 is connected to an external power source, the coil 300 can generate a high-frequency alternating magnetic field. This high-frequency alternating magnetic field passes through the cover plate and acts on the bottom of the pot, inducing eddy currents inside the metal of the pot bottom. The resistance of the pot converts the eddy currents into Joule heat to heat the pot. The heat from the pot is transferred in the opposite direction to the coil 300, resulting in a large amount of heat in the coil 300. The fan 200 has a first air outlet 210 and a second air outlet 220. The coil 300 of the induction cooker with the novel air duct structure is located on the air outlet side of the first air outlet 210 of the fan 200, so that the airflow blown by the fan 200 from the first air outlet 210 can directly blow onto the coil 300. The radiator 700 is located on the air outlet side of the second air outlet 220 of the fan 200, so that the airflow blown by the fan 200 from the second air outlet 220 can directly blow onto the radiator 700.

[0039] Compared to induction cookers that use two fans 200 to cool the coil 300 and radiator 700 respectively, this induction cooker with a novel air duct structure uses one fan 200 to cool both the coil 300 and radiator 700 simultaneously. Specifically, the fan 200 has a first air outlet 210 and a second air outlet 220, which are respectively positioned opposite to the coil 300 and radiator 700. This allows for cooling of both the coil 300 and the radiator 700, as well as the circuit board 920, while effectively reducing the space occupied within the receiving slot 110. This avoids the problem of increased size of the bottom shell 100 due to the need for two fans 200.

[0040] Reference Figure 1 and Figure 2 As shown, to address the heat dissipation requirements of internal components, this induction cooker with a novel air duct structure is equipped with an air guiding component. Specifically, the air guiding component includes a first air guiding vane 510 and a first air guiding plate 400 connected to the bottom of the receiving groove 110. One end of the first air guiding plate 400 is connected to the edge of the first air outlet 210, and the other end extends towards the side wall of the receiving groove 110. The first air guiding plate 400 is curved around the coil 300, meaning that the first air guiding plate 400 can serve as a boundary for airflow, constraining the airflow flowing out from the first air outlet 210. The arrangement of the first air guiding plate 400 can reduce airflow turbulence and reduce airflow eddies, thereby increasing the air pressure of the airflow blowing towards the coil 300.

[0041] Reference Figure 1 and Figure 2As shown, one end of the first air guide vane 510 is connected to the surface of the first air guide plate 400 facing the coil 300, while the other end is bent towards the coil 300. The surface of the first air guide vane 510 facing the first air outlet 210 is the first air guiding arc surface. The first air guide vane 510 can redirect the airflow flowing to the first air guide plate 400, so that the airflow flowing from the first air outlet 210 to the first air guide plate 400 is guided along the first air guiding arc surface to the coil 300. That is, the induction cooker with the novel air duct structure, through the cooperation of the first air guide plate 400 and the first air guide vane 510, can make the airflow blown from the first air outlet 210 more concentrated towards the coil 300, thus further enhancing the guiding effect on the airflow and improving the heat dissipation efficiency of the coil 300, thereby quickly reducing the temperature of the coil 300.

[0042] The induction cooker with a novel air duct structure also includes a second air guide plate 600 located on the side of the fan 200 away from the first air guide plate 400. One end of the second air guide plate 600 is connected to the fan 200, and the other end of the second air guide plate 600 extends toward the side wall of the receiving groove 110. The first air guide plate 400 and the second air guide plate 600 together with the bottom shell 100 form an air inlet cavity 111 and an air outlet cavity 112. The air inlet cavity 111 is connected to the air inlet 120, and the air outlet cavity 112 is connected to the air outlet 130.

[0043] Reference Figure 1 and Figure 2 As shown, components such as coil 300, radiator 700 and heating element 910 are all located inside exhaust cavity 112.

[0044] Reference Figure 1 and Figure 2 As shown, specifically, the ends of the second air guide plate 600 and the first air guide plate 400 away from the side wall of the receiving groove 110 are both connected to the fan 200, so that the receiving groove 110 is divided into an air inlet chamber 111 and an air outlet chamber 112. The fan 200 is located at the junction of the air inlet chamber 111 and the air outlet chamber 112, so that the fan 200 can absorb the cold air in the air inlet chamber 111 and blow the airflow into the air outlet chamber 112. As the airflow passes through the coil 300, radiator 700, heating element 910, electronic components on the circuit board 920 and other components in the air outlet chamber 112, hot air is formed. Finally, the hot air is discharged from the air outlet 130.

[0045] Reference Figure 1 and Figure 2 As shown, the induction cooker with a novel air duct structure can improve the separation between the air inlet chamber 111 and the air outlet chamber 112 by setting the first air guide plate 400 and the second air guide plate 600, which helps to reduce the problem of reduced heat dissipation efficiency caused by the mixing of cold air and hot air.

[0046] Reference Figure 1 and Figure 2 As shown, specifically, the first air guide plate 400 and the second air guide plate 600 are arranged vertically. The upper end of the first air guide plate 400 extends to the upper wall of the receiving groove 110, and the lower end extends to the end of the first air outlet 210 of the fan 200 away from the second air outlet 220. The lower end of the second air guide plate 600 extends to the right side wall of the receiving groove 110, and the upper end extends to the end of the second air outlet 220 of the fan 200 away from the first air outlet 210, so that the receiving groove 110 is divided into an air inlet chamber 111 and an air outlet chamber 112.

[0047] Reference Figure 1 and Figure 2 As shown, compared with traditional induction cookers, the induction cooker with a novel air duct structure provided in this embodiment of the utility model is equipped with an air guiding component, which is beneficial to improve the heat dissipation efficiency of the coil 300 and the radiator 700. It can reduce the limitation on the design thickness of the induction cooker with the novel air duct structure caused by the heat dissipation of the coil 300 and the radiator 700, so that the thickness of the bottom shell 100 and the cover plate can be designed to be thinner, in order to meet the user's pursuit of space utilization and product thinness.

[0048] It should be understood that in some other embodiments, the fan 200 has an air inlet only at the upper or lower end.

[0049] Reference Figure 1 and Figure 2 As shown, it can be understood that in this embodiment, the induction cooker with the novel air duct structure also includes a partition plate 800 connected to the bottom of the receiving groove 110. The partition plate 800 is disposed between the first air outlet 210 and the second air outlet 220 to enhance the effect of separating and constraining the airflow, so that the airflow flowing out of the first air outlet 210 can be blown more concentratedly towards the coil 300 to improve the heat dissipation efficiency of the coil 300. The airflow flowing out of the second air outlet 220 can be blown more concentratedly towards the radiator 700, the heating element 910, and the electronic components on the circuit board 920 to improve the heat dissipation efficiency of the radiator 700, the heating element 910, and the electronic components on the circuit board 920.

[0050] Reference Figure 1 and Figure 2 As shown, specifically, the two ends of the circuit board 920 can extend to the coil 300 and the heat sink 700 respectively, so that most of the airflow blown out from the first air outlet 210 and the second air outlet 220 can eventually flow through the circuit board 920, thereby driving the heat of the electronic components on the circuit board 920, so as to improve the heat dissipation efficiency of the induction cooker with the new air duct structure, and make the body of the induction cooker with the new air duct structure more lightweight and thinner.

[0051] Reference Figure 1 and Figure 2 As shown, it can be understood that the induction cooker with the novel air duct structure also includes at least two air guides 530 connected to the bottom of the accommodating groove 110. One end of the air guide 530 is located on the air outlet side of the first air outlet 210, and the other end bends and extends toward the side wall of the accommodating groove 110. The coil 300 is mounted on the two air guides 530, so that a through first air outlet space 140 is constructed between the lower end of the coil 300 and the bottom of the accommodating groove 110. The first air outlet space 140 is connected to the first air outlet 210 and the exhaust port 130.

[0052] Reference Figure 1 and Figure 2 As shown, the coil disk 300 is positioned between two air guide strips 530, forming a first air outlet space 140 at the lower end of the coil disk 300. This increases the heat dissipation area and air pressure of the coil disk 300, thereby improving the heat dissipation efficiency of the coil disk 300. It also effectively reduces the heat transferred from the coil disk 300 to the bottom shell 100, thereby reducing the heat resistance requirements of the bottom shell 100 and lowering the manufacturing cost of the bottom shell 100.

[0053] Reference Figure 1 and Figure 2 As shown, the air guide strip 530 is connected to the bottom of the receiving groove 110, with one end located on the air outlet side of the first air outlet 210 and the other end bent towards the side wall of the receiving groove 110. The air guide strip 530 can guide the airflow at the bottom of the air outlet area of ​​the fan 200, thereby guiding the airflow at the bottom of the receiving groove 110 to the coil 300 for heat dissipation at the lower end of the coil 300. This induction cooker with a novel air duct structure can improve the heat dissipation efficiency of the coil 300 through three-dimensional heat dissipation of the coil 300.

[0054] It should be understood that in some other embodiments, the air guide strip 530 may be provided with 1 strip, 3 strips, 4 strips, etc., and the number of air guide strips 530 is not limited here.

[0055] Reference Figure 1 and Figure 2 As shown, it can be understood that in this embodiment, a second air outlet space is constructed between the upper end of the coil disk 300 and the cover plate. The second air outlet space is connected to the first air outlet 210 and the exhaust port 130. That is, the upper end of the coil disk 300 can be provided with a gap for airflow to pass through. The airflow blown out from the first air outlet 210 can dissipate heat from the upper end of the coil disk 300.

[0056] Reference Figure 1 and Figure 2As shown, after the fan 200 operates, the airflow blown out from the first air outlet 210 can flow over the upper surface, lower surface and circumference of the coil disk 300, thereby dissipating heat from the coil disk 300 in all directions and effectively improving the heat dissipation efficiency of the coil disk 300.

[0057] Reference Figure 1 and Figure 2 As shown, it can be understood that a first air inlet space is constructed between the upper end of the fan 200 and the cover plate, and a second air inlet space is constructed between the lower end of the fan 200 and the bottom of the receiving groove 110. Both the first and second air inlet spaces are connected to the first air outlet 210. The two air inlets are named the first air inlet and the second air inlet, respectively. The first air inlet of the fan 200 is connected to the first air inlet space, and the second air inlet is connected to the second air inlet space.

[0058] Reference Figure 1 and Figure 2 As shown, the fan 200 of the induction cooker with the novel air duct structure can adopt a structure of simultaneous air intake from the top and bottom to increase the air intake volume of the fan 200, thereby increasing the air output volume and air pressure of the first air outlet 210, thereby improving the heat dissipation efficiency of the coil 300, thereby reducing the limitation of the coil 300 on the design thickness of the induction cooker with the novel air duct structure, so that the bottom shell 100 and cover plate of the induction cooker with the novel air duct structure can be designed to be thinner and lighter.

[0059] Reference Figure 1 and Figure 2 As shown, it can be understood that the first air guide vane 510 is located on the side of the first air guide plate 400 near the first air outlet 210, because the air pressure and velocity of the airflow located near the first air outlet 210 are greater. This air guiding assembly places the first air guide vane 510 on the side of the first air guide plate 400 near the first air outlet 210 to enhance the guiding effect on the airflow, so that the airflow with higher air pressure and velocity can flow along the first guiding arc surface of the first air guide vane 510 to the coil 300. The position design of the first air guide vane 510 can enhance the guiding effect on the airflow, thereby improving the heat dissipation efficiency of the coil 300.

[0060] Reference Figure 1 and Figure 2 As shown, the lower edge of the first air guide 510 is connected to the bottom of the receiving groove 110, that is, the lower edge of the first air guide 510 is attached to the bottom wall of the receiving groove 110, which can enhance the constraint effect on the airflow located at the bottom of the receiving groove 110. The position design of the first air guide 510 can enhance the guiding effect on the airflow, thereby improving the heat dissipation efficiency of the coil 300.

[0061] Reference Figure 1 and Figure 2As shown, it should be noted that the first air guide slab 510 and the first air guide plate 400 can be integrally molded parts to improve the connection stability between the first air guide plate 400 and the first air guide slab 510, and eliminate the positioning and assembly problems of the first air guide slab 510 and the first air guide plate 400.

[0062] It should be understood that in some other embodiments, there is a gap between the lower edge of the first air guide 510 and the bottom of the receiving groove 110, that is, the first air guide 510 is suspended.

[0063] Reference Figure 1 and Figure 2 As shown, it can be understood that in this embodiment, the induction cooker with the novel air duct structure also includes a second air guide 520 connected to the bottom of the receiving groove 110. One end of the second air guide 520 is disposed opposite to the first air outlet 210, and the other end extends and bends toward the coil 300.

[0064] Reference Figure 1 and Figure 2 As shown, the second air guide 520 can be in the form of a thin sheet; specifically, the second air guide 520 is an arc-shaped bent sheet. The airflow blowing out from the first air outlet 210 can flow along the shape of the second air guide 520. The surface of the second air guide 520 facing the first air outlet 210 is the second air guide arc surface. The second air guide 520 is arranged opposite to the first air outlet 210 so that the airflow can flow along the second air guide arc surface. This can more directly and effectively change the direction of the airflow blowing out from the first air outlet 210, so that the airflow is more concentrated and blown onto the coil 300, thereby improving the heat dissipation efficiency of the coil 300 and quickly removing the heat from the coil 300.

[0065] Reference Figure 1 and Figure 2 As shown, the first air guide vane 510 is mainly used to change the airflow direction in the edge area of ​​the fan 200's outlet area, and the second air guide vane 520 is mainly used to change the airflow direction at the first air outlet 210 port of the fan 200's outlet area. This induction cooker with a novel air duct structure, through the cooperation of the first air guide vane 510 and the second air guide vane 520, allows the airflow to be more concentrated and directed towards the coil 300, thereby improving the heat dissipation efficiency of the coil 300.

[0066] Reference Figure 1 and Figure 2 As shown, specifically, the second air guide 520 is located between the two air guide strips 530, which can enhance the guidance of the air outlet area of ​​the fan 200 at the port of the first air outlet 210, so that most of the airflow is guided to the coil 300.

[0067] Reference Figure 1 and Figure 2As shown, the first air guide plate 400, the first air guide vane 510, one of the air guide strips 530, the second air guide vane 520 and the other air guide strip 530 are arranged from left to right.

[0068] The first air guide plate 400, the first air guide vane 510, the second air guide vane 520, and the air guide strip 530 are all arranged in a clockwise direction from the first air outlet 210 towards the upper right of the bottom shell 100. That is, the overall air guiding direction of the first air guide plate 400, the first air guide vane 510, the second air guide vane 520, and the air guide strip 530 is consistent, which helps to reduce airflow turbulence and eddies, thereby improving the concentration of airflow.

[0069] Reference Figure 1 and Figure 2 As shown, specifically, the induction cooker with the novel air duct structure also includes a heating element 910 and a circuit board 920. The heating element 910 can be a bridge rectifier or a transistor, etc. The heating element 910 can be connected to the heat sink 700, thereby transferring the heat it generates to the heat sink 700. Through the air cooling effect of the fan 200, the heat sink 700 and the heating element 910 are quickly cooled down. The circuit board 920 is connected to the side of the heat sink 700 away from the second air outlet 220, and the side of the heating element 910 away from the heat sink 700 is connected to the circuit board 920 to facilitate the power supply and control of the heating element 910 by the circuit board 920.

[0070] Reference Figure 1 and Figure 2 As shown, the left side wall of the air inlet chamber 111 has multiple air inlets 120 arranged in the front-to-back direction, while the front wall of the exhaust chamber 112 has multiple exhaust outlets 130 arranged in the left-to-right direction, and the right side wall of the exhaust chamber 112 has multiple exhaust outlets 130 arranged in the front-to-back direction. That is, air enters the air inlet chamber 111 from the left side of the bottom shell 100. Driven by the fan 200, the airflow is exhausted from the front and right sides of the bottom shell 100. This can better control the airflow inlet and exhaust, and help reduce the problem of reduced heat dissipation efficiency caused by the mixing of cold air and hot air.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
