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 heat dissipation 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, especially for heating elements that generate a lot of heat. 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 heat dissipation structure, which is beneficial for improving the heat dissipation efficiency of the heating element.

[0005] The induction cooker with a novel heat dissipation structure according to this utility model embodiment includes: a bottom shell having an upward-opening receiving groove, the receiving groove being connected to an air inlet and an air outlet; a fan connected to the bottom of the receiving groove, the fan being connected to the air inlet and the air outlet, the fan having a first air outlet; a radiator connected to the bottom of the receiving groove and located on the air outlet side of the first air outlet, the radiator including a base plate and multiple heat dissipation fins connected to the upper part of the base plate, the multiple heat dissipation fins being parallel to each other and all being set at an angle to the base plate, two adjacent heat dissipation fins and the base plate together forming a heat dissipation air duct, the extension direction of the heat dissipation air duct being consistent with the mainstream air outlet direction of the first air outlet; and a heating element connected to the upper part of the base plate, the heating element being positioned opposite to the end of the multiple heat dissipation air ducts away from the fan.

To improve the heat dissipation efficiency of the radiator, after the fan starts operating, the airflow blown out from the first air outlet can be diverted into multiple heat dissipation ducts. Through the contact between the airflow and the heat dissipation fins, the heat of the heat dissipation fins can be quickly carried away. Moreover, the heating element is set opposite to the end of the multiple heat dissipation ducts away from the fan, that is, some airflow passes through the heat dissipation ducts and blows directly onto the heating element to quickly reduce the temperature of the heating element. In other words, the induction cooker with the new heat dissipation structure improves the heat dissipation efficiency of the radiator and heating element through the duct design and the connection structure between the radiator and the heating element, which can reduce the limitations on the design thickness of the induction cooker with the new heat dissipation structure.

[0010] According to some embodiments of the present invention, the two first air guide plates are parallel to each other, and the length direction of the first air guide plates is consistent with the extension direction of the heat dissipation air duct.

[0011] According to some embodiments of the present invention, the induction cooker with the novel heat dissipation structure further includes a cover plate covering the upper end of the bottom shell, 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, and both the first air inlet space and the second air inlet space are connected to the first air outlet.

One end of the second air guide plate extends to the side wall of the accommodating groove, and the other end of the second air guide plate is connected to a fan, so that the accommodating groove is divided into an air inlet chamber and an air outlet chamber. The air inlet chamber is connected to the air inlet, and the air outlet chamber is connected to the air outlet.

[0033] Reference Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an induction cooker with a novel heat dissipation structure, comprising a cover plate, a bottom shell 100, a fan 200, a radiator 300, and a heating element 400.

[0034] Reference Figure 1 and Figure 2 As shown, the bottom shell 100 has an upward-facing accommodating groove 110. A cover plate is connected to the upper end of the bottom shell 100 to close the upper opening of the accommodating groove 110. The accommodating groove 110 provides installation space for components such as the fan 200, radiator 300, and heating element 400. The side wall of the accommodating groove 110 is connected to an air inlet 120 and an air outlet 130 to facilitate the exchange of air between the accommodating groove 110 and the outside air.

[0035] Reference Figure 1 and Figure 2As shown, the fan 200 is connected to the bottom of the receiving groove 110. Specifically, the fan 200 can be a vortex fan, that is, the fan 200 takes in air axially and exits air tangentially from the impeller of the fan 200. The air inlet side of the fan 200 is connected to the air inlet 120, and the air outlet side of the fan 200 is provided with a first air outlet 210. After the external air flows through the air inlet 120 and the air inlet side of the fan 200, it can be blown out from the first air outlet 210. The first air outlet 210 is located in the tangential direction of the impeller of the fan 200. The following explanation takes the main air outlet direction of the first air outlet 210 as an example of air outlet from left to right.

[0036] Reference Figure 1 and Figure 2 As shown, specifically, considering that the heating element 400 will generate a large amount of heat, the induction cooker with the new heat dissipation structure connects the heating element 400 to the radiator 300, and the radiator 300 is located on the air outlet side of the first air outlet 210, that is, the airflow flowing out of the first air outlet 210 blows directly to the radiator 300 to quickly remove the heat dissipated by the radiator 300, so as to improve the heat dissipation efficiency of the heating element 400 connected to the radiator 300.

[0037] Reference Figure 1 and Figure 2 As shown, the radiator 300 includes a base plate 310 and multiple heat dissipation fins 320 connected to the upper end of the base plate 310. The heat dissipation fins 320 are arranged at right angles to the base plate 310, and the lower ends of the heat dissipation fins 320 are connected to the base plate 310. The multiple heat dissipation fins 320 are parallel to each other, and two adjacent heat dissipation fins 320 and the base plate 310 together form a heat dissipation duct 330, that is, the multiple heat dissipation ducts 330 are parallel to each other. Moreover, the extension direction of the heat dissipation duct 330 is consistent with the mainstream air outlet direction of the first air outlet 210, that is, the extension direction of the heat dissipation duct 330 is arranged in the left and right direction, which helps to reduce the obstruction of the airflow from the first air outlet 210 by the heat dissipation duct 330 of the radiator 300. The heating element 400 is connected to the upper end of the base plate 310, and the heating element 400 is positioned opposite the end of the multiple heat dissipation ducts 330 away from the fan 200.

[0038] Reference Figure 1 and Figure 2 As shown, compared to the traditional induction cooker where the heating element 400 is connected to the lower end of the radiator 300, the induction cooker with a novel heat dissipation structure provided in this embodiment connects the heating element 400 to the upper end of the radiator 300, so that the lower end of the base plate 310 can fit against the bottom of the receiving groove 110, allowing the heat dissipation fins 320 to make full use of the space along the thickness direction of the receiving groove 110, which is beneficial to increasing the setting height of the heat dissipation air duct 330, thereby improving the heat dissipation efficiency of the radiator 300.

[0039] Reference Figure 1 and Figure 2 As shown, after the fan 200 operates, the airflow blown out from the first air outlet 210 can be diverted into multiple heat dissipation air ducts 330. Through the contact between the airflow and the heat dissipation fins 320, the heat of the heat dissipation fins 320 can be quickly removed. The heating element 400 and the end of the multiple heat dissipation air ducts 330 away from the fan 200 are arranged opposite each other, that is, some airflow passes through the heat dissipation air ducts 330 and blows directly onto the heating element 400 to quickly reduce the temperature of the heating element 400.

[0040] Reference Figure 1 and Figure 2 As shown, the induction cooker with the new heat dissipation structure, through the air duct design and the connection structure between the heat sink 300 and the heating element 400, is conducive to improving the heat dissipation efficiency of the heat sink 300 and the heating element 400. It can reduce the limitation on the design thickness of the heat sink 300 and the heating element 400 of the induction cooker with the new heat dissipation structure, so that the thickness of the bottom shell 100 and the cover plate can be designed to be thinner and lighter, in order to meet the user's pursuit of space utilization and product thinness.

[0041] Reference Figure 1 and Figure 2 As shown, it should be noted that the heating electrical component can be a bridge rectifier or a transistor, etc. Specifically, the heat sink fins 320 and the base plate 310 are integrally molded parts, and both the heat sink fins 320 and the base plate 310 are made of metal materials to improve the thermal conductivity of the heat sink fins 320 and the base plate 310.

[0042] Reference Figure 1 and Figure 2 As shown, it can be understood that the heat dissipation duct 330 is open upwards, that is, it is open to the left, right, or upwards. Compared to radiators where the heat dissipation duct 330 is partially covered by a cover, this induction cooker with a novel heat dissipation structure can eliminate the problem of the cover of a traditional radiator 300 blocking airflow into the heat dissipation duct 330 by allowing the heat dissipation duct 330 to open upwards. This also helps to improve the airflow efficiency of the heat dissipation duct 330 and the heat dissipation efficiency of the radiator 300.

[0043] It should be understood that in some other embodiments, the heat dissipation duct 330 is open upwards, and when the cover plate is connected to the upper end of the bottom shell 100, the upper opening of the cover plate closes the heat dissipation duct 330, so that the heat dissipation duct 330 is connected from left to right, which helps to reduce the eddies generated by the airflow passing through the heat dissipation duct 330.

[0044] Reference Figure 1 and Figure 2As shown, it can be understood that in this embodiment, the upper surface of the base plate 310 is provided with a mounting area 340, which is located on the side of the base plate 310 away from the fan 200, that is, the mounting area 340 is located on the right side of the base plate 310. The heating element 400 is connected within the mounting area 340, while a portion of the heat dissipation duct 330 is disposed opposite to the mounting area 340, and a portion of the heat dissipation duct 330 is disposed around the side of the mounting area 340.

[0045] Reference Figure 1 and Figure 2 As shown, specifically, a portion of the heat dissipation duct 330 is located on the left side of the mounting area 340, so that the airflow passing through this portion of the heat dissipation duct 330 blows directly into the mounting area 340 to remove the heat from the heating element 400 located in the mounting area 340, thereby achieving rapid cooling of the heating element 400. Another portion of the heat dissipation duct 330 extends from the left end to the right end of the base plate 310, and this portion of the heat dissipation duct 330 is located on the front or rear side of the mounting area 340, to fully utilize the upper space of the base plate 310 to arrange the heat dissipation ducts 330, thus increasing the number of heat dissipation ducts 330 and improving the heat dissipation efficiency of the radiator 300.

[0046] Reference Figure 1 and Figure 2 As shown, it can be understood that in order to enhance the constraint on the airflow from the fan 200 at the first air outlet 210, the induction cooker with the novel heat dissipation structure also includes two first air guide plates 500. The two first air guide plates 500 are respectively located on both sides of the first air outlet 210 along the long side direction, that is, the two first air guide plates 500 are respectively connected to the front and rear sides of the first air outlet 210. The first air guide plates 500 extend from left to right, and the two first air guide plates 500 together with the bottom plate 310 form an air outlet channel.

[0047] Reference Figure 1 and Figure 2 As shown, the radiator 300 is located between the two first air guide plates 500, that is, the radiator 300 is located in the air outlet channel. The induction cooker with the new heat dissipation structure can enhance the constraint of the airflow from the first air outlet 210 through the setting of the two first air guide plates 500, which is conducive to improving the air pressure and air speed of the airflow blown out from the first air outlet 210, and avoiding the problem of airflow running around or vortex increasing, which would affect the heat dissipation performance.

[0048] Reference Figure 1 and Figure 2As shown, the two first air guide plates 500 are parallel to each other, and the length direction of the first air guide plate 500 is consistent with the extension direction of the heat dissipation duct 330. The induction cooker with the novel heat dissipation structure can enhance the constraint on the airflow from the first air outlet 210 through the first air guide plate 500, and make the airflow from the first air outlet 210 pass through the heat dissipation duct 330 more smoothly, so as to improve the heat dissipation efficiency of the radiator 300 and the heating element 400.

[0049] Reference Figure 1 and Figure 2 As shown, the induction cooker with the novel heat dissipation structure also includes a support frame. The lower end of the support frame is connected to the bottom of the receiving groove 110, and the upper end of the support frame is connected to the fan 200, so that a second air intake space is constructed between the lower end of the fan 200 and the bottom of the receiving groove 110, while a first air intake space is constructed between the upper end of the fan 200 and the cover plate. The upper end of the fan 200 is provided with a first air inlet communicating with the first air intake space, and the lower end is provided with a second air inlet communicating with the second air intake space.

[0050] Reference Figure 1 and Figure 2 As shown, the fan 200 of the induction cooker with the novel heat dissipation 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, so as to improve the heat dissipation efficiency of the radiator 300 and the heating element 400, thereby reducing the limitation on the design thickness of the induction cooker with the novel heat dissipation structure caused by the radiator 300 and the heating element 400, so that the bottom shell 100 and the cover plate of the induction cooker with the novel heat dissipation structure can be designed to be thinner and lighter.

[0051] Reference Figure 1 and Figure 2 As shown, it can be understood that the induction cooker with the novel heat dissipation structure also includes a coil 600 connected to the bottom of the accommodating slot 110. In order to take into account the heat dissipation of the coil 600, the fan 200 also includes a second air outlet 220, and the coil 600 is located on the air outlet side of the second air outlet 220.

[0052] Reference Figure 1 and Figure 2As shown, compared to induction cookers that use two fans 200 to dissipate heat from the coil 600 and the radiator 300 respectively, this induction cooker with a novel heat dissipation structure uses one fan 200 to dissipate heat from both the coil 600 and the radiator 300 simultaneously. Specifically, the fan 200 has a first air outlet 210 and a second air outlet 220, which are respectively positioned opposite to the radiator 300 and the coil 600. This allows for heat dissipation of both the radiator 300 and the coil 600, effectively reducing the space occupied within the receiving slot 110 and avoiding the problem of increased size of the bottom shell 100 due to the need for two fans 200.

[0053] Reference Figure 1 and Figure 2 As shown, it can be understood that one of the first air guide plates 500 is disposed between the first air outlet 210 and the second air outlet 220 to enhance the function 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 radiator 300 and the heating element 400, thereby improving the heat dissipation efficiency of the radiator 300 and the heating element 400, and so that the airflow flowing out of the second air outlet 220 can be blown more concentratedly towards the coil 600, thereby improving the heat dissipation efficiency of the coil 600.

[0054] Reference Figure 1 and Figure 2 As shown, it can be understood that the induction cooker with the novel heat dissipation structure also includes at least two second air guide plates 700 connected to the bottom of the accommodating slot 110. One end of the second air guide plate 700 extends to the side wall of the accommodating slot 110, and the other end of the second air guide plate 700 is connected to the fan 200, so that the accommodating slot 110 is divided into an air inlet chamber 111 and an air outlet chamber 112. The air inlet chamber 111 is connected to the air inlet 120, and the air outlet chamber 112 is connected to the air outlet 130.

[0055] Reference Figure 1 and Figure 2 As shown, components such as the coil 600, radiator 300, and heating element 400 are all located inside the exhaust cavity 112.

[0056] Reference Figure 1 and Figure 2As shown, specifically, the end of the second air guide plate 700 away from the side wall of the receiving groove 110 can be connected to the fan 200 or the first air guide plate 500, 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 600, radiator 300 and heating element 400 and other components in the air outlet chamber 112, hot air is formed. Finally, the hot air is discharged from the air outlet 130.

[0057] Reference Figure 1 and Figure 2 As shown, the induction cooker with the novel heat dissipation structure can enhance the separation between the air inlet chamber 111 and the air outlet chamber 112 by setting the second air guide plate 700, which helps to reduce the problem of reduced heat dissipation efficiency caused by the mixing of cold air and hot air.

[0058] Specifically, the two second air guide plates 700 are arranged vertically. The upper end of the upper second air guide plate 700 extends to the upper wall of the receiving groove 110, and the lower end extends to the end of the second air outlet 220 of the fan 200 away from the first air outlet 210. The lower end of the lower second air guide plate 700 extends to the right side wall of the receiving groove 110, and the upper end extends to the end of the first air guide plate 500 connected to the end of the first air outlet 210 of the fan 200 away from the second air outlet 220, so that the receiving groove 110 is divided into an air inlet chamber 111 and an air outlet chamber 112.

[0059] Reference Figure 1 and Figure 2 As shown, it can be understood that the induction cooker with the novel heat dissipation structure also includes a circuit board 800 connected to the bottom of the receiving slot 110. The circuit board 800 is connected to the heating element 400 and is located on the side of the radiator 300 away from the fan 200.

[0060] Reference Figure 1 and Figure 2 As shown, the circuit board 800 is located at the right end of the receiving groove 110. The right end of the heating element 400 can extend out of the mounting area 340 and connect to the circuit board 800. The two ends of the circuit board 800 can extend to the heat sink 300 and the coil 600 respectively, so that the airflow blown by the fan 200 from the first air outlet 210 and the second air outlet 220 can mostly flow through the circuit board 800 after passing through the heat sink 300 and the coil 600, so as to remove the heat dissipated by the electronic components on the circuit board 800 and improve the heat dissipation efficiency of the induction cooker with the new heat dissipation structure.

[0061] Reference Figure 1 and Figure 2As shown, it can be understood that, specifically, the rear end of the receiving groove 110 of the bottom shell 100 is provided with a control area. The control area is mainly used to house the display component and touch component, etc., for the user to operate the induction cooker with the new heat dissipation structure. Under the separation of the first air guide plate 500 and the second air guide plate 700, the receiving groove 110 is divided into an air inlet chamber 111 located on the left and an air outlet chamber 112 located on the right.

[0062] 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.

[0063] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. 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.
