Utility Model Content

[0003] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0004] In view of this, the utility model proposes a cooking device, including: a heating plate, a display panel, and a control panel; a shell body, which is connected to the heating plate, a cavity is formed between the shell body and the heating plate, the shell body is provided with an air inlet and an air outlet, the air inlet and the air outlet are connected with the cavity; a fan, the fan is located in the cavity, the air inlet and the fan are arranged opposite to each other, and the fan has an exhaust port; a first air duct, which is located in the cavity, one end of the first air duct is connected with the exhaust port, and a display panel is provided on the path of the first air duct; a second air duct, which is located in the cavity, one end of the second air duct is connected with the exhaust port, the first air duct and the second air duct are connected with the air outlet, and a control panel is provided on the path of the second air duct.

[0005] When the shell is connected to the heating plate, the fan is located in the cavity between the shell and the heating plate. For example, the control panel can also be installed in the cavity to prevent the control panel from being damaged by bumps. The display panel needs to realize the display function. A part of the display panel can be arranged in the cavity, and the other part of the display panel extends out of the cavity to perform the display function.

[0006] An exhaust port is provided on the fan, and an air inlet and an air outlet are provided on the shell. The air inlet is arranged opposite to the fan. When the fan is running, external air flow is sucked into the fan through the air inlet. A first air duct and a second air duct are formed in the cavity. The exhaust port and the air outlet are both connected to the first air duct, and the exhaust port and the air outlet are both connected to the second air duct. The air flow blown out by the fan can flow into the first air duct and the second air duct through the exhaust port.

[0007] The display panel is located on the extension path of the first air duct, and the airflow in the first air duct will flow through the display panel, and the airflow will take away the heat on the surface of the display panel, thereby realizing the heat dissipation function of the display panel, and the airflow in the first air duct is discharged to the outside through the air outlet to prevent heat from accumulating inside the cavity. The control panel is located on the extension path of the second air duct, and the airflow in the second air duct will flow through the control panel, and the airflow will take away the heat on the surface of the control panel, thereby realizing the heat dissipation function of the control panel, and the heat in the second air duct is discharged to the outside through the air outlet.

[0008] By cooperating with the fan, the first air duct and the second air duct, the control panel and the display panel can be cooled during the operation of the cooking device, thereby avoiding overheating of the control panel and the display panel, ensuring the operating stability of the control panel and the display panel, reducing the damage rate of the control panel and the display panel, and avoiding functional failure of the control panel and the display panel.

[0009] In addition, the cooking device in the above technical solution provided by the utility model may also have the following additional technical features:

[0010] In some technical solutions, optionally, the cooking device also includes: a partition located in the cavity, the partition divides the exhaust outlet into a first sub-outlet and a second sub-outlet, the first sub-outlet is connected to one end of the first air duct, and the second sub-outlet is connected to one end of the second air duct.

[0011] A partition is provided on the air outlet of the fan, and the partition is used to separate the space where the air outlet is located, so that the air outlet is divided into a first sub-air outlet and a second sub-air outlet. A part of the airflow blown out by the fan is blown into the first air duct through the first sub-air outlet, and another part of the airflow blown out by the fan is blown into the second air duct through the second sub-air outlet. By dividing the air outlet into two parts, the two parts of the airflow are blown into the first air duct and the second air duct respectively. In this case, the opening area of ​​the first sub-air outlet and the second sub-air outlet can be set according to demand, and the airflow blown out of the air outlet can be equally divided into the first air duct and the second air duct, or more airflow can be blown into the first air duct or the second air duct to meet the heat dissipation effect of the control panel and the display panel.

[0012] In some technical solutions, optionally, the opening area of ​​the second sub-air vent is greater than or equal to the opening area of ​​the first sub-air vent.

[0013] During the operation of the cooking equipment, the heat generated by the control panel is usually greater than the heat generated by the display panel. In this case, the partition can be set to offset to the first sub-air vent, thereby reducing the opening area of ​​the first sub-air vent and increasing the opening area of ​​the second sub-air vent. The opening area of ​​the second sub-air vent is made larger than the opening area of ​​the first sub-air vent, and the airflow blown out by the fan flows more into the second air duct. By reasonably allocating the air flow in the first air duct and the second air duct, it is beneficial to improve the heat dissipation effect of the control panel, avoid a large temperature rise of the control panel, and ensure the operating stability of the control panel.

[0014] In some technical solutions, optionally, the air outlet includes a first air outlet and a second air outlet, the first air outlet is connected to the first air duct, and the second air outlet is connected to the second air duct.

[0015] The housing is provided with a first air outlet and a second air outlet, and the airflow in the first air duct is discharged through the first air outlet, and the airflow in the second air duct is discharged through the second air outlet, that is, separate air outlets are provided for the first air duct and the second air duct, respectively. Since the first air outlet and the second air outlet are independent of each other, the first air outlet and the second air outlet are spaced apart, and the first air duct and the second air duct have different air outlet positions, so that the two air outlets of the first air duct and the second air duct are prevented from interfering with each other, thereby ensuring the stability of airflow discharge.

[0016] In some technical solutions, optionally, there are multiple second air outlets, and the multiple second air outlets are distributed in sequence along the extension direction of the second air duct, and the distances between the multiple second air outlets and the heating plate decrease successively in the direction away from the exhaust port.

[0017] A plurality of second air outlets are arranged on the housing, and the plurality of second air outlets are distributed in a stepped manner. In a direction away from the air outlet, that is, the flow direction of the airflow in the second air duct, in this direction, the spacing between the plurality of second air outlets and the heating plate decreases successively, so that the height of the plurality of second air outlets compared to the bottom surface of the housing increases successively.

[0018] When the air flow flows in the second air duct, the air flow will gradually pass through multiple second air outlets with successively increasing heights, so that more air flow can be blown out of the second air outlet in a straight line, which is beneficial to increase the discharge speed of the air flow, thereby avoiding the air flow from circulating inside the second air duct. The air flow can effectively bring the heat of the control board out of the cavity, thereby ensuring the heat dissipation effect of the control board.

[0019] In some technical schemes, optionally, the first air duct includes: a first sub-air duct, a first end of the first sub-air duct is connected to the exhaust port; a second sub-air duct, a first end of the second sub-air duct is connected to the second end of the first sub-air duct, at least a portion of the display panel is located on the path of the second sub-air duct, the second sub-air duct and the display panel extend in the same direction, and an angle is set between the first sub-air duct and the second sub-air duct.

[0020] The display panel has a display function, so the display panel usually needs to be set on the side of the heating plate. When the fan cannot blow the airflow directly to the display panel, the first air duct can be set to a structure with an angle. Among them, the first sub-air duct and the second sub-air duct are connected, and the first sub-air duct is connected to the exhaust port. At least a part of the display panel is located on the path of the second sub-air duct. In order to increase the contact time between the airflow and the display panel, the second sub-air duct is set to extend in the same direction as the display panel. When the airflow flows in the second sub-air duct, the airflow in the second sub-air duct can continue to contact the display panel, which is beneficial to improve the heat dissipation effect of the display panel.

[0021] In some technical solutions, optionally, the first air duct further includes: a third sub-air duct, a first end of the third sub-air duct is connected to the second end of the second sub-air duct, an air outlet is connected to the third sub-air duct, and an angle is set between the third sub-air duct and the second sub-air duct.

[0022] In the case that the air outlet and the display panel are misaligned, the air outlet and the second sub-air duct may be connected via the third sub-air duct.

[0023] After the airflow and the display panel dissipate heat, the temperature of the airflow rises, connecting the air outlet with the third sub-air duct. An angle is set between the third sub-air duct and the second sub-air duct, so that the air outlet can be moved away from the display panel to avoid the airflow discharged from the shell from contacting the display panel, thereby preventing the high-temperature airflow from affecting the stable operation of the display panel.

[0024] In some technical solutions, optionally, the cooking device further includes: an air guide bracket connected to the heating plate, and the air guide bracket is provided with a first air duct and a second air duct.

[0025] The air guide bracket is machined with a first air duct and a second air duct. When the air guide bracket is installed on the heating plate, the air duct structure on the air guide bracket faces the exhaust port and the air outlet. Therefore, there is no need to set the air duct structure on the heating plate and the shell, and there is no need to make major changes to the structure of the heating plate and the shell, which is beneficial to improving the processing convenience of the air duct structure.

[0026] In some technical solutions, optionally, an installation cavity is provided on the air guide bracket, the fan is located in the installation cavity, and a portion of the air guide bracket is distributed along the circumference of the air outlet.

[0027] An installation cavity is formed on the air guide bracket, and the fan is installed in the installation cavity. The installation cavity protects the fan. In this case, the air guide bracket can separate the fan from other components to avoid mutual interference between different components, and also prevent the fan from being bumped by other components, thereby reducing the damage rate of the fan.

[0028] A portion of the air guide bracket is distributed along the circumference of the exhaust port, that is, in this case, the air guide bracket can prevent the airflow in the first air duct and the second air duct from flowing into the installation cavity, ensuring that the airflow can flow stably into the first air duct and the second air duct, avoiding the airflow from circulating in the installation cavity, which is beneficial to improving the heat dissipation effect of the control panel and the display panel.

[0029] In some technical solutions, optionally, the partition is integrally provided with the air guide bracket.

[0030] When processing the air guide bracket, the partition is directly processed on the air guide bracket, so that the partition and the air guide bracket are an integrated structure. After the air guide bracket is installed, the partition is located at the exhaust port. Therefore, there is no need to install the partition separately, which is beneficial to improving the assembly convenience of the cooking equipment and reducing the number of parts inside the cooking equipment, which is beneficial to improving processing convenience and reducing processing costs.

[0031] In some technical solutions, optionally, the control panel is located in the opening direction of the exhaust port.

[0032] The control panel is arranged in the opening direction of the air outlet so that the air flow blown out by the fan can directly blow toward the control panel.

[0033] Specifically, the heat generated by the control panel is usually greater than the heat generated by the display panel. By placing the control panel in the opening direction of the exhaust port, the airflow does not need to turn but blows directly to the control panel, which is beneficial to improving the heat dissipation efficiency of the control panel and ensuring the operating stability of the control panel.

[0034] In some technical solutions, optionally, the first side of the control panel faces the exhaust port, the second side of the control panel is a side adjacent to the first side of the control panel, and the display panel is located on the second side of the control panel.

[0035] The first side of the control panel and the second side of the control panel are two adjacent sides of the control panel. The first side of the control panel faces the exhaust port, and the display panel is located on the second side of the control panel. Therefore, the display panel is adjacent to the exhaust port. The airflow discharged from the exhaust port passes through the display panel after flowing a short distance. At this time, the airflow maintains a high flow rate, which is beneficial to improve the heat dissipation effect of the display panel.

[0036] In some technical solutions, optionally, at least a portion of the first air duct is located on one side of the control panel.

[0037] On the one hand, the wind discharged from the exhaust port can be blown directly to the control panel. On the other hand, the heat is further dissipated through the auxiliary effect of the first air duct, which is beneficial to improve the heat dissipation effect of the control panel. At the same time, the wind from the first air duct can dissipate heat for the display panel. The display panel and the fan are arranged at a distance to reduce the influence of motor vibration on the display panel.

[0038] In some technical solutions, optionally, the distance between the air outlet and the control panel is smaller than the distance between the air outlet and the display panel.

[0039] The distance between the exhaust port and the control board is small, and the distance between the exhaust port and the control board is large, so the airflow can reach the control board quickly. The heat generated by the control board is usually greater than the heat generated by the display board. By reducing the distance between the exhaust port and the control board, it is beneficial to improve the heat dissipation efficiency of the control board and ensure the operating stability of the control board.

[0040] In some technical solutions, optionally, an air inlet is provided on the shell, the air inlet is provided on the air inlet, the area of ​​the air inlet is S1, the area of ​​the fan's direct projection on the shell is S2, and 0.8×S1≤S2≤1.2×S1.

[0041] An air inlet is arranged in the area where the air inlet portion is located, and the area of ​​the air inlet portion is relatively close to the projection area of ​​the fan, thereby ensuring that the fan can smoothly inhale external air, which is beneficial to improving the driving effect of the fan on the airflow.

[0042] In some technical solutions, optionally, the display panel and the control panel are both connected to the heating disk.

[0043] The display panel and the control panel are arranged on the heating plate. When the shell is disassembled and assembled, the display panel and the control panel will not interfere with the disassembly and assembly process of the shell, thereby improving the convenience of disassembly and assembly of the shell.

[0053] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0054] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0055] Refer to the following Figures 1 to 5 The present invention describes a cooking device provided according to some embodiments of the present invention.

[0056] Combination Figure 1 , Figure 2 and Figure 5 As shown, in an embodiment of the utility model, a cooking device is proposed, including: a heating plate 100, a display panel 200, a control panel 300, a housing 400, a fan 500, a first air duct 610 and a second air duct 620. The heating plate 100 is connected to the housing 400, and a cavity 410 is formed between the housing 400 and the heating plate 100 (it should be noted that Figure 5 It is only used to show that a cavity structure can be formed between the housing 400 and the heating plate 100. The shapes of the housing 400 and the heating plate 100 are not affected. Figure 5The housing 400 is provided with an air inlet 420 and an air outlet 430, and the air inlet 420 and the air outlet 430 are connected to the cavity 410. The fan 500 is located in the cavity 410, and the air inlet 420 is arranged opposite to the fan 500. The fan 500 has an air outlet 510. The first air duct 610 and the second air duct 620 are located in the cavity 410. One end of the first air duct 610 is connected to the air outlet 510. A display panel 200 is provided on the path of the first air duct 610, and one end of the second air duct 620 is connected to the air outlet 510. The first air duct 610 and the second air duct 620 are connected to the air outlet 430. A control panel 300 is provided on the path of the second air duct 620.

[0057] When the shell 400 is connected to the heating plate 100, the fan 500 is located in the cavity 410 between the shell 400 and the heating plate 100. By way of example, the control board 300 can also be installed in the cavity 410 to prevent the control board 300 from being damaged by bumps. The display panel 200 needs to realize a display function. A part of the display panel 200 can be arranged to be located in the cavity 410, and another part of the display panel 200 extends out of the cavity 410 to perform a display function.

[0058] The fan 500 is provided with an exhaust port 510, and the housing 400 is provided with an air inlet 420 and an air outlet 430. The air inlet 420 is arranged opposite to the fan 500. During the operation of the fan 500, the external air flow is sucked into the fan 500 through the air inlet 420. A first air duct 610 and a second air duct 620 are formed in the cavity 410. The exhaust port 510 and the air outlet 430 are both connected to the first air duct 610, and the exhaust port 510 and the air outlet 430 are both connected to the second air duct 620. The air flow blown out by the fan 500 can flow into the first air duct 610 and the second air duct 620 through the exhaust port 510.

[0059] The display panel 200 is located on the extension path of the first air duct 610. The airflow in the first air duct 610 will flow through the display panel 200, and the airflow will take away the heat on the surface of the display panel 200, thereby achieving the heat dissipation function of the display panel 200. The airflow in the first air duct 610 is discharged to the outside through the air outlet 430 to prevent heat from accumulating inside the cavity 410. The control panel 300 is located on the extension path of the second air duct 620. The airflow in the second air duct 620 will flow through the control panel 300, and the airflow will take away the heat on the surface of the control panel 300, thereby achieving the heat dissipation function of the control panel 300. The heat in the second air duct 620 is discharged to the outside through the air outlet 430.

[0060] By cooperating with the fan 500, the first air duct 610 and the second air duct 620, heat dissipation of the control panel 300 and the display panel 200 can be achieved during the operation of the cooking device, thereby preventing the control panel 300 and the display panel 200 from being overheated, ensuring the operating stability of the control panel 300 and the display panel 200, reducing the damage rate of the control panel 300 and the display panel 200, and avoiding functional failure of the control panel 300 and the display panel 200.

[0061] In a possible application, the display panel 200 and the control panel 300 can be fixed to the heating plate 100 by locking or welding. Similarly, the fan 500 can also be fixed to the heating plate 100 by locking or welding. The housing 400 and the heating plate 100 can be connected by a locking or snap-fit ​​structure.

[0062] Combination Figure 1 and Figure 2 As shown, in some embodiments, optionally, the cooking device also includes: a partition 700, the partition 700 is located in the cavity 410, the partition 700 divides the exhaust outlet 510 into a first sub-outlet 511 and a second sub-outlet 512, the first sub-outlet 511 is connected to one end of the first air duct 610, and the second sub-outlet 512 is connected to one end of the second air duct 620.

[0063] A partition 700 is provided on the air outlet 510 of the fan 500. The partition 700 is used to separate the space where the air outlet 510 is located, so that the air outlet 510 is divided into two parts, the first sub-air outlet 511 and the second sub-air outlet 512. A part of the airflow blown out by the fan 500 is blown into the first air duct 610 through the first sub-air outlet 511, and another part of the airflow blown out by the fan 500 is blown into the second air duct 620 through the second sub-air outlet 512. By dividing the air outlet 510 into two parts, the two parts of the airflow are blown into the first air duct 610 and the second air duct 620 respectively. In this case, the opening areas of the first sub-air outlet 511 and the second sub-air outlet 512 can be set according to requirements, and the airflow blown out of the air outlet 510 can be equally divided and flow into the first air duct 610 and the second air duct 620, or more airflow can be blown into the first air duct 610 or the second air duct 620, so as to meet the heat dissipation effect of the control board 300 and the display board 200.

[0064] In some embodiments, optionally, the opening area of ​​the second sub-air vent 512 is greater than or equal to the opening area of ​​the first sub-air vent 511 .

[0065] During the operation of the cooking equipment, the heat generated by the control panel 300 is usually greater than the heat generated by the display panel 200. In this case, the partition 700 can be set to be offset toward the first sub-vent 511, thereby reducing the opening area of ​​the first sub-vent 511 and increasing the opening area of ​​the second sub-vent 512. The opening area of ​​the second sub-vent 512 is made larger than the opening area of ​​the first sub-vent 511, and the airflow blown out by the fan 500 flows more into the second air duct 620. By reasonably allocating the air flow rates in the first air duct 610 and the second air duct 620, it is beneficial to improve the heat dissipation effect of the control panel 300, avoid a large temperature rise of the control panel 300, and ensure the operating stability of the control panel 300.

[0066] Combination Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, optionally, the air outlet 430 includes a first air outlet 431 and a second air outlet 432 , the first air outlet 431 is connected to the first air duct 610 , and the second air outlet 432 is connected to the second air duct 620 .

[0067] The housing 400 is provided with a first air outlet 431 and a second air outlet 432. The airflow in the first air duct 610 is discharged through the first air outlet 431, and the airflow in the second air duct 620 is discharged through the second air outlet 432, that is, separate air outlets 430 are provided for the first air duct 610 and the second air duct 620, respectively. Since the first air outlet 431 and the second air outlet 432 are independent of each other, the first air outlet 431 and the second air outlet 432 are arranged at intervals, and the first air duct 610 and the second air duct 620 have different air outlet positions, so that the two air outlets of the first air duct 610 and the second air duct 620 are prevented from interfering with each other, thereby ensuring the stability of airflow discharge.

[0068] Combination Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, optionally, the number of the second air outlet 432 is multiple, and the multiple second air outlets 432 are arranged along the extension direction of the second air duct 620 ( Figure 1 As shown in the arrow pointing to A in the middle, the second air outlets 432 are distributed in sequence, and the distances between the plurality of second air outlets 432 and the heating plate 100 decrease in sequence as they move away from the air outlet 510.

[0069] A plurality of second air outlets 432 are provided on the housing 400, and the plurality of second air outlets 432 are distributed in a stepped manner. In the direction away from the exhaust port 510, that is, the flow direction of the airflow in the second air duct 620, in this direction, the spacing between the plurality of second air outlets 432 and the heating plate 100 decreases successively, and therefore, the height of the plurality of second air outlets 432 increases successively compared to the bottom surface of the housing 400.

[0070] When the air flow flows in the second air duct 620, the air flow will gradually pass through multiple second air outlets 432 with successively increasing heights, so that more air flow can be blown out of the second air outlet 432 in a straight line, which is beneficial to increase the discharge speed of the air flow, thereby avoiding the air flow from circulating inside the second air duct 620. The air flow can effectively bring the heat of the control board 300 out of the cavity 410, thereby ensuring the heat dissipation effect of the control board 300.

[0071] Combination Figure 1 and Figure 2 As shown, in some embodiments, optionally, the first air duct 610 includes: a first sub-air duct 611 and a second sub-air duct 612, the first end of the first sub-air duct 611 is connected to the exhaust port 510, the first end of the second sub-air duct 612 is connected to the second end of the first sub-air duct 611, at least a portion of the display panel 200 is located in the second sub-air duct 612, the second sub-air duct 612 extends in the same direction as the display panel 200, and an angle is set between the first sub-air duct 611 and the second sub-air duct 612.

[0072] The display panel 200 has a display function, so the display panel 200 usually needs to be set on the side of the heating plate 100. When the fan 500 cannot blow the airflow directly to the display panel 200, the first air duct 610 can be set to have an angled structure. Among them, the first sub-air duct 611 and the second sub-air duct 612 are connected, and the first sub-air duct 611 is connected to the exhaust port 510. At least a part of the display panel 200 is located on the path of the second sub-air duct 612. In order to increase the contact time between the airflow and the display panel 200, the second sub-air duct 612 is set to extend in the same direction as the display panel 200. During the process of the airflow flowing in the second sub-air duct 612, the airflow in the second sub-air duct 612 can continue to contact the display panel 200, which is conducive to improving the heat dissipation effect of the display panel 200.

[0073] In some embodiments, optionally, the first air duct 610 also includes: a third sub-air duct 613, a first end of the third sub-air duct 613 is connected to the second end of the second sub-air duct 612, the air outlet 430 is connected to the third sub-air duct 613, and an angle is set between the third sub-air duct 613 and the second sub-air duct 612.

[0074] In the case that the air outlet 510 and the display panel 200 are misaligned, the air outlet 510 and the second sub-duct 612 may be connected via the third sub-duct 613 .

[0075] After the airflow dissipates heat from the display panel 200, the temperature of the airflow rises, connecting the air outlet 430 with the third sub-air duct 613. An angle is set between the third sub-air duct 613 and the second sub-air duct 612, so that the air outlet 430 can be moved away from the display panel 200 to avoid the airflow discharged from the shell 400 from contacting the display panel 200, thereby preventing the high-temperature airflow from affecting the stable operation of the display panel 200.

[0076] Combination Figure 1 and Figure 2 As shown, in some embodiments, optionally, the cooking device further includes: an air guide bracket 600 , the air guide bracket 600 is connected to the heating plate 100 , and a first air duct 610 and a second air duct 620 are provided on the air guide bracket 600 .

[0077] The air guide bracket 600 is machined with a first air duct 610 and a second air duct 620. When the air guide bracket 600 is installed on the heating plate 100, the air duct structure on the air guide bracket 600 faces the exhaust port 510 and the air outlet 430. Therefore, there is no need to set an air duct structure on the heating plate 100 and the shell 400, and there is no need to make major changes to the structures of the heating plate 100 and the shell 400, which is beneficial to improving the processing convenience of the air duct structure.

[0078] Combination Figure 1 and Figure 2 As shown, in some embodiments, optionally, a mounting cavity 630 is provided on the air guide bracket 600 , the fan 500 is located in the mounting cavity 630 , and a portion of the air guide bracket 600 is distributed along the circumference of the air outlet 510 .

[0079] An installation cavity 630 is formed on the air guide bracket 600, and the fan 500 is installed in the installation cavity 630. The installation cavity 630 protects the fan 500. In this case, the air guide bracket 600 can separate the fan 500 from other components to avoid mutual interference between different components, and also prevent the fan 500 from being bumped by other components, thereby reducing the damage rate of the fan 500.

[0080] A portion of the air guide bracket 600 is distributed along the circumference of the exhaust port 510, that is, in this case, the air guide bracket 600 can prevent the airflow in the first air duct 610 and the second air duct 620 from flowing into the installation cavity 630, ensuring that the airflow can stably flow into the first air duct 610 and the second air duct 620, avoiding the airflow from circulating in the installation cavity 630, which is beneficial to improving the heat dissipation effect of the control board 300 and the display panel 200.

[0081] Combination Figure 1 and Figure 2 As shown, in some embodiments, optionally, the partition 700 is integrally provided with the air guide bracket 600 .

[0082] When processing the air guide bracket 600, the partition 700 is directly processed on the air guide bracket 600, so that the partition 700 and the air guide bracket 600 are an integrated structure. After the air guide bracket 600 is installed, the partition 700 is located at the position of the exhaust port 510. Therefore, there is no need to install the partition 700 separately, which is beneficial to improving the assembly convenience of the cooking equipment and reducing the number of parts inside the cooking equipment, which is beneficial to improving the processing convenience and reducing the processing cost.

[0083] Of course, in other embodiments, the partition 700 and the air guide bracket 600 are two independent components, and the partition 700 can also be fixed to the air guide bracket 600 by welding or bonding.

[0084] Combination Figure 1 and Figure 2 As shown, in some embodiments, optionally, the control panel 300 is located in the opening direction of the air outlet 510 .

[0085] The control board 300 is arranged in the opening direction of the air outlet 510 so that the airflow blown out by the fan 500 can be directly blown toward the control board 300 .

[0086] Specifically, the heat generated by the control panel 300 is usually greater than the heat generated by the display panel 200. By setting the control panel 300 in the opening direction of the exhaust port 510, the airflow does not need to turn and blows directly to the control panel 300, which is beneficial to improving the heat dissipation efficiency of the control panel 300 and ensuring the operating stability of the control panel 300.

[0087] In some embodiments, optionally, the first side of the control panel 300 faces the exhaust port 510 , the second side of the control panel 300 is a side adjacent to the first side of the control panel 300 , and the display panel 200 is located on the second side of the control panel 300 .

[0088] The first side of the control panel 300 and the second side of the control panel 300 are two adjacent sides of the control panel 300. The first side of the control panel 300 faces the exhaust port 510, and the display panel 200 is located on the second side of the control panel 300. Therefore, the display panel 200 is adjacent to the exhaust port 510. The airflow discharged from the exhaust port 510 passes through the display panel 200 after flowing a short distance. At this time, the airflow maintains a high flow rate, which is beneficial to improve the heat dissipation effect of the display panel 200.

[0089] In some embodiments, optionally, at least a portion of the first air duct 610 is located on one side of the control panel 300 .

[0090] On the one hand, the wind discharged from the exhaust port 510 can be blown directly to the control panel 300. On the other hand, the heat is further dissipated through the auxiliary effect of the first air duct 610, which is beneficial to improve the heat dissipation effect of the control panel 300. At the same time, the wind from the first air duct 610 can dissipate heat for the display panel 200. The display panel 200 and the fan 500 are arranged at a distance to reduce the influence of the motor vibration on the display panel 200.

[0091] Combination Figure 1 and Figure 2 As shown, in some embodiments, optionally, the distance between the air outlet 510 and the control panel 300 is smaller than the distance between the air outlet 510 and the display panel 200 .

[0092] The distance between the exhaust port 510 and the control panel 300 is small, and the distance between the exhaust port 510 and the control panel 300 is large. Therefore, the airflow can quickly reach the control panel 300. The heat generated by the control panel 300 is usually greater than the heat generated by the display panel 200. By reducing the distance between the exhaust port 510 and the control panel 300, it is beneficial to improve the heat dissipation efficiency of the control panel 300 and ensure the operating stability of the control panel 300.

[0093] Combination Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, optionally, an air inlet 440 is provided on the shell 400, and the air inlet 420 is provided on the air inlet 440, the area of ​​the air inlet 440 is S1, and the area of ​​the positive projection of the fan 500 on the shell 400 is S2, 0.8×S1≤S2≤1.2×S1.

[0094] The area where the air inlet 440 is located is provided with an air inlet 420 , and the area of ​​the air inlet 440 is relatively close to the projected area of ​​the fan 500 , ensuring that the fan 500 can smoothly inhale external air, which is beneficial to improving the driving effect of the fan 500 on the airflow.

[0095] In some embodiments, optionally, the display panel 200 and the control panel 300 are both connected to the heating plate 100 .

[0096] The display panel 200 and the control panel 300 are disposed on the heating plate 100 . When the housing 400 is disassembled, the display panel 200 and the control panel 300 will not interfere with the disassembly process of the housing 400 , thereby improving the convenience of disassembly of the housing 400 .

[0097] The cooking device in this embodiment is a shell-enclosed structure, where the shell 400 covers the entire control panel 300 area. The heat of the heating plate 100 can be directly transferred to the display panel 200 area. Therefore, a fan 500 is required to dissipate heat internally in this structure.

[0098] As for the air duct design of the fan 500, firstly, the air outlet of the fan 500 is divided into two paths (a first air duct 610 and a second air duct 620), one air outlet portion (the second air outlet 432) blows directly toward the control panel 300, and the other air outlet portion (the first air outlet 431) is guided to the back of the display panel 200 through the structural design of the air guide bracket 600. Through the branch design, the heat radiation from the heating disk 100 to the control panel 300 and the display panel 200 is reduced, wherein the second air duct 620 is a strong wind area, and the first air duct 610 is a weak wind area.

[0099] In order to form air circulation inside and outside, an air inlet 420 of similar size to the fan 500 is designed on the shell 400 of the machine. For the air outlet of the air duct, the second air duct 620 has a short flow channel and strong wind force, and it is necessary to directly open a hole at the control panel 300 to prevent hot air from circulating inside and complete the air change as soon as possible. Therefore, the shell 400 at the bottom of the control panel 300 is designed to be a slope-shaped stepped air outlet. The first air duct 610 is long and weak, and the first air outlet 431 is designed at the end of the air duct. At the same time, the air outlets of the two air ducts need to be separated by a certain distance to avoid interference between the two air outlets.

[0100] The airflow in the first air duct 610 will flow through the display panel 200, and the airflow will take away the heat on the surface of the display panel 200. The airflow in the second air duct 620 will flow through the control panel 300, and the airflow will take away the heat on the surface of the control panel 300, thereby achieving the heat dissipation function for the display panel 200 and the control panel 300. Through the cooperation of the fan 500, the first air duct 610 and the second air duct 620, the heat dissipation of the control panel 300 and the display panel 200 can be achieved during the operation of the cooking device, so as to avoid the occurrence of over-high temperature of the control panel 300 and the display panel 200, ensure the operation stability of the control panel 300 and the display panel 200, reduce the damage rate of the control panel 300 and the display panel 200, and avoid the failure of the function of the control panel 300 and the display panel 200.

[0101] The design of the fan duct and housing air outlet can greatly reduce the temperature rise of internal electronic components and improve product reliability and component performance.

[0102] In one possible application, the cooking device in this embodiment is a multifunctional electric hot pot. Of course, in other embodiments, the heat dissipation structure can also be used for other desktop electronic cooking appliances. By adding a fan design, the temperature rise of the internal display panel and control panel of the electronic multifunctional pot is reduced. In addition, the optimized design of the air duct reduces the temperature rise by about 50 degrees Celsius, which greatly improves the reliability and safety of the product, enables the product to cope with various harsh working environments, and improves the quality of the product.
