Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a cooking device. Background Art

[0002] When cooking equipment such as induction cookers are working, the internal coil disks, IGBTs and other electronic components will generate heat. In order to avoid overheating and damage of the internal components, timely heat dissipation is required.

[0003] When the existing cooking equipment is working, the axial flow fan sucks air to the panel, and then uses the wind pressure to blow air to the coil disk and the heat sink of the IGBT to dissipate heat for the heating elements inside the cooking equipment. Since the axial flow fan sucks air from the bottom and blows it to the top plane to form wind pressure, the amount of air blown into the cooking equipment by the wind pressure is relatively small, resulting in poor heat dissipation effect of the cooking equipment, and it is difficult to achieve high-power heating.

[0004] Therefore, there is an urgent need to solve the technical problem of poor heat dissipation effect of cooking equipment. Utility Model Content

[0005] The utility model provides a cooking device, which is used to solve the technical problem of poor heat dissipation effect of the cooking device.

[0006] In order to achieve the above object, the utility model provides a cooking device, comprising:

[0007] A housing, wherein the housing has a containing cavity, wherein the containing cavity has a heating area and an air inlet area which are arranged at intervals from each other, wherein the heating area is used to arrange a heating element, and wherein a fan is arranged in the air inlet area;

[0008] An air guide member is arranged in the accommodating cavity, and the air guide member includes a first guide plate. The first guide plate has a smooth transition between a side of the air inlet area away from the heating area and an upper side of the air inlet area, so as to guide the airflow introduced by the fan to the heating area.

[0009] The utility model provides a cooking device, which is provided with an air guide member, wherein the air guide member includes a first guide plate, and the first guide plate is smoothly transitioned between a side of an air inlet area away from a heating area and an upper side of the air inlet area, so that the air guide member can guide the airflow to increase the wall attachment effect, change the movement trajectory of the airflow, guide more airflow to the heating element, improve the heat dissipation effect of the cooking device, and help the cooking device to achieve high-power heating.

[0010] In a possible implementation, the side of the first guide plate facing the fan is a curved surface or an inclined surface, which is conducive to better guiding the airflow. The airflow on the side of the air inlet area away from the heating area moves along the inner wall surface of the first guide plate to the upper side of the air inlet area and finally flows toward the heating area, dissipating heat for the heating element arranged in the heating area, effectively preventing the temperature of the heating element from being too high, and helping to achieve high-power heating.

[0011] In a possible implementation, the air guide member further includes a second guide plate, the second guide plate is connected to the first guide plate, and the second guide plate is located on the upper side of at least part of the air inlet area, and an opening facing the heating area is formed between the second guide plate and the inner bottom wall of the housing. The second guide plate is conducive to guiding the airflow toward the heating element in the heating area, so that more airflow enters the heating area.

[0012] In a possible implementation, the fan is located between the air guide and the inner bottom wall of the housing, and a fixing frame is provided on the side of the fan facing away from the inner bottom wall of the housing, and a guide channel for airflow is formed between the fixing frame and the second guide plate. The guide channel has a good guiding effect on the airflow, which helps the airflow to flow out through the guide channel and flow to the heating element in the heating area.

[0013] In a possible implementation, the air guide also includes a side baffle, which is connected to the first guide plate and blocks an edge of the air inlet area on one side facing away from the heating area. The side baffle can prevent the airflow introduced by the fan from dissipating from the side of the fan facing away from the heating area, so that more airflow and stronger wind force are blown into the heating area, thereby improving the heat dissipation effect on the heating element and effectively solving the problem of overheating of the heating element.

[0014] In a possible implementation, the cooking device further includes a panel, the panel covers the top of the housing, and the air guide is connected to the panel, the inner bottom wall of the housing, and at least one of the fan, so as to facilitate the fixed installation of the air guide.

[0015] In a possible implementation, the air guide also includes a connecting plate, the connecting plate is connected to an end of the second guide plate away from the first guide plate, and the air guide is connected to the fan via the connecting plate. The connecting plate and the fan are relatively fixed in position, so that the air guide better guides the airflow introduced by the fan, thereby making full use of the airflow introduced by the fan and improving the heat dissipation effect.

[0016] In a possible implementation, the inner bottom wall of the shell is provided with wind shielding ribs, the wind shielding ribs surround the edge of the air inlet area, and the air guide abuts against one end of the wind shielding ribs away from the shell. The wind shielding ribs support the air guide to improve the stability of the air guide fixing, reduce the deformation and shaking of the air guide, and thus ensure the stable air guiding effect of the air guide.

[0017] In a possible implementation, the air guide further includes a boss portion, the boss portion is connected between the first guide plate and the side baffle, and the boss portion abuts against an end of the wind shielding rib away from the housing. By providing the boss portion, it is easy to fix the air guide, and it is easy to rely on the wind shielding rib to provide support for the air guide.

[0018] In a possible implementation, the fan is an axial flow fan, which can effectively move a large amount of air and discharge the air in the same direction as the fan shaft, so that more airflow enters the guide channel; and / or,

[0019] It also includes a heating element, which includes a heating plate and a control panel.

[0020] In a possible implementation, the bottom wall of the housing is provided with an air inlet hole, the air inlet hole is located in the air inlet area, and is connected to the outside of the housing. External air enters the air inlet area through the air inlet hole, and then moves in the same direction as the fan shaft, thereby being gathered into the guide channel, so that more airflow can be sent to the heating area to dissipate heat for the heating element. Since the air volume blowing to the heating element is increased, the heat dissipation effect is improved.

[0021] The utility model provides a cooking device, which can change the flow direction of wind inside the cooking device by arranging an air guide, so that the heat dissipation effect inside the cooking device is better, the temperature rise of the IGBT module and the heating plate is low, and long-term high-power heating can be achieved to improve the cooking effect.

[0068] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0069] When the cooking equipment is working, the internal heating plate and IGBT module are prone to generate high temperatures. If the heat is not dissipated in time, it will affect the service life of the cooking equipment and even affect the safety of use.

[0070] Usually, a heat sink is stacked on the side of the IGBT module, and then a fan is used to accelerate the flow of air to dissipate heat for the IGBT module. However, in current cooking equipment, the wind introduced by the axial flow fan is mainly blown to the heating plate and the IGBT module and other heating parts by wind pressure. The air volume is relatively small, and the wind force transmitted to the heating parts will be weakened, resulting in poor overall heat dissipation effect.

[0071] In view of this, the cooking device provided by the utility model is provided with an air guide member, which includes a first guide plate. The first guide plate has a smooth transition between the side of the air inlet area away from the heating area and the upper side of the air inlet area, so that the air guide member guides the airflow to increase the wall attachment effect, change the movement trajectory of the airflow, and guide more airflow to the heating element arranged in the heating area, thereby improving the heat dissipation effect of the cooking equipment and helping the cooking equipment to achieve high-power heating.

[0072] The cooking device provided by the embodiment of the utility model is described below with reference to the accompanying drawings.

[0073] refer to Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a cooking device, including: a housing 10 and an air guide 20, the housing 10 has a receiving cavity 11, the receiving cavity 11 has a heating area 111 and an air inlet area 112 arranged at intervals from each other, the heating area 111 is used to set a heating element, and the air inlet area 112 is provided with a fan 30;

[0074] refer to Figure 4As shown, the air guide member 20 is arranged in the accommodating cavity 11, and the air guide member 20 includes a first guide plate 21. The first guide plate 21 has a smooth transition between the side of the air inlet area 112 away from the heating area 111 and the upper side of the air inlet area 112, so as to guide the airflow introduced by the fan 30 to the heating area 111.

[0075] The utility model provides a cooking device, which is provided with an air guide 20, wherein the air guide 20 includes a first guide plate 21, and the first guide plate 21 is smoothly transitioned between the side of the air inlet area 112 away from the heating area 111 and the upper side of the air inlet area 112, so that the air guide 20 can guide the airflow to increase the wall attachment effect, change the movement trajectory of the airflow, guide more airflow to the heating element, improve the heat dissipation effect of the cooking device, and help the cooking device to achieve high-power heating.

[0076] Under the action of the air guide 20, the flow direction of the air flow will change and it will flow along the surface of the air guide 20. Due to the friction and viscosity between the air flow and the surface of the air guide 20, the flow velocity of the air flow near the surface of the air guide 20 slows down, while the flow velocity of the fluid farther away is faster. This speed difference causes the air flow to be pulled toward the surface of the air guide 20 under the action of the viscosity, thereby changing the movement trajectory of the air flow, which helps to guide the air flow to the heating element set in the heating area 111, thereby improving the heat dissipation effect of the cooking equipment.

[0077] refer to Figure 5 , Figure 6 and Figure 7 As shown, the first guide plate 21 has a smooth transition between the side of the air inlet area 112 away from the heating zone 111 and the upper side of the air inlet area 112, compared with a sharp-angle transition of the first guide plate 21 between the side of the air inlet area 112 away from the heating zone 111 and the upper side of the air inlet area 112, such as a right-angle transition, the resistance of the airflow can be reduced, and the attenuation of the airflow speed can be reduced, thereby helping to guide the airflow to the heating element and improving the heat dissipation effect of the cooking equipment.

[0078] The air guide member 20 is located in the air inlet area 112 . A fan installation cavity is formed between the air guide member 20 and the inner bottom wall of the housing 10 . The fan 30 is disposed in the fan installation cavity.

[0079] In a possible implementation, the side of the first guide plate 21 facing the fan 30 is a curved surface or an inclined surface, which is conducive to better guiding the airflow. The airflow located on the side of the air inlet area 112 away from the heating area 111 moves along the inner wall surface of the first guide plate 21 to the upper side of the air inlet area 112, and finally flows toward the heating area 111, dissipating heat for the heating element arranged in the heating area 111, which can effectively prevent the temperature of the heating element from being too high, and help to achieve high-power heating.

[0080] It is easy to understand that the longitudinal section of the first guide plate 21 is in an arc shape or an inclined surface shape.

[0081] In one possible implementation, reference Figure 6 and Figure 7 As shown, the air guide member 20 further includes a second guide plate 22, which is connected to the first guide plate 21, and is located on the upper side of at least part of the air inlet area 112, and an opening toward the heating area 111 is formed between the second guide plate 22 and the inner bottom wall of the housing 10. The second guide plate 22 is conducive to guiding the airflow toward the heating element in the heating area 111, so that more airflow enters the heating area 111.

[0082] refer to Figure 6 The direction indicated by the dashed arrow is the flow direction of the airflow. The airflow introduced by the fan 30 moves along the inner wall surface of the first guide plate 21 to the upper side of the air inlet area 112, then flows out through the opening and blows toward the heating area 111 to dissipate heat for the heating element arranged in the heating area 111.

[0083] In one possible implementation, reference Figure 7 and Figure 8 As shown, the second guide plate 22 may be in the shape of a straight plate, or may be in the shape of a plate inclined toward the inner bottom wall of the housing 10 .

[0084] In a possible implementation, the fan 30 is located between the air guide 20 and the inner bottom wall of the housing 10, and the side of the fan 30 facing away from the inner bottom wall of the housing 10 has a fixing frame 31. Fig. 9 , Fig.10 and Fig.11 As shown, a guide channel 60 for airflow is formed between the fixing frame 31 and the second guide plate 22. The guide channel 60 can guide the airflow well, so that the airflow flows to the heating element in the heating area 111 through the guide channel 60. The fixing frame 31 is used to fix the fan 30 in the accommodating cavity 11.

[0085] In one possible implementation, reference Fig.12 As shown, the fixing frame 31 is in a strip shape, the center position of the fixing frame 31 is connected to the fan 30, the two ends of the fixing frame 31 extend along the radial direction of the fan 30, and the two ends of the fixing frame 31 are provided with fixing holes 311. The inner bottom wall of the shell 10 is provided with a fixing column 14, and the two ends of the fixing frame 31 abut against the fixing column 14. Fasteners such as screws are inserted into the fixing holes 311 and the fixing column 14 to achieve connection between the fixing frame 31 and the fixing column 14, so that the fan 30 is stably fixed in the accommodating cavity 11.

[0086] In one possible implementation, reference Fig.12 and Fig.13 As shown, the air guide 20 further includes a side baffle 23 , which is connected to the first guide plate 21 , and blocks an edge of the air inlet area 112 that is away from the heating area 111 .

[0087] The side baffle 23 can prevent the airflow introduced by the fan 30 from dissipating from the side of the fan 30 facing away from the heating area 111, so that the airflow blowing into the heating area 111 is larger and the wind force is stronger, thereby improving the heat dissipation effect on the heating element and effectively solving the problem of overheating of the heating element.

[0088] In one possible implementation, the air inlet area 112 is a circular area, and the side baffle 23 may be arranged along the edge of the air inlet area 112. There may be a gap between the side baffle 23 and the inner bottom wall of the shell 10. Of course, the side baffle 23 may also be directly in contact with the inner bottom wall of the shell 10.

[0089] In one possible implementation, reference Figure 8 As shown, the first guide plate 21, the second guide plate 22 and the side baffle plate 23 are an integral structure connected in one piece, which is easy to produce.

[0090] In one possible implementation, reference Figure 2 and Figure 3 As shown, the cooking device further comprises a panel 70, the panel 70 covers the top of the housing 10, and the air guide 20 is connected to at least one of the panel 70, the inner bottom wall of the housing 10, and the fan 30. It is convenient to realize the fixed installation of the air guide 20.

[0091] In a possible implementation, the panel 70 includes but is not limited to a heat-resistant ceramic or microcrystalline glass panel.

[0092] In one possible implementation, reference Figure 7 and Figure 8 As shown, the air guide 20 further includes a connecting plate 24, which is connected to one end of the second guide plate 22 away from the first guide plate 21, and the air guide 20 is connected to the fan 30 via the connecting plate 24. The positions of the connecting plate 24 and the fan 30 are kept relatively fixed, so that the air guide 20 can better guide the airflow introduced by the fan 30, thereby making full use of the airflow introduced by the fan 30 and improving the heat dissipation effect.

[0093] In a possible implementation, a connection hole 241 is provided in the connection plate 24, and a fastener such as a screw or a bolt is inserted into the connection hole 241 and the fixing frame 31 to achieve the connection between the air guide 20 and the fan 30. Of course, the connection plate 24 can also be connected to the fixing frame 31 through a buckle, for example, a buckle is provided on the side of the connection plate 24 facing the fixing frame 31, and a slot matching the buckle is provided in the fixing frame 31, and the buckle is inserted into the slot to achieve the connection between the air guide 20 and the fan 30, so that the position of the air guide 20 relative to the fan 30 is fixed.

[0094] The connecting plate 24 may be extended from the second guide plate 22 along the radial direction of the air guide member 20 , or may be extended from the second guide plate 22 along the direction toward the heating area 111 , which is not specifically limited here.

[0095] In order to improve the stability of the air guide 20, the number of the connecting plates 24 can be 2 or 3, and the 2 or 3 connecting plates 24 are spaced apart from each other.

[0096] In one possible implementation, a positioning column is provided on the connecting plate 24, and a positioning hole is opened in the fixing frame 31, and the position of the positioning hole corresponds to the position of the positioning column. Thus, by inserting the positioning column into the positioning hole, the positioning effect of the air guide member 20 relative to the fan 30 is achieved, which is beneficial to improving the air guiding effect of the air guide member 20.

[0097] The second guide plate 22 may have a gap with the panel 70 or may be in close contact with the panel 70 .

[0098] In one possible implementation, reference Figure 3 and Figure 4 As shown, the second guide plate 22 may be attached to the panel 70 , and the second guide plate 22 or the connecting plate 24 may be attached to the lower surface of the panel 70 by an adhesive, such as a colloid, to achieve the fixation of the air guide 20 .

[0099] In a possible implementation, the bottom of the first guide plate 21 may be connected to the inner bottom wall of the housing 10 , for example, by screws or adhesive bonding, so as to fix the air guide member 20 .

[0100] In one possible implementation, reference Fig.10 and Fig.11 As shown, the inner bottom wall of the housing 10 is provided with wind shielding ribs 13, which surround the edge of the air inlet area 112, and the wind guide 20 abuts against the end of the wind shielding ribs 13 away from the housing 10. The height of the wind shielding ribs 13 is not specifically limited here and can be flexibly selected according to the use requirements.

[0101] refer to Fig.11 and Fig.12As shown, the wind shield rib 13 can be an integral structure integrally connected to the inner bottom wall of the shell 10. By abutting the air guide member 20 against the end of the wind shield rib 13 away from the shell 10, the wind shield rib 13 can support the air guide member 20, thereby improving the stability of the fixation of the air guide member 20 and reducing the deformation and shaking of the air guide member 20, thereby ensuring the stable air guiding effect of the air guide member 20.

[0102] refer to Fig.11 The direction indicated by the dotted arrow is the flow direction of the airflow. The airflow introduced by the partial fan 30 moves upward along the inner wall surface of the wind shield rib 13 to the air guide member 20, and under the guidance of the air guide member 20, moves toward the upper side of the air inlet area 112 along the inner wall of the air guide member 20, and then flows to the heating area 111 through the guide channel 60, so as to dissipate heat for the heating element arranged in the heating area 111, thereby increasing the air volume blown toward the heating area 111.

[0103] In a possible implementation, the air guide 20 further includes a boss portion 25, the boss portion 25 is connected between the first guide plate 21 and the side baffle plate 23, and the boss portion 25 abuts against the end of the wind shielding rib 13 away from the housing 10. By providing the boss portion 25, it is convenient to fix the air guide 20, and the boss portion 25 forms a sudden change in the inner diameter between the connection positions of the first guide plate 21 and the side baffle plate 23, so that the wind shielding rib 13 can provide support for the air guide 20.

[0104] In one possible implementation, the boss portion 25 may be protruding toward the inner side of the first guide plate 21, so that the inner diameter of the side baffle plate 23 is smaller than the inner diameter of one end of the first guide plate 21 connected to the boss portion 25, thereby facilitating extending the side baffle plate 23 to the inner side of the wind shield rib 13 so that the boss portion 25 abuts against the end of the wind shield rib 13 away from the shell 10.

[0105] In another possible implementation, reference Fig.11 , Fig.14 and Fig.15 As shown, the boss portion 25 can also protrude toward the outer side of the first guide plate 21, so that the inner diameter of the side baffle plate 23 is larger than the inner diameter of one end of the first guide plate 21 connected to the boss portion 25, thereby facilitating the extension of the side baffle plate 23 to the outer side of the wind shield rib 13, so that the boss portion 25 abuts against the end of the wind shield rib 13 away from the shell 10.

[0106] In one possible implementation, reference Figure 2 and Figure 3As shown, the bottom wall of the housing 10 is provided with an air inlet hole 12, which is located in the air inlet area 112 and communicated with the outside of the housing 10. External air enters the air inlet area 112 through the air inlet hole 12, and then moves in the same direction as the fan shaft, thereby converging into the guide channel 60, so that more airflow can be sent to the heating area 111 to dissipate heat for the heating element. Since the air volume blowing to the heating element is increased, the heat dissipation effect is improved.

[0107] The air inlet holes 12 include but are not limited to circular holes, elliptical holes, polygonal holes, waist-shaped holes, etc. The number of air inlet holes 12 can be multiple and arranged at intervals, which not only allows airflow to pass through, but also prevents insects from entering the outside world with a smaller aperture, thereby avoiding affecting the normal operation of the cooking device.

[0108] In one possible implementation, reference Fig.12 , Fig.13 and Fig.14 As shown, both ends of the side baffle 23 have notches 26 , and the notches 26 are used to avoid the fixing frame 31 , so that both ends of the fixing frame 31 can extend to the outside of the air guide 20 through the notches 26 .

[0109] In a possible implementation, the fan 30 is an axial flow fan. An axial flow fan has the advantages of low noise and can save space. An axial flow fan can effectively move a large amount of air, moving the air in the same direction as the fan shaft, so that more air flows into the guide channel 60.

[0110] refer to Figure 4 and Fig.11 As shown, under the action of the axial flow fan, air enters the air inlet area 112 through the air inlet hole 12 provided on the bottom wall of the shell 10, and is transported upward along the axial direction of the fan 30. After the airflow encounters the air guide member 20, it can flow better to the heating area 111 under the guidance of the air guide member 20, thereby improving the heat dissipation effect on the heating element.

[0111] In one possible implementation, reference Figure 8 As shown, the cooking device further includes a heating element, which includes a heating plate 40 and a control panel 50 .

[0112] The control board 50 is a printed circuit board (PCB), and an insulated gate bipolar transistor (IGBT) module is installed on the control board 50. Since the IGBT module 51 is prone to overheating and damage when the cooking equipment is in use, the present application guides cold air to the control board 50, which helps to dissipate heat and cool the IGBT module 51, thereby ensuring the normal operation of the IGBT module 51.

[0113] In this example, the housing 10 includes a bottom housing and an upper housing, the upper housing can be buckled on the bottom housing, the bottom housing and the upper housing together form a receiving cavity 11, and the panel 70 can be covered on the top of the upper housing. The inner bottom wall of the housing 10 is the inner bottom wall of the bottom housing.

[0114] In other possible implementations, the shell 10 further includes a bottom shell, a middle shell and an upper shell, and the middle shell is connected between the bottom shell and the upper shell.

[0115] refer to Figure 5 and Figure 8 As shown, a plurality of legs 15 are connected to the bottom of the shell 10, for example, four legs 15, which are respectively connected to the corners of the shell 10 to improve the stability of the placement of the cooking device. A plurality of heat dissipation holes 16 are opened on the side wall of the shell 10, and the airflow that takes away the heat of the heating element flows out to the outside of the cooking device through the heat dissipation holes 16 to achieve heat dissipation for the cooking device.

[0116] The cooking device provided by the utility model includes but is not limited to an induction cooker, and may also be other electromagnetic heating devices and the like.
