Referring to fig. 1 to 2, a microwave cooking apparatus 100 according to an embodiment of the present invention includes a magnetron 11, a wind scooper 12, and a fan 14. The magnetron 11 is provided with an air inlet 112, a heat dissipation channel 114 and an air outlet 116 which are communicated. The air scoop 12 is positioned between the air inlet 112 and the air outlet side 142 of the fan 14 (see fig. 5). The wind scooper 12 includes a first wind deflector 122 and a second wind deflector 124, and the first wind deflector 122 is vertically connected to the second wind deflector 124. The second air deflectors 124 are disposed along the length direction a-a of the heat dissipation channel 114.
In the microwave cooking apparatus 100, the first air deflector 122 is vertically connected to the second air deflector 124, and the second air deflector 124 is disposed along the length direction a-a of the heat dissipation channel 114. Therefore, the stroke of the air beam 200 of the fan 14 entering the magnetron 11 can be shortened, the air volume divergence is reduced, the loss of the wind speed is reduced, the direction of the air beam 200 can be adjusted to be the same as the direction of the heat dissipation channel 114, the wind resistance is reduced, the effective contact area is increased, and the heat dissipation effect is further improved.
In the related art, in order to ensure the heat dissipation capacity of the magnetron, the cross section area of the air guide cover is increased mostly, so that the area of the air guide cover is large, the shape of the air guide cover is fixed, the air guide cover is difficult to adapt to the installation of the magnetron, and the air guide function of the air guide cover is only effective in the vertical direction, and the incoming air in other directions cannot be guided. Therefore, the complexity of the air guide cover arranged on the magnetron and the stroke of the air entering the magnetron are increased, the heat dissipation effect of the magnetron is reduced, and the use effect of the microwave cooking equipment is greatly influenced. Therefore, in order to ensure the effective and timely cooling of the magnetron, the structure of the wind scooper needs to be improved.
Specifically, referring to fig. 1 and 5, the wind scooper 12 is located between the magnetron 11 and the fan 14, when the microwave cooking apparatus 100 is in operation, the fan 14 rotates to make the wind beam 200 outside the microwave cooking apparatus 100 enter the wind scooper 12, and after the wind beam 200 outside the microwave cooking apparatus touches the wall surface of the wind scooper 12, the wind beam 200 can flow along the wall surface of the wind scooper 12, since the first wind deflector 122 and the second wind deflector 124 are vertically connected, the direction of the wind beam 200 can be changed by the first wind deflector 122 and the second wind deflector 124, so that the direction of the wind beam 200 can be adjusted to be the same as the length direction of the heat dissipation channel 114 of the magnetron 11, i.e. the functions of collecting and rectifying are performed, thus, the divergence of the wind beam 200 can be greatly reduced, the stroke of the fan 14 entering the magnetron 11 can be shortened, the wind beam 200 can be guided to enter the heat dissipation channel 114 along the wind scooper 12, thereby effectively cooling the magnetron 11, so that the microwave cooking apparatus 100 can be stably used.
The first air guiding plate 122 is vertically connected to the second air guiding plate 124, which may mean that an included angle formed by the first air guiding plate 122 and the second air guiding plate 124 is 90 degrees, or that a difference between the included angle formed by the first air guiding plate 122 and the second air guiding plate 124 and 90 degrees is within a desired range.
In the illustrated embodiment, the first air deflection plate 122 and the second air deflection plate 124 are integrally connected in an L-shape. It is understood that in other embodiments, the first air deflection plate 122 and the second air deflection plate 124 may be integrally connected in a T-shape.
The heat dissipation channel 114 may be formed by heat dissipation fins of a heat sink within the magnetron 11.
In some embodiments, the length L1 of the second air deflection panel 124 is greater than the width L2 of the intake vent 112. Thus, the wind of the fan 14 can be guided into the heat dissipation channel 114, and the heat dissipation effect is further improved.
Specifically, the length L1 of the second air guiding plate 124 is greater than the width L2 of the air inlet 112, so that the second air guiding plate 124 can span the entire air inlet 112, and both the air flow 200 on the width of the air inlet 112 are rectified and collected, thereby increasing the air inlet amount and further increasing the heat dissipation effect.
More specifically, referring to fig. 1 and 2, the second air deflector 124 may be installed at the air inlet 112, the air inlet 112 is partitioned into a first air inlet 1122 and a second air inlet 1124 by the second air deflector 124, and the area of the second air inlet 1124 is larger than that of the first air inlet 1122. In the present embodiment, the position of the heat dissipation channel 114 corresponds to the position of the second air inlet 1124, so that the air beam 200 generated by the fan 14 is basically guided to the second air inlet 1124 by the second air guiding plate 124, and then enters the heat dissipation channel 114, thereby further improving the heat dissipation effect of the magnetron 11, so that the microwave cooking apparatus 100 can be effectively cooled in time, and the phenomenon of poor performance due to over-high temperature is avoided.
In some embodiments, the wind scooper 12 is provided with at least one first wind deflector 122, and at least one second wind deflector 124.
Thus, by adjusting the number of the first wind deflector 122 and the second wind deflector 124 of the wind scooper 12, the design of the wind scooper 12 is more flexible and varied to meet different requirements.
Specifically, at least one may include one or more, and a plurality may mean two or more. In the present embodiment, referring to fig. 2, the wind scooper 12 includes a first wind deflector 122 and a second wind deflector 124, and the wind scooper 12 is formed by vertically connecting the first wind deflector 122 and the second wind deflector 124, and has a simple structure, easy implementation and low cost.
In other embodiments, the wind scooper 12 may be provided with one first wind deflector 122 and a plurality of second wind deflectors 124. In such an embodiment, two adjacent second wind deflectors 124 are spaced to form a longitudinal wind guiding channel, and the longitudinal wind guiding channel has a length direction parallel to the length direction of the heat dissipation channel 114, so that the wind bundle 200 can be further rectified, and the heat dissipation effect is improved.
In other embodiments, the wind scooper 12 may be provided with a plurality of first wind deflectors 122 and one second wind deflector 124. In such an embodiment, two adjacent first wind deflectors 122 are spaced to form a transverse wind guiding channel, and the length direction of the transverse wind guiding channel is perpendicular to the length direction of the heat dissipation channel 114, so that the wind bundle 200 can be further rectified, and the heat dissipation effect is improved.
In still other embodiments, the wind scooper 12 may further include a plurality of first wind deflectors 122 and a plurality of second wind deflectors 124, such that the plurality of first wind deflectors 122 and the plurality of second wind deflectors 124 are cross-connected to form a grid-shaped wind guiding channel, which can further rectify the wind bundle 200, and improve the heat dissipation effect.
In some embodiments, the first air deflection plate 122 is a straight plate or a curved plate, and the second air deflection plate 124 is a straight plate or a curved plate.
In this way, the different shapes of the first and second air deflectors 122 and 124 can match the magnetrons 11 with different shapes, so that the air guiding cover 12 is diversified.
Specifically, referring to fig. 2, in the illustrated embodiment, the first air guiding plate 122 and the second air guiding plate 124 are straight plates, and each of the shapes is a flattened rectangular parallelepiped. In other embodiments, the shapes of the first wind deflector 122 and the second wind deflector 124 may be the same or different, and the specific shape of the straight plate may be other shapes, which is not limited herein.
In the present embodiment, the length L1 of the second air guiding plate 124 may be [75, 135] mm, and preferably, in the present embodiment, the length L1 may be selected from the range of [60, 120] mm. The width L3 of the first air guiding plate 122 is the same as the width of the second air guiding plate 124, the width L3 may be [12, 30] mm, and preferably, in the present embodiment, the width L3 may be selected in the range of [18, 24] mm. The length L4 of the first air guiding plate 122 may be [20, 70] mm, and preferably, in the present embodiment, the length L4 may be selected from the range of [30, 60] mm. And is not particularly limited herein.
In other embodiments, the first air deflector 122 and the second air deflector 124 can be curved plates, and in one example, the curved plates can have a wave-shaped curve, and the curvature of the curved plates can be different or the same. Also, the first air guiding plate 122 is a straight plate and the second air guiding plate 124 may be a curved plate, or other cases, which are not limited in this respect. Therefore, the air guiding cover 12 with different shapes and sizes is adjusted to match the magnetrons 11 with different sizes.
Note that, in the case that the air guiding plate is a curved plate, the vertical direction may mean that the longitudinal direction of the first air guiding plate 122 is perpendicular to the longitudinal direction of the second air guiding plate 124.
In some embodiments, referring to FIG. 1, the magnetron 11 includes a housing 118. The housing 118 is provided with an intake opening 112 and an outlet opening 116. The top surface of the first air deflection plate 122 is flush with the top surface of the housing 118. Thus, the space occupation of the wind scooper 12 can be reduced, which is advantageous for realizing the miniaturization of the microwave cooking apparatus 100.
Specifically, the shape of the housing 118 may be a square, a rectangular parallelepiped, a cylinder, or other shapes, and is not limited herein. In the embodiment shown in fig. 1, the housing 118 has a rectangular parallelepiped shape. The air inlet 112 and the air outlet 116 may communicate with each other through the heat dissipation channel 114. In the case that the microwave cooking device 100 is in operation, the air of the fan 14 enters from the air inlet 112, the air beam 200 contacts the magnetron 11 in a large area, the magnetron 11 is cooled, and the air beam 200 carrying away the heat of the magnetron 11 can be discharged from the air outlet 116, in this embodiment, the first air deflector 122 is flush with the top surface of the casing 118, that is, the top surface of the first air deflector 122 and the top surface of the casing 118 are located on the same horizontal plane, or the height difference between the two is within a desired range, so that the first air deflector 122 does not protrude out of the casing 118, the space required for installing the air deflector 12 can be reduced, the space occupied by the microwave cooking device 100 is smaller in volume, and the microwave cooking device 100 is miniaturized.
In addition, under the operation of the microwave cooking apparatus 100, since the top surface of the first air deflector 122 is flush with the top surface of the housing 118, the air beams 200 can enter the heat dissipation channel 114 along the first air deflector 122, and because the air beams 200 generated by the fan 14 have divergence and fluidity, the first air deflector 122 can intensively guide the air beams 200 into the magnetron 11, so as to reduce the air volume emitted from the upper side of the magnetron 11, thereby effectively cooling the magnetron 11, and further improving the heat dissipation effect of the microwave cooking apparatus 100.
In some embodiments, referring to fig. 1, the fan 14 has a rotation axis X, and the magnetron 11 and the wind scooper 12 are located above the rotation axis X. In this way, the fan 14 can be used for radiating heat for other heat sources of the microwave cooking apparatus 100 besides radiating heat for the magnetron 11, so as to ensure the reliability of the microwave cooking apparatus 100 and reduce the cost.
Specifically, referring to fig. 3 and 4, the fan 14 may include fan blades 143, and the fan blades 143 may rotate around the rotation axis X. The fan 14 is formed with a fan face 144 and a sweep face 146 with the fan blades 143 rotating about the rotation axis X. The wind flux 200 emitted by the fan 14 has a divergence, and the emitted wind flux 200 has three directions of speed, namely, a radial speed B, a rotational axis speed C, and an axial speed D, along which the wind flux 200 emitted by the fan 14 diverges. Since the magnetron 11 and the wind scooper 12 are located above the rotation axis X, when the wind beam 200 moves forward, due to the widths of the first wind deflector 122 and the second wind deflector 124, the wind beam 200 in three directions meets the wall surfaces of the first wind deflector 122 and the second wind deflector 124, and then enters the magnetron 11 along the inner wall surfaces of the first wind deflector 122 and the second wind deflector 124, so that the stroke of the wind beam 200 and the divergence of the wind beam 200 can be reduced, and the loss of wind speed is reduced.
It should be noted that the swept surface 146 refers to the characteristic of the fan 14, that is, the pressure of the airflow generated by the rotation of the fan blades 143 is large, and the wind beam 200 flows to the low pressure area in the periphery during the forward flow, so that the formed surface is the swept surface 146.
In addition, referring to fig. 5, in the present embodiment, the arrow of fig. 5 may indicate the direction of the mesh beam of the fan 14, and in the process of operating the microwave cooking apparatus 100, the fan blade 143 rotates to generate the wind beam 200 driving the outside of the microwave cooking apparatus 100, and since there is no wind in the heat dissipation channel 114 of the magnetron 11, the inside of the magnetron 11 is a low-pressure region; the fan 14 outside the magnetron 11 generates a certain amount of air, so the air outlet side 142 of the fan 14 is a high pressure area, according to the characteristics of air flow, the air beam 200 can flow from high pressure to low pressure, and the guiding function of the air guiding cover 12 is added, thus the effective air amount can be increased, and the temperature of the magnetron 11 can be reduced.
In some embodiments, microwave cooking apparatus 100 includes transformer 16. The transformer 16 is located below the air-out side 142 and the axis of rotation X of the fan 14. The transformer 16 is used to power the magnetron 11. Thus, the fan 14 can dissipate heat of the transformer 16, and ensure the normal operation of the transformer 16 and the magnetron 11.
Specifically, referring to fig. 1, the transformer 16 in the microwave cooking apparatus 100 may be used to supply power to the magnetron 11 to ensure the normal operation of the magnetron 11, in this embodiment, the transformer 16 is disposed below the magnetron 11 and is also located below the rotation axis X of the fan 14, and since the transformer 16 generates heat during operation and has a certain amount of heat, the fan 14 may also dissipate heat to the transformer 16 while dissipating heat to the magnetron 11, so that the normal operation of the transformer 16 and the magnetron 11 may be ensured.
In some embodiments, the wind scooper 12 includes a mounting plate 126, and the mounting plate 126 connects the first wind deflector 122 and the magnetron 11. In this way, the wind scooper 12 is mounted.
Specifically, referring to fig. 1 and 2, in the present embodiment, the mounting plate 126 may be a straight plate, and the shape may be a flattened rectangular parallelepiped, a square, a circle, or other shapes. In other embodiments, the mounting plate 126 may be a curved plate, the width of the curved plate may be different, and the curvature of the mounting plate 126 may also be different. And is not particularly limited herein. The first air deflector 122 and the magnetron 11 are fixedly connected by a mounting plate 126, so that the first air deflector 122 can be firmly mounted at the air inlet 112 of the magnetron 11. The mounting plate 126 may be provided with a mounting hole 1262, and the air guide cover 12 may be mounted through the mounting hole 1262.
In some embodiments, the mounting plate 126 is perpendicular to the second air deflection plates 124. In this way, the second air deflectors 124 are conveniently arranged along the length direction A-A of the heat dissipation channel 114.
Specifically, referring to fig. 2 and 5, the mounting plate 126 is perpendicular to the second air deflector 124. Typically, the length of the heat dissipation channel 114 is perpendicular to the top surface of the housing 118. In the process of installing the wind scooper 12, the installation plate 126 is installed in parallel with the top surface of the housing of the magnetron 11, so that the second wind deflector 124 is arranged along the length direction a-a of the heat dissipation channel 114, which is beneficial to the installation direction of the second wind deflector 124 and further to adjust the direction of the wind beam 200, so that the direction of the wind beam 200 is the same as the direction of the heat dissipation channel 114, the contact area between the effective wind volume and the magnetron 11 is increased, and further the heat dissipation efficiency is increased.
In some embodiments, the magnetron 11 is provided with a plurality of heat dissipation channels 114, the plurality of heat dissipation channels 114 being arranged along a direction A-A perpendicular to the length of the heat dissipation channels 114. Thus, the heat dissipation effect is improved.
Specifically, referring to fig. 1, the heat dissipation channel 114 may be formed by a plurality of heat dissipation fins (not shown) uniformly spaced apart, and the plurality of heat dissipation channels 114 may be installed along a direction a-a perpendicular to the length direction of the heat dissipation channel 114, such as the direction E-E shown in fig. 1, so that the second air guiding plate 124 may rectify and collect the wind beams 200 of the plurality of heat dissipation channels 114, thereby increasing the effective contact area between the heat dissipation channel 114 and the wind beams 200, and further improving the heat dissipation effect.
