For example, during the operation of an induction cooker or induction range, the sources of noise generated may include electromagnetic noise, fan duct noise, and boiling noise.

DETAILED DESCRIPTION

[0073] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

If the specific posture changes, the directional indication will also change accordingly.

[0077] Most cooking equipment will inevitably generate noise during operation, affecting the user experience. For example, during the operation of an induction cooker or induction cooker, the sources of noise generated may include electromagnetic noise, fan duct noise, and boiling noise. When running to the middle and late stages, the dominant noise source is the fan duct noise. Optimizing the fan and optimizing the duct can reduce the fan duct noise of the induction cooker. From the perspective of optimizing the fan, induction cookers on the market currently use axial flow fans or centrifugal fans for heat dissipation. The fan speed can be reduced by designing an axial flow fan with a larger air volume and better performance or using a centrifugal fan with a larger air pressure to replace the axial flow fan or centrifugal fan to achieve noise reduction. However, this method has limitations, that is, the axial flow fan in the induction cooker will not blow the heat dissipation to the heating element until the air reaches the stove panel and changes direction. This method will not only affect the heat dissipation effect, but will also inevitably convert part of the kinetic energy of the air into noise. The cooking equipment provided by the embodiment of the present application can improve the above problems. The cooking equipment provided by the embodiment of the present application uses a cross-flow fan instead of an axial flow fan or a centrifugal fan to improve the noise problem of the cooking equipment during operation to a certain extent.

[0078] The axis of the cross-flow fan is relatively long. During use, the radiation area of ​​the wind blown out by the cross-flow fan is large and not concentrated, resulting in part of the wind directly flowing out of the shell without exchanging heat with the components, resulting in poor heat dissipation effect of the entire cooking device. The cooking device provided in the embodiment of the present application can improve the above-mentioned problem. The cooking device provided in the embodiment of the present application can be equipped with different heat dissipation channels in the shell, and different components can be arranged in different heat dissipation channels to form zoned heat dissipation, which can increase the contact between the wind blown out from the cross-flow fan and different components, improve the heat dissipation effect of the components, and improve the heat dissipation effect of the entire cooking device.

[0079] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0080] See also Figure 1 and Figure 2 The embodiment of the present application provides a cooking device 100. The cooking device 100 provided by the embodiment of the present application can perform zoned heat dissipation, and can improve the contact between the wind blown out from the cross-flow fan 120 and different component assemblies 130, thereby improving the heat dissipation effect on the component assemblies 130 and improving the heat dissipation effect of the entire cooking device 100.

[0081] The cooking device 100 may be an induction cooker, an induction range or other device that uses electric heating to cook.

[0082] In the embodiment of the present application, the cooking device 100 includes: a shell 110, a cross-flow fan 120, a partition assembly 160 and a component assembly 130, the shell 110 has a first air outlet 111 and a second air outlet 112; the cross-flow fan 120 is arranged in the shell 110 and is arranged close to the first air outlet 111; the partition assembly 160 is arranged in the shell 110, and in the axial direction of the cross-flow fan 120, the partition assembly 160 divides the internal cavity of the shell 110 into a first heat dissipation channel 113 and a second heat dissipation channel 114, and the first heat dissipation channel 113 and the second heat dissipation channel 114 are both connected to the first air outlet 111 and the second air outlet 112; the electronic control assembly 134 includes a heating element 132 and an electronic control assembly 134, the heating element 132 is arranged in the first heat dissipation channel 113, and the electronic control assembly 134 is arranged in the second heat dissipation channel 114.

[0083] Among them, among the first air outlet 111 and the second air outlet 112, one of them can be used as an air inlet and the other as an air outlet. The first air outlet 111 can be used as an air inlet and the second air outlet 112 can be used as an air outlet, or the first air outlet 111 can be used as an air outlet and the second air outlet 112 can be used as an air inlet.

[0084] Since the cross-flow fan 120 is disposed closer to the first air port 111 than the second air port 112, if the entire cooking device 100 dissipates heat by blowing air, the first air port 111 serves as an air inlet and the second air port 112 serves as an air outlet. If the entire cooking device 100 dissipates heat by suction, the first air port 111 serves as an air outlet and the second air port 112 serves as an air inlet. Regardless of which of the first air port 111 and the second air port 112 serves as the air inlet or the air outlet, after the cross-flow fan 120 is started, an airflow can be formed between the first air port 111 and the second air port 112. The airflow can exchange heat with the component assembly 130 through the component assembly 130, taking away the heat of the component assembly 130, thereby dissipating heat from the component assembly 130.

[0085] For the convenience of description in the embodiment of the present application, the entire cooking device 100 adopts the blowing method to dissipate heat as an example, that is, the first air vent 111 is used as the air inlet and the second air vent 112 is used as the air outlet. When the cooking device 100 adopts the suction method to dissipate heat, the same can be applied.

[0086] As for the position of the crossflow fan 120, the crossflow fan 120 can be set at the first air port 111 to improve the drainage effect of the crossflow fan 120. The crossflow fan 120 can also be set in the housing 110 at a certain distance from the first air port 111 to ensure that it is closer to the first air port 111.

[0087] The heating element 132 is a component that provides a heat source to the outside of the entire cooking device 100, and can be a coil. The volume of the heating element 132 is relatively large. Under the same volume, in order to ensure the heating power of the heating element 132, the layout space of the electronic control component 134 will be compressed as much as possible. If the space of the electronic control component 134 is small, it is easy to cause heat accumulation and untimely heat dissipation. If the electronic control component 134 does not dissipate heat in time, the local temperature of the electronic control component 134 is likely to be too high and components are damaged.

[0088] Since the temperature of the heating element 132 is relatively high, the temperature of the wind blown out from the cross-flow fan 120 after heat exchange with the heating element 132 is relatively high. If the wind after heat exchange with the heating element 132 passes through the electronic control component 134 again, it is easy to not only fail to reduce the temperature of the radiator 134b and the circuit board 134a, but may also cause the temperature of the electronic control component 134 to rise, causing damage to the components on the electronic control component 134.

[0089] In the embodiment of the present application, the internal space of the shell 110 is divided into a first heat dissipation channel 113 and a second heat dissipation channel 114 by a partition assembly 160, the heat generating element 132 is arranged in the first heat dissipation channel 113, and the electronic control component 134 is arranged in the second heat dissipation channel 114, and the first heat dissipation channel 113 and the second heat dissipation channel 114 are arranged in the axial direction of the cross-flow fan 120. Since the axis of the cross-flow fan 120 is relatively long, the wind blown out of the cross-flow fan 120 can directly enter the first heat dissipation channel 113 and the second heat dissipation channel 114. That is to say, the wind blown out of the cross-flow fan 120 directly enters the first heat dissipation channel 113 and the second heat dissipation channel 114 before heat exchange with other components, and can directly contact the heat generating element 132 arranged in the first heat dissipation channel 113 and directly contact the electronic control component 134 arranged in the second heat dissipation channel 114, and can take away more heat from the heat generating element 132 and the electronic control component 134, thereby improving the heat dissipation effect.

[0090] In the embodiment of the present application, the interior of the shell 110 is divided into an independent first heat dissipation channel 113 and a second heat dissipation channel 114, so that the heat dissipation of the heating element 132 and the heat dissipation of the electronic control component 134 are independent of each other, and the wind after heat exchange with the heating element 132 is avoided as much as possible from flowing to the electronic control component 134, which can improve the heat dissipation effect of the heating element 132 and the electronic control component 134.

[0091] See also Figure 3 and Figure 4In some embodiments, the electronic control component 134 includes a heat sink 134b and a circuit board 134a, the second heat dissipation channel 114 includes a first heat dissipation section 114a and a second heat dissipation section 114b that are interconnected, the first heat dissipation section 114a is arranged close to the cross-flow fan 120, the second heat dissipation section 114b is arranged close to the second air outlet 112, the heat sink 134b is arranged in the first heat dissipation section 114a, and the circuit board 134a is arranged in the second heat dissipation section 114b.

[0092] Among them, the first air outlet 111 and the second air outlet 112 are arranged on two opposite side walls of the shell 110. For the convenience of description, the axial direction along the cross-flow fan 120 can be defined as the length direction of the cooking device 100, the direction from the first air outlet 111 to the second air outlet 112 can be defined as the width direction of the cooking device 100, and the direction from the top wall to the bottom wall of the shell 110 can be defined as the height direction of the cooking device 100.

[0093] The heating element 132 and the electronic control component 134 are arranged side by side in the axial direction of the cross-flow fan 120, which means that the whole formed by the heat sink 134b and the circuit board 134a is arranged side by side with the heating element 132 in the length direction, while the heat sink 134b and the circuit board 134a are arranged side by side in the width direction, the heat sink 134b is arranged closer to the cross-flow fan 120, and the circuit board 134a is arranged closer to the second air outlet 112.

[0094] Among them, the circuit board 134a is mainly used to install the electronic components of the entire cooking device. The heating element 132 will generate a large amount of heat during operation, and the electronic components will also generate a certain amount of heat during operation. If the heat of the circuit board 134a is too high, some electronic components on the circuit board 134a may not work properly. In order to ensure that the electrical components on the circuit board 134a can work properly, the radiator 134b will be used to dissipate the heat of the circuit board 134a. Part of the heat on the circuit board 134a will be transferred to the radiator 134b, and then dissipated by the radiator 134b.

[0095] The second heat dissipation section 114b is arranged close to the second air outlet 112, and the first heat dissipation section 114a is arranged close to the cross-flow fan 120, which means that the radiator 134b is arranged closer to the cross-flow fan 120, and the radiator 134b is arranged between the cross-flow fan 120 and the circuit board 134a. The radiator 134b is mainly used to dissipate heat for the circuit board 134a. The heat exchange speed of the radiator 134b is higher than that of the circuit board 134a. The flow rate of the wind around the cross-flow fan 120 is the largest. Among the circuit board 134a and the radiator 134b, the radiator 134b is arranged close to the cross-flow fan 120, so that more wind can flow to the radiator 134b, and more wind can flow to the surrounding of the radiator 134b to exchange heat with the radiator 134b, thereby increasing the contact time and contact area with the radiator 134b, thereby improving the heat dissipation effect.

[0096] In some embodiments, in a direction from the first air outlet 111 to the second air outlet 112 , a length of the first heat dissipation section 114 a in an axial direction of the cross-flow blower 120 gradually decreases.

[0097] In the direction from the first air outlet 111 to the second air outlet 112, that is, in the width direction of the cooking device 100, the length of the first heat dissipation section 114a in the axial direction of the cross-flow fan 120 gradually decreases. In other words, in the width direction of the cooking device 100, the first heat dissipation section 114a is in a trumpet shape, and the section close to the second air outlet 112 is smaller than the section close to the first air outlet 111. In other words, the end of the first heat dissipation section 114a close to the cross-flow fan 120 has a longer length in the axial direction of the cross-flow fan 120, and the end away from the cross-flow fan 120 has a shorter length in the axial direction of the cross-flow fan 120.

[0098] The end of the first heat dissipation section 114a close to the cross-flow fan 120 has a greater length in the axial direction of the cross-flow fan 120, which can enable more wind blown out by the cross-flow fan 120 to enter the first heat dissipation section 114a, thereby increasing the amount of wind entering the first heat dissipation section 114a, and enabling more wind blown out by the cross-flow fan 120 to exchange heat with the radiator 134b in the first heat dissipation section 114a, thereby increasing the amount of contact with the radiator 134b, and being able to take away more heat from the radiator 134b, thereby improving the heat dissipation effect on the radiator 134b.

[0099] The end of the first heat dissipation section 114a away from the cross-flow fan 120 has a smaller length in the axial direction of the cross-flow fan 120, so that the wind entering the second heat dissipation section 114b is more concentrated, and the wind can be blown toward the circuit board 134a more concentratedly, thereby increasing the flow rate of the wind in the second heat dissipation section 114b and improving the heat dissipation effect on the circuit board 134a to a certain extent.

[0100] In some embodiments, in the axial direction of the cross-flow blower 120 , the length of the first heat dissipation segment 114 a close to one end of the cross-flow blower 120 is greater than 1 / 3 of the length of the cross-flow blower 120 .

[0101] The longer the length of the first heat dissipation section 114a close to the cross-flow fan 120, the more air volume enters the first heat dissipation section 114a. If the length of one end of the first heat dissipation section 114a close to the cross-flow fan 120 in the axial direction of the cross-flow fan 120 is greater than 1 / 3 of the length of the cross-flow fan 120, more wind can enter the first heat dissipation section 114a, increasing the air volume entering the first heat dissipation section 114a, allowing more wind to flow around the radiator 134b, taking away more heat from the radiator 134b, and improving the heat dissipation effect of the radiator 134b.

[0102] The above mainly describes the layout and position of the first heat dissipation channel 113 and the second heat dissipation channel 114. The specific positions of the first heat dissipation channel 113 and the second heat dissipation channel 114, as well as how the first heat dissipation section 114a and the second heat dissipation section 114b are formed will be described in detail in combination with the specific structure of the partition assembly 160. The following only provides one or several implementation methods of the first heat dissipation channel 113 and the second heat dissipation channel 114, and other implementation methods can be referred to and deduced accordingly.

[0103] In some embodiments, the partition assembly 160 includes a first partition 161, a second partition 163 and a third partition 165 which are arranged in sequence in the axial direction of the cross-flow blower 120, and the gap between the first partition 161 and the second partition 163 forms a first heat dissipation channel 113, and the gap between the second partition 163 and the third partition 165 forms a second heat dissipation channel 114.

[0104] The first partition plate 161, the second partition plate 163 and the third partition plate 165 are arranged in sequence in the axial direction of the cross-flow fan 120, that is, the second partition plate 163 is arranged between the first partition plate 161 and the third partition plate 165, one side of the second partition plate 163 and the first partition plate 161 form a first heat dissipation channel 113, and the other side of the second partition plate 163 and the third partition plate 165 form a second heat dissipation channel 114.

[0105] The spacing distance between the first partition 161 and the second partition 163, that is, the length of the first heat dissipation channel 113 in the axial direction of the cross-flow fan 120, can be set according to the size of the heating element 132, and can be slightly larger than the size of the heating element 132, so as to ensure that the heating element 132 can be installed in the first heat dissipation channel 113. Similarly, the spacing distance between the second partition 163 and the third partition 165, that is, the length of the second heat dissipation channel 114 in the axial direction of the cross-flow fan 120, can be set according to the size of the electric control component 134, and can be slightly larger than the size of the electric control component 134, so as to ensure that the electric control component 134 can be placed in the second heat dissipation channel 114.

[0106] The first partition plate 161 and the third partition plate 165 are generally disposed at both ends of the housing 110 in the axial direction of the crossflow blower 120. The first partition plate 161 may be a separate structure, or an end wall of the housing 110 may be directly configured as the first partition plate 161. Similarly, the second partition plate 163 may be a separate structure, or another end wall of the housing 110 may be directly configured as the second partition plate 163.

[0107] In some embodiments, the first air outlet 111 and the second air outlet 112 are respectively disposed on two opposite side walls of the housing 110 , and the first partition plate 161 , the second partition plate 163 and the third partition plate 165 extend from the first air outlet 111 to the second air outlet 112 .

[0108] The direction from the first air outlet 111 to the second air outlet 112 is the width direction of the cooking device 100, and the first partition 161, the second partition 163 and the third partition 165 extend from the first air outlet 111 to the second air outlet 112, so that the air blown out by the cross-flow fan 120 can be directly guided to the second air outlet 112 and blown out from the second air outlet 112 to the outside of the shell 110, thereby reducing the risk of the air in the first heat dissipation channel 113 that has undergone heat exchange with the heating element 132 and then entering the second heat dissipation channel 114. Similarly, the risk of the air in the second heat dissipation channel 114 that has undergone heat exchange with the electronic control component 134 and then entering the second heat dissipation channel 114 is also reduced.

[0109] The first baffle 161, the second baffle 163 and the third baffle 165 extend from the first air outlet 111 to the second air outlet 112, and can guide the wind in the first heat dissipation channel 113 and the second heat dissipation channel 114. The wind in the first heat dissipation channel 113 can flow along the extending direction of the first baffle 161 and the second baffle 163, and the wind in the second heat dissipation channel 114 can flow along the extending direction of the second baffle 163 and the third baffle 165.

[0110] In some embodiments, the baffle assembly 160 is spaced apart from the crossflow fan 120. At least the second baffle 163 is spaced apart from the crossflow fan 120, that is, the first heat dissipation channel 113 and the second heat dissipation channel 114 can be connected at one end close to the crossflow fan 120, and the wind at the crossflow fan 120 is basically the wind that has not exchanged heat with the heating element 132 or the electronic control assembly 134. During the operation of the crossflow fan 120, the wind blown out by the crossflow fan 120 can flow between the first heat dissipation channel 113 and the second heat dissipation channel 114 before entering the first heat dissipation channel 113 and the second heat dissipation channel 114, ensuring that the wind pressure in the first heat dissipation channel 113 and the second heat dissipation channel 114 is basically the same. When any one of the first heat dissipation channel 113 and the second heat dissipation channel 114 is blocked, it is possible to avoid the situation where the wind pressure in the first heat dissipation channel 113 or the second heat dissipation channel 114 is too high, resulting in damage to components.

[0111] Due to the different sizes of the heating element 132 and the electronic control component 134, in order to install the heating element 132 in the first heat dissipation channel 113 and the electronic control component 134 in the second heat dissipation channel 114, the lengths of the first heat dissipation channel 113 and the second heat dissipation channel 114 in the axial direction of the cross-flow fan 120 are different. The corresponding length of the cross-flow fan 120 in the first heat dissipation channel 113 is longer, and the second partition plate 163 is arranged at an end close to the cross-flow fan 120 and spaced from the cross-flow fan 120, so that the first heat dissipation channel 113 is connected to the second heat dissipation channel 114, and the wind blown out of the cross-flow fan 120 corresponding to the first heat dissipation channel 113 can be blown to the second heat dissipation channel 114, thereby increasing the air volume in the second heat dissipation channel 114 and allowing more wind to enter the vicinity of the electronic control component 134, thereby improving the heat dissipation effect on the electronic control component 134.

[0112] Of course, the first partition 161 and the third partition 165 can also be spaced apart from the cross-flow fan 120, so that wind from other positions in the shell 110 can enter the first heat dissipation channel 113 and the second heat dissipation channel 114, increase the air volume entering the first heat dissipation channel 113 and the second heat dissipation channel 114, and improve the heat dissipation effect on the heating element 132 and the electronic control component 134.

[0113] The spacing between the first partition 161, the second partition 163, and the third partition 165 and the cross-flow fan 120 is greater than 1 mm. At least the spacing between the end of the second partition 163 close to the cross-flow fan 120 and the cross-flow fan 120 is greater than 1 mm. This allows the connection area between the first heat dissipation channel 113 and the second heat dissipation channel 114 to be larger, increases the flow of unheated air in the first heat dissipation channel 113 and the second heat dissipation channel 114, and improves the utilization rate of the air blown out by the cross-flow fan 120.

[0114] In some embodiments, the baffle assembly 160 is spaced apart from the second air outlet 112 or connected to the housing 110 at the second air outlet 112. That is, the first baffle 161, the second baffle 163 and the third baffle 165 can be spaced apart from the second air outlet 112, or directly connected to the housing 110 at the second air outlet 112.

[0115] The wind close to the second air outlet 112 is basically the wind that has exchanged heat with the heating element 132 or the electronic control component 134. The first partition 161, the second partition 163 and the third partition 165 are directly extended to the second air outlet 112, so that the wind after heat exchange can be directly discharged from the second air outlet 112 to the outside of the shell 110, reducing the flow of the wind after heat exchange in the first heat dissipation channel 113 and the second heat dissipation channel 114, so that the heating element 132 and the electronic control component 134 can dissipate heat independently, reducing the mutual influence between the heating element 132 and the electronic control component 134.

[0116] Of course, in addition to this, the first partition 161, the second partition 163 and the third partition 165 may also have a certain gap with the second air outlet 112, but the gap should not be too large to avoid the flow of wind after heat exchange between the first heat dissipation channel 113 and the second heat dissipation channel 114.

[0117] In some embodiments, the minimum distance between the first baffle 161 and the third baffle 165 is greater than the length of the second air outlet 112 in the axial direction of the crossflow fan 120. This allows the entire first heat dissipation channel 113 and the second heat dissipation channel 114 to be located within the range of the second air outlet 112, so that the wind after heat exchange with the heating element 132 and the electronic control component 134 can be blown out from the second air outlet 112 in time, reducing the possibility of the wind after heat exchange flowing in the housing 110, and reducing the impact of the high temperature wind after heat exchange on other components.

[0118] In some embodiments, the second partition plate 163 includes a first partition section 163 a and a second partition section 163 b that are connected to each other. The first partition section 163 a is disposed close to the cross-flow blower 120 , and the second partition section 163 b is disposed close to the second air port 112 .

[0119] The third partition plate 165 includes a third partition section 165 a and a fourth partition section 165 b that are connected to each other. The third partition section 165 a is disposed close to the cross-flow fan 120 , and the fourth partition section 165 b is disposed close to the second air port 112 .

[0120] The electronic control component 134 includes a heat sink 134b and a circuit board 134a. The first partition section 163a, the third partition section 165a and the shell 110 form a first heat dissipation section 114a. The second partition section 163b, the fourth partition section 165b and the shell 110 form a second heat dissipation section 114b. The heat sink 134b is arranged in the first heat dissipation section 114a, and the circuit board 134a is arranged in the second heat dissipation section 114b.

[0121] The first partition section 163a and the second partition section 163b may be integrally formed or separately formed, and the extension directions of the first partition section 163a and the second partition section 163b may be the same or different, that is, the first partition section 163a and the second partition section 163b may be arranged at an angle.

[0122] Similarly, the third partition segment 165a and the fourth partition plate can be integrally formed or separately formed, and the extension direction of the third partition segment 165a and the fourth partition segment 165b can be the same or different, that is, the third partition segment 165a and the fourth partition segment 165b can be set at an angle.

[0123] As for how the heat sink 134b is arranged in the first heat dissipation section 114a, how the circuit board 134a is arranged in the second heat dissipation section 114b, and the positional relationship between the first heat dissipation section 114a and the second heat dissipation section 114b, please refer to the above description and will not be repeated here.

[0124] See also Figure 5 and Figure 6 In some embodiments, the shell 110 includes a bottom shell 116 and an upper cover 117, the upper cover 117 is connected to the bottom shell 116, the partition assembly 160 is arranged on the bottom shell 116, the upper cover 117 includes a cover plate 117a and a first air guide portion 117b and a second air guide portion 117c spaced apart on the cover plate 117a, the upper cover 117 is arranged above the radiator 134b, the first air guide portion 117b and the first partition section 163a are arranged correspondingly, the second air guide portion 117c and the third partition section 165a are arranged correspondingly, and the cover plate 117a, the first air guide portion 117b, the second air guide portion 117c, the bottom shell 116, the first partition section 163a and the third partition section 165a together form the first heat dissipation section 114a.

[0125] The upper cover 117 is arranged above the bottom shell 116, so that the first heat dissipation section 114a presents a closed structure in the height direction of the shell 110, which can play a certain guiding role in the wind blown out by the cross-flow fan 120, so that the wind blown out by the cross-flow fan 120 can enter the first heat dissipation section 114a more, increase the wind volume entering the first heat dissipation section 114a, and enable more wind to enter the surroundings of the radiator 134b and the circuit board 134a, thereby improving the heat dissipation effect on the radiator 134b and the circuit board 134a.

[0126] The housing 110 further includes a heat conducting plate 118 , which is disposed above the upper cover 117 and is used to quickly conduct heat generated by the heating element 132 for heating cooking.

[0127] See also Figure 3 and Figure 4 In some embodiments, a support plate 167 is disposed in the first heat dissipation section 114 a , and the radiator 134 b is mounted on the support plate 167 , so that the radiator 134 b is spaced apart from the bottom wall of the housing 110 .

[0128] The radiator 134b is installed on the support plate 167 so that there is a certain gap between the radiator 134b and the bottom wall of the shell 110, so that the wind in the first heat dissipation section 114a can partially enter the bottom of the radiator 134b, which can dissipate the heat from the bottom of the radiator 134b and facilitate the arrangement and installation of the radiator 134b.

[0129] In some embodiments, in the direction from the first air outlet 111 toward the second air outlet 112 , at least one of the first partition section 163 a and the third partition section 165 a is tilted toward the other direction.

[0130] In the direction from the first air outlet 111 to the second air outlet 112 , the first partition plate 161 is tilted toward the third partition section 165 a . In other words, in the direction from the second air outlet 112 to the first air outlet 111 , the first partition section 163 a is tilted toward the first heat dissipation channel 113 .

[0131] The heating element 132 is mostly a disc-shaped structure. There are some blank areas on the side of the heating element 132 close to the second heat dissipation channel 114. The first partition section 163a is tilted toward the first heat dissipation channel 113, so that the first heat dissipation section 114a is not a regular rectangle. The first heat dissipation section 114a can partially extend into the area outside the disc of the heating element 132, which can reasonably utilize the space under the heating element 132, increase the layout position of the radiator 134b, and increase the heat dissipation area of ​​the radiator 134b.

[0132] In addition, in the direction from the first air outlet 111 to the second air outlet 112, the third partition section 165a can also be inclined toward the first partition section 163a, so that the entire first heat dissipation section 114a is roughly in the shape of a trumpet, and the end of the first heat dissipation section 114a close to the cross-flow fan 120 is longer in the axial direction of the cross-flow fan 120, which can enable more wind blown by the cross-flow fan 120 to enter the first heat dissipation section 114a, increase the air volume entering the first heat dissipation section 114a, and enable the wind blown by the cross-flow fan 120 to exchange heat with the radiator 134b in the first heat dissipation section 114a more, increase the contact amount with the radiator 134b, and can take away more heat from the radiator 134b, thereby improving the heat dissipation effect of the radiator 134b.

[0133] The end of the first heat dissipation section 114a away from the cross-flow fan 120 has a smaller length in the axial direction of the cross-flow fan 120, so that the wind entering the second heat dissipation section 114b is more concentrated, and the wind can be blown toward the circuit board 134a more concentratedly, thereby increasing the flow rate of the wind in the second heat dissipation section 114b and improving the heat dissipation effect on the circuit board 134a to a certain extent.

[0134] In some embodiments, the spacing distance between the first partition 163a and the third partition 165a near one end of the cross flow fan 120 is greater than or equal to 1 / 3 of the length of the cross flow fan 120. That is, the length of the first heat dissipation segment 114a in the axial direction of the cross flow fan 120 is greater than or equal to 1 / 3 of the length of the cross flow fan 120.

[0135] The longer the length of the first heat dissipation section 114a close to the cross-flow fan 120, the more air volume enters the first heat dissipation section 114a. If the length of one end of the first heat dissipation section 114a close to the cross-flow fan 120 in the axial direction of the cross-flow fan 120 is greater than 1 / 3 of the length of the cross-flow fan 120, more wind can enter the first heat dissipation section 114a, increasing the air volume entering the first heat dissipation section 114a, allowing more wind to flow around the radiator 134b, taking away more heat from the radiator 134b, and improving the heat dissipation effect of the radiator 134b.

[0136] In some embodiments, the height of the first partition 163 a is lower than the height of the second partition 163 , and a portion of the heat sink 134 b extends into the first heat dissipation channel 113 .

[0137] The first partition section 163a is mainly used for installing the radiator 134b. The height of the first partition 161 is set relatively low so that part of the radiator 134b can extend into the first heat dissipation channel 113, and the unused space under the disc-shaped heating element 132 can be reasonably utilized, so that the internal layout of the entire shell 110 is more compact, and the volume of the entire cooking device 100 can be reduced as much as possible.

[0138] See also Figure 7 and Figure 8 In some embodiments, the projections of the heat sink 134 b and the heat generating element 132 on the bottom wall of the housing 110 partially overlap.

[0139] The projections of the radiator 134b and the heating element 132 on the bottom wall of the shell 110 are at least partially overlapped, which means that the radiator 134b and the heating element 132 are at least partially overlapped in the height direction of the shell 110, that is, the radiator 134b and the heating element 132 at least partially overlap together. Compared with the side-by-side arrangement of the radiator 134b and the heating element 132, the occupied space in the width and length directions of the shell 110 can be reduced, and at least one of the width and length of the entire cooking device 100 can be reduced. While ensuring the operation of the heating element 132 and the radiator 134b, the volume of the cooking device 100 can be reduced, and the occupied space of the cooking device 100 can be reduced.

[0140] The projections of the radiator 134b and the heating element 132 on the bottom wall of the shell 110 are at least partially overlapped. Part of the radiator 134b may overlap with part of the heating element 132, or all of the radiator 134b may overlap with part of the heating element 132, or part of the radiator 134b may overlap with all of the heating element 132.

[0141] See also Figure 8 and Fig. 9 In some embodiments, the heat sink 134b includes a heat dissipation body 134c, a plurality of first fins 134d and a plurality of second fins 134e connected to the heat dissipation body 134c, the plurality of first fins 134d and the plurality of second fins 134e are arranged in sequence at intervals, the heat dissipation body 134c is connected to the circuit board 134a, and the projections of the second fins 134e and the heat generating element 132 on the bottom wall of the housing 110 at least partially overlap.

[0142] The heat dissipation body 134c is the basic component of the entire heat sink 134b, providing a mounting base for the plurality of first fins 134d and the plurality of second fins 134e, and forming a heat dissipation channel between two adjacent first fins 134d, between two adjacent second fins 134e, or between adjacent first fins 134d and second fins 134e.

[0143] Among them, the radiator 134b is mainly used to dissipate heat for the circuit board 134a. If the entire radiator 134b is overlapped with the heating element 132, since the temperature of the heating element 132 will be very high during operation, the radiator 134b is overlapped with the heating element 132, which will cause the ambient temperature around the radiator 134b to be very high. The radiator 134b cannot quickly dissipate heat for the circuit board 134a. Therefore, the first fin 134d and the heating element 132 can be staggered, and the second fin 134e and the heating element 132 can be overlapped. The first fin 134d mainly exchanges heat with the wind at other positions in the shell 110 to dissipate heat for the circuit board 134a, and the second fin 134e can reduce a certain amount of occupied space while dissipating heat.

[0144] Since the heat sink 134b and the heat generating element 132 are arranged in the axial direction of the cross-flow fan 120, and the first fin 134d and the heat generating element 132 are at least partially overlapped, the first fin 134d and the second fin 134e are also arranged in the axial direction of the cross-flow fan 120, that is, the heat dissipation channel extends from the direction of the first air outlet 111 to the direction of the second air outlet 112.

[0145] During the operation of the cross-flow fan 120, the wind blown out from the cross-flow fan 120 can directly blow onto the first fin 134d and the second fin 134e, flow to the second air outlet 112 through the heat dissipation channel, and directly contact the first fin 134d and the second fin 134e respectively, thereby increasing the contact area with the first fin 134d and the second fin 134e respectively, reducing the resistance of the wind passing through the heat dissipation channel, and being able to take away more heat from the first fin 134d and the second fin 134e, thereby improving the heat dissipation effect.

[0146] As for the ratio between the first fin 134d and the second fin 134e, it can be set according to the volume of the entire cooking device 100. If the volume of the cooking device 100 is large, more first fins 134d can be provided, and fewer second fins 134e can be provided. If the volume of the cooking device 100 is small, fewer first fins 134d can be provided, and more second fins 134e can be provided.

[0147] In some embodiments, the second fin 134 e is spaced apart from the heat generating element 132 .

[0148] The second fin 134e and the heating element 132 are spaced apart so that there is a gap between the second fin 134e and the heating element 132. Wind blown out from the cross-flow fan 120 can flow toward the circuit board 134a through the gap between the second fin 134e and the heating element 132, so that more wind can flow toward the circuit board 134a, thereby improving the heat dissipation effect on the circuit board 134a.

[0149] Similarly, the height of the gap between the second fin 134e and the heating element 132 can be comprehensively considered based on the height of the entire machine, the heat dissipation requirements of the radiator 134b, etc. For example, if the height of the entire cooking device 100 is high, the gap between the second fin 134e and the heating element 132 can be set larger. If the height of the entire cooking device 100 is short, the gap between the second fin 134e and the heating element 132 can be set smaller.

[0150] In some embodiments, the height of the first fin 134d is greater than the height of the second fin 134e.

[0151] Since the second fin 134e and the heating element 132 are overlapped, the second fin 134e and the heating element 132 need to be overlapped in the height direction of the cooking device 100, which requires a loss of some length of the second fin 134e in the height direction. The first fin 134d and the heating element 132 are offset, so the first fin 134d can be set longer. The longer first fin 134d can increase the contact area of ​​the wind flowing between the first air outlet 111 and the second air outlet 112, thereby improving the heat dissipation effect.

[0152] In some embodiments, the second fin 134 e is disposed below the heat generating element 132 .

[0153] The heating element 132 is the main component of the entire cooking device 100 for outputting heat to the outside. The upper surface of the cooking device 100 heats the food to be cooked. If the second fin 134e is arranged above the heating element 132, it will affect the heat supply of the heating element 132. The second fin 134e is arranged below the heating element 132, which can dissipate heat below the heating element 132 without affecting the operation of the heating element 132, and can prevent the temperature below the heating element 132 from being too high and affecting the operation of other components.

[0154] See also Fig.10 In some embodiments, the minimum distance between the heat sink 134b and the bottom wall of the housing 110 is a first height h1; the crossflow fan 120 has a crossflow outlet 125, and the minimum distance between the crossflow outlet 125 and the bottom wall of the housing 110 is a second height h2;

[0155] The first height h1 is greater than or equal to the second height h2.

[0156] The minimum distance between the heat sink 134b and the bottom wall of the housing 110 is the distance between the bottom of the heat sink 134b and the bottom wall of the housing 110, and the minimum distance between the crossflow outlet 125 and the bottom wall of the housing 110 is the distance between the bottom of the crossflow outlet 125 and the bottom wall of the housing 110. If the first height h1 is greater than or equal to the second height h2, it means that the bottom of the heat sink 134b is located in the projection area of ​​the crossflow outlet 125, that is, the heat sink 134b is located in the air outlet radiation area of ​​the crossflow outlet 125, so that the wind blown by the crossflow fan 120 can directly blow to the heat sink 134b and directly contact the first fin 134d and the second fin 134e of the heat sink 134b, thereby increasing the contact time and contact area with the heat sink 134b, thereby improving the heat dissipation effect.

[0157] In some embodiments, the minimum distance between the circuit board 134a and the bottom wall of the housing 110 is a third height h3, the crossflow fan 120 has a crossflow outlet 125, and the maximum distance between the crossflow outlet 125 and the bottom wall of the housing 110 is a fourth height h4;

[0158] The third height h3 is greater than or equal to the second height h2, and less than or equal to the fourth height h4.

[0159] The minimum distance between the circuit board 134a and the bottom wall of the housing 110 is the distance between the bottom of the circuit board 134a and the bottom wall of the housing 110. Usually, a heating element is arranged on the circuit board 134a. The bottom of the circuit board 134a refers to the bottom of the heating device. In order to improve the heat dissipation efficiency, the heating element can be arranged below the radiator 134b. The maximum distance between the cross-flow air outlet 125 and the bottom wall of the housing 110 is the distance between the top of the cross-flow air outlet 125 and the bottom wall of the housing 110. The third height h3 is greater than or equal to the second height h2, and less than or equal to the fourth height h4, which means that the third height h3 is between the second height h2 and the fourth height h4, that is, the projection part of the heating element on the cross-flow air outlet 125 is located in the area of ​​the cross-flow air outlet 125, so that the wind blown out from the cross-flow fan 120 can directly blow onto the circuit board 134a, can contact at least part of the surface of the heating device on the circuit board 134a, directly take away the heat generated by the heating element, and improve the heat dissipation effect.

[0160] In some embodiments, the maximum distance between the cross-flow outlet 125 and the bottom wall of the housing 110 is a fourth height h4, and the maximum distance between the heat sink 134b and the bottom wall of the housing 110 is a fifth height h5;

[0161] The fifth height h5 is greater than and equal to the fourth height h4.

[0162] Similarly, the maximum height between the heat sink 134b and the bottom wall of the shell 110 is the distance between the top of the heat sink 134b and the bottom wall of the shell 110, that is, the top of the heat sink 134b is located outside the air outlet area of ​​the cross-flow outlet 125 or is flush with the top of the cross-flow outlet 125, that is, the heat sink 134b can fill the area above the cross-flow outlet 125. During the operation of the cross-flow fan 120, the wind blown out from the cross-flow outlet 125 of the cross-flow fan 120 can contact the heat sink 134b, and the possibility of the wind blown out from the cross-flow outlet 125 colliding with the top of the heat sink 134b can be reduced, and the resistance of the wind blown out from the cross-flow fan 120 passing through the heat dissipation channel can be reduced, so that the wind blown out from the cross-flow fan 120 can pass through the heat dissipation channel smoothly, and the contact area with the first fin 134d and the second fin 134e is increased, thereby improving the heat dissipation effect.

[0163] See also Figure 2 and Fig.11 In some embodiments, the cooking device 100 further includes a wind shield 140, which is disposed in the shell 110 and between the component assembly 130 and the second air outlet 112 to change the direction of the airflow entering the shell 110 from the second air outlet 112 or to change the direction of the airflow flowing out of the second air outlet 112 to the outside of the shell 110.

[0164] In the first air outlet 111 and the second air outlet 112, the cross-flow fan 120 is arranged closer to the first air outlet 111, and the second air outlet 112 is arranged away from the cross-flow fan 120, and is arranged between the component assembly 130 and the second air outlet 112. When the airflow passes through the wind shield 140, due to the blocking effect of the wind shield 140, the airflow will change direction, thereby increasing the flow path of the airflow between the first air outlet 111 and the second air outlet 112, so that more airflow can flow to the component assembly 130, thereby improving the heat dissipation efficiency of the component assembly 130.

[0165] Among them, the wind shield 140 is arranged between the component assembly 130 and the second air outlet 112. It can be arranged close to the second air outlet 112, close to the component assembly 130, or in the middle position between the component assembly 130 and the second air outlet 112. In addition, the wind shield 140 can be spaced apart from the second air outlet 112, or can be directly arranged at the second air outlet 112, so as to ensure that the wind shield 140 is arranged between the component assembly 130 and the second air outlet 112.

[0166] The wind shield 140 is mainly used to provide a certain shielding effect on the airflow path between the first air outlet 111 and the second air outlet 112. When the airflow flows between the first air outlet 111 and the second air outlet 112, the airflow can have different flow directions in the shell 110, thereby increasing the flow time between the first air outlet 111 and the second air outlet 112, increasing the contact area between the airflow and the component assembly 130, and improving the heat dissipation effect on the component assembly 130.

[0167] In some embodiments, the wind shield 140 is disposed on the bottom wall of the housing 110 , and the component assembly 130 is spaced apart from the bottom wall of the housing 110 .

[0168] In order to facilitate the component assembly 130 to heat the food to be heated, most of the component assembly 130 are arranged close to the top wall of the shell 110, and have a certain gap with the bottom wall of the shell 110. Under the action of the cross-flow fan 120, the wind in the shell 110 flows between the first air outlet 111 and the second air outlet 112. There is a certain gap between the component assembly 130 and the bottom wall of the shell 110. When the wind in the gap flows to the second air outlet 112, it will not flow out directly from the second air outlet 112. Under the obstruction of the wind shield 140, it will flow to the top of the shell 110 and flow to the component assembly 130. After heat exchange with the component assembly 130, it will flow out from the second air outlet 112, thereby reducing the possibility that the wind in the shell 110 is directly blown out from the second air outlet 112 without exchanging heat with the component assembly 130.

[0169] Of course, the above is the cooling mode of the cross flow fan 120. Fig.12 As shown in the figure, the arrows indicate the airflow mode. If the air suction cooling mode is adopted, Fig.13 As shown in the figure, the arrow indicates the direction of airflow. Under the action of the cross-flow fan 120, the external wind enters the interior of the shell 110 from the second air port 112. Under the obstruction of the wind shield 140, the wind will not directly enter the gap between the component assembly 130 and the bottom wall of the shell 110, but will first flow to the component assembly 130, exchange heat with the component assembly 130, and then flow out from the second air port 112, and then flow to the first air port 111, thereby reducing the possibility that the wind entering the shell 110 from the second air port 112 does not exchange heat with the component assembly 130, and directly flows from the gap between the component assembly 130 and the bottom wall of the shell 110 to the first air port 111.

[0170] Under the action of the wind shield 140 , the wind at the second air outlet 112 tends to rise, and the upward wind will further drive the air flow around the component assembly 130 to achieve a better heat dissipation effect.

[0171] In some embodiments, the second air outlet 112 is disposed on a side wall of the housing 110 , and projections of the wind shield 140 and the second air outlet 112 on the same side wall of the housing 110 partially overlap.

[0172] The first air outlet 111 and the second air outlet 112 are respectively arranged on two opposite side walls of the shell 110. Under the action of the cross-flow fan 120, the wind in the shell 110 can flow between the first air outlet 111 and the second air outlet 112, thereby increasing the flow path of the wind in the shell 110, that is, increasing the flow time of the wind in the shell 110, which can increase the contact time with the component assembly 130 and improve the heat dissipation effect on the component assembly 130.

[0173] If the projections of the wind shield 140 and the second air outlet 112 on the same side wall of the shell 110 partially overlap, it means that the wind shield 140 can partially block the second air outlet 112, that is, the wind shield 140 can partially block the bottom of the second air outlet 112, avoiding the wind from directly flowing to the second air outlet 112 from the gap between the shell 110 and the component assembly 130, or avoiding the wind entering the shell 110 from the second air outlet 112 to directly flow to the gap between the component assembly 130 and the bottom wall of the shell 110, thereby increasing the flow time between the first air outlet 111 and the second air outlet 112, increasing the contact area between the airflow and the component assembly 130, and improving the heat dissipation effect on the component assembly 130.

[0174] In some embodiments, wind shield 140 extends along the axis of crossflow blower 120 .

[0175] The heating element 132 and the electronic control component 134 are arranged in the axial direction of the cross-flow fan 120, so that the wind blown by the cross-flow fan 120 can directly blow onto the electronic control component 134 and the heating element 132, and the wind blown by the cross-flow fan 120 can directly take away the heat from the electronic control component 134 or the heating element 132, thereby improving the heat dissipation efficiency of the heating element 132 and the electronic control component 134.

[0176] Among them, the wind shield 140 also extends along the axial direction of the cross-flow fan 120, that is, the wind shield 140 is arranged between the heating element 132 and the second air outlet 112, and between the electronic control component 134 and the second air outlet 112. There is a certain gap between the electronic control component 134 and the heating element 132 and the bottom wall of the shell 110. The wind shield 140 can block the wind at the second air outlet 112 to a certain extent, so that the wind can flow upward and flow around the heating element 132 and the electronic control component 134, thereby increasing the contact time and contact area with the heating element 132 and the electronic control component 134, and improving the heat dissipation effect of the heating element 132 and the electronic control component 134.

[0177] In some embodiments, the height of the wind shield 140 is different at at least two locations along the axial direction of the cross flow blower 120 .

[0178] Since the thickness of the electric control component 134 and the heating element 132 are different, that is, the spacing between the heating element 132 and the electric control component 134 and the bottom wall of the housing 110 is different, the height requirements of the windshield 140 are also different. Taking the heating element 132 as an example, if the spacing between the heating element 132 and the bottom wall of the housing 110 is large, the windshield 140 also needs to be set higher, so that the wind in the gap between the heating element 132 and the bottom wall of the housing 110 can be directed to the electric control component 134. If the spacing between the heating element 132 and the bottom wall of the housing 110 is small, the windshield 140 can be set shorter.

[0179] In addition, the height of the corresponding wind shield 140 can be adjusted according to the heat dissipation requirements of the heating element 132. For example, the corresponding wind shield 140 can be set higher in places where the heat of the heating element 132 is higher, so that more wind can be diverted to the heating element 132.

[0180] In some embodiments, the wind shield plate 140 includes a first wind shield section 142 and a second wind shield section 144. The first wind shield section 142 is arranged between the heat generating element 132 and the second air outlet 112, and the second wind shield section 144 is arranged between the electronic control component 134 and the second air outlet 112. The height of one end of the first wind shield section 142 close to the second wind shield section 144 is less than the height of one end of the first wind shield section 142 away from the second wind shield section 144.

[0181] Since the heat dissipation requirements at different locations of the heat generating element 132 are different, the temperature rise at the side away from the electronic control component 134 is the highest in all areas of the heat generating element 132, and the heat dissipation requirement is greater, so more wind is needed to dissipate the heat of the heat generating element 132 at that location. The height of the corresponding wind shield 140 at that location can be set higher, so that the wind in the gap can be diverted, so that more wind can flow accurately to that location of the heat generating element 132, so that the heat generating element 132 can dissipate heat quickly.

[0182] Correspondingly, the height of the end of the first windshield section 142 close to the second windshield section 144 is less than the height of the first windshield end away from the second windshield section 144. Specifically, the height of the first windshield section 142 may gradually increase in the direction from the second windshield section 144 to the first windshield section 142, or the entire first windshield section 142 may be in a stepped shape. It is sufficient that the height of the end of the first windshield section close to the second windshield section 144 is less than the height of the first windshield end away from the second windshield section 144.

[0183] In some embodiments, the heating element 132 is spaced apart from the bottom wall of the shell 110, the gap between the heating element 132 and the bottom wall of the shell 110 is a first spacing height H1, and the height of the wind shield 140 is a second spacing height H2; wherein the first spacing height H1 is greater than the second spacing height H2.

[0184] If the first spacing height H1 is greater than the second spacing height H2, it means that there is a certain gap between the projections of the heating element 132 and the wind shield 140 on the side wall of the shell 110, that is, there is a certain gap between the heating element 132 and the wind shield 140 in the height direction of the shell 110. While the wind can flow to the heating element 132, it can also flow to the second air outlet 112, so that the wind after heat exchange can flow out of the second air outlet 112 in time, thereby improving the heat exchange efficiency.

[0185] See also Figure 2 and Fig.14 In some embodiments, the cooking device 100 further includes: an air guide member 150, which is disposed between the cross-flow fan 120 and the component assembly 130, and has an air guide channel 151, wherein the opening area of ​​the air guide channel 151 gradually decreases in the direction away from the cross-flow fan 120 to change the air outlet direction of the cross-flow fan 120.

[0186] Since the crossflow fan 120 is radially discharged, under the centrifugal force of the crossflow fan 120, the wind flows out along the radial direction of the crossflow fan 120, and the outflowing wind will tend to be upward or downward, and the upward or downward wind will collide with the component assembly 130, and only a small amount of wind can enter the interior of the component assembly 130 to dissipate heat for the component assembly 130. At the same time, since the wind blown out by the crossflow fan 120 collides with the component assembly 130, a certain amount of noise will be generated, resulting in a large noise when the cooking device 100 is working.

[0187] It should be noted that the crossflow fan 120 has two rotation modes: forward rotation and reverse rotation. For the convenience of description, it is defined that when the crossflow fan 120 is in forward rotation, the wind blown out from the crossflow outlet 125 of the crossflow fan 120 has an upward trend. On the contrary, when the crossflow fan 120 is reversed, the wind blown out from the crossflow outlet 125 of the crossflow fan 120 has a downward trend. For the convenience of description, in this application, the wind outlet of the crossflow fan 120 is described as having an upward trend. When the wind blown out by the crossflow fan 120 has a downward trend, it can be deduced by analogy.

[0188] In the embodiment of the present application, an air guide 150 is provided between the crossflow fan 120 and the component assembly 130. When the crossflow fan 120 blows out air toward the component assembly 130, it will first pass through the air guide 150. In the direction away from the crossflow fan 120, the opening area of ​​the air guide channel 151 gradually decreases, which means that at least one surface of the air guide channel 151 is arranged close to each other. Whether the air outlet direction of the crossflow fan 120 has an upward or downward trend, the air guide channel 151 can change the air outlet direction of the crossflow fan 120 to a certain extent, weaken the upward or downward trend of the air outlet direction, so that the air blown out by the crossflow fan 120 can enter the interior of the component assembly 130, and improve the heat dissipation effect on the component assembly 130. At the same time, since the upward or downward trend of the air blown out by the crossflow fan 120 is weakened, it can pass through the component assembly 130 with less resistance, reducing the noise generated by the collision with the component assembly 130.

[0189] The air guide 150 is disposed between the crossflow fan 120 and the component assembly 130. The air guide 150 may be connected to the crossflow fan 120, or connected to the component assembly 130, or installed on the housing 110 and connected to the housing 110. The connection relationship of the air guide 150 may not be specifically limited, and it is sufficient to ensure that the air guide 150 is located between the crossflow fan 120 and the component assembly 130.

[0190] See also Fig.14 and Fig.15 In some embodiments, the crossflow fan 120 includes a fan body 121, a fan support 122, a volute tongue 123 and a volute 124, the fan body 121 is mounted on the fan support 122, the volute 124 and the volute tongue 123 are connected to the fan support 122, and the volute 124 and the volute tongue 123 form a crossflow outlet 125;

[0191] The air guide 150 is disposed at the cross-flow air outlet 125 and is connected to at least one of the fan support 122 , the volute tongue 123 and the volute casing 124 .

[0192] Among them, the air guide member 150 is connected to at least one of the fan bracket 122, the volute tongue 123 and the volute casing 124, and can be connected to any one of the fan bracket 122, the volute tongue 123 and the volute casing 124, or connected to any two of the fan bracket 122, the volute casing 124 and the volute tongue 123, or connected to all three of the fan bracket 122, the volute casing 124 and the volute tongue 123.

[0193] In some embodiments, a windshield 152 is provided on one side of the crossflow air outlet 125 close to the volute tongue 123, and the windshield 152 is tilted toward the direction close to the volute 124. That is, the windshield 152 is tilted downward. Since the centrifugal force generated by the crossflow fan 120 at different rotation speeds is different, resulting in different wind speeds, in order to ensure that the windshield 152 can play a role in changing the direction of the wind at different rotation speeds, the windshield 152 can be tilted downward, so that the wind blown out from the crossflow fan 120 can be directed downward, so that the wind can pass through the component assembly 130 as parallel as possible, which can reduce the collision with the component assembly 130 and reduce the noise of the cooking device 100 during operation.

[0194] In addition, the wind can pass through the component assembly 130 as parallel as possible, reducing the collision with the component assembly 130 while also reducing the resistance of the wind passing through the component assembly 130, allowing more wind to flow into the interior of the component assembly 130, improving the heat exchange efficiency with the component assembly 130 and improving the heat dissipation effect.

[0195] The volute tongue 123 is arranged in the direction of the volute 124, and the windshield surface 152 is arranged on the side of the crossflow outlet 125 close to the volute tongue 123, which means that the windshield surface 152 is arranged above the crossflow outlet 125. Since the outlet direction of the crossflow fan 120 has an upward trend, the windshield surface 152 is arranged above the crossflow outlet 125. In the upward direction, the windshield surface 152 can play a certain blocking role on the wind blown out from the crossflow fan 120, so that the wind blown out from the crossflow fan 120 can weaken the upward trend after passing through the windshield surface 152, weaken the upward trend of the outlet direction, and allow the wind blown out of the crossflow fan 120 to enter the interior of the component assembly 130, thereby improving the heat dissipation effect on the component assembly 130. At the same time, since the upward or downward trend of the wind blown out by the crossflow fan 120 is weakened, it can pass through the component assembly 130 with less resistance, thereby reducing the noise generated by the collision with the component assembly 130.

[0196] It should be noted that the wind shielding surface 152 is arranged on one side of the through-flow outlet 125 close to the volute tongue 123 , and may be arranged in the area of ​​the through-flow outlet 125 , may be arranged at the edge of the through-flow outlet 125 , or may be arranged above the through-flow outlet 125 .

[0197] In some embodiments, the inclination angle α of the windshield surface 152 is less than 90 degrees. Since the windshield surface 152 is tilted downward, the inclination angle of the windshield surface 152 can also be considered as the angle between the windshield surface 152 and the plane of the volute tongue 123. The larger the inclination angle of the windshield surface 152, the closer the windshield surface 152 is to a vertical state. If the inclination angle of the windshield surface 152 is less than 90 degrees, it means that the windshield surface 152 can be at any angle between the horizontal plane and the vertical plane.

[0198] The inclination angle of the wind shield surface 152 is less than 90 degrees. After the wind blown out from the cross-flow fan 120 hits the wind shield surface 152, since the wind shield surface 152 is inclined downward, the wind flows downward along the extension direction of the wind shield surface 152, so that the wind can flow downward, thereby changing the outlet direction of the wind blown out from the cross-flow fan 120, reducing the situation where the wind is directly blown upward and cannot contact the component assembly 130 or collides with the top of the component assembly 130, and can also increase the contact area between the component assembly 130 and the heat exchange efficiency.

[0199] If the wind blown out of the crossflow fan 120 does not change direction through the wind shield 152, it will collide with the heat dissipation body 134c of the radiator 134b, increasing the resistance of the wind flowing through the heat dissipation channel, so that the wind cannot smoothly flow through the heat dissipation channel of the radiator 134b. After the wind guide 150 is provided, the wind shield 152 can guide the wind blown toward the radiator 134b by the crossflow fan 120 to a certain extent, and can suppress the upward trend of the wind from the crossflow fan 120, so that the wind can pass through the heat dissipation channel of the radiator 134b in parallel with less resistance, and can increase the heat exchange area between the wind from the crossflow fan 120 and the heat dissipation fins, thereby improving the heat dissipation effect.

[0200] In addition, in some other embodiments, the windshield 152 and the crossflow fan 120 have different wind outlet directions. In order to enable the windshield 152 to change the wind outlet direction of the crossflow fan 120, the angle between the windshield 152 and the bottom wall of the shell 110 is smaller than the angle between the wind outlet direction of the crossflow fan 120 and the bottom wall of the shell 110. For example: under the condition that the wind outlet direction is upward, the angle between the wind outlet direction and the shell 110 is 45 degrees, then the angle between the windshield 152 and the shell 110 is less than 45 degrees. At this time, the windshield 152 can also show an upward trend, and the angle between the windshield 152 and the bottom wall of the shell 110 is less than 45 degrees. In other words, in the embodiment of the present application, the windshield 152 and the wind outlet direction of the crossflow fan 120 are set at an angle, and it is necessary to ensure that the windshield 152 can change the wind outlet direction of the crossflow fan 120.

[0201] In some embodiments, the side of the air guide channel 151 close to the volute 124 has an air guide surface 154, and the distance between the air guide surface 154 and the wind shielding surface 152 forms an air guide channel 151 connected to the through-flow air outlet 125; the angle β between the air guide surface 154 and the volute 124 is less than 90 degrees.

[0202] The air guide member 150 has an air guide surface 154 on one side close to the volute 124, which means that the air guide surface 154 is arranged below the through-flow outlet 125, and the shape of the volute 124 is adapted to the shape of the fan body 121, so the volute 124 is also roughly circular, and the angle between the air guide surface 154 and the volute 124 refers to the angle between the tangents of the connection between the air guide surface 154 and the volute 124.

[0203] The heating element 132 is disposed near the top wall of the housing 110, and the air guide surface 154 is disposed below the crossflow outlet 125. The upper portion of the heating element 132 is mainly used to heat the heated object, and other components 130 may be disposed below the heating element 132. If the temperature below the heating element 132 is too high, it will also affect the operation of other components 130. If no other components 130 are disposed below the heating element 132, the excessively high temperature below the heating element 132 will cause the temperature at the bottom of the housing 110 to be too high, and will also affect other structures.

[0204] The angle between the wind guide surface 154 and the volute 124 is less than 90 degrees, which can make the wind below the cross-flow outlet 125 have a gentler wind outlet direction, so that the wind below the cross-flow outlet 125 can blow to the lower surface of the heating element 132 and dissipate the heat from the lower surface of the heating element 132.

[0205] It should be noted that the electronic control component 134 and the heating element 132 are respectively located at different positions in the shell 110. The electronic control component 134 and the heating element 132 can be arranged in the extension direction of the air guide channel 151, so that the wind blown by the cross-flow fan 120 can dissipate heat for the electronic control component 134 and the heating element 132 at the same time.

[0206] In some embodiments, the air guide 150 is detachably disposed at the cross-flow air outlet 125. The air guide 150 is disposed at the cross-flow air outlet 125 so that the air guide channel 151 can be directly connected to the cross-flow air outlet 125, that is, the entire air guide 150 is directly covered on the cross-flow air outlet 125, and the wind blown out from the cross-flow air outlet 125 can directly enter the air guide channel 151, and be guided to the component assembly 130 through the air guide channel 151.

[0207] The air guide member 150 is detachably connected to the housing 110 , which can facilitate installation and maintenance of the air guide member 150 .

[0208] See also Fig.16 In some embodiments, the air guide member 150 includes an air guide portion 156 and a first overlapping portion 157 connected to the air guide portion 156 , the air guide channel 151 is disposed in the air guide portion 156 , the first overlapping portion 157 overlaps the volute tongue 123 , and is detachably connected to the volute tongue 123 .

[0209] The first overlap portion 157 is arranged above the air guide portion 156. When the air guide member 150 is installed, the first overlap portion 157 is overlapped on the volute tongue 123, and the first overlap portion 157 and the volute tongue 123 are detachably connected by a fixing member. In addition, the first overlap portion 157 can also be arranged below the air guide portion 156 and detachably connected to the volute 124.

[0210] In some embodiments, the air guide member 150 includes an air guide portion 156 and a second overlapping portion 158 connected to the air guide portion 156, the air guide channel 151 is arranged in the air guide portion 156, the wind shielding surface 152 is arranged in the air guide channel 151, and the second overlapping portion 158 is overlapped with the fan bracket 122 and is detachably connected to the fan bracket 122.

[0211] The second overlap portion 158 is disposed on the side of the air guide portion 156. When the air guide member 150 is installed, the second overlap portion 158 is overlapped on the fan bracket 122, and the second overlap portion 158 and the fan bracket 122 are detachably connected by a fixing member.

[0212] It should be noted that the air guide 150 may be provided with both the first overlap portion 157 and the second overlap portion 158, or only one of them, that is, only the first overlap portion 157 or only the second overlap portion 158. When the first overlap portion 157 and the second overlap portion 158 are provided at the same time, the first overlap portion 157 is provided above and below the air guide portion 156, and the second overlap portion 158 is provided at the side of the air guide portion 156.

[0213] In some embodiments, the air guide 150 is disposed between the electronic control assembly 134 and the crossflow blower 120 .

[0214] The heating element 132 and the electronic control component 134 are arranged in the axial direction of the cross-flow fan 120, so that the wind blown by the cross-flow fan 120 can directly blow onto the electronic control component 134 and the heating element 132, and the wind blown by the cross-flow fan 120 can directly take away the heat from the electronic control component 134 or the heating element 132, thereby improving the heat dissipation efficiency of the heating element 132 and the electronic control component 134.

[0215] The circuit board 134a generates heat during operation. If the heat is not dissipated in time, the electronic components on the circuit board 134a will be damaged. The circuit board 134a needs to be dissipated in time. If the wind blown out of the cross-flow fan 120 does not change direction through the wind shield 152, it will collide with the heat dissipation body 134c of the radiator 134b, increasing the resistance of the wind flowing through the heat dissipation channel, so that the wind cannot smoothly flow through the heat dissipation channel of the radiator 134b. The heating element 132 is originally used to heat the heated object by generating heat, and there is no need for the wind to enter its interior when dissipating heat. Therefore, the radiator 134b needs to be provided with an air guide 150, and the air guide 150 can be provided only between the cross-flow fan 120 and the electronic control component 134.

[0216] After the wind guide member 150 is set, the wind shielding surface 152 can guide the wind blown by the cross-flow fan 120 toward the radiator 134b to a certain extent, thereby suppressing the upward trend of the wind outlet of the cross-flow fan 120, allowing the wind to pass through the heat dissipation channel of the radiator 134b in parallel with smaller resistance, thereby increasing the heat exchange area between the air outlet of the cross-flow fan 120 and the heat dissipation fins, thereby improving the heat dissipation effect.

[0217] In some embodiments, in the axial direction of the cross-flow blower 120 , the length of the air guide 150 is greater than or equal to the length of the electronic control component 134 .

[0218] Since the electronic control component 134 and the heating element 132 are arranged in the circumferential direction of the cross-flow fan 120, in order to improve the heat dissipation effect on the radiator 134b, the length of the air guide 150 is made greater than or equal to the length of the electronic control component 134, so that every part of the electronic control component 134 can be blown by the wind blown by the cross-flow fan 120, and the radiator 134b can be cooled in time, thereby reducing the heat accumulation on the radiator 134b and improving the heat dissipation effect of the radiator 134b.

[0219] In addition, in some other embodiments, the air guide member 150 may also be disposed between the electronic control component 134 and the cross-flow fan 120 , and between the heating element 132 and the cross-flow fan 120 .

[0220] See also Fig.17 and Fig.18 In some embodiments, the cross-flow fan 120 includes a fan body 121, a fan bracket 122 and a vibration damper 126, the fan body 121 is installed on the fan bracket 122, the fan bracket 122 is fixed to the housing 110 through the vibration damper 126, and\or, the vibration damper 126 connects the fan body 121 and the fan bracket 122.

[0221] The fan body 121 is mounted on the fan bracket 122, and the fan bracket 122 is fixed on the housing 110. During the rotation of the fan body 121, the fan body 121 and the fan bracket 122 are prone to collision, abnormal sound, and thus noise. Similarly, due to the relative displacement between the fan bracket 122 and the housing 110 caused by the rotation of the fan body 121, collision, abnormal sound, and thus noise are also prone to occur. In the embodiment of the present application, a vibration damping member 126 is provided to buffer the collision between the fan body 121 and the fan bracket 122 and / or buffer the collision between the fan bracket 122 and the housing 110, thereby reducing the noise generated by the collision of the components of the cross-flow fan 120 during movement, and reducing the noise of the cooking device 100 during operation.

[0222] The fan bracket 122 is fixed to the housing 110 through the vibration damping member 126, and / or the vibration damping member 126 connects the fan body 121 and the fan bracket 122. The vibration damping member 126 may be arranged only between the fan body 121 and the fan bracket 122, or only between the fan bracket 122 and the housing 110, or the vibration damping member 126 may be arranged between the fan body 121 and the fan bracket 122, and between the fan bracket 122 and the housing 110 at the same time.

[0223] In some embodiments, the vibration damping member 126 includes at least one of a vibration damping bracket 127, a vibration damping portion 128, and a vibration damping seat 129. The vibration damping bracket 127 is fixedly connected to the shell 110, and the fan bracket 122 is installed on the vibration damping bracket 127. The vibration damping portion 128 and the vibration damping seat 129 cooperate with the fan body 121 and are connected to the fan bracket 122.

[0224] The cross-flow fan 120 is roughly in the shape of a long strip, and two fan brackets 122 are provided. The two fan brackets 122 are respectively arranged at the two ends of the fan body 121, that is, the two ends of the fan body 121 are fixedly connected to the shell 110 through the two fan brackets 122. Correspondingly, two vibration-damping brackets 127 are also provided, and the vibration-damping brackets 127 are arranged one-to-one with the fan brackets 122.

[0225] Among them, the vibration-damping bracket 127, the vibration-damping part 128 and the vibration-damping seat 129 all have a certain elasticity. During the operation of the cross-flow fan 120, if displacement occurs between the fan body 121 and the fan bracket 122, the fan body 121 will squeeze the vibration-damping part 128 or the vibration-damping seat 129 to deform the vibration-damping seat 129. The fan body 121 will not directly contact the fan bracket 122, thereby avoiding collision between the fan body 121 and the fan bracket 122 and reducing the noise generated by the collision between the fan body 121 and the fan.

[0226] Similarly, if displacement occurs between the fan bracket 122 and the shell 110, the fan bracket 122 will squeeze the vibration-damping bracket 127, causing the vibration-damping bracket 127 to deform. The fan bracket 122 will not directly contact the shell 110, thereby avoiding direct collision between the fan bracket 122 and the shell 110 and reducing the noise generated by the collision between the fan bracket 122 and the shell 110.

[0227] The vibration damping member 126 includes at least one of the vibration damping bracket 127, the vibration damping part 128 and the vibration damping seat 129, which means that the vibration damping member 126 may include only any one of the vibration damping bracket 127, the vibration damping part 128 and the vibration damping seat 129, or only any two of the vibration damping bracket 127, the vibration damping part 128 and the vibration damping seat 129, or may include the vibration damping bracket 127, the vibration damping part 128 and the vibration damping seat 129 at the same time. The following will respectively describe in detail how the vibration damping bracket 127 connects the fan bracket 122 and the housing 110, and how the vibration damping part 128 and the vibration damping seat 129 connect the fan body 121 and the fan bracket 122. When the vibration damping member 126 includes two or all three of them at the same time, the three situations can be combined. First, the specific structure of the vibration damping bracket 127 and how to connect the fan bracket 122 and the housing 110 are introduced.

[0228] See also Fig.19 In some embodiments, the vibration reduction bracket 127 includes a vibration reduction body 127a and a fixing base 127b connected to the vibration reduction body 127a, the fixing base 127b is connected to the housing 110, the vibration reduction body 127a has a fixing groove 127c, and the fan bracket 122 is fixed in the fixing groove 127c.

[0229] The vibration reduction body 127a is connected to the fan bracket 122, and the fixing seat 127b is fixedly connected to the housing 110. Since the fan body 121 is in a long strip shape, the fixing seat 127b and the vibration reduction body 127a are arranged at an angle. The fixing seat 127b can be arranged horizontally to fit the bottom wall of the housing 110, and the vibration reduction body 127a can be arranged roughly vertically.

[0230] The fan bracket 122 is fixed in the fixing groove 127c, and the fixing groove 127c can fix the fan bracket 122 and separate the fan bracket 122 from the shell 110 to avoid direct contact between the fan bracket 122 and the shell 110, thereby reducing the possibility of collision between the fan bracket 122 and the shell 110.

[0231] As for the fixing method between the fixing base 127b and the housing 110, the fixing base 127b and the housing 110 can be fixed by screws. The fixing base 127b and the housing 110 can also be connected by a clamping method.

[0232] In some embodiments, at least one vibration-damping protrusion 127 d is disposed around the outer wall of the vibration-damping body 127 a , and the vibration-damping protrusion 127 d is in contact with the inner wall of the housing 110 .

[0233] The vibration-damping protrusion 127d is arranged on the outer wall of the vibration-damping body 127a, that is, the vibration-damping protrusion 127d is arranged outside the fixing groove 127c, and the vibration-damping protrusion 127d contacts the inner wall of the shell 110. When there is a relative displacement between the fan bracket 122 and the shell 110, the fan bracket 122 will squeeze the inner wall of the fixing groove 127c, causing the vibration-damping protrusion 127d to deform, thereby avoiding collision between the fan bracket 122 and the shell 110 and generating noise.

[0234] By making the vibration-damping protrusion 127d contact with the shell 110, the direct contact area with the shell 110 can be reduced, and the surface contact can be changed into line contact or point contact. When there is a relative displacement between the fan bracket 122 and the shell 110, the transmitted vibration energy is also smaller than that of the surface contact, and the vibration-damping protrusion 127d can also be deformed quickly, thereby achieving the purpose of rapid buffering.

[0235] At least one vibration-damping protrusion 127d is provided on the outer wall of the vibration-damping body 127a. The vibration-damping protrusion 127d may be one or more. If there are more than one vibration-damping protrusion 127d, the multiple vibration-damping protrusions 127d are arranged at intervals on the outer wall of the vibration-damping body 127a. The number of vibration-damping protrusions 127d may be set according to the length of the vibration-damping body 127a in the axial direction of the cross-flow blower 120. The longer the length of the vibration-damping body 127a is, the more vibration-damping protrusions 127d may be set.

[0236] As for the height of the vibration-damping protrusion 127d, it can be set according to the vibration-damping amount required by the entire vibration-damping bracket 127. If the required vibration-damping amount is greater, the height of the vibration-damping protrusion 127d can be set higher; if the required vibration-damping amount is smaller, the height of the vibration-damping protrusion 127d can be set smaller.

[0237] In some embodiments, the vibration-damping body 127a and the fixing seat 127b are integrally formed. When producing the entire vibration-damping member 126, there is no need to set up multiple molds and multiple production processes, which can reduce manufacturing costs. At the same time, the integral formation of the vibration-damping body 127a and the fixing seat 127b can also reduce the assembly process and reduce the problem of falling off or instability caused by assembly.

[0238] The entire vibration damper 126 is made of an elastic structure, and can be made of a silicone material or a rubber material. Currently, it can also be made of other materials as long as the vibration damper 126 has a certain elasticity.

[0239] The above is the structure and vibration reduction method of the vibration reduction member 126, and the structure and vibration reduction method of the vibration reduction part 128 will be introduced below.

[0240] See also Fig. 20 and Fig.21 In some embodiments, the fan body 121 includes a wind wheel 121a, a fan shaft 121b and a motor 121c. The motor 121c and the wind wheel 121a are respectively arranged on both sides of the fan bracket 122. The fan bracket 122 has a mounting hole 122a, the vibration reduction part 128 has a connecting hole 128a, and the fan shaft 121b is passed through the mounting hole 122a and the connecting hole 128a.

[0241] The motor 121c and the wind wheel 121a are respectively arranged on both sides of the fan bracket 122, that is, the fan shaft 121b is fixed on the fan bracket 122, and the motor 121c drives the wind wheel 121a to rotate through the fan shaft 121b. In order to facilitate the installation of the fan shaft 121b, a mounting hole 122a is set on the fan bracket 122, and a connecting hole 128a is set on the vibration reduction part 128 to arrange the fan shaft 121b.

[0242] Of course, in order for the fan shaft 121b to pass through smoothly and work normally, the diameter of the mounting hole 122a should be larger than the diameter of the fan shaft 121b, and similarly the diameter of the connecting hole 128a should also be larger than the diameter of the fan shaft 121b.

[0243] In some embodiments, the vibration reduction unit 128 is disposed between the motor 121c and the fan bracket 122. There is a certain distance between the wind wheel 121a and the fan bracket 122, so the possibility of collision between the wind wheel 121a and the fan bracket 122 is very small, and the distance between the motor 121c and the fan bracket 122 is relatively close. In the process of driving the wind wheel 121a to rotate, it is easy to collide with the fan bracket 122 during the rotation process. The vibration reduction unit 128 is disposed between the motor 121c and the fan bracket 122 to avoid direct contact between the motor 121c and the fan bracket 122, thereby reducing the noise caused by the collision between the fan bracket 122 and the motor 121c.

[0244] In some embodiments, the vibration reduction part 128 is in sheet form, and the vibration reduction part 128 is attached to the fan bracket 122. The vibration reduction part 128 is in sheet form, that is, the vibration reduction part 128 is arranged within the contact range between the fan bracket 122 and the motor 121c, so as to avoid partial contact between the fan bracket 122 and the motor 121c due to offset, etc., and collision noise.

[0245] Please refer to Fig. 20 , Fig.21 and Fig. 22In some embodiments, the motor 121c has a first fixing hole 121d, the vibration reduction portion 128 has a second fixing hole 128b, and the fan bracket 122 has a third fixing hole 122b. The cooking device 100 also includes a fixing member, which is passed through the first fixing hole 121d, the second fixing hole 128b and the third fixing hole 122b.

[0246] In order to minimize the displacement between the motor 121c and the fan bracket 122, the motor 121c can be directly fixed to the fan bracket 122. Specifically, the motor 121c is fixed to the fan bracket 122 by passing a fixing member through the first fixing hole 121d, the second fixing hole 128b and the third fixing hole 122b.

[0247] Similarly, the entire vibration-damping portion 128 is made of an elastic structure, and may be made of a silicone material or a rubber material. Currently, it may also be made of other materials as long as the vibration-damping portion 128 has a certain elasticity.

[0248] The above is the specific structure and vibration reduction method of the vibration reduction part 128, and the specific structure and vibration reduction method of the vibration reduction seat 129 will be introduced below.

[0249] See also Fig.18 and Fig.23 In some embodiments, the fan body 121 includes a fan wheel 121a, a fan shaft 121b and a bearing 121e, the fan wheel 121a is sleeved on the fan shaft 121b, the bearing 121e is connected to one end of the fan shaft 121b, the vibration damping seat 129 has a receiving hole 129a, and the bearing 121e is disposed in the receiving hole 129a;

[0250] The fan bracket 122 has a mounting hole 122a, and the vibration reduction seat 129 has a positioning slot 129b. The vibration reduction seat 129 penetrates the mounting hole 122a, and the inner wall of the mounting hole 122a is clamped in the positioning slot 129b.

[0251] It is easy to understand that the bearing 121e and the motor 121c are respectively arranged at the two ends of the fan shaft 121b, that is, one end of the fan shaft 121b is connected to the motor 121c, and the other end is fixed to the fan bracket 122 through the bearing 121e. Similarly, during the movement, the fan body 121 may be displaced along the axial direction. The bearing 121e is connected to the fan bracket 122 through the bearing 121e seat, which can avoid direct contact between the bearing 121e and the fan bracket 122, thereby reducing the noise caused by collision.

[0252] Specifically, the entire vibration damping seat 129 is passed through the mounting hole 122a, and the mounting hole 122a is clamped in the positioning slot 129b, that is, the fan bracket 122 around the mounting hole 122a is clamped in the positioning slot 129b. When the entire cross-flow fan 120 has axial or radial displacement, the fan bracket 122 will resist the inner wall of the positioning slot 129b, causing the vibration damping seat 129 to deform, thereby buffering the displacement between the bearing 121e and the fan bracket 122, and making the fan bracket 122 and the bearing 121e in flexible contact.

[0253] In some embodiments, the positioning slot 129 b is disposed on the outer surface of the vibration damping seat 129 .

[0254] Among them, the vibration damping seat 129 is roughly cylindrical, the bearing 121e hole is set on one end face of the vibration damping seat 129, and the positioning groove 129b is arranged on the circumferential surface of the vibration damping seat 129. By arranging the bearing 121e hole and the positioning groove 129b on the end face and the circumferential surface, the layout of the vibration damping seat 129 can be reasonably utilized, thereby reducing the volume of the vibration damping seat 129.

[0255] In some embodiments, at least one inner wall of the positioning slot 129 b is provided with a plurality of elastic portions 129 c , and the plurality of elastic portions 129 c are in contact with the fan bracket 122 .

[0256] The multiple elastic parts 129c are arranged at intervals, that is, when the fan bracket 122 is clamped in the positioning slot 129b, the elastic part 129c contacts the fan bracket 122. The elastic part 129c is smaller than the inner wall surface of the entire positioning slot 129b, that is, the contact area between the elastic part 129c and the fan bracket 122 is smaller. When displacement or vibration occurs, the vibration transmission amount is also relatively small, which can achieve the effect of rapid vibration isolation.

[0257] It is easy to understand that at least one inner wall of the positioning slot 129b is provided with multiple elastic parts 129c, and only one inner wall may be provided with an elastic part 129c, or two inner walls may be provided with elastic parts 129c, or each inner wall may be provided with an elastic part 129c.

[0258] In some embodiments, a plurality of elastic portions 129c are disposed on two opposite inner walls of the positioning slot 129b, and the plurality of elastic portions 129c on the two inner walls are disposed in one-to-one correspondence.

[0259] When elastic parts 129c are provided on two inner walls opposite to the positioning slot 129b, the elastic parts 129c can be provided one-to-one so that the same position on both sides of the fan bracket 122 contacts the elastic part 129c, reducing the risk of deformation of the fan bracket 122.

[0260] The entire vibration damping seat 129 is made of an elastic structure, and can be made of a silicone material, or a rubber material, or currently can be made of other materials, as long as the vibration damping seat 129 has a certain elasticity.

[0261] In some embodiments, the hardness of the vibration reduction portion 128, the vibration reduction seat 129 and the vibration reduction bracket 127 is 40 degrees to 50 degrees.

[0262] If the hardness of the vibration damping part 128 is too large, when a collision or vibration occurs, the vibration damping part 128 will be smaller, which will cause the motor 121c and the fan bracket 122 to be close to rigid contact, which may easily damage the motor 121c. If the hardness of the vibration damping part 128 is too small, when a collision or vibration occurs, the vibration damping part 128 will be larger, and after reaching the limit position, the motor 121c and the fan bracket 122 will still be in rigid contact. Setting the hardness of the vibration damping part 128 at 40 degrees to 50 degrees can ensure as much as possible that the motor 121c and the fan bracket 122 can play a buffering role when displacement or collision occurs, avoiding direct collision damage to the motor 121c or the fan bracket 122, and can also avoid the noise generated by the collision between the two.

[0263] If the hardness of the vibration damping seat 129 is too large, when a collision or vibration occurs, the vibration damping part 128 will be smaller, which will cause the bearing 121e and the fan bracket 122 to be close to rigid contact, which may easily damage the bearing 121e. If the hardness of the vibration damping seat 129 is too small, when a collision or vibration occurs, the vibration damping seat 129 will be larger, and after reaching the limit position, the bearing 121e and the fan bracket 122 will still be in rigid contact. Setting the hardness of the vibration damping seat 129 at 40 degrees to 50 degrees can ensure as much as possible that it can play a buffering role between the bearing 121e and the fan bracket 122 when displacement or collision occurs, avoiding direct collision damage to the bearing 121e or the fan bracket 122, and also avoiding the noise generated by the collision between the two.

[0264] If the hardness of the vibration-damping bracket 127 is too large, when a collision or vibration occurs, the vibration-damping bracket 127 will be smaller, which will cause the housing 110 and the fan bracket 122 to be in close to rigid contact, which may easily damage the fan bracket 122 and the housing 110. If the hardness of the vibration-damping bracket 127 is too small, when a collision or vibration occurs, the vibration-damping bracket 127 will be larger, and after reaching the limit position, the housing 110 and the fan bracket 122 will still be in rigid contact. Setting the hardness of the vibration-damping bracket 127 to 40 degrees to 50 degrees can ensure as much as possible that the housing 110 and the fan bracket 122 can play a buffering role when displacement or collision occurs, avoiding direct collision damage to the housing 110 or the fan bracket 122, and also avoiding the noise generated by the collision between the two.

[0265] It is easy to understand that different hardnesses can be selected for the vibration reduction portion 128 , the vibration reduction seat 129 and the vibration reduction bracket 127 for different cross-flow blowers 120 and different housings 110 .

[0266] To sum up, the cooking device 100 provided in the embodiment of the present application divides the interior of the shell 110 into an independent first heat dissipation channel 113 and a second heat dissipation channel 114, so that the heat dissipation of the heating element 132 and the heat dissipation of the electronic control component 134 are independent of each other, and the wind after heat exchange with the heating element 132 is avoided as much as possible from flowing to the electronic control component 134, which can improve the heat dissipation effect of the heating element 132 and the electronic control component 134.
