Most cooking devices inevitably generate noise when running, affecting the user experience. For example, sources of noise generated during operation of an induction cooker or induction cooktop may include electromagnetic noise, fan duct noise, boiling noise. When running to mid-to-late stages, the dominant source of noise is fan duct noise. The fan and the air duct can be optimized to reduce noise of the fan air duct of the electromagnetic oven. From the angle of optimizing a fan, an axial flow fan or a centrifugal fan is used for heat dissipation in an electromagnetic oven on the market at present, the fan speed can be reduced by designing the axial flow fan with larger air quantity and better performance or using the centrifugal fan with larger air pressure to replace the axial flow fan or the centrifugal fan, but the method has the limitation that the heating element is purged and dissipated after the air outlet of the axial flow fan in the electromagnetic oven reaches the oven panel, so that the heat dissipation effect can be influenced, and the kinetic energy of part of air can be converted into noise. The cooking equipment provided by the embodiment of the application can improve the problems, and the cross-flow fan for the cooking equipment provided by the embodiment of the application can replace an axial flow fan or a centrifugal fan to improve the noise problem of the cooking equipment in the working process to a certain extent.

The axial line of the cross flow fan is longer, abnormal sound is easy to occur in the rotation process of the cross flow fan, noise is also generated, and the cooking equipment provided by the embodiment of the application can improve the problems.

The application is described below with reference to specific embodiments in conjunction with the accompanying drawings:

Referring to fig. 1 and 2, a cooking apparatus 100 is provided in an embodiment of the present application, and the cooking apparatus 100 is provided to reduce noise in the working process of the cross-flow fan 120.

The cooking device 100 may be an induction cooker or an electromagnetic oven or the like that performs cooking by electric heating.

In an embodiment of the present application, the cooking apparatus 100 includes: the shell 110, the cross flow fan 120, the heating element 132 and the electric control assembly 134 are penetrated, the cross flow fan 120 is arranged in the shell 110, and the shell 110 is provided with a first heat dissipation channel 113 and a second heat dissipation channel 114 in the axial direction of the cross flow fan 120; the heating element 132 is disposed in the first heat dissipation channel 113, and the electronic control assembly 134 is disposed in the second heat dissipation channel 114.

The casing 110 is a basic component of the cooking apparatus 100 provided by the embodiment of the present application, and can provide a mounting basis for the structures such as the heating element 132, the electric control assembly 134, the through-flow fan 120, the air guide 150, etc., the heating element 132, the electric control assembly 134, the through-flow fan 120, the air guide 150 are all mounted in the casing 110, and the casing 110 can protect the components such as the heating element 132, the electric control assembly 134, the through-flow fan 120, the air guide 150, etc., so as to reduce the damages of the structures such as the components, the through-flow fan 120, the air guide 150, etc.

The casing 110 is further provided with a first air port 111 and a second air port 112 which are both communicated with the first heat dissipation channel 113 and the second heat dissipation channel 114, wherein one of the first air port 111 and the second air port 112 can be used as an air inlet, the other one can be used as an air outlet, the first air port 111 can be used as an air inlet, the second air port 112 can be used as an air outlet, the first air port 111 can be used as an air outlet, and the second air port 112 can be used as an air inlet.

Since the cross flow fan 120 is disposed closer to the first air port 111 among the first air port 111 and the second air port 112, if the entire cooking apparatus 100 radiates heat by blowing, the first air port 111 serves as an air inlet and the second air port 112 serves as an air outlet. If the whole cooking apparatus 100 adopts the air suction mode to dissipate heat, the first air port 111 is used as an air outlet, and the second air port 112 is used as an air inlet. No matter which of the first air opening 111 and the second air opening 112 is used as the air inlet or the air outlet, air flow can be formed between the first air opening 111 and the second air opening 112 after the cross-flow fan 120 is started, and can exchange heat with the element assembly 130 through the element assembly 130, so that heat of the element assembly 130 is taken away, and heat of the element assembly 130 is dissipated.

For convenience of description, the embodiment of the present application is described by taking the heat dissipation of the whole cooking apparatus 100 by adopting the air blowing mode as an example, that is, the first air port 111 is taken as an air inlet, the second air port 112 is taken as an air outlet as an example, and the same applies when the cooking apparatus 100 dissipates heat by adopting the air suction mode.

As for the position of the cross flow fan 120, the cross flow fan 120 may be disposed at the first air port 111, so as to improve the drainage effect of the cross flow fan 120. The cross-flow fan 120 may be disposed in the housing 110 and spaced from the first air port 111 to be closer to the first air port 111.

The heating element 132 is a component for providing a heat source for the whole cooking apparatus 100, and may be a coil, where the volume of the heating element 132 is relatively larger, and under the same volume, in order to ensure that the heating power of the heating element 132 can compress the arrangement space of the electric control assembly 134 as much as possible, if the space of the electric control assembly 134 is smaller, heat accumulation is easily caused, an untimely heat dissipation situation occurs, and if the electric control assembly 134 dissipates heat untimely, a situation that the components are damaged due to too high local temperature of the electric control assembly 134 easily occurs.

Because the temperature of the heating element 132 is higher, the temperature of the air blown out from the through-flow fan 120 and the temperature of the heating element 132 after heat exchange are relatively higher, if the air after heat exchange with the heating element 132 passes through the electric control assembly 134 again, the temperature of the electric control assembly 134 cannot be reduced easily, and the temperature of the electric control assembly 134 is possibly increased, so that damage to components on the electric control assembly 134 is caused.

The cross flow fan 120 is rectangular, and the air-out face is wider, and the piece 132 that generates heat, automatically controlled subassembly 134 can arrange in the axis direction of cross flow fan 120, makes the wind that cross flow fan 120 blows out can dispel the heat to the piece 132 that generates heat, automatically controlled subassembly 134 respectively, makes the piece 132 that generates heat, automatically controlled subassembly 134 do not arrange in the air-out direction of cross flow fan 120, makes the wind that blows out from cross flow fan 120 can directly blow on the piece 132 that generates heat, automatically controlled subassembly 134 alone, can improve the radiating effect to the piece 132 that generates heat, automatically controlled subassembly 134.

In the axial direction of the cross-flow fan 120, the inner space of the housing 110 is provided with a first heat dissipation channel 113 and a second heat dissipation channel 114 which are arranged in the axial direction of the cross-flow fan 120, the heating element 132 is arranged in the first heat dissipation channel 113, the electric 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, because the axial direction of the cross-flow fan 120 is relatively long, wind blown from the cross-flow fan 120 can directly enter the first heat dissipation channel 113 and the second heat dissipation channel 114, that is, wind blown from the cross-flow fan 120 directly enters the first heat dissipation channel 113 and the second heat dissipation channel 114 before exchanging heat with other components, and can directly contact the heating element 132 arranged in the first heat dissipation channel 113 and the electric control component 134 arranged in the second heat dissipation channel 114, so that more heat on the heating element 132 and the electric control component 134 can be taken away, and the heat dissipation effect can be improved.

The interior of the shell 110 is divided into the independent first heat dissipation channel 113 and the independent second heat dissipation channel 114, so that the heat dissipation of the heating element 132 and the heat dissipation of the electric control assembly 134 are mutually independent, the situation that wind after heat exchange with the heating element 132 flows to the electric control assembly 134 again is avoided as much as possible, and the heat dissipation effect on the heating element 132 and the electric control assembly 134 can be improved.

Referring to fig. 3 and 4, the cross-flow fan 120 includes a fan body 121, a fan bracket 122 and a vibration damping member 126, wherein the fan body 121 is mounted on the fan bracket 122, the fan bracket 122 is fixed with 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 fan body 121 is installed on the fan support 122, and the fan support 122 is fixed on the housing 110, and in the process of rotating the fan body 121, collision easily occurs between the fan body 121 and the fan support 122, abnormal sound is generated, and accordingly noise is generated. Similarly, the fan bracket 122 and the housing 110 are relatively displaced due to the rotation of the fan body 121, and are also prone to collision and abnormal noise, thereby generating noise. In the embodiment of the present application, the vibration damper 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, so that the noise generated by the collision of the components during the movement of the cross-flow fan 120 can be reduced, and the noise of the cooking apparatus 100 during the working process is reduced.

The fan bracket 122 is fixed to the housing 110 by a damper 126, and/or the damper 126 connects the fan body 121 and the fan bracket 122. The vibration damping member 126 may be disposed only between the fan body 121 and the fan bracket 122, or the vibration damping member 126 may be disposed only between the fan bracket 122 and the housing 110, or the vibration damping member 126 may be disposed between the fan body 121 and the fan bracket 122, or between the fan bracket 122 and the housing 110.

In some embodiments, the vibration damper 126 includes at least one of a vibration damper support 127, a vibration damper portion 128, and a vibration damper seat 129, the vibration damper support 127 being fixedly coupled to the housing 110, the fan support 122 being mounted on the vibration damper support 127, the vibration damper portion 128 and the vibration damper seat 129 being mated to the fan body 121 and coupled to the fan support 122.

The cross flow fan 120 is approximately long, two fan brackets 122 are arranged, the two fan brackets 122 are respectively arranged at two ends of the fan body 121, namely, two ends of the fan body 121 are fixedly connected with the shell 110 through the two fan brackets 122, and correspondingly, two vibration reduction brackets 127 are also arranged, and the vibration reduction brackets 127 are arranged in one-to-one correspondence with the fan brackets 122.

Wherein, damping support 127, damping portion 128 and damping seat 129 all have certain elasticity, in cross-flow fan 120 working process, if the displacement appears between fan body 121 and the fan support 122, fan body 121 can extrude damping portion 128 or damping seat 129, makes damping seat 129 warp, and fan body 121 can not direct with fan support 122 direct contact, has avoided appearing the collision between fan body 121 and the fan support 122, has reduced the noise that produces because of the collision between fan body 121 and the fan.

Similarly, if displacement occurs between the fan bracket 122 and the housing 110, the fan bracket 122 will squeeze the vibration reduction bracket 127, so that the vibration reduction bracket 127 is deformed, the fan bracket 122 will not directly contact with the housing 110, so that collision between the fan bracket 122 and the housing 110 is avoided, and noise generated by collision between the fan bracket 122 and the housing 110 is reduced.

The vibration damper 126 includes at least one of the vibration damper 127, the vibration damper 128 and the vibration damper 129, and it is explained that the vibration damper 126 may include only any one of the vibration damper 127, the vibration damper 128 and the vibration damper 129, may include only any two of the vibration damper 127, the vibration damper 128 and the vibration damper 129, and may include the vibration damper 127, the vibration damper 128 and the vibration damper 129 at the same time. In the following, how the damper bracket 127 connects the blower bracket 122 to the housing 110, and how the damper portion 128 and the damper seat 129 connect the blower body 121 to the blower bracket 122 will be described in detail, and when the damper 126 includes two or three of them, the three cases may be combined.

The vibration damping body 127a is connected with the fan bracket 122, and the fixing base 127b is fixedly connected with the housing 110, and because the fan body 121 is in a strip shape, the fixing base 127b and the vibration damping body 127a are arranged at an approximately included angle. The fixing base 127b may be horizontally disposed to be attached to the bottom wall of the housing 110, and the vibration damping body 127a may be disposed substantially vertically.

Through the vibration reduction protrusion 127d and the shell 110 contact, the direct contact area with the shell 110 can be reduced, the surface contact is changed into the line contact or the point contact, when the relative displacement exists 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 reduction protrusion 127d can be rapidly deformed to achieve the purpose of rapid buffering.

The outer wall of the vibration damping body 127a is provided with at least one vibration damping protrusion 127d, and if the vibration damping protrusion 127d is provided in plurality, the vibration damping protrusions 127d are provided on the outer wall of the vibration damping body 127a at intervals, the number of the vibration damping protrusions 127d can be set according to the length of the vibration damping body 127a in the axial direction of the cross-flow fan 120, and the longer the length of the vibration damping body 127a is, the more the number of the vibration damping protrusions 127d can be set.

As for the height of the vibration reduction protrusion 127d, it may be set according to the vibration reduction amount required for the entire vibration reduction bracket 127, and if the vibration reduction amount is larger, the height of the vibration reduction protrusion 127d may be set higher, and if the vibration reduction amount is smaller, the height of the vibration reduction protrusion 127d may be set smaller.

It is easy to understand that the bearings 121e and the motor 121c are respectively provided at both ends of the fan shaft 121b, that is, one end of the fan shaft 121b is connected to the motor 121c, and the other is fixed to the fan bracket 122 through the bearings 121 e. Similarly, during the movement, the fan body 121 may displace in the axial direction, and the bearing 121e is connected with the fan bracket 122 through the bearing 121e seat, so that the bearing 121e and the fan bracket 122 can be prevented from being in direct contact, and noise caused by collision is reduced.

Specifically, the whole vibration reduction seat 129 is arranged in the mounting hole 122a in a penetrating manner, the mounting hole 122a is clamped in the positioning clamping groove 129b, that is to say, the fan support 122 around the mounting hole 122a is clamped in the positioning clamping groove 129b, when the whole cross-flow fan 120 is axially or radially displaced, the fan support 122 abuts against the inner wall of the positioning clamping groove 129b, so that the vibration reduction seat 129 deforms, displacement between the bearing 121e and the fan support 122 can be buffered, and flexible contact between the fan support 122 and the bearing 121e is realized.

In some embodiments, the positioning slot 129b is disposed around the outer surface of the vibration damping seat 129.

The vibration damping seat 129 is substantially cylindrical, the bearing 121e hole is formed in one end face of the vibration damping seat 129, the positioning clamping groove 129b is annularly formed on the peripheral face of the vibration damping seat 129, and the bearing 121e hole and the positioning clamping groove 129b are arranged on the end face and the peripheral face, so that the layout of the vibration damping seat 129 can be reasonably utilized, and the volume of the vibration damping seat 129 can be reduced.

When the elastic portions 129c are arranged on the two opposite inner walls of the positioning clamping groove 129b, the elastic portions 129c can be arranged in a one-to-one correspondence manner, so that the same positions on two sides of the fan support 122 are in contact with the elastic portions 129c, and the risk of deformation of the fan support 122 is reduced.

The whole vibration damping seat 129 is made of an elastic structure, can be made of a silica gel material or a rubber material, can be made of other materials at present, and can ensure that the vibration damping seat 129 has certain elasticity.

In some embodiments, the stiffness of the vibration dampening parts 128, the vibration dampening shoe 129 and the vibration dampening brackets 127 is 40 degrees to 50 degrees.

If the hardness of the vibration reducing portion 128 is too high, the vibration reducing portion 128 may have a small shape in the event of a collision or vibration, which may result in a near rigid contact between the motor 121c and the fan bracket 122, and may easily cause damage to the motor 121 c. If the hardness of the vibration reduction portion 128 is small, the vibration reduction portion 128 is large in shape when collision or vibration occurs, and the motor 121c and the fan bracket 122 are still in rigid contact after reaching the limit position, the hardness of the vibration reduction portion 128 is set at 40-50 degrees, so that the vibration reduction portion 128 can play a role in buffering the motor 121c and the fan bracket 122 when displacement or collision occurs, the motor 121c or the fan bracket 122 is prevented from being damaged by direct collision, and noise generated by collision of the motor 121c and the fan bracket 122 can be avoided.

If the hardness of the damper seat 129 is too high, the damper portion 128 is small in shape in the event of a collision or vibration, which results in a near rigid contact between the bearing 121e and the fan bracket 122, and thus in a risk of damage to the bearing 121 e. If the hardness of the vibration damping seat 129 is small, the vibration damping seat 129 is large in shape when collision or vibration occurs, and the bearing 121e and the fan support 122 are still in rigid contact after reaching the limit position, the hardness of the vibration damping seat 129 is set at 40-50 degrees, so that the vibration damping seat 129 can play a role in buffering the bearing 121e and the fan support 122 when displacement or collision occurs, the direct collision is avoided to damage the bearing 121e or the fan support 122, and noise generated by collision of the bearing 121e and the fan support 122 can be avoided.

If the stiffness of the vibration damper support 127 is too high, the vibration damper support 127 may have a smaller shape in the event of a collision or vibration, which may result in a near rigid contact between the housing 110 and the fan support 122, and may easily cause damage to the fan support 122 and the housing 110. If the hardness of the vibration reduction support 127 is smaller, the vibration reduction support 127 has a larger shape when the collision or vibration occurs, and the housing 110 and the fan support 122 are still in rigid contact after reaching the limit position, the hardness of the vibration reduction support 127 is set at 40-50 degrees, so that the vibration reduction support 127 can play a role in buffering the housing 110 and the fan support 122 when displacement or collision occurs, the housing 110 or the fan support 122 is prevented from being damaged by direct collision, and noise generated by collision of the housing and the fan support 122 can be avoided.
