Referring to fig. 1 and 3, a cooking apparatus 100 according to an embodiment of the present invention includes a cavity 10, a door 20, a control board 30, at least one electric component 40, and a cooling assembly 50, the door 20 being connected to the cavity 10; the control panel 30 is arranged above the door body 20 at intervals, and at least one air inlet and at least one air outlet are formed between the control panel 30 and the door body 20; at least one electrical component 40 is connected to the control board 30; the cooling assembly 50 is mounted on top of the cavity 10, the cooling assembly 50 comprising a cooling fan 51, the cooling assembly 50 being adapted to establish an air duct from the at least one air inlet to the at least one air outlet when the cooling fan 51 is turned on, the air duct passing through the at least one electrical component 40.

Specifically, the cavity 10 is used to provide space for heating, and the space of the cavity 10 may be rectangular, providing enough space. In one example, the cooking apparatus 100 may be a microwave cooking apparatus 100, and the cavity 10 may have good sealing leakage-proof performance, ensuring that microwaves of the cooking chamber do not leak. A control board 30 may be provided at the front end of the top of the chamber 10. In some embodiments, the control board 30 may also be disposed at left and right portions of the cavity 10 according to the different positions where the electrical components 40 are disposed. In other examples, the cooking apparatus 100 may be cooking using other heating means, such as heating using one or a combination of steam, hot air, gas, etc.

Specifically, the user can install the cooking apparatus 100 in the groove space in the installation body (such as a wall body and a cabinet body), so that the upper surface, the lower surface, the left surface, the right surface and the rear surface of the cavity 10 are spaced from the installation body by a certain distance, and only the surface of the door body 20 is exposed out of the installation body, thereby realizing an embedded installation mode and reducing the space occupation.

The door 20 may be engaged with the cavity 10 to close the cavity 10, so that the cavity 10 forms a closed space when the cooking apparatus 100 is operated. In one embodiment, the door 20 is rotatably connected to the chamber 10, and when the door 20 is rotated to be opened along one side, the front surface of the chamber inside the chamber 10 is exposed, and a front open space connected to the chamber is formed. The door body 20 may be a pull-down door body 20, or a side-open door body 20. In other embodiments, the door 20 may be connected to the cavity 10 in a retractable manner.

The user sends food to the inner chamber of the cavity 10 through the front open space, performs operations such as heating, and after the cooking apparatus 100 is completed, the food is taken out from the cavity 10 through the front open space.

The control board 30 may control the operation of the cooking apparatus 100 to perform a variety of functions including, but not limited to, steaming, baking, heating functions, etc.

The space between the control board 30 and the door body 20 may be formed with at least one air inlet and at least one air outlet. The opening directions of the air inlet and the air outlet may be the same, for example, both the air inlet and the air outlet may be toward the front of the cooking apparatus 100.

In one embodiment, the at least one air inlet may include three air inlets, a first air inlet 61, a second air inlet 62, and a third air inlet 63, respectively. The at least one air outlet may comprise two air outlets, a first air outlet 71 and a second air outlet 72, respectively, as shown in fig. 1.

In other embodiments, a dual inlet and single outlet configuration may be employed. Specifically, in the double-air-inlet single-air-outlet structure, at least one air inlet may include two air inlets, namely, the first air inlet 61 and the second air inlet 62, and at least one air outlet may include only one air outlet, and may be the first air outlet 71 or the second air outlet 72, so, compared with the three-air-inlet double-air-outlet structure of the present embodiment, the number of the third air inlet 63 and the number of the air outlets are reduced.

With continued reference to fig. 1, a cooling assembly 50 is mounted on top of the cavity 10 between a housing (not shown) of the cooking apparatus 100 and a void formed by the cavity 10. The cooling unit 50 includes a cooling fan 51, and the cooling fan 51 is a device for cooling air by sucking air and discharging the air.

The cooling fan 51 can drive air to be sucked from the air inlet and blown out from the air outlet, so that an air channel is formed, and the air channel is positioned between the shell and the cavity 10, so that when the cooling fan 51 works, the air in and out flows in the air channel to dissipate heat of the control board 30, the electric components 40 and the cavity 10.

The cooling fan 51 may be a coaxial shaded pole motor double-impeller centrifugal fan or other double-impeller fans.

The control board 30 may control the on and off states of the cooling fan 51.

The cooking apparatus 100 of the embodiment of the present invention may include, but is not limited to, microwave ovens, steamers, oven-steam-all-in-one, and the like.

According to the cooking device 100 provided by the embodiment of the invention, the cooling fan 51 at the top of the cavity 10 is used for establishing the air channel from the air inlet to the air outlet to cool the electric part 40, so that the heat dissipation circulation is formed at the top of the cavity 10, the overall heat dissipation capacity is greatly increased, the heat dissipation effect is achieved, and the purpose of installing the cabinet-free air channel is achieved.

Referring to fig. 1 and 2, in some embodiments, at least one electrical component 40 includes a transformer 41 positioned at the top of the cavity 10, at least one air inlet includes a first air inlet 61, at least one air outlet includes a first air outlet 71, an air duct includes a first air duct 81, the cooling assembly 50 is configured to establish the first air duct 81 from the first air inlet 61 to the first air outlet 71 when the cooling fan 51 is turned on, and the first air duct 81 passes through the transformer 41.

When the cooling assembly 50 is in operation, the cooling fan 51 is turned on to drive air to circulate, and the air enters the first air duct 81 from the first air inlet 61 and is discharged from the first air outlet 71.

The transformer 41 can generate heat in the working process, and the first air duct 81 passes through the transformer 41 to take away part of heat, so that the heat dissipation effect of the transformer 41 is achieved. The transformer 41 may be a step-up transformer 41 for supplying power to the electric components 40 operating at high voltage, for example, a magnetron or the like.

In this way, the cooling fan 51 can radiate heat from the transformer 41 through the first air duct 81.

Referring to fig. 2 to 5, in some embodiments, at least one electrical component 40 includes an electronic board 42, the electronic board 42 is located at the back of the cavity 10, the cooling assembly 50 includes a first air duct 81 52, a first channel 521 and a second channel 522 are formed in the first air duct 81 52, the transformer 41 is located in the first channel 521, the first channel 521 communicates with the first air inlet 61 and the first air outlet 71, and an outlet of the second channel 522 faces the electronic board 42.

The electronic board 42 is mounted on the back of the chamber 10, and the electronic board 42 may include a plurality of input ports and output ports, wherein the input ports may be connected to a power source and power the control board 30 through the output ports.

In this embodiment, the first air duct 81 may adopt a double-air-outlet volute structure, and the double-air-outlet volute structure makes a part of air blow out from the front to dissipate heat of the transformer 41, and another part blow out from the back to dissipate heat of the electronic board 42 on the back.

Referring to fig. 4 and 5, the first air duct 81 has a first channel 521 and a second channel 522 formed in the first air duct 81, the first channel 521 is communicated with the first air inlet 61 and the first air outlet 71, the first channel 521 may be a portion of the first air duct 81, and the second channel 522 may guide the air flowing through the first channel 521 to the outlet of the second channel 522, so that the air also flows in the second channel 522 to the electronic board 42 at the back of the cavity 10, thereby implementing heat dissipation to the electronic board 42.

In this way, the air volume on the transformer 41 side is split, a part of the air volume still heat dissipates heat to the transformer 41 forward, and a part of the air volume dissipates heat to the electronic board 42 on the back backward, thereby achieving heat dissipation of more electric components 40.

Referring to fig. 1, in some embodiments, at least one electrical component 40 includes a microwave generating device 43 located at the top of the cavity 10, at least one air inlet includes a second air inlet 62, at least one air outlet includes a second air outlet 72, the air duct includes a second air duct 82, the cooling assembly 50 is configured to establish the second air duct 82 from the second air inlet 62 to the second air outlet 72 when the cooling fan 51 is turned on, and the second air duct 82 passes through the microwave generating device 43.

The microwave generating device 43 is used for generating microwaves, and the microwave generating device 43 is located at the top of the cavity 10 and provides microwave energy for the cavity 10. The microwave generating means 43 emits microwaves to the food placed in the cavity 10. In use, microwave radiation is applied to the food in the cavity 10 to heat the food.

When the microwave generating device 43 works, heat is generated, at this time, the cooling assembly 50 works, the cooling fan 51 is started, air is driven to enter the second air duct 82 from the second air inlet 62, the second air duct 82 is discharged from the second air outlet 72, and the heat generated by the microwave generating device 43 is taken away by the air circulation of the second air duct 82, so that heat dissipation of the microwave generating device 43 is realized.

In this way, the cooling fan 51 can radiate heat from the microwave generating device 43 through the second air duct 82.

In particular, in the embodiment shown in fig. 3, the microwave generating means 43 may comprise a magnetron. In other embodiments, the microwave generating device 43 may include a semiconductor microwave source.

In some embodiments, the cooling assembly 50 includes a second air duct member 53, and a third channel is formed in the second air duct member 53, where the microwave generating device 43 is located in the third channel, and the third channel communicates with the second air inlet 62 and the second air outlet 72.

In the embodiment shown in fig. 3, the second air duct member 53 may employ a single outlet volute structure. The second air duct member 53 is provided with a third channel, the third channel is communicated with the second air inlet 62 and the second air outlet 72, and the third channel can guide circulated air to the outlet of the third channel, so that the air can circulate in the third channel to the microwave heating device at the top of the cavity 10, and heat dissipation of the microwave generating device 43 is realized.

In some embodiments, the second air duct member 53 may also adopt a double-air-outlet volute structure, so that a part of air is blown out from the front to dissipate heat from the microwave generator 43, and another part of air is blown out from the back to dissipate heat from the back electronic board 42.

In the embodiment shown in fig. 1, the cooling fan 51 is a bilobed centrifugal fan, and radiates heat from the microwave generator 43 and the transformer 41. In this case, the air volume of the heat radiation to the microwave generator 43 and the transformer 41 is substantially the same. Since the microwave generating device 43 generates more heat than the transformer 41 when the cooking apparatus 100 is operated, the amount of air for radiating the transformer 41 can be partially divided without affecting the radiating effect of the transformer 41. Therefore, the first air duct 81 member 52 adopts a double-air-outlet volute structure to split the air quantity at the side of the transformer 41, a part of the air quantity still dissipates heat to the transformer 41 forwards, and a part of the air quantity dissipates heat to the electronic board 42 at the back backwards, so that the full utilization of air flow is realized.

Referring to fig. 1, in some embodiments, the first air inlet 61 and the first air outlet 71 are located on the left side of the top of the cavity 10, and the second air inlet 62 and the second air outlet 72 are located on the right side of the top of the cavity 10.

The first air inlet 61 and the first air outlet 71 are located at the left side of the top of the cavity 10, and the flow path from the air entering the first air inlet 61 to the air blowing out the first air outlet 71 passes through most of the area of the left side of the top of the cavity 10, so as to dissipate heat of components at the left side of the top of the cavity 10.

The second air inlet 62 and the second air outlet 72 are located on the right side of the top of the cavity 10, and the flow path from the air entering the second air inlet 62 to the air blowing out the second air outlet 72 passes through most of the area on the right side of the top of the cavity 10, so as to dissipate heat of components on the right side of the top of the cavity 10.

In some embodiments, the transformer 41 and other components on the left side of the top of the cavity 10 are installed on the left side of the top of the cavity 10, the first air inlet 61 and the first air outlet 71 are located on the left side of the top of the cavity 10, and when the cooling fan 51 works, the air flow of the first air duct 81 can radiate heat from the transformer 41, the other components on the left side and the electronic board 42 on the back of the cavity 10. The right side of the top of the cavity 10 is provided with the microwave generating device 43 and other components on the right side, the second air inlet 62 and the second air outlet 72 are positioned on the right side of the top of the cavity 10, and the second air duct 82 can radiate heat from the microwave heating device and other components on the right side when the cooling fan 51 works.

In this way, the left and right areas are respectively cooled by the different air channels, and the air inlet quantity of the whole cooling is improved, so that the efficiency of the cooling fan 51 is improved.

With continued reference to fig. 1, in some embodiments, the at least one electrical component 40 includes the lighting component 44 and the motor 45, the at least one air intake includes the third air intake 63, the third air intake 63 is located in the middle of the top of the cavity 10, the air duct includes the third air duct 83 and the fourth air duct 84, the cooling assembly 50 is configured to create the third air duct 83 from the third air intake 63 to the first air outlet 71 when the cooling fan 51 is turned on, and create the fourth air duct 84 from the third air intake 63 to the second air outlet 72, and the third air duct 83 and the fourth air duct 84 have a common air duct 85 that passes through the lighting component 44 and the motor 45.

The illumination member 44 is located at a side of the top middle of the cavity 10 near the door 20, the illumination member 44 may use an LED lamp, and the illumination member 44 may illuminate the cavity 10 when the cooking apparatus 100 is operated.

The motor 45 is located at the top center of the cavity 10, and the motor 45 can drive the turntable inside the cavity 10 to rotate at a constant speed, so that when a user heats the cooking apparatus 100, the motor 45 drives the turntable to rotate, and foods on the turntable are heated uniformly.

When the lighting element 44 and the motor 45 are operated, a certain amount of heat is generated, and at this time, the cooling fan 51 is operated, and air enters from the third air inlet 63 and is blown out from the first air outlet 71 and the second air outlet 72. When air enters from the third air inlet 63 and is blown out from the first air outlet 71, a third air duct 83 is formed, and the third air duct 83 passes through the lighting element 44 and the motor 45; when air enters from the third air inlet 63 and is blown out from the second air outlet 72, a fourth air duct 84 is formed, and the fourth air duct 84 also passes through the lighting element 44 and the motor 45.

The air enters the third air inlet 63, passes through the lighting element 44 and the motor 45 before being split into the first air outlet 71 and the second air outlet 72, and the air flowing path is a common air duct 85 of the third air duct 83 and the fourth air duct 84.

Thus, the middle area of the top of the cavity 10 and the left and right heat dissipation areas form a heat dissipation cycle, so that the overall heat dissipation capacity is increased to a great extent, and the heat dissipation effect is achieved.

In some embodiments, at least one electrical component 40 includes a filter plate 46 positioned at the top of the cavity 10, and a first air duct 81 passes through the filter plate 46.

A filter plate 46 is mounted on top of the chamber 10, the filter plate 46 being able to inhibit the conduction of mains in the plate out and also to prevent external disturbances from being conducted into the control board 30.

When the cooling fan 51 is operated, the cool air circulates from the first air duct 81 to remove part of the heat generated by the filter plate 46.

In this way, the cooling fan 51 may radiate heat from the filter plate 46 through the first air duct 81.

In certain embodiments, filter plate 46 is positioned upstream of transformer 41 in the air flow.

When the cooling fan 51 works, left cold air is sucked from the first air inlet 61 to suck and dissipate heat in the area of the filter plate 46, then enters the spiral case of the cooling fan 51, and the design of the spiral case with double air outlets ensures that part of air is blown out from the front to dissipate heat of the transformer 41, and the other part of air is blown out from the back to dissipate heat of the electronic board 42 at the back.

Since the filter plate 46 generates less heat when operated than the transformer 41, the filter plate 46 upstream of the air flow is prevented from being adversely affected by the heat of the transformer 41. Further, the transformer 41 is disposed near the impeller air outlet of the cooling fan 51, so that the heat dissipation effect on the transformer 41 is better.

In certain embodiments, at least one electrical component 40 includes an energy storage element 47 positioned within cavity 10, and second air duct 82 passes through energy storage element 47.

The electrical component 40 comprises an energy storage element 47, the energy storage element 47 may employ a capacitance, an inductance, or both a capacitance and an inductance, and the energy storage element 47 is used to stabilize the magnetron current.

When the cooling fan 51 is operated, the cool air circulates from the second air duct 82 to remove part of the heat generated by the energy storage element 47.

In this way, the cooling fan 51 may radiate heat from the energy storage element 47 through the second air duct 82.

In certain embodiments, the energy storage element 47 is located upstream of the microwave generating device 43.

When the cooling fan 51 works, right cold air is sucked from the second air inlet 62 to suck and dissipate heat in the area of the energy storage element 47, then enters the spiral case of the cooling fan 51, and if the spiral case of a single air outlet is adopted, the cold air is blown out from the right front to dissipate heat of the microwave generating device 43; if the double-air-outlet volute is adopted, part of air is blown out from the front to dissipate heat of the microwave heating device, and the other part of air is blown out from the back to dissipate heat of the electronic board 42 on the back.

Since the energy storage element 47 generates less heat when operating than when the microwave heating device is operating, the energy storage element 47 upstream of the air flow is protected from the adverse effects of the heat of the microwave heating device. Further, the microwave heating device is arranged close to the impeller air outlet of the cooling fan 51, so that the heat dissipation effect of the microwave heating device is better.
