Detailed Implementation

[0031] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] Combination Figures 1 to 8 According to an example of the present invention, the cooking device 100 includes: a body 10, a microwave heating module 20, and at least two fans.

[0033] Specifically, the body 10 has a cooking cavity 11 and at least two heat dissipation ducts. The cooking cavity 11 is used to place items to be cooked, and the cooking cavity 11 may have an opening 12 through which the items to be cooked can be placed into the body 10. The body 10 may also be connected to a door 1313, which is used to open and close the opening 12. The at least two heat dissipation ducts inside the body 10 are independent of each other. Optionally, the number of heat dissipation ducts in the body 10 may include two, three, four, five or more. A microwave heating module 20 is disposed in the body 10, and the microwave heating module 20 may be configured to heat the items in the cooking cavity 11 using microwaves. The microwave heating module 20 is opposite to the at least two heat dissipation ducts. In addition, at least two fans are respectively corresponding to the at least two heat dissipation ducts to drive airflow, so as to dissipate heat from different areas of the microwave heating module 20 and optimize the heat dissipation effect.

[0034] According to the embodiments of the invention, the cooking device 100 is provided with at least two heat dissipation ducts to independently dissipate heat from the microwave heating module 20, thereby avoiding the problem that the microwave heating module 20 is too hot, which may cause it to malfunction or shorten its service life. This improves the service life and stability of the microwave heating module 20 and further enhances the heat dissipation effect of the cooking device 100.

[0035] For example, the microwave heating module 20 may include a microwave inlet channel 21, a microwave generator 22, and a microwave radio frequency unit 23. The microwave inlet channel 21, the microwave generator 22, and the microwave radio frequency unit 23 reach different temperatures during operation. In order to avoid mutual influence between the operating temperatures of the microwave heating modules 20, at least two heat dissipation ducts may include a first heat dissipation duct 31, a second heat dissipation duct 32, and a third heat dissipation duct 33, and at least two fans may include a first fan 41, a second fan 42, and a third fan 43. The first heat dissipation duct 31 is opposite to the microwave inlet channel 21. The first fan can be opposite to the first heat dissipation duct 31 to drive airflow through the first heat dissipation duct 31 to dissipate heat from the microwave inlet channel 21. The second heat dissipation channel is opposite to the microwave generator 22. The second fan can be opposite to the second heat dissipation duct 32 to drive airflow through the second heat dissipation duct 32 to dissipate heat from the microwave generator 22. The third heat dissipation duct 33 is opposite to the microwave radio frequency device 23. The third fan can be opposite to the third heat dissipation duct 33 to drive airflow through the third heat dissipation duct 33 to dissipate heat from the microwave radio frequency device 23. Driven by the first fan 41, the airflow enters the first heat dissipation duct 31 and exchanges heat with the microwave inlet channel 21, carrying away the heat of the microwave inlet channel 21 and reducing its temperature. Driven by the second fan 42, the airflow enters the second heat dissipation duct and exchanges heat with the microwave generator 22, carrying away the heat of the microwave generator 22 and achieving cooling of the microwave generator 22. Driven by the third fan 43, the airflow enters the third heat dissipation duct 33 and exchanges heat with the microwave radio frequency device 23, carrying away the heat of the microwave radio frequency device 23, which can effectively improve the heat dissipation effect of the microwave radio frequency device 23.

[0036] Optionally, such as Figure 1A door handle 131 can be connected to the front of the door body 1313. The door handle 131 can be connected to the door body 1313 to drive the door body 1313 to open and close the opening 12. The door handle 131 can be connected to the upper part of the door body 1313 and includes a first branch, a second branch and a third branch. The first branch is connected to the left part of the upper part of the door body 1313 in the left-right direction and extends forward. The second branch is connected to the right part of the upper part of the door body 1313 in the left-right direction and extends forward. The first branch and the second branch can be symmetrically distributed on the central axis of the door body 1313 in the left-right direction. The left end of the third branch is connected to the front end of the first branch and the right end of the third branch is connected to the front end of the second branch. The door body 1313, the first branch, the second branch and the third branch together form a space. The door body 1313 can be opened and closed by passing a hand through the space and grasping the third branch.

[0037] Combination Figure 3 and Figure 4 In some embodiments, the microwave heating module 20 includes a microwave inlet channel 21 and a microwave generator 22. One end of the microwave inlet channel 21 is connected to the microwave generator 22, and the other end is connected to the cooking cavity 11. The microwaves generated by the microwave generator 22 can be introduced into the cooking cavity through the microwave inlet channel, and the food is heated in the cooking cavity using the microwaves.

[0038] Optionally, at least two heat dissipation ducts include a first heat dissipation duct 31, at least a portion of the microwave inlet channel 21 passes through the first heat dissipation duct 31, and at least two fans include a first fan 41, which drives airflow through the first heat dissipation duct 31. Specifically, the microwave generator 22 may include a coupling connector 221, and the microwave inlet channel 21 may include an upper housing 211 and a lower base plate 212. The lower base plate 212 includes a first end and a second end. The first end is provided with a first stepped hole 2121, which is used to couple with the coupling connector 221 of the microwave generator 22. One end of the microwave generator 22 is connected to the microwave inlet channel 21. After the microwave generator 22 generates microwaves, the microwaves can be input into the microwave inlet channel 21 through the coupling connector 221. The other end of the microwave inlet channel 21 is connected to the cooking cavity 11, so the microwaves enter the cooking cavity 11 through the microwave inlet channel 21. Because the microwave generator 22 experiences energy loss when generating microwaves, this energy loss is dissipated as heat. The microwave generator 22 is connected to the microwave inlet channel 21 and undergoes heat conduction. Therefore, during operation, the temperature of the microwave inlet channel 21 rises. External airflow, driven by the first fan 41, enters the first heat dissipation duct 31. At least a portion of the microwave inlet channel 21 passes through the first heat dissipation duct 31. The airflow passes through the microwave inlet channel 21 for heat exchange, carrying away the heat from the microwave inlet channel 21 and reducing its temperature, thus achieving active heat dissipation of the microwave inlet channel 21. The working principle of this microwave generator 22 is the same as that of existing microwave generation principles and will not be described further here.

[0039] Combination Figure 5 In some embodiments, a first heat dissipation duct 31 is disposed on the top of the body 10, the body 10 has a first side 14 and a second side 15 opposite to each other in the left-right direction, a first fan 41 is disposed on the first side 14 of the body 10, and the first heat dissipation duct 31 is configured to extend along the first side 14 of the body 10 to the second side 15 of the body 10. Specifically, as Figure 4 A first air inlet 411 is provided on the outer left side wall of the body 10, opposite to the first fan 41. The air inlet of the first fan 41 is connected to the first air inlet 411, and the air outlet of the first fan 41 is connected to the first heat dissipation duct 31. The first air inlet 411, the air inlet of the first fan 41, the air outlet of the first fan 41, and the first heat dissipation duct 31 are connected in sequence to form a channel. Driven by the first fan 41, the external airflow can flow smoothly from left to right through the first heat dissipation duct 31. The first heat dissipation duct 31 is located at the upper part of the cooking cavity 11. The airflow carries away the heat of the microwave inlet channel 21 and the cooking cavity 11, realizing heat dissipation of the microwave inlet channel 21 and the cooking cavity 11, which facilitates the rapid cooling of the microwave inlet channel 21 and the cooking cavity 11, and improves the cooking efficiency and effect of food.

[0040] Optionally, the first fan 41 can be located on the top of the first side portion 14. The first fan 41 can include a first impeller and a first casing. The first impeller is rotatably connected to the first casing. The lower end of the first casing has an air inlet, which communicates with the first air inlet hole 411. The air outlet of the first casing communicates with the first heat dissipation duct 31. Driven by the first impeller, airflow can enter the first casing through the first air inlet hole 411. Driven by the first impeller, the airflow inside the first casing passes through the air outlet of the first casing and is input into the first heat dissipation duct 31, which can effectively improve the heat dissipation effect of the first heat dissipation duct 31. The first fan 41 can be a cross-flow fan. When the first impeller rotates, the blades push the air backward, forming a local low pressure, thereby drawing more air into the first fan 41. After the airflow passes through the first impeller, the airflow velocity increases, and the pressure also increases accordingly, realizing a large amount of airflow intake and exhaust.

[0041] Combination Figure 4 and Figure 5 In some embodiments, the outer wall of the second side portion 15 of the body 10 is provided with a first heat dissipation hole 412. The first heat dissipation hole 412 is opposite to the first heat dissipation duct 31. Driven by the first fan 41, the airflow enters the first heat dissipation duct 31 from the first air inlet 411 and passes through the first fan 41. It exchanges heat with the microwave inlet channel 21 and the cooking cavity 11. The airflow after heat exchange is directly discharged to the outside of the body 10 through the first heat dissipation hole 412, which shortens the channel for hot airflow to be discharged from the body and reduces wind resistance so that hot airflow can quickly flow out of the body 10, thereby improving the heat dissipation efficiency and effect of the microwave inlet channel 21 and the cooking cavity 11.

[0042] Combination Figures 3 to 5 In some embodiments, the first end of the microwave inlet channel 21 is connected to the microwave generator 22, and the second end is connected to the cooking cavity 11. The second end of the microwave inlet channel 21 is located within the first heat dissipation duct 31. After the microwave generator 22 generates microwaves, it couples with the first end of the microwave inlet channel 21, inputting the microwaves into the microwave inlet channel 21. The second end of the microwave inlet channel 21 is connected to the cooking cavity 11. The microwaves enter the top of the cooking cavity 11 through the second end of the microwave inlet channel 21 and may accumulate at the top of the cooking cavity 11, causing the temperature at the top of the cooking cavity 11 to rise. The second end of the microwave inlet channel 21 exchanges heat with the top of the cooking cavity 11, thereby causing the second end of the microwave inlet channel 21 to heat up. The second end of the microwave inlet channel 21 is located within the first heat dissipation duct 31. Driven by the first fan 41, the airflow exchanges heat with the second end of the microwave inlet channel 21 within the first heat dissipation duct 31, thereby achieving heat dissipation of the microwave inlet channel 21.

[0043] Combination Figure 6In some embodiments, the body 10 is provided with a stirring motor 16, which is located at the second end of the microwave inlet channel 21 to disperse the microwaves entering the cooking cavity 11. The stirring motor 16 is located in the first heat dissipation duct 31. Specifically, the upper shell 211 of the microwave inlet channel 21 may have a mounting hole 2111 at one end near the stirring motor 16. Two small protrusions are symmetrically distributed at the front and rear ends of the mounting hole 2111. The lower part of the stirring motor 16 is provided with a mounting base plate, which cooperates with the mounting hole 2111 of the upper shell 211. The bottom of the mounting base plate is provided with small recesses symmetrically distributed at the front and rear ends of the cooperation hole 161, which cooperate with the two small protrusions of the upper shell 211 to limit the stirring motor 16 and the upper shell 211. The stirring plate 16 is provided with a mating hole 161. The drive shaft 162 of the stirring motor 16 is connected to the connecting column 163. At least part of the projection of the drive shaft 162 on the vertical plane overlaps with the projection of the connecting column 163. The drive shaft 162 can pass through the mounting hole 2111 and the mating hole 161.

[0044] The lower base plate 212 of the microwave induction channel 21 includes a second end, which has a second stepped hole 2122. The connecting post 163 can pass through the second stepped hole 2122, so the connecting post 163 can move from bottom to top through the second stepped hole 2122 and be installed on the drive shaft 162. The lower part of the connecting post 163 is threaded, and the center of the stirring blade 164 has a circular hole 1641. The lower end of the connecting post 163 is connected to a bolt 1632, which is used to limit the position of the stirring blade 164 and prevent the stirring blade 164 from falling off the connecting post 163 when rotating. Since the stirring motor 16 loses energy during operation, the energy loss is dissipated in the form of heat. The external airflow enters the first heat dissipation duct 31 under the drive of the first fan 41. The airflow flows through the stirring motor 16 and absorbs the heat of the stirring motor 16, thereby reducing the temperature of the stirring motor 16 and achieving heat dissipation of the stirring motor 16.

[0045] Combination Figures 2 to 4 In some embodiments, the microwave heating module 20 further includes a microwave generator 22, at least two heat dissipation ducts including a second heat dissipation duct 32, with the microwave generator 22 opposite to the second heat dissipation duct 32, and at least two fans including a second fan 42, which drives airflow through the second heat dissipation duct 32 and the microwave generator 22. Specifically, the second fan 42 is located at the front of the microwave generator 22 and is positioned opposite to the microwave generator 22. The microwave generator 22 experiences energy loss during operation, which is dissipated as heat, resulting in a relatively high temperature on the microwave generator 22. External airflow, driven by the second fan 42, enters the second heat dissipation duct 32, flows through the microwave generator 22, and absorbs the heat generated by the microwave generator 22, thus achieving heat dissipation for the microwave generator 22.

[0046] Combination Figure 6 In some embodiments, the microwave generator 22 includes a plurality of heat sinks 222 stacked and having gaps. The space between adjacent heat sinks 222 is opposite to the second heat dissipation duct 32. The microwave generator 22 is connected to the plurality of heat sinks 222. The heat of the microwave generator 22 is transferred to the heat sinks 222. The provision of multiple heat sinks 222 increases the heat dissipation area of ​​the microwave generator 22. The airflow flows directly through the gaps between the heat sinks 222 through the second heat dissipation duct 32, which can accelerate the heat dissipation of the microwave generator 22, thereby improving the heat dissipation effect of the microwave generator 22.

[0047] In some embodiments, the microwave generator 22 includes a power supply 223, which is opposite to the second heat dissipation duct 32. The microwave generator 22 also includes a power supply bracket, which is mounted on the second side 15. The power supply 223 is mounted on the power supply bracket. Driven by the second fan 42, the airflow passes through the second heat dissipation duct 32 and flows directly through the power supply 223, carrying away the heat on the power supply 223 and reducing the temperature of the power supply 223.

[0048] In some embodiments, the microwave generator 22 is located on the side of the body 10, and the second heat dissipation duct 32 is opposite to the microwave generator 22 in the front-back direction. This facilitates heat dissipation for the microwave generator 22. Optionally, the rear wall of the body 10 is provided with a second heat dissipation hole 422, and the second heat dissipation hole 422, the microwave generator 22, and the second heat dissipation duct 32 are opposite to each other in the front-back direction. Specifically, a second air inlet 421 is provided on the right side wall of the outer side of the body 10 near the second fan 42. The air inlet of the second fan 42 is connected to the second air inlet 421, and the air outlet of the second fan 42 is connected to the microwave generator 22. The second air inlet 421, the air inlet of the second fan 42, the air outlet of the second fan 42, and the second heat dissipation duct 32 are connected in sequence to form a channel. Driven by the second fan 42, the airflow flows smoothly from the second air inlet 421 through the second fan 42 into the second heat dissipation duct 32. After exchanging heat with the power supply 223, the microwave generator 22, and the heat sink 222 on the microwave generator 22, the airflow flows directly out of the body 10 through the second heat dissipation hole 422, thus preventing the hot airflow from staying inside the body 10 for a long time.

[0049] Optionally, the second fan 42 can be mounted on the power supply bracket 2231 and installed at the rear of the power supply 223. The second fan 42 may include a second impeller and a second housing. The second impeller is rotatably connected inside the second housing. The front of the second housing has an air inlet, which communicates with a second air inlet hole 421. The air outlet of the second housing communicates with a second heat dissipation channel. Driven by the second impeller, airflow can enter the second housing through the second air inlet hole 421. The airflow inside the second housing, driven by the second impeller, passes through the air outlet of the second housing and enters the second heat dissipation channel 32, which can effectively improve the heat dissipation efficiency of the second heat dissipation channel. The second fan 42 can be a DC fan. A DC fan is directly driven by a DC power supply. Compared with an AC fan, a DC fan does not have brushes and a commutator, reducing friction and noise, while also reducing energy loss and extending service life.

[0050] Combination Figure 3 and Figure 7 In some embodiments, the microwave heating module 20 further includes a microwave radio frequency unit 23, at least two heat dissipation ducts including a third heat dissipation duct 33, the microwave radio frequency unit 23 being disposed within the third heat dissipation duct 33, and at least two fans including a third fan 43, the third fan 43 being used to drive airflow through the third heat dissipation duct 33. Specifically, the third fan 43 is disposed at the front of the microwave radio frequency unit 23, the bottom of the microwave radio frequency unit 23 is provided with a mounting plate, the upper and lower sides of the outer wall of the mounting plate are provided with four hooks 231, the outside of the microwave radio frequency unit 23 is provided with an air guide shroud 24, the air guide shroud 24 is provided with four mating ports 241 at positions opposite to the four hooks 231, the hooks 231 hook the mating ports 241 to fix the air guide shroud 24 to the outside of the microwave radio frequency unit 23; the right side of the air guide shroud 24 is provided with a raised portion to increase the air intake volume, and the air guide shroud 24 is connected to the third fan 43. The microwave radio frequency unit 23 is used to control the frequency and power of microwaves. During operation, the microwave radio frequency unit 23 generates heat. Driven by the third fan 43, the airflow enters the air guide shroud 24 and flows through the microwave radio frequency unit 23, carrying away the heat from the microwave radio frequency unit 23 and achieving heat dissipation of the microwave radio frequency unit 23.

The third heat dissipation hole 432, the third heat dissipation duct 33, and the third fan 43 are opposite each other in the front-to-back direction. A third air inlet 431 is provided on the right side wall of the body 10 near the third fan 43. The third air inlet 431 is connected to the air inlet of the third fan 43, the air outlet of the third fan 43 is connected to the air inlet of the air guide shroud 24, and the air outlet of the air guide shroud 24 is connected to the third heat dissipation hole 432. The third air inlet 431, the air inlet of the third fan 43, the air outlet of the third fan 43, the air inlet of the air guide shroud 24, and the air outlet of the air guide shroud 24 are sequentially connected to form a channel, and the airflow passes through the third fan. Driven by 43, air flows into the third heat dissipation duct 33 from the third air inlet 431. The airflow flows into the air inlet of the air guide shroud 24 and passes through the microwave radio frequency unit 23, absorbing the heat on the microwave radio frequency unit 23. The airflow then flows out from the air outlet of the air guide shroud 24. The air outlet of the air guide shroud 24 is connected to the third heat dissipation hole 432. The hot airflow can be directly discharged from the air outlet of the air guide shroud 24 to the outside of the body 10 without flowing into the inside of the body 10, thereby improving the heat dissipation efficiency of the microwave radio frequency unit 23.

The third impeller is rotatably connected inside the third housing. The front of the third housing has an air inlet, which communicates with a third air inlet hole 431. The air outlet of the third housing communicates with a third heat dissipation duct 33. Driven by the third impeller, airflow can enter the third housing through the third air inlet hole 431. The airflow inside the third housing, driven by the third impeller, passes through the air outlet of the third housing and enters the third heat dissipation duct 33, which can improve the heat dissipation effect of the third heat dissipation duct 33. The third fan 43 can be a DC fan, thereby reducing operating noise and fan energy consumption.

[0053] Combination Figure 3Optionally, in some embodiments, the cooking device 100 further includes a steam generator 25 for generating steam.
