[0038] Next, reference is made to Figures 1-7 a cooking device 100 according to an embodiment of the present invention. The cooking device 100 can be configured as a microwave oven or other device with a microwave heating function, and the cooking device 100 can introduce microwaves into the cooking cavity 11 from different directions, which is beneficial to more evenly heating the food in the cooking cavity 11 by microwaves and improving the heating efficiency of the food.

[0039] As Figures 1-7 shown, a cooking device 100 according to an embodiment of the present invention includes a device main body 1 and a waveguide assembly.

[0040] A cooking cavity 11 is formed inside the device main body 1. The cooking cavity 11 can be used to place food, and the food can be heated and cooked inside the cooking cavity 11. The device main body 1 is provided with a first microwave feed port 12 and a second microwave feed port 13. The waveguide assembly is installed outside the device main body 1. The waveguide assembly forms a waveguide channel, and the waveguide channel is respectively connected to the first microwave feed port 12 and the second microwave feed port 13. Among them, the waveguide assembly can generate microwaves or access microwaves, and the generated or accessed microwaves can enter the waveguide channel. The microwaves can move along the waveguide channel to the first microwave feed port 12 and the second microwave feed port 13, and then can enter the cooking cavity 11 from the first microwave feed port 12 and the second microwave feed port 13, realizing the introduction of microwaves at different positions and enhancing the cooking effect of the food in the cooking cavity 11.

[0041] Therefore, by arranging the waveguide assembly outside the device main body 1, not only can microwaves be generated or accessed, but also the occupation of the space inside the cooking cavity 11 by the waveguide assembly can be reduced, ensuring the capacity inside the cooking cavity 11 and increasing the amount of food cooked.

[0042] Among them, the first microwave feed port 12 is used to introduce microwaves into the cooking cavity 11 along a first direction, and the second microwave feed port 13 is used to introduce microwaves into the cooking cavity 11 along a second direction. The first direction intersects with the second direction. That is to say, the microwaves in the waveguide channel can enter the cooking cavity 11 along the first direction through the first microwave feed port 12. At the same time, the microwaves in the waveguide channel can also enter the cooking cavity 11 along the second direction through the second microwave feed port 13. The intersection of the first direction and the second direction belongs to different directions. Thus, the microwaves can enter the cooking cavity 11 from different directions and angles through the first microwave feed port 12 and the second microwave feed port 13, realizing the mixing of microwaves in two directions, and the microwaves entering from different directions can fill different positions in the cooking cavity 11, so that the microwaves in the cooking cavity 11 can be more uniform, which is beneficial to heating the food from different directions and angles and beneficial to making the cooking effect of the food more uniform.

[0043] According to the cooking device 100 of the embodiment of the present invention, the waveguide assembly can introduce microwaves into the cooking cavity 11 from different directions, realizing microwave heating of the food from different directions, making the microwaves in the cooking cavity 11 more uniform, avoiding the concentration of microwaves in some areas of the cooking cavity 11, improving the cooking effect of the food, and enhancing the user experience.

[0044] In some embodiments, the waveguide assembly includes a waveguide structure 2, and the waveguide channel is formed in the waveguide structure 2. In other words, the waveguide structure 2 is constructed as a hollow tubular structure. The waveguide structure 2 can access microwaves and can guide the transmission direction of the microwaves, that is, realize the directional guidance of the microwaves and accurately transport the microwaves to the target area in the cooking cavity 11.

[0045] Among them, the waveguide structure 2 includes a first waveguide 21. The first waveguide 21 includes a connected first waveguide portion 211 and a second waveguide portion 215. The first waveguide portion 211 and the device main body 1 are distributed in a first direction and are used for introducing microwaves toward the first microwave feed port 12. The second waveguide portion 215 and the device main body 1 are distributed in a second direction and are used for introducing microwaves toward the second microwave feed port 13.

[0046] That is to say, the first waveguide 21 includes two bent and connected parts, namely the first waveguide portion 211 and the second waveguide portion 215, and the first waveguide portion 211 and the second waveguide portion 215 are respectively located in different directions of the device main body 1. Microwaves outside the waveguide structure 2 can enter the waveguide channel from any one of the first waveguide portion 211 and the second waveguide portion 215, can be dispersed in the first waveguide portion 211 and the second waveguide portion 215, and then enter the cooking cavity 11 from different directions of the first waveguide portion 211 and the second waveguide portion 215. Thus, the dispersed introduction of microwaves can be realized, and the uniformity of microwaves in the cooking cavity 11 can be improved.

[0047] Among them, that is to say, when setting the first waveguide 21, the inlet of the first waveguide 21 can be set at the first waveguide portion 211, that is, this inlet is located in the first direction of the device main body 1, or the inlet of the first waveguide 21 can be set at the second waveguide portion 215, that is, this inlet is located in the second direction of the device main body 1, which is beneficial to improving the flexibility of the inlet of the first waveguide 21, reducing the setting difficulty, and facilitating the realization of the overall layout.

[0048] In some embodiments, the first direction is along the up and down direction. The first waveguide portion 211 is located at the bottom of the device main body 1. The first waveguide portion 211 and the device main body 1 are distributed in the up and down direction, and the first waveguide portion 211 is installed below the device main body 1, so that the microwaves in the first waveguide portion 211 can enter the cooking cavity 11 from the bottom of the device main body 1 through the first microwave feed port 12. In other words, the first waveguide portion 211 can act on the food from the bottom of the cooking cavity 11 with microwaves to realize microwave heating from bottom to top.

[0049] And / or, the second direction is along the left and right direction of the device main body 1, that is, the second waveguide portion 215 and the device main body 1 are distributed in the left and right direction. The second waveguide portion 215 can be arranged on the left side of the device main body 1, or can be arranged on the right side of the device main body 1, or the second waveguide portion 215 can be arranged on both the left side and the right side of the device main body 1, so that the microwaves in the second waveguide portion 215 can enter the cooking cavity 11 through the second microwave feed port 13, realizing microwave conduction in the left and right direction, that is, being able to perform microwave heating on the food in the left and right direction.

[0050] Thus, microwaves can enter the cooking cavity 11 from two different directions, namely the up-down direction and the left-right direction, to achieve food heating in the cross direction. Furthermore, the microwave distribution in the cooking cavity 11 becomes more uniform, enabling uniform heating of the food and improving the cooking effect on the food.

[0051] In some embodiments, there are two second waveguide parts 215, and the two second waveguide parts 215 are respectively connected to the first waveguide part 211, and the two second waveguide parts 215 are respectively located on both sides of the device main body 1. That is, in some embodiments, as Figure 6 shown, the second waveguide part 215 can be set to one. In other embodiments, as Figure 5 shown, the second waveguide part 215 can be set to two, and the two waveguide parts can respectively introduce microwaves into the cooking cavity 11.

[0052] Specifically, in actual setting, the two second waveguide parts 215 can be symmetrically distributed on both sides of the device main body 1, that is, the second microwave feeding ports 13 corresponding to the two second waveguide parts 215 can be symmetrically distributed, so that the microwaves at the two second microwave feeding ports 13 can be directly introduced from the directions facing each other. In this way, the second microwave feeding ports 13 on the left and right sides of the device main body 1 and the first microwave feeding port 12 located at the bottom of the device main body 1 can introduce microwaves into the cooking cavity 11 from three directions, which is more conducive to realizing the uniform introduction of microwaves and enhancing the cooking effect in the cooking cavity 11.

[0053] Furthermore, as Figure 5 shown, the two second waveguide parts 215 are spaced apart along the left-right direction, and the first waveguide part 211 is connected to the bottoms of the two second waveguide parts 215, so that the first waveguide tube 21 is configured as a U-shaped structure. At the same time, as Figure 5 shown, a first microwave feeding port 12 is provided at the bottom of the device main body 1, and the first waveguide part 211 faces upwards and is directly opposite to the first microwave feeding port 12, so that the microwaves in the first waveguide part 211 can be introduced into the first microwave feeding port 12 and then enter the cooking cavity 11. In addition, second microwave feeding ports 13 are provided on the left and right sides of the device main body 1, and the second waveguide part 215 is in direct communication with the second microwave feeding port 13 along the left-right direction, so that the microwaves in the second waveguide part 215 can enter the cooking cavity 11 from the second microwave feeding port 13.

[0054] Thus, external microwaves can enter the cooking cavity 11 from two different directions through the first microwave feeding port 12 and the second microwave feeding port 13, realizing the mixed introduction of microwaves and enhancing the uniformity of food cooking.

[0055] In some embodiments, the waveguide structure 2 further includes a second waveguide 22. The waveguide channel includes a first channel formed in the first waveguide 21 and a second channel provided in the second waveguide 22. The first channel is provided with a first microwave inlet 212, and the second channel is provided with a microwave guiding inlet 221 and a microwave guiding outlet 222. The first microwave inlet 212 is communicated with the microwave guiding outlet 222. The first channel is used to introduce microwaves to the first microwave feeding port 12 and the second microwave feeding port 13.

[0056] Thus, by providing the second waveguide 22, the external microwaves can be introduced into the second waveguide 22 from the microwave guiding inlet 221, and the microwaves are guided along the second channel in the second waveguide 22 to the microwave guiding outlet 222, and then introduced from the microwave guiding outlet 222 into the first microwave inlet 212, and then from the first microwave inlet 212 through the first channel into the cooking cavity 11 from the first microwave feeding port 12 and the second microwave feeding port 13 respectively, so that the guiding of microwaves in the waveguide structure 2 can be realized, and the structure is simple and the setting is convenient.

[0057] Among them, by providing the second waveguide 22, the introduction of microwaves between the external microwaves and the first waveguide 21 can be realized, that is, by providing the second waveguide 22, the difficulty of introducing external microwaves can be reduced. At the same time, the limitation on the relative position between the microwave source and the first waveguide 21 is reduced, and the setting difficulty of the waveguide structure 2 is reduced.

[0058] In some embodiments, the waveguide assembly further includes a magnetron 3. The magnetron 3 is communicated with the microwave guiding inlet 221. In other words, the microwaves can be introduced into the microwave guiding inlet 221 through the magnetron 3 and then into the second waveguide 22 to realize the introduction of microwaves. Among them, the magnetron 3 can be used to generate microwave energy. Thus, the waveguide assembly including the magnetron 3 can generate microwave energy inside the cooking device 100 without setting an external microwave source, reducing the setting difficulty and cost.

[0059] Moreover, by communicating the magnetron 3 with the microwave guiding inlet 221, the microwaves generated by the magnetron 3 can be introduced from the second waveguide 22 into the first waveguide 21, and then the conduction of microwaves is realized, that is, the setting of the magnetron 3 is not limited by the position of the first microwave inlet 212 of the first waveguide 21, which is beneficial to improving the flexibility of the position setting of the magnetron 3 and reducing the setting difficulty.

[0060] In some embodiments, the second waveguide 22 and / or the magnetron 3 are both located on the side of the first waveguide 21 away from the device body 1. Among them, the first waveguide portion 211 of the first waveguide 21 is located at the bottom of the device body 1, and the second waveguide portion 215 of the first waveguide 21 is located at the side of the device body 1. That is, the second waveguide 22 can be arranged at the bottom of the first waveguide 21 or outside the second waveguide portion 215, and the magnetron 3 can be arranged at the bottom of the first waveguide portion 211 or outside the second waveguide portion 215.

[0061] Specifically, as Figure 5 and Figure 6 shown, the second waveguide 22 is configured as a box shape, and the second waveguide 22 is installed below the first waveguide 21, that is, the second waveguide 22 is connected to the first waveguide portion 211. Thus, the space below the first waveguide 21 can be effectively utilized. At the same time, as Figure 5 and Figure 6 shown, the magnetron 3 is also arranged below the first waveguide 21. For example, the magnetron 3 is arranged below the first waveguide portion 211. In this way, the second waveguide 22 and the magnetron 3 can both be installed below the first waveguide 21, realizing the utilization of the space in the vertical direction of the cooking device 100, that is, increasing the vertical height of the cooking device 100, reducing the space occupied by the cooking device 100 in the horizontal direction, and reducing the requirement of the cooking device 100 for the floor area.

[0062] In some embodiments, the first microwave inlet 212 and the microwave outlet 222 are communicated along the first direction. Among them, the second waveguide 22 is installed below the first waveguide portion 211, and the first microwave inlet 212 and the microwave outlet 222 are communicated in the up-and-down direction, that is, the first microwave inlet 212 is arranged at the bottom of the first waveguide portion 211. At the same time, the microwave outlet 222 is arranged at the upper part of the second waveguide 22, so that the microwave of the microwave outlet 222 enters the first waveguide 21 upward from the first microwave inlet 212. In this way, during actual installation, there is no need to set an additional connection structure between the second waveguide 22 and the first waveguide 21, and the two can be stacked and assembled, with a simple structure and convenient installation.

[0063] And, the magnetron 3 and the microwave inlet 221 are communicated along the second direction. Among them, the magnetron 3 and the second waveguide 22 are connected in the left-right direction, and the outlet of the magnetron 3 and the microwave inlet 221 are communicated in the left-right direction. That is, there is no need to set an additional connection structure between the magnetron 3 and the second waveguide 22, and the two can be connected in a fitting manner in the left-right direction to reduce the setting of connecting parts and reduce the setting cost. And as Figure 5As shown in the figure, the magnetron 3 is located on the left side of the second waveguide 22, and a socket tube portion 31 is formed on the right side of the magnetron 3. A microwave inlet 221 is provided on the left side surface of the second waveguide 22. When the magnetron 3 and the second waveguide 22 are assembled, the socket tube portion 31 extends into the microwave inlet 221 to achieve socket connection and realize compact installation.

[0064] In some embodiments, a stirring structure 41 is further provided in the cooking cavity 11. The stirring structure 41 is rotatably installed on the device main body 1. The stirring structure 41 can stir the microwave entering the cooking cavity 11, that is, actively intervene in the microwave conduction path, so that the microwave diffuses more dispersedly in the cooking cavity 11.

[0065] Therefore, when the cooking device 100 of the present invention performs microwave introduction, the microwave can enter the cooking cavity 11 not only from two different outlets, namely the first microwave feed port 12 and the second microwave feed port 13, to realize the dispersed introduction of the microwave, but also during the microwave introduction process, the dispersed effect of the microwave can be enhanced through the stirring structure 41, and further enhance the cooking effect of the microwave on the food.

[0066] Among them, the stirring structure 41 can be arranged at the first microwave feed port 12, or can be arranged at the second microwave feed port 13, or can be arranged at the connection between the first microwave feed port 12 and the second microwave feed port 13, so as to stir the microwave introduced at the first microwave feed port 12 or the second microwave feed port 13 and enhance the dispersion degree of the microwave.

[0067] In some embodiments, the cooking device 100 further includes a driving member 42. The driving member 42 is installed outside the device main body 1. The driving member 42 is connected to the stirring structure 41 through a rotating shaft 43 to drive the stirring structure 41 to rotate, that is, the driving member 42 and the stirring structure 41 are respectively located outside and inside the cooking cavity 11, so that the driving member 42 can drive the stirring structure 41 to perform microwave stirring through the rotating shaft 43 penetrating the device main body 1.

[0068] Therefore, the driving member 42 does not need to occupy the space inside the cooking cavity 11, increasing the available space inside the cooking cavity 11 and facilitating the increase of the capacity of the cooking cavity 11.

[0069] Among them, the driving member 42 can be configured as a driving motor. The motor shaft of the driving motor can be fixedly connected to the rotating shaft 43, so that when the driving motor outputs power, the motor shaft can drive the rotating shaft 43 to rotate, and then drive the stirring structure 41 to rotate through the rotating shaft 43. And, in the specific design, the stirring structure 41 can be configured as a plate-shaped member, such as configuring the stirring structure 41 as a circular plate, and the center of the circular plate is fixedly connected to the end of the rotating shaft 43 away from the driving member 42, so that when the rotating shaft 43 rotates, it can drive the circular plate to rotate, and then play a role in stirring and dispersing the microwave during the rotation process, enhancing the uniform effect of the microwave in the cooking cavity 11.

[0070] In some embodiments, the rotating shaft 43 extends along a first direction. The first direction may be the up-and-down direction, that is, the rotating shaft 43 can be arranged to extend along the up-and-down direction. That is to say, the rotating shaft 43 can be arranged to penetrate the bottom wall of the cooking cavity 11 along the up-and-down direction, and the upper end of the rotating shaft 43 extends into the cooking cavity 11 and is connected to the stirring structure 41, and the lower end of the rotating shaft 43 extends below the cooking cavity 11 and is connected to the motor shaft of the driving motor to transmit power between the driving motor and the stirring structure 41.

[0071] Specifically, as Figure 5 and Figure 6 shown, a first through hole 14 can be provided in the bottom wall of the cooking cavity 11, and the rotating shaft 43 can penetrate the bottom wall of the cooking cavity 11 from the first through hole 14 to achieve the through-fit with the equipment body.

[0072] In some embodiments, the rotating shaft 43 penetrates the waveguide channel, that is, the rotating shaft 43 can be integrally installed with the waveguide component to realize the spatial sharing of the rotating shaft 43 and the waveguide component, achieve compact installation, and reduce the overall volume of the cooking device 100.

[0073] Specifically, as Figure 1 shown, the first waveguide part 211 is located at the bottom of the cooking cavity 11, and the driving motor is located below the first waveguide part 211. The rotating shaft 43 penetrates the first waveguide part 211 to extend into the cooking cavity 11. As Figure 5 and Figure 6 shown, a second through hole 214 is provided in the bottom wall of the first waveguide part 211. The rotating shaft 43 can be sequentially passed through the second through hole 214 and the first through hole 14 to penetrate the first waveguide part 211 to achieve integrated installation and increase the space utilization rate.

[0074] Moreover, in some embodiments, the cooking cavity 11 is provided with a plurality of first microwave feeding ports 12, and the plurality of first microwave feeding ports 12 are distributed around the rotating shaft 43. The first microwave feeding ports 12 are provided on the bottom wall of the cooking cavity 11, and the plurality of first microwave feeding ports 12 are all directly opposite and communicated with the first waveguide part 211. Thus, when the microwave at the first waveguide part 211 enters the cooking cavity 11 through the plurality of first microwave feeding ports 12, the microwaves at the plurality of first microwave feeding ports 12 can be conducted toward the stirring structure 41 connected to the rotating shaft 43. Furthermore, the microwaves introduced at the plurality of first microwave feeding ports 12 can be stirred by the stirring structure 41 to effectively disperse the microwaves, which is beneficial to improving the microwave uniformity in the cooking cavity 11.

[0075] In some embodiments, the waveguide assembly is provided with a mounting portion 223, the driving member 42 is mounted on the mounting portion 223, and the rotating shaft 43 penetrates through the mounting portion 223 and extends into the cooking cavity 11. In this way, the integrated installation of the driving member 42 and the waveguide assembly can be realized, and no additional installation structure needs to be provided for the driving member 42, which is beneficial to reducing the setting cost and the installation difficulty.

[0076] Specifically, as Figure 5 and Figure 6 shown, the waveguide assembly includes a first waveguide 21 and a second waveguide 22. Among them, the second waveguide 22 is located at the bottom of the first waveguide 21. At the same time, the mounting portion 223 is provided on the second waveguide 22, and the driving member 42 can be detachably connected to the mounting portion 223 through a connecting member such as a bolt.
