[0037] The following reference Figures 1-7 Describe a cooking device according to an embodiment of the present invention, which has a simple structure, low setting cost, can improve light weight, reduce the overall volume of the cooking device, increase the volume of the cooking cavity 15, meet different usage requirements, and can reduce the operating energy consumption to reduce the usage cost.

[0038] As Figures 1-7 shown, a cooking device according to an embodiment of the present invention includes: a cooking housing 1, a first waveguide 2, a second waveguide 3, and a magnetron 4.

[0039] A cooking cavity 15 is formed inside a cooking housing 1. A first waveguide 2 is connected to the cooking housing 1. The first waveguide 2 is adapted to transmit microwaves into the cooking cavity 15 through the bottom wall 14 and at least one side wall 13 of the cooking housing 1. A magnetron 4 is in communication with the first waveguide 2 through a second waveguide 3, and both the second waveguide 3 and the magnetron 4 are disposed below the cooking housing 1.

[0040] Among them, this cooking device can be a microwave oven or the like, used for thawing or heating food, etc. A cooking cavity 15 is formed inside it. A space for accommodating food is formed inside the cooking cavity 15. When in use, a user can put food into the cooking cavity 15, and then can perform operations such as thawing or heating the food to meet different needs of the user.

[0041] Specifically, the cooking device is provided with a cooking housing 1. A cooking cavity 15 can be formed inside the cooking housing 1, that is, the cooking housing 1 is set as a housing structure, and the cooking cavity 15 is defined inside. A user can place food in the cooking cavity 15 to cook the food as needed. The cooking device is further provided with a first waveguide 2. The first waveguide 2 can be connected to the outer wall of the cooking housing 1 by means of welding or connectors, etc. The installation method is simple, and the first waveguide 2 is adapted to transmit microwaves into the cooking cavity 15 through the bottom wall 14 and at least one side wall 13 of the cooking housing 1, that is, the first waveguide 2 is adapted to transmit microwaves towards the bottom of the cooking cavity 15 through the bottom wall 14 of the cooking housing 1, and the first waveguide 2 is further adapted to transmit microwaves towards the side of the cooking cavity 15 through at least one side wall 13 of the cooking housing 1.

[0042] Furthermore, the first waveguide 2 is adapted to transmit microwaves towards the side of the cooking cavity 15 through at least one side wall 13 of the cooking housing 1, that is, the first waveguide 2 can be adapted to transmit microwaves towards the side of the cooking cavity 15 only through one side wall 13 of the cooking housing 1, or can be adapted to transmit microwaves towards the side of the cooking cavity 15 through two or three side walls 13 of the cooking housing 1, etc. The first waveguide 2 can also be adapted to transmit microwaves towards the bottom of the cooking cavity 15 through the bottom wall 14 of the cooking housing 1. Thus, the microwaves transmitted into the first waveguide 2 can be transmitted towards multiple positions such as the bottom and side of the cooking cavity 15 through the first waveguide 2, which can improve the uniformity of cooking food in the cooking cavity 15, further improve the user experience, reduce the setting of driving parts, etc., reduce the setting cost, and can reduce the operating energy consumption to reduce the use cost.

[0043] In addition, the cooking device is further provided with a second waveguide 3 and a magnetron 4. The second waveguide 3 can be connected to the first waveguide 2 by welding or integrally formed, and the second waveguide 3 is communicated with the first waveguide 2, so that the microwave in the second waveguide 3 can be transported into the first waveguide 2. The magnetron 4 is communicated with the second waveguide 3. The magnetron 4 can be connected to the first waveguide 2 or the second waveguide 3 through a connecting piece or the like. The magnetron 4 can also be respectively connected to both the first waveguide 2 and the second waveguide 3 through a connecting piece or the like to ensure the installation reliability. And the magnetron 4 can transport microwave into the second waveguide 3 to be transported into the first waveguide 2 through the second waveguide 3, and then can transport the microwave toward multiple places in the cooking cavity 15 through the first waveguide 2 to ensure the cooking reliability.

[0044] Moreover, both the second waveguide 3 and the magnetron 4 are arranged below the cooking housing 1, that is, the first waveguide 2 is located above the second waveguide 3 and the magnetron 4. The magnetron 4 can transport the microwave into the second waveguide 3, and the second waveguide 3 can transport the microwave upward into the first waveguide 2. Then, the microwave can be transported toward the bottom and the side of the cooking cavity 15 respectively through the first waveguide 2, which can reduce the space occupied by both sides of the cooking housing 1. Furthermore, the weight of the cooking device can be reduced, the overall volume of the cooking device can be reduced, the volume of the cooking cavity 15 can be increased, and different usage requirements can be met.

[0045] For the cooking device according to the embodiment of the present invention, by arranging the magnetron 4 below the cooking housing 1 and transporting the microwave into the cooking cavity 15 through the second waveguide 3 and the first waveguide 2 in sequence, the weight of the cooking device can be reduced while ensuring the cooking uniformity, the overall volume of the cooking device can be reduced, the volume of the cooking cavity 15 can be increased, different usage requirements can be met, the structure is simple, the setting cost is low, the operation energy consumption can be reduced to reduce the usage cost, the usage effect is better, and the applicable range is wider.

[0046] In some embodiments, the magnetron 4 and the second waveguide 3 are distributed horizontally below the cooking housing 1.

[0047] Specifically, as Figures 2-4 shown, both the magnetron 4 and the second waveguide 3 are arranged below the cooking housing 1, and both the magnetron 4 and the second waveguide 3 are located below the first waveguide 2. The magnetron 4 is communicated with the second waveguide 3, and the second waveguide 3 is communicated with the first waveguide 2, so that the magnetron 4 can be communicated with the first waveguide 2 through the second waveguide 3 to transport the microwave into the cooking cavity 15 through the first waveguide 2.

[0048] Moreover, the magnetron 4 and the second waveguide 3 are horizontally distributed below the cooking housing 1, that is, the magnetron 4 and the second waveguide 3 are located in the same plane. Among them, the magnetron 4 and the second waveguide 3 can be sequentially distributed in the left-right direction, the front-back direction, or the diagonal direction in the horizontal direction, etc. The setting direction is flexible, which is convenient for the magnetron 4 and the second waveguide 3 to be connected in the horizontal direction, can shorten the setting length of the second waveguide 3 in the horizontal direction, and then can reduce the space occupied by the magnetron 4 and the second waveguide 3, so as to reduce the overall volume of the cooking device and increase the volume of the cooking cavity 15 to meet different usage requirements.

[0049] In some embodiments, the magnetron 4 and the second waveguide 3 are distributed in the left-right direction below the cooking housing 1.

[0050] Specifically, both the magnetron 4 and the second waveguide 3 are arranged below the cooking housing 1, and both the magnetron 4 and the second waveguide 3 are located below the first waveguide 2. As Figures 2-4 shown, the magnetron 4 and the second waveguide 3 are distributed in the left-right direction below the cooking housing 1. That is, the magnetron 4 can be arranged on the left side below the first waveguide 2, and the second waveguide 3 can be arranged on the right side below the first waveguide 2. It is also possible to arrange the magnetron 4 on the right side below the first waveguide 2, and the second waveguide 3 can be arranged on the left side below the first waveguide 2. This can make full use of the space below the first waveguide 2 and also improve the space utilization rate of the area below the cooking housing 1, so as to reduce the overall volume of the cooking device and increase the volume of the cooking cavity 15 to meet different usage requirements.

[0051] In some embodiments, the second waveguide 3 is formed with a first communication port 31 and a second communication port 32. The first communication port 31 is formed at the top of the second waveguide 3 and communicates with the first waveguide 2, and the second communication port 32 is formed on the side wall 13 of the second waveguide 3. The magnetron 4 communicates with the second communication port 32.

[0052] Specifically, the magnetron 4 can be connected to the first waveguide 2 through the second waveguide 3. And as Figures 1-2 shown, the second waveguide 3 is provided with a first communication port 31 and a second communication port 32. The second waveguide 3 can be connected to the first waveguide 2 through the first communication port 31, and the magnetron 4 can be connected to the second waveguide 3 through the second communication port 32. Thus, the magnetron 4 can be connected to the first waveguide 2 through the second waveguide 3, so that the magnetron 4 can transmit microwaves to the first waveguide 2 through the second waveguide 3, and then can transmit microwaves to multiple places in the cooking cavity 15 through the first waveguide 2, improving the cooking uniformity.

[0053] Further, the first communication port 31 is formed at the top of the second waveguide 3, and the second communication port 32 is formed at the side wall 13 of the second waveguide 3. That is, the magnetron 4 communicates with the side wall 13 of the second waveguide 3, and the first waveguide 2 communicates with the top of the second waveguide 3. This enables the magnetron 4 to transmit microwaves into the second waveguide 3 from the side wall 13 of the second waveguide 3. The microwaves are then redirected inside the second waveguide 3 and transported upward to the first communication port 31, and then upward through the first communication port 31 into the first waveguide 2. Thus, the magnetron 4 can be arranged horizontally and can be disposed below the first waveguide 2, which can improve the utilization rate of the space below the cooking housing 1, reduce the overall volume of the cooking device, increase the volume of the cooking cavity 15, and meet different usage requirements.

[0054] In some embodiments, the first waveguide 2 includes a first sub-tube 21 and at least one second sub-tube 22. The first sub-tube 21 and the at least one second sub-tube 22 are in communication. Among them, the first sub-tube 21 is connected to the bottom wall 14 of the cooking housing 1, and the first sub-tube 21 is adapted to transmit microwaves into the cooking cavity 15 in the vertical direction. The at least one second sub-tube 22 is connected to the side wall 13 of at least one cooking housing 1 in a one-to-one correspondence, and the second waveguide 3 is adapted to transmit microwaves into the cooking cavity 15 in the horizontal direction.

[0055] Specifically, the first waveguide 2 is adapted to transmit microwaves into the cooking cavity 15 through the bottom wall 14 and at least one side wall 13 of the cooking housing 1, and as Figures 1-6 shown, the first waveguide 2 includes a first sub-tube 21 and a second sub-tube 22. The second sub-tube 22 is provided as at least one, that is, the second sub-tube 22 can be provided as one as Figure 6 shown, or can be provided as two as Figures 1-2 shown, etc. The at least one second sub-tube 22 is communicatively connected to the first sub-tube 21. That is, when the second sub-tube 22 is provided as one, one second sub-tube 22 is communicatively connected to the first sub-tube 21. When the second sub-tube 22 is provided as two, the two second sub-tubes 22 are respectively communicatively connected to the first sub-tube 21. Thus, microwaves can flow from the first sub-tube 21 into the at least one second sub-tube 22.

[0056] Further, the first sub-tube 21 is connected to the bottom wall 14 of the cooking housing 1, and the first sub-tube 21 is adapted to transmit microwaves into the cooking cavity 15 in the vertical direction. Both the magnetron 4 and the second waveguide 3 are located below the cooking cavity 15. That is, the magnetron 4 is communicatively connected to the first sub-tube 21 through the second waveguide 3. The magnetron 4 is located below the first sub-tube 21, so that the microwaves in the second waveguide 3 can be transmitted upward into the first sub-tube 21, and a part of the microwaves in the first sub-tube 21 can continue to be transmitted upward to be transmitted into the cooking cavity 15.

[0057] In addition, at least one second sub-tube 22 is connected to the side wall 13 of at least one cooking housing 1 in a one-to-one correspondence, and the second waveguide 3 is adapted to convey microwaves horizontally into the cooking cavity 15. That is, when there is one second sub-tube 22, one second sub-tube 22 can be connected to the side wall 13 of one cooking housing 1. When there are two second sub-tubes 22, the two second sub-tubes 22 can be respectively connected to the side walls 13 of two cooking housings 1, and so on, so that at least one second sub-tube 22 can convey microwaves horizontally into the cooking cavity 15.

[0058] In this way, the first sub-tube 21 can convey microwaves upward into the cooking cavity 15 at the bottom of the cooking cavity 15, and the second sub-tube 22 can convey microwaves horizontally into the cooking cavity 15 at the side of the cooking cavity 15. Furthermore, the first sub-tube 21 and the second sub-tube 22 can convey microwaves into the cooking cavity 15 from different directions respectively, so as to heat the food in the cooking cavity 15 from multiple directions, improve cooking uniformity, and only one first waveguide 2 needs to be provided, which can reduce the setting cost, improve the compactness of the cooking device, and reduce the overall volume of the cooking device.

[0059] In some embodiments, at least one first feeding port 11 is formed on the bottom wall 14 of the cooking housing 1, and the first sub-tube 21 communicates with at least one first feeding port 11.

[0060] Specifically, the first sub-tube 21 is adapted to convey microwaves toward the bottom of the cooking cavity 15, and as Figure 1 shown, the upper direction of the first sub-tube 21 is open upward to form a third communication port 211, and at least one first feeding port 11 is formed on the bottom wall 14 of the cooking housing 1. That is, the first feeding port 11 can be set to one, two or more, etc. The third communication port 211 is connected to at least one first feeding port 11, so that the microwaves in the first sub-tube 21 can be conveyed to at least one first feeding port 11 through the third communication port 211, and the microwaves can flow through at least one first feeding port 11 to the bottom of the cooking cavity 15. Furthermore, microwaves can be conveyed to the bottom of the cooking cavity 15 through the first sub-tube 21. When there are multiple first feeding ports 11, the third communication port 211 can be respectively connected to multiple first feeding ports 11, and further microwaves can be conveyed to the bottom of the cooking cavity 15 through multiple first feeding ports 11, improving cooking uniformity.

[0061] Wherein, a mica sheet or a glass cover plate and other structures can be provided at the first feeding port 11 to seal the first feeding port 11, and the microwaves in the first sub-tube 21 can still be conveyed into the cooking cavity 15, ensuring cooking reliability while avoiding food in the cooking cavity 15 from splashing into the first sub-tube 21, improving cleaning convenience and ensuring microwave transmission reliability.

[0062] In some other embodiments, a second feed port 12 is formed in the side wall 13 of the cooking housing 1, and the second sub-tube 22 communicates with the second feed port 12.

[0063] Specifically, the second sub-tube 22 is adapted to convey microwaves towards the side of the cooking cavity 15, and as Figure 1 shown, one side of the second sub-tube 22 close to the cooking housing 1 is open to form a fourth communication port 221, and a second feed port 12 is formed in the side wall 13 of the cooking housing 1. The fourth communication port 221 is connected to the second feed port 12, so that the microwaves in the second sub-tube 22 can be conveyed to the second feed port 12 through the fourth communication port 221, and the microwaves can flow through the second feed port 12 to the side of the cooking cavity 15. Furthermore, microwaves can be conveyed to the side of the cooking cavity 15 through the second sub-tube 22. In actual setting, the second feed port 12 can also be set to be multiple, so that the fourth communication port 221 communicates with multiple second feed ports 12. Furthermore, microwaves can be respectively conveyed to the side of the cooking cavity 15 through multiple second feed ports 12, improving cooking uniformity.

[0064] Wherein, a mica sheet or a glass cover plate and other structures can be arranged at the second feed port 12, which can seal the second feed port 12, and the microwaves in the second sub-tube 22 can still be conveyed into the cooking cavity 15, ensuring cooking reliability while avoiding food in the cooking cavity 15 from splashing into the second sub-tube 22, improving cleaning convenience and ensuring microwave conveyance reliability.

[0065] In some embodiments, multiple first feed ports 11 are provided, and the multiple first feed ports 11 are spaced apart and distributed on the bottom wall 14 of the cooking housing 1, and the first sub-tubes 21 communicate with the multiple first feed ports 11 respectively.

[0066] Specifically, the upper part of the first sub-tube 21 is open upwards to form a third communication port 211, and the third communication port 211 is connected to the first feed port 11 to convey microwaves to the bottom of the cooking cavity 15 through the first feed port 11, and as Figures 1-3 shown, the first feed port 11 can be set to be multiple, and the multiple first feed ports 11 are spaced apart and distributed on the bottom wall 14 of the cooking housing 1. The shapes of the multiple first feed ports 11 can be set to be the same or different, and the multiple first feed ports 11 can be Figure 1 spaced apart in a ring shape as shown. In actual setting, the multiple first feed ports 11 can also be arranged in a matrix, etc., and the setting method is flexible.

[0067] Further, the first sub-tube 21 can be arranged to communicate with a plurality of first feeding ports 11 respectively, that is, the third communication port 211 of the first sub-tube 21 can be arranged to communicate with a plurality of first feeding ports 11 respectively. In the vertical direction, a plurality of first feeding ports 11 are all within the opening range of the third communication port 211. Thus, the first sub-tube 21 can convey microwaves to a plurality of first feeding ports 11 through one third communication port 211. The plurality of first feeding ports 11 can disperse the microwaves conveyed to the third communication port 211, so that the plurality of first feeding ports 11 can respectively convey microwaves to multiple places at the bottom of the cooking cavity 15 to jointly heat multiple places of the food. The structure is simple and the cooking uniformity can be improved.

[0068] In some embodiments, at least a part of the plurality of first feeding ports 11 are configured as arc-shaped feeding ports, and at least two first feeding ports 11 are distributed around the center of the bottom wall 14 of the cooking housing 1.

[0069] Specifically, a plurality of first feeding ports 11 are provided, and at least a part of the plurality of first feeding ports 11 are configured as arc-shaped feeding ports. That is, part of the plurality of first feeding ports 11 can be set as arc-shaped feeding ports, or all of the plurality of first feeding ports 11 can be set as arc-shaped feeding ports. Setting the first feeding ports 11 as arc-shaped feeding ports can increase the extension range of the first feeding ports 11, thereby improving the cooking effect on the food. And a reinforcing flange is provided at the edge of the first feeding port 11, which can improve the structural strength of the bottom wall 14 of the cooking housing 1 and ensure the reliability of use.

[0070] And at least two first feeding ports 11 are distributed around the center of the bottom wall 14 of the cooking housing 1, that is, microwaves can be conveyed towards the center of the bottom wall 14 of the cooking housing 1 through at least two first feeding ports 11, thereby ensuring the uniformity of cooking the bottom of the food and improving the cooking effect.

[0071] In some embodiments, two second sub-tubes 22 are provided. The two second sub-tubes 22 are respectively communicated with two ends of the first sub-tube 21, and the two second sub-tubes 22 are respectively connected to two opposite side walls 13 of the cooking housing 1.

[0072] Specifically, the second sub-tube 22 is communicated with the first sub-tube 21, so that the first sub-tube 21 can convey microwaves to the second sub-tube 22. And as Figures 1-3 shown, two second sub-tubes 22 are provided. The two second sub-tubes 22 are both communicated with the first sub-tube 21, so that the microwaves in the first sub-tube 21 can be respectively conveyed to the two second sub-tubes 22. And the second sub-tube 22 is connected to the side wall 13 of the cooking housing 1, so that the second sub-tube 22 can convey microwaves into the cooking cavity 15 in the horizontal direction.

[0073] Further, both of the two second sub-tubes 22 can be connected to the side wall 13 of the cooking housing 1, and the two second sub-tubes 22 are respectively connected to two side walls 13 of the cooking housing 1 that are oppositely distributed, that is, the two second sub-tubes 22 can be respectively located on both sides of the cooking housing 1 to simultaneously transmit microwaves to both sides of the cooking cavity 15, so as to heat the food in all directions.

[0074] In actual setting, the second sub-tube 22 can also extend upward to communicate with the top wall of the cooking housing 1, or three second sub-tubes 22 can be provided, so that the three second sub-tubes 22 can be respectively connected to the respective side walls 13 of the cooking housing 1. The setting method is flexible, and the food can be heated from all directions, improving the cooking uniformity and the cooking speed.

[0075] In some embodiments, the projection of at least one first feed port 11 in the vertical direction is located in the middle of the first sub-tube 21 along the length direction.

[0076] Specifically, a plurality of first feed ports 11 are provided, and as Figure 1 shown, the projection of at least one of the plurality of first feed ports 11 in the vertical direction is located in the middle of the first sub-tube 21 along the length direction. The first sub-tube 21 can be arranged to extend in the left-right direction, and the first sub-tube 21 is installed in the middle of the cooking housing 1 along the front-rear direction, so that at least one first feed port 11 can be located in the middle of the cooking cavity 15, so that the microwaves in the first sub-tube 21 can be evenly transmitted upward from the bottom of the cooking cavity 15 to ensure cooking uniformity.

[0077] In some other embodiments, the two second sub-tubes 22 are symmetrically distributed at both ends of the first sub-tube 21.

[0078] Specifically, two second sub-tubes 22 can be provided. The two second sub-tubes 22 are respectively communicated with both ends of the first sub-tube 21, so that the first sub-tube 21 can transmit microwaves to the two second sub-tubes 22 respectively. And as Figures 1-2 shown, the two second sub-tubes 22 are symmetrically distributed at both ends of the first sub-tube 21, that is, the amount of microwaves transmitted by the first sub-tube 21 to the two second sub-tubes 22 is equal. Thus, it can be ensured that the amount of microwaves transmitted from both sides of the cooking cavity 15 into the cooking cavity 15 by the two second sub-tubes 22 is equal, so as to ensure the uniformity of side heating of the food, ensure the cooking effect, and improve the use experience.

[0079] In some embodiments, the total opening area of the first feed port 11 is set to be larger than the total opening area of the second feed port 12.

[0080] Specifically, a plurality of first feed ports 11 may be provided. The plurality of first feed ports 11 are spaced apart and distributed on the bottom wall 14 of the cooking housing 1. A second feed port 12 is provided on the side wall 13 of the cooking housing 1, and the second feed port 12 may be provided on each of the plurality of side walls 13 of the cooking housing 1. The total opening area of the plurality of first feed ports 11 is set to be larger than the total opening area of the plurality of second feed ports 12, that is, the amount of microwave delivered to the bottom of the cooking cavity 15 from the first sub-tube 21 is greater than the amount of microwave delivered to the side of the cooking cavity 15 from the second sub-tube 22.

[0081] Further, the magnetron 4 may deliver microwave to the first sub-tube 21 through the second waveguide 3. A part of the microwave in the first sub-tube 21 may be directly delivered into the cooking cavity 15 from the bottom of the cooking cavity 15, and another part of the microwave in the first sub-tube 21 may be delivered to the second sub-tube 22, and then delivered into the cooking cavity 15 from the side of the cooking cavity 15 through the second sub-tube 22. The area of the bottom wall 14 of the cooking housing 1 is set to be relatively large, which can increase the food volume. And setting the total opening area of the first feed ports 11 to be larger than the total opening area of the second feed ports 12 can deliver microwave to a larger area at the bottom of the food, thereby ensuring the cooking effect on the food.

[0082] In some embodiments, the total opening area of the first feed ports 11 is set to a, and the total opening area of the second feed ports 12 is set to b, and they satisfy: a / b = 2.

[0083] Specifically, the total opening area of the first feed ports 11 may be set to a, and the total opening area of the second feed ports 12 may be set to b, and they satisfy: a / b = 2, that is, the total opening area of the first feed ports 11 is set to be larger than the total opening area of the second feed ports 12. In actual setting, the total opening area of the first feed ports 11 may be set to account for 2 / 3 of the total opening area of all feed ports, the opening area of the second feed port 12 on the left side may be set to account for 1 / 6 of the total opening area of all feed ports, and the opening area of the second feed port 12 on the right side may be set to account for 1 / 6 of the total opening area of all feed ports. Thus, the microwave can be fed into the cooking cavity 15 from different directions to form a uniform field by superposition, improving the cooking uniformity.

[0084] In some embodiments, the cooking device further includes a device housing. The cooking housing 1 is located inside the device housing. The device housing includes a door body and a housing main body. The housing main body forms an activity opening. The door body is movably installed at the activity opening to open or close the activity opening. The cooking cavity 15 is communicated with the activity opening.

[0085] Specifically, the cooking device is further provided with a device housing. Structures such as the cooking housing 1, the first waveguide 2, the second waveguide 3, and the magnetron 4 are all installed inside the device housing. The device housing is provided with a door body and a housing main body. An activity opening is formed on one side of the housing main body. The activity opening can be arranged at the front side of the cooking device for the convenience of user operation. The door body is rotatably installed at the activity opening to open or close the activity opening. The cooking cavity 15 is communicated with the activity opening. When the user needs to place food into the cooking cavity 15, the user can pull the door body to rotate the door body relative to the housing main body to open the activity opening, so that the user can place food into the cooking cavity 15 from the activity opening. And when the cooking device is idle or cooking, the door body can be closed to the activity opening to ensure the sealing of the cooking cavity 15, prevent dust from flowing into the cooking cavity 15, and also prevent the high-temperature gas generated during the cooking process from burning the user, etc., thereby improving the use safety.
