Description

Technical Field

[0001] This utility model relates to a cooking device. Background Technology

[0002] With the increasing demands of modern families for kitchen appliances, heating efficiency and uniformity have become key concerns for users of cooking equipment such as microwave ovens and steam ovens. Traditional cooking equipment generally uses a single magnetron as the microwave source, guiding microwaves into the oven cavity through a single waveguide to heat food. However, due to the limited power and microwave radiation range of a single magnetron, uneven microwave distribution within the oven cavity is often observed, especially when heating larger or irregularly shaped foods, resulting in significant differences in heating across different parts of the food and affecting the heating effect. Therefore, dual-magnetron cooking equipment has emerged and has gradually become a representative of high-end cooking equipment.

[0003] Dual magnetron cooking appliances generate and amplify microwave energy by having two independent magnetron systems operate simultaneously or alternately. These microwaves are transmitted to the oven cavity via a waveguide system to heat the food, resulting in a significantly increased overall heat dissipation load. Traditional heat dissipation designs may not be able to meet the heat dissipation requirements of a dual magnetron system, thus affecting the stable operation and lifespan of the appliance.

[0004] To address the heat dissipation issue in dual magnetron cooking equipment, the applicant submitted several patent applications during its early research phase, including CN202422321924.3, CN202411329260.3, CN202422321801.X, and CN202422321754.9. These patents disclosed the installation of a dual magnetron system below the oven cavity (corresponding to the base position) of the cooking equipment, along with a corresponding air duct structure, allowing the heat dissipation airflow to be exhausted from the air outlet located on the rear side of the base.

[0005] However, the applicant found in subsequent research that users often place the back of the cooking equipment close to the wall when placing it. This causes the heat dissipation airflow from the back of the base to flow directly towards the wall. Since the space between the back of the cooking equipment and the wall is relatively small, the heat dissipation airflow has difficulty flowing out (diffusing) in time, resulting in heat accumulation and airflow obstruction, which leads to poor actual heat dissipation.

[0018] Compared with the prior art, the cooking device of this utility model has the following advantages:

[0019] Compared with the prior art, the cooking device of this utility model, by additionally setting a rear air duct, allows the heat dissipation airflow passing through the magnetron and frequency converter to enter the corresponding channels in the rear air duct respectively, and then flow out of the rear air duct in a direction parallel to the wall. This ensures that the heat dissipation airflow exhausted by the cooking device will not flow entirely towards the wall, but can flow directly outward along the wall in a relatively smooth manner, preventing the heat dissipation airflow from accumulating in the narrow space between the rear of the cooking device and the wall. This avoids airflow obstruction, heat accumulation, and other situations, and helps the heat dissipation airflow to flow out smoothly and diffuse in a timely manner, thereby improving the heat dissipation effect.

[0031] The inventive concepts of this disclosure will be described below using terminology commonly used by those skilled in the art to convey the essence of their work to others skilled in the art. However, these inventive concepts may be embodied in many different forms and should not be construed as limited to the embodiments described herein.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other. Since the cooking equipment is sometimes shown upside down in the accompanying drawings, to avoid misunderstanding, directional terms used in this application refer to the orientation of the cooking equipment in its conventional assembly and placement state. (Refer to the accompanying drawings.) Figure 1 Appendix Figure 3 The coordinate system in the middle.

[0033] Meanwhile, to facilitate understanding of the flow direction of the cooling airflow within the corresponding channels, this application uses red arrows to indicate the flow direction of the cooling airflow through the magnetron and blue arrows to indicate the flow direction of the cooling airflow through the frequency converter, so as to make it easy to distinguish.

[0034] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] To address the problem of poor heat dissipation performance caused by the unreasonable heat dissipation structure design in existing dual magnetron cooking devices, this embodiment proposes a cooking device, as shown in the attached figure. Figure 1-8 As shown, the cooking device includes a cavity assembly. A magnetron heat dissipation structure and a frequency converter heat dissipation structure are arranged below the cavity assembly. A rear air duct 1 is arranged behind the cavity assembly. The rear air duct 1 has a first flow channel 14 and a second flow channel 15. The air outlet of the frequency converter heat dissipation structure is connected to the first flow channel 14, and the air outlet of the magnetron heat dissipation structure is connected to the second flow channel 15. The air outlet direction of the first flow channel 14 and the air outlet direction of the second flow channel 15 are both parallel to the wall directly opposite the rear side of the cooking device.

[0036] For the heat dissipation structures of the magnetron and the frequency converter, reference can be made to the applicant's earlier patents, such as CN202422321924.3, CN202411329260.3, CN202422321801.X, and CN202422321754.9, which will also be briefly introduced below. In this application, the main focus is on introducing the technical content that has significant improvements compared to the earlier patents.

[0037] Similarly, for a dual magnetron cooking device, it has two magnetron heat dissipation structures and two frequency converter heat dissipation structures. The air outlet of at least one magnetron heat dissipation structure is connected to the first flow channel 14, and the air outlet of at least one frequency converter heat dissipation structure is connected to the second flow channel 15.

[0038] Compared with the prior art, this application, by additionally setting a rear air duct 1, allows the heat dissipation airflow passing through the magnetron and inverter to enter the corresponding channels in the rear air duct 1 respectively, and then flow out of the rear air duct 1 in a direction parallel to the wall; thus, the heat dissipation airflow exhausted by the cooking equipment will not flow entirely towards the wall, but can flow directly outward along the wall in a relatively smooth manner, preventing the heat dissipation airflow from accumulating in the narrow space between the rear of the cooking equipment and the wall, avoiding airflow obstruction, heat accumulation, etc., and helping the heat dissipation airflow to flow out smoothly and diffuse in a timely manner, so as to improve the heat dissipation effect.

[0039] The cooking device includes a rear shell 104 with a rear protrusion 1041. The side wall 1044 of the rear protrusion 1041 is provided with a first air outlet 1042 and a second air outlet 1043. The first air outlet 1042 is directly opposite the air outlet of the first flow channel 14, and the second air outlet 1043 is directly opposite the air outlet of the second flow channel 15. Therefore, a rear shell 104 with a rear protrusion 1041, commonly found in conventional cooking devices, can be directly used. This allows for space avoidance for individual components inside the cooking device, and the corresponding air outlets can be directly machined using the side wall 1044 of the rear protrusion 1041, eliminating the need for additional adjustments to the air outlet direction and structure on the rear shell 104, thus achieving the desired airflow direction for heat dissipation.

[0040] Preferably, the air outlet direction of the first flow channel 14 is at least one of upward, leftward, and rightward, and the air outlet direction of the second flow channel 15 is at least one of upward, leftward, and rightward. Since cooking equipment is often placed on a supporting surface, this avoids the heat dissipation airflow flowing downward (e.g., towards the supporting tabletop), which would create unnecessary airflow obstruction. Of course, if the cooking equipment is suspended at the rear or entirely suspended, the air outlet direction can be downward.

[0041] In a preferred embodiment of this application, the air outlet of the first flow channel 14 faces upward and is designated as the upper air outlet 12, while the air outlet of the second flow channel 15 faces left or right and is designated as the side air outlet 13. Correspondingly, the rear shell 104 can have air outlet holes formed at corresponding positions on the side wall 1044.

[0042] The rear air duct 1 has a clearance protrusion 11 for avoiding the waveguide box 105 of the cooking device, thus preventing spatial interference between components. The clearance protrusion 11 is not independent of the flow channel structure and can partially overlap with the first flow channel 14 and / or the second flow channel 15 in terms of structure. The flow channel wall shape of the corresponding flow channel can be appropriately adjusted to form spatial clearance for the waveguide box 105. Correspondingly, the cooking device includes a stirring motor 1051, which cooperates with the waveguide box 105, stirring plate (not shown), and other structures. The existing technology can be referenced. This application does not elaborate on the microwave conduction structure and stirring structure.

[0043] The stirring motor 1051 is disposed in the first flow channel 14 or the second flow channel 15, and the rear air duct 1 is provided with a clearance portion 111 corresponding to the stirring motor 1051. Thus, in the process of discharging the cooling airflow from the magnetron or the inverter, the cooling airflow also flows through the stirring motor 1051 to dissipate heat, thus improving the overall heat dissipation effect of the cooking equipment. Preferably, the clearance portion 111 is a clearance opening structure, and the clearance portion 111 is positioned near the air outlet of the first flow channel 14 or near the air outlet of the second flow channel 15 to ensure the normal flow and discharge of the cooling airflow.

[0044] In this application, the two magnetrons are referred to as the first magnetron 4 and the second magnetron 6, respectively, and the two frequency converters are referred to as the first frequency converter 5 and the second frequency converter 7, respectively; the air outlets of the heat dissipation structures of the two magnetrons can be connected to the first flow channel 14, and the air outlets of the heat dissipation structures of the two frequency converters can be connected to the second flow channel 15.

[0045] However, considering the structural setup, spatial allocation, overall machine and component dimensions, this application retains the applicant's earlier heat dissipation channel (air duct) structure for the heat dissipation structure related to the first magnetron 4 and the first frequency converter 5; and mainly coordinates the heat dissipation structure related to the second magnetron 6 and the second frequency converter 7 with the rear air duct 1.

[0046] For details regarding the heat dissipation structure of the first magnetron 4 and the first frequency converter 5, please refer to the applicant's earlier patents.

[0047] Simply put:

[0048] The cooking device includes a base 103, and at least one of the rear side wall, left side wall, right side wall and bottom wall of the base 103 is provided with a heat dissipation vent 1031;

[0049] A first fan 41 is provided on the air inlet side of the first magnetron 4, and a first air guide 42 is provided on the air outlet side of the first magnetron 4. A first air outlet 43 is provided at the end of the first air guide 42 away from the first magnetron 4, and the first air outlet 43 can be connected to the heat dissipation air outlet 1031.

[0050] The first frequency converter 5 is disposed in the second lower air duct 3. A second fan 51 is disposed on the air inlet side of the second lower air duct 3, and a second exhaust port 33 is disposed on the air outlet side of the second lower air duct 3. The second exhaust port 33 can communicate with the heat dissipation air outlet 1031. Correspondingly, the second lower air duct 3 is assembled from a second lower housing 31 and a second upper housing 32, which is consistent with the applicant's earlier patent and will not be described in detail.

[0051] Regarding the heat dissipation structure related to the second magnetron 6 and the second frequency converter 7, the details are as follows:

[0052] The magnetron heat dissipation structure includes a third fan 61, a second magnetron 6, and a second air guide 62. The air outlet side of the third fan 61 is connected to the air inlet side of the second magnetron 6. The second air guide 62 is provided on the air outlet side of the second magnetron 6. A second air outlet 63 is provided at the end of the second air guide 62 away from the second magnetron 6. The second air outlet 63 is connected to the second flow channel 15. Specifically, the second air outlet 63 is connected to or connected to the second air inlet end 151 of the second flow channel 15, thereby realizing the combination between the heat dissipation structure of the second magnetron 6 and the rear air channel 1.

[0053] The inverter heat dissipation structure includes a second inverter 7, a first lower air duct 2, and a fourth fan 71. The second inverter 7 is disposed inside the first lower air duct 2. The fourth fan 71 is disposed on the side of the first lower air duct 2 away from the rear air duct 1. A first exhaust port 23 is disposed on the side of the first lower air duct 2 close to the rear air duct 1. The first exhaust port 23 is connected to the first flow channel 14. Specifically, the first exhaust port 23 is connected to or connected to the first air inlet 141 of the first flow channel 14, thereby realizing the combination of the heat dissipation structure of the second inverter 7 and the rear air duct 1.

[0054] The fourth fan 71 can be fixed outside or inside the first downdraft duct 2, and this application does not impose any restrictions. Preferably, a fan mounting position 25 is provided inside the first downdraft duct 2, and the fourth fan 71 can be installed in the fan mounting position 25.

[0055] Considering the comprehensive requirements for the size of the fan's suction space and the space constraints for component placement, compared to the applicant's earlier patents, such as CN202411329260.3, it can be seen that the fan corresponding to the third fan 61 in this application is set in the slit between the magnetron and the air duct structure. This makes it difficult for the fan to have enough suction space even when it is operating under overload, making it difficult to draw in enough air and ensuring the flow rate of its heat dissipation airflow.

[0056] Therefore, this application makes certain improvements to the first downdraft duct 2, ensuring smooth airflow for heat dissipation while maximizing the suction side space of the fan to increase the airflow rate for heat dissipation. Specifically:

[0057] The first downdraft duct 2 includes a first duct cavity 20, the second frequency converter 7 is disposed in the first duct cavity 20, the fourth fan 71 is disposed on the side of the first duct cavity 20 away from the rear duct 1, and the first exhaust port 23 is disposed on the side of the first duct cavity 20 close to the rear duct 1.

[0058] The first lower air duct 2 has a second air duct cavity 24 on the side of the first air duct cavity 20 near the second magnetron 6. The first air duct cavity 20 and the second air duct cavity 24 are independent air duct structures. In the field of mechanical design, this can be achieved by simply setting a partition plate between the first air duct cavity 20 and the second air duct cavity 24, making them spatially independent. This will not be elaborated further.

[0059] The air inlet 241 of the second air duct cavity 24 is connected to or connected to the air outlet side of the third fan 61, and the air outlet 242 of the second air duct cavity 24 is connected to or connected to the air inlet side of the second magnetron 6. Thus, without affecting the heat dissipation of the second inverter 7, by additionally providing the second air duct cavity 24 in the slit between the magnetron and the air duct structure, the third fan 61 can be moved out of this slit, giving the third fan 61 a larger suction space, which helps to increase the flow rate of the cooling air and further improve the heat dissipation effect. Preferably, the second air duct cavity 24 has a smoothly transitioned space, allowing airflow to flow smoothly through the second air duct cavity 24.

[0060] Accordingly, for each fan in this application, axial flow fans, cross flow fans, centrifugal fans, etc. can be selected according to the actual fan size, the location of the air intake space, and the size of the space, without going into details.

[0061] The first lower air duct 2 is also assembled from the first lower shell 21 and the first upper shell 22, similar to the assembly of the second lower air duct 3. The difference is that after the first lower shell 21 and the first upper shell 22 are assembled, the first air duct cavity 20 and the second air duct cavity 24 will be formed directly.

[0062] For the first frequency converter 5, in addition to the frequency converter body, a heat sink 72 is often installed. The heat sink 72 is often close to the frequency converter body. In order to avoid the heat sink 72 affecting the frequency converter body, a partition 26 is installed in the first air duct cavity 20. The partition 26 is placed between the frequency converter body and the heat sink 72 so that the heat dissipation of the two do not interfere with each other as much as possible. The partition 26 is integrally formed with the first lower housing 21 or the first upper housing 22.

[0063] In this utility model, the technical content described in this embodiment can be adopted for any cooking device, such as a microwave oven or a steam oven. Based on the relevant structure and assembly relationship provided in this application, the cooking device also includes conventional components such as a door 101, a U-shaped outer shell 102, a cavity structure, and an electrical control component 106. Since these conventional components can all adopt existing technology, they will not be described in detail here.

[0064] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
