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 appliances, the applicant conducted research and submitted a Chinese patent (publication number CN119063036A), which includes a furnace cavity assembly. Below the furnace cavity assembly are a first magnetron, a first frequency converter, a second magnetron, and a second frequency converter connected together. The first magnetron is connected to the first frequency converter, and the second frequency converter is connected to the second magnetron. The first and second frequency converters are located at the rear ends of both sides of the furnace cavity assembly. The first frequency converter is housed within a first air duct, and the second frequency converter is housed within a second air duct. Air supply devices are installed in both the first and second air ducts to drive airflow. This solution can effectively expel hot air in a timely manner to prevent heat accumulation. However, because one side of the related structure is in direct contact with the base, a gap exists between them, which can easily generate noise. Furthermore, if hot air re-enters the fan through the gap, it will affect the heat dissipation performance.

[0005] In view of the above, this utility model is hereby proposed. Utility Model Content

Detailed Implementation

[0033] 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.

[0034] 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.

[0035] 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.

[0036] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] Example 1

[0038] like Figure 1-10 As shown, a cooking device includes a base 103, a cavity assembly is disposed above the base 103, an air inlet structure is disposed on the front side of the base 103, and a first magnetron 4, a second magnetron 6, and an electrical control structure 106 are disposed below the cavity assembly. The first magnetron 4 and the second magnetron 6 respectively transmit microwaves inward from the bottom and rear of the cavity assembly. A first heat dissipation structure is disposed on the side of the first magnetron 4, and a second heat dissipation structure is disposed on the side of the second magnetron 6. The electrical control structure 106 is disposed between the inlet end of the first heat dissipation structure and / or the second heat dissipation structure and the air inlet structure.

[0039] The microwave oven described in this application can dissipate heat from two microwave generating devices by setting a first heat dissipation structure and a second heat dissipation structure, thus balancing the heating efficiency and heat dissipation performance of the microwave oven. At the same time, the electronic control structure 106 is set between the air inlet structure and the inlet end of the first or second heat dissipation structure 106. While the first or second heat dissipation structure dissipates heat from the microwave generating devices, it drives the outside air to enter and flow through the electronic control structure 106 first, thereby making the operation of the electronic control structure 106 stable and reliable and extending its service life.

[0040] Preferably, the first heat dissipation structure and the second heat dissipation structure are provided with a sponge 100 on the side near the base 103. The sponge 100 cooperates with the first heat dissipation structure and the second heat dissipation structure to form an air intake space, and the electronic control structure 106 is located in the air intake space.

[0041] This design enables flexible contact between the first and second heat dissipation structures and the base 103, achieving a vibration reduction and isolation effect. At the same time, the sponge component 100 provides a sealing effect, allowing air to flow through the preset air duct, resulting in good heat dissipation for the components.

[0042] Preferably, the sponge component 100 is heat-insulating cotton and is composed of multiple line segments. This arrangement allows the sponge component 100 to utilize the existing structures of the first and second heat dissipation structures, resulting in high space utilization. The sponge component 100 can also be made of other elastic materials.

[0043] As an example of this utility model, 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;

[0044] The first heat dissipation structure includes a first fan 41 and a first air guide 42. The first fan 41 is disposed on the air inlet side of the first magnetron 4, and the first air guide 42 is disposed 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 communicate with the heat dissipation air outlet 1031.

[0045] Preferably, the first heat dissipation structure includes a second lower air duct 3, in which a first frequency converter 5 is disposed, the first frequency converter 5 being electrically connected to the first magnetron 4, a second fan 51 being disposed on the air inlet side of the second lower air duct 3, and a second exhaust port 33 being disposed on the air outlet side of the second lower air duct 3, the second exhaust port 33 being able to communicate with the heat dissipation air outlet 1031.

[0046] As an example of this utility model, the second lower air duct 3 is assembled from the second lower housing 31 and the second upper housing 32, which will not be described in detail.

[0047] Preferably, the second lower housing 31 is provided with a second groove 311, and a second partition 44 is provided between the second lower housing 31 and the first air guide 42. The second partition 44 includes a connected connecting plate 442 and a second folded edge 441. The second folded edge 441 extends to one side of the second lower housing 31 and at least partially covers the second groove 311.

[0048] This design can both shield the second cable tray 311 and prevent the connecting wires from coming out of the second cable tray 311 under gravity, thus providing a good wire securing effect. In addition, the second partition 44 and the first air guide 42 form a double-layer structure, and even further cooperate with the second lower housing 31 to form a triple-layer structure, thereby preventing the heat generated by the first magnetron 4 from spreading outward and affecting the operation of the first frequency converter 5, ensuring that the first frequency converter 5 operates stably and reliably.

[0049] As an example of this utility model, the second partition 44 is fixedly connected to the first air guide 42 and the second lower housing 31 respectively. This arrangement enables the first heat dissipation structure to form a whole, preventing loosening or even certain safety hazards after long-term use.

[0050] As an example of this utility model, the second fan 51 is fixed to the bottom of the furnace cavity assembly by a mounting bracket 52. The mounting bracket 52 has a third wire groove 521 on the side near the first magnetron 4. The third wire groove 521 and the second wire groove 311 cooperate to form a wiring structure. This arrangement can constrain the connecting wires and strengthen the structure of the mounting bracket 52.

[0051] The second heat dissipation structure includes a third fan 61 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 air outlet side of the second magnetron 6 is provided with the second air guide 62, and the end of the second air guide 62 away from the second magnetron 6 is provided with a second air outlet 63.

[0052] Preferably, the second heat dissipation structure further includes a baffle 53, which is located on the side of the mounting bracket 52 near the second magnetron 6. The baffle 53 includes a vertically arranged third partition, and there is a gap between the third partition and the mounting bracket 52.

[0053] This configuration allows the second magnetron 6 to form a double-layer structure on the side near the air intake space, thereby preventing the heat generated by the second magnetron 6 from directly diffusing into the air intake space, ensuring that the air intake temperature of the third fan 61 is not too high, and providing good heat dissipation for the second frequency converter 7.

[0054] Preferably, one side of the partition 53 is fixedly connected to the third fan 61. This arrangement allows the second heat dissipation structure to be integrated, preventing individual components from becoming loose and generating noise, thus ensuring good operational stability of the cooking equipment.

[0055] Preferably, the second heat dissipation structure further includes a first lower air duct 2 and a fourth fan 71. A second frequency converter 7 is installed inside the first lower air duct 2. The second frequency converter 7 is electrically connected to the second magnetron 6. The fourth fan 71 is installed on the inlet side of the first lower air duct 2, and a first exhaust port 23 is installed on the outlet side of the first lower air duct 2.

[0056] 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.

[0057] Due to comprehensive consideration of various requirements such as the size of the fan's suction space and the space constraints of component placement, the fan corresponding to the third fan 61 of this application is set in the slit between the magnetron and the air duct structure. This makes it difficult for the fan to draw in enough air even when it is operating under overload, thus failing to ensure the flow rate of its heat dissipation airflow.

[0058] Preferably, 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] As an example of this utility model, the first lower housing 21 is provided with a first groove 211 on the side near the base 103 for limiting the connection line of the second heat dissipation structure. This arrangement can constrain the connection line, ensuring a stable and reliable connection and facilitating maintenance.

[0064] 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. To avoid the heat sink 72 affecting the frequency converter body, a first partition 26 is installed in the first air duct cavity 20. The first partition 26 is positioned between the frequency converter body and the heat sink 72, so that their respective heat dissipation does not interfere with each other as much as possible. The first partition 26 is integrally formed with the first lower housing 21 or the first upper housing 22.

[0065] Example 2

[0066] To address the problem of poor heat dissipation performance caused by the unreasonable heat dissipation structure design in existing dual magnetron cooking equipment, the applicant has made further improvements based on Embodiment 1:

[0067] like Figure 1-10 As shown, the cooking equipment includes a furnace cavity assembly, and a rear air duct 1 is provided behind the furnace cavity assembly. The rear air duct 1 has a first flow channel 14 and a second flow channel 15. The air outlet of the inverter 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 equipment.

[0068] As an example of this utility model, the first flow channel 14 is connected to the first exhaust port 23, and the second flow channel 15 is connected to the second air outlet 63. 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 frequency converter 7 and the rear air duct 1, and the second air outlet 63 is connected to or connected to the second air inlet 151 of the second flow channel 15, thereby realizing the combination of the heat dissipation structure of the second magnetron 6 and the rear air duct 1.

[0069] This application, by additionally setting a rear air duct 1, allows the cooling airflow passing through the magnetron and inverter to enter the corresponding channels in the rear air duct 1, and then flow out of the rear air duct 1 in a direction parallel to the wall. This ensures that the cooling airflow exhausted from the cooking equipment does not flow entirely towards the wall, but can flow directly outward along the wall, preventing the cooling airflow from accumulating in the narrow space between the rear of the cooking equipment and the wall. This avoids airflow obstruction and heat accumulation, and helps the cooling airflow to flow out smoothly and diffuse in a timely manner, thereby improving the heat dissipation effect.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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 structure 106. Since these conventional components can all adopt existing technology, they will not be described in detail here.

[0078] 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.
