Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and more specifically, 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 equipment generates and amplifies microwave energy by having two independent magnetron systems work simultaneously or alternately. These microwaves are transmitted to the oven cavity through a waveguide system to heat the food, resulting in a significant increase in the overall heat dissipation load. This poses a challenge to the stable operation of components such as lamps and infrared sensors located on the side of the cavity.

[0004] To this end, the applicant conducted research and submitted Chinese Patent Publication No. CN119063036A, which discloses a microwave oven including an inner cavity and a first partition. The first partition is equipped with a lighting component and a temperature sensing component. An air guide hood is located on the side of the first partition away from the inner cavity. The air guide hood cooperates with the first partition to form the air duct structure. A fan is located at one end of the air guide hood to drive airflow and simultaneously dissipate heat from the lighting component and the temperature sensing component. This solution enables relatively stable operation of components such as the lighting component and the temperature sensing component. However, subsequent research by the applicant revealed that when the cooking cavity performs special functions such as grilling, the lighting component and the temperature sensing component located on the side are exposed to high ambient temperatures, resulting in poor operational stability and reliability.

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

A wind guide hood, a lighting component, and a temperature sensing component are disposed on the side of the cavity assembly. A fifth fan is disposed at one end of the wind guide hood, which is used to guide airflow to the lighting component and the temperature sensing component for heat dissipation.

[0011] Preferably, the air guide cover further includes a fastening element located between the two air guide elements.

An air guide hood is provided on the side of the mounting plate away from the heat insulation rack, and an air supply duct is formed between the air guide hood and the mounting plate. The mounting plate is made of non-metallic material.

[0013] Preferably, a magnetron heat dissipation structure and a frequency converter heat dissipation structure are provided below the cavity assembly, and a rear air duct is provided behind the cavity assembly. The rear air duct has a first flow channel and a second flow channel. The air outlet of the frequency converter heat dissipation structure is connected to the first flow channel, and the air outlet of the magnetron heat dissipation structure is connected to the second flow channel. The air outlet direction of the first flow channel and the air outlet direction of the second flow channel are both parallel to the wall directly opposite the rear side of the cooking equipment.

Detailed Implementation

[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0033] Example 1

[0034] like Figure 1-8As shown, a 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.

[0035] 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.

[0036] 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.

[0037] 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. The first air outlet 1042 is directly opposite the air outlet of the first flow channel 14, and the second air outlet 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.

[0038] 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.

[0039] Preferably, 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 at corresponding positions on the side wall 1044.

[0040] The rear air duct 1 has a protrusion 11 for avoiding the waveguide box 105 of the cooking device, thus preventing spatial interference between components. The protrusion 11 is not independent of the flow channel structure and may partially overlap with the first flow channel 14 and / or the second flow channel 15 in terms of structure. The shape of the flow channel wall of the corresponding flow channel can be appropriately adjusted to avoid the space of the waveguide box 105. Correspondingly, the cooking device includes a drive motor 1051. The structure of the drive motor 1051 in conjunction with the waveguide box 105, stirrer, etc., can refer to the prior art.

[0041] The drive 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 drive motor 1051. Therefore, in the process of discharging the cooling airflow from the magnetron or the inverter, this application also allows the cooling airflow to flow through the drive motor 1051 for cooling, which helps improve 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 disposed 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.

[0042] In this application, the two magnetrons are referred to as the first magnetron 4 and the second magnetron 6, 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.

[0043] 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.

[0044] As an example of this utility model, the cooking device includes a base 103, 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; a first fan 41 is provided on the air inlet side of the first magnetron 4, a first air guide 42 is provided on the air outlet side of the first magnetron 4, and 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 vent 1031;

[0045] The first frequency converter 5 is installed in the second lower air duct 3. A second fan 51 is installed on the air inlet side of the second lower air duct 3, and a second exhaust port 33 is installed 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. Accordingly, the second lower air duct 3 is assembled from a second lower housing 31 and a second upper housing 32.

[0046] Regarding the heat dissipation structure related to the second magnetron 6 and the second frequency converter 7, the details are as follows:

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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, which will not be elaborated further. 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 directly formed.

[0054] 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.

[0055] Example 2

[0056] like Figure 9-12 As shown, a cooking device includes a cavity assembly, which includes a cooking cavity and a heat insulation rack 9 arranged sequentially from the inside to the outside. A heat insulation component is provided between the cooking cavity and the heat insulation rack 9. A first magnetron 4 and a second magnetron 6 are provided at the bottom of the cavity assembly for emitting microwaves into the cooking cavity. The cooking device also includes a lighting component 121 and a temperature sensing component 122 located on the side of the cavity assembly. An air guide shroud 8 is provided on the side of the cavity assembly, and a fifth fan 125 is provided at one end of the air guide shroud 8 for driving airflow to simultaneously dissipate heat from the lighting component 121 and the temperature sensing component 122.

[0057] This setup utilizes a single fan 4 to simultaneously dissipate heat from the lighting assembly 121, the temperature sensing assembly 122, and the microswitch 123 of the door 101, meeting the heat dissipation requirements of the side of the dual magnetron microwave oven. By setting up the heat insulation rack 9 and heat insulation components, heat transfer from the oven cavity to the outside can be effectively prevented, thus preventing heat transfer from the cooking cavity to the side and affecting the operational stability of the lighting assembly 121, the temperature sensing assembly 122, and the microswitch 123. At the same time, it can effectively concentrate heat in the cooking cavity, ensuring a good heating rate inside the oven cavity, which helps to improve cooking efficiency, ensure cooking results, and reduce energy loss caused by heat transfer from the oven cavity to the outside.

[0058] As an example of this utility model, the lighting assembly 121 includes a first lamp body 1211 and a second lamp body 1212, with the first lamp body 1211 located above the second lamp body 1212; the temperature sensing assembly 122 includes a first sensor and a second sensor, with the first sensor located above the second sensor and downstream of the first lamp body 1211.

[0059] As an example of this utility model, the air guide cover 8 includes a first base plate 81 that is fitted to the heat insulation frame 9. A first baffle 82 is provided around the first base plate 81. The first base plate 81 and the first baffle 82 form an installation position for fixing and assembling the fifth fan 125. An air outlet 84 is provided on one side of the first baffle 82 for supplying air to the lighting component 121 and the temperature sensing component 122.

[0060] Preferably, the air guide cover 8 further includes a second base plate 83, which is located on the upper edge of the first baffle 82 and extends away from the first baffle 82. The second base plate 83 is provided with a second baffle 85 and a partition plate 851 on the side near the heat insulation frame 9. The second baffle 85 is located on the outer edge of the second base plate 83 and cooperates with the partition plate 851 to form a first air duct 831, a second air duct 832, and a third air duct 833. The first air duct 831 and the second air duct 832 are used for heat dissipation of the second lamp body 1212 and the second sensor, respectively, and the third air duct 833 is used for heat dissipation of the first lamp body 1211 and the first sensor.

[0061] Preferably, the air guide shroud 8 has an air intake element 87 on the side away from the first base plate 81, and a micro switch 123 is provided on the side of the cavity assembly. The air intake element 87 is positioned directly opposite the micro switch 123 to dissipate heat from the micro switch 123. This arrangement, utilizing the fifth fan 125, can simultaneously dissipate heat from the lighting assembly 121, the temperature sensing assembly 122, and the micro switch 123, ensuring stable and reliable overall operation of the cooking equipment.

[0062] Preferably, there are two air-guiding elements 87 arranged vertically at intervals. This arrangement can dissipate heat from multiple microswitches 123, while guiding airflow on the side of the cooking cavity to prevent hot air from entering the electrical installation area located at the bottom of the cavity, resulting in a long service life and reliable operation of the cooking device.

[0063] Preferably, the cooking device further includes a mounting plate 10, which is fixed to the heat insulation rack 9. An air guide shroud 8 is provided on the side of the mounting plate 10 away from the heat insulation rack 9, forming an airflow duct between the air guide shroud 8 and the mounting plate 10. The mounting plate 10 is made of a non-metallic material. This arrangement enables the mounting plate 10 to provide heat insulation, preventing heat from the heat insulation rack 9 from being conducted to the air guide shroud 8, thus keeping the temperature on the side of the cooking cavity lower and improving heat dissipation.

[0064] Preferably, the air guide shroud 8 further includes a fastener 86 located between the two air guide components 87 for securing the connecting wires. The air guide shroud 8 is assembled to the mounting plate 10 and / or the heat insulation frame 9 by screwing and / or plugging. This arrangement allows for pre-positioning via plugging, balancing ease of assembly with secure fastening.

[0065] Preferably, the cooking device further includes a heating assembly, which includes a first heating element and a second heating element. The first heating element is disposed between the cooking cavity and the heat insulation element, and the second heating element is located above the bottom of the cooking cavity.

[0066] Therefore, in addition to the conventional bottom second heating element, this embodiment additionally sets a first heating element between the cooking cavity and the heat insulation element. By directly heating the plate structure of the cooking cavity, more heat is provided to the cooking cavity, enabling the cooking equipment to reach a higher cooking temperature and realize the functions of grilling or microwave + grilling. In addition, by heating the cooking cavity, heat can be conducted to the oven cavity, which can improve the uniformity of temperature distribution in the oven cavity and avoid local burning.

[0067] 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, and an electrical control component 106. Preferably, ventilation holes are provided at positions corresponding to the fifth fan 125 on the U-shaped outer shell 102. Since these conventional components all adopt existing technology, they will not be described in detail here.

[0068] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
