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 improvement of living standards, microwave ovens have become an indispensable cooking appliance in modern households; however, due to their relatively limited functions, they cannot meet consumers' diverse needs for cooking methods. In this context, microwave ovens with grilling functions have gradually become more popular. To achieve precise control, infrared sensors are typically installed on the side wall of the heating cavity to detect temperature changes on the surface of the food to be cooked. Microwave power is then adjusted based on these temperature changes to control the heating process. Since the internal temperature of microwave ovens with heating elements rises significantly, the high temperature can affect the reliability and stability of the infrared sensors.

[0003] To address this, Chinese Patent Application No. 201420246016.6 discloses the internal structure of a microwave oven control chamber, including an inverter assembly, an infrared sensor, and a fan. The inverter assembly includes an inverter and an inverter housing housing the inverter, which is mounted on the rear side of the control chamber. The infrared sensor is located in the upper center of the control chamber, in front of the inverter housing. The fan is mounted on the rear side of the control chamber, below the inverter housing. The inverter housing has an air inlet at the bottom facing the fan, a first air outlet at the top facing the rear of the top surface of the control chamber, a second air outlet on the side facing the inverter, and a third air outlet at the front facing the infrared sensor. This design improves the cooling effect on the infrared sensor, but the structure is complex, requiring a separate air duct for heat dissipation, resulting in a complex structure and difficult assembly.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] The problem solved by this invention is that the structure of existing cooking equipment, especially cooking equipment with grilling function, is unreasonable, resulting in poor operational stability and reliability of infrared sensors.

[0006] To address the aforementioned problems, this utility model provides a cooking device, including a heating chamber. An air supply bracket is provided on the side of the heating chamber to provide a mounting position for an air supply component. The air supply component is used to drive airflow to dissipate heat from components located on the side of the heating chamber. An infrared sensor is provided on the side of the air supply bracket near the heating chamber to detect the temperature of the food to be cooked inside the heating chamber. The air supply component drives a portion of the airflow through the infrared sensor to dissipate heat from it.

[0007] This setup utilizes existing air supply components to deliver some of the cold outside air to the infrared sensor for heat dissipation, ensuring stable and reliable operation when the hot air module is working; it requires minimal modification to the existing structure and is convenient for production and processing.

[0008] Preferably, an air inlet is provided on the upper side of one side of the air supply bracket, the air inlet is connected to the mounting position of the air supply component, and a mounting bracket is provided at the air inlet for limiting the assembly of the infrared sensor, the infrared sensor being positioned facing the lower front of the heating cavity.

[0009] This setup ensures that the infrared sensor is positioned close to the top edge of the heating chamber. The downward-sloping infrared sensor can completely cover and receive infrared rays from the food to be heated, resulting in good temperature measurement.

[0010] Preferably, the infrared sensor includes a probe, the mounting bracket has mounting holes, and the probe is fitted into the mounting holes for positioning; a glass turntable is disposed within the heating cavity, and the probe is positioned directly opposite the center point of the glass turntable. This arrangement allows for simultaneous assembly of the infrared sensor and constraint of the probe's orientation, resulting in a simple structure that is easy to manufacture. The mounting bracket and the air supply bracket can be separate or integrally formed, and their specific structure and assembly relationship are existing technologies.

[0011] Preferably, the air supply bracket includes a horizontally placed top panel, with the air inlet located at the end of the top panel; a vertically placed support frame is provided below the top panel, and an arc-shaped air guide ring is provided above one side of the support frame to form a semi-enclosed structure. This arrangement makes the air supply bracket semi-enclosed, which can drive most of the air-cooled air to flow towards the magnetron facing the fan, and can also significantly improve the convective heat dissipation effect of components such as capacitors located below the air supply assembly, thereby improving the heat dissipation effect of the cooking equipment.

[0012] Preferably, the air supply bracket further includes a side plate located between the air guide ring and the top panel and close to the air inlet, for converging some air towards the air inlet. This arrangement can further increase the airflow at the air inlet and also improve the mechanical strength of the air supply bracket.

[0013] Preferably, the air supply assembly includes a fan and a motor, and the drive shaft of the motor passes through the support frame and is connected to the fan drive.

[0014] Preferably, the cooking device further includes a horizontally placed filter plate, and the air supply bracket includes a horizontally placed top panel. The filter plate is fixedly mounted above the top panel with a gap between it and the top panel. This arrangement brings the filter plate close to the top of the microwave oven for easy connection to the power cord. Simultaneously, the air supply assembly can drive airflow around the filter plate during operation to dissipate heat, ensuring stable and reliable operation. Furthermore, eliminating the need for a support plate for the filter plate makes the overall structure more compact.

[0015] Preferably, the heating chamber includes a rear side plate, the air supply bracket is disposed close to the rear side plate, the rear side plate is provided with ventilation holes, and the air supply assembly is disposed directly opposite the ventilation holes. This arrangement has a compact structure and high space utilization.

[0016] Preferably, the cooking device further includes a magnetron, a capacitor, and a frequency converter. The magnetron is located on the side of the heating cavity and directly opposite the air outlet of the air supply component. The frequency converter is located below the magnetron, and the capacitor is located directly below the air supply bracket and adjacent to the frequency converter. This arrangement, through reasonable optimization of the internal structure of the cooking device, enables a single air supply component to dissipate heat from the components on the side of the heating cavity, resulting in stable and reliable operation.

[0017] Preferably, the cooking device further includes a hot air structure, the hot air structure including a heating element located inside the heating cavity, the heating cavity including a top plate, the top plate portion protruding upward to form a first clearance portion for accommodating the heating element.

[0018] This design improves the structure of the top plate so that the heating element is installed directly inside the oven cavity. The heating element is close to the food to be cooked and there is no obstruction in between, so the heat radiation generated can directly act on the surface of the food, resulting in good cooking effect. At the same time, the first clearance part located above the heating element can prevent excessive heat from being conducted upward and causing the top to overheat, thus ensuring high safety.

[0019] Compared with the prior art, the cooking equipment described in this utility model embodiment has the following beneficial effects: 1) By setting the infrared sensor on the air supply bracket, the air supply component can drive a portion of the air to flow through the infrared sensor for heat dissipation, thereby improving operational stability and reliability; 2) By setting the filter plate on the top of the air supply bracket, the filter plate mounting bracket can be eliminated and assembly efficiency can be improved. At the same time, the air supply component can be used to dissipate heat from the filter plate, ensuring its stable and reliable operation; 3) Through the semi-enclosed air supply bracket, most of the air-cooled air can be driven to flow towards the magnetron facing the fan, which can also significantly improve the convective heat dissipation effect of components such as capacitors located below the air supply component, thereby improving the heat dissipation effect of the cooking equipment; 4) Only one air inlet needs to be opened on the air supply bracket, which requires little modification to the existing structure and is low in cost.

[0031] Microwave ovens, as common household appliances, are popular due to their convenience, speed, and ease of operation. With rising living standards, consumers' demands for cooking equipment are becoming increasingly diverse, and microwave ovens with grilling functions are gaining popularity. However, when the grilling mode is activated, the temperature of the heating cavity rises significantly, which can affect the stability and reliability of the infrared sensor. Therefore, the applicant proposes the following technical solution:

[0032] like Figure 1-6 As shown, a cooking device includes a heating chamber 6. An air supply bracket 1 is provided on the side of the heating chamber 6 to provide a mounting position for an air supply assembly 2. The air supply assembly 2 is used to drive airflow to dissipate heat from components located on the side of the heating chamber 6. An infrared sensor 4 is provided on the side of the air supply bracket 1 near the heating chamber 6 to detect the temperature of the food to be cooked in the heating chamber 6. The air supply assembly 2 drives a portion of the airflow through the infrared sensor 4 to dissipate heat from it.

[0033] This setup utilizes the existing air supply component 2 of the cooking equipment to deliver some of the outside cold air to the infrared sensor 4, ensuring stable and reliable operation; it requires minimal modification to the existing structure and facilitates production and processing.

[0034] Preferably, the upper end of the air supply bracket 1 is provided with an air inlet 131, the air inlet 131 is connected to the mounting position of the air supply assembly 2, and a mounting bracket 3 is provided at the air inlet 131 for fixing and assembling the infrared sensor 4. The infrared sensor 4 is positioned facing the lower front of the heating cavity 6.

[0035] This setup ensures that the infrared sensor 4 is positioned close to the top edge of the heating chamber 6. The downwardly tilted infrared sensor 4 can completely cover and receive infrared rays from the food to be heated, resulting in good temperature measurement. The structure is simple and easy to manufacture.

[0036] As an example of this utility model, the air supply bracket 1 includes a support frame 11, and the air supply assembly 2 includes a fan 21 and a motor 22. The drive shaft of the motor 22 passes through the support frame 11 and is driven to connect with the fan 21.

[0037] Preferably, the air supply bracket 1 further includes a top panel 12, which is horizontally placed and perpendicular to the support frame 11. An air guide ring 14 is disposed below the top panel 12, located between the top panel 12 and the fan 21. The projection of the air guide ring 14 onto the support frame 11 is arc-shaped with an arc radius of 1 / 2π to π. This configuration gives the air supply bracket 1 a semi-enclosed structure, enabling it to drive most of the cooled airflow towards the magnetron 7 facing the fan 21. It also significantly improves the convective heat dissipation effect of components such as the capacitor 8 located below the air supply assembly 2, thereby enhancing the heat dissipation effect of the cooking equipment.

[0038] As an example of this invention, the cooking device further includes a horizontally placed filter plate 5, which is located above the top panel 12 and has a gap with it. This arrangement brings the filter plate 5 close to the top of the microwave oven for easy connection to the power cord, while the air supply assembly 2 can drive the airflow around the filter plate 5 during operation to dissipate heat from it, ensuring stable and reliable operation; at the same time, eliminating the need for a support plate for the filter plate 5 makes the overall structure more compact.

[0039] As an example of this utility model, the air supply bracket 1 further includes a side plate 15, which is located between the air guide ring 14 and the top panel 12 and close to the air inlet 131, for converging some air towards the air inlet 131. This arrangement can further increase the air volume at the air inlet 131, and also improve the mechanical strength of the air supply bracket 1.

[0040] Preferably, the air supply bracket 1 includes a vertical plate 13 located at one end of the top panel 12. The vertical plate 13 is perpendicular to both the support frame 11 and the top panel 12, and an air inlet 131 is provided on the vertical plate 13. This arrangement can further improve the mechanical strength of the air supply bracket 1, and also facilitate the installation and fixing of the air supply bracket 1.

[0041] As an example of this utility model, the infrared sensor 4 includes a probe 41, and the mounting bracket 3 is provided with a mounting hole 31, into which the probe 41 is limited and fitted. A glass turntable is provided inside the heating cavity 6, and the infrared sensor 4 is positioned facing the center point of the glass turntable. The side wall of the heating cavity 6 is provided with clearance holes, allowing the infrared rays generated by the food to be cooked to pass smoothly through the side wall of the heating cavity 6 and be received by the infrared sensor 4. Its specific structure is prior art and will not be described in detail here.

[0042] Preferably, the heating chamber 6 includes a rear side plate 61, the air supply bracket 1 is arranged parallel to the rear side plate 61, the rear side plate 61 is provided with ventilation holes 611, and the air supply assembly 2 is arranged directly opposite the ventilation holes 611. This arrangement makes the cooking equipment compact and space-efficient.

[0043] The cooking device also includes a magnetron 7, a capacitor 8, and a frequency converter 9. The magnetron 7 is located on the side of the heating chamber 6 and directly opposite the air outlet of the air supply assembly 2. The frequency converter 9 is located below the magnetron 7, and the capacitor 8 is located directly below the air supply bracket 1 and adjacent to the frequency converter 9. This arrangement, through reasonable optimization of the internal structure of the cooking device, enables a single air supply assembly 2 to dissipate heat from the components on the side of the heating chamber 6, resulting in stable and reliable operation.

[0044] Preferably, the cooking device further includes a hot air structure 10, which includes a heating element located inside the heating chamber 6. The heating chamber 6 includes a top plate, and a portion of the top plate protrudes upward to form a first clearance portion for accommodating the heating element.

[0045] This design improves the top plate structure, allowing the heating element to be directly installed within the heating chamber 6. The heating element is close to the food being cooked with no obstructions, ensuring direct heat radiation to the food surface and resulting in excellent cooking. Simultaneously, the first clearance section above the heating element prevents excessive heat from rising and overheating the top, ensuring high safety. The hot air structure also includes a fan to drive air circulation for heating. The cooking device also includes a door assembly, control panel, and other structures; their specific structures and assembly relationships are existing technology and will not be described in detail here.

[0046] 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.
