Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically to an oven with good airflow uniformity. Background Technology

[0002] Existing ovens typically use independent temperature control for the upper and lower parts of the oven, resulting in most of the heat being generated in the upper and lower parts. This leads to uneven heating of the food during baking, which may cause the surface of the food to burn while the inside remains uncooked, severely affecting the taste of the food.

[0003] To address the issue of uneven heating within ovens, existing technologies have made corresponding improvements. For example, Chinese Patent Publication No. CN217090420U discloses a uniform temperature electric oven, including a cavity with a front opening and a temperature equalization component. A heating element is disposed within the cavity, positioned close to the side wall of the cavity. The temperature equalization component includes a fan and an air guide shroud disposed outside the cavity, and also includes a baffle plate positioned at the edge of the front opening of the cavity. This technical solution, through improvements to the temperature equalization component, enables the oven to achieve good temperature uniformity, resulting in more even cooking and color of the baked goods. However, in practical applications, the temperature equalization component has a complex structure, is difficult to install and manufacture, and is difficult to integrate seamlessly with the hot air circulation component, failing to achieve a good uniform airflow effect within the oven. Therefore, further improvements are needed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention proposes an oven with excellent airflow uniformity. Through the structural design of the circulating air cavity and the side airflow uniform plate, the circulating hot air inside the oven can achieve excellent airflow uniformity, thereby improving the baking quality of the oven.

[0005] To achieve the above technical solution, this utility model provides an oven with good airflow uniformity, comprising: an outer box, an inner box installed inside the outer box, a back sealing plate for the air cavity installed on the back of the inner box, a front plate for the air cavity installed in front of the back sealing plate in the inner box, a circulating air distribution hole opened in the center of the front plate for the air cavity, side air distribution plates installed on the left and right sides of the front plate for the air cavity in the inner box, air distribution holes evenly opened on the surface of the side air distribution plates, and a circulating air cavity formed by the gaps between the side air distribution plates, the inner box, the back sealing plate for the air cavity, and the front plate for the air cavity, a circulating fan assembly and an annular heating element are both installed in the circulating air cavity, and the annular heating element is installed on the outside of the circulating fan assembly.

[0006] In the above technical solution, during actual operation, the annular electric heating tube heats the air in the circulating air cavity, and then the heated hot air is evenly blown into the inner box through the circulating air cloth hole opened in the center of the air cavity front plate by the circulating fan assembly. At the same time, under the action of the circulating fan assembly, the hot air in the inner box after heat exchange is evenly blown into the circulating air cavity formed by the side air equalization plates installed on the left and right sides of the inner box, and then evenly enters the circulating air cavity formed by the side air equalization plates, the inner box, the air cavity back sealing plate and the air cavity front plate. After being heated by the annular electric heating tube, the heated hot air is evenly blown into the inner box through the circulating air cloth hole opened in the center of the air cavity front plate by the circulating fan assembly, thereby forming a hot air circulation and saving energy.

[0007] Preferably, the circulating fan assembly includes a motor and a fan blade. The motor is horizontally mounted on the back cover plate of the air cavity, and the fan blade is mounted on the output shaft at the front end of the motor and located inside the circulating air cavity. An annular heating element is mounted on the outside of the fan blade and surrounds it. The fan blade is positioned directly opposite the circulating air distribution hole opened at the center of the front plate of the air cavity. In actual operation, the motor drives the fan blade to rotate, drawing hot air from the periphery of the fan blade and conveying it forward. The hot air is then blown into the inner casing through the circulating air distribution hole opened at the center of the front plate of the air cavity, forming a hot air circulation.

[0008] Preferably, an air intake pipe is installed on the back sealing plate of the air cavity. The outer end of the air intake pipe extends to the outside of the outer casing, and the inner end of the air intake pipe is connected to the circulating air cavity to facilitate the replenishment of fresh air to the circulating air cavity.

[0009] Preferably, multiple shelves are installed on the inner side of the side air distribution plate, arranged vertically and at intervals, to facilitate the placement of food.

[0010] Preferably, a front door is installed on the front side of the outer casing, a handle is installed on the front door, and a viewing glass window is installed in the center of the front door to facilitate the loading and unloading of food and the observation of the food baking process.

[0011] Preferably, a control panel is installed on the left side of the front door of the outer casing to facilitate the setting of oven operating parameters.

[0012] The beneficial effects of the oven with good airflow uniformity provided by this utility model are as follows: The oven with good airflow uniformity has a simple structure and reasonable design. Through the structural design of the circulating air cavity and the side airflow uniform plate, the circulating hot air in the oven can have a good airflow uniformity, thereby improving the baking quality of the oven. In actual operation, the annular heating element heats the air in the circulating air cavity. The heated air is then blown evenly into the inner chamber through the circulating air cloth vents in the center of the front panel of the air cavity by the circulating fan assembly. Simultaneously, under the action of the circulating fan assembly, the heated air in the inner chamber, after heat exchange, is evenly distributed by the side air distribution plates installed on both sides of the inner chamber. It then enters the circulating air cavity formed by the side air distribution plates, the inner chamber, the back sealing plate of the air cavity, and the front panel of the air cavity. After being heated by the annular heating element, the heated air is then evenly blown into the inner chamber through the circulating air cloth vents in the center of the front panel of the air cavity by the circulating fan assembly, thus forming a hot air circulation. This saves energy and ensures a uniform circulation of hot air in the oven, thereby improving the baking quality of the oven. Attached Figure Description

In actual operation, the motor 91 drives the fan blade 92 to rotate, drawing hot air from the periphery of the fan blade 92 and conveying it forward. The hot air is then blown into the inner box 6 through the circulating air distribution hole 13 opened at the center of the air cavity front plate 12, forming a hot air circulation.

At the same time, under the action of the circulating fan assembly 9, the heated air in the inner chamber 6 after heat exchange is evenly blown into the circulating air cavity formed by the side air equalizers 14 installed on the left and right sides of the inner chamber 6. The circulating air cavity is then evenly blown into the inner chamber 6 by the side air equalizers 14, the inner chamber 6, the air cavity back sealing plate 7, and the air cavity front plate 12. After being heated by the annular heating element 8, the heated air is then evenly blown into the inner chamber 6 through the circulating air cloth hole 13 opened in the center of the air cavity front plate 12 by the circulating fan assembly 9, thus forming a hot air circulation, saving energy, and making the hot air in the oven form a uniform circulation flow, thereby improving the baking quality of the oven.
