Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to an oven and an integrated stove. Background Technology

[0002] In modern cooking equipment, ovens have become an essential appliance in both home and commercial kitchens. During the cooking process, the temperature distribution inside the oven cavity is often uneven, which significantly affects the cooking results, especially when a baking tray is used as the cooking medium.

[0003] As is well known, heat in an oven is primarily transferred through forced convection generated by the rear fan shroud and fan blades. However, this basic structure suffers from uneven airflow within the cavity, resulting in significant temperature differences across different areas of the baking tray / rack. This is mainly manifested in the fact that when the air blown into the oven cavity by the circulating fan transitions from the edge of the fan shroud into the cavity, the existing structural design leads to substantial localized airflow loss, making it difficult to create an ideal and stable circulating flow field.

[0004] Therefore, in order to improve the user experience and oven temperature uniformity, a new oven structural design is needed to make the temperature distribution inside the cavity more uniform and improve the cooking quality. Utility Model Content

The fan cover is disposed on the side or back of the inner liner, and the circulating fan is disposed inside the fan cover. The fan cover is provided with a first ventilation hole and a second ventilation hole. The outer edge of the fan cover is provided with an edge portion having a draft angle. The first ventilation hole is provided on the edge portion. The second ventilation hole is provided in a preset area of ​​the fan cover. The center of the preset area coincides with the center of the fan cover. The distance from the edge portion to the preset area is greater than a preset distance. The number of the first ventilation holes is multiple, and the multiple first ventilation holes are evenly distributed on the edge portion; the circulating fan blows air into the oven through the first ventilation holes and the second ventilation holes.

[0006] Furthermore, the draft angle ranges from 5° to 15°.

[0007] Furthermore, the diameter of the first ventilation hole is smaller than the width of the edge portion; the width of the edge portion ranges from 1.4 cm to 1.6 cm.

[0008] Furthermore, the first ventilation holes are arranged in a single row in the first preset direction; the first preset direction is a direction perpendicular to the bottom surface of the inner liner.

[0009] Furthermore, the first ventilation holes are arranged in a single row in the second preset direction; the second preset direction is a direction parallel to the bottom surface of the inner liner.

[0010] Furthermore, the width of the fan cover ranges from 18 cm to 22 cm.

[0011] Furthermore, the fan cover is also provided with a support component, which is a support prism or a support bracket.

[0012] Furthermore, the number of supporting prisms is at least two, and the supporting prisms are symmetrically distributed on both sides of the fan cover; the shape of the supporting prisms is a triangular prism.

[0020] like Figure 1-5 As shown, the present invention provides an oven, which includes an inner liner, a fan cover 1 and a circulating fan. The fan cover 1 is disposed on the side or back of the inner liner, and the circulating fan is disposed inside the fan cover 1. The fan cover 1 is provided with a first ventilation hole 11 and a second ventilation hole 12. The outer edge of the fan cover 1 is provided with an edge portion 13 having a draft angle. The first ventilation hole 11 is provided on the edge portion 13. The second ventilation hole 12 is provided in a preset area of ​​the fan cover 1. The center of the preset area coincides with the center of the fan cover 1. The distance from the edge portion 13 to the preset area is greater than a preset distance. There are multiple first ventilation holes 11, which are evenly distributed on the edge portion 13; the circulating fan blows air into the oven through the first ventilation holes 11 and the second ventilation holes 12.

[0021] For example, the fan cover 1 in the oven can be set on the side or back of the oven cavity, and the circulating fan is set inside the fan cover 1. The fan cover 1 is provided with ventilation holes. When the circulating fan is working, it blows air into the oven through the ventilation holes on the fan cover 1 to provide heat to the oven.

[0022] For example, the ventilation holes on the fan cover 1 may include a first ventilation hole 11 and a second ventilation hole 12. The outer edge of the fan cover 1 is an edge portion 13 with a draft angle. The first ventilation hole 11 is disposed on the edge portion 13 to achieve side airflow. The second ventilation hole 12 may be disposed in a preset area on the fan cover 1, such as the central area of ​​the fan cover 1, to achieve front airflow. The distance from the edge portion 13 of the fan cover 1 to the preset area is greater than a preset distance, ensuring that the first ventilation hole 11 and the second ventilation hole 12 are distributed in different areas on the fan cover 1, so that the airflow from the circulating fan can enter the oven from different positions, forming a stable circulating flow field and making the temperature distribution inside the oven more uniform. By setting the edge of the fan cover 1 as an edge portion 13 with a draft angle and improving the layout of the ventilation holes on the fan cover 1, this utility model can achieve airflow from different directions, such as the front and sides, making the temperature distribution inside the oven more uniform and improving the cooking quality.

[0023] For example, the number of the aforementioned first ventilation holes 11 is multiple, such as... Figure 1 As shown, the first ventilation holes 11 can be evenly distributed on the edge portion 13 around the fan cover 1, ensuring that the first ventilation holes 11 are distributed on the edge portion 13 in all directions, improving the air blowing efficiency of the circulating fan to all directions inside the oven, and ensuring the uniformity of the temperature distribution inside the oven.

[0024] Furthermore, the aforementioned draft angle ranges from 5° to 15°.

[0025] For example, in order to achieve side airflow, the edge portion 13 of the aforementioned fan cover 1 has a certain draft angle, which can be within the range of 5°-15°. When the circulating fan blows air to the side of the fan cover 1, the air can be discharged into the oven through the first ventilation hole 11 on the edge portion 13, optimizing the airflow and effectively solving the problem of large local airflow loss caused by the existing structural design of the fan cover 1, making it difficult to form an ideal stable circulating flow field.

[0026] This invention optimizes the airflow inside the oven by providing an edge portion 13 with a certain draft angle along the edge of the fan cover 1 and providing a first ventilation hole 11 on the edge portion 13, thereby achieving uniform temperature distribution inside the oven.

[0027] Furthermore, the diameter of the first ventilation hole 11 is smaller than the width of the edge portion 13; the width of the edge portion 13 ranges from 1.4 cm to 1.6 cm.

[0028] For example, the diameter of the first ventilation hole 11 needs to be smaller than the width of the edge portion 13, wherein the width of the edge portion 13 can be in the range of 1.4 cm to 1.6 cm. The first ventilation hole 11 and the edge portion 13 are adapted to each other, which not only ensures that the circulating fan blows air evenly into the oven, but also makes the structure of the fan cover 1 more reliable, avoiding damage to the edge portion 13 of the fan cover 1 and affecting the user experience of the oven. In an exemplary embodiment, the dimensions of the multiple first ventilation holes 11 are all the same, realizing uniform airflow from the side.

[0029] This invention controls the diameter of the first ventilation hole 11, enabling it to fit perfectly with the fan cover 1, thereby improving the overall product quality of the fan cover 1. Furthermore, the first ventilation holes 11 are arranged in a single row in the first preset direction; the first preset direction is a direction perpendicular to the bottom surface of the inner liner.

[0030] Furthermore, the first ventilation holes 11 are arranged in a single row in the second preset direction; the second preset direction is a direction parallel to the bottom surface of the inner liner.

[0031] For example, the first ventilation holes 11 are arranged in a single row in the vertical direction, so that there are first ventilation holes 11 arranged in a row on both the left and right sides of the fan cover 1, so as to achieve uniform air outlet on the left and right sides.

[0032] For example, the first ventilation holes 11 are arranged in a single row in the horizontal direction, so that there are rows of first ventilation holes 11 on both the upper and lower sides of the fan cover 1, so as to achieve uniform airflow from both the upper and lower sides. The first ventilation holes 11 are provided on the edge portions 13 in the four directions of the fan cover 1, which can effectively balance the airflow in various areas inside the oven. Whether the food is placed in the upper area, lower area or side area inside the oven for cooking, efficient cooking can be achieved.

[0033] This invention arranges the first ventilation holes 11 in a single row or a single column on the edge portion 13, which enables uniform airflow in four directions: up, down, left, and right, improving the uniformity of side airflow and ensuring that the circulating fan can blow air to all areas inside the oven.

[0034] Furthermore, the width of the aforementioned fan cover 1 ranges from 18 cm to 22 cm.

[0035] For example, the width of the fan cover 1 can be set in the range of 18 cm-22 cm to better adapt to the structure of the oven. A reasonable size of the fan cover 1 can optimize the flow of hot air inside the oven and ensure that the air from the circulating fan can be effectively transmitted to the entire internal space of the oven through the ventilation holes on the fan cover 1. This avoids hot air circulating only in a local area of ​​the oven, which would result in uneven temperature distribution in different areas of the oven and uneven heating of the food inside the oven, thus affecting the cooking effect of the food.

[0036] This invention features a well-designed fan cover 1, which is better suited to the oven and ensures that the airflow from the circulating fan can be effectively delivered to all areas inside the oven.

[0037] Furthermore, the fan cover 1 is also provided with a support component, which is a support prism 14 or a support fixing seat 15.

[0038] For example, in order to make the structure of the fan cover 1 more adaptable to the oven and to place components such as baking trays, racks, and steaming trays to meet diverse cooking needs, a support component can be provided on the fan cover 1. The support component can be a support prism 14 or a support fixing seat 15.

[0039] This utility model, by setting a support component on the fan cover 1, can adapt to various cooking needs and facilitate the placement of baking trays, grills and other components.

[0040] Furthermore, the number of the aforementioned supporting prisms 14 is at least two, and the aforementioned supporting prisms 14 are symmetrically distributed on both sides of the aforementioned fan cover 1; the shape of the aforementioned supporting prisms 14 is a triangular prism.

[0041] For example, if the above-mentioned support component is a support prism 14, the number of support prisms 14 is at least two, and they are symmetrically distributed on both sides of the fan cover 1 to ensure more stable support for components such as baking trays and grills. Figure 3 This is a schematic diagram of a fan cover 1 with supporting prisms 14 provided in an embodiment of this application. The fan cover 1 in the figure has 6 supporting prisms 14, which are symmetrical in structure, making the structure of the fan cover 1 more stable and reliable, and providing stable support. Figure 4 This is a schematic diagram of another fan cover 1 provided with supporting prisms 14, according to an embodiment of this application. Figure 4 The edge portion 13 of the fan cover 1 and the first ventilation hole 11 are not shown in the diagram. With multiple supporting prisms 14 provided on the fan cover 1, the user can choose to place the baking tray or grill rack in different positions according to the actual cooking needs, which improves the convenience of using the oven. It can also place multiple baking trays or grill racks at the same time to meet the needs of cooking a large amount of food at the same time and improve cooking efficiency.

[0042] For example, the supporting prism 14 can be a triangular prism. The triangular prism has a simple and reliable structure, providing more stable support for components such as baking trays and racks with a simple structure. In addition, other shaped prisms can also be set on the fan cover 1 to facilitate the placement of components such as baking trays and racks, meet different cooking needs of the oven, and improve the convenience of using the oven.

[0043] This utility model provides stable support by setting mutually symmetrical support prisms 14 on the fan cover 1, which facilitates the placement of components such as baking trays and grill racks and prevents them from falling off during cooking, thus affecting the user experience.

[0044] Furthermore, the distance from the support bracket 15 to the top of the fan cover 1 is the first distance, and the distance from the support bracket 15 to the bottom of the fan cover 1 is the second distance, wherein the first distance is equal to the second distance.

[0045] For example, if the aforementioned support component is a support fixing seat 15, one support fixing seat 15 can be provided on each side of the fan cover 1. The support fixing seat 15 can be located at the middle position on both sides of the fan cover 1, that is, the distance from the support fixing seat 15 to the top of the fan cover 1 is equal to the distance from the support fixing seat 15 to the bottom of the fan cover 1. When the support fixing seat 15 is provided, a shelf needs to be provided simultaneously to place components such as baking trays and grill racks. Figure 5 This is a schematic diagram of a fan cover 1 provided with a support and fixing base 15, according to an embodiment of this application. Figure 5 The middle shelf is not shown.

[0046] This utility model provides another structure for placing baking trays, grill racks and other components, which can also meet the different cooking needs of users and improve the convenience of using the oven.

[0047] This invention improves the layout of the ventilation holes on the fan cover 1, ensuring uniform airflow when the circulating fan blows air to the side and front, preventing hot air from concentrating in a localized area inside the oven and improving the uniformity of temperature distribution inside the oven. By setting the edge of the fan cover 1 as an edge portion 13 with a draft angle and setting multiple first ventilation holes 11 on the edge portion 13, the side airflow of the circulating fan can be achieved, improving the airflow distribution inside the oven. A second ventilation hole 12 is set in the central area of ​​the fan cover 1, enabling the circulating fan to blow air evenly in all directions inside the oven, making the heat distribution inside the oven more uniform. By setting a support component on the fan cover 1, it is convenient to place baking trays, racks, and other components to meet different cooking needs of the oven and improve the convenience of using the oven.

[0048] In one exemplary embodiment, the present invention also provides an integrated stove, which is equipped with an oven as described above. When cooking food, the circulating fan in the oven can achieve side blowing and front blowing through the first ventilation hole 11 and the second ventilation hole 12 on the fan cover 1, so as to transmit hot air to various areas in the oven, ensure the uniformity of temperature distribution inside the oven, and improve the cooking quality.

[0049] The beneficial effects of this utility model are: The oven of this utility model includes an inner cavity, a fan cover, and a circulating fan. The fan cover is located on the side or back of the inner cavity, and the circulating fan is located inside the fan cover. The fan cover has a first ventilation hole and a second ventilation hole. The outer edge of the fan cover has an edge portion with a draft angle, and the first ventilation hole is located on the edge portion. The second ventilation hole is located in a preset area of ​​the fan cover, and the center of the preset area coincides with the center of the fan cover. The distance from the edge portion to the preset area is greater than a preset distance. There are multiple first ventilation holes, which are evenly distributed on the edge portion. The circulating fan blows air into the oven through the first ventilation hole and the second ventilation hole. This invention improves the layout of the ventilation holes on the fan cover, ensuring uniform airflow when the circulating fan blows air to the side and front, preventing hot air from concentrating in a localized area inside the oven and improving the uniformity of temperature distribution. By setting the edge of the fan cover to have a draft angle and setting multiple first ventilation holes on the edge, the circulating fan can be vented from the side, improving the airflow distribution inside the oven. A second ventilation hole is set in the central area of ​​the fan cover, enabling the circulating fan to vent air to the front, allowing the circulating fan to vent air evenly in all directions inside the oven, making the heat distribution inside the oven more uniform. By setting a support component on the fan cover, it is easy to place baking trays, racks, and other components, meeting different cooking needs of the oven and improving the convenience of use.

[0050] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
