Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen utensils, in particular to a cooking device. BACKGROUND

[0002] In the oven, the hot air blower and the deflector plate optimize the circulation and distribution of hot air in the inner container through mutual coordination, so as to ensure the uniform heating and cooking effect of food. Among them, the hot air blower drives the flow of hot air to form a hot air flow, avoiding overheating or insufficient heating in some areas of the oven. The deflector plate is usually located directly in front of the outlet of the hot air blower, and a plurality of deflector holes are arranged on the deflector plate. The deflector plate guides and distributes the flow direction of the hot air flow through these deflector holes, so that the hot air flow can uniformly cover each area in the inner container, preventing the occurrence of air flow dead angle (i.e. the area where the hot air flow cannot reach), and ensuring the uniform heating of food.

[0003] In the existing oven, the size of the inner container in the height direction is large, and the height difference between the upper deflector hole of the deflector plate (i.e. the deflector hole located on the upper side of the deflector plate) and the top wall in the inner container is large. The hot air flow from the upper deflector hole of the deflector plate has sufficient space to flow obliquely upward, and these hot air flows can fully flow to the area far away from the hot air blower, and there is no air flow dead angle in the inner container. However, some users want to reduce the height size of the oven to embed it in a smaller space for use, which requires reducing the height size of the inner container, thereby reducing the height difference between the upper deflector hole of the deflector plate and the top wall in the inner container, and causing the hot air flow from the upper deflector hole of the deflector plate to hit the inner top wall of the inner container after flowing obliquely upward for a very small distance. After the upward flowing hot air flow hits the inner top wall of the inner container, its kinetic energy decreases. Therefore, the hot air flow from the upper deflector hole of the deflector plate is difficult to flow to a far place because it only flows obliquely upward for a very small distance before hitting the inner top wall of the inner container. Especially when the height size of the inner container is small and the hot air blower is arranged on one side of the inner container in the length direction, the hot air flow needs to flow a large horizontal distance to reach the area far away from the hot air blower. The hot air flow from the upper deflector hole of the deflector plate cannot flow to the area far away from the hot air blower in the inner container because it only flows obliquely upward for a very small distance before hitting the inner top wall of the inner container, resulting in the occurrence of air flow dead angle in the area far away from the hot air blower in the inner container, which is not conducive to ensuring the uniform heating of food. CONTENT OF THE UTILITY MODEL

[0004] Therefore, it is necessary to provide a cooking device to solve the above problems, which is beneficial to prevent the occurrence of air flow dead angle in the area far away from the hot air blower in the inner container.

[0005] In order to solve the above problems, the technical scheme of the present application is as follows:

[0006] A cooking device, comprising:

[0007] an inner container, the two sides of the inner container in the length direction are respectively a first side and a second side;

[0008] a hot air machine arranged at the first side and blowing air towards the second side, the hot air machine comprising a fan rotatably arranged in the inner container;

[0009] a heating pipe arranged around the fan or between the fan and the second side; and

[0011] a plurality of first flow guide holes are arranged on the flow guide plate, and a second flow guide hole is arranged on an upper portion of the side baffle, the upper flow guide piece being protruded from an outer side of the upper portion of the side baffle, and a curved through hole being arranged in the upper flow guide piece, the curved through hole being unidirectionally curved and extending from the second flow guide hole towards the second side;

[0012] an opening of the curved through hole away from the first side is an outlet, the outlet is arranged above the flow guide plate, an orientation of the outlet is along an upwardly inclined direction or a horizontal direction, and an included angle between the orientation of the outlet and a horizontal plane is a, a satisfies: a≤30°.

[0013] The cooking device has at least the following beneficial effects:

[0014] The unidirectionally curved curved through hole can reduce the flow resistance of the hot air flow, so that the hot air flow is blown out from the outlet at a high flow rate. The outlet is arranged at a high position, the included angle between the orientation of the outlet and the horizontal plane is small, and the hot air flow is blown out from the outlet at a high flow rate. These three factors are all conducive to the hot air flow blown out from the outlet to flow a large horizontal distance to reach the area of the inner container far away from the hot air machine (i.e. the area close to the second side), thereby preventing the area of the inner container far away from the hot air machine from having a flow dead angle.

[0015] In one of the embodiments, the curved through hole is in a circular arc shape.

[0016] In this way, the flow resistance of the hot air flow in the curved through hole is reduced, thereby reducing the kinetic energy loss of the hot air flow, and the hot air flow blown out from the outlet is conducive to flowing to the area of the inner container far away from the hot air machine.

[0017] In one of the embodiments, the curved through hole is in an involute shape.

[0018] In this way, the flow resistance of the hot air flow in the curved through hole is reduced, and the kinetic energy loss of the hot air flow is reduced, so that the hot air flow blown out of the outlet flows to the area far away from the hot air fan in the inner container.

[0019] In one of the embodiments, the second flow guide hole is only one and is a strip-shaped hole, the length direction of the second flow guide hole is consistent with the width direction of the inner container, and the cross section of the curved through hole matches the cross section of the second flow guide hole in shape and size.

[0020] In this way, more hot air flow is blown out of the second flow guide hole and the curved through hole, and the hot air flow is distributed along the width direction of the inner container to uniformly heat the food.

[0021] In one of the embodiments, the length of the second flow guide hole is greater than or equal to one third of the width of the inner container.

[0022] In this way, the hot air flow blown out of the curved through hole is uniformly distributed along the width direction of the inner container to uniformly heat the food.

[0023] In one of the embodiments, the portion of the side baffle close to the back side of the inner container is provided with a third flow guide hole.

[0024] In this way, a part of the hot air flow flows towards the second side near the back side of the inner container, which is conducive to uniformly heating the food.

[0025] In one of the embodiments, the third flow guide hole is only one and is a strip-shaped hole, and the length direction of the third flow guide hole is consistent with the height direction of the inner container.

[0026] In this way, more hot air flow is blown out of the third flow guide hole, and the hot air flow is distributed along the height direction of the inner container to uniformly heat the food.

[0027] In one of the embodiments, the portion of the side baffle away from the back side of the inner container is provided with a fourth flow guide hole.

[0028] In this way, a part of the hot air flow flows towards the second side near the door body, which is conducive to uniformly heating the food.

[0029] In one of the embodiments, the fourth flow guide hole is only one and is a strip-shaped hole, and the length direction of the fourth flow guide hole is consistent with the height direction of the inner container.

[0030] In this way, more hot air flow is blown out of the fourth flow guide hole, and the hot air flow is distributed along the height direction of the inner container to uniformly heat the food.

[0031] In one of the embodiments, the lower part of the side baffle is provided with a fifth flow guide hole.

[0032] In this way, a part of the hot air flow flows towards the second side at the lower part of the inner container, which is beneficial to uniformly heat the food. BRIEF DESCRIPTION OF DRAWINGS

[0048] Referring to Figures 1 to 7 , the present application provides a cooking apparatus, which comprises a cabinet (not shown in the drawings), an inner container 1, a door (not shown in the drawings), a hot air machine 2 and a heating pipe 3. The inner container 1 is arranged in the cabinet, and food is placed in the inner container 1 for cooking. The door is rotatably / slidably connected to the cabinet to open / close the inner container 1. The length direction (i.e. the X direction in the drawings) of the inner container 1 is divided into a first side 11 and a second side 12. Figure 2 The hot air machine 2 is arranged at the first side 11, and the hot air machine 2 blows air towards the second side 12. The hot air machine 2 comprises a fan 21, which is rotatably arranged in the inner container 1. The heating pipe 3 is arranged around the periphery of the fan 21 (as shown in the drawings) or between the fan 21 and the second side 12. The heating pipe 3 generates heat when it is working, and the air near the heating pipe 3 becomes hot air due to the heat. When the hot air machine 2 is working, the fan 21 pushes the hot air to flow and forms a hot air flow. Figure 4

[0049] Referring to Figure 1 , Figures 3 to 7 , the cooking apparatus further comprises a flow guide cover 4, which comprises a side baffle 41, a flow guide plate 42 and an upper flow guide member 43. The side baffle 41 is arranged at the first side 11 and surrounds the heating pipe 3, and the flow guide plate 42 is arranged at the end of the side baffle 41 away from the first side 11. The side baffle 41, the flow guide plate 42 and the first side 11 jointly enclose a containing space, and the fan 21 and the heating pipe 3 are both arranged in the containing space. The flow guide plate 42 is provided with a plurality of first flow guide holes 421, and the flow guide plate 42 plays the role of the flow guide plate in the prior art. The side baffle 41 is provided with a second flow guide hole 411 on the upper part thereof. The upper flow guide member 43 is arranged on the outside of the upper part of the side baffle 41, and the upper flow guide member 43 is internally provided with a curved through hole 431. The curved through hole 431 is unidirectionally curved to reduce the flow resistance of the hot air flow, which makes the hot air flow blow out of the curved through hole 431 at a high flow rate. The curved through hole 431 extends from the second flow guide hole 411 towards the second side 12 to guide the hot air flow towards the second side 12.

[0050] The opening of the curved through hole 431 away from the first side 11 is an outlet 4311, and the outlet 4311 is located above the flow guide plate 42. The direction of the outlet 4311 is along an upwardly inclined direction or a horizontal direction, and the included angle between the direction of the outlet 4311 and the horizontal plane is α, which satisfies: α≤30°.​

[0051] In this cooking device, the outlet 4311 is positioned high, the angle between the outlet 4311 and the horizontal plane is small, and the hot airflow is blown out from the outlet 4311 at a high speed. These three factors are conducive to the hot airflow blown out from the outlet 4311 traveling a large horizontal distance to reach the area inside the inner liner 1 that is far away from the hot air blower 2 (i.e., the area near the second side 12), thereby preventing the formation of airflow dead zones in the area inside the inner liner 1 that is far away from the hot air blower 2.

[0052] It is worth mentioning that when the first side 11 is the left side of the inner liner 1, if the fan 21 rotates clockwise, the hot airflow above the fan 21 in the accommodating space tends to flow towards the back of the inner liner 1; if the fan 21 rotates counterclockwise, the hot airflow above the fan 21 in the accommodating space tends to flow towards the door. Regardless of whether the fan 21 rotates clockwise or counterclockwise, the hot airflow is corrected in direction due to the constraint of the curved through-hole 431 as it passes through the curved through-hole 431. When the hot airflow is blown out from the outlet 4311, it flows directly towards the second side 12 along the orientation of the outlet 4311, without any tendency to flow towards the back of the inner liner 1 / door. This facilitates the flow of the hot airflow blown out from the outlet 4311 to the area inside the inner liner 1 away from the hot air blower 2.

[0053] When the outlet 4311 is oriented in an upward direction, the hot airflow blown out from the outlet 4311 will hit the top wall of the inner liner 1 after traveling a relatively large horizontal distance (since α≤30°, the kinetic energy of the hot airflow is reduced less after hitting the top wall of the inner liner 1). Then, due to the Coanda effect, it will flow along the top wall of the inner liner 1 towards the second side 12, which is conducive to the hot airflow blown out from the outlet 4311 flowing to the area inside the inner liner 1 away from the hot air blower 2.

[0054] exist Figure 1 In the illustrated embodiment, the first side 11 is the left side of the inner liner 1, and the second side 12 is the right side of the inner liner 1. In other embodiments, the first side 11 can be the right side of the inner liner 1, and the second side 12 can be the left side of the inner liner 1.

[0055] For example, the cooking appliance is an oven / steam oven.

[0056] See Figure 3 and Figure 4 The hot air blower 2 includes a drive motor 22, the base of which is fixed to the housing and / or the first side 11, the output shaft of which passes through the first side 11 and outputs rotational motion, and the fan 21 is fixed to the output shaft of the drive motor 22.

[0057] Preferably, see Figure 1 and Figure 3The curved through hole 431 is in the shape of a circular arc. This is conducive to reducing the flow resistance experienced by the hot air flow during its flow in the curved through hole 431, thereby reducing the kinetic energy loss of the hot air flow, and is conducive to the hot air flow blown out of the outlet 4311 flowing to the area in the inner container 1 that is far away from the hot air fan 2.

[0058] Preferably, in some embodiments, the curved through hole 431 is in the shape of an involute. This is conducive to reducing the flow resistance experienced by the hot air flow during its flow in the curved through hole 431, thereby reducing the kinetic energy loss of the hot air flow, and is conducive to the hot air flow blown out of the outlet 4311 flowing to the area in the inner container 1 that is far away from the hot air fan 2.

[0059] In other embodiments, the curved through hole 431 can also be in the shape of an elliptical arc / parabolic line.

[0060] Referring to Figure 7 , the second flow guide hole 411 is provided only one and is a strip-shaped hole, the length direction of the second flow guide hole 411 is consistent with the width direction of the inner container 1 (i.e. the Y direction in Figure 2 , and the cross section of the curved through hole 431 matches the cross section of the second flow guide hole 411 in shape and size. This is conducive to blowing out more hot air flow from the second flow guide hole 411 and the curved through hole 431, and distributing these hot air flows along the width direction of the inner container 1 to uniformly heat the food.

[0061] Further, the length of the second flow guide hole 411 is greater than or equal to one-third of the width of the inner container 1. This is conducive to uniformly distributing the hot air flow blown out of the curved through hole 431 along the width direction of the inner container 1 to uniformly heat the food.

[0062] Referring to Figure 6 , the portion of the side baffle 41 close to the back side of the inner container 1 is provided with a third flow guide hole 412. This causes a portion of the hot air flow to flow towards the second side 12 near the back side of the inner container 1, which is conducive to uniformly heating the food.

[0063] Referring to Figure 6 , the third flow guide hole 412 is provided only one and is a strip-shaped hole, the length direction of the third flow guide hole 412 is consistent with the height direction of the inner container 1 (i.e. the Z direction in Figure 2 ). This is conducive to blowing out more hot air flow from the third flow guide hole 412, and distributing these hot air flows along the height direction of the inner container 1, to uniformly heat the food.

[0064] Referring to Figure 1 , Figure 3 and Figure 6 , the portion of the side baffle 41 away from the back side of the inner container 1 (i.e. the portion close to the door body) is provided with a fourth flow guide hole 413. This causes a portion of the hot air flow to flow towards the second side 12 near the door body, which is conducive to uniformly heating the food.

[0065] Referring to Figure 6 The fourth flow guide hole 413 is only one and is a strip-shaped hole, and the length direction of the fourth flow guide hole 413 is consistent with the height direction of the inner container 1. This is conducive to blowing more hot air flow from the fourth flow guide hole 413 and distributing the hot air flow along the height direction of the inner container 1, so as to uniformly heat the food.

[0066] Referring to Figure 6 The lower part of the side baffle 41 is provided with a fifth flow guide hole 414. This makes a part of the hot air flow flow toward the second side 12 at the lower part of the inner container 1, which is conducive to uniformly heating the food.

[0067] Referring to Figure 6 The fifth flow guide hole 414 is only one and is a strip-shaped hole, and the length direction of the fifth flow guide hole 414 is consistent with the width direction of the inner container 1. This is conducive to blowing more hot air flow from the fifth flow guide hole 414 and distributing the hot air flow along the width direction of the inner container 1, so as to uniformly heat the food.

[0068] The technical features of the above-described embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not contradict, they should be considered as the scope of the present disclosure.

[0069] The above-described embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the protection scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
