AI Technical Summary
In the rear part of the oven cavity, away from the hot air blower, there are often dead air zones that can cause uneven heating of food.
A cooking device was designed in which a hot air blower is located on one side of the inner pot along its length and far from the back side. It adopts an arc-shaped connecting side, a flow guide and a flow guide plate structure. Through the combination of flow guide holes and a straightening plate, the hot airflow is guided to flow along the connecting side to the back side of the inner pot. The Coanda effect is used to prevent airflow dead zones, and the curved through holes reduce the kinetic energy loss of the hot airflow to the door.
This effectively prevents airflow dead zones in the rear of the inner liner, which is far from the hot air blower, ensuring even heating of food and reducing kinetic energy loss of hot airflow during its flow.

Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of kitchen utensils, in particular to a cooking device. BACKGROUND
[0002] In an oven, the heat blower and the flow guide plate work together to optimize the circulation and distribution of hot air in the inner container, so as to ensure uniform heating and cooking effect of food. The heat 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 flow guide plate is usually located directly in front of the outlet of the heat blower, and a plurality of flow guide holes are arranged on the flow guide plate. The flow guide plate guides and distributes the flow direction of the hot air flow through these flow guide 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 uniform heating of food.
[0003] In the existing oven, if only one heat blower is arranged in the inner container, the heat blower is usually arranged at one side of the length direction of the inner container (i.e. the left side or the right side of the inner container). Since the inner container of the existing oven is generally square, the distance from the heat blower to the door body and the distance from the heat blower to the back side of the inner container are approximately equal. In this way, there is a proper distance between the heat blower and the door body, and there is also a proper distance between the heat blower and the back side of the inner container. Correspondingly, there is a proper distance between the flow guide hole close to the door body and the door body, and there is also a proper distance between the flow guide hole close to the back side of the inner container and the back side of the inner container. In this way, the hot air flow blown out from the heat blower and obliquely blown to the door body and the back side of the inner container through the flow guide hole has a proper flow space, and these hot air flows can fully flow to the areas far away from the heat blower in the inner container, respectively, and the areas far away from the heat blower in the inner container will not appear air flow dead angle.
[0004] However, the inner container of some ovens is not square and the space at the rear part of these inner containers is narrow, so the heat blower can only be arranged at the front part of the inner container. In the case where the heat blower is arranged at one side of the length direction of the inner container, since the distance between the back side of the inner container and the heat blower is large, the distance between the part far away from the heat blower at the rear part of the inner container and the heat blower is large. The hot air flow blown out from the heat blower and obliquely blown to the back side of the inner container through the flow guide hole is difficult to reach the part far away from the heat blower at the rear part of the inner container, and the part far away from the heat blower at the rear part of the inner container will appear air flow dead angle, which is not conducive to ensuring uniform heating of food. CONTENT OF THE UTILITY MODEL
[0005] Therefore, it is necessary to provide a cooking device to solve the above problems. In the case where the heat blower is arranged at one side of the length direction and far away from the back side of the inner container, the cooking device can still prevent the part far away from the heat blower at the rear part of the inner container from appearing air flow dead angle.
[0006] In order to solve the above problems, the technical scheme of the present application is as follows:
[0007] A cooking device comprises:
[0008] A liner having an opening for food to enter or exit, the liner having a back side opposite to the opening, the liner having a first side and a second side at two lengthwise ends of the liner, the liner having a connecting side extending from the first side towards the back side, the connecting side being arc-shaped, the first side and the back side being connected by the arc-shaped connecting side;
[0009] A hot air machine arranged at the first side and blowing air towards the second side, the hot air machine being arranged at a distance from the back side greater than a distance from the opening, the hot air machine comprising a fan rotatably arranged in the liner;
[0010] A heating pipe arranged around the fan or between the fan and the second side; and
[0011] A flow guide cover comprising a side baffle and a flow guide plate, the side baffle being arranged at the first side and surrounding the heating pipe, the flow guide plate being arranged at an end of the side baffle away from the first side, the side baffle, the flow guide plate and the first side together defining a containing space, the fan and the heating pipe being arranged in the containing space;
[0012] The flow guide plate is provided with a plurality of first flow guide holes, and a portion of the side baffle close to the back side is provided with second flow guide holes, the second flow guide holes being arranged opposite to the connecting side.
[0013] The cooking device has at least the following beneficial effects:
[0014] In the cooking device, the hot air stream blown out of the second flow guide holes first flows to the connecting side, then flows to the back side of the liner under the guidance of the connecting side, and then flows towards the second side along the back side of the liner due to the Coanda effect, so as to reach the portion of the back side of the liner far away from the hot air machine, thereby preventing the occurrence of a dead air zone in the portion of the back side of the liner far away from the hot air machine. Therefore, in the case that the hot air machine is arranged at one lengthwise end of the liner and is far away from the back side of the liner, the cooking device can still prevent the occurrence of a dead air zone in the portion of the back side of the liner far away from the hot air machine.
[0015] In one embodiment, the connecting side is circular arc-shaped.
[0016] In this way, the flow resistance of the hot air stream in the process of flowing along the connecting side is reduced, so that the kinetic energy loss of the hot air stream is reduced, and the hot air stream blown out of the second flow guide holes is facilitated to flow to the portion of the back side of the liner far away from the hot air machine.
[0017] In one embodiment, the second flow guide holes are located above half the height of the back side.
[0018] In this way, the hot air flow can be ensured to reach the rear part of the inner container far away from the hot air blower.
[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 height direction of the inner container, and the length of the second flow guide hole is greater than or equal to one fourth of the height of the inner container.
[0020] In this way, more hot air flow can be blown out of the second flow guide hole, and more hot air flow can be made to reach the rear part of the inner container far away from the hot air blower.
[0021] In one of the embodiments, the side baffle is provided with a correction plate, the correction plate is arranged directly below or flush with the lower edge of the second flow guide hole, and the height difference between the correction plate and the lower edge of the second flow guide hole is less than or equal to 5 mm, and the correction plate extends along the horizontal direction towards the back side.
[0022] In this way, even if the hot air flow blown out of the second flow guide hole has a downward flow bias, the hot air flow can be corrected to flow horizontally towards the second side along the flow direction of the correction plate when flowing through the correction plate, which is beneficial to make the hot air flow blown out of the second flow guide hole flow to the rear part of the inner container far away from the hot air blower.
[0023] In one of the embodiments, the second flow guide hole and the correction plate are both provided with a plurality of the second flow guide holes, each of the second flow guide holes is arranged in sequence from top to bottom, and each of the second flow guide holes is correspondingly provided with a correction plate below.
[0024] In this way, the hot air flow expected to flow to the rear part of the inner container far away from the hot air blower flows out of the plurality of second flow guide holes, the hot air flow distributed to each of the second flow guide holes is relatively small, and the hot air flow blown out of the second flow guide hole can be fully corrected by the correction plate.
[0025] In one of the embodiments, the part of the side baffle close to the opening is provided with a third flow guide hole; the flow guide cover further comprises a side flow guide piece, the side flow guide piece is protruded outwardly from the part of the side baffle close to the opening, the side flow guide piece is internally provided with a curved through hole, the curved through hole is unidirectionally curved and extends from the third flow guide hole towards the second side; the opening of the curved through hole far away from the first side is an outlet, and the outlet is directed along the obliquely forward direction.
[0026] In this way, the angle between the flow direction of the hot air flow blown to the opening (in the working process of the cooking device, the door body closes the opening, so the hot air flow is blown to the door body) and the inner wall of the door body is reduced, so that the hot air flow blown by the hot air blower and obliquely blown to the door body through the third flow guide hole and the curved through hole flows a greater distance before hitting the door body, which is beneficial to the hot air flow flowing a greater horizontal distance, and the kinetic energy of the hot air flow hitting the door body is reduced less, so that the hot air flow can still flow a greater horizontal distance along the door body after hitting the door body to reach the area far from the hot air blower in the front of the inner container, preventing the area far from the hot air blower in the front of the inner container from having a flow dead angle.
[0027] In one of the embodiments, the edge of the opening is located in a first plane, and the angle between the orientation of the outlet and the first plane is α, and α satisfies: α≤30°.
[0028] In this way, the angle between the flow direction of the hot air flow blown to the opening (in the working process of the cooking device, the door body closes the opening, so the hot air flow is blown to the door body) and the inner wall of the door body is reduced, so that the hot air flow blown by the hot air blower and obliquely blown to the door body through the third flow guide hole and the curved through hole flows a greater distance before hitting the door body, which is beneficial to the hot air flow flowing a greater horizontal distance, and the kinetic energy of the hot air flow hitting the door body is reduced less, so that the hot air flow can still flow a greater horizontal distance along the door body after hitting the door body to reach the area far from the hot air blower in the front of the inner container, preventing the area far from the hot air blower in the front of the inner container from having a flow dead angle.
[0029] In one of the embodiments, the bottom wall of the curved through hole is located in the same horizontal plane.
[0030] In this way, the hot air flow blown out of the third flow guide hole is corrected to flow in a certain direction when passing through the curved through hole due to the constraint of the bottom wall of the curved through hole. The hot air flow blown out of the curved through hole flows in a horizontal direction without being biased to flow downward, which is beneficial to the hot air flow flowing to the area far from the hot air blower in the front of the inner container.
[0031] In one of the embodiments, the curved through hole is in the shape of a circular arc.
[0032] 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 of the curved through hole flows to the area far from the hot air blower in the front of the inner container.

[0051] See Figures 1 to 9 This application provides a cooking device, which includes a housing (not shown in the figure), an inner pot 1, a door, a hot air blower 2, and a heating element 3. The inner pot 1 has an opening 15 for food to enter and exit, and the food is cooked inside the inner pot 1. The door is rotatably / slidably connected to the housing to open and close the opening 15. The side of the inner pot 1 opposite to the opening 15 is the back side 13, and the length direction of the inner pot 1 (i.e., Figure 2 The inner liner 1 has a first side 11 and a second side 12 on either side (in the X direction). The inner liner 1 has a connecting side 14 located between the first side 11 and the back side 13. The connecting side 14 extends from the first side 11 toward the back side 13 and is arc-shaped, forming an arc transition between the first side 11 and the back side 13. A hot air blower 2 is located on the first side 11 and blows air toward the second side 12. The distance from the hot air blower 2 to the back side 13 is greater than the distance to the opening 15; in other words, the hot air blower 2 is located at a greater distance from the back side 13 of the inner liner 1. The hot air blower 2 includes a fan 21, which is rotatably disposed within the inner liner 1. A heating pipe 3 is arranged around the periphery of the fan 21 (e.g., ...). Figure 6 (As shown) or located between fan 21 and the second side 12. When the heating tube 3 is working, it generates heat, and the air near the heating tube 3 becomes hot air due to the heat. When the hot air blower 2 is working, the fan 21 pushes the hot air to flow and form a hot airflow.
[0052] See Figure 1 and Figure 4 The cooking device also includes a flow guide 4, which comprises a side baffle 41 and a flow guide plate 42. The side baffle 41 protrudes from the first side 11 and surrounds the heating tube 3. The flow guide plate 42 is located 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 together enclose an accommodating space, within which the fan 21 and the heating tube 3 are located. The flow guide plate 42 has multiple first flow guide holes 421, and the flow guide plate 42 functions as a flow guide plate in the prior art. (See reference...) Figure 4 A second guide hole 411 is provided on the part of the side baffle 41 near the back side 13, and the second guide hole 411 is arranged opposite to the connecting side 14.
[0053] In the cooking apparatus, the hot air stream blown out from the second flow guide hole 411 first flows to the connecting side 14, then flows to the back side 13 of the inner container 1 under the guidance of the connecting side 14, and then flows towards the second side 12 along the back side 13 of the inner container 1 due to the Coanda effect, so as to reach the portion of the back of the inner container 1 far away from the hot air blower 2, thereby preventing the occurrence of air flow dead angle in the area of the inner container 1 far away from the hot air blower 2. Therefore, in the case that the hot air blower 2 is arranged at one side in the length direction and far away from the back side 13 of the inner container 1, the cooking apparatus can still prevent the occurrence of air flow dead angle in the portion of the back of the inner container 1 far away from the hot air blower 2.
[0054] In Figure 1 the illustrated embodiment, the first side 11 is the left side of the inner container 1, and the second side 12 is the right side of the inner container 1. In other embodiments, the first side 11 can be the right side of the inner container 1, and the second side 12 can be the left side of the inner container 1.
[0055] Exemplarily, the cooking apparatus is an oven / steam oven.
[0056] Referring to Figure 6 and Figure 7 , the hot air blower 2 comprises a driving motor 22, a base of the driving motor 22 is fixedly arranged on the box body and / or the first side 11, an output shaft of the driving motor 22 penetrates through the first side 11 and outputs rotary motion, and the fan 21 is fixedly arranged on the output shaft of the driving motor 22.
[0057] Referring to Figure 1 , Figure 3 and Figure 4 , in some embodiments, the connecting side 14 is in the shape of a circular arc. This is advantageous to reduce the flow resistance suffered by the hot air flow during the flowing along the connecting side 14, thereby reducing the kinetic energy loss of the hot air stream, and facilitating the hot air stream blown out from the second flow guide hole 411 to flow to the portion of the back of the inner container 1 far away from the hot air blower 2.
[0058] In other embodiments, the connecting side 14 can also be in the shape of an elliptical arc / parabolic arc.
[0059] In Figure 1 the illustrated embodiment, the hot air blower 2 is arranged at the left side of the inner container 1, and if the fan 21 rotates clockwise, the hot air stream blown out from the second flow guide hole 411 has a biasing tendency to flow downwards, the hot air stream flows obliquely downwards along the back side 13 of the inner container 1, and in order to ensure that the hot air stream reaches the portion of the back of the inner container 1 far away from the hot air blower 2, the second flow guide hole 411 is located above the half of the height of the back side 13.
[0060] In Figure 4 the illustrated embodiment, the second flow guide hole 411 is only one and is a strip-shaped hole, and the length direction of the second flow guide hole 411 is parallel to the height direction of the inner container 1 (i.e. Figure 2The length of the second flow guide hole 411 is greater than or equal to one fourth of the height of the inner container 1. This is conducive to blowing more hot air flow from the second flow guide hole 411 and conducive to making more hot air flow reach the portion of the rear of the inner container 1 far from the hot air fan 2.
[0061] Referring to Figure 10 In other embodiments, the side baffle 41 is provided with a correction plate 44, the correction plate 44 is arranged directly below or flush with the lower edge of the second flow guide hole 411, and the height difference between the correction plate 44 and the lower edge of the second flow guide hole 411 is less than or equal to 5 mm, and the correction plate 44 extends along the horizontal direction towards the back side 13. In this way, even if the hot air flow blown out of the second flow guide hole 411 has a downward flow bias, the hot air flow will be corrected to flow horizontally towards the second side 12 along the flow direction of the correction plate 44 after flowing through the correction plate 44, which is conducive to the hot air flow blown out of the second flow guide hole 411 flowing to the portion of the rear of the inner container 1 far from the hot air fan 2.
[0062] In Figure 10 In the embodiments shown, the second flow guide hole 411 and the correction plate 44 are both provided with a plurality of second flow guide holes 411 arranged one after another from top to bottom, and one correction plate 44 is arranged below each flow guide hole. In this way, the hot air flow expected to flow to the portion of the rear of the inner container 1 far from the hot air fan 2 flows out of the plurality of second flow guide holes 411, and the hot air flow distributed to each second flow guide hole 411 is relatively small, which is conducive to the hot air flow blown out of the second flow guide hole 411 being fully corrected by the correction plate 44.
[0063] For steam ovens with a narrow rear portion of the inner container 1 and a small width of the inner container 1, the hot air fan 2 is arranged too close to the door body in the front area of the inner container 1, resulting in the hot air flow blown out of the hot air fan 2 and obliquely blown towards the door body via the flow guide hole only flowing a small distance before hitting the door body. The kinetic energy of the hot air flow is reduced after hitting the door body. Therefore, in such steam ovens, the hot air flow blown out of the hot air fan 2 and obliquely blown towards the door body via the flow guide hole is difficult to flow to the area of the front of the inner container 1 far from the hot air fan 2, resulting in a flow dead angle in the area of the front of the inner container 1 far from the hot air fan 2, which is not conducive to ensuring uniform heating of food. In order to solve this technical problem, referring to Figure 9A third guide hole 412 is provided on the portion of the side baffle 41 near the opening 15. The guide shroud 4 also includes a side guide member 43, which protrudes from the outer side of the portion of the side baffle 41 near the opening 15. The side guide member 43 has a curved through hole 431, which is unidirectionally curved and extends from the third guide hole 412 toward the second side 12. The opening 15 of the curved through hole 431 away from the first side 11 is the outlet 4311, and the outlet 4311 is oriented in a forward-sloping direction. The side guide 43 reduces the angle between the direction of the hot airflow blowing toward the opening 15 (the door is closed during the operation of the cooking equipment, so blowing toward the opening 15 is blowing toward the door) and the inner wall of the door. This allows the hot airflow blown out by the hot air blower 2 and directed toward the door via the third guide hole 412 and the curved through hole 431 to travel a greater distance before hitting the door. This facilitates a greater horizontal distance for the hot airflow. Moreover, the hot airflow experiences less kinetic energy reduction after hitting the door. As a result, the hot airflow can still travel a greater horizontal distance along the door to reach the area in front of the inner liner 1 away from the hot air blower 2, preventing dead airflow zones in the area in front of the inner liner 1 away from the hot air blower 2.
[0064] The edge of the opening 15 is located within the first plane, and the angle between the orientation of the outlet 4311 and the first plane is α. Preferably, α satisfies: α≤30°. In this way, the angle between the flow direction of the hot airflow blowing obliquely from the curved through-hole 431 towards the door and the door is small. This is beneficial because the hot airflow travels a greater distance before hitting the door, which is beneficial because the hot airflow travels a greater horizontal distance. This is beneficial because it reduces the kinetic energy loss of the hot airflow after hitting the door, and it is beneficial because the hot airflow travels a greater horizontal distance along the door after hitting the door, thus reaching the area at the front of the inner liner 1 away from the hot air blower 2. This is beneficial because it prevents the formation of airflow dead zones in the area at the front of the inner liner 1 away from the hot air blower 2.
[0065] exist Figure 1 In the illustrated embodiment, the hot air blower 2 is located on the left side of the inner liner 1. If the fan 21 rotates counterclockwise, the hot airflow blown out from the third guide hole 412 has a downward bias. (See also...) Figure 8 and Figure 9 Preferably, the bottom wall of the curved through-hole 431 is located in the same horizontal plane. In this way, the hot airflow blown out from the third guide hole 412 is corrected in direction by the constraint of the bottom wall of the curved through-hole 431 as it passes through the curved through-hole 431. The hot airflow will flow horizontally when it is blown out from the curved through-hole 431, and there is no downward bias. This is conducive to the hot airflow flowing to the front of the inner liner 1 away from the hot air blower 2.
[0066] See Figure 4 , Figure 8 and Figure 9, the curved through hole 431 is in the shape of a circular arc. This is conducive to reducing the flow resistance of the hot air flow during the flow in the curved through hole 431, thereby reducing the kinetic energy loss of the hot air flow, and facilitating the hot air flow blown out of the curved through hole 431 to flow to the area of the inner container 1 far away from the hot air fan 2.
[0067] In other embodiments, the curved through hole 431 can also be in the shape of an involute / elliptical arc / parabolic curve.
[0068] Referring to Figure 9 , the third flow guide hole 412 is only one and is a strip-shaped hole, the length direction of the third flow guide hole 412 is consistent with the width direction of the inner container 1, and the length of the third flow guide hole 412 is greater than or equal to one fourth of the height of the inner container 1, 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 third flow guide hole 412 and the curved through hole 431, so that more hot air flow flows to the area of the front of the inner container 1 far away from the hot air fan 2.
[0069] The technical features of the above-mentioned embodiments can be combined in any way. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described, but as long as the combination of the technical features does not exist contradictory, it should be considered as the scope of the present application.
[0070] The above-mentioned embodiments only express several embodiments 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, a number of modifications and improvements can be made, which are within the scope of protection of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
