Description

Technical Field

[0001] The utility model relates to the technical field of kitchen utensils, in particular to a baking cooking device. Background Art

[0002] Ovens and steam ovens both belong to baking cooking devices. Such devices generate a circulating hot air flow through a hot air component to heat and cook food materials. The hot air flow first flows out from the hot air component, then passes through the hot air blower baffle into the inner container cavity, and then the hot air flow turns around and returns to the hot air blower baffle, so as to pass through the hot air blower baffle again. When the hot air flow returns to the hot air component, a cycle process ends. After the above cycle process is repeated several times, the hot air flow is discharged from the baking cooking device.

[0003] During the development of baking cooking devices, it is usually desired that the hot air flow can perform multiple rounds of circulation, which can improve the utilization rate of the heat carried by the hot air flow and avoid the increase in power consumption caused by frequent startup of the hot air component for heating. However, the hot air flow absorbs the odor components in the food materials during the circulation process. As the number of circulation times increases, the concentration of the odor components in the hot air flow rises. When the hot air flow is discharged from the baking cooking device, it will bring a strong sense of discomfort to the user. Summary of the Utility Model

[0004] In view of this, the utility model provides a baking cooking device that can reduce the concentration of odor components in the hot air flow and improve the pungency when the hot air flow is discharged.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the specification of the present utility model herein are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0032] The present utility model provides a baking cooking device, which can specifically be an oven, a steam oven, etc. Refer to Figures 1 to 2 , the baking cooking device of the present utility model includes an inner container assembly 10, a hot air blower baffle 20, a back plate 30, and a hot air assembly 50. The hot air blower baffle 20 includes a front side 201 and a rear side 202 arranged opposite to each other. The inner container assembly 10 and the back plate 30 are respectively located on the front side 201 and the rear side 202 of the hot air blower baffle 20. The front side 201 and the inner container assembly 10 enclose to form an inner container cavity 61. A hot air cavity 62 is formed between the rear side 202 and the back plate 30. The hot air blower baffle 20 is provided with an air outlet hole and a return air hole 211. The air outlet hole and the return air hole 211 penetrate through the front side 201 and the rear side 202, thereby connecting the inner container cavity 61 and the hot air cavity 62. The hot air assembly 50 is arranged in the hot air cavity 62. The hot air cavity 62 serves as a place for generating hot air flow, and the inner container cavity 61 is used for placing food materials and serving as a place for heating the food materials with hot air flow to cook the food materials.

[0033] Specifically, the hot air assembly 50 includes a fan 51 rotatably disposed in the hot air chamber 62, and also includes a heating pipe 52 disposed in the hot air chamber 62. The rotation axis of the fan 51 passes through the hot air blower baffle 20. The inner container assembly 10 is a hollow prismatic structure with an inner container channel. The extending direction of the inner container channel is the same as the extending direction of the rotation axis of the fan 51. The hot air blower baffle 20 is located at one end of the inner container channel. Thus, the inner wall surface of the inner container channel and the front side 201 of the hot air blower baffle 20 enclose to form the inner container chamber 61. The other end of the inner container channel forms an inner container opening to facilitate the user to take out or put in the food ingredients into the inner container chamber 61. Refer to Figure 1 , Figures 5 to 6 , the hot air blower baffle 20 includes a return air portion 21 and a baffle portion 22. The return air portion 21 is provided with a return air hole 211. The baffle portion 22 is connected to the outer peripheral edge of the return air portion 21. The return air portion 21 and the baffle portion 22 are parallel or coplanar. The rotation axis of the fan 51 vertically passes through the hot air blower baffle 20. The inner container assembly 10 includes a first side plate 11, a top plate 12, a second side plate 13, and a bottom plate 14 sequentially arranged along the circumferential direction of the rotation axis. The inner wall surface of the inner container channel includes the side of the first side plate 11 facing the second side plate 13, the side of the top plate 12 facing the bottom plate 14, the side of the second side plate 13 facing the first side plate 11, and the side of the bottom plate 14 facing the top plate 12. It can be understood that the inner wall surface of the inner container assembly 10 is the inner wall surface of the inner container channel.

[0034] When using the baking cooking device to bake food ingredients, the hot air assembly 50 is first started and operated. The fan 51 rotates and disturbs the air in the hot air chamber 62 while the heating pipe 52 heats this air, thereby forming a hot air flow. The hot air flow passes through the hot air blower baffle 20 through the air outlet hole and then enters the inner container chamber 61. After flowing a certain distance in the inner container chamber 61, the hot air flow turns around and returns to the hot air blower baffle 20. The returned hot air flow, as the return air flow, passes through the hot air blower baffle 20 from the return air hole 211 and then enters the hot air chamber 62. Then, under the disturbing action of the fan 51, the return air flow becomes the hot air flow again. The hot air flow repeats the above process and conducts multiple rounds of circulation between the hot air chamber 62 and the inner container chamber 61 to heat the food ingredients multiple times. Usually, the return air flow still carries a lot of heat, which means that in most cases, after the return air flow enters the hot air chamber 62, it only needs to be disturbed by the fan 51 again to become the hot air flow again, without being reheated. Only after the hot air flow circulates multiple times and the return air flow returning to the hot air chamber 62 drops below a certain temperature, does this part of the return air flow need to be reheated to become the hot air flow again.

[0035] Therefore, in most cases, the hot air component 50 operates as follows: during a complete food cooking process, the fan 51 continuously rotates to continuously provide power for the circulating flow of the hot air current, and the heating tube 52 starts and operates intermittently. After heating the air in the hot air cavity 62 once, the heating tube 52 stops operating. The hot air current circulates between the hot air cavity 62 and the inner pot cavity 61 multiple times during the period when the heating tube 52 stops operating until the temperature of the air in the hot air cavity 62 and the reflux air current entering the hot air cavity 62 drops below a certain temperature, and then the heating tube 52 operates again. In this way, not only is the heat of the hot air current fully and efficiently utilized, but also the power consumption of the heating tube 52 is reduced. The heating tube 52 does not need to continuously operate for a long time, and it can prevent the fan 51 from being roasted for a long time. After the food cooking is completed, the remaining hot air in the inner pot cavity 61 and the hot air cavity 62 will be discharged from the baking cooking device.

[0036] Since the amount of odor components in the food diffusing into the hot air current will increase with the increase in the number of cycles of the hot air current in the baking cooking device, resulting in a pungent and unpleasant hot air current, the baking cooking device of the present utility model further includes a purification component 40, and at least a part of the purification component 40 is disposed in the hot air cavity 62. In this way, the reflux air current entering the hot air cavity 62 and the air accumulated in the hot air cavity 62 can be filtered by the purification component 40 to remove odor components, so that the concentration of odor components in the newly generated hot air current in the hot air cavity 62 decreases. Finally, through the purification of the hot air current by the purification component 40, the hot air discharged from the baking cooking device is not likely to bring a strong pungent feeling to the user, reducing the impact of the discharged hot air on the environment.

[0037] In some embodiments, the purification component 40 includes an odor removal module 41 located in the hot air cavity 62. Refer to Figures 2 to 3 , the odor removal module 41 is disposed on the outer peripheral side of the fan 51. The fan 51 includes a main body part and fan blades connected to the main body part. The main body part is disposed opposite to the air return part 21. The hot air component 50 further includes a driving member connected to the main body part of the fan 51. The driving member can drive the fan 51 to rotate around a preset rotation center, and the preset rotation center is the rotation axis of the fan 51. The outer peripheral side of the fan 51 includes the ends of the fan blades relatively far from the preset rotation center. When the fan 51 rotates, it will suck air to make the air approach the main body part along the extension direction of the preset rotation center. Subsequently, the sucked air is pushed by the fan blades to accelerate, and finally these airs are thrown out of the ends of the fan 51 under the centrifugal force to form an air current. Therefore, the outer peripheral side of the fan 51 composed of the ends of the fan blades is the air outlet part of the fan 51. After the air current leaves the fan 51, it will flow to the odor removal module 41 and the odor components will be filtered by the odor removal module 41, and then these air currents will blow towards the inner pot cavity 61 as hot air currents.

[0038] Specifically, refer to Figures 3 to 4, the heating pipe 52 is located on the outer peripheral side of the fan 51, and the deodorization module 41 is located on the side of the heating pipe 52 relatively far from the fan 51. With such an arrangement, after the air flow is thrown out of the fan 51, it first flows through the heating pipe 52 and is heated by the heating pipe 52 to become a hot air flow, and then the hot air flow flows through the deodorization module 41 and the odor components are filtered out by the deodorization module 41. That is to say, the deodorization module 41 purifies the air flow carrying heat, and a higher temperature can improve the efficiency of the deodorization module 41 in filtering out odor components. In some embodiments, the deodorization module 41 can chemically react with the odor components, and the hot air flow flowing through the deodorization module 41 can increase the chemical reaction rate between the deodorization module 41 and the odor components and catalyze the reaction; in other embodiments, the deodorization module 41 can physically adsorb and intercept the odor components, and the temperature of the hot air flow can increase the activity of the deodorization module 41, thereby improving the interception and adsorption ability of the deodorization module 41 for the odor components.

[0039] Optionally, referring to Figure 4 , the heating pipe 52 includes a closed-loop pipe section that surrounds the fan 51 circumferentially along the rotation axis of the fan 51. The deodorization module 41 has a closed-loop structure, and the deodorization module 41 surrounds the outer peripheral side of the closed-loop pipe section circumferentially along the rotation axis of the fan 51, that is, the deodorization module 41 itself has a hollow area, and both the fan 51 and the closed-loop pipe section are accommodated in the hollow area of the deodorization module 41. Preferably, both the closed-loop pipe section and the deodorization module 41 are circular ring structures, and the closed-loop pipe section, the deodorization module 41 and the fan 51 are coaxially arranged. The rotation axis of the fan 51 coincides with the axis of the closed-loop pipe section and also coincides with the axis of the deodorization module 41. In this way, the air thrown out from each radial direction of the fan 51 can be heated by the heating pipe 52, and the air thrown out from each radial direction of the fan 51 can be filtered out of the odor components by the deodorization module 41, improving the purification effect and preventing some hot air flows from missing the deodorization module 41.

[0040] Optionally, referring to Figures 3 to 4 , both ends of the deodorization module 41 are respectively abutted against the rear side 202 of the hot air blower baffle 20 and the side of the back plate 30 facing the hot air blower baffle 20. Therefore, one end of the hollow area of the deodorization module 41 is covered by the hot air blower baffle 20, and the other end of the hollow area of the deodorization module 41 is covered by the back plate 30. Correspondingly, the deodorization module 41 is provided with ventilation holes 411, and the ventilation holes 411 penetrate through the side of the deodorization module 41 relatively close to the fan 51 and also penetrate through the side of the deodorization module 41 relatively far from the fan 51.

[0041] Thus, the odor removal module 41, the hot air blower baffle 20 and the back plate 30 jointly enclose a closed space area. The closed space area is only communicated with the inner tank cavity 61 through the return air holes 211, and the closed space area is only communicated with the hot air cavity 62 outside the odor removal module 41 through the ventilation holes 411. This means that the reflux air flow entering the closed space area and the air accumulated in the closed space area can only diffuse to the hot air cavity 62 area outside the odor removal module 41 through the ventilation holes 411, ensuring that all the hot air flows thrown out by the fan 51 can flow through the odor removal module 41 so that the odor components can be fully filtered by the odor removal module 41, significantly improving the odor removal and purification effect.

[0042] As Figures 4 to 5 shown, the ventilation holes 411 may specifically be mesh holes extending along the radial direction of the odor removal module 41. The mesh holes are uniformly distributed along the circumferential direction of the odor removal module 41. One end of each ventilation hole 411 relatively close to the rotation axis of the fan 51 penetrates the inner circumferential side of the odor removal module 41. The inner circumferential side of the odor removal module 41 is the side of the odor removal module 41 relatively close to the fan 51 and the heating pipe 52. The other end of each ventilation hole 411 relatively far from the rotation axis of the fan 51 penetrates the outer circumferential side of the odor removal module 41. The outer circumferential side of the odor removal module 41 is the other side of the odor removal module 41 relatively far from the fan 51 and the heating pipe 52. Thus, the number of the ventilation holes 411 is large and they are densely distributed. The inner wall surface of the ventilation holes 411 serves as the main surface for the odor removal module 41 to filter odor components, significantly increasing the contact area between the odor removal module 41 and the hot air flow.

[0043] Referring to Figures 1 to 3 、 Figures 6 to 7 In some embodiments, a part of the hot air blower baffle 20 protrudes relative to the back plate 30 along the rotation axis of the fan 51 and extends into the inner tank channel, so that at least the baffle part 22 is located in the inner tank channel. The hot air blower baffle 20 further includes a convex edge part. The convex edge part is bent and connected to the outer peripheral edge of the baffle part 22 and protrudes from the side of the baffle part 22 facing the back plate 30. The end of the convex edge part relatively far from the outer peripheral edge of the baffle part 22 is connected to the back plate 30. A gap is provided between the convex edge part and the inner wall surface of the inner tank channel. The air outlet holes include side air outlet holes 24 opened on the convex edge part. The openings of the side air outlet holes 24 face the inner wall surface of the inner tank channel. Preferably, the convex edge part is a closed-loop structure extending along the outer peripheral edge of the baffle part 22. The convex edge part surrounds the baffle part 22 and circumferentially surrounds the hot air assembly 50 along the rotation axis of the fan 51. The outer circumferential side of the odor removal module 41 faces the inner peripheral wall of the convex edge part.

[0044] Specifically, as Figure 1 、 Figures 5 to 7As shown, the outer periphery of the baffle part 22 is approximately octagonal, including a first side edge, a first bevel edge, a top edge, a second bevel edge, a second side edge, a third bevel edge, a bottom edge, and a fourth bevel edge that are sequentially arranged along the circumferential direction of the rotation axis of the fan 51; the convex edge part includes a first side convex edge 231 bent and connected to the first side edge, a first bevel convex edge 235 bent and connected to the first bevel edge, a top convex edge 232 bent and connected to the top edge, a second bevel convex edge 236 bent and connected to the second bevel edge, a second side convex edge 233 bent and connected to the second side edge, a third bevel convex edge 237 bent and connected to the third bevel edge, a bottom convex edge 234 bent and connected to the bottom edge, and a fourth bevel convex edge 238 bent and connected to the fourth bevel edge. One side of the first side plate 11 facing the second side plate 13 is spaced apart and facing each other with the first side convex edge 231, one side of the top plate 12 facing the bottom plate 14 is spaced apart and facing each other with the top convex edge 232, one side of the second side plate 13 facing the first side plate 11 is spaced apart and facing each other with the second side convex edge 233, and one side of the bottom plate 14 facing the top plate 12 is spaced apart and facing each other with the bottom convex edge 234. The two ends of the first bevel convex edge 235 are respectively connected to the first side convex edge 231 and the top convex edge 232, and the side of the first bevel convex edge 235 away from the hot air assembly 50 faces the included angle between the first side plate 11 and the top plate 12. The two ends of the second bevel convex edge 236 are respectively connected to the top convex edge 232 and the second side convex edge 233, and the side of the second bevel convex edge 236 away from the hot air assembly 50 faces the included angle between the top plate 12 and the second side plate 13. The two ends of the third bevel convex edge 237 are respectively connected to the second side convex edge 233 and the bottom convex edge 234, and the side of the third bevel convex edge 237 away from the hot air assembly 50 faces the included angle between the second side plate 13 and the bottom plate 14. The two ends of the fourth bevel convex edge 238 are respectively connected to the bottom convex edge 234 and the first side convex edge 231, and the side of the fourth bevel convex edge 238 away from the hot air assembly 50 faces the included angle between the bottom plate 14 and the first side plate 11.

[0045] Optionally, as Figure 1 , Figures 6 to 7As shown, the side air outlet holes 24 are formed in any one or more of the first side convex edge 231, the top convex edge 232, the second side convex edge 233 and the bottom convex edge 234; no side air outlet holes 24 are formed in the first inclined convex edge 235, the second inclined convex edge 236, the third inclined convex edge 237 and the fourth inclined convex edge 238. With such an arrangement, it not only does not affect the hot air flow passing through the hot air blower baffle 20 and blowing into the inner tank cavity 61, but also can inhibit the hot air flow from flowing into the dead corner areas on the inner wall surface of the inner tank channel, thereby helping to increase the number of times the hot air flow circulates between the inner tank cavity 61 and the hot air cavity 62. The dead corner areas on the inner wall surface include the angles between the first side plate 11 and the top plate 12, between the top plate 12 and the second side plate 13, between the second side plate 13 and the bottom plate 14, and between the bottom plate 14 and the first side plate 11. Especially, for example, in the case where an exhaust port is formed in the area of the top plate 12 near the hot air blower baffle 20 and the first side plate 11, inhibiting the hot air flow from flowing into the dead corner areas on the inner wall surface of the inner tank channel can prevent the hot air flow from flowing towards the exhaust port, preventing the hot air flow from being prematurely discharged from the exhaust port of the baking cooking device, thereby increasing the number of times the hot air flow circulates.

[0046] Optionally, in some embodiments, the air outlet holes further include direct air outlet holes formed in the baffle part 22. The hot air flow passing through the direct air outlet holes can directly blow into the inner tank cavity 61 and then directly flow towards the end of the inner tank channel away from the hot air blower baffle 20. In contrast, due to the wall attachment effect of the fluid, the hot air flow passing through the side air outlet holes 24 mainly flows along the inner wall surface of the inner tank channel. Therefore, the hot air flow passing through the direct air outlet holes is responsible for directly baking the food ingredients, while the hot air flow passing through the side air outlet holes 24 is more used to form a heat flow field occupying the inner tank cavity 61, and the food ingredients are surrounded by the heat flow field. The above two hot air flows cooperate with each other to ensure that the food ingredients are fully heated and cooked. The side air outlet holes 24 formed in the convex edge part are more convenient for the hot air flow to pass through. After the hot air flow is thrown out by the fan 51, it has a radial velocity vector flowing radially along the rotation axis of the fan 51. By virtue of the radial velocity vector, most of the hot air flow directly blows towards the inner side of the convex edge part facing the hot air assembly 50, and then directly passes through the side air outlet holes 24 until it reaches the inner wall surface of the inner tank channel. Of course, the direct air outlet holes on the baffle part 22 can also be cancelled.

[0047] Further, whether the air outlet holes are the direct air outlet holes formed in the baffle part 22, the side air outlet holes 24 formed in the convex edge part, or both the direct air outlet holes and the side air outlet holes 24, the shortest distance from the air outlet holes to the rotation axis is not less than the longest distance from the deodorization module 41 to the rotation axis. Refer to Figures 2 to 3 , the distance from the side air outlet holes 24 formed in the convex edge part to the rotation axis of the fan 51 is greater than the distance from the outer peripheral side of the deodorization module 41 to the rotation axis of the fan 51. If the front side 201 of the hot air blower baffle 20 is observed in the line-of-sight direction parallel to the rotation axis of the fan 51, as Figure 1As shown in the figure, the projection of the air outlet hole on the plane parallel to the hot air blower baffle 20 is the air outlet opening projection, the projection of the deodorization module 41 on the plane parallel to the hot air blower baffle 20 is the deodorization position projection, and the projection of the return air hole 211 on the plane parallel to the hot air blower baffle 20 is the return air opening projection. It is stipulated that the plane parallel to the hot air blower baffle 20 is parallel to the hot air blower baffle 20 and perpendicular to the rotation axis of the fan 51. Then, the deodorization position projection is a closed loop figure, the air outlet opening projection is entirely located outside the deodorization position projection, and the return air opening projection is entirely located inside the deodorization position projection. In this way, all the return airflows entering the hot air cavity 62 through the return air hole 211 pass through the deodorization module 41 and then reach the outer peripheral side of the deodorization module 41, and the hot airflows blown from the air outlet hole into the inner tank cavity 61 all pass through the deodorization module 41.

[0048] The baking and cooking device of the present utility model adopts the form of arranging the deodorization module 41 in the hot air cavity 62. When the user takes out the food from the inner tank cavity 61 or puts the food into the inner tank cavity 61, neither will be interfered by the deodorization module 41, and at the same time, the situation that the deodorization module 41 is contaminated by the food is also avoided, which can enable the deodorization module 41 to maintain cleanliness for a longer time without the need for frequent cleaning or replacement.

[0049] The technical features of the above-described embodiments can be combined arbitrarily.
