Description

Technical Field

[0001] The utility model relates to the technical field of cooking appliances, in particular to a steam oven. Background Art

[0002] In the existing built-in steam oven, the oven door usually opens by flipping downwards. When the user opens the oven door during the cooking process to check the cooking condition of the food, the steam in the cooking cavity will escape upwards, and part of the steam will condense on the upper decorative plate of the steam oven and the upper cabinet panel above, affecting the user experience. And after a long time, it may also cause mildew, deformation and other conditions on the upper decorative plate and the upper cabinet panel above. Summary of the Utility Model

[0003] Based on this, it is necessary to provide a steam oven aiming at the above problems to reduce the steam escaping upwards when the oven door is opened.

[0004] The utility model provides a steam oven, including: an inner container, provided with a cooking cavity and an opening communicated with the cooking cavity; a hot air blower, arranged outside the inner container and used for conveying hot air to the cooking cavity; a blowing assembly, arranged at the top of the inner container, the blowing assembly is provided with a blowing cavity and a blowing port communicated with the blowing cavity, the orientation of the blowing port is the same as that of the opening, the blowing assembly includes a fan rotatably arranged in the blowing cavity, and the fan faces the blowing port; and a transmission assembly, arranged outside the inner container and capable of linking the hot air blower and the fan.

[0005] In the above steam oven, when the transmission assembly links the hot air blower and the fan, the fan can rotate synchronously with the hot air blower to form an air flow towards the blowing port in the blowing cavity. When the user opens the oven door to observe the cooking condition of the food in the cooking cavity during the cooking process, the steam in the cooking cavity will escape from the opening, and the air flow blown out from the blowing port can blow the steam escaping from the opening outwards, avoiding the steam flowing upwards and condensing on the upper decorative plate of the steam oven and the upper cabinet panel above, ensuring the normal use of the user, and at the same time, it can also avoid mildew, deformation and other conditions on the upper decorative plate and the upper cabinet panel above after a long time; moreover, by using the original hot air blower in the steam oven to drive the fan to rotate, additional driving elements can be saved, avoiding occupying too much space above the inner container and reducing the cost.

[0006] In one embodiment, the transmission assembly includes a first transmission shaft and a second transmission shaft that extend along a preset axis and are capable of rotating around the preset axis. One of the first transmission shaft and the second transmission shaft is in transmission cooperation with the fan, and the other is in transmission cooperation with the hot air blower. The transmission assembly further includes a first clutch member and a second clutch member respectively disposed at the facing ends of the first transmission shaft and the second transmission shaft. At least one of the first transmission shaft and the second transmission shaft is capable of sliding along the preset axis so that the first clutch member contacts / separates from the second clutch member.

[0007] With such a setting, it is possible to control the contact or separation of the first clutch member and the second clutch member according to actual needs, thereby controlling whether the fan rotates, and avoiding the influence on its service life due to the long-term operation of the fan.

[0008] In one embodiment, the transmission assembly further includes a control valve. The control valve is provided with a valve cavity extending along the preset axis. The control valve includes a piston slidably disposed in the valve cavity. The piston divides the valve cavity into a first cavity and a second cavity. The first cavity is communicated with the cooking cavity, and the second cavity is communicated with the outside. The first transmission shaft or the second transmission shaft penetrates through the valve cavity and is fixed to the piston.

[0009] With such a setting, only when the steam oven performs steam function cooking, the transmission assembly can link the fan and the hot air blower, so that the automatic opening and closing of the fan can be realized, ensuring that the steam in the cooking cavity can be safely discharged when the door is opened, and improving the user experience.

[0010] In one embodiment, the control valve further includes an elastic member disposed in the second cavity. Two ends of the elastic member respectively abut against the piston and the end wall of the second cavity.

[0011] With such a setting, the elastic member enables the piston to reset better, avoiding the piston getting stuck in the valve cavity.

[0012] In one embodiment, the control valve further includes a deformable member disposed in the first cavity. The deformable member can absorb steam and expand.

[0013] With such a setting, the deformable member can improve the stability of the piston when sliding in the valve cavity.

[0014] In one embodiment, one of the first clutch member and the second clutch member is provided with a protrusion, and the other is provided with a groove capable of cooperating with the protrusion.

[0015] With such a setting, the cooperation between the protrusion and the groove can increase the contact area between the first clutch member and the second clutch member, thereby increasing the frictional force between the first clutch member and the second clutch member, enabling the first clutch member and the second clutch member to rotate synchronously and avoiding slippage.

[0016] In one embodiment, one end of the first transmission shaft away from the first clutch member is fixed to the fan, and the first transmission shaft and the fan can jointly slide along the preset axis. One end of the second transmission shaft away from the second clutch member is in transmission cooperation with the hot air blower.

[0017] With such a setting, the structure of the transmission assembly is simple, the number of parts is reduced, and assembly is facilitated.

[0018] In one embodiment, the transmission assembly further includes a first transmission wheel, a second transmission wheel and a synchronous belt. One of the first transmission wheel and the second transmission wheel is fixed to the motor shaft of the hot air blower, and the other is fixed to the second transmission shaft. The synchronous belt is wound around the first transmission wheel and the second transmission wheel.

[0019] With such a setting, the second transmission shaft is in transmission cooperation with the motor shaft of the hot air blower through a synchronous belt pulley group, with a simple structure and convenient assembly.

[0020] In one embodiment, the air blowing assembly further includes a wind guiding cover. The wind guiding cover is arranged on the outer top wall of the inner container and encloses the air blowing cavity with the outer top wall of the inner container.

[0021] With such a setting, the fan and the transmission assembly can be directly installed on the outer top wall of the inner container, thus facilitating the assembly of the air blowing assembly and the transmission assembly; when the fan or the transmission assembly is damaged, the wind guiding cover can also be disassembled for repairing or replacing the fan and the transmission assembly, with simple and convenient operation.

[0022] In one embodiment, the steam oven further includes an exhaust assembly arranged at the bottom of the inner container, and the exhaust assembly is communicated with the cooking cavity; and / or, the steam oven further includes a water tank arranged at the bottom of the inner container.

[0023] With such a setting, it can be avoided that the steam discharged from the exhaust assembly flows upward and condenses on the upper decorative plate and the upper cabinet panel; there is enough space at the bottom of the inner container for installing the water tank, thereby enabling the volume of the water tank to be increased, so that the water tank can hold enough water to meet the cooking requirements for a single long time, and at the same time, it can also avoid increasing the overall volume of the steam oven.

The term "and / or" used in the description of this application includes any and all combinations of one or more of the related listed items.

[0036] In the existing built-in steam oven, the oven door usually flips down to open. When the user opens the oven door during the cooking process to check the cooking status of the food, the steam in the cooking cavity will escape upward, and part of the steam will condense on the upper decorative panel of the steam oven and the upper cabinet panel above, affecting the user experience, and may also cause mildew, deformation, etc. on the upper decorative panel and the upper cabinet panel after a long time.

[0037] To solve the above problems, as Figures 1 to 5 shown, the present utility model provides a steam oven to reduce the steam escaping upward when the oven door is opened.

[0038] As Figures 1 to 3As shown in the figure, specifically, the steam oven includes an inner container 1, a hot air blower 2, a blowing component 3 and a transmission component 4, where: The inner container 1 is provided with a cooking cavity 11 and an opening 12 communicating with the cooking cavity 11; The hot air blower 2 is arranged outside the inner container 1 and is used to convey hot air to the cooking cavity 11; The blowing component 3 is arranged at the top of the inner container 1. The blowing component 3 is provided with a blowing cavity 31 and a blowing port 32 communicating with the blowing cavity 31. The orientation of the blowing port 32 is the same as that of the opening 12. The blowing component 3 includes a fan 33 rotatably arranged in the blowing cavity 31, and the fan 33 faces the blowing port 32; The transmission component 4 is arranged outside the inner container 1 and can link the hot air blower 2 and the fan 33.

[0039] In the steam oven provided by the embodiment of the present utility model, during the cooking process, the hot air blower 2 operates and conveys hot air to the cooking cavity 11 to heat the food in the cooking cavity 11; When the transmission component 4 links the hot air blower 2 and the fan 33, the fan 33 can rotate synchronously with the hot air blower 2 to form an air flow towards the blowing port 32 in the blowing cavity 31. When the user opens the oven door to observe the cooking situation of the food in the cooking cavity 11 during the cooking process, the steam in the cooking cavity 11 will escape from the opening 12, and the air flow blown out from the blowing port 32 can blow the steam escaping from the opening 12 outwards, preventing the steam from flowing upwards and condensing on the upper decorative panel and the upper cabinet panel of the steam oven, ensuring the normal use of the user, and at the same time, it can also prevent the upper decorative panel and the upper cabinet panel from getting moldy and deformed after a long time.

[0040] Moreover, the transmission component 4 links the hot air blower 2 and the fan 33, and uses the original hot air blower 2 in the steam oven to drive the fan 33 to rotate, so that additional driving elements can be saved, avoiding occupying too much space above the inner container 1 and reducing costs.

[0041] Such as Figures 3 to 4As shown, the transmission assembly 4 includes a first transmission shaft 41 and a second transmission shaft 42 that extend along a preset axis and are capable of rotating around the preset axis. One of the first transmission shaft 41 and the second transmission shaft 42 is in driving cooperation with the fan 33, and the other is in driving cooperation with the hot air blower 2. The transmission assembly 4 further includes a first clutch member 43 and a second clutch member 44 respectively disposed at the facing ends of the first transmission shaft 41 and the second transmission shaft 42. At least one of the first transmission shaft 41 and the second transmission shaft 42 can slide along the preset axis so that the first clutch member 43 contacts or separates from the second clutch member 44. The hot air blower 2 can drive the first transmission shaft 41 or the second transmission shaft 42 that is in driving cooperation with it to rotate around the preset axis. When the first transmission shaft 41 and the second transmission shaft 42 move to the position where the first clutch member 43 contacts the second clutch member 44, the first transmission shaft 41, the first clutch member 43, the second clutch member 44, and the second transmission shaft 42 can rotate synchronously around the preset axis, so that the first transmission shaft 41 or the second transmission shaft 42 that is in driving cooperation with the fan 33 can also drive the fan 33 to rotate. When the first transmission shaft 41 and the second transmission shaft 42 move to the position where the first clutch member 43 separates from the second clutch member 44, the first transmission shaft 41 or the second transmission shaft 42 that is in driving cooperation with the fan 33 does not rotate around the preset axis, so that the fan 33 does not rotate either. In this way, it is possible to control the contact or separation of the first clutch member 43 and the second clutch member 44 according to actual needs, thereby controlling whether the fan 33 rotates and avoiding the long-term operation of the fan 33 from affecting its service life.

[0042] For the sake of convenience of description, the following takes the example that the first transmission shaft 41 is in driving cooperation with the fan 33, the second transmission shaft 42 is in driving cooperation with the hot air blower 2, and the first transmission shaft 41 can slide along the preset axis closer to or away from the second transmission shaft 42 so that the first clutch member 43 contacts or separates from the second clutch member 44 for illustration.

[0043] As Figure 4 shown, in one embodiment, the hot air blower 2 is disposed on the rear wall opposite to the inner container 1 and the opening 12. The preset axis extends along the front-back direction of the steam oven, and the fan 33 rotates around the preset axis. One end of the first transmission shaft 41 away from the first clutch member 43 is fixed to the fan 33, and the first transmission shaft 41 and the fan 33 can slide together along the preset axis. One end of the second transmission shaft 42 away from the second clutch member 44 is in driving cooperation with the hot air blower 2. In this way, the structure of the transmission assembly 4 is simple, so that the number of parts can be reduced and the assembly is facilitated.

[0044] Of course, in other embodiments, the hot air blower 2 may also be disposed on the side wall, bottom wall or top wall of the inner container 1 adjacent to the opening 12. Moreover, the preset axis may also extend along the left-right direction or other directions of the steam oven, and the rotation axis of the fan 33 forms an angle with the preset axis. One end of the first transmission shaft 41 away from the first clutch 43 may be in transmission cooperation with the fan 33 through other transmission structures such as a helical gear set, a worm and worm gear set, a synchronous pulley set, etc., as long as it is ensured that the fan 33 can rotate synchronously with the first transmission shaft 41. The embodiments of the present invention do not make specific limitations herein.

[0045] As Figures 3 to 4 shown, in one embodiment, the transmission assembly 4 further includes a first transmission wheel 46, a second transmission wheel 47 and a synchronous belt 48. One of the first transmission wheel 46 and the second transmission wheel 47 is fixed to the motor shaft of the hot air blower 2, and the other is fixed to the second transmission shaft 42. The synchronous belt 48 is wound around the first transmission wheel 46 and the second transmission wheel 47. For the convenience of description, the following takes the first transmission wheel 46 being fixed to the motor shaft of the hot air blower 2 and the second transmission wheel 47 being fixed to the second transmission shaft 42 as an example for illustration. When the hot air blower 2 operates, the motor shaft of the hot air blower 2 drives the first transmission wheel 46, and the first transmission wheel 46 drives the second transmission wheel 47 to rotate synchronously through the synchronous belt 48, so as to drive the second transmission shaft 42 and the second clutch 44 to rotate synchronously. One end of the second transmission shaft 42 away from the second clutch 44 is in transmission cooperation with the motor shaft of the hot air blower 2 through a synchronous pulley set, with a simple structure and convenient assembly.

[0046] Of course, in other embodiments, one end of the second transmission shaft 42 away from the second clutch 44 may also be in transmission cooperation with the motor shaft of the hot air blower 2 through other transmission structures such as a helical gear set, a worm and worm gear set, etc., as long as it is ensured that the second transmission shaft 42 can rotate synchronously with the motor shaft of the hot air blower 2. The embodiments of the present invention do not make specific limitations herein.

[0047] As Figures 4 to 5 shown, in one embodiment, one of the first clutch 43 and the second clutch 44 is provided with a protrusion 431, and the other is provided with a groove 441 capable of cooperating with the protrusion 431. When the first clutch 43 contacts the second clutch 44, the protrusion 431 is inserted into the groove 441 to increase the contact area between the first clutch 43 and the second clutch 44, thereby increasing the friction between the first clutch 43 and the second clutch 44, so that the first clutch 43 and the second clutch 44 can rotate synchronously and prevent slipping. When the first clutch 43 is separated from the second clutch 44, the protrusion 431 disengages from the groove 441. Moreover, the first clutch 43 and the second clutch 44 may be made of wear-resistant materials to ensure the friction between the first clutch 43 and the second clutch 44 while avoiding wear of the first clutch 43 and the second clutch 44 due to long-term friction and affecting the transmission effect.

[0048] Certainly, in other embodiments, the first clutch member 43 and the second clutch member 44 may also be cooperated in other ways such as an eccentric plugging structure, a tooth meshing structure or a rough surface structure, etc., as long as it is ensured that they can rotate synchronously when they are in contact. The embodiments of the present invention do not make specific limitations here.

[0049] As Figures 4 to 5 shown, the transmission assembly 4 further includes a control valve 45. The control valve 45 is provided with a valve cavity 451 extending along a preset axis. The control valve 45 includes a piston 452 slidably disposed in the valve cavity 451. The piston 452 divides the valve cavity 451 into a first cavity 4511 and a second cavity 4512. The first cavity 4511 communicates with the cooking cavity 11, and the second cavity 4512 communicates with the outside; the first transmission shaft 41 passes through the valve cavity 451 and is fixed to the piston 452. The second cavity 4512 is close to the second transmission shaft 42 and the second clutch member 44, and the first cavity 4511 is far from the second transmission shaft 42 and the second clutch member 44. Wherein, avoiding holes with the same diameter as the diameter of the first transmission shaft 41 are opened at both ends of the control valve 45. When the first transmission shaft 41 passes through the avoiding holes, the avoiding holes can be sealed. And, the control valve 45 can be fixed on the outer top wall of the inner container 1 or the outer shell of the steam oven to support the first transmission shaft 41 and ensure the stability of the first transmission shaft 41 when sliding along the preset axis.

[0050] When the steam oven is not cooking with the steam function, the air pressure inside the cooking cavity 11 and outside the inner container 1 is the same. Therefore, the air pressure inside the first cavity 4511 and the second cavity 4512 is also the same. The piston 452 will not slide inside the valve cavity 451, and the first transmission shaft 41 will not slide along the preset axis. The first clutch member 43 and the second clutch member 44 are in a separated state. When the steam oven is cooking with the steam function, the steam generated inside the cooking cavity 11 will enter the first cavity 4511 through the pipeline 49, causing the air pressure inside the first cavity 4511 to gradually rise, while the air pressure inside the second cavity 4512 remains basically unchanged. Therefore, the piston 452 can gradually slide towards the second cavity 4512 under the action of the air pressure, thereby driving the first transmission shaft 41 and the first clutch member 43 to gradually slide along the preset axis towards the side close to the second transmission shaft 42 and the second clutch member 44 until the first clutch member 43 contacts the second clutch member 44. After cooking is completed, the steam inside the cooking cavity 11 and the first cavity 4511 gradually decreases, and the air pressure gradually drops. Therefore, the piston 452 can gradually slide towards the first cavity 4511 under the action of the air pressure, thereby driving the first transmission shaft 41 and the first clutch member 43 to slide along the preset axis towards the side away from the second transmission shaft 42 and the second clutch member 44, causing the first clutch member 43 to separate from the second clutch member 44. In this way, only when the steam oven is cooking with the steam function, the first clutch member 43 will contact the second clutch member 44, and the transmission assembly 4 can link the fan 33 with the hot air blower 2, thereby enabling the automatic opening and closing of the fan 33, ensuring that the steam inside the cooking cavity 11 can be safely discharged when the oven door is opened, and improving the user experience.

[0051] It can be understood that when the second transmission shaft 42 can slide along the preset axis, the second transmission shaft 42 passes through the valve cavity 451 and is fixed to the piston 452, and the second cavity 4512 is close to the first transmission shaft 41 and the first clutch member 43, while the first cavity 4511 is far from the first transmission shaft 41 and the first clutch member 43. When both the first transmission shaft 41 and the second transmission shaft 42 can slide along the preset axis, the number of control valves 45 is two, and they are respectively arranged corresponding to the first transmission shaft 41 and the second transmission shaft 42. The first transmission shaft 41 and the second transmission shaft 42 respectively pass through the corresponding valve cavity 451 and are fixed to the corresponding piston 452.

[0052] As Figures 4 to 5 shown, the transmission assembly 4 further includes a pipeline 49. Both ends of the pipeline 49 are respectively communicated with the first cavity 4511 and the cooking cavity 11, so that the first cavity 4511 is communicated with the cooking cavity 11. A through hole can be opened on the end wall or side wall of the second cavity 4512 on the side far from the first cavity 4511, so that the second cavity 4512 is communicated with the space between the outer shell of the steam oven and the inner container 1, that is, the second cavity 4512 is communicated with the outside.

[0053] As Figure 5As shown, the control valve 45 further includes an elastic member 453 disposed in the second cavity 4512. Both ends of the elastic member 453 are respectively abutted against the piston 452 and the end wall of the second cavity 4512. When not cooking, the air pressures in the first cavity 4511 and the second cavity 4512 are the same, and the elastic member 453 is in an unloaded state; when the piston 452 slides towards the second cavity 4512, the elastic member 453 is compressed and exerts an elastic force on the piston 452 towards the first cavity 4511; when the air pressure in the first cavity 4511 drops, the piston 452 can gradually slide towards the first cavity 4511 under the action of the elastic force of the elastic member 453 and the air pressure. The elastic member 453 enables the piston 452 to reset better and prevents the piston 452 from jamming in the valve cavity 451. Specifically, the elastic member 453 can be set as a spring, and the spring is sleeved on the first transmission shaft 41 to limit the deformation direction of the spring; of course, the elastic member 453 can also be set as other elastic elements such as a silica gel member or a rubber member, and the embodiments of the present utility model do not make specific limitations here.

[0054] As Figure 5 shown, the control valve 45 further includes a deformable member 454 disposed in the first cavity 4511, and the deformable member 454 can absorb steam and expand. When the steam oven cooks using the steaming function, steam is generated in the cooking cavity 11. After the steam enters the first cavity 4511 through the pipeline 49, the deformable member 454 will absorb the steam and expand, causing the piston 452 to gradually slide towards the second cavity 4512 under the thrust of the deformable member 454 and the air pressure, and the elastic member 453 is compressed; when the air pressure in the first cavity 4511 drops, the piston 452 can gradually slide towards the first cavity 4511 under the action of the elastic force of the elastic member 453 and the air pressure, and squeeze the deformable member 454, causing the deformable member to gradually contract. The deformable member 454 can improve the stability of the piston 452 when sliding in the valve cavity 451.

[0055] As Figure 2 shown, in one embodiment, the blowing assembly 3 further includes a wind guide cover 34, and the wind guide cover 34 is disposed on the outer top wall of the inner container 1 and encloses a blowing cavity 31 with the outer top wall of the inner container 1. In this way, the fan 33 and the transmission assembly 4 can be directly installed on the outer top wall of the inner container 1, so that it is convenient to assemble the blowing assembly 3 and the transmission assembly 4. And when the fan 33 or the transmission assembly 4 is damaged, the wind guide cover 34 can also be disassembled for repairing or replacing the fan 33 and the transmission assembly 4, and the operation is simple and convenient. Of course, in other embodiments, the blowing cavity 31 can also be formed independently by the wind guide cover 34 or enclosed by the wind guide cover 34 and the inner wall of the outer shell of the steam oven.

[0056] As Figures 1 to 2As shown in the figure, the steam oven further includes an exhaust component 5 disposed at the bottom of the inner container 1, and the exhaust component 5 is communicated with the cooking cavity 11. During the cooking process, the steam and hot air generated in the cooking cavity 11 can be discharged from the steam oven through the exhaust component 5. Since the exhaust component 5 is disposed at the bottom of the inner container 1, it is relative to the upper decorative panel and the upper cabinet panel far from the steam oven, so that the steam discharged from the exhaust component 5 can also be prevented from flowing upward and condensing on the upper decorative panel and the upper cabinet panel. Specifically, the exhaust component 5 is provided with an exhaust port 51, and the orientation of the exhaust port 51 is the same as that of the opening 12.

[0057] As Figure 2 shown in the figure, the steam oven further includes a water tank 6 disposed at the bottom of the inner container 1. There is usually enough space at the bottom of the inner container 1 for installing the water tank 6. Especially when the exhaust component 5 is disposed at the bottom of the inner container 1, the water tank 6 can be disposed at the rear side of the exhaust component 5, so that the volume of the water tank 6 can be increased, enabling the water tank 6 to hold enough water to meet the cooking requirements for a single long cooking time, and at the same time, the overall volume of the steam oven can also be prevented from increasing.

[0058] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
