Description

Technical Field

[0001] This application relates to the field of kitchen equipment technology, and in particular to a linked steam oven. Background Technology

[0002] Steam ovens, as a type of kitchen equipment, are widely used in steaming and cooking. Especially with the improvement of people's living standards, there are higher requirements for the performance and user experience of these appliances.

[0003] Commercially available steam ovens typically consist of a cabinet, a sealed door, a steam generator, and corresponding steam pipes. The cabinet contains at least one heating chamber. During operation, the steam generator produces high-temperature steam, which is then pressurized and transported through the steam pipes to the heating chamber. After cooking, the operator opens the sealed door to remove the food. Because the heating chamber and steam pipes are always connected, and the steam generator is constantly operating, steam can escape to the outside during food handling, resulting in significant heat loss.

[0004] To address the issues mentioned above, some steam ovens are equipped with sealing structures to block the heating chamber pipes. These sealing structures are operated before opening the sealing door to reduce steam entering the heating chamber. However, the sealing structures must be operated again to reconnect the steam pipes before the next heating cycle. This sealing structure makes the operation of the steam oven cumbersome and inefficient. Summary of the Invention

[0005] In order to reduce steam loss when the sealed door is opened and to achieve linkage between the sealed door and the sealing structure, this application provides a linkage steam oven.

[0006] The linked steam oven provided in this application adopts the following technical solution: A linkage steam oven includes a box body, a sealing door hinged to the box body, and a steam pipe disposed on the side wall of the box body. The box body has a steam communication hole on the side wall of the heating chamber that communicates with the steam pipe. The characteristic feature is that it further includes a linkage mechanism, the linkage mechanism including a sealing component disposed on the box body and used to prevent steam from entering the steam communication hole, and a driving component for driving the sealing component to move. The driving component and the sealing door are correspondingly disposed. When the sealing door rotates to close, the sealing door drives the drive assembly to move, which in turn moves the sealing assembly, allowing steam to pass through the steam communication hole; when the sealing door rotates to open, the drive assembly drives the sealing assembly to block steam from passing through the steam communication hole.

[0007] By adopting the above technical solution and utilizing the linkage mechanism, when the sealing door rotates to close, the sealing component opens and connects to the steam through the steam communication hole, allowing the steam to flow quickly into the heating chamber and improve the food heating speed; when the sealing door rotates to open, the sealing component closes and thus blocks the steam from passing through the steam communication hole. This solution simplifies operation and improves efficiency.

[0008] Optionally, a tee structure is provided outside the steam pipe. The tee structure has an input end, an output end, and a sealing end. The input end and the output end are respectively connected to the steam pipe and the steam communication hole. A sealing cover is installed on the sealing end of the tee structure. The sealing component is a sealing plug arranged inside the tee structure. The driving component passes through the sealing cover and is connected to the sealing plug. There is a sliding chamber between the input end and the sealing end for the sealing plug to slide. When the sealing plug slides to correspond to the output end, the steam pipe is isolated from the heating chamber.

[0009] By adopting the above technical solution, a three-way structure is set on the outside of the steam pipe, which is equipped with a sealing inner plug that can slide in the sliding chamber. When the sealing door is open, the sealing inner plug can slide to correspond to the output end, blocking the steam flow between the steam pipe and the heating chamber and preventing steam loss. When the sealing door is closed, the sealing inner plug moves away from the output end, allowing the steam in the steam pipe and the heating chamber to connect. The above structure realizes the linkage operation of connection and isolation between the steam pipe and the heating chamber, reducing steam loss and making the operation simple and convenient.

[0010] Optionally, a tee structure is provided outside the steam pipe. The tee structure has an input end, an output end, and a sealing end. The input end and the output end are respectively connected to the steam pipe and the steam communication hole. A sealing cap is installed on the sealing end of the tee structure. The sealing component is a sealing sliding cover arranged inside the steam pipe and corresponding to the input end. The area of ​​the sealing sliding cover is greater than or equal to the port area of ​​the input end. The driving component passes through the sealing cover and is connected to the sealing sliding cover. When the sealing sliding cover slides to cover the port of the input end, the steam pipe is isolated from the heating chamber.

[0011] By adopting the above technical solution, another form of sealing component for the three-way structure outside the steam pipe is disclosed. By using a sealing cover that is slidably installed inside the steam pipe, the steam pipe and the heating chamber can be isolated when it slides to cover the input end port, thus preventing steam from escaping to the outside when the operator takes out or puts out food.

[0012] Optionally, the steam pipe is provided with a tee structure, which has an input end, an output end, and a sealing end. The input end and the output end are respectively connected to the steam pipe and the steam communication hole. The sealing end of the tee structure is equipped with a sealing cap. The sealing component is a sealing plug arranged in the tee structure. The driving component passes through the steam pipe and is connected to the sealing plug. There is a sliding chamber between the input end and the sealing end for the sealing plug to slide. When the sealing plug slides to correspond with the output end, the steam pipe is isolated from the heating chamber.

[0013] By adopting the above technical solution, a three-way structure is set inside the steam pipe, which, together with a sealing plug that can slide in the sliding chamber, allows the sealing plug to slide to correspond with the output end when the sealing door is open, blocking the steam flow between the steam pipe and the heating chamber and preventing steam loss; when the sealing door is closed, the sealing plug moves away from the output end, and the steam in the steam pipe and the heating chamber are connected. The above structure realizes the linkage operation of connection and isolation between the steam pipe and the heating chamber, reducing steam loss, and is simple and convenient to operate.

[0014] Optionally, the steam pipe is provided with a tee structure, which has an input end, an output end, and a sealing end. The input end and the output end are respectively connected to the steam pipe and the steam communication hole. The input end is disposed on the wall of the tee structure. The sealing component is a sealing sliding cover arranged inside the steam pipe and corresponding to the input end. The area of ​​the sealing sliding cover is greater than or equal to the port area of ​​the input end. The driving component passes through the steam pipe and is connected to the sealing sliding cover. When the sealing sliding cover slides to cover the port of the input end, the steam pipe is isolated from the heating chamber.

[0015] By adopting the above technical solution, another form of sealing component in a steam pipe is disclosed. By using a sealing cover that is slidably installed in the steam pipe, the steam pipe and the heating chamber can be isolated when it slides to the input end port, so as to prevent steam from escaping to the outside when the operator takes out or puts out food.

[0016] Optionally, the steam communication hole is located inside the steam pipe, and the sealing component is a sealing slide plate that is slidably installed inside the steam pipe. When the sealing slide plate slides to correspond to the steam communication hole, the steam pipe is isolated from the heating chamber.

[0017] By adopting the above technical solution, another form of sealing component is disclosed. By using a sealing slide plate that is slidably installed on the steam pipe, the steam pipe and the heating chamber can be isolated when it slides to correspond to the steam communication hole, so as to prevent steam from escaping to the outside when the operator picks up or puts in food.

[0018] Optionally, the steam communication holes on the housing are evenly spaced along the sliding direction of the sealing slide plate. The sealing slide plate has a sealing part corresponding to each steam communication hole and a through hole provided in the adjacent sealing part. When the sealing part moves to correspond to each steam communication hole, the steam pipe is sealed and isolated from the heating chamber.

[0019] By adopting the above technical solution, another form of sealing component is disclosed. The steam communication holes of the steam chamber are evenly spaced, and the sealing plate has a sealing part and a through hole. When the sealing part corresponds to the steam communication hole, it can isolate the steam pipe and the heating chamber. With the help of the linkage mechanism, automatic control is achieved by rotating the sealing door.

[0020] Optionally, the sealing component is a vertical sliding plate that is slidably installed on the housing. The vertical sliding plate is provided with a driving slope for the driving component to abut. When the sealing door is closed, the vertical sliding plate is intersected with the steam communication hole. When the sealing door is opened, the vertical sliding plate automatically slides down and covers the steam communication hole.

[0021] By adopting the above technical solution, another form of sealing component is disclosed. When the sealing door is opened, gravity is used to make the vertical slide plate fall automatically to cover the steam connection hole, reducing steam loss and simplifying the operation process of the steam oven without additional operation.

[0022] Optionally, the sealing assembly is a sealing rotating plate rotatably mounted on the housing, and the driving assembly is provided with a linkage rod for driving the sealing rotating plate to rotate; when the sealing door is closed, the sealing rotating plate and the steam communication hole are interleaved; when the sealing door is opened, the driving assembly drives the sealing rotating plate to rotate and closes the steam communication hole.

[0023] By adopting the above technical solution, another form of sealing assembly is disclosed, which uses a linkage rod to drive the sealing rotating plate to rotate, thereby realizing the closing and opening of the steam communication hole and preventing excessive steam loss to the outside when taking food out or putting it in.

[0024] Optionally, the drive assembly includes a linkage rod and a linkage elastic element sleeved on the linkage rod. One end of the linkage rod is fixed to the sealing assembly, and the other end of the linkage rod passes through the side wall of the housing and corresponds to the sealing door. The linkage elastic element is used to drive the movement of the linkage rod to reset.

[0025] By adopting the above technical solution, and utilizing the cooperation of the linkage rod and the linkage elastic element, the sealing assembly can automatically block or connect the steam connection link as the sealing door opens and closes, without the need for additional manual operation.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the linkage mechanism, when the sealing door rotates and closes, the sealing component moves away to allow steam to flow through the steam connection hole, thus achieving effective steam delivery; 2. Through the linkage mechanism, when the sealing door is rotated open, the drive component drives the sealing component to block steam from passing through the steam communication hole, thereby reducing steam loss.

[0040] The following is in conjunction with the appendix Figure 1-12 This application will be described in further detail.

[0041] This application discloses a linkage steam oven.

[0042] Example 1, referring to Figure 1 A linkage-type steam oven includes a body 1, a sealing door 2 hinged to the body 1, and a steam pipe 3 disposed on the outer wall of the body 1. The body 1 has one or more heating chambers 11 along its height, with the sealing door 2 and the heating chamber 11 corresponding to each other. The body 1 has steam communication holes 12 on the inner side wall of the heating chamber 11. The steam communication holes 12 communicate with the steam pipe 3, allowing high-temperature steam generated by the heating system to be delivered to the heating chamber 11.

[0043] Reference Figure 2 and Figure 3 In order to achieve dynamic sealing adjustment of steam and steam connection hole 12, a linkage mechanism 4 is also provided on the housing 1. The linkage mechanism 4 includes a sealing component for blocking or connecting steam into the steam connection hole 12, and a drive component 42 for driving the sealing component to move.

[0044] In this embodiment, the steam pipe 3 and the steam connecting hole 12 are staggered in the horizontal direction. A tee structure 5 for connecting the steam pipe 3 and the steam connecting hole 12 is provided on the outer wall of the steam pipe 3. The tee structure 5 has an input end 51, an output end 52, and a sealing end 53. The input end 51 is connected to the steam pipe 3 via a pipe, and the output end 52 is connected to the steam connecting hole 12. A sealing cap 54 is provided at the sealing end 53 of the tee structure 5.

[0045] The sealing assembly is a hollow sealing plug 41 that is slidably arranged in the three-way structure 5. A sliding chamber 55 is formed between the sealing end 53 and the input end 51 for the sealing plug 41 to slide. The outer diameter of the sealing plug 41 is adapted to the inner wall of the sliding chamber 55 so that when the sealing plug 41 moves to the output end 52, it can isolate the heating chamber 11 from the steam pipe 3.

[0046] The drive assembly 42 includes a linkage rod 421 and a linkage elastic element 422 sleeved on the linkage rod 421. One end of the linkage rod 421 passes through the sealing end 53 and is fixed to the sealing inner plug 41. The other end of the linkage rod 421 passes through the opening side wall of the housing 1 and forms a front pushing part 424 for pushing the sealing door 2. The linkage elastic element 422 is a compression spring, one end of which is fixed to the sealing cover 54, and a retaining ring 4211 is fixed to the outer side wall of the linkage rod 421 for fixing the other end of the linkage elastic element 422.

[0047] The implementation principle of a linkage steam oven according to an embodiment of this application is as follows: When the sealing door 2 is in the closed state, the inner sealing plug 41 and the output end 52 are staggered. At this time, the heating chamber 11 and the steam pipe 3 are connected, and the linkage elastic element 422 is in a compressed state. When the sealing door 2 is rotated open, the linkage rod 421 moves horizontally under the reset action of the linkage elastic element 422, and at the same time drives the inner sealing plug 41 to move in the sliding chamber 55 and move to correspond to the output end 52. At this time, the heating chamber 11 and the steam pipe 3 are isolated. When the sealing door 2 is rotated closed, the linkage rod 421 moves horizontally under the pushing action of the sealing door 2, and drives the inner sealing plug 41 to move away from the output end 52. At this time, the heating chamber 11 and the steam pipe 3 are connected.

[0048] Example 2: This example is identical to Example 1 except for the structure and position of the sealing component.

[0049] Reference Figure 4 The sealing assembly is a sealing slide cover 47 disposed inside the steam pipe 3 and corresponding to the input end 51. The sealing slide cover 47 is generally flat and plate-shaped, and its area is greater than or equal to the port area of ​​the input end 51. One end of the linkage rod 421 passes through the sealing end 53 and is fixed to the sealing slide cover 47. When the sealing door 2 is opened, the linkage rod 421 is reset under the action of the linkage elastic element 422, and drives the sealing slide cover 47 to block the connection between the steam pipe 3 and the input end 51.

[0050] Example 3: Compared with Example 1, this example is identical to Example 1 except for the installation position of the T-junction structure.

[0051] Reference Figure 5The steam connection hole 12 and the steam pipe 3 are correspondingly provided. The steam pipe 3 has a through hole corresponding to the steam connection hole 12, that is, the steam connection hole 12 is located inside the steam pipe 3. The tee structure 5 is provided inside the steam pipe 3. The output end 52 of the tee structure 5 is connected to the steam connection hole 12, and the port of the input end 51 is directly connected to the steam pipe 3.

[0052] When the sealing door 2 is opened, the linkage rod 421 is reset under the action of the linkage elastic element 422, and drives the sealing inner plug 41 to block the port of the output end 52.

[0053] Example 4: Compared with Example 2, this example is identical to Example 2 except for the installation position of the T-junction structure.

[0054] Reference Figure 6 The sealing component is a sealing sliding cover 47 arranged inside the steam pipe 3 and corresponding to the input end 51. The sealing sliding cover 47 is generally flat and plate-shaped, and its area is greater than or equal to the port area of ​​the input end 51. One end of the linkage rod 421 passes through the sealing end 53 and the sealing sliding cover 47 for fixation. In this embodiment, the tee structure 5 is generally rectangular. In other embodiments, the specific shape of the tee structure 5 is not limited to a cuboid. It can also be set as a cylinder, prism, ring, or other regular or irregular shape according to the actual needs of installation space, processing technology, etc., to ensure the connection between each interface, the sliding fit of the sealing sliding cover 47, and the installation and operation space of the linkage rod 421.

[0055] The input end 51 is located on the side of the three-way structure 5 away from the sealing door 2. In other embodiments, the input end 51 can also be located on any other side of the three-way structure 5. A transmission structure is provided inside the three-way structure 5. The transmission structure is connected to the linkage rod 421 and the sealing slide cover 47 respectively. The linkage rod 421 drives the sealing slide cover 47 to open and close from other sides through the transmission structure. The transmission structure can be a pull rod structure, a wedge mechanism, a gear rack, or other structure that can change the direction of the driving force.

[0056] When the sealing door 2 is opened, the linkage rod 421 is reset under the action of the linkage elastic element 422, and drives the sealing sliding cover 47 to move, blocking the connection between the steam pipe 3 and the input end 51.

[0057] Example 5: In this example, except for the structure of the sealing component and the absence of a tee structure, the rest of the structure is consistent with Example 3.

[0058] Reference Figure 7The sealing assembly is a sealing slide plate 43 that is slidably installed inside the steam pipe 3. The steam pipe 3 has a guide rail 31 that guides the sealing slide plate 43 to slide horizontally. The structure of the linkage mechanism 4 is the same as in embodiment 1, which includes a linkage rod 421 and a linkage elastic element 422. One end of the linkage rod 421 passes through the steam pipe 3 and is fixedly connected to the sealing slide plate 43, and the other end passes through the side wall of the opening of the box 1, so that the sealing door 2 can be pushed against it.

[0059] The implementation principle of a linkage steam oven according to an embodiment of this application is as follows: When the sealing door 2 is in the closed state, the sealing slide plate 43 and the steam communication hole 12 are interlocked. At this time, the heating chamber 11 and the steam pipe 3 are connected, and the linkage elastic element 422 is in a compressed state. When the sealing door 2 is rotated open, the linkage rod 421 moves horizontally under the reset action of the linkage elastic element 422, and at the same time drives the sealing slide plate 43 to move horizontally and move to correspond to the steam communication hole 12. At this time, the heating chamber 11 is isolated from the steam pipe 3. When the sealing door 2 is rotated closed, the linkage rod 421 moves horizontally under the pushing action of the sealing door 2, and drives the sealing slide plate 43 to move away from the steam communication hole 12.

[0060] The structure of the drive assembly 42 is the same as that in Embodiment 1, which includes a linkage rod 421 and a linkage elastic element 422. One end of the linkage rod 421 passes through the steam pipe 3 and is fixedly connected to the sealing slide plate 43, and the other end passes through the side wall of the opening of the box 1 for the sealing door 2 to abut and push.

[0061] Example 6: In this example, except for the structure of the steam communication hole 12 and the structure of the sealing assembly, the rest of the structure is the same as in Example 5.

[0062] Reference Figure 8 The steam connection holes 12 are vertically arranged strip-shaped holes, evenly spaced along the horizontal direction. The sealing slide plate 43 is generally rectangular, with sealing portions 431 corresponding to the steam connection holes 12 one-to-one, and through holes 432 provided between adjacent sealing portions 431. When the sealing portions 431 correspond one-to-one with the steam connection holes 12, the heating chamber 11 is isolated from the steam pipe 3; when the sealing portions 431 and the steam connection holes 12 are staggered, the heating chamber 11 is connected to the steam pipe 3.

[0063] Compared to Embodiment 2, this embodiment reduces the required movement distance of the linkage rod 421 by cooperating with the steam communication hole 12 and the sealing part 431.

[0064] The structure of the drive assembly 42 is the same as that in Embodiment 1, which includes a linkage rod 421 and a linkage elastic element 422. One end of the linkage rod 421 passes through the steam pipe 3 and is fixedly connected to the sealing slide plate 43, and the other end passes through the side wall of the opening of the box 1 for the sealing door 2 to abut and push.

[0065] Example 7: In this example, except for the structure of the sealing component, the rest of the structure is the same as in Example 5.

[0066] Reference Figure 9 The sealing assembly is a vertical sliding plate 48 that is lifted and slidably installed on the steam pipe 3. The steam pipe 3 has a vertical guide rail 32 that guides the vertical sliding plate 48 to slide, and at the bottom of the vertical guide rail 32 there is an abutment plate 33 for the vertical sliding plate 48 to be positioned and abutted. The side wall of the vertical sliding plate 48 has a driving ramp 481 for the driving assembly 42 to push.

[0067] The structure of the linkage mechanism 4 is the same as that in Embodiment 1, which includes a linkage rod 421 and a linkage elastic element 422. One end of the linkage rod 421 passes through the steam pipe 3 and corresponds to the driving inclined surface 481 of the vertical slide plate 48, and the other end passes through the side wall of the opening of the box 1 for the sealing door 2 to abut and push.

[0068] When the sealing door 2 is closed, the linkage rod 421 is located at the bottom of the driving slope 481, and the vertical slide plate 48 is intersected with the steam connection hole 12. At this time, the heating chamber 11 is connected to the steam pipe 3, and the linkage elastic element 422 is in a compressed state. When the sealing door 2 is rotated open, the linkage rod 421 moves horizontally under the reset action of the linkage elastic element 422. The linkage rod 421 moves away from the vertical slide plate 48 along the driving slope 481, and the vertical slide plate 48 automatically falls to the abutment plate 33 under the action of gravity and covers the steam connection hole 12. When the sealing door 2 is rotated closed, the linkage rod 421 moves horizontally under the pushing action of the sealing door 2. Under the action of the driving slope 481, the vertical slide plate 48 is driven to move vertically upward, so that the steam connection hole 12 is connected to the steam pipe 3.

[0069] Example 8: In this example, except for the structure of the sealing component, the rest of the structure is the same as in Example 7.

[0070] Reference Figure 10 The sealing assembly is a sealing rotating plate 44 rotatably mounted on the housing 1. The sealing rotating plate 44 has a rotating shaft 45 that rotates with the housing 1. A linkage gear 451 is fixed on the rotating shaft 45 of the sealing rotating plate 44. The linkage gear 451 is arranged coaxially with the rotating shaft 45.

[0071] The drive assembly 42 includes a linkage rod 421 slidably mounted on the housing 1 and a linkage elastic element 422 that drives the linkage rod 421 to reset. One end of the linkage rod 421 passes through the steam pipe 3, and the other end passes through the open side wall of the housing 1. The linkage rod 421 has a linkage tooth surface 423 in the area inside the steam pipe 3 that meshes with the linkage gear 451. When the sealing door 2 is closed, the sealing slide plate 43 intersects with the steam communication hole 12. At this time, the heating chamber 11 is connected to the steam pipe 3, and the linkage elastic element 422 is in a compressed state.

[0072] Example 9: In this example, except for the structure of the sealing component, the rest of the structure is the same as in Example 8.

[0073] Reference Figure 11 The sealing assembly is a sealing rotating plate 44 rotatably mounted on the housing 1. The sealing rotating plate 44 has a rotating shaft 45 that rotatably engages with the housing 1. A linkage cam 452 is fixed on the rotating shaft 45 of the sealing rotating plate 44, and the linkage cam 452 and the rotating shaft 45 are arranged coaxially. A rotating torsion spring 453 is also wound around the rotating shaft 45 of the sealing rotating plate 44. One end of the rotating torsion spring 453 is limited and arranged on the sealing rotating plate 44, and the other end is limited and arranged on the outer wall of the housing 1.

[0074] The drive assembly 42 includes a linkage rod 421 slidably mounted on the housing 1 and a linkage elastic element 422 for resetting the linkage rod 421. One end of the linkage rod 421 passes through the steam pipe 3, and the other end passes through the open side wall of the housing 1. The linkage rod 421 has a rear pusher 426 at the end of the steam pipe 3 for pushing the linkage cam 452.

[0075] When the sealing door 2 is closed, the rear push part 426 of the linkage rod 421 abuts against the linkage cam 452, causing the sealing slide plate 43 to intersect with the steam communication hole 12, and the rotating torsion spring 453 is in a rotating compression state, which has the tendency to drive the sealing rotating plate 44 to rotate. At this time, the heating chamber 11 and the steam pipe 3 are connected, and the linkage elastic element 422 is in a compressed state.

[0076] Example 10: Compared with Example 1, this embodiment is identical in all aspects except for the structure of the sealing component and the linkage mechanism.

[0077] Reference Figure 12 The sealing assembly is a solenoid valve body 46 disposed in the steam communication hole 12, with both ends of the solenoid valve body 46 connected to the steam pipe 3 and the heating chamber 11, respectively. The drive assembly 42 includes a control element 425 for controlling the opening and closing of the solenoid valve body 46 and a linkage elastic element 422 for resetting the drive control element 425.

[0078] The solenoid valve body 46 is a normally closed solenoid valve. The control element 425 is slidably mounted on the housing 1 and is used to control the energization of the solenoid valve body 46. When the sealing door 2 is opened, the end of the control element 425 is provided with a conductive insert 4251. The solenoid valve body 46 has a slot 461 for inserting the conductive insert 4251. When the conductive insert 4251 is inserted into the slot 461, the solenoid valve body 46 is energized and switches to the connected state. When the conductive insert 4251 is disengaged from the slot 461, the solenoid valve body 46 is de-energized and switches to the closed state.

[0079] In other embodiments, the drive source of the drive assembly 42 can also be pushed directly without the aid of the sealing door 2.
