Abstract
Description
Technical Field
[0001] This application relates to the field of kitchen appliances technology, and in particular to a steam oven. Background Technology
[0002] Steam ovens typically consist of an inner cavity, a baking tray, and a heating element, which is usually located at the top of the inner cavity to ensure even heating of food. Before cooking, the user must first open the oven door, then pull out the baking tray, place the food on it, push the tray back into the inner cavity, and finally close the door. Each cooking session requires manually pushing and pulling the tray and manually opening and closing the door, which is cumbersome. While some steam ovens are designed with automatic baking tray or door movement, these mechanisms can become stuck and immobile in the event of a power outage, causing further inconvenience to the user. Summary of the Invention
[0003] Therefore, it is necessary to provide a steam oven that, while enabling automatic pushing and pulling of the baking tray and automatic opening and closing of the door, can also be manually operated in the event of a power outage, thereby improving the user experience.
[0004] The steam oven includes an inner cavity assembly, a baking tray assembly, a door, a drive mechanism, and a transmission mechanism. The inner cavity assembly includes an inner cavity with a cooking cavity, an opening, and a clearance opening. The opening and the clearance opening are respectively connected to the cooking cavity. The opening is used for food to enter and exit, and the clearance opening is located at the top or bottom of the inner cavity and extends along the depth direction of the inner cavity. The baking tray assembly is located in the cooking cavity and is slidably connected to the inner cavity assembly along the depth direction of the inner cavity. The door is located at the opening and is rotatably connected to the bottom of the inner cavity. The drive mechanism includes a drive component, an electromagnetic clutch, and a transmission assembly. The electromagnetic clutch is drively connected between the drive component and the transmission assembly. The transmission assembly is connected to the baking tray assembly through the clearance opening. The transmission mechanism drively connects the baking tray assembly and the door and is used to drive the baking tray assembly and the door to move synchronously. When the electromagnetic clutch is de-energized, the baking tray assembly and the door can be manually driven.
[0005] Understandably, in the drive mechanism, the drive component provides the power for the movement of the baking tray assembly and the door. The electromagnetic clutch and transmission assembly transmit power from the drive component to the baking tray assembly. The baking tray assembly and the door achieve synchronized movement through the transmission mechanism. This allows the door to automatically rotate and open when the baking tray is automatically removed from the inner pot, and to automatically rotate and close when the baking tray is automatically moved into the inner pot, simplifying the user's operation. The power transmission can be controlled by controlling the on / off state of the electromagnetic clutch circuit. When the electromagnetic clutch is energized, power can be transmitted from the drive component to the transmission assembly to achieve automatic movement of the baking tray assembly and the door. When the electromagnetic clutch is de-energized, it cannot transmit power from the drive component to the transmission assembly. In this case, the baking tray assembly and the door can be manually moved by the user to prevent them from jamming due to power failure.
[0006] In one embodiment, the steam oven further includes a heating element disposed within the cooking cavity, the heating element being slidably connected to the top of the inner cavity; The baking pan assembly includes a baking pan, and the projection of the heating element along the height direction of the inner liner at least covers the bottom of the baking pan; The clearance opening is located at the top of the inner liner. The transmission assembly is connected to the heating element through the clearance opening. The transmission mechanism drives the heating element and the baking pan assembly to drive the heating element and the baking pan assembly to slide synchronously along the depth direction of the inner liner.
[0007] In one embodiment, the transmission assembly includes a transmission rack and a transmission gear that mesh with each other, the transmission gear being driven by the electromagnetic clutch, and the transmission rack passing through the clearance opening and connected to the heating element.
[0008] In one embodiment, one of the heating element and the inner liner is provided with a first sliding groove extending along the depth direction of the inner liner, and the other is provided with a first sliding part, the first sliding part being slidably connected to the groove wall of the first sliding groove.
[0009] In one embodiment, the transmission mechanism includes a linkage arm connected between the heating element and the baking pan assembly, and close to the side wall of the inner liner; Along the first direction, the linkage arm is provided on at least one side of the baking pan, and along the depth direction of the inner liner, the linkage arm is provided on the side of the baking pan away from the opening; The first direction, the inner liner depth direction, and the inner liner height direction are all set at angles to each other.
[0010] In one embodiment, the inner pot assembly includes a support frame mounted on the side wall of the inner pot, the support frame being slidably connected to the baking pan assembly.
[0011] In one embodiment, one of the baking pan assembly and the support frame is provided with a first slide rail extending along the depth direction of the inner pot, and the other is provided with a second sliding part, which is slidably connected to the first slide rail.
[0012] In one embodiment, the baking pan assembly further includes a support for supporting the baking pan; the support is slidably connected to the support frame and connected to the heating element.
[0013] In one embodiment, the transmission mechanism further includes a linkage assembly, which includes a first linkage and a second linkage rotatably connected to the first linkage. The end of the first linkage away from the second linkage is connected to the support member. The baking tray assembly is angled relative to the first linkage. The end of the second linkage away from the first linkage is slidably connected to the door body.
[0014] In one embodiment, a sliding seat is connected to the side of the door facing the cooking cavity. The sliding seat is angled to the door and has a second sliding groove. The second connecting rod passes through the second sliding groove and is slidably connected to the groove wall of the second sliding groove. Attached Figure Description

The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.
[0023] Please see Figures 1 to 6 This application provides a steam oven 100, which includes an inner cavity assembly 10, the inner cavity assembly 10 including an inner cavity 11, the inner cavity 11 having a cooking cavity 101 and an opening 102 communicating with the cooking cavity 101, and food entering and exiting the cooking cavity 101 through the opening 102.
[0024] like Figure 1 , Figure 5 and Figure 6 As shown, in an optional embodiment, the steam oven 100 further includes a baking tray assembly 20 and a door 30. The baking tray assembly 20 is disposed within the cooking cavity 101 and is slidably connected to the inner liner assembly 10 along the depth direction of the inner liner 11, facilitating pushing in and out relative to the inner liner 11. The door 30 is disposed at the opening 102 and is rotatably connected to the bottom of the inner liner 11, allowing for opening and closing relative to the opening 102 by rotating the door 30, making operation simple.
[0025] like Figures 1 to 6 As shown, in an optional embodiment, the steam oven 100 further includes a drive mechanism 40 and a transmission mechanism 50. The drive mechanism 40 provides power for the movement of the baking tray assembly 20, and the transmission mechanism 50 drives the baking tray assembly 20 and the door 30, causing them to move synchronously. Thus, the baking tray assembly 20 and the door 30 can move automatically and synchronously, eliminating the need for the user to manually push or pull the baking tray and manually open or close the door 30, freeing the user's hands, making operation simpler, and saving the user effort.
[0026] In a specific embodiment, the baking tray assembly 20 includes a baking tray for holding food.
[0027] In related technologies, before cooking, the user needs to open the oven door, pull out the baking tray, place the food on the tray, push the tray back into the inner cavity, and finally close the door—a five-step process. Even with automatic door opening mechanisms, the user still needs to manually pull out the baking tray, place the food, push the tray back in, and manually close the door—four steps in total. Automatic door opening / closing or automatic baking tray pushing / pulling mechanisms in related technologies also require three steps. This application, however, only requires the user to issue an electrical signal to the oven 100. The baking tray assembly 20 will automatically extend, and the door 30 will rotate synchronously to open relative to the inner cavity 11. The user then places the food in the oven. After placing the food, the baking tray assembly 20 automatically moves back into the inner cavity 11, and the door 30 rotates synchronously to close relative to the inner cavity 11, preventing the user from forgetting to close the door. The entire process is simplified to just one step: placing the food, greatly reducing manual operation for the user. Especially in the cooking process of some recipes, it is necessary to open the door 30 multiple times to push out the baking tray to add ingredients. Manually opening and closing the door and manually pushing and pulling the baking tray assembly 20 multiple times is quite cumbersome. However, the above-mentioned settings of this application realize the automatic opening and closing of the door and the automatic movement of the baking tray assembly 20, which greatly improves the user experience.
[0028] Meanwhile, after the food is cooked, the baking tray assembly 20 automatically extends and the door 30 automatically opens. Users do not need to face the overheated steam due to manual operation. Users can automatically retreat to a safe distance to prevent burns. Users also do not need to wait for the steam oven 100 to cool down before manually opening the steam oven 100 to take out the food, saving users time.
[0029] like Figure 3 and Figure 4As shown, in a specific embodiment, the inner pot 11 is provided with a clearance opening 103 communicating with the cooking cavity 101. The clearance opening 103 is located at the top or bottom of the inner pot 11 and extends along the depth direction of the inner pot 11. The drive mechanism 40 includes a drive component 41, an electromagnetic clutch 42, and a transmission assembly 43. The electromagnetic clutch 42 is drively connected between the drive component 41 and the transmission assembly 43. The transmission assembly 43 is connected to the baking pan assembly 20 through the clearance opening 103. Thus, the drive component 41 can provide a power source, the electromagnetic clutch 42 can transmit the power of the drive component 41 to the transmission assembly 43, and the transmission assembly 43 controls the movement of the baking pan assembly 20. The electromagnetic clutch 42 can be independently controlled to be energized and de-energized, thereby controlling the driving state of the baking pan assembly 20 and the door 30. When the electromagnetic clutch 42 is energized, it can transmit power normally. When the electromagnetic clutch 42 is de-energized, it cannot transmit the power of the drive component 41 to the transmission component 43. At this time, the baking tray assembly 20 and the door 30 can be manually driven so that the baking tray assembly 20 can be manually pushed and the door 30 can be manually opened and closed when the power is off. This prevents the baking tray assembly 20 and the door 30 from getting stuck and hindering the user, thus improving the user experience.
[0030] In a specific embodiment, the steam oven 100 includes a control board and a user panel. The user panel, the drive unit 41, and the electromagnetic clutch 42 are electrically connected to the control board. The control board can control the power supply of the drive unit 41 and the electromagnetic clutch 42 according to the instructions input by the user panel, so as to switch between automatic and manual operation of the baking tray assembly 20 and the door 30 according to user needs, thereby improving the user experience.
[0031] In this application, the first direction, the depth direction of the inner liner 11, and the height direction of the inner liner 11 are arranged at angles to each other. For ease of explanation, the first direction, the depth direction of the inner liner 11, and the height direction of the inner liner 11 are arranged perpendicularly to each other, with the first direction as the x-axis, the depth direction of the inner liner 11 as the y-axis, and the height direction of the inner liner 11 as the z-axis.
[0032] like Figure 1 , Figure 2 and Figure 3 As shown, in an optional embodiment, the steam oven 100 further includes a heating element 60 disposed in the cooking cavity 101. The heating element 60 is disposed at the top of the inner liner 11, and the projection of the heating element 60 along the height direction of the inner liner 11 at least covers the bottom of the baking pan. With this arrangement, the heat emitted by the heating element 60 can be evenly radiated downwards to the baking pan and cover the food on the baking pan, which helps to promote the even heating of the food and ensure the cooking effect of the food.
[0033] like Figure 1 , Figure 3 and Figure 4As shown, in a specific embodiment, the heating element 60 is slidably connected to the top of the inner pot 11, and the clearance opening 103 is located at the top of the inner pot 11. The transmission assembly 43 is connected to the heating element 60 through the clearance opening 103, and the transmission mechanism 50 drives the heating element 60 and the baking tray assembly 20 to slide synchronously along the depth direction of the inner pot 11. Thus, the transmission assembly 43 first transmits power to the heating element 60, and then the transmission mechanism 50 causes the heating element 60 and the baking tray assembly 20 to move synchronously. This arrangement ensures that the projection of the heating element 60 along the height direction of the inner pot 11 always covers at least the bottom of the baking tray, ensuring that the heating element 60 always maintains a corresponding position to the baking tray before and after the baking tray enters and exits the inner pot 11. After the food is placed on the baking tray, the baking tray assembly 20 and the heating element 60 move synchronously into the inner pot 11. This process requires no user operation, and the heating element 60 can then begin heating the baking tray, saving heating time. After cooking, the baking pan and heating element 60 can be simultaneously removed from the inner pot 11. At this time, the residual heat of the heating element 60 can still be dissipated into the baking pan, reducing the cooling rate of the food in the baking pan. Especially in winter, this can prolong the time that the food stays warm, which helps to maintain the freshness of the food. In addition, compared with the prior art, which requires manually reaching deep into the inner pot 11 to clean the heating element 60, which is very inconvenient, the heating element 60 in this application can be extended out of the inner pot 11 along with the baking pan, making the cleaning of the heating element 60 much simpler.
[0034] like Figure 3 and Figure 4 As shown, in a specific embodiment, the transmission assembly 43 includes a transmission rack 431 and a transmission gear 432 that mesh with each other. The transmission gear 432 is connected to the electromagnetic clutch 42, and the transmission rack 431 passes through the clearance opening 103 and is connected to the heating element 60. Thus, the electromagnetic clutch 42 transmits the power of the driving element 41 to the transmission gear 432, causing the transmission gear 432 to rotate, thereby driving the transmission rack 431 to move along the extension direction of the clearance opening 103, and thus causing the heating element 60 to slide automatically relative to the inner liner 11. Power can be transmitted between the transmission rack 431 and the transmission gear 432, and they always maintain meshed rotation. That is, power can be transmitted from the transmission rack 431 to the transmission gear 432, and vice versa. Therefore, when the electromagnetic clutch 42 is de-energized, the baking pan assembly 20 can be manually pushed, thereby moving the heating element 60 and the transmission rack 431 connected to the heating element 60. Because the electromagnetic clutch 42 is de-energized, the power transmitted from the transmission rack 431 to the transmission gear 432 will not affect the drive element 41 through the electromagnetic clutch 42. In a specific embodiment, the drive element 41 is a motor, etc.
[0035] like Figure 3 and Figure 4As shown, in a specific embodiment, one of the heating element 60 and the inner liner 11 is provided with a first sliding groove 611 extending along the depth direction of the inner liner 11, and the other is provided with a first sliding part 104, which is slidably connected to the groove wall of the first sliding groove 611. Thus, by providing the first sliding groove 611 and the first sliding part 104, a guiding effect is achieved on the movement of the heating element 60 relative to the inner liner 11, promoting the smooth movement of the heating element 60 along the depth direction of the inner liner 11.
[0036] In one specific embodiment, a first sliding groove 611 is provided on the inner liner 11, and a first sliding part 104 is provided on the heating element 60. Both the first sliding groove 611 and the first sliding part 104 gradually narrow from the top of the inner liner 11 toward the baking pan along the height direction of the inner liner 11. The groove wall of the first sliding groove 611 and the surface of the first sliding part 104 abut against each other. The first sliding groove 611 forms an inclined side wall to limit the first sliding part 104 along the height direction, so that the heating element 60 will not fall downward.
[0037] like Figure 3 and Figure 4 As shown, in another specific embodiment, a first sliding groove 611 is provided on the heating element 60, and a first sliding part 104 is provided on the inner liner 11. Both the first sliding groove 611 and the first sliding part 104 gradually expand from the top of the inner liner 11 toward the baking pan along the height direction of the inner liner 11. The groove wall of the first sliding groove 611 abuts against the surface of the first sliding part 104. The first sliding groove 611 forms an inclined side wall to limit the first sliding part 104 along the height direction, so that the heating element 60 will not fall downwards.
[0038] like Figure 4 As shown, in a specific embodiment, the heating element 60 includes a heating plate 61 and a heating tube 62. The heating tube 62 is installed inside the heating plate 61, and the heating plate 61 is slidably connected to the inner liner 11. The arrangement of the heating plate 61 facilitates the even outward dissipation of heat from the heating tube 62, and also helps protect the heating tube 62, reducing potential collisions during use. Furthermore, the flat surface of the heating plate 61 makes cleaning easier, reducing the formation of dirt-prone areas, improving cleaning speed, and enhancing the user experience.
[0039] In a specific embodiment, the heating tube 62 is arranged to reciprocate along the first direction or along the depth direction of the inner liner 11, which facilitates the arrangement of a longer heating tube 62 and improves the heating efficiency.
[0040] like Figure 5 and Figure 6As shown, in a specific embodiment, the transmission mechanism 50 includes a linkage arm 51, which connects the heating element 60 and the baking pan assembly 20 and is located near the side wall of the inner liner 11. Along the first direction, at least one side of the baking pan has the linkage arm 51, thus transmitting power from the heating element 60 to the baking pan assembly 20 via the linkage arm 51, thereby causing the baking pan assembly 20 to move synchronously with the heating element 60. Furthermore, along the depth direction of the inner liner 11, the side of the baking pan furthest from the opening 102 has the linkage arm 51 to reduce interference and improve aesthetics.
[0041] like Figure 5 and Figure 6 As shown, in a specific embodiment, the linkage arm 51 includes a first arm body 511 and a second arm body 512. The first arm body 511 is connected to the second arm body 512. The first arm body 511 extends along the depth direction of the inner liner 11 and is connected to the heating element 60. The second arm body 512 extends along the height direction of the inner liner 11 and is connected to the baking tray assembly 20, thereby realizing the connection between the heating element 60 and the baking tray assembly 20, which is conducive to the stable transmission of force, and thus stably drives the synchronous movement of the baking tray assembly 20 and the heating element 60.
[0042] like Figure 5 and Figure 6 As shown, in a specific embodiment, the inner pot assembly 10 includes a support frame 12 installed on the side wall of the inner pot 11. The support frame 12 is slidably connected to the baking pan assembly 20. The support frame 12 provides support for the sliding of the baking pan assembly 20, thereby reducing the impact on the inner wall of the inner pot 11.
[0043] like Figure 5 and Figure 6 As shown, in a specific embodiment, one of the baking pan assembly 20 and the support frame 12 is provided with a first slide rail 121 extending along the depth direction of the inner pot 11, and the other is provided with a second sliding part 211, which is slidably connected to the first slide rail 121. Thus, through the cooperation of the first slide rail 121 and the second sliding part 211, a guiding effect is achieved on the movement of the baking pan assembly 20 relative to the inner pot 11, promoting smooth movement of the baking pan assembly 20 along the depth direction of the inner pot 11. For example, the first slide rail 121 is provided on the baking pan assembly 20, and the second sliding part 211 is provided on the support frame 12; or, the first slide rail 121 is provided on the support frame 12, and the second sliding part 211 is provided on the baking pan assembly 20.
[0044] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, in a specific embodiment, the baking tray assembly 20 further includes a support member 21 for supporting the baking tray, facilitating its removal. The support member 21 is slidably connected to the support frame 12 and to the heating element 60. Specifically, the support member 21 is connected to the linkage arm 51. The support member 21 serves both a supporting and sliding connection function, enabling the baking tray to move synchronously without requiring modifications to the baking tray, thus reducing production costs. For example, the first slide rail 121 is provided on the side of the support member 21 facing away from the baking tray.
[0045] In a specific embodiment, the steam oven 100 also includes a gravity sensor, which is located on the support member 21 or the support frame 12, avoiding the structure at the sliding connection between the support member 21 and the support frame 12 to prevent interference. The gravity sensor is used to detect the weight change borne by the support member 21 or the support frame 12, thereby determining whether food has been placed or added to the baking tray, and feeding back the weight increase signal to the control board, which then controls the drive mechanism 40 to drive the baking tray and the door 30 to move synchronously and automatically, so that after food is placed on the baking tray, the baking tray automatically moves into the inner cavity 11 and the door 30 automatically closes.
[0046] like Figure 1 and Figure 2 As shown, in an optional embodiment, the transmission mechanism 50 further includes a linkage assembly 52, which is connected to the baking pan assembly 20 and slidably connected to the door body 30. Thus, the baking pan assembly 20 transmits power to the door body 30 via the linkage assembly 52, making operation simple.
[0047] like Figure 2 As shown, in a specific embodiment, the linkage assembly 52 includes a first linkage 521 and a second linkage 522 rotatably connected to the first linkage 521. The end of the first linkage 521 away from the second linkage 522 is connected to the baking tray assembly 20, and the baking tray assembly 20 is angled relative to the first linkage 521. The end of the second linkage 522 away from the first linkage 521 is slidably connected to the door body 30. Thus, the first linkage 521 transmits the power of movement of the baking tray assembly 20 to the second linkage 522, which then transmits the power to the door body 30. The second linkage 522 is rotatably connected to the first linkage 521 and slidably connected to the door body 30, adapting to the rotation of the door body 30 while transmitting power.
[0048] In a specific embodiment, the support member 21 is connected to the first connecting rod 521. While the support member 21 slides relative to the support frame 12, it also drives the door body 30 to rotate through the connecting rod assembly 52.
[0049] like Figure 1 and Figure 2As shown, in a specific embodiment, a sliding seat 70 is connected to the side of the door 30 facing the cooking cavity 101. The sliding seat 70 is set at an angle to the door 30, and the sliding seat 70 is provided with a second sliding groove 71. The second connecting rod 522 passes through the second sliding groove 71 and is slidably connected to the groove wall of the second sliding groove 71. The second sliding groove 71 is provided to accommodate the movement of the second connecting rod 522 when the door 30 rotates, so as to promote the smooth rotation of the door 30.
[0050] like Figure 1 and Figure 2 As shown, in a specific embodiment, the first connecting rod 521 extends along the height direction of the inner liner 11. The second sliding groove 71 includes a first groove segment 711 and a second groove segment 712 connected to the first groove segment 711. The first groove segment 711 extends along the height direction of the door body 30, and the first groove segment 711 and the second groove segment 712 are set at an obtuse angle. The second groove segment 712 extends from the first groove segment 711 toward the cooking cavity 101. The first connecting rod 521 moves along the second connecting rod 522 in the first groove segment 711 and the second groove segment 712 to accommodate the rotation of the door body 30. When the door 30 is closed, the second link 522 is located at the junction of the first groove segment 711 and the second groove segment 712. As the door 30 gradually opens outward, with the outward movement of the baking tray assembly 20, the first link 521 exerts a force on the second link 522 towards the outside of the inner liner 11. The rotation of the door 30 causes the groove wall of the second sliding groove 71 to exert a resisting force on the second link 522 away from the cooking cavity 101, pushing the second link 522 away from the second groove segment 711. As the door 30 rotates in the direction of 12, the second link 522 slides within the second sliding groove 71 while rotating relative to the first link 521. The angle between the second link 522 and the first link 521 gradually decreases. As the door 30 continues to rotate, the second link 522 moves from the first groove segment 711 to the second groove segment 712. The angle between the second link 522 and the first link 521 gradually increases. When the door 30 is fully open, the angle between the second link 522 and the first link 521 reaches its maximum.
[0051] In a specific embodiment, the connection between the first groove segment 711 and the second groove segment 712 is provided with a smooth transition to avoid the second connecting rod 522 from getting stuck.
[0052] In a specific embodiment, the steam oven 100 can be controlled by a voice module, which is equipped with a voice receiving module and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the control board controls the steam oven 100 to perform corresponding operations, thereby realizing intelligent control of the steam oven 100 and improving the user experience.
