Description

Technical Field

[0001] This utility model relates to the field of kitchenware technology, and in particular to a layered oven. Background Technology

[0002] An oven generates heat through heating elements, using methods such as heat radiation, heat conduction, or hot air convection to heat food until cooked or achieve a specific baking effect. Layer ovens typically have their interiors divided into two or more independent baking layers, allowing users to bake food on different layers simultaneously.

[0003] Currently, most layer ovens consist of stacked individual ovens or a single oven cavity with multiple heating layers. However, layer ovens composed of multiple stacked oven units occupy a large space and require multiple power cords, each unit needing its own power cord, increasing the complexity of installation and use. Layer ovens with a single oven cavity and multiple heating layers cannot individually control the temperature and time of each heating layer, resulting in poor flexibility. Furthermore, if the oven malfunctions, the entire oven may need to be repaired or replaced, leading to high repair costs. Utility Model Content

[0044] This utility model proposes a layered oven, such as Figure 1 and Figure 2 As shown, it includes:

[0045] The enclosure 100 has a power bus;

[0046] At least two baking trays 200 are detachably stacked and installed inside the housing 100. Each baking tray 200 forms a baking chamber for placing food for baking. Each baking tray 200 has a power input terminal that is electrically connected to a power bus.

[0047] More specifically, tiered ovens are typically composed of stacked individual ovens or a single oven cavity with multiple heating layers. Because each oven unit is independent, they usually have their own shell and structural support, resulting in a significant increase in the overall vertical height of the oven and thus occupying more space. Each oven unit requires a separate power cord, which not only increases the number of wires but can also lead to complex and messy wiring management. Furthermore, the use of multiple power outlets may increase safety hazards. Installing multiple independent oven units requires precise alignment and securing to ensure their stability and safety. Simultaneously, users need to control each oven unit individually, increasing operational complexity and time costs.

[0048] Layered ovens, consisting of a single oven cavity and multiple heating layers, offer limited flexibility and versatility. Because the entire cavity is a single unit and the heating layers are typically fixed within it, users cannot individually control the temperature and time of each layer. This is especially problematic when baking multiple different ingredients or performing various cooking tasks simultaneously. If the oven malfunctions, the integrated heating layers and cavity may require repair or replacement of the entire oven. This not only increases repair costs but can also render the oven unusable for extended periods, impacting the user's cooking plans and efficiency. Furthermore, because the heating layers cannot be independently controlled, the entire oven cavity still needs to be heated to the set temperature when only a portion of the oven space is used. This not only wastes energy but can also lead to unnecessary heat loss and extended cooking times.

[0049] In conclusion, both of these common layer oven designs have their own problems and require structural improvements and optimizations to increase space utilization efficiency, reduce installation and usage complexity, enhance flexibility, and lower maintenance costs.

[0050] Therefore, this application proposes a layered oven, including a housing 100 with a power bus and at least two baking trays 200 detachably stacked within the housing 100. Each baking tray 200 forms a baking chamber for placing food for baking, wherein the power input terminal of the baking tray 200 is electrically connected to the power bus of the housing 100. Each baking tray 200 is an independent baking unit with a complete structure and function. Each has its own independent heating element (such as a heating wire, heating tube, etc.) and temperature control system, allowing for independent baking operations. This design allows users to set different baking parameters (such as temperature, time, etc.) in each baking tray as needed to achieve diverse baking effects. Since the baking tray 200, as an independent baking unit, does not need to share components with other baking units, the heating state of one baking tray 200 will not affect the other baking trays 200.

[0051] In essence, compared to traditional layered ovens composed of multiple independent oven units stacked together, the baking box 200 of this application does not have a separate outer frame. This means that the baking boxes 200 do not have independent, separating outer frames, allowing them to fit together more tightly, reducing space waste and improving the overall compactness and space utilization of the oven. Simultaneously, the entire box body 100 serves as the external support structure of the layered oven, bearing the heat and pressure generated during baking and preventing deformation or damage. Specifically, the frame 230 includes a top plate 110, a bottom plate 120, and a frame 230 for mounting the control panel 150. This is equivalent to replacing the outer frame of an independent oven unit with the entire outer frame 230 of the layered oven, thus achieving more compact and efficient space utilization.

[0052] Meanwhile, traditional stacked ovens, composed of individual ovens, do not have special power supply solutions for ease of disassembly and installation; each oven unit has its own power supply line. This necessitates a separate power line for each individual oven unit, resulting in complex power supply wiring for the entire oven system and increasing the difficulty of wiring management. Therefore, this application adopts a modular design to simplify the power supply wiring. Each baking tray 200 is electrically connected to the power bus of the cabinet 100 via its own power input terminal, thus achieving power supply functionality. The entire stacked oven has only one power bus. When a baking tray 200 needs to be disassembled, simply disconnect its power input terminal from the power bus; the operation is simple and quick. Similarly, during reinstallation, simply reconnect the power input terminal to the power bus; no complex wiring layout or connection work is required.

[0053] In one embodiment of this application, the layer oven includes a housing 100 and three baking trays 200. The arrangement of the three baking trays 200 not only meets the needs of large-scale baking but also ensures the flexibility and versatility of the baking process. Users can choose to bake multiple foods simultaneously or set different baking parameters in different baking trays 200 according to actual needs to achieve diverse baking effects.

[0054] This utility model includes a housing 100 and at least two baking trays 200. The baking trays 200 are detachably stacked and installed inside the housing 100, and each baking tray 200 has a power input terminal electrically connected to the power bus of the housing 100. Compared with traditional layer ovens, the housing 100 of this application is located on the outside of the entire layer oven, and the baking trays 200 are interconnected, making the entire layer oven more compact and improving space utilization. The power input terminal of each baking tray 200 is electrically connected to the power bus of the housing 100, simplifying the installation and use process. At the same time, the baking trays 200 of this application can be independently controlled, providing high overall flexibility, and each baking tray 200 can be individually repaired or replaced, reducing maintenance costs.

[0055] In one embodiment, such as Figure 2 As shown, the layered oven also includes:

[0056] The power cord 300 has multiple terminals 310 that are matched with the power input terminals of the baking tray 200. One end of the power cord 300 is connected to the power bus. This connection of one end of the power cord 300 to the power bus enables centralized power supply for the entire oven system.

[0057] The terminal block 310 of the power cord conduit 300 is used to reliably connect the wires inside the power cord conduit 300 to the power input terminal of the baking tray 200. Through the wires inside the power cord conduit 300 and the terminal block 310, electrical energy from the power bus is transmitted to the power input terminals of each baking tray 200. The power cord conduit 300 enables a modular design for the layered oven, allowing for easy disassembly or repair of a specific baking tray 200 by simply disconnecting the corresponding terminal block 310 from the power cord conduit 300, eliminating the need for extensive disassembly of the entire oven system and reducing maintenance and time costs. The standardized design of the terminal block 310 and the baking tray 200 allows for production on the same assembly line, improving production efficiency, shortening the production cycle, and reducing production costs. Furthermore, standardization ensures good compatibility and interchangeability between different baking trays 200, further reducing production costs and enhancing the versatility and flexibility of the baking trays 200.

[0058] In one embodiment, such as Figure 2 and Figure 3 As shown, the baking box 200 includes:

[0059] The box body 210 has a placement opening at one end and an air vent 211 at the other end. The placement opening is equipped with an openable door 212. The air vent 211 at the other end of the box body 210 is used to release the heat and moisture generated during the baking process, ensuring that the temperature and humidity inside the box body 210 reach the ideal baking conditions. The openable door 212 at the placement opening is used to seal the box body 210 to prevent heat loss and to open it when needed to put in or take out food.

[0060] A baking assembly is disposed inside the housing 210; the baking assembly is used to bake food; the baking assembly is disposed inside the housing 210 and is used to bake food. It may include heating elements (such as heating wires, heating tubes, etc.) and temperature sensors to ensure that the temperature inside the housing 210 reaches a predetermined baking temperature.

[0061] An electronic control component 220 is disposed outside the housing 210 and electrically connected to the power bus via a power input terminal. The output terminal of the electronic control component 220 is electrically connected to the baking assembly. The electronic control component 220 is used to control the operation of the baking assembly. The electronic control component 220's location outside the housing 210 and its electrical connection to the power bus via a power input terminal allows it to receive electrical energy from the power bus and convert it into the specific form of electrical energy required by the baking assembly. The output terminal of the electronic control component 220, electrically connected to the baking assembly, is used to control the operating state of the baking assembly. This may include adjusting the power of the heating element, monitoring temperature sensor readings, and adjusting baking parameters (such as temperature, time, etc.) as needed.

[0062] In one embodiment, the baking box 200 further includes:

[0063] The frame 230 is located on the outside of the box body 210; the frame 230 is used for connecting two adjacent baking boxes 200 / connecting the baking box 200 with the box body 100; the electronic control component 220 is fixedly installed on the frame 230.

[0064] In this embodiment, the baking tray 200 includes a frame 230 located on the outside of the box body 210. The frame 230 is typically made of a robust metal material (such as stainless steel or aluminum alloy) to ensure sufficient strength and stability. The frame 230 is designed with connecting structures (such as snap-fits and bolt holes) for connecting adjacent baking trays 200. This allows the baking trays 200 to be stacked together to form a multi-layer oven structure. Simultaneously, the connecting structures on the frame 230 also serve to connect the baking trays 200 to the oven body 100. This ensures that the baking trays 200 are securely installed within the oven body 100 and will not shift or detach during baking. The electrical control component 220 is fixedly mounted on the frame 230, which facilitates the electrical connection between the electrical control component 220 and the baking components and ensures the stability and safety of the electrical control component 220. By mounting the electronic control component 220 on the frame 230, the electronic control component 220 can also be connected to the control panel 150 or other control devices outside the oven body 100, making it convenient for users to operate and control.

[0065] It is worth noting that the frame of this embodiment is not the outer frame of a layered oven composed of multiple independent oven units stacked together. The frame of this embodiment is just a fixed support composed of frame strips. It does not have the structure of top plate 110, bottom plate 120 or side plate 140. Its actual purpose is to provide support for the baking box 200 and to realize the connection between two adjacent baking boxes 200 or the connection between the baking box 200 and the box body 100.

[0066] In one embodiment, the baking box 200 body further includes:

[0067] The back panel 240 is provided with an air vent 211. The back panel 240 is an important component of the baking box 200 body. It is located at the rear end of the box body 210 and together with the other parts of the box body 210, it forms a closed baking space. The air vent 211 on the back panel 240 is used to expel hot air and moisture from inside the box body 210 during the baking process, so as to maintain the temperature and humidity inside the box body 210 within a suitable range.

[0068] A duct assembly 250 is provided, with one end connected to the air outlet 211 of the back panel 240 and the other end connected to the outlet of the box body 210. The duct assembly 250 is used to open or close the air outlet 211 of the back panel 240 and the outlet of the box body 210 during operation. The design of the duct assembly 250 allows for the opening or closing of the air outlet 211 of the back panel 240 and the outlet of the box body 210 during operation, thereby achieving precise control of heat transfer within the box body 210. When the duct assembly 250 is open, hot air and moisture can be smoothly discharged from the box body 210 through the air outlet 211 and the duct assembly 250, achieving effective heat transfer and dissipation. When the duct assembly 250 is closed, the flow of hot air and moisture within the box body 210 is restricted, which can maintain a stable temperature within the box body 210, extend baking time, or achieve specific baking effects.

[0069] In one embodiment, the layered oven includes:

[0070] A duct 400 is disposed on the side of the back panel 240 facing away from the box body 210. The duct 400 is used to change the air outlet direction of the baking chamber. The main function of the duct 400 is to change the air outlet direction of the baking chamber, so that hot air or fumes can flow along a predetermined path and finally be discharged upward through the air outlet 211, to prevent fumes from flowing back and to avoid secondary contamination of the food by fumes or fumes flowing towards the wall facing the back panel 240 and causing wall contamination.

[0071] In one embodiment, the back plate 240 is provided with a power hole for connecting the power cord 300 to the power bus. The main function of the power hole is to provide a connection channel between the power cord 300 and the power bus. Through the power hole, the oven's power bus can be safely and reliably connected to an external power source, ensuring the oven's normal operation. Considering the standardized design of the terminal block 310 and the baking tray 200 described in the above embodiment, it can be understood that the back plate 240 on the baking tray 200 is designed with a unified standard for power holes. Therefore, during installation, there is no need to consider the installation order of the baking trays 200; the power cord 300 and the power bus can be connected through the power hole of the baking tray 200.

[0072] In one embodiment, such as Figure 4 As shown, the housing 100 includes:

[0073] Top plate 110; bottom plate 120; panel frame 130, the panel frame 130 is disposed on the side of the baking box 200 body facing away from the back plate 240, one end of the panel frame 130 is connected to the top plate 110 in the vertical direction and the other end is connected to the bottom plate 120, the panel frame 130 is provided with a placement groove for accommodating the control panel 150; side plate 140, the side plate 140 is disposed on opposite sides of the baking box 200 body, one end of the side plate 140 is connected to the top plate 110 in the vertical direction and the other end is connected to the bottom plate 120; the top plate 110, bottom plate 120, panel frame 130 and side plate 140 are respectively connected to the frame 230 of the baking box 200 body.

[0074] The oven body 100 is the main component of the oven, providing an enclosed space to house key components such as the baking tray 200 and the control panel 150. The oven body 100 typically consists of a top plate 110, a bottom plate 120, a panel frame 130, and side plates 140, which connect to the frame 230 of the baking tray 200 to form a complete and stable oven structure. It is worth noting that, to facilitate the installation and removal of the baking tray 200, the back plate 240 is located on the baking tray 200 and not on the oven body 100.

[0075] In one embodiment, the housing 100 further includes:

[0076] The control panel 150 is disposed on the placement slot of the panel frame 130. The control panel 150 is electrically connected to the electronic control component 220. The control panel 150 is used to display the working status of the baking chamber and, when operated by the user, input corresponding command information to the electronic control component 220.

[0077] The control panel 150 is electrically connected to the electronic control component 220 (such as a circuit board, sensors, etc.) to display the working status of the baking chamber (such as temperature, time, etc.) and receive user operation commands. When the user operates the control panel 150, such as setting baking temperature, time, or other parameters, the control panel 150 sends the corresponding command information to the electronic control component 220. The electronic control component 220 then controls the working status of the oven's heating elements, fans, and other components according to these commands, thereby achieving automated control of the baking process.

[0078] In one embodiment, the layered oven further includes:

[0079] Rollers are mounted at the bottom of the oven body 100; and / or adjustable support feet are mounted at the bottom of the oven body 100. The rollers at the bottom of the oven body 100 allow the oven to be easily moved on the floor or worktable. The rollers are typically made of wear-resistant, quiet materials to ensure stability and quiet operation during movement. Additionally, some rollers are equipped with brakes to prevent the oven from sliding unnecessarily when movement is not required.

[0080] Adjustable support feet are also installed at the bottom of the oven body 100. Unlike the casters, they are mainly used to adjust the height and level of the oven. Adjustable support feet usually have a threaded structure, allowing users to adjust their height by rotating the support feet, thus enabling the oven to reach the desired height and level. In addition, adjustable support feet can also compensate for uneven ground to some extent, allowing the oven to be placed stably on any surface.

[0081] In practical applications, casters and adjustable feet can be used individually or in combination to meet user needs in different scenarios. For example, a user can first use the casters to move the oven to the desired position, and then adjust the adjustable feet to ensure the oven's height and level.

[0082] The above embodiments are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
