Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a toaster. Background Technology

[0002] Traditional multi-cavity toasters employ multiple independent control systems, meaning each cavity has its own lifting mechanism, handle, and other components to independently drive each cavity. However, this structure leads to redundant component design, increased manufacturing costs, and a higher failure rate. For example, Chinese patent CN101984902B discloses a four-cavity toaster with independent control units. It includes a housing assembly containing two independent heating units. Each heating unit comprises two side-by-side heating chambers and a heating mesh frame within each chamber. Each heating unit has its own independent control unit. Clearly, this four-cavity toaster suffers from redundant component design, increased manufacturing costs, and a higher failure rate. Utility Model Content

[0003] To address the aforementioned technical problems in the existing technology, this utility model provides a toaster oven that can drive the movement of all pushers through a lifting and lowering assembly, and can also control multiple heating furnace bodies through a control assembly, thus achieving integrated component design and effectively reducing product manufacturing costs.

[0004] This application provides a toaster oven, including:

[0005] The machine body is provided with multiple heating furnaces, and each heating furnace is provided with at least one pusher bar.

[0006] A lifting handle assembly includes a handle and a connector connected to each other. The handle is mounted on the body in a liftable manner. The connector is connected to a plurality of push bars. The handle is used to drive the push bars to perform lifting and lowering movements through the connector.

[0007] A switch is provided on the machine body, and the handle lifting assembly is used to trigger the switch when the machine moves down to a preset position;

[0008] A control component, electrically connected to the plurality of heating furnace bodies and switching elements respectively, is used to receive feedback signals generated after the switching elements are triggered, and to control at least one of the plurality of heating furnace bodies to be in a heating state. This structure enables the movement of all push bars through a single lifting and lowering assembly, while also allowing control of multiple heating furnace bodies through a single control component. This integration of component design effectively reduces product manufacturing costs.

[0009] In some embodiments, the handle lifting assembly further includes a magnetic component disposed on the connector, and the toaster further includes an electromagnet disposed on the body. The magnetic component and the electromagnet are arranged vertically correspondingly. After the magnetic component moves to the preset position under the drive of the connector, it remains at the preset position under the magnetic field of the electromagnet. In this way, the electromagnet attracts the magnetic component, enabling the magnetic component to drive the handle lifting assembly to remain at the preset position, allowing the bread to be fully heated in the heating oven without the user having to constantly apply force to the handle. The design of the electromagnet and the magnetic component is simple and the structure is reasonable.

[0010] In some embodiments, the control component is electrically connected to the electromagnet, and the control component is further configured to control the electromagnet to be energized after receiving a feedback signal generated after the switch is triggered, so that the electromagnet can attract the magnetic component, thereby enabling the magnetic component to be held in a preset position under the action of the magnetic field of the electromagnet when the electromagnet is energized, and the magnetic component will be unable to be held in the preset position when the electromagnet is de-energized and the attraction force is removed.

[0011] In some embodiments, the control component is further configured to control the electromagnet to be de-energized after at least one of the plurality of heating oven bodies has been in a heating state for a preset time, thereby releasing the magnetic component. Thus, after the heating oven body has heated the bread for the preset time, the electromagnet can be de-energized to remove the attraction to the magnetic component, preventing the magnetic component from remaining in the preset position and achieving the purpose of releasing the magnetic component.

[0012] In some embodiments, the handle lifting assembly further includes an elastic element, one end of which is connected to the machine body and the other end to the connecting member. The elastic element applies a force to the connecting member to cause the push bar to move upward, so that after the electromagnet releases the magnetic element, the handle lifting assembly moves away from the switch element under the action of the elastic element. Thus, by having the elastic element act on the handle lifting assembly to reset it after the electromagnet releases the magnetic element, the bread on the push bar can be directly pushed out of the heating oven body, simplifying the user's operation.

[0013] In some embodiments, the electromagnet has an operating surface that conforms to the magnetic element, and the electromagnet has a through groove extending through the operating surface. The switching element includes a movable structure that extends through the through groove and retracts into the through groove under the action of the magnetic element when the magnetic element is in contact with the operating surface. The positional relationship between the electromagnet and the movable structure of the switching element is more compact, enabling the switching element to be triggered by the magnetic element acting on the movable structure, thus simplifying the structural design of the handle lifting assembly.

[0014] In some embodiments, the heating furnace body is provided with a pressure sensor electrically connected to the control component. The pressure sensor is used to detect the weight information of the food on the pusher. The control component is also used to receive the weight information of the food detected by the pressure sensor and control the corresponding heating furnace body to be in a heating state. This achieves the goal of automatically determining the heating furnace body to be operated based on the weight information of the food detected by the pressure sensor, without requiring the user to select the heating furnace body to be operated.

[0015] In some embodiments, the toaster has a first operating mode in which one of the heating elements operates and a second operating mode in which multiple heating elements operate simultaneously. The toaster body is equipped with a control component electrically connected to the control assembly. The control assembly is further configured to receive an operation command that triggers the control component, controlling the toaster to operate in either the first or second operating mode. Thus, the user can manually select the toaster to enter either the first or second operating mode via the control component, allowing for convenient selection based on user needs.

[0016] In some embodiments, the machine body is provided with a guide rod, and each heating furnace body is also provided with a mounting component for installing the push bar therein. The connecting component is connected to the push bar through the mounting component. Both the mounting component and the connecting component are sleeved on the guide rod to move up and down along the length of the guide rod. In this way, the mounting component and the connecting component can move up and down stably along the guide rod, thereby enabling the handle lifting assembly to move up and down as a whole, ensuring the reliability of the handle lifting assembly's up and down movement.

[0017] In some embodiments, there are two heating oven bodies, and each heating oven body is provided with two pushers, with the four pushers arranged side by side. This structural design is reasonable and enables the simultaneous heating of multiple slices of bread.

[0018] Compared with the prior art, the beneficial effects of this utility model embodiment are as follows: This utility model has multiple heating furnaces on the machine body, and the handle lifting component is connected to the push bars in each heating furnace. It can realize that all push bars can be driven to move upward synchronously by one handle lifting component, and the handle lifting component can be lowered to trigger the switch, so that the control component can control at least one of the multiple heating furnaces to be in the heating state. That is, while the handle lifting component can drive all push bars to move, the control component can also control multiple heating furnaces. It can control multiple heating furnaces to enter the heating state synchronously, or it can control some heating furnaces, such as one heating furnace, to enter the heating state. It realizes the integration of component design, effectively reduces product manufacturing costs, and the control component can ensure the consistency of baking by controlling multiple heating furnaces to enter the heating state synchronously, so that the food heated by different heating furnaces is more even.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] This application provides a toaster oven. For example... Figures 1 to 6As shown, the toaster includes a body 1, a handle lifting assembly 2, a switch 3, and a control assembly 4. The body 1 has multiple heating chambers 11, each containing at least one pusher bar 12. The handle lifting assembly 2 includes a handle 21 and a connecting member 22 connected together. The handle 21 is mounted on the body 1 in a liftable manner, and the connecting member 22 is connected to all pushers 12. The handle 21 drives the pushers 12 to move up and down via the connecting member 22. The switch 3 is mounted on the body 1, and the handle lifting assembly 2 triggers the switch 3 when it descends to a preset position. The control assembly 4 is electrically connected to the multiple heating chambers 11 and the switch 3, respectively. The control assembly 4 receives the feedback signal generated after the switch 3 is triggered and controls at least one of the multiple heating chambers 11 to be in a heating state.

[0030] like Figure 1 and Figure 2 As shown in the figure, there are two heating oven bodies 11, and each heating oven body 11 is provided with two pushers 12. That is, the toaster has four food slots, and each food slot corresponds to one pusher 12. Food is placed on the pusher 12 and can enter the heating oven body 11 for heating as the pusher 12 descends, or can be moved out of the heating oven body 11 when the pusher 12 rises.

[0031] By pushing or pulling the handle 21 downwards, the user can achieve the effect of multiple push bars 12 moving in tandem with a single handle. That is, one operation can drive all push bars 12 to descend synchronously, and all push bars 12 can move upwards synchronously with the handle 21.

[0032] The aforementioned handle lifting assembly 2 may also include a handle bracket 25, and the handle 21 can be connected to the connector 22 via the handle bracket 25.

[0033] The aforementioned handle lifting assembly 2 may be provided with a separate triggering part, which is used to trigger the switch 3 when it descends to a preset position. Of course, the function of the triggering part can also be realized by the handle 21, the connecting part 22 or other structures included in the handle lifting assembly 2, such as by the magnetic part 23 mentioned below, so that the switch 3 can be stably triggered when the handle lifting assembly 2 descends to the preset position.

[0034] The switch element 3 can be understood as a switch that can be triggered by an action, such as a spring switch. After being triggered, the switch element 3 can generate a feedback signal and send it to the control component 4. Based on the feedback information, the control component 4 can control all or part of the heating furnace body 11 to be in the heating state. That is, it can control multiple heating furnace bodies 11 to enter the heating state simultaneously, or it can control some heating furnace bodies 11, such as controlling one heating furnace body 11 to enter the heating state alone.

[0035] It should be noted that the control component 4 can be constructed using electronic components such as timers, comparators, registers, and digital logic circuits, or implemented using processor chips such as microcontrollers, microprocessors, programmable logic controllers (PLCs), digital signal processors (DSPs), field-programmable gate arrays (FPGAs), programmable logic arrays (PLAs), and application-specific integrated circuits (ASICs) and their peripheral circuits.

[0036] This invention features multiple heating ovens 11 mounted on the main body 1. A handle lifting assembly 2 is connected to push bars 12 within each heating oven 11. This allows all push bars 12 to move synchronously upwards via a single handle lifting assembly 2. Furthermore, the handle lifting assembly 2 can lower to trigger a switch 3, enabling a control assembly 4 to control at least one of the multiple heating ovens 11 to be in a heating state. This means that while one handle lifting assembly 2 moves all push bars 12, a single control assembly 4 can simultaneously control multiple heating ovens 11, allowing them to enter the heating state synchronously or only one oven 11. This integrated component design effectively reduces manufacturing costs. Moreover, the control assembly 4 ensures consistent baking by controlling multiple heating ovens 11 to enter the heating state simultaneously, resulting in more uniform heating of food from different ovens 11.

[0037] In some embodiments, such as Figures 2 to 6 As shown, the handle lifting assembly 2 also includes a magnetic component 23 disposed on the connector 22, and the toaster also includes an electromagnet 5 disposed on the body 1. The magnetic component 23 and the electromagnet 5 are arranged vertically and vertically respectively. After the magnetic component 23 moves to a preset position under the drive of the connector 22, it remains in the preset position under the action of the magnetic field of the electromagnet 5.

[0038] In this way, the electromagnet 5 attracts the magnetic component 23, which in turn drives the handle lifting assembly 2 to remain in the preset position, so that the food can be fully heated in the heating furnace body 11 without the user having to constantly apply force to the handle component 21. The design of the electromagnet 5 and the magnetic component 23 is simple and the structure is reasonable.

[0039] The lower part of the aforementioned magnetic component 23 may have a magnetic attraction surface, which can fully contact the electromagnet 5 to ensure a stable magnetic attraction effect between the magnetic component 23 and the electromagnet 5. Specifically, the magnetic component 23 may be in the form of a thin plate, with its lower plate surface being the aforementioned magnetic attraction surface.

[0040] The aforementioned handle lifting assembly 2 may also include a frame disposed on the connector 22, and a magnetic component 23 may be installed on the frame.

[0041] In some embodiments, the control component 4 is electrically connected to the electromagnet 5, and the control component 4 is also used to control the electromagnet 5 to be energized after receiving a feedback signal generated after the switch 3 is triggered, so that the electromagnet 5 can attract the magnetic component 23.

[0042] Thus, the electromagnetic 5 can be energized to generate a magnetic field by the control component 4, or the generated magnetic field can be eliminated by de-energizing it. This allows for precise control of the interaction between the electromagnetic 5 and the magnetic component 23, namely the attraction relationship after energization and the independent relationship after de-energization. This ensures that when the electromagnetic 5 is energized, the magnetic component 23 can be kept in a preset position under the action of the magnetic field of the electromagnetic 5. When the electromagnetic 5 is de-energized, the attraction force is removed, and the magnetic component 23 will no longer be able to stay in the preset position.

[0043] The electromagnet 5 and the switch 3 can be arranged close to each other so that the electromagnet 5 can be energized directly after the switch 3 is triggered, thereby attracting the magnetic component 23. The above structural design is more compact and reasonable.

[0044] In some embodiments, the control component 4 is further configured to control the electromagnet 5 to be de-energized after at least one of the plurality of heating furnace bodies 11 has been in a heating state for a preset time, so as to release the magnetic element 23.

[0045] In this way, after the heating furnace body 11 has heated the food for a preset time, the electromagnet 5 can be de-energized to remove the attraction of the magnetic component 23, so that the magnetic component 23 can no longer remain in the preset position, thereby achieving the purpose of releasing the magnetic component 23.

[0046] The preset time mentioned above can be understood as the baking time for food. Once the preset time is reached, the baking of the food is complete.

[0047] In some embodiments, such as Figures 2 to 5 As shown, the handle lifting assembly 2 also includes an elastic element 24. One end of the elastic element 24 is connected to the body 1, and the other end is connected to the connector 22. The elastic element 24 is used to apply a force to the connector 22 to drive the push bar 12 to move upward, so that after the electromagnet 5 releases the magnetic element 23, the handle lifting assembly 2 moves away from the switch element 3 under the action of the elastic element 24.

[0048] In this way, after the electromagnet 5 releases the magnetic element 23, the elastic element 24 acts on the handle lifting assembly 2 to reset it, so that the food on the push bar 12 can be directly pushed out of the heating furnace body 11, simplifying the user's operation steps.

[0049] The aforementioned elastic element 24 can be specifically a tension spring. When the electromagnet 5 and the magnetic element 23 are attracted to each other, the elastic element 24 is in a stretched state. After the electromagnet 5 releases the magnetic element 23, the elastic element 24 will drive the handle lifting assembly 2 to reset as a whole, that is, move away from the switch element 3.

[0050] In some embodiments, such as Figure 2 and Figure 3 As shown, the electromagnet 5 has an action surface that is in contact with the magnetic component 23, and the electromagnet 5 is provided with a through groove that passes through the action surface. The switch component 3 includes a movable structure 31, which passes through the through groove and retracts into the through groove under the action of the magnetic component 23 when the magnetic component 23 is in contact with the action surface.

[0051] The positional relationship between the electromagnet 5 and the movable structure 31 of the switch 3 is more compact, enabling the switch 3 to be triggered by the magnetic element 23 acting on the movable structure 31, thus simplifying the structural design of the handle lifting assembly 2. After the magnetic element 23 acts on the movable structure 31, it can directly contact the working surface of the electromagnet 5.

[0052] When the movable structure 31 of the aforementioned switch 3 is pushed back into the through slot, it can be understood that the switch 3 is triggered and can generate a feedback signal.

[0053] In some embodiments, the heating furnace body 11 is provided with a pressure sensor (not shown in the figure) electrically connected to the control component 4. The pressure sensor is used to detect the weight information of the food on the pusher 12. The control component 4 is also used to receive the weight information of the food detected by the pressure sensor and control the corresponding heating furnace body 11 to be in a heating state.

[0054] In this way, the weight information of the food on the pusher 12 can be detected by the pressure sensor, thereby determining whether there is food on the pusher 12. This allows the control component 4 to control the heating oven body 11 corresponding to the pusher 12 with food to be in a heating state, heating the food inside. The heating oven body 11 corresponding to the pusher 12 without food can not work, that is, it does not need to be heated. This achieves the goal of automatically determining the heating oven body 11 to be worked based on the weight information of the food detected by the pressure sensor, without the user having to select which heating oven body 11 to work.

[0055] The aforementioned food weight information indicates whether there is food on the pusher 12, and also indicates the specific weight of the food on the pusher 12, such as one slice of bread, two slices of bread, etc. The control component 4 can adjust the specific heating parameters of the heating furnace body 11 when it is in the heating state according to the food weight information, such as heating time, heating power, etc.

[0056] In some embodiments, the toaster has a first working mode in which one heating furnace body 11 operates and a second working mode in which multiple heating furnace bodies 11 operate simultaneously. The body 1 is provided with a control element 13 electrically connected to the control component 4. The control component 4 is also used to receive operation instructions that trigger the control element 13 and control the toaster to operate in the first working mode or the second working mode.

[0057] In this way, users can manually select the toaster to enter the first working mode or the second working mode through the control component 13, which allows users to choose according to their needs.

[0058] For example, Figure 1 The diagram shows two heating furnace bodies 11. The simultaneous operation of both heating furnace bodies 11 can be understood as the second working mode, while the operation of only one heating furnace body 11 can be understood as the first working mode.

[0059] In some embodiments, such as Figure 4 and Figure 5 As shown, the machine body 1 is provided with a guide rod 6, and each heating furnace body 11 is also provided with an installation part 14 for installing its inner push bar 12. The connecting part 22 is connected to the push bar 12 through the installation part 14. The installation part 14 and the connecting part 22 are both sleeved on the guide rod 6 so as to move up and down along the length direction of the guide rod 6.

[0060] In this way, the mounting part 14 and the connecting part 22 can move up and down stably along the guide rod 6, thereby enabling the handle lifting assembly 2 to move up and down as a whole, ensuring the reliability of the handle lifting assembly 2's up and down movement.

[0061] The aforementioned guide rod 6 can be multiple, and multiple guide rods 6 work together to guide the installation component 14 and the connector 22 to move in the vertical direction.

[0062] In some embodiments, such as Figure 1 and Figure 2 As shown, there are two heating oven bodies 11, and each heating oven body 11 is equipped with two pushers 12, with the four pushers 12 arranged side by side. The above structural design is reasonable and can realize the function of heating multiple slices of bread at the same time.

[0063] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. Those skilled in the art can make various modifications or equivalent substitutions to this utility model within its substance and protection scope, and such modifications or equivalent substitutions should also be considered to fall within the protection scope of this utility model.
