Technical Field

[0001] This application relates to the technical field of bread machines, specifically sandwich bread machines. Background Art

[0002] A sandwich bread machine, also known as a sandwich maker or breakfast maker, is a multifunctional kitchen appliance mainly used for making sandwiches and other breakfast foods. The sandwich maker toasts two slices of bread until crispy through a heating element, and various ingredients can be added to make sandwiches at the same time.

[0003] When the existing sandwich bread machine heats bread, it only heats the bread by adjusting the preset temperature, performing a function of heating the bread. Among the bread to be heated, there is a category that is refrigerated and fresh-keeping. Due to being stored at a low temperature for a long time, the moisture inside the bread may condense into tiny ice crystals, and at the same time, the yeast activity will also be inhibited. When heating the refrigerated and fresh-keeping bread at the same temperature, these ice crystals absorb heat and melt, and then turn into water vapor. This process will affect the heating effect and taste of the bread.

[0004] Therefore, this application provides a sandwich bread machine to solve the above problems. Utility Model Content

[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0030] This embodiment provides a sandwich bread maker, as Figures 1-6 shown. The sandwich bread maker includes a lower heating table 1 and an opening and closing frame 3 provided on the lower heating table 1. An upper heating table 4 corresponding to the lower heating table 1 is installed at the upper end of the opening and closing frame 3. A control mechanism 2 is provided on one side of the lower heating table 1. Heating elements 22 are provided inside both the lower heating table 1 and the upper heating table 4;

[0031] The control mechanism 2 includes a control box 21, a temperature adjustment knob 24 and a timing knob 25 provided at the upper end of the control box 21, a control main board 26 provided inside the control box 21, and a buzzer 28 provided inside the control box 21 and connected to the control main board 26. The output ends of the temperature adjustment knob 24 and the timing knob 25 inside the control box 21 are connected to the input end of the control main board 26. A timer 27 is welded on the control main board 26, and a memory 29 is provided on the control main board 26. The heating elements 22 and temperature sensors 23 located inside the lower heating table 1 and the upper heating table 4 are both connected to the control main board 26. A display screen is provided on the outside of the control box 21 and on the side far from the control main board 26, and the output end of the display screen is connected to the output end of the control main board 26.

[0032] Specifically, the control main board 26 serves as the center of the entire control system, responsible for receiving user inputs such as the settings of heating temperature and time, and controlling the operation of other circuit components according to the preset program. The temperature adjustment knob 24 is used to adjust the preset heating temperature, the timing knob 25 is used to adjust the heating time, the temperature sensor 23 is used to monitor the heating temperature inside the sandwich toaster in real time, and feedback the temperature data to the control circuit. The control main board 26 adjusts the power of the heating element 22 according to the temperature data to maintain or change the heating temperature. The timer 27 cooperates with the control main board 26 to record the heating time, and sends a signal to the control main board 26 after reaching the preset time to end the current heating stage or enter the next heating stage, so as to achieve multi-stage heating temperature and heating time, and set different heating temperatures and heating times to make the crispy food reach the best edible effect. The buzzer 28 emits sound or light signals when the heating is over, the machine malfunctions, or the user needs to pay attention, so as to remind the user through mutual cooperation with the control main board 26.

[0033] Base plates 51 are provided on both the lower heating table 1 and the upper heating table 4. A heating plate 52 is provided at the upper end of the base plate 51. A concave platform is provided at the bottom of the heating plate 52, and the concave platform extends into the interior of the base plate 51 and is in contact with the heating element 22. Fixing components 5 are provided on both the base plate 51 and the heating plate 52.

[0034] More specifically, the concave platform at the bottom of the heating plate 52 is mainly in contact with the heating element 22, and when the heating element 22 generates heat and can heat the bread through the heating plate 52.

[0035] The fixing component 5 includes a plurality of fixing seats 55 equidistantly arranged on the upper end of the base plate 51. Grooves are formed in the fixing seats 55. A limiting rod 56 is movably inserted through one side of the fixing seat 55. The fixing component 5 further includes a plurality of hinge seats 53 arranged on the upper end of the heating plate 52. Limiting blocks 54 are hinged to the hinge seats 53 respectively. Slots corresponding to the limiting rods 56 are formed in the upper ends of the limiting blocks 54. A long strip plate is installed at one end of the limiting rod 56 away from the fixing seat 55. A spring 57 is arranged between the long strip plate and the fixing seat 55.

[0036] It should be noted that there are four groups of both the fixing seats 55 and the hinge seats 53, and they are horizontally aligned with each other. The limiting blocks 54 can rotate in angle by being hinged to the hinge seats 53. After the limiting rods 56 are pulled outwards, the limiting blocks 54 are rotated and placed in the grooves formed in the fixing seats 55. At this time, when the limiting rods 56 are released, the spring 57 can reset the limiting rods 56, so that the heating plate 52 is fixed to the base plate 51. During later disassembly, the limiting rods 56 are pulled out in sequence and the limiting blocks 54 are pushed away from the fixing seats 55, then the heating plate 52 can be separated from the base plate 51, which is convenient for later cleaning.

[0037] During use, by arranging a control main board 26 inside the control box 21 and connecting the heating element 22, the temperature sensor 23, the timer 27, the buzzer 28, the memory 29 and the display screen to the control main board 26 respectively, the user can set the heating temperature and heating time through buttons or knobs. These information are stored in the memory 29 and read by the lower heating table 1. The lower heating table 1 controls the power and working time of the heating element 22 according to the preset program and the current working state. At the same time, the heating temperature is monitored in real time through the temperature sensor 23, the timer 27 records the heating time, and sends a signal to the lower heating table 1 after reaching the preset time. The lower heating table 1 adjusts the working state of the heating element 22 according to the received signal, reduces the power or enters the next heating stage, so as to set the multi-stage heating temperature and heating time, and then set different heating temperatures and heating times to make the brittle food reach the best edible effect. When the bread crumbs on the heating plate 52 need to be cleaned later, the limiting rods 56 are pulled out in sequence and the limiting blocks 54 are pushed away from the fixing seats 55, then the heating plate 52 can be separated from the base plate 51, and the heating plate 52 can be cleaned alone. After the cleaning is completed, the limiting blocks 54 corresponding to each group of fixing seats 55 are installed in sequence.

[0038] The above is only the preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and its concept of the present application, makes equivalent replacements or changes, and should be covered within the protection scope of the present application.
