Abstract
Description
Technical Field
[0001] This application relates to the technical field of household appliances, and in particular to a smart bread maker. Background Technology
[0002] A bread machine is an appliance that, after the flour and other ingredients are added, can automatically complete the bread-making process, including kneading, fermentation, and baking, according to a set program.
[0003] Early bread machines typically had several preset speeds, each corresponding to different amounts of cooking ingredients. When making bread, users needed to use measuring cups, spoons, and other tools to measure the ingredients for the corresponding speed, which was inconvenient.
[0004] To enable weighing, some manufacturers have added a weighing function to bread machines, allowing them to automatically weigh the bread. However, the weighing process is prone to errors, causing the weight to not match the setting and resulting in bread-making failure.
[0005] To achieve greater intelligence, Chinese utility model patent CN203226202U discloses an intelligent bread maker. It uses a weight acquisition device installed at the bottom of the main body to collect the weight signal of the bread maker. The main controller is connected to the water pump and heating device. Based on the weight signal, it calculates the amount of water to be added, the fermentation time and temperature, and realizes the calculation of the production process based on any amount of flour added by the user.
[0006] However, with existing bread machines, users can only know the bread's quality after it's made. Furthermore, if problems such as bread making failure, excessively dark color, or poor fermentation occur, users can only passively accept the situation or make the bread again. Utility Model Content

[0034] A bread machine is an appliance that, after the flour and other ingredients are added, can automatically complete the bread-making process, including kneading, fermentation, and baking, according to a set program.
[0035] Early bread machines typically had several preset speeds, each corresponding to different amounts of cooking ingredients. When making bread, users needed to use measuring cups, spoons, and other tools to measure the ingredients for the corresponding speed, which was inconvenient.
[0036] To enable weighing, some manufacturers have added a weighing function to bread machines, allowing them to automatically weigh the bread. However, the weighing process is prone to errors, causing the weight to not match the setting and resulting in bread-making failure.
[0037] To achieve greater intelligence, Chinese utility model patent CN203226202U discloses an intelligent bread maker. It uses a weight acquisition device installed at the bottom of the main body to collect the weight signal of the bread maker. The main controller is connected to the water pump and heating device. Based on the weight signal, it calculates the amount of water to be added, the fermentation time and temperature, and realizes the calculation of the production process based on any amount of flour added by the user.
[0038] However, with existing bread machines, users can only know the bread's quality after it's made. If problems arise, such as failed bread making, over-baking, or poor fermentation, users can only passively accept the result or try making it again. In other words, existing bread machines still fail to meet users' expectations of being able to know the bread's quality after it's been made.
[0039] To address this technical problem, this application provides a smart bread maker, which allows users to at least obtain the bread maker's baking status when using it.
[0040] like Figure 1-4 As shown, in an exemplary embodiment, the smart bread maker 10 of this application includes: a microcontroller 100, an operation module 200, a weighing module 300, an actuator 400, a wireless communication module 500, and a camera module 600. Among them,
[0041] The operation module 200 is used to generate operation command signals based on user operations. The operation module includes a touch button and a touch detection unit electrically connected to the touch button, the touch detection unit being connected to a microcontroller. Specifically, when the user operates the touch button, the touch detection unit generates different operation command signals, such as high and low voltage levels, and outputs them to the connected microcontroller.
[0042] The microcontroller 100, connected to the operation module 200, is used to send an instruction pulse signal upon receiving the operation instruction signal. The microcontroller may be a single-chip microcomputer (MCU), which sends an instruction pulse signal to the weighing module 300 upon receiving the operation instruction.
[0043] The weighing module 300 is used to receive the command pulse signal and return a weight data signal. The weighing module 300 includes a pressure sensor 310 and a weighing detection unit 320 connected to the pressure sensor. The weighing detection unit is connected to the microcontroller 100. In some preferred embodiments, the microcontroller 100 is electrically connected to the weighing module 300 via a power board 700.
[0044] The actuator 400 is electrically connected to the microcontroller, which also receives the weight data signal and outputs a first control signal to control the operation of the actuator. The actuator includes a water supply device 410, a stirring device 420, and a heating device 430. In some preferred embodiments, the microcontroller 100 is electrically connected to the actuator 400 via a power board 700; specifically, the water supply device, stirring device, and heating device are connected to the power board 700.
[0045] The wireless communication module 500 is connected to the microcontroller 100 and is used to send a second control signal output by the microcontroller. Specifically, the wireless communication module can be a WiFi module. Specifically, the second control signal is an image acquisition command, wherein the image acquisition command can be output when the microcontroller receives an image viewing command signal sent by the user from the mobile terminal, or when the bread maker starts working, or when the bread maker is triggered by preset conditions; this application does not limit this.
[0046] The camera module 600 is communicatively connected to the wireless communication module 500, and is used to receive and capture cooking status images according to the second control signal; the wireless communication module 500 is also used to send the cooking status images to the mobile terminal 20 for display, and the mobile terminal 20 and the camera module 600 are on the same local area network. The mobile terminal 20 is one or more of a mobile phone, PAD, computer, or dedicated device.
[0047] In the intelligent bread maker of this application embodiment, the microcontroller can output a second control signal and transmit it to the camera module through the wireless communication module to control the camera module to work, so as to obtain cooking status images. Furthermore, it can transmit the cooking status graphics to the mobile terminal and display them through the wireless communication module, so that the user can at least view the cooking images of the bread in real time during the bread making process to understand the cooking effect, thereby making it possible to intervene in bread making in advance.
[0048] It should be noted that the inventive concept of this application lies in setting up a wireless communication module and a camera module on the bread maker, connecting the camera module and a mobile terminal to the same local area network, and the signal connection and transmission structure between the various modules. Specifically, this application embodiment sets up a second control signal output from the microcontroller, which is sent to the camera module via the wireless communication module to control the operation of the camera module, and then sends the cooking status image to the mobile terminal located on the same local area network as the camera module via the wireless communication module, so that the user can view the bread making status.
[0049] In some embodiments, the weighing detection unit 320 includes a weighing detection chip U6. The pressure sensor 310 includes an excitation positive pin E+, an excitation negative pin E-, a signal positive pin S+, and a signal negative pin S-. The second terminal of the excitation positive pin E+ is connected to the output voltage of a switching power supply, and the second terminal of the excitation negative pin E- is grounded to power the pressure sensor. The signal positive pin S+ is connected to the positive input pin INPA of the weighing detection chip U6, and the signal negative pin S- is connected to the negative input pin INNA of the weighing detection chip to transmit the differential signal from the pressure sensor to the weighing detection chip.
[0050] One pin, DVDD, of the weighing detection chip is connected to the voltage input terminal of the switching power supply. The weighing detection chip also includes a clock input pin, PD_SCK, for receiving the pulse signal, and a data output pin, DOUT, for outputting weight data signals. The clock input pin, PD_SCK, and the data output pin, DOUT, are connected to the microcontroller 100. Specifically, the weighing detection chip can output weight data signals based on the differential signal from the pressure sensor. In some embodiments, the weighing detection chip may be an HX711.
[0051] The weighing module also includes an inductor L4 and a capacitor C27. The first end of the inductor L4 is connected to the output voltage of the switching power supply, and the second end is connected to the second end of the excitation positive pin E+. One end of the capacitor C27 is grounded for filtering, and the other end is connected to the second end of the inductor L4, forming an LC filter with the inductor L4 to isolate digital noise from the analog power supply.
[0052] The weighing module also includes resistors R61 and R66. Resistor R61 is connected between the positive signal pin S+ and the positive input pin of the weighing detection chip U6; resistor R66 is connected between the negative signal pin S- and the negative input pin of the weighing detection chip. These are used for current limiting or impedance matching to prevent signal reflection.
[0053] The weighing module also includes a capacitor C31, one end of which is connected between the resistor R61 and the positive input pin, and the other end is connected between the resistor R66 and the negative input pin. Capacitor C31 is used to filter out noise and ensure a stable reference voltage. Figure 3 The switching power supply output voltage is +5V.
[0054] In some exemplary embodiments, the wireless communication module 500 is further configured to send the cooking status image to the cloud server 30, and the cloud server 30 is configured to output a cloud adjustment command signal based on the cooking status image. The wireless communication module 500 is also configured to receive the cloud adjustment command signal from the cloud server 30, and the microcontroller 100 is further configured to output a third control signal based on the cloud adjustment command signal from the cloud server 500 to control the actuator. In this embodiment, the signal flow structure is as follows: the cooking status image is transmitted to the cloud server via the wireless communication module; after receiving it, the cloud server outputs a cloud adjustment command signal based on the cooking status image, which is then sent to the microcontroller via the wireless communication module. The microcontroller then outputs a third control signal to control the actuator. The method by which the cloud server outputs the cloud adjustment command signal based on the cooking status image, and the method by which the microcontroller outputs the third control signal based on the cloud adjustment command signal, are not within the scope of this application and can be implemented using existing technologies in the field. For example, the cooking status can be identified using image recognition technology, and then matched with the corresponding time. If the corresponding time of the cooking status is greater than the current time, it indicates overcooking and the cooking power needs to be reduced, thus outputting a cloud adjustment command signal.
[0055] In other exemplary embodiments, the cloud server 30 is connected to the smart speaker 40 to receive voice commands from the smart speaker and output cloud command signals. The wireless communication module 500 is also used to receive cloud command signals from the cloud server 30, and the microcontroller 100 is also used to output a third control signal based on the cloud command signals from the cloud server 30 to control the operation of the actuator 400. In this embodiment, the signal flow structure is as follows: the voice commands from the smart speaker are transmitted to the cloud server, the cloud server outputs cloud command signals which are transmitted to the microcontroller via the wireless communication module, and then the microcontroller outputs a third control signal to control the operation of the actuator. The method by which the cloud server generates cloud command signals based on voice commands and the microcontroller outputs third control signals based on cloud command signals can also be implemented using existing technology, and is not within the scope of protection of this application embodiment; therefore, this application does not impose any restrictions on this method.
[0056] In other exemplary embodiments, the mobile terminal 20 is further configured to output a terminal instruction signal according to user instructions. The wireless communication module 500 is further configured to receive the terminal instruction signal from the mobile terminal 20; the microcontroller 100 is further configured to output a third control signal according to the terminal instruction signal from the mobile terminal to control the operation of the actuator 400. In this embodiment, the signal flow structure is as follows: the mobile terminal outputs a terminal instruction signal according to user instructions, the terminal instruction signal is transmitted to the microcontroller via the wireless communication module, and then the microcontroller outputs a third control signal to control the operation of the actuator. The method of the mobile terminal outputting a terminal instruction signal according to user instructions and the microcontroller outputting a third control signal according to the terminal instruction signal can also be implemented using existing technology, and is not within the protection scope of this application embodiment; therefore, this application does not impose any restrictions on it.

Furthermore, this invention can take the form of a computer program product implemented on one or more computer-usable storage media (including but not limited to disk storage, CD-ROM, optical storage, etc.) containing computer-usable program code.
