[0019] In the following, only certain exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than limiting.

[0020] Figure 1 shows a circuit structure diagram of a control circuit of a smoking, steaming and baking integrated machine according to an embodiment of the present application.

[0021] As shown in Figure 1 , the control circuit 100 of the smoking, steaming and baking integrated machine includes a display control group board 110, a power control group board 120 and a range hood frequency conversion control group board 130.

[0022] The display control group board 110 includes a range hood control signal output end 111 and a steaming and baking oven control signal output end 112. The display control group board 110 is configured to provide corresponding range hood control signals to the range hood control signal output end 111 or provide corresponding steaming and baking oven control signals to the steaming and baking oven control signal output end 112 in response to a touch operation on the display touch screen. For example, when the touch operation is a touch operation for controlling the range hood to work, the display control group board 110 provides corresponding range hood control signals to the range hood control signal output end 111. When the touch operation is a touch operation for controlling the steaming and baking oven to work, the display control group board 110 provides corresponding steaming and baking oven control signals to the steaming and baking oven control signal output end 112.

[0023] The power control group board 120 comprises: a hood control signal input end 121 connected with the hood control signal output end 111, a steaming oven control signal input end 122 connected with the steaming oven control signal output end 112, a hood driving signal output end 123, a hood DC output end 124 and a steaming oven DC output end 125. The power control group board 120 is used to provide the hood power DC to the hood DC output end 124 and provide the hood driving signal to the hood driving signal output end 123 in response to the hood control signal provided by the hood control signal input end 121. The power control group board 120 is also used to provide the steaming oven power DC to the steaming oven DC output end 125 in response to the steaming oven control signal provided by the steaming oven control signal input end 122. The steaming oven DC output end 125 is used to be connected with the DC input end of each component of the steaming oven, so that the steaming oven can be driven to work correspondingly.

[0024] It can be understood that the power control group board 120 further comprises an AC power input end 126 for external connection of an external power supply to provide power supply to the three group boards, the hood 150 and the steaming oven 140.

[0025] The hood variable frequency control group board 130 comprises: a hood DC input end 131 connected with the hood DC output end 124, a hood driving signal input end 132 connected with the hood driving signal output end 123, and a motor DC output end 133. The hood variable frequency control group board 130 is used to convert the hood power DC provided by the hood DC input end 131 into the motor power DC corresponding to the gear and provide the motor power DC to the motor DC output end 133 in response to the hood driving signal provided by the hood driving signal input end 132. The hood DC output end 124 of the power control group board 120 is connected with the hood DC input end 131 of the hood variable frequency control group board 130, so that the power control group board 120 provides the power DC to the hood variable frequency control group board 130 for power adjustment, and then the hood variable frequency control group board 130 provides the adjusted power DC to the hood motor 150. The hood driving signal output end 123 of the power control group board 120 is connected with the hood driving signal input end 132 of the hood variable frequency control group board 130. In this way, the hood variable frequency control group board 130 adjusts the received DC according to the driving signal provided by the power control group board 120 after obtaining the driving signal, and drives the motor of the hood to work by using the power DC corresponding to the gear.

[0026] According to the above embodiment, the control circuit of the integrated range hood, steam oven, and oven includes a display control board 110, a power control board 120, and a range hood frequency converter control board 130. The display control board 110, in response to touch operations on the display touchscreen, can provide corresponding range hood control signals and steam oven control signals to the power control board 120. When the power control board 120 receives a range hood control signal, it provides a range hood drive signal and DC power supply to the range hood frequency converter control board 130. Thus, when the range hood drive signal is received, the frequency converter control board 130 converts the DC power supply to the range hood into a corresponding motor power supply DC to control the range hood motor. When the power control board 120 receives a steam oven control signal, it provides steam oven power supply DC to the steam oven's DC output terminal 125 to drive the steam oven. Therefore, the control circuit of the integrated range hood, steam oven and oven of this utility model embodiment only requires three control boards, that is, to control the range hood and steam oven in a coordinated manner. Compared with the existing range hood and steam oven, it reduces two control boards, reduces the control complexity of the components, and saves hardware costs.

[0027] Figure 2 This is a circuit diagram of the control circuit of a smoke-steam-grill integrated machine according to another embodiment of this utility model.

[0028] In one implementation, such as Figure 2 As shown, the integrated steam oven can be equipped with a light 160, for example, installed in the steam oven. Therefore, the display control board 110 may also include a light control signal output terminal 113. The display control board 110 is also used to provide a corresponding light control signal to the light control signal output terminal 113 in response to touch operations on the touch screen. The power control board 120 also includes a light control signal input terminal 127 connected to the light control signal output terminal 113, and a light DC output terminal 128. The power control board 120 is also used to provide DC power to the light to the light DC output terminal 128 in response to the light control signal provided by the light control signal input terminal 127.

[0029] When a user taps the lighting icon or button on the touchscreen, the display control board 110 responds to the operation by providing a corresponding lighting control signal to its lighting control signal output terminal 113, such as a signal to turn on the lighting. This signal is then transmitted to the lighting control signal input terminal 127 of the power control board 120. Upon receiving the lighting control signal, the power control board 120 provides DC power to the lighting DC output terminal 128. The lighting DC output terminal 128 is connected to the power input terminal of the lighting lamp, thus driving the lighting lamp to operate.

[0030] Similarly, the lighting control signal can be a lighting off signal. When the power control board 120 receives this signal, it stops supplying DC power to the lighting DC output terminal 128.

[0031] According to the above implementation method, by working together with the display control board and the power control board 120, the lighting of the integrated smoke, steam and grill can be controlled to turn on or off.

[0032] In one implementation, such as Figure 2 As shown, the display control board 110 may also include a display board DC input terminal 114, and the power control board 120 may also include a display board DC output terminal 129 connected to the display board DC input terminal 114 to supply power to the display control board 110.

[0033] Of course, in some embodiments, the display control component may also be internally powered by a built-in power source such as a battery.

[0034] According to the above embodiments, the power control board 120 can provide power to the display control board 110, so that the display control board 110 can work normally.

[0035] Figure 3 This is a circuit diagram of a display control board according to an embodiment of the present invention.

[0036] In one implementation, such as Figure 3 As shown, the display control board 110 may include a third main control chip 310 and the aforementioned display touch screen 320. The control signal input terminal 116 of the third main control chip 310 is connected to the control signal output terminals 322 of each touch button corresponding to the touch screen 321 in the aforementioned display touch screen 320 to realize communication between the two. The control signal output terminals of the third main control chip 310 include the aforementioned range hood control signal output terminal 111, steam oven control signal output terminal 112, and lighting control signal output terminal 113. It may also include a working status output terminal 115, which is connected to the working status input terminal 324 of the display screen 323 in the display touch screen 320. When the display screen 323 receives a working status signal, it displays the corresponding working status on the display screen 323. For example, different combinations of text, color, and light are used to display the status at the position of the corresponding touch button. Alternatively, the relevant information of the working status can be displayed in text form within a designated display area. In practical applications, the touch screen and the display screen are roughly the same size, and the touch screen is located above the display screen. In some examples, the touchscreen can be a touch frame set on the four sides of the display.

[0037] Figure 4 This is a circuit diagram of a power control board according to an embodiment of the present invention.

[0038] In one embodiment, as shown in Figure 4 The power control group board 120 further includes a power conversion module 410, a first master control chip 420, a steaming oven component switch circuit 430 and a lighting lamp switch circuit 440.

[0039] It can be understood that the steaming oven 140 includes a plurality of components to realize a plurality of cooking functions of the steaming oven. For example, the steaming oven includes a heating tube, an evaporator, a baking lamp, a water tank, a water pump, a fan and some sensors. The sensors can include sensors arranged in the oven, such as temperature sensors, pressure sensors and flow sensors, etc. It can also include sensors arranged near the evaporator, such as temperature sensors, to detect the temperature near the evaporator. The heating tube can include heating tubes arranged at different positions in the oven, and the evaporator can also include evaporators arranged at different positions in the oven. The fan can also include a plurality of fans, such as a convection fan and a cooling fan. In addition, the steaming oven can also include some controller devices of solenoid valves and relays.

[0040] It can be understood that these components of the steaming oven can be divided into 12V powered components and 5V powered components, i.e. the 12V components and the 5V components described in the embodiments of the present application.

[0041] It can be understood that the steaming oven component switch circuit 430 can be a switch controlled by the first master control chip 420 to control the power supply of the corresponding component of the steaming oven 140, for example, to provide power to the component or stop providing power to the component. In this way, the power control group board 120 drives the component.

[0042] It can be understood that the lighting lamp switch circuit 440 can be a switch controlled by the first master control chip 420 to control the power supply of the lighting lamp, for example, to provide power to the lighting lamp or stop providing power to the lighting lamp. Thus, the power control group board 120 realizes the lighting or extinguishing of the lighting lamp.

[0043] The power conversion module 410 includes an AC mains input end 126, a 310V DC output end 411, a 12V DC output end 412 and a 5V DC output end 413.

[0044] The 310V DC output end 411 of the power conversion module 410 is connected with the range DC output end 124 of the power control group board 120.

[0045] The 12V DC output end 412 of the power conversion module 410 is connected with the switch input end 431 of each 12V component switch circuit in the steaming oven component switch circuit 430, and the switch output end 432 of each 12V component switch circuit is respectively connected with the corresponding component DC output end in the steaming oven DC output end 125.

[0046] The 12V DC output end 412 of the power conversion module 410 is also connected with the switch input end 441 of the lighting lamp switch circuit 440, and the switch output end 442 of the lighting lamp switch circuit 440 is connected with the lighting lamp DC output end 128. The lighting lamp switch circuit 440 also comprises the lighting lamp control signal input end 127, so that the switch of the lighting lamp switch circuit 440 can be controlled to be opened or closed through the control signal, and the driving of the lighting lamp is realized.

[0047] The 5V DC output end 413 of the power conversion module 410 is connected with the switch input end 433 of each 5V component switch circuit in the steaming oven component switch circuit 430, and the switch output end 434 of each 5V component switch circuit is connected with the corresponding component DC output end in the steaming oven DC output end 125 respectively.

[0048] Therefore, the power conversion module 410 converts the DC of each different voltage into the corresponding DC output end or flows to the corresponding DC output end through the switch circuit.

[0049] The first main control chip 420 comprises the hood control signal input end 121, the steaming oven control signal input end 122, the hood driving signal output end 123, the 12V component switch control signal output end 421 corresponding to each 12V component switch circuit respectively and the 5V component switch control signal output end 422 corresponding to each 5V component switch circuit respectively. When the first main control chip 420 receives the hood control signal through the hood control signal input end 121, the hood driving signal is provided to the hood driving signal output end 123 and is transmitted to the hood frequency conversion control assembly 130, so that the motor of the hood is driven to work through the hood frequency conversion control assembly 130.

[0050] The 12V component switch control signal output end 421 of the first main control chip 420 is connected with the 12V switch control signal input end 435 of the corresponding 12V component switch circuit respectively, and the 5V component switch control signal output end 422 is connected with the 5V switch control signal input end 436 of the corresponding 5V component switch circuit respectively.

[0051] Therefore, when the first main control chip 420 receives the steaming oven control signal through the steaming oven control signal input end 122, the opening or closing of the 12V component switch circuit and / or the 5V component switch circuit can be controlled, so that the corresponding 12V component or 5V component in the steaming oven is driven to work, and the various cooking functions of the steaming oven are realized.

[0055] It can be appreciated that the switching power supply circuit 414 has the functions of electromagnetic filtering, voltage stepping up, and AC to DC conversion.

[0056] The AC output 417 of the switching power supply circuit 414 is connected to the AC input 418 of the AC / DC conversion circuit 415. The 12V DC output 412 of the AC / DC conversion circuit 415 is connected to the 12V DC input 419 of the DC / DC conversion circuit 416. The AC / DC conversion circuit 415 converts AC to 12V DC. The DC / DC conversion circuit 416 steps down the 12V DC to 5V DC.

[0057] The 12V DC output 412 of the AC / DC conversion circuit 415 is the 12V DC output 412 of the power conversion module 410. The 5V DC output 413 of the DC / DC conversion circuit 416 is the 5V DC output 413 of the power conversion module 410.

[0058] According to the above embodiment, the 220V AC mains is converted to stable 310V DC, 12V DC, and 5V DC by the power conversion module 410, so that the power control group board 120 can provide appropriate DC to each component in the smoke machine and the steam oven, and the smoke machine and the steam oven can work stably.

[0059] In an embodiment, the 5V component switching circuit includes various types of sensor switching circuits. For example, temperature sensors, pressure sensors, flow sensors, etc. These sensor devices are powered by 5V current.

[0063] The power control group board 120 provides power to the water pump or stops providing power to the water pump by opening and closing the water pump switching circuit, so that the power control group board 120 can control whether the water pump in the steam oven works.

[0064] The power control group board 120 provides power to the heat dissipation fan or stops providing power to the heat dissipation fan by opening and closing the heat dissipation fan switching circuit, so that the power control group board 120 can control whether the heat dissipation fan in the steam oven works. Of course, if there are multiple heat dissipation fans, there can also be multiple heat dissipation fan switching circuits, each corresponding to a heat dissipation fan.

[0065] The power control group board 120 provides power to the heat dissipation fan or stops providing power to the heat dissipation fan by opening and closing the heat dissipation fan switching circuit, so that the power control group board 120 can control whether the heat dissipation fan in the steam oven works. Of course, if there are multiple heat dissipation fans, there can also be multiple heat dissipation fan switching circuits, each corresponding to a heat dissipation fan.

[0066] According to the above embodiment, the power control group board 120 can drive some switching circuits to drive the corresponding components in the steam oven to work or control them to stop working.

[0068] It can be understood that the detection result output ends of these detection circuits are connected to the detection result input end of the first main control chip 420. In this way, the first main control chip 420 can receive these detection results and control some components of the steam oven according to the detection results. For example, control some components to work or not to work.

The second master control chip 620 is configured to generate a corresponding gear control signal based on the gear information in the range hood drive signal provided by the range hood drive signal input end 132, and provide the gear control signal to the gear control signal output end 621. The intelligent power module 610 is configured to convert the range hood power DC into the motor power DC corresponding to the gear based on the gear control signal provided by the gear control signal input end 611, and provide the motor power DC to the motor DC output end 133.

[0073] For example, the intelligent power module 610 can be an IMP module.

[0074] For example, the frequency conversion control board 130 of the range hood can further include a voltage detection circuit, a current detection circuit, and a power-on indication circuit. The voltage detection circuit is configured to detect the voltage of the range hood DC input end 131 of the intelligent power module 610 and the voltage of the motor DC output end 133. The current detection circuit is configured to detect the current of the range hood DC input end 131 of the intelligent power module 610 and the current of the motor DC output end 133. In this way, the voltage detection circuit and the current detection circuit provide the detection results to the second master control chip 620, and the second master control chip 620 adjusts the operation of the intelligent power module 610 according to the detection results, so that the intelligent power module 610 outputs stable and appropriate motor power DC to the motor, achieving the effect of smooth operation of the motor.

[0075] When the second master control chip 620 provides the motor power DC to the motor through the motor DC output end 133, the second master control chip 620 controls the power-on indication circuit to output a power-on indication signal. When the motor DC output end 133 of the second master control chip 620 stops providing the motor power DC to the motor, the second master control chip 620 controls the power-on indication circuit to output a power-off indication signal.

[0076] ​According to the above-mentioned embodiment, the driving signal and the appropriate direct current are transmitted to the range hood variable frequency control panel 130 through the display control group panel 110 and the power supply control group panel 120, and the range hood variable frequency control panel 130 converts the received direct current into the motor power supply direct current corresponding to the gear according to the gear signal in the driving signal, and then provides the range hood motor.
