Description

[0002] As users' cooking needs improve, multi-functional cooking appliances are becoming increasingly popular among consumers. Typically, multi-functional cooking appliances include steam ovens or integrated steam ovens / grills. Among them, dual-cavity steam ovens, with their two cooking cavities and high degree of integration, are gradually becoming the mainstream product in the integrated stove industry.

[0003] Conventional single-cavity steam ovens typically operate at 2100W / 10A or 3300W / 16A. Household appliances generally draw 16A and have a maximum power of 3500W. Considering electrical safety and power consumption from additional functional modules, the heating power for steaming and baking usually does not exceed 3000W. Dual-cavity steam ovens have both cooking cavities with steaming and baking functions, and their total power generally exceeds 5000W. To ensure electrical safety, most manufacturers either functionally separate the two cooking cavities (e.g., one cavity for baking and the other for steaming) or reduce the heating power to achieve simultaneous cooking in both cavities.

[0026] Example 1

[0027] Figure 1 This is a schematic diagram of a dual-cavity cooking control device according to Embodiment 1 of the present invention. This embodiment is applicable to cooking equipment that controls dual-cavity high-power cooking through a single power supply motherboard. In this embodiment, the cooking equipment is equipped with two power connectors to connect to two independent power supplies. The power supplies output alternating current (AC), for example, AC with a rated voltage of 220V.

[0028] See Figure 1 As shown, the dual-cavity cooking control device 1 of this application includes: a main control module 110, a detection module 120, a first power supply circuit 130, and a second power supply circuit 140, all disposed on the same power control board 100.

[0029] The first power supply circuit 130 is connected to a first power supply (such as a household two-prong or three-prong socket) via a first power connector 10 (such as a two-prong or three-prong plug) to supply power to at least a portion of the load in the first cooking cavity. In this embodiment, the loads connected to the first power supply circuit include, but are not limited to, high-power AC loads within the first cooking cavity. Typically, high-power AC loads within the first cooking cavity include, but are not limited to, the upper heating element and the lower heating element within the first cooking cavity.

[0030] The second power supply circuit 140 is connected to a second power supply (such as a household two-prong or three-prong socket) via a second power connector 20 (such as a two-prong or three-prong plug) to supply power to at least a portion of the load in the second cooking cavity. In this embodiment, the loads connected to the second power supply circuit include, but are not limited to, high-power AC loads within the second cooking cavity. Typically, high-power AC loads within the second cooking cavity include, but are not limited to, the upper heating element of the second cooking cavity and the lower heating element of the second cooking cavity. In this embodiment, the first power supply and the second power supply independently output AC power (e.g., 220V AC power).

[0031] The detection module 120 is electrically connected to the first power connector 10 and the second power connector 20, respectively, and is used to detect the power-on state of the first power connector 10 and the second power connector 20. Specifically, when the first power connector 10 is connected to the first power supply, the detection module 120 detects that the first power connector 10 is in a powered-on state; when the first power connector 10 is not connected to the first power supply, the detection module 120 detects that the first power connector 10 is in a powered-off state. When the second power connector 20 is connected to the second power supply, the detection module 120 detects that the second power connector 20 is in a powered-on state; when the second power connector 20 is not connected to the second power supply, the detection module 120 detects that the second power connector 20 is in a powered-off state.

[0032] The main control module 110 is connected to the detection module 120 and is used to adjust the operating state of the first power supply circuit 130 and the second power supply circuit 140 according to the power-on state. In some embodiments, the main control module 110 is configured to: control the first power supply circuit 130 to be turned on to supply power to at least a portion of the load in the first cooking cavity when both the first power connector 10 and the second power connector 20 are in a powered-on state; and control both the first power supply circuit 130 and the second power supply circuit 140 to remain disconnected when either the first power connector 10 or the second power connector 20 is in a powered-off state, at which time the circuits of both cooking cavities cannot work. In other embodiments, the main control module 110 is further configured to: control the first power supply circuit 130 to be turned on to supply power to all the load in the first cooking cavity when the first power connector 10 is in a powered-on state, or control the second power supply circuit 140 to be turned on to supply power to all the load in the second cooking cavity when the second power connector 20 is in a powered-on state.

[0033] Specifically, when high-power cooking is required simultaneously in both cavities, the detection module 120 monitors the power-on status of the first power connector 10 and the second power connector 20 in real time. If either the first power connector 10 or the second power connector 20 is de-energized, the main control module 110 controls both the first power supply circuit 130 and the second power supply circuit 140 to disconnect, and the circuit cannot operate. If both the first power connector 10 and the second power connector 20 are energized, the main control module 110 controls the first power supply circuit 130 and the second power supply circuit 140 to connect, supplying power to the electrical loads of the two cooking cavities according to the actual circuit distribution. By setting two power supply circuits to connect different power connectors and electrical loads, the high-power loads of the two cooking cavities are connected to different power sources, enabling simultaneous high-power cooking in both cavities. This ensures that the operating power of a single power supply circuit does not exceed the rated power limit, improving the efficiency and heating effect of dual-cavity cooking and enhancing the user's cooking experience. Integrating dual-cavity power supply control on a single power board saves circuit costs and installation space.

[0034] Optionally, Figure 2 This is a schematic diagram of another dual-cavity cooking control device provided in Embodiment 1 of the present invention. See also... Figure 2 As shown, the power control board also includes a switching power supply module 150 and a DC bus. The input terminal of the switching power supply module 150 is electrically connected to at least one of the first power connector 10 and the second power connector 20, and the output terminal of the switching power supply module 150 is electrically connected to the DC bus to output DC power to the DC load connected to the DC bus. The main control module 110 is also configured to control the switching power supply module 150 to start or stop according to the power-on state of the first power connector 10 and / or the second power connector 20. Optionally, the switching power supply module 150 includes, but is not limited to, an AC-DC voltage converter, a DC-DC boost converter, and a DC-DC buck converter. In this embodiment, the switching power supply module 150 can be used to output a DC voltage of at least one voltage level.

[0035] In this embodiment, the DC load includes at least one of the following: a first door control switch for the first cooking cavity, a second door control switch for the second cooking cavity, a water tank switch, a water level detection unit, a temperature detection unit, a water pump, and a drain pump. The first door control switch controls the opening or closing of the door of the first cooking cavity; the second door control switch controls the opening or closing of the door of the second cooking cavity; the water tank switch controls the opening or closing of the water tank valve of the cooking equipment; the water level detection unit detects the water level in the water tank of the cooking equipment; the temperature detection unit detects the temperature inside the cooking cavity, typically including a first NTC sensor disposed in the first cooking cavity and a second NTC sensor disposed in the second cooking cavity; the drain pump drives the drainage of accumulated water inside the cooking cavity; and the water replenishment pump replenishes the water tank.

[0036] In some embodiments, the main control module 110 is configured to: control the switching power supply module 150 to start when both the first power connector 10 and the second power connector 20 are in a powered-on state, so as to output DC power supply to the DC load connected to the DC bus; and control the switching power supply module 150 to turn off when either the first power connector 10 or the second power connector 20 is in a powered-off state, so as to stop outputting DC power supply to the DC load connected to the DC bus.

[0037] In other embodiments, the input terminal of the switching power supply module 150 is electrically connected to the first power connector 10, and the main control module 110 is configured to control the switching power supply module 150 to start when the cooking device only needs the second power supply circuit 140 to be powered on, so as to output DC power to the DC load connected to the DC bus. Specifically, when both the first power connector 10 and the second power connector 20 are powered on, if both cooking cavities simultaneously activate high-power cooking functions, the main control module 110 controls the first power supply circuit 130, the second power supply circuit 140, and the switching power supply module 150 to all start. The first power supply supplies AC load to the first cooking cavity via the first power supply circuit 130, and simultaneously outputs DC power to the DC load connected to the DC bus via the switching power supply module 150. The second power supply supplies AC load to the second cooking cavity via the second power supply circuit 140. The two power supplies power different high-power heating devices respectively. If only the second cooking cavity is activated, the main control module 110 controls the second power supply circuit 140 and the switching power supply module 150 to start. The first power supply supplies DC power to the DC load connected to the DC bus via the switching power supply module 150, and the second power supply supplies AC load to the second cooking cavity via the second power supply circuit 140. By optimizing the control strategy, simultaneous high-power cooking in both cavities or cooking in a single cooking cavity can be achieved. The cooking functions are diverse, the operation is convenient and flexible, and it is not affected by the power limit, thus improving cooking efficiency.

[0038] Optionally, the main control module 110 is communicatively connected to at least one of the DC loads. The main control module 110 is configured to acquire detection data provided by the DC load and adjust the operating duration of the first power supply circuit 130 and the second power supply circuit 140 based on the detection data. In this embodiment, the detection data provided by the DC load includes, but is not limited to, temperature detection data of the first cooking cavity and temperature detection data of the second cooking cavity provided by the temperature detection unit. Specifically, during the cooking process, the temperature detection unit continuously collects temperature detection data of the first cooking cavity and temperature detection data of the second cooking cavity. The main control module 110 controls the on / off time of the first power supply circuit 130 and the second power supply circuit 140 through a program to control the on / off time of the heating device, thereby achieving precise temperature control inside the two cooking cavities.

[0039] Optionally, Figure 3This is a schematic diagram of a detection module provided in Embodiment 1 of the present invention. See also... Figure 3 As shown, the detection module 120 includes a first light emitting unit 121, a first light detection unit 122, a second light emitting unit 123, and a second light detection unit 124. The first light emitting unit 121 is electrically connected to the first power connector 10 and is used to trigger a first preset light signal (e.g., visible light or infrared light signal) based on a first power-on state of the first power connector 10. The first light detection unit 122 is disposed opposite to the first light emitting unit 121 and is used to detect the first preset light signal and send the corresponding first power-on detection signal to the main control module 110. The second light emitting unit 123 is electrically connected to the second power connector 20 and is used to trigger a second preset light signal based on a second power-on state of the first power connector 10. The second light detection unit 124 is disposed opposite to the second light emitting unit 123 and is used to detect the second preset light signal and send the corresponding second power-on detection signal to the main control module 110.

[0040] In some embodiments, the first light emitting unit 121 and the second light emitting unit 123 are infrared light emitters, and the first light detection unit 122 and the second light detection unit 124 are infrared light receivers. In other embodiments, the first light emitting unit 121 and the second light emitting unit 123 are visible light sources, and the first light detection unit 122 and the second light detection unit 124 are optical couplers. In still other embodiments, the first light emitting unit 121 can be configured as an infrared light emitter, the first light detection unit 122 as an infrared light receiver, the second light emitting unit 123 as a visible light source, and the second light detection unit 124 as an optical coupler, to avoid mutual interference between the detection units of the two power connectors.

[0041] Specifically, the first power connector 10 has a positive power terminal and a negative power terminal. The first end of the first optical emitting unit 121 is electrically connected to the positive power terminal of the first power connector 10, and the second end of the first optical emitting unit 121 is electrically connected to the negative power terminal of the first power connector 10. After the first power connector 10 is successfully connected to the first power supply, the first optical emitting unit 121 emits a first preset optical signal. If the first optical detection unit 122 detects the first preset optical signal, it sets the first power-on detection signal to a high level and sends it to the main control module 110; if the first optical detection unit 122 does not detect the first preset optical signal, it sets the first power-on detection signal to a low level and sends it to the main control module 110. When the first power-on detection signal is a high level signal, the main control module 110 determines that the first power connector 10 is in a powered-on state; when the first power-on detection signal is a low level signal, it determines that the first power connector 10 is in a powered-off state. It should be noted that the connection method and working principle of the second optical emitting unit 123 and the second optical detection unit 124 are the same as those of the first optical emitting unit 121 and the first optical detection unit 122, and the same parts will not be described again. By configuring different types of optical emitting and optical receiving elements, the power connector power-on detection is realized, which is simple in structure and low in cost.

[0042] Optionally, Figure 4 This is a schematic diagram of another dual-cavity cooking control device provided in Embodiment 1 of the present invention. See also... Figure 4 As shown, the first power supply circuit 130 includes a first switch unit 131 and a first AC bus 132, and the second power supply circuit 140 includes a second switch unit 141 and a second AC bus 142. The control terminal of the first switch unit 131 is connected to the main control module 110, the input terminal of the first switch unit 131 is connected to the first power supply via the first power connector 10, and the output terminal of the first switch unit 131 is electrically connected to the first AC bus 132. The control terminal of the second switch unit 141 is connected to the main control module 110, the input terminal of the second switch unit 141 is connected to the second power supply via the second power connector 20, and the output terminal of the second switch unit 141 is electrically connected to the second AC bus 142.

[0043] Optionally, the load of the first AC bus 132 includes at least: a first main heating load and a first oven lamp disposed in the first cooking cavity; the load of the second AC bus 142 includes at least: a second main heating load and a second oven lamp disposed in the second cooking cavity; at least one of the first AC bus and the second AC bus is connected to an auxiliary heating load. The first main heating load includes at least a first upper heating element and a first bottom heating element disposed in the first cooking cavity; the second main heating load includes at least: a second upper heating element and a second bottom heating element disposed in the second cooking cavity. The auxiliary heating load includes, but is not limited to: an evaporator heating element, a cooling fan, and an inner tank heating fan.

[0044] Specifically, after the dual-cavity cooking device is powered on, the detection module 120 detects the power-on status of the first power connector 10 and the second power connector 20 in real time. If either the first power connector 10 or the second power connector 20 is in a de-energized state, the main control module 110 controls the first switch unit 131 and the second switch unit 141 to disconnect, thus disconnecting the first power supply circuit 130 and the second power supply circuit 140, and the circuit cannot work. If both the first power connector 10 and the second power connector 20 are in a powered-on state, the main control module 110 controls the first switch unit 131 and the second switch unit 141 to close, thus connecting the first power supply circuit 130 and the second power supply circuit 140. For example, the first power supply circuit 130 supplies power to the first upper heating element, the first bottom heating element, and the first oven lamp located in the first cooking cavity. The first power supply circuit 130 also supplies power to auxiliary heating loads such as the evaporator heating element, the cooling fan, and the inner liner heating fan. The second power supply circuit 140 supplies power to the second upper heating element, the second bottom heating element, and the second oven lamp located in the second cooking cavity. This separates the power supply to the high-power loads in the two cooking cavities, enabling simultaneous high-power cooking in both cavities. It ensures that the operating power of a single power supply circuit does not exceed the rated power limit, thereby improving the cooking efficiency and heating effect of the two cavities.

[0045] Optionally, see Figure 4 As shown, the dual-cavity cooking control device 1 of this application further includes: an operation panel 160, which is communicatively connected to the main control module 110, and is also electrically connected to at least one of the first power connector 10 and the second power connector 20; the main control module 110 is further configured to: after the operation panel 160 is powered on, respond to the human-machine interaction operation of the operation panel 160 to adjust the working state of the first power supply circuit 130 and / or the second power supply circuit 140.

[0046] Specifically, after the first power supply circuit 130 and the second power supply circuit 140 are connected, the user can perform corresponding function operations through the operation panel 160, such as configuring any cooking cavity to perform steaming or baking functions. After the function is selected, the main control module 110 controls the power supply management of the corresponding power supply circuit by controlling the on / off state of the first switch unit 131 and the second switch unit 141, realizing the function of a single main control board controlling dual power supplies, which is flexible in operation, convenient in use, and improves the user's cooking experience.

Figure 5 As shown, the cooking device of this application includes: a first power connector 10, a second power connector 20, and the aforementioned dual-cavity cooking control device 1; wherein, the first power connector 10 is connected to a first power supply, and the second power connector 20 is connected to a second power supply; the dual-cavity cooking control device 1 is used to detect the power-on status of the first power connector 10 and the second power connector 20, and to manage the power supply to the two cooking cavities of the cooking device according to the power-on status.

[0050] See Figure 5 As shown, the first power supply supplies power to the DC load 510 of the cooking equipment via the first power connector 10. The first power supply also supplies power to the first type of AC load 520 of the first cooking cavity via the first power connector 10. The second power supply supplies power to the second type of AC load 530 of the second cooking cavity via the second power connector 20.
