The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. On the contrary, they are merely examples consistent with some aspects of the present invention detailed in the appended claims.
[0026] Please refer to Figure 1 and Figure 2 On the one hand, the present invention provides a self-powered system for a cooking robot, including a cooking module 1. The cooking module 1 includes a furnace 11. A burner 12 for heating the bottom of the furnace 11 is provided at the bottom of the furnace 11. A cookware 13 is provided at the top of the furnace 11. A stirring assembly 14 (not shown in the figure) is provided on one side of the cookware 13. The self-powered system further includes an oil supply module 2, a water supply module 3, a power supply module 4, and a central controller 5. The oil supply module 2 is connected to the burner 12 for supplying oil to the burner 12. The furnace 11 includes a first cavity 111 and a second cavity 112 provided on the outer periphery of the first cavity 111. A circulating water jacket 113 is provided between the first cavity 111 and the second cavity 112. The water supply module 3 is connected to the circulating water jacket 113 for supplying water into the circulating water jacket 113. The power supply module 4 includes a thermoelectric generator 41, a rectifier 42, an inverter 43, and a storage battery 44. The thermoelectric generator 41 is located between the first cavity 111 of the furnace 11 and the circulating water jacket 113. The thermoelectric generator 41 is connected to the rectifier 42. The rectifier 42 is connected to the inverter 43. The inverter 43 is respectively connected to the storage battery 44 and the stirring assembly 14 for supplying the self-generated electric power to the storage battery 44 and the stirring assembly 14.
[0027] The stirring assembly 14, the oil supply module 2, the water supply module 3, the thermoelectric generator 41, and the inverter 43 are all connected to the central controller 5.
[0028] Specifically, the inner thermal grease of the thermoelectric power generation unit 41 is in close contact with the outer wall of the first cavity 111, and the low-temperature part on the outside is in close contact with the circulating water jacket 113. A temperature difference is formed between the high-temperature first cavity 111 and the low-temperature circulating water jacket 113, so that the thermoelectric power generation unit 41 can generate electric energy.
[0029] Both the first cavity 111 and the second cavity 112 are made of heat-resistant steel to withstand the long-term erosion of high-temperature flames.
[0030] In this embodiment, the fuel supply module 2 includes a fuel tank 21 and a fuel pump 22. One end of the fuel pump 22 is connected to the fuel tank 21, and the other end is connected to the burner 12 through a first pipeline. A first solenoid valve 23 and a first flow sensor 24, both connected to the central controller 5, are provided on the first pipeline.
[0031] Specifically, the first pipeline is made of a metal pipe that is pressure-resistant and corrosion-resistant, with firm connections and the ability to withstand high pressures and temperatures. When connecting, appropriate joints and seals need to be used to ensure that the pipeline connections are tight and there are no leaks.
[0032] In this embodiment, the water supply module 3 includes a water tank 31 and a water pump 32. One end of the water pump 32 is connected to the water tank 31, and the other end is connected to the circulating water jacket 113 through a second pipeline. A second solenoid valve 33 and a second flow sensor 34, both connected to the central controller 5, are provided on the second pipeline. A first temperature sensor 35 for detecting the water temperature inside it is provided on the water tank 31, and the first temperature sensor 35 is connected to the central controller 5.
[0033] Specifically, the central controller 5 controls the switch of the water pump 32, receives the water temperature data in the water tank 31 sent by the first temperature sensor 35, and also receives the flow data of the second pipeline sent by the second flow sensor 34. In addition, the central controller 5 controls the water flow rate of the second pipeline by adjusting the switch of the second solenoid valve 33.
[0034] Further, a second temperature sensor for detecting its temperature is also provided on the first cavity 111. The second temperature sensor is connected to the central controller 5 and transmits the heating temperature inside the first cavity 111 to the central controller.
[0035] Further, a third temperature sensor (not shown in the figure) for detecting the water temperature inside it is provided in the circulating water jacket 113. The third temperature sensor is connected to the central controller 5 and transmits the water temperature in the circulating water jacket 113 to the central controller 5.
[0036] Further, the power supply module 4 further includes a DC voltage stabilizer 45. The input end of the DC voltage stabilizer 45 is connected to the output end of the rectifier 42, and the output end of the DC voltage stabilizer 45 is connected to the input end of the inverter 43. Since different heating gears are used in different stages of the cooking process, the temperature in the first cavity 111 will fluctuate, resulting in fluctuations in the generated current and voltage. Therefore, a DC voltage stabilizer 45 is installed after the rectifier 42 to ensure stable voltage and current. At the same time, the inverter 43 can convert the DC voltage of the DC voltage stabilizer 45 into 220V alternating current for supplying other loads, such as the stirring assembly 14.
[0037] Further, the thermoelectric power generation group 41 includes a plurality of power generation rings formed by connecting thermoelectric power generation chips 411 in series. The plurality of power generation rings are connected in parallel. The high-temperature side of each thermoelectric power generation chip 411 is in contact with the first cavity 111, and the low-temperature side is in contact with the circulating water jacket 113. It should be noted that the pasting method of the thermoelectric power generation chips 411 will change with the structure of the first cavity 111. Due to the size and power generation characteristics of the thermoelectric power generation chips, the thermoelectric power generation chips 411 need to be connected in series and parallel in a certain structure so that the output power reaches the 220v conventional power consumption level. The connection structure of the power generation chips is shown in Figure ~.
[0038] Further, an annular heat sink 15 is provided on the outer peripheral surface of the second cavity 112.
[0039] The specific process of this system in practical application is as follows:
[0040] First, the storage battery 44 provides direct current to start the central controller 5 and the fuel pump 22, complete the ignition of the burner 12 to heat the first cavity 111 in the furnace 11, and at the same time start the water pump 32 to inject water into the circulating water jacket 113. After the burner 12 is ignited, the temperature in the first cavity 111 quickly rises above 300 degrees Celsius. At this time, the circulating water jacket 113 is filled with cold water, and a temperature difference is formed between the inside and outside of the thermoelectric power generation group 41. When the temperature difference is greater than 60 degrees Celsius, the central controller 5 starts the thermoelectric power generation group 41 to generate electricity. When the electric quantity reaches a certain intensity, after rectification and inversion, it can be used to supply power to the stirring assembly 14, water pump 32, fuel pump 22, central controller 5 and other loads that require electricity in the cooking robot. The excess electricity charges the storage battery 44 to keep the storage battery 44 fully charged.
[0041] The control process of the self-powered system for a cooking robot provided by the embodiment of the present invention is as follows:
[0042] Step 1: The second temperature sensor and the third temperature sensor transmit the detected temperature information to the central controller 5, and then the central controller 5 can obtain the temperature difference between the first cavity 111 and the circulating water jacket 113;
[0043] Step 2: When the temperature difference in Step 1 is greater than 60°C, the central controller 5 starts the thermoelectric power generation unit 41 to generate electricity. Otherwise, the temperature difference is adjusted according to a preset strategy to meet the requirements for power generation.
[0044] Step 3: After the thermoelectric power generation unit 41 generates electricity, the central controller 5 manages and distributes the self-generated electricity.
[0045] Step 4: When the cooking robot requires different amounts of heat at different cooking stages, the central controller 5 adjusts the switch of the first solenoid valve 23 according to the data detected by the first flow sensor 24 (i.e., the amount of oil flowing into the burner), thereby adjusting the temperature of the first cavity 111, and at the same time adjusts the temperature difference according to the preset strategy in Step 2.
[0046] Step 5: When the stirring component 14 does not need to operate during the cooking process, the thermoelectric power generation unit 41 is controlled to operate by the central controller 5 according to the electricity required by the system, or the temperature difference is adjusted according to the preset strategy in Step 2 to maintain an appropriate temperature difference.
[0047] Among them, in Step 2, the preset strategy includes: determining the set temperature in the circulating water jacket 113 according to the temperature of the first cavity 111 and the temperature difference required by the current thermoelectric power generation unit 41, and through the data detected by the first temperature sensor 35, the third temperature sensor, and the second flow sensor 34 respectively, the central controller 5 then adjusts the switch of the second solenoid valve 33 (i.e., adjusts the size of the water flow) so that the temperature in the circulating water jacket 113 reaches the set temperature.
[0048] In Step 3, the central controller 5 manages and distributes the self-generated electricity, including supplying the self-generated electricity to the water pump 32, the fuel pump 22, the central controller 5, and the stirring component 14 respectively. When there is still surplus electricity after the power supply is completed, the surplus electricity is charged into the storage battery 44.
[0049] In Step 4, for example, in the stir-frying or wok-frying stage, a high flame intensity is required, that is, the temperature of the first cavity 111 becomes higher. The temperature difference is adjusted according to the preset strategy in Step 2 to ensure the relative stability of the thermoelectric power generation current and voltage. For example, in order to achieve energy conservation or at the end of the cooking, the combustion flame is turned down, that is, the temperature of the first cavity 111 becomes lower. The temperature difference is adjusted according to the preset strategy in Step 2 to ensure the relative stability of the thermoelectric power generation current and voltage.
[0050] In Step 5, for example, when entering the second half of the cooking or the stewing stage, the stirring component 41 moves intermittently and requires less electrical energy. First, according to the current electricity consumption requirements, the thermoelectric power generation unit 41 is selected to operate. Specifically, the central controller 5 turns off no more than 1 / 2 of the thermoelectric power generation chips.
[0051] The above are only specific embodiments of the present utility model, enabling those skilled in the art to understand or implement the present utility model. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model.
[0052] It should be understood that the present utility model is not limited to the content already described above, and various modifications and changes can be made without departing from its scope. The scope of the present utility model is only limited by the appended claims.
