DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0019] Embodiment 1 See also Figure 1 - Figure 8 As shown, the present invention is an energy storage power supply type large cooker based on the principle of semiconductor temperature difference power generation, 1. It includes a cooker frame 1, a flue 4 is fixedly installed on one side of the cooker frame 1, and the flue 4 includes a temperature difference power generation module. The temperature difference power generation module includes a small-aperture fin 5 and a large-aperture fin 8 fixedly installed on the inner wall of the flue 4. A plurality of fins with apertures ranging from large to small are arranged in the flue 4. The temperature difference power generation sheet 11 is fixedly installed on both sides of the flue 4. The temperature difference power generation module is installed on the vertical flue 4. The temperature difference power generation sheet 11 is tightly attached to the outer side of the flue 4 by using silicone grease, a material with good thermal conductivity. At the same time, when designing the flue, the thickness of the front and rear walls gradually increases with the direction of the flue gas, and there is a difference of 5mm between the bottom and the top, so that the flue gas contacts the front and rear walls with a larger area during the flow. There are 20 temperature difference power generation sheets 11 on the front and rear sides of the flue 4, which are arranged in 4 rows and 5 columns. The same row on the front and rear sides is connected in series, and the rows are connected in parallel. By adjusting the external resistor, the maximum power generation power is achieved.
[0020] During the operation of the large pot stove, the flue gas transfers a large amount of heat through the flue 4 to the large-aperture fins 8 on the inner wall of the flue 4. The fins transfer the heat to the hot end of the thermoelectric generator 11 and the cooling water tank 2 close to the cold end of the thermoelectric generator 11, which is filled with circulating coolant, so that the thermoelectric generator generates electricity, and then is connected in series with the DC blower 10 to supply power for it. Finally, the flue gas flows through the small-aperture fins 5 of the component and then flows out of the flue 4. The flue gas flows through four fins in the flue 4. The aperture sizes on the fins are 40mm, 18mm, 10mm, and 6mm from bottom to top. The number of holes increases successively, and the heat transfer effect is better. When the flue gas temperature is low at high altitudes, a high power generation capacity can still be maintained. While ensuring that there is a high temperature difference at both ends of the thermoelectric generator 11, sufficient electricity is output to meet the power consumption of the DC blower 10 of the large pot stove. A cleaning component 9 is provided in the flue 4; The cleaning assembly 9 includes a reciprocating screw 94 rotatably mounted on the inner wall of one end of the stove frame 1 near the small-aperture fin 5, a slider 95 is threadedly installed on the reciprocating screw 94, a heat shield 92 is fixedly installed on one side of the flue 4, the heat shield 92 plays a role in blocking heat, a motor 93 is fixedly installed on the side of the heat shield 92 away from the flue 4, the motor 93 drives the reciprocating screw 94 to rotate, a rectangular through hole 99 is opened on the small-aperture fin 5 and the large-aperture fin 8, an extension rod 96 is fixedly installed on the side of the slider 95 near the small-aperture fin 5, and a fixed extension rod 96 is installed on the extension rod 96 There is a cleaning plate 97, and the extension rod 96 drives the cleaning plate 97 to reciprocate on the inner wall of the flue 4. A baffle 91 is fixedly installed on the inner wall of the flue 4 close to one end of the reciprocating screw 94, and a scraper 98 is fixedly installed on the end of the extension rod 96 away from the slider 95. The scraper 98 is convenient for cleaning the dust accumulated on the large-aperture fin 8. There are multiple cleaning plates 97, which can not only clean the dust on the inner wall of the flue 4, but also clean the auxiliary dust on the fins, thereby avoiding the blockage of the fins as much as possible, which is beneficial to improving the thermal conductivity of the flue 4 and reducing heat loss.
[0021] The output end of the motor 93 slides through the heat blocking block 92 and the flue 4 and is fixedly installed on the reciprocating screw 94. The side of the slider 95 away from the small-aperture fin 5 is tightly fitted with the side of the baffle 91, and the baffle 91 plays the role of limiting the slider 95. The extension rod 96 slides through and is installed in the rectangular through hole 99. A mounting plate 910 is fixedly installed on the inner wall of the flue 4 near the small-aperture fin 5. A spring 911 is fixedly installed on the side of the mounting plate 910 near the small-aperture fin 5. The spring 911 is convenient for driving the knocking ball 912 to reciprocate elastically. A knocking ball 912 is fixedly installed on the end of the spring 911 away from the mounting plate 910. The knocking ball 912 has a certain gravity, which plays the role of knocking on the large-aperture fin 8 to vibrate and clean the dust, which is beneficial to improving the thermal conductivity of the flue 4.
[0022] Embodiment 2 See also Figure 1 - Figure 3As shown, on the basis of the first embodiment, a cooling circulation module is arranged on the flue 4, and the cooling circulation module comprises a water tank 12 fixedly mounted on both sides of the flue 4, a pressure relief valve 31 is fixedly mounted on the position of the water tank 12 near one end of the small-aperture fin 5, a heat insulation cotton is arranged between the water tank 12 and the flue 4, a first water outlet 3 is provided at the position of the water tank 12 far from one end of the pressure relief valve 31, a water inlet 7 is provided on the side of the water tank 12 near the pressure relief valve 31, a cooling water tank 2 is fixedly mounted on the side of the temperature difference power generation sheet 11 far from the flue 4, and there is also coolant in the cooling water tank 2, a second water outlet 6 is provided on the side of the cooling water tank 2 near the small-aperture fin 5, and the cooling water tank 2 is far from the flue 4. A connecting pipe is installed between the end away from the second water outlet 6 and the first water outlet 3. The water tank 12 on the side of the cooling water tank 2 and the flue 4 is filled with coolant. After absorbing the heat of the flue 4, the coolant in the cooling water tank 2 increases in temperature and decreases in density. The coolant generates buoyancy due to the change in density and rises naturally in the cooling water tank 2. At the same time, since the first water outlet 3 of the water tank 12 is higher than the water inlet of the cooling water tank 2, according to the connecting vessel principle, the coolant flowing out of the water tank 12 will enter the cooling water tank 2. In the cooling water tank 2, as the water is further heated in the direction of the flue gas, a density gradient will be established, thereby driving the overall coolant to circulate naturally by convection. There are pressure relief valves 31 on the top of the water tanks on both sides. When the pressure of the water tank is too high, the paddle inside the pressure relief valve 31 will open and then discharge the gas inside.
[0023] The coolant enters from the upper water inlet 7 of the water tank 12, flows out from the lower first water outlet 3, and enters the lower water inlet of the cooling water tank 2 through the connecting pipe. After passing through the temperature difference power generation plate 11, the coolant in the cooling water tank 2 is discharged outward through the upper second water outlet 6. After the temperature difference power generation plate 11 is cooled and the flue 4 is directly heated, the coolant in the cooling water tank 2 naturally rises due to the change in density. At the same time, due to the presence of the thermal insulation cotton, the coolant in the water tank 12 will be cooled. The cooled coolant will fall due to the increase in density. Since the first water outlet 3 of the water tank 12 is higher than the water inlet of the cooling water tank 2, the coolant falls according to the connecting vessel principle.
[0024] Embodiment 3 See also Figure 7 and Figure 3As shown, on the basis of embodiment 1 and embodiment 2, a fixing module is arranged on the flue 4, and the fixing module includes a first front clamping plate 19 and a first rear clamping plate 20. The first front clamping plate 19 and the first rear clamping plate 20 are respectively installed on the outer surface of the cooling water tank 2. The first front clamping plate 19 and the first rear clamping plate 20 are connected by a first bolt 18 to ensure that the thermoelectric power generation sheet 11 is in close contact with the outer side of the flue 4, thereby increasing the temperature of the hot end of the thermoelectric power generation sheet 11, ensuring that the thermoelectric power generation sheet 11 is in close contact with the cooling water tank 2, and reducing the temperature of the cold end of the thermoelectric power generation sheet 11, which is beneficial to improving the thermal energy utilization rate of the device.
[0025] Embodiment 4 See also Figure 8 and Figure 1 As shown, on the basis of the first, second and third embodiments, a power conversion module is provided in the stove frame 1, the power conversion module comprises a battery 13 installed in the stove frame 1, a power detector 14 is electrically connected to the temperature difference power generation sheet 11, a DC blower 10 is fixedly installed at the bottom of the stove frame 1, and the battery 13 is electrically connected to the DC blower 10. When the large stove is started, due to the low power of the temperature difference power generation sheet 11, the second control switch 16 is closed and the first control switch 15 is opened. At this time, the battery 13 directly supplies power to the DC blower. The fan 10 is powered, and when the temperature in the large stove flue 4 gradually rises, the power of the thermoelectric power generation sheet 11 gradually reaches the power required by the DC blower 10, at this time, the second control switch 16 is disconnected, and the first control switch 15 is closed, and the thermoelectric power generation sheet 11 directly supplies power to the DC blower 10; after the DC blower 10 finishes working, the single-pole double-throw switch 17 is turned to the other side to connect the charging circuit. At this time, the thermoelectric power generation sheet 11 uses the waste heat in the flue 4 to start charging the battery 13 to make up for the power loss, thereby achieving the purpose of saving electricity.
[0026] The working principle of the present invention is as follows: when the large pot stove is started, due to the low power of the thermoelectric power generation sheet 11, the second control switch 16 is closed and the first control switch 15 is disconnected. At this time, the battery 13 directly supplies power to the DC blower 10. When the temperature in the flue 4 of the large pot stove gradually rises, the flue gas transfers a large amount of heat through the flue 4 to the large-aperture fins 8 on the inner wall of the flue 4. The fins transfer the heat to the hot end of the thermoelectric power generation sheet 11 and the cooling water tank 2 close to the cold end of the thermoelectric power generation sheet 11 is filled with circulating coolant, so that the thermoelectric power generation sheet generates electricity, and then is connected in series with the DC blower 10 to supply power to it. Finally, the flue gas flows through the small-aperture fins 5 of the component and then flows out of the flue 4. At the same time, the power of the thermoelectric power generation sheet 11 gradually reaches the power required by the DC blower 10. At this time, the second control switch 16 is disconnected and the first control switch 15 is closed. The thermoelectric power generation sheet 11 directly supplies power to the DC blower 10. After the DC blower 10 finishes working, the single The knife double throw switch 17 is turned to the other side to connect the charging circuit. At this time, the temperature difference power generation sheet 11 uses the residual heat in the flue 4 to start charging the battery 13. When the flue 4 needs to be cleaned, the motor 93 is first started to make the output end of the motor 93 drive the reciprocating screw 94 to rotate, and at the same time, the reciprocating screw 94 drives the slider 95 to reciprocate on the baffle 91, and at the same time, the slider 95 drives the extension rod 96 to slide in the rectangular through hole 99, and at the same time, the extension rod 96 drives the cleaning plate 97 scrapes the dust back and forth on the inner wall of the flue 4, and at the same time, the extension rod 96 drives the scraper 98 to scrape on the large-aperture fin 8, and at the same time, the scraper 98 pushes the knocking ball 912, and at the same time, the knocking ball 912 pulls the spring 911, so that the spring 911 is in a stretched state. After the scraper 98 moves past the knocking ball 912, the elastic restoring force of the spring 911 drives the knocking ball 912 to hit the large-aperture fin 8, which is convenient for shaking off the dust scraped off by the scraper 98, thereby facilitating vibration dust removal.
[0027] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
