Description

Technical Field

[0001] This invention relates to the technical field of electric heating devices, and in particular to a fume extraction lifting pot. Background Technology

[0002] Electric hot pots are a common type of cooking appliance. They are convenient and easy to heat up, especially when cooking hot pot at home. Electric hot pots are more convenient to use, and they are also clean and hygienic, without producing the smoke and harmful gases that charcoal heating plates produce. However, using a traditional electric hot pot for cooking or eating hot pot at the family dinner table also has the following drawbacks: 1. When water or soup in an electric hot pot boils, the steam rises and spreads throughout the room, making the room filled with water vapor, especially in the dining room. At the same time, the wiring terminals of decorative lights such as pendant lights and ceiling lights above the dining table are completely covered by water vapor. Over time or after repeated occurrences, the wiring terminals between the light fixture and the power cord are easily damaged, broken, or short-circuited, leading to light fixture failure. It may also cause poor contact at the damaged wiring terminals, resulting in increased current and heat generation, creating a fire hazard. Second, hot pot is a type of food where almost any ingredient can be put into a soup pot and eaten. The smell of boiling broth permeates the room, causing the room to be filled with odors. In relatively enclosed apartments, it takes a long time for the odors to dissipate. At the same time, the surfaces of bedding, curtains, and sofas in the bedroom absorb the corresponding odors.

[0003] Therefore, there is a need for an electric hot pot that can automatically absorb rising steam, smoke, and fumes when used indoors. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a lifting and venting electric hot pot with a lifting and venting function. This hot pot has an external power input wire, and the main body includes a base and a heating module. A soup pot module is mounted on the base and heating module. A lifting module extends upwards and is upright on the outside of the base and heating module. The top of the lifting module is connected to the venting module, and the venting module and soup pot module are positioned correspondingly. When the lifting module retracts, the venting module moves downwards and closes with the soup pot module. A second wire from the lifting and venting main body is connected to a circuit board within the operating platform. The button-operated circuit board is connected to the heating plate in the base and heating module, the motor controlling the lifting and venting of the module, the suction fan, and the LED light circuit. The circuit board controls the operation via button operation. This invention's venting module can automatically lift and vent, absorbing the hot air and fumes emanating from the soup pot, preventing the hot air and fumes from spreading indoors, and lifting the strainer inside the soup pot to clean food residue.

[0015] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0016] like Figures 1-9 As shown, the oil fume lifting pot is an electric hot pot with a lifting oil fume extraction function. The oil fume lifting pot body 100 includes a base and a heating module 200. A soup pot module 300 is provided on the base and the heating module 200. When in use, the heating module 200 heats up and transfers heat energy to the soup pot 27 of the soup pot module 300 and continues to heat it. When cleaning the soup pot 27 during or after a meal, simply start the motor 19 to make the cylindrical lifting rack 6 rise in the through hole of the guide sleeve 271. When the lifting rack 6 rises, it presses against the top of the blind hole in the soup pot handle 29, and at the same time, it can move the soup pot 30 upward to facilitate the cleaning of food residue in stages. A lifting module 400 extending upwards is erected on the outside of the base and heating module 200. The top of the lifting module 400 is connected to the fume extraction module 500. The fume extraction module 500 is positioned in relation to the soup pot module 300. When the lifting module 400 retracts, the fume extraction module 500 moves downwards and covers the soup pot module 300. When the lifting module 400 rises, it drives the fume extraction module 500 to rise synchronously, which can intercept and absorb the steam, smoke and odors floating upwards in the soup pot 27. The second wire 47 of the oil fume extraction lifting pot body 100 is connected to the circuit board 20 inside the operating platform 210. The button-type circuit board 20 is connected to the heating plate 24 in the base and heating module 200, the second motor 191 that controls the lifting module 400 to lift, the air intake fan 45 and the LED light 38 respectively. The operation is controlled by the button operation of the circuit board 20. The oil fume extraction module of this invention can automatically lift and lower, absorb the hot air and oil fumes coming from the soup pot, prevent the hot air and oil fumes from spreading in the room, and lift the soup strainer in the soup pot to achieve the function of cleaning food residue.

[0017] Example 1: like Figure 6 , Figure 7 As shown, the base and heating module 200 include a frame 2, a bottom cover 1 for closure, forming an accommodating cavity, and a motor bracket 3 is fixed in position within the cavity of the frame 2. Motor 19 is fixed on motor bracket 3. The first gear 4 mounted on the rotating shaft of motor 19 achieves linkage function through meshing second gear 5. The second gear 5 meshes with lifting rack 6, so that when the second gear 5 rolls, the corresponding meshing lifting rack 6 moves axially, achieving the lifting displacement function of the cylindrical lifting rack 6 mounted on rack mounting bracket 8. The soup pot module 300 includes a soup pot 27. The lower end face of the guide sleeve 271 with a through hole is fixedly connected to the bottom of the soup pot 27. The height of the guide sleeve 271 is slightly lower than the height of the soup pot 27. The outer circumference of the guide sleeve 271 in the middle and the inner cavity of the soup pot 27 form a closed food placement area. The through hole in the guide sleeve 271 is connected to the through hole at the bottom of the soup pot 27 and to the outside. The lower end of the soup filter pot 30 is provided with a soup filter pot handle 29. The blind hole in the soup filter pot handle 29 is fitted downward on the outer circumference of the guide sleeve 271, so that the soup filter pot 30 is inserted into the soup pot 27 in a sinking manner. Decorative mesh 1 33 and decorative mesh 2 35 are successively installed in a sinking manner on the upper end of the soup filter pot 30. The through holes in the center of the soup filter pot 30, decorative mesh 1 33 and decorative mesh 2 35 are all sleeved with the sleeve-shaped soup filter pot handle 29. The cylindrical lifting rack 6 can move up and down within the through hole of the guide sleeve 271. When the lifting rack 6 rises, it presses against the top of the blind hole inside the handle 29 of the soup filter pot, and simultaneously moves the soup filter pot 30 up and down. When the lifting rack 6 rises, it presses against the top of the blind hole inside the handle 29 of the soup filter pot, and simultaneously moves the soup filter pot 30 upward to lift it up, which is convenient for cleaning food residue in stages.

[0018] Example 2: like Figure 6 , Figure 7 As shown, the lifting module 400 includes a motor 2 191 with a downward rotating shaft mounting a fourth gear 16, a second rack 18, and the lower ends of the screw 2 23 are mounted and connected to the rack and screw mounting bracket 12. The lower end of the screw 2 23 is connected and mounted a third gear 10. The third gear 10 meshes with the fourth gear 16, so that when the motor 2 191 rotates, it synchronously drives the screw 2 23 to rotate. The soup pot 27 has an upright lower lifting shell 28 on one side of its outer circumference. The upper end of the lower lifting shell 28 is provided with a cap-type screw fixing plate 31. The second rack 18 enters the inner cavity of the lower lifting shell 28 and slides therewith. The straight teeth evenly distributed on the outer circumference of the second rack 18 are inserted into and mesh with the straight teeth in the inner cavity of the lower lifting shell 28. The upper end of the second screw 23 extends out of the inner cavity of the lower lifting shell 28 and out of the upper end face of the screw fixing plate 31. A small gear is installed on the shaft of the second screw 23 that extends out of the upper end face of the screw fixing plate 31. The bottom of the middle section lifting shell 37 contacts the upper end of the lower lifting shell 28 and hides the screw fixing plate 31 inside. The lower end of the upper section lifting shell 40 is fixed with a nut plate 39. The third screw 34 is screwed into the screw hole of the nut plate 39. The lower end of the third screw 34 is provided with a fifth gear 32. The fifth gear 32 meshes with the small gear connected to the upper end of the second screw 23. When motor 2191 rotates, it synchronously drives screw 223 to rotate, which in turn drives the small gear at the upper end of screw 223 to rotate. The fifth gear 32, which meshes with the small gear, drives screw 34 to rotate circumferentially. The rotating screw 34 drives the upper section lifting housing 40, which is integrated with the fixed nut plate 39, to move up and down along the inner cavity of the middle section lifting housing 37, so that the fume extraction module 500 installed at the upper end of the upper section lifting housing 40 can be raised and lowered.

[0019] Example 3: like Figure 6 , Figure 7 As shown, the lower end of the upper lifting connecting plate 43 in the fume extraction module 500 is connected to the upper end of the upper lifting housing 40, and the upper end is connected to the lower cover 44 of the upper connecting plate. The lower cover 44 of the upper connecting plate is a right-angled body that extends inward. An air intake fan base 42 is provided at the inward extension position. An air intake fan 45 is installed on the air intake fan base 42. The air intake fan 45, which works in the air intake mode from bottom to top, is aligned with the center line of the soup pot 27 and can directly intercept and suck in the steam, odors, and oil fumes floating upward in the lower soup pot 27. The upper end of the suction fan 45 is provided with a fan cover 48, which contains a filter sponge 50 and a filter sponge cover 51, and the positions are constrained and fixed. The suction fan 45 filters and absorbs the steam, odor and oil fumes. In application, it can be removed for cleaning or replaced according to the specific degree of pollution, so that the oil fume extraction module 500 can always maintain the normal level of steam or oil fume absorption and storage. In practice, when the filter sponge 50 is kept within the allowable cleanliness level, the oil fumes and dirt absorbed and fixed will not drip downwards. Furthermore, the air intake fan 45 at the bottom provides a continuous upward airflow, further preventing the possibility and potential danger of oil fumes and dirt dripping downwards.

[0020] like Figure 6 As shown, a heat-insulating mica component 13 is embedded on the upper surface of the heating plate base 11. In practice, it is located in the recessed inner cavity in the middle of the heating plate base 11. The heat-insulating mica component 13 can prevent the heat energy generated by the heating plate 24 from spreading downward and escaping through conduction, thereby reducing the temperature rise of the dining environment.

[0021] like Figure 7 As shown, motor 2191 is connected to power supply via wire 17. Threaded power cable 25 is laid out upwards along the inner cavity of the lower lifting housing 28, the inner cavity of the middle lifting housing 37, and the inner cavity of the upper lifting connecting plate 43, and is connected to the air intake fan 45 and LED light 38. All circuit-related work commands are controlled and executed by the button circuit board 20 on the operating platform 210.

[0022] The oil fume extraction lifting pot body 100 of this technical solution can automatically lift and lower to absorb the hot air and oil fumes rising from the soup pot, preventing the hot air and oil fumes from spreading indoors, and also lift the soup strainer inside the soup pot to clean up food residue.

[0023] In practice, to meet different practical application needs, the simplified structure of the 100 technical solution for the fume extraction lifting pot body is as follows: Figure 10 As shown, the base and heating module 200 are equipped with a water collection tray 901. The soup pot module 300 has an upward-extending flue gas inlet pipe 902 at the middle of the bottom of the soup pot 27. The flue gas inlet pipe 902 is equipped with a flue gas flow channel 905. The flue gas flow channel 905 is closed at the top and open at the bottom. The flue gas inlet holes 903 are evenly distributed on the wall of the flue gas inlet pipe 902. The flue gas inlet holes 903 are inclined holes that slope upward from the outside to the inside. The flue gas inlet holes 903 and the flue gas flow channel 905 are connected through each other. The hot steam or flue gas rising upward in the soup pot 27 can enter the flue gas flow channel 905 through the flue gas inlet holes 903, cool and liquefy, and flow downward and drip into the water collection tray 901. A simplified version of the technical solution for the oil fume extraction lifting pot body 100, as shown in section two. Figure 11 As shown, the base and heating module 200 are equipped with a water collection tray 901. The soup pot module 300 has an upward-extending flue gas inlet pipe 902 at the middle of the bottom of the soup pot 27. The upper end of the flue gas inlet pipe 902 is equipped with a flue gas collection block 904. The upper end of the flue gas flow channel 905 in the flue gas inlet pipe 902 is connected to the inner cavity of the flue gas collection block 904, and the lower end of the opening is open. The lower end face and the circumferential wall of the flue gas collection block 904 are evenly distributed with flue gas inlet holes 903. The inner end opening of the flue gas inlet hole 903 is connected to the inner cavity of the flue gas collection block 904. The hot steam or flue gas rising upward in the soup pot 27 can enter the flue gas flow channel 905 through the flue gas inlet holes 903 evenly distributed on the lower end face and the circumferential wall of the flue gas collection block 904, cool and liquefy, and flow downward and drip into the water collection tray 901. For example, 10, Figure 11 The simplified versions of Structure 1 and Structure 2 are passive absorption systems that absorb steam and fumes rising from the top of the soup pot, resulting in lower production costs.

[0024] The advantages of this technical solution in practical applications include, but are not limited to, the following: 1. For example Figure 8 , Figure 9 As shown, when the base of the oil fume extraction lifting pot body 100 and the heating module 200 start heating, the lifting module 400 is lowered and the LED light holder 41 covers the rim of the soup pot 27 to prevent the heat inside the soup pot 27 from overflowing. It has good heat preservation and after cleaning, the volume is reduced, making it easy to store and taking up less space. 2. The motor 19 of the soup pot module 300 drives the lifting rack 6 to lift the strainer 30, decorative mesh 1 33, and decorative mesh 2 35 inside the soup pot 27 from bottom to top. At the same time, it lifts up the cooked ingredients in the soup pot 27 and drains the soup, which makes it easier to take out when eating hot pot. It eliminates the hygiene problem of chopsticks being washed in hot pot soup, and makes subsequent cleaning and washing convenient. 3. The fume extraction module 500 of the oil fume extraction lifting pot body 100 can be electrically raised to absorb the hot air and oil fumes coming from the pot, preventing the hot air and oil fumes from spreading indoors, and absorbing and collecting the steam, odors and oil fumes inside, and using the filter sponge 50 to collect them centrally.

[0025] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
