Description

Technical Field

[0001] This invention relates to the field of integrated cooktop and range hood technology, specifically an integrated cooktop and range hood unit that combines an induction cooker and a range hood. Background Technology

[0002] In modern households and the catering industry, with the improvement of living standards and the diversification of cooking methods, the demand for kitchen appliances, especially integrated range hoods and cooktops, is increasing. These products typically integrate two major functional modules: an induction cooker and a range hood, aiming to provide a dual solution for efficient cooking and fume extraction, and belong to the field of household appliances and kitchen equipment. Among them, the horizontal dual-head induction cooker and range hood integrated unit has become a popular choice in the market because it can simultaneously meet the needs of quickly cooking multiple dishes.

[0003] However, existing horizontal dual-head induction cooker and range hood combo units generally suffer from problems such as low heat dissipation efficiency and poor smoke exhaust. Especially under high-power operation, if the large amount of heat generated by the induction cooker cannot be dissipated in a timely and effective manner, it will not only affect the performance and lifespan of the equipment, but may also cause the kitchen environment temperature to rise, affecting the comfort and safety of the cook. At the same time, the accumulation of smoke inside the range hood and cooktop housing leads to a decrease in smoke exhaust efficiency, and the filter screen relies solely on passively intercepting oil stains, which easily clogs the mesh due to oil buildup, requiring frequent manual disassembly and cleaning. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated induction cooker, range hood, and stove unit to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An integrated induction cooker, range hood, and cooktop unit, comprising: A range hood and stove support box is connected to an exhaust box. An induction cooker heating platform is symmetrically arranged inside the range hood and a number of induction cooker support plates are arranged directly below the induction cooker heating platform. A heat dissipation assembly is used to dissipate heat from the induction cooker's support plate; A smoke exhaust assembly is disposed in the exhaust box and is used to exhaust air from the inside of the range hood carrier box; A filtration assembly, comprising a filter screen and a storage mechanism, wherein the filter screen is used to filter oil and the storage mechanism is used to store the filtered oil. An oil stain self-cleaning component includes a temperature-sensing trigger mechanism, a scraping mechanism, a phase-change air storage mechanism, and a spray cleaning mechanism. The temperature-sensing trigger mechanism drives the scraping mechanism to move along the filter screen according to temperature changes. The scraping mechanism is used to scrape off oil stains attached to the filter screen. The phase-change air storage mechanism is used to compress air using temperature changes. The spray cleaning mechanism is used to spray compressed air to clean the mesh of the filter screen.

When the temperature changes, the bimetallic spiral disk will drive the transmission rod to rotate through the connecting rod. One end of the slider is rotatably connected to the transmission rod, and the slider is slidably connected to the scraper.

[0013] Preferably, the phase change gas storage mechanism includes a piston cylinder, a piston rod, a return spring, a gas cylinder, and a gas tank. The piston cylinder is connected to the piston rod, and the two ends of the piston rod are respectively connected to the piston cylinder and the gas cylinder. The piston cylinder is filled with thermosensitive wax. When the temperature of the piston cylinder rises, the thermosensitive wax melts and expands, pushing the piston rod to move along the gas cylinder. The return spring is used to drive the piston rod to return to its original position. When the piston rod moves along the gas cylinder, it compresses air into the gas tank.

[0014] Preferably, the spray cleaning mechanism includes a pressure relief valve, a mounting plate, and nozzles. The pressure relief valve is connected to the gas tank and is connected to the mounting plate via a pipe. The mounting plate is provided with a plurality of nozzles.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-15 The present invention provides a technical solution: An integrated induction cooker, range hood, and stove unit, as per the instruction manual. Figure 1 As shown, it includes: The range hood and stove support box 1 is used to install the induction cooker heating platform 3. The range hood and stove support box 1 is connected to the exhaust box 2. The induction cooker heating platform 3 is symmetrically arranged in the inner cavity of the range hood and stove support box 1. Several induction cooker support plates 301 are provided directly below the induction cooker heating platform 3. The induction cooker heating platform 3 is provided above each induction cooker support plate 301. Heat dissipation component, used to dissipate heat from the induction cooker support plate 301; The smoke exhaust assembly is installed in the exhaust box 2 and is used to exhaust air from the inside of the range hood carrier box 1. The filter assembly includes a filter screen 4 and a storage mechanism. The filter screen 4 is disposed in the connecting box 10. The filter screen 4 is used to filter oil and the storage mechanism is used to store the filtered oil. The oil stain self-cleaning component includes a temperature-sensing trigger mechanism, a scraping mechanism, a phase change air storage mechanism, and a spray cleaning mechanism. The temperature-sensing trigger mechanism is used to drive the scraping mechanism to move along the filter screen 4 according to the temperature change. The scraping mechanism is used to scrape off the oil stains attached to the filter screen 4. The phase change air storage mechanism is used to compress air by utilizing the temperature change. The spray cleaning mechanism is used to use compressed air to spray and clean the mesh of the filter screen 4.

[0020] An arc-shaped enclosure 5 is provided outside the heat dissipation component to form an exhaust channel. In this embodiment, the arc-shaped enclosure 5 is located outside the heat dissipation fan 7.

[0021] An auxiliary air duct box 6 is provided inside the range hood and stove support box 1. The auxiliary air duct box 6 is used to connect to the box 10.

[0022] The heat dissipation assembly includes a cooling fan 7, heat dissipation fins 8, and a heat dissipation base 9. Each induction cooker support plate 301 is equipped with a cooling fan 7, which is used to dissipate heat and exhaust air from the induction cooker heating platform 3. Each cooling fan 7 is equipped with a heat dissipation fin 8 on one side, which is used for heat conduction and heat dissipation during heat dissipation and exhaust. A heat dissipation base 9 is provided at the bottom of the heat dissipation fin 8, which is used to install the heat dissipation fin 8.

[0023] The exhaust box 2 has a main air duct 201. The smoke exhaust assembly includes a connecting box 10 and a centrifugal fan 11. The connecting box 10 is used to connect the exhaust box 2 and the stove support box 1. The centrifugal fan 11 is located inside the exhaust box 2 and is used to generate negative pressure in the main air duct 201.

[0024] The storage mechanism includes an oil storage tank 12, which is located inside the connecting box 10. The oil storage tank 12 is used to receive the oil filtered out by the filter screen 4.

[0025] The connecting box 10 is provided with a sliding groove, which is used to restrict the movement direction of the scraper 13 so that it can only move along the direction of the sliding groove. The scraping mechanism includes the scraper 13, which is slidably connected to the sliding groove. The scraper 13 is magnetically attracted to the filter screen 4. The temperature-sensing triggering mechanism is used to drive the scraper 13 to reciprocate along the sliding groove.

[0026] The temperature-sensing trigger mechanism includes a bimetallic spiral disk 14, a connecting rod 15, a transmission rod 16, and a slider 17. In this embodiment, the bimetallic spiral disk 14 is made of a nickel-titanium alloy and brass composite. The bimetallic spiral disk 14 is disposed in the connecting box 10. After being heated by the high-temperature flue gas passing through the filter screen 4, the bimetallic spiral disk 14 will drive the transmission rod 16 to rotate. (See attached instruction manual.) Figure 11 It can be seen that the bimetallic spiral disc 14 is set at the bottom of the filter screen 4. Therefore, the bimetallic spiral disc 14 will only be heated after the high-temperature flue gas passes through the filter screen 4. One end of the bimetallic spiral disc 14 is fixedly connected to the side rod of the connecting box 10. The bimetallic spiral disc 14 is fixedly connected to the connecting rod 15. The bimetallic spiral disc 14 is connected to the transmission rod 16 through the connecting rod 15. The connecting rod 15 and the transmission rod 16 are fixedly connected. Therefore, when the temperature changes, the bimetallic spiral disc 14 will drive the transmission rod 16 to rotate through the connecting rod 15. One end of the slider 17 is rotatably connected to the transmission rod 16, and the slider 17 is slidably connected to the scraper 13.

[0027] The phase change gas storage mechanism includes a piston cylinder 18, a piston rod 19, a return spring 20, a cylinder 21, and a gas tank 22. The piston cylinder 18 is located on the top of the connecting box 10. The piston rod 19 is slidably connected to the piston cylinder 18. The two ends of the piston rod 19 are slidably connected to the piston cylinder 18 and the cylinder 21, respectively. The piston cylinder 18 is filled with heat-sensitive wax. When the temperature of the piston cylinder 18 rises, the heat-sensitive wax melts and expands, pushing the piston rod 19 to move along the cylinder 21. The return spring 20 is used to drive the piston rod 19 to return to its original position when the temperature drops. When the piston rod 19 moves along the cylinder 21, it compresses air into the gas tank 22.

[0028] The spray cleaning mechanism includes a pressure relief valve 23, a mounting plate 24, and nozzles 25. The pressure relief valve 23 is connected to the air tank 22 and is connected to the mounting plate 24 through a pipe. Several nozzles 25 are provided on the mounting plate 24.

[0029] Working principle: When in use, the centrifugal fan 11 generates negative pressure inside the exhaust box 2, thereby drawing the flue gas into the exhaust box 2. When the flue gas enters the exhaust box, the filter screen 4 filters out the oil. When in use, the high-temperature flue gas heats the bimetallic spiral disk 14, which in turn drives the transmission rod 16 to rotate. When the transmission rod 16 rotates, it drives the scraper 13 through the slider 17 to scrape off the oil stains attached to the filter screen 4. During each use, the high temperature causes the heat-sensitive wax to melt and expand, pushing the piston rod 19 to move along the cylinder 21. Air is pumped into the air tank 22 for storage. After use, when the temperature drops, the return spring 20 drives the piston rod 19 to return to its original position. This cycle repeats, continuously compressing air into the air tank 22. In this embodiment, the amount of air compressed by the piston rod 19 in a single movement in the cylinder 21 is much less than the storage capacity of the air tank 22. Therefore, after multiple uses of the induction cooker, the pressure in the air tank 22 will continuously increase. When the pressure in the air tank 22 reaches the opening value of the pressure relief valve 23, the pressure relief valve 23 will open, thereby spraying air through the nozzle 25 to clean the holes of the filter screen 4.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
