Description

Technical Field

[0001] This invention relates to the field of kitchen appliances technology, and in particular to a stove. Background Technology

[0002] When stir-frying, to improve the texture of food, it's necessary to constantly stir-fry to ensure even heating. However, during this process, the cooking oil at the bottom of the pan is stirred up and splatters onto other parts of the pan. Because the temperature of the pan is much higher than that of the oil droplets, and the oil droplets are smaller, heat is conducted from the pan's surface to the oil droplets, causing them to heat up rapidly and produce fumes. Excessively high oil temperatures can destroy nutrients in food and produce substances harmful to the human body, and excessive fumes can also negatively impact health.

[0003] Furthermore, during this process, because the cooking oil at the bottom of the pot is of greater mass and in close contact with the food, the heat from the cooking oil at the bottom of the pot is quickly transferred to the food. In contrast, the cooking oil on the sides of the pot is of less mass and is not covered by the food. Therefore, the amount of oil smoke generated on the sides of the pot is usually greater than that generated at the bottom of the pot. Summary of the Invention

[0004] Therefore, it is necessary to provide a stove that can reduce the generation of oil fumes without affecting the cooking effect, in order to address the above problems.

[0005] This invention provides a stove, comprising: a stove platform for placing a pot; a heating device disposed on the stove platform for heating the bottom of the pot; a cooling device comprising a cooling fluid assembly and a spray assembly connected to each other, the spray assembly being disposed on the stove platform and having a plurality of nozzles surrounding the heating device, the cooling fluid assembly being able to spray cooling fluid through the nozzles of the spray assembly onto the pot wall; a temperature detection device for measuring the temperature of the pot wall; and a control device electrically connected to both the cooling fluid assembly and the temperature detection device, wherein when the temperature detection device detects that the pot wall has been heated to a first preset temperature, the control device controls the cooling fluid assembly to operate.

[0006] In the aforementioned stove, the heating device heats the bottom of the pot placed on the stovetop, and the pot wall heats up simultaneously with the bottom. A temperature detection device monitors the temperature of the pot wall, and a control device controls the opening and closing of the cooling fluid assembly based on the temperature detected by the temperature detection device. When the temperature detection device detects that the temperature of the pot wall has risen to a first preset temperature, the control device controls the cooling fluid assembly to start working. The cooling fluid assembly sprays cooling fluid onto the pot wall through the nozzles of the spray assembly to cool the pot wall and prevent the oil splashed onto the pot wall during stir-frying from rapidly decomposing and producing a large amount of oil fumes. Since the nozzles are surrounding the heating device, it can be ensured that the pot wall can be sprayed with cooling fluid from all directions. At the same time, since the heating device always heats the bottom of the pot, and the cooling fluid sprayed from the nozzles does not spray onto the bottom of the pot, it does not affect the temperature of the bottom of the pot, and therefore does not affect the cooking effect of the food in the pot. Thus, the stove can reduce the generation of oil fumes during cooking without affecting the cooking effect.

[0007] In one embodiment, when the temperature detection device detects that the pot wall has cooled down to a second preset temperature, the control device controls the cooling fluid assembly to stop working, wherein the first preset temperature is higher than the second preset temperature.

[0008] This setting ensures that the temperature of the pot wall is always maintained between the first and second preset temperatures, preventing it from becoming too high or too low, thus improving the cooking effect.

[0009] In one embodiment, the first preset temperature is 165°C to 185°C, and the second preset temperature is 150°C to 170°C.

[0010] This setup avoids producing excessive oil fumes, preserves the nutritional value of the ingredients, and ensures cooking efficiency.

[0011] In one embodiment, the spraying assembly includes a first annular tube mounted on the stovetop, the first annular tube being disposed on the outer periphery of the heating device, and the nozzle being opened on the upper surface of the first annular tube.

[0012] With this design, the first annular tube can be placed directly on the stovetop, making installation simple and convenient. It also facilitates disassembly and cleaning of the first annular tube, preventing a large amount of oil residue at the nozzle from affecting the spraying effect of the cooling fluid.

[0013] In one embodiment, the plurality of nozzles form at least two concentric circles of different diameters on the upper surface of the first annular tube.

[0014] This design results in a larger contact area between the cooling fluid from the nozzle and the pot wall, which helps to improve the cooling efficiency of the pot wall.

[0015] In one embodiment, the injection assembly further includes a second annular tube and a plurality of connecting tubes. The second annular tube is concentrically arranged with the first annular tube and communicates with the cooling fluid assembly. The plurality of connecting tubes are evenly spaced along the circumference of the second annular tube, and the two ends of the connecting tubes are respectively connected to the first annular tube and the second annular tube.

[0016] With this configuration, the cooling fluid generated by the cooling fluid assembly can first fill the second annular pipe, and then enter the first annular pipe evenly through multiple connecting pipes, so that the cooling fluid in the first annular pipe can be evenly sprayed out from different nozzles, ensuring that every part along the circumference of the pot wall can be evenly sprayed with cooling fluid.

[0017] In one embodiment, the injection assembly further includes at least two air intake pipes, which are evenly spaced along the circumference of the second annular pipe. One end of each air intake pipe communicates with the lower surface of the second annular pipe, and the other end extends to the lower side of the stove and communicates with the cooling fluid assembly.

[0018] With this configuration, the cooling fluid generated by the cooling fluid assembly can enter the second annular pipe evenly through at least two air inlet pipes. The air inlet pipes extend to the underside of the stove and connect with the cooling fluid assembly to avoid exposing the connection structure, ensuring the overall appearance of the stove is neat, and also avoiding taking up too much space above the stove.

[0019] In one embodiment, the diameter of the second annular tube is smaller than the diameter of the first annular tube, and two adjacent connecting tubes form a clearance groove with the first annular tube and the second annular tube; the stove also includes a pot rack for supporting the pot, and the support legs of the pot rack are mounted on the stove platform through the clearance groove.

[0020] This design allows for easy installation of the pot holder, ensuring that the pot holder and the spray assembly do not interfere with each other. Furthermore, both the pot holder and the spray assembly can be easily disassembled and installed, facilitating user cleaning or replacement of the pot holder and the spray assembly.

[0021] In one embodiment, the cooling fluid assembly includes an atomizer and a fan that are in communication with each other, the fan being used to blow atomized water vapor generated by the atomizer toward the spray assembly.

[0022] With this configuration, the atomized water vapor generated by the atomizer can quickly absorb a large amount of heat from the pot wall through heat conduction, and at the same time, it can also undergo forced convection heat exchange with the pot wall, thereby increasing the cooling rate of the pot wall. Furthermore, after the atomized water vapor comes into contact with the pot wall, it will flow upward along the outer surface of the pot wall. After the atomized water vapor flows to the upper edge of the pot wall, it will be affected by the thermophoretic force of the inner wall of the pot, and tend to roll inward, which helps to push the oil fumes inward and prevent the oil fumes from spreading outward.

[0023] In one embodiment, the nozzle is directed toward the pot wall near the pot opening. to The area.

[0024] This design ensures that the cooling fluid falls on the pot wall at a distance from the bottom of the pot, preventing it from splashing onto the bottom and allowing the bottom of the pot to maintain a consistently high temperature.

[0025] In one embodiment, the inner diameter of the nozzle is less than 5 mm.

[0026] This design ensures the effective spraying of cooling fluid while preventing the nozzle from being too large, which could cause oil, dust, or other foreign matter to fall into the first annular pipe. Attached Figure Description

[0034] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application.

The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0039] To improve the texture of food, it's necessary to stir-fry constantly to ensure even heating. However, during this process, the cooking oil at the bottom of the pan is stirred up and splatters onto other parts of the pan. Since the temperature of the pan is much higher than that of the oil droplets, and the oil droplets are relatively small, heat is conducted from the pan's surface to the oil droplets, causing them to heat up rapidly and produce smoke.

[0040] It's understandable that cooking oil produces a large amount of thermal oxidation and decomposition products at high temperatures. When the temperature reaches 170℃, a small amount of initial decomposition blue smoke appears. As the temperature rises, the decomposition rate of cooking oil accelerates, and when the temperature reaches 250℃, a large amount of oil fumes are produced, affecting human health. Furthermore, when the oil temperature is below 175℃, 60% to 70% of vitamin C and more than 80% of riboflavin and carotene are retained; however, when the oil temperature exceeds 240℃, not only are most nutrients destroyed, but many substances harmful to the human body are also produced.

[0041] Furthermore, during this process, because the cooking oil at the bottom of the pot is of greater mass and in close contact with the food, the heat from the cooking oil at the bottom of the pot is quickly transferred to the food. In contrast, the cooking oil on the sides of the pot is of less mass and is not covered by the food. Therefore, the amount of oil smoke generated on the sides of the pot is usually greater than that generated at the bottom of the pot.

[0042] To solve the above problems, such as Figures 1 to 5 As shown, the present invention provides a stove that can reduce the generation of oil fumes without affecting the cooking effect.

[0043] like Figure 1As shown, specifically, the stove includes a stovetop 1, a heating device 2, a cooling device 3, a temperature detection device 6, and a control device 4, wherein: the stovetop 1 is used to place the pot 7; the heating device 2 is located on the stovetop 1 and is used to heat the bottom 71 of the pot 7; the cooling device 3 includes a cooling fluid assembly 31 and a spray assembly 32 that are interconnected, the spray assembly 32 is located on the stovetop 1 and has multiple nozzles 321 surrounding the heating device 2, the cooling fluid assembly 31 can spray cooling fluid through the nozzles 321 of the spray assembly 32 onto the pot wall 72 of the pot 7; the temperature detection device 6 is used to measure the temperature of the pot wall 72; the control device 4 is electrically connected to both the cooling fluid assembly 31 and the temperature detection device 6, and when the temperature detection device 6 detects that the pot wall 72 has been heated to a first preset temperature, the control device 4 controls the cooling fluid assembly 31 to work.

[0044] As mentioned earlier, existing stoves often produce excessive oil fumes during cooking due to excessively high oil temperatures, which damages the nutrients in food and affects human health. However, in the stove provided in this embodiment of the invention, the pot 7 is placed on the stovetop 1, and the bottom 71 of the pot is heated by the heating device 2. Since the pot 7 is a heat-conducting structure, the pot wall 72 also heats up simultaneously with the bottom 71, thus heating the food inside the pot 7. The temperature detection device 6 monitors the temperature of the pot wall 72, and the control device 4 controls the opening and closing of the cooling fluid assembly 31 based on the temperature detected by the temperature detection device 6. When the temperature detection device 6 detects that the temperature of the pot wall 72 has risen to a first preset temperature, the control device 4 controls the cooling fluid assembly 31 to start working. The component 31 can spray cooling fluid through the nozzle 321 of the spray assembly 32 onto the pot wall 72, cooling the pot wall 72 and preventing the oil splashed onto the pot wall 72 during stir-frying from rapidly decomposing and generating a large amount of oil fumes. Since the nozzle 321 is surrounding the heating device 2, it can ensure that the pot wall 72 can be sprayed with cooling fluid from all directions. At the same time, since the heating device 2 always heats the bottom of the pot 71, and the cooling fluid sprayed from the nozzle 321 does not spray onto the bottom of the pot 71, it will not affect the temperature of the bottom of the pot 71, and therefore will not affect the cooking effect of the food in the cookware 7. Thus, the stove can reduce the generation of oil fumes during cooking without affecting the cooking effect of the food.

[0045] The temperature detection device 6 can be an infrared sensor, which is a non-contact temperature measuring device. The infrared sensor can be placed on the stovetop 1, and the infrared rays c emitted by the sensor can be aimed at the area above the line b on the pot wall 72. This will not affect the normal use of the pot 7, nor will it require moving the temperature detection device 6, making temperature measurement convenient. Of course, the temperature detection device 6 can also be a thermometer or other contact or non-contact sensors installed on the pot wall 72, as long as it can monitor the temperature of the pot wall 72. This embodiment of the invention does not impose specific limitations here.

[0046] like Figure 1 As shown in the illustrated embodiment, the cooling fluid assembly 31 includes an atomizer 311 and a fan 312 connected to each other. The fan 312 blows the atomized water vapor generated by the atomizer 311 toward the spray assembly 32. The atomizer 311 generates atomized water vapor, and the fan 312 accelerates the flow rate of the atomized water vapor, causing it to be sprayed out rapidly. After the atomized water vapor comes into contact with the outer surface of the pot wall 72, some of the atomized water vapor adheres to the outer surface of the pot wall 72. Due to the high specific heat of the atomized water vapor, it can quickly absorb a large amount of heat from the pot wall 72 through heat conduction. Some of the atomized water vapor also flows on the outer surface of the pot wall 72, resulting in forced convection heat transfer between the atomized water vapor and the pot wall 72, thereby increasing the cooling rate of the pot wall 72.

[0047] Furthermore, after the atomized water vapor comes into contact with the pot wall 72, it flows upward along the outer surface of the pot wall 72. Upon reaching the upper edge of the pot wall 72, the atomized water vapor is subjected to the thermophoretic force of the inner wall of the pot 72, causing it to tend to roll inwards. This helps to push the oil fumes inwards and prevent them from spreading outwards. Simultaneously, the atomized water vapor can also come into contact with small oil fume particles on the pot wall 72 or in the air, increasing the size of the oil fume particles. Since the range hood's ability to capture large oil fume particles is greater than its ability to capture small oil fume particles, the increased size of the oil fume particles also helps the range hood capture the oil fumes, improving the grease extraction rate of the range hood and reducing the amount of oil fume floating in the air.

[0048] In another embodiment, the cooling fluid assembly 31 may only include an atomizer 311. After the atomizer 311 generates atomized water vapor, the internal air pressure of the atomizer 311 increases, exceeding the external atmospheric pressure, and the atomized water vapor can be sprayed out under the action of the pressure difference. Alternatively, the cooling fluid assembly 31 may only include a fan 312, which can directly accelerate air and blow it towards the pot wall 72. Of course, in other embodiments, the cooling fluid assembly 31 may also be configured with other structures capable of generating cooling fluid or transporting external cooling fluid to the spray assembly 32. This embodiment of the invention does not impose specific limitations here.

[0049] like Figure 1As shown, the pot wall 72 gradually cools down under the action of the cooling fluid. To prevent the pot wall 72 from becoming too cold and affecting the cooking effect, when the temperature detection device 6 detects that the pot wall 72 has cooled down to the second preset temperature, the control device 4 controls the cooling fluid assembly 31 to stop working. The first preset temperature is higher than the second preset temperature. At this time, the cooling fluid assembly 31 stops generating cooling fluid, and the nozzle 321 also stops spraying cooling fluid onto the pot wall 72. The temperature of the pot wall 72 gradually rises again under the action of the heating device 2. When the temperature of the pot wall 72 rises back to the first preset temperature, the control device 4 controls the cooling fluid assembly 31 to work again to cool the pot wall 72 again, and so on in a cycle. In this way, the temperature of the pot wall 72 can always be maintained between the first preset temperature and the second preset temperature, so that the temperature is neither too high nor too low, thereby improving the cooking effect.

[0050] Because a small amount of initial blue smoke from decomposition begins to appear when the oil temperature reaches 170℃, and when the oil temperature is below 175℃, 60% to 70% of vitamin C and over 80% of riboflavin and carotene are retained. Therefore, the first preset temperature can be set to 165℃ to 185℃, and the second preset temperature can be set to 150℃ to 170℃, with the first preset temperature being higher than the second. Maintaining the temperature within this range avoids the generation of excessive oil fumes, does not damage the nutritional value of the food, and also ensures cooking efficiency.

[0051] like Figure 2 As shown in the illustrated embodiment, the cooling fluid ejected from the nozzle 321 is sprayed along direction a towards the pot wall 72 and will land on the pot wall 72 near the pot opening. The area. Along the height direction of the pot 7, line b is the height of the pot wall 72. The cooling fluid sprayed from nozzle 321 onto the pot wall 72 will fall in the area above line b, while the area below line b is the area that the heating device 2 can heat. This ensures that the cooling fluid falls on the pot wall 72 at a distance from the pot bottom 71, preventing it from splashing onto the pot bottom 71 and further avoiding affecting its temperature. This allows the pot bottom 71 to maintain a consistently high temperature, ensuring optimal cooking results.

[0052] Of course, in other embodiments, the cooling fluid ejected from the nozzle 321 can also be sprayed along direction a towards the pot wall 72 near the pot opening. to The area is fine as long as it doesn't affect the temperature of the bottom of the pot (71°C).

[0053] like Figures 1 to 2As shown, the spray assembly 32 includes a first annular tube 322 mounted on the stove 1. The first annular tube 322 is located on the outer periphery of the heating device 2, and the nozzle 321 is opened on the upper surface of the first annular tube 322. The first annular tube 322 can be directly placed on the stove 1, which is simple and convenient to install without disassembling the stove 1. This facilitates cleaning of the first annular tube 322 after disassembly and avoids the accumulation of a large amount of oil residue at the nozzle 321, which would affect the spraying effect of the cooling fluid.

[0054] like Figure 4 As shown, multiple nozzles 321 form at least two concentric circles of different diameters on the upper surface of the first annular tube 322. The presence of at least two concentric circles increases the contact area between the cooling fluid from the nozzles 321 and the pot wall 72, which helps to improve the cooling efficiency of the pot wall 72.

[0055] In the illustrated embodiment, multiple nozzles 321 forming the same circle are evenly spaced along the circumference of the first annular pipe 322 to ensure that the cooling fluid can be evenly sprayed onto the pot wall 72, thereby allowing the pot wall 72 to cool down uniformly. Of course, in other embodiments, the multiple nozzles 321 may also be intermittently or partially distributed on the upper surface of the first annular pipe 322, as long as they can spray cooling fluid onto the pot wall 72 to cool it down. This embodiment of the invention does not impose specific limitations here.

[0056] The nozzle 321 can be circular, with an inner diameter of less than 5mm. This ensures effective cooling fluid ejection while preventing the nozzle from becoming too large, which could cause oil, dust, or other foreign matter to fall into the first annular pipe 322. Alternatively, the nozzle 321 can be elliptical, square, polygonal, or other regular or irregular shapes, as long as the cooling fluid can be ejected normally. This embodiment of the invention does not impose specific limitations on these shapes.

[0057] like Figure 4 As shown, the spray assembly 32 also includes a second annular pipe 323 and multiple connecting pipes 324. The second annular pipe 323 is concentrically arranged with the first annular pipe 322 and is connected to the cooling fluid assembly 31. The multiple connecting pipes 324 are evenly spaced along the circumference of the second annular pipe 323, and their two ends are connected to the first annular pipe 322 and the second annular pipe 323, respectively. The cooling fluid generated by the cooling fluid assembly 31 can first enter the second annular pipe 323, filling it with cooling fluid. The cooling fluid in the second annular pipe 323 then evenly enters the first annular pipe 322 through the multiple connecting pipes 324, filling it with cooling fluid as well. In this way, the cooling fluid in the first annular pipe 322 can be evenly sprayed out from different nozzles 321, ensuring that every part along the circumference of the pot wall 72 can be evenly sprayed with cooling fluid, thus ensuring the cooling effect on the pot wall 72.

[0058] In the illustrated embodiment, there are four connecting pipes 324, which are evenly spaced along the circumference of the second annular pipe 323 to ensure that the cooling fluid in the second annular pipe 323 can enter the first annular pipe 322 evenly through the four connecting pipes 324. In other embodiments, the number of connecting pipes 324 may be two, three, or more, and this embodiment of the invention does not impose specific limitations.

[0059] like Figure 2 and Figure 4 As shown, the diameter of the second annular pipe 323 is smaller than the diameter of the first annular pipe 322. Two adjacent connecting pipes 324, together with the first annular pipe 322 and the second annular pipe 323, form a clearance groove 326. The stove also includes a pot rack 5 for supporting the pot 7. The support legs of the pot rack 5 are mounted on the stove platform 1 through the clearance groove 326. The smaller diameter of the second annular pipe 323 compared to the first annular pipe 322 prevents the overall volume of the spray assembly 32 from being too large and occupying too much space on the stove platform 1. When installing the pot rack 5 and the spray assembly 32, the spray assembly 32 is first placed on the stove platform 1. Then, the support legs of the pot rack 5 are aligned with the clearance groove 326 of the spray assembly 32. After the support legs of the pot rack 5 pass through the clearance groove 326, it is mounted on the stove platform 1, and the pot 7 can be placed on the pot rack 5. The clearance groove 326 facilitates the installation of the pot frame 5, ensuring that the pot frame 5 and the spray assembly 32 do not interfere with each other. Both the pot frame 5 and the spray assembly 32 can be easily disassembled and installed, allowing users to disassemble and clean or replace the pot frame 5 and the spray assembly 32.

[0060] like Figures 3 to 4 As shown, the spray assembly 32 also includes at least two air inlet pipes 325, which are evenly spaced along the circumference of the second annular pipe 323. One end of each air inlet pipe 325 is connected to the lower surface of the second annular pipe 323, and the other end extends to the lower side of the stove 1 and connects to the cooling fluid assembly 31. The at least two air inlet pipes 325 allow the cooling fluid generated by the cooling fluid assembly 31 to enter the second annular pipe 323 evenly, and to be evenly distributed to the first annular pipe 322 through the connecting pipe 324 within the second annular pipe 323, further enabling the cooling fluid to be evenly sprayed out from different nozzles 321. The air inlet pipes 325 extending to the lower side of the stove 1 and connecting to the cooling fluid assembly 31 avoids exposing the connection structure, ensuring a neat overall appearance of the stove, and also avoids occupying too much space above the stove 1.

[0061] like Figure 5As shown in the illustrated embodiment, the spray assembly 32 includes an upper cover 3201 and a lower cover 3202. The upper cover 3201 and the lower cover 3202 can be joined together by welding, gluing, or other methods to form a first annular tube 322, a second annular tube 323, and a connecting tube 324. The nozzle 321 is formed on the upper cover 3201, and the air inlet tube 325 protrudes from the lower cover 3202 to facilitate the manufacturing and processing of the spray assembly 32. Of course, in other embodiments, the first annular tube 322, the second annular tube 323, the connecting tube 324, and the air inlet tube 325 can also be processed separately and connected by welding, gluing, or other methods to form the spray assembly 32, or the spray assembly 32 can also be an integral structure. This embodiment of the invention does not impose specific limitations here.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
