Abstract
Description
Technical Field
[0001] This invention relates to the field of kitchenware, and in particular to a stove control method and a stove. Background Technology
[0002] When cooking with pots and pans on a stove, especially when stewing or simmering liquids, overflowing is a common problem. High temperatures cause liquids to boil rapidly, forming numerous bubbles that cannot dissipate quickly enough. These bubbles accumulate, causing the liquid level to rise rapidly beyond the edge of the pot and overflow. Overflowing makes cleaning the pot and stove difficult or damages their surfaces, and results in uneven heating of the food, affecting both cooking quality and taste. Furthermore, when using a gas stove, overflowing liquid may flow near the burner, extinguishing the flame or causing gas leaks, creating serious safety hazards. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to overcome the defect of pots and pans easily overflowing in the prior art, and to provide a stove control method.
[0004] The present invention solves the above-mentioned technical problems through the following technical solution:
[0005] A stove control method is used to control a stove for heating cookware, the stove including at least two heating zones, each heating zone being located in a different direction from the center of the stove, the stove control method comprising the following steps:
[0006] Alternately switch between the first heating mode and the second heating mode;
[0007] The first heating mode is: controlling the first heating zone in the heating area to heat the bottom of the pot, so that the output power of the first heating zone is greater than the output power of the other heating zones;
[0008] The second heating mode is: controlling the second heating zone in the heating area to heat the bottom of the pot, so that the output power of the second heating zone is greater than the output power of the other heating zones.
[0009] In this technical solution, by providing the stove control method, the stove can alternately control the high power output of the first heating zone and the second heating zone, thereby alternately heating different directions of the pot, so that the heated area of the liquid in the pot changes continuously, disrupting the stable boiling state of the liquid, making it difficult for bubbles to continuously accumulate in the same position, reducing foam accumulation, and reducing the possibility of overflow.
[0010] Preferably, the steps of the stove control method further include:
[0011] Control the stove to remain in the first heating mode; and / or,
[0012] The stove is kept in the second heating mode.
[0013] In this technical solution, the above-mentioned settings allow the stove to flexibly adapt to irregularly shaped cookware. By continuously controlling the high power output of the first or second heating zone according to the shape of the cookware, uniform heating can be achieved, avoiding uneven heating or heat waste caused by the irregular shape of the cookware, thus meeting diverse cooking needs.
[0014] Preferably, the cooktop further includes an outer ring region located around each of the heating zones, and the cooktop control method further includes the following steps:
[0015] Control the output power of the outer ring area of the stove.
[0016] In this technical solution, the above-mentioned settings allow the stove to flexibly adapt to cookware of different sizes. When a larger cookware is selected, the output power of the outer ring area is greater, which allows the cookware to be heated more evenly and is less likely to burn the food; when a smaller cookware is selected, the output power of the outer ring area is less, which avoids heat waste and also prevents excessive flames from overflowing from the side wall of the pot, thus avoiding the safety hazard of burning the user.
[0017] A cooktop includes a controller that, when operating, performs the control method as described in any of the preceding claims.
[0018] In this technical solution, by providing this stove, the possibility of overflowing pots can be reduced.
[0019] Preferably, the cooktop includes a central ring area, which includes at least two heating zones.
[0020] In this technical solution, through the above settings, when switching between the first heating mode and the second heating mode, the stable boiling state of the liquid in the central ring of the larger pot and the edge of the smaller pot is disrupted, so that the alternating heating mode has a good anti-overflow effect on pots of various sizes, improving the versatility of the stove; and without changing the heating status of the liquid in the center of the pot, cooking time is saved.
[0021] Preferably, the middle ring region includes four sectors of equal length, the first heating region in the middle ring region includes two diagonally distributed sectors, and the second heating region in the middle ring region includes another two diagonally distributed sectors.
[0022] In this technical solution, through the above-described configuration, when switching between the first and second heating modes, the diagonally evenly distributed first and second heating areas can uniformly transfer heat to different parts of the cookware. Furthermore, the alternating activation of the diagonally distributed sectors promotes good convection circulation of the liquid within the cookware. This convection helps break the stable boiling state of the liquid, reduces the continuous accumulation of bubbles in the same location, and further reduces the risk of overflow. Moreover, when the cookware is continuously controlled in either the first or second heating mode, the diagonally evenly distributed first and second heating areas can better adapt to elongated cookware, further optimizing heat distribution.
[0023] Preferably, the stove further includes an outer ring area located on the outer periphery of the central ring area.
[0024] In this technical solution, the above settings enable the stove to be adapted to larger pots.
[0025] Preferably, the stove further includes an inner ring region located on the inner periphery of the central ring region.
[0026] In this technical solution, the above settings enable the stove to be adapted to smaller pots.
[0027] Preferably, the inner ring area is a circular heating area located in the middle of the corresponding pot of the stove.
[0028] In this technical solution, through the above-mentioned settings, the inner ring area specifically heats the center of the pot, effectively shortening the cooking time and improving the cooking efficiency, while having less impact on the boiling situation at the edge of the pot and not weakening the anti-overflow effect.
[0029] Preferably, the stove is a gas stove.
[0030] In this technical solution, the above settings enable the stove to be suitable for various cookware materials and compatible with different cooking environments.
[0031] The positive and progressive effects of this invention are as follows:
[0032] By providing the stove control method and stove, the stove can alternately control the high power output of the first heating zone and the second heating zone, thereby alternately heating different directions of the pot, causing the heating area of the liquid in the pot to change continuously, disrupting the stable boiling state of the liquid, making it difficult for bubbles to continuously accumulate in the same position, reducing foam accumulation, and reducing the possibility of overflow.

[0053] Center 14 Detailed Implementation
[0054] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.
[0055] like Figure 1 As shown, this embodiment provides a stove control method for controlling a stove 1 used for heating cookware (not shown in the figure). The stove 1 includes at least two heating zones, each located in a different direction from the center 14 of the stove 1. The steps of the stove control method include:
[0056] Alternately switch between the first heating mode S1 and the second heating mode S2.
[0057] The first heating mode S1 is: controlling the first heating area 1111 in the heating area to heat the bottom of the pot, so that the output power of the first heating area 1111 is greater than the output power of other heating areas;
[0058] The second heating mode S2 is: controlling the second heating zone 1112 in the heating zone to heat the bottom of the pot, so that the output power of the second heating zone 1112 is greater than the output power of other heating zones.
[0059] In this way, by providing the stove control method, the stove 1 can alternately control the high power output of the first heating zone 1111 and the second heating zone 1112, thereby alternately heating different directions of the pot, so that the heated area of the liquid in the pot changes continuously, disrupting the stable boiling state of the liquid, making it difficult for bubbles to continuously accumulate in the same position, reducing foam accumulation, and reducing the possibility of overflow.
[0060] It is important to note that:
[0061] First, the phrase "alternating between the first heating mode S1 and the second heating mode S2" in this article is not limited to the continuous alternation between the two steps of the first heating mode S1 and the second heating mode S2, but may include other steps. The following situations are also included in the scope defined above: there is a third heating mode S3, which controls the third heating area in the heating area to heat the bottom of the pot, so that the output power of the third heating area is greater than that of other heating areas; the first heating mode S1, the second heating mode S2, and the third heating mode S3 are executed in a continuous cycle.
[0062] Second, the phrase "make the output power of heating zone XX greater than that of other heating zones" in this article includes both situations where the output power of heating zone XX is increased and the output power of other heating zones is decreased (e.g., the output power of the first heating zone 1111 is 1200W and the output power of other heating zones is 600W), and situations where heating zone XX is turned on and other heating zones are turned off or partially turned off (e.g., turning on the first heating zone 1111 with a larger power and turning off the second heating zone 1112, and turning on the inner ring zone 121 and the outer ring zone 112 with a smaller power).
[0063] Third: Center 14 refers to the area on the stove 1 that corresponds to the lowest point of the pot / the middle of the bottom of the pot. For a single burner, Center 14 is the heating center of that burner (usually also the center of the top view in a geometric sense).
[0064] In this embodiment, the steps of the stove control method further include:
[0065] S31, control the stove 1 to remain in the first heating mode S1; and,
[0066] S32, Control the stove 1 to remain in the second heating mode S2.
[0067] This step allows the stove 1 to flexibly adapt to irregularly shaped cookware. By continuously controlling the high power output of the first heating zone 1111 or the second heating zone 1112 according to the shape of the cookware, uniform heating can be achieved, avoiding uneven heating or heat waste caused by irregular cookware shapes (e.g., oval fish pots, specially designed barbecue pans with polygonal bottoms), thus meeting diverse cooking needs. Of course, in other embodiments, steps S31 and S32 may not be included, or only one of these steps may be included.
[0068] In this embodiment, the cooktop 1 further includes an outer ring region 112 located around each heating zone, and the cooktop control method further includes the following steps:
[0069] S4. Control the output power of the outer ring area 112 of the stove 1.
[0070] This step allows the stove 1 to flexibly adapt to cookware of different sizes. When a larger cookware is selected, the output power of the outer ring area 112 is greater, which allows the cookware to be heated more evenly and is less likely to burn the food; when a smaller cookware is selected, the output power of the outer ring area 112 is less, avoiding heat waste and also preventing excessive flames from overflowing from the side wall of the cookware, thus avoiding the safety hazard of burning the user. Of course, in other embodiments, S4 may not be included.
[0071] It should be noted that S1, S2, S31, S32 and S4 are not in any order.
[0072] like Figures 2-4 This embodiment also provides a stove 1, which includes a controller (not shown in the figure). When the controller is running, it executes the control method described above to reduce the possibility of overflowing.
[0073] In this embodiment, the cooktop 1 includes a central ring region 111, which comprises at least two heating zones. When alternating between the first heating mode S1 and the second heating mode S2, the stable boiling state of the liquid in the central ring portion of larger pots and the edge of smaller pots is disrupted. This results in better anti-overflow performance for pots of various sizes under alternating heating modes, improving the versatility of the cooktop 1. Furthermore, it does not alter the heating status of the liquid in the center 14 of the pot, saving cooking time.
[0074] Please see Figure 3a , Figure 3b In this embodiment, the central ring region 111 includes four equally long sectors. The first heating region 1111 on the central ring region 111 includes two diagonally distributed sectors, and the second heating region 1112 on the central ring region 111 includes another two diagonally distributed sectors. When switching between the first heating mode S1 and the second heating mode S2, the diagonally evenly distributed first heating region 1111 and the second heating region 1112 can both evenly transfer heat to different parts of the pot, and the alternating activation of the diagonally distributed sectors can promote good convection circulation of the liquid in the pot. This convection helps to break the stable boiling state of the liquid, reduce the continuous accumulation of bubbles in the same position, and further reduce the risk of overflow. Furthermore, when the stove 1 is continuously controlled in the first heating mode S1 or the second heating mode S2, the diagonally evenly distributed first heating region 1111 and the second heating region 1112 can also better adapt to long pots, further optimizing the heat distribution.
[0075] In this embodiment, the stove 1 also includes an outer ring region 112 located on the outer periphery of the middle ring region 111, which allows the stove 1 to be adapted to larger pots.
[0076] In this embodiment, the stove 1 also includes an inner ring region 121 located on the inner periphery of the middle ring region 111, which allows the stove 1 to be adapted to smaller pots.
[0077] In this embodiment, the inner ring area 121 is a circular heating area located in the middle of the corresponding pot on the stove 1, which is used to specifically heat the center 14 of the pot, effectively shortening the cooking time, improving the cooking efficiency, and having less impact on the boiling situation at the edge of the pot, without weakening the anti-overflow effect.
[0078] In this embodiment, the stove 1 is a gas stove, making it suitable for various cookware materials and compatible with different cooking environments. Of course, in other embodiments, the stove can also be an induction cooker, an infrared stove, or a steam stove, etc.
[0079] Please refer to the following: Figure 2 , Figure 3a , Figure 3b In this embodiment, the stove 1 includes an outer ring burner 11 corresponding to the middle ring region 111 and the outer ring region 112, an inner ring burner 12 corresponding to the inner ring region 121, and a mixing chamber 13 that supplies air-fuel mixture to the outer ring burner 11 and the inner ring burner 12.
[0080] Please refer to the following: Figure 4 , Figure 5The mixing chamber 13 is provided with an inner ring gas passage 131 corresponding to the inner ring region 121, a first gas passage 132 corresponding to the first heating region 1111, a second gas passage 133 corresponding to the second heating region 1112, and an outer ring gas passage 134 corresponding to the outer ring region 112. The controller can realize the aforementioned control method by controlling the opening degree / opening / closing state of each gas passage.
[0081] In this embodiment, the stove 1 can be a smart stove and is equipped with a smart voice control module. The smart voice control module includes a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the opening / closing state of each gas channel to perform corresponding operations, thereby realizing the intelligent control of the stove 1 and improving the user experience of using the smart stove.
