DETAILED DESCRIPTION
[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments.

It is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.
[0035] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.
[0036] It should be noted that, in the absence of conflict, the features in the embodiments of the present application may be combined with each other.
[0037] Figure 1 Schematic diagram of an integrated stove 010 and a pot 020 in the related art. Figure 1 As shown, the integrated stove 010 in the related art includes a stove body 100, a gas stove 200 and a suction mechanism 300. The gas stove 200 includes a burner 210, and the burner 210 is used to heat the pot 020. The suction mechanism 300 has a smoke outlet 301, and the smoke outlet 301 is located above the burner 210 and the pot 020. When cooking, there is a large gap between the pot 020 and the suction mechanism 300, so that part of the heat released by the burner 210 will move upward from the gap with the rising airflow and be lost; at the same time, part of the heat released by the burner 210 will also reach the suction mechanism 300 by radiation and be absorbed by the suction mechanism 300. The direction of heat loss is as follows. Figure 1 In the prior art, the lost heat accounts for a large proportion, which can reach 5% of the total heat generated by the burner. It can be seen that the thermal efficiency of the integrated stove in the prior art is low.
[0038] In order to improve the deficiencies in the above-mentioned related technologies, an embodiment of the present application provides an integrated stove and a control method thereof, which reduces the heat loss of the burner and improves the thermal efficiency of the integrated stove by adjusting the distance between the heat shield and the bottom of the pot.
[0039] Figure 2 This is a schematic diagram of an integrated stove 010 and a cooker 020 in one embodiment of the present application (the suction mechanism 300 is exploded); Figure 3 This is a schematic diagram of an integrated stove 010 during cooking in one embodiment of the present application. Figure 2 and Figure 3 As shown, the integrated stove 010 provided in the embodiment of the present application includes a stove body 100, a gas stove 200 and a suction mechanism 300, and the gas stove 200 and the suction mechanism 300 are arranged on the upper surface of the stove body 100. The gas stove 200 includes a burner 210 for heating the pot 020. Optionally, the burner 210 heats the pot 020 by burning natural gas or liquefied gas. The gas stove 200 may include one or more burners 210. When multiple burners 210 are included, the gas stove 200 can heat multiple pots 020 at the same time. In this embodiment, the gas stove 200 includes two burners 210.
[0040] Furthermore, the gas stove 200 further includes a pot rack 220 for supporting the pot 020 . The pot rack 220 is disposed around the burner 210 . When the pot rack 220 supports the bottom of the pot 020 , the pot 020 is located above the burner 210 .
[0041] Furthermore, the gas stove 200 also includes an energy focusing ring 230 arranged on the pot rack 220, and the energy focusing ring 230 substantially coincides with the axis of the burner 210. The energy focusing ring 230 can reflect the heat radiated downward from the bottom of the pot 020 back to the bottom of the pot 020, thereby reducing heat loss and improving the thermal efficiency of the burner 210.
[0042] In the embodiment of the present application, the suction mechanism 300 is provided with a suction port 301 for absorbing oil smoke, and the suction port 301 is located above the burner 210 in the height direction. When cooking, the suction port 301 is also located above the pot 020. In this embodiment, the suction port 301 is located above the burner 210 and faces the horizontal direction; in other optional embodiments, the suction port 301 can also be located directly above the burner 210 and face vertically downward; of course, the suction mechanism 300 can also have the above two types of suction ports 301 at the same time. It should be understood that the suction mechanism 300 also includes a fan (not shown in the figure), and an air duct is formed in the suction mechanism 300. The fan generates negative pressure in the air duct, so that the suction port 301 can absorb the oil smoke above the pot 020. In this embodiment, the suction mechanism 300 further includes a smoke shield 330, which is disposed above the inhalation port 301. The smoke shield 330 extends horizontally toward the side where the burner 210 is located, thereby blocking the oil smoke. The smoke shield 330 can be fixed or flip-type; when the smoke shield 330 is flip-type, it can be rotated to a closed position to block the inhalation port 301.
[0043] In the embodiment of the present application, the suction mechanism 300 includes a heat shield 310, a driving assembly 311, and a detection device 312. In the embodiment of the present application, the heat shield 310 is spaced from the burner 210 in the horizontal direction, and is lower than the opening of the pot 020 on the burner 210 in the height direction. The driving assembly 311 is used to drive the heat shield 310 to approach or move away from the bottom of the pot 020 on the burner 210, and the detection device 312 is used to detect the distance between the heat shield 310 and the bottom of the pot 020 on the burner 210. It should be understood that in the present embodiment, the pot 020 has an inner side and an outer side, the inner side is used to place the cooked food, and the outer side of the pot 020 is the bottom of the pot 020, which is used to receive heat. In the embodiment of the present application, since the heat shield 310 can be driven by the driving assembly 311 to move closer to or farther away from the bottom of the pot 020 on the burner 210, the spacing distance between the pot 020 and the suction mechanism 300 can be adjusted by adjusting the position of the heat shield 310. On the one hand, the spacing distance can be kept small, thereby shrinking the channel between the pot 020 and the suction mechanism 300, reducing the heat lost upward through the channel between the pot 020 and the suction mechanism 300, and improving thermal efficiency; on the other hand, when the pot 020 moves, the position of the heat shield 310 can be adaptively adjusted to avoid a poor heat shielding effect due to an excessively large distance between the pot 020 and the heat shield 310; and also to avoid mutual interference due to an excessively small distance between the pot 020 and the heat shield 310.
[0044] In this embodiment, the heat shield 310 has a first end and a second end opposite to each other. The first end of the heat shield 310 is in transmission connection with the driving assembly 311. The driving assembly 311 is used to drive the heat shield 310 to flip around the rotation axis so that the second end of the heat shield 310 is close to or away from the bottom of the pot 020. In this embodiment, the rotation axis of the heat shield 310 extends in the horizontal direction. The two extreme positions of the heat shield 310 in its own rotation stroke are respectively a closed position and a maximum open position. When the heat shield 310 is in the closed position, the second end of the heat shield 310 is below the first end.
[0045] Figure 4 This is a schematic diagram of a heat shield 310 and a drive assembly 311 in a first viewing angle in an embodiment of the present application; Figure 5 Schematic diagram of a heat shield 310 and a drive assembly 311 in a second viewing angle in one embodiment of the present application. Figure 4 and Figure 5As shown, in the embodiment of the present application, the heat shield 310 can not only block the high-temperature air from flowing upward, so that more heat is kept under the pot 020, but also reflect the heat to the pot 020 to a certain extent. It can be understood that part of the heat of the pot 020 and the burner 210 is transmitted outward by radiation, and when the heat reaches the heat shield 310, it will be reflected. In this embodiment, the heat shield 310 has an inner side and an outer side facing each other, and the outer side is used to face the bottom of the pot 020. Figure 3 It can be seen that when the heat shield 310 is opened, the outer side of the heat shield 310 faces the bottom of the pot 020. In order to improve the heat reflection effect, in this embodiment, the outer side of the heat shield 310 is a wavy surface, and the wavy surface can reflect the heat in multiple directions, so that the outer surface (i.e., the bottom) of the pot 020 receives the heat reflected by the heat shield 310 more evenly. In other optional embodiments, the outer side of the heat shield 310 can also be a curved surface, and the curved surface can reflect the heat to the bottom of the pot 020 in a concentrated manner, thereby improving the efficiency of the heat shield 310 reflecting the heat to the pot 020. In order to improve the reflection efficiency, the baffle can be made of a high-reflection, low-absorption material, such as a smooth mirror surface on the outer surface of the heat shield 310.
[0046] In this embodiment, the detection device 312 includes a radar disposed on the heat shield 310, and the radar can effectively detect the distance between the heat shield 310 and the bottom of the pot 020 on the burner 210. The radar can be a laser radar, a millimeter wave radar, or an ultrasonic radar. In this embodiment, the radar is disposed on the side of the heat shield 310 that is away from the pot 020 (i.e., the inner side), and the detection signal of the radar can pass through the heat shield 310 to reach the bottom of the pot 020. Specifically, a hole can be set on the heat shield 310 so that the detection signal of the radar can pass through the heat shield 310 through the hole; or, the heat shield 310 is partially or entirely transparent, and the detection signal of the radar (such as a light signal) can pass through the transparent area; or, the heat shield 310 is partially or entirely made of wave-transmitting material, and the detection signal of the radar can pass through the wave-transmitting material area. In this embodiment, the heat shield 310 can be made of glass.
[0047] When the gas stove 200 has multiple burners 210, there may be multiple detection devices 312, and the multiple detection devices 312 correspond to the multiple burners 210 one by one. In this embodiment, two detection devices 312 are arranged on the heat shield 310, corresponding to the two burners 210 respectively.
[0048] The specific structure and setting method of the detection device 312 may not be limited to the above-mentioned method. For example, in other optional embodiments, the detection device 312 may be a camera, and the distance between the heat shield 310 and the bottom of the cookware 020 is obtained by performing image processing on the collected image.
[0049] In the embodiment of the present application, the suction mechanism 300 further includes a reflector 320, which is used to reflect heat to the burner 210 and / or the bottom of the pot 020 on the burner 210. In the present embodiment, the reflector 320 is arranged vertically, and in the height direction, the reflector 320 is located below the smoking port 301, and the reflective surface of the reflector 320 faces the burner 210 and the pot 020. In the present embodiment, the reflector 320 is provided with an avoidance hole 321, and the avoidance hole 321 is used to avoid the driving assembly 311. When the heat shield 310 is in the closed position, the heat shield 310 covers a portion of the reflective surface of the reflector 320 at the lower side. It should be understood that in other optional embodiments, the reflective plate 320 may also be arranged only below the rotation axis of the heat shield 310. When the heat shield 310 is in the closed position, the heat shield 310 completely covers the reflective surface of the reflective plate 320. When the heat shield 310 is opened, the heat shield 310 reduces the upward flow of hot air. At the same time, the reflective plate 320 is exposed, which can reflect back a part of the heat radiation emitted by the burner 210 and the cooker 020, thereby improving the thermal efficiency.
[0050] Figure 6 FIG. 3 is a functional schematic diagram of a heat shield 310 and a reflector 320 in one embodiment of the present application. Figure 6 As shown in the figure, the hollow arrow between the heat shield 310 and the pot 020 represents the heat lost upward from the channel between the heat shield 310 and the bottom of the pot 020, and the hollow arrow between the reflective plate 320 and the burner 210 represents the direction of heat radiation transfer between the burner 210 and the reflective plate 320.
[0051] In this embodiment, in order to improve the heat reflection efficiency, the reflection surface of the reflection plate 320 is a mirror surface. Specifically, the reflection plate 320 can be made of stainless steel, and a mirror reflection surface is formed by polishing; or the reflection plate 320 can also be a glass reflector. The reflection efficiency of the mirror to heat radiation is higher than that of ordinary stainless steel, and is significantly better than that of black-painted sheet metal.
[0052] Figure 7 FIG. 1 is a schematic diagram of a heat shield 310 in an embodiment of the present application when it is in the maximum open position. Figure 7 As shown, in this embodiment, when the heat shield 310 is at the maximum open position, the horizontal distance L2 and the vertical distance H2 between the second end and the closest point of the pot rack 220 are not less than 10 mm. By setting it in this way, the heat shield 310 and the pot rack 220 can maintain a safe distance, avoiding interference between the pot rack 220 or the pot 020 on the pot rack 220 and the heat shield 310.
[0053] In this embodiment, the integrated stove 010 further includes a controller (not shown in the figure), the detection device 312 and the driving assembly 311 are both electrically connected to the controller, and the controller is configured as follows:
[0054] After the burner 210 is started, the distance between the heat shield 310 and the bottom of the pot 020 on the burner 210 is obtained through the detection device 312; according to the relationship between the distance between the heat shield 310 and the bottom of the pot 020 on the burner 210 and the preset distance, the drive component 311 is controlled to drive the heat shield 310 to move so that the distance between the heat shield 310 and the bottom of the pot 020 on the burner 210 approaches the preset distance.
[0055] It can be understood that when the distance between the heat shield 310 and the bottom of the pot 020 on the burner 210 is a preset distance, the heat shield 310 can effectively prevent the heat from being lost upwards, and at the same time, the appropriate preset distance makes it difficult for the pot 020 to collide with the heat shield 310. Therefore, in this embodiment, the controller can adaptively adjust the distance between the heat shield 310 and the bottom of the pot 020 on the burner 210, so that the burner 210 can always maintain a high thermal efficiency, and at the same time, the heat shield 310 is not likely to interfere with the pot 020, which is convenient for the user's cooking operation.
[0056] The vertical distance between the upper side of the energy focusing ring 230 and the highest point of the pot support 220 is H1, and the distance H1 is designed to prevent the flame from burning the energy focusing ring 230 and ensure a safe distance for air circulation. Optionally, the preset distance is H1+set value, and the range of the set value is 0-30 mm.
[0057] For the control method of the controller of this embodiment, please refer to the introduction of the integrated stove control method below.
[0058] Figure 8 Flow chart of an integrated stove control method in one embodiment of the present application. The integrated stove control method provided in the embodiment of the present application can be applied to the integrated stove 010 provided in the above embodiment. Figure 8 As shown, the integrated stove control method includes the following steps:
[0059] Step S100 , after the burner 210 is started, the distance between the heat shield 310 and the bottom of the pot 020 on the burner 210 is obtained by the detection device 312 .
[0060] In the embodiment of the present application, the burner 210 can be started by the user manually pressing and twisting the knob. A sensor can be set in the integrated stove 010 to monitor whether the burner 210 is started. When it is determined that the burner 210 is started, the controller obtains the distance between the heat shield 310 and the bottom of the pot 020 on the burner 210 through the detection device 312.
[0061] In step S200, based on the relationship between the distance between the heat shield 310 and the bottom of the pot 020 on the burner 210 and the preset distance, the driving assembly 311 is controlled to drive the heat shield 310 to move so that the distance between the heat shield 310 and the pot 020 on the burner 210 approaches the preset distance.
[0062] In the embodiment of the present application, the distance between the upper side of the energy focusing ring 230 and the highest point of the pot rack 220 in the vertical direction is H1, the preset distance is H1+set value, and the range of the set value is 0 to 30 mm. For example, the set value is 0mm, 1mm, 3mm, 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, or a value between any two of the above points. By using a suitable preset distance, a large amount of hot air is prevented from flowing upward from the interval channel between the pot 020 and the heat shield 310 due to a too large preset distance, and it is also possible to prevent the pot 020 from colliding with the heat shield 310 due to a too small preset distance, thereby affecting the user's cooking operation.
[0063] Fig. 9 Schematic diagram of a pot 020 after it moves toward the suction mechanism 300 in one embodiment of the present application. Figure 7 and Fig. 9 The distance between the heat shield 310 and the bottom of the cookware 020 is L1, which may be the distance between the heat shield 310 and the nearest point of the bottom of the cookware 020, or the distance between the tangent line of the bottom of the cookware 020 parallel to the heat shield 310 and the plane where the heat shield 310 is located, or the distance between the detection device 312 and the cookware 020 in the detection direction. Fig. 9 The pot 020 in Figure 7 The pot 020 in the pot 020 moves a certain distance toward the suction mechanism 300. When the detection device 312 detects that the distance between the bottom of the pot 020 and the heat shield 310 is reduced, the driving assembly 311 controls the heat shield 310 to flip away from the pot 020 (i.e., the closed position), so that the distance L1 between the heat shield 310 and the bottom of the pot 020 remains at the preset distance. In this way, the distance between the pot 020 and the heat shield 310 will not be too small, thereby avoiding interference between the pot 020 and the shield.
[0064] It should be understood that, since the movement range of the heat shield 310 is limited, and the position of the pot 020 is relatively free, it is difficult for the heat shield 310 to maintain a preset distance from the bottom of the pot 020 in some cases (for example, when the pot 020 is too close to the suction mechanism 300 or too far away from the suction mechanism 300). Therefore, in an optional embodiment, step S200 specifically includes:
[0065] When the distance between the heat shield 310 and the bottom of the pot 020 on the burner 210 is greater than the preset distance and the heat shield 310 is not in the maximum open position, the control driving assembly 311 drives the heat shield 310 to rotate toward the maximum open position until the distance between the heat shield 310 and the bottom of the pot 020 on the burner 210 is equal to the preset distance or the heat shield 310 reaches the maximum open position;
[0066] When the distance between the heat shield 310 and the bottom of the pot 020 on the burner 210 is less than the preset distance and the heat shield 310 is not in the closed position, the control drive assembly 311 drives the heat shield 310 to rotate toward the closed position until the distance between the heat shield 310 and the bottom of the pot 020 on the burner 210 is equal to the preset distance or the heat shield 310 reaches the closed position.
[0067] It can be seen that through the above control method, the distance between the heat shield 310 and the bottom of the cookware 020 can be made as close to the preset distance as possible, that is, better thermal efficiency can be ensured as much as possible and interference between the cookware 020 and the heat shield 310 can be avoided.
[0068] In summary, the integrated stove 010 provided in the embodiment of the present application includes a stove body 100, a gas stove 200 and a suction mechanism 300 arranged on the stove body 100. The gas stove 200 includes a burner 210 for heating the pot 020. The suction mechanism 300 is provided with a suction port 301 for absorbing oil smoke, and the suction mechanism 300 includes a heat shield 310, a driving component 311 and a detection device 312. The driving component 311 is used to drive the heat shield 310 to approach or move away from the bottom of the pot 020 on the burner 210, and the detection device 312 is used to detect the distance between the heat shield 310 and the bottom of the pot 020 on the burner 210. The integrated stove 010 of the embodiment of the present application can detect the distance between the current heat shield 310 and the bottom of the pot 020 through the detection device 312. If the distance is too large, the heat of the burner 210 will easily flow upward from the space between the pot 020 and the heat shield 310, resulting in low thermal efficiency. Therefore, the driving component 311 can be controlled to adjust the distance according to the detected distance information, so that the distance between the heat shield 310 and the bottom of the pot 020 will not be too large, thereby improving the thermal efficiency of the burner 210. On the other hand, if the distance between the heat shield 310 and the bottom of the pot 020 is too small, although the thermal efficiency is improved, it is easy to cause interference between the pot 020 and the heat shield 310. Therefore, controlling the driving component 311 to adjust the distance can also prevent the pot 020 from colliding with the heat shield 310.
[0069] The integrated stove control method provided in the embodiment of the present application includes: after the burner 210 is started, the distance between the heat shield 310 and the bottom of the pot 020 on the burner 210 is obtained by the detection device 312; according to the relationship between the distance between the heat shield 310 and the bottom of the pot 020 on the burner 210 and the preset distance, the driving component 311 is controlled to drive the heat shield 310 to move so that the distance between the heat shield 310 and the pot 020 on the burner 210 approaches the preset distance. The integrated stove control method provided in the embodiment of the present application can ensure that the heat shield 310 and the pot 020 on the burner 210 maintain a suitable distance during the cooking process, thereby reducing the heat loss of the burner 210 and improving the thermal efficiency; on the other hand, it can avoid the pot 020 from colliding with the heat shield 310.
[0070] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
