When the temperature sensor detects that the pot is dry-burned, the stove can activate the protection mechanism and then extinguish the flame of the stove to prevent safety problems.
[0003] Since the temperature probe detects the temperature of the cookware, the cookware needs to be placed on the stove to ensure that the temperature probe can accurately detect the temperature of the cookware. When the user briefly removes the cookware for cleaning, the flame changes from the original tendency of burning the bottom of the pot and the flame going outward to a state where the flame is facing upward and melting. The high temperature of the flame is quickly transmitted to the temperature probe, causing the temperature of the temperature probe to quickly rise to above the safe temperature, thereby activating the anti-dry burning function of the stove.

DETAILED DESCRIPTION
[0061] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiment of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application. The embodiments of the present application are described in detail below in conjunction with the drawings.
[0062] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, or it can be an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0063] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are orientations or positional relationships based on the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.
[0064] The terms "first", "second", "third" (if any) in the specification and claims of this application and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.
[0065] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or display comprising a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or display.
[0066] In the related art, the stove is equipped with an anti-dry burning function, that is, the stove can be provided with a temperature sensor, which can detect whether the pot is dry-burned by detecting the temperature of the pot. When the temperature sensor detects that the pot is dry-burned, the stove can activate the protection mechanism and then extinguish the flame of the stove to prevent safety problems.
[0067] Since the temperature probe detects the temperature of the pot, the pot needs to be placed on the stove to ensure that the temperature probe can accurately detect the temperature of the pot. When the temperature of the pot rises above the safe temperature due to a long dry burning time, the temperature of the pot is transmitted to the temperature probe, and the anti-dry burning function is correctly activated. When the user briefly removes the pot for cleaning, the flame changes from the original tendency of burning the bottom of the pot and the flame outward to the state of the flame facing upward and melting. The high temperature of the flame is quickly transmitted to the temperature probe, which causes the temperature of the temperature probe to quickly rise above the safe temperature, causing the stove to mistakenly activate the anti-dry burning function. At this time, the pot has not been dry burned, and the user is also on site.
[0068] However, after washing the pot, the user still needs to continue cooking. Since the anti-dry-burn function is mistakenly triggered and causes the fire to go out, the user needs to reignite the fire, which results in a poor user experience.
[0069] In view of this, an embodiment of the present application provides a stove and a control method thereof. The stove is linked to a temperature detection component by setting an electric switch. The controller can determine whether the pot is temporarily removed by the closing time and the opening time of the electric switch. When the pot leaves the stove temporarily, the controller can control the fan assembly to blow air into the through hole, thereby lowering the temperature of the temperature detection component, thereby avoiding the temperature of the temperature detection component being too high and erroneously triggering the anti-dry burning function of the stove, thereby improving the user's experience.
[0070] The following combination Figures 1 to 18 The specific implementation of the stove and the control method thereof provided in the embodiment of the present application is described in detail.
[0071] Reference Figures 1 to 13 As shown, the stove of the embodiment of the present application may include an ignition divider 100, a temperature detection component 200, an electric switch 300, a fan component 400 and a controller. The ignition divider 100 has a through hole 110 at the center. The fan component 400 is connected to the through hole 110 and is constructed to blow air toward the through hole 110.
[0072] The temperature detection assembly 200 includes a support tube 210 and a temperature detection member 220. The support tube 210 is movably inserted into the through hole 110. The temperature detection member 220 is connected to one end of the support tube 210. The temperature detection member 220 is configured to detect the temperature of the cookware.
[0073] When one end of the support tube 210 away from the temperature detection member 220 abuts against the electric switch member 300, the electric switch member 300 is closed, and when one end of the support tube 210 away from the temperature detection member 220 is no longer abutted against the electric switch member 300, the electric switch member 300 is disconnected. Both the temperature detection member 220 and the electric switch member 300 are conductively connected to the controller, and the controller is configured to control the start and stop of the fan assembly 400.
[0074] In this embodiment, the igniter 100 is used for secondary mixing of air and fuel gas, so that the mixed gas is ignited under the action of the igniter, and the through hole 110 is used for installing the temperature detection component 200.
[0075] The temperature detection component 200 is used to detect the temperature of the cookware and feed back the temperature signal of the cookware to the controller for analysis and decision-making by the controller. The temperature detection component 220 is used to detect the temperature of the cookware, and the support tube 210 is used to install the temperature detection component 220 into the through hole 110.
[0076] The electric switch 300 and the temperature detection assembly 200 cooperate to detect whether the pot is temporarily removed from the cooker. The electric switch 300 may be a micro switch, and may include a contact piece 310, a push switch 320, and a contact point. The temperature detection assembly 200 may abut against the contact piece 310, thereby driving the contact piece 310 to contact the push switch 320, so that the contact point is in a closed state, thereby making the circuit of the electric switch 300 conductive. Alternatively, the temperature detection assembly 200 may be disengaged from the contact piece 310, thereby making the contact piece 310 disengaged from the push switch 320, so that the contact point is in an open state, thereby making the circuit of the electric switch 300 disconnected.
[0077] For example, the temperature detection component 220 can adopt a contact temperature sensor. When the cooker is placed on the stove, the temperature detection component 220 can directly contact the cooker to detect the temperature of the cooker, and the cooker has a downward pressure on the temperature detection component 220, which can cause the support tube 210 to move downward, and then cause the end of the support tube 210 away from the temperature detection component 220 to abut against the electric switch component 300, thereby closing the electric switch component 300.
[0078] If the cooker is removed from the cooker, the cooker loses contact with the temperature sensing component 220, and the pressure exerted by the cooker on the temperature sensing component 220 disappears, causing the temperature sensing component 220 and the support tube 210 to move upward together, causing the end of the support tube 210 that is away from the temperature sensing component 220 to lose contact with the electrical switch component 300, thereby disconnecting the electrical switch component 300.
[0079] At this time, the controller can receive the disconnection signal of the electric switch 300. When the electric switch 300 is disconnected for a period of time and then closed again within a period of time, it means that the pot is temporarily removed from the stove. The controller can control the fan assembly 400 to open, and then blow air into the through hole 110 through the blowing assembly to reduce the temperature of the temperature detection member 220, thereby preventing the temperature of the temperature detection member 220 from being too high and erroneously triggering the anti-dry-burning function. When the user washes the pot and puts the pot on the stove again to cook, the controller can receive the closing signal of the electric switch 300, and the controller can control the fan assembly 400 to close.
[0080] For another example, the temperature detection member 220 may be a non-contact temperature sensor or an electromagnetic induction temperature sensor. When the cooker is placed on the stove, the top of the support tube 210 may contact the cooker, and the cooker exerts a downward pressure on the support tube 210. If the cooker is removed from the stove, the cooker and the support tube 210 are out of contact, and the pressure exerted by the cooker on the support tube 210 disappears, and the temperature detection member 220 and the support tube 210 move upward together, and the end of the support tube 210 away from the temperature detection member 220 is out of contact with the electric switch 300, and the electric switch 300 is disconnected.
[0081] When the electric switch 300 is disconnected for a period of time and then closed again within a period of time, it means that the pot is temporarily removed from the stove. At this time, the controller can control the fan assembly 400 to open, and then blow air into the through hole 110 through the blowing assembly to reduce the temperature of the temperature detection member 220, thereby preventing the temperature of the temperature detection member 220 from being too high and erroneously triggering the anti-dry-burning function. When the user washes the pot and puts the pot on the stove again to cook, the controller can control the fan assembly 400 to close.
[0082] The stove of this embodiment includes an ignition distributor 100 , a temperature detection assembly 200 , an electric switch 300 , a fan assembly 400 and a controller. The ignition distributor 100 includes a through hole 110 , and the temperature detection assembly 200 includes a support tube 210 and a temperature detection member 220 . By setting a through hole 110 for installing a support tube 210 and a temperature detection component 220, by setting a support tube 210 for installing the temperature detection component 220 into the through hole 110, by setting the temperature detection component 220 for detecting the temperature of the cookware and transmitting the temperature signal to the controller, by setting a fan assembly 400 for blowing air toward the through hole 110, thereby lowering the temperature of the temperature detection component 220, and by setting an electric switch component 300 for cooperating with the temperature detection component 220 or the support tube 210, thereby sensing whether the cookware is removed from the stove, when the cookware is removed from the stove, the controller can obtain a disconnection signal from the electric switch component 300, thereby enabling the controller to control the fan assembly 400 to blow air toward the through hole 110, thereby preventing the flame from concentrating on heating the temperature detection component 220 when the cookware is removed, causing the temperature to be too high and erroneously triggering the anti-dry-burning function.
[0083] Reference Figures 7 to 9 As shown, in some embodiments, the temperature detection assembly 200 further includes a trigger member 230 , which is connected to one end of the support tube 210 away from the temperature detection member 220 , and the trigger member 230 is constructed to abut or disengage from the electrical switch member 300 .
[0084] With such arrangement, the contact area between the trigger member 230 and the electric switch member 300 is larger, and the trigger member 230 can improve the degree of coordination with the electric switch member 300, so that when the cooker is placed on the cooker, the support tube 210 can drive the trigger member 230 to accurately abut against the electric switch member 300, thereby improving the accuracy of triggering the electric switch member 300.
[0085] It can be understood that the temperature detection component 200 can also include a wire 240, and the temperature detection component 220 can be conductively connected to the controller through the wire 240, and then the temperature signal is transmitted to the controller through the wire 240. The wire 240 can be passed through the support tube 210, and then the wire 240 is protected by the support tube 210.
[0086] Reference Figures 14 to 17 As shown, in a possible implementation, the cooker further includes a nozzle member 500 , the nozzle member 500 has an air blowing channel 510 , the air blowing channel 510 has an air inlet 520 and an air outlet 530 , the air outlet 530 is connected to the through hole 110 , and the air inlet 520 is connected to the fan assembly 400 .
[0087] It is understandable that the ignition distributor 100 can be connected to the nozzle member 500, and the gas and air can be mixed once through the nozzle member 500 and then mixed a second time through the ignition distributor 100, so that the gas can be fully burned.
[0088] In this embodiment, a blowing channel 510 is provided in the nozzle member 500, and an air inlet 520 and an air outlet 530 are provided at both ends of the blowing channel 510, so that the two ends of the blowing channel 510 are respectively connected to the through hole 110 and the fan assembly 400, so that the cold air blown out by the fan assembly 400 flows along the blowing channel 510 and the through hole 110 in sequence, thereby effectively reducing the temperature of the temperature detection member 220.
[0089] Reference Figure 1 and Figure 2 As shown, in some embodiments, the cooker further includes a bottom plate 600 and a panel connected to each other, the bottom plate 600 and the panel define a receiving cavity, the electric switch component 300, the fan assembly 400 and the nozzle component 500 are all located in the receiving cavity, and the electric switch component 300, the fan assembly 400 and the nozzle component 500 are all connected to the bottom plate 600, the flame distributor 100 is connected to the nozzle component 500, and the flame distributor 100 is located on a side of the panel away from the bottom plate 600. The side of the panel away from the bottom plate 600 constitutes a countertop.
[0090] In this way, the electric switch member 300, the fan assembly 400 and the nozzle member 500 can be hidden in the accommodating cavity and fixed on the bottom plate 600, while the flame distributor 100 can be exposed on the table so that the flame distributor 100 provides flame to the pot.
[0091] Reference Figures 6 to 9 As shown, in some embodiments, the support tube 210 includes a first tube segment 211 and a second tube segment 212 connected in sequence, the first tube segment 211 is consistent with the extension direction of the through hole 110, the second tube segment 212 is set at an angle to the extension direction of the through hole 110, and the temperature detection component 220 is set at the end of the first tube segment 211 away from the second tube segment 212, and the end of the second tube segment 212 away from the first tube segment 211 is in contact with or out of contact with the electrical switch component 300.
[0092] It is understandable that when the cooker is correctly installed, within the tolerance range, the through hole 110 extends in the vertical direction, and the panel is arranged parallel to the horizontal plane. When the support tube 210 is divided into the first tube section 211 and the second tube section 212, the first tube section 211 can extend in the vertical direction, so that the cooker generates a downward pressure force on the temperature detection member 220 or the first tube section 211, so that the support tube 210 abuts against the electric switch member 300 to close the electric switch member 300. The second tube section 212 can extend in the horizontal direction, so that the extension dimension of the support tube 210 in the vertical direction is reduced, thereby reducing the extension dimension of the cooker in the vertical direction.
[0093] Reference Figure 6 , Fig.17 As shown, in some embodiments, the blowing channel 510 includes a first channel 511 and a second channel 512 which are connected in sequence, the extension direction of the first channel 511 is consistent with the extension direction of the through hole 110, and the end of the first channel 511 away from the second channel 512 constitutes an air outlet 530, the extension direction of the second channel 512 is set at an angle to the extension direction of the through hole 110, and the end of the second channel 512 away from the first channel 511 constitutes an air inlet 520.
[0094] That is, the first channel 511 can extend in the vertical direction, so that when the cold air provided by the fan assembly 400 flows into the first channel 511, it can be blown toward the through hole 110 in the vertical direction, and then enter the gap between the support tube 210 and the through hole 110, so as to cool the temperature detection member 220. The second channel 512 can extend in the horizontal direction, so that the fan assembly 400 can be arranged in the free space on the side of the nozzle member 500, rather than below, which will reduce the extension size of the cooker in the vertical direction, thereby making the overall structure of the cooker more compact.
[0095] On the basis of the above embodiments, the embodiment of the present application further provides a control method of a stove, which is applied to the stove, wherein the stove includes a ignition distributor 100, a temperature detection assembly 200, an electric switch 300, a fan assembly 400 and a controller, the ignition distributor 100 has a through hole 110 at its center, the temperature detection assembly 200 includes a support tube 210 and a temperature detection member 220, the support tube 210 is movably inserted in the through hole 110, the temperature detection member 220 is connected to one end of the support tube 210, and the temperature detection member 220 is configured to detect the temperature of the pot. The electric switch member 300 includes the electric switch member 300, when one end of the support tube 210 away from the temperature detection member 220 abuts against the electric switch member 300, the electric switch member 300 is closed, and when one side of the support tube 210 away from the temperature detection member 220 is disengaged from the abutment with the electric switch member 300, the electric switch member 300 is disconnected. The fan assembly 400 is connected to the through hole 110 and is configured to blow air toward the through hole 110. The temperature detection element 220 and the electric switch element 300 are both electrically connected to the controller, and the controller is configured to control the start and stop of the fan assembly 400 .
[0096] Reference Fig.18 As shown, specifically, the control method includes:
[0097] S101, obtaining the disconnection time t1 of the electric switch element 300, and obtaining the first detection temperature T1 of the temperature detection element 220;
[0098] S102: If the first detected temperature T1 is equal to the first temperature threshold T max Satisfy: T1 ≥ T max , and the disconnection time t1 is equal to the first time threshold t min Satisfies: t1 ≥ t min , the fan assembly 400 is controlled to turn on.
[0099] It should be noted that when the user flips the pot, the temperature detection element 220 is temporarily separated from the pot, which causes the electric switch 300 to be temporarily disconnected for a period of time, such as 2 to 3 seconds. At this time, the cooker still needs a larger flame to heat the pot. If the fan assembly 400 is turned on to blow air to the through hole 110, the temperature of the flame may be reduced, resulting in poor cooking effect. Therefore, when the disconnection time t1 of the electric switch 300 is less than t min When the cooker is basically placed on the cooker, the fan assembly 400 can be controlled to stop.
[0100] When the disconnection time t1 is equal to the first time threshold t min Satisfies: t1 ≥ t min , and the first detection temperature T1 and the first temperature threshold T max Satisfy: T1 ≥ T max, it means that the pot has been away from the stove for a certain period of time, and the flame concentrates on heating the temperature detection element 220, resulting in a higher first detection temperature T1. At this time, the fan assembly 400 can be controlled to open to blow air to the temperature detection element 220 through the through hole 110 to cool it down, thereby preventing the temperature of the temperature detection element 220 from continuing to rise and erroneously triggering the anti-dry burning function.
[0101] For example, t min It can be 3 seconds, T max It can be 260°C.
[0102] Reference Fig.19 As shown, in a possible implementation, S102, if the first detected temperature T1 is greater than the first temperature threshold T max Satisfy: T1 ≥ T max , and the disconnection time t1 is equal to the first time threshold t min Satisfies: t1 ≥ t min , then the fan assembly 400 is controlled to start, and then the following steps are further included:
[0103] S103 , obtaining the second detected temperature T2 of the temperature detecting element 220 again after the time interval t2 .
[0104] S1031, if the second detected temperature T2 is greater than the second temperature threshold T min Satisfy: T2 ≥ T min , the fan assembly 400 is controlled to continue to be turned on until the second detected temperature T2 is less than the second temperature threshold T min .
[0105] S1032: If the second detected temperature T2 is equal to the second temperature threshold T min Satisfy: T2<T min , the fan assembly 400 is controlled to shut down.
[0106] That is to say, when the cooker is away from the stove for a certain period of time and the flame concentrates on heating the temperature detection element 220, the fan assembly 400 is turned on to blow air to cool the temperature detection element 220. After the first time interval t2, it is necessary to check whether the temperature of the temperature detection element 220 has dropped.
[0107] When the second detected temperature T2 is still greater than or equal to the second temperature threshold T min When the temperature of the temperature detection element 220 is still relatively high, it is necessary to continue to use the fan assembly 400 to blow air to cool the temperature detection element 220.
[0108] After the second time interval t2, the second detected temperature T2 of the temperature detection element 220 can be continuously obtained. If the second detected temperature T2 is still greater than or equal to the second temperature threshold T min, indicating that the temperature of the temperature detection element 220 is still high, the fan assembly 400 is turned on to cool the temperature detection element 220 until the second detection temperature T2 is equal to the second temperature threshold T min Satisfy: T2<T min , indicating that the temperature of the temperature detection component 220 has dropped, and the fan assembly 400 is controlled to shut down.
[0109] For example, T min It can be 200°C.
[0110] Reference Fig. 20 As shown, in a possible implementation, S102, if the first detected temperature T1 is greater than the first temperature threshold T max Satisfy: T1 ≥ T max , and the disconnection time t1 is equal to the first time threshold t min Satisfies: t1 ≥ t min , then the fan assembly 400 is controlled to start, and then the following steps are further included:
[0111] S104: If the disconnection time t1 is equal to the second time threshold t max Satisfies: t1≤t max , the fan assembly 400 is controlled to shut down.
[0112] That is to say, if the disconnection time t1 satisfies: t min ≤t1≤t max , it means that the time when the pot leaves the stove reaches the first time threshold t min , and the pot is at the second time threshold t max The cooker is then placed on the cooker again, and during the time when the cooker is away, the temperature of the temperature detection member 220 exceeds the first temperature threshold value T max Therefore, during the time when the cooker is away, the fan assembly 400 can be turned on to blow air to cool down the temperature detection element 220, thereby preventing the flame from concentrating on heating the temperature detection element 220 and causing the anti-dry burning function to be triggered erroneously when the cooker is away for a short time. When the cooker is placed on the stove again, the fan assembly 400 can be turned off, so that the temperature detection element 220 can accurately detect the temperature of the cooker and avoid blowing air to lower the temperature of the flame.
[0113] For example, t max It can be 5 minutes.
[0114] Reference Fig.21 As shown, in a possible implementation, the stove further includes a control valve, and the control valve is configured to control the on-off state of the ignition distributor 100 and the gas pipeline.
[0115] S105, obtaining the disconnection time t1 of the electric switch 300, and obtaining the first detection temperature T1 of the temperature detection element 220, and then further comprising:
[0116] If the first detection temperature T1 and the first temperature threshold T max Satisfy: T1 ≥ T max , and the disconnection time t1 is equal to the first time threshold t min Satisfies: t1<t min , the control valve is closed.
[0117] It can be understood that when the disconnection time t1 is equal to the first time threshold t min Satisfies: t1<t min When the first detected temperature T1 is equal to the first temperature threshold T max Satisfy: T1 ≥ T max When the cooker is dry-burned, it is necessary to cut off the gas supply to prevent the flame from continuing to heat the cooker and causing safety problems. Therefore, the flame can be extinguished by closing the control valve between the ignition distributor 100 and the gas pipeline, thereby improving the safety of the cooker.
