Description

Technical Field

[0001] The present invention relates to the technical field of integrated stoves, and in particular to an automatic fire extinguishing method and an integrated stove. Background Art

[0002] When cooking with an integrated stove, if the oil pan catches fire and the flame is accidentally sucked into the air duct or fan volute, the situation will become particularly dangerous. Especially when a lot of oil stains accumulate inside the air duct and volute, the integrated stove is very likely to burn, and may even cause a gas explosion, posing a huge threat to the user's life safety and property.

[0003] The existing technical solution is to add a firewall (temperature sensor) in the air duct to detect the inhalation of flames, and shut down the power and gas source through the controller to achieve a certain degree of protection, but this method still has shortcomings. When the oil pan is still burning, if fire extinguishing measures are not taken in time, the fire may continue to spread, and a large amount of harmful gases will be produced, thus causing a greater safety accident.

[0004] Another method is to set a spray mechanism on the upper computer or other positions to spray the fire extinguishing medium when the oil pan catches fire. Although it can effectively extinguish the fire, it causes secondary pollution to the cooking process and kitchen hygiene. Summary of the invention

[0012] In an optional embodiment, the fire extinguishing device includes a storage box that is telescopically connected to the smoke baffle, and the fire extinguishing pot cover is accommodated in the storage box;

[0013] After the controller receives the fire extinguishing signal and cuts off the gas source and turns off the range hood, the controller first controls the storage box to extend out of the smoke baffle to a position directly above the stove head, and then releases the fire extinguishing pot cover.

[0014] In an optional embodiment, the fire extinguishing device includes a locking assembly that cooperates with the fire extinguishing pot cover; the locking assembly is electrically connected to the controller, and the locking assembly can lock or release the fire extinguishing pot cover;

[0015] After receiving the fire extinguishing signal, the controller sends a release signal to the locking component, and the locking component releases the fire extinguishing pot cover.

[0017] In an optional embodiment, after the controller receives a fire extinguishing signal, the locking assembly releases the fire extinguishing pot cover;

[0018] If the controller obtains that the state of the micro switch is connected, an alarm message is issued to remind the fire extinguisher lid to be lowered.

[0019] In an optional embodiment, after the controller receives a fire extinguishing signal, the locking assembly releases the fire extinguishing pot cover;

[0020] If the controller obtains that the state of the micro switch is disconnected, the controller compares the current detection value of the temperature sensor with a preset temperature threshold;

[0021] When the current detection value of the temperature sensor is greater than a preset temperature threshold, the controller issues an alarm message;

[0022] When the current detection value of the temperature sensor is less than a preset temperature threshold, the controller controls the range hood to turn on a high gear.

[0023] In an optional embodiment, after the fire extinguisher pot cover is manually placed into the storage box, the micro switch links the locking assembly to lock the fire extinguisher pot cover and send a locking signal;

[0024] After receiving the locking signal, the controller waits for a preset delay time and then controls the storage box to retract into the smoke baffle.

[0040] 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.

[0041] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0042] This embodiment provides an automatic fire extinguishing method for fire extinguishing control of a fire extinguishing device 10, which includes a fire extinguishing pot cover 200; smoke enters the range hood through the guidance of a smoke hood assembly 24 and a smoke baffle 23, and a temperature sensor 14 is provided on the smoke hood assembly 24 or the smoke baffle 23.

[0043] For further information, please refer to Figure 1 and Figure 2 The fire extinguishing device 10 of this embodiment includes a locking assembly 11, a rope 300 and a fire extinguishing pot cover 200. The locking assembly 11 is connected to the fire extinguishing pot cover 200 through the rope 300. During the fire extinguishing operation, the locking assembly 11 releases the fire extinguishing pot cover 200 so that the fire extinguishing pot cover 200 can fall into the pot 22 under the action of gravity, and when the fire extinguishing is completed, the rope 300 remains straightened so that the lower edge of the fire extinguishing pot cover 200 is against the pot 22.

[0044] Specifically, the fire extinguishing device 10 includes a storage box 100, and the fire extinguishing pot cover 200 is accommodated in the storage box 100. The storage box 100 is connected to the smoke baffle 23 through a retracting assembly 500, so that the storage box 100 can extend from the smoke baffle 23 to just above the stove head 21, or retract into the smoke baffle 23.

[0045] In an optional embodiment, the retracting assembly 500 includes a guide rail 510 and a driving mechanism, wherein the guide rail 510 is disposed on the smoke shield 23, and the storage box 100 is slidably matched with the guide rail 510; the fixed end of the telescopic mechanism 520 is connected to the smoke shield 23, and the telescopic end of the telescopic mechanism 520 is connected to the storage box 100 to drive the storage box 100 to move closer to or away from the smoke shield 23. Optionally, the driving mechanism is an electric push rod.

[0046] The bottom of the storage box 100 is provided with a receiving groove 110 with an opening facing downward, and the fire extinguishing pot cover 200 is arranged in the receiving groove 110 through a locking assembly 11. The locking assembly 11 is electrically connected to the controller, and the locking assembly 11 can lock or release the fire extinguishing pot cover 200.

[0047] In an optional embodiment, the locking assembly 11 can be an electromagnetic mechanism to lock or release the fire extinguishing pot cover 200 through magnetic attraction, or the locking assembly 11 can be an electric lock to lock or release the fire extinguishing pot cover 200 through the extension and retraction of the lock tongue.

[0048] When the storage box 100 is directly above the stove 21, the rope 300 includes a vertical section 320, one end of which is connected to the top of the fire extinguishing pot cover 200, and the other end extends to the center of the receiving groove 110; and the length of the vertical section 320 is less than the distance between the storage box 100 and the bottom of the pot 22 placed on the stove 21 in the vertical direction. In this way, the length of the rope 300 is equivalent to the distance between the receiving groove 110 and the bottom of the pot, so that the rope 300 can pull the fire extinguishing pot cover 200 to prevent the fire extinguishing pot cover 200 from impacting the pot 22 when it falls quickly, and avoid hot oil splashing and scalding the user.

[0049] Optionally, one end of the rope 300 away from the fire extinguishing pot cover 200 is arranged on the smoke baffle 23 through the stop block 13, and the rope 300 also includes a horizontal section 310 from the stop block 13 to the center of the receiving groove 110. One end of the horizontal section 310 of the rope 300 is connected to the stop block 13, and the other end of the horizontal section 310 passes through the central hole 111 of the receiving groove 110 and is connected to the fire extinguishing pot cover 200 through the vertical section 320.

[0050] In order to prevent the fire extinguishing pot cover 200 from impacting the pot 22 when falling rapidly, and to avoid hot oil splashing and scalding the user, the length of the rope 300 should meet the requirements: the distance of the vertical section 320 of the rope 300 is L2-L3.

[0051] Among them, L2 is the distance between the center of the receiving groove 110 and the vertical direction of the top of the stove head 21; L3 is the distance between the top of the stove head 21 and the lowest point of the fire extinguishing pot cover 200 after falling, that is, the safety distance; the distance of the vertical section 320 of the rope 300 is L2-L3. Setting the safety distance L3 can take into account that the fire extinguishing pot cover 200 can completely cover the pot 22, and can also avoid the impact of the fire extinguishing pot cover 200 on the bottom of the pot 22.

[0052] Furthermore, the total length L of the rope 300 is required to be: L=L1+L2-L3, wherein the length of the horizontal section 310 is L1, that is, the distance from the limit block 13 to the center of the receiving groove 110 of the rope 300.

[0053] The fire extinguishing device 10 includes a micro switch 12, which is in a normally open state; when the fire extinguishing pot cover 200 is manually placed in the storage box 100, the contact of the micro switch 12 is triggered, and the micro switch 12 is linked to the locking component 11 to lock the fire extinguishing pot cover 200.

[0054] See also Figure 3 , such an automatic fire extinguishing method at least comprises the following steps:

[0055] S100: When the current detection value of the temperature sensor 14 is greater than or equal to the preset temperature threshold, and the duration of the current detection value being greater than the preset temperature threshold is greater than or equal to the preset time threshold, a fire extinguishing signal is issued;

[0056] S200: The controller receives a fire extinguishing signal, cuts off the gas source and turns off the range hood, and releases the fire extinguishing pot cover 200 so that the fire extinguishing pot cover 200 falls freely into the pot 22 on the stove head 21.

[0057] In this way, the preset temperature threshold and the preset time threshold are combined to accurately detect the situation of the pot 22 catching fire, so as to ensure that the fire extinguishing pot cover 200 can complete the fire extinguishing operation in a timely and efficient manner. When the oil pan catches fire, the flames are sucked into the air duct, and the fire wall is greater than the preset temperature threshold and the preset time threshold, the fire extinguishing pot cover 200 is released. Under the action of gravity, the fire extinguishing pot cover 200 quickly falls and covers the burning oil pan, cutting off the contact between the combustibles and the air, so that the fire is quickly extinguished.

[0058] In an optional embodiment, step S100 also includes: after the range hood is turned on high gear, when the current detection value of the temperature sensor 14 is less than the preset temperature threshold, and the duration of the current detection value being less than the preset temperature threshold is greater than or equal to the preset time threshold, the controller issues a normal working indication.

[0059] It should be noted that step S200 includes S210: the controller receives a fire extinguishing signal, cuts off the gas source and turns off the range hood; S220: the controller first controls the storage box 100 to extend the smoke baffle 23 to a position directly above the stove head 21; S230: the controller releases the fire extinguishing pot cover 200.

[0060] Step S220 is as follows: after the controller receives the fire extinguishing signal and cuts off the gas source and turns off the range hood, the controller first controls the storage box 100 to extend the smoke baffle 23 to a position directly above the stove head 21, and then releases the fire extinguishing pot cover 200.

[0061] Step S230 is as follows: after receiving the fire extinguishing signal, the controller sends a release signal to the locking component 11, and the locking component 11 releases the fire extinguishing pot cover 200.

[0062] The automatic fire extinguishing method further includes step S400: the controller obtains the state of the micro switch 12 in real time. If the controller obtains that the state of the micro switch 12 is connected, an alarm message is issued to remind the fire extinguishing pot cover 200 of the lowering failure. The specific working principle is: the micro switch 12 is in a normally open state; when the fire extinguishing pot cover 200 is manually placed in the storage box 100, the contact of the micro switch 12 is triggered, and the micro switch 12 is linked to the locking component 11 to lock the fire extinguishing pot cover 200.

[0063] The automatic fire extinguishing method also includes step S500: after releasing the fire extinguishing pot cover 200, when the current detection value of the temperature sensor 14 is less than the preset temperature threshold, the range hood is turned on the strong gear.

[0064] Further, step S500 is: after the controller receives the fire extinguishing signal, the locking assembly 11 releases the fire extinguishing pot cover 200; if the controller obtains that the state of the micro switch 12 is disconnected, the controller compares the current detection value of the temperature sensor 14 with the preset temperature threshold;

[0065] When the current detection value of the temperature sensor 14 is greater than the preset temperature threshold, the controller issues an alarm message;

[0066] When the current detection value of the temperature sensor 14 is less than the preset temperature threshold, the controller controls the range hood to turn on the high gear.

[0067] The automatic fire extinguishing method further includes step S600: after manually placing the fire extinguishing pot cover 200 into the storage box 100, the micro switch 12 links the locking assembly 11 to lock the fire extinguishing pot cover 200 and send a locking signal; after receiving the locking signal, the controller waits for a preset delay time and then controls the storage box 100 to retract into the smoke baffle 23. In this way, the storage box 100 can be stably stored.

[0068] In a second aspect, the present invention provides an integrated stove 20, which includes a smoke hood assembly 24, a smoke baffle 23, a range hood, a stove, and a fire extinguishing device 10;

[0069] The smoke hood assembly 24 is located on one side of the stove, the smoke shield is located above the stove, and the fire extinguishing device 10 is connected to the smoke shield 23; the pot 22 on the stove head 21 of the stove generates smoke when cooking, and the smoke enters the range hood through the guidance of the smoke hood assembly 24 and the smoke shield 23; the smoke hood assembly 24 or the smoke shield 23 is provided with a temperature sensor 14; the fire extinguishing device 10 includes a locking assembly 11, a rope 300 and a fire extinguishing pot cover 200, and the locking assembly 11 is connected to the fire extinguishing pot cover 200 through the rope 300;

[0070] During the fire extinguishing operation, the locking assembly 11 releases the fire extinguishing pot cover 200 so that the fire extinguishing pot cover 200 can fall into the pot 22 under the action of gravity, and when the fire extinguishing is completed, the rope 300 is kept straightened so that the lower edge of the fire extinguishing pot cover 200 abuts against the pot 22;

[0071] The fire extinguishing device 10 is controlled by the automatic fire extinguishing method as in any one of the aforementioned embodiments.

[0072] In summary, the embodiment of the present invention provides an automatic fire extinguishing method and an integrated stove 20, which have at least the following advantages:

[0073] 1. When the oil pan catches fire, the fire extinguishing pot cover 200 falls down, quickly covers the burning oil pan, cuts off the contact between the fire source and the air, and extinguishes the fire quickly without affecting the cooking environment.

[0074] 2. A temperature sensor 14 is provided at the bottom of the smoke collecting hood or on the smoke baffle 23 to determine whether the oil pan is on fire according to a preset temperature threshold and a preset time threshold.

[0075] 3. After the fire is extinguished, the range hood will run at high speed to quickly exhaust harmful gases and improve the air quality in the kitchen.

[0076] 4. Combined with the fire protection threshold, the state of the micro switch 12 is detected to determine whether the fire extinguishing pot cover 200 has effectively fallen off. If it is abnormal, an alarm reminder can be issued.

[0077] 5. The length of the rope 300 is defined to prevent the fire extinguisher cover 200 from impacting the pot 22 when falling rapidly, thereby preventing hot oil from splashing and scalding the user.

[0078] 6. The locking assembly 11 cooperates with the micro switch 12 to keep the fire extinguisher cover 200 below the accommodating groove 110 of the storage box 100.

[0079] The above are only specific embodiments of the present invention, but the protection scope of the present invention 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 by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
