Description

Technical Field

[0001] The present invention relates to the technical field of integrated stoves, and in particular to a fire extinguishing control 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 temperature sensor (temperature sensor) in the air duct to detect the inhalation of the flame, and shut down the power supply 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] The controller receives the fire extinguishing signal, cuts off the gas source and turns off the range hood, and the motor mechanism reverses to release the rope to allow the fire extinguishing pot cover to fall into the pot.

[0013] In an optional embodiment, when the current detection value of the temperature sensor is less than a preset temperature threshold, and the duration of the current detection value being less than the preset temperature threshold is greater than or equal to a preset time threshold, the controller issues a normal working indication.

[0014] 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;

[0019] In an optional embodiment, the controller is set with a preset descent time;

[0020] After the controller receives the fire extinguishing signal, the rotating motor is ready to release the fire extinguishing pot cover;

[0021] The controller controls the rotating motor to quickly reverse within a preset speed-drop time to release the rope, thereby causing the fire extinguisher cover to fall quickly.

[0022] In an optional embodiment, after the controller receives a fire extinguishing signal, the rotating motor releases the fire extinguishing pot cover;

[0023] When the working current is less than the rated current of the rotating motor, the controller controls the rotating motor to stop working, and the controller compares the current detection value of the temperature sensor with a preset temperature threshold;

[0024] When the current detection value of the temperature sensor is greater than a preset temperature threshold, the controller issues an alarm message;

[0025] 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.

[0026] In an optional embodiment, a reset button electrically connected to the controller is provided on the integrated stove;

[0027] When the range hood is turned on the high gear, the reset button is clicked to send a reset signal. After the controller receives the reset signal, the controller controls the rotating motor to rotate forward to tighten the rope to lift and retract the fire extinguisher cover.

[0032] If the rotating motor reaches a preset stall current, the controller controls the retracting assembly to retract into the smoke baffle;

[0033] If the operating current of the rotating motor is less than the rated current of the rotating motor, or the operating current of the rotating motor is zero, or the operating current of the rotating motor cannot reach the preset stall current within a preset time, the controller issues an alarm message.

[0034] In a second aspect, the present invention provides an integrated stove, which includes a smoke hood assembly, a smoke baffle, a range hood, a stove, and a fire extinguishing device;

[0035] The smoke hood assembly is located on one side of the stove, the smoke shield is located above the stove, and the fire extinguishing device is connected to the smoke shield; the pot on the stove head of the stove generates smoke when cooking, and the smoke is guided into the range hood through the smoke hood assembly and the smoke shield; a temperature sensor is arranged on the smoke hood assembly or the smoke shield;

[0038] The beneficial effects of the embodiments of the present invention include, for example:

[0039] Such a fire extinguishing control method can release the fire extinguishing pot cover by reversing the motor mechanism when the oil pan is on fire and the flames are sucked into the air duct, and the temperature sensor is greater than the preset temperature threshold and the preset time threshold. Under the action of gravity, the fire extinguishing pot cover quickly falls and covers the burning oil pan, cutting off the contact between the combustible material and the air, so that the fire is quickly extinguished. On the one hand, such an automatic fire extinguishing method does not affect the cooking environment. On the other hand, it determines whether the oil pan is on fire according to the temperature threshold and the time threshold, and the fire extinguishing timing is more accurate and reliable. At the same time, the rope is tightened by the forward rotation of the motor mechanism to lift and store the fire extinguishing pot cover. Such a fire extinguishing control method is simple to operate, easy to use, has a good fire extinguishing effect, and is not easy to produce secondary pollution. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] 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.

[0050] 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.

[0051] Please refer to Figure 1 and Figure 2 The present embodiment provides a fire extinguishing control method for controlling the fire extinguishing of a fire extinguishing device 10, wherein the fire extinguishing device 10 includes a fire extinguishing pot cover 210, a rope 300, and a motor mechanism 230. The smoke enters the hood through the guidance of the smoke collecting hood assembly 24 and the smoke baffle 23, and a temperature sensor 14 is provided on the smoke collecting hood assembly 24 or the smoke baffle 23.

[0052] For further information, please refer to Figure 1 and Figure 2One end of the rope 300 of the fire extinguishing device 10 of this embodiment is connected to the fire extinguishing pot cover 210, and the other end is connected to the rotor of the motor mechanism 230; the motor mechanism 230 is configured to rotate forward to tighten the rope 300 to lift the fire extinguishing pot cover 210, or to release the rope 300 in the reverse direction to allow the fire extinguishing pot cover 210 to fall to the pot 22 on the stove 21.

[0053] Specifically, the fire extinguishing device 10 includes a storage box 110, and the fire extinguishing pot cover 210 is accommodated in the storage box 110. The storage box 110 is connected to the smoke baffle 23 through a retracting assembly 500, so that the storage box 110 can extend from the smoke baffle 23 to just above the stove head 21, or retract into the smoke baffle 23.

[0054] In an optional embodiment, the retracting assembly 500 includes a guide rail 510 and a driving mechanism 520, wherein the guide rail 510 is disposed on the smoke shield 23, and the storage box 110 is slidably matched with the guide rail 510; the fixed end of the telescopic mechanism is connected to the smoke shield 23, and the telescopic end of the telescopic mechanism is connected to the storage box 110 to drive the storage box 110 to move closer to or away from the smoke shield 23. Optionally, the driving mechanism 520 is an electric push rod.

[0055] The motor mechanism 230 is a rotary motor, and the rope 300 is tightened or released by the forward and reverse rotation of the rotary motor.

[0056] The bottom of the storage box 110 is provided with a accommodating groove 111 with an opening facing downward, and the fire extinguisher cover 210 can be accommodated in the accommodating groove 111 through a rotating motor.

[0057] When the storage box 110 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 210, and the other end extends to the center of the receiving groove 111; and the length of the vertical section 320 is less than the distance between the storage box 110 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 111 and the bottom of the pot, so that the rope 300 can pull the fire extinguishing pot cover 210 to prevent the fire extinguishing pot cover 210 from impacting the pot 22 when it falls quickly, and avoid hot oil splashing and scalding the user.

[0058] Optionally, the motor mechanism 230 is arranged on the smoke baffle 23, and the storage box 110 assembly is connected to the smoke baffle 23; one end of the rope 300 is connected to the motor mechanism 230, and the other end passes through the center hole 112 of the accommodating groove 111 directly above the stove head 21 and is connected to the fire extinguisher cover 210; the rope 300 also includes a horizontal section 310 from the motor mechanism 230 to the center of the accommodating groove 111.

[0059] In order to prevent the fire extinguishing pot cover 210 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.

[0060] Among them, L2 is the distance between the center of the receiving groove 111 and the top of the stove head 21 in the vertical direction; L3 is the distance between the top of the stove head 21 and the lowest point of the fire extinguishing pot cover 210 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 210 can completely cover the pot 22, and can also prevent the fire extinguishing pot cover 210 from impacting the bottom of the pot 22.

[0061] 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.

[0062] In order to quickly extinguish the fire, a fast descending distance L4 is set. The length value of L4 is less than the length value of L2. Within the stroke of L4, the rotating motor runs at n times (n is a natural number greater than or equal to 1) the normal speed to shorten the descending time of the fire extinguishing pot cover 210.

[0063] The rapid descent distance L4 can be converted into a preset rapid descent time for the rapid operation of the rotary motor according to the rated speed of the rotary motor, the length of L4 and the set value of n times. That is, the rotary motor starts to work, rotates rapidly within the preset rapid descent time, and works at a normal speed after reaching the time threshold; when the working current is less than the rated current, it can be determined that the fire extinguishing pot cover 210 is in contact with the pot 22, and the rotary motor stops working.

[0064] See also Figure 3 , such an automatic fire extinguishing method at least comprises the following steps:

[0065] 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;

[0066] 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 210 so that the fire extinguishing pot cover 210 quickly falls into the pot 22 on the stove head 21.

[0067] In this way, when the oil pan catches fire and 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 rotating motor releases the fire extinguishing pot cover 210. The fire extinguishing pot cover 210 can cover the burning oil pan, cut off the contact between the combustible material and the air, and quickly extinguish the fire.

[0068] In an optional embodiment, step S100 further includes: 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 instruction. The preset temperature threshold and the preset time threshold are used to collaboratively determine whether the integrated stove 20 has completed fire extinguishing, thereby ensuring the fire extinguishing effect and preventing the fire from re-igniting.

[0069] 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 110 to extend the smoke baffle 23 to a position directly above the stove head 21; S230: the controller controls the rotating motor to release the fire extinguishing pot cover 210.

[0070] 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 110 to extend the smoke baffle 23 to a position directly above the stove head 21, and then releases the fire extinguishing pot cover 210.

[0071] Step S230 is as follows: after the controller receives the fire extinguishing signal, the rotating motor reverses to loosen the rope 300 to release the fire extinguishing pot cover 210 .

[0072] The automatic fire extinguishing method also includes step S300: after the controller receives the fire extinguishing signal, the motor mechanism 230 releases the fire extinguishing pot cover 210; the controller obtains the working current of the rotating motor, and when the working current is greater than or equal to the rated current of the rotating motor, an alarm message is issued to remind the rotating motor of a fault; when the working current is less than the rated current of the rotating motor, the controller controls the rotating motor to stop working.

[0073] In this way, the working current of the rotating motor is less than the rated current of the rotating motor to determine that the fire extinguishing pot cover 210 is in contact with the pot 22. This arrangement has a simple structure and reduces the number of components.

[0074] Step S300 also includes step S310: the controller is set with a preset descent time; after the controller receives the fire extinguishing signal, the rotating motor is ready to release the fire extinguishing pot cover 210; the controller controls the rotating motor to quickly reverse within the preset descent time to release the rope 300, so that the fire extinguishing pot cover 210 falls quickly.

[0075] This can shorten the descending time of the fire extinguishing pot cover 210, thereby improving the fire extinguishing efficiency.

[0076] The automatic fire extinguishing method also includes step S400: after the controller receives the fire extinguishing signal, the rotating motor releases the fire extinguishing pot cover 210; when the working current is less than the rated current of the rotating motor, the controller controls the rotating motor to stop working, and the controller compares the current detection value of the temperature sensor 14 with the preset temperature threshold; when the current detection value of the temperature sensor 14 is greater than the preset temperature threshold, the controller sends an alarm message; 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 strong gear.

[0077] In this way, by turning on the range hood at high speed, harmful gases can be quickly discharged and the air quality in the kitchen can be improved.

[0078] The automatic fire extinguishing method also includes step S500: after the controller receives the reset signal, the rotating motor rotates forward to tighten the rope 300 to lift and retract the fire extinguishing pot cover 210; if the rotating motor reaches the preset stall current, the controller controls the retraction assembly 500 to retract it into the smoke baffle 23; if the working current of the rotating motor is less than the rated current of the rotating motor, or the working current of the rotating motor is zero, or the working current of the rotating motor cannot reach the preset stall current within the preset time, the controller sends an alarm message.

[0079] By setting step S500, the current of the rotating motor can be used to determine whether the fire extinguishing pot cover 210 is reset to the specified position of the accommodating groove 111, which is conducive to ensuring that the fire extinguishing pot cover 210 can be stably received in the accommodating groove 111.

[0080] Further, step S500 may include step S510 or step S520.

[0081] Step S510: A reset button electrically connected to the controller is provided on the integrated stove 20; when the range hood is turned on the high gear, the reset button is clicked to send a reset signal, and after the controller receives the reset signal; the controller controls the rotating motor to rotate forward to tighten the rope 300 to lift and retract the fire extinguisher cover 210.

[0082] Step S520: The controller is set with a preset fire extinguishing safety time; when the range hood is turned on at a high gear and continues for the preset fire extinguishing safety time, the controller sends a reset signal to make the rotating motor rotate forward to tighten the rope 300 to lift and retract the fire extinguishing pot cover 210. In this setting, there is no need for a reset button for the fire extinguishing pot cover 210, and the fire extinguishing pot cover 210 can be automatically reset according to the combination of the preset temperature threshold of the temperature sensor 14 and the preset fire extinguishing safety time.

[0083] 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;

[0084] 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 is guided into the range hood through the smoke hood assembly 24 and the smoke shield 23; the temperature sensor 14 is provided on the smoke hood assembly 24 or the smoke shield 23;

[0085] The fire extinguishing device 10 includes a fire extinguishing pot cover 210, a rope 300 and a motor mechanism 230; one end of the rope 300 is connected to the fire extinguishing pot cover 210, and the other end is connected to the rotor of the motor mechanism 230; the motor mechanism 230 is configured to rotate forward to tighten the rope 300 to lift the fire extinguishing pot cover 210, or to rotate backward to release the rope 300 to make the fire extinguishing pot cover 210 fall;

[0086] The fire extinguishing device 10 is controlled by using the fire extinguishing control method as described in any of the above embodiments.

[0087] In summary, the embodiment of the present invention provides a fire extinguishing control method and an integrated stove 20, which have at least the following advantages:

[0088] 1. A fire extinguishing pot cover 210 is provided at the bottom of the storage box 110. When the oil pan catches fire, the fire extinguishing pot cover 210 falls down and quickly covers the burning oil pan, cutting off the contact between the fire source and the air, so that the fire is quickly extinguished without affecting the cooking environment.

[0089] 2. A temperature sensor 14 is provided at the bottom of the smoke collecting hood or on the smoke baffle 23, so as to judge whether the oil pan is on fire according to a preset temperature threshold and a preset time threshold.

[0090] 3. After the fire is extinguished, the range hood will run at high speed to quickly expel harmful gases and improve the air quality in the kitchen.

[0091] 4. A quick drop distance L4 of the fire extinguishing pot cover 210 is defined. In this way, the fire extinguishing pot cover 210 can drop quickly within this distance, shortening the fire extinguishing time. At the same time, the fire extinguishing pot cover 210 can impact the pot 22 when it falls quickly, avoiding hot oil splashing and scalding the user.

[0092] 5. Use the working current of the rotating motor to determine whether the fire extinguishing pot cover 210 is installed normally, reduce other control signals such as micro switches, and reduce costs.

[0093] 6. The controller has a preset fire extinguishing safety time to prevent the oil pan from reigniting after the fire extinguishing pot cover 210 is retracted.

[0094] 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 should be based on the protection scope of the claims.
