[0036] Please refer to Figure 1 The embodiment provides a stove fire extinguishing device 10, which comprises a storage box assembly 100 and at least one fire extinguishing assembly.

[0037] The storage box assembly 100 is located above the stove head 21, and the storage box assembly 100 has a containing groove 111 with an opening facing downward; the storage box assembly 100 is configured to be able to make the containing groove 111 directly face the stove head 21 when extinguishing fire;

[0038] The fire extinguishing assembly comprises a fire extinguishing pot cover 210, a rope 300 and a motor mechanism 230; one end of the rope 300 is connected with the fire extinguishing pot cover 210, and the other end is connected with a rotor of the motor mechanism 230; the rope 300 comprises a vertical section 320, one end of the vertical section 320 is connected with the top end of the fire extinguishing pot cover 210, and the other end extends to the center of the containing groove 111; and the length of the vertical section 320 is less than the distance between the storage box and the vertical line direction of the bottom of the pot 22 placed on the stove head 21;

[0039] The motor mechanism 230 is configured to rotate forward to tighten the rope 300 so that the fire extinguishing pot cover 210 is stored in the containing groove 111; or is configured to rotate reversely to release the rope 300 so that the fire extinguishing pot cover 210 falls into the pot 22.

[0040] The fire extinguishing assembly of the scheme releases or winds the rope 300 through the motor mechanism 230, so that the fire extinguishing pot cover 210 connected with the rope 300 can fall into the pot 22 or be stored in the containing groove 111 of the storage box assembly 100. When the motor mechanism 230 reversely releases the rope 300 to make the fire extinguishing pot cover 210 fall into the pot 22, the fire extinguishing pot cover 210 can cover the oil pot on fire at this time, cut off the contact between the combustible and air, and make the fire extinguish rapidly. After the fire extinguishing is completed, the motor mechanism 230 rotates forward to tighten the rope 300 so that the fire extinguishing pot cover 210 is stored in the containing groove 111, so as to avoid interference to the cooking operation, and facilitate repeated use of the fire extinguishing pot cover 210. The length of the rope 300 is equivalent to the distance between the containing groove 111 and the bottom of the pot, so that the rope 300 can pull the fire extinguishing pot cover 210, prevent the fire extinguishing pot cover 210 from impacting the pot 22 when falling rapidly, and avoid splashing of hot oil and scalding of the user. Therefore, the stove fire extinguishing device 10 has the advantages of convenient operation, good fire extinguishing effect and no influence on the cooking environment.

[0041] Please continue to refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 to understand more structural details of the stove fire extinguishing device 10.

[0042] In the embodiment of the utility model, the rope 300 is detachably connected with the fire extinguishing pot cover 210. After extinguishing the fire, the user can conveniently clean and install the fire extinguishing pot cover 210. Optionally, the accommodating groove 111 is a circular column groove, and the fire extinguishing pot cover 210 is a circular cover body.

[0043] In the optional embodiment, the storage box assembly 100 comprises a body 110, a front glass 120 and an alarm unit 130; the accommodating groove 111 is located at the bottom of the body 110; the front glass 120 is bonded to the front side of the body 110, and the plate surface of the front glass 120 is provided with a sealing strip; when the storage box assembly 100 is retracted into the inner cavity of the smoke baffle 23, the sealing strip is tightly matched with the smoke baffle 23; the alarm unit 130 is arranged inside the body 110.

[0044] Further, the alarm unit 130 can be a display, voice and other alarm schemes. For example, the alarm unit 130 can comprise a display screen, which is opposite to the front glass 120; the display screen can display fire extinguishing alarm words and patterns, and can also display the fire extinguishing state of the stove fire extinguishing device 10, the position state of the fire extinguishing pot cover 210 and the temperature condition of the current smoke machine, etc. At the same time, the alarm unit 130 can comprise a loudspeaker, which can broadcast fire situation alarm, fire extinguishing indication, broadcast the position condition of the fire extinguishing pot cover 210, etc.

[0045] Please continue to refer to Figure 1 , Figure 2 and Figure 3 As can be seen from the drawings, in the optional embodiment, the stove fire extinguishing device 10 further comprises a guide rail 510 and a driving mechanism 520; the smoke baffle 23 has an inner cavity capable of accommodating the storage box assembly 100; the guide rail 510 is arranged on the smoke baffle 23, and the storage box assembly 100 is slidably matched with the guide rail 510; the fixed end of the driving mechanism 520 is connected with the smoke baffle 23, and the driving end of the driving mechanism 520 is connected with the storage box assembly 100, so as to drive the storage box assembly 100 to retract into the inner cavity or move away from the smoke baffle 23.

[0046] Because the width of the smoke baffle 23 is less than the width of the lower machine provided with the stove head 21, so as to ensure that the upper part of the pot 22 of the stove head 21 has a larger operation space. The storage box can be extended to the upper part of the stove head 21 to ensure that the fire extinguishing device vertically falls to the pot 22 to achieve fire extinguishing; at the same time, the storage box can be retracted into the smoke baffle 23 to ensure that the upper part of the stove head 21 has a larger operation space; and the fire extinguishing pot cover 210 can be timely stored to ensure the overall cleanliness.

[0047] Optionally, the driving mechanism 520 is an electric push rod.

[0048] It can also be seen from the figure that in an alternative embodiment, the motor mechanism 230 is arranged on the smoke baffle 23, the storage box assembly 100 is connected with the smoke baffle 23, one end of the rope 300 is connected with the motor mechanism 230, the other end passes through the center hole 112 of the accommodating groove 111 opposite the top of the cooking head 21 and is connected with the fire extinguishing pot cover 210, and the rope 300 further comprises a horizontal section 310 from the motor mechanism 230 to the center of the accommodating groove 111. In this way, the motor mechanism 230 is arranged on the smoke baffle 23, which can reduce the impact of the storage box itself on the fire extinguishing pot cover 210, and ensure the stability and reliability of the storage box.

[0049] Further, in an alternative embodiment, the storage box assembly 100 further comprises a bracket assembly 400, the bracket assembly 400 comprises a rotating shaft 410 and a shaft bracket 420, the rotating shaft 410 is rotatably arranged on the shaft bracket 420, the center of the accommodating groove 111 has a through center hole 112, the shaft bracket 420 is arranged on the center hole 112, and the rotating shaft 410 is flush with the center hole 112, and the rope 300 passes around the surface of the rotating shaft 410 to pass through the center hole 112 and is connected with the fire extinguishing pot cover 210.

[0050] The shaft bracket 420 is arranged on the center hole 112 of the accommodating groove 111, and the rotating shaft 410 is flush with the center hole 112 of the accommodating groove 111. That is, the horizontal section 310 of the rope 300 can pass around the rotating shaft 410 to turn and connect with the vertical section 320, thus ensuring the smoothness of the entire rope 300 when the fire extinguishing pot cover 210 falls. On the other hand, the shaft bracket 420 can also ensure the effective sliding of the rope 300 and make the fire extinguishing pot cover 210 keep vertical with the center of the pot 22.

[0051] In an alternative embodiment, at least one boss 240 is arranged on the bottom of the accommodating groove 111, the boss 240 extends towards the opening direction of the accommodating groove 111, a plurality of bosses 240 are uniformly arranged around the center of the accommodating groove 111, and when the fire extinguishing pot cover 210 is stored in the accommodating groove 111, the plurality of bosses 240 abut against the top surface of the fire extinguishing pot cover 210.

[0052] The plurality of bosses 240 serve as support points when the fire extinguishing pot cover 210 is stored in the accommodating groove 111, which can reduce the contact area between the storage box body 110 and the fire extinguishing pot cover 210 and ensure that the fire extinguishing pot cover 210 falls quickly at the first time.

[0053] Please continue to refer to Figure 4As can be seen from the figure, in the optional embodiment, the distance between the center of the accommodating groove 111 and the vertical direction of the top of the cooking head 21 is L2; the distance between the top of the cooking head 21 and the lowest point after the falling of the fire extinguishing pot cover 210 is L3; and the length of the vertical section 320 of the rope 300 is L2-L3. Such a setting can prevent the fire extinguishing pot cover 210 from impacting the pot 22 during the falling process, avoid the splashing of hot oil, and scald the user.

[0054] Further, the length of the horizontal section 310 is L1; and the total length of the rope 300 is L=L1+L2-L3.

[0055] In the optional embodiment, the motor mechanism 230 is an electric motor. It can be understood that in other embodiments of the utility model, the motor mechanism 230 can also be a hydraulic motor, a pneumatic motor, etc., which is only an example here.

[0056] It should be noted that in order to quickly extinguish the fire, a quick falling distance L4 is set. The length value of L4 is less than the length value of L2.

[0057] In the stroke of L4, the electric motor operates at n times (n is a natural number greater than or equal to 1) of the normal speed to shorten the falling time of the fire extinguishing pot cover 210.

[0058] Optionally, the quick falling distance L4 can be converted into the speed drop time threshold of the quick work of the electric motor according to the rated speed of the electric motor, the length of L4 and the setting value of n times.

[0059] That is, the electric motor starts to work, rotates quickly within the speed drop time threshold, and works at the normal speed after reaching the time threshold; when the working current is less than the rated current, it can be judged that the fire extinguishing pot cover 210 contacts the pot 22, and at this time the electric motor stops working.

[0060] In the optional embodiment, a temperature sensor 14 is further included, which is arranged on the bottom of the smoke hood or the smoke baffle 23, and can be electrically connected with the motor mechanism 230.

[0061] When the oil pot catches fire and the flame is sucked into the air duct, the temperature sensor 14 is greater than the preset temperature threshold and the preset time threshold, the electric push rod pushes the storage box assembly 100 to the designated position, and then the electric motor releases the fire extinguishing pot cover 210, which can cover the oil pot on fire, cut off the contact between the combustible and the air, and make the fire extinguish quickly. When the working current of the electric motor is less than the rated current, it can be judged that the fire extinguishing pot cover 210 contacts the pot 22, and at this time the electric motor stops working.

[0062] After the temperature of the temperature sensor 14 is less than the preset temperature threshold, the range hood starts to work at high speed to quickly discharge harmful gas and improve the air quality in the kitchen.

[0063] After receiving the fire extinguishing pot cover 210 reset signal, the motor works to recover the fire extinguishing pot cover 210; when the motor current reaches the preset locked-rotor current, it is judged that the fire extinguishing pot cover reaches the specified position, at which time the electric push rod recovers the storage box assembly 100 to the specified position.

[0064] It should be noted that the fire extinguishing pot cover 210 reset signal can be a signal sent by triggering the keys (such as the fire extinguishing pot cover 210 reset key) of the operation panel, or a type of micro switch provided in the accommodating groove 111 that is triggered.

[0065] Further, in order to ensure effective fire extinguishing, the stove fire extinguishing device 10 sets a fire extinguishing safety time, that is, the time during which the temperature sensor 14 needs to maintain below the set preset temperature threshold after fire extinguishing, to prevent the oil pot from reigniting after the fire extinguishing pot cover 210 is recovered. In this way, without the fire extinguishing pot cover 210 reset key, the fire extinguishing pot cover 210 can be automatically reset according to the combination of the temperature threshold of the temperature sensor 14 and the fire extinguishing safety time.

[0066] In addition, according to the detection principle of the motor, the system can monitor the working current of the electric push rod to identify whether the storage box assembly 100 is normally pushed out or reset, and a micro switch can also be provided on the storage box body 110 to judge its working state.

[0067] In the second aspect, the utility model provides a kind of integrated stove 20, including the stove fire extinguishing device 10 of any one of the foregoing embodiments. The smoke baffle 23 is fixed on the smoke collecting hood assembly 24, and the movable storage box assembly 100 is arranged in the smoke baffle 23. The electric push rod body 110 is fixed on the smoke baffle 23, the storage box assembly 100 is connected with the smoke baffle 23 through left and right guide rails 510, and is connected with the electric push rod movably, to realize the stable contraction of the storage box assembly 100.

[0069] 1, the bottom of the storage box is provided with a fire extinguishing pot cover 210. In this way, when the oil pot catches fire, the fire extinguishing pot cover 210 falls and quickly covers the oil pot on fire, cutting off the contact between the fire source and the air, so that the fire is quickly extinguished without affecting the cooking environment.

[0070] 2, the recess of the storage box body 110 is provided with three or a plurality of small bosses 240. In this way, the contact area of the storage box body 110 and the fire extinguishing pot cover 210 is reduced to ensure that the safety pot cover falls effectively in the first time.

[0071] 3, the temperature sensor 14 is arranged on the bottom of the smoke collecting hood or the smoke baffle 23. In this way, whether the oil pot is on fire is judged according to the temperature threshold and the time threshold.

[0072] 4、In the fire, the smoke machine runs at high speed, so as to quickly discharge harmful gas, improve the air quality of the kitchen.

[0073] 5、The top of the fire extinguishing pot cover 210 is provided with a detachable rope 300, so that after the fire is extinguished, the user can conveniently clean the pot cover and install it.

[0074] 6、The length L of the rope 300 is defined, so as to prevent the impact of the pot 22 when the fire extinguishing pot cover 210 quickly falls, and to avoid the splashing of hot oil and scalding the user.

[0075] 7、The bracket assembly 400 is arranged on the storage box, which can ensure the effective sliding of the rope 300 and is perpendicular to the center of the pot.

[0076] 8、The fire extinguishing pot cover 210 quickly falls within the distance L4, so as to shorten the fire extinguishing time, prevent the impact of the pot 22 when the fire extinguishing pot cover 210 quickly falls, and avoid the splashing of hot oil and scalding the user.

[0077] 9、The motor working current is used to judge whether the fire extinguishing pot cover 210 is normally installed, so as to reduce other control signals such as microswitch and reduce the cost.

[0078] 10、The system sets the fire extinguishing safety time to prevent the oil pot from rekindling after the fire extinguishing pot cover 210 is recovered.
