Description

Technical Field

[0001] The invention relates to the technical field of kitchen fire protection, and in particular to an Internet of Things automatic power-off fire protection device for an electromagnetic stove in the kitchen. Background Art

[0002] In the current catering industry, in order to comply with the trend of energy conservation and emission reduction or to create civilized cities and protect people's lives and property, many places also prohibit the use of open flames or gas stoves. With this trend, more and more induction cookers are used in catering and household environments, which also makes the development of induction cookers more and more mature. Since the principle of induction cookers is electromagnetic heating, the fire protection process of induction cookers is mainly to prevent the circuit of the induction cooker from overloading and overheating or the ignition of cooking oil in dishes.

[0003] The fire-fighting devices currently used in kitchens are basically passive fire-fighting. They widely sense the fire source and smoke that have occurred in the kitchen area, and are more often used to deal with open flame stoves. They issue sound and light alarms in the room area and mechanically activate dry powder spray to extinguish fires in a wide area.

[0004] The above-mentioned fire extinguishing devices have the following defects: ① Lack of prevention and advance disposal, and can only be used in the stage of extinguishing the fire source after the fire is ignited; ② Harsh conditions and low response time, the fire source sensing trigger adopts medium fusing, which requires the fire source to be unaffected by wind and fire point before it will work; ③ Localized alarm, lack of multi-level linkage disposal, on-site sound and light alarm, lack of custom function of sending alarms to multiple levels, multiple people, and multiple devices; ④ It is difficult to link with other smart kitchen equipment, the information island phenomenon is difficult to improve, and it is difficult to achieve integration with current information technology such as the Internet of Things, apps, and databases.

[0005] In the current catering management process, since the catering industry is mainly composed of retail, small and medium-sized enterprises, and is subject to different corporate profits and fire management requirements, the catering industry does not pay enough attention to the fire protection issues of stoves. At the same time, the intelligent fire protection synthesis system of stoves has a high cross-border degree. It must be based on the hygiene and processing methods in the catering industry, as well as the extension of current smart kitchens, catering operation pain points and other factors to achieve a full-chain solution, which undoubtedly increases the difficulty of research on intelligent fire protection devices.

[0006] In response to the above-mentioned problems existing in the stove management process, for example, the AIoT-based intelligent early warning and prevention method and system for kitchen stove fires disclosed in the patent CN118800018A performs intelligent monitoring of stove fire conditions based on AI algorithms. However, in the implementation process, it needs to be used in conjunction with a fire extinguishing device, and it cannot effectively deal with stove fires by itself, and it is more of a fire extinguishing device, rather than a preventive effect. In view of this, in-depth research was conducted on the above-mentioned problems, resulting in this case. Summary of the invention

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] See also Figure 1-10 The present invention provides an implementation scheme: In the modern kitchen fire fighting process, the current fire fighting mainly adopts the medium fusing method. Therefore, in the kitchen fire fighting process, the reaction time is low and is affected by factors such as wind, which easily causes the instability of kitchen fire fighting. In addition, the fire fighting management system and the degree of attention are different, and it is impossible to link with external intelligent devices, which reduces the intelligence of kitchen fire fighting work and lacks the ability to customize multi-level alarms.

[0043] In response to the above problems, according to the instructions attached Figure 1-4It can be seen that in order to solve the above problems, the present application discloses an Internet of Things automatic power-off fire-fighting device for a kitchen electromagnetic stove, specifically an integrated housing 1 is used as the main body of the device, and the specific integrated housing 1 is a cavity housing with a rectangular structure, and the above-mentioned integrated housing 1 is provided with a mounting component 2 fixed on the building, and the integrated housing 1 can be fixed by the mounting component 2, and the integrated housing 1 is convenient for disassembly and assembly, and a control connector is provided in the integrated housing 1, and the control connector is connected to the power supply line of the electromagnetic stove, and the control connector plays a role in wiring control of the power supply line of the electromagnetic stove, and a specific side of the integrated housing 1 is provided with an incoming wiring terminal 4, and a corresponding side of the integrated housing 1 is provided with an outgoing wiring terminal 5, and a power adapter 8 is provided on one side of the incoming wiring terminal 4;

[0044] In order to improve the structural strength of the integrated casing 1, the integrated casing 1 is a rectangular rolled steel plate shell. One side of the control panel of the integrated casing 1 is fixed to the main body of the integrated casing 1 by screws. A pair of mounting grooves are opened on both sides of the integrated casing 1. The outgoing line terminal 5 and the incoming line terminal 4 are separately fixed to the pair of mounting grooves by screws, and are separately connected to the integrated casing 1 through the incoming line terminal 4 and the outgoing line terminal 5 to complete the wiring with the external circuit, wherein the incoming line terminal 4 is connected to the power supply line of the kitchen through the power adapter 8, and the incoming line terminal 4 is used to divert the power to power each component in the integrated casing 1.

[0045] In view of the detection problem at the current stage, a sensor module 3 is integrated on the integrated housing 1 and connected to the control connector. The information of the external kitchen is detected by the sensor module 3. The specific sensor module 3 at least integrates a human proximity sensor 31, a video processor 32, a millimeter radar sensor 33, a temperature sensor 34 and a smoke sensor 35. The human proximity sensor 31 can detect whether someone is approaching the stove. The video sensor is connected to the video system of the kitchen. The video processor 32 is used to identify and transmit the video information. The millimeter radar sensor 33 can accurately monitor the distance between the human body and the stove. The temperature sensor 34 and the smoke sensor 35 are used as further detection means to detect the temperature and smoke of the stove. When the temperature is too high or the smoke is too large, necessary checks and balances are taken. A central controller 36 is connected to one side of the sensor module 3. A communicator is set on the central controller 36. The data collected by the sensor module 3 is transmitted to the communicator through the central controller 36, and then transmitted to the superior control system by the communicator. The superior control system analyzes various data and takes corresponding corresponding measures according to the analyzed data.

[0046] According to the instruction manual Figure 1-4It can be seen that a circuit breaker control component 6 is provided between the above-mentioned incoming wiring terminal 4 and the outgoing wiring terminal 5, and the circuit breaker control component 6 is connected to the central controller 36. The incoming wiring terminal 4 and the outgoing wiring terminal 5 can be connected through the circuit breaker control component 6 to realize the switching of the incoming wiring terminal 4 and the outgoing wiring terminal 5, and then the outgoing wiring terminal 5 is powered off, thereby realizing the power off of the induction cooker;

[0047] According to the instruction manual Figure 1-6 It can be known that an electronic display screen 37 is arranged on the outer wall of the above-mentioned integrated housing 1 and the side of the integrated housing 1 is a control panel, the electronic display screen 37 is connected to the sensor module 3, and an audible and visual alarm 38 is also arranged on the outer wall of the integrated housing 1 and connected to the central controller 36. A reset button 67 is also arranged on the control panel of the integrated housing 1, and the reset button 67 is connected to the circuit breaking control component 6 for reconnecting the circuit after the circuit breaking. In the specific implementation process, part of the sensors in the sensor module 3 are integrated through the control panel, and the audible and visual alarm 38 and the electronic display screen 37 are integrated, and the central controller 36 is connected through the electronic display screen 37. When the kitchen is in a fire, the detected data is displayed through the electronic display screen 37, and when an alarm is needed, the audible and visual alarm 38 is started, and the audible and visual alarm 38 is used to alarm at a close distance;

[0048] At the same time, in order to prevent the equipment from catching fire internally due to high temperature during use, the present application further provides a gas fireproof partition structure 7 in the integrated housing 1, and effectively isolates the integrated housing 1 through the gas fireproof partition structure 7, and then a line fire extinguishing component 75 is protrudingly provided on one side of the gas fireproof partition structure 7, and the line fire extinguishing component 75 corresponds to one side of the output terminal 5, and one side of the output terminal 5 corresponds to the power supply line of the induction cooker. When the gas fireproof partition structure 7 is working, the fire extinguishing gas is sprayed out through the line fire extinguishing component 75 through the gas fire extinguishing partition structure and blown toward the external power supply line of the induction cooker, thereby extinguishing the line flame.

[0049] According to the instruction manual Figure 5-7 It can be seen that the above-mentioned circuit breaker control component 6 includes a wiring housing 61, which is installed in the integrated housing 1. A wiring tube 62 is arranged in the wiring housing 61, and a wiring spring 63 is arranged axially inside the wiring tube 62. A wiring plug rod 64 is connected to the outlet wiring terminal 5, and the head end of the wiring plug rod 64 is inserted in the wiring tube 62. A limit component 66 is arranged on one side of the middle section of the wiring plug rod 64. The limit component 66 is connected to the central control, and the posture of the limit component 66 can be controlled by the central controller 36. An insulating guide block 65 is arranged at the tail end of the wiring plug rod 64;

[0050] In the specific implementation process, the wiring tube 62 is fixed in position by the wiring housing 61, the wiring spring piece 63 arranged in the wiring tube 62 matches the wiring plug rod 64, and the wiring plug rod 64 adopts a telescopic structure. Specifically, the wiring plug rod 64 is telescopically limited by the cylindrical outer sleeve. When the induction cooker is used normally, the wiring plug rod 64 is inserted into the wiring tube 62, and the wiring plug rod 64 is in contact with the wiring spring piece 63, so that the incoming wiring terminal 4 is connected with the outgoing wiring terminal 5, so as to power the induction cooker, and the induction cooker is powered by the wiring plug rod 64. The limit assembly 66 limits the terminal plug 64. When a fire alarm occurs, the limit assembly 66 is controlled by the central controller 36 to release the limit on the terminal plug 64, so that the terminal plug 64 is pushed back by the spring to break away from the contact between the terminal plug 64 and the terminal spring 63, thereby separating the power of the output terminal 5. During use, in order to avoid large arcs when power is connected and disconnected, an arc grid can be set at the contact position between the terminal tube 62 and the terminal plug 64 to separate large arcs.

[0051] According to the instruction manual Figure 6 It can be seen that the above-mentioned limiting assembly 66 includes a guide tube 661, which is arranged on one radial side of the wiring plug rod 64, a limiting rod 662 is inserted in the guide tube 661, a limiting slot 663 is provided on one side of the wiring plug rod 64, the limiting rod 662 is reversely pushed and engaged with the limiting slot 663 by a limiting spring 664, and an electromagnet 665 is provided at the inner end of the guide tube 661 to interact with the reverse pull magnet at the end of the limiting rod 662;

[0052] During the specific implementation process, the limit rod 662 is guided and limited by the guide tube 661, so that the limit rod 662 can move along the axial direction of the guide tube 661. When the wiring plug 64 is connected to the wiring tube 62, the limit rod 662 is inserted into the limit slot 663 under the action of the limit spring 664, and the wiring plug 64 is clamped by the limit rod 662. When the limit is released, the limit rod 662 is retreated along the guide tube 661 through the action of the electromagnet 665 and the reverse pull magnet at the end of the limit rod 662, so that the limit rod 662 releases the limiting effect on the wiring plug 64, so that the wiring plug 64 is pulled out of the wiring tube 62 under the reverse push action.

[0053] According to the instruction manual Figure 7 It can be seen that the reset button 67 includes a guide seat 671, which is mounted on the control panel of the integrated housing 1, and a telescopic rod 672 is mounted on the guide seat 671. The end of the telescopic rod 672 is connected to a reset dial button 674 through a connecting rod 673, and the reset dial button 674 contacts and cooperates with the insulating guide block 65.

[0054] In the specific implementation process, when the alarm is lifted and the kitchen fire is under control, the guide seat 671 cooperates with the telescopic rod 672. A reset spring 675 is installed on the guide seat 671. The reset spring 675 is connected to the end of the telescopic rod 672. An insulating button 676 is provided at the end of the telescopic rod 672. By pressing the insulating button 676, the insulating button 676 presses down the telescopic rod 672, so that the telescopic rod 672 drives the connecting rod 673 to move. The connecting rod 673 is linked with the reset dial button 674, so that the reset dial button 674 is inserted into the insulating guide block 65 at the end of the wiring plug 64, and the reset dial button 674 is continued to be pressed down. Under the radial limiting action of the insulating guide block 65, the reset dial button 674 makes the insulating guide block 65 move axially, pushing the wiring plug 64 back into the wiring tube 62, and in the process, the limiting rod 662 is pushed into the limiting slot 663 to achieve the limiting action on the wiring plug 64.

[0055] According to the instruction manual Figure 4 It can be known that the above-mentioned installation component 2 includes at least two pairs of connecting angle plates 21, and at least two pairs of connecting angle plates 21 are arranged on the back of the integrated casing 1. The connecting angle plates 21 are provided with mounting holes, and magnetic seats 22 are embedded in the mounting holes. During installation, the magnetic seats 22 on the back of the integrated casing 1 are adsorbed with the metal plates embedded in the building, so as to fix the position of the integrated casing 1, and facilitate the disassembly and assembly of the integrated casing 1.

[0056] According to the instruction manual Figure 8-10 It can be seen that the gas fireproof partition structure 7 includes a built-in gas cylinder 71, the bottle mouth of the built-in gas cylinder 71 is connected to a diverter valve head 72, the integrated housing 1 is a double-layer structure, the diverter valve head 72 is provided with an internal communication groove connected to the middle cavity of the integrated housing 1, and a funnel 73 is provided in the built-in gas cylinder 71. Two reactants are respectively contained on both sides of the funnel 73, and a telescopic plugging component 74 is provided at the end of the funnel 73, and the telescopic plugging component 74 is connected to the central controller 36;

[0057] In the specific implementation process, the double-layer structure of the side arm of the integrated casing 1 is used as a storage space for fire extinguishing gas. However, in daily use, the fire-fighting gas does not need to be sprayed out, so a built-in gas cylinder 71 is provided. A funnel 73 is provided in the built-in gas cylinder 71 to separate the two reactants. The present application preferably provides a fire-fighting gas, namely carbon dioxide, which is filled into the double-layer annulus of the integrated casing 1 to play a protective role. The two reactants are sodium carbonate powder and dilute hydrochloric acid solution. The funnel 73 is used to hold the sodium carbonate powder. The telescopic sealing component 74 seals the bottom of the funnel 73 under normal conditions. The telescopic sealing component 74 is controlled by the temperature sensor 34 and the smoke sensor 35 under the control of the central controller 36. When a fire breaks out quickly, the central controller 36 controls the telescopic sealing component 74 to release the seal on the bottom of the funnel 73, so that the sodium carbonate powder falls into the dilute hydrochloric acid solution at a uniform speed. Under the pressure of the gas expansion, the carbon dioxide protective gas rises. The fire extinguishing assembly 75 is connected to the line fire extinguishing assembly 75 on the other side of the diverter valve head 72. When the gas is generated, the line fire extinguishing assembly 75 acts to spray the carbon dioxide fire extinguishing gas along the side of the terminal block to the fire source, and uses the carbon dioxide to extinguish the flame of the line and the electromagnetic stove. On the one hand, the efficiency of the preliminary treatment is improved to prevent the fire from spreading, and on the other hand, the line of the electromagnetic stove is protected. Specifically, the line fire extinguishing assembly 75 includes a pair of air supply pipes 751, which are arranged on both sides of the outlet terminal block 5. The pair of air supply pipes 751 are connected to the diverter valve head 72. In the specific implementation process, a pair of mounting holes are opened on the side wall of the integrated housing 1. A pair of air supply heads 752 are arranged at the ends of the pair of air supply pipes 751 and inserted into the pair of mounting holes. The carbon dioxide is diverted from the pair of air supply pipes 751 to the pair of air supply heads 752 through the diverter valve head 72, and the pair of air supply heads 752 are used to spray the carbon dioxide protective gas outward.

[0058] According to the instruction manual Fig. 9 It can be known that the telescopic sealing assembly 74 includes a guide hole 741. A guide hole 741 is provided on the radial side of the built-in gas cylinder 71. A guide rod 742 is installed in the guide hole 741. The outer end of the guide rod 742 is connected to a control push rod 743. A sealing block 744 is provided at the end of the guide rod 742. The sealing block 744 is sealed at the bottom of the funnel 73. An isolation layer 745 is provided on the built-in gas cylinder 71. The isolation layer 745 is respectively connected to the diverter valve head 72 and the bottom of the built-in gas cylinder 71.

[0059] In the specific implementation process, the guide hole 741 cooperates with the guide rod 742 to limit the guide rod 742. When the central controller 36 receives the control signal, the central controller 36 controls the guide rod 742 to pull the blocking block 744 to move, so that the blocking block 744 releases the blocking effect on the bottom hole of the funnel 73, allowing the sodium carbonate powder to fall, and the isolation layer 745 is set to isolate the reaction raw materials and allow gas to pass through, and then the diverter valve head 72 and the built-in gas cylinder 71 are connected in a split manner, and the built-in gas cylinder 71 can be disassembled and assembled to facilitate the replacement of the built-in gas cylinder 71.

[0060] From the above, it can be generally known that the automatic power-off fire-fighting device of the kitchen induction cooker IoT is designed and integrated with multiple sensors according to the characteristics of the induction cooker, so as to realize a fire-fighting strategy with prevention as the main focus, and comprehensively monitor the kitchen environment at the same time.
