Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, and particularly relates to an intelligent fire extinguishing device for a kitchen stove. Background Art

[0002] A kitchen is a room where food can be prepared and cooked. The equipment usually included in a modern kitchen includes a stove, a sink, and food storage equipment.

[0003] For example, the utility model with the publication number CN216022769U discloses an intelligent fire extinguishing device for a kitchen stove, which includes a fire extinguishing box, a connecting water pipe, and a mounting and fixing frame. The bottom of the mounting and fixing frame is fixedly connected with a conveying water pipe, the side surface of the conveying water pipe is provided with a nozzle connecting piece, and the bottom of the nozzle connecting piece is fixedly installed with a nozzle. In this intelligent fire extinguishing device for a kitchen stove, through the mutual cooperation among the internal thread fixing ring, the protective sleeve, the rubber sealing plug, the rubber pulling strip, the L-shaped limiting block, the notch, and the sealing ring, the nozzle can be protected to prevent external oil fume particles from entering the inside of the protective sleeve, and it can also avoid the nozzle being blocked due to contact with oil fume. When a large amount of oil fume adheres to the surface of the protective sleeve, the protective sleeve can be rotated down from the inside of the internal thread fixing ring, so that the protective sleeve can be cleaned and replaced, thereby improving the protective effect of the protective sleeve.

[0004] In the process of implementing the present application, it is found that this technology has the following problems: Most of the existing intelligent fire extinguishing devices for kitchen stoves monitor the temperature through a temperature monitor to trigger the fire extinguishing device, so as to improve the intelligence of the fire extinguishing device during use. However, most temperature monitors are installed on one side of the fire extinguishing box, and the fire extinguishing box is relatively heavy and cannot be placed on the upper end of the stove. When a fire occurs on the stove, the high temperature delay and the movement path of the flame are both upward, so that the subsequent temperature monitor cannot trigger the fire extinguishing box in the first time during use, thus reducing the practicability of the device.

[0005] Therefore, an intelligent fire extinguishing device for a kitchen stove is proposed. Content of the Utility Model

[0006] The purpose of the present utility model is to solve the problem that most temperature monitors are installed on one side of the fire extinguishing box, and the fire extinguishing box is relatively heavy and cannot be placed on the upper end of the stove.

[0011] Further, the limiting mechanism includes a square frame fixing rod, a square frame connecting rod and a back plate. The square frame connecting rod is installed on the outer surface of the fire extinguisher box. A groove is formed in the inner wall of the back of the cabinet. The back plate is clamped inside the groove of the cabinet. Two sets of T-shaped fixing rods are installed on the front surface of the back plate. The square frame fixing rod is installed on the front surfaces of the two sets of T-shaped fixing rods. The upper surface of the square frame fixing rod abuts against the lower surface of the square frame connecting rod. Four sets of threaded holes are formed in the front surface of the back plate. Four positioning bolts are threadedly connected inside the four sets of the back plate.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. By arranging the fire extinguisher box inside the cabinet, the position of the fire extinguisher box is located directly above the cooking range. Then, by installing the temperature monitor on the lower surface of the fire extinguisher box, the temperature monitor can quickly detect a fire occurring on the cooking range during subsequent use. Furthermore, the temperature monitor can quickly trigger and start the solenoid valve to discharge the extinguishing agent accumulated inside the fire extinguisher box, thereby shortening the time consumed by the subsequent fire extinguishing mechanism during the fire extinguishing process, and further reducing the property losses and casualties caused by subsequent kitchen fires. Therefore, the practicability of the device is improved.

[0028] Such as Figures 1 to 6As shown in the figure, an intelligent fire extinguishing device for a kitchen stove includes a cabinet 1 and a stove. The cabinet 1 is installed on the front of the upper wall of the stove. A card slot is opened on the lower surface of the cabinet 1. An extinguishing mechanism 2 for quickly extinguishing the fire at the outer end of the stove is arranged inside the card slot of the cabinet 1. A rectangular groove is opened on the lower surface of the cabinet 1. A protection mechanism 3 is installed inside the rectangular groove of the cabinet 1. A limiting mechanism 4 for restricting the moving range of the extinguishing mechanism 2 inside the cabinet 1 is arranged on the back of the extinguishing mechanism 2. A sealing mechanism 6 is arranged on the outer surface of the extinguishing mechanism 2. A rectangular card slot is opened on the upper surface of the extinguishing mechanism 2. A driving mechanism 5 is clamped inside the rectangular card slot of the extinguishing mechanism 2. Specifically, by installing the extinguishing mechanism 2 at the upper end of the stove, it can quickly detect the fire on the stove during the subsequent use of the extinguishing mechanism 2, so that the extinguishing mechanism 2 can quickly spray out the accumulated fire extinguishing agent inside, thereby shortening the time consumed by the extinguishing mechanism 2 during the subsequent fire extinguishing process, and further reducing the property losses and casualties caused by subsequent kitchen fires, thus improving the practicality of the device.

[0029] As Figure 1 , Figure 2 and Figure 5 shown in the figure, the extinguishing mechanism 2 includes an extinguishing box 201 and an electromagnetic valve 205. The extinguishing box 201 is placed at the bottom of the inner wall of the cabinet 1. A temperature monitor 203 and a connecting pipe 202 are arranged on the lower surface of the extinguishing box 201. The temperature monitor 203 and the connecting pipe 202 are both arranged inside the card slot of the cabinet 1. Multiple drainage holes are opened on the lower surface of the connecting pipe 202. Atomizing nozzles 204 are installed inside the multiple drainage holes of the connecting pipe 202. The positions of the multiple atomizing nozzles 204 and the temperature monitor 203 are both located at the upper end of the stove. Specifically, by arranging the extinguishing box 201 inside the cabinet 1, the position of the extinguishing box 201 is located at the upper end of the stove. Then, by installing the temperature monitor 203 on the lower surface of the extinguishing box 201, the temperature monitor 203 can quickly detect the fire on the stove during the subsequent use, so that the temperature monitor 203 can quickly trigger the electromagnetic valve 205 to discharge the accumulated fire extinguishing agent inside the extinguishing box 201, thereby shortening the time consumed by the extinguishing mechanism 2 during the subsequent fire extinguishing process, and further reducing the property losses and casualties caused by subsequent kitchen fires, thus improving the practicality of the device.

[0030] As Figures 1 to 5As shown, the protection mechanism 3 includes an iron sheet 310, a U-shaped fixing plate 301 and a hinge 302. The iron sheet 310 is installed in the U-shaped groove of the cabinet 1. The lower surface of the iron sheet 310 is adsorbed with a magnetic block 304. The lower surface of the magnetic block 304 is installed with a U-shaped fixing frame 305. The U-shaped fixing plate 301 is installed on the lower surface of the U-shaped fixing frame 305. The upper surface of the U-shaped fixing plate 301 abuts against the lower surface of the cabinet 1. The lower surface of the U-shaped fixing plate 301 is hinged with a bottom plate 303 through a hinge 302. The upper surface of the bottom plate 303 is provided with a groove. The monitoring end of the temperature monitor 203 is inserted into the groove of the bottom plate 303. The upper surface of the bottom plate 303 is installed with a fixing block 308. The fixing block 308 is installed on the upper surface of the fixing block 308. 08 is provided with a groove on the front side, a hydraulic cylinder 306 is provided on the front inner wall of the U-shaped fixed plate 301, a limiting block 307 is installed on the output end of the hydraulic cylinder 306, and the end of the limiting block 307 away from the hydraulic cylinder 306 is inserted into the groove of the fixed block 308, a U-shaped support plate 309 is installed on the left inner wall of the U-shaped fixed plate 301, the bottom of the inner wall of the U-shaped support plate 309 abuts against the lower surface of the connecting pipe 202, and the temperature monitor 203 and the control end of the hydraulic cylinder 306 are electrically connected, a U-shaped groove is provided on the lower surface of the bottom plate 303, a sealing gasket 311 is provided inside the U-shaped groove of the bottom plate 303, and the upper surface of the sealing gasket 311 abuts against the lower surface of the U-shaped fixed plate 301;

[0031] Specifically, the upper surface of the magnetic block 304 is adsorbed on the lower surface of the iron sheet 310, so that the upper surface of the U-shaped fixing plate 301 is attached to the lower surface of the cabinet 1, and then the connection pipe 202, the temperature monitor 203 and the multiple groups of atomizing nozzles 204 are arranged inside the U-shaped fixing plate 301, so that when the U-shaped fixing plate 301 is subsequently connected to the lower surface of the cabinet 1, the rectangular sealing cover with an opening at the top formed by the U-shaped fixing plate 301 and the bottom plate 303 shields and protects the connection pipe 202, the temperature monitor 203 and the multiple groups of atomizing nozzles 204, thereby avoiding as much as possible the subsequent multiple groups of atomizing nozzles 204 from being idle. Kitchen fumes accumulate inside the drainage holes of the multiple groups of atomizing nozzles 204, causing the drainage holes of the subsequent multiple groups of atomizing nozzles 204 to be blocked; by electrically connecting the temperature monitor 203 and the control end of the hydraulic cylinder 306, when the subsequent temperature monitor 203 is triggered by high temperature, the hydraulic cylinder 306 is started to drive the limit block 307 to move out of the groove of the fixed block 308, and then under the action of gravity, the bottom plate 303 is rotated along the axis of the hinge 302, and then the bottom plate 303 is rotated outside the spraying path of the multiple groups of atomizing nozzles 204, thereby avoiding as much as possible that the subsequent bottom plate 303 blocks the normal use of the fire extinguishing mechanism 2.

[0032] Meanwhile, the connection between the square frame-shaped fixing plate 301 and the bottom plate 303 is sealed by the gasket 311, so as to prevent kitchen fumes from entering the interior of the square frame-shaped fixing plate 301 along the connection gap between the bottom plate 303 and the square frame-shaped fixing plate 301 as much as possible; the protection mechanism 3 shields the parts of the fire extinguishing mechanism 2 exposed outside the cabinet 1, thus improving the aesthetics of the device during subsequent idle periods; the bottom of the inner wall of the U-shaped support plate 309 abuts against one end of the connecting pipe 202 away from the fire extinguishing box 201, so that the U-shaped support plate 309 supports one end of the connecting pipe 202 away from the fire extinguishing box 201, thus preventing the end of the connecting pipe 202 away from the fire extinguishing box 201 from swinging back and forth due to water flow impact inside the connecting pipe 202 during subsequent use as much as possible.

[0033] As Figure 1 and Figure 2 shown, the limiting mechanism 4 includes a square frame-shaped fixing rod 401, a square frame-shaped connecting rod 402 and a back plate 404. The square frame-shaped connecting rod 402 is installed on the outer surface of the fire extinguishing box 201. A groove is formed in the inner wall of the back of the cabinet 1. The back plate 404 is clamped inside the groove of the cabinet 1. Two groups of T-shaped fixing rods 403 are installed on the front of the back plate 404. The square frame-shaped fixing rod 401 is installed on the front of the two groups of T-shaped fixing rods 403. The upper surface of the square frame-shaped fixing rod 401 abuts against the lower surface of the square frame-shaped connecting rod 402. Four threaded holes are formed in the front of the back plate 404. Four positioning bolts 405 are threadedly connected inside the four groups of the back plate 404. The external threads of the four positioning bolts 405 pass through the four threaded holes of the back plate 404 and are connected to the interior of the wall; specifically, the back plate 404 is installed on the front of the wall by the four positioning bolts 405 and the two groups of T-shaped fixing rods 403 are installed on the front of the back plate 404. Then, the upper surface of the square frame-shaped fixing rod 401 abuts against the lower surface of the square frame-shaped connecting rod 402, and the square frame-shaped connecting rod 402 is installed on the outer surface of the fire extinguishing box 201, so that the limiting mechanism 4 supports and fixes the fire extinguishing box 201 during subsequent use, thus preventing the lower surface of the cabinet 1 from being crushed when the fire extinguishing box 201 bears too much mass inside, and therefore improving the stability of the fire extinguishing mechanism 2 during subsequent use.

[0034] As Figure 5As shown in the figure, the sealing mechanism 6 includes a fixed ring 601 which is installed on the outer surface of the monitoring end of the temperature monitor 203. A second sealing gasket 602 is bonded to the lower surface of the fixed ring 601, and the lower surface of the second sealing gasket 602 abuts against the upper surface of the bottom plate 303. Specifically, by the lower surface of the second sealing gasket 602 abutting against the upper surface of the bottom plate 303, the second sealing gasket 602 seals the connection between the temperature monitor 203 and the inside of the groove of the bottom plate 303 during use, thus minimizing the subsequent entry of kitchen fumes into the inside of the square frame-shaped fixing plate 301 along the connection gap between the groove of the bottom plate 303 and the temperature monitor 203, which may cause the protection mechanism 3 to be unable to effectively shield and protect the multiple atomizing nozzles 204.

[0035] As Figure 6 shown in the figure, the driving mechanism 5 includes an asbestos protective cover 501 and a power supply 502. A square frame-shaped clamping groove is formed on the upper surface of the fire extinguishing box 201, and the asbestos protective cover 501 is clamped inside the square frame-shaped clamping groove of the fire extinguishing box 201. The power supply 502 is installed at the top of the inner wall of the asbestos protective cover 501, and an electrical connection is made between the output end of the power supply 502 and the access end of the temperature monitor 203. A control panel 206 is installed on the upper surface of the fire extinguishing box 201, and an electrical connection is made between the control panel 206 and the control ends of the hydraulic cylinder 306 and the solenoid valve 205. The position of the control panel 206 is inside the fixed ring 601. Specifically, by the power supply 502 supplying current to the internal electronic devices of the device, the hydraulic cylinder 306 and the solenoid valve 205 can be used normally when the kitchen loses power due to a fire, thus minimizing the inability of the device to extinguish fires normally when a fire occurs in the kitchen. Since the asbestos protective cover 501 has the functions of fire prevention and heat insulation, and the positions of the control panel 206 and the power supply 502 are both arranged inside the asbestos protective cover 501, the asbestos protective cover 501 shields and protects the control panel 206 and the power supply 502 subsequently, thus minimizing the damage to the power supply 502 and the control panel 206 after the high temperature inside the kitchen comes into contact with the power supply 502 and the control panel 206, and therefore improving the service life of the control panel 206 and the power supply 502 during use.

[0036] In summary: By arranging the fire extinguishing box 201 inside the cabinet 1, the fire extinguishing box 201 is located directly above the cooking range. By installing the temperature monitor 203 on the lower surface of the fire extinguishing box 201, the temperature monitor 203 can quickly detect a fire occurring on the cooking range during use, and then the temperature monitor 203 can quickly trigger and start the solenoid valve 205 to discharge the fire extinguishing agent accumulated inside the fire extinguishing box 201, thus shortening the time consumed by the subsequent fire extinguishing mechanism 2 during the fire extinguishing process.

[0037] Meanwhile, by arranging the connecting pipe 202, the temperature monitor 203 and multiple groups of atomizing nozzles 204 inside the rectangular fixing plate 301 in a zigzag shape, when the subsequent rectangular fixing plate 301 is clamped to the lower surface of the cabinet 1, the rectangular sealing cover with an open top formed by the rectangular fixing plate 301 and the bottom plate 303 shields the connecting pipe 202, the temperature monitor 203 and multiple groups of atomizing nozzles 204, thereby minimizing the accumulation of kitchen fumes in the drain holes of the multiple groups of atomizing nozzles 204 during the idle process and preventing blockage of the drain holes of the multiple groups of atomizing nozzles 204. By electrically connecting the temperature monitor 203 and the control end of the hydraulic cylinder 306, when the temperature monitor 203 is triggered by high temperature, the hydraulic cylinder 306 is activated to drive the limiting block 307 out of the groove inside the fixed block 308. Then, under the action of gravity, the bottom plate 303 rotates along the axis of the hinge 302, so that the bottom plate 303 rotates outside the spraying path of the multiple groups of atomizing nozzles 204, thereby minimizing the subsequent blockage of the bottom plate 303 to the normal use of the fire extinguishing mechanism 2.

[0038] In addition, by installing the back plate 404 on the front of the wall with four positioning bolts 405 and installing two T-shaped fixing rods 403 on the front of the back plate 404, and then abutting the upper surface of the zigzag fixing rod 401 against the lower surface of the zigzag connecting rod 402 and installing the zigzag connecting rod 402 on the outer surface of the fire extinguishing box 201, the limiting mechanism 4 supports and fixes the fire extinguishing box 201 during use, thereby minimizing the collapse of the lower surface of the cabinet 1 when the fire extinguishing box 201 bears too much mass, and thus improving the stability of the subsequent fire extinguishing mechanism 2 during use.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
