Description

Technical Field

[0001] This application relates to the field of smoke machine equipment technology, and in particular to a smoke machine fire detection and extinguishing structure, system and smoke machine. Background Technology

[0002] With the rapid development of IoT technology and smart homes, the intelligence level of cooktops and range hoods is increasing. Therefore, kitchen safety, especially fire prevention for gas cooktops, is of paramount importance in home fire prevention. Range hoods operate in high-temperature, high-fume environments, and are usually located directly above open-flame cooktops, thus posing a fire hazard. If the cook forgets to turn off the stove when leaving temporarily, causing pots and pans to dry-burn or overflow and ignite nearby combustibles, a fire can easily occur without timely warning and intervention. Therefore, some range hoods with fire detection functions have emerged in existing technologies.

[0003] However, these range hoods typically detect abnormal flames or high temperatures using thermocouples or infrared sensors. This approach has significant limitations. First, it is susceptible to interference from light or other heat sources, leading to false alarms and impacting user experience. Second, the sensor's installation location directly affects its detection effectiveness. Improper installation can not only cause performance degradation due to oil fume pollution but may also result in blind spots that fail to effectively cover the stove area, ultimately leading to poor fire hazard detection. Utility Model Content

[0004] To address the issue of poor detection performance in existing range hoods with fire detection capabilities, this application provides a fire detection and extinguishing structure, system, and range hood. By integrating a fire detection component and an extinguishing component on the smoke baffle, and combining photosensitive and temperature detection components, the photosensitive component senses specific wavelengths of light emitted by an open flame, while the temperature detection component monitors abnormally high temperatures. The combination of these two pieces of information can effectively distinguish between real fires and interference from everyday cooking, greatly reducing the false alarm rate. Furthermore, the fire detection and extinguishing system is used in conjunction with the range hood's self-cleaning system, reusing the water source and eliminating the need for a complete water system and storage device, thus greatly simplifying the structure and saving valuable internal space of the range hood.

[0005] In a first aspect, embodiments of this application provide a fire detection and extinguishing structure for a smoke hood, including a fire detection component and a fire extinguishing component; The flame detection assembly includes a photosensitive detector and a temperature detector, which are mounted on the smoke baffle of the smoke hood. The fire extinguishing assembly includes a water outlet and a water pipe; the water outlet is located on the range hood and faces the stove; one end of the water pipe is connected to the water outlet, and the other end is connected to the cleaning pipe of the range hood.

[0006] In one possible embodiment, the device also includes a housing, with the flame detection assembly disposed inside the housing, and a light-transmitting area provided on the housing.

[0007] In one possible embodiment, the smoke baffle is made of glass and the housing is made of sheet metal. The housing is semi-enclosed; the temperature sensing element is located on one side of the housing.

[0009] In one possible embodiment, the temperature sensing element is vertically positioned inside the housing.

[0015] The fire detection and extinguishing structure, system, and fire extinguisher provided in this application have the following technical effects: The range hood's fire detection and extinguishing structure includes a fire detection component and an extinguishing component. The fire detection component includes a photosensitive detector and a temperature detector, which are mounted on the range hood's baffle plate. The extinguishing component includes a water outlet and a water pipe. The water outlet is located on the range hood and faces the cooktop. One end of the water pipe is connected to the water outlet, and the other end is connected to the range hood's cleaning pipeline. In this embodiment, by integrating the fire detection component and the extinguishing component on the baffle plate, and combining the photosensitive detector and the temperature detector, the photosensitive detector senses specific wavelengths of light generated by an open flame, while the temperature detector monitors abnormally high temperatures. The combination of these two pieces of information can effectively distinguish between real fires and interference from daily cooking, greatly reducing the false alarm rate.

[0022] To make the objectives, technical solutions, and advantages disclosed in the embodiments of this application clearer, the embodiments of this application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the embodiments of this application and are not intended to limit the embodiments of this application.

[0023] This application provides a fire detection and extinguishing structure for a smoke machine. Figure 1 This is a schematic diagram of a fire detection and extinguishing structure for a smoke hood provided in an embodiment of this application. Figure 1 ,like Figure 1 As shown, the fire detection and extinguishing structure of the smoke hood includes a fire detection component 1 and a fire extinguishing component 2.

[0024] In this embodiment, the flame detection component 1 includes a photosensitive detector 11 and a temperature detector 12, which are disposed on the smoke baffle of the smoke machine.

[0025] In this embodiment of the application, the fire extinguishing component 2 includes a water outlet 21 and a water guide pipe 22; the water outlet 21 is installed on the range hood and faces the stove; one end of the water guide pipe 22 is connected to the water outlet 21, and the other end is connected to the cleaning pipe of the range hood.

[0026] In this embodiment, by integrating a fire detection component 1 and a fire extinguishing component 2 on the smoke baffle, and combining a photosensitive detector 11 and a temperature detector 12, the photosensitive detector 11 senses the specific wavelength of light generated by the open flame, and the temperature detector 12 monitors abnormal high temperatures. The combination of the two information can effectively distinguish between real fires and interference from daily cooking, greatly reducing the false alarm rate. At the same time, the fire detection and extinguishing system is used in conjunction with the range hood's self-cleaning system, and the water source is reused. There is no need to set up a complete water system and water storage device, which greatly simplifies the structure and saves valuable space inside the range hood.

[0027] Figure 2 This is a schematic diagram of a fire detection and extinguishing structure for a smoke hood provided in an embodiment of this application. Figure 2 In one possible embodiment, the fire detection and extinguishing structure of the smoke hood also includes a housing 3, the fire detection component 1 is disposed inside the housing 3, and the housing 3 is provided with a light-transmitting area 31.

[0028] The housing 3 provides an independent installation and protection space for the precision photosensitive detector 11 and temperature detector 12. The housing 3 isolates the flame detection assembly 1 from the oil fumes, moisture, and complex circuits inside the smoke machine, avoiding oil stains and electrical interference, and significantly improving the reliability and service life of the detection elements. Meanwhile, the light-transmitting area 31 ensures that the photosensitive detector 11 can receive external light without obstruction, achieving a balance between protection and functionality.

[0029] In one possible embodiment, the smoke baffle is specifically made of glass, and the housing 3 is specifically made of sheet metal. The housing 3 is semi-enclosed. The temperature detection element 12 is located on one side of the housing 3. By placing the temperature detection element 12 on one side of the housing 3, i.e., the sheet metal side, the heat conducted and radiated from the direction of the stove can be detected more accurately, avoiding the heat insulation or heat conduction delay that the housing 3 itself may cause, and improving the sensitivity and accuracy of temperature detection.

[0030] In one possible embodiment, the range hood fire detection and extinguishing structure further includes a mounting component 4, which comprises bolts and nuts. The housing 3 has a folded edge, and mounting holes are provided on both the folded edge and the smoke baffle. The housing 3 is mounted on the smoke baffle by bolts and nuts passing through the mounting holes. This bolt-nut connection provides a simple and stable structure that can withstand vibrations in the kitchen environment, ensuring the long-term stability of the fire detection component 1.

[0031] In one possible embodiment, the temperature sensing element 12 is vertically arranged inside the housing 3. The vertical arrangement helps to make full use of the height space inside the housing 3, making the structure more compact. Furthermore, the vertical arrangement conforms to the physical law that hot air rises. When the stove flame or high-temperature smoke rises, the vertically arranged sensor can detect the heat source more efficiently and speed up the response.

[0032] Figure 3 This is a schematic diagram of a fire detection and extinguishing structure for a smoke hood provided in an embodiment of this application. Figure 3 In one possible embodiment, the fire extinguishing component 2 further includes a water tank 23, which is located inside the smoke hood and provides water for the smoke hood's self-cleaning and fire extinguishing functions, thus achieving water source sharing and system integration. By setting up a shared water tank 23 to provide water for both self-cleaning and fire extinguishing functions, a high degree of functional integration is achieved. This avoids designing a separate water tank 23 and water circuit for the fire extinguishing system, greatly simplifying the structure, saving valuable space inside the smoke hood, and significantly reducing overall cost and weight.

[0033] In one possible embodiment, the housing is located inside the switch assembly 5 of the range hood, making full use of the space of existing components of the range hood without needing to create an additional installation position for the flame detection assembly 1, thus maintaining the cleanliness and overall aesthetics of the range hood. At the same time, the switch assembly 5 is typically located in the user's operating area, a position that also offers good visibility of the cooktop and does not affect the detection effect.

[0034] In this embodiment, the smoke hood is a near-suction type, and the smoke baffle includes a fixed part and a movable part. The switch assembly 5 is disposed in the fixed part of the smoke baffle. By placing the switch assembly 5, which includes the flame detection assembly 1, in the fixed part, rather than the movable part that can be opened and closed, the position and angle of the flame detection assembly 1 are permanently fixed and will not change due to the opening and closing of the movable part of the smoke baffle, thereby ensuring a constant and reliable fire detection field of view.

[0035] This application also provides a smoke detector and fire extinguishing system, such as... Figure 3 As shown, it includes the above-mentioned fire detection and extinguishing structure for the smoke machine and the cleaning pipeline 6.

[0036] This application also provides a range hood, including the above-mentioned range hood fire detection and extinguishing system and the range hood body.

[0037] By integrating a fire detection component 1 and a fire extinguishing component 2 into the smoke baffle, and combining a photosensitive detector 11 and a temperature detector 12, the photosensitive detector 11 senses the specific wavelength of light generated by the open flame, while the temperature detector monitors abnormal high temperatures. The combination of these two pieces of information can effectively distinguish between real fires and interference from daily cooking, greatly reducing the false alarm rate. At the same time, the fire detection and extinguishing system is used in conjunction with the range hood's self-cleaning system, reusing the water source. There is no need to set up a complete water system and water storage device, which greatly simplifies the structure and saves valuable space inside the range hood.
