Description

Technical Field

[0001] This utility model belongs to the field of range hood technology, specifically relating to a range hood that proactively contacts the user in case of environmental anomalies. Background Technology

[0002] Range hoods, as essential kitchen appliances, are primarily used to absorb cooking fumes, odors, and harmful gases released during combustion, such as carbon monoxide and carbon dioxide, to maintain fresh air in the kitchen. However, despite their widespread use and continuous improvements in smoke extraction rates, noise control, and energy efficiency, some significant safety hazards remain. Especially during prolonged use or when unattended, factors such as gas leaks, dry burning, and grease buildup can lead to fires or poisoning accidents.

[0003] Currently, range hoods on the market mainly employ the following technologies to improve purification efficiency and ease of use:

[0004] Variable frequency control technology: Some range hoods are equipped with intelligent variable frequency motors, which can automatically adjust the fan speed according to the smoke concentration to improve the smoke extraction effect while reducing energy consumption.

[0005] High-efficiency filtration systems: Modern range hoods often employ multi-layer filters or centrifugal separation technology to improve oil fume separation efficiency, reduce oil adhesion, and extend service life.

[0006] Touch and remote control functions: Some high-end range hoods already support touch operation and can be connected to a mobile APP through a smart home system to realize functions such as remote on / off and fan speed adjustment.

[0007] However, these improvements still cannot completely solve the security problems that users may encounter during use, and mainly have the following limitations:

[0008] Lacking comprehensive safety monitoring functions, traditional range hoods only focus on the extraction and exhaust of cooking fumes, while lacking effective real-time monitoring of dangerous situations such as gas leaks, abnormal temperatures, and dry burning, thus failing to promptly alert users or allow them to take corresponding safety measures.

[0009] The notification mechanism is lagging or inadequate. Existing range hoods usually use buzzers or indicator lights for local alarms. This method may not be able to receive the alarm in time when the user is away from the kitchen, increasing the risk of accidents.

[0010] Limited intelligence: Although some range hoods support remote control, their automation level is low, still relying on users to manually adjust the fan speed or turn the machine on and off. They fail to achieve intelligent decision-making based on environmental monitoring data, which may prevent them from effectively responding to emergencies in some situations.

[0011] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

[0012] In view of the technical problems mentioned in the background art, the purpose of this utility model is to provide a range hood that monitors by a monitoring probe, collects preset danger parameters through the control chip, and actively contacts the user through a mobile smart APP to prevent gas leakage and dry burning, thereby improving safety, so as to solve the technical problems mentioned in the background art.

[0013] To achieve the above objectives, the present invention provides the following technical solution: a range hood that proactively contacts the user in case of environmental anomalies, comprising a range hood body, a filter assembly at the lower end of the range hood body, and a control assembly at the upper end of the range hood body. The control assembly is mounted on the filter assembly, and the filter assembly includes a filter support. A probe mounting portion is provided at the front end of the filter support, and a monitoring probe is mounted on the surface of the probe mounting portion. The control assembly includes a control bracket, and a mounting panel is mounted on the surface of the control bracket. A control motherboard and a control chip are respectively mounted on the surface of the mounting panel. The control motherboard is electrically connected to the control chip and the monitoring probe. The monitoring probe is used to collect temperature, smoke, and gas concentration data and send them to the control motherboard. The control motherboard transmits the data to the control chip for analysis. In case of an anomaly, the control chip notifies a mobile app to alert the user.

[0014] Furthermore, the monitoring probe has a temperature sensor, a smoke sensor, and a gas concentration sensor, which are electrically connected to the monitoring probe.

[0015] Furthermore, the front end of the filter support is provided with a switch mounting part, the probe mounting part is located at the lower end of the switch mounting part, and a display switch is mounted on the surface of the switch mounting part. The display switch is electrically connected to the control main board.

[0016] Furthermore, the surface of the display switch is provided with a status indicator, a mode switching section and a manual adjustment section, which are arranged in sequence.

[0017] Furthermore, the status indicator includes a green indicator light, a yellow indicator light, and a red indicator light, which are electrically connected to the display switch.

[0018] Furthermore, the manual adjustment unit includes a short-press switch and a long-press switch, which are electrically connected to the display switch respectively.

[0019] Furthermore, the filter support has a filter mounting groove inside, and an oil fume filter is installed in the lower part of the filter mounting groove.

[0020] Furthermore, an air outlet pipe is connected to the upper surface of the control bracket, and the air outlet pipe is fixed to the control bracket by welding.

[0021] The main advantages of this invention are as follows: A monitoring probe is mounted on the surface of the probe mounting part. The monitoring probe has a temperature sensor, a smoke sensor, and a gas concentration sensor. A control motherboard and a control chip are mounted on the surface of the mounting panel. The control motherboard is electrically connected to the control chip and the monitoring probe. The monitoring probe collects temperature, smoke, and gas concentration data at regular intervals and sends them to the control motherboard. The control motherboard transmits the data to the control chip for analysis. The range hood of this invention, which actively contacts the user in case of environmental anomalies, monitors the environment through the monitoring probe and then collects the preset danger parameters through the control chip. It then actively contacts the user through a mobile smart APP to prevent gas leaks and dry burning, thereby improving safety. Attached Figure Description

[0027] like Figures 1 to 4As shown, a range hood that actively contacts users in case of environmental anomalies includes a range hood body 1, a filter assembly 10 at the lower end of the range hood body 1, and a control assembly 20 at the upper end of the range hood body 1, the control assembly 20 being mounted on the filter assembly 10.

[0028] In practical implementation, the filter assembly 10 includes a filter support 11. The upper front end of the filter support 11 has a switch mounting part 111, and the lower end of the switch mounting part 111 has a probe mounting part 112. A monitoring probe 12 is mounted on the surface of the probe mounting part 112. The monitoring probe 12 has a temperature sensor 121, a smoke sensor 122, and a gas concentration sensor 123. These sensors are electrically connected to the monitoring probe 12. In use, the monitoring probe 12 is responsible for detecting key parameters of the kitchen environment and is linked with the intelligent control system of the range hood. The temperature sensor 121 monitors the temperature of the cooking area in real time and alerts the user when the temperature is too high. The smoke sensor 122 detects smoke concentration and identifies abnormal smoke (such as dry burning or burnt food), alerting the user when abnormalities occur. The gas concentration sensor 123 (CO / VOC detection) monitors for natural gas / liquefied petroleum gas leaks and alerts the user when the concentration exceeds the standard.

[0029] In practical implementation, the control component 20 includes a control bracket 21, on the surface of which is mounted a mounting panel 22. A control motherboard 23 and a control chip 24 are mounted on the surface of the mounting panel 22. The control motherboard 23 is electrically connected to the control chip 24 and the monitoring probe 12. During use, the monitoring probe 12 collects temperature, smoke, and gas concentration data at regular intervals (e.g., 1 second) and sends it to the control motherboard 23. The control motherboard 23 then transmits the data to the control chip 24 for analysis. Under normal conditions (environmental data within safe limits), the range hood operates at its default fan speed to ensure air circulation in the kitchen. In abnormal situations (e.g., high smoke concentration, gas leak, overheating), the control chip 24 notifies a mobile app via Wi-Fi / Bluetooth. The user receives an emergency alert: a gas leak has been detected; please check the kitchen immediately. The monitoring probe 12 monitors the gas leak, and the control chip 24 collects pre-set hazard parameters. The app then proactively contacts the user to prevent gas leaks and dry burning, thus improving safety.

[0030] In practical implementation, a display switch 13 is mounted on the surface of the switch mounting part 111. The display switch 13 is electrically connected to the control main board 23. The surface of the display switch 13 is provided with a status indicator part 131, a mode switching part 132, and a manual adjustment part 133, which are arranged sequentially. The status indicator part 131 includes a green indicator light 131a, a yellow indicator light 131b, and a red indicator light 131c. The green indicator light 131a, yellow indicator light 131b, and red indicator light 131c are electrically connected to the display switch 13. The manual adjustment unit 133 includes a short-press switch 133a and a long-press switch 133b, which are also electrically connected to the display switch 13. During use, the green indicator light 131a indicates a normal environment and the range hood is operating in the set mode; the yellow indicator light 131b indicates heavy smoke and increased fan speed, reminding the user to ensure ventilation; and the red indicator light 131c indicates a detected gas leak or abnormal high temperature, automatically switching to the highest fan speed and triggering an alarm. The mode switching unit 132 allows the range hood to automatically adjust its fan speed based on sensor data. The manual adjustment unit 133 includes the short-press switch 133a for switching fan speeds (low, medium, and high, cycling through each other); and the long-press switch 133b for manually turning the range hood on or off.

[0031] In practical implementation, the filter support 11 is provided with a filter installation groove 113 inside, and an oil fume filter 14 is installed in the lower part of the filter installation groove 113. When in use, the oil fume filter 14 can perform preliminary filtration of the inhaled oil fumes, effectively intercept grease particles and impurities, prevent oil stains from entering the exhaust channel, and improve the service life and filtration efficiency of the range hood.

[0032] In practical implementation, the upper surface of the control bracket 21 is connected to the air outlet pipe 25. The air outlet pipe 25 is fixed to the control bracket 21 by welding. When in use, the range hood exhausts the filtered smoke from the kitchen through the air outlet pipe 25 to ensure fresh air and reduce the accumulation of oil fumes.

[0033] In summary, the surface of the probe mounting part 112 is equipped with a monitoring probe 12, which includes a temperature sensor 121, a smoke sensor 122, and a gas concentration sensor 123. The surface of the mounting panel 22 is equipped with a control motherboard 23 and a control chip 24. The control motherboard 23 is electrically connected to the control chip 24 and the monitoring probe 12. The monitoring probe 12 collects temperature, smoke, and gas concentration data at regular intervals and sends them to the control motherboard 23. The control motherboard 23 transmits the data to the control chip 24 for analysis. This utility model's range hood, which proactively contacts users in case of environmental anomalies, monitors the environment through the monitoring probe and then collects pre-set hazard parameters through the control chip. It then proactively contacts the user via a mobile smart APP to prevent gas leaks and dry burning, thereby improving safety.
