Description

Technical Field

[0001] This utility model relates to the field of kitchenware technology, specifically to an intelligent monitoring system for preventing dry burning. Background Technology

[0002] In real-life kitchen life, incidents of pans burning dry occur frequently. When using the kitchen, users may leave for a moment due to some external reasons, which can lead to the pan burning dry. When a pan burns dry, the oil temperature inside the pan becomes too high, producing a lot of oil fumes. These fumes contain harmful substances and pose a safety hazard.

[0003] For example, Chinese patent CN105758529A discloses a safety monitoring device based on non-contact temperature detection, including a control box, an infrared temperature sensor, and a connector; one end of the connector is connected to the control box, and the other end is equipped with the infrared temperature sensor; the infrared temperature sensor is used to detect the outer wall temperature of the container; the control box is equipped with a control circuit and an alarm; if the temperature value detected by the infrared temperature sensor is higher than a preset value, the control circuit will issue an alarm signal.

[0004] However, its technology has the following problems: it measures the temperature inside the pot through an infrared temperature sensor, but the probe needs to be manually pointed at the bottom of the pot, which is cumbersome to use. It also cannot detect when people leave and cannot provide an alarm reminder based on the time people leave.

[0005] Based on this, the present invention designs an intelligent monitoring system for preventing dry burning to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an intelligent monitoring system for preventing dry burning.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An anti-dry-burning intelligent monitoring system includes a range hood and a cooktop, and also includes a temperature detection device for detecting temperature conditions, wherein the temperature detection device is located between the range hood and the cooktop;

[0009] When the range hood is a top-mounted type, the temperature detection device is installed on the upper part of the countertop where the cooktop is placed, and the installation distance between the temperature detection device and the countertop is 55-65cm, and the monitoring angle of the temperature detection device is 20-40 degrees.

[0010] When the range hood is a side-suction type, the temperature detection device is installed at the top of the countertop where the cooktop is placed, and the installation distance between the temperature detection device and the countertop is 35-45cm, and the monitoring angle of the temperature detection device is 40-60 degrees.

[0011] The temperature detection device includes a central control module, as well as a temperature measurement module, a display module, an alarm module, a power supply module, an activation module, a detection module, a parameter setting module, and a housing.

[0012] The central control module is electrically connected to the temperature measurement module for detecting real-time temperature, the display module for displaying information, the alarm module for alerting the user, the power supply module for supplying power, the start-up module for starting up, the detection module for detecting user activity, and the parameter setting module for setting temperature alarm thresholds.

[0013] The central control module is fixedly installed inside the outer casing, the temperature measuring module is fixedly installed on the lower front side of the outer casing, the display module is fixedly installed in the middle of the front of the outer casing, the battery compartment is located in the middle of the rear of the outer casing, the power module is installed inside the battery compartment, the activation module is installed on the upper left side of the outer casing, the parameter setting module is installed on the upper right side of the outer casing, the alarm module is connected to the outer casing, and the detection module is fixedly installed in the middle of the outer casing and located above the display module.

[0014] The central control module is wirelessly connected to the gas source control valve of the stove.

[0015] The central control module is wirelessly connected to the main control board of the range hood.

[0016] Furthermore, the central control module is a low-power MCU.

[0017] Furthermore, the temperature measurement module is an infrared temperature sensor.

[0018] Furthermore, the display module is an LCD display screen.

[0019] Furthermore, the alarm module includes an LED light and a buzzer, both of which are electrically connected to the central control module. The LED light is fixedly installed on the upper right side of the housing and is located above the display module, while the buzzer is fixedly installed on the right side of the housing.

[0020] Furthermore, the power module uses AA batteries.

[0021] Furthermore, the detection module is a PIR (Passive Infrared Sensor).

[0022] Furthermore, both the activation module and the parameter setting module are buttons, and multiple parameter setting modules are provided at equal intervals.

[0023] Compared with the prior art, the advantages of this utility model are as follows: When using this utility model, the installation position of the temperature detection device is different for different types of range hoods. When the range hood is a top-mounted type, the temperature detection device is installed at the top of the stove surface, and the installation distance between the temperature detection device and the surface is 55-65cm, and the monitoring angle of the temperature detection device is 20-40 degrees.

[0024] When the range hood is a side-suction type, the temperature detection device is installed at the top of the countertop where the cooktop is placed, and the installation distance between the temperature detection device and the countertop is 35-45cm, and the monitoring angle of the temperature detection device is 40-60 degrees.

[0025] The temperature detection device monitors the temperature at different locations in the pan in real time while cooking. The temperature measurement module detects the temperature inside the pan in real time and uploads it to the central control module. The central control module uploads the real-time temperature information to the main control board of the range hood. The main control board of the range hood adjusts the fan speed according to different preset temperature thresholds.

[0026] The central control module sends real-time temperature information to the display module for display. If the central control module detects that the temperature inside the pot exceeds the set temperature, the central control module determines that the pot is in a state of burning dry. The central control module first controls the alarm module to sound an alarm to notify the user. Then, the central control module shuts off the flame source through the gas source control valve of the stove to prevent a fire.

[0027] If the detection module detects that a user has left and uploads the duration of the absence to the central control module, and the central control module determines that the duration of the user's absence exceeds the threshold set in the system, it will issue an alarm through the alarm module to remind the user.

[0028] This invention enables real-time monitoring of the temperature at different locations inside the pan while cooking, and can control the fan speed of the range hood according to the pan's temperature. Furthermore, when the user leaves, this invention can detect when the pan is burnt dry and trigger an alarm to prevent accidents. Attached Figure Description
