Description

Technical Field

[0001] The invention relates to the technical field of gas safety equipment, and in particular to a smoke and stove linked range hood with an infrared temperature sensing safety device and a control method. Background Art

[0002] The existing smoke and stove linkage products can realize that when the gas stove is turned on, the range hood will start working synchronously. After the gas stove is turned off, the range hood will also turn off after working for a few minutes. It only realizes a simple synchronous on and off function. However, during the use of the gas stove at home, the user may forget to turn off the gas stove for a long time because the user is busy with other things, or watches TV, browses the mobile phone, plays games, etc., and the gas stove cannot send an alarm to the user and turn off the gas stove in time, causing the gas stove to burn for a long time, resulting in safety hazards such as dry burning and burning pots, causing fires, and even explosions. Or, the user temporarily goes out to pick up a courier or throw away garbage, etc., and is locked out of the door without the door key. No one is at home, but the gas stove is still burning, and the gas stove cannot be turned off in time. There are huge safety hazards.

[0003] Therefore, it is necessary to propose a new type of smoke-stove linkage range hood with an infrared temperature sensing safety device and a control method to solve the above problems, so as to solve the problem that traditional smoke-stove linkage products cannot remotely remind the user when the user forgets to turn off the fire. Summary of the invention

[0004] The present invention provides a range hood linked with a smoke and stove with an infrared temperature sensing safety device and a control method, which solves the problem that traditional range hood linked products cannot remotely remind the user when the user forgets to turn off the fire.

[0005] The technical problem solved by the present invention is achieved by adopting the following technical solutions: A range hood linked to a smoke and stove with an infrared temperature sensing safety device comprises a range hood and a gas stove. The range hood is provided with a power supply and an infrared temperature sensor for sensing the temperature of a heating vessel at the gas stove. The range hood is provided with a control system linked to the gas stove. The power supply and the infrared temperature sensor are electrically connected to the control system respectively. The infrared temperature sensor is also provided with a wireless transceiver for sending warning information to a mobile device.

[0006] Furthermore, it also includes a solenoid valve cut-off device for cutting off the gas, and the solenoid valve cut-off device is electrically connected to the control system.

[0007] Furthermore, the solenoid valve cut-off device is arranged at the gas inlet pipe of the gas stove.

[0008] Furthermore, it also includes a mobile device, which is used to receive the warning information sent by the infrared temperature sensor.

[0009] Furthermore, when the detected temperature reaches a first preset temperature, the wireless transceiver sends a warning message to the mobile device; when the detected temperature reaches a second preset temperature higher than the first preset temperature, the infrared temperature sensor feeds back information to the control system to control the gas stove to shut down.

[0010] Furthermore, the temperature sensing end of the infrared temperature sensor is oriented toward the position of the heating vessel of the gas stove.

[0011] A range hood control method, characterized by comprising the following steps: a. The range hood and gas stove are turned on, and the infrared temperature sensor starts working; b. The infrared temperature sensor detects the temperature of the gas stove heating vessel; c. When the detected temperature reaches a first preset temperature, the wireless transceiver sends a warning message to the mobile device.

[0012] Furthermore, the method further includes the following steps: d. when the detected temperature reaches a second preset temperature higher than the first preset temperature, the infrared temperature sensor feeds back information to the control system to control the gas stove to shut down.

[0013] Furthermore, the method further comprises the following steps: e. when the detected temperature reaches the second preset temperature, the wireless transceiver sends a warning message to the mobile device.

[0014] Furthermore, the control system controls the gas stove to be shut down by controlling the solenoid valve cut-off device to close the gas inlet pipe of the gas stove.

[0015] The present invention has the following beneficial effects: The present invention provides a rod groove at the bottom of the board body, and the rod groove is used to store the support rod. The bottom of the board body is provided with a rod insertion hole. When one end of the support rod is inserted into the rod insertion hole, the other end of the support rod is fixed in the rod insertion hole to support the board body. The side without the support rod is placed on the door edge and the armrest saddle to bear the force, and the side with the support rod can support the table top in the central control or the cup groove of the central control, thereby solving the problems that the traditional vehicle-mounted table top relies on the table leg accessories in the accessory bag for support, resulting in limited support height, inability to be used in positions with large height differences, the table top is suspended in the central control position, the support rod is easy to be lost, and the use effect is poor.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below with reference to specific diagrams.

[0021] See also Figure 1 and Figure 2 A smoke and stove linkage range hood with an infrared temperature sensing safety device comprises a range hood 1 and a gas stove 2. The range hood 1 is provided with a power supply and an infrared temperature sensor 3 for sensing the temperature of the position of the heating vessel of the gas stove 2. The range hood 1 is provided with a control system 4 for linkage control with the gas stove 2. The power supply and the infrared temperature sensor 3 are electrically connected to the control system 1 respectively; the infrared temperature sensor 3 is also provided with a wireless transceiver 5 for sending warning information to a mobile device. When the temperature detected by the infrared temperature sensor 3 reaches a first preset temperature, the wireless transceiver 5 sends a warning message to the mobile device 7; when the detected temperature reaches a second preset temperature higher than the first preset temperature, the infrared temperature sensor 3 feeds back information to the control system 4 to control the gas stove 2 to turn off. In this way, the user can be remotely reminded to turn off the gas stove 2 when dry burning occurs, and the gas stove 2 can be automatically turned off when the user does not take any action and further danger occurs.

[0022] The electromagnetic valve cut-off device 6 for cutting off the gas is also included, and the electromagnetic valve cut-off device 6 is electrically connected to the control system 4. In this way, the gas stove 2 can be turned off by the electromagnetic valve cut-off device 6.

[0023] The solenoid valve cut-off device 6 is arranged at the gas inlet pipe of the gas stove 2. In this way, the gas stove 2 can be turned off by cutting off the gas inlet through the solenoid valve cut-off device 6.

[0024] It also includes a mobile device 7, which is used to receive the warning information sent by the infrared temperature sensor 3. In this way, the warning information can be obtained by using the mobile device 7, thereby realizing remote reminder.

[0025] When the detected temperature reaches the first preset temperature, the wireless transceiver 5 sends a warning message to the mobile device 7; when the detected temperature reaches the second preset temperature higher than the first preset temperature, the infrared temperature sensor 3 feeds back information to the control system 4 to control the gas stove 2 to turn off. In this way, the user can be remotely reminded to turn off the gas stove 2 when dry burning occurs, and the gas stove 2 can be automatically turned off if the user does not take any action and further danger occurs.

[0026] The temperature sensing end of the infrared temperature sensor 3 faces the position of the heating dish of the gas stove 2. In this way, the gas danger can be accurately judged.

[0027] A range hood control method, characterized by comprising the following steps: a. The range hood and gas stove are turned on, and the infrared temperature sensor starts working; b. The infrared temperature sensor detects the temperature of the gas stove heating vessel; c. When the detected temperature reaches a first preset temperature, the wireless transceiver sends a warning message to the mobile device.

[0028] The method also includes the following steps: d. when the detected temperature reaches a second preset temperature higher than the first preset temperature, the infrared temperature sensor feeds back information to the control system to control the gas stove to shut down.

[0029] The method further comprises the following steps: e. when the detected temperature reaches the second preset temperature, the wireless transceiver sends a warning message to the mobile device.

[0030] The control system controls the gas stove to be shut down by controlling the solenoid valve cut-off device to close the gas inlet pipe of the gas stove.

[0031] When in use, the infrared temperature sensor 3 is installed just above the range hood 1 linked with the range hood and stove, and is connected to the control system 4 of the range hood 1, and the range hood 1 provides power. When the gas stove 2 linked with the range hood and stove is turned on, the range hood 1 starts to work synchronously, and the infrared temperature sensor 3 starts to work, sending an infrared temperature detection signal to the position of the heating vessel of the gas stove 2, and continuously dynamically detecting its temperature. When the water in the vessel is dried up, or the fire is forgotten to be turned off, the temperature continues to rise. When the infrared temperature senses that the temperature reaches the first preset temperature, it will be fed back to the control system 4, and a warning message will be pushed to the user from the APP of the mobile device 7 to remind the user whether he has forgotten to turn off the gas stove 2. When the user receives the prompt message, he realizes that the gas stove 2 in the kitchen is still working, and will enter the kitchen in time to check or turn off the valve of the gas stove 2. If the user fails to get to the kitchen in time, the second preset temperature is set. When this temperature value is reached, the range hood 1 sends a signal to the gas stove 2 to cut off the solenoid valve to turn off the gas stove 2. At the same time, in order to meet the needs of more users, a universal solenoid valve cut-off device 6 can also be separately adapted to connect to the front section of the gas intake pipe. When the above situation occurs, the same working principle can be used to cut off the gas stove 2 and automatically shut down the gas stove 2, thereby achieving the purpose of eliminating hidden dangers.
