Gas furnace protection

The present invention relates to a gas stove protection device, and particularly relates to a warning signal that can be used to remind a user by using a sensing device carried by a user when the user is away from the gas furnace and the fire of the gas furnace is not turned off. Eli automatically remotely or return the switch that shuts down the gas stove to ensure the safety of the gas furnace.

The gas stove is the main tool for cooking in the kitchen, which can be heated to boil water or stewed. However, since the gas burner uses the method of burning gas to generate a fire flame for heating food, if it is not prepared for safety and is prepared for safety protection, the gas furnace can easily dry the liquid in the cookware and occur. The dangerous situation of empty burning, or the liquid that is overflowed by the fire, is leaked out, causing gas to leak out, forming a source of disaster. For the traditional practice of safety protection during the use of gas stoves, the cooking alarm clock is generally used. Before the gas stove is turned on, the cooking alarm clock is set for the time. When the set time arrives, the cooking alarm clock can give a warning sound signal to Remind the user to turn off the switch of the gas stove. However, the cooking alarm clock only has the function of reminding; if the user has an emergency to go out or sleep, and forget to turn off the gas stove switch; or the old man does not turn off the gas burner switch because he cannot hear the warning signal; or the user forgets that he is using gas It is a dangerous situation to cook food or boil water without shutting down the gas stove switch.

Therefore, there is already a gas timing technology that can automatically shut off gas on the market, such as Taiwan Announcement No. 296040 "Automatic Timing Device for Gas Furnace" and Taiwan Announcement No. 529699 "A Self-Assembleable Gas Furnace Switch Timing Device" Patent Case Mainly to install the timing (time) components of the gas in the gas furnace switch, or at the gas source end of the gas barrel end or the main switch end of the natural gas household (not for each gas stove switch) to control the gas stove switch and gas. The opening and closing timing of the source end. The gas timing (timekeeping) member is capable of accepting a time for the user to set the gas burner for boiling boiled water or stewing the food. When the time is up, the gas timing (timekeeping) member can automatically close the gas burner switch or the gas source end to stop the supply. Gas, to automatically extinguish the fire, to avoid forgetting to shut down the gas stove.

However, the disadvantage is that when the user has to go out or sleep in a hurry and forget to close the gas stove, if the set time (time of the time) of the gas timing (timekeeping) member is not reached, the gas furnace will continue unattended. The dangerous situation of supplying fire is prone to fire. Moreover, when the gas timing (timekeeping) member automatically closes the gas source head, the switches of the gas furnaces are not turned off. At this time, if the gas timing (timekeeping) member is turned on again, and the gas source end is opened, the gas will be directly caused by the gas source.

The trigger is operated again, and the time delay 33 can accept the time when the user sets the delay. If the user goes out and does not turn off the fire of the gas stove 1, and the second sensor 22 of the belonging item 9 (for example, the mobile phone 91) makes the second sensor as the user leaves the sensing range. When the first sensor 21 fails to sense with the first sensor 21, the warning unit 301 of the second protection module 30 can issue a warning signal to remind the user to return to the switch 11 that closes the gas furnace 1, the gas furnace 1 The first sensor 21 can also trigger the time delay unit 33 to cause the time delay unit 33 to count the set time. When the set time of the time delay unit 33 is counted, the first sensor 21 triggers the driving unit. 32 automatically closes the switch 11 of the gas furnace 1. When the user returns to the room for a short time (for example, receiving a letter or dumping garbage), or when the user counts the set time of the time delay device 33, the user returns to the sensing range, so that the user The first sensor 21 and the second sensor 22 are again sensed from each other, and the time delay 33 stops counting, so that the gas furnace 1 switch 11 is maintained in a state in which the supply fire is turned on.
