The remote control module 5 includes a third microprocessor 51, a third antenna 52 connected to the third microprocessor 51, and two control buttons 53 for controlling the third microprocessor 51. The third microprocessor 51 can perform wireless network communication with the first communication unit 32 via the third antenna 52. The control buttons 53 are respectively pressed to respectively drive the third microprocessor 51 to send a shutdown signal and a cancellation signal via the third antenna 52. The functions of the shutdown signal and the cancellation signal are described later.

The following is a description of the operation between the modules of the wireless network type safety gas furnace device of the present invention.

When the wireless network type safety gas furnace device is used, when the ignition switch 313 is driven to drive the electromagnetic valve 32 to open to release the gas for ignition, the ignition switch 313 also turns on the battery unit 33 and the first The communication unit 32 triggers the first communication unit 32 to execute the normal mode. At this time, the first microprocessor 321 sends a first confirmation signal via the first antenna 324 every predetermined time, for example, every 1 second, the gas sensing module 4 and the remote control module 5 The first confirmation signal is separately received and recognized.

After receiving the first confirmation signal, the second microprocessor 431 drives the second alarm 432 to output the second confirmation message, thereby indicating the communication control function of the first communication unit 32. Normally, the solenoid valve 312 can be closed by control. Then, the second microprocessor 431 also sends a second confirmation signal via the second antenna 433. The first microprocessor 321 receives the second acknowledgement signal via the first antenna 324, and then drives an LED 323 of the first alert 322 to issue the first acknowledgement message. In this embodiment, the first confirmation message is a warning light number. Therefore, the gas sensing module 4 can normally send signals to control the stove module 3.

After receiving the first confirmation signal, the third microprocessor 51 of the remote control module 5 receives a third confirmation signal correspondingly. The first microprocessor 321 receives the third confirmation signal via the first antenna 324, and then drives the other LED 323 of the first indicator 322 to output the third confirmation message, thereby indicating the remote control module 5 The communication function is normal, and the first communication unit 32 can be remotely closed by the remote control module 5 to close the electromagnetic valve 312.

When the stove body 31 is normally turned off and the flame is turned off, that is, when the ignition switch 313 directly closes the solenoid valve 312, the first communication unit 32 sends a flameout signal before powering down to stop the operation. The second communication unit 43 and After receiving the flameout signal, the remote control module 5 stops transmitting the second confirmation signal and the third confirmation signal respectively. At this time, the furnace module 3, the gas sensing module 4 and the remote control module 5 are normally broken. News.

When the solenoid valve 312 of the stove body 31 is turned on, if the user does not hear or see the first confirmation message and/or the second confirmation message, it indicates that the first communication unit 32 or the second communication unit 43 may be faulty. For example, the battery unit 33 is de-energized so that the first communication unit 32 cannot transmit the first confirmation signal, so the second communication unit 43 does not report the second confirmation signal, or the second communication unit 43 fails. Thereby, the user can immediately know that the first communication unit 32 or the gas sensing module 4 may be faulty and can be repaired immediately. If the first communication unit 32 and the second communication unit 43 have abnormally disconnected after the initial communication confirmation is completed, that is, when the other communication signal is not received, for example, one of the two is damaged or the stove module 3 is damaged. The battery unit 33 is depleted, and the undamaged first communication unit 32 drives the other LED 323 of the first indicator 322 to output a runaway message, or the undamaged second communication unit 43 drives the second indicator 432 to output a Out of control messages to alert users to pay attention. When the third microprocessor 321 does not receive the third confirmation signal, the other LED 323 of the first indicator 322 also drives an uncontrollable message. In this embodiment, the aforementioned runaway message and the remote control message may be a light, a sound, or a combination of the two.

The first communication unit 32 can confirm whether the gas sensing module 4 and the remote control module 5 are functioning normally through the wireless network, and the gas sensing module 4 can also confirm whether the stove module 3 is normal through the wireless network. The two-way confirmation design is convenient for the user to use the first confirmation message and the third confirmation message outputted by the first warning device 322 to know that the second communication unit 43 and the remote control module 5 are in the process of using the safety gas furnace device. The normal state of the first communication unit 32 can be remotely controlled, and the second confirmation message sent by the second alarm 432 of the gas sensing module 4 can be used to understand that the stove module 3 is in a normal state of acceptable control. The safety of use of the safety gas furnace device can be greatly improved.

Next, the operation mode of the safety gas furnace device when the gas leakage of the stove module 3 occurs is further explained.

When the gas sensor senses the gas, a sense signal is outputted, and the second microprocessor 431 is driven by the sense signal to drive the gas alarm 42 to emit a gas leak message. Remind the surrounding personnel to take necessary measures, such as opening the window, away from the scene, etc., while the second microprocessor 431 also sends a shutdown signal via the second antenna 433. The first microprocessor 321 receives the shutdown signal via the first antenna 324 and is driven by the shutdown signal to perform the emergency mode. When the first microprocessor 321 executes the emergency mode, the solenoid valve 312 is driven to close and the solenoid valve 312 is locked and can no longer be driven to open, thereby preventing the gas from continuing to leak. The solenoid valve 312 is again opened.

In addition, when the gas alarm 42 sends out a gas leak message, if the second communication unit 43 fails and the first communication unit 32 is not driven to close the electromagnetic valve 312, the danger is avoided in order to avoid the environment leaking from the gas. After the remote control module 5 leaves the stove module 3 for a distance, the predetermined control button 53 of the remote control module 5 is pressed to issue the shutdown signal, thereby driving the first communication unit 32 to immediately perform an emergency. The mode closes and locks the solenoid valve 312. In addition, the cancellation signal can also be sent by pressing another control button 53. The second microprocessor 431 can receive the cancellation signal via the second antenna 433, and is driven by the cancellation signal to turn off the gas alarm 42. .

When the emergency mode of the first microprocessor 321 is to be released, the power of the battery unit 33 can be interrupted by turning off the ignition switch 313, and the first communication unit 32 can be powered off and reset, thereby releasing the first micro. The emergency mode of the processor 321 causes the solenoid valve 312 to be opened again.

As shown in FIG. 4, the second preferred embodiment of the wireless network type gas furnace apparatus of the present invention differs from the first embodiment in the structural design of the stove module 3. For convenience of explanation, only the differences from the first embodiment will be described below.

In this embodiment, the battery unit 33 is directly electrically connected to the first communication unit 32, and the first communication unit 32 is continuously powered to enable the first communication unit 32 to sense the gas at intervals. The module 4 and the remote control module 5 communicate with each other to confirm whether the functions of each other are normal at any time, and can notify the user immediately when one of them fails.

In addition, the stove module 3 further includes a reset switch 34 mounted on the stove body 31 and connected to the first microprocessor 321, and the reset switch 34 can be driven to drive the first microprocessor. 321 returns from emergency mode to normal mode. That is, when the first microprocessor 321 executes the emergency mode to lock the battery valve 312, the emergency mode can be released by driving the reset switch 34, so that the solenoid valve 312 can be turned on again.

In summary, the first communication unit 32 of the stove module 3, the second communication unit 43 of the gas sensing module 4, and the remote control module 5 can communicate with each other through a wireless network to confirm each other. Whether the controlled function is normal or not, the user can immediately know whether the gas sensing module 4 and the remote control module 5 are normal and whether the stove module 3 can be normally controlled during the process of using the safe gas furnace device of the present invention. And the first communication unit 32 and the gas sensing module 4 respectively can respectively send out a control signal for reminding the user when a single abnormal interruption occurs during the use of the stove body 31, so that the user can immediately perform maintenance. The safety of the safety gas furnace device can be greatly improved. Moreover, the design of the remote control module 5 can facilitate the user to remotely close the electromagnetic valve 312 and the gas alarm 42 at the remote end after being remote from the gas leakage site, thereby further ensuring the safety of the user, which is quite convenient and practical. Therefore, the object of the present invention can be achieved.
