Abstract
Description
[Technical Field]
[0001] This utility model relates to an automatic timed flameout gas stove. [Background Technology]
[0002] Existing gas stoves do not automatically shut off after ignition; they can only be shut off manually by turning off the gas. Therefore, if the user forgets to turn off the gas stove, the continued combustion can easily cause a fire risk. [Utility Model Content]
[0003] This invention overcomes the shortcomings of the prior art and provides an automatic timed flameout gas stove.

The burner is connected to an ejector channel pipe communicating with the combustion chamber. The other end of the ejector channel pipe is connected to a gas valve. The gas valve is equipped with a gas ignition and regulating switch and a gas solenoid valve. The pulse controller is connected to the display, the ignition needle, the gas ignition and regulating switch, and the gas solenoid valve to control the ignition needle to ignite after receiving the ignition signal from the gas ignition and regulating switch. After ignition, the pulse controller displays a countdown time on the display and controls the gas solenoid valve to shut off the gas and extinguish the flame after the countdown ends.
[0006] The automatic timed flameout gas stove described above is characterized in that: the burner is equipped with a sensing needle connected to a pulse controller for detecting whether ignition has occurred.
[0007] An automatic timed flameout gas furnace as described above is characterized in that: the combustion chamber includes an outer combustion chamber and an inner combustion chamber, the ejector channel pipe includes an outer ejector channel pipe and an inner ejector channel pipe respectively communicating with the outer combustion chamber and the inner combustion chamber, and the gas valve is respectively connected to the outer ejector channel pipe and the inner ejector channel pipe.
[0008] The automatic timed flameout gas furnace described above is characterized in that: an external combustion chamber fire force valve is provided between the external injection channel pipe and the gas valve.
[0009] The automatic timed flameout gas furnace described above is characterized in that: an internal combustion chamber fire control valve is provided between the internal ejector channel pipe and the gas valve.
[0010] An automatic timed flameout gas stove as described above is characterized in that: it further includes a panel, a gas valve is located at the bottom of the panel, and a gas ignition and adjustment switch extends through the gas valve.
[0011] The automatic timed flameout gas stove described above is characterized in that: a display is mounted on the panel.
[0012] The beneficial effects of this utility model are:
[0013] The pulse controller of this utility model controls the ignition needle to ignite after receiving the ignition signal from the gas ignition and regulating switch. After ignition, it displays the countdown time on the display and controls the gas solenoid valve to shut off the gas and extinguish the flame after the countdown ends. This realizes the automatic countdown and extinguishing function after ignition, and improves the safety of gas stove use. [Image Description]
[0014] Figure 1 This is a schematic diagram of the structure of this utility model. [Detailed Implementation]
[0015] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.
[0016] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indication will also change accordingly. Furthermore, descriptions involving "preferred," "second-best," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "preferred" or "second-best" may explicitly or implicitly include at least one of those features.
[0017] like Figure 1As shown, an automatic timed flameout gas stove includes a burner 1, a pulse controller 2, and a display 3. The burner 1 has a combustion chamber 4, and an ignition needle 5 is installed inside the combustion chamber 4. The burner 1 is connected to an ejector channel pipe 6 communicating with the combustion chamber 4. The other end of the ejector channel pipe 6 is connected to a gas valve 7. The gas valve 7 is equipped with a gas ignition and regulating switch 8 and a gas solenoid valve 9. The pulse controller 2 is connected to the display 3, the ignition needle 5, the gas ignition and regulating switch 8, and the gas solenoid valve 9 respectively. Upon receiving an ignition signal from the gas ignition and regulating switch 8, the pulse controller 2 controls the ignition needle 5 to ignite the gas, displays a countdown time on the display 3 after ignition, and controls the gas solenoid valve 9 to shut off the gas and extinguish the flame after the countdown ends. The countdown time is typically set to 30 minutes. In practical applications, after the gas ignition and regulating switch 8 sends an ignition signal to the pulse controller 2, the pulse controller 2 controls the ignition needle 5 to ignite. After ignition, the pulse controller 2 displays a 30-minute countdown timer on the display 3. After the countdown ends, the pulse controller 2 controls the gas solenoid valve 9 to shut off the gas input, achieving automatic timed flameout after ignition and improving safety. In this case, the countdown timer of the gas stove can also be set by different methods such as long press, short press, and multiple presses, and different countdown timer settings can be set according to actual application needs.
[0018] like Figure 1 As shown, the burner 1 is equipped with a sensing needle 10 connected to the pulse controller 2 to detect whether ignition has occurred. The sensing needle 10 detects whether the ignition needle 5 has been successfully ignited, and after successful ignition is detected, the pulse controller 2 displays a 30-minute countdown time on the display 3.
[0019] like Figure 1 As shown, the combustion chamber 4 includes an outer combustion chamber 41 and an inner combustion chamber 42. The ejector channel pipe 6 includes an outer ejector channel pipe 61 and an inner ejector channel pipe 62 that are respectively connected to the outer combustion chamber 41 and the inner combustion chamber 42. The gas valve 7 is connected to the outer ejector channel pipe 61 and the inner ejector channel pipe 62 to realize the heating function of the outer ring fire and the center fire.
[0020] like Figure 1 As shown, an external fire valve 13 for the external combustion chamber 41 is provided between the external ejector channel pipe 61 and the gas valve 7; an internal fire valve 11 for the internal combustion chamber 42 is provided between the internal ejector channel pipe 62 and the gas valve 7 to adjust the air input, thereby adjusting the mixture ratio of gas and air.
[0021] like Figure 1 As shown, it also includes a panel 12, a gas valve 7 located at the bottom of the panel 12, and a gas ignition and adjustment switch 8 extending through the gas valve 7. A display 3 is located on the panel 12, which is centrally located and improves the overall aesthetics.
[0022] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
