[ detailed description ] A
In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.
First, referring to fig. 1, fig. 1 is a schematic view of a gas stove according to an embodiment of the present invention. The gas stove 1 comprises a burner 2 and an ignition needle 300 connected into an ignition loop, wherein the ignition needle 300 is provided with a discharge end 301, and the discharge end 301 is actually a part of an ignition electrode exposed outside an insulating shell of the ignition needle 300. The discharge end 301 discharges to form an electric spark or arc. The user issues an ignition command through an ignition switch to control the ignition circuit, thereby controlling whether the ignition needle 300 ignites or not. An ignition switch is arranged on a panel of a gas stove, and is turned on through touch operation; the ignition switch can also be turned on by pressing down the knob.
The burner 2 comprises a burner head 3 and a burner base 4. The burner 3 is detachably placed on the burner base 4. The ignition needle 300 is mounted on the burner mount 4. Specifically, the burner 3 includes a fire cover base 20 and a fire cover 10 covering the fire cover base 20. In this embodiment, the fire cover 10 comprises an inner ring fire cover 11 and an outer ring fire cover 12, and the outer ring fire cover 12 surrounds the outer periphery of the inner ring fire cover 11. The inner ring fire cover 11 is provided with a fire outlet 110, the outer ring fire cover is provided with a fire outlet 120, and the fuel gas flowing out from the fire outlets 110 and 120 is ignited to form flame. The inner ring fire cover 11 and the outer ring fire cover 12 are respectively covered on the fire cover base 20, and an inner ring cavity and an outer ring cavity for containing gas are respectively formed on the inner ring fire cover 11 and the outer ring fire cover base 20, the fire outlet 110 is communicated with the inner ring cavity, and the fire outlet 120 is communicated with the outer ring cavity. In this embodiment, the stove head 3 includes three independently movable components, i.e. an inner ring fire cover 11, an outer ring fire cover 12 and a fire cover base 20. The three parts are independent parts and can be moved, installed and disassembled respectively.
The fire cover base 20 of the present embodiment is provided with a protection cover 201, and the protection cover 201 shields the discharge end 301 in a use state.
The gas range 1 of the present embodiment further comprises a trigger 400 and a switch 500, wherein the trigger 400 is configured to trigger the switch 500 to generate a trigger signal for controlling the ignition circuit to be conducted. Specifically, in the embodiment, the triggering member 400 includes a rod 401 capable of moving up and down elastically, and when the rod 401 moves up and down, the rod 401 enables the switch 500 to generate the triggering signal, or releases the switch 500 to stop generating the triggering signal. The gas range 1 further includes a spring 600 disposed in one of the mounting grooves. The rod 401 is connected or abutted to the spring 600 so as to be elastically movable up and down. The trigger 400 further comprises an arm 402 disposed on the rod 401 and intersecting the rod 401. Switch 500 is a microswitch that includes a reed 501. The trigger 400 is triggered, i.e. the rod 401 is pressed down to its arm 402 to apply a force on the reed 501, so that the end of the reed 501 is connected with the fixed contact on the microswitch, thereby closing the microswitch.
The protective cover 201 of the present embodiment is disposed on the fire lid base 20, and the fire lid base 20 has a first position, which is the position of the fire lid base 20 shown in fig. 1. When the fire cover base 20 is placed at the first position, the fire cover base 20 is installed in place, the protection cover 201 covers the discharge end 301 right above the discharge end 301, and meanwhile, the fire cover base 20 triggers the trigger 400. That is, when the fire cover base 20 is installed at the first position, the protective cover 201 is covered directly above the discharge end 301 (as shown in fig. 1), the fire cover base 20 presses the rod 401 downward to make the rod 401 drive the arm 402 to move downward, i.e. to move in the X direction, and the arm 402 acts on the reed 501 of the micro switch to close the micro switch. Thus, the ignition circuit is turned on. When a user turns on the ignition switch, the ignition needle 300 ignites, and the discharge end 301 discharges to generate electric sparks or continuous electric arcs. Since the protection cover 201 covers the discharge end 301 right above the discharge end 301, the user does not touch the discharge end and is not injured.
When the user cleans the gas range, the fire cover base 20 is removed, so that the discharge end 301 of the ignition needle 300 is exposed without being shielded by the protective cover 201, but at the same time, the trigger 400 is not triggered because the fire cover base 20 is removed. The specific process is as follows, the rod 401 automatically moves upwards under the restoring force of the spring 600, namely moves towards the opposite direction of X, the arm 402 moves upwards along with the rod and then disengages from the microswitch, and the microswitch is turned off, so that the ignition circuit is controlled to be turned off. Even if the user carelessly turns on the ignition switch, the ignition needle does not ignite because the ignition circuit is in the off state. The user is not injured.
Compared with other embodiments, the present embodiment has a further advantage that the fire cover base 20 provided with the protection cover 201 is also used for triggering the triggering member 400, such design has little change to the structure of the burner, and the protection cover can be integrally formed on the fire cover base without additional fixing or connecting steps.
Referring to fig. 2, fig. 2 is a schematic view of a gas cooker according to another embodiment of the present invention. The same structure in this embodiment as that in the embodiment shown in fig. 1 is denoted by the same reference numeral, and the functions are the same or similar, which are not described again. The difference from the embodiment shown in fig. 1 is that the protective cover 111 of the present embodiment is disposed on the inner ring fire cover 11, and the inner ring fire cover 11 further includes a protrusion 112.
The inner ring fire cover 11 has a second position, when the inner ring fire cover 11 is placed at the second position, that is, when the inner ring fire cover 11 is installed in place, the protection cover 111 shields the discharge end 301 directly above the discharge end 301, and the protrusion 112 of the inner ring fire cover 11 triggers the trigger 400. Namely, when the inner ring fire cover 11 is installed at the second position, the protective cover 111 is arranged right above the discharge end 301 (as shown in fig. 2); at the same time, the protrusion 112 of the inner ring fire cover 11 presses the rod 401 downwards, so that the rod 401 carries the arm 402 to move downwards, and the arm 402 acts on the reed 501 of the micro switch, so that the micro switch is closed. Thus, the ignition circuit is turned on. When a user turns on the ignition switch, the ignition needle 300 ignites, and the discharge end 301 discharges to generate electric sparks or continuous electric arcs. However, since the protective cover 111 covers the discharge end 301 directly above the discharge end 301, the user does not touch the discharge end and is not injured.
When a user cleans the gas stove, the inner ring fire cover 11 is removed from the second position, the discharge end 301 of the ignition needle 300 is exposed and is not shielded by the protective cover 201, but meanwhile, the trigger 400 is not triggered because the protruding portion 112 is removed, the ignition circuit is disconnected, and the discharge end cannot discharge. The specific process is as follows, the rod 401 automatically moves upwards under the restoring force of the spring 600, the arm 402 moves upwards along with the upward movement and is disengaged from the micro switch, and the switch 500 is turned off, thereby controlling the ignition circuit to be turned off. Even if the user turns on the ignition switch, the ignition needle cannot ignite as the ignition circuit is in the off state.
Compared with other embodiments, the present embodiment has a further advantage in that the protective cover 111 and the protrusion 112 for triggering the triggering member 400 are both disposed on the inner ring fire cover 11, and the protective cover 111 and the protrusion 112 can be integrally formed on the inner ring fire cover without performing an additional fixing or connecting step.
Referring to fig. 3 again, fig. 3 is a schematic view of a gas stove according to another embodiment of the present invention. The same structure in this embodiment as that in the embodiment shown in fig. 1 is denoted by the same reference numeral, and the functions are the same or similar, which are not described again. The difference from the embodiment shown in fig. 1 is that the protective cover 111 is disposed on the inner ring fire cover 11, and the inner ring fire cover 11 is fixed with the fire cover base 20. The fire lid base 20 has a first position and the inner ring fire lid 11 has a second position. When the fire cover base 20 is placed at the first position, the inner ring fire cover 11 is located at the second position, and the fire cover base 20 triggers the trigger 400, the protection cover 111 shields the discharge end 301 right above the discharge end 301.
When the fire cover base 20 is placed in the first position, the inner ring fire cover 11 is located in the second position, that is, when the fire cover base 20 is installed in place, the inner ring fire cover 11 is naturally installed in place. At this time, the fire cover base 20 triggers the trigger 400, and the protection cover 111 shields the discharge end 301 directly above the discharge end 301. The ignition loop is conducted, a user opens the ignition switch, and the ignition needle can ignite.
Since the fire cover base 20 and the inner ring fire cover 11 are fixed together and move integrally, when a user wants to remove/install one of them, the other must be removed/installed together. When the discharge end 301 of the ignition needle is not shielded by the protective cover 111, the trigger 400 is not triggered, and the ignition circuit is disconnected, so that ignition cannot be performed.
The above are only three embodiments, and the present invention can have more embodiments by changing and combining. For example, in another embodiment of the present invention, the protective cover is disposed on the outer fire cover 12, and the outer fire cover 12 has a third position. When the outer ring fire cover 12 is placed at the third position, that is, when the outer ring fire cover 12 is installed in place, the protection cover shields the discharge end 301 right above the discharge end 301, and the outer ring fire cover 12 triggers the trigger 400. When the outer ring fire cover 12 is removed, the discharge end 301 of the ignition needle is exposed, but the trigger 400 is not triggered, and the ignition circuit is disconnected, so that ignition cannot be performed. In a specific implementation manner, a protrusion may be disposed on the outer fire cover, and when the outer fire cover 12 is placed at the third position, the protrusion 112 triggers the triggering member 400.
For another example, in another embodiment of the present invention, the protective cover is disposed on the outer fire cover 12, the outer fire cover 12 is fixed with the fire cover base 20, the fire cover base 20 has a first position, and the outer fire cover 12 has a third position. When the fire cover base 20 is placed at the first position, the outer ring fire cover 12 is located at the third position, and at this time, the fire cover base 20 triggers the trigger 400, and the protection cover shields the discharge end 301 right above the discharge end 301. The outer ring fire cover 12 may be secured to the fire cover base 20 by screws or rivets or welding.
In another embodiment of the present invention, the switch may be a magnetic switch or an electro-optical switch, in addition to the illustrated microswitch.
