Description

Detailed Description of the Invention (Technical Field) The present invention provides a
This invention relates to technology for adjusting the flame of a burner etc. by switching it with a switch.

(Background Art) Conventionally, for example, in a gas stove, the size of the flame of the jffff-ner is adjusted by a rotary adjustment knob provided on the front surface. For this reason, when making the flame smaller, you may turn the adjustment knob too much and end up extinguishing the flame.Also, because a d-pot is placed on the gas burner 112, you cannot see the flame, and it is difficult to turn the adjustment knob or sweetness. I had to do it while looking under the pot, etc., which was a bad technique.

Therefore, we were able to eliminate the need to discontinuously change the flame to a predetermined size using a push-in flame switching switch, but the flame changes rapidly and discontinuously from a large flame state to a small flame state. When this switch is made, there is a risk that the flame of the gas burner will go out because the amount of gas supplied to the gas burner is drastically reduced, and if this is left unnoticed, there is a problem that it may lead to a gas leakage accident.

(Object of the Invention) The present invention has been made in view of the background art described in Section 2, and its purpose is to easily change the size of the flame by using a push-type flame selection switch. To provide a flame adjustment device for a bathroom appliance that can be set to a predetermined size, is easy to use, and is free from the fear of extinguishing the flame due to sudden change to a small flame state.

(Disclosure of the Invention) The flame adjustment device for a gas appliance of the present invention is a gas appliance that has a plurality of push-in flame changeover switches for switching the flame size of a gas burner in multiple stages, and the flame adjustment device is a gas appliance that has a plurality of push-type flame changeover switches for switching the flame size of a gas burner in multiple stages. It is equipped with an anti-moxibustion tlI mechanism that prevents the flame changeover switch from being pushed beyond a predetermined number of steps when switching to the flame changeover switch.This achieves the above objectives and ensures ease of use and safety. It became so.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, although the case of a J5 stove will be described as an example, it goes without saying that other gas appliances may be used.

Figures 1 and 2 show the normal ru1 and plane of the cast iron (5), with cast burners (1) provided on the left and right sides of the upper surface, respectively, and a cylinder (2) for grilling fish etc. in the center of the front. is provided. This gas stove is operated by push-off type (so-called piano touch) switches, and the right switch group (A) is connected to the right No. 5 burner (1).
The left switch group 0 operates the left gas burner (ll), which are the ignition switch (3), large fire switch (4), and medium heat switch (5).
It consists of a small fire switch (6), a light fire switch (7), and a fire extinguishing switch (8), and a large fire switch (4).
478 rear changeover switches are made up of a medium heat switch (δ), a small fire switch (6), and a simmering fire switch (7). In addition, i9H+o)u is a switch for ignition and extinguishment of the krill (121 is a switch for opening the door (11) of the krill (2)).

The invention is implemented in a part for a gas burner (1). First, when the ignition switch (3) is pushed all the way in, the main pulp 03) opens and the pilot pulse circle for the pilot burner (not shown) also opens, and the ignition device (not shown) that continuously discharges electricity. ) by pie l]
・The burner is lit. Also, in conjunction with the pushing action of the famous dog switch (3), the big fire switch (4) is also turned on.
Great Fire Paroo 5 [+ω opens and fj Subarna f+]
is ignited by the pilot burner in a state of large flame.

After this, when you release your finger that had been pushing in the ignition switch (3), the ignition switch (3) and the fire switch (4) will go down a little, and the main burner C (1)
3) and the large fire pulp (15) remain open, and only the pilot pulse 04) is closed to extinguish the pilot burner.
The 25 burner (11) can be used in the state of a large fire.Next, when the medium heat switch (5) or the small fire switch (6) is pushed in, the ignition switch (3) is maintained in the closed state, but
The large fire switch (4) returns to its original state, and the medium flame Pulzu αG) or the small flame Pulzu 07) opens, and the flame of the gas burner (1) becomes medium flame or small flame. In this way, the large fire, medium heat, and small fire are controlled by the large fire switch (4) and the medium fire switch (5), respectively.
and the small fire switch (6). However, if you switch directly from a large or medium flame to a low flame with the smallest flame, there is a risk that the flame of the gas burner [1] will go out. You can't press it unless you press and turn on the small fire. In the last example, if you push in the fire extinguishing switch (8), all switching pulses (Ir+l (l(il Q)
η(18) is closed and the fusu is double-stitched.

Since then, I have given up on the specific invitation to perform the second work. As shown in FIG.

In 161, the cam pawl (51) is 4P; I locking side @ 4] K hits and stops, and the main pulse is closed (I: 11 is maintained in the gate-like Q-down position, and the slide bar '-β'O for large fire is)] Mu nails (4!
il hits the second locking edge (60) and stops, maintaining the flame of the gas burner (1) at a large flame.At this time, the pilot valve (14) is closed and the pilot-burner T is extinguished, and the interlocking piece (K between 521 and interlocking claw f5 [fl)
rJ, ■-11 II) I'll have a flash of 1t. Next, when you press the medium heat switch (5), the medium heat slide bar (the layer moves backwards, the cam claw (4+;) pushes the third sloped side (G8), and the gum board 31) moves to the left. Since the large fire cam claw (4!l) is removed from the second locking side of the width plate ((to) and returned to its original position, the medium heat pulp Qt is moved by the medium heat slide bar Asahi C38. ) to open, and the flame changes from large to medium heat.Furthermore, press the medium heat switch (5
), the medium heat cam pawl (46) pushes the gg3 lock release oblique side (70) and releases the cam plate () to the second locking side j6.
Since the large fire slide bar (37j) is moved by a distance 1ltC (c>b) which is larger than the width l of the first locking side (64I) Since the displacement mIJ distance c (c × d) is larger, the main pulse ``jα3) is kept open.In this way, when it is set to a large fire state or a medium fire state, the Toro Okawa cam The claw (46) is engaged with the push lock side g4) of the cam hole 9), making it impossible to push in the simmering switch (7) and making it impossible to switch the flame from a large or medium flame to a simmering flame. .Next, if you press the large fire switch (4) or the small fire switch (6), the same operation as above will occur and the flame will switch from medium to large or fd: /j\fire. .However, the width a of the cam hole for small fire (5th shallow fourth locking side (the width a of the hole is formed short and the push-in opening/y side 04) is the same as the width a of the cam hole (push-in D-tsuk). (It may be shorter than 1161 of side (I4)), so when the cam pawl (16) engages with the fourth locking side (7 (to) and is set to a small flame, the cam plate (31) ) has not returned sufficiently to the right,
Toro Okawa's cam claw (46! r/i push lock side (
74j and is unlocked. Therefore, when the simmering switch (7) is pushed in with a small flame, the fifth inclined side (7) is pushed by the cam pawl (41i) and the cam plate (31) moves by b. Then, the cam claw (9) of the small flame comes off from the 4th section upper edge copying and the slide bar ((!l) returns, and the simmering valve θ8) is pushed open by the slide bar (40) of the simmering flame, and the flame starts. is switched from a small flame to a simmering flame.Although the cam hole (59) of Shichiro Okawa is not provided with a lock release oblique side, the gas flow Ji1 is small for both the simmering flame and the cam hole (59) of the Shichiro Okawa. zu07) This is because there is no safety problem even if the Yoshitorobi no Pal "j08) is open at the same time.Also, if you press the large fire switch f (41) or the medium fire switch (5) from the state of Torookawa, the slide bar of Toro Okawa +40 returns and the cam claw (41;) engages again with the push lock side (741).Finally, when the fire extinguishing switch (8) is pressed, the sixth unlocking oblique side ff7 moves to the fire extinguishing slide bar (I1). ) cam claw (
4[i], the cam plate (cam plate) moves to the left by e (e>d), and the ignition slide bar (31:l) also comes off the first locking edge (64), as shown in Figure 11. Return to the original state and all the pulps (131(+41 (+51θal (+7)
