[0002]
[Prior art]
FIG. 5 is an exploded perspective view of a stove burner arranged in a casing (not shown) of a conventional gas stove.
The burner body (2) is attached to the cylindrical head (12) bent up from the downstream end of the venturi (1) that mixes fuel gas and primary air with the mounting screws (20) (20). The burner body (A) is constituted by the venturi (1) and the burner body (2).
[0003]
At the center of the upper surface of the burner body (2), a cylindrical burner head mounting cylinder (21) is raised, and on the burner head tooth mounting surface (24) at the upper end of the burner head mounting cylinder (21). The burner head (3) is placed on the tooth (31) portion.
[0004]
Further, on the lower surface of the burner head (3) attached to the burner body (2), there is a central cylinder (33), outer flame hole forming teeth (31) (31), and ignition and flame monitoring. Auxiliary teeth (32), (32) for forming a flame hole and a discharge target (34) corresponding to an ignition electrode (I) described later are provided.
[0005]
Also, on the burner head tooth mounting surface (24) of the burner body (2), the insertion notch (29) for inserting the flame detector (TC) and ignition electrode (I) attached to the venturi (1) Penetrates up and down.

[Problems to be solved by the invention]
However, in the above conventional one, since one end of the plug holder (61) (62) is open, the flame detector (TC) or ignition electrode (I) sandwiched by the curved sandwiching portions (66) (66) On the other hand, when an external force acts on the open part side, they escape from the curved clamping parts (66) and (66), and the ignition electrode (I) faces the discharge target (34) on the lower surface of the burner head (3). At the same time, the flame detector (TC) does not face the flame hole for monitoring the flame (where the auxiliary teeth (32) and (32) are disposed), thereby causing a reduction in the accuracy of ignition and flame monitoring. As described above, the conventional device has a problem that the flame detector (TC) and the ignition electrode (I) are unstable with respect to external force.
[0010]
Further, since the plug holders 61 and 62 are required separately for the flame detector TC and the ignition electrode I, there is a problem that the number of parts increases accordingly.
[0011]
The present invention has been made in view of such points.
In `` Structure in which the rod-shaped flame detector (TC) and ignition electrode (I) are fixed vertically on the stop plate '', the stability of the flame detector (TC) and ignition electrode (I) is fixed. It is an object to improve and to reduce the number of necessary parts.
[0012]
[Means for Solving the Problems]
[1]
The technical means of the present invention for solving the above problems are as follows:
“The stop plate includes a central standing plate and a first bent plate and a second bent plate that are bent in opposite directions from each other from both ends in the horizontal direction of the central standing plate,
Both ends in the longitudinal direction of the spring member penetrating through the spring insertion opening provided in the central upright plate on the front and back are respectively connected to the first and second engaging portions provided on the first and second bent plates, respectively. Detachably engaged,
The flame detector (TC) and the ignition electrode (I) are clamped and held separately by the inner surface of each corner portion and the spring member at the boundary between each of the first and second bent plates and the central upright plate. That is.
According to the above technical means, the rod-shaped flame detector (TC) and the ignition electrode (I), which are mounted in an up-and-down posture, are provided at each corner of the boundary between the first bent plate and the second bent plate and the central upright plate. It is clamped and held by the inner surface of the part and the spring member. Accordingly, one of the flame detector (TC) and the ignition electrode (I) is sandwiched between the first bent plate, the central upright plate, and the spring member in a manner along the ridge line of the corner portion. As a result, there is no equivalent of the open portion at one end of the conventional plug holder (61) (62) described above (the portion that causes the ignition electrode (I) or the like to drop off). Further, the other flame detector (TC) or ignition electrode (I) is clamped by the three members of the second bent plate, the central upright plate, and the spring member. Therefore, the fixed state is more stable than when the flame detector (TC) or the like is sandwiched between the flat plate and the spring member.
[0013]
In addition, since the two parts of the flame detector (TC) and the ignition electrode (I) are fixed by a single spring member, a plug holder (to each of the flame detector (TC) and the ignition electrode (I) is attached. 61) The required number of parts is reduced compared to the conventional ones that required (62) separately.
[0014]
[2]
In the above item 1,
“The spring insertion opening is open to the upper side or the lower side of the central upright plate,
The first engaging portion is a through hole formed in the first bent plate to insert one end of the spring member so as to be freely inserted and removed,
The second engagement portion is composed of a horizontal slit portion that opens to the horizontal tip of the second bent plate, and a spring engagement slit portion that bends upward or downward from the back end portion of the horizontal slit portion. Can be assembled as follows, flame detector (TC) or ignition electrode (I).
[0015]
First, in a state where the flame detector (TC) or the ignition electrode (I) is in contact with the inner surface of the corner at the boundary between the first bent plate and the central upright plate, one end of the spring member is inserted into the through hole of the first bent plate. Insert.
[0016]
Next, the center part in the longitudinal direction of the spring member is inserted from the open part of the upper end or the lower end of the spring insertion opening that opens to the upper side or the lower side of the central upright plate.
[0017]
Thereafter, the remaining ignition electrode (I) or flame detector (TC) is brought into contact with the corner portion at the boundary between the second bent plate and the central upright plate, and in this state, the other end of the spring member is connected to the second bent plate. When moving to the back side along the horizontal slit portion opened to the tip of the spring, and further moving up and down along the spring engagement slit portion from the back end portion, the other end of the spring member becomes the second bent plate Engagement is held. As a result, the flame detector (TC) and the ignition electrode (I) are sandwiched separately by the inner surface of each corner portion and the spring member at the boundary between each of the first bent plate and the second bent plate and the central upright plate. The pressure is maintained.
[0018]
[3]
In the above item 1,
“The spring insertion opening is open to the upper side or the lower side of the central upright plate,
The first engaging portion is formed in the first bent plate and is opened in the same direction as the opening direction of the spring insertion opening, and is extended in the lateral direction from the back end portion of the upper and lower slit portions. Spring engaging slit part,
The second engaging portion is formed in the second bent plate and is opened in the same direction as the opening direction of the spring insertion port, and is extended in the lateral direction from the back end portion of the upper and lower slit portions. And a spring engaging slit portion ”.
In this structure, the spring insertion port formed in the central upright plate and the upper and lower slit portions formed in the first and second bent plates are open in the same direction (upper side or lower side). Therefore, with the flame detector (TC) and ignition electrode (I) in contact with the inner surface of each corner at the boundary between the central upright plate and the first and second bent plates, the spring insertion port and the upper and lower slits The center portion of the spring member and the vicinity of both ends can be pushed into the portion so as to slide in the vertical direction. Then, when the vicinity of both ends of the spring member reaches the spring engagement slit portion extending in the lateral direction from the back end portion of the upper and lower slits formed in the first and second bent plates, the spring member is restored. It tries to return to the initial shape by force, and thereby engages in the spring engagement slit portion. Thereby, the flame detector (TC) and the ignition electrode (I) are fixed to the stopper plate by the spring member.
[0019]
[Section 4]
In the above items 1 to 3,
In the case of “the spring member is a linear spring whose one end is folded back to be a knob part”, the linear spring can be handled by picking the knob part, and therefore a simple linear spring having no knob part. Compared to, it is easy to handle.
[0020]
[5]
In the above items 1 to 3,
In the case of “the spring member is a U-shaped spring in which one end of two parallel straight portions are connected”, the flame detector (TC) and the ignition electrode (I) are connected to the stop plate side by the two straight portions. Can be pressed. Therefore, the flame detector (TC) and the ignition electrode (I) can be fixed more stably than in the case of a single linear spring.
[0021]
[Section 6]
In the above items 1 to 3,
In the case where “the spring member is a long strip-shaped leaf spring on one side”, the spring member is the outer peripheral surface of the flame detector (TC) or the ignition electrode (I) as compared to the case where a linear spring is adopted as the spring member. Contact over a wide range. Therefore, the stability of the flame detector (TC) and the ignition electrode (I) is further improved as compared with the case where a linear spring is employed.
[0022]
【The invention's effect】
The present invention has the following specific effects.
Since the flame detector (TC) and the ignition electrode (I) are clamped and held between the first bent plate or the second bent plate, the central upright plate, and the spring member, the conventional plug holder (61 ) (62) no longer corresponds to the open part at one end (the part that causes the ignition electrode (I) etc. to drop off), and the mounting posture of the ignition electrode (I) etc. is stabilized.
[0023]
Further, since the rod-shaped flame detector (TC) and the ignition electrode (I) are pressed by the spring member against the corner portion in a mode along the ridgeline of the corner portion, as described above, the flat portion Compared with the case where a structure in which a spring member is pressed is used, the mounting posture is stabilized.
[0024]
Since the two parts of the flame detector (TC) and the ignition electrode (I) are fixed by a single spring member, the plug holder (61) is attached to each of the flame detector (TC) and the ignition electrode (I). The number of necessary parts is reduced compared to the conventional one described above, where (62) was required separately.
[0025]
In the item of item 2, since the spring insertion opening opens to the upper side or the lower side of the central upright plate, the spring member can be inserted into the spring insertion opening via the opening. Also, one end of the spring member is pushed so as to slide into the horizontal slit from the open end of the horizontal slit that constitutes the second engaging portion that opens to the front end of the second bent plate. It can be made to engage with the spring engagement slit part continuing to the end part. Therefore, as compared with the case where a simple through hole is employed as the spring insertion port or the second engagement portion, the attachment work of the spring member can be performed smoothly.
[0026]
In the item of item 3, the spring member can be pushed so as to slide entirely from the vertical direction into the spring insertion opening and the vertical slit formed in the central upright plate and the first and second bent plates. The mounting operation of the spring member can be performed more smoothly.
[0027]
In the item of item 4, since the knob portion can be picked, handling becomes easier as compared with a simple linear spring.
[0028]
In the case of item 5, since a U-shaped spring having two parallel straight portions is adopted as a spring member, a flame detector (TC) and an ignition electrode ( I) can be fixed more stably.
[0029]
In the case of item 6, since a strip-shaped plate spring is adopted as a spring member, as in the case of item 5, the flame detector (TC) and the ignition electrode (I) are compared with the case of a single linear spring. The mounting posture of the is more stable.
