生じ、吹鳴しないことがある。“Problems that the invention attempts to solve” Lid 104 and main body 10 of the above-mentioned seedling water heater
1, the convex portion 107 of the cylindrical wall 106 of the lid 104 abuts against the opening wall 103 of the main body 101 and is bent inward using the base of the cylindrical wall 106 as a fulcrum, and as a reaction force, the main body 101 opening wall 10
3, the lid 104 cannot be pushed up by the increased steam pressure that causes the lid to blow, but it is pushed up only when it receives abnormal internal pressure when a bumping phenomenon occurs. It is possible to provide a fitting mechanism having a fitting holding force such as that shown in FIG. However, when fitting the lid 104 into the opening 102, a plurality of convex portions 107 formed on the outer peripheral surface of the cylindrical wall 106
Since the lid 104 is always in contact with the opening wall 103 of the main body 101 and is elastically deformed, a considerable amount of force is required to open and close the lid 104, which is especially a problem for housewives who use the water heater. That is, since it takes force to close the lid 104, it must be closed to the completely sealed state shown in FIG. 4, but the lid wall 1 shown in FIG.
05 does not come into contact with the upper part of the opening wall 103
7 engages in the middle of the opening wall 103, resulting in an incompletely closed state. Also, when closing the lid 104, the opening wall 1
03 and the cylindrical wall 106, spring back acts to create a gap, resulting in an incompletely closed state. In such an incompletely closed state, steam may leak and the blower may not blow.

外方に突設したものである。``Means that the invention attempts to solve'' Therefore, the present invention aims to solve this problem by devising that the lid cannot be pushed up by the steam pressure raised to the point where it blows the lid, but only when the lid is exposed to abnormal internal pressure when a bumping phenomenon occurs. In addition to providing a fitting mechanism that has a fitting retention force that allows the lid to be pushed up, the lid can be opened and closed easily.
Furthermore, the present invention provides a seedling-blowing water heater whose lid can be securely closed and which does not leak steam, in which the periphery of the upper opening of the main body is formed into an arc-shaped curling wall, and the fitting portion of the lid is in contact with the upper part of the curling wall. A cylindrical wall that loosely fits into the opening of the main body is formed below the sloping wall, and a protrusion that clamps the curling wall between the cylindrical wall and the slanted wall is spaced apart in the circumferential direction and is placed on the outside. It is a projecting structure.

壁８に形成する。カーリング壁８は、その断面が
円弧状に形成してあるため、開口７部分は上下の
位置で円筒壁のように同一内径でなくその内径が
変化するものである。 The periphery of the upper opening 7 of the main body 1 is formed into an arcuate curling wall 8. Since the curling wall 8 has an arcuate cross section, the inner diameter of the opening 7 portion changes at the upper and lower positions, instead of being the same as in a cylindrical wall.

本体１最上面からの位置をH1とすると、
Ｈ＞H1
なる関係がある。 Here, the minimum inner diameter of the opening 7 of the main body 1 is D 1 ,
When the outer diameter of the cylindrical wall 10 of the lid 5 is D 2 and the protrusion height of the protrusion 11 is t, the relationship between them is (D 2 +2t)>D 1 >D 2 . When the lid 5 is closed, the protrusion 11
Let H be the distance from the top surface of the main body 1 to the maximum outer diameter part of .
カーリング壁８は断面円弧状に形成してあるた
め剛体で突起１１が衝合しても変形せず、円筒壁
１０が弾性変形して外向き傾斜壁９とカーリング
壁８を挾持するので、蓋５が確実に閉まり蒸気も
れはない。 Since the curling wall 8 is formed to have an arcuate cross section, it is a rigid body and will not deform even if the protrusions 11 collide, and the cylindrical wall 10 will elastically deform and sandwich the outwardly inclined wall 9 and the curling wall 8. 5 is securely closed and there is no steam leakage.

開け閉めが抵抗がなく容易である。"Effects of the invention" As described above, the present invention forms the opening periphery of the main body with a curling wall, and the fitting part of the lid is formed with an outwardly inclined wall and a cylindrical wall connected to the outwardly inclined wall. Since the protrusion that holds the curling wall between the slanted wall and the protrusion is provided, the lid can be easily opened and closed. Furthermore, the lid cannot be pushed up by the steam pressure raised to the point where the lid is blown, but the fitting has a fitting retention force that allows it to be pushed up only when abnormal internal pressure is applied when a bumping phenomenon occurs. functions can be easily provided. In addition, according to the present invention, since the curling wall is formed into an arcuate cross-section, it is a rigid body and does not deform even when the protrusions collide, and the cylindrical wall elastically deforms to sandwich the outwardly inclined wall and the curling wall. The lid closes securely, there is no steam leakage, and there is no noise like the conventional ones. In addition, in the present invention, when opening and closing the lid from a direction slightly oblique to the main body 1, the plurality of protrusions 11 do not contact the curling wall 8 of the main body 1 at the same time.
Since you can make them contact each other individually,
Opening and closing is easy with no resistance.
