The injection valve is configured such that the opening degree increases as the separation distance between the grip portion 84 and the injection lever 86 decreases.

The shower body 81 configured in this manner is configured to be held by the shower holder 50 attached to the side panel 11 a of the housing 11 . As will be described later, the shower holder 50 is configured to hold the nozzle portion 82 and the grip portion 84, and also to hold an intermediate portion 85 closer to the nozzle portion 82 than the grip portion 84 or closer to the connection portion 83 than the grip portion 84. It is

The valve bracket 60 is attached to the bottom panel 11b of the housing 11 by mainly sandwiching the water supply valve 45 between the bracket base 61 and the bracket cover 71 . In this embodiment, for example, the bracket base 61 and the bracket cover 71 are formed by sheet metal processing a stainless steel plate having a thickness of 1 mm.

As shown in FIG. 9( a ), the bracket base 61 has a horizontally long rectangular base plate 62 that can be screwed to the bottom panel 11 b of the housing 11 . 66 and a second retaining wall 67 . The base plate 62 is formed with two through holes 62a through which bolts can be inserted to fix the base plate 62 to the bottom panel 11b by screwing to the bottom panel 11b.

When the base plate 62 is attached to the bottom panel 11b, the left side of the base plate 62 is formed with a flange portion 63 bent downward at right angles. Female screw holes 63 a are formed in the flange portion 63 at two locations in the front-rear direction of the base plate 62 . Similarly, a first holding wall 64 is formed on the rear side of the base plate 62 by bending downward at a right angle, and a clamping plate 66 is formed on the right side of the first holding wall 64 and is bent rearward at a right angle. . On the other hand, a second holding wall 67 is formed by bending downward on the front side of the base plate 62 .

The bracket cover 71 includes a flange portion 76 and a stopper portion 78 centered on a cover plate 72 having a plate shape elongated in the front-rear direction by rotating the katakana "ko" counterclockwise by 90 degrees. The cover plate 72 is formed with two through holes 74 through which bolts 79 can be inserted which are screwed into the female screw holes 63a of the base plate 62 to fasten the two.

When the cover plate 72 is attached to the bottom panel 11b, a handle insertion hole 73 is formed on the rear side of the cover plate 72 so that the handle 45c of the water supply valve 45 can be inserted. A flange portion 76 is formed which is bent inward. Similarly, a stopper portion 78 is formed on the lower front side of the cover plate 72 so as to be bent rightward at a predetermined angle.

The predetermined angle of the stopper portion 78 is set to the inclination angle of the outer surface of the screw head of the union nut 91 when the screw is tightened. For example, when the screw head of the union nut 91 has six outer surfaces (the axial shape of the screw head is a regular hexagon), the predetermined angle is set to 120 degrees. Further, when the screw head has eight outer surfaces (the axial shape of the screw head is a regular octagon), the predetermined angle is set to 135 degrees.

The first holding wall 64 is provided with a U-shaped groove 65 that opens to the left and is formed in the left-right direction. The water supply valve 45 is locked in this U-shaped groove 65 . The second holding wall 67 is also provided with a V-shaped groove 68 that opens to the left and is formed in the left-right direction. A portion of the shower hose 90 near the union nut 91 is locked in the V-shaped groove 68 .

In FIG. 9, the bracket base 61 is shown removed from the bottom panel 11b of the housing 11, but in the actual machine, the bracket cover 71 is assembled with the bracket base 61 attached to the bottom panel 11b. .

That is, first, the input end 45a of the water supply valve 45 is connected to a water supply pipe (not shown) provided in a kitchen or the like where the heating cooker 10 is installed, and then, as shown in FIG. 2, the output end 45b of the water supply valve 45 is connected to the input end 47a of the pressure reducing valve 47, and the union nut 91 of the shower hose 90 is connected to the output end 47b of the pressure reducing valve 47. After removing the handle 45c from the water supply valve 45, the handle 45c is passed through the handle insertion hole 73 of the bracket cover 71 and attached to the water supply valve 45 again. Thereby, the water supply valve 45 is attached to the bracket cover 71 (see FIG. 9B).

Then, the water supply valve 45 already attached to the bracket cover 71 is accommodated in the U-shaped groove 65 so as to be sandwiched between the clamping plates 66 for the bracket base 61 attached to the bottom panel 11b. A portion near the nut 91 is accommodated in the V-shaped groove 68 (see FIG. 9(c)). After that, the bracket base 61 and the bracket cover 71 are screwed together with the bolts 79 so that the water supply valve 45, the decompression valve 47 and the union nut 91 are sandwiched between the bracket base 61 and the bracket cover 71, and the bottom panel 11b is mounted on the bottom panel 11b. can be attached to

By attaching the water supply valve 45 and the like to the valve bracket 60 by such an assembly process, the water supply valve 45, pressure reducing valve 47, shower The hose 90, the bracket cover 71, and the bracket base 61 can now be assembled in this order.

Also, since what is held between the bracket base 61 and the bracket cover 71 is the water supply valve 45 and the union nut 91 of the shower hose 90, when assembling the water supply valve 45 etc. to the local water supply pipe (not shown), In addition, excessive force is less likely to be applied to the pressure reducing valve 47 . As a result, the valve housing and the like of the pressure reducing valve 47 can be changed from metal to resin.

Further, in a state in which the water supply valve 45, the pressure reducing valve 47 and the union nut 91 are sandwiched by the valve bracket 60 composed of the bracket base 61 and the bracket cover 71, the flange portion 76 of the bracket cover 71 does not act as the water supply valve. 45, and the stopper portion 78 abuts on the outer side surface of the screw head of the union nut 91 in a substantially flat state. As a result, the union nut 91 is pressed by the stopper portion 78 so that it cannot rotate. Rotation of the union nut 91 is prevented. Therefore, loosening of the union nut 91 in such a case can be prevented.

Further, the U-shaped groove 65 of the first holding wall 64 and the V-shaped groove 68 of the second holding wall 67 are both opened to the left side, and the bracket cover 71 is also opened to the bracket base 61 from the side panel 11a side. Can be attached and detached. Therefore, the bracket cover 71 having the water supply valve 45 and the like can be easily attached to and detached from the bracket base 61 from the side panel 11a side.

As shown in FIGS. 10 to 12, the shower holder 50 that holds the shower main body 81 on the side panel 11a of the housing 11 is also formed by sheet-metal processing a stainless steel plate like the valve bracket 60. As shown in FIG. The shower holder 50 is formed by processing a stainless steel plate having a thickness of 1.5 mm to 2.0 mm, for example.

In this embodiment, the shower holder 50 is composed of a holder body 51 having a shape obtained by rotating the katakana character "ko" clockwise by 180 degrees in a plan view, and flange portions 52 and 53 formed at both ends of the holder body 51. (see FIG. 10(c)). The flange portions 52 and 53 are provided for attaching and fixing the shower holder 50 to the side panel 11a, and are formed with four through holes 54 through which screw fastening bolts can be inserted.

A Y-shaped groove 55 is formed in the front wall portion 51a of the holder body 51 facing forward. In this embodiment, the Y-shaped groove 55 includes a groove opening portion 55a having a wide groove width Wa, a groove bottom portion 55b having a narrow groove width Wb, a stepped portion 58 of a groove intermediate portion 55c connecting both grooves in a tapered shape, It is composed of These groove widths Wa and Wb are determined based on the external dimensions of the shower main body 81 and the grip portion 84 .

As shown in FIG. 12B, the groove width Wa, which is the opening width of the groove opening 55a, is set slightly larger than the outer width Da of the large diameter portion 81a of the shower main body 81. As shown in FIG. A groove width Wb connected to the groove bottom portion 55b is set to be slightly larger than the outer width Db of the grip portion 84 having a cylindrical shape. By setting the groove widths Wa and Wb in this manner, the large-diameter portion 81a of the shower body 81 can be held at the groove opening 55a of the Y-shaped groove 55 of the front wall portion 51a. The groove bottom portion 55b of the groove 55 can hold the grasping portion 84. As shown in FIG.

On the other hand, a U-shaped groove 57 is formed in the rear wall portion 51b facing rearward. The U-shaped groove 57 has the same groove width Wc from the groove opening 57a to the groove bottom 57b, is larger than the outer width Dc of the small-diameter portion 81b near the nozzle portion 82 of the shower body 81, and extends outside the nozzle portion 82. It is set smaller than the width Dd. As a result, the vicinity of the nozzle portion 82 of the shower body 81 can be held in the U-shaped groove 57 of the rear wall portion 51b.

Thus, the Y-shaped groove 55 and the U-shaped groove 57 of the shower holder 50 hold the shower main body 81 of the shower device 80 at three points (the large diameter portion 81a, the small diameter portion 81b, and the grip portion 84). As a result, the grip portion 84 and the large-diameter portion 81a are also held by the shower holder 50, compared to the case where only the nozzle portion 82 of the shower main body 81 is held by the shower holder 50, for example. Therefore, the shower body 81 held by the shower holder 50 is prevented from rattling in the left-right direction and from rotating around the nozzle part 82, so that the shower body 81 of the shower device 80 can be stably attached to the shower holder 50. I was able to keep it.

11(a), the shower holder 50 is Y-shaped so as to be able to hold the shower body 81 substantially horizontally with respect to the mounting surface of the heating cooker 10. As shown in FIG. The groove depths of the groove 55 and the U-shaped groove 57 are set. This made it possible to hold the shower main body 81 more stably.

Furthermore, as shown in FIG. 11B, a gap S corresponding to the thickness of the shower hose 90 is formed between the shower main body 81 held by the shower holder 50 and the side panel 11a. A shower holder 50 is constructed. As a result, for example, even if part of the shower main body 81 protrudes upward from the uppermost part of the shower holder 50, that is, the uppermost part 59, the shower hose 90 wound around the gap S can now be hung.

In this embodiment, as shown in FIG. 12(a), when the shower holder 50 holds the shower body 81, the top 59 of the shower holder 50 and the top 89 of the shower body 81 are at substantially the same height. The groove depths of the Y-shaped groove 55 and the U-shaped groove 57 are set so that Therefore, for example, even when the shower holder 50 holds the shower main body 81, the shower main body 81 does not protrude beyond the uppermost portion 59 of the shower holder 50 as indicated by the dashed line K. Thereby, an object can be placed on the shower holder 50 even when the shower main body 81 is held. For example, the excess length of the shower hose 90 wound two or three times can be hung or placed on the shower holder 50 .

In the heating cooker 10 configured as described above, the water supply valve 45 is connected to the wash water supply pipe to open and close the water supply pipe, and the output end 45b of the water supply valve 45 is connected to reduce the pressure of the wash water. Equipped with a valve 47, a shower hose 90 having one end 90a connected to an output end 47b of the decompression valve 47 via a union nut 91, and a shower body 81 connected to the other end 90b of the shower hose 90. .
