Description

  The present invention relates to a pressure cooker capable of efficiently discharging contents.

  Conventionally, like the patent document 1, the pressure cooker in which the discharge hole was provided in the side surface of the pan main body has been proposed.

JP 2013-59365 A

However, because of the need to maintain strength, in the pressure cooker, the bottom and side of the pan body are connected to each other (the lower end of the side) has a bent shape, and a discharge hole is not provided in the bent portion. It is not possible, and it is necessary to provide a discharge hole at a slightly higher position from the lower end of the side surface.
For this reason, it was difficult to take out the contents accumulated at the bottom of the pan body.

  Accordingly, an object of the present invention is to provide a pressure cooker capable of efficiently discharging contents and heating them efficiently.

  The pan body of the pressure cooker according to the present invention includes a cylindrical portion provided on the peripheral portion of the lower surface of the bottom portion so as to protrude downward, a lower surface of the bottom portion, and a portion in contact with the inner side of the cylindrical portion. A concave portion that is recessed in the direction, and at least one concave portion is provided. The bottom portion is provided with a lower discharge pipe that penetrates the side surface of the bottom portion and the upper surface of the bottom portion, and the lower discharge pipe is directed upward on the upper surface of the bottom portion. It opens and opens laterally on the side surface of the bottom portion, and an exhaust pipe that penetrates the side surface of the bottom portion and the concave portion of the bottom portion is provided at the bottom portion.

  Since the lower discharge pipe penetrates the upper surface of the bottom portion and the lower discharge hole on the side surface of the bottom portion located below the upper surface, the lower discharge pipe is efficiently stored at the bottom portion as compared with the mode in which the discharge hole is provided on the side surface of the pan body. The contents can be discharged.

  Moreover, the hot air accumulated in the space covered with the cylinder part is discharged from the exhaust hole provided in the side part of the bottom part through the concave part that guides upward and the exhaust pipe that guides sideways.

  In the process of flowing from the space covered by the cylinder part to the concave part and in the process of flowing from the concave part to the exhaust pipe, the flow path becomes narrower in stages. It takes a long time to contact the pan body, heat is easily transferred to the pan body, and it is possible to heat efficiently.

  Preferably, two or more exhaust pipes are provided in each of the one or more recesses.

  More preferably, the cross-sectional diameter of the exhaust pipe is shorter than the width and depth of the recess.

  Preferably, the bottom portion, the concave portion, and the cylindrical portion are integrally formed by casting, and the lower discharge pipe and the exhaust pipe are formed by cutting.

  In addition, by providing the concave portion, a pan body including a cylindrical portion and an exhaust pipe can be easily formed by casting and cutting.

  Preferably, the bottom and the cylinder are integrally formed by casting, and the recess, the lower discharge pipe, and the exhaust pipe are formed by cutting.

  As described above, according to the present invention, it is possible to provide a pressure cooker capable of efficiently discharging contents and heating them efficiently.

  Hereinafter, the present embodiment will be described with reference to the drawings. The pressure cooker 1 in the present embodiment includes a pan body (a container into which an object to be cooked) 10, a packing 30, and a pressure-resistant lid 50 (see FIGS. 1 to 10).

The pressure-resistant lid 50 is attached to the upper part of the pan body 10 via the packing 30.
A lid handle 51, a weight 53, and a nozzle 55 are provided above the pressure-resistant lid 50.

  A cylindrical portion 11 that protrudes downward is provided on the peripheral edge of the bottom surface of the bottom 10 a of the pot body 10.

One or more (four in this embodiment) concave portions 10b that are recessed upward are provided on the bottom surface of the bottom portion 10a and in contact with the inside of the cylindrical portion 11.
The recess 10b is formed of a column having a substantially arched bottom surface.
The concave portion 10b is provided in a portion of the bottom surface of the bottom portion 10a that is in contact with the cylindrical portion 11, but is not provided at least in a positional relationship that does not interfere with a lower discharge pipe 10d described later, that is, in a portion through which the lower discharge pipe 10d passes.

The lower discharge hole 10c and the exhaust hole 10e are provided at substantially the same height on the side surface of the bottom 10a.
Accordingly, the bottom portion 10a has a thickness such that the lower discharge pipe 10d and the exhaust pipe 10f are provided inside.

  One lower discharge hole 10c and a plurality of exhaust holes 10e are provided on the side of the bottom 10a of the pot body 10 and on the upper part of the cylinder part 11.

The lower discharge hole 10c constitutes one of end portions of a substantially L-shaped lower discharge pipe 10d that penetrates the side surface of the bottom portion 10a and the upper surface of the bottom portion 10a, and the lower discharge valve 12 is attached (FIGS. 7 and 8). reference).
That is, the lower discharge pipe 10d opens upward on the upper surface of the bottom portion 10a, and opens laterally on the side surface of the bottom portion 10a.
When the lower discharge valve 12 is opened, the contents of the pan body 10 are discharged through the lower discharge hole 10c.

The exhaust hole 10e constitutes one of the end portions of the exhaust pipe 10f that penetrates the side surface of the bottom portion 10a and the concave portion 10b of the bottom portion 10a.
Both ends of the exhaust pipe 10f open laterally.

The recess 10a and the exhaust pipe 10f form a heat induction path, and when the pan body 10 is placed on the combustor 70, hot air from the combustor 70 is exhausted through the recess 10a and the exhaust pipe 10f. 10e is discharged.
One recess 10a is provided with two or more exhaust pipes 10f.
The cross-sectional diameter d of the exhaust pipe 10f is shorter (d <w, d <h, FIG. 2, FIG. 2) than the width of the recess 10 a (substantially arch-shaped width w of the bottom surface) and depth (column height h). 9).

  An upper discharge hole 10 g and a main body handle 15 are provided on the upper portion of the pan body 10.

  An upper discharge valve 14 is attached to the upper discharge hole 10g, and when the upper discharge valve 14 is opened, the contents of the pan body 10 are discharged through the upper discharge hole 10g.

  The pan body 10 and the cylinder portion 11 are integrally formed by casting or the like, and the concave portion 10b, the lower discharge pipe 10d, and the exhaust pipe 10f are formed by cutting.

  An upper discharge pipe (not shown) penetrating the upper discharge hole 10g and the inside of the pan body 10 is also formed by cutting.

  In addition, the form formed integrally with the cylinder part 11 by casting may be sufficient as the recessed part 10b.

  In the present embodiment, the lower discharge pipe 10d penetrates the upper surface of the bottom portion 10a and the lower discharge hole 10c on the side surface of the bottom portion 10a located below the upper surface, so that a discharge hole is provided on the side surface of the pan body 10. Compared to the form, the contents stored in the bottom portion 10a can be efficiently discharged.

  Moreover, the hot air accumulated in the space covered with the cylinder part 11 is discharged from the exhaust hole 10e provided in the side part of the bottom part 10a through the concave part 10b that guides upward and the exhaust pipe 10f that guides to the side. Is done.

  In the process of flowing from the space covered by the cylinder part 11 to the recess 10b and the process of flowing from the recess 10b to the exhaust pipe 10f, the flow path becomes narrower in stages, so the cylinder part 11, the recess 10b, and the exhaust pipe 10f are provided. Compared to the form without the hot air, it takes a long time for hot air to come into contact with the pan body 10, heat is easily transmitted to the pan body 10, and it is possible to heat efficiently.

  Further, by providing the concave portion 10b, the pan body 10 including the cylindrical portion 11 and the exhaust pipe 10f can be easily formed by casting and cutting.
