Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating pot for performing boiling processing while stirring and pulverizing food, and more particularly to a discharge valve structure of a discharge pipe for discharging the boiled stirring contents.

[0002]

2. Description of the Related Art Conventionally, a so-called spherical valve as shown in FIG. 3 has been generally used as a discharge valve for agitated contents having poor fluidity. This spherical valve has been widely used because it can be completely closed irrespective of fluidity when closed and has no leakage.

[0003]

However, in the state of FIG. 3, the above-mentioned spherical valve slides in close contact with the spherical portion inside the valve seat 21 (consisting of upper and lower valve seats having a hemispherical recess). However, when the valve body 22 is rotated by 90 ° to be in the closed state, the space 21a in the upper valve seat portion of the valve body 22 remains as it is. In a general case, this space 21a is not a problem, but in the case of a heated food pot having a stirrer and a crushing cutter of the present invention, this space 21a is not a problem.
The solid matter that has entered the inside 1a is not pulverized by stirring, but is discharged as it is when the spherical valve is opened. Therefore,
If such a discharge valve is used, contents which are not uniform and are not uniformly stirred and crushed will be mixed in, though only a small part.

[0004] It is an object of the present invention to solve the above-mentioned problems and to provide a discharge valve capable of completely and uniformly stirring and pulverizing the contents.

[0005]

In order to solve the above-mentioned problems, the upper half is formed by a cylindrical portion 1a, and the lower half is formed by the bottom of a hemispherical portion 1b connected to the cylindrical portion 1a. The upper lid 2 of the heating pot 1 extends from the hemispherical portion 1b to the bearing side of the oblique shaft that penetrates the outer periphery thereof, that is, from the position near the periphery of the cylindrical portion 1a to the bearing 3 provided at the bottom of the hemispherical portion 1b. An oblique shaft type stirrer in which a plurality of stirring blades 8 are distributed and arranged outside the support rod 7 so as to be in contact with the hemispherical portion 1b; ,
A cutter rotating coaxially with the stirrer is provided,
b, the discharge valve at the upper end of the discharge pipe 9 has a valve seat 11 having the same spherical upper surface as the inner surface of the hemispherical portion 1b, and a cylindrical shape of the valve seat 11. And a valve body 10 having an upper surface which is inserted into the discharge port 11a and has the same spherical surface as the inner surface of the hemispherical portion 1b at the time of insertion.
The valve element 10 includes a cylindrical insertion portion 10a, an annular packing 10c inserted below the column, and a column 10b for moving the valve element 10 up and down. Is closed, and is lowered when opened to open the discharge port 11a.

[0006]

FIG. 1 is a cross-sectional view of a discharge pipe provided with a valve according to the present invention, and FIG. 2 is a cross-sectional view of a food heating kettle provided with the discharge pipe of FIG. The food heating pot is a heating pot 1 having an upper portion formed of a cylindrical portion 1a and a lower portion formed of a bottom portion of a hemispherical portion 1b connected to the cylindrical portion 1a. 1c is provided. The upper end of the cylindrical portion 1a is closed by a lid 2, and an oblique axis that is obliquely obliquely penetrates from the outer periphery of the lid 2, that is, a position near the periphery of the cylindrical portion 1a, and is provided immediately below the lid 2. Rotating separator 4
And the cutter shaft 5 along the rotation center line and the cutter shaft 5
Are separated into two parallel stirring shafts 6 which are integrated at a predetermined distance from each other on both sides.

The above-mentioned oblique axis is the heating pot 1 up to the rotary separator 4.
And a coaxial structure driven by a high-speed rotating cutter motor and a low-speed rotating stirring motor fixed to be positioned on the center side of the lid 2 and rotating in opposite directions.

At the lower end of the stirring shaft 6, a supporting rod 7, which is held by the bearing 3 and is separated from the hemispherical portion 1 b of the heating pot 1 by a predetermined distance so as to rotate by the stirring shaft 6, sandwiches the bearing 3. Fixed on both sides. The supporting rod 7 has a hemispherical portion 1b.
The stirring blades 8 configured to be in contact with the inner surface at a constant pressure are dispersedly arranged.

At the lower end of the cutter shaft 5 on the rotation center line, a disk-shaped cutter 12 is mounted.
In addition, it is configured to rotate at high speed in a direction opposite to the rotation direction of the stirring blade 8.

A discharge pipe 9 is provided at the lower end of the heating pot 1 (the lower end of the hemispherical portion 1b) in order to discharge the contents boiled down while being pulverized in the heating pot 1. The discharge pipe 9 is connected to a valve seat 11 fixed (welded) to the lower end of the hemispherical portion 1b and is bent at about 90 °.

The valve seat 11 is polished so that the upper surface thereof becomes a spherical surface which coincides with the inner surface of the hemispherical portion 1b, and is welded to the hemispherical portion 1b.
It is fixed to. The outlet 11a of the valve seat 11 has a cylindrical surface, and the lower side has a conical surface.

The valve body 10 corresponding to the valve seat 11 has a cylindrical portion 10a which is loosely fitted into the discharge port 11a, and a cylindrical portion 10a.
And a packing 10c having an inclined surface on the outside so as to be in close contact with the conical surface of the discharge port 11a by an elastic body such as an annular rubber fitted to the lower side of the cylindrical portion 10a. Is polished so as to have the same spherical surface as the hemispherical portion 1b, and is configured to form an integral spherical surface when closed. The valve element 10 is supported by a column 10b that moves the valve element 10 up and down.
Slides through the curved discharge pipe 9 and external lever 1
3 is held. The lever 13 has a spring 14
And the discharge port 11a is normally closed by the valve body 10, but by pulling down the lever 13 against the spring 14, the valve body 10 also moves downward and the discharge port 11a Is released.

In the above-described embodiment, the food heating and pulverizing pot of the oblique shaft type stirrer has been described. However, the present invention is not necessarily limited to such a container, and it is needless to say that the present invention can be used for containers of any shape.

[0014]

As described above, the discharge port 11a is provided by the valve body 10.
When the is closed, the hemispherical portion 1b, the valve seat 11, and the valve body 10 are completely integrated spherical surfaces, so that the pulverization by the stirrer or the cutter 12 can be completely performed, and the concave portion 21a of the spherical valve as in the related art is formed. The content that has entered does not remain without being crushed and stirred.

Since the discharge pipe 9 and the discharge valve can be easily disassembled except for the valve seat 11, the disassembly and cleaning are extremely easy.
