Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a diagonal shaft stirrer for heating pots used for making bean paste, sauces, soups, and boiling down other foods.

[Conventional technology]

Conventionally, as shown in Japanese Utility Model Application Publication No. 59-138429, a stirring shaft driven by an electric motor is placed diagonally upward in a heating pot with a hemispherical bottom. An arc-shaped support rod that runs along the inner surface of the bottom of the heating pot is fixed to the tip of this stirring shaft, and a stirring blade made of a flexible material that slides into contact with the inner surface of the heating pot is attached to this support rod. is used.

In such a conventional oblique shaft stirrer, the stirring shaft is rotated by an electric motor, and the stirring blades are rotated through the support rod to stir and mix the materials to be stirred.
Solids that have settled at the bottom of the heating pot in the material to be stirred can also be scooped up and stirred.

[Problem that the invention attempts to solve]

In the above-mentioned oblique shaft stirrer, the central part of the heating pot is located far from the stirring blades, so when the stirring blades operate, the material to be stirred does not move easily, making it impossible to stir and mix thoroughly. This invention solves the above-mentioned problems and provides an oblique shaft stirrer that can improve the movement of the materials to be stirred in the center of the heating pot and promote stirring and mixing of the materials to be stirred. The purpose is to

[Means for solving problems]

In the above-mentioned oblique shaft stirrer, this device moves an auxiliary stirring member parallel or perpendicular to the stirring shaft from above to the lower part of the heating pot, avoiding rotating members such as the stirring shaft, support rod, and stirring blades. This is what was inserted.

[Effect]

This device has the above-mentioned stirring auxiliary plate, so when the material to be stirred moved by the stirring blade hits the stirring auxiliary member, the material to be stirred becomes turbulent, promoting stirring and mixing. However, the movement of the material to be stirred is improved, especially in the center of the heating pot, allowing for sufficient mixing and stirring.

[Embodiment] An embodiment of this invention will be described below with reference to FIGS. 1 to 3.

In FIGS. 1 and 2, 1 is a heating pot;
This heating pot 1 has a cylindrical portion 1b integrally formed on a hemispherical bottom portion 1a, and a steam chamber 2 is formed on the outer circumferential side of the bottom portion 1a, and steam is introduced into the steam chamber 2. It is fed and heated and used for kneading bean paste and boiling down other foods.

An electric motor 3 with a speed reducer is disposed above one side of the heating pot 1, and the electric motor 3 is fixed to a part of the outer peripheral surface of the heating pot 1 via a mounting member 4 and a support base 5. A stirring shaft 6 to which driving force is transmitted from the electric motor 3 loosely passes through a pot lid 7, which will be described later, and is inserted into the heating pot 1 from diagonally above so as to intersect with the axis of the heating pot 1.
The tip of the stirring shaft 6 is supported by a bearing 8 provided on the inner surface of the bottom 1a of the heating pot 1, and the center portion of a support rod 9 is fixed to the tip of the stirring shaft 6. The support rod 9 is formed in an arc shape with a length of a semicircle or more along the inner surface of the bottom 1a of the heating pot 1, and the stirring blades 10 protruding toward the outer circumferential side of the support rod 9 are arranged at multiple locations in the longitudinal direction of the support rod 9 ( It is attached at 5 locations in Figure 1). The stirring blades 10 are disposed asymmetrically with respect to the support rod 9, so that the entire inner surface of the bottom 1a of the heating pot 1 is rubbed by one rotation of the stirring shaft 6. Further, the stirring blades 10 are each divided into several pieces 11 at a plurality of locations so as to substantially intersect with the longitudinal direction of the support rod 9. Split piece 11
are removably attached to the support rod 9 in close contact with each other, and are made of an integrally molded product made of a heat-resistant and flexible material such as nylon plastic.

The pot lid 7 has a circular planar shape that covers the upper opening of the heating pot 1, and is composed of two semicircular members 12 and 13, and these members 12 and 13 are connected 14 on the diameter of the pot lid 7. A hole 12a through which the inclined stirring shaft 6 freely passes is formed in one member 12, and the other member 13 is connected to the one member 12 by the connecting portion 14.
The other member 13 has an input port 13a which is opened and closed by moving vertically relative to the input port 13a.
A small lid 1 is provided to open and close this inlet 13a.
6 is provided. Further, the pot lid 7 is provided with a raw material inlet 16 extending over both members 12 and 13.

An upper end of a stirring auxiliary member 17 having a hollow diamond shape in cross section is fixed to the lower part of the mounting member 4 of the electric motor 3. The stirring auxiliary member 17 loosely penetrates the hole 12a of the pot lid 7 from above and is inserted into the heating pot 1 parallel to the stirring shaft 6, while avoiding the stirring shaft 6, the support rod 9, and the stirring blade 10. It is arranged as follows. As shown in FIG. 3, the stirring auxiliary member 17 has a lower limit sensor 19 and an upper limit sensor 20 at two locations in the vertical direction for detecting the liquid level of the material to be stirred, and also has a sensor 20 at the inner bottom of the heating pot 1. A temperature sensor 18 is provided respectively.

In the oblique shaft stirrer of the embodiment configured as described above, the stirring blades 10 are rotated integrally with the stirring shaft 6 and the support rod 9 by the drive of the electric motor 3, and the tips of these divided pieces 11 are slightly bent. It is bent and slides into contact with the inner surface of the bottom portion 1a of the heating pot 1 to scrape off the material to be stirred from the inner surface and stir and mix it. In this case, the stirring blade 10 scoops up and stirs the solid matter in the material to be stirred that has sunk to the bottom 1a of the heating pot 1, and the stirring auxiliary member 17 acts as a baffle plate, and when the material to be stirred hits, the solid matter is stirred. The movement of the material to be stirred is disturbed, promoting stirring and mixing, and the movement of the material to be stirred, especially in the center of the heating pot, is improved, and the stirring and mixing effects can be enhanced.

In addition, in this embodiment, since the temperature sensor 18 is provided on the stirring auxiliary member 17, the temperature of the object to be stirred in the heating pot 1 can be directly measured by these sensors, and the cooking temperature, the intensity of heating, etc. can be controlled. Since the temperature of the stirred material is directly measured, accurate control is possible. Moreover, the lower limit and upper limit sensors 19 and 20 allow accurate control of the liquid level of the object to be stirred.

In this invention, as illustrated in FIGS. 4 to 6, the stirring auxiliary member is designed to
The area and shape can be changed, and the stirring auxiliary member can be provided with a liquid level sensor and a temperature sensor for the object to be stirred. In addition, the stirring auxiliary member may be inserted vertically from above to the lower part of the heating pot, but in this case, it must be avoided so as not to hit rotating members such as the stirring shaft, support rod, and stirring blade. is necessary. Furthermore, a stirring boss may be provided on the inner peripheral side of the support rod.

[Effect of idea]

As explained above, according to this invention, the stirring auxiliary member that is parallel or perpendicular to the inclined stirring shaft is
By using the space that does not get in the way of the rotating member provided in the heating pot and installing it inside the heating pot, stirring and mixing of the materials to be stirred can be promoted, and sufficient stirring can be achieved even in the center of the heating pot. This has the effect of providing an oblique shaft agitator that can perform mixing.
