Description

[Detailed Description of the Invention] This invention relates to a steam-heated boiling pot device, and particularly relates to an improvement of a boiling pot device that can uniformly heat the pot body by steam.

Steam-heated boiling pots generally have a double-walled pot body, which allows steam to flow into the jacket to heat the pot and boil, stir-fry, etc. Compared to those using propane gas, city gas, etc. as a heating heat source, there is no need for ventilation, heat shielding, etc., making heat management easier.

However, the problem with this type of boiling pot is whether the steam supplied inside the jacket can be dispersed so as to uniformly heat the pot body.

Especially when heat-treating stir-fried foods such as fried noodles and fried rice,
This is because if the supply and distribution of steam to the pot body within the jacket is not uniform, local overheating will occur in the pot body, causing the food to burn.

Therefore, in the past, the jacket of the boiling pot is equipped with a baffle plate or fins for uniformly distributing steam from the spout to the entire heated part of the pot body, or has a large number of steam spouts. A method in which multiple steam introduction pipes are arranged inside a jacket has been proposed and is in use in some cases, but in either case, it is necessary to form a rectifier plate or fins inside the jacket, or to arrange the steam introduction pipes. The installation is troublesome and the structure is complicated, and the volume of the jacket becomes large.
This also has the disadvantage of increasing the size of the pot body.

This idea was made to solve the above-mentioned conventional problems, and its purpose was to inject steam into the jacket from a single steam outlet to cover the entire heated part of the pot body. To provide a steam heating type boiling pot device capable of uniformly heating food.

For this reason, in the steam-type boiling pot device of the present invention, the boiler body with a double structure and a steam jacket is supported horizontally rotatably, and the axis line is set at the center of the bottom of the outer shell constituting the jacket. A steam introduction pipe aligned with the rotational axis of the pot body is mounted so as to be relatively rotatable by a rotary joint mechanism, and a plurality of jets for ejecting steam in a radial direction are installed at the tip of the steam introduction pipe protruding into the jacket. By shaping the outlet and rotating the pot body, the steam ejected from the spout can be uniformly dispersed over the entire area of the heated portion of the pot body.

Hereinafter, embodiments of this invention will be described with reference to the drawings.

FIG. 1 shows an example of a steam-type boiling pot device according to this invention, and 1 is a circular pot body, and the pot body 1 has an outer shell 2 with a space between its outer peripheral surfaces on the bottom side. As a result, it has a double structure, whereby the inner space of the outer shell 2 is used as a steam jacket 3.

In addition, a hole 4 is bored in the center of the bottom of the outer shell 2, and this hole 4
The upper end of the steam introduction pipe 5 is inserted into the interior, and
The steam introduction pipe 5 is relatively rotatably attached to the outer shell 2 by a rotary joint mechanism 6 whose axis coincides with the central axis (rotation axis) of the pot body 1.

As shown in FIG. 2, the rotary joint mechanism 6 includes a flange 8 fixed to the lower surface of the bottom of the outer shell 2 by a bolt 7 concentrically with the hole 4, a bush 9 concentrically attached to the center of the lower surface of the flange 8, and the bush 9. A holder 10 is rotatably fitted on the outer periphery of the bushing 9 and closes the lower end opening of the bushing 9. A seal ring 12 is fitted inside, and one end surface of this seal ring 12 is pressed against a seat surface 13 formed on the holder 10 by a compression spring 14 disposed inside the bushing 9, thereby fitting the bushing 9 and the holder 10. Furthermore, the steam introduction pipe 5 is arranged on the central axis of the bush 9, and its lower end is fixed to the holder 10.
It communicates with a steam supply port 15 provided in the.

Further, the opening at the tip of the steam introduction pipe 5 inserted into the jacket 3 is closed by a plate member 16, and a plurality of spout ports 17 are formed on the outer periphery of the pipe for spouting steam in the radial direction. A plate member 31 that is located at , guides the steam ejected from the spout 17 toward the distal end of the jacket 3 , and suppresses direct outflow of steam to the drain port 18 .
is attached to the inner wall of the outer shell 3.

Further, a support ring 19 that horizontally supports the hook body is integrally attached to the upper outer periphery of the outer shell 2 of the hook body 1 configured as described above, and this support ring 19 is attached to the inner surface of the support frame 20. Multiple units installed in the same horizontal position ((
In the embodiment, the support ring 19 is mounted horizontally rotatably on three guide rollers 21 and one drive roller 22, and on the upper surface of the support ring 19 there is a roller mounted on the support frame 20.
More than one holding roller 23 is engaged.

One of the right and left ends of the support frame 20 is attached to a column 25 erected on the base 24, and the other is attached to the side surface of a control box 26 installed on the base 24.

Note that if the pot body 1 is made tiltable in order to facilitate the removal of heat-treated food, etc.
6 may be connected via the rotation axis.

A drive device 27 is installed in the control box 26, and this drive device 27 rotates the drive roller 22 for horizontal rotation of the pot body 1 and also drives a food stirrer 28, which will be described later.

The food stirrer 28 is attached to the tip of an arm 29 that protrudes horizontally from the control box 26 in the direction of the pot body 1, and the arm 29 is moved up and down by a drive device 27 and reciprocated at a desired angle, allowing manual sliding. It is designed to stir food in the same way as the operation.

Next, the operation of the boiling pot device according to the invention constructed as described above will be explained.

For example, when cooking stir-fried food such as fried rice, steam is first supplied from a steam source (not shown) to the steam introduction pipe 5 through a pipe 30 connected to the supply port 15 of the holder 10 of the rotary joint mechanism 6.

Then, the boiler body 1 ejected into the jacket 3 from the upper end ejection port 17 of the steam introduction pipe 5 is heated.

Further, drain generated by condensation of steam within the jacket 3 is discharged to the outside of the pot body 1 through the hole 4, the bush 9, and the drain port 18.

As a result, the stir-fried food is put into the pot body 1 in a state where the pot body 1 is sufficiently heated, the drive device 26 is started, the pot body 1 is horizontally rotated by the drive roller 22, and at the same time the arm 2
When the stirrer 9 is moved up and down and rotated back and forth, the stirring wheel 28 moves in a circular or elliptical direction from the edge of the pot toward the center while slidingly contacting the inner wall surface of the pot, similar to when operating a paddle manually, and moves in a circular or elliptical direction toward the center of the pot body 1.
The stir-fried food inside the pot is stirred, and as the pot body 1 is rotated horizontally, the above-mentioned stirring operation is performed evenly from 360 degrees of the pot body.

On the other hand, when the pot body 1 is horizontally rotated with the rotation of the drive roller 22, each spout 17 of the steam introduction pipe 5 is in a fixed state.
The heated position of the pot body 1 with respect to the steam spouted from the nozzle changes from time to time, resulting in the same result as if the steam were spouted and diffused from a rotating nozzle.

Therefore, even if the steam outlet 17 is fixed, the pot body 1
The food is heated uniformly without being locally overheated, and stir-fried foods can be cooked well without burning.

Note that even if the steam introduction pipe 5 is rotated, the same effects as in the above embodiment can be obtained.

As described above, according to this invention, since the pot body having a steam jacket is supported horizontally rotatably, the tip of the steam introduction pipe is inserted from the center of the bottom of the steam jacket of the pot body,
By simply providing a spout that spouts steam in the radial direction at the insertion tip, the pot body can be heated uniformly, which simplifies the steam supply mechanism to the jacket and reduces the volume of the jacket. This has the effect of making the pot body more compact.
