And, in outer pot 3, on by near the circumference central between the end position of near the position the periphery of bottom and described truncated cone shape portion,, be formed with the first outer pot tap 32 of two tiny mesh-shapes (for example about 0.02～0.5mm) with across bottom centre and opposed mode.
And, on the straight line of each first outer pot tap 32 of the connection in outer pot 3, and, be formed with the second outer pot tap 33 (aperture is about 15～25mm) in the outer fix of each first outer pot tap 32 and on the side of outer pot 3.
The first outer pot tap 32 is connected with outlet 1c on being located at rice cooker body 1 via the first drain passageway 32a, and the second outer pot tap 33 is connected (with reference to Fig. 1) via leftovers incorporating section 1d with outlet 1c from the second drain passageway 33a.
As shown in Figure 5, interior pot 4 is objects that the general cylindrical shape shape at the end is arranged, and is formed with semi-spherical shape portion on its bottom center part, and this semi-spherical shape portion has the shape that is roughly hemisphere that pot 4 opening directions inwardly slowly tilt and rise.
And, in interior pot 4, on through near the circumference the central authorities between the end position of near position the periphery of bottom and described semi-spherical shape portion, and, be formed with the first interior pot tap 41 of two tiny mesh-shapes (for example about 0.02～0.5mm) with across the opposed mode of bottom centre.
This in first pot tap 41 be in outer pot 3, to have taken under the state of interior pot 4, with the roughly the same circumferential position of the first outer pot tap 32 on formed.
And, in interior pot 4, from connect each in first the straight line of pot tap 41 changed on the straight line of phase place with predetermined angular, and, be formed with pot tap 42 (aperture is about 15～25mm) in second in the outer fix of each pot tap 41 in first and on the side of interior pot 4.
Like this, pot is 4 the time in rotation, can form the zone (hereinafter referred to as second area) that the zone (hereinafter referred to as the first area) that the first outer pot tap 32 overlaps with the first interior pot tap 41 and the second outer pot tap 33 overlap with the second interior pot tap 42 independently.
At this moment, set the phase changing capacity (for example being about 15～25 °) between pot tap 42 in the described first interior pot tap 41 and second, so that in each zone, can not form another zone when regional forming one, when for example the first outer pot tap 32 overlaps with pot tap 41 in first, avoid the second outer pot tap 33 to overlap with pot tap 42 in second.
Thus, constituted deliverying unit 10.
Here, the structure of interior pot 4 is when forming first area and second area, by central processing department A its rotation to be controlled to be, earlier formation first area (being counterclockwise in Fig. 5).
In addition, for convenience of description, in Fig. 1, be formed with first area and second area simultaneously.
Therefore, described first area and second area can not form simultaneously, in outer pot 3, taken under the state of interior pot 4, as long as the second interior pot tap 42 can be formed, with height roughly the same get final product of the second outer pot tap 33, the position of pot tap 41, the second interior pot tap 42, the first outer pot tap 32, the second outer pot tap 33 in first is not particularly limited at bottom place.
For example, can form as follows, the i.e. position of the second outer pot tap 33, be formed on the outer fix of the first outer pot tap 32 shown in Fig. 6 (a) and on the bottom, in second the position of pot tap 42 be formed on shown in Fig. 6 (b) first in pot tap outer fix and on the bottom, and be positioned at from the straight line that connects each first pot of tap 41 and changed on the straight line of phase place with predetermined angular.
And, in the mode of Fig. 4 and Fig. 5 and Fig. 6, also can adopt opposite mode, i.e. pot tap 41 in the outside forms the first outer pot tap 32, first, and in the inboard forms the second outer pot tap 33, second pot tap 42.
In addition, be preferably formed for, as shown in Figure 2, the open end of interior pot 4 becomes the cross section to be roughly word shape towards the outside curve of radial direction, the open end of outer pot 3 also becomes the J word shape towards the outside curve of radial direction, and the edge part of interior pot and outer pot is involved in mutually.This is owing to can bring into play following effect, promptly prevent to sneak into foreign matter in the gap between outer pot 3 and interior pot 4 and prevent described hereinafter in pot matting washing agent or the steam that is dissolved with residue invade in the described gap.In addition, pot and the part that is involved in mutually of outer pot in being formed, owing to considering that rotating the friction that causes is formed the gap with some degree, and the friction that causes for fear of rotation of the end of sweep and be formed circular arc.Be preferably formed near the peristome of outer pot 3 and interior pot 4 into, to tilt and each peristome enlarged gradually in order to constitute, but vertical form also no problem.
In addition, in Fig. 1, Fig. 2, the preferred implementation of the open end of pot 4 and outer pot 3 in illustrating, and in Fig. 4, Fig. 5 and hereinafter described Fig. 8 and Figure 12, other embodiments of the open end of pot 4 and outer pot 3 in illustrating.
And in the substantial middle portion of the bottom outer surface of interior pot 4, the axle that has formed with hereinafter described interior pot rotary unit carries out chimeric fitting portion 43.
