It is better to wash rice with water, rinse,
By repeating the drainage several times, the white turbidity of the water disappears quickly and the washing of the rice to cook the rice more deliciously is completed.

For the rice grains that have been washed, the wheels 1 can be opened by opening the downward door 37 and pulling out the table basket 13.
5 rotates on the rail 16 and the rice basket 13 is taken out of the machine. Open the lid 29 and transfer it from the rice basket body 21 to the inner pot of the rice cooker, and add an appropriate amount of water to prepare rice. Complete.

In general households, the rice grains after washing the rice are once transferred to a water basket to prevent the rice grains from absorbing water,
Although it can be seen that the deterioration of water due to spoilage is prevented, the present invention does not need to transfer to another container after washing rice because the washing basket 21 itself has the function of a water basket.

Further, in the present invention, a control program for washing rice is newly provided, but rice may be washed in the rinse course 32 according to the program selection III.

Embodiment 2 FIGS. 4 to 5 show a second embodiment of the washed rice basket 21 according to the present invention, in which 25 is a main body having a construction similar to boiling noodles and 43 is an annular wire 42. It is a net formed by winding the peripheral part on a pan and drawing it into a pan shape, as shown in FIG.
A wire size B = 0.4 and a mesh size A = 1.6 mm are selected, and the mesh size that prevents passage of a width of 2.5, a thickness of 2 and a length of 5 mm, which is the size of a common rice grain. Is adopted,
Reference numeral 44 is a line for reinforcing the net, one end of which is wound around the wire 42, the trunk of which extends along the outer periphery of the bottom of the net, and the other end of which is wound around the wire 42. Two are used, but several are often used at equal intervals in order to improve the reinforcing strength. 46 is a recess 45 at the upper end.
Is an annular outer ring having a wire 42 net 43
The end portions of the end linear strips 44 are strongly crimped and sandwiched to form the main body 25. Reference numeral 51 is an annular inner ring having a convex portion 53 at the lower end and a handle portion 52 at the outer peripheral portion. 29 are configured. The washing basket 21 is constructed by using a stainless steel material which is rust-resistant so that the convex portion 53 of the lid 29 and the concave portion 45 of the main body 25 can be detachably fitted. To set in the washing tank 3, the tableware support bar 14 of the tableware basket 13
It just needs to be placed on top of it, and it does not interfere with the function even if it is slightly inclined.

In this embodiment, since the net is composed of fine wires having a circular cross section, there is little pressure loss when the sprinkler jet water passes, so a more effective rice washing effect can be expected.

Embodiment 3 FIG. 6 shows a third embodiment of the washed rice basket 21 according to the present invention, in which an upper end of a pot-shaped main body 25 having a small hole 30 for preventing passage of rice grains is annular. The inward flange 54 is integrally formed and a plurality of legs 55 are provided on the lower surface. When setting in the washing tank 3, after removing the dish basket 13 from the machine, the legs 55 of the rice basket 21
It can be prepared to achieve the purpose by placing it on the rail 16 on the inner wall of the cleaning tank. This implementation plan eliminates the need to open and close the lid when loading and discharging rice grains without the lid.

[0022]

As described above, according to the present invention, it is possible to wash rice by spraying the water sprayed from the dishwasher on the rice grains in the washing basket. The apparatus is inexpensive and the hands are not wet at home. It has the effect of easy rice washing.

Further, since the contact time between the rice grains and the washing water in which the rice bran is melted and the rice grains is short, it is difficult for the rice grains to permeate into the rice grains. It does not spoil the appearance of the rice grains, and it is convenient because it eliminates the need to transfer the rice grains to the water basket after washing the rice.
