Referring now to FIG. 1, this is a view showing rice washing, in which the outer lid 11 is closed and the inner lid 12 is lifted up by the solenoid 19 to fit inside the upper end of the rice cooker 2. The rice cooker 2 is closed and the overflow drain 5 is open. When the flow of the washing water is described by arrows, the electromagnetic valve for drain 27 is closed, the electromagnetic valve for water supply 26 is opened, and the washing water is supplied from the water pipe 35 to the pipe 31.
, The washing water is ejected upward from the nozzle 4 fixed to the bottom center of the rice cooker 2 through the pipe 28 by driving the pump 13 in the forward rotation direction. Washing water is spouted laterally from a nozzle 4 fixed to a lower portion of the side wall, and dirty washing water is drained from an overflow drain port 5 provided at an upper side of the rice cooker 2. Drainage groove 14 provided on the outside
Is a diagram showing the state in which dirty washing water is drained from the drain pipe 15 to the outside of the rice cooker 1 through the drain pipe 15 by arrows.

Next, referring to FIG.
Is closed, the inner lid 12 is fitted inside the upper end of the rice cooker 2 and pushed down by the solenoid 19 to close the rice cooker 2, the overflow drain port 5 is closed and the steam vent 21 is closed.
Is a stretched state. The flow of draining water in the rice cooker 2 adjusted to the rice cooking water level by an arrow will be described. The electromagnetic valve 26 for water supply is closed, the electromagnetic valve 27 for drainage is opened, and the pump 13
The nozzle 4 fixed to the center of the bottom of the rice cooker 2 by driving in the reverse direction of rotation, and the nozzle 4 fixed to the lower side of the rice cooker 2
Then, the water in the rice cooker 2 is sucked (drained), enters the pump 13 through the pipe 18, is discharged from the pump 13, is sent to the solenoid valve 27 for drain through the pipe 31, and then passes through the drain hose 32. It is the figure shown by the arrow which the state drained outside the rice cooker 1 was shown.

Next, the hook 24 of the handle 25 of the rice cooker 1 configured as described above is removed from the locking portion 23 and the handle 25 is removed.
Is lifted, the outer lid 11 and the inner lid 12 open, and the rice cooker 2
Put the required amount of raw rice weighed (g or combined) into
5 is pressed downward, the hook 24 is locked by the locking portion 23, and the outer lid 11 abuts on the outer hook 34 and closes.
Is fitted to the inside of the upper end of the rice cooker 2 and closed, but the overflow drain 5 is open.

Then, the required washing time (g or total) of the raw rice put into the rice cooker 2 is compared with the required washing time obtained in advance from the relationship data between the amount of the raw rice and the washing time. When the required cleaning time is set on a timer switch (not shown) of the operation panel 33 of the determination means (not shown), the water supply solenoid valve 26 is opened, and the drainage solenoid valve 27 is closed at this time to supply the pressurized water. The pump 13 of the means 3 is activated in the forward rotation direction, and pressurized water is jetted from a required number of nozzles 4 fixed to a required position of the rice cooker 2, and the raw rice put into the rice cooker 2 is a stream of pressurized water. While being stirred in the rice cooker 2, the washing water is washed away from the required number of overflow drains 5 arranged at required positions in the upper part of the rice cooker 2 together with the washing water which is contaminated with the debris and debris adhered to the surface of the raw rice by the washing water. This dirty washing water is drained by drain pipe 1 Overflow drained into the drainage groove 14 which is connected to be drained to the outside of the rice cooker 1.

When a timer switch (not shown) of the washing time determining means is turned off, the raw rice is washed, the pump 13 of the pressure water supply means 3 is stopped, the water supply electromagnetic valve 26 is closed, and the drainage electromagnetic valve is closed. The valve 27 is opened, the pump 13 is started in the reverse rotation direction, the water in the rice cooker 2 is sucked (drained) from the nozzle 4, and the water is drained from the drain valve 27 to the outside of the rice cooker 1 through the drain hose 32. The amount of water (water level) in the rice cooker 2 containing the rice washes was determined in advance by using the relationship between the amount of rice washed and the amount of rice water (water level) that could be optimally (deliciously) cooked. When the water is drained to the position of the water level sensor 16 attached to the required position of the required cooking water level with respect to the required rice washing amount of the kettle 2, the water level sensor 16 detects and activates the ultrasonic wall level switch (not shown) to stop the pump 13. Stop draining Rukoto by, is adjusted to the water level required cooking water level in the cooking pot 2, is drained electromagnetic valve 27 for water supply electromagnetic valve 26 is opened to close.

The overflow drain opening / closing means 9
At this time, the overflow drain port 5 is closed by pushing down the inner lid support pipe 20 which has the inner lid 12 engaged and supported by the solenoid 19 (the inner lid 12 is in a state below the overflow drain port 5). Steam vent 21 consisting of
Is a stretched state.

When the inside lid 12 closes the overflow drain port 5 by the overflow drain opening / closing means 9 after being adjusted to the required rice cooking water level, an experiment was conducted in advance to cook the rice washing adjusted to the required rice cooking water level. The heating coil 18 and the rice cooker 2 for heating the rice cooker 2 by operating a timer switch (not shown) of the heating means 10 with respect to the required rice washing amount obtained from the relation data between the rice wash obtained and the heating temperature and the heating time.
Is cooked by the temperature sensor 17 in contact with.

The present invention can also be used for a gas cooker that heats a rice cooker by the heat of gas.

When all the cooked rice in the rice cooker 2 is to be eaten or the inside of the empty rice cooker 2 having no remaining rice grains transferred to another container is to be washed, a required number of cleaning members having a required shape are used. (For example, sardines, etc.) is put into the rice cooker 2 and the outer lid 11 and the inner lid 12 are closed. At this time, the overflow drain port 5 is opened. When the obtained required rice cooker washing time is set in the timer switch of the operation panel 33, the water supply solenoid valve 26 is opened, and at this time, the pump 13 of the pressure water supply means 3 is rotated in the forward rotation direction while the drainage solenoid valve 27 is closed. The cleaning member (not shown) injected into the rice cooker 2 with pressure water spouted from the nozzle 4 is stirred in the rice cooker 2 by the water flow of the pressure water,
At this time, the cleaning member rubs the rice scum (glued or small particles) adhered to the bottom and side surfaces of the rice cooker 2 and is washed off by the washing water flow and is washed away from the overflow drain 5 together with the dirty washing water. When the timer switch of the set required rice cooker washing time is turned off, the inside of the rice cooker 2 is washed, the outer cover 11 and the inner cover 12 are opened, the washing member is taken out, and the method of washing the inside of the rice cooker 2 is in a preferable mode. is there.

Further, at the time of washing rice, washing water discharged from the drain pipe 15 to the outside of the rice cooker 1 is collected in a water tank (not shown) or the like, and fresh water filtered by a filter or the like is supplied to a water supply solenoid valve 26 with a hose or the like. Connecting and circulating and reusing is a preferred embodiment because it saves water.

The embodiment of the present invention has been described above. However, the configuration method, the configuration device, the configuration contents, the dimensions, the materials, the shapes, and the relative arrangements of the components described in this embodiment are not described. Unless otherwise specified, the scope of the present invention is not intended to be limited to them only, but is merely an illustrative example, and the present invention is not limited to such an embodiment. It goes without saying that the present invention may be implemented in various modes without departing from the spirit of the present invention.
