Description

Description: FIELD OF THE INVENTION The present invention relates to a rice cooker that is routinely used in homes and the like.

2. Description of the Related Art A conventional rice cooking device of this type has a structure as shown in FIG. That is, it is composed of a rice cooking unit 1 for cooking rice and a steam discharge unit 2 for discharging steam generated during rice cooking to the outside of the device. Inside the rice cooking unit 1, a heating element (not shown) and a pot (not shown) are provided. (Not shown), and the upper opening of the rice cooking unit 1 is covered with a lid 4 whose one end is pivotally supported by a hinge 3. Further, the lid body 4 is provided with a steam cylinder 5 for discharging steam generated in the pot.

Further, the steam discharge part 2 has a blower fan 9 disposed in an exhaust passage 8 whose both ends are opened as an intake port 6 and an exhaust port 7, and the steam inlet port 10 is located in the exhaust passage 8 at a position facing the steam cylinder 5. The steam introduced from the steam introduction port 10 is heat-exchanged with the air sucked by the blower fan 9 at the radiator plate 11, and a part of the steam is condensed water from the drain hose 12 to the water storage tank 13 And the remaining steam is mixed with air at the end of the heat dissipation plate 11 and discharged as low temperature air.

However, with such a structure, when the amount of rice and water put in the pan is wrong, for example, when rice is cooked with a large amount of water added, a larger amount of "Onba" than the steam cylinder 5 is used. Not only needs to be cleaned, because the “spills” will flow out onto the lid body 4, and the “nemba” will flow down and accumulate as it is.
It was very unsanitary.

Further, the dew condensation water condensed in the steam treatment unit drops on the lid 4 from the steam inlet 10 due to vibration or the like and remains as a water drop as it is, or falls along the peripheral portion of the lid 4, which is extremely dangerous. It was easy to get dirty and became unsanitary.

The present invention has been made to solve such a problem, and is capable of effectively treating dew condensation water due to steam generated during rice cooking, "oneba" discharged during misuse, and the like. It is intended to provide.

Means for Solving the Problems In order to solve the above problems, the present invention relates to a rice cooking unit having an upper surface opened, and a lid body having one end pivotally mounted by a support shaft so as to cover the upper surface opening of the rice cooking unit. , A steam cylinder vertically penetrating this lid, and the lid so as to surround the steam cylinder,
A catchment area that is lower than the upper surface of the lid and a drainage channel that communicates with the water storage tank from this catchment area are provided, and this drainage channel is provided so as to penetrate the lid, and its end opening faces the dew receptacle. Further, a vapor deposition suction port of a steam processing unit provided with a blower is provided above the vapor cylinder, and a projected portion of the vapor suction port is included in the water collecting area.

Further, according to the present invention, the drainage channel is provided on the support shaft side of the steam cylinder, and an eave-shaped waterproof wall is provided above the drainage channel, and the water storage tank is detachable from the rice cooking section. The water storage tank and the upper frame for accommodating the dew receptacle are connected to each other through an overflow channel.

Action The steam generated in the rice cooker configured as described above is guided to the inside of the steam processing unit from the steam cylinder through the steam suction port by the driving of the blower, and then discharged to the outside of the rice cooker. The dew condensation water that has condensed inside the steam inlet is dropped into a water collecting area provided on the lid, and is stored in a dew receiver through a drainage channel. In addition, “oneba” etc., which is discharged when the user accidentally cooks rice with a large amount of water addition, is also stored in the dew receptacle from the catchment area via the drainage channel, like the above-mentioned condensed water, and Since the "oneba" that cannot be stored in the dew tray is collected in the water storage tank, it is possible to prevent the "oneba" from being scattered in the rice cooker.

Also, since the drainage channel is located closer to the support shaft side of the lid than the steam cylinder, and the eave-shaped waterproof wall is provided above this drainage channel, even when the lid is strongly opened, Dew on the catchment area and "oneba" hit the waterproof wall and are guided into the drainage channel without getting over the drainage channel.

Next, the operation of the rice cooker thus configured will be described.

First, place a pot 24 containing rice and water on the heating element 23,
After closing 25 and closing the lid of the rice cooking unit 21, when the switch of the switch operation unit 37 is turned on, the control circuit 39 energizes the heating element 23,
Cooking rice starts. When the heating element 23 is heated, the water temperature of the pot 24 rises, and the generated steam is discharged from the steam cylinder 34. This steam enters the steam processing unit 40 through the suction port 47 facing the steam cylinder 34. In this case, first the steam contacts the thermostat 48 and heats it, so
The 48 contacts are turned on. As a result, the motor 44 electrically connected to the thermostat 48 is driven, and the impeller 41 of the turbo fan 42 rotates. As a result, the steam is sucked from the suction port 47, and the air is sucked from the suction port 52 through the ventilation hole 50. And a turbo fan
The steam sucked into the fan 42 is transferred to the impeller 41 inside the fan case 43.
Is stirred by. As a result, some of the steam will condense,
The remaining steam is discharged from the air outlet 45 to the outside of the cabinet 51. In this case, the condensed water is directly collected from the suction port 47.
It is dripped on 36 and is stored in the dew receptacle 27 through the drainage channel 35.

As cooking rice progresses, the water in the pot 24 disappears, which causes the temperature of the pot 24 to rise sharply, which is detected by the pot sensor 38, and the control circuit 39. The power supply to the heating element 23 is stopped, and the rice cooking is completed. When this rice cooking is completed, the steam discharged from the steam cylinder 34 also decreases, so the thermostat 48
The contact of turns OFF and the motor 44 stops.

After completion of this rice cooking, when the rice cooking section 21 is pulled out and the lid 25 is opened, the pan 24 is exposed, and serving can be performed.
At this time, the dew that has adhered to the inner surface of the lid 25 drops along the inner surface of the lid 25 when the lid 25 is opened, and the dew guide 29
It is collected in the dew pan 27 from the water outlet 30. Further, the dew remaining in the water collecting area 36 of the lid 25 is forcibly guided to the drainage channel 35 by opening the lid 25. At this time, the lid
Even if 25 is strongly opened, since the eave-shaped waterproof wall 35a is provided on the support shaft 26 side of the drainage channel 35, dew does not scatter.

In the above description of the operation, the normal use state has been described, but next, the operation at the time of incorrect use in which the amount of rice and water put in the pan 24 is incorrect and rice is cooked with a large amount of water addition will be described.

To cook rice with a large amount of water addition means to cook so-called "porridge" with high heat, and in this case, a large amount of "oneba" flows out from the steam cylinder 34. Since this "Oneba" is collected from the drainage channel 35 to the dew receptacle 27 along the water collecting area 36 around the steam cylinder 34, the lid 25 moves to the cabinet.
There is no scattering within 51. In general, the dew tray 27 has a capacity for accommodating a normal amount of dew, and therefore, when the "oneba" enters, it becomes full of water. And "Oneba" overflowing from dew tray 27
Are collected in the water storage tank 32 through the overflow channel 31,
It is possible to prevent the “oneba” from flowing out into the cabinet 51. Further, since the dew tray 27 and the water storage tank 32 are configured to be removable, cleaning can be easily performed.

EFFECTS OF THE INVENTION As is apparent from the description of the above embodiments, according to the present invention, a water collecting area that is lower than the upper surface of the lid so as to surround the steam cylinder provided in the lid of the rice cooking unit, and from this water collecting area A drainage passage communicating with the water storage tank is provided, the drainage passage is provided through the lid body, the end opening of the drainage passage is exposed to the dew receiver, and the steam is provided above the steam cylinder and has a blower means. Since the suction port of the processing unit is provided and the projected portion of this steam suction port is included in the water collection area, the dew condensation water that has condensed inside the steam suction port during rice cooking will drip into the water collection area. , Can be accommodated in the dew receptacle through the drainage channel. In addition, “oneba” etc., which is discharged when the user mistakenly cooks rice with a large amount of water addition, can be stored in the dew receptacle from the catchment area via the drainage channel as with the above-mentioned condensed water. "Oneba" that can be done and cannot be stored in the dew tray is collected in the water storage tank, so it is possible to prevent "Oneba" from being scattered in the rice cooker, which is very hygienic. It is a thing.

In addition, the "oneba" that overflows from the dew tray is stored in a separate water storage tank, so the volume of the dew tray used daily should be small enough to accommodate the dew discharged during normal use. As a result, the usability is greatly improved.

Furthermore, since the drainage channel is located closer to the support shaft side of the lid than the steam cylinder, and the eave-shaped waterproof wall is provided above this drainage channel, even when the lid is strongly opened. , Dew and "oneba" on the catchment area will be guided to the drainage channel by hitting the prevention wall without getting over the drainage channel, thereby preventing scattering of dew and "oneba". Is something that can be done.
