Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a rice cooking device used on a daily basis in general households.

BACKGROUND ART A conventional rice cooking device of this type had a structure as shown in FIG. That is, it consists of a rice cooking section 1 that cooks rice, and a steam exhaust section 2 that discharges steam generated during rice cooking to the outside of the device.The rice cooking section 1 includes a heating element (not shown) and a pot (not shown). (not shown), and the upper opening of the rice cooking section 1 is covered by a lid 4 whose one end is pivotally supported on the rice cooking section 1 by a hinge 3. Further, the lid body 4 is provided with a steam cylinder 6 for discharging steam generated within the pot.

In addition, the steam exhaust section 2 has a blower fan 9 disposed in an exhaust passage 8 which opens at both ends as an intake port 6 and an exhaust lower, and a steam inlet 10 at a position facing the steam cylinder 6 of the exhaust passage 8. The steam introduced from the steam inlet 10 exchanges heat with the air taken in by the blower fan 9 at the heat sink 11, and a part of the steam is condensed and stored in the water storage tank 13 via the drain hose 12. The remaining steam is mixed with air at the end of the heat sink 11 and discharged as low-temperature air.

Problems to be Solved by the Invention However, with such a structure, if the amount of rice and water to be put into the pot is incorrect, for example, if the rice is cooked with too much water, a larger amount of "oneba" than in the steam cylinder 5 may be produced. Flows out onto the lid 4, and the "snake" flows downward and accumulates, which not only requires cleaning, but also
It was extremely unsanitary.

In addition, the condensed water that has condensed in the steam processing section drips from the steam inlet 10 onto the lid 4 due to vibrations, etc., and either remains as water droplets or falls along the periphery of the lid 4. It was very easy to get dirty and was unsanitary.

The present invention has been made to solve these problems, and provides a rice cooking device that can effectively dispose of condensed water caused by steam generated during rice cooking and "slug" that is discharged during misuse. The purpose is to provide the following.

Means for Solving the Problems In order to solve the above problems, the present invention provides a rice cooking section with an open top surface, and a lid having one end pivotally attached to a support shaft so as to cover the top opening of the rice cooking section. and a steam cylinder vertically penetrating the lid, the lid surrounding the steam cylinder;
A water catchment area that is lower than the top surface of the lid body, and a drainage channel that communicates from this water catchment area to the water storage tank are provided, and this drainage channel is provided so as to penetrate through the lid body, and its terminal opening faces the exposed basin. Further, a vapor deposition suction port of a vapor processing section equipped with an air blower is provided above the steam cylinder, and a projected portion of the vapor suction port is included in the catchment area.

Further, in the present invention, the drainage channel is provided closer to the support shaft than the steam cylinder, and an eave-shaped waterproof wall is provided above the drainage channel, and the water storage tank is detachably attached to the rice cooking section. This water storage tank is connected to the upper basin, which houses the dew pan, through an overflow channel.

Operation Steam generated in the rice cooking device configured as described above is guided from the steam cylinder through the steam suction port into the steam processing section by driving the blowing means, and is then discharged to the outside of the rice cooking device. The condensed water condensed inside the steam suction port drips into a catchment area provided on the lid, passes through a drainage channel, and is stored in a dew tray. In addition, when a user accidentally cooks rice with too much water, the ``oneba'' etc. that are discharged are collected in the dew tray from the catchment area via the drainage channel, similar to the condensation water mentioned above. Since the "Oneba" that cannot be stored in the rice cooker is collected in the water storage tank, it is possible to prevent the "Oneba" from being scattered inside the rice cooker.

In addition, the drainage channel is located closer to the support shaft of the lid than the steam cylinder, and an eave-shaped waterproof wall is provided above this drainage channel, so even if the lid is heavily cleared, ,
Dew and debris on the water collection platform do not go over the drainage canal, but instead hit the waterproof wall and are guided into the drainage canal. This can prevent dew and "sticky" from scattering.

Next, the operation of the rice cooking device configured as described above will be explained.

First, place the pot 24 containing rice and water on the heating element 23,
After closing the lid 26 and covering the rice cooking section 21, when the switch operation section 37 is turned on, the control circuit 39 energizes the heating element 23 and rice cooking is started. When the heating element 23 is heated, the water temperature in the pot 24 rises, and the generated steam is discharged through the steam cylinder 34. This steam enters the steam processing section 4o through the suction port 47 facing the steam cylinder 34. In this case, first, the steam contacts the thermostat 48 and heats it, so that the contacts of the thermostat 48 are turned on. As a result, the motor 44 electrically connected to the thermostat 48 is driven, and the turbo type fan 42 is driven.
The impeller 41 rotates. As a result, steam is sucked in from the suction port 47, and at the same time, steam is sucked into the ventilation hole 60 from the suction port 62.
Air is sucked through. And turbo fan 42
The steam sucked into the impeller 4 inside the fan case 43
1. As a result, a portion of the steam condenses, and the remaining steam is discharged from the outlet 45 to the outside of the cabinet 61. In this case, the condensed water drips directly from the suction port 47 into the catchment area 36 and passes through the drainage channel 36 to the dew pan 27.
Water is stored in

As the rice cooking progresses, the water in the pot 24 disappears, which causes the temperature of the pot 24 to rise rapidly, which is detected by the pot sensor 38, and the control circuit 39 stops energizing the heating element 23. Cooking is completed. When this rice cooking is completed, the amount of steam discharged from the steam cylinder 34 will decrease, so the contact of the thermostat 48 will be turned OFF, and the motor 44 will be turned off.
stop.

After the rice cooking is completed, when the rice cooking section 21 is pulled out and the lid 26 is opened, the pot 24 is exposed, so that serving can be performed. At this time, the dew attached to the inner surface of the lid 26 is removed from the lid 26.
6 is opened, the dew falls along the inner surface of the lid 26, is collected in the dew guide 29, and flows through the water outlet 30 into the dew pan 2.
Collected at 7.

Further, the dew remaining in the catchment area 36 of the lid 26 is removed from the lid 26.
By opening the , the water is forcibly guided to the drainage channel 36 .

At this time, even if the lid body 26 is strongly opened, since the eave-shaped waterproof wall 35a is provided on the support shaft 26 side of the drainage channel 35, dew will not be scattered.

In the above description of the operation, the normal usage state has been explained, but next we will explain the operation when the rice is used incorrectly, in which the amount of rice and water put into the pot 24 is incorrect, and the rice is cooked with too much water.

Cooking rice with a very high amount of water is equivalent to cooking so-called "porridge" over high heat, and in this case, a large amount of "boiled rice" flows out from the steam cylinder 34. This "snake" is collected from the drainage channel 36 along the catchment area 36 around the steam cylinder 34 into the dew pan 27, so it is not scattered from the lid body 25 into the gear vignette 51. Generally, the dew pan 27 has a volume that is large enough to accommodate the normal amount of frost.
When "Oneba" enters, the water becomes full. The "oneba" overflowing from the dew tray 27 passes through the overflow channel 31 to the water storage tank 3.
2, it is possible to prevent the "snake" from flowing into the gear vignette 51. Also, the dew tray 27
．． Since the water storage tank 32 is configured to be detachable, it can be easily cleaned.

Effects of the Invention As is clear from the description of the above embodiments, according to the present invention, there is a water catchment area that is lower than the top surface of the lid body so as to surround the steam cylinder provided on the lid body of the rice cooking section, and A drainage channel is provided that communicates with the water storage tank, and this drainage channel is provided through the lid body, with its terminal opening facing the dew pan, and is located above the steam cylinder, and is equipped with a ventilation means. In addition to providing a suction port for the processing section, the projected portion of this steam suction port is included in the catchment area, so that the condensed water that condenses inside the steam suction port during rice cooking drips into the catchment area. , can be stored in a dew pan through a drainage channel.

In addition, the waste that is discharged when a user accidentally cooks rice with too much water can be stored in the dew tray from the catchment area via the drainage channel, similar to the condensed water mentioned above. I can do it,
The ``Oneba'' that cannot be stored in the rice cooker is collected in the water storage tank, which prevents ``Oneba'' from scattering inside the rice cooker, making it extremely hygienic. be.

In addition, the "Oneba" that overflows from the dew pan is stored in a separate water storage tank, so the volume of the dew pan that is used every day is small enough to accommodate the dew that is discharged during normal use. As a result, usability is greatly improved.

Furthermore, the drainage channel is located closer to the support shaft of the lid than the steam cylinder, and an eave-shaped waterproof wall is provided above this drainage channel, so even if the lid is strongly opened, Therefore, the dew and "Oneba" on the water collection branches will not reach the drainage canal, but will hit the waterproof wall and be guided into the drainage canal, which will prevent the dew and "Oneba" from scattering. It is something that can be prevented.
