DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a rice cooking device that houses a rice cooker.

Conventional configurations and their problems In recent years, the types and quantities of cooking equipment and food in the kitchen have increased, and there has been an increasing demand for storing them well and making effective use of space. It is beginning to change. However, regarding rice cookers, since steam is generated during rice cooking, there are problems such as condensation of steam, humidity, and temperature, so that rice cookers containing rice cookers have not been sufficient.

Hereinafter, the conventional rice cooking device as described above will be explained with reference to the drawings.

FIG. 1 shows a side cross section of a conventional rice cooking device. In FIG. 1, reference numeral 1 denotes the main body of the rice cooker, which has a rice cooker storage 5, in which a heating device 2 and a rice cooking pot 3 are housed. 4 is a lid that covers the top surface of the rice cooker 3. Said rice cooker storage 5
has an opening/closing door 6 on the front side, an intake port 7 is provided below the opening/closing door 6, and an exhaust port 8 is provided above the opening/closing door 6. Furthermore, an exhaust port 9 is provided at the upper rear side of the rice cooker storage 5. 10 in the figure is an exhaust passage provided on the back of the main body 1, and 11
is an exhaust port provided above the exhaust passage 10.

The operation of the rice cooking device configured as above will be explained below. When rice and water are put in a rice cooker pot 3 and the rice cooker is heated by a heating device 2 to cook rice, steam comes out from the gap between the lid 4 and the rice cooker pot 3 into the rice cooker storage 5. Furthermore, rice cooker storage 5
Come out inside. Further, the steam filling the rice cooker storage 5 is discharged from the exhaust port 8 and the exhaust port 9. The steam discharged from the exhaust port 9 is passed through the exhaust passage 1
0 and is discharged from the main body 1 through the exhaust port 11.

However, the above-mentioned configuration has the disadvantage that steam condenses on the inner wall of the rice cooker storage 5 and the inner wall of the opening/closing door 6, causing water droplets to adhere and easily corrode. Furthermore, when the steam condenses on the inner wall of the rice cooker storage 5, latent heat of condensation is released, which causes the rice cooker storage and the wall surface to become hot, which has a negative effect on other products near the rice cooker storage. However, there were restrictions on where the rice cooker could be installed, making it difficult to use.

Purpose of the Invention In view of the above-mentioned drawbacks, the present invention is designed to exhaust steam generated during rice cooking to the outside of the device body using a steam exhaust passage and a steam exhaust device provided inside the device body. To provide a rice cooking device that is easy to use and highly safe, since it does not cause dew to form on the inner wall or the like.

Composition of the Invention In order to achieve the above object, the present invention provides a rice cooker having a steam hole, a steam exhaust passage having a steam inlet, a steam exhaust device, and a drawer for storing the rice cooker in an apparatus main body. This drawer is equipped with a position detection device that is placed opposite the steam vent and the steam inlet, or the rice cooker is energized when the steam vent is outside the device. This is to prevent it from becoming too full.

Reference numeral 6 represents a drain hose for the steam cooling chamber 33, and reference numeral 37 represents a soup receptacle, which are detachably provided below the drawer 23. 38 is a thermal reed switch, which is installed on the top surface of the steam cooling chamber 33 and is electrically connected to operate the electric motor 31 when the temperature of the steam cooling chamber exceeds a certain level, and to stop the electric motor 31 when the temperature falls below a certain level. ing.

Next, the structure of the drawer 23 will be explained. 3
9 is a first roller provided at the rear of the drawer 23, and 40 is a second roller provided at the front of the device main body 21. The drawer 23 moves smoothly back and forth as the first roller 38 rotates relative to the partition plate 41 below the drawer 23 and the second roller 40 rotates relative to the drawer 23. 42 is a lever 4 electrically connected to the power outlet 28
It is a micro switch with 3 drawers and 23 drawers.
The drawer 23 moves forward and backward together with the drawer 23.
Reference numerals 44 and 45 denote first and second convex portions provided on the partition plate 41, which push up the lever 43 of the micro switch 42 to open and close the contacts of the micro switch 42.

The operation of the rice cooking device configured as described above will be explained below.

First, when cooking rice, open the drawer 23,
Open the lid 25 of the rice cooker 24 and add rice, water, and rice cooker 24.
Next, close the lid 25 of the rice cooker, connect the power plug 27 to the power outlet 28, close the drawer 23, and turn on the switch. When the drawer 23 is closed, the rice cooker 24 is in the normal position, the steam hole 26 and the steam inlet 34 are in opposing positions, and the first convex part pushes up the lever 43 and closes the contact of the micro switch 42. , the rice cooker 23 is
Power is supplied from the power plug 27, and rice cooking starts.
Steam gradually begins to be generated from the steam holes 26. The steam discharged from the steam hole 26 is transferred to the steam inlet 34.
and is led into the steam cooling chamber 33. Initially,
Since the wall surface temperature of the steam cooling chamber 33 is at room temperature, the steam condenses in the steam cooling chamber 33 and the steam cooling chamber 33
The wall temperature of the thermal reed switch 3 increases.
When the temperature of the steam cooling chamber 33 reaches or exceeds the operating temperature, the thermal reed switch 38 turns on, and the fan 32 rotates as the electric motor 31 operates, and the air cools the outer wall of the steam cooling chamber 33 while flowing into the exhaust passage 29.
and is exhausted to the outside of the apparatus main body 21 through the exhaust port 30. Therefore, since the wall surface of the steam cooling chamber 33 is cooled by air, some of the steam condenses on the inner wall, and the condensed water passes through the drain hose 36 and drains into the drip pan 3.
Water is stored at 7. Further, the steam that has not condensed in the steam cooling chamber 33 is exhausted from the steam exhaust port 35 provided on the top surface of the steam cooling chamber 35 to the exhaust passage 29, where it is mixed with the air flowing through the exhaust passage 29, and the temperature and relative humidity are adjusted. In the lowered state, the device body 2 is removed from the exhaust port 30.
1 Exhausted outside. When the rice cooking is completed and the rice is kept warm, the steam coming out of the rice cooker 24 disappears, and the wall temperature of the steam cooling chamber 33 begins to drop, and if the temperature drops below the operating temperature of the thermal reed switch 38, the thermal reed switch 38 turns off. ,
Electric motor 31 stops.

After rice cooking is completed, if you want to serve the finished rice, you can open the drawer 23 and open the lid 25. Since the convex part 2 pushes up the lever 43 again and closes the contact of the micro switch 42, the rice cooker 23 is powered by the power plug 27 and can be kept warm during serving.

If the user does not close the drawer 23 to the specified position, or if the user accidentally opens the drawer while cooking rice, the steam inlet 34 will not face the steam vent 26.
When the rice cooker 24 is inside the main body 21, the lever 43 of the micro switch 42 cannot be pushed up, so power is not supplied to the rice cooker 24. No steam is therefore discharged.

As described above, according to this embodiment, if the steam hole 26 of the rice cooker 24 does not face the steam inlet 34, the rice cooker 24 is not supplied with electricity, so that steam is not discharged into the main body 21 of the device. Because it is not possible to
The device main body 21 is never filled with steam.

Moreover, since the configuration is such that power is supplied even when the drawer 23 is opened and the rice cooker 24 is pulled out, the food can be kept warm even during serving, and the heat retention performance will not deteriorate.

In this embodiment, a micro switch is used as the position detection device, but the same effect can be obtained even if other position detection positions such as a reed switch are used.

Effects of the Invention As explained above, the present invention provides a position detection device in the drawer in which the rice cooker is placed, and turns on and off the power supply to the rice cooker depending on the position of the rice cooker. The steam that is generated fills the inside of the device, and there is no condensation on the inner walls, making it extremely safe.
