Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a configuration of a rice cooker that is used daily in a general household.

(Prior Art) A conventional rice-cooking device of this type has a structure as shown in FIG. 4, as disclosed in, for example, Japanese Utility Model Publication No. 57-53455.

FIG. 4 is a partially cutaway side view showing a conventional rice cooker.

That is, the pan 42 is housed in the device body 41, and the lid 43 is pivotally supported on the upper side of the device body 41 on one side surface of the device body 41 by the hinge 44.

The lid body 43 is provided with a steam passage chamber 45 for discharging the steam generated from the pan 42 to the outside of the apparatus main body 41, and a steam outlet hole 46.
Further, the structure is such that the steam is discharged to the outside of the device main body 41.

That is, when rice and water are put in the pot 42 and heated to cook rice, the water in the pot 42 boils and steam is generated. This steam passes through the steam passage chamber 45 and is discharged from the steam outlet hole 46.

(Problems to be solved by the invention) However, in such a structure, since the steam discharged is at a high temperature, there is a risk that the user may get burned when touching the steam by mistake, and the safety is high. There was a problem with sex.

Furthermore, since the steam is blown upwards, it is not possible to place other objects above the rice cooker, which requires a large space for cooking rice, and when it is installed near the wall, steam will condense on the wall surface, There was a drawback that it was not easy to use due to restrictions on the installation location such as damaging the wall surface.

(Means for Solving the Problems) In order to solve the above problems, according to the present invention, an exhaust passage and a blower are provided in a lid that covers an upper surface of a device main body to mix and discharge steam generated during rice cooking with air. In addition to the above, a recess is formed by recessing the edge of the upper surface of the main body of the apparatus inward, and one end of the exhaust passage is opened so as to face the recess to serve as an intake port.

(Operation) With the above configuration, the steam generated during rice cooking is guided to the exhaust passage in the lid body and mixed with the air sucked from the intake port by the blower, and a part of the steam is condensed in the exhaust passage and remains. Vapor becomes low temperature and is discharged from the exhaust port.

The lid can be opened and closed by inserting a hand into the recessed portion on the upper edge of the apparatus main body, that is, the intake port and lifting the lid.

(Embodiment) An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a side sectional view of a rice cooker in one embodiment of the present invention. 2 is a partially cutaway plan view of the rice cooking device, and FIG. 3 is a perspective view of the rice cooking device.

1 to 3, 1 is a device main body having an open top surface, 2 is an upper frame that forms the upper surface of the device main body 1, 3 is a heating element provided in the device main body 4, and 4 is a pan that can be freely attached and detached. It is installed.

Reference numeral 5 is a switch operating portion, 6 is a lid that covers the opening surface of the apparatus main body 1, 7 is an inner lid that covers the top surface of the pan, and has a hole 7a through which steam passes, and is attached to the lid 6.

8 is a dew tray provided on the same surface as the switch operating portion 5,
It has an opening 9 on its upper surface and is detachably mounted. In the upper frame 2, a groove 10 provided on the outer periphery, a guide hole A11 communicating with the opening 9 of the dew receiver 8 from the groove 10, and an upper surface edge portion flush with the switch operating portion 5 are depressed inward. Recess
Having twelve.

Reference numeral 13 denotes a hinge portion for pivotally supporting the lid body 6 on one side of the apparatus main body 1, 14
Is a hook portion provided on the opposite side of the hinge portion 13. Reference numeral 15 denotes an exhaust passage provided in the lid 6, one end of which is opened as an exhaust port 16 on the same surface as the switch operating portion 5 of the lid 6, and the other end of which is an intake port in a recess 12 provided in the upper frame 2. It is open as 17. Reference numeral 18 denotes a blower provided in the exhaust passage 15 on the side of the intake port 17.

Reference numeral 19 is a steam guide that guides the steam generated in the pan 4 to the exhaust passage 15, and is provided between the air blower 18 and the exhaust port 16 and includes a diffusion plate 20.
Causes the vapor to diffuse.

Reference numeral 21 is a guide hole B communicating with the exhaust passage 15 and the groove 10 provided in the upper frame 2, and is provided on the hinge portion 13 side.

22 is a pan sensor that detects the temperature of the bottom of the pan 4, and 23 is a heat insulating material. A packing 24 is provided on the lid body 6, and when the lid body 6 is closed, it is pressed against the outer periphery of the pot 4 to prevent vapor leakage.

The operation of the rice cooker configured as above will be described below.

Put rice and water in the pan 4, and operate the switch operation unit 5 to turn on the switch. Then, power is supplied to the heating element 3 and the blower 18 operates.

The blower unit 18 sucks air from the intake port 17 and generates a flow of airflow to be exhausted to the exhaust port 16. During this time, the water in the pan 4 heated by the heating element 3 becomes steam, passes through the steam passage hole 7a of the inner lid 7, and is further exhausted by the steam guide 19 in the exhaust passage 15
Be guided inside.

Here, the exhaust gas diffused by the diffusion plate 20 is blown by the blowing means 18
Is mixed with the air flow and discharged from the exhaust port 16.

When rice cooking progresses and water in the pan 4 evaporates, the bottom temperature of the pan 4 rises. The pan sensor 22 detects this temperature, and when the temperature reaches a predetermined temperature, power supply to the heating element 3 is stopped.

The air blower 18 automatically stops after a certain period of time after the rice is cooked in order to exhaust the steam due to the residual heat.

After the rice is cooked, the hook portion 14 is released, a hand is put in the concave portion of the upper frame 2, and the lid body 6 is lifted to open the upper surface of the apparatus main body 1 so that it can be served.

At this time, the water droplets that have condensed on the inner lid 7 and the inner surface of the lid 6 drop on the groove 10, and the water droplets that have condensed on the exhaust passage 15 drop on the groove 10 through the guide hole B21.

The dew collected in the groove 10 in this way is collected in the dew receiver 8 through the guide hole A11. The dew receiver 8 can be easily attached and detached by pulling it out to the front, and the collected dew can be collected by the user. You can throw it away.

(Effect of the invention) As is apparent from the above description of the embodiments, according to the present invention, the exhaust passage and the air blower provided in the lid of the rice cooker mix the steam generated during the rice cooker with the air, As low-temperature moist air, it can be dispersed outside the rice cooker body and exhausted, so there is no risk of burns etc. even if the user accidentally touches the vicinity of the exhaust port, and steam is directed in the forward direction. By exhausting, the upper space of the rice cooker can be effectively used, and by discharging as dispersed and moist air, it is possible to prevent dew condensation on the wall surface near the rice cooker.

Further, by providing the intake port on the handle of the lid, there is no unnecessary hole on the outer appearance, and it is possible to prevent the intrusion of dust and the like.

Furthermore, by arranging the intake port on the front of the main unit,
Even if installed on the wall, there is no danger of blocking the intake port, which is very safe.

When the apparatus main body is provided with the rail mechanism and the apparatus main body is housed in the cabinet, it is not necessary to provide an intake port in the cabinet, and the configuration is very simple.
