Abstract

PURPOSE:To make it possible to actuate a steam discharger to securely correspond to various cooking modes of a cooking device generating steam and supply the cooking device to prevent dews within a cooking system. CONSTITUTION:A thermosensor 7 to detect steam giving out or extinguishing, a steam discharger 4 provided with a fan 6 and a motor 5, and a receiver 9 receiving the signal from an alarm 3b attached to the side of the rice cooker 3 are equipped in the device body 1. The thermosensor 7 detecting steam generated transmits signals to drive the motor 5 through a controller to rotate the fan 6 discharging steam forcibly. When cooking is finished and steam does not generate any more, signals are transmitted from the alarm 3b which transmits signals to the controller by the detection of the receiver 9. And after the heart in the device body 1 is completely discharged, the revolution of the fan 6 with the motor 5 is stopped.

Description

[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooking device that houses a cooking device such as a rice cooker.

0002

[Prior art] With the spread of system kitchens in recent years,
Efforts are being made to make cooking equipment built-in. Regarding devices that generate steam such as rice cookers, there are problems such as condensation of steam, humidity and temperature, etc. To solve this problem, as shown in Japanese Patent Application Laid-open No. 162920/1983, as a conventional example, The configuration was as shown in FIGS. 3 and 4.

[0003] In other words, to cook rice, first drawer 1
3 towards you (→A direction) and add rice and water to the rice cooker 14.
The liquid is placed inside the apparatus main body 11, and heating is started. Steam eventually ejects from the steam hole 16, passes through a thermal reed switch 26 provided directly above, and is guided into the steam passage 20. At this time, the thermal reed switch 2 is heated by the heat of the steam.
6 rises and reaches the operating temperature or higher, the motor 22 is turned on and the steam is forcibly discharged from the exhaust hole 21 by the rotation of the fan 23. At the same time, the timer switch 29, which has a delay circuit function, is turned on. The timer motor 30 inside also starts rotating and keeps the timer contact 31 open for a certain period of time.
Set to N state. When the heating and cooking of the rice is completed and the steaming state is reached and steam no longer comes out from the steam vent 16, the temperature of the thermal reed switch 26 decreases and even if the thermal reed switch 26 is turned off, the delay circuit function of the timer switch 29 causes the electric motor 2 to
2 continues to drive, the steam inside the device main body 11 can be sufficiently exhausted, which has the effect of preventing dew condensation.

0004

[Problem to be Solved by the Invention] In the above configuration, since the delay time of the timer switch 29 is constant,
Since the required delay time differs depending on the type of cooking and the amount of rice cooked in the rice cooker 14, it is possible to stop driving the electric motor 22 before the steam ejection has stopped, or to run it for longer than the necessary time, which may result in wasted power. There are practical problems such as worsening the indoor environment (noise etc.).

[0005]

[Means for Solving the Problems] The present invention has been made to solve the above-mentioned problems, and the present invention provides an alarm from the cooker when cooking is completed (in the case of a rice cooker, the rice is kept warm after cooking is completed). A sound is emitted, detected by the receiver, and sent to the control device.
The control device is configured to stop driving the electric motor.

[0006]

[Function] With the above configuration, the delay time according to the type of cooking and the amount of rice cooked in the rice cooker can be controlled by the control device, and the drive of the electric motor can be stopped, which satisfies the effect of preventing condensation and wastes electricity. It can also prevent environmental deterioration.

[0007]

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 and 2, taking a cooking device having a built-in rice cooker as an example. ◇1
2 is a rice cooker stand slidably fixed in the apparatus main body 1; 3 is a rice cooker that is placed on the rice cooker stand 2; and 3 is a rice cooker that discharges steam to the top surface. A notification device 3b is provided in the hole 3a and the side surface. 4 is a steam exhaust device installed at the top of the device main body 1, and is installed from the rear end of the device main body 1 to the front (→
An electric motor 5 has an exhaust passage 4a toward the A direction) and has an exhaust hole 4b on the front side thereof, and has a fan 6 at the rear end thereof.
is fixed. Reference numeral 7 denotes a heat-sensitive element, which is fixed to the steam exhaust device 4 at a position opposite to the steam hole 3a. 8 is a control device;
Reference numeral 9 designates a receiving device fixed in the device main body 1 at a position opposite to the notification device 3b, and 10 designates a switch. Although the control device 8 and the switch 10 are not shown in FIG. 1, they are both provided within the device body 1.

The operation of this embodiment having the above configuration will be explained. ◇Pull out the rice cooker stand 2 to the front (→A direction), put rice and water in the rice cooker 3, store it in the main body 1 of the rice cooker, and start heating. Steam eventually ejects from the steam hole 3a, passes through the heat-sensitive element 7 provided directly above, and is led to the exhaust passage 4a. At this time, the temperature of the heat-sensitive element 7 rises due to the heat of the steam, and when it reaches the operating temperature or higher, a signal is sent to the control device 8, and the control device 8 controls the switch 10 to be in the ON state, and the electric motor 5 is driven. As the fan 6 rotates, steam is forcibly discharged from the exhaust port 4b. When the heating and cooking is completed and the steaming state is reached, and no steam comes out from the steam hole 3a, the heat-sensitive element 7
The temperature of the rice cooker decreases and the state returns to the state before cooking, but the control device 8
continues to hold the switch 10 in the ON state, and when the rice cooker 3 completes cooking after the set predetermined steaming time has elapsed, the rice cooker 3 emits a notification sound from the notification device 3b to notify the completion of cooking. The receiving device 9 detects this sound and sends a signal to the control device 8, and the control device 8 controls the switch 10 to be in the OFF state, and after the electric motor 5 and fan 6 have sufficiently exhausted the hot air inside the device main body 1. Rotation stops to prevent condensation.

In this embodiment, the notification device 3b and the receiving device 9 exchange signals by sound, but it is also possible to transmit and receive signals by light or radio waves.

0010

[Effects of the Invention] According to the present invention, the steam exhaust device is stopped after the cooking completion signal emitted from the cooker is detected, so that any cooking mode can be reliably supported, and the dew condensation prevention effect can be satisfied. At the same time, there is no wastage of electricity, no noise in the room, or other environmental deterioration, and since the signal transmission between the device and the rice cooker is wireless, there are no problems with mechanical durability and extremely reliable cooking. It provides equipment. ◇
