Abstract

PURPOSE:To efface impression in which omitted cooking is performed with the use of a microwave oven without a sound, which is sounded chin, informing cooking completion by having a means for selecting a plurality of cooking completion information means and these information means. CONSTITUTION:Keys such as 'hot insulation and start', 'speech synthesis', 'electronic sound', 'illumination', 'order', 'remote control', and 'silent' in addition to keys such as 'warm and start', 'toast', and 'uncooked foods thawing' are provided on an operation instruction input keyboard. When for instance, the key indicated as 'illumination' of these keys is pushed, the switch of an illuminating light light 7 is turned on by the signal from a timer at the time of the completion of cooking to put on the illuminating lamp 7 of a microwave oven 10 so as to inform a cook of the completion of cooking. In addition, a speech synthesis key and an electronic sound key are pushed in place of an illumination key, voices and electronic music for informing cooking completion respectively at the time of the cooking completion can be heared.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a microwave oven.

[Prior Art and Problems to be Solved by the Invention] Microwave ovens have conventionally been used to defrost frozen foods and reheat cold dishes.

However, this type of microwave oven is configured to emit an electronic beep sound at the time of initial setting and a chirp sound at the end of cooking. This gives diners the impression that they are being fed shoddy food cooked in a microwave.
Decreases appetite.

The present invention has been developed in view of the drawbacks of conventional microwave ovens, and the present invention has been developed in view of the drawbacks of conventional microwave ovens. A microwave oven that meets the needs of housewives who do not want to give the impression that they are cutting corners with the microwave, and also meets the needs of restaurant operators who do not want to give the impression that they are serving frozen foods to their customers. The purpose is to provide

[Means for Solving the Problems] The microwave oven of the present invention is characterized by having a plurality of cooking end notification means and means for selecting the notification means.

[Example] Hereinafter, a microwave oven of the present invention will be described based on the drawings, but the present invention is not limited to such examples.

FIG. 1 is a schematic diagram of the microwave oven of the present invention, FIG. 2 is a functional block diagram of the microwave oven shown in FIG. 1, and FIG. 3 is a block diagram showing the electrical configuration of the microwave oven shown in FIG. FIG. 4 is an arrangement diagram of an embodiment of a keyboard for inputting operating instructions, and FIG. 5 is a flowchart of an embodiment of cooking using a microwave oven of the present invention.

In Figure 1, (1) is a microwave oven, (2) is a control device, (3) is a power supply circuit, (4) is a cooling fan, (5) is a

is in 1ili, 01) is food for cooking.

As shown in Figure 2, the control device (2) includes a cooking sensor, a manual keyboard for operating instructions, a display device, a heat retention device, a magnetron (5), a cooling fan (4), a starter fan (6), and a turntable (8). ), voice synthesizer, electronic sound generator, lighting device, odor generator, and remote control device. The control device (2) consists of a processing unit (CPLI) and a memory, as shown in FIG.

The CPU operates the cooling fan (4), magnetron (
5), drives the starter fan (6), turntable (8), etc. Since these prefectural processing operations are no different from those of conventional microwave ovens, detailed explanation thereof will be omitted.

As shown in FIG. 4, the keyboard for inputting operation instructions of the present invention includes conventional keys such as "warm/start", "toast", "thaw perishables", etc., as well as "keep warm/start", "Speech synthesis", "electronic sound", "lighting",
Keys such as "smell", "remote control", and "siren I" are provided. These added key functions are the fifth
Flowchart 1 shown in FIG.

The door (9) is opened and the food to be cooked is placed on the turntable. Close the door (9), press the lighting key, set the timer, and press the warm/start key. Just like a conventional microwave oven, the start fan, cooling fan, turntable, and magnetron are activated to start cooking.

When the predetermined interval has elapsed and cooking is completed, the illumination light (7) is turned on by a signal from the timer, and the illumination light (7) in the refrigerator interior 00 is turned on to notify the cook that the cooking has ended. When the food is taken out, the lighting lamp (sword) is turned off and the cooking process is completed.The circuit for lighting the lighting lamp (sword) can be any circuit that has traditionally been used for this type of thing. Not limited.

Instead of the lighting key, if you press the voice synthesis key or the electronic sound key, a voice or electronic music will be played to notify you when the cooking is finished, respectively. As a device for playing audio, electronic music, etc., conventionally known devices such as a tape recorder, an electronic musical instrument, a synthesizer, etc. into which specific audio is recorded can be suitably used. Instead of playing electronic music or the like at the end of cooking, the program may be changed to play electronic music or the like during cooking and stop the music at the end of cooking. In this way, it is possible to reduce the noise generated from cooling fans, magnetrons, etc. during processing.

When you press the odor key, the odor corresponding to the cooked product will be emitted when cooking is complete. For example, when aromatic hydrocarbons are heated by a heater or vaporized by a blower fan, the odor may be artificially emitted from a microwave oven. occurs to notify the end of cooking.

When the remote control key is pressed, the microwave oven generates a wireless signal when cooking is complete, which lights up or flashes a sign light installed elsewhere in the room to notify the cook that cooking is complete. The remote control device to be used is not particularly limited and can be any device conventionally used for remote control of rice, such as ultrasonic and infrared sensors.

If you press the silent key, no display will be displayed when cooking is complete. In this case, there is a risk of forgetting to take out the food, but if the Keep Warm/Start key is pressed and the Keep Warm mode is selected, the Keep Warm device will activate if the food is not taken out within a certain period of time after cooking is finished. Finished items are kept warm. The heat-retaining device is not particularly limited and can be any device conventionally used for this type of heat-retaining device.

The method of notifying the end of cooking based on the keys on the keyboard for inputting operating instructions has been explained above, but the method of notifying is not limited to the above, but can include an indicator lamp on the operation panel that flashes the light inside the refrigerator 00, etc. It is also possible to adopt methods such as changing the brightness of a light emitting diode or the like, or changing the color of the lighting inside the refrigerator (10).

[Effects of the Invention] As explained above, the microwave oven of the present invention can eliminate the "ding" sound that signals the end of cooking, and can eliminate the impression that the microwave oven is cooking without any care. At the same time, it has the effect of introducing playfulness into cooking and making cooking fun.
