[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooking device for home or business use.

[0002]

2. Description of the Related Art A microwave oven which is a high-frequency heating cooking apparatus which is one of the conventional heating cooking apparatuses of this type has a configuration as shown in FIG. A door 2 that can be opened and closed is provided on the front surface of the heating cooking device main body 1 so that food can be taken in and out of the refrigerator 3. A high-frequency generator 4 serving as a heating means is provided in the cooking apparatus main body, and an irradiation port for irradiating high-frequency waves into the inside of the refrigerator is formed in the refrigerator 3. The position of the irradiation port is not specified, and is formed on the ceiling surface, the back surface, or the side surface in the refrigerator, and there is a case where a plurality of irradiation ports are provided.

Reference numeral 5 denotes an input means for inputting heating cooking conditions and food information. When using this type of heating cooking device, it is necessary for the user to set the output and the cooking time in advance. The specific setting method differs depending on the individual cooking device.However, there is a specification in which the heating output, heating time, or a special heating pattern prepared in advance for a specific food is input in order. Many are seen. Numerical values and characters during the input operation are displayed on the information display means 6. FIG. 18 shows the information display means 6
In general, a 7-segment fluorescent display tube or the like is often used.

[0004] Reference numeral 7 denotes a control means, which is a high-frequency generator 4 which is a heating means based on the condition given by the input means 5.
Control on and off. Although not shown in FIG. 17, when a temperature sensor, a humidity sensor, or the like is mounted, the information is also taken in to control heating. The state during heating and cooking, such as time and temperature, is also displayed on the information display means 6, so that the user can judge the progress of cooking based on these displays.

[0005] A lamp 8 is usually provided on the wall surface of the interior 3 and is always lit during cooking. For this reason, it is possible to see at a glance that the inside of the cooking cabinet is being cooked and that the appliance is in operation.

[0006]

However, many conventional heating cooking apparatuses are intended for high-output and relatively short-time cooking. Therefore, when performing low-output and long-time cooking, the following method is required. It was causing inconvenience.

In other words, in cooking for a long time, once cooking is started, another work is performed, or in some cases, cooking is performed unattended at night. Therefore, the information display means and the lamp in the refrigerator are always turned on during operation. You don't have to. Therefore, the information display and the lamp in the refrigerator only consume extra energy, and have a specification that goes against modern energy saving.

Further, depending on the type of the device used for the information display means, the life of the device may be shorter than the life of the main body of the device due to long-time lighting.

[0009] The lighting of the interior lamp also serves as an indication that cooking is in progress, but during low-power, long-time cooking, the effect of heat generated by the interior lamp on food cannot be ignored. That is, the food in the portion near the lamp has a faster heating progress than the other portions, and uniform heating cannot be performed. This hinders the intended use of the device to make delicious dishes.

[0010]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is provided with both operation display means and information display means separately.

According to the present invention, only the operation display means provided on the front surface of the main body and indicating that the vehicle is in operation is constantly lit,
The information display means can be turned on and off as needed, so that unnecessary energy consumption can be suppressed, and by turning off the light when it is unnecessary, it can be used even on display devices that have a shorter service life than the device itself. Will be possible.

[0012] Even if the lamp inside the refrigerator is turned off, the operation display means can surely confirm that the vehicle is in the operating state.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is provided on a front surface of a main body,
It has both operation display means for indicating that cooking is in progress and information display means for displaying information about cooking being executed.

[0014] By separating the operation display means and the information display means, each of them can be turned on or off independently, so that an easy-to-understand display can be provided when necessary.

[0015] Further, it is provided on the front surface of the main body, and has both operation display means for turning on or off during cooking and information display means for turning on or off as necessary.

[0016] By not only turning on the operation display means during cooking but also blinking it, more information can be conveyed by using the operation display means which can only be turned on / off. become. On the other hand, by turning off the information display means except when necessary, energy saving operation can be performed.

Further, the information display means is a liquid crystal display device having a liquid crystal section and a light emitting section, and separately controls the energization of the liquid crystal section and the light emitting section.

Since the information display means using the liquid crystal includes not only the liquid crystal part but also the light emitting part, normally, a display with good visibility can be provided even in a dark place. By stopping the operation, an energy saving effect can be obtained.

Further, the information display means turns off the display according to a preset time after the start of cooking.

Then, after a predetermined time has elapsed after the start of cooking, the information display means is turned off to reduce the energy consumption and extend the useful life of the information display means.

Further, the information display means turns off the display according to a preset time after the start of cooking, and
It is turned on again according to a time set separately in advance.

After a predetermined time has elapsed after the start of cooking, the information display means is turned off to suppress energy consumption and extend the service life, but is automatically turned on again before the end of the set cooking time. This can also serve as a visual notification device for notifying that cooking is almost finished.

The operation display means changes the blinking cycle in conjunction with cooking conditions set in advance.

The operation display means changes its lighting color in conjunction with cooking conditions set in advance.

Then, the state change of the set cooking condition,
For example, by changing the blinking cycle and the lighting color of the operation display means in accordance with the elapse of the cooking time, it is possible to express the degree of elapse of the cooking time with only a simple operation display means such as an operation lamp.

Further, the operation display means is composed of a plurality of lighting portions, and the number of the lighting portions changes in conjunction with cooking conditions set in advance.

For example, by using the operation display means having a configuration in which a plurality of LED lights are arranged in a line, it is possible to link the lighting number with the cooking conditions, and to know the progress of cooking from the lighting number. It becomes possible.

[0028] The present invention further includes driving display means, information display means, and human body detection means, and the information display means turns on the information display means when the human body detection means detects a human body.

By providing a human body detecting means for judging whether or not a person is in front of the cooking device, the information display means is turned on only when there is a person in front of the appliance, and is turned off when there is no person. Energy-saving operation. By doing so, even if the user does not perform key operation or the like, the information display means is turned on just by standing in front of the device, so that almost the same convenience as when the light is always turned on can be obtained.

Further, when the human body detecting means continuously detects a human body for a predetermined time or more, the information display means turns on the display continuously for a predetermined time after the human body is no longer detected, and then turns off the light. If the time is shorter than the time, the display is turned off almost simultaneously when the human body is not detected.

When the human body detecting means continuously detects the human body for a predetermined time or more, even if the person moves and no longer detects the human body, the information is continuously displayed for a certain period of time and the user is displayed. The information display means can be prevented from flickering due to slight changes in body movement or posture. On the other hand, in the case of a short-time human body detection such as when a person just passes in front of the device, turning off the display immediately can efficiently suppress the energy consumption and extend the useful time.

Further, an infrared sensor is used as the human body detecting means. By using an infrared sensor for detecting the radiation temperature from an object as a human body detecting means, malfunctions due to the presence of an object other than the human body can be reduced.

In addition, the turning on and off of the internal lamp during cooking is controlled in conjunction with the information display means.

Since the inside lamp during cooking is necessary for observing the state of the inside of the cooking room, such as the progress of the cooking, unnecessary lighting by turning on the lamp in synchronism with the information display means showing information during cooking is possible. And the effect of the heat generated by the internal lamp on the food is minimized.

Further, a high-frequency heating device is used as a heating means. Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0084]

As is clear from the above description, according to the heating cooking device of the present invention, the following effects can be obtained.

The operation display means for indicating that cooking is being performed and the information display means for displaying information relating to cooking being performed are separately provided on the front of the main body. And display can be efficiently performed when necessary. That is, when a user is absent at night, useless display of the information display means is erased, energy saving operation is performed, and the life of the display device can be extended. Furthermore, since the interior lamp does not double as the operation display means, the interior lamp can be turned off during operation, and the influence of heat generated by the interior lamp on heating can be eliminated.

[0086] In addition to turning on and off the operation display means during cooking, more information can be conveyed by using the operation display means that can only be turned on / off, for example. .

Further, by using a liquid crystal display device for separately controlling the liquid crystal section and the light emitting section as information display means,
In addition to the advantages of the liquid crystal panel, which has a high degree of freedom in display content, normally, a light-emitting part can be displayed with good visibility by turning on the light-emitting part. The effect of extension can be obtained.

When there is no key operation after the start of cooking, the information display means is automatically turned off in accordance with a preset time, so that the minimum required display is performed and energy consumption is reduced. Further, the useful time of the information display means can be extended.

Further, if there is no key operation after the start of cooking, the information display means is automatically turned off according to a preset time, and is turned on again according to a preset time. Eliminating unnecessary indications to reduce energy consumption and extend the useful life, while automatically turning on again before the end of the set cooking time, the visual notification device also notifies the user that cooking is about to end. Can be fulfilled.

Further, by changing the blinking cycle of the operation display means in conjunction with the cooking conditions, or by changing the lighting color, the degree of elapse of the cooking time can be determined only by a simple operation display means such as an LED light. It becomes possible to express.

Further, by using the operation display means having a configuration in which a plurality of LED lights are arranged in a line, it is possible to link the lighting number with the cooking condition, and to display the progress of cooking by the lighting number. Can be.

Further, by providing a human body detecting means for judging whether or not there is a person in front of the cooking device, the information display means is turned on when there is a person in front of the appliance and turned off when there is no person. Driving can be performed automatically, and even if the user does not perform any key operation or the like, the information display means is turned on just by standing in front of the device, so that almost the same convenience as when the light is always turned on can be obtained.

When the human body detecting means continuously detects the human body for a predetermined time or more, the information display means is turned on and off for a predetermined time continuously after the human body is no longer detected, and then turned off.
