Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a microwave oven capable of preventing the next heating operation from starting for a certain period of time after the completion of heating.

[0002]

2. Description of the Related Art In recent years, the aging of society has accelerated, and according to published information, the percentage of elderly people aged 65 and over in Japan will reach over 25% by 2020. It is predicted that. At present, the number of elderly households living alone is rapidly increasing, coupled with the effects of the nuclear family.

[0003] By the way, in the household only for the elderly,
It is said that complicated cooking is often avoided, and it is said that there is a strong tendency to eat a simple meal simply by reheating cooked instant food.

[0004] However, while continuing to consume such foods,
It is not easy for elderly people with weakness and weakness to maintain nutritional balance.

[0005] Under such a social background, a business of providing lunch by home delivery is growing. This is because a food service provider (delivery company) delivers a tray containing food for one meal (for example, rice, side dishes, miso soup, etc.) in consideration of nutritional balance to the client's home at the time of meal, and delivers it to the recipient. By reheating with a microwave oven on the side, it was possible to eat a warm meal.

[0006]

SUMMARY OF THE INVENTION The present invention relates to the fact that a person who receives a lunch service can carry a tray by himself, can be stored in and taken out of a microwave oven, and starts heating the microwave oven. It is assumed that operation is possible as the minimum qualification of the user.

[0007] Further, regarding the microwave oven, it is set as minimum requirements that the operation panel is as simple as possible and that complicated operations are not required.

[0008] However, there is no user who once again or repeatedly performs the heating start operation even though the food placed in the microwave oven has already been heated. Not exclusively. In that case, there is a problem that even if the precious food is rendered inedible, or if it does not, the temperature of the food is abnormally increased, thereby increasing the risk of burns when taking out the food. In addition, the same applies to the danger of so-called empty baking, in which a heating operation is performed without installing food in the heating chamber.

The present invention has been made in order to provide a microwave oven in which such a problem is solved, and not only for the elderly but also for those who have to rely on a lunch service due to a handicap. But it must be effective.

[0010]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention prohibits the start of the next heating operation for a certain period of time after the end of heating, or enables the heating operation to be repeated without prohibition. Can be selected and set by the selection setting switch.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is configured as described above, and on the other hand, only for a certain time after the end of heating,
Avoid repeated heating, so that the food does not become inedible, and if it does not, the temperature of the food does not rise abnormally, while if the food is taken out, it is baked. Was not started. On the other hand, the heating operation can be repeated, and the microwave oven function can be used without any particular restriction. That is, both functions can be selectively used.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the microwave oven of the present invention will be described below with reference to FIG.

FIG. 1 is a front external view, wherein 1 is a main body of a microwave oven, 2 is a door for opening and closing an opening of a heating chamber, 3
Denotes an operation panel.

Reference numeral 4 denotes a display for displaying the elapse of the heating time.
Reference numeral 5 denotes a start button for starting a heating operation, and reference numeral 6 denotes a light-emitting unit which blinks when the heating is completed to notify the end thereof. In this embodiment, the start button 5
Is operated, the heating output and the heating time are fixed constant values such as 400 watts / hour and 10 minutes, respectively.

Reference numeral 7 denotes a blind cover which can be removed by using a special tool, and is usually attached in a state where it cannot be easily removed.

Reference numerals 8 and 9 denote operation number setting buttons provided in a state of being hidden by the blind cover 7.
8 is a button for setting one operation, and 9 is a button for enabling two operations. The reason why the two operations can be set is that the application range of the microwave oven of the present invention is not limited to the heating of one meal.

10 to 12 are the operation number setting buttons 8
Is a button for setting an operation inhibition time after the end of the heating operation, 10 is a button for setting the inhibition time to 4 hours, 11 is a button for setting it to 6 hours, and 12 is a button for setting it to 0 hour. is there.

Since the microwave oven of this embodiment is a dedicated device for heating a predetermined food to a predetermined state, the heating output and the heating time do not need to be adjusted. It is needless to say that setting the adjustment buttons and the like inside the blind cover 7 in order to increase the image quality is extremely useful.

In the microwave oven having such a configuration, the supplier of the microwave oven removes the blind cover 7 and operates the operation number setting button 8 or 9 by operating the operation number setting button 8 or 9 specified by the delivery destination user. Set once or twice. At the same time, the operation prohibition time after one or two operations are executed is set to the operation prohibition time setting buttons 10 (4 hours), 11 based on the user's request.
(6 hours) and 12 (0 hours). It should be noted that setting the operation prohibition time setting button 12 (0 hour) does not substantially prohibit the repetitive operation. Therefore, it is necessary to carefully set the setting based on the ability of the user. is there.

Although not described in detail, in this embodiment, the buttons under the cover 7 are not easily removed so that incorrect setting by an unskilled person does not occur. In addition to the above, for example, the operation prohibition time setting buttons 10, 11,
While all of 12 are pressed, the number of operations
When the button 9 is pressed, the number of operations of the pressed button is set for the first time. On the other hand, while both of the buttons 8 and 9 are pressed, the operation inhibition time setting buttons 10 and 1 are set.
When any one of the buttons 1 and 12 is pressed, the operation inhibition time corresponding to the pressed button is set for the first time.

The actual setting operation is performed before shipment or at the delivery destination in accordance with a user's request.

At the user's home where the microwave oven is installed,
When a set of meals (not shown) placed on the tray is distributed, the user opens the door 2 of the microwave oven and places the set of trays in the heating room. Then, the user presses the start button 5 to start the heating operation.

When the heating is completed, the light emitting section 6 blinks a predetermined number of times to notify that the food in the tray set is in the edible state. Therefore, the user opens the door 2, takes out the set of trays, and starts eating.

The number of operable times set in the microwave oven is 1
Times and the operation prohibition time is 4 hours.
The microwave oven cannot be started over time. If the meal intake time is, for example, 7:00 am for breakfast, noon for lunch, and 7:00 pm for dinner, the time for lunch and dinner should be the time after the breakfast time and after the operation prohibited time from the lunch time sufficiently. Therefore, the microwave oven can be fully utilized when necessary, and unnecessary and dangerous operation can be completely prevented.

In this microwave oven, the operation prohibition time can be made zero in response to the operation of the button 12 inside the blindfold cover 7, that is, the heating operation can be continuously repeated. If it is known that a dedicated operator etc. will surely handle the food, it will be possible to heat multiple meals continuously, even if it is one meal at a time.

[0026]

As described above, according to the present invention, the operation of the microwave oven can be prohibited for a certain period of time after the heating is completed. Dangerous heating is no longer performed.

[0027] In addition, by switching the switch, heating can be performed continuously and repeatedly, so that the present microwave oven can be effectively used even when heating a plurality of fixed-sized meals.
