Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cooking appliance, and more particularly to a cooking appliance equipped with a roof-type cooking menu display device capable of displaying a wide variety of cooking menus.

In cooking appliances such as high-frequency heating devices, leaf-type cooking menu display devices are used to increase the number of cooking menus displayed and to facilitate selection and setting of cooking menus.

This leaf-type cooking menu display device has a large number of display cards on which cooking menus are written, which are swingably mounted around a rotating member, and by rotating the rotating member, the display cards are sequentially reversed and displayed. The contents of the cooking menu indicated at the position can be changed. The rotation of this rotating member is normally performed by an electric motor, but since it is necessary to sequentially reverse a large number of display cards and stop them for a predetermined period of time, an electric motor cannot accurately perform such complex movements. In addition to being able to perform multiple displays, the ability to selectively rotate a large number of display cards is required.
Furthermore, according to the leaf-type cooking menu display device, a predetermined display card is selected by operating keys on a keyboard provided on the front of the cooker, but if there are many display cards, this selection time is The problem is that it is long. If the rotational speed of the rotating member is set quickly in order to shorten the selection time, there is a problem that the display card may overrun when stopped or the impact may be large, making it difficult to stop at an accurate position. Furthermore, when a user searches for a desired cooking menu before cooking, the rotating member is rotated independently and the display cards are sequentially reversed, but if the rotation speed is too fast, it will be difficult to read the cards. If it is too slow, there is a problem that the waiting time becomes long and the cooking efficiency decreases.

The present invention has been made in consideration of these points,
It is an object of the present invention to provide a cooking device that can increase the number of display cards that can be installed in a leaf-type cooking menu display device and that can accurately select display cards.

Another object of the present invention is to provide a cooking device that can shorten the time required to select a required display card and start cooking quickly. A further object of the present invention is to provide a cooking appliance that allows a user to efficiently search for a desired cooking menu.

The present invention uses a pulse motor as a rotational drive source for a rotating member, and makes it possible to control the rotational speed of this pulse motor.

The present invention allows the pulse motor to rotate at a low speed when starting and stopping, and at a high speed in the middle, thereby shortening the time required to select a required display card and making it possible to stop at an accurate position.

Further, the present invention aims to improve the efficiency of searching for cooking menus by changing the rotational speed of the pulse motor depending on the type of display card displayed at the display position.

Embodiments of the present invention will be described below with reference to the drawings.

Figure ' is a front view of the cooking appliance according to the present invention. Cooker 1
It is equipped with a cabinet 11 in which a heater, a heater, a magnetron, etc. are arranged, a heating chamber door 12, and a keyboard 13 in which operation keys are arranged. FIG. 2 is an explanatory diagram showing the structure of the cooking device according to the present invention.

The keyboard 13 is provided with various operation keys 14 and a cooking menu display window 15. A leaf type cooking menu display device 16 is mounted on the cooking menu display window 16, and various cooking menus can be selected and displayed. The leaf-type cooking menu display device 16 includes a plurality of display cards 17 on which cooking menus are written, which are swingably mounted around a rotating member 18.
By rotating the display card 8, the display cards 17 can be sequentially reversed, and the content of the cooking menu displayed at the display position can be changed. Reference numeral 19 is a stopper that restricts the swinging of the display card 17. The rotating member 18 is rotated by a rotating shaft 20 attached to the rotating member 18.
This is done by rotationally driving the motor 22 via gears 21a and 21b.

As this motor 22, a pulse motor is used. A pulse motor drive circuit 23 that sends input pulses to the pulse motor 22 to rotate the pulse motor 22 is connected to the pulse motor 22, and a preset counter circuit 24 is connected to this pulse motor drive circuit 23.

The preset counter circuit 24 includes a pulse generation circuit 25.
, fixed storage device (read-only memory ROM) 26
Further, the pulse generation circuit 25 and the fixed storage device 26 are each connected to a system controller 27.The preset counter circuit 24 is also connected to the system controller 27.The system controller 27 is further connected to the keyboard 13. Next, the operation of this embodiment having such a configuration will be explained.

The user selects the desired cooking content by operating the operation keys 14 of the keyboard 13 arranged on the operation panel of the cooking device 10. When the user presses the operation keys 14, this signal is input to the system controller 27. Display card 17
Determine how many pieces to swing from the current position.

Based on this judgment, a predetermined number of pulses is selected from those preprogrammed in the fixed storage device 26, and the preset number of pulses is preset in the preset counter circuit 24. Pulses from the pulse generation circuit 25 are input to a pulse motor drive circuit 23, and the pulses are sent to the pulse motor 22 through this circuit 23. This causes the pulse motor 22 to rotate. On the other hand, the pulses from the pulse generation circuit 25 are counted by the preset counter circuit 24, and when the number of pulses reaches the preset number, the generation of pulses is stopped and the rotation of the pulse motor 22 is stopped. In this case, the frequency of the pulses sent to the pulse motor drive circuit 23 by the system controller 27 and pulse generation circuit 25 is set low at the start so that the pulse motor 22 rotates slowly, as shown in FIG. It is controlled so that it is gradually accelerated and raised to a high speed so that it rotates steadily at high speed, and when it approaches a predetermined stopping position, it is gradually lowered to reduce the rotational speed and then stopped at a predetermined position. In addition, when the user searches for the desired cooking menu before starting cooking,
Among the operation keys of the keyboard 13, the lock key 28 is pressed to rotate the rotating member 18 independently.

In this case, the rotation of the rotating member 18 causes the display card 1 to
7 is sequentially reversed to change the contents of the cooking menu displayed on the display window 15, but no cooking operation conditions are set for each cooker. In this embodiment, the pulse motor 2 at the time of searching for the cooking menu described above is
The rotation speed of No. 2 is changed depending on the type of display card displayed at the display position.

FIG. 4 is a diagram showing an example of the arrangement of the display cards 17 that are swingably held in the rotating part village 18, and the display cards of the three-hand master are held and classified according to the cooking function of the cooker ( For example, numbers 1 to 6 indicate a group of display cards based on the cooking function of "Microwave Strong", numbers 7 to 12 indicate a group of display cards based on the cooking function of "Microwave Giichi", and cooking is performed based on the cooking function. Cards displaying cooking menus are held within that category (for example, numbers 2 to 6 are cooking menus with the "microwave high" cooking function, numbers 8 to 12 are "cooking menus"
This is a cooking menu using the cooking function of a microwave oven). and the first number of that classification (in this example numbers 1, 7, 1
3, 19, 25'31) lists menus that can be cooked based on the cooking function (in FIG. 2, the display window 15 shows a cooking menu based on the "grill" function). (The operation keys are listed with their numbers on the left side.) In addition, the remaining display cards (in this example, the remaining three cards) list the ingredients and cooking methods (time, temperature, etc.) for each cooking menu. In this case, the interval between the pulses sent to the pulse motor 22 is such that the display cards (numbers 1, 7, 13, 19, 25, 31 in FIG. 4) listing menus that can be cooked based on the cooking function are
5, the display time of these display cards (6 cards) is increased temporarily. Further, when the other remaining display cards (3 melon girls) are oscillated and reversed, the pulse interval is relatively short, and the display time is shortened. For example, the display time (rotation stop time) of six cooking function display cards is set to 1 second, and the display time of the remaining three cooking menu display cards of the father is set to 0.3 seconds. In this way, the user can reliably read the contents listed on the cooking function display card and can easily and accurately search for the desired cooking menu. Also rotating club village 1
The time it takes for 8 to rotate once and all 3 haiku-onna cards to be displayed is 1 keisuna (1 second x 60.33 seconds x 30;
1 mother sand), the user does not have to worry about waiting until the next display card comes out, and does not get frustrated.

As described above, according to the present invention, since the leaf-type cooking menu display device is rotationally driven by a pulse mode,
You can take small steps and increase the number of cards displayed on the cooking menu.

Furthermore, the accurate stopping position of the display card can be obtained with a simple mechanism. Furthermore, the frequency of the pulses sent to the pulse motor drive circuit is set low at the start, gradually increased to increase the rotation speed of the pulse motor, and gradually lowered to reduce the rotation speed when the pulse motor approaches a predetermined stop position. Since the processing is controlled in the following manner, the speed can be increased in the middle, and the time required to select a display card can be shortened. In addition, the start and stop operations of the pulse motor are performed smoothly, and no excessive force is applied to the pulse motor, gears, rotating parts, etc., increasing the durability of the leaf-type cooking menu display device, and the display card stops. It is also possible to search for the desired cooking menu accurately and quickly.
