Abstract

PURPOSE:To make at possible to set heating time as well as output and heating methods with a single timer operation by enabling diversified high-frequency output values to be set with a timer rotated in both directions and installing a heating method display and a rotary direction arrow mark and a heating time scale display in both directions respectively, centering on an output stop point. CONSTITUTION:For example, when a timer 6 is turned in the arrow marked 9 direction from an output stop point 7 'heat up' is selected as for a heating method and heating time in conformity with the types and quantities of food is set in a scale display 10 while the food is heated by a specified high-frequency output at the same time. When the timer 6 is turned counterclockwise 'raw thawing' is selected as for the heating method and it is set in the scale display 10 in conformity with the weight of the food, the heating time is set while the food is heated by a specified high-frequency output at the same time. This construction makes it possible to set output and heating methods and heating time as well by manipulating the timer 6 at one time in either case.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high frequency heating device for performing dielectric heating by high frequency, and more particularly to the output of an operation panel.
The present invention relates to heating method setting.

[0002]

2. Description of the Related Art In recent years, microwave ovens have been equipped with heating heaters to add functions such as an oven, a grill, and a toaster, and have been made multifunctional. Although the operation has become simpler, there is also a strong demand for a single-function microwave oven mainly for "warm" and "raw thawing".

[0003]

In the microwave oven which does not have the heater heating described above, two kinds of switching buttons 21 of "warming" and "fresh thawing" for setting the output as shown in FIG. 4 are used for cooking. Therefore, the timer 20 for selecting the heating time and setting the heating time must be operated, which is complicated.

[0004]

The present invention has been made to solve the above problems, and includes a heating chamber for storing foods,
In a high-frequency heating device having a magnetron that generates a high frequency and an operation panel that is provided with a timer that sets the output time, different high-frequency output values can be set by rotating the timer clockwise and counterclockwise, and a timer on the operation panel An output stop point was provided, and a heating method display, a rotation direction arrow, and a heating time scale display were provided on each of the left and right sides of the output stop point.

The color of the output stop point may be the same as the color of the heating method display and the arrow of the rotation direction and the scale display of the heating time depending on the rotation direction of the timer.

[0006]

With the above construction, by rotating the timer to the right, "warming" is selected as the heating method, and the heating time corresponding to the type and amount of food is set on the scale display, and at the same time, heating is performed with a predetermined high frequency output. , By rotating the timer counterclockwise, "raw thawing" is selected as the heating method, and when the scale is set according to the weight of the food, the heating time is set and the heating is performed with a predetermined high frequency output. Output / heating method and heating time can be set with one timer operation.

Further, when the timer is rotated, the color of the output stop point becomes the same as the color of the heating method and the like, so that it is easy to confirm the operation.

[0008]

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

FIG. 1 is a front view of a high frequency heating apparatus showing an embodiment of the present invention. In the figure, reference numeral 1 is a heating chamber, and 2 is a food item stored in the heating chamber 1, which is heated by a high frequency wave generated from a magnetron 3. Reference numeral 4 is a door that covers the front surface of the opening of the heating chamber 1. Reference numeral 5 denotes an operation panel provided in the vicinity of the door 4, and a timer 6 for setting and controlling a heating time by high frequency is provided at a lower portion of the operation panel.

FIG. 2 is an enlarged view of the operation panel 5. In the figure, 7 is an output stop point provided on the operation panel 5 in the immediate vicinity of the timer 6. Timer 6 has output stop point 7
Output variable device 11 which is provided so as to be able to rotate from the output stop point 7 to the left and right, and which changes the output by rotating to the right and to the left.
It is connected to the. 8 is a heating method display of "warming" on the right side of the output stop point 7 and "raw thawing" on the left side. 9 is an arrow indicating the direction of rotation depending on the heating method, 10 is a scale display for setting the heating time, and the left rotation of the timer 6, that is, "raw thawing" displays the weight of the food 2 to be heated, and the heating time suitable for that weight Is set. The heating method display relating to "warming", the arrow, the display color of the scale display and the display color relating to "raw thawing" are divided into two colors.

FIG. 3 is a sectional view of the main part of the output stop point 7.
In the figure, 12 is an elliptical hole formed in the operation panel 5, and a transparent plate 13 is press-fitted into this hole 12 to form an output stop point. Reference numeral 14 denotes a collar portion of a disc-shaped timer 6 which is located on the back side of the operation panel 5, and is coated with three colors 15, 16 and 17 on the surface facing the output stop point 7.
One color 15 is a display indicating that output is stopped, and the remaining two colors 16 and 1
7 is matched with the color used for the display.

Next, the operation of this embodiment will be described.

The timer 6 is rotated according to the heating method display 8 and the arrow 9 to set the time on the scale display 10 according to the type and weight of the food 2 to be heated. In the case of "warming", the timer 6 is rotated to the right to set the time, and at the same time, the continuous heating of the normal 500 W output is started. At this time, it can be confirmed that the color of the output stop point 7 changes to the same color 16 as the display color such as "warm" and "warm" is selected. With the passage of time, the timer 6 rotates counterclockwise to the output stop point 7, heating is stopped, the output stop point 7 changes to color 15, and it can be confirmed that "warming" has ended. "Raw thawing"
In the case of, rotate the timer 6 to the left and display the weight scale 10
Set to 5 and the output variable unit 11
The intermittent heating with the output of 00 W starts the heating with the output corresponding to about 200 W. At this time, as in the case of "warm", it can be confirmed that the color of the output stop point 7 is changed to the same color 17 as the display color such as "raw thaw" and "raw thaw" is selected. With the passage of time, the timer 6 rotates to the right and when it reaches the output stop point 7, the heating stops, the output stop point 7 changes to color 15, and it can be confirmed that the "raw thawing" is completed.

[0014]

As described above, according to the present invention, in a high frequency heating apparatus having a heating chamber for storing food, a magnetron for generating a high frequency, and an operation panel provided with a timer for setting an output time, different high frequency output values are provided. The setting of can be done by rotating the timer clockwise or counterclockwise, and the timer output stop point is provided on the operation panel, and the heating method display, rotation direction arrow and heating time scale display on the left and right centering on this output stop point And the color of the output stop point is set to be the same as the color of the heating method display, the rotation direction arrow and the heating time scale display according to the rotation direction of the timer. You can set the method and heating time, and when you rotate the timer, the color display of the output stop point becomes the same as the color display of the heating method etc., so the operation is easy and you can check it. Failure of combing cooking also eliminated. Also,
Since the display space can be used widely, it is possible to enlarge the display characters and make it easier to see.
