The rotary encoder 25 is connected to the rotation operation of the time-setting dial 6 to generate a pulse in accordance with the amount of rotation, which can be input to the control circuit 18; the control circuit 18 sets the time in accordance with the number of pulses. The turntable drive motor 26 is used for driving a turntable (not shown) provided in the heating chamber 2. The control circuit 18 is in accordance with the operating program of the memory held in the microcomputer, and controls the magnetron 19, the electric heater device 20, the liquid crystal display 12, the turntable drive motor 2 6, and the light emitting diode L 1 according to each input. ~ L 2 -8- 1227313 (6). The output of the magnetron 19 is variable. Fig. 8 is a flowchart for explaining the control circuit 18. For example, the key 7e for electromagnetic cooking is operated. First, it is wrongly judged by the step S 1 0 in which the δ and the dial 6 have entered the black tone time. When the start key 5 is operated (display control is performed in step S 2 0. As shown in FIG. 6, This display g), (b), (c), (d), (e), (f),) order the controller to switch the display pattern. Each display time is the first 1 of the set cooking time. / 6 seconds, and in the next 1/6 time zone is 0.5 seconds, and in the / 6 time zone in turn become 0.4 seconds, 0.3 seconds, and 0.2 seconds. In Fig. 8, the control between step S120 and the wheat is omitted. That is, firstly, only the light-emitting diodes L1, L 2 S 3 0 are turned on, and the lighting state (that is, the display pattern state switching time T s is set to 0 · 6 seconds (step s 4 0). The display control is then turned (step S 50). The content of the control is an indication; f The flowchart of FIG. 9 is to switch the display pattern every pattern switching time τ s (the clock). When the pattern switching time T s elapses (The current display point of step R 1 〇 is "Only L1, L2, L3 is lit", and the display pattern is only "Only L2, L3, L4 is lit" (Step R 3 〇). Hereinafter, the pattern switching time T elapses. s, then the same pattern. The display control setting at the time of display control (determined in step) is based on ^ system (a (g), (h) The switching interval of the pattern is 0.6 each 1: 2 seconds, 〇1, step s 1 3 0, the pattern under L3 (step), then spin-cooled Figure 9. Initially G · 6 seconds (Yes), then switch to R 2 〇, step by step display -9- (7) 1227313 As a result, from the display pattern state of "Only L1, L2, and L3 are lit" [Fig. 6 (a)] Repeat "Only L2, L3, and L4 are lit" [Same as Figure (b)], "Only L3, L4, and L5 points" [Same as Figure (c)], "Only L4, and L0 are lit" [Same as (D)]], "Only L5, L6, and L7 are lit "[Same as figure (e)]", "Only L6, L7, and L8 light up" [Same as figure (f)], "Only L7, L8, and L1 points" [Same as (g)], "L8, L only 1. L 2 lights up the display pattern (same as (h)) °, that is, 'switch to any one is lit and the other is off' and repeat these. By switching and repeating the display pattern, a rotating display can be obtained Shapers. Also, the control illustrations from step R50 to step R60 are omitted in the "Figure 9". The display pattern is switched between 0 and 6 seconds at the first 1/6 time zone of the cooking time. Whenever the 1/6 time zone elapses in sequence, a 0.5 second interval, a 0.4 second interval, a 0.3 second interval, a 0.3 second interval, and a 0.1 second interval are created as described above. The display pattern switcher at intervals (refer to FIG. 7). According to these embodiments, the display device 13 is arranged to surround the start key 5 and is switched to the plurality of light emitting diodes L1 Any diode of the L8 is turned on and any other diode is turned off, and the control can repeat the switching, so that the display change can be improved and an easy-to-see display can be made. In particular, a rotary display mode can be obtained. Therefore, it is easier to see the display by rotating the start key 5 around the display portion, and the display is more influential without overlooking the display. In addition, the display device 13 can be changed according to the cooking time (elapsed time of the heating operation). Because of the display pattern, it is possible to display the elapsed time of heating operation by -10- (8) 1227313 by changing the display pattern. In particular, the initial (1/6 time zone of cooking time) is to switch the display pattern every 0.6 seconds, and one rotation is 4 · 8 seconds, and the next 1/6 time zone is a rotation of 0.4 seconds, the following speeds up It is 3, 2 seconds, 2.4 seconds, 1.6 seconds, and 0.8 seconds because the rotation speed of the rotary display is increased, so it is easy to know the progress of the heating. The switching time of the display pattern may be fixed (for example, 0.5 seconds). At this time, the display pattern is switched every 0.5 seconds and the rotation display is repeatedly performed, so that the positive heating operation can be well displayed. Fig. 10 shows a second embodiment of the present invention. For example, in microwave cooking, the temperature of an object to be heated can be detected by the infrared temperature sensor 22, and the detection temperature is 40 ° C for 0.6 seconds. Time interval display pattern switching ", then exceeding 40 ° C — until it becomes 50 ° C, perform" 0.5 second time interval display pattern switching ", and above 5 (TC — until it becomes 60 ° C, perform" 0.4 second interval display pattern switching " ", More than 6 (TC ~ until 70 ° C becomes" 0.3 seconds time interval display pattern switching ", more than 70 ° C-until it becomes 80 ° C and enter" 0.2 seconds time interval is not displayed Pattern switching ", and more than 8 (TC, then" 0 · 1 second time interval display pattern switching "is performed. Thus, the detection temperature (that is, the food temperature) can be well displayed by changing the display pattern. Especially by Increasing the rotational speed of the rotation display can well display the rise in food temperature. At this time, in the oven cooking, the display pattern may be switched in accordance with a predetermined temperature rise of the detected temperature of the oven thermal resistor 21. FIG. 11 shows a third embodiment of the present invention. For example, when selecting the hot-cooking menu -11-(9) 1227313, the output of the magnetron 19 is first increased and then sequentially decreased. At this time, 'in this implementation In the example, the time interval of "display pattern switching" is changed according to the change of its output. That is, "the output pattern switching is performed in 0.6 seconds interval when the output is less than 200 W"; when it exceeds 2 0 W And "400 seconds time interval display pattern switching" is performed below 400 W; "400 seconds time interval display pattern switching" is performed when it exceeds 400w and below 60 W; "0.3 seconds interval display pattern switching" when 0 W and below 800 W; "0.2 seconds interval display pattern switching" when 800 W and below iooow At the time of OW, "0 · 1 second time interval display pattern switching" is performed. According to this embodiment, the change of the display pattern can be well displayed and changed. Figs. 12 to 16 show a fourth embodiment of the present invention. For example, in this embodiment, the following points and the The embodiment is different. That is, the operator J 1 is a person who uses both the time setting dial and the heating start key, and has a structure that can be pressed (function as a start heating key) and rotatable (function as a time setting dial). That is, the operator 31 has a configuration in which the time setting dial and the start heating key are provided on the same axis. A rotary encoder 32 having a switch is provided to the back of the operator 31. The switch has a switch. The rotary encoder 32 causes the switch to operate when the operator 31 is pressed, and causes the rotary encoder to operate when the operator 31 is rotated. The display device 13 is arranged to surround the operator 31. The flowchart shown in FIG. 14 is different from the flowchart in FIG. 8 of the first embodiment in the following parts. That is, the display of the promotion time setting is performed before the setting of the heating cooking time, that is, as shown in steps S1 to S3, while the pattern switching time is set to 0.6 seconds, the initial display pattern is set as "point only" Li, L2, L5, and L6 are turned on, and the light-emitting diodes L1, L2, L5, and L6 are each turned on (step S1). Thereafter, the promotion operation display control is performed (step S2). These control contents are shown in Fig. 15. This control content is changed from the display pattern of "Only LI, L2, L5, and L6" [Step S1, Fig. 16 (d)], and it is switched and repeated every 0.6 seconds. , L6, L7 "[Step P 3 0, Figure 16 (A)]," Only L3, L4, L7, L8 "[Step P50, Figure 16 (b)]," Only L4, L5, L8, L1 "[step P70, figure 16 (c)], the factory only lights L5, L6, L1, L2" [step P80, figure 16 (d)] to obtain a rotating display form. According to this fourth embodiment, by rotating the display, rotating the operator 3 1 can easily facilitate the operation of so-called time setting. At this time, since the percentage of inactivation time setting is different from that in the heating operation, it is easy for the user to know the display used for the setting of the promotion time or the display for the heating operation. Also, the 'operator 31' may have a configuration in which the ring time setting dial is set on the same axis around the start key, or a display means may be provided to set the dial around the time setting dial. 17 and 18 show a fifth embodiment of the present invention. Among the light-emitting diodes L1 to L8, LI, L3, L5, and L7 are used as red light emitting colors, and L2, L4, L6, and L8 are used as red light emitting colors. color. According to this embodiment, the display pattern is changed by lighting the color, so that the display can be more freely changed and the display content can be more easily known. 19 to 21 show a sixth embodiment of the present invention. In this embodiment, the light-emitting monopoles L 1 to L 8 are, for example, composed of a multi-color light-emitting diode. The light-emitting diode is composed of a red light-emitting element Lr and a green light-emitting element Lg, and is driven (light-emitting) by a driving circuit Dr, Dg including an NPN transistor as an exchange element. As shown in FIG. 20, the multi-color light emitting diode emits green light with the red light-emitting element Lr turned off and the green light-emitting element Lg as a whole, and the red light-emitting element Lr is turned off and the green light-emitting element Lg is turned on. As a whole, the light is yellow-green; when the parent light of the red light-emitting element Lr and the green light-emitting element Lg is lit as a whole, the light is yellow; when the red light-emitting element L r is turned on and the green light-emitting element Lg is turned off as a whole, the light is orange; The Lr lighting and the green light emitting element Lg are turned off to emit red as a whole. Also, as shown in FIG. 21, the first ½ time zone of the heating cooking time is green or lower. The yellow-green, yellow, orange, and red colors are sequentially changed to gradually change the light emission color (display pattern). At this time, it is ideal to combine the rotation display mode. In this embodiment, because the display pattern is changed by lighting the color, the display content is more improved and the display content is more easily known. In particular, since it changes to a warm red side at the same time, the user can easily know the progress of the heating. At this time, 'as shown in FIG. 22 as the seventh embodiment of the present invention', the light emission color may be changed according to the detected temperature of the thermal resistor 21 for the oven. The color is changed to warm > 14- (12) 1227313 and the red side of the color, so the user can easily indicate the rise in heating temperature. In addition, as shown in FIGS. 23 to 8 as the eighth embodiment of the present invention, the light emission color may be changed according to the output of the magnetron 19, and at this time, the larger the output, the display color is changed to warm. The color of red is one side, so the user can easily display the rise of the output. FIG. 24 shows a ninth embodiment of the present invention. In this embodiment, for example, a case in which continuous lighting of a red light-emitting diode can be selected for red light emission, and a case in which light is illuminated intermittently in a short period and a dark red light is produced The structure is continuous with the red display area (the area in Fig. 24), and the dark red display (area DR) can be performed. In the case of such a rotation display mode, a visual effect that the light emitting portion moves with a trail can be obtained. The present invention is not limited to the embodiments described above, and may be implemented as follows. That is, for example, a demonstration display setting means is provided for performing a demonstration display setting by pressing a plurality of keys simultaneously, and when the demonstration display setting is performed, the 'control device 18 displays the operation display device with a display pattern for demonstration display 1 3 Yes. This makes it possible to increase the degree of freedom in changing the display during the demonstration of the exhibition hall and to make the display easier to see. At this time, the display pattern may be changed according to the opening / closing of 扉 3 of the heating chamber 2, so that the display pattern is changed when 扉 3 is opened and when 扉 is closed, and the display effect as an example can be improved. (Effects of the Invention) The present invention is clear from the above description. In the heating cooker, the degree of freedom of display change can be increased, and the display can be easily seen. • 15- (13) 1227313 [Brief description of the drawings] Fig. 1 is a front view showing a start key portion of the first embodiment of the present invention.
