Description

[Detailed Description of the Invention] This invention relates to a cooking time display device for a cooking device such as an oven.

Generally, various types of cooking appliances are provided with a timer mechanism so that the cooking time can be set freely, and an instruction display means for displaying the cooking time. However, when looking at conventional timer mechanisms and instruction display mechanisms, for example, the timer is attached to the outer cover of the cooker via other parts, which requires a large number of parts and assembly man-hours, and is disadvantageous in terms of space. Moreover, the cooking time instructions tend to be incorrect.

This idea was devised in view of these points, and allows the timer to be attached to the side wall of the outer cover without intervening other parts, reducing the number of parts and assembly man-hours, and reducing the space required. It is an object of the present invention to provide a cooking time display device for a cooking appliance that can improve the accuracy of cooking time indication.

This idea fixes the time display drive body and time adjustment knob to the timer main shaft, and fixes the timer directly to the side wall of the outer cover of the cooker, reducing the number of parts and assembly steps for the timer mechanism and display mechanism, and reducing the space required. In addition, the bendable time indicator fixed to the time display driver moves integrally with the time adjustment knob to indicate the cooking time on the display, so it can also be used to indicate the cooking time. It is constructed in such a way that no deviations occur.

An embodiment of this invention will be described based on the drawings. First, a cooking device 1 such as an oven has a cooking chamber 3 surrounded by an outer cover side wall 4, which is closed by a door 2 that can be opened and closed. A square window 5 for display is formed on the right front side of the cooking device 1. A timer 6 is provided inside the corner window 5. The timer 6 has a built-in mainspring wound by rotating the timer main shaft 7 to set the time, and a mounting plate 8 is fixed to the projecting side of the timer main shaft 7. Two mounting holes 9 and 10 are formed in the mounting plate 8 and are positioned diagonally with respect to the timer main shaft 7 . Further, a pin 11 is fixed to the timer main shaft 7. Next, a cylindrical time display driver 12 with one end open is provided which is overlapped so as to surround the timer 6. Two half-doughnut-shaped notches 14 are formed in the bottom part 13 of the time display driver 12, and in the center of the remaining bottom part 13 is an irregularly shaped shaft 16 having a shaft hole 15 into which the timer main shaft 7 is inserted. It extends in the same direction as the protruding direction of the timer main shaft 7. Then, the shaft hole 1
5 has a recess 17 in which the pin 11 is locked in order to fix it in the rotational direction with respect to the timer main shaft 7.
is formed. Further, the time display driver 1
One end of a plate-shaped time indicator 18 that can be bent to a predetermined length is fixed to the circumferential surface of 2 with a screw 19. The other end of this time indicator 18 is an indicator 20. Such a timer 6 and time indicator 1
The timer main shaft 7 and the shaft hole 15 are fixed to each other in a stacked state, and the irregularly shaped shaft 6 is rotatably inserted into the hole 21 formed in the side wall 4 of the outer cover. are two mounting screws 22, 23
It is fixed to the jacket side wall 4 by. Here, the mounting screws 22 and 23 are screwed into the mounting holes 9 and 10, and a collar 24 is interposed therebetween to maintain a constant distance from the outer cover side wall 4. Furthermore, the mounting screws 22 and 23 are connected to the time display driver 12.
The notch 14 allows the hole to escape.
Further, a cooking adjustment knob 26 is provided on the outside of the outer cover side wall 4 and has an irregularly shaped hole 25 into which the irregularly shaped shaft 16 of the time display driver 12 is inserted and locked. That is, this time adjustment knob 26 is connected and fixed to the timer main shaft 7 via the irregular shaft 16, and is used to set the timer 6. Further, inside near the corner window 5, there is provided a double-structured display body 28 whose lower part extends to the vicinity of the time display driver 12 and is curved to have a gap 27 for guiding the time indicator 18. There is.
This display body 28 is fixed by inserting and bending a tongue piece 30 formed on the corner window 5 side into mounting holes 29 formed near both sides of the display body, and the corresponding part with the corner window 5 is straight. The transparent portion 32 is provided with a time scale 31.

In such a configuration, in the initial state, the positional relationship as shown in FIG. 5 is established, and the time indicator 18
The indicating unit 20 is set to indicate 0 minutes on the display 28. At this time, the mounting screws 22, 23 and the bottom part 13 of the time display driver 12 are in contact with each other in a counterclockwise direction, and the time adjustment knob 26, time display driver 12, and timer main shaft 7 are no longer rotated counterclockwise. It does not rotate and the time indication display never becomes less than 0 minutes.

When cooking, the cooking time suitable for the cooking is set by turning the time adjustment knob 26 clockwise. In other words, time adjustment knob 2
By turning the timer 6, the timer main shaft 7 is rotated clockwise via the irregularly shaped shaft 16, so that the mainspring inside the timer 6 is wound and the cooking time is set. On the other hand, in parallel with this, the time display drive body 12 is also rotated clockwise around the timer 6 by operating the time adjustment knob 26, so that the time indicator 18 fixed to the time display drive body 12 is rotated clockwise. The time indicator 18 moves upward while being guided by the shape of the gap 27 of the display 28 due to its curvature. Then, the instruction section 20 indicates the time scale 31 on the transparent section 32 of the display 28, thereby indicating the set cooking time. In this case, the time indicator 18 operates integrally with the time adjustment knob 26 and, therefore, with the timer main shaft 7, so the relationship between the rotation angle of the timer 6 and the time indicated by the time indicator 18 is fixed. Therefore, there is no discrepancy between the time and the cooking scale, and the cooking time is displayed with high accuracy.

By the way, when setting such a cooking time, the state shown in FIG. 6 is the limit. That is, the fifth
When the time adjustment knob 26 is rotated approximately 180 degrees clockwise from the state shown in the figure. Time display driver 12
The bottom part 13 of the mounting screw 2 is inserted in the opposite direction from the initial state.
2 and 23 (collar 24), and cannot rotate clockwise any further. Therefore, in the state shown in FIG.
0 indicates the longest cooking time on the display 28. After the timer is set, cooking is performed, and a return operation is performed by the operation of the timer 6, and the initial state is returned after the set cooking time.

Furthermore, this embodiment has various structural advantages. First, the timer 6 is directly fixed to the outer cover side wall 4 by the mounting screws 22 and 23 without intervening other parts, but the time display drive body 12 that is to be rotated has a notch 14 that escapes the mounting screws 22 and 23. Because it is formed and there is no hindrance to its rotation,
As a result, the number of parts for these mechanisms is reduced, and the number of assembly steps is also reduced. At the same time, since the timer 6 and the time display driver 12 are stacked one on top of the other, the space required for these mechanisms can also be reduced. Furthermore, since the time display driver 12 is cylindrical and covers the timer 6, it prevents dust from entering the timer 6 and also serves as an insulator. Furthermore, since the display body 28 is also curved in the vicinity of the time display drive body 12, the time indicator 18 moves smoothly while being guided along the curve. In this case, the time indicator 18 whose one end is fixed to the time display driver 12 is bendable, and in the transparent part 32, the gap 27 of the indicator 28
Since the linear instruction is given while being guided by, the correspondence between the instruction section 20 and the time scale 31 is accurate. In the cooking device 1, cooking names are often attached to the time scale 31, and in order to make the instruction display easier to read, it is better to have a long display part and a large interval between the scales. However, by increasing the diameter of the time display driving body 12 and increasing the length of the time indicator 18 while increasing the length of the display section, the correspondence relationship with the timer 6 can be established and this problem can be easily dealt with.

Since this invention is configured as described above, the timer can be directly fixed to the side wall of the outer cover without hindering the rotation of the time display drive body, and the number of parts and assembly man-hours required for the timer mechanism and display mechanism are reduced. Space can be reduced, and since the time indicator fixed to the time display driver is displaced integrally with the timer main shaft based on the time adjustment knob, accurate instructions can be displayed in accordance with the timer angle. Since the time indicator is bendable and displaced while being guided by the display, it is possible to provide linear instructions with a simple structure and high accuracy, and it is also possible to make the display section larger for easier viewing. It is also something that can be easily dealt with.
