Description

[Detailed description of the invention] (a) Industrial application field This invention relates to, for example, a timer that sets the energization time of a roasting heater provided in the roasting cooker body.

(B) Prior Art Currently, there are cookers that have enlarged scales in the cooking time display window to make it easier to set the frequently used time range, but this type of cooker has separate enlarged scales and normal scales. As a result, more parts are required, resulting in higher costs.

Furthermore, when cooking for a short time, it is necessary to set the cooking time more accurately than when cooking for a long time, and the only type of cooking that meets this need is one that has separate enlarged scales and normal scales.

(c) Purpose of the invention This invention was made in view of the above points, and aims to provide a cooking time display device that has a single display window and displays scales at large intervals during a necessary predetermined period. It is something.

(d) Structure of the device This device has a display window on the front panel of the cooker that displays large scale intervals at predetermined intervals during all set cooking times, and a timer inside the cooker that is coaxial with the drive shaft of the timer. A rotating lever is provided with a rotating drum that rotates as the rotating drum rotates, and a rotating lever that is appropriately pivoted and has a time display belt attached to its end that faces the display window. The cooking time display device is provided with a guide mechanism that changes the rotation angle of the rotary lever and thereby moves the time display belt at high speed in accordance with the large scale interval of the display window.

(E) Examples Examples of this invention will be described in detail below with reference to the drawings, but this invention is not limited to the following examples.

FIG. 1 shows an oven 1 in which the cooking time display device of this invention is used, and a display window 4 having a scale 3 is provided on its front panel 2 in a vertical direction. Scale 3 is displayed at large intervals during the initial period from about 1 to 10 minutes. A timer and the like are provided below the back of the front panel 2 of the oven 1, and 5 is an operating end of the timer that rotates in conjunction with the timer.

2 to 5 each show an enlarged configuration of the cooking time display device.

A rotary drum 8 is fitted onto a drive shaft 7 of the timer 6, and as the drive shaft 7 of the timer 6 rotates, the rotary drum 8 is rotated.
The timer 6 is connected to the board 10 via the timer mounting plate 9.
mounted on. On the other hand, a rotary lever 11 is attached to the base plate 10 so as to be rotatable about a support shaft 12. A guide pin 13 is attached to the rotary lever 11, and a time display belt 14 is fixed to the end with an eyelet 15. are doing. 18 is the time display belt 14
It is a guide body. In this state, if the guide pin 13 of the rotary lever 11 is fitted into the guide groove 16, which is the guide mechanism of the rotary drum 8, when the timer is "off", the rotary drum 8, the rotary lever 1
1. The time display belts 14 are positioned in relation to each other as shown in FIG. From this state, when the timer 6 is fully wound in the direction of the arrow, the state shown in FIG. 4 is obtained. The reason for this is that the guide groove 16 has a path as shown in FIG. On the other hand, the distance from the center O to the guide pin 13 of the rotary lever 11 also changes when the rotary lever 11 is rotated around the point Q, so when the rotary drum 8 is rotated, x=
This is because the rotary lever 11 rotates until it reaches OP, and the time display belt 14 moves within the case 17 located at the back of the display window 4.

Here, if the rate of change of x at the winding angle of timer 6 corresponding to the initial cooking time (10 minutes), that is, the slope of the change in x, is made steep, and thereafter the slope of change in x is made gentler. , the rotation lever 11 is operated at high speed during the initial period, and thereafter at low speed (guide groove 1
The path 6 allows the speed to be reduced rapidly or gradually. ), and a scale 3 is displayed on the front panel 2 in accordance with the movement of the time display belt 14.

In the above embodiment, the scale is displayed at large intervals during the initial period of the total set cooking time, and the time display belt moves at high speed in that portion.
If the time period of 10 to 15 minutes is used very often, the scale may be displayed at large intervals during that period, and the time display belt may move at high speed during that period. In this case, the guide groove may be shaped so that the above-described gradient of change in x becomes steeper in accordance with the period.

(f) Effects of the invention This invention is constructed as described above, and since the necessary scale is formed in one display window and is large, the display is easy to see and the construction is simple. It has the advantage of being easy to manufacture and having fewer failures. In particular, by using a time display belt facing the scale display window to indicate the scale, it is possible to indicate the scale by dividing it into two parts, the part covered by the belt and the part not covered. Since specific instructions can be given by the line at the tip of the belt, the scale can be made more accurate and easier to see, and the intention of making the scale larger can be more effectively utilized.
