Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a timer for setting the energization time of a roasting heater provided in a roasting cooker body, for example, and particularly relates to a cooking time display device that clearly shows the set time of the timer. .

When roasting foods in this type of roasting cooker, there are many types of foods, some of which can be cooked in a short time and others which require a long time. The cooking time (power-on time for the roasting heater) for each cooking menu is clearly indicated on the front panel of the roasting cooker. A timer knob of the timer is installed near the timer knob, and the timer knob is manually rotated to display the time scale and timer knob displayed around the outer circumference of the timer knob in accordance with the cooking time written on the cooking menu. I tried to match the cooking time and set the cooking time.

In such a configuration, if the cooking time is long, even if the timer knob and the time scale position slightly deviate, there will be no major change in the finished cooking, but if the cooking time is short, the time scale and timer knob position will be slightly different. The matching position must be particularly accurate. That is, if it is inaccurate, the finished state of cooking that can be completed in a short time will change significantly even with slight variations in time. Therefore, in the conventional configuration, setting for short-time cooking must be done carefully and is extremely difficult.

The present invention has been made in view of the above, and an object thereof is to provide a cooking time display device that allows easy setting of short cooking time.

In the structure of the present invention, a display window for displaying the set time for long-time cooking and a window hole for displaying the set time for short-time cooking are provided on the front panel of the cooking appliance body, and the display window has a timer. A rotating drum that rotates coaxially with the drive shaft and has a time scale displayed on its outer circumferential surface faces out, and a swinging arm with an engagement pin attached thereto is rotatably supported within the main body of the cooker. The engaging pin is moved along a guide groove carved in the side wall so that the swinging arm is driven to extend beyond the rotational distance of the rotating drum for an initial short period of time, and the swinging arm is driven to extend beyond the rotational distance of the rotating drum. The time display belt is placed at the end of the moving arm so that it is facing forward.

1 is a roasting cooker main body, which has a roasting chamber (not shown) formed therein, and has roasting heaters (not shown) stretched over its upper and lower parts, respectively, and is housed in the roasting chamber. The food to be cooked is roasted for a predetermined period of time using the roasting heater.

Reference numeral 2 denotes a door body for opening and closing the front opening of the roasting chamber, and a window glass 3 is formed in the center so that the inside of the roasting chamber can be viewed from the outside. 4 is the door body 2
A front panel arranged side by side on one side is equipped with a cooking time display device, which will be described later. The side plate 5 of the roasting cooker main body 1 is exposed with a timer knob 6 for setting a time period for energizing the roasting heater. A control room 7 is defined in the back side of the front panel 4.

Reference numeral 8 denotes a timer body disposed in the control room 7, which is held and fixed to a frame 10 fixed to the inner surface of the front panel 4 with screws 9, 9. and a timer drive shaft 1 extending from the timer main body 8.
3 is formed to protrude through the support frame 11 fixed to the side surface of the frame body 10, and the timer knob 6 is attached to this part.
The rotary drum 12 is fitted onto a rotary shaft 14 of a rotary drum 12 which is supported by a rotary shaft and which surrounds the timer main body 8. A time scale 17 is displayed on the outer peripheral surface of the rotating drum. A horizontally long display window 18 is formed in the front panel at the position where the scale is closest to the front panel 4, and the scale 17 can be read from the outside through the display window. That is, when the timer knob 6 is pinched with fingers and rotated clockwise, the roasting heater is energized, and the scale 17 appearing on the display window 18 is visually read, and the desired time scale is displayed. When the rotation occurs, the rotation operation will stop at that position. Thereafter, the timer main body 8 operates counterclockwise until the set time is reached, and the rotating drum 12 and the timer knob 6 also automatically return to rotation until the cut point at which the energization of the roasting heater is cut off. be.

In the display window 18 having such a configuration, when the timer set time is short, 6 minutes or less, it is difficult to align the scale 17 with the desired position as in the conventional case. This is mainly used when setting a timer when cooking for a long time of 6 minutes or more is required, for example.

A guide groove 22 is formed on the side wall of the rotating drum 12, and includes a concentric arc groove 19 and a straight groove 21 bent outward in the radial direction from the starting end 20 of the arc groove. are doing. The linear groove 21 is set at a position approximately 45° to the upper right when the timer main body 8 is at a stopped position, that is, at a cut point, as shown in FIG. 5A.

Reference numeral 23 denotes a swinging arm which is rotatably provided with one end supported on a support shaft 24 attached to the support frame 11, and has an inverted C-shape on the side. An engagement pin 26 is provided at the end 25 of 23.
is planted toward the side wall of the rotating drum 12, and the engaging pin is positioned so as to be slidable within the guide groove 22 formed in the side wall of the rotating drum 12.

A time display belt 28 made of a colored resin film material is fixed to the other end 27 of the swing arm 23 with an eyelet fitting 29 or the like. The time display belt is slidably supported by an arc-shaped belt guide 30 formed by bending the lower surface of the support frame 11, and its free end 31 is slid along a window hole 32 formed in the front panel 4 in the vertical direction. When the timer main body 8 is at the cut point, the free end 31 of the time display belt 28 is located at the "cut" point indicated below the window hole 32. ing. A time scale 33 is engraved on the side of the window hole 32, and a free end 31 of the time display belt 28 slides along the window hole 32.
The point where is located is the set time of the timer body 8.

Next, to explain the operation in which the time display belt 28 is exposed to the window hole 32, first, when the timer main body 8 is at the cutting point, the straight groove 2 of the guide groove 22 carved in the rotating drum as shown in FIG. The engagement pin 26 of the swing arm 23 is located at , and when the timer main body 8 is driven clockwise in this state, the linear groove 21 also moves clockwise accordingly. Therefore, the engagement pin 26 located in the linear groove also moves together, and as a result, the swing arm 23 rotates about the support shaft 24. In this case, the other end 27 of the swinging arm 23 moves clockwise at a higher speed than the rotational speed of the rotary drum 12. That is, the other end portion 27 has a larger rotation radius than the rotating drum 12, and the moving distance is expanded. Therefore, while the engagement pin 26 is in the straight groove 21, the time display belt 28 fixed to the swinging arm 23 is exposed in the window hole 32 in the form of a movement that is greater than the rotational movement distance of the rotating drum. This is what is displayed.

The time display belt 2 extends to the upper end of the window hole 32.
8 reaches the sliding position, the engaging pin 26 of the swing arm 23 escapes from the straight groove 21 and is located in the arcuate groove 19. As a result, even if the rotating drum 12 continues to rotate clockwise, the swing arm 23 does not rotate at that position, and only the rotating drum 12 rotates, and the free end 31 of the time display belt 28 is placed above the window hole 32. It remains stopped at the position. Of course, when the engagement pin 26 is positioned again in the linear groove 21 of the rotary drum 12 by automatic return, the swing arm 23 also rotates counterclockwise and returns toward the cutting point.

In such a configuration, when the timer knob 6 is rotated clockwise, the display window 18 and the window hole 32 display the following information:
The scale 17 and the time display belt 28 respectively drawn on the rotating drum 12 are exposed and displayed.

For example, if the timer setting time is a short time, such as 6 minutes or less, the cooking time is set by aligning one of the time scales 33 engraved in the window hole 32 with the free end 31 of the time display belt 28. . That is, the time display belt 2 is exposed and displayed in the window hole 32.
The moving distance of 8 is expanded by the rotation of the timer drive shaft 13, and matching with the time scale 33 is easy and extremely accurate. The automatic return state up to the cut point at which the energization of the roasting heater is cut off is faster than the rotational speed of the timer drive shaft 13, so that the lowering state of the belt can be clearly confirmed visually.

On the other hand, if the timer setting time is a long time, such as 6 minutes or more, the timer knob 6 is rotated clockwise using the scale 17 of the rotating drum 12 displayed in the scale display window 18. The cooking time is set by reading the scale 17 displayed on the scale display window 18. Of course, in the adjacent window hole 32, the time display belt 28 reaches the uppermost end when the set time is 6 minutes or more,
It remains in a dormant state without sliding or moving. Then, when the time has elapsed and less than 6 minutes have passed, the straight groove 21 of the guide groove 22 carved on the rotating drum 12
When the engaging pin 26 of the swinging arm 23 engages with the belt, the belt undergoes an enlarged sliding movement and returns toward the cutting point together with the scale 17 of the rotating drum 12.

Since the present invention has such a configuration, it is easy to set the cooking time for a long cooking time by rotating the timer while looking at the rotating drum in the display window, and it is also possible to set the time for a short cooking time. This can be easily done by rotating the timer while looking at the time display belt inside the window hole. The time display belt moves when its engaging pin is slidably engaged with the guide groove of the rotating drum, so the movement of the time display belt is smooth and does not add any unnecessary resistance, ensuring reliable operation. It is possible to set the time.
