Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a toaster oven, and relates to the structure of a display section that displays the set time and remaining time of a timer.

[Conventional technology]

In a conventional toaster oven, as shown in FIG. 6, a display panel 3 with a vertically long display window 2 opened in the center is arranged on one side of the front of the toaster main body 1. On the edges, for example, a scale 4 corresponding to low heat on the left edge and high heat on the right edge was displayed. A transparent plate 5 is disposed from the inside of the display window 2 of the display panel 3, and a timer (not shown) arranged behind the transparent plate 5 on one side of the toaster main body 1 operates in conjunction with a timer (not shown). A pointer band 6 that moves forward and backward is slidably arranged along the transparent plate 5, and the pointer band 6 can be moved up and down by rotating the timer setting section using a timer knob 7 provided on the side of the toaster body 1. The timer was set by sliding the tip of the pointer band 6 to match the scale 4 displayed on both edges of the display window 2.

In a conventional toaster oven, the tip of the pointer band 6 is aligned with the scale 4 on both edges of the display window 2, and the pointer band 6 located behind the display panel 3 surface through the transparent plate 5 is aligned, so the pointer band 6 is positioned apart from the scale 4 on both sides of the display window 2. It is difficult to align the pointer band 6 with the scale 4, which makes it difficult to set the timer, and the set position is likely to shift.Furthermore, the scale display is limited to both edges of the display window 2, making it difficult to display a wide variety of indications. Ta.

Therefore, it is conceivable to attach a pointer to the tip of the pointer band that can be moved between the transparent plate and the display board on which the scale is displayed, but the connection between the pointer and the pointer band is The connection work is easy if the structure is simple, such as holding the
The pointer easily comes off from the pointer band, and if the connection is strengthened by welding, for example, the connection work becomes difficult.
Furthermore, if the direction of movement of the pointer in the sliding direction is not determined, it is conceivable that unreasonable force will be applied to the pointer band, causing it to break.

The present invention was developed in view of the above-mentioned points, and an object thereof is to provide an oven toaster in which the connection between the pointer band and the pointer is made easy and reliable, and the direction of movement of the pointer is reliably determined. That is.

[Means for solving problems]
