Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to an electronic timer, in which the current time is displayed by displaying the current time while the display mode operation unit is covered by the time setting operation unit. This is intended to prevent erroneous operation of the setting operation unit.

(Problems to be solved by the conventional technology and device) An electronic timer used by connecting to an electric device such as a television, an audio device, and a kitchen device is provided with a time display unit, a time setting operation unit, etc. Especially, in the case of an electronic outlet timer, the plug blade is used by inserting it into an outlet provided on a wall surface or a pillar. However, since such outlets are often installed in the foot of a wall or the bottom of a pillar, there is a problem in that the time setting operation unit is erroneously operated and the setting time tends to go wrong. It was Therefore, it is an object of the present invention to provide an electronic timer that does not become erroneously operated when the time setting operation unit is hit by an object or the like during use while being attached to an outlet. .

(Means for Solving the Problem) The present invention has a time display unit, a power feeding unit, a plug blade insertion port, and a timing element, and the opening / closing time between the power feeding unit and the plug blade insertion port is performed by the output signal of the timing element. The electronic timer is provided with a time setting operation section 6 and a display mode operation section 8, and the operation directions of the two operation sections 6 and 8 are different from each other, so that the display mode operation section 8 is set to the time setting operation section 6. for,
The lid and the cover are arranged so as to be freely exposed, and the time setting operation unit 6 can be freely operated in the exposed state, and the current time is displayed when the mode is set by the display mode operation unit 8 in the covered state. .

(Operation) In the above configuration, the time setting operation is performed in a state where the time setting operation unit 6 is exposed from the display mode operation unit 8. In addition, by covering the time setting operation unit 6 with the display mode operation unit 8, mode setting is performed, and the current time is displayed in that state. Therefore, during use, the display mode operation unit 8 is covered by the time setting operation unit 6, so that the time setting operation unit 6 is not erroneously operated and the set time is not changed.

O
There is an AUTO for performing N and OFF, and switching of these is performed by the relay conversion operation unit 8 for switching the output form of the timing element 14.

The operating portion 8 is formed of a transparent material which is transparent, and is partially cut out in a fan shape to form an opening 8a. When the operating portion 8 is rotated with a fingertip, the operating portion 6 is formed. Is exposed from the opening 8a, and the operating portion 8 is covered and hidden by this. Therefore, with the operation portion 6a exposed from the opening 8a, the display portion 3
It is possible to operate the timer setting while watching. Reference numeral 8b denotes a fingertip non-slip concavo-convex portion formed on the peripheral surface of the operation portion 8.

2a is a ground terminal 11 which is recessed in the upper back surface of the main body 2.
2b are projections provided on the lower surface of the back surface, and the projections 2a connect the power supply section 5 to the wall outlet 12
It contacts the wall surface when it is inserted into.

FIG. 4 is an electric circuit diagram, 13 is a transformer section, 14
Is a timer element, 15 is a relay unit, 3, 5, 6, and 8 are the display unit, the power supply unit, the operation unit, and the relay conversion operation unit, respectively. This electric circuit diagram is a block diagram schematically showing a known electric circuit of the electronic timer, except for the display mode operation unit 8.

The electronic timer 1 has the above-described configuration, and when setting a desired time, the operation portion 8 is rotated to open the opening 8 thereof.
After exposing the operating portion 6 from a (see FIG. 3 (a)) and operating the operating portion 6 in that state, the operating portion 8 is moved to AUTO.
Set to the (Fig. 3 (d)) side. Of course, this operation unit 8
When the timer is not used, the relay unit 15 is always ON ((b) in the figure) and always OFF according to the intention of the user.
It can be used by switching to ((c) in the figure). In any case, with the operation unit 8 set to a predetermined relay set, the operation unit 8 is covered with the operation unit 6 and the operation unit 6 is It is hidden by the operation unit 8, and the time display unit 3 displays the current time in that state.

As described above, in the electronic timer 1, the time setting operation unit 6 is hidden by the display mode operation unit 8 while the mode is set by the display mode operation unit 8 and the current time is displayed. It is possible to prevent an erroneous operation such as an object hitting the setting unit 6. Further, since the time display portion 3 is provided on the inclined surface 2a formed on the upper front side shoulder portion of the main body portion 2, even when the electronic timer 1 is mounted on a wall or a lower portion of a pillar, the time display portion 3 can be mounted from above. It has the advantage of being easy to see.

(Other Embodiments) FIGS. 5 and 6 show another embodiment of the present invention in which the front and rear shoulders of the main body portion 22 of the present electronic timer 21 are inclined surfaces 22a and 22b. , Front inclined surface 22a
