Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a timer device that is used particularly in a home such as a kitchen and sets a time until a target device whose time is to be managed is started.

[0002]

[Prior art]

 Conventionally, in a timer device mounted on various home electric appliances such as an electric rice cooker and a video tape recorder, or in a single timer device, an operation unit for setting time is constituted by, for example, a numeric keypad. Alternatively, there is a configuration in which the time is set forward or backward by a certain time unit (for example, every minute).

[0003]

[Problems to be solved by the invention]

 However, in the above-described conventional timer device, in the configuration in which the time is set using the numeric keypad, ten keys need to be installed, so that the installation space is increased and the size of the electric device itself is increased. In a configuration where there is a problem and the time is set forward or backward by a fixed time unit, it is necessary to keep pressing the switch until the set time is displayed while looking at the display. There are drawbacks, such as the need to change the display, and the setting takes time.

Therefore, an object of the present invention is to provide a timer device that can easily and easily set the time with a small number of keys without providing a numeric keypad as in the related art.

[0005]

[Means for Solving the Problems]

 In the timer device according to the present invention for solving the above-mentioned problems, the time setting unit is constituted by a first key having a display of 10 minutes, a second key having a display of 1 minute, and a third key having a number display relating to seconds. It is characterized in that it is possible to display the time on the time display unit by using these keys, and by setting in units of 10 minutes, 1 minute and seconds that are easy for general users to understand, Minimize the number of key installations and simplify the setting operation.

[0008] Furthermore, in order to save power, the display can be automatically turned off, and the notification sound can be set to a sound volume according to the user's preference, thereby improving usability.

[0007]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a front view of a timer showing an embodiment of the present invention, wherein 1 is a main body case, 2 is a liquid crystal display unit for displaying the time of “minute” and “second”, and 3 is A first key for setting a time of "10 minutes" and displaying it on the liquid crystal display unit 2 is a second key 4 for setting a time of "1 minute" and displaying it on the liquid crystal display unit 2; The third key for setting the time every 30 seconds (the setting of the second is not limited to 30 seconds as in this example, but can be set to an arbitrary second, such as every 10 seconds), and is displayed on the liquid crystal display unit 2. , 6 are start / stop keys for starting or temporarily stopping the displayed time display, and 7 is a reset key for resetting the time display of the liquid crystal display unit 2.

Reference numeral 8 denotes a changeover switch for changing the size of a notification sound to be notified when each of the keys 3 to 7 is pressed or when the display becomes zero by counting down time. May be at any position on the main body case 1, but in this example, it is installed on the lateral side of the main body case 1.

FIG. 2 is a longitudinal sectional view of the timer shown in FIG. 1, and includes a liquid crystal unit 10 constituting the liquid crystal display unit 2, a button battery 11 as a power supply, a circuit board 12, and the like.

FIG. 3 is a block diagram showing the configuration of the time setting control circuit according to the present embodiment. The number of times of pressing the first key 3, the second key 4, and the third key 5 is input to the input counter 15. , 16 and 17, input from a loadable counter 19 via a binary converter 18 to a converter 20, and convert the signal in accordance with the time display form by the converter 20 to drive the liquid crystal unit 10. The data is output to the circuit, and the time set by the user is displayed on the liquid crystal display unit 2 as a display. In addition, when input signals from the start / stop key 6 and the reset key 7 are input to the loadable counter 19, the control of starting or temporarily stopping the countdown or resetting the time display is performed.

Further, the time setting control circuit is provided with a function of automatically turning off the display when the time display on the liquid crystal display unit 2 is continuously performed for a certain period of time, thereby achieving power saving. be able to.

[0013]

[Effect of the invention]

 In the present invention, as described above, the time setting of the timer can be set in units of 10 minutes, 1 minute, and seconds, which is easy for general users to understand, so that the setting operation can be simplified, and Since the number of time setting keys is three, the key installation space can be reduced.

[0014] Furthermore, the display can be turned off automatically in order to save power, and the notification sound can be set to a sound volume according to the user's preference. it can.
