Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a timer device that generates fragrance when the operation of measuring the timer time is completed.

[0002]

2. Description of the Related Art Conventionally, a timer device having an aroma function has been known. Such a timer device is mainly installed in a toilet or a bathroom, and the timer is set arbitrarily so that the user does not stay in the bathroom or the bathroom for a long time. By generating a sound, the user is notified that the timer time has elapsed. In addition, for a person who uses the toilet or the bathroom later, the fragrance is sprayed for a certain time simultaneously with the generation of the notification sound.

As shown in FIG. 9, such a timer device includes a time setting switch 5 for arbitrarily setting a timer time, a display unit 2 for displaying the timer time, and a start unit for starting a timer operation. A switch 7 and a sound generator 3 for generating a notification sound when the timer operation ends.
The fragrance generating unit 12 injects fragrance when the timer operation is completed, and a control circuit (not shown) for controlling these components.

The time setting switch 5 is an up switch 5
a and a down switch 5b, and the timer time can be set by operating the up switch and the down switch. That is, every time the up switch 5a is pressed, the minute digit segment 2
a is added one minute at a time and displayed on the display unit, and every time the down switch 5b is pressed, the minute digit segment 2a of the display unit is subtracted one minute at a time and displayed on the display unit.

For example, as shown in FIG. 9, after the up switch is depressed five times to set the timer time to 5 minutes, when the start switch 7 is depressed, the timer operation starts, and every one second elapses. The value obtained by subtracting one second from the second digit segment 2b of the display unit 5 is displayed on the display unit.
Every time the minute elapses, a value obtained by subtracting one minute from the minute digit segment 2a of the display unit 5 is displayed on the display unit. Eventually, five minutes have elapsed since the start of the timekeeping operation, and when the minute digit 2a becomes “0 minutes” and the second digit “00 seconds” (the timekeeping operation ends), a signal is sent from the control circuit (not shown) to the sound generation unit 3. Is supplied from the sound generator 3 for a predetermined time, a drive signal is supplied from the control circuit to the fragrance generator 12 for a certain time, and the fragrance is injected from the fragrance generator 12 for a certain time. As shown in FIG. 10, the time of one injection from the fragrance generating unit 12 is:
In any case, the supply time (for example, 9 seconds) is set in advance so that the room can be sufficiently deodorized. Thus, after using the toilet or the bathroom, the interior can be deodorized with the fragrance, so that a user who uses later does not feel unpleasant.

[0006]

According to the conventional timer device, each time the timer device is used, a fragrance is injected for a certain period of time (a driving time during which the interior of the room can be sufficiently deodorized when the fragrance generating section is driven). And there is a problem that the fragrance is quickly lost. The present invention has been made in view of the above problems, and an object of the present invention is to provide a timer device that can save a fragrance by generating a necessary amount of fragrance when necessary.

[0007]

According to a first aspect of the present invention, there is provided a time setting means capable of arbitrarily setting a timer time, and a fragrance generating section for generating a fragrance. And a timer device provided with a control circuit for driving the fragrance generation unit when the timer time measurement ends, wherein the control circuit sets the time for driving the fragrance generation unit according to the timer time.

[0008] It is considered that the time when the user uses the toilet or the bathroom is substantially equal to the timer time, and the fragrance generating section is driven according to the timer time after use.
As described above, the control circuit drives the fragrance generating section based on the timer time, so that the fragrance can be efficiently used as needed, and the interior or the like can be sufficiently deodorized.

According to a second aspect of the present invention, a time setting means capable of arbitrarily setting a timer time,
In a timer device including an fragrance generating unit that generates fragrance, a preset time and a timer time that are stored in advance are compared, and if the timer time is equal to or longer than the set time, the fragrance generating unit is stopped after the timer time is measured. Is provided with a control circuit for driving for a certain period of time.

[0010] Considering that the time for the user to use the toilet or the bathroom is substantially equal to the timer time, and when the time for use is short (less than the set time), the fragrance is generated from the fragrance generating section. Instead, when the use time is long (when the time is equal to or longer than the set time), the fragrance is generated from the fragrance generating section. As described above, since the control circuit determines whether or not to generate fragrance using the set time as a threshold value, fragrance can be generated when necessary, and the interior and the like can be sufficiently deodorized.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a specific example of a timer device according to the present invention will be described with reference to FIGS. FIG. 1 is a front view showing a timer device of a first specific example, FIG. 2 is a sectional view of the timer device shown in FIG. FIG. 4 is a flowchart of the timer device of the first specific example.

As shown in FIGS. 1 and 3, a timer device 1 of a first specific example includes a display unit 2 for displaying a preset timer time, which will be described later, a time setting switch 5 for setting the timer time, and a timer. A start switch 7 for starting the time counting operation of the timer, a sounding unit 3 for generating an alarm sound when the time counting operation of the timer ends, an fragrance generating unit 12 for injecting the fragrance when the time counting operation of the timer ends, and each of these elements. And a control circuit 10 for controlling based on a flow described later.

As shown in FIG. 1, the display unit 2 has a minute digit segment 2a and a second digit segment 2b. For example, when the minute digit segment 2a indicates “5” and the second digit segment 2b indicates “00”, the timer time indicated on the display unit 2 is “5 minutes”.

The time setting switch 5 includes an up switch 5
a and a down switch 5b.
a is pressed once, the minute digit segment 2a of the display unit 2
Are added and displayed one minute at a time. Each time the down switch 5b is pressed once, the minute digit segment 2
a is subtracted by one minute and displayed. As shown in FIG. 1, the minute digit segment 2a can set a timer time from 1 minute to 9 minutes. The time setting switch 5 does not correspond to the second digit segment 2b, and cannot set the time in seconds.

The start switch 7 is a switch for starting the timer operation of the timer when pressed after setting the timer time. When the timer operation is started, the timer time (for example, 5 minutes) indicated on the display unit is decremented in units of seconds with the elapsed time by the countdown method before the start switch 7 is pressed. it's shown.

As shown in FIG. 2, the fragrance generating section 8 includes a motor main body 8a for rotating the rotating shaft 8a for a predetermined time by a driving signal of the control circuit 10, an eccentric plate 8c fixed to the tip of the rotating shaft 8a, It is composed of a spray can 8d for storing a fragrance and an injection nozzle 8e provided at the tip of the spray can 8d. As is conventionally known, the spray can 8d sprays the fragrance contained therein by pressing the spray nozzle 8e. The motor main body 8a and the spray can 8d are fixed to the frame, and when the rotating shaft 8a rotates, the eccentric plate 8c and the injection nozzle 8e engage, so that the fragrance is supplied to the outside of the frame through the through hole 12. Can be injected.

The sound generator 3 generates a notification sound for a predetermined time (for example, three seconds) in order to notify the user of the end of the timer operation by the drive signal of the control circuit 10. is there.

The operation of the timer device of the first specific example will be described with reference to FIG. First, a timer time is input by operating the time setting switch 5 (S1). When the timer time is input, the timer time is automatically stored in a memory (not shown) provided inside the control circuit 10 (S2).

When the start switch 7 is depressed after the input of the timer time is completed (S3), the operation of measuring the timer time is started in the control circuit 10 (S4).
Then, it is determined whether or not the timing operation has been completed (S
5). When the timer operation of the timer time is completed and the timer time stored in the memory is 1 minute (S6), a drive signal is supplied from the control circuit 10 to the sound generation unit 3 for a predetermined time (for example, 3 seconds), and a notification sound is generated. Generated and the control circuit 10
A drive signal is supplied to the motor main body 8a of the fragrance generating section for one second (S7).

When the timer operation of the timer time is completed and the timer time stored in the memory is 2 minutes, (S
8) A drive signal is supplied from the control circuit 10 to the sound generator 3 for a predetermined time (for example, 3 seconds) to generate a notification sound,
A drive signal is supplied from the control circuit 10 to the motor body 8a of the fragrance generating section for 2 seconds (S9).

As described above, when the timer operation of the timer time is completed and the timer time stored in the memory is N minutes, the drive signal is supplied from the control circuit 10 to the sound generator 3 for a predetermined time (for example, 3 seconds). And the alarm sounds,
A drive signal is supplied from the control circuit 10 to the motor body 8a of the fragrance generating section for N seconds.

If the relationship between the timer time (minutes) and the supply time (the time during which the drive signal is supplied to the fragrance generating section) is represented in a graph, the relationship between the timer time and the supply time is proportional as shown in FIG. The timer time and the supply time may not be in a proportional relationship as shown in FIG. For example, as shown in FIG. 6, when the timer time is in the range of 1 minute to 3 minutes, the supply time increases by 0.5 seconds every time the timer time increases by 1 minute. When the timer time is in the range of 3 to 8 minutes, the supply time is increased by 0.5 seconds every time the timer time is increased by 1 minute. Further, if the timer time is 8 minutes, the supply time is 7
In seconds, when the timer time is 9 minutes, the supply time is 9 seconds.

As described above, by driving the fragrance generating section for a time corresponding to the length of the timer time, when the user is only in the room for a short time, a small amount of fragrance is jetted, and conversely, When a person stays in the room for a long time, a large amount of fragrance is sprayed with the fragrance, whereby the fragrance can be saved, and the room can be deodorized for a person who uses it later.

Next, a second specific example will be described with reference to the flowchart shown in FIG. In a second specific example, a set time is stored in a memory provided inside the control circuit in advance in a manufacturing stage, and it is determined whether or not the timer time is equal to or longer than the stored set time. When the timer operation is completed, the fragrance generation unit 8 is not driven when the timekeeping operation is completed. This is for driving the fragrance generating section 8. Note that the front view of the timer device of the second specific example is the same as that of the first specific example shown in FIG. 1, and will be described with reference to FIGS. 1 and 7.

An example will be described in which the set time is set to 5 minutes. First, a timer time is input by operating the time setting switch 5 (S1). When the timer time is input, the timer time is automatically stored in a memory (not shown) provided inside the control circuit 10 (S
2).

When the start switch 7 is pressed after the input of the timer time is completed (S3), the timer time and the set time are compared in the control circuit 10 (S3).
4) When the timer time is shorter than the set time (3 minutes), when the timekeeping operation (S5) ends (S6), the drive signal is sent from the control circuit 10 to the sound generator 3 for a predetermined time (for example, 3 minutes).
(A second), the notification sound is generated, but the drive signal is not supplied from the control circuit 10 to the fragrance generating section 8 (S7).
Conversely, if the timer time is longer than the set time (5 minutes),
When the timing operation (S8) ends (S9), the drive signal is sent from the control circuit 10 to the sound generator 3 for a predetermined time (for example, 5 minutes).
Along with the supply, a notification sound is generated, and at the same time, a drive signal is supplied from the control circuit 10 to the fragrance generating section 8 for a predetermined time, and the fragrance is injected from the fragrance generating section 8 (S10).

FIG. 8 is a graph showing the relationship between the timer time (minutes) and the supply time (the time during which the drive signal is supplied to the fragrance generating section). As shown in FIG. When the driving signal is not supplied to the fragrance generating unit after the time counting operation is completed and the timer time is 5 minutes or longer, the time period after the time counting operation is completed and the fragrance generating unit 8 can sufficiently deodorize the room or the like ( The drive signal is supplied for only 9 seconds, for example.
Therefore, also in the second specific example, as in the first specific example, it becomes possible to generate the fragrance as needed and to use the fragrance efficiently.

In the above specific example, the set time and the timer time are set by the time setting switch 5. However, the present invention is not limited to this. For example, a microphone may be used instead of the time setting switch 5 and the timer time may be set by a user's voice. May be input to the timer device 1.

In the above specific example, the fragrance generating section 8 sprays the fragrance by pressing the injection nozzle 8e with the eccentric plate 8c using the spray can 8d containing the fragrance. However, the invention is not limited to this. For example, a heat source is provided in a timer device,
When the timer operation of the timer time is completed, the fragrance may be heated to evaporate to the outside by applying heat.
