Description

[Detailed description of the invention] This invention is a sleep timer or a timer that turns on electricity after a certain period of time (for example, a timer used to automatically operate a rice cooker).
This invention relates to a timer that allows the user to select an operation from "on" to "off" or from "off" to "on" and set the time until the operation is performed.

Conventional timers of this type that are equipped with a selection section from "on" to "off" or from "off" to "on" and a time setting section can perform the desired operation only by operating two places. can be obtained.
Therefore, those in the lower grades of elementary school, women, and others who are weak against machines tend to think that the desired action will be performed by simply manipulating one part, and when the action is actually performed, they may not understand that it is the action that they wanted. The results were often completely different. For example, I had set the rice cooker so that I could eat hot rice as soon as I woke up in the morning, but the setting happened to be from ``on'' to ``off'', so the rice ended up cooking while I was sleeping at night. ,
Sometimes the result was that it was already cold when I woke up in the morning.

Therefore, the purpose of the present invention is of course to enable two ways of usage: turning the power to an electrical device from "off" to "on" or from "on" to "off" when a desired time has elapsed. In either case, it is possible to switch from "off" to "on" or from "on" to "off" with a single operation of turning a single spindle.
The selection and time setting can be done at the same time, making it possible to prevent the occurrence of mistakes as in the case of the conventional products mentioned above. It is an object of the present invention to provide a timer with an indication of "on".

The drawings showing the embodiments of the present application will be described below. 1 is a case, 2 is a main shaft rotatable with respect to the case 1, 3 is a fast-acting cam fixed to the main shaft 2, and 4 and 5 are fast-acting cams fixed to the main shaft 2 on both sides sandwiching the fast-acting cam 3. The first and second contact cams and 6 are main levers, which are pivotally connected to the case 1 via a pivot shaft 7 and driven by the cam 3. Reference numeral 8 denotes a spring that presses the tip 6a of the main lever 6 against the cam 3. Reference numerals 9 and 10 denote first and second driven levers whose respective bases are pivotally connected to the lever 6, and are driven by the first and second contact cams 4 and 5, respectively. Reference numerals 11 and 12 denote first and second switches, which are driven by first and second driven levers 9 and 10, respectively. Next, reference numeral 13 denotes the first gear loosely fitted onto the main shaft 2, which is connected to the main shaft 2 via a known friction mechanism consisting of a friction plate 14, a spring seat 15, etc., and the rotation of the first gear 13 is caused by the main shaft 2. However, the rotation of the main shaft 2 that is manually operated is the first gear 13.
It has become difficult to convey this to others. 16 is a motor pinion of the timer motor TM, and 17 is a gear train, which decelerates the rotation of the motor pinion 16 and connects it to the first gear 13.
It is designed to convey information to the public. Note that 18 is a cover that is attached to the case 1 to cover the various mechanisms described above. Next, 19 is the time display surface, and this display surface includes timer case 1 and cover 18.
Alternatively, any location such as the panel surface of the machine in which this timer is used may be selected. In this display surface 19, 20 and 21 indicate "on" to "off" and "off" to "on" arranged so as to divide the display surface into two, and 22 indicates a section of "on" display in the display 20. The time scale 23 is a time scale written in the section of the display 21 where "off" is displayed. In this example, scales are also attached to the position of the "OFF" display on the display 20 and the "ON" display position of the display 21, respectively, for the purpose of unifying the design of the time display surface. In addition to the "hour" scale as in this example, any other scale such as a "minute" scale may be used as these scales. Furthermore, the 5 minutes of the display surface 19 may be set to any desired ratio. 24 is a "continuous" display written on one of the boundaries of both the above-mentioned displays 20 and 21. In addition to the circular display as in this example, these displays may be linear and horizontally elongated. Next, 25 is a pointer fixed to the main shaft 2, which includes the above-mentioned displays 20, 21, 24 and time scales 22, 2.
3 is shown.

Next, the above timer motor TM and switch 1
1 and 12 are connected as shown in FIG. 3, and the relationship between the indicated position of the pointer 25 and the opening and closing of the switches 11 and 12 is as shown in FIG. still
PL is an indicator light that indicates that the timer is set to an operating state. 26 is a resistance. Further, 27 is an input terminal, and a plug for a power line is generally used. Reference numeral 28 denotes an output terminal, which is an outlet into which plugs of various devices (for example, an air conditioner, a rice cooker) can be inserted.

Next, the operation of the timer with the above configuration will be explained.

(1) When the pointer 25 is set to the "continuous" indication 24 In this case, only the first switch 11 is closed, as is clear from FIGS. 4 and 5 e. Therefore, the timer motor TM does not rotate, and the load connected to the output terminal 28 is in continuous operation.

(2) When the pointer 25 is set to the "OFF" display section from "OFF" to "ON" in the display 21 (for example, when the rice cooker is automatically activated in the morning), in this case, it is clear from Fig. As shown, only switch 12 is closed. Therefore, the timer motor TM rotates and advances in the direction of the arrow 29 from the position of the time set by the pointer 25 (for example, 8 hours), and the load connected to the output terminal 28 is not energized. In this state, as the preset time approaches the end, the positional relationships among the cams 3, 4, 5, levers 6, 9, 10, and switches 11, 12 are as shown in FIG. 5b. The timer motor TM rotates further and cams 3, 4, 5
When the main lever 6 further rotates in the direction of the arrow 29, the tip 6a of the main lever 6 falls to the lower part of the cam 3, and the driven lever 9
falls to the low stage part of the first contact cam 4, and the driven lever 10 rises to the high stage part of the second contact cam 5. Therefore, the first switch 11 is closed and the load is energized, and the second switch 12 is opened and the timer motor TM is stopped. In this state, the pointer 25 instructs the display 21 to display "on". Note that when the switches 11 and 12 are opened and closed as described above, the arrow 3 of the main lever 6
Since the driven levers 9 and 10 are moved in the direction of arrow 31 by swinging in the 0 direction, the relative movement speed between the cams 4 and 5 and the driven levers 9 and 10 becomes faster, and both switches 11 and 12 are moved at a higher speed. Closed or quickly opened.

(3) When the pointer 25 is set to the "ON" display section from "ON" to "OFF" display 20 (for example, when stopping the cooler at a certain time after going to bed), in this case it is clear from Fig. 4. In this way, both switches 11 and 12 are closed. Therefore, the timer motor TM rotates and the load is also operated.
When the set time elapses in this state, both switches 11 and 12 are opened as shown in FIGS. 5d to 5c, the timer motor TM is stopped, and the power to the load is also cut off. In this case as well, the switches 11 and 12 are operated quickly as in the previous case.

As described above, in the present invention, when it is desired to start energizing an electrical device after a predetermined period of time has elapsed (for example, when it is desired to turn on an electric kettle automatically the next morning), the input terminal 27 is connected to the power source. At the same time, connect the above-mentioned electrical equipment to the output terminal 28, turn the main shaft 2, and set the pointer 25 to the desired time scale 23 for the "off" section in the display section 21 from "off" to "on".
When the set time has elapsed, the second switch 12 closes and the timer motor is energized, the timer motor operates and the main shaft 2 begins to rotate, and when the set time elapses, the first switch 11 closes and the electricity is turned on. At the same time that the device starts to be energized, the second switch 12
When the main shaft 2 is opened and the timer motor is stopped, the main shaft 2 is stopped, and the electric device has the advantage of being able to continue to be energized.

On the other hand, if you want to stop energizing an electrical device after a certain period of time has elapsed (for example, if you want to turn off the air conditioner automatically after going to bed), connect the input terminal 27 to the power source and connect the electrical device to the output terminal 2.
8, and by turning the main shaft 2 and aligning the pointer 25 with the scale 22 of the desired time in the "ON" section of the "ON" to "OFF" display section 20, the first switch 11 is closed. At the same time, the second switch 12 is closed and the timer motor is energized, and the timer motor is activated and the main shaft 2 begins to rotate. When the set time has elapsed, the first switch 11 is turned on. opens to cut off the power to the electrical equipment, and at the same time, the second switch 12 opens and the timer motor stops, thereby stopping the main shaft 2 and maintaining the state in which the electricity to the electrical equipment is cut off. There is.

Moreover, even if an electrical device can be used in two ways, such as turning off the power to the device or turning it off after a predetermined period of time as described above, the setting operation must be performed in either way. Also, by turning one main shaft 2, set the pointer 25 to the desired time scale from "OFF" to "ON" or from "ON" to "OFF" where the desired action is displayed. The operation is simple because it can be done with a single operation of just aligning the position, and it is also useful because it prevents erroneous operations as in the past.
