  The electronic circuit unit 4 is electrically connected to the plurality of terminal units 3, 3, 3, 3, and turns the load on and off by electrically connecting or disconnecting the load and the AC power source. As shown in FIGS. 3B and 4, the mounting board 40 connected to the terminal plate 30 of each terminal portion 3 by solder, the flat cable 41, and the board 40 through this are electrically connected. And a mounting board 42.

  The mounting board 40 includes an electric wire 40a that electrically connects both patterns connected to the outer terminal portions 3 and 3 in the housing recesses 10d and 10d among the patterns connected to the terminal portions 3, and In addition to mounting the relay 40b as a switching element connected between the patterns connected to the inner terminal portions 3 and 3, various components constituting various circuit portions are mounted. For example, it is connected to both patterns connected to the terminal portions 3 and 3 in one housing recess 10d, and the AC power from the AC power source is rectified and smoothed to DC power to each portion in the mounting boards 40 and 42. A power supply circuit section to be supplied is mounted. The mounting board 40 is screwed to the body 10 with a screw S2 in a state where the side of the electric wire 40a and the relay 40b is housed in the body 10 and the pattern surface is directed forward.

  As shown in FIGS. 2 and 4, the mounting substrate 42 includes a liquid crystal panel 42 a and an LED 42 b disposed behind the window hole 110 a, the window hole 110 b, and the plurality of flexible portions 110 c to 110 h of the cover 11 of the container 1, respectively. 42b and a plurality of tact switches 42c to 42h are mounted on the front surface.

And screwed to the cover 11.

  The control circuit unit has a timekeeping function and the like, and executes processing such as control of the entire time switch. For example, when the tact switches 42d to 42h are turned on by a setting operation on the operation units 2d to 2h, the set contents are displayed on the liquid crystal panel 42a, and various set time information is stored in, for example, a memory in the microcomputer 42i. Is executed. Thereby, for example, the current time is set for the clocking function. Further, a predetermined timer time for automatic on / off for timer 1 (“auto 1” in FIG. 1A) and a predetermined timer time for automatic on / off for timer 2 (“auto 2” in FIG. 1). Also, the predetermined timer time information is stored in the memory by setting. The operation unit 2d for the off timer also functions as a predetermined off timer time setting switch (see the fourth embodiment described later).

  Further, when the tact switch 42c is turned on in response to an on / off operation unit 2c, the control circuit unit turns on the load by turning on the relay 40b, and the on / off operation unit. When the tact switch 42c is turned on in response to the turning operation for 2c, control is performed to turn off the load by turning off the relay 40b. These on / off operations are periodically switched every time the tact switch 42c is turned on.

  Further, the control circuit unit changes the operation mode to both the timer 1 and timer 2 operation modes each time the tact switch 42e is turned on in response to an operation on the operation unit 2e for automatic operation selection, as shown in FIG. The timer 1 operation mode, the timer 2 operation mode, and the both operation stop mode are periodically switched and set, and the setting content indicating which mode is set is displayed on the liquid crystal panel 42a. When the operation mode is set to both the timer 1 and timer 2 operation modes, the timer 1 automatically turns on and off at a predetermined timer time and the timer 2 automatically turns on and off at a predetermined timer time. At the same time, control for automatically turning on / off the load is performed by turning on / off the relay 40b. When the timer 1 operation mode is set, the control for automatically turning on / off the load is performed by turning on / off the relay 40b in accordance with the timer time for the timer 1. When the timer 2 operation mode is set, the control for automatically turning on and off the load is performed by turning on and off the relay 40b in accordance with the timer time for the timer 2. On the other hand, when the operation mode is set to the both operation stop mode, the control for automatically turning on and off the load is stopped.

  Further, the control circuit unit gives priority over the operation of turning on / off the relay 40b in accordance with the timer time and the operation of turning on / off the relay 40b in accordance with the on / off operation as shown in FIG. Execute load control. That is, when the tact switch 42d is turned on in response to the cut-off timer operation on the operation unit 2d for the cut-off timer, the cut-off timer time (for example, a preset 60 minutes) from the time when the cut-off timer is operated and By turning the relay 40b on and off after the elapse of time, control for turning on and off the load is executed during the off timer time and after the elapse of the off timer time.

  As for the specific method of priority, if the operation mode at the time of the turning-off timer operation is an operation mode corresponding to the turning-on / off operation with respect to the on / off operation unit 2c, the current operation mode is used. The operation mode corresponding to the timer operation is prioritized. As a result, after the relay 40b is turned off by the turning-off timer operation (see FIG. 6 (a)), when an on operation is performed, the operation mode is shifted to the on operation. In addition, the operation mode when the off timer is operated is a timer 1 operation mode (including timer 1 operation mode of both timer 1 and timer 2 operation modes) or a timer 2 operation mode (timer 2 of timer 1 and timer 2 operation mode). If an operation mode is included), the operation mode corresponding to the operation of the cut-off timer has priority over the current operation mode. As a result, after the relay 40b is turned off due to the turning-off timer operation (see FIGS. 6B and 6C), when the current time by the timekeeping function becomes a new timer time in the timer 1 operation mode or the timer 2 operation mode, The operation mode is changed according to the timer time.

  Further, the control circuit unit performs control to turn on / off the current on / off state of the relay 40b, that is, the on / off state of the load by, for example, lighting, turning off, blinking, or color-coded display of the LEDs 42b, 42b.

  Next, an example of the procedure for assembling the time switch will be described. First, each terminal portion 3 is housed in each housing recess 10d of the body 10, and the electric wire 40a and relay 40b side of the mounting board 40 is housed in the body 10, with its pattern surface facing forward. Then, the mounting substrate 40 is screwed to the body 10 with the screw S2. At this time, each terminal board 30 may be soldered to the mounting board 40 in advance, or may be soldered after the mounting board 40 is stored in the body 10.

  Subsequently, the mounting board 42 is stored behind the cover 11, the pattern surface thereof is directed rearward, and the mounting board 42 is screwed to the cover 11 with screws S 3. Thereafter, the opening edge portion 10b of the body 10 and the opening edge portion 11b of the cover 11 are combined to close the opening 10a of the body 10 with the cover 11, and each screw S1 is inserted into each screw insertion hole 10c of the body 10. The feet are inserted and the body 10 and the cover 11 are screwed with the screws S1.

  Subsequently, each locking piece of the decorative cover main body 20 of the decorative cover 2 is locked to each locking hole 8 a of the front surface portion 110 of the cover 11 of the container 1, and the decorative cover 2 is locked to the cover 11 of the container 1. Removably attach to. Thereby, the assembly of this time switch is completed.

  Next, an operation example of this time switch will be described. First, the operation of the time switch according to the operation on the on / off operation unit 2c will be described. For example, when the load is turned off, an on / off operation unit 2c is turned on, and when the tact switch 42c is turned on, the relay 40b is turned on and the load is turned on, and the load is turned on by the LEDs 42b and 42b. The status is lit. After that, when the on / off operation unit 2c is turned off and the tact switch 42c is turned on, the relay 40b is turned off and the load is turned off. Is done. Thereafter, the same operation is periodically repeated every time the operation unit 2c is pushed.

  Next, the operation of this time switch according to the automatic operation selection operation for the operation unit 2e will be described. When the tact switch 42e is turned on by operating the operation unit 2e for automatic operation selection, the operation mode is set to the timer 1, timer 2 both operation mode, timer 1 operation mode, timer 2 operation mode or both operation stop mode. At the same time, the setting contents of the automatic operation mode are displayed on the liquid crystal panel 42a (see FIG. 1A). When the operation mode is set to both the timer 1 and timer 2 operation modes, the timer 1 operation mode, or the timer 2 operation mode, the timer 1 automatically turns on / off, the predetermined timer time and the timer 2 The relay 40b is turned on and off in accordance with at least one of the predetermined timer times of automatic on and off, and the load is automatically turned on and off. On the other hand, when the operation mode is set to the both operation stop mode, the control for automatically turning on and off the load is stopped.

  Next, the operation of the time switch according to the operation on the operation unit 2d for the off timer will be described. As shown in FIG. 6 (a), when the load is off, the timer is turned off, and when the tact switch 42d is turned on, the load is turned on for the duration of the timer after the timer is turned off. The load is turned off after the timer expires.

  As shown in FIG. 6B, when the load is automatically turned on, and when the load is turned on for a longer time (2 hours in the figure) than the turn-off timer time by the turn-off timer operation, the turn-off timer operation is performed. When the tact switch 42d is turned on, the load is continuously turned on from the time when the turn-off timer is operated to the turn-off timer time, and the load is turned off after the turn-off timer time has elapsed. Thereby, the automatic on-time can be shortened to the off timer time by the off timer operation.

  As shown in FIG. 6 (c), when the load is automatically turned on and the power is turned on for a shorter time (30 minutes in the figure) than the time when the power is turned off, When the tact switch 42d is turned on, the load is continuously turned on from the time when the turn-off timer is operated to the turn-off timer time, and the load is turned off after the turn-off timer time has elapsed. Thereby, the automatic on-time can be extended to the off timer time by the off timer operation.

  As described above, according to the first embodiment, the off timer regardless of the on / off operation of the time switch in accordance with the timer time of the timers 1 and 2 and the on / off operation of the time switch according to the on / off operation. If the operation is performed, the load is turned on during the off timer time, and the load is turned off after the off timer time elapses. Therefore, the load can be easily adjusted without resetting the timer times of the timers 1 and 2.
