Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a delay switch.

[Prior Art] Conventional delay switches are disclosed, for example, in Japanese Utility Model Application Publication No. 1983-31724 (hereinafter referred to as the "former") and Japanese Patent Application Laid-Open No. 1982-81073 (hereinafter referred to as the "latter"). There is something like that.

The former consists of a main circuit consisting of a power supply, a lighting load, and a C-type switch, an operating circuit connected to one of the switching contacts of the C-type switch and connected to the power supply via a time-limiting contact and a ventilation load, and a control circuit of the C-type switch. A common terminal is connected to one of the switching contacts of the C-type switch which is interlocked, one switching contact is connected to the lighting load via the B-type switch, and the other switching contact is connected to the lighting load via the timer that opens and closes the time-limited contact at a set time. The device is characterized by a time-limited circuit connected to both ends of the device, so that it can be used, for example, in a bathroom or toilet, and after the lighting load is turned off, the ventilation load is driven for a certain period of time.

In addition, in the latter case, an interlocking sliding part is formed on the side of the operating handle for switching contacts, a push button for time-limited contact operation is arranged parallel to the operating handle, and a protrusion provided on the side of the operating handle is provided. It is characterized by being opposed to the interlocking sliding part of the operating handle, so that the time-limiting contact can be held in a closed state and the contact of the contact can be switched by a single operation from the outside.

[Problems to be Solved by the Invention] However, in the conventional delay switch as described above, in the former case, the main circuit, the operation circuit, and the time limit circuit are formed in one circuit. The structure was such that the power used by the ventilation load and the power used by the lighting load were integrated into one wattmeter.
Therefore, when a delay switch with such a configuration is used, for example, in an apartment building, the power consumed by each unit by indoor lights in the entrance hall, etc., and the power consumed by common facilities such as outdoor fluorescent lights around the hallway are combined into one unit. Since the electricity is integrated into the electricity meter, there was a problem in that it was not possible to distinguish between the electricity consumed by each household and the electricity consumed by shared equipment.

In the latter case, the upper end of the operating handle and the upper end of the push button are exposed independently from the mounting frame, and it is necessary to select and push the operating handle and push button separately depending on the purpose of use. First, if the selection is incorrect, a load other than the intended one will be activated, which poses the problem of easy operation errors.

The present invention was made in view of these conventional problems. For example, the power used by indoor lights, etc. is integrated into a wattmeter installed in each house, and the power used by outdoor lights, etc. is integrated into shared equipment. To provide a delay switch which can be integrated into the wattmeter of a common light, can control the blinking of indoor lights and outdoor lights from the room of each house, and can achieve energy saving.

[Means for Solving the Problems] In order to solve the above problems and achieve the object of the present invention, the delay switch according to the present invention is characterized by being configured as follows. That is, an indoor circuit has an indoor power supply 7b and a load 9 connected in series, an outdoor circuit has an outdoor power supply 7a and a load 8 connected in series, and one pole is connected in series with the indoor circuit. an outdoor opening/closing part 1 in which the other pole is connected in series to the indoor opening/closing part 12 and the outdoor circuit;
1, and by the opening/closing operation, one opening/closing part is brought into a closed state and the other opening/closing part is brought into an open state.
The pole switch 10 is connected in series to the indoor opening/closing part 12 or the outdoor opening/closing part 11, and
It is characterized by having a delayed opening/closing mechanism section 13a that opens or closes with a delay from the opening/closing operation of the pole switch 10.

A slow-acting opening/closing mechanism section 13a is provided in series with the outdoor opening/closing section 11 which is in the state of operation, and which opens with a delay from the OFF operation of the two-pole switch 10.

The external structure of the delay switch main body 1 in the first embodiment described above is shown in FIGS. 3 and 4. FIG. 3 is a plan view of the delay switch main body 1, and FIG. 4 is a front view thereof. In the figure, 22 is a case, and a lid 23 is attached and fixed to the upper part of this case 22 by mounting fittings 24, 24. An operator 25 of the two-pole switch 10 is partially exposed through the upper opening of the lid 23.

The interior of the delay switch main body 1 is shown in FIGS. 5 to 9. FIG. 5 is a plan sectional view showing the internal structure of the delay switch main body 1, FIG.
The figure shows a cross section taken along the line A-A in FIG. 3 with a part omitted, FIG. 8 shows a cross section taken along the line B-B in FIG. 5 with a part omitted, and FIG. C
It is a diagram showing a cross section taken along the line -C with some parts omitted.

As shown in FIGS. 5 and 6, the interior of the delay switch body 1 includes a portion where external connection terminals 2, 3, 4, 5, etc. are provided, and a delayed opening/closing mechanism portion 13a, etc. It is broadly divided into parts.

First, the structure of each part of the former will be explained based on FIGS. 5 and 6. The external connection terminal 2 includes a terminal plate 26 forming a peripheral wall and a presser spring 2 disposed inside the terminal plate 26.
7, it is formed as a so-called quick connection terminal that clamps the electric wire inserted into the case 22 from the electric wire insertion hole 28. Other external connection terminal 3,
Similarly, terminals 4 and 5 are formed as quick connection terminals.

Next, the structure of each part on the installation side, such as the slow-acting opening/closing mechanism part 13a, will be explained. Slow opening/closing mechanism section 13a
As shown in FIGS. 6 and 9, the main shaft 31 includes a timer body 30 and a main shaft 31 for winding up a spring (not shown) in the timer body 30 and extracting the return force of the spring as rotational force.
Then, by rotating this main shaft 31, the slow opening/closing mechanism section 1
3a, a fixed cam 33 and a movable cam 34 attached to the main shaft 31, and a notch hole 36 formed on the periphery of the movable cam 34 rotatably attached to a support shaft 35. It consists of a cam crank 38 with which the portion 37 is engageable.
This cam crank 38 locks the latch portion 3 when the movable cam 34 rotates in the same direction as the winding lever 32 winds up (rotating clockwise in FIG. 9).
7 escapes from the notch hole 36. A micro switch 20 as an on/off switch is disposed near the slow-acting opening/closing mechanism section 13a. As shown in FIGS. 6 and 8, the opening and closing operations of this microswitch 20 are regulated by an operating protrusion 39 of a cam crank 38. Although not shown in the figure, the micro switch 20 connects electricity between the external connection terminals 2 and 3 in FIG. 1, and between the external connection terminals 2 and 3 and 4 and 5 in FIG. It is connected.

In the above-mentioned slow movement mechanism section 13a, a partition plate 40 is provided above the area where the micro switch 20 and the like are arranged, and the operator 25 is arranged on the partition plate 40 as shown in FIG. As shown in FIG. 7, the fulcrum shaft 25a of the operator 25 extends laterally from the center of the bottom, and is in contact with the movable spring 41.
The tilting motion about the fulcrum shaft 25a is disciplined. A neon tube 42 is attached to the inner hollow part of the operator 25, as shown in FIG. The neon tube 42 is connected in series with a resistor as shown in FIGS. 1 and 2, and is connected in parallel with the outdoor opening/closing part 11 between the external connection terminals 2 and 3. A hood 43 is attached to the upper surface of the operator 25 through which light from the neon tube 42 can pass, so that the energization state can be confirmed from the outside.

The slow opening/closing mechanism section 13a and the operator 25 described above operate in conjunction with each other by the following configuration. That is, a starting protrusion 44 is formed at one end of the bottom of the operator 25 . Reference numeral 45 in the figure denotes a holder that is swingably provided around a support shaft 46 and is biased counterclockwise in FIG. It engages with the movement of and swings clockwise. A locking step portion 45a capable of locking the winding lever 32 of the slow-acting opening/closing mechanism portion 13a is formed on the side wall of the holding body 45. That is, the winding lever 32 rotates clockwise in FIG.
When the winding lever 32 is in the set state, the tip of the winding lever 32 is locked as shown in the figure. This locked state is released when the holding body 45 rotates clockwise in FIG. 9 due to the engagement of the starting protrusion 44. In addition, 48 in the figure is a timer winding piece, and the upper end is in contact with the end on the side where the starting protrusion 44 is formed at the bottom of the operator 25, and the lower end is in contact with the winding lever 32 of the slow-acting opening/closing mechanism part 13a. It is being Therefore, the operator 25
When the winding lever 32 tilts clockwise in FIG. 9, the winding lever 32 rotates clockwise in the same figure in conjunction with the tilting.
The slow opening/closing mechanism section 13a is set.

Next, the operation of the delay switch 10 having the above-described configuration will be explained.

First, the mechanical operation of the delay switch main body 1 will be explained. When the operator 25 is tilted clockwise in FIG. 9 to the state shown in the figure, the winding lever 32 connected to the operator 25 through the timer winding piece 48 is also moved clockwise in the figure. It rotates, and the slow opening/closing mechanism section 13a is set. At this time, the holding body 45 swings counterclockwise in FIG. 9 due to the biasing force of the spring 47 to lock and hold the winding lever 32. Further, the cam crank 38 is connected to the movable cam 34.
The latch portion 37 escapes from the notch hole 36 and rotates counterclockwise in FIG. 9 about the support shaft 35.

As a result, the microswitch 20 is maintained in a closed state by the operating protrusion 39 of the cam crank 38. Conversely, when the operator 25 is tilted counterclockwise in FIG. 9, the holding body 45 is swung clockwise in the figure by the starting protrusion 44, and the locking state of the winding lever 32 is released. Then, the slow opening/closing mechanism section 13a
is activated, the movable cam 34 rotates counterclockwise in FIG.
The latch portion 37 of No. 8 is engaged. Thus, the cam crank 38 rotates clockwise in FIG. 9, and the micro switch 20 becomes open. in this way,
The delay switch main body 1 has a so-called delay operation function in which the microswitch 20 becomes open after a predetermined time delay after the operation of the operator 25.

Next, the electrical operation of the first embodiment will be explained based on FIG. As shown, the two-pole switch 10 is
In the ON state, that is, when the indoor opening/closing section 12 is brought into a closed state, the indoor light 9 is turned on. On the other hand, the outdoor opening/closing section 11 is in an open state, and the outdoor fluorescent lamp 8 is turned off. Therefore, when going out, the two-pole switch 10 is turned off, the indoor light 9 is turned off, and the outdoor opening/closing part 11 of the two-pole switch 10 is closed, and the outdoor fluorescent lamp 8 is turned off. The outdoor fluorescent lamp 8 is connected in series to the slow opening/closing mechanism section 13a, that is, the outdoor opening/closing section 11, and opens or closes with a delay from the opening/closing operation. The opening/closing mechanism section 14 turns off the light after a certain period of time. Therefore, the outdoor fluorescent lamp 8 is turned off after a certain amount of time has elapsed, such as 60 seconds after the user has walked away from the room.

When going home, the reduced number of outdoor lights are turned on by a sensor installed near the entrance of the building, allowing you to return home, and when you return home and turn on the 2-pole switch 10, the indoor lights 9 are turned on. The outdoor fluorescent lamp 8 remains turned off, but when the two-pole switch 10 is turned off, after a certain period of time has elapsed since the outdoor fluorescent lamp 8 was turned on, the number of lights turned on by the detection sensor is reduced. The lights will be turned off at approximately the same time as the outdoor lights.
In this way, the above-mentioned operations can be performed with only one switch operation, and there is an energy saving effect.

FIG. 10 shows the external structure of the delay switch main body in a second embodiment of the delay switch. FIG. 10 is a plan view of the delay switch body. Further, the internal structure of the delay switch main body is shown in FIG. FIG. 11 is a plan sectional view of FIG. 10 with the partition plate and pressing spring removed. The delay switch main body in the second embodiment of the delay switch can have a structure substantially similar to that of the delay switch described above.

In the second embodiment, the slow opening/closing mechanism section 13
a and 13b are shared, and the slow opening/closing mechanism section 13
Main shafts 31 are installed on both sides of the timer main body 30 of a and 13b.
The main shaft 31 is rotated to operate the movable cams 34 on both sides to perform setting. Furthermore, the movable spring 41 is provided only on the external connection terminals 2 and 3 side, and
It is not provided on the 5th side. External connection terminals 2 and 3
As shown in FIG. 2, a primary winding 51 of a current transformer 50 is provided between the current transformer 50 and a light emitting diode 53 and a secondary winding 52 of the current transformer 50.
53 is electrically connected. Furthermore, light emitting diodes 53, 5 are provided on the upper surfaces of the light emitting diodes 53, 53.
A hood 54 that can transmit light from 3 is attached, so that the energization state can be confirmed from the outside.

Next, the electrical operation of the second embodiment will be explained based on FIG. 2. As shown, the two-pole switch 10 is
After the indoor opening/closing section 12 is brought into the ON state, that is, the indoor opening/closing section 12 is brought into the closed state, the indoor light 9 is turned off after a certain period of time by the delayed opening/closing mechanism section 13b, which opens later than the OFF operation of the two-pole switch 10. On the other hand, when the two-pole switch 10 is turned OFF, the outdoor opening/closing section 11 is turned off.
becomes a closed circuit state, and the outdoor fluorescent lamp 8 lights up, but
Since an outdoor side slow-acting opening/closing mechanism section 13a is connected in series to the outdoor side opening/closing section 11 and opens with a delay from the OFF operation of the two-pole switch 10, the outdoor fluorescent lamp 8 is turned off after a certain period of time.

Therefore, when going out, turn on the two-pole switch 10.
When turned OFF, the slow-acting opening/closing mechanism section 1 on the indoor side
3b, the indoor light 9 is turned off after a certain period of time, for example 30 seconds, so the room remains bright until the user goes outside. When you go outside, the outdoor fluorescent lamp 8 is on, so you can walk without any inconvenience, and after a certain amount of walking and a certain amount of time has elapsed, for example, 60 seconds, the slow-acting opening/closing mechanism outside the room opens. 1
3a turns off the outdoor fluorescent lamp 8. When going home, a sensor installed near the entrance of the building turns on the reduced number of outdoor lights, allowing you to return home and turn on the two-pole switch 10.
When turned on, the indoor light 9 lights up and the outdoor fluorescent light 8 remains off, but the two-pole switch 10
When turned off, after a certain period of time has elapsed since the outdoor fluorescent lamp 8 was turned on, it is turned off at approximately the same time as the reduced number of outdoor lights that were turned on by the detection sensor are automatically turned off. In this way, the above-mentioned operations can be performed with only one switch operation, and there is an energy saving effect.

Further, each slow-acting opening/closing mechanism part 13a is connected directly or in series to the opening/closing part 11 or 12 of each pole and opens and closes with a delay from the opening/closing operation,
For example, as in the second embodiment, the timer device 13, which is the delayed opening/closing mechanism section 13b that opens with a delay from the OFF operation of the two-pole switch 10, can be provided with different delay times. Seconds later,
Since the delayed opening/closing mechanism section 13a, which opens with a delay from the OFF operation of the two-pole switch 10, can be changed to suit the actual situation, such as 60 seconds later, the energy saving effect is further improved.

[Effects of the Invention] As is clear from the above description, according to the present invention, each switch is operated with a certain time delay by just one switch operation, and it is possible to increase the energy saving effect and to save energy indoors. The power used by lights, etc. is totaled on the wattmeter installed in each house, and the power used for outdoor lights, etc. is shared equipment, so it is totaled on the wattmeter of the shared light. A delay switch can be provided that can distinguish between the consumed power and the consumed power. In addition, since the blinking of indoor lights and outdoor lights can be controlled from inside each house, and the delay time can be changed depending on the actual situation, it is possible to provide a delay switch that is highly energy-saving. can.

Therefore, conventionally in condominiums, etc., switches were attached to each of the indoor lights at the entrance, outdoor fluorescent lights around the hallway, etc. in order to save energy, but according to the present invention, it is possible to save energy by operating each switch. No need to do it, no hassle,
It is possible to provide a delay switch that can fully exhibit energy saving effects.
