Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a skylight opening/closing control device, and more particularly to a skylight opening/closing control device configured to accommodate a rain sensor in conjunction with closing of the skylight.

(Prior art) Skylights have traditionally been used for lighting and ventilation, and are either opened and closed manually, or automatically opened and closed by electric power if installed at a high place. There are various things.

Conventionally, skylights equipped with mechanisms that automatically open and close when the skylight is opened and closed have been equipped with a rain sensor, which detects when rain is falling while the skylight is open. There are some that automatically close skylights to prevent rain from blowing indoors.

(Problem that the invention aims to solve) However, in the case of conventional automatically opening/closing skylights that are equipped with a rain sensor, the rain sensor is always exposed outdoors, so dust, sunlight, rain, etc. Since the rain sensor is constantly exposed to the external environment and voltage is applied to the rain sensor, there is a problem in that the electrodes of the rain sensor are corroded by impurities contained in the rain, resulting in a decrease in sensitivity.

This rain sensor needs to be reliable enough to reliably detect rain and thereby close the skylight, and since it is installed on the roof, it needs to be reliable for several years without being replaced. It is hoped that the system will operate as expected.

Therefore, the present invention was conceived in view of the above problems, and its purpose is to improve the reliability of the operation of the rain sensor, and as a result, the skylight can be opened and closed reliably. Provides control equipment.

(Means for solving the problems) In order to achieve the above object, the present invention has the following configuration.

That is, in a skylight opening/closing control device equipped with a mechanism for automatically closing a skylight by detecting rain with a rain sensor 16, the rain sensor 16 is exposed outside the skylight when the skylight is opened, and when rain is detected, The rain sensor 16 is housed in the skylight in conjunction with an opening/closing mechanism that opens and closes the skylight, and is provided with a drain section 24 for removing raindrops 30 adhering to the rain sensor 16 on the path through which the rain sensor 16 enters and exits. do.

(effect) Next, we will discuss the action.

The rain sensor 16 goes in and out in conjunction with the opening and closing of the window section 10 of the skylight. When the window section 10 is open, the rain sensor 16 is exposed to the outside of the skylight, and when rain is detected by the rain sensor 16, the rain sensor 16 is retracted into the skylight in conjunction with the closing of the window section 10. be done. When the rain sensor 16 is stored in a skylight, the rain sensor 1 is
The raindrops 30 on top 6 are drained and stored.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described in detail based on the accompanying drawings.

FIG. 1 is a sectional view showing a storage section for a rain sensor in an embodiment of a skylight opening/closing control device according to the present invention;
Figures 2a and 2b are a side view and a plan view of the skylight opening/closing control device.

In FIG. 2, 10 is a window portion of a skylight, and 12 is a frame portion into which this window portion 10 fits. 14 is an opening. One end of the window 10 is hinged to the frame 12, and the other end is connected to a drive unit (not shown) such as a motor so that it can be opened and closed freely.

Reference numeral 16 denotes a rain sensor, which is provided so as to move between the inside and outside of the skylight in conjunction with the opening and closing of the window section 10. The electrodes of the rain sensor 16 are connected to a control section (not shown) of a predetermined rain sensor. The mechanism for moving the rain sensor 16 in and out will be described later.

18 is a storage box that stores the rain sensor 16. This storage box 18 is installed near the periphery of the frame 12, and the rain sensor 16 is installed in the vicinity of the periphery of the frame 12.

shows. In the figure, reference numeral 16 denotes the rain sensor, which rotates horizontally and is housed in the storage box 18 in conjunction with the closing of the window 10.

A sponge 30 is placed on the upper inner wall surface of the storage box 18, and is provided so as to come into contact with the top surface of the rain sensor 16 when the rain sensor 16 is stored in the storage box 18.

32 is a heater provided on the bottom surface of the storage box 18.

34 is a drainer provided at the entrance of the storage box 18, and 36 is an elastic body that sandwiches the drainer 24 and the rain sensor 16 from above and below. The draining section 34 is made of a flexible material such as rubber, and comes into contact with the top surface of the rain sensor 16 to remove water droplets attached to the top surface of the rain sensor 16. Also,
The elastic body 36 closes the entrance of the storage box 18 together with the draining section 34 when the rain sensor 16 is stored in the storage box 18.

Next, the mechanism for inserting and removing the rain sensor 16 will be explained. In FIG. 2b, one end of the rain sensor 16 on the base side is supported rotatably and is supported by a spring 20.
The rain sensor 16 is urged to rotate in the horizontal plane toward the storage box 18. A wire 22 is connected to the side of the rain sensor 16 inside the frame 12, and the other end of the wire 22 is connected to the rotating arm 24.

As shown in FIG. 2a, this rotating arm 24 is
The wire 22 is connected to the end of one arm extending downward, and the other arm projects upward from the frame 12 and connects to the window. It is configured to abut against the window portion 10 when the window portion 10 is closed.

A spring 26 is provided at the tip of the lower end of the rotating arm 24, and is a compression spring that constantly biases the rotating arm 24 in the counterclockwise direction in the figure. The strength of this spring 26 is determined by the strength of the rain sensor 1.
The rain sensor 16 is set to be stronger than the spring 20 that rotates the rain sensor 16, and when the window portion 10 is opened, the wire 22 is pulled to expose the rain sensor 16 to the outside of the skylight. Further, when the window portion 10 is closed, the rotating arm 24 is rotated clockwise in the figure, and the rain sensor 16 is housed in the storage box 18.

In FIG. 2b, the rain hits the paper from a direction perpendicular to the plane of the paper, and the rain sensor 16 is exposed from the storage box 18 to the outside of the frame 12 with the window 10 open. At this time, the rain sensor 16 is connected to a predetermined control section and energized. When raindrops fall on the rain sensor 16 in this state, the rain sensor 16 becomes conductive due to the raindrops, and rain is detected. When rain is detected, the drive section is immediately operated to close the window 10, and the rain sensor 16 is stored in the storage box 18 in conjunction with the lowering of the window 10.

When the rain sensor 16 is stored in the storage box 18, as shown in FIG. 1, raindrops 38 adhering to the top surface of the rain sensor 16 are removed from the surface by the draining section 34 as the rain sensor 16 moves. . As a result, the rain sensor 16 is drained in the storage box 18, and the moisture on the top surface of the rain sensor 16 is absorbed by the sponge 30.

Furthermore, by turning on the heater 32, the rain heater 16 can be heated to remove moisture. If the rain sensor 16 continues to be energized while wet, the electrode portion will corrode, so drying the rain sensor 16 in this manner is extremely effective in preventing the function of the rain sensor 16 from deteriorating.

Further, if the rain sensor 16 is housed in the storage box 18, the rain sensor 16 can be protected from dust and the like, which is suitable for maintaining the function of the rain sensor 16.

Further, when the window portion 10 is completely closed, the rain sensor 16 is housed in the storage box 18 and housed within the skylight, so that the rain sensor 16 is further protected. Incidentally, after the rain sensor 16 is stored in the storage box 18, the power supply to the rain sensor 16 is stopped. Rain sensor 16 of this embodiment
is exposed to the outside only when the window section 10 is open, and since water droplets are removed and stored in the storage box 18, there is no risk of corrosion of the electrode section, and the rain sensor 16 is prevented from deteriorating. This makes it possible to provide a sensor that can be used for a long period of time with significantly improved reliability.

Note that the sponge 30 may be of any type as long as it absorbs moisture on the rain sensor 16 and can protect the rain sensor 16 from dust or the like.

Further, a heater may be buried in the bottom side of the rain sensor 16 body, and in this case, it is possible to dry the rain sensor 16 body and detect snow with the same effect as the heater 32 described above. That is, since a rain sensor normally detects rain by sensing moisture, the rain sensor will not operate if only snow has adhered to it. However, if a heater is embedded in the rain sensor 16, when snow adheres to the rain sensor 16, the snow will melt and turn into water, allowing the rain sensor 16 to detect the snow, thereby making it possible to close the skylight. It is possible.

Note that the mechanism for moving the rain sensor 16 in and out is not limited to the embodiment described above, and various mechanisms are possible. As shown in FIG. 3, it may be provided so as to move in and out by moving back and forth in parallel. Also in this case, the provision of a drainer on the entrance side of the storage box 18 is the same as in the above example.

The present invention has been variously explained above using preferred embodiments, but the present invention is not limited to these embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. That's true.

(Effects of the invention) According to the invention, as described above, the rain sensor is linked to the opening and closing of the skylight and is configured to be exposed to the outside only when the skylight is opened. Since the rain sensor is housed in the rain sensor, the rain sensor is not constantly exposed to rain, etc., and deterioration of the rain sensor function can be suppressed. In addition, when storing the rain sensor, the drain section removes raindrops that adhere to the rain sensor, which prevents water from accumulating on the electrodes of the rain sensor, further improving the functionality of the rain sensor. It is effective in that it can be maintained.
