Description

Energy-saving ventilator using optical sensor {omitted}

The present invention relates to a power-saving ventilator using an optical sensor, and more particularly, to a ventilator that ventilates muddy air in a room, in the case of general home and commercial use that is not a special use, a user forgets to blink and does not turn off the ventilator at midnight. In addition, the present invention relates to a ventilation device configured to have a power saving effect that is prevented from unnecessary waste due to operation after working hours.

The ventilator is an important device for living the muddy air to the outside, and is used in most toilets, offices, and businesses.

However, it is often forgotten to turn off the power of the ventilator, and in this case, it is not necessary to ventilate in the middle of the night, or even after working hours, it is often unnecessary power wasted.

To date, many devices have been developed in connection with the fan. For example, a ventilator that operates according to a gas state of a room using a gas sensor, and a ventilator that operates according to a room temperature using a temperature sensor. However, the apparatuses are used in factories, vinyl houses, etc., where gas is discharged a lot, and thus, the fans may be used for special purposes rather than for the effect of power saving. The ventilator by the sensor is judged to be unsuitable for a business such as an office or a restaurant that focuses on continuously operating for a predetermined time or during working hours.

As a fan device for power saving, there is a "power saving driving method of the fan" filed by the Korean Patent Office of Daewoo Electronics Co., Ltd. on June 29, 1995. This device is designed to reduce unnecessary power consumption by automatically operating for a certain period of time only when a person's entrance is detected by using a human body sensor or when there is no person's entrance for a long time. However, the device may be useful for a toilet that is sometimes used by a person, but is inappropriate for a business such as an office or a restaurant that requires continuous ventilation.

There is currently no same technology as the power saving fan apparatus for controlling the operation of the fan by sensing the presence or absence of light with a light sensor (cds), such as a power saving fan using the optical sensor related to the present invention.

The present invention was devised to solve the above problems, and the fan is operated even when the user forgets and does not need to turn off the fan so that power is unnecessarily wasted. The purpose of the sensor (cds) is to provide a power-saving ventilator using an optical sensor that detects this in the middle of the night or when the lights in the shop are turned off and automatically stops the operation of the fan.

In addition, since the function can be selected according to the user's environment, the purpose is to increase the convenience of use.

The following drawings attached to this specification are illustrative of preferred embodiments of the present invention, and together with the detailed description of the invention to serve to further understand the technical spirit of the present invention, the present invention is a matter described in such drawings It should not be construed as limited to.

Energy-saving ventilator using an optical sensor according to the present invention to achieve the above object body (11); A selector switch 13 installed at the front of the body 11 to select a function; An optical sensor (cds) 24 installed inside the body 11 to sense light; A transformer 23 for supplying an appropriate voltage to the optical sensors (cds) 24; A relay drive circuit 25 for supplying or cutting off power by an electric signal of the optical sensor (cds) 24; An optical sensor (cds) opening 15 on the front of the body 11; A pull / down switch 14 used for manual operation; And an air vent mechanism 22.

Preferably, the device is preferably the same as the power supply of the existing ventilator, it is preferable to configure the same pull line pull pull down switch as the existing ventilator to reduce the additional manufacturing cost as much as possible.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, terms or words used in the specification and claims should not be construed as having a conventional or dictionary meaning, and the inventors should properly explain the concept of terms in order to best explain their own invention. Based on the principle that can be defined, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention. Therefore, the embodiments described in the specification and the drawings shown in the drawings are only the most preferred embodiment of the present invention and do not represent all of the technical idea of the present invention, various modifications that can be replaced at the time of the present application It should be understood that there may be equivalents and variations.

Although the present invention suggests that the power is applied or cut off by the light signal using only the optical sensors (cds), a timer or the like may be additionally installed to be configured to operate after a predetermined time after the detection of the light.

1 is a plan view showing the overall configuration of a power saving fan using an optical sensor according to the present invention, Figure 2 is a circuit diagram showing the connection of components of the power saving fan using the optical sensor shown in FIG.

Referring to the drawings, the energy-saving ventilator using the optical sensor of the present invention further includes a selector switch 13 and an optical sensor (cds) opening 15 to allow a function selection to a conventional general ventilator body 11 housing. The optical sensor (cds) opening 15 is installed in the optical sensor (cds) opening portion 15 to detect the presence of light.

Since the operation state of the ventilator varies according to the function selection, the following description will be given based on the selection state of the selector switch 13 for function selection.

First, when the selector switch 13 of the energy-saving ventilator using the light sensor is positioned at "auto", the light is detected by the light sensor (cds) 24, and when the light is detected, the fan is automatically operated to operate the evening. When the sun goes down, it detects this and automatically cuts off the power supply so the fan stops working. When using "automatic", ventilation is required during the daytime, but the temperature drops during the night, so the ventilator is only activated when the lighting is turned on. It is suitable for restrooms in the building and offices and restaurants where people work from morning to work and leave for dinner. Even if you forget to turn off the fan and leave the office at night or when there is no light inside, it automatically cuts off the power, which can prevent unnecessary power waste.

Next, when the selector switch 13 is placed in the "semi-automatic" position, the user must pull the fan pull / down switch 14 to operate the fan, and in the evening or when the room light is turned off, the light sensor (cds) 24 ) Detects this and shuts off power to the fan. "Semi-automatic" is suitable for businesses that go to work in the afternoon. In the morning, when the sun does not work immediately and the user goes to work and forgets to turn off the fan after the business is over, and the light is turned off even after work, the light sensor (cds) 24 detects this and cuts off the power supply. This stops the operation of the power, which can prevent the maximum power consumption.

Finally, when the selector switch 13 is positioned "manual", the power can be applied or cut off only by the pull / down switch 14, similar to the existing fan. In the case of using "manual", it is suitable for the shop which uses a fan irregularly or is used for 24 hours. Even in these establishments, it is possible to switch to "automatic" or "semi-automatic" as needed to provide an opportunity to prevent unnecessary power waste.

Referring to FIG. 2, a timer may be further installed in a circuit of a power saving fan using the optical sensor of the present invention. The role of the timer is to allow the light sensor (cds) 24 to apply power after a certain time after detecting the light, so that the fan can be operated automatically in a place where there is no need for ventilation in the afternoon or after work. It is also preferable to add as a thing to give.

As described, the energy-saving fan using the optical sensor of the present invention is a device that can prevent the unnecessary power is wasted as much as the user forgets to turn off the fan from time to time.

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto and is intended by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of the claims to be described.

The energy-saving fan using the optical sensor according to the present invention described above is configured by additionally configuring a minimum circuit in the existing fan, thereby preventing unnecessary waste of power by operating the fan at unnecessary times when the user does not inadvertently turn off the fan. This has the advantage of reducing power consumption as much as possible.

In addition, since the function can be selected according to the user's use environment, the device adds convenience of use.
