Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a device that has a function of purifying indoor air and a function of actively generating fragrance in a room.

(Prior art and its problems) In the past, devices for purifying air and devices for generating fragrance were manufactured separately, which led to high production costs and the need to operate both devices indoors. When using it, the power cord had to be connected to an outlet separately, making it inconvenient to use.

(Technical Means for Solving the Problems) In view of the above problems, the present invention aims to provide a device that is both inexpensive and easy to use.
A first ventilation passage and a second ventilation passage which are independent of each other are formed in the casing 1, and a first fan 21 and an air filter 22 driven by a first motor 20 are provided in the first ventilation passage. The air introduced from the intake port 15 of the ventilation path is purified and sent out from the ventilation port 16, and a second motor 2 is installed in the second ventilation path.
3 and the second fan 24 driven by the air freshener 2
5 is installed, and the fragrance is delivered to the intake port 1 of the second ventilation path.
The air is sent out from the air outlet 19 along with the air introduced from the air outlet 8.

(Example) Examples of the present invention will be described below based on the drawings.

In FIGS. 1 to 4, a casing 1 is composed of a casing body 2 and covers 3A and 3B removably attached to both left and right ends of the casing body 2. The casing body 2 is composed of an upper wall 4, a bottom wall 5, front and rear side walls 6, 7, and left and right end walls 8, 9, and the interior is divided into an upper chamber 11 and a lower chamber 12 by a horizontal partition 10. The lower chamber 12 is divided by a vertical partition wall 13 into two left and right compartments 12a and 12b. The covers 3A and 3B are each formed in the shape of a box with one side open, and the respective opening surfaces are connected to the left and right end walls 8 and 9 of the casing body 2.
It is placed facing the outside. The inside of the left cover 3A and the left compartment 12a of the casing body 2 are communicated through a communication port 14 opened in the end wall 8, and an air intake port 15 consisting of a large number of slits is provided on the outer surface of the left cover 3A. In addition, the bottom wall 5 forming the left partition wall 12a is provided with an air blowing port 16 consisting of a large number of slits. 12a and the air outlet 16 form a first ventilation path.
The inside of the right cover 3B and the right compartment 12b are communicated with each other through a communication port 17 opened in the end wall 9, and the bottom wall 5 forming the right compartment 12b has a large number of holes. Inlet port 18 consisting of a slit
, and an air outlet 19 consisting of a large number of slits is also provided on the outer surface of the cover 3B, so that the air inlet 18, compartment 12b,
The communication port 17, the inside of the cover 3B, and the ventilation port 19 form a second ventilation path that is separate from the first ventilation path.

In the first air passage, a first fan 21 that is rotationally driven by a first motor 20 and sucks air from the intake port 15 is attached to the inner end of the communication port 14 , and is attached to the outer end of the communication port 14 . An air filter 22 is removably attached. In the second ventilation duct,
The intake port 18 is rotated by the second motor 23.
A second fan 24 that sucks more air is connected to the communication port 17.
The air freshener 25 is attached to the inside of the cover 3B, and a fragrance 25 is placed inside the cover 3B in a suitable container. The aromatic agent 25 is either solid or liquid, and the container can be replaced when it is consumed.

A first fan 21 for purifying indoor air through an air filter 22 and a second fan 24 for forcibly sending fragrance into the room are electrically connected to the first motor 20 and the second motor 23. A connected control device (not shown) causes intermittent operation (steady operation) at predetermined timing in normal times, and the first fan 21
By using the above-mentioned control device, it is possible to maintain the operating state or the stopped state for a relatively long time by pressing the push button switch 26 for forced operation when necessary. First fan 21, second fan 24
During operation, indicator lamps 27 and 28 are illuminated, respectively. The forced operation push button switch 26 and indicator lamps 27 and 28 are provided on the front side of the casing body 2, as shown in FIG. FIG. 5 shows the first fan 21 controlled by the control device.
This explains the operation of the second fan 24, and the first fan 21 is turned on and off every 30 minutes, for example.
The OFF operation, that is, activation and stopping, is repeated, and if the push button switch 26 is pressed once while it is stopped, the operation will be forcibly started from that point on, and the operating state will be maintained for, for example, 2 hours. It will now be automatically stopped when
After that, normal operation will resume and it will operate every 30 minutes.
The stoppage is repeated. When the push button switch 26 is pressed once while the first fan 21 is in operation, the operation is forcibly stopped at that point and the stopped state is maintained for two hours, which is the same as the above-mentioned operating time.
After that time has elapsed, the device returns to normal operation and starts and stops repeatedly. Although not shown in FIG. 5, if the push button switch 26 is pressed twice in succession while the first fan 21 is in operation, the operating state will be maintained for two hours, and furthermore, if the push button switch 26 is pressed twice while the first fan 21 is stopped. If you press it once, the stopped state will be maintained for 2 hours. Therefore, for example, when the air in the room is very dirty, by pressing the push button switch 26 only once when the first fan 21 is stopped in normal operation, and twice when it is in operation, It can purify the air for 2 hours,
In addition, when there is almost no pollution in the indoor air,
The air purifying action can be stopped for two hours by pressing the push button switch 26 twice when the first fan 21 is stopped in steady operation, or only once when it is in operation. Furthermore, this push button switch 2
Since the forced activation and forced stop according to No. 6 are limited to a predetermined period of, for example, two hours as described above, so-called "forgetting to turn off" or "forgetting to turn on" can be prevented. On the other hand, regarding the second fan 24, for example, as shown in FIG.
It is designed to operate for only 3 minutes or 6 minutes per hour, and switching between the 3 minute and 6 minute operation times can be performed by an appropriate switch.

Further, a digital clock 29 is provided at the center of the front surface of the casing body 2.

(Effects of the invention) This invention combines an air purification device and a fragrance generating device into one.
Since both devices are integrated into one casing, the production cost can be lower than when both devices are manufactured separately as in the past. Code is also 1
It is easy to use as it only requires a book and requires less installation space. Furthermore, since the first fan and the second fan are rotationally driven by separate motors, there is an advantage that the air purification operation and the forced fragrance generation operation can be performed simultaneously or separately as necessary. .
