Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an air purifier that purifies the air inside a car or a room.

Configuration of conventional examples and their problems Among conventional air purifiers, there are home air purifiers that are mainly used at home, such as in cars and indoors, and recently, due to market demands, miniaturization has progressed.

However, in order to ensure the minimum necessary dust collection efficiency and air volume, it is becoming difficult to further reduce the filter area and fan size. In line with the increasing demand for products with a well-balanced design and high performance.

Purpose of the invention The present invention solves these conventional problems and aims to provide a compact, well-balanced design, high performance, and inexpensive air purifier.

Structure of the invention In order to achieve the above object, the invention consists of an outer shell of a rectangular main body, an upper part of the main body having an air intake port on the upper surface, a motor supported on the upper surface of the central part, and a ventilation hole formed around the upper part of the main body. It also consists of a main body support plate with radial ribs on its upper surface centered around this vent, and a lower main body with an exhaust port on its circumferential surface,
A horizontal filter supported on ribs is placed in the space above the main body support plate, and a centrifugal fan driven by the motor is placed in the space below.

In this way, by using a centrifugal type fan and by placing the filter horizontally in parallel with the fan, a thin air purifier can be provided.Moreover, the air flow guiding action of the ribs makes it possible to provide a thin air purifier. This allows efficient air purification.

Description of examples Examples thereof will be described below with reference to the accompanying drawings.

In Figures 1 to 7, 1 is the upper part of the air purifier, 2 is the main support plate that is the middle part, and 3 is the main body support plate that is the middle part.
is the lower part of the main body, and inside the main body, a motor 4 is provided at the center of the main body support plate 2, and a thin centrifugal fan 5 is provided on the lower side of the main body support plate 2. Upper part of main body 1
An intake port 6 and a filter 7, which is a combination of a charged filter and an activated carbon filter, are attached to the holder. An exhaust port 8 is provided on the side surface of the lower part 3 of the main body. The bottom surface of the lower body part 3 having the centrifugal fan 5 is substantially rectangular, and the body support plate 2 and the upper body part 1 are fixed with screws by tightening bosses 10 formed in partition walls 9 provided at the four corners.

Ribs 11 are provided radially on the upper part of the main body support plate 2 to support the filter 7 attached to the upper part 1 of the main body, and a vent hole 12 is provided in the center of the main body support plate 2 to communicate with the centrifugal fan 5. There is. A locking recess 13 is provided in the front part of the upper part 1 of the main body, and a buckle 14 that can be freely moved in and out is provided on the main body support plate 2 in correspondence with the locking recess 13. A resistor 15 for switching the strength of the motor 4 is arranged between the centrifugal fan 5 provided on the side of the lower part 3 of the main body support plate 2 and the partition 9, and the resistor 15 is connected to the receiving rib 16 provided on the lower part 3 of the main body and the main body support. It is held by a support boss 17 provided on the plate 2, and the lead wire 1
8 is drawn into the partition wall 9 through a notch 19 provided in the partition wall for wiring.

The buckle 14 is attached to a boss 20 formed on the main body support plate 2.
The buckle is urged outward by a spring 21 provided between the buckle and the boss 20, and a groove 22 of the buckle is fitted into the boss 20 to serve as a guide. Also, the boss 20 has a washer 23.
is attached with a screw 24, and a buckle 14 is attached slidably.

A stopper 25 is formed on the side surface of the buckle 14, and is abutted by an outer peripheral rib 26 of the main body support plate 2 to prevent it from coming off. Numeral 27 is a locking pawl that locks into the locking recess 13 of the upper part 1 of the main body to fix the upper part of the main body.

Reference numeral 30 denotes a perfume case, which is provided in one corner of the lower part 3 of the main body so as to be freely accessible. Notch 3 provided in fragrance case 30 from partially open wall 32 formed in lower part 3
3 constitutes a passage for air to be discharged through the notch 35 on the knob 34 side. 36 is fragrance case 3
It is a fragrance-impregnated felt placed inside. 37
39 is a protrusion provided on the fragrance case insertion guide rib 38 provided on the lower part 3 of the main body, and 39 is a recess provided on the lower surface of the fragrance case 30.

In the above configuration, when the power is turned on, the centrifugal fan 5 connected to the motor 4 rotates, and the intake port 6
More air is sucked in. When the sucked airflow passes through a filter 7 that is a combination of a charged filter and an activated carbon filter, particulates and odors are removed, and it passes through a radial passage provided by ribs 11, a vent 12, a centrifugal fan 5, and an exhaust port 8. When replacing the filter 7, press the buckle 15, lift the upper part 1 of the main body upward, disengage it from the main body support plate 2, and remove the filter 7. It can be removed and replaced, and is easy to operate by simply removing the buckle 5.

The resistance 15 for switching load, which causes the centrifugal fan 5 to increase or decrease the airflow by reducing the current to the motor 4, generates heat due to power consumption by the resistance 15 during low operation. Since the exhaust gas flows directly, it is cooled, the temperature rise is small, and stable operation is possible.

Also, to hold the resistor, after setting it in the lower part 3 of the main body,
It can be easily assembled by just covering the main body support plate 2. Since the wiring can be concentrated within the partition wall 9, the wiring portion does not touch the centrifugal fan 5, and a thin air purifier that can be used safely is constructed.

The motor 4 is provided at the center of the main body support plate 2, and is cooled by the airflow passing through the filter 7, so that the temperature rise is small and problems such as motor burnout are less likely to occur.

Further, when the fragrance case 30 is located at a distance from the wall 32 as shown in FIG.
The fragrance is emitted from the notch 33 through the space between the wall 32 and the fragrance case 30, and the fragrance emitted from the fragrance-impregnated felt along with the fragrance is discharged from the notch 35 to the outside of the vessel. Furthermore, when the fragrance case 30 is used by being pushed inside, the notch 33 is brought into close contact with the wall 32, closing the air passage and stopping the emission of fragrance. It has a structure that allows it to be stopped.

Effects of the invention As described above, according to the invention, since the radial ribs are provided on the upper side of the main body support plate, the air distribution distribution to the filter is equalized, and the overfunction can be maximized. This rib brings the air that has passed through the filter to the center and reduces the resistance at that time, so the airflow efficiently flows to the centrifugal fan, and the ribs that support the centrifugal fan, filter, and filter are It can be constructed thinly, and in addition, a centrifugal fan is constructed on the lower side of the main body support plate, and the airflow that passes through the filter and gathers at the center of the main body support plate is guided directly to the centrifugal fan, making the overall structure extremely compact and thin. We are now able to provide purifiers. In addition, a large rectangular surface can be secured as a filter area, making it possible to construct an air purifier with a thin, compact, and well-shaped design. Furthermore, since it can be installed in narrow spaces, it can be used in cars that have been difficult to install, such as cars with narrow rear windows, greatly expanding the range of applications.
