Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an air purifier that reduces the intake resistance of a blower fan.

BACKGROUND OF THE INVENTION In recent years, air purifiers have become widely used in general households to improve the living environment.

Conventionally, this type of air purifier has generally had a configuration as shown in FIG.

The configuration will be described below with reference to the drawings.

As shown in the figure, a main body 1 is provided with a dust filter 2 and a deodorizing buoy letter 3 for purifying contaminated air, and a blower 4 for taking in and exhausting room air. The blower 4 is composed of a motor 6 that drives a seven-wheel drive unit 5 and a fan case 7.

To explain the operation in the above configuration, when the motor 6 is driven, the fan 5 rotates, and the indoor air is pumped through the dust filter 2.
The air is then exhausted through a deodorizing filter 3.

In this way, the conventional air cleaner described above can also purify dirty air when it passes through the deodorizing filter 3.

Problems to be Solved by the Invention In such a conventional air purifier, the air intake port 9 of the blower 4
is provided at the center of the partition wall 8 on the intake side of the fan case γ, so that when the air passes through the deodorizing filter 3 and is taken into the fan case 7, the side of the fan 6 and the fan case 7
A vortex is created between the partition walls 8 on the intake side, and air is not drawn in effectively.
There was a problem in that the intake air volume decreased.

The present invention solves the above problems, and aims to provide an air purifier that can increase the air volume by lowering the resistance caused by the partition wall of the fan case and the eddy current of the fan.

Means for Solving the Problems In order to achieve the above object, the present invention has a first means for solving the problems. A fan case that guides air to the exhaust port, a dust collection filter installed on the intake side of the fan case to purify the air, and a deodorizing filter on the intake side of the dust collection filter and the fan case. The partition wall has an intake port and a large number of small holes located around the intake port, and the second problem solving means is that the partition wall on the intake side of the fan case has an inner guide wall having a large number of small holes and an outer guide wall. It consists of guide walls, and a deodorizing material is arranged between the guide walls.

Effects In the above configuration, the effects of the first problem solving means are as follows:
The inside of the partition wall of the fan case becomes negative pressure, and the air is also taken in through the many small holes provided on the intake side of the fan case, that is, from the entire surface of the dust collection filter and deodorizing mail letter, so the air is drawn in between the partition wall and the fan. The vortex flow is reduced, and therefore the air resistance is lowered and the air volume is increased. The effect of the second problem-solving means is that a deodorizing material with low air resistance is inserted between the guide walls having a large number of small holes, so that the resistance of the air passing through the guide walls is lowered and the air volume is increased.

Embodiments Hereinafter, embodiments of the present invention will be explained without reference to the drawings.

FIG. 1 and FIG. 2 show an embodiment related to the means for solving the first problem of the present invention. In this embodiment, the same components as those shown in the above-mentioned conventional example are given the same reference numerals, and the explanation thereof will be omitted. The characteristic structure of this embodiment is that a large number of small holes are provided in the partition wall on the intake side of the fan case described in the conventional example. That is, the air intake port 12 is provided in the center of the partition wall 11 on the air intake side of the fan case 7 that constitutes the blower 4 of the air purifier. and bulkhead 1
A large number of small holes 13 are provided on the outer periphery of the intake port 12 for air to pass through.

To explain the operation in the above configuration, when the motor 6 is driven, the fan 5 rotates and the indoor air is transferred to the dust filter 2.
The air is then exhausted through the deodorizing filter 3, but since the air taken in here passes through the intake port 12 and small hole 13 of the partition wall 11, the vortex between the partition wall 11 and the fan 6 is reduced, and the air The resistance is lowered and the air volume of the fan 6 can be increased.

FIG. 3 and FIG. 4 show an embodiment related to a child actor to solve the second problem of the present invention. The difference from the first problem solving means (is the partition wall 16 on the intake side of the fan case γ).
1 consists of an inner guide wall 16 and an outer guide wall 17 having a large number of small holes 13, and a granular deodorizing material 18 with low air resistance is enclosed between the guide walls,
With this configuration, by inserting a deodorizing material with low air resistance between the guide walls, the resistance of the wind passing through these is lowered and the air volume can be increased, and the filter housing can be made thinner, saving space. It has the effect of becoming.

Note that in the above embodiment, the partition wall 15 has an inner guide wall 16 and an outer guide wall 17 having a large number of small holes 13;
The partition wall 15 may be a wire mesh with low air resistance. In this case, the effect is that air resistance can be further reduced.

Effects of the Invention As is clear from the above description of the embodiments, the air purifier of the present invention includes a motor provided in the main body, a fan driven by the motor, and a system that exhausts the air blown by the fan. A fan case that leads to the mouth, a dust collection filter installed on the intake side of this fan case to purify the air,
This dust collection filter and a deodorizing filter are provided on the intake side of the fan case, and the bulkhead on the intake side of the fan case has an intake port and a large number of small holes located around the intake port to collect dust. By lowering the air resistance of the dust filter, the air volume can be increased, and by keeping the air volume the same, the rotation speed of the fan can be lowered, reducing noise.
