Abstract

PROBLEM TO BE SOLVED: To provide an air cleaner capable of collecting even air at the upper part of the air cleaner from a suction port without increasing the air cleaner size and cleaning the air in a wide range. SOLUTION: In the air cleaner provided with a main body having a suction port 2 and a discharge port 3, a blowing part 6 for allowing air to flow, and a filter 7 for cleaning the air, and having the suction port 2 on the upper part of the main body, the suction port is made into an inclined surface. Thus, not only the air at the front surface of the suction port 2 and the air flowing from the vicinity of the lower port of the main body toward the main body and striking against the surface of the front surface part of the main body and introduced into the suction port 2 along the surface, bus also the air at the upper part of the main body is sucked.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an air purifier for purifying indoor air in which dust and cigarette smoke are suspended.

[0002]

2. Description of the Related Art A conventional air purifier has a blower and a filter built in a main body provided with a suction port and a discharge port. In the air purifier, when the air blower is driven, the air in the room is sucked through the suction port, the dust in the air and the smoke of the cigarette are filtered by the filter, and the air is again blown out through the discharge port into the room. And such an air purifier was installed, for example on the indoor tabletop.

[0003]

However, in the above-described conventional air purifier, since the suction port is open in the front direction at the upper part of the front surface of the main body, the air in front of the suction port can be sucked. If the air flowing from the lower part of the main body toward the main body hits the surface of the front surface of the main body, it can be sucked because it is guided to the suction port along the surface, but the air above the main body could not be sucked. .

Therefore, in order to suck in the air flowing above the air purifier, the suction port must be located at a higher position, which causes a problem of increasing the size of the air purifier.

The present invention has been made in order to solve the above-mentioned problems, and an object of the present invention is to prevent air above the air purifier from the suction port without increasing the size of the air purifier. It is to provide an air purifier that can collect and purify a wide range of air.

[0006]

In order to solve the above problems, the present invention provides a main body having a suction port and a discharge port, and a blower section for flowing air. An air purifier having a filter for purifying air and having a suction port on an upper portion of the main body, wherein the suction port is an inclined surface.

The invention according to claim 2 is characterized in that a rib for dividing the suction port into a plurality of portions is provided in front of the suction port.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION A first embodiment of an air purifier according to the present invention will be described with reference to FIGS. 1 to 5, and a second embodiment will be described with reference to FIG.

[First Embodiment] FIG. 1 is a sectional view of an air purifier. FIG. 2 is a perspective view of the air purifier. FIG.
5 is a cross-sectional view of the air purifier showing the flow of air sucked into the air purifier.

In FIG. 1, the main body 1 is a substantially box-shaped body,
It has a suction port 2 and a discharge port 3. The suction port 2 is shown in FIG.
As shown in FIG. 2, the opening 1 is an opening provided in the slope 1c formed by cutting the corner formed by the top plate 1a and the front plate 1b of the main body 1, and is a part that sucks in air. The discharge port 3 is an opening provided in the upper surface plate 1a of the main body 1 and is a portion for discharging air.

As shown in FIG. 1, the main body 1 has a partition plate 4 inside, and the space inside the main body 1 is divided into front and rear by the partition plate 4, and the ventilation paths 5 and 6 extending vertically. Is formed. The ventilation passage 5 and the ventilation passage 6 communicate with each other at a lower portion in the main body 1, the ventilation passage 5 communicates with the outside through the suction port 2, and the ventilation passage 6 communicates with the outside through the discharge port 3. Communicate.

A filter 7 for adsorbing dust and particles of cigarette smoke passing through the ventilation passage 5 to purify the air and deodorize the air.
And a blower 8 for flowing a predetermined amount of air. The blower unit 8 includes a cross-flow fan 8a and a drive motor (not shown) that drives the cross-flow fan 8a.

When the cross-flow fan 8a is driven, the air purifier constructed as described above passes from the suction port 2 through the ventilation passage 5 and the ventilation passage 6 as shown by the arrow in FIG.
An air flow that flows to the discharge port 3 is formed.

As shown in FIG. 3, the air flowing from the vicinity of the lower portion of the main body 1 of the air cleaner toward the main body 1 is
When it hits the surface of the front plate 1b, it is guided to the suction port 2 along the front plate 1b and is sucked into the main body 1 along the path shown by the arrow.

Further, as shown in FIG. 4, the air in the vicinity of the front of the suction port 2 is sucked from the suction port 2 along the path indicated by the arrow when the cross flow fan 8a is driven.

As shown in FIG. 5, the air above the suction port 3 is also sucked from the suction port 2 through the path indicated by the arrow when the cross flow fan 8a is driven.

Therefore, the air purifier can suck in a wide range of air, can capture mainstream smoke and sidestream smoke floating in the air in the range by the airflow, and can suck the air together with the air from the suction port 2. The filter 7 can clean dust in the air and smoke of cigarettes.

[Second Embodiment] FIG. 6 is a sectional view of an air purifier. FIG. 7 is a perspective view of the air purifier. In addition,
In FIG. 6, the same reference numerals are given to the same parts as those of the air purifier described in the above-described first embodiment, and detailed description of the same parts will be omitted.

The air purifier according to the second embodiment shown in FIGS. 6 and 7 is different from the air purifier described in the above-described first embodiment in that it has the following features.

That is, as shown in FIGS. 6 and 7, the suction port 2
A rib 9 that divides the suction port 2 into a plurality of parts is provided in front of. The rib 9 is a plate whose length in the longitudinal direction is the same as the width of the inclined surface portion 1c, and is provided such that the upper surface of the rib 9 has substantially the same height as the upper surface plate 1a.

Therefore, the suction port 2 is divided into two by the rib 9, and the opening area when the suction port 2 is viewed from above the main body 1 is reduced by providing the rib 9. Since the flow rate of the air blown by the cross-flow fan 8a is constant, the opening area is reduced, and the flow velocity of the air is increased. Therefore, when the rib 9 is provided, the flow velocity at the time of sucking the air above the air purifier is increased, and the collection ability is improved.

In the first and second embodiments, the blower section 8 is described as having the cross-flow fan 8a. However, the blower section 8 is not limited to the cross-flow fan, and a sirocco fan is used. You may comprise using.

[0023]

Since the air purifier of the present invention is constructed as described above, in the invention of claim 1, since the suction port is an inclined surface, the air in front of the suction port, Not only the air that flows from the vicinity of the lower part of the main body toward the main body and hits the surface of the front surface of the main body and is guided along the surface to the suction port, but also the air above the main body can be sucked in, so that the size of the air purifier is increased It is possible to provide an air purifier capable of purifying a wide range of air without collecting air above the air purifier from the suction port.

According to the second aspect of the present invention, the first aspect is provided.
In addition to the effects of the invention described, the rib in front of the suction port divides the suction port into a plurality of parts, and reduces the opening area of the suction port, so that the flow velocity at the time of sucking air is increased and the trapping ability is improved. The effect that an air purifier capable of being provided can be provided.
