Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air purifier, and more particularly, to an apparatus having a heat source installed in a living space or a conference room, which utilizes air convection generated by the heat of the heat source. The present invention also relates to an air purifier configured to remove (deodorize and smoke) odors caused by indoor smoking, cigarette smoke and other dust.

[0002]

2. Description of the Related Art Recently, in living spaces and conference rooms,
Two types of air purifiers are used to remove odors caused by smoking, smokes from cigarettes, and other dusts (deodorization and smoke removal). One of them is equipped with a fan and a filter. This is usually installed in one corner of the floor in the room,
A fan rotated by a motor sucks indoor air into the air purifier, passes dirty air through a filter to deodorize and smoke, and returns the cleaned air to the room again.

The other type is called an electron ion type, which is also usually installed at one corner of the floor in the room, and the corona discharge charges fine particles such as odors and smoke in the air to negative ions to ionize them. The fine particles are attracted to an internal positive electrode by an electric field generated around the air purifier, and are adsorbed and removed.

[0004]

However, the former air purifier requires external power (electric power) for rotating the motor fan, and must be equipped with a power source thereof, which results in high operating cost. There is. There is also a problem that noise is generated because the motor fan is rotated.

In addition, the latter air purifier does not use a motor fan and thus produces a relatively quiet operating noise and consumes little power. However, this causes particulates such as odors and smoke (depending on the electric field) in the vicinity thereof. Because of the pulling method, there is a problem that the air cleaning speed is much slower than that of the former air cleaner that sucks the air in the entire room by a fan.

The present invention has been made to solve the above problems. That is, the object of the present invention is not particularly required external power to clean the air,
An object of the present invention is to provide an air purifier that can suppress operating noise.

[0007]

Means for Solving the Problems As a result of intensive studies for solving the above problems, the present inventor has found that indoors are usually provided with a lighting device such as a fluorescent lamp or an incandescent lamp, and the floor surface in winter. We paid attention to the fact that the stove and electric heater are installed in the. That is, since these devices inevitably generate heat (or are heating elements themselves), the present invention has been completed by paying attention to the fact that air convection due to heat is generated around them as a heat source.

The present invention is provided corresponding to a device having a heat source, and an air cleaning section having a function of deodorizing and / or smoke removal is arranged at a place where air convection generated by the heat of the heat source passes. The above object is achieved by providing an air purifier characterized by the above. The above-mentioned air convection means a flow of air that occurs when heated air receives buoyancy, and this includes not only vertical upward airflow, but also air flowing diagonally or laterally depending on surrounding conditions. The flow of is also included.

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show an embodiment of the air purifier of the present invention, FIG. 1 is a longitudinal sectional view thereof, FIG. 2 is a perspective view, and FIG. 3 is a bottom view.

The air purifier of the present embodiment uses the light source of a normal lighting fixture installed in a room as a heat source.
As shown in FIG. 1, a pipe-shaped suspending tool 51 hangs downward from a ceiling 70, and a casing 30 having a shape in which a cylindrical upper surface is closed is attached below the suspending tool 51 (see FIG. 2). The trapezoidal umbrella-shaped body 20 is attached, and two electric lamp supports 21 are hung below the periphery of the umbrella-shaped body 20 (see FIG. 3), and the electric lamp (ring-shaped fluorescent lamp) 10 is attached thereto. I am supported.

As shown in FIG. 2, the housing 30 is provided with four circular air circulation holes 31 on each of its upper surface and side surface. The material of the housing 30 is not particularly limited, but plastic or metal is used in this embodiment.

Further, as shown in FIG. 1, the umbrella-shaped body 20 is provided with a circular hole 22 at the center, and a filter 23 (which is usually used in an air conditioner or the like) is provided so as to close the hole 22. It is installed (see Figure 3). The filter 23 is attached from below the umbrella-shaped body 20 with a wing nut (not shown). Also, the above-mentioned electric lamp support 2
1 is made of an elastic strip-shaped metal plate, the lower end of which is curved in a circular shape, and the electric lamp 10 (the ring portion of the fluorescent lamp) is sandwiched and supported by the curved portion. The material of the umbrella-shaped body 20 is not particularly limited, but in the present embodiment, plastic or metal that does not transmit air and that well reflects the light rays emitted from the electric lamp 10 is used.

An air purifying filter 41 having a function of deodorizing and / or smoke removal is housed in the inner space of the filter housing frame 40 composed of the umbrella-shaped body 20 and the housing 30.
This constitutes the air cleaning unit 50 of this embodiment.
The above "deodorization and / or smoke removal" means that either one of deodorization or smoke removal may be performed, or both deodorization and smoke removal may be performed. The air cleaning filter 41
In this embodiment, a futon-like filter having both deodorizing and smoke removing functions, which is formed by filling a special deodorizing fiber with a density that allows air to pass therethrough, is used.

Further, in this embodiment, a motor fan 60 capable of blowing air from bottom to top is provided above the filter 23 in the central portion of the umbrella-shaped body 20. Also, light 1
0 and the electric wiring to the motor fan 60 are passed through the inside of the pipe-shaped suspending tool 51 and then laid inside the filter housing frame 40 (the housing 30 and the umbrella-shaped body 20) as shown in FIG. Is installed.

In the air purifier of the present embodiment constructed as described above, the air warmed by the heat of the electric lamp 10 below the umbrella-shaped body 20 naturally rises to form a truncated cone-shaped umbrella. Collected in the middle along the lower surface of the body 20, first the filter 23 removes the relatively large dust, then passes through the air cleaning filter 41 to be deodorized and de-smoked for cleaning. It goes out into the room through the air circulation hole 31.
That is, when the electric lamp 10 is turned on, an air flow shown by the broken line in FIG. 1 is generated. In addition, as the air around the electric lamp 10 rises, the air near the lower part of the electric lamp 1 is successively changed.
It is drawn toward 0, and air circulation occurs throughout the room.

Therefore, the air purifier of this embodiment can pass the dirty air in the room through the air purifying filter 41 without the need for a fan for circulating the air. External power for operating the fan is not required, and the operating noise of the air purifier can be suppressed.

In this embodiment, the motor fan 60
However, by rotating the motor fan 60, the upward airflow due to the air convection is accelerated, so that the air in the room can be purified more quickly. Therefore, when the operation of the air purifier in which the air is relatively dirty is started, the motor fan 60 can be rotated to improve the start-up of the air purifier.

Further, in the air purifier of this embodiment, since the air purifying section 50 is arranged above the electric lamp 10 as described above, the upward airflow can easily pass through it (the filter 23 and the air purifying filter 41). , There is no danger of overflowing to the side and making a detour. Therefore, the air is efficiently purified.

Further, since the umbrella-shaped body 20 is formed in the shape of a truncated cone, the ascending air current generated by the heat of the electric lamp 10 is effectively arranged along the lower surface of the umbrella-shaped body 20 in the air cleaning filter 4.
Collected in the central hole 22 leading to 1. Further, since the umbrella-shaped body 20 is provided on the upper side of the electric lamp 10, the rising airflow is easily directed to the inside of the air cleaning unit 50 by the umbrella-shaped body 20, and there is no fear of escaping to the side. In addition, the filter 23 is the umbrella-shaped body 2.
Since the wing nut is attached from the lower side of 0, cleaning by detaching it is easy.

In addition, in living spaces and conference rooms,
Since there are many people directly under the light 10 and smoke is emitted when there is a person who smokes, the light 10 installed above the floor (around the ceiling 70) is installed. The air purifier of the present embodiment is particularly effective for deodorizing and removing smoke.

Further, since the electric lamp 10 is usually installed in the upper center part of the room, the air purifier of this embodiment, which is attached to the electric lamp 10, is equipped with (an air purifier installed in one corner of the floor of the room). It is advantageous for deodorizing and smoking in the whole room (compared to the container).

Further, the air purifier of this embodiment has a ceiling 70
Since the air purifying unit 50 is provided above the electric lamp 10 close to
Even if the amount of the air cleaning filter 41 is increased and the air cleaning unit 50 becomes slightly bulky, there is an advantage that it is less likely to get in the way. Further, since the electric wiring 10 has already been subjected to electric wiring work, there is an advantage that a motor fan with a smoke sensor (corresponding to the motor fan 60) can be installed without an outlet.

The present invention is not limited to the above-mentioned embodiment, and any light source of the above-mentioned lighting equipment may be used as long as it generates heat, and an incandescent lamp may be used. Also,
The heat source may be a stove or an electric heater. Further, the umbrella-shaped body may have a truncated pyramid shape or a bowl shape, and the housing may have a rectangular tube shape with an upper surface closed. Further, the air circulation hole may not be provided on the side surface portion of the housing. Further, the air cleaning unit may be arranged below the light source of the lighting fixture as long as it does not interfere with the lighting. Also, as an air cleaning filter,
Deodorants such as activated carbon and other smoke removers may be used. Further, although the motor fan is provided in this embodiment as an example, it goes without saying that the motor fan may not be provided.

Further, the air cleaning section may not be directly attached to the equipment having the heat source as in the above embodiment, but may be arranged at a position considerably separated from the heat source. Further, for example, when the heat source is provided in a duct bent in an L-shape and air convection occurs laterally with respect to the heat source, the air cleaning unit may be arranged laterally with respect to the heat source. Even in this case, the air cleaning unit may be arranged on the outlet side (high temperature side) of the heat source with respect to the air flow or on the inlet side (low temperature side) of the heat source. Further, an electron ion type air purifier may be arranged as the air purifying unit and the electron ion type air purifier may utilize air convection.
