Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an air purifying device installed in offices, lobbies, homes, etc.

(Prior Art) Conventionally, as an air purifying device, one in which a blower device and a filter are provided in a housing having an inlet and an outlet is generally used.

[Invention tries to solve! ! Problem I: However, since the suction power depends only on the fan, it is not possible to draw in smoke from areas far away from the suction port.For example, if an air purifier is installed on the ceiling and you smoke below it In this case, cigarette smoke is not sufficiently sucked into the air cleaning device and is dispersed, resulting in a problem of poor air cleaning efficiency.

An object of the present invention is to provide an air purifying device that can efficiently suck air even at a location located downwardly away from the suction port.

[Means to solve the problem]

The air cleaning device of the present invention has an air cleaning device main body installed above and a heat source that generates an upward airflow below. The air purifier main body has an inlet on the lower surface and an outlet on the other surface, and is provided with a blower means and a means for purifying the passing air inside.

[Effect]

According to the configuration of the present invention, an ascending air current is generated by the heat source, and when it rises close to the suction port of the air purifying device main body, the rising air current is sucked together with the surrounding air by the suction force of the blowing means in the air purifying device main body. When the heat source is located close to the height of the suction port, the upward force from the heat source is added to the suction force of the blower to perform suction. The sucked air is purified by the purifying means and is discharged from the discharge port as clean air.

〔Example〕

A first embodiment of this invention will be described based on FIGS. 1 and 2.

A plurality of columns 2 are provided on the lower surface of an air purifying device main body 1, and the columns 2 are erected on a case 3 below. Air purifier body 1
The planar shape of the case 3 is circular or rectangular. The air purifier main body l has a suction port 4 on the bottom surface. Each of them has a discharge port 5 on the upper surface, and a fan 6 as a blowing means, a motor 7 for driving the fan 6, and a filter 8 as an air purifying means are provided inside. The filter 8 is for removing dust and deodorizing. The suction port 4 and the discharge port 5 are provided with a grid or a net.

In the case 3, a ring-shaped heater 9 serving as a heat source is installed on the bottom surface of the top plate, and an ashtray 10 is installed on the top surface of the top plate. As shown in FIG. 2, the heater 9 has a heating wire 9a covered with an insulating coating 9b made of ceramic or the like, and is screwed onto the case 3 with a hanger 11.

This air purifying device is placed on a table or floor. Smoke from a cigarette (not shown) placed in the ashtray IO becomes an upward air current a together with the surrounding air by heating by the heater 9.

Smoke flowing from directly below the suction port 4 to a location slightly away from the outer periphery is also caught up in the upward airflow a caused by the heater 9. Since the distance between the air purifier main body 1 and the case 3 is long,
The vertical range of the rising air flow a is wide, and smoke is easily drawn in.

When the rising air current a approaches the suction port 4 of the air purifier main body 1, it is sucked by the suction force of the fan 6, purified by the filter 8, and discharged from the discharge port 5.

In this way, the heater 9 below the suction port 4 generates the rising airflow a, so even if the source of dirt is far away downward from the suction port 4, it can be efficiently sucked in and remove the dirt. This prevents air from spreading to the surrounding area. Further, by placing the ashtray 10 in the case 3 provided with the heater 9 in this manner, it can be used as a smoking corner.

FIG. 3 shows a second embodiment. In this example, a hood 12 is provided around the lower surface of the air purifying device main body 1, and a ring-shaped heater 9 is provided on the inner periphery of the lower end of the hood 12. The other configurations are the same as in the first embodiment.

Even in the case of this configuration, the suction of the fan 6 is assisted by the generation of an upward air current by the heater 9.
Dirty air can be sucked in efficiently.

4 to 7 show third to sixth embodiments, respectively.

In the example shown in Fig. 4, a fluorescent lamp 1 serving as a heat source is installed inside the case 3'.
4. 15 is a lamp socket.

The fluorescent lamp 14 may be ring-shaped or linear, and the case 3' is formed of a translucent panel of milky white color or the like. The support column 2 and the air purifier main body l shown in FIG. 1 are installed on the case 3'.

With this configuration, the waste heat of the fluorescent lamp 14 can be effectively used as a heat source for the upward air current.

In the example of FIG. 5, the incandescent lamp 16 is replaced with the fluorescent lamp 1 of FIG.
This is provided in place of 4. 17 is a lamp socket.

In the example shown in FIG. 6, an opening 3a is provided on the upper surface of the case 3, and a hood 3b is provided around the opening 3a.

The other configurations are similar to the first embodiment. When the hood 3b is provided in this way, the rising airflow converges and a strong rising current can be obtained. Therefore, the effect of trapping smoke etc. is further improved.

Even if a hood 3b' is provided at the edge as shown in FIG. 7, the effect of converging the upward airflow can be similarly obtained.

FIG. 8 shows a seventh embodiment. In this example, a hood 18 protrudes diagonally outward from the periphery of the lower surface of the air purifier main body 1.
In addition, a fan 19 and a motor 20 for driving the fan 19 are provided inside the case 3. A case discharge port 21 is provided in the upper part of the peripheral wall of the case 3, and a case suction port 22 is provided in the lower part.

Further, a heater 9 is provided on the inner surface of the top plate portion of the case 3. The other configurations are similar to the first embodiment.

In this configuration, air around the case 3 is sucked in from the case suction port 22 by the fan 19 inside the case 3,
It is heated by the heater 9 and discharged from the case suction port 21. Since the discharged air is heated air, it becomes an upward current and rises around the air purifying device. This rising air current is collected by the hood 18 and sucked through the suction port 4. In this way, an ascending air current flowing around the air purifying device is obtained, so that the horizontal range of the ascending air current is widened, and the trapping area of dirty air is expanded.

FIG. 9 shows an eighth embodiment. In this example, the air purifying device main body (2) is erected in the center of the case 3 by one thick pipe-shaped support 2', and a coil-shaped heater 9' is provided within the support 2'. In this configuration, the surrounding air is warmed around the outer periphery of the support column 2' and an upward air current is generated. Other structural effects are the same as in the first embodiment.

〔Effect of the invention〕

In the air purifying device of the present invention, the heat source that generates the upward airflow is disposed below the suction port of the main body of the air purifying device, so that the upward airflow can assist the suction of the blowing means. Therefore, there is an effect that smoke located far away from the suction port can be efficiently sucked in.
