DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the illustrated embodiments. In FIGS. 1 and 2, reference numeral 1 is a housing, and a horizontally long suction port 2 is provided in the upper front portion of the housing. Vertically long outlets 3 and 3 are provided on the left and right upper portions, respectively, and further outlets 3 are provided on the rear side of the upper surface of the housing 1. The housing 1 is provided with a blower fan 4 that sends out the air sucked from the suction port 2 toward the blowout ports 3, 3, 3.

In this air blower, the air blown from each of the blowout ports 3, 3, 3 forms an air curtain surrounding the front space of the housing 1, and the turbulent airflow flows into the front space of the air blower. prevent. Therefore, when there is a smoker in the space in front of the housing 1, it is possible to obtain the barrier effect of preventing the diffusion of the smoke of the cigarette due to the disturbance airflow by the blowing air, and to surely suck the smoke from the suction port 2. To do. If an air purifying filter 5 is arranged between the suction port 2 and the blower fan 4 in this air blower as shown in FIG. 3, it is possible to collect cigarette smoke and it is expensive. You can obtain the collection efficiency and prevent cigarette smoke from disturbing your neighbors.

The front suction port 2 is provided in the upper front portion of the housing 1 so that the sidestream smoke rising from the cigarette placed on the ashtray on the desk can be put on the suction wind toward the suction port 2. Therefore, it becomes easier to suck the sidestream smoke, and at this time, the suction wind speed of the suction port 2 is set to 1
If it is set to m / sec or more, the ascent rate will be 0.1 to 0.2 m.
It is possible to reliably suck in the sidestream smoke, which is about / second. The suction port 2 is not provided on the entire front surface of the housing 1 but is elongated and made small horizontally so that the suction air volume can at least increase the suction air velocity.

Further, it is preferable that the wind speed ratio between the suction wind speed of the front suction port 2 and the blowing wind speed of the left and right blowing ports 3, 3 is 1: 1 to 4. If the blowing air velocity is slower than this, it is more likely to be affected by external winds such as air-conditioning winds and the suction efficiency becomes poor, and if the blowing air velocity is faster than this, smoke is drawn into the flow of the blowing wind and diffuses. Therefore, the smoke suction efficiency can be maintained at a high level by setting the above range.

It is desirable that the outlet 3 provided on the upper surface is provided near the rear portion. This is because it is possible to avoid mutual influence with the wind sucked into the front suction port 2.
As shown in FIG. 2, the air flow path from the blower fan 4 arranged in the lower portion of the housing 1 to the blowout port 3 arranged on the rear upper surface of the housing 1 is arranged in the vertical direction along the back plate of the housing 1. The reason why the length is linearly extended is to improve the directivity of the air flow discharged upward, which is advantageous for forming the air curtain.

The suction port 2 at the upper part of the front face and the outlets 3 at the left and right sides of the front face are separated by a predetermined distance L. This is to prevent a vortex from being generated by the suction wind at the suction port 2 and the blowing air blown out from the left and right front blowing ports 3 and 3, and by preventing the generation of the vortex by securing the distance L. Therefore, it is possible to improve the feeling of suction. The distance L varies depending on the wind speed of the sucking wind and the wind speed of the blowing air. When the sucking wind speed is 0.7 m / s and the blowing wind speed is 1 m / s, when the distance L is 20 mm, it is good. I was able to obtain a good result.

In the embodiment shown in FIG. 4, the outlets 3 and 3 arranged on the left and right sides of the front surface of the housing 1 are vertically elongated over substantially the entire length of the housing 1, so that the left and right air curtains are more reliably formed. For this reason, it is shown that the sidestream smoke or the like is not allowed to affect the neighbors on the desk for this reason, and the embodiment shown in FIG. The blowout port 3 arranged in the above is provided with a guide 30 that spreads radially inside the blowout port 3.
The figure shows that the wind blown from the air is spread over a wide area in the left-right direction to prevent smoke from leaking.

As shown in FIG. 6, by providing an obliquely upward wind direction adjusting plate 39 on the rear surface side of the blowing port 3 arranged on the rear side of the upper surface of the housing 1, the blowing air is directed upward obliquely toward the front. It shows what was done. In this case, the effect of sucking smoke is improved by entraining the sucked air, and the leakage of smoke to the rear of the housing 1 is reduced. As shown in FIG. 7, the height of the suction port 2 is set to be equal to that of the blowing port 3 on the upper surface side.
If it is made higher, the amount of smoke that is not sucked into the suction port 2 and flows toward the upper surface outlet 3 side is reduced, and the smoke suction efficiency is increased.

In the embodiment shown in FIG. 8, the lower portion of the suction port 2 of the housing 1 is made detachable, and at this time, the air cleaning filter 5 can also be removed. . In this case, when the air cleaning filter 5 is replaced or washed, it is possible to expose the inner surface of the suction port 2 which is the most easily soiled portion, so that the cleaning is facilitated, and the removable portion is entirely washed. Will also be possible.

In the apparatus shown in FIGS. 9 to 11, the left and right outlets 3, 3 are provided as slits formed in the rotatable cylindrical body 31 so that the outlet direction can be changed from the front to the side. In addition to the above, it is possible to adjust the wind direction in the vertical direction by adjusting the louver 33 arranged in the outlet 3. Reference numeral 34 in FIG. 11 is a connecting piece for interlocking the louvers 33. In this case, it can be used regardless of the positional relationship between the place where the air blower is placed and the smoker. Adjust the blowing direction shown in Fig. 10 (a) (b) to approximately 90 ° from the front to the side.
If possible, it is possible to ensure that an air curtain is formed between the smoker side and the person on the opposite side. It is desirable that the blowing can be stopped (FIG. 10 (c)). Due to the positional relationship between the installation location and the smoker, even if the blowing wind may hit the person, it is possible to reduce the draft feeling by stopping the blowing in that direction and to the rear of the smoker. The effects of smoke can be eliminated.

As shown in FIG. 12, the slits 3 having different widths are provided in the cylindrical body 31 rotatably arranged on the left and right of the front surface of the housing 1.
5 and 36 are formed to form slits 35 and 3 at symmetrical positions.
If only one of the openings 6 can be used as the air outlet 3, the air velocity of the air outlet can be adjusted depending on which slit 35, 36 is used as the air outlet 3. . Of course, even in this case, the wind direction can be adjusted by rotating the tubular body 31, and if the louvers 33 are arranged in the slits 35 and 36, the vertical wind direction can be adjusted. The wind from the blower fan 4 enters the inside of the cylinder 31 through the lower end opening of the cylinder 31 and is blown out from the blow-out port 3 which is the slits 35 and 36.

In the embodiments described above, the air sucked from the suction port 2 is sent to all the blowing ports 3 by the blower fan 4, but when the re-emission odor of the air cleaning filter 5 becomes a problem. As shown in FIG. 13, the suction port 20 may be provided on the back side of the housing 1, and the air sucked from the suction port 20 may be blown out from the left and right front blowing ports 3, 3. The air that has been sucked in through the suction port 2 and has passed through the air cleaning filter 5 is blown out only through the air outlets 3 on the upper surface side, and the air cleaning filter 5 through the left and right front air outlets 3, 3.
The wind that has not passed through is blown out.

At this time, if a cross flow fan whose axial direction is the left-right direction is used as the blower fan 4 and the outlets 3 are partitioned by a partition plate 16, a single blower fan 4 sucks in the air. It is possible to blow air from the mouth 2 to the blow-out port 3 on the upper surface and blow air from the suction port 20 to the blow-out ports 3 on the left and right sides of the front surface. In particular, the cross flow fan itself, which is the blower fan 4, is also shown in FIG.
As shown in FIG. 7, if a partition wall 40 that blocks the air flow in the axial direction is provided at the same position as the partition plate 16, the two types of air flows will not mix, and It is possible to more reliably prevent the re-emitted odor of the cleaning filter 5 from being mixed with the airflow blown out from the left and right outlets 3.

To increase the suction force of the air from the suction port 2, it is effective to arrange a plurality of blower fans 4 in the left-right direction so as to give different rotation speeds to each blower fan 4, as shown in FIG. is there. The air flow generated by the air velocities v1, v2, v3 of the air sucked from the suction port in the left-right direction makes the air flow into the suction port 2 efficient. Even if the blower fan 4 is single, the suction force at the suction port 2 can be made different in the left-right direction due to the pressure loss difference of the filter 5 and the pressure loss difference of the air blowing path.

The embodiment shown in FIGS. 16 to 19 is a case 1 in which a blower fan 4 which is a cross flow fan is housed in the lower portion.
A horizontally elongated suction port 2 on the upper front side of the front side, and blown air outlets 3 and 3 made of slits formed in a rotatable tube body 31 having louvers 33 on the left and right sides of the front side to the rear side of the rear side of the housing 1. A blowout port 3 for upward blowing is provided on the upper surface of the protruding bulging portion 10, and a suction port 20 is further provided on the back surface of the bulging portion 10. The blower fan 4 has a suction port 2 on the upper front side. The air that has been sucked in through the filter 5 and that has passed through the filter 5 is discharged from the blow-out port 3 on the upper surface of the rear part, and the air that has been sucked in from the suction port 20 on the back side is discharged from the blow-out ports 3 and 3 having the left and right wind direction adjusting functions.
Adjustment of the wind direction in the left-right direction of the left and right outlets 3 is performed by the cylindrical body 31.
This is done by operating the knob 38 provided on the. When the knob 38 is operated to the outermost position, the slit provided in the tubular body 31 is hidden in the housing 1, so that the air outlet 3 is closed. The knob 38 provided on the cylindrical body 31 is
Since it projects to the outside through the long hole 16 provided in the housing 1, the operation range is limited to the range of the long hole 16. In other words, the knob 38 also functions as a stopper that limits the range of rotation of the tubular body 31, and the knob 38 also makes the wind direction adjustment range clear to the user.

The hood 25 shown in FIG. 16 is detachably attached to the suction port 2 on the upper front surface of the housing 1 by hooks 26, 26 provided at both left and right ends. By controlling the suction from above, as shown in the figure, the attraction of cigarette smoke on the desk is made more reliable. Blow-out port 3 on the rear upper surface of the housing 1
Is provided on the upper surface of the bulging portion 10 provided on the back surface of the housing 1 as described above. The bulging portion 10 has a lateral width smaller than that of the housing 1 and a height of the housing 1. It is lower, and the air blown from the outlet 3 flows upward along the upper back surface of the housing 1. Since the air outlet 3 is lowered, a part of the housing 1 can be used as an airflow direction adjusting plate. Further, as shown in FIG. 17, if a wind direction adjusting plate 39 that rises from the back side of the upper end of the bulging portion 10 is provided, it is possible to further increase the directivity of the wind blown upward. This wind direction adjustment plate 39
May be fixedly arranged, but if the upper end rear surface side of the bulging portion 10 is rotatable frontward, the outlet 3 can be covered with the wind direction adjusting plate 39 when not in use. In addition, it is possible to prevent dust from entering the housing 1, and even if it is not used for a long period of time and is used for the first time in a long time, the dust is not rolled up from the blowout port 3. The wind direction adjusting plate 39 may be manually opened and closed, but it is desirable that the air direction adjusting plate 39 be automatically opened and closed by electric or wind pressure in conjunction with the operation of the blower fan 4.

Further, regarding the suction port 20 on the back side,
The suction port 20 runs in the left-right direction on the back surface of the bulging portion 10 and is provided at the back of the groove 11 where both ends reach both side surfaces of the bulging portion 10. Even when the back surface of the bulging portion 10 is brought into close contact with a wall, a partition, or the like, air flows through the groove 11 to the suction port 20, so that the function of the suction port 20 is not impaired. The effect can be expected if the depth of the groove 11 is 1 mm, but it is needless to say that the depth is deeper, and as shown in FIG. It may be provided as an opening on both the left and right side surfaces. In this case, the suction port 2 when installed close to the wall surface, etc.
There is less resistance to air flow to zero.

A cover 27 as shown in FIG. 21 (a) or FIG. 21 (b) is attached to the suction port 20 by using a hook 28 so that it cannot be installed in close contact with a wall or the like. This may prevent the suction from the suction port 20 from being obstructed. As shown in the figure, the cover 27 preferably has a downward opening. In addition to reducing the intrusion of dust from the suction port 20, even if the suction port 20 is contaminated with dust,
Since the cover 27 hides the suction port 20, it is possible to eliminate unpleasantness due to dirt when the housing 1 is viewed from the back. The cover 27 shown in FIG. 21 (b) is provided with a filter 29 for preventing dust from entering the housing 1 at a position on the suction port 20 side.

By the way, this air blower (purifier) is
It is intended to prevent smokers from spreading the smoke, and therefore it is assumed that the person instructing to drive is not the smoker in front of the smoker but another non-smoker. Therefore, as shown in FIG. 22, the operation switch S is provided on the front surface of the housing 1.
Not only the W and the operation display lamp 61 are provided, but the operation device 7 connected by wireless or wire is additionally provided, and the operation switch SW and the operation display lamp 6 are also provided in the operation device 7.
It is preferable to provide 1. Reference numeral 71 in the figure is a clip for fixing the operating device 7 to a telephone stand or the like. In addition, a display unit 8 for displaying the degree of contamination of the air cleaning filter 5
23 is installed on the front surface, the left and right side surfaces, and the back surface of the housing 1, respectively, as shown in FIG. 23, the contamination degree of the filter 5 can be checked from each direction as shown in FIG. In the figure, D is a desk.

In a wide area such as an office and where ventilation such as air conditioning is provided, it is sufficient that the air blower (cleaner) operates only during smoking.
However, in a narrow space such as a home, if smoking is started because smoking has started, it is preferable that continuous operation is performed at a low speed even after a lapse of a predetermined time. Figure 2
5 and FIG. 26 are in view of this point. When the switch SW is pressed once, the motor 40 of the blower fan 4 is energized by the H level output of the counter C through the timer T and the transistor Q ₁ . When the timer T times up (the time limit is about the time required for one cigarette), the transistor Q ₁ is turned off, but when the changeover switch S is on the contact A side, that is, it is set for home use. , The transistor Q ₂ is turned off after the transistor Q ₁ is turned off.
Is turned on, and the motor 40 continues to operate at low speed via the voltage dividing resistor R. However, when the changeover switch S is on the contact B side (office side), the operation ends with the time-up of the timer T. In this case, switch SW
Press twice twice for continuous operation, and switch SW
You can stop by pressing.

[0032]

As described above, according to the present invention, the air blown from the air outlets provided on the front left and right sides and the upper surface side of the housing constitutes an air curtain, and the smoke of the cigarette is diffused by the disturbance air flow. In addition to preventing the above, the smoke is surely sucked from the suction port, and the nuisance caused by the smoke can be prevented.

If an air purifying filter through which the air flow from the suction port to the air outlet passes is provided,
It also functions as an air purifier that captures the smoke particles of cigarettes, and if a hood is provided at the front suction port, the smoke of cigarettes can be sent to the suction port more smoothly. It is effective to set the front suction port at the upper part of the front of the case to capture the sidestream smoke rising from the cigarette. Especially, if the suction wind velocity of the front suction port is 1.0 m / sec or more, The smoke, especially sidestream smoke, can be put on the suction wind and reliably and smoothly sent to the suction port, and the smoke suction efficiency is improved. It is desirable that the wind speed ratio between the suction wind speed of the front suction port and the blowing wind speed of the left and right blowing ports is 1: 1 to 4. If it deviates from this range, the efficiency of sucking in the smoke will be deteriorated, and the smoke will rather be diffused by the blowing air.

Further, if the air outlets on the left and right of the front face extend over substantially the entire length of the casing in the vertical direction, the left and right air curtains can be formed more reliably. The left and right front air outlets should be located at a distance from the air inlets that is a predetermined distance determined by the relationship between the air velocity at the air inlets and the air velocity at the air outlets. It is preferable in order to avoid mutual interference between the airflow and the blowing air.

Further, the front left and right air outlets can freely adjust the left and right wind directions and the up and down wind directions, can freely stop the air blowing, and can be provided with a wind speed adjusting means to form an air curtain according to the installation situation. Therefore, smoke diffusion can be prevented more reliably. When the left and right air outlets can be adjusted in the left and right wind directions, the adjustment angle is approximately 90 ° from the front to the side of the housing.
It is preferable that the wind direction is adjusted, and if the operation section for adjusting the wind direction and the knob for setting the wind direction adjusting range are provided, the wind direction can be easily adjusted and the adjustable range becomes clear. It has excellent usability.

The blow-out port on the upper surface side is provided closer to the rear part of the housing, or is arranged at a position lower than the suction port on the front surface, so that the mutual influence with the air flow sucked into the suction port on the front surface can be reduced. As a result, both the formation of an air curtain that acts as a barrier and the suction of smoke can be performed accurately, and especially when it is provided on the rear side of the housing and on the upper surface of the lowered portion, the rear rear surface of the housing is removed. Since it can be used for wind direction adjustment, it is more effective.

A guide for spreading the blowout airflow to the left and right is provided at the topside blowout port, an airflow direction adjusting plate for controlling the blowout direction is provided, or the airflow inside the housing from the blower means to the topside blowout port. Even if the path is long in the vertical direction along the back plate of the housing, it is advantageous for forming the air curtain and the effect can be enhanced. When the airflow direction adjusting plate is provided, it may also be used as a cover for closing the blowout port on the upper surface of the housing. It is possible to prevent dust from entering through the upper surface outlet when not in use.

The provision of means for varying the wind speed of the air sucked from the suction port in the left and right directions also effectively acts on the smoke suction. When a suction port that sucks in the air for blowing out from the left and right outlets is provided on the back side of the housing, problems relating to the re-emission odor of the filter can be reduced, and a more preferable one can be obtained. At this time, a single air blowing means consisting of a cross flow fan whose axial direction is the left-right direction is used to blow air from the front inlet to the upper outlet and from the rear inlet to the left and right outlets. However, even if two types of air flows can be obtained, it is advantageous in terms of cost because a single blowing means is required.

The suction port on the back side is provided on the back side of the housing, and the end portion is provided in a groove reaching the side surface of the housing, or is also opened on the side surface of the housing, or protrudes backward. If you install a cover that attaches to the wall, you can secure the suction from the suction port on the back side even when the back side is closely attached to the wall etc. You will always get it.

Further, by providing a display section for displaying the degree of dirt of the filter on each surface of the housing, it is convenient because the dirt of the filter can be confirmed from each direction, and the operation section for driving instructions is further provided. By providing the main body and the operating device remote from the main body, the operability is excellent.
