[0003]

The above-mentioned counter a with an air purifying function is extremely convenient in that smokers and smokers do not feel any discomfort even if they are adjacent to each other. is there. However, in order to prevent the smoker and the smoker from feeling discomfort to each other even if they are adjacent to each other, the counter a with an air purifying function must be provided immediately so that the smoke discharged from the smoker does not go to the smoker. Therefore, the air volume of the blower e must be relatively large. Accordingly, the capacity of the net g, the electric precipitator f, and the deodorizing filter h must be selected in accordance with the air volume of the blower e. In this case, the counter a with the air purifying function must be large and expensive. Furthermore, since the air precipitator i includes the electric dust collector f, maintenance is also required. Therefore, in order to easily use the counter a with the air purifying function, it is inconvenient in terms of its price, size and maintenance in order to be easily used in a rest area such as a factory.

Accordingly, the present invention has been made in view of the above circumstances, and provides a counter with an air purifying function which is small in size, can be easily maintained, is low in price, and is convenient for simple use. The task is to

[0005]

According to a first aspect of the present invention, at least one or more air suction ports and at least one or more air discharge ports are provided in a counter body. In a counter with an air purifying function in which a blower and an air purifying device are housed in the counter main body located between the air discharging port, the air purifying device adopts a mechanical filter, and a top plate forming a counter main body An air suction port is opened, a drain groove is provided on a top plate located around the air suction port, and a suction guard having a ventilation hole is fitted into the drain groove. Therefore, according to this feature, after the mechanical filter has reached the end of its service life after a certain period of use, it may be replaced when the life of the mechanical filter has come, and even if the liquid overflows from the container placed on the top plate, the suction guard and the drain groove into which the suction guard is fitted. As a result, liquid does not enter the counter body from the air suction port.

The invention according to a second aspect is characterized in that a draining surface closely contacting the side surface of the drainage groove and the upper surface of the top plate connected thereto is formed below the suction guard. Therefore, according to this feature, since the draining surface of the lower part of the suction guard is in close contact with the upper surface of the top plate and the side surface of the draining groove, even the liquid does not enter the draining groove.

According to a third aspect of the present invention, the air vent of the suction guard is located at a position higher than an ashtray placed on the top plate. Therefore, according to this feature, it is difficult for the sparks of cigarettes placed in the ashtray to enter through the ventilation opening of the suction guard.

According to a fourth aspect of the present invention, the suction guard has an apex which is substantially similar in shape to the air suction port and is substantially horizontal when installed on the top plate, and has an outer dimension (l ₁ ) of the apex. The ratio (l ₁ /) to the inner diameter (l ₂ ) of the air suction port
l ₂ ) ranges from 1.1 to 1.2. Therefore, according to this feature, the size of the Amagasa is not so large as compared with the size of the air suction port, so that smoke above the Amagasa can be easily sucked.

[0009] The invention of claim 5 is characterized in that a fitting hole is opened in the Amagasa and an ashtray is fitted in the fitting hole. Therefore, according to this feature, it is less likely that there is no ashtray, and even if it is placed in an ashtray and smoked, smoke is directly sucked.

According to a sixth aspect of the present invention, in the mechanical filter, the electrostatic filter and the deodorizing filter are overlapped and folded in a waveform, and the waveform is processed so that the intervals between peaks and valleys are substantially equal to each other and fixed to the outer frame. It is characterized by becoming.
Therefore, according to this feature, since the filtration area of the mechanical filter can be widened and the air can pass through the mechanical filter on average, the pressure loss is small, and the suspended matter and odor are efficiently removed.

According to a seventh aspect of the present invention, a pre-filter is provided on the upstream side of the mechanical filter, and the pre-filter is detachably provided at the air suction port, and the two nets are integrally formed at a predetermined interval. It is characterized by becoming. Therefore, according to this feature, even if the cigarette sparks and the sparks reach the air suction port through the suction guard, they hit the first mesh to stop the sparks and the sparks, or the sparks that became finer due to the impact at that time. Even if the fire passes through the first mesh, it again strikes the next mesh at a certain interval, at which point the sparks and the fire itself burn out, lose heat and extinguish the fire.

The invention according to claim 8 is characterized in that the blower can be operated when the pre-filter is attached to a fixed position of the air suction port. Therefore, according to this feature, the blower cannot be operated unless the pre-filter is attached to the fixed position of the air suction port.Therefore, the sparks, fire types, and other foreign substances of cigarettes enter the counter body through the suction guard. I will not enter.

FIG. 1 is a block diagram showing an embodiment of the present invention.
This will be described in detail based on −14. FIG. 1 is a perspective view of a counter with an air cleaning function according to an embodiment of the present invention, FIG. 2 is a sectional view taken along line AA in FIG. 1, and FIG. 3 is an assembly view of the counter with an air cleaning function. The counter 1 with an air purifying function shown in the figure is the most basic form at present, and is generally called a double top plate (which is derived from the presence of the top plate 8 and the Amagasa 14 described in detail later). 2 has at least one or more air suction ports 3 and at least one or more air discharge ports 4, and a blower 5 and an air cleaning device 6 are provided in a counter body 2 located between the air suction ports 3 and the air discharge ports 4. The air purifying apparatus 6 employs a mechanical filter 7 and opens the above-described air suction port 3 on a top plate 8 constituting the counter body 2, and a top plate located around the air suction port 3. 8 is provided with a drain groove 9 into which a suction guard 11 having a vent 10 is fitted.

The counter body 2 comprises the top plate 8 made of a flat plate having a certain thickness, and a box body 12 attached to and supported on the lower surface of the top plate 8. The air suction port 3 of the top plate 8 is covered with a suction guard 11 so that cigarette butts, sparks, fire, ash, liquid, and other dusts do not easily enter the counter body 2. The suction guard 11 includes a side plate 13 having a ventilation port 10 and an apex 14 supported on the side plate 13 at a predetermined interval in parallel with the top plate 8 above the air suction port 3. As shown in FIG. 4, the lower part of the side plate 13 of the suction guard 11 has an L-shaped draining surface 1 that is in close contact with the upper surface 8 a of the top plate 8 and the side surface 9 a of the draining groove 9.
5 is formed. For this reason, even if a liquid such as juice overflows on the top plate 8 outside the suction guard 11, the L
Since the surface 8a and the side surface 9a of the drain groove 9 and the drain surface 15 of the suction guard 11 are in close contact with each other, the liquid does not pass through the gap between them, and even if it passes through, the liquid of the volume of the drain groove 9 can be stored. It can be said that almost no liquid enters the inside of the counter body 2 through the air suction port 3.

The vent 10 provided in the side plate 13 of the suction guard 11 is located at a position (h ₂ ) higher than the height (h ₁ ) of the ashtray 16 placed on the top plate 8, for example, h ₂ = 3-4
cm. That is, the height of the ashtray 16 _{(h 1)} is the infinite variety by individual _ashtray, because those within h 1 = 3-4 cm is most installation height of the vent 10 _{(h 2} ) Is 3-4cm or more, most of the ashtray 1
6 higher. Therefore, even when cigarettes are placed in the ashtray 16 or in the process of dropping ash on the ashtray 16, the sparks and the fire fall through the ventilation port 10, and the sparks and the fire are passed through the air suction port 3 and countered. The possibility of entering the inside of the main body 2 is very low.

As shown in FIG. 5, the Amagasa 14 is substantially similar in shape to the air suction port 3.
Dimensions (l ₁ ) and inner diameter dimension (l ₂ ) of air suction port 3
Ratio of _(l 1 / l ₂₎ is from 1.1 to 1.2. Therefore, compared to the case where the ratio (l ₁ / l ₂ ) of the Amagasa 14 is 1.4 or 1.5 as compared with the air suction port 3 as in the conventional example, the smoke floating on or above the Amagasa 14 Can be quickly sucked. In addition, in FIG. 5, although the Amagasa 14 is square, it may be circular or other polygons, and there is no particular limitation.

As a result of the above, the counter 1 with the air cleaning function
As shown in FIG. 6, the ashtray 16 can be set on the Amagasa 14. That is, a fitting hole 20 corresponding to the size of a desired ashtray is opened in the Amagasa 14, and the ashtray 16 may be fitted into the fitting hole 20.

The air purifying device 6 housed in the counter body 2 purifies contaminated air such as tobacco smoke entering the smoke separating machine body 2 through the air suction port 3. Pre-filter 21 for removing relatively large particles
And a mechanical filter 7 for removing fine particles and odor after passing through the pre-filter 21. This mechanical filter 7 is a composite of an electrostatic filter 22 and a deodorizing filter 23, as shown in FIG. The electrostatic filter 22 is made of a natural fiber such as paper pulp, cotton, wool, silk or the like, or a woven or non-woven fabric of a synthetic fiber, which is sufficiently air-permeable, and is subjected to a charge treatment. The deodorizing filter 23 is made of the same material as that of the electrostatic filter 22 and includes a material that absorbs odor.

The mechanical filter 7 overlaps the electrostatic filter 22 and the deodorizing filter 23 with a waveform 2
4, the peaks 24a of the waveform 24 and the valleys 24b
The bead processing is performed so that the intervals between them are substantially the same, and the beads are fixed to the outer frame 25. In this bead processing, even if the waveform 24 of the mechanical filter 7 is fixed to the same by the outer frame 25, the waveform 24 at the end fixed to the outer frame 25 becomes the same, but the waveform 24 away from the end is air. Because it is disturbed by the passage of That is, in this bead processing, the plurality of bars 26 are
a at a right angle, and a method of bonding. Therefore, the filtering area of the mechanical filter 7 can be widened by the waveform 24, and the air can be averagely passed through the mechanical filter 7 by the bead processing, so that the pressure loss is small and the odor together with the suspended matter is efficiently removed. I can do it.

On the other hand, as shown in FIG. 10, the pre-filter 21 is naturally located on the upstream side of the mechanical filter 7, is provided in the air suction port 3 in a detachable manner, and is provided with two net-like objects 27, for example. The meshes having a mesh size of 24 mesh are integrally formed at regular intervals. Upstream net 2
7a and the downstream mesh 27b are both housed in the frame 28,
While the upstream mesh 27a is supported by the support bar 29, the downstream mesh 27b is simply supported by the frame 28. In this way, even if the sparks or the kind of cigarette of the cigarette reaches the air suction port 3 through the suction guard 11 and further passes through the upstream mesh 27a, it hits the downstream mesh 27b at a certain interval, and at that time. The sparks and the fire itself burned out, losing heat and extinguishing the fire. here,
The reason that the upstream net-like material 27a and the downstream net-like material 27b are not placed one on top of the other is only a single mesh with a fine opening, and that the material passing through this mesh cannot be treated. This is because it would be better to install a single mesh with fine openings.

Such a pre-filter 21 must always be set in the air suction port 3 while the counter 1 with the air cleaning function is in operation, and therefore, the limit switch 30 (see FIG. When the pre-filter 21 is set in the air suction port 3, the limit switch 30 is turned on, and if not, the blower 5 is not operated.

Further, a mesh 31 as shown in FIG. 3, for example, having a mesh size of 24 mesh, is a suction guard 1.
1 and the pre-filter 21. Therefore, if the mesh material 31 is provided, a large floating substance such as a spark of a cigarette or a fire that has passed through the suction guard 11 can be stopped in front of the pre-filter 21, and the safety is further enhanced.

The blower 5 is mounted on a trapezoidal mount 32 (see FIG. 2) when viewed from the side.
Is attached to the air exhaust port 4 of the counter body 2, and the mount 32 maintains the strength of the lower part of the counter body 2. Then, a leg 33 is provided on the lower surface of the counter body 2.
And casters 34 are attached to the ends thereof.

In the embodiment shown in FIGS.
The top plate 8 is square, and the suction guard 11 and the air suction port 3 are also square, but are rotated by 45 degrees with respect to the suction guard 11 and the air suction port 3. This allows
A space 8 convenient for placing an ashtray or the like between the side plate 13 corresponding to the side of the suction guard 11 and the corner 8b of the top plate 8.
As a result, the ashtray 16 is placed in the space 8c, so that the smoke of the tobacco can be easily sucked from the vent 10 provided in the suction guard 11. In addition, 35 in FIGS. 1 and 6 is an operation switch, and 36 in FIG. 3 is a rear door.

Next, the use state of the counter 1 with an air purifying function having the above-mentioned configuration will be described. First, operation switch 3
Turn on 5 and blower 5 of counter 1 with air purifying function
When the power is turned on, the presence of the pre-filter 21 is confirmed by the limit switch 30, and the blower 5 is operated. When the blower 5 is in a steady operation, the counter 1 with the air cleaning function
A streamline leading to the air suction port 3 is generated on the top plate 8 and in the vicinity thereof, and the smoke of the cigarette immediately passes through the suction guard 11 together with the surrounding air, further passes through the mesh material 31, and the air suction port 3 Reach At this time, of course, the cigarette butts are prevented by the suction guard 11 from entering until it reaches other foreign matters, sparks, fire, ash, liquid, and the like. Those that have passed through the suction guard 11 are stopped by the net 31. Further, the air is sucked into the counter main body 2 through the pre-filter 21 provided in the air suction port 3, and relatively large particles contained in the air are removed by the pre-filter 21. At this time, since the pre-filter 21 has a double structure, most of the above-mentioned components stop here. Then, fine particles such as smoke are captured by the electrostatic filter 22 of the mechanical filter 7, and odor components such as gas are removed by the deodorizing filter 23, and the air becomes clean air. Thereafter, clean air is discharged from the air discharge port 4 to the outside. In such a situation, an ashtray is naturally required, so the ashtray 16 is placed on the top plate 8, or the ashtray 16 is placed on or attached to the Amagasa 14. Smoke floating on the ashtray 16 on the Amagasa 14 is also directly sucked into the counter body 2 and purified. Since the life of the mechanical filter 7 is extended by use, the mechanical filter 7 is replaced with a new one at that time. The pre-filter 21 and the net 31 are returned to the original state by simple washing.

FIGS. 11 and 12 show another embodiment of the present invention. FIG.
There is an ashtray 16 in the Amagasa 14 and the difference between these counters 1a with air purifying function and the embodiment of FIGS.
The point is that the top plate 8 is rotated by 45 degrees. Other configurations and operations are the same as those of the embodiment of FIGS.

[0029]

As described in detail above, the counter having an air purifying function of the present invention has the following effects.
The invention according to claim 1 is such that after the mechanical filter has reached the end of its life after being used for a certain period of time, it is sufficient to replace the mechanical filter, and even if the liquid overflows from the container placed on the top plate, the suction guard and the drainer into which the suction guard is fitted. The groove prevents liquid from entering the counter body through the air suction port. Therefore, since the mechanical filter is used, the structure can be simplified and the size can be reduced, the maintenance can be simplified, and it is convenient to use easily at a low cost.

According to the second aspect of the present invention, since the draining surface of the lower part of the suction guard is in close contact with the upper surface of the top plate and the side surface of the draining groove, no liquid enters the draining groove. Therefore, in addition to the above effects, there is almost no possibility that the liquid enters the counter main body, so that it is possible to ensure the thoroughness.

According to the third aspect of the present invention, it is difficult for the sparks of cigarettes placed in the ashtray to enter through the ventilation opening of the suction guard. Therefore, in addition to the effects described above, the mechanical filter is hardly damaged by the sparks of cigarettes.

According to the fourth aspect of the present invention, the size of the Amagasa is not so large as compared with the size of the air suction port, so that smoke above the Amagasa can be easily sucked. Therefore, even if a person is standing and smoking a cigarette, the smoke on the Amagasa is efficiently sucked.

According to the fifth aspect of the present invention, the absence of an ashtray is reduced, and smoke is directly sucked in even when placed on an ashtray and smoked. Therefore, the area around the counter with air purification function is less likely to be stained with cigarette butts and ash,
Efficiently inhales cigarette smoke.

According to the sixth aspect of the present invention, the filtration area of the mechanical filter can be made large and the air can pass through the mechanical filter on average, so that the pressure loss is small and
Efficiently remove suspended matter and odor. Accordingly, the size of the mechanical filter and the blower can be reduced, and as a result, the size of the counter body for storing the mechanical filter and the blower can be reduced.

According to the seventh aspect of the present invention, even if the cigarette sparks or fire reaches the air suction port through the suction guard, the cigarette strikes the first mesh to stop the sparks or the fire, or the shrinkage due to the impact at that time. Even if the sparks or the fire passes through the first mesh, it again strikes the next mesh at a certain interval, at which point the sparks and the fire themselves burn out, lose heat and extinguish the fire. Accordingly, damage to the mechanical filter due to sparks or fire and other adverse effects can be minimized.

According to the present invention, since the blower does not operate unless the pre-filter is attached to the fixed position of the air suction port, the sparks, the fire type, and other foreign matters of the cigarette enter the counter body through the suction guard. There is nothing. Therefore, damage to the mechanical filter and other adverse effects due to the incorporation of sparks, fire, and other foreign substances due to forgetting to attach the pre-filter or occurrence of deviation from the home position can be minimized.

According to the ninth aspect of the present invention, it is possible to stop a spark, a fire type, a large floating substance, and the like of a cigarette by using a suction guard-shaped mesh before the pre-filter. Therefore, damage to the mechanical filter and other adverse effects due to sparks and fire can be more completely suppressed.
