Subsequently, a spraying device 2 for performing an air cleaning process
Will be described. The spray device 2 is disposed below the intake duct 22 and above the water pool 28, and
A cylindrical water spray rotator 4 having an open bottom as shown in FIG.
1, a water receiving groove (liquid receiving part) 42 provided at a lower end inside the water spray rotating body 41, and a water discharge port (discharge part) 44 of a water supply pipe 43.

In the spray device 2, water jetted from a water discharge port 44 flows out in an outer peripheral direction by two upper and lower water outlet guides 45 and 46, and a small hole (ejection hole) 51 of a rotating water spray rotating body 41. Is supplied to supply and outflow mist water for purifying air into the intake duct 22. The periphery of the spray device 2 is a steam-water mixing unit that mixes the air sucked from the outside with the sprayed air.

On the outer peripheral surface of the water spray rotating body 41, a number of small holes 51 are formed for jetting water for purifying air.
The small hole 51 is hollowed out in a conical shape so as to promote the diffusion of the spray water, so that the large diameter portion is located on the outer surface side and the small diameter portion is located on the inner surface side.

A water receiving groove 42 is formed on the inner lower end of the water spray rotating body 41 over the entire circumference. The water receiving groove 42 is for temporarily storing water jetted from the water discharge port 44 before spraying.

A column 52 is projected downward from the center of the inside of the upper surface of the water spray rotating body 41, and the column 52 is inserted and fixed to the shaft 33. This water spray rotating body 4
1 is rotationally driven by a motor 5 (FIG. 1).

A water discharge port 44 of a water pipe 43 is provided inside the water spray rotating body 41. This water pipe 43 is used for the tank 3
A shaft 33 that is rotatably driven is disposed at the center inside the water pipe 43. The water pipe 43 is inserted into the water reservoir 28 (FIG. 1), and does not rotate even if the shaft 33 rotates.

A circular thin plate-shaped upper water outflow guide 45 is horizontally mounted at the lower end of the cylindrical portion 52 of the water spray rotating body 41 and opposed to the water discharge port 44. Most of the water spouted upward from the water discharge port 44 is supplied to the upper water outflow guide 45.
And fall.

Below the upper water outflow guide 45, a lower water outflow guide 46 also having a circular thin plate shape is provided integrally with the water supply pipe 43. A round hole corresponding to the outlet 44 is provided. The lower water outflow guide 46 prevents water dropped on the upper water outflow guide 45 from being transmitted to the water pipe 43 without being supplied to the water receiving groove 42.

Thus, the water jetted from the water discharge port 44 is uniformly supplied to the water receiving groove 42 all around.

In this spray device 2, the water jetted from the water discharge port 44 is used as a water outlet guide 45, 46 as shown in FIG.
As a result, it falls into the water receiving groove 42. This water rises along the inner wall surface by the rotating force of the rotating water spray rotating body 41,
The water is sprayed outward from the small holes 51 as mist-like water (fine water droplets) by centrifugal force. In addition, the water spray rotating body 41 has a structure in which the shaft 33 can be separated to facilitate maintenance. The structure of the shaft 33 is shown in FIG.

In the air purifying apparatus 1 having such a fin-shaped projecting wall 14, the water spray rotating body 41 as shown in FIG.
Water coming from the tangential direction of the fin 14B collides at right angles to the receiving surface of the fin 14B. Therefore, the amount of water flowing in the lateral direction of the receiving surface of the fin 14B can be reduced as compared with the case where water collides only along the inner wall of the spray device 2.

As a result, the water can be made finer efficiently, and the water can be further atomized. Then, when dirty air is passed through the spray device 2, the chance (probability) of even fine dust coming into contact with the water filter increases, so that both large dust and fine dust can be removed. The cleaning efficiency can be improved.

Next, a description will be given of the porous cylindrical body 15 for atomizing water by another method. In this air cleaning device 1, a tubular body 15 with a hole as shown in FIG. 6 is provided.

And a plurality of small holes 15 punched (opened) to the cylindrical body 15A to a diameter of about 1 mm.
B.

The height h of the porous body 15 is substantially the same as the height of the water spray rotating body 41. In addition to aluminum, a corrosion-resistant metal plate such as 18
-8 stainless steel processed into a bottomless basket shape may be used.

In the air purifying apparatus 1 having such a tubular body 15 with perforations, as shown in FIG.
First, water spouted from the tangential direction is radially diffused by passing through the small holes 15B of the perforated cylindrical body 15, and further finely divided water diffused from the perforated cylindrical body 15 is diffused. By colliding with the first vertical partition plate 27 or the like of the spraying device 2, fine mist-like water droplets are generated. The water filter 15 </ b> C is constituted by the mist-like fine water particles.

Therefore, when dirty air is passed through the spraying device 2, the chances of even fine dust coming into contact with the water filter 15C are increased, so that both large and fine dust can be removed. The cleaning efficiency can be improved.

When the tank 3 is mounted as shown in FIG. 1, the pump device 6 is inserted into the tank 3, and the lower pump 34 is submerged in water. This is for the following reason. For example, if the pumps 34 and 35 are arranged in the air and water is delivered only when used, the water must be sucked by discharging the air when the pumps 34 and 35 start rotating. However, if the pump 34 is already immersed in water at the time of stoppage as in the present embodiment, water can be supplied without discharging air, so that a highly airtight pump is not required, and inexpensive and durable. A highly efficient pump can be used.

Returning to FIG. 11, at the center of the pump partition plate 113, a cylindrical portion 116 is provided upright, and the shaft 33 is rotatably inserted and supported here. This column part 1

The liquid transfer mechanism 9 includes a water pool 28 for collecting water from the spray device 2 and an annular drainage channel 121 for guiding water from the water pool 28 to the tank 3.

The water pool portion 28 is formed in a concave dish shape and is arranged below the spraying device 2. Here, the periphery of the water supply pipe 43 is slightly swelled and formed in a substantially conical shape so that water can be reliably collected.

The water reservoir 28 has a water receiving / draining port 12
2 are provided to communicate with the annular drainage channel 121.
Although not shown, the water collecting portion 28 is slightly inclined as a whole so that the area around the water receiving / draining port 122 becomes lowest so that water collects in the water receiving / draining port 122.

The annular drainage channel 121 forms a path extending substantially one round from the water receiving drainage port 122 to the main body drainage port 123.
The annular drainage channel 121 is a gentle slope such that it becomes lower as it is closer to the main body drainage port 123, and water is guided to the tank 3 by this slope. An outlet valve 131 is provided in the main body outlet 123, and is opened by the pressing boss 66 of the tank 3 when the tank 3 is mounted on the cabinet 21.

The operation of the air cleaning device 1 configured as described above will be described below. In FIG. 1, when the power is turned on and the start of the air cleaning process is instructed, the fan 4, the spraying device 2 and the pumps 34 and 3 are driven by the motor 5.
5 is driven to rotate. A suction force is generated by the rotating fan 4, and external air is drawn in from the air inlet 11.

The fan 4 also has a function of generating a forced air circulation route to the inside and outside of the air purifying device 1.
It is possible to promote indoor air purification and purify a wide range of indoor air.

On the other hand, pumping from the tank 3 is started by the pumps 34 and 35 of the pump device 6 which is driven to rotate.
Water is sent to the spray device 2 through the water pipe 43. As shown in FIG. 3, this water spouts from a water discharge port 44 of the water pipe 43. The jetted water strikes the upper water outflow guide 45 and falls on the lower water outflow guide 46. This water is supplied to the water outlet 44
Into the lower water outflow guide 46
From the outer edge of the outer periphery.

Most of the water that has flowed down falls into a water receiving groove 42 inside a water spray rotating body 41 that rotates at a high speed. The water temporarily stored in the water receiving groove 42 rises along the inner wall surface due to the rotating force of the water spray rotating body 41 and jets outward from the small hole 51.

As shown in FIG. 2, water passes through the small holes 51 of the water spray rotator 41 to be finely divided into a number of fine particles, and is further refined by the fin-shaped projecting wall 14 described with reference to FIG. Then, the periphery of the spray device 2 is filled with mist-like water, and this serves as a steam-water mixing unit.

Accordingly, dust and odor components contained in the inhaled air are adsorbed and collected by the atomized water.
By subdividing and flowing water in this way, the contact area between air and water can be increased, dust and the like can be easily adsorbed to water droplets, and the air cleaning efficiency can be improved.

In the spray device 2, the water spray rotating body 4
Since the water flows out using the rotation force of 1, the pump 3 is used in comparison with the case where the water is directly sprayed by the pumping power of the pump.
Sufficient spraying can be performed even with a low water supply power of 4, 35 (FIG. 11). Therefore, an inexpensive pump can be used, and the cost can be reduced.

The air containing the water droplets reaches the lower pool 28 as it is. In the water pool part 28, the air turns its flow upward so as to flow into the exhaust duct 23. here,
Water droplets containing dust and dirt are dropped into the water pool portion 28, and water adhered to the inner wall surface around the spray device 2 is also removed from the water pool portion 2.
Add dropwise to 8. This removes dust and dirt contained in the air together with the separated water, thereby purifying the air.

The water accumulated in the water pool 28 flows into the annular drainage channel 121 from the water receiving drainage port 122, and is guided to the annular drainage channel 121 to reach the main body drainage port 123. From here, water is collected in the tank 3 through the tank inlet 65 of the tank 3, and is used again as water for air cleaning.

On the other hand, as shown in FIG. 15, the purified air rises in the exhaust duct 23 and is discharged outside from the exhaust port 12 by the fan 4. As described above, the air cleaning device 1 forcibly brings air and water into contact with each other and adsorbs dust in the air, so that the air can be cleaned efficiently with a simple configuration. Further, since the water returned from the spray device 2 can be efficiently collected in the tank 3, an air purifying device that effectively utilizes the water in the tank 3 can be provided.

Next, the cooling device for the motor 5 will be described. As shown in FIG. 1, in the air cleaning device 1, an air introduction part 16 is opened in the horizontal partition plate 30, and the air after cleaning obtained from the spray device 2 is guided to the motor 5. . For example, a part of the purified air obtained by the water filter 15 </ b> C described with reference to FIG. 7 is used for cooling the motor 5. Of course, all the air after cleaning may be guided to the motor 5 for cooling.

Since a part of the air that has been cleaned by the water filter 15C is guided to the motor 5, the motor 5 can be cooled by air having a temperature substantially equal to the temperature of the water. It can be cooled without adhering dust and the like. In particular, since the air that has passed through the water filter 15C is lower by about several degrees Celsius than room temperature, the cooling effect is higher than when the motor 5 is cooled by air at room temperature, and the cooling efficiency of the air cleaning device 1 can be improved. it can. Therefore, the life of the air cleaning device 1 can be extended, and the maintenance thereof can be reduced.

Although not shown in the figure, a fan is attached to the shaft of the motor 5 to take in the air after cleaning from the air introducing section 16 and exhaust the air after cooling the motor 5. Is also good.

FIG. 16 is a partial longitudinal sectional view of the air purifying apparatus 1 according to the present embodiment as viewed from the window 26 side. As shown in FIG. 16, in the air purifying apparatus 1, an inlet cover 11A is provided above a window 26 of the cabinet 21, and a transfer mechanism 7 with a tank attaching / detaching function is attached to the left and right below the window 26. ing.

The window 26 is provided for confirming the operation of the spray device 2. In the present embodiment, the user can observe the state of the water spray rotating body 41 through the window 26. A plurality of LEs are provided inside the window 26.
D <b> 25 is attached, and reflected light obtained by irradiating the spray device 2 with light is observed through the window 26. Whether the water filter 15C is formed by the spray device 2 can be directly visually confirmed from the reflected light.

When the water filter 15C is illuminated with light from the LED 25, the reflected light looks brilliant, so that the electric decoration effect of the air cleaning device 1 can be enhanced. A lens may be provided in the window 26, and the reflected light may be enlarged by the lens. This makes it easier to check the operation of the spray device 2.

A white light or the like is used as the light source in addition to the LED 25. In this case, by providing a color filter, for example, a blue filter, the blue light (specific wavelength light) transmitted through this filter is miniaturized. By irradiating the applied water, the lightning decoration effect can be further enhanced.

A lens having a lenticular surface or the like may be provided in the above-described white light or LED 25 to diffuse light generated from these light sources and irradiate the diffused light to fine water. When a filter is combined with the filter, the operation can be more easily checked, and the lighting effect can be enhanced.

Further, these light sources are provided with an optical element such as a diffraction grating having a plurality of slits to diffuse light generated from these light sources and irradiate the diffused light to fine water. Is also good. This can also enhance the lightning effect. If there is enough space in the window 26, a light conducting member such as an optical fiber may be provided, and the light generated by the light source may be directly guided to the miniaturized water via the optical fiber for irradiation. This can enhance the lightning effect.

Further, a control unit for blinking light may be provided, the light generated by the light source may be periodically blinked, and the blinking light may be irradiated on the miniaturized water. Thus, a strobe effect such as that water appears to stop depending on the blinking cycle is obtained, and the lightning effect can be further enhanced. Note that an ultraviolet lamp may be used as a light source, and the miniaturized water may be irradiated with ultraviolet light. Thereby, the sterilizing effect of the air after cleaning can be enhanced.

Next, the operation for attaching and detaching the tank 3 will be described. The water used in the spraying device 2 is reused while circulating as described above, but the water used for a long time becomes dirty and needs to be periodically disposed.

First, the tank 3 is removably attached to the lower part of the cabinet 21 together with the main substrate 100 by the transport mechanism 7 having a tank attaching / detaching function as shown in FIG. In the transport mechanism 7, the main body substrate 1 with the tank 3
Two fixed levers 81A and 81B having both functions of holding and detaching 00 are attached to both sides of the cabinet 21 in a freely rotatable manner.

The lower ends of the fixed levers 81A and 81B are bent inward to form claw-shaped locking portions 82A and 82B. On the other hand, locked portions 85A and 85B are provided on the side surface of the main body substrate 100 or the side surface of the tank 3,
Here, the locking portions 82A and 82B are locked, and the main body substrate 100 with the tank 3 is held. The tank 3 is held by tank locking portions 83A, 83B and the like protruding from the main body substrate 100.

The cabinet 21 is provided with handles 80A, 80B for gripping the main body on both sides thereof, and fixed levers 81A, 81B (not shown in FIG. 16) are provided below the handles 80A, 80B. Storage section 86 to store

For example, each of the storage portions 86A, 8 on both side surfaces
6B is provided with locking portions 87A and 87B having a ratchet mechanism for locking the fixing levers 81A and 81B. When the fixing levers 81A and 81B are repeatedly pressed against the cabinet 21, the locking portions 87A and 81B are pressed against the cabinet 21. Thus, a state in which each of the fixed levers 81A, 81B is locked and a state in which each of the fixed levers 81A, 81B is released from the cabinet 21 are repeated.

Each of the fixed levers 81A and 81B has a non-storage surface. When each of the fixed levers 81A and 81B is inserted into the storage portion 86A or 86B of the cabinet 21, the non-storage surface is set to the non-storage surface. The left and right fixed levers 81A and 81B are locked to the cabinet 21 so as to coincide with the peripheral surface of the cabinet 21. Thus, the fixed levers 81A, 8
1B, in a state where the tank 3 is held, the outer surface thereof coincides with the outer peripheral surface of the cabinet 21 to give a unified appearance. When each of the fixed levers 81A and 81B is pushed, it projects outside the cabinet 21.

Pressing portions 84A and 84B are provided on the upper portions of the fixed levers 81A and 81B so as to protrude inward. That is, the axes of the fixed levers 81A and 81B are arranged between the locking portions 82A and 82B and the pressing portions 84A and 84B. This means that the fixing levers 81A and 81B are rotated to release the locking by the locking portions 82A and 82B, and at the same time, the pressing portions 84A and 84B come into contact with the upper surfaces (pressed portions) of the tank locking portions 83A and 83B. In order to push this downward.

When the tank 3 is mounted on the cabinet 21, the pump device 6 is inserted into the pump insertion port 63 and is press-fitted into the press-fitting portion 64 (FIG. 10) inside the cylinder port 62. At the same time, the tank lid 71 is opened by being pressed by the lower end of the pump device 6.

Next, an operation of removing the main body substrate 100 with the tank 3 as shown in FIG. 18 from the state where the tank 3 is mounted on the cabinet 21 shown in FIG. 16 will be described. First, the fixing levers 81A and 81B are pushed inside the cabinet 21 to release the ratchet. By this release, the fixing levers 81A and 81B slightly protrude from the outer surface side of the cabinet 21 as shown in FIG. Thereafter, the locking portions 82A, 82B of the left and right fixed levers 81A, 81B are moved to the main body substrate 100 or the tank 3
From the locked parts 85A and 85B, and pull it upward.
The fixing levers 81A and 81B are rotated.

At this time, as shown in FIG.
A and 84B come into contact with the upper surfaces (pressed portions) of the tank locking portions 83A and 83B and press them downward. Thereby, the tank 3 is slightly pushed out from the lower surface opening 20.

At the same time, the pump device 6 on the cabinet 21 side, which has been press-fitted inside the cylinder opening 62 of the tank 3, is withdrawn. Further, the pressing boss 66 of the tank 3 shown in FIG. 10 is separated from the outlet valve 131, and the outlet valve 131 is in close contact with the main body drain port 123 to prevent leakage of water.

In this state, when the cabinet 21 is lifted by holding the fixing levers 81A and 81B and the main board 100 with the tank 3 is pulled downward, the pump device 6 is gradually separated from the pump insertion port 63. Along with this, the tank lid 7 which has been opened in contact with the tip of the pump device 6
1 is closed by the urging force of the spring 74.

When the tank 3 is pulled out from the lower opening 20 of the main body as shown in FIG.
Is completely removed from the pump insertion port 63. At this time, the pump insertion port 63 and the tank inflow port 65 are completely closed by the tank lid 71. Thus, the removal of the tank 3 is completed.

As described above, by simply lifting the fixing levers 81A and 81B, the locking of the tank 3 can be released and pushed out at the same time, so that the tank 3 can be easily removed.

When the pump device 6 is detached from the tank 3, the draining spatula as the press-fitting portion 64 comes into contact with the outer peripheral surface of the pump device 6, and the attached water is removed.
Water does not drop from the pump device 6 immediately after the tank 3 is removed. Further, the pump device 6 is separated from the tank 3 and the check valve 97 in the filter device 8 is connected to the intake port 10.
4 is closed, so that the hands of the user holding the tank 3 do not get wet.

On the other hand, when the tank 3 is mounted, the tank 3 is pushed through the opening 20 on the lower surface of the main body. Thereby, the pump device 6 on the cabinet 21 side is press-fitted into the cylinder port 62, and the pressing boss 66 pushes up the discharge port valve 131 to open. After the tank 3 is completely mounted, the locking portion 82
A, 82B are locked portions 85A, 85B of main body substrate 100.
To lock. This ensures that tank 3 is in cabinet 2
It is held at 1.

In the air purifying apparatus 1 provided with the transport mechanism 7 having the tank attaching / detaching function, when the tank 3 is detached from the cabinet 21, the left and right fixed levers 81A and 81B protruding outside the cabinet 21 are used. However, the cabinet 21 can be lifted by holding the left and right fixing levers 81A and 81B without switching to the handles 80A and 80B for gripping the main body. Thereby, the main body substrate 1 with the cabinet 21 and the tank 3
00 can be easily separated.

When the tank 3 is mounted on the cabinet 21, the left and right fixing levers 81A and 81B enter the storage portions 86A and 86B of the cabinet 21 so that the non-storage surfaces coincide with the peripheral surface of the cabinet 21. Since the left and right fixing levers 81A and 81B are locked to the cabinet 21, the external shape of the air purifying device 1 is visually clear and gives an aesthetic effect to the user.

Subsequently, a maintenance method of the air cleaning device 1 will be described. When the air cleaning device 1 has been used for a long period of time, it is preferable to periodically clean the device because the inside of the device is soiled by the circulation of water containing dust and the like.

In this air purifying apparatus 1, with the main substrate 100 with the tank 3 shown in FIG. 18 removed, as shown in FIG. 19, the spraying device 2, the liquid transfer mechanism 9 and the pump device 6 are integrally removed. Thus, the spraying device 2 can be cleaned.

In FIG. 19, a rotating body insertion guide portion 17 is detachably attached to the lower portion of the second vertical partition plate 31. As shown in FIG. 20, the rotating body insertion guide portion 17 has an inner diameter φ2 substantially equal to the outer diameter of the water spray rotating body 41. The rotating body insertion guide section 17 supports the annular section 37 having a predetermined thickness d2 for guiding the water spray rotating body 41, the three beam sections 47A to 47C supporting the annular section 37, and the beam sections 47A to 47C.

After disassembly, when the liquid transport mechanism 9 is mounted on the main body, and when the upper connecting portion 153 and the lower connecting portion 154 described below are connected, the rotating body insertion guide 17 is 41 will be guided.

That is, the shaft 33 can be separated above the spraying device 2 as shown in FIG. For example, the shaft 33 includes an upper shaft 151 and a lower shaft 152, and a lower portion of the upper shaft 151 is fixedly inserted into an upper connecting portion 153 as shown in FIG. 21, while an upper portion of the lower shaft 152 is fixed to a lower connecting portion 154. (See FIG. 19). Note that the water spray rotating body 41 of the spray device 2 is attached to the lower connecting portion 154.

As shown in FIG. 22, the lower portion of the upper connecting portion 153 is a cylindrical body having an upper triangular pyramid portion 156 (guide portion) formed at a predetermined depth along the axial direction from the lower surface around the upper shaft 151. Insertion hole 161 (FIG. 21B). In the cross section of the insertion hole 161, two opposing surfaces are formed in an arc shape, and the other two surfaces are formed in a planar shape (FIG. 21A).

On the other hand, the lower connecting portion 154 is a column having a lower triangular pyramid portion 157 (guided portion) formed on the upper portion, and its cross section is inserted into the insertion hole 161 (FIG. 21A) of the upper connecting portion 153. It is formed corresponding to this as possible.

As shown in FIG. 3 described above, the connecting projections 162, 16
2 are provided on two opposing surfaces. On the other hand, the lower connecting portion 15
4 are provided with connecting concave portions 163 and 163 on which the connecting convex portions 162 and 162 are hooked.

The upper and lower connecting portions 153 and 154 are connected by engaging these connecting convex portions 162 and 162 with the connecting concave portions 163 and 163. Further, as shown in FIG. 21A, since the lower connecting portion 154 is formed by a combination of an arc surface and a plane, when the upper connecting portion 153 rotates, the lower connecting portion 154 also rotates.

Next, an operation procedure for removing the spraying device 2, the pump device 6, and the liquid transfer mechanism 9 in the air cleaning device 1 will be described. From the state where the tank 3 shown in FIG. 19 is removed, the pump device 6 and the like are pulled downward. As a result, as shown in FIG. 19, the press-fitting portion 155 comes off from the main body, the lower connecting portion 154 comes off from the upper connecting portion 153, and the spraying device 2, the pump device 6, and the liquid transfer mechanism 9 are integrated from the main body. They can be separated and extracted from the lower surface opening 20.

By removing the spray device 2, the pump device 6, and the liquid transport mechanism 9, dirt adhering to the spray device 2 and the water reservoir 28 can be easily cleaned.
Also, when each component such as the pumps 34 and 35 breaks down, it is easy to replace the component.

Further, when the detached spraying device 2, the pump device 6, and the liquid transfer mechanism 9 are mounted on the main body, the water spraying rotator 41 is moved from the lower opening 20 of the main body via the rotator insertion guide portion 17. And press-fitting part 155
Into the main unit.

At this time, as shown in FIG. 21A, the shape of the insertion hole 161 of the upper connecting portion 153 is
4 needs to be inserted in a predetermined direction. Therefore, in the present embodiment, as shown in FIG. 22, the outer peripheral portion of the water spray rotator 41 is restricted in horizontal deflection by the rotator insertion guide portion 17, so that when the rotator insertion guide portion 17 is not provided, In comparison, the lower connecting portion 154 and the upper connecting portion 153 can be positioned quickly.

Here, when the lower connecting portion 154 is connected to the upper connecting portion 153 as shown in FIGS. 21B and 23, the triangular pyramids 156 and 157 first come into contact with each other. At this time, the top of the lower triangular pyramid part 157 of the lower connecting part 154 is guided by the slope of the upper triangular pyramid part 156 of the upper connecting part 153, and as shown in FIG. Are rotated in opposite directions. As a result, the lower connecting portion 154 is inserted into the insertion hole 1 as shown in FIG. 21A.
It is in a predetermined direction with respect to 61.

In this state, the lower connecting portion 154 is inserted into the insertion hole 16.
1, the connecting projections 162, 1 as shown in FIG.
62 is engaged with the connection recesses 163 and 163, and the upper shaft 151
And the lower shaft 152 are connected.

Therefore, the upper connecting portion 153 and the lower connecting portion 1
When connecting 54, it is not necessary to care about the orientation of the lower connecting portion 154, and the mounting can be performed with good reproducibility and in a short time. Thereby, the assembling time of the air cleaning device 1 can be shortened, and the maintenance thereof can be simplified. Further, since the spraying device 2, the pump device 6, and the liquid transfer mechanism 9 can be integrally removed, maintenance such as cleaning or component replacement can be easily performed.

As shown in FIG. 25, when the cylindrical body 15 having a predetermined height h is mounted on the rotating body insertion guide portion 17, horizontal runout in a portion close to the connection portion occurs. Because of the severe limitation, the upper connecting portion 15 is further improved.
3 and the lower connecting portion 154 are easily connected.

Next, a description will be given of a filter attaching / detaching mechanism of the air purifying apparatus 1. FIG. When the air purifying device 1 is used for a long time, the air containing relatively large dust and the like may
Since the air filter 18 provided in the intake port 11 becomes dirty, it is preferable to periodically clean the air filter 18.

When the air inlet cover 11A shown in FIG. 16 is removed in this air purifying apparatus 1, the air inlet 11 communicating with the air intake duct 22 is exposed as shown in FIG. 26A.
By removing the air filter 18 as shown in B, the air filter 18 can be cleaned or replaced.

In FIG. 26A, the cabinet 21 is provided with an intake port (air intake port) 11 having a curved shape. Upper and lower portions of the intake port 11,
A groove 21 is provided inside the cabinet 21 along the curved surface of
A, 21B are provided. These grooves 21A, 21B
In contrast, an air filter 18 as shown in FIG. 26B is detachably provided.

This air filter 18 has a reversible filter frame 18A having a shape larger than the shape of the opening of the intake port 11. The intake port 11 has a width W and a height H.
On the other hand, the air filter 18 has a width of W + α and a height of H + β. α and β are protrusion distances, for example, each width W + α and height H + β of the air filter 18.
May be set to a length that does not exceed the length of the diagonal line of the intake port 11. The air filter 18 can be easily inserted into the cabinet 21 along the diagonal line of the intake port 11.

The air filter 18 is formed by molding two filter frames 18A each having an opening with a metal mold, and sandwiching a filter member for filtering relatively large dust and dirt between the two frame frames 18A. Thus, they are integrally formed.

In the air purifying apparatus 1 having such an air filter 18, the air filter 18 is mounted on the cabinet 21.
First, the entire air filter 18 is inserted into the cabinet 21 from the diagonal position of the intake port 11, and then, as shown in FIG.
Into the groove 21A at the bottom of the intake port 11. Subsequently, the upper part is formed into the groove 21 on the upper part of the intake port 11.
Insert according to B.

The upper and lower portions of the filter frame 18A are
When the filter frame 18A enters the grooves 21A and 21B, both ends of the filter frame 18A are regulated on both sides of the intake port 11 by the restoring force of the filter frame 18A to return to the original shape as shown in FIG. The frame 18A comes to be caught. At this time, the left and right ends β / 2 of the filter frame 18A are caught by the intake port 11, and the upper and lower ends α / 2 thereof are locked by the grooves 21A and 21B.

Accordingly, since the air filter 18 can be locked to the cabinet 21 with good reproducibility, the work of mounting the filter can be simplified.

When cleaning the air filter 18, as shown by the two-dot chain line in FIG.
By pressing the air filter from the outside, the upper and lower portions of the filter frame 18A come off the grooves 21A and 21B, so that the air filter 18 can be easily removed from the cabinet 21. Therefore, replacement work of the air filter 18 of the air cleaning device 1 can be reduced as compared with the conventional system.

Next, the motor driving device 88 of the air cleaning device 1 will be described. In the air purifying apparatus 1, as described above, the shaft 33 is rotated by the single motor 5, so that the fan 4, the water spray rotating body 41, and the pump device 6 are rotated.
Is to be driven.

In this apparatus, it is necessary to smoothly start the water spray rotating body 41 whose posture is stabilized particularly by the gyro effect. Therefore, in this device, a motor driving device 88 is provided,
As time elapses from the start of the motor 5, the motor 5
The attitude of the water spray rotating body 41 is stabilized by raising the rotation speed of the water spray rotating body 41 in one step, multiple steps, or steplessly.

As shown in FIG. 29, the motor driving device 88 is provided with a timer 38. The time is counted from the start of the motor 5 based on a start signal S0, and a time count signal S1 is output. The detection unit 4 is provided at the output stage of the timer 38.
8 is connected, the elapsed time from the start of the motor 5 is detected, and a time detection signal S2 is output. A control unit 58 is connected to an output stage of the detection unit 48, and controls the rotation speed of the motor 5 based on the time detection signal S2. The control unit 58 outputs a start signal S0 to the timer 38 when the motor is started.

A thyristor 68 is connected to the output stage of the control unit 58, and the conduction period of the motor drive current Im is controlled by the gate control voltage VG from the control unit 58. A power supply 78 is connected to the thyristor 68 so that the motor drive voltage V
p is applied. For example, the thyristor 68 controls so that the duty ratio of the energization period of the drive current Im of the motor 5 gradually approaches 100% as the time elapses from the start of the motor 5.

In the air purifying apparatus 1 having such a motor driving device 88, for example, the motor driving current Im is changed in four stages (25%, 50%, 75%, 100%) with the passage of time.
%), First, as shown in FIG. 30A, during the period from the motor start time t0 to the time t1, the pulse width P1
Is applied to the thyristor 68. Thereby, the duty ratio of the motor drive current Im can be set to 25% as shown in FIG.
The target rotation speed of the water spray rotating body 41 can be suppressed to 1/4.

As shown in FIG. 30C, a gate control voltage VG (50%) having a pulse width P2 is applied to the thyristor 68 during a period from time t1 to time t2. As a result, the duty ratio of the motor drive current Im can be set to 50% as shown in FIG.
One target rotation speed can be halved.

Further, as shown in FIG. 30E, a gate control voltage VG (75%) having a pulse width P3 is applied to the thyristor 68 during a period from time t2 to time t3. Thereby, the duty ratio of the motor drive current Im can be set to 75% as shown in FIG.
Can be reduced to 3/4.

After time t3, gate control voltage VG (100%) is changed to thyristor 68 as shown in FIG.
Is applied to Thereby, the motor drive current Im as shown in FIG. 30H can be supplied to the motor 5, and the water spray rotating body 41 can be set to the target rotation speed.

As the time elapses as described above, the rotation speed of the motor 5 is increased in four steps by the control unit 58. As the rotation speed increases, the attitude of the water spray rotating body 41 is stabilized by the gyro effect. Become like

Therefore, it is possible to prevent vibration and abnormal noise due to the eccentricity of the water spray rotator 41 generated by rotating the water spray rotator 41 at the target rotation speed from the beginning. As a result, the air cleaning device 1 can be started smoothly, and the life of the device can be extended.

The driving voltage Vp of the motor 5 may be controlled by the control unit 58 in four steps as shown in FIG. In this case, a drive voltage Vp of 25% is applied to the motor during a period from the motor start time t0 to the time t1. Thereby, the target rotation speed of the water spray rotating body 41 can be suppressed to approximately 1/4.

In the period from time t1 to time t2, 50% drive voltage Vp is applied to motor 5. Thereby, the target rotation speed of the water spray rotator 41 can be reduced to approximately half. Further, during a period from time t2 to time t3, a drive voltage Vp of 75% is applied to the motor 5. As a result, the target rotation speed of the water spray rotating body 41 becomes 3
/ 4.

After time t3, 100% drive voltage Vp is applied to motor 5. Even in this case, the attitude of the water spray rotating body 41 can be stabilized with the passage of time.

Further, as shown in FIG. 32, the drive voltage Vp of the motor 5 may be controlled by the controller 58 in a stepless manner. In this case, assuming that the slope of the voltage control characteristic is θ, during the period from the motor start time t0 to the time t1, (t1
−t0) The drive voltage Vp of tan θ is applied to the motor. Thereby, the target rotation speed of the water spray rotating body 41 can be gradually approached. Even in this case, the attitude of the water spray rotating body 41 can be stabilized with the passage of time.

Next, the water level detecting device 10 of the air cleaning device 1 according to the present invention will be described. This air purifier 1
Is controlled so that the rotation of the motor 5 is automatically stopped when the amount of water stored in the tank 3 decreases below a prescribed amount or when the tank 3 is removed from the main body during operation of the apparatus. .

The determination of the fluctuation and presence / absence of the water level in the tank 3 is performed by the water level detecting device 10 shown in FIG.
The water level detection device 10 detects a fluctuation in the water level of the tank 3 and the presence or absence of the tank 3 without electrically connecting the tank 3 and the main body with a signal line or the like.

The water level detecting device 10 comprises a floating portion 171 mounted inside the tank 3 and a detecting portion 172 for detecting a fluctuation of the floating portion 171. This floating part 17
1 is a rod-shaped body 17 which is attached to the tank so as to be movable up and down.
3 and the float 1 attached to the lower end of the rod 173
Consists of 74.

A cylindrical bottom cylindrical portion 175 is formed on the inner bottom surface of the tank 3, and a cylindrical projecting cylindrical portion (projecting portion) 176 is provided on the upper surface of the tank 3. Rod 1
The lower end of 73 is formed in a cylindrical shape, and the inside thereof is an insertion hole 177.
Here, the bottom cylindrical portion 175 is inserted. The upper end of the rod-shaped body 173 is inserted into the protruding cylindrical portion 176 of the tank 3.

A light-transmitting hole (light-transmitting portion) is provided above the rod 173.
178 is provided, and is used for light detection of the detection unit 172 described later. The rod 173 is formed of, for example, a black material so as not to transmit light except for the light transmitting hole 178. Further, the water level detecting device 10 is optically
The tank 3 is formed of a transparent material because the position of the tank 3 is to be detected and light needs to be transmitted.

When the rod 173 is at the uppermost position, the bottom cylindrical portion 175 is prevented from falling out of the insertion hole 177, and when the rod 173 is at the lowermost position, the projecting cylindrical portion 1 is formed.
The rod 76 does not fall out of the rod 173. That is, the rod-shaped body 173 is held by the bottom cylindrical portion 175 and the protruding cylindrical portion 176, and is attached so as to be vertically movable within a predetermined range.

The rod 173 moves according to the water level inside the tank 3 by the buoyancy of the float 174. For example, when the water level in the tank 3 exceeds a specified water level (hereinafter also referred to as a threshold water level) Lth, the rod 173 moves to the uppermost position by buoyancy given by the float 174. At this time, the upper end of the rod-shaped body 173 has the projecting cylindrical portion 1.
The position is regulated by abutting on the upper part of the inner surface of 76. on the other hand,
When the water level in the tank 3 falls below the threshold water level Lth, the rod 173 moves downward by the float 174 corresponding to the water level.

The detector 172 shown in FIG. 34 and FIG.
It is composed of a photo interrupter 181 which is a transmission type sensor, a light blocking lever 182 for preventing malfunction, and a support portion 183 for supporting the light blocking lever 182.

As shown in FIG. 34, a horizontal partition plate 184 is provided inside the cabinet 21 and above the tank 3.
Are provided, and columnar mounting bosses 185 and 185 project from the upper surface of the partition plate portion 184. The photo interrupter 181 has a light emitting portion 187 and a light receiving portion 188 (FIG. 35) on the lower side, and a screw 1 is provided above the mounting bosses 185 and 185.
91,191. The round hole 19 through which the protruding cylindrical portion 176 (FIG. 33) is inserted corresponding to between the light emitting portion 187 and the light receiving portion 188 of the photo interrupter 181.
9 are provided.

As shown in FIG. 35, the U-shaped portion of the photo interrupter 181 has one
Is attached, and the light receiving section 188 is attached to the other. Here, a change in the water level of the tank 3 is detected based on whether or not the light from the light emitting unit 187 has reached the light receiving unit 188.

As shown in FIG. 36, a comparator 124 is connected to the output stage of the light receiving section 188, and the light detection signal S3 output from the light receiving section 188 is compared with a reference signal VREF relating to a preset threshold water level Lth. You. If the photodetection signal S3 is weak, a current / voltage conversion circuit may be provided to make the photodetection signal S3 a photodetection voltage and then compare it with the reference signal VREF (see FIG. 36). The threshold water level Lth is set to be higher than the water level of the tank 3 which causes an irregular operation caused by circulating the reduced water between the tank 3 and the spray device 2.

Here, the irregular operation means the following state. For example, assuming that the threshold water level Lth of the tank 3 for stopping the motor 5 is the position of the water intake 104 of the filter device 8 below the pump device 6, this water intake 104
If there is sufficient water as described above, the motor 5 will not be stopped, and the pump device 6 will continue to be driven, and water will be pumped from the water intake 104.

However, in a state where the water level has decreased to the threshold water level Lth, when the water level in the tank 3 drops due to the pumping of the water, and the water level falls below the intake port 104, the motor 5 is stopped. Accordingly, the pump device 6 is stopped.

Further, as described above, in the present embodiment, most of the water sprayed by the water spray rotating body 41 and sprayed by the spraying device 2 passes through the water reservoir 28, the drain outlet 122, and the circulation drainage channel 121, and the main body drainage. It is configured to be collected in the tank 3 through the port 123. Thereby, the water level of the tank 3 rises again higher than the water intake 104, and it is detected by the water level detection device 10 that the water level has returned to the predetermined water level.
The motor 5 is driven again by this detection.

By repeatedly lowering and raising the water level, the driving and stopping of the motor 5, the fan 4 driven by the motor 5, the water spray rotating body 41, and the pump device 6 are repeated. This is an irregular operation state, and unless the threshold water level Lth is set to an appropriate position, the life of the apparatus itself is significantly reduced. Therefore, in the present embodiment, the threshold water level Lth is set at a position higher than the water level at which such irregular operation occurs, for example, the threshold water level Lth is set at the position of the pump 34 higher than the water intake 104. .

Returning to FIG. 36, when the light detection signal S3 is equal to or lower than the reference signal VREF, the comparator 124 outputs a low signal.
Level (hereinafter referred to as “L” level) water level detection information D1
Is output, and when the light detection signal S3 exceeds the reference signal VREF, the water level detection information D1 at a high level (hereinafter, referred to as "H" level) is output. A microcomputer 125 is connected to the output stage of the comparator 124, and the water level detection information D1 from the comparator 124 is determined.

For example, when the water level in the tank 3 reaches the threshold water level Lth, the power supply 78 is controlled by the microcomputer 125, so that the power supply to the motor 5 is turned off. Thus, the operations of the fan 4, the spray device 2, and the pump device 6 are stopped. Note that an alarm circuit 126 is connected to the microcomputer 125 so that the operation stop of the spray device 2 and the like is notified.

Returning to FIG. 34, the support portion 183 is substantially L
And the horizontal plate portion 192 is attached to the mounting boss 1.
85 and 185 and the photointerrupter 181 are fixed by screws 191 and 191. On the upper part of the vertical plate portion 193, a lever mounting plate portion 194 having a substantially U shape in a top view is formed.

A lever shaft 195 is inserted between the opposite plate portions of the lever mounting plate portion 194.
In addition, a light-blocking lever 182 used for determining the presence or absence of the tank 3 is attached rotatably downward. This shading lever 1
82 is a light shielding portion 1 having a wide width by refracting the lower end of the prism member.
96 are provided.

When the tank 3 is mounted as shown in FIG. 33, the projecting cylindrical portion 176 of the tank 3 is inserted into the round hole 199 and contacts the light-shielding lever 182 to rotate it counterclockwise. On the other hand, when the tank 3 is removed,
Are the light emitting unit 187 and the light receiving unit 1 of the photo interrupter 181.
88 (FIG. 35) to block the optical path.

The water level detecting device 10 configured as described above
The operation will be described below. First, detection of a change in the water level of the tank 3 will be described.

As shown in FIG. 33, the tank 3 is full.
Is attached, the rod 173 is pushed up to the uppermost position by the buoyancy of the float 174. At this time, as shown in FIG. 35, the light transmitting hole 178 coincides with the optical path of the light emitting unit 187 of the photo interrupter 181, and the light from the light emitting unit 187 passes through the light transmitting hole 178 and the light receiving unit 18
Reach 8.

The output of the light receiving section 188 is monitored by the microcomputer 125 according to the control flowchart shown in FIG. That is, the microcomputer 125 that has input the water level detection information D1 from the comparator 124 in step A1 determines whether the water level in the tank 3 exceeds the threshold water level Lth in step A2.
If the water level detection information D1 at the “L” level is detected by the comparator 124, it is determined that the water level in the tank 3 has exceeded the threshold water level Lth. Because it is stored in 3,
Returning to step A1, monitoring of the water level is continued.

Then, as shown in FIG. 38, when the water level in the tank 3 falls below the threshold water level Lth, the rod 173 moves downward. As a result, the light transmitting hole 178 is displaced from the optical path, the rod 173 blocks light from the light emitting section 187, and the light receiving body 188 (FIG. 36) does not detect light.

As a result, the comparator 124 detects that the water level has dropped, and outputs "H" level water level detection information D1. In the microcomputer 125 to which the “H” level water level detection information D1 has been input in step A3, the power supply control signal S4 is output to the power supply 78.

When the power of the motor 5 is turned off, for example, by the power control signal S4, the operations of the fan 4, the spray device 2, and the pump device 6 are stopped. With this,
An alarm signal S5 is output from the microcomputer 125 to the alarm circuit 126. This alarm signal S5
This informs the user that the operation of the spray device 2 and the like has stopped.
Thereby, the user can be promptly prompted to supply the water for cleaning the air stored in the tank 3.

In the air purifying apparatus 1 provided with the water level detecting device 10 as described above, when the water level in the tank 3 reaches a preset threshold water level Lth, the microcomputer 12
Since the operation of the motor 5 is stopped by 5, vibration generated by circulating the reduced water between the tank 3, the pump device 6 and the spray device 2 can be prevented. This stabilizes the operation of the air cleaning device 1 and extends the life thereof.

Next, detection of the presence or absence of the tank 3 will be described. When the tank 3 is mounted as shown in FIG. 33, the light blocking lever 182 is in contact with the protruding cylindrical portion 176 of the tank 3 and rotates counterclockwise.

When the tank 3 is removed during the operation of the air purifying apparatus 1, the regulation of the protruding cylindrical portion 176 is eliminated, so that the light-blocking lever 182 is rotated clockwise and substantially as shown by a two-dot chain line. It is arranged vertically. At this time, the light shielding portion 196
Is disposed at a position where the light transmitting hole 178 of the rod-shaped body 173 was located,
The light from the light emitting unit 187 (FIG. 35) of the photo interrupter 181 is blocked. This detects that the tank 3 has been removed, and stops driving the motor 5 (FIG. 36).

As described above, when the tank 3 is removed from the main body during the operation of the air purifying apparatus 1, the operation is stopped by detecting this, and the operation is continued without supplying water to the main body. Is avoided.

In this water level detecting device 10, the water level of the tank 3 and the presence or absence of the water level can be detected without electrically connecting the tank 3 and the main body with a signal line or the like. Therefore, tank 3
There is no need for electrical connection between the main body and the main body, and the configuration of the entire apparatus can be simplified.

In this embodiment, the light-shielding lever 182 is arranged at the light-shielding position by its own weight. However, the light-shielding lever 182 may be urged to be always arranged at the light-shielding position by an urging means such as a spring. According to this, even if the entire device falls,
Operation is stopped without malfunction.

In this example, the case where the power supply control regarding the presence or absence of the tank 3 is performed by the light blocking lever 182 and the microcomputer 125 has been described.
A single switch such as a micro switch may be provided between the tank 1 and the tank 3, and when the tank 3 is detached from the cabinet 21, the power of the motor 5 may be turned off by this switch. Thereby, the load on the control unit can be reduced and the cost can be reduced.

Next, the abnormality detecting device 19 of the air cleaning device 1 according to the present invention will be described. This air purifier 1
When the rotation speed of the fan 4, the spray device 2, the pump device 6, etc., decreases below a preset lower threshold speed,
Alternatively, when the speed exceeds the upper threshold speed, control is performed so that the rotation of the motor 5 is automatically stopped. In this example, the motor 5 rotates at two different speeds, a high mode (3000 rpm) and a low mode (1000 rpm).

The fluctuation of the rotation speed of the motor 5 is detected by a speed sensor 29 shown in FIG. One of the three sensors is used as the speed sensor 29. As shown in FIG. 40A, the speed sensor 29A has a disc-shaped body 107 attached to the rotating shaft 5A of the motor 5, and one light transmitting portion 108 opened at the outer peripheral end of the disc-shaped body 107.
And a photo interrupter 109 arranged in a non-contact manner so as to straddle the disc-shaped body 107. Although not shown, the photo interrupter 109 has a light emitting element that irradiates the outer periphery of the disc-shaped body 107 with light and a light receiving element that detects light that has passed through the light transmitting unit 108. The speed sensor 29A outputs a speed detection signal S6 by detecting the light that has passed through the light transmitting portion 108 each time the disc-shaped body 107 makes one turn.

The speed sensor 29B is, as shown in FIG. 40B, a disk 127 mounted on the rotating shaft 5A of the motor 5.
And one magnetic element 128 arranged at the outer peripheral end of the disk-shaped body 127, and a Hall element 129 fixedly arranged at the non-rotating part so as to detect the magnetism of the magnetic element 128. A balancer (non-magnetic material) 130 for the magnetic element 128 is provided on the disk 127 at a position facing the magnetic element 128 in order to facilitate rotation. The speed sensor 29B outputs a speed detection signal S6 by detecting magnetism by the Hall element 129 every time the disk-shaped body 127 makes one turn.

As shown in FIG. 40C, the speed sensor 29C is a disc-shaped body 147 attached to the rotating shaft 5A of the motor 5.
A reflector 148 disposed at an outer peripheral end of the disc-shaped body 147; a light-emitting unit 149 fixed to a non-rotation unit so as to emit light to the reflector 148; And a light receiving element 150 that receives the reflected light from the light source. The speed sensor 29C outputs the speed detection signal S6 by receiving the reflected light from the reflecting portion 148 each time the disc-shaped body 147 makes one turn.

As shown in FIG. 39, a current / voltage conversion circuit (hereinafter referred to as an I / V conversion circuit) 119 is connected to the output stage of the speed sensor 29, and the speed detection signal S6 is converted into a voltage. . An output stage of the I / V conversion circuit 119 is connected to a comparator 49 for a lower limit and a comparator 59 for an upper limit. In the comparator 49 for the lower limit,
Speed detection voltage Vs output from I / V conversion circuit 119
Are two speed modes set in advance (1000/3
000 rpm) (800/28)
00 rpm) is compared with the reference signal V1 or V3. The reference signal V1 sets the lower threshold speed of the motor 5 in the low mode at 800 rpm, and the reference signal V3 sets the lower threshold speed of the motor 5 in the high mode at 2800 rpm.

In the upper limit comparator 59, the speed detection voltage Vs output from the I / V conversion circuit 119 is set to a predetermined upper limit threshold speed (1200/3200 rpm).
With reference signal V2 or V4. This reference signal V2 is the upper threshold speed 1 when the motor 5 is in the low mode.
200 rpm is set, and the reference signal V4 sets the upper threshold speed 3200 rpm of the motor 5 in the high mode.

In the low mode of the motor 5, when the speed detection voltage Vs is lower than the reference signal V1, the "H" (high) level speed detection information D21 is output from the comparator 49, and the speed detection voltage Vs is used as the reference signal. If it exceeds V1, "L" (low) level speed detection information D21 is output. When the speed detection voltage Vs is equal to or lower than the reference signal V2, "H" level speed detection information D22 is output from the comparator 59, and the speed detection voltage Vs is set to the reference signal V2.
Is exceeded, "L" level speed detection information D22 is output.

In the high mode of the motor 5, if the speed detection voltage Vs is equal to or lower than the reference signal V3, the "H" level speed detection information D31 is output from the comparator 49,
When the speed detection voltage Vs exceeds the reference signal V3, "L" level speed detection information D31 is output. Also,
"H" when the speed detection voltage Vs is equal to or lower than the reference signal V4.
When the speed detection voltage Vs exceeds the reference signal V4, the "L" level speed detection information D32 is output.

A microcomputer 89 is connected to the output stages of the comparators 49 and 59.
And speed detection information D21, D22, D31, and D32 from steps 59 and 59 are determined. In the low mode, the speed detection information D21, D22
Are set to the “H” level, it is determined that the rotation speed of the motor 5 is 800 rpm or less (abnormal). If both of the speed detection information D21 and D22 are at the "L" level, it is determined that the rotational speed of the motor 5 has exceeded 1200 rpm (abnormal). When the speed detection information D21 is at "L" level and D22 is at "H" level,
The rotation speed of the motor 5 exceeds 800 rpm and 1200 rpm
The state is determined to be m or less (normal).

In the high mode, the speed detection information D3
If both 1 and D32 are at the "H" level, it is determined that the rotation speed of the motor 5 is 2800 rpm or less (abnormal). Both of the speed detection information D31 and D32 are "L"
If the rotation speed reaches the level, the rotation speed of the motor 5 becomes 3200
It is determined that the state exceeds rpm (abnormal). When the speed detection information D31 is at "L" level and D32 is at "H" level, the rotation speed of the motor 5 exceeds 2800 rpm and 3
It is determined that the state is 200 rpm or less (normal).

The above-mentioned reference signals V1 to V4 are set via the microcomputer 89. A power supply 78 is connected to the microcomputer 89, and the second speed of the motor 5 is controlled based on the Low / High mode signal S7 from the microcomputer 89. Note that an alarm circuit 99 is connected to the microcomputer 89 to notify the operation of the spray device 2 and the like to stop.

As shown in FIG. 41, when the rotation speed of the motor 5 is set to the high mode in step B1, as shown in FIG.
Moving to step B2, the microcomputer 59 rotates the motor 5 via the power supply 78 so as to be 3000 rpm.

If there is no instruction to stop the motor 5 in step B3, the flow shifts to step B4 to detect whether or not the rotation speed of the motor 5 has fallen below the lower threshold speed (2800 rpm). If the rotation speed is not lower than the lower threshold speed, the process proceeds to step B5 and the motor 5
Is detected whether the rotation speed exceeds the upper threshold speed (3200 rpm).

If the rotation speed does not exceed the upper limit threshold speed, the flow returns to step B3 to continue monitoring the rotation speed. In this state, the comparator 49 outputs the "L" level speed detection information D31, and the comparator 59 outputs the "H" level speed detection information D32.

In step B2, when the rotation speed of the pump device 6 is lower than the lower threshold speed (2800 rpm), for example, a liquid such as water freezes in a cold region or the like, and the pumping load becomes heavy, or foreign matter is caught. When the pumping load becomes heavy, the comparators 49 and 59 both output "H" level speed detection information D31 and D32, so that step B
6 and the microcomputer 89 supplies the power 7
8 is controlled, and the power of the motor 5 is turned off, so that the operations of the fan 4, the spray device 2, and the pump device 6 are stopped. As a result, damage to the pump device 6 and the motor 5
Can be prevented from burning.

In addition, the water intake 1 of the filter device 8 described above.
When the water is frozen near 04 and the pumping load becomes extremely light, etc., the rotation speed of the motor 5 may exceed 3200 rpm. Therefore, in step B5, both the comparators 49 and 59 detect the "L" level speed. Information D31, D32
Is output, this state can be detected. Thereby, the operation of the pump device 6 and the like can be stopped by turning off the power of the motor 5 in step B6.

If the low mode is set in step B1, the process proceeds to step B7, where the microcomputer 59 rotates the motor 5 via the power supply 78 so as to be at 1000 rpm. If there is no stop instruction of the motor 5 in step B8, the process proceeds to step B9 to detect whether the rotation speed of the motor 5 has become equal to or lower than the lower limit threshold speed (800 rpm). If the rotation speed is not lower than the lower threshold speed, the process proceeds to step B10, and the rotation speed of the motor 5 is set to the upper threshold speed (1200 rpm).
m) is detected. If the rotation speed does not exceed the upper threshold speed, the process returns to step B8 to continue monitoring the rotation speed. In this state, the comparator 49 outputs the "L" level speed detection information D21, and the comparator 59 outputs the "H" level speed detection information D22.

If the rotation speed of the motor 5 is lower than the lower limit threshold speed (800 rpm) in step B8, the comparators 49 and 59 both output "H" level speed detection information D21 and D22. Then, the power supply 78 is controlled by the microcomputer 89 and the power supply of the motor 5 is turned off, so that the operations of the fan 4, the spray device 2, and the pump device 6 are stopped. Thus, damage to the pump device 6 and burning of the motor 5 can be prevented.

When the rotation speed of the motor 5 is 1200 rpm
If it exceeds m, the comparators 49 and 59 both output "L" level speed detection information D21 and D22, so the flow goes to step B6 to turn off the power of the motor 5 and thereby the pump device 6 and the like. Operation can be stopped.

As described above, the air purifying apparatus 1 of the present embodiment
In this case, the motor 5, the fan 4, the spray device 2, and the pump device 6 can be protected from a severe use environment and the service life thereof can be extended.

In the present embodiment, the case of the pump device 6 having the two pumps 34 and 35 as shown in FIG. 11 has been described. However, the present invention is not limited to this.
The pump device 600 provided with only a single pump 34A as shown in FIG.

In this embodiment, the control unit 58 as shown in FIG. 29, the microcomputer 125 as shown in FIG. 36, and the microcomputer 89 as shown in FIG. A case has been described in which power supply control for water level detection and power supply control for abnormality detection are performed. Of course, these controls may be performed by a single microcomputer.

Further, the spraying device 2 shown in FIGS.

Although the configuration and the like according to 2) have been described as examples applied to the air cleaning device 1, these inventions are extremely suitable for application to other devices using a liquid such as a humidifier, a cooler, and an oil stove. is there.

(2) Second Embodiment FIG. 43 shows the configuration of a negative ion generator 201 according to a second embodiment of the present invention. The negative ion generator 201 of the present embodiment focuses on atomized water (fine water droplets) generated by the centrifugal force of the spraying device 2 which is a rotating body, and the structure itself is the same as that of the air cleaning device 1 described above. is there.

The operation of the negative ion generator 201 will be described with reference to FIG. When the power of the negative ion generator 201 is turned on, the water jetted from the water supply pipe 43 flows out of the spraying device 2 rotating at high speed into the intake duct 22 as fine mist water, which serves as a steam-water mixing unit. The air sucked from the inlet 11 passes through the mist water and is discharged from the outlet 12.

As is well known, for example, the mist purified water spouting around a waterhole contains many negative ions due to the so-called "Lenard effect". Therefore, also in the case of the negative ion generator 201 of the present invention, a large amount of negative ions are contained in the clean air exhausted into the room due to the “Lenard effect”, and the negative ions reduce the calming effect and the recovery from fatigue. Many effects on the human body such as promotion can be expected.

Other effects of negative ions include enhancing cardiopulmonary function to regulate blood pressure and respiration, lowering blood sugar levels, and healing effects on burns. A comfortable indoor environment can be realized. The effect of promoting the growth of living things (plants) can also be improved.

The negative ions are, for example, high voltage (about 30
(00 V or more). However, in this case, there is a problem in environmental protection because power consumption is large and harmful substances such as ozone are generated at the same time. In this example, since the water is used as described above and this water is atomized by the spraying device 2 to generate negative ions, high power is not required and ozone is not required. No harmful substances are generated.

[0220] The smaller the number of negative ions ejected, the more negative ions can be generated. Therefore, the fin-shaped projecting wall 14 described in FIG.
It is possible to generate more negative ions simply by rotating the spraying device 2 using the porous cylindrical body 15 described in FIGS. 6 and 7 at a high speed, so that the negative ion effect can be relatively easily enhanced. Can be.

(3) Third Embodiment FIG. 44 shows a humidifier 30 according to a third embodiment of the present invention.
1 is shown. The humidifier 301 of the present embodiment focuses on atomized water (fine water droplets) generated by the centrifugal force of the spraying device 2 as a rotating body, and the structure itself is the same as that of the air cleaning device 1 described above.

FIG. 44 shows the operation of the humidifier 301.
This will be described with reference to FIG. When the power of the humidifier 301 is turned on, the water jetted from the water supply pipe 43 flows out of the spray device 2 rotating at a high speed into the intake duct 22 as fine mist water, which serves as a steam-water mixing unit. The air sucked from the inlet 11 passes through the mist water and is discharged from the outlet 12.

In the humidifier 301, the finer the water droplets to be ejected, the more mist water to be mixed with the air. Therefore,
It is possible to generate more humid air only by rotating the spray device 2 using the fin-shaped projecting wall 14 described in FIG. 4 or the perforated cylindrical body 15 described in FIGS. Therefore, the humidification efficiency can be relatively easily increased.

As described above, in the liquid micronizing apparatus according to the present invention, since the second cylindrical body having a plurality of apertures is provided inside the first cylindrical body, the liquid spray rotation is performed. The liquid ejected from the tangential direction of the body is micronized by passing through the opening of the second cylindrical body, and the micronized liquid collides with the inner wall of the first cylindrical body. As a result, fine liquid particles are generated. Therefore, the liquid can be further atomized, and the Leonard effect can be promoted.

In the air purifying apparatus of the present invention, since the cylindrical body having a plurality of openings is provided inside the liquid micronizing unit, the liquid ejected from the tangential direction of the liquid spray rotating body is The liquid is refined by passing through the opening of the cylindrical body, and the finely divided liquid collides with the inner wall of the liquid refined portion, thereby generating mist-like fine liquid particles.

Therefore, when dirty air is passed through the liquid miniaturization section, the chance of even fine dust coming into contact with the liquid filter increases, so that both large and fine dust can be removed, and the air purifying device can be cleaned. Conversion efficiency can be improved.

In the negative ion generator of the present invention, finer liquid particles in the form of mist are similarly generated in the liquid miniaturization section. Therefore, when air is passed through the liquid micronization section, the negative ions mixed with air are removed. The contained gas increases. Therefore,
The air of more negative ions can be generated, and the negative ion generation efficiency of the negative ion generator can be improved.

Similarly, in the humidifier of the present invention, finer liquid particles in the form of mist are generated in the liquid finer portion. Therefore, when air is passed through the liquid finer portion, the fine liquid particles mixed with the air become smaller. Increase. Therefore, since more humid air can be generated, the humidifying efficiency of the humidifier can be improved.

The liquid micronizing device, air cleaning device,
In the negative ion generator and the humidifier, when air is circulated through the liquid fining unit by the air circulating device, the state of the air can be changed by the finer mist liquid, and the liquid fining unit can be changed. Liquid returned from the liquid storage device can be recovered.

Thus, it is possible to provide a liquid refiner, an air cleaner, a negative ion generator, and a humidifier that efficiently utilize the liquid in the liquid storage device.
