Description

  The present invention relates to an air cleaning device including an eliminator device and a fan device.

  Conventionally, as this type of air cleaning device, for example, as shown in FIG. 14, there is a fluff removing device for removing fiber waste floating in the air. An air inlet 102 and an air outlet 103 are provided in the case 101 of the fluff removing apparatus. Further, inside the housing 101, a nozzle pipe 104 for spraying water, an eliminator device 105, and a fan device 106 are provided.

  The eliminator device 105 includes a plurality of fins 107 bent in a U shape and a flow passage 108 formed between the fins 107. These flow passages 108 are bent in a dogleg shape.

  According to this, when the fan device 106 is driven to rotate, the inside of the housing 101 becomes negative pressure, and external air is sucked into the spray chamber 109 in the housing 101 from the air suction port 102, and water is supplied to the nozzle pipe 104. To the air in the spray chamber 109. Thereafter, when the air passes through the flow passage 108 of the eliminator device 105, fine particles such as water droplets contained in the air are separated and removed, and the air passes from the suction side 110 of the fan device 106 to the discharge side 111. It blows out from the blower outlet 103 to the outside.

  In addition, the above-described fluff removing device is described in, for example, Patent Document 1 below.

4-37525

  However, in the above conventional type, the air blowing direction 112 that blows downstream through the flow passage 108 of the eliminator device 105 is set in a direction approaching the suction side 110 of the fan device 106, and thus blows out from the flow passage 108. The air at that time flows smoothly to the suction side 110 of the fan device 106 with almost no change in direction. This increases the possibility that fine particles such as water droplets will pass through the flow passage 108 together with air, and there is a problem that improvement in the capture performance of the eliminator device 105 that captures the fine particles cannot be expected.

  An object of this invention is to provide the air purifying apparatus which can improve the capture | acquisition performance of the eliminator apparatus which capture | acquires microparticles | fine-particles.

In order to achieve the above object, the air cleaning device according to the first aspect of the present invention is provided with an air inlet and an air inlet in a housing,
Inside the housing, an air passage that communicates from the air inlet to the air inlet, an eliminator device that separates and removes particulates contained in the air flowing through the air passage, and a fan device are provided,
The eliminator device has a plurality of bent flow passages,
The fan device is provided on the downstream side of the flow passage of the eliminator device and on the upstream side of the air supply port, and the air that flows into the housing from the intake port and passes through the flow passage of the eliminator device is supplied from the air supply port to the housing. Force it to the outside,
The blowing direction of the air that passes through the flow path of the eliminator device and blows out downstream is set in a direction away from the position of the suction port of the fan device.

  According to this, when the fan device is driven to rotate, external air is sucked into the housing from the air inlet and sprayed with the bactericide solution or the like in the housing and then passes through the flow path of the eliminator device. At this time, since fine particles such as water droplets contained in the air try to go straight by inertia force, they cannot bend through the flow passage and are caught by inertia collision with the wall surface of the flow passage. In this way, the air that has passed through the flow path of the eliminator device is sucked in from the suction port of the fan device and blown out from the air supply port.

  Here, since the blowing direction of the air that passes through the flow path of the eliminator device and blows downstream is set to the direction away from the position of the suction port of the fan device, the air that flows through the flow path of the eliminator device flows When the air is blown downstream from the path, the flow direction is greatly changed toward the suction port of the fan device. In this way, when the air blows downstream from the flow passage, the flow direction of the air is greatly changed, so that the fine particles contained in the air immediately before being blown downstream from the flow passage collide with the wall surface of the flow passage. The possibility of being captured. This improves the capture performance of the eliminator device that captures the fine particles.

In the air purifying device according to the second aspect of the invention, the eliminator device is provided below the air supply port,
The fan device is provided between the eliminator device and the air supply port.
In the third aspect of the invention, the air purifier has a plurality of bent plates arranged at a predetermined pitch in the eliminator device,
A flow path is formed between the bent plates,
The fan device is located near one end of the eliminator device in the direction of the pitch of the bent plate,
The blowing direction of the air that passes through the flow path of the eliminator device and blows downstream is directed to the other end side of the eliminator device.

  According to this, when the air is blown downstream from the flow path of the eliminator device, the flow direction of the air is greatly changed (converted), so that the fine particles contained in the air just before being blown downstream from the flow path There is an increased possibility of being caught by colliding with the bending plate.

  The air purifying device according to the fourth aspect of the present invention is such that the air blowing direction that passes through the flow path of the eliminator device and blows downstream is perpendicular to the rotational axis of the impeller of the fan device. It is set in a direction away from the position.

In the fifth aspect of the present invention, the air purifier includes an eliminator device having a low flow rate eliminator and a high flow rate eliminator,
The low flow eliminator includes a mesh-like or cloth-like capturing member having a large number of minute openings through which air passes,
The flow passage is provided in the high flow rate eliminator and captures fine particles contained in the air by inertial collision.

  According to this, when the air passes through the low flow rate eliminator and the high flow rate eliminator, the fine particles contained in the air are separated and removed. At this time, when the low flow rate air passes through the minute opening of the capture member of the low flow rate eliminator, the particulates in the air collide with the capture member and are captured.

  Also, when high-velocity air passes through the flow path of the high-velocity eliminator, the fine particles in the air try to move straight by inertia force, so the flow path cannot be bent completely and inertially collides with the wall surface of the flow path. Be captured.

  In this way, fine particles in the low flow velocity air are separated and removed mainly by the low flow velocity eliminator, and fine particles in the high flow velocity air are separated and removed mainly by the high flow velocity eliminator. It can handle a wide range of airflows up to airflow.

  The air purifying device according to the sixth aspect of the invention is provided with the eliminator device tilted so that the end portion closer to the fan device of the eliminator device is higher and the end portion far from the fan device of the eliminator device is lower. It is what.

  According to this, by tilting the eliminator device, the air that has flowed through the flow path of the eliminator device is greatly reversed toward the suction port of the fan device when blown downstream from the flow passage. Change direction significantly. This further improves the capture performance of the eliminator device that captures fine particles.

  As described above, according to the present invention, when the air is blown downstream from the flow path of the eliminator device, the air flow direction changes greatly, so that it is included in the air immediately before being blown downstream from the flow path. The possibility that the fine particles collide with the wall surface of the flow path and be captured is increased. This improves the capture performance of the eliminator device that captures the fine particles.

A circulation system 23 is disposed between the circulation tank 22 and the spraying device 14, and the circulation system 23 has a circulation pump 24 to supply the sterilizing agent solution 18 in the circulation tank 22 to the spraying device 14. is there.

  As shown in FIGS. 5 and 6, the eliminator device 15 includes an eliminator case 30, and a low flow eliminator 31 and a high flow eliminator 32 provided in the eliminator case 30.

  The eliminator case 30 is a rectangular box-like case, and has an inflow opening 35 through which the sterilization target air 8 flows on the lower surface and an outflow opening 36 through which the sterilization target air 8 flows out on the upper surface. ing.

  The low flow velocity eliminator 31 and the high flow velocity eliminator 32 are stacked in two stages in the vertical direction (an example of the gas flow direction) in the eliminator case 30. The low flow velocity eliminator 31 is provided in the lower stage, and the high flow velocity eliminator 32 is stacked downstream of the low flow velocity eliminator 31, that is, in the upper stage.

  As shown in FIGS. 6 to 8, the low flow velocity eliminator 31 includes a square frame 39 and a capture member 40 provided in the frame 39. The capture member 40 is a stainless steel wire mesh (mesh) having a large number of minute openings (mesh openings) through which the sterilization target air 8 passes. A plurality of peak portions 43 and valley portions 44 are alternately formed on the capturing member 40.

  As shown in FIGS. 2, 6, 7 and 9, the high flow rate eliminator 32 has a plurality of bent plates 48 arranged at a predetermined pitch P. These bent plates 48 are bent in a substantially U-shape, and a bent flow passage 49 that traps fine particles such as water droplets contained in the sterilization target air 8 by inertial collision is provided between the bent plates 48. Is formed.

  The bent plate 48 has an uneven portion for connection (not shown), and the convex portion of the bent plate 48 is fitted into the concave portion of the adjacent bent plate 48 so that the flow passage 49 is secured. The bent plates 48 are connected to each other.

The high flow rate eliminator 32 is mounted on and supported by a frame frame 39 of the low flow rate eliminator 31.
As shown in FIGS. 3 and 7, the eliminator device 15 is inclined so that the front portion is positioned higher (higher) than the rear portion. Accordingly, the low flow velocity eliminator 31 is inclined such that the front end portions in the longitudinal direction A of the peak portions 43 and the valley portions 44 are higher than the rear end portions, and the high flow velocity eliminator 32 is The front end portion in the longitudinal direction A is inclined so as to be higher than the rear end portion. The longitudinal direction A is orthogonal to the direction B of the pitch P of the bent plate 48.

  As shown in FIGS. 1 to 3, the fan device 16 is provided on the downstream side (upper side) of the flow passage 49 of the eliminator device 15 and on the upstream side (lower side) of the air supply port 6, and negative pressure is generated in the housing 3. Thus, the sterilization target air 8 that has flowed into the housing 3 from the air inlet 5 and passed through the flow passage 49 of the eliminator device 15 is forcibly sent out from the air inlet 6 to the outside of the housing 3.

  The fan device 16 is a sirocco fan, and is formed in the fan case 52 and a cylindrical impeller 53 rotatably provided in the fan case 52, a rotation driving device 54 such as an electric motor that rotationally drives the impeller 53, and the fan case 52. The suction port 55 and the discharge port 56 are provided. The impeller 53 has a large number of blades. The suction port 55 is formed on the back surface (rear surface) of the fan case 52, and the downstream side of the eliminator device 15 and the inside of the fan case 52 communicate with each other via the suction port 55. The discharge port 56 is formed on the upper surface of the fan case 52, and the inside of the fan case 52 and the air supply port 6 communicate with each other via the discharge port 56.

As shown in FIGS. 1 and 2, the fan device 16 is located closer to the left end side (an example closer to one end side) of the eliminator device 15 in the direction B of the pitch P of the bent plate 48.
Further, the blowing direction C of the sterilization target air 8 that passes through the flow passage 49 of the eliminator device 15 and blows downstream is within the plane orthogonal to the rotational axis 57 of the impeller 53, and the suction port 55 of the fan device 16. This is the direction away from the position, that is, the right end side (an example of the other end side) of the eliminator device 15.

  Further, as shown in FIG. 4, a control device 26 responsible for the operation of the air cleaning device 1 is provided on the front surface of the door body 4. The control device 26 has a functional circuit that takes charge of the low-speed operation mode and the high-speed operation mode, and controls the rotational speed of the rotational drive device 54 of the fan device 16 by operating a switch or the like, thereby changing the operation mode to the low-speed operation mode. And switch to high-speed operation mode.

Hereinafter, the operation of the above configuration will be described.
By operating a switch or the like and the control device 26 operates by switching the air cleaning device 1 to the low speed operation mode, the impeller 53 of the fan device 16 rotates at a low speed, and the sterilization target air 8 flows from the intake port 5. After being sucked into the housing 3 and flowing through the purification air passage 9 at a low flow rate, the air is sent out from the air inlet 6 into the room.

  At this time, the sterilizing agent solution 18 in the circulation tank 22 is supplied to the spraying device 14 by the circulation pump 24, and the spraying device 14 is applied to the sterilization target air 8 flowing from the upstream side to the downstream side through the purification vent 9. The sterilizing agent solution 18 is sprayed from.

  By this spraying, foreign substances such as airborne bacteria and dust contained in the sterilization target air 8 collide with the sprayed water of the sprayed germicide solution 18 and are captured and sterilized. Further, the spray water of the bactericide solution 18 that has reached the medium 13 causes the floating bacteria and dust attached to the medium 13 to flow down, and takes in foreign substances such as the floating bacteria and dust contained in the sterilization target air 8 to circulate the tank. 22 flows in.

  The sterilization target air 8 that has passed through the medium 13 is supplied to the eliminator device 15, flows into the inside from the inflow opening 35 of the eliminator case 30, and moves the capture member 40 of the low flow velocity eliminator 31 from below (upstream side) upward. (Downstream side), and then passes through the plurality of flow passages 49 of the high flow velocity eliminator 32 from below (upstream side) to above (downstream side) and upward (downstream side) from the outflow opening 36 of the eliminator case 30 ).

  At this time, when the low-flow-rate sterilization target air 8 passes through a minute opening of the mesh of the capture member 40 of the low-flow eliminator 31, fine particles D such as water droplets in the sterilization-target air 8 enter the capture member 40. Collided and captured. Furthermore, the fine particles D such as water droplets trying to pass through the minute opening of the capturing member 40 adhere to and aggregate with the fine particles D already captured at the peripheral edge of the opening of the capturing member 40. It is captured by the aggregating action and grows into fine particles D such as large water droplets.

  The low-flow-rate sterilization target air 8 that has passed through the low-flow-rate eliminator 31 thus flows through the plurality of flow passages 49 of the high-flow-rate eliminator 32 from below to above. At this time, as shown in FIG. 6, the fine particles D such as water droplets in the sterilization target air 8 cannot be bent due to inertia and are caught by inertia collision with the surface of the bent plate 48.

When the sterilization target air 8 has a low flow rate, the fine particles D in the sterilization target air 8 are small and weak in inertia, and thus are separated and removed mainly by the low flow rate eliminator 31 as described above. .
Further, by operating a switch or the like, the control device 26 operates the air purifier 1 by switching to the high speed operation mode, whereby the impeller 53 rotates at a high speed, and the sterilization target air 8 passes from the intake port 5 to the housing 3 The air is sucked in and flows through the purification air passage 9 at a high flow rate, and then is sent out from the air supply port 6. When the sterilization target air 8 passes through the minute opening of the capturing member 40 of the low flow rate eliminator 31, the sterilization target air 8 has a high flow rate, so that the fine particles D such as water droplets in the sterilization target air 8 are Although it is easy to pass through the minute opening of the capturing member 40 of the low flow eliminator 31 together with the sterilization target air 8, it passes through the flow passage 49 of the high flow eliminator 32 even if it passes through the low flow eliminator 31. At times, the flow path 49 cannot be bent because it tends to go straight due to inertial force, and is caught by inertial collision with the surface of the bent plate 48.

  The fine particles D in the high flow velocity sterilization target air 8 adhere to the fine particles D such as water droplets captured at the peripheral portion of the opening when passing through the opening of the capturing member 40 of the low flow eliminator 31. Then, it grows into large fine particles D and drops downward by gravity. If not dripping, the particles D flow from the low flow velocity eliminator 31 to the flow passage 49 of the high flow velocity eliminator 32 in a large state, so that the inertial force becomes strong and the inertial collision easily occurs. Thus, separation and removal are performed mainly by the high flow rate eliminator 32.

  Further, when the low speed operation mode is switched to the high speed operation mode, even if the fine particles D captured by the capturing member 40 of the low flow velocity eliminator 31 are blown downstream (upward), the blown fine particles D are still downstream. The high flow velocity eliminator 32 provided in the

  In this way, fine particles D such as water droplets in the low flow rate sterilization target air 8 are separated and removed mainly by the low flow rate eliminator 31, and fine particles D such as water droplets in the high flow rate sterilization target air 8 are mainly used. Since it is separated and removed by the high flow rate eliminator 32, it is possible to cope with the sterilization target air 8 having a wide flow rate from the low flow rate sterilization target air 8 to the high flow rate sterilization target air 8.

  In addition, since a plurality of crests 43 and troughs 44 are alternately formed on the capture member 40 of the low flow velocity eliminator 31, the area of the capture member 40 can be increased, and the sterilization target air 8 is captured. The flow rate when passing through the minute opening of the member 40 decreases.

  In addition, water droplets (an example of the fine particles D) captured by the capturing member 40 and water droplets captured by the bent plate 48 and flowing down from the surface of the bent plate 48 to the capturing member 40 are valley portions 44 along the slope of the peak portion 43. Therefore, the formation of a water film can be prevented, and the surface of the capturing member 40 is not covered with the water film. By such a thing, the pressure loss at the time of the sterilization object air 8 passing the low flow rate eliminator 31 can be reduced.

  Further, the water droplets captured by the capturing member 40 flow down toward the rear end of the low flow velocity eliminator 31 due to the inclination of the eliminator device 15. Thereby, the drainage of the capture member 40 is improved.

Moreover, since the capture member 40 is a wire mesh having a plurality of peak portions 43 and valley portions 44, the surface of the capture member 40 can be easily cleaned using a brush or the like.
Further, since the high flow rate eliminator 32 is mounted and supported on the frame frame 39 of the low flow rate eliminator 31 in the eliminator case 30, the structure of the eliminator device 15 is simplified.

  Even in the case of operating in the high-speed operation mode, the medium performance filter 12 is gradually clogged, so that the sterilization target air 8 passing through the eliminator device 15 decreases from a high flow rate to a low flow rate. Even in such a case, fine particles D such as water droplets in the sterilization target air 8 can be reliably separated and removed by the eliminator device 15.

  The sterilization target air 8 that passed through the eliminator device 15 in this way was sucked into the fan case 52 from the suction port 55 of the fan device 16 and flowed in the fan case 52 as shown in FIGS. Thereafter, the air is discharged from the discharge port 56 to the outside of the fan case 52 and blown out from the air supply port 6.

  Here, since the blowing direction C of the sterilization target air 8 that passes through the flow passage 49 of the eliminator device 15 and blows downstream is directed in the direction away from the position of the suction port 55 of the fan device 16 (upper right direction) When the sterilization target air 8 that has flowed through the flow passage 49 is blown downstream from the flow passage 49, the air 8 is reversed toward the suction port 55 of the fan device 16, and the flow direction is greatly changed (changed in direction). For this reason, the possibility that the particulates D contained in the sterilization target air 8 immediately before being blown downstream from the flow passage 49 collides with the bent plate 48 and is captured is increased. Thereby, the capture performance of the eliminator device 15 that captures the fine particles is improved.

  In the above embodiment, a wire mesh (mesh) is used as the capturing member 40 of the low flow rate eliminator 31, but it may be formed by weaving resin or metal fibers into a cloth shape, or many A breathable member having a minute opening may be used.
