The notification unit includes, for example, a plurality of display lamps, and can visually notify the user of the operating state of the humidified air cleaner 1 by turning on and off the display lamps.

The front surface 2A of the cabinet 2 is constituted by the front panel 10. The front panel 10 constitutes a part of the outer box of the humidified air cleaner 1. Details of the configuration of the front panel 10 will be described later.

An opening is formed in the back surface 2B of the case 2, and the rear panel 20 is attached so as to close the opening. On the rear panel 20, a plurality of vents 21 are formed. The vent 21 is formed through the substantially flat rear panel 20 in the thickness direction. The vent 21 is a small hole for introducing outside air into the interior of the cabinet 2 of the humidified air cleaner 1. A recess 22 is formed in the rear panel 20. The user of the humidified air cleaner 1 can remove the rear panel 20 from the back surface 2B of the cabinet 2 by inserting a finger into the recess 22 and pulling the rear panel 20 to the rear.

A concave portion 24 is formed on the right side surface 2C of the case 2. A recess 25 is formed on the left side surface 2D of the case 2. The user of the humidified air cleaner 1 can insert the finger of one hand into the recess 24 and insert the finger of the other hand into the recess 25 to lift the box 2. Thereby, the humidified air cleaner 1 is moved to a position far away from the floor, and the humidified air cleaner 1 can be easily moved to an appropriate position indoors.

A cover 26 is provided on the left side 2D of the case 2. The cover 26 is formed to be removable from the left side 2D. In the state where the cover 26 is taken out, it becomes possible to take out the high-pressure generating unit 100 described later from the humidified air cleaner 1 or attach it to the humidified air cleaner 1. A water storage tray 30 is arranged at the lower part of the humidified air cleaner 1. The water storage tray 30 is configured to be removable in the left direction from the left side 2D.

Fig. 5 is a longitudinal sectional view showing the internal structure of the humidified air cleaner 1 shown in Fig. 1. In FIG. 5, the cross section of the humidified air cleaner 1 viewed from the side (left side) is shown.

As shown in FIG. 5, a filter 41 is arranged in front of the rear panel 20. The filter 41 is an integrated dust collection / deodorization filter that traps fine dust and absorbs odorous components in the air. Instead of the integrated filter 41, the dust collection filter and the deodorizing filter may be configured separately and arranged to overlap each other.

The filter 41 is housed inside the case 2 and covers the rear with the rear panel 20. By taking out the rear panel 20, it becomes an arrangement which can easily enter and exit the filter 41. Thus, maintenance work such as cleaning or replacement of the filter 41 becomes easy.

In front of the filter 41, that is, closer to the inside of the case 2 than the filter 41, a hollow descending air path 150 is formed.

The water storage tray 30 has a tray body 31. The tray body 31 has a container-like shape, and stores water inside. Inside the tray body 31, a humidification filter 32, an antibacterial agent 33, and a float 34 are arranged.

The humidification filter 32 has water absorption and air permeability. The lower part of the humidification filter 32 is immersed in the water already stored in the tray body 31. The upper part of the humidification filter 32 protrudes upward from the water surface, and is arranged in the air. The humidification filter 32 has a water immersion portion immersed in water in the tray body 31 at the lower portion, and a non-water immersion portion not immersed in water at the upper portion.

The humidification filter 32 sucks up the water in the tray body 31 by the capillary phenomenon, and the whole is in a state containing water. Although the non-immersion part of the upper part of the humidification filter 32 is not immersed in water, by absorbing water from the immersion part of the lower part, regardless of the amount of water stored in the tray body 31, moisture is distributed throughout the humidification filter including the non-immersion part 32 overall.

The antibacterial agent 33 is immersed in the water that has been stored in the tray body 31. The antibacterial agent 33 contains an antibacterial component. By dissolving the antibacterial component in the water stored in the tray body 31, the antibacterial function of suppressing the generation of bacteria or mold in the water in the tray body 31 and the humidification filter 32 is exerted.

The float 34 floats as the water level in the tray body 31 changes. The float 34 constitutes a water level sensor that detects the water level in the tray body 31. The float 34 is provided with a magnet, for example. Based on the water level in the tray body 31 detected by the water level sensor, the operation of the humidified air cleaner 1 is controlled.

Inside the box 2, a blower 50 is arranged. The water storage tray 30 is arranged below the blower 50. The blower 50 is isolated from the filter 41 and is arranged in front of the filter 41. The downdraft 150 is formed between the blower 50 and the filter 41 in the front-rear direction.

The blower 50 includes a fan 52 that blows gas, a fan motor 53 that is a motor that rotationally drives the fan 52, and a fan case 54 that houses the fan 52 and the fan motor 53. The fan case 54 has an opposing surface 56 facing the front panel 10. The facing surface 56 is arranged to be isolated from the front panel 10.

Between the front panel 10 and the opposing surface 56 of the fan casing 54, a hollow upstream air passage 160 that is a passage through which air flows to the fan 52 is formed is formed. The upstream air passage 160 constitutes a part of the passage closer to the upstream side of the fan 52 in the passage where the air blown by the fan 52 flows. The front panel 10 constitutes a part of the wall surface of the upstream air passage 160 that is the air passage of the gas blown by the fan 52.

A plurality of ribs 80 are attached to the opposite surface 56 of the fan casing 54. The rib 80 is disposed between the facing surface 56 of the fan case 54 and the front panel 10. The rib 80 extends forward from the facing surface 56 of the fan casing 54 toward the front panel 10.

The downstream air path 170 which is a passage through which the air flowing from the fan 52 flows is formed above the fan 52. The downstream air path 170 constitutes a part of the path closer to the downstream side of the fan 52 in the path where the air blown by the fan 52 flows. In the branching part 180, the air path diverges into Two paths are connected to the front air path 183 of the front air outlet 3 and the rear air path 184 of the rear air outlet 4. The front air outlet 3 is provided at the upper end of the front air passage 183. The rear air outlet 4 is provided at the upper end of the rear air passage 184. The front air outlet 3 and the rear air outlet 4 are provided at the downstream end of the air flow blown by the fan 52.

The downstream air path 170 is provided with a high-pressure generating unit 100. The high-pressure generating unit 100 protrudes into the downstream air path 170 from the wall surface of the downstream air path 170. The high-voltage generating unit 100 generates active species such as ions by discharge. As a result, the air flowing through the high-pressure generating unit 100 contains the active species.

The air that has flowed into the inside of the cabinet 2 through the filter 41 is blown to the water storage tray 30 provided below the humidified air cleaner 1 through the downflow path 150. The air is humidified by passing the humidifying filter 32 that has absorbed water. Thereafter, the humidified air is blown to the blower 50. The rotation of the fan 52 circulates air. The downstream air path 170 contains active species in the air. Then, the humidified air containing the active species is discharged from the front air outlet 3 and the rear air outlet 4 to the outside (indoor).

Fig. 6 is a perspective view showing the internal structure of the humidified air cleaner 1 shown in Fig. 1. The front panel 10 is not configured to be removable from the humidified air purifier 1. Although it is actually impossible to remove only the front panel 10 from the assembled humidified air purifier 1, it is illustrated in FIG. 6 for convenience The front panel 10 is not attached to the humidified air cleaner 1 obliquely seen from the front left.

A buoy position detection substrate 91 is arranged at the center in the left-right direction closer to the front than the water storage tray 30. The buoy position detection substrate 91 constitutes a circuit board arranged at a position adjacent to the water storage tray 30 in the front-rear direction. The pontoon position detection substrate 91 is configured to have a Hall IC, for example. The buoy position detection substrate 91 detects the height position of the buoy 34 in the tray body 31 to detect The water level in the tray body 31. The pontoon position detection substrate 91, together with the buoy 34, constitutes a water level sensor that detects the water level in the tray body 31.

A right rib 92 for reinforcement is arranged closer to the right than the pontoon position detection substrate 91. The right rib 92 is arranged in front of the water storage tray 30 in the same way as the float position detection substrate 91. The pontoon position detection substrate 91 and the right rib 92 are arranged along the front edge portion of the tray body 31. The right rib 92 is inclined with respect to the up-down direction in such a manner that the position in the up-down direction becomes lower as it goes to the right, that is, as it moves away from the float position detection substrate 91. The right rib 92 is inclined to the lower right.

A left rib 93 for reinforcement is arranged closer to the left than the pontoon position detection substrate 91. The left rib 93 is arranged in front of the water storage tray 30 in the same way as the float position detection substrate 91. The pontoon position detection substrate 91 and the left rib 93 are arranged along the front edge portion of the tray body 31.

The left rib 93 is inclined to the lower left.

The vertical rib 94 for supporting the right rib 92 to increase strength is arranged to extend in the vertical direction. Since the right rib 92 is inclined, the right rib 92 and the longitudinal rib 94 are not orthogonal, and form an angle slightly deviating from a right angle. The vertical rib 94 for supporting the left rib 93 to increase its strength is arranged to extend in the vertical direction. Since the left rib 93 is inclined, the left rib 93 and the longitudinal rib 94 are not orthogonal, and form an angle slightly deviating from a right angle.

On the opposite surface 56 of the fan casing 54, an air inlet 57 to the fan 52 is formed. The suction port 57 viewed from the front has a substantially circular shape. The plurality of ribs 80 attached to the facing surface 56 of the fan casing 54 are arranged at intervals along the periphery of the air inlet 57. The plurality of ribs 80 are arranged upstream of the suction port 57 in the flow direction of the gas toward the suction port 57.

A plurality of water molecules based on negative oxygen ions (O ₂ ^-) of the aggregate cluster around ions, to _{^{O 2 - (H 2 O)}} n (n is an arbitrary integer not less than 0). When positive ions and negative ions are released into the room, the two ions surround the mold or virus floating in the air, causing a chemical reaction with each other on their surfaces. By the action of the hydroxyl radical (‧OH) of the active species generated at this time, the planktonic mold etc. are removed.

The high-voltage generating unit 100 includes electrode protection parts 104 and 106 that protect the front ends of the discharge parts 102 and 103. The electrode protection part 104 and the electrode protection part 106 are arrange | positioned at intervals. The electrode protection parts 104 and 106 are provided adjacent to the discharge parts 102 and 103 in order to prevent external objects from directly contacting the discharge parts 102 and 103. Discharge parts 102 and 103 are arranged between the electrode protection part 104 and the electrode protection part 106. The electrode protection part 104 and the electrode protection part 106 sandwich the discharge parts 102 and 103.

The electrode protection parts 104 and 106 are integrally formed with the unit case 101 and protrude from the unit case 101. The electrode protection parts 104 and 106 protrude from the unit case 101 to be larger than the discharge parts 102 and 103.

The electrode protection portion 104 has a beam portion 105A and pillars 105B to 105D. The pillars 105B to 105D vertically protrude from the unit box 101. The extending direction of the pillars 105B to 105D is parallel to the extending direction of the discharge parts 102 and 103. The beam portion 105A is coupled to the front ends of the pillars 105B to 105D. The pillar 105B is coupled to one end of the beam portion 105A, the pillar 105D is coupled to the other end of the beam portion 105A, and the pillar 105C is coupled to the central portion of the beam portion 105A. The pillar 105B and the pillar 105C are arranged with an interval, and the pillar 105C and the pillar 105D are arranged with an interval.

The electrode protection portion 106 has a beam portion 107A and pillars 107B to 107D. The pillars 107B to 107D vertically protrude from the unit box 101. The extending direction of the pillars 107B to 107D is parallel to the extending direction of the discharge parts 102 and 103. The beam portion 107A is coupled to the front ends of the pillars 107B to 107D. The pillar 107B is coupled to one end of the beam portion 107A, the pillar 107D is coupled to the other end of the beam portion 107A, and the pillar 107C is coupled to the central portion of the beam portion 107A. The pillar 107B and the pillar 107C are arranged with an interval, and the pillar 107C and the pillar 107D are arranged with an interval.

In a state where the high-pressure generating unit 100 has been installed in the downstream air passage 170 (FIG. 5) of the humidified air cleaner 1, the electrode protection portion 104 is disposed at the relatively discharge portion 102 in the flow direction of air passing through the high-pressure generating unit 100 103 is near the upstream. The electrode protection portion 106 is arranged downstream of the air flow than the discharge portions 102 and 103. The pillars 105B to 105D and 107B to 107D are arranged at positions that do not overlap with the discharge parts 102 and 103 in the air flow direction. The beam portions 105A and 107A extend in a direction orthogonal to the flow direction of air.

The unit box 101 of the high-voltage generating unit 100 is held by the holder 110. The unit box 101 can be mounted on the holder 110. The unit box 101 is configured to be freely attachable to and detachable from the holder 110.

The holder 110 is attached to the holder receiver 130. The holder 110 is configured to be freely attachable to and detachable from the holder receiver 130. The holder receiving portion 130 is attached to the cabinet 2 (FIGS. 1 to 5) of the humidified air cleaner 1 and is accommodated inside the cabinet 2.

The ion amount detection substrate 120 shown in FIGS. 6 and 9 is mounted on the holder receiving part 130. The ion amount detection substrate 120 detects the concentration of active species (ions) generated by the discharge by detecting the magnetic fields generated by the discharge parts 102 and 103. The ion amount detection substrate 120 is arranged in the vicinity of the discharge parts 102 and 103 so that the concentration of the active species (ions) can be accurately measured.

The holder receiving portion 130 is formed with an insertion port. The holder 110 is inserted into the holder receiver 130 through the insertion port, and thus is attached to the holder receiver 130. The insertion port is covered by the cover 26 (FIGS. 2 and 6). In a state where the lid 26 is attached to the case 2, the holder receiving portion 130 and the holder 110 are covered by the lid 26 without being exposed to the outside. The lid 26 is removed from the case 2 and the insertion opening of the holder receiving portion 130 is exposed to the outside, and the holder 110 and the unit box 101 can be installed to the holder receiving portion 130 or the insertion opening through the insertion opening. Take out from the holder receiving part 130.

As shown in FIGS. 6 and 9, the direction in which the holder 110 and the unit box 101 are inserted into the holder receiver 130 does not match the left-right direction of the humidified air cleaner 1. The holder 110 and the unit case 101 are inserted in the direction of the holder receiving part 130, and are cleaned with respect to the humidified air so that the holder 110 and the unit case 101 are inserted in the holder receiving part 130 and face forward The machine 1 is inclined in the left-right direction. Among the discharge parts 102 and 103, the discharge part 103 is inserted deeper into the inside of the case 2 from the insertion port of the holder receiving part 130.

Therefore, in a state where the holder 110 and the unit case 101 are accommodated in the case 2, the discharge part 102 is arranged closer to the rear than the discharge part 103, and the discharge part 103 is arranged closer to the front than the discharge part 102. In addition, since the cover 26 is provided on the left side 2D of the case 2, the holder 110 and the unit In a state where the case 101 is housed in the case 2, the discharge part 102 is arranged closer to the left than the discharge part 103, and the discharge part 103 is arranged closer to the right than the discharge part 102.

FIG. 16 is a schematic diagram showing the flow of gas in the downstream air path 170. In FIG. 16, a part of the interior of the cabinet 2 of the humidified air cleaner 1 seen through from behind is shown. The right direction in the figure is the right direction of the humidified air cleaner 1, and the left direction in the figure is the left direction of the humidified air cleaner 1. The arrows in the figure indicate the rotation direction of the fan 52 and the fan motor 53.

The fan case 54 has air passage wall surfaces 172 and 174 that define the downstream air passage 170 (see also FIG. 10). The air passage wall surfaces 172 and 174 are inclined with respect to the up-down direction of the humidified air cleaner 1 so as to face upward as they face upward. Since the fan 52 rotates clockwise in FIG. 16, the air flowing from the fan 52 to the downstream air path 170 flows more into the vicinity of the air path wall surface 172 and flows through the air near the air path wall surface 172 The flow rate becomes larger. By arranging the air passage wall surface 172 obliquely with respect to the up-down direction, the imbalance of the air flow rate and the flow velocity of the air in the left-right direction of the humidified air cleaner 1 in the downstream air passage 170 is reduced, and the discharge parts 102 and 103 flow The flow of air increases.

Among the discharge parts 102 and 103, the discharge part 102 is arranged further back, and the discharge part 103 is arranged further forward. Therefore, the positive ions generated in the discharge part 102 mostly flow to the rear in the downstream air passage 170, and the negative ions generated in the discharge part 103 flow mostly to the front in the downstream air passage 170. The concentration of positive and negative ions in the downstream air path 170 is caused by the imbalance in the front-rear direction of the humidified air cleaner 1.

As a result, a lot of negative ions are contained in the air flowing into the front air path 183 and flowing out of the front air outlet 3 to the outside of the device, and a lot of air is flowing into the rear air path 184 and flowing out of the rear air outlet 4 from the outside of the device Positive ions. As described above, in the humidified air cleaner 1, the airborne mold and virus in the air are removed by the chemical reaction of positive ions and negative ions. Therefore, when empty When the concentration imbalance between positive ions and negative ions contained in the air is large, the air purification ability to remove airborne mold and viruses cannot be fully exerted.

The humidified air cleaner 1 of the fourth embodiment is used to solve such a situation. 17 and 18 are perspective views showing the configuration in the downstream air path 170 of the fourth embodiment. FIG. 17 illustrates a part of the internal structure of the cabinet 2 of the humidified air cleaner 1 obliquely viewed from the left rear, and FIG. 18 illustrates the cabinet 2 of the humidified air cleaner 1 obliquely viewed from the front left Part of the internal composition. As shown in FIGS. 17 and 18, in the humidified air cleaner 1 of the fourth embodiment, a baffle (vane ) 200. The baffle 200 is provided at the branch 180.

FIG. 19 is a perspective view showing details of the configuration of the baffle 200. FIG. The baffle 200 extends in the left-right direction of the humidified air cleaner 1 and is fixed to the branch portion 180. The baffle 200 has a left edge 201, a front edge 202, and a right edge 203. The length of the left edge portion 201 is not equal to the length of the right edge portion 203, and the left edge portion 201 is formed longer than the right edge portion 203. The left and right heights of the baffle 200 are different. The front end edge portion 202 is inclined with respect to the vertical direction. The left edge portion 201 protrudes from the branch portion 180 into the downstream air passage 17 more than the right edge portion 203.

As shown in FIG. 17, the discharge parts 102 and 103 are arranged in front of the baffle 200. The air containing many positive ions generated in the discharge part 102 passes near the discharge part 102 and flows toward the left edge 201 of the baffle 200. The air containing many negative ions generated in the discharge part 103 passes near the discharge part 103 and flows toward the right edge part 203 of the baffle 200.

The air containing ions passing through the discharge parts 102 and 103 provided on the front side of the inner wall surface of the downstream air path 170 flows toward the rear air path 184 by the baffle 200 protruding into the downstream air path 170 from the branch 180. Obstructed. In the baffle 200, a portion near the left edge portion 201 protrudes longer into the downstream air path 170. Therefore, the air containing many positive ions generated in the discharge part 102 is stronger The rectifying action of the baffle 200 which is intended to allow air to flow into the forward air path 183 is received. On the other hand, the rectification effect of the baffle 200 received by the air containing many negative ions generated in the discharge part 103 becomes relatively small. As a result, the inflow of positive ions into the front air passage 183 is promoted, and the inflow of negative ions into the rear air passage 184 is promoted.

In this way, the baffle 200 adjusts the flow rate of positive and negative ions flowing into the front air passage 183 and the rear air passage 184. The concentration imbalance between positive ions and negative ions contained in the air flowing into the front air path 183 is reduced, and the concentration imbalance between the positive ions and negative ions contained in the air flowing into the rear air path 184 is reduced. Since the concentration of positive ions and negative ions contained in the air blown from both the front air outlet 3 and the rear air outlet 4 can be uniformized, the ability to remove airborne mold and viruses by the humidified air cleaner 1 can be improved .

(Embodiment 5)

FIG. 20 is a side view of the configuration in the downstream air path 170 of the fifth embodiment. The humidified air cleaner 1 of the fifth embodiment is different from the fourth embodiment in that the baffle 200 has the rotating shaft 210. The fan 200 of the fifth embodiment is provided so as to be rotatable around the rotating shaft 210. The rotating shaft 210 is arranged at a branch portion 180 where the front air path 183 and the rear air path 184 diverge from the downstream air path 170.

By rotating the baffle 200 to change the angle, the flow rate of the air flowing into the front air passage 183 and the rear air passage 184 fluctuates. By adjusting the angle of the baffle 200, the flow rate of the air flowing into the front air passage 183 and the rear air passage 184 is adjusted. To the position shown by the broken line in FIG. 20 to the position shown by the solid line, the baffle 200 is rotated counterclockwise in FIG. 20, and the baffle 200 is moved backward, thereby sending the air to the front air outlet 3 Increased traffic. Alternatively, the baffle 200 is rotated clockwise in FIG. 20 and moved forward, whereby the flow rate of the air sent to the rear outlet 4 increases. In this way, the baffle 200 can adjust the flow rate ratio of the air sent to the front air outlet 3 and the rear air outlet 4.

Next, the operation and effect of the humidified air cleaner 1 of the embodiment will be described. In the humidified air cleaner 1, noise caused by the operation of the fan 52 and the fan motor 53 is easily transmitted to the front of the blower 50. In the humidified air cleaner 1 of the embodiment, as shown in FIGS. 1 and 5, the front panel 10 constitutes a part of the cabinet 2 and constitutes a part of the wall surface of the upstream air passage 160 that is a blowing path of air blown by the fan 52, And it has a function as an outline member of an embodiment. The front wall surface of the upstream air path 160 formed in front of the blower 50 is configured by the front panel 10 which is a part of the cabinet 2, so noise is easily transmitted to the cabinet 2 (front panel 10).

Therefore, in the humidified air cleaner 1 of the embodiment, as shown in FIGS. 6 and 9, the sound absorbing material 70 is sandwiched and supported by the front panel 10 and the support member 63. The propagation of the sound generated by the fan 52 transmitted to the front panel 10 is suppressed by the sound absorbing material 70. In addition, the vibration of the cabinet 2 is also suppressed by the sound absorbing material 70. Therefore, according to the humidified air cleaner 1 of the embodiment, the noise can be reduced and the vibration of the cabinet 2 can be reduced.

As shown in FIGS. 6 and 9, the sound absorbing material 70 is sandwiched and supported by the front panel 10 and the upper wall member 61. In addition to the space between the front panel 10 and the support member 63, the sound absorbing material 70 is also provided between the front panel 10 and the upper wall member 61, so that noise and vibration of the cabinet 2 can be more reliably reduced.

In addition, as shown in FIG. 5, in the humidified air cleaner 1 of the embodiment, a front air outlet 3 and a rear air outlet 4 for blowing air to the outside are formed in the upper portion of the cabinet 2. The downstream air path 170 where the air flowing out of the blower 50 flows is provided above the blower 50. At the entrance of the downstream air path 170 where the air flow sent from the fan 52 intersects, noise is also likely to occur. Therefore, as shown in FIG. 9, the sound absorbing material 70 has a portion arranged above the fan motor 53. By arranging the sound absorbing material 70 near the base portion of the downstream air path 170 where noise is generated, the noise can be reduced more effectively.

In addition, as shown in FIG. 5, the water storage tray 30 is disposed at the lower portion of the cabinet 2. Water is stored in the water storage tray 30. In the event that the humidified air purifier is toppled over, there is a possibility that the remaining water in the water storage tray 30 flows toward the upper side of the tank 2. Therefore, in the embodiment of humidified air In the cleaning machine 1, as shown in FIG. 9, the sound absorbing material 70 is arranged above the water storage tray 30 and below the power supply substrate 90. The sound absorbing material 70 can function as a water absorbing material, and the water reaching the sound absorbing material 70 is absorbed by the sound absorbing material 70. Thereby, since the sound absorbing material 70 can be prevented from infiltrating into the area above the sound absorbing material 70, the reliability of the power supply substrate 90 disposed above the sound absorbing material 70 can be improved.

In addition, as shown in FIG. 6, in order to reduce the ventilation resistance to the air flow flowing into the fan 52 and reduce the pressure loss, no grid is provided in the air inlet 57. By reducing the pressure loss, the efficiency of the fan motor 53 is improved, and it has the effects of quieting the same air volume and reducing power consumption. Since the front panel 10 is configured not to be taken out, it cannot be accessed from the front toward the air inlet 57 even if no grid is provided.

On the other hand, the water storage tray 30 is configured to be removable. In a state where the water storage tray 30 has been removed, the user of the humidified air cleaner 1 can insert his hand into the hollow space below the blower 50. In order to prevent the user of the humidified air cleaner 1 from contacting the fan 52, it is necessary to restrict access to the intake port 57 from below.

Therefore, as shown in FIG. 6, the humidified air cleaner 1 of the embodiment is provided with a plurality of arrays arranged along the circumference of the intake port 57 on the upstream side of the intake port 57, that is, on the lower side of the intake port 57. Rib 80. By appropriately setting the interval between adjacent ribs 80 and the length of the rib 80 in the air flow direction, it is possible to realize a configuration in which the user cannot insert a finger above the rib. This can prevent the user's finger from reaching the fan 52.

In order to arrange the rib 80 below the intake port 57, the rib may be provided on the back of the front panel 10. However, the front panel 10 is a resin molded product constituting the outer box of the device. When a rib is to be formed on the back of the front panel 10, due to shrinkage after molding, local depressions are likely to occur on the front side of the position corresponding to the ribs, and this depression is not preferable because it affects the appearance. Yu Yi During the molding of the front panel 10, the manufacturing process of the front panel 10 is increased, resulting in an increase in manufacturing costs. Alternatively, although the ribs may be formed separately from the front panel 10 and the fan case 54, in this case, the number of parts increases, which increases the cost.

Therefore, in the humidified air cleaner 1 of the embodiment, as shown in FIGS. 6 and 10, a plurality of ribs 80 are attached to the fan casing 54 and extend toward the front panel 10. Since the fan case 54 is a member accommodated in the case 2, the rib does not affect the appearance of the humidified air cleaner 1. Since it is not necessary to provide the rib as a separate member, the manufacturing cost can be reduced.

As shown in FIGS. 10 and 11, the thickness of the rib 80 decreases as it approaches the upstream end in the flow direction of air toward the intake port 57, and decreases as it approaches the downstream end in the flow direction of air. By making the rib 80 into a wing shape as described above, it is possible to reduce the pressure loss of the flow of air passing between the ribs 80.

In addition, in the case where the ribs 80 arranged along the circumference of the intake port 57 are only one row, in order to reliably prevent the intrusion of fingers, it is necessary to narrow the interval of the ribs 80 or increase the thickness of the ribs 80. In this case, the effect of reducing pressure loss becomes smaller. When resin molding the rib 80 having a large thickness, it is necessary to make the molding time long.

Therefore, in the humidified air cleaner 1 of the embodiment, as shown in FIGS. 10 and 11, the plurality of ribs 80 includes the first rib group 81 and the one disposed closer to the intake port 57 than the first rib group 81. The second rib group 86. The second rib 87 included in the second rib group 86 is disposed between two adjacent first ribs 82 among the first ribs 82 included in the first rib group 81. According to this, since the interval between the first ribs 82 can be widened and the cross-sectional area of the air flow path can be enlarged, the pressure loss can be reduced. Even if the finger intrudes into the gap 83 between the two adjacent first ribs 82, the second rib 87 prevents the intrusion before the first joint of the finger invades, so even if the interval between the first ribs 82 becomes wider Prevent finger intrusion.

The distance between the first ribs 82 in the direction along the peripheral edge of the intake port 57 may be 10 mm or more and 15 mm or less. If the interval between the first ribs 82 is less than 10 mm, the pressure loss of the air passing between the first ribs 82 becomes larger. If the interval between the first ribs 82 exceeds 15 mm, the fingers easily enter the gap 83 between the first ribs 82. Since the force in the direction in which the gap 83 widens may act on the first ribs 82, the user's fingers may reach Fan 52 is at risk.

The offset distance of the second rib group 86 in the vicinity of the intake port 57 from the first rib group 81 is set to correspond to the length of the user's finger from the fingertip to the first joint. For example, the offset distance may be 10 mm or more and 30 mm or less. The offset distance may be 15 mm or more and 20 mm or less.

As shown in FIG. 11, the side surface 84 of the downstream end 82B of the first rib 82 and the side surface 89 of the upstream end 87A of the second rib 87 face each other. The angle at which the side surface 84 of the first rib 82 is inclined with respect to the extending direction of the first rib 82 is equal to the angle at which the side surface 89 of the second rib 87 is inclined with respect to the extending direction of the second rib 87, and the first The side surface 84 of the rib 82 and the side surface 89 of the second rib 87 can reduce the pressure loss of the air flowing from the gap 83 between the first ribs 82 to the gap 88 between the second ribs 87.

The distance between the side surface 84 of the first rib 82 and the side surface 89 of the second rib 87 may be 6 mm at the base of the rib and 7 mm at the front end of the rib.

Also, as shown in FIG. 11, the side surface 84 of the downstream end 82B of the first rib 82 is inclined at an angle of 30 ° or less with respect to the extending direction of the first rib 82, and the side surface 89 of the upstream end 87A of the second rib 87 is relative to The angle in which the extending direction of the second rib 87 is inclined is 30 ° or less. If the inclination angle of the side surface 84 of the first rib 82 and the side surface 89 of the second rib 87 exceeds 30 °, air flowing through the gap 83 between the first ribs 82 or the gap 88 between the second ribs 87 Peeling occurs, eddy currents are generated, and the pressure loss increases. By setting the inclination angle to 30 ° or less, it is possible to suppress the occurrence of peeling and reduce the pressure loss.

Further, as shown in FIG. 11, the plurality of first ribs 82 are arranged so that their extending directions are parallel to each other. By arranging the first ribs 82 as described above, since the gaps 83 between the first ribs 82 are formed equally, it is possible to more reliably prevent the user's finger from being inserted through the gaps 83.

Further, as shown in FIG. 12, among the plurality of first ribs 82 and second ribs 87 arranged along the periphery of the air inlet 57, if the ribs located at one end of the row are compared, the diameter relative to the fan 52 Direction, the inclination angle of the second rib 87 is smaller than the inclination angle of the first rib 82. As described above, the first ribs 82 are preferably arranged in parallel. In this regard, the second rib 87 only needs to be able to prevent a finger intruding into the gap 83 of the first rib 82 at the upstream end 87A, and the extending direction of the second rib 87 may not be parallel to the extending direction of the first rib 82. By changing the angle between the extension direction of the second rib 87 and the radial direction of the fan 52 to be small, the air passing through the gap 88 between the second ribs 87 can be rectified so as to face the intake port 57. Therefore, the flow rate of air guided to the intake port 57 can be increased.

As shown in FIG. 6, adjacent to the water storage tray 30, a buoy position detection substrate 91 that detects the water level in the water storage tray 30, and a right rib 92 and a left rib 93 are disposed. The right rib 92, the float position detection substrate 91, and the left rib 93 are arranged in this order. The right rib 92 and the left rib 93 are inclined with respect to the up-down direction so that the position in the up-down direction becomes lower as they move away from the float position detection substrate 91.

The pontoon position detection substrate 91 is arranged below the water surface of the water storage tray 30 when it is full of water in order to detect that the water in the water storage tray 30 decreases and / or the water in the water storage tray 30 disappears. In the case where the humidified air purifier is overturned in the event of a lapse, there is a possibility that the remaining water inside the water storage tray 30 flows toward the float position detection substrate 91. In the humidified air cleaner 1 of the embodiment, the right rib 92 and the left rib 93 are provided obliquely, whereby the water overflowing from the water storage tray 30 flows along the inclination of the right rib 92 and the left rib 93, which can be suppressed Spilled water immediately reaches the float position detection Substrate 91. Therefore, it is possible to avoid the submersion of the float position detection substrate 91 in a short time until the user of the humidified air cleaner 1 finds that it is overturned.

As shown in FIG. 6, a vertical rib 94 that intersects the right rib 92 is provided. A longitudinal rib 94 crossing the left rib 93 is provided. By providing the longitudinal rib 94, the strength of the right rib 92 and the left rib 93 can be improved.

In addition, as shown in FIG. 14, at the intersection of the right rib 92 and the vertical rib 94, a notch 95 is formed above the intersection of the vertical rib 94. When the water flowing along the inclination of the right rib 92 reaches the longitudinal rib 94, the notch 95 is formed, and the water further flows along the right rib 92 through the notch 95, so as to be further away from the float position detection substrate 91. Therefore, since it is possible to more restrain the water from reaching the pontoon position detection substrate 91, it is possible to more surely avoid flooding of the pontoon position detection substrate 91.

As shown in FIGS. 17 and 18, the downstream air path 170 where the discharge parts 102 and 103 are arranged diverges into a branch 180 of the front air path 183 and the rear air path 184, and a baffle 200 is provided. As shown in FIG. 19, the length of one edge in the extending direction of the baffle 200 is different from the other edge. The left edge portion 201 is formed longer than the right edge portion 203.

The air path of the air from the box 2 toward the air outlet diverges in the front-rear direction, and there may be the concentration of active species (ions) in the air flowing into the front air path and the air flowing into the air path on the rear side The concentration of the active species (ions) creates an imbalance. In the embodiment shown in FIG. 17, the discharge parts 102 and 103 are arranged in an oblique direction with respect to the left-right direction, thereby causing density imbalance. By providing baffles 200 with different heights on the left and right as shown in FIG. 19 at the branch portion of the air path where such concentration imbalance occurs, the concentration balance can be adjusted.

Also, as shown in FIG. 20, if the baffle 200 has a rotation shaft 210, by rotating the baffle 200 around the rotation shaft 210, it is possible to adjust the air flowing into the front air path and the The air flow of the air duct on the rear side is balanced. Therefore, the ratio of the air volume sent to the front outlet 3 and the rear outlet 4 can be adjusted freely.

As mentioned above, although each embodiment was demonstrated, each embodiment can also be combined suitably. In addition, the embodiment disclosed this time is an example in all respects and should be considered as non-limiting. The scope of the present invention is expressed not by the above description but by the scope of patent application, and is intended to include all meanings equivalent to the scope of patent application and all changes within the scope.
