FIG. 6 is a longitudinal sectional view showing an internal structure of the humidified air cleaner 1 shown in FIG. The cross section of the humidification air cleaner 1 seen from the side (left) from FIG. 6 is illustrated.

As shown in FIG. 6, a filter 41 is disposed in front of the rear panel 20. The filter 41 is an integrated dust collecting / deodorizing filter that collects fine dust and adsorbs odorous components in the air. Instead of the integral filter 41, the dust collection filter and the deodorizing filter may be separately configured and arranged so as to overlap each other.

The filter 41 is housed inside the housing 2 and is covered rearward by the rear panel 20. By removing the rear panel 20, the filter 41 can be easily accessed. Thus, maintenance work such as cleaning or replacement of the filter 41 is facilitated.

A hollow downdraft path 150 is formed in front of the filter 41, that is, inside the housing 2 rather than the filter 41.

The water storage tray 30 has a tray main body 31. The tray main body 31 has a container-like shape, and stores water inside thereof. A humidifying filter 32, an antibacterial agent 33, and a float 34 are disposed inside the tray main body 31.

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

The humidification filter 32 sucks up the water in the tray main body 31 by capillary action, and the whole becomes a state containing water. The upper non-flooded part of the humidification filter 32 is not immersed in water, but by absorbing water from the lower part, regardless of the amount of water stored in the tray main body 31, the moisture in the entire humidified filter 32 including the non-flooded part Go around.

The antibacterial agent 33 is immersed in the water stored in the tray main body 31. The antimicrobial agent 33 contains an antimicrobial component. By dissolving the antibacterial component in the water stored in the tray main body 31, the antibacterial function of suppressing the generation of bacteria or mold in the water in the tray main body 31 and the humidifying filter 32 is exhibited.

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

A blower 50 is disposed in the housing 2. The water storage tray 30 is disposed below the blower 50. The blower 50 is disposed in front of the filter 41 so as to be separated from the filter 41. The downward air passage 150 is formed between the blower 50 and the filter 41 in the front-rear direction.

The blower 50 has a fan 52 for blowing gas, a fan motor 53 as a motor for rotationally driving the fan 52, and a fan casing 54 for housing the fan 52 and the fan motor 53. The fan casing 54 has an opposing surface 56 facing the front panel 10. The opposing surface 56 is spaced apart from the front panel 10.

Between the front panel 10 and the facing surface 56 of the fan casing 54, a hollow upstream air passage 160, which is a passage through which the air flowing to the fan 52 flows, is formed. The upstream air passage 160 constitutes a part of the passage on the upstream side of the fan 52 in the passage through which 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 which is an air flow passage of the gas blown by the fan 52.

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

A downstream air passage 170, which is a passage through which the air flowing out of the fan 52 flows, is formed above the fan 52. The downstream air passage 170 constitutes a part of a passage downstream of the fan 52 in a passage through which the air blown by the fan 52 flows. In the branch portion 180, the air passage is branched into two, a front air path 183 connected to the front outlet 3 and a rear air path 184 connected to the rear outlet 4. The front outlet 3 is provided at the upper end of the front air passage 183. The rear outlet 4 is provided at the upper end of the rear air passage 184. The front outlet 3 and the rear outlet 4 are provided at the downstream end of the flow of air blown by the fan 52.

The high pressure generation unit 100 is disposed in the downstream air passage 170. The high pressure generation unit 100 protrudes from the wall surface of the downstream air passage 170 into the downstream air passage 170. The high voltage generation unit 100 generates active species such as ions by discharge. As a result, the air flowing through the high pressure generation unit 100 contains active species.

The air passing through the filter 41 and flowing into the inside of the housing 2 is blown to the water storage tray 30 provided below the humidified air cleaner 1 through the downward air passage 150. The air passes through the absorbed humidification filter 32 to humidify the air. Thereafter, the humidified air is blown to the blower 50. The rotation of the fan 52 allows air to flow. In the downstream air passage 170, the air contains active species. Then, air that is humidified and contains active species is released to the outside (indoor) from the front outlet 3 and the rear outlet 4.

FIG. 7 is a schematic view showing the flow of gas in the downstream air passage 170. As shown in FIG. FIG. 7 shows a partial configuration of the inside of the housing 2 of the humidified air purifier 1 seen through from behind. The right direction in the drawing is the right direction of the humidified air cleaner 1, and the left direction in the drawing is the left direction of the humidified air cleaner 1. Arrows in the drawing indicate the rotational directions of the fan 52 and the fan motor 53.

The fan casing 54 has air passage wall surfaces 172 and 174 that define the downstream air passage 170. The air passage wall surfaces 172 and 174 are inclined with respect to the vertical direction of the humidified air cleaner 1 so as to be directed rightward as it goes upward. Because the fan 52 rotates in the clockwise direction in FIG. 7, the air flowing from the fan 52 into the downstream air passage 170 flows more into the vicinity of the air passage wall 172 and the flow velocity of the air flowing in the vicinity of the air passage wall 172 is growing. By arranging the air passage wall surface 172 in an inclined manner with respect to the vertical direction, the imbalance of the flow rate and flow velocity of the air in the left and right direction in the downstream air passage 170 is reduced in the downstream air passage 170. The flow rate of air flowing through is increased.

FIG. 8 is a perspective view showing the configuration of the high pressure generation unit 100. As shown in FIG. The high voltage generation unit 100 includes a unit housing 101 and

The

discharge parts

102 and 103 have a plurality of linear conductors and a base for bundling the conductors. The linear form includes thread, fiber and wire. The conductor is formed of a conductive material.

discharge units

102 and 103 are brush-like electrodes whose longitudinal direction is the direction in which the discharge unit 102 protrudes from the unit housing 101.

The

discharge units

102 and 103 are applied with a voltage and discharged to generate active species such as ions, electrons, radicals, and ozone. The discharge unit 102 is, for example, a discharge electrode for generating positive ions. The discharge unit 103 is, for example, a discharge electrode for generating negative ions. The discharge unit 102 generates positive ions by applying and discharging a high voltage. The discharge unit 103 generates negative ions by applying and discharging a high voltage.

The positive ion is a cluster ion in which a plurality of water molecules are clustered around a hydrogen ion (H ⁺ ), and is expressed as H ⁺ (H ₂ O) _m (m is an arbitrary integer of 0 or more). The negative ion is a cluster ion in which a plurality of water molecules are clustered around an oxygen ion (O ₂ ⁻ ), and is expressed as O ₂ ⁻ (H ₂ O) _n (n is an arbitrary integer of 0 or more). When positive and negative ions are released into the room, both ions surround mold fungi and viruses suspended in the air and cause a chemical reaction on their surfaces. Floating molds and the like are removed by the action of hydroxyl radicals (.OH) of active species generated at that time.

[Correction based on rule 91 22.06.218]
In the state where the holder 110 is accommodated in the holder accommodating portion 130, the holder 110 reaches the deepest portion of the holder passage 131. In this state, the gripping portion 118 of the holder 110 exists outside the holder accommodating portion 130 as shown in FIG. The user can remove the holder 110 and the high-pressure generating unit 100 from the holder accommodating portion 130 by holding the gripping portion 118 with his / her finger and removing it from the opening 132.

A portion of the upper guide portion 112 of the holder 110 is disposed in the upper groove 133 of the holder accommodating portion 130. A portion of the lower guide portion 113 of the holder 110 is disposed in the lower groove 134 of the holder accommodating portion 130. The combination of the upper guide portion 112 and the upper groove 133 and the combination of the lower guide portion 113 and the lower groove 134 have a function of guiding the holder 110 when the holder 110 is attached to the holder accommodating portion 130. It has a positioning function to position the holder 110 attached to the portion 130 at an appropriate position.

As shown in FIG. 16, the high voltage generation unit 100 is electrically connected to the connector 140 attached to the holder housing portion 130. When attaching the holder 110 to the holder accommodating portion 130, the connector 140 passes through the connector accommodating portion 116 of the holder 110 and moves relative to the connecting portion 108 formed in the unit housing 101. Therefore, the connector 140 does not prevent the movement of the holder 110 and the high pressure generating unit 100.

The rib 139 protruding from the side wall surface 138 of the holder accommodating portion 130 shown in FIG. 14 moves relative to the inside of the rib accommodating portion 115 when the holder 110 is attached to the holder accommodating portion 130. Therefore, the rib 139 does not prevent the movement of the holder 110 and the high pressure generating unit 100.

A part of the bottom surface 111 </ b> A of the main body 111 of the holder 110 is placed on the opening bottom surface 136 of the holder housing 130. Of the bottom wall surface 135 of the holder passage 131, the opening bottom surface 136 in the vicinity of the opening 132 constitutes a sliding portion that slides relative to the bottom surface 111A of the holder 110 that moves relative to the holder housing 130 There is.

FIG. 19 is a perspective view from the rear of the state in which the holder 110 is accommodated in the holder accommodating portion 130 attached to the housing 2. Similar to FIG. 14, the holder accommodation portion 130 and the high pressure generation unit 100 viewed from the downstream air passage 170 are illustrated in FIG. 19. When the high voltage generation unit 100 is attached to the holder accommodating portion 130 in a state of being held by the holder 110, the electrode protection portion 104 passes above the hook shaped portion 191 and passes above the second hook shaped portion 196. Do. The hook shape portion 191 and the second hook shape portion 196 do not interfere with the electrode protection portion 104.

As a result, as shown in FIG. 19, the high pressure generation unit 100 can be appropriately disposed at a predetermined position of the deepest portion of the holder passage 131. The humidified air cleaner 1 can ensure predetermined performance by applying a high voltage to the

discharge parts

102 and 103 of the high pressure generation unit 100 appropriately assembled and discharging the same.

Next, the behavior when attempting to insert the high pressure generation unit 100 alone into the holder accommodating portion 130 without attaching the high pressure generation unit 100 to the holder 110 will be described.

When the holder 110 is broken, or when the holder 110 is lost, for example, the user may consider inserting the high pressure generation unit 100 into the holder accommodating portion 130 for use. In such a case, a gap is formed due to the absence of the holder 110, and a flow of air leaking via the gap is generated. As a result, unintended unbalance occurs in the air flow in the downstream air passage 170. An imbalance occurs in the flow of air that transports positive and negative ions generated in the

discharge units

102 and 103, and the air flows into the front air passage 183 and flows out from the front air outlet 3 to the outside of the device, and the air passage backward An imbalance occurs in the concentration of positive and negative ions in the air flowing into the air from the outlet 4 to the outside of the apparatus after flowing into the space 184.

As described above, in the humidified air cleaner 1, floating molds and viruses in the air are removed by the chemical reaction of positive ions and negative ions. Therefore, when the concentration imbalance between positive ions and negative ions contained in the air is large, the air cleaning ability to remove suspended mold and viruses etc. is not sufficiently exhibited. Thus, the performance of the humidified air cleaner 1 may be degraded.

Furthermore, the unintended noise may be generated by the flow of air passing through the above-mentioned gap, which may make the user uncomfortable or may not be able to comply with the regulation value related to the noise generated by the humidified air cleaner 1. is there.

The humidified air cleaner 1 according to the present embodiment is for solving such an event. FIG. 20 is a side view of a state in which the high pressure generating unit 100 alone is to be inserted into the holder passage 131. As shown in FIG. As shown in FIG. 20, the high pressure generating unit 100 not attached to the holder 110 moves along the opening bottom surface 136. The lower surface of the high pressure generating unit 100 slides against the bottom surface 136 of the opening.

Referring to FIGS. 9, 10 and 18 together, the lower surface of the high pressure generating unit 100 attached to the holder 110 is located at a distance from the bottom surface 111A of the main body 111 of the holder 110 and disposed above the bottom surface 111A. It is done. When attaching the holder 110 to the holder accommodating portion 130, the bottom surface 111A of the holder 110 slides relative to the opening bottom surface 136. Therefore, when attempting to insert the high pressure generation unit 100 alone into the holder passage 131, the high pressure generation unit 100 is lower than the normal path through which the high pressure generation unit 100 attached to the holder 110 passes. I will go through the route.

Further, rattling of the high-pressure generating unit 100 occurs in the thickness direction (the left-right direction in FIG. 20) of the side wall surface 138 of the holder housing portion 130 by the thickness of the bottom surface of the unit housing portion 114 of the holder 110. Since the upper guide portion 112 and the lower guide portion 113 of the holder 110 do not exist, the movement of the high pressure generating unit 100 is not guided by the upper groove 133 and the lower groove 134 of the holder accommodating portion 130. The high pressure generating unit 100 alone has a play with respect to the holder passage 131.

FIG. 21 is a rear perspective view of a state in which the high pressure generating unit 100 alone is to be inserted into the holder passage 131. In FIG. 21, similarly to FIG. 19, the high pressure generation unit 100 viewed from the downstream air passage 170 is illustrated.

As described above, when the high pressure generation unit 100 reaches the hook shaped portion 191 as shown in FIG. 21 by the high pressure generation unit 100 passing through the lower path, the support 105D of the electrode protection portion 104 is the hook shaped portion 191. Collide with the tip 192 of the By giving a sense of incongruity to the user due to the collision, it is possible to make the user notice that the high pressure generation unit 100 alone is not properly attached to the holder housing portion 130.

FIG. 22 is a partial cross-sectional view of a state in which the high pressure generating unit 100 alone is to be advanced further than the hook shaped portion 191. As shown in FIG. FIG. 23 is a perspective view from the rear of a state in which the high pressure generating unit 100 alone is to be advanced further than the hook shaped portion 191.

As shown in FIG. 22, the bottom wall surface 135 of the holder passage 131 is on the back side of the holder passage 131 with respect to the opening bottom surface 136, that is, at a position farther from the opening 132 than the opening bottom surface 136. And a step portion 137 which falls downward. The hook shaped portion 191 is disposed further to the holder passage 131 than the step portion 137.

As shown in FIG. 22, when the user shifts the position of the high pressure generation unit 100 upward or the like to eliminate the collision between the support column 105D and the tip 192 of the hook shaped portion 191 and further advance the high pressure generation unit 100, as shown in FIG. When the high pressure generation unit 100 reaches the step portion 137, the high pressure generation unit 100 is inclined so that the back side of the holder passage 131 falls.

This inclination lowers the position of the electrode protection unit 104. As a result, as shown in FIG. 23, the support 105C of the electrode protection unit 104 collides with the hook shaped portion 191.

The holder accommodating portion 130 of the high-pressure generating unit 100 alone is given a sense of incongruity by the user due to the sudden displacement and impact when the high-pressure generating unit 100 falls at the step portion 137 and the collision of the support 105C against the hook shaped portion 191. The user can be made aware that the mounting is not appropriate.

FIG. 24 is a partial cross-sectional view of a state in which the high pressure generating unit 100 alone has reached the second hook shaped portion 196. As shown in FIG. 25 and 26 are perspective views from the rear of the state in which the high pressure generating unit 100 alone has reached the second hook shaped portion 196. FIG.

When the user shifts the position of the high pressure generation unit 100 upward or the like to eliminate the collision between the support column 105C and the hook shaped portion 191 and further advance the high pressure generation unit 100, as shown in FIG. When the whole of 100 passes through the step portion 137, the high pressure generation unit 100 passes through the lower path. Therefore, as shown in FIG. 25, when the high pressure generating unit 100 alone reaches the second hook shaped portion 196, the support 105B of the electrode protection portion 104 is hooked on the hooking portion 193 of the hook shaped portion 191. Alternatively, as shown in FIG. 26, the support 105D of the electrode protection unit 104 collides with the tip end 197 of the second hook shaped portion 196.

By giving a sense of incongruity to the user due to the hooking and the collision, it is possible to make the user notice that the high pressure generation unit 100 alone is not properly attached to the holder housing portion 130.

In order to eliminate the hooking of the support 105C to the hook shaped portion 191 shown in FIG. 25, it is necessary to once retract the high pressure generating unit 100 (move it to the opening 132 side). Therefore, the length in the extension direction of the beam portion 105A of the electrode protection portion 104 of the embodiment is set smaller than the distance between the tip end 192 of the hook shaped portion 191 and the tip end 197 of the second hook shaped portion 196 There is. Therefore, after the user moves the high pressure generation unit 100 upward to eliminate the collision between the support 105D and the second hook shape portion 196, the support 105D is placed on the second hook shape portion 196 and the hook shape portion 191 is obtained. When the high pressure generating unit 100 is retracted to remove the hooking, the pillars 105D drop from the second hooking portion 196 before the hooking portion 191 is released.

As described above, it is difficult for the high pressure generating unit 100 to move to the back side of the holder passage 131 by getting over both the hook shaped portion 191 and the second hook shaped portion 196, thereby giving a sense of discomfort to the user. The user can be made aware that the mounting of the holder 100 on the single unit holder 100 is not appropriate.

FIG. 27 is a perspective view from the rear of the state in which the high pressure generation unit 100 alone has reached the rib 139. FIG. When the user somehow cancels the interference between the electrode protection portion 104 and the hook shaped portion 191 and the second hook shaped portion 196 to further push the high voltage generating unit 100 forward, as shown in FIG. When reaching the rib 139 projecting from the side wall surface 138 of the portion 130, the unit housing 101 collides with the rib 139.

By giving a sense of incongruity to the user due to the collision, it is possible to make the user notice that the high pressure generation unit 100 alone is not properly attached to the holder housing portion 130.

As described above, the humidified air cleaner 1 of the present embodiment has a plurality of structures that can interfere with the high pressure generation unit 100 when the high pressure generation unit 100 is to be inserted alone into the holder housing portion 130.
