FIG. 15 is a perspective view showing a state before the holder 110 is stored in the holder accommodating portion 130. In FIG. 15, a state in which a part of the left front corner portion of the case 2 is cut out is shown so that the holder accommodating portion 130 installed inside the case 2 can be viewed. As described above, the user can grasp the holding portion 118 of the holder 110 with his fingers and insert the holder 110 from the opening portion 132 into the holder passage 131, so that the holder 110 can be attached to the holder accommodating portion 130 and high-voltage generation can be performed. Unit 100.

As shown in FIG. 15, the extending direction of the holder path 131, that is, the direction in which the holder 110 and the high-pressure generating unit 100 are inserted into the holder accommodating portion 130 is not consistent with the left-right direction of the humidifying air cleaner 1. The direction in which the holder 110 and the high-pressure generating unit 100 are inserted into the holder accommodating portion 130 is directed toward the front as the holder 110 and the high-pressure generating unit 100 are inserted into the holder accommodating portion 130, relative to the humidifying air cleaner 1 Tilt left and right. Among the discharge sections 102 and 103, the discharge section 103 is inserted deeper into the case 2 from the opening 132 of the holder accommodating section 130.

Therefore, in a state in which the holder 110 and the high-voltage generating unit 100 are housed in the case 2, the discharge section 102 is disposed closer to the rear than the discharge section 103, and the discharge section 103 is disposed closer to the front than the discharge section 102. Since the cover 26 is provided on the left side 2D of the case 2, the discharge unit 102 is arranged closer to the left than the discharge unit 103 in a state where the holder 110 and the high-voltage generating unit 100 are housed in the case 2. The discharge section 103 is disposed closer to the right than the discharge section 102.

16 and 17 are perspective views showing a state where the holder 110 has been stored in the holder accommodating portion 130. FIG. 18 is a side view showing a state where the holder 110 has been stored in the holder accommodating portion 130.

In a state where the holder 110 is stored in the holder accommodating portion 130, the holder 110 reaches the innermost part of the holder passage 131. In this state, as shown in FIG. 17, the holding portion 118 of the holder 110 exists outside the holder accommodating portion 130. The user can take out the holder 110 and the high-voltage generating unit 100 from the holder accommodating portion 130 by grasping the holding portion 118 with his fingers and pulling out the opening portion 132.

A part of the upper guide portion 112 of the holder 110 is disposed in the upper groove 133 of the holder accommodating portion 130. A part 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 the function of guiding the holder 110 when the holder 110 is mounted on the holder accommodating portion 130, and have a suitable function. The positioning function of the holder 110 which has been installed in the holder accommodating portion 130 is provided.

As shown in FIG. 16, the high-voltage generating unit 100 is electrically connected to the connector 140 that has been mounted on the holder accommodating portion 130. When the holder 110 is attached to the holder accommodating portion 130, the connector 140 moves relative to the connection portion 108 formed in the unit case 101 through the connector accommodating portion 116 of the holder 110. Therefore, the connector 140 does not hinder the movement of the holder 110 and the high-voltage generating unit 100.

The rib 139 protruding from the side wall surface 138 of the holder accommodating portion 130 shown in FIG. 14 is relatively moved in the rib accommodating portion 115 when the holder 110 is mounted on the holder accommodating portion 130. Therefore, there is no case where the rib 139 hinders the movement of the holder 110 and the high-pressure generating unit 100.

A part of the bottom surface 111A of the main body portion 111 of the holder 110 is placed on the opening bottom surface 136 of the holder accommodating portion 130. Among the bottom wall surfaces 135 of the holder passage 131, the opening bottom surface 136 in the vicinity of the opening portion 132 constitutes a sliding portion that slides with respect to the bottom surface 111A of the holder 110 that is relatively moved with respect to the holder accommodating portion 130.

FIG. 19 is a perspective view seen from the rear in a state where the holder 110 is accommodated in the holder accommodating portion 130 mounted on the case 2. In FIG. 19, similarly to FIG. 14, the holder accommodating portion 130 and the high-pressure generating unit 100 viewed from the downstream air path 170 are illustrated. When the high-voltage generating unit 100 is mounted on the holder accommodating portion 130 while being held by the holder 110, the electrode protection portion 104 passes above the hook-shaped portion 191 and also above the second hook-shaped portion 196. There is no case where the hook-shaped portion 191 and the second hook-shaped portion 196 interfere with the electrode protection portion 104.

Accordingly, as shown in FIG. 19, the high-pressure generating unit 100 can be appropriately arranged at a predetermined position in the innermost part of the holder passage 131. By applying a high voltage to the discharge sections 102 and 103 of the high-voltage generating unit 100 that has been appropriately installed to discharge the high-voltage generating unit 100, the humidifying air cleaner 1 can ensure a predetermined performance.

Next, an operation when the high-voltage generating unit 100 is to be inserted into the holder accommodating portion 130 without separately mounting the high-voltage generating unit 100 on the holder 110 will be described.

Considering that the holder 110 is broken, the holder 110 is lost, etc., the user wants to insert the high-voltage generating unit 100 into the holder accommodating portion 130 and use it separately. In such a case, a gap is formed by the absence of the holder 110, and a flow of air leaking through the gap is generated. This causes an unintended imbalance in the air flow in the downstream air path 170. Due to the imbalance in the flow of air that transports the positive and negative ions generated by the discharge units 102 and 103, the air flowing into the forward air path 183 and flowing out from the front air outlet 3 to the outside of the device, and into the rear air path 184 and from The concentration of positive and negative ions in the air flowing out of the rear blowing port 4 to the outside of the device is uneven.

As described above, in the humidifying air cleaner 1, the planktonic molds, viruses, and the like in the air are removed by a chemical reaction between positive and negative ions. Therefore, when the concentration of positive and negative ions contained in the air is imbalanced, the air-cleaning ability to remove airborne molds and viruses cannot be fully exhibited. As a result, there is a possibility that the performance of the humidifying air cleaner 1 may decrease.

Furthermore, unintentional noise is generated due to the flow of air passing through the gap, thereby giving a user unpleasant feeling, and there is a possibility that the predetermined value of the noise generated by the humidifying air cleaner 1 cannot be observed.

The humidifying air cleaner 1 according to this embodiment is used to solve such a situation. FIG. 20 is a side view showing a state in which the high-voltage generating unit 100 is inserted into the holder passage 131 alone. As shown in FIG. 20, the high-voltage generating unit 100 that is not attached to the holder 110 moves along the opening bottom surface 136. The lower surface of the high-pressure generating unit 100 slides with respect to the opening bottom surface 136.

Referring to FIGS. 9, 10 and 18 together, the lower surface of the high-voltage generating unit 100 that has been mounted on the holder 110 is located at a position separated from the bottom surface 111A of the main body portion 111 of the holder 110, and is disposed above the bottom surface 111A. When the holder 110 is attached to the holder accommodating portion 130, the bottom surface 111A of the holder 110 slides with respect to the opening bottom surface 136. Therefore, when the high-voltage generating unit 100 is to be individually inserted into the holder passage 131, the high-voltage generating unit 100 passes the regular path closer to the lower path than the normal path through which the high-voltage generating unit 100 is mounted in the holder 110.

In addition, the thickness of the bottom surface of the unit accommodation portion 114 of the holder 110 causes the high-pressure generating unit 100 to loosen in the thickness direction (left-right direction in FIG. 20) of the side wall surface 138 of the holder accommodation portion 130. Since the upper guide portion 112 and the lower guide portion 113 of the holder 110 do not exist, the upper groove 133 and the lower groove 134 of the holder accommodating portion 130 do not guide the movement of the high-pressure generating unit 100. The high-voltage generating unit 100 has a backlash with respect to the holder path as a single body.

FIG. 21 is a perspective view of the state where the high-voltage generating unit 100 is inserted into the holder passage 131 as viewed from the rear. 21 and FIG. 19, the high-pressure generating unit 100 viewed from the downstream air path 170 is illustrated.

When the high-voltage generating unit 100 passes the lower path as described above, as shown in FIG. 21, when the high-voltage generating unit 100 reaches the hook-shaped portion 191, the pillar 105D of the electrode protection portion 104 collides with the front end 192 of the hook-shaped portion 191. This collision gives a sense of discomfort to the user, so that the user can perceive that the installation of the high-voltage generating unit 100 alone into the holder accommodating portion 130 is not appropriate.

FIG. 22 is a partial cross-sectional view of a state where the high-voltage generating unit 100 is intended to be advanced inside more than the hook-shaped portion 191. FIG. 23 is a perspective view of the high-pressure generating unit 100 as viewed from the rear, in a state where the high-voltage generating unit 100 is advanced inside than the hook-shaped 191 portion.

As shown in FIG. 22, the bottom wall surface 135 of the holder passage 131 is closer to the inside of the holder passage 131 than the opening bottom surface 136, that is, at a position farther from the opening portion 132 than the opening bottom surface portion 136. 136 The level difference portion 137 which sinks downward. The hook-shaped portion 191 is disposed on the inner side of the stepped portion 137 near the holder passage 131.

In the case where the user moves the position of the high-voltage generating unit 100 upwards, etc., and the collision between the pillar 105D and the front end 192 of the hook-shaped portion 191 is released, and the high-voltage generating unit 100 is further pushed forward, as shown in FIG. 22, When the high-pressure generating unit 100 reaches the level difference portion 137, the inside of the holder passage 131 is sunken, and the high-pressure generating unit 100 is inclined.

With this inclination, the position of the electrode protection portion 104 is lowered. As a result, as shown in FIG. 23, the pillar 105C of the electrode protection portion 104 collides with the hook-shaped portion 191.

The severe displacement and impact of the high-pressure generating unit 100 when the level difference portion 137 subsides, and the collision of the pillar 105C with the hook-shaped portion 191 give the user a sense of disagreement, so that the user can perceive the high-voltage generating unit. The installation of 100 units to the holder accommodating portion 130 is not appropriate.

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

In the case where the user moves the position of the high-voltage generating unit 100 upward, etc., and cancels the collision between the pillar 105C and the hook-shaped portion 191, and pushes the high-voltage generating unit 100 further forward, as shown in FIG. The whole of the unit 100 passes through the level difference portion 137, so that the high-voltage generating unit 100 further passes the path below. Therefore, as shown in FIG. 25, when the high-voltage generating unit 100 alone reaches the second hook-shaped portion 196, the pillar 105B of the electrode protection portion 104 is hooked to the hook portion 193 of the hook-shaped portion 191. Alternatively, as shown in FIG. 26, the pillar 105D of the electrode protection portion 104 collides with the front end 197 of the second hook-shaped portion 196.

Due to the hang and collision, the user is given a sense of disagreement, so that the user can perceive that the installation of the high-voltage generating unit 100 into the holder accommodating portion 130 is not appropriate.

To release the hook 105C from hooking to the hook-shaped portion 191 shown in FIG. 25, it is necessary to temporarily retract the high-voltage generating unit 100 (to move toward the opening 132 side). Therefore, the length in the extending direction of the beam portion 105A of the electrode protection portion 104 according to the embodiment is set to be smaller than the distance between the front end 192 of the hook-shaped portion 191 and the front end 197 of the second hook-shaped portion 196. Therefore, on the premise that the user moves the high-voltage generating unit 100 upward to release the collision between the pillar 105D and the second hook-shaped portion 196, when the pillar 105D is carried on the second hook-shaped portion 196, the user wants to separate the hook 105D. When the high-voltage generating unit 100 is retracted by the hooking of the shape portion 191, the pillar 105D falls from the second hook-shaped portion 196 before the hooking to the hook-shaped portion 191 is released.

In this way, it becomes difficult for the high-pressure generating unit 100 to pass through both the hook-shaped portion 191 and the second hook-shaped portion 196 toward the inside of the holder passage 131. By giving a sense of discomfort to the user, the user can perceive that The installation of the high-voltage generating unit 100 into the holder accommodating portion 130 is not appropriate.

FIG. 27 is a perspective view of the high-pressure generating unit 100 as viewed from the rear in a state where the high-pressure generating unit 100 alone has reached the rib 139. In a case where the user releases the interference of the electrode protection portion 104 with the hook-shaped portion 191 and the second hook-shaped portion 196 in some way and pushes the high-voltage generating unit 100 further forward, as shown in FIG. 27, in the high-voltage generating unit, When 100 reaches the rib 139 protruding from the side wall surface 138 of the holder accommodating portion 130, the unit case 101 collides with the rib 139.

This collision gives a sense of discomfort to the user, so that the user can perceive that the installation of the high-voltage generating unit 100 alone into the holder accommodating portion 130 is not appropriate.

As described above, the humidifying air cleaner 1 according to the present embodiment is provided with a plurality of structures that can interfere with the high-pressure generating unit 100 when the high-pressure generating unit 100 is to be individually inserted into the holder accommodating portion 130. By allowing the user to repeatedly feel many senses of disagreement, the user can be more surely aware that the installation of the high-voltage generating unit 100 to the holder accommodating portion 130 is not appropriate.

(Second Embodiment) FIG. 28 is a perspective view from the rear of a state where a high-pressure generating unit 100 according to a second embodiment is to be inserted into a holder passage 131 alone. FIG. 29 is a perspective view of the high-voltage generating unit 100 according to the second embodiment, as viewed from the rear, in a state where a single unit of the high-voltage generating unit 100 has been inserted into the cutout portions 292, 294, and 296.

In the first embodiment, an example in which two hook-shaped portions (hook-shaped portion 191 and second hook-shaped portion 196) are provided has been described, but it is not limited to this example. For example, as shown in FIGS. 28 and 29, It is also possible to have a configuration in which three hook-shaped portions 291, 293, and 295 are provided, and three cutout portions 292, 294, and 296 corresponding to these hook-shaped portions 291, 293, and 295 are formed.

The interval between the hook-shaped portions 291 and 293 is equal to the interval between the pillars 105B and 105C of the electrode protection unit 104, and the interval between the hook-shaped portions 293 and 295 is equal to the interval between the pillars 105C and 105D of the electrode protection unit 104. When each of the pillars 105B, 105C, and 105D reaches the cutout portions 292, 294, and 296, the entire electrode protection portion 104 is sunk into the cutout portions 292, 294, and 296, and is further inserted into the hook when it is pushed further inward. The key shapes of the shape parts 291, 293, and 295.

When the high-voltage generating unit 100 sinks into the notches 292, 294, and 296, an impact is applied. Furthermore, in order to pull the high-voltage generating unit 100 from the notches 292, 294, and 296, it is necessary to temporarily move the high-voltage generating unit 100 upward and downward. mobile. Due to these unnatural movements, a sense of discomfort is given to the user, so that the user can perceive that the installation of the high-voltage generating unit 100 alone into the holder accommodating portion 130 is not appropriate.

(Embodiment 3) FIG. 30 is a partial cross-sectional view of a state where a high-pressure generation unit 100 according to Embodiment 3 is to be inserted into a holder passage 131. FIG. 31 is a perspective view of the state where the high-voltage generating unit 100 according to the third embodiment is to be inserted into the holder passage 131 as viewed from the rear. In addition to the configuration of the first embodiment, the humidifying air cleaner 1 according to the third embodiment further includes a notch-shaped portion 199 in which a top portion 189 formed in the opening 188 of the fan case 54 is cut out. The notch-shaped portion 199 is provided closer to the inner side of the holder passage 131 than the hook-shaped portion 191 (the side away from the opening portion 132), and closer to the front side of the holder passage 131 (the side closer to the opening portion 132) than the second hook-shaped portion 196. .

As shown in FIGS. 30 and 31, when the high-voltage generating unit 100 is pushed upward inside the holder passage 131 so that the hook-shaped portion 191 does not interfere with the electrode protection portion 104, the unit case 101 or the electrode The pillar 107D of the protection portion 106 is fitted into the notch-shaped portion 199 and cannot be directly pushed inward. When the high-voltage generating unit 100 is moved downward to avoid interference with the notch-shaped portion 199, the electrode protection portion 104 collides with the hook-shaped portion 191, for example, hooking of the pillar 105C to the hanging portion 193 occurs.

In this way, a sense of disobedience is given to the user, so that the user can perceive that the installation of the high-voltage generating unit 100 alone into the holder accommodating portion 130 is not appropriate.

In the description of the embodiments so far, the configuration has been described in which the hook-shaped portion 191 and the second hook-shaped portion 196 are formed in the fan case 54, and the level difference portion is formed in the holder accommodating portion 130. 137, a rib 139 protrudes from a side wall surface 138 of the holder accommodating portion 130.
