FIG. 4 is an exploded perspective view showing the humidifying device according to Embodiment 1 of the present invention. As shown in FIG. 4 , a front panel 41 and a pre-filter 42 are provided on the upstream side of the humidification filter 12 .

A pre-filter 42 is provided on the front panel 41 and serves to prevent dust from entering the main body.

The front panel 41 is provided with elastic hooks 43 on the lower side surface.

The front panel 41 forms a part of the body case 1 by being attached to the corresponding portion of the body case 1 via the hooks 43 .

The feature of this embodiment is that the front panel 41, the pre-filter 42, the humidifying filter 12, the drain pan 16, and the water storage container 11 are configured to be removable from the front surface of the main body case 1, as shown in FIG. .

As described above, the water storage container 11 is provided with the tank portion 31 and the pump 17 . In general humidifiers, scales and impurities contained in tap water adhere to water channels. Also, dust contained in the air is collected by the pre-filter, and fine dust that has passed through the pre-filter 42 adheres to the humidification filter 12 . That is, the pre-filter 42, the humidifying filter 12, the drain pan section 16, the pump 17, the tank section 31, and the water storage container 11 need regular maintenance.

Since these components are detachable from the front surface of the main body case 1, maintenance can be easily performed without moving the main body. That is, it improves usability for the user.

The shape of the front panel 41 will be described in detail with reference to FIGS. 5 and 6. FIG.

FIG. 5 is a perspective view of the front panel 41 viewed obliquely from the front right.

FIG. 6 is an exploded perspective view of the front panel 41 viewed obliquely from the rear right.

When viewed from the front, the front panel 41 has an uneven shape composed of a plurality of windward surfaces 44 and leeward surfaces 45 . The windward surface 44 and the leeward surface 45 are spaced apart from each other by a constant distance, and the end surfaces thereof are formed by connecting surfaces 46 or slits 47 . The presence of the joint surface 46 ensures strength and makes the appearance beautiful. Air is taken into the main body from the slit 47 (suction port 7).

As shown in FIGS. 5 and 6, the connecting surface 46 may be provided on the same side (for example, the right side of the windward surface 44). By doing so, the appearance is good, and sufficient strength can be ensured. When the front panel 41 is viewed from an angle as shown in FIG. 5, the slit 47 is a blind spot.

The pre-filter 42 is composed of a pre-filter frame 48 and a purification filter 49 .

The pre-filter frame 48 is made of resin or the like, and is provided with claws 50 for attachment to the front panel 41 and pre-filter ribs 51 extending in the leeward direction.

The purification filter 49 is made by processing resin or the like into fibers. The purification filter 49 is fixed to the pre-filter frame 48 by welding to the pre-filter frame 48 or the like.

The claws 50 are plate-shaped ribs extending in the vertical direction, and are provided in plurality at the upper and lower ends of the pre-filter frame 48 . The front panel 41 is provided with horizontally long grooves (not shown), and is fixed to the front panel 41 by inserting the upper and lower claws 50 .

As shown in FIG. 6, the pre-filter 42 may consist of two or more. As a result, since the size of each sheet is reduced, handling becomes easier when removing for maintenance. As a result, usability for the user is improved.

The pre-filter rib 51 is a rib extending horizontally near the center of the pre-filter 42, as shown in FIG. When the front panel 41 is assembled in the main body case 1 , the pre-filter rib 51 contacts the humidifying filter 12 on the leeward side of the pre-filter 42 to suppress bending of the pre-filter 42 . When the pre-filter 42 is removed from the front panel 41 for maintenance or the like, the pre-filter rib 51 serves as a knob, which facilitates removal.

The operation of the hook 43 will be described. As shown in FIG. 7, the upper end of the front panel 41 is attached to the upper end of the main body case 1 so as to be hooked thereon. 41 can be fixed. When removing the front panel 41, the hook 43 is pressed to release the hook 43 from the body case 1, and then pulled up in the direction of the arrow in FIG.

Here, the shape of the hook 43 will be described with reference to FIG. The hook 43 is composed of a hook spring 52 having elasticity, a hook presser 53 operated by the user, and a hook claw 54 hooked on the body case 1.例文帳に追加The hook spring 52 is incorporated inside the front panel 41, and the hook retainer 53 is configured to be exposed to the outer shell. When the user presses the hook retainer 53, the hook spring 52 bends and the hook claw 54 moves inward (in the direction of the arrow), so that the main body case 1 is released and can be pulled out. Further, such an attachment/detachment mechanism using the hook 43 can also be applied to the water storage container 11 .

With such a configuration, the height of the upper end of the front panel 41 and the height of the top surface of the main body case 1 are easily matched, and the external appearance is improved. In addition, since both ends of the front panel 41 can be held with both hands while the hooks 43 are pressed and pulled up, the usability of the user when removing the front panel 41 is improved.

(Embodiment 2)
The shape of the humidifying filter 12 will be described in detail.

FIG. 9 is a perspective view of the humidifying filter 12 as seen from the windward side.

FIG. 10 is a perspective view of the humidifying filter 12 as seen from downwind.

As shown in FIGS. 9 and 10, the humidifying filter 12 is composed of a filter frame 61 made of resin or the like and a fibrous filter portion 62 having water absorption properties.

As shown in FIG. 10, the upper portion of the filter frame 61 has an inlet portion 63 for supplying water. Although the inflow portion 63 is provided on the leeward side of the filter frame 61 in this embodiment, it may be provided at the upper end portion of the filter frame 61 instead of being provided on the leeward side of the filter frame 61 .

FIG. 11 is a partial cross-sectional view of the II-II cross section of FIG. 9 viewed in the direction of the arrow. As shown in FIG. 11 , the filter unit 62 is composed of a plurality of filters 64 in the direction of the air passage 10 , and water is supplied to the filter 64 on the windward side as indicated by a water passage 65 .

The air passing through the filter part 62 gradually increases its humidity while depriving the filter part 62 of moisture. That is, the air passing through the filter section 62 has the lowest humidity when it passes through the first layer of the filter 64, which is the most upwind, and passes through the filter 64, which is the most downwind (fourth layer in the case of FIG. 11). Humidity is highest when That is, by supplying water to the filter 64 on the windward side, water can be supplied so as to compensate for the large amount of evaporation, so that the most efficient humidification can be achieved. On the other hand, the filter 64 on the leeward side is sufficiently flooded by the action of the blowing air. As a result, a wide area of the filter portion 62 can be flooded evenly, and humidification performance can be improved.

In addition, by configuring the filter portion 62 with a plurality of layers of filters 64, one filter 64 can be made thinner, which facilitates maintenance. In particular, since the filter 64 on the windward side absorbs and desorbs a large amount of moisture, impurities contained in tap water and fine dust in the room tend to accumulate. By configuring the filter section 62 with a plurality of filters 64, only the filter 64 on the windward side can be cleaned or replaced as necessary. As a result, the life of the filter part 62 can be improved.

Note that the plurality of filters 64 in FIG. 11 can use independent filters for each layer.

Alternatively, the filter 64 may be sewn into a tubular shape, as shown in FIG. In FIG. 12, a four-layer structure is formed by using, for example, two cylindrical filters 64 instead of independent filters for each layer. FIG. 12 shows a state in which the filter part 62 is removed from the filter frame 61 and viewed from the windward side (left side in FIG. 11). Since the tubular filter 64 has elasticity, it has the property of expanding into an elliptical shape as shown in FIG. 12 when removed from the filter frame 61 . Since the filter 64 is actually attached to the filter frame 61, each layer continues without gaps like the filter 64 in FIG.

The filter 64 of FIG. 12 employs a knitting method that facilitates water infiltration in the horizontal direction X. As shown in FIG. By sewing the filter 64 into a cylindrical shape, the water supplied to the first layer easily permeates in the lateral direction X, and the second layer is also easily permeated. Moreover, the water supplied to the third layer is easily flooded to the fourth layer by using the property that the water is easily flooded in the horizontal direction X. As a result, humidification performance can be improved. Although two cylindrical filters 64 are used, one or more may be used.

FIG. 13 is an exploded perspective view of the filter frame 61. FIG. The filter frame 61 is composed of a windward filter frame 66 and a leeward filter frame 67 . By adopting such a configuration, the filter portion 62 can be easily removed from the filter frame 61, which facilitates maintenance. Further, the windward filter frame 66 and the leeward filter frame 67 are provided with pins 68 extending toward the filter portion 62 at regular intervals. That is, the pins 68 of the windward filter frame 66 extend in the leeward direction, and the pins 68 of the leeward filter frame 67 extend in the windward direction. Since the pin 68 is configured to be inserted into the filter portion 62, the filter portion 62 can be held at a regular position without shifting due to its own weight.

Also, the windward filter frame 66 is shallower than the leeward filter frame 67 . That is, the thickness of the windward filter frame 66 is smaller than the thickness of the leeward filter frame 67 in the direction of air flow.

As mentioned above, the windward filter 64 is easily soiled, and similarly, the windward filter frame 66 is also easily soiled. That is, by making the leeward filter frame 67, which is hard to get dirty, deep and the windward filter frame 66, shallow, the windward filter frame 66 which is easy to get dirty is easy to handle, resulting in easy maintenance.

Further, as shown in FIG. 10, the filter frame 61 is provided with attachment/detachment detection means 69 . This stops the operation of the air blower 3 and the pump motor 18 when the humidifying filter 12 is not attached to the main body case 1 . This can be expected to have the effect of preventing water leakage by stopping the operation of the main body when the humidifying filter 12 that has been removed for maintenance or the like is forgotten to be installed or is not assembled correctly. An example of the attachment/detachment detection means 69 is composed of a magnet incorporated in the filter frame 61 and a sensor incorporated in the main body case 1 that can detect the magnet, and detects when the magnet and the sensor are separated from each other by a predetermined distance or more. configuration, etc.

As shown in FIG. 14, the humidifying filter 12 has a structure in which the lower end is housed in the drain pan portion 16 (FIG. 4) and the upper portion is stopped by a movable stopper 70. As shown in FIG. The humidifying filter 12 can be switched between a fixed state and a released state by the stopper 70 .

As shown in FIG. 10, the attachment/detachment detection means 69 is preferably provided on the top or upper end of the filter frame 61 . With such a configuration, when the humidifying filter 12 is not assembled correctly, the upper end of the humidifying filter 12 is farthest away from the main body case 1, so attachment/detachment can be easily detected.

The attachment/detachment detection means 69 is preferably provided on the upper portion or the upper end portion of the leeward filter frame 67 . Since the leeward filter frame 67 has a greater thickness than the windward filter frame 66, it becomes easier to secure a space for providing the attachment/detachment detection means 69. - 特許庁

The lower part of the leeward filter frame 67 is provided with a draining portion 71 as shown in FIG. This serves as an opening for collecting surplus water in the filter section 62 and flowing it out to the drain pan section 16 .

Further, the windward filter frame 66 and the leeward filter frame 67 are provided with a filter grid 72 to hold the filter portion 62 so as not to fall off. By making the shape of the filter grid 72 of the windward filter frame 66 and the shape of the filter grid 72 of the leeward filter frame 67 the same, the pressure loss is minimized. As a result, improvement in humidification performance can be expected.

As shown in FIG. 11, the filter grid 72 has a U-shaped cross-section that opens outward and has protrusions on the inside. With such a shape, even if water droplets drip on the surface of the filter portion 62 , the water is less likely to leak outside the filter frame 61 , and the water droplets can be collected by the filter portion 62 or the water drain portion 71 . Become.

FIG. 15 is a partial cross-sectional view of the III-III cross section of FIG. 14 as viewed in the direction of the arrow.

The supply section 15 is composed of a first supply section 81 and a second supply section 82 . The water pumped up from the pump 17 is distributed to the first supply section 81 and the second supply section 82, and supplied to the humidification filter 12, respectively. As a result, water can be efficiently supplied to the humidification filter 12, and thus an improvement in humidification performance can be expected.

As shown in FIG. 14, the humidification filter 12 may be configured by a first humidification filter 12A and a second humidification filter 12B, and water may be supplied to each of them. Water is supplied from a first supply unit 81 to the first humidification filter 12A, and water is supplied from a second supply unit 82 to the second humidification filter 12B. By configuring the humidification filter 12 with a plurality of sheets, the water retention amount of the humidification filter 12 is increased, the humidification performance is improved, and the size of each humidification filter 12 is reduced, so that the maintainability is improved. Effective.

In the present embodiment, a first supply portion 81 is provided in the middle of a water channel, and in the first supply portion 81, a water channel leading to the humidification filter 12 and a third pipe 83 (connection hose). At this time, the first supply part 81 and the second supply part 82 are preferably at the same height. This makes it possible to distribute the supplied water evenly without being biased to either side.

In this embodiment, the third tube 83 uses a flexible material (for example, silicon). The third pipe 83 between the first supply part 81 and the second supply part 82 is preferably made to protrude downward by using the weight of the third pipe 83 itself. That is, the lower end of the third pipe 83 is arranged below the first supply section 81 and the second supply section 82 . Thereby, the lower end of the third pipe 83 is arranged at a lower position than the first supply portion 81 . That is, in the first supply part 81, the water supplied from the second pipe 20 can also flow into the third pipe 83 by its own weight. As a result, it becomes possible to more uniformly distribute water to the first supply section 81 and the second supply section 82 .

The first supply section 81 has a first communicating tube section (hidden by the second tube 20 and the third tube 83 in FIG. 15 and cannot be seen) and a first opening 81A.

The second supply part 82 has a second communicating pipe part (hidden by the third pipe 83 in FIG. 15 and not visible) and a second opening 82A.

The first communicating pipe portion and the second communicating pipe portion communicate with each other through the third pipe 83, and the bottom surface of the highest inner surface of the first communicating pipe portion and the bottom surface of the highest inner surface of the second communicating pipe portion are the same. height, and the bottom surface of the lowest inner surface of the third tube 83 is arranged below the highest bottom surface of the first communicating tube portion and the highest bottom surface of the second communicating tube portion. The first opening 81A and the second opening 82A have the same height, and are arranged above the highest inner bottom surface of the first communicating pipe portion and the highest inner bottom surface of the second communicating pipe portion. be done.

By arranging as described above, the water pumped from the pump 17 is temporarily stored in the third pipe 83, and this temporarily stored water flows through the first opening 81A and the second opening 81A. Water is evenly supplied from the portion 82A to the first humidification filter 12A and the second humidification filter 12B, and an improvement in humidification performance can be expected.

Moreover, not only the third pipe 83 but also the first pipe 19 (FIG. 2) and the second pipe 20 (FIG. 2) connecting the first supply part 81 from the pump 17 are made of a flexible material. should be used. As can be seen from FIG. 2 , the pump 17 is located on the back side of the body case 1 , while the supply section 15 is located on the front side of the body case 1 . By using a flexible material, water channels can be arranged freely.

16 is a cross-sectional perspective view of the IV-IV cross section of FIG. 15 as viewed in the direction of the arrow.

As shown in FIG. 2 , the first rear space 25 is divided into the air blower 3 and the space 85 by a vertical wall surface 84 . In the air passage 10 , the space 85 is located upstream of the air blower 3 and downstream of the humidifying filter 12 .

As shown in FIG. 16, an ion generator 86 is provided on a wall surface 84 on the air blower 3 side. The ions described here are radicals that react with hydroxyl groups (hydroxyl groups). They are very electrically unstable and try to steal missing electrons from surrounding atoms and molecules, so they are very oxidative. It is strong. This oxidizing action has the effect of decomposing odors. When these ions are released into the room, they decompose bad odors in the room.

Specifically, as shown in FIG. 16, the wall surface 84 is preferably provided with an attraction port 88 for attracting ions, and an ion generator 86 is provided at a position higher than the attraction port 88. . The ion generator 86 and the attraction port 88 are communicated with each other. Ions are emitted from the ion generator 86 to the space 85 as indicated by arrows in the induction air path 89 . When the air blower 3 is operated, the attracting port 88 becomes negative pressure, so the ions generated from the ion generator 86 are sucked into the communication hole 90 and supplied into the room. Further, when the operation of the air blowing section 3 is stopped, the space 85 can be filled with ions, and the filter section 62 can be effectively exposed to the ions.

Explaining the attraction port 88 in more detail, the attraction port 88 opens downward and, as shown in FIG. As a result, even if water scatters from the humidifying filter 12 , the water will not reach the ion generator 86 . Therefore, the stability or safety of the humidifying device can be ensured.

In addition, by providing the wall surface 84 at a position different from the communication hole 90 communicating with the blower section, ions are less likely to escape from the communication hole 90 to the blower section 3 . Therefore, it is effective in suppressing the odor of the filter portion 62 .

As a result, odors in the room and the filter section 62 can be suppressed while ensuring the stability or safety of the humidifying device.

Water supplied from the tank portion 31 is stored in the water storage container 11 during operation, and a constant water level 96 can be maintained. When the water in the tank portion 31 runs out, the water level 96 drops and can be detected by the water shortage detection device 97 inside the water storage container 11 .

A feature of this embodiment is that the pump 17 is provided at a position lower than the water level detected by the water shortage detection device 97 . That is, the water shortage can be detected while the pump 17 is covered with water. This allows the pump 17 to operate without sucking air. When the pump 17 sucks in air, there is a possibility that the life of the pump 17 may be shortened due to the generation of abnormal noise or idling of the pump 17 .

In addition, by leaving water in the water storage container 11 and draining the remaining water containing concentrated scale components and dirt, it is possible to extend the life of the main body.

At the lower end of the guide section 102, there is a drain port 103. Surplus water in the humidifying filter 12 reaches the recovery unit 101 by gravity. Surplus water in the collecting portion 101 is guided to the guide portion 102 and the drain port 103 in order, and is collected by the water storage container 11 arranged below the drain port 103 .

A feature of this embodiment is that a hill portion 104 (FIG. 17) higher than the water level 96 during operation is provided in the water storage container 11, and surplus water dripping from the drain port 103 falls into the hill portion 104. It is what I did. As a result, the distance over which the surplus water falls is shortened, and the surface on which the water falls is not the water surface indicated by the water level 96, so that the effect of not generating the sound of dripping water can be obtained.

As described above, the filter part 62 is made of a water-absorbing material and has a high water retention capacity. That is, it is in a water-retained state during operation and immediately after operation. Since the water is gradually recovered to the drain pan part 16 by gravity, the water stored in the filter part 62 cannot be recovered from the water storage container 11 when the water storage container 11 is pulled out during or immediately after the operation.

In this embodiment, as shown in FIG. 19, a stopper portion 105 made of a rubber material is provided on the drain port 103 side.

As a structure for blocking water, for example, a structure such as the stopper portion 105 as shown in the sixth embodiment is conceivable. In such a configuration, in order to supply water from the pump 17 , it is necessary to open the stopper portion 105 wide and connect the first connecting portion 22 . With such a configuration, water remaining in the second pipe 20 may leak out of the main body case 1 while the stopper portion 105 is closed.

A feature of this embodiment is that the non-return mechanism is provided in the water channel. With such a configuration, it is possible to immediately close the second connecting portion 23 by the check valve 111 when the water storage container 11 (the first connecting portion 22) is pulled out. As a result, the structure is such that residual water in the second pipe 20 is less likely to leak.

23 and 24 show perspective views of the check valve 111. FIG.

As shown in FIG. 23, the check valve 111 is provided with a cross-shaped check rib 113 at the tip of the conical side of a shape combining a cylinder and a cone. As shown in FIG. 24, the cylindrical side has an annular groove 114 and a pin-shaped projection 115 in the center. The non-return spring 112 is inserted into the groove 114 , and the projection 115 is inserted into the non-return spring 112 . 23 and 24, the check spring 112 is not shown.

The check rib 113 is arranged on the side of the first connecting portion 22 so that the cylindrical first connecting portion 22 can stably push the check valve 111 . A groove 114 and a protrusion 115 are provided on the side of the check spring 112 so that the check valve 111 can be stably driven without the check spring 112 coming off.

The water storage container handle 121 can move from a state inclined to the front side shown in FIG. 26 to a substantially vertical state shown in FIG.

When carrying the water container 11, the water container handle 121 may be pulled up vertically. In this case, when the water container 11 is set in the main body case 1 , the water container handle 121 contacts the lower portion of the front panel 41 . As a result, the water storage container handle 121 can be automatically retracted as shown in FIGS. 25 and 26 from the state in which it is pulled up vertically. Thus, the water storage container 11 can be conveniently set in the main body case 1 .

FIG. 28 shows step by step the operation when the tank part 31 is set in the water storage container 11 . The tank part 31 is provided with a freely movable tank handle 36 . The center of gravity when the tank 32 is filled with water and the position of the shaft of the tank handle 36 are different. That is, as shown in FIG. 28(a), when the tank portion 31 is set in the water storage container 11, the tank 32 is configured to tilt downward toward the front side when the tank is full.

Since there is a water storage container handle 121 on the front side of the tank 32 , it is necessary to set the tank part 31 so as to avoid the water storage container handle 121 .

When the tank 32 is full of water, it tilts downward toward the front side, so that when the tank part 31 is set in the water storage container 11, the water storage container handle 121 can be positioned above the front side of the tank 32. . 28(a)→(b)→(c), the tank portion 31 can be smoothly set in the water storage container 11 while the tank 32 avoids the water storage container handle 121.

From the state of FIG. 28(b), the bottom of the tank 32 comes into contact with the bottom of the water storage container 11, so that the tank 32 gradually shifts to the horizontal state (FIG. 28(b)→(c)).

In this manner, the user can correctly set the tank portion 31 in the water storage container 11 without being conscious of the mounting direction of the tank portion 31 .

As shown in FIGS. 29(a) and (b), the tank handle 36 may be retracted forward or backward.

As shown in FIG. 25, two sets of tank portions 31 may be provided. Since the tank 32 in a full state is considerably heavy (in the present embodiment, the total amount of stored water exceeds 10 liters), the burden of transportation is increased. By providing two sets of tank portions 31, the weight of each tank portion 31 can be reduced, and the effect of reducing the transportation load can be expected.

As shown in FIGS. 17 and 18, inside the water reservoir 11, a hill portion 104, a pump 17, a first pipe 19 and a first connection portion 22 are arranged.
