The first connecting portion 22 and the second connecting portion 23, which are the connecting units 21, communicate the first pipe 19 and the second pipe 20. The water sent to the first pipe 19 by the pump 17 is sent to the second pipe 20 having a tubular shape via the connecting unit 21. The other end of the second pipe 20 is connected to the supply section 15. The second pipe 20 extends from the second space portion 6 to the first space portion 5 via the first communication portion 4A which is a hole in the partition plate portion 4. The outer surface of the second pipe 20 is fitted in the hole which is the first communication portion 4A, and there is substantially no gap between the second pipe 20 and the first communication portion 4A. is there.

The supply unit 15 is arranged above the humidifying filter 12, and drops the water sent from the second pipe 20 onto the humidifying filter 12.

The drain pan portion 16 is arranged below the lower end portion of the humidifying filter 12 and is fixed to the partition plate portion 4. The drain pan portion 16 extends from the first space portion 5 to the second space portion 6 via the second communication portion 4B which is a hole in the partition plate portion 4. The excess water that is not retained by the humidifying filter 12 is returned to the water storage container 11 via the drain pan portion 16. The outer surface of the drain pan portion 16 is fitted in the hole which is the second communication portion 4B, and there is substantially no gap between the drain pan portion 16 and the second communication portion 4B.

The first space portion 5 is divided into two spaces, a first front space portion 24 and a first back space portion 25, by a supply unit 15, a humidifying filter 12, and a drain pan unit 16. The first front space portion 24 is a space on the front side of the humidifying filter 12, and the first back space portion 25 is a space on the back side of the humidifying filter 12.

The blower portion 3 is fixed to the first back space portion 25. The blower portion 3 includes a scroll-shaped casing 26, a motor 27 fixed to the casing 26, and blades 28 rotated by the motor 27. The casing 26 is provided with a discharge port 29 on the upper surface and an intake port 30 on the front surface side. The intake port 30 of the casing faces the humidifying filter 12 and the suction port 7.

As shown in FIG. 2, a tank portion 31 is provided in the water storage container 11.

As shown in FIG. 3, the tank portion 31 includes a tank 32 for storing water, a lid 34 provided at the tank opening 33 of the tank 32, and a valve mechanism 35 for supplying water in the tank 32.

The tank 32 has a box shape, and in a state where the tank portion 31 is mounted in the water storage container 11, a tank handle 36 is provided on the top surface of the tank 32, and a tank opening 33 is provided on the lower surface of the tank 32.

The humidification operation in the above configuration will be described. When the pump 17 is driven by the pump motor 18, the pump 17 sucks up the water in the water storage container 11 and sends the water to the supply unit 15 via the first pipe 19, the connecting unit 21, and the second pipe 20. The supply unit 15 drops the water sent from the second pipe 20 onto the humidifying filter 12. The humidifying filter 12 retains a part of the dropped water. The excess water that is not retained by the humidifying filter 12 is returned to the water storage container 11 via the drain pan portion 16. In this state, when the blades 28 are rotated by the motor 27 of the blower unit 3, the air outside the main body case 1 is sucked into the first space portion 5 from the suction port 7 and blown to the humidifying filter 12. Air is humidified when passing through the humidified filter 12 that retains water, and the humidified air is blown from the air outlet 8 to the outside of the main body case 1 through the intake port 30 and the discharge port 29 of the air blowing unit 3.

FIG. 4 is an exploded perspective view showing the humidifying device according to the first embodiment of the present invention. As shown in FIG. 4, a front panel 61 and a pre-filter 62 are provided on the upstream side of the humidifying filter 12.

The pre-filter 62 is provided on the front panel 61 and plays a role of preventing dust and the like from entering the main body.

The front panel 61 is provided with an elastic hook 63 on the lower side surface.

The front panel 61 forms a part of the main body case 1 by being attached to the corresponding portion of the main body case 1 via the hook 63.

As shown in FIG. 4, the feature of the present embodiment is that the front panel 61, the pre-filter 62, the humidifying filter 12, the drain pan portion 16, and the water storage container 11 are detachable from the front surface of the main body case 1. ..

As described above, the water storage container 11 is provided with a tank portion 31 and a pump 17. In a general humidifier, scales and impurities contained in tap water adhere to the water channel. Further, dust and the like contained in the air are collected by the pre-filter, and minute dust that has passed through the pre-filter 62 adheres to the humidifying filter 12. That is, the pre-filter 62, the humidifying filter 12, the drain pan portion 16, the pump 17, the tank portion 31, and the water storage container 11 need to be regularly maintained.

By making these components removable from the front surface of the main body case 1, maintenance can be easily performed without moving the main body. That is, it improves the usability of the user.

The shape of the humidifying filter 12 will be described in detail.

FIG. 5 is a perspective view of the humidifying filter 12 as viewed from the windward side.

FIG. 6 is a perspective view of the humidifying filter 12 as viewed from the leeward side.

As shown in FIGS. 5 and 6, the humidifying filter 12 is composed of a filter frame 41 molded of resin or the like and a fibrous filter portion 42 having water absorption.

As shown in FIG. 5, there is an inflow portion 43 for supplying water in the upper part of the filter frame 41. In the present embodiment, the inflow portion 43 is provided on the leeward side of the filter frame 41, but it may be provided on the leeward side of the filter frame 41 instead of being provided on the leeward side of the filter frame 41.

FIG. 7 is a partial cross-sectional view of the II-II cross section of FIG. 5 as viewed from the direction of the arrow. As shown in FIG. 7, the filter unit 42 is composed of a plurality of filters 44 in the direction of the air passage 10 and is configured to supply water to the filter 44 on the windward side as represented by the water channel 45. The supply unit 15 has an inflow portion 43 and a water channel 45.

The air passing through the filter unit 42 passes while gradually increasing the humidity while depriving the filter unit 42 of water. That is, the air passing through the filter unit 42 has the lowest humidity when passing through the first layer filter 44 on the windward side, and passes through the filter 44 on the leeward side (fourth layer in the case of FIG. 7). When you do, the humidity is the highest. That is, by supplying water to the filter 44 on the windward side, water can be supplied so as to compensate for the large amount of evaporation, so that humidification can be performed most efficiently. On the other hand, the filter 44 on the leeward side is sufficiently flooded by the action of blowing air. As a result, the filter unit 42 can be evenly flooded over a wide area, and the humidification performance can be improved.

Further, by forming the filter unit 42 with a plurality of layers of filters 44, one filter 44 can be made thin, so that maintenance becomes easy. In particular, since the filter 44 on the windward side has a large amount of moisture absorption and desorption, impurities contained in tap water and minute dust in the room are likely to accumulate. By configuring the filter unit 42 with a plurality of filters 44, only the windward filter 44 can be cleaned or replaced as needed. As a result, the life of the filter unit 42 can be improved.

As the plurality of filters 44 in FIG. 7, independent filters can be used for each layer.

Further, the filter 44 may be sewn into a tubular shape as shown in FIG. In FIG. 8, instead of using an independent filter for each layer, for example, two tubular filters 44 are used to form a four-layer structure. FIG. 8 shows a state in which the filter portion 42 is removed from the filter frame 41 and viewed from the windward side (left side in FIG. 7). Since the tubular filter 44 has elasticity, it has a property of expanding in an elliptical shape as shown in FIG. 8 when it is removed from the filter frame 41. Actually, since the filter 44 is attached to the filter frame 41, the layers are connected without a gap as shown in the filter 44 of FIG.

The filter 44 in FIG. 8 uses a knitting method that is easily flooded in the lateral direction X. By sewing the filter 44 into a tubular shape, the water supplied to the first layer can easily be infiltrated into the second layer by utilizing the characteristic that the water is easily infiltrated in the lateral direction X. Further, the water supplied to the third layer is likely to be infiltrated into the fourth layer by utilizing the characteristic that the water is easily infiltrated in the lateral direction X. As a result, the humidification performance can be improved. Although two tubular filters 44 are used, one or a plurality of tubular filters 44 may be used.

FIG. 9 is an exploded perspective view of the filter frame 41. The filter frame 41 is composed of a leeward side filter frame 46 and a leeward side filter frame 47. With such a configuration, the filter portion 42 can be easily removed from the filter frame 41, and maintenance becomes easy. Further, the leeward side filter frame 46 and the leeward side filter frame 47 are provided with pins 48 extending toward the filter portion 42 at equal intervals. That is, the pin 48 of the leeward filter frame 46 extends in the leeward direction, and the pin 48 of the leeward filter frame 47 extends in the leeward direction. Since the pin 48 is configured to be pierced by the filter portion 42, the filter portion 42 can be held in a regular position without being displaced by its own weight.

Further, the leeward filter frame 46 is shallower than the leeward filter frame 47. That is, in the direction in which air flows, the thickness of the leeward filter frame 46 is smaller than the thickness of the leeward filter frame 47.

As described above, the windward filter 44 is easily soiled, but similarly, the windward filter frame 46 is also easily soiled. That is, by making the leeward side filter frame 47 that is hard to get dirty and the windward side filter frame 46 shallow, it is easy to handle the leeward side filter frame 46 that is easy to get dirty, and as a result, maintenance becomes easy.

Further, as shown in FIG. 10, the filter frame 41 is provided with the attachment / detachment detecting means 49. This is to stop the operation of the blower unit 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 removed due to maintenance or the like is forgotten to be attached or when it is not assembled correctly. As an example of the attachment / detachment detecting means 49, it is composed of a magnet incorporated in the filter frame 41 and a sensor incorporated in the main body case 1 capable of detecting the magnet, and detects when the magnet and the sensor are separated by a certain distance or more. There is a configuration and so on.

As shown in FIG. 10, the lower end of the humidifying filter 12 is housed in the drain pan portion 16 (FIG. 4), and the upper part is stopped by the movable stopper 50. The humidifying filter 12 can be switched between the fixed state and the released state by the stopper 50.

As shown in FIGS. 5 to 7 and 9, the feature of the present embodiment is that the filter frame 41 above the filter unit 42 has a water splash suppressing unit 51 that suppresses water splashing from the filter unit 42. It is a point.

For example, the filter unit 42 is arranged in the filter frame 41, but if it is arranged downward in the filter frame 41, a gap is formed between the filter unit 42 and the upper part of the leeward filter frame 47. The air blown by the blower unit 3 may make it easier for the water dripping from the supply unit 15 of the windward side filter frame 46 to be blown to the leeward side. As a countermeasure, a shape that covers the entire gap between the filter portion 42 and the filter frame 41 can be considered, but in this case, the humidifying area is reduced as a result, resulting in a decrease in the humidifying capacity.

In such a case, the water splash suppression unit 51 has a water supply regulation unit 54 provided above the filter frame 41 (windward filter frame 46). The water supply regulation unit 54 has a shape extending downward from the lower end of the supply unit 15 of the windward filter frame 46 toward the windward side of the filter unit 42, and extends below the upper end of the filter unit 42. The water dripping from the supply unit 15 is supplied to the filter unit 42 while being guided by the water supply regulation unit 54 and transmitted only to the water supply regulation unit 54. As a result, even if there is a gap between the filter unit 42 and the filter frame 41 through which the wind passes, the water does not drip except for the water supply regulation unit 54, so that the water is not blown off by the wind. Further, although not shown, the water supply regulation unit 54 is provided with windproof ribs on both sides so that the water traveling through the water supply regulation unit 54 is not blown by the wind. As described above, since it is possible to suppress water splashing that is not subjected to humidification, as a result, it is possible to reduce a decrease in the humidifying capacity.

Further, as the water splash suppression unit 51, the water supply regulation unit 54 has a filter support unit 56 extending from the water supply regulation unit 54 to the filter unit 42 side. The filter support portion 56 is a rod-shaped pin extending from the water supply regulation portion 54 toward the filter portion 42. Since this pin is configured to be pierced by the filter portion 42, the filter portion 42 can be held in a regular position without being displaced by its own weight. As long as the user inserts the filter unit 42 into the filter support unit 56, the upper end of the filter unit 42 will be arranged above the lower end of the water supply regulation unit 54, so that the water transmitted through the water supply regulation unit 54 Will surely supply water to the filter unit 42. In this way, it is possible to suppress water splashing that is not subjected to humidification, and as a result, it is possible to reduce a decrease in the humidifying capacity.

Further, the water splash suppression unit 51 has a cover unit 55 provided on the filter frame 41 so as to face the water supply regulation unit 54 with the filter unit 42 interposed therebetween. The cover portion 55 is provided on the filter frame 41 on the leeward side of the filter portion 42 so as to face the water supply regulation portion 54 in the blowing direction. The cover portion 55 will be arranged on the leeward side filter frame 47. Since the cover portion 55 is located leeward of the water supply regulation unit 54, the wind speed around the water supply regulation unit 54 can be reduced. If the wind speed of the wind that blows against the water flowing through the water supply regulation unit 54 becomes low, the possibility of water splashing can be reduced. The cover portion 55 is not limited to the shape of the present embodiment because the effect of reducing the wind speed can be obtained if the cover portion 55 has a shape that includes the projected shape of the water supply regulation portion 54. As described above, since it is possible to suppress water splashing that is not subjected to humidification, as a result, it is possible to reduce a decrease in the humidifying capacity.

The humidifying device according to the present invention is useful as a humidifying device or the like used for home use or office use.
