Description

  The present invention relates to a humidifier configured to pass air through a humidified filter impregnated with water and send the air to the downstream side of the humidified filter.

  In recent years, humidifiers that give appropriate humidity to indoor air have been widely used, and in particular, vaporizing humidifiers that achieve humidification without water evaporation do not affect the indoor temperature. Since the humidity can be adjusted, its spread is expanding.

  The vaporizing type humidifier has a humidifying filter impregnated with water inside the air passage connecting the air inlet and the air inlet, together with the air blower fan, and the air blower fan moves from the air inlet to the air passage. The air to be introduced is passed through the humidifying filter, and humid air containing vaporized water sent to the downstream side of the humidifying filter is sent out through the air supply port.

  The humidifying filter is constructed by folding a sheet made of a material (nonwoven fabric, etc.) having high water content and allowing ventilation into a bellows shape, soaking the lower part in a water storage dish, and sucking up the water stored in the water storage dish. The water lost by vaporization is replenished. A water supply tank is attached to one side of the water storage tray, and water in the water supply tank is sequentially introduced into the water storage tray according to the decrease in the water level due to the suction of the humidifying filter, so that a fixed amount of water is always stored. It is constituted as follows.

  The water supply tank is a cylindrical hollow container, and has a water supply port opened at one end. The water supply port is provided with a water stop lid provided with a water stop valve, and the water supply tank is held in a vertical posture with the water supply port facing downward in a holding part connected to one side of the water storage dish. At this time, the water stop valve is pushed up and opened by a protrusion provided on the holding portion, and the water in the water supply tank is sent to the water storage dish through the water stop valve.

  When the water in the water supply tank is reduced, the user removes the water supply tank from the holding portion, and replenishes the water with the water supply port from which the water stop cover is removed facing the tap. This replenishment can be carried out stably, for example, by supporting the water supply tank in a standing posture with the water supply port facing upward on the bottom surface of the sink provided with the faucet, but the separation distance between the faucet and the bottom surface is sufficient. In other cases, the faucet and the water supply port cannot be made to face each other. In this case, there is a problem that the user is forced to perform an unstable replenishment work by supporting the water supply tank by hand.

  In patent document 1, the flat part which cut | disconnected the corner | angular part of the other side (opposite side to a water supply port) of the water tank which makes a rectangular tube shape was provided, and the position of a water supply port is used by utilizing this flat part. The above problem can be solved by making it possible to support in a lowered oblique position. Furthermore, a handle for carrying the water supply tank is used, and it is said that this handle and the flat portion can stably support in an oblique posture.

  However, in the water supply tank disclosed in Patent Document 1, the change in the position of the water supply port due to the oblique support using the flat portion is limited, and it is difficult to stabilize the replenishment work under a wide range of usage conditions. .

  For example, the humidifier as described above is widely used not only in ordinary households but also in hotel guest rooms. Water supply to the water supply tank under such conditions of use is carried out in the washroom attached to the cabin, but the distance between the faucet and the bottom surface of the wash bowl is small, and the bottom surface of the wash bowl is flat. Therefore, even if the water supply tank disclosed in Patent Document 1 is used, it is difficult to realize a replenishment operation in a stable support state.

  This invention is made | formed in view of such a situation, and it aims at providing the humidifier which can implement stably the water supply to the water supply tank under various use conditions.

(Embodiment 1)
FIG. 1 is an external perspective view of the humidifier according to the first embodiment, and FIG. 2 is a side sectional view showing a schematic configuration of the humidifier according to the first embodiment. 2 shows the front as the left and the back as the right, and FIG. 1 is a perspective view seen from the back side (the right side in FIG. 2).

  As shown in FIG. 2, the humidifier includes a blower fan 2, a humidifying filter 3, and a water storage dish 4 inside a rectangular box-shaped housing 1. The interior of the housing 1 is divided by a partition wall 11 into a suction chamber 12 on the back side and a discharge chamber 13 on the front side. The suction chamber 12 communicates with the outside through a plurality of intake ports 15 provided in the back panel 14 covering the back surface of the housing 1, and the discharge chamber 13 is provided with an air supply port 16 provided in the top plate of the housing 1. The suction chamber 12 and the discharge chamber 13 are communicated with each other through a vent hole 11 a provided at the lower portion of the partition wall 11.

  The back panel 14 is detachable, and a deodorizing filter 17 and a dust collecting filter 18 are laminated inside the back panel 14. The deodorizing filter 17 is formed by, for example, dispersing and holding activated carbon in a non-woven fabric, and acts to adsorb and remove odorous components being ventilated. The dust collection filter 18 is, for example, a HEPA (High Efficiency Particulate Air) filter, and acts to collect and remove fine dust contained in the ventilation. The deodorizing filter 17 and the dust collecting filter 18 are respectively held by resin frame bodies 17a and 18a, and are detachably fitted and held in a filter chamber provided inside the back panel 14. In FIG. 1, the back panel 14, the deodorizing filter 17, and the dust collecting filter 18 are removed.

  The blower fan 2 includes an impeller 20 and a fan motor 21 that drives the impeller 20. The fan motor 21 is fixedly supported on the front wall of the discharge chamber 13. The impeller 20 is fixed to the output end of the fan motor 21 protruding inside the discharge chamber 13, and is disposed opposite to the vent 11 a at the lower part of the partition wall 11. The impeller 20 of the blower fan 2 is rotated by driving a fan motor 21.

  When the impeller 20 rotates, outside air is introduced into the suction chamber 12 through the intake port 15 as indicated by white arrows in FIG. The introduced outside air passes through the deodorizing filter 17 and the dust collecting filter 18 to become clean air from which odorous components and dust are removed, and is sucked into the impeller 20 through the vent 11a and changed in the upward direction to the discharge chamber. 13 and is sent to the outside through the air supply port 16.

An ion generator 19 is provided in the discharge chamber 13. For example, the ion generator 19 ionizes oxygen and water in the air by discharging, positive ions such as H ⁺ (H ₂ O) _m (m is an arbitrary integer), and O ²⁻ (H ₂ O) _n. It is configured to generate negative ions such as (n is an arbitrary integer). Ions generated by the ion generator 9 are sent out along with the ventilation in the discharge chamber 13 and attach to the surface of bacteria and viruses floating in the delivery space, and function to sterilize or inactivate them.

  The illustrated humidifier also functions as an air purifier due to the arrangement of the deodorizing filter 17, the dust collection filter 18 and the ion generator 19. The ion generator 19 can employ a known appropriate configuration such as a configuration in which high voltage is applied to condensation on the cooled electrode to generate mist-like charged water particles.

  The humidification filter 3 and the water storage tray 4 are arranged between the deodorizing filter 17 and the dust collection filter 18 and the blower fan 2 in order to humidify the air flowing in the housing 1 as described above.

  The water storage tray 4 is placed on the bottom plate of the housing 1 with the opening side facing upward. As shown in FIG. 1, the water storage tray 4 can be pulled out from one side of the housing 1, and a wide holding portion 40 is connected to the end portion on the drawer side. The water supply tank 5 is detachably held by the holding portion 40. FIG. 1 shows the water tank 5 removed. The configuration of the water supply tank 5 will be described later.

  The humidification filter 3 is a highly moisture-containing material that can be ventilated, for example, a non-woven sheet, and is folded in a bellows shape to increase the contact area with the aeration described later, and the inside of the hollow disk-shaped holding frame 30. Is stored and held.

  3 is a cutaway front view of the main part showing the support structure of the humidifying filter 3, and FIG. 4 is a perspective view of the same. 3 and 4, only the holding frame 30 of the humidifying filter 3 is shown. The humidifying filter 3 is placed on two support rollers 6 and 6 provided inside the water tray 4 as shown in FIG. 3 by inserting the lower part of the holding frame 30 into the water tray 4. The support rollers 6 and 6 are arranged at an appropriate distance in the longitudinal direction of the water storage dish 4, and the humidifying filter 3 is mounted on the support rollers 6 and 6 by placing the holding frame 30 on the support rollers 6 and 6. As shown in FIG. 4, it is supported in a vertically rising posture on the water storage dish 4, and can be rotated around the central axis while maintaining the supporting posture by the rolling of the support rollers 6 and 6.

  As shown in FIG. 1, the humidifying filter 3 supported in this way can be drawn out together with the water storage dish 4 from one side of the housing 1, and conversely, is pushed into the housing 1 together with the water storage dish 4, It can be set at a predetermined position inside the housing 1.

  As shown in FIG. 4, a ring gear 31 having an appropriate width is provided on the outer peripheral surface of the holding frame 30 over the entire circumference. As shown in FIGS. 2 and 3, the ring gear 31 is engaged with a drive gear 70 attached to the output end of the drive motor 7 fixedly supported by the partition wall 11. The drive gear 70 rotates around an axis that is parallel to the holding frame 30 of the humidifying filter 3 by driving the drive motor 7.

  The meshing between the drive gear 70 and the ring gear 31 occurs when the humidifying filter 3 is set in the housing 1 as described above. By this meshing, the holding frame 30 is supported at three points by the two support rollers 6 and 6 inside the water tray 4 and the drive gear 70, and the humidifying filter 3 is driven by the drive motor 7. It rotates at a low speed around the central axis of the holding frame 30 according to the rotation. The support rollers 6 and 6 function as driven rollers that roll according to the rotation of the holding frame 30 and do not hinder the rotation of the humidifying filter 3.

  Inside the water reservoir 4, water at a reference water level indicated as L in FIG. 3 is stored. The lower part of the humidifying filter 3 that rotates as described above is immersed in the stored water of the water storage dish 4, and the humidifying filter 3 sucks up the stored water and lifts it up by rotation. As a result, the water stored in the water storage tray 4 spreads over the entire humidifying filter 3 and is impregnated and held in the humidifying filter 3.

  Thus, the air flowing in the housing 1 as described above passes through the humidifying filter 3 that holds water. The water retained in the humidifying filter 3 is vaporized by contact with the ventilation, and humid air containing vaporized water is sent out to the discharge chamber 13 on the downstream side of the humidifying filter 3, and the outlet is opened at the end of the discharge chamber 13. 16 is sent out.

  3 and 4, a holding unit 40 connected to one side of the water storage tray 4 is shown. A push-up protrusion 41 is erected vertically upward from the bottom plate inside the holding portion 40, and the push-up protrusion 41 is surrounded by a seat plate 42 projecting inward from the side plate at a position separated from the bottom plate by an appropriate length. ing. In addition, the holding unit 40 includes a support plate 43 erected on the connecting portion with the water storage dish 4 so as to be substantially perpendicular to the bottom plate.

  FIG. 5 is a front view of the water supply tank 5, and FIG. 6 is a longitudinal sectional view of the water supply tank 5 taken along line VI-VI in FIG. As shown in the figure, the water supply tank 5 is a rectangular tube-shaped hollow container with both ends in the axial length direction closed, and a water supply port 50 is opened in one end plate in the axial length direction. A screwed water stop lid 51 is attached to the water supply port 50. The water stop lid 51 incorporates a known water stop valve 52 having a valve body seated from the inside on a valve seat provided in the center. The valve body of the water stop valve 52 has an action end protruding outward from the central portion of the water stop lid 51, and is separated from the valve seat by pushing the action end inward.

  A handle 53 is attached to the other side end of the water supply tank 5. The handle 53 is swingable about a pivot on one side, and is overlapped with the outer surface of the water supply tank 5, a gripping position that is swung approximately 90 ° from the overlap position and rises from the outer surface of the water supply tank 5, Further, it is possible to realize a support position that further swings by approximately 90 ° from the gripping position and extends in a direction opposite to the overlapping position. In FIG. 6, the handle 53 at the overlapping position is indicated by a solid line, and the handle 53 at the gripping position and the support position is indicated by a two-dot chain line.

  Further, as shown in FIG. 5, a circular concave portion 54 is provided on one side surface of the water supply tank 5, and a replenishing water port 55 is opened at the center of the bottom surface of the concave portion 54. The replenishing water port 55 is covered with a screw-in lid 56 so as to be opened and closed, and a sealing ring 57 (sealing member) made of an elastic material is attached to the opening peripheral edge of the recess 54. Furthermore, the other side surface of the water supply tank 5 is covered with an exterior plate 58 over substantially the entire surface, as shown in FIG. Note that the lid 56 is not limited to the screw-in type, and may be configured to be opened and closed by fitting to the replenishing water port 55, for example.

  As shown in FIGS. 1 and 3, the water supply tank 5 configured as described above is attached to and detached from the holding unit 40 in an inverted posture with the water stop lid 51 facing downward. This attachment and detachment can be easily performed by gripping the handle 53 that is swung to the gripping position. At this time, the water stop valve 52 built in the water stop cover 51 is pushed downward by the biasing force of the spring attached to the valve body and the weight of the water stored in the water supply tank 5 so that the valve seat and the valve body are in close contact with each other. Since the closed state is maintained, there is no possibility that the water stored in the water supply tank 5 leaks out.

  FIG. 7 is an explanatory diagram of the holding state of the water supply tank 5. The water supply tank 5 is held as shown in the figure by supporting the water stop lid 51 from below by the seat plate 42 inside the holding portion 40 and supporting one side surface provided with the recess 54 by the support plate 43. At this time, the push-up protrusion 41 erected on the water storage tray 4 is inserted into the center portion of the water stop lid 51 and pushes up the valve body of the water stop valve 52 protruding to the position. By pushing up, the valve body of the water stop valve 52 is separated from the valve seat, the water stop valve 52 is opened, and the water supply tank 5 communicates with the holding unit 40 and the water storage dish 4.

  The exterior plate 58 that covers the other side surface of the water supply tank 5 forms a part of the exterior of the housing 1 by pushing the holding portion 40 and the water storage dish 4 that hold the water supply tank 5 into the housing 1.

  The support height of the water stop lid 51 by the seat plate 42 is matched with the reference water level L inside the water tray 4. The water stored in the water supply tank 5 passes through the open water stop valve 52 when the internal water level of the water storage dish 4 is lower than the reference water level L and a gap is formed between the water stop tank 51 and the water stop lid 51. It is sent to the holding part 40 and the water storage tray 4 by replacement with the introduced air. With the above operation, the water at the reference water level L can be constantly stored in the water tray 4.

  As shown in FIG. 7, the support ring 43 that supports the side surface of the water supply tank 5 is in elastic contact with a seal ring 57 provided at the periphery of the recess 54, and the seal ring 57 seals the inside of the recess 54 in a liquid-tight manner. To act. The water supply tank 5 has a replenishment water port 55 inside the recess 54. The replenishing water port 55 is closed by the lid 56, but if the closing is incomplete, the water stored in the water supply tank 5 may leak through the replenishing water port 55.

  The seal ring 57 functions to prevent the leaked water generated in this way from inside the recess 54 and prevent leakage to the outside. Therefore, it is possible to suppress an increase in the internal water level of the water storage tray 4 due to water leaking from the makeup water inlet 55, and to prevent overflow from the upper edge of the water storage tray 4.

  The seal ring 57 may be provided not on the water supply tank 5 but on the support plate 43 and elastically contact the peripheral edge of the recess 54 to fulfill the sealing function. Also in this configuration, leaking water from the replenishing water port 55 can be stopped inside the recess 54 by the action of the seal ring 57.

  The amount of water stored in the water supply tank 5 is gradually reduced by feeding to the holding unit 40 and the water storage tray 4. When the stored water decreases, the user removes the water supply tank 5 from the holding unit 40 and carries it to replenish the stored water. As shown in FIG. 1, the water supply tank 5 is removed by pulling out the water storage tray 4 to the outside of the housing 1 and holding the handle 53 swinging to the holding position and pulling it upward as described above.

  8 and 9 are explanatory diagrams of a method for supplying water to the water supply tank 5. FIG. 8 shows a water supply method at a water supply point where a flat support surface 8 (for example, the bottom surface of a kitchen sink) can be secured at a position away from the water supply source faucet 9. Different replenishment methods can be employed depending on the distance between the end and the support surface 8.

When the separation distance H ₁ between the water supply end of the faucet 9 and the support surface 8 is large, the water supply tank 5 stands on the support surface 8 with the water supply port 50 from which the water stop lid 51 is removed facing upward as shown in FIG. 8A. The water supply tank 5 is replenished with water discharged from the faucet 9 that is supported in the vertical posture and is opposed to the water supply port 50. At this time, by swinging the handle 53 to the above-described support position, the handle 53 functions as a support member, the contact area with the support surface 8 is increased, and water can be replenished in a stable support state. Become.

On the other hand, if the separation distance of H ₂ and the water supply end and the support surface 8 of the faucet 9 is small, the water supply tank 5, as shown in FIG 8B, the support in the horizontal posture and an upward replenishment Mizuguchi 55 has been removed the lid 56 In this state, the water discharged from the faucet 9 facing the water supply port 50 can be replenished.
