First, the configuration of a humidifying device 100 according to a first embodiment of the present invention will be described with reference to fig. 1. Fig. 1 is a cross-sectional view showing an example of the configuration of a humidifier 100 according to a first embodiment. In the first embodiment, the X axis, the Y axis, and the Z axis which are orthogonal to each other are shown in the drawing. The Z axis is parallel to the vertical direction, and the X axis and the Y axis are parallel to the horizontal direction. The positive direction of the X axis represents the front surface side of the humidifying device 100.
As shown in fig. 1, the humidifying device 100 includes a housing 10, a filter unit 3, a water tank 4, a motor 5, and a blower 6. The motor 5 is an example of a "driving unit".
The housing 10 includes a top plate 26, a bottom plate 27, side plates 29, a front panel 28, and a rear panel 24. The front panel 28, the rear panel 24, and the side panel 29 are disposed between the top plate 26 and the bottom plate 27, respectively.
The rear panel 24 is disposed opposite the front panel 28. The rear panel 24 is disposed on the negative side of the X axis of the housing 10. In the present specification, the positive direction of the X axis indicates a first direction D1 from the rear panel 24 toward the front panel 28. In addition, the negative direction of the X-axis indicates a second direction D2 opposite (opposite) to the first direction D1. The rear panel 24 has a plurality of suction ports 25. The suction ports 25 are open.
The top plate 26 is disposed opposite to the bottom plate 27. And is disposed above the housing 10. Top plate 26 has a plurality of air bleed ports 16. Each of the air feed ports 16 is an opening.
The housing 10 further includes a suction chamber 12, a discharge chamber 13, and a partition wall 11. The partition wall 11 partitions the suction chamber 12 and the discharge chamber 13. The suction chamber 12 is disposed on the second direction D2 side of the discharge chamber 13.
The frame 10 has a flow passage RA. Specifically, the suction chamber 12 communicates with the outside of the housing 10 via the plurality of suction ports 25. The discharge chamber 13 communicates with the outside of the housing 10 via the air supply ports 16. The suction chamber 12 and the discharge chamber 13 communicate with each other through an opening 11a provided in a lower portion of the partition wall 11. The suction port 25, suction chamber 12, opening 11a, discharge chamber 13, and air feed port 16 correspond to the flow passage RA.
First, the suction chamber 12 will be described in detail. The suction chamber 12 accommodates the filter unit 3, the water tank 4, and the motor 5. The suction chamber 12 is provided with a dust collection filter 22 and a deodorizing filter 23.
The deodorizing filter 23 is disposed on the first direction D1 side with respect to the rear panel 24. The deodorizing filter 23 adsorbs odor components contained in the air. The deodorizing filter 23 is, for example, a nonwoven fabric holding activated carbon.
The dust collection filter 22 is disposed on the first direction D1 side with respect to the deodorization filter 23. The dust collection filter 22 is laminated on the deodorizing filter 23. The dust collecting filter 22 collects dust contained in the air. The dust collecting Filter 22 is, for example, a HEPA Filter (High Efficiency Particulate Air Filter).
The partition member 21 is disposed on the first direction D1 side with respect to the dust collection filter 22. The partition member 21 has a plurality of openings 211.
Next, the discharge chamber 13 will be described in detail. The discharge chamber 13 accommodates the blower 6. The blower 6 is disposed opposite to the opening 11 a.
The blower 6 has a fan 60 and a motor 61. The motor 61 rotates the fan 60. Specifically, the center of the fan 60 is connected to the rotation shaft of the motor 61.
The fan 60 generates an air flow to pass the air through the filter unit 3. Specifically, the fan 60 is rotated by driving the motor 61. The fan 60 sucks air through the filter unit 3 and sends the air toward the first direction D1.
More specifically, air flows through the flow passage RA. Specifically, as shown in the direction D, air flows from the outside of the humidifying device 100 into the suction chamber 12 through the suction port 25 of the rear panel 24 by the rotation of the fan 60. The direction D represents the flow direction of the air. The inflowing air flows in the first direction D1 inside the suction chamber 12. Then, the air is sucked by the fan 60 through the opening 11 a. The traveling direction of the air is changed to the upward direction by the fan 60. Then, the air is discharged to the outside of the humidifying device 100 via the air-supply port 16.
The water tank 4 contains liquid. The liquid is for example water. The water tank 4 has a rectangular box shape. The upper surface of the water tank 4 is opened. The water tank 4 is disposed below the filter unit 3.
The water tank 4 has two support rollers 41. Specifically, the two support rollers 41 are respectively provided inside the water tank 4. The two support rollers 41 each rotate about the first direction D1 as a rotation axis. The two support rollers 41 are disposed in a direction intersecting the first direction and a direction intersecting the vertical direction at a predetermined distance.
Next, the filter unit 3 and the motor 5 of the first embodiment will be described with reference to fig. 2 and 3. Fig. 2 is a rear view showing the humidifying device 100. Fig. 3 is an exploded perspective view showing the filter unit of the first embodiment.
As shown in fig. 2 and 3, the filter unit 3 includes a first frame portion 310, a second frame portion 320, and a filter 31.
The first frame portion 310 covers the first direction D1 side of the filter 31. Further, the second frame portion 320 covers the second direction D2 side of the filter 31. In other words, the filter 31 is disposed between the first frame portion 310 and the second frame portion 320. The material of the first frame portion 310 and the second frame portion 320 is, for example, a synthetic resin.
The filter 31 is impregnated with liquid. For example, the filter 31 is a disc-shaped sheet. The sheet is formed of a material having water-absorbing properties and air-permeability. The sheet is formed of rayon, for example.
The first frame portion 310 has a cylindrical body 311 and a ring gear 32. The ring gear 32 is formed on the outer peripheral surface of the cylindrical body 311. Specifically, the ring gear 32 is teeth formed on the entire outer peripheral surface of the cylindrical body 311.
The filter unit 3 is disposed in the flow passage RA by placing the first frame portion 310 on the two support rollers 41. The lower part of the filter unit 3 is located inside the water tank 4, and the upper part of the filter unit 3 is located outside the water tank 4. In other words, the lower portion of the filter unit 3 is immersed in the water tank 4.
The motor 5 rotates the filter unit 3 about the rotation axis. The motor 5 is fixed to the partition member 21 and is disposed above the filter unit 3. The motor 5 is connected with a transmission gear which is meshed with the driving gear.
When the first frame portion 310 is placed on the two support rollers 41, the drive gear meshes with the ring gear 32. That is, the filter unit 3 is supported at three points at different positions in the circumferential direction by 2 support rollers 41 and a drive gear. As a result, the motor 5 is rotationally driven, and the drive gear rotates via the transmission gear. The rotation of the drive gear is transmitted to the cylindrical body 311 via the ring gear 32, and the filter unit 3 rotates about the first direction D1 as a rotation axis.
However, in the humidifier 100, the filter 31 needs to be cleaned or replaced for a predetermined period. When the user cleans or replaces the filter 31 for a predetermined period, the user takes out the filter unit 3 from the housing 10.
Next, the filter unit 3 of the first embodiment will be described in detail with reference to fig. 3 and 4. Fig. 4 is a perspective view showing the filter unit 3.
As shown in fig. 3 and 4, the filter unit 3 further includes a first connection portion 330 and a second connection portion 340.
The first connecting portion 330 connects the first frame portion 310 and the second frame portion 320. The second connecting portion 340 connects the first frame portion 310 and the second frame portion 320. The kind of the engaging structure of the first connecting portion 330 is different from that of the second connecting portion 340. For example, the engagement structure of the second connection portion 340 is a structure that is easier to separate the first frame portion 310 from the second frame portion 320 than the engagement structure of the first connection portion 330.
As described above with reference to fig. 1 to 4, the type of the engagement structure of the first connection portion 330 is different from the type of the engagement structure of the second connection portion 340. As a result, the first frame portion 310 and the second frame portion 320 can be separated from each other with ease in separating the first frame portion 310 and the second frame portion 320. Therefore, the filter 31 can be easily attached and detached. For example, the filter 31 can be easily replaced.
Next, the first connection portion 330 will be described in detail with reference to fig. 4 and 5. Fig. 4 is an enlarged sectional view of the first connection part 330. As shown in fig. 4 and 5, the first connection portion 330 includes: a first concave portion 331, a second concave portion 332, a first convex portion 333, and a second convex portion 334.
The second frame portion 320 is substantially quadrangular. Specifically, the second frame portion 320 includes four corner ring bodies 321, eight octagonal ring bodies 322, and eight connecting rods 323. The quadrangular ring 321 includes a first connecting portion 321a, a second connecting portion 321b, a third connecting portion 321c, and a fourth connecting portion 321d. The first connection portion 321a, the second connection portion 321b, and the fourth connection portion 321d are each shaped substantially linearly. The third connecting portion 321c is a plate-like body having a substantially circular arc. Specifically, the third connection portion 321c has a curved shape along the shape of the first frame portion 310. The length of the diagonal line of the quadrangular ring 321 is substantially the same as the length of the diameter of the cylindrical body 311. The octagonal ring body 322 is disposed within the four corner ring body 321. Eight connecting rods 323 are connected with the octagonal ring body 322 and the quadrangular ring body 321 respectively. Eight connecting rods 323 extend in the radial direction, respectively.
The first recess 331 is disposed at a first vertex of the four vertices of the quadrangular ring 321. Specifically, the first recess 331 is disposed between the fourth connection portion 321d and the first connection portion 321 a. The first recess 331 is recessed toward the first direction D1. The second recess 332 is disposed at a second vertex of the four vertices of the quadrangular ring 321. Specifically, the second recess 332 is disposed between the first connection portion 321a and the second connection portion 321b. The second recess 332 is recessed toward the first direction D1.
The first protrusion 333 is disposed on the first frame portion 310. Specifically, the first convex portion 333 extends from the inner peripheral surface of the cylindrical body 311 toward the center of the first frame portion 310. The first convex part 333 engages with the first concave part 331. Specifically, when the first frame portion 310 and the second frame portion 320 are connected, the first convex portion 333 is disposed in the first concave portion 331. As a result, the second frame portion 320 can be restricted from moving in the second direction D2 with respect to the first frame portion 310.
The second protrusion 334 is disposed on the first frame portion 310. Specifically, the second convex portion 334 extends from the inner peripheral surface of the cylindrical body 311 toward the center of the first frame portion 310. The second protrusion 334 engages with the second recess 332. Specifically, when the first frame portion 310 and the second frame portion 320 are connected, the second convex portion 334 is disposed in the second concave portion 332. As a result, the second frame portion 320 is restricted from moving in the second direction D2 with respect to the first frame portion 310.
As described above with reference to fig. 4 and 5, the first connection portion 330 includes the first recess 331, the second recess 332, the first protrusion 333, and the second protrusion 334. As a result, the separation of the first frame portion 310 and the second frame portion 320 can be restricted with a simple configuration.
Next, the second connection portion 340 will be described in detail with reference to fig. 4 and 6. Fig. 6 is an enlarged sectional view of the second connection portion 340. As shown in fig. 4 and 6, the second connection portion 340 includes a first claw member 341, a second claw member 342, a first hook member 343, and a second hook member 344.
The first claw member 341 is disposed at the peripheral edge portion of the first frame portion 310. Specifically, the first claw member 341 faces the first projection 333. The first claw member 341 has a plate-like body 341a and a projection 341b. The plate-like body 341a is disposed perpendicularly to the radial direction. The plate-like body 341a is fixed to the first frame portion 310 on the first direction D1 side. The protrusion 341b is disposed on the second direction D2 side of the plate-like body 341 a. The protrusion 341b extends toward the center of the second frame portion 320.
The first hook member 343 is disposed at the third vertex of the second frame portion 320. Specifically, the first hook member 343 is disposed in the vicinity between the second connection portion 321b and the third connection portion 321 c. Specifically, the first hook member 343 is disposed on the plate-like body of the third connecting portion 321c to prevent water from entering. The first hook member 343 has an opening 343c, a first protrusion 343a, and a first elastic member 343b. The first elastic member 343b is, for example, a plate-like body. The first elastic member 343b is disposed in the opening 343 c. The first elastic member 343b is disposed perpendicularly to the radial direction. The first elastic member 343b is fixed to the second frame portion 320 on the first direction D1 side. The first protrusion 343a is disposed on the second direction D2 side of the first elastic member 343b. The first protrusion 343a extends toward the outer circumference of the second frame portion 320. When the user moves the second direction D2 side of the first elastic member 343b toward the center of the second frame portion 320, the first protrusion 343a also moves toward the center of the second frame portion 320.
When the first frame portion 310 and the second frame portion 320 are connected, the first claw member 341 is inserted into the opening portion 343 c. The first protruding portion 343a is moved toward the center of the second frame portion 320, and the second frame portion 320 is disposed at a predetermined position with respect to the first frame portion 310. The first protrusion 343a is engaged with the first claw member 341 by preventing the first protrusion 343a from moving toward the center of the second frame portion 320. Specifically, when the first frame portion 310 and the second frame portion 320 are connected, the first protruding portion 343a is disposed on the first direction D1 side of the protruding portion 341b. As a result, the second frame portion 320 can be restricted from moving in the second direction D2 with respect to the first frame portion 310. Conversely, the first protruding portion 343a is moved toward the center of the second frame portion 320, and the second frame portion 320 is moved in the second direction D2 with respect to the first frame portion 310, whereby the first frame portion 310 and the second frame portion 320 can be separated from each other.
The second claw member 342 is disposed on the peripheral edge portion of the first frame portion 310. Specifically, the second claw member 342 is opposed to the second projection 334. The second claw member 342 has the same configuration as the first claw member 341. Specifically, the second claw member 342 has a plate-like body and a protrusion. The plate-like body is disposed perpendicularly to the radial direction. The plate-like body is fixed to the first frame portion 310 in the first direction D1. The protrusion is disposed on the second direction D2 side of the plate-like body. The protrusion extends toward the center of the second frame portion 320.
The second hook member 344 is disposed at a fourth vertex of the second frame portion 320. Specifically, the second hook member 344 is disposed in the vicinity between the third connection portion 321c and the fourth connection portion 321d. Specifically, the second hook member 344 is disposed on the plate-like body of the third connection portion 321c, and prevents water from entering. The second hook member 344 has the same configuration as the first hook member 343. Specifically, the second hook member 344 has an opening, a second protrusion, and a second elastic member. The second elastic member is, for example, a plate-like body. The second elastic member is disposed in the opening. The second elastic member is disposed perpendicularly to the radial direction. The second elastic member is fixed to the second frame portion 320 in the first direction D1. The second protrusion is disposed on the second direction D2 side of the second elastic member. The second protrusion extends toward the outer periphery of the second frame portion 320. When the user moves the second direction D2 side of the second elastic member toward the center of the second frame portion 320, the second protrusion also moves toward the center of the second frame portion 320.
When the first frame portion 310 and the second frame portion 320 are coupled, the second claw member 342 is inserted into the opening portion. The second projecting portion is moved toward the center of the second frame 320, and the second frame 320 is disposed at a predetermined position with respect to the first frame 310. By preventing the second protrusion from moving toward the center of the second frame portion 320, the second protrusion engages with the second claw member 342. Specifically, when the first frame portion 310 and the second frame portion 320 are connected, the second protruding portion is disposed on the first direction D1 side of the protruding portion. As a result, the second frame portion 320 can be restricted from moving in the second direction D2 with respect to the first frame portion 310. Conversely, by moving the second protruding portion toward the center of the second frame portion 320, the second frame portion 320 is moved in the second direction D2 with respect to the first frame portion 310, and the first frame portion 310 and the second frame portion 320 can be separated.
As described above with reference to fig. 5 and 6, the second connection portion 340 includes the first claw member 341, the second claw member 342, the first hook member 343, and the second hook member 344. As a result, after the connection between the first frame portion 310 and the second frame portion 320 is released by the second connection portion 340, the connection between the first frame portion 310 and the second frame portion 320 can be released by the first connection portion 330. This makes it possible to easily separate the first frame portion 310 and the second frame portion 320. After the first frame portion 310 and the second frame portion 320 are connected by the first connection portion 330, the first frame portion 310 and the second frame portion 320 can be connected by the second connection portion 340. Therefore, the first frame portion 310 and the second frame portion 320 can be easily connected.
More specifically, when the first frame portion 310 and the second frame portion 320 are connected, first, the first convex portion 333 is engaged with the first concave portion 331, and the second convex portion 334 is engaged with the second concave portion 332. Next, the second frame portion 320 is moved toward the first frame portion 310 with a line connecting the first protrusion 333 and the second protrusion 334 as a rotation axis. Next, the first protruding portion 343a and the second protruding portion are moved toward the center of the second frame portion 320. Next, the second frame portion 320 is disposed at a predetermined position with respect to the first frame portion 310. By preventing the first protruding portion 343a and the second protruding portion from moving toward the center of the second frame portion 320, the first protruding portion 343a and the first claw member 341 are engaged, and the second protruding portion and the second claw member 342 are engaged. As a result, the first frame portion 310 and the second frame portion 320 can be more easily connected.
More specifically, the first protrusion 333, the second protrusion 334, the first claw member 341, and the second claw member 342 are arranged in this order around the central axis of the first frame portion 310. As a result, the user can easily separate the first frame portion 310 and the second frame portion 320 by operating the first hook member 343 with the right hand and the second hook member 344 with the left hand.
More specifically, the first frame portion 310 has a substantially circular shape, and the second frame portion 320 has a substantially rectangular shape in which the first concave portion 331, the second concave portion 332, the first hook member 343, and the second hook member 344 are arranged in this order at the vertex of the second frame portion 320. As a result, since the first frame portion 310 and the second frame portion 320 do not contact as much as possible, even if the second frame portion 320 floats with respect to the first frame portion 310, deterioration in appearance can be suppressed.
< second embodiment >
The structure of the filter unit 3 according to the second embodiment of the present invention will be described with reference to fig. 7. Fig. 7 is a perspective view showing the filter unit 103.
In contrast to the filter unit 3 of the first embodiment in which the second connection portion 340 includes the first claw member 341, the second claw member 342, the first hook member 343, and the second hook member 344, the filter unit 103 of the second embodiment differs in that the second connection portion 340 includes the first claw member 341 and the first hook member 343. In other words, the second connection portion 340 does not include the second claw member 342 and the second hook member 344.
The second frame portion 1320 is substantially semicircular. Specifically, the second frame portion 1320 includes a substantially semicircular ring 1321, a ring 1322, and eight connecting rods 323.
