BACKGROUND OF THE INVENTION
The present invention relates to a vaporizing humidifier.
[0002]
[Prior art]
[Patent Literature]
In a conventional vaporizing humidifier, a drum-type humidifying filter is horizontally disposed in a horizontally long box-type main body, and is rotated by a motor while the lower part is immersed in water in a water tank. A method of blowing air from a blower to humidify it has been known for a long time. (For example, Japanese Utility Model Publication No. 56-21138)
On the other hand, in the humidifiers that have been on the market in recent years, the main body has a vertical design, and the lower part of the horizontal rectangular vaporization filter is immersed in the water in the aquarium to prevent mold, odors, etc. from adhering to the filter. Therefore, there is a method in which the vaporization filter is rotated obliquely and dried while the vaporization filter comes out of the water. However, this patent document has not been published yet.
[0003]
These conventional examples will be described below with reference to the drawings.
[0004]
First, the vaporizer-type humidifier which is the basis of the former will be described with reference to FIG.
[0005]
In the figure, reference numeral 1 denotes a horizontally long box-type humidifier main body, and 2 a water tank provided at the lower part of the main body 1, which is supplied with water by a cartridge-type water supply tank 3 or the like. Reference numeral 4 denotes a humidifying drum. A cylindrical humidifying filter 5 made of urethane foam (foam) is attached to the outer periphery, one is a closed portion 6 and the other is an opening 7, and the main shaft 1 rotates around a central shaft 8. It is supported as a shaft, and the lower part of the humidifying filter 5 is immersed under the water surface of the water tank 2.
[0006]
A gear motor 9 has a drive shaft for rotating the central shaft 8 of the humidifying drum 4 and rotates the humidifying drum 4. Reference numeral 10 denotes a blower mounted in the main body 1 and blows air into the inside from the opening 7 of the humidifying drum 4 in the water tank 2. Reference numeral 11 denotes a wind direction body attached to the central shaft 8, which is formed in a conical shape so as to follow the inner diameter of the humidifying drum 4 from the point where the wind speed of the air coming out from the surface of the humidifying filter 5 is weakened to the end.
[0007]
In the operation, first, water is supplied from the water supply water tank 3 to the water tank 2, and the water in the water tank 2 is kept at a constant water level. When the humidifying drum 4 rotates inside the water tank 2, the humidifying filter 5 attached around the humidifying drum 4 is a foam, so that water droplets adhere to the empty cannon or a film is formed and contains water. Become.
[0008]
Next, when the blower 10 is driven to blow air from the opening 7 of the humidifying drum 4, the air passes through the humidifying filter 5 and is blown out to the outside.
[0009]
When air passes through the humidifying drum 4, the water droplets and film in the humidifying filter 5 are broken and no longer humidify. Therefore, the humidifying filter 5 is continuously rotated during operation, so that it always contains water and continuously. Humidified. At this time, the air blown into the humidifying drum 4 passes through the humidifying filter 5 along the wind direction body 11, and the moist air is blown out from the surface. This is discharged into the room and humidifies the room.
[0010]
On the other hand, the latter humidifier has a configuration as shown in FIG. 8, FIG. 9, FIG. 10, FIG.
[0011]
In the figure, 1 is a vertically long box-shaped main body, 2 is a water tank disposed at one side lower part of the main body 1, 16 is a water tank part disposed side by side of the water tank 2, and both are integrally formed of resin. Both are connected at the bottom to store the same level of water. And this water tank 2 and the water tank part 16 can be taken out of the main body 1 through the opening part 1a provided in the back surface of the main body 1. FIG.
[0012]
A water supply tank 3 is inserted into the main body 1 from the upper surface of the main body 1 and is placed on the water tank 2 to supply a certain amount of water into the water tank 2.
[0013]
Reference numeral 12 denotes a suction port for taking indoor dry air into the main body 1, which opens to the side surface of the main body 1. Reference numeral 13 denotes an air outlet for sending moist air into the room, which opens on the upper surface of the main body 1. Reference numeral 10 denotes a blower disposed in the air path from the suction port 12 to the blower port 13, a heater 14 for heating the wind on the discharge port side, and a sheet having good water absorption with a small hole 15 a on the entire surface. A horizontal rectangular vaporization filter 15 obtained by pleat-folding the material is disposed, and the lower end thereof is immersed in water in the water tank section 16.
[0014]
And the indoor dry air sucked from the inlet 12 by the blower 10 passes through the heater 14 and then passes through the vaporization filter 15 part wetted by the water in the water tank part 16, and the air moistened into the room from the outlet 13. Release.
[0015]
Reference numeral 17 denotes a filter case made of a frame, which covers the periphery of the vaporization filter 15 and accommodates the vaporization filter 15, and is provided with a rotation fulcrum 18 on the rear side substantially in the middle of both side surfaces. Reference numeral 19 denotes a fulcrum receiving portion for receiving the fulcrum 18, which is provided on the rear side of both side surfaces of the water tank portion 16 so as to open to the upper surfaces of the both side surfaces, and the vaporization filter 15 can be removed through the opening portions. .
[0016]
Reference numeral 20 denotes a curved rib provided on one side surface of the filter case 17, which is connected to one fulcrum 18.
[0017]
The rib 20 is engaged with a crank 21 and a crank 22 that are interlocked with the gear motor 9 attached to the partition wall of the water tank 3 for supplying water, and the vaporization filter 15 is rotated to a certain angle to rotate the vaporization filter 15. The lower part is made to come out from the water surface of the water tank part 16, and at this time, the rotation is stopped by the changeover switch 23, and in this state, warm air from the heater 14 is blown to the vaporization filter 15 to dry the vaporization filter 15. ing.
[0018]
Next, the operation will be described.
[0019]
In operating the humidifier, first, water is put into the water supply water tank 3 and installed in the water tank 2 from the upper surface of the main body 1.
[0020]
As a result, a certain amount of water also flows out from the water tank 3 for water supply into the water tank section 16 communicating with the water tank 2, fills the lower part of the vaporization filter 15 immersed in the water tank section 16, and the vaporization filter 15 sucks up water. Moisten.
[0021]
When the blower 10 is driven in this state, the dry air in the room sucked from the suction port 12 is heated by the heater 14 provided in the air passage, and the heated warm air has a lower portion in the water tank portion 16. It passes through the vaporization filter 15 dipped in water and wets, vaporizes the water in the vaporization filter 15, and is sucked into the outlet 13 and released into the room.
[0022]
After use, when the operation is stopped, the gear motor 9 is rotated, and the vaporization filter 15 is supported by the fulcrum 18 to a certain angle as shown in FIG. When the vaporization filter 15 comes out of the surface of the water, the changeover switch 23 stops the rotation of the vaporization filter 15.
[0023]
In this state, warm air is blown by the heater 14 to dry the vaporization filter 15.
[0024]
Here, the vaporization filter 15 will be described. As shown in FIG. 11, the vaporization filter 15 is formed in a horizontal rectangle obtained by pleat-folding a sheet-like material having good water absorption with a small hole 15a formed on the entire surface. The ability to suck up water is limited, and the performance is as shown in FIGS. 12A and 12B showing the relationship between the suction height H and time T, and reaches a certain height H ′. Then, it will saturate and will not absorb water.
[0025]
That is, even if the vaporization filter 15 is enlarged in the height direction, if it exceeds the suction height limit, it does not contribute to moisture vaporization, that is, humidification. For this reason, most of the conventional vaporization filters 15 are used in a horizontally long shape with a low height.
[0026]
[Problems to be solved by the invention]
The humidifying filter 5 in the former vaporizing humidifier is made by foaming urethane and submerging the humidifying filter 5 once by using the empty cannon part made by the foaming to hold water droplets in the empty cannon or making a film. By letting the wind through the state, the wind was destroying the water droplets or breaking the membrane to wet the wind. For this reason, once the wind passes, the subsequent wind passes and the humidification efficiency is poor.
[0027]
In addition, for example, when using a sheet of the filter material that is currently used with good suction performance, the air flow cannot be taken because the passage resistance is large, and the area of the humidification filter 5 is increased to obtain the same amount of humidification. There was a problem that the main body 1 would become large.
[0028]
Furthermore, since the humidification filter 5 is still submerged, mold | fungi etc. generate | occur | produced in the humidification filter 5 and there also existed a problem of causing a bad smell.
[0029]
For this reason, in recent years, as shown in the latter, a filter provided with a function of drying the vaporization filter 15 from the water surface by rotational movement has become widespread. Another advantage of this product is that it can be made into a thin product that does not take up space.
[0030]
However, the vaporization filter 15 in this latter is pleated as described above to secure a humidified area, but the thickness of the main body 1 is such that the air path from the blower 10, the vaporization filter 15, and the air outlet 13. Regulated by air path. This is because the height is restricted in consideration of the suction performance of the vaporization filter 15 as described in the above prior art, and the area of the vaporization filter 15 is reduced in the width and thickness directions in order to obtain a suitable amount of humidification. There is a need to ensure.
[0031]
Moreover, when the air path of the blower outlet 13 is too narrow, it causes a reduction in the air volume, and the amount of humidification decreases.
[0032]
Also, the air passage from the blower 10 requires an area suitable for the vaporization filter 15 similarly to the air passage of the air outlet 13. To make the main body 1 thin, the dimensions and the air passage of the vaporization filter 15 are required. Securing is the point.
[0033]
In addition, since the filter case 17 that houses the vaporization filter 15 also rotates, the filter case 17 contacts when rotating when there is no gap between the outer periphery of the filter case 17 and the outer case 10c of the blower 10 located on the upper surface thereof. If the gap is too large, the wind escapes from the gap and does not contribute to the humidification.
[0034]
In order to close the gap, it is conceivable to fix a non-woven seal sheet that can be softly sealed to the outer periphery of the filter case 17 by welding, caulking, or the like. The seal sheet and the outer case 10c come into contact with each other at the time of rotation, and abnormal noise is generated, and the seal sheet peels off with a slight force.
[0035]
[Means for Solving the Problems]
In Claim 1 of this invention, the water tank which supplies a fixed amount of water to this water tank part, the water tank for water supply, the inlet port which takes in the indoor dry air, and the blower outlet which sends the humid air indoors , Pleat fold the air blower arranged in the air passage communicating between the two ports, the heater arranged on the outlet side of the air blower, and the sheet-like material with small holes and good water absorption It is formed by a vaporization filter with the lower part immersed in water in the water tank part and a filter case that holds the periphery of this vaporization filter, and passes the dry air in the room sucked from the suction port by the blower through the heater In a humidifier that passes through a vaporization filter moistened with water in the water tank and blows out from the outlet, the vaporization filter and the filter case rotate in the vertical direction. And, and, it is provided with a sealing sheet having flexibility at the top and bottom of the filter case.
[0036]
According to a second aspect of the present invention, the filter case and the seal sheet are made of the same material.
[0037]
Further, in claim 3, the filter case and the seal sheet are made of polypropylene or polyethylene.
[0038]
As a result, by rotating the vaporization filter and alternately immersing both ends in the water in the water tank, the whole can contribute to the vaporization of moisture, that is, humidification, and the influence on the thin shape of the outlet is reduced. It is possible to make the main body thinner.
[0039]
In addition, when humidification is stopped, the vaporization filter is dried in a substantially horizontal state, making it the position farthest away from the surface of the water, making it difficult to get wet. Wetness disappears again.
[0040]
Furthermore, when the humidifier is operated, the gap between the air blower is closed by the seal sheet provided in the filter case, and the air from the air blower cannot pass through, increasing the amount of humidification.
[0041]
Furthermore, since the material of the seal sheet is the same, they are melted together at the time of heat welding, can be fixed with good adhesion, and are difficult to peel off.
[0042]
Furthermore, by using polyethylene or polypropylene in which the filter case and the seal sheet can be integrally molded, it is strong and flexible, and noise is less likely to occur even when it comes into contact with the blower.
[0043]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described below with reference to FIGS. 1 to 6 in the accompanying drawings.
[0044]
In these figures, a main body 1, a water tank 2, and a water tank 2, which are formed integrally with each other and connected at the bottom to store water of the same level, a water tank 3 for water supply, a blower 10, a heater 14, The air outlet 13 for ejecting the damp air is the same as that shown in FIG. 8, and the description thereof is omitted.
[0045]
The air inlet 12 takes indoor dry air into the main body 1 and is provided on the front and back surfaces of the main body 1 facing the motor 10a and the blades 10b of the blower 10.
[0046]
Reference numeral 15 denotes a vaporization filter, which is a pleated fold of a water-absorbing sheet-like material with a small hole formed on the entire surface, and is formed into a vertical rectangle as a whole, and its lower end is immersed in the water in the water tank 16 Has been.
[0047]
Reference numeral 17 denotes a frame-shaped filter case made of polypropylene or polyethylene, which covers the periphery of the vaporization filter 15 and accommodates the vaporization filter 15 and rotates approximately halfway between the front side and the rear side of the main body 1. A fulcrum 18 for rotation and a gear 24 for rotation are provided, and a cam 25 is provided on the gear 24.
[0048]
Reference numeral 17a denotes a sheet-like seal sheet provided on the upper and lower portions of the filter case 17 by heat welding. The sheet 17a is made of polypropylene or polyethylene having the same material as the filter case 17 and is located on the upper surface thereof. The gap between the case 10c and the filter case 17 is closed.
[0049]
Reference numeral 19 denotes a fulcrum receiving portion that receives the fulcrum 18 and is provided on one side surface of the water tank portion 16.
[0050]
A gear motor 9 is provided inside the back surface of the main body 1 facing the gear 24, and its shaft is fitted to the gear 24 through a joint 30. A timer 29 controls the gear motor 9.
[0051]
A drive shaft 28 is pivotally supported at one end. The lower surface of the front end faces the cam 25, and the substantially central portion of the upper surface faces the changeover switch 23 of the gear motor 9. When the vaporization filter 15 rotates, the vaporization filter 15 is rotated. 15 is stopped at a specified position. That is, when the vaporization filter 15 rotates and stops obliquely so that the lower end of the vaporization filter 15 is submerged in the water surface of the water tank section 16, the changeover switch 23 is opened and stopped periodically to rotate about 180 degrees.
[0052]
Further, after the vaporization filter 15 rotates and stops at a specified position, the gear motor 9 is stopped by the timer 29, is made substantially parallel to the water surface, the vaporization filter 15 is lifted from the water surface, and a drying operation is performed by the blower 10. I am doing so.
[0053]
Next, the operation will be described.
[0054]
When the humidifier is operated, water is put into the water supply water tank 3 and installed in the water tank part 16 so that a fixed amount of water flows out of the water supply water tank 3 into the water tank part 16 and fills the lower end of the vaporization filter 15. . Therefore, the vaporization filter 15 sucks up and wets the water.
[0055]
At this time, the gap between the outer case 10c of the air blower 10 and the filter case 17 is closed by the seal sheet 17a provided on the upper part of the filter case 17, and the air from the air blower 10 cannot pass through. .
[0056]
When the blower 10 is driven in such a state, the indoor dry air sucked from the suction port 12 is heated by the heater 14 provided in the air passage. Then, as shown in FIG. 6A, the heated warm air passes through the vaporization filter 15 part wetted by submerging one end in the water of the water tank part 16 and vaporizes the water in the vaporization filter 15. The air is sucked into the air outlet 13 and discharged from the air outlet 13 into the room.
[0057]
At this time, the air corresponding to the gap between the filter case 17 and the outer case 10c of the blower 10 also flows toward the vaporization filter 15 to increase the amount of humidification.
[0058]
Further, when the vaporization filter 15 is stopped so as to be slightly inclined as shown in the figure, the portion immersed in the water in the water tank portion 16 is small, and the portion exposed in the air passage is increased, and this much A lot of wind from the blower 10 hits the exposed portion, and the amount of humidification increases.
[0059]
Further, the lower end of the vaporization filter 15 is submerged in water and stopped obliquely, and at the same time, a predetermined time is counted by the timer 29. During that time, the vaporization filter 15 having good wicking properties simultaneously humidifies and sucks up water. 15 is moistened.
[0060]
Next, the vaporization filter 15 rotates approximately 180 degrees as shown in FIGS. 6A to 6C, and the timer 29 counts a predetermined time. Meanwhile, the vaporization filter 15 stops in a state where the other lower end that has not been submerged until now is submerged in water, vaporizes the water in the vaporization filter 15 and is sucked into the air outlet 13, and then enters the room from the air outlet 13. Released.
[0061]
At this time as well, the air corresponding to the gap between the filter case 17 and the outer case 10c of the blower 10 flows toward the vaporization filter 15 to increase the amount of humidification. Moreover, the humidification filter 5 is stopped diagonally and the amount of humidification is increased.
[0062]
Thereafter, this operation is repeated to continue humidification. At this time, the humidifying filter 5 may be rotated forward or backward.
[0063]
After completion of humidification, the vaporization filter 15 is rotated from the state of FIG. 6C by approximately 90 degrees as indicated by an arrow, and the whole is brought into a substantially horizontal state with the water surface of the water tank section 16 as shown in FIG. 6B. It keeps on the water surface so that it may become, and at the same time, a predetermined time is counted by the timer 29, and during that time, it is dried by the wind heated by the heater 14 provided in the air passage.
[0064]
When the water tank 2 and the water tank part 16 including the vaporizing filter 15 are removed from the main body 1 for cleaning after the humidification stop, they may be taken out from the opening 1a of the main body 1 as shown by the arrows as shown in FIG.
[0065]
In the case of the humidification, if the filter material sucks up 90 mm in the time determined by the timer 29, for example, 3 minutes, for example, from the suction performance of the vaporization filter 15, the water tank 2 is rotated by about 180 degrees once in 5 minutes. The 90 mm portion that has been wet from the inside is rotated by about 180 degrees and rotated halfway upward, and the upper filter portion that has been humidified and dried for 5 minutes is half-rotated and submerged in the water tank 2 to absorb water.
[0066]
Therefore, in the conventional vaporization filter, as shown in FIG. 12, when the vaporization filter 15 cannot be made higher than the suction height, and the performance deteriorates due to adhesion of scales or the like even in terms of life, Above the vaporization filter 15, the suction is not enough to catch up, resulting in insufficient humidification, resulting in reduced efficiency. However, the present invention can solve these drawbacks.
[0067]
Further, after the vaporization filter 15 is rotated and stopped at a specified position, the gear motor 9 is stopped by the timer 29. For example, if it takes 10 seconds for half rotation, the gear motor 9 is stopped in a time such as 5 seconds, The vaporization filter 15 is dried by energizing the heater 14 provided in the air passage, positioned substantially parallel to the water surface. At this time, since the vaporization filter 15 is located in a position substantially parallel to the farthest from the water surface, the vaporization filter 15 does not get wet even when the water surface in the water tank 2 shakes during transportation.
[0068]
Further, in the conventional product, the rib 20 and the crank 21 are detached from the state of FIG. 10 when the water tank 2 is attached and detached, and the vaporization filter 15 is wetted. However, in the present invention, the vaporization filter 15 is pulled out in a horizontal state and thus wetted with water. It is difficult to store the vaporization filter 15 as it is.
[0069]
Further, in the present invention, the sheet-like seal sheets 17a provided at the upper and lower portions of the filter case 17 block the gap between the upper part of the filter case 17 and the outer case 10c of the blower 10, so that the wind corresponding to the gap is a vaporization filter. It flows to the 15 side and increases the amount of humidification.
[0070]
Further, since the seal sheet 17a is made of a flexible material, no contact noise is generated when rotating while contacting the outer case 10c of the blower 10, and the amount of humidification is increased because rotation is not hindered. There is no obstacle to doing it.
[0071]
The seal sheet 17a may be made of polyester, polypropylene, polyethylene, non-woven fabric, etc., but polyester is too hard to generate contact sound, and is unsuitable for non-woven fabric. It becomes hard due to, etc., and is not suitable for preventing rotation or generating abnormal noise. In this respect, since the present invention uses polypropylene or polyethylene which is both flexible and flexible, the above problems are eliminated.
[0072]
Moreover, since both are made of the same material in consideration of welding the seal sheet 17a to the filter case 17, peeling can be prevented and adhesion can be improved.
[0073]
【The invention's effect】
As described above, the present invention can contribute to the vaporization of moisture, that is, humidification, by rotating the vaporization filter and alternately immersing both ends thereof in the water in the water tank section. The influence on the thin shape can be reduced, and the main body can be made thinner.
[0074]
Further, when the humidifier is operated, the seal sheets provided at the top and bottom of the filter case close the gap with the blower, and the wind from the blower cannot pass through and the amount of humidification increases.
[0075]
Furthermore, since the filter case and the seal sheet are made of the same material, they are melted together at the time of heat welding, can be fixed with good adhesion, and are difficult to peel off.
[0076]
Furthermore, the material of the filter case and the sealing sheet is made of polypropylene or polyethylene, so that it is strong, flexible, easy to mold, and does not generate abnormal noise even when it comes into contact with the blower. .
