BACKGROUND OF THE INVENTION
The present invention relates to a vaporizing humidifier.
[0002]
[Prior art]
In the conventional vaporizing humidifier, the vaporizing element is wetted with water and humidified by applying the wind generated by the blower fan to it, and various germs and molds adhere to the vaporizing element. In some cases, there was a problem of breeding. For this reason, it is necessary to disinfect the vaporizing element by applying hot water or the like.
[0003]
Therefore, conventionally, a vaporizing humidifier as shown in FIG. 6 has been proposed.
In FIG. 6, 1 is a main body of the humidifying device, 2 is a water tank provided in the lower part of the main body 1, and 3 is a vaporizing element having water absorption disposed so that the lower part is immersed in the water in the water tank 2. Is a heater for heating the water in the water tank 2, 5 is a water tank, 6 is a blower fan, 7 is a suction port, and 8 is a discharge port.
In the conventional vaporizing humidifier shown in FIG. 6, after confirming that there is water in the water tank 2, by turning on the operation switch (not shown), the blower fan 6 is rotated and the suction port 7 is turned on. Outside air is sucked in, passes through the vaporizing element 3 and is discharged to the outside through the discharge port 8. At this time, the vaporizing element 3 sucks up the water in the water tank 2 due to its water absorption and is wet with water, so the air passing through the vaporizing element 3 is humidified and humidifies the room.
Further, when the vaporizing element 3 was sterilized, the vaporizing element 3 was sterilized by energizing the heater 4 and heating the water in the water tank 2. As shown in FIG. 7, the vaporizing element has a plurality of rectangular humidifying elements 3a made of polyester nonwoven fabric and a pair of holders for laminating the humidifying elements 3a at a predetermined pitch. 3b and a fixture 3c for fixing the pair of holders 3b.
[0004]
[Problems to be solved by the invention]
In the case of the conventional vaporizing humidifier, the lower part of the vaporizing element 3 is simply immersed in hot water, and the hot water is sucked up and sterilized. It took time to reach, and it was difficult to disinfect the entire vaporizing element 3 because the temperature of the hot water was lower than the temperature at which it could be sterilized, or the hot water did not reach the top. . Further, since the vaporizing element 3 is only for sucking hot water from the lower part, the humidifying element 3a is held at the upper part and the lower part by the holder 3b, but the intermediate part is not held anywhere, so it is strong. However, when water or hot water is applied from the side or from above, the shape collapses and the humidifying element 3a is detached from the holder 3b.

Reference numeral 13 denotes a water channel for allowing the water tank 2 and the tank receiving portion 14 to communicate with each other.
[0010]
As shown in FIGS. 1 and 3, the vaporization element 3 includes a vaporization filter 15 bent in a wave shape, a comb-like member 16 holding the vaporization filter 15 bent in a wave shape at equal intervals, and a wave shape. A base frame 17 having a folding mountain support plate 17a for setting the bent vaporization filter 15 and two subs sandwiching and fixing the vaporization filter 15 bent in a wave shape via the base frame 17 and the comb-like member 16 It consists of a frame 18. The vaporizing filter 15 is made of a rayon impregnated with an acrylic resin and has water absorption. The comb-shaped member 16, the base frame 17, and the subframe 18 are formed by integral molding of synthetic resin.
[0011]
Here, as shown in FIG. 4, the base frame 17 has a pair of locking holes 17c formed in two upper and lower portions in the frame plate 17b on both sides, while the subframe 18 has a frame on both sides. A pair of locking claws 18b are formed on the plate 18a, and a plurality of pressing pieces 18c are formed at a predetermined interval.
[0012]
When assembling the vaporizing element 3, first, the comb-like member 16 is attached to the vaporizing filter 15 bent in a wave shape so as to hold the folded mountain portions at equal intervals, and this is set on the base frame 17. Then, a pair of claw portions 18a respectively formed on the frame plates 18a of the two sub frames 18 are formed on the frame plate 17b of the base frame 17 so that the vaporization filter 15 and the comb-like member 16 are sandwiched between the base frames 17. The pair of locking holes 17c are engaged and fixed. At this time, the pressing piece 18 c formed on the sub-frame 18 presses the comb-shaped member 16 against the vaporization filter 15 side.
[0013]
Next, the operation of the first embodiment of the present invention having the above configuration will be described.
First, during normal humidification operation, the heater 4 is not energized, and only the blower fan 6 and the pumping pump 10 are energized. As a result, room temperature water in the water tank 2 is pumped up by the pumping pump 10 and guided to the shower port 12 through the water pipe 11. Then, the water led to the shower port 12 is dispersed and uniformly supplied to the upper part of the vaporizing element 3, and the water supplied to the upper part of the vaporizing element 3 permeates from the upper part of the vaporizing element 3 toward the lower part. Then, it flows down, penetrates the entire vaporizing element 3, and the excessively supplied water drops from the lower part of the vaporizing element 3 and returns to the water tank 2. On the other hand, the dry air in the room is sucked from the suction port 7 by the operation of the blower fan 6, and the dry air passes through the vaporized element 3 that has absorbed the water and is dampened and discharged from the discharge port 8 to the outside. Thus, humidification is performed.
[0014]
Further, during the sterilization operation, the air blowing fan 6 is not energized, and only the heater 4 and the pumping pump 10 are energized. As a result, the heater 4 heats the water in the water tank 2 to become hot water having a predetermined temperature (for example, 80 ° C.) set in advance, and the hot water is pumped by the pump 10 and passes through the water pipe 11 to the shower port 12. Led to. The hot water guided to the shower port 12 is dispersed by the shower port 12 and supplied uniformly to the upper part of the vaporizing element 3, and the hot water supplied to the upper part of the vaporizing element 3 is supplied from the upper part of the vaporizing element 3. After flowing down toward the lower part and permeating the vaporizing element 3 without breaking down, the hot water supplied excessively dropped from the lower part of the vaporizing element 3 and returned to the water tank 2, The hot water that has returned to 2 is heated again to a predetermined temperature, pumped by the pump 10, and supplied to the water pipe 11, the shower port 12, and the vaporizing element 3. This operation is repeated until the sterilization operation is completed.
[0015]
Here, during the humidification operation and the sterilization operation, water or hot water is supplied to the vaporizing element 3 from above, so that a plurality of rectangular humidification elements 3a as shown in FIG. Since it does not have intensity | strength in what is hold | maintained in shape with the holder 3b etc., it cannot be used. Therefore, as shown in FIG. 5, the vaporization filter 15 made of a nonwoven fabric is bent into a wave shape and is connected with a resin adhesive 19 so as to keep the intervals between the folds at equal intervals. Since the shape of the vaporization filter 15 itself can be maintained to some extent, it can be used for the time being.
However, even in the configuration shown in FIG. 5, the shape retention of the vaporization filter 15 depends on the strength of the vaporization filter 15 itself and the adhesive 19 in a state immersed in hot water. There is a concern that it will collapse and stable humidification and thermal sterilization of the entire vaporizing element 3 will not be possible.
[0016]
However, in the first embodiment, as shown in FIGS. 1 and 3, the vaporizing element 3 is formed by separating the vaporization filter 15 bent in a wave shape having water absorption and the vaporization filter 15 bent in a wave shape at equal intervals. And a base frame 17 having a folded mountain support plate 17a for setting the vaporization filter 15 folded in a wave shape, and the base frame 17 and the comb-shaped member 16 are folded in a wave shape. Since the vaporization filter 15 is sandwiched between and fixed to the subframe 18, the vaporization filter 15 is folded in a wave shape by the folding mountain support plate 17 a of the base frame 17 and the comb-shaped member 16. The ridge is securely held in shape.
[0017]
Further, a pair of claw portions 18 a formed on the frame plate 18 a of the frame 18 so as to sandwich the vaporization filter 15 and the comb-like member 16 between the base frame 17 and a pair of locking holes 17 c formed on the frame plate 17 b of the base frame 17. Since it is engaged and fixed, the frames can be fixed securely. Further, the pressing piece 18c formed on the sub-frame 18 presses the comb-shaped member 16 against the vaporization filter 15 side, so that the comb-shaped member 16 is prevented from coming out and the position is shifted up and down, and the vaporization filter at the time of heat sterilization The shape retention of 15 can be further ensured.
[0018]
In the first embodiment, the comb-like member 16 and the vaporization filter 15 are configured as separate bodies. However, the comb-like member 16 is bent together with the vaporization filter 15 at the same time and fixed to the following filter 15 together. Good. In this case, since the comb-shaped member 16 is fixed integrally with the vaporization filter 15, the position of the comb-shaped member 16 is not shifted in the vertical direction, the shape of the vaporization filter 15 can be maintained more reliably, and assembly can be performed. It becomes easy. Further, although two subframes 18 are provided, a single subframe 18 may be configured.
[0019]
【The invention's effect】
As described above, according to the present invention, even if hot water is supplied to the vaporizing element from above, there is no fear that the shape of the vaporizing filter will collapse, so stable humidification and the entire vaporizing element can be heated uniformly. A vaporizing humidifier that can be sterilized can be obtained.
[0020]
Further, since the comb-like member is fixed integrally with the vaporization filter, the position of the comb-like member is not displaced in the vertical direction, and the shape of the vaporization filter can be more reliably maintained and the assembly is facilitated.
[0021]
Furthermore, by providing the subframe with a plurality of pressing pieces that press the comb-shaped member against the vaporizing filter side at predetermined intervals, the comb-shaped member can be prevented from coming out and shifting, and the shape of the vaporizing filter can be more reliably maintained. .
