Description

  The present invention relates to a vaporizing humidifier.

  Conventionally, as a humidifier, an ultrasonic type that discharges water in a mist form by ultrasonic waves, a heating type that heats and evaporates water, and water absorbed by a water-absorbing filter are vaporized. The vaporization method to be used was used.

Ultrasonic and heating systems have a relatively small device and a large amount of humidification can be obtained, but the ultrasonic system has the problem of lack of hygiene because impurities in the water are released into the air together with water. The heating method has a problem that power consumption for heating is large and lacks energy saving.
On the other hand, the humidifier of the vaporization system passes the air through the filter or flows the air along the filter to vaporize the water held by the filter, that is, naturally evaporate, so that the humidification is performed, so that impurities are released into the air. Without excessive humidity, the power consumption of a blower such as a fan is small, and hygienic, humidifying, and energy saving are excellent.
There exists a thing shown in patent document 1 as such a vaporization type humidifier. The humidifier of Patent Document 1 is provided with a water supply unit that supplies water and a vaporizing member that releases water supplied from the water supply unit to the ventilation space as water vapor, and emits ultraviolet rays to the vaporizing member. It has a configuration in which an ultraviolet lamp for irradiation is provided.

When the water level flowing down to the water reservoir 19 reaches the height of the water supply port 16b, air cannot flow into the water storage tank 16, and the water outflow from the water supply port 16b is stopped. Is maintained at the height of the water supply port 16b.
Next, when the water supply pump 21 is driven, the water in the water reservoir 19 is supplied to the water reservoir 7 through the water supply pipe 20. When the water level stored in the water storage section 7 reaches a predetermined water level, the water level detector 24 is activated and the drive of the water supply pump 21 is stopped. In this way, the water level of the water storage unit 7 is always maintained at a predetermined water level during the humidifying operation.
In addition, since the water reservoir 19 is disposed at a position lower than the water reservoir 7, when the humidifying operation is not performed (when the blower 5 is stopped, etc.), the open / close valve 23 is opened and the water in the water reservoir 7 is drained. The water can be allowed to flow down to the water reservoir 19 through the reflux pipe 22, and the water storage section 7 can be emptied to keep the vaporization filter section 12 in a dry state.

A plurality of support columns 28, 28 are annular upper water reservoirs supported above the base 3 a via the support columns 25, and the tip of the upper filter extension 26 is inserted. . Reference numeral 29 denotes a water level detector disposed in the upper water reservoir 28, and 30 denotes a water supply pipe connected from the bottom of the water reservoir 19 to the upper water reservoir 28 via the water supply pump 21.

With respect to the humidifier 1b according to the third embodiment configured as described above, the infiltration operation of the vaporizing filter unit will be described below with reference to FIG. The other humidification operations are the same as those described in the first embodiment, and a description thereof will be omitted.
First, the water in the water storage tank 16 is stored in the water reservoir 19 as in the second embodiment. When the water supply pump 21 is driven, the water in the water reservoir 19 is supplied to the upper water reservoir 28 via the water supply pipe 30. When the water level stored in the upper water reservoir 28 reaches a predetermined water level, the water level detector 29 is activated and the drive of the water supply pump 21 is stopped. In this way, the water level of the upper water reservoir 28 is always maintained at a predetermined water level during the humidifying operation.
Next, when the tip end of the upper end filter extending portion 26 is inserted into the upper water storage portion 28 and immersed in the water W, the upper end filter extending portion 26 absorbs the water W and lowers from the upper end side of the vaporizing filter portion 12 to the lower end. The water W gradually infiltrates the part side. At this time, gravity acts on the water W absorbed by the vaporizing filter unit 12 together with the water absorbing action of the vaporizing filter unit 12, so that the water W rapidly infiltrates from the upper end to the lower end of the vaporizing filter 12. The water W exuded from the lower end flows down to the water reservoir 19 through the water reservoir 7 and the water reflux pipe 22.

  Here, a plurality of convex portions may be formed on the outer peripheral portion of the cover portion 13 at equal intervals of, for example, a central angle of 60 °. As a result, even if the bent portion between the vaporizing filter portion 12 and the upper filter extending portion 26 is pressed by the outer peripheral portion of the cover portion 13, the water W infiltrates through the concave portions formed between the convex portions. Therefore, the amount of water supplied to the vaporizing filter unit 12 can be maintained.

  As described above, since the humidifier according to the third embodiment is configured, in addition to the operation of the first or second embodiment, the distal end portion of the upper end filter extending portion 20 is inserted into the upper water storage portion 16 and stored. Since it is immersed in the water W, the vaporizing filter unit 12 can absorb water through the upper filter extending portion 20, and the water absorbed in the vaporizing filter unit 12 contains the vaporizing filter unit 12. Since gravity acts together with the water absorption action, the vaporization filter unit 12 can be rapidly infiltrated and the humidification efficiency can be increased.

The water supply unit 40 is formed by drilling water supply holes 40a having an inner diameter of about 1 to 5 mm at predetermined intervals in a flexible pipe formed of a synthetic resin or the like, and is annularly formed along the frame body unit 11. It is fixed by bonding or binding.

  The humidifier according to the fourth embodiment configured as described above is different from the third embodiment in that the humidifier is provided with a water supply unit 40 formed of an annular tube instead of the upper water storage unit 28 (see FIG. 5). It is a point. Due to this difference, in addition to the operation of the third embodiment, a synthetic resin pipe or the like can be used as the water supply unit 40, so that the structure can be simplified and the number of parts can be reduced, and the productivity and maintenance are excellent. Has an effect.

  As described above, the present invention relates to a vaporizer-type humidifier, and in particular, according to the present invention, the vaporizing member has a large ventilation area and excellent humidification efficiency, and it is easy to clean and maintain a filter, a main body and the like and is hygienic. It is possible to provide a humidifier that is excellent and has a high degree of freedom in design and an excellent appearance.
