Abstract

<P>PROBLEM TO BE SOLVED: To provide a humidifier capable of stably generating the desired amount of ions with comparatively low output. <P>SOLUTION: As a wind shielding wall 18 is mounted, wet air vaporized by a vaporization filter 2 is blocked and does not reach an electrode 14 and a counter electrode 15. Further the electrode 14 and the counter electrode 15 are placed in the atmosphere of unhumidified air by mounting a supplying part 33. Thus the negative ions can be stably generated, and its generating quantity is not reduced. The sufficient quantity of negative ions can be released to the outside with the humidified air, and the output voltage of the negative ion generator 6 can be set low. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a humidifier equipped with a negative ion function.

  Conventionally, in this type of humidifier, the mainstream is an electrothermal method in which the liquid in the evaporation tank is heated by a heater to generate steam. However, from the viewpoint of energy saving, the liquid impregnated in the vaporizing means is removed by wind. The vaporization type that obtains humid air has been reviewed, and recently, the flow is shifting to a combined type of electric heating and vaporization type.

  On the other hand, in the vaporizing humidifier, the amount of air is larger than that of the electric heating because of the provision of the blower. Taking advantage of these features, the number of models that are further equipped with a negative ion generation function is increasing due to health appeal.

A humidifier equipped with such a vaporization means generally stores liquid such as water supplied from a water supply tank in a liquid tank, absorbs the liquid in the liquid tank into a vaporization filter as vaporization means, and vaporizes the liquid. Heated air is applied to the filter to vaporize the absorbed liquid and generate humid air. In addition, as a negative ion generator, an electrode for discharging, which is an ion generation unit, is arranged in the air blowing path, and air is directly applied to the electrode, so that ions generated by the electrode, that is, negative ions, together with the blown air are exposed to the outside. What is released is known (see, for example, Patent Document 1).
JP 2001-338744 A

  However, if the negative ion generator is applied to a humidifier as it is, humidified air is directly applied to the discharge electrode, so that generation of negative ions is less than when discharged in non-humidified air. There is a problem that it becomes stable and the amount of generation is reduced. On the other hand, even in high-humidity air, if the output voltage applied to the electrode is increased, negative ions can be generated stably to some extent, and the generation amount can be increased. Has a problem of increasing the amount of harmful ozone generation, which is a by-product, because of the large amount of power consumption.

  The present invention has been made to solve such problems, and an object thereof is to provide a humidifier that can stably supply a desired amount of ions with a relatively low output.

  In the humidifier of the present invention, the moisture-proof means provided in the ion part is configured by a shielding part that prevents the wet part from being applied to the ion part and / or a supply part that supplies a dry body to the ion part. Therefore, if the shielding part is provided, the wet body vaporized by the vaporizing means is shielded without reaching the ion part, and if the supply part is provided, the ionic part is not humidified in the dry body atmosphere. Will be placed inside. Therefore, in any case, the supply of ions does not become unstable, and the supply amount does not decrease. Thus, a sufficient amount of ions can be released to the outside together with the wet body.

  According to the present invention, since the wet body does not directly hit the ion portion, even if the output of the ion portion is set low, the supply of ions does not become unstable and the supply amount does not decrease. Therefore, ozone, which is a by-product, can be suppressed and power consumption can be reduced.

  Hereinafter, an embodiment of a humidifier according to the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a cross-sectional view of the humidifier of the present embodiment, and FIG. 2 is a cross-sectional view of the humidifier cut in a direction perpendicular to the cutting direction of FIG.

  As shown in the figure, the humidifier 1 of the present embodiment includes a vaporization filter 2 as vaporization means for vaporizing water as a liquid, a water tank 3 as a liquid tank for supplying water to the vaporization filter 2, and the water tank 3. A water supply tank 4 as a liquid reservoir for supplying water, a blower 5 for blowing air to the vaporization filter 2, and a negative ion generator 6 disposed in a blower path 31 on the downstream side of the vaporization filter 2 are provided. The vaporization filter 2, the water tank 3, the water supply tank 4, the blower 5 and the negative ion generator 6 are accommodated in the outer shell 7 of the humidifier 1 constituted by the outer shell front portion 7a and the outer shell rear portion 7b. . In addition, the humidifier 1 of this embodiment is also provided with the heater 8 which is a ventilation heating means for heating the wind sent with the air blower 5. FIG.

  Next, each part will be described in detail. The vaporization filter 2 of the present embodiment is disposed at the lower part of the humidifier 1 and is formed by folding a filter cloth made of a material having excellent hygroscopicity (for example, cloth) into a pleat shape. . In addition, the cloth of the vaporization filter 2 can be given antibacterial performance by sewing (not shown) with a wire material in which copper is partially silver-plated, for example.

  A water tank 3 is disposed below the vaporization filter 2, and the lower part of the vaporization filter 2 is immersed when a predetermined amount of water is put into the water tank 3. In addition, a detachable water supply tank 4 is disposed at one end of the water tank 3 with a water supply cap 9 facing down, so that the water level of the water tank 3 is always kept constant. In addition, you may provide the antibacterial means 10 which put and formed the copper fiber in the bag-shaped nonwoven fabric between the water supply tank 4 and the vaporization filter 2, for example.

  The blower 5 for sending air to the vaporization filter 2 is composed of a fan main body 11 such as a sirocco fan and a motor 12 that is a rotational drive source of the fan main body 11. Further, an air inlet 13 is formed in the outer front part 7 a facing the fan body 11. Air is taken in from the air inlet 13, and the air flow path 32 on the upstream side of the vaporization filter 2 below the air blower 5. It arrange | positions so that it may ventilate.

  The heater 8 is provided in the ventilation path 32 between the blower 5 and the vaporization filter 2, and includes, for example, a heating wire 8a. The heating wire 8a is energized and heated, and passes through the vicinity of the heating wire 8a. It heats the air.

  As shown in FIG. 3, the negative ion generator 6 includes an ion generator including a needle-like electrode 14 with a sharp tip and a plate-like counter electrode 15 facing the electrode 14, and the rear of the blower 5 is provided. The cover 16 is attached slightly above the rear wall 16a of the cover 16. Between the electrode 14 and the counter electrode 15 on the rear wall 16a, dry air is applied to the electrode 14 and the counter electrode 15 as moisture-proof means for preventing the humid air from directly touching the electrode 14 and the counter electrode 15 of the negative ion generator 6. Is provided with a rectangular opening 17 for direct feeding. A windshield wall 18 projecting further rearward from the rear wall 16a is similarly attached as a moisture-proof means to the lower portion of the rear wall 16a. The wind shield wall 18 is provided as a wind shield portion that shields the humid air flowing through the air passage 31 from the electrode 14 and the counter electrode 15, and is formed by bending one end of the rectangular plate in the longitudinal direction at a right angle, and then bending it. The rear portion 16a is attached to the rear wall 16a with the other portion 18a vertical and the other portion 18b horizontal.

  Reference numeral 19 denotes a partition plate for partitioning the inner space of the outer frame into a housing part 19a for the water supply tank 4 and a fluid part 19b for generating an air flow. Moreover, the front wall 16b of the cover 16 provided in the rear part of the air blower 5 is provided with a hole 20 through which a part of the wind generated by the air blower 5 flows, and the air blower 5, the hole 20, and the opening. 17 constitutes a dry air supply section 33 that guides air that is not damp to the electrode 14 and the counter electrode 15. Furthermore, a vent hole 21 that leads to the outside of the humidifier 1 is provided in the upper portion of the outer shell 7.

  Next, the effect | action is demonstrated about the said structure. First, water W is put into the water supply tank 4 and the water supply tank 4 is installed in an inverted state on one side of the water tank 3. Then, the water W in the water supply tank 4 flows out from the water supply cap 9, stops the outflow by setting the water tank 3 to a constant water level.

  The lower part of the vaporization filter 2 is immersed in the water in the water tank 3, and the filter fabric sucks up the water W. When the water W in the water tank 3 is sucked up by the vaporization filter 2 and its water level is lowered, it is supplied from the water supply tank to a predetermined water level, and a constant water level is always maintained.

  Thus, after the water vapor W has been absorbed by the vaporization filter 2, when the operation switch (not shown) of the operation display panel is turned on, the motor 12 is activated and the fan 11 starts rotating, and the heater 8 8a is heated. The rotation of the fan 11 causes air to be taken into the outer shell 7 from the air inlet 13, and the taken-in wind is released in the direction of the lower heater 8, passes through the hot wire 8 a, is heated, and is vaporized filter 2. The vaporization filter 2 hits from the upstream air flow path 32. As a result, the water W absorbed in the vaporization filter 2 is vaporized, and this time becomes humidified air and rises inside the outer rear wall 7b of the humidifier 1 along the air passage 31 on the downstream side of the vaporization filter 2 ( (See arrow in FIG. 1). When the humidified air passing through the blower passage 31 reaches the lower part of the negative ion generator 6, the humidified air hits the wind shielding wall 18, and does not hit the electrode 14 and the counter electrode 15, which are ion generators, and enters the vent hole 21. It will flow.

  On the other hand, a part of the wind generated by the fan 11 does not pass through the heater 8 and the vaporization filter 2, passes through the hole 20 provided in the front wall 16 b of the cover 16 behind the fan 11, and opens behind the cover 16. It flows to part 17. The non-humid air that has passed through the opening 17 flows between the electrode 14 and the counter electrode 15 of the negative ion generator 6, merges with the humidified air that passes through the air passage 31, and enters the vent hole 21 together with the humidified air. It will flow.

  Here, when a corresponding switch (not shown) of the operation display panel is turned on to supply negative ions into the room, a high voltage is applied between the electrode 14 and the counter electrode 15 of the negative ion generator 6, Negative ions are generated. In this case, since the periphery of the electrode 14 and the counter electrode 15 of the negative ion generator 6 is filled with dry air having the same humidity as the outside air that has not passed through the vaporization filter 2, a stable amount from the negative ion generator 6 is obtained. Negative ions are generated. The dry air containing negative ions merges with the humidified air that has passed through the vaporization filter 2 and is discharged to the outside from an exhaust port 21 provided above the outer shell 7.

  As described above, according to the above-described embodiment, the vaporization filter 2 as a vaporizing means for vaporizing the liquid, the blower device 5 that applies wind to the vaporization filter 2, and the blower path 31 that is a path downstream of the vaporization filter 2. In the humidifier 1 provided with the electrode 14 and the counter electrode 15 as the arranged ion part, the wind shielding wall 18 as a shielding part for preventing the electrode 14 and the counter electrode 15 from being exposed to wet air as a wet body, and the electrode 14 Further, the electrode 14 and the counter electrode 15 are provided with moisture-proof means including either or both of the supply unit 33 that supplies dry air as a dry body to the counter electrode 15.

  According to this, if the wind shielding wall 18 is provided, the humid air vaporized by the vaporization filter 2 is blocked without reaching the electrode 14 and the counter electrode 15, and if the supply unit 33 is provided, the electrode 14 The counter electrode 15 is placed in an atmosphere of unhumidified air. Therefore, in any case, generation or supply of negative ions does not become unstable, and the generation amount thereof does not decrease. In this way, a sufficient amount of negative ions can be released together with the humidified air, the output voltage of the negative ion generator 6 can be set low, ozone generation as a byproduct can be suppressed, and power consumption can be reduced. Can be suppressed.

  Further, in the present embodiment, since both the wind shielding wall 18 and the supply unit 33 are provided, the periphery of the electrode 14 and the counter electrode 15 is filled with dry air guided by the supply unit 33, which is further minus. Ions can be released efficiently.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation is possible. For example, the humidifier may be applied not only to the vaporization type described above but also to a steam type that performs humidification with steam obtained by heating a liquid.

It is a one-way longitudinal cross-sectional view of a humidifier in a preferred embodiment of the present invention. FIG. 2 is a longitudinal sectional view in the direction perpendicular to FIG. The same as above, (a) is a front view of the negative ion generator, and (b) is a side sectional view of the negative ion generator.
