Description

  The present invention relates to a bathroom ventilation dryer that is equipped with an electrostatic atomizer and makes it difficult for mold to grow in the bathroom.

In recent years, with the increase in the number of bathroom ventilators installed in general households, the bathroom has a drying function to dry laundry, and the interior of the bathroom can be heated to alleviate heat shock in winter. Bathroom ventilation dryers that can be used are becoming popular. In addition, the Building Standards Law has been revised, and in newly built houses, it is required to install a ventilation device that has a function of constant ventilation, and this type of bathroom ventilation dryer is becoming increasingly popular.
Until now, many of these types of bathroom ventilation dryers were mainly used for ventilation, drying and heating functions. However, there are cases where the installation location is a bathroom where high humidity conditions continue for a long time, mold tends to grow inevitably, and it is often disturbed by irritating odors such as various detergents used when removing mold In addition, there is a strong demand for the bathroom ventilation dryer to make it difficult to grow mold in the bathroom, and recently, products that generate discharge-type positive and negative ions have been developed (see, for example, Patent Document 1).
JP 2004-211961 A

However, the conventional bathroom ventilation dryer has the following problems.
The life of discharge-type positive and negative ions is a problem, and generally the time of the effect of suppressing mold is short, and even if discharge-type positive and negative ions are generated, they will disappear without being able to bind to mold and other floating bacteria. There is.
In addition, because of the discharge type, there is a problem that the way of discharge and the amount of discharge change depending on environmental conditions, and positive and negative ions are hardly generated stably.

  An object of the present invention is to supply stable fine water negative ions into a bathroom.

The bathroom ventilation dryer of the present invention according to claim 1 is provided with a suction port and a blowout port in the louver at the lower part of the main body, a fan and a motor for sucking air in the bathroom are provided on the downstream side of the suction port, A bathroom ventilation dryer provided with an exhaust air passage communicating from the suction port to the exhaust adapter and a circulation air passage communicating from the suction port to the blowout port, and electrostatic atomization in the circulation air passage A bypass circulation air passage that does not pass through the heat source heater is provided as the circulation air passage, the electrostatic atomizer is provided in the bypass circulation air passage, and upstream of the electrostatic atomization device. A wall is provided in the vicinity of the side .
By this means, fine water negative ions using water molecules are generated from the electrostatic atomizer and combined with floating mold to remove floating mold, the outside of the ions are water molecules. Because it is wrapped, the action lasts longer, so it becomes more likely to bind to floating mold. Further, as described above, since the outside of the ion is wrapped with water molecules, it can also bind to odor components and the like, decompose the odor components, and soften the odor.
Further, fine water negative ions can be stably generated. In addition, since the circulation air passage is different from the warm air passage, the influence of the warm air on the fine water negative ions is small.
Further, by this means, fine water negative ions can be stably generated as described above. This is because, when a wind having a high wind speed is directly applied to the generating portion, it does not become sufficiently fine due to static electricity and is released, so that it is not stable as fine water negative ions.

  According to the present invention, it is possible to provide a bathroom ventilation dryer that can surely reduce floating mold, hardly generate mold, and can create a bathroom space with reduced smell.

The bathroom ventilation dryer according to the first embodiment of the present invention is provided with a suction port and a blowout port in the lower louver of the main body, a fan and a motor for sucking air in the bathroom are provided on the downstream side of the suction port, An exhaust air passage that communicates with the adapter and a circulation air passage that circulates in the bathroom are provided. An electrostatic atomizer and a heat source heater are provided in the circulation air passage, and the generation part of the electrostatic atomizer is sucked from the heat source heater. Provided in the bypass circulation air passage that is branched on the side and communicated to the outlet, provided as a circulation air passage is a bypass circulation air passage that does not pass through the heat source heater, and an electrostatic atomizer is provided in the bypass circulation air passage. A wall is provided in the vicinity of the upstream side of the converter. The reason why the negative ion generator is an electrostatic atomizer is that water ions are wrapped around the outside of the ions, and the action as negative ions can be continued for a long time. According to the present embodiment, it is possible to remove mold floating in the bathroom and create a bathroom space in which mold does not easily occur. In addition, odors are also characterized in that negative ions bind to odor components and are taken into water molecules enclosing the odor components, thereby reducing the odor. In addition, fine water negative ions can be stably generated, and a bathroom space similar to that described above can be created. In addition, the wind that passes through the electrostatic atomizer is not warmed by the heat source heater, but is close to the suction temperature from the bathroom. Fine water negative ions can be released. Further, since the wall is shielded so that the wind is not directly applied to the generating portion, fine water negative ions can be generated without being influenced by the wind.
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(Embodiment 1)

FIG. 1 is a configuration diagram showing a bathroom ventilation dryer according to Embodiment 1 of the present invention.
2 and 3 are configuration diagrams of damper positions for heating and ventilation, respectively.
A louver 1 at the lower part of the main body is provided with a suction port 2 and a blow-out port 3, and air in the bathroom is sucked from the suction port 2 using a fan 4 and a motor (not shown) that drives the fan 4 as indicated by an arrow a. When exhausting air sucked from the bathroom by the damper 5 and simultaneously circulating, so-called drying and cool air are performed, the damper 5 uses a damper motor (not shown) centering on the damper shaft 6 as shown in FIG. The air sucked from the bathroom is transported to the exhaust air passage 7 and the circulation air passage 8 at the same time, and a certain amount is discharged to the outside through a duct (not shown) attached to the exhaust adapter 9, and the rest is discharged. It discharges from the electrostatic atomizer 10 as fine water negative ions (so-called nano-sized negative ion mist). Then, the fine water negative ions are combined with the floating fungus, and the fungus is wrapped in the fine water and heated (dried) by the heat source heater 11 (when the cool air is generated, the heat source heater 11 is stopped). As warm air, it is blown out again into the bathroom from the outlet 3. As the heat source heater here, a ceramic heater that generates heat by electricity, a radiant halogen heater, and a carbon lamp heater can obtain the same effect, and FIG. 1 shows a ceramic heater as an example. The wind blown out at this time includes those in which mold fungi are wrapped in fine water, and these quickly adhere to the floor surface, so that floating fungi can be reduced. Therefore, mold can be made difficult to grow. Fine water negative ions can also bind to odor components contained in the air in the bathroom, wrap the odor components, and soften the odor.

In addition, when exhausting air sucked from the bathroom, or when performing so-called ventilation, the damper 5 is rotated around the damper shaft 6 using a damper motor (not shown) as shown in FIG. The sucked air is conveyed to the exhaust air passage 7 as indicated by an arrow b and discharged to the outside through a duct (not shown) attached to the exhaust adapter 9.
Further, when the air sucked from the bathroom is circulated in the bathroom, that is, when heating the so-called bathroom, the damper 5 is rotated using a damper motor (not shown) around the damper shaft 6 as shown in FIG. The air sucked from the bathroom is transported to the circulation air path 8 as indicated by arrow c, heated by the heat source heater 11 and blown out again from the outlet 3 into the bathroom as warm air, and the cold in the bathroom is alleviated. be able to.

As shown in FIG. 4, in order to release fine water negative ions released by the electrostatic atomizer 10 by circulating air into the bathroom, it is necessary to flow wind to the generator 16 of the electrostatic atomizer 10. In the present invention, a bypass air passage 17 different from the air passage communicating with the heat source heater 11 is provided from the circulation air passage 8 upstream of the heat source heater 11, and the electrostatic atomizer 10 is provided in the bypass air passage 17. Provided. For this reason, the wind passing through the electrostatic atomizer 10 is not the wind warmed by the heat source heater 11, but is a wind temperature close to the suction temperature from the bathroom. , Stable release of fine water negative ions.

FIG. 6 is a dimension diagram of the shielding wall and the opening.
A shielding wall 22 is provided in the vicinity of the upstream side of the generating unit 16 of the electrostatic atomizer 10 so that wind with a high wind speed does not directly hit the generating unit 16. The shielding wall 22 has a size of 25 mm × 70 mm that can reliably shield the generating unit 16, and the wind speed of the generating unit 16 is 0.1 m / s or less. However, since fine water negative ions released from the generator 16 are released into the bathroom, the wind speed passing through the bypass air passage 17 is 0.1 to 0.5 m / s around the shielding wall 22. The opening area of the opening 23 is adjusted.

  Since the bathroom ventilation dryer of the present invention generates a stable amount of fine water negative ions and reduces floating mold, it is possible to create a bathroom space in which mold is hardly generated and smell is suppressed.
