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. Because of this, bathroom ventilation dryers 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 equipment were mainly used for ventilation, drying, and heating functions. However, the installation location is sometimes called a bathroom, and the bathroom is in an environment where high humidity conditions continue for a long time. It is easy to grow mold, and when using various detergents when removing mold, there is often a sense of irritating odor, etc., and it has a strong function to make mold difficult to grow in the bathroom. 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. Generally, the effect of suppressing mold is short, and there is a problem that it disappears without being able to bind to floating bacteria such as mold even though it is generated with great effort. .

  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 solve the above-described problems.

  In order to achieve the above object, the bathroom ventilation dryer of the present invention is provided with a suction port and a blowout port in the louver at the bottom of the main body, and a fan and a motor for sucking air in the bathroom are provided on the downstream side from the suction port, An exhaust air passage that communicates with the exhaust adapter and a circulation air passage that circulates in the bathroom are provided, and an electrostatic atomizer and a heat source heater are provided in the circulation air passage.

  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 outer side of the ions is encased in water molecules, it can also bind to odor components and the like, decompose the odor components, and soften the odor.

  Another means is that the heat dissipating fin portion of the electrostatic atomizer is provided in the exhaust air passage, and the generating portion of the electrostatic atomizer is provided in the vicinity of the outlet.

  By this means, fine water negative ions can be stably generated, and by providing an electrostatic atomizer near the outlet, more fine water negative ions can be released into the bathroom.

  Another means is provided in a bypass circulation air passage in which the generating portion of the electrostatic atomizer is branched from the heat source heater on the suction side and communicated to the outlet.

  By this means, fine water negative ions can be stably generated as described above. 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.

  Another means is provided with a unit in which an electrostatic atomizer and a drive control circuit of the electrostatic atomizer are integrated.

  By this means, it is possible to easily incorporate the electrostatic atomizer into the main body. Furthermore, even if the replacement is required in the market, it can be replaced in units, so that the replacement time can be shortened.

  The other means is provided so that the generating part of the electrostatic atomizer is directed downward.

  By this means, fine water negative ions can be generated very easily.

  This is because the generation part faces downward and the water molecules tend to become fine due to the combined weight and electrostatic attraction of water molecules.

  The other means operates in an operation mode for drying the electrostatic atomizer for a certain period of time before the operation of the electrostatic atomizer.

  By this means, fine water negative ions can be stably generated as described above. This is because when the electrostatic atomizer is operated in a dewed condition under high humidity conditions in the bathroom, the discharge action does not work due to the dew condensation.

  The other means operates in an operation mode in which the amount of air flowing through the bypass circulation air passage provided with the electrostatic atomizer is increased for a certain period of time before the operation of the electrostatic atomizer.

  By this means, the fine water negative ions of the electrostatic atomizer can be stably generated as described above. This is to remove foreign substances that may be attached to the discharge part of the electrostatic atomizer and appropriately perform the discharge action.

  Another means is provided with a detecting means for detecting fine water negative ions in the vicinity of the outlet, and a control means for controlling the amount of blown air.

  By this means, the amount of fine water negative ions from the main body can be kept constant.

  In order to achieve the above object, the bathroom ventilation dryer of the present invention is characterized by providing an electrostatic atomizer that stably generates fine water negative ions.

  By this means, it is possible to create a bathroom space in which floating mold is reduced, mold is hardly generated, and smell is reduced.

  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.

Bath room ventilation dryer of the present invention, the inlet and air outlet to the lower body of the louver is provided, disposed downstream from the fan and opening a suction motor for sucking air in the bathroom, to communicate to an exhaust adapter exhaust An air passage and a circulation air passage that circulates in the bathroom are provided, and an electrostatic atomizer and a heat source heater are provided in the circulation air passage. Here, the negative ion generator is an electrostatic atomizer, which is characterized by the fact that water ions wrap around the outside of the ions and can continue to function as negative ions for a long time.

  By this means, 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 by binding to odor components and taking them into the water molecules enclosing the odor components, thereby reducing the odor.

Further , the heat dissipating fin portion of the electrostatic atomizer is provided in the exhaust air passage, and the generating portion of the electrostatic atomizer is provided in the vicinity of the outlet.

  By this means, fine water negative ions can be stably generated, more fine water negative ions can be supplied in the bathroom, and mold floating in the bathroom can be removed, and the bathroom space in which mold does not easily occur is created. Can be produced.

In addition , the generating unit of the electrostatic atomizer is provided in a bypass circulation air passage that branches from the heat source heater on the suction side and communicates with the outlet.

  The circulation air passage is made into two air passages, and the air passage is unique to the electrostatic atomizer separately from the conventional heating air passage.

  By this means, fine water negative ions can be stably generated as described above, and the same bathroom space as described above can be created.

In addition , the electrostatic atomizer and the drive control circuit of the electrostatic atomizer are provided as an integrated unit.

  By this means, it can be easily incorporated into the main body and can be easily replaced on the market.

  Further, the electrostatic atomizing device is characterized in that the generator is provided so as to face downward.

  By this means, since the generating part is directed downward, the water molecule can be easily made fine by the overlap of the self-weight of the water molecule and the electrostatic attractive force. For this reason, as described above, fine water negative ions can be stably generated, more fine water negative ions can be supplied in the bathroom, the mold floating in the bathroom is removed, and the bathroom is less prone to mold. A space can be created.

  In addition, the operation is performed in an operation mode for drying the electrostatic atomizer for a predetermined time before the operation of the electrostatic atomizer.

  By this means, the electrostatic atomizer can always be operated from a dry state, so that fine water negative ions can be stably generated.

  Further, the operation is performed in an operation mode in which the amount of air flowing through the bypass circulation air passage provided with the electrostatic atomizer is increased for a certain period of time before the electrostatic atomizer is operated.

  By this means, since the electrostatic atomizer can be operated from the state where dust is not always attached, fine water negative ions can be stably generated.

  In addition, a detection means for detecting fine water negative ions is provided in the vicinity of the outlet, and a control means for controlling the amount of blown air is provided.

  By this means, it is possible to always supply a certain amount of fine water negative ions into the bathroom.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

When a cool breeze is performed, the heat source heater 11 is stopped), and the air is blown out again from the outlet 3 into the bathroom. The wind blown at this time includes those that wrap mold fungi in fine water, and these things quickly adhere to the floor surface, so it is possible to reduce the floating mold fungus is there. 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.

  The mechanism of the electrostatic atomizer 10 will be briefly described. The discharge electrode 12 and the counter electrode 13 are provided. A high voltage is applied between the discharge electrode 12 and the counter electrode 13 to atomize water molecules attached to the discharge electrode 12. , Release fine water negative ions. At this time, water molecules are required for the discharge electrode 12, and a Peltier element 14 is incorporated as means for supplying the water molecules, and the discharge electrode 12 is cooled by the Peltier element 14 by applying a voltage to the Peltier element 14. Then, condensed water is generated at the discharge electrode 12, and the condensed water is atomized. At this time, the heat generated from the Peltier element 14 is dissipated by the radiation fin portion 15.

  At this time, the radiating fin portion 15 of the electrostatic atomizer 10 is provided in the exhaust air passage 7, the radiating fin portion 15 is cooled by the exhaust air, and the generating portion 16 (opposite the discharge electrode 12) of the electrostatic atomizer 10.

(Embodiment 5)
FIG. 8 is a block diagram relating to the fifth embodiment of the present invention.

  Since the discharge electrode 12 faces downward, the water molecules condensed on the discharge electrode 12 are easily transmitted to the tip of the discharge electrode 12, and the attraction force generated by the self-weight of the water molecules and the discharge of the discharge electrode 12 and the counter electrode 13 electrostatically. As a result, water molecules are more easily atomized, and fine water negative ions can be stably supplied into the bathroom. In addition, even if excessive dew condensation water is generated and collected on the discharge electrode 12, the discharge electrode 12 is directed downward, so that it is easily separated from the discharge electrode 12 by the weight of the water molecule itself, Because of the amount of water molecules, stable atomization can be performed continuously.

(Embodiment 6)
FIG. 9 is a flowchart relating to an embodiment of claim 7 of the present invention.

  A command for operating the electrostatic atomizer 10 is transmitted from a main board (not shown) of the main body, receives the signal, and thereafter, an operation mode for drying the electrostatic atomizer 10 for a certain time (as an example) (Dry operation or cool wind operation). After that, if the electrostatic atomizer 10 is stabilized and the atomization phenomenon continues, the drying operation mode is terminated, and the operation of the electrostatic atomizer 10 is continued. If the electrostatic atomizer 10 cannot continue stable operation, the electrostatic atomizer 10 is temporarily stopped and the operation mode for drying the electrostatic atomizer 10 is continued. Again, let us say that the electrostatic atomizer 10 determines whether or not the stable atomization phenomenon continues.

  One determination as to whether the electrostatic atomizer has stabilized is a method of detecting a discharge current and determining whether the discharge current is controlled within a specified value range.

  Here, an example of a time chart will be described. It is assumed that the operation mode for drying the electrostatic atomizer 10 is a 30-minute operation, and thereafter whether the electrostatic atomizer 10 continues a stable atomization phenomenon is 3 If the atomization phenomenon is stabilized, the operation of the electrostatic atomizer 10 is continued. On the contrary, when the atomization phenomenon is not stable, the operation mode for drying the electrostatic atomizer 10 is again operated for 15 minutes, and it is again determined whether the electrostatic atomization apparatus 10 continues the stable atomization phenomenon for 3 minutes. Then, this flow is repeated until it is determined that the electrostatic atomizer 10 is stable.

(Embodiment 7)
FIG. 10 is a flowchart relating to an embodiment of claim 8 of the present invention.

  As described above, the air volume in the operation mode for drying the electrostatic atomizer 10 is increased, the dust adhering to the generator 16 of the electrostatic atomizer 10 is blown off, and the electrostatic atomizer 10 is operated. This is a flow that causes a stable atomization phenomenon to continue.

  At this time, it is assumed that the air volume increase degree is proportional to the operation frequency of the electrostatic atomizer.

  When the frequency of operation of the electrostatic atomizer 10 is high (when it is used about once a month. In other words, when the interval at which the electrostatic atomizer is stopped is relatively short), the increase in air volume is 1. It becomes proportional (up the number of revolutions by 10%), and as the interval of further stopping becomes longer, it will be proportional to the flow that operates at twice the air volume when it has stopped for more than one year.

FIG. 11 is a block diagram showing an embodiment of claim 9 of the present invention.

  When the electrostatic atomizer 10 is in operation, the outlet 3 is provided with detection means 24 for detecting the amount of fine water negative ions, and obtained by the detection means 24 for detecting the amount of fine water negative ions. Comparing the detected value with the amount of fine water negative ions (set value) stored in advance in the microcomputer storage means (not shown), the control means 25 for controlling the blown air volume is provided, and the amount of fine water negative ions is small. In this case, an instruction to increase the rotation speed of the motor that drives the fan 4 is sent from the control means 25 that controls the blown air volume, and as a result, the fine water minus ion quantity (increase the air quantity and store the fine water minus ion quantity ( Set value) so that the same amount of fine water negative ions can be released at all times.

  The bathroom ventilation dryer of the present invention generates a stable amount of fine water negative ions, reduces floating mold, makes it difficult for mold to form, and can create a bathroom space with reduced odor.
