  In the mist generation drying circulation box 3, there is mist generation means 9 for misting hot water supplied from the hot water heater 7 through the hot water supply pipe 8. The mist sauna mists hot water from the mist generating means 9 and removes water droplets with the eleminator 10 and then sprayed into the bathroom. The particle size of the mist generated by this has a particle size of about 0.1 μm to 10 μm. The water droplets removed by the eleminator 10 are collected by the drain 11 and drained. Moreover, the heat exchanger 12 which is the air heating means which heats the air in a bathroom, and the air blower 13 are provided as a circulating air blowing means for circulating air in the bathroom. The temperature detection means 14 for detecting the temperature in the bathroom and the humidity detection means 15 for detecting the humidity in the bathroom are provided in the mist generation drying circulation box 3.

  The bathroom ambient air temperature detecting means 16 is provided outside the bathroom inner wall and the heat insulating material, but if facing the bathroom inner wall and the heat insulating material, either the ventilation box 2 or the mist generation drying circulation box 3 is provided. It is preferable to provide it. In this case, the air in the attic is measured as the ambient air temperature in the bathroom. On the other hand, it can be extended by wiring to the side of the bathroom surrounding the lower side or floor.

  The operation control instruction circuit 4 controls the operation method of the bathroom heater / dryer 1 such as switching, adjustment and setting of variables of various operation modes, such as mist spray operation, heating operation, circulating air operation, drying operation, and ventilation operation. is there. Here, the mist spraying operation is an operation of spraying hot water supplied from the hot water heater 7 through the hot water supply pipe 8 into the bathroom by the blower 13 which is a circulating air blower, by mist generation means 9. The drying operation is an operation in which the exhaust fan 5 is operated and the air in the bathroom is exhausted outside the bathroom from the opened exhaust damper 6, or the air is heated by the heat exchanger 12 while the air in the bathroom is exhausted outside the bathroom. It refers to a heating and circulating air blowing operation in which the air thus circulated into the bathroom by a circulating air blowing means. The heating operation is an operation method for circulating and blowing the heated air that has passed through the heat exchanger 12 that is an air heating means into the bathroom by the blower 13 that is a circulating air blowing means, and raising the temperature in the bathroom. At this time, unlike the drying operation, since the exhaust fan 5 and the exhaust damper 6 in the ventilation box 2 are not used, the warmed air is not released outside the bathroom, and the temperature inside the bathroom can be increased efficiently. . The temperature of the blown air in the heating operation is adjusted to be between 40 ° C. and 60 ° C. by the heating temperature control means. The heating temperature control means is configured by means for adjusting the temperature of hot water supplied to the heat exchanger 12, a hot water amount adjusting valve 17 to be supplied, and means for detecting the blown air temperature, and the blown air temperature is within a set range. Operation control is performed so as to enter.

  The operation control instruction circuit 4 includes an air blower 13, an exhaust fan 5, an exhaust damper 6, an electromagnetic valve such as a hot water adjustment valve 17 provided in the hot water supply pipe 8, an airflow control means 18 for controlling the airflow direction of the airflow, and temperature detection. It is connected to the means 14, the humidity detecting means 15, the bathroom ambient air temperature detecting means 16 and the like by wiring. In addition, a remote controller (remote controller) 19 in the bathroom and a dressing room remote controller 20 are provided as operation means, and the user can select and execute the operation method, operation temperature, operation time, and the like by button operation. As the temperature detecting means 14 in the bathroom and the air temperature detecting means 16 in the bathroom, there is a sensor for measuring the surface temperature by infrared rays or the like. However, when the water droplet adheres, the surface temperature may not be measured. A thermocouple sensor which is difficult to adhere and is water resistant is preferable. It is also effective to give the surface a water repellent or hydrophobic treatment. The temperature detector 14 in the bathroom detects the temperature in the bathroom, and is preferably capable of detecting, for example, a temperature range of 5 ° C. or more and 60 ° C. or less which can actually occur in the bathroom.

  The temperature detection means 14 in the bathroom is preferably provided inside the mist generation drying circulation box 3 of the bathroom heating dryer 1 as shown in FIG. 1, but is not limited to this as long as it is in the bathroom. However, when installing in a bathroom where water droplets adhere, it is necessary to select a means that does not hinder detection due to water droplets adhering. Also, when the temperature detecting means 14 in the bathroom detects a temperature in the bathroom of 50 ° C. or higher, in order to minimize the adverse effects on the bathroom members, the bathroom TV and the radio, the mist spraying operation or It is preferable to incorporate an operation control method in which the drying operation is stopped into the operation control instruction circuit 4.

  As the humidity detection means 15 in the bathroom, there is a sensor made of lithium chloride, ceramic, or the like, but it may be combined with water droplets adhering to the surface and humidity measurement may not be possible. By using a humidity sensor that uses a polymer film as the material, it is possible to minimize humidity measurement obstruction due to the adhesion of water droplets. Further, the humidity detection means 15 in the bathroom only needs to detect the humidity in the bathroom. For example, the humidity detection range is preferably 40% to 100%.

  The humidity detecting means 15 in the bathroom is preferably provided inside the bathroom heater / dryer 1 as shown in FIG. 1, but is not limited to this as long as it is in the bathroom. However, when it is provided at a site where water droplets adhere in the bathroom, it is necessary to select a means that does not hinder detection due to the adhesion of water droplets.

  The drying operation control means for drying the wall surface in the bathroom is programmed to select an operation method according to the temperature and humidity measured by the temperature detection means 14, the humidity detection means 15, and the bathroom ambient temperature detection means 16. deep. Immediately after bathing or sauna bathing, the bathroom is filled with high-humidity air, and when drying operation is performed by heating and circulation blowing operation in that state, the energy of heating and blowing is absorbed by the high-humidity air, It is difficult to reach the wall surface, and much energy is required to dry the wall surface. On the other hand, when the ventilation operation is performed, the air and the wall surface in the bathroom are gradually cooled to increase the dew condensation, thereby increasing the time until the interior of the bathroom is dried. Therefore, when the ventilation starts for a short time, the high humidity air is decreased, and the temperature starts to decrease, the heating circulation ventilation operation or the circulation ventilation operation is started, and the air in the bathroom is stirred and moved to the vicinity of the wall surface. By providing the airflow, the drying operation can be performed efficiently so as not to increase the condensation.

  The heating and circulation fan operation and the start timing of the circulation fan operation are obtained by determining the dew point of the wall surface based on the air condition in the bathroom by the temperature detection means 14 and the humidity detection means 15 and the wall surface temperature determined from the bathroom ambient temperature detection means 16. After the ventilation operation starts, it is judged by the preliminary ventilation judgment means whether the temperature and humidity at which dew condensation increases under the air condition in the bathroom, and when the dew point is reached, the start of the heating circulation ventilation operation or the circulation ventilation operation is immediately judged. . The time until the wall surface reaches the dew point with the air in the bathroom reaches within 30 minutes after the start of ventilation operation, and the temperature and humidity are detected at a short interval of about 10 seconds to 1 minute. There is a need to do.

  When the circulating air blowing operation is performed, since the interior of the bathroom is not heated, water droplets on the wall surface are evaporated by the air current, and the relative humidity in the bathroom is greatly increased. The circulating air blowing operation is effective for drying the wall surface when the temperature of the wall surface in the bathroom is higher than the air temperature around the bathroom and heat is released. On the other hand, after the wall surface temperature becomes equal to the air temperature around the bathroom, it is often not possible to obtain a great effect for shortening the drying time compared to the ventilation operation alone. Therefore, when the temperature of the agitated air in the bathroom detected by the temperature detection means 14 and the temperature of the bathroom surroundings by the bathroom ambient temperature detection means 16 become equal, the circulating air blowing operation is terminated, and the ventilation operation is performed thereafter. It is most effective for the energy used to dry the inside.

  On the other hand, when performing the heating circulation ventilation operation, the water droplets adhering to the wall surface are easily evaporated by blowing heated air. Moreover, since the temperature of the wall surface rises due to the heat generated by the heated air, the vapor pressure of the water droplets increases and further drying is promoted. At this time, water drops evaporate in the bathroom, but the humidity in the bathroom decreases. This indicates that the input heat amount is larger than the drying rate of moisture in the bathroom, and the bathroom is in a state of being easily dried, and the bathroom can be dried in a short time. Therefore, it is judged from the humidity value in the bathroom that the air in the bathroom is easy to dry when it becomes 40% or less. I do. However, since the heat circulation air blowing operation uses a large amount of energy, it is a realistic time to use it on a daily basis rather than operating for a long time, rather than operating for a long time. In addition, by controlling the amount to 40% or less, it is effective in preventing the growth of mold in the bathroom because the combined water attached to the mold mycelium is removed and the mycelium is dried to suppress the growth.

  After stopping the heating / circulation fan operation or the circulation fan operation, the ventilation operation is continued.At this time, the humidity in the bathroom also decreases as the amount of water drops on the wall surface decreases, and the drying in the bathroom is reduced. When finished, the humidity stabilizes. When this decrease in humidity stops, it can be determined that the drying of the bathroom has been completed. However, considering the variation of the humidity sensor as the humidity detection means 15, the ventilation operation is continued for another hour, and the increase in humidity is 10%. If the percentage does not increase as a guide, it is assumed that the inside of the bathroom has been completely dried, and the inside of the bathroom can be surely dried by determining whether the quick drying mode has ended.

  The determination of whether to perform such a heating circulation ventilation operation or a circulation ventilation operation is performed by the season determination means. The season determination unit is programmed to select an operation method according to the temperature and humidity measured by the temperature detection unit 14 and the humidity detection unit 15. For example, in seasons where mold contamination is likely to progress, such as in the summer and rainy seasons, if the outside air continues to be at a temperature of 20 ° C or higher and humidity of 60% or higher, the circulating air Even if it is operated or ventilated, it is difficult to dry the wall surface, and the state where mold tends to propagate continues, and there is a risk that mold contamination will progress. For this reason, in the case of such temperature and humidity, it is preferable to select and use a heating and circulating air blowing operation that can be dried in a short time to reduce the humidity.

  On the other hand, in the season when mold is difficult to propagate, for example, in the outside air from the middle to winter, the temperature and humidity are low (less than 20 ° C., less than 60%), and the mold growth is small because it is not suitable for mold propagation. In such a season, the circulation air blowing operation is selected and used. Even without performing the heating circulation ventilation operation, it becomes possible to sufficiently suppress the drying of the wall surface and the growth of mold by lowering the temperature and humidity in the bathroom by ventilation and circulation ventilation. By performing such control, the energy required for heating can be reduced, and energy-saving drying operation control means can be obtained.

  As the temperature and humidity used for the determination by the season determination means, the temperature and humidity at the time when the lowest temperature measured within one month is measured from 24 hours is adopted. When determining the season, if the temperature is set to the highest temperature, the temperature in the bathing or sauna bath may be adopted, and the control for eliminating this becomes complicated. Therefore, if the minimum temperature is used, such a necessity is not necessary, and the season can be determined with high accuracy. At this time, although fluctuations for one day may be observed, it becomes possible to make more stable determination by using a value measured in a range where the season does not change for several days to one month.

  Such a bathroom drying operation control means is provided with a button activation means outside the bathroom, on the remote control of the dressing room, etc. as a quick drying mode, and is automatically controlled.

  The mold determining means programs a mold index value data table indicating a mold breeding level determined in advance from the temperature, humidity, and measurement time interval on the microcomputer in the operation control instruction circuit 4, and determines the mold index from the measured temperature and humidity. The value is determined to determine the mold reproduction level. In the dry state without bathing or sauna bathing, the wall surface condition can be determined from the measured temperature and humidity, but water drops adhere to the wall surface during the bathing period until the quick drying mode is terminated. In particular, during the execution of the quick drying mode, even if the humidity of the air is reduced by the heating circulation air blowing operation or the circulation air blowing operation, water drops still adhere to the wall surface and dissociation from the reality is observed. Therefore, during the period of this rapid drying mode, it is possible to make the wall surface thrive by determining that the humidity is 90% to less than 100% until it is automatically terminated due to a change in humidity, thereby preventing underestimation of the mold reproduction level. be able to.

  In order to display the determination result of the mold breeding level by the mold determining means, the display means 21 is provided on a remote control such as a dressing room outside the bathroom. The display means is a light emitting diode display or a liquid crystal panel display. The display means 21 is preferably provided in the dressing room remote controller 20, but is not limited thereto. When the mold propagation level is equal to or higher than a preset threshold value, the user can know that mold contamination has progressed by changing the color of the light emission display of the display means from green to yellow or red.

  In this way, by efficiently drying the wall surface and determining the mold propagation level, the mold grows by recognizing the presence of mold before the mold grows in the bathroom and the contamination progresses. Become a bathroom heating dryer that can maintain the bathroom continuously.

(Embodiment 2) Fungal growth suppression effect A growth suppression test by wet heat was performed using Cladosporium cladosporioides (NBRC6348, hereinafter referred to as Cladosporium), which is the most well-known fungus that propagates in the bathroom. The method is described below.

  Cladosporium colonies that were slanted in a test tube with PDA medium were pipetted with 1 mL of sterile water to collect spores. To a 50 mL centrifuge tube, 1 mL of a spore recovery solution and 24 mL of sterilized water were added, and shaken for 10 minutes at room temperature and 200 rpm to obtain a test solution. 1 mL of the test solution was placed in a 1.5 mL microtube, subjected to heat shock using a block heater, and then applied onto a PDA medium in a petri dish and cultured at 25 ° C. for 4 days. Thereafter, the number of colonies was visually counted to calculate the number of viable bacteria. The survival rate was calculated by dividing the number of viable bacteria after the moist heat action by the number of viable bacteria before the moist heat action.

  As shown in FIG. 2, even when wet heat was applied at 25 ° C. or 35 ° C. for 2 hours, the survival rate of cladosporium was almost 100%, and it was not possible to suppress the growth of cladosporium. However, it was possible to suppress about 80% in 1 hour with wet heat at 40 ° C. and to suppress about 90% in 2 hours. In addition, at 45 ° C. wet heat, it could be almost completely annihilated by exposure for 0.5 hours.

  In this way, Cladosporium can be killed by applying moist heat of 40 ° C. or higher for 1 hour or more under water immersion conditions, and when the wall surface is wet with water droplets or condensation in the bathroom, It shows that it is possible to suppress without increasing the temperature by increasing the temperature.

  Similarly, a growth suppression test using moist air was performed using Cladosporium. The method is described below.

  Spores were recovered by pipetting colonies cultured in a test tube with PDA medium in 1 mL of sterile water. To a 50 mL centrifuge tube, 1 mL of spore recovery solution and 24 mL of sterilized water were added, and shaken at room temperature and 200 rpm for 10 minutes to obtain a test solution. Put 0.1 mL of the test solution into a 25 mL centrifuge tube, let it completely air dry over about 2 hours, put it in a constant temperature and humidity chamber set at 25, 35, 40 or 45 ° C. and 99% in advance, Temperature and humidity shocks were applied to the dried spores. Thereafter, 5 mL of sterilized water was added to the centrifuge tube and vortexed to disperse the dried spores in sterilized water. The spore was applied onto a PDA medium in a petri dish and cultured at 25 ° C. for 4 days. Then, the number of colonies was counted visually to calculate the number of viable bacteria. The survival rate was calculated by dividing the number of surviving spores after the temperature and humidity shock by the number of surviving spores before the temperature and humidity shock.

  As shown in FIG. 3, Cladosporium could be almost completely annihilated by exposure to humid air at 40 ° C. and 99% for 1 hour.

  Here, as shown in FIG. 4, even in an experiment using Aureobasidium pullans NBRC6353, it was almost completely annihilated by exposure to humid air under conditions of 40 ° C. and 99% for 1 hour. Mold was able to be almost completely killed by exposing it to 40 ° C. and 99% conditions for 1 hour after completely draining moisture. This indicates that mold floating in the air in the bathroom can be suppressed.

(Embodiment 3) Mold determination method Table 1 is a list showing the index value of the mold breeding level used in the mold determination means of the mold determination method of the present invention.

  In the mold determination method, the mold propagation level in the measurement atmosphere is determined by comparing the temperature and humidity (relative humidity) of the measurement atmosphere with a preset index value of the mold reproduction level. The mold breeding level is a value indicating the level of mold growth. If the mold breeding level is small, the mold does not grow so much, and if the mold breeding level is large, the mold grows greatly, Indicates that mold contamination is in progress. The index values shown in the table are a list of mold index values in the time constant τ1, and values are determined for each temperature and humidity. The index value is a value set based on the appearance such as colony size and color density, the amount of bacterial cell components such as the amount of nucleic acid and the amount of protein, etc., and is set in advance based on experimental results and the like. Suppose that the size of the appearance that is judged to be mold stain and the threshold value for the color density are set, and the mold contamination occurs when the threshold value is exceeded. For example, if the size is 2 mm or more, it can be recognized as mold, and if it is 5 mm or more, the level becomes uncomfortable, but the threshold is 2 mm that can be determined as mold. The time constant indicates the measurement time interval in this case.

  When the mold determination method is performed on a program, the calculation process related to the mold breeding level can be omitted by using the time constant. In the conventional method, a mold index value consisting of the mold hyphal elongation rate is determined for each temperature and humidity, and the temperature and humidity changes during the continuous measurement are immediately converted to the mold reproduction level. This is a method of multiplying the values from the time when the mold breeding level has continued and integrating them to obtain the mold breeding level for the total period. Since multiple calculation processes are performed simultaneously, a calculation device including a CPU is required. It is difficult to incorporate it directly into equipment such as a heating dryer. When using the time constant method, it can be implemented by selecting and reading out the mold index value stored in the storage device such as the memory on the microcomputer from the conditions of the time constant, temperature, and humidity. It can also be installed in equipment such as dryers. If the time constant is used, the measurement time interval is limited, but the change in temperature and humidity and the change in mold reproduction level are gradual, and the influence on the measurement accuracy is small. In an environment where a rapid temperature change is not seen, such as a living environment, the time constant should be about 1 to 24 hours, preferably 1 to 6 hours. By setting every 24 hours, the standby power of the measuring device can be reduced, and the measurement work can be omitted.

  The mold index values can be integrated to obtain a total period value. Mold growth speed varies depending on the environment of temperature and humidity, but the mold color remains unless it is decolorized with bleach, etc., so the long-term mold growth level is the temperature and humidity during that period. It can be expressed as the result of summing up the mold propagation levels in response to changes. Therefore, even when the temperature and humidity in the bathroom change, it is possible to know the timing at which mold grows, and it is possible to prevent mold growth by taking measures against mold.

  The mold propagation level varies depending on the type of mold, the hydrophilicity of the surface of the attached object, the surface shape, the presence of nutrients, etc., and therefore it is necessary to set the conditions strictly and obtain the index value. The place contaminated by mold growth is in a state where mold tends to acquire moisture for germination and growth. When judging the state of contamination due to mold growth, it is desirable to conduct a reproduction test under such suitable conditions and set an index value, especially those with a highly hydrophilic surface to be used as the carrier to be attached It is necessary to do.

  As the hydrophilic carrier to which the mold is attached, a substrate such as cellulose, silica gel, or glass fiber can be used. The main mold stains are dark colors such as black, and in order to easily recognize these, it is preferable that they are light colors such as colorless and white. Further, for the purpose of observation, a flat plate, preferably a thin film of 1 mm or less is used. For example, a filter paper can be used for cellulose, and a silica gel plate for thin phase chromatography can be used for silica gel. These need to be dry at first, but there is an operation to equilibrate at a certain temperature and humidity before inoculating the mold so that the mold does not die at low humidity.

  The mold to be used for the test is preferably a cladsporium clamsporioids (NBRC6348, hereafter referred to as cladosporium) or aureobasidium (Aureobasidium puluans NBRC6353), which is a low temperature medium temperature, It is important to widely use molds that grow at various temperatures and humidity such as sexuality, high temperature, or dryness.

  Before inoculating mold, the carrier is impregnated with a nutrient source according to the assumed environment. For example, assuming a bathroom, soap residue, scales, and sebum are considered as nutrient sources for mold. Therefore, as a nutrient source, instead of triglyceride, which is a sebum component, triolein, trilinolein, or olive oil is diluted with a solvent such as n-hexane and impregnated so as to be 0.1 to 1 ml per 10 cm 2. Let It is important that nutrient sources are thoroughly investigated in advance and evaluated using appropriate amounts.

  Mold spores are inoculated on the surface of a carrier impregnated with a nutrient source. A spore solution is prepared so as to have a constant concentration so that a constant amount can be easily inoculated. Mold is pre-cultured in advance on a medium such as potato dextrose agar medium (hereinafter referred to as PDA medium) at 25 ° C. to 30 ° C. for 3 to 7 days to sufficiently form spores. Spores are collected from the surface of the grown mold with a platinum loop, dispersed with a dilute surfactant such as n-octylsulfosuccinic acid, and then diluted with distilled water or washed to prepare a spore solution. A small amount of the prepared spore solution is dropped on a slide glass or a hemocytometer, and the number of spores is counted by observing with a microscope.

  The prepared spore solution is dropped onto the surface of the carrier impregnated with the nutrient source. The area to be dropped varies depending on the evaluation method, but when a mold growth area is used as an evaluation index, inoculation is performed using a thin tube such as a glass capillary so that the area is as small as 1 mm or less. The number of spores to be inoculated is about 10 to the 5th power.

  The mold-inoculated carrier is immediately sealed in a chamber having a controlled temperature and humidity environment and cultured. After culturing for a certain period, it is taken out from the chamber, observed with a microscope or visually, and the colony size and color intensity are measured and digitized using the color as a guide. Alternatively, when the bacterial cell component is used as an indicator, an extract reagent such as an enzyme or a solvent is reacted with the carrier to extract the fungal cell component and measure the component. For nucleic acids, for example, by reacting a crude extract with a mixed solution of phenol and chloroform, separating the nucleic acid, purifying with ethanol, etc., and then determining the concentration from the absorbance, the mold index value that correlates with the amount of bacterial cells is obtained. Can be sought. If the result is one day later, it is repeated in 24 hours to obtain the size per hour. This value is used as a mold index value.

  Table 1 is a numerical value based on the mold size and used as an index value for the time constant τ1. The temperature is 25.1 ° C. or higher and 30.0 ° C. or lower, and the humidity is 90% or higher and 99%. In the following cases, a value of 280 is selected and added to the accumulated value so far. When the threshold value is 800, the cumulative value becomes 840 when the temperature and humidity period lasts three times τ1, and therefore, a lighting display indicating mold contamination is performed by the display means after the third measurement. Moreover, it is possible to qualitatively compare the ease of propagation of mold in the space from the mold index value. Comparing the tendency of mold growth in the 85% space at 28 ° C and the 85% space at 18 ° C based on the mold index value, the mold index value is 90 in the 85% space at 28 ° C, 18 ° C The 85% space has a mold index value of 18. It can be seen that 85% at 28 ° C. tends to grow mold five times.

  By the above method, the mold index value can be obtained for each temperature, humidity, and holding time, and the mold index value can be selected from the measured temperature and humidity to determine mold contamination.

  By drying the interior of the bathroom in a short period of time after taking a bath or after taking a sauna, the growth of mold in the bathroom can be suppressed, and the interior of the bathroom can be kept clean.
