(Embodiment 1)
FIG. 1 is a side configuration diagram showing the bathroom heating / drying machine according to Embodiment 1 of the present invention. In FIG. 1, the main body 1 of the bathroom heating / drying machine according to the present embodiment includes a blower 2 that blows air into the bathroom, a blower air passage 3 through which air blown from the blower 2 circulates, and heats the air. An air heating unit 4 for generating fine water droplets, and a fine water droplet generating air passage 6 through which fine water droplets generated by the fine water droplet generating unit 5 circulate. Furthermore, the ventilation air path 7 which exhausts the air in a bathroom, the blower outlet 9 which blows off air in a bathroom, and the control part 8 which controls the operation | movement of the ventilation part 2, the air heating part 4, and the fine water droplet production | generation part 5 are provided. The controller 8 further includes an operation of generating fine water droplets generated by the fine water droplet generation unit 5 and supplying the water into the bathroom, and an operation of circulating air blowing that circulates air into the bathroom by the blower unit 2. Is alternately repeated a plurality of times.

The blower unit 2 blows air into the bathroom via the blower air passage 3. The fine water droplet generation unit 5 generates fine water droplets that do not feel wet, and supplies the fine water droplets into the bathroom via the fine water droplet generation air passage 6. An open / close bumper 10 is installed in the blower air passage 3, and an open / close bumper 11 is installed in the fine water droplet generation air passage 6. A variable wind direction louver 12 is provided at the air outlet 9 as an air flow control unit. An odor detector 13 for detecting odor components is provided in the ventilator 7.

In the above configuration, when the clothes suspended in the bathroom are deodorized, the open / close bumper 11 is opened, and the fine water droplets generated by the fine water droplet generation unit 5 are supplied to the bathroom through the fine water droplet generation air passage 6. A so-called fine water droplet generation operation is performed. At this time, the variable wind direction louver 12 controls the direction of the wind so that it does not directly hit the clothing, so that the interior of the bathroom is uniformly filled with fine water droplets and becomes hot and humid (for example, 30 ° C. to 40 ° C.).

Next, the open / close bumper 11 is closed, the open / close bumper 10 is opened, and the circulating air blowing operation is performed in which the air blowing unit 2 performs the circulating air blowing. Or the air heating part 4 is used and the heating circulation ventilation which heated the air (for example, 40 to 50 degreeC) is performed. At this time, air is blown in the direction of clothing by the variable wind direction louver 12, and at the same time, ventilation in the bathroom is performed by the ventilation device 7. Since the process of moisture adsorption and evaporation is heavily involved in the deodorization of clothing, it does not supply water droplets or circulate for a long time, but supplies fine water droplets (operation for generating fine water droplets) and circulating airflow. Control is performed to alternately repeat the process of evaporating the adsorbed moisture (circulation air blowing operation).

According to such a configuration, since the interior of the bathroom is uniformly filled with fine water droplets, the fine water droplets can be evenly adsorbed to clothing. At the same time, since the wind controlled by the variable wind direction louver 12 passes through the fibers by the air blowing operation, the moisture adsorbed efficiently is evaporated, and at the same time the odor component is volatilized to deodorize the clothes. Is made. Therefore, deodorization can be performed in a short time, and efficiency with respect to input energy can be improved.

Contrary to the above, when the control of the variable wind direction louver 12 is a control in which air is blown in a direction other than the clothing 14 during the circulation air blowing operation and fine water droplets are supplied in the direction of the clothing 14 during the operation of generating fine water droplets. But the same effect can be obtained.

At this time, during the operation of generating fine water droplets, the fine water droplets can be supplied in the direction of the clothing 14 to fill the vicinity of the clothing 14 with the fine water droplets. Moreover, at the time of the operation | movement of circulation ventilation, it can ventilate in directions other than the clothing 14, and the temperature in a bathroom can be made uniform quickly. Therefore, the adsorption effect of the odor adhering to the garment 14 is enhanced, and the odor can be deodorized in a short time without damaging the garment 14. Therefore, the efficiency can be improved with respect to the input energy.

Moreover, since the odor component deodorized from the clothing and suspended in the bathroom can be removed by the ventilation operation, the odor component can be prevented from reattaching to the clothing.

Further, by controlling the wind direction with the variable wind direction louver 12, it is possible to reduce the deodorization unevenness due to the part of the clothing 14, and to stably obtain the deodorization performance.

In the present embodiment, an odor detector 13 for detecting an odor component, for example, an odor sensor, is provided in the ventilator 7, and the odor component in the air discharged to the outside during the ventilation operation can be detected. Therefore, the time of deodorizing operation and ventilation operation is automatically set according to the odor intensity of the clothing 14. That is, since it can drive | operate by the optimal driving | running time by the odor intensity | strength of the clothing 14, energy can be used efficiently, a deodorizing nonuniformity can be reduced, and the stable deodorizing effect can be acquired. Furthermore, since the odor filled in the bathroom can be sufficiently removed until the odor disappears, it is possible to prevent the odor from leaking outside the bathroom, so that deodorization can be performed without causing discomfort.

In addition, during the operation of generating fine water droplets, it is possible to eliminate the waste of equipment shutdown and eliminate the time lag at the time of operation switching by controlling the circulation ventilation and ventilation operation simultaneously for a certain period of time. Since fresh fine water droplets pass through the clothing, a high deodorizing effect can be obtained and the deodorizing operation time can be shortened. That is, when the circulation air blow operation and the ventilation operation are performed after the operation of generating fine water droplets, the high temperature and humidity state by the operation of generating fine water droplets is reset once, so that the efficiency becomes worse than the simultaneous operation. Therefore, it is impossible to ventilate the odor separated from the clothing in real time and discharge it outside, and the air in the bathroom cannot be kept fresh. However, in the present embodiment, such a problem is eliminated because deodorization can be performed while always maintaining a high temperature and high humidity state by the operation of generating fine water droplets.

(Embodiment 2)
FIG. 2 is a side configuration diagram showing a bathroom heating / drying machine according to Embodiment 2 of the present invention. In FIG. 2, the bathroom heater / dryer according to the present embodiment has the fine air that has passed through the air flow path 3 and the fine water droplet generation air path 6 in front of the air flow path 3 and the fine water drop generation air path 5. A converging air passage 19 through which a water droplet flows is provided, and a switching damper 15 for switching the air passage is provided at a connection portion between the air blowing passage 3 and the fine water droplet generating air passage 6 and the confluence air passage 19. The switching damper 15 is provided with the functions of the open / close bumper 10 and the open / close bumper 11 in the first embodiment.

Even with such a configuration, the same effect as in the first embodiment can be obtained. Furthermore, according to the present embodiment, space saving and cost reduction can be realized.

(Embodiment 3)
FIG. 3 is a side configuration diagram showing a bathroom heater / dryer according to Embodiment 3 of the present invention. In FIG. 3, the difference from

Embodiments

1 and 2 is that a fine water droplet generation unit 5 is provided in the blowing air passage 3, and the blowing air passage 3 and the fine water droplet generation air passage 6 are shared as the same air passage. In addition, a clothing detection unit (object detection unit) 18 for detecting the clothing 14 is provided.

In the above configuration, when the air blowing is performed toward the clothing 14 when the circulation air blowing operation is performed after supplying the fine water droplets, the temperature is lower than the surroundings when the moisture absorbed by the clothing 14 evaporates. Therefore, the position of the garment 14 can be grasped by using the clothing detection unit 18, for example, an infrared temperature sensor such as a thermosensor. The airflow can be automatically controlled according to the result. Therefore, since the control can always be performed with the same operation regardless of the position of the garment 14, the effect of deodorization can be stably obtained, and the efficiency with respect to the input energy can be improved.

In addition, since the blower air passage 3 and the fine water droplet generating air passage 6 are the same air passage, the bathroom heating / drying machine can be reduced in size, and the cost can be reduced and the workability can be improved.

(Embodiment 4)
FIG. 4 is a perspective view showing a variable wind direction louver of a bathroom heating / drying machine according to Embodiment 4 of the present invention. In FIG. 4, the difference from Embodiments 1 to 3 is that a variable wind direction louver 12 is provided with a plurality of wind direction louver outlets 16, and a wind direction damper 17 is provided in each of the wind direction louver outlets 16.

With the above configuration, since the airflow can be controlled by the position and amount of the clothing 14, it is possible to operate with the minimum necessary airflow and operation time. Therefore, the efficiency with respect to the input energy can be improved without damaging the clothes with high-temperature steam.

(Embodiment 5)
FIG. 5: is a block diagram which shows the blower outlet for wind direction louvers of the bathroom heating dryer of Embodiment 5 of this invention. FIG. 6 is a perspective view showing an air outlet louver outlet of the bathroom heater / dryer. 5 and 6, the difference from Embodiments 1 to 4 is that each of the plurality of wind direction louver outlets 16 is independently operated.

With the above-described configuration, it is possible to control air blowing in multiple directions at the same time, and at the same time, air can be sent in a wider range. Therefore, the deodorization efficiency is improved, and the efficiency with respect to the input energy can be improved without damaging the clothes with high-temperature steam.
(Example)
EXAMPLES Hereinafter, although an Example demonstrates this invention in detail, this invention is limited to the following description and is not interpreted at all.

The deodorization effect test of the odor adhered to the cloth was performed by sensory evaluation based on the odor intensity. First, a cloth (suit fabric, wool 100%) was cut into a length of 10 cm and a width of 5 cm to obtain a test piece. This was suspended in a 50 L acrylic box, one cigarette was burned inside, and it was allowed to stand still for 1 hour in a sealed state to attach a cigarette odor to the test piece.

The test piece with odor attached was placed in the bathroom. The bathroom was 1 tsubo (width 1.6 m × depth 1.6 m × height 2.2 m), and was carried out in a unit bath in which the bathroom heating dryer of the present invention was installed on the ceiling. In addition, in order to compare the effect by the difference in a wind direction, the test piece was fixed to the blower outlet of the bathroom heating dryer and the bathroom corner among bathrooms. The test piece was fixed on a clothes hanger with a clip and hung on a drying basket. Dried persimmons were fixed at a position 20 cm high from the ceiling. After fixing, the bathroom door was closed and the bathroom heating dryer was operated to deodorize. First of all, after performing the water droplet spraying operation for 10 minutes with the wind direction not directly hitting the test piece being carried out, the heating direction is continuously swirled for 10 minutes so that the wind direction is swung directly on the test piece. I went. In addition, ventilation operation with a ventilation device was carried out through deodorization operation.

After the deodorizing operation, the test piece was taken out of the bathroom and sealed in an odorless bag. The test pieces after deodorization were subjected to sensory evaluation with a 6-step odor intensity in a separate room whose room temperature was adjusted to about 25 ° C., and the odor intensity was determined. These results are shown in Table 1.

(Comparative example)
The test piece to which the odor was attached as in Example 1 was replaced in the bathroom and left in the separate room with the room temperature adjusted for the same time to obtain a sample for evaluation by natural decay of the odor. The results are shown in Table 1.

As shown in Table 1, the comparative example had an attenuation of about 0.5 with respect to the initial value, but in the example, both the outlet and the corner showed attenuation of two ranks or more from the initial value. The deodorizing effect was obtained even in the corner far from the blowout port as with the test piece near the blowout port. By directing the spray direction of fine water droplets in a direction other than clothing, the deodorizing effect can be obtained not only in clothing near the air outlet but also in clothing placed in the corner of the bathroom, as in the vicinity of the air outlet. confirmed.

As described above, the present invention generates a blower that blows air into the bathroom, a blower air passage through which air blown from the blower circulates, an air heating unit that heats air, and fine water droplets. And a fine water droplet generation air passage through which fine water droplets generated by the fine water droplet generation unit circulate. Furthermore, a ventilation air passage that exhausts the air in the bathroom, a blowout port that blows out air into the bathroom, and a control unit that controls operations of the air blowing unit, the air heating unit, and the fine water droplet generation unit are provided. Further, the control unit alternately performs a plurality of operations for generating fine water droplets generated by the fine water droplet generating unit and supplying the water into the bathroom, and a circulation air blowing operation for circulating air into the bathroom by the air blowing unit. It has a configuration that is repeated once.

With such a configuration, fine water droplets adsorbing the odor adhering to the object can be efficiently removed, so that the object can be deodorized in a short time without damaging the object with high-temperature steam. Therefore, the heating dryer which can raise efficiency with respect to input energy can be provided.

Further, according to the present invention, the control unit blows air in the direction of the object to be dried during the operation of circulating air blowing, and the fine water droplets in a direction different from the object during the operation of generating fine water droplets. It has a configuration to supply.

With such a configuration, the air is blown in the direction of the object during the operation of circulating air blowing, and the fine water droplets are supplied in the direction other than the object during the operation of generating fine water droplets. By supplying fine water droplets, the room can be uniformly filled with fine water droplets, and during the operation of circulating air blowing, the air can be blown in the direction of the object and passed through the fibers of the clothing. Therefore, since the fine water droplets adsorbing the odor adhering to the object can be efficiently removed, the object can be deodorized in a short time without damaging the object with high-temperature steam. Therefore, the efficiency can be improved with respect to the input energy.

Make the temperature uniform quickly. Therefore, when the amount of the object is small, fine water droplets can be efficiently supplied to the object, so that the adsorption effect of the odor adhering to the object is enhanced, the object is not damaged, and the input energy is small. Can be deodorized in a short time. Therefore, the efficiency can be improved with respect to the input energy.

Further, the present invention has a configuration in which an open / close damper is provided in each of the blower air passage and the fine water droplet generating air passage.

With such a configuration, the open / close dampers in the blower air passage and the fine water droplet generating air passage can be opened and closed as necessary. That is, since the operation of generating fine water droplets and the operation of circulating air can be finely controlled, the efficiency with respect to the input energy can be improved without damaging the clothes with high-temperature steam.

Further, the present invention provides a converging air passage that circulates the air that has flowed through the air flow path and the fine water droplets that have flowed through the fine water drop generation air path at the tip of the air flow path and the fine water drop generation air path. A switching damper for switching the air passage is provided at the connection portion between the air passage and the fine water droplet generation air passage and the confluence air passage.

With such a configuration, it is possible to unify the air path of the blowout and to switch between the generation of fine water droplets and the circulation airflow with a damper. That is, by reducing the number of dampers, it is possible to save space and reduce costs by the amount of the reduced damper. At the same time, the efficiency with respect to the input energy can be improved without damaging the clothes with high-temperature steam.

Further, the present invention has a configuration in which a fine water droplet generation unit is provided in the air blowing path, and the air blowing path and the fine water droplet generation air path are shared.

Therefore, cost reduction and workability can be improved by downsizing.

Moreover, this invention has the structure which provided the airflow control part in the blower outlet. With such a configuration, it is possible to determine the direction in which the air current is blown and to concentrate the air current in the vicinity of the object. Therefore, the deodorizing performance can be stably obtained, and the efficiency with respect to the input energy can be improved without damaging the clothes with high-temperature steam.

Also, the present invention has a configuration in which the airflow control unit is a variable wind direction louver that changes the direction of the airflow. With this configuration, the entire object can be operated so as to be exposed to the airflow. Therefore, the deodorizing unevenness by the site | part of a target object can be reduced, and deodorizing performance can be obtained stably. Therefore, the efficiency with respect to the input energy can be improved without damaging the object with high-temperature steam.

Further, according to the present invention, the variable wind direction louver has a configuration including a plurality of variable wind direction louver outlets and variable wind direction dampers provided at each of the variable wind direction louver outlets.

With this configuration, the amount of airflow can be adjusted according to the position and amount of the object. Therefore, it can be operated with the minimum necessary air volume and operation time, and the efficiency with respect to the input energy can be improved without damaging the clothes with high-temperature steam. Moreover, this invention has the structure which operated each of the said several blower outlet for variable wind directions independently.

This configuration has the effect of blowing air in multiple directions at the same time. That is, since the air can be blown in a wider range at the same time, the deodorization efficiency is improved. Therefore, the efficiency with respect to the input energy can be increased without damaging the clothes with high-temperature steam.

Further, the present invention has a configuration in which an object detection unit that detects an object is further provided. With this configuration, the airflow can be automatically controlled according to the position of the object. That is, by detecting an object, the same operation can always be controlled regardless of the position of the object, and the efficiency with respect to input energy can be improved without damaging clothes with high-temperature steam.

Further, the present invention has a configuration in which an odor detection unit for detecting an odor component is provided in the ventilation air passage. With this configuration, the time for the deodorizing operation and the ventilation operation can be automatically set according to the odor intensity of the object. That is, since it can drive | operate by the optimal driving | running time with the odor intensity | strength of a target object, energy can be used efficiently, a deodorizing nonuniformity can be reduced, and the stable deodorizing effect can be acquired. In addition, since the odor filled in the bathroom can be sufficiently removed, the odor is prevented from leaking outside the bathroom, and uncomfortable feeling is not given. Therefore, the efficiency with respect to the input energy can be increased without damaging the clothes with high-temperature steam.

Further, the present invention has a configuration in which during the operation of generating fine water droplets, the operation of circulating air and the ventilation operation of exhausting the air in the bathroom are performed simultaneously for at least a predetermined time. With such a configuration, it is possible to eliminate the waste of the operation stop of the device and to eliminate the time lag at the time of operation switching. Accordingly, since fresh fine water droplets always pass through the clothing, a high deodorizing effect can be obtained and the deodorizing operation time can be shortened. Therefore, the efficiency with respect to the input energy can be improved without damaging the clothes with high-temperature steam.
