JP 2007-195896 A

  As mentioned above, when it is set as the structure which heats the inside of a washing tub with a heater and accelerates | stimulates decomposition | disassembly of ozone, it is easy to consume comparatively big electric power. In addition, such a configuration is difficult to apply when an object such as deodorant is vulnerable to heat.

  Therefore, the inventors of the present application have considered a method for promoting the decomposition of ozone under other conditions instead of heating. As a result, after the supply of ozone is stopped, the ozone is decomposed by humidifying the inside of the washing tub. I found that it was promoted.

  The present invention has been made on the basis of such new knowledge that the decomposition of ozone is promoted by increasing the humidity, and is a case where the object to be treated is weak against heat while suppressing power consumption. However, an object of the present invention is to provide an ozone treatment apparatus that can shorten the time from when the supply of ozone is stopped until the object to be treated can be taken out.

  An ozone treatment apparatus according to a main aspect of the present invention includes a housing unit that accommodates an object to be processed and is held in a substantially sealed state by closing a door, and an ozone generator that generates ozone to be supplied to the housing unit. , A mist generating unit for generating mist for humidifying the storage unit, an ozone generation step for supplying ozone to the storage unit, and ozone decomposition for decomposing ozone remaining in the storage unit following the ozone generation step And a control unit that executes the process. Here, the control unit operates the mist generation unit in the ozone decomposition step after operating the ozone generation unit in the ozone generation step.

  According to said structure, mist is supplied in a storage chamber in an ozonolysis process, and a storage chamber is humidified. Thereby, since decomposition | disassembly of the ozone which remains in a storage chamber is accelerated | stimulated, time from when supply of ozone is stopped until extraction of a process target object is attained can be shortened. In addition, since the power consumption required for humidification by an ultrasonic humidifier or the like can be made smaller than the power consumption required for heating by the heater, decomposition of residual ozone can be promoted while suppressing power consumption. Further, even when the object to be treated is weak against heat, it is possible to promote the decomposition of residual ozone.

  The ozone treatment apparatus according to the present aspect is provided with a wind generating unit that generates wind in the housing unit and the housing unit, and is capable of discharging mist to the outside by a flow of wind generated in the housing unit. And a hole. In this case, the control unit operates the wind generation unit after stopping the mist generation unit in the ozone decomposition step.

  According to said structure, the user can take out a process target object from a storage part in the state which the humidity in a storage part fell by discharging | emitting mist outside. Therefore, it is possible to prevent the user from feeling uncomfortable by putting his / her hand in the housing portion with high humidity.

  In the ozone treatment apparatus according to this aspect, the storage unit includes an outer tub and a drum that is arranged in the outer tub and is rotatable about a horizontal axis or an inclined axis that is inclined with respect to the horizontal direction. Can be done.

  When it is set as such a structure, the said control part may be set as the structure which rotates the said drum, when the said accommodating part is humidified by the mist from the said mist generating part.

  With such a configuration, the drum is uniformly humidified by rotating the drum during the ozonolysis process. Thereby, decomposition | disassembly of the ozone in a drum can be accelerated | stimulated uniformly.

  When it is set as said structure, an ozone treatment apparatus may be set as the structure further equipped with the rotation selection operation part which receives operation which selects whether the said drum is rotated.

  With such a configuration, when deodorizing or sterilizing a processing object that is not desired to be agitated by rotation of the drum, the rotation selection operation unit is operated so as not to rotate the drum. can do. Thereby, it is possible to prevent problems such as pain from occurring on the object to be processed due to the rotation of the drum.

  The ozone treatment apparatus according to this aspect may further include a heating unit that heats the housing unit. In this case, the control unit operates the heating unit together with the mist generation unit in the ozone decomposition step.

  According to said structure, since decomposition | disassembly of ozone is greatly accelerated | stimulated compared with the structure which only humidifies the inside of a accommodating part, time until extraction of a process target object is attained can be shortened. Moreover, since the time until the processing object can be taken out can be shortened compared to the configuration in which only the heating in the container is performed, the entire ozonolysis process is compared with the configuration in which only the heating is performed. Power consumption can be reduced.

  When it is set as said structure, an ozone treatment apparatus may be set as the structure further provided with the heating selection operation part which receives operation which selects whether the said accommodating part is heated.

  With such a configuration, when deodorizing or sterilizing a heat-sensitive processing object, it is possible to set the interior of the storage unit not to be heated by operating the heating selection operation unit. Therefore, it is possible to prevent the processing object that is weak against heat from being damaged.

  According to the present invention, ozone that can reduce power consumption and shorten the time from when the supply of ozone is stopped until the processing object can be taken out even when the processing object is vulnerable to heat. A processing device can be provided.

  Hereinafter, a drum type washing / drying machine 1 which is an embodiment of the ozone treatment apparatus of the present invention will be described with reference to the drawings.

  FIG. 1 is a side cross-sectional view showing the configuration of the drum-type washing / drying machine 1.

  The drum-type washing / drying machine 1 includes a housing 10 that forms an appearance. The front surface 10a of the housing 10 is inclined from the central portion to the upper portion, and the laundry inlet 11 is formed on the inclined surface. The insertion port 11 is covered with a door 12 that can be freely opened and closed.

  The outer tub 20 is elastically supported by a plurality of dampers 21 in the housing 10. A drum 22 is rotatably disposed in the outer tub 20. The outer tub 20 and the drum 22 constitute the housing portion of the present invention. The outer tub 20 and the drum 22 are inclined with respect to the horizontal direction so that the rear surface side becomes lower. As a result, the drum 22 rotates around the tilt axis tilted with respect to the horizontal direction. The inclination angle of the outer tub 20 and the drum 22 can be about 10 to 20 degrees. The opening 20a on the front surface of the outer tub 20 and the opening 22a on the front surface of the drum 22 are opposed to the charging port 11, and both the charging port 11 is closed by the door 12. A large number of dewatering holes 22 b are formed on the inner peripheral surface of the drum 22. Further, three baffles 23 are provided on the inner peripheral surface of the drum 22 at substantially equal intervals in the circumferential direction.

  In the upper part of the outer tub 20, an air vent part 20b composed of a plurality of small holes is provided. For example, when the door 12 is closed, a part of the air in the outer tub 20 is pushed by the door 12 and escapes from the air vent 20b to the outside. Thereby, the door 12 is smoothly closed. The air vent 20b corresponds to the hole of the present invention. In the state where the air vent 20b is present but the door 12 is closed, the inside of the outer tub 20 is almost sealed.

  A drive motor 30 that generates torque for driving the drum 22 is disposed behind the outer tub 20. The drive motor 30 is, for example, an outer rotor type DC brushless motor. The drive motor 30 rotates the drum 22 at a rotational speed at which the centrifugal force applied to the laundry in the drum 22 is smaller than gravity during the washing process and the rinsing process. On the other hand, during the dehydration process, the drive motor 30 rotates the drum 22 at a rotation speed at which the centrifugal force applied to the laundry in the drum 22 is much greater than the gravity.

  A drain port 20 c is formed at the bottom of the outer tub 20. A drain valve 40 is provided at the drain port 20c. The drain valve 40 is connected to the drain hose 41. When the drain valve 40 is opened, the water stored in the outer tub 20 is discharged to the outside through the drain hose 41.

  A drying unit 50 is disposed outside the outer tub 20. The drying unit 50 includes a circulation air passage 51, a circulation blower 52, and a heater 53. The inlet 51 a of the circulation air passage 51 is provided at the lower rear surface of the outer tub 20, and the exhaust outlet 51 b of the circulation air passage 51 is provided at the upper front of the outer tub 20. The circulation blower 52 circulates drying air for drying the laundry between the outer tub 20 and the circulation air passage 51. The heater 53 heats the drying air. The circulation air passage 51 includes a vertical air passage 51c extending up and down along the rear surface of the outer tub 20. The vertical air passage 51c functions as a dehumidifying unit. That is, water is flowed from above into the vertical air passage 51c, and moisture is taken from the laundry in the drum 22 and the dry air discharged from the outer tub 20 exchanges heat with water flowing through the vertical air passage 51c. I do. Thereby, moisture is removed from the dry wind. The circulation blower 52 corresponds to the wind generating part of the present invention.

  An ozone generator 61 is disposed above the outer tub 20. The ozone generator 61 is a discharge-type ozone generator that generates a discharge such as a corona discharge or a silent discharge between a pair of electrodes, and generates ozone from the air passed between the pair of electrodes. The ozone generator 61 is connected to the inlet side of the circulation blower 52 in the circulation air passage 51 through the ozone supply pipe 62. When the circulation blower 52 rotates, the suction side becomes negative pressure, so that the ozone generated by the ozone generator 61 is sucked into the circulation blower 52. The sucked ozone is mixed with dry air and supplied into the drum 22. The ozone generator 61 may be a system other than the discharge system, for example, an ultraviolet ozone generator. The ozone generator 61 corresponds to the ozone generator of the present invention.

  An ultrasonic humidifier 70 is further disposed above the outer tub 20. The ultrasonic humidifier 70 generates mist. The generated mist is supplied into the outer tub 20 and the drum 22 through the mist supply pipe 71. The ultrasonic humidifier 70 corresponds to the mist generating part of the present invention.

  A water supply valve 80 is disposed at the upper rear part in the housing 10. The water supply valve 80 is connected to a water tap. The water supply valve 80 is a triple valve and includes a first valve 81, a second valve 82, and a third valve 83. The first valve 81 is connected to the rear portion of the outer tub 20 via the first hose 84. In the water supply process, when the first valve 81 is opened, tap water is supplied into the outer tub 20 through the first hose 84. The second valve 82 is connected to the upper part of the vertical air passage 51 c via the second hose 85. In the drying step, when the second valve 82 is opened, tap water is supplied to the vertical air passage 51c through the second hose 85. As described above, the water supplied to the vertical air passage 51c is used for dehumidification of the dry air. The third valve 83 is connected to the ultrasonic humidifier 70 via the third hose 86. When the ultrasonic humidifier 70 needs to be replenished with water, the third valve 83 is opened. When the third valve 83 is opened, tap water is supplied to the ultrasonic humidifier 70 through the third hose 86.

  FIG. 2 is a side view showing the configuration of the ultrasonic humidifier 70, in which a water storage tank 701 is shown in cross section.

The ultrasonic humidifier 70 includes a water storage tank 701 in which water is stored. In the water storage tank 701, an intake port 701a is formed on the rear surface, a discharge port 701b is formed on the front surface, and a water supply port 701c is formed on the upper surface. The water storage tank 701 is provided with an ultrasonic oscillator 702 on the bottom surface and a water level detector 703 on the front surface. An intake pipe 704 is connected to the intake port 701a. The intake pipe 704 is provided with an intake fan 705. The discharge port 701 b is connected to the mist supply pipe 71. The water supply port 701c is connected to the third hose 86. The water level detector 703 detects the upper limit water level and the lower limit water level. When the lower limit water level is detected by the water level detector 703, the third valve 83 is opened and water is supplied into the water storage tank 701 through the third hose 86. When the water level detector 703 detects the upper limit water, the third valve 83 is closed and the supply of water is stopped. The ultrasonic oscillator 702 and the intake fan 705 operate in a state where water is stored in the water storage tank 701. When the ultrasonic oscillator 702 operates, mist is generated from the accumulated water by ultrasonic vibration. When the intake fan 705 operates, air is sucked from the intake pipe 704, and the sucked air is introduced into the water storage tank 701. The introduced air takes in mist and is discharged from the discharge port 701b. The air that has taken in the mist is supplied into the drum 22 through the mist supply pipe 71 and the outer tub 20.

  FIG. 3 is a block diagram showing the configuration of the drum type washing / drying machine 1.

  The drum-type washing / drying machine 1 includes a control unit 101, a storage unit 102, an operation unit 103, a water level sensor 104, and a door lock device 105 in addition to the above-described configuration.

  The operation unit 103 includes a power button 103a, a start button 103b, a course selection button 103c, and an air wash button 103d. The power button 103 a is a button for turning on and off the power of the drum type washing and drying machine 1. The start button 103b is a button for starting operation. The course selection button 103c is a button for selecting an arbitrary driving course from a plurality of driving courses related to the washing operation, the washing / drying operation, and the drying operation. The air wash button 103d is a button for selecting an air wash course provided separately from an operation course related to a washing operation or the like. The operation of the air wash course will be described in detail later. The operation unit 103 outputs an input signal corresponding to the button operated by the user to the control unit 101. The operation unit 103 corresponds to a rotation selection operation unit of the present invention.

  The water level sensor 104 detects the water level in the outer tub 20 and outputs a water level detection signal corresponding to the detected water level to the control unit 101.

  The door lock device 105 locks and unlocks the door 12 in accordance with a control signal from the control unit 101.

  The storage unit 102 includes an EEPROM, a RAM, and the like. The storage unit 102 stores a program for executing a washing operation of various washing operation courses and a program for executing an operation of an air wash course. The storage unit 102 stores various parameters and various control flags used for executing these programs.

  Based on the signals stored in the storage unit 102 based on the signals from the operation unit 103, the water level sensor 104, etc., the control unit 101 follows the drive motor 30, the water supply valve 80, the drain valve 40, the circulation blower 52, the heater 53, Each load of the ozone generator 61, the ultrasonic humidifier 70, the door lock device 105, etc. is controlled.

  The drum-type washing / drying machine 1 performs a washing operation, a washing / drying operation, or a drying operation of various operation courses based on a user's selection operation by the course selection button 103c. The washing operation is an operation in which only washing is performed, and a washing process, an intermediate dehydration process, a rinsing process, and a final dehydration process are sequentially performed. The washing and drying operation is an operation in which washing to drying is continuously performed, and the drying step is executed following the final dehydration step. The drying operation is an operation in which only drying is performed, and only the drying process is executed.

  In the washing step and the rinsing step, the centrifugal force acting on the laundry in the drum 22 is exerted on the drum 22 in a state where water is accumulated in the outer tub 20 to a predetermined water level that does not reach the lower edge of the inlet 11. Rotate clockwise and counterclockwise at a rotational speed smaller than gravity. The laundry in the drum 22 is beaten against the inner peripheral surface of the drum 22 by being scraped and dropped by the baffle 23. As a result, the laundry is washed or rinsed.

  In the intermediate dewatering process and the final dewatering process, the drum 22 rotates in one direction at a rotation speed at which the centrifugal force acting on the laundry in the drum 22 is much greater than gravity. By the action of centrifugal force, the laundry is pressed against the inner peripheral surface of the drum 22 and dehydrated.

  In the drying process, the drying air heated by the heater 53 circulates between the circulation air passage 51 and the outer tub 20. Further, similarly to the washing process and the rinsing process, the drum 22 rotates clockwise and counterclockwise. The laundry in the drum 22 comes into contact with the drying air introduced into the drum 22 while being stirred by the baffle 23. The dry air deprived of moisture from the laundry by contact is dehumidified in the vertical air passage 51 c, heated again by the heater 53, and introduced into the drum 22. In this way, the laundry is dried. When drying laundry that is not desired to be stirred, the drum 22 does not rotate in the drying process.

  Furthermore, the drum-type washing / drying machine 1 performs deodorization, sterilization, and the like of objects to be processed such as clothes, bags, shoes, etc. by ozone based on the operation of the air wash button 103d by the user, separately from the washing operation and the like. Operate the air wash course.

  The operation of the air wash course is performed by supplying the ozone generated by the ozone generator 61 into the drum 22 to deodorize and sterilize the object to be treated, and the drum generation process. And an ozone decomposing step of eliminating ozone remaining in 22 by decomposition. After the ozone concentration in the drum 22 is sufficiently lowered by the ozone decomposing step, the air wash course is finished, the door 12 is unlocked, and the processing object can be taken out.

  In order to shorten the time from the completion of the ozone generation process until the processing object can be taken out (hereinafter referred to as “takeout waiting time”), it is necessary to promote the decomposition of ozone.

It is known that the decomposition of ozone is accelerated as the ambient temperature increases. Therefore, for example, a configuration may be adopted in which the air heated by the heater is supplied into the drum 22 to heat the inside of the drum 22 and promote decomposition of ozone. However, when it is configured to promote the decomposition of ozone by heating, relatively large electric power is easily consumed. Further, such a configuration is difficult to apply when the object to be processed is vulnerable to heat.
Therefore, the inventors of the present application have considered a method for promoting the decomposition of ozone under other conditions instead of heating, and as a result, the ozone decomposition is promoted by humidifying the inside of the drum 22 where ozone remains. I found it.

  FIG. 4A is a diagram showing the change over time in the ozone concentration in the drum 22 when the ozone generation process is completed and then left naturally. FIGS. 4B and 4C are diagrams showing the change over time in the ozone concentration in the drum 22 when the inside of the drum 22 is humidified after the ozone generation step is completed. FIG. 4B shows the change over time in ozone concentration when the mist is supplied into the drum 22 and the humidity in the drum 22 is increased to nearly 100%. FIG. 4C shows the mist in the drum 22. Is shown, and a change with time in ozone concentration when the humidity in the drum 22 is increased to approximately 80% is shown. 4A to 4C, after the ozone generation step is executed in a state where the ozone concentration in the drum 22 exceeds 20 ppm, the supply of ozone is stopped and the ozone concentration in the drum 22 becomes 0.09 ppm. 4 is a graph plotting the ozone concentration, temperature and humidity in the drum 22.

  In the experiments of FIGS. 4 (a) to 4 (c), the ozone concentration in the ozone generation process is the ozone concentration in the actual air wash course operation so that the effect of promoting the decomposition of ozone by humidification can be easily confirmed. Is set to a higher value.

  As shown in FIGS. 4B and 4C, when the inside of the drum 22 is humidified, it is apparent that the supply of ozone is stopped as compared with the case of natural standing shown in FIG. It can be seen that the time until the ozone concentration decreases to 0.09% is shortened, and that ozone decomposition is promoted when the inside of the drum 22 is humidified.

The reason why the ozone concentration decreases due to humidification is not clear, but it is probably caused by the fact that ozone gas is dissolved in fine water (mist) during humidification or decomposed by reaction. It is similar to the reaction mechanism of ozone in water, and the following reactions are considered to be progressing.
O ₃ + OH ⁻ → O ₂ ⁻ + HO ₂
O ₃ + HO ₂ → 2O ₂ + OH
O ₃ + OH → O ₂ + HO ₂
2HO ₂ → O ₃ + H ₂ O
HO ₂ + OH → O ₂ + H ₂ O

  In the drum-type washing / drying machine 1 of the present embodiment, the ozone decomposition process in the air wash course supplies mist into the drum 22 based on the new knowledge that the decomposition of ozone is promoted by humidification. It comprises a humidifying process for humidifying, and a dehumidifying process for removing mist from the drum 22 and reducing the humidity in the drum 22.

  Specific control contents in the operation of the air wash course will be described below.

  FIG. 5 is a flowchart showing a control process in the air wash course. When the air wash course is selected by operating the air wash button 103d and then the start button 103b is operated, the control unit 101 starts operation of the air wash course. Note that the user sets whether to rotate the drum 22 in the air wash course according to the number of times the air wash button 103d is pressed. When a user places a processing object that is not desired to be stirred by rotation of the drum 22, such as a bag, shoes, clothes that are easily deformed, etc., in the drum 22, the user sets the drum 22 not to rotate.

  When the operation is started, the control unit 101 first executes a drain trap water supply process (S11). In the drain trap water supply process, the control unit 101 opens the first valve 81 with the drain valve 40 open, and supplies water into the outer tub 20. A drain trap for storing water is provided downstream of the drain valve 40, and the water supplied to the outer tub 20 passes through the drain valve 40 and is stored in the drain trap. An overflow hose extending from an overflow port provided in the outer tub 20 is connected between the drain valve 40 and the drain trap. Since the water trap is used in the drain trap, ozone supplied to the drum 22 is prevented from leaking out of the machine through the overflow hose and the drain hose 41 in the ozone generation step.

  When a predetermined water supply time, for example, 1 minute 20 seconds elapses, the control unit 101 closes the first valve 81 and ends the drain trap water supply process.

  Next, the control unit 101 determines whether or not the setting for rotating the drum 22 is made (S12). If the setting to rotate the drum 22 is made (S12: YES), the control unit 101 starts the rotation of the drum 22 (S13), and then proceeds to the ozone generation process (S14). If it is not set to rotate (S12: NO), the process proceeds to the ozone generation step without rotating the drum 22 (S14).

  In the ozone generation step, the control unit 101 operates the ozone generator 61 after operating the circulation blower 52. Ozone generated in the ozone generator 61 is mixed with dry air and supplied into the drum 22. Ozone comes into contact with the processing object in the drum 22, and the processing object is deodorized and sterilized. When a predetermined ozone generation time, for example, 10 minutes elapses, the controller 101 stops the ozone generator 61 and the circulation blower 52 and ends the ozone generation process.

  Next, the control part 101 performs an ozonolysis process. First, the control unit 101 executes a humidification process (S15), and subsequently executes a dehumidification process (S16). When the drum 22 is rotated in step S13, the rotation of the drum 22 is maintained also in the ozone decomposition process.

  FIG. 6 is a flowchart showing a control process in the humidification step.

  In the humidification process, the control unit 101 operates the ultrasonic humidifier 70 (S101). Mist generated in the ultrasonic humidifier 70 is supplied into the outer tub 20 and the drum 22 through the mist supply pipe 71, and the drum 22 is humidified. Due to the humidification, the humidity in the drum 22 rises from a target value of 80% to a value of about 100%, for example. When a predetermined humidification time, for example, 8 minutes elapses (S102: YES), the control unit 101 stops the ultrasonic humidifier 70, ends the humidification process, and proceeds to the dehumidification process.

  Returning to FIG. 5, in the dehumidifying step, the control unit 101 operates the circulation blower 52. Wind is generated in the outer tub 20 and the drum 22, and the mist is gradually discharged out of the outer tub 20 through the air vent 20 b. Thereby, the humidity in the drum 22 gradually decreases. When a predetermined dehumidifying time, for example, 2 minutes elapses, the control unit 101 stops the circulation blower 52 and ends the dehumidifying process.

  During the ozone decomposition process, the ozone in the drum 22 is decomposed. At this time, since the inside of the drum 22 is humidified in the humidification step, decomposition of ozone is promoted. When the drum 22 is set to rotate, the drum 22 rotates during the ozone decomposing step, so that the inside of the drum 22 is uniformly humidified and the decomposition of ozone in the drum 22 is promoted uniformly. Thus, when the ozone decomposition step is completed, the ozone concentration in the drum 22 is lowered to a concentration at which the object to be treated can be taken out.

  When the ozonolysis process ends, the control unit 101 determines whether or not the drum 22 is rotating (S17). If the drum 22 is not rotating (S17: NO), the operation of the air wash course is ended as it is. The control unit 101 unlocks the door 12 and enables the processing object to be taken out. When the drum 22 is rotating (S17: YES), the control unit 101 stops the operation of the air wash course after stopping the drum 22 (S18).

  In addition, when the drum 22 rotates in the operation of the air wash course, the drum 22 may rotate continuously or intermittently. When the drum 22 rotates intermittently, the operation time may be longer than the stop time, or the stop time may be longer than the operation time. Further, the drum 22 may rotate intermittently in one direction, or may rotate so that clockwise and counterclockwise are mixed.

  As described above, according to the present embodiment, mist is supplied into the drum 22 in the ozonolysis step, and the inside of the drum 22 is humidified. Thereby, decomposition | disassembly of the ozone which remains in the drum 22 is accelerated | stimulated. Therefore, the waiting time for taking out the processing object can be shortened. In addition, since the power consumption required for humidification by the ultrasonic humidifier 70 can be reduced as compared with the power consumption required for heating by the heater, it is possible to promote decomposition of residual ozone while suppressing power consumption. Further, even when the object to be treated is weak against heat, it is possible to promote the decomposition of residual ozone.

  Further, according to the above embodiment, after the mist is discharged out of the outer tub 20 and the humidity in the drum 22 is lowered, the operation of the air wash course is ended. Thereby, it can prevent that a user puts a hand in the drum 22 with high humidity and feels discomfort.

  Furthermore, according to the above-described embodiment, the drum 22 is uniformly humidified by rotating the drum 22 during the ozonolysis process. Thereby, decomposition | disassembly of the ozone in the drum 22 can be accelerated | stimulated uniformly.

  Furthermore, according to the above embodiment, when deodorizing or sterilizing a processing object that is not desired to be agitated by the rotation of the drum 22, by operating the air wash button 103d of the operation unit 103, The drum 22 can be set not to rotate. Thereby, it is possible to prevent problems such as pain from occurring on the object to be processed due to the rotation of the drum 22.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and the like, and various modifications can be made to the embodiments of the present invention in addition to the above. is there.

<Modification 1>
In the above embodiment, the ultrasonic humidifier 70 is used to supply the mist into the drum 22. On the other hand, in this modified example, the mist nozzle 90 is used for supplying the mist into the drum 22.

  FIG. 7 is a side cross-sectional view showing the configuration of the drum-type washing / drying machine 1 according to this modification. In the present modification, a mist nozzle 90 is disposed at the rear upper part of the outer tub 20, and the mist nozzle 90 is connected to the third valve 83 via the third hose 86. When the third valve 83 is opened, tap water is supplied to the mist nozzle 90. The mist nozzle 90 converts the supplied water into mist, and sprays the converted mist into the outer tub 20 and the drum 22. The mist nozzle 90 corresponds to the mist generating part of the present invention.

  FIG. 8 is a flowchart showing the control process in the humidification process according to this modification. In this modified example, the control process in the humidification process in the operation of the air wash course is different from the above embodiment. Hereinafter, the control process of a humidification process is demonstrated with reference to FIG.

  If it progresses to a humidification process (S15), the control part 101 will open the 3rd valve | bulb 83 (S201). Mist is sprayed from the mist nozzle 90 into the outer tub 20 and the drum 22. Thereby, the inside of the drum 22 is humidified.

  When a predetermined spraying time, for example, 2 minutes elapses (S202: YES), the control unit 101 closes the third valve 83 (S203). Thereby, spraying of mist stops. Since the amount of mist supplied per unit time by the mist nozzle 90 is larger than the amount of mist supplied per unit time by the ultrasonic humidifier 70 of the above-described embodiment, the humidity in the drum 22 can be reduced to the target in a short time. From 80% to 100%. Therefore, the control unit 101 stops the mist spraying at an early stage, and then waits until the humidification time, for example, 10 minutes elapses from the start of the humidification process. When the humidification time has elapsed (S204: YES), the control unit 101 ends the humidification process and proceeds to the dehumidification process.

  According to the configuration of this modification, the same operational effects as those of the above embodiment can be obtained.

  In particular, in this modified example, the mist nozzle 90 is used to generate mist, and the consumed electric power is electric power for opening and closing the third valve 83 that supplies water to the mist nozzle 90. For this reason, compared with the case where the ultrasonic humidifier 70 is operated, power consumption can be suppressed.

<Modification 2>
In the first modification, the mist nozzle 90 is used for supplying the mist into the drum 22. On the other hand, in this modification, the structure which produces | generates mist by scattering the water stored in the outer tank 20 by rotation of the drum 22 is taken. In this modified example, the drum 22 corresponds to the mist generating unit of the present invention.

  FIG. 9 is a side cross-sectional view showing the configuration of the drum-type washing / drying machine 1 according to this modification. In the present modified example, as described above, the ultrasonic humidifier 70 and the mist nozzle 90 are not used, so the water supply valve 80 is a double valve including the first valve 81 and the second valve 82.

  FIG. 10 is a flowchart showing a control process in the air wash course according to this modification. In the control process of this modification example shown in FIG. 10, the process of step S12 and the process of step S17 executed in the control process of the above-described embodiment shown in FIG. 5 are not executed. That is, when the drain trap water supply process is completed (S11), the control unit 101 rotates the drum 22 (S13) and proceeds to the ozone generation process (S14). Further, when the dehumidifying process constituting the ozonolysis process ends (S16), the control unit 101 stops the drum 22 (S18).

  FIG. 11 is a flowchart showing the control process in the humidification process according to this modification.

  If it progresses to a humidification process (S15), the control part 101 will stop the rotating drum 22 once (S301). Next, the control unit 101 opens the first valve 81 (S302). Thereby, tap water is supplied into the outer tub 20. The control unit 101 determines whether or not the water level in the outer tub 20 has reached a splatterable water level (S303). As shown in FIG. 9, the possible water level is set such that the water surface slightly touches the outer peripheral surface of the drum 22. When the water level in the outer tub 20 reaches the splatterable water level (S303: YES), the control unit 101 closes the first valve 81 (S304). Thereby, the water supply to the outer tank 20 stops.

  The control unit 101 rotates the drum 22 again (S305). The outer peripheral surface of the drum 22 has slight irregularities such that the outer edge of the dewatering hole 22b slightly protrudes outside in processing. For this reason, when the water surface is swept by the outer peripheral surface of the drum 22 by rotating the drum 22, water is scattered and mist is generated. The drum 22 is humidified by the generated mist. Similar to the above-described embodiment, the humidity in the drum 22 increases, for example, from a target value of 80% to about 100% by humidification. When a predetermined humidification time, for example, 8 minutes elapses (S306: YES), the control unit 101 opens the drain valve 40 (S307) and ends the humidification process. Although the rotation of the drum 22 is continued, the water level in the outer tub 20 is lowered and the outer peripheral surface of the drum 22 does not touch the water surface, so that the generation of mist stops.

  According to the configuration of the present modified example, the same effects as those of the above-described embodiment can be obtained except for the effect that it is possible to prevent the processing object that is not desired to be stirred by the rotation of the drum 22 from occurring. Can do.

  In particular, in this modified example, since the configuration for generating mist by the rotation of the drum 22 is adopted, a dedicated device for generating mist such as the ultrasonic humidifier 70 is not required, and the increase in cost can be suppressed.

<Other changes>
In the configuration of the above embodiment, Modification 1 and Modification 2, when deodorizing or sterilizing a processing object that is not weak against heat, in the humidification step, the inside of the drum 22 is added in addition to humidification. A configuration for heating may be added. In this case, a switch button is provided on the operation unit 103, and whether or not the inside of the drum 22 is heated is set by the switch button. The user performs setting for heating the inside of the drum 22 when performing deodorization, sterilization, or the like of the processing object that is not weak against heat.

  FIG. 12 is a flowchart of the control process in the humidification process when a configuration for heating the inside of the drum 22 is added to the configuration of the above embodiment. In the control process shown in FIG. 12, the processes in steps S111 to S114 are added to the control process shown in FIG.

  In the present modification, the control unit 101 determines whether or not the setting for heating the inside of the drum 22 has been made after operating the ultrasonic humidifier 70 (S111). When the setting for heating the inside of the drum 22 is made (S111: YES), the control unit 101 operates the heater 53 and the circulation blower 52 (S112). The wind heated by the heater 53 is supplied into the drum 22 and the inside of the drum 22 is heated. Thereby, decomposition of ozone remaining in the drum 22 is promoted not only by humidification but also by heating. Therefore, decomposition of ozone is greatly promoted.

  When a predetermined humidification / heating time elapses (S113: YES), the control unit 101 stops the heater 53 and the circulation blower 52 (S114). Furthermore, the control unit 101 stops the ultrasonic humidifier 70 (S103) and ends the humidification process. As ozone decomposition is greatly accelerated by humidification and heating, the ozone concentration in the drum 22 decreases more quickly than in the case of only humidification. For this reason, the humidification / heating time is shorter than the humidification time.

  FIG. 13 is a flowchart of the control process in the humidification process when a configuration for heating the inside of the drum 22 is added to the configuration of the first modification. In the control process shown in FIG. 13, the processes of steps S211 to S216 are added to the control process shown in FIG.

  In the present modification example, the control unit 101 determines whether or not the setting for heating the inside of the drum 22 has been made after opening the third valve 83 (S211). When the setting for heating the inside of the drum 22 is made (S211: YES), the control unit 101 operates the heater 53 and the circulation blower 52 (S212). By heating the inside of the drum 22, the decomposition of ozone remaining in the drum 22 is greatly promoted.

  When the spraying time has elapsed (S213: YES), the controller 101 closes the third valve 83 (S214). Further, when the humidification / heating time has elapsed (S215: YES), the control unit 101 stops the heater 53 and the circulation blower 52 (S216), and ends the humidification process.

  FIG. 14 is a flowchart of the control process in the humidification process when a configuration for heating the inside of the drum 22 is added to the configuration of the second modification. In the control process shown in FIG. 14, the processes in steps S311 to S314 are added to the control process shown in FIG.

  In this modification, the control unit 101 determines whether or not the setting for heating the inside of the drum 22 is made after the drum 22 is rotated again (S311). When the setting for heating the inside of the drum 22 is made (S311: YES), the control unit 101 operates the heater 53 and the circulation blower 52 (S312). By heating the inside of the drum 22, the decomposition of ozone remaining in the drum 22 is greatly promoted. When the humidification / heating time has elapsed (S313: YES), the control unit 101 stops the heater 53 and the circulation blower 52 (S314). Furthermore, the control unit 101 opens the drain valve 40 (S307) and ends the humidification process.

  With these modified examples, the decomposition of ozone is greatly promoted as compared with the configuration in which only the humidification in the drum 22 is performed, so that the waiting time for taking out the processing object can be shortened. Further, since the waiting time for taking out can be shortened compared to the configuration in which the drum 22 is heated, the power consumption of the entire ozonolysis process can be suppressed as compared with the configuration in which heating is performed only.

  Further, with the configuration of these modified examples, when deodorizing or sterilizing a processing object that is weak against heat, the operation of the operation unit 103 can be set so that the interior of the drum 22 is not heated. Therefore, it is possible to prevent the processing object that is weak against heat from being damaged by heating.

  In the modified examples shown in FIGS. 12 to 14, the heater 53 corresponds to the heating unit of the present invention, and the operation unit 103 corresponds to the heating selection operation unit of the present invention.

  In the above embodiment, the ozone generation process and the ozone decomposition process are executed in the operation of the air wash course provided separately from the washing operation, the washing drying operation, and the drying operation. However, the ozone generation step and the ozonolysis step may be performed after the drying step in the laundry drying operation or the drying operation.

  Furthermore, in the above-described embodiment, the drum 22 rotates around the tilt axis tilted with respect to the horizontal direction. However, the drum-type washing / drying machine 1 may be configured such that the drum 22 rotates around the horizontal axis.

  Furthermore, in the said embodiment, although the drum type washing-drying machine which has the function to deodorize, disinfect, etc. of clothing by ozone was illustrated, this invention is not limited to a drum-type washing dryer, but clothing by ozone The present invention can also be applied to a drum-type washing machine, a fully automatic washing machine, a fully automatic washing / drying machine, a clothes drying machine, etc. having a function of deodorizing, sterilizing, etc. Furthermore, the present invention provides a shoe washing machine having a function of deodorizing and sterilizing shoes with ozone in addition to a washing function, a suit refresher for deodorizing and sterilizing a suit with ozone, etc. The present invention can be applied to various ozone treatment apparatuses that deodorize and sterilize processing objects.
