  In conventional clothes dryers, those shown in Patent Document 1 and Patent Document 2 use ozone, and ozone can decompose most of malodorous components in the air. As a result, these clothes The dryer had an air cleaning function, but it was not even recognized. Therefore, conventionally, it has not been considered to effectively use this air cleaning function, and it has not been at a technical level that can be used.

  Accordingly, the present invention has been made to solve such problems, and an object thereof is to provide a multifunctional clothes dryer that can also be used as an air purifier.

  In order to achieve the above-described object, the present invention generates a drying chamber having clothes that can be opened and closed and housing clothes, and hot air that has an inlet and is supplied to the drying chamber. A hot air generating mechanism that generates ozone and an ozone generating mechanism that generates ozone to be supplied into the drying chamber, and a control unit thereof, and the control unit does not drive the heating means of the hot air generating mechanism, and the hot air generating mechanism It has an air purifying mode for controlling to operate an air purifying function for driving the air blowing means and the ozone generating mechanism.

  Furthermore, it has clothing detection means for detecting the presence or absence of clothing in the drying chamber, and the control unit activates the air cleaning function when clothing is not detected by the clothing detection means.

  Further, the control unit activates an air cleaning function in which the ozone concentration is higher than that in the deodorizing and drying of clothes in the air cleaning mode.

  In addition, air pollution detection means for detecting the dirt of the air outside the machine sucked from the intake port is provided, and the control unit detects that the air dirt concentration exceeds a predetermined concentration by the air dirt detection means. The air purifying function is activated when the air purifier is activated.

  The apparatus further comprises ozone concentration detecting means for detecting the ozone concentration in the drying chamber, and the controller controls the amount of air blown into the drying chamber based on the ozone concentration detected by the ozone concentration detecting means to obtain the ozone concentration. The deodorizing and drying is controlled within a predetermined range higher than that at the time of deodorizing and drying.

  In addition, an ozone concentration detection unit that detects an ozone concentration in the drying chamber is provided, and the control unit controls the applied voltage for generating ozone based on the ozone concentration detected by the ozone concentration detection unit, thereby adjusting the ozone concentration. Control is performed within a predetermined range that is higher than that when clothes are deodorized and dried.

  According to the present invention, since the heating means of the hot air generating mechanism is not driven, the air purifying mode for controlling the air purifying function for driving the air blowing means and the ozone generating mechanism of the hot air generating mechanism is operated. A multifunctional clothes dryer that can also be used as an air purifier is obtained. Further, since the heating means is not driven, it is possible to prevent hot air from being blown into the room and to suppress wasteful power consumption.

  Furthermore, by operating the air cleaning function when no clothing is detected by the clothing detection means, the air in the room in which the clothing dryer is installed can be cleaned without ozone being used to deodorize the clothing, and Since the air purifying function is not activated while the clothes are left in the drying chamber due to a user's inadvertent mistake or the like, a multifunctional clothes dryer that can be used practically as an air purifier can be obtained.

  In addition, a multifunctional clothes dryer that can be used effectively as an air cleaner can be obtained by operating an air cleaning function with a higher ozone concentration than when deodorizing and drying clothes in the air cleaning mode.

  In addition, when the air dirt detecting means detects that the air dirt concentration exceeds a predetermined concentration, the air cleaning function is activated, so that the air in the room where the clothes dryer is installed is not dirty. Since the air cleaning function does not operate and the air cleaning function is not activated when the air in the room is cleaned by the operation of the air cleaning function, unnecessary operation is suppressed and there is an energy saving effect.

  In addition, by controlling the amount of air blown into the drying chamber based on the ozone concentration in the drying chamber detected by the ozone concentration detection means, the ozone concentration is controlled to be within a predetermined range higher than that at the time of deodorizing and drying the clothing. Since the indoor ozone concentration is relatively increased when the amount of air blown into the drying chamber is decreased, energy-saving operation is possible.

  In addition, by controlling the applied voltage for generating ozone based on the ozone concentration detected by the ozone concentration detecting means and controlling the ozone concentration within a predetermined range higher than that when clothes are deodorized and dried, Since the ozone concentration is substantially increased by increasing the ozone generation applied voltage, a multifunctional clothes dryer that can be effectively used as an air cleaner can be obtained. Furthermore, by using together with the above air volume control, it becomes easy to control the ozone concentration within a predetermined range that is higher than that when clothes are deodorized and dried.

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

  FIG. 1 is an external perspective view of a suit deodorizing dryer as an embodiment of a clothes dryer according to the present invention, and FIGS. 2A, 2B, and 2C are a plan view, a front view, a side view, and FIG. 3 is a partially cutaway front view showing the internal configuration, and FIG. 4 is a system configuration diagram.

  This suit deodorization dryer is suitable for installation in each room of a business hotel, etc., or for renting it at the front desk according to the needs of the guest. The body 1 formed in a box shape can be opened and closed. There is provided a drying chamber 3 having a door 2 for storing clothes, and a machine chamber 4 arranged to be connected to the lower portion of the drying chamber 3.

  As shown in FIG. 3, the drying chamber 3 has a hanging tool 7 that hangs clothes such as a suit jacket 5 on the hanger 6 so as to be parallel to the door 2 while being suspended. The outer garment 5 is formed in a size having a height, width and depth that can be stored. That is, the height of the suit jacket 5 hung on the hanger 6 is slightly larger than the height, width, and depth. Specifically, the drying chamber 3 preferably has a height of 1000 to 1200 mm, for example, 1100 mm and a width of 600 mm. 650 mm is preferable, for example, 600 mm, and depth is preferably 150 to 300 mm. For example, 150 mm for a suit (front and back trousers and outerwear), and 300 mm for two suits (front and rear trousers and outerwear). It becomes size. The machine room 4 connected to the lower part of the drying room 3 has the same width and depth as the drying room 3.

  As mentioned above, this suit deodorization dryer is thin with a smaller depth direction compared to the width and height directions, and requires only a small installation space in the depth direction. Or it is suitable for lending at the front desk according to the needs of the guests. Further, the door 2 has a handle 2a on one side, and the hinge 2b on the other side opens and closes the entire width direction so that it can be opened and closed smoothly. The door 2 may be double-opened although not shown. Further, as shown in part in FIG. 3, an outer frame that protrudes corresponding to the opening edge of the drying chamber 3 is formed on the inner side of the door 2, and the inner side is a recess corresponding to the opening of the drying chamber 3. Thus, the depth of the drying chamber 3 can be increased without increasing the depth of the main body 1 using this space. As a result, the trouser and the inner surface of the door 2 are in contact with each other even when the suit trousers and the outer garment are hung on the hangers and hung to the rear (back) in the drying chamber 3 so as to become trousers in front. As a result, it is possible to prevent the occurrence of uneven drying and deodorization.

  As described above, the machine room 4 is provided in the lower part of the drying room 3 so as to be connected to the drying room 3, and inside the machine room 4 as shown in FIG. On the right side) is provided with a warm air generating mechanism comprising a blower 8 as a blowing means and a heater 10 as a heating means provided in a duct 9 connected to the outlet, and on the other side (left side in the figure). An ozone generation mechanism including an ozone generator 13 connected to the air pump 11 and its discharge pipe 12 and a control unit power supply board 14 on which a control unit and a power source are mounted are arranged on the back side.

  In this way, by disposing the machine room 4 at the lower part of the drying room 3, it is possible to blow warm air having a lighter specific gravity from the bottom to the top, so that the ventilation drying efficiency is improved and the weight of the blower 8 and the like is increased. Since the machine room 4 in which objects are stored is located at the bottom, the center of gravity is lowered and stability is improved, and the drying room 3 having a height equivalent to the jacket 5 is made higher by the height of the machine room 4 even when placed on the floor. This makes it easier for the user to put on clothes while standing. Further, the hot air generating mechanism is arranged on one side in the width direction in the machine room 4 and the ozone generating mechanism is arranged on the other side, so that the depth is as thin as the drying room 3 connected to the lower part of the drying room 3. The machine room 4 can also arrange the warm air generating mechanism and the ozone generating mechanism in a well-balanced manner.

  The ozone generated by the ozone generator 13 is supplied into the duct 9 immediately after the heater 10 through a pipe 15 and mixed with hot air. The duct 9 is connected to a duct chamber 16 widened in a funnel shape toward the drying chamber 3. Note that ozone from the ozone generator 13 may be directly supplied into the duct chamber 16 and mixed with hot air.

  The top plate of the duct chamber 16 is a bottom plate of the drying chamber 3, in which a plurality of slits and holes are formed, and warm air containing ozone is applied to clothes (such as a suit jacket 5) in the drying chamber 3. The blowout part 17 which blows off uniformly is provided. FIGS. 5A, 5B, and 5C are diagrams showing a configuration example of the blowing portion 17, in which FIG. 5A shows a plurality of lateral slits 17a, and FIG. 5B shows a small round hole. A plurality of slits 17c are formed, and (c) is a plurality of slits 17c in the front-rear direction. In any case, a plurality of slits and holes are formed in accordance with the shape of the body and the sleeves of the suit outerwear 5 suspended in the drying chamber 3 and projected onto the bottom plate. Warm air containing ozone is blown uniformly according to the amount of the fabric to the body and both sleeves of the garment 5, etc., so that drying and deodorization can be performed without damaging the fabric. . Also, warm air or ozone supplied from the bottom of the drying chamber 3 into the drying chamber 3 is suspended in the drying chamber 3 and enters inside from the hem and cuffs of clothing such as a jacket 5 that opens downward. In addition, drying and deodorization can be efficiently performed to the inside of the clothing such as the outer garment 5.

  An intake port 18 is formed in the front surface of the machine room 4, and an intake filter 19 is attached to the intake port 18. Therefore, when the blower 8 is driven, air outside the machine is introduced into the machine room 4 through the intake filter 19 of the intake port 18. The introduced air is sent to the duct 9 by the blower 8, passes through the heater 10 inside the duct 9, is heated to a predetermined temperature (about 70 ° C.), and is sent into the duct chamber 16. Then, the air is blown out from the duct chamber 16 into the drying chamber 3 through the blowing portion 17 as described above. The air sent by the air pump 11 is sent through the ozone generator 13 into the duct 9 (or the duct chamber 16) immediately after the heater 10. At this time, the ability of the ozone generator 13 is such that when the ozone concentration in the drying chamber 3 is deodorizing clothing such as a suit, the ozone generator 13 is, for example, 0.05 to 0.2 ppm. When the applied voltage is adjusted and the air purifying function according to the present invention is activated, the applied voltage of the ozone generator 13 is adjusted so as to be, for example, 0.4 to 1.0 ppm higher than that in the clothes deodorization drying. It is supposed to be. The air inlet 18 may be formed on the side surface of the machine room 4. The intake filter 19 attached to the intake port 18 may be provided with a moisture absorbing material. As described above, by providing the air intake 18 on the front surface or the side surface of the machine room 4, it is possible to constantly cool the control unit, the power supply, and the like mounted on the control unit power supply board 14 with the air outside the machine from the air intake 18. In addition, even if the back surface is placed in close contact with the wall, intake is not hindered. Further, if the intake filter 19 is provided with a hygroscopic material, the air introduced into the ozone generator 13 is dehumidified to a low humidity, so that the amount of ozone generated is stable and the life of the ozone generating element can be extended. Since the air introduced into the hot air generating mechanism is also dehumidified to become low humidity, the dry hot air can be supplied into the drying chamber 3 and the drying efficiency is improved.

  An air dirt sensor Sa (see FIG. 4) is installed between the intake port 18 and the blower 19 as air dirt detection means used when the air cleaning function according to the present invention is operated, and measures the degree of air dirt. Then, by inputting it to the microcomputer mounted on the control unit power supply board 14 described above, the air volume of the blower 8 and the applied voltage of the ozone generator 13 are only measured when the air contamination level is measured and the air cleaning function is activated. It is designed to adjust to the optimum value. As this air dirt sensor Sa, for example, a highly sensitive low concentration detecting a resistance change of a platinum wire coil integrated with a metal oxide semiconductor (sintered body) whose resistance value changes in contact with a gas as a gas concentration. A known hot-wire semiconductor sensor that is a gas detection sensor for detection can be used. The air dirt sensor Sa measures the degree of air dirt in the room where the dryer is installed, and may be provided on the outer wall of the dryer body 1 or the like.

  Further, a leg part 20 for preventing forward tilting is provided at the lower part of the machine room 4, that is, at the lower part of the main body 1. The forward fall prevention leg portion 20 of the present embodiment is a plate-like protrusion over the entire front side, but at least a pair of right and left is sufficient. Thus, by providing the leg part 20 for preventing forward tilt at the lower part of the main body 1, as described above, it is possible to prevent the body from falling forward due to an earthquake or the like even if it is placed on the wall by forming a thin depth. Can do.

  On the other hand, an exhaust port 21 is formed on one side of the upper front surface of the drying chamber 3, and an ozone removal filter 22 that removes excess ozone by decomposing or adsorbing it is attached to the exhaust port 21. ing. Thus, by arranging the exhaust port 21 in the upper part of the drying chamber 3, exhaust can be efficiently performed using natural exhaust due to rising warm air. The air obtained by deodorizing and drying clothes (such as the suit jacket 5) in the drying chamber 3 passes through the upper ozone removing filter 22 and is discharged from the exhaust port 21 to the outside of the apparatus. At this time, the ozone removal filter 22 decomposes or adsorbs excess ozone, lowers the ozone concentration to 0.1 ppm or less and releases it to the outside of the apparatus, so there is no influence on the human body. Note that the ozone removal capability of the ozone removal filter 22 is configured so that the ozone concentration can be reduced to 0.1 ppm or less even when the ozone concentration at the time of activation of the air cleaning function is high.

  Further, in the central portion of the upper front surface of the drying chamber 3, an air purifier that is connected to the control unit power supply board 14 described above and operates the air purifying function according to the present invention in addition to the operation start, stop, and operation time setting. An operation panel 23 provided with buttons and the like for selecting and operating the mode and the normal clothing deodorization drying mode is disposed. Thus, by arranging the operation panel 23 at the upper front of the drying chamber 3, the width of the drying chamber 3 can be used more effectively than the one disposed on the front side of the drying chamber 3 and the like. Since the operation panel 23 is above the clothing (such as the suit jacket 5), visibility and operability are improved.

  FIG. 6 is a diagram specifically showing the operation panel 23, and the silent operation button 23a is not directly related to the present invention, but the standard operation in which the rotational speed of the blower 8 is operated at a normal rotational speed (high speed) each time it is pressed. Then, the operation is switched to the silent operation in which the rotation speed is lowered by a predetermined value and the LEDs 23b and 23c provided corresponding to the respective operations are turned on. The start / pause button 23d is used to select operation start / end / pause. The operation time setting button 23e can set the operation time to three lengths of 1 hour, 2 hours, and 3 hours, and the LED 23g, 23h, and 23i corresponding to the operation time is turned on each time the button is pressed. Then, the operation switching button 23f has the above-described drying (including deodorizing) operation mode, and the air to be cleaned by circulating the indoor air by controlling the ozone concentration to be high without storing clothes in the drying chamber 3. The mode can be switched to the clean operation mode, and each time the button is pressed, the corresponding LED 23j, 23k is turned on.

  Further, in the drying chamber 3, a clothing detection sensor Sb (see FIG. 4) including, for example, a load sensor and a transmission sensor is arranged as clothing detection means for detecting the presence or absence of clothing in the drying chamber 3. The air purifying mode can be activated only when it is determined that there is no clothing in the drying chamber 3 by being connected to the microcomputer mounted on the partial power supply board 14. Further, in the drying chamber 3, an ozone sensor Sc (see FIG. 4) as ozone concentration detecting means for detecting the ozone concentration is arranged, and the detected ozone concentration is mounted on the control unit power supply board 14 described above. It is configured to input to the microcomputer. As the ozone sensor Sc, a hot-wire semiconductor sensor that detects the gas concentration based on the same principle as the air contamination sensor Sa is used by changing the setting from the air contamination detection described above and optimizing the ozone concentration detection. Can do.

  As shown in the system configuration diagram of FIG. 4, the blower 8, the heater 10, the air pump 11, and the ozone generator 13 described above are input from the operation panel 23 disposed in the upper part of the drying chamber 3 and the air contamination sensor Sa described above. In accordance with inputs from the clothing detection sensor Sb and the ozone sensor Sc, power is supplied from the control unit power supply board 14 and optimally controlled to operate.

  In the above configuration, the suit jacket 5 or the like is hung on the hanger 6 and suspended in the drying chamber 3 so as to be parallel to the door 2, and the door 2 is closed and dried with the operation switching button 23f of the operation panel 23. When the mode is selected and set and the operation is started by the start / pause button 23d, the blower 8, the heater 10, the air pump 11, and the ozone generator 13 are operated.

  Since the blower 8 is installed in the machine room 4, clean air that has passed through the intake filter 19 provided in the intake port 18 is always introduced into the machine room 4 along with the operation of the blower 8. For this reason, the control unit and the power source mounted on the control unit power supply board 14 in the machine room 4 are always cooled. Further, since the air pump 11 is also installed in the machine room 4, the ozone generating element in the ozone generator 13 is not soiled or deteriorated by dust or the like by the air from the air pump 11.

  The air sent by the blower 8 is heated to a predetermined temperature (about 70 ° C.) by a heater 10 provided in the duct 9, sent to the duct chamber 16, and the top plate of the duct chamber 16 (of the drying chamber 3). The blowout part 17 formed in the bottom plate) is blown out as hot air into the drying chamber 3.

  Further, the air sent by the air pump 11 is introduced into the ozone generator 13, and the ozone generated here is sent into the duct 9 (or the duct chamber 16) immediately after the heater 10, and is evenly distributed with warm air in the duct chamber 16. To be mixed. At this time, the capacity of the ozone generator 13 is adjusted so that the ozone concentration in the drying chamber 3 is, for example, 0.05 to 0.2 ppm.

  Clothing such as the jacket 5 of the suit suspended in the drying chamber 3 is dried and deodorized for a set time by warm air and ozone. Although ozone has a higher specific gravity than air, it is mixed with warm air having a light specific gravity and blown into the drying chamber 3 together with the warm air, so that the inside of the drying chamber 3 can be raised together with the warm air.

  The warm air that has passed through the drying chamber 3 passes through an ozone removal filter 22 that is attached to the exhaust port 21 at the top of the drying chamber 3. At this time, the ozone removal filter 22 decomposes or adsorbs excess ozone, lowers the ozone concentration to 0.1 ppm or less, renders it harmless, and then releases it from the exhaust port 21 to the outside of the machine.

  Ozone has a strong oxidizing power, and the ozone concentration is lowered during the above-described deodorizing and drying mode. However, in the air cleaning mode, the ozone concentration is increased on the assumption that there is no clothing in the drying chamber 3. However, since it is conceivable that the user accidentally leaves the clothes in the drying chamber 3 due to a mistake or the like, the air cleaning mode is set only when the clothes detection sensor Sb that detects the presence or absence of clothes determines that there is no clothes. It is configured to operate.

  FIG. 67 is a flowchart showing an example of control of the air cleaning mode in the present embodiment, which is executed by a microcomputer mounted on the control unit power supply board 14.

  That is, when the air cleaning mode is selected by the operation switching button 23f of the operation panel 23 and the operation is started, the control shown in the flowchart of FIG. 7 is started. First, the clothing detection sensor Sb is turned on, and this clothing detection sensor In Sb, the presence or absence of clothing in the drying chamber 3 is checked (step S1 → step S2). If clothing is detected, the clothing detection sensor Sb is turned OFF to notify the presence of clothing, and the process ends (Y in step S2, step S3, and step S4).

  On the other hand, if no clothes are detected in step S2, the blower 8, the air pump 11, the ozone generator 13, the ozone sensor Sc, and the air dirt sensor Sa are turned ON (N in step S2 → step S5).

  Next, it is checked whether or not the end button has been pressed, and if not, it is checked whether or not the air dirt concentration detected by the air dirt sensor Sa exceeds a prescribed concentration for air cleaning (in step S6). N → Step S7).

  If the air dirt concentration does not exceed the specified concentration, air cleaning is not performed. Therefore, it is checked whether or not the ozone power supply is turned off (N in step S7 → step S8). If not, the ozone power supply is turned off. (Step S9), the process returns to the step S6, and if it is OFF, the process returns to the step S6 as it is.

  On the other hand, if the air dirt concentration exceeds the specified concentration, it is checked whether or not the ozone concentration detected by the ozone sensor Sc is less than the upper limit concentration (here, 1.0 ppm described above) (Y in step S7 → step S10). ). If the ozone concentration is less than the upper limit concentration, it is next checked whether the ozone concentration is less than the lower limit concentration (here, 0.4 ppm described above) (Y in step S10 → step S11). If the ozone concentration is not less than the lower limit concentration, the ozone concentration is in the predetermined range (0.4 to 1.0 ppm) in the air cleaning mode described above, so the process returns to step S6 and the above is repeated.

  If it is determined in step S11 that the ozone concentration is less than the lower limit concentration, it is first checked whether or not the ozone applied voltage exceeds 12V, which is the limit of the effectiveness of increasing ozone concentration (Y in step S11 → step S12). ). If the ozone applied voltage does not exceed 12V, the ozone applied voltage is increased by 1V (N in step S12 → step S13), the ozone concentration is increased, and the process returns to step S6 to repeat the above.

  Further, if the ozone applied voltage exceeds 12V, it is not effective even if the ozone applied voltage is further increased. Therefore, it is next checked whether or not the blower current exceeds the lower limit current (Y → step S12). Step S14). If the blower current does not exceed the lower limit current, the blower current cannot be lowered to decrease the air volume and increase the ozone concentration. Therefore, the process returns to step S6 and the above is repeated.

  If the blower current exceeds the lower limit current, the ozone concentration is increased by lowering the blower current and decreasing the air volume (Y in step S14 → step S15), and the process returns to step S6 and the above is repeated.

  On the other hand, if the ozone concentration is equal to or higher than the upper limit in step S10, it is further checked whether or not the ozone concentration exceeds a dangerous concentration that is higher than the upper limit that can be safely used (N in step S10 → step S16). Here, if the ozone concentration exceeds the dangerous concentration, it is dangerous to continue the operation as it is, so the ozone generation is turned off (Y in step S16 → step S17), and the process returns to step S6 and the above is repeated.

  If it is determined in step S16 that the ozone concentration does not exceed the dangerous concentration, it is checked whether or not the ozone power supply is OFF, and the ozone concentration exceeds the dangerous concentration and is turned OFF as described above. If so, the ozone power supply is turned on (Y in step S18 → step S19). If the ozone power supply is not turned off, the process proceeds to step S20. First, the ozone applied voltage is less than 5 V, which is the limit of the ozone concentration reduction effectiveness. Check if it exists. If the ozone applied voltage is not less than 5V, the ozone applied voltage is lowered by 1V (N in step S20 → step S21), the ozone concentration is reduced, and the process returns to step S6 to repeat the above.

  Further, if the ozone applied voltage is less than 5V, it is not effective even if the ozone applied voltage is further lowered, so it is next checked whether the blower current is less than the upper limit current (Y in step S20 → step S22). . If the blower current is greater than or equal to the upper limit current, the ozone current cannot be lowered by increasing the blower current and increasing the air volume. Therefore, the ozone generation is turned off (N in step S22 → step S23), Return to S6 and repeat the above.

  If the blower current is less than the upper limit current, the ozone concentration is reduced by increasing the blower current and increasing the air volume (Y in step S22 → step S24), and the process returns to step S6 and the above is repeated.

  If the end button is pressed while repeating the above-described control, the process proceeds from step S6 to step S25, and the blower 8, the air pump 11, the ozone generator 13, the ozone sensor Sc, the air dirt sensor Sa, and the clothing detection sensor Sb. To end the operation.

  As described above, according to the suit deodorizing dryer of the present embodiment, the air cleaning function in which the ozone concentration is higher than that at the time of deodorizing and drying the clothing only when the presence or absence of clothing is detected by the clothing detection sensor Sb. Can be used to clean the air in the room in which the dryer is installed without increasing the concentration of ozone without deodorizing the clothes. The air purifying function is activated while it is left inside, and the clothes are not decolorized by ozone with a high concentration, so the multifunctional clothing that can be used practically and effectively as an air purifier A dryer is obtained.

  In addition, when the air in the room where the dryer is installed is not dirty by the air contamination sensor Sa, the air cleaning function does not operate, and when the air in the room becomes clean by the operation of the air cleaning function, the air cleaning function operates. Since it is eliminated, unnecessary driving can be suppressed, and there is an energy saving effect.

  Furthermore, based on the ozone concentration detected by the ozone sensor Sc, the ozone applied voltage of the ozone generator 13 and the air volume of the blower 8 are controlled to control the ozone concentration within a predetermined range higher than that when clothes are deodorized and dried. As a result, the ozone concentration in the drying chamber 3 is substantially increased by increasing the ozone applied voltage, and is relatively increased if the air volume is decreased. Therefore, the ozone concentration in the drying chamber 3 is practically and effectively used in consideration of energy saving operation. A multifunctional clothes dryer that can be obtained. Furthermore, the combined use of the ozone application voltage control and the air volume control makes it easier to control the ozone concentration within a predetermined range that is higher than when deodorizing and drying clothes.

  In order to operate in the air cleaning mode, the air cleaning mode may be selected and set on the operation panel 23 as described above. However, in this embodiment, since the clothing detection sensor Sb is provided, the mode is not selected and set. When the operation start button is pressed, the clothing deodorization drying mode and the air cleaning mode may be automatically selected depending on the presence or absence of clothing.

  In the above control example, the heater 10 is not driven in the air cleaning mode, so that warm air can be prevented from being blown into the room and wasteful power consumption can be suppressed. Driving 10 can provide a heating function when the temperature is low in winter or the like, and a multifunctional clothes dryer that can be used as a heater in addition to an air purifier. It is also convenient if the heater 10 can be selectively set to ON / OFF.

  Further, in the above control example, when the end button is pressed, the load such as the blower 8 is turned off to end the operation. However, when the operation time is set, the blower 8 is used when the operation time has elapsed. The load may be turned off to end the operation.
