The specific operation will be described in detail in the operation description to be described later.

  Next, the operation of the washing / drying machine W will be described with the above configuration. The washing / drying machine W of the present embodiment is provided with a plurality of operation selection switches for selecting an operation mode as an operation switch provided on the above-described operation panel (not shown). The operation selection switch has, for example, a first operation mode in which a washing operation using a conventional water and detergent, a rinsing step, a washing operation for performing a dehydration step, and a subsequent drying operation using the heat pump unit 20 are sequentially executed. In addition to the switch to be selected and the conventional washing operation and drying operation, a second operation mode is performed in which air containing ozone is supplied to the storage chamber 10 and an ozone cleaning process is performed to disinfect and deodorize the laundry by ozone. And a switch for selecting a plurality of operations such as a switch for selecting a third operation mode for executing only the ozone cleaning process. In the present embodiment, the operation in the case where the above three operation modes are selected will be described. However, the operation mode is an example and is not limited to the one described here. In the present embodiment, the second operation mode will be described on the assumption that an ozone cleaning process for performing ozone cleaning for sterilizing and deodorizing the laundry in the storage room is performed before the cleaning process in the washing operation.

(1) First operation mode First, a washing operation using a conventional water and detergent, a rinsing step, a washing operation for performing a dehydration step, and a subsequent drying operation using the heat pump unit 20 are sequentially executed. The operation mode will be described. A predetermined amount of detergent corresponding to the amount of laundry and the amount of the laundry to be washed is put into the storage chamber 10 in the inner tub drum 5 from the outlet 6, the open / close lid 3 is closed, and the operation switches described above When the power switch, the operation selection switch for washing the first operation mode, and the start switch are operated, the controller C executes the first operation mode. First, the washing operation is started by the controller C. Thereby, the water supply valve of the water supply passage is opened and the water supply passage is opened. Thereby, water is supplied from the water supply source through the through holes 7 of the outer tank drum 2 and the inner tank drum 5. The water supplied to the outer tank drum 2 also flows into the storage chamber 10 through the plurality of through holes 7 formed in the inner tank drum 5. At this time, the drain valve of the drain passage is closed.

  When a predetermined amount of water accumulates in the storage chamber 10 in the inner tank drum 5, the controller C closes the water supply valve and closes the water supply passage. Thereby, the supply of water from the water supply source is stopped.

  Next, the drive motor M is energized and activated by the controller C. As a result, the shaft 8 rotates, and the inner tub drum 5 attached to the shaft 8 starts to rotate in the outer tub drum 2, and the washing process of the washing operation is started. When a predetermined time has elapsed from the start of the washing process, the controller C stops the drive motor M, the drainage valve of the drainage passage is opened, and the inside of the storage chamber 10 of the inner tub drum 5 (that is, the outer tub drum 2). Water (washing water) will be discharged.

  When the water in the storage chamber 10 (in the outer tub drum 2) is discharged, the drive motor M is actuated again by the controller C, and the laundry is dehydrated. When this dehydration is executed for a predetermined time, the drain valve is closed and the drain passage is closed, and the process proceeds to the rinsing process.

  In this rinsing step, first, the water supply valve of the water supply passage is opened, and the water supply passage is opened. Thereby, water is again supplied from the water supply source into the outer tank drum 2 and the storage chamber 10. When a predetermined amount of water is supplied to the storage chamber 10 in the inner tank drum 5, the controller C closes the water supply valve and closes the water supply passage. Thereby, the supply of water from the water supply source is stopped.

  Then, after the rotation operation of the drive motor M is repeated for a predetermined time and the rinsing is performed, the drive motor M is stopped, the drain valve of the drain passage is opened, and the storage chamber 10 (inside the outer drum 2) is opened. Rinsing water is discharged into the drainage passage. When the rinsing water in the storage chamber 10 (in the outer tub drum 2) is discharged, the drive motor M is operated by the controller C, and the inner tub drum 5 is rotated in the same manner as described above to dehydrate the laundry. Migrate to

  When this dehydration step is executed for a predetermined time, the controller C closes the drain valve of the drain passage and closes the drain passage. Furthermore, the compressor 21 is started by the controller C and the operation of the fan 55 is started, and the inner drum 5 is rotated by the drive motor M to shift to the drying operation. At this time, the controller C switches the dampers 80 and 81 so that air flows through the air circulation path 50 provided with the heat radiator 22 and the heat absorber 24 of the heat pump unit 20 (FIG. 3). In FIG. 3, the arrows indicate the flow of circulating air in the drying operation.

On the other hand, when the compressor 21 is activated, the refrigerant (CO ₂ ) is sucked into the first rotary compression element of the compressor 21 from the refrigerant introduction pipe 25 and compressed. The refrigerant compressed to the intermediate pressure by the first rotary compression element is sucked into the second rotary compression element and is compressed in the second stage to become a high-temperature and high-pressure refrigerant gas. Discharged.

  The refrigerant gas discharged from the refrigerant discharge pipe 26 flows into the radiator 22 provided in the air circulation path 50. At this time, the temperature of the refrigerant flowing into the radiator 22 has risen to about + 100 ° C. to + 120 ° C., and the high-temperature and high-pressure refrigerant gas here radiates heat by exchanging heat with the air circulating in the air circulation path 50. , And cooled to about + 30 ° C. to + 50 ° C.

  The refrigerant cooled by the radiator 22 is then depressurized by the capillary tube 23, and then circulated air (air including moisture from the storage chamber 10) by the heat absorber 24 provided in the air circulation path 50. Evaporates through heat exchange. That is, the refrigerant circuit 20 condenses air containing moisture from the storage chamber 10 by the heat absorber 24 to remove moisture in the air, and pumps heat from the circulating air by the refrigerant in the heat absorber 24. It functions as a heat pump that heats the circulating air that is transported to the radiator 22 and discharged into the storage chamber 10.

  In this way, the refrigerant circuit 20 is provided, and moisture in the air from the storage chamber 10 is condensed and removed by the heat absorber 24. At this time, the heat pumped up from the air is conveyed to the radiator 22 by the refrigerant, and the storage chamber By using it for heating the circulating air discharged to 10, energy efficiency can be improved. In particular, since the circulating air can be heated to a high temperature without using a special heating means such as an electric heater by the radiator 22, energy costs such as electric energy are reduced, and a more efficient drying operation is realized. be able to.

  The refrigerant evaporated in the heat absorber 24 is then circulated through the refrigerant introduction pipe 25 and sucked into the compressor 21 again.

  In addition, by the operation of the fan 55, air containing air (circulation air) by drying the laundry in the storage chamber 10 was provided on the outer periphery of the outlet 6 of the one end surface 5A through the storage chamber 10. The air enters the air circulation path 50 from the suction port 52 formed below the support member 9 and passes through the heat absorber 24.

  At this time, the air containing moisture by drying the laundry in the storage chamber 10 exchanges heat with the refrigerant flowing through the heat absorber 24 and is deprived of heat by the refrigerant. The moisture in the air condenses on the surface of the heat absorber 24. As a result, the laundry can be dried by the heat absorber 24 to condense and remove moisture from the moisture-containing air, and the dried air can be obtained again.

  The water condensed on the surface of the heat absorber 24 is then dropped as a water droplet onto a drain pan (not shown) provided at the lower portion of the heat absorber 24 and discharged to the outside through a drain pipe, a drainage passage, and the like. The

  On the other hand, the air that has been dried by removing moisture from the heat absorber 24 is deprived of heat by the refrigerant flowing through the heat absorber 24 and is cooled to about + 20 ° C. to + 40 ° C. Then, after passing through the periphery of the radiator 22 and exchanging heat with the high-temperature and high-pressure refrigerant gas flowing through the radiator 22 and being heated to + 90 ° C. to + 110 ° C., the air is sucked into the fan 55 and other than the outer drum 2 The air is discharged into the housing chamber 10 through the blowout port 54 formed above the end surface 2B and the through hole 7 formed in the other end surface 5B of the inner tank drum 5.

  And the air which dried the to-be-washed object in the storage chamber 10 and contained moisture repeats the cycle sucked in the air circulation path 50 from the said suction inlet 52 formed in 5 A of one end surfaces of the inner tank drum 5. FIG. By performing such a drying operation, the laundry in the storage room 10 is completely dried. Then, when the drying operation is performed and the temperature of the air passing through the storage chamber 10 rises to a predetermined temperature, or when the drying operation is performed for a predetermined time, the controller C ends the drying operation.

(2) Second operation mode Next, in the washing operation, before the washing step, an ozone cleaning step for performing ozone cleaning for sterilizing and deodorizing the laundry in the storage chamber is performed, and then the first operation mode is performed. A second operation mode in which the washing operation using the same water and detergent, the rinsing step, and the dehydration step, and the subsequent drying operation using the heat pump unit 20 are sequentially executed will be described. A predetermined amount of detergent corresponding to the amount of laundry and the amount of the laundry to be washed is put into the storage chamber 10 in the inner tub drum 5 from the outlet 6, the open / close lid 3 is closed, and the operation switches described above When the power switch, the selection switch for washing the second operation mode, and the start switch are operated, the controller C executes the second operation mode. First, the dampers 80 and 81 are switched by the controller C as shown in FIG. That is, the controller C switches the dampers 80 and 81 so that air flows through the bypass path 100, operates the drive motor M, and rotates the inner tank drum 5. In FIG. 2, the arrows indicate the air flow in this case.

  The controller C opens the valve 77V simultaneously with the operation of the dampers 80 and 81, and starts the operation of the ozone generator 70 and the fan 55. Thereby, the air outside the washing / drying machine W is taken into the main body B of the washing / drying machine W from the air path 72 and passes through the ozone generator 70 through the filter 75. At this time, corona discharge is applied to the air to generate ozone. The generated ozone-containing air enters the air circulation path 50 via the supply path 77, is sucked into the fan 55, and is formed above the other end face 2B of the outer tank drum 2. The drum 5 is discharged into the accommodation chamber 10 through the through holes 7 formed in the other end surface 5B. In the present embodiment, the connection position of the supply path 77 to the air circulation path 50 is provided on the suction side of the fan 55. For this reason, since the suction side becomes negative pressure by the operation of the fan 55, the ozone generator 70 can be configured with a simple configuration without providing a special device such as an air pump for supplying air containing ozone to the air circulation path 50. The air containing the ozone generated in step S <b> 1 can be supplied into the air circulation path 50, and can be discharged from there into the storage chamber 10 by the fan 55.

  Thereby, the air containing ozone can be supplied to the laundry in the storage chamber 10. Odorous components, germ components, and the like attached to the laundry in the storage room 10 are oxidized by the supplied ozone, and thus the laundry can be deodorized and sterilized. Thereafter, the air in the storage chamber 10 is sucked into the air circulation path 50 from the suction port 52 formed on the one end surface 5A of the inner tank drum 5, and again sucked into the fan 55 through the bypass path 100. The cycle discharged in 10 is repeated. At this time, the above-described dampers 80 and 81 having excellent airtightness reliably prevent circulating air containing ozone from flowing into the air circulation path 50 in which the heat radiator 22 and the heat absorber 24 of the heat pump unit 20 are provided. be able to.

  In order to improve the deodorizing and sterilizing effect of the laundry, it is preferable to supply ozone to the laundry to be dried as in this embodiment. Therefore, the ozone cleaning process is desirably performed before the cleaning process in which the laundry is dried as in the present embodiment or after the drying operation is completed. Further, by performing the ozone cleaning step before the cleaning step as in this embodiment, the dirt component adhering to the laundry is decomposed into ozone, so that the cleaning effect can be improved. In the present embodiment, the ozone supply to the storage chamber 10 is performed before the cleaning process. However, the present invention is not limited to this, and may be performed after the drying operation.

  On the other hand, the controller C stops the operation of the fan 55 and the energization of the drive motor M, closes the valve 77V, and stops the ozone generator 70 when a predetermined time has elapsed since the start of the ozone cleaning process. Then, the process proceeds to a cleaning process using water and a detergent. In the washing operation after the washing step, the dampers 80 and 81 are maintained in a state where they are switched so that air flows through the bypass path 100. This is because if the ozone supplied to the storage chamber 10 remains without being decomposed, the ozone may flow into the heat pump unit 20, so that the dampers 80, 81 ensure that the heat pump unit 20 flows into the heat pump unit 20. By blocking, the inflow of ozone to the heat pump unit 20 can be reliably blocked.

  And if it transfers to the said washing | cleaning process, the water supply valve of the said water supply channel will be opened by the controller C, and a water supply channel will be open | released. Thereby, water is supplied from the water supply source through the through holes 7 of the outer tank drum 2 and the inner tank drum 5. The water supplied to the outer tank drum 2 also flows into the storage chamber 10 through the plurality of through holes 7 formed in the inner tank drum 5. At this time, the drain valve of the drain passage is closed.

  When a predetermined amount of water accumulates in the storage chamber 10 in the inner tank drum 5, the controller C closes the water supply valve and closes the water supply passage. Thereby, the supply of water from the water supply source is stopped.

  Next, the drive motor M is energized and activated by the controller C. As a result, the shaft 8 rotates, and the inner tub drum 5 attached to the shaft 8 starts to rotate in the outer tub drum 2, and the washing process of the washing operation is started. When a predetermined time has elapsed from the start of the washing process, the controller C stops the drive motor M, the drainage valve of the drainage passage is opened, and the inside of the storage chamber 10 of the inner tub drum 5 (that is, the outer tub drum 2). Water (washing water) will be discharged.

When the water in the storage chamber 10 (in the outer tub drum 2) is discharged, the drive motor M is actuated again by the controller C, and the laundry is dehydrated. When this dehydration is executed for a predetermined time, the drain valve is closed and the drain passage is closed, and the process proceeds to the rinsing process.
In this rinsing step, first, the water supply valve of the water supply passage is opened, and the water supply passage is opened. Thereby, water is again supplied from the water supply source into the outer tank drum 2 and the storage chamber 10. When a predetermined amount of water is supplied to the storage chamber 10 in the inner tank drum 5, the controller C closes the water supply valve and closes the water supply passage. Thereby, the supply of water from the water supply source is stopped.

  Then, after the rotation operation of the drive motor M is repeated for a predetermined time and the rinsing is performed, the drive motor M is stopped, the drain valve of the drain passage is opened, and the storage chamber 10 (inside the outer drum 2) is opened. Rinsing water is discharged into the drainage passage. When the rinsing water in the storage chamber 10 (in the outer tub drum 2) is discharged, the drive motor M is operated by the controller C, and the inner tub drum 5 is rotated in the same manner as described above to dehydrate the laundry. Migrate to

  When this dehydration step is executed for a predetermined time, the controller C closes the drain valve of the drain passage and closes the drain passage. Furthermore, the compressor 21 is started by the controller C and the operation of the fan 55 is started, and the inner drum 5 is rotated by the drive motor M to shift to the drying operation. At this time, the controller C switches the dampers 80 and 81 so that air flows through the air circulation path 50 provided with the heat radiator 22 and the heat absorber 24 of the heat pump unit 20 (FIG. 3). Thus, there is a sufficient time from the end of the ozone cleaning process to the start of the drying operation, and ozone is also reliably decomposed during that time. Therefore, it is possible to reliably prevent the inconvenience of ozone flowing into the heat pump unit 20 by shifting to the drying operation and switching the dampers 80 and 81.

On the other hand, when the compressor 21 is activated, the refrigerant (CO ₂ ) is sucked into the first rotary compression element of the compressor 21 from the refrigerant introduction pipe 25 and compressed. The refrigerant compressed to the intermediate pressure by the first rotary compression element is sucked into the second rotary compression element and is compressed in the second stage to become a high-temperature and high-pressure refrigerant gas. Discharged.

  The refrigerant gas discharged from the refrigerant discharge pipe 26 flows into the radiator 22 provided in the air circulation path 50. At this time, the temperature of the refrigerant flowing into the radiator 22 has risen to about + 100 ° C. to + 120 ° C., and the high-temperature and high-pressure refrigerant gas here radiates heat by exchanging heat with the air circulating in the air circulation path 50. , And cooled to about + 30 ° C. to + 50 ° C.

  The refrigerant cooled by the radiator 22 is then depressurized by the capillary tube 23, and then circulated air (air including moisture from the storage chamber 10) by the heat absorber 24 provided in the air circulation path 50. Evaporates through heat exchange. That is, the refrigerant circuit 20 condenses air containing moisture from the storage chamber 10 by the heat absorber 24 to remove moisture in the air, and pumps heat from the circulating air by the refrigerant in the heat absorber 24. It functions as a heat pump that heats the circulating air that is transported to the radiator 22 and discharged into the storage chamber 10.

  In this way, the refrigerant circuit 20 is provided, and moisture in the air from the storage chamber 10 is condensed and removed by the heat absorber 24. At this time, the heat pumped up from the air is conveyed to the radiator 22 by the refrigerant, and the storage chamber By using it for heating the circulating air discharged to 10, energy efficiency can be improved. In particular, since the circulating air can be heated to a high temperature without using a special heating means such as an electric heater by the radiator 22, energy costs such as electric energy are reduced, and a more efficient drying operation is realized. be able to.

  The refrigerant evaporated in the heat absorber 24 is then circulated through the refrigerant introduction pipe 25 and sucked into the compressor 21 again.

  In addition, by the operation of the fan 55, air containing air (circulation air) by drying the laundry in the storage chamber 10 was provided on the outer periphery of the outlet 6 of the one end surface 5A through the storage chamber 10. The air enters the air circulation path 50 from the suction port 52 formed below the support member 9 and passes through the heat absorber 24.

  At this time, the air containing moisture by drying the laundry in the storage chamber 10 exchanges heat with the refrigerant flowing through the heat absorber 24 and is deprived of heat by the refrigerant. The moisture in the air condenses on the surface of the heat absorber 24. As a result, the laundry can be dried by the heat absorber 24 to condense and remove moisture from the moisture-containing air, and the dried air can be obtained again.

  The water condensed on the surface of the heat absorber 24 is then dropped as a water droplet onto a drain pan (not shown) provided at the lower portion of the heat absorber 24 and discharged to the outside through a drain pipe, a drainage passage, and the like. The

  On the other hand, the air that has been dried by removing moisture from the heat absorber 24 is deprived of heat by the refrigerant flowing through the heat absorber 24 and is cooled to about + 20 ° C. to + 40 ° C. Then, after passing through the periphery of the radiator 22 and exchanging heat with the high-temperature and high-pressure refrigerant gas flowing through the radiator 22 and being heated to + 90 ° C. to + 110 ° C., the air is sucked into the fan 55 and other than the outer drum 2 The air is discharged into the housing chamber 10 through the blowout port 54 formed above the end surface 2B and the through hole 7 formed in the other end surface 5B of the inner tank drum 5.

  And the air which dried the to-be-washed object in the storage chamber 10 and contained moisture repeats the cycle sucked in the air circulation path 50 from the said suction inlet 52 formed in 5 A of one end surfaces of the inner tank drum 5. FIG. By performing such a drying operation, the laundry in the storage room 10 is completely dried. Then, when the drying operation is performed and the temperature of the air passing through the storage chamber 10 rises to a predetermined temperature, or when the drying operation is performed for a predetermined time, the controller C ends the drying operation.

(3) 3rd operation mode Next, the 3rd operation mode which performs only an ozone cleaning process is explained. The laundry is put into the storage chamber 10 in the inner tub drum 5 from the outlet 6, the open / close lid 3 is closed, and the power switch among the operation switches described above, the operation selection for washing the third operation mode. When the switch and the start switch are operated, the controller C executes the third operation mode. First, the dampers 80 and 81 are switched by the controller C as shown in FIG. That is, the controller C switches the dampers 80 and 81 so that air flows through the bypass path 100. In the third operation mode of the present embodiment, the drive motor M is not started.

  The controller C opens the valve 77V simultaneously with the operation of the dampers 80 and 81, and starts the operation of the ozone generator 70 and the fan 55. Thereby, the air outside the washing / drying machine W is taken into the main body B of the washing / drying machine W from the air path 72 and passes through the ozone generator 70 through the filter 75. At this time, corona discharge is applied to the air to generate ozone. The generated ozone-containing air enters the air circulation path 50 via the supply path 77, is sucked into the fan 55, and is formed above the other end face 2B of the outer tank drum 2. The drum 5 is discharged into the accommodation chamber 10 through the through holes 7 formed in the other end surface 5B. In the present embodiment, the connection position of the supply path 77 to the air circulation path 50 is provided on the suction side of the fan 55. For this reason, since the suction side becomes negative pressure by the operation of the fan 55, the ozone generator 70 can be configured with a simple configuration without providing a special device such as an air pump for supplying air containing ozone to the air circulation path 50. The air containing the ozone generated in step S <b> 1 can be supplied into the air circulation path 50, and can be discharged from there into the storage chamber 10 by the fan 55.

  Thereby, the air containing ozone can be supplied to the laundry in the storage chamber 10. Odorous components, germ components, and the like attached to the laundry in the storage room 10 are oxidized by the supplied ozone, and thus the laundry can be deodorized and sterilized. Thereafter, the air in the storage chamber 10 is sucked into the air circulation path 50 from the suction port 52 formed on the one end surface 5A of the inner tank drum 5, and again sucked into the fan 55 through the bypass path 100. The cycle discharged in 10 is repeated.

  On the other hand, the controller C stops the operation of the fan 55, closes the valve 77V, stops the ozone generator 70, and stops the ozone cleaning process when a predetermined time has elapsed since the start of the ozone cleaning process. Exit. Thus, in the third operation mode, only the washing operation of the laundry using ozone without using water or detergent (mainly the operation for deodorizing and sterilizing the laundry) is performed. For this reason, it is possible to deodorize and sterilize items that have conventionally been difficult to wash with water or detergent (for example, leather products and silk clothing) by selecting the third operation mode. In the present embodiment, the drive motor M is not operated as described above in the third operation mode, and the inner tank drum 5 is not rotated. Can be washed (deodorized / sanitized).

  As described above in detail, when the ozone generator 70 is operated, it is generated in the ozone generator 70 by switching the flow path so that air flows through the bypass path 100 with the dampers 80 and 81 as the flow path control device. The ozone-containing air can be circulated in the storage chamber 10 by bypassing the heat pump unit 20. Accordingly, the heat pump unit 20 can be protected from ozone while ozone is circulated using a part of the air circulation path 50 for drying.

  Thereby, ozone generated in the ozone generator 70 flows into heat exchangers such as the heat radiator 22 and the heat absorber 24 of the heat pump unit 20, and it is possible to reliably prevent inconvenience of deteriorating them. Further, since ozone can be circulated by using a part of the air circulation path 50 for drying, a special path for circulating ozone is not provided, and the air circulation path 50 is not complicated. A heat pump type washing and drying machine W having an ozone cleaning function while preventing deterioration of the heat pump unit with a simple structure can be realized.

  Next, a washing / drying machine according to another embodiment to which the present invention is applied will be described with reference to FIG. FIG. 4 is a schematic view seen from the side of the washing / drying machine W to which the present invention is applied. 4, components having the same reference numerals as those in FIGS. 1 to 3 have the same or similar functions or effects and will not be described. In addition, since the washing / drying machine W of a present Example is as substantially the same structure as the washing / drying machine W of Example 1, description is abbreviate | omitted about the same structure and only a different point from the washing / drying machine W is demonstrated.

  In the bypass path 100 of the present embodiment shown in FIG. 4, a heater 120 is installed as an ozone decomposing means for decomposing ozone contained in the air entering the storage chamber 10 via the bypass path 100. The heater 120 is for decomposing ozone contained in the air by heating the air entering the storage chamber 10 via the bypass path 100, and the operation is controlled by the controller C. In the present embodiment, the heater 120 is energized by the controller C immediately after the end of the ozone cleaning process and at the beginning of the drying operation.

  That is, in this embodiment, the fan 55 is not stopped simultaneously with the end of the ozone cleaning process as in the above embodiment, and the fan 55 is operated for a predetermined short time after the end, and during that time (the ozone cleaning process is completed). The heater 120 is controlled to be energized for a short time while the fan 55 is in operation. Thereby, since the circulating air which flows through the bypass path | route 100 can be heated with the heater 120, the ozone supplied in the ozone washing | cleaning process can be decomposed | disassembled early by the heat | fever of the heater 120. FIG.

  The operation in this case will be described using the second operation mode. First, a predetermined amount of detergent corresponding to the amount of laundry and the amount of laundry to be washed is put into the storage chamber 10 in the inner tub drum 5 from the outlet 6, the open / close lid 3 is closed, and the operation switch described above is operated. When the power switch, the selection switch for washing the second operation mode, and the start switch are operated, the controller C executes the second operation mode. First, the controller C switches the dampers 80 and 81 so that air flows through the bypass path 100, operates the drive motor M, and rotates the inner tank drum 5.

  The controller C opens the valve 77V simultaneously with the operation of the dampers 80 and 81, and starts the operation of the ozone generator 70 and the fan 55. Thereby, the air outside the washing / drying machine W is taken into the main body B of the washing / drying machine W from the air path 72 and passes through the ozone generator 70 through the filter 75. At this time, corona discharge is applied to the air to generate ozone. The generated ozone-containing air enters the air circulation path 50 via the supply path 77, is sucked into the fan 55, and is formed above the other end face 2B of the outer tank drum 2. The drum 5 is discharged into the accommodation chamber 10 through the through holes 7 formed in the other end surface 5B.

  Odorous components, germ components, and the like attached to the laundry in the storage room 10 are oxidized by the supplied ozone, and thus the laundry can be deodorized and sterilized. Thereafter, the air in the storage chamber 10 is sucked into the air circulation path 50 from the suction port 52 formed on the one end surface 5A of the inner tank drum 5, and again sucked into the fan 55 through the bypass path 100. The cycle discharged in 10 is repeated.

  On the other hand, when a predetermined time has elapsed since the start of the ozone cleaning step, the controller C stops energization of the drive motor M, closes the valve 77V, and stops the ozone generator 70. Next, the controller C starts energizing the heater 120. At this time, the dampers 80 and 81 are kept switched so that air flows through the bypass path 100, and the fan 55 is also operated continuously.

  When the fan 55 is continuously operated, air is sucked into the air circulation path 50 from the suction port 52, sucked into the fan 55 through the bypass path 100, and discharged into the housing chamber 10 from the blowout port 54. Repeat the cycle. At this time, the circulating air passing through the bypass path 100 is heated by energizing the heater 120 provided in the bypass path 100. In the process of passing through the bypass path 100, ozone in the air supplied in the ozone cleaning process and remaining without being decomposed can be effectively decomposed by the heat of the heater 120. Thereby, ozone can be decomposed early by the heater 120.

  Then, after the ozone cleaning process is completed, the controller C stops the operation of the fan 55 and the heater 120 when the operation of the fan 55 and the heater 120 are energized and a predetermined time elapses, and then proceeds to the next cleaning process. In the present embodiment, the circulating air flowing through the bypass path 100 is heated by the heater 120 to reliably decompose ozone, so that the dampers 80 and 81 are connected to the bypass path 100 in the washing operation after the cleaning step. It is good also as the state switched so that air may flow, and you may switch so that it may flow to the heat pump unit 20 side. In the present embodiment, as in the second operation mode of the first embodiment, in the washing operation after the washing process, the dampers 80 and 81 are maintained in a state of being switched so that air flows through the bypass path 100. Shall. Note that the washing operation after the washing step in this case is the same as the second operation mode described in the first embodiment, and thus the description thereof is omitted.

  When the dehydration process is executed for a predetermined time and the operation is shifted to the drying operation, the compressor 21 is started by the controller C, the operation of the fan 55 is started, and the rotation of the inner tank drum 5 by the drive motor M is started. . At this time, the controller C switches the dampers 80 and 81 so that air flows through the bypass path 100 simultaneously with the operation of the fan 55 and starts energization of the heater 120. Thereby, the air is sucked into the air circulation path 50 from the suction port 52, sucked into the fan 55 through the bypass path 100, and the circulation discharged from the blowout port 54 into the accommodation chamber 10 is repeated. At this time, the circulating air passing through the bypass path 100 is heated by energizing the heater 120 provided in the bypass path 100. Thereby, the high temperature air heated with the heater 120 can be discharged to the storage chamber 10. In particular, the drying-type washing dryer W using a heat pump as in this example had a slow start-up compared to the drying method using a heater. As a result, there has been a problem that the drying time is prolonged as compared with a heater-type washing dryer. Therefore, as in the present invention, by using the heater 120 as the ozonolysis means mounted for ozonolysis, the drying air is heated by the heater 120 at the initial stage of the drying operation, thereby promoting the increase of the circulating air temperature. It becomes possible. Thereby, the start-up of the drying operation can be improved, and the drying time can be shortened.

  On the other hand, when the controller C shifts to the drying operation and a predetermined time elapses, the dampers 80 and 81 are switched so that air flows through the air circulation path 50 in which the heat radiator 22 and the heat absorber 24 of the heat pump unit 20 are provided. In the present embodiment, the operation of the refrigerant flowing through the refrigerant circuit of the heat pump unit 20 is the same as that in the first embodiment, and thus the description thereof is omitted here.

  On the other hand, when the dampers 80 and 81 are switched (when switching is performed so that air flows into the air circulation path 50 provided with the heat radiator 22 and the heat absorber 24 of the heat pump unit 20), the laundry in the storage chamber 10 is moved. The dried air containing moisture (circulated air) passes through the storage chamber 10 from the suction port 52 formed below the support member 9 provided on the outer periphery of the outlet 6 on the one end surface 5A. And passes through the heat absorber 24.

  At this time, the air containing moisture by drying the laundry in the storage chamber 10 exchanges heat with the refrigerant flowing through the heat absorber 24 and is deprived of heat by the refrigerant. The moisture in the air condenses on the surface of the heat absorber 24. As a result, the laundry can be dried by the heat absorber 24 to condense and remove moisture from the moisture-containing air, and the dried air can be obtained again.

  The water condensed on the surface of the heat absorber 24 is then dropped as a water droplet onto a drain pan (not shown) provided at the lower portion of the heat absorber 24 and discharged to the outside through a drain pipe, a drainage passage, and the like. The

  On the other hand, the air that has been dried by removing moisture from the heat absorber 24 is deprived of heat by the refrigerant flowing through the heat absorber 24 and is cooled to about + 20 ° C. to + 40 ° C. Then, after passing through the periphery of the radiator 22 and exchanging heat with the high-temperature and high-pressure refrigerant gas flowing through the radiator 22 and being heated to + 90 ° C. to + 110 ° C., the air is sucked into the fan 55 and other than the outer drum 2 The air is discharged into the housing chamber 10 through the blowout port 54 formed above the end surface 2B and the through hole 7 formed in the other end surface 5B of the inner tank drum 5.

  And the air which dried the to-be-washed object in the storage chamber 10 and contained moisture repeats the cycle sucked in the air circulation path 50 from the said suction inlet 52 formed in 5 A of one end surfaces of the inner tank drum 5. FIG. By performing such a drying operation, the laundry in the storage room 10 is completely dried. Then, when the drying operation is performed and the temperature of the air passing through the storage chamber 10 rises to a predetermined temperature, or when the drying operation is performed for a predetermined time, the controller C ends the drying operation.

  In this embodiment, the heater 120 is installed in the bypass path 100 as described above, but the installation position of the heater 120 is not limited to the position of the above embodiment. For example, as shown in FIG. 5, the heater 120 may be provided at a position on the upstream side of the air inlet 100 </ b> A of the bypass path 100, or in the air circulation path 50 on the air downstream side of the outlet 100 </ b> B of the bypass path 100. The present invention is effective even if it is installed. In particular, when installing in the air circulation path 50 on the air downstream side from the outlet 100B of the bypass path 100, it may be installed in the air circulation path 50 on the discharge side of the fan 55 as shown in FIG. As shown in FIG. 7, on the suction side of the fan 55 and downstream of the connection position of the supply path 77, that is, in the air circulation path 50 on the fan 55 side of the connection position of the supply path 77, or in FIG. As described above, the present invention is effective even if installed in the air circulation path 50 on the air upstream side from the connection position of the supply path 77, that is, on the outlet 100B side of the bypass passage 100 from the connection position of the supply path 77.

  Further, in each of the above embodiments, the fan 55 as the air blowing means is connected to the supply passage 77 on the air downstream side of the radiator 22 in the air circulation path 50 and on the air downstream side from the outlet 100B of the bypass path 100. However, the position of the fan is not limited to the position of the embodiment, and as shown in FIG. 9, the inlet 100A of the bypass path 100 is installed in the air circulation path 50 in the vicinity of the air outlet 100B on the downstream side of the position. The present invention is effective even if it is installed in the air circulation path 50 in the vicinity of the suction port 52 on the air upstream side.

  In the washing / drying machine W of the present embodiment shown in FIG. 9, the ozone generator 70 is installed in the lower part of the front surface of the storage chamber 10 in the main body B, and the ozone generator 70 is provided on the outlet side (air downstream side) of the ozone generator 70. The supply path 77 is connected to the air circulation path 50 between the fan 55 on the suction side of the fan 55 and the suction port 52. Thus, by providing the connection position of the supply path 77 to the air circulation path 50 on the suction side of the fan 55, the suction side becomes negative pressure by the operation of the fan 55. Air containing ozone generated by the ozone generator 70 is supplied into the air circulation path 50 with a simple configuration without providing a special device such as an air pump for supplying the air to the housing 50, and from there to the housing chamber 10 by the fan 55. Can be discharged.

  Further, in the washing / drying machine W having the configuration shown in FIG. 9, the heater 120 as the ozone decomposing means is installed as in the second embodiment, and the air entering the accommodation chamber 10 through the bypass path 100 is heated by the heater 120. It is good as a thing. By providing the heater 120 and energizing the controller C immediately after the end of the ozone cleaning step, ozone can be decomposed quickly by the heat of the heater 120 after cleaning with ozone by the heat of the heater 120. Furthermore, by energizing at the initial stage of the drying operation and heating the drying air with a heater at the initial stage of the drying operation, it is possible to promote an increase in the circulating air temperature. As a result, the start of the drying operation can be improved, and the drying time can be shortened.

  The installation position of the heater 120 in this case may be in the bypass path 100 as shown in FIG. 10, or a position or bypass path on the air downstream side from the outlet 100 </ b> B of the bypass path 100 as shown in FIG. 11. 100 may be installed in the air circulation path 50 on the upstream side of the air inlet 100A. In particular, when the heater 120 is installed in the air circulation path 50 on the air upstream side from the inlet 100A of the bypass path 100, it is on the suction side of the fan 55 as shown in FIG. In the air circulation path 50 on the air upstream side from the position, that is, on the suction port 52 side from the connection position of the supply path 77, or on the air downstream side from the connection position of the supply path 77 as shown in FIG. The present invention is effective as being installed in the air circulation path 50 on the discharge side of the fan 55 as shown in FIG. .

It is also good. By providing the heater 120 and energizing the controller C immediately after the end of the ozone cleaning step, ozone can be decomposed quickly by the heat of the heater 120 after cleaning with ozone by the heat of the heater 120. Furthermore, by energizing at the initial stage of the drying operation and heating the drying air with a heater at the initial stage of the drying operation, it is possible to promote an increase in the circulating air temperature. As a result, the start of the drying operation can be improved, and the drying time can be shortened.

  In this case, the heater 120 may be installed in the bypass path 100 as shown in FIG. 22 or in the air circulation path 50 upstream of the inlet 100A of the bypass path 100 as shown in FIG. In addition, the heater 120 may be provided in the air circulation path 50 on the air downstream side of the outlet 100B of the bypass path 100. In particular, when the heater 120 is installed in the air circulation path 50 on the air downstream side of the outlet 100B of the bypass path 100, the heater 120 is installed in the air circulation path 50 on the discharge side of the fan 55 as shown in FIG. 25, the suction side of the fan 55 as shown in FIG. 25, the air downstream side from the connection position of the supply path 77, that is, the air circulation path 50 on the fan 55 side from the connection position of the supply path 77, Alternatively, as shown in FIG. 26, it is also effective to install in the air circulation path 50 on the air upstream side from the connection position of the supply path 77, that is, on the outlet 100B side of the bypass path 100 from the connection position of the supply path 77.
