  In this embodiment, an example of a washing / drying machine having both washing and drying functions will be described.

  FIG. 1 is a configuration diagram of the movable shelf type washing and drying machine of the present embodiment. The washing and drying machine of the present embodiment includes a housing 1, a loading / unloading port that is opened / closed by a door portion 3 a when loading / unloading laundry 2 d, an upper conveyance region 3 including the loading / unloading port, and a lower portion than the upper conveyance region 3 Is provided with a lower sealed region 4 which is a water reservoir / drying chamber. In addition, one or a plurality of movable shelves 2 that are movable in the vertical direction by a shelf driving mechanism (not shown) are provided from the upper conveyance region 3 to the lower sealed region. The movable shelf 2 is formed in a net shape for placing the laundry 2d and facilitating passage of water and wind.

  When the laundry 2d is taken in and out through the carry-in / out port, the movable shelf 2 is positioned in the upper transport area 3 and when the laundry 2d is washed (washed or rinsed) in the lower sealed area 4, the movable shelf 2 is moved. Position it below. Here, the movable shelf 2 of the present embodiment includes a water / wind extraction port 2a and a detergent extraction port 2b, and is connected to the water / wind injection control device 8 via the water / wind injection flexible pipe 16. ing. By supplying water from the water / wind extraction port 2a of the movable shelf 2 using such a water supply device, water can be stored in the lower sealed region 4. In addition, the vibrator 5 is provided at the bottom of the lower sealed region 4, and ultrasonic cleaning is performed by generating ultrasonic waves in water during the cleaning process.

  Furthermore, the washing and drying machine of the present embodiment includes an opening / closing device configured with a sealing lid 4a for sealing the lower sealing region 4 and a vacuum control device (vacuum pump) 6 for evacuating the lower sealing region 4. Is provided. Then, during the drying process, the movable shelf 2 is positioned below, and the lower sealed region 4 is brought into a vacuum state by the vacuum controller 6 while the lower sealed region 4 is sealed by the sealing lid 4a. Then, drying can be accelerated | stimulated by sending a wind in the lower sealing area | region 4 from the water / wind extraction port 2a of the movable shelf 2. FIG. In addition, since the wind sent from the water / wind extraction port 2a directly hits the laundry 2d on the shelf, the effect of extending wrinkles can be expected.

  Further, a finishing blower fan 15 is provided as a blower in the housing 1, and a wind outlet (not shown) for blowing out air from the finish blower fan 15 is provided in the upper transfer area 3. Yes. And when the above-mentioned drying in the lower sealed area 4 is completed, the movable shelf 2 is moved to the upper upper conveyance area 3 by the shelf driving mechanism, and the air is blown from the air outlet toward the clothes placed on the movable shelf 2. , Improve the dry finish of clothing.

  Next, the washing and drying operation in this embodiment will be described with reference to the flowchart of FIG.

  In the process 20, the laundry 2d is installed on the movable shelf 2 in a folded state or an unfolded state. The installation method includes a method of placing the laundry 2d on the upper surface of the movable shelf 2, and a method of fixing the laundry 2d with two adjacent movable shelves 2 interposed therebetween. The position of the movable shelf 2 when the laundry 2d is installed on the movable shelf 2 is located in the upper conveyance area 3 in the housing 1. Next, the inside of the upper conveyance space 3 is sealed by closing the door portion 3a and bringing it into contact with the hermetic seal portion 3b. In addition, an operation for washing and drying is set in the laundry control panel 12.

  In the process 21, the sealing lid 4 a of the lower sealing region 4 is automatically opened in accordance with the operation of the laundry control panel 12. The sealing lid 4 a in the open state is housed in the walls on both sides of the lower sealing region 4.

  In the process 22, the laundry 2 is weighed through the movable shelf 2, and the extraction amount of water / wind and detergent is automatically determined. Thereafter, the movable shelf 2 is moved downward by the drive mechanism and is positioned inside the lower sealed region 4. Further, the interval between adjacent movable shelves 2 is adjusted to be half the wavelength of the standing wave from the vibrator 5. For example, since 1 wavelength = sound speed / frequency, in the case of 40 kHz, 1 wavelength = 1500,000 (mm / second) / 40000 (Hz) = 37.5 mm, and the standing wave is 37.5 mm / 2 = about 19 mm. is there. That is, since there is a place where dirt is removed in the range of every 19 mm, the interval of the movable shelf 2 is set to 19 mm.

  In the process 23, the sealing lid 4 a housed in the walls on both side surfaces of the lower sealing area 4 is automatically closed to seal the lower sealing area 4. FIG. 4 shows the position of the movable shelf 2 during the washing / rinsing step and the dehydration drying step. The water / wind injection flexible pipe 16 and the detergent injection flexible pipe 17 connected to the movable shelf 2 are from the state in which the movable shelf 2 is in the upper conveyance region 3 to the state in which the movable shelf 2 is in the lower sealed region 4. It is formed so that it can expand and contract.

  In the process 24, water is injected from the water / wind extraction port 2a provided in the movable shelf 2. The movable shelf 2 is connected to the water / wind injecting flexible pipe 16 via a connecting portion 16a. The water / wind injection flexible pipe 16 is connected to the water / wind injection control device 8, and the water / wind injection control device 8 is connected to the external water outlet 8a. Water injection is controlled by the water / wind injection control device 8, and water is sent to the water / wind extraction port 2 a of the movable shelf 2. In addition, the water exiting from the water / wind extraction port 2a is formed in the form of foam containing normal water or air.

  In the process 25, detergent is injected from the detergent extraction port 2b provided in the movable shelf 2. The movable shelf 2 is connected to the detergent injection flexible pipe 17 via a connecting portion 17a. The detergent injection flexible pipe 17 is connected to the detergent injection control device 10, and the detergent injection control device 10 is connected to the detergent tank 9. Detergent injection is controlled by the detergent injection control device 10, and the detergent is sent to the detergent extraction port 2 b of the movable shelf 2. In addition, the detergent exiting from the detergent extraction port 2b is formed in the form of a foam containing normal liquid detergent or air.

  Thus, since water and detergent can be sprayed directly on the laundry d on the shelf from the water / wind extraction port 2a and the detergent extraction port 2b, the cleaning power is improved. When the structure is simplified, the movable shelf 2 is not provided with an extraction port, and water is sprayed from the water supply device provided in the upper transport region 3 toward the movable shelf 2 in the form of a shower, or to the lower sealed region 4. You may supply water directly.

  In the process 26, the vibrator 5 is vibrated and ultrasonic waves are irradiated into water to generate a standing wave corresponding to the frequency. Here, the cleaning power is improved by arranging the movable shelf 2 for each range of an integral multiple of wavelength / 2. There are roughly two types of elements that exhibit the physical power of performing ultrasonic cleaning. One is cleaning by cavitation, and the other is cleaning by accelerating water molecules by ultrasonic waves. There are innumerable gas molecules in water, and when a powerful ultrasonic wave of about 20 kHz to 100 kHz is placed in the liquid, positive and negative pressures are alternately applied to the gas molecules. Gas molecules compressed under positive pressure expand violently with negative pressure at the next moment. By repeating this, the gas molecules have a very high pressure, and at that limit, they burst out and disappear. A shock wave (cavitation) when the foam is repelled acts on the laundry, resulting in a cavitation effect for peeling off the soiled material. In the ultrasonic cleaning for accelerating the water molecules, the water molecules are accelerated and collide with the laundry 2d, and the shock is caused to peel the soiled substance from the laundry 2d. In this case, a higher frequency is more effective. Instead of ultrasonic cleaning, cleaning that swings the movable shelf 2 in water may be performed.

  In the process 27, water is drained from the external drainage port 7a by using the drainage device 7, and water is injected from a plurality of water / wind extraction ports 2a provided in the movable shelf 2, and then rinsed by repeating water injection and drainage. Perform the process. After draining the water, the laundry 2d is sandwiched between the adjacent movable shelves 2 so that the moisture contained in the laundry 2d can be dehydrated.

  In the process 28, the vacuum controller 6 evacuates and depressurizes the inside of the lower sealed region 4 through the connecting portion 6a, thereby raising the boiling point of water and drying the laundry 2d at a low temperature. For example, when the pressure is reduced to 5 kPa, the moisture contained in the laundry 2d at a temperature of 50 ° C. is dried by exceeding the boiling point by the heater function of the movable shelf 2. The evaporated and gasified moisture is exhausted to the connecting portion 6a side of the vacuum control device 6. That is, since gas is a high pressure factor, it is sucked by a low pressure factor pump. In the present embodiment, the water reservoir portion that stores water during the washing process and the drying chamber that is evacuated during the drying process are common areas, but they may be different areas.

  In the process 29, the wind is sent from the water / wind injection control device 8 through the water / wind injection flexible pipe 16 and the connecting portion 16 a through the water / wind extraction port 2 a of the movable shelf 2. Here, the water / wind injection control device 8 is connected to the external air inlet 11 and the external water tap. Note that the water / wind injection control device 8 can also control the amount of air and water exiting from the water / wind extraction port 2a of each movable shelf 2 to be different.

  In the process 30, as in the process 21, the sealing lid 4a of the lower sealing region 4 is opened. In this open state, the sealing lid 4 a is accommodated in the walls on both sides of the lower sealing region 4.

  In the process 31, one or a plurality of movable shelves 2 in which the dried laundry 2 d is installed are automatically moved upward and positioned in the upper conveyance area 3. At this time, the intervals between the plurality of movable shelves 2 are substantially the same.

  In the process 32, the finishing blower fan device 15 sucks air from the intake / exhaust port 14 on the front side of the housing 1 and blows air on the laundry 2d that has been dried, thereby removing the fibers of the laundry 2d. Inflate and finish.

  In process 33, the user takes out the finished laundry 2d. At this time, the laundry 2d is maintained in a folded state or an unfolded state.

  Next, the configuration of the movable shelf 2 in the present embodiment will be specifically described with reference to FIGS. 5, 6, and 7. The movable shelf 2 shown in FIG. 5 includes a main body portion that includes a connecting portion 16a with the water / wind injecting flexible pipe 16 and is fixed to the shelf driving mechanism, and is detachable from the main body portion. 2a and a net-like mounting portion 2c having a detergent extraction port 2b. In addition, the mounting part 2c is connected with the detergent injection | pouring flexible pipe 17 via the connection part 17a. Further, the water / wind extraction port 2a and the detergent extraction port 2b may be provided toward the main body.

  For this reason, as shown in FIG. 6, the movable shelf 2 of the present embodiment can take out only the placement portion 2c from the carry-in / out port to the outside of the housing 1 with the laundry 2d placed thereon. Here, if the laundry 2d in a folded state is loaded on the placing portion 2c and is carried into the washing / drying machine and attached to the main body to start operation, the laundry 2d is folded even after the drying process is finished. State is maintained. Therefore, after drying, the placing portion 2c taken out from the main body in the washing / drying machine can be stored as it is in a separate closet. In addition to placing the laundry 2d on the placement portion 2c, the laundry 2d may be sandwiched and fixed by a plurality of placement portions 2c.

  Next, the function and effect of this embodiment will be described. In the present embodiment, since washing (clothing) can be taken in and out from above the washing (drying) machine during the washing (drying) operation, there is an advantage that the user can easily operate. In addition, since the tub is not rotated during the washing (drying) operation, the mechanical force applied to the laundry (clothing) is small and not only the fabric pain is suppressed. (Dry) finish is also improved.

  Furthermore, according to the present embodiment, the water is stored only in the water reservoir / drying chamber 4 below in the housing 1, and the water is not stored in the upper portion of the housing 1. Can do. Similarly, since only the water reservoir / drying chamber 4 needs to be evacuated, the efficiency is higher than when the entire housing 1 is evacuated, and the operation time and power consumption for drying are suppressed. Can do. In the present embodiment, if the laundry 2d is placed on the movable shelf 2 and dried in the folded or unfolded state, the state can be maintained even after drying, and the work load after drying can be reduced. .

  In the present embodiment, the vacuum control device 6 is used. However, water may be removed from the air by using a water-cooled dehumidifying mechanism, a heat pump unit, or the like and circulated again to the lower sealed region 4. Furthermore, when a predetermined course such as a power saving course is selected, air is not blown out from the water / wind extraction port 2a, and drying may be performed only by blowing from the finishing fan unit 15. Absent.
