  A washing method according to one aspect of the present invention is a washing method for washing a duvet, and stores water containing microbubbles as water for washing or rinsing the duvet (for example, step S11 in FIG. 8). The method includes a step of putting a medium containing useful microorganisms in water stored for washing or rinsing (for example, step S12 in FIG. 8).

  FIG. 1 is a block diagram showing a configuration of a laundry system according to an embodiment of the present invention. The washing system 1 is a system for washing a futon such as a duvet, a duvet, a wool duvet, a cotton duvet, or a synthetic duvet. ) It consists of the active liquid generator 14.

  The washing apparatus 11 uses the purified water supplied from the waste water purification apparatus 12, the EM active liquid generated by the EM active liquid generator 14, and the microbubble water generated by the microbubble water generation apparatus 13. To wash. The washing device 11 supplies the waste water used for washing to the waste water purification device 12.

  The waste water purification apparatus 12 purifies the waste water from the washing apparatus 11 using the EM active liquid generated by the EM active liquid generator 14. That is, the waste water purification apparatus 12 purifies the waste water from the washing apparatus 11 by EM cultured in the EM active liquid generator 14.

  Here, EM refers to a “useful microorganism group” in which “Effective” and “microorganisms” are combined. The useful microorganism group is mainly composed of lactic acid bacteria, yeast, and photosynthetic bacteria. In the useful microorganism group, safe and useful microorganisms coexist. In addition to lactic acid bacteria, yeast, and photosynthetic bacteria, useful microorganisms include fermentation filamentous fungi, gram-positive actinomycetes, and the like. In general, many causes of environmental deterioration such as bad odor and water pollution are caused by the propagation of rot (oxidation) type microorganisms. Odor and water pollution can be prevented by colonizing useful microorganisms before rotting.

  In other words, the waste water purification apparatus 12 purifies the waste water from the washing apparatus 11 using the useful microorganism group cultured in the EM active liquid generator 14.

  When the water tank described later is full, the waste water purification device 12 discharges the waste water from the washing device 11 as it is due to so-called overflow.

  The micro bubble water generating device 13 generates micro bubble water from the tap water supplied from the water supply, and supplies the generated micro bubble water to the washing device 11.

  Microbubble water is water containing microbubbles. Microbubbles are fine bubbles having a bubble diameter of several tens of μm or less when generated. Like air, the microbubble contains about 20% oxygen and about 80% nitrogen, as well as argon and carbon dioxide as trace components. Microbubbles have different physical and chemical properties than ordinary bubbles (macrobubbles).

  Ordinary bubbles (macro bubbles) are quickly lifted from the water due to the difference in specific gravity with water. As the water pressure decreases in the upper layer, the diameter of ordinary bubbles (macro bubbles) increases, and ordinary bubbles (macro bubbles) burst on the surface of water.

  In contrast, microbubbles stay in water for a relatively long time and disappear in water. In microbubbles with a small diameter, the surface area relative to the diameter is large. As a result, the dissolution rate of oxygen from the microbubbles increases, and the local concentration of oxygen increases in the vicinity of the microbubbles.

  Furthermore, the surface of the microbubble is charged to −30 mV to −50 mV, and adsorbs surfactants and organic substances in water. Since coalescence of microbubbles is suppressed by charging, the adsorbed surfactant and organic matter stay in water for a long time. It has also been observed that the permeability of water containing microbubbles is improved.

  The EM active liquid generator 14 includes a tank having a predetermined capacity maintained at a predetermined temperature. When the EM active liquid generator 14 is filled with the water supplied from the water supply, the culture solution in which the useful microorganism group is cultured, and the nutrient source of the useful microorganism group such as molasses and brown sugar, and sealed for about one week, In the EM active solution generator 14, useful microorganisms are cultured to generate an EM active solution. The EM active solution is an example of a medium containing the cultured useful microorganism group, and is supplied to the washing device 11 and the waste water purification device 12.

  In addition, although the EM active liquid is described as an example of the medium containing the cultured useful microorganism group, the medium containing the cultured useful microorganism group is not limited to a liquid, and may be a solid such as a tablet or a powder. You may make it do.

  Next, an example of the configuration of the washing apparatus 11 will be described with reference to FIGS. 2 to 5. FIG. 2 is a cross-sectional view of an example of the washing apparatus 11. The washing apparatus 11 includes a housing 31, a tank 32, a drum 33, a rotating shaft 34, an electric motor 35, a pulley 36, a belt 37, a pulley 38, a water injection unit 39, a water injection pipe 40, a water injection pipe 41, a valve 42, a drain pipe 43, A loading port 44, an instruction unit 45, and an operation unit 46 are provided.

The tank 32 is made of a steel plate such as a so-called stainless steel plate or fiber reinforced plastic, and stores water for washing or rinsing. The tank 32 stores the drum 33 therein.

  The drum 33 is formed in a cylindrical shape (hollow column shape) from a steel plate such as a so-called stainless steel plate or fiber reinforced plastic, and stores a futon to be washed therein. The drum 33 is rotated during washing, rinsing and dewatering. A hole 51 for allowing water to enter and exit is provided in the entire circumference of the drum 33, and a partition wall 52 that divides the space inside the drum 33 along the surface including the rotation shaft 34 is provided inside the drum 33. Is provided.

  When water for washing or rinsing is stored in the tank 32, a part of the drum 33 is immersed in the water stored in the tank 32. In this case, the water stored in the tank 32 enters the space inside the drum 33 from the hole 51 provided in the periphery of the drum 33, and the futon stored inside is immersed in the water.

  The rotating shaft 34 is provided substantially parallel to the water surface of the water stored in the tank 32, and rotatably supports both sides of the circular shape of the cylindrical drum 33.

  That is, when washing or rinsing, the drum 33 rotates around a rotation shaft 34 that is substantially parallel to the water surface of the water stored in the tank 32 so that a part of the drum 33 is immersed in the water stored in the tank 32. Soak the futon stored inside in water.

  In addition, when dewatering, the drum 33 is rotated around the rotating shaft 34 without water being stored in the tank 32, so that the water contained in the futon stored therein is caused by centrifugal force. It is discharged from a hole 51 provided in the periphery of the drum 33.

  The rotation and angular position of the electric motor 35 are controlled by a control unit which will be described later, and the drum 33 is rotated via the pulley 36, the belt 37, and the pulley 38.

The belt 37 is hung on the pulley 36 and the pulley 38, and transmits the rotation of the shaft of the electric motor 35, that is, the rotation of the pulley 36 to the pulley 38. Thereby, if the shaft of the electric motor 35 rotates, the drum 33 rotates.

  The water injection unit 39 selects one of the microbubble water generated and supplied by the microbubble water generation device 13 or the purified water purified and supplied by the waste water purification device 12, and the selected microbubble water or Purified water is poured into the tank 32. The water injection unit 39 includes a valve 53 and a valve 54. The valve 53 and the valve 54 are controlled to be opened and closed by a control unit described later.

  When the micro bubble water is selected, the valve 53 of the water injection unit 39 is opened, and the micro bubble water is injected into the tank 32 through the water injection pipe 40. When purified water is selected, the valve 54 of the water injection unit 39 is opened, and purified water is injected into the tank 32 through the water injection pipe 41.

  The opening and closing of the valve 42 is controlled by a control unit described later. When the valve 42 is closed, either the injected micro bubble water or purified water is accumulated in the tank 32, and when the valve 42 is opened, the water accumulated in the tank 32 is drained through the drain pipe 43. It is discharged from the washing device 11. As described above, the waste water from the washing device 11 is supplied to the waste water purification device 12.

  Thus, water 61 that is either microbubble water or purified water can be stored in the tank 32 as water for washing or rinsing.

  The insertion port 44 is provided in the housing 31 so as to be freely opened and closed, and is an opening for introducing the EM active solution generated by the EM active solution generator 14 into the tank 32 from the outside. That is, the inlet 44 supplies the tank 32 with the EM active solution containing the cultured useful microorganism group.

  The instruction unit 45 is controlled by a control unit which will be described later, and instructs the operator to input the EM active liquid from the input port 44 to the tank 32 when performing the final rinsing among a plurality of times of rinsing. That is, the instruction unit 45 instructs the supply of the EM active liquid from the charging port 44 to the tank 32 when performing the final rinsing. The instruction unit 45 includes a loudspeaker 55 and a light 56. When instructing the operator to input the EM active liquid from the input port 44 to the tank 32, the loudspeaker 55 generates a predetermined sound, and the light 56 continuously emits light or blinks. By doing in this way, even if the worker is away from the washing apparatus 11 or there is noise, it is possible to reliably instruct the worker to input the EM active liquid.

  The operation unit 46 includes a button operated by the worker, a lamp for notifying the worker of the state of the washing apparatus 11, and the like. When the button of the operation unit 46 is operated (pressed) by the operator, a predetermined signal is supplied to a control unit described later. The lamp of the operation unit 46 is caused to emit light by a control unit described later according to the state of the washing device 11.

  Next, the configuration of the drum 33 will be described with reference to FIGS. 3 and 4. FIG. 3 is a perspective view showing a configuration of the drum 33, and FIG. 4 is a cross-sectional view taken along the line AA in FIG. As shown in FIG. 3, a hole 51 for allowing water to enter and exit is provided on the entire circumference of the drum 33. In addition, an openable / closable lid 71 is provided around the drum 33 to store a futon to be washed in the drum 33 and to remove it from the drum 33. In addition, although illustration is abbreviate | omitted, the two lid | covers 71 are provided in the symmetrical position on the basis of the rotating shaft 34. As shown in FIG.

  As shown in FIG. 4, a partition wall 52 that divides the space inside the drum 33 along the surface including the rotation shaft 34 is provided inside the drum 33. 4 indicates the center of rotation of the drum 33. Since two lids 71 are provided at symmetrical positions with respect to the rotating shaft 34, the futons to be washed are stored in the two spaces inside the drum 33 divided by the partition wall 52 from the respective lids 71. can do.

Good. In this case, the number of lids 71 corresponding to the number is provided.

  FIG. 5 is a block diagram illustrating a functional configuration of a control unit that controls each unit of the washing apparatus 11. The control unit 91 can be configured by a relay circuit, a sequencer, or a general-purpose or dedicated microprocessor (computer). When the control unit 91 is configured by a microprocessor (computer), the following functions are realized by executing a predetermined program. That is, the control unit 91 can be configured only by hardware, or can be configured by combining hardware and software.

  The control unit 91 has the functions of the operation panel instruction acquisition unit 101, the water injection control unit 102, the drum control unit 103, the water temperature control unit 104, the drainage control unit 105, the EM active liquid supply instruction control unit 106, and the washing process control unit 107. Have.

  The operation panel instruction acquisition unit 101 acquires a signal supplied from the operation unit 46 when a button on the operation unit 46 is operated (pressed) by an operator, thereby acquiring an instruction by an operation to the operation unit 46. In addition, the operation panel instruction acquisition unit 101 supplies a signal to the operation unit 46 according to the state of the washing device 11 to cause the lamp of the operation unit 46 to emit light.

  The water injection control unit 102 controls the water injection unit 39 to inject microbubble water or purified water into the tank 32 by supplying the water injection unit 39 with a signal for instructing opening / closing of the valve 53 or the valve 54.

  The drum control unit 103 drives the electric motor 35 to control the rotation and angular position of the shaft of the electric motor 35. That is, the drum control unit 103 controls the rotation and the angular position of the shaft of the electric motor 35, thereby rotating and the angular position of the drum 33 via the pulley 36, the belt 37, and the pulley 38 (angular position with respect to the housing 31). To control. For example, the drum control unit 103 stores the futon to be washed in the drum 33 or takes out the washed futon from the drum 33 so that the lid 71 is positioned at a predetermined position with respect to the housing 31. Control the position. For example, when washing or rinsing is performed, the drum control unit 103 rotates the drum 33 in which the futon is stored at a lower rotational speed than in the case of dehydration. Further, for example, when dehydration is performed, the drum control unit 103 rotates the drum 33 in which the futon is stored at a higher rotational speed than in the case of washing or rinsing.

  The water temperature control unit 104 controls the temperature of the water stored in the tank 32 by controlling the injection of hot water or steam from a pipe (not shown) into the tank 32.

  The drainage control unit 105 controls the opening and closing of the valve 42 by supplying a signal instructing opening and closing to the valve 42, and controls the water stored in the tank 32 or the drainage from the tank 32. That is, the drainage control unit 105 controls the opening and closing of the valve 42 so that the injected micro bubble water or purified water is stored in the tank 32 as water for washing or rinsing, or the water stored in the tank 32 is stored. The wastewater is discharged from the washing device 11 as drainage through the drainage pipe 43.

  The EM active liquid supply instruction control unit 106 controls the instruction unit 45 by supplying the instruction unit 45 with a signal instructing output of sound or light emission. The EM active liquid supply instruction control unit 106 causes the instruction unit 45 to output sound or emit light, thereby instructing the operator to input the EM active liquid from the input port 44 to the tank 32 when performing the final rinsing. .

  The washing process control unit 107 responds to the instruction acquired by the operation panel instruction acquisition unit 101, and includes a water injection control unit 102, a drum control unit 103, a water temperature control unit 104, a drainage control unit 105, and an EM active liquid supply instruction control unit 106. By giving instructions to each, the washing apparatus 11 is controlled so that the washing, rinsing, and dehydration steps, which are washing steps, are performed in a preset order and in a preset length (period). To do.

  Next, the waste water purification apparatus 12 will be described with reference to FIG. FIG. 6 is a block diagram showing the configuration of the waste water purification apparatus 12. The waste water purification apparatus 12 has a flow rate adjustment function for storing and transferring a predetermined amount of water quantitatively, and includes a water receiving tank 131, a purification tank 132, a purification tank 133, a precipitation tank 134, and a water storage tank 135. The waste water from the washing device 11 supplied to the waste water purification device 12 is purified by the water receiving tank 131, the purification tank 132, the purification tank 133, and the sedimentation tank 134.

  First, the drainage discharged from the drainage pipe 43 of the washing apparatus 11 is pumped up from a mass provided in the drainage path and supplied to the water receiving tank 131.

  The water receiving tank 131 stores a predetermined amount of waste water from the washing apparatus 11. When the water receiving tank 131 is full, the waste water is discharged as it is by overflow. The water receiving tank 131 is supplied with the EM active liquid generated by the EM active liquid generator 14. In addition, air is blown into the water receiving tank 131 by a blower (air pump) (not shown) in order to supply oxygen necessary for decomposing the organic matter contained in the wastewater by the useful microorganism group contained in the EM active liquid, Moreover, the water receiving tank 131 stirs the waste water stored inside. That is, the water receiving tank 131 is a so-called aeration tank. The water receiving tank 131 also serves as a precipitation separating tank. In the water receiving tank 131, the solid content contained in the waste water is separated, and the solid content is deposited on the bottom of the water receiving tank 131.

  The septic tank 132 and the septic tank 133 are aeration tanks. Since the useful microorganism group of the EM active liquid supplied to the water receiving tank 131 is contained in the water from the water receiving tank 131, air is blown into the septic tank 132 and the clarifying tank 133 by a blower (air pump) (not shown), and the water is stirred. Then, the useful microorganism group decomposes the organic matter contained in the water in the septic tank 132 and the septic tank 133. In addition, the septic tank 132 also serves as a precipitation separation tank, like the water receiving tank 131.

  The sedimentation tank 134 separates the solid content contained in the water, and precipitates the solid content on the bottom of the sedimentation tank 134. The sedimentation tank 134 also serves as an anaerobic filter bed tank. In the sedimentation tank 134, organic matter contained in water is further decomposed by useful microorganisms, and the water is purified.

  The water storage tank 135 stores purified water, which is water purified by the water receiving tank 131, the purification tank 132, the purification tank 133, and the sedimentation tank 134. The purified water stored in the water storage tank 135 is supplied to the washing apparatus 11 through a pipe by a pump (not shown).

  Thus, the waste water purification apparatus 12 purifies the waste water from the washing apparatus 11 using the cultured useful microorganism group. The purified water that has been purified contains a group of useful microorganisms.

  The waste water purification device 12 includes a contact aeration method, a rotating plate contact method, a sprinkling filter bed method, an activated sludge method, an intermittent aeration method, a carrier fluidized biological filtration method, a membrane separation activated sludge method, a batch method, etc. Various purification methods can be employed.

  Next, the microbubble water generator 13 will be described with reference to FIG. FIG. 7 is a block diagram showing the configuration of the microbubble water generator 13.

  The microbubble water generator 13 includes a water tank 151, a valve 152, a pump 153, a microbubble generator 154, and a water supply pump 155. The water tank 151 stores water 161 (microbubble water). The valve 152 injects the water supplied from the water supply into the water tank 151 so that the water 161 (microbubble water) stored in the water tank 151 has a predetermined water level.

  The pump 153 takes in the water 161 from the water tank 151 and supplies the pressurized water 161 to the microbubble generator 154. The microbubble generator 154 generates microbubbles from the water 161 from the pump 153 and the sucked outside air by a gas-liquid mixing swirling method (gas-liquid two-phase high-speed swirling method). Due to the microbubbles generated by the microbubble generator 154, the water 161 stored in the water tank 151 becomes microbubble water which is water containing microbubbles.

  The microbubble generator 154 is not limited to the gas-liquid mixing swirl method, and may be another method such as a pressure dissolution (decompression) method or a shear method.

  The water supply pump 155 supplies the microbubble water in the water tank 151 to the washing device 11.

  Thus, in the micro bubble water production | generation apparatus 13, micro bubble water is produced | generated and supplied to the washing apparatus 11. FIG.

  Next, an example of a washing process will be described with reference to the flowchart of FIG. When the button of the operation unit 46 is operated by the operator and an instruction to start washing is given, in step S11, the washing process control unit 107 responds to the instruction to start washing, which is acquired by the operation panel instruction acquisition unit 101. The microbubble water supplied from the microbubble water generator 13 is poured into the tank 32. More specifically, when the washing process control unit 107 instructs the water injection control unit 102 to inject micro-bubble water, the water injection control unit 102 supplies a signal for instructing the water injection unit 39 to open the valve 53, and the water injection unit 39 valve 53 is opened. Thereby, microbubble water is poured into the tank 32 through the water injection pipe 40. That is, the water injection unit 39 pours microbubble water into the tank 32. In addition, when the washing process control unit 107 instructs the drainage control unit 105 to store water, the drainage control unit 105 supplies a signal for instructing the valve 42 to close, and causes the valve 42 to close. Thereby, microbubble water is stored in the tank 32. Note that when a predetermined amount of microbubble water is stored in the tank 32, the water injection control unit 102 closes the valve 53.

  In step S <b> 12, the operator opens the insertion port 44 and supplies the detergent and the EM active liquid to the tank 32 by introducing the detergent and the EM active liquid generated by the EM active liquid generator 14.

  In step S <b> 13, the washing process control unit 107 rotates the drum 33 in which the futon is stored to wash the futon. That is, the washing process control unit 107 instructs the drum control unit 103 to rotate the drum 33 at the rotation speed set in the washing process. The drum control unit 103 controls the rotation of the drum 33 so that the rotation speed is set in the washing process by driving the electric motor 35 so that the shaft rotates at a rotation speed corresponding to the rotation speed of the drum 33. To do. When the drum 33 rotates, the futon stored in the drum 33 is microbubble water stored in the tank 32 and is immersed in the microbubble water containing the detergent and the useful microorganism group. Will be taken out of. In this way, the drum 33 cleans the futon stored inside.

  The permeability of microbubble water is stronger than that of normal water, so if microbubble water containing microbubbles is used as water for washing, it penetrates more quickly into the futon, thereby making it easier to remove dirt inside the duvet. While being able to remove reliably, the cultured useful microorganism group can be penetrate | infiltrated more reliably inside the futon.

  In particular, when washing a duvet, the strong permeability of microbubble water works more effectively. In other words, in order to prevent the included feathers from going out, and to prevent contamination of the included feathers, the side fabric (side fabric) of the duvets is made of a fabric with clogged eyes. , It is difficult for water to penetrate into the duvet. When microbubble water is used for washing the duvet, the detergent and the microorganism group can be more reliably infiltrated into the duvet more quickly.

  In step S14, the washing process control unit 107 rotates the drum 33 in which the futon is stored to dehydrate the futon. More specifically, the washing process control unit 107 instructs the drainage control unit 105 to drain, and also instructs the drum control unit 103 to rotate the drum 33 at the rotation speed set in the dehydration process. Accordingly, the drainage control unit 105 supplies a signal for instructing the valve 42 to open, and causes the valve 42 to open. As a result, the water stored in the tank 32 is drained. Further, the drum controller 103 drives the electric motor 35 so that the shaft rotates at a rotational speed corresponding to the rotational speed of the drum 33, so that the rotational speed of the drum 33 is set to the rotational speed set in the dehydration process. To control. The drum 33 rotates at a higher rotational speed than in the case of washing or rinsing, and water contained in the futon stored in the drum 33 is discharged by centrifugal force.

  In step S <b> 15, the washing process control unit 107 causes the purified water supplied from the waste water purification device 12 (containing useful microorganisms) to be poured into the tank 32. More specifically, when the washing process control unit 107 instructs the water injection control unit 102 to inject purified water, the water injection control unit 102 supplies a signal for instructing the water injection unit 39 to open the valve 54, and the water injection unit 39. The valve 54 is opened. Thereby, purified water is poured into the tank 32 through the water injection pipe 41. That is, the water injection part 39 injects purified water into the tank 32. In addition, when the washing process control unit 107 instructs the drainage control unit 105 to store water, the drainage control unit 105 supplies a signal for instructing the valve 42 to close, and causes the valve 42 to close. Thereby, purified water is stored in the tank 32. When a predetermined amount of purified water is stored in the tank 32, the water injection control unit 102 closes the valve 54.

  In step S <b> 16, the washing process control unit 107 rotates the drum 33 in which the futon is stored, and rinses the futon with the purified water stored in the tank 32. That is, the washing process control unit 107 instructs the drum control unit 103 to rotate the drum 33 at the rotation speed set in the rinsing process. The drum controller 103 controls the rotation of the drum 33 so that the rotation speed set in the rinsing process is achieved by driving the electric motor 35 so that the shaft rotates at a rotation speed corresponding to the rotation speed of the drum 33. To do. When the drum 33 rotates, the futon stored in the drum 33 is purified water stored in the tank 32, soaked in purified water containing useful microorganisms, and removed from the purified water. . In this way, the drum 33 rinses the futon stored inside. In rinsing, the drum 33 may be rotated every predetermined angle, or the drum 33 may be rotated in the opposite direction every predetermined time.

  In step S <b> 17, the washing process control unit 107 rotates the drum 33 storing the futon inside to weakly dehydrate the futon. More specifically, the washing process control unit 107 instructs the drainage control unit 105 to drain, and also instructs the drum control unit 103 to rotate the drum 33 at the rotation speed set in the weak dehydration process. Accordingly, the drainage control unit 105 supplies a signal for instructing the valve 42 to open, and causes the valve 42 to open. As a result, the water stored in the tank 32 is drained. Furthermore, the drum control unit 103 drives the electric motor 35 so that the shaft rotates at a rotation speed corresponding to the rotation speed of the drum 33, so that the rotation speed of the drum 33 is set to the rotation speed set in the weak dehydration process. Control the rotation. The drum 33 rotates at a higher rotational speed than that in the case of washing or rinsing, and is lower than that in the case of dehydration in step S14, and is included in the futon stored in the drum 33. Water is discharged by centrifugal force.

  In step S <b> 18, the washing process control unit 107 causes the purified water supplied from the waste water purification apparatus 12 to be poured into the tank 32 as in the process of step S <b> 15.

  In step S <b> 19, as in the process of step S <b> 16, the washing process control unit 107 rotates the drum 33 in which the futon is stored, and rinses the futon with the purified water stored in the tank 32.

  In step S20, the washing process control unit 107 rotates the drum 33 in which the futon is stored in the same manner as in the process of step S17 to weakly dehydrate the futon. In step S20, the dehydrated water contained in the futon can be cut off (by removing the purified water from the futon) by weak dehydration, and the microbubble water and the EM active liquid in the subsequent steps S21 to S24 are used. The effect of rinsing can be further enhanced.

  In step S <b> 21, the washing process control unit 107 causes the microbubble water supplied from the microbubble water generator 13 to be poured into the tank 32, as in the process of step S <b> 11.

  In step S <b> 22, the washing process control unit 107 instructs the supply of the EM active liquid to the tank 32. That is, when the washing process control unit 107 instructs the EM active liquid supply instruction control unit 106 to supply the EM active liquid to the tub 32, the EM active liquid supply instruction control unit 106 outputs a signal for instructing sound output and light emission. Is supplied to the instruction unit 45. The instruction unit 45 generates a predetermined sound from the loudspeaker 55 and causes the light 56 to emit light or blink, thereby instructing the operator to input the EM active liquid.

  In step S <b> 23, the operator opens the charging port 44, loads the EM active liquid generated by the EM active liquid generator 14 into the tank 32 from the outside, and closes the charging port 44. That is, in step S <b> 23, the EM active solution is supplied to the tank 32 through the input port 44.

  In step S <b> 24, the washing process control unit 107 rotates the drum 33 in which the futon is stored, and rinses the futon with microbubble water containing the cultured group of useful microorganisms stored in the tank 32. That is, the washing process control unit 107 instructs the drum control unit 103 to rotate the drum 33 at the rotation speed set in the rinsing process. The drum controller 103 controls the rotation of the drum 33 so that the rotation speed set in the rinsing process is achieved by driving the electric motor 35 so that the shaft rotates at a rotation speed corresponding to the rotation speed of the drum 33. To do. When the drum 33 rotates, the futon stored in the drum 33 is microbubble water stored in the tank 32, soaked in microbubble water containing useful microorganisms, and taken out from the microbubble water. It will be. In this way, the drum 33 rinses the futon stored inside. In the rinsing in step S24, the drum 33 may be rotated every predetermined angle, or the drum 33 may be rotated in the opposite direction every predetermined period.

  When the drum 33 is washed or rinsed, the drum 33 rotates about a rotation axis 34 substantially parallel to the water surface of the water stored in the tank 32 so that a part of the drum 33 is immersed in the water stored in the tank 32. Because the futon stored in the bag is immersed in water, it can be washed or rinsed with less water. As a result, more useful microorganism groups can be attached to the futon with respect to the amount of useful microorganism groups contained in the EM active solution supplied to the tank 32.

  In addition, the drum 33 is provided with partition walls 52 that divide the space inside the drum 33 along the surface including the rotation shaft 34, and the futons are stored in the respective spaces. Is surely immersed in the water stored in the tank 32. Further, since the space for storing the futon becomes small, even if the drum 33 rotates, the futon becomes difficult to move in the drum 33, and as a result, the futon is hardly damaged.

  In step S <b> 25, the washing process control unit 107 drains the water stored in the tub 32. That is, the washing process control unit 107 instructs the drainage control unit 105 to drain. Accordingly, the drainage control unit 105 supplies a signal for instructing the valve 42 to open, and causes the valve 42 to open. Thereby, the water stored in the tank 32 is drained.

  In step S26, the washing process control unit 107 rotates the drum 33 in which the futon is stored to dehydrate the futon, and the washing is finished. More specifically, in step S26, the washing process control unit 107 instructs the drum control unit 103 to rotate the drum 33 at the rotation speed set in the dehydration process. The drum control unit 103 controls the rotation of the drum 33 so that the rotation speed is set in the dehydration process by driving the electric motor 35 so that the shaft rotates at a rotation speed corresponding to the rotation speed of the drum 33. To do. The drum 33 rotates at a higher rotational speed than in the case of washing or rinsing, and water contained in the futon stored in the drum 33 is discharged by centrifugal force.

  As described above, when the final rinsing is performed among a plurality of times of rinsing, the EM active solution containing the cultured useful microorganism group is supplied to the tank 32. Since the EM active solution is supplied to the tank 32 at the final rinse, more cultured microorganism groups remain in the futon, and the propagation of microorganisms that generate malodors can be suppressed for a longer period of time. It becomes possible to prevent the generation of malodor for a longer period.

  When the duvet is washed, it is possible to suppress the propagation of microorganisms that generate a bad odor or the like for a longer time than when performing conventional washing.

  The surface of the feathers contained in the duvet is composed of keratin protein covered with natural grease. Since this natural grease is prone to wrinkles and has a strong smell of wild birds, when it is used for a duvet, a natural grease is previously removed using a surfactant. However, when natural grease is removed, bacteria are likely to attach to the feathers.

  Pseudomonas aeruginosa (Pseudomonas aeruginosa), Serratia marcescens (Serratia marcescens), Alcaligenes bukeri (Alcaligenes bookeri: Bacillus subtilis), etc. is there. They break down the keratin protein on the surface of the feathers and generate odors and odors.

  When the EM active liquid containing the cultured useful microorganism group is supplied to the tank 32 when rinsing the last of the plurality of rinses, the useful microorganism group cultured in the feathers included in the duvet. As a result, it is possible to suppress the growth of bacteria and spiders that generate malodors and the like for a longer period of time, and to prevent the generation of malodors for a longer period of time.

  In the final rinsing, microbubble water containing microbubbles is poured into the tank 32 as water for rinsing. Microorganisms that generate malodors or the like because the cultured useful microorganism group contained in the EM active solution supplied to the tank 32 at the last rinse is more activated (acts more actively) by the oxygen of the microbubbles. It will be possible to more strongly suppress the breeding.

  In addition, the side fabric (side fabric) of the duvet uses a clogged fabric to prevent the contained feathers from going out and to prevent the contained feathers from becoming dirty. It is difficult for water for rinsing to penetrate. Since the permeability of microbubble water is stronger than that of normal water, the use of microbubble water containing microbubbles as water for rinsing in the final rinsing more reliably removes dirt inside the futon. At the same time, the cultured useful microorganism group can be more reliably permeated into the futon.

  Moreover, when the waste water from the washing apparatus 11 is purified using the cultured group of useful microorganisms, the purified water purified by the waste water purification apparatus 12 is rinsed when rinsing other than the last rinse is performed among a plurality of rinses. Since water is poured into the tank 32 as water for use, by circulating the water, the amount of clean water used is further reduced, and more useful microorganisms contained in the purified water remain in the futon. Thus, the generation of malodor can be prevented for a longer period by suppressing the propagation of microorganisms that generate malodor or the like for a longer period.

  Furthermore, since the EM active solution containing the cultured useful microorganism group is supplied to the tank 32 when washing the futon, more useful microorganism groups can be permeated into the futon, and microorganisms that generate malodor etc. By suppressing the breeding of the animal for a longer period, the generation of malodor can be prevented for a longer period.

  Furthermore, when washing the futon, the microbubble water containing microbubbles is poured into the tank 32 as washing water, so that the detergent and the microorganism group can be surely infiltrated into the futon. Even if the clogged fabric is a duvet used for a side fabric (side fabric), the detergent and the microorganism group can be more reliably infiltrated into the interior. In this case, the oxygen dissolved by the microbubbles increases the activity of the useful microorganism group, so that the growth of microorganisms that generate malodors can be suppressed for a longer period and the generation of malodors can be prevented for a longer period.

  Next, with reference to the flowchart of FIG. 9, the purification of waste water in the waste water purification apparatus 12 will be described. In step S51, it is determined whether one day has passed since the previous supply of the EM active solution. If it is determined that one day has passed, the process proceeds to step S52, and the EM active solution is supplied to the water receiving tank 131. Is done. After step S52, the process proceeds to step S53. The supply of the EM active liquid to the water receiving tank 131 may be performed by an operator, or may be performed using a supply device that supplies the chemical liquid regularly and quantitatively.

  If it is determined in step S51 that one day has not elapsed, step S52 is skipped, the supply of the EM active liquid to the water receiving tank 131 is not performed, and the process proceeds to step S53.

  In step S <b> 53, the waste water from the washing device 11 is pumped from the mass to the water receiving tank 131. In step S54, the waste water is purified by the cultured useful microorganism group contained in the EM active liquid in the aerated water receiving tank 131. The drainage of the water receiving tank 131 is allowed to flow in order to the septic tank 132, the septic tank 133, the sedimentation tank 134, and the water storage tank 135 in a fixed amount per predetermined period.

  In step S55, water is purified by a group of useful microorganisms contained in the water flowing from the water receiving tank 131 in the septic tank 132 and the septic tank 133 that are aerated. In step S56, solids are separated from water in the precipitation tank 134, and the water is purified by a group of useful microorganisms contained in the water. In step S57, purified water, which is purified water, is stored in the water storage tank 135.

  In step S58, the purified water stored in the water storage tank 135 is supplied to the washing apparatus 11 through the pipe, and the process returns to step S51 to repeat the above steps.

  Thus, in each of the water receiving tank 131, the septic tank 132, the septic tank 133, and the sedimentation tank 134, the waste water from the washing apparatus 11 is purified using the cultured useful microorganism group. As described above, the purified water supplied to the washing apparatus 11 is poured into the tub 32 as water for rinsing when rinsing other than the final rinsing is performed among a plurality of rinsings. Therefore, the amount of clean water used can be further reduced.

  Further, the EM active solution generated by the EM active solution generator 14 can be automatically injected into the tank 32.

Since the casing 31 to the operation unit 46 shown in FIG. 10 are the same as those shown in FIG.

  The opening and closing of the valve 181 is controlled by the EM active liquid supply instruction control unit 106 of the control unit 91. When the valve 181 is opened, the EM active liquid supplied from the EM active liquid generator 14 is injected into the tank 32 via the water injection pipe 182 via a pressure feed pump, piping, etc. (not shown).

  In addition, you may make it inject | pour EM active liquid into the tank 32 using a fixed valve, a fixed supply apparatus, etc. FIG.

  Next, another example of the washing process will be described with reference to the flowchart of FIG. Since the process of step S81 is the same as the process of step S11 of FIG. 8, the description thereof is omitted.

  In step S <b> 12, the operator opens the opening provided in the housing 31 in order to put the laundry into the drum 33, and supplies the detergent to the tub 32 by introducing the detergent.

  In step S <b> 83, the washing process control unit 107 injects (supplies) the EM active liquid into the tank 32. That is, when the washing process control unit 107 instructs the EM active liquid supply instruction control unit 106 to inject (supply) the EM active liquid into the tank 32, the EM active liquid supply instruction control unit 106 outputs a signal instructing opening. Supply to the valve 181 to open the valve 181. As a result, the EM active liquid is injected into the tank 32 through the water injection pipe 182. In other words, the valve 181 injects the EM active liquid into the tank 32. A desired amount of the EM active liquid is injected into the tank 32 by controlling the flow rate per hour of the EM active liquid and the time during which the valve 181 is opened.

  Steps S84 to S92 are the same as steps S13 to S21 in FIG.

  The steps S94 to S96 are the same as the steps S24 to S26 in FIG.

  As described above, the EM active solution generated by the EM active solution generator 14 can be automatically injected into the tank 32.

  As described above, since the group of useful microorganisms cultured in the last rinse water of the plurality of rinses is included, more cultured microorganism groups remain in the futon and generate malodors, etc. By suppressing the growth of microorganisms to be caused for a longer period, generation of malodor can be prevented for a longer period.

  In this way, when rinsing the last of a plurality of rinsings, the water for rinsing is pooled, and the medium containing the cultured group of useful microorganisms is put into the pooled water for rinsing. In this case, the generation of malodor can be prevented for a longer period by suppressing the propagation of microorganisms that generate malodor or the like for a longer period.
