Description

The present invention relates to a cleaning method for washing an object to be cleaned with water.

Commercially used cleaning methods include washing with water (also called laundry or wet cleaning) and dry cleaning using an organic solvent instead of water. Dry cleaning is less likely to cause shrinkage and wrinkles on the object to be cleaned, but has the disadvantages of causing skin problems due to the solvent remaining on the object to be cleaned, giving off an unpleasant odor from the object to be cleaned, and making it difficult to remove water-soluble stains. is there. Washing with water has the disadvantage that the object to be cleaned (especially when the object to be cleaned is made of natural materials such as cotton, wool, silk, linen) shrinks, loses its shape, and changes its texture.

The following Patent Documents 1 and 2 propose a method for suppressing the drawbacks of washing with water. Specifically, Patent Document 1 proposes a method of directly spraying a processing agent (shrink-proof processing agent, softening processing agent, gloss processing agent) onto laundry after a rinsing / dehydrating step or during a rinsing / dehydrating step. doing. Further, in Patent Document 2, the temperature in the washing step is set to 15 ° C. or higher and lower than 40 ° C. We are proposing a method that increases the operation time by 20 times.

However, when the object to be cleaned of a natural material is washed with water, even if the methods of Patent Documents 1 and 2 are adopted, there is a problem that it is difficult to suppress the occurrence of quality deterioration such as shrinkage, texture change, and color transfer.

The present invention has been made in view of the above problems, and in a cleaning method for washing a cleaning target of a natural material with water, a cleaning method capable of sufficiently removing stains and suppressing the occurrence of quality deterioration such as shrinkage, texture change, and color transfer. The challenge is to provide.

In order to solve the above problems, the cleaning method of the present invention
A pretreatment process that pretreats the object to be cleaned made of natural materials with a stain remover,
An overall protection step of wrapping the entire cleaning target after the pretreatment step with a cloth,
A cleaning step in which the cleaning target wrapped in the cloth is placed in a washing tub, a washing detergent and a quality protective agent are added to the washing tub, and the cleaning target is washed with water.
An intermediate dehydration step in which dehydration is performed after the washing step, and
After the intermediate dehydration step, the quality protective agent is added to the washing tub again, and the cleaning target is rinsed with water.
The final dehydration step, in which dehydration is performed after the rinse step, and
To be equipped.

According to the present invention, since the cleaning target is pretreated with a stain remover before the cleaning step, stains (dirt) on the cleaning target can be sufficiently removed. Further, by pretreating with a stain remover, the time of the subsequent cleaning step can be shortened. As a result, the load applied to the cleaning target in the cleaning process can be reduced, and deterioration of the quality of the cleaning target can be suppressed. Further, in the present invention, since each step after the cleaning step is performed in a state where the entire cleaning target is wrapped with a cloth, it is possible to prevent another color from being transferred to the cleaning target. Further, since it is possible to prevent the inner wall of the washing tub from coming into direct contact with the cleaning target, it is possible to prevent the cleaning target from being damaged or entangled.

Further, in the present invention, since the quality protective agent is added in both the cleaning step and the rinsing step, deterioration of the quality of the object to be cleaned can be further suppressed. Further, in the present invention, since the intermediate dehydration step is performed between the cleaning step and the rinsing step, the detergent and dirt remaining on the cleaning target can be removed to some extent together with the moisture in this intermediate dehydration step. As a result, the detergent and dirt remaining on the cleaning target can be sufficiently removed in the subsequent rinsing step. Further, by removing the detergent and dirt remaining on the cleaning target to some extent before the rinsing process, the time of the subsequent rinsing process can be shortened. As a result, the load applied to the cleaning target in the rinsing process can be reduced, and deterioration of the quality of the cleaning target can be suppressed.

The present invention may include a partial protection step of partially covering the cleaning target with a cloth before the overall protection step. According to this, the portion covered with the cloth can be further protected, and quality deterioration such as transfer of another color to the portion can be further suppressed.

In the present invention, the cloth may be a cotton cloth. Cotton cloth has the property of being easily dyed in color. By protecting the object to be cleaned with a cotton cloth, the dye can be blocked by the cotton cloth and the color transfer to the object to be cleaned can be further suppressed. In addition, since the cotton cloth allows water to pass through well, it is possible to sufficiently remove the dirt adhering to the object to be cleaned by the water.

The present invention may include a net protection step of wrapping the cleaning object wrapped in the cloth with a net after the whole protection step and before the cleaning step. According to this, since the cleaning target is wrapped with both the cloth and the net, it is possible to further prevent the cleaning target from being damaged or entangled.

In the present invention, in the cleaning step, as the quality protective agent, a first detergent having a shrinkage-proofing or wrinkle-proofing effect, a second detergent having a texture-protecting effect, and an effect of preventing color transfer or discoloration are provided. A third detergent may be added, and the first detergent and the second detergent may be added in the rinsing step. As a result, it is possible to suppress the occurrence of quality deterioration such as shrinkage, wrinkles, texture change, color transfer, and discoloration on the object to be cleaned.

The first detergent may be a detergent containing silicone, poly (oxyethylene) = alkyl = ether (C = 12-15), anionic polymer, amide compound, isopropyl alcohol, and water. Specific examples of the detergent satisfying this component include Softil (registered trademark), which is a shrink-proof / anti-wrinkle agent manufactured by NICCA CHEMICAL CO., LTD.

The second detergent may be a detergent containing silicone, poly (oxyethylene) = alkyl = ether (C = 12-15), a cationic surfactant, an organic acid, a glycol solvent, and water. Specific examples of the detergent satisfying this component include Famiton (registered trademark) DX-10, which is a wet finishing agent manufactured by NICCA CHEMICAL CO., LTD. Famiton (registered trademark) DX-10 is a detergent for giving a soft texture to a cleaning object.

The third detergent may be alum or citric acid. Alum is potassium aluminum sulphate.

By using the first detergent, the second detergent, and the third detergent that satisfy the above components, the present inventor causes quality deterioration such as shrinkage, wrinkles, texture change, color transfer, and discoloration on the object to be cleaned. It has been confirmed that it was possible to suppress.

In the present invention, the stain remover may be an oxygen-based bleach. As a result, stains on the cleaning target can be effectively removed.

In the washing step in the present invention, the quality protective agent may be added to the washing tub before water is added to the washing tub. According to this, in the cleaning process, the quality protective agent can be applied to the object to be cleaned before water is added. As a result, the quality protective agent can be easily applied to the cleaning target, and the quality deterioration of the cleaning target can be further suppressed.

In the present invention, the time of each step of the washing step, the intermediate dehydration step, and the rinsing step may be 30 seconds or more and less than 3 minutes, and the time of the final dehydration step may be 30 seconds or more and less than 4 minutes. In this way, by setting the time of each step to less than 3 minutes (in the case of the cleaning step, the intermediate dehydration step, and the rinsing step) or less than 4 minutes (in the case of the final dehydration step), the load applied to the cleaning target in each step can be reduced. It can be made smaller, and deterioration of the quality of the object to be cleaned can be further suppressed. In addition, the washing of the object to be cleaned can be completed in a short time. Further, by setting the time of each step to 30 seconds or more, it is possible to prevent the effects of each step, that is, the cleaning effect, the rinsing effect, and the dehydration effect from becoming insufficient.

In the washing step and the rinsing step in the present invention, the washing tub is rotated in the forward direction at a speed of 25 rpm or more and 40 rpm or less, then stopped for a predetermined time, and then rotated in the reverse direction at a speed of 25 rpm or more and 40 rpm or less. Repeat the operation,
In the intermediate dehydration step, the maximum rotation speed of the washing tub is set to 200 rpm or more and 600 rpm or less.
In the final dehydration step, the maximum rotation speed of the washing tub may be 400 rpm or more and 600 rpm or less. In addition, rpm is an abbreviation for revolutions per minute.

By setting the rotation speed of the washing tub to 40 rpm or less in the washing step and the rinsing step, it is possible to prevent the cleaning target from being damaged or entangled during the washing step or the rinsing step. Further, by setting the rotation speed of the washing tub to 25 rpm or more, the washing effect and the rinsing effect can be obtained in a short time. Since the cleaning process and the rinsing process can be performed in a short time, it is possible to suppress the occurrence of quality deterioration of the cleaning target. Further, in the washing step and the rinsing step, the washing effect and the rinsing effect can be effectively obtained while suppressing the rotation speed of the washing tub by repeating the forward and reverse rotation of the washing tub. In addition, by setting a stop period between the forward rotation and the reverse rotation, it is possible to prevent the cleaning target from swaying randomly in the washing tub, which in turn prevents the cleaning target from being damaged or entangled. Can be suppressed.

Further, by setting the rotation speed of the washing tub in the intermediate dehydration step and the final dehydration step to 600 rpm or less, it is possible to prevent the cleaning target from being damaged or entangled during dehydration. Further, by setting the rotation speed in the intermediate dehydration step to 200 rpm or more, the detergent and dirt adhering to the cleaning target can be removed to some extent together with water, and the intermediate dehydration step time can be shortened. Further, a sufficient dehydration effect can be obtained by setting the rotation speed in the final dehydration step to 400 rpm or more. As a result, it is possible to prevent water from dripping from the object to be cleaned during drying after the final dehydration step, and it is possible to prevent the color from fading with the water.

It is a flowchart of a cleaning method. It is the figure of the state which the cleaning object is placed on the cotton cloth, and the cloth is partially applied to the cleaning object. It is the figure of the state that the whole cleaning object was wrapped with the cotton cloth. It is the figure of the state which the cleaning object wrapped in the cloth is put in the net. It is the figure of the state which connected the surplus part of the net which put the object to be cleaned. It is a block diagram of the schematic structure of a washing machine. It is a flowchart which shows the specific procedure of step S7 of FIG. It is a flowchart which shows the specific procedure of step S9 of FIG.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a flowchart of a cleaning method of the present embodiment. The cleaning method of FIG. 1 may be carried out commercially by a cleaning company or may be carried out at home. In the method of FIG. 1, first, one or a plurality of objects (cleaning objects) to be cleaned (washed) are prepared (S1). The object to be cleaned is, for example, clothing made of natural materials such as cotton, wool, silk, leather, and linen, in other words, at least a part of animal-derived fibers or leather or plant-derived fibers. Included clothing, etc. When preparing a plurality of cleaning targets, cleaning targets of materials or colors similar to each other may be prepared, or cleaning targets of different materials or colors may be prepared.

Next, each cleaning target prepared in step S1 is pretreated with a stain remover (S2). The stain remover is, for example, an oxygen-based bleach. By treating with an oxygen-based bleach, stains (for example, oil-based stains) adhering to the object to be cleaned can be effectively removed. In addition, since oxygen-based bleach has a slower bleaching action than chlorine-based bleach, it is possible to prevent the cleaning target from being damaged by the action of the bleaching agent, and it is also possible to suppress the decomposition of the dye to be cleaned. .. Examples of the oxygen-based bleach include "Wide Higher (registered trademark)" manufactured by Kao Corporation. Wide Higher (registered trademark) includes water (process agent), polyoxyethylene alkyl ether (surfactant), hydrogen peroxide (oxygen-based) (bleaching agent), alkylammonium salt (surfactant), etidronate (surfactant). Detergent containing metal sequestering agent), etidronic acid (metal sequestering agent), silicone (foam adjusting agent), and fragrance (fragrance). Wide Higher® is an acidic bleach (in other words, an oxidative bleach).

Specifically, step S2 is performed as follows. That is, as shown in FIG. 2, first, a cotton cloth 2 (in other words, sheets) is prepared, and the prepared cloth 2 is laid on a flat surface. The cloth 2 is preferably a cloth that is not colored with a dye or a cloth 2 that is colored with a light color. Further, the cloth 2 may be prepared for each cleaning target, but one cloth 2 may be prepared for a plurality of cleaning targets.

Next, the cleaning target 1 (see FIG. 2) is placed on the cloth 2 in a spread state. In FIG. 2, a kimono is illustrated as a cleaning target 1. Next, a liquid oxygen-based bleach (for example, Wide Higher (registered trademark)) is attached to the cleaning target 1. Specifically, for example, a liquid oxygen-based bleach is placed in a spray container, and the oxygen-based bleach is sprayed toward the cleaning target 1 from the injection port of the spray container. Further, the oxygen-based bleach may be attached to a part of the cleaning target 1 (a portion to which stains are attached or a portion to which stains are likely to be attached), or may be attached to the entire cleaning target 1. Further, it is preferable that the oxygen-based bleach adheres not only to the outer surface (in other words, the outer material) of the cleaning target 1 but also to the inner surface (in other words, the lining). By adhering the oxygen-based bleach by spraying in this way, the oxygen-based bleach can be easily adhered to a part or the whole of the object to be cleaned.

Next, during or after pretreatment with an oxygen-based bleach, a portion of the cleaning target 1 that requires special protection (for example, a portion where color transfer is likely to occur, a portion where color transfer is conspicuous (light-colored portion)), Cover the parts that are easily discolored (bleached), the parts that are easily damaged, etc.) with a cotton cloth 3. In other words, the cleaning target 1 is partially covered with the cloth 3 (see FIG. 2). As with the cloth 2 laid first, the cloth 3 is preferably a cloth that is not colored with a dye or a cloth that is colored with a light color. As shown in FIG. 2, the portion to be applied with the cloth 3 may be a plurality of portions. Further, the portion to be applied is, for example, a portion that does not come into direct contact with the cloth 2 when the entire cleaning target 1 is wrapped with the cloth 2 in step S4 described later, specifically, for example, the inner surface of the cleaning target 1 (for example, the inner surface of the cleaning target 1. In other words, it can be a lining (for example, around the collar). The step S3 is a partial protection step of partially protecting the cleaning target 1 with the cloth 3.

Next, the entire cleaning target 1 in which steps S2 and S3 have been performed is wrapped with the cloth 2 laid first (S4). At this time, the cloth 2 and the cleaning target 1 (including the cloth 3 that partially protects the cleaning target 1) placed on the cloth 2 can be finally put into the net 4 (see FIG. 4) described later while being folded into small pieces. Make it the size. FIG. 3 shows a state in which the entire cleaning target 1 is covered with the cloth 2. The step S4 is an overall protection step of protecting the entire cleaning target 1 with the cloth 2.

In step S4, when there are a plurality of cleaning targets, it is preferable to wrap each cleaning target with one cloth 2, but the plurality of cleaning targets may be collectively wrapped with one cloth 2. In this case, in order to suppress color transfer between a plurality of cleaning targets, the cleaning targets made of the same color material or the cleaning targets made of a material that does not easily fade are collectively used with the cloth 2. It is good to wrap it.

Next, as shown in FIGS. 4 and 5, the entire cleaning target 1 covered with the cloth 2 is wrapped with the net 4 (S5). Specifically, as shown in FIG. 4, a bag-shaped net 4 is prepared, and a cleaning target 1 covered with a cloth 2 is placed in the net 4. The net 4 is formed of a net-like material made of a synthetic resin such as polyester.

After that, if a fastener is provided at the mouth portion 4a (see FIG. 4) of the net 4, the fastener is closed. When the mouth portion 4a of the net 4 is not provided with a fastener, the portion around the mouth portion 4a of the net 4 is tied so as to close the mouth portion 4a, and the net 4 is formed with a knot 4b (see FIG. 5). ). Further, even when the mouth portion 4a is provided with the fastener, if the net 4 has a surplus portion in the state where the cleaning target 1 is put in the net 4, the surplus portion should be reduced. Connect the surplus part of the net 4 to (see FIG. 5). By connecting the net 4 in this way, it is possible to prevent the cleaning target 1 from popping out from the net 4 during washing described later, and it is possible to prevent the cleaning target 1 from moving around randomly in the net 4. ..

It is preferable to put one cleaning target 1 in one net 4, but one cleaning target 1 made of the same color material or one cleaning target 1 made of a material that is difficult to decolorize is one net. You may put it in 4. In this case, the plurality of cleaning objects 1 placed in one net 4 are preferably wrapped in separate cloths 2, but may be wrapped in the same cloth 2.

Next, the cleaning target 1 placed in the net 4 is left for a certain period of time (S6). The leaving time is, for example, 1 minute to 10 minutes. As a result, the stain remover adhering to the cleaning target 1 in step S2 can be blended (penetrated) into the cleaning target 1, and the stain removing effect can be improved. The step S6 may be left at any timing after step S2 and before the cleaning step of step S10, in other words, after a certain period of time (1 minute to 10 minutes) has elapsed since step S2 was performed. It means that step S9 (cleaning step) is carried out.

After that, the cleaning target 1 placed in the net 4 is washed with a washing machine (S7 to S13). Here, FIG. 6 shows a block diagram of a schematic configuration of a washing machine for performing steps S7 to S13. The washing machine 10 in FIG. 6 is, for example, a drum-type washing machine. Further, the washing machine 10 can set conditions such as the time of each step of steps S10 to S13 and the rotation mode (rotation speed, etc.) of the drum in advance, and automatically performs each step according to the preset conditions. It is configured as a fully automatic washing machine. Specifically, the washing machine 10 includes a washing tub 11 (drum), a driving unit 12 for rotating the washing tub 11, a detergent accommodating unit 13, a charging control member 14, and a driving unit for driving the charging control member 14. It includes 15, a setting unit 16 for performing various settings, and a control unit 17 for controlling the drive units 12, 15, and the like.

The washing tub 11 is formed in a bottomed cylindrical shape, and is provided so that the central axis of the washing tub 11 faces in a substantially horizontal direction. A rotating shaft that can rotate around the central axis of the washing tub 11 is connected to the washing tub 11. The washing tub 11 rotates around a rotation axis to wash, rinse or dehydrate the object to be cleaned.

The drive unit 12 is an actuator (motor or the like) that is connected to the rotation shaft of the washing tub 11 and rotates the rotation shaft. The detergent accommodating portion 13 is configured as a container capable of accommodating detergent. The charging control member 14 is a member for automatically charging the container (detergent) of the detergent storage unit 13 into the washing tub 11 at a preset timing. The charging control member 14 is in a charging permission state in which the container (detergent) of the detergent storage unit 13 is charged into the washing tub 11, and the storage material (detergent) is not charged into the washing tub 11 but into the storage unit 13. It is provided so that it can be switched between the state in which the input is prohibited to stay.

The drive unit 15 is an actuator (motor or the like) that is connected to the closing control member 14 and changes the closing control member 14 between the closing permitted state and the closing prohibited state.

The setting unit 16 is a part for setting various settings such as the time of each step of steps S10 to S13, the rotation mode (rotation speed, etc.) of the washing tub 11, the amount of water to be charged into the washing tub 11. Further, the setting unit 16 can also set the timing of charging the detergent stored in the detergent storage unit 13 into the washing tub 11. The setting unit 16 is configured as a switch or a touch panel on which the setting operation is performed by the user.

The control unit 17 controls the drive units 12 and 15 so that the washing tub 11 and the charging control member 14 are driven according to the conditions set in advance by the setting unit 16, and controls the water supply or drainage to the washing tub 11. To do.

In washing with the washing machine 10, the user first operates the setting unit 16 to set the conditions for each step of steps S10 to S13 (S7). Specifically, for example, the conditions for each step are set according to the procedure shown in FIG. In FIG. 7, first, as the conditions in the washing step of step S10, the washing step time, the amount of water to be put into the washing tub 11, and the rotation mode of the washing tub 11 are set (S21). The cleaning step time is preferably 30 seconds or more and less than 3 minutes (for example, 2 minutes). Dirt may not be sufficiently removed in less than 30 seconds. If it is 3 minutes or more, the cleaning target may be damaged or entangled due to a long load applied to the cleaning target. The amount of water should be set to a medium water level with respect to the maximum water level of the washing tub 11. The medium water level means 40% to 70% of the maximum water level. If the water level is less than 40% of the maximum water level, dirt may not be sufficiently removed (cleaning effect is small). If the water level is higher than 70% of the maximum water level, the degree of swelling of the cleaning target by water increases, and the degree of wrinkles and shrinkage occurring in the cleaning target may increase.

Further, as a rotation mode of the washing tub 11 in the washing step, it is set to repeat the operation of rotating the washing tub 11 in the forward direction for the first hour, then stopping the washing tub 11 for the second hour, and then rotating the washing tub 11 in the reverse direction for the third hour. To do. At this time, it is preferable to set a speed of 25 rpm or more and 40 rpm or less as the rotation speed when rotating the washing tub 11 in the forward direction or the reverse direction. Dirt may not be sufficiently removed below 25 rpm. If it is higher than 40 rpm, the load on the cleaning target becomes large, and the cleaning target may be damaged or entangled. When three speeds (low rotation, medium rotation, high rotation) can be set as the rotation speed in the cleaning step, it is preferable to set it to "medium rotation". Dirt may not be sufficiently removed at low speeds. At high speeds, the load on the cleaning target increases, and the cleaning target may be damaged or entangled.

Further, as the first time and the third time, for example, it is preferable to set a time of 1 second or more and 10 seconds or less. If it is less than 1 second, the degree of shaking of the cleaning target in the washing tub 11 is small, and there is a possibility that dirt is not sufficiently removed. If it is longer than 10 seconds, the number of times the cleaning target swings in the washing tub 11 in the forward direction and the reverse direction within the washing process time decreases, and the dirt removing effect due to the swing becomes small.

Further, as the second time, for example, it is preferable to set a time of 1 second or more and 10 seconds or less. In less than 1 second, the cleaning object may move around in the washing tub in a messy manner, and the cleaning object may be damaged or entangled. If it is longer than 10 seconds, the number of times the cleaning target swings in the washing tub 11 in the forward direction and the reverse direction within the washing process time decreases, and the dirt removing effect due to the swing becomes small.

Next, as a condition in the intermediate dehydration step of step S11, it is set that the water in the washing tub 11 is drained and the washing tub 11 is rotated at a predetermined speed for a predetermined time (S22). At this time, it is preferable to set the rotation speed of the washing tub 11 to 200 rpm or more and 600 rpm or less. Below 200 rpm, the dehydration effect is small. If it is higher than 600 rpm, the load on the cleaning target becomes large, and the cleaning target may be damaged or entangled. The rotation speed of the washing tub 11 in the intermediate dehydration step is preferably the same as the rotation speed in the final dehydration step in step S13 or smaller than the rotation speed in the final dehydration step. If the rotation speed is higher than the rotation speed in the final dehydration step, the cleaning target may be damaged or entangled before the rinsing step or the final dehydration step, and the cleaning target may be further damaged in the rinsing step or the final dehydration step. Further, a time of 30 seconds or more and less than 3 minutes (for example, 1 minute) is set as the time for rotating the washing tub 11. The dehydration effect is small in less than 30 seconds. If the cleaning target is over 3 minutes, the cleaning target may be damaged or entangled due to a long load applied to the cleaning target.

Next, as the conditions in the rinsing step of step S12, the rinsing step time, the amount of water to be charged into the washing tub 11, and the rotation mode of the washing tub 11 are set (S23). The rinsing process time is preferably 30 seconds or more and less than 3 minutes (for example, 1 minute). If it is less than 30 seconds, the rinsing effect is small, and detergent and dirt may remain on the cleaning target. If it is 3 minutes or more, the cleaning target may be damaged or entangled due to a long load applied to the cleaning target. Further, the rinsing process time may be shorter than the washing process time. According to this, the load on the cleaning target can be reduced, and the cleaning target can be prevented from being damaged or entangled.

The amount of water in the rinsing step is preferably a medium water level (40% to 70% of the maximum water level) with respect to the maximum water level of the washing tub 11. If the water level is less than 40% of the maximum water level, detergent and dirt may remain on the cleaning target (the rinsing effect is small). If the water level is higher than 70% of the maximum water level, the degree of swelling of the cleaning target by water increases, and the degree of wrinkles and shrinkage occurring in the cleaning target may increase. The amount of water in the rinsing step may be the same as the amount of water in the washing step.

Further, as a rotation mode of the washing tub 11 in the rinsing step, it is set to repeat the operation of rotating the washing tub 11 in the forward direction for 4 hours, then stopping for 5 hours, and then rotating in the reverse direction for 6 hours. To do. At this time, it is preferable to set a speed of 25 rpm or more and 40 rpm or less as the rotation speed when rotating the washing tub 11 in the forward direction or the reverse direction. The rinsing effect may be small below 25 rpm. If it is higher than 40 rpm, the load on the cleaning target becomes large, and the cleaning target may be damaged or entangled. If three speeds (low rotation, medium rotation, and high rotation) can be set as the rotation speed in the rinsing process, it is preferable to set it to "medium rotation". The rinsing effect may be small at low rpm. At high speeds, the load on the cleaning target increases, and the cleaning target may be damaged or entangled.

Further, as the fourth time and the sixth time, for example, it is preferable to set a time of 1 second or more and 10 seconds or less. If it is less than 1 second, the degree of shaking of the cleaning target in the washing tub 11 is small, and the rinsing effect is small. If it is longer than 10 seconds, the number of times the cleaning target swings in the washing tub 11 in the forward direction and the reverse direction within the rinsing process time is reduced, and the rinsing effect is reduced.

Further, as the fifth time, for example, it is preferable to set a time of 1 second or more and 10 seconds or less. In less than 1 second, the cleaning target may move around in the washing tub 11 in a messy manner, and the cleaning target may be damaged or entangled. If it is longer than 10 seconds, the number of times the cleaning target swings in the washing tub 11 in the forward direction and the reverse direction within the rinsing process time decreases, and the rinsing effect due to the swing becomes small.

The rotation mode (rotation speed, the fourth to sixth hours) of the washing tub 11 in the rinsing step may be the same as the rotation mode (rotation speed, the first to third hours) in the washing step.

Next, as a condition in the final dehydration step of step S13, it is set that the water in the washing tub 11 is drained and the washing tub 11 is rotated at a predetermined speed for a predetermined time (S24). At this time, it is preferable to set the rotation speed of the washing tub 11 to be 400 rpm or more and 600 rpm or less. If the speed is less than 400 rpm, the dehydration effect is small, and there is a possibility that water drips from the cleaning target during drying after the final dehydration step, and the coloring of the cleaning target is removed together with the water. If it is higher than 600 rpm, the load on the cleaning target becomes large, and the cleaning target may be damaged or entangled. When three speeds (low rotation, medium rotation, and high rotation) can be set as the rotation speed in the final dehydration step, it is preferable to set it to "medium rotation". The dehydration effect may be small at low rpm. At high speeds, the load on the cleaning target increases, and the cleaning target may be damaged or entangled.

The rotation speed of the washing tub 11 in the final dehydration step is preferably the same as the rotation speed in the intermediate dehydration step or higher than the rotation speed in the intermediate dehydration step. If it is made smaller than the rotation speed in the intermediate dehydration step, the amount of water remaining in the cleaning target after the final dehydration step may increase, and in this case, it takes time to dry.

Further, it is preferable to set a time (for example, 2 minutes) of 30 seconds or more and less than 4 minutes as the time of the final dehydration step. The dehydration effect is small in less than 30 seconds. If it is 4 minutes or more, the cleaning target may be damaged or entangled due to a long load applied to the cleaning target. The time of the final dehydration step may be longer than the time of the intermediate dehydration step. According to this, the amount of water remaining in the cleaning target after the final dehydration step can be reduced.

In addition, as a final dehydration step, there is a case where a preliminary dehydration in which the rotation speed of the washing tub 11 is suppressed is performed first, and then a main dehydration in which the rotation speed is higher than the preliminary dehydration is performed. In this case, the time and rotation speed in the preliminary dehydration and the time and rotation speed in the main dehydration are set by operating the setting unit 16. At this time, the total time of the preliminary dehydration time and the main dehydration time is preferably 30 seconds or more and less than 4 minutes. Further, the main dehydration time is preferably less than 3 minutes, and the preliminary dehydration time is preferably less than 1 minute. Further, the rotation speed of this dehydration is preferably 400 rpm or more and 600 rpm or less. The rotation speed of the pre-dehydration should be smaller than the rotation speed of the main dehydration.

After the final dehydration step, the washing tub 11 may alternately rotate in the forward and reverse directions at a low speed (speed of 50 rpm or less). In this case, the conditions (time, rotation speed) set as the final dehydration step do not include the conditions for the judgment operation. That is, in the present specification, the final dehydration step and the handling operation step are treated as separate steps.

Next, the timing for switching the state of the detergent accommodating portion 13 and the charging control member 14 from the charging prohibited state to the charging permitted state is set (S25). As the timing, the time of the rinsing process in step S12 is set. Specifically, it is preferable to set the timing before the water is charged into the washing tub 11 in the rinsing step or the timing within 10 seconds after the water is charged into the washing tub 11. According to this, in the rinsing step, the quality protective agent described later can be quickly adapted to the cleaning target.

In addition, each step S21 to S25 of FIG. 7 may be carried out in any order. Further, the water temperature in the cleaning step of step S10 and the rinsing step of step S12 may be set to room temperature. Step S7 may be performed at any timing before the start of the cleaning step of step S10.

Table 1 shows the conditions set in each of steps S21 to S25 of FIG.

Returning to FIG. 1, after setting various conditions in step S7, next, the lid of the washing tub 11 is opened, and the cleaning target 1 (see FIG. 5) prepared in steps S1 to S6 is placed in the washing tub 11. Put it in (S8). At this time, a plurality of cleaning targets 1 placed in separate nets 4 may be placed in the washing tub 11, but in this case, the cleaning target 1 of a darkly colored material (for example, a black material) and the lightly colored material are lightly colored. It is preferable not to mix the material (for example, a white material) with the cleaning target 1. This is to prevent the color of the dark-colored cleaning target 1 from being transferred to the light-colored cleaning target 1.

Next, the detergent used in the washing step of step S10 and the rinsing step of step S12 is set in the washing machine 10 (S9). Specifically, for example, the detergent is set in the washing machine 10 according to the procedure shown in FIG. In FIG. 8, first, the detergent for use in the washing step of step S10 is set in the washing machine 10 (S31). Specifically, a detergent for washing with water (detergent for removing stains) and a detergent (quality protective agent) for protecting the quality (shrinkage, wrinkles, texture, color, etc.) other than the stains to be cleaned are provided in the detergent storage unit. The user directly puts it into the washing tub 11 without going through 13. At this time, the user puts the washing detergent and the quality protective agent into the washing tub 11 so as to hang it on the cloth 2 wrapping the cleaning target 1 in the washing tub 11. At the time of adding the detergent in step S31, water has not yet been added to the washing tub 11.

The washing detergent is a detergent containing a surfactant as a main component. Specifically, for example, liquid soap is put into the washing tub 11 as a washing detergent.

In addition, as a quality protective agent, specifically, Softsil (registered trademark) manufactured by NICCA CHEMICAL CO., LTD. As a first detergent having a shrink-proofing or wrinkle-proofing effect, and a second detergent having a texture-protecting effect such as tactile sensation. Nicca Chemical Co., Ltd.'s Famiton (registered trademark) DX-10 (hereinafter simply referred to as "Famiton (registered trademark)") and myoban or citric acid as a third detergent having the effect of preventing color transfer or discoloration. Is put into the washing tub 11. Softyl (registered trademark) and Famiton (registered trademark) are liquids. Alum is in powder form.

The amount of the washing detergent and each quality protective agent to be added can be appropriately determined according to the weight of the cleaning target 1 to be put into the washing tub 11 and the amount of water to be put into the washing tub 11, but Softsil (registered trademark) And Famiton® can be the same amount as each other. Specifically, the "equivalent amount" means that the input amount of one of Softyl (registered trademark) and Famiton (registered trademark) is 80% to 120% of the input amount of the other.

Next, the detergent for use in the rinsing step of step S12 is set in the washing machine 10 (S32). Specifically, the above-mentioned Softyl (registered trademark) and Famiton (registered trademark) are put into the detergent container 13 in equal amounts as quality protective agents.

The amount of soft sill (registered trademark) set in step S31 may be 80% to 120% of the amount of soft sill (registered trademark) set in step S32. The amount of Famiton (registered trademark) set in step S31 may be 80% to 120% of the amount of Famiton (registered trademark) set in step S32.

Returning to FIG. 1, the user then operates the washing start switch (not shown) of the washing machine 10 after closing the lid of the washing tub 11 to remove the dirt of the cleaning target 1 put into the washing tub 11. A cleaning step of removing is performed (S10). When the washing step is started, the control unit 17 (see FIG. 6) of the washing machine 10 puts the water level into the washing tub 11 and the rotation mode of the washing tub 11 according to the conditions preset in step S7 (conditions in Table 1). To control.

When the washing step is completed, next, intermediate dehydration is performed on the cleaning target 1 in the washing tub 11 (S11). When the intermediate dehydration step is started, the control unit 17 discharges the water from the washing tub 11 and controls the rotation mode of the washing tub 11 according to the conditions preset in step S7 (conditions in Table 1). The switching from the washing process to the intermediate dehydration process is automatically performed.

When the intermediate dehydration step is completed, next, a rinsing step of washing away the detergent and dirt remaining on the cleaning target 1 in the washing tub 11 with water is performed (S12). When the rinsing process is started, the control unit 17 switches the detergent accommodating unit 13 and the charging control member 14 from the charging prohibited state to the charging permitted state according to the conditions preset in step S7 (conditions in Table 1). The detergents (Softsil (registered trademark) and Famiton (registered trademark)) in the accommodating portion 13 are put into the washing tub 11. In addition, the control unit 17 controls the water level to be charged into the washing tub 11 and the rotation mode of the washing tub 11 according to the conditions preset in step S7 (conditions in Table 1). The switching from the intermediate dehydration step to the rinsing step is automatically performed.

When the rinsing step is completed, the final dehydration of the cleaning target 1 in the washing tub 11 is performed (S13). When the final dehydration step is started, the control unit 17 discharges the water from the washing tub 11 and controls the rotation mode of the washing tub 11 according to the conditions preset in step S7 (conditions in Table 1). The switching from the rinsing step to the final dehydration step is automatically performed.

When the final dehydration step is completed, the cleaning target 1 after dehydration is naturally dried (S14). Specifically, the user opens the lid of the washing tub 11 after the final dehydration step, and takes out the cleaning target 1 wrapped in the net 4 from the washing tub 11. After taking out from the washing tub 11, the net 4 and the cloths 2 and 3 are removed to expose the cleaning target 1. After that, the cleaning target 1 is unfolded and dried until it dries. The shrinkage of the cleaning target 1 can be suppressed by allowing it to dry naturally instead of forcibly drying it with a dryer.

After the drying step, the cleaning target 1 is ironed as necessary.

As described above, in the present embodiment, by performing the washing according to the procedure of FIG. 1, it is possible to wash with water while suppressing the quality deterioration of the cleaning target 1 formed of the natural material. Specifically, since the pretreatment for directly adhering the oxygen bleach to the cleaning target 1 is performed in step S2, the oxygen bleach is added to the washing tub 11 together with the detergent as compared with the case where the pretreatment is not performed or during the cleaning step. The bleaching agent can be sufficiently permeated into the desired portion of the cleaning target 1, and stains (dirt) can be sufficiently removed from the cleaning target 1 as compared with the case where the cleaning target 1 is charged. Further, by pretreating with an oxygen-based bleach, the time of the subsequent cleaning step can be shortened. As a result, the load on the cleaning target 1 in the cleaning process can be reduced, and quality deterioration such as damage, entanglement, shrinkage, and color transfer from the other cleaning target 1 can be suppressed.

Further, a part of the cleaning target 1 is protected by a cotton cloth 3, and the entire cleaning target 1 is wrapped with the cotton cloth 2 and the net 4, and the cleaning step, the intermediate dehydration step, the rinsing step and the final step are performed. Since the dehydration step is performed, it is possible to prevent the color from the other cleaning target 1 from being transferred to the cleaning target 1. Further, in each process, it is possible to prevent the cleaning target 1 from directly contacting the inner wall of the washing tub 11, and it is possible to prevent a plurality of cleaning targets 1 from directly contacting each other, so that the cleaning target 1 is damaged or the cleaning target 1 is damaged. It can suppress entanglement.

In general, Sofcil (registered trademark) and Famiton (registered trademark) are used in the finishing process after the rinsing process in the wet cleaning of clothes made of synthetic fibers, and these Sofcil (registered). Since the trademark) and Famiton (registered trademark) are put into the washing tub 11 in both the cleaning process and the rinsing process, it is possible to suppress the occurrence of shrinkage or wrinkles in the cleaning target 1 of the natural material, and the texture of the cleaning target 1. Can be suppressed from changing. Further, in the cleaning process, in addition to Softyl (registered trademark) and Famiton (registered trademark), alum or citric acid is also added as an inhibitor of color transfer or discoloration, so that the color transfer or discoloration of the cleaning target 1 can be further improved. It can be further suppressed.

Further, since there are only two steps of pouring water into the washing tub 11, a washing step and a rinsing step, it is possible to prevent the cleaning target 1 from swelling due to water, and by extension, prevent the cleaning target 1 from shrinking or wrinkling. it can.

Further, since the intermediate dehydration step is performed between the cleaning step and the rinsing step, the detergent and dirt remaining on the cleaning target 1 during the cleaning step can be removed to some extent before the rinsing step. As a result, the detergent and dirt remaining on the cleaning target 1 can be sufficiently removed in the subsequent rinsing step, and the time of the rinsing step can be shortened.

Cleaning was performed on each of silk garments, cotton garments, leather garments, linen garments, and wool garments according to the procedure shown in FIG. As the washing machine, a dehydration automatic washing machine WN-35S manufactured by Yamamoto Seisakusho Co., Ltd. was used. In the dehydration automatic washing machine WN-35S, the weight of the object to be cleaned that can be processed is 35 kg. The conditions for each step were the conditions shown in Table 1. More specifically, the conditions of the cleaning process are time 2 minutes, rotation speed 38 rpm (medium rotation), drum rotation time 9 seconds, drum stop time 2 seconds, and the water level is 118 L (medium water level) with respect to the maximum water level of 208 L. did. The conditions of the intermediate dehydration step were 1 minute for an hour and a rotation speed of 375 rpm. The conditions of the rinsing process were 1 minute, a rotation speed of 38 rpm (medium rotation), a drum rotation time of 9 seconds, a drum stop time of 2 seconds, and a water level of 118 L (medium water level). The conditions for the final dehydration step were a time of 2 minutes and a rotation speed of 500 rpm (medium rotation). The water temperature in the washing step and the rinsing step was set to room temperature. In the washing step, liquid soap, Sofcil (registered trademark), Famiton (registered trademark) and alum were directly put into the washing tub before adding water. At this time, the input amounts of Softyl (registered trademark) and Famiton (registered trademark) were about 200 mL each. In the rinsing process, Sofcil (registered trademark) and Famiton (registered trademark) were automatically added into the washing tub before adding water. At this time, the input amounts of Softyl (registered trademark) and Famiton (registered trademark) were about 200 mL each. In addition, each garment was pretreated with a wide highter (registered trademark) manufactured by Kao Corporation by spraying before being put into the washing tub.

As a result, stains on all the clothes were completely removed, and quality deterioration such as shrinkage, texture change, and color transfer did not occur.
