Description

  The present invention relates to a method for regenerating interior materials.

  The ceiling or wall of the building is decorated using interior materials. As such an interior material, an interior cloth made of vinyl chloride, cloth fabric or the like is widely used because of its excellent appearance. However, the interior cloth gradually becomes dirty due to natural deterioration or due to the generation of cigarette smoke, oily smoke, soot or mold. Therefore, when the stain becomes conspicuous, the dirty interior cloth is usually peeled off and replaced with a new interior cloth.

  However, when replacing the interior cloth in this way, it takes a long time to replace the interior cloth, or the cost is very high. Therefore, a method of regenerating an interior material in which the interior cloth is regenerated by washing has been proposed. Alternatively, there has been proposed a method of painting an interior material in which the interior cloth is painted to restore the appearance.

  Japanese Patent No. 3261499 (Patent Document 1) discloses a method of regenerating an interior material attached to a ceiling or a wall, in which a cleaning solution is sprayed on the surface of the interior material, and the cleaning solution is sprayed. There is disclosed a technique in which a physical cleaning process is performed on a surface of a material, and a water rinsing process is performed on a surface of the interior material that has been subjected to the physical cleaning process.

  Japanese Patent No. 5393720 (Patent Literature 2) discloses an interior in which a wall interior material attached to an inner wall of a building or a ceiling interior material attached to a ceiling of a building is painted to restore its appearance. As a method of coating a material, a technique of applying a water-based paint to the surface of a wall interior material or a ceiling interior material has been disclosed.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In all the drawings for describing the embodiments, the same portions are denoted by the same reference numerals in principle, and the repeated description thereof will be omitted.

(Embodiment)
Hereinafter, a method of reproducing an interior material (interior cloth) according to an embodiment of the present invention will be described. The method of regenerating interior materials according to the present embodiment is a method of regenerating interior materials that reproduces interior materials adhered to ceilings or inner walls of a plurality of rooms included in an apartment house having a plurality of dwelling units.

<How to reproduce interior materials in each room>
First, a method of reproducing the interior material in each room will be described. FIG. 1 is a flowchart illustrating an example of some steps of a method of reproducing an interior material according to an embodiment.

  In the process of regenerating the interior material shown in FIG. 1, first, the degree of contamination on the surface of the interior material is evaluated (step S1 in FIG. 1). At that time, according to the degree of contamination of the surface, for example, ranking from A evaluation to F evaluation or level 1 to level 6 is performed. The evaluation of the degree of dirt can be performed visually by a worker performing the regenerating operation. For example, the degree of dirt can be evaluated by taking a photograph of the interior surface and analyzing the photographed photograph with a computer. Good.

  Next, dust on the surface of the interior material, that is, dust attached to the surface of the interior material is removed (step S2 in FIG. 1).

  The specific method of removing dust in step S2 is not particularly limited. For example, brushing (physical cleaning) can be performed on the surface of the interior material. In addition, when dust does not adhere to the surface of the interior material, step S2 can be omitted.

  In the step of regenerating the interior material shown in FIG. 1, next, curing is performed on a region of the ceiling or the inner wall which does not require application of the cleaning treatment liquid (step S3 in FIG. 1).

  Although a specific method of applying the curing in step S3 is not particularly limited, for example, a curing tape can be attached to an outlet plate or the like. If no outlet plate or the like is provided and it is not necessary to perform curing, step S3 can be omitted.

  In the step of regenerating the interior material shown in FIG. 1, next, a cleaning treatment liquid is applied to the surface of the interior material (step S4 in FIG. 1).

The specific method of applying the cleaning treatment liquid in step S4 is not particularly limited. For example, an alkaline inorganic cleaning agent, a soil decomposing enzyme, and a first bleaching agent are dissolved in water on the surface of the interior cloth. Cleaning solution can be applied. Further, the cleaning treatment liquid can be sprayed using a low-pressure sprayer or the like, applied using a mop with a stick, or applied using a low-pressure sprayer or the like, and then applied using a mop with a stick or the like. At this time, it is preferable that the application amount of the cleaning treatment liquid, that is, the application amount is about 10 to 100 g / m ² .

  As the cleaning solution, a solution having a pH of 10 or more (alkaline) and capable of removing a wide range of dirt can be used. As described above, a cleaning solution containing an alkaline detergent, a soil decomposing enzyme, and a first bleach may be used, or an alkaline detergent, a soil degrading enzyme, and a first bleach may be used alone. May be sprayed or applied.

  Representative alkaline cleaners include, for example, those containing sodium hydroxide and sodium carbonate, sodium-based or potassium-based alkali metal salts, silicates, or aqueous cleaners containing an alkaline substance such as an ammonia compound. Can be used.

  The stain-decomposing enzyme is used to uniformly wash and finish the entire interior cloth (object to be washed). As the soil-decomposing enzyme, those containing propylene glycol, papain, polyethylene and the like can be used.

  The first bleach is used to finish the interior cloth with high brightness. The first bleach is preferably an oxidized bleach having a large effect on the alkali side. Specifically, for example, a 1 to 35% aqueous solution of hydrogen peroxide, a 1 to 20% aqueous solution of sodium peroxide, or the like is used. it can. Further, chlorine bleaching agents, for example, an aqueous solution of sodium hypochlorite having an effective chlorine of 1 to 12% are also effective.

  If the degree of dirt attached to the surface of the interior material is severe, hydrogen peroxide, those containing sodium hydroxide, etc., proteolytic enzymes, polyoxyethylene alkyl ethers, alkali metal salts such as sodium or potassium, After using an aqueous cleaning agent containing an alkaline substance such as silicate, 2-butoxyethanol, sodium metasilicate, sodium hypochlorite, etc., the water for dissolving these substances is set at 40 to 60 ° C. I do. By setting the temperature of the water for dissolving the detergent and the bleach to 40 to 60 ° C., the ability of the detergent to decompose dirt is maximized, compared with the case where the detergent is dissolved at a normal water temperature. Work efficiency is improved.

  Further, it is preferable to apply the cleaning treatment liquid thus generated to the surface of the interior material by spraying with a pressurized sprayer. By spraying the cleaning treatment liquid with a pressurized sprayer, the droplets of the cleaning liquid become fine, and the droplets of the cleaning treatment liquid that have been miniaturized can enter between the dirt components adhered to the interior material surface, As a result, the cleaning solution having the dirt-decomposing component easily penetrates deep into the dirt, and the dirt-decomposing ability is improved.

  Further, in a room where a smell such as a living smell, a pet smell or a spice is strongly attached, and / or a room where dirt is attached to the entire wall constituting the room, it is possible to spray continuously for a certain period of time. Using a possible sprayer, the cleaning treatment liquid is continuously sprayed on all walls and ceilings constituting the room. By doing so, the number of steps can be reduced and the cleaning time can be drastically shortened, while the cleaning treatment liquid is sprayed on each wall or ceiling.

  In the process of regenerating the interior material shown in FIG. 1, it is next determined whether or not the permeation time according to the degree of contamination has elapsed (step S5 in FIG. 1). (Y in the determination in step S5 in FIG. 1), the process proceeds to step S6, which is a step of performing a cleaning process. On the other hand, when the preset permeation time has not elapsed (N in the determination of step S5), step S5 is repeated until the permeation time has elapsed.

  Such a permeation time, for the dirt attached to the surface of the interior material, by performing the cleaning process after leaving for a predetermined time in a state of applying the cleaning treatment liquid, as a time such that the dirt can be reliably removed, It is set in advance. Therefore, the permeation time is set longer as the degree of contamination is larger, and the permeation time is set shorter as the degree of contamination is smaller.

  If it is determined in step S5 of FIG. 1 that the preset permeation time has elapsed, the surface of the interior material to which the cleaning liquid is applied is subjected to cleaning processing (step S6 of FIG. 1). This step S6 is a step of removing dirt on the surface of the interior material to which the cleaning treatment liquid has been applied, that is, removing dirt.

  In the cleaning process of step S6, first, a physical cleaning process is performed on the surface of the interior material (step S7 in FIG. 1).

  The specific method of performing the physical cleaning process in step S7 is not particularly limited. For example, brushing (physical cleaning) can be performed on the surface of the interior material on which the cleaning liquid is sprayed. This brushing is preferably performed after a period of about several minutes to several hours after the application of the cleaning treatment liquid. At this time, it is preferable that a cloth or the like that absorbs water is laid beforehand on the entire surface of the floor so that water does not leak under the floor.

  Alternatively, as a specific method in step S7, instead of brushing, for example, physical cleaning by wiping a cloth such as a towel or the like with a mop with a stick having a flat contact surface to wipe off dirt or detergent is performed. Is also good. In particular, in Japanese-style rooms and the like, as a material for the interior, instead of an interior cloth, a decorative board whose surface is formed of paper is often used, but in such a case, brushing is not preferable, so the contact surface is flat. It is preferable to use a mop with a stick and a towel to wipe off dirt and detergent.

  In the cleaning process of step S6, the surface of the brushed interior material is further rinsed with water (step S8 in FIG. 1). As a result, the cleaning liquid adhering to the surface of the interior cloth is removed.

  In the washing process of step S6, a stain removing liquid containing a water-soluble solvent and a second bleach is further applied (sprayed) to the surface of the interior material that has been subjected to the water rinsing process (step S9 in FIG. 1). .

  In step S9, a stain removing liquid containing a water-soluble solvent and a second bleaching agent may be used, or the water-soluble solvent and the second bleaching agent may be separately applied (sprayed).

  As a water-soluble solvent, a type of water-soluble solvent that does not damage the interior cloth, such as methyl ether, ethyl ether, butyl ether, so as to penetrate into interior cloth (particularly in the case of vinyl chloride cloth) and lift out dirt. Methylene glycol, ethylene glycol, butylene glycol and the like can be used. In the case of removing local stains, an aromatic organic solvent is effective.

  As the second bleaching agent, oxidizing bleaching agents, for example, a 1 to 35% aqueous solution of hydrogen peroxide, a 1 to 20% aqueous solution of sodium peroxide, a 1 to 12% aqueous solution of sodium hypochlorite and the like are effective. Among them, a chlorine bleach having a strong bleaching power has a good bleaching effect in a short time, and thus has good workability in terms of time. When stubborn stains are removed by static electricity, heat traces, traces, etc., it is preferable to repeatedly perform the stain removal operation with a chlorine bleach. In order to shorten the working time, it is preferable to decolorize the chlorine bleach under use conditions in which the chlorine bleach is made acidic with an inorganic or organic acidic substance. In order to avoid rapid decomposition of the chlorine bleach during operation, it is desirable to add an organic acidic substance.

  In the cleaning process of step S6, the surface of the interior material on which the stain removal liquid has been sprayed is further brushed (step S10 in FIG. 1). Then, the surface of the brushed interior material is subjected to a water rinsing process (step S11 in FIG. 1). In step S10, the surface of the interior material to which the stain removal liquid has been applied is subjected to a water rinsing process. As a result, the stain removing liquid adhering to the surface of the interior cloth is removed.

  If the surface of the interior material after performing step S10 is not completely removed of dirt and some dirt remains, step S9 and step S10 can be repeated. If the dirt has been completely removed after performing step S10, step S11 is performed to perform a water rinsing process on the surface of the interior material.

  On the other hand, when the degree of contamination on the surface of the interior material is low, only the steps S7 and S8 may be performed and the steps S9 to S11 may not be performed in the cleaning process of step S6.

  In this manner, stains on the interior cloth made of vinyl chloride, cloth, or the like can be easily removed, and the interior cloth can be regenerated so as to exhibit a good appearance. Further, since there is no need to replace the interior cloth, no waste is generated. According to such a method of reproducing the interior cloth, it is possible to completely remove stains permeated into the interior cloth. Further, the interior cloth can be washed uniformly.

  The stains on the interior cloth include oil stains, tobacco smoke stains, soot stains, mold stains, hand stains, static electricity and heat stains, furniture traces, and drinks and ink. There are many other types, including those whose cause is not clear. These stains are various, such as those that are easy to clean and those that are difficult to clean. However, according to the method for regenerating the interior material of the present embodiment, such stains can be easily removed, and the interior cloth Can be easily reproduced so as to exhibit a good appearance.

  Note that the brushing in step S7 is preferably performed before the cleaning treatment liquid applied to the surface of the interior material is dried, so that the cleaning treatment liquid and dirt can be reliably wiped off. Further, the brushing in step S8 is preferably performed before the stain removing liquid applied to the surface of the interior material is dried, whereby the stain removing liquid and dirt can be surely wiped off.

  That is, the permeation time determined in step S5 is a time during which the cleaning treatment liquid is left in a state where the cleaning treatment liquid is applied, and by allowing the cleaning treatment liquid to permeate for the predetermined time, dirt can be reliably removed. However, if the cleaning treatment liquid dries as a result of being left as it is, the time required for the cleaning treatment process increases. For this reason, it is preferable that the permeation time is set to such a time that the dirt can be surely removed and that the cleaning treatment liquid does not dry.

<Reproduction method of interior materials of multiple rooms in each dwelling unit>
Next, as a method of reproducing the interior material of the present embodiment, a method of reproducing the interior material of a plurality of rooms in each dwelling unit of an apartment house will be described. Hereinafter, a dwelling unit having a 2DK floor plan will be described as an example.

  FIG. 2 is a plan view showing an example of a dwelling unit to which the method for regenerating an interior material according to the embodiment is applied. FIG. 3 is a flowchart showing an example of the details of some steps of the method of reproducing an interior material according to the embodiment. FIG. 3 shows steps S4 to S6 among a plurality of steps included in the interior material reproducing method shown in FIG.

  In the example illustrated in FIG. 2, each dwelling unit of the apartment house has a 2DK layout including a Japanese-style room 1, a Japanese-style room 2, a dining kitchen 3, a washroom 4, and a bathroom 5, and here, among them, the Japanese-style room 1 and the Japanese-style room 2 The method of reproducing the interior materials of the two rooms will be described.

  Here, it is assumed that the degree of dirt is evaluated and ranked for all the rooms (in the present embodiment, the Japanese-style room 1 and the Japanese-style room 2) which are the targets of the method of reproducing the interior material. The degree of dirt on the surface of the interior material in the Japanese-style room 1 is higher than the degree of dirt on the surface of the interior material in the Japanese-style room 2, that is, the surface of the interior material in the Japanese-style room 1 is more dirty than the surface of the interior material in the Japanese room 2. It is assumed that

  In such a case, in step S4, as shown in FIG. 3, the cleaning treatment liquid is applied to the surface of the interior material in the order of Japanese-style room 1 (step S411) and Japanese-style room 2 (step S412). That is, in step S4, the cleaning treatment liquid is applied to the surface of the interior material in order from the room having the highest degree of contamination on the surface of the interior material among the plurality of rooms.

  Accordingly, before performing the cleaning process in step S6 in each room, the waiting time for allowing the cleaning material to permeate the interior material can be made longer in a room having a higher degree of contamination on the surface of the interior material.

  Then, in step S5, first, it is determined whether or not the permeation time according to the degree of contamination of the Japanese room 2 has elapsed for the Japanese room 2 with a low degree of contamination (step S511 in FIG. 3), and the preset permeation time has elapsed. On condition that the cleaning is performed (Y in the determination in step S511), the process proceeds to step S611, which is a step of performing the cleaning process on the Japanese-style room 2. On the other hand, if the preset permeation time has not elapsed (N in the determination of step S511), step S511 is repeated until the permeation time has elapsed.

  When it is determined in step S511 in FIG. 3 that the permeation time set in advance according to the degree of contamination of the Japanese room 2 has elapsed, the surface of the interior material coated with the cleaning treatment liquid for the Japanese room 2 is determined. Is performed (step S611).

  Subsequently, the process proceeds to step S512, where it is determined whether or not the permeation time according to the degree of contamination of the Japanese room 1 has elapsed for the Japanese room 1 (step S512), and on the condition that the preset permeation time has elapsed (step S512). In the determination of S512, Y), the process proceeds to step S612, which is a process of performing a cleaning process on the Japanese-style room 1. On the other hand, when the preset permeation time has not elapsed (N in the determination of step S512), step S512 is repeated until the permeation time has elapsed.

  Then, in step S512, when it is determined that the preset permeation time has elapsed and the step of performing the cleaning process on the Japanese-style room 1 is performed, the cleaning process ends.

  By doing so, the dirt can be reliably removed even in a room where the degree of dirt on the surface of the interior material is high, so that the interior material can be reproduced with an excellent finish over many rooms. In addition, even if the waiting time for infiltrating the cleaning solution into the interior material is set longer for a room with a higher degree of contamination on the surface of the interior material, the waiting time for the work is reduced and the cleaning process for multiple rooms is completed almost simultaneously. Thus, the interior material can be reproduced efficiently and in a short time so as to exhibit a good appearance over a large number of rooms.

  The evaluation of the degree of contamination in each room can be performed visually by a worker performing a regenerating operation.For example, a photograph of the interior surface is taken, and the photographed photograph is analyzed by a computer. The degree may be evaluated.

  In addition, in the example illustrated in FIG. 3, an example in which the cleaning treatment liquid is applied to a plurality of rooms in descending order of the degree of contamination for each of the plurality of rooms has been described. The cleaning treatment liquid may be applied in the descending order of the degree of contamination while moving back and forth between the dwelling units over a plurality of rooms.

  In step S6, as shown in FIG. 3, it is preferable to perform a cleaning process on the surface of the interior material in the order of Japanese-style room 2 (step S611) and Japanese-style room 1 (step S612). That is, in step S6, it is preferable to perform the cleaning process on the surface of the interior material in the order from the room having the lowest degree of contamination on the surface of the interior material in the plurality of rooms, that is, in the reverse order of step S4.

  Accordingly, before performing the cleaning process in step S6 in each room, the waiting time for allowing the cleaning material to permeate the interior material can be further lengthened in a room having a high degree of contamination on the surface of the interior material. Therefore, even in a room where the degree of dirt on the surface of the interior material is high, dirt can be more reliably removed, and the interior material can be reproduced with a more excellent finish over many rooms. Also, even if the waiting time for infiltrating the cleaning solution into the interior material is longer for a room with a higher degree of contamination on the surface of the interior material, the waiting time for the work is reduced and the cleaning process for a plurality of rooms is performed substantially simultaneously. The finishing can be completed, and the interior material can be efficiently reproduced in a short time efficiently over a large number of rooms.

  Note that, in the example illustrated in FIG. 3, an example has been described in which, for each dwelling unit, the cleaning process is performed in a plurality of rooms in ascending order of the degree of dirt. However, the cleaning process is performed across a plurality of dwelling units, that is, each of the plurality of dwelling units has The cleaning process may be performed in ascending order of dirt while moving between dwelling units over a plurality of rooms.

<A modification of the method of reproducing the interior materials in each room>
Next, as a first modification of the embodiment, a modification of the method of reproducing the interior material of each room will be described. Hereinafter, the Japanese-style room 1 will be described as an example of the dwelling units having the floor plan of 2DK described with reference to FIG.

  FIG. 4 is an enlarged plan view showing a room to which a method of reproducing an interior material according to a first modification of the embodiment is applied. FIG. 4 is an enlarged view of the Japanese-style room 1 which is one room of the dwelling unit shown in FIG. FIG. 5 is a flowchart showing an example of the details of some of the steps of the method for reproducing an interior material according to a first modification of the embodiment. FIG. 5 shows Step S4 of the plurality of steps of the method of reproducing the interior material shown in FIG.

  In the first modified example, in step S3, in each room, the area to which the cleaning treatment liquid is applied on the surface of the interior material attached to the plurality of inner walls is defined in the clockwise direction or the counterclockwise direction in plan view. The cleaning liquid is applied so as to make one round while sequentially moving along a preset rotation direction.

  For example, as shown in FIG. 4, the surface of the interior material 12 adhered to the inner wall 11 of the Japanese-style room 1 is rotated along a clockwise direction in a plan view into a region R1, a region R2, a region R3, a region R4, a region R5, a region R5. It is considered to be divided into R6, region R7 and region R8. In such a case, as shown in FIG. 5, for example, the region to which the cleaning treatment liquid is applied is defined as a region R1 (step S421), a region R2 (step S422), a region R3 (step S423), and a region R4 (step S424). , The region R5 (step S425), the region R6 (step S426), the region R7 (step S427), and the region R8 (step S428) are sequentially moved, and the cleaning treatment liquid is applied so as to make a round.

  When regenerating interior materials of a plurality of rooms of an apartment house having a plurality of dwelling units, since a large number of rooms are used for the work, a plurality of workers may share the work and work in a certain room. Workers may be changed on the way. In such a case, when performing the step of applying the cleaning treatment liquid in step S4, the part of the interior material adhered to the inner wall of the room to which the cleaning treatment liquid has been applied and the part to which the cleaning treatment liquid has not been applied. In some cases, it is difficult to identify the part.

  On the other hand, in the first modified example, the area to which the cleaning treatment liquid is applied on the surface of the interior material adhered to the inner wall of the room as described above is determined in advance in the clockwise direction or the counterclockwise direction in plan view. The cleaning treatment liquid is applied while sequentially moving along the set rotation direction. Thereby, even when the worker in charge of a certain room is changed on the way, of the interior material affixed to the inner wall of the room, a part to which the cleaning treatment liquid is applied and a part to which the cleaning treatment liquid is not applied Can be easily identified, so that the interior material can be reproduced efficiently and in a short time so as to present a good appearance over a large number of rooms.

  Further, it is more preferable that the cleaning treatment liquid applied to the surface of the interior material has a predetermined color (for example, white). By doing so, it is possible to more easily distinguish the portion where the cleaning treatment liquid has been applied from the portion where the cleaning treatment liquid has not been applied. The interior material can be reproduced so as to present a beautiful appearance. The color to be applied to the cleaning treatment liquid can be provided by using a coloring agent derived from artificial and / or natural components, or the color originally provided by the substance constituting the cleaning treatment liquid can be used. it can.

  Further, in the first modified example, in step S4, in each room, the area to which the cleaning treatment liquid is applied on the surface of the interior material stuck to the plurality of inner walls is set to the highest degree of contamination among the surfaces of the interior material. It is preferable to apply the cleaning treatment liquid so as to start from a high region and make a round while sequentially moving along a preset rotation direction among the clockwise rotation direction or the counterclockwise rotation direction in plan view.

  For example, in the case shown in FIG. 4, among the regions R1, R2, R3, R4, R5, R6, R7, and R8, the region R3 has the highest degree of contamination among the surfaces of the interior material 12. Consider the case of an area. In such a case, for example, the region to which the cleaning treatment liquid is applied goes around while sequentially moving in the order of the region R3, the region R4, the region R5, the region R6, the region R7, the region R8, the region R1, and the region R2. Apply the cleaning solution.

  In such a case, since the cleaning treatment liquid can be first applied to the area of the surface of the interior material having the highest degree of contamination, the interior material is subjected to the cleaning process before performing the cleaning process in step S6 in each room. The waiting time for infiltrating the liquid can be made the longest in the area of the surface of the interior material where the degree of contamination is highest. Therefore, even in the area of the surface of the interior material where the degree of dirt is the highest, dirt can be more reliably removed, so that an excellent finish can be obtained that exhibits a better aesthetic appearance. In step S4, the method of applying the cleaning treatment liquid while sequentially moving along the preset rotation method starting from the area with the highest degree of contamination is performed only in one of the plurality of rooms. Can also.

  In the first modification, in each room, a region to which the cleaning treatment liquid is applied on the surface of the interior material attached to the plurality of inner walls is determined in advance in a clockwise direction or a counterclockwise direction in a plan view. It is preferable to apply the cleaning treatment liquid to the surface of the interior material that is finally attached to the ceiling after applying the cleaning treatment liquid while sequentially moving the cleaning treatment liquid along the set rotation direction. By setting such an order, even when the worker is changed on the way, the part of the interior material affixed to the inner wall or ceiling of the room to which the cleaning treatment liquid is applied and the part to which the cleaning treatment liquid is applied are applied. Since it is possible to more easily identify a part that is not present, it is possible to reproduce the interior material more efficiently and in a shorter time so as to exhibit a good appearance over a large number of rooms.

<Method of recycling interior materials across multiple dwelling units>
Next, as a second modified example of the embodiment, a method of regenerating interior materials over a plurality of dwelling units in an apartment house will be described. In the following, a description will be given of an example of an apartment house having a total of six dwelling units by having two dwelling units on each floor of a three-story building.

  FIG. 6 is a diagram showing a table in which the degree of dirt on the surface of the interior material in each dwelling unit provided in the apartment house to which the method of reproducing the interior material of the second modification of the embodiment is applied is classified into six levels. . In FIG. 6, for example, the dwelling unit 101 is simply described as 101. FIG. 7 is a flowchart illustrating an example of the details of some of the steps of the method of reproducing an interior material according to the second modification of the embodiment. FIG. 7 shows steps S4 to S6 of a plurality of steps included in the interior material reproducing method shown in FIG.

  In the second modification, it is assumed that the apartment house has a dwelling unit 101 and a dwelling unit 102 on the first floor, a dwelling unit 201 and a dwelling unit 202 on the second floor, and a dwelling unit 301 and a dwelling unit 302 on the third floor.

  In addition, as shown in FIG. 6, it is assumed that the degree of contamination of the surface of the interior material in a plurality of rooms of each dwelling unit is classified into six levels from level 1 to level 6 in advance. It is assumed that the degree of contamination increases in the order of level 1, level 2, level 3, level 4, level 5, and level 6. That is, it is assumed that level 1 has the lowest degree of contamination and is the least dirty, and level 6 has the highest degree of contamination and the most dirty. It is also assumed that such a degree of contamination has been evaluated in advance in step S1 shown in FIG. The evaluation of the degree of dirt can be performed visually by a worker who performs the regenerating operation. For example, the degree of dirt can be evaluated by taking a photograph of the interior surface and analyzing the photographed photograph with a computer. Good.

  The degree of contamination of the surface of the interior material in a plurality of rooms of each dwelling unit may be a value evaluated and compared under the same conditions. For example, the degree of contamination of the surface of the interior material in each of a plurality of rooms of each dwelling unit is acceptable. Or the maximum value of the degree of contamination of the surface of the interior material in each of the plurality of rooms in each dwelling unit.

  Here, as shown in FIG. 6, the degree of dirt in the dwelling unit 101 is level 1, the degree of dirt in the dwelling unit 102 is level 6, the degree of dirt in the dwelling unit 201 is level 3, and the degree of dirt in the dwelling unit 202 is level. 4, the degree of dirt in the dwelling unit 301 is at level 5, and the degree of dirt in the dwelling unit 302 is at level 2.

  In such a case, in step S4, as shown in FIG. 7, the dwelling unit 102 (step S431), the dwelling unit 301 (step S432), the dwelling unit 202 (step S433), the dwelling unit 201 (step S434), and the dwelling unit 302 (step S435). Then, the cleaning treatment liquid is applied to the surface of the interior material in the order of the dwelling unit 101 (step S436). That is, in step S4, the cleaning treatment liquid is applied to the surface of the interior material in order from a dwelling unit having a high degree of contamination on the surface of the interior material among the plurality of dwellings.

  Thereby, before performing the cleaning process in step S6 in each dwelling unit, the waiting time for allowing the cleaning treatment liquid to permeate the interior material can be made longer for a dwelling unit having a higher degree of contamination on the surface of the interior material. Therefore, even in a dwelling unit having a high degree of dirt on the surface of the interior material, the dirt can be reliably removed, so that the interior material can be regenerated with an excellent finish over a large number of dwelling units. In addition, even if the waiting time for infiltrating the cleaning solution into the interior material is set longer for a dwelling unit having a higher degree of contamination on the surface of the interior material, the cleaning process for a plurality of dwelling units can be completed at substantially the same time. , The interior material can be reproduced efficiently and in a short time so as to give a good appearance.

  Then, in step S5, first, it is determined whether the penetration time according to the degree of contamination of the dwelling unit 101 has elapsed for the dwelling unit 101 with the lowest degree of contamination (step S531 in FIG. 7), and the preset permeation time is determined. On condition that the time has elapsed (Y in the determination of step S531), the process proceeds to step S621, which is a process of performing a cleaning process on the dwelling unit 101. On the other hand, if the preset permeation time has not elapsed (N in the determination of step S531), step S531 is repeated until the permeation time has elapsed.

  If it is determined in step S531 in FIG. 7 that the permeation time set in advance according to the degree of contamination of the dwelling unit 101 has elapsed, the surface of the interior material to which the cleaning treatment liquid has been applied is applied to the dwelling unit 101. Is performed (step S621).

  Subsequently, the process proceeds to step S532, where it is determined whether or not the penetration time according to the degree of contamination of the dwelling unit 302 has elapsed for the dwelling unit 302 having the second lowest degree of contamination next to the dwelling unit 101 (step S532). (YES in step S532), the process proceeds to step S622, which is a step of performing a cleaning process on the dwelling unit 302. On the other hand, if the preset permeation time has not elapsed (N in the determination of step S532), step S532 is repeated until the permeation time has elapsed.

  Then, such a determination of the passage of the permeation time and the cleaning process are performed for all the dwelling units in the order of the lowest degree of contamination, and the step of performing the cleaning process on the dwelling unit 102 with the highest degree of contamination is performed. The cleaning process ends.

  In this way, even in a dwelling unit where the degree of dirt on the surface of the interior material is high, dirt can be reliably removed. Therefore, even in a dwelling unit having a high degree of dirt on the surface of the interior material, the dirt can be reliably removed, so that the interior material can be regenerated with an excellent finish over a large number of dwelling units. Also, even if the waiting time for infiltrating the cleaning material into the interior material is longer for dwelling units with a higher degree of contamination on the surface of the interior material, the waiting time for work can be reduced and the cleaning process for multiple dwelling units can be completed almost simultaneously. Thus, the interior material can be efficiently reproduced over a large number of dwelling units so as to exhibit a good appearance in a short time with good efficiency.

  In step S6, as shown in FIG. 7, the dwelling unit 101 (step S621), the dwelling unit 302 (step S622), the dwelling unit 201 (step S623), the dwelling unit 202 (step S624), the dwelling unit 301 (step S625), and the dwelling unit 102 It is preferable to perform a cleaning process on the surface of the interior material in the order of (Step S626). That is, in step S6, it is preferable to perform the cleaning process on the surface of the interior material in order from a dwelling unit in which the degree of dirt on the surface of the interior material among the plurality of dwellings is low, that is, in the reverse order of step S4.

  Thereby, before performing the cleaning process in step S6 in each dwelling unit, the waiting time for infiltrating the cleaning material into the interior material can be further lengthened for a dwelling unit having a higher degree of contamination on the surface of the interior material. Therefore, even in a dwelling unit having a high degree of dirt on the surface of the interior material, the dirt can be more reliably removed, so that the interior material can be regenerated with a more excellent finish over a large number of dwelling units. Also, even if the waiting time for infiltrating the cleaning solution into the interior material is longer for dwelling units having a higher degree of contamination on the surface of the interior material, the waiting time for work can be reduced and the cleaning process for a plurality of dwelling units can be performed substantially simultaneously. The finishing can be completed, and the interior material can be efficiently reproduced over a large number of dwelling units so as to exhibit a good appearance in a short time.

  As described with reference to FIGS. 2 and 3 described above, in step S4, for each dwelling unit, a cleaning process is performed on the surface of the interior material in descending order of the degree of contamination on the surface of the interior material among the plurality of rooms. A liquid may be applied. Thereby, in each dwelling unit, it is possible to efficiently regenerate the interior material so as to exhibit a good appearance in a short time.

  Further, as described with reference to FIGS. 2 and 3 described above, in step S6, for each dwelling unit, a cleaning process is performed on the surface of the interior material in the order of the degree of contamination on the surface of the interior material among the plurality of rooms. May be applied. Thereby, in each dwelling unit, the interior material can be reproduced more efficiently and in a short time so as to exhibit a good aesthetic appearance.

<Other modifications of the method of reproducing the interior materials in each room>
Next, as a third modification of the embodiment, another modification of the method of reproducing the interior material in each room will be described. FIG. 8 is a flowchart illustrating an example of some steps of a method of reproducing an interior material according to a third modification of the embodiment.

  In the third modified example, after performing the cleaning process in step S6, the surface of the interior material subjected to the cleaning process is coated (step S12 in FIG. 8).

  In step S12, for example, a water-based paint of a color such as white (white) or ivory is applied. Such a method is called makeup or touch-up.

  As the water-based paint, a water-based paint including a flex emulsion paint can be used. The flex emulsion paint is a synthetic resin emulsion paint (for example, acrylic) that has improved adhesion to interior materials such as interior cloth (for example, vinyl cloth), wallpaper, gypsum board, and Gyptone (registered trademark). Even if it is applied very thinly on the surface of the interior material, the coating film does not form a broken portion on the surface of the interior material.

  When the surface of the interior material is strongly stained, the stain may not be easily removed from a part of the surface of the interior material even if the cleaning process in step S6 is performed.

  On the other hand, in the third modified example, after performing the cleaning process in step S6, step S12 is performed. As a result, even if the dirt cannot be removed from a part of the surface of the interior material even after the cleaning process in step S6, the surface of the interior material is painted by applying the coating on the surface where the dirt remains. To give an excellent finish so that the interior material has a better appearance.

  In step S12, when the surface of the interior material is to be painted in the area where the dirt remains, it is preferable to repeat painting and drying alternately and to apply the paint several times. This makes it possible to gradually bring the color of the area where the stain remains to the color of the area where the stain does not remain, so that the interior material can be reproduced so as to exhibit a good appearance.

  Further, in step S12, a paint mixed with a repair agent may be applied. Penet (registered trademark) or the like can be used as a repair agent. Thereby, even if there is a flaw or the like in a part of the surface of the interior material, by coating the surface of the interior material in the area where the flaw or the like is present, the flaw is made less noticeable by making the flaw inconspicuous. An excellent finish can be obtained so as to exhibit an aesthetic appearance.

  In the third modification, after performing step S11, the interior material is removed to expose the inner wall in a part of the inner wall on which the surface of the interior material has been cleaned (step S13 in FIG. 8). Then, a repair material for repairing the interior material may be attached to the exposed inner wall (step S14 in FIG. 8). Such a method is called patchwork. FIG. 8 illustrates an example in which steps S13 and S14 are performed after performing step S12. However, after performing step S6, steps S13 and S14 are performed before performing step S12. Is also good.

  In some areas of the inner wall, the interior material may be in a broken state such as being peeled off. In such a case, by performing steps S13 and S14 of FIG. 8, even if the interior material is lost in a part of the inner wall, the interior wall is covered with a larger area than the area where the interior material is lost. Since a repair material can be newly attached in place of the material, an excellent finish can be obtained so as to exhibit a better aesthetic appearance.

  As described above, the invention made by the inventor has been specifically described based on the embodiment. However, the present invention is not limited to the embodiment, and various modifications can be made without departing from the gist of the invention. Needless to say.

  Further, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described above. For example, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of one embodiment can be added to the configuration of another embodiment. . In addition, a part of the configuration of each embodiment may be added, deleted, or replaced with another configuration.
