Description

  The present invention relates to a laundry cleaning apparatus and a method for efficiently washing a non-photocatalytic diluent having a deodorizing effect or tourmaline into the laundry.

Titanium oxide (TiO ₂ ), which is a photocatalyst, is known to produce active oxygen having high reactivity from water and oxygen in the air when exposed to sunlight, and is effective in sterilization and malodor decomposition. It can adsorb and decompose bad odors such as ammonia, acetaldehyde and hydrogen sulfide. Titanium oxide is used by adhering to particles of silica (SiO ₂ ), for example. On the other hand, titanium oxide requires sunlight ultraviolet rays but does not require light, and a non-photocatalyst that reacts with oxygen in the air is also known. For example, there is a titanium phosphate compound. If sprayed or applied to laundry, etc., the effect of sterilization and deodorization can be maintained even in the case of long-term chase. (See Patent Document 1)

  When spraying or applying a non-photocatalyst dissolved in water to laundry, it is difficult to spray the entire surface of a shirt, for example, by manual spraying. The same applies when using a spray gun. It is even more difficult to apply with a brush.

  In the method in which the non-photocatalyst is added to the rotating drum filled with water at a predetermined concentration in the washing rinsing process, the non-photocatalyst diluent is likely to be wasted. The method of making a non-photocatalyst diluted solution in a bag and immersing the laundry has a problem in that a lot of non-photocatalyst adheres to the laundry soaked first, and the concentration of the laundry soaked later decreases.

Tourmaline is a stone that always has electric properties and is popular as a jewelry for jewelry, but since the early 1990s, various uses have been discovered and developed as environmental and health improvement materials, and it has come to the spotlight. .
Tourmaline is a hexagonal stone with a hardness of 7 to 7.5 and a specific gravity of 3 to 3.3, and is a brown (magnesium) called drabite, black (iron) called shawl tourmaline, and lithia tourmaline of opaque stone. White, pink and red ones are called tourmaline ores that are not worthy of gemstones, and have come to be used as environmental improvement materials and industrial materials.

As one of the environmental improvement effects of tourmaline, the deodorizing effect has recently attracted attention and has come to be used in various fields.
Since the handling of tourmaline has many similarities to the non-photocatalyst, only the differences from the non-photocatalyst will be described below.
JP 2002-308712 A

  An object of the present invention is to provide a laundry cleaning apparatus and method for efficiently spraying a non-photocatalytic diluent having a deodorizing effect or tourmaline onto a laundry.

  A laundry cleaning apparatus according to the present invention stores an inverter motor capable of forward / reverse rotation and rotational speed control, a rotating drum connected to the inverter motor and loaded with laundry, a non-photocatalytic diluent or tourmaline. A low-speed rotation having a centrifugal force smaller than the weight of the laundry, a tank for injecting the non-photocatalyst diluent or tourmaline, and an air compressor for sending the non-photocatalyst diluent or tourmaline to the nozzle. Alternatively, the present invention is characterized in that the required amount of the non-photocatalyst diluent or tourmaline is sprayed on the laundry while applying the low-speed rotation with inversion at regular intervals to the rotating drum.

  It is preferable that the nozzle is provided at an opening end of an outer cylinder in which the rotating drum is accommodated, or inside a door.

  The nozzle preferably includes a plurality of nozzle holes having different diameters.

  The laundry cleaning method according to the present invention is the laundry cleaning device according to claim 1, wherein the laundry requires glueing and deodorizing, or a non-photocatalytic diluent or a mixed solution obtained by mixing laundry with a tourmaline. Is used.

  The laundry cleaning method according to the present invention is the laundry cleaning apparatus according to claim 1, wherein when the laundry requires a soft finish and deodorization, a non-photocatalytic diluent or tourmaline is mixed with a softener. A liquid is used.

  The laundry cleaning apparatus according to the present invention includes an inverter motor capable of forward / reverse rotation and rotational speed control, a rotating drum connected to the inverter motor and loaded with the laundry, and a container storing tourmaline ore. And a washing water circulation device that circulates the washing water in the container and is activated when the water comes into contact with the tourmaline ore, and is washed with the activated washing water. .

  According to the laundry cleaning apparatus of the first aspect, since a mechanism for spraying the non-photocatalytic diluent or tourmaline onto the laundry is incorporated, an efficient cleaning finishing process can be performed. Since an appropriate amount of non-photocatalytic diluent or tourmaline is sprayed on each laundry, there is no waste. In addition, rotation with centrifugal force smaller than the weight of the laundry, especially in the case of a horizontal rotating drum, causes the laundry to be lifted and dropped, so spray non-catalytic diluent or tourmaline evenly over the laundry. Can do. Since the laundry rolls even if the rotating drum is reversed at regular intervals, the same effect can be obtained. Further, the non-photocatalytic diluent or tourmaline can be quickly soaked into the laundry by the rotation of the rotating drum.

Laundry impregnated with a non-photocatalyst or tourmaline has an insect-repellent action that keeps ticks away, a deodorizing action that eliminates odors such as sweat, and an antifouling action that makes pollen and the like difficult to attach. It is also harmless. Use of non-photocatalyst or tourmaline has the following effects. For example, in dry cleaning for business use, a petroleum solvent called sol is generally used. The sol is collected by evaporating with hot air in the drying process of dry cleaning, but it may remain on clothes and give off a specific odor. Since the non-photocatalyst or tourmaline completely eliminates this smell, the finished quality of the laundry can be improved.
The effect of the laundry cleaning method of claim 6 is the same as that of claim 1.

  According to the nozzle of the second aspect, since the nozzle is provided at the opening end of the outer body or the inside of the door, the non-photocatalytic diluent or tourmaline can be directly sprayed on the laundry. Adhesion efficiency is better than when sprayed in the form of mist from the mesh-like side surface of the rotating drum.

  Since the nozzle of claim 3 has a plurality of nozzle holes with different diameters, in the case of a horizontal rotary drum, the shower that comes out of the nozzle hole with a small diameter goes to the back of the rotary drum and the nozzle hole with a large diameter. The shower that came out of can be skipped nearby.

  According to the laundry cleaning method of claim 4, since a non-photocatalyst diluent or a mixed solution of tourmaline mixed with laundry paste is used, if the laundry requires gluing and deodorization, finishing can be done in one step. it can.

  According to the laundry cleaning method of claim 5, since a non-photocatalyst diluent or a mixed solution obtained by mixing a tourmaline with a softening agent is used, if the laundry requires softening and deodorizing, it is finished in one step. Can do.

A non-photocatalyst is a new catalyst that does not require any light or other energy like a titania phosphate compound, and continues to exhibit the action of decomposing, antibacterial, and deodorizing air pollutants.
Tourmaline is also called tourmaline and has properties such as the production of negative ions and the emission of far infrared rays, which are useful for health and the environment.
The tourmaline changes the water content to ions with a surface-active action called negative hydroxyl ions, so that a cleaning effect, a deodorizing effect, and a sterilizing effect can be obtained.

  In the present invention, tourmaline is used in the form of a solution or dispersion by diluting a fine powder of about 5 to 50 μm with water as in the case of the non-photocatalyst, but the tourmaline ore having a particle diameter of 1 mmφ or more is brought into contact with water. Can be activated and used.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. A cleaning device is a household washing machine equipped with a vertical or oblique rotating drum and capable of washing and dewatering, a laundry dewatering machine installed in a coin laundry, etc. and equipped with a horizontal rotating drum, and commercial dry cleaning. Any of a solvent recovery dryer provided with a rotating drum used in the above, a steam dryer provided with a rotating drum, and the like may be used.

  FIG. 1 is a structural diagram of the cleaning device. The cleaning device 100 is a washing and dewatering device in which a horizontal rotary drum 1 is mounted inside an outer cylinder 2. The rotating drum 1 is also referred to as an inner cylinder and has, for example, a cylindrical shape having a diameter of 900 mm and a depth of 600 mm. The rotating drum 1 is rotated by a motor 3, and the motor 3 is configured to receive power supply from an inverter 4. The rotation speed of the rotary drum 1 can be designated and changed from the control panel 16 by the inverter 4. Further, forward and reverse rotation of the rotary drum 1 is also possible. The opening 17 of the outer drum 2 is provided with an edge so as to cover the rotary drum 1. When the door 9 is closed during washing, the door 9 and the outer drum 2 make the rotary drum 1 sealed. Further, the side surface of the rotating drum 1 has a mesh structure, and rotates so that the laundry 20 is immersed in the washing water 25 collected at the bottom of the outer drum 2.

In the tank 5, a non-photocatalytic diluent or tourmaline 14 is stored. The non-photocatalyst diluent or tourmaline 14 is introduced into the tank 5 from the liquid supply port 18 in advance. The capacity of the tank 5 is 20 liters. This capacity is not limited to this. For example, the amount of the non-photocatalyst diluted solution or tourmaline 14 used is about 6 liters, and may be adjusted accordingly. The tank 5 has a gauge for displaying the remaining amount of the non-photocatalytic diluent or tourmaline 14. The tank 5 may be provided with a pressure gauge. An air compressor 6 was connected to the tank 5 as a pump for sending the non-catalytic catalyst diluent or tourmaline 14 to the nozzle 8 side. A pump or the like may be attached in the middle of the flexible pipe 7 regardless of the air compressor 6.
Either a non-photocatalyst or tourmaline may be added, or tourmaline fine powder and a non-photocatalyst may be added simultaneously.

  The nozzle 8 is provided at the upper end of the opening 17 of the outer drum 2 so that the rotating drum 1 is placed horizontally and the non-photocatalyst diluent or tourmaline 14 reaches the inner part of the rotating drum 1. In FIG. 1, it is provided directly above the opening. However, the present invention is not limited to this, and the rotating drum 1 may be shifted in the rotating direction. The nozzle 8 may be provided inside the door 9. Thereby, the non-photocatalyst diluent or tourmaline 14 can be directly sprayed on the laundry 20. The non-photocatalytic diluent or tourmaline 14 injected from the nozzle 8 can be injected so as to reach the depth of 600 mm of the rotating drum 1. The depth is not limited to 600 mm, but there is also a depth reaching 1000 mm. Therefore, it is preferable to make the shower 26 like rain because spraying in the mist does not reach the back. If the water droplets are large, the distance can be increased. The mist generally has a particle size of 20 to 30 microns and cannot float in the air. If it is a shower like rain, the particle size is as large as 500 to 1000 microns, and the flight distance can be obtained. In addition, since the non-photocatalytic diluent or tourmaline 14 is not injected from the side surface of the outer drum 2, it is not necessary to form a mist to pass through the mesh on the side surface of the rotating drum 1.

  FIG. 2 is a side view of the nozzle. The nozzle 8 has a mounting portion 13 to the flexible pipe 7, and a plurality of nozzle holes of a small hole 10, a medium hole 11, and a large hole 12 are arranged from the top at a semi-cylindrical tip portion. The non-photocatalyst diluted solution or tourmaline 14 enters from the right side of the drawing, becomes a shower 26 from the left side, is sprayed into the rotating drum, and sprayed on the laundry 20.

  FIG. 3 is a front view of the nozzle. The nozzle 8 is provided with a small hole 10, a medium hole 11, and a large hole 12. Since the small hole 10 has a flying distance, the laundry 20 on the back side of the rotary drum 1 can be showered. The large hole 12 showers the laundry 20 on the near side of the rotary drum 1. Such a situation occurs in a horizontal rotary drum and does not occur in a vertical rotary drum. Therefore, in the vertical rotating drum, all the nozzle holes may be small holes to reduce the discharge pressure.

FIG. 4 is provided with a container 30 containing tourmaline ore instead of the tank 5 of the cleaning device of FIG.
Water used for washing is passed through a container 30 containing tourmaline ore to activate the water, and pumped to the rotary drum 1. The washing water 25 collected at the bottom of the rotary drum 1 is returned to the container 30 through a pipe and is brought into contact with the tourmaline ore again for regeneration.

  The step of spraying the non-catalytic catalyst diluent or tourmaline 14 on the laundry 20 is preferably after the steps of washing, rinsing and dehydration are completed. In this case, the rotating drum 1 is rotated at a low speed, not at a high speed such as 600 rpm during dehydration. The rotational speed varies depending on the type of laundry 20 (its weight), but is set to a speed at which the rotating drum 1 rotates and the laundry 20 is lifted, and then falls by its own weight while reaching the top. It is preferred that That is, the centrifugal force caused by the rotation is made smaller than the weight of the laundry. Thereby, since the laundry rolls, the non-photocatalytic diluent or tourmaline 14 can be sprayed evenly over the laundry. In the case of a vertical rotating drum, it is preferable to reverse the direction of rotation to change the direction of the laundry. Also, since the glue or softening agent can be mixed with the non-photocatalytic diluent or tourmaline, both can be performed simultaneously in this step. The glue is used on shirts, white robes, sheets, yukatas, tablecloths, etc. Use softeners such as towels and towels. Light dehydration is performed at the end of this step.

Next, in order to confirm the deodorizing effect of the laundry impregnated with the non-photocatalyst, deodorizing tests 1 to 3 using ammonia were performed. In any test, a good deodorizing effect is observed. First, in Test 1, 80 shores were washed with a detergent in a water washing machine and passed through a step of spraying a non-photocatalyst diluent after the dehydration step. The non-photocatalytic diluent is a mixture of a titanium phosphate compound stock solution of 15 cc and pure water of 900 cc and a softening agent of 3 cc. Anionic softener α was used as the softener. One Oshibori has a total area of 0.25 m ² . Therefore, the total area of 80 Oshibori is 20 m ² . Four pieces of ammonia were sprayed with 2 cc of ammonia, sealed in a bag, and the residual concentration of odor was measured with a gas-tech detector tube every hour. The results of Test 1 are shown in Table 1.

In the test 2, 17 shirts were washed with a detergent in a water washing machine and passed through a step of spraying a non-photocatalyst diluent after the dehydration step. The non-photocatalyst diluent is a mixture of 900 cc pure water and 3 cc paste with 15 cc of a titanium phosphate compound stock solution. The starch used was starch, which is natural starch. The surface area of the front and back of one shirt is about 1.2 m ² , and the area of 17 shirts is 20 m ² . Two shirts were sprayed with 2 cc of ammonia, sealed in a bag, and the residual concentration of odor was measured with a gas-tech detector tube every hour. The results of Test 2 are shown in Table 2.

Test 3 is a test in which 17 shirts dry-cleaned with a petroleum-based solvent were sprayed with a non-photocatalytic diluent in a drying process using a solvent recovery dryer. The non-photocatalyst diluent is a mixture of 15 cc of a titanium phosphate compound stock solution and 600 cc of pure water and 2 cc of glue. The concentration was slightly increased. The starch used was starch, which is natural starch. The surface area of the combined front and back sides of a sheet of shirts with 1.176m ^2, the area of 17 sheets is 20 m ^2. Two shirts were sprayed with 2 cc of ammonia, sealed in a bag, and the residual concentration of odor was measured with a gas-tech detector tube every hour. The results of Test 3 are shown in Table 3.

In case of washing 130 shirts at a time with a commercial laundry dehydrator, it is 156 m ² . Since using the non-photocatalytic dilution of approximately 1 liter with 20 mm ^2, no photocatalyst dilutions in this case is approximately 8 liters is necessary. In order to perform this in an injection time of about 5 minutes, a nozzle discharge amount of 1.6 liters / minute (= 8 liters / 5 minutes) may be prepared.
