Description

Specification

[Technical field] Commercial washing method and commercial washing machine used therefor

The present invention relates to a commercial laundry method and a laundry machine used therefor, and more particularly to a commercial laundry method and a laundry machine for performing laundry in a washing tub using water and detergent.

[Background technology]

Generally, so-called dry cleaning is the mainstream as a washing method for business use. In such dry cleaning, washing is performed using a solution for dry cleaning, and the stains on the laundry are removed by a chemical action. Such dry cleaning has the convenience of completing the washing and drying steps in a short time. However, the dry cleaning solvents used there, such as CFC-113, 1, 1, 1, and trichloroethane, have been discontinued because they are ozone-depleting substances and are currently in mainstream use. Perchlorethylene, which is a solvent that has been used, is feared for contamination of groundwater and carcinogenicity.

In particular, in Japan, many dry cleaning systems use petroleum-based solvents, which have caused air pollution problems because of their high volatility. As described above, the washing method based on the chemical action of the solvent has the advantages that the washing is completed in a short time and the shrinkage of the laundry is small, but there is a concern about the above-mentioned adverse effects on the human body and nature. ing.

Therefore, it has been proposed to carry out laundry for business use mainly with water without using the above-mentioned chemical solvents as much as possible. However, in the case of washing mainly with water, it is necessary to sufficiently operate mechanical force, that is, to operate the washing tub and move the laundry inside, in order to reliably remove dirt. It is necessary to properly adjust the washing time and the temperature of the washing liquid. In the past technology (Japanese Unexamined Patent Publication No. 59-14444487), in a washing drum of a rotary drum type, washing is performed by mixing bubbles generated by a bubble generator into the washing liquid. Techniques are disclosed.

[Problems to be solved by the invention] In the conventional commercial washing method described above, washing mainly using water requires a washing operation using a certain amount of mechanical force, and the washing process and the like are more difficult than when a dry cleaning solvent is used. The required time will be long. Therefore, there is a problem that the laundry tends to contract or be damaged. Also, in the above-mentioned Japanese Patent Application Laid-Open No. 59-14487, the idea of washing by mixing air bubbles is disclosed. No specific technology for solving the above problem is disclosed.

The present invention has been made in order to solve the above-mentioned problems, and the purpose is to provide a business that can effectively prevent shrinkage and damage of laundry when performing commercial laundry mainly using water. It is an object of the present invention to provide a washing method for washing and a washing device used therefor.

[Disclosure of the Invention]

In order to achieve the above object, the commercial laundry method according to claim 1,

Air bubbles are introduced from underneath the laundry put in the washing tub, and the operation of the washing tub is controlled so as to be basically stationary.

With such a configuration, washing using water and detergent by the action of air bubbles has become more effective. That is, the air bubbles cause the washing water to flow by the upward movement, and also pass along or through the laundry from below, thereby making the washing action by the water and the detergent effective.

In the present invention, the operation of the washing tub, that is, the operation for moving the laundry put therein is reduced. That is, the operation of the washing tub is controlled so that the operation is basically performed in a stationary state, and the operation time is an operation for changing the position of the laundry, and this operation removes the dirt on the laundry. That is not the case.

Therefore, the fibers on the surface of the laundry do not become fluffy even though it is basically washed with water, and it is possible to effectively prevent the laundry from shrinking (shrinking) in the drying process after the washing. The shrinkage (shrinkage) of the laundry is mainly due to the fact that the fibers on the surface of the laundry become fuzzy and shrink during drying due to entanglement. According to the above-mentioned method, such fluffing can be effectively prevented by the effective use of air bubbles and the operation control of the washing tub, even though the washing is performed with water. It is a desirable commercial washing method that does not have any adverse effects due to the Leeung solvent.

In addition, it is preferable that the size of the bubble is basically fine, but the diameter can be adjusted as described later. In the commercial laundry method according to claim 2,

The size of the bubbles introduced into the washing tub is appropriately adjusted according to the type of the laundry. The fiber density of laundry varies depending on the type of laundry. Therefore, by adjusting the size of the bubbles to be used in accordance with the laundry, the passage of the bubbles in the laundry is further enhanced in the washing effect.

In the commercial laundry method according to claims 3 and 4,

The operation of the washing tub is an intermittent operation in which the operation of the washing tub is operated for a predetermined time every predetermined time, so that the ratio of the operation time to the stationary time is 10% or less. For example, it is operated every 20 seconds in less than 2 seconds. Thereby, the laundry can be washed while the laundry is moved at regular intervals of a predetermined time while the laundry is almost stationary, and the contraction of the laundry after the washing is completed can be effectively prevented.

In the commercial washing method according to claims 5, 6, 7, and 8, the drainage performed during the washing process is performed when the washing tub is not operating. In other words, by preventing the laundry from moving as much as possible during drainage, the fibers on the surface of the laundry are effectively prevented from fluffing.

The commercial laundry device according to claim 9 is:

A pump for supplying water for washing, a pipe arranged to introduce ice supplied from the pump from the lower part of the washing tank into the tank, and a pipe provided in the middle of the pipe. An air bubble generator for mixing air bubbles into the washing water; and a washing tub operation control unit for controlling the operation of the washing tub so that a ratio of an operation time to a static time is 10 <«or less. Have.

This makes it possible to achieve the business-use washing method described in the above claim, and it is possible to perform washing while effectively preventing shrinkage of the laundry while washing with water.

The commercial laundry device according to claim 10 is It has a bubble generator that can adjust the size of bubbles to be generated. Thereby, it is possible to select an appropriate bubble size according to the density of the fibers of the laundry, and it is possible to further enhance the cleaning effect.

[Best Mode for Carrying Out the Invention]

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a schematic configuration of a commercial washing machine for carrying out a method according to an embodiment of the present invention.

In the present embodiment, a drum-type washing tub 10 is used as a washing tub. The drum-type washing tub 10 includes a drum outer shell 10a and a drum inner shell 10b, and has a motor as a drive unit for performing a rotation direction operation as shown by an arrow 100 in the figure. 11, has a belt 13 attached to its rotating shaft, and the belt 13 is attached to a pulley 115 on the drum side.

The operation control of the drum-type washing tub 10 is performed by control signals from the control unit 12, and the operation control is performed by the operation panel 14 so that the device user can adjust the operation control. I have to.

A characteristic of the present embodiment is that water for rinsing is supplied from a lower position of the drum type washing tub 10. The washing water supply / discharge unit 16 is formed so as to be fed into the tub. What is more characteristic is that fine water bubbles are mixed in the supplied washing water 102. In the present embodiment, an air bubble generator 18 is provided, in which air bubbles are mixed and then supplied into the drum washing tub 10. In the present embodiment, this water is supplied by forming a circulation path, and the pump 20, the bubble generator 18, and the washing water supply / discharge section 16 of the drum are connected by a pipeline. It forms a circulation path. In addition, a button trap 24 is provided in front of the pump 20 so as to be able to capture lost items from the laundry. The discharge channel for discharging water is separately formed (reference numeral 22).

In the present embodiment, the control unit 12 also controls the operation of the pump 20 and the bubble generator 18 in accordance with an instruction from the control panel 14.

Further, a feature of the present embodiment is the operation control of the drum type washing tub 10, The control unit 12 can control at least the ratio of the operation time to the rest time to be 10% or less. For example, the drum type washing tub 10 is controlled to rotate for 2 seconds every 20 seconds. At this time, various patterns of the rotation operation can be selected. For example, it is also possible to perform a rotation operation every 10 seconds.

The water used for this washing is passed through a water softener, etc., and is used with a hardness of 3 ppm or less. As a result, washing can be performed efficiently with as little detergent as possible.

Further, the bubble generator 18 generates bubbles of, for example, 15 microns or less and supplies them. In other words, such fine air bubbles are sent into the drum type washing tub 10 in a state where they are mixed in the water sent from the pump 20. The pump used is a pump capable of obtaining a flow rate of 100 liters per minute at a total head of 50 m, and the detergent is mixed with 0.015% of the total water volume. As for the method of mixing the detergent, it is sufficient to adopt the same one as in a general commercial laundry system.

Next, a specific configuration example of the present washing apparatus and a specific washing operation will be described. Figure 2 shows an example of actual piping. As shown in the figure, a drum inner drum 10b that is driven to rotate is provided in the drum outer drum 10a of the drum type washing tub 10 and a lower position of the drum outer drum 10a is provided. A washing water supply / drain section 16 for supplying / draining washing water is formed, and a pipe 30 drawn from the front side of the washing water supply / drain section 16 passes through a pot trap 24. And a line 32 is provided from the pump 20 to the bubble generator 18. Further, the bubble generator 18 is connected to the washing water supply / discharge unit 16 by a line 34. I have.

In addition, the configuration of the supply portion of the washing water into the drum type washing tub 10 is such that air bubbles rise from a wide range as much as possible at a portion corresponding to the bottom of the power drum outer shell 10a (not shown). It is preferred that the introduction of washing water containing bubbles does not impede the cleaning action of such bubbles.

FIG. 3 shows a state where the laundry 200 is actually put inside and an actual washing operation is being performed. As shown, from the large area at the top of the It is understood that the washing water containing air bubbles is introduced. The fine bubbles 40 mixed in the washing water rise upward, but at this time, along the laundry in the tub, Or go up through the laundry. Therefore, the washing action with the washing water can be improved while the laundry is kept stationary without operating the drum inner shell 10b. Therefore, basically, washing using fine bubbles is performed without performing the washing operation by moving the laundry 200 by rotating the drum.

Then, in order to occasionally move the stationary position of the laundry 200, as shown in FIG. / Perform the operation to rotate only for the time. By this operation, the laundry is switched up and down and left and right positions are switched. This makes it possible to achieve uniform washing by the flow of washing water containing fine bubbles. As described above, in the present embodiment, the rotating operation of the inner drum 10b is not intended for the movement of the laundry to remove the dirt from the laundry, but for the position movement of the laundry in a stationary state. It is used only to make

The washing operation according to the present embodiment is characterized in that the rotation of the drum is performed only for the limited time as described above, but the drum is always stopped when the washing water in the drum is drained. I have to do that.

According to the above-described embodiment, the harmful effects of washing with washing water mainly composed of water, that is, the fibers on the surface of the washing become fluffy when immersed in water, The harmful effect that the fiber is entangled with the fiber of the other part by being moved and dried as it is, which causes a large shrinkage, is eliminated. That is, although the laundry is immersed in the water, the laundry is not moved for washing, so that the above-described shrinkage due to the entanglement of the fibers can be effectively prevented.

As for the washing function, washing water containing air bubbles is introduced from a lower position of the drum, that is, a lower position of the laundry put in, and flows upward by the action of the air bubbles. As a result, the washing water passes through the stationary laundry. Therefore, good cleaning efficiency is also ensured.

Note that the present invention is not limited to the configuration of the above embodiment, and the gist of the invention Various modifications are possible within the range. For example, as for the operation time of the drum washing tub, the ratio of the operation time to the stationary time can be set to various ratios if the operation is based on a stationary state that can prevent the fluffing of the laundry. In particular, it is possible to set various ratios within a preferable range of 10% or less. In addition, the size of the bubbles generated by the bubble generator 18 can also be adjusted in various ways depending on the material of the laundry and the like, and it is possible to perform washing by appropriately mixing bubbles.

[The invention's effect]

As described above, according to the present invention, by performing the washing with the washing water mainly composed of water, it is possible to avoid various problems such as the case where the washing is performed using the solvent for dry cleaning. In addition, it is possible to effectively prevent the shrinkage (shrinkage) of the laundry, which is a harmful effect when washing with water, and to carry out this operation. And maintain the health of workers.
