The present invention relates to a laundry dryer, and more particularly, to a structure and a method for enabling dry cleaning for a large amount of laundry using a laundry dryer.

In general, the laundry dryer is a device for drying the laundry is complete.

Figure 1 is a cross-sectional view showing the internal structure of the above-described laundry dryer, Figure 2 is a perspective view showing the appearance of the laundry dryer, with reference to this configuration of the existing laundry dryer in more detail as follows.

First, the laundry dryer includes a main body 10, a drying drum 20, a door 40, a motor 50, a heater 60, and a blowing fan 70.

In the body 10 is the inlet 11 is formed in the front, the inlet is equipped with a rim (30).

In addition, the drying drum 20 is rotatably installed in the main body, and a plurality of stirring pieces 21 protrude along the inner circumferential surface thereof.

At this time, each of the stirring pieces 21 is formed long along the longitudinal direction of the drying drum 20, so that the laundry is forcibly moved upward when the drying drum 20 is rotated so that smooth drying can be performed. .

In addition, the door 40 is rotatably mounted to an adjacent portion of the inlet 11 formed in the main body 10 to selectively open and close the inlet 11.

In addition, the motor 50 is fixed to the inner bottom of the main body 10 to generate a driving force for rotating the drying drum 20.

The heater 60 is installed inside the hot air supply passage 91 to heat air flowing through the inside of the hot air supply passage 91.

At this time, the hot air supply passage 91 serves to guide the air flow so that the outside air is introduced into the drying drum 20 and discharged to the outside of the main body 10.

In addition, the blowing fan 70 is operated to discharge dry air flowing in the drying drum 10 to the outside of the main body 10, and is provided to communicate with the hot air discharge passage 92.

Hereinafter, the clothing drying process by the laundry dryer having the above-described configuration will be described in more detail.

First, laundry to be dried is introduced into the drying drum 20.

In this way, when the laundry is added and the drying stroke is performed, the heater 60 and the motor 50 are operated.

In addition, as the blower fan 70 is operated, external air introduced into the main body through the suction side of the hot air supply passage 91 is heated to pass through the heater 60, and the hot air is heated to the hot air supply passage. It is forced into the drying drum 20 through 91.

As described above, the hot air introduced into the drying drum 20 is dried by the blowing force of the blower fan 70 to dry the wet laundry and then discharged to the outside of the main body 10 through the hot air discharge passage 92. do.

In this process, the stirring piece 21 protruding from the inner wall surface of the drying drum 20 is in contact with the laundry to prevent tangling between the laundry.

When the laundry is completely dried by repeatedly performing the above process, the door 40 is opened to discharge the laundry inside the drying drum 20.

In recent years, a study has been made to allow the laundry dryer not only to perform laundry drying but also to perform a role other than drying.

As an example, by providing a separate dry cleaning kit (kit) to enable the dry cleaning of the laundry using the laundry dryer, dry cleaning is possible at home as the dry cleaning kit.

Here, the dry cleaning kit includes a damping cloth that emits incense together with a predetermined amount of steam when it is provided with high temperature heat, a packing bag for packing a predetermined amount of laundry and the damping cloth, and decontamination of laundry by manual labor. It is configured to include a decontaminant and a fouling absorbent pad.

Therefore, the decontamination of the laundry is performed by receiving the decontamination absorbent pad at the soiled area of the laundry and then applying the decontamination agent to the debris so that the decontamination is transferred to the decontamination absorbent pad. After the laundry is embedded in the packaging bag together with the damp cloth, the cleaning bag is operated by operating the laundry dryer in a state in which the packaging bag is sealed and put into the laundry dryer.

At this time, when the hot air is provided in the drum by the operation of the laundry dryer, the moisture and the fragrance contained in the damp cloth in the bag are evaporated, thereby refreshing the laundry in the bag.

However, the above-described dry cleaning process of the conventional laundry can not be performed by the laundry dryer itself because it can be performed in the laundry dryer only when a dry cleaning kit is provided.

In particular, since the packaging bag constituting the dry cleaning kit has a very small allowable capacity, only 3 to 4 dry shirts are dry cleaned, and thus, the cost for dry cleaning compared to the purchase cost of the dry cleaning kit is limited. The reduction of has a problem that was inevitable.

In addition, among the components of the dry cleaning kit described above, many precautions are required due to the characteristics of the packaging bag.

For example, when a hole or the like is generated in the packaging bag, it is not possible to use it, and at a very high temperature, the precautions that cannot be used because the packaging bag may melt are required.

In addition, the wet cloth constituting the above-described dry cleaning kit has a problem that the contact was made only locally with the laundry because it is only put in a specific area in the bag with the laundry.

That is, even when the drying drum is rotated, the dry cleaning is performed only in the local part of the laundry (the part into which the wet cloth was first put) because the position change of the damp cloth was not made.

The present invention has been made to solve the above problems of the prior art, a dry dry cleaning for a large amount of laundry by using a laundry dryer without using a separate dry cleaning kit, and smooth dry cleaning The goal is to provide a structure that makes it possible.

In addition, the present invention has been made to solve the problems of the prior art, it is another object to provide an operating method for performing dry cleaning using a laundry dryer.

According to another aspect of the present invention, there is provided a driving method including: detecting whether a driving request for dry cleaning occurs; A second step of vaporizing the water by supplying water to a water reservoir and supplying power to a heat generating unit when a request for driving for dry cleaning occurs; A third step of spraying the vaporized steam into a drying drum and rotating the drying drum; When the dry cleaning is completed, a fourth step of discharging the steam existing in the drying drum to the outside of the drying drum is provided, and the operation method for the dry cleaning mode of the laundry dryer is provided.

Hereinafter, the present invention will be described in more detail with reference to FIGS. 3 to 7 showing preferred embodiments of the above-described embodiments of the present invention and preferred embodiments of the driving method of the present invention.

First, the laundry dryer according to the embodiment of the present invention includes a main body 110, a drying drum 120, and a steam diverging device.

Here, the main body 110 forms the appearance of the laundry dryer.

In addition, the drying drum 120 is rotatably installed in the main body 110, and is mounted such that a side opened toward the inlet 111 of the main body 110 is positioned.

At this time, the door 140 for opening and closing the inlet 111 is mounted at a portion where the inlet 111 of the main body 110 is formed, and the door 140 and the inner circumferential surface of the inlet 110. Rim 130 for sealing between the inlet 110 is mounted.

In addition, the steam dissipation device is configured to dissipate a predetermined amount of steam for dry cleaning toward the inside of the drying drum 120, at least one is provided.

In this case, the dry cleaning may be a series of processes only for refreshing laundry, but may also be a series of processes for removing various contaminants from the laundry.

The steam dissipation device is configured to include a heat generating unit 210 for providing a high temperature heat to vaporize the water.

In addition, the steam dissipation device is configured to include a steam supply pipe 220 is made of the flow of steam vaporized by the heat generating unit 210.

In addition, the steam dissipation device is configured to include a first spraying unit 230 for discharging the steam flowing through the steam supply pipe 220 into the drying drum 120.

In particular, the end of the steam discharge of the first spraying unit 230 is exposed to the inside of the drying drum 120 through the portion, for example, the rim 130, the laundry is introduced into the drying drum 120 This is more preferable.

In addition, the first spraying unit 230 may be connected to a pumping means such as a pump so that the steam flowing through the steam supply pipe 220 may be forced to be injected into the drying drum 120, as shown As described above, it is preferable to apply the structure of the valve so that steam is injected through opening and closing of the pipe line from the viewpoint of simplifying the structure and reducing the cost.

In addition, the steam dissipation device further comprises a water reservoir 240 in which a predetermined amount of water is stored to supply water to the steam supply pipe 220.

At this time, the water reservoir 240 is configured to be connected to the water supply valve 241 connected to the water pipe to enable the automatic supply of water from the outside.

Here, the heat generating unit 210 constituting the steam dissipating device may be formed as a coil heater formed to surround the steam supply pipe 220, the heat generating unit 210 as shown in the embodiment of the present invention It is also provided in the water reservoir 240 may be composed of a sheath heater (Sheath Heater) to directly vaporize the water stored in the water reservoir 240.

In this case, when the heat generating unit 210 is provided in the water reservoir 240, the water level sensor 250 may further include a water level sensor 250 for detecting the water level stored in the water reservoir 240. Do.

If the amount of water stored in the water reservoir 240 is not high enough, excessive heat generation of the heat generating unit 210 may occur, and the amount of water stored in the water reservoir 240 is excessively excessive. In many cases, the time to vaporize the water may be excessively long, so that the amount of water stored in the water reservoir 240 is always maintained at a constant level (stable enough to be vaporized). For sake.

That is, when the water level measured by the water level sensor 250 is higher than the reference value, the water supply to the water reservoir 240 is cut off, and the water level measured by the water level sensor 250 is lower than the reference value. In this case, the replenishment of water may be made into the water reservoir 240.

On the other hand, the embodiment of the present invention proposes that the detergent supply device is further provided to further improve the dry cleaning effect in the above-described laundry dryer.

Of course, there is no need for the detergent supply device, but because the efficiency is very low to dry clean the laundry only by steam only, the detergent drum is provided to provide a detergent for dry cleaning into the drying drum 120, the various kinds of laundry It is desirable to allow contaminants to be removed more smoothly.

At this time, the detergent is a solvent to which petroleum solvent is added.

In particular, the detergent is preferably added to the fragrance component to add aroma to the laundry to be dry-cleaned.

That is, the dry cleaning is to not only perform the role of refreshing the laundry, but to provide a predetermined scent so that the satisfaction with the dry cleaning can be further improved.

Here, the detergent supply device is configured to include a detergent storage container 310 is stored in the detergent for dry cleaning as shown in FIG.

At this time, the detergent reservoir 310 is provided in the main body 110, it is configured to enable the replenishment of the detergent.

In addition, the detergent supply device is configured to include a second spraying unit 320 for spraying the detergent stored in the detergent reservoir 310 into the drying drum 120.

At this time, it is preferable that the site where the discharge of the detergent which is the end of the second spraying unit 320 is made is exposed to the drying drum 120.

In particular, the end of the detergent spraying of the second spraying unit 320 is dried along with the first spraying unit 230 through a portion, for example, the rim 130, the laundry is injected into the drying drum 120 More preferably, the drum 120 is exposed to the inside.

In addition, the second spraying unit 320 may be connected to a pumping means such as a pump so that the detergent stored in the detergent storage container 310 can be forcibly sprayed toward the inside of the drying drum 120, as shown. Applying the structure of the valve so that the detergent is injected through the opening and closing of the pipe is more preferable in view of the structure can be simplified and the cost can be reduced.

However, the detergent provided through the detergent supply apparatus as described above may be configured to include only a fragrance component without containing petroleum solvent.

That is, although not shown may be provided only at least one fragrance spray device for the provision of a fragrance component, not a detergent supply device.

Of course, although not shown, both the detergent supply device and the fragrance spray device may be provided as separate configurations.

In addition, the laundry dryer according to an embodiment of the present invention is preferably provided with a contaminant transition cloth 400 for more smoothly performing dry cleaning, as shown in FIG.

At this time, the contaminant transfer cloth 400 may be transferred to the contaminants on the laundry to be dry-cleaned, so that the contaminants can be removed from the laundry, it is preferably formed of a fiber material that is easier to transfer various contaminants than the laundry. .

In particular, the contaminant transfer cloth 400 may be configured to be simply inserted into the drying drum 120 during operation for dry cleaning, but more preferably configured to be detachable inside the drying drum 120. .

That is, if the contaminant transfer cloth 400 is simply introduced into the drying drum 120, the contaminant transfer cloth 400 is entangled in the laundry during the dry cleaning process, and thus the laundry can be played only at a specific part of the laundry. In order to allow the contaminant transition cloth 400 to be contacted to more portions of the contaminant transition cloth 400, it is desirable to allow the fluid to flow separately from the laundry.

Therefore, the embodiment of the present invention suggests that the contaminant transition cloth 400 is detachably configured inside the drying drum 120.

At this time, the contaminant transfer cloth 400 may be mounted on the stirring piece 121 for smooth agitation of the laundry as shown in the embodiment, but may be configured to be mounted directly on the inner wall surface of the drying drum 120. It may be.

Hereinafter, an operation method for dry cleaning using a configuration according to an embodiment of the present invention described above will be described with reference to the flowchart of FIG. 7.

First, the controller for controlling the operation of the laundry dryer continuously checks the occurrence of the request for operation for dry cleaning (S110).

That is, when operation control of a laundry dryer by a user is generated, the controller (not shown) performs a read as to whether the operation selected by the user is for dry cleaning or for general laundry drying. This is to detect the occurrence of a request for operation for dry cleaning.

At this time, if a request for operation for dry cleaning is generated by the user, the controller requests the input of laundry to be dry cleaned.

In this case, the user closes the door 140 after putting the laundry to be dry-cleaned into the drying drum 120 and selects to perform the dry cleaning operation continuously.

In addition, it is more preferable to mount at least one contaminant transition cloth 400 on each stirring piece 121 in the drying drum 120 in the process of putting laundry by the user as described above.

Of course, after the loading of the laundry and the installation of the contaminant transfer cloth 400 are completed, the user requests a dry cleaning operation, and the controller performs control of various components for the dry cleaning operation directly by the dry cleaning request. It may be set.

Then, when the preparation for dry cleaning is completed by the above-described series of processes, the controller (not shown) rotates the drying drum (S120) and controls the detergent supply device to store the detergent stored in the detergent reservoir 310. It is provided through the second spraying unit 320 into the drying drum 120 (S130) to separate various contaminants from the laundry for dry cleaning.

At this time, the detergent may be controlled to be continuously sprayed during the dry cleaning operation, it may be made so that no further injection is made when the steam is provided into the drying drum 120.

In addition, the controller generates water by supplying water to the water reservoir 240 of the steam dissipating device and providing power to the heat generating unit 210 to vaporize the water (S140).

At this time, the water level sensor 250 provided in the water reservoir 240 and the water supply valve 241 for opening and closing the water supply pipe (that is, the water pipe) is a water level at which the amount of water stored in the water reservoir 240 is always constant. The operation is made in conjunction with the controller to maintain.

For example, when the water level sensed by the water level sensor 250 is lower than the reference water level, the water supply valve 241 is opened to supply water.

In addition, the steam generated by the above process is supplied to the drying drum 120 through the first spraying unit 230 while flowing through the steam supply pipe 220 (S150).

Therefore, the steam supplied into the drying drum 120 activates the detergent penetrated into the laundry to separate the contaminants from the laundry, thereby making the laundry refresh.

At this time, since the detergent contains a fragrance component, the fragrance component is adsorbed to the laundry to remove the smell of the laundry (including the smell of the solvent).

In addition, since the drying drum 120 is rotated by the driving of the motor 150 while the above process is being performed, since the laundry in the drying drum 120 is continuously stirred, all the laundry may be evenly refreshed. In addition, as the pollutant transfer cloth 400 flows by the rotation of the drying drum 120, the pollutant separated from the laundry is transferred.

Thus, recontamination of the laundry by contaminants separated from the laundry is prevented.

Then, if the dry cleaning is completed because the above-described series of processes are completed, the controller cuts off the water supply valve 241 and cuts off the power supplied to the heat generator 220 (S160).

In addition, the controller allows the steam existing in the drying drum 120 to be discharged to the outside of the drying drum 120 (S170) to be safe from dangers such as burns of the user by high temperature steam.

This can be performed through the rotation of the blowing fan 170.

That is, by operating the blowing fan 170 to rotate to discharge the steam in the drying drum 120 to the outside of the main body 110 through the hot air discharge passage 192.

In this process, it is preferable to control not to generate heat of the heater 160, but may heat the heater 160 to dry the dry-cleaned laundry.

If the above-described series of processes are completed and the operation of the drying drum 120 is stopped, the dry cleaning may be performed by taking out the laundry and removing and removing each contaminant transfer cloth 400 from the inside of the drying drum 120. Is done.

Of course, if you want to perform the dry cleaning of another laundry continuously, the new contaminant transfer cloth 400 is mounted in the drying drum 120, and then repeat the above-described series of processes.

As described above, the laundry dryer according to the embodiment of the present invention has an effect that dry cleaning of laundry is possible even without using a separate dry cleaning kit.

In particular, since dry cleaning is performed in all parts of the drying drum, dry cleaning for a large amount of laundry is possible.

In addition, the laundry dryer according to the embodiment of the present invention has an effect that the dry cleaning performance can be further improved because detergent and steam are uniformly provided to each laundry in the drying drum.

In particular, the detergent has an effect that can improve the user's satisfaction by containing a fragrance component.
