WASHING MACHINE, MIST STATE WATER SUPPLYING DEVICE AND WASHING MACHINE PROVIDED WITH THE SAME, AND DRYING MACHINE}

The present invention relates to a washing machine. Moreover, this invention relates generally to the apparatus for supplying the water of fog state, and the washing machine provided with the same, Specifically, It is provided with the fog state water supply apparatus which supplies water in the fog state by ultrasonic wave, And it is provided with it Is about a washing machine. The invention also relates to a dryer.

Background Art Conventionally, there is a washing machine that supplies water in a mist state (mist) to a laundry in order to increase the absorbency of the clothes or to sufficiently dissolve the detergent by spraying the laundry on clothes such as clothes by reducing the particle size of water.

For example, JP 2001-276472 A and JP 2002-18187 A disclose a washing machine that performs mist water after main water is supplied to a level lower than the set water level in the water supply stroke. By the mist water supply in such a water supply stroke, a laundry becomes familiar with water, and the detergent adhered to the surface of a laundry also melt | dissolves. In addition, in this washing machine, mist water is intermittently performed in the washing process, and when the laundry floats, the water is knocked from the upper side by the mist water to prevent the washing of the laundry.

In Japanese Laid-Open Patent Publication No. 2005-73836, in order to apply water to every corner of a laundry and to make it familiar with water and detergent quickly, in the first step of a water supply stroke, the water is sprinkled with mist from above from the laundry. A washing machine for slowly rotating a washing and dewatering tank by a peristaltic rotation is described.

Japanese Patent Laid-Open No. 2006-25901 and Japanese Patent Laid-Open No. 2006-51324 disclose a washing machine that supplies normal water supply and hot water mist (hot water in a fog state).

In addition, there is conventionally an apparatus for ultrasonically vibrating a horn (piezoelectric element) to spray a liquid such as water or a chemical liquid.

For example, International Publication No. 00/66277 pamphlet describes a liquid spray device in which ultrasonic vibration of a horn (piezoelectric element) is started when a chemical liquid is supplied from an ampoule into a spray chamber, and the chemical liquid is sprayed from the top of the horn. have. In this liquid spray device, when the chemical liquid is sprayed at the upper part of the horn, the chemical liquid is ejected from the ampoule to the spray chamber through the feed pipe through the force.

In addition, there is conventionally a dryer that supplies water (mist) in a mist state to the laundry in order to prevent overdrying when the laundry wet with water is dried in a dryer. By doing in this way, overdrying is suppressed, the fixation of a wrinkle is suppressed, and a touch is improved, and the finishing state of clothing is improved. In addition, clothing is prevented from being rubbed in a dry state, thereby suppressing the generation of static electricity.

For example, in the laundry dryer of Unexamined-Japanese-Patent No. 2003-299898, in the drying process, the water misted by the spray nozzle is sprayed in an inner tank, and it is made to dry, adding moisture to clothing.

However, in the conventional washing machine, since mist is generated by passing water through a small hole like a shower, a hole through which water passes may be clogged by detergents or garbage.

In addition, in order to generate mist by passing water through a small hole, a certain amount of water pressure is required. However, depending on the environment where the washing machine is installed, sufficient water pressure may not be obtained in order to stably generate mist.

In addition, since the size of the mist particle size is determined by the size of the hole through which water passes and the water pressure, the particle size of the mist cannot be adjusted as necessary.

In addition, the mist generated by such a method is strong in straightness, and may end only by wetting a specific part of the laundry.

Accordingly, an object of the present invention is to provide a washing machine capable of generating water in a stable fog state without being influenced by the environment in which the washing machine is installed.

In a conventional washing machine, in a water supply stroke or a washing stroke, a predetermined amount of water is supplied directly from the tap water without a fog state among all the amount of water supplied to the laundry until the set water level is reached. Is supplied in a fog state. Therefore, the time when the water in a mist state is supplied is time until water reaches the set water level at the maximum. In this way, in the washing machine which does not supply the water in the mist state after the water reaches the set water level, when some of the laundry floats in the water even if the water is supplied to the set water level, the whole laundry may not be sufficiently wetted. In addition, a detergent may remain on the surface of the laundry which floated in water. If the whole laundry is not wet enough or a detergent does not melt, the laundry may not be washable enough.

Accordingly, another object of the present invention is to provide a washing machine capable of sufficiently absorbing an object to increase cleaning power.

In the liquid spraying device described in the pamphlet of International Publication No. 00/66277, the chemical liquid for spraying is supplied from the ampoule into the spray chamber through the supply pipe so that the chemical liquid for spraying directly comes into contact with the horn. In this way, when the chemical liquid directly touches the horn, the chemical liquid forms a film on the surface of the horn and cannot be sprayed stably.

Accordingly, another object of the present invention is to provide a mist state water supply device capable of generating stable mist state water, and a washing machine having the same.

In addition, in the laundry dryer disclosed in Japanese Patent Laid-Open No. 2003-299898, water is made to be fogged by a spray nozzle, so that a predetermined water pressure is required to make the water to be fogged. Depending on the environment in which the laundry dryer is installed, sufficient water pressure may not be obtained in order to stably generate misty water. In addition, since the amount of water in the mist state sprayed in the inner tank is determined by the water pressure, it is difficult to adjust the amount of water sprayed in the inner tank, and the humidity in the inner tank cannot be adjusted.

In addition, since the water misted by the spray nozzle has high straightness, only a specific part of the laundry may be wetted. In this way, it is difficult to impart proper moisture to the entire laundry in the inner tank.

Accordingly, another object of the present invention is to provide a dryer which is capable of generating water in a stable fog state without affecting the environment in which the dryer is installed, and can impart proper moisture to the object.

In addition, in the conventional washing machine, since the washing and dehydrating tank is rotated slowly by the interlocking rotation while sprinkling the water of the mist state on the laundry, the whole laundry overlapping each other cannot be sufficiently wetted with the water of the mist state, and the water of the mist state is Even if sprayed, the cleaning power may not be sufficiently increased.

Accordingly, another object of the present invention is to provide a washing machine capable of increasing the cleaning power.

A washing machine according to one aspect of the present invention includes a container for accommodating an object, and a mist water supply device for supplying water into a container in a state of fog by ultrasonic waves.

In the case of making water into a fog state by ultrasonic waves, by adjusting the frequency of the ultrasonic waves, the amount of water in the fog state, the particle size of the water in the fog state, and the timing of generating the water in the fog state can be adjusted. Since the water pressure is not necessary to set the water in the fog state, the water can be in the fog state regardless of the environment in which the washing machine is installed. Since it is not necessary to increase the water pressure, it is circulated by a small pump or the like, so that water in a fog state can be generated even by using a circulating water that is difficult to increase the water pressure.

In addition, in order to make the water misty, it is not necessary to pass the water through a small hole, so even if the wash water contains solids or deposits such as fibers, garbage, or detergent, the hole is clogged to generate misty water. There is no possibility of making it impossible, and it can generate | occur | produce mist state stably. Therefore, for example, in the washing machine which circulates the water in a storage tank, even if circulating water containing a detergent etc. is used, water of a mist state can be generated stably. In addition, even when water, such as the remaining water in a bathroom, or waste water such as hair, is used, water in a stable state can be generated.

In addition, since the water misted by the ultrasonic wave has low linearity, when the object is supplied into the container in which the object is housed, the entire object can be wetted without wetting only a specific portion of the object.

By doing in this way, the washing machine which can generate | occur | produce the water of stable fog state can be provided, regardless of the environment where a washing machine is installed.

In the washing machine according to one aspect of the present invention, it is preferable that the mist state water supply device supplies water into the storage tank in a mist state in a washing stroke for washing at least an object with water and a detergent.

By doing in this way, the whole object becomes easy to become familiar with water and a detergent, and washing power can be improved. In addition, by making the water containing the detergent into a mist state by ultrasonic waves, it is possible to dissolve the detergent in water well by the emulsification action. By supplying the water which melt | dissolved the detergent well in the container, the washing power of the water used for washing can be improved. In addition, since there is little detergent remaining after melting, it is possible to ensure a good rinsing performance stably, hardly cause contamination by mold or bacteria in the storage tank, and clean inside the storage tank.

In the washing machine according to one aspect of the present invention, it is preferable that the mist state water supply device supplies the water in the mist state in the rinsing stroke in which the object to be cleaned in the washing stroke is rinsed with water.

In a rinsing stroke, the mist state water supply apparatus mists water which does not contain a detergent or does not contain much detergent. By doing in this way, the mist state water supply apparatus itself can be wash | cleaned.

In addition, by supplying misty water into the storage tank in the rinsing stroke, the detergent attached to the object or the storage tank can be dropped well.

According to another aspect of the present invention, a washing machine includes: a receiving tank for accommodating an object, a circulation channel for distributing water discharged from the receiving tank and returning it to the receiving tank, and storing the water for distributing the circulation channel in a fog state. And a fog water supply device for supplying the tank.

The water supply device has a circulation channel for returning water discharged from the inside of the tank containing the object to the tank, and the mist state water supply device makes the water circulating through the circulation channel into the mist state, after the water has been collected to the set level in the tank. Even in this case, the water can be circulated to supply fog water into the storage tank. By supplying water circulating through the circulation channel into the storage tank in a fog state, water in an arbitrary time and fog state can be supplied into the storage tank without increasing the water more than the set water level.

Thus, since the water in the fog state can be supplied into the storage tank regardless of the set water level or the water supply time, the object floating in the water when the water reaches the set water level can also be wetted with the water in the fog state.

By doing in this way, the washing machine which can fully absorb an object and raises a washing power can be provided.

In the washing machine according to still another aspect of the present invention, it is preferable that the mist state water supply device has a spray port for discharging the water in the mist state, and the spray port is open toward the inside of the storage tank.

Since the spray opening is directly opened in the receiving tank, the fog water generated by the mist water supply apparatus is combined with each other to increase the size of the mist, and reduce the waste caused by attaching to the wall surface of the water channel, thereby preventing mist of an appropriate particle size. It can be supplied to the object without leaving anything behind.

In the washing machine according to still another aspect of the present invention, it is preferable that the mist state water supply device supplies the water in a mist state in the washing tank at least in a washing stroke in which the object is washed with water and a detergent.

By doing in this way, the whole object becomes easy to become familiar with water and a detergent, and washing power can be improved. In addition, by making the water containing the detergent into a mist state by ultrasonic waves, it is possible to dissolve the detergent in water well by the emulsification action. In addition, since the particles of water are small in the water of the mist state, the permeability to the object is good, and the washing power of the water used for washing can be improved by supplying the water in which the detergent was melt | dissolved in the container.

In the washing machine according to still another aspect of the present invention, it is preferable that the mist state water supply device supplies the water in the mist state in the rinsing stroke to rinse the object washed with the water in the washing stroke.

In a rinsing stroke, the mist state water supply apparatus mists water which does not contain a detergent or does not contain much detergent. By doing in this way, the mist state water supply apparatus itself can be wash | cleaned.

In addition, by supplying misty water into the storage tank in the rinsing cycle, the particles of the water can be made small to improve the permeability, and the detergent attached to the object or the storage tank can be dropped well.

According to another aspect of the present invention, there is provided a mist water supply apparatus, including a conduit for distributing water, a supply passage for supplying water into the conduit along the tangential direction of the inner circumferential surface of the conduit, and disposed inside the conduit, It is provided with a mist for making the water mist state.

By supplying water into the conduit from the supply passage along the tangential direction of the inner circumferential surface of the conduit, it becomes difficult for the water to directly reach the misting portion disposed in the conduit. Since water hardly touches the mist, the water film covering the surface of the mist is difficult to form.

By doing in this way, the fog state water supply apparatus which can generate | occur | produce the water of stable fog state can be provided.

In the fog state water supply device which concerns on another aspect of this invention, the mist part has the edge part formed in plate shape, the edge part has the end surface of the long side, and the end surface of the short side, It is preferable that the mist part is arrange | positioned in a pipeline so that a surface may extend along the direction of water gathering in a pipeline.

Water in the fog state is generated at the end of the fog unit formed in a plate shape. Since the end surface of the mist part is arrange | positioned so that the end surface of the short side may extend along the direction where water gathers in a pipeline, the mist part sucks up a predetermined amount of water by the pumping effect, and mists it.

For example, when the misting section is arranged so that the end face on the short side of the end of the misting section extends along the horizontal plane, the amount of mist generated is greatly changed by the amount of water collected in the pipeline.

Therefore, the mist part has an end formed in plate shape, and the mist part is arrange | positioned in the pipeline so that the end surface of the short side of the edge part may extend along the direction of water gathering in a pipeline, and the quantity of the water in a pipeline changes. Even in this case, the water in the mist state can be stably generated.

It is preferable that the fog state water supply apparatus which concerns on another aspect of this invention is provided with the protrusion which protrudes toward the inside of a pipeline from the inner peripheral surface of a pipeline.

By doing in this way, it is supplied in a pipeline along the tangential direction of the inner peripheral surface of a pipeline, collides with water which flows along the inner peripheral surface of a pipeline, and weakens the force, and can prevent that water level becomes too high. In addition, when there is momentum in the water flow, the water is prevented from coming directly from the inner circumferential surface of the pipe and directly contacting the misting part, and the water level is too high to prevent the oscillation of the ultrasonic wave from becoming abnormal and the water from being fogged. can do.

A washing machine according to another aspect of the present invention includes a container for accommodating an object, and any one of the above-mentioned mist state water supply apparatuses, and the mist state water supply apparatus supplies the mist state water into the vessel. Do.

By doing in this way, the washing machine which can generate | occur | produce the water of stable fog state can be provided, regardless of the environment where a washing machine is installed.

According to still another aspect of the present invention, a dryer includes a water tank for accommodating an object, a water supply flow path through which water is supplied to supply water into the water tank, and water in the water supply flow path through the ultrasonic wave in a mist state. And a mist water supply device for supplying.

In the case where the water is in the fog state by the ultrasonic waves, the amount of water in the fog state, the particle size of the water in the fog state, and the timing of generating the water in the fog state can be adjusted by adjusting the water supply or the frequency of the ultrasonic waves. Since the water pressure is not necessary to make the water in the fog state, the water can be in the fog state regardless of the environment in which the dryer is installed.

Moreover, since the water which became the fog state by the ultrasonic wave has low linearity, when supplying in the accommodation tank in which the object is accommodated, it can raise the humidity in a storage tank, without wetting only a specific part of the object.

In addition, by making the flowing water in the water supply flow path into the fog state, water containing no bacteria or the like can be supplied into the water tank in the fog state.

By doing in this way, it is possible to provide the dryer which can generate | occur | produce the water of a stable mist state without being influenced by the environment in which a dryer is installed, and can give a suitable moisture to a target object.

In the dryer according to another aspect of the present invention, the mist-like water supply device has a discharge port for discharging the water in the mist state and the non-mist state, so that the water in the non-fog state is discharged from the discharge port to the outside of the receiving tank It is preferable to have an induction member for inducing water in a state.

By doing in this way, since the water in the non-fog state is guided to the guide member and does not flow into the inside of the receiving tank, and only the water in the mist state is supplied into the holding tank, the humidity in the holding tank can be increased without wetting the object to be dried.

It is preferable that the dryer which concerns on another aspect of this invention is equipped with the hot air blower outlet for blowing a hot air in a storage tank, and the fog state water supply apparatus is arrange | positioned in the position spaced apart from a hot air blower outlet.

In the mist state water supply apparatus which makes water mist by ultrasonic waves, temperature characteristics may change at high temperature, and stable operation may not be possible.

Therefore, the mist state water supply apparatus can be made difficult to raise the temperature of the mist state water supply apparatus by arrange | positioning in the position spaced apart from the hot air blower which blows warm air.

A washing machine according to still another aspect of the present invention rotates around a water tank, a rotation axis extending in a horizontal direction, or a rotation axis inclined with respect to the horizontal direction in a water tank, thereby washing, rinsing, and dewatering an object therein. And a mist water supply device for supplying the water into the reservoir in a mist state.

The water tank is rotated around the rotation axis extending in the horizontal direction or the rotation axis inclined with respect to the horizontal direction in the water tank, so that even if the objects overlap with each other, the fog state supplied from the mist water supply apparatus into the water tank is maintained. Water becomes easy to wet the whole object. In addition, when detergent is supplied in a storage tank, detergent and water permeate an object quickly and uniformly.

By doing in this way, the washing machine which can raise cleaning power can be provided.

As described above, according to the present invention, it is possible to provide a washing machine capable of generating water in a stable fog state without being influenced by the environment in which the washing machine is installed.

The above and other objects, features and advantages of the present invention will become more apparent in light of the following detailed description of the preferred embodiments described in conjunction with the accompanying drawings.

The water supplied to the bubble elimination water supply hose 452 flows into the cooling duct 330 through the cooling duct 330, and dissipates bubbles generated by stirring of the detergent component in the cooling duct 330. The water supplied from the jet nozzle 450 to the rotary drum 120 directly through the shower outlet hole of the packing cover 115 (FIG. 2) passes through the small hole 121 of the rotary drum 120. Flows in.

When the circulation pump 460 is driven, the water in the water tank 130 is returned from the internal drain hose 430 to the flow dividing nozzle 450 through the circulation hose 440. In addition, the water in the water tank 130 is drained from the internal drain hose 430 to the outside of the laundry dryer 1 through the external drain hose 431 when the drain valve 432 (FIG. 2) is opened.

The water returned to the dividing nozzle 450 through the circulation hose 440 is supplied into the wet mist water supply hose 451, the bubble erasing water supply hose 452, and the rotating drum 120. When the ultrasonic unit 200 is driven, the water supplied to the wet mist water supply hose 451 becomes a fog state by the ultrasonic unit 200, and is supplied into the rotating drum 120, and the It flows into the water tank 130 through the small hole 121. The water supplied to the bubble elimination water supply hose 452 flows into the cooling duct 330, dissipates bubbles generated by stirring of the detergent component in the cooling duct 330, and is disposed at the lower portion of the cooling duct 330. Flows into the tank 130. Water supplied into the rotary drum 120 directly from the jet nozzle 450 through the shower outlet hole of the packing cover 115 flows into the water tank 130 through the small hole 121 of the rotary drum 120.

Thus, the water in the washing dryer 1 passes through the inside of the washing dryer 1 through the rotating drum 120, the water tank 130, the internal drain hose 430, the circulation hose 440, and the dividing nozzle 450. Circulate Thus, the water circulating inside the laundry dryer 1 is called circulating water. The rotary drum 120, the water tank 130, the internal drain hose 430, the circulation hose 440, and the dividing nozzle 450 are an example of a circulation channel.

The path | route made is an example of a water supply path | route. The ultrasonic unit 200 supplies the water supplied from the water supply unit 410 and the water supplied from the water jet nozzle 450 into the rotary drum 120 in a fog state.

As described above, the water supplied to the ultrasonic unit 200 through the dry mist water supply hose 411 is only tap water supplied from the tap water, not circulating water circulating in the laundry dryer 1. On the other hand, the water supplied to the ultrasonic unit 200 through the wet mist water supply hose 451 is a tap water supplied from the water supply unit 410 to the wet mist water supply hose 451 through the flow nozzle (450), It may be the circulation water supplied from the circulation hose 440 to the wet mist feed water hose 451 through the dividing nozzle 450. Through the wet mist water supply hose 451, whether or not to supply the circulating water to the ultrasonic unit 200, and to supply the tap water or the circulating water, in the washing or drying operation of the laundry dryer 1, Thus selected.

As shown in FIG. 6, the ultrasonic unit 200 and the warm air blowing port 311 of the air supply duct 310 are disposed above the rotary drum 120 in the upper portion of the water tank 130. Below the spray port 250 of the ultrasonic unit 200, the guide feather 116 is arrange | positioned as a guide member in the frame of the packing cover 115 (FIG. 2). The guide feather 116 is outside the opening of the rotating drum 120 and is located inside the inner circumferential surface of the water tank 130. In addition, the guide feather 116 may be formed as part of the shape of the packing cover 115.

From the warm air blower outlet 311 of the air supply duct 310, hot air is supplied into the rotating drum 120 as shown by arrow R1 of a double-dotted line. From the spray port 250 of the ultrasonic unit 200, as shown by the broken line M, the misty water is supplied into the rotating drum 120. FIG. In addition, from the spray port 250 of the ultrasonic unit 200, the water of the non-fog state which is not in the fog state falls down as indicated by the arrow W. FIG. The water in the rain fog flows into the water tank 130 by being separated between the outer circumferential surface of the rotating drum 120 and the inner circumferential surface of the water tank 130 by the guide feather 116.

In the rotary drum 120, the air in the air supply duct 310 blows out from the front side of the laundry dryer 1 through the hot air blowing port 311. The warm air blowing port 311 is disposed on the right side of the rotary drum 120 as viewed from the front side of the laundry dryer 1. On the other hand, the ultrasonic unit 200 is arranged on the left side of the rotary drum 120 as viewed from the front side of the laundry dryer 1. In this way, the warm air jetting ports 311 and the ultrasonic unit 200 are spaced apart from each other at intervals.

As shown to FIG. 7A and FIG. 8A, the ultrasonic wave unit 200 is equipped with the nozzle 201 and the case 202. As shown in FIG. The nozzle 201 is comprised from the conduit line 220, the water supply path 230 for wet mist, and the water supply path 240 for dry mist. The water mist supply path 230 for wet mist is connected with the wet mist water supply hose 451 (FIG. 6), and the water supply passage 240 for dry mist is connected with the dry mist water supply hose 411 (FIG. 6). . The inside of the pipe line 220, the inside of the wet mist water supply path 230, and the inside of the dry mist water supply path 240 communicate with each other. The spray port 250 is opened in the conduit 220 as a discharge port. The ultrasonic unit 200 is disposed in the laundry dryer 1 (FIG. 6) such that the spray port 250 is inclined downward from the horizontal plane. The spray port 250 is directed into the rotary drum 120 of the laundry dryer 1.

As shown in FIGS. 7B and 8B, the inside of the ultrasonic unit 200 includes a horn 210 as a fog unit and a vibrator for ultrasonically vibrating the horn 210 as one end of the horn 210. 213 is disposed. In the horn 210, the edge part 211 on the opposite side to the side to which the vibrator 213 is adhere | attached is formed in plate shape. The horn 210 is disposed in the nozzle 201 such that the end 211 of the horn 210 is located at the spray port 250 of the nozzle 201. The edge part 211 of the horn 210 is comprised from the end surface 212 of the short side, and the end surface 216 of the long side. The electrode 215 and the rear striking plate 214 are connected to the vibrator 213.

When a voltage is applied to the vibrator 213 through the two electrodes 215, the vibrator 213 vibrates ultrasonically. When the vibrator 213 vibrates ultrasonically, vibration is transmitted to the horn 210 adhered to the vibrator 213, and the end portion 211 of the horn 210 vibrates at the frequency of the ultrasonic wave in which the vibrator 213 vibrates. .

As shown in FIG. 9, the spray hole 250 of the ultrasonic unit 200 has the end surface of the short side of the edge part 211 (FIG. 7B, 8B) of the horn 210 (FIG. 7B, 8B). (Front end surface) 212 is disposed. The end surface 212 extends substantially in the vertical direction, and a predetermined interval (about 1 mm in this embodiment) is opened from the inner circumferential wall surface of the pipe line 220 in the vertical direction. In the conduit 220, the rib 222 protrudes from the inner circumferential wall surface of the conduit 220 toward a direction perpendicular to the direction in which the end surface 212 extends, that is, a substantially horizontal direction.

As shown in FIG. 10, in the water mist supply path 230 for wet mist, water flowing into the water mist supply path 230 for wet mist from the upper portion of the water mist supply path 230 for the wet mist is in the conduit 220. When flowing in, it is formed in the nozzle 201 so that it may flow in the tangential direction of the inner peripheral surface 221 along the inner peripheral surface 221 of the pipeline 220. Similarly to the water mist supply path 230 for the wet mist, the water supply passage 240 for the dry mist flows into the dry mist water supply passage 240 from the upper side of the dry mist water supply passage 240. When it flows into 220, it is formed in the nozzle 201 so that it may flow in the tangential direction of the inner peripheral surface 221 along the inner peripheral surface 221 of the pipeline 220. As shown in FIG.

Referring to FIGS. 7A to 10, a process in which the ultrasonic unit 200 is sprayed from the spray port 250 by misting water by ultrasonic waves will be described.

Water flowing in from the upper side into the wet mist water supply passage 230 flows downward from the wet mist water supply passage 230 into the duct line 220 in the tangential direction of the inner circumferential surface 221 of the pipeline 220. do. Water flowing into the pipe line 220 flows along the inner circumferential surface 221 in the pipe line 220 toward the bottom of the pipe line 220 in the counterclockwise direction as viewed from the direction of the spray port 250. If the force of the water flowing into the conduit 220 is strong, the water flows upward along the inner circumferential surface 221 through excessively the lowermost part of the conduit 220, but if it flows up to the position of the rib 222, it fits the rib 222. When it touches, the force weakens and falls downward clockwise from the spray port 250.

On the other hand, the water which flowed in from the upper in the water supply path 240 for dry mist is downward in the tangential direction of the inner peripheral surface 221 of the pipe line 220 from the dry mist water supply path 240 to the pipe line 220. Flows into. The water flowing into the conduit 220 from the water supply path 240 for the dry mist is clockwise along the inner circumferential surface 221 and the rib 222 of the conduit 220 in a clockwise direction. It flows toward the bottom of the conduit 220. The water flowing into the conduit 220 is not circulating water, but is tap water supplied from the tap water, and the amount of water is controlled by controlling the water supply valve for dry mist (FIG. 3) so that the force is not too strong.

As such, water flowing into the conduit 220 from the water mist supply path 230 for the wet mist and the water supply path 240 for the dry mist flows along the inner circumferential surface 221 of the conduit 220, so that the conduit 220 It is difficult to reach the side of the horn 210 which is arranged in the).

In the lowermost part of the conduit 220, the water surface of the water flowing in the conduit 220 and the lower end of the end 211 of the horn 210 contact each other. When the horn 210 vibrates ultrasonically, a portion of the water in the conduit 220 is sucked up to the horn 210 by the pumping effect. The water sucked into the horn 210 becomes a fog state by the ultrasonic vibration of the horn 210.

The misted water is sprayed from the spray port 250 to the outside of the ultrasonic unit 200 as indicated by the broken line M in FIG. 8A. Since the spray port 250 is arrange | positioned so as to oppose the inside of the rotating drum 120 of the washing | drying machine 1, the water in the mist state is supplied in the inside of the rotating drum 120. FIG.

In the lowermost part of the conduit 220, water in a non-fog state that is not in a fog state flows out of the spray port 250 to the outside of the ultrasonic unit 200, as indicated by arrow W in FIG. 8A. The water in the rain fog falls down from the spray port 250 by gravity.

As shown in FIG. 6, the water falling down from the spray port 250 is guide collar 116 disposed in the frame of the inner door 112 of the laundry dryer 1 below the spray port 250. ) And falls along the guide vane 116 between the outer circumferential surface of the rotary drum 120 and the inner circumferential surface of the water tank 130.

The washing stroke, rinsing stroke, dewatering stroke and drying stroke performed using the laundry dryer 1 configured as described above will be described below in the order of stroke.

First, the user opens the outer door 111 and the inner door 112, injects the fiber structure 2 from the inlet 113, and then closes the inner door 112 and the outer door 111. The user puts the detergent into the detergent case 470 and, if necessary, the finish agent in a finisher case (not shown). The finishing agent may be put in the middle of a washing stroke or a rinsing stroke.

Next, the user operates the operation panel to select washing and drying conditions. When the user operates the operation panel, the operation circuit 106 transmits a control signal to the main circuit 107, and the main circuit 107 controls each member of the laundry dryer 1. The main circuit 107 performs washing, rinsing, dehydrating and drying operations in accordance with the washing and drying conditions selected by the user. Depending on the washing and drying conditions selected by the user, a part of each stroke may not be performed. Here, the case where all the administration of a washing | cleaning stroke, a rinse stroke, a dehydration stroke, and a drying stroke is performed is demonstrated.

When the user presses the start button of the operation panel, the main circuit 107 is controlled to lock the outer door 111 and the inner door 112, and is controlled to open the water supply valve 401, Tap water is supplied into the water tank 130 from the water supply duct 420 via the water supply unit 410 and the detergent case 470. The water tank 130 is supplied with water mixed with the detergent contained in the detergent case 470. In this way, the washing process is started.

When it is detected by the water level sensor (not shown) that the water level in the water tank 130 reaches a predetermined value, the water supply valve 401 is closed. Subsequently, the circulation pump 460 is controlled to be driven. In addition, it is controlled to apply a voltage to the electrode 215 of the ultrasonic unit 200.

In addition, the main circuit 107 passes the dividing nozzle 450 through the dividing nozzle 450 so as to generate misty water using tap water rather than circulating water until the water level in the water tank 130 reaches a predetermined value. The water supply unit 410 may be controlled to supply the to the ultrasonic wave unit 200.

The water supplied into the water tank 130 is supplied to the flow dividing nozzle 450 by the circulation pump 460 through the internal drain hose 430 and the circulation hose 440. A part of the water supplied to the dividing nozzle 450 is supplied into the rotary drum 120 directly from the dividing nozzle 450. A part of the remainder of the water supplied to the dividing nozzle 450 is supplied from the dividing nozzle 450 to the ultrasonic unit 200 through the wet mist feed water hose 451.

In the ultrasonic unit 200, water containing detergent is supplied into the rotating drum 120 in a fog state. As the water containing the detergent becomes misted by ultrasonic waves, the detergent dissolves well in water, and the water containing the detergent penetrates well into the fiber structure 2.

The water supplied into the rotating drum 120 flows out into the water tank 130 through the small hole 121, and is circulated by the circulation pump 460 again.

The circulation pump 460 is driven for a predetermined time. In this way, even after the tap water is supplied to the water tank 130 to a predetermined level, the tap water flows out of the rotating drum 120 into the water tank 130 through the small hole 121, and the internal drainage hose ( Fog water is supplied into the rotating drum 120 using the circulating water supplied to the ultrasonic unit 200 through the jet nozzle 430 and the jet nozzle 450. When a predetermined time elapses, the main circuit 107 stops driving the circulation pump 460 and the ultrasonic unit 200 and controls the drain valve 432 to close.

Next, the rotary drum 120 is rotated by the drum rotation drive motor 140 in accordance with the rotation chart for the washing stroke.

In addition, about the rotation chart of the rotating drum 120, a rotation speed and a rotation period for every washing stroke, a rinsing stroke, a dehydration stroke, and a stroke of a drying stroke, or according to the kind of fiber structure 2 and the course of washing drying. , A plurality of rotation charts having different inversion cycles or the like are preset. The rotation chart is programmed to be selected by the user or automatically.

When the drum rotation drive motor 140 rotates forward and backward, the rotation drum 120 also rotates forward and backward. When the rotating drum 120 rotates, the operation | movement which the baffle 122 fixed to the inner peripheral wall surface of the rotating drum 120 raises the fiber structure 2, and falls below is repeated. In this way, the washing process is performed using the so-called blow washing effect. In addition, the circulation pump 460 may be driven in the washing stroke. When the circulation pump 460 is being driven, the ultrasonic unit 200 may be driven to supply misty water into the rotating drum 120. If the ultrasonic unit 200 is driven in accordance with the movement of the rotary drum 120, more effective cleaning can be achieved by reducing the remaining detergent and improving the penetration of the detergent into the fiber structure 2.

In the washing process, the water level is detected on the way, and when the water level becomes lower than the set water level, the replenishing water may be performed. In addition, when replenishing water is performed, the circulation pump 460 may be driven to supply water in a mist state from the ultrasonic unit 200 into the rotating drum 120. In the washing stroke, the misty water is supplied into the rotary drum 120, for example, for 5 minutes in total.

When the washing stroke is completed, the drain valve 432 is opened, and water is discharged from the external drain hose 431 out of the sheath 101. When the drainage is completed, the rotary drum 120 is subjected to an intermediate dewatering stroke which is rotated at a high speed in the rotation chart for the intermediate dewatering stroke. In the intermediate dewatering stroke, the water contained in the fiber structure 2 is transferred to the water tank 130 through a small hole 121 formed in the circumferential wall of the rotary drum 120 due to the centrifugal force caused by the high speed rotation of the rotary drum 120. It is discharged to the inner wall surface. Water flows downward through the inner wall surface of the water tank 130 and is discharged from the external drain hose 431 out of the sheath 101 through the drain valve 432.

When the intermediate dewatering stroke is finished, the program proceeds to the rinse stroke. After the drain valve 432 is closed, the water supply valve 401 is opened, and the tap water is supplied to the water tank 130 via the water supply unit 410. When it is detected by the water level sensor not shown that the water level in the water tank 130 has reached a predetermined value, the water supply valve 401 is closed.

After the water supply valve 401 is closed, the main circuit 107 is controlled to drive the circulation pump 460 for a predetermined time. At this time, the ultrasonic unit 200 may also be driven for a predetermined time.

When the circulation pump 460 and the ultrasonic unit 200 are driven, water in the water tank 130 circulates in the circulation channel and is supplied from the jet nozzle 450 to the ultrasonic unit 200 through the wet mist water supply hose 451. do. In the ultrasonic unit 200, the circulating water becomes a fog state and is supplied into the rotating drum 120.

In the rinsing cycle, since the tap water is freshly dehydrated once after the washing stroke, the detergent and the contaminant contained in the circulating water are relatively small. By supplying the circulating water to the ultrasonic unit 200 to generate misty water, detergent is supplied to the wet mist water supply passage 230, the conduit 220, and the horn 210 of the ultrasonic unit 200 in the washing stroke. It can be washed off even if contaminants are attached. Thus, the stroke which wash | cleans the contaminant component and detergent which adhered to the horn 210 may be performed in every rinsing stroke, when there are multiple rinsing strokes, but it is that a rinse is performed in the clean last rinse stroke. More effective.

In the rinsing stroke, instead of making the circulating water into a fog state, tap water may be supplied from the water supply unit 410 to the ultrasonic unit 200 by passing through the fractionation nozzle 450 to generate fog water.

After a predetermined time has elapsed since the start of driving the circulation pump 460 and the ultrasonic unit 200 or at the same time, the main circuit 107 controls the drum rotation drive motor 140 so that the rotary drum 120 rotates the drum. It is rotated along the rotation chart for a rinsing stroke by the drive motor 140. The intermediate dewatering stroke and the rinsing stroke are repeated a plurality of times and then proceed to the last rinsing stroke. In the final rinsing stroke, the water supply valve 401 is opened, and the flexible finishing agent placed in the detergent case 470 is supplied from the water supply duct 420 to the water tank 130 as water containing the flexible finishing agent.

When the last rinse stroke is completed, the drain valve 432 is opened so that the rinse liquid is discharged from the outer drain hose 431 out of the sheath 101. When the drainage is completed, the rotary drum 120 is rotated at high speed according to the rotation chart for the last dewatering stroke, and the final dewatering stroke is performed. In the final dewatering stroke, similarly to the intermediate dewatering stroke, the rinse liquid contained in the fiber structure 2 is formed by the centrifugal force by the high speed rotation of the rotary drum 120 to open the small hole 121 formed in the circumferential wall of the rotary drum 120. It is discharged to the inner wall surface of the water tank 130 through.

When the final dewatering stroke is completed, the process shifts to the drying stroke. In the drying stroke, the rotary drum 120 is rotated and the PTC heater 315 and the blower motor 313 are driven. In addition, when performing a washing and drying process continuously, you may drive the PTC heater 315 from the last dehydration stroke. By doing in this way, the temperature in the rotating drum 120 rises, it dehydrates more and it becomes possible to perform drying efficiently.

By driving the PTC heater 315 and the blower motor 313, the air heated by the PTC heater 315 flows as shown by the double-dotted line arrow in FIG. 3 and FIG. 130 and into the rotary drum 120. The warm air is discharged to the outside of the rotating drum 120 through the small hole 121 after contacting the fiber structure 2 in the rotating drum 120, and formed in the lower portion of the water tank 130. It is exhausted to the cooling duct 330 through. The gas exhausted by the cooling duct 330 has high humidity due to the moisture contained in the fiber structure 2 in the rotary drum 120. Air containing moisture is cooled by the cooling duct 330 and dehumidified. Water removed from the gas is returned to the water tank 130 from below the cooling duct 330 and discharged from the sheath 101 through the internal drain hose 430, the drain valve 432, and the external drain hose 431. do.

The air dehumidified in the cooling duct 330 is returned to the air supply duct 310 through the exhaust duct 320. In the air supply duct 310, it is heated by the PTC heater 315. By repeating this cycle, a drying process is performed.

In the drying stroke, when a predetermined time has elapsed since the driving of the PTC heater 315 is started, the water supply valve 401 is opened to control the ultrasonic unit 200 to be driven. At this time, it is preferable that the main circuit 107 stops the driving of the PTC heater 315 so that the ultrasonic unit 200 is driven at a high temperature and the operation is unstable due to a change in temperature characteristics.

When the water supply valve 401 is opened, tap water is supplied from the water supply unit 410 to the ultrasonic unit 200 through the dry mist water supply hose 411. In the ultrasonic unit 200, the tap water becomes a fog state and is supplied into the rotating drum 120.

At this time, the water supply unit 410 adjusts the amount of water by the water mist valve 413 for dry mist so as to supply a relatively small amount of water to the ultrasonic unit 200. In addition, the main circuit 107 supplies the water supply unit 410 and the dry mist water supply valve so that the water supply to the ultrasonic unit 200 and the ultrasonic vibration of the horn 210 of the ultrasonic unit 200 are intermittently performed. 413 and the ultrasonic unit 200 is controlled. In this way, in the drying stroke, a small amount of misty water is intermittently supplied into the rotary drum 120. The misty water in a drying stroke is supplied into the rotating drum 120, for example for 10 minutes.

The humidity detection means is provided in the water tank 130, and the drive of the ultrasonic unit 200 may be controlled so that humidity may be adjusted. For example, the ultrasonic unit 200 may be driven when the humidity in the water tank 130 detected by the humidity detecting means is equal to or less than a predetermined humidity.

The ultrasonic wave unit 200 does not allow water to pass through the small hole but makes the water mist by the ultrasonic vibration of the horn 210, so that the water in the mist state is generated even if the amount of water supplied is low and the water pressure is low. The rotary drum 120 may be supplied. That is, in order to adjust the humidity in the water tank 130, even if the amount of water is increased or decreased, it is possible to stably generate misty water.

Since the water in the fog state generated by the ultrasonic vibration in the horn 210 of the ultrasonic unit 200 does not have high straightness, the specific part is not wetted in the rotary drum 120.

In addition, the water of the non-fog state which does not become a fog state in the ultrasonic unit 200 falls down by gravity from the spray port 250 of the ultrasonic unit 200. The water of the rain fog falling down from the spray port 250 reaches the guide vane 116, is guided to the guide vane 116, and does not enter the inside of the rotary drum 120. It falls between the outer peripheral surface and the inner peripheral surface of the water tank 130. Therefore, the water in the non-fog state does not wet the fiber structure 2 in the rotating drum 120.

In this way, in the drying stroke, by supplying a small amount of misty water into the rotary drum 120 intermittently, the humidity in the rotary drum 120 is appropriately adjusted, and the fiber structure 2 is wrinkled by overdrying. This can be prevented from occurring.

After driving the ultrasonic unit 200 for a predetermined time, the main circuit 107 stops driving the ultrasonic unit 200 and controls the PTC heater 315 to be driven. When the predetermined time has elapsed, the main circuit 107 stops driving of the PTC heater 315, performs only the blowing by the blowing fan 312 for a predetermined time, cools the fiber structure 2, and ends the drying stroke. The fiber structure 2 can be taken out later.

In addition, in a drying process, you may supply the mist state of water in the rotating drum 120 in multiple times.

When blowing with the blowing fan 312 is performed for a predetermined time, the main circuit 107 stops driving the blowing motor 313. In this way, the drying process is completed. When the drying stroke is finished, all the laundry drying strokes are finished.

As described above, the laundry dryer 1 includes the rotary drum 120 for accommodating the fiber structure 2 and the ultrasonic unit 200 for supplying the water into the rotary drum 120 in a state of fog by ultrasonic waves. It is provided.

In the case of making water into a fog state by ultrasonic waves, by adjusting the frequency of the ultrasonic waves, the amount of water in the fog state, the particle size of the water in the fog state, and the timing of generating the water in the fog state can be adjusted. Since the water pressure is not required to be at least a constant in order to mist the water, the water can be misted regardless of the environment in which the laundry dryer 1 is installed. Since there is no need to increase the water pressure, it is circulated by a small pump or the like, so that water in a mist state can be generated even by using a circulation water that is difficult to increase the water pressure.

In addition, in order to make the water misty, it is not necessary to pass the water through a small hole, so even if the wash water contains solids or deposits such as fibers, garbage, or detergent, the hole is clogged to generate misty water. There is no possibility of becoming impossible, and it can generate | occur | produce mist state stably. Therefore, in the washing dryer 1 which circulates the water in the rotating drum 120, even if circulating water is used, the water of a mist state can be produced stably. In addition, even when water, such as the remaining water in a bathroom, or waste water such as hair, is used, water in a stable state can be generated.

In addition, the water misted by the ultrasonic wave has low linearity, so that when the fiber structure 2 is supplied into the rotating drum 120 in which the fiber structure 2 is housed, the fiber does not wet only a specific portion of the fiber structure 2, The whole structure 2 can be wetted.

By doing in this way, the laundry dryer 1 which can generate | occur | produce the water of stable fog state can be provided, without being influenced by the environment where the laundry dryer 1 is installed.

In addition, in the laundry dryer 1, the ultrasonic unit 200 supplies water into the rotating drum 120 in a mist state in the washing stroke which wash | cleans the fiber structure 2 with water and a detergent at least.

By doing in this way, the whole fiber structure 2 becomes easy to become familiar with water and a detergent, and a washing power can be improved. In addition, by making the water containing the detergent into a mist state by ultrasonic waves, it is possible to dissolve the detergent in water well by the emulsification action.

It is possible to supply the fiber structure 2 without leaving fog of an appropriate particle size.

In the laundry dryer 1, the ultrasonic unit 200 supplies the water into the rotating drum 120 in a mist state in a washing stroke in which at least the fiber structure 2 is washed with water and a detergent.

By doing in this way, the whole fiber structure 2 becomes easy to become familiar with water and a detergent, and a washing power can be improved. In addition, by making the water containing the detergent into a mist state by ultrasonic waves, it is possible to dissolve the detergent in water well by the emulsification action. In addition, since water particles are small in the water of the mist state, the permeability to the fiber structure 2 is good, and the washing | cleaning power of the water used for washing can be improved by supplying the water with which detergent was melt | dissolved in the rotating drum 120. FIG.

In addition, in the washing machine 1, the ultrasonic unit 200 supplies water into the rotating drum 120 in a rinsing step of rinsing the fiber structure 2 washed in the washing step with water.

In addition, by supplying water in the mist state in the rotary drum 120 in the rinsing stroke, the particles of the water are made small to improve permeability, and the detergent attached to the fiber structure 2 or the rotary drum 120 can be dropped well. Can be.

In addition, as described above, the ultrasonic unit 200 is a wet mist for supplying water into the conduit 220 along the tangential direction of the conduit 220 for distributing water and the inner circumferential surface 221 of the conduit 220. The water supply path 230, the dry mist water supply path 240, and the horn 210 are disposed inside the conduit 220 to mist the water by ultrasonic waves.

Water is supplied from the wet mist water supply path 230 and the dry mist water supply path 240 into the conduit 220 along the tangential direction of the inner circumferential surface 221 of the conduit 220, so that the water is the conduit 220. It is difficult to directly contact the horn 210 disposed in the). Since water is difficult to directly contact the horn 210, it becomes difficult to form a water film covering the surface of the horn 210.

By doing in this way, the ultrasonic unit 200 which can generate | occur | produce water of a stable fog state can be provided.

In addition, in the ultrasonic unit 200, the horn 210 has an end portion 211 formed in a plate shape, and the end portion 211 has an end surface 216 on the long side and an end surface on the short side ( The horn 210 is arrange | positioned in the pipeline 220 so that the end surface 212 of the short side of the edge part 211 may extend in the pipeline 220 along the direction where water collects.

The water in the mist state is generated at the end 211 of the horn 210 formed in a plate shape. As the end 211 of the horn 210 is arrange | positioned so that the end surface 212 of the short side may extend along the direction where water gathers in the conduit 220, the horn 210 is a predetermined amount of water. It is sucked up by the pumping effect and misted.

For example, if the horn 210 is arranged such that the end face 212 on the short side of the end 211 of the horn 210 extends along the horizontal plane, it is generated by the amount of water gathered in the conduit 220. The amount of fog is greatly changed.

Therefore, the horn 210 has the end 211 formed in plate shape, and the horn so that the end surface 212 of the short side of the end 211 may extend along the direction where water gathers in the conduit 220. Since the 210 is disposed in the conduit 220, even if the amount of water in the conduit 220 changes, it is possible to stably generate misty water.

In addition, the ultrasonic unit 200 includes a rib 222 that protrudes from the inner circumferential surface 221 of the conduit 220 toward the inside of the conduit 220.

In this way, the water supplied into the conduit 220 along the tangential direction of the inner circumferential surface 221 of the conduit 220 collides with water flowing along the inner circumferential surface 221 of the conduit 220 to the rib 222 to weaken the momentum. It is possible to prevent the water level from becoming too high, the water level becomes too high, the oscillation of the ultrasonic wave becomes abnormal, and the water cannot be made into a fog state. In addition, when there is momentum in the water flow, water can be prevented from directly contacting the horn 210 away from the inner circumferential surface 221 of the conduit 220.

An ultrasonic unit 200 is provided for supplying the water in the flow path into the rotating drum 120 by making the mist state by ultrasonic waves.

In the case where the water is in the fog state by the ultrasonic waves, the amount of water in the fog state, the particle size of the water in the fog state, and the timing of generating the water in the fog state can be adjusted by adjusting the water supply or the frequency of the ultrasonic waves. Since the water pressure is not required to be at least a constant in order to mist the water, the water can be misted regardless of the environment in which the laundry dryer 1 is installed.

In addition, the water misted by the ultrasonic wave has low linearity, so that when supplied into the rotating drum 120 in which the fiber structure 2 is housed, the water is rotated without wetting only a specific portion of the fiber structure 2. The humidity in the drum 120 can be increased.

In addition, by making the flowing water in the water supply flow path into the fog state, water containing no bacteria or the like can be supplied into the rotating drum 120 in the fog state.
