The present invention relates to a laundry dryer which can collectively carry out laundry from drying in a inner tank rotatably embedded in an outer tank from washing to drying.

Conventionally, this type of laundry dryer has been constructed as shown in FIG. The structure is demonstrated below.

As shown in FIG. 20, the inner side tank 1 comprises the dehydration tank for combined use for washing | cleaning, is formed in substantially cylindrical shape, and is rotatably built in the outer side tank 2. A fluid balancer 3 is formed on the upper side of the inner jaw 1, and a pulsator 4 is rotatably formed on the inner bottom. The outer jaw 2 is suspended from the main body 6 by the suspension mechanism 5 and is dust-tightly supported. A motor 7 is formed at the bottom of the outer jaw 2. The motor 7 has a pulsator 4 incorporating a clutch for converting rotational force transmission from a hollow to a two-axis washing and dewatering shaft 8 in response to washing or dehydration, and a mechanism for transmitting rotation. Or the inner jaw 1 is rotated. The drainage passage 9 is connected to the bottom surface of the outer jaw 2 via the drainage cock 10. The warm air blowing means 11 blows the warm air for drying by embedding a drying blower and a heater (not shown), and is configured to be mounted on the outer tank 2 to blow the warm air into the inner tank 1 have.

The operation in the above configuration will be described. In the washing stroke, when the laundry 12 and the detergent are put into the inner tank 1, and water or hot water is supplied to start operation, the clutch built in the motor 7 is switched to rotate the pulsator 4, The power of the motor 7 is transmitted to the pulsator 4 via the washing shaft, and the laundry 12 is stirred and washed by the pulsator 4 by rotating the pulsator 4.

In the dehydration stroke, after the washing is finished, the drain cock 10 is opened to drain the water in the inner tank 1, and then the transmission of the power of the motor 7 is transferred to the dehydration side by a clutch built in the motor 7. By switching, the power of the motor 7 is transmitted to the inner tank 1 via dehydration and rotated to dehydrate by applying a centrifugal force to the laundry 12.

In the drying stroke, the warm air is injected from the warm air blowing means 11 into the inner tank 1 while the pulsator 4 is rotated in the normal mode, and the laundry 12 is dried by the warm air.

In such a conventional configuration, since the warm air injected from the warm air blowing means 11 into the inner tank 1 does not spread widely throughout the inner tank 1, and especially does not spread sufficiently in the lower layer part, the warm air The heat and flow rate of the oil cannot be efficiently applied to the laundry 12, which requires a long time for drying, and dry unevenness may occur. In addition, since the hot air blowing means 11 is attached to the outer jaw 2, the outer jaw 2 suspended from the main body 6 by the suspension mechanism 5 and the warm air blowing means 11 are included. The weight of the vibrating body was so large that there was a problem that vibration during operation, in particular in the dehydration stroke, became large.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to shorten drying time, to reduce drying unevenness of clothes, to improve drying efficiency, and to reduce vibration during operation, particularly in a dehydration stroke.

In order to achieve the above object, the present invention, by inserting the laundry into the inner tank of the inner cylindrical shape to rotate about the vertical axis, the inner tank, rotatably disposed stirring means for stirring the laundry in the inner tank, The bath or agitating means is rotated by a motor and the hot air supplied from the hot air supply path into the inner tank is heated by the heating means, and the hot air is supplied into the inner tank by the drying blower. Operation of the heating means, the drying blower, and the like are controlled to control the respective steps of washing, rinsing, dehydration and drying. In the drying process, the laundry is stirred by the stirring means, the warm air heated by the heating means is sprayed to the laundry in the inner tank by a drying blower, dehumidified and dried, and the drying time can be shortened. The drying nonuniformity can be reduced to improve the drying efficiency, and the vibration can be reduced during operation, especially in the dehydration stroke.

Further, preferably, the outer side jaws are connected to the warm air supply passage even when the inner jaw rotates at a high speed by a dehydration stroke by connecting the warm air supply passage to the outer jaw by a flexible tube and supplying warm air into the inner jaw. By virtue of not being pulled in one horizontal direction by the vibration, the vibration of the outer jaw due to the high speed rotation of the inner jaw is uniformly transmitted to the main body, thereby reducing the overall vibration.

Further, preferably, the water supply of the inner jaw is connected by covering the upper portion of the outer jaw with an inner partition plate that prevents air leakage and connecting a water supply valve for supplying water to the inner jaw with a water supply port formed in the inner partition plate with a water supply duct. Since it can be carried out through the water supply duct and the drying stroke can prevent the leakage of warm air, the drying performance can be improved and the humidity of the room can be prevented from being increased due to the leakage of the warm air.

A first embodiment of the present invention will be described with reference to FIG.

As shown in FIG. 1, the inner jaw 13 constitutes a washing / dehydration tank, which is formed in a substantially cylindrical shape having a plurality of small holes (not shown) on its side and is embedded in the outer jaw 14. It is configured to rotate about an approximately vertical axis. A fluid balancer 15 is formed on the upper side of the inner jaw 13, and a pot-shaped pulsator (stirring means) 16 is rotatably formed on the inner bottom. The pulsator 16 has the inclined surface 17 in the outer peripheral part, and forms the plurality of radial rib 18 which passes through this inclined surface 17 and reaches substantially an outer edge. The outer jaw 14 is suspended from the main body 20 by the suspension mechanism 19 and is dust-proof supported. A motor 21 is formed at the bottom of the outer jaw 14. The motor 21 has a built-in pulsator 16 incorporating a clutch for switching the transmission of rotational force to the washing shaft and the dewatering shaft in response to washing and dehydration, washing or dehydration, and a mechanism for transmitting rotation therein. ) Or the inner jaw 13 is rotated. The drainage passage 22 is connected to the bottom surface of the outer jaw 14 via the drainage cock 23.

The hot air supply passage 24 supplies the warm air into the inner tank 13 in a drying stroke, and includes a heater (heating means) 25 that heats the warm air and a drying blower 26 that supplies the warm air into the inner tank 13. ) Is fixed to the main body 20. This hot air supply passage 24 is connected to an inner partition plate 28 formed on the upper side of the outer jaw 14 via a bellows-shaped stretchable tube 27. Moreover, the connection duct 29 which returns a warm air to the bottom surface of the outer side tank 14 is formed. This connection duct 29 is connected to the heat exchanger 31 via the switch drain cock 30, and also via a hot air supply passage 24 having a heater 25 and a blower 26 for drying, and thus a flexible tube. It is connected to the outer jaw 14 via the 27. The inner partition plate 28 is provided with a lid 32 that can be opened and closed. The inner partition plate 28 is fixed to cover the upper surface of the outer jaw 14, prevents the warm air from leaking upward, and opens and closes the lid 32 that can open and close the laundry. And the circulation path which is substantially closed by the connection duct 29, the heat exchanger 31, the warm air supply path 24, etc. is formed. Here, the flexible tube 27 and the connection duct 29 are elastically connected to the main body (fixed side) 20 and the outer side jaw (vibration side) 14. In addition, the heat exchanger 31 is provided outside the main body 20 so as to exchange heat by air cooling, and the drain hole 33 is formed in the lower part of the heat exchanger 31.

The control means 34 controls operations of the motor 21, the drain cock 23, a water supply valve (not shown), and the like to control washing, rinsing, and dehydration strokes, and at the same time, the motor 21 and the heater. (25), the drying blower 26 or the like is controlled to control the drying stroke. In the drying process, the laundry 35 is stirred by the pulsator 16 and the warm air heated by the heater 25 is transferred to the laundry 35 in the inner tank 13 through the drying blower 26. It sprays and dehumidifies and heats by heat exchange with the heat exchanger 31, and is comprised. The control means 34 is configured to control the rotation speed of the pulsator 16 in the washing stroke to be higher than the rotation speed of the pulsator 16 in the drying stroke.

The operation in the above configuration will be described. First, from the washing to the dehydration stroke, the opening and closing lid 32 is opened, the laundry 35 and the detergent are introduced into the inner tank 13, and operation starts. After watering up to a predetermined water level, the pulsator 16 is rotated to perform a washing stroke. After the washing stroke, a rinsing stroke similar to the washing stroke is executed. At this time, the water in the outer side tank 14 is not discharged | emitted from the drain hole 33 by closing the switching drain cock 30. Next, the dewatering stroke proceeds, the normal operation of opening the drainage cock 23 to rotate the inner jaw 13 at high speed and dewatering is carried out in a drying stroke.

In the drying stroke, the drain cock 23 is closed and the switching drain cock 30 is opened, and the warm air is stretched and contracted by the heat generation of the heater 25 and the blowing operation of the drying blower 26. It is sent to the inner jaw 13. The laundry 35 which is dehydrated and stuck to the inner wall of the inner jaw 13 falls off by the rotation of the pulsator 16, and thereafter, by the rotation of the pulsator 16 in the inner jaw 13. The upper surface of the pulsator 16 is rotated along the inclined portion 17 so as to be lifted upward by the radial rib 18 and stirred. Warm air reaches the laundry 35 which has been raised upward. Then, the warm air evaporates the moisture of the laundry 35 to dry the laundry 35, and the hot air is a high-humidity hot air, which is formed between the hole on the side of the inner jaw 13 or the fluid balancer 15 and the inner partition plate 28. It passes through the space between the outer wall of the inner jaw 13 and the inner wall of the outer jaw 14, and enters the connection duct 29 below the outer jaw 14. Then, as shown by the arrow, it passes through the heater 25 through the heat exchanger 31, and reaches the drying blower 26 again. During this process, the hot air of high humidity contacts the inner wall of the outer tank 14, the inner wall of the heat exchanger 31 constituting a part of the circulation path, and the like, so that these surfaces are heat exchanged and dehumidified to reach the heater 25. At that time, it is cooled dry air. Drying advances by repeating that this dry air is heated by the heater 25 and touches the laundry 35 again.

At this time, the warm air circulates through the circulation path formed by the connection duct 29, the heat exchanger 31, the warm air supply path 24, and the like, and the circulating warm air is directed toward the downward switching drain cock 30. It can pass evenly between every laundry 35 in the tank 13 to every corner, and can dry in the state without drying nonuniformity. In addition, since the heat exchanger 31 constituting a part of the circulation path is installed outside the main body 20, the surface thereof is always cooled, and the heat exchanger 31 can be dried quickly by efficiently performing dehumidification. The dehumidifying water generated by the heat exchange in the heat exchanger 31 can be discharged from the drain hole 33.

As mentioned above, in the drying process, the laundry 35 is stirred by the pulsator 16, and the warm air heated by the heater 25 is wash | cleaned in the inner tank 13 by the drying blower 26. And the heat exchanger 31 is dehumidified and dried by heat exchanger 31, so that the heat exchanger 31 can heat exchange the heat exchanger 31, and heat exchanges the inside of the outer tank 14 as well. It is possible to shorten the drying time, to reduce the drying unevenness of the laundry 35 to improve the drying efficiency, and also to provide a hot air supply passage 24 incorporating a heater 25 and a drying blower 26. Since the heat exchanger 31 and the like are not attached to the outer tank 14, the vibrations during operation, particularly in the dehydration stroke, can be reduced.

Moreover, the warm air supply path 24 forms the circulation path which blows in the air in the inner side tank 13, and circulates the warm air heated by the heater 25 to the inner side tank 13, The inside of the outer side tank 14, or Since heat exchange is performed by the heat exchanger 31 formed in the circulation path, the heat exchange performance can be improved, and a compact and good drying efficiency can be obtained. In addition, since the heat exchanger 31 is provided outside the main body 20 and configured to heat exchange by air cooling, heat exchange proceeds while the hot air is circulated in the circulation path including the heat exchanger 31, Thereby, the washing dryer which is compact and is excellent in drying efficiency can be obtained.

In addition, the pulsator 16 is rotatably disposed on the inner bottom of the inner jaw 13, has an inclined surface 17 on the outer circumference thereof, and radial ribs passing through the inclined surface 17 to reach an approximately outer edge. Since the plural number 18 is formed, the laundry 35 is lifted upward by the radial rib 18 and stirred with the rotation of the pulsator 16, and the laundry 35 is lifted upwards. Since the warm air can reach the drying efficiency, the drying time can be shortened, and the drying unevenness of clothes can be reduced, and the control means 34 differs in the rotation speed of the pulsator 16 by the washing stroke and the drying stroke. Since the pulsator 16 is driven at the optimum rotational speed in the washing stroke and the drying stroke, both the washing efficiency and the drying efficiency can be improved.

In this embodiment, the heat exchanger 31 connected to the outer tank 14 via the connection duct 29 is connected to the hot air supply passage 24 to form a closed circulation path. The same effect can be acquired even if it is comprised so that a closed circulation path may not be formed without connecting the hot air supply path 24.

It connects to the supply path 24, and comprises the circulation path which circulates the warm air heated by the heater 25, and heat-exchanges the high humidity hot air by air cooling and dehumidifies. This heat exchanger 38 is formed in the corner portion of the main body 37. Since other configurations are the same as those in the second embodiment, the same reference numerals will be given and the description thereof will be omitted.

The operation in the above configuration will be described. In addition, since the operation | movement from washing process to dehydration process is the same as that of the said 2nd Example, description is abbreviate | omitted.

When the transition to the drying stroke is performed after the dehydration stroke, the high-humidity warm air contacts the inner wall of the outer tank 14, the inner wall of the heat exchanger 38 constituting a part of the circulation path, and the like. When it reaches the heater 25, it becomes cooling dry air. Drying advances by repeating that this dry air is heated by the heater 25 and touches the laundry 35 again. Here, since the heat exchanger 38 is provided in the corner part of the main body 37, the whole can be comprised compactly.

In addition, since the heat dissipation performance by the heat dissipation fin 39 improves by forming the some heat dissipation fin 39 in the outer wall of the heat exchanger 38 which comprises a circulation path as shown in FIG. 5, a heat exchanger ( The heat exchange performance of 38) can be remarkably improved, and a laundry dryer having a compact and good drying efficiency can be obtained.

In addition, although the heat radiation fin 39 is formed in the outer side wall of the heat exchanger 38 in FIG. 5, the same effect can be acquired even if it forms in the inner side wall of the heat exchanger 38. As shown in FIG.

Next, a fourth embodiment of the present invention will be described with reference to FIG.

As shown in FIG. 6, the outer side jaw 40 protrudes the pin-shaped guide wall 41 at the position which opposes the cooling blower 36 on the outer wall surface, and this guide wall 41 is carried out. By inducing outside air and dissipating heat at the same time. Since other configurations are the same as those in the second embodiment, the same reference numerals will be given and the description thereof will be omitted.

The operation in the above configuration will be described. In addition, since the operation | movement from washing process to dehydration process is the same as that of the said 1st Example, description is abbreviate | omitted.

When the transition to the drying stroke is performed after the dehydration stroke, the high-humidity warm air is brought into contact with the inner wall of the outer tank 40, the inner wall of the heat exchanger 31 constituting part of the circulation path, and the like. When it reaches (25), it becomes cooling dry air. Drying advances by repeating that this dry air is heated by the heater 25 and touches the laundry 35 again. Here, by the guide wall 41 formed in the side wall of the outer side tank 40, the blowing by the cooling blower 36 spreads widely along the guide wall 41 to the whole surface of the outer side chamber 40. As shown in FIG. For this reason, the heat dissipation in the surface of the outer side tank 40 is carried out by the guide wall 41 using a fin, and airflow spreads widely along the guide wall 41 to the whole surface of the outer side tank 40.

Next, a fifth embodiment of the present invention will be described with reference to FIG.

As shown in FIG. 7, the heat exchanger 42 has a water supply unit 43 and is configured to dehumidify by heat-cooling by water cooling. The hot air supply passage 24 includes a heater 25 and a drying blower 26. It is connected to the inner partition plate 28 formed in the upper part of the outer jaw 14 via the bellows-shaped stretchable tube 44 inside. And the circulation path which is substantially closed by the connection duct 29, the heat exchanger 42, the warm air supply path 24, etc. is formed. Here, the bellows-shaped stretchable tube 44 is provided in a substantially vertical direction. Since other configurations are the same as those in the first embodiment, the same reference numerals are used and description thereof will be omitted.

The operation in the above configuration will be described. In addition, since the operation | movement from washing process to dehydration process is the same as that of the said 1st Example, description is abbreviate | omitted.

In the drying stroke, the switching drain cock 30 is opened, and the warm air is sent to the inner tank 13 through the tube 44 that can be warmed by the heating of the heater 25 and the blowing operation of the drying blower 26. . The laundry 35 dehydrated is removed by the rotation of the pulsator 16, and then lifted upward by the radial ribs 18 during the rotation of the pulsator 16 in the inner jaw 13. It is stirred and stirred. The warm air touches the laundry 35 placed upward. Therefore, the warm air removes the moisture of the laundry 35 to become a high humidity warm air, and passes through the space between the outer wall of the inner jaw 13 and the inner wall of the outer jaw 14 through the side of the inner jaw 13 to the outside. It enters into the connection duct 29 of the lower part of the tank 14. Then, as shown by an arrow, it passes through the heater 25 through the heat exchanger 42, and reaches the drying blower 26 again. During this process, the hot air of high humidity is passed by the heat exchanger 42 and cooled by the water supplied from the water supply 43 to remove moisture.

It enters into the inside jaw 13 via the inside. Here, in the present embodiment, since the hollow passage 45 is formed up to the substantially center portion of the inner partition plate 47, the warm air travels along the hollow passage 45 to the approximately center portion of the inner partition plate 47. Moreover, since the guide part 48 is formed in the exit part of the hollow channel | path 45, warm air is supplied into this inner tank 13 toward the downward direction along this guide part 48. As shown in FIG. Thereby, the warm air can efficiently contact the laundry 35 in the inner tank 13, can dry efficiently, can shorten the drying time, and can shorten the finishing time from washing to drying.

Next, a seventh embodiment of the present invention will be described with reference to FIG.

As shown in FIG. 9, the flexible tube 49 forms a check valve 50 therein, and the check valve 50 flows warm air from the hot air supply passage 24 toward the inner tank 13. It is configured to open when closed and close when flowing in the reverse direction. Since other configurations are the same as those of the fifth embodiment, the same reference numerals are used and the description thereof will be omitted.

The operation in the above configuration will be described. In addition, since the operation | movement from washing process to dehydration process is the same as that of the said 5th Example, description is abbreviate | omitted.

In the drying stroke, the switching drain cock 30 is opened, and the warm air passes through the flexible tube 49 through the hot air supply passage 24 by the heat generation of the heater 25 and the blowing operation of the drying blower 26. The inner partition 13 enters the inner jaw 13 through the inner partition plate 28. At this time, for example, in a washing stroke or the like, moisture or soap bubbles pass through the flexible tube 49 to penetrate into the inside of the warm air supply passage 24, that is, the drying blower 26 or the heater 25. Invasion can be prevented by the check valve 50. As a result, the backflow of unnecessary things can be eliminated and safety can be improved.

Next, an eighth embodiment of the present invention will be described with reference to FIG.

As illustrated in FIG. 10, the outer jaw 51 rotates about an approximately vertical axis and incorporates an inner jaw 13 constituting the washing / dehydration tank, which is suspended on the main body 52 by the suspension mechanism 19. It is dustproof and is supported. The hot air supply passage 53 supplies the warm air into the inner tank 13 in a drying stroke, and provides a heater 25 for heating the warm air and a drying blower 26 for supplying the warm air into the inner tank 13. It is built in and connected to the main body 52. The flexible tube 54 is formed to cover the outer circumference of the laundry inlet 55 of the inner jaw 13 and connects the outer jaw (vibration side) 51 and the main body (fixed side) 52. Since other configurations are the same as those in the first embodiment, the same reference numerals are used and description thereof will be omitted.

In the dehydration stroke, after the washing stroke is finished, the drain cock 23 is opened to drain the water in the inner tub 13, and then the clutch built in the motor 21 is switched to the dehydration side, and the power of the motor 21 is dehydrated. The inner jaw 13 is rotated by passing it to the inner jaw 13. Thereby, it dehydrates by the centrifugal force which generate | occur | produces. Vibration occurs in the outer jaw 51 supported by the suspension mechanism 19 by the rotation of the inner jaw 13 at this time. This vibration is transmitted to the main body 52 so that the main body 52 of the dehydration stroke vibrates.

Here, since the outer side jaw (vibration side) 51 and the main body (fixed side) 52 are connected by the flexible tube 54, the outer side jaw (vibration side) 51 is connected to the main body (fixed side) ( The vibration transmitted to 52 can be absorbed by the flexible tube 54 to suppress the vibration of the main body 52. Moreover, since the flexible tube 54 is formed so as to cover the outer circumference of the laundry inlet 55, since there is no effect of the force pulled in one direction and it is arranged in a good balance, vibration can be suppressed less.

In the drying stroke, the switching drain cock 30 is opened, and the warm air is passed through the flexible tube 54 by the heat generation of the heater 25 and the blowing operation of the drying blower 26 to the inner tank 13. Lose. The laundry 35 which is dehydrated and stuck to the inner wall of the inner jaw 13 is removed by the rotation of the pulsator 16, and then the rotation of the pulsator 16 in the inner jaw 13. By rotating along the inclination part 17 of the pulsator 16, it raises upwards by the radial rib 18, and is stirred. Warm air reaches the laundry 35 which has been raised upward. The warm air removes moisture from the laundry 35 to become a high humidity warm air, and passes through the side surface of the inner jaw 13 and passes through a space between the outer wall of the inner jaw 13 and the inner wall of the outer jaw 51. Thus, the lower portion of the outer jaw 51 enters the connecting duct 29. Then, as shown by an arrow, it passes through the heater 25 via the heat exchanger 31, and comes in contact with the drying blower 26 again. During this process, the high-humidity warm air reaches the inner wall of the outer tank 51, the inner wall of the heat exchanger 31 constituting a part of the circulation path, and the like, so that they are heat exchanged and dehumidified on their surfaces to reach the heater 25. At that time, it is cooled dry air. Drying advances by repeating that this dry air is heated by the heater 25 and touches the laundry 35 again.

In this way, the outer tube (vibration side) 51 and the main body (fixed side) 52 are connected by the flexible tube 54 so as to cover the laundry inlet 55, so that the flexible tube 54 can be balanced well. The vibration when the pulsator 16 or the inner jaw 13 rotates can be suppressed less by each stroke of washing, rinsing, dehydration and drying.

Next, a ninth embodiment of the present invention will be described with reference to FIG.

As shown in FIG. 11, the inner partition board 57 which has the warm air inflow port 56 in the upper part of the outer side tank 51 is formed. Since other configurations are the same as those of the eighth embodiment, the same reference numerals will be given and the description thereof will be omitted.

The operation in the above configuration will be described. In addition, since the operation | movement from washing | cleaning stroke to a dehydration stroke is the same as that of the said 8th Example, description is abbreviate | omitted.

In the drying stroke, the switching drainage cock 30 is opened, and the warm air is blown through the warm air supply passage 53 by the heating operation of the heater 25 and the blowing operation of the drying blower 26. It passes through the inner partition plate 57 and enters the inside of the inner jaw 13, raises the temperature in the inner jaw 13, and washes the laundry by contacting the warm air and the laundry 35 by the rotation of the pulsator 16. (35) is dried. At this time, the warm air inlet 56 allows the direction of the warm air to be vertically downward at a position close to the laundry 35 so that hot air of high temperature can be brought into contact with the laundry 35 to promote drying of the laundry 35. do.

Thus, by forming the inner partition plate 57 having the warm air inlet 56 and making the direction of the warm air vertically downward at a position close to the laundry 35, the hot air of high temperature can be brought into contact with the laundry 35. Drying time can be shortened.

Next, a tenth embodiment of the present invention will be described with reference to FIG.

As shown in FIG. 12, the inner partition board 59 which has the warm air inflow port 58 is formed in the upper part of the outer side tank 51, and the shape of the warm air inflow port 58 is made into the throttle shape. Since other configurations are the same as those of the ninth embodiment, the same reference numerals are used and the description thereof will be omitted.

The operation in the above configuration will be described. In addition, since the operation | movement from washing | cleaning stroke to a dehydration stroke is the same as that of the said 9th Example, description is abbreviate | omitted.

In the drying stroke, the switching drainage cock 30 is opened, and the warm air is blown through the warm air supply passage 53 by the heating operation of the heater 25 and the blowing operation of the drying blower 26. It passes through the inner partition plate 59 to enter the inside of the inner jaw 13, and raises the temperature in the inner jaw 13 to contact the warm air and the laundry 35 by the rotation of the pulsator 16 to wash the laundry. (35) is dried. At this time, since the hot air inflow port 58 has a throttle shape, the hot air is blown so as to be injected at high speed in the vertical downward direction. For this reason, the high temperature warm air can be made to contact with the laundry 35 finely, and the drying of the laundry 35 is accelerated | stimulated.

Thus, by making the shape of the warm air inflow port 58 into a throttle shape, the direction of the warm air at the time of drying can be sprayed at high speed vertically downward, and the warm air of high temperature is washed hard and the laundry 35 below the inner tank 13 is carried out. ), The drying time of the laundry 35 can be shortened.

Next, an eleventh embodiment of the present invention will be described with reference to FIG.

As shown in FIG. 13, the blower outlet 60 injects warm air from the warm air supply path 61 into the inner tank 13 through the flexible tube 62. FIG. The inner partition plate 63 is attached to the upper surface of the outer jaw 14, and the cover 64 is attached to the inner partition plate 63 so as to be openable and openable. The blower outlet 60 is comprised so that it may be fixed to the cover 64, and the cross section area is made small toward the hot air blower side, and the hot air flow rate is increased, and the warm air is injected into the inner tank 13. Since other configurations are the same as those in the first embodiment, the same reference numerals are used and description thereof will be omitted.

The operation in the above configuration will be described. In addition, since the operation | movement from washing process to dehydration process is the same as that of the said 1st Example, description is abbreviate | omitted.

In the drying stroke, the switching drainage cock 30 is opened, and the warm air is blown through the warm air supply passage 61 by the heating operation of the heater 25 and the blowing operation of the drying blower 26. It enters the inside of the inner tank 13 via the blower outlet 60, raises the temperature in the inner tank 13, and wash | cleans the laundry 35 by contacting the warm air and the laundry 35 by rotation of the pulsator 16. FIG. ). The warm air heats the laundry 35 to evaporate the water, and then is led to the connection duct 29 through a hole in the side of the inner jaw 13 or between the fluid balancer 15 and the inner partition plate 63. The exchange 31 is reached. In the heat exchanger 31, the warm air whose humidity has risen is cooled and dehumidified, and the dehumidified water is discharged from the drain hole 33. By the circulation of such warm air, the laundry 35 is dried. In the meantime, the pulsator 16 repeats the stirring of the laundry 35 while helping to dry it by carrying out reverse rotation to lift the laundry 35.

Here, since the jet port 60 is narrowly narrowed by the curved surface of which the flow path area was smooth, the warm air is injected into the inner tank 13 in a state where the cross-sectional area is narrow and the flow velocity is large with little pressure loss.

Then, it is strongly injected into the laundry 35 and spreads to the lower layer portion of the inner jaw 13 at a sufficient speed. Therefore, since heat and convection can be efficiently provided to the laundry 35, drying time can be shortened, drying nonuniformity can be reduced, and drying performance can be improved. Energy savings can be achieved because the drying time can be shortened.

In addition, in this embodiment, it is noted that the drying time and drying nonuniformity for determining the drying performance are closely related to each other, and in practice, it is not possible to clearly separate the respective causes and measures.

Next, a twelfth embodiment of the present invention will be described with reference to FIGS. 14 and 15.

As shown to FIG. 14 and FIG. 15, the inner partition board 65 is attached to the upper surface of the outer side chamber 14, and the cover 66 is attached to this inner partition board 65 so that opening and closing is possible. The lid 66 is located in front of the inner partition plate 65 and can be opened and closed with the axis supported by the inner partition plate 65 as a point. The sealing surface of the inner partition plate 65 and the lid 66 is provided with an airtight packing, and is provided with a latch or a magnet so as not to open suddenly from the closed position. When the hot air inlet 67 is formed in the inner partition plate 65, the hot air inlet 67 is disposed at the corner of the inner partition plate 65 so as to be completely separated from the cover 66 that can be opened and closed. The blower outlet 68 is connected directly to the warm air inlet 67, and is open toward the downward center direction of the inner side tank 13. As shown in FIG. The flexible tube 69 connects the hot air inlet 67 and the hot air supply passage 70. Since other configurations are the same as those of the eleventh embodiment, the same reference numerals are given and the description thereof will be omitted.

The operation in the above configuration will be described. In addition, since the operation | movement from washing process to dehydration process is the same as that of the said 1st Example, description is abbreviate | omitted.

In the drying stroke, the switching drain cock 30 is opened, and the warm air passes through the expandable tube 69 through the warm air supply passage 70 by the heat generation of the heater 25 and the blowing operation of the drying blower 26. The inside of the inner tank 13 through the jet port 68, and raises the temperature in the inner tank 13, and dry the laundry 35 by contacting the warm air and the laundry 35 by the rotation of the pulsator 16. Let's do it.

Here, from the washing stroke to the dehydration stroke and the drying stroke, the vibrator such as the outer jaw 14 vibrates because the pulsator 16 or the inner jaw 13 rotates. The suspension mechanism 19, the connection duct 29, the flexible tube 69, and the like absorb this vibration, but cannot fully absorb it, and are transmitted to the main body 20.

Therefore, the cover 66 which can be opened and closed is disposed in front of the inner partition plate 65, and the blower outlet 68 and the warm air inlet 67 are disposed at the corner side of the inner partition plate 65 and separated. Compared with the structure of 11th Example, since these structures located in the upper part of the outer side tank 14 can be made simple and lightweight, the generation | occurrence | production of the vibration of the outer side tank 14 in each stroke can be suppressed.

The lid 66 that can be opened and closed is most convenient to be opened and closed in a direction shown by a broken line, but may be other methods such as an accordion curtain type or a slide shutter type. In addition, the structure which opens and closes the inner partition board 65 without providing the cover 66 which can be opened and closed is difficult because an operation panel, an upper cover, etc. are comprised in the upper part of the main body 20 actually.

In addition, in the present embodiment as in the eleventh embodiment, it is noted that the drying time and the drying unevenness for determining the drying performance are closely related to each other, and in practice, it is not possible to clearly separate the respective causes and measures. Release.

Next, a thirteenth embodiment of the present invention will be described with reference to FIG.

As shown in FIG. 16, the drain cock 71 opens at the time of drainage, is formed in the lower part of the outer side tub 72, and is connected to the drain path 73. As shown in FIG. The overflow channel 74 is fixed to the outer side of the outer jaw 72, the upper end communicates with the overflow hole 75 formed inside the outer jaw 72, and the lower end is downstream from the drain cock 71. It is open so as to communicate with the drainage channel 73 of and is comprised so that the water overflowed from the predetermined | prescribed highest water level (water level to the overflow hole 75) in the outer tank 72 may be discharged | emitted from the drainage channel 73. As shown in FIG. In the drain passage 73, a trap 76 having a shape that causes water to accumulate on the way after joining the overflow channel 74 is formed, and drained through the trap 76, and at the same time, a pool of water by the trap 76. This prevents air leakage during drying. The duct 77 is elastic and connects an upper drainage passage from the drain cock 71 to the heat exchanger 31, and also through a hot air supply passage 70 having a heater 25 and a drying blower 26. It is comprised so that a warm air may blow out from the jet port 68 toward the downward center direction of the inner side tub 13 through the flexible tube 69. As shown in FIG. Here, the heater 25 and the drying blower 26 are arrange | positioned at the position higher than the overflow hole 75. As shown in FIG. Since other configurations are the same as those of the twelfth embodiment, the same reference numerals are used and the description thereof will be omitted.

The operation in the above configuration will be described. First, when the washing stroke is described, when the lid 66 which can be opened and closed is opened and the laundry 35 and the detergent are introduced into the inner tank 13 to start operation, a predetermined water level from the water supply valve into the inner tank 13 is started. After supplying water until the pulsator 16 is rotated, a washing stroke is performed. During the washing stroke, especially when the laundry 35 is large and the water level is high, the water exceeding the predetermined level of the water flows from the overflow hole 75 formed in the outer tank 72 to the overflow channel 74, the drainage path 73 and Drained via trap 76. At this time, the heat exchanger 31 is also filled with water through the duct 77 until it becomes at the same level as the inside of the outer tank 72. After the washing stroke, a rinsing stroke similar to the washing stroke is executed.

Next, the process proceeds to a dewatering stroke, and after opening the drain cock 71 to drain the water in the inner jaw 13, the normal operation of dewatering by rotating the inner jaw 13 at high speed is carried out to dry. Go to administration.

Next, the drain cock 71 is closed in the drying stroke. Then, the laundry adhering to the inner wall of the inner jaw 13 is removed by the centrifugal force of dewatering by rapidly rotating the pulsator 16 forward and backward. Thereafter, the warm air heated by the heater 25 is injected into the inner tank 13 from the jet port 68 by the drying blower 26. Then, the warm air heats the laundry 35 to evaporate water, and then a gap between the hole on the side of the inner jaw 13 or the gap between the fluid balancer 15 and the inner partition plate 65, the pulsator 16 and the inner jaw ( Through a gap or the like of 13, the lower portion of the outer jaw 72 is led to the duct 77 to reach the heat exchanger 31. The warm air whose humidity rises by evaporating the water | moisture content of the laundry 35 is cooled and dehumidified by the heat exchanger 31, and returns to the drying blower 26 again. In this way, drying is advanced, circulating and dehumidifying a warm air. The dehumidified water generated by heat exchange in the heat exchanger 31 gradually accumulates in the upper portion of the drain cock 71. For this reason, the drain cock 71 can be opened for several seconds at predetermined time intervals, and the dehumidifying water which is dehydrated can be drained, and the hot air flow path can be prevented from being blocked by the dehumidifying water. In the meantime, the pulsator 16 repeats stirring of the laundry 35 while carrying out forward and reverse rotation to lift the laundry 35, and helps drying. In addition, during the drying stroke, the drain cock 71 may be in an open state. However, although the warm air does not flow out to the outside by the trap 76, there is a possibility that the overflow channel 74 is bypassed and the warm air is bypassed and the drying performance is slightly reduced.

Here, when water blows into the terminal, wiring, internal circuit, etc., which are electric components, the drying blower 26 and the heater 25 have a risk of component breakdown, short circuit, and short circuit. However, since the drying blower 26 and the heater 25 are disposed at a position higher than the overflow hole 75, the water level does not reach the drying blower 26 and the heater 25 even during the washing and rinsing stroke. Therefore, safety can be ensured without invading water.

In addition, since the trap 76 is formed in the drain passage 73 after joining the overflow channel 74, the trap 76 can be drained without any problems and the overflow channel 74 or the open drain during the drying stroke. It is possible to prevent the warm air from flowing out of the cock 71 to the outside. In addition, since the heat exchanger 31 connected to the upper part of the drain cock 71 and the hot air supply path 70 are connected to each other by the flexible duct 77, the main body is connected by one drain cock 71. The warm air flow path between the (fixed side) 20 and the outer side jaw (vibration side) 72 can be secured by reducing the space.

In this embodiment, the flexible tube 69, the warm air supply path 70 and the like are configured in the same manner as in the twelfth embodiment, but may be configured in the same manner as in the first to eleventh embodiments.

Next, a fourteenth embodiment of the present invention will be described with reference to Figs.

As shown in FIG. 17, the water supply valve 78 is fixed to the main body 20 to supply tap water into the inner jaw 13 from the tap, thereby providing a water supply port 80 formed on the inner partition plate 79. It feeds into the inner jaw 13 through. The water supply duct 81 has elasticity and connects the water supply valve 78 and the water supply port 80 to form a water supply path. As shown in FIG. 18, two water supply paths are formed and correspond to the detergent inlet 82a and the softener inlet 82b of the detergent inlet container 82 formed in the water inlet 80, respectively.

The warm air supply passage 70 has a heater 25 for heating the warm air and a drying blower 26 for supplying the warm air into the inner tank 13 and is fixed to the main body 20. The hot air supply passage 70 is formed in communication with a jet port 68 via a bellows-shaped stretchable tube 69. The inner partition plate 79 is fixed to cover the upper surface of the outer jaw 14 to prevent leakage of the warm air upwards, and the cover 83 is supported on the inner partition plate 79 so as to be openable and closed. The 83 is opened to allow the laundry 35 to enter and exit. When the water supply port 80 and the jet port 68 are viewed from the user side, the water supply port 80 is disposed at the corner of the inner partition plate 79, thereby making the cover 83 openable and wider and making the water supply duct 81 compact. It consists.

Moreover, the heat exchanger 31 which performs cooling dehumidification is formed in the upstream of the warm air supply path 70, and this heat exchanger 31 has the elasticity of the connection duct 84, and the airflow which opens and closes an airflow path. It is connected to the lower part of the outer side tank 14 via the furnace opening / closing valve 85. As shown in FIG. The trap drainage path 86 branches at the lowest point of the connection duct 84 and has a shape that causes water to accumulate on the way, and drains the dehumidifying water of the heat exchanger 31 and prevents leakage of air. The drain cock 87 is opened at the time of washing drainage and dehydration.

Next, with reference to FIG. 19, the detailed structure around the water supply port 80 is demonstrated. Detergent injecting container 82 is formed in the upper side (it may be lower) of the inner partition board 79 so that extraction is possible, and the detergent and the softening agent put into this detergent injecting container 82 are mixed with water supply, and the inner tank 13 ) Is supplied into. The check valve 88 is a membrane-shaped valve that is elastic and easily opened only in one direction, and is opened in a funnel form by hydraulic pressure from above, and when the hydraulic pressure is lost, the membrane is contracted and closed. The shower nozzle 89 is formed at the tip of the water inlet 80 and passes through a plurality of small holes to inject shower-shaped water into the inner jaw 13. In addition, the shower nozzle 89 is detachable, and other nozzles capable of performing different types of water injection are also prepared as necessary. Since other configurations are the same as those of the twelfth embodiment, the same reference numerals are used and the description thereof will be omitted.

The operation in the above configuration will be described. First, when the washing stroke is described, the lid 83 which can be opened and closed is opened to put the laundry 35 into the inner jaw 13. When the detergent and the softening agent are introduced into the detergent injecting container 82 and start operation, the detergent injecting unit (from the water supply valve 78) is opened in the state where the opening / closing valve 85 is closed by the drain cock 87 and the air flow. Water supply to 82a). Here, the detergent is dissolved in water to form washing water, and the water is passed into the inner tank 13 through the check valve 88 and the shower nozzle 89 of the water supply port 80 to a predetermined level. Next, the power of the motor 21 is transmitted to the pulsator 16 via the washing shaft by the clutch built in the motor 21, and the laundry 35 is stirred and washed by rotating the pulsator 16.

During washing, especially when there is a lot of laundry and the water level is high, the foam of the detergent is directed from the water supply port 80 toward the water supply duct 81 and, in the worst case, may flow back to the water supply, but the check valve 88 prevents this. do. Moreover, although the overflow hole (not shown) is formed in the outer side tank 14 so that water may not overflow, even if it overflows, it will be prevented by the check valve 88, and the reverse flow to the worst case water can be avoided. have.

In the last rinsing stroke, the softener inlet 82b side of the water feed valve 78 is opened, and the softener is sprayed with water into the inner tank 13. After the washing and rinsing stroke is completed, the dehydration stroke is performed by draining the water in the inner jaw 13 by opening the drain cock 87 and then applying the power of the motor 21 to the inner jaw 13 by a clutch built in the motor 21. ), The inner jaw 13 is rotated together with the pulsator 16 to dehydrate the laundry 35 by centrifugal force.

Next, in the drying stroke, the pulsator 16 is rapidly rotated forward and backward to remove the laundry 35 stuck to the inner wall of the inner jaw 13 by centrifugal force in the dehydration stroke. And the drain cock 87 is closed and the open / close valve 85 is opened by airflow. Thereafter, the wind generated by the drying blower 26 is heated while passing through the heater 25 to become warm air, and is injected into the inner tank 13 from the jet port 68 through the flexible tube 69. . At this time, since the inner partition plate 79 is formed, the warm air does not run upward. After the laundry 35 is heated to evaporate water, the lower portion of the outer jaw 14 is disposed through a hole in the side surface of the inner jaw 13 or a gap between the fluid balancer 15 and the inner partition plate 79. Guided to the connecting duct 84 to reach the heat exchanger (31). The hot air of high humidity is cooled and dehumidified by the heat exchanger 31, and it returns to the drying blower 26 again. In this way, drying is advanced, circulating and dehumidifying a warm air. Dehumidifying water is discharged from the trap drainage path 86 to the outside. In the meantime, the pulsator 16 repeats stirring of the laundry 35 while carrying out forward and reverse rotation to lift the laundry 35, and helps drying.

Thus, the inner partition plate 79 which covers the upper part of the outer side tank 14 and prevents air leakage is formed, and the water supply valve 78 and the water supply port 80 formed in the inner partition plate 79 are connected. Since the water supply duct 81 is provided, water can be supplied through the water supply duct 81, and since the leakage of warm air can be prevented during the drying operation, the drying performance is excellent, and the room can be prevented from being wet. .

In addition, when the water supply port 80 is viewed from the user side, by disposing it on the corner side of the inner partition plate 79, the water supply path can be made compact and the input area of the laundry 35 can be secured widely. Therefore, the convenience of use can be improved in entering and leaving the laundry 35.

In addition, by forming the check valve 88 in the water supply port 80, it is possible to prevent backflow of bubbles and water to the water supply duct 81 during washing, and furthermore, to improve safety.

In addition, although the flexible tube 69, the warm air supply path 70, etc. are comprised similarly to the said 12th Example in this Example, you may comprise similarly to the said 1st Example.

In addition, in the present embodiment, the check valve 88 is configured to have an elastic membrane shape, but the present invention is not limited thereto, and the check valve 88 has a door shape which is opened only downward by the force of the fluid, or an electric control valve is used. You may also do it.

In addition, although the check valve 88 is arrange | positioned under the detergent injecting container 82, since foam may generate | occur | produce in the detergent injecting container 82, it is preferable to arrange | position upward.

In addition, although the shower nozzle 89 is comprised so that shower-shaped water injection may be performed to the inner side tank 13 through many small holes, it is not limited to this, A slit shape, sprinkler shape, etc. may be sufficient. In addition, examples of different types of water jets by different nozzles include high-speed jetting to entangle bubbles.
