Detailed description of the invention

[Technical Field]

The present invention relates to a laundry dryer which can continuously carry out washing, rinsing, and dehydration operations to a drying process.

[Background]

Conventionally, the thing of the structure as shown in FIG. 14 and FIG. 15 as a dryer is considered.

That is, the water tank 2 is rotatably supported by the horizontal shaft 3 in the main body 1 of the laundry dryer, and the rotation drum 4 is freely rotated through the rotation shaft 5 in the water tank 2. have.

In the lower part of the water tank 2, the pulsator, the drive converter 6 of the rotating drum 4, and the motor 7a which drives the rotating shaft 5 are formed. The rotary shaft 5 and the motor 7a are connected via a belt.

In the vicinity of the end of the horizontal shaft (3), the moving motor (7b) is fixed to the main body (1), the pinion gear (9) meshing with the worm gear (8) driven by the moving motor (7b) is a horizontal axis It is fixed to (3).

When the worm gear 8 rotates, the pinion gear 9 is driven. Accordingly, the horizontal shaft 3 rotates and the water tank 2 rotates with the horizontal shaft 3 as the rotation center.

In the lower outer side of the water tank 2, the fan 10 used at the time of drying is connected to the duct 12 through the heater 11, and the duct 12 is connected inward of the water tank 2; It is through. Reference numeral 13 is a drain.

The clothes are put in the water tank 2 of the washing machine having the above configuration, and the power is turned on.

Washing, rinsing, and dehydrating strokes are carried out with the water tank 2 in a vertical state as shown in the solid line of Fig. 14 and Fig. 15, and when the final dewatering stroke is completed, the next rotation of the moving motor 7b, that is, the worm gear The pinion gear 9 is driven by the rotation of (8), and the water tank 2 is brought into the horizontal posture to shift to the drying stroke.

This state is shown by the dashed-dotted line in FIG.

In this drying stroke, the rotary drum 4 is rotated and dried by energizing the fan 10 and the heater 11.

In the laundry dryer of the said structure, since the horizontal axis 3 which rotates the water tank 2 is installed in the front-back center of the main body 1 from the outer side of the water tank 2, the bottom area of the main body 1 becomes large, and this is conventionally In order to achieve the size of the washing machine capacity level, the water tank 2 must be made small, and thus the amount of clothes that can be washed and dried can be simplified.

In addition, the water tank 2 is supported by the horizontal axis 3 in order to rotate the water tank 2 so as to be approximately horizontal or approximately vertical, but the horizontal axis 3 is located on the side wall of the main body, and the drain hole 13 is located on the side wall. Since the trajectory of the drain port 13 is very large when the water tank 2 is rotated, the volume of the water tank 2 cannot be sufficiently secured in the main body 1 of limited size, and the washing and drying capacity is small. There is.

In addition, in order to effectively utilize the space in the main body 1, it is invented that the horizontal axis 3 is arrange | positioned at the corner part of the main body 1, but in this case, the upper part and the bottom part of the cylindrical water tank 2 are in this case. The trajectory at the time of rotation interferes with the side wall of the main body 1, and a problem arises that the volume of the water tank 2 cannot be fully secured.

In addition, in drying clothes, the drying air is heated and blown into the water tank 2, after which the damp drying air after drying the clothes is directly exhausted out of the machine. This frost has a problem.

On the other hand, it is conceivable to have a so-called dehumidification type clothes dryer having a heat exchanger and a circulation path for drying air. In the case of the laundry dryer, it is necessary to store water in the tank during washing, and water enters the circulation path. Therefore, there is a problem in that reliability and at the same time the circulation path itself is very complicated.

In addition, it is possible to operate only the drying stroke, not the drying after the dehydration stroke. If water remains in the tank at this time, the water is leaked out of the tank because the drying stroke is performed in the horizontal state, and there is a problem in reliability.

In addition, the amount of clothes that can be dried due to the volume of the rotating drum is about 1/2 of the amount of clothes that can be washed, rinsed, and dewatered. do.

Therefore, the user needs to determine whether to finish only by washing, rinsing, and dehydrating stroke or drying operation, depending on the amount of clothes at the start of washing, which is very inconvenient to use.

[Initiation of invention]

Therefore, it is a 1st object of this invention to make the rotating mechanism which can utilize the volume in a main body effectively.

A 2nd object is to comprise the drain and overflow drain which can utilize the volume in a main body effectively.

A third object is to construct a water tank that can effectively utilize the volume in the main body.

A fourth object is to obtain a drying mechanism having a high reliability and a simple configuration.

The fifth object is to obtain a high reliability that the water does not leak by any repayment.

The sixth object is to improve the convenience of use by detecting the quantity of clothing before drying administration and making an appropriate judgment as to whether drying is possible.

And in order to achieve the said 1st objective, in this invention, since the pair of rotating shafts which enable a water tank to be rotated was formed in the diagonal corner part of a main body, a rotating shaft is located in the corner part of a main body, and a water tank rotates. Even if it is possible to make the tank as large as possible, it is possible to effectively utilize the volume in the body.

In order to achieve the second object, the present invention provides a pair of rotary shafts in the diagonal corners of the main body, and when the water tank is in a substantially horizontal state, the drain hole is disposed at a position near the corner of the main body and overflows. Since the drain is formed near the corner of the main body when the water tank is approximately vertical, the trajectory of the drain and overflow drain during rotation passes through the corner of the main body, so that the volume in the main body can be effectively utilized, and the water tank is made larger. You can do it.

Further, in order to achieve the third object, the present invention provides a pair of rotary shafts at diagonal corners of the main body, and has a substantially cylindrical shape in which the top and bottom portions have a substantially cone shape. The trajectory becomes small and the tank can be enlarged.

Moreover, in order to achieve the 4th objective, since this invention forms the ventilation opening and the exhaust port from the water tank of the drying air for drying clothing, water invades a drying air passage. It is possible to realize a highly reliable laundry dryer with no short circuit or leak without a simple configuration.

Moreover, in order to achieve the 5th objective, this invention has the control apparatus which wash | cleans, rinses, and dehydrates a stroke in the substantially vertical state of a tank, and performs a drying stroke in the substantially horizontal state of a tank, Since the dewatering operation is performed before driving, even when water remains in the tank before rotation, the water is not leaked by dehydration in the tank, and high reliability can be obtained.

Further, in order to achieve the sixth object, the present invention has a quantity detecting means for detecting the amount of clothing before the drying operation, and when the quantity detecting means detects a predetermined amount of clothes, the control device Since the transition to the drying administration is stopped, the user does not need to determine whether the user can finish only the washing, rinsing, and dehydration stroke or even the drying administration, depending on the amount of clothing at the start of washing. It is very convenient.

The rotation reduction mechanism 52 is engaged with the worm wheel 57 provided with the worm mechanism 54 in the rotation reduction mechanism input shaft 53 and installed in the rotation reduction mechanism output shaft 56 with the winding pulley 55 attached thereto. It is configured to decelerate.

As shown in FIG. 8, one end of the wire 58 is fixed to the wire attachment member 59 attached to the bracket 41 of the motor, and the guide pulley A 60 and the guide pulley B attached to the main body A 14 are fixed. It rewinds to 61 and is wound by the winding pulley 55 fixed to the rotation reduction mechanism output shaft 56.

The rotation reduction mechanism 52 and the winding pulley 55 constitute rotational mounting. The guide pulley A 60 and the guide pulley B 61 move only a certain distance by the tension of the wire 58, and the spring A 62 and the spring return to their original positions when the tension of the wire 58 is lost, respectively. B 63 is provided.

It communicates with the duct 79.

By these structures, as shown in FIG. 9, the drying air path | route circulated from the blower 47 to the inside of the heat exchanger 48, the water tank A 18A, and the water tank B 18B is comprised. 80 is a control device, and controls the washing motor 33, the machine unit 27, the drying motor 36, the rotary motor 49, the heater 67 and the like. In addition, 81 is a quantity detection means connected to the control device 80. In this embodiment, when the washing motor 33 drives the pulsator 26 at the time of washing administration, the capacitor terminal voltage of the motor depends on the amount of clothes. I am using this change. That is, water is supplied to the low water level and the pulsator 26 is driven to measure the amount of clothes by measuring the condenser terminal voltage of the washing motor 33 at this time. After that, water is supplied later according to the quantity of clothes and washing is started.

Next, the operation in this first embodiment will be described.

The state of the water tank at the time of washing, a rinse, a dehydration stroke is shown in FIG. During washing, rinsing, and administration, the washing shaft 28 of the rotating drum 25 is positioned in a direction perpendicular to the installation surface of the main body A 14, wherein the pulsator 26 is interposed between the machine 27. It is connected to the washing shaft 28 and rotated by the washing motor 33 in a predetermined forward and backward cycle. At this time, the quantity detection means 81 determines the amount of clothing as described above. The amount of clothes which can be dried with a drum of the same size is about 1/2 of the amount of clothes which can be washed. When the amount of washable clothes is 4 kg, the amount of clothes that can be dried is 2 kg.

Thus, when the amount of clothing is detected to be more than a predetermined amount, that is, 2 kg or more, the control device 80 ends only with washing, rinsing, and dehydration strokes, and notifies the end of washing (steps 1 to 5 in FIG. 13).

If you want to dry, remove some clothes and dry. When the amount of laundry clothes is less than or equal to a predetermined amount, that is, less than or equal to 2 kg, the washing and rinsing and dehydration strokes are followed by a drying stroke to indicate the completion of drying (steps 4, 6 to 9 in FIG. 13).

During the washing operation, the tank is filled with water for washing. As shown in FIG. 5, the tank A (18A) and the tank B (18B) are fitted to each other, and the sealing material 19 is installed therebetween. Therefore, water does not leak out and is very reliable.

In the dehydration stroke, the rotating drum 25 is connected to the dehydration shaft 29 by the mechanical part 27 to rotate at a high speed of about 800 rpm to dewater. At this time, the vibration of the rotary drum 25 is transmitted from the water tank A 18A to the suspension 45 via the rotary shaft 43 and attenuated.

In the washing, rinsing, and dehydrating stroke, the reduction device 37 and the drying pulley 38 are disconnected by the clutch 39.

For this reason, the rotation of the washing motor 33 is not transmitted to the reduction gear 37 or the drying motor 36, and it does not interfere with the drive of the pulsator 26 or the rotating drum 25. FIG. In the case where there is a possibility that water remains in the water tank 18A, such as only drying, the dehydration operation is performed by the control device 80 before the water tank operation of the water tank when directly entering the drying stroke.

In this way, dehydration is performed when entering the rotational operation, thereby achieving high reliability without water in the tank and no leakage during rotation.

When the transition to the drying process is made, the residue detector 23 confirms that no water remains in the water tank A 18A, that is, when the resistance between the electrodes of the residue detector 23 exceeds a predetermined value. Rotate

Thereby, since it does not rotate in the state which remains in the water tank 18 in any situation, it becomes very reliable.

The rotation operation of the tank is connected by the rotation clutch 50, the rotation motor 49 is driven, and the winding pulley 55 attached to the rotation reduction mechanism output shaft 56 is wound around the wire 58, The tank slowly rotates about the rotation shaft 43. The rotary motor 49 is stopped by the water tank being horizontal and the limit switch B 65 is operated. The guide pulley A 61 moves by the tension of the wire 58, and releases the limit switch A 64.

In the rotation, as shown in Figs. 10 and 11, the rotating shaft 43 is formed at the corner portion of the main body A 14, so that the tank can be made as large as possible even when the tank is rotated. The volume in the body can be utilized effectively.

Moreover, since the bottom part and upper part of each tank A 18A and the tank B 18B are formed in a truncated cone shape, interference with the side wall of main body A 14 can be avoided, and the inside of main body A 14 is effective. It is possible to make use of it easily, so that the volume of the tank can be made as large as possible.

11 and 12, the drain port 22 is located in the motor portion of the main body A 14 when the water tank is horizontal, and the overflow drain 21 is a corner of the main body A 14. Since the trajectories of the drain outlet 22 and the overflow drain port 21 during rotation pass through the corners of the main body A 14, the volume in the main body A 14 can be effectively utilized. It is possible to increase the.

Subsequently, in the drying stroke, the rotary clutch 50 is released, and only the blower 47 is driven by the rotary motor 49.

At the same time, the drying motor 36 is driven, and the reduction device 37 and the drying pulley 38 are connected by the clutch 39.

The rotation of the drying motor 36 is decelerated to about 60 rpm by the reduction device 37 and at the same time the torque is amplified. For this reason, it is possible to obtain a large torque with a small motor and also to obtain a low speed rotation without the need for a complicated control device.

The rotating drum 25 starts to rotate by the drying motor 36 at a predetermined rotational speed of about 60 rpm via the belt B 40, thereby rotating the clothes inside the rotating drum 25.

The drying air heated by the heater 67 is blown from the tuyeres 68 into the water tank to dry the clothes.

After drying the clothes, the drying air having increased moisture passes through the exhaust port 73, passes through the lint filter 74, and is sent to the heat exchanger 48, and after being dehumidified, returns to the blower.

As such, the air dries the garment while circulating in the drying air path.

At this time, the cooling water for water cooling of the heat exchange is timely supplied from the tap water.

Since the heater 67 and the blower 68 and the exhaust port 73 to the water tank are installed in the upper portion of the water tank, the water of the heater 67 does not splash and no water penetrates into the drying air path. It is possible to obtain high reliability and high reliability without leakage or leakage, and the drying air after heating is immediately blown into the rotating drum 25 so that drying can be performed very efficiently.

Next, when the drying stroke is completed, the rotary drum 25 stops, and the rotary clutch 50 is connected, and the rotary motor 49 reversely rotates to release the wire 58 wound around the winding pulley 55.

When the water tank 18 is vertical, the tension of the wire 58 is weakened and the guide pulley A 60 is returned to the original position by the spring A 62 and the limit switch A 64 is operated to rotate the motor. (49) stops.

As described above, a series of steps is performed from washing to drying.

In addition, in the present invention, a pair of rotary shafts are installed at diagonal corners of the main body, and when the water tank is in a substantially horizontal state, the drainage outlet is disposed at a position near the corner of the main body, and the overflow drain is formed near the corner of the main body. As a result, the trajectories of the drain and overflow drains during rotation pass through the corners of the main body, whereby the volume in the main body can be effectively utilized and the water tank can be enlarged.

In the present invention, the pair of rotary shafts are provided at diagonal corners of the main body, and the tank is formed in a substantially cylindrical shape having a top and a bottom portion in a substantially conical shape. You can do it.

In addition, in the present invention, since the intake port of the air inlet to the water tank is provided in the upper portion of the water tank, water does not splash on the heater, and water does not intrude into the circulation air flow path, so that there is no fear of leakage or leakage. This high reliability is obtained.

Moreover, since this invention has the control apparatus which wash | cleans, rinses, and dehydrates a stroke in the substantially vertical state of a tank, and performs a drying stroke in the substantially horizontal state of a tank, dehydration operation | moves before drive of a rotating apparatus by a control apparatus.

In addition, the present invention has a quantity detecting means for detecting the amount of clothes before the drying operation, and when the quantity detecting means detects a predetermined amount of clothes or more, the transition to the drying administration is stopped by the control device. The amount of clothes can be detected until the start of the stroke, and the user does not need to determine whether to finish only the washing, rinsing, and dehydrating strokes or to the drying administration, depending on the amount of clothes at the start of washing. Will be.
