Description

    The present invention relates to a drum-type washing and drying machine provided with means for drying clothes.

  Drying clothes with a drum-type washer / dryer that can be used continuously from washing to drying creates high-temperature and low-humidity air (warm air) with a blower fan and a heat source, and blows it into the washing tub to control the temperature of the clothes. This is done by evaporating the moisture from the clothing and discharging the evaporated moisture out of the machine. There are two methods for removing the evaporated water: an exhaust system that discharges it directly outside the washing and drying machine (always supplying new air) and a dehumidification system that cools the evaporated water and condenses it to remove the water (circulates the same air). However, for home use, a dehumidification system that does not allow moisture to enter the room where the washing and drying machine is installed is often used.

  In order to shorten the drying time and reduce the power consumption, there are methods of increasing the amount of hot air or increasing the temperature of the hot air. A general drum-type washer / dryer for clothing is configured such that warm air is blown onto clothing from one direction of the rotating drum that houses the clothing (described here on the front side) and warm air is discharged from the opposite direction. ing. Recently, a drum-type washing machine in which the angle of the rotation center axis of the rotary drum is inclined so that the clothes outlet side (front side) is high and the rear side is low has been dominant. This type of drum-type washing and drying machine has an advantage that workability is improved and the amount of water used during washing can be reduced by raising the clothes take-out side.

  However, in the case of an inclined rotating drum, clothes such as cotton underwear and thick clothing are heavy, and often gather in the back of the rotating drum due to the influence of gravity over time. Since the warm air is blown from the front side of the rotating drum, it is difficult for the warm air to reach the clothing on the inner side of the rotating drum. For this reason, it is difficult for hot air to hit underwear and thick clothing, and thus there is a problem that uneven drying occurs and power consumption increases in order to dry these clothing.

  Therefore, as a drum-type washing / drying machine with a variable inclination angle of the rotating drum, there is a publication of JP-A-2005-34170. This drum type washing and drying machine has a rotating drum angle changing means so that the rotating drum operates horizontally during washing and drying, and the rotating drum is inclined when clothes are put in and taken out. For this reason, there is little collection of heavy clothing on the back side of the rotating drum during drying, and drying with little unevenness in drying can be realized.

JP 2005-34170 A

  However, since the rotating drum is horizontal during washing and drying, the amount of water used during washing cannot be reduced.

  An object of the present invention is to provide a drum-type washing and drying machine that saves water during washing, prevents uneven drying of clothes, and reduces power consumption for drying.

In order to achieve the above object, the present invention is characterized by:
A rotating drum for storing clothing; a motor for driving the rotating drum; an outer tub for storing the rotating drum; a housing for supporting the outer tub; and means for blowing warm air into the rotating drum ; A tilt angle variable mechanism for providing a suspension for vibration-proofing and supporting the lower side of the outer tub , wherein the rotation center axis of the rotary drum is tilted with respect to a horizontal direction, and the tilt angle of the rotation center axis of the rotary drum is changed. A drum-type washing / drying machine for washing, dehydrating and drying clothes in the rotating drum, wherein the tilt angle variable mechanism has a push rod movable in the front-rear direction, and a drive unit for driving the push rod; During the drying operation, the upper part of the outer tub is moved forward by pushing the displacement transmitting member fixed to the upper part of the outer tub with the push rod, while the washing and dehydrating are performed. At the time of rolling, the push rod is retracted to a position spaced apart from the displacement transmission member, so that the inclination angle with respect to the horizontal direction of the rotation center axis of the rotating drum at the time of the drying operation is set at the time of the washing and dehydrating operation. Inclination of the rotating drum so that the inclination angle of the rotation center axis of the rotating drum is smaller than the inclination angle of the rotation center axis of the rotating drum with respect to the horizontal direction, and when the drying operation is temporarily stopped, Change the angle .

  The drum type washing / drying machine constructed in this way can reduce the amount of water used during washing because the angle of inclination of the rotating drum is large during washing, and the clothes rotate because the angle of inclination of the rotating drum is smaller than during washing during drying. It is easy to change in the drum, and since the warm air uniformly hits the clothing and can reduce the occurrence of uneven drying, the dry power consumption can be reduced. Furthermore, the dry finish is also improved.

  In addition, when pausing during drying, the tilt angle of the rotating drum returns to its original value (the angle of the rotating shaft with respect to the horizontal direction of the rotating drum increases) and the opening of the rotating drum comes to oppose the door. It becomes easy to insert clothing on the way.

Further, the upper side of the outer tub 2 is supported by auxiliary springs 11a and 11b attached to the upper reinforcing member 1j to prevent the outer tub 2 from falling in the front-rear direction.

  Reference numeral 19 denotes a detergent container provided on the upper left side in the housing 1, and a drawer-type detergent tray 7 is mounted from the front opening. When putting detergents, the detergent tray 7 is pulled out as shown by a two-dot chain line in FIG. The detergent container 19 is fixed to the upper reinforcement 1j of the housing 1.

  On the back side of the detergent container 19, components related to water supply such as a water supply electromagnetic valve 16, a bath water supply pump 17, and a water level sensor (not shown) are provided. The top cover 1e is provided with a water supply hose connection port 16a from a water tap and a water absorption hose connection port 17a for remaining hot water in the bath. The detergent container 19 is connected to the outer tub 2 and supplies washing water to the outer tub 2 by opening the water supply electromagnetic valve 16 or operating the bath water supply pump 17.

  Reference numeral 29 denotes a drying duct installed vertically inside the back surface of the housing 1, and a lower portion of the duct is connected to an intake port 2 a provided below the back surface of the outer tub 2 by a rubber bellows tube B 29 a. The drying duct 29 has a built-in water-cooled dehumidifying mechanism (not shown). The cooling water hose 24 connects the water supply electromagnetic valve 16 and the water-cooling dehumidifying mechanism, and opens the water supply electromagnetic valve to cool the water-cooled dehumidifying mechanism. Supply water. The cooling water flows down along the wall surface of the drying duct 29, enters the outer tub 2 through the intake port 2a, and is discharged from the drain port 2b.

  The upper part of the drying duct 29 is connected to a filter duct 27 installed in the front-rear direction on the upper right side in the housing 1. The filter duct 27 has an opening on the front surface, and a drawer-type drying filter 8 is inserted into the opening. The air that has entered the filter duct 27 from the drying duct 29 flows into the mesh filter 8a of the drying filter 8, and lint is removed. Cleaning of the dry filter 8 is performed by pulling out the dry filter 8 and taking out the mesh filter 8a. In addition, an opening is provided on the lower surface of the insertion portion of the filter 9 in the filter duct 27, and the opening is connected to the intake duct 33, and the other end of the intake duct 33 is connected to the intake port of the blower unit 28. doing.

  The blower unit 28 includes a drive motor 28a, a fan impeller (not shown), and a fan case 28b. The fan case 28b incorporates a heater 31 and heats air sent from the fan impeller. The heater 31 can be switched between inputs, and the heater of this embodiment has a strong mode and a weak mode. The discharge port of the blower unit 28 is connected to the hot air duct 30. The hot air duct 30 is connected to a hot air outlet 32 provided in the outer tank cover 2d through a rubber bellows tube A30a and a bellows tube joint 30b.

  In the present embodiment, since the blower unit 28 is provided on the upper right side in the housing 1, the hot air outlet 32 is provided at a position diagonally above and to the right of the outer tank cover 2d, and the distance to the hot air outlet 32 is set. It is made as short as possible to minimize pressure loss and heat escape.

  Temperature sensors (not shown) are provided at the outlet 2b and the inlet and outlet of the blower unit 28.

  The flow of wind during the drying operation is indicated by solid line arrows and broken line arrows in FIGS. When the blower unit 28 is operated and the heater 31 is energized, warm air blows into the washing and dewatering tub 3 from the warm air outlet 32 (arrow 41), hits the wet clothing, warms the clothing, and evaporates moisture from the clothing. The air that has become hot and humid flows from the through hole provided in the washing and dewatering tub 3 to the outer tub 2 and is sucked into the drying duct 29 from the air inlet 2a and flows from the bottom to the top in the drying duct 29 (arrow 42). Cooling water from the water cooling and dehumidifying mechanism flows down on the wall surface of the drying duct 29, and the hot and humid air is cooled and dehumidified by contacting with the cooling water, and becomes dry low temperature air and enters the filter duct 27 (arrow 43). . The lint is removed through the mesh filter 8a provided in the filter duct 27, enters the intake duct 33, and is sucked into the blower unit 28 (arrow 44). Then, it is heated again by the heater 31 and circulates so as to blow into the washing and dewatering tub 3. During this time, the washing and dewatering tub 3 is rotated forward and backward at a low speed to lift the garment to the vicinity of the warm air outlet 32 so that the warm air efficiently strikes the garment.

  A feature of the present invention is that the inclination angle of the rotation central axis of the washing and dewatering tub 3 is made smaller during drying than during washing, and uneven drying is reduced. An example of a tilt angle variable mechanism that changes the tilt angle of the washing and dewatering tub 3 will be described with reference to FIGS. 5 and 6. FIG. 6 is a cross-sectional view of the drum-type washing / drying machine cut in the vertical direction at the approximate center in the left-right direction. The movement of the tilt angle variable mechanism, the outer tub 2 and the washing / dehydration tub 3 and the movement of clothing during drying are shown. Show. Reference numeral 60 denotes a tilt angle variable mechanism, which is attached to the lower surface of the upper reinforcing member 1j, and includes a push rod 61 that is movable in the front-rear direction and a drive unit 62 that drives the push rod 61. Reference numeral 63 denotes an L-shaped displacement transmission member fixed to the upper portion of the outer tub 2 and transmits the movement of the push rod 61 to the outer tub.

  The outer tub 2 is supported on the lower side by an anti-vibration suspension 5 and operates in the vertical direction, but hardly moves in the front-rear direction. The upper side is supported by auxiliary springs 11a and 11b attached to the upper reinforcing member 1j, and prevents the outer tub 2 from falling in the front-rear direction. By pushing the displacement transmitting member 63 with the push rod 61, the upper side of the outer tub 2 moves forward (at this time, the auxiliary spring 11a extends and the auxiliary spring 11b contracts), but the lower side of the outer tub is the suspension 5 in the front-rear direction. Since it is difficult to move, the inclination angle of the outer tub becomes small as shown by a two-dot chain line in the figure. Since the outer tub 2 and the washing / dehydrating tub 3 are arranged on the same axis, the inclination angle of the washing / dehydrating tub 3 is also reduced.

  At the time of washing (washing, rinsing, dehydration), the push rod 61 is in a position retracted to a position separated from the displacement transmission member 63 by a sufficient distance. This is to prevent the tilt angle variable mechanism 60 from being damaged by the vibration of the outer tub 3 during washing. At the time of drying, the push rod 61 is in the advanced position, and the inclination angles of the outer tub 2 and the washing / dehydrating tub 3 are reduced (indicated by a one-dot chain line in FIG. 6).

  The movement of the clothes in the front-rear direction when the drying operation is performed while the inclination angle of the washing / dehydrating tub 3 at the time of washing (the angle of the rotation axis of the washing / dehydrating tub with respect to the horizontal direction) is indicated by a solid arrow 65 in the figure. . When the washing and dewatering tub 3 rotates, the clothes are lifted along the outer peripheral wall by the lifter 3b and centrifugal force, and fall almost vertically by gravity, so that the clothes fall to the back side from the initial position. When this is repeated, the clothing gradually moves to the back side of the washing and dewatering tank 3. In ordinary households, the clothes to be washed are usually a mixture of cotton and cotton / synthetic fiber. Cotton clothes (especially underwear and thick ones) are more profound. Easy to move to the side. For this reason, it is easy for dry clothes, such as blended clothes and cotton, which are easy to dry, to gather on the front side of the washing and dehydrating tank 3 and cotton clothes which are difficult to dry on the back side. Since warm air is blown out from the front side of the washing / dehydrating tub 3, cotton clothes that are difficult to dry become more difficult to dry, resulting in uneven drying and increased power consumption for drying to dry clothes that are difficult to dry. ing. Actually, the clothes that have gone to the back side move slowly to the front side again, by adjusting the shape of the lifter 3b or adjusting the left and right rotation times of the washing and dewatering tub 3. However, the frequency of changing clothes in the front-rear direction in the washing and dewatering tank 3 is smaller as the inclination angle is larger.

  Therefore, by making the inclination angle of the washing and dewatering tub 3 at the time of drying smaller than that at the time of washing, the movement of the garment becomes as shown by a one-dot chain line arrow 64 in FIG. 6, and the amount of movement to the back side is small. , Cotton clothes will be difficult to go to the back side. The frequency of changing clothes in the front-rear direction in the washing and dewatering tub 3 is increased, the occurrence of uneven drying can be reduced, and wasteful power consumption can be suppressed.

  FIG. 7 shows a drum-type washing / drying machine having a drying capacity of 6 kg (the washing and dewatering tank 3 has an inner diameter of 610 mm and a volume of 82 L) when drying 4 kg of clothing (material ratio: 65% cotton, 35% synthetic fiber blend). It is an example of the experimental result which investigated the standard deviation (drying unevenness) of the dryness of the cotton clothing which tends to become a drum inclination angle and dryness, and dry unevenness. The experiment was performed with the same amount of power consumption during drying. The higher the dryness, the better the drying performance. The dryness is defined as the mass of dry clothing / the mass of clothing after drying. The mass of dry clothing is the mass when clothing is left overnight in an environment of temperature 20 ° C. and relative humidity 65%. The dryness of a completely dried garment is 108.0% for cotton and 100.4% for polyester.

  As is clear from the experimental results, it can be seen that the smaller the inclination angle of the washing and dewatering tub 3, the higher the dryness and the smaller the unevenness of drying. In other words, the dry power consumption required to obtain the same dryness can be reduced as the inclination angle is smaller. This is because, as described above, the smaller the tilt angle of the drum, the better the replacement of clothes in the washing and dewatering tub 3 and the warm air uniformly hits the clothes. Uniform application of warm air to clothing also has the effect of improving the finish of clothing (reducing wrinkles) when the wind speed of the warm air is high enough to stretch the wrinkles of the clothing.

  On the other hand, FIG. 8 shows the relationship between the inclination angle of the washing and dewatering tub, the amount of water used during washing, the cleaning power, and the washing unevenness. Detergency and unevenness are shown as relative values based on an inclination angle of 10 degrees. The amount of water used decreases as the inclination angle of the rinsing and dewatering tank 3 increases. In the drum type washer / dryer used in this experiment, the amount of water used increased by about 1 L when the inclination angle decreased by 1 degree. The detergency starts to decrease sharply when the inclination angle exceeds 10 degrees, and the washing unevenness starts to increase rapidly when the inclination angle exceeds 10 degrees. From this, it can be seen from the detergency and the amount of water used that the inclination angle of the washing and dewatering tub is preferably about 10 degrees during washing. On the other hand, as described above, it is better to make the inclination angle as small as possible for drying.

  From the above, by setting the inclination angle of the washing and dewatering tub to about 10 degrees during washing and making the inclination angle smaller than during washing, high washing power during washing, water saving, and reduction in power consumption during drying can be realized.

  FIG. 9 is a block diagram of the control device 38 of the washing / drying machine. A microcomputer 50 is connected to the operation button input circuit 51, the water level sensor 34, and the temperature sensor 52 connected to the switches 12, 13, 13a, and various information signals in the user's button operation, washing process, and drying process. Receive. The output from the microcomputer 50 is connected to the drive circuit 54 and connected to the water supply electromagnetic valve 16, the drain valve 25, the motor 4, the blower fan 28, the heater 31, the tilt angle variable mechanism drive unit 62, etc. Controls rotation and energization. Further, it is connected to a 7-segment light-emitting diode display 14, a light-emitting diode 56 and a buzzer 57 for notifying the user of the operating state of the washing machine.

The temperature of the entire clothing rises and moisture evaporates from the clothing. At this time, although the push rod 61 and the displacement transmission member 63 are in contact with each other, the forward / reverse rotation of the washing / dehydrating tub 3 is about 40 to 50 rotations per minute, and the washing / dehydrating tub 3 has less vibration, No extra force is applied to the push rod 61.

Step S110
It is determined whether or not there is a request for temporary stop of the drying operation by operating the operation panel 6. When there is no request for temporary stop, the process proceeds to step S112 and the drying operation is continued. If there is a request for suspension, the process proceeds to step S111. The contents of step S111 will be described later with reference to FIG.

Step S112

At this time, it is displayed that the inclination angles of the outer tub 2 and the washing / dehydrating tub 3 of the display device 14 are being changed.

Step S114
The display of the inclination angle of the outer tub 2 and the washing and dewatering tub 3 on the display 14 is stopped, and the operation is ended (step S115).

Step S204
The inclination angle of the washing and dewatering tub 3 is displayed on the display 14. At the same time, the user is notified that the washing and dewatering tub 3 is changing the inclination angle. Since the door 9 is still locked while the inclination angle of the washing / dehydrating tub 3 is being changed, the user is not misunderstood as a malfunction by giving such notification.

Step S205
The display 14 displays that it is temporarily stopped.

Step S206
It is determined whether or not cancellation of the pause has been requested by the user's operation on the operation panel 6. If there is a request for canceling the suspension, the cancellation is executed and the process proceeds to step S207. If there is no request, the process returns to step S205.

Step S207
Since the suspension cancellation has been executed, the suspension display is canceled.

Step S210
Perform the drying operation again. The blower unit 28 is rotated, the heater 31 is energized, the forward / reverse rotation of the washing / dehydrating tub 3 is repeated, and hot air is blown onto the garment while changing the position of the garment in the washing / dehydrating tub 3. Then, the temporary stop process is terminated (step S211).

The inclination angle at the time of drying is made smaller than the inclination angle of the rotating drum.

  The drum type washing / drying machine constructed in this way can reduce the amount of water used during washing because the angle of inclination of the rotating drum is large during washing, and the clothes rotate because the angle of inclination of the rotating drum is smaller than during washing during drying. It is easy to change in the drum, prevents clothes from clumping, and high-speed warm air can evenly strike the clothes to reduce the occurrence of uneven drying, thus reducing drying power consumption. Furthermore, wrinkles can be prevented by applying high-speed warm air evenly to clothing, and the drying finish can be improved.

  Further, according to the above embodiment, when the suspension is temporarily stopped during the drying, the inclination angle of the rotating drum is restored (the angle of the rotating shaft with respect to the horizontal direction of the rotating drum is increased), and the opening of the rotating drum is connected to the door. Since it comes to oppose, it becomes easy to insert clothing on the way.

  Further, according to the above embodiment, since the operation is displayed (notified) when the tilt angle of the rotating drum is changed, it is possible to notify the user that the rotating drum is moving. Further, since the door is locked while the tilt angle of the rotating drum is being changed, the user is not misunderstood as a malfunction by giving such notification.
