FIG. 3 (a) is a cross-sectional view of the hot air supply port of the washing / drying machine closed, and FIG. 3 (b) is an open hot air supply port of the washing / drying machine. FIG.

  In FIGS. 2A, 2 B, 3 A, 3 B, the hot air supply port 20 having the opening 55 is provided at the lower end of the upper bellows-like hose 18, and the hot air supply port 20 is The four guide plates 57 supported by a shaft 53 substantially perpendicular to the hot air ejection direction are provided in parallel openably and closably.

  The guide plate 57 forms locking portions 58 at both end portions on the upper surface side in the longitudinal direction in the horizontal state, that is, at both end portions on the upstream side of the hot air circulation path 17.

  The locking portion 58 is formed on one side in the opposite longitudinal direction with its end 58 a protruding beyond the upper surface of the guide plate 57, whereby the guide plate 57 is biased against the shaft 53. . When the guide plate 57 is in the closed state, it abuts on the upper surface of the adjacent guide plate 57. At this time, the end 58 a is formed to be located above the shaft 53 of the adjacent guide plate 57. In the guide plate 57 at the end of the four guide plates 57, and the guide plate 57 at the left end in FIG. 3A, the end 58a of the locking portion 58 in the closed state is the inner periphery of the warm air supply port 20. On the side, it contacts with one side of one of the guide plate receiving portions 59 formed substantially horizontally on the outside of the four guide plates 57 from above.

  The operation and action of the washing and drying machine configured as described above will be described below.

  In the washing process, the lid 49 and the inner lid 21 are opened, and clothes (washing) are put into the inner tub 4 to start operation. After the water supply valve 32 is opened and water is supplied to a predetermined water level, the motor 8 is driven. Do. At this time, the motive power of the motor 8 is transmitted to the rotary wings 6 via the washing / dewatering shaft 5 by the clutch 9 of the transmission mechanism portion, and the rotary wings 6 are rotated to stir and wash the clothes in water. Thereafter, the drainage valve 22 is opened and drained, and in the rinsing step, water is again supplied and the clothes are rinsed in the same operation as the washing step.

In the dewatering process, after completion of the rinse, the drainage valve 22 is opened to drain the water in the inner tank 4, and then the clutch 9 of the transmission mechanism is switched to the dewatering side to motive power of the motor 8. Water is transmitted from the inner tub 4 through the dewatering shaft and rotated, and centrifugal force is applied to the garment to separate moisture from the garment.

  In the process up to here, the four guide plates 57 have an offset load around the shaft 53, and the locking portion 58 side is heavy, so in FIG. 3A, it rotates counterclockwise around the shaft 53. However, since the end portion 58a is positioned up to the upper side of the shaft 53 of the adjacent guide plate 57, the end portion 58a is held substantially horizontal. The end 58 a of the guide plate 57 at the end abuts on the guide plate receiving portion 59. That is, the hot air supply port 20 is closed by the four guide plates 57. When the dewatering process is completed, the process proceeds to the drying process.

  In the drying process, the motor 8 is driven to transmit to the rotary blade 6, and the rotary blade 6 is rotated slowly to peel off the clothes stuck to the inner wall of the inner tank 4 by the centrifugal force at the time of dewatering. A tank rotation drying process is performed to dry the clothes while rotating the inner tank 4 at a low speed for a predetermined time.

  Furthermore, after that, the rotor blade 6 is momentarily strongly rotated in the forward and reverse directions, and the clothes are thrown up in the inner tank 4 to perform a stirring and drying process of drying while stirring.

  At the same time, by driving the hot air blowing means 28, the air taken in from the outer tank 3 through the heat exchange duct 12 and the like becomes the hot air heated through the heater 16, and the hot air supply port 20 It is more likely to be fed into the inner tank 4.

  At this time, warm air pushes the guide plate 57 of the warm air supply port 20, but the guide plate 57 pushed by the warm air rotates clockwise around the shaft 53 in FIG. 3B. Thus, the hot air supply port 20 is opened, and the hot air is blown out toward the inner tank 4 along the guide plate 57.

  In addition, since the inclination by the rotation of the guide plate 57 does not go beyond the spouting direction of the warm air, the substantially vertical direction is the limit at the time of opening. Therefore, the inclined range of the guide plate 57 is located between horizontal and vertical, that is, 0 to 90 °. That is, by controlling the amount of warm air, the angle of the guide plate 57 can be adjusted between 0 and 90 °.

  That is, the control means (not shown) controls the number of rotations of the blower fan motor (not shown) of the hot air blower 28 as needed, such as the amount of clothes and the dry state, and the blower fan 15 By adjusting the volume of the supplied warm air, the direction of the warm air blown out along the guide plate 57 is changed.

  The warm air blown into the inner tank 4 from the hot air supply port 20 evaporates the moisture from the clothes and then passes through the drainage path port 14 provided in the lower part of the outer tank 3, the connection duct 13, and the heat exchange duct 12. When the air conditioner is in operation, the naturally cooled warm air is dehumidified, enters the circulating air receiving chamber 45, passes through the filter 46, and then returns to the blower fan 15. The clothes in the inner tank 4 can be dried by circulating warm air in this circulation path.

  As described above, in the first embodiment, the hot air supply port 20 is provided with a plurality of guide plates 57 supported by the shaft 53 substantially perpendicular to the hot air ejection direction in a freely open / close manner. With the configuration to be formed, the openable / closable guide plate 57 is in the closed state when not necessary, and the spray or foam generated by the washing does not intrude from the hot air supply port 20, and Because it can be opened only and hot air can be blown out, reliability can be improved and quality can be improved.

Further, the guide plate 57 forms locking portions at both end portions on the upper surface side in the longitudinal direction in the horizontal state, and the locking portion 58 protrudes one end portion 58 a in the anti-longitudinal direction from the upper surface of the guide plate 57 When the guide plate 57 is in the closed state, the end 58a is positioned above the shaft 53 of the adjacent guide plate 57 and abuts against the upper surface, whereby the openable / closable guide plate 57 is not required. Because it can be closed reliably, splashes and bubbles generated during washing do not enter from the hot air supply port 20, and it can be opened only in the drying process to blow out warm air, thus improving reliability. Can improve the quality.

  Further, by controlling the number of rotations of the blower fan motor of the warm air blowing means 28 and adjusting the volume of the supplied warm air, the direction of the warm air spouted along the guide plate 57 can be varied. Thus, the drying efficiency can be improved because the drying air can be made more optimal as needed depending on the amount of clothes, the dry state, and the like.

Second Embodiment
Fig.4 (a) is the perspective view seen from the bottom of the warm air supply port of the washing / drying machine in the 2nd embodiment of the present invention, FIG.4 (b) is the upper direction at the time of closing the same warm air supply port. FIG. 5 (a) is a plan view from above when the warm air supply port is opened, and FIG. 5 (b) is a cross-sectional view when the warm air supply port is open. The configuration other than the configuration of the hot air supply port is the same as that of the first embodiment, and the description will be omitted.

  In FIGS. 4A, 4B, 5A, and 5B, the hot air supply port 40 having the opening 65 at the lower end of the upper bellows-like hose 18 is loosely fitted, and the hot air supply is performed. The mouth 40 is rotatable horizontally.

  In the hot air supply port 40, a slender support 61 which divides the opening 65 into two parts is in the central part, and three of the guide plates 67 supported by the shaft 63 substantially perpendicular to the hot air ejection direction. The three sheets are provided in parallel on the half side of the opening 65 so as to be openable and closable, and three guide plates B62 similarly supported by the shaft 63 are provided so as to be openable and closable in parallel on the other half side of the opening 65 There is. Flat portions 69 are integrally formed with the support 61 on both sides in the opposite longitudinal direction of the guide plate 67 and the guide plate B 62, and when the guide plate 67 and the guide plate B 62 are closed, they are combined with the flat portion 69 and the support 61, The entire opening 65 is closed.

  Further, in the guide plate 67 and the guide plate B62, the locking portion 68 is formed on the upper surface portion on the side of the support column 61 which is the longitudinal direction, whereby the guide plate 67 and the guide plate B62 are biased around the shaft 63. It has become. The guide plate 67 and the guide plate B 62 are rotationally symmetrical by 180 ° in a state where the locking portion 68 is formed.

  The locking portion 68 is formed such that the end portion 68a protrudes from the upper surface of the guide plate 67 and the guide plate B 62 toward the support 61 side in an L shape, and the guide plate 67 is anti-opened in FIG. 5B. The guide plate B62 contacts the upper surface of the support 61 when it is closed by rotating clockwise about the shaft 63, and the guide plate B62 rotates clockwise about the shaft 63 from the open condition in FIG. When it comes to contact, it comes in contact with the upper surface of the support 61.

  The operation and action of the washing and drying machine configured as described above will be described below.

  When warm air including washing is stopped, the guide plate 67 and the guide plate B 62 are lowered on the side of the locking portion 68 which is heavy with a partial load centering on the shaft 63 and the locking portion 68 is on the upper surface of the support 61 The hot air supply port 40 is closed by a total of six guide plates 67 and a guide plate B 62 because they abut and stay in a horizontal state.

In the drying process, by driving the hot air blowing means 28, the air taken in from the outer tank 3 through the heat exchange duct 12 and the like becomes the hot air heated through the heater 16, and the hot air is supplied. When it is attempted to feed the inside of the inner tank 4 from the port 40, the hot air pushes the guide plate 67 and the guide plate B62 provided in the air duct 29. Then, the guide plate 67 and the guide plate B 62 rotate around the shaft 63, the hot air supply port 40 is opened, and the hot air flows through the guide plate 67 and the guide plate B6.
It spouts out toward the inner tank 4 along 2.

  At this time, since the inclination angles of the guide plate 67 and the guide plate B 62 can be varied from 0 to 90 ° depending on the amount of warm air, if the inclination angle is larger than 0 and smaller than 90 °, When changing the direction of the hot air, a force perpendicular to the guide surface acts.

  And since the guide plate 67 and the guide plate B 62 are provided in the left-right reverse direction, the lateral component force of the force acting on this surface is the reverse direction with the support column 61 as the boundary. Therefore, a rotational force acts on the hot air supply port 40, and the warm air supply port 40 is freely fitted to the lower end portion of the upper bellows-like hose 18 and is rotatable, so the rotational force holds the hot air supply port 40. The hot air supply port 40 starts to rotate when it overcomes the frictional force.

  Therefore, since the hot air is spouted while the hot air supply port 40 rotates, the rotational flow of the hot air can be generated in the inner tank 4 and the hot air can be applied to all directions of the inner tank 4 without bias. Uneven drying can be prevented.

  As described above, in the second embodiment, the hot air supply port 40 is freely loosely fitted in the lower end portion of the upper bellows-like hose 18 in a horizontal state so as to divide the opening 65 into two. A plurality of guide plates 67 and guide plates B62 provided at 180 ° rotational symmetry on both sides of the elongated column 61 formed at the central portion, the guide plate 67 and the guide plate B62 are on the side of the column 61 which is the longitudinal direction The L-shaped locking portion 68 is formed on the upper surface portion of the lock portion 68, and when the guide plate 67 and the guide plate B 62 are closed, the end portion 68a of the locking portion 68 is in contact with the upper surface of the support 61 Thus, the guide plate 67 and the guide plate B62 which can be opened and closed can be closed reliably when they are not needed, so that sprays and foams generated by washing do not enter from the hot air supply port 40, and Open only and blow hot air Since the warm air supply port 40 can be rotated in the horizontal state by the warm air and the rotational flow can be generated in the inner tank 4, the reliability can be improved, the unevenness in drying of the clothes can be prevented, and the quality can be improved. It can be enhanced.

  As described above, in the washing and drying machine according to the present invention, the guide plate of the hot air supply port can be closed only when it is not necessary, and it can be opened only in the drying process to blow out the hot air. It can be applied to other laundry dryer applications having a drying function such as a drum type because it can improve the quality and improve the quality.
