Japanese Patent Laid-Open No. 1-249097 JP 2011-24990 A

  When hanging and drying is performed by a washing dryer, it is desirable that the temperature of the space to which the hot air is supplied be as uniform as possible in order to prevent drying unevenness and the like. However, in practice, a temperature difference occurs depending on the position in the space due to the fixed hot air outlet. In order to reduce this temperature difference, it is effective to rotationally drive the stirring blade during suspension drying. Since the air (warm air) in the space is stirred by the rotation of the stirring blade, the temperature difference is reduced.

  However, since the driving power is required for the rotational drive of the stirring blade, considering the power saving, it is desirable that the rotational driving of the stirring blade during suspension drying is performed as much as necessary according to the temperature difference. . For example, it is desirable that the rotation of the stirring blade is not always performed, but only when the temperature difference in the space to which the hot air is supplied is relatively large.

  FIG. 4 shows a schematic cross-sectional view of the washer / dryer 1 from a lateral perspective with respect to the portion below the top plate 11 in order to facilitate understanding of the main structure of the washer / dryer 1. . In the washing and drying machine 1 shown in each of FIGS. 2 to 4, the left side is the front surface and the right side is the back surface.

[About the overall configuration of the washing dryer]
Hereinafter, the overall configuration and the like of the washing / drying machine will be described with reference to FIGS. The washing / drying machine 1 is a fully automatic type and includes a rectangular parallelepiped outer box 10. The outer box 10 is formed in a substantially rectangular parallelepiped shape, and its upper side is opened. The upper open portion of the outer box 10 is covered with a top plate 11.

  An operation unit (operation button or the like) 71 for receiving the operation of the washing / drying machine is provided at the front portion of the top plate 11. A back panel 14 is mounted on the back side of the top plate 11.

  In the central portion of the top plate 11, an entrance / exit (opening) 11 a for putting the laundry into the washing / drying machine 1 is opened. The entrance / exit 11a is opened and closed by a lid 15 pivotally supported by a hinge 15a provided at the front end of the back panel 14. The hinge portion 15 a is provided at a position on the rear side from the center in the front-rear direction of the washing / drying machine 1.

  Packing (not shown) is provided on the periphery of the lid portion 15, and when the lid portion 15 is fully closed, the space between the doorway 11 a and the lid portion 15 is sealed. Note that a claw 15c is provided on the front side of the lid portion 15 so that the lid portion 15 can be hooked (latched) by being hooked on the front side upper portion of the top plate 11 when fully closed. In a state where the claw 15c is hooked on the upper surface plate 11, the lid portion 15 does not open even when an upward force is applied.

  As shown in FIG. 2, the lid portion 15 is rotatable in the vertical direction (which can also be viewed as the front-rear direction) around the axis of the hinge portion 15 a. As shown in FIG. 2, the lid 15 is rotatable within a range from a position slightly smaller than 0 ° (fully closed position) to a position slightly larger than 90 ° (fully opened position).

  Accordingly, the user can open the lid portion 15 by rotating the lid portion 15 upward, and close the lid portion 15 by rotating the lid portion 15 downward. In a state in which the lid portion 15 is opened (in other words, in a state in which the entrance / exit 11a is opened), the user inputs laundry into the dehydration tank 30 or takes out laundry from the dehydration tank 30. can do. In a state where the lid portion 15 is closed (in other words, a state where the entrance / exit 11a is closed), a closed space including the inside of the dewatering tank 30 is formed inside the washing / drying machine 1. In the following description, this closed space may be referred to as “closed space SP”.

  A hook 15b for hanging the hanger 2 is provided on the surface (lower surface) of the lid portion 15 that faces the entrance / exit 11a. As a result, the user attaches the clothes (drying object) to the hanger 2 with the lid 15 open, as shown in FIG. 5 (front oblique upper perspective view) and FIG. 6 (side perspective view). Can be hung on the hook 15b. In FIGS. 5 and 6, the display of clothing is omitted.

  From this state, the lid 15 is closed by the user (in other words, the doorway 11a is closed), so that the clothes can be suspended in the dehydrating tank 30. As shown in FIG. 3 (particularly the upper left portion), the hook 15b has a cylindrical portion whose axis is the left-right direction. The hanger 2 has a hook-shaped portion, and the hook-shaped portion is hung on the cylindrical portion of the hook 15b so as to be rotatable in the front-rear direction.

  Thereby, even if the position of the cover part 15 fluctuates, the hanger 2 hung on the hook 15b is always downward (direction in which clothes are naturally suspended) due to the action of gravity. As will be described later, the washing / drying machine 1 can perform hanging drying on clothes hung using the hanger 2.

  Inside the outer box 10, a dewatering tank 30 that also serves as a washing tub and a water tank 20 that houses the dewatering tub 30 are housed. The dewatering tank 30 stores water in which detergent is dissolved or water for rinsing (hereinafter collectively referred to as “washing water”). Both the water tank 20 and the dewatering tank 30 have a shape of a bottomed cylindrical cup that opens upward, and are concentrically with the water tank 20 on the outside and the dewatering tank 30 on the inside, with the axes being vertical. Placed in.

  The water tank 20 is suspended by the suspension member 21. The suspension member 21 is provided at a total of four locations in such a manner that the lower outer surface of the water tank 20 and the inner corner of the outer box 10 are connected, and supports the water tank 20 so that it can swing within a horizontal plane.

  The dewatering tank 30 has a peripheral wall extending upwardly in a tapered shape, and there is no opening for allowing liquid to pass through the peripheral wall except for a plurality of dewatering holes 31 arranged in an annular shape at the top. That is, the dewatering tank 30 is formed in a so-called “no hole” type. An annular balancer 32 is attached to the edge of the upper opening of the dewatering tub 30 to suppress vibration when the dewatering tub 30 is rotated at a high speed for dewatering the laundry. A pulsator 33 for causing the washing water to flow in the tank is disposed on the inner bottom surface of the dewatering tank 30.

  A drive unit 40 is attached to the lower surface of the water tank 20. The drive unit 40 includes a motor 41 and a clutch / brake mechanism 43. The clutch / brake mechanism 43 is connected to the motor 41 by a belt 42, and the dewatering shaft 44 and the pulsator shaft 45 protrude upward. The clutch / brake mechanism 43 operates by electromagnetic force, and alternatively connects one of the dewatering shaft 44 and the pulsator shaft 45 to the motor 41. The clutch / brake mechanism 43 brakes the rotation of the dehydrating shaft 44 by electromagnetic force and releases the brake.

  The dewatering shaft 44 and the pulsator shaft 45 have a double shaft structure. The dewatering shaft 44 is disposed outside and the pulsator shaft 45 is disposed inside. The dehydrating shaft 44 penetrates the water tank 20 and is connected to the dehydrating tank 30 and pivotally supports the dehydrating tank 30. The pulsator shaft 45 passes through the water tank 20 and the dewatering tank 30 and is connected to the pulsator 33 to pivotally support the pulsator 33. Seal members for preventing water leakage are disposed between the dehydrating shaft 44 and the water tank 20 and between the dewatering shaft 44 and the pulsator shaft 45, respectively.

  On the lower side of the upper surface plate 11, a substantially cylindrical connecting component 17 having a side surface with a bellows shape is fixed. The top plate 11 and the water tank 20 are connected by the connecting component 17 so that the vibration of the water tank 20 due to the rotation of the dewatering tank 30 is absorbed.

  Further, the upper surface plate 11 and the connecting component 17 constitute a shielding portion that shields between the periphery of the entrance / exit 11 a and the upper surface of the water tank 20. A sealed space is formed between the water tank 20 and the entrance / exit 11a by the shielding portion. Thereby, the inner cover which opens and closes the upper surface of the water tank 20 is not required, and the lid 15 can be closed to perform washing and drying.

  Further, a water supply port is provided in a rear portion of the top plate 11. The water supply port is connected to city water through a water supply valve. Thus, the water supply port and the water supply valve constitute a water supply unit that supplies water to the dehydration tank 30. The water supply port is designed so that foreign matters such as dust do not enter inside.

  A drain hose 60 for draining water in the water tank 20 and the dewatering tank 30 to the outside of the outer box 10 is attached to the bottom of the water tank 20. The dewatering tank 30 is provided with four drain holes 62 on the same circumference, and each drain hole 62 and the drain hose 60 are connected by a drain duct 61. A drain valve 63 is provided in the drain duct 61. When the drain valve 63 is opened, the water in the dewatering tank 30 is drained through the drain duct 61 and the drain hose 60. Further, the water that flows out from the upper part of the dewatering tank 30 during dehydration passes between the peripheral wall of the water tank 20 and the peripheral wall of the dewatering tank 30 and is drained from the drain hose 60.

  FIG. 7 is a block diagram relating to a control system of the washing / drying machine 1. As shown in the figure, the washing / drying machine 1 has a lid opening / closing sensor 73 for detecting the open / closed state of the lid 15, a water level sensor 74 for detecting the water level of the dehydration tank 30, and the dehydration tank 30 in addition to the operation unit 71 described above. Various sensors such as a humidity sensor 76 for detecting the humidity inside are provided. The washing / drying machine 1 is also provided with a display unit 72 for displaying the operation state of the washing / drying machine 1.

  The drying unit 80 includes a blower, a heater, and the like, and has a function of supplying warm air to the closed space SP when the hanging drying operation is performed. More specifically, the drying unit 80 is installed on the upper surface plate 11 on the rear side of the outer box 10, and is directed from the outlet 80 a toward the inner peripheral wall of the dewatering tank 30 as indicated by an arrow in FIG. 4. Blow out warm air.

  The washing / drying machine 1 is provided with a first temperature sensor 75a and a second temperature sensor 75b (collectively referred to as “temperature sensor 75”) as temperature sensors for detecting the temperature of the closed space SP. Yes. The temperature sensor 75 is mainly used for evaluating a temperature difference in the closed space SP when a hanging / drying operation described later is performed, that is, when warm air is supplied to the closed space SP in a state where clothes are suspended. Is provided.

  Therefore, it is desirable that the first temperature sensor 75a is provided at a position where the temperature is likely to increase during the hanging and drying operation, and the second temperature sensor 75b is desirably provided at a position where the temperature is difficult to increase. In accordance with this gist, the first temperature sensor 75a is provided so as to detect the temperature near the outlet 80a, and the second temperature sensor 75b detects the temperature at a position sufficiently away from the outlet 80a. Is provided.

  In the present embodiment, as shown in FIG. 4, the first temperature sensor 75 a is located closest to the outlet 80 a in the upper part of the water tank 20, and the second temperature sensor 75 b is farthest from the outlet 80 a in the upper part of the water tank 20. (Positions on the side opposite to the outlet 80a in the front-rear direction). Thus, the 1st temperature sensor 75a and the 2nd temperature sensor 75b are each arrange | positioned in the position where the distance from the blower outlet 80a differs.

  However, the specific arrangement position of the temperature sensor 75 is not limited to that described above. For example, the second temperature sensor 75 b may be disposed on the inner side surface or the inner bottom surface of the dehydration tank 30. During the hanging and drying operation, the position opposite to the air outlet 80a seen from the suspended clothes is difficult to reach because the warm air from the air outlet 80a is easily blocked by the clothes. It is assumed that the temperature is relatively difficult to rise. Therefore, it is desirable that the second temperature sensor 75b is provided at a position opposite to the air outlet 80a as viewed from the suspended clothes.

  In addition, the washing / drying machine 1 includes a microcomputer MC that controls each unit so that the washing / drying machine 1 operates appropriately in accordance with user operations, detection information of various sensors, and the like. The microcomputer MC is disposed, for example, at the upper back of the outer box 10 and controls the display unit 72, the motor 41, the drying unit 80, and other driving mechanisms.

  In the washing / drying machine 1 having the above-described configuration, the laundry is put into the dehydrating tank 30 from the entrance / exit 11a, and the lid 15 is closed. When the washing condition is selected by the user and the start of washing is instructed, the lid opening / closing sensor detects that the lid portion 15 is closed, and the operation of the washing process is executed.

  In the washing process, the drain valve 63 is closed, the water supply valve is opened, and water is supplied to the dehydration tank 30 from the water supply port. When a predetermined amount of water accumulates in the dewatering tank 30, the water supply valve is closed by detection of the water level sensor. Next, the clutch / brake mechanism 43 connects the pulsator shaft 45 to the motor 41 to drive the motor 41. Thereby, the pulsator 33 rotates and the washing operation is performed by stirring the water in the dewatering tank 30.

  When a predetermined time has elapsed since the start of the washing process, the drain valve 63 is opened to drain the water in the dewatering tank 30, and the dewatering shaft 44 is connected to the motor 41 by the clutch / brake mechanism 43. Thereby, the dehydrating tank 30 is rotated at a high speed by the drive of the motor 41 and the dehydrating operation is performed. The water splashed from the laundry by the high-speed rotation of the dewatering tank 30 flows out from the drainage duct 61 and the dewatering hole 31.

  When a predetermined time has elapsed after starting the dehydrating operation, the motor 41 is stopped, the drain valve 63 is closed, and the water supply valve is opened. When a predetermined amount of water accumulates in the dewatering tank 30, the water supply valve is closed by detection of the water level sensor. Next, the clutch / brake mechanism 43 connects the pulsator shaft 45 to the motor 41 to drive the motor 41. As a result, the pulsator 33 rotates, and the rinsing operation is performed by stirring the water in the dewatering tank 30.

  When a predetermined time has elapsed after starting the rinsing operation, the above dehydration operation is performed again. When the dehydrating operation is performed for a predetermined time, the washing process ends. In addition, the washing and drying machine 1 starts the hanging and drying operation when an instruction to perform the hanging and drying operation is given by the user.

  The hanging and drying operation is an operation of drying the suspended clothes (suspending and drying) by supplying warm air into the dehydrating tank 30 and circulating it. That is, in the washing / drying machine 1, the clothes are suspended in the closed space SP by hanging the hanger 2 to which clothes are attached in advance on the hook 15 b and closing the lid 15. In this state, the laundry dryer 1 performs the hanging and drying operation to realize the hanging and drying of the clothing.

[About hanging drying operation]
Next, the contents of the hanging drying operation performed by the washing / drying machine 1 will be described with reference to the flowchart shown in FIG.

  With the start of the hanging drying operation, the microcomputer MC controls the drying unit 80 to start supplying hot air into the closed space SP (step S0). The supply of warm air is continued until the hanging and drying operation is completed. By supplying the warm air, the clothes suspended in the closed space SP are gradually dried.

  In addition, after the suspension drying operation is started, the microcomputer MC monitors whether the drying end condition is satisfied (step S1). This drying end condition is a condition set in advance as a condition for determining whether the suspension drying operation should be terminated (that is, whether the suspension drying has already been sufficiently performed). The drying end condition is set to, for example, a condition that the detection result of the temperature sensor 75 or the humidity sensor 76 exceeds a predetermined reference value, or a condition that the elapsed time from the start of the hanging drying operation has reached a predetermined time. Can be done.

  If the drying end condition is satisfied (Y in step S1), the microcomputer MC ends the hanging drying operation. Further, the microcomputer MC monitors whether the drying end condition is satisfied, and continuously calculates the difference between the latest detected temperature of the first temperature sensor 75a and the latest detected temperature of the second temperature sensor 75b. It is also monitored whether the result of exceeds a predetermined first threshold value (step S2).

  It can be said that the result of the calculation represents a temperature difference between different positions in the closed space SP. Therefore, when the result of the calculation exceeds the first threshold value, it can be said that there is a relatively high need to reduce the temperature difference in the closed space SP from the current state in order to prevent drying unevenness in hanging drying. Therefore, when the result of the calculation exceeds the first threshold value (Y in step S2), the microcomputer MC controls the motor 41 to rotate the pulsator 33 (step S3), and the operation of step S1 is performed. repeat.

  That is, the microcomputer MC starts the rotational drive when the pulsator 33 is not rotationally driven at the present time, and maintains the rotational drive when the pulsator 33 is already rotationally driven. Thereby, the air inside the closed space SP (in particular, the inside of the dehydrating tank 30) is agitated, and the temperature difference in the closed space SP is reduced compared to when the pulsator 33 is not rotationally driven.

  In addition, when hanging dry, the pulsator 33 is not covered with clothes unlike the case where drying is performed in a state where the clothes are stacked on the bottom of the dewatering tank 30. Therefore, the air inside the closed space SP is easily agitated by the rotational drive of the pulsator 33.

  On the other hand, if the calculation result in step S2 does not exceed the first threshold, it can be said that the necessity of reducing the temperature difference in the closed space SP from the current level is relatively low. Therefore, when the result of the calculation does not exceed the first threshold (N in Step S2), the microcomputer MC controls the motor 41 so as not to drive the pulsator 33 to rotate (Step S4), and performs the operation of Step S1. repeat.

  That is, the microcomputer MC stops the rotational drive when the pulsator 33 is rotationally driven at the present time, and maintains the state when the pulsator 33 is not rotationally driven. Thereby, compared with the case where the pulsator 33 is rotationally driven, power consumption is suppressed.

[Modified example of hanging drying operation]
As described above, the contents of the hanging and drying operation according to the present embodiment are considered so that the pulsator 33 is rotated and driven by the necessary amount depending on the situation during the hanging and drying operation. However, it is possible to add various modifications to the contents of the hanging and drying operation so as to follow this purpose. Several modifications of the hanging and drying operation will be described below.

  First, as a first modification, there is an example in which the temperature difference in the closed space SP is evaluated without using the detection result of the first temperature sensor 75a. More specifically, as shown in the flowchart of FIG. 9, the operation of step S2 ′ is performed instead of the operation of step S2. The operation in step S2 ′ is an operation for monitoring whether the latest detected temperature of the second temperature sensor 75b exceeds a predetermined second threshold. When the second threshold value is exceeded (Y at Step S2 ′), the operation at Step S3 is executed, and when it is not exceeded (N at Step S2 ′), the operation at Step S4 is executed.

  It is considered that the temperature of the warm air immediately after the blowout is substantially constant. Therefore, when the temperature detected by the second temperature sensor 75b is low, the temperature difference in the closed space SP is assumed to be large. Therefore, also in the first modification, the pulsator 33 is rotationally driven during suspension and drying by a necessary amount depending on the situation. According to the first modification example, it is considered that the temperature difference detection accuracy is not as good as that of the embodiment described above, but the installation of the first temperature sensor 75a is omitted to reduce the manufacturing cost. It becomes possible.

  In addition, the rotational speed of the pulsator may be controlled in a plurality of stages. In this case, generally, the higher the rotational speed, the stronger the air is stirred, but the greater the electric power required for rotational driving.

  Therefore, as a second modified example, the pulsator 33 is controlled to be either in a state where it is rotationally driven (corresponding to a state where the rotational speed is 100%) or in a state where it is not rotationally driven (corresponding to a state where the rotational speed is 0%). An example of controlling the rotational speed of the pulsator 33 in a plurality of stages instead of (that is, controlling in one stage) is given. For example, one stage is set to 20%, and the rotation speed of the pulsator 33 is controlled to five stages.

  More specifically, as shown in the flowchart of FIG. 10, the operation of step S3 ′ is performed instead of the operation of step S3, and the operation of step S4 ′ is performed instead of the operation of step S4.

  The operation in step S3 ′ is an operation in which the microcomputer MC controls the motor 41 so that the rotational speed of the pulsator 33 is increased by one step from the current level. When the rotational speed is already 100%, the rotational speed is maintained. Thereby, the air inside the closed space SP (in particular, the inside of the dehydrating tank 30) is more strongly stirred, and the temperature difference in the closed space SP can be easily reduced compared to the current situation.

  The operation in step S4 ′ is an operation in which the microcomputer MC controls the motor 41 so that the rotational speed of the pulsator 33 is lowered by one level from the current state. If the rotational speed is already 0% (the state in which the pulsator 33 is not rotationally driven), the state is maintained. This makes it easier to reduce power consumption compared to the current situation. Also in the second modified example, the pulsator 33 is rotationally driven by the necessary amount depending on the situation during the hanging drying.
