Description

  The present invention relates to a dryer or a washing dryer provided with means for drying clothes.

  In general clothes dryers and washing / drying machines, warm air is blown from one direction of a rotating drum for storing clothes and the warm air is discharged from the opposite direction. However, as the amount of clothing increases, clothing becomes difficult to move in the rotating drum, so the clothing on the side where the hot air hits dries quickly, whereas the clothing on the other side is difficult to hit with the hot air and the drying speed is slow. . For this reason, if the operation is terminated at a temperature of about T1 giving priority to the influence on the clothing, the rear clothing becomes insufficiently dried. Conversely, if the operation is performed so that there is no uneven drying, the temperature of the front clothing rises too much. There is a problem that it ends up.

  Thus, dryers and washing dryers that have improved drying efficiency by blowing warm air from a plurality of directions of the rotating drum have been proposed. For example, Patent Document 1 below includes a plurality of circulation paths for supplying warm air to the rotating drum, and the first circulation path supplies warm air from the bottom side of the rotating drum using the first air blowing means. As the second circulation path, there is disclosed a clothes dryer for supplying warm air from the opening side of the rotating drum using a second air blowing means.

JP 2006-354 A

  In the invention described in Patent Document 1, since there are a plurality of circulation paths, not only the circulation path as a whole becomes longer and the structure becomes complicated, but also the chance of heat loss increases, leading to an increase in power consumption.

  An object of the present invention is to provide a dryer or a washing dryer that reduces power consumption while preventing uneven drying of clothes.

  In order to solve the above-described problems, the present invention is provided on a rotating drum for storing clothing, a motor for driving the rotating drum, an outer tub for containing the rotating drum, and an inner peripheral surface of the rotating drum. In a dryer provided with a lifter that sweeps up the clothes as the rotating drum rotates, a flow path for drying air is provided inside the lifter.

  It is possible to provide a dryer or a washing / drying machine with reduced power consumption while preventing uneven clothing drying.

  Furthermore, components (not shown) related to water supply such as a water supply electromagnetic valve, a bath water pump, and a water level sensor are provided behind the detergent supply chamber / finishing agent input chamber 19. Further, the upper surface cover 1e shown in FIG. 1 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 charging chamber / finishing agent charging chamber 19 is connected to the outer tub 2 and supplies washing water to the outer tub 2 by opening a water supply electromagnetic valve or operating a bath water pump.

  Further, as shown in FIG. 3, a drying duct 29 is installed vertically inside the back surface of the housing 1, and a lower portion of the duct is connected to a rubber bellows tube at an exhaust port 22 provided below the back surface of the outer tub 2. 29a is connected. A water cooling / dehumidifying mechanism (not shown) is built in the drying duct 29, and cooling water is supplied from the water supply electromagnetic valve to the water cooling / dehumidifying mechanism. The cooling water flows down along the wall surface of the drying duct 29, enters the outer tub 2 from the exhaust port 22, 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 as shown in FIG. 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. Further, an opening is provided in the lower surface of the insertion portion of the dry filter 8 of the filter duct 27, this opening is connected to the intake duct, and the other end of the intake duct is connected to the intake port of the blower unit 28. Yes.

  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 discharge port of the blower unit 28 is connected to the hot air duct 30. The hot air duct 30 is connected to a front outlet 32 provided in the outer tank cover 2d through a rubber bellows tube 30a 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 front outlet 32 is provided at a position on the upper right side of the outer tank cover 2d, and the distance to the front outlet 32 is set. I try to keep it as short as possible. For this reason, an increase in pressure loss can be prevented and high-speed wind can be efficiently blown. A temperature sensor (not shown) is provided at the drain port 2b and the air inlet and outlet of the blower unit 28.

  Here, the detail of the front blower outlet 32 is demonstrated using FIG. The front air outlet 32 is provided along the opening 2c from the front side of the outer tank cover 2d, and flow paths 32b and 32c are formed therein. A bellows pipe joint 30b is attached to the entrance of the front outlet 32, and a nozzle 32d is formed at the exit of the flow path 32c. The inner diameter of the opening 2c of the outer tub cover 2d and the inner diameter of the opening 3a of the washing / dehydration tub 3 are set substantially the same so that clothing does not enter the gap between the washing / dehydration tub 3 and the outer tub cover 2d. Yes. For this reason, the outlet part of the front outlet 32 is formed so as to protrude inward from the inner peripheral surface of the opening part 2c of the outer tub cover 2d so that the nozzle 32d opens toward the inside of the washing and dewatering tub 3. It is composed. By doing in this way, the warm air from the nozzle 32d directly hits the clothes in the washing and dewatering tub 3.

  Note that if the amount of protrusion at the outlet of the front air outlet 32 is too large, the movement of clothing is hindered during washing or drying, so that the amount of protrusion is reduced to a flat slit shape and the opening 2c of the outer tub cover 2d. And the surface shape of the outlet part changes smoothly. Further, the flow path 32b and the flow path 32c are configured so that there is no useless protrusion or a sudden change in the flow direction, and the flow path area gradually decreases toward the nozzle 32d. By doing so, it is possible to reduce pressure loss and fluid sound that occur when high-speed wind flows through the channels 32b and 32c.

  Next, the structure of the lifter 34 in a present Example is demonstrated using FIGS.

  First, as shown in FIG. 5, a suction port 34 a is provided at one end side of the lifter 34, specifically, at an end portion on the opening side of the washing / dehydrating tub 3. Then, when the suction port 34a moves with the rotation of the washing and dewatering tub 3 and reaches a position facing the tip of the nozzle 32d that is an air supply port for drying air, the state shown in FIG. 6 is obtained.

  As a result, the drying air ejected from the nozzle 32d is guided to the flow path provided inside the lifter 34, and a plurality of the air provided on the other end side of the lifter 34, that is, the surface on the bottom side of the washing / dehydrating tub 3 is provided. The air is blown out from the suction hole 34b into the washing and dewatering tub 3. For this reason, it becomes possible to blow warm air directly on the clothes near the bottom of the washing and dewatering tank 3.

  When the suction port 34a is not in the position shown in FIG. 5 (for example, in the position shown in FIG. 4), the clothes near the opening of the washing and dewatering tub 3 are lifted up and dropped by gravity. Since the warm air blown from the nozzle 32 directly blows, the clothes are pushed out by the wind, and the wrinkles of the clothes are stretched.

  Here, during the drying operation, the washing and dewatering tub 3 is rotated at regular intervals in the reverse direction to the forward direction. Therefore, if the motor is controlled so that the suction port 34a is positioned at the position shown in FIG. 5 at the timing when the rotation direction is reversed, a large amount of drying air can be guided to the vicinity of the bottom of the washing and dewatering tub 3.

  FIG. 7 shows a cross section and a plane of the lifter 34 in the present embodiment. One end side of the lifter 34 is extended in the radial direction of the washing / dehydrating tub 3, and the tip thereof is extended in the rotation axis direction of the washing / dehydrating tub 3, thereby forming a suction port 34 a. The end of the suction port 34a is fixed to the fluid balancer 3c or the washing / dehydrating tub 3 by the fastening body 34d, and the other end of the lifter 34 is fixed to the washing / dehydrating tub 3 by the fastening body 34e.

  The suction port 34a has a shape along the wall surfaces of the washing / dehydrating tub 3 and the fluid balancer 3c. For this reason, the flow path inside the suction port 34a is narrow in the radial direction and the rotation axis direction of the washing / dehydrating tub 3, and wide in the circumferential direction of the washing / dehydrating tub 3 (at least than the main body portion of the lifter 34). Yes. Thereby, not only the volume reduction in the washing and dewatering tub 3 is suppressed, but more drying air can be taken in from the nozzle 32d.

  In addition, the suction hole 34b is configured by a plurality of lattice-shaped holes so that clothing or the like does not enter. In addition to the suction holes 34b, a plurality of through holes 34c are provided in the ridge portion on the surface of the lifter 34, and water and air enter and exit.

  As described above, according to the present embodiment, the air for drying can be alternately blown from both the bottom side and the opening side of the washing and dewatering tub 3 with a simple structure, while preventing the clothes from drying unevenly. It becomes possible to suppress power consumption.

  In this embodiment, the air supply port for blowing the drying air into the washing and dewatering tub 3 is provided on the opening side of the outer tub 2, but this air supply port may be provided on the bottom side of the outer tub 2. good. In that case, the positions of the suction port 34a and the suction hole 34b of the lifter 34 are reversed, and the direction of the drying air flowing through the flow path inside the lifter 34 is also reversed.

  Next, a second embodiment of the present invention will be described with reference to FIGS. The washing / drying machine of the present embodiment has a heat pump 35 installed in the lower part of the housing 1 in place of the heater 31 in the first embodiment.

  As shown in FIG. 8, in this embodiment, an air supply duct 37 is connected to the upper part of the bottom surface of the outer tub 2, and the air blown by the air blowing means 36 provided upstream of the air supply duct 37 is dried. The air is supplied from the air supply port 21 into the washing and dewatering tank 3 as working air. Further, an exhaust port 22 is provided in the upper part of the outer tub 2 on the opening side, and hot air dampened by removing moisture from the clothes is discharged out of the washing / dehydrating tub 3. When the discharged hot air reaches the heat pump 35, it is dehumidified by a heat absorber (not shown), heated by a heat radiator (not shown), and again washed through the blower means 36 and the air supply duct 37. It circulates in the cum dewatering tank 3. Therefore, since the drying air supplied from the upper part of the bottom surface of the outer tub 2 directly hits clothes near the bottom of the washing and dewatering tub 3, a sufficient drying effect can be obtained.

  Further, the lifter 34 of the present embodiment includes a drying air suction port provided at an end portion on the bottom side of the washing / dehydrating tub 3, a drying air channel provided therein, and the washing / dehydrating tub 3. It has a plurality of blowing holes 34b provided on the opening side. Therefore, as shown in FIG. 9, when the suction port of the lifter 34 reaches a position facing the air supply port 21 as the washing and dewatering tub 3 rotates, the drying air flows from the suction port, 34 blows out from the blowout holes 34 b through the flow passages 34, and takes away moisture from the clothes in the vicinity of the opening of the washing and dewatering tub 3.

  Thus, also in this embodiment, since the air for drying can be blown out from the bottom side and the opening side of the washing and dewatering tub 3 with a simple structure, it is possible to reduce power consumption while preventing uneven drying of clothes. It is possible to suppress.

  Next, a third embodiment of the present invention will be described with reference to FIGS. In this embodiment, unlike the second embodiment, the heat pump 35 is installed on the top of the housing 1. In the present embodiment, since the heat pump 35 is located above the outer tub 2, the upper portion of the bottom surface of the outer tub 2 from the exhaust port 22 on the opening side of the outer tub 2 through the heat pump 35 and the air blowing means 36. The circulation path to the air supply port 21 is short, and heat loss is reduced.

  Moreover, since the heat pump 35 is equipped with a heavy device such as a compressor (not shown), if these are supported by the outer tub 2, a role of a weight to suppress the shaking of the outer tub 2 can be expected. This will also reduce vibration and noise.
