Description

  The present invention relates to a drum-type washing and drying machine that performs laundry washing and drying using a heat pump cycle.

  A drum-type washing and drying machine has a drum rotatably arranged in a horizontal or substantially horizontally inclined water tank, and the drum is rotated around a rotating shaft to wash, rinse and dehydrate laundry. , Until drying. To dry the laundry containing moisture, the air inside the drum containing moisture is exhausted outside the water tank, dehumidified by the dehumidifying means, heated by the heating means, and pressurized and accelerated by the fan. The laundry is dried by repeating a drying cycle in which moisture is evaporated from the laundry by blowing the inside of the drum.

  A washing / drying machine equipped with a heat pump cycle includes a compressor, a heat exchanger for cooling that is a dehumidifying means, and a heat exchanger for heating that is a heating means. The high-temperature and high-pressure refrigerant that has been compressed is sent to a heating heat exchanger to heat the air, the air is dehumidified by the dehumidifying heat exchanger, and then the low-temperature and low-pressure refrigerant is collected in the compressor. The clothes are then dried by composing a cycle that is compressed and circulated again.

  JP-A-2006-109976, JP-A-2004-135715, and JP-A-7-51493 are conventional techniques for washing and drying machines equipped with a heat pump cycle (heat pump device).

  Japanese Patent Laid-Open No. 2006-109976 discloses a structure of a washer / dryer having a heat pump cycle and a heat exchanger provided in the same vibration system as the water tank, and a heat exchanger and a compressor provided in the same vibration system as the water tank. The structure of the washing / drying machine is disclosed. Japanese Patent Application Laid-Open No. 2004-135715 discloses a configuration in which a heat exchanger and a compressor are arranged above the uppermost part of the washing water drainage path. Japanese Patent Application Laid-Open No. 7-51493 discloses a configuration including a cooling heat exchanger and a heating heat exchanger that are equipment for supplying dry hot air to an upper portion of a drying chamber provided with a rotating drum.

JP 2006-109976 A JP 2004-135715 A Japanese Unexamined Patent Publication No. 7-51493

  In order to efficiently evaporate the moisture from the clothes, it is preferable that the warm air is directly brought into contact with the clothes. However, as in the configuration disclosed in Japanese Patent Application Laid-Open No. 2006-109976, the outlet is connected to the water tank. In the configuration provided on the bottom surface (or top surface) facing the open end, warm air passes from the outside of the aquarium to the bottom surface (top surface) of the drum and is then blown to the clothing, so the bottom surface (top surface) of the drum is meshed. Even if the draft resistance is reduced due to the configuration or the like, the warm air is scattered by hitting the mesh and the wind speed is lowered. On the other hand, when the outlet is provided on the opening end side of the water tank, the warm air is blown directly onto the clothing, which is preferable because the evaporation of moisture is promoted.

  In order to provide the outlet on the opening end side of the water tank, it is necessary to provide a heat exchanger on the upper surface of the water tank. For example, it is realizable by the structure disclosed by Unexamined-Japanese-Patent No. 2004-135715. However, the above-described configuration is a configuration in which the compressor, which is a heavy object, is disposed above, so that the center of gravity increases and is unstable.

  In Japanese Patent Laid-Open No. 7-51493, it is a central air conditioner that supplies the refrigerant to the heat exchanger, and does not describe the arrangement of the compressor.

  Therefore, the object of the present invention is to allow a structure in which hot air is directly blown into the garment from the opening end of the water tank, the garment drying efficiency is high, and the arrangement of the heat exchanger and the compressor is stable. It is to provide a washing and drying machine.

  For the above purpose, the drum type washing and drying machine according to the present invention comprises a cylindrical water tank that is elastically supported horizontally or inclined with one surface as an open end and the other end as a bottom surface, and the water tank inside the water tank. A rotating drum that is coaxially and rotatably supported concentrically with one end as an open end, a lid that is openable and closable at the opening end of the water tank and the rotating drum, and a drive motor that rotationally drives the rotary drum; An air duct that forms an air flow path that connects the exhaust port and the blowing port, with an exhaust port opened near the bottom of the water tank as an upstream, and a blowing port opened at the opening end of the water tank as a downstream; In a washer / dryer comprising a heat pump cycle having a compressor, a dehumidifying heat exchanger, and a heating heat exchanger, and including the dehumidifying heat exchanger and the heating heat exchanger in the air duct, Below the tank And location, the heat exchanger is arranged above the said water tank is further intended to the said compressor and the heat exchanger are both constituted by disposing the washer-dryer body identical to the vibration system.

  According to the present invention, in a washing and drying machine for drying clothes using a heat pump cycle, the compressor is provided on the base below the water tank, the heat exchanger is provided above the water tank, the compressor and the heat exchanger, Are installed in the same vibration system as the main body of the washer / dryer. Since the vibration of the water tank is not transmitted to the heat pump cycle, the life reliability is high and the depth of the apparatus can be reduced, so that a thin washer-dryer can be realized without increasing the installation area.

  Examples of the present invention will be described below.

  The structure of the drum type washing machine according to the present invention will be described below with reference to the drawings.

  FIG. 1 is a partially cut perspective view showing the whole and internal structure of a drum type washing / drying machine according to the present invention, FIG. 2 is a rear view, FIG. 3 is a right side view, FIG. 4 is a perspective view seen from the back, and FIG. FIG. 6 is a sectional view for explaining the movement of clothes during washing and drying. FIG. 4 shows a state in which the lint filter is extracted upward.

In the drum type washing / drying machine main body 1, a water tank 4 whose front side is opened on a base 3 is supported by a suspension 2 so as to be inclined substantially horizontally, and the suspension 2 reduces vibration during operation of the water tank 4. For this purpose, the elastic force of the spring and, for example, oil is enclosed to generate a damping force. Inside the water tank 4, a rotating drum 5 that is pivotally supported and opened on the front side is disposed, and is rotated by a driving force of a driving motor 8 provided on the back surface of the water tank 4.
An opening 6 is formed on the front side of the drum-type washing / drying machine main body 1, and the user puts the clothes 14 into the drum through the opening 6 or takes out the clothes 14 that have been washed and dried. Can do. In order to take out the garment 14, a lid 7 for opening and closing the opening 6 is provided. For example, the lid 7 is pivotally supported and can be opened to the open position shown by 7 '.

  The opening 6 on the front side of the main body 1 and the front side of the water tank 4 are connected by a bellows 9 formed of a flexible material such as rubber, for example, and when the lid 7 is closed, a part of the bellows 9 is connected. Is in contact with the lid 7 to ensure water sealing even when the water tank 4 vibrates.

  A drying means 11 is disposed on the upper part of the water tank 4. The drying means 11 in the present invention includes an exhaust duct 13, a lint filter 16, a dehumidifying heat exchanger 26, a heating heat exchanger 27, a fan 18, and a blowing port 23, and the same vibration as the washing / drying machine main body 1. It is connected to the water tank 4 via the bellows 15 and the blow-in bellows 25 and is separated from the vibration system of the water tank 4 and constitutes an air duct that allows air to circulate. ing. The dehumidifying heat exchanger 26 and the heating heat exchanger 27 form a part of a heat pump cycle as will be described later, and the dehumidifying heat exchanger 26 is cooled by the refrigerant, while the heating heat exchanger 27 is heated by the refrigerant. It is.

  A water supply means 10 is provided at the upper left corner when viewed from the front surface of the water tank 4 and is connected to a water pipe by a water supply hose (not shown) so that washing water can be supplied. A detergent charging means 17 is provided on the opening end 6 side of the water supply means 10, and the user can input a laundry detergent and a softening agent.

  Exhaust duct that discharges moist air containing moisture from the clothes 14 inside the drum 5 in the direction of arrow 30 from the exhaust port 12 provided at the lower back of the aquarium 4 and blows air from below substantially upward along the back of the aquarium 4 13 is provided. The water tank 4 and the exhaust duct 13 are connected by a telescopic bellows 15 so that the vibration of the water tank 4 is not transmitted to the exhaust duct 13. On the upper surface of the outer tub 4, the exhaust duct 13 is connected to a heat exchanger case 24, and the heat exchanger case 24 extends substantially from the back side to the front side along the rotation axis of the drum 5, and the air is an arrow. Air is blown in the direction of 31.

  The heat exchanger case 24 provided on the uppermost surface of the washing / drying machine main body 1 has a lint filter 16, a dehumidifying heat exchanger 26, and heating heat in order from the upstream side where air is blown, that is, from the back side of the washing / drying machine main body 1. The exchangers 27 are included in parallel with each other in order, and are provided so that air can pass therethrough.

  Since the dehumidifying heat exchanger 26 and the heating heat exchanger 27 are desired to reduce the ventilation resistance of air, it is not desirable to make them thick in the blowing direction. Therefore, it is better that the heat exchanger is thin in the blowing direction and the area of the surface perpendicular to the blowing direction is increased. Here, since the air blowing direction is directed from the rear to the front of the washing / drying machine main body 1, the heat exchangers 26 and 27 are arranged so that the area when viewed from the rear is maximized as shown in FIG. desirable. Furthermore, in order to reduce the overall height of the washing / drying machine main body 1 and to reduce the size, it is desirable to increase the width dimension w of the heat exchanger and reduce the height dimension h. That is, the width w of the heat exchanger is set to be ½ or more of the width of the washing / drying machine main body 1 so that the height h is minimized, and a necessary heat exchanger area w × h is obtained. Good.

  The heat exchanger case 24 is placed on the upper surface of the upper reinforcing plate 19 that is a connecting plate that connects the case side plates constituting the left and right side surfaces with screws and the like in the upper part of the washing / drying machine main body 1. Can be provided. The water supply means 10 can be provided on the lower surface of the upper reinforcing plate 19 in a space between the water tank 4.

  Since the heat exchanger case 24 is provided on the upper surface of the upper reinforcing plate 19, when the dimensions of the heat exchangers 26 and 27 are enlarged, the lower side of the upper reinforcing plate 19 may be the same, and heat exchange is performed. Since the dimensions of the heat exchanger can be increased by increasing the height of the container case 24 and the washing / drying machine main body 1, it is easy to change and is convenient.

The lint filter 16 has a substantially flat plate shape with an area substantially the same as that of the dehumidifying heat exchanger 26, and is provided substantially parallel to the dehumidifying heat exchanger 26 and perpendicular to the surface into which air flows.
The lint filter 16, the dehumidifying heat exchanger 26, and the heating heat exchanger 27 are arranged in series in the air flow direction, and lint, which is fiber waste contained in the air, is collected by the lint filter 16. The lint filter 16 is provided so as to be removable from the upper surface side of the washing / drying machine main body 1, and the user can remove the lint filter 16 upward to clean the lint collected on the surface of the lint filter 16.

  Since the lint filter 16 is provided in series in parallel with the heat exchangers 26 and 27, it is easy to provide the area of the mesh for lint collection of the lint filter 16 substantially equal to the area of the heat exchanger. Therefore, the lint filter 16 is preferable because it is less likely to be clogged and the cleaning interval can be increased. Further, since the lint filter 16 can be formed into a flat plate shape, it is easier to clean as compared with a shape having irregularities.

  When the lint collected in the lint filter 16 passes through the dehumidifying heat exchanger 26, it is cooled to a dew point or less to condense and condense, and the condensed water droplets are provided on the bottom surface of the heat exchanger case 24. Accumulated in the drain receiver 28 which is a recess, the water is drained via a drain hose 29 connected to the drain receiver 28. The other end of the drain hose 29 is connected to the exhaust duct 13, for example, and is drained into the water tank 4 through the exhaust duct 13 and the exhaust port 12.

  By the way, since the water accumulated in the drain receiver 28 is water cooled by the dehumidifying heat exchanger 26, the temperature is low. The drain hose 29 is connected to the exhaust duct 13 and drained as indicated by an arrow 34 and flows along the inner wall of the exhaust duct 13 to the exhaust port 12, so that the humid air flowing inside the exhaust duct 13 as indicated by the arrow 30. Since the air is cooled and dew condensation occurs in the exhaust duct 13, it is preferable to promote dehumidification of the humid air. If the connection port 39 connected from the drain hose 29 to the exhaust duct 13 is provided at a position lower than the drain receiver 28, the moisture accumulated in the drain receiver 28 flows through the drain hose 29 as indicated by the arrow 34 by its own weight. Since it flows in the inside of the duct 13, a pump becomes unnecessary and it is convenient.

  The air that has been cooled and dehumidified after passing through the dehumidifying heat exchanger 26 is blown in the direction of the arrow 31, heated through the heating heat exchanger 27, and then rotated by a rotating blade (not shown) provided inside the fan 18. Introduced in the center. As described above, the fan 18 is a so-called centrifugal sirocco fan or turbo fan, and the rotating blades are rotated by the fan motor 20 to accelerate the air by centrifugal force. The outer shape of the fan 18 will be described. The rotating blade has a substantially disk shape, and the main body of the fan 18 has a substantially cylindrical shape with a spiral shape gradually increasing in radius around the rotating blade. The air that is blown out is guided in the direction of the exhaust port of the fan. An opening for air to flow in is provided at the rotation center of the rotating blade on one surface of the fan 18, and a fan motor 20 having a smaller diameter than the outer diameter of the fan 18 is concentric with the rotating blade on the opposite side of the opening. It has a form protruding.

  The accelerated air is blown into the drum 5 in the direction indicated by the arrow 33 through the blow bellows 25 from the blow opening 23 opened at the upper front of the water tank 4. The warm air blown into the drum heats the clothes 14 to evaporate the moisture to become humid air, and is sucked out of the water tank 4 from the exhaust port 12 and dehumidified through the exhaust duct 13 again. The wet garment is dried by continuously repeating the drying cycle as described above.

  According to the present invention, the air inlet 23 is open at the upper part of the front surface of the water tank 4, and the warm air blown from the air inlet 23 is configured to be blown directly on the clothing without obstruction. It is preferable because evaporation of moisture from the clothes can be promoted to shorten the drying time. Furthermore, by blowing high-pressure air directly onto clothing at a high speed, there is an effect of extending the wrinkles of the clothing and improving the dry finish.

  Next, the configuration and operation of the heat pump cycle will be described. The heat pump cycle includes a compressor 35, a dehumidifying heat exchanger 26, a heating heat exchanger 27, an expansion valve (not shown), and a pipe through which a refrigerant flows.

  The compressor 35 that compresses the refrigerant is provided in the vicinity of the bottom surface of the base 3 in the same vibration system as the washing and drying machine main body 1 via, for example, a vibration-proof rubber (not shown), and the exhaust duct with respect to the drive motor 8. 13 is provided on the substantially opposite side. Since the compressor 35 has a large mass, providing the compressor 35 in the vicinity of the bottom surface of the washing / drying machine main body 1 has a low center of gravity and thus is stable. The compressor 35 transmits vibrations during operation to the base 3, but the base 3 is installed on the floor surface of the installation site via rubber feet or the like, so that the compressor 35 is stable and vibrations. Is convenient because it will not be excessive.

  The high pressure side of the compressor 35 and one end of the heating heat exchanger 27 are connected by a pipe 36, and the pipe 37 connected to the other end of the heating heat exchanger 27 passes through an expansion valve (not shown) before dehumidification. It is connected to one end of the heat exchanger 26. A pipe 38 connected to the other end of the dehumidifying heat exchanger 26 is disposed adjacent to the pipe 36 and connected to the low pressure side of the compressor 35.

  The refrigerant compressed to a high temperature and a high pressure by the compressor 35 is sent to the heating heat exchanger 27 through the pipe 36 and is dehumidified by the air passing through the heat exchanger case 24, that is, the dehumidifying heat exchanger 26, and becomes a low temperature. As the air is heated, the refrigerant is deprived of heat and changes from the gas phase to the liquid phase. The refrigerant further leaves the heating heat exchanger 27 and passes through the expansion valve to adiabatically expand to a low temperature, and is sent to the dehumidifying heat exchanger 26. The refrigerant is blown from the inside of the water tank 4 through the exhaust port 12 through the exhaust duct 13. Dehumidify by cooling and condensing the humid air. The refrigerant passing through the dehumidifying heat exchanger 26 absorbs heat from the moist air and evaporates, becomes a low-temperature and low-pressure gas, and is sucked from the low-pressure side of the compressor 35 via the pipe 38. By continuing this cycle, the air dehumidified by the dehumidifying heat exchanger 26 can be heated by the heating heat exchanger 27.

  Pipings 36 and 38 that connect the compressor 35 to the dehumidifying heat exchanger 26 and the heating heat exchanger 27 extend in a direction substantially immediately above the compressor 35, are on the back side of the washing / drying machine main body 1, and are exhaust ducts. 13 is disposed along a corner on the side where the water supply means 10 on the substantially facing side is provided across the water tank 4, and the heat exchanger near the top from the compressor near the bottom of the washer / dryer body 1. Connected up to.

  In the structure of the washer / dryer in which the washing / drying capacity is increased as much as possible, the gap between the water tank 4 and the housing cover of the washer / dryer main body 1 is made small. The space formed by the back surface of 1 is insufficient for a unit configuration in which all the configurations of the heat pump cycle are arranged in one place.

  Here, in the present invention, the compressor 35, the dehumidifying heat exchanger 26, the heating heat exchanger 27, and the pipes 36 and 38 are all arranged in the same vibration system as the washing / drying machine main body 1 and separated from the water tank 4. Therefore, even if the pipes 36 and 38 are arranged close to or in contact with the inner surface of the housing cover of the washing and drying machine main body 1, they are separated from the vibration of the water tank 4 caused by the high-speed rotation of the drum 5 in the dehydration process. Therefore, vibration does not propagate and life reliability can be improved.

  Furthermore, since only the compressor 35 is provided below the water tank 4 of the base 3 and the diameters of the refrigerant pipes 36 and 38 are thin pipes of about 10 mm, the housing of the water tank 4 and the washing / drying machine main body 1 is provided. It is easy to provide it so as to pass through a slight gap between it and the body, and it is also possible to arrange it so as not to interfere with the water supply means 10 and connect it to the heat exchanger.

  Since only the thin pipes 36 and 38 are disposed across the upper and lower sides of the water tank 4 in the heat pump cycle as described above, the heat pump cycle is performed without increasing the depth and width of the washing / drying machine main body 1. Can be implemented. Since the height increases only because the heat exchangers 26 and 27 are provided on the upper surface, the installation area of the washing / drying machine main body 1 is not enlarged, so that there is no restriction on the installation location, which is convenient.

  The exhaust duct 13 sucks out humid air inside the water tank 4 from the exhaust port 12 in the vicinity of the bottom surface of the water tank 4, and is connected to a dehumidifying heat exchanger 26 provided above the water tank 4. In order to efficiently perform dehumidification or heating in the heat exchanger, it is desirable that the air flowing inside the heat exchanger is uniform and uniform. Here, the exhaust duct 13 is disposed in the space between the back surface of the water tank 4 and the drive motor 8 and the washing / drying machine main body 1 with a space that does not collide with the water tank 4 or the drive motor 8 even when the water tank 4 vibrates. Therefore, the size of the exhaust duct 13 is limited. On the other hand, in the lint filter 16 and the dehumidifying heat exchanger 26, since the area of the air flow path is larger than the area of the exhaust duct 13, the area of the exhaust duct 13 increases until reaching the inlet of the lint filter 16. However, even if the air flow path is expanded rapidly, the flow velocity is not uniformly reduced. Therefore, a portion with a high flow velocity and a portion with a low flow velocity are mixed, so the flow velocity of the air passing through the heat exchangers 26 and 27 is low. It is not uniform. By gradually expanding the area of the exhaust duct 13 from the lower exhaust port 12 to the upper heat exchangers 26 and 27 to suppress a sudden change in the area, the air passing through the heat exchangers 26 and 27 is reduced. This is preferable because it becomes more uniform.

  As shown in FIG. 3, heat exchangers 26, 27 are formed by providing a step in the upper part of the back surface of the washing / drying machine main body 1 from the exhaust duct 13 to the lint filter 16 to make it a notch 21. Even if the height is increased by mounting, the water faucet does not hit the main body 1 when the washing / drying machine is installed, which is more convenient. That is, it is desirable that the lint filter 16 and the heat exchangers 26 and 27 are not provided in the vicinity of the back surface of the washing / drying machine main body 1 but are shifted to the front to provide the notches 21.

  The outline of the movement of the garment 14 in the drying process inside the rotary drum 5 will be described with reference to FIG. A plurality of baffles 71, which are protrusions, are provided inside the cylindrical surface of the rotating drum 5. When the rotating drum 5 rotates (in FIG. 6, a state in which the rotating drum 5 is rotating in the clockwise direction), clothes are scraped up by the baffle 71 as indicated by an arrow 73, and then fall to the bottom surface of the rotating drum 5 by its own weight, It is stirred again by repeating the action of being picked up again by the baffle 71 and falling, and the evaporation of moisture from the clothes is promoted by blowing warm air between the clothes. At this time, hot air heated by the heating heat exchanger 27 is blown from the blowing port 23 provided in the vicinity of the upper side of the opening 6, exhausted from the exhaust port 12, dehumidified by the dehumidifying heat exchanger 26. .

  As described above, by directly blowing high-speed and high-pressure air blown from the blowing port onto the garment 14, moisture evaporation is promoted, and the garment 14 is agitated to stretch the wrinkles on the garment. This is convenient.

  FIG. 7 is a block diagram showing the configuration of the control system.

  The operation panel 110 is provided with various displays and various switches including a power source, and these are connected to the operation circuit 94. The switch selects execution of each process of washing, rinsing, dehydration, and drying, and each indicator displays the amount of detergent, the amount of water, or the time, progress, and abnormality of each process.

  FIG. 7 shows a control circuit section mainly composed of a microcomputer 100 (hereinafter referred to as a microcomputer) provided on the main control board 40. This functions as a control means for controlling the overall operation of the washing machine. The microcomputer 100 receives operation signals from various switches including the power switch of the operation panel 110. Then, the operation setting value corresponding to the user's operation signal, the amount of necessary detergent, the amount of water, or the time, progress state, abnormality, etc. of various processes are output to the respective displays or buzzers.

  The power supply circuit 95 directly rectifies and smoothes the commercial power supply, and supplies the DC power necessary for the microcomputer 100 and other circuits. For this reason, the DC power supply of the microcomputer 100 and other circuits is superimposed on the commercial AC power supply.

  The microcomputer 100 controls each motor-operated valve and each motor based on these input signals and a previously stored control program. The microcomputer 100 supplies the commercial power to the compressor 35, the main water supply valve 93, the softener water supply valve 89, and the drain valve 86 through each control circuit 96 to control the rotational speed of the compressor 35 or the opening / closing of the valve. Further, the microcomputer 100 controls the rotational speed of the fan motor 20 via the air blowing control unit 98 to vary the air volume. Further, the microcomputer 100 controls the rotation direction and the number of rotations of the drive motor (brushless motor) 8 that rotationally drives the drum 5 via the motor drive unit 99. The motor drive unit 99 increases the applied current by increasing the rotational load torque of the drive motor 8 to increase the drive torque, and decreases the applied current by decreasing the applied torque when the rotational load torque decreases. Control to keep the rotation speed constant. By detecting the current applied to the drive motor 8 in the motor drive unit 99, the magnitude of the load torque applied to the drive motor 8 can be determined, and the amount of cloth put into the drum can be detected. The detergent amount calculation unit 101 calculates a detergent amount necessary for washing based on the detected cloth amount.

  The temperature sensor 97 and the humidity sensor 90 detect the temperature and humidity of hot air used for drying clothes and send it to the main control board 40. The comparison unit 102 compares the measurement values obtained by the temperature sensor 97 and the humidity sensor 90 with a preset reference value 103 and outputs the magnitude of the reference value 103 to the microcomputer 100.

  Next, the operation of this embodiment will be described.

  First, an outline process of washing and drying in the washing / drying machine will be described. FIG. 8 shows a schematic flowchart of a standard course of the washing / drying machine. First, when the user turns on the power switch and the operation of the standard course is started, washing of the laundry, intermediate dehydration and rinsing twice, final dehydration, and drying are sequentially performed. First, the amount of laundry is detected (step S1), and then the user puts in detergent (step S20). After supplying the necessary tap water (step S2), washing (step S3) is performed and the washing water is drained (step S4). Thereafter, in order to squeeze out the detergent contained in the laundry, first intermediate dehydration is performed (step S5), and water supply is started again for the first rinse (step S6). When the first rinse (step S7) is completed, the rinse water is drained (step S8). Thereafter, in order to squeeze out the detergent still contained in the laundry, a second intermediate dehydration (step S9) is performed, and water supply is started again for the second rinse (step S10). When the second rinse (step S11) is completed, the rinse water is drained (step S12) and the final dehydration (step S13) is performed. Finally, drying (step S14) is performed, and washing and drying are completed.

Since the vibration of the water tank is not transmitted to the heat pump cycle, the life reliability is high and the depth of the apparatus can be reduced, so that a thin washer-dryer can be realized without increasing the installation area.

  In addition, warm air can be blown directly from the front of the aquarium to the clothes inside the drum, so drying of the clothes can be accelerated and the drying process can be completed in a short time, and high-pressure air can be blown directly onto the clothes at high speed. By attaching, it has the effect of extending the wrinkle of the clothes and improving the dry finish.
