  In a drum-type washing and drying machine, for the purpose of improving the finishing performance at the time of drying and saving energy, the hot air volume is increased and the wind speed is increased. By the way, the hot air outlet is provided in the outer tub, and the direction of the hot air is changed at the outlet in order to improve the drying efficiency. For this reason, the fluid force resulting from the warm air acts on the outer tub to vibrate the outer tub, which has a problem of causing noise generation. As a result, when quietness is required, there is a problem that the wind speed cannot be increased. As a result, there is a problem that the drying power is reduced and the drying time is extended. In addition, there is a problem that the finish is also deteriorated.

  Also, in the drum type washing and drying machine, for the purpose of increasing the capacity, improving the finishing performance and saving energy, the diameter of the washing and dewatering tank is increased and the speed of dewatering rotation is increased. By the way, the size of the housing is restricted due to the installation property. Accordingly, the diameter of the outer tub is inevitably limited, and the increase in the diameter of the washing / dehydration tub enclosed in the outer tub is accompanied by the narrowing of the gap between the outer tub and the washing / dehydration tub. It becomes. Moreover, in the drum type washing / drying machine in which the washing / dehydrating tub rotating shaft is substantially horizontal, a concave drainage groove long in the direction of the rotation center axis is provided on the inner vertical lower side of the outer tub. As a result, there is a problem that the fluid force resulting from the rotation of the washing and dewatering tub acts on the drainage groove when the washing and dewatering tub rotates at a high speed, causing noise generation. As a result, when silence is required, there is also a problem that the speed of dehydration rotation cannot be increased. As a result, there is a problem that the dehydration power is reduced, and the dehydration time is extended and the drying time is extended.

  A second object of the present invention is to provide a drum-type washing and drying machine that achieves a reduction in fluid force by reducing the shape of the drainage groove, achieves low noise, achieves high capacity, has good finish and saves energy. It is to provide.

In order to achieve the first object, the present invention provides a washing and dewatering tub for storing clothes, an outer tub that encloses the washing and dewatering tub, a housing that supports the outer tub, and the washing and dewatering tub.

In order to achieve the second object of the present invention, a washing and dewatering tub having a drain hole for dehydration, an outer tub having a drainage groove containing the washing and dehydrating tub and connected to a drain outlet, In a drum-type washing and drying machine including a casing that supports an outer tub and a driving unit that drives the washing and dewatering tub,
A drum-type washing / drying machine characterized in that an upstream side of the rotation of the washing and dewatering tank, which is one side of the drainage groove, is inclined to the downstream side.

  According to the above means, the vibration generated in the hot air outlet due to the fluid force generated during the blowing is suppressed by the cushioning material from being transmitted to the tank cover, and the vibration of the outer tank, which is a large sounding body, is reduced. The vibration noise can be reduced. In addition, since vibration transmission from the tank cover to the main body tank is also suppressed, vibration is reduced and vibration noise is reduced.

  In addition, the air flow in the drainage groove due to the rotation of the washing / dehydration tank during the dehydration operation is prevented from being disturbed and the fluid noise is reduced by the inclination of the upstream side surface of the drainage groove and the shape of the saddle on the downstream side. Further, the vibration generated in the bag due to the air flow is suppressed from being transmitted to the tank by the buffer material, so that the vibration of the outer tank, which is a large sound generator, is reduced, and the vibration noise is reduced.

  In the drum type washing and drying machine of the present invention, for the purpose of increasing the capacity, improving the finishing performance during drying, and saving energy, the drum diameter is increased, the dehydration speed is increased, and the hot air volume is increased. Wind speed has been increased.

  In the present washing machine characterized in that high-speed wind is directly applied to the clothes and wrinkles generated in the clothes are stretched by the force of the wind, the blower unit 28 that generates high-speed wind and the warm air that directly applies the wind to the clothes The blowout port 32 is required. Details of the hot air outlet 32 will be described with reference to FIGS. 6 is a front view of the outer tub cover 2d of the hot air outlet 28 installation portion, and FIG. 7 is a cross-sectional view of the hot air outlet 32 cut along a two-dot chain line AA in FIG.

  The hot air outlet 32 is fastened from the front side of the outer tank cover 2d along the opening 2c via a cushioning material 32e made of an elastic body or the like, and flow paths 32b and 32c are formed inside. A bellows pipe joint 30b is attached to the inlet of the hot air outlet 32, and a nozzle 32d is formed at the outlet 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 to be substantially the same so that clothing does not enter between the gap between the washing / dehydration tub 3 and the outer tub cover 2d. Yes. The outlet 32a of the hot air outlet 32 is formed so as to protrude inward from the inner peripheral surface of the opening 2c, and the nozzle 32d opens toward the washing and dewatering tub 3 so that The warm air hits the clothes in the washing / dehydrating tank 3 directly.

  The flow of wind during the drying operation is as follows. When the blower unit 28 is operated and the heater 31 is energized, high-speed warm air blows into the washing and dewatering tub 3 from the nozzle 32d (arrow 41), hits the wet clothing, warms the clothing, and moisture evaporates 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 nozzle 32d so that high-speed warm air directly hits the garment.

  In general, the main sounding body of noise in a washing machine is the outer tub 2, and the interruption of vibration transmission to the outer tub 2 is an effective means for noise reduction. As described above, the vibration generated in the blower unit 28 is fortunately suppressed from being transmitted to the outer tub 2 by the connection configuration via the bellows pipe joint 30b. However, the direction of the flow of the wind is changed at the hot air outlet 32, and the hot air outlet 32 is vibrated by the pulsating pressure of the wind.

  In the present invention, the hot air outlet 32 is configured to be fastened to the outer tub cover 2d through a cushioning material 32e made of an elastic body or the like, so that the hot air outlet 32 is generated by the pulsating pressure of the wind. The function which absorbs the vibration which performed and suppresses the vibration transmission to the outer tank cover 2d is made to work.

  By the way, in this washing machine characterized by large capacity and energy saving, the diameter of the washing and dewatering tank 3 is increased and the speed of dewatering rotation is increased. At this time, the size of the housing 1 is restricted due to the installation property. Accordingly, the diameter of the outer tub 2 is inevitably limited, and the increase in the diameter of the washing / dehydrating tub 3 contained in the outer tub 2 reduces the gap between the outer tub 2 and the washing / dehydrating tub 3. Will be accompanied. As a result, the effect of the fluid force of the gap flow caused by the rotation of the washing and dewatering tub 3 on the outer tub 2 is increased. In addition, as described above, in the present washing machine, the concave drainage groove 45 that is long in the direction of the central axis of rotation is provided on the inner vertical lower side of the outer tub 2, so that the fluid force during high-speed rotation is The drainage groove 45 is worked.

It is a bond. On the downstream side, a basket 45b projecting toward the upstream side is provided, and the tip of the basket 45b has a round shape that is not an edge, and the center of rotation of the washing and dewatering tub 3 has a projecting length that covers about half of the drainage port 2b. The configuration has a feature of having a skew angle 45e of about 10 degrees with respect to the axis. The function of the skew angle 45e is maintained even if the skew angle 45e is in the opposite direction to the figure.

  In the present invention, the pressure difference is suppressed by changing the gap between the outer tub 2 and the washing / dehydrating tub 3 steplessly on the upstream side, and the phase of the fluid force is changed by providing the skew angle 45e on the downstream side. In this way, the working fluid force is distributed to suppress the generation of fluid noise and the two functions to suppress the acting fluid force.

The central portion of the axial length is characterized by having a feature in the vicinity of the convex tip on the upstream side.

  In the present invention, the pressure difference is suppressed by changing the gap between the outer tub 2 and the washing / dehydrating tub 3 in a stepless manner on the upstream side, and the phase of the fluid force is adjusted by making the central portion convex on the downstream side. By changing the distribution, the working fluid force is distributed to suppress the generation of fluid noise and the two functions of suppressing the acting fluid force.
