  Hereinafter, examples according to embodiments of the present invention will be described with reference to the drawings. In addition, although the Example described below is a drum type washing dryer, this invention is applicable also to a drum type washing machine.

FIG. 1 is a perspective view of a drum type washing and drying machine according to an embodiment of the present invention.
The outer frame housing includes a housing body portion 21 and a base portion 1 that supports the housing body portion 21 so as to be placed thereon.

  The housing main body 21 includes substantially flat side surfaces 4, a rear surface 9, a substantially flat and rectangular front surface 2, a curved corner surface 5 positioned between the front surface 2 and both side surfaces 4, A laundry door 3 is provided at the center of the front surface 2 and can be opened and closed. The front surface portion 2 constitutes a first housing portion (front housing portion) that is provided with a laundry entrance door 3 and forms an outer surface on the front side of the outer frame housing. The curved corner surface portion 5 and both side surface portions 4 are A second casing part (side casing part) that is provided so as to recede from the side edge part of the first casing part and forms the outer surface of the side surface is configured.

  Further, the housing body 21 includes a curved upper surface portion 6, a lower curved corner surface portion 7, a concave ceiling surface portion 8, and a lower front surface portion 200 that is a part of the front surface portion 2. Since the ceiling surface portion 8 is concave, small items such as detergent can be temporarily placed. The substantially flat side surface portions 4 and the substantially flat front surface portion 2 may form curved surfaces having a curvature larger than that of the curved corner surface portion 5 in addition to the both side surface portions 4 and the front surface portion 2 being completely flat. . Moreover, you may have an unevenness | corrugation for improving an intensity | strength.

  It is easier to manufacture the side surface portion 4, the rear surface portion 9, and the front surface portion 2 into separate parts, but it is also possible to form each portion integrally as appropriate. For example, the two side surface portions 4 and the curved corner surface portion 5 may be formed as a single member, or the both side surface portions 4 and the rear surface portion 9 may be formed as a single member. However, when the strength of the side surface portions 4 is increased to form a structural member that also serves as a framework, it is advantageous to configure the structural member as a separate member from the curved corner surface portion 5 because of the thickness of the material and the plate material. Further, since the curved corner surface portion 5 is configured by a curved surface having a large curvature, it is advantageous to configure both the side surface portions 4 and the front surface portion 2 which are flatter than the curved corner surface portion 5 as separate members. In any case, the boundary between the front surface portion 2 and the curved corner surface portion 5 is not determined only by the boundary of the members, and in the case of an integrally molded material, the hue is considered in consideration of the effect of the present invention. Specified by the boundary of curvature and the degree of curvature change.

A plurality of lower handles 14 are provided at the lower part of each side surface 4 for carrying the main body, and an upper handle 15 is provided at the upper side. In particular, the upper handle 15 is positioned on the rear side of the front open type drum-type washing and drying machine having the door 3 on the front side, because the heavy driving unit is on the rear side.

  A drain hose 16 for draining washing water is attached to the base portion 1, and a hose attachment hole 17 for fixing the hose 16 is provided. In addition, mounting legs 18 are provided at the four corners of the base portion 1. The mounting legs 18 are made of rubber and dampen vibration during operation of the drum type washing and drying machine.

  A push button switch 19 for opening the entrance door 3 is provided in the upper right part of the front part 2, and a lint filter 20 for collecting the lint of the laundry is provided in the lower front part 200.

  The outer frame casing has the casing main body 21 and the base 1, but the base leg 1 may not be provided, and the mounting legs 18 may be provided on the casing main body 21. In this case, the housing body is an outer frame housing.

  2 and 3 relate to the embodiment of the present invention and show a longitudinal sectional view and a transverse sectional view of a drum type washing machine.

An outer tub 22 is provided on the inner side of the casing main body portion 21 constituting the entire outer shell portion. A plurality of suspensions 23 are provided in the lower part of the outer tub 22 to support the outer tub 22 from below. Further, the upper part of the outer tub 22 is supported by two tension springs 24 and 25 arranged at the front and rear.

The suspension 23 supports the outer tub 22 and the attached total weight, and has a strong structure. In addition, a damping mechanism or the like is provided for preventing abnormal vibration caused by resonance of the outer tub 22 that occurs during dehydration operation. In addition, the tension springs 24 and 25 supported from the upper part of the outer tub 22 are provided for the purpose of preventing the outer tub 22 from collapsing in the front-rear direction and for reducing vibrations in the front-rear, vertical and horizontal directions during dehydration. ing.

  At the time of washing and rinsing, water necessary for washing and rinsing is supplied via a water supply hose 26 connected to a water tap, a water injection hose 28 connected to a water supply electromagnetic valve 27, and the detergent tray 10.

  The supplied water is stored as washing water at the bottom of the outer tub 22 and as rinsing water at the time of rinsing. A detergent necessary for washing is put into the detergent tray 10, and a softening finish is put into the detergent tray 10 to improve the finish. At the time of washing, water supplied from the water injection hose 28 is poured from the upper part of the outer tub 22 through the flexible hose 29 while dissolving the detergent in the detergent tray 10.

  The laundry 31 is placed in the rotating drum 30 inside the outer tub 22 by opening the door 3. The direction of the axis of rotation of the rotating drum is horizontal. This means that it is different from a vertical washing machine having a rotation axis centered in a vertical direction. In this case, the rotation axis may be horizontal, or includes a state in which the rotation axis is inclined from the horizontal so that the rear side is lower than the front side.

  A fluid balancer 32 is provided on the outer periphery of the opening of the rotating drum 30 to reduce unbalanced vibration caused by the laundry 31 during dehydration.

  Water that has become unnecessary after washing and rinsing and water that has been dehydrated from the laundry 31 during dehydration are drained from the drain hose 16 by opening the drain valve 39.

  At the time of drying, the air blown by the blower fan 40 passes through the inside and the outer periphery of the rotating drum 30 containing the laundry 31 and contains lint. For this reason, it blows to the heater 41 via the drying filter 11, and the heated warm air is blown into the rotary drum 30 from the opening 42 provided in the upper part of the outer tub.

The hot air passes through the laundry 31 and is dehumidified from the rear part of the rotary drum 30 through the ventilation port 44 of the dehumidifying device 43 provided at the bottom of the outer tub 22, and is repeatedly circulated by the blower fan 40 to dry the laundry 31. . Further, the depth dimension of the rotating drum 30 is indicated by L, and the diameter dimension is indicated by P.

Next, the main part of the present invention will be described with reference to FIGS.
FIG. 4 is a front view of the drum type washing and drying machine as seen from the front.
The drum-type washing / drying machine has an imaginary line X across the front side of the outer frame housing, where the diameter of the door 3 is D, the width of the front face 2 is Wi, and the width of both sides 4 is Wo. The dimension width A of the curved corner surface portion 5 and the dimension width B of the front surface portion 2 have a relationship of A = (Wo−Wi) / 2 and B = (Wi−D) / 2.

  Note that the imaginary line X is provided on the condition that the center of the entrance door 3 is traversed when the entrance door 3 has a circular shape. It shall pass through the position. Each dimension is an external dimension, and is measured by a portion exposed to the outside of the apparatus in a state where the doorway 3 is closed.

  Since the curved corner surface portions 5 are provided on both ends of the outer frame housing, the boundary with the side surface portions 4 is not clear and blurs, so the front surface portion 2 is emphasized and the width of the outer frame housing of the drum type washing and drying machine is increased. The effect of appearing narrow becomes larger. Due to the effect that the lateral width of the outer frame casing appears to be narrow, the problem that the room feels narrow is eliminated.

  Further, the curved corner surface portion 5, the curved upper surface portion 6, and the lower curved corner surface portion 7 form a curved surface around the outer frame housing. For this reason, the ridgeline bordering the outer frame casing is blurred and the front surface portion 2 is emphasized, and the curved surface surface section coefficient is increased by the curved surface, the mechanical strength is increased, and noise due to vibration can be reduced.

  In the case of the present embodiment, the width Wo of both sides of the both side surface portions 4 and the diameter D of the entrance door 3 are determined by the diameter of the rotary drum installed in the outer frame housing. For this reason, by increasing the A dimension width, the B dimension width is decreased, and the ratio of the diameter D of the entrance door 3 to the width dimension Wi of the front surface portion 2 is increased.

  In other words, in the height direction position where the width direction dimension of the entrance door 3 is the maximum, the width direction dimension (component) A on the appearance occupied by the curved corner surface part 5 and the curvature provided on both sides of the front surface part 2 respectively. A width direction dimension (component) B on the appearance occupied by the front surface portion 2 between one curved corner surface portion 5 of the corner surface portions 5 and the edge of the door 3 on the curved corner surface portion 5 side is such that A> B. I tried to be a relationship.

  Furthermore, in other words, in the width direction dimension at the height direction position where the width direction dimension of the doorway 3 is maximized, the width direction dimension (component) that the second casing part constituted by the curved corner surface part 5 and both side surface parts 4 occupies. ) A and a width direction dimension (component) B occupied by the first housing portion between the side edge portion of the first housing portion and the edge of the door 3 that is located on the side edge portion side, A> B relationship was established. When the side surface portions 4 are formed only by flat surfaces having no curved surface, the width direction dimension (component) A occupied by the second housing portion is formed only by the curved corner surface portions 5.

  By satisfying the condition of A> B, the ratio can be made smaller and the entrance door 3 can be seen larger. The entrance / exit door 3 looks large, so it looks good and is easy to use.

  In this embodiment, since Wi = 553 (mm), Wo = 695 (mm), and D = 480 (mm), A = 71 (mm), B = 36.5 (mm), and A> B. Yes.

  In order to make the lateral width of the outer frame casing appear to be small, it is necessary to emphasize the front surface portion 2. For this reason, the effect is further increased by changing the hue of the curved corner surface portion 5 located on the side surface portion of the front surface portion 2.

  Even if the saturation and brightness are changed in addition to the hue, the same effect can be obtained although it is less than in the case of the hue. If the brightness and saturation are reduced, it approaches black, and if it increases, it approaches white. Therefore, if the difference between these values is 20% or more, there is clearly a significant difference visually.

  In this embodiment, the curved corner surface portion 5 on both sides and the lower curved corner surface portion 7 are the same color, differing from the hue of the front surface portion 2, and the saturation and lightness of the front surface portion 2 are reduced by making the front surface portion 2 smaller. The part is more emphasized. As a result, the width of the outer frame casing can be seen to be small.

  In addition, since the lower curved corner surface portion 7 and the curved corner surface portion 5 are formed so as to be continuous, it is a clean and well-organized design with a sense of unity. By making the same color up to the lower curved corner surface portion 7, the height direction also appears small, and the entire drum type washing / drying machine looks compact.

  In order to clarify the effect of this embodiment, the condition of P / 2> L is satisfied, where P is the diameter of the rotary drum installed and L is the depth dimension. That is, the effect becomes more significant in a drum-type washing / drying machine having a large diameter rotating drum. In this embodiment, P = 600 (mm) and L = 293 (mm).

  Since the lateral width of the outer frame housing is apparently seen when viewed from the front of the front portion 2, it is necessary to make the dimension width B of the front portion 2 as small as possible in order to make the entrance door 3 appear larger. When the dimensions of the rotating drum are determined, the configuration of the outer frame casing is determined only by the dimension between (A + B) because the width dimension Wo on both sides of the both side surface portions 4 and the diameter D of the doorway 3 are determined. In the present embodiment, among the dimensions between (A + B), by increasing the dimension of A and decreasing the dimension of B, the lateral width of the drum type washing machine body appears to be apparently small, so that the doorway is made larger. I made it.

The size of the entrance / exit door 3 is relatively larger as the ratio of the width Wi of the front surface portion 2 to the diameter D of the entrance / exit door 3 is closer to 1, so this ratio K = Wi / D is
1 <K <1.2
It is good to take within the range.

The hinge of the entrance door 3 will be described with reference to FIG.
The door 3 has a hinge arm 50 at one end on the back side. The tip of the hinge arm 50 is rotatably supported by a hinge support shaft 52 provided on the front reinforcing plate 51. The hinge arm 50 has a curved shape that turns around more than a semicircle. The hinge support shaft 52 is provided so as to be located on the back side of the front portion 2 at the dimension width B. Therefore, the hinge support shaft 52 is provided inside the outer frame housing, and the hinge arm 50 is positioned so as to be hidden in the outer frame housing when the door 3 is closed, and as the door 3 is opened. It has a structure that protrudes to the outside of the outer frame housing.

  The end portion 53 of the hinge arm 50 is located between the dimension width A and the dimension width B (between the curved corner surface portion 5 and the front surface portion 2) in the illustration of FIG. When the door 3 is closed, the end portion 53 moves to the back side of the curved corner surface portion 5 beyond the dimension width A and the dimension width B.

  In this manner, the door 3 can be rotated by a hinge having a hinge support shaft provided inside the outer frame housing and a hinge arm having a curved shape supported rotatably on the hinge support shaft. In the state where the doorway 3 is closed, the hinge arm 50 moves to the back side of the curved corner surface portion 5 beyond the width direction dimension range of the appearance occupied by the front surface portion 2. A drum-type washing / drying machine having a configuration in which the entrance / exit door 3 can be seen larger with a dimension width B narrower than the dimension width A interposed between the curved corner surface portion 5 and the entrance / exit door 3 can be realized.

1 is a perspective view of a drum type washing and drying machine according to an embodiment of the present invention. FIG. 2 is a cross-sectional view of a drum type washer / dryer according to an embodiment of the present invention. The longitudinal cross-sectional view of the drum type washing-drying machine which concerns on the Example of this invention is shown.
