  FIG. 2 is a diagram for explaining the configuration around the drum 10, the suspension 7, and the base plate 40. For easy understanding, the periphery of the drum 10, the suspension 7 and the base plate 40 of the drum type washing machine 100 is illustrated. It is the figure which extracted and drew. In FIG. 2, the left and right are symmetrical structures and have the same structure. Here, the structure of the left suspension 7 will be described.

  As shown in FIG. 2, the suspension 7 includes, for example, an oil damper mechanism 22 and a compression coil spring 23. The oil damper mechanism 22 includes a cylinder 24 filled with oil and gas, and a piston rod 25 having one end inserted into the cylinder 24. The compression coil spring 23 is wound around the lower half of the piston rod 25 and is stretched between the upper spring seat 26 and the lower spring seat 27. Screw portions 24 a and 25 a are formed at the upper end of the cylinder 24 and the lower end of the piston rod 25, and are fastened by a nut 31.

  The suspension 7 is inserted at its upper end with a seat plate 28a, a vibration-proof cushion 29a, a mounting plate 30, a vibration-proof cushion 29b, and a seat plate 28b in this order, and then fastened with a nut 31 to the protruding screw portion 24a. The whole is fixed by doing. The attachment plate 30 is elastically attached and fixed to the water tank 6 at the upper end of the suspension 7 by tightening screws 32 to bosses 6 a provided at a plurality of locations below the water tank 6.

  The suspension 7 has a seat plate 33a, an anti-vibration cushion 34a, a support plate 42a, an anti-vibration cushion 34b, and a seat plate 33b inserted in this order at the lower end portion, and then a nut 31 is fastened to the protruding screw portion 25a. The whole is fixed by fastening. The support plate 42a is, for example, a metal fitting for mounting and fixing the suspension 7, and has screw holes for fixing to the base plate 40 (the same applies to support plates 42b, 42c, and 42d described later).

  The support plate 42 a is fixed to a base portion 41 provided on the base plate 40 with screws 36, whereby the lower end portion of the suspension 7 is elastically attached and fixed to the base plate 40. If the base portion 41 provided on the base plate 40 and the support plate 42a are regarded as an integrated support base 43a, it can be seen that the suspension 7 is supported and fixed by the support base 43a.

  FIG. 3 is an enlarged view of the periphery of the lower mounting portion of the suspension 7 of FIG. Although only the left side is illustrated, the right side has the same structure, and thus illustration and description thereof are omitted. The support plate 42 a is fastened and fixed to the reinforcing member 440 with screws 36 on the base portion 41. The reinforcing member 440 extends obliquely downward to the right from the base portion 41 and is fixed on the base plate 40 with screws 46.

  The reinforcing member 440 includes a parallel part 440a parallel to the upper part of the base part 41, a parallel part 440c parallel to the base plate 40, and an oblique part 440b positioned between the parallel part 440a and the parallel part 440c. The reinforcing member 440 may be a member having a plate shape, for example, or may be a member having a bar shape or a square shape. Moreover, a material such as synthetic resin or metal (for example, stainless steel) can be adopted as necessary.

  The reinforcing member 440 is disposed and attached at a position including a location close to the attachment position of the suspension 7. The support plate 42 a is fastened together with the reinforcing member 440 and the screw 36 at the upper portion of the base portion 41. The other end of the reinforcing member 440 is fixed to the base plate 40 with a screw 46. The reinforcing member 440 is more firmly fixed on the base plate 40 and the base portion 41 by the parallel portions 440a and 440c.

  According to the configuration described above, the reinforcing member 440 forms a triangular structure, that is, a truss structure, by the base portion 41 and the base plate 40. As a result, the structure around the support plate 42a to which the suspension 7 is attached is strengthened structurally, and the amount of elastic deformation of this portion can be reduced. As a result, the support plate 42a is firmly fixed, and even if the suspension 7 vibrates in the horizontal and horizontal directions, the support plate 42a is reduced from moving along with it, and vibration energy is reliably prevented from vibration. It can be absorbed by the cushions 34a, 34b.

  Accordingly, it is possible to effectively improve the vibration reduction effect by the vibration-proof cushions 34a and 34b, and thereby, for example, it is possible to effectively suppress horizontal and horizontal vibrations such as a plowing motion. As described above, in the present embodiment, the reinforcing member 440 for suppressing the elastic deformation of the support plate 42a and its periphery is added to the support plate 42a, and the movement of the support plate 42a is effectively suppressed.

  Further, the reinforcing member 440 is disposed and attached at a position close to the suspension 7 attachment location. Thereby, since the suspension 7 and the support plate 42a can be more directly and firmly fixed, vibrations in the horizontal and horizontal directions can be more effectively suppressed. As described above, the vibration of the drum type washing machine 100 as a whole becomes low vibration, and as a result, the dewatering performance of the drum type washing machine 100 can be improved.

(Second Embodiment)
Next, a second embodiment will be described. FIG. 4 is an enlarged view of the attachment portion at the lower part of the suspension 7 of the drum type washing machine 100 according to the second embodiment. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. Although only the left side is illustrated, the right side has the same structure, and thus the description on the right side is omitted.

  As shown in FIG. 4, in the second embodiment, the support plate 42 b and the reinforcing member 441 are integrally formed as one component, and are fixed to the base plate 40 and the base portion 41 by screws 36 and 46. Yes. Similar to the first embodiment, the reinforcing member 441 includes a parallel portion 441a, an oblique portion 441b, and a parallel portion 441c, and the base plate 40, the base portion 41, and the reinforcing member 441 (oblique portion 441b) constitute a truss structure. doing.

  In the present embodiment, a reinforcing member 440 that suppresses elastic deformation around the support plate 42 is added to the support plate 42b to effectively suppress the movement of the support plate 42b. If the base 41 provided on the base plate 40 and the support plate 42b are regarded as an integrated support base 43b, it can be seen that the suspension 7 is supported and fixed by the support base 43b.

  According to the above configuration, the same effect as in the first embodiment can be obtained. Furthermore, since the support plate 42b and the reinforcing member 441 are integrally formed, more lateral vibration is reliably reduced without transmission loss. Thereby, the drum-type washing machine 100 becomes a low vibration and can aim at the improvement of dehydration performance. In addition, since the support plate 42b and the reinforcing member 441 are integrated, it is possible to reduce the time and labor required for assembly of the drum type washing machine 100, and the productivity is excellent.

(Third embodiment)
Next, a third embodiment will be described. FIG. 5 is a diagram for explaining the configuration around the lower part of the drum 10 and the suspension 7. Similarly to FIG. 2, for easy understanding, the drum 10, the suspension 7, and the base plate 40 of the drum type washing machine 100 are illustrated. It is the figure which extracted the periphery and was drawn. The same components as those in the first and second embodiments are denoted by the same reference numerals, and description thereof is omitted.

  As shown in FIG. 5, in the third embodiment, the support plates 42 c of the suspension 7 provided on the left and right are connected and fixed so as to be passed by a reinforcing member 500. The reinforcing member 500 may be a member having a plate shape, for example, or may be a member having a bar shape or a square shape. Moreover, a material such as synthetic resin or metal (for example, stainless steel) can be adopted as necessary.

  The reinforcing member 500 is disposed and attached at a position including a location close to the attachment position of the suspension 7. The support plate 42 c is fastened together with the reinforcing member 500 and the screw 36 at the upper portion of the base portion 41. Similarly, the other end of the reinforcing member 500 is fixed to a support plate 42c and a base 41 provided at the lower part of the right suspension 7 in the drawing.

  FIG. 6 is an enlarged view of the configuration around the lower portion of the left suspension 7. Since the right suspension 7 has the same structure, illustration and description thereof are omitted. The reinforcing member 500 has a portion 500a at the left end where the portion fixed on the base portion 41 is thin. The part other than the part 500a is a thick part 500b, and the reinforcing member 500 is composed of the parts 500a and 500b.

  In the portion 500a, the reinforcing member 500 has a screw hole. Similarly, the support plate 42c has screw holes. The support plate 42c and the reinforcing member 500 are fastened and fixed to the base portion 41 with screws 36 at this portion. If the base part 41 provided on the base plate 40 and the support plate 42c are regarded as an integrated support base 43c, it can be seen that the suspension 7 is fixed to the support base 43c.

  With this configuration, the left and right support plates 42c are connected and fixed by the reinforcing member 500. Thereby, the reinforcing member 500 functions as a beam, and the left and right support plates 42c can be firmly fixed, resulting in a structurally reinforced structure. In the present embodiment, a reinforcing member 500 that suppresses elastic deformation around the support plate 42c is added to effectively suppress the movement of the support plate 42c. Accordingly, since the amount of elastic deformation at this portion can be reduced, the vibration reduction effect of the vibration-proof cushions 34a and 34b can be effectively improved. Thereby, for example, vibrations in the horizontal direction and the horizontal direction such as a plowing motion can be effectively suppressed.

  Further, according to the above configuration, one of the reinforcing members 500 is fastened and fixed together with the support plate 42 c to the base portion 41, so that the reinforcing member 500 is not fixed to the bottom surface portion of the base plate 40. Thereby, since the path | route which transmits a vibration to the baseplate 40 reduces, the vibration of the baseplate 40 can be reduced. As described above, the vibration of the drum type washing machine 100 as a whole becomes low vibration, and as a result, the dewatering performance of the drum type washing machine 100 can be improved.

  In the third embodiment, the support plate 42c under the left and right suspensions 7 is connected and fixed by the reinforcing member 500. However, one is configured as described above, and the other is fixed to, for example, the horizontal wall portion of the base plate 40. It is good also as forming the structure for this and fixing the reinforcement member 500 to this.

Although only the left side is illustrated, the right side has the same structure, and thus illustration and description on the right side are omitted.

  As shown in FIG. 7, in the fourth embodiment, the support plate 42 d and the reinforcing member 501 are integrally configured as one component, and are fixed to the base portion 41 with screws 36. Similar to the third embodiment, the reinforcing member 501 has portions 501a and 501b.

  In the present embodiment, a reinforcing member 501 that suppresses elastic deformation around this is added to the support plate 42d to effectively suppress the movement of the support plate 42d. If the base portion 41 provided on the base plate 40 and the support plate 42d are regarded as an integrated support base 43d, it can be seen that the suspension 7 is fixed to the support base 43d.

  According to the above configuration, the same effect as that of the third embodiment can be obtained. Furthermore, since the support plate 42d and the reinforcing member 501 are integrally formed, vibration in the lateral direction is further reduced. Thereby, the drum-type washing machine 100 becomes a low vibration and can aim at the improvement of dehydration performance. In addition, since the support plate 42d and the reinforcing member 501 are integrated, it is possible to reduce the time and labor required for assembly of the drum type washing machine 100, and the productivity is excellent.
