[Industrial applications]

  The present invention relates to a drum type washing machine.

[0002]

[Prior art]

  An outline of a conventional drum type washing machine of this type is shown in FIGS.   A water tank 3 suspended by a spring 2 on an outer tank 1 is supported horizontally and is rotatable. The interior of the ram 4 is equipped with a plurality of pairs of inverted shock absorbers 5 (outer chutes) on the bottom. (Insert the inner tube from the lower end of the bracket) There is.

[0003]   Legs 8 are attached to the four corners on the rear surface side of the bottom table 7 which is joined to the lower end of the outer tank 1 (screws). Etc.), and a plurality of strip-shaped reinforcing plates 9 for reinforcing the base 7 are attached between the legs 8 on the surface side. Have been installed (screws, etc.).   The other end of the shock absorber 5 is pivotally attached to the reinforcing plate 9 by a screw pin 6.

[0004]   Therefore, when the drum 4 rotates at high speed during washing and dehydration operations, it is stored in the drum 4. Vibration of the aquarium 3 due to uneven displacement of the laundry is damped by the spring 2 and the shock absorber 5. However, the reinforcing plate 9 receives the force in the direction of the arrow via the shock absorber 5 due to this damping action. The flexure between the legs 8 of the base 7 having the legs 8 as fulcrums is suppressed.

[0005]   In addition, as shown in FIG. 7, the reinforcing plate 9 is formed in the depth direction of the base 7 having a short span between the legs 8. However, depending on the amount of bending of the base 7, it may be necessary to attach it. It

[0006]

[Problems to be solved by the device]

  As described above, the bottom stand 7 of the conventional drum type washing machine has a belt for suppressing the bending. The reinforcing plate 9 is provided, and the grounds are as follows. That is, drum washing From the standpoint of installation of the rinsing machine and stability of vibration, etc., the legs 8 of the base 7 may be provided at the four corners. Many.   Therefore, the other end of the shock absorber 5 is attached to the surface side of the base 7 corresponding to the vicinity of the leg 8. By doing so, it is not necessary to install the reinforcing plate 9, but to the bottom stand 7 of the shock absorber 5. The mounting part of the water tank 3 inside the washing machine, other parts (motor, drain valve, etc.) Can be provided at a position corresponding to the vicinity of the leg 8 in consideration of the damping action direction of the shock absorber 5 and the like. It is often the case that the flaw must be placed inside the legs 8 at the four corners.

[0007]   As described above, since it is necessary to install the strip-shaped reinforcing plate 9, there are restrictions on the arrangement of other parts. There is an inconvenience that the cost is increased as well as it is exerted.   In addition, when the base 7 is made of synthetic resin, stronger reinforcement is required. However, it had a great impact on cost.

[0008]   In view of such a situation, the present invention suppresses the bending of the base without requiring a belt-shaped reinforcing plate. The purpose is to provide a drum type washing machine that can be controlled.

[0009]

[Means for Solving the Problems]

  In order to achieve the above-mentioned object, the present invention provides a drum for washing and dehydrating, and a drum The interior of the outer tank is hung from the outer tank via a spring, and it is placed on the bottom surface of the outer tank. A drum-type washing machine consisting of a water tank supported by a shock absorber with the end attached And install a washing machine on the back side of the bottom table near the one end mounting position of the shock absorber. The reason is that a protrusion that comes into contact with the floor is provided.   Then, the protrusion may be attached to the base or formed integrally with the base.   In addition, it is preferable to attach an elastic body in contact with the installation floor surface to the tip of the protrusion.   In addition, the height of the protrusion with an elastic body attached to the tip can be adjusted so that it touches the floor. Can also be

[0010]

[Action]

  The shock absorber is attached to the protrusion on the rear side of the bottom that is near the shock absorber mounting position. The force associated with the vibration action is directly applied to suppress the bending of the base.   Further, the elastic body mounted on the protrusion assists the damping effect of the shock absorber.   Then, adjust the height of the protrusion with the elastic body installed from the floor surface, and It can be installed stably depending on the convexity and inclination.

[0011]

【Example】

  An embodiment of the present invention will be described with reference to the drawings.   The same parts as those in the conventional example are designated by the same reference numerals.   As shown in FIGS. 1 and 2, the water tank 3 suspended from the outer tank 1 by the spring 2 is The drum 4 which is supported flat and rotatable is installed inside, and the bottom of the drum 4 has a plurality of inverted pairs. One end of a shock absorber 5 of the mold is pivotally attached by a screw pin 6.

[0012]   Then, on the surface side of the bottom stand 7 that joins with the lower end of the outer tub 1, the buffer 5 A support metal fitting 10 pivotally attached to the end by a screw pin 6 is attached by a screw or the like, and On the back side, legs 8 are attached to the four corners (screws, etc.) of the metal fitting 10 and At a portion corresponding to the vicinity of the mounting position (including directly below), the protrusion 11 that contacts the floor surface of the washing machine is the bottom. It is formed integrally with the table 7.   As shown in FIG. 3, the protrusion 11 has a cross-shaped rib in the inner cavity of the cylindrical outer cylinder 11a. 11b is integrally formed to increase rigidity.   The protruding portion 11 has a flange portion formed on the outer cylinder 11a, and the flange portion is attached to the bottom base 7 with a screw or the like. May be attached.   Further, the support metal fitting 10 has sufficient strength to support the force associated with the vibration damping action of the shock absorber 5. Has a minimum size required from the standpoint of installation space on the base 7 and cost. The width of the base 7 is not the same as the conventional strip-shaped reinforcing plate 9. .

[0013]   When the laundry is stored in the drum 4 for washing and dehydration operation, The vibration of the water tank 3 acting as a vibrating body is suppressed by the spring 2 and the shock absorber 5. The force via the shock absorber 5 at the time of It is transmitted to the installation floor surface from the protrusions 11 provided in the vicinity, and the bottom stand 7 is not bent or flexed. Suppress life.

[0014]   FIG. 4 shows another embodiment of the protruding portion, in which an elastic material such as rubber is provided below the protruding portion 12. The elastic body 13 absorbs the vibration transmitted from the protrusion 12 to the installation floor surface. It was designed to fit.

[0015]   FIG. 5 shows still another embodiment of the protrusion, in which the elastic body 1 such as rubber is attached to the lower end. 4 is inserted from below the protrusion 16 into the screw hole of the support fitting 10. A lock nut 17 that is screwed and joined to the lower end of the protrusion 16 is fastened to the screw rod 15. It is a thing.   Therefore, after adjusting by rotating the screw rod 15 for unevenness and inclination of the installation floor surface, The position is fixed by the lock nut 17, and stable installation without rattling can be performed. .

[0016]

[Effect of device]

  The present invention has a protrusion on the back surface of the bottom base corresponding to the vicinity of the shock absorber mounting position on the front side of the bottom base. Since it is provided, it is possible to effectively suppress the occurrence of bending of the base, and the base is deformed and damaged. It is possible to reduce the cost while preventing the above.   Also, since an elastic body is attached to the tip of the protrusion, vibration to the installation floor can be reduced. You can   In addition, the height of the protrusion from the installation floor can be adjusted, so the unevenness of the installation floor Also, stable installation is possible even with inclination.
