- shrinks and the other expands, but since there is no restriction on the direction of extension, when the dehydration tank mortar shakes violently, the upper end of the dehydration tank - collides with the inner surface of the dehydration outer tank mortar. This has a habit of causing damage and accidents.

The present invention aims to address this problem and to allow a dehydrator to rotate smoothly when starting dewatering.

B) Means for Solving the Problems The present invention provides a dehydration tank 41&FC in which a motor for driving a dehydration tank is elastically supported at the bottom of the machine frame via a plurality of vibration isolation springs.
A shaft is inserted through the motor, the vibration isolation spring, and the bottom of the main body, and one end is fixed to the motor or the bottom of the machine frame. a stopper that comes into contact with the motor or the bottom of the machine frame to restrict further upward movement; a buffer provided between the stopper and the contact surface; and an elastic body that forms part of the shaft. It is equipped with the following.

Further, in the dehydrator of the present invention, a cylindrical body is provided at the outer bottom of the motor, and the center part of a substantially U-shaped regulating body is inserted into the cylindrical body to rotatably support the regulating body, and Both ends of the regulating body are pivotally supported on the bottom of the machine frame.

(E) Function: In the dewatering machine of claim 1, the shaft and the stopper restrict the expansion of the vibration isolation spring beyond a predetermined level due to the upward movement of the motor, so that the dehydrating tank is extremely Regulate the tilt.

In addition, the elastic body buffers pressure and twisting force in the direction of expansion and contraction that are applied to the support shaft.

Moreover, in the dehydrator of claim 2, since the regulating body is inserted through the cylindrical body, the extreme inclination of the motor (dehydration tank) is regulated by the regulating body, and the regulating body is not limited to the motor or the machine. Since it is rotatably supported on the bottom of the frame, there is no problem with the normal expansion and contraction movement of the vibration isolation spring.

(f) Example Embodiments of the present invention will be described based on the drawings.

However, the parts other than those described are the same as those in the conventional example, and therefore the description will be omitted.

FIG. 1 shows the anti-vibration bag/place [1] in the dehydrator of this embodiment, and the buffer cylinder (2) is made of an elastic rubber material.

(2) is a shaft inserted into the vibration isolating spring (goods), and the ends of the two metal shafts (2a) and (2b) are insert-molded through elastic rubber (3). It consists of: The upper end (2C) of the shaft (2) passes through the upper spring receiver (4) and the mounting piece (G) of the motor flash, is threaded, and is fitted with a nut (51 and washer (6)). The lower end (2d) of the shaft (2) completely penetrates the lower spring receiver (7) and the bottom of the machine frame (51a). The machine frame bottom (518) is threaded and slides in the vertical direction when the anti-vibration spring (B) expands and contracts with the vertical movement of the motor. A ring-shaped cushioning rubber (8) is fitted from below into the protruding part, and a nut (9) is inserted from below.
) are screwed together.

Further, the mounting pieces protrude in all directions from the motor field at 90 degree intervals, and each of the mounting pieces is provided with the above-mentioned locking device +1).

Due to the unbalanced load in the dehydration tank (G), the dehydration tank swings greatly from side to side when dehydration is started, causing the motor group to tilt. The nut (9) comes into contact with the back surface of the bottom of the machine frame (51) via the buffer rubber (8), and prevents further expansion of the vibration isolation spring (B).
] & regulates. At this time, according to the buffer rubber (8),
It softens the impact upon contact, and absorbs the pressure and twisting force in the expansion/contraction direction applied to the shaft (2) by the elastic rubber (3).

Note that the regulation by the nut (9) can be adjusted by the degree of screwing of the nut (9), and the lower end (2d) of the shaft (2) is fixed, and the upper end @ (2c) is fixed. Even if the groove is formed so as to be slidable, the same operation and effect will be achieved.

Next, FIGS. 2 to 4 show a vibration isolating device for a dehydrator according to another embodiment.

aυ is a holding body provided near the outer periphery of the outer bottom surface (55a) of the motor flash, and a hollow cylindrical body σ2 of the shape 1 is provided at the lower end.
The upper end of the cylindrical body σ2 is fixed so as to be orthogonal to the radial direction of the outer bottom surface (55a).

13m) is inserted into the cylindrical body α2 and rotatably supported. Nine, both ends (15b) of the regulating body 0 (
13c) are bent outward at 90 degrees and are elastically engaged in recesses (14a) (14b) formed in the lower spring receivers (7a) (7b) located opposite each other. ), even at these ends (15b) (15c)K,
Rotatably supported. The machine frame bottom (51a) is made of resin, and the lower spring receiver (71...
is screwed onto the support stand +lS, which is integrally formed to bulge out from the bottom (51a).

(9) The holding body aυ (cylindrical body 03) and the regulating body a3 are also provided at the 90 degree rotational position on the outer bottom surface (55a) of the motor (2).

Therefore, due to an unbalanced load in the dehydration tank (to), when the dehydration tank is started, the dehydration tank swings greatly from side to side, for example, even if the motor tilts in the direction of the arrow in FIG. Since the regulating body α3 is inserted into the cylindrical body α2, the opening edge of the cylindrical body t1z comes into contact with the regulating body a3. At this time, since the regulating body [31 itself has spring properties, the regulating body [13
is twisted, and its return force regulates the inclination of the motor.

Further, the regulating body faces the cylindrical body a3 and the bottom of the machine frame (
51a), so that during the normal expansion and contraction operation of the anti-vibration springs, they rotate appropriately as shown in Fig. 4 without interfering with the normal expansion and contraction operation.

It goes without saying that the dehydrator described in the above embodiments can be applied to a dehydrator included in a two-tub washing machine.

(G) Effects of the Invention In the dewatering machine of the present invention, the shaft body and regulating body regulate the inclination of the dehydration tank and motor when starting dehydration due to an unbalanced load, so that the dehydration tank collides with the outer dehydration tank. The dehydration start-up can be carried out smoothly without any accidents.

In addition, in the dehydrator according to claim 1, the elastic body absorbs the pressure (tensile force, torsional force, etc.) applied to the shaft body, and the shock absorber softens the impact at the time of contact, so that it is durable. Improves sex.
