Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a vibration isolating device for washing machines used in general households.

BACKGROUND ART A conventional vibration isolating device for a washing machine will be explained with reference to FIGS. 7 and 8. In the figure, reference numeral 1 denotes a main body, in which a washing tank 2 is suspended and supported in a vibration-proof manner by a support rod 3 via a suspension 4. Reference numeral 5 denotes a support fixed to the lower part of the side wall of the washing tub 2, and the washing tub 2 is elastically supported by the support 5 at the upper part of the suspension 4. Reference numeral 6 denotes a water tank in which clothes are washed and rotated at high speed for dehydration. At this time, it is rare for the clothes to be evenly distributed inside the water tank 6, and the dehydration process is performed with the clothes being unevenly distributed. to occur.

In order to reduce this vibration, it is generally necessary to increase the weight of the vibration system such as the washing tub 2 supported by the support rod 3.

As a method of increasing the weight of the conventional vibration system, as shown in FIG. 7, a concrete weight 9 is fastened to the bottom of the washing tub 2 with bolts 10 in a direction substantially opposite to the electric motor 7 through a reinforcing plate 8. It was hot.

Problems to be Solved by the Invention This conventional configuration has the following problems.

(1) Generally, the thickness of the reinforcing plate 8 is about 1 to 2 mm, and the bolt through hole of the weight 9 is considerably larger than the diameter of the bolt 10 due to its manufacturing. Therefore, the bolt 10 connects the weight 9 to the reinforcing plate 8.
When fastening, the reinforcing plate 8 may be deformed by the fastening force, and the corners of the weight 9 may crack, and many man-hours are required to manage the fastening force during assembly.

(2) Before tightening the bolts 10, the weight 9 and the reinforcing plate 8 must be positioned. At that time, the weight 9 and the reinforcing plate 8 are generally shifted from each other. In some cases, parts were chipped or the reinforcing plate 8 was scratched.

(3) If the bolt 10 loosens during operation, the weight 9 may be displaced due to the vibration force of the vibration system and detached from the reinforcing plate 8, resulting in an extremely dangerous situation.

In view of the above-mentioned problems, the present invention aims to provide a vibration isolating device for a washing machine in which the corners of the weight are not chipped, the assembly is simplified, and the key does not come off from the reinforcing plate. do.

Means for Solving the Problems In order to solve the above problems, the washing machine vibration isolator of the present invention has a seat plate with a positioning part interposed between the weight and the reinforcing plate, and they are connected by bolts 10. It is fastened.

Effect With the above configuration, by interposing the seat plate provided with the positioning part, deformation of the reinforcing plate can be prevented even when a large fastening force is applied to the bolt, and chipping and cracking of the corners of the weight can be prevented. It is possible to eliminate it.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 5. In the figure, reference numeral 8 denotes a reinforcing plate, which is fastened to the bottom of the washing tub 2.
A mechanism section 12 including an electric motor 7 and a clutch mechanism.
has been concluded. 9 is a concrete weight,
It is attached by bolts 10 in a direction substantially opposite to the electric motor 7 in plan view.

Reference numeral 11 designates a seat plate held between the reinforcing plate 8 and the weight 9, and has upwardly bent portions 11a near both ends of the seat plate, so that when the weight 9 is attached, the base of the seat plate is It is located at a distance of 0.3 to 1.5 mm from the side surface. Further, this bent portion has a slope with an angle x of 5 to 10 degrees so that it opens upward as shown in FIG. Furthermore, a bent portion 11b for positioning with the reinforcing plate 8 is provided below, and a fitting hole 8a for the downwardly bent portion 11b is provided at a corresponding position on the reinforcing plate 8. This downward bent portion 11b and the fitting hole 8
As shown in FIG. 4, the relationship with point a is C-shaped, and the fitting relationship with the partner can be regulated only by the position and angle of point A, improving positional accuracy.

As described above, according to this embodiment, it is possible to store the weight in a predetermined position using the upper bent portion of the seat plate as a guide, so it is possible to significantly reduce the number of man-hours in terms of assembly or assembly management. This will improve the quality of the weight. Furthermore, since the bent portion supports the side surface of the weight, even if the bolt becomes loose, the weight will not be displaced and no dangerous situation will occur.

Effects of the invention As described above, according to the invention, the reinforcing plate is not deformed due to fastening of bolts, so there is no possibility that the corners of the weight will be chipped during assembly. Furthermore, since the seat plate is provided with an upwardly bent portion to position the weight, ease of assembly can be improved.
