Abstract
A drum washing machine prevents the weight of a balance weight from concentrating on a screw welding part of an outer drum. The drum washing machine comprises: a case (10); an outer cylinder (20) in which a drum (22) for accommodating laundry is rotatably installed; an outer cylinder support table (30) connected to the case (10) through a plurality of dampers (28) and swingably supporting the outer cylinder (20); an outer tub band (31, 32) fixed to the outer tub support base (30) by welding, extending along the outer peripheral surface of the outer tub (20); and a balance weight (D) connected to one end (31a, 32a) and the other end (31b, 32b) of the outer tub band (31, 32) at the upper part of the outer tub (20).
Description
The present invention relates to a drum washing machine that performs, for example, a washing process, a rinsing process, and a dehydrating process.
The drum washing machine washes laundry by: a drum of a cylindrical shape is rotatably disposed inside an outer drum disposed in a cabinet about a horizontal axis or an inclined axis, and the drum is rotated in a state where laundry is contained in the drum and water is stored in the outer drum.
In a drum washing machine, an outer drum in which a drum is built is supported by a damper and a spring in order to reduce transmission of vibration to a cabinet when the drum is rotated at a high speed.
Therefore, although the outer tub is freely swung inside the cabinet by an elastic member such as a damper or a spring, the weight of the outer tub itself needs to be increased in order to suppress large vibration when the drum is rotationally driven at a high speed particularly during the dehydration.
Therefore, in the drum washing machine, a balance weight of a predetermined weight is mounted on an upper portion of the outer tub. Therefore, the weight of the outer tub itself becomes heavy, and vibration caused by unbalance of the laundry during the dehydration can be reduced.
In the conventional drum washing machine 101, as shown in fig. 7, balance weights 150 and 160 are mounted on the upper part of the outer tub 120. The outer cylinder 120 is supported to be freely swingable, for example, by a plurality of springs/dampers 128.
As shown in fig. 8, reinforcing plates 151 and 161 are welded to the outer cylinder 120, and a plurality of screws 152a and 162a for fixing the balance weights 150 and 160 are welded to the reinforcing plates 151 and 161. The reinforcing plates 151 and 161 are plate-shaped members having a thickness greater than that of the outer cylinder 120.
In a state where the plurality of screws 152a, 162a are inserted into the plurality of through holes 150a, 160a formed in the counterweights 150, 160, respectively, nuts 152b, 162b are screwed to the screws 152a, 162a, and the counterweights 150, 160 are fixed to the reinforcing plates 151, 161.
As described above, the screws 152a and 162a for fixing the balance weights 150 and 160 are directly welded to the reinforcing plates 151 and 161 fixed to the outer tube 120 without being welded to the outer tube 120, in order to prevent the weight of the balance weights 150 and 160 from being concentrated on the screw welding portion of the outer tube 120 having a small thickness.
However, in the drum washing machine 101, there is a risk that the weight of the balance weights 150 and 160 concentrates on the screw welding portions of the reinforcing plates 151 and 161, and the weld is cracked.
Further, since the reinforcing plates 151 and 161 having a thickness greater than that of the outer cylinder 120 are used in order to prevent the weight of the balance weights 150 and 160 from concentrating on the screw welding portion of the outer cylinder 120 having a small thickness, the number of parts increases.

The screw 85a has a length that allows the through hole 55a of the connecting portion 55 and the through hole 65a of the connecting portion 65 to be inserted therethrough in a state where the connecting portion 55 of the first balance weight 50 and the connecting portion 65 of the second balance weight 60 are separated from each other.
Similarly, the connection portion 56 of the first balance weight 50 and the connection portion 66 of the second balance weight 60 are connected by inserting the screw 86a into the through hole 56a of the connection portion 56 and the through hole 66a of the connection portion 66 and screwing the nut 86b to the screw 86 a. Thus, the screw 86a and the nut 86b are the connecting member 86 of the present invention.
The screw 86a has a length that allows the through hole 56a of the connecting portion 56 and the through hole 66a of the connecting portion 66 to be inserted therethrough in a state where the connecting portion 56 of the first balance weight 50 and the connecting portion 66 of the second balance weight 60 are separated.
Therefore, the connection portion 55 of the first balance weight 50 connected to the one end portion 31a of the outer tub belt 31 and the connection portion 65 of the second balance weight 6 connected to the other end portion of the outer tub belt 31 are connected by the connection member 85. Further, the connection portion 56 of the first balance weight 50 connected to the one end portion 32a of the outer tub belt 32 and the connection portion 66 of the second balance weight 60 connected to the other end portion of the outer tub belt 32 are connected by a connection member 86.
As described above, the tub belt 31, 32 and the first and second balance weights 50, 60 are connected by the connecting members 85, 86 in a state of being disposed over almost the entire circumference of the outer tube 20, whereby the tub belt 31, 32 fixes the outer tube 20 to the outer tube support base 30 and fixes the first and second balance weights 50, 60 to the upper portion of the outer tube 20.
Next, a method of fixing the first balance weight 50 and the second balance weight 60 to the upper portion of the outer tube 20 will be described with reference to fig. 6.
In the following description, the connection between the tub belt 31 and the first and second balance weights 50 and 60 and the connection between the connection portion 55 of the first balance weight 50 and the connection portion 65 of the second balance weight 60 are described, but the connection between the tub belt 32 and the first and second balance weights 50 and 60 and the connection between the connection portion 56 of the first balance weight 50 and the connection portion 66 of the second balance weight 60 are the same, and therefore, the description thereof is omitted.
First, as shown in fig. 6 (a), in a state where the outer tub band 31 is fixed to the outer tub support base 30 by welding, as shown in fig. 6 (b), the outer tub 20 is disposed on the outer tub band 31.
Thereafter, as shown in fig. 6 (c), the first balance weight 50 and the second balance weight 60 are disposed on the upper portion of the outer tube 20. At this time, the one end 31a of the outer tub band 31 and the other end 31b of the outer tub band 31 are fixed by the screw 81a, the nut 81b, the screw 82a, and the nut 82b in a state of being inserted into the opening 52 and the opening 62 of the first balance weight 50 from below.
The screw 85a is inserted through the through hole 55a of the connecting portion 55 of the first counterweight 50 and the through hole 65a of the connecting portion 65 of the second counterweight 60, and a nut 85b is fitted near the tip of the screw 85 a. Therefore, the first balance weight 50 and the second balance weight 60 are in a temporarily fixed state.
Thereafter, as shown in fig. 6 (d), the nut 85b is screwed to the screw 85a inserted through the connecting portion 55 of the first balance weight 50 and the connecting portion 65 of the second balance weight 60.
Therefore, by screwing the nut 85b to the screw 85a, the gap between the connecting portion 55 of the first balance weight 50 and the connecting portion 65 of the second balance weight 60 is reduced.
At this time, the outer tub band 31, the first balance weight 50, and the second balance weight 60 tighten the outer peripheral surface of the outer tub 20, and the outer tub 20 is supported by friction between the outer tub band 31, the first balance weight 50, and the second balance weight 60. Accordingly, the outer tube 20 is fixed to the outer tube support stand 30 by the outer tube band 31, and the first balance weight 50 and the second balance weight 60 are fixed to the upper portion of the outer tube 20.
In addition, the torque of screwing the nut 85b to the screw 85a when the connecting portion 55 of the first balance weight 50 and the connecting portion 65 of the second balance weight 60 are connected is made the same as the torque of screwing the nut 86b to the screw 86a when the connecting portion 56 of the first balance weight 50 and the connecting portion 66 of the second balance weight 60 are connected, whereby the outer cylinder 20, the first balance weight 50, and the second balance weight 60 can be fixed equally.

Accordingly, in the drum washing machine 1 according to the present embodiment, since no welding screw is used for fixing the balance weight D, there is no risk of the weld being broken. Further, the outer tube 20 is fixed to the outer tube support base 30 and the balance weight D is fixed to the upper portion of the outer tube 20 by the outer tube band 31, 32, so the number of parts can be reduced.
In the drum washing machine 1 of the present embodiment, the balance weight D includes: a first balance weight 50 connected to one end portions 31a, 32a of the outer tub belt 31, 32 as a fitting member; a second balance weight connected to the other ends of the outer tub belt 31, 32 as the fitting member; and connecting members 85, 86 connecting the first balance weight 50 and the second balance weight 60.
