Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a dewatering tub of a washing machine for accommodating an item to be washed and used for washing.

[0002]

[Prior Art]

 In recent years, as the capacity of washing machines has increased, there has been a strong demand for improvements in washing / dewatering performance in small capacities.

Conventionally, a dehydrating tub of this type of washing machine has a configuration as shown in FIGS. 5 and 6. The configuration will be described below with reference to the drawings. As shown in the figure, the inner tub 2 rotatably provided in the outer tub 1 is provided with a rotary blade 3 at the bottom thereof, and the rotational force of the motor 4 passes through the V belt 5 and the mechanical case 6 during washing. Transmitted to the rotor 3. A water channel 7 communicates from the bottom of the inner tank 2 to the upper part of the peripheral wall. The water channel 7 is formed by the inner wall of the inner tank 2 and a mounting plate 8 having a substantially U-shaped cross section, and the mounting plate 8 is the inner tank. It is attached to a locking portion 9 formed as an outer wall of the water channel 7 on a part of the peripheral wall of 2. A plurality of opening holes 10 are formed in the peripheral wall of the inner tank 2. Then, due to the rotation of the back blade 3a formed on the rotary blade 3, the water in the inner tank 2 circulates in the water channel 7, and the thread waste of the circulating water is collected in the filter 11 mounted on the upper portion of the inner tank 2. ing.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned conventional configuration, when a small amount of clothes is accommodated in the large-capacity inner tub 2 for washing and dehydration, the clothes are displaced by centrifugal force when dehydrating and are located near the mounting plate 8. In this case, water is often dehydrated. In this case, since the mounting plate 8 has no opening hole, the water content of the clothes generated by the rotation of the inner tub 2 cannot escape to the water channel 7, There was a problem that the clothes were not squeezed sufficiently after the completion of dehydration.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a dewatering tub for a washing machine that can obtain stable dewatering performance regardless of the position of clothes in the inner tub.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention takes an inner tank which is rotatably arranged in an outer tank and has a water channel communicating with a rotary vane, and a waste thread of circulating water which is arranged above the water channel. A filter and a mounting plate attached to the locking portion of the water channel are provided, and a first concave groove is formed in the mounting plate from the bottom to the upper side, and the bottom of the first concave groove has an upper opening. A louver-shaped first opening hole is formed, a second concave groove communicating with the outer tank is formed in the locking portion from the bottom to the upper side, and the first groove at the position above the filter is formed. A second opening is formed in the concave groove 2.

[0007]

[Action]

 In the above-mentioned structure, when the clothes are dehydrated by being located near the attachment plate during the dehydration, the water content of the clothes enters the waterway through the first concave groove and the second opening hole, and the water that enters the waterway. Since it passes through the second concave groove and the second opening hole to the outer tank, the dehydration performance can be maintained.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. In this embodiment, the same components as those shown in the above-mentioned conventional example are designated by the same reference numerals, and the description thereof will be omitted. The characteristic structure of this embodiment is that a recessed groove is formed in the engaging portion and the mounting plate of the inner tank described in the conventional example, and a hole is provided in the recessed groove portion. That is, the mounting plate 13 attached to the locking portion 12 of the inner tank 2 is formed with the first concave groove 14a from the bottom to the upper side, and the both end surfaces facing the locking portion 12 are formed into a convex shape. The inner surface of the tank 2 and the convex surface are flush with each other. Further, a plurality of louver-shaped first opening holes 15a having an upper opening are formed on the bottom surface of the first concave groove 14a. Further, the engaging portion 12 of the inner tank 2 is formed with a second concave groove 14b communicating with the outer tank 1 from the bottom to the upper side, and the second concave groove 14b at a position higher than the filter 11 is provided with the second concave groove 14b. A plurality of opening holes 15b are formed.

Next, the operation will be described. At the time of washing, when the rotary blades 3 rotate, the pumping action of the back blades 3a causes the water at the bottom of the inner tub 2 to be sucked and circulated through the water passage 7 and the filter 11, and a part of the circulating water is It is discharged into the outer tank 7 through the concave groove 14b and the second opening hole 15b. On the other hand, at the time of dehydration, the water contained in the clothes is squeezed out by the rotation of the inner tank 2. At this time, when the clothes are located near the mounting plate 13, the mounting plate 13 has the first concave groove 14a and the first opening hole 15a, so that the dehydrated water is discharged into the water channel 7. Then, the water discharged into the water channel 7 flows out to the outer tub 1 through the second concave groove 14b and the second opening hole 15b.

As described above, according to the dewatering tub of the washing machine of the embodiment, even when the clothes are located near the mounting plate 13 during dewatering, the first concave groove 14 a formed in the mounting plate 13 and the first concave groove 14 a are formed. The water content of the clothes enters the water channel 7 through the opening hole 15a and the water content that enters the water channel 7 passes through the second concave groove 14b and the second opening hole 15b to the outer tub 1 to maintain the dehydration performance. it can. In a large-capacity washing machine inner tub 2, when a small amount of water is dehydrated, the clothes often shift to the vicinity of the mounting plate 13, but even in such a case, the dehydration performance does not vary. .. Further, since the second opening hole 15b is located above the filter 11 during washing, it is possible to minimize the amount of circulating water discharged from the second opening hole 15b. The performance of can be maintained. Furthermore, since the surface facing the locking portion 12 is made convex so that the inner surface of the inner tub 2 and the convex surface are flush with each other, even if clothes rotate during washing, they will not be caught and broken.

[0011]

[Effect of the device]

 As is clear from the above-mentioned embodiment, the dewatering tub of the washing machine of the present invention is arranged in the outer tub so as to be rotatable and has an inner tub having a water channel communicating with the rotor blades, and an upper tub of the water channel. A first recessed groove is formed on the mounting plate from the bottom to the upper side, and the first recessed groove is provided on the mounting plate. A louver-shaped first opening hole having an opening at the top is bored on the bottom surface, and a second recessed groove communicating with the outer tank is formed at the locking portion from the bottom to the upper side. A second opening is formed in the second concave groove at the upper position. With this configuration, the dehydration performance can be maintained even if the clothes are deviated during dehydration, Stable dehydration performance can be obtained.
