Description

[Detailed Description of the Invention] The present invention relates to a washing machine that can perform rinsing on the spin-drying tank side.

Conventionally, in this type of washing machine, the rinsing water supplied from the tap etc. is supplied to the dehydration tank side through a water supply channel installed below the control box, but if the water faucet is opened too much, for example. When more than a specified amount of water is supplied to the water supply channel, water overflows from the water supply channel, and the water leaks from between the lid frame attached to the upper opening of the dehydration tank and the bottom surface of the operation box. This causes problems in that it is unsightly and the user is likely to be under the impression that a malfunction has occurred.

Therefore, the purpose of the present invention is to erect a weir plate part in the part of the lid frame attached to the dewatering tank that covers the upper part of the water supply channel, and to use the weir plate part to prevent the excess water flowing through the water supply channel. To provide a washing machine which prevents water from flowing onto a lid frame even when excessive water is supplied to a water supply channel by stopping water from flowing into a washing tub.

An embodiment of the present invention will be described below with reference to the drawings. 1 is an outer box; 2 is a tub body made of plastic, for example, which has a washing tub 3 and a dehydration tub 4 housed inside the outer box 1;
A drainage chamber 5 extending from the bottom of the tank to the top is formed by vertically bulging the peripheral wall at the rear part of the tank. The washing tub 3 and the drain chamber 5 are separated by a strainer plate 6 so that water can pass therethrough, and a drain port (both not shown) connected to a drain hose is formed at the inner bottom of the drain chamber 5. There is. Reference numeral 7 denotes a dehydration basket rotatably disposed within the dehydration tank 4, which is rotatably driven by a dehydration motor 8. Reference numeral 9 denotes an operation box erected at the rear of the upper surface of the outer box 1, and a water supply cylinder 10 is erected thereon, which is connected to a water source such as a water faucet via a water supply hose (not shown). Reference numeral 11 denotes a water supply case provided along the outer bottom of the operation box 9, and a partition wall 11a is formed at a portion located approximately in the center of the case and approximately directly below the water supply tube 10 to divide the water supply case 11 into left and right parts. A washing tank water inlet 11b is formed in the lower part of the front wall on the left side of the partition wall 11a, and the right side is used as a water supply channel 12 to the dewatering tank 4 side. The water supply channel 12 is curved toward the dehydration tank 4 above the drain chamber 5 of the washing tub 3, and a portion near the end is recessed on the upper surface of the tank body 2 so as to be located between the drain chamber 5 and the dehydration tank 4. It is fitted into the groove 13, and a water inlet 14 for the dehydration tank is formed at the end. Although not shown, a water supply switch is provided above the partition wall 11a of the water supply case 11 so as to be movable from side to side, with both upper and lower ends open. By operating the switching lever 15 left and right, water flowing down from the water supply cylinder 10 is transferred to the washing tub 3 side and the dehydration tub 4 via the water supply case 11.
It is possible to selectively supply it to the side. Reference numeral 16 denotes a lid frame that is attached to the open upper end of the dehydration tank 4, and a mounting plate portion 18 is integrally formed at the rear end of the lid frame via a self-hinge portion 17. 18
A pair of engaging recesses 19 are formed at the rear edge of the holder.
The mounting plate portion 18 of the lid frame 16 has an engaging recess 19.
is press-fitted into a pair of pillars 20 which are integrally erected on the upper surface of the tank body 2 and located behind the dehydration tank 4, and is also sandwiched between the upper surface of the tank body 2 and the lower end of the front wall of the operation box 9. The lid frame 16 normally has an engaging protrusion 16a protruding from its front end and a recess (not shown) formed inside the front end of the dehydration tank 4.
It is removably attached to. Since the lid frame 16 can be opened and closed by bending at the self-hinge portion 17, even if laundry should jump out of the dehydration basket 7 and fall into the dehydration tank 4 during centrifugal dehydration, for example, it can be taken out. be able to.
The mounting plate portion 18 of the lid frame 16 fixed in this manner is positioned so as to cover the upper part of the terminal end of the water supply channel 12 that exists on the rear upper surface of the dehydration tank 4, but there is no escape on both side walls of the terminal region of the water supply channel 12. The portion 21 is formed with a cutout,
The mounting plate portion 18 is fitted into this relief portion 21. Then, a discharge part 22 is formed in the left side wall of the water supply channel 12 so as to be continuous with the relief part 21 and located above the drainage chamber 5, and as will be described later, the water supply channel 12 is cut out.
2 is made to overflow from the discharge part 22. 23 is a laundry inlet/outlet formed approximately in the center of the lid frame 16, and 24 is a water injector attached to the laundry inlet/outlet 23 so as to be openable and closable. The water is poured into the dewatering basket 7 via the water injector 24. 25 is the weir plate part, this is the lid frame 1
6, the portion that covers the upper part of the water supply channel 12, that is, the rear left end portion of the mounting plate portion 18, is aligned with the notch portion 21 on the right side of the mounting plate portion 18 so as to be substantially perpendicular to the water supply channel 12. Engagement recess 1
It is formed by continuous integral molding from the inner peripheral edge of 9 to the right side.

Next, the effect of the above configuration will be explained for the case of performing dehydration rinsing, which is directly related to the present invention.
The laundry that has been washed with detergent in the washing tub 3 is stored in the dehydration basket 7, and the water supply switch is switched to the dehydration tub 4 side. After that, when the dewatering basket 7 is rotated and the water faucet is opened to supply tap water, the tap water flows down to the water supply case 11 via the water supply switch, flows through the water supply case 11, and enters the water injector 24. Dehydration basket 7
The water supplied into the dehydration basket 7 permeates the laundry and is dehydrated by centrifugal force, resulting in so-called dehydration rinsing. By the way, when performing dehydration rinsing, for example, if the water faucet is opened too much, a large amount of water is supplied into the water supply case 11 and the running water level rises, and the excess water is poured into the dehydration tank of the water supply channel 12 in the lid frame 16. There is a risk that the water may run onto the portion that covers the upper part of the water inlet 14 and flow onto the lid frame 16. However, in this case, excess water hits the weir plate part 25 and is dammed, so it overflows from the discharge part 22 of the water supply channel 12 and flows into the drain chamber 5 on the side of the washing tub 4, causing the lid frame 16 can be prevented from flowing out. Moreover, in this embodiment, the weir plate part 25 is installed upright in the part of the cover frame 16 that covers the upper part of the water supply channel 12. Therefore, for example, the weir plate part 25 is installed on the outer bottom of the operation box 9 above the water supply channel 12. A slight gap is not unavoidably created between the lower end of the weir plate and the lid frame, unlike the case where the weir plate is formed in a hanging state. This makes it possible to more reliably prevent water from flowing onto the lid frame 16.

In particular, in this embodiment, the engaging recess 1 of the lid frame 16
9 is fitted into the support column 20, the deformation of the common wall 2a of the washing tub 3 and the dehydration tub 4 during molding can be corrected, and the washing tub 3 in the form of being separated by the drain chamber 5 can be corrected. The peripheral wall portion (common wall 2a) can be reinforced, and the entire tank body 2 can be reinforced.

As described above, the present invention has a weir plate part erected in the part of the lid frame attached to the dehydration tank that covers the upper part of the water supply channel, and the weir plate part absorbs excess water flowing through the water supply channel. Provided is a washing machine that is characterized by being dammed and drained into the washing tub, thereby preventing water from flowing onto the lid frame even when excessive water is supplied to the water supply channel. can.
