In this case, if the thickness t1 of the first surface is the same as the thickness t2 of the third surface, the first surface 811 and the second surface 812 form the through hole 82 of the connector body. It is likely to bend toward.

As mentioned above, when the connector body 81 is made of a plastic body such as plastic, the connector body 81 can be produced through injection molding in which a plastic resin is injected into a mold and then hardened. have. When manufacturing the connector body 81 through injection molding, although the lengths of the first and second surfaces are set longer than the lengths of the third or fourth surfaces, the thickness t1 of the first surface is adjusted. If the thickness of the three sides (t2) is the same, the speed of hardening of the third and fourth surfaces 813 and 814 and the hardening speed of the first and second surfaces 811 and 812 are different. There is a high possibility that the 811 and the second surface 812 bend toward the through hole 82.

When the first and second surfaces 811 and 812 are bent toward the through-hole 82, a space is formed between the discharge pipe 53 and the connector body 81, so that the inside of the discharge pipe 53 There is a risk that moving water will leak into the cabinet 1. In order to prevent such a problem, the thickness t1 of the first surface is preferably set to be thicker than the thickness t2 of the third surface.

That is, as shown in FIG. 6(b), a cross section in the thickness direction of the first surface 811 is provided in a convex shape toward a direction away from the center of the through hole 82, and the second surface 812 ) May be provided in a convex shape toward a direction away from the center of the through hole 82.

If the first surface 811 and the second surface 812 are provided in the shape as shown in FIG. 6(b), the first surface 811 and the second surface 812 are deformed during the injection molding process (FIG. 6 Even if the dotted line in (b) occurs, the possibility of leakage of water into the space between the discharge pipe 53 and the first surface 811 and the space between the discharge pipe 53 and the second surface 812 can be minimized. I can.

Unlike shown in FIG. 6(b), the lengths of the first and second surfaces 811 and 812 are set equal to each other, and the lengths of the third and fourth surfaces 813 and 814 Is the same as each other, but when it is set longer than the length of the first surface 811, the above-described effect can be expected only when the thickness t2 of the third surface is set to be thicker than the thickness t1 of the first surface. . In this case, a cross section in the thickness direction of the third surface 813 is provided in a convex shape toward a direction away from the center of the through hole 82, and a cross section in the thickness direction of the fourth surface 814 is the through hole ( 82) may be provided in a convex shape toward a direction away from the center.

With the above-described connector 8, the present invention can provide a laundry treatment apparatus capable of effectively preventing leakage as well as easy assembly of the discharge pipe 53 and the inlet pipe 42.

7 shows an example of the discharge pipe 53, the discharge pipe 53 of FIG. 7 is a storage connection pipe 535 fixed to the case 51, the inflow of the insulation through the connector 8 It may be provided as an insulating part connecting pipe 537 connected to the pipe 42, and a trap forming pipe 536 forming a water trap between the storage part connecting pipe and the insulating part connecting pipe.

The trap forming tube 536 may be provided to form any one of a P-trap, a U-trap, and an S-trap, and the trap The clothing treatment apparatus 100 of the present invention may block communication between the inner space of the tub body 21 and the inner space of the case 51 through the forming tube 536. Through this, the present invention may block the movement of the foam inside the tub body to the case 51 through the discharge pipe 53. Further, when the laundry treatment apparatus of the present invention is used as a dryer, the trap forming pipe 536 has a means for preventing the heated air supplied to the tub body from leaking to the outside of the tub body through the discharge pipe 53 Will be

Water stored in the trap forming pipe 536 may be discharged to the insulating body 41 according to a pressure change in the tub body 21 that occurs when the user opens the door 135. This is because when the door 135 opens the inlet 131, the pressure inside the tub body 21 is temporarily lowered, and thus the water in the trap forming pipe 536 can move to the inlet pipe 42. .

Since the water stored in the trap forming pipe 536 is water remaining in the discharge pipe 53 after the completion of the water supply process or the detergent supply process, or a mixture of water and detergent, it does not cause a problem related to hygiene, but It may cause misunderstandings, such as damage to the detergent supply, to users who use the product.

In order to minimize such a problem, the discharge pipe 53 is further provided with a reduction unit for reducing the flow rate of water moving from the trap forming pipe 536 to the insulating part connection pipe 537.

When the speed of water moving from the trap forming pipe 536 to the inlet pipe 42 by the reduction part decreases, the water flows along the surface of the insulating part 4 to the connection body 415 provided in the insulating body. Will move. When water moves along the surface of the insulating part 4 to the connection body 415, the user will not be able to recognize that water is discharged from the trap forming pipe 536, so the user's misunderstanding such as damage to the detergent supply unit Can be prevented.

When the trap forming pipe 536 projected on the bottom surface of the cabinet 1 and the insulating part connector 537 projected on the bottom surface of the cabinet are provided to form an angle of 90 degrees or more and 120 degrees or less, An inflection point (channel inflection point) will be formed in a flow path connecting the trap forming pipe 536 and the inflow pipe 42, and the flow path inflection point moves from the trap forming pipe 536 toward the inflow pipe 42. There is an effect of lowering the flow rate of water.

The effect of lowering the flow rate is greatest when the trap forming pipe 536 and the insulating part connecting pipe 537 are provided so as to be orthogonal. In this case, the insulating part connecting pipe 537 is the width direction of the front panel 13 of the cabinet. It is provided parallel to (X-axis direction), and the trap forming pipe 536 will be provided in parallel to the width direction (Z-axis direction) of the first side panel 16 of the cabinet.
