<Drainage device 100>
As shown in FIG. 4, the drainage device 100 includes a drain electromagnetic valve 110, a horizontal pipe 120, and a vertical pipe 130.
The drainage electromagnetic valve 110 includes an electromagnetic coil 111 and a valve portion 112 including a valve body (not shown) that is driven by excitation of the electromagnetic coil 111. A terminal portion 113 is provided on the upper surface of the electromagnetic coil 111, and electric power for exciting the electromagnetic coil 111 is supplied to the terminal portion 113 via a harness (not shown).
The electric power supplied to the electromagnetic coil 111 is supplied based on a command or the like of a control device (ECU) (not shown) according to the operation mode of the washing / drying machine 1 or the like. The electromagnetic coil 111 is covered with an insulating material or the like.

The valve portion 112 is disposed at the front end portion of the horizontal pipe 120. A vertical pipe 130 is connected to the lower portion of the front portion of the horizontal pipe 120, and the valve unit 112 switches communication / blocking (opening / closing) between the horizontal pipe 120 and the vertical pipe 130. A fitting protrusion (not shown) for fitting and fixing the valve portion 112 is provided on the peripheral wall of the front end portion of the horizontal pipe 120.
Here, the drain pipe k1 described above is connected to the rear end portion of the horizontal pipe 120, and waste water such as washing water discharged from the outer tub 5 flows through the horizontal pipe 120 through the drain pipe k1. It is like that.
Then, when the electromagnetic coil 111 of the drain electromagnetic valve 110 is excited by the control of the ECU (not shown) and the valve body (not shown) of the valve unit 112 is moved and opened in the direction in which the horizontal pipe 120 and the vertical pipe 130 communicate with each other, Drainage flows from the horizontal pipe 120 to the vertical pipe 130.
In addition, the electromagnetic coil 111 is demagnetized under the control of the ECU (not shown), and the valve body (not shown) of the valve unit 112 is returned in a direction that blocks the communication between the horizontal pipe 120 and the vertical pipe 130 (returned by an urging means or the like). When closed), the flow of drainage from the horizontal pipe 120 to the vertical pipe 130 is blocked.
That is, the discharge / non-discharge of the wastewater is controlled by switching the excitation / demagnetization of the electromagnetic coil 111.

  The horizontal pipe 120 is a stepped pipe in which the front part 121 has a large diameter and the rear part 122 has a small diameter, and is attached and fixed to a base part 2b (see FIG. 3; the same applies hereinafter) on the peripheral wall of the front part 121. A mounting portion 121a (see FIG. 3) is formed. Moreover, the vertical piping 130 is connected to the lower part of the front part so as to be orthogonal to each other, and a valve body (not shown) of the drain electromagnetic valve 110 is disposed so as to be positioned at a communication portion of the connecting part.

  Further, a branch port 123 is formed in the side portion (here, the right side portion) of the horizontal pipe 120, and the downstream end of the circulation pipe 124 is connected to the branch port 123. The upstream end of the circulation pipe 124 is connected to a circulation pump P1 (see FIG. 2). Accordingly, when the circulation pump P1 is operated in a state where the electromagnetic coil 111 of the drain electromagnetic valve 110 is demagnetized and a valve body (not shown) is closed (for example, operation during a washing process in which washing is performed by circulating washing water). ), The waste water flowing into the horizontal pipe 120 from the drain pipe 1k flows from the branch port 123 to the circulation pipe 124 and is supplied from the circulation pump P1 to the internal pipe k2 (see FIG. 2) serving as a circulation path. ing.

  The upper end of the vertical pipe 130 is connected to the lower part of the front part 121 of the horizontal pipe 120, and when the drain electromagnetic valve 110 is opened as described above, drainage flows from the horizontal pipe 120. The lower part of the vertical pipe 130 is bent and extended rearward, and the drainage hose 17 is connected to the connection port 102 at the rear part. That is, the drainage hose 17 is disposed with a predetermined height difference between the drainage hose 17 and the drainage hose 17 smoothly flows drainage flowing through the vertical pipe 130.

As shown in FIG. 3, the drainage hose 17 is held in a drainage hose guide 40 having a substantially U shape in plan view provided at the bottom of the base portion 2b, and a drainage hose removal provided on the side wall 2b1 of the base portion 2b. It is led to the drainage hose outlet 200 provided in the outlet 200 or the right side wall 2b2 and led out to the outside.
The drainage hose 17 is flexible so as to be deformable in the radial direction, and is deformed into a flat shape when the user presses the fingertip in the radial direction as will be described later.

  Since the drain hose outlet 200 has the same structure on the left and right side walls 2b1, 2b2 of the base portion 2b, the drain hose outlet 200 provided on the left side wall 2b1 will be described here. In addition, although the drain hose outlet 200 showed the example comprised by incorporating the extraction part member 200 '(refer FIG.5 (b)) made into the separate body in the side wall 2b1 (2b2), it is restricted to this. The drain hose outlet 200 may be integrally provided on the side walls 2b1 and 2b2.

  In the drainage hose outlet 200, as shown in FIG. 5A, the upper wall 41 of the drainage hose guide 40 is curved upward and bulged. As shown in FIG. 6 (a), the drain hose 17 is, at the drain hose outlet 200, a first extraction position where the drain hose 17 is linearly extracted at substantially the same height as the upstream side of the drain hose guide 40, and FIG. As shown in b), at the drain hose outlet 200, the second outlet is taken out sideways along the upper wall 41 of the drain hose guide 40 while being inclined upward from the first outlet position. The position can be taken. Here, the second extraction position is set such that the drainage hose 17 is disposed at a position higher than the upper surface 17a of the drainage hose 17 disposed at the first extraction position. In other words, the drain hose 17 arranged at the first take-out position and the drain hose 17 arranged at the second take-out position do not interfere with the arrangement position of the drain hoses 17 in the vertical direction. They are arranged at a predetermined interval. As a result, when the drain hose 17 is disposed at the second extraction position, a drain trap is formed between the drain hose 100 and the drain device 100 as will be described later.

As shown in FIG. 5B, the side wall 2b1 is provided with an insertion hole 201 having a round cross section slightly larger than the outer diameter φ1 of the drainage hose 17 so as to correspond to the first extraction position. A similar insertion hole 202 is provided so as to correspond to the second extraction position.
The two insertion holes 201 and 202 are arranged side by side in the vertical direction, and a communication portion 203 that connects these two insertion holes 201 and 202 is formed. The inner surface of the communication portion 203 has a rounded shape, and a drainage hose 17 ′ deformed into a flat shape can be inserted between them as shown in FIG. 5 (c). That is, the drainage hose 17 can move between the upper and lower two insertion holes 201 and 202 through the communication portion 203 in a state where the drainage hose 17 is deformed into a flat shape (state of the drainage hose 17 ′).

  Therefore, the drainage hose 17 can be moved to the second removal position by deforming the drainage hose 17 in a flat shape from the state where the drainage hose 17 is disposed at the first removal position. The drainage hose 17 can be moved to the first removal position by deforming the drainage hose 17 in a flat shape from the state where the drainage hose 17 is arranged at the removal position.

Here, at the first take-out position, as shown in FIG. 7, the drainage hose 17 is arranged with a predetermined height difference H1 between the upstream drainage device 100 and the drainage hose.
On the other hand, as described above, the second extraction position is set so that the drainage hose 17 is disposed at a position higher than the upper surface 17a of the drainage hose 17 disposed at the first extraction position. When the drainage hose 17 is positioned at the take-out position 2, a drainage trap using the height difference H <b> 1 of the drainage hose 17 is formed between the drainage device 100 and the insertion hole 202. Accordingly, a part of the drainage is stored in this portion, and even when odor is raised from the downstream side of the drainage hose 17, it can be suitably blocked by the drainage trap.

Since the washing / drying machine 1 of this embodiment can set the drainage hose 17 to the 1st taking-out position and the 2nd taking-out position in the draining hose outlet 200 in this way, for example, the washing / drying machine 1 When a drainage trap is installed in a waterproof pan or the like disposed at the installation location, the drainage hose 17 can be disposed at the first extraction position so that normal drainage can be performed.
Further, in the case where a drainage trap is not provided in a waterproof pan or the like, the drainage hose 17 is moved and arranged at the second take-out position, and the drainage trap is configured by the above-described height difference H1 of the drainage hose 17. it can. Thereby, it becomes possible to prevent the reverse flow of the odor with the drain trap.

Next, the operation of the washing / drying machine 1 of the present embodiment will be described in the case where the drainage hose 17 is arranged at the second extraction position to configure the drainage trap.
First, in a water supply process, a water supply electromagnetic valve or the like is opened by an ECU (not shown), and tap water or the like flows into the outer tub 5. At this time, the drain electromagnetic valve 110 of the drainage device 100 is demagnetized, and the valve body is closed. In FIG. 2, the tap water is illustrated to be poured into the inner tub 6, but actually, the tap water is poured into the outer tub 5 from between the inner tub 6 and the outer tub 5. Yes. A part of the tap water flows into the cooling and dehumidifying air passage 21, and the lint and the like adhering to the cooling and dehumidifying plate 22 are washed.

  Next, in the washing process, the washing / dehydrating drive device 10 is rotationally driven by the control of the ECU, and the rotary blade 30 is rotated. At this time, the rotary blade 30 performs rest, right rotation, and left rotation. Due to the rotation of the rotary blade 30, dirt adhering to the laundry 19 is eluted into the washing water. In the washing process, the drain electromagnetic valve 110 of the drainage device 100 remains demagnetized, and the washing water discharged from the outer tub 5 through the drain pipe k1 flows through the circulation pipe 124 from the horizontal pipe 120 through the branch port 123, and the circulation pump. The water is pumped up at P1 and supplied to the inner tank 6 again. When the washing process is performed for a predetermined time, most of the dirt adhering to the laundry 19 is eluted into the washing water.

Then, the process proceeds to the drainage process, and the ECU stops the rotary blade 30, opens the drainage electromagnetic valve 110 of the drainage device 100, and discharges the dirty washing water to the outside of the washing dryer 1.
At this time, the washing water (drainage) flows into the horizontal pipe 120 of the drainage device 100 from the drain pipe k1 and flows into the vertical pipe 130 from the horizontal pipe 120. Then, the washing water flows from the vertical pipe 130 to the drain hose 17 and is discharged from the second take-out position to the outside of the washing dryer 1.

  During such drainage, the drainage hose 17 is filled with washing water, and a drainage trap is configured between the drainage device 100 and the second extraction position. As a result, even if the drainage trap blocks the odor from the downstream side of the drainage hose 17, it is prevented from flowing back to the upstream outer tank 5 through the drainage device 100.

  When a predetermined time has passed and most of the dirty washing water is discharged to the outside, the process proceeds to a dehydration process, and the washing water contained in the laundry 19 is dehydrated. In the dehydration process, the drain electromagnetic valve 110 of the drainage device 100 remains open, and drainage continues through the drain trap.

  When the dehydration process is performed for a predetermined time, the process proceeds to the water supply process, the drain electromagnetic valve 110 of the drainage device 100 is closed, and a predetermined amount of tap water or the like is stored in the inner tank 6 as rinse water.

  In the rinsing step, the rotary blade 30 is rotated to rinse the laundry 19, and the detergent and dirt contained in the laundry 19 are eluted into the washing water. When the laundry 19 is rinsed for a predetermined time, the process proceeds to a drainage process, the rotary blade 30 is stopped, and the rinse electromagnetic valve 110 of the drainage device 100 is opened to drain the rinse water to the outside. At this time as well, even if odors rise from the downstream side of the drainage hose 17 or the like due to the action of the drainage trap by the drainage hose 17, this is suitably blocked.

In the drying process, the ECU closes the drain electromagnetic valve 110 of the drainage device 100 and starts the operation of the electric blower 23 and the heater Hp. As a result, the drying air heated by the heater Hp extracts moisture contained in the laundry 19 and then circulates from the drainage / exhaust port 5b by the drying air circulation system of the cooling / dehumidifying mechanism 20. In the process, the laundry 19 in the inner tub 6 is dried.
Also at this time, even if odors rise from the downstream side of the drainage hose 17 due to the action of the drainage trap by the drainage hose 17, this is suitably blocked, and the odor does not flow backward to the upstream side of the drainage device 100.

Below, the effect acquired in this embodiment is demonstrated.
(1) In the drain hose outlet 200, the drain hose 17 can be positioned at the first and second extraction positions, and the drain hose from which the drain trap has been removed can be taken out by using the first extraction position. In addition, by setting the second extraction position, it is possible to take out the drain hose to which the drain trap is added.
Therefore, when a drainage trap is installed in a waterproof pan or the like disposed at the place where the washing / drying machine 1 is installed, the drainage hose 17 is disposed at the first extraction position so that normal drainage is performed. be able to.
On the other hand, when the drainage trap is not installed in the waterproof pan or the like, the drainage hose 17 is moved to the second take-out position, and the drainage trap is configured by the height difference H1 of the drainage hose 17. Can do. Thereby, even when the drainage trap is not provided in the waterproof pan or the like, the drainage trap simply configured on the washing / drying machine 1 side can suitably prevent the back flow of odor.
Therefore, the drain trap can be easily added or removed in accordance with the presence or absence of the drain trap at the installation site, and it is not necessary to consider whether or not the drain trap is installed at the installation site. Thereby, the washing dryer 1 excellent in installation property is obtained.
(2) Since the drainage trap can be configured as necessary using the existing drainage hose 17, it is not necessary to change the routing of the drainage hose 17, and the assembly and productivity are excellent. . Moreover, the installation space can be small, and the drain trap can be configured at low cost.
(3) Since the drain hose 17 is provided so as to be movable between the upper and lower two insertion holes 201, 202, the drain hose 17 can be easily positioned at the first extraction position or the second extraction position. Traps can be easily removed or added.
(4) The drainage hose 17 has flexibility that can be deformed into a flat shape, and can move between the two upper and lower insertion holes 201 and 202 through the communication portion 203 while being deformed into a flat shape. Therefore, it is possible to easily locate the first extraction position or the second extraction position, and it is possible to easily remove or add the drain trap.

Although the embodiment of the present invention has been described above, the present invention is not limited to the previous embodiment, and can be appropriately modified within the scope of the gist of the present invention.
For example, as shown in FIGS. 8 (a) and 8 (b), a detachable plate member 205 is provided at the drain hose outlet 200, and the first extraction position when the plate member 205 is turned upside down is provided. The insertion hole 206 may be formed at a position corresponding to the second extraction position, and the drainage hose 17 may be inserted and held in the insertion hole 206.

  According to such a configuration, the drain hose 17 can be easily positioned at the first extraction position or the second extraction position by replacing the top and bottom of the plate-like member 205 with respect to the drain hose outlet 200. Traps can be removed or added easily.

Further, as shown in FIG. 4, an overflow pipe 21 b may be connected to the vertical pipe 130 so that the overflow drainage discharged from the updraft 21 a or the like during water supply flows through the vertical pipe 130.
With this configuration, when the water level in the outer tub 5 rises due to some abnormality, the water supplied to the vertical pipe 130 of the drainage device 100 is drained through the overflow pipe 21b and is discharged from the drain hose 17 through the drain trap. Drained outside. Accordingly, the odor from the drainage hose 17 and the like is blocked by the drain trap and is prevented from flowing back into the overflow pipe 21b. In addition, at the time of abnormality, a water supply solenoid valve etc. are closed after predetermined time progress and water supply is stopped.
