If the locking of the latch 21 is released, the detection unit is moved in the direction of the white arrow (release direction) in the figure by a pushing member (not shown), and the detection of the door closing is released.

The door sag preventing portion 220 constituting the positioning means is provided at the outer peripheral portion of the frame 190 as shown in Figs. 4 (b), 8 (a), and (b). The convex portion 220 is located closer to the pivot side than the center of the door 25, and is disposed at a position on the lower side in the circumferential direction of the seat plate. The convex portion 220 is formed integrally with the frame body 190 and includes a tapered surface 227.

The door 25 is in contact with the front panel 12 through a tapered surface 227 as shown in FIGS. 9 (a) and 9 (b). The tapered surface 227 is opposed to the loading surface of the drum-type washing machine 1. It is tilted. Therefore, by being lifted by the tapered surface 227, it is possible to properly close the input port. In the state, it is positioned at the opening edge of the input port.

The latch 21 is configured to be inserted into the door 25 without being in contact with the guide portion 262c on the lower side of the latch receiving portion 260 when the door 25 is positioned in the same manner as described above. Into the latch receiving portion 260.

The door glass 225, as shown in Figs. 6 (a) and 8 (a), has a slightly round hat shape in cross section, and is pressed by the flange portion formed at the peripheral portion by the fixing cover 226. It is held on the frame 190 and is held between the frame 190 and the fixed cover 226 so as to be unable to fall off.

An upper surface of the door glass 225 is formed with an inclined surface. This inclined surface functions to appropriately guide the warm air blown out through the opening of the outer tank into the drum.

Next, the function when the door is closed will be described.

For example, when laundry or the like is stored in the drum through the insertion port during washing, if the door 25 is pushed by hand or the like and is operated in a direction to close the door 25, the door 25 is pivoted via a pivot Instead, it is rotated and approaches the opening edge of the input port in a state where the input port is closed. In this way, the tapered surface 227 of the door sag prevention portion 220 of the door 25 provided on the side closer to the pivot than the latch 21 is in contact with the front panel 12, because the tapered surface 227 is relatively Since the mounting surface of the drum-type washing machine 1 is inclined, the door 25 is lifted by the tapered surface 227. Accordingly, while the door 25 is being closed, the input port is positioned at the opening edge portion of the input port in a state where the input port is properly closed.

Here, it is assumed that the door sag prevention unit 220 is in a case where the door 25 has a position that sags more than a specific position due to external downward forces acting on the opened door 25. It is in contact with the opening edge of the input port of the front panel. In this way, the tapered surface 227 of the door sag prevention portion 220 is lifted so as to climb up the slope on the opening edge. As a result, the positional displacement of the door 25 is corrected, and the positional displacement of the latch 21 with respect to the latch receiving portion 260 is corrected.

Thereafter, when the door 25 is brought closer to the opening edge portion of the input port, the latch 21 is inserted into the latch receiving portion 260. In this case, the latch 21 is inserted into the latch receiving portion 260 in a state where the door 25 is positioned by the positioning means. Therefore, at the time of insertion, the front end of the latch 21 is inserted. The 21m series does not contact the guide portion 262c on the lower side of the latch receiving portion 260, and realizes smooth insertion.

After the insertion, the front end portion 21m of the bolt 21 is moved to the locking receiving portion 266 side, and the front end portion 21m is locked at the locking receiving portion 266. With this, the detection section 265a of the door lock detection section 265 is pushed by the front end portion 21m, and the door lock detection is detected by the door lock detection section 265. At this point, the front end portion 21m of the latch 21 is smoothly moved to the latch receiving portion 266 side after being inserted into the latch receiving portion 260. This is because, at the time of insertion, the front end portion 21m of the latch 21 does not contact the lower guide portion 262c and the like, and the front end portion 21m is not subject to the same resistance as when abutted, Therefore, the degree of freedom of movement of the 21 m of the front end portion is ensured. With this, the door closing detection by the door lock detection unit 265 can be reliably performed.

According to the drum-type washer-dryer of the present embodiment described above, the positioning means (door sagging prevention part 220) for correcting the positional deviation of the latch 21 with respect to the latch receiving part 260 is used. It is set at a position different from the latch receiving part 260, and the two functions of correcting the position shift of the latch 21 and the detection function of the door lock are set separately. While the positional deviation is appropriately corrected by the positioning means, the door closing detection is surely performed by the latch receiving portion 260 as well.

The positioning means is constituted only by the door sag prevention portion 220 provided at the door 25, and a function of correcting the positional deviation of the latch 21 can be obtained at a low price. In addition, as the configuration of the positioning means, it is only necessary to provide the door sag prevention portion to the frame body 190. Therefore, the system does not require a large design change of the washing machine to realize the positional deviation of the latch 21 The function moved as a correction.

Since the positioning means is disposed at a lower side than the pivot, the positioning means is shielded by the door glass 225 and the like, and it is difficult for the user to see the door sag prevention portion 220. Therefore, there is no case where the design of the door 25 or the like is damaged.
