The plurality of holes 10a are formed so that water can flow out and flow in between the water tank 9 and the rotary drum 10 during washing. Inside the rotary drum 10, a plurality of baffles 11 for stirring clothes are provided to protrude inward. The rotary drum 10 is rotationally driven in the forward and reverse directions by the motor 12 mounted on the back side of the water tank 9. Sink 9 The piping connected to the water supply pipeline 13 and the drain pipeline 14 is used to supply and drain water in the water tank 9 by controlling the water supply valve and the drain valve not shown.

In addition, during the washing operation, the laundry that has been stored in the rotating drum 10 is taken up by the baffle 11 and peeled from the baffle 11 at a predetermined position to fall toward the water surface accumulated in the rotating drum 10 . This is done to perform the so-called "slap laundry".

The rotary drum 10 is provided with a drum opening portion 10b on which the laundry can enter and exit on the front side. The main body 1 is provided with a curved front panel member 5 on the front side. An opening member 15 is attached to the front panel member 5. The opening member 15 has an opening 15 a (also referred to as a front opening) before the laundry enters and exits. The drum opening 10b and the front opening 15a are arranged to face each other. The front opening 15a of the opening member 15 is opened and closed by a lid body 16 having an inner cover 16a having a hard transparent material (for example, glass material) inside.

The front panel 17 covers the front side with the front panel member 5. In addition, the inner cover 16a protrudes inside the rotary drum 10 more than the front panel opening 17a.

In addition, the water tank opening 9 a of the water tank 9 is located inside (rear side) of the opening member 15 and is arranged to face the front panel opening 17 a of the front panel 17. The space between the water tank opening 9a of the water tank 9 and the front panel opening 17a of the front panel 17 is connected and sealed by a gasket member 18 made of an elastic material such as rubber. Thereby, the situation that water leaks from the water tank 9 into the body 1 can be prevented.

3A is an enlarged cross-sectional view of the periphery of the pad member of the drum-type washing machine in Embodiment 1 of the present disclosure. 3B is a partially enlarged cross-sectional view of the pad member of the drum-type washing machine. 4A is a schematic view of the rib viewed from the direction A in FIG. 3A. 4B is a schematic view of the rib viewed from the direction B in FIG. 3A.

In FIG. 3A, the cushion member 18 includes a cylindrical portion 18b and a bulging portion 18c that extend rearward from the front panel opening 17a (including the vicinity of the front panel opening 17a) of the front panel 17, The swelled portion 18c is swelled to the outer peripheral side by folding forward and outward from the rear end of the cylindrical portion 18b, and is connected to the water tank opening 9a. The lip portion 18a formed on the inner periphery of the front end portion of the cylindrical portion 18b protrudes from the inner peripheral side of the front panel opening 17a of the front panel 17 and contacts the outer peripheral surface of the inner cover 16a when the cover 16 is closed And sealed. This prevents water and steam from leaking from the outer periphery of the cover 16. As shown in FIG. 3B, the lip portion 18a is, for example, set the height c from the inner surface of the cylindrical portion 18b to 9 mm and the thickness d to 3 mm.

Furthermore, as shown in FIG. 3A, the pad member 18 is provided with a rib portion 18 d on the side of the cylindrical portion 18 b closer to the water tank opening portion 9 a than the lip portion 18 a. For the rib portion 18d, for example, the height e at the center portion from the inner surface of the cylindrical portion 18b is set at 12 mm, the thickness f at the tip portion is set at 11 mm, and the thickness g at the root portion is set at 14 mm. The height e (12 mm) of the rib 18d is set when there is a space between the inner cover 16a and the inner cover 16a so as not to contact the inner cover 16a when the cover 16 is closed Gap height. In addition, the rib 18d is provided at a distance h (for example, 10 mm) from the lip 18a.

That is, the thickness of the rib 18d of the cushion member 18 is set to be thicker than the thickness of the lip 18a, and the height of the rib 18d is set to be higher than the height of the lip 18a. In addition, the rib portion 18d is configured so as not to contact the inner cover 16a when the cover body 16 is closed. Here, the minimum gap i between the front end of the rib 18d and the inner cover 16a is set to 3 mm in this embodiment. Thereby, it is possible to prevent the rib 18d from causing a sense of incongruity to the user when the lid 16 is opened and closed, or from affecting the sealing performance between the lip 18a and the inner lid 16a.

Furthermore, the rib portion 18d does not need to be provided on the entire circumference of the cylindrical portion 18b of the packing member 18. As shown in FIG. 4B, when the cover 16 is closed, it may be provided within a range of α (for example, 35°) to the left and right of the center line in the lower semicircular portion where the laundry may be caught.

In addition, as described above, in this embodiment, although the rib 18d is at the center, the thickness f of the front end is set to 11 mm, but as shown in FIG. The thinner, and the thickness of the left and right α portions is set to k (for example, 6 mm). As a result, the user can reduce the sense of discomfort and pressure in the rib 18d.

In addition, the lowermost portion (including the substantially lowermost portion) of the central portion (including the substantially central portion) of the rib portion 18d is provided with a drain hole 18e communicating from the front to the rear (see FIGS. 3A, 4A, and 4B). With this, it is possible to prevent a state where water is accumulated between the lip portion 18a and the rib portion 18d as it is after the washing is completed. Furthermore, the cylindrical portion 18b is provided with a concave groove 18f before and after the drain hole 18e. By this, the water accumulated between the lip 18a and the rib 18d can pass through the drain hole 18e and the concave groove 18f flow smoothly toward the water tank 9 through the bulging portion 18c. This prevents water from accumulating between the lip portion 18a and the rib portion 18d after washing, and prevents water from adhering to the washing clothes when the washing clothes are taken out after washing.

In addition, regarding the lip portion 18a, the size such as the thickness may be appropriately determined by verifying the relationship between the sealability with the inner cover 16a and the opening/closing force of the cover body 16, or the durability.

For the drum-type washing machine configured as above, the operation and function thereof will be described below using FIGS. 5A and 5B.

FIGS. 5A and 5B are state diagrams of the drum-type washing machine of the present embodiment when a part of the laundry is sandwiched between the outer periphery of the inner cover and the lip of the pad member when the operation is started.

At the beginning of the washing step, the user puts the laundry 19 into the rotating drum 10. At this time, the laundry is accidentally sandwiched between the inner cover 16a of the cover 16 and the cushion member 18, and when the user has started the operation in this state, the laundry 19 is caught between the inner cover 16a and the liner In the state between the pad members 18, the washing laundry 19 rotates as the shutter 11 provided in the rotary drum 10 rotates.

As shown in FIG. 5A, the laundry 19 gradually generates a twisted portion 19a as the rotary drum 10 rotates. At this time, the twisted portion 19a is generated inside the rib portion 18d which is closer to the laundry 19 and has a higher height than the lip portion 18a. Also, the twisted portion 19a is about to entangle the rib 18d. However, as shown in FIG. 5B, since the thickness of the rib 18d is thick, the shearing force due to twisting does not act. Then, the twisted portion 19a gradually becomes larger, and makes the washing The laundry 19 itself is gradually drawn into the rotary drum 10 and is separated from between the inner cover 16a and the cushion member 18. As a result, it is formed that the washing laundry 19 can be stirred normally in the rotary drum 10.

Furthermore, in this embodiment, the height e (12 mm) of the rib 18d from the inner surface of the cylindrical portion 18b is set to be higher than the height c (9 mm) of the lip 18a from the inner surface of the cylindrical portion 18b Higher, but not limited to this. Even if the height e of the rib 18d from the inner surface of the cylindrical portion 18b is the same as the height c of the lip 18a from the inner surface of the cylindrical portion 18b, the shape of the inner cover 16a (inclination toward the center Degree) to obtain the same effect as described above.

In addition, since the height e of the rib 18d from the inner surface of the cylindrical portion 18b is set to 5mm≦e<15mm, as long as the minimum gap i between the front end of the rib 18d and the inner cover 16a is set to 0mm<i ≦10mm, the chance of the twisted portion 19a exceeding the front end of the rib 18d and reaching the lip 18a can be further reduced.

However, when the minimum gap i between the front end of the rib 18d and the inner cover 16a is set to 5 mm<i≦10 mm, the height e from the inner surface of the cylindrical portion 18 b can be made 5 mm≦e<10 mm . At this time, although the rib portion 18d can be made less conspicuous, on the other hand, the torsion portion 19a exceeds the front end portion of the rib portion 18d, and the possibility that the torsion portion 19a of the laundry 19 wraps around the lip portion 18a becomes higher .

Therefore, by setting the minimum gap i between the front end of the rib 18d and the inner cover 16a to 0 mm<i≦5 mm, the twisted portion 19a can be sandwiched between the front end of the rib 18d and the inner cover 16a. With this, it is possible to reliably prevent twisting The rotating portion 19a reaches the lip portion 18a, and the washing laundry 19 can be prevented from getting caught in the lip portion 18a. As a result, it is possible to prevent the gasket member 18 from falling off and breaking, and it is possible to prevent the occurrence of serious water leakage.

As described above, in this embodiment, the cushion member 18 has the cylindrical portion 18b extending rearward from the front opening 15a (including the vicinity of the front opening 15a), and the bulging portion 18c by the cylindrical portion 18b The rear end of the folds forward and outward and swells to the outer peripheral side and is connected to the water tank opening 9a; the lip 18a is provided at the front end of the cylindrical portion 18b and is connected to the inner cover 16a when the cover 16 is closed The abutment; and the rib portion 18d is provided on the cylindrical portion 18b closer to the water tank opening portion 9a side than the lip portion 18a. The rib 18d is set to be thicker than the thickness of the lip 18a, and the height is higher than the height of the lip 18a. Moreover, the rib 18d does not contact the inner cover 16a when the cover 16 is closed. When the laundry 19 has been activated by accidentally sandwiching the laundry 19 between the inner cover 16a and the cushion member 18, the laundry 19 will be caught in the rib 18d closer to the lip 18a, and It is intended to draw the cushion member 18 into the rotary drum 10 with a strong force. In this embodiment, since the thickness of the rib 18d is set to be thick, the laundry can be detached from the lip 18a and the rib 18d when the laundry 19 does not sufficiently wrap around the rib 18d. With this, it is possible to prevent the cushion member 18 from falling off or cracking and to prevent serious water leakage.
