Some of the drums 2 are provided with a door packing 23 that covers between the clothes input ports.
[0009]
[Problems to be solved by the invention]
However, in such a conventional drum-type drying and washing machine, troubles such as breakage of the door packing occur, and when replacing the door packing at the time of service, a great deal of labor is required. The reason for this is that it is necessary to fit the fitting groove 233 of the door packing over the entire circumference into the folded portion 42 at the rim of the water tank while expanding the door packing in the radial direction, which requires familiarity.
[0010]
Furthermore, when the balance weight is attached to the front part of the water tank, the gap between the balance weight and the door packing fixing portion is small. In order to insert the groove of the door packing into the folded part of the rim of the aquarium with the balance weight attached at the time of service, etc. It was particularly difficult to fit over. Also, when the fixing member is mounted, it is difficult to mount the fixing member because the space for the hand is small.
[0011]
Also, when the clothes are put and the drum is rotated on the inner peripheral surface near the water tank, the clothes rub the inner peripheral surface of the water tank side end of the door packing, and the door packing is worn due to friction with the clothing. In addition, there has been a problem that it is broken and leads to water leakage.

[0034]
FIG. 3 shows a detailed cross-sectional view of a connection portion between the door packing 23 and the water tank 4. The door packing 23 is internally fitted as a sealing material made of an elastic material such as rubber. Therefore, when the door 22 is closed, the sealing material is sandwiched between the peripheral edge of the door 22 and the inner peripheral edge 40a of the charging port 40, so that the watertightness of the outer box 1 and the water tank 4 is maintained. I have. Then, by forming a cylindrical portion between the door 22 and the water tank 4, a clothing input path 231 is formed.
[0035]
The end portion 232 of the door packing 23 on the water tank side has a U-shaped cross-sectional shape having a turn 232b in the outer case 1 direction over the entire circumference. On the other hand, a circumferential double rib 44 is formed on the peripheral edge 41 a of the clothes input port 41 of the water tank 4, and bosses 43 having screw receiving holes are provided at several places along the rib 44. FIG. 6 shows a front view of a connection portion of the water tank 4 with the door packing 23.
[0036]
The terminal portion 232 of the door packing 23 is fitted into the groove of the double rib 44 of the water tank 4, and the fixing member 27 having an inner edge having a rib that fits inside the folded groove 232 a of the terminal portion 232 is attached to the boss 43 of the water tank 4. , The door packing 23 is attached to the water tank 4, and the clothes input path 231 and the water tank input port 41 are connected in a watertight manner.
[0037]
In the actual assembling stage, the fixing member 27 is temporarily fitted in advance in the groove 232a of the U-shaped terminal portion 232 of the door packing 23, so that the door packing 23 and the fixing member 27 are integrated into Can be fitted between the circumferential double ribs 44 formed on the rim portion 41a. Thereby, when connecting and disconnecting the door packing 23 to and from the water tank 4, it is possible to work from the front, and even when there is little space for access around the rim 41a, it is difficult to perform unfamiliar work. Even a person can perform easy work.
[0038]
The conventional groove 233 (FIG. 18) for connecting the door packing to the water tank has a complicated shape and a narrow groove width, so that only a manufacturing method such as direct pressure can be used. This production method had a very poor productivity of 2-3 pieces per hour. However, when the terminal portion 232 has a simple U-shape as in the present embodiment, molding by injection becomes possible, thereby increasing the productivity of the door packing 23 to 6 to 10 pieces per hour. improves. Moreover, since the number of mold strokes can be reduced, mold investment costs can be reduced.
[0039]
In addition, even during molding, the useless amount can be reduced, which leads to a reduction in product unit cost. In addition, since it is not necessary to perform a heavy operation such as dividing the mold by hand at the time of release, it leads to labor saving. Furthermore, as mentioned earlier, the only way to increase productivity with direct pressure is to increase the number of mold faces, and the remodeling of the mold during design changes was very large, but it was necessary. Disappears. In addition, in the case of direct pressure, it is necessary to disperse the molding companies to some companies including the problem of delivery, so that it is difficult to ensure the quality, but the quality control becomes easy.
[0040]
Since the ribs 44 are formed on the outer wall surface of the water tank 4 and are thereby connected to the door packing 23, when the water tank 4 is formed of resin, the manufacture of the water tank is also facilitated. In the conventional configuration shown in FIG. 18, in order to provide the folded portion 42 at the rim portion 41 of the resin water tank, a slide structure of several divisions on the mold is required, and the mold becomes complicated, and the rim portion 41 is formed. The vicinity had to be a flat structure without protrusions. However, in the configuration of the present invention, it is possible to form the door packing attaching portion only by simple up / down punching, so that the structure of the mold is simplified, and the periphery of the clothing inlet 41 (the hatching in FIG. Any functional structure including the boss 43 can be formed in the (provided area).
[0041]
The fixing member 27 that fits inside the U-shaped groove 232a of the door packing 23 is formed of a material having an appropriate strength, such as a resin or a sheet metal. FIG. 3 shows an example in which the fixing member 27 is formed of resin. FIG. 4 shows an example in which the fixing member 27 is formed of sheet metal. In either case, the boss 43 provided on the front surface of the water tank 4 is used for screw fixing, and the vibration of the water tank 4 prevents the door packing 23 from coming off the water tank 4.
[0042]
FIG. 8 shows a modification of the resin fixing member. The fixing member 27 is reinforced by adding a circumferential rib 271 to the opposite side to the groove 232a and connecting the rib 273 to a flange portion 272 for screwing to the water tank 4. . By doing so, the section modulus can be easily increased even in a portion to which a load is applied, and the strength can be secured.
[0043]
The fixing member 27 surrounds the entire periphery of the door packing 23. However, the fixing member 27 may be a single member, or may have a configuration in which a plurality of pieces are connected to surround the entire periphery of the door packing 23. The single fixing member has a circumferential shape, and each of the plurality of pieces has an arc shape. FIG. 5 shows a front view of the fixing member 27 when the entire periphery of the door packing is surrounded by two members. When the terminal portion 232 of the door packing 23 is first fitted into the rib 44 of the water tank 4 and then the fixing member 27 is fitted into the groove 232a, the door packing is formed by a single circumferential fixing member. Although the groove 234 provided for the purpose of absorbing the vibration of 23 must be fitted while being deformed, the arc-shaped fixing member can be easily fitted into the groove 232a without deforming the groove 234.
[0044]
Further, in the case of the circumferential fixing member, although the inside is almost hollow, the size of the component is close to the size of the clothes input port 41, so both the mold and the molding machine become large, and the weight of the component increases. As you can see, large space is required for transportation and storage. Moreover, if the parts are made of resin, there is a possibility that a problem of warpage may appear. However, if the fixing member is formed into a plurality of pieces, such a disadvantage is solved.
[0045]
FIG. 7 is an enlarged view of the end portion 232 of the door packing 23. In the figure, (a) is a cross-sectional view, and (b) is a front view of the groove 232a viewed from the direction of the arrow A. The groove 232a is provided with a radially extending rib 238 for defining the position of the fixing member 27 in the direction along the groove 232a. In the case of a fixed member consisting of a plurality of pieces, its end is brought into contact with the rib 238. In the case of a single fixed member, a transverse groove is formed and the groove is fitted into the rib 238. The position of the fixing member is fixed. Thereby, the door packing 23 and the fixing member 27 can be aligned with respect to all the bosses 43 provided in the water tank 4.
[0046]
Since the air duct 131 and the circulation hose 101 are connected to the door packing 23, the mounting angle is important. However, in the related art, a slight misalignment is made of a rubber part that absorbs elastically. However, it was not possible to say that the assembly was accurate because the operator was required to manually adjust the angle by hand. As described above, when the rib 238 is provided to perform positioning between the door packing 23 and the fixing member 27, a method of assembling the door packing 23 and the fixing member 27 in advance and then fixing the door packing 23 and the water tank 4 is adopted. This can be easily realized, and the door packing 23 can be attached to the water tank 4 with high accuracy.
[0047]
Here, the position of the fixing member 27 is defined by the rib 238 provided inside the groove 232a. However, for example, a protrusion is formed outside the groove 232a, and a recess is formed in the fixing member. May be engaged to define the position of the fixing member 27.
[0048]
In order to further facilitate the positioning of the fixing member 27 with respect to the water tank 4, the fixing member 27 may be provided with a portion that engages with the boss 43. FIG. 9 shows an example in which a rib 274 having a shape surrounding the boss 43 is provided on the flange portion 272 of the fixing member 27. Thus, the radial and circumferential positions of the door packing 23 are defined.
[0049]
At the time of attachment, the fixing member 27 is temporarily fitted into the groove 232 a of the door packing 23, and the integrated member is fixed to the water tank 4. At this time, by aligning the rib 274 formed on the flange portion 272 with a position surrounding the boss 43 on the front surface of the water tank, all the component positions are determined at once. Then, screwing is performed at that position.
[0050]
FIG. 10 shows, as another example, a configuration in which a pin 275 is provided on the fixing member 27 and a receiving portion 45 to which the pin 275 is fitted is formed on the front surface of the water tank. In addition, although not shown, the configuration may be the same as that of the present embodiment, but may be reversed, or may be configured to fit with ribs and grooves. The door packing 23 can be easily attached to the water tank 4 in the same manner as the above procedure.
[0051]
Clothing rotating with the drum 2 rubs on the inner peripheral surface of the door packing 23 near the water tank 4. For this reason, the door packing 23 may be worn out due to long-term use, and may be damaged due to vibration caused by rotation of the drum. Embodiments that take measures to address this problem are described below. In the following embodiments, the entire configuration of the drum-type drying and washing machine and the method of attaching the door packing to the water tank are the same as those in the above-described embodiments, and redundant description will be omitted.
[0052]
FIG. 11 shows a cross-sectional view of a connection portion between the door packing 23 and the water tank 4 according to the second embodiment. A resin coating 29 is applied to the inner peripheral surface of the door packing 23. The coated resin is excellent in smoothness and abrasion resistance, for example, like Teflon, and the coating 29 is hardly damaged and protects the door packing 23 for a long time. Here, an example in which the coating 29 is applied to the entire inner surface of the door packing 23 has been described, but it is also possible to coat only the portion close to the water tank 4.
[0053]
FIG. 12 is a cross-sectional view of a connection portion between the door packing 23 and the water tank 4 according to the third embodiment. A resin sheet 30 having excellent smoothness and abrasion resistance is adhered to the inner peripheral surface of the door packing 23.
[0054]
FIG. 13 shows a cross-sectional view of a connection portion between the door packing 23 and the water tank 4 according to the fourth embodiment. A cylinder 31 made of a resin having excellent smoothness and abrasion resistance or a rustproof metal plate is fitted in the door packing 23.
[0055]
FIG. 14 is a cross-sectional view of a connection portion between the door packing 23 and the water tank 4 according to the fifth embodiment. In each of the above embodiments, the door packing 23 is formed of a homogeneous material. However, the door packing 23 of this embodiment is an integrally molded product of two types of materials, and the materials are the water tank 4 side and the outer box 1 side. And different. Specifically, a relatively hard and highly wear-resistant material is used for the water tank side 236, and a relatively soft and highly elastic material is used for the outer box side 237 including the groove 234 for absorbing vibration. 1 to prevent wear of the door packing 23 while reducing transmission of vibration.
[0056]
FIG. 15 is a cross-sectional view of a connection portion between the door packing 23 and the water tank 4 according to the sixth embodiment. In the present embodiment, when the door 22 is closed, the inner surface 221 slightly enters the inside of the water tank 4 slightly beyond the clothing input port 41 so that the side surface 222 is parallel to the inner surface of the door packing 23. It is configured. Since the clothes in the rotary drum 2 are prevented from entering the door packing 23 by the inner surface 221 of the door 22, the clothes do not rub the inner surface of the door packing 23 and the door packing 23 does not wear. The inner surface 221 of the door 22 may be configured to enter the inside of the rotary drum 2.
[0057]
The gap between the side surface 222 of the door 22 and the inner surface of the door packing 23 is preferably small, and is set to 10 mm or less. In addition, if the portion 223 where the inner surface 221 and the side surface 222 of the door 22 continue has a large radius of curvature, clothes can easily enter between the door 22 and the door packing 23. Therefore, it is desirable that the radius of curvature be as small as possible. Here, in order to be able to observe the inside of the rotating drum 2, a glass molded product is used for the inner surface 221 of the door 22. It is the minimum value possible in glass molding. For example, in the case of glass having a thickness of 6 to 7 mm, the inner radius of curvature is set to 0.5 mm, and the outer radius of curvature R is set to 6.5 to 7.5 mm.
[0058]
In the first to fifth embodiments, the door packing 23 is formed in a cylindrical shape in order to prevent clothes rotating together with the rotating drum from colliding with the inner surface of the door packing 23 or the cylinder 31 fitted therein. However, in the sixth embodiment, since the clothing does not enter the door packing 23, the door packing 23 is not necessarily required to have a cylindrical shape. For example, the door packing 23 is formed in a cylindrical shape having a substantially square cross section and adjacent surfaces gently connected to each other. In accordance with this, the outer case 1 and the garment charging ports 40 and 41 of the water tank 4 are formed into substantially square shapes without sharp corners. The door 22 may be formed into a substantially quadrangular prism in which the side surfaces of the door 22 are smoothly connected. In this way, the cross section of the clothing introduction path 231 can be widened, so that the clothes can be easily taken in and out, and there is no possibility that the rotating clothing is caught by the door.
[0059]
Even in such a configuration, the end portion 232 of the door packing 23 is formed to have a substantially U-shaped cross-section having a folded portion 232b toward the outer box, so that the door packing 23 can be attached to the water tank 4 extremely easily. Can be. In addition, since there is no freedom in the circumferential direction in the case of the cylindrical door packing, the positioning of the door packing with respect to the water tank is further simplified, and the mounting operation is further facilitated.
[0060]
