  FIG. 4 is a perspective view of the main part of the drum type washing machine according to the embodiment of the present invention, FIG. 5 is an exploded perspective view of the main part of the drum type washing machine, and FIG. 6 is a locking member of the drum type washing machine 7 is a cross-sectional view of the main part around the locking member of the drum type washing machine, FIG. 8 is a partial cross-sectional view of the main part around the biasing spring of the drum type washing machine, FIG. FIG. 2 is a cross-sectional view of an essential part around an urging spring of the drum type washing machine.

  4, 5, 6, 7, 8, 9, the decorative panel 25 can be pivoted open and closed freely with the pivot 26 provided at the lower part of the main body as a fulcrum and engaged with the front frame 5 in the closed state A locking arrangement is provided to maintain the closed position.

    The locking mechanism will be described below. The substantially U-shaped holding portions 27a and 27b are formed on the upper portion of the decorative panel 25, and the locking member 28 is attached to the holding portions 27a and 27b. The locking member 28 has locking claws 29 and shaft portions 30a and 30b on both sides of the locking claw 29. The shaft portion 30a is a holding portion 27a, and the shaft portion 30b is a holding portion 27b. It is loosely fitted freely. By the above configuration, the locking configuration is configured.

  The locking structure is disposed at two positions close to the left and right ends of the decorative panel 25, and as described later, the locking claws 29 of the locking member 28 are in the front in the closed state of the decorative panel 25. It is configured to be engaged with the lower side portion of the part frame body 5.

The locking member 28 is provided with an urging spring 31 formed of a coil spring having an arm 32 and an arm 35 in order to turn the locking claw 29 up and down. Is inserted into the shaft portion 30b, and as shown in FIG. 9, the arm 32 on one end side is housed in the groove 33 formed on the side surface of the locking member 28 and attached by the locking member 28. In a state where the arm 32 is attached to the locking member 28, the shaft portions 30a and 30b of the locking member 28 are engaged with the holding portions 27a and 27b from above. At this time, the locking claw 29 is engaged below the stopper 34 formed in the back direction of the main body 1 between the holding portions 27a and 27b, and the arm 35 on the other end side of the biasing spring 31 is While being bent against the biasing force, the notch portion 36 of the decorative panel 25 is passed through and set in the hook portion 37.

  As shown in FIG. 8, the arm 35 sets the biasing spring 31 to the hook portion 37 while being deformed from the free state, so the locking member 28 is biased in the direction of raising the locking claw 29 by the arm 32. And the rotation is stopped by hitting the stopper 34. That is, the locking member 28 is always biased downward in the main body 1, that is, in the engaging direction of the holding portions 27a and 27b, by the reaction force of the arm 35 and the reaction force of the stopper 34. Protrusions 40 a and 40 b are integrally formed at both ends of the stopper 34 and cover up to the vicinity of both side surfaces of the locking member 28.

  After the locking member 28 and the biasing spring 31 are set on the decorative panel 25 as described above, the upper cover 42 is fixed to the decorative panel 25.

  By attaching the upper cover 42, the shaft portions 30a, 30b do not come off from the holding portions 27a, 27b, and even if the decorative panel 25 is open, the biasing spring 31 can not be seen. However, the locking claws 29 project from the top cover 42 in function. Therefore, as described above, by integrally forming the protrusions 40a and 40b in the vicinity of both side walls of the stopper 34 of the locking member 28, the locking member 28 is protected so as not to touch and the arm 32 is not visible nor touched. It is like that.

  FIG. 7 shows a state in which the locking claw 29 is engaged with the lower side of the front frame 5 when the decorative panel 25 is in the closed state. The lower side of the front frame 5 is at a position where the open / close lid 9 can be seen.

  When closing the decorative panel 25, the slope 50a on the back side of the locking claw 29 abuts on the slope 51a on the near side of the lower side of the front frame 5, resisting the biasing force of the biasing spring 31, The member 28 is rotated clockwise in FIG. 7 to ride over the lowest point of the slope 51a. After passing over the lowest point, the slope 51b on the front side of the locking claw 29 is pushed by the biasing force of the biasing spring 31 along the slope 51b on the back side of the lower side of the front frame 5, The stop member 28 rotates counterclockwise and stops at the closed position.

  When the decorative panel 25 is opened, the slope 50b descends the slope 51b against the biasing force of the biasing spring 31, and the locking member 28 rotates clockwise in FIG. 7 to the lowest point of the slope 51b. Overwhelm. After passing over the lowest point, the slope 50a moves away from the slope 51a, and the locking member 28 rotates counterclockwise by the biasing force of the biasing spring 31 and stops against the stopper 34.

  By this, the strength of the biasing force of the biasing spring 31 causes changes in the opening force and the closing force of the decorative panel 25.

  The locking claw 29 is biased by the biasing spring 31 so as to press the lower side of the front frame 5 from the bottom to maintain the closed state. In the engaged state, the stopper 34 and the locking member 28 are provided with a gap δ so as not to abut on the engaging portion of the body 5 without being weakened.

By providing the gap δ between the stopper 34 and the locking member 28, even if the size of the decorative panel 25 varies slightly, that is, even if the positions of the holding portions 27a and 27b change downward, the dimension of the gap δ Since only the contact with the stopper 34 does not occur, the biasing force transmitted to the engaging portion does not decrease, and the decorative panel 25 can be kept stable in the closed state.

  When the size of the decorative panel 25 varies to a large extent, the engagement claw 29 is engaged in a slightly depressed state, so that the biasing force of the biasing spring 31 in the engaged state is increased. However, for example, the spring constant of the biasing spring 31 can be reduced, and the setting angle of the arm 35 can be set large. According to this configuration, even if the angle of the arm 35 in the engaged state is varied due to the dimensional variation of the decorative panel 25, it is sufficiently smaller than the set angle, so the variation of the biasing force of the locking claw 29 is slight Can be reduced to

  The decorative panel 25 is held in the closed state for a long time even during normal use and non-use, but when the opening force is weak in the closed state, that is, the biasing force of the engaging portion is weak, for example, during dewatering operation Due to the vibration of the main body that occurs, the cosmetic panel 25 may be opened, or the cosmetic panel 25 may be opened due to the impact of opening and closing the open / close lid 9. In addition, even if the decorative panel 25 is not opened, if the engagement of the locking claws 29 is incomplete, the step between the open / close lid 9 and the decorative panel 25 becomes uneven, and the appearance quality is degraded. There is also a problem.

  In addition, since lint is collected in the drainage filter 22 each time it is used, it is necessary to clean the collected lint. When cleaning the drainage filter 22, as shown in FIG. 4, the decorative panel 25 is opened, the drainage filter 22 exposed from a part of the inner cover 43 is taken out, lint is removed, and then stored in the filter case 21. Then, the makeup panel 25 is returned to the closed state again. If a high opening force and closing force are required when opening and closing the decorative panel 25, the usability becomes poor.

  As described above, in the engaged state, the stopper 34 and the locking member 28 contact each other such that the biasing force is transmitted to the engaging portion of the locking claw 29 and the front frame 5 without being weakened as described above. The gap δ is provided so as not to contact, and further, the spring constant of the biasing spring 31 is reduced, the setting angle of the arm 35 is set large, and the variation of the biasing force is reduced. Even if there is a problem, it can be solved by suppressing fluctuations in the opening and closing forces to a level that does not cause any problems.

  Further, as shown in FIG. 1, the opening / closing lid 9 sets the width to a width substantially equal to the width W of the main body 1, and the lower width of the opening / closing lid 9 is the same as the opening / closing lid 9. A decorative panel 25 set to a width substantially equal to the width W is provided so as to be openable and closable. Thus, only one dividing line 55 can be provided between the open / close lid 9 and the decorative panel 25. As a result, the front surface of the main body 1 becomes flat and can be configured to be in harmony with the installation space.

  Since the locking configuration of the decorative panel 25 to the front frame 5 is provided at two locations close to the left and right ends, opening and closing is possible even when the position fluctuates in the front-rear direction due to the influence of warpage of parts The step in the front-rear direction with the lid 9 can be further reduced.

  Also, by applying a biasing force of the biasing spring 31 firmly so that the position of the locking claw 29 does not shift due to the vibration during dehydration or the shock of opening and closing the open / close lid 9 vigorously, the cosmetic panel 25 Position in the front-rear direction of the

As described above, in the present embodiment, the filter case 21 in which the drainage filter 22 for collecting thread waste and the like is accommodated is covered from the front side, and can be pivotably opened and closed by the pivot portion 26 at the lower part of the main body 1 The decorative panel 25 provided on the rear side is configured to have a lateral width substantially the same as the lateral width of the main body 1 and has a locking member 28 engageable with the lower side of the front frame 5 at the top and locking in the closed state The member 28 is biased to engage with the front frame 5 by the biasing spring 31, so that the dividing line seen on the front of the product is only one horizontal line at the upper end of the decorative panel 25. It is possible to improve the quality.

  In addition, the locking member 28 has a locking claw 29 that engages with the front frame 5 and a shaft that rotatably engages with the substantially U-shaped holding portions 27 a and 27 b formed on the decorative panel 25. The biasing spring 31 has a cylindrical portion 56 and arms 32 and 35 at both ends. The cylindrical portion 56 is inserted into the shaft portions 30a and 30b, and one end of the arm 32 is engaged. By inserting the groove 33 formed on the side surface of the stop claw 29 and engaging the arm 35 at the other end with the hooking portion 37 of the decorative panel 25, the user touches the arms 32 and 35 to deform it. As a result, it is possible to prevent the falling off and the falling off, and the engagement of the decorative panel 25 to the main body 1 can be reliably maintained.

  The drum-type washing machine according to the present invention can improve the design by reducing the dividing line between parts seen in front of the product to only one horizontal line at the upper end of the decorative panel. By appropriately setting the ineffective force of the biasing spring for the decorative panel, the engagement of the decorative panel with the main body can be reliably maintained, and therefore, other washing machines having a decorative panel that can be opened and closed on the front of the main body Applicable to
