Prepare.

  The drum-type washing machine 1 is a water supply means (not shown) for supplying washing water to the outer tub 4, a detergent box 12 for supplying detergent, and fiber waste detached from the laundry 14 in the drying process. A drying filter 17 that captures lint and an operation panel 11 on which operation buttons such as a washing start button are arranged are arranged.

  The outer tub 4 has a bottomed cylindrical shape having an opening on the front panel 10 side, and is elastically supported by the suspension 2 so that the central axis thereof is inclined with respect to the horizontal plane of the base 3.

  The rotary drum 5 has an opening on the front panel 10 side, is rotatably supported coaxially inside the outer tub 4, and is driven by a drive motor (not shown) provided on the back surface of the outer tub 4. Rotate by force.

  The suspension 2 has a function of reducing vibration during rotation of the rotating drum 5 by using an elastic force of a spring and a damping force of, for example, enclosed oil.

  The drying means is a means for drying the laundry 14 by operating during drying, and includes a fan 18, a heater 25, and a dehumidifier 20. The fan 18 and the heater 25 are disposed on the outer tub 4. The dehumidifier 20 is disposed outside the bottom wall of the outer tub 4 at a position shifted from a motor (not shown). The dehumidifier 20 includes a cooling pipe 20a through which a low-temperature fluid such as tap water flows.

  When the fan 18, the heater 25, and the dehumidifier 20 are activated during drying, the air from the fan 18 is heated by the heater 25 and then sent into the rotating drum 5 through the vent hole 4 a of the outer tub 4. It is supposed to be. Next, the air is sent from the rotating drum 5 to the dehumidifier 20 through the vent hole 4b of the outer tub 4, and after dehumidifying by the dehumidifier 20, returns to the fan 18 and circulates. .

  The lid 7 is pivotally supported so as to open and close the opening 6, and is opened in the direction of the arrow from the closed state shown by the solid line in FIG. 14 in and out. A spring (not shown) is provided on a shaft support portion that opens and closes the lid body 7, and applies a force in a direction to open the lid body 7 to open the lid body 7. When the lid body 7 is in an open state at a predetermined angle or more, the lid body 7 is urged further in the opening direction by the force of the spring, and when the lid body 7 is in an open state at a predetermined angle or less, The cover body 7 is configured to be biased in the closing direction by the weight of the cover body 7.

  In the closed state, the lid body 7 has a function of sealing the bellows 9 (seal member; see FIG. 4) disposed in the opening 6 and having a sealing function to make the inside of the outer tub 4 watertight.

  The lock means 15 holds the watertight closed state so that the lid body 7 is not opened to be opened, and is switched between holding and releasing the closed state in conjunction with the pushing operation of the push button 16. Execute.

  After releasing the holding function of the locking means 15, the lid body 7 is opened and opened, and the laundry 14 is put into the rotary drum 5 through the opening 6, or the laundry 14 that has been washed and dried is removed. Or take it out. When the holding function of the lock means 15 is released, a force for moving the lid body 7 to the position of the broken line portion is applied by a repulsive force of a hinge portion (not shown) that pivotally supports the lid body 7.

  Here, as shown in FIG. 8, the lock unit 15 performs an operation of locking or releasing between the operation lever 31 and the latch portion 32 received by the lid body 7 in conjunction with the operation lever 31. A locking lever 33 and a spring 34 that presses the locking lever 33 in the moving direction are provided. Connected to the operating lever 31 is a tip of a connecting rod 19 that moves in conjunction with a pushing operation of the push button 16 (see FIG. 1) via a connecting portion 31a.

  A pin 39 received also by the locking lever 33 is in slidable contact with an inclination 40 provided on the operation lever 31. As a result, when the connecting rod 19 moves up and down in conjunction with the pushing operation of the push button 16, the locking lever 33 locks the latch portion 32 of the lid 7 (FIG. 8A) or opens (FIG. 8 (FIG. 8). b)), and the switching between holding and releasing the closed state is executed.

  Further, as shown in FIG. 1, the latch portion 32 of the present invention is on the inner side of the lid body 7 (the side located on the rotating drum 5 side when the lid body 7 is closed), and is substantially the same height as a hinge portion (not shown). Is provided. Here, since the latch part 32 is provided in the substantially symmetrical position on both sides of the center part of the cover body 7 with respect to the part in which the rotating shaft of a hinge part is located, the cover body 7 is more reliable and stable. Therefore, it can be in a closed state.

  Further, as shown in FIG. 5, the latch portion 32 is integrally formed with the closing suppression portion 8 and the hole 26 as the opening / closing adjustment base 21 attached to the lid body 7. A portion of the surface of the opening / closing adjustment base 21 excluding the latch portion 32 and the opening / closing suppression portion 8 is covered with a lid backing plate 24 formed of stainless steel or the like, and an inner edge portion of the lid body 7 is covered with a screw or the like. It is attached (see FIG. 2).

  Next, with reference to FIGS. 5 to 7, the details of the configuration of the closing suppression portion 8 that is provided on a part of the facing surface between the edge portion of the lid body 7 and the opening portion 6 and is raised when the washing machine is not used. explain. The closing suppression portion 8 is fastened to the engagement hole provided on one end side of the opening / closing adjustment base 21 with a screw 23 with a spring 22 interposed therebetween. Furthermore, on the outer peripheral side of the engagement hole, a spiral groove 28 is carved in the direction of the opening, and the convex portion 8a of the closing suppression portion 8 rotates and slides with respect to the spiral groove 28. The closing suppression unit 8 floats in the direction of the opening. Then, by fitting the convex portion 8a of the closing suppression portion 8 into the concave shape 21a of the opening / closing adjustment base 21 shown in FIG.

  Thus, by fixing the closing suppression portion 8, it is possible to prevent the lid body 7 from being held in the closed state by the locking means 15. The spring 22 sandwiched between the closing suppression portion 8 and the opening / closing adjustment base 21 is in an open state (FIG. 6A) at the initial stage, whereas the closing suppression member 8 is in a closed state (when fixed). Shrink in the axial direction (see FIG. 6B). In addition, the opening / closing adjustment base 21 including the closing suppression portion 8 and the latch portion 32 is formed using POM (polyacetal) resin, and thus is resistant to sliding.

  (A)-(d) of FIG. 7 has shown the flow of the opening / closing operation | movement of the closing suppression part 8. FIG. (A) is an initial state, and the lid body 7 can be closed in the state (a). (D) has shown the closing suppression state, and the lid 7 is not closed by the locking means 15 in the (d) state. The rotation angle at this time is 140 ° in consideration of operability and operation force. Moreover, (b) and (c) show the state in which the closing suppression unit 8 is rotated and rotated by 45 ° and 90 °, respectively, but when the closing suppression unit 8 is opened in the (b) and (c) states, By returning to the state (a) by the elastic force of the provided spring 22, the member is prevented from being misused.

  In addition, when releasing the fixation of the closing suppression portion 8, a force sufficient for the convex portion 8 a of the closing suppression member 8 to overcome the concave shape 21 a of the receiving portion is applied to either the right or left rotation direction. The elastic force of the spring 22 acts in the axial direction (opening direction) of the closing suppression unit 8 and returns to the initial position (FIG. 7A).

  Further, an engagement groove 27 is provided on the head surface of the closing suppression portion 8, and the closing suppression portion 8 is lifted by rotating using the engagement groove 27. Only when a tool such as a coin is engaged with the engagement groove 27, the head of the closing suppression portion 8 rotates, so that the risk of being trapped in a state where the child misuses and enters the drum can be reduced. . Further, since the engagement groove 27 is set to be in a substantially vertical direction in the initial state of (a), that is, when the washing machine is used, the engagement groove 27 is operated from the front or the back with respect to the closing suppression portion 8. Even if the operator is right or left-handed, there is an advantage that it is easy to operate.

  Further, since the head surface of the closing suppression portion 8 has a concave curved surface that becomes lower toward the engagement groove 27, the coin or the like abuts at a position slightly shifted from the engagement groove 27. Even in this case, it can be guided to the engaging groove 27 along the concave curved surface, and the operability of the closing suppression portion 8 is improved.

  According to the present invention described above, due to the force acting in the closing direction due to the spring force of the hinge portion and the closing suppression action by the closing suppression portion 8, the lid body 7 is not in a fully open state with a simple structure, The lid 7 can be stabilized in a slightly opened state. In the case of a drum-type washing machine, the lid 7 rotates in a substantially horizontal direction around the axis of the hinge portion. However, when the configuration of the present invention is adopted, the lid 7 is completely opened and the space around the washing machine It is possible to prevent the occurrence of mold and the like and the confinement of children without restricting. Moreover, in this invention, since the structure which provides the closure suppression part 8 in the cover body 7 side is employ | adopted, compared with the structure which provides the closure suppression part 8 in the main body side, only the change from a conventional product is easy. In addition, it is easy to attach / remove the closing suppression unit 8 including during maintenance.

  Further, the closing suppression portion 8 of the present invention is integrally formed with the latch portion 32 as the opening / closing adjustment base 21 and is necessarily located in the vicinity of the latch portion 32, so that it is located far from the latch portion 32. Compared with the case where there is the closing suppression portion 8, even if the stroke when the closing suppression portion 8 is lifted is small (for example, 8 mm), it is possible to suppress the accidental closing by closing the lid 7 with a strong force. .
