Therefore, when the user tries to open the outer lid 50 during the dehydration operation for some reason (addition of an object to be dehydrated or take out halfway), first, the user places a hand on the slide operation portion 61a of the slide member 61, The slide member 61 is slid in the counter arrow C direction to the second predetermined position (Y). As a result, the outer lid 50 is in the unlocked state, and the open / close switch 69 is in the open state, so that the motor 44 is de-energized and the dehydration basket 43 is in the inertial rotation state. Thereafter, since the user opens the outer lid 50, it takes a certain amount of time (approximately 1 second, although there are differences depending on the user), and the operating hand is moved from the rear slide operation unit 61a to the front outer lid. After the outer cover 50 is moved to the outer cover handle 50a, the outer cover 50 is opened, so that the braking force is applied to the brake mechanism 54 and the dehydration basket 43 is rotated.

  The timing at which this brake is applied is a state in which the dewatering basket 43 is in inertial rotation, and it takes time to move the operating hand from the rear slide operation portion 61a to the outer lid handle portion 50a of the front outer lid 50. Therefore, the dehydration basket 43 is braked with the inertial force of inertial rotation reduced to some extent. Thereafter, the user opens the inner lid 58 by placing a hand on the inner lid handle portion 76 of the front inner lid 58a from the outer lid handle portion 50a of the outer lid 50 and pulling it upward. Also at this time, the user moves the operating hand from the outer lid handle 50a of the outer lid 50 moved rearward to the inner lid handle 76 of the front front inner lid 58a (this also varies depending on the user). However, the dewatering basket 43 is in a completely stopped state or at a lower speed than a low predetermined rotational speed that can ensure safety even if it is rotating. is there. Therefore, when the user takes out the object to be dehydrated, his / her hand or finger does not get caught in the rotating dehydration basket 43 or the object to be dehydrated, and a highly safe dehydrator can be realized.

  Further, when the user opens the outer lid 50 by pulling up and pulling the outer lid handle 50a during the dehydrating operation, if the outer lid 50 is not opened more than a predetermined amount, the inner lid handle portion of the front inner lid 58a. Even if it is intended to open the inner lid 58 by placing a hand on 76, the inner lid handle 76 cannot be lifted upward, so that it cannot be opened. Then, after opening the outer lid 50 by a predetermined amount or more, the inner lid 58 is lifted upward by placing a hand on the inner lid handle portion 76 of the front inner lid 58a. At this time, when the outer lid 50 is opened by a predetermined amount or more, the locking of the substantially inverted L-shaped portion 57b of the control wire mounting plate 57a is surely released from the rear projecting portion 52 of the outer lid 50, and the dehydrating basket 43 The rotation can be reliably braked. Therefore, when the user opens the inner lid 58, the dewatering basket 43 is in a completely stopped state or at a lower speed than a low predetermined rotational speed that can ensure safety even if it is rotating.

  Further, a rib 77 is provided on the inner surface side of the outer lid 50 at a position corresponding to the concave portion 75 provided in the front inner lid 58a in a state where the outer lid 50 and the inner lid 58 are closed. Since it is formed so as to be close to the lid handle portion 76 and enter the recess 75, the user opens the outer lid 50 to the extent that a hand or a finger can be inserted, and then puts the hand on the inner lid handle portion 76. However, since the rib 77 is in the way and the hand cannot be put, it is difficult to touch the dewatering basket rotating at high speed. Therefore, in order to open the inner lid 58, the outer lid 50 must be opened more than a predetermined amount. At that time, the rotation of the dehydration basket 43 is caused by the power supply interruption to the motor 44 and the braking force of the brake mechanism 54. Can be kept below a low predetermined rotational speed that can ensure safety.

  Further, a front projecting portion 78 projecting forward is provided at the lower center of the front end of the front inner lid 58a, and the front projecting portion with the inner lid 58 closed in the center of the front end of the opening 47 of the cover body 46 is provided. Since the hole portion 79 into which the 78 enters is provided, even if the inner lid handle portion 76 of the front inner lid 58a is lifted by hand, a phenomenon that only the front end portion of the front inner lid 58a is lifted does not occur. Further, even if the front inner lid 58a is deformed due to thermal deformation, change with time, etc., a phenomenon that only the front end portion is lifted does not occur. Therefore, a hand or a finger does not enter from the front end portion of the front inner lid 58a with the inner lid 58 closed. Therefore, a highly safe dehydrator can be realized without being entangled with the dehydration basket 43 or the object to be dehydrated, in which the hand or finger is rotating.

  Therefore, according to the above-described configuration, the dehydrator of the present invention does not require a driving device or the like for locking the lid, can reliably lock the outer lid 38 by the above-described inexpensive method, and is in the middle of dehydration. Thus, safety can be secured even when the outer lid 38 is opened. Further, when the dewatering basket 43 is rotating at a high speed, the user cannot touch the dewatering basket 43, and the dewatering basket 43 is in a completely stopped state or is low enough to ensure safety even if it is rotating. Since the dehydration basket 43 can be touched only in a state of a predetermined rotational speed or less, reliability and safety can be improved, and cost reduction can be realized.

  In the first embodiment, the lock surface 67a of the lock member 67 and the contact surface 68a of the pressing member 68 are rotated by the slide operation of the slide member 61, but with the slide operation of the slide member 61. Thus, the lock surface 67a of the lock member 67 slides, the lock surface 67a of the lock member 67 enters and stops below the rear protrusion 52 formed on the outer lid 50, and the contact surface 68a of the pressing member 68 slides. The open / close switch 69 may be closed, and it goes without saying that the same effect can be obtained by this configuration.

  Further, instead of the slide operation of the slide member 61, a rotation support portion may be provided between the slide operation portion 61a and the inverted U-shaped portion 61b, and the lock state and the unlock state may be switched by the rotation operation. It goes without saying that the effect of can be obtained.

  Further, portions corresponding to the first arm 65a, the second arm 65b, and the locking pin 66 are directly projected above the panel member 49, and the portions corresponding to the first arm 65a, the second arm 65b, and the locking pin 66 are provided. It goes without saying that the same effect can be obtained by directly operating the switch to switch between the locked state and the unlocked state.

  In addition, the concave portion 75 and the inner lid handle portion 76 are provided in the front inner lid 58a. However, the concave portion 75 and the inner lid handle portion 76 are provided in the rear inner lid 58b, and ribs 77 are provided on the inner surface side of the outer lid 50 corresponding thereto. Needless to say, this structure can provide the same effect.

  Further, the rib 77 is formed so that the lower end portion thereof is close to the inner lid handle portion 76 and enters the recess 75. However, if the outer lid 50 is not opened by a predetermined amount or more, the rib 77 Of course, if the configuration cannot be applied, the rib 77 does not extend until the lower end of the rib 77 enters the recess 75, and it is needless to say that the same effect can be obtained just by bringing it close to the recess 75.

  As described above, the dehydrator according to the present invention reliably locks the lid by an inexpensive method, and the user cannot touch the dehydration basket when the dehydration basket is rotating at high speed, and the dehydration basket is completely Even if it is in a stopped state, or even if it is rotating, it can be touched only at a low speed below a predetermined rotation speed that can ensure safety, and the safety is enhanced, so the outer lid and the inner lid The present invention is useful as a dehydrator having a lid locking mechanism and a washing machine having a dehydrating function and having an outer lid, an inner lid, and a lid locking mechanism.
