  The screw block 48 is fitted with a swing arm 52 made of plastic such as nylon. The swing arm 52 has a substantially flat arm main body 53 whose longitudinal direction extends in parallel with the longitudinal direction of the recess 26 for installing the drive mechanism, and is located at a substantially intermediate portion of the arm main body 53 in the longitudinal direction. A block insertion hole 54 penetrating in the thickness direction is formed. The block insertion hole 54 is formed in a substantially rectangular plane that is long along the longitudinal direction of the swing arm 52, and the upper portion of the screw block 48 is inserted into the block insertion hole 54 from below and fitted. At this time, the lower surfaces on both sides orthogonal to the longitudinal direction of the formation portion of the block insertion hole 54 of the swing arm 52 are in contact with the upper surface of the support portion 49a of the arm support arm 49, and the swing arm 52 is The biasing spring 51 is always biased upward by the spring force. Further, the block insertion hole 54 and the arm support arm 49 function as a detent for preventing the screw block 48 from rotating on the screw shaft 45.

  The base portion located on the back side of the installation space SA of the swing arm 52 is formed in a bifurcated shape so that the back side forms a substantially U-shaped plane of the opening, and stands on the upper surface of the base body 22 in the opening. An upper end portion of the provided mounting base 55 is inserted. The upper end portion of the mounting base 55 and the base of the swing arm 52 are connected by a metal connecting pin 56 that extends horizontally, and the swing arm 52 can swing around the connecting pin 56. Is formed.

  Accordingly, the swing arm 52 is configured to reciprocate in the vertical direction about the connecting pin 56, that is, to be swingable, and is transmitted through the screw block 48. It is always biased upward by force.

  The tip of the swing arm 52 protrudes outside the opening 26 a, and a pedal 57 is integrally formed on the top surface of the tip of the swing arm 52. That is, the pedal 57 is disposed so as to protrude from the opening of the drive mechanism installation recess 26. Further, the pedal 57 is disposed such that its longitudinal direction is along the left-right direction, and the rear end of the pedal 57 is opposed to the front surface of the case 3. The basket 2 is configured to rotate when the user steps on the pedal 57.

  It should be noted that the case 3 and the swing arm 52, and thus the color of the pedal 57 are different colors, for example, the case 3 is yellow and the pedal 57 is blue, so that the visibility of the operation unit by the user, that is, the pedal 57 is conspicuous. Therefore, the operation unit can be easily recognized.

  Next, the operation of the present embodiment having the above-described configuration will be described.

  When using the simple dehydrating apparatus 1 of the present embodiment, the handle 38 of the upper lid 23 is operated upward to bring the upper lid 23 shown in FIG. 2 into an open state. At this time, the upper lid 23 can be easily opened by stepping on the stepping portion 31 formed on the upper surface of the base body 22. Then, by opening the upper lid 23, the opening of the basket 2 is exposed.

  Next, an object to be dehydrated is supplied into the basket 2. Next, the opened upper lid 23 is closed, and the upper lid 23 shown in FIG. 1 is closed. At this time, a plurality of positioning pieces 35 a provided on the steadying body 35 are inserted inside the opening end of the basket 2, the opening of the basket 2 is covered with the steadying body 35, and the opening of the case main body 21 is covered with the top lid 23. Covered by.

  Next, in a state where the stopper 33 disposed on the upper surface of the base body 22 is tilted, the operation of depressing the pedal 57 with one foot, for example, the right foot, is repeated. Here, when the operating force is released after the pedal 57 is pushed down to the lowermost end, the pedal 57 is automatically returned to the original position by the spring force of the biasing spring 51. Therefore, since the user only needs to use force when performing an operation of depressing the pedal 57, the burden of labor can be reduced.

  Further, when the depression operation of the pedal 57 is repeated, the simple dehydrator 1 can be fixed at the use location by stepping on the stepping portion 31 formed on the upper surface of the base body 22 with the other foot, for example, the left foot. The device can be prevented from moving or tilting.

  That is, since the posture of the simple dehydrator 1 can be stabilized, the pedal 57 can be operated smoothly.

  When the depression operation of the pedal 57 is repeated, the swing arm 52 moves up and down around the connecting pin 56. As the swing arm 52 moves up and down, the screw block 48 moves up and down on the screw shaft 45, and the screw shaft 45 rotates in the forward and reverse directions. Of the rotation of the screw shaft 45, only one-way rotation that occurs when the pedal 57 is pushed down is transmitted to the drive shaft 41 via the one-way clutch, the large-diameter gear 44, and the small-diameter gear 43 in this order. Rotate 2 The rotation in the other direction of the screw shaft 45 generated when the pedal 57 is raised is not transmitted to the large-diameter gear 44 due to the idling of the one-way clutch.

  Further, the water of the object to be dehydrated stored in the basket 2 is centrifuged by the rotation of the basket 2. The water centrifuged from the dehydration object passes through the through hole 11 of the basket 2 and is stored in the case body 21. At this time, since the steady rest 35 fitted to the opening of the basket 2 rotates together with the basket 2, it is possible to reliably prevent the rotation shaft of the basket 2 from shaking. Further, the upper lid 23 can reliably prevent the object to be dehydrated and the dehydrated water from jumping out.

  The rotation of the basket 2 is accelerated by increasing the stepping force of the pedal 57, that is, by increasing the moving speed of the screw block 48 downward. When the rotation speed of the basket 2 is increased, the centrifugal force increases, so that the time required for dewatering can be shortened and the dewatering ability can be easily improved.

  As described above, according to the simple dehydrating apparatus 1 of the present embodiment, the opening 26 a of the drive mechanism installation recess 26 for obtaining the installation space SA of the rotation drive mechanism 4 is disposed on the front right side of the bottom of the case body 21. Therefore, a space can be provided on the upper surface of the base body 22 on the side opposite to the position where the pedal 57 is disposed. In this space, a stepping portion 31 and the like for stabilizing the posture of the apparatus can be arranged. As a result, it is possible to smoothly perform the operation of depressing and depressing the pedal 57, so that the user-friendliness can be improved easily and reliably.

  Further, according to the simple dehydrating apparatus 1 of the present embodiment, the base body 22 is provided with a stepping space SB in which the base body 22 can be stepped on from the upstream side in the operation direction at the bottom left corner of the case body 21. The stepping portion 31 that can be stepped on by the user can be easily provided on the front left side of the upper surface of the base body 22 without enlarging the front side and the left side.

  Furthermore, according to the simple dehydrating apparatus 1 of the present embodiment, the pedal 57 is disposed on the front right side and the stepping portion 31 is disposed on the front left side, that is, the position where the pedal 57 and the stepping portion 31 are opposite to each other. Can be improved easily and reliably.

  Furthermore, according to the simple dehydrating apparatus 1 of the present embodiment, the upper lid 23 can reliably prevent the object to be dehydrated and the dehydrated water from jumping out during dehydration.

  Further, according to the simple dewatering device 1 of the present embodiment, the steady rest 35 can reliably prevent the rotation shaft of the basket 2 from shaking, so that the posture of the device during dehydration can be easily and reliably stabilized. be able to.

  Furthermore, according to the simple dehydrating apparatus 1 of the present embodiment, the stopper 33 can be made to be in a depressed state by making it possible to reliably disable the pushing-down operation of the pedal 57, that is, the dehydrating operation, by standing. Since the dehydration operation can be performed by the above, there is a danger caused by an operation different from the user's intention such as rotating the basket 2 with the upper lid 23 opened, or a person other than the user such as a child may use the upper lid 23. Since the danger of rotating the basket 2 in the open state can be avoided, safety can be improved reliably.

  In addition, this invention is not limited to embodiment mentioned above, A various change is possible as needed.
