  • a baffle and optionally a seal are arranged at the accommodating portion of the rotary wheel housing D12 for the rotary wheel driving mechanism D13, so as to prevent the airflow from flowing to the accommodating portion for the rotary wheel driving mechanism D13 from the accommodating portion for the moisture-absorbing rotary wheel assembly D11, thereby protecting the rotary wheel driving mechanism D13 against moisture.

  • the peripheral roller support D1222 is arranged on an end surface of the stair that extends in a direction perpendicular to the axis of rotation, namely, in the axial direction.
  • the peripheral roller D1221 is rotatably supported on the peripheral roller support D1222.

  • the rotary wheel housing seal D124 may also be a structure formed independently and mounted on the inner wall of the rotary wheel housing D12, or a structure integrally formed on the inner wall of the rotary wheel housing D12. Certainly, the following is also conceivable.
  • the peripheral roller D1221 protrudes from an inner peripheral wall of the rotary wheel housing D12 only in its axial direction, and may not be a structure that protrudes from the inner periphery of the rotary wheel housing D12 most, provided that the moisture-absorbing rotary wheel assembly D11 can be in rolling contact with the peripheral roller D1221 at least part of time during the rotation process.
  • the rotary wheel seal D116 is formed from an outer surface of an outer periphery of the moisture-absorbing rotary wheel assembly D11 per se or from a surface structure integrally constructed on the outer surface; and/or the rotary wheel housing seal D124 is formed from an inner surface of the rotary wheel housing D12 per se or from a surface structure integrally constructed on the inner surface.

  • the rotary wheel seal D116 is formed from the outer peripheral surface of the moisture-absorbing rotary wheel assembly D11 per se; and the rotary wheel housing seal D124 is formed from a sealing wool top fixed on the inner peripheral surface of the rotary wheel housing D12.

  • the rotary wheel seal D116 and the rotary wheel housing seal D124 are arranged on the same plane side by side in a direction perpendicular to the axis of rotation, so that the rotary wheel seal D116 and the rotary wheel housing seal D124 form contact sealing in a relatively rotatable manner by using their opposite peripheral surfaces.
  • the rotary wheel seal D116 and the rotary wheel housing seal D124 are arranged in a staggered manner but adjacent to each other along the axis of rotation, so that the rotary wheel seal D116 and the rotary wheel housing seal D124 form contact sealing in a relatively rotatable manner by using their opposite end surfaces.
  • the rotary wheel driving mechanism D13 arranged at the outer periphery of the moisture-absorbing rotary wheel assembly D11 can very flexibly utilize circumferential space of the moisture-absorbing rotary wheel assembly D12, so as to reduce an axial size of the moisture-absorbing and moisture-removing component D1. Therefore, the moisture-absorbing and moisture-removing component is entirely flatter. This can make a contribution to reducing an entire height or thickness of a tableware treating apparatus.
  • Arrangement of the outer peripheral housing part D112 can also avoid deformation of the wheel disk D111 caused by a centrifugal force in the rotation process of the wheel disk D111, particularly deformation of the wheel disk D111 after moisture absorption in the peripheral region, and can avoid direct collision of the wheel disk D111 with the rotary wheel housing D12 caused by reasons such as vibration, thereby avoiding damage.
  • the outer peripheral housing part D112 per se can also reduce a radial spacing between the moisture-absorbing rotary wheel assembly D11 and the rotary wheel housing D12, thereby reducing an amount of airflow that does not flow through the moisture-absorbing rotary wheel assembly. Therefore, the moisture-absorbing efficiency is improved.
  • the end segment of the outer peripheral lower clamping housing D112L is constructed to at least partially cover a mounting position of the bottom roller mechanism D123 on the lower rotary wheel housing D12L, so that the end segment of the outer peripheral lower clamping housing D112L can be in rolling contact with the bottom roller mechanism D123.
  • Both the central upper clamp D113U and the central lower clamp D113L penetrate through a center hole of the wheel disk D111 and are mutually clamped by using a buckle and a clamping slot constructed thereon, so that a groove having only one open side and used for accommodating a central region of the wheel disk D111 is formed in an outer side of the central housing part.
  • the following is also conceivable: only the central upper clamp D113U or only the central lower clamp D113L penetrates through the center hole of the wheel disk D111.
  • the power input part D114 is provided on an outer peripheral surface of the outer peripheral upper clamping housing D112U.
  • the power input part D114 may be integrally formed with the outer peripheral upper clamping housing D112U, and may be manufactured separately and then fixed, for example, welded, onto the outer peripheral surface of the outer peripheral upper clamping housing D112U.
  • the power input part D114 is constructed as straight teeth that are uniformly distributed in a circumferential direction.
  • the rotary wheel driving mechanism D13 has an output gear that can be mutually meshed with the power input part D114, as shown in FIG. 8 .
  • the power input part D114 may also be provided on an outer peripheral surface of the outer peripheral lower clamping housing D112L.
  • the power input part D114 and the rotary wheel driving mechanism D13 are constructed to be in another gear meshed transmission form (for example, a worm and gear transmission form, a bevel gear transmission form, or the like), or a belt transmission form (for example, a friction belt transmission form, a meshing belt transmission form, or the like), or a chain transmission form.
  • the power input part D114 may also be constructed as a helical gear or spiral gear used in a gear transmission form, a smooth surface used in the friction belt transmission form, various shapes of grooves used in the meshing belt transmission form, sprocket teeth used in chain transmission, or the like.
  • the power input part D114, the auxiliary rotary ring D115, and the rotary wheel seal D116 are completely staggered along the axis of rotation, and are particularly next to each other.
  • the rotary wheel seal D116 forms a maximum diameter of the moisture-absorbing rotary wheel assembly D11; and the peripheral roller mechanism D122 protrudes from an entire inner peripheral wall at the inner periphery of the rotary wheel housing D12 towards the axis of rotation, so as to be in rolling contact with the auxiliary rotary ring D115 having a smaller diameter.
  • the auxiliary rotary ring D115 forms a maximum diameter of the moisture-absorbing rotary wheel assembly D11.
  • the rotary wheel housing seal D124 fitting the rotary wheel seal and serving as a portion of the inner peripheral surface of the rotary wheel housing D12 is closer to the axis of rotation.
  • the auxiliary rotary ring D115 of the moisture-absorbing rotary wheel assembly D11 needs to be in rolling contact with the peripheral roller mechanism D122 before deformability of the rotary wheel seal D116 is exhausted completely, so as to prevent the rotary wheel seal D116 from getting stuck relative to the rotary wheel housing seal D124.
  • a radial inner side of the rotary wheel seal D116 covers the position where the outer peripheral upper clamping housing D112U and the outer peripheral lower clamping housing D112L are fixed to each other. In this way, the position where the outer peripheral upper clamping housing D112U and the outer peripheral lower clamping housing D112L are fixed to each other can be sealed by the radial inner side of the rotary wheel seal D116, thereby preventing an airflow entered the moisture-absorbing rotary wheel assembly D11 from flowing out through a mounting gap of the outer peripheral housing part.
  • the rotary wheel seal D116 is further constructed to extend outwards all the way in a direction perpendicular to the axis of rotation, namely, the radial direction, till it can get in contact in a relatively rotatable manner with the rotary wheel housing seal D124 on the inner peripheral surface of the rotary wheel housing D12.
  • “Get in contact in a relatively rotatable manner” means that contact between the rotary wheel seal D116 and the rotary wheel housing seal D124 does not obviously increase a rotational resistance of the moisture-absorbing rotary wheel assembly D11 having the rotary wheel seal D116.
  • the rotary wheel housing seal D124 in the embodiment shown in this figure is formed from an inner peripheral surface of the rotary wheel housing D12 per se.
  • the inner peripheral surface of the rotary wheel housing D12 may also be constructed as a protrusion that protrudes inwards slightly in the radial direction, so as to serve as the rotary wheel housing seal D124 in contact sealing with the rotary wheel seal D116. Therefore, a radial size of the rotary wheel seal D116 can be reduced. In this way, the rotatable contact sealing explained above can be achieved even when the outer peripheral surface of the rotary wheel seal D116 is not at the maximum diameter of the entire moisture-absorbing rotary wheel assembly D11.
