Description

  The present invention relates to a dew condensation removing tool for sucking out water droplets adhering to a ceiling of a bathroom or dew adhering to an inner surface of a window glass of a living room or wiping off dirt.

  Conventionally, water droplets generated on the ceiling due to the combined action of the humidity in the bathroom and the temperature difference between the walls (hereinafter referred to as dew condensation) and the dew condensation generated on the inner surface of the window glass due to the temperature difference between the interior and exterior surfaces of the room window glass are Not only does it cause black mold, it can damage the beauty, but it can also cause allergies and harm health. For this reason, the thing of patent document 1 is provided as a dew removal tool which removes dew condensation, for example.

  In this dew removal tool, a support having a spatula portion and a through hole with a protruding edge portion attached to only one side edge surface and an inclined front edge is attached to the front end of a hollow gripping portion that matches and communicates with the through hole. It is mounted perpendicularly and a storage part is provided at the rear end of the hollow grip part.

  According to the dew removing device having the above-described configuration, the front end of the spatula portion is pressed against the dew condensation removal target surface such as the lower surface of the ceiling of the bathroom or the inner surface of the window glass, and in this state, the dew removal device is pressed against the dew condensation removal target surface.

  The dew removal tool described in Patent Document 1 is a dew removal work in a state in which the pressing strength of the front edge of the spatula portion is kept at a predetermined value or more against the surface to be dew-condensed, particularly the ceiling surface or the upper wall surface of the bathroom. Must be done. However, it is hard work for housewives and the like to continue the dew removal work while pressing the dew removal tool against the ceiling surface in an upward posture, which is practically impossible for the elderly and the like. In addition, since the pressing strength of the ceiling surface of the dew removal tool varies, if the front edge of the spatula part moves away from the dew condensation removal target surface, there is no effect of scraping off the dew condensation by the front edge of the spatula part, and the dew condensation is removed from the dew removal target surface. Will remain. Therefore, since it is required to perform the operation of removing condensation again on the region where the condensation remains, there is a problem that the efficiency of the condensation removal work is lowered.

  Therefore, it is also conceivable to divert the window cleaning tool described in Patent Document 2 to a dew removing tool. Even if the pressing force of the roll against the surface where condensation is to be removed fluctuates somewhat, the sponge roll comes into contact with the ceiling surface or wall surface even if there is a difference in strength. As a result, it is possible to remove the residual wiping of the condensation, and it is possible to efficiently perform the condensation removal operation as compared with the defroster described in Patent Document 1.

  However, since the roll of the cleaning tool for windows is made of sponge, it has a water absorption characteristic, but has a drawback that the water absorption speed is slow and condensation is dropped from the ceiling surface. In addition, since the surface of the sponge is rough, dew condensation remains on the surface where condensation is to be removed, and dirt on the wall surface cannot be wiped off, which may cause mold growth on the wall surface.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a dew condensation removing tool capable of accurately performing dew condensation removal with high work efficiency.

In order to achieve the above object, a dew condensation removing tool according to the present invention includes a dew condensation removing roll that rolls on a surface to be dew removed, a support shaft that rotatably supports the dew condensation removing roll at a roll shaft portion at the tip, A dew removal tool provided with a grip handle to which the base end portion of the support shaft is fixed,
The dew condensation removing roll includes a first water absorbing layer having a small radial dimension constituted by microfibers, and a second water absorbing layer having a radial dimension constituted by a porous member and larger than the first water absorbing layer. The first water-absorbing layer is wound around the outer periphery of the second water-absorbing layer so that the first water-absorbing layer can rotate simultaneously. The first water-absorbing layer has a thick and cylindrical inner layer, and a thin and cylindrical outer layer on the outer peripheral portion of the inner layer. It is characterized by having a two-layer structure .

According to the dew condensation removal tool having the above-described configuration, the dew removal removal object surface is moved by holding the grip handle, pressing the dew condensation removal roll against the dew condensation removal target surface, and moving the dew condensation removal tool along the dew condensation removal target surface. Condensation can be removed by absorbing water with a condensation removal roll.
Condensation is quickly absorbed by the first water-absorbing layer made of microfibers having excellent water-absorbing ability and water-retaining ability, and is removed by the first action that is retained in the first water-absorbing layer. When the water retention of the first water absorption layer is close to the saturation point by continuing the first action, the water retained in the first water absorption layer is absorbed by the second water absorption layer made of a porous member such as a sponge. And the 2nd effect | action which retains water is started, and the saturation point arrival of a 1st water absorption layer is delayed. Thereby, the removal time of the dew condensation due to the first action is extended. The first action following the second action is continued until the water retention of the second water absorption layer reaches the saturation point to remove condensation. The removal of condensation after the water retention of the second water absorption layer reaches the saturation point can be executed until the water retention of the first water absorption layer reaches the saturation point.

  The dew condensation removing roll includes an inner peripheral second water absorbing layer made of a porous member such as a sponge, and an outer peripheral first water absorbing layer made of microfiber wound around the second water absorbing layer. Thus, an economically advantageous structure is obtained in which the thickness of the expensive first water absorbing layer is limited. In addition, since the scraping by the front edge of the spatula portion as in the prior art is not required, even if the pressing strength of the first water absorption layer against the condensation removal target surface varies somewhat, it has excellent water absorption capability and water retention capability. With the first water-absorbing layer, condensation can be removed accurately with high work efficiency. In addition, by taking into account the water absorption action and water retention action of the second water absorption layer, the excellent water absorption ability and water retention ability of the first water absorption layer correspond to the time when the water retention of the second water absorption layer becomes the saturation point. Can be extended. For this reason, frequent “throttle operation” of the first and second water absorption layers during the execution of the condensation removal work is not necessary, and it is possible to accurately remove the condensation with high work efficiency.

In the dew condensation removing tool according to the present invention, the first water absorption layer has a two-layer structure of an inner layer on the second water absorption layer side and an outer layer disposed on the outer periphery of the inner layer . According to this, in cooperation with the outer layer and the inner layer, excellent water absorption capability and water retention capability can be exhibited. However, when the expensive first water absorption layer deteriorates over time or is damaged, the first layer can be replaced by replacing only the outer layer. Since the functional recovery of one water absorbing layer is possible, it is economically advantageous.

In the dew removing device of the present invention, the front end portion of the outer layer is closed by a blocking wall to form a bag shape, and the rear end portion is squeezed so that only the outer layer can be easily replaced in the event of deterioration over time or damage. be able to. Then, by engaging the locking protrusion formed on the rear end of the roll shaft into the slit formed on the condensation removal roll, the rotation of the condensation removal roll is stopped. Can be easily wiped off.
Further, the grip handle has a hollow structure, and a water tray that communicates with the hollow portion of the handle handle is detachably attached to the tip of the grip handle, so that both the first and second water absorption layers reach the saturation point. after, be further dropped water droplets from condensation removal roll by the condensation removal operation is Ru is continued, since the water droplets collected in the water receiving tray may be drained through the hollow portion of the grip handle, the condensation removing work People are prevented from getting wet.

Furthermore, the gripping handle, since its length is increased, it is possible to easily remove the condensation, such as skylight high ceilings and high places.

  The length of the grip handle may be adjustable steplessly by an expansion / contraction means. According to this, regardless of the height of the ceiling, skylight, etc., the length of the handle can be adjusted to an arbitrary length convenient for the operator, and condensation can be easily removed.

  The dew condensation removing tool according to the present invention can realize an economically advantageous configuration in which the thickness of the expensive first water absorption layer is limited. In addition, even if the pressing strength of the first water absorption layer against the condensation removal target surface varies somewhat, the first water absorption layer having excellent water absorption capability and water retention capability can accurately perform the removal of condensation with high work efficiency. In addition, the water absorption function and the water retention function of the second water absorption layer are taken into consideration, so that the excellent water absorption capacity and the water retention capacity of the first water absorption layer correspond to the time when the water retention of the second water absorption layer becomes the saturation point. Therefore, frequent “throttle operation” of the first and second water-absorbing layers during the execution of the condensation removal work is not necessary, and it is possible to accurately remove the condensation with high work efficiency.

Hereinafter, preferred embodiments of a dew condensation removing tool according to the present invention will be described with reference to the drawings.
FIG. 1 is a front view showing a partial section of an embodiment of a dew removing device according to the present invention, FIG. 2 is a right side view of FIG. 1, and FIG.

  1 to 3, a dew condensation removing tool 1 includes a dew condensation removal roll 2, a support shaft 3 made of a metal rod that rotatably supports the dew condensation removal roll 2 by a roll shaft portion 3 a on the front end side, and a support shaft 3. And a cylindrical grip handle 4 made of a resin molded body in which the base end portion 3b is fitted and fixed. In addition, since the present Example does not have the support shaft 3 on both sides of the condensation removal roll 2 as in Patent Document 2, when wiping the corner of the ceiling, the front end portion of the condensation removal roll 2 (FIGS. 1 and 3). Can be wiped up to the smear.

  The dew condensation removing roll 2 is constituted by a cylindrical first water absorption layer 20 having a small radial dimension constituted by microfibers and a sponge (porous member), and a front end portion (left end portion in FIGS. 1 and 3). ) Is closed by the blocking wall 21 a and has a cylindrical second water absorbing layer 21 whose radial dimension is larger than that of the first water absorbing layer 20, and the first water absorbing layer 20 can rotate simultaneously on the outer periphery of the second water absorbing layer 21. The first water-absorbing layer 20 has a two-layer structure including a thick, cylindrical inner layer 22 and a thin outer layer 23 disposed on the outer periphery of the inner layer 22 so as to be rotatable simultaneously. . The front end portion (left end portion in FIGS. 1 and 3) of the outer layer 23 is closed by a blocking wall 23a to form a bag shape, and the rear end portion (right end portion in FIGS. 1 and 3) is a rubber band. It is narrowed down by 23b.

  As shown in FIG. 3, a bearing member 6 is fitted into the inner periphery of the second water absorption layer 21 in the dew condensation removing roll 2, and the center shaft 5 is attached to the front end portion (left side in FIG. 3) in the bearing member 6. A shaft is rotatably supported, and a roll shaft portion 3 a is fitted on the middle shaft 5. An inner bearing member 6a is fitted on the rear end portion (right side in FIG. 3) of the roll shaft portion 3a, and the inner bearing member 6a is also rotatably supported with respect to the roll shaft portion 3a. A locking projection 31 is formed at the rear end of the roll shaft portion 3a, and a slit 32 is formed in the dew condensation removing roll 2 (the bearing member 6 and the inner bearing member 6a) to engage the locking projection 31. By pushing the roll shaft portion 3a into the dew condensation removing roll 2, the locking projection 31 is fitted into the slit 32, the rotation of the dew condensation removing roll 2 is stopped, and the first water absorption layer 20 is attached to the dew condensation removal target surface. Can be wiped off.

  The grip handle 4 is provided with a plurality of water tray mounting pieces 4a projecting upward at the upper end of the grip handle 4 so that a water tray to be described later can be attached and detached and communicated with the hollow portion 4b. It is done. Further, a female screw 4c communicating with the hollow portion 4b is provided at the lower end portion of the grip handle 4. However, in the present invention, the water tray mounting piece 4a, the hollow portion 4b, the female screw 4c, and the water tray are not necessarily required, and the grip handle 4 may be a handle made of a solid resin.

The dew condensation removing tool 1 having the above-described configuration holds the grip handle 4 and pushes the first water absorption layer 20 in the dew condensation removal roll 2 against the dew condensation removal target surface 60 such as the ceiling of the bathroom shown in FIG. hit, the condensation removal device 1 along the condensation removal target surface 60 by moving the arrow f1, f2 direction, be removed by water dew condensation removal target surface 60 (not shown) in the condensation removal rolls 2 it can.

  The microfibers constituting the first water-absorbing layer 20 are made of an ultrafine polyamide resin fiber or polyester resin fiber of 8 μm or less, and the cross-sectional shape of each micro-unit fiber has a radial triangular cross section, so numerous gaps These innumerable gaps have a characteristic of taking in a large amount of water by capillary action and holding (holding) the taken-in water. That is, the 1st water absorption layer 20 comprised with the microfiber has the outstanding water absorption capability and water retention capability.

  Condensation can be easily removed by the first action of water absorption by the first water absorption layer 20 made of microfibers having excellent water absorption capability and water retention capability, and water retention in the first water absorption layer 20. When the water retention of the first water absorption layer 20 is close to the saturation point by continuing the first action, the water retained in the first water absorption layer 20 is absorbed by the second water absorption layer 21 made of sponge, And the 2nd effect | action which retains water is started, and the saturation point arrival of the 1st water absorption layer 20 is delayed. Specifically, when the water retention of the thin outer layer 23 in the first water absorption layer 20 reaches the saturation point, and subsequently the water retention of the thick inner layer 22 in the first water absorption layer 20 approaches the saturation point, the water is retained in the thick inner layer 22. The second action of absorbing and retaining water by the second water absorption layer 21 is started, and the saturation point of the first water absorption layer 20 is delayed. Thereby, the removal time of the dew condensation due to the first action is extended. The first action following the second action is continued until the water retention of the second water absorption layer 21 reaches the saturation point to remove condensation. The removal of condensation after the water retention of the second water absorption layer 21 reaches the saturation point can be performed until the water retention of the first water absorption layer 20 reaches the saturation point.

The dew condensation removing roll 2 includes an inner peripheral second water absorbing layer 21 made of sponge and an outer peripheral first water absorbing layer 20 made of microfiber wound around the second water absorbing layer 21. Thus, an economically advantageous structure in which the layer thickness of the expensive first water absorbing layer 20 is limited thinly can be obtained. In addition, since the scraping by the leading edge of the spatula portion as in the prior art is not required, even if the pressing strength of the first water absorption layer 20 against the condensation removal target surface 60 slightly varies, excellent water absorption capability and water retention capability With the first water absorption layer 20 having the above, it is possible to accurately remove condensation with high work efficiency. In addition, by taking into account the water absorption action and water retention action of the second water absorption layer 21, the excellent water absorption ability and water retention ability of the first water absorption layer 20 can be achieved at the time when the water retention of the second water absorption layer 21 becomes the saturation point. It can be extended correspondingly. For this reason, frequent “throttle operation” of the first and second water absorption layers 20 and 21 during the execution of the condensation removal work is not necessary, and it is possible to accurately remove condensation with high work efficiency. Become.

  The first water-absorbing layer 20 has a two-layer structure of a thick inner layer 22 on the second water-absorbing layer 21 side and a thin outer layer 23 disposed on the outer periphery of the inner layer 22, so that the cooperation between the outer layer 23 and the inner layer 22 is achieved. The function of the first water-absorbing layer 20 can be restored by replacing only the thin outer layer 23 when the expensive first water-absorbing layer 20 is deteriorated or damaged over time, although it can exhibit excellent water-absorbing ability and water-retaining ability. Is economically advantageous.

  If the water retention of the first water absorption layer 20 and the second water absorption layer 21 reaches the saturation point, the condensation removal roll 2 may be removed and squeezed by hand. The microfiber constituting the first water absorption layer 20 has the above-described excellent water absorption capability and water retention capability, and also has excellent drainage capability, so even with a large amount of moisture retained up to the saturation point, It can be easily drained by a squeezing operation. Further, the deformation of the dew condensation roll 2 that occurs during the squeezing operation disappears almost instantaneously due to the elasticity of the second water absorption layer 21 made of sponge when the squeezing operation is released, and the dew condensation removal roll 2 can be restored to its original shape. .

As shown in FIG. 5, a resin water tray 7 communicating with the hollow portion 4 b of the grip handle 4 is attached and detached using a plurality of water tray mounting pieces 4 a protruding from the tip of the grip handle 4. It may be attached as possible. When the water tray 7 is attached, during the condensation removal operation, the pressing strength of the condensation removal roll 2 against the condensation removal target surface 60 becomes excessive, or both the first and second water absorption layers 20 and 21 are saturated. After reaching the point, even if the condensation removal operation is continued, even if water droplets drip from the condensation removal roll 2, the water droplets are collected by the water tray 7 and drained through the hollow portion 4 b of the grip handle 4. Therefore, it is possible to prevent the condensation removal operator from getting wet. If one end portion of the coupling 8 is screwed to the female screw 4c at the lower end portion of the gripping handle 4 and the tip end portion of the flexible tube (resin hose) 9 is connected to the other end portion of the coupling 8, it is dropped. It is possible to drain the dropped water droplets to a specific drainage location in a state in which wetting of the condensation removal worker by the water droplets is reliably prevented.

Instead of the flexible tube (resin hose) 9 described in FIG. 5, a male screw 10a at the upper end of the long auxiliary handle 10 is screwed onto the female screw 4c at the lower end of the gripping handle 4 as shown in FIG. Thus, if the overall length of the grip handle 4 is increased correspondingly to the length of the auxiliary handle 10, the condensation can be easily removed even if the condensation removal target surface 60 is a high ceiling, a high skylight or the like. .

Furthermore, as shown in FIG. 7, the length of the grip handle 4 can be adjusted steplessly by the expansion / contraction means 11. The expansion / contraction means 11 includes an inner cylinder 12, an outer cylinder 13, and an expansion / contraction lock nut 14. The expansion / contraction means 11 has an inner / outer double structure in which the inner cylinder 12 is inserted into the outer cylinder 13 so as to be slidable in the axial direction. The male screw 12a at the upper end of the inner cylinder 12 is screwed to the female screw 4c of the inner portion to be coupled to the grip handle 4. In addition, the tightening operation of the telescopic lock nut 14 prevents the relative movement of the outer cylinder 13 and the inner cylinder 12 to hold the entire length of the grip handle 4 at a predetermined length, and the loosening operation of the telescopic lock nut 14 The cylinder 13 and the inner cylinder 12 can be moved relative to each other so that the entire length of the grip handle 4 can be expanded and contracted. Thus, if the overall length of the gripping handle 4 is adjustable steplessly, the length of the gripping handle 4 can be adjusted to the convenience of the operator regardless of the height of the dew condensation removal target surface 60 such as the ceiling or skylight. It can be adjusted to any good length to easily remove condensation.

  5, 6, and 7, the same parts as those in FIGS. 1 to 4 are denoted by the same reference numerals, and the description of the overlapping structure and operation is omitted.

  Use as a dew removal tool to remove water droplets adhering to the ceiling due to the combined action of the humidity and temperature difference in the bathroom, or to remove condensation adhering to the inner surface of the window glass due to the temperature difference between the interior and exterior window glass in winter. .
