Description

The present invention relates to a floor unit for a washing machine and a floor structure for connecting a drain hose of a washing machine to a drain pipe disposed below a floor board.

  Conventionally, in order to prevent the dripping of laundry from falling directly on the floor, or to function as a saucer in case the drainage hose of the washing machine comes off, a waterproof pan is installed in advance in the washing machine yard and sanitary of the house, The washing machine was often installed on the waterproof pan so that the legs of the washing machine were inside the waterproof pan.

  On the other hand, flooring materials with excellent water resistance have been developed, and the role of preventing water drops from falling on the floor is no longer necessary. In addition, the possibility that the drainage hose connected to the drainage port of the waterproof pan will come off and the water overflows tends to decrease due to the contrivance of the connection structure, and the drainage hose of the washing machine should be disconnected Considering the capacity of the washing tub, it is difficult in the first place to expect that the waterproof pan will be a sufficient tray.

  In addition, a wide variety of washing machines such as a two-tub washing machine, a drum washing machine, or a fully automatic washing machine have been commercialized to meet the various needs of today, and specifications such as width, depth, or height are Although some measures have been taken for waterproof pans, there are not a few washing machines that limit the size of waterproof pans that can be installed.

  Therefore, recently, there has been an increase in new construction examples and renovation examples in which a waterproof pan is omitted and a drain outlet is directly installed on the sanitary floor, and a drain hose of a washing machine is attached to the drain outlet.

  However, even in the situation where the waterproof pan is omitted, there is no change to the point where the installation position of the drainage port needs to be decided somewhere in the sanitary, so when connecting the washing machine hose to the drainage port installed in advance, Depending on the positional relationship with the bathroom vanity, toilet bowl or filth washing, the drainage port may be exposed and the sanitary aesthetics may be damaged. It was.

  On the other hand, there are rare cases where the specifications and installation position of the washing machine are determined in advance before new construction or renovation work, and there is a concern that even if it has been decided, it will no longer be possible to replace the washing machine. It is extremely difficult to determine in advance where the drain outlet for connecting the hose should be provided in the sanitary or washing machine yard.

The present invention has been made in consideration of the above-described circumstances, and provides a floor unit and a floor structure for a washing machine capable of moving a drain outlet to which a drainage hose of a washing machine is connected to a desired position. Objective.

  In order to achieve the above object, a floor unit for a washing machine according to the present invention has a floor member that can be detachably fitted into an opening formed in a floor board, and penetrates the floor member. The drainage penetrating member that is installed and connected to the drainage hose of the washing machine at the indoor side end, and the upstream end of the drainage pipe that is disposed in the underfloor space that extends below the floorboard is below the floor of the drainage penetrating member A flexible pipe connected to the end, and the floor member and the opening are formed so that a planar shape thereof is rotationally symmetric and non-circular, and the drainage penetrating member is formed on the floor. It is attached at a position eccentric by a predetermined distance from the center of the member.

  The floor unit for a washing machine according to the present invention includes a floor member that is rotatably fitted in an opening formed in the floor board, and a laundry machine that is installed through the floor member and is installed at the indoor side end. The drainage penetrating member to which the machine drainage hose is connected, and the flexibility to connect the upstream end of the drainage pipe disposed in the underfloor space extending below the floorboard to the lower floor end of the drainage penetrating member The floor member and the opening are formed so that the planar shape is circular, and the drainage penetrating member is attached at a position eccentric from the center of the floor member by a predetermined distance. .

The drainage penetrating member is configured to be freely inserted into a slit-like insertion hole formed in the floor member and to be fixed to the floor member at an arbitrary position along the longitudinal direction of the slit-like insertion hole. is there.

The floor unit for a washing machine according to the present invention includes a closing unit that closes a remaining opening of the slit insertion hole in a state where the drainage penetrating member is inserted into the slit insertion hole.
A floor structure for a washing machine according to the present invention is a floor structure for a washing machine including the floor unit for a washing machine according to any one of claims 1 to 4, wherein the drain pipe is disposed upstream of the drain pipe. It is arrange | positioned in the said underfloor space so that the planar position of an edge part may become the center vicinity of the said opening.

  In the floor unit for a washing machine according to the first invention, the floor member and the opening into which the floor member is detachably fitted are formed so that the planar shape has rotational symmetry, so that the floor member is fitted into the opening. Once the floor member is removed and rotated by a predetermined rotation angle from the original fitting position, it can be fitted into the opening of the floor board as in the original fitting state.

  On the other hand, since the drainage penetrating member is attached at a position eccentric from the center of the floor member by a predetermined distance, the drainage penetrating member rotates and moves as the floor member rotates.

  Accordingly, by appropriately changing the fitting angle of the floor member with respect to the opening, the drainage penetrating member is placed at a desired position according to the specifications of the purchased washing machine, for example, a position where the drainage penetrating member does not directly enter the line of sight. Thus, it is possible to prevent a situation in which the drainage penetrating member impairs the aesthetics of the entire sanitary and the degree of purchase freedom of the washing machine is reduced as in the prior art.

  The rotational symmetry refers to a geometric property that overlaps an original figure when a figure is rotated at a certain rotation angle, and corresponds to, for example, a regular polygon. For example, when a square is rotated by 90 °, 180 °, and 270 °, all of them overlap with the original figure. Further, a shape in which four corners of a square are chamfered with the same shape or rounded with the same curvature also has rotational symmetry. Such rotational symmetry includes a circle in terms of geometry, but in the first invention, the circle is excluded, and the floor member and the opening are formed in a non-circular shape.

  The opening provided in the floor board is formed so as not to interfere with the attachment / detachment of the floor member. For example, the opening may be formed with an inner dimension that is substantially the same as or slightly larger than the outer dimension of the floor member.

  As described above, the drainage penetrating member is attached at a position eccentric from the center of the floor member by a predetermined distance. The center here means a rotational axis when having rotational symmetry, for example, many If it is a square, it corresponds to the center. The larger the eccentric distance, that is, the distance from the center of the floor member to the drainage penetrating member, the larger the drainage penetrating member can be moved.

  It is desirable that the floor member is finished with the same finishing material as that of the floor board, and the finished surface is flush with the floor board. For example, the floor member can be configured to be fitted into the opening so as to be placed on a receiving bar attached along the periphery of the opening.

  Although the structure which makes a floor member detachable is arbitrary, for example, while attaching the receiving rail mentioned above to the circumference | surroundings of an opening, it is made to mount on this receiving rail, and the handle employ | adopted as an underfloor storage or an underfloor inspection port is used as a floor member. The structure attached to the surface of this can be considered.

  In the floor unit for a washing machine according to the second invention, the floor member and the opening into which the floor member is rotatably fitted are formed so that the planar shape is circular, so that the floor member fitted into the opening Can be rotated by a desired rotation angle from the original fitting position.

  On the other hand, since the drainage penetrating member is attached at a position eccentric from the center of the floor member by a predetermined distance, the drainage penetrating member rotates and moves as the floor member rotates.

  Accordingly, by appropriately changing the fitting angle of the floor member with respect to the opening, the drainage penetrating member is placed at a desired position according to the specifications of the purchased washing machine, for example, a position where the drainage penetrating member does not directly enter the line of sight. Thus, it is possible to prevent a situation in which the drainage penetrating member impairs the aesthetics of the entire sanitary and the degree of purchase freedom of the washing machine is reduced as in the prior art.

  The opening provided in the floor board is formed so as not to interfere with the rotation of the floor member. For example, the opening may be formed with an inner dimension that is substantially the same as or slightly larger than the outer dimension of the floor member. Unlike the first invention, in the second invention, whether or not the floor member is configured to be detachable with respect to the opening is arbitrary, and it is configured to be rotatable but not removable. Is possible.

  As described above, the drainage penetrating member is attached at a position eccentric from the center of the floor member by a predetermined distance, and the center here refers to a circular center. The larger the eccentric distance, that is, the distance from the center of the floor member to the drainage penetrating member, the larger the drainage penetrating member can be moved.

  It is desirable that the floor member is finished with the same finishing material as that of the floor board so that the finished surface is flush with the floor board. The floor member is placed on a receiving bar attached along the periphery of the opening, for example, and can be configured to be rotatable with respect to the opening by configuring the receiving member to be slidable in this state. .

  In the floor unit for a washing machine according to the third invention, the drainage penetrating member can be inserted into a slit-like insertion hole formed in the floor member at an arbitrary position along the longitudinal direction of the slit-like insertion hole. It is configured to be fixed to the member.

Therefore, by moving the drainage penetrating member along the slit-like insertion hole, the drainage penetrating penetrating hole is placed at a desired position according to the specifications of the purchased washing machine, for example, a position where the drainage penetrating member does not directly enter the line of sight. Thus, it is possible to prevent the situation where the drainage penetrating member impairs the aesthetics of the entire sanitary and the degree of purchase freedom of the washing machine is reduced as in the prior art .

  The opening provided in the floor plate may be formed, for example, with an inner dimension that is substantially the same as the outer dimension of the floor member or a slightly larger inner dimension. Note that, unlike the first invention, in the third invention, it is arbitrary whether or not the floor member is configured to be detachable from the opening.

  It is desirable that the floor member is finished with the same finishing material as that of the floor board so that the finished surface is flush with the floor board. A floor member can be set as the structure mounted, for example on the receiving rail attached along the periphery of opening.

  A means for fixing the drainage penetrating member to the floor member at an arbitrary position along the longitudinal direction of the slit-like insertion hole is arbitrary. For example, the drainage penetrating member is inserted into the slit-like insertion hole in the slit-like insertion hole. The remaining opening of the hole may be closed with a predetermined closing means.

  The drainage penetrating member in the first to third inventions is a drainage port as usual, and for example, a commercially available drainage trap for a washing machine can be diverted. Commercially available products can also be used as the flexible piping. For example, a flexible joint formed by protecting a soft PVC hose with a core coil can be used.
