Referring to FIGS. 1 and 5 to 8, the installation stand 300 is formed to extend upward from a floor 11 of a structure where the wall-mounted drum washing machine 200 is installed. At this time, the installation stand 300 is disposed in contact with the floor 11 and the wall 13, and the wall-mounted drum washing machine 200 is mounted on the installation stand 300.
The installation stand 300 in accordance with the first embodiment of the present invention includes a lower support portion 310 and the upper support portion 320. The lower support portion 310 is placed on the floor 11 so as to be contacted with the floor 11, and the upper support portion 320 is contacted with the wall 13.
The lower support portion 310 includes a pair of bar-shaped frame members 311 and a central member 312. The frame members 311 are disposed to be separated from each other, and the central member 312 connects the frame members 311.
The pair of frame members 311 are installed in contact with the floor 11, and fixed to the floor 11. The pair of frame member 311 may be disposed in parallel to each other. One end of the central member 312 is connected to one frame member 311, and the other end of the central member 312 is connected to the other frame member 311 so as to connect the pair of frame members 311.
The upper support portion 320 is connected to an end of the lower support portion 310, extended upward in parallel to the wall 13, and fixed in a state where the upper support portion 320 is contacted with the wall 13. The wall-mounted drum washing machine 200 is mounted on the upper support portion 320.
Since the lower end of the upper support portion 320 disposed in contact with the wall 13 is connected to the lower support portion 310, the contact state between the upper support portion 320 and the wall 13 may be maintained. That is, since the lower support portion 310 serves as a support of the upper support portion 320, the upper support portion 320 may be supported in a state where the upper support portion 320 is contacted with the wall 13. Thus, although the wall-mounted drum washing machine 200 having a large weight is mounted on the upper support portion 320, the movement of the upper support portion 320 may be blocked. Therefore, the wall-mounted drum washing machine 200 may be reliably fixed on the installation stand 300.
Referring to FIG. 6, the fixing anchors 324 to be coupled to the wall-mounted drum washing machine 200 are formed to protrude from the front surface of the upper support portion 320, which is contacted with the wall-mounted drum washing machine 200.
The ends of the fixing anchors 324 protruding to the front side of the upper support portion 320 are inserted into the through-holes 215 of the rear panel 210. The front ends of the fixing anchors 324, or specifically, the front ends of the fixing anchors 324 positioned at the front side of the rear panel 210 through the through-holes 215 are coupled to the nut members 327. Thus, since the rear panel 210 is prevented from coming off from the fixing anchors 324, the wall-mounted drum washing machine 200 may be reliably mounted on the installation stand 300.
The buffer member 217 is interposed between the rear panel 210 and the upper support portion 320. Thus, the vibrations generated by the rotations of the drum 240 may be blocked from being transmitted to the upper support portion 320.
The upper support portion 320 includes a pair of vertical bars 321 and a plurality of connection bars 322.
The vertical bars 321 have a bar shape extended upward, and are disposed in contact with the wall 13. The bottoms of the vertical bars 321 are connected to the lower support portion 310. The pair of vertical bars 321 are disposed to be separated from each other, and disposed in parallel to each other.
The plurality of connection bars 322 connect the pair of vertical bars 321, and are disposed to be separated from each other along the extension direction of the vertical bars 321.
One ends of the connection bars 322 are coupled to one vertical bar 321, and the other ends of the connection bars 322 are coupled to the other vertical bar 321. Thus, the connection bars 322 support the vertical bars 321 in the side-to-side direction.
The installation stand 300 may be made of wood, metal, or plastic. The installation stand 300 may be fixed to the floor 11 and the wall 13 through an adhesive member, such as structural adhesive, epoxy, silicone, or adhesive tape, in a state where the installation stand 300 is contacted with the floor 11 and the wall 13.
Referring to FIG. 7, an adhesive coupling layer 330 may be additionally formed on the bottom surface of the lower support portion 310, which is contacted with the floor 11, and the rear surface of the upper support portion 320, which is contacted with the wall 13.
Since the adhesive coupling layer 330 has an adhesive surface, the adhesive member may be stably attached to the adhesive coupling layer 330. Thus, the adhesive member may be attached to the bottom surface and the rear surface of the installation stand 300, and the installation stand 300 may be fixed to the floor 11 and the wall 13 through the adhesive member in a state where the installation stand 300 is contacted with the floor 11 and the wall 13.
The adhesive coupling layer 330 may be formed by applying synthetic resin paint onto the bottom surface of the bottom support portion 310 and the rear surface of the upper support portion 320 or formed by bonding a synthetic resin film.
When the adhesive coupling layer 330 is formed on the installation stand 300, the installation stand 300 may be reliably fixed to the floor 11 and the wall 13 through the adhesive member, regardless of the properties of the material forming the installation stand 300, such as water content and surface roughness. For example, the properties may include the quality of wood, a density difference and the like.
Referring to FIG. 8, a buffer member 340 may be additionally coupled to the rear surface of the upper support portion 320 contacted with the wall 13. The buffer member 340 serves to absorb the vibrations generated from the wall-mounted drum washing machine 200.
When the wall-mounted drum washing machine 200 is operated, the vibrations generated by the rotations of the drum 240 are primarily reduced by the buffer member 217 interposed between the rear panel 210 and the upper support portion 320, and secondarily reduced by the buffer member 340 interposed between the upper support portion 320 and the wall 13.
As the vibrations generated by the operation of the wall-mounted drum washing machine 200 are blocked from being transmitted to the wall 13, noise may be reduced.
A bracket 360 has a cross-section formed in an L-shape or right-angled triangle shape which has a length in the vertical and horizontal directions. As the bracket 360 is additionally coupled to a connection between the lower support portion 310 and the upper support portion 320, the coupling strength between the lower support portion 310 and the upper support portion 320 may be reinforced.
Thus, the upper support portion 320 on which the wall-mounted drum washing machine 200 is mounted may be blocked from being separated from the wall 13 and inclined to the front side.

Thus, a user may designate coupling grooves 325 to which the ring portions 326a of the tray 326 are coupled, and may install the tray 326 at a desired position over the upper support panel 323.
Furthermore, since a plurality of trays 326 may be simultaneously stalled over the upper support panel 323, the amount of laundry or detergent housed in the tray 326 may be increased.
FIG. 15 is a perspective view of a wall-mounted drum washing apparatus in accordance with a fourth embodiment of the present invention. FIG. 16 is an exploded perspective view of main parts of the wall-mounted drum washing apparatus in accordance with the fourth embodiment of the present invention. FIG. 17 is a conceptual view for explaining an example of an installation state of the wall-mounted drum washing apparatus in accordance with the fourth embodiment of the present invention. FIG. 18 is a conceptual view for explaining another example of an installation state of the wall-mounted drum washing apparatus in accordance with the fourth embodiment of the present invention.
The installation stand 300 of FIGS. 15 to 18 in accordance with the fourth embodiment of the present invention includes an angle control unit 350 for controlling an angle between a lower support portion 310 and an upper support portion 320 according to the gradient of a floor 11, unlike the first and second embodiments of the present invention.
The angle control unit 350 includes a hinge pin 353 and a fixing member 354.
The upper support portion 320 has an upper protrusion 328 formed at the bottom thereof. The upper protrusion 328 has an upper through-hole 329 through which the hinge pin 353 passes.
The upper protrusion 328 is contacted with a lower protrusion 318 of the lower support portion 310 at a surface where the upper through-hole 329 is formed.
The lower support portion 310 has the lower protrusion 318 formed at an end thereof. The lower protrusion 318 has a lower through-hole 319 through which the hinge pin 353 passes. The lower protrusion 318 is contacted with the upper protrusion 328 at a surface where the lower through-hole 319 is formed.
When the upper protrusion 328 and the lower protrusion 318 are in contact with each other, the upper through-hole 329 and the lower through-hole 319 are disposed to overlap each other. Thus, when the hinge pin 353 is sequentially passed through the upper through-hole 329 and the lower through-hole 319, the upper protrusion 328 and the lower protrusion 318 are coupled through the hinge pin 353.
An end of the hinge pin 353, or specifically, an end of the hinge pin 353 which passes through the upper through-hole 329 and the lower through-hole 319 is coupled to a fixing member 354. Thus, since the hinge pin 353 may be blocked from coming off from the upper through-hole 329 or the lower through-hole 319, the coupling between the upper support portion 320 and the lower support portion 310 may be maintained.
When a bolt member is applied as the hinge pin 353, a nut member may be used as the fixing member 354 to closely attach the hinge pin 353 to the upper support portion 320 and the lower support portion 310.
A floor 11 of a bathroom, a utility room, a veranda or the like where water is used may be formed to be inclined downward to a drain hole. Thus, the floor 11 has a different gradient depending on places.
When the angle control unit 350 is provided as illustrated in FIGS. 17 and 18, the angle between the lower support portion 310 and the upper support portion 320 may be controlled in various manners according to the gradient of the floor 11.
That is, when the fixing member 354 is coupled to the hinge pin 353 after the angle between the lower support portion 310 and the upper support portion 320 is controlled in a state where the fixing member 354 is separated from the hinge pin 353, the lower support portion 310 and the upper support portion 320 may maintain a predetermined angle.
Since the angle between the lower support portion 310 and the upper support portion 320 may be immediately controlled according to the gradient of the floor 11 on which the installation stand 300 is to be installed, the lower support portion 310 may be closely attached to the floor 11, and the upper support portion 320 may be closely attached to the wall 13.
Thus, it is possible to prevent the lower support portion 310 from being separated from the floor 11 in a state in where the upper support portion 320 is fixed to the wall 13. Furthermore, it is possible to prevent the upper support portion 320 from being separated from the wall 13 so as not to be supported by the wall 13 in a state where the lower support portion 310 is closely attached to the floor 11.
In accordance with the embodiments of the present invention, since the wall-mounted drum washing machine is mounted on the installation stand and the installation stand is disposed in contact with the floor and the wall, the wall-mounted drum washing machine may be reliably fixed on the installation stand.
Furthermore, as the installation stand includes the adhesive coupling layer, the installation stand may be fixed in a state in which the installation stand is contacted with the floor and the wall through the adhesive member attached to the adhesive coupling layer.
Furthermore, as the buffer member is interposed between the upper support portion and the wall, the vibrations generated by the operation of the wall-mounted drum washing machine may be suppressed from being transmitted to the wall. Thus, noise may be reduced.
Furthermore, as the installation stand includes the angle control unit, the angle between the lower support portion and the upper support portion may be controlled according to the gradient of the floor on which the installation is to be installed. Therefore, the lower support portion and the upper support portion may be closely attached to the floor and the wall.
The embodiments of the present invention have been disclosed above for illustrative purposes. Those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
