FIGS. 3 to 10 , the wall-mountedwashing machine 1000 according to one embodiment of the present disclosure may include arear panel 1010 hung on a wall surface, atub 1020 configured to store washing water and supported by therear panel 1010, a drum 1030 rotatably installed inside thetub 1020 and configured to accommodate washing items, adrying device 1040 coupled to an outer surface of thetub 1020 and configured to dry the washing items, adrive unit 1050 configured to supply power for rotating the drum 1030, and ahousing 1060 coupled to therear panel 1010 and configured to form an outer shell of the wall-mountedwashing machine 1000. - The
rear panel 1010 may be hung on the wall surface W. For example, therear panel 1010 may be hung on the wall surface W byseparate fastening members 1011 a. To this end, through-holes 1011 penetrating therear panel 1010 may be formed in therear panel 1010 so that thefastening members 1011 a can be inserted into the through-holes 1011. A method of hanging therear panel 1010 on the wall surface W will now be briefly described. A user first installs thefastening members 1011 a on the wall surface W and fits shock-absorbingmembers 1011 c for the reduction of shock and vibration to thefastening members 1011 a. Thereafter, the user hangs therear panel 1010 on the wall surface W so that thefastening members 1011 a are inserted into the through-holes 1011 of therear panel 1010. Subsequently,nut members 1011 b are coupled to thefastening members 1011 a protruding forward from therear panel 1010 via the through-holes 1011, whereby therear panel 1010 can be hung on the wall surface W. - Additionally, a mounting
groove portion 1012 may be formed on the rear surface of therear panel 1010 so that a space is formed between therear panel 1010 and the wall surface W. The mountinggroove portion 1012 is formed to make sure that the drive unit 1050 (to be described later) can be coupled to therear panel 1010 without interference with the wall surface W. The mountinggroove portion 1012 may be formed by depressing the rear surface of therear panel 1010 at a predetermined depth. - At least one
vent hole 1013 may be formed in therear panel 1010. For example, a plurality ofvent holes 1013 penetrating therear panel 1010 may be formed in the upper portion of therear panel 1010. The vent holes 1013 allow the air existing in the space surrounded by therear panel 1010 and thehousing 1060 to be discharged to the outside, thereby preventing the air existing inside the wall-mountedwashing machine 1000 from being heated. In the drawings, there is shown a configuration in which a plurality ofvent holes 1013 is formed in a rectangular shape in the upper portion of therear panel 1010. However, the present disclosure is not limited thereto. The position and shape of the vent holes may be changed in various ways in order to assure smooth discharge of the air. - In the meantime, a plurality of
ribs 1014 may be provided on the rear surface of therear panel 1010. Theribs 1014 may protrude from the rear surface of therear panel 1010 to enhance the rigidity of therear panel 1010. In this case, the end portions of theribs 1014 may be partially cut away to formair circulation grooves 1014 a. Due to the existence of theair circulation grooves 1014 a, the air passing through the vent holes 1013 may be discharged to the outside. - The
tub 1020 may be provided on the front side of therear panel 1010. In this regard, thetub 1020 may be simultaneously injection-molded with therear panel 1010 and may be integrally formed with therear panel 1010. Alternatively, thetub 1020 may be manufactured as a separate member and, then, may be coupled to therear panel 1010. - A
water supply device 1022 and awater drain device 1023 may be connected to thetub 1020. For example, thewater supply device 1022 may be connected to the upper portion of thetub 1020, and thewater drain device 1023 may be connected to the lower portion of thetub 1020. However, the connection configurations of thewater supply device 1022 and thewater drain device 1023 may be replaced by various connection configurations commonly used in the related art. - The
water supply device 1022 may be connected to an external water supply source. When a user operates anoperation unit 1062 a to carry out a washing operation, thewater supply device 1022 may supply washing water into thetub 1020. The washing water supplied to thetub 1020 may enter the drum 1030 via washingwater introduction holes 1030 a formed on the outer surface of the drum 1030. - When the washing operation is completed, the washing water may be drained to the outside via the
water drain device 1023 installed under thetub 1020. - The drum 1030 may be rotatably coupled to the inside of the
tub 1020. For example, a drivingshaft 1031 may be connected to the drum 1030. The drivingshaft 1031 may be connected to thedrive unit 1050 disposed on the rear surface of therear panel 1010 so that the drivingshaft 1031 can receive power from thedrive unit 1050. - The
drive unit 1050 may be coupled to the rear surface of therear panel 1010 to rotate the drum 1030. In this regard, thedrive unit 1050 may be coupled to the mountinggroove portion 1012 of therear panel 1010. The mountinggroove portion 1012 may be formed to be depressed by a predetermined depth from the rear surface of therear panel 1010. Accordingly, it is possible to prevent interference between thedrive unit 1050 and the wall surface W even when the wall-mountedwashing machine 1000 is installed on the wall surface W. - As an example, the
drive unit 1050 may include amotor 1051 provided with arotating shaft 1051 a and configured to supply power, adriving wheel 1052 connected to the drivingshaft 1031, and abelt 1053 connected to therotating shaft 1051 a and thedriving wheel 1052 to transmit the power of themotor 1051 to thedriving wheel 1052. Thus, when themotor 1051 rotates, therotating shaft 1051 a of themotor 1051 may rotate thebelt 1053, whereby thedriving wheel 1052 may be rotated to rotate the drum 1030. - Washing items may be accommodated inside the drum 1030. One or more washing
water introduction holes 1030 a may be formed on the outer surface of the drum 1030. Thus, the washing water supplied to thetub 1020 may be introduced into the drum 1030 via the washingwater introduction holes 1030 a to wash the washing items. - Reinforcing
ribs 1021 may be provided in the rear portion of thetub 1020 where thetub 1020 and therear panel 1010 make contact with each other. The terms on directions will now be defined. The term “front” may refer to the direction extending from therear panel 1010 toward thetub 1020 on the basis ofFIG. 3 , namely the positive X-axis direction. The term “rear” may refer to the direction extending from thetub 1020 toward therear panel 1010 on the basis ofFIG. 3 , namely the negative X-axis direction. - The reinforcing
ribs 1021 may be formed along the outer circumferential surface of the rear portion of thetub 1020 to protrude radially outward. The reinforcingribs 1021 may include first reinforcingribs 1021 a extending in the circumferential direction of thetub 1020 and second reinforcingribs 1021 b configured to connect the rear surfaces of the first reinforcingribs 1021 a and the front surface of therear panel 1010. In this regard, the second reinforcingribs 1021 b may be formed on the outer circumferential surface of thetub 1020 to be spaced apart from one another in the circumferential direction. Some of the second reinforcingribs 1021 b may be formed to extend toward the front side of thetub 1020. - The reinforcing
ribs 1021 may distribute the stresses that may be concentrated on the portion where thetub 1020 and therear panel 1010 coupled to each other. This makes it possible to prevent damage of thetub 1020 or separation of thetub 1020 from therear panel 1010. - A
tub front panel 1025 may be coupled to the front side of thetub 1020. Thetub front panel 1025 may be coupled to thetub 1020 to form an internal space in which the drum 1030 is disposed. Adetour rib 1027 may be provided in the lower portion of thetub front panel 1025. Thedetour rib 1027 may protrude frontward from the front surface of thetub front panel 1025. The transverse opposite end portions of thedetour rib 1027 may be bent downward so as to make curved surfaces. As used herein, the term “transverse” may refer to the left-right direction when the wall-mountedwashing machine 1000 is viewed from the front side, namely the Y-axis direction on the basis ofFIG. 3 . - A hot water heater
power supply unit 1028 a for supplying electric power to a hot water heater 1028 may be disposed under thedetour rib 1027. Thus, thedetour rib 1027 may prevent the washing water flowing out from the interior of the wall-mountedwashing machine 1000 from making contact with the hot water heaterpower supply unit 1028 a. In addition, anoperation unit 1062 a coupled to the housing 1060 (to be described later) may be disposed under thedetour rib 1027. Thedetour rib 1027 may prevent the washing water from entering theoperation unit 1062 a. - An
opening 1025 a may be formed in thetub front panel 1025. Agasket 1029 for sealing may be coupled to theopening 1025 a of thetub front panel 1025. In this case, the edge portion that forms theopening 1025 a of thetub front panel 1025 may have a step-like shape to increase the coupling strength with thegasket 1029. Thegasket 1029 may seal a gap between thehousing 1060 and thetub 1020 and may prevent foreign materials from entering a space between thetub front panel 1025 and the drum 1030. Thegasket 1029 is fitted to theopening 1025 a of thetub front panel 1025. At least a part of the outer circumferential surface of thegasket 1029 may make selective contact with the door 1063 (to be described later), and the remaining part of the outer circumferential surface of thegasket 1029 may make close contact with theopening 1025 a. For example, thegasket 1029 may have a diameter corresponding to the diameter of theopening 1025 a of thetub front panel 1025. Thegasket 1029 may have a ring shape with the central portion thereof opened and may be made of a rubber material. - A hot air introduction port 1025 b into which a hot air discharged from a hot
air supply duct 1043 of the drying device 1040 (to be described later) is introduced may be formed in the front upper portion of thetub front panel 1025. The hot air introduced through the hot air introduction port 1025 b may move toward the drum 1030 disposed inside thetub 1020. A drying process using the hot air will be described later. - Moreover, the
drying device 1040 for drying the washing items may be provided on the outer surface of thetub 1020. Hereinafter, the detailed configuration of thedrying device 1040 according to one embodiment of the present disclosure will be described with reference toFIGS. 11 to 13 . -
FIG. 11 is a schematic perspective view showing a drying device according to one embodiment of the present disclosure.FIG. 12 is a schematic front view showing the drying device according to one embodiment of the present disclosure.FIG. 13 is a schematic sectional view taken along line XIII-XIII′ inFIG. 11 . - Referring to
FIGS. 11 to 13 , thedrying device 1040 is a device for drying washing items by supplying hot air into thetub 1020. Thedrying device 1040 may be used in conjunction with the front upper portion of thetub front panel 1025 and the rear lower portion of thetub 1020. - For example, the
drying device 1040 may include afan 1041 coupled to the upper portion of thetub 1020 and configured to blow air, a hotair supply duct 1043 connected to thefan 1041 and configured to supply the air into thetub 1020 through the hot air introduction port 1025 b formed in thetub front panel 1025, a dryingheater 1045 provided inside the hotair supply duct 1043 and configured to heat the air introduced into the hotair supply duct 1043, and a hotair discharge duct 1047 connected to thetub 1020 and configured to guide the air passing through thetub 1020 toward thefan 1041. - In the
drying device 1040 provided in the wall-mountedwashing machine 1000 according to one embodiment of the present disclosure, thefan 1041, the hotair supply duct 1043, thetub 1020 and the hotair discharge duct 1047 may form one air circulation path. In other words, thedrying device 1040 may perform a drying process by circulating the air inside the wall-mountedwashing machine 1000. - A condensing
water introduction port 1047 a into which condensing water is introduced may be formed in the hotair discharge duct 1047. Aseparate connector 1047 f may be connected to the condensingwater introduction port 1047 a. A nozzle, a hose and the like for supplying the condensing water may be connected to theconnector 1047 f. - The condensing water (not shown) injected into the hot
air discharge duct 1047 through the condensingwater introduction port 1047 a may be combined with moisture in the air passing through the hotair discharge duct 1047. This makes it possible to remove the moisture existing in the air. Accordingly, the air is cooled and dehumidified while passing through the hotair discharge duct 1047. In this state, the air may be re-introduced into thefan 1041. - In this regard, at least one
curved portion 1047 b may be formed on one surface of the hotair discharge duct 1047 opposite to the condensingwater introduction port 1047 a. Thecurved portion 1047 b may be formed to bulge toward the condensingwater introduction port 1047 a. In the drawings, there is shown onecurved portion 1047 b having a convex shape as a whole. However, the present disclosure is not limited thereto. A plurality ofcurved portions 1047 b may be formed in a wave shape or the like (seeFIG. 10 ). - By forming the
curved portion 1047 b on one surface of the hotair discharge duct 1047 in this way, it is possible to increase the contact area and the contact time of the condensing water with the air passing through the hotair discharge duct 1047. - In other words, the condensing water injected into the hot
air discharge duct 1047 through the condensingwater introduction port 1047 a collides with thecurved portion 1047 b and then flows toward the lower portion of the hotair discharge duct 1047 along thecurved portion 1047 b. This increases the area and the time in which the condensing water flows along the inner surface of the hotair discharge duct 1047, thereby increasing the contact area and the contact time of the condensing water with the air existing in the hotair discharge duct 1047. Consequently, the effect of dehumidifying and cooling the air introduced into thefan 1041 is enhanced and the drying efficiency of thedrying device 1040 is increased. - The condensing
water introduction port 1047 a may be formed such that the area of the longitudinal cross section grows larger from the central portion toward the opposite end portions. For example, the condensingwater introduction port 1047 a may be formed such that the width L2 of the end portion becomes larger than the width L1 of the central portion (seeFIG. 13 ). In addition, the condensingwater introduction port 1047 a may be formed in a polygonal shape with the respective sides of the transverse cross section protruding inward. For example, the transverse cross section of the condensingwater introduction port 1047 a may be formed in a rhombic shape as a whole with the respective sides of a rectangle protruding inward. As used herein, the term “longitudinal” may refer to the Y-axis direction on the basis ofFIG. 3 , namely the left-right direction when the wall-mountedwashing machine 1000 is viewed from the front side, and the term “transverse” may refer to the X-axis direction on the basis ofFIG. 3 , namely the front-rear direction when the wall-mountedwashing machine 1000 is viewed from the front side. - By forming the condensing
water introduction port 1047 a as described above, the surface area of the injected condensing water increases. This makes it possible to increase the contact area between the condensing water and the air flowing through the hotair discharge duct 1047. - A method of drying washing items with the
drying device 1040 will be briefly described. When washing is completed and drying is performed by a user, thefan 1041 is operated. If the air moves along the hotair supply duct 1043 by the operation of thefan 1041, the air is heated to a high temperature by the dryingheater 1045. The hot air is sequentially introduced into thetub 1020 and the drum 1030 through thetub front panel 1025. The hot air dries the washing items by making contact with the washing items existing inside the drum 1030. Thereafter, the hot air used for drying the washing items is introduced into the hotair discharge duct 1047 through a hotair discharge port 1024 formed in the rear lower portion of thetub 1020. As described above, the hot air is dehumidified by the condensing water and is re-introduced into thefan 1041. Such a process may be repeatedly performed to carry out the drying operation. - In order to enhance the drying efficiency of the
drying device 1040, one end portion of the hotair supply duct 1043 may be connected to thefan 1041. The other end portion of the hotair supply duct 1043, namely the end portion of the hotair supply duct 1043 on the side of thetub front panel 1025, to which the hot air is supplied, may be connected to the front upper portion of thetub front panel 1025. In this case, the hotair supply duct 1043 may include a portion extending along the upper surface of thetub 1020 and a portion bent from the extended end portion toward the front surface of thetub 1020 to extend downward. Thus, the other end portion of the hotair supply duct 1043 may be connected to the front surface of thetub front panel 1025. - Furthermore, one end portion of the hot
air discharge duct 1047 may be connected to thefan 1041. The other end portion of the hotair discharge duct 1047, namely the end portion of the hotair discharge duct 1047 on the side of thetub 1020, through which the hot air is introduced from thetub 1020 into thedrying device 1040, may be connected to the lower rear side of the side surface of thetub 1020. In other words, the other end portion of the hotair supply duct 1043 may be biased frontward on the basis of a centerline C1 shown inFIG. 8 and may be connected to thetub front panel 1025 above a centerline C2 shown inFIG. 7 . The other end portion of the hotair discharge duct 1047 may be biased rearward on the side surface of thetub 1020 on the basis of the centerline C1 shown inFIG. 8 and may be connected to thetub 1020 below the centerline C2 shown inFIG. 7 . - By connecting the hot
air supply duct 1043 and the hotair discharge duct 1047 to the front upper portion of thetub 1020 and the lower rear side of the side surface of thetub 1020 as described above, the hot air is introduced from the hotair supply duct 1043 toward the front side of thetub 1020. After drying the washing items accommodated in the drum 1030, the hot air is discharged through the hotair discharge duct 1047 on the rear side of thetub 1020. Thus, the hot air supplied to thetub 1020 through thedrying device 1040 may be circulated through the interior of the drum 1030 as a whole. Consequently, it is possible to enhance the drying efficiency of the washing items. A waterlevel detecting sensor 1070 may be coupled to thetub front panel 1025. The waterlevel detecting sensor 1070 may be formed of, for example, a pressure sensor. The waterlevel detecting sensor 1070 may be connected to a separate pipe branched from thewater drain device 1023 of thetub 1020 and may measure the internal pressure of thetub 1020. The waterlevel detecting sensor 1070 may measure the amount of the washing water stored in thetub 1020 by sensing the internal water pressure of thetub 1020. - As one example, the water
level detecting sensor 1070 may be disposed in the front upper portion of thetub front panel 1025. In this case, the waterlevel detecting sensor 1070 may be disposed more frontward than thedrying device 1040 disposed above thetub 1020. More specifically, thefan 1041 in thedrying device 1040 may be disposed more rearward than the waterlevel detecting sensor 1070. - The water
level detecting sensor 1070 is sensitive to heat because it is formed of electronic parts. In other words, when heat of a predetermined temperature or more is applied to the waterlevel detecting sensor 1070, there is a possibility that the waterlevel detecting sensor 1070 is erroneously operated or damaged. Accordingly, it is important to set the positional relationship between the waterlevel detecting sensor 1070 and thedrying device 1040 including thedrying heater 1045 as a heat generater. - In the wall-mounted
washing machine 1000 according to one embodiment of the present disclosure, the waterlevel detecting sensor 1070 may be disposed more adjacent to thefan 1041 than the hotair supply duct 1043 of thedrying device 1040. In other words, the distance between the waterlevel detecting sensor 1070 and thefan 1041 may be shorter than the distance between the waterlevel detecting sensor 1070 and the hotair supply duct 1043. In this regard, the distance between certain two members refers to the minimum distance between the two members. When viewed as a whole, the waterlevel detecting sensor 1070 may be biased toward the hotair discharge duct 1047 of thedrying device 1040 on the basis of thedrying device 1040. - During the operation of the
drying device 1040, the air passing through thefan 1041 of thedrying device 1040 is moved along the hotair supply duct 1043 and is heated by the dryingheater 1045. Thereafter, the air passing through thetub 1020 and the drum 1030 is cooled and dehumidified by the condensing water while moving along the hotair discharge duct 1047. Thus, the temperature of the air introduced into thefan 1041 may be lowest among the temperatures of the air circulation lines of thedrying device 1040. As a result, in the wall-mountedwashing machine 1000 according to one embodiment of the present disclosure, overheating of the waterlevel detecting sensor 1070 may be prevented by disposing the waterlevel detecting sensor 1070 adjacent to thefan 1041. - Meanwhile, the
housing 1060 may be coupled to therear panel 1010. Thehousing 1060 is a member coupled to therear panel 1010 and configured to form an outer shell of the wall-mountedwashing machine 1000. Thehousing 1060 may include aside cover 1061 opened on the front and rear sides thereof and coupled to the rim of therear panel 1010 on the rear side thereof, afront cover 1062 coupled to the open front side of theside cover 1061 and provided with anopening 1062 b, and adoor 1063 rotatably coupled to thefront cover 1062 and configured to selectively close and open theopening 1062 b. - An
operation unit 1062 a may be provided in thefront cover 1062. Theoperation unit 1062 a is provided to enable a user to control the wall-mountedwashing machine 1000. Buttons of theoperation unit 1062 a may be exposed through thefront cover 1062. Theoperation unit 1062 a may be entirely disposed under thedetour rib 1027 formed in thetub front panel 1025 described above. Thus, the washing water leaked from the interior of the wall-mountedwashing machine 1000 may flow along thedetour rib 1027 without entering theoperation unit 1062 a. - A hinge coupling portion may be formed in the
front cover 1062. The hinge coupling portion may be formed on the front surface of thefront cover 1062 to be depressed at a predetermined depth. A door hinge may be coupled to the hinge coupling portion. - The
door 1063 may be provided to open and close theopening 1062 b of thefront cover 1062. For example, thedoor 1063 may be coupled to thefront cover 1062 via the door hinge. A user may close or open thedoor 1063 using a handle of thedoor 1063. Alternatively, thedoor 1063 may be an electronic door opened or closed in a one touch manner through the use of an operation button provided in thefront cover 1062. - From the foregoing, it will be appreciated that various embodiments of the present disclosure have been described herein for purposes of illustration, and that various modifications may be made without departing from the scope and spirit of the present disclosure. The exemplary embodiments disclosed in the specification of the present disclosure do not limit the present disclosure.
