An opening is provided at a position of the front wall of the housing corresponding to the detergent box for pulling out the detergent box to put in the detergent, the softener, etc. An opening is provided in the front wall of the housing at a position corresponding to the filter for taking out the filter to remove lint and the like.

The above parts are the same as those of the conventional drum washing machine, and a more detailed description thereof will be omitted.

When using the drum washing machine, a user opens the door assembly 100, puts laundry into the drum through the opening, puts detergent, softener, etc. into the detergent box, then closes the door assembly 100, sets washing, rinsing, dehydrating, etc. procedures through the man-machine interface provided in the door assembly 100, and starts a washing operation. Since the operation after the start of the washing operation is the same as that of the conventional drum washing machine, a detailed description thereof will be omitted.

The door assembly 100 of embodiment 1 will be described in detail below.

As shown in fig. 1 and 2, the door assembly 100 is provided on a case front wall of the case assembly 200 by a hinge structure so as to be openable and closable. In fig. 1, the door body assembly 100 is illustrated as being opened rightward, but it will be understood by those skilled in the art that the present invention is not limited thereto and the door body assembly 100 may be configured to be opened in any direction such as leftward, upward, downward, etc.

In the closed state, the door assembly 100 covers the front side of the case assembly 200 in the width direction over the entire range from the left side edge to the right side edge of the case front wall of the case assembly 200 in the height direction from the top surface of the case assembly 200 to at least the lowest point of the opening portion of the case front wall corresponding to the drum opening portion. Alternatively, as shown in fig. 1 and 2, the door assembly 100 may also extend from the top surface of the case assembly 200 to a position spaced apart from the bottom surface of the case assembly 200 by a predetermined distance in the height direction to provide a space avoiding portion for preventing skirting. In addition, the door assembly 100 may be disposed to entirely overlap the case front wall of the case assembly 200 in both the height direction and the width direction.

As shown in fig. 3, the door assembly 100 includes a front surface portion 110, a loading window portion 120, a cover main plate portion 130, a cover frame portion 140, and a rotation shaft portion 150. The respective components will be described below.

Front surface portion 110

The front surface portion 110 covers the entire front surface of the door body assembly 100, has a substantially rectangular shape, and may be formed of glass, acryl (PMMA, polymethyl methacrylate), or transparent ABS (acrylonitrile butadiene styrene copolymer) or the like. As shown in fig. 4 and 5, the front surface portion 110 is divided into a human interface visual area 111, an input port visual area 112, a switching key visual area 113, and other areas. The entrance visible region 112 and the on-off key visible region 113 are transparent or translucent, and the man-machine interface visible region 111 is opaque when the man-machine interface 133 is not activated, and becomes transparent or translucent after the man-machine interface 133 is activated, and is opaque in other regions.

The man-machine interface visible region 111 corresponds to a man-machine interface 133 described later. When the man-machine interface 133 is not activated, the user cannot observe the man-machine interface 133 through the man-machine interface visual area 111, and after the man-machine interface 133 is activated, the user can observe the contents displayed by the man-machine interface 133 through the man-machine interface visual area 111 and operate the man-machine interface 133, thereby further improving the external appearance of the washing machine.

The inlet visible region 112 corresponds to an inlet window 120 described later and corresponds to an opening of the drum, and a user can observe the condition of laundry in the drum through the inlet visible region 112. The switch key visual area 113 corresponds to a switch key provided in the switch module 138, which will be described later, and a user can observe the state of the switch key through the switch key visual area 113.

It should be noted that the present invention is not limited thereto, and transparent, semitransparent or opaque treatment can be performed on each region according to actual requirements, or different color treatments can be performed on each region to achieve different visual experiences. For example, the man-machine interface portion visible region 111 may be made transparent so that the man-machine interface portion 133 can be observed at any time. In addition, as described below, when the switch key is integrated in the man-machine interface part 133, the switch key visible region 113 may be omitted.

The method of processing the transparent, semitransparent or opaque treatment is not particularly limited. Alternatively, the front surface portion 110 includes glass and an opaque layer, the glass is positioned in front of the front surface portion 110, one surface is exposed, and the opaque layer is formed on the other surface, i.e., the back surface of the glass by a screen printing process or the like so as to avoid the man-machine interface visual area 111, the input port visual area 112, the on-off key visual area 113.

Wherein, the glass can be colored glass. Thus, the multicolor modeling of the washing machine can be realized by changing the color of the glass. The glass may be white glass. In this case, a colored coating is preferably provided between the back surface of the white glass and the opaque layer. The colored coating covers the whole back surface of the white glass, and the multicolor modeling of the washing machine can be realized by adjusting the color of the colored coating. The colored coating film may be provided with an adjustable transparency, and thus the man-machine interface visual area 111, the input port visual area 112, and the on-off key visual area 113 may be arbitrarily set to be transparent or translucent.

As shown in fig. 4 and 6, the input window 120 includes a window front plate 121, a window member 122, a window rear plate 123, a lock member 124, a ring lamp 125, and a ring lamp power supply 126.

The window front plate 121 has a ring surface portion 1210, an opening of which faces an opening portion of the cabinet assembly 200 for putting in and taking out laundry when the door assembly 100 is closed, and a sectional area of which becomes smaller as going from a front surface side of the door assembly 100 toward a front surface side of the cabinet assembly 200.

The annular surface portion 1210 has an inner raised portion 1211 raised with respect to the annular surface portion on substantially the entire periphery thereof, the inner raised portion being configured to be perpendicular with respect to the front surface of the door body assembly 100 and extend toward the rear surface of the door body assembly 100 when the input window portion 120 is assembled to the door body assembly 100. The inner side rising portion 1211 serves to hold the window member 122.

The annular surface portion 1210 has a first outer standing portion 1212 standing with respect to the annular surface portion at substantially the entire periphery thereof, the first outer standing portion being set to be perpendicular with respect to the front surface of the door assembly 100 when the input window portion 120 is assembled to the door assembly 100, and extending toward the rear surface of the door assembly 100. A second outer standing portion 1213 parallel to the first outer standing portion is formed on a substantially entire inner circumference of the annular surface portion on the outer edge side. A groove is formed between the first outer standing portion 1212 and the second outer standing portion 1213 for accommodating the ring lamp 125. Alternatively, a portion of the first outside rising portion 1212 is provided to be lower in height than the other portion, so that a notch is formed in the groove to take out the ring lamp 125 provided in the groove. Through the above structure, the ring lamp 125 is assembled in a back-to-front assembly manner to facilitate maintenance and disassembly.

A plurality of protrusions 1214 are provided at a position on the inner side of the annular surface portion 1210 than the second outer raised portion 1213, and the protruding direction of the plurality of protrusions is the same as the protruding direction of each raised portion. A screw portion is provided at the boss 1214 for assembling the window front plate 121 and the window rear plate 123 together by screw-bonding. For example, the window rear plate 123 is fixed to the window front plate 121 by fastening a bolt to the threaded portion after passing through a screw hole provided in the window rear plate 123.

The first outer standing portion 1212 has, on its outer surface, protrusions 1215 protruding outward at intervals, and the protrusions have screw holes penetrating the protrusions, the screw holes being used for assembling the window front plate 121 and the cover main plate 130 described later by screw-bonding, and a specific assembly method will be described later.

The manner of fixing the window front plate 121 and the window rear plate 123 and the window front plate 121 and the cover front plate 131 is not limited thereto, and any suitable manner may be adopted.

The window front plate 121 is provided with a front plate stopper (not shown) for guiding and positioning the window rear plate 123 during assembly.

Alternatively, the window front plate 121 is entirely formed of a light-uniformizing material, and as shown in fig. 11, a portion of the surface of the annular surface portion 1210 opposite to the front surface portion 110, which is inside the groove accommodating the annular lamp 125, is subjected to a plating process, so that an annular uniform light-emitting band is formed at the portion of the annular surface portion 1210 opposite to the groove when the annular lamp 125 is lighted, providing an aesthetic visual effect. Further, the portion inside the groove accommodating the ring lamp 125 may be subjected to different color treatments as needed. In addition, the window front plate 121 is not limited to being formed of a light-equalizing material, and for example, when the ring lamp 125 itself has light-equalizing performance, a transparent material having no light-equalizing performance may be used for the window front plate 121.

The window member 122 has a size equal to or slightly larger than the cross-sectional size of the inner upright portion of the window front plate 121, and has a substantially annular ring-shaped portion 1221 and a bowl-shaped portion 1222 having an arc-shaped cross-section, for example, protruding toward the bottom of the drum from above toward below. A window member stopper (not shown) for guiding and positioning the window rear plate 123 at the time of assembly is provided at the annular portion 1221 of the window member 122.

The window rear plate 123 is formed in a substantially annular shape, the annular outer edge having substantially the same size as the window front plate 121, and the annular inner edge having a size smaller than the outer edge of the annular portion 1221 of the window member 122 and equal to or larger than the inner edge of the annular portion 1221 of the window member 122, whereby the window rear plate 123 covers at least a part of the annular portion of the window member 122. A front plate stopper engaging portion (not shown) that engages with a front plate stopper portion of the window front plate 121 to perform positioning, and a window member stopper engaging portion (not shown) that engages with a window member stopper portion of the window member 122 to perform positioning are formed on the window rear plate 123. A plurality of screw holes corresponding to the bosses 1214 of the front plate are formed at the window rear plate 123 at spaced intervals, and a locking member mounting portion for mounting a locking member 124 for locking the door assembly 100 to the case assembly 200 is formed at a prescribed position. The locking member 124 and locking member mounting portion can take on structures known in the art.

The ring lamp 125 and the ring lamp power supply 126 for supplying power to the ring lamp 125 may take any configuration. Alternatively, the ring-shaped lamp 125 may be a band-shaped light source to provide a visual effect of an aperture as shown in fig. 2, or may be a structure by connecting a plurality of point-shaped light sources. Further alternatively, the lighting manner or color of the ring lamp 125 may be changed according to the operation condition of the washing machine. For example, when the washing machine fails, the ring lamp 125 is switched from continuous lighting to blinking, or from white light to red light.

The ring lamp 125 and the ring lamp power supply 126 are not necessary, and may be omitted.

The following describes the assembly process of the input window 120. The ring lamp 125 is mounted to the groove of the window front plate 121, the window member 122 is provided to the rising portion of the window front plate 121 to which the ring lamp 125 is mounted so that the bowl-shaped portion of the window member 122 faces the opposite side of the window front plate 121, and the window rear plate 123 is mounted so that the window member 122 enters the opening of the window rear plate 123. In the assembly process, the window member 122 is set at a predetermined position of the window rear plate 123 by positioning the window member stopper portion of the window member 122 and the window member stopper engaging portion of the window rear plate 123, and the window rear plate 123 is set at a predetermined position of the window front plate 121 by positioning the front plate stopper portion of the window front plate 121 and the front plate stopper engaging portion of the window rear plate 123. The window member 122 is fixed between the window front plate 121 and the window rear plate 123 by fastening bolts to the screw portions of the protrusions 1214 on the window front plate 121 after passing through the bolt holes on the window rear plate 123. The locking member 124 is attached to the locking member attaching portion of the window rear plate 123, and thereby the input window 120 is assembled.

[ Cover motherboard portion 130]

As shown in fig. 4 and 7, the cover main plate portion 130 includes a cover front plate 131, a cover rear plate 132, a man-machine interface portion 133 provided as a user interface in a space between the cover front plate 131 and the cover rear plate 132 to display and operate by a user, a proximity sensing portion 135 for sensing proximity of a human body or the like, an auxiliary power supply portion 136 for limiting standby power consumption of the entire drum washing machine, a wireless communication portion 137 for wirelessly communicating the drum washing machine with an external device, and a switch assembly 138. Wherein the switch assembly 138 is provided with a switch key, and the power of the drum washing machine can be turned on or off by operating the switch key.

The cover front plate 131 has the same shape and size as the front surface portion 110 of the door body assembly 100. The front surface of the cover front plate 131 is substantially flat for engagement with the front surface portion 110. Alternatively, a layer of elastomer may be provided between the cover front plate 131 and the front surface portion 110 so that damage can be prevented even if an impact is applied to the front surface portion 110 from the outside.

The cover front plate 131 has a central opening 1311 facing the opening of the case assembly 200 for receiving and taking out laundry when the door assembly 100 is closed. A man-machine interface opening 1312 for accommodating the man-machine interface 133 is provided above the central opening 1311. A switch key opening 1313 for receiving a switch key for turning on and off a power supply is provided on the right side of the man-machine interface opening 1312.

Of course, the installation positions of the respective portions are not limited to this, and may be set at any position of the cover front plate 131 as needed.

As shown in fig. 7, ribs having substantially the same shape as the man-machine interface 133, the switch module 138, the wireless communication unit 137, and the proximity sensor 135 are formed around the man-machine interface opening 1312, the switch key opening 1313, the wireless communication unit opening 1314, and the proximity sensor opening 1315 on the rear surface of the cover front plate 131, respectively, to accommodate these components. A screw portion is formed on the rib for fixing these components by screw coupling. Through the structure, the components are assembled in a mode of assembling from back to front, so that convenience is brought to maintenance, disassembly and assembly.

The man-machine interface 133 will be described below as an example. The man-machine interface 133 is assembled to the cover front plate 131 by disposing the man-machine interface 133 in a housing defined by the man-machine interface opening 1312 and ribs surrounding the opening, making the front surface of the man-machine interface 133 substantially flush with the front surface of the cover front plate 131, and screwing a bolt into a screw hole formed in the man-machine interface opening 133 and then into a screw thread of the rib formed around the man-machine interface opening. The method of assembling other electrical components is similar, and a detailed description thereof is omitted here.

As shown in fig. 4 and 7, a plurality of engagement portions 1316 protruding rearward are formed at the peripheral edge of the cover front plate 131 at intervals. Further, a plurality of rearwardly protruding projections 1317 are formed at intervals, and cover front plate screw holes for screw-fixing the cover front plate 131 and the cover rear plate 132 are formed in the projections. Further, a boss protruding rearward is formed at a position on the rear surface of the cover front plate 131 corresponding to the screw hole of the protruding portion 1215 of the window front plate 121, and a screw portion for assembling the window front plate 121 and the cover front plate 131 is formed at the boss.

The cover back plate 132 has the same shape and size as the cover front plate 131. The cover rear plate 132 has an opening facing the opening of the case assembly 200 for receiving and taking out laundry when the door assembly 100 is closed.

A rotary shaft portion mounting portion formed as a recess is provided on the rear surface of the cover rear plate 132 at two positions spaced apart by a predetermined interval on the side opposite to the side on which the locking member 124 is mounted. A screw hole is provided in the shaft portion mounting portion, and a shaft portion 150, which will be described later, for allowing the door assembly 100 to be opened and closed with respect to the case assembly 200 is mounted by screw-coupling. The shaft portion mounting portion is formed with an opening through which a lead 160 (see fig. 10) passes, and the lead 160 is used for power supply, data transmission, and the like.

A flange protruding forward is formed on substantially the entire edge of the cover rear plate 132. A concave structure portion having a reinforcing rib structure is formed at the opposite side of the rotation shaft portion mounting portion of the flange for forming a knob portion that a user pulls to open and close the door body assembly 100. The specific location of the clasp is not limited and may be provided, for example, on or to the side of the cover back plate 132. An engagement portion for engaging with the engagement portion is formed at a position of the flange corresponding to the engagement portion of the cover front plate 131. A cover rear plate screw hole for screw-fixing the cover front plate 131 and the cover rear plate 132 is formed at a position of the flange corresponding to the cover front plate screw hole of the cover front plate 131.

The cover front plate 131 and the cover rear plate 132 are connected by being engaged with each other by an engagement portion formed on the cover front plate 131 and an engagement portion formed on the cover rear plate 132. The lid rear plate screw hole of the lid rear plate 132 and the lid front plate screw hole of the lid front plate 131 can be screwed together by bolts. Here, the screw tightening is not necessarily required, and if the engaging force obtained by engaging the engaging portion with the engaging mating portion is sufficient, the screw fixation may be omitted.

The cover front plate 131 and the cover rear plate 132 are used to clamp and fix the input window 120 therebetween.

Here, the description will be made in terms of the manner in which the respective members of the input window portion 120 and the cover main plate portion 130 are formed independently and assembled. However, the present invention is not limited thereto, and a part of the members may be integrally formed, and for example, the window front plate 121 and the cover front plate 131 may be integrally formed and assembled by substantially the same method as described above.

The structures and positions of the man-machine interface 133, the proximity sensing unit 135, the auxiliary power unit 136, the wireless communication unit 137, and the switch unit 138 are not limited, and any suitable structure and/or arrangement may be adopted.

Alternatively, the man-machine interface part 133 may employ an electrostatic capacitive touch panel, and include a transparent electrode, a liquid crystal panel, and a control substrate for controlling the transparent electrode and the liquid crystal panel. Here, the LED integrated module may be a flat or substantially flat display panel which can be controlled by the control unit to display, and may be used, not limited to a liquid crystal panel, but an LED (LIGHT EMITTING diode) panel.

When the user touches the man-machine interface visible region 111 of the front surface portion 110 with a finger, the transparent electrode detects a change in capacitance when the finger touches the man-machine interface visible region 111, whereby the position of the finger touch can be specified, and the display content can be changed in accordance with the user's operation.

Here, the change in capacitance is determined by the dielectric constant of the substance touched by the finger, and the higher the dielectric constant is, the larger the change in capacitance is, and the higher the sensitivity is. The high sensitivity means that the position pressed by the finger can be accurately and quickly recognized. Further, for example, it means that false detection in which the water droplets adhering to the water droplets are recognized as being touched by a finger is not likely to occur, and false detection due to the influence of external noise is not likely to occur.

For example, glass has a dielectric constant of about 9, and ABS resin and PET resin have a dielectric constant of about 3, and the change in capacitance is inversely proportional to the thickness. Thus, for example, when the material of the portion touched by the finger is a glass plate, the same sensitivity can be obtained even if the thickness is 3 times as large as that of ABS resin or PET resin. Therefore, when the man-machine interface 133 is a capacitive touch panel, the material of the front surface 110 is preferably glass.

Alternatively, the man-machine interface portion 133 may be provided such that the front surface is directly bonded to the front surface portion 110, or as shown in fig. 8, an elastic body 127 may be provided around the man-machine interface portion opening 1312, and the front surface portion 110 and the man-machine interface portion 133 may be assembled together in a state in which the elastic body 127 is pressed to be deformed. At this time, the interval between the front surface of the man-machine interface part 133 and the rear surface of the front surface part 110 is preferably not more than 0.5mm. The elastic body 127 may be a sponge. With this structure, moisture can be prevented from entering the man-machine interface 133.

In another modification, the man-machine interface 133 may be further provided to include a glass plate provided on the front surface, and the transparent electrode may be adhered to the back surface of the glass plate. As in the above, such a man-machine interface 133 may be provided directly to the front surface portion 110 or adjacent to the front surface portion 110 via an elastic body. In the case of this structure, the man-machine interface 133 becomes a separate component, greatly reducing the environmental requirements and difficulty of assembly.

In the above description, the man-machine interface 133 is directly fixed to the cover front plate 131 by bolts. Alternatively, the man-machine interface 133 may also be fixed to the cover front plate 131 by bolts with spring washers. With this structure, the environmental requirement and difficulty of assembly are greatly reduced, and touch sensitivity can be easily ensured.

Similarly, the switch key of the switch assembly 138 may also be a capacitive touch panel. When the user touches the switching key visual area 113 with a finger, the switching assembly 138 detects the generated change in electrostatic capacity and switches the switching key between on and off.

Alternatively, the proximity sensing part 135 may employ infrared sensing to determine whether a human body is in proximity by actively projecting infrared light and detecting reflection of the infrared light. In this case, in order to improve the detection accuracy, the material of the portion of the front surface portion 110 facing the proximity sensing portion 135 may be replaced with a material having higher infrared transmittance than the material of the other portion.

When the proximity sensing part 135 detects that there is a human body proximity, a signal may be transmitted to the auxiliary power supply part 136, so that the auxiliary power supply part 136 causes the ring lamp 125 to be lighted or supplies power to the switch assembly 138 to light the switch key of the switch assembly 138. Also, in order to avoid false detection, the proximity sensing part 135 may be provided to transmit a signal to the auxiliary power supply part 136 only when a human body is detected within a relatively close predetermined distance range. Further, an operation portion for a user to close or open the proximity sensing portion 135 may be provided.

The auxiliary power supply 136 is used to supply power to the proximity sensing part 135, the wireless communication part 137, the switch assembly 138, and other components that need to be on standby when the washing machine is in an unused state, so that the main power supply part that supplies power to the washing machine as a whole can be turned off, thereby controlling the standby power consumption of the washing machine to be 1W or less to meet the regulations of the relevant national standards. The specific circuit configuration is not limited, and any known configuration capable of realizing the above functions may be employed. The installation method is not limited, and may be a separate component as described above, or may be integrated into other circuit configurations such as a main power panel.

In the case where the auxiliary power supply 136 is a separate component, it is preferable to provide the auxiliary power supply 136 without greatly changing the configuration of the conventional circuit, since the standby power consumption can be reduced and the versatility is high.

The switch assembly 138 may be configured to be always powered by the auxiliary power supply 136 when the washing machine is in an unused state so that the switch key is always in an operable state, or may be configured to be powered from the auxiliary power supply 136 when a human body is detected to be approaching the washing machine through the approach sensing part 135 so that the switch key is in an operable state.

Here, the purpose of the auxiliary power supply 136 and the switch assembly 138 is to limit standby power consumption of the washing machine. It is known to those skilled in the art that the auxiliary power supply 136 and the switch module 138 may be omitted and the switch key may be integrated in the man-machine interface 133, even when these components are not provided, in a case where the standby power consumption of the washing machine is controlled to meet the specifications of the national standard, or in a case where the standby power consumption is not required to be considered.

The proximity sensor 135 and the wireless communication unit 137 are not necessarily required, and may be omitted to reduce the cost, or may be provided in the case assembly 200. Alternatively, the proximity sensing part 135 may be provided at a portion of the lower side of the case assembly 200, which is not covered by the door assembly 100.

However, as will be appreciated by those skilled in the art, these numbers and positions are merely exemplary, and the present invention is not limited thereto, and the number and arrangement positions of these components may be arbitrarily set according to actual needs.

Further, as means for fixing the lower bezel to the main board of the cover, L-shaped hooks 1444, 1445, 1446, holes 1442 through which bolts pass are exemplified. However, as will be appreciated by those skilled in the art, the above structure is merely exemplary and the present invention is not limited thereto and some or all of the L-shaped hooks 1444, 1445, 1446 may be eliminated.

Through above-mentioned structure, need not to form the hole that supplies the bolt to pass at last frame, left side frame and right frame, go up frame, left side frame and right frame and be fixed to the cover mainboard through the mode of block, fasten through the bolt on the lower frame that the customer is difficult to see only, make the outward appearance of door body subassembly more pleasing to the eye from this.

The shape of the cover main board 130, the structure of the cover frame portion 140, and the manner and order of attachment to the cover main board of the present invention are not limited to those described above as examples. Any suitable structure and installation method may be used for the cover main board 130 and the cover frame portion 140.

For example, alternatively, the cover main plate 130 may not be formed in a substantially rectangular shape, but may be in a circular shape, for example. In this case, the cover rim 140 is also formed in a circular shape. The cover frame portion 140 may not include the upper frame, the left frame, the right frame, and the lower frame as described above, but may be formed as an arc-shaped member that matches the shape of the cover main plate 130 and can cover at least the upper portion, the left side surface, and the right side surface of the cover main plate. In the mounting process, the notch of the arc-shaped member is opposed to the bottom of the cover main plate 130. A clip is formed at both ends of the arc-shaped member, and the arc-shaped member is fixed to the cover main plate 130 by engagement of the clip with a clip groove formed at a corresponding position of the cover main plate.

The engagement structure between the cover frame 140 and the cover main plate 130 is not limited to the above-described structure, and any suitable engagement structure may be employed. For example, the cover frame 140 may be engaged with the cover main plate 130 by providing a protruding portion as the engaged portion and providing a U-shaped portion as the engaged portion, and inserting the protruding portion into the U-shaped portion to elastically deform the U-shaped portion. Alternatively, a U-shaped portion may be provided on the cover rim portion 140, and a protruding portion may be provided on the cover main plate 130. The positions of the engaging portion and the engaged portion are not limited to the end portions of the respective frames. For example, when the above-described protruding portion and U-shaped portion are used as the engaging portion and the engaged portion, the protruding portion and U-shaped portion may be provided at the end portion or may be provided at any position other than the end portion.

Further, the structures of the upper frame, the left frame, the right frame, and the lower frame are not limited to the above examples. Alternatively, the bending portion may not be formed at the upper frame, or may be formed at the ends of the left and right frames. Alternatively, the upper frame, the left frame, the right frame, and the lower frame may not form the flange portion.

In addition, the installation of the lower frame may be omitted.

Further, as will be appreciated by those skilled in the art, although the above description has been made of the door body assembly of the present invention applied to a drum washing machine, the door body assembly of the present invention may be applied to other laundry treatment apparatuses and other electric appliances such as a refrigerator.

[ Shaft portion 150]

As shown in fig. 10, the door assembly 100 includes two shaft portions 150 provided at two predetermined positions in the height direction. The structure of each shaft portion is the same, and only one shaft portion 150 will be described here. The rotation shaft portion 150 includes a connection frame 151, a mounting plate 152, a sleeve 153, and a lead groove 154.

The connection frame 151 includes a base portion 1511, an arm portion 1512, and a shaft portion 1513. The base portion 1511 is substantially rectangular, and screw holes are formed therein for fastening the base portion 1511 to the case front wall of the case assembly 200 by bolts to attach the connection frame 151 to the case assembly 200. An opening through which the lead 160 passes is formed in the base portion 1511 at a portion connected to the arm portion 1512. The arm 1512 is a substantially L-shaped member including a first portion connected to the base portion 1511 and substantially perpendicular to the base portion 1511, and a second portion continuous with the first portion through a curved portion and substantially parallel to the base portion 1511. The arm portion 1512 is formed with a recess opening downward, one end of which communicates with the opening of the base portion 1511, and the other end extends below the shaft portion 1513 for receiving a lead groove 154 to be described later. At an end of the arm 1512 opposite to the base 1511, a shaft 1513 is provided so as to be upright in parallel with the base 1511.

The mounting plate 152 includes a base portion 1521 and a protruding portion 1522. The base portion 1521 is substantially rectangular, and has a screw hole formed therein for fastening the base portion 1521 to the shaft portion mounting portion of the cover rear plate 132 by bolts to fix the mounting plate 152 to the door assembly 100. Two protruding portions 1522 protruding rearward and extending in parallel so as to be perpendicular to the base portion 1521 are formed at one end portion of the base portion 1521. Holes for mounting the boss 153 are provided at corresponding positions of the two protrusions 1522.

The boss 153 is formed of a soft material such as POM (polyoxymethylene) or PET (polyethylene terephthalate) or PA66 (polyamide 66) or EPDM (ethylene propylene diene monomer), and has a hole into which the shaft portion 1513 of the connection bracket 151 is inserted, and a buckle for locking the boss 153 into the hole of the mounting plate 152 to prevent the boss 153 from falling off.

The lead groove 154 is provided as a groove having substantially the same shape as the groove of the connection frame 151. A plurality of projections extending in a direction intersecting the extending direction of the grooves and parallel to the bottom surface of the grooves are arranged in the grooves, and the lead 160 is routed between each projection and the bottom surface of the groove. With this structure, the lead is prevented from directly contacting the connection frame 151 while the lead is fixed, so that the lead can be effectively protected.

One end of the lead groove 154 is insertable into an opening of the base portion 1511 of the connection frame 151 and provided with a notch through which the lead 160 can pass and be connected to various components within the case assembly 200. The other end of the lead groove 154 has a cylindrical portion which is substantially concentric with the shaft portion 1513 of the connection frame 151 and protrudes in a direction opposite to the shaft portion 1513. The cylindrical portion communicates with a groove for accommodating the lead 160. A slit extending in the height direction from the upper end surface of the lead groove 154 to the lower end surface of the cylindrical portion is formed at the side end portion of the lead groove 154. With this gap, the lead 160 can be easily taken out from the lead groove 154 or the lead 160 can be put into the lead groove 154, and the direction of the lead 160 can be easily turned by the cylindrical portion. The lead groove 154 is further provided with a buckle for preventing the lead groove 154 from falling off when the lead groove 154 is inserted into the groove of the connection frame 151.

Alternatively, the hinge portion mounting portion of the cover rear plate 132 may be covered with the cover plate 134 after the door assembly 100 is mounted to the case assembly 200, and the cover plate 134 simultaneously covers the leads, preventing the user from directly contacting the leads to induce electric shock. In addition, the cover 134 limits the stroke of the up-and-down movement of the shaft portion 1513, thereby preventing the door assembly 100 from being detached from the case assembly 200 due to a large shock or an unintentional action of the user.

When the rotation shaft portion 150 is mounted, the lead 160 extending from the opening of the case assembly 200 is fixed between the plurality of parallel protrusions in the lead groove 154, the lead groove 154 is inserted into the groove of the connection frame 151 and is locked by the snap fastener, the connection frame 151 is mounted to the case assembly 200 in a state that the shaft portion 1513 is upward by the bolt, the boss 153 is inserted into the hole of the mounting plate 152 and is locked by the snap fastener itself, then the mounting plate 152 is mounted on the rotation shaft portion mounting portion of the cover rear plate 132 by the screw-coupling, the shaft portion 1513 on the connection frame 151 is inserted into the boss 153, and the plug portion provided at one end of the lead 160 is inserted into the socket portion provided to the door assembly 100, thereby electrically connecting the case assembly 200 to the door assembly 100. Finally, the cover plate 134 is attached to the shaft portion attaching portion of the cover rear plate 132.

In this way, the aperture of the mounting plate 152 forms a swing pair with the shaft portion 1513 of the connection bracket 151 so that the door assembly 100 can be opened and closed with respect to the case assembly 200.

In the present invention, the two shaft portions 150 have the same structure, and the shaft portions 1513 of the connecting frame 151 face the same direction (upward or downward) when they are attached, and are easy to detach as compared with the conventional structure in which the shaft portions are attached so as to face each other. In addition, the shaft sleeve 153 prevents the mounting plate 152 and the connecting frame 151 from directly contacting and rubbing to generate high-frequency noise.

The structure, mounting manner, and order of the shaft portion 150 of the present invention are not limited to those described above as examples. The rotation shaft portion 150 may be of any suitable structure and attachment method as long as the door assembly 100 can be connected to the box assembly 200 to be opened and closed.
