Description

The technical field to which the invention relates.

The present invention relates to a device for processing linen, having a door for opening and closing the opening for loading linen body.

Prior art

The laundry treating device may include a laundry washing device, a laundry drying device, and a laundry washing / drying device at the same time. In the laundry treating device, washing the laundry is a cycle of removing contaminants adhering to the laundry, due to the action between water and detergent, and drying the laundry is a cycle of removing moisture contained in the laundry using a hot air supply device located in the laundry treating device .

A typical laundry treating device may include a body configured to form its appearance and containing an opening for loading laundry, a laundry positioning area formed in the housing, a drive unit configured to rotate the drum forming the laundry positioning area, a door made with the possibility of opening and closing the opening for loading the linen, and the control unit configured to display visual information associated with the cycle performed in the device for processing linen for the user and receiving user commands.

Such a typical laundry treating device is intended to perform an internal function, providing opening and closing of the laundry opening and observation of the laundry placement area. In addition, the control unit is usually located on the housing and contains a plurality of buttons or knobs for briefly displaying only specified cycles through on / off or the like and manipulating them.

The distinction between the door and the control unit interfered with the simple appearance of the laundry treating device, and the input and output interfaces between the laundry treating device and the user were rather low.

As a result, studies were conducted on the placement of the control unit on the door and the implementation of the control unit with a touch screen. Related technologies can also be found in Korean patent publication no. 10-2011-0130089 (published December 5, 2011) and 10-2015-0006264 (published January 16, 2015). However, studies on the overall aesthetic appearance of the door and the touch screen, as well as the design of the door, which causes a new sensation at a low price, are still not entirely satisfactory.

In addition, glue is commonly used to join the door cover to the door frame along with a mechanical fastener design using a bracket, hook or the like. However, when the door lid with glass is used to evoke a high-quality feeling, it is difficult to use such a mechanical fastener design. In addition, when the door is made in a round shape, difficulties also arise in choosing a position for the correct installation of the door frame.

In addition, glue may leak during the process of connecting the door cover to the door frame with glue, thus causing a deterioration in appearance quality. To prevent a problem, glue can be applied to the inside of the door frame, located at a great distance from its edge, but this can lead to a deterioration in the strength of the joint, and has a problem causing easy penetration of foreign substances through the gap between the door cover and the door frame.

On the other hand, in the aspect in which the door has a design for opening and closing the laundry load hole when the touch screen is located on the door, moisture is likely to penetrate the electronic elements forming the touch screen. Accordingly, the sealing of electronic elements can be an important point in the aspect of ensuring the reliability of control of the touch screen.

The display unit 130 is located to correspond to the second opening 111b, and the indicator 132 located in the display unit 130 is configured to display visual information associated with the information processed in the laundry treatment device 1.

In addition, an FPCB hole 111c, through which the flexible printed circuit board (FPCB) of the tactile sensor 160 can pass, can be formed on the door frame 110. According to this drawing, it is shown that the FPCB hole 111c is located on one side of the second hole 111b .

The door cover 140, which forms the appearance of the door 10, is connected to the door frame 110. The door cover 140 may be made of glass or synthetic resin having light transmitting characteristics.

The door lid 140 may include a light-transmitting region 143, and a first light-transmitting region 141 corresponding to the first aperture 110a, and a second light-transmitting region 142 corresponding to a second aperture 111b. In this document, the light-transmitting area (or transparent area) means an area made with the possibility of passing at least part of the world, through which its opposite side or its inner side is visible.

The first and second light-transmitting areas 141, 142 are separated from each other by an area 143 that does not transmit light. In accordance with the present embodiment, it is shown that the door frame 110 and the door lid 140 are formed in a circular shape for connection with the door 10 having a circular shape, and the first and second light-transmitting regions 141, 142 are formed in a circular shape to evoke a general aesthetic feeling user In this document, the round shape may include a regular round shape, an oval shape, or a rounded shape, in which at least part of it is made in a rounded shape.

As reference information, the above configurations made in a round shape are presented as an embodiment, but the present disclosure may not necessarily be limited to this. For example, the first and second light-transmitting regions 141, 142 may be formed in a polygonal shape (rectangular, hexagonal shape, or the like) or other geometric shapes, as well as in a circular shape.

The door cover 140 can be designed in such a way that at least part of it has a curved shape. For example, the first portion of the lid and the second portion of the lid on both sides of the curved portion may be formed with a slope relative to each other due to the curved portion. In this document, the first portion of the lid and the second portion of the lid are made in a flat shape. Door frame 110 can also be designed in such a way that at least part of it is curved to fit door cover 140.

In accordance with this embodiment, it is shown that the first light transmitting region 141 is formed within the first portion of the cover and the curved portion, and the second light transmitting region 142 is formed in the second portion of the cover.

On the other hand, the second light-transmitting region 142 is formed smaller than the size of the second opening 111b, and is positioned to overlap with the second opening 111b in a position in which the door lid 140 is connected to the door frame 110. In this document, the overlap means the overlap in the thickness direction of the door 10. Due to this construction, the outer line forming the second opening 111b may be hidden and not visible due to the area 143 that does not transmit light.

In addition, the display unit 130 is mounted on the second aperture 111b, and the second light transmitting area 142 may be located for overlapping in the indicator 132 located in the display unit 130. In accordance with this design, only the indicator 132 displayed with visual information can be opened to the outside, and other structures (for example, the support frame 131) may not be open to the outside due to the area 143 not transmitting light to provide more simple appearance of the door 10.

In addition, the edge area (i.e., the frame area) of the indicator 132 corresponds to an area in which visual information is not substantially displayed due to the limitation of its design. If the edge region is located in the second light transmitting region 142, then the visual information displayed on the indicator 132 forms a smaller screen than the screen of the second light transmitting region 142. In this case, the user may feel that the screen displayed by the visual information is smaller than the screen .

To solve such a problem, an edge on which visual information is not displayed on the indicator 132 may be located for closure by the non-transmissive region 143. In accordance with this design, the visual information displayed on the indicator 132 forms a (full) screen that fully corresponds to the second light transmitting area 142. In this case, the user may feel that the screen displayed by the visual information is larger than the screen, thus enhancing user interest in the screen.

As shown in the drawing, the second opening 111b is formed in a rectangular shape corresponding to the display unit 130 having a rectangular shape, and the second light transmission region 142 is formed in a circular shape arranged to overlap in the second opening 111b. In other words, the second light-transmitting area 142 is located to overlap with part of the display unit 130, and the area 143 that does not transmit light is located to close another part of the display unit 130. Due to the above construction, the visual information can only be displayed on the portion corresponding to the second light transmitting region 142, which has a round shape, to form the display portion 12, which has a circular shape, for the user.

The cost of a round indicator is higher than the cost of a rectangular indicator 132, which is widely used, and its damage during assembly can often arise due to difficulties in determining the exact installation position due to its shape. However, in accordance with the above construction, it may be possible to form a display section 12, which is visible as a round shape, for a user using a low cost rectangular indicator 132 that can be assembled in a precise position.

The second light-transmitting area 142 is surrounded by an area 143 that does not transmit light, and thus the visual information displayed on a portion that does not correspond to the second light-transmitting area 142 in the indicator 132 is not visible to the user. Taking this into account, visual information may not be displayed on a site that does not correspond to the second light transmitting area 142 in the indicator 132.

For example, an image of the edge surrounding the visual information may be displayed on a portion that does not correspond to the second light transmitting area 142 in a position in which the visual information associated with the information processed in the laundry treating device 1 is displayed on the portion corresponding to the second light transmitting region 142. The image of the edge in the form of a portion that does not correspond to the second light-transmitting region 142 may be filled with a specific series of colors (for example, black).

As another example, a portion that does not correspond to the second light-transmitting region 142 may be configured to be removed from a position in which visual information associated with information processed in the laundry treating device 1 is displayed in the portion corresponding to the second light-transmitting region 142. In other words, the image of the edge, as well as visual information is not displayed in the area that does not correspond to the second light transmitting area 142 in the display unit 130. In accordance with this example, only a portion of the indicator 132 can be activated to ensure the efficient operation of the indicator 132 compared to the above example, in which the entire indicator 132 is activated, thereby obtaining an energy saving effect.

FIG. 5 is a rear view of the door cover 140 shown in FIG. 3. FIG.

The display portion 12 formed on the door cover 140 may form a sublayer or an integral structure with a tactile sensor 160 for implementing the touchscreen 12. The touchscreen 12 may provide an output interface between the laundry treatment device 1 and the user, while simultaneously performing the function of the device an input providing an input interface between the laundry treatment device 1 and the user. For example, selecting and modifying an operating mode for performing washing cycles, removing moisture, drying, and the like, may be accomplished through user input (or touch).

The tactile sensor 160 is located on the door 10 to detect sensory input to the door cover 140.

The tactile sensor 160 determines a touch input applied to a display area (or touch screen) 12 using at least one of various touch methods such as resistive method, capacitive method, infrared method, ultrasonic method, magnetic method, and the like.

For example, the tactile sensor 160 may be configured to convert a change, such as pressure applied to a particular portion of the touch screen 12 or a capacitance generated at a particular portion, or the like, into an electrical input signal. The tactile sensor 160 may be configured to determine the position, area, pressure during touch or the like, in which the touch object using the touch on the display portion 12 relates to the tactile sensor 160. In this document, the touch object as an object using the touch tactile the sensor 160 may include a finger, a stylus for a touch screen, or a touch pen, a pointer, and the like, for example.

When there is a touch input to a tactile sensor 160, as described above, the signal (s) corresponding to it was sent to the controller. The controller can process the signal (s) and then transmit the corresponding data to the controller (not shown). As a result, the controller may know which areas of the display portion 12 were touched or the like. In this document, the controller can be an optional device for the controller or the controller itself.

On the other hand, the controller may perform another control operation according to the type of the touch object relating to the display section 12, or perform the same control operation. Whether performing another control operation or performing the same control operation according to the type of touch object can be determined according to the operational status of the laundry treatment apparatus 1 or the application program being executed.

The tactile sensor 160 can detect various types of touches, such as a short or light touch touch, long touch, multiple touch, slow touch, fast touch, touch with burning, touch with sliding, touch with holding the finger in the horizontal direction, touch with pointing and the like.

The tactile sensor 160 is configured to determine a sensory input to the sensor area, including the second light transmitting area 142.

In accordance with this embodiment, it is shown that the tactile sensor 160 is glued to the back surface of the door cover 140 to close the second light transmitting area 142 and part of the area 143 that does not transmit light surrounding the second light transmitting area 142. In accordance with the above design, the touch area of the tactile sensor 160 may include a portion of the area 143 that does not transmit light surrounding the second light-transmitting region 142, as well as the second light-transmitting region 142. Accordingly, it may be possible Providing various user interfaces or graphical user interfaces using part of the area 143 that does not transmit light surrounding the second light transmission area 142.

In accordance with the above construction, the tactile sensor 160 may be made in the form of a sensor film having a touch pattern and located between the door cover 140 and the display unit 130. The sensor film may be made of a transparent conductive film, and previously known films, such as an indium and tin oxide film (ITO), a carbon nanotube film (CNT), or the like, can be used for a sensor film.

The sensor film can be made with a single or double layer. For example, when the sensor film is a glass-film-film (GFF) film with a double layer, the sensor film may be glued to the back surface of the door cover 140 or glued to the display unit 130. As another example, when the sensor film is a glass film (G1F) film with a single layer, the sensor film may be glued to the back surface of the door cover 140 and made as one piece with the door cover 140.

The tactile sensor 160 can be designed in such a way that the metal wire directly forms a pattern on the back surface of the door cover 140 without an additional touch film (glass only (G2)).

Alternatively, the tactile sensor 160 may be made in one piece with the indicator 132 located in the display unit 130. For example, the tactile sensor 160 may be located on the substrate of the indicator 132 (per cell) or located in the indicator 132 (in the cell).

On the other hand, the operation of the display portion 12 of the laundry treating device 1 is controlled by the controller. In other words, the controller 180 controls on / off display unit 130, and an indicator of visual information or image and controls on / off of the tactile sensor 160.

In this document, the controller can be configured to control whether to activate the contact recognition in an area that does not correspond to the second light transmitting area 142 in the sensor area of the tactile sensor 160. For example, the controller can be configured to recognize the position in which the contact identifying a region that does not correspond to the second light transmitting region 142 in the sensor region of the tactile sensor 160 is necessary based on the position in which the contact identification Maintenance is not required for decontamination for inappropriate contact identification area in a position in which the contact recognition is not required. In accordance with the control, it may be possible to reduce the error of touch input by the user and obtain the effect of saving energy.

FIG. 6 is a sectional view of the first embodiment of the door cover 140 along line A-A ′ shown in FIG. 5.

As shown in FIG. 6, the door cover 140 may include a housing 140a and a protective layer 140b.

The cover body 140a may be made of a light-transmitting material. The cover body 140a may be made of light-transmitting glass or synthetic resin. The cover body 140a may be made in a form in which at least a part of it is bent.

A protective layer 140b is disposed to cover one surface of the cover body 140a to form a light impermeable area 143. The protective layer 140b may be formed on the front surface or the rear surface of the cover body 140a.

In accordance with this embodiment, it is shown that the ink is printed on the back surface of the cover body 140a to form the protective layer 140b. The ink may include a pigment having a specific set of colors (eg, black, white, blue, etc.). For the method of forming the protective layer 140b, a variety of printing methods, such as screen printing (using a mesh formed of silk, nylon, a mixture of polyester and viscose, stainless steel, etc.), offset printing, transfer printing or the like, can be used in him

As shown in the drawing, the protective layer 140b is not located in the first and second light-transmitting regions 141, 142. In other words, the first and second light-transmitting regions 141, 142 are transparent portions remaining in the form of a light-transmitting cover body 140a without being covered by the protective layer 140b.

The protective layer 140b is formed to surround the first and second light-transmitting regions 141, 142, and the first and second light-transmitting regions 141, 142 are separated from each other by an area 143 that does not transmit light, formed by the protective layer 140b.

The tactile sensor 160 is glued to the back surface of the cover body 140a corresponding to the second light transmitting area 142. The tactile sensor 160 is located to completely close the second light transmitting area 142 and is configured to detect sensory input to the second light transmitting area 142. The tactile sensor 160 can be formed larger, than the size of the second light transmitting region 142. In this document, the tactile sensor 160 may be configured to close a portion of the protective layer 140b to limit the watts. a swarm of light-transmitting region 142.

Due to the above construction, a tactile sensor 160 having a light transmitting characteristic and a lid body 140a having a translucent characteristic are arranged in series on the front side of the indicator 132 located in the display unit 130.

FIG. 7 is an enlarged view of the portion “B” shown in FIG. 5. FIG.

As shown in FIG. 7, the translucency of the protective layer 140b to limit the first light transmitting area 141 in the door cover 140 can be formed to gradually change when placed closer to the first light transmitting area 141.

For example, the area 143, not transmitting light, near the first light transmitting area 141, can be made with the possibility of a gradual light transmission at a closer location to the first light transmitting area 141. For this purpose, the protective layer 140b may include a plurality of security points 140b 'formed near the first light transmitting region 141, and the density of the plurality of security points 140b ′ can be formed so as to decrease with a closer arrangement to the first light transmitting region 141.

By blurring the boundary of the first light-transmitting region 141 using such a halftone method, the region 143, which does not transmit light, can visually and naturally change to the first light-transmitting region 141.

On the contrary, the second light-transmitting region 142 and the region 143, not transmitting light, made with the possibility of its environment, can be clearly separated as a boundary line of the region 143, not transmitting light.

FIG. 8 is a sectional view of a second embodiment of the door cover 140 along line A-A ′ shown in FIG. 5.

Unlike the aforementioned first embodiment, in which the protective layer 140b is printed on the back surface of the cover body 140a, in accordance with this embodiment, the film 2140b for forming the light-transmitting area 2143 can be adhered to the back surface of the cover body 2140a.

As shown in the drawing, the film 2140b may include a section 2140b3 not transmitting light corresponding to the area 2143 not transmitting light, a first light-transmitting section 2140b1 corresponding to the first light-transmitting area 2141, and a second light-transmitting section 2140b2 corresponding to the second light-transmitting area 2142. Section 2140b3, not transmitting light, is formed to surround the first and second light-transmitting sections 2140b1, 2140b2, and the first and second light-transmitting sections 2140b1, 2140b2 are separated from each other by section 2140b3, do not miss light.

In this document, the portion corresponding to the non-transmissive portion 2140b3 serves as a protective layer to ensure the opacity of the door cover 2140 to form the non-transmissive region 2143. The portion corresponding to the first and second light-transmitting portions 2140b1, 2140b2, forms the first and second light-transmitting regions 2141, 2142, respectively, together with the light-transmitting cover case 2140a.

In other words, unlike the above-mentioned first embodiment, the first and second light-transmitting regions 2141, 2142 are formed by providing the first and second light-transmitting portions 2140b1, 2140b2, respectively, which are transparent portions of the film 2140b to be placed on the light-transmitting cover body 2140a.

The tactile sensor 2160 is glued to the back surface of the film 2140b, corresponding to the second light transmission portion 2140b2. The tactile sensor 2160 is located to completely close the second light-transmitting area 2142 and is configured to detect sensory input to the second light-transmitting area 2142. The tactile sensor 2160 can be formed larger than the size of the second light-transmitting area 2142, and therefore the tactile sensor 2160 can be made with the possibility of closing part of the section 2140b3, not transmitting light, to limit the second light-transmitting section 2140b2.

Due to the above construction, a tactile sensor 2160 having a light transmitting characteristic, a second light transmitting portion 2140b2 of the film 2140b, and a lid body 2140a having a light transmitting characteristic are arranged sequentially on the front side of the indicator 132 located in the display unit 130.

FIG. 9 is a sectional view of a third embodiment of the door cover 140 along line A-A ′ shown in FIG. 5.

Similar to the above-mentioned second embodiment according to this embodiment, the film 3140b for forming the protective layer 3140b can be glued to the back surface of the cover body 3140a. As shown in the drawing, the film 3140b may include a section 3140b3 not transmitting light corresponding to the area 3143 not transmitting light, a first hole 3140b1 corresponding to the first light-transmitting area 3141, and a second hole 3140b2 corresponding to the second light-transmitting area 3142. The section 3140b3 not light transmitting is formed to surround the first and second openings 3140b1, 3140b2, and the first and second openings 2140b1, 2140b2 are separated from each other by a section 3140b3 that does not transmit light.

In this document, the portion corresponding to the non-transmissive portion 3140b3 serves as a protective layer to ensure the opacity of the door lid 3140 to form the non-transmissive region 3143. The first and second openings 3140b1, 3140b2 are formed in areas corresponding to the first and second light-transmitting areas 3141, 3142, so the film 3140b should not be placed on them, allowing the light-transmitting body 3140a to remain.

The tactile sensor 3160 is glued to the back surface of the film 3140b corresponding to the second light transmitting area 3142. The tactile sensor 2160 is positioned to completely close the second light transmitting area 3142 and is configured to detect sensory input to the second light transmitting area 3142. The tactile sensor 3160 can be formed larger than the size of the second light-transmitting region 3142, and, therefore, the tactile sensor 3160 can be made with the possibility of closing part of the section 3140b3, which does not transmit light, for og anicheniya second light aperture 3140b2.

Due to the above construction, a tactile sensor 3160 having a light transmitting characteristic and a cover body 3140a having a light transmitting characteristic are arranged in series on the front side of the indicator 132 located in the display unit 130. There is a slight difference from the layered structure shown above, in FIG. 6, through the thickness of the protective layer 140b, but it appears to be essentially the same.

The above layered structure shown in Fig.6 and 9, has the following advantage compared with the aforementioned design shown in Fig.8.

First, the tactile sensor 160, 3160 can be directly glued to the transparent cover body 140a, 3140a, thus increasing the user's tactile sensitivity. In addition, unlike the above-mentioned layered structure shown in FIG. 8, the second light-transmitting portion 2140b2 of the film 2140b may not be located on the front side of the indicator 132, thus more clearly displaying visual information on the indicator 132.

In this case, the method of fixing the film 2140b, 3140b on the door cover 2140, 3140, shown in FIGS. 8 and 9, can be cast in a mold, a transfer method, and the like.

Mold casting is a method that can be used when the door lid 2140, 3140 is made of synthetic resin, that is, in a manner in which the film 2140b, 3140b is arranged in a mold and made integral with the door lid 2140, 3140. The transfer method is method of fixing the film 2140b, 3140b on the door cover 2140, 3140, made of glass or synthetic resin by heat bonding with the pressing.

FIG. 10 is a sectional view along line C-C ′ shown in FIG. 4.

As shown in FIG. 10, the door cover 140 is connected to the door frame 110. Sealing material 171 in the liquid phase can be used for the connection. The connecting structure between the door cover 140 and the door frame 110 will be described in detail below.

As described above, the door frame 110 may include an outer frame 111 and an inner frame 112.

The outer frame 111 is designed in such a way that the door cover 140 is glued to its front surface. The inner frame 112 is connected to the back side of the outer frame 111. The connection between the outer frame 111 and the inner frame 112 can be made by means of a screw connection, hook connection, gluing connection or the like.

In accordance with this drawing, it is shown that the outer frame 111 and the inner frame 112a are connected to each other by bonding together. Specifically, the fastening rib 112d is formed protruding on the inner frame 112, and the rib placing portion 111e for accommodating the fastening rib 112d is formed protruding on the rear surface of the outer frame 111, and the adhesive member 172 is filled to the rib mounting portion 111e.

On the other hand, during the connection between the outer frame 111 and the inner frame 112, the outer peripheral portion of the inner frame 112 is formed protruding on the front surface of the outer frame 111 to form the support guide 112c. The anchor rail 112c extends in the form of a loop along the periphery of the outer frame 111 to form an area for accommodating the door cover 140.

The support guide 112c may be positioned to close the side surface of the door cover 140, and the upper surface of the support guide 112c may be formed protruding to a predetermined height to form the same plane as the upper surface of the adjacent door cover 140. In accordance with the above construction, a passage between the support the guide 112c and the door lid 140 may be reduced for a simpler design.

11 is a conceptual view in which the door lid 140 and the door frame 110 are shown separately in the section “D” shown in FIG. 4.

Basically, a portion (for example, a portion on top, a concave portion, etc.) having a uniquely defined shape may be a reference point allowing adjustment of the installation position during assembly, thereby facilitating assembly. However, as shown in this embodiment, when the door lid 140 is formed in a circular shape, the portion at the top has a rounded shape, thus causing a problem in which the portion providing adjustment of the installation position during assembly is unsuitable. In particular, in the case of the present disclosure, if the door lid 140 is not connected in the exact position to the door frame 110, this may cause a problem in which the first and second light-transmitting areas 141, 142 of the door lid 140 do not correspond to the first and second door openings 110a, 111b frame 110.

To solve the above problem, as shown in FIG. 11, the door lid 140 may include a portion that will be the reference point for adjusting the mounting position when assembling with the door frame 110.

Specifically, the door lid 140 may include a first edge 140 'formed by a rounded and a second edge 140 ʺ for connecting both sides of the first edge 140'. As shown in the drawing, the door cover 140 may have a round shape in which its part is cut out in a linear shape. The second edge 140ʺ may have any shape that differs in shape from the first edge 140 ', such as a linear shape, an uneven shape, or the like.

The aforementioned support guide 112c may include a first protruding portion 112 ', extending in a rounded shape to match the first edge 140', and a second protruding portion 112cʺ, extending in a linear form to match the second edge 140ʺ.

In accordance with the above construction, the second edge 140ʺ and the second protruding portion 112cʺ may be reference points providing adjustment of the installation position during assembly of the door cover 140 and the door frame 110. In other words, when the second edge 140ʺ is positioned to correspond to the second protruding section 112cʺ, the door the cover 140 may be located in a normal position on the door frame 110, and thus, the first and second light-transmitting areas 141, 142 of the door cover 140 may be arranged to match the first and the second opening 110a, 111b of the door frame 110.

The second protruding section 112cʺ may be located at any position of the door frame 110, but the second protruding section 112cʺ may preferably be formed on the underside of the door frame 110 to prevent the user from perceiving the door 10 in a round cut shape.

Below will be described the connecting structure between the door cover 140 and the door frame 110.

FIG. 12 is a front view of the first embodiment of the door frame 110 shown in FIG. 3, and FIG. 13 is an enlarged view of the portion “E” shown in FIG. 12. FIG.

As described above, the door 10 is connected to the front surface of the outer frame 111. Sealing material 171 is used for the connection, and a groove 111d for filling the sealing material into which the sealing material 171 is filled is formed on the front surface of the outer frame 111.

A groove 111d for filling the sealing material is formed to surround the first hole 110a and the second hole 111b, respectively. For this purpose, the groove 111d for filling the sealing material may include a coupling groove 111d'3, a first groove 111d'1 and a second groove 111d'2.

The coupling groove 111d'3 is formed to extend between the first and second holes 110a, 111b. The connecting groove 111d'3 can be formed in a rectilinear form or a curved form on at least one portion thereof (for example, in a U-shape, surrounding both sides and the bottom side of the second hole 111b), as shown in the drawing.

The first groove 111d'1 is connected to both ends of the coupling groove 111d'3 and is formed to surround the periphery of the first opening 110a together with the coupling groove 111d'3. The first groove 111d'1 may extend along the inner periphery of the outer frame 111.

The second groove 111d'2 is connected to both ends of the coupling groove 111d'3 and is formed to surround the periphery of the second hole 111b together with the coupling groove 111d'3. The second groove 111d'2 may extend along the inner periphery of the outer frame 111.

The first groove 111d'1 and the second groove 111d'2 can be formed to communicate with each other at both ends of the coupling groove 111d'3.
