[0064] Furthermore, the following embodiments are provided for the purpose of providing a complete explanation to those skilled in the art, and for the sake of clarity, the shape and size of the elements in the accompanying drawings may be exaggerated.

[0065] Figure 1 A diagram illustrating the external shape of a laundry dryer according to an embodiment of the present invention is shown. Figure 2 A cross-sectional view is shown to illustrate the internal structure of a laundry dryer according to an embodiment of the present invention.

[0066] like Figure 1 and Figure 2As shown, the housing 10 forming the outer body of the laundry dryer 1 includes: a front panel 11, constituting the front of the laundry dryer 1; a rear panel 12, constituting the rear; a pair of side panels 14, constituting the sides; and an upper panel 13, constituting the top.

[0067] The front panel 11 may include: an inlet 111 configured to communicate with the roller 20 described later; and a door 112 rotatably coupled to the housing 10 to open and close the inlet 111.

[0068] A control panel 117 is located on the front panel 11.

[0069] The control panel 117 may include: an input unit 118 for receiving control commands from the user; a display unit 119 for outputting information such as control commands that the user can select; and a main control unit (not shown) for controlling the execution of the program of the laundry dryer 1.

[0070] On the other hand, the input unit 118 may include: a power supply request unit, which requests power to the laundry dryer; a process input unit, which allows the user to select a desired process from a plurality of processes; and an implementation request unit, which requests the start of the process selected by the user.

[0071] The display unit 119 may include at least one of a display panel capable of outputting text and / or graphics and a speaker capable of outputting voice signals and sound. Through the information output by the display unit 119, the user can easily grasp the status of the currently running program, the remaining time, etc.

[0072] Inside the housing 10 are: a drum 20 configured to rotate, providing space for accommodating clothes (drying items); a duct section 30 forming a flow path for resupplying air discharged from the drum 20 to the drum 20; and a heat exchange section 40 dehumidifying and heating the air flowing into the duct section 30 before resupplying it to the drum 20.

[0073] The roller 20 includes a cylindrical roller body 21 with its front open. Inside the housing 10, there may be: a first support 22 that supports the front of the roller body 21 so that it can rotate; and a second support 23 that supports the rear of the roller body 21 so that it can rotate.

[0074] The first support part 22 may include: a first fixing body 22a, fixed inside the housing 10; a roller inlet 22b, penetrating through the first fixing body 22a to connect the inlet 111 and the inside of the roller body 21; and a first support body 22c, disposed on the first fixing body 22a and inserted into the front of the roller body 21.

[0075] The first support portion 22 may further include a connecting body 22d that connects the inlet 111 and the roller inlet 22b. As shown in the figure, the connecting body 22d may have a tube shape extending from the roller inlet 22b toward the inlet 111. In addition, an air outlet 22e communicating with the pipe portion 30 may be provided in the connecting body 22d.

[0076] like Figure 2 As shown, the air outlet 22e is a channel for the internal air of the roller body 21 to move to the pipe section 30, and it can be a through hole that passes through the connecting body 22d.

[0077] The second support part 23 includes: a second fixing body 23a, which is fixed inside the housing 10; and a second support body 23b, which is disposed on the second fixing body 23a and inserted into the rear of the roller body 21.

[0078] An air inlet 23c is provided in the second support part 23. The air inlet 23c penetrates the second fixed body 23a to connect the interior of the roller body 21 and the interior of the box 10.

[0079] In this case, the duct section 30 is configured to connect the air outlet 22e and the air inlet 23c.

[0080] The cylindrical roller body 21 can be rotated by a drive unit 50 of various shapes.

[0081] For example, Figure 2 One embodiment is shown, wherein the drive unit 50 includes: a roller motor 51 fixed inside the housing 10; a pulley 52 rotated by the roller motor 51; and a belt 53 connecting the circumferential surface of the pulley 52 and the circumferential surface of the roller body 21.

[0082] In this case, the first support part 22 may be provided with a first roller R1 that supports the circumferential surface of the roller body 21 so that it can rotate, and the second support part 23 may be provided with a second roller R2 that supports the circumferential surface of the roller body 21 so that it can rotate.

[0083] However, the present invention is not limited thereto. A direct-drive mechanism in which the roller motor 51 is directly connected to the roller and rotates the roller can also be used without the aid of pulleys and belts; this approach is also within the scope of the present invention. For ease of explanation, the following description will be based on the embodiment of the drive unit 50 shown in the figures.

[0084] The duct section 30 includes: an exhaust duct 31 connected to an air outlet 22e; a supply duct 32 connected to an air inlet 23c; and a connecting duct 33 connecting the exhaust duct 31 and the supply duct 32, wherein a heat exchange section 40 is provided inside the connecting duct 33.

[0085] The heat exchange section 40 can be a variety of devices capable of sequentially dehumidifying and heating the air flowing into the duct section 30. For example, the heat exchange section 40 can be a heat pump system.

[0086] As a heat pump system, the heat exchange section 40 may include: a circulating fan 43 that moves air along the pipe section 30; a first heat exchanger (heat absorption section) 41 that performs a dehumidification function by reducing the humidity of the air flowing into the pipe section 30; and a second heat exchanger (heat generation section) 42 that is disposed inside the pipe section 30 and heats the air that has passed through the first heat exchanger 41.

[0087] The circulating fan 43 includes: an impeller 43a disposed inside the duct section 30; and an impeller motor 43b that rotates the impeller 43a. The circulating fan 43 provides flow power to the air moving along the duct section 30.

[0088] Impeller 43a can be installed at any position in exhaust pipe 31, connecting pipe 33, and supply pipe 32. Figure 2 An embodiment in which the impeller 43a is disposed in the connecting pipe 32 is shown. The present invention is not limited thereto, but for ease of explanation, the following description is based on the embodiment in which the impeller 43a is disposed in the connecting pipe 32.

[0089] The heat exchange section 40 can exchange heat with the air circulating along the pipe section 30.

[0090] The heat-absorbing part 41 and the heat-generating part 42 are located inside the connecting pipe 33 and are arranged sequentially from the exhaust pipe 31 to the supply pipe 32. They are connected to each other by the refrigerant pipe 44, which forms a refrigerant circulation path.

[0091] The heat absorption section 41 is a unit that cools the air and causes the refrigerant to evaporate by transferring the heat of the air flowing into the exhaust pipe 31 to the refrigerant.

[0092] The heating unit 42 is a unit that heats the air and condenses the refrigerant by transferring the heat of the refrigerant that has passed through the compressor 45 to the air.

[0093] The compressor 45 receives rotational force from the compressor motor 45a and compresses the refrigerant that exchanges heat with the air circulating along the pipe section 30.

[0094] In this case, the moisture contained in the air moves along the surface of the heat-absorbing part 41 as it passes through the heat-absorbing part 41 and accumulates on the bottom surface of the connecting pipe 33.

[0095] As described above, the structure of the heat exchange section 40, which includes a heat absorption section 41 and a heat generation section 42, is a structure known in the art, and therefore a detailed description of its structure is omitted.

[0096] On the other hand, in order to collect the condensate that accumulates on the bottom surface of the connecting pipe 33 from the air condensation through the heat absorption section 41, the laundry dryer 1 of the present invention is provided with a water collection section 60.

[0097] The condensate that forms in the heat absorption section 41 can be collected in the water collection section 60 once, and then collected again in the water storage section 70. As shown in the figure, the water collection section 60 can be located inside the connecting pipe 33, or it can be set up independently in a space separated from the connecting pipe 33.

[0098] The condensate collected by the water collection section 60 is supplied to the water storage section 70 through the condensate supply pipe 61. At this time, a condensate pump 62 is installed in the condensate supply pipe 61 to smoothly discharge the condensate.

[0099] The water storage section 70 has a water tank 72 that can be extended outward from one side of the front panel 11. The water tank 72 is configured to collect condensate transferred from the water collection section 60, which will be described later.

[0100] The user can remove the water storage tank 72 from the housing 10 to drain the condensate, and then reinstall it into the housing 10. Therefore, the laundry dryer of the present invention can be installed in locations without sewers or similar facilities.

[0101] More specifically, the water storage section 70 may include: a water storage tank 72, which is detachably disposed in the tank body 10 to provide space for storing water; and an inlet 72a, which penetrates the water storage tank 72 to allow water discharged from the condensate supply pipe 61 to flow into the interior of the water storage tank 72.

[0102] The water storage tank 72 can be a drawer-shaped water tank extending from the tank body 10. In this case, a water storage section mounting hole for inserting the water storage tank 72 is provided on the front panel 11 of the tank body.

[0103] Panel 71 is fixed to the front of water tank 72. Panel 71 can be detachably attached to the water storage section mounting hole to form part of front panel 11.

[0104] The panel 71 may also be provided with a groove 71a for the user to insert and hold. In this case, the panel 71 also functions as a handle for leading the water tank 72 out of the tank body or inserting it into the tank body.

[0105] The inlet 72a is configured to receive condensate discharged from the condensate nozzle 63 fixed to the housing 10. The condensate nozzle 63 can be fixed to the upper panel 13 of the housing 10 so that it is located above the inlet 72a when the water tank 72 is inserted into the housing 10.

[0106] The user can extend the water storage tank 72 from the tank body 10, and then invert or tilt the water storage tank 72 towards the inlet 72a to empty the water inside the water storage tank 72. It may also include a connecting hole 72b that extends through the upper surface of the water storage tank 72, allowing water inside the water storage tank 72 to be easily discharged through the inlet 72a.

[0107] In addition, the laundry dryer 1 of the present invention is a unit for removing foreign objects such as lint and dust generated during the drying process of laundry, and includes a first filter section F1 and a second filter section F2.

[0108] The first filter unit F1 is provided in the exhaust pipe 31 to filter foreign objects contained in the air discharged from the drum 20.

[0109] The second filter section F2 is positioned downstream of the first filter section F1 along the airflow direction to perform secondary filtration of foreign matter contained in the air that has passed through the first filter section F1. More specifically, as shown in the figure, the second filter section F2 is preferably positioned inside the connecting pipe 33 and upstream of the first heat exchanger 41. This is to prevent foreign matter contained in the air from accumulating on the first heat exchanger 41, which functions as a heat-absorbing section, and thus contaminating the first heat exchanger 41 or causing performance degradation.

[0110] The detailed structure of the first filter section F1 and the second filter section F2 can be described using any unit known in the art, therefore, a detailed description of their structure is omitted.

[0111] On the other hand, the laundry dryer 1 of the present invention further includes: a water supply unit 80, including an internal water supply unit 81 and an external water supply unit 82; and a steam unit 90, which receives water from the water supply unit 80 and generates steam.

[0112] The steam unit 90 can be configured to receive fresh, non-condensable water to generate steam. The steam unit 90 may include: a steam generator 91, a steam pipe 92, a steam nozzle 93, and a liquid receiver 94.

[0113] The steam generator 91 can receive water from the water supply unit 80 and generate steam by heating the received water. The piping structure for water flowing into the steam generator 91 and steam being emitted will be described later.

[0114] On the other hand, in this embodiment, the steam generator 91 is described as generating steam by heating a predetermined amount of water contained inside using a heater (not labeled) (hereinafter, for ease of explanation, it is referred to as "barrel heating method"), but is not limited thereto.

[0115] Steam generated in steam generator 91 can flow into steam nozzle 93, which can spray steam into the interior of drum 20.

[0116] Steam pipe 92 connects steam generator 91 and steam nozzle 93, and a flow path for steam flow is formed inside steam pipe 92. Therefore, steam generated in steam generator 91 can flow along steam pipe 92 and be discharged into the interior of drum 20 through steam nozzle 93.

[0117] At this time, the steam generated in the steam generator 91 may be condensed in the steam pipe 92 or the steam nozzle 93, resulting in condensate water flowing into the inside of the drum 20.

[0118] To address the above problems, the present invention may include a liquid reservoir 200 capable of separating condensate from steam.

[0119] A liquid receiver 200 is installed on the steam pipe 92. When the steam generated in the steam generator 91 is condensed into condensate in the steam pipe 92, the liquid receiver 200 can separate the condensate from the steam. Specifically, the liquid receiver 200 is connected to the first steam pipe 921 and the second steam pipe 922, and can separate the condensate mixed in with the steam. At this time, the condensed condensate can either flow back into the steam generator 200 or flow into the water collection section 60 (see reference 60). Figure 7 ).

[0120] The specific structure of the reservoir 200 will be explained later.

[0121] The steam unit 90 can be controlled to supply steam to the interior of the drum body 21 by receiving water through the internal water supply unit 81 and the external water supply unit 82 as needed.

[0122] The external water supply unit 82 may include: a straight-through water valve 82a, which is adjacent to or fixed to the rear panel 13; and a water supply pipe 84, which supplies water from the straight-through water valve 82a to the steam unit 90.

[0123] The direct-flow water valve 82a can be configured to connect to an external water supply source. For example, the direct-flow water valve 82a can be connected to a water supply pipe (not shown) extending to the rear of the housing. Thus, the steam unit 90 can directly receive water through the direct-flow water valve 82a.

[0124] Therefore, even if the internal water supply unit 81 is omitted or no water is stored in the internal water supply unit 81, the steam unit 90 can receive water for generating steam through the direct water valve 82a when needed.

[0125] The direct-flow water valve 82a can be directly controlled by the control unit 100.

[0126] The control unit 100 can be located in the control panel 117, but if Figure 1 As shown, in order to prevent overload of the control panel 117 and avoid increased manufacturing costs, the control unit 100 can be a separate control panel.

[0127] At this time, the control unit 100 can be arranged adjacent to the steam unit 90. The control unit 100 is provided on the side panel 14 on which the steam unit 90 is mounted, thereby shortening the length of the control lines and the like connected to the steam unit 90.

[0128] On the other hand, the steam section 90 is preferably disposed adjacent to the straight-through water valve 82a. This prevents unnecessary residual water from remaining in the straight-through water pipe 82b and allows water to be received immediately when needed.

[0129] On the other hand, the internal water supply unit 81 includes: a storage tank 810 for storing water; a supply pump 820 for receiving water from the storage tank 810 and transmitting it to the steam unit 90; a tank shell 830 for providing space to accommodate the storage tank 810 and the supply pump 820; and an internal water supply pipe 83 for connecting the supply pump 820 and the steam unit 90, and forming a flow path for water to flow inside it.

[0130] Therefore, the internal water supply unit 81 is configured to supply stored water to the steam unit. That is, the water stored in the storage tank 810 can be supplied to the steam unit 90 along the internal water supply pipe 83 by means of the operation of the supply pump 820.

Figure 4 A cross-sectional view is shown to illustrate a liquid reservoir in a laundry dryer according to an embodiment of the present invention. Figure 5 A perspective view of the base of the liquid reservoir in a laundry dryer according to an embodiment of the present invention is shown. Figure 6 A perspective view of the base of the liquid reservoir in a laundry dryer according to an embodiment of the present invention is shown from another direction.

[0132] Below, refer to Figures 3 to 6 This invention describes a liquid reservoir according to an embodiment of the present invention.

[0133] The liquid storage device 200 of the present invention is disposed on the steam pipe 92 and is supported by gripping the water supply pipe 84 of the water supply section 80, and can separate condensate from the steam flowing along the steam pipe 92.

[0134] At this time, the liquid reservoir 200 of the present invention may include: a base 210, a cover 220 and a support 230.

[0135] The base 210 can form the lower outer shell of the liquid reservoir 200 of the present invention, and a space for accommodating condensate separated from vapor can be formed inside the base 210.

[0136] Specifically, the base 210 may include: a base body 211, a condensate separation plate 212, an inlet 213, an outlet, and a cover-connecting protrusion 215.

[0137] The base body 211 can form the lower appearance of the liquid reservoir 200. As an example, the base body 211 can be formed in the shape of a box.

[0138] Specifically, a bottom surface 211a can be formed on the lower side of the base body 211 in the direction of gravity. The outer end of the bottom surface 211a can be surrounded and connected to each other by a first side surface 211b, a second side surface 211c, a third side surface 211d, and a fourth side surface 211e. That is, a sidewall composed of the first side surface 211b, the second side surface 211c, the third side surface 211d, and the fourth side surface 211e is formed at the outer end of the bottom surface 211a, thereby forming a space that can store or contain condensate.

[0139] As an example, the first side surface 211b can refer to the surface disposed in the direction of steam inflow. That is, an inlet 213 is formed on the first side surface 211b, so that steam and condensate discharged from the steam generator 91 can flow in.

[0140] Additionally, the second side surface 211c can refer to the surface disposed in the direction of steam discharge. That is, a discharge port 214 is formed on the second side surface 211c, allowing steam to be discharged toward the steam nozzle 93.

[0141] The third side 211d can refer to the surface connecting the first side 211b and the second side 211c, and a support portion 230 can be formed protruding from its outer side. On the other hand, the inner side of the third side 211d can be connected to the condensate separator plate 212.

[0142] The fourth side 211e can refer to the surface that connects the first side 211b and the second side 211c and is positioned opposite the third side 211d. On the other hand, the inner surface of the fourth side 211e can be connected to the condensate separator plate 212.

[0143] The condensate separation plate 212 is formed inside the base body 211 and can extend upward from the bottom surface 211a of the base body 211.

[0144] As an example, three condensate separator plates 212 may be formed by protruding from the bottom surface 211a. Specifically, the condensate separator plate 212 may include a first separator plate 212a and a second separator plate 212b connected to the third side surface 211d, and may include a third separator plate 212c connected to the fourth side surface 211e.

[0145] At this time, the condensate separation plate 212 can be formed at a specified angle with the third side 211d or the fourth side 211e.

[0146] As an example, the first separation plate 212a may be formed at a predetermined angle to the third side surface 211d, so that the gap between the first side surface 211b and the first separation plate 212a gradually narrows along the steam flow direction. Furthermore, the second separation plate 212a may be formed at a predetermined angle to the third side surface 211d, so that the gap between the second side surface 211c and the second separation plate 212b gradually narrows along the steam flow direction. On the other hand, the third separation plate 212c may be formed perpendicular to the fourth side surface 211e.

[0147] With this structure, the cross-sectional area of ​​the flow path through which the steam flowing in via inlet 213 passes can be continuously changed. Therefore, the steam flow rate can be altered, adiabatic expansion or compression can be generated, and the separation efficiency of condensate contained in the steam can be improved.

[0148] The inlet 213 extends outward from the outer side of the base body 211 and is inserted into the first steam pipe 921, so that the steam generated in the steam generator 91 can flow in.

[0149] As an example, the inlet 213 can be formed by protruding and extending in a cylindrical shape on the first side 211b, and a steam inflow path 213a is formed inside it so that the steam generated in the steam generator 91 can flow into the space inside the base body 211.

[0150] At this time, a portion of the inner circumferential surface of the inlet 213 can be positioned lower than the bottom surface 211a in the direction of gravity. Specifically, a portion of the steam inflow path 213a formed inside the inlet 213 can be formed at a position lower than the bottom surface 211a.

[0151] Therefore, gaseous steam can flow into the interior space of the base body 211 via steam inflow path 213a. On the other hand, condensate that has separated from the steam and is captured (or condensed) in the interior space of the base body 211 can flow back to the steam generator 91 via steam inflow path 213a under the action of gravity and be recycled back to the steam generator 91.

[0152] The outlet 214 can extend from the other side of the base body 211 and be inserted into the second steam pipe 922, so that the steam separated from the condensate can be discharged to the steam nozzle 93.

[0153] As an example, the outlet 214 can be formed by protruding and extending in a cylindrical shape on the second side 211c, and a steam discharge flow path 214a is formed inside it so that the steam from which the condensate is separated can be discharged toward the steam nozzle 93.

[0154] At this time, the outlet 214 can be configured at a higher position than the inlet 213. Specifically, the outlet 214 can be configured in the direction of gravity at a position higher than the inlet 213 with the bottom surface 211a as a reference, and the steam discharge flow path 214a can be formed at a position higher than the steam inlet flow path 213a.

[0155] Therefore, gaseous steam can be discharged through steam discharge path 214a. In contrast, condensate cannot pass through steam discharge path 214a, but is instead captured by gravity and trapped in the internal space of the base body 211. Therefore, according to this structure, the discharge of condensate towards the steam nozzle 93 can be blocked.

[0156] On the other hand, the cover-fitting protrusion 215 can protrude from the outer side of the sidewall of the base body 211 and engage with the cover 220. As an example, the cover-fitting protrusion 215 can protrude from the first side 211b, the second side 211c, the third side 211d, and the fourth side 211e respectively. According to the embodiment, it can protrude from the first side 211b and the second side 211c, or it can protrude from the third side 211d and the fourth side 211e. In this embodiment, the cover-fitting protrusion 215 may include an inclined surface to engage with the cover 220 via a hook.

[0157] On the other hand, the cover 220 of the present invention can be combined with the base 210 to form a flow path for steam flow.

[0158] The cover 220 can form the upper outer shell of the liquid reservoir 200 of the present invention.

[0159] The cover 220 may include a cover body 221 and a connecting portion 222. Specifically, the cover 220 may include: a cover body 221 that covers the base 210 to form a flow path for steam flow; and a connecting portion 222 that extends from the side wall of the cover body 221 and has a hook receiving hole 222a for receiving the cover connecting protrusion 215.

[0160] As an example, the cover body 221 can be formed into a box shape that opens downwards, and its width and length can be greater than the width and length of the base 210, so that the base 210 can be inserted into the interior of the cover 220. In this case, the connecting portion 222 can be formed by extending downwards from the front end of the side wall of the cover body 221. On the other hand, the hook receiving hole 222a can be formed into a quadrilateral hole shape to accommodate the cover connecting protrusion 215.

[0161] With this structure, the cover 220 can be combined with the base 210 to form a space for steam flow and prevent steam from leaking to the outside.

[0162] In particular, in this invention, the interior of the cover 220 may also include a sealing component to seal the space between the cover 220 and the base 210, thereby preventing external leakage of steam.

[0163] The support portion 230 of the present invention can be formed by protruding from the outer side of the base 210 to grip the outer peripheral surface of the water supply pipe 84. As an example, the support portion 230 can be formed by protruding from the outer side of the third side 211d and can be configured such that the water supply pipe 84 is inserted into the support portion 230 and supports each other.

[0164] The support portion 230 may include support plates 231 and 232 that contact the outer peripheral surface of the water supply pipe 84. Specifically, the support portion 230 may include: an upper support plate 231 that contacts the upper side of the outer peripheral surface of the water supply pipe 84; and a lower support plate 232 that contacts the lower side of the outer peripheral surface of the water supply pipe 84.

[0165] As an example, two upper support plates 231 may be formed parallel to each other on the third side surface 211d, and may include an upper contact surface 231a formed as a curved surface to form a surface contact with the upper side of the outer peripheral surface of the water supply pipe 84. In this case, the curvature of the upper contact surface 231a may be formed corresponding to the curvature of the outer peripheral surface of the water supply pipe 84.

[0166] Additionally, the upper support plate 231 may also include a protrusion 231b, which extends protrudingly from the third side surface 211d and connects to the upper contact surface 231a. In this case, the protrusion 231b can extend protrudingly from the third side surface 211d in a vertical direction, and two protrusions 231b can form a pair. The upper contact surface 231a can be disposed between the pair of protrusions 231b and can connect with the pair of protrusions 231b to each other. Furthermore, the upper contact surface 231a can extend from the outer end of the protrusion 231b in a curved shape.

[0167] On the other hand, the upper support plate 231 may also include an upper guide surface 231c, which is formed by bending and extending upward from the outer end of the upper contact surface 231a to guide the assembly of the water supply pipe 84.

[0168] According to this structure, when the water supply pipe 84 is inserted from a direction perpendicular to the third side 211d, the upper support plate 231 elastically deforms like a cantilever, thereby allowing the water supply pipe 84 to be inserted and engaged.

[0169] The lower support plate 232 may include a lower contact surface 232a formed as a curved surface to form a surface contact with the lower side of the outer peripheral surface of the water supply pipe 84. In this case, the curvature of the lower contact surface 232a may be formed corresponding to the curvature of the outer peripheral surface of the water supply pipe 84.

[0170] Additionally, the lower support plate 232 may further include a lower support portion 232b, which extends from the lower side surface and the third side surface 211d of the bottom surface 211a and connects with the lower contact surface 232a to support it. In this case, the lower support portion 232b can extend from the bottom surface 211a and the third side surface 211d in a vertical direction, and two lower support portions 232b can form a pair. The lower contact surface 232a can be disposed between the pair of lower support portions 232b and can be connected to the pair of lower support portions 232b. Furthermore, the lower contact surface 232a can extend from the outer end of the lower support portion 232b in a curved shape.

[0171] On the other hand, the lower support plate 232 may also include a lower guide surface 232c, which is formed by bending and extending downward from the outer end of the lower contact surface 232a to guide the assembly of the water supply pipe 84.

[0172] According to this structure, when the water supply pipe 84 is inserted from a direction perpendicular to the third side 211d, the lower support plate 232 elastically deforms like a cantilever, thereby allowing the water supply pipe 84 to be inserted and engaged.

[0173] As a result, the water supply pipe 84 can be inserted and connected between the upper support plate 231 and the lower support plate 232, and the upper contact surface 231a and the lower contact surface 232b can surround the outer peripheral surface of the water supply pipe 84. Therefore, with the help of the structure of the support part 230, the liquid reservoir 200 of the present invention can be supported by the water supply pipe 84, which can prevent it from being detached from its installed position due to external impacts, etc., and can maintain the configuration of the steam piping 92 and the water supply pipe 84.

[0174] on the other hand, Figure 7 A diagram is shown illustrating the state in which a liquid reservoir is installed in a laundry dryer according to an embodiment of the present invention. Figure 8 A diagram is shown illustrating another state in which a liquid reservoir is installed in a laundry dryer according to an embodiment of the present invention. Figure 9 A diagram is shown illustrating another state in which a liquid reservoir is installed in a laundry dryer according to an embodiment of the present invention.

[0175] Below, refer to Figures 1 to 3 , Figures 7 to 9 This invention describes a method for installing a liquid reservoir 200 in a laundry dryer 1 according to an embodiment of the present invention, and the location of the liquid reservoir 200.

[0176] First, the laundry dryer 1 of the present invention may further include an upper frame 24, disposed on the upper side of the drum 20 and supporting the housing 10. In this case, according to the embodiment, the upper frame 24 may be combined with the first support portion 22 and the second support portion 23, or it may be combined with the front panel 11 and the back panel 12. Therefore, the upper frame 24 can serve to support the laundry dryer 1.

[0177] In addition, in the laundry dryer 1 of the present invention, the steam piping 92 may include: a first steam piping 921, connecting the steam generator 91 and the liquid reservoir 200; and a second steam piping 922, connecting the liquid reservoir 200 and the steam nozzle 93.

[0178] At this time, the steam unit 90 of the present invention receives water as needed through the internal water supply unit 81 and the external water supply unit 82 and supplies steam to the interior of the drum body 21. Therefore, the laundry dryer 1 of the present invention may include: an internal water supply pipe 83 for supplying water to the internal water supply unit 81; and a connector 85 for connecting to the water supply pipe 84 for supplying water to the external water supply unit 82. As an example, the connector 85 may be a T-shaped connector.

[0179] In addition, the laundry dryer 1 of the present invention may also include a check valve 86 to prevent backflow of water flowing to the steam generator 91.

[0180] Reference Figure 7A water supply pipe 84 and a steam pipe 92 can be arranged on the upper side of the upper frame 24. The water supply pipe 84 and the internal water supply pipe 83 can be connected to each other via a connector 85. At this time, the first steam pipe 921 is arranged on the upper side of the connector 85 and can be supported by the upper side of the connector 85 depending on the installation conditions. In addition, one end of the second steam pipe 922 is connected to the liquid reservoir 200, and the other end is connected to the steam nozzle 93. Depending on the positional relationship between the liquid reservoir 200 and the steam nozzle 93, the middle of the second steam pipe 922 can be arranged in a bent state.

[0181] In this configuration, two check valves 86 can be installed on the water supply pipe 84 to prevent backflow. That is, the water supply pipe 84 can be composed of three separate pipes connected to each other by check valves 86. In this case, the reservoir 200 needs to be connected to the first steam pipe 921 and the second steam pipe 922 and held in place by the water supply pipe 84 for support. Under such installation conditions, the reservoir 200 is most stable when it is held in place by the water supply pipe 84 between the two check valves 86. Considering the configuration and mutual interference of the water supply pipe 84, the internal water supply pipe 83, and the steam pipe 92, the reservoir 200 is preferably positioned on the upper side of the upper frame 24.

[0182] on the other hand, Figure 8 Another installation condition of the invention is shown. Under this installation condition, a check valve 86 is installed in the water supply pipe 84, and the check valve is also internally integrated into the connector 85. That is, the water supply pipe 84 can be constructed from two separate pipes connected to each other via the check valve 86. Under such installation conditions, with... Figure 7 Compared to the water supply pipe 84 shown, the water supply pipe 84 between the check valve 86 and the connector 85 can have a relatively longer length, thereby allowing for a larger range of space to be configured for the reservoir 200. Therefore, the reservoir 200 can be configured not only on the upper side of the upper frame 24, but also in the space between the internal water supply pipe 83 and the upper frame 24.

[0183] on the other hand, Figure 9 Another installation condition of the invention is shown. In this installation condition, the internal water supply pipe 83 and connector 85 are not present. Furthermore, two check valves 86 are provided on the water supply pipe 84. Under this installation condition, the two check valves 86 can be arranged on the outside (across) of the upper frame 24, with reference to the steam generator 91. Therefore, with... Figure 7 and Figure 8In comparison, the water supply pipe 84 between the check valve 86 and the steam generator 91 can have the longest length, thereby maximizing the space available for configurable reservoir 200. Therefore, reservoir 200 can be configured not only on the upper side of upper frame 24, but also between steam generator 91 and upper frame 24.

[0184] on the other hand, Figure 10 A perspective view is shown illustrating the structure of the liquid reservoir in a laundry dryer according to a second embodiment of the present invention. Figure 11 A perspective view of the base of the liquid reservoir in a laundry dryer according to a second embodiment of the present invention is shown. Figure 12 A perspective view of the base of the liquid reservoir in the laundry dryer of the second embodiment of the present invention, viewed from another direction, is shown. Figure 13 A bottom view of the base of the liquid reservoir in a laundry dryer according to a second embodiment of the present invention is shown. Figure 14 A side view of the base of the liquid reservoir in a laundry dryer according to a second embodiment of the present invention is shown. Figure 15 A cross-sectional view is shown illustrating the installation of the liquid reservoir in a laundry dryer according to a second embodiment of the present invention.

[0185] In this embodiment, to avoid repetitive description, the structure and effects are the same as those of the reservoir 200 of an embodiment of the present invention, except for the parts specifically mentioned, and therefore the description thereof can be continued.

[0186] In this invention, the height of the inlet 213 of the liquid reservoir 200 needs to be higher than the steam outlet 91a of the steam generator 91 to increase the gas-liquid separation effect. That is, gaseous steam tends to rise along the first steam pipe 921, and the condensate separated from the steam tends to flow downwards in the direction of gravity under the action of gravity. Therefore, if the height of the inlet 213 is higher than the height of the steam outlet 91a that generates steam, the steam flow efficiency can be improved, and the separation efficiency and recovery efficiency of the condensate can also be improved.

[0187] However, the liquid reservoir 200 of one embodiment of the present invention has the limitation that it cannot maintain the height of the inlet 213 above the height of the steam outlet 91a.

[0188] To address this problem, the reservoir 200 of the second embodiment of the present invention is characterized by the addition of a structure for maintaining the height of the inlet 213 above the height of the steam outlet 91a. This will be explained later.

[0189] Reference Figures 10 to 15In this embodiment, the reservoir 200 may further include a fixing part 240, which extends downward from the bottom surface 211a of the base 210 to form and support the base 210, and is combined with the upper frame 24.

[0190] Specifically, the fixing part 240 may include: a height adjustment end 241 extending downward from the bottom surface 211a; and a fixing plate 242 protruding from the side wall surface of the height adjustment end 241.

[0191] In order to guide the flow direction of steam and condensate, the height adjustment end 241 extends into a columnar shape with a specified height h, thereby enabling the height of the base 210 to be adjusted.

[0192] As an example, the height adjustment end 241 can be formed by extending downward from the lower side of the bottom surface 211a in the form of a quadrilateral prism. In this case, the height adjustment end 241 can be formed as a hollow prism to reduce the overall weight, or it can be formed with a panel in the form of a window lattice to support the hollow interior.

[0193] The fixing plate 242 can be formed by protruding from the side wall of the height adjustment end 241. In addition, the fixing plate 242 can be formed with fixing holes 242a for fixing and connecting.

[0194] As an example, the fixing plate 242 can be formed by protruding from the outer side of the surface that forms a continuous surface with the fourth side surface 211e in the height adjustment end 241. It can be formed such that its width gradually narrows as it protrudes from the outer side of the height adjustment end 241, and it can be formed into a plate shape with a predetermined thickness. In this case, the lower side of the fixing plate 242 can form the same plane as the lower end of the height adjustment end 241. On the other hand, the fixing plate 242 can also be further formed with a quadrilateral hole located vertically below the cover-joining protrusion 215 for ease of manufacturing.

[0195] With this structure, in this embodiment, after the fixing plate 242 is placed on the upper frame 24 and the fixing hole 242a is positioned above the bolt hole 24a of the upper frame 24, the liquid reservoir 200 can be fixed to the upper frame 24 using bolts or other fixing components. Furthermore, by utilizing the height of the height adjustment end 241, the height of the inlet 213 can be maintained above the height of the steam outlet 91a.

[0196] On the other hand, the reservoir 200 of this embodiment may also include: an assembly hook 250, which extends from the lower side of the support portion 230 and is engaged with the upper frame 24 and supported.

[0197] Specifically, the assembly hook 250 may include: a column portion 251, which protrudes downward from the outer side (lower side) of the lower contact surface 232a in a column shape; and an engaging portion 252, which extends and bends from the column portion 251.

[0198] As an example, the column portion 251 can be a quadrilateral column extending in a direction parallel to the axial direction (which can be the flow path direction) of the inlet 213 or outlet 214, and the ribs used to strengthen the quadrilateral column can be formed by protruding from the surface in the direction of the third side 211d of the quadrilateral column. That is, the column portion 251 can be formed into a polygonal prism shape with a cross-section approximately T-shaped.

[0199] On the other hand, the engaging portion 252 can be formed by bending and extending outward from the lower end of the column portion 251 (in the opposite direction to the direction in which the fixing portion 240 is disposed).

[0200] On the other hand, in this embodiment, a quadrilateral hole 232aa can also be formed on the lower contact surface 232a to facilitate the manufacture and assembly of the hook 250.

[0201] With this structure, in this embodiment, if the engaging part 252 is inserted into the assembly hole 24b of the upper frame 24, and the reservoir 200 is rotated around the point where the upper frame 24 and the engaging part 252 contact each other, the positions of the fixing hole 242 and the bolt hole 24a can be aligned, thereby improving assemblability. Furthermore, when the fixing part 240 is fixedly engaged with the upper frame 24, the engaging part 252 acts as a stop to prevent the reservoir 200 from rotating or detaching from the upper frame 24.

[0202] Figure 16 A diagram is shown illustrating the state in which a liquid reservoir is installed in a laundry dryer according to a second embodiment of the present invention.

[0203] Reference Figure 16 A water supply pipe 84 and a steam pipe 92 can be arranged on the upper side of the upper frame 24. The water supply pipe 84 and the internal water supply pipe 83 can be connected to each other via a connector 85. At this time, the first steam pipe 921 is arranged on the upper side of the connector 85 and can be supported by the upper side of the connector 85 depending on the installation conditions. In addition, one end of the second steam pipe 922 is connected to the liquid reservoir 200, and the other end is connected to the steam nozzle 93. Depending on the positional relationship between the liquid reservoir 200 and the steam nozzle 93, the middle of the second steam pipe 922 can be arranged in a bent state.

[0204] In this configuration, two check valves 86 can be installed on the water supply pipe 84 to prevent backflow. That is, the water supply pipe 84 can be composed of three separate pipes connected to each other by the check valves 86. At this time, the reservoir 200 needs to be connected to the first steam pipe 921 and the second steam pipe 922 and held in place by the water supply pipe 84 for support. Under such installation conditions, the support 230 engages the water supply pipe 84 located between the two check valves 86, and the engaging part 252 is inserted into the upper frame 24, and then the fixing plate 242 is fixedly attached to the upper frame 24. Finally, by connecting the first steam pipe 921 and the second steam pipe 922 to the reservoir 200, the reservoir can be easily installed.

[0205] Therefore, according to this embodiment, the installability of the liquid reservoir 200 can be improved. Furthermore, without a special fixing process, the height of the inlet 213 can be maintained above the height of the steam outlet 91a, resulting in improved gas-liquid separation performance and thus preventing condensate from flowing into the interior of the drum 20.

[0206] on the other hand, Figure 17 A perspective view is shown illustrating the structure of the liquid reservoir in a laundry dryer according to a third embodiment of the present invention. Figure 18 It shows Figure 17 An exploded 3D diagram.

[0207] The liquid reservoir 1200 of the present invention is disposed on the steam pipe 92 and is supported by gripping the water supply pipe 84 of the water supply section 80, and can separate condensate from the steam flowing along the steam pipe 92.

[0208] At this time, the liquid reservoir 1200 of the present invention may include: a base 1210, a cover 1220 and a support portion 1230.

[0209] The base 1210 can form the lower outer shell of the liquid reservoir 1200 of the present invention, and a space for accommodating condensate separated from vapor can be formed inside the base 1210.

[0210] Specifically, the base 1210 may include a base body 1211 and a condensate separation plate 1212.

[0211] The base body 1211 can form the lower appearance of the reservoir 1200. As an example, the base body 1211 can be formed in the shape of a box.

[0212] Specifically, a bottom surface 1211a can be formed on the lower side of the base body 1211 in the direction of gravity. The outer end of the bottom surface 1211a can be surrounded and connected to each other by a first side surface 1211b, a second side surface 1211c, a third side surface 1211d, and a fourth side surface 1211e. That is, a sidewall composed of the first side surface 1211b, the second side surface 1211c, the third side surface 1211d, and the fourth side surface 1211e is formed at the outer end of the bottom surface 1211a, thereby forming a space that can store or contain condensate.

[0213] As an example, the first side 1211b can refer to the surface arranged in the direction of steam inflow.

[0214] Additionally, the second side 1211c can refer to the surface disposed in the direction of steam discharge.

[0215] The third side 1211d can refer to the surface connecting the first side 1211b and the second side 1211c, and a support portion 1230 can be formed protruding from its outer side.

[0216] The fourth side 211e may refer to the side that connects the first side 1211b and the second side 1211c and is positioned facing the third side 1211d.

[0217] The condensate separation plate 1212 is formed inside the base body 1211 and can extend upward from the bottom surface 1211a of the base body 1211.

[0218] As an example, the condensate separator plate 1212 can be formed in three ways by protruding from the bottom surface 1211a.

[0219] Specifically, the condensate separator 1212 may include a first separator 1212a, which is formed at a predetermined angle to the side wall of the base body 1211 to guide the flow of steam generated in the steam generator 91. As an example, the first separator 1212a may be positioned close to the first side surface 1211b and may be positioned corresponding to the position of the inlet 223 of the cover 220, which will be described later.

[0220] Additionally, the condensate separator 1212 may also include a second separator 1212b, which is formed at a predetermined angle to the side wall of the base body 1211 to guide the flow of steam discharged towards the steam nozzle 93. As an example, the second separator 1212b may be positioned close to the second side surface 1211c and may be positioned corresponding to the position of the discharge port 1224 of the cover 1220 described later.

[0221] Furthermore, the condensate separator 1212 may also include a third separator 1212c, disposed between the first separator 1212a and the second separator 1212b, and formed into a curved surface. As an example, the third separator 1212c may be disposed facing the third side surface 1211d, and when viewed from the third side surface 1211d, it may form a concave curved surface.

[0222] With this structure, the cross-sectional area of ​​the flow path through which the incoming steam passes can be continuously changed. Therefore, the steam velocity can be altered, adiabatic expansion or compression can be generated, and the separation efficiency of condensate contained in the steam can be improved.

[0223] A hook receiving hole 1213 for accommodating the cover-connecting protrusion 1222 (described later) can be formed on the side wall of the base body 1211.

[0224] As an example, the hook receiving hole 1213 can be formed on the first side 1211b, the second side 1211c, the third side 1211d and the fourth side 1211e, and can be formed in the shape of a quadrilateral hole to receive the cover connecting protrusion 1222.

[0225] On the other hand, the cover 1220 of the present invention can be combined with the base 1210 to form a flow path for steam flow.

[0226] The cover 1220 can constitute the upper outer shell of the reservoir 1200 of the present invention.

[0227] The cover 1220 may include: a cover body 1221, a cover connecting protrusion 1222, an inlet 1223, and an outlet 1224.

[0228] The cover body 1221 can cover the base 1210 and form a flow path for steam flow. Specifically, the cover body 1221 may include: a cover surface 1221a, covering the base 1210; and a sidewall, surrounding the outer contour of the cover surface 1221a. In this case, the sidewall may include: a steam inflow surface 1221b, forming an inlet 1223; a steam outlet surface 1221c, forming an outlet 1224; a first connecting surface 1221d, connecting the steam inflow surface 1221b and the steam outlet surface 1221c; and a second connecting surface 1221e, formed at a position facing the first connecting surface 1221d.

[0229] As an example, the cover body 1221 can be formed into a box shape that opens downwards, and its width and length can be smaller than the width and length of the base 1210 so that it can be inserted into the interior of the base 1210.

[0230] On the other hand, the cover-joining protrusion 1222 can protrude from the outer side of the sidewall of the cover body 1221 and join with the base 1210. As an example, the cover-joining protrusion 1222 can protrude from the outer side of the steam inflow surface 1221b, the steam outflow surface 1221c, the first connecting surface 1221d, and the second connecting surface 1221e. In this case, the cover-joining protrusion 1222 is preferably formed from at least two or more surfaces.

[0231] In this embodiment, the cover engagement protrusion 1222 may include an inclined surface to engage with the base 1210 via a hook.

[0232] With this structure, the cover 1220 can be combined with the base 1210 to form a space for steam flow and prevent steam from leaking to the outside.

[0233] In particular, in this invention, the interior of the base 1210 may also include a sealing component to seal the space between the cover 1220 and the base 1210, thereby preventing external leakage of steam.

[0234] The inlet 1223 extends outward from the outer side of the cover body 1221 and is inserted into the first steam pipe 921, so that the steam generated in the steam generator 91 can flow in.

[0235] As an example, the inlet 1223 can be formed by protruding and extending in a cylindrical shape on the first side 211b, and a steam inflow path is formed inside it so that the steam generated in the steam generator 91 can flow into the space inside the base body 211.

[0236] At this time, the height of the inlet 1223 is preferably configured to be higher than the height of the steam outlet 91a. That is, in this embodiment, by making the height of the base 1210 and the cover 1220 higher than a predetermined height, the height of the inlet 1223 can be made higher than the height of the steam outlet 91a.

[0237] With this structure, the gas-liquid separation efficiency of the reservoir 1200 in this embodiment can be improved.

[0238] The outlet 1224 can be formed by protruding from the other side of the cover body 1221 and inserted into the second steam pipe 922, so that the steam separated from the condensate can be discharged to the steam nozzle 93.

[0239] As an example, the outlet 1224 can be formed by protruding and extending in a cylindrical shape on the second side 211c, and a steam discharge flow path is formed inside it so that the steam separated from the condensate can be discharged to the steam nozzle 93.

[0240] At this point, the outlet 1224 can be configured at a higher position than the inlet 1223.

[0241] Therefore, gaseous steam can be discharged through the steam discharge path. In contrast, condensate cannot pass through the steam discharge path and, under the influence of gravity, can be captured and collected in the internal space of the base body 1211. Therefore, according to this structure, the discharge of condensate to the steam nozzle 93 can be blocked.

[0242] In this embodiment, the support portion 1230 can be formed by protruding from the outer side of the base 1210 to grip the outer peripheral surface of the water supply pipe 84. As an example, the support portion 1230 can be formed by protruding from the outer side of the third side 1211d, and can be configured such that the water supply pipe 84 is inserted into the support portion 1230 and supports each other.

[0243] The support portion 1230 may include: a lower support plate 1232, which extends and protrudes from the outer side of the base body 1211; and an upper support plate 1231, which protrudes from the lower support plate 1232 and surrounds the upper outer peripheral surface of the water supply pipe 84.

[0244] As an example, the lower support plate 1232 can protrude from the outer side of the third side 1211d in a plate shape to form 1232a, and a quadrilateral hole 1232b can be formed inside it corresponding to the position of the upper support plate 1231. The lower side of the lower support plate 1232 can be formed on the same plane as the lower side of the bottom surface 1211a.

[0245] According to this structure, the lower support plate 1232 can be placed together with the bottom surface 1211a on the upper frame 24.

[0246] The upper support plate 1231 can be formed by protruding from the lower support plate 1232 and may include a curved surface to surround the upper outer peripheral surface of the water supply pipe 84.

[0247] As an example, the upper support plate 1231 may include a vertical protrusion 1232a extending upward from the lower support plate 1232, and may include a hook portion 1232b extending from the vertical protrusion 1232a in a curved shape similar to a hook or latch, for suspension and support on the water supply pipe 84. In this case, the curvature of the hook portion 1232b may correspond to the curvature of the outer peripheral surface of the water supply pipe 84. Furthermore, the upper support plate 1231 may have a plurality of protruding ribs to increase the bonding force with the water supply pipe 84.

[0248] According to this structure, the upper support plate 231 can support each other with the water supply pipe 84.

[0249] As a result, the water supply pipe 84 can be inserted between the upper support plate 1231 and the lower support plate 1232. Therefore, with the help of the support part 1230, the liquid reservoir 1200 of this embodiment can be supported by the water supply pipe 84, which can prevent it from being detached from its installed position due to external impacts, etc., and can maintain the configuration of the steam piping 92 and the water supply pipe 84.

[0250] In this embodiment, the fixing part 1240 can be formed by protruding from the outer side of the base 1210 and can be formed with fixing holes for fixing and connecting.

[0251] As an example, the fixing part 1240 can be formed by protruding from the fourth side surface 1211e, and can be formed in a shape where its width gradually narrows as it protrudes from the fourth side surface 1211e, and can be formed in the shape of a plate with a specified thickness. In this case, the lower side surface of the fixing part 1240 can form the same plane as the lower side surface of the bottom surface 1211a.

[0252] That is, the lower support plate 1232, the bottom surface 1211a and the lower side surface of the fixing part 1240 form the same plane, so that they can be stably placed on the upper frame 24.

[0253] With this structure, in this embodiment, after the fixing part 1240 is placed above the upper frame 24 and the fixing hole is arranged above the bolt hole 24a of the upper frame 24, the liquid reservoir 1200 can be fixed to the upper frame 24 using bolts or other fixing components.

[0254] Figure 19 A diagram is shown illustrating the state in which a liquid reservoir is installed in a laundry dryer according to a third embodiment of the present invention.

[0255] Reference Figure 19 A water supply pipe 84 and a steam pipe 92 can be arranged on the upper side of the upper frame 24. The water supply pipe 84 and the internal water supply pipe 83 can be connected to each other via a connector 85. At this time, the first steam pipe 921 is arranged on the upper side of the connector 85 and can be supported by the upper side of the connector 85 depending on the installation conditions. In addition, one end of the second steam pipe 922 is connected to the liquid reservoir 1200, and the other end is connected to the steam nozzle 93. Depending on the positional relationship between the liquid reservoir 1200 and the steam nozzle 93, the middle of the second steam pipe 922 can be arranged in a bent state.

[0256] In this configuration, two check valves 86 can be installed on the water supply pipe 84 to prevent backflow. That is, the water supply pipe 84 can be composed of three separate pipes connected to each other by check valves 86. In this case, the reservoir 1200 needs to be connected to the first steam pipe 921 and the second steam pipe 922 and supported by the water supply pipe 84. Under such installation conditions, the reservoir 1200 is most stable when it is supported by the water supply pipe 84 located between the two check valves 86. Considering the configuration and mutual interference of the water supply pipe 84, the internal water supply pipe 83, and the steam pipe 92, the reservoir 1200 is preferably located on the upper side of the upper frame 24.

[0257] Therefore, according to this embodiment, the liquid reservoir 1200 can be installed more easily by means of the support portion 1230 and the fixing portion 1240. In addition, by forming the inlet 1223 in the cover 1220, the height of the inlet 1223 can be kept higher than the height of the steam outlet 91a, which improves the gas-liquid separation performance and prevents condensate from flowing into the interior of the drum 20.

[0258] The above description, through specific embodiments of the present invention, is only for illustrating the present invention. The present invention is not limited thereto, and obviously, the present invention can be modified or improved by those skilled in the art.

[0259] Simple variations or modifications of this invention are all within the scope of this invention, and the specific scope of protection of this invention will be further clarified by the scope of the appended claims.
