Field of the Invention The present invention relates to a top loading type washing machine. For example, the invention relates to a top-loading type washing machine having a 10 detergent input device installed at a control panel. 2. Background of Invention Generally, a washing machine serves to remove all kinds of foreign materials attached to laundry such as clothes and bedclothes by using a softening 15 operation of detergent, a friction operation of a water current when a pulsator rotates, an impact applied to laundry from the pulsator, etc. Among various types of washing machines, a top-loading type washing machine configured to input laundry from an upper side, comprises: a cabinet for forming appearance; a tub received in the cabinet; a basket received in the tub, 20 and rotated at the time of a washing or dehydrating process; a pulsator rotatably installed at a bottom surface of the tub; a motor for rotating the pulsator and the basket; and a clutch for determining a transmission direction of a driving force of the motor so that only the pulsator rotates at the time of a washing process, and both the basket and the pulsator rotate at the time of a dehydrating process. A top cover is mounted above the cabinet. A plurality of manipulating 5 buttons for manipulating washing processes, and a control panel for displaying a manipulated state are provided at a rear upper side of the top cover. A lid is installed at a central portion of the top cover so as to introduce or draw laundry into or out of the basket by being opened and closed . A valve assembly to which a water supply pipe for supplying water is 1o connected is installed at a rear surface of the control panel. A detergent input device for supplying detergent to the basket is installed at an inner lower side of the top cover. The detergent input device is connected to the valve assembly by the hose, and thus receives washing water from the water supply pipe. is Generally, as shown in FIG. 5 disclosed in Korean Registration Patent No. 10-0303532, the detergent input device includes a detergent casing installed at an inner side of the top cover, and opened so as to be communicated with the water supply pipe; and a detergent container received in the detergent casing so as to be pulled out of the detergent casing in a drawing manner, for supplying liquid 20 detergent into the basket after dissolving powder detergent with temporarily receiving washing water supplied from the water supply pipe. However, the conventional detergent input device has the following problems. First, for detergent input, a user puts his hand into the cabinet after 25 opening the lid. Then, the user withdraws the detergent container from the 2 C \NRPonblDCCEXt II l909_LDOC-6/I 2010 -3 detergent casing by backward pulling the detergent container out of the detergent casing. Then, the user inputs a certain amount of detergent into the withdrawn detergent container, and then forwardly pushes the detergent container thus to mount at the detergent casing. 5 The entire process for detergent input is complicated and difficult. Also, there is a difficulty in putting a precise amount of detergent into the detergent container inside the dark cabinet. Furthermore, when the top cover is formed of steel, an additional coupling opening to install the detergent casing has to be formed at an inner side of the top 10 cover. As a result, the entire appearance may be degraded. It is generally desirable to overcome or ameliorate one or more of the above-described difficulties, or to at least provide a useful alternative. SUMMARY OF THE INVENTION 15 In accordance with one aspect of the invention, there is provided a top loading type washing machine, comprising: a cabinet; a tub vertically and rotatably installed in the cabinet; a top cover for covering an upper portion of the cabinet; 20 a lid for opening and closing installed above the top cover; a control panel installed above the top cover to protrude from the top cover; and a detergent input device installed at the control panel not inside the top C:\NRPortbKlDCC\EXJ1\i lB0l9 I.DOC-6/)K/2010 -4 cover so that detergent may be filled in the detergent input device with the lid closed. Preferred embodiments of the present invention provide a top-loading type 5 washing machine having a detergent input device capable of simplifying detergent input processes. Preferred embodiments of the present invention provide a top-loading type washing machine capable of preventing appearance degradation even when a top cover is formed of steel, by installing a detergent input device at a position rather 10 than inside of the top cover.

Referring to FIGS. 1 and 2, a top-loading type washing machine 100 comprises: a cabinet 110 for forming appearance; a tub 120 received in the cabinet 110, for containing washing water therein; a basket 130 received in the tub 10 120, rotated at the time of a washing or dehydrating process, and composed of an outer wall 132 and an inner wall 131; a pulsator 160 rotatably installed at a bottom surface of the inner wall 131, for stirring laundry; and a driving unit 170 for simultaneously or individually driving the basket 130 and the pulsator 160. The basket 130 is composed of an outer wall 132 that forms appearance, 15 and an inner wall 131 disposed inside the outer wall 132 with a certain gap therebetween and having a receiving space for receiving laundry. The outer wall 132 and the inner wall 131 are provided with drain holes 132a and 131a, respectively, through which washing water contained in the tub 120 is introduced into or discharged out of the basket 130. 20 A top cover 111 is installed above the cabinet 110. A lid 112 for opening and closing the basket 130 is installed above the top cover 111. A detergent input space 111a for inputting detergent is formed at a front side of the top cover 111. Detergent contained in the detergent input device 111a is mixed with washing water supplied through a valve assembly 220 and a supply pipe (not 25 shown), and then is supplied into the basket 130 via the detergent input space 6 111a. A control panel 200 is installed at a rear upper side of the top cover 111, controls the operation of the washing machine 100, and displays an operational state. To this end, a control box (C) consisting of a microcomputer and 5 components is mounted in the control panel 100. A valve assembly 220 is installed on a rear surface of the control panel 200, which includes a cool water valve 221 for supplying cool water and a warm water valve 22 for supplying warm water. A receiving unit 210 is formed at the control panel 200, and a detergent to input device 300 is inserted into the receiving unit 210. Since the detergent input device 300 is installed at the control panel 200, detergent input processes need not be performed inside the dark cabinet 110 thus to be simplified. Furthermore, since the detergent input device 300 is installed at the control panel 200 not at the top cover 111, even if the top cover 111 is formed of steel, the top cover 111 does 15 not have degraded appearance. Referring to FIGS. 2 and 3, the valve assembly 220 and the detergent input device 300 are connected to each other by a hose 230. In order to easily connect the valve assembly 220 and the detergent input device 300 to each other, the hose 230 is formed of a flexible rubber material. 20 More specifically, the hose 230 consists of a first hose 231, a second hose 232, and a third hose 233, respectively connected to a first terminal 241, a second terminal 242, and a third terminal 243 that will be later explained. Referring to FIGS. 2 and 4, the detergent input device 300 includes a housing 310 inserted into the receiving unit 210 (Refer to FIG. 1), and a dispenser 25 320 detachably mounted at the housing 310. 7 The housing 310 is fixed to the control panel 200 in a screw or hinge coupling manner. The dispenser 320 is detachably mounted at the housing 310 in a drawing manner. For detergent input, a user detachably mounts the dispenser 320 at the 5 housing 310 in a drawing manner by pushing or pulling a handgrip 321a formed at a front surface 321 of the dispenser 320. Referring to FIGS. 4 and 5, the dispenser 320 includes a first storage unit (R1) for storing a large amount of powder detergent; second storage units disposed at both sides of the first storage unit (R1) for storing a small amount of io powder detergent or a fabric softener and a cap 322 installed at an upper side of the first storage unit (R1). The cap 322 includes an inclined wall 322a having a hole at a central portion thereof. Washing water dropped on the inclined wall flows down into the first storage unit (R1), and the powder detergent contained in the first storage unit 15 (Ri) is prevented from being discharge out of the first storage unit (RI) due to the inclined wall 322a. Siphon pipes (S) are installed at each bottom of the first storage unit (R1)and the second storage units (R2). Detailed explanation for the construction and operation of the siphon pipes (S) will be omitted by referring to Korean Laid 20 Open Patent Publication No. 10-2006-85978. Insertion spaces (T) are formed between the first storage unit and each of the second storage units. And, guide members 312 are vertically installed in the housing 310 so as to be inserted into the insertion spaces (T) when the housing 310 and the dispenser 320 are coupled to each other. The guide members 312 25 guide the dispenser 320 to be coupled to the housing 310, and support the 8 dispenser 320 having been coupled to the housing 310. A terminal 240 for supplying washing water to the first storage unit (R1) and the second storage units (R2) is installed on an upper surface of the housing 310. The terminal 240 is connected to the valve assembly 220 by a hose 230. 5 More specifically, the terminal 240 consists of a first terminal 241, a second terminal 242, and a third terminal 243, respectively connected to a first hose 231, a second hose 232, and a third hose 233. A water dispersing member 313 having a plurality of holes 313a toward an upper side of the cap 322 is installed in the housing 310. The holes 313a of the io water dispersing member 313 serve to uniformly disperse washing water injected onto the water dispersing member 313, and then to introduce the washing water into the first storage unit (R1). Accordingly, the powder detergent contained in the first storage unit (R1) is smoothly mixed with the washing water, and is prevented from being introduced into the basket 130 in the form of a lump. The water 15 dispersing member 313 is installed above the guide members 312 for convenience. A duct 311 extending toward an upper side of the basket 130 is installed at the bottom of the housing 310, and an outlet 311a through which washing water is supplied into the basket 130 is formed at a front side of the duct 311. The duct 311 may be integrally formed with the housing 310, or may be separately formed from 20 the housing 310 thus to be installed at the bottom of the housing 310. Hereinafter, the operation of the detergent input device will be explained. Referring to FIG. 2, for detergent input, a user pulls the dispenser 320 out of the housing 310 in a direction indicated by the arrow 'A' with holding a handgrip 321a of the dispenser 320. 25 Referring to FIGS. 4 and 5, powder detergent is put in the first storage unit 9 (R1), and powder detergent or a fabric softener is put in the second storage units (R2). Then, the user pushes the dispenser 320 into the housing 310 in a direction indicated by the arrow 'B' with holding the handgrip 321a of the dispenser 320. Here, the user may input detergent to the detergent input space 111a. The 5 inputted detergent is mixed with washing water introduced into the detergent input space 111a, and then is introduced into the basket 130 via the detergent input space 111a. Referring to FIGS. 3 and 4, washing water is supplied to each upper side of the first storage unit (Ri) and the second storage units (R2) through the valve 10 assembly 220, the hose 230, and the terminal 240. Then, the washing water is mixed with the detergent contained in the first storage unit (RI) and the second storage units (R2). Here, the water dispersing member 313 is installed above the first storage unit (Ri) containing a large amount of powder detergent therein, and washing 15 water is introduced into the first storage unit (Ri) by being dispersed by the water dispersing member 313. Accordingly, the washing water is uniformly mixed with the powder detergent contained in the first storage unit (Ri). Referring to FIGS. 4 and 5, once washing water introduced into the first storage unit (R1) and the second storage units (R2) reaches a certain level, the 20 washing water is discharged out of the first storage unit (R1) and the second storage units (R2) through the siphon pipes (S) by using the siphon principle. The washing water discharged out of the siphon pipes (S) and mixed with the detergent is introduced above the basket 130 (refer to FIG. 1) through the duct 311, and then is supplied into the basket 130 (refer to FIG. 1) through the outlet 25 311a of the duct 311. Then, laundry is cleaned by general washing processes. 10 Hereinafter, a detergent input device according to a second embodiment of the present invention will be explained in more detail. The same reference numerals will be given to the same parts as those of the first embodiment, and their detailed explanation will be omitted. 5 FIG. 6 is a partial perspective view of a top-loading type washing machine according to a second embodiment of the present invention, and FIG. 7 is a partial planar view of a detergent input device installed at a control panel of FIG. 6. Referring to FIGS. 6 and 7, a detergent input device 400 according to a second embodiment of the present invention includes a housing 410 inserted into 1o the receiving unit 210 (Refer to FIG. 1), and a dispenser 420 detachably mounted at the housing 410 by sliding by a certain angle. The housing 410 is fixed to the control panel 200 in a screw or hinge coupling manner. A duct 311 through which washing water is discharged out is installed below the housing 410. Detergent mixed with washing water at the detergent input 15 device 400 is introduced into the basket 130 through the duct 311. The detergent input device 400 connected to a valve assembly 220 by a hose 230. In order to easily connect the valve assembly 220 and the detergent input device 300 to each other, the hose 230 is formed of a flexible rubber material. More specifically, the hose 230 consists of a first hose 231, a second hose 232, and a third hose 233, 20 respectively connected to a first terminal 241, a second terminal 242, and a third terminal 243 that will be later explained. FIG. 8 is an exploded perspective view of the detergent input device of FIG. 7, FIG. 9 is an exploded perspective view of a housing of FIG. 8, and FIG. 10 is an exploded perspective view of a dispenser of FIG. 8. Here, the dotted arrow 25 indicates water injected from injection holes. 11 Referring to FIGS. 7 to 9, the housing 410 has a rectangular box shape to contain detergent therein, and is provided with a mounting opening 411 for detachably mounting the dispenser 420 at a front surface thereof. The dispenser 420 is inserted into the housing 410 under the guidance of a guide unit 430 5 through the mounting opening 411. Here, in order to insert the dispenser 430 into the housing 410 under the guidance of the guide unit 430, the mounting opening 411 is backward inclined by a certain angle. A stopper 415 for preventing the dispenser 430 having mounted in the housing 410 from moving in the housing 410 by contacting a handgrip 422 is 1o formed at a lower end of the mounting opening 411. A front lower end of the housing 410 is concavely camferred with an arc shape. Accordingly, when the housing 410 is inserted into the receiving unit 210, an empty space (V) is formed below the housing 410. The empty space (V) can be 15 utilized so as to mount components therein, etc. As a result, space loss occurring when the detergent input device 400 is installed at the control panel 200 can be minimized. The housing 410 includes first storage unit (R1), second storage units (R2) disposed at both sides of the first storage unit (R1) and containing powder 20 detergent or a fabric softener therein, partition plates 412 for partitioning the first storage unit (RI) and the second storage units (R2) from each other, and pipes 413 for injecting water to the first storage unit (R1) and the second storage units (R2). Siphon pipes (S) are installed at each bottom of the first storage unit (R1) 25 and the second storage units (R2). Detailed explanation for the construction and 12 operation of the siphon pipes (S) will be omitted by referring to Korean Laid-Open Patent Publication No. 10-2006-85978. A terminal 240 is penetratingly installed at a rear surface of the housing 410 so as to supply washing water, and the terminal 240 is connected to the valve 5 assembly 220 by the hose 230. More concretely, the terminal 240 consists of a first terminal 241, a second terminal 242, and a third terminal 243, respectively connected to a first hose 231, a second hose 232, and a third hose 233. The first to third terminals 241, 242, 243 are connected to pipes each having a plurality of injection holes 413a on a lower io surface, through the injection holes 413a water is downwardly injected to the first storage unit (R1) and the second storage units (R2). Water from the injection holes 413a is injected toward a first receiving unit (S1) and second receiving units (S2). The reason is in order to forcibly flow detergent contained in the first receiving unit (Si) and the second receiving units 15 (S2) into the first storage unit (R1) and the second storage units (R2) by washing off, without allowing the detergent to remain in the first receiving unit (Si) and the second receiving units (S2) when the dispenser 420 is mounted in the housing 410. Referring to FIGS. 8 to 10, the dispenser 420 is formed to have a box 20 shape of which a side surface inserted into the housing 410 has a fan shape. At a front lower side of the dispenser 420, installed is a handgrip 422 held by a user so as to detachably mount the dispenser 420 to the housing 410. As disclosed in Korean Laid-Open Utility Model Publication No. 20-1994 0022755, a door opening unit for opening a door in one touch manner may be 25 installed on a front surface of the dispenser 420. 13 The dispenser 420 includes a first receiving unit (S1) formed in correspondence to the first storage unit (Ri), second receiving units (S2) formed in correspondence to the second storage units (R2), and receiving plates 421 for partitioning the first receiving unit (S1) and the second receiving units (S2) from 5 each other. Under the configuration, when the dispenser 420 is mounted at the housing 410, detergent contained in the first receiving unit (S1) is introduced into the first storage unit (RI), and detergent contained in the second receiving units (S2) is introduced into the second storage units (R2). The receiving plates 421 are provided with slits 421a in a depth direction, io and the partition plates 412 are inserted into the slits 421a when the dispenser 420 is mounted at the housing 410. The slits 421a guide the dispenser 420 to be coupled to the housing 410, and stably support the dispenser 420 having been mounted to the housing 410. Here, the slits 421a may be formed at the partition plates 412 so that the receiving plates 421 can be inserted into the slits 421a. is The housing 410 and the dispenser 420 are provided with a fixing unit, respectively, thereby preventing the dispenser 420 having mounted to the housing 410 from being detached from the housing 410 due to vibration. The fixing unit 440 includes a receiving groove 441 formed at the housing 410; and a frictional protrusion 442 formed at the dispenser 420, and received in 20 the receiving groove 441. According to a design modification, the frictional protrusion 442 may be formed at the housing 410, and the receiving groove 441 may be formed at the dispenser 420. It is also possible to configure that the frictional protrusion 442 directly contacts a side surface of the housing 410 without installing the receiving groove 441. 25 FIG. 11 is a view showing a guide unit formed at the housing and the 14 dispenser of FIG. 8, FIG. 12 is a view showing a state that the dispenser is rotated by a first step with respect to the housing along the guide unit, and FIG. 13 is a view showing a state that the dispenser is rotated by a second step with respect to the housing along the guide unit.. 5 Referring to FIGS. 11 to 13, a guide unit 430 for guiding the dispenser 420 to rotate with respect to the housing 410 is formed at the housing 410 and the dispenser 420, respectively.

And, the second guide protrusion 434 also moves up to a middle portion of the second guide recess 433 along the second guide recess 433. 15 Referring to FIGS. 12 and 13, in order to rotate the dispenser 420 with respect to the housing 410, the user more pulls the dispenser 420 out of the housing 410 thus to rotate by a second step. Accordingly, as shown in FIG. 13, the first guide protrusion 432 of FIG. 12 is detached from the first guide recess 431, and the second guide protrusion 434 moves up to the end of the second guide 20 recess 433. Referring to FIGS. 10 and 11, the user puts powder detergent in the first receiving unit (S1), and puts powder detergent or a fabric softener in the second receiving unit (S2). Then, the user pushes the dispenser 420 into the housing 410 in a direction indicated by the arrow 'B' with holding the handgrip 422 of the 25 dispenser 420. 16 Referring to FIG. 8, since the first receiving unit (Si) is disposed at the first storage unit (R1), detergent contained in the first receiving unit (S1) flows to the first storage unit (R1). Likewise, since the second receiving units (S2) are disposed at the second storage units (R2), detergent contained in the second 5 receiving unit (S2) flows to the second storage units (R2). Referring to FIGS. 6 to 8, washing water is supplied to the first storage unit (RI) and the second storage units (R2) through the valve assembly 220, the hose 230, the terminal 240, and the pipe 413. Then, the washing water is mixed with detergent contained in the first storage unit (Ri) and the second storage units io (R2). Here, water from the injection holes 413a is injected toward the first receiving unit (Si) and the second receiving units (S2), thereby forcibly flowing down detergent remaining in the first receiving unit (S1) and the second receiving units (S2) into the first storage unit (RI) and the second storage units (R2) by being washed off. is Once washing water introduced into the first storage unit (R1) and the second storage units (R2) reaches a certain level, the washing water is discharged out of the first storage unit (RI) and the second storage units (R2) through the siphon pipes (S) by using the siphon principle. The washing water discharged out of the siphon pipes (S) and mixed with 20 the detergent is introduced above the basket 130 through the duct 311, and then is supplied into the basket 130. Then, laundry is cleaned by general washing processes. As aforementioned, in the top-loading type washing machine having a detergent input device according to the present invention, the detergent input 25 device is installed at the control panel. Accordingly, a process for opening a lid and 17 putting a user's hand into a cabinet for detergent input can be omitted. Furthermore, can be solved a problem occurring when the user inputs a precise amount of detergent to a detergent container inside the dark cabinet. As a result, the entire process for detergent input can be simplified. 5 Furthermore, since the detergent input device is installed at the control panel not inside the top cover, the entire appearance is not degraded even when the top cover is formed of steel. A lower end of the housing of the detergent input device is inwardly camferred with an arc shape. Accordingly, when the housing is inserted into the 10 receiving unit, an empty space is formed below the housing. The empty space can be utilized so as to mount components therein, etc. As a result, space loss occurring when the detergent input device is installed at the control panel can be minimized. Furthermore, water from the pipes of the housing of the detergent input 15 device is injected toward the first receiving unit and the second receiving units of the dispenser, thereby forcibly flowing down detergent remaining in the first receiving unit and the second receiving units into the first storage unit and the second storage units by being washed off. Accordingly, inputted detergent can be completely used for a washing process, thereby reducing a usage amount of 20 detergent. The foregoing embodiments and advantages are merely exemplary and are not to be construed as limiting the present invention. The present teachings can be readily applied to other types of apparatuses. This description is intended to be illustrative, and not to limit the scope of the claims.
