Mounted on top of the outer washing machine tank 1 is a substantially donut-shaped outer tank cover 8 on which perforations and inner lids 9 are provided to open and close the outer tank cover 8. Disposed on the bottom of the outer washing machine tank 1 is an electric motor 1A which is connected to the vibrator 6 or the inner washing machine tank 2 by a 20 clutch assembly 11. The clutch assembly 11 selectively transmits the electronic motor. The driving force generated is based on the operating mode of the washing machine to the washing shaft 7 or the dewatering shaft 5. That is, the driving force from the electronic motor 1〇 is transmitted to the washing shaft 7 to rotate the vibrator 6 connected thereto in the washing mode, and it can be conveyed to the dehydrating shaft 5 to rotate the washing machine in the dehydration mode 1275677. Slot 2. A housing cover 12 having an opening is coupled to the top of the housing 3. Mounted on the casing 12 is an outer cover 13 for opening and closing the casing cover 12, and a water injection valve 14 for injecting water into the inner washing machine tank 2. The cleaning liquid is supplied to the outer washing machine tank 1 via the water supply hose 5 15 . A drain valve 16 is provided on the bottom of the outer washing machine tank 1, which discharges washing water from the outer washing machine tank. The washing machine having the above configuration operates in the following manner.

If the cleaning liquid reaches a pre-face in the washing machine tank 2, the / main water valve 14 is closed and the electronic motor 1 is operated. The driving force generated by the electric motor 1 施加 is applied to the vibrator 6 via the washing shaft 7 with the clutch assembly U to rotate the vibrator 6. When the vibrator 6 is rotated, the laundry is subjected to strong friction and water flow, and the clothes are subjected to contact between the clothes and between the vibrator 6 and the inner washing machine tank 2, and thus are cleaned. After the cleaning operation is completed as described above, the dehydration operation can be started. The drain valve 16' is opened and discharged from the inner washing machine tank 2. Then, the clutch assembly 11 is switched to the dehydration shaft 5, which in turn transmits the amount of driving force generated by the electric motor 10 to the inner washing machine tank 2. As a result, the laundry is dehydrated by the centrifugal force of 20 in the rotation of the washing machine tank 2. However, it is also possible to dry the inner washing machine tank and the outer washing machine tank in accordance with the construction of the conventional washing machine. Therefore, even after the cleaning process is completed, the water for washing clothes including mold and bacteria is maintained in the washing machine tank and the outer washing machine tank. 1275677 t MODIFICATION 3 SUMMARY OF THE INVENTION Accordingly, the present invention is directed to a washing machine capable of drying a washing machine tank and a washing machine tank outside the washing machine to prevent mold and bacteria from growing therein.

Because the vertical: some parts of the clothes and the same figure of the conventional washing machine of Figure 4 are the same The components used for the corresponding or identical surfaces are omitted, and the detailed description thereof is omitted. Referring to Fig. 1, there is shown a washing machine 0 15 according to the first embodiment of the present invention, as shown in the figure, on the side wall and the bottom surface of the washing machine. The inner washing machine tanks 17 of the plurality of cleaning liquid flow holes 18 are rotatably mounted in the washing machine tank 1 outside the top opening. The shape has a substantially donut shape, and a perforated outer tank cover is provided on approximately the middle portion thereof. 19 is mounted on the top of the outer washing machine tank, and the inner cover 20 is configured to open and close the perforation of the outer tank cover 19. The casing 20 cover 21 is disposed on the top of the casing 3. It is mounted on the rear inner portion of the casing 3 (the The top right of 1@ is a powerful hot air unit 26 for drying the inner washing machine tank 17 and the outer washing machine. The powerful hot air unit 26 includes a fan 22 and a hot air passage 25 on which the heater 24 is mounted. One side of the fan 22 is passed through the suction filter 23 The housing 3 is externally connected, and the other side is connected to the hot air passage 25, 1275677, the hot air passage 25, to the flexing manifold 27, and the flexible hose 27 is connected to the hot air to be injected into the outer tank cover 19 through the hole. The hot air inlet hole 28 is inside the washing machine tank 17. The teaching * is turned on the outer tank 19 to heat #" (4), and the discharge has been supplied by the milk population hole 28 to the heat μ in the washing machine tank 17. This adjacent heat ^Export (4) (4) Set 岐切科μ, bribe (4) detachably mounted thereon to cover the hot air outlet hole 29. 10 The cleaning fluid flow hole 18 defines an open or circulation portion for injection by strong hot air The hot air in the washing machine (4) is inserted into the inner space 32 between the inner washing machine tank 17 and the outer washing machine tank 1. In addition, a circulator 33 for promoting hot air circulation is provided in the bottom of the washing machine and the bottom. On the bottom of the inner space 32 between the surface and the outer washing machine tank 1. The circulator 33 is connected to the inner washing machine tank 17' to rotate therewith. The washing machine further includes a controller 34 which controls the electronic motor 1 and the water injection 15 valve 14 Operation of the drain valve 16, etc., for continuous control A series of washing and dehydrating steps. Further, the controller 34 controls the laundry drying operation in which the laundry in the inner washing machine tank 17 is dried by the hot air blown out by the strong hot air unit %. In addition, the hot air is heated by the strong air. When the hot air unit 26 is supplied into the inner washing machine tank 17, the controller 34 simultaneously rotates the inner washing machine slot 2 to send the hot air therein to the inner space 32 for the drying operation of the tank. The washing machine operates in the following steps. If the user places the laundry into the inner washing machine tank 17 and starts the washing operation, the water filling valve 14 is opened, and the washing liquid is injected into the inner washing machine tank 17 via the water supply hose 15 to a predetermined height of 1275677. . Then, the water injection valve 14 is closed and the electronic motor 1 is started. The driving force generated by the electronic motor 10 is supplied to the vibration 6 by the clutch assembly U to rotate the vibrator 6. The rotation of the vibrator 6 causes contact between the laundry itself, and contact between the inner washing machine tank 17 and the vibrator 6, thus generating 5 friction and water flow for washing the laundry. During the dehydration process after the cleaning operation is completed, the drain valve 丨 6 is opened to discharge the cleaning liquid from the inner washing machine tank 17. Then, the clutch assembly u is switched to the dehydration shaft 5 connected to the electric motor 10 to rotate the inner washing machine tank 17. Then, the rotation of the inner washing machine tank 17 causes the laundry contained therein to be dehydrated by centrifugal force. In the next laundry drying operation, the drain valve 16 is closed. Then, the clutch is converted into the washing shaft 7 connected to the vibrator 6 in order, and the electronic motor 10 is sequentially allowed to rotate the vibrator 6 in a clockwise and counterclockwise direction to agitate the laundry and the heater 24 and the fan 22 to be supplied thereto. The current operation 15 causes the atmospheric air absorbed by the suction filter 23 to be heated, and then the obtained hot air is sent to the inner washing machine tank 17 through the hot air inlet hole 28. Hot air heats the clothes being agitated and evaporates the moisture contained in the clothes. Thereafter, the hot air rises toward the upper portion of the inner washing machine tank 17, and is discharged through the hot air discharge hole 29. 20 Next, after the drying process is started, the drain valve 16 is opened again, and the electronic motor 10 is operated to rotate the vibrator 6. Further, the fan 22 and the heater 24 are operated with a current applied thereto to heat the atmospheric air-vacuum absorbed by the suction filter 23 through the hot air inlet port 通过 in the direction indicated by the arrow, A// The air inlet hole 28 sends the obtained hot air to the inner washing machine tank 17. At 1275677, the inner washing machine tank 17 and the vibrator 6 are rotatable to improve the efficiency of the tank operation. The hot air injected into the inner washing machine tank 17 is dissipated into the inner space 32 through the π washing liquid flow hole 18 provided in the washing machine tank 17, as indicated by an arrow. Therefore, the internal space 32 is filled with hot air over time. 5 Since the hot air is filled and dissipated into the internal space 32, the inner washing machine tank 17 and the outer washing machine tank 1 can be effectively dried. Here, since the cleaning liquid flow holes 18 are formed on the bottom surface and the side walls of the washing machine tank 17, the hot air injected into the inner washing machine tank 17 is sent to the internal space 32 through the washing liquid flow holes 18, and then passes through the holes. rise. Therefore, the internal space 32 is filled with hot air so that the inner washing machine tank 1 and the outer washing machine tank 1 can be effectively dried. Further, it is preferable to rotate the inner washing machine tank 17 during the tank drying operation because the rotation of the inner washing machine tank 17 accelerates the hot air from the inner washing machine tank to the outer washing machine tank 1. Further, by rotating the vibrator 6, a rapid air flow can be formed in the inner washing machine tank 17, which improves the efficiency of the tank drying. Further, when the hot air in the inside of the washing machine tank 17 is sent to the filling internal space 32, the hot air around the bottom of the internal space 32 is circulated by the money II33 connected to the bottom of the inner washing machine tank 17, to rotate therewith. . Therefore, the inner washing machine tank 17 and the outer washing machine tank can be efficiently dried in advance. 20 When the laundry is treated in accordance with the first preferred embodiment of the present invention, the drying step is performed after the -series washing, washing, and dehydrating operations are completed. However, since the drying operation does not have to be performed frequently, this drying step can be omitted. Further, the washing machine of the present invention can be designed to have only an operation mode of washing, washing, and tank drying without a clothes drying mode. * 1275677 Referring to Figure 2, there is shown a laundry machine in accordance with a second embodiment of the present invention. As shown, the inner washing machine tank 17a having a plurality of cleaning liquid flow holes 18 on the side wall is rotatably mounted in the outer washing machine tank 1. The inner washing machine tank 17a is provided with an air guiding portion or an element 35 as an air guiding device. The air guiding portion 5 35 projects outward from the periphery of the inner washing machine tank 17a. Each of the air guiding portions 35 is adjacent to a corresponding cleaning liquid flow hole 18 to guide the hot air toward the bottom of the internal space 32 from a corresponding cleaning liquid flow hole 18. Since the rest of the washing machine in the second embodiment corresponds to the first embodiment, the same reference numerals are used herein, and the description thereof is omitted. The operation of the washing machine in accordance with the second embodiment will be described below. Since the steps from the self-washing to the laundry drying operation are the same as those of the first embodiment, the description thereof will be omitted. When the tank drying step is started, the hot air supplied to the inner washing machine tank 17a is sent to the inner space 32 between the inner washing machine tank 17a and the outer washing machine tank 1, 15 and filled. Thereafter, when the inner washing machine tank 17a is rotated, the hot air in the inner washing machine tank 17a flows out of the inner washing machine tank 17a through the washing liquid flow hole is, and is guided by the air guiding portion 35 in the arrow in the second drawing, The direction shown is directed towards the bottom of the interior space 32. The hot air collected at the bottom of the internal space 32 is effectively dissipated in the internal space 32 to effectively dry the inner washing machine tank 17a and the outer washing machine tank 1. Referring now to Figure 3, there is shown a washing machine in accordance with a third embodiment of the present invention.
