Description

201002902 VI. Description of the Invention: [Technical Field] The present invention relates to a drum type washing machine which is formed in a water tank and has a bottomed cylindrical shape. The drum is driven by rotating the rotating drum to wash the laundry contained in the rotating drum. c. Previously, the background of the invention is known. The drum type washing machine is known to have a circulation function of circulating water in the water tank 10 by a circulation pump. For example, Japanese Patent Laid-Open Publication No. - (Special) Document 1) uses one system in each of two conditions. The first is to use a material circulation pump in the washing sequence or the washing process, and to circulate the washing water or the washing water, and to achieve the active mixing of the lotion and the washing water in the initial stage of the washing process, and dissolve the early stage of the lotion. The second system is used in dehydration or drainage procedures

Li is used as a row of fruit, and in the circulation side of the circulation pump, a tank is disposed on the side of the water absorption side, and laundry debris such as slag in the water is collected, whereby the laundry chips do not enter the circulation pump. Further, in Japanese Patent Laid-Open Publication No. 2005-58741 (Patent Document 2), the water in the water tank is circulated by the circulation fruit, thereby preventing the lotion from accumulating in the heating space or the specific space. It is disclosed that there is a technique for rapidly heating laundry in a laundry rain to improve laundry efficiency. Further, as an example, JP-A-2006-223572 (Patent Document 3) discloses a technique in which a circulation pump unit is disposed on a platen at the bottom of a washing machine outer casing 3 201002902, and the circulation pump unit includes : Circulating pump part; and filter part, which is a person who catches the wire slag. By arranging the circulation pump portion on the platen through the elastic pad, the vibration of the pump motor is prevented from propagating to the platen, and as a result, the noise caused by the vibration of the pump motor and the vibration of the outer casing can be prevented. In addition, Japanese Laid-Open Patent Publication No. 2006-239142 (Patent Document 4) discloses a technique of spraying water in a water tank to a heater for drying in addition to the inside of a rotating drum. Remove the slag attached to the heater. 10 However, the technique of the water circulation disclosed in the above-mentioned Patent Documents 1 to 4 is made to inject the circulating water into the rotary drum from the pipe end, and therefore, the intentional circulating water can only be sprayed in the washing drum. Part of the object, and can not fully utilize the cycle effect. Therefore, the technique disclosed in Patent Document 2 and Patent Document 4 employs a special jet nozzle to eject 15 to a wide area. However, in particular, the jet nozzle may cause a rise in cost, and since the pump pressure must be increased, At the same time, it will become the cause of rising costs. Further, in the technique disclosed in Patent Document 1, Patent Document 3, and Patent Document 4, the piping of the water circulation system penetrates the end wall portion of the water tank and faces the structure inside the rotary drum, and the piping structure becomes more complicated and becomes advanced. 20 reasons for the increase in cost. SUMMARY OF THE INVENTION The present invention provides a drum type washing machine that circulates water in a water tank by a circulation pump, and uses circulating water from a circulation path of the circulation pump to the rotating drum. The spitting structure is simple and the cost can be reduced. The present invention relates to a drum type washing machine in which a rotary drum formed in a bottomed cylindrical shape is disposed in a water tank so that a front side of the opening is formed in a direction of a rotation axis toward a rear side of the bottom portion 5 to form a horizontal or horizontal direction. At least one of a washing process and a washing process can be performed by tilting the motor and driving the rotating drum by a motor. The washing machine includes a water circulation mechanism that is connected to the water tank by a circulation path. In the water circulation in the water tank, the water circulation mechanism has a flow path, and the flow path is disposed between the inner surface of the end wall before the 10 water tank and the front end wall surface of the rotary drum, and discharges the circulating water into the rotary drum. According to the above configuration, as long as the circulation path is connected to the front end wall of the water tank, the circulation path can be connected to the flow path formed between the front end walls of the water tank and the rotary drum. Therefore, the water circulation mechanism is circulated by the circulation pump and the circulation path. 15 When the water in the water tank is sucked into the water tank and circulated in the washing program or the washing program, it is not necessary to be specially piping, and can be formed in each of the front end walls via the flow path. The annular outlet between the circumferences allows the circulating water to be discharged into the rotating drum. Further, the circulating water can be discharged from the annular outlet 20 between the inner peripheral portions of the front end walls via the flow paths between the respective front end walls of the water tank and the rotary drum.

I: Embodiment 3 201002902 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, a drum type washing machine according to an embodiment of the present invention will be described with reference to Figs. 1 to 9C, and the following description is a specific example of the present invention, and is not limited to the patent application. The content revealed by the scope. 5 帛 1 is a cross-sectional view showing a drum type washing machine according to an embodiment of the present invention. In the drawings, the drum type washing machine of the present embodiment is the same as the conventional one, and has a mode setting or control program. The electric motor 6, the water supply mechanism 7, the drainage mechanism 8, and the drying mechanism 9 are automatically controlled to perform at least the functions of washing/precise, washing, rinsing, dehydrating, and drying. However, the drying mechanism 9 is not essential. Further, in addition to the above, in the present embodiment, the following functions are also provided, and P is circulated in the water tank 3 by the water circulation mechanism 16 in the case of the cleaning preparation program, the cleaning process, and the cleaning process. And reach the early dissolution of the lotion, the prevention of bias or the improvement of washing or washing function. Water supply

15 = 7 is a mechanism in which an external faucet is placed in the water tank 3, and the water supply machine: can be supplied in a timely manner by a solenoid valve switch as indicated by a solid arrow symbol, and is configured to use a water supply to wash the lotion. The lotion in the accommodating portion is put into the water tank 3. 20, by dewatering (1) financial shadows, water, and financial institutions 8 can wait for the necessary: switch at the end of the washing program, at the end of the washing process, set the (four) heart line (four) domain reading drainage. The dry type 9 system is equipped with the blower 12 and the water tank 3 to circulate. The internal structure 9 has a flow path of the water tank 3 and the rotating drum 4 ... the dotted line (four) is cycled, and the transition unit i 5 is disposed on the drying cycle path at 7 201002902, which is collected The line slag of the air introduced from the rotating drum 4 of the water tank 3 is _, and the dehumidification material is disposed on the dry circulation path, and the introduction of the scale after dust removal = order dehumidification, X, on the drying cycle path The heating unit U^ is configured to heat the dehumidified air to make dry high-temperature air. By placing the feeds and the second portions downstream of the heating unit u, it is difficult to be affected by moisture. Further, the dehumidifying unit 1G and the heating unit n are evaporators that exchange heat between the refrigerant circulating air and the circulating air by the compressor 17. And the condenser is reduced to the air conditioner 18, however, the drying mechanism 9 is not limited thereto. The σ ” water circulation mechanism 16 is repeatedly sucked into the water tank 3 by the circulation pump 2〇 and returned to the water tank 3. The mode of operation stroke or the like is selected by the money placed on the front surface of the washing machine body 2 When the operation panel 21 is input, the button mechanism 22 notifies the user of the display unit on the operation panel 21 based on the input information. If the operation is interrupted by the input setting unit on the operation panel 21, The water level detecting unit such as the water level in the water tank 3 detects the wheeled data and starts driving. Thus, the operation of the drain valve, the water supply valve, and the like is controlled, and the operation of washing, dehydrating, drying, etc. is performed. The rotary drum 4 is attached to the rotating shaft. 4a directly combines the motor 6 that has been installed in the water tank 3, and is disposed at the same time as the water tank 3 so that the direction of the rotation axis is inclined from the horizontal direction by an angle Θ = 20 degrees ± 1 degree from the opening side toward the bottom side, whereby Compared with the setting in the horizontal direction, even if the rotating drum 4 is disposed in the same direction, the opening of the water tank 3 and the rotating drum 4 will be formed obliquely upward, so that the user does not take a distraction such as bending. It is easy to remove and put 201002902 into the laundry. Especially according to the experience of the inventor, the angle of inclination is 20 degrees ± 10 degrees, so that even if there is a difference between the height of the child (except the child) to the adult or In the case of a wheelchair user, it is possible to obtain the state in which the laundry is most easily taken out and placed in the work. Further, the water supplied to the rotary drum 4 is accumulated on the back side, and also has a small amount of water. The advantage of the deep water storage state. In order for the water supply to effectively act on the laundry in the rotary drum 4, the water tank 3 has the same inclination as the rotary drum 4 and is disposed along the vicinity thereof.

Further, the washing machine body 2 is provided with a switch door 5, and the opening 13 of the water tank 3 can be sealed and opened by passing through the sealing member 14 which is mounted on the σ edge thereof. In addition, the driving of the rotary drum 4 is performed by a continuous rotation at a high speed such as i rpm, thereby causing entanglement and twisting of the laundry in the washing or washing process. When the pleat is opened, it is directly attached to the (4) of the rotary drum 4 to cause creases. As a result, it is difficult to take out the laundry and it is troublesome to handle afterwards, and the laundry is likely to leave a serious flop and 15 wrinkles. time. In order to solve this problem, in the present embodiment, in the laundry program, the laundry program, and the washing program, in order to greatly improve the entanglement and the occurrence of entanglement (4), the 20-domain high mechanical force is also less likely to cause wrinkles, and Two modes are described for control. The first-stage positive and negative arc rotation drive mode, the bean system interaction t the reverse rotation cylinder 4's large (four) degree, cut 1 (10) abrupt positive arc rotation, acute reverse arc rotation. The second system is a continuous rotation of the 1L symbol driving mode, which is reversely and interactively repeated to display the movement of the laundry lifted by the rotation of the drum 4 from the height of the weight of the drum itself. The aforementioned rotating roller under the yoke rotation speed is continuously rotated by 4. In the washing program, the salt washing program and the washing program 9 201002902, the forward and reverse arc rotation driving mode and the forward and reverse continuous rotation driving mode are alternately implemented, whereby the rotating drum 4 can be more than 90 degrees and less than 180 degrees. The rapid rotation of the arc and the rapid braking, lifting the laundry to a maximum of more than 90 degrees and less than 180 degrees. Furthermore, it is possible to surely achieve a braking state by the sudden braking of the final stage of the lifting of the washing material, and peeling off the laundry from the inner surface of the rotating drum 4 by its inertia and its own weight, and by its own weight Falling to the left and right opposite sides of the lifting side, therefore, in the case of a laundry which is hydrated and very swelled and is in a state of slack and slippery, it is particularly possible to impart a high unwinding action and at the same time impart mechanical force to the laundry, thus Can improve the clean performance of 10 washes. Furthermore, the positive and negative arc rotations in the forward direction of the arc rotation drive and the reverse reverse arc rotation mode can be alternately rotated to form a positive and negative arc rotation driving mode, whereby the arc rotation can be performed by the forward and reverse interaction. Driven, the lifting position and the falling position of the laundry are alternately exchanged in each arc rotation drive, so that the laundry can be further prevented from tangling and the function of the unwinding 15 can be further improved, and the washing can be increased. The number of mechanical forces can improve the cleaning performance. Moreover, by the high unwinding action, it is possible to suppress the entanglement of the laundry materials caused by the washing and washing procedures, thereby continuously performing the slap washing in the forward and reverse arc rotation mode to improve the washing effect. And wash the effect. 20, if only the forward and reverse arc rotation drive mode is used, the entanglement, twisting, wrinkles, and the like of the laundry can be reduced, and on the other hand, the laundry is not easily replaced in the up and down direction, and the laundry at the bottom of the rotary drum 4 is washed. It is not easy to move, so it is easy to cause uneven washing. However, by using the forward-reverse continuous rotation driving mode in combination, the position of the laundry in the up-and-down direction can be replaced, that is, the tangling of the laundry in the positive and negative continuous rotation driving mode is reduced by 10 201002902, It twists and wrinkles, and at the same time reduces the imbalance of the mechanical force of the laundry in the forward and reverse arc rotation driving mode. Accordingly, the laundry can be washed or washed in two different actions by two modes, that is, in particular, by driving the 5 mode by the forward and reverse arc rotation, the entanglement and twisting of the laundry can be reduced. The wrinkles are generated and a sufficient rinsing action is imparted, and the washing operation is performed in a continuous reverse rotation driving mode, thereby imparting a uniform washing operation capable of continuously moving the laundry and reducing unevenness, and is effective for stubborn dirt. f 1 In the drying process, especially if the forward and reverse arc rotation drive mode is implemented, 10 is suitable for the ironing pleats of the dehydrated laundry, and the finished quality is particularly improved, and the rework can be greatly reduced. However, since the washing process of the drying process is light and sometimes it is difficult to stick to the inner surface of the rotary drum 4, the rotation angle of the rotary drum 4 is preferably set to 90 or more and less than 200. The maximum rotation speed 15 of the rotary drum 4 in the forward and reverse continuous drive mode can be made as usual as 45 printing 111±51^111, and the maximum rotation speed of the rotary drum 4 in the forward and reverse arc rotation driving mode is laundry and washing. In the program, it should be made to ί: 40 rpm or more, and after dehydration, it is suitable for 50 rpm or more. However, if the circulation pump 20 for circulating the water in the water tank 3 is disposed on the platen 2a at the bottom of the washing machine body 2 as is conventionally known, the arrangement of the water circulation path connecting the circulation pumps 20 and 20 of the water tank 3 is restricted. In other words, there is a change in the distance or positional deviation between the respective connection positions of the circulation pump 20 fixed to the fixed side of the platen 2a and the water tank 3 on the vibration side, and therefore, it is necessary to have the flexibility to absorb the change. A flexible hose or the like is connected, and as a result, the hose is deteriorated due to vibration or repeated vibration and vibration accompanying the vibration. It is predicted that water leakage will occur. Therefore, in the present embodiment, the circulation pump that circulates the water in the water tank via the water circulation path 31 is installed in the water tank 3, and as shown in Figs. 2 and 3, the filter 32 for filtering the circulating water is placed in the water tank 3. The water inhalation portion 3 of the water is taken in when the water is circulated. Fig. 2 is a cross-sectional view showing a water suction portion and a drain port portion of the drum type washing machine in the embodiment, and Fig. 3 is a plan view showing a water suction portion and a drain port portion of the drum type washing machine in the embodiment. Accordingly, when the circulation pump 20 is attached to the water tank 3, the water-receiving path 3 i connected to the other is connected to the same water at the same time as the circulating poly 3 借此 3 'by this 'even Due to the vibration of the water tank 3, the distance between the connection positions or the positional deviation can be avoided, so that the circulation path 31 between the circulation_and the water tank 3 does not need to be stretchable or flexible. Further, since the water circulation is possible between the water tank 3 and the circulation pump 2 attached to the water tank 3, the U water in the water tank 3 can be circulated by the piping structure which is short and durable. Further, the circulation pump 2G does not increase the vibration source for the vibration of the water tank when the rotary drum* is driven by the washing unevenness, and can impart the vibration-damping action to the water tank 3 by its weight. Further, the filter 32 is attached to the water from the water tank 3 in the water circulation path 3丨. And the spurs are placed in the side of the water tank 3 and exposed, so that the slag-like intrusion 2 is prevented from entering the water-supply side path 3a of the % path 31 or the circulation pump 20, and maintenance is not required. As described above, since the circulation pump 2A is attached to the water tank 3 at the same time as the water circulation path 31, between the connection position of the circulation pump 2A and the water circulation path 31, and the connection position between the water tank 3 and the water circulation path 31,吁 避免 12 201002902 Due to the change in the distance of the vibration of the water tank 3 or short, the piping structure is simple and palpitations. Also, the water circulation path 31 is used for the benefit pumping - 5 10

20 materials with excellent mobility, heterogeneous, flexible and anti-vibration ring path 31 series, simple and volume is =: daily molded products, etc., therefore, water can be changed, and can be taught at a low cost. The function of the sex clothes machine. In addition, the cycle (4) improves the source of washing for the forest 3 without paying the money ring, and can use the weight of the system / 4 squares to vibrate and ensure the quiet operation and prevent the increase of the service life, and the female attack in the direction of the week And the axis side, the fine 2 is recorded in the water-collecting water suction part 33 of the water-conserving view (4) and can also avoid the water-absorbing side path 3U' of the line_invading water circulation path η, and the circulation pump 20 is taken for granted. The class does not block, damage or break the water circulation system 16 on the water side path 3_ or the Wei 2 leaf, so there is no need to carry out special maintenance on the line slag, and the circulation can be ensured for a long time. Here, Fig. 4 shows a three-dimensional model of the main part of the drum type washing machine of the present embodiment, '5A to 5C1J, which is the same as the circulation pump used in the drum type washing machine in the embodiment. The plan view, the side view and the lower view. As shown in Fig. 4, the circulation pump 20 abuts against the bottom 3b of the water tank 3 from below, and is fixed by a bolt 34 or the like, and the water circulation path 3i comes from the circulation pump 2〇. The spit side path 3lb is facing the water 3, the opening π of the washing machine body 2 is located before, and as shown in Figures 1 to 4 'has 2 相对 with respect to the horizontal direction. The above ascending inclination and extension, specifically, the circulation pump 20 is like 5A to 5C As shown in the figure, the resin pump casing 20b in which the movable impeller 20a is housed is attached to the opening side 13 201002902 5 10 15 20 , and the bearing partition wall 2_ parallel body in the front end of the metal motor casing located in the circulating electric motor e And the 'fourth' of the impeller is directly combined with the motor shaft, that is, it is embedded in the tree (four) mounting seat, and the mounting seat (10) has a substantially c-shaped mounting core at three locations (Fig. 5C). As shown in the fourth figure, the scale mounting piece 35a is fitted from the fine 3 of the money 3 to the volute portion 3c which is protruded downward, and the bolt 34 is twisted into the wheel portion 3e, whereby the circulation pump 20 is detached from the lower wire. After reading the bottom material of 3, and the axis of the 环环果 2〇 is longitudinal, and even if the circulating motor 2〇c is located on the upper side of the pump casing, it does not constitute an obstacle. 借此 Thereby, the circulation pump 20 can be self-maintained during maintenance. Easily loading and unloading 'under' under the sink 3 can be formed from the sink 3 to form the washing machine body 2 The lower circulation pump 2G below the bottom portion of the side, the discharge side path 31b is realized by the inclination of the water tank 3 along the rotary drum 4 or the shortest pipe along the cylindrical shape, that is, in order to face the washing machine body 2 When the portion has a rising inclination of 2 〇 or more with respect to the horizontal direction, it does not constitute a complicated structure. Further, the circulation pump 20 absorbs water in the water tank 3 via the water absorption side path 31a, and sends it to the discharge side path 31b. When it is discharged into the water tank 3, the inclined discharge side path 31b smoothly discharges the air from the pump casing 2b to the discharge side path 31b. Therefore, the circulation pump 20 can be prevented from being in the pump casing 2 b The so-called air intake phenomenon in which air is entangled in the water is absorbed, so it is easy to carry out the maintenance of the circulation pump 2 。. Here, the inclination angle of the rotary drum 4 is made 2 turns. Soil 1 〇. When the discharge side path 31b which is formed to have a rising inclination of 20 or more is formed in a condition that the inclination angle is larger than the inclination angle of the rotary drum 4, the composite can be formed by the curved shape of the cylindrical surface of the circumferential direction of the water tank 3. Will not take off 14 201002902 The shortest pipe from the sink 3. Further, as shown in Fig. 2, the circulation pump 20 is slightly inclined in accordance with the inclination of the water tank 3, and is formed as a lower portion of the pump casing 20b from the axial direction in the longitudinal direction, specifically, an L-shaped suction port integrally formed at the lower portion. After the water is absorbed, the peripheral wall of the water tank 3 is specifically discharged through the discharge port 20g (Fig. 4) integrally formed in the tangential square. Therefore, as shown in Fig. 2, compared with the drain valve 19, and the drain valve 19 is provided in the drain path 8a for draining the water in the water tank 3 to the drain system 8 of the outer casing f, the pump casing 2〇b The lowermost portion 31c of the water circulation path 31 is located at a high position and reaches a height position which is equal to or lower than the upstream of the drain valve n1〇 in the drain path 8a, that is, the pump housing 20b and the lowermost portion 31c of the water circulation path 31 are formed. At the same level, or extending to the lower side and connected to the upstream position of the drain valve 19 in the drain path 8a, this opens the row. The fire valve 19 makes the water in the peripheral device 20b and the water channel % control 31 common to the same. It is convenient when the lowermost portion 31c naturally flows out into the drainage path 8a. Thereby, the pump casing 20b and the lowermost portion 3lc of the water circulation path 31 constitute a place where the residual water inside the circulation pump 20 or the drainage path 8a is naturally fluidized. The drain path 8a is opened to the same level as the upstream of the drain valve 19, and accordingly, when the drain of the drain valve 19 is opened, the water remaining in the water circulation path 31 and the % pump 20 is naturally drained via the drain path 8a. Therefore, the 2 〇 water circulation path 31 includes a circulation pump 2 〇 to drain the internal residual water while draining the water in the water tank 3, and does not require a separate drainage structure or drainage control. Here, as shown in Fig. 2, the drain path 8a and the water circulation path 31 are formed integrally, and the f tank 37 is shared, and the water tank 37 is sucked from the drain port 36 of the water tank 3 connected to the drain path 8a and water. The portion 33 receives water. The water storage tank system 15 201002902 has a water absorption pipe field 37a toward the side of the circulation pump 2 and a drainage pipe field 37b toward the drainage channel 8& side, whereby the water absorption can be formed by the water storage tank 37 The piping area 37a and the drainage piping area 37b receive the water absorption from the water suction portion 33 of the water tank 3 and the drainage from the water discharge port, and simplifies the water storage 5 structure or the sealing structure. The water absorption system received in the water absorption piping field 37a corresponds to The water absorption in the circulation pump 2 via the water absorption path 31 and the drainage received in the drainage pipe field 37b correspond to drainage through the drainage path. Although this is the correspondence, the water storage tank 37 can make the water circulation path when draining. 31 and the residual water of the circulation pump 20 are naturally drained to the drainage path W 8a 'by the drainage pipe area 3 7 b. That is, the water absorption pipe area 37a and the drainage pipe field 37b which can be formed by the body-shaped water storage tank 37 The water absorption from the water suction portion μ of the water tank 3 and the water discharge from the water discharge port 36 are performed, so that the water storage structure and the sealing structure which are advantageous for maintenance can be sucked by simple and low With the 15th field 37 & the water absorption to the circulation pump 20 and the drainage line via the drainage pipe field 37b. Further, the residual water of the water circulation path 31 and the circulation pump 2〇 can be naturally drained to the drainage path via the drainage pipe field 37b during drainage. 8a, and it is not necessary to carry out special residual water treatment. In the present embodiment, as shown in Fig. 2, the storage pipe area 37 of the water storage tank 2〇37 is the drainage pipe field 37b by connecting the hole field. The communication hole 37 (the partition wall 37c that is provided between the first and second partitions 37c corresponds to the portion that takes the lower portion 31c. The communication hole 37 (1 is provided with the self-draining pipe field, and has a non-return function toward the water absorption and distribution field 37a side). The check valve 38 is provided by the self-draining valve of the stagnation valve 38 in the field 3% _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ When the water absorption side path 31 & the water is immersed in the circulation pump 2, the water of the mixed wire slag does not flow into the water absorption pipe area 37a from the side of the drainage pipe area 37b, so that the inside of the water tank 3 can be made by the circulation pump 2 Water circulation is not a problem. When the drain valve 19 is opened, the drain pipe 31 is drained from the drain pipe 仏5, and the water circulation path 31 and the residual water in the pump casing 20b open the check valve 38 of the communication hole 37d and flow into the drain pipe field 3713 side. Therefore, the natural drainage is not hindered. In addition, the side of the self-draining pipe field 371) of the check valve 38 does not require a particularly complicated structure toward the suction pipe field 373 side. However, it is not limited to the above embodiment, and the water storage is not limited. The tank 37 may be formed to have a predetermined range of the partition wall 37c, specifically, an area larger than the communication hole 37*1, so that the water suction pipe area 37a communicates with the drain pipe area 37b, and a filter (not shown) is installed in the communication portion. Alternatively, the filter portion which is integrally formed can be provided, whereby the check valve of the communication portion between the drain pipe region 37b and the water suction pipe region 37a can be eliminated. Thereby, the water absorbing effect from the circulating pump 20 also reaches the drain pipe area 37b via the communication portion 15, and the water absorbing pipe field 37a is more reasonable. However, since the drain valve 19 is closed, it does not reach the drainage path. In addition to the water absorption from the water suction portion 33 through the filter 32 and the water suction pipe region 37a, the water absorption from the water suction portion 33 through the water outlet 36 and the drainage pipe 37b and the filter or the filter portion of the communication portion It will also be carried out in parallel, and the 20-line slag will not intrude and will reduce the water absorption resistance. When the drainage from the drainage channel 8a is passed through the drain pipe area 37b when the drain j9 is opened, the water in the water circulation path 31 and the pump casing 20b flows into the drainage pipe field via the filter or the filter of the communication portion. 3 7b side, so it does not interfere with natural drainage. In addition, since the water circulation path 31 and the residual water in the pump casing 20b are not 17 201002902 hybrid line>, the surface is not trapped in the water absorption pipe and flows into the drainage pipe field 37b side, so it does not Prevents natural drainage. On the side of the drainage pipe field 37b of the filter or the filter, even if the slag line of the π ^ is not washed away by the drain and is additionally attached, it is also made.

(5) The water is drained from the drain pipe area 37b and drained naturally. The residual water or the line remaining in the water absorption side path 31a and the drainage path 8a is checked by *, '. Special care. Further, as shown in Fig. 2, the water suction portion 33 and the filter 32 are higher than the drain port 36 of the water tank 3 to which the drain path 8a is connected, and are located at a position lower than the lowest water level at the time of water circulation, and are formed so as not to obstruct the sink. The water in 3 flows toward the drain port 36'. In the present embodiment, the filter 32 is fitted in the water suction portion 33' and the water suction portion 33 is opened right above the drain port 36, and the drain port 36 is attached to the lowest portion 3d of the peripheral wall of the water tank 3. The opening, that is, the substantially flat upper surface is located slightly higher than the inner surface of the peripheral wall of the water tank 3, and the opening 15 does not block the flow of water toward the drain port 36, so that the filter 32 can also be made circular in a plan view or An elliptical shape and a dome-shaped or mountain-shaped structure that rises upwards. However, it should be limited to a height below the minimum water level, that is, even if the drainage from the lowest water level is used, the surface can be flowed by the water when draining. It is subjected to the height of the rinsing action described later. In this embodiment, the water suction portion 33 and the filter 32 are located above the water discharge port 36 of the water tank 3 and below the lowest water level at the time of water circulation, and are formed so as not to hinder the water in the water tank 3 from draining. The structure in which the port 36 flows 'so the filter 32 will be filtered and will not be isolated from the water tank 3 'by this' even if the wire slag is attached to the surface of the filter 32, the water will be exposed to the reduced water 18 201002902 The flow of the water storage amount is flushed toward the flow of the water discharge port 36, and as a result, the wire slag which is attached to the drain pipe field 37b when the filter or the screen portion is attached is simultaneously mixed in the drain to be discharged. Therefore, it is possible to avoid the case where the wire slag is accumulated in the filter portion every time the cycle operation is performed, so that it is unnecessary to carry out special maintenance for the residual slag or the wire slag remaining in the water absorbing side path 31a and the drain path 8a. Here, Fig. 6 is a perspective view showing a filter device of the drum type washing machine in the same embodiment, and Fig. 7 is a front view showing a filter mounting portion of the drum type washing machine i in the same embodiment. As shown in Figs. 2 and 6, the filter 32 of the water suction portion 33 10 forms a covering space 41 larger than the water suction port 39 to cover the water suction port 39, and the water suction port 39 is opened to the water suction portion 33 and connected to the water suction side. Path 31a ' Therefore, the filter 32 cooperates with the inner covering space 41 to ensure a water-passing area larger than the water absorbing opening 39, and the entire water-passing area passes through the covering space 41 to the water absorbing port 39' and is in the water-passing field. The portion larger than the water suction port 39 15 is not easily blocked by the mesh when the water is passed. At the same time, it is further advantageous to combine the flushing of the water flow generated in the water tank to suppress the pressure loss caused by the clogging of the mesh, and to easily ensure the predetermined flow rate in the circulation, which is suitable for the water suction portion 33. The total opening area of the filter 32 is set to be larger than the opening area of the water suction port 39, whereby the opening area of the filter 32 which is larger than the water absorption port can be read and secured to be larger than the opening area of the water suction port 39. The total opening area prevents the clogging of the mesh and further reduces the water passing resistance, so that the water passing area of the filter 32 larger than the water absorbing Q39 can be effectively utilized to ensure the total opening area larger than the opening area of the suction opening 39 to prevent The mesh is clogged and the pressure loss is further reduced. 19 201002902 The machine is too embarrassing, such as the exclusive distribution of 3 ", if the outlet is located in front of the washing machine body 2, then the washing machine's temporary, sub-cosmetic installation may be In contrast, in the present embodiment, the _transition unit 32 faces or is exposed in the water tank 3 due to the child's accident or the user's carelessness being easily touched and impaired.

The heater 71 can be attached and detached in the same manner as the transition unit 32. Further, the heater 71 can be provided with a dedicated heater attachment and discharge port different from the filter attachment opening 42 and can be attached or detached from the outside of the water tank 3. Further, as shown in Fig. 2, when the heater 71 is disposed in the recess 32d' on the inner side of the filter 32, it can be attached and detached simultaneously with the filter 32. However, it is necessary to have the following measures, that is, in the filter An electrical connection portion is provided in the mounting position of 32, and the electrical connection portion has an insulating structure with a power supply portion provided outside the water tank 3. 2, as will be described in detail in the present embodiment, as shown in the second, sixth, and seventh diagrams, the 'over-clamp 32 includes: the insertion portion 32a' is inserted into the covering space 41 via the skirting opening 42; The edge portion 32b is for sealing the loading and unloading port 42 when the insertion of the covering space 41 is completed. The flange portion 32b has a sealing member 47 which is close to or abuts 22 201002902 in front of the opening of the loading and unloading opening 42 and seals the loading and unloading opening 42 when the filter 32 is inserted into the covering space 41. Further, by the hole forming by the forming die, the filter 32 is formed in the insertion portion 32a, and the front portion of the flange portion 32b is formed with the picking portion 32 (which is easily detachable. With this configuration, The fitting pressure or the mounting pressure acts on the seal 5 member 47, and the filter loading and unloading port 42 can be easily and surely sealed between the filter 32 and the filter 32 installed through the filter loading and unloading port 42, and no special need is required. Operation 'and prevent water leakage caused by the filter loading and unloading structure. f Further, in order to prevent inadvertent insertion slack or seal slack caused by vibration of the water tank 3, as shown in Fig. 2, the setting is useful to occupy by screws The flange portion 32b is screwed to the mounting hole 49 on the side of the water tank 3. Further, the finger-in portion 32a has a projecting portion 32a1 which is attached to the covering space 41 of the lower filter 32 and the water tank 3 at the end of insertion. When the opening 41a is in a close fitting state, a predetermined amount is discharged in the water tank 3 or a predetermined exposed state is formed. Further, the insertion portion 32a is lower than the flange portion 32b of the protruding portion 32a, and is 15 lower than the protruding portion. 32al and toward the insertion side, ie The back side of the clothes machine body 2 constitutes a "longitudinal wedge-shaped positioning flange 32a2 integrally formed in the protruding portion 32al. The flange portion 32a2 is guided by the guiding groove 41b, and the guiding groove 41b is It is formed under the edge of the opening 41a of the covering space 41 of the water tank 3, and is wedge-shaped in side view, whereby the insertion portion 32a can be easily and surely inserted into the predetermined insertion end position and fixed to a predetermined position. In the present invention, the front view, the cross-sectional view, and the longitudinal cross-sectional view of the connecting water circulation path and the discharge side path of the drum type washing machine in the present embodiment are shown in Figs. 9A to 9C. As shown in FIGS. 9A to 9C, the discharge side path 31b of the water circulation path 31 is connected to the discharge port 51 from the outside, and the discharge port 51 23 201002902 is provided at the lowermost portion of the opening 13 of the water tank 3 and the front end wall 3h. In this case, the circulating water from the discharge side path is sprayed between the inner surface of the front end wall 3h of the front side of the water tank 3 and the front end wall 4b of the rotating drum 4 corresponding thereto, and is discharged to the rotary drum 4 via the flow path 52 formed in the space. If by this structure, Then, since the discharge port of the water from the discharge side through 3 lb is located at a position that does not come into contact with the washing material in the rotary drum 4, it is possible to prevent the washing material from being caught in the laundry, washing or drying, and the like. The necessary action is disturbed, or the laundry is damaged or damaged. At the same time, since the flow path 52 is formed between the front wall 3h and the front end wall of the water tank 3 and the rotary drum 4, no special parts are required, and 10 使用 is used. The structure of the sealing member 56 is simple and inexpensive, and reduces the risk of water leakage. By the action of the laundry which is replaced up and down in the forward and reverse continuous rotation driving mode, and the movement of the laundry which is replaced by the right and left in the forward and reverse arc rotation driving mode The combination 'can further improve the jetting effect of the circulating water. Further, 'the discharge port 51 is attached to the inner surface of the front end wall 3h 15 of the water tank 3 as shown in Fig. 9C, and is opened toward the center of rotation of the rotary drum 4, specifically, the front end wall 3h toward the water tank 3 and the rotary drum 4, The annular outlet 53 in the flow path 52 between the front end walls 4b is opened, so that the circulating water sprayed from the injection port 51 can be efficiently discharged to the flow path 52 toward the rotation center side of the rotary drum 4, specifically, the ring can be turned toward the ring The outlet port 53 is efficiently discharged to the inner side of the rotary drum 4 in the radial direction, so that the circulating water can be efficiently supplied regardless of the amount of laundry. The front end wall 3h of the water tank 3 has an inclined surface 3hl and a curved surface 3h2, and the inclined surface 3hl is inclined from the position corresponding to the discharge port 51 toward the rear side of the washing machine body 2 from the vicinity of the inner circumference, and the curved surface 3h2 is on the inclined surface 3hl to The inner circumference is curved toward the opening side of the rotary drum 4. By having the inclined surface flap 1 and the end surface 3h of the 24 201002902 before the curved surface 3h2, as shown by the solid arrow symbol in FIG. 9C, the circulating water sprayed to the flow path 52 can be discharged from the inclined surface 3hl along the curved surface 3h2. The machine 1' can discharge the circulating water discharged to the flow path 52 through the opening of the rotary drum 4 toward the inside of the rotary cylinder 4, thereby improving the supply efficiency of the circulating water to the laundry. Here, as shown in Figs. 9A to 9C, the (four) port 51 has a connection port 51a formed in the front end wall 3h of the water tank 3, and the discharge port 51 is configured to eject the circulating water from the connection port 5la of the connection discharge side path 31b. To the flow path 52. The discharge port η opens to the flow path 2 in a predetermined range in the circumferential direction toward the rotation center side of the rotary drum 4, and accordingly, in order to provide the connection port Ha to the front end of the water tank 3, the nozzle outlet 51 opening toward the flow path 52 is formed. Thereby, the circulating water from the discharge-side path 31b can be guided to the flow path 52 side via the discharge port 51 without being disturbed, and the annular outlet 53 corresponds to a predetermined area of the circumferential direction of the discharge port 51, with The inside of the rotating drum* is discharged stably in the predetermined direction toward the left and right, and therefore, the circulating water can be efficiently supplied to the laundry in the rotary drum 4 regardless of the amount thereof. Further, the discharge port 51 is formed between the connection end portion 55d connected to the discharge side path 131b of the connection port 51a, and guides the circulating water to the opening toward the flow path 52, thereby being provided on the connection discharge side path 311. In order to guide the circulating water to the side of the flow path 52, the discharge port 51 of the connection port 51a can be configured by a simple mutual shape in which the connection and the portion 55d cooperate. With such a simple structure, the discharge flow is large in the circumferential direction, the discharge flow thickness is sufficient in the front-rear direction, the discharge flow velocity at which the water distance can be increased, and the like, and the laundry can be appropriately carried out regardless of the number of laundry The supply of circulating water. Moreover, the piping structure will not be particularly complicated and will not increase the risk of water leakage, nor will it become a cost increase. Further, as shown in Figs. 9A to 9C, the discharge port 51 is opened at a substantially central position at the bottom of the front end wall 3h of the water tank 3, and the discharge port 51 is connected by the resin conduit 55 shown in Figs. 4 and 9Ai9c. Spit side path 3ib. The duct 5 55 is formed by combining the two front and rear members 55a and 55b so as to be flat in front and rear, and the discharge side path 31b is disposed to be biased in the left-right direction with respect to the opening position of the discharge port 51, and the self-circulating pump 20 It extends forward in parallel with the axis of the water tank 3. The duct 55 is connected to the discharge port 51 at the front end of the tubular discharge side path 3ib, that is, the connection pipe 1? 55c integrally formed at the end of the rear member 55b is connected to the discharge side path 31b to form an extension portion thereof. The front member 55a extends substantially horizontally from one end side of the rear member 55b to the vicinity of the lower side of the discharge port 51, and then is bent and raised to the discharge port 51 to form a connection end portion 55d as shown in Fig. 9C at the connection end portion. The 55d is formed with a joint port 55e integrally formed with the rear member, and the joint port 55e is transmitted through the joint member of the front end wall opening of the water tank 3 15 through the seal member %, and is screwed by a screw 57. Accordingly, the duct 55 is formed as a flat front and rear, and the duct 55 is connected from the outer end 55d of the connection port 5la of the water tank 3 to the outer side of the water tank 3 and is connected to the circulation pump 2〇. The side is connected, whereby the front wall 3h of the water tank 3 and the front wall surface of the washing machine body 2 can be equipped with 20 tubes by a small space. Further, by the flat shape of the guide 55, the circulating water can be rectified into a water flow width and a water flow commensurate with the opening of the discharge port 51, etc., whereby the circulating water can be ejected from the connection port 51a toward the discharge port 51 to the flow. The road 52 satisfies the discharge width in the large circumferential direction from the annular outlet 53, the discharge thickness in the front-rear direction, and the discharge speed in which the water distance can be increased, and the flow is not disturbed, and the result is 26 201002902. Further improve the laundry and washing effect. Further, the duct 55 is connected to the connection port 51a by the rising portion, and the rising portion extends from the outer circumference of the water tank 3 to the lower side of the connection port 51a of the discharge port 51 at the lower portion of the front end wall 3h, and is bent from there. Since it is connected to the connection port, the circulating water that has been rectified into a flat flow is not disturbed by the curved shape of the rising portion, and can be guided to the connection port 51a and the discharge port 51' having the same flat direction and ejected to the flow. Since the circumference of the road is in the predetermined area, it is possible to spit out more stably from the wider area of the annular outlet 53, and to increase the effect of the circulating water on the laundry. In particular, the discharge port 51 is formed by the barrier wall 5c so as to open toward the annular outlet 53 between the upper edge of the connection port 10 51a, and the barrier wall is attached to the opening of the front end wall 3h of the water tank 3. 51a is formed integrally with the end wall 4b side of the rotating drum 4 at a right angle thereto. The connection end portion 55d is provided between the barrier wall 5c and the reduction port 55f' which smoothly smoothes the discharge passage from the duct 55 side by the R surface toward the discharge port 51, thereby assisting the circulation of water from the duct 55 toward the discharge port 15. The flow is made to flow along the inclined surface I 3hl and the curved surface 3h2 of the inner surface of the front end wall 3h of the water tank 3 in a strong manner. Therefore, the circulating water can be determined by a predetermined path toward the upper side of the rotating drum. The spouting and extending to the left and right and drawing a longer flow path of the parabola, the laundry supplied to the rotating drum 4 from a wider area, however, the narrowing path for making the high-speed flow can be connected to the guide tube 55 55 The connection end portion 55d of the interface 51a is arbitrarily formed between the discharge port 51, that is, the circulating water that has flowed through the discharge port 51 provided in the connection port 51a is guided to the flow path 52 side. In this case, the discharge flow width in the circumferential direction and the discharge flow thickness in the front-rear direction can be increased by the simple shape of the connection between the discharge end path and the connection end 55d of the connection port 51. 27 201002902 The discharge speed of the water distance, etc., regardless of the number of washings, to meet the guidance of appropriate conditions. Moreover, the piping structure is not particularly complicated and does not increase the risk of water leakage, nor does it become a cause of cost increase. Further, as shown in Fig. 9C, the end wall is formed in the circumferential rib 14 in the circumferential direction 5 and the annular rib-like projection 4c is formed in the circumferential direction 5, and the rib-like projection 4c is formed to be inclined with the inclined surface 3hl. Leave a narrow gap S between them. Further, the rib-like convex portion 4c is changed in a fluctuating manner in the upward direction. Therefore, the rib-like convex portion 4c is rotated when the square-turning drum 4 is rotated, as shown in FIG. 9C at three specific positions (solid line) And the dotted line), the cross-cutting position of the flow path 52 near the discharge port 51, that is, the position at which the narrowing S is narrowed, is displaced in the radial direction, and as a result, the circulating water flow toward the %-shaped outlet 53 in the flow path 52. There is a case where the vicinity of the annular outlet 53 is narrowed by narrowing the gap s, and a position away from the annular outlet 53 is reduced to a narrowing gap S, whereby the angle of the circulating water toward the inside of the rotary drum 4 is up and down. Since it is deflected, it is possible to separate the circulating water in the wide area 15 of the direction of the axis of the rotary drum 4 and supply it to the laundry. Here, the rib-like convex portion 4c is disposed on the side wall of the end surface of the rotary drum 4 so as to be unevenly discharged in the circumferential direction, so that the discharge is discharged to the flow path 52 and discharged from the annular outlet 53 to the rotary drum. The discharge direction of the circulating water in 4 is disturbed or changed after the month 'J, so that the discharged circulating water is disturbed or changed before and after the position of the washing water in the rotating drum 4. Such a discharge guide can be formed as an inner circumference that fluctuates in the circumferential direction, a wall surface that oscillates back and forth in the circumferential direction, a side that protrudes toward the flow path side and fluctuates in the circumferential direction, or an intermittent rib-like projection 4 or a blade. At least one of the obstacles for the passage of the circulating water sprayed by the flow path in the circumferential direction is disturbed or changed by the front and rear of the discharge direction 28 201002902, and can be compounded as much as possible use. By the parabolic supply action and the separation function before and after, the circulating water can act on the laundry, and it is not biased in the front-rear direction, and the dissolution effect, the laundry effect, and the washing effect of the lotion are improved. Further, as shown in Figs. 3 and 4, a baffle 61 for preventing the suction of the laundry is provided at a position directly above the drain port 36.

20 As described above, according to the present invention, it is possible to provide a drum type washing machine in which a rectangular wire bottomed cylinder (four) drum is disposed in a water tank, so that a front side of the opening is formed as a rotating shaft from the front side of the opening. The direction is horizontally or inclined downward from the horizontal direction, and at least one of a washing program and a washing program is performed by the motor driving the rotating drum. The washing machine includes a water circulation mechanism through a circulation path connected to the water tank. The circulation pump is used to circulate the water in the water tank. In addition, the circulation mechanism has a secret, that is, the secret is placed between the end wall surfaces of the rotating drum before the cutting material is turned, and the circulating water is spit out to the rotation and the tube. In the structure, as long as the circulation path is connected with: the groove=wall, the circulation path can be connected with the flow paths formed in the water tank and the rotating drum. Therefore, the water circulation mechanism is used in the laundry process or In the case of the cleaning process, etc., when the suction rod is sucked into the water tank and circulated, there is no need for a special distribution, and the water in the crucible is formed in the space between the front end walls. = Y may be part of the flow via said] <% shaped outlet, you ring according to the water discharged into the rotary drum. Moreover, the flow path between the front end walls of the water ring cylinder is discharged from the inner peripheral portion of the front end wall == the mouth, so that it is not necessary to have the special shape of the polyester material stuck in the rotating drum. The spit can be spit out. Further, according to the present invention, the water-passing connection from the discharge side path of the circulation pump and the connection port of the sputum are discharged from the connection port to the flow path, and the π' system is sprayed. The rotation center side is in a predetermined range in the circumferential direction in the rotation cylinder in such a configuration, and by forming the opening toward the flow path: the circulating water from the discharge side path can be disturbed by the mouth exit, σ, Therefore, it is possible to guide from the annular direction to the flow path side without the garment-like outlet corresponding to the predetermined area of the discharge, with the predetermined direction toward the left-right direction field 10 to the rotary drum. In addition, according to the present invention, the discharge port can be connected to the end of the connection path connecting the outlet side path, and the circulating water spouting head is directed toward the flow path. The outlet of the spray 15 disposed at the connection port connecting the discharge side path further guides the circulating water to the flow path side, and can be arranged by a mutually simple shape coordination structure which cooperates with the connection end portion of the discharge side path and the connection port. achieve. Furthermore, according to the present invention, the discharge side path has a duct connected to the circulation pump side from the outer periphery of the water tank from the connection end portion, and the duct is flattened front and rear, and is formed toward the discharge port toward the discharge port. The opening position of the flow path is reduced, and the narrowing path of the circulating water is ejected. According to this configuration, the duct is further flattened front and rear, whereby the discharge side path can reduce the necessary piping space of the duct between the front end wall of the water tank and the front wall of the washing machine body. In addition, 'the circulating water toward the connection port and the discharge port can be rectified into a wide flow parallel to the expansion direction of the flow path between the front end walls and flat 30 201002902, and then the circulating water guide can be taken from the connection port and the discharge port. The flow path is led to the direction in which the flat direction is aligned with the circumferential direction, and is discharged into the rotary drum from an annular outlet that is also in the same flat direction. Furthermore, according to the present invention, the connection port of the discharge port is located at the lower portion of the front end wall of the water tank, and the duct has an ascending portion and is connected to the connection port of the discharge port, and the rise portion extends laterally from the outer circumferential position of the water tank. After being near the lower side of the connection port of the discharge port, it is bent and raised to the connection port of the discharge port. In this configuration, after the circulating water is rectified into a flat flow and guided to the lateral direction, it is not disturbed by the curved shape of the rising portion, and 10 can be guided to the connection port. Inflow, and then, in a wide flat flow state, the discharge port between the flat ends and the flow paths between the front end walls can be more stably discharged from the wider annular outlet. Further, according to the present invention, the flow path is formed by an annular outlet formed between the water tank and the front end wall of the rotary drum, and the discharged circulating water is discharged obliquely upward toward the rear of the rotary drum. In such a configuration, the discharge circulating water from the annular outlet can obtain a long path of a high parabola obliquely upward from the inside of the rotary drum, and increase the spread to the left and right.
