Description

200403374 (1) 发明. Description of the invention [Technical field to which the invention belongs] The present invention relates to a drum (which is rotatably arranged in a horizontal axis state in a water tank arranged in an outer box and stores laundry inside) ( d ru m), which is a drum-type washing machine having a buffle disposed on an inner peripheral surface thereof along an axial direction.

[Previous Technology] In recent years, drum-type washing machines have gradually become popular. The drum type washing machine has the advantages that it can be washed with a small amount of water, and has less damage to the laundry, and is also suitable for drying operation compared with the conventional vertical full-automatic washing machine.

When using a vertical full-automatic washing machine for washing, it is unavoidable to generate lint caused by slight damage to the laundry, and a filter must be provided to capture the lint. On the other hand, in the drum type washing machine, since there is very little damage to the laundry, the necessity of installing an over-cutter for thread shavings is low. In addition, there are also reasons why it is not easy to install a filter in the drum-type washing machine. [Summary of the Invention] [Problems to be Solved by the Invention] However, even if there are few thread shavings directly generated by the laundry, there are often cases where, for example, the tissue tissue or business card is forgotten to be taken out of a clothes pocket. Rinse in the state. Or, when raising dogs in the house-6- (2) (2) 200403374 or cats, their hair is often attached to clothing, etc. Therefore, since it can be fully assumed that these will form floating matter during washing, it is still better to use a filter for trapping. In response to such a prior art, for example, in Japanese Patent Application Laid-Open No. 8-4 7 5 9 3, it is disclosed that a partition plate that is disposed on the inner peripheral portion of the drum and locks the laundry during rotation and moves in the rotation direction is disclosed. Drum-type washing machine provided with a dishwasher. However, with a filter of such a simple structure, it can be seen that on the one hand, the collected thread shavings cannot be retained and released into the water again, and the actual filtering effect has to be questioned. In addition, in order to fully obtain the so-called "batter washing" washing effect in the water level of the drum type washing machine, setting a low water level may cause problems such as thread shavings adhering to the laundry being difficult to escape. The present invention has been developed in view of the foregoing circumstances, and an object thereof is to provide a drum-type washing machine which can further improve the collection effect of thread shavings and the like. [Means to Solve the Problems] In order to achieve the above-mentioned object, the drum-type washing machine according to the first aspect of the present invention includes: a water tank disposed in an outer box; and the water tank is rotatably disposed in a horizontal axis state in the water tank. A drum for storing laundry inside; a partition plate arranged along the axial direction on the inner peripheral surface of the drum; and a box-shaped filter arranged inside the partition plate; the filter is located in the rotation direction of the drum; Each of the two filtering surfaces has a plurality of openings with different sizes. (3) (3) 200403374 According to this structure, when the drum rotates in the direction of the filtering surface provided with a large opening portion among the two filtering surfaces of the filter arranged inside the partition, Line debris and the like are trapped inside the filter through the opening. Then, when the rotation direction of the drum is reversed, because the opening of the filtering surface is small, although the effect of trapping the line debris and the like is relatively small, the line debris and the like once captured will not be released to the filter again. Device outside. Therefore, in general, it is possible to improve the collection efficiency of wire chips and the like. The drum-type washing machine according to the second aspect of the present invention includes: a water tank arranged in the outer box; and the water tank is rotatably arranged in a horizontal axis state, and the laundry is accommodated inside, and the rotating shaft is provided for the laundry. A drum inclined downward in the input direction; a partition plate arranged on the inner peripheral surface of the roller along the axial direction; and a box-shaped filter arranged inside the partition plate, the filter is located in the rotation direction of the roller The two filtering surfaces each have a plurality of openings of different sizes. The opening area of the opening located on the deep side of the laundry in the feeding direction is smaller than the opening area of the opening located on the front side in the feeding direction. That is, in a washing machine in which the rotation axis is inclined in order to make it easy for a user to take out and insert laundry into and out of the drum, the filter is disposed when the filter disposed inside the partition is on the lower side. It is formed to be inclined to the water surface, that is, the water is immersed in a state where the front side is shallow and the deep side is deep in the washing direction. Therefore, on the filter surface, if the opening area of the opening on the deep side of the input direction is made small, when the drum rotates, the water level (4) (4) 200403374 rises to the front of the filter through the water level. The swarf and the like collected by the large opening part move toward the deep side of the passing device while the water level drops. Therefore, in the same manner as in the first invention, the collected wire chips and the like are not released to the outside of the filter again, and the collection efficiency of the wire chips and the like can be improved. The drum-type washing machine according to the third aspect of the present invention includes: a water tank arranged in an outer box; a drum arranged rotatably in a horizontal axis state in the water tank, and containing a laundry therein; A partition plate whose inner peripheral surface is arranged along the axial direction; and a box-shaped filter arranged inside the partition plate, the water level in the drum during washing operation is set higher than the water level during washing operation. Generally, a drum type washing machine is characterized by being capable of washing with a smaller amount of water than a vertical type washing machine. However, when it is estimated that the thread shavings and the like are collected by a filter, the water level in the drum can be made high to easily release the thread shavings and the like attached to the laundry. The cleaning operation of the drum type washing machine does not reduce the cleaning effect even if the water level in the drum is increased. Therefore, according to such a configuration, it is possible to improve the collection effect of the wire chips and the like during the cleaning operation during the cleaning operation. In this case, as described in the invention 4, the aforementioned filter is formed such that the opening areas of the openings provided on the two filtering surfaces are different, respectively. According to such a structure, the same effects as those of the first invention can be obtained in the third invention. In this case, as described in the invention 5, the rotation direction of the roll (5) (5) 200403374 during the washing operation is preferably formed in one direction of the opening portion having a large area where the filter is arranged. According to this structure, 'the cleaning operation' can collect more thread chips and the like from the large opening side of the filtering surface. In this case, as described in the invention 6, after washing and rotating the rotating direction of the drum as one direction, the water level in the drum is lowered, and the rotating direction of the drum is alternately positively reversed, and then the washing is performed. Rotation is better. That is, as described in the invention 5, if the rotation direction of the drum is continuously washed and rotated, the laundry may be entangled with each other. Therefore, the water level can be lowered and the drum can be lowered thereafter. The normal and reverse rotation of the rotation direction is performed in normal washing operation to prevent knotting of the cloth. Further, as described in the invention 7, the washing operation performed after the water level in the drum is changed from the water level during the laundry operation can be selectively performed. That is, in the judgment of the user (), it is possible to selectively perform the same washing operation as usual when it is desired to save the amount of water used preferentially than to use a filter to collect thread shavings. In the above case, as described in the invention 8, it is preferable that a mesh having a filtering function is formed in the partition. According to this structure, it is possible to obtain a filtering effect by using the sieve holes provided in the partition plate at a stage before the filter is used to collect the swarf and the like. In addition, as described in the invention 9, it is preferable that the cross-sectional shape of the separator in the radial direction is set to a position where the filter is mounted in a non-paired state. In other words, when the partition is placed in the filter, it is best to ensure a large filtering surface area in order to obtain a good filtering effect. Therefore, the filter is located at the approximate center and the maximum height dimension of the filter Just agree. -10- (6) 200403374 On the other hand, in order to fix the partition to the inner peripheral surface of the drum, it is necessary to form a mechanism portion that fixes the outer peripheral side of the drum on the inner portion of the partition. In addition, if the radial cross-sectional shape of the partition plate is made asymmetrical to the mounting position of the ballast, the above-mentioned mechanism portion can be satisfied at the same time by displacing and disposing the mechanism portion from the mounting position.

Further, as described in the invention 10, it is preferable that the filter is configured to be detachable to the partition, and it is preferable that the operation unit for performing the detachment is provided on the front side of the laundry feeding direction. According to this structure, the user can operate the operation portion on the front side in the insertion direction, and the filter can be easily removed from the partition to perform sweeping and the like. Further, as described in the invention 11, it is preferable that the filter has a hinge and the main body can be opened and closed. According to this structure, it is possible to easily remove the wire debris and the like trapped inside the filter.

Further, as described in the inventions 12 and 13, the filter is attached and detached from the upper surface side of the partition, and when the filter is attached and detached, the upper surface of the partition is preferably blocked. With this structure, it is possible to prevent the swarf and the like captured by the filter from being released from the upper face. In addition, as described in the invention 14, the partition is preferably arranged in accordance with the position of the convex portion formed on the back surface of the drum for reinforcement. In other words, the convex portion also performs the same function as the separator and the laundry on the back side of the drum, so that the washing effect can be further enhanced. In addition, the convex portion has a function of agitating water when the drum is rotated, and the agitated water easily flows into the filter along the partition. Therefore, it also has the effect of improving the collection effect of the swarf and the like using the filter. -11-(7) (7) 200403374 [Embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. First, FIG. 5 shows the overall structure of the drum type washing machine. A door 2 is provided at a central portion of the front portion of the casing 1 outside the casing of the drum type washing machine. This door 2 is a door for opening and closing the laundry taking-out inlet 4 formed in the central portion of the front portion of the outer case 1. A cylindrical water tank 5 is arranged inside the outer box 1. This water tank 05 has a horizontal axis shape whose front-to-rear direction (left-right direction in Fig. 5) is formed in the axial direction, and is arranged to be inclined in a front-rising manner, and is elastically supported by the elastic support device 6. Inside the water tank 5, a cylindrical drum 7 and the water tank 5 are arranged coaxially. This drum 7 is a person who functions as a tank for dehydration and drying in addition to washing monkeys. A large number of small holes 8 (only a part of the figure) are formed in almost the entire area of the body. Zhou Ye is provided with three partitions 9 at intervals of 120 degrees, for example (refer to FIG. 6; only one is shown in FIG. 5). Lu Zai, as shown in FIG. 6, on the back surface of the drum 7, a convex portion 7a for mounting a reinforcing member (not shown) on the inner surface side thereof is radiated radially from the center of rotation to the circumferential direction. The three spacers 9 are formed at intervals, and are arranged in accordance with the positions of the convex portions 7 a. That is, since the convex portion 7a is also locked to the laundry located on the back side of the drum 7 and moves in the rotation direction of the drum 7, it has the same function as the partition plate 9. In addition, only by forming the convex portion 7a, it is possible to structurally form the role of the reinforcing drum 7. The water tank 5 and the drum 7 have openings 10 and 11 for removing and inserting laundry in the front part. (8) 200403374. The opening 10 of the water tank 5 is made of bellows 12 watertight. It is ground-connected to the laundry inlet / outlet 4 and the opening 11 of the drum 7 is the opening 10 facing the water tank 5. A balance ring 13 is provided around the opening 11 of the drum 7.

A motor 1 4 for rotatingly driving the drum 7 is disposed on the rear surface of the water tank 5. In this case, the motor 14 is an outer rotor type DC brushless motor, and a stator 15 thereof is mounted on a bearing housing provided at a central portion of the cover portion of the water tank 5 ( bearingh 〇using) 1 6 outer periphery. The rotor 17 (rot o tor) is arranged so as to cover the stator 15 from the outside, and a rotating shaft 18 mounted at the center is rotatably supported by the bearing housing 16 through the shaft 19. The front end of the rotating shaft 18 protruding from the bearing housing 16 is a central portion connected to the back of the roller 7. Therefore, in this case, when the rotor 17 of the motor 14 is rotated, the drum 7 and the rotor 17 are rotated together.

A water storage unit 20 is provided on the lower portion of the water tank 5, and a heater 2 for heating washing water is disposed inside the water storage unit 20. A drain valve 22 is provided at the rear of the water storage unit 20. A drain hose 2 3 0 is connected to the upper part of the water tank 5, and a warm air generating device 24 is provided. A heat exchanger 25 is provided on the back of the water tank 5. The warm air generating device 24 includes a warm air heater 27 arranged in a case 26, a fan 29 arranged in a casing 28, and a belt. The fan mechanism (3 1 -13- 200403374 〇) of the driving mechanism 30 is configured to rotate and drive the fan 29, and the box 26 and the sleeve 28 are in communication. A duct 32 is connected to the front portion of the box 26. The front end portion of the duct 32 projects from the front portion in the water tank 5 and faces the opening portion 12 of the drum 7. Here, warm air is generated by the warm air heater 27 and the fan 29, and the warm air is supplied into the drum 7 through the duct 32. The warm air supplied into the drum 7 is used to heat the laundry in the drum 7 and to extract moisture, and the water is discharged to the heat exchanger 25 side. The heat exchanger 25 communicates with the casing 28 at the upper portion and communicates with the water tank 5 at the lower portion. This heat exchanger 25 is a water-cooled type that uses water injected from the upper part and flows down to cool and condense the water vapor in the air passing through the interior, and then dehumidifies it. The air passing through the heat exchanger 25 is returned to the warm-air generating device 24 again, and is circulated after being warm-weathered. One of the three partition plates 9 (indicated by the partition plate 9 A) disposed inside the drum 7 is detachably mounted with a filter 50 for collecting strands and the like. Fig. 1 (a) is a perspective view showing a state where the filter 50 is mounted on the partition plate 9A; Figs. 1 (b) and (c) are oblique views showing the filter 50 and the partition plate 9 A in a separated state, respectively. Illustration. The partition plate 9A has a substantially trapezoidal cross-section in the radial direction (see FIG. 3 (b)), and an insertion portion 51 for inserting the filter 50 is formed in a central portion in the axial direction. On the other hand, the filter 50 is formed in a box shape elongated in the axial direction, and its two side surfaces (for example, the left and right sides in FIG. 5 that are the surfaces in the rotation direction side of the drum 7) form the filter surfaces 5 2 A, 5 2 B. On the front side (opening 1 1) of the filter 50 in the axial direction, a filter 50 is formed when a user mainly removes the filter 50 from the partition 9A with a finger. -14- (10) (10) 200403374 The operation part 5 3 used is extended to the upper surface part 5 4. On the other hand, a hinge 55 is formed at the end on the deep side of the filter 50 in the axial direction. As shown in FIG. 1 (d), the two filter surfaces 52A and 52B can be opened from the front side to the left and right. Figures 2 (a) and (b) show the filter surfaces 52A and 52B, respectively. The filter surface 5 2B is formed with a plurality of small openings 56 having a rectangular shape with a side of about 1 to 3 mm. The filter surface 2A 'is formed with a plurality of large openings 5 7 having a side of about 5 to 10 mm at about 3/4 from the front side to the deep side or about 2/3 from the upper side to the bottom side. Further, a small opening portion 56 is formed in the remaining portion similarly to the filtering surface 5 2B. In the partition plate 9 A, when the filter 50 is installed, sieve holes 58 having the same size as the large opening portion 57 are formed on the side of the position where the filter surfaces 52 A and 52B are located. FIG. 3 (a) is a bottom view showing the partition plate 9A, and FIG. 3 (b) is an A-B cross-sectional view showing (a). When the filter 50 is installed in the partition plate 9A, in order to obtain a good effect, it is better to ensure the areas of the large filter surfaces 52A and 52B as much as possible. Therefore, the spacer 50 is disposed at a position slightly in the center thereof in accordance with the maximum height dimension of the partition plate 9A. On the other hand, the partition plate 9A is fixed to the inner peripheral surface of the drum 7, and the claw 59 formed on the hem portion of the partition plate 9A is fitted into a fitting portion (not shown) provided on the roller 7 side, and the partition plate 9A It is effective to screw the outer peripheral side of the drum 7 after forming the hub part 60 in the vicinity of the central part. In order to meet these requirements, the spacer 9A is formed at a position shifted from the center by avoiding the position where the screw fixing hub portion 60 is inserted into the spacer 9A (left in the third figure -15- (11) 200403374 to). As a result, the cross-sectional shape of the partition plate 9 A is asymmetric in the left-right direction.

With the above-mentioned structure, the filter 50 is mounted on the partition plate 9A, and it is possible to collect the wire chips and the like floating in the water by the following actions. As shown in FIG. 4 (a), when the rotation direction of the drum 7 forms the filtering surface 5 2 A side of the filter 50, the thread shavings are collected by the filter 5 through the large opening 57. Then, if the partition 9A is moved to lower the water level inside the filter 50, the thread cuttings are moved toward the bottom of the filter 50 in which the small opening portion 56 is formed. On the other hand, when the rotation direction of the drum 7 is reversed, it becomes difficult to obtain the filtering effect of the filter 5 'but' it is possible to prevent the caught wire scraps from being released to the filter 5 during the forward rotation 0 outside.

In addition, since the drum 7 is inclined downward toward the deep side in the axial direction, the water level (for example, L i, L2 and the like shown in FIG. 5) injected into the drum 7 by the partition plate 9 A, and the filter 5 0 It is in a state of being submerged deeper on the deep side end side. Therefore, when the drum 7 rotates and the water level rises, the thread shavings that have been trapped inside the filter 50 move only toward the deep side end side where the small opening portion 56 is formed while the water level drops. Improved the capture effect. On the other hand, Fig. 7 is a block diagram showing the electrical structure of the present invention. The control device 40 constituting the control means of the present invention includes a microcomputer. For this control device 40, various operation input sections 3 from the operation panel are inputted. 3. A water level sensor (sens 0) 4 1 which detects the water level in the water tank 5; and a motor 1 4 which detects the rotation of the drum 7. The speed of the rotation sensor 42 and other signals. Then, the control -16- (12) (12) 200403374 device 40 has: based on these signals and a program provided in advance, the motor I4 is controlled by an inverter circuit 43 and a drive circuit is passed through 44 to control the buzzer 45, the display part 3 4, the heater 2 for heating the washing water 1, the drain valve 22, the warm air heater 27 and the fan motor 31 of the warm air generating device 24, and the water supply Valves and other functions. Next, the operation of this embodiment will be described with reference to FIG. 8. FIG. 8 is a diagram for briefly explaining the washing, washing, and dewatering operation flow of the drum type washing machine. (A) shows the water level injected into the drum 7, and (b) shows the rotation speed and rotation direction of the drum 7. . These are controlled by the control device 40. The forward rotation is defined as the direction of the filter surface 52B and the reverse rotation is defined as the direction of the filter surface 5 2 A. The washing course described below is performed when the user selects the "line cutting mode", and when the above-mentioned course is not selected, the same washing course as in the past is performed. That is, since the amount of thread shavings generated in a drum-type washing machine is smaller than that of a vertical type washing machine, it is estimated that depending on the user or the type of laundry, the necessity of collecting thread shavings may not be felt. First, in (1) "laundry" operation, the water level is based on the amount of laundry, such as any of L1 to L3 (1 e v e 1), which is not shown in Figure 5. Then, the rotation speed of the drum 7 is 50 rpm, and the direction of rotation is to alternately repeat forward rotation and reverse rotation (for example, stop for 27 seconds after 27 seconds of rotation in the forward rotation, stop 3 seconds after 27 seconds of rotation in the reverse rotation, ... ). Secondly, in (2) "Dehydration 1" operation, the rotation speed is 1000 rpm, and the rotation direction -17- (13) (13) 200403374 is a forward rotation. Next, in (3) "washing 1" operation, in the case of a conventional drum-type washing machine, forward rotation and reverse rotation are repeated alternately at the same water level as the "washing" operation in (1). However, in this embodiment, In the first half of j minutes, the water level is greatly increased to L4 as shown in FIG. 5, the rotation speed is 50 rpm, and the rotation direction is reversed. That is, the drum type washing machine is generally characterized by being able to perform washing with a small amount of water compared to the vertical type washing machine. However, when the filter 50 is used to collect thread shavings, the higher the water level is, the more likely it is to adhere to the washing. Thread shavings, etc. are free. Then, in the washing operation of the drum type washing machine, even if the water level in the drum 7 is raised, the washing effect may not be reduced. In addition, the rotation direction is reversed only to rotate in the direction of the filtering surface 52A where the large opening portion 57 of the filter 50 is arranged. Wire scraps and the like are taken in by the large opening portion 57 and collected by the filter 50. However, because the drum 7 may be knotted when the drum 7 is continuously rotated in the 1 direction, the drainage is performed on the way, and the second 5 minutes are interactively performed at the same water level as the "washing" operation of (1) Repeat forward rotation and reverse rotation. Then, (4) "dehydration 2" and (5) "washing 2" are repeated in the same form as (2), (3), and then (6) "final dehydration" (same as (2)), End the journey until dehydration. In addition, the convex portion 7a formed on the rear surface of the drum 7 is capable of agitating water when the drum 7 rotates. Therefore, the water that has been agitated becomes easier to follow the position of the convex portion 7a. The formed partition plate 9A flows into the filter 50. Therefore, the -18- (14) (14) 200403374 trapping effect for improving the swarf of the filter 50 is also produced. As described above, according to the present embodiment, since line debris and the like are trapped inside the drum 7, the two filtering surfaces 52A and 52B each have a plurality of large openings 5 7 and small openings 56 that are filtered. The device 50 is arranged inside the partition plate 9 A. Therefore, it is possible to prevent the wire scraps and the like once collected from being put outside the filter 50 as much as possible, thereby improving the collection efficiency. In addition, since the small opening portion 56 is arranged on the deep side of the laundry loading direction of the passing surface 5 2 A, the relationship between the rotation angle of the drum 7 toward the deep side of the laundry loading direction and the downward relationship with the water level It can prevent the once collected wire debris and the like from being released to the outside of the filter 50 again, and further improve the collection efficiency. Moreover, since the water level in the drum 7 during the washing operation is set higher than that during the washing operation, it is possible to easily dislodge thread scraps and the like attached to the laundry, and improve the filter 50 during washing operation Collection efficiency of line debris. Then, since the rotation direction of the drum 7 during the washing operation is made one of the filtering surfaces 52A where the friend filter 50 is arranged, it is possible to use the large opening portion 5 7 of the passing surface 5 2 A during the washing operation. Capture more swarf and more. In addition, since the rotation direction of the drum 7 is changed to one direction to perform the washing operation, the water level in the drum 7 is lowered, and the rotation direction is reversed before the washing operation is performed. Therefore, the laundry can be prevented from being tangled Cause the cloth to become knotted. In addition, since the above-mentioned washing operation can be selectively performed, it is better to use a user's judgment than to use a filter 50 to collect thread shavings, etc. -19- (15) · (15) · 200403374 When the amount of water used is saved first, the same washing operation as usual can be selectively performed. In addition, since the sieve holes 5 8 having a filtering function are also formed in the partition plate 9 A, the filtering effect can be obtained with the partition plate 9 A before the stand filter 50 collects the swarf and the like. In addition, the radial cross-sectional shape of the partition plate 9 A is made asymmetrical with respect to the installation position of the filter 50, so that a good effect of using the filter 50 can be obtained, and the fixed partition plate 9A can be mounted on the drum 7. The mechanism portion for the inner peripheral surface is formed inside the partition plate 9A. φ In addition, the filter 50 is detachably attached to the partition 9A, and the operation portion 53 for performing the attachment and detachment is provided on the front side of the washing direction, so the user can easily place the filter 50 The separator 9A is removed for sweeping and the like. Further, since the filter 50 has a structure having a hinge 55 so that the main body can be opened and closed, it is easy to remove wire debris and the like trapped inside the filter 50. In addition, the filter 50 is configured to be attached and detached from the upper surface of the partition plate 9 A, and blocks the upper surface portion of the partition plate 9 A when the filter 50 is installed. Therefore, it is possible to prevent the line debris and the like trapped by the filter 50 from the upper surface Portion 54 is released. In addition, each partition plate 9 is disposed in cooperation with the position of a convex portion 7a formed on the rear surface of the drum 7 for reinforcement. That is, the convex portion 7a also exerts the same effect on the laundry on the back side of the drum 7 as the partition plate 9 ', so that the washing effect can be further enhanced. In addition, the effect of introducing the picked-up water into the filter 50 along the partition plate 9a by the convex portion is also formed, so that a trapping effect of improving the use of the filter chip 50 and the like is produced. Those limited to the embodiments described above and described in the drawings may also be deformed or expanded as described below. -20- (16) (16) 200403374 The opening portion of the filtering surface 52B may be formed in the same pattern as the filtering surface 52A. It is also possible to arrange only the large opening portion 5 7 on the filtering surface 5 2 A. The sieve holes 5 8 arranged in the partition plate 9 A can be set as required.
