It is configured to prevent the body 7 from sliding further forward.

  About the washing machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  Details of the operation by the laundry washing and drying program execution will be described below.

  First, an outline of the washing operation will be described. Laundry includes a washing step, a rinsing step, and a dehydrating step. In the washing process, first, the user pulls the handle 21a, slides the water tank 3 forward, and pulls it out. After the water tank 3 is pulled out, the water tank lid 6 is slid and opened in the circumferential direction of the water tank 3, and the drum lid 5 is slid and opened in the circumferential direction of the drum 2, and the laundry is stored in the drum 2. After storing the laundry, the user closes the drum lid 5 and the water tank lid 6, pushes the handle 21 a to store the water tank 3 in the housing 22, operates the operation buttons to select a desired operation program, To start.

  The control device 24 drives the motor 4 to determine the amount of laundry from the number of rotations. Thereafter, the control device 24 opens the water supply valve 14 to allow the faucet A and the water tank 3 to communicate with each other, and starts to accumulate water in the water tank 3. The water supplied to the water tank 3 through the water supply valve 14 passes through the detergent case, and supplies the detergent and the like in the detergent case into the water tank 3 together with the water. At this time, the drain pump 16 is in a stopped state. While storing water, the control device 24 drives the motor 4 to wet the laundry evenly.

  When a predetermined amount of water is stored in the water tank 3, the control device 24 closes the water supply valve 14 and rotates the drum 2 in accordance with a predetermined program such as normal rotation and reversal of the motor 4 to remove dirt from the laundry. When the predetermined time has elapsed, the control device 24 ends the washing process.

  When the washing process is completed, the process proceeds to a rinsing process. In the rinsing process, a series of rinsing operations including drainage, water supply, and motor drive are performed twice. In the first rinsing operation, first, the control device 24 drives the drain pump 16 to discharge the washing water from the water tank 3 together with the detergent and dirt. Next, when drainage is completed, the control device 24 stops the drainage pump 16, opens the water supply valve 14, makes the faucet A communicate with the water tank 3, and supplies water to the water tank 3 again. When a predetermined amount of water is supplied into the water tank 3, the water supply valve 14 is closed. With the water stored in the aquarium 3, the control device 24 drives the motor 4 to move the detergent components and dirt components adhering to the laundry into the unclean water and rinse to remove the dirt. When a predetermined time has passed, one rinsing operation is completed. During the water supply and rinsing, the drain pump 16 is controlled to be stopped.

  After repeating the above operation twice, the water in the water tank 3 is discharged and the rinsing process is completed.

  When drainage in the water tank 3 is completed and the rinsing process is completed, the dehydration process is performed next. The control device 24 drives the motor 4 to rotate the drum 2 at a high speed (for example, 1400 rpm). At this time, the centrifugal force applied to the laundry increases as the rotational speed increases, so that the laundry sticks to the inside of the drum 2. And the water | moisture content contained in the laundry is skipped inside the water tank 3 through the hole 2b of the drum 2 with a centrifugal force. In this way, moisture contained in the laundry is removed by centrifugal force.

  The dehydrated water is discharged from the water tank 3 when the control device 24 drives the drain pump 16. When dehydration is continued for a predetermined time, the control device 24 reduces the rotation of the motor 4, and when the magnetic force detection sensor 28 detects that the magnet 27 is closest, the rotation of the motor 4 is stopped and the fixing device 25 is operated. Then, the fixing pin 26 is inserted into the fixing hole 2d of the drum 2 to lock the drum 2 so as not to rotate.

  Next, the sliding operation of the slide structure 7 will be described.

  The control device 24 can fix the slide structure 7 to the housing 22 and make it non-slidable by a slide fixing solenoid (not shown). During operation, that is, when the motor 4 is driven and the drum 2 is rotating, or when the water supply valve 14 and the drainage pump 16 are operating, the control device 24 drives the slide fixing solenoid to slide The structure 7 is fixed so as not to slide. In a state of not operating, the control device 24 releases the slide fixing solenoid so that the slide is possible. In this case, the user can easily slide the water tank 3 by pulling the handle 21a, and the front wheel 17 of the slide structure 7 comes into contact with the front stopper 19 and stops. When the user pushes the handle 21a, the slide structure 7 slides backward, comes into contact with the rear stopper 20, and stops in the storage state of the water tank 3.

  In a conventional drum pull-out configuration, the state of washing is a state where water is contained in the aquarium. For example, in order to prevent the water in the aquarium from leaking even if trying to add laundry, The drum 2 cannot be pulled out and is unusable.

  If it is the structure of this Embodiment, since the water tank 3 is pulled out, the water leak from the water tank 3 will not arise even if it pulls out at any timing during washing.

  In the present embodiment, since the water tank 3 is supported by the slide structure 7 disposed in the washing machine main body 1, the water tank 3 is pulled out and there is no support below the drawn water tank 3. There are no marks or dents. In addition, since the front door 21 and the water tank 3 are positioned higher than the human ankle in the state in which the water tank 3 is pulled out, the foot does not come into contact with the front door 21 and the water tank 3 that are pulled out, and safety is high.

  As shown in FIGS. 1 and 2, the center of gravity B of the water tank 3 after dewatering when the laundry of the maximum capacity is put in the drum 2 is the front wheel 17 and the rear wheel 17 of the slide structure 7. Therefore, the water tank 3 can be smoothly slid and moved.

  On the other hand, the center of gravity C of the water tank 3 in a state where a predetermined amount of water is put in the water tank 3 is located further forward than the front wheel 17 of the slide structure 7. In this state, the slide structure 7 tends to fall forward with the water tank 3 and the wheel 17 on the front side of the slide structure 7 as a base point, and the rear upper portion 7b of the slide structure 7 is provided on the top surface of the housing 22. Touch the contact. Contact between the rear upper portion 7b of the slide structure 7 and the sliding contact portion of the top surface of the housing 22 is defined as contact resistance when the water tank 3 is slid.

  Thereby, in a state where a large amount of water has entered the water tank 3, the water tank 3 can be slowly pulled out by the contact resistance between the rear upper part 7 b of the slide structure 7 and the upper part of the inner surface of the housing 22. Therefore, even when the drum lid 5 is opened immediately after the water tank 3 is pulled out, the water in the water tank 3 does not jump out and spills on the surrounding floor. The contact resistance between the rear upper portion 7b of the slide structure 7 and the sliding contact portion at the upper portion of the inner surface of the housing 22 can be adjusted to be appropriate.

  For example, when the operation is stopped by pressing a pause button during washing, the control device 24 temporarily stops driving the motor 4 and the like. Thereafter, the motor 4 is driven again at a low rotation to lock the rotation of the drum 2, and then the slide fixing solenoid is released to display that it is in a temporarily stopped state.

  The control device 24 determines the presence / absence of water in the water tank 3 based on the operation history, particularly the operating conditions of the water supply valve 14 and the drainage pump 16, and controls the drawable range of the water tank 3.

  The control device 24 determines the presence or absence of water in the water tank as follows.

  The state where there is no water in the aquarium 3 is a state after the drain pump 16 has moved for a predetermined time, that is, a state where the washing water in the aquarium 3 is drained, or a state before the water supply valve 14 is opened, In a state where water is not contained in the water tank 3, the slide regulating device 29 is not driven and the water tank 3 can be drawn out.

  On the other hand, the state in which there is water in the water tank 3 is a state in which the drainage pump 16 is not driven for a predetermined time after the water supply valve 14 is opened, and the control device 24 drives the slide regulating device 29. The stopper 30 is projected into the locus of the slide structure 7 to restrict the slide movement of the slide structure 7 and prevent the forward movement from the position shown in FIG.

  The position of the aquarium 3 shown in FIG. 6 is a position where the drum 2 and the half of the opening of the aquarium 3 are exposed to the exposed position, the drum lid 5 and the aquarium lid 6 are opened, and additional laundry that has been forgotten is added. It is a position that can be done.

  The center of gravity of the aquarium 3 when predetermined water and clothes enter the aquarium 3 is indicated by C in FIG. The center of gravity C is located behind the legs 23 arranged on the front side of the washing machine body 1. When the center of gravity C is located in front of the washing machine main body 1 with respect to the front leg 23, if the user pushes the front door 21 downward with all the water tanks 3 pulled out, the entire washing machine main body 1 will fall down. There is a risk that.

In the present embodiment, as shown in FIG. 6, the center of gravity of the water tub 3 is set to the front leg 23 of the washing machine body 1 with the water tub 3 pulled out to a position where about half of the opening of the drum 2 and the water tub 3 is exposed. As a result, the water tank 3 can be prevented from being pulled forward, and the entire washing machine body 1 can be prevented from falling down by pushing the front door 21 downward.

  When the aquarium 3 is stored in the washing machine body 1 and the operation restart button is operated, the control device 24 drives the slide fixing solenoid to lock the slide movement of the slide structure 7 and drives the fixing device 25. Then, the fixing pin 26 is pulled out from the fixing hole 2d of the drum 2 so that the drum can rotate. Thereafter, the washing process is resumed according to a predetermined procedure in accordance with the situation when the operation is stopped.

  As described above, the washing machine of the present embodiment is a washing machine that draws out the drum together with the aquarium, and the center of gravity of the aquarium including other components drawn out together with the aquarium is the front and back of the constituent aquarium including other components. It arrange | positions so that it may arrange | position in the back | inner side rather than the center of a direction. Thereby, even if the water has entered the water tank, the water tank can be pulled out. In addition, since the center of gravity is located rearward even when the water tank is pulled out, the washing machine body can be prevented from falling forward, and the sliding distance of the water tank can be increased, so the opening of the drum Thus, it is possible to provide a washing machine with improved usability.

  In addition, by placing the center of gravity of the water tank including other parts drawn out together with the water tank between the front wheel and the rear wheel of the slide structure, the water tank can be moved smoothly, further improving usability. An improved washing machine can be provided. Furthermore, by regulating the withdrawal of the aquarium with a large amount of water in the aquarium within a certain range, the washing machine main body can be prevented from falling forward while the aquarium is pulled out, while the laundry being washed is It is possible to provide a washing machine that can be added and further improved in usability.

Thus, the water tank 3 can be drawn out so that the opening 3a of 2 is greatly exposed to the outside, so that it becomes easy to put laundry and a washing machine with improved usability can be provided.

  In the present embodiment, when the water tank 3 contains a predetermined amount or more of water, a slide brake device may be provided to slow the slide movement of the slide structure 7. With the slide brake device, the movement of the slide structure 7 can be slowed, and even when a large amount of water enters, the water in the water tank 3 jumps out vigorously when the water tank lid 6 is opened. There is no.

  In the above embodiment, the faucet A is not limited to a water tap installed in a building, and may be a supply unit such as bath water.

  Further, the water tank lid 6 may slide in the front-rear direction of the washing machine body 1. If it is configured to slide in the front-rear direction, the water tank lid 6 can be opened and closed in synchronization with the movement of the water tank 3, so that the water tank lid 6 automatically opens when the water tank 3 is pulled out, and the water tank 3 is placed inside the washing machine body 1. It becomes possible to make it the structure which the water tank cover 6 closes automatically, when it pushes into.

  The drum lid 5 and the water tank lid 6 may have a double-spreading configuration instead of a sliding opening / closing configuration. In the slide opening / closing configuration, the handle portion for sliding remains at the end of the opening, and the opening area for taking in and out the laundry in the opening becomes small. It can be secured.

  In the above-described embodiment, the operation of pulling out and pushing in the water tank 3 is operated by a user's pulling force or the like, but it may be operated using a motor or the like. By pressing an open / close button provided on the washing machine body 1, the control device 24 can drive the slide motor to slide the slide structure 7. For example, if the place where the washing machine body 1 is installed is lowered in the forward direction, the water tank 3 may jump forward as soon as the slide fixing solenoid is released. When the motor is used for the operation of pulling out and pushing in the water tank 3 as described above, even if the place where the washing machine main body 1 is installed is inclined, the water tank 3 is not unintentionally pulled out or pushed in.

  Moreover, since it is important for the smoothness of the slide movement of the water tank 3 to arrange | position a rail horizontally, it is preferable that the leg 23 of the four corners of the washing machine main body 1 is an adjustable leg which can adjust height. . In addition, it is desirable that a level is mounted so that the leveling of the washing machine body 1 can be easily understood.

  The drum 2 may be configured such that a portion facing the opening 2a is heavy in the circumferential direction. With this configuration, when the rotation of the drum 2 is stopped, the opening 2a can be stopped upward, so that the magnet 27 and the magnetic force detection sensor 28 are not necessary, and the cost can be suppressed.

  In the present embodiment, the position of the opening 2a of the drum 2 is detected by using the magnet 27 and the magnetic force detection sensor 28, but another method is used as a method for detecting that the opening 2a is positioned above. May be adopted. For example, the opening 2a is positioned above, such as a structure in which a protrusion is formed on the outer peripheral portion of the drum 2 and the protrusion detects that the protrusion has contacted with the expandable protrusion provided on the inner surface side of the water tank 3. Any configuration may be adopted as long as the configuration can detect this.

At least a part of each of the front door 21, the front side wall surface of the water tank 3, and the front side wall surface of the drum 2 may be configured to be transparent. With this configuration, it is possible to check how clothes are washed from the outside.

  In the present embodiment, the drum 2 is configured to restrict the rotation by the fixing device 25 and the fixing pin 26. However, the rotation of the drum 2 is locked by the fixing device 25 and the fixing pin 26 by operating a predetermined button. It is good also as a structure which removes. According to this configuration, since the drum 2 can be rotated as necessary, the outer wall surface of the drum can be maintained, and therefore a sanitary washing machine can be provided.

  A mechanism that is slowly closed immediately before the slide structure 7 is pushed into and stored in the washing machine body 1 may be provided between the washing machine body 1 and the slide structure 7. With this configuration, even if the water tank 3 is closed vigorously, it automatically closes slowly immediately before it is completely closed, so that safety is improved when a hand is sandwiched between the front door 21 and the washing machine body 1. Can do.

  The aquarium 3 is fixed to the slide structure 7 via a spring 11 and a damper 12, and the spring 11 and the damper 12 are arranged above and below the center of gravity B of the aquarium 3 including other components drawn out together with the aquarium 3. However, depending on the state of the laundry in the drum 2, the front side of the drum 2 may be greatly shaken. In such a case, the shaking of the water tank 3 can be reduced by connecting the front door 21 and the front side wall surface of the water tank 3 with a spring.

  In a state in which the slide structure 7 is slidable, that is, in a state in which the slide fixing solenoid is released, it is preferable to provide a water tank fixing lock device that prevents the water tank 3 from moving relative to the slide structure 7. With this configuration, when the water tank 3 is slid, the water tank 3 is not shaken and can be slid smoothly.

  The slide structure 7 may have another structure. For example, the support structure of the front door 21 may not be configured to support the lower portion of the front door 21 with two shafts, but by adding two shafts on the upper side of the front door 21 and supporting it with four shafts. It can be made strong. Moreover, it is good also as a structure supported instead of the structure which supports a top | upper surface and a bottom face with four pillars, and supporting with the sheet metal bent in the U shape, and can be suitably changed as needed.

  In the present embodiment, the drum 2 is configured to restrict rotation at a position where the drum lid 5 faces upward by the fixing device 25 and the fixing pin 26, but water is present in the water tank 3. Alternatively, the rotation may be restricted at a position where the drum lid 5 faces upward, and the rotation may be restricted while the drum lid 5 is inclined in the circumferential direction when washing is completed. With this configuration, the laundry in the drum 2 can be easily taken out, and usability can be improved. The operability can be further improved by making the tilt direction of the drum lid 5 selectable.

  Further, when washing is completed, the drum 2 may be stopped with the drum lid 5 facing upward, and the drum 2 may be pivotable with the brake applied. You may comprise so that it may regulate. With this configuration, the laundry in the drum 2 can be easily taken out, and the laundry can be prevented from falling from the gap between the drum 2 and the water tub 3, and the usability can be improved.

  As described above, the washing machine according to the present invention can be used for washing and drying machines and the like because the washing tub can be pulled out and the laundry can be taken in and out and the convenience of use can be improved.
