  However, the configuration of the conventional washing machine 1 as shown in FIG. 7 has the following problems.

  Along with the increase in couples working together, family washing is increasing in weekends, and the washing machine 1 is required to increase the capacity of the washable objects 23 that can be washed at once. For this reason, it is necessary to increase the capacity of the washing / dehydrating tub 10. To increase the capacity of the washing / dehydrating tub 10, the inner diameter of the washing / dehydrating tub 10 is increased or the depth is increased. Or do both.

However, when the inner diameter of the washing and dewatering tub 10 is increased, the product size of the width and depth of the washing machine 1 is increased, which causes a problem that the washing machine 1 cannot be installed. When the depth of the washing / dehydrating tub 10 is increased, the bottom of the washing / dehydrating tub 10 is disposed at the lower part of the washing machine 1, so that the cover located in front of the bottom 28 of the washing / dehydrating tub 10 as shown in FIG. The problem is that the object to be cleaned 23 cannot be seen and forgotten, or the distance L1 of the bottom back 29 of the washing and dewatering tub 10 is far from the front upper part of the washing machine 1, making it difficult to take out the object 23 to be cleaned. Will occur.

  In order to solve the above problems, a patent has been filed in which the water tank 4 is inclined when the object 23 to be cleaned such as clothes is taken out or put in (see Patent Document 2).

  However, in this configuration, when the operation is finished, the power switch is automatically turned off, the water tank 4 is tilted, and then the lid 26 is closed. When the power is turned on during the next operation, the water tank 4 is tilted, and the lid lock of the lid 26 is released after the tilting is completed. It cannot be done, and it is very bad to use. Further, when the power is turned off while the water tank 4 is inclined, the inclination of the water tank 4 is mechanically locked, and the lid 26 can be freely opened and closed. It is possible to immediately open the lid 26 and put it in, but since the state does not become the above unless the user turns off the power to the water tank 4 in an inclined state, the user ends the inclined state every time. Therefore, it has a configuration that is not easy to use. In addition, there is a problem that the usage becomes different from the conventional washing machine 1 and there is a sense of incongruity or it takes time to get used to it.

  In view of the above problems, an object of the present invention is to make it easier to put in and out an object to be cleaned and improve usability.

  In order to solve the above-described conventional problems, the washing machine of the present invention includes a washing and dewatering tub having a pulsator that stirs an object to be cleaned at a substantially central bottom, and a water tub in which the washing and dewatering tub is rotatably installed. , A driving means for rotating the pulsator and the washing / dehydrating tub, a lid for opening and closing an inlet for taking in and out the object to be cleaned, a lid opening and closing detecting means for detecting opening and closing of the lid, and a lid opening and closing detecting means for opening the lid The water tank is inclined when detected, and the tank opening / closing detection means is provided with a water tank inclination means for erecting the water tank when detecting that the lid is closed or during operation.

  Thus, when the user opens the lid to put the object to be washed into the washing machine, the lid open / close detection means detects that the lid has been opened, and the water tank tilting means tilts the water tank at a predetermined angle. If you stand in place and look at the washing and dehydrating tank, you can see the bottom of the washing and dehydrating tank that you could not see before, that is, you can see without looking into the washing and dehydrating tank As a result, it becomes easy to load an object to be cleaned.

  Then, put the object to be washed, turn on the washing machine, press the start button, close the lid, the water tank tilting means erect the water tank and wash the object to be washed with the water tank upright. Sometimes you can get the same washing, rinsing and dehydrating performance.

  Further, after the operation is finished, when the user opens the lid to take out the object to be cleaned, the lid opening / closing detection means detects that the lid has been opened, and the water tank tilting means tilts the water tank and the washing / dehydrating tank at a predetermined angle. Therefore, the user can see all the insides of the washing and dewatering tub simply by standing at a predetermined position of the washing machine. Also, if you take out the item to be washed from the top of the washing / dehydrating tub, make sure that you can see the item to be washed before and at the bottom of the washing / dehydrating tub without looking into the washing / dehydrating tub. Can be prevented from forgetting to take out and forget to dry.

At the same time, the bottom of the washing / dehydrating tub moves upward and approaches the user, so the user moves the hand to the bottom of the washing / dehydrating tub so that the bottom of the washing / dehydrating tub moves upward. The object to be cleaned can be taken out without being put in.

  The washing machine of the present invention is used in the same manner as before, and when the user puts in and out the object to be cleaned, the washing and dehydrating tub is inclined, so the user looks into the washing and dehydrating tub. Since the inside of the washing and dewatering tub can be seen from a predetermined position even without it, it is possible to improve the loading and unloading of the object to be cleaned and provide a convenient washing machine.

  The first invention is a washing and dewatering tub having a pulsator that stirs an object to be cleaned at a substantially central bottom, a water tub in which the washing and dewatering tub is rotatably installed, and the pulsator and the washing and dewatering tub are rotated. A drive means, a lid that opens and closes an inlet for taking in and out the object to be cleaned, a lid open / close detection means that detects opening and closing of the lid, and when the lid open / close detection means detects the opening of the lid, the water tank is inclined to When the open / close detection means detects that the lid is closed, or when it is in operation, it is equipped with a water tank tilting means that makes the water tank stand upright.When the user opens the cover to put the washing object in the washing machine, the lid opens and closes. The detection means detects that the lid is opened, and the water tank tilting means tilts the water tank at a predetermined angle, so that when the user stands in a predetermined position and looks at the washing / dehydrating tank, the washing / demounting that has not been seen until now You can see the bottom of the aquarium, ie Since in the washing and dewatering tank can be seen even without look into facilitates introduction of the object to be cleaned.

  Then, put the object to be washed, turn on the washing machine, press the start button, close the lid, the water tank tilting means erect the water tank and wash the object to be washed with the water tank upright. Sometimes you can get the same washing, rinsing and dehydrating performance.

  Further, after the operation is finished, when the user opens the lid to take out the object to be cleaned, the lid opening / closing detection means detects that the lid has been opened, and the water tank tilting means tilts the water tank and the washing / dehydrating tank at a predetermined angle. Therefore, the user can see all the insides of the washing and dewatering tub simply by standing at a predetermined position of the washing machine. Also, if you take out the item to be washed from the top of the washing / dehydrating tub, make sure that you can see the item to be washed before and at the bottom of the washing / dehydrating tub without looking into the washing / dehydrating tub. Can be prevented from forgetting to take out and forget to dry.

At the same time, the bottom of the washing / dehydrating tub moves upward and approaches the user, so the user moves the hand to the bottom of the washing / dehydrating tub so that the bottom of the washing / dehydrating tub moves upward. The object to be cleaned can be taken out without being put in.

  Therefore, when the user puts in and out the object to be cleaned in the same manner as before, the washing / dehydrating tub is inclined, so that the user does not look into the washing / dehydrating tub. Since the inside of the washing and dewatering tub can be seen from the position, it is possible to improve the loading and unloading of objects to be cleaned, and to provide a convenient washing machine.

  In the second invention, the water tank tilting means does not operate particularly when the detection time of the lid opening / closing detection means of the first invention is within a predetermined time, and even if the lid is opened and closed continuously, the water tank tilting means Since the tank is tilted or stopped in an upright state, the tank does not always operate in conjunction with quick opening and closing of the lid, and it does not become troublesome. Can be reduced.

  In particular, the third invention is provided with a water level detection means for detecting the water level of the water tank of the first or second invention, and when the water tank inclination means detects the water level more than a predetermined level while the water tank inclination means is inclining the water tank, The means erects the water tank and can prevent an overload from being applied to the water tank tilting means.

  At the same time, when the water tank tilting means is stored in the water tank with the water tank tilted, that is, when the water level in the water tank rises, the user feels anxiety that water will not leak from the bottom end of the water tank. Since the water is supplied with the water tank upright above a predetermined water level, the user's anxiety can be eliminated.

  In particular, the fourth aspect of the invention includes a suspension bar that hangs the water tank of the first to third aspects of the invention and is connected to a substantially upper portion of the housing, and the water tank inclination means moves at least the suspension bar substantially up and down. The water tank is inclined or upright with the water tank support portion of the suspension rod opposite to the suspension rod moved substantially up and down as a fulcrum.

  Therefore, the water tank can be tilted without newly providing a fulcrum for tilting the water tank, and the suspension rod moves substantially up and down while receiving substantially the same force as when standing upright. It is possible to prevent the durability from being deteriorated due to an uneven load or the like due to the inclination.

  At the same time, when the water tank is operated upright, the parts related to vibration during operation such as the water tank and the suspension rod will be in the same operation state as before if they are not subjected to the force from the water tank tilting means. Although it can be operated without causing any new problems, the height of the water tank changes depending on whether the water is present or not due to the expansion and contraction of the spring of the suspension rod due to the weight difference due to the presence or absence of water. On the other hand, the position of the housing support that comes into contact with the housing reinforcement of the suspension rod is the same height regardless of the presence or absence of water in the aquarium. The amount of change in the height direction can be omitted. Therefore, the water tank tilting means can tilt or stand the water tank more interlocked with the opening and closing of the lid, that is, it can tilt or stand the water tank with good response to the opening and closing of the lid. It is possible to make a washing machine that is easier to use.

  Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. In addition, the same structure as a prior art example attaches | subjects the same code | symbol, and abbreviate | omits description.

The suspension rod 2 and the water tank support 6 are fitted together and operate together.

  Since the lower portions 4a of the four water tanks 4 are suspended by the four suspension rods 2, the water tank 4 can swing freely.

  In addition, a water tank tilting means 32 for moving the suspension rod 2 arranged at the rear of the housing 3 up and down is provided. The water tank tilting means 32 is a wire 35 (belt) connected to the upper end portion 2a of the suspension rod 2. However, it is configured by an electric means 33 such as a motor that pulls or loosens the wire 35 via a pulley 34 that improves the slidability of the wire 35. And if the electric means 33 pulls the wire 35, the suspension rod 2 will be pulled up substantially upward, so that the rear lower part of the water tank 4 is lifted and the water tank 4 is inclined forward as shown in FIG. On the other hand, when the electric means 33 loosens the wire 35, the suspension rod 2 descends substantially downward and comes into spherical contact with the casing reinforcement 5, so that the water tank 4 stands upright as shown in FIG.

  A washing / dehydrating tub 10 is provided inside the water tub 4 so as to be spin-dryable. The washing and dewatering tub 10 has a pulsator 11 rotatably disposed at the bottom, and a lower blade 12 is provided integrally with the pulsator 11. The driving means 13 drives the pulsator 11 or the washing / dehydrating tub 10 via the speed reduction mechanism 14 and the rotating shaft 15.

  The lint water channel 16 is provided so as to extend from the pump chamber 17 on the outer periphery of the lower blade 12 of the pulsator 11 to the upper part or middle part of the washing and dewatering tub 10, and a removable lint filter 18 is provided on the upper part or middle part. ing.

  The drainage means 19 is constituted by a drain valve 20 and a drain hose 21, and drains washing water and rinsing water in the water tank 4. In addition, the drain hose 21 is connected to the housing 3, but is formed of a bellows or a telescopic hose to cope with the swinging of the water tank 4 during dehydration. Even if it inclines, the drainage hose 21 can be deformed without being bent, and it does not occur that a hole is opened by repeating the inclination or upright of the water tank 4.

  The water supply valve 22 supplies the washing water and the rinsing water into the water tank 4 according to the detection of the water level detection means 30 provided in the water tank 4.

  A drain hole 10a is provided on the side surface of the washing / dehydrating tub 10, and the washing / dehydrating tub 10 is driven by the drive means 13 in a state where the washing water or the rinsing water in the water tub 4 and the washing / dehydrating tub 10 has been drained. Is rotated, the object to be cleaned 23 receives a centrifugal force and moves to the side surface of the washing and dewatering tub 10, and the washing water and the rinsing water contained in the object to be cleaned 23 of the washing and dewatering tub 10 by the centrifugal force. It moves to the water tank 4 through the drain hole 10a provided in the side surface. The size of the drain hole 10a is such a size that the hook of the brassiere is not caught.

A fluid balancer 24 for reducing vibration during dehydration is provided in the upper part of the washing and dewatering tub 10.

  A lid 26 is provided on the upper frame 25 constituting the upper part of the washing machine 1 so as to be openable and closable. A control means 27 for controlling the electric means 33, the drain valve 20, the water supply valve 22, the drive means 13 and the like is provided behind the lid 26. Is provided. In FIG. 1 and FIG. 4, the control means 27 is disposed behind the lid 26, but there is no problem even in front of the lid 26 or on the left and right as long as the control means 27 can be accommodated.

  Lid opening / closing detection means 36 for detecting opening and closing of the lid 26 is disposed in the vicinity of the lid 26 with the lid 26 closed. Based on the information of the lid opening / closing detection means 36, that is, when detecting that the lid 26 is opened, the electric means 33 pulls the wire 35 to tilt the water tank 4 and detects that the lid 26 is closed. Loosens the wire 35 and brings the water tank 4 upright.

  When the lid 26 is opened, the insertion port 31 appears so that the object to be cleaned 23 can be taken in and out. When the lid 26 is closed, the insertion port 31 is obscured, so that the user may put a hand or the like during driving. It is safe because it is not.

  The operation in the above configuration will be described. When the lid 26 is closed and the washing machine 1 is left, the lid opening / closing detection means 36 detects that the lid 26 is closed. The suspension rod 2 is loosened until it sags, and the suspension rod 2 is accommodated in the housing reinforcement 5 so that the water tank 4 is kept upright. By doing so, the suspension rod 2 is supported by the casing reinforcement 5 even when the wire 35 is slackened, so that the upright state of the water tank 4 is equivalent to the conventional product and is attached to the water tank 4 and the water tank 4. Since the parts to be loaded only have the same load as the conventional one, there is no particular problem.

  When the user opens the lid 26, the lid opening / closing detection means 36 detects that the lid 26 has been opened, so that the electric means 33 pulls the wire 35 by a predetermined amount and the hanger 2 disposed on the rear side of the housing 3. Is pulled upward by a predetermined amount. By pulling up the suspension bar 2 disposed on the rear side of the housing 3 by a predetermined amount, the water tank 4 rotates forward with the water tank support portion 7 of the front suspension bar 2 as a fulcrum and tilts at a predetermined angle. As a result, as shown in FIGS. 4 and 5, when the user stands in a predetermined position and looks at the washing / dehydrating tub 10, the user can see the front side 28 of the washing / dehydrating tub 10 that has not been seen so far. That is, since it can be seen without looking into the washing / dehydrating tub 10, it is easy to load the article 23 to be cleaned.

  When an object to be cleaned 23 such as clothes is put into the washing and dehydrating tank 10 inclined at a predetermined angle via the water tank 4, the power of the washing machine 1 is turned on and a start button (not shown) is pushed, and the electric means 33 becomes a wire. 35 is loosened, the suspension rod 2 disposed on the rear side of the housing 3 is stored in a predetermined position of the housing reinforcement 5, and the water tank 4 is erected. When the water tank 4 stands upright, the pulsator 11 rotates forward and backward by the driving means 13 to detect the amount of the object to be cleaned 23. Then, since the amount of detergent required is displayed on the operation unit (not shown), the user puts a predetermined amount of detergent into a predetermined position (may be in the washing and dehydrating tank 10), and when the lid 26 is closed, the lid lock (Not shown) operates to prevent the lid 26 from opening. Thereafter, a predetermined amount of washing water is supplied from the water supply valve 22 into the washing and dewatering tub 10.

  The amount of the object to be cleaned 23 is detected after the water tank 4 is upright. However, when the amount of the object to be cleaned 23 is detected, only the object to be cleaned 23 is detected, so the amount of the object to be cleaned 23 is detected. Then, the water tank 4 may be made to stand upright.

  When a predetermined amount of wash water is supplied, the pulsator 11 rotates forward and backward to wash the article 23 to be washed.

When the washing process for a predetermined time is completed, the washing water in the water tub 4 is drained out of the washing machine 1 by the drain valve 20. When the washing water is drained, the washing and dewatering tub 10 is rotated at a predetermined rotational speed by the driving means 13 so that the washing water contained in the article to be washed 23 is separated from the article to be washed 23 and drained. One dehydration process is performed.

  When the first dehydration process is completed, a predetermined amount of rinsing water is again supplied from the water supply valve 22 to the water tank 4, and the pulsator 11 rotates forward and backward, and the first rinsing process is performed to rinse the object 23 to be cleaned. When the first rinsing process is completed, the rinsing water in the water tub 4 is drained out of the washing machine 1, and the washing and dewatering tub 10 is rotated at a predetermined rotational speed by the driving means 13, so that the object to be cleaned 23 is contained. A second dehydration step is performed in which the rinse water is separated from the object 23 and drained. Further, the rinsing water is supplied and a final rinsing process is performed. Thereafter, the rinsing water in the water tub 4 is drained, and a final dehydration process is performed in which the washing and dewatering tub 10 rotates at a predetermined rotational speed.

  When the final dehydration process is performed, the operation of washing the article to be cleaned 23 is completed.

  As described above, during the operation related to washing the article to be cleaned 23, the electric means 33 is loosened to the state where the wire 35 is slack, so that the lifting rod 2 does not have a force to be pulled up by the wire 35. Therefore, the operation of the washing machine 1 is equivalent to the conventional one.

  Further, during the operation related to washing the article 23 to be cleaned, the water tank 4 is in an upright state, and the lid 26 is not opened by the lid lock. During this operation, when the user presses a pause button (not shown) to stop the operation of the washing machine 1, the lid lock releases the lid 26, so that the user can open the lid 26. In this case, since it is in operation, the electric means 33 does not tilt the water tank 4 via the suspension rod 2 by pulling the wire 35. Alternatively, when the water level in the water tank 4 detected by the water level detection means 30 is less than or equal to a predetermined amount, the electric means 33 pulls the wire 35 to incline the water tank 4 via the suspension rod 2, and The wire 35 may be loosened so that the water tank 4 is not inclined. This is because if the water tank 4 is tilted in a state where water of a predetermined water level or more exists in the water tank 4, the water leaks out of the water tank 4 from the position where the water tank 4 is lowered and the washing water level and the excessive water level change. This is to prevent the washing performance from being deteriorated and to reduce the load on the electric means 33 and prevent the durability of the electric means 33 from being lowered.

  When the operation ends, the lid lock releases the lid 26 and turns off the power. However, the lid opening / closing detection means 36 continues to detect the opening / closing of the lid 26.

  When the user opens the lid 26 in order to take out the object 23 to be cleaned, the lid opening / closing detection means 36 detects that the lid 26 has been opened, so that the electric means 33 pulls the wire 35 and hangs it. The water tank 4 and the washing / dehydrating tank 10 are inclined at a predetermined angle via the bar 2.

  Therefore, as shown in FIG. 4 and FIG. 5, the user can see all the inside of the washing and dewatering tub 10 only by standing at a predetermined position of the washing machine 1, so that the object to be cleaned 23 can be washed and washed. If taken out from the top of the dewatering tub 10 in order, the portion 28 near the bottom of the washing / dehydrating tub 10 can be seen without looking into the washing / dehydrating tub 10. The object to be cleaned 23 in the portion 28 can be seen with certainty, and it is possible to prevent forgetting to take out and forget to dry.

  At the same time, the bottom back 29 of the washing and dewatering tub 10 moves upward, that is, close to the user. The object to be cleaned 23 that could not be taken out without being moved is moved to the upper part of the bottom part 29 of the washing / dehydrating tub 10 without moving the hand into the bottom part of the washing / dehydrating tub 10. It can be taken out.

  When the user closes the lid 26 after taking out the article 23 to be cleaned, the lid opening / closing detection means 36 detects that the lid 26 has been closed, and the electric means 33 loosens the wire 35 and brings the water tank 4 upright.

  When the lid 26 is opened, the water tank tilting means 32 tilts the water tank 4, and when the lid 26 is closed, the water tank 4 stands upright, that is, the water tank 4 tilts or stands up in conjunction with opening and closing of the lid 26. If the opening and closing of the water tank 26 is fast, if the water tank 4 repeatedly tilts and stands up corresponding to the speed, it will be bothersome to the contrary, and at the same time it will lead to the failure of the water tank tilting means 32. If it is less than the time, the water tank tilting means 32 may stop tilting or erecting the water tank 4.

  While the lid 26 is opened and the water tub 4 and the washing / dehydrating tub 10 are inclined at a predetermined angle, the user uses a bucket, a commercially available bath water supply unit or the like to perform washing and washing without turning on the power of the washing machine 1. When the water level detection means 30 detects a water level above a predetermined level by supplying water into the dehydration tank 10, the water tank tilting means 32 brings the water tank 4 and the washing and dehydration tank 10 upright. .

  According to this embodiment configured as described above, when the lid opening / closing detection means 36 detects that the lid 26 is opened, the water tank tilting means 32 tilts the water tank 4 and the washing / dehydrating tank 10 to a predetermined angle, and the lid When the opening / closing detection means 36 detects that the lid 26 is closed or during operation, when the user opens the lid 26 by raising the water tank 4 and the washing / dehydrating tank 10, the lid opening / closing detection means 36 causes the lid 26 to move. By detecting the opening, the electric means 33 constituting the water tank tilting means 32 pulls the wire 35 by a predetermined amount and pulls up the suspension rod 2 disposed on the rear side of the housing 3 by a predetermined amount. Since the water tank 4 rotates forward and tilts at a predetermined angle with the water tank support 7 of the hanging rod 2 as a fulcrum, the user stands at a predetermined position and performs washing and washing as shown in FIGS. Have you ever seen the dehydration tank 10? Washing and can be seen bottom front 28 of the dewatering tank 10, i.e., the inside of the washing and dewatering tank 10 can be seen even without look into facilitates introduction of the object to be cleaned 23.

  When the object to be cleaned 23 is put into the washing / dehydrating tub 10 inclined at a predetermined angle through the water tank 4 and the washing machine 1 is turned on and the start button is pressed, the electric means 33 loosens the wire 35 and opens the housing. The suspension rod 2 disposed on the rear side of the body 3 is housed in a predetermined position of the housing reinforcement 5 so that the water tank 4 is upright, and the object to be cleaned 23 is washed with the water tank 4 standing upright. The same washing, rinsing and dewatering performance can be obtained.

  Further, after the operation, when the user opens the lid 26 to take out the object 23 to be cleaned, the lid opening / closing detection means 36 detects that the lid 26 has been opened, and the electric means 33 passes the wire 35 and the suspension rod 2 through. Since the water tub 4 and the washing / dehydrating tub 10 are inclined at a predetermined angle, the user simply stands at a predetermined position of the washing machine 1 as shown in FIGS. Can see all. When the object to be cleaned 23 is taken out from the upper part of the washing / dehydrating tub 10, the object to be cleaned 23 at the bottom part 28 and the bottom part 28 of the washing / dehydrating tub 10 is moved inside the washing / dehydration tank 10. You can see it without looking into it, and you can prevent you from forgetting to take it out and forget it to dry.

  At the same time, the bottom back 29 of the washing / dehydrating tub 10 moves upward and approaches the user, so that the user moves his / her hand to the washing / dehydrating tub as much as the bottom 29 of the washing / dehydrating tub 10 moves upward. The object to be cleaned 23 can be taken out without being inserted into the bottom portion 29 of the bottom 10.

Therefore, when the user inserts and removes the object 23 to be cleaned in the same manner as in the past, the inside of the washing and dewatering tub 23 can be viewed from a predetermined position while the washing and dewatering tub 10 is inclined. Therefore, the taking in and out of the article to be cleaned 23 can be improved, and a convenient washing machine can be provided.

  Then, when the lid opening / closing detection means 36 detects that the lid 26 is opened, the electric means 33 tilts the water tank 4, and when the lid opening / closing detection means 36 detects that the lid 26 is closed, the electric means 33 brings the water tank 4 upright. However, when the lid 26 is continuously opened and closed, the water tank 4 repeats tilting and uprighting, and the water tank 4 is always in operation. This may lead to failure of the means 32.

  Therefore, when the detection time for the lid opening / closing detection means 36 to detect that the lid 26 is opened or closed is within a predetermined time, the water tank tilting means 32 is not operated so that the lid 26 is continuously opened and closed. The water tank tilting means 32 is stopped in a state where the water tank 4 is tilted or upright, so that the water tank 4 does not always operate in conjunction with the quick opening and closing of the lid 26, which is troublesome. Moreover, the failure of the water tank tilting means 32 can be reduced.

  If the lid opening / closing detection means 36 detects the opening / closing of the lid 26 within a predetermined time, the water tank tilting means 32 can stop the water tank 4 in a tilted state, and the user can use it easily. It is good to maintain.

  Then, when the lid 26 is opened, the water tank tilting means 32 causes the water tank 4 to be tilted. In this state, the user does not turn on the power and the user is not connected to the bucket or the washing machine 1. Water may be supplied into the washing and dewatering tub 10 from water, a commercially available bath water supply unit, or the like. The water level detecting means 30 detects the water level of the water tub 4 while the water tank tilting means 32 is tilting the water tank 4. When the water level is detected above a predetermined level, the water tank tilting means 32 can prevent the water tank tilting means 32 from being overloaded by causing the water tank 4 to stand upright.

For example, the weight applied to the water tank tilting means 32 is equivalent to the weight applied to two of the four suspension rods 2, so after the dehydration process,
(Weight of water tank: 20 kg + clothing weight after dehydration: 20 kg) / 2 = 20 kg
That is, 60 L of water can be supplied to the aquarium 4 until it overflows, so when water is supplied to the aquarium 4 until it overflows,
20kg + 60kg / 2 = 50kg
This force can be prevented from being applied to the water tank tilting means 32.

  At the same time, when the water tank tilting means 32 is stored in the water tank 4 with the water tank 4 tilted, that is, when the water level in the water tank 4 rises, water does not leak from the inclined lower end side of the water tank 4, In order to give the user a sense of anxiety, water is supplied in a state where the water tank 4 is kept upright above a predetermined water level, so that the user's anxiety can be eliminated.

  Then, as shown in FIG. 1 and FIG. 4, the water tank 4 is moved substantially up and down by the water tank tilting means 32 substantially moving up and down the suspension rod 2 that is suspended from the water tank 4 and connected to the substantially upper part of the washing machine 1. The water tank support portion 7 of the suspension rod 2 opposite to the suspension rod 2 is tilted or erected with the fulcrum as a fulcrum.

  Therefore, the water tank 4 can be tilted without newly providing a fulcrum for tilting the water tank 4, and the suspension rod 2, the spring 8, the damper 9, etc. are in a state of receiving substantially the same force as when standing upright. Since it moves substantially up and down, it is possible to prevent the durability from being deteriorated due to an uneven load or the like due to the inclination of the water tank 4.

At the same time, when the water tank 4 is operated upright, the parts related to vibrations during operation such as the water tank 4 and the suspension rod 2 are equivalent to the conventional ones if they are not subjected to the force from the water tank tilting means 32. In the case where the water tank tilting means 32 pulls up the water tank 4 and tilts it directly as shown in FIG. When the water tank 4 is operated upright, the height direction of the water tank 4 varies depending on whether the water 8 is present or not due to the expansion and contraction of the spring 8 of the suspension rod 2 due to the weight difference depending on the presence or absence of water (for example, (the overflow in the water tank 4 When there is water up to: line A)-(when there is no water in the water tank 4: line B) = 30 mm), the water tank tilting means 32 is the amount of change in the height direction of the water tank 4 due to the presence or absence of water during operation. Taking into account the force from the tank tilting means 32 It is necessary to sag the wire 35 of the water tank tilting means 32 in addition to the amount of change in the height direction of the water tank 4 due to the presence or absence of water. The position of the housing support 6 that contacts the water tank is water regardless of the presence or absence of water in the water tank 4, that is, the water tank 4 is at the same height even if the water tank 4 is at the position of line A or line B in FIG. The wire 35 of the water tank tilting means 32 can be slackened without adding a change amount (A-B) in which the height direction changes depending on the case. That is, as shown in FIGS. 1 and 4, if the suspension rod 2 is configured to be pulled up, it is not necessary to take into account the amount of change (AB) in the height direction of the water tank 4 due to the presence or absence of water. The amount by which the water tank tilting means 32 pulls or sags the wire 35 can be reduced by that amount, and the water tank 4 can be tilted or erected more interlocked with the opening and closing of the lid 26. That is, the water tub 4 can be tilted or erected with good response to the opening and closing of the lid 26, and the washing machine 1 can be made more convenient.

  Since the lid opening / closing detection means 36 always detects the opening / closing of the lid 26 even after the operation related to the washing of the article 23 to be washed, if the lid 26 is opened after the operation relating to the washing is completed, Although the water tank 4 and the washing / dehydrating tank 10 are inclined to a predetermined angle by the means 33, the energization of the lid opening / closing detection means 36 and the electric means 33 is continued from this time until the power supply for the next washing is turned on. As a result, the lid opening / closing detection means 36 may not always need to detect the opening / closing of the lid 26. Even if the lid 26 is opened or closed until the power for the next washing is turned on, the electric means 33 does not operate the wire 35, so that the water tank 4 and the washing / dehydrating tank 10 are always inclined at a predetermined angle. As shown in FIG. 5, the user can always see all the inside of the washing and dewatering tub 10 when standing in a predetermined position. That is, when the user mainly puts and removes the article 23 to be cleaned, the water tub 4 and the washing / dehydrating tub 10 are in an inclined state, and the convenience is improved.

  Further, an inclination lock mechanism (not shown) may be provided, and the inclination may be locked by the inclination lock mechanism when the water tub 4 and the washing / dehydrating tub are always inclined as described above.

  As described above, the washing machine according to the present invention can make it easy to take out an object to be cleaned, and thus can be applied not only to a home-use washing machine but also to a business-use washing machine.
