Description

The present invention relates to a washing machine for taking in and out an object to be cleaned from an upper surface of a housing.

  Conventionally, this type of washing machine is configured as shown in FIG. 11 (see, for example, Patent Document 1). FIG. 11 is a side sectional view of a conventional washing machine. In FIG. 11, the washing machine includes a casing 101 configured in a substantially rectangular parallelepiped, and a water tank 102 configured in a substantially cylindrical shape is suspended inside the casing 101 by a suspension rod 103. The water tank 102 includes a washing / dehydrating tank 104 having a substantially cylindrical shape therein so as to be rotatable. The washing and dewatering tub 104 has a stirring blade 105 for freely stirring an object to be cleaned 115 such as clothes and washing water at the bottom thereof. The housing 101 has a lid 106 that opens and closes an opening through which an object 115 is taken in and out. In addition, the front portion of the lid 106 is provided with a control device 107 that executes a series of steps such as washing, rinsing, and dehydration, and an operation unit 108 that sets an operation course and the like.

  FIG. 12 is a plan view of a reinforcing support portion provided at the upper corners of the casing. The reinforcing support portions 109 are provided at the upper corners 101 a of the housing 101, support the suspension rod 103, and also serve as reinforcement of the housing 101. The four suspension rods 103 are disposed on the four corner upper portions 101 a of the housing 101 via reinforcement support portions 109. The four suspension rods 103 are provided with a damping member 110 at the lower end, and suspend the water tank 102 through four damper support portions 102 a formed at the lower part of the water tank 102. FIG. 13 is a cross-sectional view of a hanging rod provided with a damping member. The damping member 110 includes a damper 112 and a spring 113 inside a damper case 111 having a spherical upper surface, and suppresses the vibration of the water tank 102 that is generated during operation of the washing machine from being transmitted to the casing 101. As shown in FIGS. 12 and 13, the suspension rod 103 is disposed at the upper end via a spherical support portion 114 that makes spherical contact with the spherical portion 109 a of the reinforcing support portion 109. Moreover, FIG. 14 is sectional drawing of the damper support part vicinity formed in the water tank. As shown in FIGS. 13 and 14, the damper support portion 102 a and the vibration damping member 110 are configured to make spherical contact. Due to the upper and lower spherical contact configurations, excessive force is not applied to the suspension rod 103 and the housing 101 even when the water tank 102 is swung by vibration.

  However, the configuration of the conventional washing machine as shown in FIG. 11 has the following problems. That is, since the water tank 102 is only suspended by the four suspension rods 103 so as to be able to swing freely in the washing machine, the water tank 102 is located at the center of the four suspension rods 103 when stopped. In addition, the suspension rod 103 is configured such that the upper reinforcing support portion 109 side widens in order to improve the vibration damping effect. Therefore, the distance from the front surface part of the water tank 102 to the front surface part of the housing | casing 101 becomes large, and exists in the position away from the front surface of the washing machine. That is, as shown in FIG. 15, for example, when a woman about 150 cm to 155 cm tall stands in front of the washing machine and looks inside the washing / dehydrating tub 104, the bottom of the washing / dehydrating tub 104 is in front. There is a possibility that a certain object to be cleaned 115a cannot be seen and forgotten. In order to prevent forgetting, you need to look closely. Further, since the distance from the user to the bottom of the washing / dehydrating tub 104 is far from the user, it is necessary to greatly extend the hand and it is difficult to take out the article to be cleaned 115b.

  In addition, there is an increase in collective washing, and there is a need for a larger capacity of the washing / dehydrating tub 104. In order to accommodate a larger capacity without increasing the installation area of the washing machine, It is necessary to increase the depth of the water tank 104. Then, the object to be cleaned 115a in front of the bottom of the washing / dehydrating tank 104 becomes more difficult to see, or the distance from the user to the bottom of the washing / dehydrating tank 104 is further away from the user, making it difficult to take out the object to be cleaned 115b. It becomes.

  In order to solve such a problem, a technique is disclosed in which the water tank 102 is inclined when the object to be cleaned 115 such as clothes is taken out or put in (see, for example, Patent Document 2).

  FIG. 16 is a schematic side sectional view of the washing machine described in Patent Document 2, and shows a state where the water tank is inclined. The washing machine described in Patent Document 2 includes a case 201, a water tank 202 disposed in the case 201, a suspension rod 203 that supports the water tank 202, and a tilt that tilts the water tank 202 with a tilting fulcrum 220 a as a fulcrum. And a control unit, and the inclination angle of the water tank 202 can be changed according to the process from when the clothes are put in to when the washed and dehydrated clothes are taken out. The tilting part has a configuration in which a tilting motor 221 having a pinion 222 fixed to a rotation shaft is attached to a horizontal base 219, and a rack 223 is disposed on the tilting base 220 so as to be movable up and down so that the pinion 222 and the rack 223 are engaged with each other. . Accordingly, when the rack 223 pushes up the tilting table 220 by the rotation of the tilting motor 221, the tilting table 220 tilts with the tilting fulcrum 220a as the center of tilting. This washing machine includes, for example, a mechanism in which clothes are washed with the water tank 202 tilted, dewatered with the water tank 202 standing upright, and clothes are taken out with the water tank 202 tilted.

  However, in the configuration described in Patent Document 2, because of the configuration in which the gear is combined with the tilting motor, there is a problem that the washing machine becomes large and the installation property is lowered or the amount of energy used for tilting is increased. Have

  The present invention solves the above-mentioned conventional problems, and provides a washing machine that improves ease of use by facilitating the removal and installation of objects to be cleaned without lowering the installation property or increasing the amount of energy used. For the purpose.

  In order to solve the above-described conventional problems, a washing machine according to the present invention includes a housing having an input port through which an object to be cleaned is put in and out, and a washing / dehydrating tub having an opening at the top to accommodate the object to be cleaned. A water tub in which the washing and dewatering tub is rotatably set, a suspension rod that supports the water tub, a lid that opens and closes the inlet, and the water tub is moved forward when the lid is opened, And a water tank moving part that moves the water tank to its original position when the lid is closed.

  As a result, when the user opens the lid, the water tank moves in the forward direction of the washing machine by the water tank moving part, and the position where the water tank is supported by the hanging bar is the front hanging bar on the front lower side, the rear hanging Since the rod moves to the front upper side, the water tank and the washing and dewatering tank inside thereof are inclined to the front side. Therefore, the user can easily see the object to be cleaned in front of the bottom of the washing / dehydrating tank without looking into the washing / dehydrating tank and never forget to take it out. In addition, the user can easily reach his / her hand as long as the bottom of the washing / dehydrating tub moves in front of the washing machine, and can easily take out the object to be cleaned. Therefore, when the user stands in a predetermined position and looks at the washing / dehydrating tub, it becomes easier to see the front of the bottom of the washing / dehydrating tub, which has been difficult to see, and it is easy to reach and the objects to be cleaned can be taken in and out. To improve usability.

  In the washing machine of the present invention, when the user stands in a predetermined position and looks at the washing / dehydrating tub, the front of the bottom of the washing / dehydrating tub, which has been difficult to see so far, is easily visible and easily reachable.

  A washing machine according to a first aspect of the present invention is a housing having a loading port through which an object to be cleaned is taken in and out, a washing and dewatering tub having an opening at the upper side for accommodating the object to be cleaned, and the washing and dehydrating tub A water tank rotatably installed therein, a suspension rod that supports the water tank, a lid that opens and closes the charging port, and when the lid is opened, the water tank is moved forward, and when the lid is closed, And a water tank moving part that moves the water tank to the original position.

  As a result, when the user opens the lid, the water tank moves in the forward direction of the washing machine by the water tank moving part, and the position where the water tank is supported by the hanging bar is the front hanging bar on the front lower side, the rear hanging Since the rod moves to the front upper side, the water tank and the washing and dewatering tank inside thereof are inclined to the front side. Therefore, the user can easily see the object to be cleaned in front of the bottom of the washing / dehydrating tank without looking into the washing / dehydrating tank and never forget to take it out. In addition, the user can easily reach his / her hand as long as the bottom of the washing / dehydrating tub moves in front of the washing machine, and can easily take out the object to be cleaned. Therefore, when a user stands in a predetermined position and looks at the washing / dehydrating tub, it becomes easier to see the front of the bottom of the washing / dehydrating tub, which has been difficult to see, and it is easy to reach the back of the bottom. Becomes easier and improves usability.

  In a second aspect of the invention, in particular, in the first aspect of the invention, the water tank moving part has a contact part that comes into contact with the water tank, and a connecting part that transmits the movement of the lid to the contact part, A force is applied to the upper part of the water tank to incline the water tank. Thereby, since the aquarium moving part does not use a motor or the like for driving, the installation property does not deteriorate and the amount of energy used does not increase.

In a third aspect of the invention, in particular, in the first or second aspect of the invention, the water tank moving part includes a movement release part that releases the movement of the water tank when a predetermined force is applied to the contact part. It is a thing. When a predetermined amount or more of water is present in the water tank, the water tank moving unit cannot push the water tank by the movement canceling unit. Therefore, when the amount of water in the aquarium is less than or equal to the predetermined amount, the aquarium moving unit moves the aquarium forward, and when it is greater than or equal to the predetermined amount, the aquarium moving unit does not move the aquarium forward by the movement release unit. To. Thereby, it can prevent that an overload is added to a water tank moving part, and it can prevent and can provide a highly reliable washing machine.

  In a fourth aspect of the invention, in particular, in any one of the first to third aspects of the invention, the water tank moving part comprises the connecting part made of a wire and the contact part made of a lever. Thereby, since the aquarium moving part does not use a motor or the like for driving, the installation property does not deteriorate and the amount of energy used does not increase.

  According to a fifth aspect of the invention, in particular, in any one of the first to fourth aspects of the invention, the suspension rod suppresses vibration of the water tank, and when the amount of water and objects to be cleaned in the water tank increases, A damping member that lowers a holding position, and the abutting portion is located at an upper portion of the water tank, and in the height direction, the weight of the water tank is less than a predetermined weight due to the action of the vibration damping member; It is configured to push a position that does not exist in a substantially horizontal direction. When there is nothing in the washing / dehydrating tub and the water tub, the force applied to the suspension bar is the smallest, so the water tub is held at the uppermost holding position. And if water is supplied to a water tank and the weight of a water tank increases, the holding position of a water tank will fall. That is, the water tank moves up and down depending on the state in the water tank. Therefore, when the water tank is light, the water tank exists at a position where the abutting portion of the water tank moving unit pushes the water tank, so that the water tank can be moved in front of the washing machine. On the other hand, when the water tank is heavy, since the water tank does not exist at the position where the abutting portion pushes the water tank, the water tank does not move and remains at the original position between the four hanging rods. Therefore, with the above configuration, the abutment portion can be pushed only when the water tank is below a predetermined weight, so that it is possible to simplify the structure without adding parts such as a movement release unit, and to improve the reliability of the water tank moving unit. Can be increased.

  In a sixth aspect of the invention, in particular, in any one of the first to third aspects of the invention, the water tank moving part is configured by configuring the connecting part and the contact part with one wire. Thereby, it can suppress that the part which pushes a water tank with a wire becomes linear or strip | belt shape, and a load concentrates, and can incline a water tank reliably.

  In a seventh aspect of the invention, in particular, in any one of the first to sixth aspects of the invention, an operation unit for setting a washing operation is provided behind the lid. Thereby, since there are no parts in the front upper part of the washing machine, the charging port can be formed up to the front upper part. Accordingly, the width between the front portion of the upper frame and the inlet can be reduced, and the height of the front portion of the upper frame can be reduced, so that the object to be cleaned can be taken in and out more easily and the usability can be further improved. be able to.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a side sectional view of a washing machine according to Embodiment 1 of the present invention. In FIG. 1, the washing machine 1 includes a housing 3 that forms an outer shell, and includes a water tank 4 supported by four suspension rods 2 inside the housing 3. The housing 3 has an insertion port 6 for taking in and out an object to be cleaned 5 such as clothes on the upper surface, and a lid 7 for opening and closing the insertion port 6 is provided.

Inside the water tub 4, a washing and dewatering tub 10 having an opening on the upper side and storing the object to be cleaned 5 is rotatably provided. 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 drive unit 13 such as a motor drives the pulsator 11 or the washing and dewatering tub 10 via the speed reduction mechanism 14 and the respective rotation shafts 15. The lint channel 16 is a pump chamber 1 on the outer periphery of the lower blade 12 of the pulsator 11.
7 is provided so as to reach the upper part of the washing and dewatering tub 10, and a lint filter 18 that can be attached to and detached from the upper part is provided to collect lint such as lint and dust contained in washing water and rinsing water.

  The drainage part 19 is comprised from the drainage valve 20 and the drainage hose 21, and drains the washing water in the water tank 4, and a rinse water. Although the drainage hose 21 is held by the housing 3, the drainage hose 21 is formed of a bellows or an expansion / contraction hose in order to cope with a state in which the water tank 4 sways during dehydration. Therefore, as shown in FIG. 4, even if the water tub 4 moves in the front direction of the washing machine 1, the drainage hose 21 can be deformed without being bent, and by repeating the movement of the water tub 4 in the front-rear direction. There is no such thing as opening a hole. The water supply valve 22 provided in the upper part supplies tap water serving as washing water or rinsing water into the water tank 4.

  A drain hole 10 a is provided on the entire circumference of the side surface of the washing / dehydrating tub 10. The driving unit 13 dehydrates the object to be cleaned 5 by rotating the washing / dehydrating tub 10 at a high speed 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. When the washing and dewatering tub 10 rotates at a high speed, the object to be cleaned 5 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 5 are caused by the centrifugal force. It moves to the water tank 4 through the drain hole 10a. A fluid balancer 24 for reducing vibration during dehydration is provided in the upper part of the washing and dewatering tub 10.

  A lid 7 is provided on the upper frame 25 constituting the upper part of the housing 3 so as to be freely opened and closed. Behind the lid 7 is provided an operation unit 27 having a setting unit for setting a washing operation and a display unit for displaying a driving state. In FIG. 1, the operation unit 27 is arranged behind the lid 7, but there is no problem even in front of the lid 7 and the upper frame body 25 as long as it does not affect the usability of the operation unit 27. When the lid 7 is opened, the insertion port 6 appears so that the object to be cleaned 5 can be taken in and out, and when the lid 7 is closed, the insertion port 6 is covered.

  The support of the water tank 4 will be described. FIG. 2A is a cross-sectional view of the reinforcing support portion and the suspension rod support portion of the washing machine in the present embodiment. FIG. 2B is a plan view of the reinforcing support portion. FIG. 3 is a cross-sectional view of the vicinity of a damper support portion formed in the water tank. The reinforcement support portions 28 are provided at the upper corners 3 a of the housing 3, support the suspension rod 2, and also serve as reinforcement of the housing 3. The four suspension rods 2 that support the water tank 4 are arranged via the reinforcement support portions 28 of the four corner upper portions 3a of the housing 3, and the upper reinforcement support portion 28 side is widened to improve the vibration damping effect. It is configured. The four suspension rods 2 are provided with a suspension rod support portion 29 at the upper end, a damping member 8 at the lower end, and the water tank 4 via the four damper support portions 4 a formed at the lower portion of the water tank 4. Suspended and supported.

  The reinforcing support portion 28 and the suspension rod support portion 29 are in spherical contact. The damping member 8 includes a spring 30 and a damper 31 inside a damper case whose upper surface is spherical, and suppresses the vibration of the water tub 4 generated during operation of the washing machine 1 from being transmitted to the housing 3. The damping member 8 and the damper support portion 4a are also in spherical contact. Since the water tank 4 is suspended in the center by the four suspension rods 2, it can swing freely. Moreover, even if the water tank 4 shakes around by vibration by these upper and lower spherical contact configurations, an unreasonable force is not applied to the hanging rod 2 and the housing 3.

Next, the water tank moving part of the washing machine of the present invention will be described with reference to FIGS. 1 and 4. FIG. 4 is a side cross-sectional view of a state in which the water tank of the washing machine has moved according to the present embodiment. A water tank moving unit 32 that moves the water tank 4 back and forth is provided behind the washing machine 1. The water tank moving unit 32 includes a contact part 35 that contacts the water tank 4 and moves the water tank 4, and a connecting part 33 that transmits the movement of the lid 7 and drives the contact part 35. Since there is no motor or the like that needs a power source to drive each part, the housing 3 does not become large and the installation property does not decrease, and the amount of energy used does not increase. The movement of the lid 7 may be moved or rotated depending on the portion of the lid 7, but the connecting portion 33.
May use any movement. The configuration may be a transmission configuration using a link mechanism or a gear, or may be a transmission configuration using a wire or a belt, and is not particularly limited. Moreover, the structure which pushes the water tank 4 from back may be sufficient as the contact part 35 like this Embodiment, and the structure which pulls the water tank 4 from the front may be sufficient. Further, in the configuration in which the water tank 4 is pushed from the rear, in addition to being pushed by the lever 35a, the rear of the water tank 4 may be held by a wire as will be described later. In any case, there is no particular limitation as long as the water tank 4 can be tilted without using power such as a motor.

  In the present embodiment, the connecting portion 33 includes an arm portion 36 formed integrally with the lid 7, a wire 33 a, and a pulley 34, and the contact portion 35 includes a lever 35 a. Thereby, the rotational movement of the lid 7 is the movement of the arm portion 36 formed integrally with the lid 7. The movement of the arm portion 36 is transmitted to the lever 35a via the wire 33a connected to the arm portion 36 and the pulley 34 that improves the slidability of the wire 33a. That is, by pulling or loosening the wire 33a with the arm portion 36, the lever 35a is driven, and the upper part of the water tank 4 is pushed and moved in the front-rear direction.

  Specifically, as shown in FIGS. 1 and 4, when the lid 7 is opened, an arm portion 36 formed by extending the lid 7 rotates in a direction of pulling the wire 33 a. Then, the lever 35a is lifted and pushes the water tank 4 from the rear. As a result, the water tank 4 moves in the forward direction of the washing machine 1. On the other hand, when the lid 7 is closed, the arm portion 36 rotates in the direction of loosening the wire 33a, so that the lever 35a returns to the original position and pushes the water tank 4, and the water tank 4 has four suspension rods 2. Move to the original position between.

  FIG. 5 is a schematic diagram showing movement of the water tank of the washing machine in the present embodiment. As shown in FIG. 5, in the water tank 4, the damper support portion 4 a is supported by the four suspension rods 2, and the suspension rod 2 performs a circular motion back and forth around the reinforcement support portion 28. Since the suspension rod 2 does not expand and contract, if the water tank 4 is moved forward so that the suspension rod 2 moves circularly by an angle θ by applying a pressing force F, the front damper support portion 4a is moved rearward and rearward. The damper support portion 4b moves forward and upward, and the water tank 4 is inclined forward. Although depending on the weight of the water tank 4 and the amount of movement, the movement of the load accompanying the movement of the water tank 4 causes the front vibration damping member 8 to contract and the rear vibration damping member 8 to extend. Thereby, it is promoted that the water tank 4 inclines to the front side.

  Therefore, as shown in FIG. 4, when the water tank moving unit 32 moves the water tank 4 in the forward direction of the washing machine 1, the washing / dehydrating tank 10 and the water tank 4 are inclined forward. The inclination angle of the water tank 4 varies depending on the distance from the front surface portion of the water tank 4 to the front surface portion of the housing 3. The longer the distance, the larger the inclination angle can be achieved by the configuration of the four suspension rods 2. It is. However, at that time, since the size of the washing machine 1 in the front-rear direction is also increased, it is necessary to consider the influence on the installation property.

  In addition, it is desirable that the insertion port 6 is formed in an optimum shape in which the user can most easily put in and out the cleaning object 5 at a position where the water tank 4 is moved forward by the lever 35a when the lid 7 is opened. . That is, the shape of the inlet 6 is formed so as to coincide with the upper opening of the washing / dehydrating tub 10 as much as possible at the position where the water tub 4 has moved forward so that the upper opening of the washing / dehydrating tub 10 is not hidden. It is desirable that

Further, the lever 35a when the lid 7 is closed needs to be arranged at a position where it does not hit even when the water tub 4 swings during the operation of the washing machine 1. As a result, the lever 35a collides with the aquarium 4 to generate noise, the lever 35a or the aquarium 4 is broken, or the vibration trajectory of the aquarium 4 changes to change the vibration performance. Can be prevented. Therefore, it is possible to prevent the lever 35a from adversely affecting the operation of the washing machine 1, and it is possible to obtain a washing performance equivalent to the conventional one.

  Based on the above configuration, the operation of the washing machine 1 of the present embodiment will be described. When the lid 7 is closed and the washing machine 1 is left, the arm portion 36 of the lid 7 loosens the wire 33a and the lever 35a does not push the water tank 4, so the water tank 4 is located between the four suspension rods 2. Located in the middle. As a result, the water tank 4 is in a state equivalent to a conventional washing machine, and the water tank 4 and parts attached to the water tank 4 are only subjected to a load equivalent to that of the conventional one.

  When the user opens the lid 7, the arm portion 36 of the lid 7 pulls the wire 33 a and the lever 35 a pushes the water tank 4. As a result, the water tank 4 moves in the forward direction of the washing machine 1 and tilts forward due to the effect of the four hanging rods 2. As a result, when the user stands in a predetermined position and looks at the washing / dehydrating tub 10, it becomes easy to see the front of the bottom of the washing / dehydrating tub 10 that has been difficult to see. That is, since it can be seen without looking into the washing / dehydrating tub 10 largely, it is easy to put the article 5 to be cleaned.

  Next, the user puts an object to be cleaned 5 such as clothes into the washing / dehydrating tub 10 moved in the forward direction of the washing machine 1 together with the water tub 4, turns on the washing machine 1, and starts the operation unit 27. When is pressed, the pulsator 11 is rotated in both forward and reverse directions by the drive unit 13 to detect the amount of the object to be cleaned 5. Since the washing machine 1 displays the necessary amount of detergent on the operation unit 27, the user closes the lid 7 by putting a predetermined amount of detergent into a predetermined position. Then, a lid lock (not shown) operates to prevent the lid 7 from being opened. At the same time, the arm portion 36 of the lid 7 loosens the wire 33a and the lever 35a does not press the water tank 4, so that the water tank 4 and the washing / dehydrating tank 10 return to their original positions between the four suspension rods 2.

  Thereafter, a predetermined amount of washing water is supplied from the water supply valve 22 into the washing and dewatering tub 10. When a predetermined amount of washing water is supplied, a washing step is performed in which the pulsator 11 rotates to wash the article 5 to be washed. When the washing step 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 drive unit 13, and the washing water contained in the article to be washed 5 is separated from the article to be washed 5 and drained. The dehydration step is performed.

  When the first dehydrating step is completed, a predetermined amount of rinsing water is supplied from the water supply valve 22 to the water tank 4, the pulsator 11 is rotated, and the first rinsing step is performed to rinse the object 5 to be cleaned. When the first rinsing step is completed, the rinsing water in the water tub 4 is drained out of the washing machine 1 by the drain valve 20, and the washing and dewatering tub 10 is rotated at a predetermined rotational speed by the drive unit 13, so that the second A dehydration step is performed. When the second dehydration step is completed, a predetermined amount of rinsing water is supplied again from the water supply valve 22, and the final rinsing step is performed. When the final rinsing step is completed, the rinsing water in the water tub 4 is drained by the drain valve 20, the washing and dewatering tub 10 is rotated at a predetermined rotational speed, and the final dewatering step is performed. When the final dehydration step is completed, the operation for washing the article to be cleaned 5 is completed.

  When this series of steps is executed, the water tank 4 moves to the original position between the four suspension rods 2. Since the object to be cleaned 5 is washed in that state, the same washing, rinsing and dehydrating performance as in the conventional case can be obtained during operation.

Then, after the operation is finished, when the user opens the lid 7 to take out the object 5 to be cleaned, the arm portion 36 of the lid 7 pulls the wire 33 a and the lever 35 a pushes the water tank 4. As a result, the water tank 4 moves in the forward direction of the washing machine 1 and tilts forward due to the effect of the four hanging rods 2. As a result, the user can easily see all of the inside of the washing and dewatering tub 10 only by standing at a predetermined position of the washing machine 1. As a result, when the objects to be cleaned 5 are sequentially taken out from the upper part of the washing / dehydrating tub 10, the washing / dehydrating tub is not required to look into the washing / dehydrating tub 10 in the same manner as when the objects to be cleaned 5 are loaded. The object 5 to be cleaned in front of the bottom part 10 can be easily seen, so that the user forgets to take out the object 5 and forget to dry it.

  At the same time, the bottom of the washing / dehydrating tub 10 also moves in the forward direction of the washing machine 1 and rises with the inclination of the washing / dehydrating tub 10. In other words, since the user is approaching the user, the user has to extend his / her hand like the conventional one to be cleaned, which cannot be taken out unless the hand is bent greatly and the hand is extended to the bottom of the washing / dehydrating tub 10. Can also remove the article 5 to be cleaned.

  When the user closes the lid 7 after taking out the object 5 to be cleaned, the arm portion 36 of the lid 7 loosens the wire 33a and releases the lever 35a from pushing the water tank 4. The dewatering tank 10 moves to the original position between the four suspension rods 2.

  In addition, there is a washing machine capable of storing water of, for example, 60 liters or more in the water tank 4. In such a washing machine, when the lid 7 is opened during the washing step or the rinsing step and the lid 7 is opened, the pressing force required for the lever 35a to push the water tank 4 becomes very large. There is a possibility that the lever 35a cannot push the water tank 4 due to breakage or the wire 33a being cut. In order to cope with such a situation, it is desirable to provide the movement release unit 37 in the lever 35a. This prevents the lever 35a from forcibly pushing the water tank 4 when the necessary pressing force is large due to the presence of a predetermined amount or more of water in the water tank 4 and the movement release unit 37 is idle. . Therefore, when the amount of water in the aquarium 4 is less than a predetermined amount, the lever 35a moves the aquarium 4 forward. When the amount is greater than the predetermined amount, the lever 35a moves the aquarium 4 forward by the movement release unit 37. It is more preferable not to let this occur. Thereby, it can prevent that an overload is added to the water tank moving part 32, and it can prevent and can provide a highly reliable washing machine.

  Further, in a state where the lid 7 is opened and the water tub 4 and the washing / dehydrating tub 10 are moved in the front direction of the washing machine 1, the user can use a bucket or a commercially available bath water supply unit to detach the inside of the washing / dehydrating tub 10. It is also desirable that the movement release unit 37 releases the lever 35a from pushing the water tank 4 when the amount of water in the water tank 4 exceeds a predetermined amount by supplying water to the tank. Thereby, it can prevent that the water tank moving part 32 fails.

  According to this embodiment configured as described above, when the lid 7 is opened, the water tank 4 is moved forward, and when the lid 7 is closed, the water tank 4 is returned to the original position between the four suspension rods 2. By providing the water tank moving part 32 to be moved, when the user opens the lid 7, the water tank 4 moves in the front direction of the washing machine 1 and tilts forward. Therefore, when the user stands in a predetermined position and looks at the washing / dehydrating tub 10, it becomes easier to see the bottom of the washing / dehydrating tub 10, which has been difficult to see, and the user does not look into the washing / dehydrating tub 10. Since it can also be seen, it becomes easy to load the article 5 to be cleaned.

  Then, when the user puts the object to be cleaned 5 into the washing / dehydrating tub 10 moved in front of the washing machine 1 through the water tub 4, turns on the washing machine 1, presses the start button, and closes the lid 7. Since the arm portion 36 of the lid 7 loosens the wire 33 a and releases the lever 35 a from pushing the water tank 4, the water tank 4 moves to the original position between the four suspension rods 2. Since the object to be cleaned 5 is washed in that state, the same washing, rinsing and dehydrating performance as in the conventional case can be obtained during operation.

Further, after the operation is finished, when the user opens the lid 7 in order to take out the object 5 to be cleaned, the arm portion 36 of the lid 7 pulls the wire 33a and the lever 35a pushes the water tank 4 from the rear. It moves in the forward direction of the machine 1 and tilts forward. Therefore, the user can easily see all the inside of the washing and dewatering tub 10 only by standing at a predetermined position of the washing machine 1. Further, when the object to be cleaned 5 is taken out from the upper part of the washing / dehydrating tank 10, the object 5 to be cleaned in front of the bottom of the washing / dehydrating tank 10 can be easily removed without looking into the washing / dehydrating tank 10 greatly. So you can never forget to take it out and forget to dry it.

  At the same time, the back of the bottom of the washing / dehydrating tub 10 moves in front of the washing machine 1 and is inclined to the front side and rises and approaches the user. Therefore, the object to be cleaned can be taken out without extending the hand to the back of the bottom of the washing / dehydrating tub 10 as in the prior art.

  Therefore, it becomes easy to put in and out the article 5 to be cleaned in the washing machine, and the usability is improved. And since the motor etc. which require a power supply are not used for the water tank moving part 32, the washing machine which installation property does not fall or an energy usage-amount does not increase can be provided.

  Although the lever 35a rotates and pushes the water tank 4, the rod may extend to push the water tank 4, or the water tank 4 may be moved by pulling the front of the water tank 4. Further, the lever 35a may be provided at one center in the width direction of the washing machine so as to push one point at the center of the aquarium 4, or at two positions slightly shifted left and right from the center. There may be a plurality of points such as pressing a point, and the number is not limited.

  In addition, the washing / dehydrating tub 10 and the water tub 4 have a large space in the upper part for loading the object to be cleaned 5, and are equipped with heavy parts such as the drive unit 13, the speed reduction mechanism 14, and the rotating shaft 15 in the lower part. Moreover, since the cleaning object 5 is also deposited from the lower part, the lower part has a heavy structure. Therefore, the abutting part 35 of the water tank moving part 32 pushes or pulls on the upper part of the water tank 4 because the upper part of the water tank 4 is lighter than the lower part and the structure and operation of the hanging rod 2 cause washing and removal. The water tank 10 and the water tank 4 are more preferable to be inclined more easily on the front side.

  As shown in FIG. 3, the suspension rod 2 includes a damping member 8 having a spring 30 in order to suppress vibration of the water tank 4 during operation. Therefore, as shown in FIG. 6, when nothing is put in the washing / dehydrating tub 10 and the water tub 4, the force applied to the hanging rod 2 is the least, so the tub 4 has the upper surface at the top of the line A. It is held at the holding position. When the object to be cleaned 5 is put into the washing and dewatering tub 10 and water is supplied, the weight of the entire water tub 4 increases, so the spring 30 of the vibration damping member 8 is compressed to a predetermined weight. Then, the upper surface of the water tank 4 is lowered to the holding position of the line B. That is, the holding position of the water tank 4 moves up and down within the predetermined weight depending on the state in the water tank 4 within the width of (Line A-Line B).

  Therefore, the lever 35a of the water tank moving unit 32 may be configured to push the vicinity of the line B between the line A and the line B, which is the holding position of the water tank 4, at the upper part of the water tank 4. Thereby, when the lid 7 is opened, the operation of the lever 35a pushing the water tank 4 from the rear is the same, but when the water tank 4 is light, the water tank 4 exists at a position where the lever 35a pushes the water tank 4, so that the water tank 4 It can move in front of the washing machine 1. On the other hand, when the water tank 4 is heavier than a predetermined weight, the water tank 4 does not exist at the position where the lever 35a pushes the water tank 4, so that the water tank 4 does not move without being pushed, and the original space between the four suspension rods 2 does not move. Still in position. Therefore, since the lever 35a can be pushed only when the water tank 4 is not more than a predetermined weight, the structure can be simplified without adding parts such as the movement release portion 37, and the reliability of the lever 35a and the wire 33a can be improved. Can be increased.

Furthermore, as shown in FIGS. 1 and 4, the insertion port 6 can be formed up to the front upper portion of the washing machine 1 by arranging the operation unit 27 behind the lid 7. Accordingly, the width W between the front surface portion of the upper frame body 25 and the insertion port 6 can be reduced, and the height H of the front surface portion of the upper frame body 25 can be decreased. It becomes easy and usability can be further improved.

(Embodiment 2)
As a second embodiment, a configuration will be described in which the abutment portion is replaced with a lever and the water tank is held by a wire. FIG. 7 is a side cross-sectional view of the washing machine according to Embodiment 2 of the present invention, showing a state where the lid of the washing machine is closed. FIG. 8 is a plan sectional view of the washing machine in the present embodiment, and shows a state seen from above when the lid is closed. FIG. 9 is a side sectional view of the washing machine in the present embodiment, and shows a state where the lid of the washing machine is opened. FIG. 10 is a plan sectional view of the washing machine in the present embodiment, and shows a state seen from above when the lid is opened.

  In the present embodiment, as shown in FIG. 7 to FIG. 10, the water tank moving part 32 is, as the connecting part 33, the arm part 36, the wire 33 a, the pulley 34, and the abutting part 35 formed integrally with the lid 7. And have. The difference from the first embodiment is that, in the contact portion 35, instead of the lever 35a, the wire 33a of the connecting portion 33 is extended as it is, and the water tank 4 is held by one wire 33a. It is.

  Two arm portions 36 are provided at the left and right ends of the lid 7, and the wire 33 a is connected so as to connect the two arm portions 36. Pulleys 34 are also provided at two places on the left and right, and second pulleys 38 are provided at two places on the left and right below the pulley 34. Further, third pulleys 39 are provided at two right and left portions on the upper left and right side surfaces of the housing 3, and a wire receiving portion 40 is provided at the center of the rear portion of the water tank 4 at substantially the same height as the third pulley 39.

  The wire 33a penetrates the wire receiving portion 40 and is held by the wire receiving portion 40 so as to be movable in the vicinity of the center of the entire length. And it is spanned so that the rear part of the water tank 4 may be held via the left and right third pulleys 39, and connected to the arm part 36 via the second pulley 38 and the pulley 34. Thereby, the rotational movement of the lid 7 is the movement of the arm portion 36 formed integrally with the lid 7. This movement of the arm portion 36 pulls the wire 33a connected to the arm portion 36 and improves the slidability of the wire 33a via the pulley 34, the second pulley 38 and the third pulley 39. It is transmitted to the rear part of the water tank 4 provided with 40.

  Specifically, as shown in FIGS. 7 and 8, when the lid 7 is closed, the wire 33a is in a slack state. 9 and 10, when the lid 7 is opened, the arm portion 36 formed by extending the lid 7 rotates in the direction of pulling the wire 33a. Then, the wire 33a is pulled to hold the water tank 4 and push it from the rear. As a result, the water tank 4 moves in the forward direction of the washing machine 1.

  On the other hand, when the lid 7 is closed, the arm portion 36 rotates in the direction of loosening the wire 33a. Then, the wire 33a is released and the pushing of the water tank 4 is released, and the water tank 4 moves to the original position between the four suspension rods 2. Thus, by pulling or loosening the wire 33 a with the arm portion 36, the tension of the wire 33 a is transmitted to the water tank 4 and moved in the front-rear direction while embrace the upper part of the water tank 4.

  As described above, if the abutting portion 35 is configured such that the wire 33a embraces the rear upper part of the water tank 4 in an arc shape, the lever 35a can be replaced. When the lever 35a is used to push the water tank, the load is concentrated at one or two points where the water tank 4 is pushed. However, if the water tank 4 is embraced by the wire 33a, the part pushing the water tank 4 becomes a linear or belt-shaped load. Can be suppressed, and the water tank 4 can be tilted reliably.

In addition, since the wire 33a is in a sagging state when the lid 7 is closed, no extra force is applied flexibly to the shaking of the water tank 4 during operation. Further, even when a load exceeding a predetermined value is applied, a simpler configuration can be obtained by configuring a part of the wire 33a with an elastic member such as a spring.

  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.
