Description

Washing machine

The present invention relates to a washing machine that puts and removes objects to be cleaned from the upper surface of a housing.

Conventionally, this type of washing machine has a configuration as shown in FIG. 11 (see, for example, Patent Document 1).

FIG. 11 is a cross-sectional view of the conventional washing machine 100 as viewed from the side.

In FIG. 11, the washing machine 100 includes a housing 101 configured in a substantially rectangular shape, and a water tank 102 configured in a substantially cylindrical shape is provided inside the housing 101 as a hanging rod. 103 is suspended. Inside the water tank 102, a washing and dewatering tank 104 configured in a substantially cylindrical shape is rotatably included.

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 its bottom. The housing 101 has an opening on the top surface thereof for opening and removing the object 115 and a lid 106 for opening and closing the opening. Further, a control device 107 that executes a series of steps such as washing, rinsing, and dehydration, and an operation unit 108 for setting an operation course and the like are provided at the front portion of the lid 106.

FIG. 12 is a plan view of the reinforcing support portion 109 provided at the four corner upper portions 101a of the housing 101 in the conventional washing machine 100. FIG.

The reinforcing support portions 109 are provided at the upper corners 101a of the casing 101, support the suspension rod 103, and also serve as reinforcement of the casing 101. The four suspension rods 103 are arranged 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 the water tank 102 is suspended 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 103 provided with a vibration damping member 110 in the conventional washing machine 100. FIG.

The damping member 110 includes a damper 112 and a spring 113 inside a damper case 111 whose upper surface is spherical, and suppresses the vibration of the water tank 102 generated during operation of the washing machine 100 from being transmitted to the casing 101. is doing. As shown in FIG. 12 and FIG. 13, the suspension rod 103 is disposed at the upper end of the suspension rod 103 by the spherical support portion 114 being in spherical contact with the spherical portion 109 a of the reinforcement support portion 109.

FIG. 14 is a cross-sectional view of the vicinity of the damper support portion 102 a formed in the water tank 102 in the conventional washing machine 100.

As shown in FIGS. 13 and 14, the damper support portion 102a and the damping member 110 are configured to be in spherical contact. Due to the upper and lower spherical contact configurations, even if the water tank 102 is swung around by vibration, an unreasonable force is not applied to the hanging rod 103 or the casing 101.

However, the configuration of the conventional washing machine 100 as shown in FIG. 11 has the following problems.

That is, since the water tank 102 is suspended by the four suspension rods 103 so that it can swing freely in the washing machine 100, the water tank 102 is placed at the center of the four suspension rods 103 when stopped. To position. 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 the water tank 102 exists in the position away from the front surface of the washing machine 100.

FIG. 15 is a cross-sectional view of the washing and dewatering tub 104 of the conventional washing machine 100 as seen from the side when viewed by the user.

That is, as shown in FIG. 15, for example, it is assumed that a woman with a height of about 150 cm to 155 cm looks inside the washing / dehydrating tub 104 while standing in front of the washing machine 100. In this case, the object to be cleaned 115a in front of the bottom of the washing and dewatering tub 104 cannot be seen and may be forgotten. In order to prevent this forgetting, the user needs to look deeply into the washing / dehydrating tank 104. Further, since the distance to the bottom of the washing / dehydrating tub 104 is far from the user, the user needs to extend his hand greatly, and it is difficult to take out the object 115b to be cleaned.

On the other hand, in washing, the number of washing is increasing, and the capacity of the washing and dewatering tank 104 is demanded. However, in order to cope with an increase in capacity without increasing the installation area of the washing machine 100, it is necessary to increase the depth of the washing and dewatering tank 104. As a result, 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 becomes farther from the user. It may be difficult to remove.

In order to solve such a problem, a washing machine 200 is disclosed in which the water tank 102 is inclined when the object 115 to be cleaned such as clothes is taken out or put in (for example, Patent Document 2). See).

FIG. 16 is a schematic diagram of an internal configuration viewed from the side of a conventional washing machine 200.

FIG. 16 shows a state where the water tank 202 is inclined. The washing machine 200 includes a housing 201, a water tank 202 disposed in the housing 201, a suspension rod 203 that supports the water tank 202, a tilting unit that tilts the water tank 202 with the tilting fulcrum 220a as a fulcrum, a control unit, have.

The washing machine 200 is configured to be able to change the inclination angle of the water tank 202 in accordance with each process from when clothes are put in to when the washed and dehydrated clothes are taken out. The tilting unit is configured by a tilting motor 221 having a pinion 222 fixed to a rotating shaft attached to a horizontal base 219, a rack 223 disposed on the tilting base 220 so as to be movable up and down, and meshing the pinion 222 and the rack 223. ing.

Thus, when the rack 223 pushes up the tilting table 220 by the rotation of the tilting motor 221, the tilting table 220 is tilted about the tilting fulcrum 220a. The washing machine 200 includes, for example, a mechanism in which clothes are washed with the water tank 202 tilted, dehydrated with the water tank 202 standing upright, and clothes are taken out with the water tank 202 tilted.

However, in such a configuration of the washing machine 200, since the gear is combined with the tilting motor 221, when the washing machine 200 becomes larger, the installation property is lowered or the amount of energy used for tilting is increased. Has a problem.

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

(First embodiment)
FIG. 1 is a cross-sectional view seen from the side of the washing machine 1 according to the first embodiment of the present invention.

In FIG. 1, the washing machine 1 includes a casing 3 constituting an outer shell, and a water tank 4 supported by four hanging rods 2 inside the casing 3. The housing 3 has, on the upper surface thereof, a loading port 6 for taking in and out an object to be cleaned 5 such as clothes, and a lid 7 for opening and closing the loading port 6.

Inside the water tank 4, a washing and dewatering tank 10 having an opening on the upper side and storing an object to be cleaned 5 is rotatably provided. A pulsator 11 is rotatably disposed at the bottom of the washing and dewatering tub 10, and a lower blade 12 is provided integrally with the pulsator 11.

The drive unit 13 such as a motor drives at least one of the pulsator 11 and the washing and dewatering tub 10 via the speed reduction mechanism 14 and the respective rotation shafts 15. The lint water channel 16 is provided so as to reach from the pump chamber 17 on the outer periphery of the lower blade 12 of the pulsator 11 to the upper part of the washing and dewatering tub 10. The lint water channel 16 includes a lint filter 18 that can be attached and detached at the top, and collects lint such as lint and dust contained in the washing water and the rinsing water.

The drainage part 19 is comprised from the drainage valve 20 and the drainage hose 21, and drains the wash water and rinse water in the water tank 4. FIG. The drainage hose 21 is held by the housing 3, but is formed of a bellows or a telescopic hose in order to cope with a state in which the water tank 4 sways during dehydration.

Therefore, even if the water tank 4 moves in the front direction of the washing machine 1, the drainage hose 21 can be deformed without being bent, and the water tank 4 repeatedly moves in the front-rear direction, thereby opening a hole. This is not the case (see FIG. 4). Moreover, the water supply valve 22 provided in the upper part supplies the tap water used as washing water and rinse water in 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 drive unit 13 spins 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 to dehydrate the article 5 to be cleaned. When the washing / dehydrating 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 / dehydrating tub 10, and the washing water or the rinsing water contained in the object to be cleaned 5 is subjected to the centrifugal force. Moves to the water tank 4 through the drain hole 10a. Further, a fluid balancer 24 for reducing vibration during dehydration is provided on 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, there is provided an operation unit 27 having a setting unit for setting the washing operation and a display unit for displaying the operation state and the like. In FIG. 1, an example in which the operation unit 27 is disposed behind the lid 7 is shown. However, if it is a place that does not affect the usability of the operation unit 27, Or you may arrange | position to the right. 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. When the lid 7 is closed, the insertion port 6 is covered.

Next, the support of the water tank 4 will be described.

FIG. 2A is a cross-sectional view of the reinforcing support portion 28 and the suspension rod support portion 29 of the washing machine 1 according to the first embodiment of the present invention, and FIG. 2B is a plan view of the reinforcing support portion 28. FIG. 3 is a cross-sectional view of the vicinity of a damper support portion 4 a formed in the water tub 4 of the washing machine 1.

The reinforcement support portion 28 is provided at the upper corners 3 a of the housing 3, supports the suspension rod 2, and also serves to reinforce the housing 3. The four suspension rods 2 that support the water tank 4 are arranged on the four corner upper portions 3a of the housing 3 via the reinforcing support portions 28, and are inclined with respect to the vertical direction to improve the damping effect. The upper reinforcing support portion 28 side is configured to spread outward from the lower portion. The four suspension rods 2 are provided with a suspension rod support portion 29 at the upper end and a damping member 8 at the lower end. The four suspension rods 2 suspend and support the water tank 4 through four damper support portions 4 a formed at the lower part of the water tank 4.

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 formed in a spherical shape. The vibration damping member 8 suppresses the vibration of the water tank 4 generated during the operation of the washing machine 1 from being transmitted to the housing 3.

The damping member 8 and the damper support 4a are also in spherical contact. Since the water tank 4 is suspended at the center by the four suspension rods 2, it can be freely swung around. In addition, due to the upper and lower spherical contact structures, even if the water tank 4 is swung around by vibration, an unreasonable force is not applied to the hanging rod 2 and the housing 3.

Next, the water tank moving part 32 of the washing machine 1 in the present embodiment will be described with reference to FIGS. 1 and 4.

FIG. 4 is a cross-sectional view of washing machine 1 according to the present embodiment as viewed from the side where water tank 4 has moved.

At the rear of the washing machine 1, a water tank moving unit 32 for moving the water tank 4 back and forth is provided. The water tank moving part 32 is configured by 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. As described above, since there is no motor or the like that needs a power source for driving 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 includes movement and rotation depending on the portion of the lid 7, and the connecting portion 33 may use any of these movements. Moreover, the structure of the connection part 33 may use the transmission structure by a link mechanism or a gear, and may use the transmission structure by a wire or a belt, and is not specifically limited. Moreover, as the contact part 35, the structure which pushes the water tank 4 from back like this Embodiment may be sufficient, 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, the rear of the water tank 4 may be held by a wire, as will be described later, in addition to being pushed by the lever 35a as in the present embodiment. In any configuration, the configuration is not limited to a specific configuration 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 has an arm portion 36 formed integrally with the lid 7, a wire 33a and a pulley 34, and the contact portion 35 has a lever 35a. Thereby, the rotational movement of the lid 7 is converted into 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 by the arm portion 36, the lever 35a is driven, the upper part of the water tank 4 is pushed, and the water tank 4 is 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 33a. 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. And when the lid | cover 7 is closed, the arm part 36 will rotate in the direction which loosens the wire 33a. Therefore, the lever 35a returns to the original position, the pressure on the water tank 4 is released, and the water tank 4 moves to the original position between the four suspension rods 2.

FIG. 5 is a schematic diagram showing the movement of the water tub 4 of the washing machine 1 in the first embodiment of the present invention.

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, when the water tank 4 is moved forward so that the suspension rod 2 moves circularly at an angle θ by applying a pressing force F, the front damper support portion 4a is moved rearward and rearward. The damper support portion 4a on the side moves in the front-up direction. Thereby, as shown with the dashed-two dotted line in FIG. 5, the water tank 4 inclines to the front side. 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 damping member 8 to contract and the rear damping member 8 to extend. Thereby, the inclination to the front side of the water tank 4 is promoted.

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, and the longer the distance, the larger the inclination angle due to the configuration of the four suspension rods 2. Is possible. However, since the dimension of the washing machine 1 in the front-rear direction becomes large at that time, the influence on the installation property must be taken into consideration.

It is desirable that the insertion port 6 is formed in an optimal shape in which the user can most easily put in and out the cleaning object 5 at the position where the water tank 4 has 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 match 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 in a state where the lid 7 is closed needs to be arranged at a position where it does not hit even if the water tub 4 swings during the operation of the washing machine 1. As a result, the lever 35a and the water tank 4 collide with each other, noise is generated, the lever 35a or the water tank 4 is broken, or the swing performance of the water tank 4 changes to change the vibration performance. Can be prevented. Therefore, the lever 35a can be prevented from adversely affecting the operation of the washing machine 1, and the washing performance equivalent to the conventional one can be obtained.

Based on the above configuration, the operation of the washing machine 1 of the present embodiment will be described.

When the washing machine 1 is left with the lid 7 closed, the arm portion 36 of the lid 7 loosens the wire 33a and the lever 35a does not push the water tank 4. Therefore, the water tank 4 is located at substantially the center between the four suspension rods 2. As a result, the water tank 4 is in a state equivalent to that of a conventional washing machine, and the water tank 4 and parts attached to the water tank 4 are loaded with the same load as in the conventional case, so that no special problem occurs.

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. Thereby, the water tub 4 moves in the front direction of the washing machine 1 and is inclined forward by 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 the user can see the front of the bottom without having to look into the washing / dehydrating tub 10 largely, the user can easily put the article 5 to be cleaned. Here, the predetermined position is, for example, a position as shown in FIG. 15 where a woman with a height of about 150 cm to 155 cm looks inside the washing / dehydrating tub 10 while standing in front of the washing machine 1. is doing.

Next, the user puts an object to be cleaned 5 such as clothes into the washing / dehydrating tub 10 moved to the front of the washing machine 1 together with the water tub 4, turns on the washing machine 1, and starts the operation unit 27. Press. Then, the pulsator 11 is rotated in both forward and reverse directions by the drive unit 13 and the amount of the object to be cleaned 5 is detected. Then, the washing machine 1 displays a 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, the lid lock is activated and the lid 7 is prevented from opening. At the same time, the arm portion 36 of the lid 7 loosens the wire 33 a and the lever 35 a does not press the water tank 4. Therefore, the water tank 4 and the washing / dehydrating tank 10 are returned to the original positions between the four hanging 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, the pulsator 11 rotates and a washing step for washing the article 5 to be cleaned is performed. 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 number of revolutions 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. A first dehydration step is performed.

When the first dehydration 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 rotates, 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. Then, the washing and dewatering tub 10 is rotated at a predetermined number of rotations by the drive unit 13, and the second dewatering 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 item to be cleaned 5 is washed in this state, washing, rinsing, and dewatering performance equivalent to those in the prior art can be obtained during operation.

After the operation is finished, the user opens the lid 7 to take out the object 5 to be cleaned. Then, the arm portion 36 of the lid 7 pulls the wire 33 a and the lever 35 a pushes the water tank 4. Thereby, the water tub 4 moves in the front direction of the washing machine 1 and is inclined forward by 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 taken out from the upper part of the washing / dehydrating tank 10 in order, the washing / dehydrating tank 10 can be removed without looking into the washing / dehydrating tank 10 in the same manner as when the objects to be cleaned 5 are introduced. The object 5 to be cleaned in front of the bottom of the water tank 10 can be easily seen. Therefore, the user forgets to take out the object 5 and forgets to dry it.

At the same time that the water tub 4 is tilted forward, the back of the bottom of the washing / dehydrating tub 10 is also moved in the forward direction of the washing machine 1 and rises as the washing / dehydrating tub 10 is tilted. That is, since the bottom of the washing / dehydrating tub 10 is also close to the user, the user bends the object to be cleaned 5 that could not be taken out until reaching the back of the bottom of the washing / dehydrating tub 10. It can be taken out without reaching.

When the user closes the lid 7 after taking out the article 5 to be cleaned, the arm portion 36 of the lid 7 loosens the wire 33a, and the lever 35a releases the pressure on the water tank 4. Therefore, the water tub 4 and the washing / dehydrating tub 10 are moved to their original positions between the four suspension rods 2.

In addition, there is a washing machine in the water tank 4 that can store water of, for example, 60 liters or more. In such a washing machine, it is assumed that the lid 7 can be opened temporarily after the washing step or the rinsing step. In such a case, the pressing force required for the lever 35a to push the water tank 4 becomes very large. In some cases, the lever 35a is damaged or the wire 33a is cut, so that the lever 35a There is a possibility that the water tank 4 cannot be pushed.

In order to cope with such a situation, it is desirable that the lever 35a is provided with a movement release unit 37. As a result, when the necessary pressing force is large due to the presence of a predetermined amount or more of water in the water tank 4, the lever 35a forcibly pushes the water tank 4 by rotating the movement release portion 37 or the like. Make sure there is nothing. Furthermore, when the amount of water in the aquarium 4 is less than or equal to a predetermined amount, the lever 35a moves the aquarium 4 in the forward direction. When the amount is greater than the predetermined amount, the lever 35a moves the aquarium 4 in the forward direction by the movement release unit 37. It is more preferable if it is configured so that it does not occur. Thereby, it can prevent that an overload is added to the water tank moving part 32, and it can prevent, and the washing machine 1 with high reliability can be provided.

In addition, while the lid 7 is opened and the water tub 4 and the washing / dehydrating tub 10 are moved in the forward direction of the washing machine 1, the user can use a bucket or a commercially available bath water supply unit to wash and dehydrate the tub. A case is assumed where the amount of water in the water tank 4 is equal to or greater than a predetermined amount by supplying water into the water tank 10. In such a case, it is desirable that the movement release unit 37 be configured so that the pressure applied to the water tank 4 by the lever 35a is released. Thereby, it can prevent that the water tank moving part 32 fails.

According to the present embodiment, the washing machine 1 moves the water tank 4 forward when the lid 7 is opened, and moves the water tank 4 to the original position between the four suspension rods 2 when the lid 7 is closed. A water tank moving unit 32 is provided. For this reason, when the user opens the lid 7, the water tub 4 moves in the forward 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 the front side of the bottom can also be seen, it becomes easy to load the object 5 to be cleaned.

Here, the user puts an 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 puts the lid 7 on. Assume the case of closing. In this case, the arm portion 36 of the lid 7 loosens the wire 33 a and releases the pressing of the lever 35 a against the water tank 4, so that the water tank 4 moves to the original position between the four suspension rods 2. Since the item to be cleaned 5 is washed in this state, washing, rinsing, and dewatering performance equivalent to those in the prior art can be obtained during operation.

Furthermore, after the operation is completed, 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 33a, and the lever 35a pushes the water tank 4 from the rear. Therefore, the water tank 4 moves in the front direction of the washing machine 1 and tilts forward. Therefore, 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. 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.

Also, simultaneously with the movement of the water tub 4 to the front side of the washing machine 1, the bottom of the washing and dewatering tub 10 also moves to the front side of the washing machine 1, and tilts upward and approaches the user. Therefore, the user can easily reach the back of the bottom as the back of the bottom of the washing and dewatering tub 10 moves in front of the washing machine 1 and rises. That is, the user can take out the article 5 to be cleaned at the bottom of the washing / dehydrating tub 10 without reaching out as in the prior art.

As described above, according to the washing machine 1 of the present embodiment, it becomes easy to put in and out the article 5 to be cleaned, and the usability can be improved. Moreover, since the motor etc. which require a power supply are not used as the water tank moving part 32, the washing machine 1 which installation property does not fall or an energy usage-amount does not increase can be provided.

In the present embodiment, the lever 35a rotates to push the water tank 4, but the present invention is not limited to this configuration. For example, the structure which a rod extends and pushes the water tank 4 may be sufficient, and the structure which pulls the front of the water tank 4 and moves the water tank 4 may be sufficient. In addition, the lever 35a may be provided at one center in the width direction of the washing machine 1 so as to push one point at the center of the water tank 4, or at a position slightly shifted from the center to the left and right respectively. A plurality of two locations may be provided by pressing two points, and the present invention is not limited to the number of levers 35a.

Further, the upper part of the washing / dehydrating tub 10 and the water tub 4 has a large space for the object 5 to be washed in, and heavy parts such as the drive unit 13, the speed reduction mechanism 14, and the rotating shaft 15 are provided in the lower part. ing. Moreover, since the cleaning object 5 is also deposited from the lower part, the lower part has a heavy structure. Therefore, pushing or pulling the upper part of the water tank 4 by the abutting part 35 of the water tank moving part 32 means that the upper part of the water tank 4 is lighter than the lower part and the structure and operation of the suspension rod 2 The cum dewatering tank 10 and the water tank 4 are preferable because they are more easily inclined to the front side.

FIG. 6 is a diagram showing a holding position of the water tank 4 when the weight of the water tank 4 of the washing machine 1 in the first embodiment of the present invention is different.

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 smallest, so It is held at the uppermost holding position.

Then, when the object to be cleaned 5 is put into the washing and dewatering tank 10 and water is supplied, the weight of the entire water tank 4 increases, and the spring 30 of the damping member 8 is compressed. When the weight of the water tank 4 reaches a predetermined weight, 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 changes vertically between the line A and the line B within a predetermined weight range depending on the state in the water tank 4.

Therefore, it is desirable that the lever 35a of the water tank moving unit 32 is configured to push the line A and the line B as the holding position of the water tank 4, particularly in the vicinity of the line B, 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. However, when the water tank 4 is light, the water tank 4 exists at the position where the lever 35a pushes. Can be moved to the front side of the washing machine 1. On the other hand, when the water tank 4 is heavier than the predetermined weight, the water tank 4 does not exist at the position where the lever 35a is pushed, so the water tank 4 does not move without being pushed, and the original position between the four suspension rods 2 It is in. Therefore, the lever 35a can push the water tank 4 only when the water tank 4 is below a predetermined weight. Therefore, it is possible to simplify the configuration without adding parts such as the movement release unit 37, and it is possible to improve the reliability of the lever 35a, the wire 33a, and the like.

Furthermore, as shown in FIG. 1 and FIG. 4, the insertion port 6 can be formed up to the front upper part of the washing machine 1 by arranging the operation unit 27 behind the lid 7. Thereby, the width W (refer FIG. 1) of the front part of the upper frame 25 and the insertion port 6 can be made small. Furthermore, since the height H of the front surface portion of the upper frame 25 can be lowered, it becomes easier to put in and out the article to be cleaned 5 and the usability can be further improved.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. In the present embodiment, a configuration will be described in which the abutment portion 35 is configured to embrace a water tank with a wire 33a instead of the lever 35a.

FIG. 7 is a cross-sectional view seen from the side of the washing machine 1 in the second embodiment of the present invention. FIG. 7 shows a state in which the lid 7 of the washing machine 1 is closed. FIG. 8 is a schematic diagram showing an internal configuration viewed from above the washing machine 1 in the second embodiment of the present invention. FIG. 8 shows a state viewed from above when the lid 7 is closed. FIG. 9 is a cross-sectional view seen from the side of the washing machine 1 according to the second embodiment of the present invention. FIG. 9 shows a state where the lid 7 of the washing machine 1 is opened. FIG. 10 is a schematic diagram illustrating an internal configuration viewed from above the washing machine 1 according to the second embodiment of the present invention. FIG. 10 shows a state viewed from above when the lid 7 is opened.

In the present embodiment, as shown in FIG. 7 to FIG. 10, the water tank moving part 32 includes, as a connecting part 33, an arm part 36 formed integrally with the lid 7, a wire 33a, and a pulley 34 (first 1 pulley) and an abutting portion 35. The present embodiment is different from the first embodiment in that, in the contact portion 35, the wire 33a of the connecting portion 33 is used as it is instead of the lever 35a, and the water tank 4 is used by one wire 33a. Is configured to be embraced.

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

The wire 33 a passes through the wire receiving portion 40, and the vicinity of the center of the entire length is held movably by the wire receiving portion 40. The wire 33a is hung so as to embrace the rear part of the water tank 4 via the left and right third pulleys 39, and is connected to the arm part 36 via the second pulley 38 and the pulley 34. Yes. With such a configuration, first, the rotational movement of the lid 7 is converted into the movement of the arm portion 36 formed integrally with the lid 7. Then, the 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 the wire receiver 40.

Specifically, as shown in FIGS. 7 and 8, when the lid 7 is closed, the wire 33a is in a slack state. As shown in FIGS. 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. If it does so, the wire 33a will be pulled, the water tank 4 will be held, and it will push from back. 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 33 a is loosened and the pressure on 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 can be transmitted to the water tank 4 and moved in the front-rear direction while embedding the upper part of the water tank 4.

Thus, if the contact portion 35 is configured such that the wire 33a embraces the rear upper part of the water tank 4 in an arc shape, a configuration that replaces the lever 35a can be realized. When pushing the water tank 4 with the lever 35a, the part where the water tank 4 is pushed becomes one point or two points, and the load concentrates. However, if the water tank 4 is held by the wire 33a, the part pushing the water tank 4 becomes a line or a band. The load can be prevented from being concentrated. Therefore, the water tank 4 can be tilted reliably.

In addition, when the lid 7 is closed, the wire 33a is in a slack state, so that it can flexibly cope with the shaking of the water tank 4 during operation, and no extra force is applied. Further, as a countermeasure when a load exceeding a predetermined value is applied, a simpler configuration can be realized by configuring a part of the wire 33a with an elastic member such as a spring.

As described above, the washing machine 1 shown in each embodiment has, on the upper surface, the housing 3 having the insertion port 6 for taking in and out the article to be cleaned 5 and the opening above, and the article to be cleaned 5. A washing / dehydrating tub 10 for storing the water and a water tub 4 in which the washing / dehydrating tub 10 is rotatably installed are provided. The washing machine 1 also has a suspension rod 2 that supports the water tank 4, a lid 7 that opens and closes the inlet 6, and the water tank 4 is moved forward when the lid 7 is opened, and the water tank 4 when the lid 7 is closed. And a water tank moving part 32 for moving the water to the original position.

With such a configuration, when the user opens the lid 7, the water tank 4 is moved in the forward direction of the washing machine 1 by the water tank moving unit 32. Moreover, the position which supports the water tank 4 in the hanging rod 2 moves a front side hanging rod to the front lower side, and a rear side hanging rod moves to the front upper side. Therefore, the water tank 4 and the washing and dewatering tank 10 inside thereof are inclined forward. Therefore, the user can easily see the object to be cleaned 5 in front of the bottom of the washing / dehydrating tank 10 without looking into the washing / dehydrating tank 10 and never forget to take it out. Further, the user can easily reach his / her hand by the amount that the bottom of the washing / dehydrating tub 10 moves to the front side of the washing machine 1, and can easily take out the article 5 to be cleaned. Therefore, when the user stands in a predetermined position and looks at the washing / dehydrating tub 10, it becomes easier to see the front of the bottom of the washing / dehydrating tub 10, which has been difficult to see, and the bottom of the bottom can be easily reached. It is easy to put in and out the object 5 and the usability is improved.

Further, the water tank moving part 32 has a contact part 35 that contacts the water tank 4 and a connecting part 33 that transmits the movement of the lid 7 to the contact part 35, and the water tank 4 is connected to the water tank by the contact part 35. 4 may be configured to be inclined by applying a force to the upper portion thereof.

Thereby, since the water tank moving part 32 does not use a motor or the like for driving, it is possible to realize a configuration in which the installation property is not reduced and the amount of energy used is not increased.

Moreover, the water tank moving part 32 may have a movement releasing part 37 that releases the pressure on the water tank 4 when a predetermined force or more is applied to the contact part 35.

Thus, when there is a predetermined amount or more of water in the water tank 4, the water tank moving unit 32 cannot push the water tank 4 by the movement release unit 37. Therefore, when the amount of water in the aquarium 4 is less than or equal to the predetermined amount, the aquarium moving unit 32 moves the aquarium 4 in the forward direction. It can be prevented from moving forward. Thereby, it can prevent that an overload is added to the water tank moving part 32, and it can prevent, and the washing machine 1 with high reliability can be provided.

Further, in the water tank moving part 32, the connecting part 33 may be constituted by a wire 33a, and the contact part 35 may be constituted by a lever 35a.

Thereby, since the water tank moving part 32 does not use a motor or the like for driving, it is possible to realize a configuration in which the installation property is not lowered and the amount of energy used is not increased.

The suspension rod 2 has a vibration damping member 8 that suppresses transmission of vibration from the water tank 4 and lowers the holding position of the water tank 4 when the amount of water in the water tank 4 and the object to be cleaned 5 increases. In the height direction of the water tank 4, the contact portion 35 has the water tank 4 when the weight of the water tank is equal to or less than a predetermined weight and does not exist when the weight of the water tank is equal to or greater than the predetermined weight. It may be configured to push the position in the horizontal direction.

With such a configuration, when there is nothing in the washing / dehydrating tub 10 and the water tub 4, the force applied to the suspension bar 2 is the least, so the water tub 4 is held at the uppermost holding position. And when water is supplied to the water tank 4 and the weight of the water tank 4 increases, the holding position of the water tank 4 falls. That is, the water tank 4 moves up and down depending on the state in the water tank 4. Therefore, when the water tank 4 is light, the water tank 4 is present at a position where the abutting portion 35 of the water tank moving unit 32 pushes the water tank 4, so that the water tank 4 can be moved to the front side of the washing machine 1. On the other hand, when the water tank 4 is heavy, since the water tank 4 does not exist at the position where the abutting portion 35 pushes the water tank 4, the water tank 4 does not move and remains at the original position between the four suspension rods 2. . Therefore, with such a configuration, the abutting portion 35 can be pushed only when the water tank 4 is not more than a predetermined weight, so that it can be easily configured without adding parts such as the movement release portion 37 and the like. The reliability of the moving part 32 can be improved.

Further, the water tank moving part 32 may have a configuration in which the connecting part 33 and the contact part 35 are constituted by one wire 33a.

With such a configuration, the portion that pushes the water tank 4 with the wire 33a becomes a line or a band, and the concentration of the load can be suppressed and the water tank 4 can be tilted reliably.

Alternatively, a configuration may be provided that further includes an operation unit 27 that is arranged behind the lid 7 and that sets the washing operation.

Thereby, since there are no parts in the front upper part of the washing machine 1, the insertion port 6 can be formed up to the front upper part. Therefore, the width between the front surface portion of the upper frame body 25 and the insertion port 6 can be reduced, and the height of the front surface portion of the upper frame body 25 can be decreased. Therefore, it becomes easier to put in and out the article to be cleaned 5 and the usability can be further improved.

As described above, according to the present invention, the ease of installation can be facilitated and the usability can be improved without lowering the installation property or increasing the amount of energy used. There is an effect. Therefore, the present invention can be applied to uses such as a household washing machine and a commercial washing machine in which an object to be cleaned is taken in and out from the upper surface of the housing, and is useful.
