Description

washing machine

The present invention relates to a drum type washing machine and a drum type washing and drying machine.

The drum type washing machine is an anti-vibration support in which the outer tank retaining water in the casing, and the washing and dewatering tank in the outer tank, that is, the drum is rotatably supported by the motor. During the dehydration process, the washing of the laundry contained in the drum is performed by rotating the drum at a high speed. At this time, if the laundry in the drum is biased to a certain portion (unbalanced), the vibration force is generated by the unevenness of the centrifugal force. By this oscillating force, the vibration system including at least the drum and the outer tub and the motor vibrates, causing (causing) vibration and noise. Here, such a drum type washing machine is provided with an anti-vibration member that supports the outer tub from below, and suppresses vibration of the vibration system.

When the rotating shaft of the drum of the drum type washing machine is a substantially horizontal washing machine, the center of gravity of the vibration system moves in the front-rear direction before and after the laundry such as clothes is put into the drum. In other words, the position of the center of gravity of the vibration system and the positional relationship of the vibration-proof member are changed by the amount of load held by the outer tank such as the laundry or the water. Moreover, the position of the center of gravity of the vibration system is located in the anti-vibration When the member is further forward or rearward, the load is increased, and the distance between the center of gravity of the vibration system and the position of the vibration-proof member is longer, and the moment force composed of the product of the load amount and the distance is increased. The groove is easy to tilt. When the inclination of the outer groove becomes large, the vibration state does not change, and the gap relationship between the outer groove and the frame also changes. As a result, the conditions in which the outer tank and the frame are easily collided also change, and the vibration and the noise are excessively large depending on the amount of load, and the structure and control for preventing the use thereof are complicated. Therefore, in order to prevent excessive vibration and noise, it is necessary to prevent the outer groove from being excessively inclined due to the load amount, that is, the stability of the vibration system for the load amount is necessary.

Here, Patent Document 1 of the prior art describes that "the supported portion composed of a water tank, a drum, a motor, or the like is supported by one on the front side of the center of gravity and two on the rear side. The self-supporting support can be stably and stably, and the vibration in the front-rear direction can be more preferably suppressed by tilting the three suspensions to the front and rear.

Further, in Patent Document 2, "the first anti-vibration member and the second anti-vibration member that support the water tank are separated by a predetermined interval in the front-rear direction. Therefore, the water tank is in the front-rear direction by the first (1) The anti-vibration member and the second anti-vibration member are stably supported. Further, the predetermined interval between the first anti-vibration member and the second anti-vibration member is in a no-load state including the inner water-containing tank and the washing tank. The center of gravity of the center of gravity and the rated load state is preferably in a range of the center of gravity of the washing machine in the no-load state and when the washing machine is operated in the rated load state, even if the center of gravity of the system moves in the front-rear direction. In this case, since the center of gravity is located between the first vibration isolating member and the second vibration isolating member, it is possible to suppress the complexity of the vibration of the system. "."

However, the technique disclosed in Patent Document 1 is to support the outer tank by the three vibration isolating members in order to improve the stability of the vibration system. However, since the vibration isolating member is more than two washing machines, the cost of the vibration isolating member is Further, the cost of the washing machine has an increased problem. Therefore, the above-described Patent Document 1 is not preferable in a configuration in which it is not necessary to increase the number of vibration-proof members and to improve the stability of the vibration system.

In the above-mentioned Patent Document 2, the two vibration isolating members that are disposed at predetermined intervals in the front-rear direction are included in the center of gravity of the vibration system at the time of the lightest no-load. The mode is set to prevent the posture of the outer groove from changing. However, in this configuration, the amount of movement of the center of gravity of the vibration system caused by the load amount increases as the distance between the two vibration isolating members increases. In other words, the center of gravity of the vibration system at the time of the maximum load and the distance between the vibration-proof members disposed rearward than the center of gravity of the vibration system at the time of no load increase. As a result, at the maximum load, the load applied to the front side anti-vibration member among the two anti-vibration members is more vibration-proof than the other. The member is larger so that the front end of the outer groove is inclined downward. In particular, when the capacity of the drum is increased, there is a lot of extra space in front of the casing having the moving line of the human body. Therefore, by moving the drum in the front-rear direction, the center of gravity of the vibration system caused by the load is generated. The amount of movement tends to become large. Therefore, in the case of the large-capacity drum, Patent Document 2 has an insufficient problem with the stability of the vibration system of the load amount.

An object of the present invention is to provide a washing machine which does not require an increase in the number of anti-vibration members even for a large-capacity drum, and can improve a vibration system including at least a drum and an outer tank and a motor for a change in load amount of laundry, water, or the like. Stability.

In order to solve the above problems, a washing machine includes: an outer tub that retains water, and a washing and dewatering tank rotatably provided in the outer tub, that is, a drum, a motor that rotationally drives the drum, and the outer tank a front side vibration isolating member that supports the lower side of the lower front side and a rear side vibration isolating member that supports the lower rear side of the outer tank, the front side vibration isolating member and the rear side vibration isolating member are at least included The center of gravity of the groove and the drum and the motor without load is disposed further forward.

According to the present invention, the two vibration isolating members which are disposed at intervals in the front and rear can be disposed at a position closer to the center of gravity of the vibration system at the time of the maximum load. Therefore, even in the case of a large capacity drum, it is not necessary. By increasing the number of anti-vibration members, the stability of the vibration system to the load can be improved.

The outer groove 23 is formed into an approximate cylinder having a front surface and a rear surface, and is divided into a groove cover 23b having an opening 23a and a water tank 23c having a back surface. The outer groove 23 has a front opening portion 23a which is connected to the insertion opening 1a of the casing 1 by an annular gasket, that is, a bellows 26, and is sealed by a water seal by closing the door 2.

The vibration detecting means 30 is provided behind the dividing surface 23d, that is, in the water tank 23c, and the groove cover 23b can be removed without changing the connection with the control device 4. Further, the vibration detecting means 30 may be disposed in the upper portion of the outer tank 23 of the approach control device 4, and may be disposed in the tank cover 23b close to the operation panel 3.

In the lower side of the outer tank 23, the drain hose 13 having the drain valve 13b in the path is connected to the drain port 13a. Further, on the left side seen from the front surface of the outer tub 23, a water supply hose 10 having a water supply valve 10b and a lotion container 12 in the path is connected, and by opening the water supply valve 10b, the water supply port 10a is directed to the outer tank. Supply water within 23. Further, the amount of water in the outer tank 23 can be detected by the water level detecting means 14.

On the upper side of the outer tub 23, a counterweight 29 for the purpose of reducing vibration is provided. The weight 29 is provided above the front side vibration-proof member 24, or Further, it is fixed to the slot cover 23b. Further, the weight 29 is not necessarily one, and may be provided even if it is divided into the upper side and the lower side of the rotation axis Z. Further, in order to easily remove the groove cover 23b by weight reduction, the weight 29 may be provided in the water tank 23c.

On the upper side of the outer tub 23, a front suspension spring 27 for holding the posture of the outer tub 23 and a rear suspension spring 28 are provided. The front suspension spring 27 has one end connected to the outer groove 23 and the other end connected to the frame 1, and the outer groove 23 is suspended obliquely upward. The rear suspension spring 28 has one end connected to the outer groove 23 and the other end connected to the frame 1, and the front suspension spring 27 suspends the outer groove 23 in the front-rear direction in the opposite direction. Further, the front suspension spring 27 and the rear suspension spring 28 do not need to be directly connected to the outer tub 23 or the casing 1, and may be connected to a member to which a lubricant or the like is applied in order to improve durability.

In the lower portion of the outer tub 23, in order to prevent the front end or the rear end of the outer tub 23 from being inclined downward, in the connection portion with the outer tub 23, the front side anti-vibration member 24 and the rear side anti-vibration member 25 are separated from the side. Set at regular intervals. The front side vibration-proof member 24 includes a damper 24a for generating a damping force, a compression coil 24b for generating a spring force, and a rubber sleeve 24c (also provided at the upper end of the damper 24a) that is rotatably deformed, and The upper dam base 24d fixed to the outer tub 23 and the lower dam base 24e fixed to the housing 1. Since the configuration of the rear side vibration-proof member 25 is also the same, the description is omitted. The front side anti-vibration member 24 and the rear side anti-vibration member 25 are in the left-right direction, and the upper end is narrower than the lower end, and is viewed from the front. Word configuration. Further, the damper 24a is, for example, an oil damper that uses viscous resistance of the inner seal liquid, a friction damper that uses friction of the sliding portion, an active damper that includes the actuator, and the like. Further, the damper 24a may not be connected to the upper damper base 24d (lower damper base 24e) through the rubber bushing 24c as in the present embodiment, but may be directly connected to the outer groove 23.

In the third embodiment, for the description of the front side vibration isolating member 24 and the rear side vibration isolating member 25, a system including at least the outer groove 23, the drum 21, the motor 22, and the weight 29 (hereinafter referred to as a vibration system) is schematically shown. ), and other major elements. The vibration system is an element that vibrates integrally with the outer tub 23, and also includes a load amount of laundry, water, or the like held in the outer tub 23. G0 in Fig. 3 shows the position of the center of gravity of the vibration system when no load is applied, and G1 is the position of the center of gravity of the vibration system when the maximum load is displayed.

The unloaded state is a state in which the amount of load held in the outer tank 23 such as laundry or water is completely absent, and the water in the outer tank 23 is not completely entered. That is, when no load is applied, the load composed of the product of mass and gravity of the vibration system is the minimum condition. Further, since the center of gravity G0 at the time of no load is relatively large, the motor 22 is located rearward of the center of the drum 21 in the direction of the rotation axis Z.

On the other hand, the maximum load means that the maximum mass (hereinafter referred to as the rated load) of the laundry that can be stored in the drum 21 in the dry state is put into the drum 21, and further, a washing stroke or a washing stroke to be described later. The water retained in the outer tank 23 is in a state of maximum water level. That is, the maximum load is a condition in which the load composed of the product of mass and gravity of the vibration system is the largest. The center of gravity of the vibration system is from no load G0 increases the load and moves forward, and G1 is at the forefront at the maximum load. This is because the center of gravity of the load itself is located at substantially the center of the drum 21 on the rotating shaft Z, and the influence is greater than the mass of the motor 22 with an increase in the amount of load. The center of gravity movement accompanying such an increase in the amount of load is remarkable because the rotation axis Z of the drum 21 is closer to the horizontal level, and the load is more likely to move forward.

For example, the rated load is 10 kg, because the laundry contains 30 to 50 kg of water, which is increased to 3 to 5 times, and water is trapped in the outer tank 23 at 20 to 40 kg when full, so the front side is anti-vibration. The member 24 and the rear side vibration-proof member 25 are mass-supported by a vibration system of about 90 kg.

Here, the front side anti-vibration member 24 and the rear side anti-vibration member 25 are disposed forward of the center of gravity G0 of the vibration system when no load is applied. In other words, the center of gravity G0 of the vibration system at the time of no load, the center line L2 of the rear side vibration-proof member 25, and the center line L1 of the front side vibration-proof member 24 are sequentially arranged from the rear. Therefore, the center of gravity G0 of the vibration system at the time of the lightest no-load is mainly supported by the rear side vibration-proof member 25, and conversely, the load-load G1 of the vibration system at the time of the heaviest maximum load is from the front-side vibration-proof member 24 and Since the two sides of the rear side vibration-proof member 25 are supported, even when the amount of movement of the center of gravity of the vibration system is large, the outer groove 23 can be stably supported.

The front side vibration-proof member 24 is preferably the center of gravity G1 of the vibration system disposed at the maximum load, or more preferably. Thereby, the center of gravity G1 of the vibration system at the time of the maximum load is located between the front side vibration isolating member 24 and the rear side vibration isolating member 25. Front side anti-vibration member 24 and front side anti-vibration member 25 The center L3 in the rear direction is closer to the center of gravity G0 of the vibration system at the time of no load, and is closer to the center of gravity G1 of the vibration system at the time of the maximum load. Therefore, the stability of the vibration system at the time of maximum load can be further improved. Further, in this configuration, the distance between the center of gravity G0 of the vibration system and the front side vibration-proof member 24 at the time of no load is long, but the force for inclining the outer groove 23 is small at the time of no load, so the influence is small.

Here, FIG. 4 is a view showing the use of the front side vibration isolating member 24, the rear side vibration isolating member 25, and the drum 21, the center of gravity of the vibration system accompanying the load amount, and the magnitude of the load applied to the center of gravity of the vibration system. At the approximate center of the front-rear direction of the drum 21, the same load P generated by the amount of load is applied, and the load F2 is generated vertically downward. On the other hand, in the center of gravity G0 of the vibration system at the time of no load, the load F0 is applied vertically downward. When the load is increased and the load P is increased, the center of gravity of the vibration system is the center of gravity G1 of the vibration system near the maximum load, and the magnitude of the load is also close to the maximum F1. Further, by the maximum load F1, the amount of contraction of the front side anti-vibration member 24 or the rear side anti-vibration member 25 is maximized. At this time, the closer the distance between the front side anti-vibration member 24 and the rear side anti-vibration member 25 is, the smaller the difference in the amount of shortening is, and the inclination of the outer groove 23 becomes small. On the other hand, when the amount of load is small, the distance between the front side anti-vibration member 24 and the rear side anti-vibration member 25 is long, and since the mass of the support is small, the difference in the amount of shortening is small. Therefore, in the present embodiment, by supporting the front side vibration-damping member 24 and the rear side vibration-proof member 25 in the vicinity of the center of gravity G1 of the vibration system at the time of maximum load, it is possible to improve the stability of the vibration system for increasing or decreasing the amount of load. Sex.

And the front side anti-vibration member 24 is disposed on the split surface Further behind 23d, the sink 23c. Thereby, since the water tank 23c has the strength of the bottomed cylindrical type compared with the groove cover 23b which has the opening part 23a, the center of gravity G1 of the vibration system at the time of the maximum load can be stably supported.

On the other hand, the rear side vibration-proof member 25 is provided on the side where the dehydration rotation direction of the drum 21 is downward as indicated by an arrow A (refer to FIG. 2). Therefore, in the outer groove 23, the right oblique direction is the vibration state of the elliptical orbit of the long diameter (refer to the arrow B in FIG. 2), and the amount of expansion and contraction and the expansion and contraction speed of the rear vibration-damping member 25 are changed. The vibration is effectively attenuated toward the outer groove 23 with low attenuation. Such a vibration state is easy when the mode in which the outer groove 23 vibrates in the left-right direction and the number of resonance rotations in the mode in which the vertical direction vibrates is close, and in particular, a small amount of clothes such as a single bath mat tends to become large. In other words, the vicinity of the center of gravity G0 of the vibration system at the time of no load is an elliptical orbit indicated by an arrow B in the second figure by vibrating from the right direction and the upper direction to the left direction and the lower direction. Therefore, by providing the rear side vibration-proof member 25 in the vicinity of the center of gravity G0 of the vibration system at the time of no load, the vibration reduction can be efficiently achieved. In the case where the spin-drying direction of the drum 21 is rotated to the left, the rear side vibration-damping member 25 is turned to the left side from the front, and the rear-side vibration-damping member 25 is the right side.

The front side anti-vibration member 24 and the rear side anti-vibration member 25 are disposed in front of the connection portion between the front suspension spring 27 and the outer groove 23 and the connection portion between the rear suspension spring 28 and the outer groove 23. Therefore, when the center of gravity G1 of the vibration system at the time of the maximum load is located further forward than the front side vibration-proof member 24, since the front end or the rear end of the outer groove 23 is pulled upward, Therefore, the stability of the vibration system can be improved. Moreover, in order to further improve the stability of the vibration system at the time of the maximum load, the front side anti-vibration member 24 and the rear side anti-vibration member 25 are disposed behind the connection portion of the rear suspension spring 28 and the outer groove 23, and are suspended from the front side. Both the suspension spring 27 and the rear suspension spring 28 preferably pull the front end of the outer groove 23 upward. This is a suspension of the upper portion of the outer groove 23 so as to form a "V" from the side of the front side anti-vibration member 24.

The operation of the above configuration will be described. When the door 2 is opened and the laundry is put into the drum 21, and a predetermined amount of the lotion is put into the lotion container 12, and the operation is started, the washing process is first performed. During the cleaning process, the water supplied to the water supply valve 10b is supplied through the lotion container 12 and the water supply hose 10, and enters the outer tank 23 together with the lotion. After the operation is performed for a predetermined period of time, the drum 21 is subjected to a stirring operation of reverse rotation, stop, reverse rotation, and stop for a predetermined period of time. At this time, the laundry accommodated in the drum 21 is lifted in the rotation direction by the elevator 21b provided on the inner peripheral wall of the drum 21, and is knocked up by the stirring operation from the height position that has been lifted. The washing action is carried out by washing in the laundry.

After this action is performed for a predetermined period of time, the cleaning process is terminated and the dehydration process is carried out. In this dehydration process, the drain valve 13b is first opened, and the water in the outer tank 23 is drained to the outside through the drain hose 13. Next, the drum 21 is rotated in the spin-drying direction of the arrow A (rotation in the left direction in the present embodiment), and after being rotated to a predetermined time after reaching a predetermined rotation speed (for example, 900 r/min), the water contained in the laundry is dehydrated. .

After the dehydration process is performed for a predetermined period of time, the water supply valve 10b The feed water is turned on, and the water passes through the lotion container 12 and the water supply hose 10, and water is injected into the outer tank 23 to perform a washing process. In the cleaning process, the stirring operation of the reverse rotation, the stop, the reverse, and the stop operation is performed for a predetermined period of time in the same manner as the above-described cleaning process. At this time, the laundry is lifted in the rotation direction by the elevator 21b provided on the inner peripheral wall of the drum 21, and is washed by the height position which has been lifted up, so it is included in the washing of the laundry. The ingredients are washed cleanly. Further, in the case of a drum-type washer-dryer having a drying function, the drying process is performed thereafter.

As described above, in the present embodiment, the front side anti-vibration member 24 and the rear side anti-vibration member 25 are disposed in front of the center of gravity G0 of the vibration system at the time of the lightest no-load, because the vibration system at the maximum load can be used. Since the distance between the center of gravity G1 and the front side vibration isolating member 24 and the rear side vibration isolating member 25 is close to each other, when the center of gravity of the vibration system with the load amount is large, the number of the vibration isolating members does not need to be increased. The inclination of the outer groove 23 can be prevented, and the stability of the vibration system for the load can be improved.

Further, in the present embodiment, the drum type washing machine has been described, and the same effect can be obtained by the drum type washing and drying machine having the drying function. Further, in the present embodiment, the dehydration rotation direction is set to the left rotation, but the opposite right rotation may be used. In this case, the front side anti-vibration member 24 is provided on the left side from the front side, and the rear side anti-vibration member is provided. 25 The same effect can be obtained by setting it on the right side from the front.

<Example 2>

Fig. 5 is a view showing the internal structure of the back surface of the drum type washing machine in the second embodiment. A motor 50 is provided in the lower rear side of the outer tank 23. A front side vibration-proof member 54 is provided in front of the motor 50, that is, in the right side of the outer tank 23, and a rear side vibration-proof member 55 is provided in the left side of the outer tank 23. Further, the pulley 51 provided on the back surface of the outer tub 23 is coupled to the back surface of the drum 21, and rotatably supports the drum 21. The power of the motor 50 is transmitted to the pulley 51 through the belt 52, so that the drum 21 can be rotationally driven in the left-right direction. In the present embodiment, the dehydration rotation direction is the left rotation.

According to the above configuration, since the rear side of the front side anti-vibration member 54 is wider than the rear side anti-vibration member 55, the space for arranging the motor 50 can be secured. In other words, since the motor 50 can be enlarged, it is possible to emit a large output while suppressing an increase in the number of rotations, and it is possible to suppress noise caused by the number of rotations.

In the present embodiment, the front side vibration isolating member 54 and the motor 50 are disposed on the right side as viewed from the front, but when the dehydration rotation direction is the right rotation, the front side vibration isolating member 54 and the motor 50 are disposed from the front side. On the left side, the same effect can be obtained.

<Example 3>

Fig. 6 is a view showing the internal structure of the upper surface of the drum type washing machine in the third embodiment. Fig. 6 is a view showing the intermediate line X of the front side anti-vibration member 24 and the rear side anti-vibration member 25, and the rotation axis Z of the drum 21 perpendicularly intersecting therewith, and the outer groove 23 is divided into A1, A2, and A3 from the upper side. And 4 areas of A4. Front suspension spring provided at the front end of the outer groove 23 60, the rotation axis Z of the drum 21 is disposed in the vicinity of the rear side vibration-proof member 25, and the rear suspension spring 61 provided at the rear end of the outer groove 23 is disposed near the front side vibration-proof member 24 with respect to the rotation axis Z of the drum 21. . That is, the rear side vibration isolating member 25 is disposed in the area A1, the front suspension spring 60 is disposed in the area A2, the front side vibration isolating member 24 is disposed in the area A3, and the rear suspension spring 61 is disposed in the area A4. The other configurations and operation controls are the same as in the first embodiment, and the same reference numerals are attached thereto, and the description thereof is omitted.

According to the above configuration, since the front suspension spring 60 and the rear suspension spring 61 are suspended upward by the region A2 or A4 that does not support the outer groove 23 from below, the region A2 or the region A4 of the outer groove 23 can be prevented. Tilt down. Further, since the front suspension spring 60 and the rear suspension spring 61 are disposed above the rotation axis Z of the drum 21 having the narrowest space in the space above the outer groove 23, the space above the outer groove 23 is widened. The collision of the outer groove 23 and the frame 1 is prevented.

Moreover, when the dehydration rotation direction of the drum 21 is reversed, the same effect can be obtained by making bilateral symmetry.
