Abstract

PROBLEM TO BE SOLVED: To prevent the transmission of vibration to an installing floor and to prevent the amplitude of a main body at the time of starting dehydrating or the time of normal dehydrating by providing an installing part to a floor face in a drum type washing machine with a non-repulsive rubber is the state of a thin plate so as to be resistant to the weight of a main body. SOLUTION: The material of an installing leg 19 to be fixed to the bottom part of the main body as an installing part is non-repulsive rubber of a proper thickness. At the time of increasing the rotating speed of a drum from zero, it passes through the resonance frequency of a system consisting of the installing face 29 and the washing machine main body 1. At the time, the main body is in particular oscillated large. In addition, the large oscillation of the main body is apt to be generated as well at the time of slowly dehydrating rotation because of being close to the resonance frequency then. At the time, the corner part of the bottom of the main body is apt to sink downward. In order to prevent it, the installing leg 19 is arranged at the part to suppress the sinking downward of the corner by the deformed quantity of the rubber itself due to a downward load added to the corner to suppress the horizontal oscillation of the main body 1.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drum type washing machine (including a drum type washing machine for performing drying up to drying) which reduces the amplitude of the main body during the dewatering step and the transmission of vibration to the floor.

[0002]

2. Description of the Related Art Conventionally, a large number of horizontal drum-type washing machines rotating about a horizontal axis have been proposed, and most of the washing machines used in Europe are of this type. . In general, a washing machine of this type performs a washing operation by continuously rotating a rotating drum at a low speed. By using this rotating drum, dehydration and drying can be easily performed. The conventional drum-type washing machine and the drum-type drying and washing machine of the present invention have substantially the same basic configuration. Therefore, common contents are shown in FIGS. The outline of the structure and operation will be described with reference to the drawings.

[0003] This drum-type drying and washing machine includes a washing machine main body 1.
Inside the spring, there is a spring 2 to absorb the vibration during driving.
7 and a water tank 4 suspended by a shock absorber 28
And a drum 2 arranged to rotate around a horizontal axis inside the water tank 4. 2 of FIG.
Reference numeral 0 denotes an operation / display portion, and the control device 21
Is attached. The water tank 4 has a function of storing and discharging the washing liquid and the dehydrating liquid. The drum 2 is provided with a number of small holes all over its peripheral wall to supply water for washing, drainage for dehydration, and hot air for drying. A drying unit 13 is attached to the upper part of the water tank 4. In addition, a circulation duct 7 for circulating hot air during drying is provided. A door 23 for loading and unloading laundry is provided on the front of the main body.
Reference numeral 3 denotes a structure that is closed by a door packing 25 between the water tank 4. Reference numeral 16 denotes a drive motor for rotating the drum 2, and reference numeral 11 denotes a drainage pump for discharging washing liquid and the like outside the machine. Reference numeral 26 denotes a lint filter provided in a piping path between the water tank 4 and the drainage pump 11.

[0004] A conventional installation portion of the main body 1 is shown in FIG.
As shown in FIG. 5, there is a bolt-shaped adjusting leg 19 screwed into the bottom of the main body, and includes a support rod 193 and a grounding portion 194 having one end fixed to the bottom of the main body.

[0005]

However, in such a conventional drum type washing machine, when the main body of the washing machine is placed on a wooden floor of a general household or on a waterproof pan, and the drum is rotated at a high speed, the cloth is washed. If the imbalance occurs in the drum, the vibration of the main body will be transmitted to the installation floor via the installation legs, and will cause the installation surface to vibrate significantly at the natural frequency of the wooden floor and waterproof pan, especially noise and house vibration. Was what caused it.

In view of this, an elastic body such as rubber is provided on the installation portion between the installation leg and the floor surface, and the resonance frequency of the system including the installation surface and the washing machine is set to be lower than the frequency of the fundamental vibration in the steady state of dehydration. The purpose is to reduce the vibration of the washing machine during dehydration.

Therefore, making the elastic body of the installation leg sufficiently flexible lowers the resonance frequency of the system consisting of the installation surface and the washing machine, and reduces the vibration of the main body during high-speed rotation during spin-drying. Becomes However, on the other hand, a large body amplitude is caused at the time of dehydration rising or at the time of low-speed spinning.

Conversely, if the elastic body of the installation leg is made slightly hard,
Although the large body amplitude can be suppressed at the time of spin-drying or low-speed spinning, the resonance frequency increases, and the body amplitude is not sufficiently reduced even at high-speed spinning. In particular, in the case of a drum-type drying washing machine, the weight of the main body is large, and a slightly harder elastic body has a reduced vibration absorbing effect, and a large force for transmitting vibration to the floor.

As described above, since the transmission of vibration to the floor and the amplitude of the main body are in an opposite relationship, it is difficult to suppress both of them with the above configuration.

An object of the present invention is to solve the problems of the above-mentioned conventional structure, and to withstand the weight of the main body.
It is a first object of the present invention to provide a drum type washing machine that prevents vibration from being transmitted to an installation floor and prevents the amplitude of the main body at the start of dehydration and during dehydration.

[0011] Also, when installing on a mounting surface that is likely to cause large vibration and body amplitude, such as a wooden floor, especially a Japanese house or a waterproof pan, or when the vibration amplitude is large after installation, the installation legs can be easily mounted. It is a second object of the present invention to prevent vibrations from being transmitted to the installation floor and to prevent the amplitude of the main body at the start of dehydration or during dehydration.

In addition, vibrations are prevented from being transmitted to the installation floor, and the amplitude of the main body at the start of dehydration or at the time of dehydration steady is prevented by using the installation legs having a shape improved in mounting. As a third object.

[0013] Further, it can be easily and accurately attached, eliminates the displacement between the installation leg and the main body, prevents vibration from being transmitted to the installation floor, and sets the amplitude of the main body at the start of dehydration or at the time of steady dehydration. The fourth object is to prevent the above.

[0014]

SUMMARY OF THE INVENTION The present invention is directed to a washing machine provided with a rotating drum which freely rotates about a horizontal axis in a water tank arranged in an outer box and stores laundry therein. In a drum type washing machine that performs a series of washing operations such as rinsing and dehydration in one drum, a non-repulsive thin plate-shaped rubber is provided in an installation portion with respect to a floor surface.

The non-repulsive thin plate-like rubber is provided at a corner of the bottom of the main body and has a thin plate shape having a large contact area with the floor surface or a rib rising up along the outer periphery at the corner of the bottom of the main body. It is the formed shape.

In the present invention, a non-rebound rubber having a rebound resilience coefficient of 10 or less and a thickness of 15 mm to 20 mm is used.

According to the present invention, the applied load is applied via the non-repulsive rubber, and the vibration of the main body during the start of dehydration or at the time of low-speed dehydration is damped by the deflection in the thickness direction of the rubber material.
Further, by providing a non-repulsive rubber at the corner of the bottom of the main body, the vertical movement of the corner of the bottom of the main body is limited to only the deflection in the thickness direction of the rubber. In addition, the transmission of vibration to the floor is sufficiently absorbed and damped by making the relatively flexible rubber material widely contact the installation surface. Therefore, the amplitude of the main body and the transmission of vibration to the floor can be prevented with a weak wooden floor or a waterproof pan.

Further, it is easy to install even if it is retrofitted according to the installation condition by a thin non-resilient rubber which can be fitted or closely attached to the installation leg supporting the main body, which is arranged on the bottom of the main body. It is possible to prevent the amplitude of the main body and the transmission of vibration to the floor with a weak wooden floor or a waterproof pan.

Further, by providing ribs which are in close contact with the bottom corners of the main body, the accuracy at the time of mounting is improved, and the bottom corners of the main body are reliably prevented from sinking, so that the wooden floor or waterproof pan can be used. Vibration of the main body can be prevented, vibration can be absorbed by a large installation area, and transmission of vibration to the floor can be prevented.

According to the present invention, the installation legs for supporting the main body are
By adopting a thin plate of non-resilient rubber and fitting the unevenness provided on the bottom of the main body and the rubber respectively, it is possible to accurately and easily mount at the time of installation, while eliminating the displacement between the installation leg and the main body The main body amplitude can be prevented by a weak wooden floor or a waterproof pan, and the vibration can be absorbed by the large installation area, and the transmission of the vibration to the floor can be prevented.

The installation leg as the installation portion of the present invention is 19 in FIGS. 1 and 2 and is attached to the bottom of the main body. FIG.
Is a longitudinal sectional view showing the installation legs. This prevents the amplitude of the main body 1 from increasing and the vibration of the main body 1 from being transmitted to the installation floor. As shown in the drawing, the installation legs 19 are arranged so that one side surface substantially matches the side surface of the bottom of the main body. The sides may be slightly outside or slightly inside. This installation leg 19 has a rectangular parallelepiped shape and a length of 100 mm,
It has a width of 50 mm and a thickness of 15 mm, and is provided at four corners of the main body.

The mounting leg 19 is made of non-resilient rubber (having a rebound resilience coefficient of 10 or less) and has a suitable thickness (for example, 15 mm to 20 mm). Also,
By attaching a non-slip such as a double-sided tape to one surface of the installation leg 19, it is possible to prevent a deviation from the main body 1. Then, the washing machine main body 1 is slightly inclined at the time of installation by peeling off the release paper of the double-sided tape, and the installation legs 19 are attached to the corners at the bottom of the main body, so that the installation can be performed.

Further, as shown in FIG. 5, a screw hole is provided in the bottom of the main body, and a counterbore is provided in a non-repulsive rubber plate, so that fixing by screw 39 is also possible.

In any case, the above-mentioned object is achieved by arranging the installation legs 19 so as to be located at the corners of the bottom of the main body with a large contact area between the bottom of the main body and the installation surface side 29.

The operation of this embodiment will be described below. First, the general operation of the operation from the washing process to the dehydration process will be described. In the washing process, the laundry is put in the drum 2, the detergent is put in the detergent case 22, and the power is turned on.
When the start key on the panel input section 20a is pressed, the washing operation is started.

First, after the door 23 is locked, the water supply valve 6 is opened to supply water, the washing liquid in which the detergent is dissolved is poured from above into the laundry, and the drum 2 is rotated at a low speed. Done. The laundry in the drum 2 is lifted to near the top of the drum 2 by centrifugal force due to the rotation of the drum 2 and the baffle 3, and then falls by its own weight (referred to as tumbling). By repeating this tumbling, the laundry is beat-washed with the impact force at the time of falling. Rinsing is performed similarly. After washing,
The rotation of the drum 2 is stopped, and the drain pump 11 is turned on to discharge the washing liquid out of the machine.

After the washing and rinsing steps are completed, and after the drainage is completed (after the reset water level is detected), the process proceeds to the dehydration step, and the unbalance correction step of the low-speed reversal operation for correcting the unbalance of the clothes is performed. After the unbalance correction step is completed, a low-speed rotation (about 85 rpm) unbalance detection step is performed for the purpose of detecting the unbalance of the clothes. When the unbalance detection step detects an unbalance detection level or less, first, the speed is changed to a low-speed spinning speed, for example, 450 rpm, and the laundry is centrifugally generated by the rotation of the drum at that time to wash the laundry on the inner surface of the peripheral wall of the drum 2. It is done in such a form as to press against. After that, high-speed dehydration rotation, for example, 1000 r
pm, and the operation is terminated after a predetermined time has elapsed.

In this dewatering step, a certain amount of laundry imbalance may occur in spite of the imbalance correction and the imbalance detection. The water tank 4 vibrates due to the imbalance. This vibration is transmitted to the main body 1 via the spring 27 and the shock absorber 28, and the main body 1 vibrates under this influence.

As the rotation speed of the drum increases from 0, the drum passes the resonance frequency of the system consisting of the installation surface 29 and the washing machine main body 1. At that time, the main body particularly vibrates greatly. Further, since the resonance frequency is close to the resonance frequency even at the time of low-speed spinning, a large body amplitude tends to occur. At this time, as shown in FIG. 4, the corner of the bottom of the main body is about to sink downward. In order to prevent this, the installation feet 19 are arranged in that part, and the sinking under the corner is suppressed only by the amount of deflection of the rubber itself due to the downward load applied to the corner, so that the side of the body 1 can be prevented. Hold the shaking.

FIG. 6 is a graph showing the amplitude of the main body in the horizontal direction measured at the upper portion of the side of the main body during the dehydration operation according to the conventional example and the present embodiment. The horizontal axis indicates time (minutes), and the vertical axis indicates amplitude value (mm). From this graph, it can be seen that in the process of sequentially increasing the rotation speed of the drum, the increase in the vibration caused by resonance is suppressed, and the amplitude value is significantly reduced according to the present embodiment as compared with the conventional example. .

Further, since the contact area with the installation surface 29 is large, the pressure applied to the installation surface 29 is reduced, and the force applied to the floor surface is absorbed by a wide range of rubber buckling in the thickness direction. Therefore, according to this embodiment, the amplitude of the main body 1 at the resonance frequency and the amplitude of the main body at the time of low-speed dehydration, which are passed when the rotation speed of the drum 2 rises, are suppressed, and the vibration of the main body 1 is suppressed. Is not greatly transmitted to the installation floor 29.

Next, another embodiment of the present invention will be described with reference to FIG. The installation leg 19 is made of a non-resilient rubber 19 as compared with the conventional one arranged at the corner of the bottom of the main body.
a is externally fitted. The rubber 19a for external fitting can be retrofitted, and after being installed on a wooden floor or a waterproof pan, when the vibration is large, the main body 1 can be easily tilted and fitted.

FIG. 8 is a perspective view of the external fitting rubber 19a according to the second embodiment. As in the first embodiment, the material is a non-repulsive rubber, and a through hole 196 is provided. The through-hole naturally corresponds to the shape (round, hexagon, etc.) of the installation leg 19. The size is set to the same size as the installation leg 19 attached to the bottom of the product main body. In addition, by setting the size of the through hole 196 to a size slightly larger than the size of the installation leg 19 to be fitted, it is possible to prevent the through-hole 196 from slipping when fitted. The thickness of the installation leg 19 is set to be larger than the thickness of the installation leg 19 originally attached to the main body 1.

Further, as another embodiment, as shown in FIG. 9, a shape adapted to the outer shape of the installation leg attached to the bottom of the product may be closely attached to the bottom surface of the installation leg. This corresponds to the case where the installation feet 19 attached to the bottom of the product body are round or hexagonal. In this case, similarly to the first embodiment, by assuming the time of attachment, by attaching a double-sided tape to one surface (the surface in contact with the main body),
It can be easily retrofitted.

These are characterized in that they can be easily attached even in a narrow space once the main body 1 is installed, without the trouble of removing the installation legs 19 attached to the product.

Hereinafter, the operation of the present embodiment will be described. When the rotation speed of the dehydration increases in a state where the drum 2 has an imbalance, the water tank 4 vibrates, and when the resonance frequency is passed, or when the rotation speed is close to the resonance frequency, the rotation speed is low. In particular, the main body 1 swings greatly.

At this time, the corner at the bottom of the main body tries to sink downward. In order to prevent this, the installation feet 19 are arranged in that part, and the sinking under the corner is suppressed only by the amount of deflection of the rubber itself due to the downward load applied to the corner, so that the side of the main body 1 can be prevented. Keep shaking. Further, since the contact area with the installation surface 29 is large, the transmission force to the floor is dispersed and reduced as in the above-described embodiment.

Further, regarding the third embodiment of the present invention,
A description will be given based on FIG. The installation leg is a thin plate, made of non-resilient rubber, and has a rib 191 provided on an end face. The rib 191 is provided so as to be in close contact with the bottom corner of the main body, can be reliably positioned at the time of attachment, and can reliably contact the corner of the bottom of the main body which is a condition for achieving low vibration. . FIG.
2 shows a perspective view of the installation leg according to this embodiment.

In this case as well, the operation is the same as in the first and second embodiments, and it is possible to reduce the vibration amplitude of the main body 1 and the vibration transmitting force to the floor.

Further, regarding the fourth embodiment of the present invention,
This will be described with reference to FIG. As shown in the figure, the mounting legs are made of a thin plate and made of non-resilient rubber.
92, or a concave portion is provided on the surface in contact with the main body. Also in this case, the installation feet 19 are arranged at the corners at the bottom of the main body. A concave portion (hole) or a convex portion is provided at the bottom of the main body. The concave-convex portion is arranged at a position where the concave-convex portion is inevitably disposed at the corner at the bottom of the main body when fitted.

As a result, the mounting legs can be accurately positioned, that is, the installation legs can be reliably positioned at the corners of the bottom of the main body, and can be easily mounted. Then, the displacement from the main body 1 can be reliably prevented.

In this case as well, the operation is the same as in the first and second embodiments, and it is possible to reduce the vibration amplitude of the main body 1 and the vibration transmitting force to the floor.

The present invention makes use of the non-repulsive rubber, in particular, when a drum-type drying and washing machine is installed on a wooden floor such as a Japanese house, vibration generated by rotation of the drum resonates with the Japanese house. This is different from the one provided simply with a vibration absorbing material.

[0064]

According to the present invention, it is possible to reduce the generation of vibration and noise when using the drum type washing machine. Further, since the configuration and operation are performed as described above, the following effects can be obtained.

The installation legs for supporting the main body are made of thin, non-resilient rubber having a large contact area with the floor and provided at a corner portion of the bottom of the main body, so that they can withstand the load of the main body and start dehydration. In addition, it is possible to prevent vibrations during the steady state of dehydration from being transmitted to the installation floor, and to prevent amplitude of the main body.

The installation legs for supporting the main body are fitted or closely attached to the installation legs originally attached to the bottom of the main body, and are also provided on a wooden floor, a waterproof pan, or the like, which is likely to cause a large vibration amplitude. For installation or when the vibration amplitude is large after installation, the positioning of the installation is easy, and the installation displacement can be easily confirmed, and the displacement can be prevented.
Prevents vibration during dehydration steady state from being transmitted to the installation floor,
Further, it is possible to provide a drum type washing machine capable of preventing the amplitude of the main body.

The mounting legs for supporting the main body are provided at the corners of the bottom of the main body with a convex or concave portion formed of a thin, non-resilient rubber having a large contact area with the floor surface, and a bottom of the main body. By providing recesses (holes) or protrusions and fitting the respective protrusions and recesses, it can be mounted accurately and easily, eliminating the displacement of the installation leg and the main body, at the start of dehydration, or at the time of dehydration steady Can be prevented from being transmitted to the installation floor, and the amplitude of the main body can be prevented.
