る。[Prior Art] A conventional drum-type washing machine is shown in FIGS. 7 and 8.
The configuration was as shown in . That is, inside the washing machine main body 51, there is provided a water tank 53 which is supported by a suspension 52 at the top, and inside the water tank 53, the front side is open and a rotating shaft 54 is provided at the rear surface, and a plurality of water passage holes 55 and the rotating shaft 54 are provided on the side surface.

に設置するには、床を強固に補強する必要があった。[Problems to be Solved by the Invention] In the configuration of such a conventional drum-type washing machine, when dehydration is to be performed after washing and rinsing, the drum is rotated at high speed with the clothes being biased toward the lower part of the drum 57. let At this time, the drum 57 vibrates greatly due to the eccentric load caused by the clothing. In order to suppress this vibration, the damper 64 needed to have a very strong capacity, and a weight body 65 had to be attached to the water tank 53. This made the unit quite heavy, making it impossible to carry it by one person, and in order to install it on the wooden floor of a typical Japanese home, the floor needed to be strongly reinforced.

軸方向に長く設定するには制限がある。[0004] Therefore, in order to suppress the vibration of the drum 57,
It is easy to think that the fluid balancer used in fully automatic washing machines, which is currently popular in Japan and has a rotating shaft on the bottom, can also be used in this drum-type washing machine. However, unlike a fully automatic washing machine, a drum-type washing machine has a rotating shaft 54 on the side, and the fluid balancer enters the wash water during rinsing, reducing the volume of the washing section. Therefore, there is a limit to making the fluid balancer longer in the direction of the rotation axis in order to improve the correction force during dehydration.
【０００５】さらに、脱水起動時に、ドラム５７は共振
周波数近傍にて大きく振れ回るといった問題もあった。[0005]Furthermore, there is another problem in that the drum 57 swings around a lot in the vicinity of the resonance frequency when dewatering is started.

The first objective is to reduce dehydration vibration during the dewatering process, and at the same time to minimize the decrease in drum volume during the washing process to maintain cleaning performance.

A water tank provided, a drum having a rotating shaft on the side and rotating around this rotating shaft, a pulley attached to the rotating shaft and disposed outside the water tank, and a drum via the pulley and belt. The drum is equipped with a driving motor, and a plurality of fluid balancers separated in the radial direction are provided on the periphery of the end of the drum in the direction of the central axis.

抑えられる。[Function] With the above-described structure of the drum-type washing machine of the present invention, the drum vibrates due to the eccentric load caused by the clothes, but when the resonance frequency of the vibration system is exceeded, the fluid inside the radially separated fluid balancer generally It has a tendency to gather in the opposite direction to the eccentric load, so you try to balance the drum yourself. That is, the fluid in each fluid balancer gathers at a position 180 degrees out of phase with the centrifugal force caused by the clothing, and a corrective centrifugal force acts to offset the centrifugal force caused by the clothing. As a result, large dewatering vibrations can be suppressed without occupying a large internal volume of the drum.

りを抑えることができる。[0011]Furthermore, when the drum stops after the washing and rinsing processes and moves on to the dewatering process after draining, the fluid in each fluid balancer separated in the radial direction accumulates at the bottom due to gravity when the draining is completed. ing. When the drum is rotated in this state, the fluid in each fluid balancer rotates while being biased at the same location in the circumferential direction of each fluid balancer due to centrifugal force and gravity during rotation, causing large vibrations. Therefore, by making the fluid flow resistance of each of the multiple fluid balancers different, it is possible to prevent each fluid from remaining biased at the same location in the circumferential direction. It is possible to suppress the whirling of the drum near the resonance frequency.

Thereafter, it falls into the washing water from near the top of the drum 7. Clothes are washed by repeating this operation.

脱水振動が抑えられる。[0016] Next, after the washing and rinsing processes are completed and before the dehydration process begins, the clothes in the drum 7 are biased towards the bottom of the drum 7. When rotating at high speed in this state, the drum 7 vibrates due to the eccentric load caused by the clothing, but once the resonance frequency of the vibration system is exceeded, the fluid inside the fluid balancer generally tends to gather in the opposite direction to the eccentric load. , try to balance drum 7 by yourself. In other words, the fluids in the first fluid balancer 9 and the second fluid balancer 10 gather at a position 180 degrees out of phase with the centrifugal force caused by the clothes, and corrective centrifugal force acts to offset the centrifugal force caused by the clothes, causing the fluid to move in the direction of the rotation axis 4. Approximately twice the corrective centrifugal force can be obtained without increasing the length of the fluid balancer. This suppresses large dehydration vibrations.

水性能も維持することができる。Furthermore, since the first fluid balancer 9 and the second fluid balancer 10 are doubled in the radial direction, the area that occupies the inner surface of the drum 7 is small, so the width of the baffle 6 is made longer during washing and rinsing. Since the volume of washing water can be increased, it is possible to make the clothes work better and maintain washing performance, and the number of water passage holes 5 provided on the side of the drum 7 can be maintained during dewatering. Therefore, dehydration performance can also be maintained.

In addition, the corrective centrifugal force of the fluid balancer can be improved, and dehydration vibration can be further suppressed.

A first fluid balancer 9a on the outside and a second fluid balancer 10a on the inside are provided. Inside the first fluid balancer 9a and the second fluid balancer 10a, a first partition plate 24 and a second partition plate 25 are provided, each having a first communication hole 22 and a second communication hole 23 having different areas in the outer circumferential direction. ing. In this embodiment, the area of the first communication hole 22 is set smaller than the area of the second communication hole 23.

The first fluid 27 and second fluid 28 in the second fluid balancer 10a are collected at the bottom due to gravity. When the drum 7 is rotated in the direction of arrow a in this state, the operation up to the resonance frequency will be described.

よって大きな脱水振動が抑えられる。As shown in FIG. 6, the first fluid balancer 9
Since the area of the first communication hole 22 is small and the flow resistance is large, the first fluid 27 in the chamber a remains fixed in the chamber when the first communication hole 22 is stopped.
It rotates together with the fluid balancer 9a. However, within the second fluid balancer 10a, the area of the second communication hole 23 is large and the flow resistance is small, so the second fluid 28 flows as shown by arrow b and rotates later than the second fluid balancer 10a. As a result, the first fluid 27 and the second fluid 28 inside the first fluid balancer 9a and the second fluid balancer 10a are at different positions in the circumferential direction near the resonance frequency, so that dehydration is caused by eccentricity of the fluid inside the fluid balancer. It is possible to suppress whirling of the drum 7 near the resonance frequency at startup. After that, when the resonance frequency is exceeded, the first fluid 27 and the second fluid 28 in the first fluid balancer 9a and the second fluid balancer 10a pass through the first communication hole 22 and the second communication hole 23, and the eccentric load is increased. They gather in the opposite direction and try to balance drum 7 by themselves. This suppresses large dehydration vibrations.
