Description

The present invention relates to a washing machine having a dehydrating function.

Some washing machines installed in a general household or a coin laundry have a washing/dewatering function and a washing/dewatering/drying function.

In a washing machine having a dehydrating function, vibration and noise are generated due to uneven distribution of laundry in the rotating drum. If the unevenness of the laundry is large, the eccentricity of the rotating drum during rotation becomes large, and a large torque is required for rotation, so that the dehydration operation cannot be started. In order to eliminate this, the user stops the operation of the washing machine and manually eliminates the unevenness of the laundry.

In order to eliminate such troublesome work, when it is determined that the magnitude of the imbalance, which is the unevenness of the laundry, is larger than a predetermined value, the rotation in which the centrifugal force is smaller than the gravity depending on the output timing of the position detection means. It has been proposed to reduce the unevenness of laundry by reducing the speed of the rotating drum until the speed reaches the speed (see Patent Document 1).

In addition, in order to prevent the occurrence of an imbalance in which the laundry is biased toward the front part of the rotating drum during dewatering, the acceleration sensor installed on the front part and the rear part of the rotating drum calculates the difference between the detected vibration amounts. There has been proposed a method in which an unbalanced state in which the laundry is biased to the front part of the rotary drum is detected (Patent Document 2).

JP-A-9-290089 JP, 2009-82558, A

The technique disclosed in the above-mentioned Patent Document 1 gradually reduces the centrifugal force by decelerating the rotation of the rotary drum, and causes the overlapping laundry to drop by gravity. However, in this conventional technique, the laundry that is entangled with each other into a lump will drop as it is, and therefore the lump cannot be unraveled. When the rotating drum is rotated in such a state, the unbalance has not been eliminated, so the unbalance is detected again, and the deceleration of the rotating drum is repeated.

On the other hand, the technique disclosed in Patent Document 2 calculates the difference between the vibration value detected by the front vibration detection means and the vibration value detected by the rear detection means when the rotary drum is rotating. .. Then, when the difference between the vibration values exceeds a preset threshold value, the rotation of the rotary drum is decelerated or stopped.

However, even with this conventional technique, the laundry that is entangled with each other in a lump is still unraveled and remains in the rotating drum, which is not a fundamental solution for eliminating the imbalance.

Further, according to the above-mentioned Patent Documents 1 and 2, since the rotation of the rotary drum is decelerated or stopped, not only the starting power is required every time the dehydration operation is repeated, but the power consumption increases, and the time required for washing, that is, the operation. There is a problem that time is delayed. Particularly in the case of a washing machine installed in a coin laundry, a delay in operating time leads to a reduction in the rotation efficiency of the customer in the store.

It should be noted that these problems can occur not only in a drum type washing machine having a rotating drum (washing tub) but also in a vertical washing machine.

The present invention focuses on the points as described above, and it is possible to avoid decelerating or stopping the rotation of the washing tub even if the laundry is unevenly distributed in the washing tub. To provide a washing machine capable of effectively avoiding a delay in operating time by reliably and promptly eliminating an imbalance.

The present invention takes the following means in view of the above problems.

The washing machine of the present invention includes a washing tub having a drive device on the base end side and an opening on the tip end side, and a plurality of washing tubs arranged on the inner peripheral surface of the washing tub along the axial direction of the washing tub. Is a hollow balancer, and a water injection device for individually injecting adjusted water into each of the balancers, wherein the washing tub extends with its axial direction substantially horizontal or inclined at an angle close to horizontal. The balancer has a drum rotatably supported around the axis, and the balancer suppresses the flow of the adjusted water injected from the tip side of the washing tub to the base end side by the water injection device. By having a partition part capable of retaining the adjusted water on the tip side, and an outlet part capable of discharging the injected adjusted water from the base end side of the washing tub , wherein the partition part is the washing tub. It has an inclined surface inclined so as to gradually approach the rotation center of the drum from the front end side to the base end side .

Further, the present invention is characterized in that the balancer is a baffle capable of stirring laundry.

Advantageous Effects of Invention According to the present invention, by providing a partition part, the adjusted water is stored predominantly on the leading end side of the washing tub which is the most distant part from the drive device in which the effect of unbalance of the washing tub is most noticeable. Thus, a larger weight can be applied to the washing tub during the dehydration operation, as compared with the case where the amount of the adjusted water is evenly distributed from the front end side to the base end side. As a result, it is possible to surely and quickly eliminate the imbalance of the washing tub during the dehydration operation. As a result, not only the amount of adjusted water can be saved, but also the time and opportunity required to inject the adjusted water can be effectively reduced, and the delay of operating time due to uneven distribution of laundry can be effectively avoided. You can
Further, according to the present invention, in which the partition part has an inclined surface inclined so as to gradually approach the rotation center of the drum from the front end side to the base end side of the washing tub, the adjusted water is centrifuged by the rotation of the drum. By the force acting, the water is preferentially stored on the tip side of the washing tub, so that the balancer action can be effectively exerted with a smaller amount of adjusted water, and the amount of adjusted water can be saved and the water injection time can be reduced. It also contributes to shortening the operating time by shortening.

Further, according to the present invention in which the balancer is a baffle, it is possible to obtain both functions of adjusting the balance of the washing tub and stirring the laundry by scraping it up.

<First embodiment>

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic cross-sectional view showing the configuration of the washing machine 1 of this embodiment. FIG. 2 is an operation explanatory view showing a partial vertical cross section of the washing machine 1 of the present embodiment.

The washing machine 1 of this embodiment can be suitably used, for example, in a coin laundry or a home, and includes a washing machine body 1a, an outer tub 3 having an axis S1 extending substantially horizontally, and a drum 2. A washing tub 1b, a water injection device 1c having a water receiving unit 5 and a nozzle unit 6, a drive device 40, and a control means (not shown) are provided.

The washing machine body 1a shown in FIG. 1 has a substantially rectangular parallelepiped shape. The front surface 10a of the main body 1a of the washing machine is formed with an opening 11 for loading and unloading laundry with respect to the drum 2, and an opening/closing lid 11a for opening and closing the opening 11 is attached.

The outer tub 3 is a bottomed tubular member disposed inside the washing machine main body 1a and is capable of storing washing water therein. As shown in FIG. 1, on the outer peripheral surface 3a of the outer tub 3, for example, an acceleration sensor 12 capable of detecting accelerations in the three directions of left, right, vertical, and depth is attached.

The drum 2 is a bottomed tubular member that is arranged coaxially with the outer tub 3 in the outer tub 3 and is rotatably supported. The drum 2 can store laundry therein, and has a large number of water passage holes 2b (see FIG. 1) on its wall surface 2a.

As shown in FIG. 1, the drive device 40 has a motor (not shown) as a main component, rotates a drive shaft 17 extending toward the bottom portion 2c of the drum 2, applies a drive force to the drum 2, and rotates the drum 2. Let

As shown in FIG. 1, the inner peripheral surface 2a1 of the drum 2 is provided with three baffles (water injection pipes) 7 as balancers at equal intervals (equal angles) in the circumferential direction. Each baffle 7 extends in the up-down direction from the base end portion 2c of the drum 2 to the tip end portion, and is formed so as to project from the inner peripheral surface 2a1 of the drum 2 toward the axis S1. Further, each baffle 7 is hollow, and the cross-sectional shape thereof is formed in an arc shape although not shown.

The water receiving unit 5 is configured by stacking water guiding troughs 5a in, for example, three layers in the radial direction toward the axis S1 of the drum 2, and is fixed to the inner peripheral surface 2a1 of the drum 2 as shown in FIG. .. The water guiding troughs 5a are provided in the same number as the baffles 7, and a water passage for allowing the adjusted water W to flow through any one of the baffles 7 is formed inside. A communication member 5a1 is connected to the inside of the baffle 7 as shown in FIG. 1, and the adjusted water W is supplied from the water receiving unit 5.

The water receiving unit 5 and the baffle 7 as described above are connected by a communication member 5a1.

The nozzle unit 6 is for pouring the adjusted water W individually into such a water guiding trough 5a. The nozzle unit 6 has three water injection nozzles 6a and a water supply valve 62a connected to each of these water injection nozzles 6a. The water injection nozzles 6a are provided in the same number as the water guiding troughs 5a, and are arranged at positions where water can be injected into the respective water guiding troughs 5a. In this embodiment, tap water is used as the adjusted water W. Further, as the water supply valve 62a, it is also possible to adopt a direction switching water supply valve.

With such a configuration, in the dehydration process in which the drainage valve 50a is opened and the wash water in the outer tub 3 is discharged from the drainage port 50, the water injection unit 6a of any one of the nozzle units 6 receives water from the water receiving unit 5. The adjusted water W poured into the water guiding trough 5a flows into the baffle 7 via the communication member 5a1. For example, when the adjusted water W is injected from any of the water injection nozzles 6a, the adjusted water W flows from the water guiding trough 5a into the baffle 7 via the communication member 5a1 as shown by the arrow in FIG. When the drum 2 is in a high-speed rotation state, the adjusted water W that has flowed into the baffle 7 clings to the inner peripheral surface 2a1 of the drum 2 and accumulates due to centrifugal force. This increases the weight of the baffle 7 and changes the balance of the drum 2. Thus, the baffle 7 has a pocket baffle structure capable of storing the adjusted water W by centrifugal force. Then, when the rotation speed of the drum 2 decreases near the end of the dehydration process, the centrifugal force in the baffle 7 is gradually attenuated, the adjusted water W flows out by gravity, and drains out of the outer tub 3 via the drain pipe 5. To be done. At this time, the adjusted water W flows into the outside of the pulsator through the opening 71. Therefore, the adjusted water W is drained without wetting the clothes in the drum 2.

Here, in the washing machine 1 according to the present embodiment, the drive device 40 is arranged on the base end 1e side and the tip 1d side is opened, and the washing tub 1b is arranged along the axis S1 direction of the washing tub 1b. A plurality of hollow balancer baffles 7 arranged on the inner peripheral surface 2a1 of the drum 2 which is the inner peripheral surface of the tank 1b, and a water injection device 1c for individually injecting the adjusted water W into each of the baffles 7 are provided. The washing machine 1 is characterized in that it has a structure that allows the injected adjusted water W to be retained preferentially from the tip 1d side of the washing tub 1b. Hereinafter, a specific configuration of the present embodiment will be described focusing on the configuration of the baffle 7 that is the balancer.

The baffle 7 is a partition part 71 capable of retaining the adjusted water W on the tip 1d side by suppressing the flow of the adjusted water W injected from the tip 1d side of the washing tub 1b to the base end 1e side by the water injection device 1c. The outlet 72 for discharging the injected adjusted water W from the side of the base end 1e of the washing tub 1b.

The partition part 71 is mainly composed of an inclined wall 73 provided from an outer wall so as to face a direction inclined from the axial direction. The surface of the inclined wall 73 is an inclined surface 74 that gradually inclines toward the center of rotation of the drum from the tip 1d side to the base 1e side of the washing tub 1b.

The outlet portion 72 is capable of discharging the adjusted water W, which has been injected from the 5a1 constituting the water injection device 1c by a predetermined amount or more, from the base end 1e side of the washing tub 1b.

Then, FIG. 2 schematically shows the behavior of the baffle 7 to which the adjusted water W is injected plural times during the dehydration process. Thus, in the same figure, each injection of the adjusted water W is shown in cross section. Since the adjusted water W is concentrated near the tip 1d of the baffle 7 in the first water injection, the adjusted water W is preferentially concentrated on the tip 1d of the baffle 7 even with the smallest amount of water injection. Therefore, the amount of water injected into the baffle 7 is small, in other words, the number of times water is injected into the baffle 7 can effectively eliminate at least the eccentricity of the washing tub 1b. Note that the adjusted water W quantitatively increases as the number of times of water injection into the baffle 7 increases, but the influence on the washing tub 1b, that is, the degree of elimination of the eccentric unbalance, gradually decreases.

As shown in the figure, the baffle 7 is provided with an outlet 72 continuous with the tip 1d of the inclined surface 74 so that the regulated water W of a certain amount or more can be preferentially discharged to the outside of the washing tub 1b. There is. As a result, it is possible to prevent the baffle 7 from being filled with the regulated water W of a certain amount or more, and effectively avoid the erroneous control caused by the excessive water injection.

As described above, in the washing machine 1 of the present embodiment, the baffle 7 serving as a balancer is adjusted by suppressing the flow of the adjusted water W injected from the tip 1d side of the washing tub 1b by the water injection device 1c toward the base end 1e side. A partition part 71 capable of retaining the water W on the tip 1d side and an outlet part 72 capable of discharging the injected adjusted water W from the base end 1e side of the washing tub 1b are provided.

With such a configuration, by providing the partition portion 71, the adjustment water W is most distant from the drive device 40 in which the influence of the imbalance of the washing tub 1b is most noticeable, and the tip 1d of the washing tub 1b is the farthest. By predominantly storing the water in the side, it is possible to apply a greater weight to the washing tub 1b during the dehydration operation, as compared with the case where the same amount of the adjusted water W is evenly distributed from the tip 1d side to the base end 1e side. Has become. As a result, the imbalance of the washing tub 1b can be reliably and quickly eliminated during the dehydration operation. As a result, not only the amount of adjusted water W can be saved, but also the time and opportunity required to inject the adjusted water W can be effectively reduced, and the delay in operating time due to uneven distribution of laundry can be effectively avoided. I'm busy. As a result, if the washing machine 1 is installed in a coin laundry store, it contributes to the improvement of the rotation efficiency of the store by avoiding the delay of the operation time. Further, if the washing machine 1 is installed in the home, it avoids the delay of the driving time and contributes to the effective use of the user's time.

Further, in this embodiment, the balancer is the baffle 7, so that both functions of adjusting the balance of the washing tub 1b and stirring the laundry by scraping it up are realized.

Further, in the present embodiment, the partition portion 71 has the inclined surface 74 which is inclined so as to gradually approach the rotation center of the drum from the tip 1d side of the washing tub 1b toward the base end 1e side. Is preferentially stored on the tip 1d side of the washing tub 1b due to the centrifugal force generated by the rotation of the drum, so that the effect as a balancer can be effectively exhibited with a smaller amount of the adjusted water W, This is particularly useful for reducing the amount of adjusted water W and shortening the operating time by shortening the water injection time.

Hereinafter, another embodiment of the present invention will be described. In each of these embodiments, components corresponding to those in the above embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

<Second embodiment>

FIG. 3 is a schematic cross-sectional view showing the configuration of the washing machine 1 according to the second embodiment of the present invention. FIG. 4 is an operation explanatory view showing a partial vertical cross section of the washing machine 1 of the present embodiment.

The washing machine 1 of the present embodiment includes a washing machine main body 1a, a washing tub 1b including an outer tub 3 having an axis S1 extending substantially horizontally and a drum 2, a water receiving unit 5 and a nozzle unit 6. The point that the water injection device 1c, the drive device 40, and the control means (not shown) are provided is the same as in the first embodiment.

In the washing machine body 1a shown in FIG. 3, the front surface 10a faces slightly upward, so that the opening 11 for taking in and out the laundry with respect to the drum 2 is formed obliquely upward. The user opens and closes the opening/closing lid 11a that can be opened and closed from diagonally above. That is, the washing machine 1 according to this embodiment is a so-called diagonal drum type fully automatic washing machine in which the washing tub 1b is obliquely attached.

As for the washing machine 1 according to the present embodiment, similarly to the above-described embodiment, the drive device 40 is arranged on the base end 1e side and the tip 1d side is opened, and the washing tub 1b extends along the axis S1 direction. A plurality of hollow balancer baffles 7 arranged on the inner peripheral surface 2a1 of the drum 2, which is the inner peripheral surface of the washing tub 1b, and a water injection device 1c for individually injecting the adjustment water W into each of the baffles 7. Be prepared. Hereinafter, the baffle 7 as the balancer shown in this embodiment will be described.

This baffle 7 retains the adjusted water W on the tip 1d side by suppressing the flow of the adjusted water W injected from the tip 1d side of the washing tub 1b by the water injection device 1c to the base end 1e side as in the above embodiment. It has a partition part 71 that can be operated and an outlet part 72 that can discharge the injected adjusted water W from the side of the base end 1e of the washing tub 1b. Further, in the baffle 7 according to the present embodiment, the partition portion 71 is erected from the outer wall surface of the baffle 7 toward the inside, is positioned on the tip 1d side, and is preferentially stored in the preferential storage area 75a for storing the adjusted water W. It is characterized in that it is a partition wall 75 which is located on the base end 1e side from the priority storage area 75a via the outlet portion 72 and divides it into a discharge promoting area 75b for discharging the adjusted water W.

Then, FIG. 4 schematically shows the behavior of the baffle 7 to which the adjusted water W is injected a plurality of times during the dehydration process. As described above, also in the present embodiment, the adjusted water W is concentrated near the tip 1d of the washing tub 1b in the baffle 7, so that the adjusted water W can be supplied to the baffle 7 even with the smallest amount of water injection. That is, since the water is preferentially concentrated in the priority storage area 75a provided at the tip 1d of the washing tub 1b, a small amount of water is poured into the baffle 7, in other words, at least the number of times water is poured into the baffle 7 is washed. The eccentricity of the tank 1b can be effectively eliminated. Further, in the present embodiment, the adjusted water W quantitatively increases as the number of times of water injection into the baffle 7 increases, but unlike the above-described embodiment, the weight that can be added to the washing tub 1b is proportional to the number of times of water injection. It is going to rise. In addition, as in the above embodiment, the outlet 72 is provided with a partition wall so that the adjusted water W, which has been poured by the water injection device 1c in a certain amount or more, can be discharged from the base end 1e side of the washing tub 1b toward the discharge promoting region 75b. It is provided continuously from the tip 1d.

As described above, even in the washing machine 1 according to the present embodiment, as in the above embodiment, it is possible to effectively reduce the time and opportunity required to inject the adjusted water W, and delay the operation time due to uneven distribution of laundry. Can be effectively avoided.

Particularly, according to the present embodiment, it is possible to obtain the effect that the balance adjustment can be performed with less adjustment water W even with a simple configuration.

As shown in FIG. 5, the pulsator 4 is an ordinary one having a substantially disc-shaped pulsator main body and a plurality of blades formed on the upper surface of the pulsator main body. The pulsator 4 as described above agitates the wash water stored in the outer tub 3 to generate a water flow.

As shown in FIG. 5, the drive device 40 is mainly composed of a motor (not shown), and rotates a drive shaft 17 extending toward the bottom portion 2c of the drum 2 to apply a driving force to the drum 2 and the pulsator 4 to drive the drum 2. Rotate 2 and pulsator 4. The washing machine 1 mainly rotates only the pulsator 4 in the washing process, and integrally rotates the drum 2 and the pulsator 4 at a high speed in the dehydration process.

As shown in the figure, the washing machine 1 according to the present embodiment is similar to the above-mentioned embodiments in that the drive device 40 is arranged on the base end 1e side and the tip 1d side is opened, and the washing tub 1b. Baffles 7 which are a plurality of hollow balancers arranged on the inner peripheral surface 2a1 of the drum 2 which is the inner peripheral surface of the washing tub 1b along the axis S1 direction, and the adjusted water W is individually supplied to each of the baffles 7. A water injection device 1c for injecting water is provided, and the adjusted water W is retained on the tip 1d side by suppressing the flow of the adjusted water W injected from the tip 1d side of the washing tub 1b to the base end 1e side by the water injection device 1c. It has a partition part 71 to be obtained and an outlet part 72 from which the poured adjusted water W can be discharged from the base end 1e side of the washing tub 1b.

Here, the baffle 7 included in the washing machine 1 according to the present embodiment will be described below.
