Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a continuous VE washing machine that is equipped with a plurality of washing tanks and rinsing tanks, and washes and rinses the laundry by sequentially moving the items to be washed into the tanks. It is.

[Conventional technology]

As shown in FIG. 5, the conventional tunnel washing machine has a spiral partition 32 that is twisted in the axial direction inside the swinging drum 31.
The washing tank 33 is divided into a large number of washing tanks 33 and rinsing tanks 34, and the washing tank 33 on the front side is provided with an input port 35 for items to be washed, and the rinsing tank 34 on the rear side is connected to a dewatering device 36.

In this continuous washing machine, the swinging drum 31 is rotated 360°.
By rotating as described above, the items to be washed, which have been input from the input port 35, are moved to the adjacent tank by the rotation of the swinging drum 31 and the guidance of the partition 32, and then the drum 31 is moved approximately 18
Washing and rinsing of the items to be washed are performed by rotating the washing machine in the range of 0'' to 300@.

In addition, in each rinse tank 34, in order to reuse the discharged rinse water in the washing tank 33 and rinse tank 34 in the previous process,
A water circulation circuit 37 is connected to supply rinsing water from the drainage tank to a predetermined tank.

[Problem to be solved by the invention]

In the continuous washing machine with the above structure, the washing tank 33 and the rinsing tank 34 are integrally connected, and in order to rotate in the same direction and move the laundry, the waste water of the washing tank 33 from pre-washing and main washing is removed. It moves to the rinsing tank 34 together with the items to be washed. For this reason,
Next, rinsing in the rinsing tank 34 until the rinsing water becomes clear has the disadvantage that a large amount of water is required and the working time is extremely long.

Furthermore, in order to obtain sufficient rinsing capacity, it is necessary to provide a large number of rinsing tanks, which causes the problem that the overall length of the apparatus increases.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a continuous washing machine that eliminates the movement of washing water from the washing tub to the rinsing tub due to the laundry to be washed, and that allows efficient rinsing at low cost.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention divides the washing tub and the rinsing tub in the above-mentioned connected washing machine, and separates the oscillating drum between them. A dehydration tank is provided which is rotated by the spindle, and this dehydration tank is provided with an opening through which the items to be washed are delivered to and from the adjacent washing tank and rinsing tank. A structure was adopted in which spiral blades were twisted in the axial direction in the same direction as the drum partitions.

Moreover, as a second means, in the above structure, a structure in which a dehydration tank is provided between the rinsing tank and the rinsing tank is adopted.

In addition, in the above structure, the height of the spiral blade of the dehydration tank may be formed to gradually increase from the receiving port for the washed items toward the transfer port.

[Effect]

In the tunnel washing machine with the above structure, the items washed in the washing tank are loaded into the dehydration tank from the receiving port, and then the dehydration tank is rotated in the opposite direction of the rocking drum to dehydrate the items, and the laundry is dehydrated. Remove the washing water from the items being washed. When the dehydration is completed, the dehydration tank is rotated in the same direction as the +1 moving drum, and the items to be washed are moved from the dehydration tank to the rinsing tank by the guiding action of the spiral blades.

On the other hand, if a dehydration tank is provided between the rinsing tanks as in the second method, rinsing can be performed using only fresh water in the rinsing tank after the dehydration tank, further improving rinsing efficiency.

In addition, by changing the height of the helical blades, the height of the blades is smaller on the receiving side, making it easier to receive the items to be washed from the washing tank, and the guiding force of the helical blades gradually increases as you move toward the transfer port. Therefore, the items to be washed can be reliably delivered to the rinsing tank.

[Example] Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 to 3, the continuous washing machine of the embodiment includes a washing drum 1, a dehydration tank 2, and a rinsing drum 3.
It consists of , which are arranged in series.

The washing drum 1 and the rinsing drum 3 are rotatably supported on a pedestal 4 via a guide ring 5 and a support roller 6, and are driven to rotate in the same direction by a drive motor 7.

On the other hand, as shown in FIG. 4, the dewatering tank 2 is rotatably supported on a pedestal 4 by support rollers 6 like both drums, but it has a forward and reverse drive motor different from the drive motor 7 for the drums 1 and 3. It is rotationally driven by a drive motor 8 which can be used.

The washing drum 1 is equipped with a washing article input port 9 on the front side, and inside thereof a plurality of washing tubs 11 are formed by spiral partitions 10 twisted in the axial direction. A washing outlet 12 is formed. Moreover, the drum 3 for Suzuki is equipped with a load 13 to be washed on the front, and inside,
Spiral partition 1 twisted in the same direction as the partition 10 above
A plurality of rinsing tanks 15 are formed by 4, and an outlet 16 for discharging items to be washed is provided on the rear surface.

On the other hand, a receiving port 17 facing the laundry outlet 12 of the washing drum 1 is formed on the front surface of the dehydration tank 2, and a transfer port 18 facing the laundry material outlet 13 of the drum 3 for sea bass is formed on the rear surface. The above-mentioned partition 10.1 is provided inside the dehydration tank 2.
A helical blade 19 is provided which twists in the axial direction in the same direction as 4.

The front and rear ends of this spiral blade are continuous with the receiving port 17 and the crossing port 18, respectively, and the height of the blade is formed to gradually increase from the front side to the rear side. .

In addition, the washing tank 11 and each rinse tank 15 are provided with a drain port 20 for washing water and rinsing water, respectively, and a drainage tank 21 for receiving the rinsing water is provided so that the rinsing water can be reused as in the conventional structure. A water circulation circuit 22 is connected thereto.

This embodiment has the structure as described above, and its operation will be explained next.

When the items to be washed are inputted from the input port S, the washing drum 1 is swung in a range of about 180° to 300°, and the detergent and the items to be washed are stirred inside the washing tank 11 to perform pre-washing and wood washing. . 1
When the two washing steps are completed, the washing drum 1 is moved 360'
By rotating the drum as described above, the items to be washed are sequentially moved to the scale tank by the rotation of the drum and the guidance of the spiral partition 10.

When the items to be washed are put into the dehydration tank 2 from the outlet 12 of the washing tank 11, the dehydration tank 2 is rotated in the opposite direction to the washing drum 1 (and the rinsing drum 3). As a result, the objects to be washed are stopped from moving in the circumferential direction by the spiral blades, and are also pressed against the inner peripheral surface of the dehydration tank 2 by centrifugal force, and the washing water contained inside is removed. .

This dehydration does not need to be performed at high speed. That is,
As the rotational speed of the dehydration tank increases, the water content of the items to be washed decreases exponentially due to centrifugal force, so a large dehydration effect can be obtained even at low rotational speeds. For example, the diameter of the dehydration tank is 1500~
In the case of 2000 fences φ, a sufficient dewatering effect can be achieved at an intermediate speed of about 100 to 70 R/min. In addition,
In this intermediate speed range, the centrifugal nozzle j applied to the dehydration tank 2 is about 6 to 8 G, so it is preferable to provide a roller to prevent jumping around the outer periphery of the dehydration tank.

When the dehydration is completed, the dehydration tank 2 is rotated in the opposite direction, that is, in the same direction as the washing drum 1 and the rinsing drum 3. As a result, the items to be washed are guided by the spiral blades 19 and moved rearward, and sent into the rinsing tank 15 through the transfer port 18. In this state, when the item is placed in the rinsing tank, most of the unwashed water has been removed from the inside of the item, so next, new water is poured into the rinsing tank 15 to rinse it out. There is less dirt in the rinsing water, and rinsing can be completed in a short time.

Furthermore, since the rinsing water becomes less contaminated, the amount of fresh water supplied to the final rinsing tank 15 can also be saved.

In fact, when the continuous washing machine of the above embodiment was used to wash laundry items, it was possible to save more than 20% of the rinsing time and the cost of using Shimizu compared to the conventional structure shown in FIG.

Further, as the detergent stains contained in the rinse water are reduced as described above, the number of rinse tanks can be left in comparison with the conventional structure. In other words, in the conventional structure, the front rinse tank collects dirty washing water coming from the washing tank.
In contrast, in the washing machine of the embodiment, the washing water in the washing tank is shut off by spin-drying tank 2, so the rinsing tank is used only for rinsing. Therefore, sufficient rinsing can be performed even with a small number of baths.

(Effects of the Invention) As explained above, in this invention, a dehydration tank is provided between the washing tank and the rinsing tank, and the dirty water in the washing tank is removed by the dehydration tank. This has the effect of saving water and shortening rinsing time.

Furthermore, since the structure is such that the rinsing tank is isolated from the washing tank and only rinsing is performed, the number of rinsing tanks can be reduced compared to the conventional structure, and the overall length of the device can be made compact.
