(Prior Art) Referring to FIG. 3, a dehydrator proposed in Japanese Patent Laid-Open No. 62-66898 will be described. 36 is a mount, which is installed on the work floor. A pillar 37 is a component of the gantry 36, and a plurality of pillars 37 are arranged. 38 is a deck composed of a lattice-like member fixed to the pedestal 36, 39 is a deck plate composed of a perforated plate fixed to the deck 38, 40 is a large number of porous or mesh-like small voids through which water can pass. A wide endless conveyor belt for conveyance having a belt 41 is a roll for driving the conveyor belt 40. 42 is a cylindrical basket, 43 is an input port formed on the top of the basket 42, and 44 is a basket
The guide is fixed to 42 and engages with the pillar 37.

46 is a lifting drive unit fixed to the pedestal 36 and engaged with the basket 42 by a chain or the like, 47 is a hydraulic cylinder fixed to the pedestal 36, 48 is a hydraulic device including an oil tank for the cylinder 47 and a hydraulic circuit, 49 Is a hydraulic pump for the hydraulic device 48, 50 is a drive motor for the hydraulic pump 49, 51 is a piston rod of the cylinder 47, 52 is a bowl-shaped member fixed to the piston rod 51,
53 is a membrane made of an elastic film that is in close contact with the opening of the bowl-shaped member 52 and encloses water, 54 is a water supply port mounted on the bowl-shaped member 52, and 55 is air attached to the bowl-shaped member 52. Exit, 56
Is a water sealed between the bowl-shaped member 52 and the membrane 53, and 57 is a ring that holds the membrane 53 in close contact with the bowl-shaped member 52, and is a fixture that is bolted to the bowl-shaped member 52. Reference numeral 58 is a continuous water washing machine arranged before the dehydration process, 59 is a discharge conveyor arranged after the dehydration process and connected to a drying machine, etc. .

Now, the dehydrator is in the state shown in FIG. 3, that is, the belt 40 is stopped,
With the basket 42 in the lowered position and the piston rod 51 in the raised position, a substantially fixed amount of laundry 60 is thrown into the basket 42 from the continuous water washing machine 58. Next, when the hydraulic device 48 is actuated in response to the completion signal from the continuous water washing machine 58, the piston rod 51 is lowered and the membrane 53 pressurizes the laundry 60 as shown in FIG.

When dehydration is performed for a certain period of time in this state, and a timer (not shown) times out, the circuit of the hydraulic device 48 switches and the piston rod 51 rises. Then, when the lifting device 46 is activated,
The basket 42 engaged with the chain or the like is raised as shown in FIG. After that, the roll 41 that drives the conveyor belt 40 rotates, and the crushed laundry 60 is transferred onto the discharge conveyor 59. Next, when the transport conveyor 40 is stopped, the basket 42 is lowered to the initial state shown in FIG.

(Problems to be solved by the invention) However, in the conventional dehydrator shown in FIG. 3, a dust control product, such as a mat or mop, which contains a lot of lint (lint, dust, etc.) during the pressurization shown in FIG. Has a large amount of lint, and when water containing a large amount of lint passes through the conveyor belt 40 during pressing, the lint causes the surface of the conveyor belt 40 to be clogged. When the conveyor belt 40 is clogged in this way, the washing liquid that is being squeezed does not pass through the wide conveyor belt surface, the residual water content of the laundry 60 becomes high, and the energy of the dryer in the subsequent process is greatly increased. There was a problem such as the cost.

The present invention is intended to solve the above problems by providing a means for removing lint from the surface of the conveyor belt.

(Means for Solving the Problem) Therefore, the present invention is an apparatus for dewatering water from laundry such as clothes after washing by squeezing water, placing the laundry at the time of dewatering and carrying out the laundry after carrying out the dewatering. A fluid injection nozzle having an opening facing downward is provided inside a lower belt portion of a wide endless conveyor belt having a large number of water-possible small voids, which is a means for solving the problems. Is.

(Operation) On the surface of the upper belt portion of the conveyor belt stopped on the bottom surface of the basket, the washed laundry is put and accumulated, and the press plate is lowered to dehydrate. After the spin-drying, the basket moves up while the laundry remains on the conveyor belt, and the conveyor belt rotates to discharge the laundry to the next step. At the same time, when a fluid such as water or compressed air is jetted from the inside of the lower belt portion of the conveyor belt from the fluid jet nozzle, the lint adhering to the surface of the conveyor belt drops downward due to the jetted fluid from the back surface, When the lower belt portion eventually reaches the upper belt portion, the conveyor belt is such that lint does not adhere to it with all the small voids opened.

(Embodiment) The present invention will be described below with reference to the embodiments of the drawings. FIG. 1 and FIG. 2 show an embodiment of the present invention. The members denoted by reference numerals 36 to 44 and 46 to 60 in FIGS. 1 and 2 are all the same as those shown in FIG. 3, and therefore detailed description thereof will be omitted here.

The feature of the present invention is to place the laundry 60 at the time of dehydration,
A wide endless conveyor belt having a large number of water-permeable porous or mesh-like small voids for carrying out laundry after dehydration
Inside the lower belt portion 40a at 40, the fluid ejection nozzle 1
The point is that 0 is provided.

FIG. 2 is an enlarged view of a main part in FIG. 1, in which the injection nozzle 10 is arranged across the width direction inside the lower belt portion 40a of the wide endless conveyor belt 40. A slit or a large number of holes 10a provided at appropriate intervals are opened diagonally downward in the width direction, and from the slits or holes 10a toward the inner surface of the lower belt portion 40a of the conveyor belt 40. ,
A fluid 11 such as water or compressed air is jetted from diagonally above.

Next, the operation will be described. From the continuous water washing machine 48 as shown in FIG. 1, a substantially fixed amount of laundry 60 is put on the endless conveyor belt 40 stopped on the lower surface of the descended basket 42.
It is thrown in through 43 and deposited. Then, when the hydraulic device 48 operates, the piston rod 51 descends to squeeze the laundry 60 through the membrane 53 to dehydrate it. The water containing the lint 12 resulting from the dehydration flows down to the bottom of the pedestal 36 through a large number of small voids of the conveyor belt 40 and is drained. Then, by raising the membrane 53 and the basket 42, the laundry 60 is left on the conveyor belt 40 in a dehydrated state. Then the conveyor belt 42
1 by rotating in the direction of the arrow in FIG.
Is conveyed and discharged onto the discharge conveyor 59.

However, in this case, lint (lint, dust, etc.) is the second
As shown in the figure, it remains attached to the surface of the conveyor belt 40.
At this time, when water or compressed air is jetted from the inside of the lower belt portion 40a of the conveyor belt 40 through the slits or holes 10a of the fluid jet nozzle 10 by an electromagnetic valve or the like not shown, the lint adhered to the surface of the belt 40 It is possible to prevent 12 from being separated from the surface of the lower belt portion 40a and dropping like lint 13 in FIG. 2 to obstruct the conveyance belt 40 surface due to lint and to prevent dehydration.

(Effects of the Invention) As described in detail above, the conveyor belt of the present invention has a large number of small gaps through which water can pass, so that water discharged during the dehydration of laundry falls downward through the small gaps. , Lint remains on the surface of the conveyor belt. However, when water or compressed air is jetted from the fluid jet nozzle which is provided inside the lower belt portion of the conveyor belt and has the opening portion facing downward, the lint is blown off and removed from the surface of the lower belt portion of the conveyor belt. Therefore, in the next dehydration process, the endless conveyor belt can keep all the small voids open, and the drainage of dehydrated water from the belt surface is insufficient as in the conventional case, resulting in a residual water content of the laundry. There is no problem that the cost becomes high and a great deal of drying energy is required in the subsequent process.
