Description

The present invention relates to a commercial laundry dewatering and drying apparatus and an arrangement system that automatically perform processing from washing to drying of laundry.

  Washing and rinsing equipment for business that performs washing and rinsing on sheets and clothing (hereinafter referred to as clothing) used for work in hospitals and nursing care welfare facilities, etc., followed by automatic dehydration / drying. However, it is known from Patent Documents 1 and 2, for example.

The apparatus disclosed in Patent Document 1 is supported by a pair of left and right bearings on both bottom surfaces of a cylindrical drum for washing and dewatering, and drying air is provided on the bottom surface on one side of the drum. Then, it is supplied into the drum through the opened opening for drying. An opening is provided in the drum circumferential curved surface, and the laundry is taken in and out through a door formed in one place of the outer body covering the outside of the drum.

In addition, the apparatus disclosed in Patent Document 2 is supported in a cantilevered manner by a support shaft on one bottom surface side of a cylindrical drum, performs washing and dehydration, and also heats the outside air from the bottom surface on the other side of the drum. It is designed to be fed into the drum. In addition, a loading port for loading laundry is formed on the bottom surface on the other side, and the laundry is loaded and unloaded through a door formed at one location on the outer trunk.
In such a laundry dehydrating and drying apparatus, the door provided on the outer trunk is common in and out of the laundry, and the clothes that have been washed and the clothes before washing, etc. are spaced simultaneously or in time series. Share In addition, an operator who puts dirty clothes or the like into the washing / dehydrating / drying apparatus and an operator who takes out the washed clothes from the apparatus also work in the same space.

On the other hand, Patent Document 3 discloses a washing machine in which an inlet port for putting dirty clothes and the like and an outlet after washing are separately provided. The bottom surfaces of a large number of cylindrical drums are connected to each other through partition plates, and the shafts of both ends are hollowed to form a passage for clothing or the like, and are transferred from the drum to the drum. Note that this apparatus does not perform dehydration and drying, and it is necessary to prepare a separate dehydrator and dryer, and to transfer the clothes and the like after rinsing to the dryer. The dehydration process is to rotate water-containing clothing etc. at high speed, and with a shaft having a hollow with a diameter large enough to pass clothing etc., the bearing diameter is large and it is difficult to maintain mechanical strength, Moreover, since it is necessary to perform a drying process at the temperature of about 60 degree | times for a long time in order to prevent damage to clothing etc., it is difficult to incorporate in the same apparatus.

As an apparatus for performing only drying, Patent Document 4 discloses an apparatus in which an entrance door and an exit door are provided on both bottom surfaces of a cylindrical drum. Since the bacteria are almost sterilized after the washing / rinsing is completed, the apparatus is not in an environment where contaminated clothing or the like before washing exists in the entrance door and the exit door and the environment. Since the drying process is a process in which dry air is applied to the drained clothes and the like, the number of rotations of the drum is lower and the bearing diameter is larger than the dehydration process.

In this example, the left end side support shaft part 18b is formed longer than the right end side support shaft part 18a, and is rotated by the drive unit 7 (one-dot broken line in FIG. 2).

FIG. 6 is a system explanatory diagram of the air supply / discharge unit 3. The air supply / exhaust section 3 circulates heated air or outside air into the drum 6 through an air supply port 11 a and an air discharge port 11 b formed at five locations on the outer cylinder within the range directly above the drum 6. The air supply unit 3a and the air discharge unit 3b are provided. The pressure air air supply 3a is fed from the blower 33, through the air heater 35 by the ventilation passage 34a, and 34b communicating to transfer to the air supply port 11 a. The air supply port 11 a and air passage 34b of the outer cylinder 5 are connected by the flexible tube 36a.

On the other hand, the air discharge portion 3b of the air discharged from the air discharge port 11 b, transferred through the filter device 38 to the air exhaust port 39 to dissipate into the atmosphere by passing it through the air passage 37a. The filter device 38 includes an upstream first filter 40 and a downstream second filter 41 on the air discharge path of the air discharge portion 3b, and the air discharge port 11b and the ventilation path 37a of the outer body 5 are flexible. They are connected by a pipe 36b.

The 1st filter 40 is a filter by the cylindrical metal-mesh 40b arrange | positioned in the standing outer cylinder 40a. The outer cylinder 40a is provided with a vibrator 40c for vibrating the wire mesh 40b. When the air flowing into the outer cylinder 40a passes through the eyes from the inner periphery of the wire mesh 40b and reaches the outer periphery, lint (cotton dust) is filtered out. When the metal mesh 40b is vibrated by the vibrator 40c, the lint accumulated on the inner peripheral surface of the cylindrical metal mesh 40b is separated from the metal mesh 40b and falls downward.
The reason why the wire mesh 40b is used as a filter is that the vibration of the vibrator 40c is transmitted to the entire wire mesh 40b and the lint can be dropped.

The 2nd filter 41 is a filter by the cloth bag 41b inserted in the cylindrical holding frame 41a. When the air flowing inward of the cloth bag 41b passes through the cloth of the cloth bag 41b, the cloth bag 41b filters out lint contained in the air onto the inner surface thereof. The lint filtering capacity of the second filter 41 and the first filter 40 may be substantially equal. The cloth bag 41b is surrounded by a casing 41c having an opening 41c1 for taking in and out the bag. A ventilation path 37b for diffusing the filtered air from the casing 41c to the atmosphere extends upward, and an upper end opening of the ventilation path 37b is an exhaust port 39.

The outer cylinder 40a on the first filter 40 side is communicated with the ventilation path 37b through a short-circuit ventilation path 37c, and a first on-off valve 42 for opening and closing the short-circuit ventilation path 37c is provided. A second opening / closing valve 43 for opening and closing the lower end opening of the outer cylinder 40a is provided in the ventilation path 37d connecting the outer cylinder 40a and the casing 41c. The lint that has fallen from the wire mesh 40 b due to the vibration of the vibrator 40 c falls to the casing 41 c via the second on-off valve 43.

Next, the example of the arrangement | positioning system which the above-mentioned commercial laundry dehydration drying apparatus 100 used is demonstrated.
In FIG. 7, the work room is divided into a dirty room h1 into which clothes and the like are carried and a clean room h2 in which the environment is cleaned, with the partition wall i1 as a boundary. A through hole i2 is formed in the partition wall part i1, and most of the commercial laundry dehydrating and drying apparatus 100 is disposed in the dirty room h1 to close the through hole i2. The opening 12a is disposed on the clean room h2 side, and the opening 12b is disposed in the clean room h2 through the through hole i2. The blower 33 of the apparatus 100 installed in this manner sucks outdoor outdoor air through the intake indoor duct 33a, and the air discharged from the exhaust vent 39 is dissipated outdoors through the exhaust indoor duct 39a. I am doing so. Thus, the clean room h2 is a space separated from the dirty room h1 unless the door 12a or the outlet 12b is opened at the same time when the door of the passage j1 is closed.

In the operation stop state of the commercial laundry dehydrating and drying apparatus 100, the opening 12a of the outer drum 5 and the opening 26a or 26b of the drum 6 are in the facing arrangement state shown in FIG. The operator opens the opening 12a of the outer body 5 and the opening 26a or 26b of the drum 6 facing the opening 12a. The clothes to be processed and the like carried into the dirty room h1 are put into the drum 6 and 27b is closed.

Next, the drum 6 is rotated halfway to open the opening 26b or 26b of the other chamber e2 or e1, and after further putting clothes or the like, the watertight doors 13 and 26b are closed.

Next, the commercial laundry dehydration drying apparatus 100 is started. Washing, rinsing, dehydration and drying are performed continuously. In the washing process, first, detergent or water is supplied into the outer cylinder 5 from a water supply means and a detergent supply means (not shown) and stored in the lower part of the outer cylinder 5. Next, by actuating the drive unit 7 and rotating the drum 6, clothes and the like are agitated, washed and rinsed in the drum 6.
When the washing process is completed, the rotation of the drum 6 is stopped, the drain valve 10 is opened, and the washing water in the outer body 5 is discharged to the outside through the drain pipe. Next, under the state where the drain valve 10 is opened, the number of rotations of the drum 6 by the drive unit 7 is increased to perform dehydration processing. Moisture such as clothes in the drum 6 is scattered by the centrifugal force to the outer body 5 side through the through-hole d1 of the drum 6, collected in the recess 8b1, and drained to the outside through the drain valve 10.

When the dehydration process is completed, the drive unit 7 lowers the rotation of the drum 6 to start the blower 33 and starts air heating by the air heater 35. The heated air is sent into the outer body 5 through the ventilation path 34b and the air supply port 11a, and is supplied into the drum 6 through the through hole d1 in the front portion of the outer peripheral wall portion 20 of the drum 6, and the rotary clothing and the like. When contacted, moisture of clothes and the like evaporates. At this time, the first on-off valve 42 is opened, and the second on-off valve 43 is closed.

The heated air in the drum 6 whose humidity has increased due to evaporation of water is discharged into the ventilation path 37a of the air discharge portion 3b through the air discharge port 11b while the lint generated by drying is involved. Since the second on-off valve 43 is closed, the air in the ventilation path 37a passes through the mesh of the wire mesh 40b of the first filter 38, and then flows down through the ventilation path 37c and the ventilation path 37b in this order from the exhaust port 39. Dissipated. During this time, lint is accumulated on the inner surface of the wire mesh 40b.

When the drying process is completed, the cooling operation is performed to stop the heat generation of the air heater 35 and continue the operation of the blower 33. Similar to the drying process, the drum 6 is rotated by the drive unit 7. The first on-off valve 42 is closed, the second on-off valve 43 is opened, and the vibrator 40c is operated. As a result, unheated air continuously flows in the drum 6 to cool clothes and the like. Further, the air flowing down in the ventilation path 37a passes through the inner peripheral side of the wire mesh 40b, and then flows down to the casing 41c through the ventilation path 37d. At this time, the lint is separated / dropped from the inner periphery by the vibration of the wire mesh 40b and reaches the casing 41c. In the casing 41c, this lint is filtered out into the cloth bag 41b. When cooling is completed, the blower 33 is stopped. At this time, the wire mesh 40b is cleaned, and the ventilation path of the air supply / exhaust unit 3 is also in a state ready for the drying process with the heated air such as the next clothing.

Thereafter, the positions of the opening 12b of the outer body 5 and the opening 26a or 26b are overlapped to bring the lock mechanism 13a2 and the lock mechanisms 30a and 30b into an unlocked state. The watertight door 13 is opened in the clean room h2, the door body 27a or 27b of one of the chambers e1 or e2 overlapping therewith is opened, and clothes and the like in the chamber e1 or e2 are taken out into the clean room h2. After the drum 6 is rotated halfway, the clothes and the like in the other chamber e1 or e2 are taken out into the clean room h2. When the extraction is completed, a signal notifying the completion is displayed on the operation panel 44 on the dirty room h1 side.

The worker on the dirty room h1 side opens / closes the opening 12a of the business laundry dehydration drying apparatus 100 after receiving the completion of the operation panel 44, and starts the next laundry work.

As described above, in the commercial laundry dehydration and drying apparatus 100, the entrance for feeding dirty clothes and the like and the exit for taking out the clothes and the like after dehydration and drying are provided so as to sandwich the peripheral surface of the drum 6 from both sides. ing. Therefore, if one side is facing the dirty room h1 and the other side is in the clean room h2, and the commercial laundry dehydrating and drying apparatus 100 is arranged at the partition position between the dirty room h1 and the clean room h2, washing with dirty clothes and the like is completed. Clothing and the like can be distinguished and processed.

Further, an opening 12 a is formed in the outer body 5 at a position facing the peripheral surface of the drum 6. The opening 12a is provided for putting laundry into the drum 6 through the opening of the drum 6. In addition, an opening 12b is formed in the outer body 5 at a position facing the peripheral surface of the drum 6 and opposite to the opening 12a. The opening 12b is provided for taking out the laundry in the drum 6 outward. On the other hand, the drum 6 is a bearing in which support shaft portions 18a, 18b projecting outward from the circular end plates 19a, 19b are respectively fixed to the right side plate 9a and the left side plate 9b of the outer cylinder 5 (FIG. 1, left side). Since the bearing is supported in a doubly supported manner on the bearing 32 of the face plate 9b and has a small bearing radius and a doubly supported bearing, the structure can be simplified even for high-speed rotation due to dehydration.

Furthermore, since the air supply port 11a and the air discharge port 11b are provided above the openings 12a and 12b in the outer body 5, the air supply port 11a and the air discharge port 11b are not immersed in the washing water.
In addition, since the drum 6 has the opening 26a or 26b at a point-symmetrical position around the rotation shaft 18, the rotation balance can be easily obtained.

Further, since the partition plate 25 is fixed at the diameter position and the interior is divided into two chambers e1 and e2, when the dirty clothes are put in, as shown by the arrow a in FIG. Throw towards the bottom. On the other hand, when taking out clothes, etc., as shown by the arrow b in FIG. 5, the clothes can be taken out by using the partition plate 25 like a slide, and there is no occurrence of undrawn parts.

Further, when washing of clothes or the like is repeated, dust in the cloth bag 41b accumulates and becomes clogged and the air volume decreases, so that lint is taken out at a predetermined cycle. On the other hand, since the wire mesh 40b is always cleaned before the drying process, the lint processing of the cloth bag 41b need not be performed every time before the drying process.

Since clothes and the like taken out from the take-out port 12b are cleaned by a washing process, they are isolated from the dirty room h1. The clothing and the like are finished in a clean environment in the clean room h2.

Openings 12a and 12b are respectively provided at positions where the drum 6 is half-rotated with respect to the outer cylinder 5, and a watertight door 13 is provided on each of the openings 12a and 12b. The discharge opening can be installed, and the drum openings 26a and 26b can be directed to both the openings 12a and 12b by only rotating the drum 6 halfway.
For this reason, a series of processes of washing, dehydration, and drying can be completed in one drum 6, and there are separate spaces for dirty clothes and the like before washing and clean clothes and the like after drying is completed. It becomes possible to handle with.

The drum 6 can be rotated only when the openings 12a, 12b and the openings 26a, 26b are all closed and locked by the lock mechanisms 13a1, 13a2, 30a, 30b. Further, the take-out port 12b is preferably configured such that when one of them is opened by the lock mechanisms 13a1 and 13a2, the other is not opened.

  In the commercial laundry dehydrating and drying apparatus 100 of the above embodiment, the drum 6 is partitioned into two chambers e1 and e2 by the partition plate 25. However, the partition plate 25 may be omitted and the drum 6 may be a single chamber. . In this case, one of the openings 26 a and 26 b of the drum 6 is omitted, and the omitted portion is covered with the outer peripheral wall portion 20. For example, if the opening 26b is omitted, when the drying process is finished and the drum 6 is stopped, the drum 6 is automatically stopped with one opening 26a facing the opening 12b that is the take-out port. When the rotation is controlled and the clothes and the like in the drum 6 are taken out into the clean room h2 in this stopped state and the opening 12b as the take-out opening is closed, the opening 26a faces the opening 12a as the input opening. The rotation is controlled so that 6 automatically stops.
