Description

An embodiment of the present invention relates to a coin laundry device capable of preventing the generation of a foul odor in a washing tub.

The washing equipment includes so-called household washing equipment and commercial washing equipment. Commercial washing equipment includes coin-operated laundry machines that lend washing machines, dryers, etc. to general customers, and general-purpose washing equipment that receives washing requests from customers and performs a large amount of washing and drying. .. General commercial laundry equipment is called commercial laundry equipment.
A feature of commercial laundry equipment is that it handles a large amount of laundry. Therefore, dirt such as sweat and sebum tends to remain in the washing tub. Then, this dirt becomes a nutrient and various germs propagate in the washing tub, causing a foul odor.
If the odor remains in the washing tub when the opening / closing door of the laundry device is opened, the user may feel uncomfortable and refrain from using it.
Therefore, a technique for attaching an ion generator to a washing tub has been proposed for a household washing machine.

Japanese Unexamined Patent Publication No. 2011-45619

However, the washing tubs of coin-operated laundry machines and commercial laundry machines have a larger capacity than household washing machines. In addition, since it is used by an unspecified number of people, the opening and closing doors are frequently opened and closed. Therefore, even if an ion generator is attached, there is a problem that the odor cannot be sufficiently deodorized and the odor remains.
In addition, the product life of the ion generator is shorter than that of the rotary drive unit of the laundry device. Therefore, there is a problem that the ion generator cannot be continuously operated for a long time.

A handle-type door lock 8 is provided at the edge of the slot 6. The user can open and close the opening / closing door 7 by using the handle, latch the opening / closing door 7 (empty tightening), and remove the latch.
Further, in the door lock 8, the locking / unlocking (locking and unlocking) of the opening / closing door 7 is controlled by the control unit 30 described later. That is, the control unit 30 can fix the handle in a state where the opening / closing door 7 is closed and latched. That is, the control unit 30 can lock the opening / closing door 7 by the door lock 8 and maintain the state in which the input port 6 is sealed.
On the other hand, when the control unit 30 unlocks the open / close door 7, the handle can be manually pulled to release the latch, and the open / close door 7 can be further opened to open the slot 6.
The door lock 8 is also provided with an open / close sensor 41 that detects a state in which the open / close door 7 is closed and latched. The open / close sensor 41 outputs the detection data to the control unit 30.

A water supply pipe 15 and a drainage pipe 16 are connected to the outer body 3. The outer body 3 stores the water supplied from the water supply pipe 15 and discharges the stored water from the drain pipe 16 to the outside of the laundry device 1.
The outer body 3 is provided with a water level sensor 42 that detects the water level. The water level sensor 42 outputs the detection data to the control unit 30.

A hot air supply path 20 for supplying hot air for drying and a hot air discharge path 21 are connected to the outer body 3.
A heating unit 22, an overheat prevention device, a safety device, and the like are arranged in the hot air supply path 20. The heating unit 22 is a gas burner.
A filter, a fan 23, an overheat prevention device, a check damper, and the like are arranged in the warm air discharge path 21.
When the fan 23 is rotated, the air introduced into the hot air supply path 20 is heated by the heating unit 22, and the hot air is supplied to the outer body 3. As a result, the laundry put into the drum 4 is dried. Then, the air containing moisture is introduced into the warm air discharge path 21 from the outer body 3 and discharged to the outside.

A temperature sensor 18 is arranged downstream of the warm air discharge path 21. The temperature sensor 18 measures the temperature of the air introduced from the outer body 3 into the warm air discharge path 21. Then, the temperature sensor 18 outputs the measurement data to the control unit 30.

The drum 4 is arranged so that its opening coincides with the input port 6 of the outer body 3 while separating the gap from the outer body 3. The drum 4 has a rotating shaft (not shown) extending rearward, and the rotating shaft is rotatably supported by the outer cylinder 3.

A charged fine particle generating portion 50 is connected to the top of the outer body 3. The charged fine particle generation unit 50 supplies the charged fine particles toward the inside of the outer body 3 and the drum 4.
The charged fine particles are negative ions of oxygen, positive ions of hydrogen, charged fine particle water, active oxygen and the like, and have a deodorizing effect and a bactericidal effect.
The charged fine particle generation unit 50 includes a main body 51 and a rubber hose 52.
The main body 51 has a built-in charged fine particle generation unit and a fan (both not shown).
The rubber hose 52 is connected to the main body 51 and the outer body 3, and sends charged fine particles discharged from the main body 51 toward the outer body 3. The rubber hose 52 has, for example, an inner diameter of 15 mm and a length of 500 mm. The length of the rubber hose 52 is preferably as short as possible.
The charged fine particle generation unit 50 is connected to the rear side of the outer body 3. In other words, the charged fine particle generation unit 50 is arranged at a position as far as possible from the opening / closing door 7. This is because the charged fine particles are likely to stay inside the outer body 3 and the drum 4, and the charged fine particles are less likely to leak to the outside from the opening / closing door 7.

The discharge port (the port on the outer body 3 side) of the rubber hose 52 is positioned so that the water inside becomes a vortex when the laundry device 1 operates, and even if water splashes, it is difficult for the water to reach. .. With such a position setting, even if the laundry device 1 performs normal operation, water does not hit the discharge port of the rubber hose 52. As a result, the influence of water on the charged fine particle generation portion 50 can be reduced without applying the force of water to the rubber hose 52.

Inside the housing 2, a control unit 30 that collectively controls the laundry device 1 is arranged.
The control unit (timekeeping unit) 30 is composed of, for example, a microcomputer including a CPU, ROM, RAM, and the like.
The control unit 30 executes a control for performing a laundry processing operation (washing process, drying process) on the laundry put into the drum 4 through a plurality of preset operation steps.

Further, the control unit 30 executes control to operate the charged fine particle generation unit 50 in a predetermined time zone set in advance when the laundry processing operation is not performed. The control unit 30 has a timekeeping function, and operates the charged fine particle generation unit 50 in a time zone from late at night to dawn. The predetermined time zone is specifically from 10 pm to 6 am.
The laundry device 1 is rarely used during the time period from late at night to dawn. That is, the opening / closing of the opening / closing door 7 is small. Therefore, the charged fine particles supplied from the charged fine particle generation unit 50 fill the inside of the outer body 3 and the drum 4. Therefore, it is possible to efficiently suppress the generation of bad odors in the outer body 3 and the drum 4.

[Deodorant treatment]
Next, the deodorizing treatment of the laundry device 1 will be described.
FIG. 4 is a block diagram showing a control system of the laundry device 1.
FIG. 5 is a flowchart showing the deodorizing process.

First, the control unit 30 of the laundry device 1 determines whether or not the current time belongs to a predetermined time zone set in advance (step S1). As described above, the predetermined time zone is a time zone from late night to dawn, for example, from 10 pm to 6 am.

Next, when the current time belongs to 10 pm to 6 am, it is determined whether or not the laundry processing operation is in progress (step S2).
When the laundry processing operation is not performed, the control unit 30 operates the charged fine particle generation unit 50 (step S3). That is, the charged fine particles are supplied from the charged fine particle generation unit 50 toward the outer body 3 and the drum 4.

When the laundry processing operation is performed in step S2, the control unit 30 deactivates the charged fine particle generation unit 50 (step S4). That is, the supply of charged fine particles is stopped until the laundry processing operation is completed.
The processing of steps S2 to S4 is continued until it is out of the predetermined time zone.

Then, when it is determined in step S1 that the time zone is out of the predetermined time zone, the control unit 30 deactivates the charged fine particle generation unit 50 (step S5). That is, the supply of the charged fine particles is stopped until the predetermined time zone is reached again.

As described above, when the laundry processing operation is not performed and the current time belongs to the time zone from late night to dawn, the laundry device 1 operates the charged fine particle generation unit 50. Therefore, the charged fine particles discharged from the charged fine particle generating portion 50 efficiently fill the inside of the outer body 3 and the drum 4.
When the capacity of the drum 4 is 100 L or more, it takes about one hour for the charged fine particles to fill the inside of the outer body 3 and the drum 4. Since the laundry device 1 is not used frequently during the time period from late night to dawn, the charged fine particles can be filled inside the outer body 3 and the drum 4.
Therefore, it is possible to efficiently suppress the generation of bad odors in the outer body 3 and the drum 4.

Since the laundry device 1 is intended for general customers, the customer may select the target laundry device 1 and wash the laundry even at a predetermined time zone. In this case, the charged fine particles may be reduced from the inside of the device or may disappear in some cases due to opening / closing of the door, implementation of the drying step, and the like. Even in such a case, since the supply of the charged fine particles is continued, the charged fine particles can be accumulated after the washing process is completed.
When the customer is washing, it is also possible to integrally stop the charged fine particle generation unit 50.

Since the outer body 3 and the drum 4 are horizontally arranged and the charged fine particle generating portion 50 is connected to the top of the outer body 3, the charged fine particles can be retained at the bottom of the outer body 3. Moisture tends to remain on the bottom of the outer body 3, which tends to be a source of bad odor. By retaining the charged fine particles at the bottom of the outer body 3, the generation of bad odor can be efficiently suppressed.
