Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a fully automatic washing machine with a coin switch used in a coin laundry, and particularly to a coin laundry machine equipped with a cycle for washing the no (sket and outer tub) with water. Regarding fully automatic washing machines with switches.

[Prior art]

11th M1. The prior art will be explained with reference to FIG.

FIG. 1 explains its structure, and a coin switch 2, a main circuit 3, a basket, a tray 4, a water flow generating device 5, and an outer tank 6 are housed in a body 1 as shown in the figure. The outer tank 6 is suspended from the body 1 by a support rod 11, and an electric motor M is attached to the bottom thereof with a screw 12. The shaft SH of the electric motor M drives the basket 4 or the water flow generator 5 via the clutch CR. The clutch CR operates in conjunction with the drainage pulp Mg, and when the drainage pulp Mg is operating, the basket 4 and the water flow generator 5 are connected to the shaft SH at the same time, and when the drainage pulp Mg is not operating, the clutch CR operates in conjunction with the drainage pulp Mg. connects only the water flow generator 5 to the shaft 8H.

There is a coin input lower at the top of the machine 1, and coins (not shown) inserted through the input lower are transferred to the coin switch 2.
and is stored in the coin box 8. The coin box 8 is locked to the machine body 1 by a key 9, and the coin box 8 can be pulled out from the machine body 1 only by opening and closing this.

The water supply pulp I■, the hot water supply pulp H■, and the drainage pulp Mg are respectively arranged as shown in the figure, and are used to pour water or hot water into the basket 4 and the outer tank 6, or to drain the water. The pressure switch PS1 and the lid switch LS are also as shown in the figure.The pressure switch PS converts the height of the water level in the outer tank 6 into the pressure in the pipe 13 and opens and closes the contacts as shown in Figure 2. ,
The lid switch LS is a switch whose contacts are open when the lid 14 is open and closed when the lid 14 is closed.

FIG. 3 shows the electrical connection between the coin switch 2 and the main circuit 3, FIG. 4 explains the structure of the cam switches C1 to C7 and the reversing cam CC, and FIG. 5 shows the time chart thereof. be.

Generally, in a fully automatic washing machine with a coin switch, the coin switch operates when a predetermined usage fee is input, and the main circuit 3
is connected to the power supply and operation begins. That is, in Fig. 3, when a specified number of coins are inserted into the input lower (same as the input lower in Figure 1), the relay coil RC of the coin switch 2 is energized, and the contacts R1 and R2 are closed. At this point, the hot water supply pulp HV starts operating and water injection or hot water supply begins. (In Fig. 3, the coin switch 2 is a known device and is shown schematically. Contact R3 is always a closed contact, but changes to an a contact depending on the amount of coins inserted. Fig. 3 (This mechanism has been omitted here.) On the other hand, the cam switches C1 to C7 have the structure shown in FIG.

It switches to the b contact or to neither position. Each cam switch 01-c7 and reverse cam CC
The contact state is switched according to the time chart shown in FIG. That is, when a coin is inserted, the cam switches C7 and 05 are in contact a, so the operation of the coin switch 2 connects the main circuit 3 to the power supply, and water injection or hot water supply starts as described above. When a certain amount of water is poured or hot water is supplied, the contact of the pressure switch Ps is switched from NC to NO, and the electric BJJJ machine M rotates to perform a washing cycle. Hereinafter, the cam switches C1 to C7 and the reversing cam CC are switched according to the time chart shown in FIG.
Together with the operation of the pressure switch PS, a series of cycles is completed, and finally, the cam switches C7 and C5 switch from the B contact to the A contact, thereby cutting off the power and stopping the operation.

(At this time, the contact point is the coin switch.

Since R and 2 are open, no power is supplied to the main circuit 3. ) The malfunctions of this washing machine are explained below.

In coin laundry machines, a large number of unspecified users use the machine to wash a variety of laundry items, but some of them are not just dirty, but also laundry items that have a lot of bacteria (diapers, blankets for livestock, etc.). Damn.

When a user washes a backpack (such as a rucksack), the user's shoulders are strained, and as a result, the above-mentioned bacteria may adhere to the inside of the outer tank 6 and the basket 4. Note that the adhered particles (b) multiply over time, so if washing is carried out in a washing machine in such a state, there is a fear that the laundry may become contaminated. (The number of bacteria in the outer tank 1 according to the survey) (The number of bacteria in the socket 4 is about the same as that in public baths, doors in ordinary homes, etc.) [Object of the Invention] The object of the present invention is to To provide a fully automatic washing RM machine with a coin switch and equipped with a cycle for washing away bacteria attached to a water part.

[Summary of the invention]

The present invention focuses on the fact that bacteria adhering to water-contact parts can be discharged from the body 1 by running water, and a process called sulfur washing is carried out during the washing cycle. It is designed to provide a cleaning period for parts that come in contact with water.

[Embodiment of the present invention] An embodiment of the present invention will be explained with reference to FIGS. 6 and 7. FIG. 6 shows the electrical connections. sb Compared to FIG. 3, a cam switch c s , a warning burn WL, and grain distribution to the cam switch C6 are added. FIG. 7 illustrates a time chart of the cam switches C1 to C8 and the reversing cam CC.

In this example, tub washing is performed at the beginning of the washing cycle. That is, at the same time as coins are inserted, the coin switch 2 is operated, and the timer motor TM is energized by the cam switches C2, C4, C6, and the motor M performs dewatering rotation, so that the basket 4 rotates at high speed. On the other hand, the water supply pulp ■■ or the hot water supply pulp HV is opened by the cam switch C1, and water is poured into the basket 4.

Since the basket 4 is rotating for dewatering, a part of the injected water flows upward on the inner wall of the basket 4 due to centrifugal force, and also pops out through the small hole 15 and collides with the inner wall surface of the outer tank 6. However, the particles also adhere to the outer wall surface of the basket 4 by scattering.

A portion of the injected water also flows out from between the basket 4 and the water flow generator 50. Furthermore, since the drain pulp Mg is opened by the cam switch C3, the injected water flows uniformly through the water contact area, washes away the attached bacteria, and drains the drain pulp Mg to the outside of the machine body 1. leak. In addition,
During this period, the cam switch C8 intermittently closes the a contact as shown in FIG. 7, so the warning light WL stops blinking.

The flashing warning light WL means that the tank is being washed and detergents and laundry should not be added to the tank.The user should be informed in the instruction manual, etc., and that the amount of water injected should generally be smaller than the amount of water drained. Do not exceed the water level, and continue this period for several tens of seconds to several minutes to wash the parts that come into contact with water. Since the timer motor TM is energized, when the tank washing cycle is completed, the cam switches C2, C4, C6, C8
burns out, the basket 4 stops, the warning light goes out, and water injection or hot water supply begins. Note that at this point, since C3 opens the a contact, the drain pulp Mg is closed. At this time, the user puts in detergent and detergent items. The pressure switch PS is operated by the injected water and switched to the NO contact, thereby performing a series of washing cycles in the same manner as in the prior art.

According to this embodiment, each time a wash cycle is performed,
Since the parts that come into contact with water are washed with water, it is possible to obtain a fully automatic wash with a coin switch that has a sterilization function.

〔Effect of the invention〕

According to the present invention, it is possible to add a sterilization function to a fully automatic washing machine with a coin switch.
