Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a coin-operated washing machine that allows washing of the washing tub prior to washing.

←) Conventional technology] In-type transportation machine 1-1 Coin-operated laundromat IJ- for commercial use
However, because they are used by unspecified people, they tend to be unsanitary and are often contaminated with bacteria. Therefore, it would be fine as long as a manager is always making efforts to clean the laundry, but there are coin laundries without a manager, which is often undesirable from a sanitary standpoint.

(c) Purpose of the Invention The object of the present invention is to provide a coin-operated washing machine with a tank washing switch so that the washing tub can be sterilized or washed with water before starting washing, thereby maintaining sanitary conditions.

2) Structure and operation The present invention connects a tank washing switch in series with a relay contact that closes when a coin is inserted, a tank washing relay, and a timer contact, and when a specified amount of coins are inserted and the above-mentioned switch is pressed. , the water supply valve, drain valve, and washing and dewatering motor are energized at the same time. As a result, when the galvanometer switch is pressed, water is supplied to the rotating washing tub, and the liquid immediately splashes and washes the entire tub before being discharged.

(j→Example Below, the example will be explained based on the diagram. +1) is the coin switch that temporarily closes the contact when a coin is inserted, (2
) is a coin relay connected in series with this coin switch, and when it is energized, the first contact (2a) and (2b) are closed. (3) is the tank washing switch that you press when washing the washing tub;
(4) is a relay connected in series with this tank washing switch, and when the relay is powered up, the relay contact (4a) in parallel with the switch (3) is closed to form a self-holding circuit; Other relay contacts (4/b) (4
c) (4d) (4e) (4f) are closed and the other relay contact (4g) is opened. (5) is a short time timer motor, which opens a timer contact (5a) connected in series with the above-mentioned relay (4) when a certain period of time has elapsed after energization. (6) A washing start switch connected in series with the IF relay contact (2b) that closes when a coin is inserted, and (7) a relay coil connected in series with this switch. is closed to form a self-holding circuit, and at the same time, the relay (4)
) etc. to open the relay contact (7b) in series. (8) is a timer motor for advance operation, with 7 timer contacts C8a) CBb) CBc) (8d) (8e) (
8f) (8g), and the opening and closing states of the lower half are shown in the programming diagram in FIG. (9) is a safety switch that opens the contact when the top lid is opened, (lO) is a travel indicator lamp that lights up during washing operation, and (11) is a washing table inch that lights up during washing tank operation. When a certain amount of water is stored in the tank, the normally closed contact (NC) changes to the normally open contact CN.
0) K switching device (16) is a washing and dewatering motor, which is connected in series with a reversing switch (+7).

The above configuration is used and its operation will be explained below. When a predetermined amount of coins is inserted, the coin switch (1) is temporarily turned off, energizes the fin 1/-+2+, and the relay contact (2) is turned on.
a) closes to form a self-retaining port 11&. When the washing start switch (6) is pressed in this state, the relay coil (7) is energized, the relay contact (7a) is closed, and a self-holding circuit is formed. At the same time, the seventh timer contact (8g) and the first contact 12, washing tub Supply water inside. When the water is supplied to a predetermined level, the liquid level control switch (15) switches to the normally open contact (NO) side and the cleaning/dehydration motor (16) is operated automatically according to the programming diagram. Continued.

If you want to disinfect the washing tub before starting the washing operation, press the tub washing switch (3) after inserting a coin.

This allows the 7th timer contact (8g) and relay contact (2b
)' (7b), tank washing switch, (3), tank washing relay (4), timer, and current flows through contact (5a), and tank washing relay (4) closes relay contact (4'a) and self-energizes. A holding circuit is formed and the timer motor (5) is energized for a short time. - Connect the relay by energizing the tank washing relay (4)! (4b) (4c) (4d) (4e) (4
f) is closed, relay contact (4f) and safety switch (9)
・Power is applied to the water supply solenoid valve θ through the liquid level control switch (normally closed contact (NC) of I) and the 6th timer contact (8f), and at the same time water is supplied to the washing tub, the relay contact (4c)
(4d), the disinfectant solution solenoid valve is energized, and the disinfectant solution is also supplied. Also, at the same time as the draining solenoid valve UK is energized through the relay contact (4C), the washing and dewatering motor is also energized through the relay contact (4e).

When the draining electromagnetic valve a is energized, the draining valve is opened and the clutch is operated at the same time, so that the washing and dewatering motor end rotates the washing tub. At the same time, the relay contact (4b) closes and the tank washing indicator lamp (■) lights up.

As a result, water and disinfectant are supplied into the washing tub, which is rotating at high speed, so the water and disinfectant immediately scatter and disinfect the entire washing tub, and the disinfected solution is drained from the drain valve. be done. After washing the tank for a certain period of time in this way, the timer contact (5a) is cut off by the short timer (6).
Since the power to the tank washing relay (4) will be cut off, please connect the relay A.
Open (4a), (4b), (4c), (4d), (4e), and (4f) to complete the galvanometer flow. Then wash start switch (6
), the washing operation is performed as described above.

Also, when the washing start switch (6) is pressed during tank washing, the relay coil (7) is energized, the relay contact (7b) is opened, and the energization to the tank washing ring (4) is cut off. It is interrupted and the washing operation starts.

(f) Effects As described above, in the present invention, water is supplied and drained at the same time as the washing tub is rotated by turning on the galvanometer switch (3), so that the water supplied to the washing tub is immediately scattered. The entire cleaning tank can be washed, and sterilization can also be performed by supplying disinfectant at the same time. Furthermore, since the galvanic switch (3) is connected in series with the relay contact (2b) which closes when a coin is inserted, neither water nor disinfectant will be supplied unless a coin is inserted. There is no need to insert coins into the water supply system, and even when electricity is installed in a coin laundry, management is easy.
