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.

(Explanation) Prior Art] In-type washing machines are installed in commercial laundry facilities, etc., but because they are used by an unspecified number of people, they tend to be unsanitary and are contaminated with bacteria. There are many. Additionally, coin-operated washing machines generally have a structure in which the water supply valve and drain valve do not open unless a coin is inserted, making cleaning difficult not only for the user but also for the manager.

(c) Purpose of the Invention' The present invention aims to maintain sanitary conditions by washing the washing tub with water at the start of washing Ai+, and to prevent the motor from being overloaded during washing.

(d) Structure of the Invention The present invention provides a device that starts water supply by inserting a coin, and is equipped with a manual tank washing switch that operates only within a certain time period from the start of water supply until the water level reaches the washing water level. When the switch is activated, not only the water supply valve but also the drainage force is opened, and the washing motor is also energized.

As a result, the pulsator or washing tub rotates at high speed after the coin is inserted and before washing starts, causing the water in the washing tub to be scattered.
This washes away bacteria and dirt adhering to the inside of C1K41II.

Moreover, by rotating the washing tub at t7i+ when the washing water level is reached, overload on the motor can be avoided.

(e) Example (1) is a first coin switch that temporarily switches from a normally closed contact (NC) to a normally open contact (No.) when a 100 yen coin is inserted, and (2) is a third relay coil ( 3) Relay contact (
The first relay coil is connected to the normally open contact of the first coin switch (1) through the normally closed side (NC) of 3a), and closes the relay contact (2a) when energized. While forming a holding circuit, the other relay contact (2b) is closed to energize the third relay coil (3). This third relay coil normally closes the relay contact (3a) (switches to the N side) when energized, and closes the other relay contact (3C). (4) temporarily closes when a 50 yen coin is inserted. 2nd coin switch that closes the possibility (5
) is a second relay coil connected in series with this second coin switch, which closes the relay contact (5a) in parallel with the second coin switch (4) when energized, forming a self-holding circuit, and also The contact (5b) is also closed. (6) is a price setting switch connected in parallel with this relay contact <5b), and when it is open, the price setting is 1.
50 yen or 200 yen, and 100 yen when closed. When setting the coin to 200 yen, leave the 50 yen coin slot open. (7) is an automatic return type cleansing switch that is manually closed when washing the washing and dehydrating tank.The positive characteristic thermistor (8) and the fourth relay (coil (9)) are connected in series. When the 4th relay knee 1 is energized, the relay contact 9a) is closed to form a self-holding circuit, and the other relay contact 9b is changed from the partially closed (, NC,) side to the normally open (No) side. Switching and other relay contacts (9c)
(9d) is closed.

16) is a hot water supply valve, and (17) is a washing motor. This washing/drying motor (17) is connected to the normally closed (NC) contact side of the liquid level control switch (15) via the a contact side of the fourth program contact (10d), and also connects to the normally closed (NC) contact side of the liquid level control switch (15). 10h) and the first program contact (10a
) is connected to the normally open NO) contact side of the liquid level control switch (15).

In this configuration, in order to operate this washing machine by inserting a 100 yen coin, there is a price setting switch! (6)
Close this price setting switch (6) to operate at 150 yen or 200 yen. Suppose that the price is set at 150 yen, and C1 first inserts a 100 yen coin, the 1'-
J-in switch f (1) temporarily closes to the normally open contact (NO) side, energizes the first relay coil (2), and closes the relay contact (
2a) and close the first relay coil (2) → relay contact (
2a) - Close the self-holding circuit of the seventh timer contact (10g) and close the other relay contact (2b). When the first coin switch (1) returns to the normally closed contact (NC) side after forming a self-holding circuit, the third relay coil (3
), the relay contact (3b) is closed to the (NO) side to form a self-holding circuit, and the other relay contact (3c) is closed, and at the same time, the other relay contact (3c) is normally closed. contact(
Switch from the NC) side to the normally open contact (No) side. Note that this relay contact (3a) has no meaning when the price is set to 150 yen, but it has meaning when the price is set to 200 yen.Next, when a 50 yen coin is inserted, the second = J Inch (4) is temporarily closed and the second relay coil (5)
), the relay contact (5a) is closed to form a self-holding circuit, and at the same time, the other relay contact (5b) is closed. As a result, the 7th timer contact (10g) - relay contact (5

At the same time, the water supply solenoid valve (16) is opened through the normally closed contact (NC) of the liquid level control switch (15) and the fourth timer contact (10d). It also supplies electricity and hot water. As a result, water and hot water are supplied to the washing and dehydrating tank at the same time, and the water is stored at an appropriate temperature. When the water is stored to a certain level, the liquid level control switch (15) switches to the normally open contact (No) side, and the washing motor is connected through this normally open contact (NO) - first timer contact (10a) -> reversing switch (10b). (17) is energized to perform washing, and the normally open contact of the liquid level control switch is turned ON.
The timer motor (10) is energized through 〉, and this timer motor starts rotating. From then on, the final dehydration is performed automatically according to the programming diagram. One minute after the start of operation, the 7th timer contact (TOG) Since the self-holding of the coin circuit is broken by switching from a) contact side to (b) contact side, the first, second and third relay coils (2), (5) (
3) Current will continue to flow through the device forever, and its lifespan will not be shortened. At this time, the fifth timer contact (10e) also switches, so the washing operation continues.

Before starting such a washing operation, 10 washing operations and
If you need to wash the aquarium, please wash it once after adding the fins.
By pressing the tank washing switch (7) within minutes, the 7th timer contact (10g) a contact → the normally open (No) side of the relay contact (3b) - the relay contact (2b) → Cleaning switch (7) - Positive characteristic ° - Mister (8) - Current flows through the fourth relay coil (9), the fourth relay coil (9) operates, and the relay contact (9a) closes. It forms a self-holding circuit and also connects other relay contacts (9

12), a current flows through this water supply hartz (12), and water is supplied to the washing and dewatering tank. One-sided sea contact (9c)
The drain valve (13) is also energized through the drain valve, and this drain valve opens. When the other relay contact (9d) closes, the τ-washing motor (17) is also energized, causing the motor to rotate. While the drainage force (13) is in operation, the cran knob is also operated, so the washing motor (17) becomes a dewatering motor and rotates the washing and dehydrating tub at high speed.

Therefore, the water supplied from the water supply valve (122) into the washing/spin-drying tank jumps up and down in a short time to wash away the dirt in the washing/spin-drying tank, and then passes through the water drain 113). Efforts will be made.

After about 301 liters of tank washing, the positive characteristic thermistor (8
) increases and substantially cuts off the current to the fourth relay coil (9), so the relay contact (9a) opens and ends the bath washing. When one minute has passed A after the fin is inserted, the fifth and seventh timer contacts (1 (l e ) (10g'>
is switched, water is supplied to the passage, and the washing process begins. Therefore, after one minute has passed after inserting a coin, switch on the tank washing switch (7).
Tank washing will not be performed even if you press . After 1 minute, the water level in the washing/spinner tank becomes high, and if you try to rotate the washing/spinner tank from this state, the starting load will be too large.
The start of tank washing was limited to within 1 minute before the water level in the washing and dehydrating tank reached the washing water level. This also prevents the tank from being tampered with during the washing operation.

Figure 3 shows another embodiment, with an auxiliary timer sweater (
18) is adopted. This auxiliary timer motor (18)
can be connected in parallel with the third relay coil (3), and when energized, the auxiliary timer contact (18a) connected in series with the tank washing switch (7)
) is now closed. Therefore, T: 100 yen] When the inlet is turned on, the auxiliary timer motor (18) is energized and the auxiliary timer contact (18a) is closed for 1 minute, so by pressing the tank washing switch (7) during this time, the -), cleaning is performed in the same manner as in the above embodiment.

Effects of the present invention: For example, by pressing the tank washing switch when the washing water level has not reached the washing water level one minute after inserting a coin, the water supply valve and water valve are opened while the washing motor is rotating. ``(Ko, I'm in the 111th place in the aquarium.
