Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a washing machine, and particularly to an improvement of a coin control device in a so-called coin-operated washing machine, which is operated by inserting a coin.

(Prior Art) In general, this type of washing machine is provided with a top plate 2 at the top of a washing machine main body 1 as shown in FIG. 1, and various control devices (not shown) are installed behind the top plate 2. A housing operation box 3 is arranged, and a panel 4 is provided to cover the open surface of the operation box 3. A coin control device 6 that is rotatable around the fulcrum portion 5 is disposed in a partially cut out portion of the panel 4. 7
Reference numeral 8 indicates an input slot provided in the coin control device 6, and 8 indicates a key, and a coin sorting mechanism, a coin box (not shown), etc. are provided inside the coin control device 6 housed in the operation box 3. Furthermore, a coin box 10 for collecting coins is provided in the lower space 9 of the coin control device 6.

When collecting coins stored in the coin box 10 of the coin control device 6,
First, the key 8 is turned in the direction of arrow P to remove the key, and the entire coin control device 6 is rotated in the direction of arrow Q. Then, as shown in the figure, insert your hand and take out and collect the coin box 10.

(Problems to be solved by the invention) For example, coin-operated washing machines as described above are disclosed in Japanese Utility Model Application Publication No. 54-96298 and Japanese Utility Model Application Publication No. 56
There have been many proposals such as Publication No. 145493, but in all of these, the coin box 10 is simply installed in the lower space 9 of the operation box 3.
No consideration was given to the support structure or vibration isolation structure. Therefore, the coin box 10 cannot be held securely, and the coin box 10 rattles or dances due to vibrations caused by the washing machine main body 1 during dewatering or other external forces, causing discomfort to the user, and the coin box 10 is not stored inside the washing machine. There was a problem where coins that had been placed would spill outside. Furthermore, when the coin box 10 is set again after the coins have been collected, the coins are simply installed in the lower space 9 of the operation box 3, and since there is no reliable positioning, the coins may remain on the surroundings and be incompletely set. Therefore, there was a risk that the coins would not be placed in the coin box 10 reliably.

In view of these conventional problems, the present invention aims to provide a washing machine that can securely hold a coin box and that can be easily and reliably attached and detached.

(Means for Solving the Problems) In order to achieve this objective, the present invention covers the open surface of the operation box integrally formed on the upper part of the washing machine body with a panel having an opening, and operates the operation box from the opening. In a washing machine in which a coin control device having a coin sorting mechanism and a coin box is housed in a box, the coin box of the coin control device is removably housed in a cover having a drawer opening. A convex portion elastically protruding inward from the side wall surface where the coin box is located is integrally formed, and a concave portion corresponding to the convex portion is provided on the side of the coin box, a guide groove for guiding insertion of the convex portion, and A locking stepped portion is formed to lock the upward movement of the convex portion.

(Function) According to the above configuration, when the coin box is pushed into the cover to accommodate the coin box at the set position in the cover, the protrusion on the cover side fits into the guide groove on the coin box side. This guides the insertion of the coin box, and the coin box is reliably positioned at the set position inside the cover by the fitting between the protrusion and the recess and the engagement between the protrusion and the locking step. At the same time, the protrusion and upward movement from within the cover are restricted.

(Example) Hereinafter, an example of the present invention will be described based on FIGS. 2 to 5.

In the figure, 12 is a washing machine main body, on which a top plate 13 is provided, and an operation box 14 is integrally formed at the rear thereof. Inside the operation box 14, various control devices (not shown) are arranged to control each load such as a motor to execute washing, rinsing, and dehydration processes, and a fully open part of the operation box 14 is provided. A panel 15 is provided.

16 is a coin control device, which includes an input slot 17, a coin sorting mechanism 18, and a coin box 19;
It is housed in the operation box 14. The coin sorting mechanism 18 and the coin box 19 are covered with a cover 20 made of a box-shaped metal plate having a withdrawal port 28 on the front side of the input port 17, and the coin box 19 can be inserted into and removed from the cover 20. This cover 20 is fixed to the coin control device 16.

As shown in FIG. 5, a protrusion 29 that elastically protrudes inward is integrally formed near the lower end of the side wall of the cover 20 where the coin box 19 is located, and both side walls of the coin box 19 includes a recess 30 corresponding to the protrusion 29, a guide groove 31 for guiding the insertion of the protrusion 29, and the protrusion 29.
A locking portion 32 is formed to lock the upward movement, and when the coin box 19 is housed in the set position in the cover 20, the convex portion 29 locks into the guide groove 31.
In this setting position, the protrusion 29 elastically fits into the recess 30 and the protrusion 29 engages with the locking step. 32.

The coin control device 16 is disposed corresponding to the opening 15a of the panel 15, and is placed in a lowered position (see FIGS. 2 and 3) within a storage space surrounded by the operation box 14 and the panel 15. (see figure) and a raised position protruding upward from panel 15 (see figure 4)
The key 21 is arranged so that it can be raised and lowered between the
The panel 15 is configured to be lockable by a lever 22.

Furthermore, the coin box 19 is located in the opening 15 of the panel 15 when the coin control device 16 is in the raised position.
a, and is arranged so as to retract into the lower space 23 in the operation box 14 in the lowered position, and
A spring receiving portion 24 is provided on the bottom surface of the lower space 23 of the operation box 14, and a coil spring 25 as a resilient body is attached to the spring receiving portion 24. It is fitted onto the spring receiving portion 26 to urge the coin control device 16 upward.

In the above-described configuration, when a coin 27 is inserted through the coin slot 17, it enters the coin sorting mechanism 18 as shown by the arrow S, passes through a predetermined amount, falls into the coin box 19 as shown by the arrow T, and is accumulated there. When the coin 27 passes, a coin switch is turned on, and in response to the signal, power is supplied to various control devices and loads in the operation box 14 for a certain period of time, and washing, rinsing, and dehydration processes are automatically performed. .

At this time, the coin box 19 is elastically held from both sides by the convex portion 29 of the cover 20, and the convex portion 29 is connected to the locking step portion 32 on the cover 20 side.
This will ensure that the coin box 19 is held securely, and will prevent the coin box 19 from dancing or the coins inside spilling out due to vibrations during spin-drying of the washing machine. There's nothing to do.

On the other hand, there are 27 coins in the coin box 19.
When the amount accumulates to a certain extent, when the key 21 is turned in the direction of arrow P to unlock the coin as shown in FIG.
When the coin box 19 is pulled in the direction of arrow R from the drawer opening 28 on the front surface of the cover 20 in this raised position, the protrusion 29 is displaced outwardly and passes over the recess 30, and the coin box 19 is pulled out. When coins are collected from the coin box 19 in this way, the coin box 19 is pushed into the cover 20 again and inserted, but at this time the protrusion 29
fits into the guide groove 31 on the coin box 19 side,
It guides the insertion of the coin box 19, and the coin box 19 is accommodated in the installation position within the cover 20, and in this setting position, the protrusion 2
9 fits into the recess 30, and its positioning is performed reliably, and the protrusion 29 engages with the locking step 32 on the coin box 19 side, so that its upward movement is reliably regulated. In this way, Coin Box 1
When the installation of the coin control device 9 is completed, the coin control device 16 is held down from above and locked with the key 21, thereby completing coin collection.

(Effect of the invention) According to the washing machine of the invention, as is clear from the above explanation, the convex part that elastically projects inward from the side wall surface of the cover fits into the convex part on the coin box side. This guides the insertion of the coin box into the set position inside the cover, which allows the insertion of the coin box to be carried out extremely smoothly, and also allows the coin box to be elastically held from both sides by the protrusion on the cover side. , and the convex portion on the cover side engages with the locking stepped portion on the coin box side,
Since the coin box is securely held, the coin box will not rattle or dance, or the coins will not spill out due to vibrations during dehydration, and the coin box will not fit inside the cover. The fitting of the convex portion and the concave portion and the engagement of the convex portion and the locking stepped portion ensure that the housing is placed in the set position of The coins will be stored reliably without any problems.

Furthermore, since coins do not fall from the coin box into the operation box as described above, there is no adverse effect on the various control devices within the operation box.
