Description

TECHNICAL FIELD The present invention relates to a washing machine.

(B) Conventional technology As a conventional example, the coin-type washing machine disclosed in Japanese Examined Patent Publication No. 63-24720 (D06F33 / 02) has a four-digit display device. The amount of money input is displayed, and the remaining time is displayed during operation.

(C) Problems to be Solved by the Invention In a coin-type washing machine such as the conventional example, a dip switch for adjusting the set price is built in the operation section. It was very troublesome to dismantle the operation part when checking the condition.

On the other hand, if the DIP switch is arranged at an easy-to-operate location, there is a danger that a third party may change the set price.

In view of such a problem, the present invention aims to simplify the number of inspection steps in a washing machine.

(D) Means for Solving the Problem Means of the present invention for solving the above-mentioned problems are achieved by operating the operation section provided on the upper part of the machine frame, and by mounting the operation section inside the operation section and removing the wall surface of the operation section. Specification switch for changing the specifications of the washing machine, such as setting the amount of money required to operate the washing machine by its operation, and inputting the amount of money corresponding to the set amount by the specification switch when operating the washing machine A detection switch for detecting the presence or absence of a set amount, a control means for controlling the operation based on the setting specification by the specification switch when the input of the set amount is detected by the detection switch, the specification of the washing machine such as the set amount, and the remaining operation. A display unit that displays the operating status of the washing machine, such as time, and that indicates that the power is turned on when the power is turned on, and a display unit that is disposed on the operation unit and that does not remove the wall surface of the operation unit and that operates individually. A plurality of operable input switches, the control means specifies a specific operation detection unit that detects a specific switch operation input that operates the plurality of input switches at the same time, and the specific operation detection unit. When a switch operation input is detected, the display unit includes a display changing unit that changes the display at power-on to the display of the specification of the washing machine such as the set amount of money.

(E) Operation That is, when the user performs a specific operation on the input switch, the specific operation detection unit detects the operation and the display change unit displays the content set by the specification switch on the display unit. After confirming the display content, the user can operate the input switch again to return the display on the display unit to the display before the change.

The display on the display unit (5) can be returned to the initial state.

Further, (34) to (38) are ON / OFF switching type DIP switches, which are used for determining the specifications of the washing machine at the manufacturing stage and for changing the specifications by an administrator. That is,
The DIP switches (34) (35) (36) are for determining (changing) the set price, and the set price according to the set state is predetermined as shown in the table below, and the microcomputer (10)
Immediately after turning on the power, this DIP switch (34) (35)
The signal from (36) is discriminated, and the RAM (1
2) Remember in. Further, the dip switch (37) is for washing the necessity of supplying hot water, and the dip switch (38) is for washing the necessity of introducing detergent.

The clear switch (33) and the dip switches (34) to (38) are arranged on the base in the operation section (2), and are used to switch the dip switches (34) to (38). Is the front panel (2a) of the operating section (2)
The clear switch (33) is removed, and a tool such as a screwdriver is inserted through a small hole (not shown) provided on the back surface of the operation section (2) to operate the clear switch (33).

The tank cleaning switch (32) and the clear switch (3
3) is equivalent to the input switch, DIP switch (34)
(38) to (38) correspond to specification switches for setting the washing operation by instructing price setting and whether hot water supply or detergent is required.

Further, since the microcomputer 10 performs the operation of FIG. 1 as described later, the specific operation detecting section ((S-1) to (S-4) and (S-8) for detecting a specific operation of the input switch is performed. Is equivalent)
And a display change unit (corresponding to (S-5) and (S-9)) for changing the display content of the display unit 5 to the content set by the specification switch, and the display content of the display unit 5 before the change. And a re-display unit (corresponding to (S-12)) for returning to the display.

The operation of such a configuration will be described with reference to FIGS. 1 and 5.

Here, “mode 1” in FIG. 1 means that the display mode of the display unit (5) displays the amount of money to be inserted or the remaining time, and similarly, “mode 2” means the dip switch (34). ) (35) (36) that displays the setting status,
And "mode 3" means the dip switches (37) (3
Indicates that the setting status of 8) is displayed.

First, immediately after the power is turned on, the "mode 1" is automatically set, and the display section (5) displays a value according to the amount of money put. During operation, the last 2 digits of the program are displayed.

Now, in the coin-type washing machine as in this embodiment, it is necessary to confirm the set price and other specifications before factory shipment.

Therefore, in the present embodiment, after the power is turned on, the display mode is switched from "mode 1" to "mode 2" by turning on the clear switch (33) and the tank cleaning switch (32) simultaneously for 5 seconds continuously. (S-1) to (S-5) (in this case, the tank cleaning operation is not executed). In this "mode 2", the setting state of the dip switch (34) is set to the hundreds digit of the display section (5) and the dip switch (3) is set.
The setting state of 5) is displayed on the tens position of the display unit (5), and the setting state of the dip switch (36) is displayed on the ones position of the display unit (5) (S-6). For example, if the dip switch is off (-) and when it is on (o), the set price of 350 yen is as shown in Fig. 5 (a). At the same time, the LED (7) (8) is blinked to notify that the display mode is 2 (S-7).

Further, it is possible to switch from "mode 2" to "mode 3" by turning on the bath cleaning switch (32) (S-8) (S-9) (in this case, the bath cleaning operation is not executed. ), In this "mode 3", the dip switch (3
The setting state of 7) is displayed in the hundreds position of the display unit (5), and the setting state of the dip switch (38) is displayed in the tens position of the display unit (5) (S-10). For example, DIP switch (37) ON (hot water required), DIP switch (38) OFF
In (Detergent not inserted), the display is as shown in FIG. At the same time, it is informed that the display mode is 3 by blinking the LEDs (6) and (8) (S-1
1). The "mode 3" can be switched to the "mode 2" by turning on the tank cleaning switch (32) again.

Further, in order to return to the "mode 1", the clear switch (33) may be operated (S-12).

As described above, in this embodiment, since the setting states of the DIP switches (34) to (38) on the substrate can be displayed on the display section (5), it is necessary to take out the whole panel (2a) for confirmation. Absent.

Incidentally, in the present embodiment, the display of the set price in the "mode 2" may be directly displayed by the numeral as shown in FIG.

Further, although the embodiment is a coin-type washing machine, it may be a home-use washing machine, switching between different programs, 50Hz-60H
Use the specification change switch to change z.

(G) Effect of the Invention In the washing machine of the present invention, since the state of specifications can be easily confirmed, the number of inspection steps can be simplified.
