Description

DETAILED DESCRIPTION OF THE INVENTION [Technical field to which the invention pertains] The present invention relates to a washing machine that can check the operation of each manual function and output function.

(Prior art and its problems) Self-operating washing machines operate by automatically changing processes such as washing, washing, and dehydration in a preset order and time. However, the program timers for these 42 washing machines include mechanical timers incorporating a cam and contact mechanism, and electronically controlled timers incorporating a microcomputer.

Among these, the electronically controlled type is stored in a control device (1) in which the order and times of processes such as washing, rinsing, and dehydration are set and stored, as shown in Fig. 2. Rinse and dewatering course start switch (3), change the motor operation time and valve opening/closing of the standard course as appropriate, e.g. "Wash", "Rinse number", "Dehydration" select switch (4) (5) (6) In addition, there is a changeover switch (7) for checking operation, a water level switch (8) that switches the electric circuit when the water level in the washing tub reaches the specified water level, or when the water level drops after draining water, and a lid that closes during spin-drying. There is a lid switch (9) that cuts off the power to the motor (11) when the laundry is opened or an extreme imbalance occurs during spin-drying, and an unbalance switch (10) that detects when the laundry is shifted to one side during spin-drying.
) is introduced.

In addition, a forward/reverse rotation motor for driving is used as an output part (] 1
), a solenoid that operates the drain valve (12), a water supply valve (13) that supplies the required amount of tap water into the tank, l
For example, a light emitting diode (

) or select switch (4) (5) (6) as necessary.
When the switch is closed, the output signals from these switches (3) to (6) enter the control device (1), where the washing course is set, and the water level switch (8), lid switch (9), and unbalance switch are activated. (10) to the output signal from the control device (1) to the motor (
11), solenoid)' (12), enters the water supply valve 43),
Operation control is performed to automatically switch the water supply, washing, drainage, draining, and dewatering processes to a set course. At the same time, each process currently in progress is indicated by an indicator light (
17), (18), and (19) are displayed in sequence.

By the way, when checking the functions of the input section and output section for repair, inspection, function check during manufacturing, etc., close the operation check changeover switch (7) and switch to the test operation process to check the input/output function. In such a case, the conventional method is to shorten the time of each process by using the same input/output mode as the energization operation described above, or to turn each process on and off in an appropriate order for an appropriate time. The input/output functions are checked.

However, if this method does not operate normally, it may not be possible to determine whether the input function or output function is defective, and in such cases it is necessary to check the input function and output function individually again. As a result, confirmation takes time and the confirmation process becomes complicated, which may lead to errors in judgment.

(Object 1 of the Invention) Object 1 of the present invention is to eliminate the disadvantages of the conventional example, and to easily and accurately check input/output functions for repairs and inspections without complicating the configuration of the control device. Each one has a washing machine provided.

[Key points of the invention]

However, according to the present invention, the purpose of the lever is to provide a manual switchable manual section for test operations in a washer d1 machine having a control device that presets the sequence and time of steps such as washing, washing, dewatering, etc. , a + stage which is formed in the control device and outputs to each device regardless of the washing 111 operation operation, and a + stage which receives the output from the control device (operates at This is achieved by having an output section.

(Example of the invention) Embodiments of the present invention will be described in detail below with reference to the drawings.
