Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a washing machine that displays the degree of inclination of a washing tub at the time of installation.

(Prior art) Conventionally, in a washing machine of the type in which a washing tub with a rotating tub inside is elastically suspended from an outer box, the height of the support legs is adjusted at the time of installation to adjust the inclination of the outer box, that is, the inclination of the washing tub. This prevents the washing tub from causing unbalanced vibration when the rotating tub is rotated at high speed to perform dewatering.

(WJ to be solved by the invention) However, in the past, the support legs were adjusted during installation by simply measuring the inclination of the outer box, making it difficult to accurately adjust the inclination of the washing tub. When the washing machine was rotated at high speed, there was a risk that the washing tub would cause unbalanced vibrations even if the laundry in the rotating tub was not unbalanced.

Therefore, an object of the present invention is to enable accurate inclination adjustment of the washing tub using a device that measures the position of the washing tub, and in addition, to adjust the inclination of the washing tub by a total of ∆? To provide a washing machine capable of displaying measurement results of one device with an inexpensive configuration.

[Structure of the Invention] (Means for Solving the Problems) The present invention includes a measuring device that elastically suspends a washing tub in which a rotating tub is installed inside an outer box and measures the position of the washing tub when installed. The present invention is characterized in that it is provided with a display device that can be switched to display the washing process etc. during normal operation and to display the measurement results of the above-mentioned measuring device during installation.

(Function) According to the above-mentioned means, since the degree of inclination of the washing tub can be adjusted while being measured by the meter, it is possible to accurately adjust the inclination of the washing tub, and moreover, it is possible to measure the inclination of the washing tub. Since the measurement results of the device are displayed using a display device that normally displays the washing process, etc., the device can be constructed at low cost.

(Example) An example of the present invention will be described below with reference to the drawings.

b, 14b.

On the other hand, 15 is a cover attached to the upper surface of the outer box 2, and an operation panel 16 provided at the front end of this cover has a power switch 1.
7 and "Wash", "Rinse", "Dehydration", "Water flow", "
Each setting switch 18 to 22 and a start switch/7ch 23 are provided for each setting switch 18 to 22.
, each has three LEDs 18a to 18 as display devices.
c, 19a ~ 19c, 20a ~ 20c, 21a ~
21c.

22a to 22c are provided, and display characters for each setting state are provided correspondingly.

Furthermore, the four corners of the lower part of the outer box 2 have a height of 7! Support legs 24 that can be adjusted are provided.

Although not shown, inside the cover 15 there are LEDs 18a to 18c, 19a to 19c, 2 during normal washing.
0a to 20c, 21a to 21c, and 22a to 22 (display according to the washing operation of the setting switches 18 to 22), and the total Δp of the ultrasonic sensors 13 and 14 when stationary.
A control circuit is provided for displaying the I results.

Next, the operation of the above configuration will be explained. During normal washing, when the washing time is selected with the "wash" setting switch 18 after turning on the power switch 17, one of the LEDs 18a to 18c is lit according to the selection.
When the washing time is selected with the "rinse" setting switch 19, any of the LEDs 19a to 19c is lit according to the selection, and when the dehydration time is selected with the "dehydration" setting switch 20, the LEDs 20a to 19c are lit according to the selection. 20c is turned on, and when the strength of the water flow is selected using the "Water flow" setting switch 21, one of the LEDs 21a to 21c is turned on according to the selection, and the "Course" setting switch 22 is used to select the washing course. When selected, one of the LEDs 22a to 22c is lit according to the selection. When the start switch 23 is turned on in this state, the washing operation is performed according to the washing, rinsing, spin-drying, water flow, and course conditions set by each setting switch.

Next, the operation during installation will be explained. For example, when the washing setting switch 18 and the power switch 17 are operated at the same time, the installation mode is entered. Then, the ultrasonic sensors 13 and 14 are activated, and the ultrasonic waves emitted from the ultrasonic generators 13a and 14a are reflected by the washing tub 1 and transmitted to the receivers 13b and 1.
4b, and the distance from the ultrasonic sensors 13, 14 to the washing tub 1 is measured. When the outer box 2 and the washing tub 1 are not tilted, that is, when the washing machine Ml is located at the center of the outer box 2, as shown by the two-dot chain line in FIG. 2, the ultrasonic sensor 13
and the distance from 14 to the washing tub 1 are registered in advance in a control circuit (not shown). Then, when the difference between the actual total distance g from the ultrasonic sensor 13 to the washing tub 1 and the distance is -15 mm or more, the LED 18a lights up and -1
When the distance is 5mm to -5mm, LED18b lights up and -5
When mm ~ Omm, LED] 8c lights up, 0 ~ 5m
It is set so that the LED 19a lights up when it is r11, the LED 19b lights up when it is 5 to 15 mm, and the LED I9c lights up when it is l 5 rom or more.
The LED 21a lights up when the difference between the actually measured distance 1ρ' from the ultrasonic sensor 14 to the washing tub 1 and the distance ML is -15 mm or more, and the LED 21b lights up when it is between -15 mm and -5 mm. -5mm m LED21c lights up when -Omm, and LED22 lights up when it is 0 to 5mm.
a is lit, the LED 22b is lit when the distance is 5 to 15 mm, and the LED 22C is set to be lit when the distance is 15 mm or more. Therefore, each LED 18a to 18c
, 19a to 19c and 21a to 21. c, 22a
Adjust the height of each support leg 24 while visually checking the display of ~22c, and connect LED18C or 19a and LED21c.
Alternatively, when 22a is turned on, the outer box 2 and the washing tub 1 are placed in a state where there is no inclination, that is, the washing tub 1 is placed in the center of the outer box 2.

In this way, in this example, instead of adjusting the height of the support leg 24 by simply checking the inclination of the outer box 2 as in the conventional case, the height of the support leg 24 is adjusted using the ultrasonic sensors 13 and 14. A display device whose display state changes based on the distance between the outer box 2 and the washing tub 1, that is, LEDs 18a to 18c, 19a to 1
9c, 21a to 21. c.

Since the height of the support leg 24 is adjusted while looking at the displays 228 to 22 (), the inclination of the washing tub 1 can be adjusted much more accurately than before, and the washing tub 1 prevents unbalanced vibrations during spin-drying. This is surely prevented from occurring.

In addition, in the above-mentioned embodiment, the "washing" time was set to LE of 30η.
Although this is done using D13a to 18c, it may also be displayed digitally. In this case, the distance calculated by the ultrasonic sensor 13 can also be displayed digitally. It can be implemented with appropriate modifications without departing from the above.

[Effects of the Invention] As is clear from the above description, the present invention elastically suspends a washing tub in which a rotating tub is installed inside an outer box, and measures the position of the washing tub at the time of installation. equipment,
During normal operation, the washing process is displayed, and during installation, the 51A shown above is displayed.
Since the device is characterized by being equipped with a display device that can be switched to display the total/1111 result of the P1 device, it is possible to accurately adjust the degree of inclination of the washing tub while using the 51All+ device on the ~1 side. Moreover, since the display of the total 11 results of the total 1111J apparatus uses a display device that normally displays the washing process, etc., it has the excellent effect of being able to be constructed at low cost.
