  Further, when the power switch 18f is turned on in FIG. 3, if the other switch (washing time setting switch 18a) has been pressed in advance, the control means 17 causes the installation work when the washing machine is purchased. A special operation mode for determining whether or not the washing machine has been installed correctly and a special operation mode for product inspection in a factory are set.

  The special operation mode for checking the installation state is, for example, whether tap water is supplied to the water supply valve 12 from a water tap (the water tap and the water supply valve 12 are correctly connected via a water supply hose). In the operation to confirm whether the drain valve 11 is properly drained via the drain hose, etc. This is a special operation mode that is performed when a washing machine is purchased and installed.

  The present application provides an operation mode in which the inclination of the washing machine body is confirmed by detecting and displaying the inclination of the installed washing machine body in the special operation mode.

  The operation of the above configuration will be described with reference to the operation flowchart of FIG.

  The operation starts at step 60 in FIG. 5, and the power-on switch 18g is turned on at step 61. At this time, if the washing switch (washing time setting switch) 18a is previously turned on at step 62, the process goes to step 63. Proceed to set the operation mode for installation confirmation.

  The operation mode for checking the installation is to check whether tap water is supplied from the tap to the water supply valve 12, and the drain valve 11 can be drained correctly through the drain hose. This is a special operation mode that is performed when a washing machine is purchased and installed for the first time.

  As an operation, the water supply valve 12 is driven by the control means 17 for a predetermined time (for example, 1 minute) to supply washing water into the water receiving tub 3, and at this time, the water level in the water receiving tub 3 is detected (water level detection). The means is not shown), and it is determined whether the water has been supplied correctly depending on whether or not the predetermined water level has been reached.

  Further, after the water supply, all the operations are suspended for a predetermined time (for example, 1 minute), and it is detected whether the water level in the water receiving tank 3 has changed. This purpose is an operation for detecting whether or not water leakage has occurred for some reason. If the water level is lowered, it can be determined that water leakage has occurred.

  Then, the drain valve 11 is driven by the control means 17 to drain the washing water in the water receiving tub 3 out of the washing machine main body. After a predetermined time (for example, 3 minutes), it is determined whether there is no problem in the drainage path based on whether all the washing water is drained outside the machine.

  In addition to the operation modes as described above, an operation mode for detecting whether the washing machine body 9 is tilted with respect to the floor surface is provided, and the X-axis / Y-axis / Z-axis acceleration detected by the acceleration detection means 15 is provided. The inclination is detected from the value.

  If it is determined in step 62 that the washing switch has not been pressed, the routine proceeds to step 71 and a normal washing operation is performed.

  After step 63, in step 64, it is set which operation in the operation mode for installation confirmation is performed. For example, the special operation mode to be selected is selected by pressing the rinse number setting switch 18b. Next, in step 65, the start / pause switch 18e is pressed to start the operation in the selected operation mode.

  If it is determined in step 66 that the operation mode for confirming the inclination of the washing machine body has been selected, the process proceeds to step 67 and the subsequent operations are performed. If it is determined in step 66 that the other operation mode has been selected, the process proceeds to step 72 to perform the water supply confirmation operation and the drainage confirmation operation as described above.

  In the operation mode for checking whether the washing machine main body is installed horizontally, in step 67, the acceleration data g1x, g1y, g1z detected by the acceleration detection means 15 is input to the control means 17. In step 68, the inclination of the washing machine body is detected from the acceleration data.

As described above, when the washing machine main body is installed horizontally with respect to the ground (that is, the floor surface), the X-axis, Y-axis, and Z-axis act as shown in FIG. Each of the three axes of acceleration is detected. Since gravitational acceleration 9.8 m / s ² works in the vertical direction, when the rotating drum 1 is tilted by 20 °, it is 9.8 × cos 20 ° m / s ^{2 in} the Z-axis direction. An acceleration of 9.8 × sin 20 ° m / s ² works in the acceleration and the X-axis direction. Since the Y axis is perpendicular to the gravitational acceleration, the acceleration is zero.

  When the washing machine body is installed tilted in the front-rear direction and the left-right direction with respect to the ground (that is, the floor surface), accelerations different from those described above are applied to each of the three axes. Can do.

  As shown in FIG. 12, for example, the angle is α ° in the front-rear direction (when the front side is higher than the back side and is inclined by α °), and further β ° in the left-right direction (the right side is the left side when viewed from the front side) The detected accelerations in the X axis, Y axis, and Z axis directions are gx1, gy1, and gz1, respectively.

  Here, the relationship of Formula 1 holds in the front-rear direction (X-axis, Z-axis), and Formula 2 holds in the left-right direction (Y-axis).

  Since the accelerations gx1, gy1, and gz1 detected by the acceleration detecting means 15 are known, the longitudinal inclination α ° and the lateral inclination β ° of the washing machine main body can be obtained by Expression 1 and Expression 2.

  In step 69, the detected degree of inclination is displayed on the display means 19 for a predetermined time, for example, for one minute, to inform the installer or user, and then the operation proceeds to step 70 to end the operation mode for installation confirmation.

  As a display example of the inclination of the washing machine main body in step 69, the operation will be described with reference to the detailed display diagram of FIG.

  For example, by using the first and second digit segments of the number display portion 19f, the two segments are turned on to indicate which part of the front, rear, left and right of the washing machine body is lowered. indicate. When the front right part is lowered, 1c and 1d are turned on, and when the rear left part is lowered, 2a and 2f are turned on.

  The degree of further lowering, that is, the angle of inclination is represented by lighting of each segment of the washing time display unit 19a. For example, when the tilt angle is 0.25 degrees, only 19a-1 is lit, and when it is 0.5 degrees, 19a-1 and 19a-2 are lit, etc. The number of segments to be lit is increased.

  In the above-described display example of the inclination degree, the number of lighting segments of the washing time display unit 19a is changed according to the detected angle. However, the present invention is not limited to this. When the tilt angle is large, the blink cycle is fast, for example, 0.2 second lighting and 0.2 second turn off are repeated, and when the tilt angle is small, the blink cycle is slowed. For example, by repeatedly changing the blinking cycle of the lighting segment indicating the tilt direction of the washing machine body so as to be inversely proportional to the detected tilt angle, such as 0.5 second lighting and 0.5 second lighting off. Also good. Moreover, it is also possible to display the raised part of the washing machine main body 9 on the time display unit 19a.

  As described above, in the first embodiment, the control means 17 allows the input setting means 18 to set a special operation for confirming the inclination of the installed washing machine body, and the input setting means 18. If the special driving operation is set by the above, the installer or the user can detect the inclination of the installed washing machine main body 9 based on the detected values of the three axes or the axes detected by the acceleration detecting means 15. The display means 19 can notify the degree of inclination of the installation floor surface, and can prompt the user to adjust the inclination of the washing machine. As a result, the washing machine can be operated while being level with respect to the floor surface, so that vibration and noise during dehydration can be reduced.

Other configurations are the same as those of the first embodiment, and detailed description thereof is omitted.

  The operation of the above configuration will be described. When it is determined that the operation mode for checking the inclination of the washing machine body has been selected, the control means detects the inclination of the washing machine body from the detected acceleration data, and displays the detected inclination on the display means 19 for a certain period of time. The buzzer sound of the buzzer notification means is intermittently blown so as to be inversely proportional to the tilt angle. When the tilt angle is large, the sounding cycle is shortened, for example, 0.2 second on / 0.2 second off is repeated, and when the tilt angle is small, the sounding cycle is delayed, for example, 0.5 second on / 0. As shown in .5, it sounds in inverse proportion to the detected tilt angle. In addition, it is also possible to change a buzzer sounding period so that it may be proportional to an inclination angle.

  As mentioned above, in this Embodiment 2, it was set as the special operation operation for checking the inclination of the installed washing machine by setting it as the structure provided with the buzzer alerting means 31 which reports by a buzzer. Occasionally, the inclination of the main body of the washing machine installed is detected from the detected values of the three axes or two axes detected by the acceleration detecting means 15 and is notified by the display means 19 and / or the buzzer notifying means 31.

Other configurations are the same as those of the first embodiment, and detailed description thereof is omitted.

  The operation of the above configuration will be described. When it is determined that the operation mode for confirming the inclination of the washing machine body has been selected, the control means detects the inclination of the washing machine body from the detected acceleration data, and the detected part of the washing machine body 9 is lowered, The inclining angle is notified by voice notification means. For example, a notification such as “the right side of the front surface of the main body is lowered by 0.5 degrees. Turn the screw of the height adjustment leg of the right front surface to adjust so that the right side of the front surface of the main body is raised.” Note that the notification content by voice is not limited to the present embodiment, and may be any form that allows the installer or user to correct the inclination of the washing machine.

  As mentioned above, in this Embodiment 3, it was set as the special driving | operation operation | movement for confirming the inclination of the installed washing machine by setting it as the structure provided with the audio | voice alerting | reporting means 32 which alert | reports by an audio | voice. Occasionally, the inclination of the main body of the washing machine installed is detected from the detected values of the three axes or two axes detected by the acceleration detection means 15 and is notified by the display means 19 and / or the voice notification means 32. By informing the user's hearing, the inclination of the washing machine body 9 can be notified more specifically and easily.

(Embodiment 4)

  In the inspection process of the factory, a place where the floor surface is horizontal on the ground is created, and X-axis / Y-axis / Z-axis data detected by the acceleration detecting means 15 is stored in the storage means 30 at this place.

  Since the floor surface is horizontal, the washing machine body 9 is also placed horizontally, and the X axis, Y axis, and Z axis detection data detected by the acceleration detection means 15 is also detected in the horizontal state as described above. Should be the typical detection data.

  However, in reality, there may be cases where the data is not ideal due to variations in the body of the acceleration detection means 15 and the accuracy of attachment to the water receiving tank 3. In order to offset this difference in data, data to be detected when placed horizontally is stored, and when this data is detected, if it is in a horizontal state, the above-described variation factor is canceled. be able to.

  That is, when the allowable range angle is ± 1 °, it is assumed that the washing machine is installed horizontally when the relationship of Expression 3 is established in the front-rear direction and Expression 4 is established in the left-right direction.

  If Formula 3 and Formula 4 satisfy both the front-rear direction and the left-right direction within the allowable angle (YES), it is determined that there is no problem and the operation proceeds to step 91 to end the operation mode for installation confirmation. If either one of the left and right directions is out of the allowable range, it is determined that the apparatus is not installed in a horizontal state. In step 90, the detected inclination of the washing machine main body is displayed on the display means 19 or the like to The operation is terminated in step 91.

  As described above, in the fourth embodiment, the control means 17 places the washing machine horizontally with respect to the ground in the inspection process after the washing machine is manufactured in the factory, and at this time, the acceleration detection means 15 detects. The detection value of the three or two axes is stored in the storage means, and the acceleration value is detected when the stored value and the input setting means 18 are set to a special driving operation for confirming the inclination of the installed washing machine. By comparing the detected values of the three or two axes detected by the means 15 and detecting the inclination of the installed washing machine main body, the detection variation in the manufacturing stage of the acceleration detecting means 15 main body is corrected.

  At this time, if it is understood that, for example, a rotation of 1 ° can be changed by turning one rotation, the reference inclination αf ° in the front-rear direction, the reference inclination βf ° in the left-right direction, the inclination α3 ° in the front-rear direction, From the value of the inclination β3 ° in the left-right direction, it can be seen that if the two height adjustment functions 14 are rotated in which direction and how many times, the washing machine main body 9 is brought into a horizontal state.

  That is, assuming that (αf−α3) ° is increased in the front-rear direction, since the two height adjustment functions 14 are both rotated by 1 °, when rotated and rotated (αf−α3) counterclockwise, There is no tilt in the front-rear direction.

  The installer or the user can adjust the height of the washing machine body 9 by operating the height adjusting means 14 as described above according to the displayed and / or informed inclination.

  The operation of displaying and / or notifying the detected inclination in step 110 from the detection of the acceleration detection means 15 in step 107 is repeated until the power-off switch is pressed in step 111, so that the installer or user Can repeat the operation of the height adjusting means 14 in accordance with the displayed and / or notified inclination, thereby correcting the inclination of the washing machine body 9 and bringing it closer to the horizontal installation state. When the power-off switch is pressed in step 111, this series of operations is terminated.

  As described above, in the fifth embodiment, the control unit 17 can set the special operation operation for confirming the inclination of the installed washing machine body by the input setting unit 18, and the input setting unit 18. When the special driving operation is set, the inclination of the washing machine main body 9 is detected by the detection values of the two or three axes detected by the acceleration detecting means 15, and continuously displayed and / or notified. As a result, it is possible to notify the installer or the user to correct the inclination of the installed washing machine body 9 while operating the height adjusting means 14 and to bring it closer to the horizontal state, and to adjust the inclination of the washing machine. can do. As a result, the washing machine can be operated while being level with respect to the floor surface, so that vibration and noise during dehydration can be reduced.

  As described above, the washing machine according to the present invention can inform the installer or the user of the inclination of the floor on which the washing machine is installed, so that the washing machine body can be operated without inclination. Therefore, it can also be applied to applications that require horizontal installation, such as dehydrators and centrifuges.
