JP 2019-42265 A

In the washing machine disclosed in Patent Document 1, an amount of detergent to be added determined based on the standard amount of detergent may be added into the washing tub by an automatic input device. In such a washing machine, a standard amount of detergent may be initially set. However, when the standard amount of detergent is initially set, the initially set standard amount may differ from the standard amount recommended for commercially available detergents. For example, while the standard amount recommended for commercially available detergents is 35 ml/30 L, the standard amount initially set for washing machines may be 25 ml/30 L. In such a case, inconvenience may occur when the user of the washing machine uses the washing machine without recognizing the initially set reference amount. For example, it is conceivable that the standard amount initially set in the washing machine is different from the standard amount recommended for the commercially available detergent used in the washing machine, so that the dirt on the laundry cannot be sufficiently washed off. . Therefore, the present specification provides a technology that allows the user to reliably recognize the reference amount of laundry treatment agent that is initially set in the washing machine.

A washing machine disclosed in the present specification includes a washing tub, an automatic loading device for automatically loading a laundry treatment agent into the washing tub, a display section, and a control section. The control unit controls the automatic injection device so that an amount of the laundry treatment agent to be injected determined based on the reference amount of the laundry treatment agent is injected into the washing tub. The control unit displays information on the initially set reference amount of the laundry treatment agent on the display unit.

The washing machine 1 according to the embodiment has been described above. As is clear from the above description, washing machine 1 includes washing tub 13 , automatic loading device 30 for automatically loading detergent into washing tub 13 , display operation section 23 , and control section 21 . The controller 21 controls the amount of detergent (eg, 25 ml) determined based on the standard amount of detergent (eg, 25 ml/30 L) set in the washing machine 1 so that the amount of detergent (eg, 25 ml) is introduced into the washing tub 13. It controls the automatic injection device 30 . The control unit 21 displays information on the reference amount of detergent (for example, 25 ml/30 L) initially set in the washing machine 1 on the display operation unit 23 (see S14 in FIGS. 3A and 3B and FIG. 6). According to this configuration, the user can reliably recognize the reference amount of detergent initially set in the washing machine 1 . This allows the user to recognize the difference between the reference amount (also referred to as the reference amount) set for the commercially available detergent and the reference amount of the detergent initially set in the washing machine 1 .

The washing machine 1 is also provided with an automatic loading setting button 60 for setting the reference amount of detergent. The control unit 21 displays the first notification screen C3 (that is, information on the initially set standard amount of detergent) at the timing when the automatic injection setting button 60 is pressed for the first time in a state where the standard amount of detergent is initially set. It is displayed on the display operation unit 23 (YES in S11 of FIGS. 3A and 3B, NO in S12, S14, see FIG. 6). For example, when the washing machine 1 is shipped from the factory, the first flag is not stored in the storage unit 22 because it is set to the initial setting. When the automatic input setting button 60 is pressed for the first time in this state, the first notification screen C3 is displayed on the display operation unit 23 (S14). The first notification screen C3 displays information on the initially set reference amount of the detergent. According to this configuration, when the user sets the reference amount of detergent for the first time, information on the initially set reference amount is displayed on the display/operation unit 23, so that the user can reliably set the initially set reference amount. can recognize.

Further, in the washing machine 1 described above, after the control unit 21 displays the first notification screen C3 (that is, the information of the initially set reference amount of the detergent) on the display operation unit 23, the same information is automatically displayed next time. At the timing when the input setting button 60 is pressed, the confirmation screen C5 is displayed on the display/operation unit 23 (see S14-S18 in FIGS. 3A and 3B, and FIG. 8) to inquire whether to display it again on the display/operation unit 23 or not. According to this configuration, user convenience can be improved.

The washing machine 1 also includes a plurality of transition buttons (for example, the "Next" button 63, the automatic input setting button 60, the "Yes" button 66, the " No" button 67). When a plurality of transition buttons are pressed after displaying the information of the initially set reference amount on the display operation unit 23, the control unit 21 causes the screen displayed on the display operation unit 23 to transition to display the reference amount. is displayed on the display operation unit 23 (S14-S23 in FIGS. 3A-B, see FIG. 5A). According to this configuration, after the initially set reference amount of detergent is displayed on the display operation unit 23, the screen can be changed to the automatic input setting screen C2 for setting the reference amount. A new reference amount can be set while recognizing the existing reference amount. Therefore, the user can set an appropriate reference amount.

Further, in the washing machine 1 described above, after the control unit 21 displays the information of the initially set reference amount on the display operation unit 23, the second notification screen C4 for explaining how to use the automatic loading device 30 is displayed. It is displayed on the operation unit 23 (S14-S16 in FIGS. 3A-B, see FIG. 7). According to this configuration, the user can recognize how to use the automatic loading device 30 while recognizing the initially set reference amount. Therefore, the user can use the automatic loading device 30 appropriately.

Although one embodiment has been described above, specific aspects are not limited to the above embodiment. In the following description, the same reference numerals are given to the same configurations as those in the above description, and the description thereof is omitted.

(Second embodiment)
A second embodiment will be described. In the second embodiment, the second flag is stored in the storage unit 22 (see FIG. 2) of the washing machine 1. FIG. The second flag is information for determining whether or not the control unit 21 should display the first notification screen C3 (see FIG. 6) on the display operation unit 23 . In the initial setting of washing machine 1 , the second flag is not stored in storage unit 22 . The washing machine 1 is initialized, for example, when it is shipped from the factory. The second flag is generated and stored in the storage unit 22 in the process of S35 of the second display process (see FIGS. 9A and 9B), which will be described later.

Next, the second display process executed by the washing machine 1 will be described. 9A and 9B are flowcharts of second display processing according to the second embodiment. As shown in FIGS. 9A and 9B, in the second display process, processes from S30 to S35 are executed. In S30 of the second display process, the control unit 21 of the washing machine 1 determines whether or not the power of the washing machine 1 is turned on. When the power button 12 (see FIG. 1) of the washing machine 1 is pressed while the power of the washing machine 1 is off, the power of the washing machine 1 is turned on. For example, when the washing machine 1 is shipped from the factory, the power of the washing machine 1 is turned off. If the washing machine 1 is powered on, the controller 21 determines YES and proceeds to S31. Otherwise, the control unit 21 determines NO and waits.

In subsequent S31, the control unit 21 determines whether or not the storage unit 22 has the second flag. The second flag does not exist in the storage unit 22 in the initial settings of the washing machine 1 . For example, the second flag does not exist in the storage unit 22 when the washing machine 1 is shipped from the factory. Therefore, the second flag does not exist in the storage unit 22 at the timing when the power button 12 is pressed for the first time after shipment from the factory and the power of the washing machine 1 is turned on for the first time. When the second flag is generated and stored in the storage unit 22 in the process of S35, which will be described later, the second flag exists in the storage unit 22. FIG. When the second flag exists in the storage unit 22, the control unit 21 determines YES and proceeds to S32. Otherwise, the control unit 21 determines NO and proceeds to S14. The processing from S14 to S21 after NO in S31 is the same as the processing from S14 to S21 after NO in S12 of the first display processing (see FIGS. 3A and 3B), so a detailed description thereof will be omitted.

On the other hand, in S32 after YES in S31, the control unit 21 displays the operation content selection screen C1 on the display operation unit 23 (see FIG. 4). In subsequent S33, the control unit 21 determines whether or not the automatic input setting button 60 displayed on the operation content selection screen C1 (see FIG. 4) has been pressed. When the automatic injection setting button 60 is pressed, the control unit 21 determines YES and proceeds to S34. Otherwise, the control unit 21 determines NO and waits. In subsequent S34, the control unit 21 displays the automatic input setting screen C2 on the display operation unit 23 (see FIG. 5A). When the process of S34 is completed, the control unit 21 proceeds to "C" and proceeds to S24. The processing from S24 to S26 is the same as the processing from S24 to S26 of the above-described first display processing (see FIGS. 3A and 3B), so detailed description will be omitted.

In the second embodiment (second display process), in S<b>35 after YES in S<b>21 , the control unit 21 generates a second flag and stores it in the storage unit 22 . Note that after YES in S20, the control unit 21 does not generate the second flag. Therefore, the second flag is not stored in the storage unit 22 after YES in S20. A second flag is generated and stored in the storage unit 22 only when the "No" button 67 is pressed in S21.

The second embodiment has been described above. As is clear from the above description, in the second embodiment, the control unit 21 causes the first notification screen C3 (that is, the information on the initially set reference amount of the detergent) is displayed on the display operation unit 23 (YES in S30 of FIGS. 9A and 9B, NO in S31, S14, see FIG. 6). For example, when the washing machine 1 is shipped from the factory, the second flag is not stored in the storage unit 22 because it is set to the initial setting. When the power button 12 is pressed for the first time in this state, the first notification screen C3 is displayed on the display operation unit 23 (S14). The first notification screen C3 displays information on the initially set reference amount of the detergent. According to this configuration, the information of the initially set reference amount is displayed on the display/operation unit 23 at the timing when the user turns on the power of the washing machine 1 for the first time. can be recognized with certainty.

(Third embodiment)
A third embodiment will be described. In the third embodiment, the 0 (zero) time flag is stored in the storage unit 22 (see FIG. 2) in the initial setting of the washing machine 1 . The 0 times flag is stored in the storage unit 22 when the washing machine 1 is shipped from the factory. Also, the flag is stored twice in the storage unit 22 . In the initial settings of the washing machine 1, the storage unit 22 does not store the twice flag. The twice flag is not stored in the storage unit 22 when the washing machine 1 is shipped from the factory. The twice flag is generated in the process of S44 of the injection detection process (see FIG. 10), which will be described later, and stored in the storage unit 22 . The 0 times flag and the 2 times flag are information for determining whether or not the control unit 21 displays the first notification screen C3 (see FIG. 6) on the display/operation unit 23 .

Also, in the third embodiment, the storage unit 22 stores the third flag. In the initial setting of washing machine 1, storage unit 22 does not store the third flag. The third flag is not stored in the storage unit 22 when the washing machine 1 is shipped from the factory. The third flag is generated and stored in the storage unit 22 in the process of S59 of the second display process (see FIGS. 11A to 11C), which will be described later. The third flag is information for determining whether or not the control unit 21 should display the first notification screen C3 (see FIG. 6) on the display/operation unit 23 .

Next, the injection detection process executed in the washing machine 1 will be described. FIG. 10 is a flowchart of injection detection processing according to the third embodiment. As shown in FIG. 10, in S40 of the injection detection process, the control unit 21 of the washing machine 1 determines whether the injection detection unit 32 has detected that detergent has been injected into the detergent tank 31 of the automatic loading device 30. to judge. When the injection detection unit 32 detects that the detergent has been injected into the detergent tank 31, the control unit 21 determines YES and proceeds to S41. Otherwise, the control unit 21 determines NO and waits.

In subsequent S41, the control unit 21 determines whether or not the storage unit 22 has a 0 times flag. In the initial setting of the washing machine 1, the storage unit 22 has a 0-time flag. For example, when the washing machine 1 is shipped from the factory, the storage unit 22 has a 0-time flag. Therefore, the 0 times flag exists in the storage unit 22 at the timing when the injection detection unit 32 first detects that the detergent has been injected into the detergent tank 31 after shipment from the factory. When the 0 times flag exists in the storage unit 22, the control unit 21 determines YES and proceeds to S42. Otherwise, the control unit 21 determines NO and proceeds to S43. In S<b>42 after YES in S<b>41 , the control unit 21 deletes the 0 times flag stored in the storage unit 22 . Therefore, the 0 times flag does not exist in the storage unit 22 .

In S<b>43 after NO in S<b>41 , the control unit 21 determines whether or not the storage unit 22 has the twice flag. In the initial setting of the washing machine 1, the storage unit 22 does not have the twice flag. For example, the twice flag does not exist in the storage unit 22 when the washing machine 1 is shipped from the factory. If the storage unit 22 has the flag twice, the control unit 21 determines YES and terminates the injection detection process. If the twice flag does not exist in the storage unit 22, the control unit 21 determines NO and proceeds to S44. In S<b>44 after NO in S<b>43 , the control unit 21 generates a flag twice and stores it in the storage unit 22 .

A state in which the 0-time flag does not exist and the 2-time flag does not exist in the storage unit 22 of the washing machine 1 is after the injection detection unit 32 detects that the detergent has been injected into the detergent tank 31 once. state. That is, this state is the state after the injection detection unit 32 detects for the first time that detergent has been injected into the detergent tank 31 after shipment from the factory. Thereafter, when the injection detection unit 32 detects that detergent has been injected into the detergent tank 31, a flag is generated twice and stored in the storage unit 22 (YES in S40, NO in S41, NO in S43). ). That is, when the injection detection unit 32 detects that the detergent has been injected into the detergent tank 31 twice, a flag is generated twice and stored in the storage unit 22 . As described above, the injection detection process ends.

Next, the second display processing executed in the third embodiment will be explained. 11A to 11C are flowcharts of second display processing according to the third embodiment. As shown in FIGS. 11A to 11C, the processing from S14 to S26 and the processing from S30 to S35 of the second display processing according to the third embodiment are the second display processing according to the second embodiment ( This is the same as the processing from S14 to S26 and the processing from S30 to S35 in FIGS. 9A and 9B). Therefore, detailed description of these processes is omitted.

As shown in FIGS. 11A to 11C, in S50 after YES in S33, the control unit 21 of the washing machine 1 determines whether any of the 0-time flag, the 2-time flag, and the 3rd flag exists in the storage unit 22. or not. When at least one of the 0 times flag, the 2 times flag, and the 3rd flag exists in the storage unit 22, the control unit 21 determines YES and proceeds to S34. Otherwise, the control unit 21 determines NO, proceeds to "D", and proceeds to S51. That is, when none of the 0 times flag, the 2 times flag, and the 3rd flag exists in the storage unit 22, the control unit 21 determines NO and proceeds to S51.

A state in which neither the 0-time flag nor the 2-time flag exists in the storage unit 22 is a state after the injection detection unit 32 detects once that the detergent has been injected into the detergent tank 31 . That is, this state is the state after the injection detection unit 32 detects for the first time that detergent has been injected into the detergent tank 31 after shipment from the factory. Moreover, the third flag does not exist in the storage unit 22 in the factory default setting of the washing machine 1 . When the third flag is generated and stored in the storage unit 22 in the process of S59 to be described later, the third flag exists in the storage unit 22 .

In S51 after NO in S50, the control unit 21 displays the first notification screen C3 on the display operation unit 23 (see FIG. 6). The processing of S51 is the same as the processing of S14 of the first display processing (see FIGS. 3A and 3B), so detailed description thereof will be omitted. Further, the subsequent processing from S52 to S58 is the same as the processing from S15 to S21 of the first display processing (see FIGS. 3A and 3B), so detailed description thereof will be omitted.

In the third embodiment, in S<b>59 after YES in S<b>58 , the control unit 21 generates a third flag and stores it in the storage unit 22 . Note that after YES in S57, the control unit 21 does not generate the third flag. Therefore, the third flag is not stored in the storage unit 22 after YES in S57. A third flag is generated and stored in the storage unit 22 only when the "No" button 67 is pressed in S58. When the process of S59 is completed, the control unit 21 proceeds to "E" and proceeds to S23. After that, the processes of S25 and S26 are executed. As described above, the second display process according to the third embodiment ends.

The third embodiment has been described above. As is clear from the above description, in the third embodiment, after the injection detection unit 32 first detects that the detergent has been injected into the detergent tank 31, the control unit 21 presses the automatic injection setting button 60 (FIG. 4). ) is pressed for the first time, the first notification screen C3 (that is, information on the initially set reference amount of detergent) is displayed on the display operation unit 23 (NO in S33 and S50 in FIGS. 11A to 11C, S51 reference). According to this configuration, information on the initially set reference amount of detergent is displayed on the display/operation unit 23 at the timing when the automatic dispenser 30 is used for the first time. Therefore, the user can recognize the initially set reference amount of the detergent at an appropriate timing.

If the tank cleaning operation has been executed, the controller 21 determines YES and proceeds to S61. Otherwise, the control unit 21 determines NO and waits. In subsequent S<b>61 , the control unit 21 generates a cleaning flag and stores it in the storage unit 22 .

Next, the third display process executed by the washing machine 1 will be described. 13A and 13B are flowcharts of third display processing according to the fourth embodiment. As shown in FIGS. 13A and 13B, in the third display process, the processes of S70 and S71 are executed. The processing of S10 and S11, the processing of S14 to S21, and the processing of S23 to S26 of the third display processing are the processing of S10 and S11, the processing of S14 to S21, and the processing of S14 to S21 of the first display processing (FIGS. 3A and 3B). Since the processing is the same as the processing up to and from S23 to S26, detailed description thereof will be omitted.

In S<b>70 after YES in S<b>11 of the third display process, the control unit 21 determines whether or not the cleaning flag exists in the storage unit 22 . When the tank cleaning operation is executed in the washing machine 1 , the cleaning flag is stored in the storage unit 22 . Therefore, the cleaning flag exists in the storage unit 22 at the timing when the automatic injection setting button 60 is pressed for the first time after the tank cleaning operation is executed. If the cleaning flag exists in the storage unit 22, the control unit 21 determines YES and proceeds to S14. Otherwise, the control unit 21 determines NO, proceeds to " F ", and terminates the third display process.

Further, in S71 after YES in S21 of the third display process, the control unit 21 deletes the cleaning flag stored in the storage unit 22. FIG. Note that after YES in S20 above, the control unit 21 does not delete the cleaning flag. The cleaning flag is deleted only when the "No" button 67 is pressed in S21.

The fourth embodiment has been described above. As is clear from the above description, in the fourth embodiment, the control unit 21 operates when the automatic input setting button 60 (see FIG. 4) is pressed for the first time after the tank cleaning operation for cleaning the inside of the detergent tank 31 is executed. At this timing, the first notification screen C3 (that is, the information of the initially set reference amount of detergent) is displayed on the display/operation unit 23 (YES in S11, YES in S70, and S14 in FIGS. 13A and 13B). At the timing when the automatic charging setting button 60 is pressed for the first time after the tank cleaning operation is executed, the automatic charging device 30 is considered to be used. Since the first notification screen C3 is displayed at that timing, the user can recognize the initially set reference amount of the detergent at an appropriate timing.
