Problems solved by technology

[0009] Therefore, although it is undoubtedly preferable to display the amount of detergent as an estimated amount, when the user strictly applies the above-mentioned prior art, the time for displaying the amount of detergent may not be appropriate, and unnecessary unnecessary washing will occur as described above. Abnormal display, or delay in start of washing operation

no. 1 approach

[0039] Below, refer to Figure 1 to Figure 6 , and a first embodiment applied to a vertical axis type fully automatic washing machine will be described. first, figure 1 , figure 2 The structure of the main body of the washing machine (fully automatic washing machine) according to this embodiment is schematically shown. Here, the washing machine main body 1 is equipped with the outer case 2 which consists of steel plates, for example, and is comprised in rectangular box shape as a whole. Such as figure 1 As shown, a platform 4 is provided at the bottom of the outer box 2 , and the platform 4 has four legs 3 .

[0040] Such as figure 1 As shown, the outer box 2 is provided with a water tank 6 for storing washing water, and the water tank 6 is elastically supported (suspended) by an elastic suspension mechanism 7 . As partially shown, the elastic suspension mechanism 7 has a well-known structure, for example, four suspension rods 7a and springs 7b, etc., and the four suspe...

no. 2 approach

[0073] Next, refer to Figure 7 as well as Figure 8 , and the second embodiment will be described. In addition, each embodiment described below is also applied to the vertical shaft type washing machine provided with the same mechanical structure as the said 1st Embodiment. Therefore, the same reference numerals are assigned to the same parts as those of the above-mentioned first embodiment, new illustrations and detailed descriptions are omitted, and the differences will be mainly described below.

[0074] This second embodiment differs from the above-mentioned first embodiment in that the amount of detergent used as an estimated amount used in washing is not set based on the result of the laundry amount detection operation, but is determined according to the quantity of detergent injected into the water tank 6 (rotary tank 11 ). The set water level (water volume) of the water supply is set. That is, in this embodiment, the user can press the water level key 39 of the ope...

no. 3 approach

[0081] Figure 9 The third embodiment is shown, and it is a flowchart showing the procedure of processing executed by the control device 31 from when the power-on key 32 is turned on to when the water supply is started. This third embodiment is different from the above-mentioned first embodiment ( Figure 5 ) is different in that the control device 31 stops shortening the display time of the detergent amount when the lid switch 29 detects the open state of the cover 21 during the display of the amount of detergent on the washing time display portion 41 .

[0082] Here, "stop shortening" refers to returning the display time of the detergent amount to the first time (60 seconds) when directly setting (shortening) the display time of the detergent amount to the second time (8 seconds). , or make the total time longer than the first time (60 seconds), however, it also includes a case where the display time already set as the first time (60 seconds) is further extended as the tota...

Abstract

A washing machine of the embodiment includes a washing tank located in a washing machine body, and used for containing washings and executing washing; an entrance for putting washings in the washing tanks; a lid capable of enclosing the entrance in an opening and closing mode; a lid opening and closing detection unit for detecting the opening and closing of the lid; an operation part used for setting and instruction; a display part used for displaying; and a control device used for executing washing operation. The control device has a washing-amount display control means for displaying a predetermined amount of the washing amount used as washing in the display section before starting the washing operation, and in a normal period, a washing-amount display control means displays a washing-amount in a preset first time period; in addition, in a period from connecting the power supply of a washing machine body to the displaying of a washing-amount, when the cover is detected to be closed from an opening state by the lid opening and closing detecting unit, the display of a washing-amount is executed in a second time shorter than a first time.

Description

[0001] This application is based on Japanese patent application No. 2015-105491 filed on May 25, 2015, and enjoys the benefit of priority of this application, and the entire content of this application is incorporated herein by reference. technical field [0002] Embodiments of the present invention relate to washing machines. Background technique [0003] In a washing machine, such as a so-called vertical axis type fully automatic washing machine, when the start key is turned on, the laundry contained in the rotary tank (washing tank) is cleaned before starting the washing operation (water supply stroke). Clothes amount detection action. Then, the water level (supplied water amount) is determined based on the detected amount of laundry, and the amount of detergent used as an estimated amount used in washing is displayed on the display unit. [0004] However, for different users, the display time is too short, and the time for injecting the displayed amount of detergent int...
