Embodiment approach 1

[0057] [1-1. Overall structure]

[0058] figure 1 It is a sectional view of a main part of the washing machine according to Embodiment 1 of the present disclosure. figure 2 It is a cross-sectional view of main parts showing a state in which the lid of the washing machine according to the present embodiment is opened.

[0059] Such as figure 1 As shown, the washing machine 1 has a lower sink portion 6 and an upper cover body 5 . In addition, washing machine 1 has control unit 26 and operation display unit 27 .

[0060] The water tank unit 6 includes a washing tank 4 having a predetermined depth. In this embodiment, the cleaning tank 4 is formed in a square shape. An opening 3 is formed on the upper surface of the washing tank 4 . Laundry such as clothes (hereinafter referred to as to-be-washed object 2 ) is taken out or put in through the opening 3 .

[0061] The lid body 5 opens and closes the opening 3 of the washing tank 4 . Use the hinge part 6a to rotate the cov...

Embodiment approach 2

[0160] In the present embodiment, when the object 2 is pressed by the plurality of pressing parts 8 in the pressing step, the timing of pressing and releasing the pressing is different from the example shown in the first embodiment.

[0161] [2-1. Washing process]

[0162] Figure 7 It is a time chart showing the operation of the washing process of the washing machine according to Embodiment 2 of the present disclosure.

[0163] In this embodiment, one pressing part 8 (first pressing part 8a) expands and presses the object 2 to be cleaned while the other pressing part 8 (second pressing part 8b) is repeatedly expanded and contracted a plurality of times. Actions. The other configurations are the same as those in Embodiment 1, and the same reference numerals are attached to the same configurations, and the contents of Embodiment 1 are referred to for the detailed description.

[0164] Such as Figure 7 As shown, in the preparatory process, the control unit 26 first closes t...

Abstract

A washing machine (1) comprises a cleaning tub (4) which contains an item to be cleaned (2) and cleaning water; a plurality of pressing sections (8a, 8b) each of which performs pressing of the item tobe cleaned (2) and removal of the pressing thereof; and a control unit (26) which, in a state in which the item to be cleaned (2) is being pressed by at least one of the plurality of pressing sections (8a, 8b), removes the pressing of the item to be cleaned (2) by another at least one of the plurality of pressing sections (8a, 8b).

Description

technical field [0001] The present disclosure relates to a washing machine for washing laundry such as clothes. Background technique [0002] As a conventional washing machine, there is a so-called vertical washing machine in which laundry such as clothes is stirred and washed in a rotary tub. In addition, there is a so-called front-loading type washing machine in which laundry is lifted along the rotation direction of the rotary tank inside the rotary tank, and the laundry is dropped from above to be pat-washed. All of the above-mentioned washing machines perform washing by rubbing or rubbing the laundry by applying mechanical force to the laundry, so the laundry is easily damaged. Therefore, in particular, laundry that is likely to be damaged by cloth and laundry that is easily lost due to being entangled with each other is generally washed by hand. In addition, various considerations have been made about a washing machine that washes laundry without strongly acting a me...
