[0041] figure 1 It is a schematic vertical cross-sectional view of washing machine 100 according to the first embodiment. use figure 1 A washing machine 100 will be described.

[0042] Washing machine 100 includes a cabinet 110 and a storage tank 200 for storing laundry in cabinet 110 . The storage tank 200 includes: a rotating drum 210 having a substantially cylindrical peripheral wall 211 surrounding the rotating shaft RX; and a water tank 220 for accommodating the rotating drum 210 . The storage tank 200 has a substantially cylindrical shape surrounding the rotation axis RX. In a washing step described later, the storage tank 200 stores laundry and washing water for washing the laundry. In a dehydration step described later, washing water is discharged from the storage tank 200 . After that, the rotary drum 210 rotates at a high speed.

[0043] Washing machine 100 includes warm water heater 160 for heating washing water. Warm water heater 160 is arranged a...

[0162] Figure 21 It is a schematic expanded perspective view of steam generator 420A used for the washing machine of 2nd Embodiment. The washing machine of the second embodiment has the same structure as the washing machine 100 of the first embodiment except for the structure of the steam generator 420A. Therefore, differences from the first embodiment will be described below. The description of the first embodiment applies to the washing machine of the second embodiment except for the following differences. In addition, the same code|symbol is attached|subjected to the same element as 1st Embodiment. Therefore, the description of the first embodiment is also applied to elements attached with the same symbols.

[0163] The steam generator 420A includes a main piece 423A, a cover piece 424A, and a backing ring 433 sandwiched between the main piece 423A and the cover piece 424A. Unlike the main piece 423 described in association with the first embodiment, no heater is mount...

Abstract

The present application discloses a washing machine (100), which includes: a storage tank (200) for storing washing water for washing clothes; a first heater (160) for heating the washing water; a steam supply mechanism (300) that supplies steam; and a control unit (122) that controls the steam supply mechanism (300) and the first heater (160). The control unit (122) activates the steam supply mechanism (300) after stopping the first heater (160).

Description

technical field [0001] The present invention relates to a washing machine for washing laundry. Background technique [0002] A washing machine has been developed in which steam is supplied to a storage tub for storing clothes to perform various treatments on the clothes (see Patent Document 1 and Patent Document 2). The washing machines disclosed in Patent Document 1 and Patent Document 2 supply steam to the storage tank in synchronization with the start of supply of washing water for washing clothes. Since wash water is heated by steam, the washing machine can exhibit high washing performance. [0003] However, wash water warming techniques that rely on steam are not time efficient. [0004] prior art literature [0005] patent documents [0006] Patent Document 1: European Patent No. 1861534 [0007] Patent Document 2: European Patent No. 2031114 Contents of the invention [0008] An object of the present invention is to provide a high-efficiency washing machine ca...
