first embodiment

Washing Machine

[0033]FIG. 1 is a schematic vertical cross-sectional view of the washing machine 100 according to the first embodiment. The washing machine 100 is described with reference to FIG. 1.

[0034]The washing machine 100 includes a housing 110 and a storage tub 200 which stores laundry in the housing 110. The storage tub 200 includes a rotary drum 210, which has a substantially cylindrical peripheral wall 211 surrounding a rotational axis RX, and a water tank 220, which stores the rotary drum 210.

[0035]The housing 110 includes a front wall 111 provided with a loading opening to load laundry into the storage tub 200, and a rear wall 112 opposite to the front wall 111. The rotary drum 210 and the water tank 220 open towards the front wall 111.

[0036]The washing machine 100 further includes a door 120 which is attached to the front wall 111. The door 120 rotates between a closed position, at which the door closes the loading opening formed in the front wall 111, and an open positi...

second embodiment

[0115]FIG. 17 is a schematic exploded perspective view of a steam generator 420A which is used in a washing machine exemplified as the laundry processing apparatus according to the second embodiment. The washing machine according to the second embodiment has similar structures to the washing machine 100 according to the first embodiment, except for structures of the steam generator 420A. Therefore, differences from the first embodiment are described below. The description of the first embodiment may be applied to the washing machine of the second embodiment, except for the differences described below. The same reference numerals are assigned to the same elements as the first embodiment. Consequently, the description of the first embodiment may be applied to the elements to which the same reference numerals are assigned.

[0116]The steam generator 420A includes a main piece 423A, a lid piece 424A, and a packing ring 433 which is sandwiched between the main piece 423A and the lid piece ...

Abstract

The present application discloses a laundry processing apparatus including: a storage tub which stores laundry; a steam supply mechanism which supplies steam to the storage tub; and a water supply valve which supplies water from an external water source to the steam supply mechanism. The steam supply mechanism includes: a water storage tank storing the water, which is supplied from the water supply value; a steam generator which generates the steam; and a pump which supplies the water in the water storage tank to the steam generator.

Description

TECHNICAL FIELD[0001]The present invention relates to a laundry processing apparatus for washing, spin-drying and / or drying laundry.BACKGROUND ART[0002]Washing machines which supply steam to laundry for sterilization have been developed (Patent Documents 1 and 2). The washing machine according to Patent Document 1 generates steam by using a heater immersed in water.[0003]The washing machines according to Patent Documents 1 and 2 supply steam to a drum in which laundry is stored. However, because of a low pressure of steam supplied to the drum, a space inside the drum has to be filled with the steam. Consequently, the washing machines according to Patent Documents 1 and 2 consume a large amount of power in order to generate steam.[0004]Patent Document 1: EP2039823[0005]Patent Document 2: EP2044255SUMMARY OF THE INVENTION[0006]It is an object of the present invention to provide a laundry processing apparatus with a structure to efficiently supply steam to laundry.[0007]The laundry pro...
