Embodiment approach 1

[0029] figure 1 It is a cross-sectional view showing a schematic structure of the front-loading washing machine according to Embodiment 1 of the present invention, Figure 2A is a sectional view of a circulation pump used in the drum type washing machine, Figure 2B It is a side view of the circulation pump used in this front-loading washing machine.

[0030] The front-loading washing machine according to Embodiment 1 has automatic control according to the mode setting and control program. figure 1 The motor 6, water supply system 7, drainage system 8, and drying system 9 shown perform at least the functions of a washing process, a rinsing process, a dehydration process, and a drying process. However, the drying system 9 can be omitted. In addition, in addition to the above, the water circulation system 16 can be used to circulate the washing water in the water tank 3 during the washing preparation process, the washing process, and the rinsing process as needed, so as to ac...

Embodiment approach 2

[0053] Image 6 It is the rear view which looked at the front wall of the water tank of the front-loading-type washing machine concerning Embodiment 2 of this invention from the direction of the rotation axis of a rotary drum. In Embodiment 2 of the present invention, the same reference numerals are assigned to the same constituent elements as in Embodiment 1, description thereof will be omitted, and different points will be described.

[0054] Such as Image 6 As shown, in a plane perpendicular to the direction of the rotating shaft 10 of the rotating drum 4 , the line connecting the rotation center of the rotating drum 4 and the water inlet 51 is the first line 61 . Then, on both sides of the first line 61 in this plane, a plurality of discharge ports 55d having different distances from the water inlet 51 are provided. The line connecting the center of rotation of the rotary drum 4 and the discharge port 55d near the water inlet 51 is the second line 62, and the line conne...

Abstract

The present invention provides a drum type washing machine which comprises the following components: a rotating drum, a water tank, a motor and a water circulation system. The water circulation system is provided with a water inlet, a water guiding passage, a plurality of jet outlets and a plurality of jet openings. The plurality of jet outlets are open in a preset circumferential range between aback surface of a front wall of the water tank and a front surface of a front wall of the rotating drum. The back surface of the front wall of the water tank is provided with a guiding surface which guides the washing water jetted from the plurality of jet outlets to the inner part of the rotating drum. The washing water jetted from the plurality of jet outlets is caused to flow along the back surface of the front wall of the water tank and the guiding surface, and is jetted from the plurality of jet openings. The opening direction of the plurality of jet outlets and the plurality of jet openings faces a rotation center side of the rotating drum.

Description

technical field [0001] The present invention relates to a drum type washing machine. Background technique [0002] The structure of the conventional front-loading type washing machine is as follows. That is, the rotating drum is formed in a bottomed cylindrical shape, and is installed in the water tank so that the rotating shaft is horizontal from the front side of the opening toward the back side serving as the bottom, or is inclined downward from the horizontal direction. Then, the rotary drum is driven to rotate, and the laundry accommodated in the rotary drum is washed. There is also known a front-loading washing machine having a circulation function for circulating wash water in a water tank by a circulation pump (for example, refer to JP-A-10-127978 and JP-A-2008-073128). [0003] The drum-type washing machine of Japanese Patent Application Laid-Open No. 10-127978 has a plurality of injection ports which are angularly shifted from each other, and sprays into the rota...
