Embodiment approach 1

[0039] figure 1 A sectional view showing the front-loading washing machine in Embodiment 1 of the present invention.

[0040] Such as figure 1 As shown, the drum type washing machine mainly includes: housing 2, water tank 2, suspension 3, rotating tank 4, openings 5, 6, door 7, motor 9, protrusion 12, water supply valve 15, drain valve 19, circulating waterway 20. Pump 21, nozzle waterway 22, nozzle 26.

[0041] In addition, a control unit 32 is provided at the rear lower part of the casing 1, and the control unit 32 is used to control the motor 9, the water supply valve 15, the drain valve 19, the pump 21, etc., and controls washing, rinsing, The actions of each step of dehydration.

[0042] A tank 2 formed in a cylindrical shape with a bottom is elastically supported in the casing 1 by a suspension 3 . Moreover, the rotary tank 4 formed in the shape of a bottomed cylinder is rotatably arrange|positioned in the water tank 2. As shown in FIG. The rotation axis 4a of the...

Embodiment approach 2

[0093] Figure 6 of the front-loading washing machine according to Embodiment 2 of the present invention figure 1 3-3 arrow direction view. This embodiment is different from the first embodiment in that the nozzle water channel 22 is provided at a position other than the direction directly below the rotation shaft 4a (vertical direction). In addition, other structures are the same as those of Embodiment 1, and the contents of Embodiment 1 are cited as the detailed description thereof.

[0094] Usually, since the washing water is accumulated in the lower part of the rotary tub 4, the washing water is supplied to the laundry at this position. Therefore, even if the washing water sprayed from the nozzle 26 is sprayed from the direction directly below (the vertical direction) of the rotating shaft 4a of the rotating tub 4, the effect is limited. Therefore, the nozzle water channel 22 is provided at a position other than the direction directly below (the vertical direction) of ...

Embodiment approach 3

[0104] Figure 7 of the front-loading washing machine in Embodiment 3 of the present invention figure 1 3-3 arrow direction view. In the present embodiment, nozzles 26a to 26f are configured to spray washing water toward positions other than the direction directly below the rotation shaft 4a (vertical direction). In addition, other structures are the same as those of Embodiment 1, and the contents of Embodiment 1 are cited as the detailed description thereof.

[0105] Since the washing water is accumulated in the lower part of the rotary tub 4, the washing water is supplied to the laundry present at this position. Therefore, the washing water is sprayed so that the spraying direction a of the washing water is directed to a position other than the direct downward direction (vertical direction) of the rotation shaft 4a. Accordingly, washing water can be efficiently and uniformly supplied to the entire laundry, thereby improving washing performance and rinsing performance.

Abstract

A drum-type washing machine includes a water tub for storing wash water, a rotary drum placed rotatably in the water tub and having an opening at the front, a motor for driving the rotary drum, a water circulating path for circulating the wash water stored in the water tub to the drum, a pump for conveying the wash water stored in the water tub to the water circulating path, multiple nozzles for jetting the wash water, conveyed to the nozzle water path by the pump, into the rotary drum, and a nozzle water path formed around a front face of the water tub for conveying the wash water from the water circulating path to the nozzles.

Description

technical field [0001] The present invention relates to a drum type washing machine for washing clothes and the like. Background technique [0002] The structure of the conventional front-loading type washing machine is shown, for example in Unexamined-Japanese-Patent No. 10-127978 (patent document 1). The drum type washing machine includes: a pump, which is used to deliver the washing water in the water tank to the circulating water channel; a nozzle, which has a plurality of spray holes, and the multiple spray holes are in front of the rotating tank, and the angle of spraying the washing water is from The front of the rotating groove gradually changes to the depth of the rotating groove. In addition, the rotational speed of the rotary tub is controlled in order to quickly wet the entire laundry and prevent laundry bias between wet and non-wet laundry and between wet laundry. This improves the tumbling effect brought about by the rotation in the spin tank, thereby shorten...
