no. 1 Embodiment approach

[0054] For the first embodiment, refer to Figure 1 to Figure 19 illustrate.

[0055] First, in figure 1 with figure 2 The overall structure of the front-loading washing machine is shown in . The outer case 1 of the front-loading-type washing machine specifically includes a base 1A made of synthetic resin and a case main body 1B coupled to the base 1A. On the front part of the box main body 1B (in figure 1 The roughly central portion of the middle left side) forms the laundry inlet and outlet portion 2 . The door 3 has a double-glazed structure, and opens and closes the laundry inlet and outlet 2 . An operation panel 4 is provided on an upper portion of the front portion of the box main body 1B. On the rear side of the operation panel 4 (inside the outer case 1 ), a control device 5 as a control unit is provided.

[0056] Inside the outer case 1 is provided a bottomed cylindrical water tank 6 with the back side closed. Tank 6 is elastically supported by suspension 7 i...

no. 2 Embodiment approach

[0097] Figure 20 Regarding the second embodiment, for the above-mentioned first embodiment ( Figure 17 ) are assigned the same symbols. This second embodiment deletes the AND current converter 51 (refer to Figure 11 ) related to the judging step S10, processing step S11, judging step S17 and processing step S18. That is, the present embodiment is a configuration in which the current converter 51 is omitted.

no. 3 Embodiment approach

[0099] Figure 21 Relate to the 3rd embodiment, with respect to above-mentioned 1st embodiment (referring to Figure 14 to Figure 16 ) are marked with the same symbols. In this third embodiment, at the initial stage of the washing process, the drum 11 (refer to figure 1 , figure 2 ) of the forward rotation time (in this case, 20 seconds, 30 seconds, 40 seconds) is divided into multiple forward rotation times and stop times to execute. According to this configuration, generation of foam can be suppressed as much as possible.

Abstract

A drum type washing machine is provided with: an outer box; a water tub which has a closed-bottomed cylindrical shape having the rear surface side thereof closed and is elastically supported within the outer box in such a manner that the center axis of the water tub is located on an axis extending downward and rearward; a drum which is provided within the water tub so as to be rotatable about the axis, has a closed-bottomed cylindrical shape having the rear surface side thereof closed, and is provided with a large number of holes in the peripheral wall of the drum; a washing machine motor which is provided to the outside of the rear surface of the water tub and drives the drum in the forward direction and the reverse direction; baffles which are provided to the inner peripheral section of the drum and extend in the front-rear direction along the axis; a water intake opening section which is formed in the bottom of the water tub, said bottom being located on the rear surface side of the water tub; first and second water discharge opening sections which are formed on the front surface side of the water tub at positions in the upper part thereof; a circulation path which connects the water intake opening section and the first and second water discharge opening sections; a circulation pump which is provided in the circulation path and discharges water, which is taken out of the water intake opening section of the water tub, from the first and second water discharge opening sections to the inside of the drum; and a control means which controls the washing machine motor and the circulation pump.

Description

technical field [0001] Embodiments of the present invention relate to a front-loading washing machine including a circulation path for circulating wash water in a water tank. Background technique [0002] Generally, a front-loading washing machine is provided with a bottomed cylindrical water tank whose rear side is closed. The water tank is elastically supported in the outer case so that its central axis is located on the axis descending to the rear. In the water tank, a drum rotationally driven by a washing machine motor is provided to be rotatable. Then, a plurality of baffles for embracing the laundry are provided on the inner peripheral portion of the drum. The baffle is configured to extend straight, for example, in the front-back direction of the water tank. Then, during the washing course of the washing operation, the washing water in which the detergent is dissolved is stored in the water tank. When the drum is rotated, clothes as laundry containing wash water a...
