The difference D of bottom H1 and detection faces H2 that choke box 2e is configured to cylinder 3 becomes more than the metrical error (such as 20mm) of level sensor 34.In addition, horizontal plane 2f2 extends in the cylindrical shell of choke box 2e in the mode becoming the same face.

, as comparative example as shown in Fig. 8 (b), be provided with in the washing machine of water discharge outlet 121 immediately below choke box 122e, if make the circular flow of washings increase, then produce problem shown below.That is, if make the circular flow of washings increase, then the flow velocity flowing through the washings of the bottom of the hole 122e1 of choke box 122e uprises, and is involved in the air in choke box 122e, and washings are immersed in choke box 122e.Thus, the H11 change of water level detecting face, existing can not the problem of correctly sensed water level.

Therefore, in the present embodiment, as shown in Fig. 8 (a), by drainage joint 21a is configured at the position more closer to the front than the bottom surface 3c of cylinder 3, washings can not by immediately below choke box 2e.Thus, washings are made to immerse in choke box 2e, so the water level in water jacket 2 correctly can be detected because of the air that is involved in choke box 2e can be prevented.

Fig. 9 (a) represents the top view from the bottom of water jacket towards the runner of circulating pump, Fig. 9 (b) be represent as comparative example from the bottom of water jacket towards the top view of the runner of circulating pump.

; in the comparative example shown in Fig. 9 (b); the drainage joint 121a of water discharge outlet 121 is configured to overlapping with carrying accessory 150 (with reference to Fig. 8 (b)) above-below direction, and drainage joint 121a is handled upside down the side that accessory 150 surrounds below and left and right.Therefore, corrugated flexible hose 122 can not be linked towards circulating pump 124 side, need corrugated flexible hose 122 rearward pull-out for the time being to make it be connected with circulating pump 124 around carrying accessory 150.Its result, corrugated flexible hose 122 elongated (such as 460mm), the flow passage resistance force of waterproof of washings increases, the constricted flow of washings when the circular flow of washings increases, and exists thus because circulating pump 124 is involved in the hidden danger of air and vent plug.

Therefore as shown in Fig. 9 (a), in the present embodiment, by the drainage joint 21a be connected with water discharge outlet 21 being configured at the position than carrying accessory 50 (with reference to Fig. 8 (a)) more forward side, carrying accessory 50 (rising portions 52) is made not to be positioned at the side being configured with circulating pump 24.Thereby, it is possible to connect corrugated flexible hose 22 in circulating pump 24 side (diagram left side), thus corrugated flexible hose 22 can be made to shorten.Like this, corrugated flexible hose 22 can be made to shorten, reduce the flow passage resistance force of waterproof of washings thus, even if make the circular flow of washings increase also can prevent circulating pump 24 vent plug.

In addition, in the comparative example of Fig. 9 (b), the water inlet interface 123a of filter head housings 123 (illustrates left side) laterally relative to the central shaft of this filter head housings 123 and configures with staggering.To this, in the present embodiment shown in Fig. 9 (a), shorten the length of corrugated flexible hose 22 by configuration water inlet interface 23a above filter head housings 23.Thereby, it is possible to be reduced by the flow passage resistance force of waterproof of the washings of corrugated flexible hose 22 further.
