Detailed ways

The technical solutions of the present invention are further described below with reference to the accompanying drawings and through specific embodiments.

The invention provides an observation window for a washer/dryer. The top of the observation window is provided with an oblique cut surface, and a guide channel for hot air to pass through is formed on the oblique cut surface, and the guide channel is used for drying the washer/dryer The hot air is introduced into the area close to the inner side of the observation window, so that the clothes are dried more evenly, thereby greatly improving the drying efficiency of the clothes.

Aiming at the above observation window, the present invention also provides a washing/drying machine. Due to the use of the above observation window, the clothes are dried evenly and the drying efficiency is high.

Example 1:

This embodiment provides an observation window for a washing/drying machine. As shown in FIGS. 3 and 4 , a guide channel for hot air to pass through is formed on the oblique cut surface 1 of the observation window, and the guide channel is the inward direction of the entire oblique cut surface 1 recessed groove 2. The inner surface of the groove 2 is formed by smoothly connecting the first curved surface 3 and the second curved surface 4 with different curvatures.

One end of the first curved surface 3 and the second curved surface 4 both extend to the outer peripheral surface 6 of the observation window and have a smooth transition with the outer peripheral surface 6, and the other ends both extend to the inner side 7 of the observation window and between the inner side 7 for a smooth transition. By setting the chamfered surface 1 in the form of an inwardly concave groove, as shown in FIG. 5 , the drying hot air can enter the area corresponding to the inner side surface 7 of the observation window under the guiding action of the groove 2, so that the clothes are dried more efficiently. It is uniform and has high drying efficiency. In addition, the observation window of this structure can effectively prevent the clothes from being entangled due to the small cut surface.

Further, the first curved surface 3 and the second curved surface 4 are asymmetrical structures, and the projection line of the valley bottom connecting line 5 of the groove 2 on the inner side surface 7 of the observation window is connected to the two ends of the intersection of the oblique plane 1 and the inner side surface 7 of the observation window. The vertical line 8 on the inner side surface 7 of the line is arranged to cross, so that the guide channel is inclined along the rotation direction of the drum, and the guiding effect on the hot air is further improved.

Among them, the guide channel is not limited to the groove 2 formed by the inward depression of the entire chamfered surface 1, but also can be formed by a part of the chamfered surface 1. The projection line of the valley bottom connecting line 5 of the groove 2 on the inner side surface 7 of the observation window is the same as The angle α between the vertical line 8 on the inner side 7 of the line connecting the two ends of the chamfer plane 1 and the inner side 7 of the observation window is not limited to 25°, and can be set according to the specific drum speed, drum size and other factors. The preferred range is 15 to 35°.

Embodiment 2:

This embodiment provides an observation window for a washing/drying machine, the structure of which is basically the same as that of the first embodiment, and a guide channel for hot air to pass through is formed on the oblique section of the observation window. The difference is that, as shown in the figure As shown in 6, the guide channel in this embodiment is a groove 2 formed by inwardly concave part of the chamfered surface 1 . One end of the groove 2 extends to the edge of the chamfered surface 1 and has a smooth transition with the chamfered surface 1 , and the other end extends to the inner side 7 of the observation window and has a smooth transition with the inner side 7 . The groove 2 is arc-shaped on the cross section perpendicular to its axis, that is, the inner surface of the groove 2 is an inclined semi-cylindrical surface, and the projection line of the axis of the semi-cylindrical surface on the inner side 7 of the observation window is the same as the inner side of the observation window. The vertical line on the inner side surface 7 of the line connecting the two ends of the 7 handover is set to cross. The guiding channel of this structure can also achieve a good hot air guiding effect.

Wherein, the groove 2 in this embodiment is not limited to being formed by a part of the chamfered surface 1 concave, and may also be the entire chamfered surface 1 concave.
