detailed description

The present invention is described in the following detailed description of the embodiments of the present invention, and is not intended to limit the scope of the present invention.

As shown in Figures 1 and 2, an embodiment of the present invention introduces a washing machine including an outer cylinder 1, a water vapor separator 3 and a steam generator 2, an air outlet of the steam generator 2 and a water vapor inlet of the water vapor separator 3. In communication, the steam outlet of the water vapor separator 3 communicates with the outer cylinder 1 to allow steam separated from the water to pass into the outer cylinder 1.

The purpose of the steam generator 2 supplying water vapor to the outer cylinder 1 is to wrinkle and deodorize the laundry to achieve a fresh stretch of the clothes. However, the steam supplied by the steam generator 2 contains unvaporized liquid water, once the laundry is absorbed. Since the water is too large to cause the laundry to be difficult to dry, the present invention avoids the above by using the water vapor separator 3 to purify the water vapor supplied from the steam generator 2.

As shown in Fig. 1, the drain port 5 of the water vapor separator 3 extends through the drain pipe 7 to the outside of the washing machine.

Preferably, the drain pipe 7 is provided with a "U"-shaped water return bend 8 to block the downward steam from being discharged to the outside of the washing machine.

The above arrangement ensures that steam flows out of the steam outlet 4 and thus passes into the outer cylinder 1. When the drain pipe is in communication with the sewer, the above arrangement prevents the odor from entering the steam separator 1, affecting the deodorizing effect of the steam on the clothes.

It is also possible that, as shown in FIG. 2, the water vapor separator 11 is disposed above the steam generator 2, and the water discharge port 5 of the water vapor separator 3 communicates with the water inlet of the steam generator 2 via the water outlet pipe 10.

The above settings enable the recycling of water and avoid the waste of water resources.

Embodiment 1

After the water vapor supplied from the steam generator 2 enters the water vapor separator 3, the water having a higher density in the water vapor is retained in the water vapor separation chamber 11 by gravity, and the less dense steam rises upward and flows out from the steam outlet 4, thereby It is introduced into the outer cylinder 1.

Embodiment 2

As shown in FIG. 1-3, the difference between the embodiment and the first embodiment is that the water vapor separation chamber 11 is a chamber having a circular cross section, and the air outlet of the steam generator 2 is separated from the water vapor by the water vapor supply tube 9. The water vapor inlet 6 of the device 3 is in communication with each other, and the water vapor inlet 6 is in communication with the water vapor separation chamber 11; the water vapor supply pipe 9 is disposed at an upper portion of the water vapor separation chamber 11 side, and the axis of the water vapor supply pipe 9 is circularly traversed along the water vapor separation chamber 11 Any line setting of the face.

The water vapor supplied from the steam generator 2 enters the water vapor separation chamber 11 in the tangential direction through the water vapor supply pipe 9, and forms a swirling flow rotating along the cavity wall. During the rotation process, the water having a relatively high density in the water vapor is concentrated on the cavity wall, and the density The smaller steam rises upward and flows out of the steam outlet 4 to pass into the outer cylinder 1. The above arrangement improves the separation effect of the water vapor separation chamber 11.

Preferably, the water vapor supply pipe 9 is horizontally disposed.

More preferably, the water vapor supply pipe 9 is disposed tangentially to the circular cross section of the top end of the water vapor separation chamber 11.

The separation effect is deteriorated, that is, water adhering to the wall of the chamber is carried out from the steam outlet 4 by steam carrying, and is introduced into the outer cylinder 1. The water vapor separation chamber 11 of the above structure allows the water on the chamber wall to quickly flow to the drain port 5 and exit the water vapor separation chamber 11.

The height of the inlet 6.

The water vapor supplied from the steam generator 2 enters the water vapor separation chamber 11 in the tangential direction through the water vapor supply pipe 9, and forms a swirling flow rotating along the cavity wall. During the rotation, the density of the components in the water vapor is closer to the water vapor separation chamber 11 The central axis, that is, the steam having the smallest water content, flows out from the steam outlet 4 provided at the center of the top of the water vapor separation chamber 11, and is introduced into the outer cylinder 1. The above arrangement improves the separation effect of the water vapor separation chamber 11.

Preferably, the central axis of the drain port 5 is disposed coaxially with the central axis of the water vapor separation chamber 11, and the drain port 5 is disposed at the lowest point of the water vapor separation chamber 11.
