Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

As shown in fig. 1 and 2, a condensed water outflow apparatus for a wall-hanging stove includes an inner pipe 100, a sleeve 200, and a drain pipe 400. The inner tube 100 is hollow and has both open upper and lower ends, and the sleeve 200 is installed outside the inner tube 100. The upper end of the sleeve 200 is opened, and the upper end opening of the sleeve 200 is positioned at a height higher than the upper end opening of the inner pipe 100. The inner diameter of the sleeve 200 is larger than the outer diameter of the inner pipe 100, that is, a gap is formed between the sleeve 200 and the inner pipe 100, and the lower end of the sleeve 200 is attached to the outer wall of the inner pipe 100, so that a water collecting cavity 300 with an upper opening is formed between the sleeve 200 and the inner pipe 100. The drain pipe 400 transversely penetrates the casing 200, one end of the drain pipe 400 is connected to the water collecting cavity 300, and the other end is located outside the casing 200 to connect the water collecting cavity 300 to the external environment.

When in use, the condensed water outflow device is arranged at the smoke outlet of the wall-hanging stove and communicated to the smoke cavity of the wall-hanging stove through the lower end opening of the inner pipe 100. The flue gas generated from the wall-hanging stove is discharged upward through the inner pipe 100, and the flue gas rises and is finally discharged to the external environment from the upper end opening of the sleeve 200. In the smoke discharging process, as the upper end opening of the sleeve 200 is in contact with the external environment, condensed water is produced at the position of the height difference between the inner pipe 100 and the sleeve 200, and the condensed water flows downwards along the inner wall of the sleeve 200 and is collected in the water collecting cavity 300. The condensed water in the water collecting cavity 300 is discharged outwards through the water discharging pipe 400, so that the condensed water is effectively prevented from flowing back to the wall-hanging stove, and the service life of internal parts of the wall-hanging stove is prolonged.

In some embodiments of the present invention, an outer tube 500 is installed outside the sleeve 200, a gap is formed between the outer tube 500 and the sleeve 200 to form an air inlet channel 510 with an upper opening and a lower opening, and the outer end of the drain pipe 400 penetrates to the outside of the outer tube 500. As shown in fig. 2, the outer tube 500 has an inner diameter dimension larger than an outer diameter dimension of the sleeve 200, and the drain pipe 400 transversely penetrates the outer tube 500 and the sleeve 200. During the use, air intake channel 510 lower extreme intercommunication hanging stove inner chamber lets in the hanging stove with the outside air through air intake channel 510.

In some embodiments of the present invention, the outer tube 500 is connected to the sleeve 200 by a bracket 520. As shown in fig. 1 and 2, a plurality of brackets 520 are disposed between an inner wall of the outer tube 500 and an outer wall of the sleeve 200, and the outer tube 500 is fixed to the outside of the sleeve 200 by the brackets 520.

In some embodiments of the present invention, the inner tube 100 and the sleeve 200 are stepped shafts with a small upper diameter and a large lower diameter. As shown in fig. 2, the upper diameter of the inner pipe 100 is smaller than the lower diameter thereof, and the upper diameter of the sleeve 200 is smaller than the lower diameter thereof, thereby increasing the axial structural strength of the inner pipe 100 and the sleeve 200. In one embodiment, a water collecting chamber 300 is formed between the middle upper portion of the inner pipe 100 and the middle lower portion of the sleeve 200, so that the water collecting space of the water collecting chamber 300 is increased.

In some embodiments of the present invention, the lower portion of the pipe wall of the inner pipe 100 is provided with a mounting portion 110 protruding outward in the radial direction, and a sealing ring 600 is disposed in the mounting portion 110. The inner pipe 100 is connected to the smoke outlet of the wall-hanging stove, and the sealing performance of the inner pipe 100 and the smoke outlet is improved by the sealing ring 600.

In some embodiments of the present invention, the inner wall of the sealing ring 600 is provided with a plurality of soft rubber strips 610, the soft rubber strips 610 wind the circumferential direction of the inner wall of the sealing ring 600, and the soft rubber strips 610 incline upwards. As shown in fig. 2, two layers of soft rubber strips 610 are arranged in the sealing ring 600, and the sealing effect of the inner pipe 100 and the smoke exhaust port of the wall-hanging stove is enhanced by the upward inclined soft rubber strips 610.
