[0018] The present invention will be further described below in conjunction with the drawings.

[0019] Reference Figure 1 ~ Figure 3 , A waste heat recovery system for a drinking water machine, comprising a water tank 1 and a heating body 2, the water tank 1 comprising a water inlet cavity 4 and a water vapor separation cavity 3, the water outlet 8 of the water inlet cavity 4 and the water inlet of the heating body 2 9 is connected, the outlet 5 of the heating body 2 is connected with the inlet 6 of the water vapor separation chamber 3, the lower part of the water vapor separation chamber 3 is provided with a hot water outlet 10, and the upper part of the water vapor separation chamber 3 is provided with exhaust steam Port 7, the exhaust port 7 is in communication with the steam inlet 13 of the water inlet cavity 2, and the position of the steam inlet 13 is higher than the water surface of the water inlet cavity 4, and the water inlet cavity 4 is provided with There is a ventilating pipe 11, the inlet of the ventilating pipe 11 is in communication with the water inlet chamber 4, and the outlet of the ventilating pipe 11 is in communication with the atmosphere.

[0020] Further, the water inlet chamber 4 is provided with a steam liquefaction plate 12, the steam liquefaction plate 12 is located in the air intake direction of the steam inlet 13, and the lower end of the steam liquefaction plate 12 is higher than the water surface of the water inlet chamber 4. .

[0021] The steam outlet 7 and the steam inlet 13 are integrated.

[0022] Or: the steam outlet 1 and the steam inlet 13 are connected by a connecting pipe.

[0023] The steam outlet is connected to the steam inlet pipe, the steam inlet pipe is located in the water inlet tank, and the steam inlet pipe passes through the water inlet cavity from bottom to top, and the upper end of the steam inlet pipe is the steam inlet mouth.

[0024] The water inlet 14 of the water inlet cavity is located at the upper or top of the water inlet cavity 4.

[0025] The ventilation tube 11 passes through the water inlet cavity from top to bottom, and the upper end of the ventilation tube 11 is higher than the water surface of the water inlet cavity 4.

[0026] The ventilation tube 11 has a vertical downward shape.

[0027] The ventilation tube 11 is a threaded tube. Of course, other shapes are also possible.

[0028] In this embodiment, there may be one or multiple exhaust ports 7. The closer the position of the steam outlet 7 is to the water surface of the water inlet cavity 4, the better the steam waste heat recovery effect, but it must be higher than the water surface.

[0029] The water inlet cavity 4 provides water inlet to the heating body 2. The normal temperature water in the water inlet chamber 4, after being heated and boiled by the heating body 2, overflows from the heating body outlet 5 into the water vapor separation chamber 3, and steam enters the water vapor separation chamber 3 upward through the steam outlet 7 Into the water inlet cavity 4, hot water flows out through the hot water outlet 10 of the water vapor separation cavity 3.

[0030] The higher the water temperature in the water inlet cavity 4, the greater the hot water output of the heating body 2 will be. The water inlet chamber 4 is provided with a ventilating tube 11, and the steam entering the water inlet chamber 4 is finally discharged into the atmosphere through the ventilating tube 10. The ventilating pipe 11 passes through the water inlet chamber 4 from top to bottom to ensure more effective recovery of steam waste heat.

[0031] In order to more effectively recover the steam waste heat, the water inlet chamber 4 is provided with a steam liquefaction plate 12, which can more effectively exchange the steam with the air in the water inlet chamber 4, thereby increasing the heat in the water inlet chamber 4 Water temperature. A steam liquefaction plate 12 may be provided in the water inlet chamber 4, or a plurality of steam liquefaction plates 12 may be provided, which can more effectively recover the steam waste heat. There should be a gap between the steam liquefaction plate 12 and the water surface of the water inlet chamber 4 to ensure the passage of steam. However, the closer the steam is to the water surface, the higher the steam waste heat recovery efficiency.
