In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0020] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0021] Refer to the following Figure 1-3 A steam drying box according to some embodiments of the present application is described.

[0022] A steam drying box comprises a hollow box body 1, wherein the top wall of the box body 1 is provided with an air inlet 2, and the bottom wall of the box body 1 is provided with an air outlet 3 and a liquid outlet 4, wherein the air inlet 2 is connected to the outlet of a steam generator of a coffee machine, and the air outlet 3 is connected to a steam nozzle or a milk froth generator of the coffee machine.

[0023] The positions of the air inlet 2 and the air outlet 3 are staggered, and an air inlet duct 5 extends from the air inlet 2 into the box body 1, and an air outlet duct 6 extends from the air outlet 3 into the box body 1. The pipe opening of the air outlet duct 6 is higher than the pipe opening of the air inlet duct 5, and an inclined plate 7 is provided on the inner wall of the box body 1 below the pipe opening of the air inlet duct 5. The liquid outlet 4 is located on the bottom wall of the box body 1 within the horizontal projection plane of the inclined plate 7, and a liquid outlet hole 8 is provided in the liquid outlet 4.

[0024] The steam generated by the steam generator enters the box body 1 through the air inlet 2, and the heavier liquid in the steam 1 is deposited at the bottom of the box body 1 and discharged from the liquid outlet 4 through the liquid outlet hole 8; while the remaining lighter steam accumulates in the upper part of the box body 1. Since the pipe opening of the air outlet duct 6 is higher than the pipe opening of the air inlet duct 5, the steam with the liquid removed continuously enters the air outlet duct 6 and is discharged through the air outlet 3, thereby realizing gas-liquid separation and the steam is also dried to a certain extent.

[0025] Since the liquid outlet 4 is located on the bottom wall of the box body 1 within the horizontal projection plane of the inclined plate 7, and the inclined plate 7 is directly below the pipe opening of the air inlet duct 5, the inclined plate 7 blocks the steam entering the box body 1 from directly rushing into the liquid outlet 8, thereby preventing the steam from overflowing from the liquid outlet 4.

[0026] A rubber plug 9 is provided in the liquid outlet 4, and the liquid outlet hole 8 is arranged in the thin-walled part in the middle of the rubber plug 9. The liquid outlet hole 8 also adopts a slit-like small hole structure, thereby realizing the normal outflow of the liquid deposited at the bottom of the box body 1, and increasing the resistance of the steam entering the liquid outlet hole 8, further avoiding the overflow of the steam from the liquid outlet 4.

[0027] In addition, the depression angle range of the inclined plate 7 is 15-45°. Within this angle range, the steam entering the box body 1 can be better guided to avoid the steam spraying directly to the liquid outlet 8, reduce the splashing of liquid at the bottom of the box body 1, and facilitate the liquid on the inclined plate 7 to drip downward.

[0028] The box body 1 is made of plastic, which is easy to manufacture and has good heat resistance and sanitation effects.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
