Description

Technical Field

[0001] The utility model relates to the field of coffee machines, and particularly relates to a steam cooling structure of a coffee machine. Background Art

[0002] After making coffee beverages using a coffee machine each time, a part of water vapor remains in the pipeline inside the coffee machine. Since the boiler inside the coffee machine is always at a relatively high temperature, the water will be heated to generate steam, increasing the pressure inside the system. In order not to affect the next use, the internal pressure must be discharged. The existing treatment structure is that a steam buffer cooling device is installed inside the machine and then connected to a water storage tray through a pipeline. However, after such steam passes through the buffer cooling device and directly flows into the water storage tray, there will still be a part that enters the water storage tray and diffuses everywhere, affecting the overall performance and service life of the machine.

As Figures 1-3 shown, it includes a waste water tray 1 and a cooling box 2; a waste water cavity 11 is formed by inward depression on the surface of the waste water tray 1; the cooling box 2 is fixedly installed inside the waste water cavity 11; a hollow cooling cavity 21 is inside the cooling box 2; a liquid injection channel 22 communicating with the cooling cavity 21 is formed by inward depression on the upper surface of the cooling box 2 for pre-injecting cooling liquid; the liquid injection channel 22 abuts against the inner bottom of the cooling cavity 21 and is spaced from the inner bottom of the cooling cavity 21; a steam inlet 23 is also provided on the cooling box 2; an overflow hole 29 is opened beside the cooling box 2; by arranging the cooling box 2 in the waste water tray 1, steam enters the cooling cavity 21 from the steam inlet 23 and directly contacts the pre-cooling liquid, so that the steam is efficiently and quickly condensed into water. The condensed water can also be used as the cooling liquid to cool the subsequent steam, and the overflow hole 29 is provided so that the condensed water can flow into the waste water tray 1 through the overflow hole 29. In this embodiment, the position of the overflow hole 29 is higher than the lowest point of the liquid injection channel 22, so as to prevent steam from directly discharging from the liquid injection channel 22.

Preferably, the positioning block 12 is L-shaped.

[0023] Preferably, the steam inlet 23 is close to the inner bottom of the cooling chamber 21 and is spaced from the inner bottom of the cooling chamber 21, so that the steam inlet 23 is located below the coolant liquid, so that the steam directly contacts the cooling liquid after entering the cooling chamber 21 through the steam inlet 23.
