[0043] Embodiment 1

[0044] The present embodiment provides a condenser pipe, as shown in Figure 1 and Figure 2 comprises:

[0045] a water collecting base 1;

[0046] an outer shell 2 arranged on the water collecting base 1, a steam inlet 3 is arranged on the water collecting base 1 or the outer shell 2 in front of the steam flow direction, a steam outlet 4 is arranged on the outer shell 2, and a heat exchange cavity is formed between the water collecting base 1 and the outer shell 2; the outer shell 2 itself can be arranged in a cylindrical manner, or can be made of other regular or irregular shapes, as long as it can form a stable space with the water collecting base 1;

[0047] Specifically, in the present embodiment, an inner thread is arranged on the inner wall of the water collecting base 1, and an outer thread is arranged on the outer wall of the outer shell 2, and the detachable connection between the water collecting base 1 and the outer shell 2 is realized through the cooperation of the inner thread and the outer thread;

[0048] a heat exchange pipe arranged in the heat exchange cavity, the heat exchange pipe comprising:

[0049] a center column 6 extending in the height direction of the heat exchange cavity;

[0050] a spiral heat exchange fin 5 arranged on the outer wall of the center column 6, the steam entering the heat exchange cavity through the steam inlet 3 is adapted to pass through the spiral heat exchange fin 5 and flow out from the steam outlet 4. The spiral heat exchange fin 5 itself is made of a material with good thermal conductivity, which can be a metal material, or a ceramic material or a quartz material;

As a preferred embodiment, the water collecting base 1 is provided with a condensed water outlet 9, and the condensed water directly flows back to the steaming device through the condensed water outlet 9, thereby ensuring the normal condensing capacity of the condensing pipe.

[0059] In the embodiment, the position of the condensed water outlet 9 is not limited, which can be provided on the bottom wall of the water collecting base 1 or on the side wall of the water collecting base 1. As a preferred embodiment, the water collecting base 1 is provided in a central recessed manner, and the condensed water outlet 9 is provided at the central part of the water collecting base 1, thereby ensuring that the condensed water is concentrated and stored and flows out to the outside.

By providing the liquid guide pipe and the condensing pipe, when the condensing pipe inside produces condensed water, the condensed water will flow along the liquid guide pipe away from the cooking position, thereby avoiding directly dropping on the food material on the cooking position, thereby avoiding the food softening and deforming.

[0065] Specifically, the liquid guide pipe can extend towards the bottom wall of the shell 10, or directly extend to the outside of the shell 10. The liquid guide pipe itself is made of high-temperature resistant material, which can be a metal pipe or a flexible pipe, and is not limited in the embodiment.

[0066] The steam equipment provided by the embodiment can be a steam oven, a steam and baking integrated machine, etc. As long as the equipment can generate steam inside, it belongs to the steam equipment provided by the embodiment.

[0067] In the embodiment, the shell 10 is provided with a cold air hole 11 on one side of the condenser pipe mounting hole, and the heat conduction part 7 is arranged on the cold air hole 11. By arranging the cold air hole 11, the heat conduction part 7 is stably connected to the shell 10, and the cold air outside continuously acts on the spiral heat exchange fins 5 of the condenser pipe, thereby ensuring the condensation performance of the whole steam equipment.

[0068] In the embodiment, in order to ensure that the cold air outside continuously acts on the heat conduction part 7, a fan wheel 12 is arranged on the shell 10 above the cold air hole 11, and the wind generated by the fan wheel 12 is suitable for acting on the heat conduction part 7.

[0070] Specifically, as shown in Figure 3 The high-temperature steam b and the air d enter the heat dissipation cavity at the same time, and in the heat dissipation cavity, the air d dissipates heat to the spiral heat exchange fins, at this time, the temperature of the spiral heat exchange fins will be reduced, the high-temperature steam b will be converted into condensed water a, and discharged from the water collecting base to the outside. At the same time, the low-temperature steam c after cooling will flow out from the steam outlet, at this time, the water content in the steam will be greatly reduced.

[0071] Obviously, the above embodiments are only examples for clearly illustrating, and not limiting the embodiments. For those skilled in the art, on the basis of the above description, other different forms of changes or variations can also be made.
