Main purpose of the present utility model is to provide a kind of and the cold-producing medium efferent duct is vibrated together with compressor and produces fracture and do not produce vibrating noise, and technology is simple when carrying out the welding of cold-producing medium efferent duct, can adopt the mode of continuous oven welding, can not use solder flux, not contaminated filter bottle inside, be suitable for mass-producted cold-producing medium filtering flask.

According to cold-producing medium filtering flask of the present utility model, comprise that one is the cold-producing medium filtering flask of hollow form, top in this cold-producing medium filtering flask, the bottom is formed with opening respectively, from the vertical cold-producing medium input pipe of planting of this cold-producing medium filtering flask top open part, in the place, inner near top of cold-producing medium filtering flask periphery is set and contains porose partition, the top that is positioned at partition is provided with one can be for the filter screen that filters cold-producing medium, be horizontally set with the porose stator of a periphery in the inside of cold-producing medium filtering flask appropriate location, central authorities in stator form a medium pore, in view of the above, from bottom to top plug the cold-producing medium efferent duct of an elongated tubular from the bottom of cold-producing medium filtering flask, the be fixed medium pore of sheet of this cold-producing medium efferent duct is reliably located.

Therefore, the utlity model has following advantage:

(1), carries out cold-producing medium efferent duct 17 when plugging, can guarantee this cold-producing medium efferent duct 17 be positioned at cold-producing medium filtering flask 10 center line symmetric positions on, can prevent that cold-producing medium efferent duct 17 from producing fracture with vibration of compressor, can lower simultaneously because of vibration and listen a noise that produces.

(2), when carrying out cold-producing medium efferent duct 17 welding, because of not needing as conventional case, will it to be clamped welding, get final product, have good manufacturability, be suitable for making in batch the advantage that can increase output and cold-producing medium efferent duct 17 is fixed with stator 14 with anchor clamps.
