On housing 310 left-hand end, be provided with the side plate 330 of the worn-out housing of screening 310 inside of adopting disc structure.Side at side plate 330 has possessed from the enclosure interior perforation, therefore makes the refrigerant that flow into housing 310 inside be assigned to the distribution openings 332 of capillary 400 inside.Therefore, the diameter of distribution openings 332 and quantity should be corresponding with capillary 400.And therefore capillary 400 keeps the state that is inserted in distribution openings 332 in the outer peripheral face welding of distribution openings 332, meanwhile, prevents the leakage of refrigerant.

But existing knockout is in actual moving process, owing to can not always guarantee vertical placement, cause indoor set in the running, cause the phenomenon that shunting is uneven, gas-liquid separation occurs, make each temperature capillaceous difference occur, thereby cause in the process of heating local temperature very low, thereby occur freezing, the defrosting phenomenon influences the normal operation of machine.

Summary of the invention

In view of this, the purpose of this invention is to provide a kind of diffusion injecting type knockout, it can evenly shunt the reduction noise, has improved the total quality of wall-hanging air conditioner, strengthens the use experience of user to air-conditioner.

For achieving the above object, the technical solution used in the present invention is:

A kind of knockout, it comprises housing, the side plate of closure casing, run through side plate and be used to connect distribution openings capillaceous, and the refrigerant pipe that is connected with housing, it is characterized in that: described refrigerant pipe stretches to enclosure interior and extends a segment distance, and its end sealing, is formed with spray-hole on the refrigerant pipe sidewall that enclosure interior contains.

Described refrigerant duct occlusion end is spherical.

Be formed with spray-hole symmetrically on the described refrigerant duct occlusion end.

The outer surface along the refrigerant pipe of described spray-hole is the annular distribution that parallels.

The spray-hole of adjacent ring is crisscross arranged.

Technique effect of the present invention is: knockout of the present invention adopts diffusion injecting type structure, when the refrigerant of gas-liquid coexistence sprays from spray-hole, pressure reduces, and the temporary gasification of liquid refrigerants is to be shunted to each capillary, again can be because of the rising of pressure, and return to original gas-liquid coexisting state, and really reached the uniform purpose of shunting, make and realize balance between each capillary, and this structure also can doublely play the effect that reduces noise, has increased user satisfaction.
