ELBOW SHEATH AND AIR CONDITIONER AND HEAT PUMP WATER PUMP HAVING SAME

摘要

Disclosed are an elbow sheath, and an air conditioner and a heat pump water heater having same. The elbow sheath comprises: a first end (12) of the elbow sheath which has a receiving portion (20) configured to receive an elbow assembly, and a second end (10) which is opposite to the first end (12) of the elbow sheath and has an inwardly recessed portion (101). The inwardly recessed portion (101) is provided with a through hole (13). The elbow sheath effectively solves the technical problem that the existing elbow sheath has a poor protective effect on the elbow assembly, and helps to solve the technical problem that the copper pipe parts and small elbow parts are apt to collapse and be deformed.
