Summary:PROBLEM TO BE SOLVED: To provide indoor equipment of an air conditioner which can prevent failure of a detection sensor while securing detection accuracy of refrigerant gas leakage.SOLUTION: Floor type indoor equipment of an air conditioner includes an indoor heat exchanger having a refrigerant pipeline 39 in which a refrigerant having specific gravity larger than air flows; a lower base 23 which is installed below the indoor heat exchanger and serves as a foundation of a housing; and a detection sensor 50 which detects refrigerant leakage. The lower base 23 includes: a recessed part 231 formed with an inclined surface 231a which receives the leaking refrigerant; and a side wall 232 enclosing an outer periphery of the recessed part 231. The inclined surface 231a contacts with an inner surface of the side wall 232 and is formed so that a height gradually lowers relative to a horizontal surface. The detection sensor 50 is installed at a position below the inclined surface 231a. The position below the inclined surface 231a is a position spaced a predetermined distance apart from a position immediately below a pipeline connection part 40.SELECTED DRAWING: Figure 4 【課題】冷媒ガス漏洩の検出精度を確保しつつ、検知センサの不具合を防止できる空気調和機の室内機を提供する。【解決手段】空気調和機の床置型室内機は、空気よりも比重が大きな冷媒が通流する冷媒配管３９を有する室内熱交換器と、室内熱交換器の下方に設置され、筺体の土台となる下ベース２３と、冷媒の漏洩を検知する検知センサ５０と、を備える。下ベース２３は、漏洩した冷媒を受ける傾斜面２３１ａが形成された凹部２３１と、凹部２３１の外周を囲む側壁２３２と、を備える。傾斜面２３１ａは、側壁２３２の内面に接して、水平面に対して高さが徐々に低くなるように形成されている。検知センサ５０は、傾斜面２３１ａの下方の位置に設置されている。傾斜面２３１ａの下方の位置は、配管接続部４０の真下から所定距離離れた位置である。【選択図】図４
