Embodiment Construction

[0046] Next, embodiments of the drain pump of the present invention will be described with reference to the drawings. figure 1 It is a perspective view of the drainage pump of the embodiment, figure 2 is a side view of the drain pump.

[0047] This drain pump includes a pump unit main body 10 , a motor unit 20 as a “driving unit” constituted by a DC brushless motor or the like, and an upper cover 30 . The pump portion main body 10 has a thin cylindrical pump chamber case 10A and a cylindrical cover case 10B. In the pump chamber case 10A, a suction port 10A1 arranged in the dew pan 40 of the air conditioner, and a discharge port 10A2 to which a discharge pipe not shown is connected are formed. In addition, fitting portions 10A3 are formed at two locations on the outer periphery of the pump chamber case 10A, and the fitting portions 10A3 are engaged with the lower end portion of the lid case 10B, thereby forming the pump chamber case 10A and the lid case 10B. be fixed. In a...

Abstract

The invention provides a draining pump and an air conditioner, and a structure for attaching a bush (1) to a bracket (30A) for reducing the influence of vibration of a motor part (20) is improved, andtwo-color molding and the like are not used. A pump main body (20) and an upper cover (30) are used for clamping and fixing the motor part (20). A bracket (30A) is formed on the outer periphery of the upper cover (30). A C-shaped holding part (30c) is formed at the tip portion of the bracket (30A). A constricted part (13) (a part to be held) of the bush (1) is embeded into the holding portion (30c). The bush (1) is held at the front end portion of the bracket (30A), and is fixed to a unit top plate by a screw (N) via a screw hole (14) of the bush (1). An abutment protrusion (2) is arranged onthe upper surface of the upper cover (30). An elastic leg seat (22) which stands against a projection (2) contacts with the unit top plate (50).

Description

technical field [0001] The present invention relates to a drain pump for draining water retained in a dew pan of an air conditioner, and an air conditioner provided with the drain pump. Background technique [0002] Conventionally, as a drain pump for an air conditioner, there is a drain pump disclosed in, for example, Japanese Patent Application Laid-Open No. 2013-15097 (Patent Document 1). In this type of drain pump, the impeller of the pump chamber is rotated by the motor, so that the water in the dew pan is sucked from the suction port in the lower part of the pump chamber, and the water is discharged to the outside from the discharge port in the side part of the pump chamber. In addition, the drain pump is fixed to the unit top plate inside the indoor unit of the air conditioner by the unit mounting part (bracket) of the casing provided on the upper part of the motor part. [0003] Therefore, there is a problem that the vibration generated from the motor is transmitted...
