first embodiment
[0096]FIGS. 3 to 5 are diagrams showing the motor operated compressor 1000 of the first embodiment provided in the present disclosure.
[0097]FIG. 3 is an exploded perspective view of the inverter module 1200 according to a first embodiment of the present disclosure.
[0098]FIG. 4 is a cross-sectional view of the inverter module 1200 illustrated in FIG. 3. FIG. 5 is a conceptual view of the inverter module 1200 and the main housing 1110 shown in FIG. 3 viewed from the rear side of the motor operated compressor 1000.
[0099]The inverter module 1200 includes an inverter housing 1210, an inverter cover 1220, a circuit component 1230, connectors 1241 and 1242, a printed circuit board (PCB) 1251, a power device 1270, and a heat sink 1280.
[0100]Here, the circuit component 1230 refers to various electrical components such as a capacitor and a switching element mounted on the PCB 1251 to perform an electrical function.
[0101]The communication connector 1242 is partially inserted into the inverter ...
second embodiment
[0131]FIG. 6 is a front view of the inverter cover 2220 according to the present disclosure.
[0132]The plurality of guide protrusions 2223 are formed in a virtual circle about the rotating shaft support portion 2222. The guide protrusions 2223 adjacent to each other among the plurality of guide protrusions 2223 are arranged to be spaced apart from each other at equal intervals from all directions. The all directions refer to the directions of up, down, left, and right about the guide protrusion 2223. According to the guide protrusion 2223 having such a structure, the compression target fluid flowing in through the intake port 2111 may be stably guided to the opposite side of the intake port 2111.
[0133]The rotating shaft support portion 2222 protrudes annularly from the surface of the inverter cover 2220 toward the motor chamber S1, whereby the inner and outer sides of the annular shape are distinguished from each other. At least one hole (see 1222a in FIG. 3) is formed on a side surf...
third embodiment
[0137]FIG. 7 is a front view of an inverter cover 3220 according to the present disclosure.
[0138]Guide protrusions 3223 of the first and second embodiments protrude in a hemispherical shape, whereas a guide protrusion 3223 of the third embodiment may protrude in a shape other than the hemispherical shape. For example, as described below, the guide protrusion 3223 may protrude in a form extending along a straight line or curve.
[0139]The rotating shaft support portion 3222 may be divided into a first guide protrusion 3223a, a second guide protrusion 3223b, a third guide protrusion 3223c, and a fourth guide protrusion 3223d according to a formation position and an extending direction.
[0140]The first guide protrusion 3223a protrudes from the inverter cover 3220 and extends along a virtual circle centered on the rotating shaft support portion 3222. A plurality of first guide protrusions 3223a may be formed on inverter cover 3220. The plurality of first guide protrusions 3223a may be arra...
