Motor assembly for steam vacuum cleaner

Abstract

A motor assembly for a steam vacuum cleaner comprises a flow separation packing which is coupled within a motor cooling casing between a cold air intake duct and an air exhaust duct, so as to maximize cooling efficiency of a wet type motor by separating the sucked cold air from the hot air having undergone a cooling operation.

1 . A steam vacuum cleaner comprised of:
 a main body;   a motor assembly coupled to said main body; and   a dust receptacle coupled to said main body, wherein said dust receptacle includes a dust collection bin having a main filter and an auxiliary filter which are separated.   
   
   
       2 . The steam vacuum of  claim 1  wherein the motor assembly is comprised of:
 a motor having a cooling fan and an impeller;   a motor cooling casing having a cold air intake duct through which cool air is drawn by the cooling fan of the motor in order to cool the motor, said air thereby being warmed and then exhausted through an air exhaust duct; and   a packing installed between the air intake duct and the air exhaust duct, for separating the cool air drawn in from the air exhausted from the warm air exhausted through the air exhaust duct.   
   
   
       3 . The steam vacuum of  claim 2 , wherein the motor assembly is further comprised of:
 an impeller casing coupled to the motor cooling casing, designed to enclose and surround the impeller of the motor, said impeller casing having a suction case through which air is drawn in by the impeller when the vacuum is activated and an exhaust port through which the air drawn in by the impeller is exhausted.   
   
   
       4 . The steam vacuum of  claim 2 , wherein the motor cooling casing is transparent. 
   
   
       5 . The steam vacuum of  claim 1 , wherein the motor assembly is coupled to a main body of the steam vacuum cleaner via a motor mount groove. 
   
   
       6 . A steam vacuum cleaner comprised of:
 a main body;   a motor assembly coupled to said main body comprised of a motor cooling casing and an impeller casing which are coupled together in order to form a motor housing for housing a motor having a cooling fan;   a cold air intake duct through which cool air is drawn into the motor housing by the cooling fan of the motor in order to cool the motor,   an air exhaust duct through which the warmed air is expelled from the motor housing after cooling the motor; and   a packing installed between the air intake duct and the air exhaust duct, for separating the cool air drawn in from the air exhausted from the warm air exhausted through the air exhaust duct.   
   
   
       7 . The steam vacuum of  claim 6  wherein the motor is further comprised of:
 an impeller for drawing air into the vacuum through the main body;   an exhaust port through which the air drawn in by the impeller is exhausted.   
   
   
       8 . The steam vacuum of  claim 6  wherein the motor cooling casing is transparent. 
   
   
       9 . The steam vacuum of  claim 6 , wherein the motor assembly is coupled to a main body of the steam vacuum cleaner via a motor mount groove. 
   
   
       10 . A motor assembly for a steam vacuum cleaner, comprising:
 a motor having a cooling fan and an impeller;   a motor cooling casing having a cold air intake duct through which cool air is drawn by the cooling fan of the motor in order to cool the motor, said air thereby being warmed and then exhausted through an air exhaust duct; and   a packing installed between the air intake duct and the air exhaust duct, for separating the cool air drawn in from the air exhausted from the warm air exhausted through the air exhaust duct.   
   
   
       11 . The motor assembly of  claim 10  further comprising:
 an impeller casing coupled to the motor cooling casing, designed to enclose and surround the impeller of the motor, said impeller casing having a suction case through which air is drawn in by the impeller when the vacuum is activated and an exhaust port through which the air drawn in by the impeller is exhausted.   
   
   
       12 . The motor assembly of  claim 10  wherein the motor cooling casing is transparent.
