A pump housing having a suction chamber and a discharge chamber. A partition wall dividing the suction chamber and the discharge chamber, and having a communication hole formed at a center thereof for allowing the suction chamber to communicate with the discharge chamber. An impact body disposed toward a suction part so as to come into contact with fluid introduced into the suction chamber through the suction passage; and a gas discharge part disposed at an upper portion of a circumferential surface of the housing and communicating with an outside so that gas, separated from the fluid in contact with the impact body, is discharged. The suction part extends in one direction perpendicular to a virtual center line passing through the housing, and the impact body is disposed in a direction opposite to an extending direction of the suction part with respect to the virtual center line.

The present invention relates to an impeller comprising: a shroud having a plurality of spiral upper slot units formed therein; a hub located to face the shroud; and a plurality of blades connected to the hub and inserted into the upper slot units to be coupled to the shroud, wherein the blade includes a body portion formed to be inclined to one side and an upper end portion, which is bent upward from the body portion and has a second concave surface formed in one side and a second convex surface formed on the other side thereof, and the upper slot unit includes an upper slot bottom for forming a space in which the upper end portion is inserted; an upper slot wall divided into a first upper slot wall located at the second concave surface side and a second upper slot wall located at the second convex surface side; and a second inclined surface formed to be inclined from the first upper slot wall so as to face the second concave surface. Thus, the impeller secures the assembling of the blades and has the effect of reducing the possibility of separation of the blades during the high-speed rotation of the impeller, which improves the structural rigidity of the impeller.

Impeller

A fan motor includes: a motor body; a rotary shaft assembly having a rotor and a bearing mounted on a rotary shaft; a stator that surrounds the rotor; an impeller connected to the rotary shaft; and a bracket including a bearing housing portion for receiving the bearing. The bearing housing portion defines a bearing heat dissipating flow path that allows air to be discharged to an outside of the bearing housing portion after passing between the outer surface of the bearing and the bearing housing portion. Air blown from the impeller can absorb heat of the bearing by contacting an outer surface of the bearing while passing through the bearing heat dissipating flow path.

Fan motor

A pump includes a housing which forms a suction chamber and a discharge chamber therein; a suction nozzle which is disposed in one side of the housing, and communicates with the suction chamber; a discharge nozzle which is disposed in the other side of the housing, and communicates with the discharge chamber; a partition wall which partitions the suction chamber and the discharge chamber, and has a communication hole, which communicates the suction chamber and the discharge chamber, that is formed at a central portion; and a plurality of baffles which are disposed inside the suction chamber, and guide fluid introduced through the suction nozzle to the communication hole, wherein the plurality of baffles have different lengths and are separated apart from each other in a circumferential direction in an upper side of the partition wall.

Pump

A fan motor includes: a motor housing; a rotating shaft; a rotor; a stator disposed outside the rotor; an impeller having at least one blade and a hub; and an impeller cover surrounding an outer circumference of the impeller and defining an air suction inlet. The impeller cover includes: a shroud having an inner diameter that expands in an air flow direction; and a non-metallic coating layer coated on an inner circumferential surface of the shroud and having a lower strength than the blade. The non-metallic coating layer includes: a first area having a first thickness; a second area having a second thickness thinner than the first thickness and defining a stepped portion with the first area, thereby minimizing leakage flow caused by the pressure difference from a pressure-side surface to a suction-side surface of the blade to reduce flow path loss and improving efficiency of the fan motor.

Fan motor and method of manufacturing the same

A cooking device according to one embodiment of the present invention includes a cooking chamber configured to provide a space in which food is cooked; a magnetron configured to emit microwaves to the cooking chamber; and a heater configured to emit radiant heat to the cooking chamber, wherein the heater includes a filament, an outer pipe which protects the filament, and a blocking member which is located at an outside of the filament to block the microwaves emitted from the magnetron.

Cooking device

Provided is a cooking appliance. The cooking appliance includes a cavity assembly having a cooking chamber and a door that selectively opens or closes the cooking chamber. The cavity assembly includes a cavity including a plurality of plates defining a top surface, a bottom surface, and both side surfaces of the cooking chamber, wherein a first flange part is disposed on each of front end of the plurality of plates, and a front plate having an entrance opening through which food enters into the cooking chamber, the front plate including a second flange part. The first flange part and the second flange part line-contact each other.

Cooking appliance

A cooking appliance is provided. An operation of a convection motor for operating a convection fan is controlled into various modes according to a cooking temperature and kind of food to be cooked within a cooking chamber. Thus, the food may be more effectively cooked according to the cooking temperature and the kind of food to be cooked.
