Fan having cold air function
View Patent ↗The present invention relates to a fan with a cold air function which, through supply of liquid oxygen (LOX), has a strong cold air function and at the same time provides an air cleaning effect by supplying oxygen. A fan including a base part ( 10 ) equipped with a plurality of buttons ( 11 ), a main body part ( 20 ) installed on the top of the base part ( 10 ), a motor part ( 30 ), rotary blades ( 40 ) coupled to a motor shaft at the front of the motor part ( 30 ), and a protection net ( 50 ) installed to surround the rotor blades ( 40 ), the fan comprises: a mounting part ( 60 ) in which a liquid oxygen (LOX) charge canister ( 62 ) is removably mounted; an opening and closing controller ( 63 ) for controlling the output amount of an oxygen gas discharged from the charge canister ( 62 ) mounted in the mounting part ( 60 ); and a discharge pipe ( 64 ) which is connected to the opening and closing controller ( 63 ) and configured in such a manner that the discharged oxygen gas is diffused through the rotary blades ( 40 ) to the front.
1. A fan having a cold air function, comprising:
a base with a plurality of buttons disposed thereon, wherein the plurality of buttons include a switch having at least a plurality of wind speed selection buttons, a cold air selection button, and a setting button;
a main body mounted on top of the base;
a motor mounted on top of the main body and having a motor driver to rotate the motor;
rotary blades coupled to a motor shaft located on a front surface of the motor, and a protection net adapted to surround the rotary blades therewith;
a mounting for detachably mounting a liquid oxygen (LOX) charge canister thereinto;
an opening and closing controller to control an amount of cold oxygen gas discharged from the LOX charge canister, wherein the opening and closing controller includes a control circuit having an output adjuster to control the opening and closing controller to control the amount of oxygen gas outputted;
a discharge pipe connected to the opening and closing controller to allow the discharged cold oxygen gas to be emitted forwardly through the rotary blades, and
a controller to set a cold air function according to the button input of the switch, to output a motor driving signal corresponding to a wind speed selection inputted upon the selection of the cold air function to the motor driver, and to output a control signal to the output adjuster so that an amount of the cold oxygen gas corresponding to the wind speed selected is supplied.
2. The fan according to claim 1 , wherein the LOX charge canister contains liquid oxygen compressed to a temperature of −183° C. or lower.
3. The fan according to claim 1 , wherein the mounting is located at the interior of the main body.
4. The fan having according to claim 1 , wherein the protection net has a shape of a pipe and comprises a plurality of horizontal net members, a rim net member, and a plurality of discharge holes formed on front sides of the plurality of horizontal net members and the rim net member.
