Nozzle for cleaner

Abstract

A nozzle for a cleaner has a nozzle housing having a suction flow path that extends in a front and rear direction so that air containing dust is sucked. The nozzle further includes a first rotation plate and a second rotation plate, a water tank provided in the nozzle housing, the water tank configured to store water to be supplied to the first and second rotation plates, and a water supply flow path formed in the nozzle housing to supply water from the water tank to the first and second rotation plates. The water tank has a discharge port to which the water supply flow path is connected. The water supply flow path includes a water pump. The discharge port and the water pump are arranged to be spaced apart from each other in a same side area.

What is claimed is: 
     
         1 . A nozzle for a cleaner comprising:
 a nozzle housing including:
 a connection pipe connected to the cleaner having a suction motor formed in a rear central portion; and 
 a suction flow path that extends in a front and rear direction so that air containing dust is sucked; 
   a first rotation plate and a second rotation plate arranged to be spaced apart in a left and right direction below the nozzle housing and each capable of attaching a mop;   a water tank provided in the nozzle housing, the water tank configured to store water to be supplied to the first and second rotation plates; and   a water supply flow path formed in the nozzle housing to supply water from the water tank to the first and second rotation plates,   wherein the water tank has a single discharge port to which the water supply flow path is connected,   wherein the water supply flow path includes:
 a first supply pipe coupled to the discharge port to introduce water into the water tank; 
 a water pump connected to an outlet of the first supply pipe; 
 a second supply pipe connected to the water pump, the second supply pipe being configured to introduce water discharged by the water pump; and 
 a connector connected to the second supply pipe to guide water to each of the first and second rotation plates, 
   wherein the single discharge port and the water pump are arranged to be spaced apart from each other in a same side area from the suction flow path extending in the front and rear direction.   
     
     
         2 . The nozzle for a cleaner of  claim 1 , further comprising a flow path forming portion that is arranged inside the nozzle housing and extends from a front end of the nozzle housing to the connection pipe to form the suction flow path in which the air containing dust flows to the connection pipe. 
     
     
         3 . The nozzle for a cleaner of  claim 2 , wherein an internal space of the nozzle housing is defined as a lateral space divided left-side area and right-side area with the flow path forming portion as the center, and
 wherein the single discharge port and the water pump are arranged so as to be spaced apart from each other on one side of the lateral space.   
     
     
         4 . The nozzle for a cleaner of  claim 3 , further comprising a control board that is configured to operate by receiving power is arranged on another side of the lateral space. 
     
     
         5 . The nozzle for a cleaner of  claim 4 , wherein the control board is further configured to control rotation of the first and second rotation plates, the control board being disposed in an opposite area, and
 wherein the opposite area is defined as a side area opposite to the single discharge port centered on the suction flow path extending in the front and rear direction.   
     
     
         6 . The nozzle for a cleaner of  claim 5 , wherein the single discharge port is spaced apart to the left around the suction flow path extending in the front and rear direction, and
 wherein the control board is spaced apart to the right around the suction flow path extending in the front and rear direction.   
     
     
         7 . The nozzle for a cleaner of  claim 2 , further comprising a driving device that is arranged spaced apart from the flow path forming portion in the left and right direction so as to be spatially separated from the flow path forming portion, the driving device being configured to rotate the first rotation plate and the second rotation plate. 
     
     
         8 . The nozzle for a cleaner of  claim 7 , wherein the water supply flow path further includes:
 a first branch tube configured to supply water from the connector to the first rotation plate; and   a second branch tube configured to supply water from the connector to the second rotation plate.   
     
     
         9 . The nozzle for a cleaner of  claim 8 , wherein the water supply flow path further includes:
 a first spray nozzle provided in the first branch tube to supply water toward an upper surface of the first rotation plate; and   a second spray nozzle provided in the second branch tube to supply water toward an upper surface of the second rotation plate.   
     
     
         10 . The nozzle for a cleaner of  claim 1 , wherein the single discharge port is disposed closer to a front end of the nozzle housing than to a rear end of the nozzle housing. 
     
     
         11 . The nozzle for a cleaner of  claim 1 , wherein the connector is positioned to overlap above the suction flow path extending in the front and rear direction. 
     
     
         12 . The nozzle for a cleaner of  claims 1 , wherein the suction flow path further has a left-right flow path extending in the left and right direction along a front end of the nozzle housing, and
 wherein the suction flow path extending in the front and rear direction extends rearward from a central portion of the left-right flow path.   
     
     
         13 . The nozzle for a cleaner of  claim 1 , wherein at least a portion of the water tank is arranged to overlap in a vertical direction with the suction flow path extending in the front and rear direction. 
     
     
         14 . The nozzle for a cleaner of  claim 1 , wherein the water tank has a pair of chambers that are symmetrical in the left and right direction around the suction flow path extending in the front and rear direction. 
     
     
         15 . The nozzle for a cleaner of  claim 1 , wherein the water supply flow path further includes a valve operation member configured to control the supply of water from the single discharge port of the water tank, and
 wherein the valve operation member is connected to the first supply pipe and is arranged to face the single discharge port in a vertical direction of the nozzle hosing.
