Foot massaging tub having an operation control device

Abstract

A foot massaging tub includes a main body having a bottom provided with a drain hole, a draining pipe mounted on the main body and connected to the drain hole, a pumping motor mounted on the main body and connected to the draining pipe, and an operation control device mounted on the main body and including a controller, a power output unit, and a sensor. Thus, the sensor detects if liquid enters the draining pipe and sends a signal to the controller which controls the power output unit to operate, so as to open or close the pumping motor automatically.

What is claimed is:  
     
         1 . A foot massaging tub, comprising: 
 a main body having a bottom provided with a drain hole;    a draining pipe mounted on the main body and connected to the drain hole;    a pumping motor mounted on the main body and connected to the draining pipe; and    an operation control device mounted on the main body and including a controller, a power output unit, and a sensor, wherein:    the controller is mounted in the main body;    the power output unit has a first end connected to an electric wire of the pumping motor and a second end connected to the controller; and    the sensor is mounted in the main body and is connected to the controller.    
     
     
         2 . The foot massaging tub in accordance with  claim 1 , wherein the sensor detects if liquid enters the draining pipe and sends a signal to the controller which controls the power output unit to operate, so as to open or close the pumping motor automatically.  
     
     
         3 . The foot massaging tub in accordance with  claim 1 , wherein the sensor is mounted on an outer periphery of the draining pipe.  
     
     
         4 . The foot massaging tub in accordance with  claim 1 , wherein the operation control device further includes an indication unit mounted on and protruded outward from the main body to indicate the working condition of the pumping motor.  
     
     
         5 . The foot massaging tub in accordance with  claim 4 , wherein the indication unit is connected to the controller.  
     
     
         6 . The foot massaging tub in accordance with  claim 4 , wherein the indication unit consists of a light emitting diode.  
     
     
         7 . The foot massaging tub in accordance with  claim 1 , wherein the operation control device further includes a power input unit having a first end connected to a power supply and a second end connected to the controller.
