System and method for automatically drawing out a rack in domestic appliances

Abstract

The embodiments herein provide a system for drawing out the racks out of a chamber in a domestic appliance. The system comprises the hooks attached to the respective loop brackets or several steel rods provided with many screws. The hooks are attached to an inner surface of a door of a chamber in a domestic appliance through the brackets that are fixed to the steel rods by the screws or welded to the inner surface of the door. The steel rods are fixed to the door from inside. The hooks are automatically unlatched from the racks when the door is closed. The racks are unlatched due to a pop-up action of the hooks during the closing of the door. The hooks pop-up to the initial position. The hooks pop-up due to a body contact of the hooks with the racks at an upwardly slanting direction.

         2 . The system according to  claim 1 , wherein one or more hooks are welded to the inner surface of the door of the chamber in the domestic appliance. 
     
     
         3 . The system according to  claim 1 , wherein one or more hooks are arranged inside a loop welded to the inner surface of the door of the chamber in the domestic appliance. 
     
     
         4 . The system according to  claim 1 , wherein the domestic appliance is any one of an oven, a dish washer, and wherein the domestic appliance is a front loading type. 
     
     
         5 . The system according to  claim 1 , wherein the one or more racks are automatically drawn out upon opening the door of the chamber. 
     
     
         6 . The system according to  claim 1 , wherein the one or more hooks are made up of metals. 
     
     
         7 . The system according to  claim 1 , wherein the one or more hooks are arranged in any one of a U shape, C shape and inverted U shape. 
     
     
         8 . The system according to  claim 1 , wherein the one or more hooks are fixed at the door at a preset height, and wherein the preset height is equal to or less than a height of a rack. 
     
     
         9 . The system according to  claim 1 , wherein the one or more steel rods is adapted to fix the one or more hooks at a plurality of heights. . 
     
     
         10 . The system according to  claim 1 , wherein the one or more loop brackets are fixed to the steel rods by using one or more screws, and wherein the one or more screws are expanding screws with one or more washers, and wherein the one or more loop brackets are further tightened by screwing the one or more expanding screws through the one or more washers. 
     
     
         11 . A method for automatically drawing out one or more racks out of a chamber in a domestic appliance, the method comprises:
 fixing one or more steel rods on an inner surface of a door of a chamber at a plurality of heights;   fixing and aligning one or more loop brackets with the one or more steel rods;   mounting one or more hooks on the one or more loop brackets;   positioning the one or more hooks to an initial position and wherein two distal ends of the one or more hooks are arranged to face away from the door of the chamber, when the one or more hooks are arranged in the initial position;   latching the one or more hooks with the one or more racks;   drawing out the one or more racks of the chamber by opening the door of the chamber.   
     
     
         12 . The method according to  claim 11 , wherein the one or more hooks are welded to the inner surface of the door of the chamber in the domestic appliance. 
     
     
         13 . The system according to  claim 11 , wherein one or more hooks are arranged inside a loop welded to the inner surface of the door of the chamber in the domestic appliance. 
     
     
         14 . The method according to  claim 11 , wherein the one or more hooks latches on the one or more racks of the enclosure when the one or more hooks fall on the one or more racks due to gravity during an opening of the door. 
     
     
         15 . The method according to  claim 11 , wherein the one or more hooks remain latched on to the one or more racks to draw the one or more racks, when the door of the chamber is opened. 
     
     
         16 . The method according to  claim 11 , wherein the one or more hooks are automatically unlatched from the one or more racks, when the door of the chamber is closed, and wherein the one or more racks are unlatched due to a pop-up action of the one or more hooks during the closing of the door, and wherein the one or more hooks pop-up to the initial position, and wherein the one or more hooks pop-up due to a body contact of the one or more hooks with the one or more racks at an upward slanting direction.
