## Background
The present invention relates to a dishwasher the sound and heat insulation of which is improved.
In dishwashers, the water received from the mains during washing is directed to the regeneration unit by being passed through the tank called the water receptacle, and to the washing tub from there. The water receptacle is disposed between the washing tub and the side wall of the body. By means of the air break disposed on the water receptacle, the air contained in water is provided to be discharged outside, the water droplets remaining in the water receptacle are drained into the washing tub by means of the water receptacle leakage hole opening to inside of the washing tub.
In the dishwashers, furthermore, a fan suction hole facing to the inside of the washing tub and an air channel with one end connected to the fan suction hole and the other end to the fan are disposed. The air channel is disposed between the washing tub and the side wall of the body.
In the state of the art, the water receptacle is disposed on one side of the body and the air channel on the other side of the body. Problems are encountered in sound and heat insulation since these two components being disposed on two separate side walls of the body prevent the use of felt in the places these components are located. Furthermore, not being able to use felt in the places these components are disposed results in energy losses.
The aim of the present invention is the realization of a dishwasher the sound and heat insulation of which is improved.
The dishwasher realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a water receptacle and an air channel integrated with the water receptacle. The water receptacle provides the water received from the mains to be stored before being delivered to the regeneration unit and the air of water to be broken by the air breaks disposed therein. The air channel provides the vapor aspirated from the washing tub during the drying step to reach the fan and to be discharged outside. The water receptacle and the air channel are disposed between the washing tub and the same side wall such as to be integrated to each other. Accordingly, one of the side walls is provided to remain empty. Thus, the sound and heat insulation of the dishwasher is improved by entirely cladding bitumen and felt on the side wall on which no component is disposed. On the other hand, the energy consumption of the dishwasher is decreased by improving the heat insulation and saving in energy is provided.
The water receptacle and the air channel open into the washing tub by means of a shared hole. The hole not only provides the water leakage occurring in the air break of the water receptacle to be discharged into the washing tub but also allows the vapor in the washing tub to be aspirated by the fan during the drying step. The water receptacle and the air channel functioning by using a shared hole eliminate the need for opening a second hole on the washing tub.
In an embodiment of the present invention, the air channel is attached to the water receptacle by plastic welding. An integrated water receptacle—air channel structure is formed by the water receptacle and the air channel being connected to one another by using an inexpensive and simple method like welding.
In another embodiment of the present invention, the water receptacle and the air channel are produced in integrated form. By means of the integrated production, the problems of leakage that may arise during connecting the water receptacle and the air channel are prevented.
In another embodiment of the present invention, a set is provided in the water receptacle in order to prevent the water drops remaining in the water receptacle that cannot pass into the regeneration unit from passing into the air channel. The set prevents water drops from escaping into the air channel by directing the water drops remaining in the water receptacle towards the water receptacle thus providing them to be discharged into the washing tub by means of the hole. Thus, the fan is protected by preventing passage of water drops through the air channel to the fan.
By means of the present invention, the water receptacle and the air channel are integrated with one another and disposed on only one side wall of the body. The water receptacle and the air channel open into the washing tub by using a shared hole. Consequently, the need for opening separate holes on the washing tub for each one of the water receptacle and the air channel is eliminated. Moreover, by disposing both of the components on the same side wall, the other side wall is provided to be entirely clad by the insulation materials. Consequently, sound and heat insulation of the dishwasher is improved.
