Definitions

  • the present invention relates to a heat pump dishwasher wherein the exhaust air is effectively discharged.
  • the use of hot water for the washing process improves the washing performance.
  • the heating of the washing water is performed by means of a heater.
  • the washing water is heated by using the heat pump system. In this case, energy saving is provided compared to conventional dishwashers.
  • the basic components of the heat pump system are compressor, evaporator, condenser, capillary tube and fan.
  • the compressor pressurizes the refrigerant fluid and directs the same to the condenser.
  • the condenser condenses the refrigerant fluid and heats the water which is in direct contact with the condenser.
  • the refrigerant fluid enters the capillary tube. While passing through the capillary tube, the refrigerant fluid loses pressure, expands and enters the evaporator. While passing through the evaporator pipes, the refrigerant fluid draws heat from the ambient air directed thereon, evaporates and cools the surrounding air. The cooled air is blown out of the dishwasher after the evaporator.
  • the ambient air is sucked by means of a fan and passed over the evaporator.
  • the ambient heat is drawn onto the heat pump and used to heat the water.
  • the air is discharged from the cabinet opening to the environment. This opening is provided on the left or right side of the dishwasher.
  • the water intake hose outlet and the water discharge hose outlet of the dishwasher are provided on the left or right side of the dishwasher rear wall. Said hoses move between the rear wall of the dishwasher and the cabinet and come out of the opening.
  • German Patent Application No. DE102019100004 the formation of an air flow path is disclosed, by means of a sealing member which is provided on the air outlet between a heat pump dishwasher and the cabinet, which is provided between the rear wall of the dishwasher and the wall of the cabinet.
  • a dishwasher comprising a base, and a fan and an evaporator provided an air duct extending from said base.
  • the air duct extends from the front of the dishwasher to the back thereof and an air opening is provided at the back side.
  • EP2777474 Another state of the art embodiment is disclosed in the European Patent No. EP2777474 .
  • a heat pump dishwasher is disclosed, wherein the air sucked through the air inlet is guided towards the evaporator by passing through an opening with guiding surfaces and a dust holder.
  • the aim of the present invention is the realization of a heat pump dishwasher wherein the exhaust air is effectively discharged.
  • the dishwasher realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, is a heat pump dishwasher, and comprises a washing tub; an evaporator; a rear wall; an opening which aligns with the part of the rear wall whereon the evaporator is disposed; a water inlet hose; a water discharge hose; and at least one hose holder for each of the water inlet and discharge hoses, fixed onto the rear wall and enabling the water inlet and discharge hoses onto the rear wall such that the opening remains between the water inlet hose and the water discharge hose.
  • the water inlet and discharge hoses are prevented from covering the opening, creating an obstacle in front of the opening and decreasing the air passage cross-sectional area of the opening.
  • the flow rate of the air discharged out of the dishwasher is prevented from being adversely affected, and the efficiency of the heat pump, hence of the dishwasher is increased.
  • the dishwasher comprises the C-shaped hose holder.
  • the hose holder comprises an orifice through which the hose passes, a housing wherein the hose is fitted after passing through the orifice, and a fixing member which is provided on the outside of the housing and which enables the hose holder to be fixed to the rear wall.
  • the hose is passed through the orifice to be fitted into the housing in the hose holder fixed to the rear wall of the dishwasher by means of the fixing member.
  • the two opposite edges of the orifice are stretched, and by means of this stretching, the hose is easily fitted into the housing.
  • the dishwasher comprises at least two hose holders for the water inlet and discharge hoses on the same line, enabling the hoses to extend parallel to each other at the top and bottom of the opening.
  • the dishwasher comprises two channels as the hose holder which are arranged above and below the opening such that the opening remains therebetween, which extend parallel to each other along the rear wall, such that one receives the water inlet hose and the other receives the discharge hose.
  • the dishwasher comprises at least one fixing member in the form of a clamp which passes over the hose in the channel and which is fixed with fixing elements to the rear wall so as to prevent the hose placed in the channel from being detached from the channel.
  • the fixing member is flat.
  • the hose is entirely embedded into the channel.
  • the fixing member is fixed to the rear wall from two ends thereof such that the hose placed into the channel remains therebetween.
  • the fixing member is fixed to the rear wall from a single end thereof while the other end has a jointed structure so as to rotate around the end fixed to the rear wall.
  • the dishwasher comprises hook-and-loop fasteners as the hose holder.
  • one surface of the hook-and-loop fasteners is fixed to the rear wall such that the hose remains therebetween, and after the hose is placed onto the rear wall, the other surface of the hook-and-loop fasteners is brought onto the first surface over the hose to fix the same.
  • the water inlet and discharge hoses are positioned efficiently so as not to block the air outlet such that the air leaving the evaporator has a high flow rate. Since there is no obstacle in front of the cold exhaust air to prevent the same from being discharged through the air outlet, unwanted cooling in the dishwasher is avoided and the efficiency of the heat pump is increased by preventing the drying performance from being adversely affected. Thus, the washing time of the dishwasher is decreased.
  • the dishwasher (1) of the present invention is a heat pump dishwasher (1), and comprises a washing tub; an evaporator; a rear wall (2); an opening (3) which aligns with the part of the rear wall (2) whereon the evaporator is disposed; an inlet hose (4); a discharge hose (5); and at least one hose holder (6) for each of the inlet and discharge hoses (4 and 5), fixed onto the rear wall (2) and enabling the inlet and discharge hoses (4 and 5) onto the rear wall (2) such that the opening (3) remains between the inlet hose and the discharge hose (4 and 5).
  • the inlet and discharge hoses (4 and 5) are prevented from covering the opening (3), creating an obstacle in front of the opening (3) and decreasing the air passage cross-sectional area of the opening (3).
  • the flow rate of the air discharged out of the dishwasher (1) is prevented from being adversely affected, and the efficiency of the heat pump, hence of the dishwasher (1) is increased.
  • the dishwasher (1) comprises the C-shaped hose holder (6).
  • the hose holder (6) comprises an orifice (7) through which the inlet and discharge hoses (4 and 5) pass, a housing (8) wherein the inlet and discharge hoses (4 and 5) are fitted after passing through the orifice (7), and a base (9) which is positioned outside the housing (8) and which enables the hose holder (6) to be fixed to the rear wall (2).
  • the inlet and discharge hoses (4 and 5) are passed through the orifice (7) to be fitted into the housing (8) in the hose holder (6) fixed to the rear wall (2) of the dishwasher (1) by means of the base (9).
  • the inlet and discharge hoses (4 and 5) pass through the orifice (7), the two opposite edges of the orifice (7) are stretched, and by means of this stretching, the inlet and discharge hoses (4 and 5) are easily fitted into the housing (8).
  • the orifice (7) moves back and returns to the initial position, and the inlet and discharge hoses (4 and 5) fitted into the housing (8) are prevented from being detached from the housing (8) by themselves.
  • the dishwasher (1) comprises at least two, preferably three hose holders (6) for each of the inlet hose (4) and the discharge hose (5) on the same line, enabling the inlet and discharge hoses (4 and 5) to extend parallel to each other at the top and bottom of the opening (3) ( Figure 1 and Figure 2 ).
