Definitions

  • the invention relates to a floor assembly for a device for drying laundry, having at least one heat pump with heat exchangers that can be thermally coupled to a process air system of the device and at least one heat exchanger housing in which the heat exchangers are arranged, the heat exchanger housing having at least one installation floor on which the heat exchangers are placed and has at least one cover part covering the heat exchangers on a side facing away from the installation floor.
  • the invention also relates to a device for drying laundry.
  • Devices for drying laundry are known in a variety of configurations.
  • devices for drying laundry which have a closed process air system with a drying chamber receiving laundry to be dried and a heat pump thermally coupled to the process air system to recover heat from the process air circulating in the process air system.
  • the heat pump forms part of a floor assembly of the device which is located on the floor below the drying chamber and through which a section of the process air system runs.
  • a heat pump has two heat exchangers thermally coupled to the process air system, namely a heat exchanger (evaporator) that cools and dehumidifies the process air exiting the drying chamber and a heat exchanger (condenser) that heats the process air to be supplied to the drying chamber.
  • the heat exchangers are arranged in a heat exchanger housing of the floor assembly, through which the process air is passed and which thus forms a section of the process air system.
  • a conventional heat exchanger housing has a mounting base on which the heat exchangers are set up, and side walls laterally surrounding the heat exchangers.
  • the conventional heat exchanger housing has a plastic cover which is arranged on a side of the heat exchanger facing away from the installation base and is connected to the side walls.
  • Refrigerant lines of a refrigerant circuit of the heat pump are usually passed through one of the side walls to be able to connect the heat exchanger to a compressor arranged outside the heat exchanger housing and to a correspondingly arranged expansion unit of the heat pump.
  • the corresponding bushings on the side wall are conventionally sealed off from the respective refrigerant line by means of a seal in each case.
  • Such a conventional heat exchanger housing is usually air-permeable to ambient air.
  • ambient air can enter the heat exchanger housing and mix with the process air flowing therein and / or flow past the heat exchangers.
  • the process air passes through the so-called pressure transition point, which ensures that there is a negative pressure in the area of the condenser, through which the ambient air is sucked into the heat exchanger housing. Since the heat exchanger and the housing components of the heat exchanger housing have different structural tolerances, there can be gaps between the housing components and the heat exchangers and bypass flows arise within the heat exchanger housing.
  • a heat pump contains a refrigerant that circulates in a closed circuit and is cyclically evaporated while absorbing heat and is condensed while releasing heat.
  • the evaporation of the refrigerant takes place mainly in the evaporator of the heat pump.
  • the refrigerant flows into the evaporator as a mixture of liquid and gas.
  • the refrigerant then reaches a compressor in the heat pump as a gas, where it is compressed.
  • the compressor is also the drive that drives the refrigerant through the closed circuit.
  • the compressed refrigerant arrives from the compressor to the condenser of the heat pump, where it is liquefied while releasing heat.
  • the liquefied refrigerant passes into an expansion device, in particular a valve, a diaphragm or a capillary, in which the internal pressure of the refrigerant is reduced and in which the refrigerant is already partially converted back into gas.
  • an expansion device in particular a valve, a diaphragm or a capillary, in which the internal pressure of the refrigerant is reduced and in which the refrigerant is already partially converted back into gas.
  • the resulting mixture of liquid and gas is returned to the evaporator.

  • the heat pump dryer has a grid which is arranged between the heat exchangers of the heat pump so that the process air flowing through the heat exchanger used as an evaporator is at least partially guided to the heat exchanger designed as a condenser.
  • One object of the invention is to prevent ambient air from being mixed with process air flowing through a floor pan of a device for drying laundry and to prevent bypass process air flows from forming within a heat exchanger housing of the floor pan.

  • the duct section of the process air system between the heat exchangers is sealed airtight at least on its top side facing the cover part and laterally, which reliably prevents ambient air from penetrating the top or the side of the duct section and mixing with the process air flowing in the duct section.
  • the inventive sealing of the duct section of the process air system reliably prevents process air exiting the evaporator from exiting upwards and / or to the side of the duct section and flowing past the condenser as a bypass process air flow, which increases the drying effectiveness and energy efficiency accordingly equipped device for drying laundry.
  • the heat pump can be of conventional design and, in addition to the heat exchangers, have a compressor for compressing a refrigerant of the heat pump and an expansion unit for expanding the refrigerant.
  • the compressor and the expansion unit are preferably arranged outside the heat exchanger housing and are connected to the heat exchangers via refrigerant lines of the heat pump.
  • the heat exchanger housing has the installation base and the cover part.
  • the inventive sealing of the duct section of the process air system can in particular prevent process air flowing out of the evaporator from exiting the duct section and flowing laterally past the condenser, so that conventional side walls that are arranged laterally on the condenser with respect to a flow direction of the process air are Floor pan according to the invention are not required.
  • the heat exchanger housing can be designed to be open at least on one side of the condenser. This reduces the cost of materials for producing the floor pan according to the invention.

The cover part can then be installed, the projections being pressed progressively between the heat exchangers, whereby the heat exchangers are progressively pushed away from each other and thereby moved in opposite directions on the installation floor until the heat exchangers come into at least indirect contact with the respective wall elements. Pressing in the projections between the heat exchangers further into their end positions causes the heat exchangers are pressed against the respective wall elements, whereby the heat exchangers are clamped between the projections of the respective wall elements.
