Embodiment Construction

[0035] exist figure 1 In FIG. 1 , a laundry dryer is indicated by reference number 1 , which has a laundry drum 2 for receiving laundry to be dried. The laundry drum 2 is connected to the process air channel 3 of the process air system forming a circuit as a whole, wherein relatively hot, dry process air flows into the laundry drum 2 via the supply air section 3a of the process air channel 3 and The discharge air section 3b which passes through the process air channel 3 then flows out of the laundry drum 2 again as moist, water vapor-enriched process air (after it has absorbed the moisture from the laundry). A corresponding air flow inside the process air channel 3 is generated by a process air fan 4 .

[0036] A heat pump 5 interacting with the process air system of the laundry dryer 1 has a first heat exchanger 6 configured as a condenser and a second heat exchanger 7 configured as an evaporator. Here, the process air in the cooled and dry state, which is conveyed through ...

Abstract

The invention relates to a device assembly formed by arranging a heat exchanger of a heat pump of a laundry dryer on a mounting base. Process air of the laundry dryer flows through the heat exchanger; the mounting base is associated with a bottom assembly of the laundry dryer. An intermediate space is provided between the heat exchangers as viewed in the flow direction of the process air. In the intermediate space, the transition of the channel section of the process air channel formed by the two heat exchangers is laterally delimited by two connecting elements which are vertical, parallel and spaced apart. The connecting elements are connectable to the mounting base and to the upper end cap and each rest against a heat exchanger contact surface. In order to provide a device assembly for sealing a process air channel in an intermediate space, which can be produced by means of a simple and suitable device for mass production, the connecting element is provided with a sealing element over the entire section of the longitudinal edge of the connecting element; a flat contact surface of the heat exchanger placed on the mounting base rests on the sealing element.

Description

technical field [0001] The invention relates to an assembly (Anordnung) comprising a heat exchanger of a heat pump of a laundry dryer, whose process air flow through these heat exchangers, wherein, viewed in the flow direction of the process air, there is an intermediate space between these heat exchangers, in which the process air channel formed by the two heat exchangers The transition of the channel section is bounded laterally by two connecting elements running vertically and parallel and at a distance from one another, wherein these connecting elements are connected or connectable to the mounting base on the one hand and to the mounting base on the other hand. The upper end caps are connected or connectable, and these connection elements each rest on a contact surface of the heat exchanger. Background technique [0002] In order to receive and process the laundry to be dried, the laundry dryer has a rotary laundry drum which is connected to a process air system, wherei...
