Description
Technical Field
The present invention relates to a method for manufacturing a laundry drying appliance with a door fluff screen holder. The invention also relates to a laundry drying appliance thus manufactured. The invention is particularly advantageously applicable to a domestic laundry dryer with a heat pump.
Background
Laundry drying appliances are known which have an internally closed process air channel with at least one heat exchanger (in the following not limited to the generic term "first heat exchanger") and serve for cooling the process air. The water vapor in the process air which has previously flowed out of the laundry drum as moist process air, which has arrived there, condenses on the cold surfaces of the first heat exchanger and then falls off there in the form of drops as condensate water. The wet process air discharged by the laundry drum also contains hairs, fluff or the like, which may partly deposit on the wet first heat exchanger and thereby reduce its efficiency. The dripping or falling condensed water may also contain fluff, hair, and the like.
In order to reduce the amount of fluff, hairs or the like reaching the first heat exchanger, it is known to provide a fluff screen (hereinafter not limited to generically referred to as "door fluff screen") in a process air channel between the laundry drum and the first heat exchanger, the door fluff screen (T ü rflussenb) being insertable, for example, removably into a seat (hereinafter not limited to generically referred to as "door fluff screen seat"), the door fluff screen seat realizing the reception of the door fluff screen in a receiving space which departs from a feed opening for the laundry drum and which extends downwards in the process air channel like a well as a 'fluff screen well', the door fluff screen being insertable by being inserted from above when the feed opening is open, fluff, hairs or the like being blocked by the door fluff screen directly at the rear portion of the discharge from the laundry drum.
It is also known to use a fluff screen fixedly arranged in the process air channel instead of the fluff screen located in the door fluff screen holder. In order to prevent the fluff screen from becoming clogged, it is associated with a cleaning device, by means of which pressurized water can be supplied to the fluff screen for cleaning the fluff screen.
It is also known to collect the condensate water dripping from the first heat exchanger, still containing hair, fluff or the like, in a fluff collecting container ("fluff trap"). The lint trap has a through opening for passing through condensed water dripping from the first heat exchanger on an upper side and a drain opening for draining the condensed water on a lower side. A fluff screen is attached before the discharge opening for catching hairs, fluff or the like. The lint picker is removable and can be cleaned by the user, for example after opening the lid.
It is also known to clean the first heat exchanger with pressurized water by means of a cleaning device. For this purpose, a high-level water tank can be present, which is filled with the condensate that is pumped up and can discharge this water into the downpipe abruptly by opening the valve. The water falling in the downpipe is sprayed or sprinkled onto the first heat exchanger by means of a water distributor (also referred to as "diffuser"), such as a venturi nozzle, present on the lower tip of the downpipe. The water distributor can be configured as a wall element of the process air channel, which wall element is located above the first heat exchanger.
A disadvantage of these known laundry drying appliances is that the development and manufacturing costs for different filtering and/or cleaning variants of otherwise very similar laundry drying appliances are high.
Disclosure of Invention
The object of the present invention is to overcome at least partially the disadvantages of the prior art and in particular to provide a possibility for simplifying the development and/or manufacture of laundry drying appliances with different filtering and/or cleaning variants.
This object is achieved according to the features of the independent claims. Preferred embodiments can be derived in particular from the dependent claims as well as from the subsequent description and the drawings.
This object is accordingly achieved by a method for producing a laundry drying appliance, in which method an element or assembly (hereinafter not limited to the generic term "first element") is inserted into a door fluff screen holder. The pre-given or standardized mechanical port of the door fluff screen seat comprises in particular a screen surface in laundry contact and a fluff screen well with its sealing system. The door lint sieve holder can in particular originate from a feed opening for a laundry drum.
The second element (hereinafter not limited to being generically also referred to as "diffuser insert") is inserted into the seat (hereinafter not limited to being generically referred to as "diffuser seat"). The diffuser seat is located above the first heat exchanger and in front of the first heat exchanger (with reference to the flow of process air). The diffuser seat can be located in particular in a wall or a wall opening of the process air channel. The at least one predefined port of the diffuser seat may be an edge of the wall opening.
A third element is inserted into a third seat (hereinafter not limited to generically referred to as an "under-cladding seat") at least partially below the first heat exchanger. The predefined mechanical ports of the lower deck mount may include: a transition to a lid (see below), a guide element in the bottom basin or in the bottom of the laundry drying appliance. The third element may in particular fill or occupy a space area under the first exchanger.
A fourth element in the form of a front side cover (also referred to as "gripping element" or "service cover device") is inserted into a fourth seat (in the following not limited to the generic term "cover seat") which is located as a flow technology for the process air channel in the front side wall region behind the door fluff screen seat and in front of the first heat exchanger. The predetermined mechanical port of the cover seat can have or be, for example, a sealing port to the bottom component or to the bottom of the laundry drying appliance and/or a transition to the third element.
The first to fourth elements are selected from a respective first to fourth group, wherein each group has a plurality of selectable first, second, third or fourth elements.
A set of a plurality of elements is configured for insertion into its respective seat and can therefore be inserted into the same seat. That is, they are provided as replaceably mounted components without the need for adjustment of the seat.
The plurality of elements of each group are configured to be functionally different.
The method has the following advantages: by selecting the respective first to fourth elements, the laundry drying appliance can be constructed modularly or according to a modular system. In this way, the laundry drying appliance can be designed particularly simply and can also be produced simply. In particular, a reduction in the development costs for the derivation of device variants with different functions is achieved, in which only small components, i.e. the first to fourth elements, are to be redeveloped. Thus, a laundry drying appliance which is otherwise substantially identically constructed can be varied in function in a simple manner by inserting said element into a seat having a predefined mechanical port. That is to say that a basic mechanical manufacture that remains the same is achieved for the entire appliance.
The elements are thus designed such that they are adapted to their seats or to the attached mechanical ports. Still further minor adjustments may be necessary, such as adjusting menu controls.
One improvement scheme is as follows: the laundry drying appliance is a household appliance. The laundry drying appliance may be a stand-alone laundry dryer or a laundry dryer.
Still another improvement is: the laundry drying appliance has a heat pump. The first heat exchanger may then correspond in particular to an evaporator of the heat pump.
There is also an improvement: a heating device for heating the process air is provided between the first heat exchanger and the laundry drum in the flow direction. The heating device may be implemented as a second heat exchanger. The second heat exchanger may in particular correspond to a condenser of the heat pump.
The laundry drying appliance may also have a ventilation device for rotating the process air in the process air channel.
In addition, an improved scheme is as follows: the screen has at least one screen coating and/or at least one filter coating for separating fluff, hairs, etc. from the process air and/or from the water, in particular from the condensate water. In this case, the sieve layer can be provided more for separating coarser components from the process air, and the filter layer can be provided more for separating finer components from the process air. However, screens and filters or screen and filter coatings may be used interchangeably. The screen can in particular cross the process air channel vertically or obliquely relative thereto.
One design scheme is as follows: the first group has at least two of the following first elements removable from the door fluff screen mount: a multi-pile screen with at least two screen layers, a single-pile screen with one screen layer, a dust filter and/or an adapter without a filter function. In this way, for a functional design of the laundry drying appliance, it is possible to find in a simple manner: whether the multiple lint screen (or generally finer screen separating or filtering), the single lint screen (or generally coarser screen separating or filtering), the fine dust filter or adapter without filtering function should be used for the laundry drying appliance. These first elements can be inserted into the door fluff screen holder and adapted to the corresponding port. The screen and the dust particles (Pollen) are flowed through by the process air and are advantageously sealed against the walls of the process air channel in order to prevent parasitic bypass flows. The multiple fluff screens allow for less costly filtration (or even no filtration) and/or less costly cleaning (or even no cleaning) to continue downstream in the process air channel without significant degradation of filtration efficiency and/or user friendliness.
The single fluff screen also allows (even on a smaller scale than the multiple fluff screens) to continue using less costly filtering (or even no filtering) and/or less costly cleaning (or even no cleaning) downstream in the process air channel without significantly deteriorating the filtering efficiency and/or user friendliness. A single fluff screen is easier to handle and clean than a multiple fluff screen. In this way, a higher process air volume flow is also achieved.
The adapter without a filter function can be produced particularly inexpensively and achieves a particularly high process air volume flow.
There is also a design scheme that: the second group has at least two of the following second elements: a dual water discharge module having: a first water discharge opening for discharging water to the first heat exchanger (especially from above) and a second water discharge opening for discharging water in a region of the process air channel between the first heat exchanger and the front-side cover (especially from above); a single water discharge module having only the first water discharge opening; a cover device without a water discharge function. This allows a variable design of the cleaning function by means of simple means.
The water discharge opening may be a receiving opening for a water dispensing means, such as a nozzle head, or may itself be configured as a water dispensing means.
The dual water drain module enables cleaning of the first heat exchanger and a fluff screen located in the process air channel in the region between the first heat exchanger and the front side cover. In this case there may also be a valve which alternately connects the water supply channel and one of the two water discharge openings.
The single water discharge module and the cap device having no water discharge function may be manufactured without an unused water discharge opening. However, they can also be produced from double water drain modules, wherein the water drain openings, which can also be configured as mold cavities, can be closed off appropriately.
The other design scheme is as follows: the third group has at least two of the following third elements: a first lint trap, the first lint trap having: at least one upper fluff inlet opening between the cover and the first heat exchanger, at least one upper injection opening and at least one lower output opening below the first heat exchanger; a second lint trap with at least one upper side injection opening located below the first heat exchanger and at least one lower side output opening and/or an intermediate bottom with at least one output opening arranged below the first heat exchanger. A lint trap can be understood in particular as a lint collecting container for lint.
The first lint trap realizes: -the entry of fluff, hairs or the like falling from the first heat exchanger through the at least one upper side injection opening located below the first heat exchanger, and-the entry of fluff, hairs or the like cleaned from the area of the process air channel between the first heat exchanger and the front side cover through the at least one upper side fluff entry opening ("wash-in slit") between the cover and the first heat exchanger.
The second lint trap does not: entry of lint, hair, etc. cleaned from the area of the process air passage between the first heat exchanger and the front side cover.
Both lint pickers can be removed by the user.
The intermediate bottom has no lint collecting function and can be constructed particularly simply. The intermediate bottom can be fixedly fastened in the laundry drying appliance. The intermediate bottom can have at least one through-opening below the first heat exchanger, through which the condensation water produced in the drying operation can pass. The intermediate base may be configured as a base assembly insert. The intermediate bottom may have an air guiding function.
Still another design is: the fourth group has at least two of the following fourth elements: a cover with a simple fluff screen arranged in the process air channel, in particular in front view between the cover and the first heat exchanger, a cover with a (functionally) reinforced fluff screen and/or a cover without a fluff screen arranged in the process air channel between the cover and the first heat exchanger.
Fluff, hairs and the like can also be filtered out by the simple fluff screen and the reinforced fluff screen in the flow technology section of the process air channel between the door fluff screen holder and the first heat exchanger.
The simple fluff sieve may in particular be a fine mesh fluff sieve.
The functionally enhanced fluff screen has, inter alia, an enhanced filtering effect compared to the simple fluff screen. The reinforcing fluff screen can, for example, have at least one additional filter stage, which can, for example, comprise a screen coating, a sponge and/or a nonwoven.
The lint screen may include a sealing device or system to avoid parasitic air bypass ("bypass") of lint, hair, etc. passing through the lint screen.
The cover without the fluff screen can be produced particularly simply.
The other design scheme is as follows: the micro dust filter or the adapter without filtering function is inserted into the door fluff sieve base, the double water discharging module is inserted into the diffuser base, the first fluff catcher is inserted into the lower cladding base and the cover with the simple fluff sieve is inserted into the cover base. In this way, a laundry drying appliance can be produced in which the process air with fluff or the like adhering to it first flows into the section of the process air channel in which the fine-dust filter or the adapter without filter function is located. If, for example, the adapter piece without the filter function is inserted, the process air flows unfiltered through this section of the process air channel into a space which is located between the adapter piece and the first heat exchanger. The process air is there filtered by the simple fluff sieve of the cover seat, so that a portion of fluff or the like is deposited thereon. A cover as such or a corresponding cover serves to close the process air channel on the front side and to direct the air in the direction of the first heat exchanger, if necessary. The process air enters the first heat exchanger after the fluff screen of the cover seat and condenses there. The fluff still present thereafter deposits on the first heat exchanger or drips off together with the condensate. The condensed water which has dripped off and still has a fluff adhering to it partially enters the first fluff trap through the at least one upper fluff inlet opening and is then discharged again through the at least one lower outlet opening, for example into a collection basin. The at least one lower outlet opening is covered by a pile screen, so that there is also a hold of piles, hairs etc. The condensate draining from the first lint trap is substantially lint-free.
The process air flowing through the first heat exchanger is drier than before and also has only a small amount of fluff. It then reaches the second heat exchanger, for example, and is heated again there. Then, the hot dry process air is again introduced into the laundry drum.
To clean the cover fluff screen and the first heat exchanger, the dual water discharge module is inserted into the diffuser seat. Through the first water discharge opening, water can be given to the first heat exchanger from above, which drips down on the first heat exchanger with lint and the like adhering thereto and then enters the lint trap like condensed water.
For this purpose, the first water discharge opening is arranged, in particular in flow technology, behind the cover sieve.
Through which water can be given from above to the cover fluff screen, in such a way that fluff etc. adhering there is entrained with the water flow. Thereby cleaning the fluff screen. The second water discharge opening is located in particular above the cover fluff screen. The cover fluff screen can be mounted, in particular, obliquely with respect to the vertical, for achieving a particularly effective flow of water through the fluff screen from top to bottom. The downflowing water enters the fluff trap through the at least one upper fluff inlet opening between the cover and the first heat exchanger and is discharged from there through the at least one lower outlet opening. The fluff is trapped in the fluff trap. The second water discharge opening is arranged in a flowable manner in front of or behind the cover fluff screen.
Whereby water under pressure can be selectively discharged through the water discharge opening for cleaning the first heat exchanger or the cover fluff screen.
The cover can be connected with the lint picker in order to be able to remove not only the attached lint screen from the laundry drying appliance, but also the lint picker, for example for cleaning or, if necessary, emptying thereof, by removing the cover. That is, the lint trap can be removably inserted into its seat. Here, there may be a mechanical connection of the cover and the lint trap that can be detached and assembled again by a user outside the laundry drying appliance.
There is also a design scheme that: the single pile screen is inserted into the door pile screen seat, the single water drain module is inserted into the diffuser seat, the second pile catcher is inserted into the lower deck seat, and the cover without a pile screen is inserted into the cover seat. In contrast to the previously described embodiment, the adapter or the particle filter is therefore replaced by the single-fluff screen, which is also suitable for the door-fluff screen holder. The cover fluff screen may thereby be eliminated. Since there is thus also no cover fluff screen to clean, the double water drain module can be replaced by a single water drain module adapted to the same seat. The first heat exchanger may be cleaned by the single water drain module similar to the double water drain module. The changeover valve may be eliminated. Since the lint screen without a cover needs to be cleaned, the at least one upper lint inlet opening between the cover and the first heat exchanger can also be dispensed with, which also prevents a parasitic air bypass flow there particularly reliably.
In addition, one design solution is: the multiple pile sieves are inserted into the door pile sieve base, the cover device without water discharge function is inserted into the diffuser base, the middle bottom is inserted into the lower deck base, and the cover with the (function) reinforcing pile sieve is inserted into the cover base. A particularly effective fluff filtration is already achieved by the multiple fluff screen shortly behind the laundry drum. Fluff and the like that may still have flushed through the multiple fluff screen are again held particularly effectively in the reinforced fluff screen. Cleaning the first heat exchanger with water can thus be dispensed with. Thus, a cover device without a water discharge function can be inserted sealingly in the diffuser seat in the wall of the process air channel, in which case a water discharge module is inserted. Since no cleaning with water is performed anymore, it is no longer necessary to provide a lint trap. Instead, it is sufficient to use a simple intermediate bottom. The intermediate bottom no longer needs to be removable and connected to the lid.
In order to ensure a correct pairing of suitable third and fourth elements, in particular of a suitable cover and lint trap, these elements can be connected to one another by means of a mistake-proof connection or be constructed as mistake-proof elements.
The object is also achieved by a laundry drying appliance produced by the above-described method. The laundry drying appliance may be constructed similar to the method and yield the same advantages.
For example, in one embodiment, the laundry drying appliance has: a process air channel; a door fluff screen seat located in the process air channel and laterally arranged on a feed opening for a laundry drum; a diffuser seat in the wall of the process air channel, which diffuser seat is arranged in particular above and in front of the first heat exchanger; a lower cladding seat for arranging a fourth element below the first heat exchanger and a front cover seat arranged below the door fluff screen seat and in front of the first heat exchanger.
The above-described attributes, features and advantages of the present invention, as well as the manner and method of attaining them, will become more apparent and the invention will be better understood by reference to the following description of illustrative embodiments, which is to be read in conjunction with the accompanying drawings.

fig. 2 shows a section of a laundry dryer according to a second exemplary embodiment in a side view, in sections as a sectional view; and
fig. 3 shows a section of a laundry dryer according to a third exemplary embodiment in a side view in section as a sectional view.
Detailed Description
Fig. 1 shows a section of a laundry drying appliance in the form of a laundry dryer 1 according to a first embodiment in a side view as a sectional view. The laundry dryer 1 is manufactured such that a first element in the form of an adapter (upper figure) is inserted into a door fluff screen holder 2 in a process air channel 3. Process air P flowing out of the laundry drum (upper drawing) is substantially directed through the adapter. The adapter can be designed in such a way that it prevents laundry from flooding into the process air channel 3, for example in such a way that: the adapter has a mesh grid on the upper side.
The process air P flows behind the adapter into the region 3a of the process air channel 3, which is closed off on the front side by a cover 4 and which abuts on the rear side against a first heat exchanger 5. The cover 4 has a cover element 6 for closing the process air channel 3 on the front side and a fluff screen 7 connected on the inside. The cover 6 serves as a cover seat 8 of the process air channel 3 in the region of a wall that can be removed on the user side and is inserted therein. The fluff screen 7 is located vertically in the zone 3a and is constructed as a fine-mesh single-layer ("simple") fluff screen. The fluff screen is inserted in the process air channel 3 in a closed manner in a circulating manner such that no parasitic air bypass occurs around the fluff screen 7.
Furthermore, a double water discharge module 9 is inserted into the diffuser seat 10 above the first heat exchanger 5 and above the fluff screen 7. The diffuser base 10 is located partly above the first heat exchanger 5 and partly in front of the first heat exchanger 5 in a plan view.
The double water drain module 9 has a first water drain opening 11, through which first water drain opening 11 pressurized water can be supplied onto the first heat exchanger 5 from above. The double water discharge module 9 also has a second water discharge opening 12, through which second water discharge opening 12 pressurized water can be imparted onto the fluff screen 7 from above. The water discharge openings 11 and 12 can be selectively selected for water discharge, for example by means of a valve (upper drawing). The first water discharge opening 11 is arranged flow-technically after the fluff screen 7, while the second water discharge opening 12 is arranged flow-technically before the fluff screen 7.
A lint trap 13, inserted in an appurtenant lower cladding seat 14, is located under the area 3a and thus the lint screen 7 and under the first heat exchanger 5. The lint picker 13 has at least one upper lint entry opening in the form of an impact slot 15, which is located immediately in front of the lower edge of the lint screen 7. The lint trap 13 also has at least one upper side injection opening 16 and at least one lower side outlet opening 17, which are located below the first heat exchanger 5. The at least one lower outlet opening 17 is covered by a screen coating 18.
A second heat exchanger 19 is arranged in the process air channel 3 at a distance behind the first heat exchanger 5. The first heat exchanger 5 and the second heat exchanger 19 may be components of a heat pump, for example the first heat exchanger 5 may be an evaporator and the second heat exchanger 19 may be a condenser.
During dry operation of the laundry dryer 1, process air P, which is initially loaded with fluff, flows into the region 3a of the process air channel 3 and through the fluff screen 7, as described above. The process air P which has passed through the fluff screen 7 has a significantly smaller proportion of fluff, hairs or the like which instead settle on the fluff screen 7. The process air P continues to flow through the first heat exchanger 5, where it condenses on the first heat exchanger 5 together with the vast majority of fluff etc. that has remained so far. Condensed water (shown by black arrows) drips or flows through the at least one upper side injection opening 16 into the fluff trap 13 and from there through the at least one lower side output opening 17 into a collection tray (upper drawing). The fluff carried by the condensed water is trapped by the screening layer 18. Another part of the fluff remains attached to said first heat exchanger 5. The process air P, which is now largely fluff-free, flows after the first heat exchanger 5 to the second heat exchanger 19 and is heated again there.
In cleaning operation, water under pressure is alternately sprayed and/or sprinkled from said water discharge openings 11 and 12 and onto said first heat exchanger 5 or onto said fluff screen 7, thereby cleaning fluff or the like adhering thereto. The water flowing away from the lint filter 7, carrying the attached lint (see attached black arrows), enters the lint trap 13 through the flushing gap 15. The water flowing away from the first heat exchanger 5, carrying fluff attached thereto, enters the fluff trap 13 through the at least one upper side injection opening 16 (see attached black arrows).
The cover 4 is connected with the lint trap 13 by means of a mistake-proof connection (Poka-Yoke-verbundling) in order to be able to remove the lint trap 13 also from the laundry dryer 1 by removing the cover 4, for example for cleaning and optionally emptying thereof. That is, the lint trap 13 is removably insertable into the laundry dryer 1.
Fig. 2 shows a section of a laundry dryer 21 according to a second exemplary embodiment in a side view in section as a sectional view.
In contrast to the laundry dryer 21, a door fluff screen in the form of a single fluff screen 22 is inserted into the door fluff screen holder 2 instead of the adapter. For this purpose, the cover 23 no longer has a fluff screen, but is also inserted into the cover seat 8. Furthermore, a single water discharge module 24 having the water discharge opening 11 for cleaning the first heat exchanger 5 instead of the water discharge opening 12 is inserted in the diffuser seat 10 instead of the double water discharge module 9. This also makes it possible to dispense with the valve.
The lint trap 25 is constructed similarly to the lint trap 13, but now no longer has a wash-in gap. A lint trap 25 is inserted into the lower deck seat 14. The cover 23 is connected with the lint trap 25 by means of a mistake-proof connection, so that the lint trap 25 can also be removed from the laundry dryer 21 by removing the cover 23.
Fig. 3 shows a section of a laundry dryer 31 according to a third exemplary embodiment in a side view in section as a sectional view.
Compared to the laundry dryer 1, a multiple fluff screen 32 with more than one screen coating is inserted into the door fluff screen holder 2. The fluff screen 33 of the cover 34 is reinforced as follows: in addition to the screen coating 7, a further screen coating, sponge coating or nonwoven coating 35 is present, for example. But no water-based cleaning system is present anymore, so that in said diffuser seat 10 a cover device 36 is inserted which does not have a water discharge function. The lint trap can thus be eliminated. Instead, an intermediate bottom 37 is inserted into the lower cladding seat 14. The intermediate bottom 37 no longer needs to be removable and does not need to be connected to the lid 34. During the drying operation, condensate which flows off or drips off from the first heat exchanger 5 can pass through the through-openings 38 in the intermediate bottom 37 and further to, for example, an outlet tank (upper drawing).
The invention is of course not limited to the embodiments shown.
In general, "a" or "an" should be understood to mean one or more, especially in the sense of "at least one" or "one or more", etc., as long as they are not explicitly excluded by the word such as "exactly one".
Likewise, the numerical descriptions may be of the exact numerical values given, as long as such are not expressly excluded, or may include common tolerance ranges.
