Description

The invention relates to a floor module and a floor module device for a heat pump dryer, a heat pump dryer and a method for manufacturing a floor module device for a heat pump dryer. The refrigeration compressors of heat pump dryers are mounted in a base module assembly, which typically houses the refrigeration unit. Rotary piston compressors usually have a welded-on triangular base plate with a hole at each corner. An elastomer component is inserted into this hole, acting as an elastic bearing for the compressor. The compressor can be protected against shock by passing a threaded bolt through the elastomer components. This bolt is firmly connected to the sheet metal base (compressor mounting) and secured by additional steel sleeves tightened with washers and nuts. This securing mechanism prevents the compressor from being pulled out of the base plate if it tips over. Alternatively, compressor mountings designed as triangular sheet metal trays are used, which are fastened to the base module with three or more bolts.During this adaptation, care must be taken to ensure that the elastomer parts are not subjected to tension. DE 20 2014 000 975 U1 describes a corresponding attachment of a compressor to a base module of a heat pump dryer. WO 2014 / 090 962 A1 shows another fastening method with drill holes and support elements. The invention is based on the objective of creating an improved floor module and an improved floor module device for a heat pump dryer, an improved heat pump dryer and an improved method for manufacturing a floor module device for a heat pump dryer. According to the invention, this problem is solved by a base module and a base module device for a heat pump dryer, a heat pump dryer, and a method for manufacturing a base module device for a heat pump dryer with the features of the main claims. Advantageous embodiments and further developments of the invention are described in the dependent claims. The advantages achievable with the invention lie in the fact that a secure attachment of the compressor to the base module can be realized with minimal material expenditure. Such an attachment withstands the usual shock, tip-over, and drop tests, which generate considerable accelerations on the base module assembly. Combined with the high mass of the refrigeration compressor (approximately 7-8 kg) in the household appliance and its high center of gravity, significant forces and moments are exerted, which the compressor mounting described here, as the interface to the compressor, is designed to withstand. The compressor can be screwed directly into the base module, which simplifies installation while still meeting the required strength standards. Advantageously, the described approach does not require an additional sheet metal tray with pressed-in threaded bolts and steel sleeves to accommodate the existing compressor bearings and the compressor itself. This solution is easy to install and inexpensive. A base module for a heat pump dryer has a compressor mounting area with three mounting elements for accommodating the three compressor feet. Each of the three mounting elements has a through-hole for receiving threaded sections of screws to secure the three compressor feet to the mounting elements. Within the compressor mounting area, a central support area is arranged between the three mounting elements, shaped to accommodate an elastic central support element for the compressor. Between the central support element and the three mounting elements for the compressor feet, three further elastic support areas are arranged, each shaped to accommodate an elastic lateral support element for the three compressor feet. A heat pump dryer can be a household appliance with a heat pump for drying laundry. It can also be a washer-dryer, in which laundry can be washed before drying. A base module is a support element for components of the heat pump dryer, such as the compressor. The base module can be made of plastic, for example. The threaded sections of the screws are screwed into the mounting elements to attach the compressor feet. When mounted, the compressor can be supported by the central support element, which is designed to bear the weight of the compressor.The three compressor feet can be positioned on the three support areas adjacent to the mounting elements when the compressor is mounted, in order to prevent the compressor from tipping over during operation. This approach offers a cost advantage because it eliminates the need for the usual sheet metal tray for the compressor and its associated mounting hardware. Furthermore, assembly is very simple. The screws and washers used for transport securing can be very inexpensive because they can be screwed directly into the plastic tray. The transmission of compressor vibrations to the base module is reduced, as the compressor's vibration amplitude is minimal where it rests on the central support element, such as an elastomer ring. The system is insensitive to resonances because the resonance frequencies are significantly lower than the excitation frequency. Additionally, the overall height is very low, as the increased number of elastomer elements allows for a flatter design while still achieving the desired damping performance. According to one embodiment, an elastic central support element can be arranged at the central support area of ​​the base module. Additionally or alternatively, elastic lateral support elements can be accommodated at the lateral support areas of the base module. Due to its elastic nature, the central support element can reduce compressor vibrations transmitted to the base module during operation. The central support element can, for example, be ring-shaped or flat. Due to their elastic nature, the lateral support elements can reduce impact movements of the compressor feet on the mounting elements and the base module during tilting movements of the compressor during operation. For example, the central support element beneath the compressor can be a rubber ring. Due to the elastic properties of rubber, reducing compressor vibrations to the base module can be particularly beneficial. The ring shape allows for a stable contact surface for the compressor with minimal material usage. The lateral support elements can each have a rubber rib or be shaped as rubber ribs. The rubber ribs can provide three additional contact surfaces for weight distribution and lateral support of the compressor. Additionally, each lateral support element can have a buffer ring that, when mounted, fits over the corresponding mounting element. Each compressor foot can have a through-hole through which one of the buffer rings is inserted when the compressor is mounted, to provide lateral support for the compressor foot. In one embodiment, the three rubber ribs of the base module can each have a lower height than the three buffer rings. This height difference allows the compressor feet to rest on the rubber ribs and be used as the main contact surfaces for the three compressor feet. In this embodiment, the area of ​​the compressor feet that fits over the receiving element and the buffer rings has freedom of movement. The compressor mounting area of ​​the base module can be shaped to accommodate a one-piece compressor bearing. This one-piece bearing can comprise the central support element and the three lateral support elements. Such a one-piece compressor bearing reduces assembly effort compared to separate support elements. In one embodiment, the base module can include the three screws. When the screws are tightened, a gap can be arranged between the screw heads and the compressor feet when connected to the receiving elements. This gap, when installed, provides clearance for upward movement of the compressor feet. The gap is necessary to allow for free damping of the compressor. The base module can have a recess on the compressor side to accommodate the compressor base, which comprises the three compressor feet. The three lateral support areas and the central support area can be positioned within this recess. The recess prevents the mounting elements with their inserted screws from protruding above the top of the base module. Furthermore, the recess can increase the stability of the base module. The base module can have three protrusions on the compressor side, each extending from the central support area towards the three mounting elements and each corresponding to one of the three lateral support areas. These protrusions enable a more stable design of the base module. A floor module device for a heat pump dryer has the following features: a floor module; the elastic central support element for the compressor, wherein the central support element is received by the central support area of ​​the floor module; the three lateral support elements, wherein the three lateral support elements are received by the three lateral support areas of the floor module; the compressor, wherein the three compressor feet of the compressor are received by the receiving elements of the floor module and the bottom of the compressor is supported by the central support element; and the three screws, wherein the three threaded sections of the screws are inserted from one compressor side of the floor module into the through-holes of the receiving elements. Such a floor module device can be used as a replacement for known floor module devices in a heat pump dryer. A corresponding heat pump dryer comprises a heat pump and a floor module, the compressor of which is part of the heat pump. Due to the stable mounting of the compressor, such a heat pump dryer can be very insensitive to vibrations. A method for manufacturing a base module device for a heat pump dryer comprises the following steps: providing said base module and a compressor with three compressor feet; arranging a central support element for the compressor in the central support area of ​​the base module; arranging three lateral support elements for the compressor feet in the three lateral support areas of the compressor receiving area; arranging the compressor on the compressor side of the base module, wherein the three compressor feet of the compressor are received by the three receiving elements of the base module with the three lateral support elements and one end of the compressor is supported by the central support element; and inserting the threaded sections of three screws from the compressor side of the base module into the through-holes of the receiving elements to fasten the compressor to the base module. Exemplary embodiments of the invention are shown purely schematically in the drawings and are described in more detail below.

Fig. 1 shows a schematic representation of a heat pump dryer 100 according to an exemplary embodiment. The heat pump dryer 100 has a drum 102 for holding laundry to be dried. An interior of the heat pump dryer 100 is enclosed by a housing 104, which also has a filling opening for filling the drum 102 with laundry. A base module 106 is arranged in a lower section of the housing 104. The base module 106 is fixedly connected to the housing 104. The base module 106 can be considered a base element of the heat pump dryer 100 and, according to one embodiment, extends within the housing 104 over at least approximately the entire base surface of the heat pump dryer 100. The base module 106 is shaped to accommodate a compressor 108. Compressor 108 is part of the heat pump of the heat pump dryer 100. In addition to compressor 108, the heat pump includes an evaporator 110, a condenser 112, and an expansion valve 114. The base module 106 can be configured to accommodate additional components 110, 112, and 114 of the heat pump alongside compressor 108. During operation of the heat pump dryer, process air from the drum 102 is directed to the evaporator 110 and dehumidified there. From the evaporator 110, the process air is directed to the condenser 112 and heated. From the condenser 112, the process air is returned to the drum 102 to absorb moisture from the laundry. A refrigerant is circulated from the evaporator 110 to the compressor 108 in a refrigerant circuit. In the compressor 108, the gaseous refrigerant is compressed and fed in compressed form to the condenser 112, in which the gaseous refrigerant condenses.The liquefied refrigerant is routed from the condenser 112 via the throttle back to the evaporator 110 and evaporates in the evaporator 110. Since compressors 108 generally weigh approximately 7-8 kg, it is important to securely fix the compressor 108 to the base module so that it remains firmly in place during operation of the heat pump dryer 100, for example, due to vibrations. Sufficient securing of the compressor 108 is also necessary during transport. Fig. 2 shows an exploded view of a base module device 200 with a base module 106 for a heat pump dryer according to an exemplary embodiment. The base module 106 can be the same as the one described with reference to Fig. 1. Instead of a sheet metal mounting for the compressor, the base module 106 can also include a plastic compressor mounting. Accordingly, the base module 106 can be made of plastic, for example, as an injection-molded part. The base module device 200 comprises a base module 106 with a compressor side 205 facing a compressor 108 and a rear side 210 opposite the compressor side 205. The compressor side 205 of the base module 106 includes a compressor receiving area 215 for receiving the compressor 108. In the center of the compressor receiving area 215, an elastic central support element 220 for a compressor 108 is arranged, the central support element 220 being received by a central support area 225 of the base module 106. To the sides of the central support element 220, three lateral support elements 230 are arranged, the three lateral support elements 230 being received by three lateral support areas 235 of the base module 106.Three compressor feet 240 of the compressor 108 are received by three receiving elements 245 of the base module 106 via three through-holes of the compressor feet 240 of the compressor 108, and one base 250 of the compressor 108 is supported by the central support element 220. The threaded sections of three screws 255 are inserted from the compressor side 205 of the base module 106 into three internal threads of the through-holes 260 of the three receiving elements 245. According to one embodiment, the base module 106 has a recess 265, which is triangular in shape. The base module assembly 200 is essentially triangular in shape, with each of the three corners of the triangle having a receiving element 245 extending from the compressor side 205 towards the compressor 108. The central support area 225 for the compressor 108 is located in the center of the base module assembly 200. The central support area 225 is round and has a recess in its center that terminates at the bottom of the recess 265. Extending from the central support area 225 in this embodiment are three essentially straight protrusions 270, which bulge outwards towards the compressor 108 and terminate at the three receiving elements 245.The three receiving elements 245 have lateral support areas 235, which in turn have three lateral support elements 230. The lateral support elements 230 are essentially ring-shaped and have a through-opening in the middle, through which the support elements 230 are placed over the receiving elements 245. In this embodiment, each of the lateral support elements 230 has a support rib 275 on the side closest to the central support area 225. The three support ribs 275 are each arranged on the three projections 270 and extend from the support surface towards the compressor 108. The three compressor feet 240 of the compressor 108 are arranged on the base 250 of the compressor 108. These feet extend radially outwards from a base body of the compressor 108 and, according to this embodiment, are formed by a metal sheet. According to one embodiment, the compressor feet 240 are part of the compressor 108. According to another embodiment, the compressor feet 240 are rigidly connected to the base body of the compressor 108, for example, by a material-bonded or force-fit connection. According to another embodiment, the compressor feet 240 are formed by a section of a base plate of the compressor 108. Such a base plate can be considered an integral part of the housing of the compressor 108 and may, for example, be welded to the base body of the compressor 108. The base 250 of the compressor 108 is triangular in shape, corresponding to the design of the base module device 200. The compressor feet 240 each have a through-opening shaped to accommodate the mounting elements 245 and the lateral support elements 230. Thus, the compressor 108 can be connected directly to the base module 106, for example, without an additional sheet metal part extending over a base 250 of the compressor 108. The top of the compressor 108 has a connection line 280 for the refrigerant. A washer 285 is arranged between the screws 255 and the compressor feet 240 of the compressor 108. According to one embodiment, the technical means used for the described approach include a recess 265 integrated into the dryer base module, which is also referred to below as a plastic base tray 265 or plastic receiving tray 265; a direct plastic screw connection for transport securing; an elastomer ring 220, which is also referred to below as a central support element 220, a rubber ring 220, or a compressor bearing 220; a compressor bearing 220; and three elastomer support buffers 230, which are also referred to below as lateral support elements 230. According to an alternative embodiment, the compressor bearing 220 and the three support buffers 230 are formed from a single-piece elastomer molded part. According to one embodiment, a plastic mounting tray 265 for the compressor 108 is integrated into the existing base module 106. The compressor 108 is positioned centrally on an elastomer ring 220 inserted into the plastic part, which is designed to support the majority of the compressor 108's weight. To ensure the compressor 108 is vertically aligned, three additional lateral elastomer parts 230 (support buffers 230) are inserted into corresponding molded receptacles 235, which are hereinafter also referred to as lateral receiving areas 235, in the plastic base tray 265. The base plate 250 of the compressor 108, which is hereinafter also referred to as the base 250 of the compressor 108, rests on the support ribs 275 molded onto the elastomer part 230.In the event of device shock or vibrations during transport, the compressor 108 is secured in its position by three inexpensive, plastic-compatible screws 255 and the cylindrical parts of the support buffers 230. The alternative compressor mounting has a low profile. A sheet metal tray can thus be replaced by a plastic component. The plastic component is integrated directly into the existing structure of the base module 106, eliminating the need for separate assembly. This solution is insensitive to creep because the weight force is absorbed by the central, solid rubber ring 220 over a larger cross-section. This solution transmits minimal vibrations to the surrounding base module 106, resulting in improved acoustic performance. Fig. 3 shows a perspective top view of a floor module device 200 in the assembled state according to an exemplary embodiment. The floor module device 200 can be the same as the one described with reference to Fig. 2. The compressor 108 is arranged in the triangular recess 265 of the floor module 106, with the through-openings of the compressor feet 240 of the compressor 108 being received by the receiving elements. The screws are screwed into the receiving elements from the compressor side, with the screw heads 300 of the screws resting on washers 285 arranged between the compressor feet 240 and the screw heads 300. In this position, the compressor 108 is firmly connected to the floor module 106.

In one embodiment, the base module 106 has a triangular recess 265 in the form of a receiving tray 265 integrated into the plastic base module 106 of the dryer for the compressor 108, with a receiving element 245 with a lateral support element 230 placed over it arranged in each of the three corners of the recess 265. The center of the triangular recess 265 has a round central support element 220, which has a hole in its center. In one embodiment, three protrusions 270 of the base module 106 extend from the central support element 220 towards the receiving elements 245.Three support ribs 275, as part of the lateral support elements 230, rest on the three projections 270 of the base module 106. The three support ribs 275 taper essentially to a point from their bearing surface towards the free end. A section 400 of a lateral support element 230 is shown enlarged in Fig. 5. Fig. 5 shows a perspective view of a lateral support element 230 according to an exemplary embodiment. The lateral support element 230 can be the same as the one described in Fig. 4.

The three compressor feet 240 of the compressor 108 project laterally beyond a base body of the compressor 108 and are received by the three corners of the triangular area of ​​the floor module 106. Three round screw heads 300, shown from above, secure the compressor feet 240 of the compressor 108 to the floor module 106. Fig. 7 shows a cross-section through a floor module device 200 in the assembled state according to an exemplary embodiment. The floor module device 200 can be the same as the one described with reference to Fig. 6. The compressor 108, mounted in the receiving tray 265, is fixed to the floor module 106 in a perpendicular direction to the floor module 106. The main weight of the compressor 108 rests on a round elastomer ring 220, which in this embodiment is supported by a central support area 225. The central support area 225 is formed as a projection of the floor module 106. The receiving element 245 is formed by a cylindrical wall section of the floor module 106, which extends from the bottom of the plastic tray 265 towards the compressor side of the floor module 106. The receiving element 245 can be viewed as a protrusion of the bottom of the recess 265 towards the compressor side.The lateral support elastomer buffer 230 rests on the bottom of the recess 265. A gap 700 is provided between a washer located under the screw head 300 and the buffer ring of the lateral support element 230, allowing slight movement of the compressor base 240 relative to the base module 106. A gap 700 is provided between the screw connection, the cylindrical part of the support buffer 230, and the compressor base plate to prevent contact during normal operation and to ensure that the compressor 108 is not impeded during its oscillations, but is only supported in the event of a shock. One side of the washer facing the threaded section of the screw rests on one end of the receiving element 245 facing the compressor side. The compressor base 240 rests on the support rib 270. Figure 7 shows that the compressor base 240 of the compressor 108 is attached to the base module 106 solely by means of the screw, with the main weight of the compressor 108 being supported by the rubber ring 220. This design eliminates the need for an additional compressor mounting, such as a mounting tray, or spacers. Fig. 8 shows a schematic representation of the positioning of the screws 255 on the compressor 108 according to an exemplary embodiment. The screws 255 are received by the through-holes of the compressor feet 240 of the compressor 108. A washer is arranged between the compressor feet 240 and the screw heads of the screws 255.
