Definitions

  • the invention relates to a laundry treatment cabinet, such as e.g. a clothes drying cabinet.
  • a laundry treatment cabinet such as e.g. a clothes drying cabinet.
  • This is a device with a resting in operation, i. non-rotating, useful space in which the laundry is introduced for treatment.
  • the device has means for laundry treatment provided, such. a drying plant or a vaporization plant.
  • Cabinets of this kind serve e.g. for drying laundry, but also for refreshing or for the odor treatment of laundry.
  • EP 2 330 247 is described a cabinet dryer for laundry, in which the process air sucked through a lower vent opening from the work space and drying and heating by the evaporator and the condenser a heat pump assembly is guided. Then the air is conveyed by air conveyors through a connecting channel at the back of the unit to upper vents, from where the air is reintroduced into the utility room.
  • the heat pump assembly is housed in a machine room below the utility room.
  • the object of the present invention is to provide a device of the type mentioned, which has a compact design.
  • the device has a housing with a front and a back. In the housing, an interior space and an engine room arranged below the interior are provided. In the engine room, a heat pump assembly with compressor, condenser, expansion valve and evaporator is arranged. With the compressor, a heat pump medium is pumped through the condenser, the expansion valve and the evaporator, which heats the condenser and cools the evaporator. At least one lower ventilation opening is provided at the lower end of the utility space and at least one upper ventilation opening is provided at the upper end. A connecting channel extends between the engine room and the upper ventilation opening.
  • air conveying means are provided to convey air from the work space through the lower vent opening, the heat pump assembly, the connection duct and the upper vent opening back into the work space, or vice versa.
  • the connecting channel is arranged according to claim laterally outside one of the side walls of the work space. In contrast to the solution according to the prior art, where the connecting channel behind is the utility room, is thus at the same depth more space for receiving the laundry available.
  • This arrangement is based on the recognition that in practice the overall depth of the device is more limited than its width.
  • the evaporator and the condenser in a direction parallel to the front of the housing, are arranged side by side, i. air delivered in this direction first hits the evaporator and then the condenser. In this way, the air without further substantial horizontal deflection to the connecting channel (or possibly in the opposite direction) are performed.
  • the lower ventilation opening is advantageously located at the bottom of the utility room, where a large area is available.
  • the bottom vent may be followed by a downwardly tapered (i.e., narrower towards the bottom) first duct section which terminates at an inlet side of the evaporator. So the air can be collected and led to the entrance of the evaporator.
  • the compressor is disposed in a portion of the engine room behind the evaporator and the condenser, thereby reducing the noise emission to the front.
  • the heat pump arrangement in addition to the condenser and the evaporator, has an additional heat exchanger through which the heat pump medium, but not the process air, flows. This is preferably arranged in the path of the medium between the condenser and the expansion valve. Further, a fan for cooling the additional heat exchanger is provided. In this way, excess heat can be removed from the device.
  • the additional heat exchanger is advantageously arranged in the section of the engine room behind the evaporator and the condenser, resulting in a compact design with low noise emissions leads to the front.
  • the expansion valve may be disposed in the portion of the engine room behind the evaporator and the condenser, whereby it is also cooled.
  • a plurality of upper ventilation openings are arranged on the ceiling of the work space, which lead to a ceiling duct above the working space.
  • the ceiling channel is connected to the connection channel and tapers away from the connection channel, i. the height of the ceiling channel decreases starting from the connecting channel. In this way, the air can be distributed evenly to the upper vents.
  • a plurality of air baffles can further be provided which protrude transversely to the ceiling of the working space in the ceiling channel.
  • connection channel is arranged laterally of a side wall of the work space, i. in horizontal direction parallel to the front side, the side wall of the work space and the connecting channel overlap.
  • FIG. 1-5 An advantageous embodiment of the laundry treatment cabinet is in Fig. 1-5 shown, and the main functional components are in Fig. 6 shown.
  • the laundry treatment cabinet has a substantially cuboid housing 1 with a front 2 and a back 3 ( FIGS. 3 and 5 ), two perpendicular to the front and rear side walls 4, 5 ( Fig. 1 and 5 ), a bottom 6 and a top 7 ( Fig. 1 ).
  • a door 10 On the front side 2 of the device, a door 10 is provided, which can be opened about a vertical pivot axis 11 ( Fig. 1 and 3 ).
  • the door 10 closes a work space 12, which also has a substantially cuboid shape.
  • a work space 12 Below the working space 12, an engine room 14 adjoins.
  • a shaft space 15 is provided and above the work space 12, a ceiling space 16 (FIG. Fig. 4 ).
  • the work space 12 is to the rear of a rear wall 13 a ( Fig. 3 ), laterally of side walls 13b, 13c ( Fig. 2 . 4 ) is bounded above by a ceiling 13d, downwardly by a floor 13e and forwardly by a door opening 13f which can be closed by the door 10 ( Fig. 4 ). It serves to receive the laundry.
  • suitable means are provided for receiving laundry in the useful space, such as a rod 17 for receiving hangers, a pivoting rake 18 for suspending individual pieces of clothing or baskets 19 (FIGS. Fig. 2 . 3, 4 ).
  • the usable space 12 is accessible via the door 10.
  • a heat pump assembly including a compressor 20, a condenser 21, an auxiliary heat exchanger 22, an expansion valve 23 and an evaporator 24 is provided.
  • a medium is passed in a known manner through the condenser 21, the additional heat exchanger 22, the expansion valve 23, the evaporator 24 and back to the compressor, whereby the condenser 21 is heated and the evaporator 21 is cooled ( Fig. 5 . 6 ).
  • the additional heat exchanger 22 serves in the in EP 2 034 084 described manner to deprive the system heat.
  • a fan 26 is provided, the cooling air from the environment through the additional heat exchanger 22 and via the expansion valve 23 and the compressor 20 leads.
  • a steam generator 28 is provided in the engine room 14, with which steam for introduction into the process air can be generated. As in EP 2 330 247 described, the steam can be used to refresh the laundry and / or wrinkle.
  • At least one upper or lower ventilation opening 30, 31 are provided at the upper and at the lower end of the work space 12.
  • a plurality of small upper vents 30 and a large lower vents 31 are shown.
  • the area covered in the ceiling and / or in the bottom of the work space 12 by the ventilation opening or ventilation openings 30 preferably comprises at least 50%, in particular at least 75%, of the total area the ceiling or the floor of the utility room. If several ventilation openings are provided, the "covered area" is to be understood as the area covered by the convex envelope of the ventilation openings.
  • an air circulation in the opposite direction is conceivable.
  • the lower vent opening 31 is covered by a grid plate 33, ie a rigid plate in which a plurality of openings is provided.
  • the grid plate 33 is inserted at the bottom of the work space 12 and can be removed by the user from the work space, for example, to gain access to the underlying air filter, which are described below.
  • a first channel section 34 arranged in the machine room 14 and tapering towards the bottom, which adjoins an inlet side of the evaporator 24, closes.
  • a first and a second air filter 35 and 36 are spaced above each other. These form a two-stage filter to keep contaminants away from the heat exchangers of the evaporator 24 and the condenser 21.
  • the first, upper air filter 35 is preferably coarser than the second, lower air filter 36.
  • the two air filters 35, 36 can be removed from the first channel section 34, one after the other, from above.
  • a first shoulder 37 and a second shoulder 38 are provided in the first channel portion 34, which is spaced apart and on each of which the edge of one of the air filters 35 and 36 rests.
  • the evaporator 24 and the condenser 21 are arranged in a second passage section 38 adjoining the first passage section 34, which passes the air through the heat exchangers of the evaporator 24 and the condenser 21.
  • a third channel section 39 adjoins, which tapers and opens in the suction region of a radial fan 40, which forms the air conveying means for conveying the process air.
  • the radial fan 40 and a connecting to the radial fan 40 connecting channel 41 are arranged in the lateral shaft space 15 of the laundry treatment cabinet.
  • the air is passed from the radial fan 40 in the connecting channel 41, in which it rises to the ceiling space 16 of the device.
  • a light source 42 and at least one catalyst surface 43 are arranged for the photocatalytic air treatment ( Fig. 4 ). With such an arrangement, such as in EP 2 241 826 described in more detail, unwanted organic compounds in the process air can be degraded.
  • a heater 44 is arranged in the connecting channel 41, with which the purified air can be heated if necessary.
  • the arrangement of the heater 44 after, i. above, the light source 42 improves the photocatalysis, which thus occurs at lower temperatures.
  • the connecting channel 41 merges into a horizontally extending ceiling channel 46, which is arranged above the useful space 12.
  • the upper ventilation openings 30 of the work space 12 are connected to this ceiling channel, so that the air from the ceiling channel 46 can flow from above into the working space.
  • At least one bent deflecting plate 47 may be provided in the interior of the transitional region between the connecting channel 41 and the ceiling channel 46.
  • the ceiling channel 46 tapers in the direction away from the connecting channel 41, which helps that the local pressure at each of the upper openings 30 is approximately equal, so that in the work space 12 as homogeneous a flow of air is established.
  • baffles 48 may be provided to redirect the air to the upper ventilation openings 30.
  • these air baffles 48 project transversely to the ceiling of the work space 12 in the ceiling duct 46.
  • the connecting channel 41 is arranged in the shaft space 15 laterally of the work space 12.
  • an operating area 50 with input and / or output means 51 which serves to control or monitor the laundry treatment cabinet, is arranged on the front side of the appliance ( Fig. 1, 2 ). How out Fig. 4 can be seen, the door 10 does not extend beyond the operating area 50 in the closed state, so that it is not covered and, for example, remains accessible during operation.
  • the input and / or output means 51 are connected to a device control 52 ( Fig. 6 ), which controls the operation of the various components of the device.
  • the machine room 14 of the laundry treatment cabinet is, as already mentioned, designed for a compact, low-noise construction. Various measures contribute to this.
  • the evaporator 24 and the condenser 21 are arranged side by side in the direction parallel to the front side 2, as is apparent from Fig. 5 can be seen, so that the air without further horizontal deflection to the radial fan 40 and the connecting channel 41 can be performed.
  • the first channel section 34 is able to draw off the air over a large area of the bottom of the interior and lead to the evaporator 24 specifically due to its downwardly tapered shape.
  • the compressor 20, the expansion valve 23, the auxiliary heat exchanger 22 and the fan 26 use the space in a portion 54 of the engine room 14 behind the evaporator 24 and condenser 21.
  • the forward noise emissions can thus be reduced.
  • this section 54 is limited to the front at least partially by a wall 55, which guides the cooling air from the fan 26 and at the same time causes a sound insulation.
  • the wall is located in particular in the region between the additional heat exchanger 22 and the evaporator 24 and the condenser 21 and / or in a region between the compressor 20 and the evaporator 24 and the condenser 21.
  • rear ventilation openings 56 (FIG. Fig. 5 ) are provided, and on the front side 2 are located at the bottom front ventilation holes 57 ( Fig. 1, 2 . 3, 5 ). With the fan 40, ambient air can be conveyed between these ventilation openings, preferably from the front ventilation openings 57 to the rear ventilation openings 56.
  • a channel gap 58 is provided ( Fig. 3, 4 ), which connects the front vents 57 with the suction region of the fan 26.
  • an indicated by arrows 59 air flow ( Fig. 3, 5 ) are led from the front through the device to the fan 26.
  • the direction of the airflow can also be from back to front.
  • the steam generator 28 is also located in section 54 behind the evaporator 24 and the condenser 21, where it fits well. In addition, it can be cooled by the air of the fan 26, if so desired.
  • two pivotable container 61 are arranged in the machine room 14, each of which receives a removable tank 62.
  • One of these tanks forms a fresh water tank for the steam generator 28, and the other a waste water tank, which is received in the bottom of the engine room 14 by a trough, not shown, in particular for water, which was excreted from the evaporator 24 from the process air.
