Abstract
Refrigeration device comprising a water filter, which is housed in a central cavity of a coil condenser.
Description
- The present invention relates to a refrigeration device comprising a water filter and a coil condenser.
- Since water dispensers and automatic ice makers have become less and less expensive and more and more common, domestic refrigerators are increasingly being equipped with water filters in order to filter the water for the water dispenser and the automatic ice maker. Such a water filter is known from U.S. Pat. No. 6,355,177 B2.
- Coil condensers are built into more and more refrigeration devices to be able, among other things, to situate the condenser within the machine compartment. In the case of a coil condenser, the condenser has an essentially helical form and occupies a considerable volume in the space where it is located. Such a coil condenser is known from U.S. Pat. No. 5,592,829.
- As a result of the increasing number of additional components built into refrigeration devices, the available space for the individual components is becoming more and more restricted.
- Until now, the water filter was usually located in the cold compartment of the devices, and in the base of the device in some cases. Location in the base gives the disadvantage that the base has to be increased in height, which reduces the interior space. However, building it into the interior space results in the problem that the usable volume in the interior space is reduced.
- One object of the present invention is to arrange the water filter such that better use is made of the available space.
- According to the invention this is achieved by housing the water filter in a central cavity of a coil condenser.
- As until now there are usually no components in the central cavities of refrigeration device coil condensers, these can be used for housing the water filters.
- By this means a refrigeration device can be equipped with a water filter without the need to reduce the interior space or its usable volume. Housing the water filter in the central cavity of the coil condenser prevents an air stream created by a fan from circumventing the condenser by flowing through the central cavity. Blocking the central cavity thereby becomes redundant.
- In a preferred embodiment of the invention the water filter is surrounded by a sleeve. This serves to protect the water filter from the heat radiated from the coil condenser.
- In a further embodiment of the invention it is advantageous for the sleeve to have surfaces that reflect radiant heat. Mirror-like surfaces, such as those of metallic materials, are particularly suitable. This reduces the exchange of heat between the coil condenser and the water filter.
- For this it is appropriate if the water filter includes a filter base and a replaceable filter cartridge installable in said filter base. This enables replacement of the filter cartridge to be performed relatively simply.
- It is advantageous if the filter base is located adjacent to a first axial end of the central cavity and the filter cartridge can be inserted into the cavity from the other axial end. This makes particularly effective use of the available space in the central cavity.
- It is advantageous for the filter base to be located on the axis outside the cavity. This enables the filter base to be mounted relatively simply in the refrigeration device.
- Alternatively a fan motor can be brought into the cavity and the filter base located in the cavity adjacent to the fan motor. If a fan motor is included in the central cavity, the water filter can then be housed in the remaining part of the cavity. The filter base of the water filter can then be mounted adjacent to the fan motor.
- In another embodiment of the invention, a drip pan is arranged at least under the
filter base 2. This has the effect that when the water filter is replaced, any escaping water is caught in the drip pan and does not reach the interior of the refrigeration device. - The idea of the invention also provides for the ability to insert the filter cartridge into the cavity through an opening formed in an exterior wall of the housing of the refrigeration device. This gives the user easy access to the water filter and enables unproblematic replacement of the filter cartridge. It is then not necessary to open the device when replacing the water filter.
- It can also be advantageous to arrange the opening on the front side of the housing. If, for example, the refrigeration device is built into a fitted kitchen or is positioned against a wall, the water filter can be replaced without the need to move the refrigeration device.
- In a further embodiment of the invention the cartridge includes a water-tight capsule containing filter material and a handle section attached to the capsule. The filter cartridge is fixed to the handle section removably or non-removably by screwing, latching, adhesive or welding. Since the handle can serve as an extension it makes it possible to mount the filter in places that are otherwise difficult to access. For the design of the filter handle there are many possibilities, such as in terms of shape and color. This enables the production of many filter handles that are clearly different in their appearance. The filter handle can enclose the filter cartridge entirely, partially or not at all. Simply by replacing the filter handle filter cartridges can be distinguished easily.
- Finally the capsule can be entirely contained in the housing in such a way that it is protected and not visible to the user; the handle section nevertheless enables the filter cartridge to be handled easily.
- Further features and advantages of the invention arise from the following description of exemplary embodiments with reference to the accompanying figures.
- These show:
-
FIG. 1 a sectional diagram of a refrigeration device; -
FIG. 2 a sectional view of a water filter; -
FIG. 3 a longitudinal view through a water filter arranged according to the invention; -
FIG. 4 a perspective view of a partially cut section of a handle section embodied as in the first preferred embodiment, and an end section of a capsule; -
FIG. 5 a longitudinal view through a second arrangement of the water filter; -
FIG. 6 a longitudinal view through a third arrangement of the water filter; and -
FIG. 7 a plan view of a handle section constructed as in a second preferred embodiment. - The refrigeration device shown schematically in
FIG. 1 has a type ofhousing 11 known per se with a thermally insulatedinterior space 25 and below the interior space 25 adevice base 18 in which awater filter 1 is housed. Thedevice base 18 contains further components such as a compressor and a condenser which are known per se and are not shown here. - The
water filter 1 is connected to the process water network of a building by means of asupply line 29 and feeds anautomatic ice maker 26 housed in theinterior space 25, and adispenser 27 for cooled drinking water that is housed in a recess in thedoor 30. - Since valves that are automatically controlled by the water requirement of the
ice maker 26 or thedispenser 27 are known per se they are omitted from the drawing. -
FIG. 2 shows a section through thewater filter 1 and its means of fixing in thedevice base 18 according to a first embodiment. The means of fixing includes a screw-type or bayonet-type base 2 with a radially orientedinlet 14 and an axiallyoriented outlet 15. Afilter cartridge 3 screwed or latched in thebase 2 has a cup-shaped capsule 4 that is equipped adjacent to its open side with an external thread or bayonet ribs that operate in conjunction with thebase 2. Along the longitudinal axis of the cup is atube 31 pierced by a number of holes, of which tube adownstream end 35 at thebase 2 is a tight fit around theoutlet 15. - Inside the capsule 4 a hollow
cylindrical filter body 34 surrounds thetube 31. -
FIG. 3 shows schematically the position of thewater filter 1. The greater part of thewater filter 1 is housed in acentral cavity 7 of acoil condenser 6. Thefilter base 2 is disposed axially external to thecentral cavity 7. With this arrangement it is appropriate to provide anevaporation tray 13 at least under thefilter base 2. By this means, water that may come out of thefilter base 2 when thefilter cartridge 3 is replaced is caught so that it does not drip on to thecoil condenser 6. - Between the
water filter 1 and thecoil condenser 6 there is asleeve 8. Thissleeve 8 extends over the greater part of the length of thewater filter 1. By this means radiant heat of thecoil condenser 6 is reflected. A fan not shown here creates a flow of air through thecoil condenser 6. Between thesleeve 8 and thehandle section 5 there is afirst opening 19 through which air can flow into the region between thewater filter 1 and thesleeve 8. Between thesleeve 8 and thefilter base 2 there is asecond opening 20 through which air can flow out of the region between thewater filter 1 and thesleeve 8. Air within thesleeve 8 is thus constantly exchanged, so that air that may be warmed despite the shielding by thesleeve 8 is immediately removed. In this manner thewater filter 1 is kept cool. Since the water that flows through the water filter is later cooled as drinking water or frozen into ice cubes, it is appropriate that it should not be warmed unnecessarily. Thefilter cartridge 3 has here ahandle section 5 attached to thecapsule 4. -
FIG. 4 shows thehandle section 5 in a preferred embodiment with an end section of thecapsule 4 in a partial perspective view. Thehandle section 5 that is formed as a single piece of plastic has a cup- or dish-shapedsection 21 that encloses the opposite end of thecapsule 4 to thebase 2. By this means a relatively large contact area is achieved that offers various possibilities for joining such as pressing, use of adhesive, welding or latching. From a base surface of the cup- or dish-shaped section there projects arib 22 that a user can conveniently grasp and rotate in order to remove thefilter cartridge 3 without the assistance of a tool. -
FIG. 5 shows a second arrangement of thewater filter 1 according to the invention within thehousing 11 of a refrigerator.Water filter 1,fan motor 10 andcoil condenser 6 are arranged adjacent to anopening 12 in thehousing 11. They are arranged in such a way that thehandle section 5 faces thehousing opening 12. The cup-shapedsection 21 ends flush with thehousing 11. This avoids the user trapping fingers between thehandle section 5 and the edge of theopening 12 when removing thefilter cartridge 3. Therib 22 protrudes here beyond thehousing 11 and so facilitates accessing therib 22. - Unlike the arrangement shown in
FIG. 3 , thefilter base 2 is here within thecentral cavity 7 of thecoil condenser 6. Additionally there is also afan motor 10 for a fan within thecentral cavity 7 of thecoil condenser 6. Here thefan motor 10 and thewater filter 1 are arranged at axially opposite ends of thecentral cavity 7.Fan motor 10 andfilter base 2 are adjacent to each other and consequently thefilter base 2 and thefan motor 10 can be affixed next to each other or on a common carrier (not shown). - The embodiment shown in
FIG. 6 has adrip pan 9. This is disposed below thewater filter 1 betweensleeve 8 andcoil condenser 6. It extends axially from theopening 12 in thehousing 11 as far as beneath thefilter base 2. Additionally anevaporation tray 13 is provided that is here disposed below adrip edge 23 of thedrip pan 9. The provision of thedrip pan 9 prevents water that may come out when thefilter cartridge 3 is changed from reaching the interior of the refrigeration device. Water that comes out when thefilter cartridge 3 is changed is caught in thedrip pan 9 and led to theevaporation tray 13. - Unlike the embodiment shown in
FIG. 5 the cup-shapedsection 21 of thehandle section 5 is here recessed in thehousing 11. In order to avoid the user trapping fingers between thehandle section 5 and the edge of theopening 12 when removing thefilter cartridge 3, the handle section is here provided with a ring-shaped ridge 16 that surrounds therib 22. The upper edges of the ridge 16 andrib 22 are flush with thehousing 11. -
FIG. 7 shows the front face of thehandle section 5 as inFIG. 6 in plan view. Through the provision of two recessed essentially semi-circular finger hollows 17, the fingers of a user are within a ring-shapedridge 24 when changing the filter cartridge. This avoids the possibility that the fingers can become trapped between thehandle section 5 and thehousing 11. Between the finger hollows 17 there is aridge 22 that the user can grasp and rotate.
