    Description

    Field of Invention



    [0001] The invention relates to a home appliance, for example a household refrigerator, having a valve, especially an electromagnetic valve.

    Prior Art



    [0002] One of the example to such valves is disclosed in US2003159453 A. According to the publication, it is a bi-stable electromagnetic valve with a valve chamber arranged between two pole pieces and a valve body displaceable therein between two end positions, which is designed as a magnet armature for at least one permanent magnet and for at least one control coil, which is less susceptible to faults in comparison to known valves for refrigerant circuits.

    [0003] FR 2 600 150 A1 describes a refrigerator comprising a cooling circuit that includes a first evaporator and a second evaporator, wherein a bi-stable electromagnetic valve is provided that includes an entry line connected to an output of a condenser, a first output line connected to the first evaporator, and a second output line connected to the second evaporator. The valve is configured to fluidly connect the input line to either the first or the second output line, so that only one of the condensers is supplied with cooling fluid.

    [0004] The invention provides an additional improvement, an additional advantage or an alternative to the prior art.

    Purpose of the Invention



    [0005] The purpose of the invention is obtaining a home appliance having a valve in a cost-effective manner.

    [0006] To achieve the abovementioned purpose, the invention provides a home appliance in accordance with claim 1. The home appliance comprises an electromagnetic valve for a fluid flow comprising a valve chamber, an inflow line connected to valve chamber, a first outflow line connected to the valve chamber, at least one second outflow line connected to the valve chamber, a valve body displaceable in the valve chamber between more than one end positions; wherein at least one of the end positions corresponds to the at least one second outflow line to control flow of the fluid through the corresponding second outflow line; and that the first outflow line is always open to fluid outflow regardless of the position of the valve body. Thus, due to being an electromagnetic valve, it is achieved to have a valve in a cost-effective manner. It is also achieved that a valve selectively providing more than one outflow rates is obtained, particularly in a cost-effective manner. By using such a valve on a home appliance, a cost-effective home appliance is also obtained.

    [0007] In this context, "cost-effective" is in particular to mean relatively cheaper than other types of valves that provides selective outflows known in the art, for example a rotary valve.

    [0008] In a possible embodiment of the invention, the first outflow line may be fluidly connected to the valve chamber at a position except than the more than one end positions of the valve body. Thus, continues, in other terms uninterrupted, outflow through the first outflow line is realized regardless of the position of the valve body.

    [0009] In a possible embodiment of the invention, the valve body may have one end position that corresponds none of the first outflow line, the at least one second outflow line and the inflow line. Thus, although an electromagnetic valve is employed, a three-way valve with only one selectively controlled outflow line is obtained.

    [0010] According to an embodiment, the home appliance is a household cooling device, comprising the valve according to any one of the embodiment stated previously. Thus, a cost-effective and reliably working home appliance is obtained.

    [0011] The household appliance is in particular provided for storing and preferably tempering victuals such as beverages, wine, meat, fish, vegetables, fruits, milk and/or dairy products in at least one operating state, advantageously for the purpose of enhancing a keepability of the stored victuals. However the home appliance could also be embodied as a home appliance for warming and in particular for cooking victuals such as an oven, a cooker and/or a microwave. Advantageously, the home appliance is embodied as a home chiller appliance, which is in at least one operating state configured for cooling victuals. The home chiller appliance could in particular be embodied as a climate cabinet, an ice-box, a refrigerator, a freezer, a refrigerator-freezer combination and/or a wine cooler. However, the home appliance could also be embodied as a home appliance for storing items without any cooling function.

    [0012] The home appliance could in particular be embodied as a climate cabinet, an ice-box, a refrigerator, a freezer, a refrigerator-freezer combination and/or a wine cooler. However, the home appliance could also be embodied as a home appliance for storing items without any cooling function. The home appliance may have a storage space and may have at least one shelf in the storage space to accommodate items to be stored or to be processed in the home appliance.

    [0013] The storage space is in particular defined by an inner liner of the home appliance. The storage space is in particular a space inside the home appliance, which is provided for storing victuals. The storage space is in particular at least partly divisible into at least two storage areas, preferably a plurality of storage areas. The storage space may be selectively closed by a door.

    [0014] The walls of the storage space including the inner face of the door may be made of plastic, composite material, metal (stainless steel, aluminum etc.), painted metal (painted aluminum etc.) or any other material known in the art as a material used to form the chamber of a cooling device.

    [0015] The door may be attached to the chamber as rotatable around a pivot or as slidable toward or away from the chamber. For instance, the door may be hinged to the chamber. In another embodiment, the door may be attached to the chamber by a rail as slidable. The rail may be a telescopic rail or any rail system known as used on a cooling device for such a door.

    [0016] The shelf may be any platform allowing locating an item thereon. In an embodiment, the shelf may be a box type with a cover, or may be a container having an opening. Moreover, any shelf in the technical field known as door shelf or door bin having at least one wall may be used on the invention. The inner wall stated may be at least one of inner front wall, inner rear wall, inner bottom wall or inner top wall of the shelf.

    [0017] The item disposed in the cooling device may be food or a container containing food.

    [0018] According to the invention, the home appliance includes a cooling circuit with a refrigerant fluid, and the outflow lines are each connected to a corresponding outflow capillary tube. Thus, at least two outflow capillary including a continues-flow capillary is realized.

    [0019] According to the invention, the capillary tubes are connected to a single inlet of a heat exchanger, particularly an evaporator, of the cooling circuit. Thus, the refrigerant fluid with selectively more than one flow rate may be provided to the inlet of the heat exchanger. Thus, according to the energy load and need of the heat exchanger, the refrigerant fluid with desired flow rate may be provided to the heat exchanger corresponding to the need. As a result, a cost-effective and efficient home appliance may be obtained.

    [0020] In a possible embodiment of the invention, at least one of the capillary tubes may provide a different flow rate compared to at least one of the other capillary tubes. Thus, a further option to choose about the flow rate may be possible through the valve.

    [0021] In a possible embodiment of the invention, the inflow line may be connected to a drier or an inflow capillary tube connected to the drier. Thus, according to the energy need and/or the design of the home appliance, connection between the drier and the valve may be realized. It is possible to connect the inflow line directly to the drier or a capillary tube connected to the drier.

    [0022] Further advantages may become apparent from the following description of the drawing. In the drawing an exemplary embodiment of the invention is shown. The drawing, the description and the claims contain a plurality of features in combination.

    Detailed Description of the Invention



    [0024] In Fig. 1, a valve (30), specifically an electromagnetic bi-stable valve is presented as sectioned. The valve (30) has a cylindrical outer shell that comprises a solenoid coil (31) and an inner sleeve (33) and an outer sleeve (32) encompassing the coil (31) together with the inner sleeve (33). The cylindrical outer shell is in pipe-form and has an inner space. In this space, a valve chamber (36) is formed by covering the both ends of the space by two end bodies (34, 35). The valve chamber (36) is formed by the clearance kept between two end bodies (34, 35). On the faces of the end bodies (34, 35) facing each other, there are two magnets (37) as one for each, namely the first end body (34) and the second end body (35). The magnets (37) has a circular form with a hole on the center. Inside the hole, the first and second end bodies (34, 35) form a seat (42) for a valve body (41) that is a magnetic ball, for example a steel ball. The valve body (41) can move between the seats (42) on the end bodies (34, 35) as end positions (43) for the valve body (41). According to current flow in the coil (31), one of the magnet (37) provides pulling force and pulls the valve body (41) towards itself. Thus, the valve body (41) is located on the corresponding seat (42). The holes of the magnets (37) and the seats (42) correspond to the central axis of the cylindrical end bodies (34, 35).

    [0025] The valve (30) has one inflow line (38), one first outflow line (39) and a second outflow line (40). The inflow line (38) and the second outflow line (40) is formed through one of the second end body (35). The first outflow line (39) is formed through the first end body (34). The inflow line (38) is a channel between the valve chamber (36) and the outer face of the second end body (35). The end of the inflow line (38) opens into the valve chamber (36) at a point at least partially out of the area on the inner face (351) of the second end body (35) defined by the circular magnet (37). Thus, the valve body (41) never blocks the inflow line (38). Similarly, the first outflow line (39) is a channel between the valve chamber (36) and the outer face of the first end body (34). The end of the first outflow line (39) opens into the valve chamber (36) at a point at least partially out of the area on the inner face (341) of the first end body (34) defined by the circular magnet (37). Thus, the valve body (41) never blocks the first outflow line (39). On the other hand, the second outflow line (40) extends along the central axis of the second end body (35) and opens into the valve chamber (36) through the seat (42) on the second end body (35). Therefore, the second outflow line (40) can be controlled by moving the valve body (41) on or away from the seat (42).

    [0026] In fig. 2, a domestic refrigerator is presented as a home appliance (1) that has a freezer section (2) and a fridge section (3) covered by hinged doors (4) and having shelves (5) to support items. It has a cooling circuit (6) to cool the items in the refrigerator.

    [0027] The cooling circuit (6), as exemplified in fig. 3, has an evaporator (8) to take the heat inside the refrigerator, a compressor (9), a condenser (10), a drier (11), a valve (30) and fluid pipe (12). A refrigerant fluid flows through the cooling circuit (6), through pipe (12) and the other circuit members mentioned. The inflow line (38) of the valve (30) is connected to the drier (11) by an inflow capillary tube (14). The first and second outflow lines (39, 40) of the valve (30) are connected to an outflow capillary tube (7) corresponding to each one. Therefore, there are two parallel outflow capillary tubes (7). These outflow capillary tubes (7) are connected to a single inlet (13) of the evaporator (8). The fluid pipe (12) coming from the outlet (15) of the evaporator (8) is passed close to the outflow capillary tubes (7) to form an intermediate heat exchanger (16).
