Definitions

• This invention extends to a water filter device and more particularly relates to a water filter device mounted in the cold storage room of a household electric refrigerator.
• Electric refrigerators especially refrigerators with an automatic ice maker, must feed the external water source of the refrigerator via guide tubes into the automatic ice making device to prepare ice cubes.
• the position of the conventional water filter devices is usually located within the engine room for the assembly of the compressor below behind the cold storage room of the refrigerator. Since the contained filter cylinder must be replaced after the water filter device has been used for a while, the user first has to dismantle the back cover of the engine room before he can disassemble the water filter device, whereby the replacement of the filter cylinder is very cumbersome.
• U.S. Patent US7,056,435B2 discloses a novel water filtering device as shown in Figure 1 ( Figure 3 of the specification of U.S. Patent US7,056,435B2).

• the cover 24 When the cover 24 is in the closed position, the filter cylinder 22 is held by the support of the cover 24 in the operating position.
• the water filter device is placed at a location easily accessible by the user in the cold storage room, it may also result in an inadvertent contact of the cover 24 by the user that the cover 24 drops together with the filter head 20 and the filter cylinder 22 from its use position and causes unnecessary difficulties, or that the user would like to open only the cover 24 to view the operating state of the filter head 20 and filter cylinder 22, and they do not want to drop from their operating position.
• the current design can not realize these functions.
• the aim of this invention is to provide a water filter device which is both easy to assemble and disassemble and ensures safe use.
• the water filter apparatus of an electric refrigerator of one embodiment of this invention comprises a housing fixed to the cabinet body, a filter head connecting the water inlet pipe and water outlet pipe, a removable filter cylinder connected to the filter head, and a rotatable between open position and closed position Cover, wherein the filter head is fixed by a fastening device on one end of the housing and the cover is movably connected to one end of the housing.
• the described fastening device comprises positioning holes mounted on one end of the housing and elastic cantilevers mounted on the filter head, these elastic cantilevers being inserted into these positioning holes.
• a further improvement of this invention is that the described housing has a ceiling which can be mounted on the cabinet body of the refrigerator, as well as extending from both sides of the ceiling downwardly extending side walls, said ceiling and said side walls a receiving space for receiving form the filter cylinder.
• one end of the described housing has a downwardly extending jaw portion and an end of the described cover over an axis of rotation, said axis of rotation and claw portion coordinately coupling the cover to said housing.
• the described cover has a supporting device for supporting the positioning of the filter cylinder in the receiving space, wherein the described supporting device comprises at least one vertical support disk, this support disk, when the cover is in the closed position, supports the side surface of the filter cylinder, and the shape of the head end of the described support disk coincides with the outer contour of the filter cylinder.
• the efficiency of this invention is as follows: Since the water filter device is disposed in the refrigerated storage compartment and the cover of the water filter device can be rotated between the open position and the closed position, disassembly of the filter cylinder is facilitated. Furthermore, the filter head is secured by a mounting device on the housing, and the cover is movably connected to the housing, so that a rotation of the cover can not cause unintentional falling off of the filter head and filter cylinder.

• the filter head 42 is connected to the water inlet pipe 420 and the water outlet pipe 422, respectively.
• the water source flows via the water inlet tube 420 into the filter cylinder to perform the filtering. After filtering, the water flows through the water outlet pipe 422 again.
• the housing 40 has a ceiling and two side walls each extending downward from both sides of the ceiling, this ceiling and the side walls together forming an internal receiving space 408 and the filter cylinder 43 therein Recording room 408 is recorded.
• One end of the ceiling of the housing 40 has two positioning plugs 404.
• the other end has a through hole 406 into which a screw can be screwed.
• the ceiling of the housing 40 can be mounted on an external element, for example, the use of the refrigerator.
• a positioning hole 400 is provided on the ceiling of the housing 40 .
• two elastic cantilevers 424 are mounted on the filter head 42, each extending obliquely upwards and downwards. These two elastic cantilevers 424 are respectively inserted into the corresponding positioning holes 400, whereby the filter head 42 is mounted on one end of the housing 40.
• a clamping hook 402 At the lower end of the housing 40 extends downwards a clamping hook 402 with a U-shaped end.
• the cover 41 has an upwardly extending clamping closure part 410.
• On this clamping closure part 410 is a hinge 412 which is inserted into the U-shaped part of the clamping hook 402. This hinge 412 can rotate relative to the clamping hook, causing a rotational movement of the cover 41 between the open position and the closed position.
• two vertical support discs 414 are attached on the cover 41. During rotation of the cover 41 to the closed position, these support disks 414 support the side surfaces of the filter cylinder 43.
• the head end of the support disks 414 has a negative arc. The radian of this circular arc coincides with the radian of the round filter cylinder 43, whereby the positioning of the filter cylinder 43 in the receiving space 408 is supported.
