Embodiment Construction

[0016] reference figure 1 with 2 Some features of the illustrated filter are similar to those disclosed in GB-B-2251547, which is incorporated herein by reference. Therefore, the filter 10 includes a support frame 11 composed of a single piece molded of plastic, such as polypropylene, having a generally rectangular and curved main wall 12 and an outwardly projecting upper end wall 14. The upper end wall 14 People can grasp the filter when putting the filter in or taking it out of the pot, and act as a baffle to prevent water from flowing out of the top of the filter when pouring water out of the pot. The upper part of the main wall 12 has an opening, which is divided into three separate parts 15 by an integral transverse rib. Each part is covered by a nylon filter screen 17, which is fixed in the frame during molding. The diameter of its holes is about 50 μm. reference image 3 , The picture shows a jug with a common plastic jug body. For example, the plastic is acetal copolymer ...

Abstract

A filter (10) for use in a water heating vessel, such as an electric kettle, to filter sedimentary material in the water includes a scale collector (25), for example in the form of a compacted mesh block, carried on the filter. The block can be supported by a carrier member (27) permanently or detachably mounted on the filter frame, preferably towards an end of the filter closest to the bottom of the vessel.

Description

Technical field [0001] The present invention relates to replaceable filters for water heaters, such as electric kettles, coffee pots and the like. Background technique [0002] Replaceable filters for removing scales and the like in kettles are known. For example, British Patent GB-B-2251547 discloses such a replaceable filter for electric kettles. The filter includes a plastic frame, the plastic frame has an opening covered by a fine filter, the fine filter is located in the water pot body of the pot and covers the water outlet, therefore, when the hot water in the pot is poured from the water outlet The strainer that flows through the filter when it comes out. The inside of the pot body and the frame of the filter are provided with mutually cooperating devices, so that the filter can be replaced in the pot in a sealed manner. In this way, the filter can be slid into the kettle body and kept in a proper position in the kettle body, and the filter can be easily removed by the rev...
