Description
Technical Field
[0001] The utility model relates to the technical field of refrigerator condensed water treatment, in particular to an anti-blocking water receiving box for a refrigerator and a refrigerator having the same. Background Art
[0002] During the installation or use of the refrigerator, some granular or linear debris will fall from the inner liner of the refrigerator or directly from the items. These debris will be discharged through the drain hole along with the condensed water. However, the drain holes of refrigerators currently on the market are all exposed single round holes without protection. These granular or linear debris may be large or small in shape, and it is easy to block the drain hole when discharged through the drain hole, resulting in an increase and accumulation of condensed water in the refrigerator. The long-term accumulation of condensed water will lead to the production of some microorganisms such as bacteria and mold, which will affect the service life of the items in the box and increase the risk of disease transmission. Utility Model Content
[0003] In order to solve the above problems in the prior art, the utility model provides an anti-blocking water receiving box for a refrigerator and a refrigerator having the anti-blocking water receiving box for a refrigerator, which will be advantageous.
[0004] To achieve the above-mentioned purpose, according to one aspect of the utility model, there is provided an anti-blocking water collecting box for a refrigerator, which includes a sink bottom plate and a sink enclosure plate which together form a condensed water sink, wherein the sink bottom plate is high at both ends and low in the center in the longitudinal direction, and the sink bottom plate is provided with an anti-blocking tooth structure and a sink drain pipe with a central tube hole at its center position, the anti-blocking tooth structure includes a plurality of L-shaped sink anti-blocking teeth which are arranged in a ring and are upside down and have vertical and horizontal portions, the vertical portions of the plurality of sink anti-blocking teeth all protrude inwardly from the inner wall of the central tube hole to form an inner flow channel with a diameter smaller than the central tube hole at its center, the horizontal portions of the plurality of sink anti-blocking teeth all protrude upwardly from the upper surface of the sink bottom plate and are arranged radially in a trumpet shape to form a drainage channel connected to the central tube hole between two adjacent sink anti-blocking teeth.
[0005] In the utility model, since the two ends of the sink bottom plate are high and the center is low to form an inclined surface, the condensed water will immediately flow down to the central tube hole in the center of the sink bottom plate after entering the condensed water sink, and will not cause accumulation; due to the setting of the anti-blocking tooth structure, the condensed water can flow away through the drainage channel and the central tube hole while blocking the linear objects in the condensed water, the particles in the condensed water whose shape is larger than the width of the narrowest part of the drainage channel, and the directly fallen objects whose shape is larger than the diameter of the inner flow channel, so as to avoid clogging the sink drain pipe.
[0006] Further, the lower end of the sink drain pipe protrudes downward from the lower surface of the sink bottom plate.
[0007] Through the above-mentioned structural arrangement, condensed water can be better discharged from the anti-blocking water receiving box through the sink drain pipe.

[0017] The above-mentioned structural arrangement can prevent condensed water from entering the return air pipe hole.
[0018] Furthermore, the narrowest width D1 of the drainage channel is 1 mm; the diameter D2 of the inner flow channel is 5.1 mm; and the diameter D3 of the central tube hole is 5.5 mm.
[0019] Through the above-mentioned structural setting, particles smaller than 1mm in the condensed water will be smoothly discharged through the drainage channel and the central tube hole, while particles with an appearance greater than or equal to 1mm will be blocked by the two adjacent sink anti-blocking teeth to avoid entering the sink drain pipe and causing blockage. Through the above-mentioned structural setting, if there are objects with an appearance less than 5.1mm from top to bottom, they will be discharged through the inner flow channel; and objects with an appearance greater than 5.1mm will be supported by the sink anti-blocking teeth and will not fall into the central tube hole through the inner flow channel; objects with an appearance equal to 5.1mm will be supported by the connection between the horizontal and vertical parts of the sink anti-blocking teeth, and will not affect the flow of condensed water from the drainage channel into the central tube hole, thereby achieving an anti-blocking effect.
[0020] Furthermore, the anti-blocking water collecting box for the refrigerator is formed by integral injection molding, and has high production efficiency and low cost.
[0021] According to another aspect of the utility model, a refrigerator is provided, which has the above-mentioned anti-blocking water receiving box for the refrigerator, wherein the inner tank installation limit groove of the anti-blocking water receiving box is suitable for plugging in the inner tank water sink plug plate of the refrigerator inner tank, and the sink drain pipe of the anti-blocking water receiving box is suitable for draining out the condensed water in the condensed water sink of the anti-blocking water receiving box.
