Abstract
Description
Technical Field
[0001] This utility model relates to the field of laundry sink technology, and in particular to an artificial stone laundry sink that facilitates drainage. Background Technology
[0002] With the continuous improvement of living standards and the widespread availability of tap water in rural areas, people no longer wash their clothes by river or stream. They typically first hand-rub the particularly dirty parts of the clothes in a washing tub before washing or rinsing and spinning them in a washing machine. Traditional prefabricated washing tubs usually come in two types: precast cement and artificial stone.
[0003] Currently, due to limitations in mold-making capabilities and a lack of design experience, the drain holes in these laundry sinks are all located in the center of the basin. While this achieves drainage, it requires moving the clothes outwards to expose the central drain hole in order to completely empty the basin. Therefore, this application provides an artificial stone laundry sink with convenient drainage. Utility Model Content
[0004] The purpose of this application is to provide an artificial stone laundry sink that facilitates drainage, thereby solving the technical problem that existing artificial stone laundry sinks require the clothes in the sink to be moved to the sides to expose the central drain outlet in order to drain the water completely.
[0005] To achieve the above objectives, this application provides the following technical solution: an artificial stone laundry sink with convenient drainage, comprising a laundry sink, the laundry sink including a scrubbing section and a washing section, the washing section including a water storage tank integrally formed with the laundry sink, a drain hole being provided at one corner of the inner bottom of the water storage tank, the other three corners of the water storage tank decreasing in height towards the drain hole to form a gentle slope, the drain hole being located at the lowest point.
[0006] In a preferred embodiment of this invention, the inner bottom of the water storage tank is provided with multiple sets of straight drainage grooves in a fan shape, and the liquid outlet end of the multiple sets of straight drainage grooves near the drain hole communicates with the inner cavity of the drain hole. The straight drainage grooves are arranged parallel to the inclined inner bottom of the water storage tank.
[0007] In a preferred embodiment of this invention, a plurality of arc-shaped drainage grooves are sequentially arranged around the drainage hole. The plurality of arc-shaped drainage grooves are all connected to the inner cavity of the straight drainage grooves. The depth of the arc-shaped drainage grooves is consistent with the depth of the straight drainage grooves.
[0008] In a preferred embodiment of this invention, the scrubbing section includes a scrubbing groove with a scrubbing plate inclinedly arranged, and a liquid drain hole is provided at one corner of the scrubbing groove.
[0009] In a preferred embodiment of this invention, the laundry tub is provided with a placement groove, and the placement groove is provided with a liquid outlet, and the bottom of the inner cavity of the liquid outlet is lower than the bottom of the inner cavity of the placement groove.
[0010] In summary, the technical effects and advantages of this utility model are as follows:
[0011] This utility model has a reasonable structure. The bottom of the inner tank of the water storage tank forms a gentle slope, and the drain hole is set in the corner at the lowest point. When clothes are placed in the water storage tank, the drain hole is not easily blocked by the clothes because it is set in the corner. The gentle slope can guide the liquid to the drain hole, which is conducive to the drainage operation.
[0012] In this utility model, the bottom of the inner tank of the water storage tank is provided with multiple sets of straight drainage grooves in a fan shape, and the liquid outlet end of the multiple sets of straight drainage grooves near the drain hole is connected to the inner cavity of the drain hole, which is conducive to promoting drainage.
[0013] In this invention, the combination of arc-shaped and straight-line drainage grooves forms multiple flow paths, enabling water to converge at the drain outlet more quickly. This design reduces the time water stays at the bottom of the pool, helping the liquid to drain faster. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example: Reference Figure 1 and Figure 2 The artificial stone laundry sink shown is a convenient drainage sink, including a laundry sink 1. The laundry sink 1 includes a scrubbing section and a washing section. The washing section includes a water storage tank 3 integrally formed with the laundry sink 1. A drain hole 6 is provided at one corner of the inner bottom of the water storage tank 3. The other three corners of the water storage tank 3 descend in height towards the drain hole to form a gentle slope. The drain hole 6 is located at the lowest point.
[0022] The bottom of the inner tank of the water storage tank 3 forms a gentle slope, and the drain hole 6 is located in the corner at the lowest point. When clothes are placed in the water storage tank 3, the drain hole 6 is not easily blocked by the clothes because it is located in the corner. The gentle slope can guide the liquid to the drain hole 6, which is conducive to the drainage operation.
[0023] It is important to note the following: First, the slope should be set between 4° and 8°. An excessively steep slope will cause clothes to slide towards the drain hole 6 and block it; a slope that is too shallow will result in poor drainage. Second, a removable sealing cover can be installed inside the drain hole 6. Third, the water storage tank 3 of the laundry sink 1 can be equipped with two sets, such as... Figure 4 As shown.
[0024] As a preferred embodiment of this example, Figure 1 and Figure 2 As shown, multiple sets of straight drainage grooves 7 are arranged in a fan shape on the bottom of the inner tank of the water storage tank 3, and the liquid outlet end of the multiple sets of straight drainage grooves 7 near the drain hole 6 is connected to the inner cavity of the drain hole 6. The straight drainage grooves 7 are arranged parallel to the bottom of the inner tank of the inclined water storage tank 3.
[0025] After the clothes in the water tank 3 have been washed and the washing water has been drained, the clothes piled up in the water tank 3 need to be left to stand for a while so that the water on the clothes can fall to the bottom of the water tank 3 by gravity and move along the inclined inner bottom of the tank, and finally be discharged from the drain hole 6. Since the clothes are piled up together, multiple small and relatively sealed spaces are easily formed between the bottom clothes and the inner bottom of the tank. The washing water in this space can only be discharged slowly through osmosis. Therefore, a straight drainage groove 7 is set up so that the washing water in this space can enter the straight drainage groove 7 and finally be discharged outward through the drain hole 6, which helps to promote drainage.
[0026] It is important to note that: First, the width of the straight drainage groove 7 should be controlled between 2 and 4 mm. If the width is too small, drainage will not be able to be completed quickly and in a timely manner. If the width is too large, the accumulated clothes may cause blockage of the straight drainage groove 7. Second, the straight drainage groove 7 should be set parallel to the bottom of the inclined water storage tank 3 to avoid the groove from having a height difference, which may cause some liquid or stains to be trapped in the groove.
[0027] As a preferred embodiment of this example, Figure 3 As shown, multiple sets of arc-shaped drainage grooves 8 are arranged sequentially around the drainage hole 6. The multiple sets of arc-shaped drainage grooves 8 are all connected to the inner cavity of the straight drainage groove 7. The depth of the arc-shaped drainage groove 8 is consistent with the depth of the straight drainage groove 7.
[0028] The combination of the arc-shaped drainage groove 8 and the straight drainage groove 9 forms multiple flow paths, allowing the water flow to converge at the drain outlet more quickly. This design reduces the time the water stays at the bottom of the pool, which helps the liquid to drain faster.
[0029] It should be noted that the width of the arc-shaped drainage groove 8 should be controlled between 2 and 4 mm. If the width is too small, it will not be able to drain water quickly and in a timely manner. If the width is too large, the accumulated clothes will easily clog the arc-shaped drainage groove 8.
[0030] As a preferred embodiment of this example, Figure 1 As shown, the scrubbing section includes a scrubbing groove 2 with a scrubbing plate 4 inclinedly arranged, and a liquid outlet 5 is provided at one corner of the scrubbing groove 2.
[0031] Sometimes, to speed up the washing process, the water tank 3 is filled with washing water in advance. After each garment is washed, it is placed directly into the water tank 3 to immerse it. After all the garments have been washed, they are agitated for further cleaning. During the washing process, the wastewater containing detergent can be discharged directly through the drain hole 5, avoiding direct discharge into the water tank and contamination of the washing water, and avoiding increasing the number of times the washing water is used to clean the garments after washing.
[0032] It should be noted that the liquid outlet 5 is located near the corner of the baffle of the scrubbing groove 2, and the baffle can prevent wastewater from entering the water storage tank 3.
[0033] As a preferred embodiment of this example, Figure 1 As shown, the laundry tub 1 is provided with a placement groove 9, and the placement groove 9 is provided with a liquid outlet 10, and the bottom of the inner cavity of the liquid outlet 10 is lower than the bottom of the inner cavity of the placement groove 9.
[0034] The groove 9 can hold laundry soap, and the outlet 9 is used for draining liquid. The liquid enters the scrubbing groove 2 and is finally discharged from the drain hole 5.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
