Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the present invention. One skilled in the art, however, will understand that the following description merely illustrates a preferred embodiment of the invention and that the invention may be practiced without one or more of these details. In other instances, well known features have not been described in detail so as not to obscure the invention.

In accordance with one aspect of the present invention, a bowl 100 and 100' for a washing machine 400 is provided, as shown in FIGS. 4-5. The beakers 100 and 100' are primarily used in a cleaning machine 400, as shown in fig. 1-3, for filtering a water stream. Thus, according to another aspect of the invention, there is also provided a washing machine 400. The washing machine 400 can be used for washing dishes, chopsticks, dishes, knives, forks and other tableware, vegetables, fruits and the like in the environments of families, restaurants, hotels and the like. Thus, the washing machine 400 provided herein may be a dishwasher, a garden machine, or any other washing device. That is, the principle provided by the present invention can be applied in the case where a washing process of objects to be washed (dishes, vegetables, fruits, etc. described above) with water flow is required.

As described above, in order to circulate the water flow in the washing machine, a water returning chamber 420 is provided at the bottom of the washing machine, and referring to fig. 1 and 3, the water returning chamber 420 can collect water falling after washing the object to be washed. The water return chamber 420 is covered with a filter screen 410, and the filter screen 410 can prevent dirt in water from entering the water return chamber 420. The cups 100 and 100' are provided in the middle of the filter net 410, and the filter net 410 is gradually inclined downward from the periphery toward the cup 100, so that the filth filtered by the filter net 410 can flow into the cup 100 along with the water flow. After the washing machine 400 is stopped, the user can take out the cups 100 and 100' and pour the dirt therein.

The beakers 100 and 100 according to embodiments of the present invention will be described in detail with reference to fig. 1 to 5. Therein, solid and dashed arrows shown in fig. 3 schematically illustrate the flow directions of water and gas within the cup 100 and the washer 400, respectively.

As shown in fig. 4, the carrying cup 100 may include a cup frame 200 and a filter body 300. The cup frame 200 may include a ring-shaped cup rim frame 210 and a cup frame 220 connected to a lower portion of the cup rim frame 210. For example, the cup frame 220 and the rim frame 210 may be separately manufactured and then connected together by using a connection method such as bonding, welding, and the like. Alternatively, the cup frame 220 and the rim frame 210 may be integrally formed. The cup frame 220 may be connected to an outer periphery of the rim frame 210, an inner periphery of the rim frame 210, or a position between the outer periphery and the inner periphery.

Preferably, the cup frame 220 may be connected to an inner circumference of the rim frame 210. Thus, the cup 100 forms a step between the cup body frame 220 and the rim frame 210, so that the rim frame 210 can protrude from the cup body frame 220. The cup holder frame 210 is clamped on the filter screen 410 to fix the lifting cup 100. Meanwhile, it is convenient to provide the air inlet 241, that is, as will be mentioned later, to provide the air inlet 241 on the bottom surface of the rim skeleton 210.

The filter body 300 may cover the cup frame 220. The filtering accuracy of the filter body 300 can be selected by those skilled in the art according to the dirt inside the washing machine 400, for example, different mesh numbers of filter screens are used. Illustratively, the filter body 300 may include one or more layers of filter bodies, and when the filter body 300 adopts a multi-layer structure, it may include any kind of filter bodies, which may be the same or different. Therefore, the filter body 300 may cover the inner side of the cup body frame 220 and/or cover the outer side of the cup body frame 220.

The rim skeleton 210 may have a plurality of partitions 211 disposed at intervals in a circumferential direction of the lifting cup 100. The thickness of the partition 211 in the radial direction may be greater than the thickness of the other portions of the rim skeleton 210. A water inlet 230 may be disposed between adjacent partitions 211. The partition 211 may be provided with an exhaust passage. The exhaust passages may include, for example, first exhaust passage 240 and/or second exhaust passage 250. The inlet of the exhaust channel may be located at a lower portion of the rim skeleton 210. The inlet ports of the exhaust passage may include, for example, inlet ports 241 and 251. The exhaust port of the exhaust passage may be located at an upper portion of the rim skeleton 210. The exhaust ports of the exhaust passage may include, for example, exhaust ports 242 and 252. For example, an exhaust passage may be provided on each of the partitions 211. Alternatively, an exhaust passage may be provided only in a part of the partition 211. The cross-section of the exhaust channel may have any shape, preferably, it may be circular or square.

The washing machine 400 provided according to the present invention may include a return chamber 420, any of the cups 100 described herein, and a filter screen 410. The water return chamber 420 may be provided on a body base of the washing machine 400. The filter screen 410 may be planar or curved, and may have dense meshes on its surface, and those skilled in the art can select the mesh number of the filter screen 410 according to the dirt condition in the washing machine 400 to achieve the desired filtering accuracy. The filter screen 410 may cover the top surface of the return water chamber 420. Preferably, the filter screen 410 may be fixed on the base of the machine body by a snap. The cup body frame 220 of the lifting cup 100 is accommodated in the water return chamber 420, and at least a portion of the cup rim frame 210 can extend above the filter screen 430, so that at least a portion of the water inlet 230 can extend above the filter screen 430. Thus, the water flowing into the return chamber 420 may pass through the filter screen 410 and the cup 100. Preferably, the rim skeleton 210 may be 5-40 mm higher than the filter screen 410, so as to facilitate the user to take the beverage with his hand. The inlet of the exhaust passage may be located below the filter screen 410. The water inlet 230 and the exhaust port of the exhaust passage may be located above the filter screen 430.

For example, as shown in fig. 1, the bottom surface of the backwater chamber 420 may have a concave cup lifting chamber 421. The mug 100 can be inserted into the mug cavity 421 and spaced apart from a sidewall of the mug cavity 421. In this way, a buffer zone can be formed in the lower portion of the cup chamber 421 where the water flow can be substantially separated from the gas. The cup lifting chamber 432 may have a water return port 422 and a water discharge port 423 at a lower portion thereof. The water return port 422 may be connected to a water suction pump, and the water suction pump may pump water through the water return port 422 to spray the object to be cleaned. The drain 423 may be connected to a sewage drain port, and may drain all the water inside the washing machine 400 after washing. The water flow fully separated from the gas in the buffer zone can be conveyed to the water suction pump through the water return port 422 at the bottom, so that the influence on the working performance caused by the air suction in the pump is avoided.

As shown in fig. 1, when the washing machine 400 washes an object to be washed, water flow and dirt accompanied by air may flow from a chamber (e.g., a washing chamber) above the filter screen 410 to the filter screen 410. The water and gas filtered by the filter screen 410 may enter the return chamber 420 and then the cup chamber 421. A portion of the dirt that fails to pass through the filter screen 410 and a portion of the water that does not pass through the filter screen 410 in time may be primarily filtered through the inlet 230 of the cup 100, isolating the dirt with a larger size from the inlet 230. Dirt, water flow and gas passing through the water inlet 230 may enter the cup 100 and then be filtered again by the filter body 300. Water and gas passing through the filter body 300 can enter the cup cavity 421, while contaminants that fail to pass through the filter body 300 remain in the cup 100. While another portion of the filth which fails to pass through the filter screen 410 and the water inlet 230 adheres to the surface of the filter screen 410, and when the amount of the filth adhered thereto is large, the meshes of the filter screen 410 may be clogged. Because the water flow and the gas continuously enter the water return cavity 420, the air pressure in the water return cavity 420 is higher than the air pressure in the cleaning cavity, and the gas can enter the exhaust passage through the air inlet on the lifting cup 100 and is exhausted into the cleaning cavity through the exhaust port, as shown in fig. 3, the air pressure in the water return cavity 420 is the same as the air pressure in the cleaning cavity, so that the gas in the water return cavity 420 is prevented from being too high to cause the gas to block the filter screen 410 for filtering, and the filtering performance of the filter screen 410 is reduced. The cup 100 may be located in the cup chamber 421, the water may be collected from the periphery of the water return chamber 420 to the cup chamber 421, and the gas flows to the cup 100 along with the water, so that the gas is easily discharged from the exhaust passage. Through the arrangement, gas can be conveniently discharged through the exhaust channel, and the air inlet is arranged at the lower part of the lifting cup 100, so that the air inlet cannot be blocked due to the fact that the filter screen 410 is blocked or the water curtain passing through the filter screen is blocked, smooth exhaust is ensured, and the cleaning performance of the cleaning machine 400 is improved.

By arranging the water return port 422 and the water discharge port 423, water in the cup chamber 421 can be pumped away by a water pump (not shown) through the water return port 422 for cleaning again, and the water flow is repeatedly recycled, so that the water consumption of the cleaning machine 400 is greatly reduced. When the washing machine 400 is washed, the water flow may be discharged to the outside of the washing machine 400 through a drain pump (not shown) via the drain port 423. In some cases, the water can be drained by gravity without a suction pump. Therefore, the gas is discharged in time, and the gas is prevented from entering the water pump to damage the water pump, thereby affecting the cleaning performance of the cleaning machine 400.

Preferably, as shown in fig. 1 to 5, the exhaust port of the exhaust passage may be located on the inner circumferential surface of the rim skeleton 210, i.e., the exhaust port 242 and/or the exhaust port 252 may face the inside of the beaker 100. Therefore, when water flow and dirt on the filter screen 410 flow from the periphery of the lifting cup 100 to the lifting cup cavity 421, the water flow and the dirt enter through the exhaust port and block the exhaust channel, and smooth exhaust is ensured.

For example, as shown in fig. 1-5, the exhaust passage may include a first exhaust passage 240. The first exhaust passage 240 has an intake port 241 and an exhaust port 242. The air inlet 241 may be located at a lower portion of the rim skeleton 210 and at an outer side of the filter body 300. Therefore, the gas in the water return cavity 420 is discharged through the first exhaust channel 240, and the smooth exhaust of the water return cavity 420 is ensured.

Preferably, as shown in fig. 1 to 5, the inlet 241 of the first exhaust channel 240 may be located at the bottom surface of the rim skeleton 210. Thus, the distance between the cup lifting cavity 421 and the air inlet 241 is the shortest and the most unobstructed, and the air exhaust is ensured to be unobstructed. In addition, it is also possible to space the exhaust port 242 and the intake port 241 a sufficient distance to ensure that, when installed, the exhaust port 242 is located above the filter screen 410 and the intake port 241 is located below the filter screen 410.

For example, as shown in fig. 1 to 5, a cross beam 212 may be connected between upper portions of adjacent spacers 211. The cross beam 212, adjacent spacers 211 may surround to form the water inlet 230. The cross-section of the water inlet 230 may be of any size and shape, for example circular or elongated. By providing the cross beam 212, the overall structure of the cup 100 can be more stable. In addition, the cross beam 212 can also be used as a grip for taking out the cup 100, i.e. a user can insert a fingertip into the water inlet 230 to lift the cross beam 212 upwards to take out the cup 100.

Illustratively, as shown in fig. 3-5, the filter body 300 may include a coarse filter body 310 at an inner layer and a fine filter body 320 at an outer layer. For example, the coarse filter 310 may be located inside the cup frame 220, and the fine filter 320 may be located outside the cup frame 220. The fine filter body 320 may have higher filtering accuracy than the coarse filter body 310, and may filter finer contaminants. The water and dirt in the cup 100 may be filtered by the coarse filter 310 and then by the fine filter 320, and the filtered water may enter the water return chamber 420. Through this kind of setting, can realize two-stage filtration in carrying 100 cups, coarse filtration body 310 and fine filtration body 320 can the cooperation work, filters not unidimensional filth respectively, and increase filter area improves the filter effect to can guarantee that rivers flow out smoothly and carry cup 100.

In the embodiment where the filter body 300 may include the coarse filter body 310 at the inner layer and the fine filter body 320 at the outer layer, as shown in fig. 5, the second air discharge passage 250 may be further provided at the partition 211. The inlet 251 of the second exhaust passage 250 may be located at a lower portion of the cup rim skeleton 210 between the coarse filter body 310 and the fine filter body 320. The exhaust port 252 of the second exhaust passage 250 may be located at an upper portion of the rim skeleton 210. In this way, the gas between the fine filter 320 and the coarse filter 310 can be easily discharged through the second gas discharge passage 250, and particularly, when the coarse filter 310 has a large amount of contaminants adhered thereto, the mesh of the coarse filter 310 is blocked, and the gas can be timely discharged to prevent the gas pressure between the fine filter 320 and the coarse filter 310 from being excessively high, which may result in the deterioration of the filtering performance of the fine filter 320 and the coarse filter 310. The cleaning performance of the cleaning machine 400 is improved.

Only the differences between the second exhaust passage 250 and the first exhaust passage 240 are described above, and for the parts of the second exhaust passage 250 that are the same as or similar to the first exhaust passage 240, the descriptions of the corresponding parts above can be referred to, and the descriptions thereof will not be repeated herein for brevity. It should be noted that the second exhaust passage 250 may coexist with the first exhaust passage 240, i.e., the cup 100' may have the first exhaust passage 240, or the second exhaust passage 250, or both the first exhaust passage 240 and the second exhaust passage 250.
