Description

A collection and filtering device Technical Field

[0001] The utility model relates to the field of washing machine parts, in particular to a collecting and filtering device. Background Art

[0002] The water inlet of the existing pulsator washing machine on the market is set at the upper or lower position inside the inner drum to achieve collection. As a result, the water inlet flow is low and the collection and filtering capacity is reduced. Due to the limited position of the upper or lower collecting water inlet, it is inevitable that it cannot collect water during high, medium and low water level washing and rinsing processes. The upper or lower collecting water inlet of the filtering device depends on the rotation of the impeller and the direction of the water flow containing clothes is not directly facing the water inlet, and the permeability is inevitably low. The impeller depends on the collection and filtering devices of various design structures arranged in the lifting ribs of the drum washing machine. Due to insufficient water inlet flow and too small impact force when encountering water, various sealing doors of the water inlet are difficult to open, resulting in the failure of the previously designed collection and filtering devices to be actually applied on the washing equipment. As a result, the current drum washing machine on the market still does not have a collection and filtering device. The original water consumption is small to achieve the collection and filtering function of the tumbling washing method, which is missing, and the rinsing effect is poor with less water, which inevitably reduces the final cleaning capacity of the clothes. The main problem is that there is no practical application of the collection and filtering device with a water inlet design structure along the rotation direction of the inner drum in the current market. Technical issues

[0003] There is currently no practical application of a collecting and filtering device with a water inlet design structure along the rotation direction of the inner drum in the market. The main reason is that the design of the collecting and filtering device realizes the side collection of the water inlet (along the rotation direction of the inner drum), that is, the rotation direction of the inner drum needs to ensure the closing force of the sealing door to prevent the leakage of collected pollutants, which causes the inner drum to rotate and encounter water to open the sealing door, and at the same time enhance the water flow rate. The large permeability has become an effective solution to the current collection and filtering device in the impeller and drum washing machine arrangement. At the same time, the water inlet of the collecting and filtering device is in the narrow space between the inner and outer drums, and the amount of water encountered is small and the flow rate is low, so it is difficult to achieve efficient collection capacity. There is also a problem that the arrangement of the sealing door structure leads to insufficient torque when encountering water, which makes it difficult to open the sealing door.

[0031] The width of the end of the arc-shaped plate 21 close to the fluid inlet is set to be equal to the width of the side of the arc-shaped plate 21 close to the fluid inlet.

[0032] The central angle of the arc of the arc plate 21 is 90 degrees.

[0033] It also includes two parallel side panels 23, both of which are fixedly connected to the collection box 1, and the arc plate 21 is arranged in the area between the two side panels 23, and the two sides of the arc plate 21 are respectively connected to the two side panels 23 to form a flow channel, and the guide channel 24 is connected to the fluid inlet.

[0034] The guide structure is an annular guide ring plate 25, which is open. The opening at one end of the guide ring plate 25 is larger than the opening at the other end. The end with the smaller opening on the guide ring plate 25 is the small guide end, and the other end is the large guide end. The small guide end is fixedly connected to the collection box 1 and connected to the fluid inlet.

[0035] In one embodiment, the inner area of ​​the collection box 1 is a filtration collection area, and the fluid inlet and the fluid outlet are both connected to the filtration collection area;

[0036] The fluid inlet is sealed with a one-way opening sealing door which is opened due to fluid impact and can be automatically closed. The one-way opening sealing door is arranged inside the collection box 1. Modes for Carrying Out the Invention

[0037] In another embodiment, a filter mesh bag is connected to the fluid inlet, and a mesh bag constriction structure is provided in the collection box 1. The mesh bag constriction structure includes two long strip constriction columns 13 arranged parallel to each other, and the two ends of the two constriction columns 13 are respectively connected to the two ends of the collection box 1, and the filter mesh bag 14 is arranged between the two constriction columns; the fluid outlet is arranged on the end of the filter mesh bag 14 away from the fluid inlet, and the filter mesh bag 14 is arranged in the collection box 1.

[0039] The collecting box 1 is arranged on the inner drum 9 of the washing machine, and the one-way opening sealing door is an elastic plate. The washing machine is a dual-power washing machine. The washing machine can also be a drum washing machine. Industrial Applicability

[0040] When in use, the utility model is embedded in the inner drum 9 from the mounting port on the inner drum 9, the fluid inlet is located in the area between the inner drum 9 and the outer drum 10, the collection box 1 and the inner drum 9 are detachably connected through the connecting shell, and an appropriate diversion structure is selected according to the setting direction of the fluid inlet. For example, if the fluid inlet is set toward the outer drum 10, the arc plate 21 and the side plate 23 are selected, and the diversion channel 24 is set toward the circumferential direction of the inner drum 9. If the fluid inlet is set toward the circumferential direction of the inner drum 9, the diversion ring plate 25 is selected. When the inner drum 9 rotates, the fluid inlet is provided with a diversion structure, and the water flow in the washing machine is adjusted. The relative movement direction is facing the fluid inlet or the diversion channel 24. Since the washing machine is cleaning clothes, the cotton wool on the clothes is mixed in the water flow, the inner drum 9 rotates, and the water flows through the diversion structure to the fluid inlet. The water flow impacts the one-way opening sealing door on the collection box 1, causing the one-way opening sealing door to open, or causing the one-way opening sealing door to open to a larger extent, which is conducive to increasing the water flow rate entering the filtration and collection area from the fluid inlet. When the water flows from the fluid inlet into the filtration and collection area of ​​the collection box 1 and flows out from the fluid outlet, the fluid outlet is provided with a filter screen to realize the collection and filtration of the cotton wool.

[0041] The utility model is arranged in the narrow space between the inner cylinder 9 and the outer cylinder 10. Under the basic condition that the impact force of the inner cylinder 9 encountering water is weak in the existing technology, the opening ability of the one-way opening sealing door is enhanced, the water flow rate is increased, and it is beneficial to the efficient collection of hair, lint and pollutants in the water flow.
