Detailed Description

Example one

As shown in fig. 1 to 4, a filtering device for a dish washer comprises a first filtering portion 101, wherein first filtering nets 103 are uniformly distributed on the side wall of the first filtering portion 101, openings are formed in the upper end and the lower end of the first filtering portion 101, and the first filtering nets 103 are fine filtering. The lower part of the first filtering part 101 is provided with a collecting box 102, and the bottom of the box is uniformly provided with through holes for filtering water. The residue in the first filter part 101 falls into the collecting box 102, so that the collecting box 102 can be detached when the first filter part 101 needs to be cleaned, and the first filter part 101 is convenient to clean at two ends. The filter further comprises a second filter part 201, and when the filter is installed, the second filter part 201 is placed in the first filter part 101. Be equipped with the slot on first filter house 101, be equipped with the cutting on second filter house 201 to can peg graft second filter house 201 and first filter house 101 together, thereby be convenient for carry out the dismouting when the clearance. The second filter screen 202 is uniformly distributed on the side wall of the second filter part 201, so as to form coarse filtration. An opening is formed in the upper end of the second filter part 201, so that other components can be conveniently installed. A bottom shaft 207 and an annular filter screen 206 are installed at the bottom of the second filter portion 201. Specifically, the lower portion of the bottom shaft 207 is mounted on a bearing centrally provided at the bottom of the second filter portion 201. The ring filter 206 forms a coarse filter together with the second filter 202.

Since the second filter portion 201 is often adhered with large-sized residues, the residues block the second filter 202, and the filtering performance is reduced. To solve this problem, a combing mechanism is provided in the second filter part 201, and residues adhered to the second filter 202 can be cleaned by the combing mechanism. In order to be able to provide a power source for the comb mechanism, the filter device is further provided with a conical mounting 305, wherein a transmission mechanism is arranged in the conical mounting 305, and the comb mechanism is connected with the transmission mechanism. In order to facilitate cleaning, a support frame 313 is fixedly connected to the bottom of the conical mounting seat 305, and during mounting, the support frame 313 is inserted into a slot formed in the second filter part 201. The transmission mechanism is connected with a blade shaft 306, a pair of blade shafts 306 are respectively arranged outside the conical mounting base 305, blades 308 are fixedly mounted on the blade shaft 306, and along with the movement of water flow, the water flow drives the blades 308 to rotate, so that the blade shaft 306 rotates.

Specifically, as shown in fig. 5, the transmission mechanism includes a transmission shaft 307, both upper and lower ends of the transmission shaft 307 extend out of the tapered mounting seat 305, and the middle portion of the transmission shaft 307 is mounted on a bearing provided in the tapered mounting seat 305. Blade shaft 306 is connected to drive shaft 307 through bevel gear set 311. When the water flow rotates the blades 308, the blade shaft 306 rotates, and the transmission shaft 307 also rotates. The carding mechanism comprises a stirring shaft 208, and a plurality of stirring fins 203 are fixedly connected to the stirring shaft 208. The end of the stirring fin 203 away from the stirring shaft 208 is provided with a plurality of stainless steel elastic sheets 205 at intervals. When the stirring shaft 208 rotates, the stirring fins 203 rotate, and the stainless steel elastic sheet 205 removes residues adhered to the second filter screen 202. A plurality of kidney-shaped holes 204 are formed in the agitating fin 203 to reduce resistance when the agitating fin 203 rotates.

In order to facilitate the disassembly of the device when the device needs to be cleaned, the lower ends of the bottom shaft 207 and the stirring shaft 208 and the lower end of the transmission shaft 307 and the upper end of the stirring shaft 208 are connected through splines, namely, an inner spline and an outer spline are processed, so that the stirring shaft 208, the bottom shaft 207 and the transmission shaft 307 are conveniently connected through insertion. During cleaning, the conical mounting base 305 and the second filter part 201 can be separated, the transmission shaft 307 and the stirring shaft 208 are disconnected, the stirring shaft 208 and the bottom shaft 207 are disconnected, and the second filter part 201 is detached from the first filter part 101, so that the overall cleaning can be performed.

Since large-sized residues enter the second filtering portion 201, the residues are not easily swept away by the agitating fins 203, and thus the large-sized residues need to be shredded. Specifically, a funnel cover 301 is inserted into the first filter part 101, so as to guide the water flow to the second filter part 201. A cone-shaped guide cover is inserted into the funnel cover 301. The conical guide cover comprises an upper cover body 303 provided with a second through hole and a lower cover body 302 provided with a leak hole 304. A cutter hole 312 is arranged between the upper cover 303 and the lower cover 302. The lower end of the cutter shaft 310 is connected with a transmission mechanism, namely, the lower end of the cutter shaft 310 is connected with the upper end of the transmission shaft 307 through splines, and the upper end of the cutter shaft 310 is connected with a bearing arranged on the upper cover 303. The drive shaft 307 can drive the cutter shaft 310 to rotate. The cutter shaft 310 is provided with a cutter, and the edge of the cutter extends out of the cutter hole 312. Specifically, the upper housing 303 and the lower housing 302 are connected by a "U" shaped block 309. The pair of U-shaped blocks 309 are symmetrically disposed between the upper housing 303 and the lower housing 302, so that a cutter hole 312 is formed between the upper housing 303 and the lower housing 302, and the cutter does not touch the U-shaped blocks 309 when the cutter rotates. The large-sized residues slide downwards along with the conical guide cover and are cut off by the cutter, and because the through holes II are uniformly distributed on the upper cover body 303, water flow can pass through the through holes, the large-sized residues cannot pass through the through holes, and the residues cut off by the cutter can pass through the through holes 304 and then enter the second filtering part 201 for filtering.

Example two

The present embodiment is different from the embodiment in that the collecting box 102 is screwed to the lower end of the first filter part 101. As shown in fig. 6, a filter 104 is provided in the collection box 102. The filter sheet 104 is provided with filter holes. The filter sheet 104 and the collecting box 102 are arranged independently, so that the filter sheet 104 can be replaced by a new one conveniently, and the filter sheet 104 with different filter pore diameters can be selected according to actual conditions.
