Description

Self-cleaning structure of rear filter screen of washing and drying integrated machine Technical Field The invention relates to the technical field of filter screen flushing, in particular to a self-cleaning structure of a rear filter screen of a washing and drying integrated machine. Background The washing and drying integrated machine is a novel washing machine which is added with a drying function on the basis of a full-automatic washing machine and integrates the functions of washing, drying and the like. After the washing and drying integrated machine is used for washing clothes, the washed clothes can be directly dried, loose fuzzes on the clothes often enter a drying device along with air in the drying process, and therefore the normal operation of a heat exchange system is affected. The filtering structure is generally inserted into the air inlet end of the drying device, so that the heat exchange structure is prevented from being blocked by the flock. At this time, the fan is installed on the air duct of the air outlet part of the drying device, and the space at the place is relatively small, and the fan with larger power/volume cannot be installed, so in the new design, the fan is installed in the drying device and the rear end air duct, as shown in fig. 1. After the design, the space for installing the filter screen of the drying device is greatly reduced or the installation space cannot be vacated, so that the filter screen is designed in the air duct at the rear end. The invention provides a self-cleaning structure of a rear filter screen of a washing and drying integrated machine, which aims at needing to clean the filter screen regularly. Disclosure of Invention In order to solve the problems, the invention discloses a self-cleaning structure of a rear filter screen of a washing and drying integrated machine, which forms a rear end air duct structure of an outer barrel, and comprises the following components: The filter screen, the filter screen slope sets up and cuts apart the rear end wind channel into two regions. It is noted here that the gas passes under the filter screen, i.e. the trapped debris is located under the filter screen. The outside hydroecium, outside hydroecium is located the outside oblique top of filter screen, outside water hole that spouts to the filter screen has been seted up to the lower part of outside hydroecium. I.e. the outer water chamber ejects flushing liquid from obliquely above the filter screen, so that the retentate adhering to the filter screen is flushed away. The inner water chamber is positioned at the inner side of the filter screen, and an inner water hole spraying to the filter screen is formed in the inner water chamber. The inner water chamber ejects rinsing liquid to rinse the retentate from the inner side. Preferably, the inside fixedly connected with backplate structure in rear end wind channel, the inboard hydroecium is backplate structure and outer bucket enclose, inboard water hole is seted up on the upper portion of backplate structure to the quantity of inboard water hole is a plurality of. I.e. the inner water chamber is located between the back plate and the outer tub. Preferably, the upper end of the rear end air duct is fixedly connected with an inner water inlet, and the inner water inlet and the inner water chamber are communicated. Flushing liquid is injected into the inner water chamber through the inner water inlet. Preferably, the rear-end air duct comprises an outer cover plate and an inner cover plate which are arranged on the outer side, and a cavity formed between the outer cover plate and the inner cover plate is an outer water chamber. Namely, the outer water chamber is obtained after the outer cover plate and the inner cover plate are matched. Preferably, the upper end of the outer cover plate is fixedly connected with an outer water inlet, and the outer water inlet is communicated with an outer water chamber. Flushing liquid is injected into the outer water chamber through the outer water inlet. Preferably, the outer water hole is provided at a lower portion of the inner cover plate. I.e. the outside water holes are closer to the upper part of the filter screen so that the flushing of the filter screen is performed from above. The water outlet control method is characterized in that flushing liquid is pumped into the outer water chamber and the inner water chamber respectively, and the flushing liquid is sprayed out of the outer water hole and the inner water hole respectively. I.e. the flushing liquid is delivered from the outside water holes first or from the inside water Kong Songchu, or simultaneously, as desired. Preferably, the inner water Kong Xian sprays the rinsing liquid, and the outer water hole sprays the rinsing liquid. The mode selected here is that the inner water hole first goes out of the flushing liquid. Preferably, the inner water hole is then used for spraying the flushing liquid, and the outer water Ko
