Example four
Fig. 2 is a schematic structural diagram of a clothes dryer according to an embodiment of the present invention, and as shown in fig. 2, the embodiment provides a clothes dryer including a cabinet 2, a dust box disposed inside the cabinet 2, and a dust-removing docking device 1 according to the first embodiment, the second embodiment, or the third embodiment. The dust box is used for collecting the thread scraps in the clothes dryer, is arranged in a drying air duct in the clothes dryer, and comprises an air inlet for air inlet and a filter screen for filtering the thread scraps.
The tail ends of the butt joint hose 13 and the air return hose 12 of the dust removal butt joint device 1 are inserted into a dust box, a dust removal mounting port 21 is formed in the machine shell 2, the dust removal mounting port 21 is arranged right opposite to a first connecting end pipe opening of the mounting pipe 11, and a dust suction pipe 3 of dust suction equipment can be inserted into the mounting pipe 11 through the dust removal mounting port 21.
According to the clothes dryer provided by the embodiment, the dust removal butt joint device 1 in butt joint with the dust box is arranged in the clothes dryer, so that butt joint of the dust box and the dust collection equipment can be realized, the dust box in the clothes dryer can be cleaned through the dust collection equipment, manual cleaning of the dust box is avoided, the use experience of a user, especially a user suffering from allergic rhinitis and asthma, on the clothes dryer is improved, and the cleaning effect and the cleaning efficiency of the dust box are improved; the mode of cleaning the dust box in the clothes dryer by adopting the dust collection equipment is simple and quick, the filter screen in the dust box can be kept clean for a long time, the thread scraps filtering effect of the dust box is improved, the clothes drying efficiency of the clothes dryer is improved, and the service life of the clothes dryer is prolonged; and this kind of setting need not to carry out great improvement to current dryer's structure, only need set up dust removal installing port 21 on casing 2 and rationally arrange installation pipe 11, butt joint hose 13 and return-air hose 12 in casing 2 can, improve the cost lower, have better suitability.
In this embodiment, the free end of the return air hose 12 corresponds to the filter screen in the dust box, so that the return air hose 12 can freely swing in the dust removing process to knock the filter screen, and the thread scraps on the filter screen fall off under the vibration effect.
Since two or more dust boxes are usually disposed in the clothes dryer, in this embodiment, the number of the docking hoses 13 is the same as that of the dust boxes, and the number of the air return branch pipes 122 is greater than or equal to that of the dust boxes, so that the dust suction apparatus can simultaneously clean all the dust boxes inside the clothes dryer. It is understood that when the return air hose 12 is not in the form of the return air branch pipe 122 and the return air main pipe 121, the number of the return air hoses 12 is greater than or equal to the number of the dust boxes.
More preferably, the first connecting end of the mounting pipe 11 is inserted into the dust-removing mounting port 21 in a sealing manner, so that the first connecting end of the mounting pipe 11 can be ensured to be fixed relative to the case 2, and the butt joint stability and reliability of the mounting pipe 11 and the dust-collecting pipe 3 are improved.
Because the volume of each dust box in the dryer is different with the thickness degree of the thread scraps that the filtration was collected, the internal diameter of a plurality of butt joint hoses can be different, can be according to the volume of each dust box and the thickness degree of thread scraps, confirm the internal diameter that corresponds the butt joint hose. The internal diameter of the docking hose corresponding to a dust box for collecting relatively coarse lint should be larger than the internal diameter of the docking hose corresponding to a dust box for collecting relatively fine lint.
Further, when the return air hose includes at least two return air branch pipes, the inner diameters of the return air branch pipes corresponding to different dust boxes may also be different. When the air return hose is provided with at least two air return hoses, the inner diameters of the air return hoses corresponding to different dust boxes can be different.
The dust box and other structures of the clothes dryer can refer to the arrangement of the existing clothes dryer, which is not the focus of the invention, and the dust box and other structures of the clothes dryer are not particularly limited in the embodiment. And other settings of the dust removal docking device 1 can refer to the first setting of the embodiment, which is not described in detail in this embodiment.
In order to improve the cleaning effect and cleaning efficiency for the plurality of dust boxes, the dust suction apparatus preferably employs a bucket type dust collector, that is, the outer diameter of the dust suction pipe 3 of the bucket type dust collector is equal to or greater than the minimum inner diameter of the tapered pipe portion 111 and less than the maximum inner diameter of the tapered pipe portion 111. The capacity of dust collection box is great in the bucket formula dust catcher, when can guaranteeing the clearance demand of all dust collection boxes in the clothes dryer, can also reduce the clearance number of times to dust collection box in the dust collecting equipment, realizes that the dust after the clearance many times concentrates and emptys, improves and uses experience.
It is to be noted that the foregoing is only illustrative of the preferred embodiments of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail by the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the spirit of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
