Description
Technical Field
The invention relates to a water pump. In particular to a drainage pump on a clothes dryer for drying the washed clothes containing water.
Background
As known in the dryer manufacturing industry, the drainage pumps currently used in dryers are all traditional products. Such conventional products include a housing having a rotor assembly therein and a stator assembly therein on one side of the rotor assembly. The rotor assembly comprises a cylindrical shell, a rotor is arranged in the cylindrical shell, and the rotor is composed of a shaft and magnetic steel fixed on the shaft. The two ends of the shaft are respectively matched with the two ends of the cylindrical shell in a sealing and rotatable manner by virtue of bearings. One end of the cylindrical shell is provided with a water cavity, and the water cavity is provided with a water inlet and a water outlet. One end of the shaft extends into the water cavity. An impeller is arranged in the water cavity, a blind hole is formed in the center of the impeller, and one end of the shaft is directly installed in the blind hole in the center of the impeller. Because one end of the shaft is directly arranged in the blind hole in the center of the impeller, no vibration reduction measure exists between one end of the shaft and the blind hole in the center of the impeller, and the shaft and the blind hole are in rigid connection, the drainage pump has large vibration and high noise when in work.
Disclosure of Invention
The invention provides a drainage pump for a clothes dryer. The draining pump for the clothes dryer has the advantages of small vibration and low noise.
The above problems to be solved by the present invention are realized by the following technical solutions: the draining pump for clothes dryer of the present invention includes one casing, one rotor assembly inside the casing, and one stator assembly inside the casing beside the rotor assembly. The rotor assembly comprises a cylindrical shell, a rotor is arranged in the cylindrical shell, and the rotor is composed of a shaft and magnetic steel fixed on the shaft. The two ends of the shaft are respectively matched with the two ends of the cylindrical shell in a sealing and rotatable manner by virtue of bearings; one end of the cylindrical shell is provided with a water cavity, and the water cavity is provided with a water inlet and a water outlet. One end of the shaft extends into the water cavity. The impeller is arranged in the water cavity, the center of the impeller is provided with a blind hole, the impeller is characterized in that a rubber sleeve is arranged in the blind hole, and one end of the shaft is fixedly arranged in the blind hole in the center of the impeller by means of the rubber sleeve.
The rubber sleeve is a short round tube, one end of the short round tube is provided with a back cover, and one end of the short round tube with the back cover is positioned at the bottom of the blind hole in the center of the impeller.
By adopting the scheme, the method has the following advantages: according to the scheme, the rubber sleeve is arranged in the blind hole, one end of the shaft is fixedly arranged in the blind hole in the center of the impeller by means of the rubber sleeve, and a vibration reduction measure is adopted between one end of the shaft and the blind hole in the center of the impeller to ensure that the shaft and the blind hole are in flexible connection, so that vibration is reduced and noise is reduced when the drainage pump works.

FIG. 1 is a schematic diagram of a dryer drain pump of the present invention;
fig. 2 is a schematic sectional view a-a of fig. 1.
Detailed Description
As shown in fig. 1 and 2, the drain pump for the clothes dryer of the present invention includes a cabinet 1, a rotor assembly is provided in the cabinet 1, and a stator assembly 2 is installed in the cabinet 1 at one side of the rotor assembly. The rotor assembly comprises a cylindrical shell 3, a rotor is arranged in the cylindrical shell 3, and the rotor is composed of a shaft 6 and magnetic steel 5 fixed on the shaft 6. The two ends of the shaft 6 are respectively matched with the two ends of the cylindrical shell 3 in a sealing and rotatable manner through bearings. One end of the cylindrical shell 3 is provided with a water cavity 14, and a water inlet 12 and a water outlet 4 are processed on the water cavity 14; one end of the shaft 6 extends into the water chamber 14. Wherein, the shaft 6 between the water cavity 14 and the magnetic steel 5, namely, one end of the shaft 6 adjacent to the water cavity 14 is in sealed and rotatable fit with the cylindrical shell 3 by virtue of a first sliding bearing 7, a sealing sleeve 8, an annular support 9 and a pressure sheet 10, and the end of the shaft 6 far away from the water cavity 14 is in sealed and rotatable fit with the cylindrical shell 3 by virtue of a second sliding bearing 16. An impeller 15 is arranged in the water cavity 14, a blind hole is machined in the center of one side, close to the impeller 15, of the pressing plate 10, a rubber sleeve 13 is installed in the blind hole, and one end of the shaft 6 is fixedly installed in the blind hole in the center of the impeller 12 through the rubber sleeve 13. The rubber sleeve 13 is a short circular tube, a back cover is processed at one end of the short circular tube, and one end of the short circular tube with the back cover is positioned at the bottom of the blind hole in the center of the impeller 15. The rubber sleeve 13 is arranged in the blind hole, vibration reduction measures are added, the rubber sleeve and the blind hole are flexibly connected, and therefore vibration and noise are reduced when the drainage pump works.
