Abstract
The utility model relates to a circular water discharging pump for a washing machine, comprising a stator (9), a coil winding piece (11), a rotor (12), a front bearing seat (3), a back bearing seat (14), an impeller (1), a turbine casing (2), a fan (15), a thermal protector, etc. The utility model is characterized in that the thermal protector is arranged in the coil winding and the thermal protector and the coil winding are sealed with plastic to form the coil winding piece (11); the center of the seal seat (5) which is inserted in the front shaft of the rotor (12) is provided with a double-mouth sealed disc (6). The utility model has the advantages of beautiful appearance, high overheating precision of the control winding, long service life of the thermal protector, little possibility of the burning out of a pump, little possibility of axial leakage water, etc.
Description
The utility model relates to a kind of washing machine accessory, refers in particular to the circulation draining pump.
Throwing in the old-fashioned washing machine has draining pump, and draining relies on water level nature drop to realize.Be furnished with draining pump in the novel washing machine, draining rapidly and can be with washings row to the place that is higher than the washing machine oneself height, as sink; Recycle for using water wisely makes washings, also be furnished with circulating pump.Circulating pump and draining pump, their model-performance is all identical, and just the situation of installed part or water inlet, delivery port is slightly had any different.At present, this use in washing machine circulation draining pump is made of stator and coil windings part, rotor and front-end bearing pedestal and rear bearing block, impeller, volute, fan, thermal protector etc., but thermal protector is attached to coil windings part shell or other place, the one, not attractive in appearance, the 2nd, the control coil winding overheated directly perceived, the 2nd, make moist and easily lost efficacy; And existing encapsulating method is undesirable, and axial percolating water phenomenon often takes place during use.
The purpose of this utility model is to overcome the above-mentioned defective that exists in the prior art, and a kind of use in washing machine circulation draining pump is provided, and its good looking appearance, directly control coil is overheated, sealing is reliable.
For achieving the above object; the solution that the utility model is taked is: a kind of use in washing machine circulation draining pump; it comprises stator, coil windings part, rotor and front-end bearing pedestal and rear bearing block, impeller, volute, fan, thermal protector; it is characterized in that being provided with in the coil windings thermal protector and together plastic packaging constitute the coil windings part, there are two mouth seal discs at the seal receptacle center of inserting the rotor front axle.
The utility model is compared with existing use in washing machine circulation draining pump; because thermal protector is arranged in the coil windings part; so good looking appearance; the overheated precision height of control coil; thermal protector does not make moist in sealing condition, long service life; be that pump is difficult for burning; owing to seal by two mouth seal discs; water in the volute is difficult for axial seepage; the hydraulic pressure that current produce during pump startup makes the mouth shape place of two mouth seal discs wrap the rotor front axle more tightly, than seal ring seal more reliable performance used in the prior art.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.
Fig. 1 is that the present embodiment master looks fragmentary cross-sectional view.
Fig. 2 is the right pseudosection of coil windings part (11) among Fig. 1.
The following realization of present embodiment: coil windings part (11) is packed in the stator (9), rotor (12) is inserted in the stator (9), rotor (12) front axle is inserted in liner (7), rotor (12) is preceding, rear axle is inserted in lining (13) respectively, be inserted in spacer sheet (19) at rear axle, in front-end bearing pedestal (3) and rear bearing block (14), put into oil storage pad (17) respectively, spherical bearing (18) and bearing pressure pad (16), front-end bearing pedestal (3) and rear bearing block (14) be inserted in respectively rotor (12) before, rear axle also correspondingly is installed on the stator (9), and fan (15) is inserted in rear axle and ties down or enclose; Embed O RunddichtringO (4), the two mouth seal discs (6) of center embedding at seal receptacle (5) export-oriented edge, two mouth seal discs (6) at seal receptacle (5) center insert rotor (12) front axle, impeller (1) is tightened or is tied down with front axle termination threaded engagement, and O RunddichtringO (4) rotation that volute (2) combines with the export-oriented face card pushing type of front-end bearing pedestal (3), just go on the seal receptacle (5) to groove in it is tightly blocked; For safety ground, on stator (9) surface, fix a grounding wafer (10) and contact with coil windings part (11) surface; Go up kinking circle winding (23) at coil rack (20), the lead-out wire of coil windings (23) connects thermal protector (22), and thermal protector (22) is drawn male blade (8), and plastic packaging (21) constitutes coil windings part (11) together.
Claims (2)
1, a kind of use in washing machine circulation draining pump; comprise stator (9), coil windings part (11), rotor (12) and front-end bearing pedestal (3) and rear bearing block (14), impeller (1), volute (2), fan (15), thermal protector (22); it is characterized in that: be provided with in the coil windings (23) thermal protector (22) and together plastic packaging (21) constitute coil windings part (11), there are two mouth seal discs (6) at seal receptacle (5) center of inserting rotor (12) front axle.
2, a kind of use in washing machine circulation draining pump according to claim 1 is characterized in that: fix a grounding wafer (10) and contact with coil windings part (11) surface on stator (9) surface.
