Description
Technical field
The present invention relates to roller washing machine, relate in particular to the mounting structure of its motor.
Background technology
General washing machine is the machine that the percussion by the decomposition of chemistry and machinery is removed the dirt on the washings or foul.
Wherein, roller washing machine can reduce whole height than the agitator washing machine of endways rotation sink (inside groove), and can increase capacity, and problem such as take place that washings tangles hardly is so the trend that the demand of roller washing machine is tending towards rising gradually.
Below with reference to back accompanying drawing 1,2,3,4, the structure of general roller washing machine is elaborated.
Roller washing machine comprises sink (2), washing inside groove (3) and drive division substantially.Sink (2) is supported on body (1) by brake and spring; The cylindrical shape of sink (3) can be arranged in the sink rotatably; Drive division and sink carry out axle and link.
Drive division is arranged on the back of sink (2), and drive division is made of rotor (Rotor) (4) and stator (stator) (5).For the driving force with rotor does not directly send washing inside groove (3) to by pulley (pulley) or conveyer belt (belt), make the wash shaft (6) of rotating directly be attached on the rotor (4) with sink.
The front of body (1) is provided with door (9), and door (9) is arranged on the ad-hoc location corresponding with the peristome that washs inside groove (3), is provided with liner (gascket) (10) between door (9) and washing inside groove (3).Liner (gascket) (10) is used to keep the sealing in the sink.
In having the roller washing machine of said structure, the revolving force of rotor (4) passes to washing inside groove (3) by wash shaft (6), along with washing inside groove rotation, (3a) mentions washings by baffle plate (baffle), washings descends by gravity more then, finishes washing stroke.
In having the roller washing machine of said structure, for motor is installed, utilization is formed on the axle sleeve that is used for fixing washing tank carriage (210) on the rear wall parts of sink (2), make washing tank carriage (11) secure bond in sink (2) rear wall parts, make stator (5) secure bond then in washing tank carriage (11).
That is to say, in prior art, for washing tank carriage (11) being fixed on sink (2) rear wall parts, by the inboard secure bond hole (110a) and the secure bond hole, the outside (110b) of washing tank carriage (11), each screw (screw) (150) or bolt (170) secure bond are on the axle sleeve that is used for fixing washing tank carriage (210) of sink rear wall parts.For stator (5) is fixed on the washing tank carriage (11), by each patchhole (520) on the stator (5), with the nut location (120) of bolt (170) secure bond on washing tank carriage (11).
On the one hand, in the above-mentioned explanation, the reason that washing tank carriage (11) is set on the rear wall parts of sink (2) is in order to improve the rigidity of injection molded thing sink (2), to be used for simultaneously providing fixing position to stator.
But the prior art electric motor mounting structure with said structure has following shortcoming.
As shown in Figure 3 and Figure 4, above-mentioned sink (2) rear wall parts one side is formed with and forwards has been recessed to form depressed part.Side in corresponding therewith washing tank carriage (11) also is formed with depressed part (100), and this depressed part (100) is used to be provided with to the connector (530) of stator (5) supply power supply and Hall element (hollsensor) etc.
So when injection molded, resin can not fill up on the depressed part of sink (2) rear wall parts, and make that the intensity of sink (2) is low, because the depressed part on sink (2) rear wall parts and the depressed part (100) of washing tank carriage (11), make that the shape of sink (2) and washing tank carriage (11) is asymmetric, so their center of gravity is inconsistent, cause having increased vibration and noise.
In addition, there is not the secure bond hole in the part of the connector depressed part (100) that forms washing tank carriage (11), so can't utilize screw (screw) (150) or bolt (170) to carry out secure bond in this part.
So, for this part, weakened the fixing and bonding force of sink (2) and washing tank carriage (11), and then washing tank carriage (11) can't correctly be carried out reinforcement to the rigidity of sink (2).
On the one hand, in the secure bond structure of prior art, stator (5) only is combined on the sink (2), along with the fixing and bonding force between sink (2) and the washing tank carriage (11) weakens, has also weakened the bed knife of stator (5).
Summary of the invention
In order to overcome the above-mentioned shortcoming that prior art exists, the invention provides a kind of electric motor mounting structure of roller washing machine, to improve the rigidity of sink, the while is fixed stator stably.
The technical solution adopted for the present invention to solve the technical problems is:
