Description

The motor for vacuum cleaner that has structure for mounting overheat prevention device
Technical field
The invention belongs to machine field, particularly a kind of motor for vacuum cleaner.
Background technology
Fig. 1 is the fragmentary cross-sectional view of traditional motor for vacuum cleaner.Fig. 2 is the structure for mounting overheat prevention device stereogram of traditional motor for vacuum cleaner.
As depicted in figs. 1 and 2, traditional suction cleaner using motor provide after by energising revolving force motor 10, be subjected to the revolving force that motor 10 transmits and produce the vacuum generator 30 of suction, the control part (not shown) of accepting to control from the signal that temperature sensor 20 is passed on motor is formed.
Motor 10 by phase changer 12 and rotor 13 are pressed into rotating shaft 14, the stator 16 that is fixed on rotor 13 outer cylinders that is fixed on the same axle, the framework 11 that is arranged on upside supporting rotating shaft 14 rotations of stator 16, in the upper end of framework 11 both sides, contact with each sliding surface of phase changer 12 both sides, provide the brush of power supply to constitute.
Vacuum generator 30 has the vacuum generator of a plurality of connection combinations to cover 31, cover 31 inboards at vacuum generator, utilize fixed cover 34 combine with rotating shaft 14 rotation and provide suction vacuum generator wheel 33, run through rotating shaft 14, for make the rotating shaft rotation inserts in conjunction with and vacuum generator frame 32 compositions of supporting rotating shaft.
Control device accepts to detect the signal of the temperature sensor 20 of the coil 22 generation heats on the stator 16, the power supply of control motor 10.
Stator 16 by the open a plurality of iron core thin plates in upper and lower both sides pile up form and make the rotor of insertion be convenient to rotational stator iron core 17, in the coil 22 of the inboard, open end of stator core 17, have at least a pair ofly have the astragal portion 18 of polarity, in stator core 17, with astragal portion 18 inside end, side thickness is thicker up and down the iron core thin plate outside prolongs and the coil support arc plate 19a of combination, and the coil support frame 19 that comprises the outer lug boss 19b that coil support arc plate 19a end is prolonged laterally and form is formed.
Bottom at spiral portion 18 outsides and coil support frame 19, continuous several times has been twined coil 22, and it is tangent with coil 22 outsides that are wrapped in the inboard spiral of stator core 17 portion 18 to be the temperature sensor that makes the heat that produces on the magnetic test coil, utilizes fixed band to be fixed on the lower end of coil support frame 19 export-oriented boss 19b temperature sensor 20.
Thus, the structure for mounting overheat prevention device of traditional motor for vacuum cleaner has been installed temperature sensor 20 because of utilizing fixed band 21, so make the increase of job engineering number, manufacturability reduces.And temperature sensor 20 can damage when the tension adjustment of fixed band is bad.
Because temperature sensor 20 has been arranged on the outside of the coil 22 of stator 16, thereby transducer is determination object with stator 16 coils only, reduced accuracy.Again, along with the winding state of coil 22, contact area is also lack of standardization, and the sensitivity during detected temperatures is lower.
Summary of the invention
Technical problem to be solved by this invention is, a kind of motor for vacuum cleaner that has structure for mounting overheat prevention device is provided, and can prevent that the excessive temperature of stator and rotor coil from rising.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: have structure for mounting overheat prevention device at stator upper coil bracing frame place, formed the mounting groove that inserts fixed temperature sensor in inboard, detected temperatures has been arranged in the mounting groove and prevent overheated temperature sensor to the outstanding export-oriented boss in the outside, open end of stator core.
The position of the temperature sensor in the described mounting groove and the inner peripheral surface of stator coil are tangent, and mounting groove is formed with the retaining platform on the coil support arc plate of both sides, and the retaining platform is fixed temperature sensor.
The shape that is shaped as pane of described mounting groove.
The invention has the beneficial effects as follows; in this invention; provide and extended to the coil support frame inboard that the upper and lower side of stator coil protector spiral portion forms; formed and to have inserted temperature sensor mounted mounting groove, prevented to utilize the productivity decline of fixed band mounting temperature sensor generation and the damage of temperature sensor.And, detect the temperature of stator coil and the rotor coil close simultaneously, and coil is wound into the outside and the contact-making surface even contact of coil support frame with stator coil, improve the vacuum cleaner overheat protection device mounting structure of detected temperatures sensitivity.

Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail: Fig. 3 is the stator plane graph of structure for mounting overheat prevention device that has disposed the motor for vacuum cleaner of this invention, and Fig. 4 is the structure for mounting overheat prevention device stereogram of the motor for vacuum cleaner that designs of the present invention.
Adopt among the embodiment of this motor for vacuum cleaner of inventing design, all the traditional motor for vacuum cleaner with shown in Figure 1 is identical with action for basic structure.Identical parts have been used identical symbol, and the part of repeatability is omitted explanation or simply narrated.
The control part (not shown) that the motor for vacuum cleaner of this invention provides after by energising the motor 10 of revolving force, the revolving force that is subjected to motor 10 to produce the vacuum generator 30 of suction and the signal of accepting temperature sensor is controlled motor 10 is formed.
Motor 10 by phase changer 12 and rotor 13 are pressed into the electric machine rotational axis 14 that is fixed on the same axle, are fixed on the stator 16 of rotor 13 outer cylinders, the framework 11 that combines and support electric machine rotational axis to rotate with electric machine rotational axis forms.
Vacuum generator 30 is by vacuum generator frame 32 and be combined in a plurality of vacuum generators lids 31 of vacuum generator frame side and the vacuum generator of the rotation that combines with an end of rotating shaft 14 in the inboard of vacuum generator lid 31 is taken turns 33 and formed.
Control part (not shown), the temperature sensor that detects the coil generation heat on stator 16 and the rotor 13 send signal and control power supply on the motor 10.
