Description
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.
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.
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: the mounting structure of overheat prevention device, there is mounting groove at the place at stator upper coil bracing frame, detected temperatures is arranged in the mounting groove and prevent overheated temperature sensor, and temperature sensor can insert in the mounting groove.
The position of the temperature sensor in the described mounting groove and the inner peripheral surface of stator coil are tangent, and there is the retaining platform at the mounting groove place, 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.
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.
As Fig. 3, shown in Figure 4, stator 16 in the motor for vacuum cleaner of this invention by the open iron core thin plate in a plurality of upper and lower both sides pile up the stator core 17 that forms and will insert rotor, the coil of inboard, stator core 17 open end in, have at least a pair ofly have the astragal portion 18 of polarity, coil support frame 119 compositions of formation one on the upper and lower side iron core thin plate of astragal portion 18.
Coil support frame 119 is by the coil support arc plate 119a of will be in the spiral portion 18 outstanding both sides elongated segment combination, at the end of coil support arc plate 119a, to the outstanding export-oriented boss 119b in the outside, open end of stator core, in the inboard of export-oriented boss 119b, fixedly the retaining platform 119d of both sides coil support arc plate 119a forms.Thereby, having formed the mounting groove 119c that inserts fixed temperature sensor, the shape of mounting groove 119c is consistent with temperature sensor 20 profiles.
Temperature sensor 20, after being inserted in the mounting groove 119c that forms on the coil support frame 119 export-oriented boss 119b of spiral portion 18 upper and lower both sides, coil 22 by the retaining platform 119d that forms at both sides coil support arc plate 119a and outside being wound into is fixing, temperature sensor and rotor outer circumference surface are tangent, and retaining platform 119d contacts rotor and temperature sensor portion.
Temperature sensor 20 when motor for vacuum cleaner starts, is measured the heat of coil 22 generations that are wrapped on the coil support frame and behind the heat of stator 16 spiral portions 18 certain distance rotor rotated, 13 coils generation, detection signal is delivered to control part.At this moment, judge detection signal by control part, the action of control action mechanism 10 prevents that coil is overheated.
